ence; these are separated by contact with terrestrial objects? little or not at all by the atmosphere. Now, solar heat differs from that produced by ordinary combustion in various respects, and especially in the fact that it permeates glass and certain substances, which effectually stop terrestrial heat; nevertheless, certain bodies appear to possess tlicf property of transmitting all kinds of ...

In this paper the steady state performance of a variable conductance heat pipe, which its working fluid consists of two components (R11+ R113) is modeled. The role of the liquid film momentum and axial normal stresses are considered by use of the mean property of mixture and the governing equations are solved by conventional numerical methods. The results of the present model have been compared...

In serum there are two classes of hexosaminidase. One of these is heat-labile and is inactive in children with Tay-Sachs disease. Serum from heterozygotes for Tay-Sachs disease has half the normal activity of the heat-labile enzyme. The heat-labile enzyme can be inactivated by heating serum diluted in buffer for 5 mm at 60 #{176}C. We have used this property to develop a reliable, fully automat...

Heat conduction in a ne scale mixture of two conductors is examined in the presence of a contact resistance between phases. The problem is studied rigorously in the context of periodic homogenization. Unlike the case of perfect heat transmission between phases, the temperature elds studied here may converge weakly in L to the homogenized temperature. The temperature gradients converge weakly as...

Negative specific heat is a dramatic phenomenon where processes decrease in temperature when adding energy. It has been observed in gravo-thermal collapse of globular clusters. We now report finding this phenomenon in bundles of nearly parallel, periodic, single-sign generalized vortex filaments in the electron magnetohydrodynamic model for the unbounded plane under strong magnetic confinement....

We establish the strong unique continuation property for differences of solutions to the Navier–Stokes system with Gevrey forcing. For this purpose, we provide Carlemantype inequalities with the same singular weight for the Laplacian and the heat operator.

fulani ecotype chickens (fec) and yoruba ecotype chickens (yec) are the two major types of indigenous chickens in nigeria. they subsist under traditional animal husbandry and are thus liable to indiscriminate mating and consequently to loss of genetic diversity. fulani ecotype chickens (fec) and yoruba ecotype chickens (yec) were investigated to determine genetic variation at transferrin locus ...

In this paper we obtain the conservation equations of momentum-energy a relativistic fluid in flat space-time. Three mechanisms for energy and momentum transferring are considered, which are: perfect fluid, stress viscosity heat transfer mechanisms. The effect magnetic field is ignored paper. Also, connection non-relativistic seen paper, so, can be modified with influences.The method deriving a...

We evaluated factors limiting lactating Mongolian gerbils (Meriones unguiculatus) at three temperatures (10, 21 and 30°C). Energy intake and daily energy expenditure (DEE) increased with decreased ambient temperature. At peak lactation (day 14 of lactation), energy intake increased from 148.7±5.7 kJ day(-1) at 30°C to 213.1±8.2 kJ day(-1) at 21°C and 248.7±12.3 kJ day(-1) at 10°C. DEE increased...

We establish the saddle point property of the focusing selfsimilar solution of a free boundary problem for the heat equation with free boundary conditions given by u = 0 and ∂u ∂ν = 1.
