The results of temperature measurements per-formed in a borehole drilled on Surtsey in 1979 are presented. These results are used as the basis for a discussion of the thermal condition of Surts-ey. The hypothesis that intrusions rather than pillow lavas are responsible for the excess heat content

This paper describes a novel approach to monitoring the condition of small permanent-magnet synchronous motors (PMSM) operating under thermal stress. The approach begins with the estimation of temperature-dependent motor parameters from measurements of line voltages and currents. The parameters

ABSTRACT: Ground temperature variations have been analysed to the depth of 160 cm, with respect to meteorological elements and short−wave radiation balance. The database of the ground temperature covers a thirteen month−long period (May 1992 – June 1993), which in− cluded both the seasons of complete freezing of the ground and thaw. Special attention has been given to the development of perennial permafrost and its spatial distribution. In summer, the depth of thawing ground varied in different types of ground — at the Polish Polar Station, this was ca. 130 cm. The ground froze completely in the first week of October. Its thawing started in June. The snow cover restrained heat penetration in the ground, which hindered the ground thawing process. Cross−correlation shows a significant influence of the radiation bal− ance (K*) on the values of near−surface ground temperatures (r2 = 0.62 for summer).

A large number of deaths from accidents at home have still been observed in Japan, and about two-thirds ofthe victims are elderly people (1). Among the causes of accidents, death by drowning is the greatest in number, and those are found in bathrooms in the winter seasons (2). It might be due to insufficient

BOLD contrast adds an additional feature to magnetic resonance imaging and complements other techniques that are attempting to provide positron emission tomographylike measurements related

Weibel electromagnetic instability has been studied analytically in relativistic plasma with high parallel temperature, where | = ( 2 / ‖ )(1 +̂2 ⊥ / 2 2 ) 1/2 | ≪ 1 and while the collision effects of electron-ion scattering have also been considered. According to these conditions, an analytical

Beef cattle includes all animals of the genus Bos and their close relatives that are raised primarily for meat production. Bos animals that are utilized for milk are covered in Chapter 7: Dairy Cattle. As ruminants, beef cattle are capable of utilizing a wide range of feedstuffs and consequently are maintained in an array of situations ranging from extensive grazing to confined feedlot pens and intensive laboratory environments. Regardless of the housing system, basic needs for food, water, shelter, and comfort should be met.

, GLC is a challenging task due to the size and structure of modern circuits and insufficient controllability of a subset of gates in the circuit. We have developed a new approach for GLC that employs thermal conditioning to calculate the scaling factors of all the gates by solving a system of linear
