the most precise and simple method of evaporation measurement is application of pans in which class a pan is used in iran. in contrast, there are many empirical methods which are used for estimating the evapotraspiration. in this study, thornthwaite method was used due to the simplicity of its parameters and then we tried to use it for evaluating evapotranspiration by changing it's paramet...
a data file containing 607662 (317608) milk (open days) records belonging 294417 (177838) holstein cows that were calved from 1983 to 2008 was used. the bivariate repeatability model was used for data analyzing so that herd, calving year, calving month, days in milk (only for milk trait) and calving age for each parity, were assumed as fixed effects and additive genetics and permanent environme...
Recent results of searches for supersymmetric particles, Higgs bosons, and other new phenomena at LEP2 are summarized. These results are based on data and analyses from the four LEP experiments: ALEPH, DELPHI, L3, and OPAL. The data were collected during the summer and fall of 1996 with center-of-mass energies of 161 and 172 GeV. Supported by DOE Contract DE-FG0295-ER40896. c 1997 by Yibin Pan.
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
abstract the current research tried to examine the impact of multiple intelligence (mi) and its components on multiple choice (mc) and open ended (oe) reading comprehension tests. ninety six students of high school in grade four took part in this study. to collect data, participants completed multiple intelligence (mi) questionnaires along with a multiple choice (mc) and open ended (oe) forms ...
because of the scarcity of in situ measurements, estimation of soil temperature by other means is very indispensable, as for irrigation management and scheduling when in different field conditions. so far, many regression models have been developed for an estimation of soil temperature, using meteorological data under bare soil. throughout this study, the performance of coup simulation model an...
In this study, we used the ARIMA time series model, the fuzzy-neural inference network, multi-layer perceptron artificial neural network, and ARIMA-ANN, ARIMA-ANFIS hybrid models for the modeling and prediction of the daily electrical conductivity parameter of daily teleZang hydrometric station over the statistical period of 49 years. For this purpose, the daily data for the 1996-2004 period we...
limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...
the north bosque river (nbr) was included in the clean water act § 303(d) impaired list. the texas institute for applied environmental research used the soil water assessment tool (swat) to develop a phosphorus (p) total maximum daily load. swat was modified to dynamically change manure application rates based on simulated annual soil p, change areas receiving manure, alter manure quantities ea...
