The variability of temperature and precipitation is regarded as one of the main characteristics of the climate.Precipitation and its results, especially results such as droughts, vary on different temporal and spatial scales. Thepurpose of this paper is to determine the frequency of the inter-annual variability of the driest month in north-westIran. In order to obtain the best results, we used ...

the aim of this research is the study of trends in annual precipitation changes in some selected stations located in the sefid rood basin, applying the man-kendall non-parametric technique. the method is one of the most frequently used non-parametric techniques for trend analysis of precipitation on an annual scale. six synoptic stations located in the sefid rood basin were selected for the ana...

HYPOTHESIS As opposed to the traditional dictated report, the use of a computer-based synoptic operative report will mandate that the surgical resident have a better understanding of all facets of the procedure. DESIGN A prospective study over a 10-month period. SETTING A 636-bed community teaching hospital. PATIENTS A total of 57 consecutive patients and 60 operative procedures for breas...

Sea-ice conditions and kinematics are studied in the Palmer Long-Term Ecological Research (PAL LTER) study region west of the Antarctic Peninsula. Remote sensing data from ERS-1 Synthetic Aperture Radar (SAR) and Scatterometer (EScat) and from DMSP SSM/I, are used to study the influence of synoptic weather systems on sea-ice characteristics during July-August 1992. Weather records from Palmer S...

This paper describes a new high-resolution multi-platform multi-sensor satellite rainfall product for Southern Africa covering the period 1993-2002. The Microwave Infra-Red Algorithm (MIRA) employed to generate the rainfall estimates combines high spatial and temporal resolution Meteosat infrared data with infrequent Special Sensor Microwave Imager (SSM/I) overpasses. A transfer function relati...

A scheduling algorithm for IEEE 802.15.3 based ad hoc networks is proposed. Building on the performance analysis of previous proposals, a new algorithm called FASA was designed to exploit the features of the 802.15.3 architecture so as to achieve higher performance, with better channel utilization, and lower induced overhead. During the analysis, several performance metrics are investigated. We...

BACKGROUND With the growing global population, it is becoming increasingly difficult to ignore the demands for food and energy. A major portion of the food and energy is produced via agriculture and livestock activities. The objectives of this research are to gather information regarding the demographic features of farmers, previous poisoning, and the extent of farmers' knowledge in the use of ...
