By far, the analysis of particles heat and mass transfer in open nanosystems is of noticeable importance both in theoretical and practical researches. Due to a slotted and cylindrical systems resort we have been able to carry out some essential experimental investigations as well as provide new theoretical computations. The distinctive feature of nanosystems gas particles transport research is ...

The numerical investigation of drop deformation and breakup under simple shear is a basis for theoretical studies of emulsification and mixing. A three-dimensional Couette flow without gravity is considered; the matrix liquid is bounded at the top and bottom by two parallel horizontal plates and the liquid drop is suspended there. The boundaries move horizontally, and generate a simple shear fl...

The type III secretion system (TTSS) of gram-negative bacteria is responsible for delivering bacterial proteins, termed effectors, from the bacterial cytosol directly into the interior of host cells. The TTSS is expressed predominantly by pathogenic bacteria and is usually used to introduce deleterious effectors into host cells. While biochemical activities of effectors vary widely, the TTSS ap...

Detailed self-consistent calculations have been performed of the electron transport and capture aspects of the dynamics of electrically pumped quantum cascade intersubband semiconductor lasers. Specific attention is given to the dependence of the characteristic carrier relaxation times on carrier temperature and density at different applied biases. We have found that the capture and intersubban...

We developed an intelligent geoinformation platform for transport process analysis. The paper describes a purpose and functions of the synthesized platform as well as its structure including components and tools. We used the intelligent transport geoinformation platform for solving problems of acquisition, storage, processing and analysis of objects, processes and phenomena of urban transport i...

plastic recycling is the process of recovering scrap or waste plastics and reprocessing thematerial into useful products that sometimes differ completely in form from their original state. an importantissue in plastic recovery and recycling is that plastic waste usually contains a variety of plastics that differ intheir physical and chemical properties. separation of recovered plastics into dis...

Electron-transfer cross-reactions between neutral molecules and their radical cations spanning a wide range of structural type and intrinsic reactivity have been analyzed using classical Marcus theory. The principal factor found to govern intrinsic reactivity is the inner-shell bond reorganization energy. The HOMO-LUMO overlap of alkyl groups on reacting molecules is generally sufficient to pro...

The radical anions of β-lactams, photogenerated in the presence of DABCO as an electron donor, undergo cycloreversion via N-C4 bond cleavage, back electron transfer and final C2-C3 bond cleavage, leading to olefins. The involved intermediates are 1,4-radical anions and 1,4-biradicals. The experimental observations are consistent with the results of DFT calculations.
