Steps towards modern trends in district heating

District Heating in Buildings

This paper is published by Euroheat & Power. Our aim is to inform about district heating and cooling as efficient and environmentally benign energy solutions that make use of resources that otherwise would be wasted, delivering reliable and comfortable heating and cooling in return.

Modern trends in leprosy.

Modern Trends in Leprosy. SIR-I have read with much interest the above paper by Dr D. G. Jamison (Postgrad. med. J., 1969, 45, 408). On page 412 the author says: 'The Mycobacterium leprae has for generations been assumed to enter the body through the skin. Recently various other routes have been proposed (Weddell et al., 1963) such as the intestinal and respiratory tracts; and in babies, breast...

Modern Trends

Voluntary sterilization is the most prevalent method of fertility regulation, and its use is widespread in both developed and developing countries. The estimated number of couples controlling their fertility through sterilization has increased dramatically from 15 million in 197Oi to 100 million in 1980.” The country reporting the highest prevalence of use is the United States, where 31.3% of m...

Thermal Transients in District Heating Systems

Heat fluxes in a district heating pipeline systems need to be controlled on the scale from minutes to an hour to adjust to evolving demand. There are two principal ways to control the heat flux keep temperature fixed but adjust velocity of the carrier (typically water) or keep the velocity flow steady but then adjust temperature at the heat producing source (heat plant). We study the latter sce...
