Measuring system for determining the parameters required when designing cooled low-noise amplifiers

The error in measuring the magnetic components of the microwave field in a microstrip line is considered. Apparatus for measuring the parameters of the scattering matrix of field-effect transistors at low temperatures and under conditions that are as close as possible to the conditions under which they are used is described.

L'impact des sympt?mes somatiques dans l'évaluation de la dépression chez une population gériatrique.

Studied the relationship among age, physical health status, and psychic and somatic symptoms of depression among elderly adults. Human Ss: 318 male and female Canadian older adults (aged 65–102 yrs). Information on sociodemographic factors and health status was obtained using the Older American Research Scale, French version, by R. Lefran?ois et al (1988). A French version by P. Bourque and D. Beaudette (1982) of the Beck Depression Inventory was also used. The results were evaluated according to each S's sex, age, institutionalized residence status, and health status. Statistical tests were used. (English abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

CONSTRUCTION OF ADMISSIBLE OPERATION CONDITION DOMAIN FOR WELL-STIRRED REACTORS DURING THEIR DESIGN AND CONTROL STAGES

The work examines the problem of constructing an admissible operation condition domain for a well-stirred reactor which would satisfy restrictions in conversion, selectivity, heat removal and stability. The domain is very important and must be known during the reactor design and control stages because it yields visual information for analyzing the reactor operations and makes it possible to find the variation intervals of decision variables, necessary to calculate and optimize the reactor. Being known, the admissible operation condition domain makes it possible to estimate the limiting restrictions and to choose the necessary reserves. The domain has completely been studied analytically for chemical processes with arbitrary kinetics.

Transfer coefficients behind a system of parallel channels and in an annular channel of complex form

As a result of measuring the temperature (concentration) field behind the source, the transfer coefficients are determined for flow in a tube behind a system of parallel channelsZ/d = 50) and in an annual channel of complex cross section.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 55, No. 6, pp. 897-902, December, 1988.
