This paper describes results of a field measurement in which the feasibility low temperature heating and performance improvement by means convection enhancement around radiators were examined radiant with plastic multi-tubular an existing reinforced concrete house without thermal insulation. Radiant can make both room air temperatures MRTs 22〜25℃ PMVs 0 〜± 0.5 supply being 30〜36℃. Convection sm...

in this study, mathematical modeling of hot air-drying of thin-layer papaya (carica papaya l.) slices with 5±1 mm thickness pretreated in osmotic solution (50% sucrose) was investigated. thin-layer drying was conducted under three different drying temperatures of 40, 50 and 60 °c at a constant air velocity of 0.9±0.1 m/s and absolute humidity of 0.6 ± 0.02 g of water/kg of dry air. it was found...

drying characteristics of quercus were determined experimentally as a function of temperature, air velocity, and variety (quercus persica and quercus libani). in order to estimate and select a suitable drying curve, five different thin layer drying models were fitted to the experimental data. experiments were performed at the air temperatures of 50, 60 and 70°c. at each temperature level, two a...

There has been evidence of warming rate varying largely over space and between seasons. However, little has been done to evaluate the spatial and temporal variability of air temperature in the Tarim Basin, northwest China. In this study, we collected daily air temperature from 19 meteorological stations for the period of 1960-2012, and analyzed annual mean temperature (AMT), the annual minimum ...

This paper introduces CityComfortþ, a new method to simulate the spatial variation of the mean radiant temperature (Tmrt) in dense urban areas. This method derives the Tmrt by modeling five components of radiation fluxesddirect solar radiation, diffuse solar radiation, reflected solar radiation, long-wave radiation from the atmosphere, and long-wave radiation from urban surfacesdeach weighted b...

The Nightfire algorithm detects and characterizes sub-pixel hot sources using multispectral data collected globally, each night, by the Suomi National Polar Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS). The spectral bands utilized span visible, near-infrared (NIR), short-wave infrared (SWIR), and mid-wave infrared (MWIR). The primary detection band is in the SWIR, centere...

A pair of antagonistic thermoreceptive cells is associated with each of two peg-in-pit sensilla located on the antennal tip of Aedes aegypti. One, the warm cell, responds to rapid warming with a sudden increase in the rate of discharge. The other, a cold cell, responds to rapid cooling with a sudden increase in the discharge rate. When temperature changes are provided by oscillating changes in ...

Using data from the contiguous USA, the relationship between mean and standard deviation of daily air temperature was estimated on a monthly timescale from 1948 to 1997. In general, there is either an inverse relationship or a weak relationship between mean and standard deviation. For both daily maximum and daily minimum air temperature, the inverse relationship is spatially coherent for one-th...
