Global warming has today turned to one of the most important environmental issues due tooveruse of fossil fuels, and it needs serious attention. Since the mid-1970s, an urgent needwas therefore felt around the world to reduce the use of energy for heating and cooling inbuildings. Using green covers, especially green facades, in appropriate environmentalconditions can be regarded as a method to ...

A low temperature fired Na2CaV4O12 ceramic was synthesized via a solid-state reaction route at range of 350–550 °C. The Thermal analysis confirmed the densification and melting to be 530 °C 580 °C, respectively. Dielectric properties together with electrical conductivity were characterized broad frequency range. super-low relative permittivity εr = 7.72 loss tangent tanδ 0.06 obtained 1 MHz roo...

In this paper we describe a novel long-term microhotplate temperature sensor calibration technique suitable for Built-In Self Test (BIST). The microhotplate thermal resistance (thermal efficiency) and the thermal voltage from an integrated platinum-rhodium thermocouple were calibrated against a freshly calibrated four-wire polysilicon microhotplate-heater temperature sensor (heater) that is not...

We measured the critical thermal maxima (CTMax) of tadpoles of Buergeria japonica inhabiting streams and geothermal hot springs. The CTMax of all B. japonica tadpoles was over 41 C, indicating that the tadpoles are heat-tolerant. At Rushan, we monitored the temporal and spatial distribution of tadpoles over a 24-h period in a 220 cm X 70 cm-plot that is fed by a geothermal hot spring. The therm...

Isokinetic assessment of elite squash, tennis and track athletes confirms the accepted ratio of 60 to 80 per cent hamstring to quadriceps when testing at 90 deg-sec-1 for peak strength (torque). However, significant variations occur at higher test speeds up to 300 deg.sec-1 with the hamstrings becoming more prominent especially (p less than 0.001) in the nonpreferred (NP) leg. There was no sign...
