To boost economic growth in the long-term (i.e. when the economy has reached its steady state), it is necessary to employ family policy as this increases both the fertility rate and the time individuals spend accumulating human capital. The main result for economic growth theory is that steady state economic growth is not possible when population is ageing.

### Title: ['Population ageing and economic growth : education policy and family policy in a model of endogenous growth ; with 32 tables']
### Abstract:
['We review standard economic growth models concentrating on the relationship between population ageing and economic growth and develop a growth model with endogenous human capital and endogenous fertility. With this model we analyse the effects of education policy and family policy on economic growth. The main result for economic policy is that education policy boosts human capital and thus economic growth only in the short-term (i.e. during the transition phase towards the steady state). To boost economic growth in the long-term (i.e. when the economy has reached its steady state), it is necessary to employ family policy as this increases both the fertility rate and the time individuals spend accumulating human capital. The main result for economic growth theory is that steady state economic growth is not possible when population is ageing. A steady state growth is only possible, if the age structure of the population is constant.']

3A551310251.jsonld | ["Mechanisms of cell cycle arrest and apoptosis induction by sulforaphane and combinatorial effects of sulforaphane and 3,3'-Diindolylmethane on cancer cell growth inhibition"] | ["The chemopreventive isothiocyanate sulforaphane, which is derived from broccoli, was shown to induce a mitotic cell cycle arrest in the human colon cancer cell line 40-16. This arrest was followed by mitochondria-dependent apoptosis. Sulforaphane potently inhibited NF- B activation upstream of its nuclear translocation and decreased the expression of a series of anti-apoptotic, NF- B-dependent genes, which supposedly facilitated apoptosis induction. Transient exposure of 40-16 cells to sulforaphane for up to 6 h resulted in reversible G2/M cell cycle arrest and cytostatic growth inhibition, whereas a minimum continuous exposure time of 12 h was necessary for sulforaphane to irreversibly arrest cells in G2/M and subsequently induce apoptosis. Low concentrations of sulforaphane caused a transient decrease in cytoplasmic glutathione levels followed by glutathione induction after 24 h.

### Title: ["Mechanisms of cell cycle arrest and apoptosis induction by sulforaphane and combinatorial effects of sulforaphane and 3,3'-Diindolylmethane on cancer cell growth inhibition"]
### Abstract:
["The chemopreventive isothiocyanate sulforaphane, which is derived from broccoli, was shown to induce a mitotic cell cycle arrest in the human colon cancer cell line 40-16. This arrest was followed by mitochondria-dependent apoptosis. Sulforaphane potently inhibited NF- B activation upstream of its nuclear translocation and decreased the expression of a series of anti-apoptotic, NF- B-dependent genes, which supposedly facilitated apoptosis induction. Transient exposure of 40-16 cells to sulforaphane for up to 6 h resulted in reversible G2/M cell cycle arrest and cytostatic growth inhibition, whereas a minimum continuous exposure time of 12 h was necessary for sulforaphane to irreversibly arrest cells in G2/M and subsequently induce apoptosis. Low concentrations of sulforaphane caused a transient decrease in cytoplasmic glutathione levels followed by glutathione induction after 24 h. However, depletion of glutathione did not seem to play a role for sulforaphane-induced apoptosis. Combination effects of sulforaphane and 3,3'-diindolylmethane were investigated in terms of cell growth inhibition in the 40-16 cell line. Sulforaphane and 3,3'-diindolylmethane inhibited cell proliferation antagonistically at low concentrations, but synergistically at cytotoxic concentrations."]

This problem, in its abstract form as a graph problem, is known as Vertex Cover, where given a graph, we search for a minimum number of vertices to delete to get rid of all edges.

### Title: ['Algorithms and experiments for parameterized approaches to hard graph problems']
### Abstract:
['Many combinatorial problems that come up in the real world have been classified as NP-hard [Garey and Johnson 1979]. An example is the following task: After a series of experiments, certain pairs of experiments are found to have conflicting results. We therefore know that for each pair, at least one of the experiments was faulty. We now want to find the minimum number of experiments to discard such that there are no more conflicts. This problem, in its abstract form as a graph problem, is known as Vertex Cover, where given a graph, we search for a minimum number of vertices to delete to get rid of all edges. It is by now an established assumption that NP-hardness implies an inherent combinatorial explosion in the solution space that leads to running times growing exponentially with the input size. This means that large instances of NP-hard problems cannot always be solved efficiently to optimality.']

The flow model presented is capable of siraulating a steady flow or a propagating wave in ordor to calculate the flow field in the proximity of a structure. The solver is based on the Reyuold's averaged Navier-Stokes equations, whereas the closure of the set of equatious is achieved by means of the k-iii(SST) turbulence model.Using the shear stress at the bottom computed by the flow model, a sedimeut transport rate may be calculated and subsoquently inserted in the bottom evolution equation.

### Title: ['Numerical modelling of flow and wave induced scour around vertical circular piles']
### Abstract:
[["A three-dimensional flow model capable of Simulation flows with or without free surface was coupled with a model capable of siraulating Sediment transport and bottom evolution, and a model for analysing soil stability. The flow model presented is capable of siraulating a steady flow or a propagating wave in ordor to calculate the flow field in the proximity of a structure. The solver is based on the Reyuold's averaged Navier-Stokes equations, whereas the closure of the set of equatious is achieved by means of the k-iii(SST) turbulence model.Using the shear stress at the bottom computed by the flow model, a sedimeut transport rate may be calculated and subsoquently inserted in the bottom evolution equation. This leads to an intense Sediment transport and thus to scour. Steep slopes will lead to sliding sediment grains when the actual slope angle ex-ceeds the friction angle of the sediment. In Order to keep the bottom geometry in a reasonablc shape, an algorithm is used to simulate sliding Sediments. Adjustments for the inception of motion and the sediment transport rate at slopes improve the original equations in such a way that sand sliding is less intensive with regard to the number of iterations rquired, even though it is still necessary. The resulting scour geometry is therefore also characterized by this algorithm, which depends on one soil parameter.A more general model for determining slope stability was developed and coupled with the existing flow and sediment transport model. The bottom is idealised as a three-dimensional solid body and a fiuite element aualysis is carried out in order to calculate the erosion zones under given conditions. When determining the slope stability, this approach not only takes aecount of the friction angle but also several other soil parameters as well as the bottom geometry.The model described was used to simulate different laboratory experiments of flow and wave induced scour. A vertical cylinder and an abutmeut in steady flow conditions were considered as well as experiments with short waves (KC<6) and long waves (KC>6) to validate the model. Furthermore, a scour resulting from a wave spectrum was considered as test case for the numerical model.", "Ein dreidimensionales, numerisches Strömungsmodell wurde mit einem Sedimenttransport und einem Modell zur Analyse der Bodenstabilität gekoppelt.
