Exposure to microgravity is known to alter genomic and proteomic expression and suppress immune cell activity. These changes may influence cancer development. Studying cancer cells in this environment, may help uncover novel therapeutic targets. SUNY Polytechnic Institute and SpacePharma, Inc. have teamed up to study the effect of microgravity on cancer cell migration. This will be achieved ...

At the 2006 Winter Olympics, the jump length difference between first and second place was only 5cm. This illustrates why ski jumpers are constantly tinkering with their posture in order to gain even the smallest of advantages. Experiments such as those shown in Figures 1 and 2 (b), conducted with ski jumpers in large-scale wind tunnels showed that even small changes in position can lead to ...

Lake Victoria is the largest tropical lake in the world and is very important for environment and economy in East Africa. The hydrodynamic processes in the shallow (40-80 m deep) water system are unique due to its location at the equator which makes Coriolis effects noticeable also for vertical transport. The limited river inflow, and the large surface area compared to its volume make Lake ...

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented study, two test methods for analyzing the flow and mixing of the liquid steel in the tundish were used. The ...

The blast furnace hearth drainage constitutes a major part of the blast furnace operation. Especially, keeping track of the iron and slag levels is crucial to adapt the tapping strategy. The operational target is usually not only to empty the blast furnace as far as possible but also to keep the slag below a critical level to prevent flooding of the tuyeres where the hot blast is injected into ...

Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, melting of ice and snow, and rise in sea level etc. (AGECC 2010, Council 2013, IPCC, 2014). Increase in the ...

A numerical simulation study, using COMSOL Multiphysics®, was carried out to examine the temperature and concentration fields in the dissolution process of silicon into germanium melt. This work utilized a simplified configuration which may be considered to be similar material configuration to that used in the Vertical Bridgman growth methods. The concentration profile for the SiGe sample ...

A frequency-domain finite element (FE) technique for computing the acoustic scattering from axially symmetric fluid-loaded structures subject to a nonsymmetric forcing field based on Ref. 1 is extended to poroelastic media and implemented in COMSOL Multiphysics® software. This method allows for the scattering body to consist of any number of acoustic, elastic, and poroelastic domains. The ...

Electrochemical flow cells have found widespread use in analytical chemistry due to their short response time, high sensitivity and selectivity. The geometrical flexibility and therefore, the ease of coupling the electrochemical to other experimental techniques has attracted considerable interest for applications in electrocatalytic research as well. Such coupling is far more cumbersome with the ...

With the current trend towards always more complexity associated to more functionalities in biotechnological systems, it is required to know with accuracy the pressure drop in the circuitry of microfluidic systems. In general, a full three-dimensional calculation is not tractable due to the limited capacity of the computers. However, computational models can help to produce pressure drop ...
