INTRODUCTION The importance of lightning for climate studies is increasingly recognized. Thunderstorms are major players in the global redistribution of water substance, a key mediator of both short and long wavelength radiation. The cloud buoyancy that drives vertical motion in electrified convection is of the order of 1 C. Temperature perturbations of this order have appreciable local effects...

The main purpose of this paper is to determine the best performance time period of a system, consisting some DMUs, among some sequential time periods. This aim is satised by two proposed algorithms, the rst based on global Malmquist Productivity Index and the second is based on PPS frontiers.

Let $Gamma$ be a group, $Gamma'$ a subgroup of $Gamma$ with finite index and $M$ be a $Gamma$-module. We show that $M$ is cotorsion if and only if it is cotorsion as a $Gamma'$-module. Using this result, we prove that the global cotorsion dimensions of rings $ZGamma$ and $ZGamma'$ are equal.

introduction: chronic obstructive pulmonary disease (copd) secondary to sulfur mustard exposure, known as mustard lung, is an important late pulmonary complication. the bode (body mass index, obstruction, dyspnea, and exercise) index has been established as a valuable tool for determining the adverse consequences of copd. the aim of this study was to evaluate the role of the bode index in patie...

jeremy shiffman’s editorial appropriately calls on making all forms of power more apparent and accountable, notably productive power derived from expertise and claims to moral authority. this commentary argues that relationships based on productive power can be especially difficult to reveal in global health policy because of embedded notions about the nature of power and politics. yet, it is e...
