The effects of wind protection on growth and total and marketahle yields of snap hean tPhaseolus vulgaris L.) planted at 2-week intervals through the 1994 and 1995 growing seasons were examined. Research was conducted under nonirrigated conditions at the Shelterhelt Research Area, Univ, of Nebraska Agricultural Research and Development Center (ARDC) near Mead. 'Strike' <white-seeded) and 'Rushm...

BACKGROUND Our aim was to design a valid and reliable consumer quality index (CQI) specifically suited to assess the experiences that homeless people, homeless youth, and abused women have with shelter and community care services. METHODS A pilot CQI questionnaire was constructed on the basis of literature study, focus group discussions with clients, concept mapping by clients and shelter wor...

Assessing environmental effects of shelter forests is primarily necessary for realizing their greatest protective benefits. The Three-North Shelter Forest Program (TNSFP), the largest ecological afforestation program in the world, has been operated for three decades in China but so far lacks comprehensive assessment of its environmental impacts. Horqin Sandy Land (HSL) in Northeast China is one...

The wind wave regime of Tallinn Bay, Gulf of Finland, is analysed with the use of a simplified method of long-term computations of wave fields based on a high-resolution nested WAM model and Kalbådagrund (1991–2000) wind data. The distributions of probabilities for wave heights, annual and seasonal mean wave heights, density of wave energy and its flux (wave power), and 1-year return wave heigh...

Pulsed Doppler lidar is the infrared equivalent of pulsed Doppler radar. Instead of raindrops, however, lidars reflect off naturally-occurring dust particles (aerosols). The aerosols have negligible fall velocities and so trace the wind field nearly perfectly. Up until the mid-1990’s, Doppler lidars were limited to research implementations and short-duration, human-in-the-loop deployment for a ...

In an emergency situation shelter space is crucial for people affected by natural hazards. Emergency planners in disaster relief and mass care can greatly benefit from a sound methodology that identifies suitable shelter areas and sites where shelter services need to be improved. A methodology to rank suitability of open spaces for contingency planning and placement of shelter in the immediate ...

The question of climate at high obliquity is raised in the context of both exoplanet studies (e.g. habitability) and paleoclimates studies (evidence for low-latitude glaciation during the Neoproterozoic and the ‘‘Snowball Earth’’ hypothesis). States of high obliquity, /, are distinctive in that, for / P 54!, the poles receive more solar radiation in the annual mean than the equator, opposite to...

purpose estimating wind chill index as one of the indexes effective in body comfort, specifically for athletes and tourists interested in winter sports. methods meteorology data including temperature and the percentage of relative humidity of 6 synoptic stations of chaharmahal-bakhtiyrai province, iran from 1990 to 2007 were extracted from iranian meteorology site. in order to calculate the val...

the occurrence of dust storms and their sources in the southern and central parts of iran during the period of 2002 to 2009 was investigated. for this purpose, the meteorological and synoptic data, data from the middle and upper atmosphere, and wind flow tracking model were used. dust storms and nddi were traced using satellite imagery from fasa, shiraz, and bushehr stations. analysis of the gr...

land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. the rate of thisphenomenon is high in developing countries such as iran. this research investigated desertification and mapping ofdesertification in abuzaydabad, near kashan, iran, with an emphasis on land criteria using an imdpa model.different studies have assessed land degradation or desertificat...
