Achieving high quality wine grapes depends on the ability to maintain mild to moderate levels of water stress in the crop during the growing season. This study investigates the use of thermal imaging for monitoring water stress. Experiments were conducted on a wine-grape (Vitis vinifera cv. Merlot) vineyard in northern Israel. Irrigation treatments included mild, moderate, and severe stress. Th...

in this research the daily data of 69 climatic variables (wind direction, wind speed, dry temperature, wet temperature, maximum and minimum temperature, average daily temperature, precipitation, relative humidity, station level pressure, cloudiness, horizontal visibility, vapor pressure, …) of abumoosa synoptic station during the years 1362-1388 were studied. initially, a data base of variabl...

The catalytic wet air oxidation (CWAO) of cationic red GTL over the Fe2O3-CeO2-Bi2O3/γ-Al2O3 catalyst was investigated under mild operating conditions in a batch reactor. The catalyst was prepared by wet impregnation, and characterized by N2 adsorptiondesorption (BET measurement), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The effect of the reaction conditions (catalyst...

Article history: Received 20 October 2015 Received in revised form 18 December 2015 Accepted 21 December 2015 Available online 22 December 2015 We present a new chlorine-free dry etching process which was used to successfully etch indium antimonide grown on gallium arsenide substrates while keeping the substrate temperature below 150 °C. By use of a reflowed photoresist mask a sidewall with 60 ...

Acrylamide concentrations in prune products--baby strained prunes (range = 75-265 µg kg(-1)), baby apple/prune juice (33-61 µg kg(-1)), prune juice (186-916 µg kg(-1)) and prunes (58-332 µg kg(-1))--on the Canadian market were determined. The formation of acrylamide in a simulated plum juice was also investigated under 'drying conditions' in an open vessel at temperatures <100°C for 24 h and un...

Leaf size varies by over a 100,000-fold among species worldwide. Although 19th-century plant geographers noted that the wet tropics harbor plants with exceptionally large leaves, the latitudinal gradient of leaf size has not been well quantified nor the key climatic drivers convincingly identified. Here, we characterize worldwide patterns in leaf size. Large-leaved species predominate in wet, h...

Stochastic daily weather time-series models ("weather generators") are parameterized consistent with both local climate and probabilistic seasonal forecasts. Both single-station weather generators, and spatial networks of coherently operating weather generators are considered. Only a subset of parameters for individual station models (proportion of wet days, precipitation mean parameters on wet...

Responses of the African weaver ants (Oecophylla longinoda) to nest damages were studied in the field in Nigeria. During the wet season, the ants responded to nest damages almost unexceptionnally by a quick onset of nest-repairing behaviour. The latencies to the start of nest-repairing activities (LN) did not depend on the size of the damage, but they were significantly shorter during the night...

In recent years, the rapid development of industrialization and urbanization has caused serious environmental pollution, especially particulate pollution. As the "Earth's kidneys," wetland plays a significant role in improving the environmental quality and adjusting the climate. To study how wetlands work in this aspect, from the early autumn of 2014 to 2015, we implemented a study to measure t...
