• Background • Acid Rain & Cars • Acid Rain & Forests • Acid Rain & Health • Acid Rain & Water • Acid Rain in Europe • Acid Rain in US • Acid Rain Study The ecological effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and marshes. Acid rain flows to streams, lakes, and marshes after falling on forests, fields, buildings, and roads. Acid r...

Background: Homelessness, as a common phenomenon in all human societies, has many social, psychological, and physical consequences for the homeless and society as a whole. This study aimed to determine the role of psychological and social security in predicting depression among women living in homeless shelters of Tehran. Methods: It was a descriptive correlational study. The research populati...

Mosquitoes found hibernating in underground shelters were studied in western Bohemia, Czech Republic. Species collected included Culiseta alaskaensis, Cs. annulata, Cs. glaphyroptera, Culex spp., and Anopheles maculipennis s.l.. Culex spp. were the most common, followed by Cs. glaphyroptera and Cs. annulata with few records of Cs. alaskaensis and An. maculipennis s.l.. Culex spp. were found in ...

TOPIC This is the personal perspective of the author's experience during Hurricanes Katrina and Rita. As a member of a professional mental health volunteer organization, this chronicles 3 months' experience in the local shelters. PURPOSE Difficulties with organizational support and structure hampered the effectiveness and functioning of this volunteer organization in the shelters. To identify...

Detection of rain/no-rain condition on the ground is an important for application of radar rainfall algorithms. A radial basis function (RBF) neural network-based scheme for rain/no-rain determination on the ground using vertical profiles of radar data is described in this paper. Evaluation based on WSR-88D radar over central Florida indicates that rain/no-rain condition can be inferred fairly ...

Gravity ventilators rely simply on air buoyancy to extract air and are widely used to exhaust air contaminants and heat from workplaces using minimal energy. They are designed to maximize the exhaust flow rate, but the rain penetration sometimes causes malfunctioning. In this study, the characteristics of rain penetration through a ventilator were examined as a preliminary study to develop a ve...

Though warm rain from low-level liquid clouds contributes significantly to the global precipitation and water cycle, it has been missed or underestimated by satellite remote sensing techniques. IR techniques miss all warm rain because they rely on cloud top temperature. Over land, passive microwave techniques miss all warm rain because they rely on ice scattering at high frequency channel. Over...

Measurements of rain attenuation over an earth-space path at Kolkata (22°34' N, 88°29' E), India, have been carried out since June 2004 by receiving a Ku-band signal from the satellite NSS-6 (geostationary at 95 E). The instantaneous attenuations are estimated from the point rain rates measured with an optical raingauge and using the Simple Attenuation Model (SAM). The estimated values closely ...

A Z-R relation is derived using a data set which consists of nine rain events selected from Singapore’s drop size distribution. Rain events are separated into convective and stratiform types of rain using two methods: the Gamache-Houze method, a simple threshold technique, and the Atlas-Ulbrich method. In the Atlas-Ulbrich method, the variability of the rain integral parameters R, Z, Nw, D0 and...
