Because antimicrobial resistance in food-producing animals is a major public health concern, many countries have implemented antimicrobial monitoring systems at a national level. When designing a sampling scheme for antimicrobial resistance monitoring, it is necessary to consider both cost effectiveness and statistical plausibility. In this study, we examined how sampling scheme precision and s...

introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
Infiltration rate of water into the soil depends on the factors such as rock and litter cover, canopy cover, rainfall intensity, coarse material, land slope, soil texture and amount of initial soil moisture. The most important factors that are effective in the water infiltration rate of rangelands are livestock trampling and vegetation reduction due to the overgrazing. In present study, through...
the purpose of this article is to present the development of a wind farm, with a condition monitoring system (cms) based on control charts as the algorithm, centred on a new index, to prevent soil pollution by oil spills in wind farms. to this end, temperature sensors can be considered as one of the more significant sensors to be employed in this study, because the information obtained with reg...
Due to the harsh environmental conditions in arid and semi-arid area of country, it is essential to assess the factors affecting the vegetation in such areas. This study aimed to investigate the effect of some soil physicochemical properties (including texture, bulk density, moisture, organic matter, carbon, nitrogen, potassium, lime, sodium, electrical conductivity and pH) on Haloxylon persicu...
This paper focuses on the amount of diesel consumption as one of the non-renewable energy sources consumed by the agricultural machinery and water pumps in wheat and corn farms in Dire County,Kermanshah Province, Iran. The population of the study was determined by Bartlett table. Stratified random sampling method and census was used for the selection of respondents. The sample was composed of 2...
Rhamnus pallasii is one of important and valuable species in Khalkhal forest area.This study aimed to determine the relationship between vegetation properties of Rhamnus pallasii with soil and physiographic factors in this forest reserve. For this purpose, from 1030 to 2540 m.a.s.l, 48 sample plots of circular shape with an area of 500 m2, in three land forms (ridge, valley and slope) in four a...
ABSTRACT- To study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in Badjgah, Fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). In each pl...
