Measurements of Momentum and Heat Transfer across the Air–Sea Interface

Heat transfer across the interface between nanoscale solids and gas.

When solid materials and devices scale down in size, heat transfer from the active region to the gas environment becomes increasingly significant. We show that the heat transfer coefficient across the solid-gas interface behaves very differently when the size of the solid is reduced to the nanoscale, such as that of a single nanowire. Unlike for macroscopic solids, the coefficient is strongly p...

a comparative pragmatic analysis of the speech act of “disagreement” across english and persian

the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...

Nonlocal momentum transfer in welcher Weg measurements

A ‘‘which-path’’ ~welcher Weg! measurement necessarily destroys the fringes in a double-slit interference experiment. We show that in all instances one may attribute this destruction to a disturbance of the particle’s momentum by an amount equal to at least p\/2d , where d is the slit separation, in accordance with the uncertainty principle. However, this momentum transfer need not be local; th...

Active thermography as a tool to investigate heat and gas transfer across the air- water interface

Gas and heat exchange between the ocean and the atmosphere are a key process in the earth system. Active thermography is a tool that can be used to estimate heat and gas transfer rates with unprecedented temporal and spatial resolution compared to other measurement techniques. In this paper recent technical progress of this method is described: a) a spatially more homogeneous heating of the wat...
