Development of methods of ensuring purity of air environment in production rooms are especially relevant in connection with the development of nanotechnologies as well as engineering chemistries, related to possible emissions of harmful and dangerous dust. The main aim of the research is searching for optimum ways of deposition of fine aerosols comparing electrostatic and ultrasonic deposition of particles. Objects of the research are fine aerosols and ways of their deposition. Methods: mathematical modeling, optical methods of measurement of distribution function of particles by the sizes and concentration of aerosol particles using the laser measuring system LID2M and the Malvern Spraytec analyzer. Results. The authors have carried out the theoretical analysis of sedimentation rates of particles of fine aerosols (diameter of particles ~1-20 Β΅m) in the presence of acoustic, electric field taking into account a drift in electric field, ultrasonic coagulation, and acoustic flows (Β«sound windΒ»). The key mechanisms of particles deposition depending on their size are defined that allows proposing the optimum ways of deposition of fine aerosols in each range of particle sizes. The mathematical model of acoustic coagulation is based on an integral form of the equation of Smolukhovsky. The paper introduces the results of the experimental study of the model aerosol (NaCl) particles deposition with the reference diameter of particles about 6 Β΅m by means of ultrasound and electrodeposition device. It is defined that application of these ways of deposition is essential (and it is approximately identical) and it accelerates considerably sedimentation of the model aerosol that corresponds to theoretical results. On the other hand, theoretical calculations predict that application of electrostatic way of deposition will be more effective in comparison with the ultrasonic one for aerosols with rather larger particles

    Due to copyright restrictions, the access to the full text of this article is only available via subscription.In this paper, we investigate the diversity-multiplexing tradeoff (DMT) performance of a coherent free-space optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our study builds on the recently introduced statistical model that characterizes the combined effects of turbulence-induced wavefront distortion and amplitude fluctuation in coherent receivers with phase compensation. Our results provide insight into performance mechanisms of coherent FSO systems and demonstrate significant performance gains that can be obtained through the deployment of multiple receive apertures and phase compensation techniques

    Hepatocyte nuclear factor-4Ξ± is a central transactivator of the mouse Ntcp gene

    Sodium taurocholate cotransporting polypeptide (Ntcp) is the major uptake system for conjugated bile acids. Deletions of hepatocyte nuclear factor (HNF)-1Ξ± and retinoid X receptor-Ξ±:retinoic acid receptor-Ξ± binding sites in the mouse 5β€²-flanking region corresponding to putatively central regulatory elements of rat Ntcp do not significantly reduce promoter activity. We hypothesized that HNF-4Ξ±, which is increasingly recognized as a central regulator of hepatocyte function, may directly transactivate mouse (mNtcp). A 1.1-kb 5β€²-upstream region including the mouse Ntcp promoter was cloned and compared with the rat promoter. In contrast to a moderate 3.5-fold activation of mNtcp by HNF-1Ξ±, HNF-4Ξ± cotransfection led to a robust 20-fold activation. Deletion analysis of mouse and rat Ntcp promoters mapped a conserved HNF-4Ξ± consensus site at βˆ’345/βˆ’326 and βˆ’335/βˆ’316 bp, respectively. p-475bpmNtcpLUC is not transactivated by HNF-1Ξ± but shows a 50-fold enhanced activity upon cotransfection with HNF-4Ξ±. Gel mobility shift assays demonstrated a complex of the HNF-4Ξ±-element formed with liver nuclear extracts that was blocked by an HNF-4Ξ± specific antibody. HNF-4Ξ± binding was confirmed by chromatin immunoprecipitation. Using Hepa 1–6 cells, HNF-4Ξ±-knockdown resulted in a significant 95% reduction in NTCP mRNA. In conclusion, mouse Ntcp is regulated by HNF-4Ξ± via a conserved distal cis-element independently of HNF-1Ξ±
