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...

Irrigating paddy fields is a very important process for plant growth. When the of irrigating rice carried out by means continuously flowing water and soil moisture value only based on estimates, there are many possibilities not to be measured where this causes plants take long time grow will rot or fail harvest if humidity too high. So final project was designed with title Humidity Control Syst...

A gill perfusion technique allowing control of flow and pOt in the ventral aorta and in the irrigating water is described. The procedure includes measurements of flow and pQi in the dorsal aorta and the inferior jugular vein. Pressure recordings were made in the ventral and dorsal aortas. Lowering the perfusion fluid po% and/or the irrigating water pOi increased the branchial vascular resistanc...

The wet bulb globe temperature index (WBGT) is a common method to assess the environmental contribution to heat stress as part of an occupational exposure assessment. The two purposes of this study were (1) to compare empirical relationships of some meteorological conditions to WBGT, and (2) to evaluate a smaller globe and alternative method to assess natural wet bulb using a relative humidity ...

Movable refuge chambers are a new kind of rescue device for underground mining, which is believed to have a potential positive impact on reducing the rate of fatalities. It is likely to be hot and humid inside a movable refuge chamber due to the metabolism of trapped miners, heat generated by equipment and heat transferred from outside. To investigate the heat stress experienced by miners trapp...

Α two-year field experiment was conducted in Varamin-Pishva Branch, Islamic Azad University, Iran to study the impact of drought stress and foliar application some hormones on safflower growth. The induced at three levels considered as main plots. Irrigating after 75% water depletion be normal irrigation (control), irrigating 60 45% depletion, defined mild severe stress, respectively. humic aci...

BACKGROUND AND OBJECTIVES Smear layer removal with EDTA from root canal walls allows greater cleaning and disinfection of root canals. However, because Er:YAG laser acts on the removal of the smear layer, the objective of investigation was to analyze in vitro the effect of Er:YAG laser on dentin root canal wall permeability after endodontic instrumentation and irrigation with water or sodium hy...

Certain inevitable physical factors in working environment can damage the workers in related fields. Sea sickness and white finger due to ship movement and vibration respectively are two examples in this regard. Humidity in working area can also bring discomfort of the workers in humid area. Cheese processing factories are such places where there is high humidity in the working space.Mental str...

INTRODUCTION Irrigating solutions are used for cleaning and removing dentinal debris, and the other remains from pulpal space during biomechanical preparation. Therefore, we evaluated the impact of various irrigating agents on root fracture at 5-minute time exposure. MATERIALS AND METHODS We sectioned 60 permanent maxillary premolars with fully formed root structures transversely maintaining ...
