Climate can affect the geographic and seasonal patterns of vector-borne disease incidence such as West Nile Virus (WNV) infections. We explore the association between climatic factors and the occurrence of West Nile fever (WNF) or West Nile neuro-invasive disease (WNND) in humans in Northern Greece over the years 2010-2014. Time series over a period of 30 years (1979-2008) of climatic data of a...
Abstract Forecasting electrical energy demand and consumption is one of the important decision-making tools in distributing companies for making contracts scheduling and purchasing electrical energy. This paper studies load consumption modeling in Hamedan city province distribution network by applying ESN neural network. Weather forecasting data such as minimum day temperature, average day temp...
Aims & Backgrounds: The present study was conducted to determine and evaluate thermal comfort in Shahrood. The main goal is to identify the best times for outdoor tourism in this city based on climatic conditions. Methodology: This is a descriptive-analytical research. Two quantitative indices Olgyay and Effective Temperature (ET) And Bahmanpour et al., (2012) model were used to determine the s...
BACKGROUND We evaluated the different climatic factors in urban and rural areas that may affect the incidence of urolithiasis. Nationwide data on urolithiasis were acquired from Health Insurance Review and Assessment Service between 2009 and 2013. Information on age, gender, date of diagnosis, geographic region and daily weather data from all weather stations was collected. The data were groupe...
In this paper, a non-isothermal two-phase flow in the cathode gas diffusion layer (GDL) of PEM fuel cell is modeled. The governing equations including energy, mass and momentum conservation equations are solved by numerical methods. Also, the optimal values of the effective parameters such as the electrodes porosity, gas diffusion layer (GDL) thickness and inlet relative humidity are calculated...
in this paper, the effect of air relative humidity and capillary force on contact geometry of surfaces based on jkr model by atomic force microscopy was investigated in order to manipulate nano-particles. with transition from macro to nano-scale, the effect of surface forces becomes more significant in comparison with inertial force. because contact mechanics models are based on surface energy ...
BACKGROUND The role of relative humidity in the aerosol transmission of influenza was examined in a simulated examination room containing coughing and breathing manikins. METHODS Nebulized influenza was coughed into the examination room and Bioaerosol samplers collected size-fractionated aerosols (<1 µM, 1-4 µM, and >4 µM aerodynamic diameters) adjacent to the breathing manikin's mouth and al...
The study was carried out to find the seasonal abundance and impact of abiotic factors on major sucking pests brinjal. Brinjal variety BR-112 transplanted first fortnight July, 2020 at Research Farm Department Entomology, CCS Haryana Agricultural University, Hisar. results revealed that population whitefly adults nymphs, jassids, aphids red spider mite brinjal initiated in 28th 30th, 31st, 48th...
in order reaching to occurate water regime in the condition of minimum tillage and its effect on the yield and yield component physiological index of rice varieties, a experiment had carried out the agronomey year of 2006-2007 in the research field of shavour station. the experiment had carried out in split-plot design some randomized complete block with three replication that contains three wa...
