2022 - War in Ukraine: ophthalmology in a state of emergency

Sibylle Scholtz, Lee MacMorris, Achim Langenbucher

Abstract: Something no one believed would happen today: a war of aggression in the mid Europe. On February 24, 2022, we all learned better. Since then, Russia has been waging a brutal war against Ukraine and its people. Instead of submitting, Ukraine is fighting with all its might. Not only militarily, but also medically and scientif [...] Read more.

Investigation of water hammer in bending stainless steel pipe under gravity flow

Yujian Ping, Akoto Emmanuel, Huli Ren

Abstract: A water hammer experimental setup consisting of a 20m long pipe having 8 U-shaped 180¬0 bends is investigated for hydraulic transient. Experimental results are then compared to numerical results simulated by the Method of Characteristics (MOC) and the Wave Characteristic Method (WCM). It is found that one-phase flow one-di [...] Read more.

30.76%(42.73)%-New Limiting Highest Efficiencies obtained in the \mathbf{n}^+(\mathbf{p}^+)-\mathbf{p}(\mathbf{n})\ Crystalline GaAs Junction Solar Cells at T=300 K, Due to The Effects of Heavy (Low) Doping and Impurity Size

H. Van Cong, K. C. Ho-Huynh Thi, C. T. Huynh-Pivet, A. Pivet, P. Damien

Abstract: In the n^+(p^+)-p(n) crystalline GaAs-junction solar cells, by basing on a same treatment method, and for a same heavy (low) doping effect, as those given in our recent paper (RP) [1], but using now a new expression, obtained for the relative dielectric constant \varepsilon\left(r_{d\left(a\right)}\right), determined exactl [...] Read more.

Trends in Prevalence of Hipercholesterolemia Among Catalan Adults 2001-2018 (Osona–Barcelona)

Joan Deniel-Rosanas, Jordi Prat-Quinzaños, Pere Roura-Poch, Maria-Àngels Casas-Capdevila, Victor Farré-Guerrero

Abstract: Background: The total cholesterol values of the Spanish population are high. The Preventive Activities Programs developed are not being sufficiently effective in improving population cholesterolemia. The involvement of other elements of society (education, the media, the food industry, etc.) may be essential in con [...] Read more.

To the justification of the Super-strong Anthropic Principle

Givishvili G.

Abstract: Empirical data in situ of recent years indicate that spacetime does not exist physically: they are not material - they do not have any of the characteristics inherent in material objects. At the same time, space-time is the most fundamental and universal mediator between all, without exception, material objects of Nature. I [...] Read more.

Feedback Functions in Problems of Nonlinear Programming

A.E. Umnov, E.A. Umnov

Abstract: The article considers a method for solving a nonlinear programming problem. This method uses special feedback functions that describe the relationship between direct variables and Lagrange multipliers. These relations are similar to the conditions of the Karush-Kuhn-Tucker theorem, but do not use inequalities in their notat [...] Read more.
