1441_32 | Under the Rail Passenger Service Act of 1970, Congress created the National Railroad Passenger Corporation (NRPC) to subsidize and oversee the operation of intercity passenger trains. The Act provided that
Any railroad operating intercity passenger service could contract with the NRPC, thereby joining the national system.
Participating railroads bought into the new corporation using a formula based on their recent intercity passenger losses. The purchase price could be satisfied either by cash or rolling stock; in exchange, the railroads received Amtrak common stock.
Any participating railroad was freed of the obligation to operate intercity passenger service after May 1971, except for those services chosen by the U.S. Department of Transportation as part of a "basic system" of service and paid for by NRPC using its federal funds. |
1441_33 | Railroads who chose not to join the Amtrak system were required to continue operating their existing passenger service until 1975 and thenceforth had to pursue the customary ICC approval process for any discontinuance or alteration to the service. |
1441_34 | The original working brand name for NRPC was Railpax, which eventually became Amtrak. At the time, many Washington insiders viewed the corporation as a face-saving way to give passenger trains the one "last hurrah" demanded by the public, but expected that the NRPC would quietly disappear in a few years as public interest waned. However, while Amtrak's political and financial support have often been shaky, popular and political support for Amtrak has allowed it to survive into the 21st century. |
1441_35 | Similarly, to preserve a declining freight rail industry, Congress passed the Regional Rail Reorganization Act of 1973 (sometimes called the "3R Act"). The act was an attempt to salvage viable freight operations from the bankrupt Penn Central and other lines in the northeast, mid-Atlantic and Midwestern regions. The law created the Consolidated Rail Corporation (Conrail), a government-owned corporation, which began operations in 1976. Another law, the Railroad Revitalization and Regulatory Reform Act of 1976 (the "4R Act"), provided more specifics for the Conrail acquisitions and set the stage for more comprehensive deregulation of the railroad industry. Portions of the Penn Central, Erie Lackawanna, Reading Railroad, Ann Arbor Railroad, Central Railroad of New Jersey, Lehigh Valley, and Lehigh and Hudson River were merged into Conrail. |
1441_36 | The freight industry continued its decline until Congress passed the Staggers Rail Act in 1980, which largely deregulated the rail industry. Since then, U.S. freight railroads have reorganized, discontinued their lightly used routes and returned to profitability.
Freight railroads
Freight railroads play an important role in the U.S. economy, especially for moving imports and exports using containers, and for shipments of coal and oil. According to the British news magazine The Economist, "They are universally recognised in the industry as the best in the world." Productivity rose 172% between 1981 and 2000, while rates decreased by 55% (after accounting for inflation). Rail's share of the American freight market rose to 43%, the highest for any rich country. |
1441_37 | U.S. railroads still play a major role in the nation's freight shipping. They carried 750 billion ton-miles by 1975 which doubled to 1.5 trillion ton-miles in 2005. In the 1950s, the U.S. and Europe moved roughly the same percentage of freight by rail; by 2000, the share of U.S. rail freight was 38% while in Europe only 8% of freight traveled by rail. In 2000, while U.S. trains moved 2,390 billion ton-kilometers of freight, the 15-nation European Union moved only 304 billion ton-kilometers of freight. In terms of ton-miles, railroads annually move more than 25% of the United States' freight and connect businesses with each other across the country and with markets overseas. In 2018, US rail freight had a transport energy efficiency of 473 tons.miles per gallon of fuel. |
1441_38 | U.S. freight railroads are separated into three classes, set by the Surface Transportation Board, based on annual revenues:
Class I for freight railroads with annual operating revenues above $346.8 million in 2006 dollars. In 1900, there were 132 Class I railroads. Today, as the result of mergers, bankruptcies, and major changes in the regulatory definition of "Class I", there are only seven railroads operating in the United States that meet the criteria for Class I. , U.S. freight railroads operated 139,679 route-miles (224,792 km) of standard gauge in the U.S. Although Amtrak qualifies for Class I status under the revenue criteria, it is not considered a Class I railroad because it is not a freight railroad.
Class II for freight railroads with revenues between $27.8 million and $346.7 million in 2000 dollars
Class III for all other freight revenues. |
1441_39 | In 2013, the U.S. moved more oil out of North Dakota by rail than by the Trans-Alaska pipeline. This trend—tenfold in two years and 40-fold in five years—is forecast to increase.
Classes of freight railroads
There are four different classes of freight railroads: Class I, regional, local line haul, and switching & terminal. Class I railroads are defined as those with revenue of at least $346.8 million in 2006. They comprise just one percent of the number of freight railroads, but account for 67 percent of the industry's mileage, 90 percent of its employees, and 93 percent of its freight revenue.
A regional railroad is a line haul railroad with at least and/or revenue between $40 million and the Class I threshold. There were 33 regional railroads in 2006. Most have between 75 and 500 employees. |
1441_40 | Local line haul railroads operate less than and earn less than $40 million per year (most earn less than $5 million per year). In 2006, there were 323 local line haul railroads. They generally perform point-to-point service over short distances.
Switching and terminal (S&T) carriers are railroads that primarily provide switching and/or terminal services, regardless of revenue. They perform pick up and delivery services within a certain area.
Traffic and public benefits
U.S. freight railroads operate in a highly competitive marketplace. In 2011, within the U.S., railroads carried 39.9% of freight by ton-mile, followed by trucks (33.4%), oil pipelines (14.3%), barges (12%) and air (0.3%). However, railroads' revenue share has been slowly falling for decades, a reflection of the intensity of the competition they face and of the large rate reductions railroads have passed through to their customers over the years. |
1441_41 | North American railroads operated 1,471,736 freight cars and 31,875 locomotives, with 215,985 employees. They originated 39.53 million carloads (averaging 63 tons each) and generated $81.7 billion in freight revenue of present 2014. The average haul was 917 miles. The largest (Class 1) U.S. railroads carried 10.17 million intermodal containers and 1.72 million piggyback trailers. Intermodal traffic was 6.2% of tonnage originated and 12.6% of revenue. The largest commodities were coal, chemicals, farm products, nonmetallic minerals and intermodal. Other major commodities carried include lumber, automobiles, and waste materials. Coal alone was 43.3% of tonnage and 24.7% of revenue. Coal accounted for roughly half of U.S. electricity generation and was a major export. As natural gas became cheaper than coal, coal supplies dropped 11% in 2015 but coal rail freight dropped by up to 40%, allowing an increase in car transport by rail, some in tri-level railcars. US coal consumption dwindled |
1441_42 | from over 1,100 million tons in 2008 to 687 million tons in 2018. |
1441_43 | The fastest growing rail traffic segment is currently intermodal. Intermodal is the movement of shipping containers or truck trailers by rail and at least one other mode of transportation, usually trucks or ocean-going vessels. Intermodal combines the door-to-door convenience of trucks with the long-haul economy of railroads. Rail intermodal has tripled in the last 25 years. It plays a critical role in making logistics far more efficient for retailers and others. The efficiency of intermodal provides the U.S. with a huge competitive advantage in the global economy. A major factor in making U.S. rail intermodal freight competitive is the use of double-stack rail transport, where shipping containers are loaded two-high on special freight cars, potential doubling the number of containers one train can carry, with corresponding reductions in operating costs. |
1441_44 | Freight rail working with passenger rail
Prior to Amtrak's creation in 1970, intercity passenger rail service in the U.S. was provided by the same companies that provided freight service. When Amtrak was formed, in return for government permission to exit the passenger rail business, freight railroads donated passenger equipment to Amtrak and helped it get started with a capital infusion of some $200 million.
The vast majority of the 22,000 or so miles over which Amtrak operates are actually owned by freight railroads. By law, freight railroads must grant Amtrak access to their track upon request. In return, Amtrak pays fees to freight railroads to cover the incremental costs of Amtrak's use of freight railroad tracks.
Passenger railroads |
1441_45 | The sole long-distance intercity passenger railroad in the continental U.S. is Amtrak, although Brightline plans to provide intercity service between Orlando and Miami, and multiple current commuter rail systems provide regional intercity services such as New York-New Haven, Stockton-San Jose and West Palm Beach-Miami. In Alaska, intercity service is provided by Alaska Railroad instead of Amtrak. Commuter rail systems exist in more than a dozen metropolitan areas, but these systems are not extensively interconnected, so commuter rail cannot be used alone to traverse the country. Commuter systems have been proposed in approximately two dozen other cities, but interplays between various local-government administrative bottlenecks and ripple effects from the 2007–2012 global financial crisis have generally pushed such projects farther and farther into the future, or have even sometimes mothballed them entirely. |
1441_46 | The most culturally notable and physically evident exception to the general lack of significant passenger rail transport in the U.S. is the Northeast Corridor between Washington, Baltimore, Philadelphia, New York City, and Boston, with significant branches in Connecticut and Massachusetts. The corridor handles frequent passenger service that is both Amtrak and commuter. New York City itself is noteworthy for high usage of passenger rail transport, both subway and commuter rail (Long Island Rail Road, Metro-North Railroad, New Jersey Transit). The subway system is used by one third of all U.S. mass transit users. Chicago also sees high rail ridership, with a local elevated system, one of the world's last interurban lines, and fourth most-ridden commuter rail system in the United States: Metra. Other major cities with substantial rail infrastructure include Philadelphia's SEPTA, Boston's MBTA, and Washington, D.C.'s network of commuter rail and rapid transit. Denver, Colorado |
1441_47 | constructed a new electrified commuter rail system in the 2000s to complement the city's light rail system. The commuter rail systems of San Diego and Los Angeles, Coaster and Metrolink, connect in Oceanside, California. The San Francisco Bay Area additionally hosts several local rail operators. |
1441_48 | Privately run inter-city passenger rail operations have also been restarted since 2018 in south Florida, with additional routes under development. Brightline is a higher-speed rail train, run by All Aboard Florida. It began service in January 2018 between Fort Lauderdale and West Palm Beach; its service was extended to Miami in May 2018, with an extension to Orlando International Airport planned by 2022. Brightline has also proposed a further extension of its service from Orlando to Tampa via Walt Disney World, and a high-speed rail service from Victorville, California to Las Vegas. In addition, the Texas Central Railway is currently developing plans for a proposed greenfield high-speed rail line using Japanese Shinkansen trains between Dallas and Houston, which is expected to begin construction in 2020 and open in early 2026. |
1441_49 | Car types
The basic design of a passenger car was standardized by 1870. By 1900, the main car types were: baggage, coach, combine, diner, dome car, lounge, observation, private, Pullman, railroad post office (RPO) and sleeper.
19th century: First passenger cars and early development
The first passenger cars resembled stagecoaches. They were short, often less than long, tall and rode on a single pair of axles.
American mail cars first appeared in the 1860s and at first followed English design. They had a hook that would catch the mailbag in its crook. |
1441_50 | As locomotive technology progressed in the mid-19th century, trains grew in length and weight. Passenger cars grew along with them, first getting longer with the addition of a second truck (one at each end), and wider as their suspensions improved. Cars built for European use featured side door compartments, while American car design favored a single pair of doors at one end of the car in the car's vestibule; compartmentized cars on American railroads featured a long hallway with doors from the hall to the compartments. |
1441_51 | One possible reason for this difference in design principles between American and European carbuilding practice could be the average distance between stations on the two continents. While most European railroads connected towns and villages that were still very closely spaced, American railroads had to travel over much greater distances to reach their destinations. Building passenger cars with a long passageway through the length of the car allowed the passengers easy access to the restroom, among other things, on longer journeys.
Dining cars first appeared in the late 1870s and into the 1880s. Until this time, the common practice was to stop for meals at restaurants along the way (which led to the rise of Fred Harvey's chain of Harvey House restaurants in America). At first, the dining car was simply a place to serve meals that were picked up en route, but they soon evolved to include galleys in which the meals were prepared.
1900–1950: Lighter materials, new car types |
1441_52 | By the 1920s, passenger cars on the larger standard gauge railroads were normally between long. The cars of this time were still quite ornate, many of them being built by experienced coach makers and skilled carpenters.
With the 1930s came the widespread use of stainless steel for car bodies. The typical passenger car was now much lighter than its "heavyweight" wood cousins of old. The new "lightweight" and streamlined cars carried passengers in speed and comfort to an extent that had not been experienced to date. Aluminum and Cor-ten were also used in lightweight car construction, but stainless steel was the preferred material for car bodies. It is not the lightest of materials, nor is it the least expensive, but stainless steel cars could be, and often were, left unpainted except for the car's reporting marks that were required by law. |
1441_53 | By the end of the 1930s, railroads and car builders were debuting car body and interior styles that could only be dreamed of before. In 1937, the Pullman Company delivered the first cars equipped with roomettes—that is, the car's interior was sectioned off into compartments, much like the coaches that were still in widespread use across Europe. Pullman's roomettes, however, were designed with the single traveler in mind. The roomette featured a large picture window, a privacy door, a single fold-away bed, a sink and small toilet. The roomette's floor space was barely larger than the space taken up by the bed, but it allowed the traveler to ride in luxury compared to the multilevel semiprivate berths of old. |
1441_54 | Now that passenger cars were lighter, they were able to carry heavier loads, but the size of the average passenger load that rode in them didn't increase to match the cars' new capacities. The average passenger car couldn't get any wider or longer due to side clearances along the railroad lines, but they generally could get taller because they were still shorter than many freight cars and locomotives. As a result, the railroads soon began building and buying dome and bilevel cars to carry more passengers.
1950–present: High-technology advancements
Carbody styles have generally remained consistent since the middle of the 20th century. While new car types have not made much of an impact, the existing car types have been further enhanced with new technology. |
1441_55 | Starting in the 1950s, the passenger travel market declined in North America, though there was growth in commuter rail. The higher clearances in North America enabled bi-level commuter coaches that could hold more passengers. These cars started to become common in the United States in the 1960s. |
1441_56 | While intercity passenger rail travel declined in the United States during the 1950s, ridership continued to increase in Europe during that time. With the increase came newer technology on existing and new equipment. The Spanish company Talgo began experimenting in the 1940s with technology that would enable the axles to steer into a curve, allowing the train to move around the curve at a higher speed. The steering axles evolved into mechanisms that would also tilt the passenger car as it entered a curve to counter the centrifugal force experienced by the train, further increasing speeds on existing track. Today, tilting passenger trains are commonplace. Talgo's trains are used on some short and medium distance routes such as Amtrak Cascades from Eugene, Oregon, to Vancouver, British Columbia. |
1441_57 | In August 2016, the Department of Transportation approved the largest loan in the department's history, $2.45 billion to upgrade the passenger train service in the Northeast region. The $2.45 billion will be used to purchase 28 new train sets for the high-speed Acela train between Washington through Philadelphia, New York and into Boston. The money will also be used build new stations and platforms. The money will also be used to rehabilitate railroad tracks and upgrade four stations, including Washington's Union Station and Baltimore's Penn Station.
High-speed rail |
1441_58 | There is currently only one operating high speed line in the US, Amtrak's Acela Express between Washington, DC, and Boston. It currently has a maximum speed of , and only in some sections between Boston and Providence, RI, soon to be after introduction of new Avelia Liberty trains, eventually to be upgraded to over some sections. The state of California is constructing its own HSR system, California High-Speed Rail, constructed to standards in some places. The first section in the Central Valley is due to open around 2027. |
1441_59 | Rolling stock reporting marks
Every piece of railroad rolling stock operating in North American interchange service is required to carry a standardized set of reporting marks. The marks are made up of a two- to four-letter code identifying the owner of the equipment accompanied by an identification number and statistics on the equipment's capacity and tare (unloaded) weight. Marks whose codes end in X (such as TTGX) are used on equipment owned by entities that are not common carrier railroads themselves. Marks whose codes end in U are used on containers that are carried in intermodal transport, and marks whose codes end in Z are used on trailers that are carried in intermodal transport, per ISO standard 6346). Most freight cars carry automatic equipment identification RFID transponders. |
1441_60 | Typically, railroads operating in the United States reserve one- to four-digit identification numbers for powered equipment such as diesel locomotives and six-digit identification numbers for unpowered equipment. There is no hard and fast rule for how equipment is numbered; each railroad maintains its own numbering policy for its equipment.

1441_61 | Regulation
Federal regulation of railroads is mainly through the United States Department of Transportation, especially the Federal Railroad Administration which regulates safety, and the Surface Transportation Board which regulates rates, service, the construction, acquisition and abandonment of rail lines, carrier mergers and interchange of traffic among carriers.
Railroads are also regulated by the individual states, for example through the Massachusetts Department of Public Utilities.

1442_0 | A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.
Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.01 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional vacuum between the parietal and visceral pleurae. Excess fluid within the pleural space can impair inspiration by upsetting the functional vacuum and hydrostatically increasing the resistance against lung expansion, resulting in a fully or partially collapsed lung. |
1442_1 | Various kinds of fluid can accumulate in the pleural space, such as serous fluid (hydrothorax), blood (hemothorax), pus (pyothorax, more commonly known as pleural empyema), chyle (chylothorax), or very rarely urine (urinothorax). When unspecified, the term "pleural effusion" normally refers to hydrothorax. A pleural effusion can also be compounded by a pneumothorax (accumulation of air in the pleural space), leading to a hydropneumothorax.
Types
Various methods can be used to classify pleural fluid.
By the origin of the fluid:
Serous fluid (hydrothorax)
Blood (haemothorax)
Chyle (chylothorax)
Pus (pyothorax or empyema)
Urine (urinothorax)
By pathophysiology:
Transudative pleural effusion
Exudative pleural effusion
By the underlying cause (see next section).
Causes |
1442_2 | Transudative
The most common causes of transudative pleural effusion in the United States are heart failure and cirrhosis. Nephrotic syndrome, leading to the loss of large amounts of albumin in urine and resultant low albumin levels in the blood and reduced colloid osmotic pressure, is another less common cause of pleural effusion. Pulmonary emboli were once thought to cause transudative effusions, but have been recently shown to be exudative.
The mechanism for the exudative pleural effusion in pulmonary thromboembolism is probably related to increased permeability of the capillaries in the lung, which results from the release of cytokines or inflammatory mediators (e.g. vascular endothelial growth factor) from the platelet-rich blood clots. The excessive interstitial lung fluid traverses the visceral pleura and accumulates in the pleural space. |
1442_3 | Conditions associated with transudative pleural effusions include:
Congestive heart failure
Liver cirrhosis
Severe hypoalbuminemia
Nephrotic syndrome
Acute atelectasis
Myxedema
Peritoneal dialysis
Meigs's syndrome
Obstructive uropathy
End-stage kidney disease
Exudative |
1442_4 | When a pleural effusion has been determined to be exudative, additional evaluation is needed to determine its cause, and amylase, glucose, pH and cell counts should be measured.
Red blood cell counts are elevated in cases of bloody effusions (for example after heart surgery or hemothorax from incomplete evacuation of blood).
Amylase levels are elevated in cases of esophageal rupture, pancreatic pleural effusion, or cancer.
Glucose is decreased with cancer, bacterial infections, or rheumatoid pleuritis.
pH is low in empyema (<7.2) and maybe low in cancer.
If cancer is suspected, the pleural fluid is sent for cytology. If cytology is negative, and cancer is still suspected, either a thoracoscopy, or needle biopsy of the pleura may be performed.
Gram staining and culture should also be done. |
1442_5 | If tuberculosis is possible, examination for Mycobacterium tuberculosis (either a Ziehl–Neelsen or Kinyoun stain, and mycobacterial cultures) should be done. A polymerase chain reaction for tuberculous DNA may be done, or adenosine deaminase or interferon gamma levels may also be checked. |
1442_6 | The most common causes of exudative pleural effusions are bacterial pneumonia, cancer (with lung cancer, breast cancer, and lymphoma causing approximately 75% of all malignant pleural effusions), viral infection, and pulmonary embolism.
Another common cause is after heart surgery when incompletely drained blood can lead to an inflammatory response that causes exudative pleural fluid.
Conditions associated with exudative pleural effusions:
Parapneumonic effusion due to pneumonia
Malignancy (either lung cancer or metastases to the pleura from elsewhere)
Infection (empyema due to bacterial pneumonia)
Trauma
Pulmonary infarction
Pulmonary embolism
Autoimmune disorders
Pancreatitis
Ruptured esophagus (Boerhaave's syndrome)
Rheumatoid pleurisy
Drug-induced lupus |
1442_7 | Other/ungrouped
Other causes of pleural effusion include tuberculosis (though stains of pleural fluid are only rarely positive for acid-fast bacilli, this is the most common cause of pleural effusions in some developing countries), autoimmune disease such as systemic lupus erythematosus, bleeding (often due to chest trauma), chylothorax (most commonly caused by trauma), and accidental infusion of fluids. Less common causes include esophageal rupture or pancreatic disease, intra-abdominal abscesses, rheumatoid arthritis, asbestos pleural effusion, mesothelioma, Meigs's syndrome (ascites and pleural effusion due to a benign ovarian tumor), and ovarian hyperstimulation syndrome. |
1442_8 | Pleural effusions may also occur through medical or surgical interventions, including the use of medications (pleural fluid is usually eosinophilic), coronary artery bypass surgery, abdominal surgery, endoscopic variceal sclerotherapy, radiation therapy, liver or lung transplantation, insertion of ventricular shunt as a treatment method of hydrocephalus, and intra- or extravascular insertion of central lines.
Pathophysiology
Pleural fluid is secreted by the parietal layer of the pleura and reabsorbed by the lymphatics in the most dependent parts of the parietal pleura, primarily the diaphragmatic and mediastinal regions. Exudative pleural effusions occur when the pleura is damaged, e.g., by trauma, infection, or malignancy, and transudative pleural effusions develop when there is either excessive production of pleural fluid or the resorption capacity is reduced. Light's criteria can be used to differentiate between exudative and transudative pleural effusions.
Diagnosis |
1442_9 | A pleural effusion is usually diagnosed on the basis of medical history and physical exam, and confirmed by a chest X-ray. Once accumulated fluid is more than 300 mL, there are usually detectable clinical signs, such as decreased movement of the chest on the affected side, dullness to percussion over the fluid, diminished breath sounds on the affected side, decreased vocal resonance and fremitus (though this is an inconsistent and unreliable sign), and pleural friction rub. Above the effusion, where the lung is compressed, there may be bronchial breathing sounds and egophony. A large effusion there may cause tracheal deviation away from the effusion. A systematic review (2009) published as part of the Rational Clinical Examination Series in the Journal of the American Medical Association showed that dullness to conventional percussion was most accurate for diagnosing pleural effusion (summary positive likelihood ratio, 8.7; 95% confidence interval, 2.2–33.8), while the absence of |
1442_10 | reduced tactile vocal fremitus made pleural effusion less likely (negative likelihood ratio, 0.21; 95% confidence interval, 0.12–0.37). |
1442_11 | Imaging |
1442_12 | A pleural effusion appears as an area of whiteness on a standard posteroanterior chest X-ray. Normally, the space between the visceral pleura and the parietal pleura cannot be seen. A pleural effusion infiltrates the space between these layers. Because the pleural effusion has a density similar to water, it can be seen on radiographs. Since the effusion has greater density than the rest of the lung, it gravitates towards the lower portions of the pleural cavity. The pleural effusion behaves according to basic fluid dynamics, conforming to the shape of pleural space, which is determined by the lung and chest wall. If the pleural space contains both air and fluid, then an air-fluid level that is horizontal will be present, instead of conforming to the lung space. Chest radiographs in the lateral decubitus position (with the patient lying on the side of the pleural effusion) are more sensitive and can detect as little as 50 mL of fluid. Between 250 to 600mL of fluid must be present |
1442_13 | before upright chest X-rays can detect a pleural effusion (e.g., blunted costophrenic angles). |
1442_14 | Chest computed tomography is more accurate for diagnosis and may be obtained to better characterize the presence, size, and characteristics of a pleural effusion. Lung ultrasound, nearly as accurate as CT and more accurate than chest X-ray, is increasingly being used at the point of care to diagnose pleural effusions, with the advantage that it is a safe, dynamic, and repeatable imaging modality. To increase diagnostic accuracy of detection of pleural effusion sonographically, markers such as boomerang and VIP signs can be utilized. |
1442_15 | Thoracentesis
Once a pleural effusion is diagnosed, its cause must be determined. Pleural fluid is drawn out of the pleural space in a process called thoracentesis, and it should be done in almost all patients who have pleural fluid that is at least 10 mm in thickness on CT, ultrasonography, or lateral decubitus X-ray and that is new or of uncertain etiology. In general, the only patients who do not require thoracentesis are those who have heart failure with symmetric pleural effusions and no chest pain or fever; in these patients, diuresis can be tried, and thoracentesis is avoided unless effusions persist for more than 3 days. In a thoracentesis, a needle is inserted through the back of the chest wall in the sixth, seventh, or eighth intercostal space on the midaxillary line, into the pleural space. The use of ultrasound to guide the procedure is now standard of care as it increases accuracy and decreases complications. After removal, the fluid may then be evaluated for: |
1442_16 | Chemical composition including protein, lactate dehydrogenase (LDH), albumin, amylase, pH, and glucose
Gram stain and culture to identify possible bacterial infections
White and red blood cell counts and differential white blood cell counts
Cytopathology to identify cancer cells, but may also identify some infective organisms
Other tests as suggested by the clinical situation – lipids, fungal culture, viral culture, tuberculosis cultures, lupus cell prep, specific immunoglobulins
Light's criteria
Definitions of the terms "transudate" and "exudate" are the source of much confusion. Briefly, transudate is produced through pressure filtration without capillary injury while exudate is "inflammatory fluid" leaking between cells. |
1442_17 | Transudative pleural effusions are defined as effusions that are caused by systemic factors that alter the pleural equilibrium, or Starling forces. The components of the Starling forces – hydrostatic pressure, permeability, and oncotic pressure (effective pressure due to the composition of the pleural fluid and blood) – are altered in many diseases, e.g., left ventricular failure, kidney failure, liver failure, and cirrhosis. Exudative pleural effusions, by contrast, are caused by alterations in local factors that influence the formation and absorption of pleural fluid (e.g., bacterial pneumonia, cancer, pulmonary embolism, and viral infection).
An accurate diagnosis of the cause of the effusion, transudate versus exudate, relies on a comparison of the chemistries in the pleural fluid to those in the blood, using Light's criteria. According to Light's criteria (Light, et al. 1972), a pleural effusion is likely exudative if at least one of the following exists: |
1442_18 | The ratio of pleural fluid protein to serum protein is greater than 0.5
The ratio of pleural fluid LDH and serum LDH is greater than 0.6
Pleural fluid LDH is greater than 0.6 or times the normal upper limit for serum. Different laboratories have different values for the upper limit of serum LDH, but examples include 200 and 300 IU/l. |
1442_19 | The sensitivity and specificity of Light's criteria for detection of exudates have been measured in many studies and are usually reported to be around 98% and 80%, respectively. This means that although Light's criteria are relatively accurate, twenty percent of patients that are identified by Light's criteria as having exudative pleural effusions actually have transudative pleural effusions. Therefore, if a patient identified by Light's criteria as having an exudative pleural effusion appears clinically to have a condition that usually produces transudative effusions, additional testing is needed. In such cases, albumin levels in blood and pleural fluid are measured. If the difference between the albumin level in the blood and the pleural fluid is greater than 1.2 g/dL (12 g/L), this suggests that the patient has a transudative pleural effusion. However, pleural fluid testing is not perfect, and the final decision about whether a fluid is a transudate or an exudate is based not on |
1442_20 | chemical analysis of the fluid, but an accurate diagnosis of the disease that produces the fluid.. |
1442_21 | The traditional definitions of transudate as a pleural effusion due to systemic factors and an exudate as a pleural effusion due to local factors have been used since 1940 or earlier (Light et al., 1972). Previous to Light's landmark study, which was based on work by Chandrasekhar, investigators unsuccessfully attempted to use other criteria, such as specific gravity, pH, and protein content of the fluid, to differentiate between transudates and exudates. Light's criteria are highly statistically sensitive for exudates (although not very statistically specific). More recent studies have examined other characteristics of pleural fluid that may help to determine whether the process producing the effusion is local (exudate) or systemic (transudate). The table above illustrates some of the results of these more recent studies. However, it should be borne in mind that Light's criteria are still the most widely used criteria. |
1442_22 | The Rational Clinical Examination Series review found that bilateral effusions, symmetric and asymmetric, are the most common distribution in heart failure (60% of effusions in heart failure will be bilateral). When there is asymmetry in heart failure-associated pleural effusions (either unilateral or one side larger than the other), the right side is usually more involved than the left.
The instruments pictured are accurately shaped, however, most hospitals now use safer disposable trocars. Because these are single use, they are always sharp and have a much smaller risk of cross patient contamination.
Treatment
Treatment depends on the underlying cause of the pleural effusion. |
1442_23 | Therapeutic aspiration may be sufficient; larger effusions may require insertion of an intercostal drain (either pigtail or surgical). When managing these chest tubes, it is important to make sure the chest tubes do not become occluded or clogged. A clogged chest tube in the setting of continued production of fluid will result in residual fluid left behind when the chest tube is removed. This fluid can lead to complications such as hypoxia due to lung collapse from the fluid, or fibrothorax if scarring occurs. Repeated effusions may require chemical (talc, bleomycin, tetracycline/doxycycline), or surgical pleurodesis, in which the two pleural surfaces are scarred to each other so that no fluid can accumulate between them. This is a surgical procedure that involves inserting a chest tube, then either mechanically abrading the pleura or inserting the chemicals to induce a scar. This requires the chest tube to stay in until the fluid drainage stops. This can take days to weeks and can |
1442_24 | require prolonged hospitalizations. If the chest tube becomes clogged, fluid will be left behind and the pleurodesis will fail. |
1442_25 | Pleurodesis fails in as many as 30% of cases. An alternative is to place a PleurX Pleural Catheter or Aspira Drainage Catheter. This is a 15Fr chest tube with a one-way valve. Each day the patient or caregivers connect it to a simple vacuum tube and remove from 600 to 1000 mL of fluid, and can be repeated daily. When not in use, the tube is capped. This allows patients to be outside the hospital. For patients with malignant pleural effusions, it allows them to continue chemotherapy if indicated. Generally, the tube is in for about 30 days, and then it is removed when space undergoes spontaneous pleurodesis.
Tubercular pleural effusion is one of the common extrapulmonary forms of tuberculosis. Treatment consists of antituberculosis treatment (ATT). The currently recommended ATT regime is two months of isoniazid, rifampicin, ethambutol and pyrazinamide followed by four months of isoniazid, rifampicin and ethambutol. |

1443_0 | Modern banking in India originated in the mid of 18th century. Among the first banks were the Bank of Hindustan, which was established in 1770 and liquidated in 1829–32; and the General Bank of India, established in 1786 but failed in 1791.
The largest and the oldest bank which is still in existence is the State Bank of India (SBI). It originated and started working as the Bank of Calcutta in mid-June 1806. In 1809, it was renamed as the Bank of Bengal. This was one of the three banks founded by a presidency government, the other two were the Bank of Bombay in 1840 and the Bank of Madras in 1843. The three banks were merged in 1921 to form the Imperial Bank of India, which upon India's independence, became the State Bank of India in 1955. For many years, the presidency banks had acted as quasi-central banks, as did their successors, until the Reserve Bank of India was established in 1935, under the Reserve Bank of India Act, 1934. |
1443_1 | In 1960, the State Banks of India was given control of eight state-associated banks under the State Bank of India (Subsidiary Banks) Act, 1959. These are now called its associate banks. In 1969, the Government of India nationalised 14 major private banks; one of the big banks was Bank of India. In 1980, 6 more private banks were nationalised. These nationalised banks are the majority of lenders in the Indian economy. They dominate the banking sector because of their large size and widespread networks. |
1443_2 | The Indian banking sector is broadly classified into scheduled and non-scheduled banks. The scheduled banks are those included under the 2nd Schedule of the Reserve Bank of India Act, 1934. The scheduled banks are further classified into: nationalised banks; State Bank of India and its associates; Regional Rural Banks (RRBs); foreign banks; and other Indian private sector banks. The SBI has merged its Associate banks into itself to create the largest Bank in India on 1 April 2017. With this merger SBI has a global ranking of 236 on Fortune 500 index. The term commercial banks refers to both scheduled and non-scheduled commercial banks regulated under the Banking Regulation Act, 1949. |
1443_3 | Generally the supply, product range and reach of banking in India is fairly mature-even though reach in rural India and to the poor still remains a challenge. The government has developed initiatives to address this through the State Bank of India expanding its branch network and through the National Bank for Agriculture and Rural Development (NABARD) with facilities like microfinance.
History
Ancient India
The Vedas are the ancient Indian texts mention the concept of usury, with the word kusidin translated as "usurer". The Sutras (700–100 BCE) and the Jatakas (600–400 BCE) also mention usury. Texts of this period also condemned usury: Vasishtha forbade Brahmin and Kshatriya varnas from participating in usury. By the 2nd century CE, usury became more acceptable. The Manusmriti considered usury an acceptable means of acquiring wealth or leading a livelihood. It also considered money lending above a certain rate and different ceiling rates for different castes a grave sin. |
1443_4 | The Jatakas, Dharmashastras and Kautilya also mention the existence of loan deeds, called rnapatra, rnapanna, or rnalekhaya.
Later during the Mauryan period (321–185 BCE), an instrument called adesha was in use, which was an order on a banker directing him to pay the sum on the note to a third person, which corresponds to the definition of a modern bill of exchange. The considerable use of these instruments has been recorded. In large towns, merchants also gave letters of credit to one another. |
1443_5 | Medieval Period
The use of loan deeds continued into the Mughal era and were called dastawez (in Urdu/Hindi). Two types of loans deeds have been recorded. The dastawez-e-indultalab was payable on demand and dastawez-e-miadi was payable after a stipulated time. The use of payment orders by royal treasuries, called barattes, have been also recorded. There are also records of Indian bankers using issuing bills of exchange on foreign countries. The evolution of hundis, a type of credit instrument, also occurred during this period and remain in use. |
1443_6 | Colonial era
During the period of British rule merchants established the Union Bank of Calcutta in 1829, first as a private joint stock association, then partnership. Its proprietors were the owners of the earlier Commercial Bank and the Calcutta Bank, who by mutual consent created Union Bank to replace these two banks. In 1840 it established an agency at Singapore, and closed the one at Mirzapore that it had opened in the previous year. Also in 1840 the Bank revealed that it had been the subject of a fraud by the bank's accountant. Union Bank was incorporated in 1845 but failed in 1848, having been insolvent for some time and having used new money from depositors to pay its dividends. |
1443_7 | The Allahabad Bank, established in 1865 and still functioning today, is the oldest Joint Stock bank in India, it was not the first though. That honour belongs to the Bank of Upper India, which was established in 1863 and survived until 1913, when it failed, with some of its assets and liabilities being transferred to the Alliance Bank of Simla.
Foreign banks too started to appear, particularly in Calcutta, in the 1860s. Grindlays Bank opened its first branch in Calcutta in 1864. The Comptoir d'Escompte de Paris opened a branch in Calcutta in 1860, and another in Bombay in 1862; branches followed in Madras and Pondicherry, then a French possession. HSBC established itself in Bengal in 1869. Calcutta was the most active trading port in India, mainly due to the trade of the British Empire, and so became a banking centre. |
1443_8 | The first entirely Indian joint stock bank was the Oudh Commercial Bank, established in 1881 in Faizabad. It failed in 1958. The next was the Punjab National Bank, established in Lahore in 1894, which has survived to the present and is now one of the largest banks in India.
Around the turn of the 20th century, the Indian economy was passing through a relative period of stability. Around five decades had elapsed since the Indian rebellion, and the social, industrial and other infrastructure had improved. Indians had established small banks, most of which served particular ethnic and religious communities. |
1443_9 | The presidency banks dominated banking in India but there were also some exchange banks and a number of Indian joint stock banks. All these banks operated in different segments of the economy. The exchange banks, mostly owned by Europeans, concentrated on financing foreign trade. Indian joint stock banks were generally under capitalised and lacked the experience and maturity to compete with the presidency and exchange banks. This segmentation let Lord Curzon to observe, "In respect of banking it seems we are behind the times. We are like some old fashioned sailing ship, divided by solid wooden bulkheads into separate and cumbersome compartments." |
1443_10 | The period between 1906 and 1911 saw the establishment of banks inspired by the Swadeshi movement. The Swadeshi movement inspired local businessmen and political figures to found banks of and for the Indian community. A number of banks established then have survived to the present such as Catholic Syrian Bank, The South Indian Bank, Bank of India, Corporation Bank, Indian Bank, Bank of Baroda, Canara Bank and Central Bank of India.
The fervour of Swadeshi movement led to the establishment of many private banks in Dakshina Kannada and Udupi district, which were unified earlier and known by the name South Canara (South Kanara) district. Four nationalised banks started in this district and also a leading private sector bank. Hence undivided Dakshina Kannada district is known as "Cradle of Indian Banking". |
1443_11 | The inaugural officeholder was the Britisher Sir Osborne Smith(1 April 1935), while C. D. Deshmukh(11 August 1943) was the first Indian governor. On December 12, 2018,Shaktikanta Das, who was the finance secretary with the Government of India, begins his journey as the new RBI Governor, taking charge from Urjit R Patel.
During the First World War (1914–1918) through the end of the Second World War (1939–1945), and two years thereafter until the independence of India were challenging for Indian banking. The years of the First World War were turbulent, and it took its toll with banks simply collapsing despite the Indian economy gaining indirect boost due to war-related economic activities. At least 94 banks in India failed between 1913 and 1918 as indicated in the following table: |
1443_12 | Post-Independence
During 1938–46, bank branch offices trebled to 3,469 and deposits quadrupled to 962 crore. Nevertheless, the partition of India in 1947 adversely impacted the economies of Punjab and West Bengal, paralysing banking activities for months. India's independence marked the end of a regime of the Laissez-faire for the Indian banking. The Government of India initiated measures to play an active role in the economic life of the nation, and the Industrial Policy Resolution adopted by the government in 1948 envisaged a mixed economy. This resulted in greater involvement of the state in different segments of the economy including banking and finance. The major steps to regulate banking included: |
1443_13 | The Reserve Bank of India, India's central banking authority, was established in April 1935, but was nationalized on 1 January 1949 under the terms of the Reserve Bank of India (Transfer to Public Ownership) Act, 1948 (RBI, 2005b).
In 1949, the Banking Regulation Act was enacted, which empowered the Reserve Bank of India (RBI) to regulate, control, and inspect the banks in India.
The Banking Regulation Act also provided that no new bank or branch of an existing bank could be opened without a license from the RBI, and no two banks could have common directors. |
1443_14 | Nationalisation in 1969
Despite the provisions, control and regulations of the Reserve Bank of India, banks in India except the State Bank of India (SBI), remain owned and operated by private persons. By the 1960s, the Indian banking industry had become an important tool to facilitate the development of the Indian economy. At the same time, it had emerged as a large employer, and a debate had ensued about the nationalization of the banking industry. Indira Gandhi, the then Prime Minister of India, expressed the intention of the Government of India in the annual conference of the All India Congress Meeting in a paper entitled Stray thoughts on Bank Nationalization. |
1443_15 | Thereafter, the Government of India issued the Banking Companies (Acquisition and Transfer of Undertakings) Ordinance, 1969 and nationalized the 14 largest commercial banks with effect from the midnight of 19 July 1969. These banks contained 85 percent of bank deposits in the country. Within two weeks of the issue of the ordinance, the Parliament passed the Banking Companies (Acquisition and Transfer of Undertaking) Bill, and it received presidential approval on 9 August 1969.
The following banks were nationalized in 1969:
Allahabad Bank (now Indian Bank)
Bank of Baroda
Bank of India
Bank of Maharashtra
Central Bank of India
Canara Bank
Dena Bank (now Bank of Baroda)
Indian Bank
Indian Overseas Bank
Punjab National Bank
Syndicate Bank (now Canara Bank)
UCO Bank
Union Bank of India
United Bank of India( now Punjab National Bank) |
1443_16 | Nationalisation in 1980
A second round of nationalizations of six more commercial banks followed in 1980. The stated reason for the nationalization was to give the government more control of credit delivery. With the second round of nationalizations, the Government of India controlled around 91% of the banking business of India.
The following banks were nationalized in 1980:
Punjab and Sind Bank
Vijaya Bank (Now Bank of Baroda)
Oriental Bank of Commerce (now Punjab National Bank)
Corporation Bank (now Union Bank of India)
Andhra Bank (now Union Bank of India)
New Bank of India (now Punjab National Bank)
Later on, in the year 1993, the government merged New Bank of India with Punjab National Bank. It was the only merger between nationalised banks and resulted in the reduction of the number of nationalised banks from 20 to 19. Until the 1990s, the nationalized banks grew at a pace of around 4%, closer to the average growth rate of the Indian economy. |
1443_17 | Liberalisation in the 1990s
In the early 1990s, the then government embarked on a policy of liberalisation, licensing a small number of private banks. These came to be known as New Generation tech-savvy banks, and included Global Trust Bank (the first of such new generation banks to be set up), which later amalgamated with Oriental Bank of Commerce, IndusInd Bank, UTI Bank (since renamed Axis Bank), ICICI Bank and HDFC Bank. This move – along with the rapid growth in the economy of India – revitalised the banking sector in India, which has seen rapid growth with strong contribution from all the three sectors of banks, namely, government banks, private banks and foreign banks. |
1443_18 | The next stage for the Indian banking has been set up, with proposed relaxation of norms for foreign direct investment. All foreign investors in banks may be given voting rights that could exceed the present cap of 10% at present. In 2019, Bandhan bank specifically, increased the foreign investment percentage limit to 49%. It has gone up to 74% with some restrictions.
The new policy shook the banking sector in India completely. Bankers, till this time, were used to the 4–6–4 method (borrow at 4%; lend at 6%; go home at 4) of functioning. The new wave ushered in a modern outlook and tech-savvy methods of working for traditional banks. All this led to the retail boom in India. People demanded more from their banks and received more.
PSB Amalgamations in the 2000s and 2010s
SBI
SBI merged with its associate bank State Bank of Saurashtra in 2008 and State Bank of Indore in 2009. |
1443_19 | Following a merger process, the merger of the 5 remaining associate banks, (viz. State Bank of Bikaner and Jaipur, State Bank of Hyderabad, State Bank of Mysore, State Bank of Patiala, State Bank of Travancore); and the Bharatiya Mahila Bank) with the SBI was given an in-principle approval by the Union Cabinet on 15 June 2016. This came a month after the SBI board had, on 17 May 2016, cleared a proposal to merge its five associate banks and Bharatiya Mahila Bank with itself.
On 15 February 2017, the Union Cabinet approved the merger of five associate banks with SBI. An analyst foresaw an initial negative impact as a result of different pension liability provisions and accounting policies for bad loans. The merger went into effect from 1 April 2017. |
1443_20 | BOB
On 17 September 2018, the Government of India proposed the amalgamation of Dena Bank and Vijaya Bank with erstwhile Bank of Baroda, pending (namesake) approval from the boards of the three banks. The Union Cabinet and the boards of the banks approved with the merger on 2 January 2019. Under the terms of the amalgamation, Dena Bank and Vijaya Bank shareholders received 110 and 402 equity shares of the Bank of Baroda, respectively, of face value 2 for every 1,000 shares they held. The amalgamation became effective from 1 April 2019. |
1443_21 | PNB
On 30 August 2019, Finance Minister announced that the Oriental Bank of Commerce and United Bank of India would be merged with Punjab National Bank, making PNB the second largest PSB after SBI with assets of and 11,437 branches. MD and CEO of UBI, Ashok Kumar Pradhan, stated that the merged entity would begin functioning from 1 April 2020. The Union Cabinet approved the merger on 4 March 2020. PNB announced that its board had approved the merger ratios the next day. Shareholders of OBC and UBI will receive 1,150 shares and 121 shares of Punjab National Bank, respectively, for every 1,000 shares they hold.
The merge came into effect since 1 April 2020. Post merger, Punjab National Bank has become the second largest public sector bank in India |
1443_22 | Canara Bank
On 30 August 2019, Finance Minister announced that Syndicate Bank would be merged with Canara Bank. The proposal would create the fourth largest PSB trailing SBI, PNB, BoB with assets of and 10,324 branches. The Board of Directors of Canara Bank approved the merger on 13 September 2019. The Union Cabinet approved the merger on 4 March 2020. Canara Bank assumed control over Syndicate Bank on 1 April 2020 with Syndicate Bank shareholders receiving 158 equity shares in the former for every 1,000 shares they hold.
Union Bank of India
On 30 August 2019, Finance Minister announced that Andhra Bank and Corporation Bank would be merged into Union Bank of India. The proposal would make Union Bank of India the fifth largest PSB with assets of and 9,609 branches. The Board of Directors of Andhra Bank approved the merger on 13 September. The Union Cabinet approved the merger on 4 March, and it was completed on 1 April 2020. |
1443_23 | Indian Bank
On 30 August 2019, Finance Minister announced that Allahabad Bank would be merged with Indian Bank. The proposal would create the seventh largest PSB in the country with assets of . The Union Cabinet approved the merger on 4 March 2020. Indian Bank assumed control of Allahabad Bank on 1 April 2020.
Rescue of private and co-operative banks (2020s)
Yes bank
In April 2020, RBI enlisted SBI to rescue the troubled lender Yes Bank, in the form of investment with assistance from other lenders viz., ICICI Bank, HDFC Bank and Kotak Mahindra Bank. SBI went on to own 48% share capital of Yes bank, which it later diluted to 30% in an FPO in the following months. |
1443_24 | Lakshmi Vilas Bank
In November 2020, RBI asked DBS Bank India Limited (DBIL) to take over the operations of the private sector bank Lakshmi Vilas Bank whose net worth has turned negative, following mismanagement and two failed merger attempts with NBFCs. DBS India's then having just 12 branches benefited by LVB's 559 branches. In a first of a kind move, Tier- II bond holders have been asked by RBI to write off their holdings in LVB.
Punjab and Maharashtra Co-operative Bank
In January 2022, RBI asked Unity Small Finance Bank Limited (Unity SFB) to take over the operations of the private sector bank Punjab and Maharashtra Co-operative Bank (PMC), following mismanagement and one failed merger attempts with NBFC/SFBs. Unity SFB then was being created by Centrum Finance and payment provider BharatPe to absorb the liabilities of the scam hit bank. In a first of a kind move, RBI allowed an established cooperative bank to merge into a then being created SFB. |
1443_25 | Regional Rural banks revamp
With a new policy effected in late 2010, the RRBs which served a smaller locality spanning a few districts, were merged into a state level entity following the merger of nationalised banks and their equity in RRBs getting sequentially higher. This eliminated the existential competition and cooperation between RRB's and essentially making them a subsidiary bank of the promoter nationalised bank with state equity.
Current period
Changed no of nationalised bank
[There has no exact data available now]
The Indian banking sector is broadly classified into scheduled banks and non-scheduled banks. All banks included in the Second Schedule to the Reserve Bank of India Act, 1934 are Scheduled Banks. These banks comprise Scheduled Commercial Banks and Scheduled Co-operative Banks. Scheduled Co-operative Banks consist of Scheduled State Co-operative Banks and Scheduled Urban Cooperative Banks. |
1443_26 | In the bank group-wise classification, IDBI Bank Ltd. is included in the category of other public sector bank.
With the growth in the Indian economy expected to be strong for quite some time-especially in its services sector-the demand for banking services, especially retail banking, mortgages and investment services are expected to be strong. One may also expect M&As, takeovers, and asset sales.
In March 2006, the Reserve Bank of India allowed Warburg Pincus to increase its stake in Kotak Mahindra Bank (a private sector bank) to 10%. This was the first time an investor was allowed to hold more than 5% in a private sector bank since the RBI announced norms in 2005 that any stake exceeding 5% in the private sector banks would need to be vetted by them. |
1443_27 | In recent years critics have charged that the non-government owned banks are too aggressive in their loan recovery efforts in connection with housing, vehicle and personal loans. There are press reports that the banks' loan recovery efforts have driven defaulting borrowers to suicide.
By 2013 the Indian Banking Industry employed 1,175,149 employees and had a total of 109,811 branches in India and 171 branches abroad and manages an aggregate deposit of and bank credit of . The net profit of the banks operating in India was against a turnover of for the financial year 2012–13. |
1443_28 | Pradhan Mantri Jan Dhan Yojana (, ) is a scheme for comprehensive financial inclusion launched by the Prime Minister of India, Narendra Modi, in 2014. Run by Department of Financial Services, Ministry of Finance, on the inauguration day, 1.5 Crore (15 million) bank accounts were opened under this scheme. By 15 July 2015, 16.92 crore accounts were opened, with around were deposited under the scheme, which also has an option for opening new bank accounts with zero balance.
Payment Bank |
1443_29 | Payments bank is a new model of banks conceptualized by the Reserve Bank of India (RBI). These banks can accept a restricted deposit, which is currently limited to ₹2 lakh per customer. These banks may not issue loans or credit cards, but may offer both current and savings accounts. Payments banks may issue ATM and debit cards, and offer net-banking and mobile-banking. The draft guidelines for licensing of payments banks in the private sector were formulated and released for public comments on July 17, 2014. The banks will be licensed as payments banks under Section 22 of the Banking Regulation Act, 1949, and will be registered as public limited company under the Companies Act, 2013.
Small finance banks |
1443_30 | To further the objective of financial inclusion, the RBI granted approval in 2016 to ten entities to set up small finance banks. Since then, all ten have received the necessary licenses. A small finance bank is a niche type of bank to cater to the needs of people who traditionally have not used scheduled banks. Each of these banks is to open at least 25% of its branches in areas that do not have any other bank branches (unbanked regions). A small finance bank should hold 75% of its net credits in loans to firms in priority sector lending, and 50% of the loans in its portfolio must be less than lakh (US$,000).
Banking codes and standards
The Banking Codes and standards Board of India is an independent and autonomous banking industry body that monitors banks in India.To improve the quality of banking services in India S S Tarapore (former deputy governor of RBI) had the idea to form this committee. |
1443_31 | Adoption of banking technology
Information Technology has had a great impact on the Indian banking system. The use of computers led to the introduction of online banking in India. The use of computers in the banking sector increased many fold after the economic liberalisation of 1991 as the country's banking sector has been exposed to the world's market. Indian banks were finding it difficult to compete with the international banks in customer service without the use of information technology. |
1443_32 | The RBI set up a number of committees to define and co-ordinate banking technology. These have included:
In 1984 was formed the Committee on Mechanisation in the Banking Industry (1984) whose chairman was Dr. C Rangarajan, Deputy Governor, Reserve Bank of India. The major recommendations of this committee were introducing MICR technology in all the banks in the metropolises in India. This provided for the use of standardised cheque forms and encoders. |
1443_33 | In 1988, the RBI set up the Committee on Computerisation in Banks (1988) headed by Dr. C Rangarajan. It emphasised that settlement operation must be computerised in the clearing houses of RBI in Bhubaneshwar, Guwahati, Jaipur, Patna and Thiruvananthapuram.

1444_0 | Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature. As RTD elements are fragile, they are often housed in protective probes.
RTDs, which have higher accuracy and repeatability, are slowly replacing thermocouples in industrial applications below 600 °C. |
