Humidity is one of important environmental parameters, which refers to the water vapor content in the air. As one of the fundamental abiotic factors, humidity determines an environment where animals and plants can thrive, also influences the human life. There are three items commonly used to describe humidity, which are absolute humidity (AH), relative humidity (RH) and specific humidity (SH) [...

OBJECTIVE Dengue viruses have rapidly spread in Southeast Asia, particularly in Pakistan, during the last few years, so the present study was undertaken to formulate a model for predicting dengue outbreak. METHODOLOGY A panel data using STRATA statistical software was employed to determine the effects of entomological indices, Per Man Hour Density (PMHD), Minimum Infection Rate (MIR) and sele...

accurate estimation of reference evapotranspiration plays a key role in water resources management and irrigation scheduling. the fao penman-monteith (f-p-m) is a reference method for calculation of evapotranspiration that needs temperature, humidity, wind speed and solar radiation. in many stations, it is not an easy task to measure the whole weather variables. thus, in this situation, one mus...

The effects of low and high relative humidity and of polyethylene glycol-induced root water stress on chlorophyll accumulation, on formation of the lamellar chlorophyll-protein complexes, and on the development of photosynthetic activity during chloroplast differentiation were examined. Low relative humidity or polyethylene glycol-induced root water stress (stress conditions) resulted in a 3 to...

The survival of toxigenic Pasteurella multocida in air and liquids was studied to identify possible risk factors in the etiology of atrophic rhinitis. In aerosols, at low relative humidity (28%), the viability of toxigenic P. multocida 5 min after aerosolization was at least 22% of its initial value. Viability at low relative humidity declined to 8% after 45 min. Viability at high relative humi...

in order reaching to occurate water regime under minimum tillage system and its effect on the physiological indices of 3 rice cultivars an experiment  was conducted as a split-plot design based on  randomized complete block with three replication in the year of 2006-2007 at research field of shavour station. treatment contains three water regimes with one day or check, two (i2) and three days (...

An idealized model of advection and condensation of water vapor is considered as a representation of processes influencing the humidity distribution along isentropic surfaces in the free troposphere. Results are presented for how the mean relative humidity distribution varies in response to changes in the distribution of saturation specific humidity and in the amplitude of a tropical moisture s...

BACKGROUND Women infected with human immunodeficiency virus (HIV) are at increased risk for the development of dysplastic genital lesions. Traditionally, markers of immunosuppression were predictive of the development of dysplasia. Recent advances in antiretroviral medications allow restoration of a once-depressed CD4+ cell count and suppression of HIV replication. In this new era, additional p...

Introduction: Since the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, disease has spread rapidly throughout world and became a traumatic stressor. Identification factors affecting makes it possible to prevent its further propagation save more people in similar situations. Environmental climatic parameters are among prevalence diseases. Determination environmen...
