Dengue fever is a major health problem in Vietnam, but its incidence differs from province to province. To understand this at the local level, we assessed the effect of four weather components (humidity, rainfall, temperature and sunshine) on the number of dengue cases in nine provinces of Vietnam. Monthly data from 1999 to 2009 were analysed by time-series regression using negative binomial mo...
PURPOSE Our aim was to correlate the overall patient volume and the incidence of several ophthalmological diseases in our emergency department with weather data. PATIENTS AND METHODS For data analysis, we used our clinical data warehouse and weather data. We investigated the weekly overall patient volume and the average weekly incidence of all encoded diagnoses of "conjunctivitis", "foreign b...
1. introduction climate is a large system which is produced due to the relation and action between other large systems. if a change occurs in one of these systems, other systems will coordinate themselves with the change fast or slowly. the consequences of this coordination will impress the system that is starter of this change and an endless continuum of the links connects these systems togeth...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
one of the most main head in governments is to achieve the energy for their countries. as the fossil sources are at their ends and also they cause greenhouse emission and environment pollution, shifting to renewable sources of energy is an indispensable alternative for most countries. the sun is the most important renewable energy source. to assessment reachable solar radiation in mashhad from ...
Estimation of evapotranspiration is essential for planning, designing and managing irrigation and drainage schemes, as well as water resources management. In this research, artificial neural networks, neural network wavelet model, multivariate regression and Hargreaves' empirical method were used to estimate reference evapotranspiration in order to determine the best model in terms of efficienc...
now-a-days graphic design plays a major role in influencing culture, society, business, and customers, in such a way that one could look upon every individual as a potential customer. graphic designers seek to identify customers needs and find an intelligent solution for them. correct identification and understanding of those needs is the first step towards achieving ones goals. marketing knowh...
Assessing the Homogeneity of Temperature and Precipitation Data in Iran with Climatic Approach Extended Abstract: Qualitative evaluation and validation of atmospheric parameters such as precipitation and temperature are the most important condition for statistical analysis in climatic and hydrological researches. In addition, the meteorological and climatological data have a crucial role i...
Investigations on the population dynamics of aphid Aphis gossypii Glover Bt (G.Cot.Hy.8 BG II) and non-Bt (G.Cot.Hy.8) were carried out at Main Cotton Research Station, Navsari Agricultural University, Surat, Gujarat during Kharif, 2020-21. The incidence aphids initiated in first week July (27th SW) cotton hybrid second (28th continued till crop harvest January (2nd both hybrids. peak activity ...
introduction because of the vital role of water in human life, examining the phenomenon of climate change effects on drought severity and frequency is important for any area of interest. nowadays, climate researchers considers the effects of climate change and climate simulations by using the atmospheric-ocean general circulation models. to achieve the prediction of climatologically parameters,...
