this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...

evaluation of river discharges trends is very important for water resources management and design of irrigation and drainage networks. in this research, annual, seasonal and monthly trends of maroon river discharge were evaluated using the mann-kendall and sen’s slope estimator non-parametric tests and the regression analysis parametric test. for this purpose, river discharge data from five h...

in order to investigate the effects of boron, zinc and sulfur on yield and fatty acid composition of rapeseed(hyola 401 cultivar), an experiment was conducted in rasht province in 2011. a field experiment withcompletely randomized block design was performed with eight treatments in three replications.maximum grain yield (4157.6 kg ha-1) and grain oil (1770.2 kg ha-1) was obtained from s+b+zntre...

to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...

a methodology to regenerate whole plants of fig tree (ficus carica cv. jaami-e-kan) from apical meristem of greenhouse plantlets was developed. two meristematic explants size (0.2-0.4 and 0.5-0.7 mm), two kinds of culture media and three concentrations of 6-benzyladenine (0.5, 1 and 1.5 mgrl-1) were tested as a completely randomize design (crd) with a simple factorial arrangement for establishm...

vapor-phase methylation of toluene using methanol and its isopropylation with 2-propanol has been investigated ina down flow reactor under atmospheric conditions using n2 carrier over a series of surface modified andunmodified zsm-5 (si/al= 60-170) loaded with h3po4, differing in the external surface treatment of the zeolites.the feed molar ratios of toluene/methanol and toluene/2-propanol were...

transesterification, one of the most effective methods for ester synthesis, is usually conducted under acid or basicconditions. although quite a few methods have been reported for transesterification, they are not general as far asp-ketoesters are concerned. some of these methods used toxic, expensive reagents and in relatives large amount. inthis research, transesterification reaction six type...

a one-pot multicomponent reaction of aryl aldehydes, 2-amino benzimidazole and ethyl 2-mercaptoacetate is described as an efficient and environmentally method for the synthesis of  some  novel  ethyl  2-((1h-benzo[d]imidazol-2-ylamino)(aryl)methylthio)  acetates  in  the presence of nano-copper y zeolite (ncz) as a catalyst in ethanol at room temperature. after optimizing of reaction conditions...
