A világunkon végigvonuló koronavírus-járvány számos kihívással szembesíti az egészségügyben dolgozókat. A vírus cseppfertőzéssel terjed, és magas a virulenciája, ezért minden olyan beavatkozás, mely légúti aeroszolképződést generál, potenciálisan veszélyezteti az ellátásban részt vevők egészségét. A koronavírus-fertőzés súlyos formája progresszív légzési elégtelenséggel jár, melynek ellátásában a korai endotrachealis intubáció és invazív gépi lélegeztetés elengedhetetlen. Az intubáció során fokozott a légúti aeroszolképződés veszélye, így magas az ellátó személyzet fertőződésének veszélye. Az előzőeken túl ezen betegeknél relatíve gyakori a nehéz légútbiztosítás is. Cikkünk célja, hogy gyakorlatorientált áttekintést adjon a koronavírussal fertőzött betegek légútbiztosításának specialitásairól, különös tekintettel az infekciókontroll és a betegbiztonság szempontjaira.

Qualitative identification of Cu, Sn, Pb, Ni, and Fe in Cu-alloys is presented. The method involves anodic sampling of alloys, separation and identification by thin-layer chromatography (TLC). The powerful desktop-computer tool makes it easy to optimize ternary solvent mixtures. Optimization was performed graphically by means of R si≥1 as a selected separation criterion. Mobile phase composition for optimal separation was determined as MeOH−HCl−H2O (60:35:5, v/v). The method was applied to Persian helmet as real sample.

Abstract  

The enthalpies and temperatures of melting of RSi(CH3)3, R4Si, R3P, R3As, R3Sb, R3Bi, R2Te and R2Hg (R=C6F5) were obtained by scanning calorimetry measurements. The pressure of the saturated and unsaturated vapors of RSi(CH3)3, R2Si(CH3)2, R4Si, R3Ga, R3P, R3As, R3Sb, R3Bi, R2Te and R2Hg has been measured by the static method with a membrane-gauge manometer. It was established that all investigated substances proceeded to vapor as monomers. Equations approximating the dependences of saturated vapor pressures on temperature and the enthalpies and entropies of vaporization were obtained. Grafite films with silicon intercalated up to 25 at.% were grown by CVD using R4Si as a precursor. These films showed semiconductor properties in the temperature interval 80–300 K.
