East Asian summer monsoon delivers large abundances of very-short-lived organic chlorine substances to the lower stratosphere.

Deep convection in the Asian summer monsoon is a significant transport process for lifting pollutants from the planetary boundary layer to the tropopause level. This process enables efficient injection into the stratosphere of reactive species such as chlorinated very-short-lived substances (Cl-VSLSs) that deplete ozone. Past studies of convective transport associated with the Asian summer monsoon have focused mostly on the south Asian summer monsoon.

Pharmacy Students' Perceptions of Remote versus Face-to-Face Learning Experience.

During the COVID-19 pandemic, there was a large shift from face-to-face (FTF) to remote learning. Evaluating students' perceptions of remote learning provides educators with opportunity to inform their instructional methods. This study sought to evaluate pharmacy students' self-perceived (1) confidence, (2) preparedness, (3) satisfaction, and (4) motivation following remote vs.

Naval Special Warfare (NSW) crewmen demonstrate diminished cervical strength and range of motion compared to NSW students.

Background: Cumulative effects of high-impact vertical forces, like those experienced on an open-ocean mission, could be an injury concern for the cervical spine.

Objective: Compare cervical range of motion (ROM) and strength measures between students and NSW Crewmen and secondarily to compare these measures between students and Crewmen separated into three groups based on years of service.

Methods: A volunteer sample of 186 students (age: 22.

High-throughput heterogeneous catalytic science.

High-throughput experimentation in heterogeneous catalysis has recently experienced nearly exponential growth. Initial qualitative screening has evolved into quantitative high-throughput experimentation, characterization, and analysis. This allows high-throughput catalysis now to rise above simple screening to the level of fundamental understanding of reaction mechanisms, which will lead on a faster path to the Holy Grail of catalysis: rational catalyst design.

Noncontact dipole effects on channel permeation. III. Anomalous proton conductance effects in gramicidin.

Proton transport on water wires, of interest for many problems in membrane biology, is analyzed in side-chain analogs of gramicidin A channels. In symmetrical 0.1N HCl solutions, fluorination of channel Trp(11), Trp-(13), or Trp(15) side chains is found to inhibit proton transport, and replacement of one or more Trps with Phe enhances proton transport, the opposite of the effects on K(+) transport in lecithin bilayers.

Noncontact dipole effects on channel permeation. I. Experiments with (5F-indole)Trp13 gramicidin A channels.

Gramicidin A (gA), with four Trp residues per monomer, has an increased conductance compared to its Phe replacement analogs. When the dipole moment of the Trp13 side chain is increased by fluorination at indole position 5 (FgA), the conductance is expected to increase further. gA and FgA conductances to Na+, K+, and H+ were measured in planar diphytanoylphosphatidylcholine (DPhPC) or glycerylmonoolein (GMO) bilayers.

An improved method for in vitro susceptibility testing of Trichomonas vaginalis.

A protocol is presented for in vitro susceptibility testing of Trichomonas vaginalis. A 100 ml culture of the microorganisms is prepared for inoculation into antibiotic dilutions and controls by centrifugation, washing with 10 mM HEPES (pH 6.2) plus 1.
