چکیده

Abstract. The lower-thermosphere–ionosphere (LTI) system consists of the upper atmosphere and lower part ionosphere as such comprises a complex coupled to both below space above. atmospheric LTI is dominated by laws continuum fluid dynamics chemistry, while plasma controlled electromagnetic forces driven magnetosphere, solar wind, well wind dynamo. hence domain many different physical processes. However, systematic in situ measurements within this region are severely lacking, although located only 80 200 km above surface our planet. This paper reviews current state art measuring LTI, either or several remote-sensing methods. We begin outlining open questions requiring high-quality measurements, before reviewing directly observable parameters their most important derivatives. motivation for review has arisen from recent retention Daedalus mission one among three competing candidates European Space Agency (ESA) Earth Explorer 10 Programme. intends cover that it can be used background scientific reference any targeting observations LTI.

Human 3-D tissue models in radiation biology: current status and future perspectives

In this review, we discuss the use of a variety of 3-D models (particularly 3-D skin, lung, breast and endothelial) in radiobiological research and highlight the differences in responses compared to 2-D culturing conditions (monolayers). We review the characteristics of existing 3-D models and aim to point out the substantial advantages 3-D cultures provide for modern radiobiology. In particula...

Measuring Time and other Spatio-Temporal Quantities

Ordinary clocks do not measure time in the common and Newtonian sense, and there is a similar problem for spatial measurements due to effects of motion and gravitation. Einstein’s theories of relativity are based on the denial of the possibility of the ‘absolute’ measurements that would be required. Nevertheless, here it is shown how such measurements can be performed. For this purpose, a “ligh...

Lipid apheresis techniques: current status in Germany

For long-term lipid apheresis therapy, several different technical systems have been developed which enable effective reduction of LDL cholesterol and other atherogenic lipoproteins, such as Lp(a), with sufficient selectivity and good clinical tolerance. Suitable techniques include whole blood adsorption with polyacrylamide and dextran sulfate cellulose, while primary plasma separation is used ...

Toxicity of Nanoparticles and an Overview of Current Experimental Models

Nanotechnology is a rapidly growing field having potential applications in many areas. Nanoparticles (NPs) have been studied for cell toxicity, immunotoxicity, and genotoxicity. Tetrazolium-based assays such as MTT, MTS, and WST-1 are used to determine cell viability. Cell inflammatory response induced by NPs is checked by measuring inflammatory biomarkers, such as IL-8, IL-6, and tumor necrosi...
