The paper presents the ionospheric effect on the power transmitted by satellite solar power station. Consequently, the Faraday rotation and losses due to ionospheric layer are calculated at 2.45GHz frequency. It is observed that the fluctuation in the Faraday rotation in day time is found to be the maximum as compared to the night hours and. Loss due to depolarization is found to have the maxim...

The genetic and clinical characteristics of 55 patients with schizophrenia and 138 control patients (with major psychiatric disorders), were studied in relation to the season of birth. The morbid risk (MR) of schizophrenia was significantly higher among relatives of the schizophrenic probands born in Spring than among those of the psychiatric controls born in the same season. The MR of schizoph...

Cucumber fruits (Cucumis sativus L., cv. Trópico F1) grown on perlite substrate and NFT (Nutrient Film Technique) were harvested during two seasons (winter and spring) to monitor the effects of climatic conditions and hydroponic growth systems on fruit quality at harvest. The best fruit quality at harvest, as measured by lightness and hue angle parameters, was obtained during the 3 weeks follow...

data. Although there were some differences they concluded: “Because onset and end dates of the growing season were averaged over the entire Tibetan Plateau, the temporal resolution of the data was deemed sufficiently high for detailed analysis.” So they tested whether winter warming might affect the plants’ chilling requirements in this cold, highaltitude environment. They determined the beginn...

Aim This study was conducted to determine the effect of seasonal variations on testosterone serum concentration, body weight, scrotal circumference, and some sperm parameters in rams living in a semi-arid region of eastern part of Algeria. Materials and Methods Blood samples were taken monthly from eight Ouled Djellal rams, aged between 3 and 4 years, in the Technical Institute of Breeding "I...

It is usually thought that a year consists of four seasons: spring, summer, autumn and winter. Taiwan basically follows the rule. Taiwan climate is mainly governed by monsoons. Therefore, the beginning of summer (winter) can be interpreted as the inward movement of summer (winter) monsoons. Considering the important role of mei-yu period, Chen (2000) pointed out that mei-yu should be added as a...

Twenty nonpregnant Angora does were used to determine seasonal effects on fleece traits, including fiber growth and follicle activity. Does grazed pastures and were supplemented with a 50% concentrate diet at a level near that required for BW maintenance. Clean fiber growth rate was greatest (p<0.05) among seasons in summer and lowest (p<0.05) in winter (1.13, 0.85, 0.98 and 1.20mg/cm(2) per da...

Today, it is widely used satellite imagery to monitor vegetation cover. The aim of this study is to analyses the leaf area in the period of 1395-1381 with the spatial resolution of a kilometer using the data of two remote sensing products of MODIS Terra and Aqua and seasonally. For this purpose, data were analyzed and statistical-mathematical compilation, coding and database creation were done ...

The 'season of birth' effect is one of the most consistently replicated associations in schizophrenia epidemiology. In contrast, the association between season of birth and development in the general population is relatively poorly understood. The aim of this study was to explore the impact of season of birth on various anthropometric and neurocognitive variables from birth to age seven in a la...

Polar organic compounds and elements were quantified in PM(10) aerosols collected in urban and rural areas of Baoji, an inland city of China, during winter and spring 2008. Concentrations of biomass burning markers and high molecular weight n-alkanoic acids (HMW, >C(22:0)) were heavily increased in winter. In contrast, sugars presented in higher levels in the spring, among which sucrose was the...
