Global warming has become a major threat to life on the earth, and recognizing its impacts can definitely be useful in controlling mitigating adverse effects. In this study, time series variations air temperature indices (frost days, Tmin, Tmax, Tmean, Tminmin, Tmaxmax, Tsoil-min), De Martonne aridity index (IDM), total precipitation were investigated using long-term meteorological data (1960–2...

Coffee is the most traded commodity in world. In Tanzania, second largest traditional commodity. However, several climate change studies have predicted that coffee production will be reduced as a result of change. Therefore, study aimed to assess impact current on Tanzania’s Arabica and determine significant climatic variables, which influence respective regions. Global interpolated d...

The study of the thermal radio emission of the moon and planets began in 1946 with the detection of the thermal radiation of the moon at 1.25cm wavelength by Dicke and Beringer [1]. This was followed three years later by a comprehensive series of observations of the radiation from the moon at 1.25cm wavelength over three lunar cycles by Piddington and Minnett [2] showing that the thermal radiat...

Global minimum temperatures (TMIN) are increasing faster than maximum temperatures, but the ecological consequences of this are largely unexplored. Long-term data sets from the shortgrass steppe were used to identify correlations between TMIN and several vegetation variables. This ecosystem is potentially sensitive to increases in TMIN. Most notably, increased spring TMIN was correlated with de...

Climate change variables have rarely been analyzed specifically for the growing season of crops. In this study, changes in minimum (Tmin) and maximum temperature (Tmax), daily maximum saturated vapor pressure (VPsat) and estimated daily VPD weighted for transpiration (VPDtran) were examined at five locations in Iran over 40 years during the growing seasons of chickpea and maize. The results of ...

PURPOSE The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. METHODS The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40 +/- 13 yr) and 14 healthy control subjects (mean age: 40 +/- 13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After i...

Atmospheric reanalysis products offer high-resolution and long-term gridded datasets that can often be used as an alternative or a supplement to observational data. Although more accessible than typical data deemed fit for climate change studies, show biases resulting from assimilation approaches. Thus, thorough evaluation of the product over region metric study is critical. Here, we evaluate p...

magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
