				<dcterms:abstract><![CDATA[Experiments were carried out in a commercial orchard during 1994, 1995 and 1996 to determine the influence of chemical thinning on characterisics of fruit and alternate bearing of native olive (Olea europea L) cvs. Dezfoul and Fishomi at early fruitlet stage. In 1994, branch sprays of naphthalene acetic acid (100, 150 and 200 mg/l), naphthalene acetamide (200 and 300 mg/l) and urea (0.6 and 1.2%) were applied to limbs of Dezfoul and Fishomi when their fruitIets
diameters were 6.43 and 6.28 mm, respectively. In the first experiment (1994), treatments had no considerable effect on characteristics of the fruits and alternate bearing in both cultivars, possibly due to late spraying. In the second year, same trealtments were applied to limbs of' Dezfoul and Fishomi when their fruitlets diameters were 3.80 and 3.73 mm, respectively. NAA at 150 and 200 mg/l n Dezfoul and 100, 150 and 200 mg/l in Fishomi signjficantly induced fruit abscission, but NAD and urea had no effect on fruit abscission in both cultivars. NAA at 150 mg/l in Fishomi and 200 mgll in Dezfoul significantly increased fruit weight, length, diameter, volume, flesh weight and flesh to seed ratio. None of the treatments had significant effect on return bloom. In 1996, branch sprays of urea (1.2, 3 and 6%) and sevin (1200 and 2400 mg/l) had no considerable effect on abscission percent and characteristics of fruit in both cultivars.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Frequency studies are, essentially, an application of the theories of probability and are based on available records of flood experiences. Several methods of analysis, based on the mathematics of probabilities, have been proposed which, when applied to the same series of data, yield frequency curves which are in reasonable agreement throughout a useful range of probabilities. A widely used method for generalizing flood characteristics is to prepare a regional frequency curve in which discharge is expressed as a factor times the mean annual flood, or the median annual flood. To do this, a common period of record is chosen for all stations in the region and individual flood frequency curves prepared, then from this set of curves, for each of several return periods, the median of the individual station factors were determined. This analysis provides two curves: the first expresses the flood discharge time relation, showing variation of peak discharge, expressed as a ratio to the mean annual flood, with recurrence interval. The second relates the mean annual flood to the size of the drainage area. A frequency curve may be defined for any place in the region by use of these two curves. To estimate the mean annual flood for ungauaged points in a homogeneous region, a satisfactory relation may be used in which available mean annual flood values have been plotted against size of catchment area. Such a plot is commonly represented by a fairly straight line on log-log paper.
If the scatter is excessive the region may not be homogenous, or factors other than catchment area are significant.
In addition flood having any return periods is estimated by multiple regression based watershed characteristics such as size of catchment, annual precipitation, channel slope, shape factor, density drainage etc. As a final results, several models presented for estimating design
floods, also somes aspects were proposed for further investigations.]]></dcterms:abstract>

In this study, a mathematical model introduced in order to study the position of soil wetting front during irrigation by point emitters in homegenious soil in unsteady condition. The model solves governing differential equation of unsaturated flow in cylindrical coordinated system with ADI procedure. The proposed model
showes very good agreement with the actual laboratories data. Evaluation of mass balance of water inflow to soil and variation of soil moisture in soil profile indicated that there is five percent erorr in the computation which may be neglected in practical purposes.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Soil conservation service (SCS) adjusted the kostiakovs infiltration model by adding a constant coefficient, for improvement of estimation. The improved model has three constant parameters, which are difficult to calculate. So SCS has taken the third constant parameter as equal to 0.65-0.7 cm to simplify the estimation. This parameter varies in different soil and often outranges the SCS estimation. In this study the estimation of model parameters have been achieved by the combination of Least-Squares and Newton-Rophson numerical method. For four types of soils the infiltration parameters were calculated. Comparisons of the results of SCS and this study have shown that, the model with parameter estimated by the new method has better agreement with field
measurement than the SCS method.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Trapezoidal channels are frequently used in irrigation networks and other free surface water conveyance systems. The computation of the critical flow depth is one of the primary importance in the design process. It is usually determined by using design charts of iteration techniques. However, researchers have recently proposed formulas that directly provide approximate solutions. This paper presents an explicit equation for calculating critical flow depths in trapezoidal channels. The proposed equation is applicable to any trapezoidal channel dimensions and provides the highest accuracy among available methods.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[The effects of cutting subsidy on broiler production in Kerman province were investigated after privitization. In this regard a random sample of 32 poultry farms in Kerman were chosen and the farmers were interviewed. The unit- output - price profit function model was used to determine the supply and demand elasticity of broider products. The results show that the profit of poultry farms increased after the subsidy were cut. Thus a competitive market increased the productivity of the farms. The demand elasticity for poultry food with regard to its price is high. Most of the raw materials required by such farms are imported, therefore computed elasticity coefficient was useful for making decisions regarding the allotment of foreign exchange to poultry farm. As a results, the government should encourage poultry farmers rather than interfering with the industry.]]></dcterms:abstract>

Whereas, the male sex of the same, attained earlier maturity within 23.26 ± 2.21 days, having one larval with two nymphal stages only. The maximum 87% prey consumption was recorded during oviposition period of 44.60 ± 12.81 days with an average fecundity of 132 ± 40.60 eggs.
