a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
We surveyed montane meadows in the northern Sierra Nevada and southern Cascades for two field seasons to compare commonly used aquatic and terrestrial-based assessments of meadow condition. We surveyed (1) fish, (2) reptiles, (3) amphibians, (4) aquatic macroinvertebrates, (5) stream geomorphology, (6) physical habitat, and (7) terrestrial vegetation in 79 meadows between the elevations of 1,00...

OBJECTIVE This study examined the role of marital quality in the physical health of mature adults. METHOD Participants were from the National Survey of Midlife Development in the United States aged 50+ years who were in their first marriage. Five dimensions of marital quality and four indicators of physical health were used. RESULTS Regression analyses indicated that marital quality indices...
Crop biomass is a critical variable for characterizing crop growth development, understanding dry matter partitioning, and predicting grain yield. Previous studies on the spectroscopic estimation of crop biomass focused on the use of various spectral indices based on chlorophyll absorption features and found that they often became saturated at high biomass levels. Given that crop biomass is com...
water is one of the most valuable natural resources in human societies which is demanded by different parts of the society, and as one of the main inputs of production in agriculture has a special role in the agricultural sustainable development. nowadays, the consumption of water is more than the supply, and its highest consumption is in agriculture. this study scrutinized the role of manageme...
