The temperature field analysis method of steel tube reinforced columns under fire by finite element analysis software ABAQUS is proposed in this paper. The theoretical method is validated by tests, and the calculated results agree well with those of tests. On the basis of that, the influencing laws of temperature rising time; section perimeter; steel reinforcement ratio and sectional core area ...

Soil water content (SWC) is a crucial variable in the thermal infrared research and is the major control for land surface hydrological processes at the watershed scale. Estimating the surface SWC from remotely sensed data using the triangle method proposed by Price has been demonstrated in previous studies. In this study, a new soil moisture index (Temperature Rising Rate Vegetation Dryness Ind...

Rising atmospheric [CO2] is associated with increased air temperature, and this warming may drive many rare plant species to extinction. However, to date, studies on the interactive effects of rising [CO2] andwarming have focussed on just a few widely distributed plant species. Wollemi pine (Wollemia nobilisW.G.Jones, K.D.Hill, & J.M.Allen), formerly widespread in Australia, was reduced to a re...

We investigate non-homogeneous linear differential equations of the form x′′(t) + x′(t) − x (t) = p (t) where p (t) is either a polynomial or a factorial polynomial in t. We express the solution of these differential equations in terms of the coefficients of p (t), in the initial conditions, and in the solution of the corresponding homogeneous differential equation y′′(t) + y′(t) − y (t) = 0 wi...

In most developing coastal countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could impact the environmental carrying capacity of the fish stock. This study investigates the effect of ...

SCHMIDT-NIELSEN, K., E. C. CRAWFORD, JR., A. E. NEWSOME, K. S. RAWSON, AND H. T. HAMMEL. Metabolic rate of camels: effect of body temperature and dehydration. Am. J. Physiol. 2 I ~(2) : 341-346. 19670 -The effect on metabolic rate (oxygen consumption) of changes in body temperature and state of dehydration was studied in four camels. The data were subjected to multiple-regression analysis. The ...

As the planet warms, mountain snowpack is expected to melt progressively earlier each spring. However, analysis of measurements in western United States shows that change date when disappears not uniform: for 1?°C warming, 30 days some regions, whereas there almost no others. Here we present an idealized physical model simulates timing under changing temperature and use it show this observed di...

In the movement process of continuous bubbles, different liquid-flow state and initial temperature bubbles have important influence on bubble heat transfer. this study, flow transfer characteristics high in normal liquid are investigated. The rising studied by numerical simulation compared with experimental results for verification. show that shape, velocity affected position bubble. Because cl...
