Introduction: The issue of the influence external factors such as meteorological conditions on dynamics coronavirus pandemic is extremely relevant, since understanding physical foundations any process helps predict its results in specific and, to a certain extent, manage it. Objective: In order assess effect relative humidity incidence COVID-19, we analyzed opinions international scientific com...

This paper presents a relative humidity predictions using feedforward artificial neural network (FFNN). Relative humidity values obtained from weather records for Malaysia are used in training the FFNNs. The prediction of the relative humidity is in terms of Sun shine ration and cloud cover. However, three statistical parameters, namely, mean absolute percentage error, MAPE, mean bias error, MB...

The paper deals with the relationship betweeen the water content of washed Serratia marcescens and the thermodynamic activity of water, a,, over the range 0 < a, < 1.0. Two overlapping types of measurement are used: osmotic water exchange and water-vapour sorption. The data are given in terms of the equation w = Bm-' where w is water content, m is external osmolality (actual or effective, depen...

Evaporation is linearly and inversely related to absolute humidity at 26 degrees to 27 degrees C. The relative rate of loss in desert reptiles, rodents, and anurans is about 1:10:40. The maximum rate of water loss is about 2.5 and 5 times the basal rate, respectively, in pocket mice and sand lizards. The ratio of loss from lung to loss from skin is about 84:16 in kangaroo rats and 70:30 in ratt...

OBJECTIVE To explore the spatial-temporal interaction effect within a Bayesian framework and to probe the ecological influential factors for tuberculosis. METHODS Six different statistical models containing parameters of time, space, spatial-temporal interaction and their combination were constructed based on a Bayesian framework. The optimum model was selected according to the deviance infor...

Seasonal variation in urinary stone presentation is well described in the literature. However, previous studies have some limitations. To explore overall cumulative exposure-response and the heterogeneity in the relationships between daily meteorological factors and urolithiasis incidence in 6 major Korean cities, we analyzed data on 687,833 urolithiasis patients from 2009 to 2013 for 6 large c...

In regions with intense solar radiation it is common the use of aluminated covers in greenhouses, with the aim of reducing the inside temperature. However, the use of these covers reduces photosynthetic active radiation (PAR) transmitted into the greenhouse. The objective of the present study was to evaluate the influence of different covers on microclimate in greenhouses cultivated with cherry...

The investigation on impact of abiotic factors incidence insect pests in rice was carried out during Kharif 2021. highest and lowest Rice Yellow Stem Borer recorded at vegetative stage the form dead heart 31st Standard Meteorological Weeks (SMW) 40th SMW it 16.48% 1.10%, respectively, whereas reproductive white ear 42nd 41th i.e., 18.12% 16.75%, respectively. leaf folder 36th (16.25%) 44th (1.3...

Temperature and humidity are essential parameters in monitoring the health of patients critical care. An optical fibre sensor has been developed for simultaneous measurement relative (RH) temperature at a single tip based on reflected intensity. Combining these measurements enables absolute values to be obtained. The is first modified with coating poly(allylamine hydrochloride) (PAH) / silica n...
