Simple transducer measures low heat-transfer rates

A simple transducer is used to measure low rates of convective and conductive heat transfer from a fluid to a cooled surface under steady-state conditions. Temperature drop is measured by two thermocouples imbedded in a rod of low thermal conductivity

Could languages of the same language families reflect a similar culture?

When learning two languages of the same language family, one will realize quickly that there are similarities. But how deep are language and culture related? For long time the hypothesis that languages are responsible for cultural development was held to be true, later the opposite was assumed, and today it is maybe somewhere in between. With the help of Geert Hofstede's dimensions, comparing cultures on a continuum of nonverbal aspects, a connection between linguistic and intercultural communication can be drawn, giving another view on the relation between languages and cultures --Culture,Language families,Intercultural Communication

Hydrogen-fueled engine

A hydrogen-oxygen fueled internal combustion engine is described, which utilizes an inert gas, such as argon, as a working fluid to increase the efficiency of the engine, eliminate pollution, and facilitate operation of a closed cycle energy system. In a system where sunlight or other intermittent energy source is available to separate hydrogen and oxygen from water, the oxygen and inert gas are taken into a diesel engine into which hydrogen is injected and ignited. The exhaust is cooled so that it contains only water and the inert gas. The inert gas in the exhaust is returned to the engine for use with fresh oxygen, while the water in the exhaust is returned to the intermittent energy source for reconversion to hydrogen and oxygen

When is an area law not an area law?

Entanglement entropy is typically proportional to area, but sometimes it acquires an additional logarithmic pre-factor. We offer some intuitive explanations for these facts.Comment: plainTeX, 12 pages, 3 figures. A more current version may be available at http://www.perimeterinstitute.ca/personal/rsorkin/some.papers
