Abstract. This study presents an updated evaluation of stratospheric ozone profile trends in the 60? S–60? N latitude range over 2000–2020 period using version Long-term Ozone Trends and Uncertainties Stratosphere (LOTUS) regression model that was used to evaluate such up 2016 for last WMO Assessment (2018). In addition derivation detailed as a function vertical coordinates, regressions are per...
The rate of nucleoside transport decreased profoundly in human promyelocytic leukemia HL-60 cells after myeloid differentiation was induced by 5-6 days of exposure to 0.8% N,N-dimethylformamide (DMF). The facilitated diffusion of 100 microM radiolabeled adenosine and 2'-deoxyadenosine, measured by rapid transport assays, decreased 10- to 20-fold. The transport of 2 microM coformycin or 2'-deoxy...
Density functional theory studies of the structural and electronic properties of nanoclusters (ZnO) n (n = 34, 60) in different geometric configurations were conducted. For each cluster, an optimization (relaxation) of structure geometry was performed, and the basic properties of the band structure were investigated. It was established that for the (ZnO)34 nanoclusters, the most stable are full...
