This survey was conducted to quantify the effect of addition of Avizyme® multi enzyme to the body composition of western white shrimp (Litopenaeus vannamei)carrying the experiment based on initial average weight of 2.5±0.5 (gr). The experiment was conducted based on absolute casual program including 7 and 3 repetition for each attendants including a control attendants (free- canola, free Avizyme® -multi enzyme and 30% of fish meal) and six attendants at the level of 15,30,45 percent plant protein along with 0.5% Avizyme® multi enzyme and free-Avizyme® multi enzyme In the begging of the period, 525 shrimps were casually introduced in 21 plastic tanks of 50 liter each (25 shrimp in each tank). Shrimps were fed three times a day at 8, 14, 20 o'clock for about 8 weeks in a water with average temperature of 31.60 ± 0.60C0and water salinity of 41 ± 0.8 (ppm).In the begging of culturing process, 40 Shrimps were randomly selected and also at the end, from each repeat 10 shrimps were captured and after de-skinning and freezing they transferred to the laboratory for analyses of body. The results at the end 60 days of period showed that from humidity characteristic point of view and the shrimp body protein, no meaningful statistical differences were observed between the Control and testing attendants (P>0.05). But, From the protein characteristic aspect, fiber and body ash there were meaningful differences based on this, the lipid characteristic in testing attendants 1,2,3 with enzyme and similar attendants without enzyme and the control attendant, there were meaningful differences (P<0.05). The body ash characteristic between attendants 2 with 5 and 3with 6 in relation to control attendant was meaningful statistic differences.

An experimental study was conducted under dryland conditions to determine the influence of conventional and conservation tillage systems as well as seed rate on grain yield and yield components of a wheat cultivar in the central region of Iran. The experimental design was a randomized complete block with three tillage and four seed rate treatments with three replications. Tillage treatments comprised of conventional tillage (CT: moldboard+disk), reduced tillage (RT: chisel plow+disk), and no-till (NT: direct drilling with plow no-till drill), while the seed rate treatments were 80, 100, 120, and 140 kgha^-1. Average grain yield was 1804, 1754 and 1789 kgha^-1 for CT, RT and NT, respectively. The highest wheat yield was obtained from CT and NT treatments with seed rate of 100 kgha^-1 and the lowest yield was obtained in RT treatment with seed rate of 80 kgha^-1. The trend of wheat yield with seed rate (number of plants per hectare) was approximately similar to the parabolic response curve of grain yield versus number of plants per unit area which increases quickly to a maximum and slowly decreases at higher plant densities. To achieve the maximum yield of dryland wheat in central region of Iran, applying no-till system with seed rate of 100 kgha^-1 was recommended.

The study of radiation defects created in biomaterials, such as bones can be used in dating with importance to paleontology and archaeology. A preliminary attempt has been made to date the bone samples recently excavated from the archaeological site Gudnapur in Karnataka state, India. Each sample was divided into five sets which were given an artificial dose (AD) by using ? irradiation of 50 Gy, 300 Gy, 800 Gy, 1500 Gy and 3200 Gy. All the samples show similar EPR spectra having g-values 2.0026, 2.0025 and 2.0013 corresponding to orthorhombic CO2- and axial CO2- respectively. These signals have been used for the age estimation of the archaeological bone samples assuming the dose rate to be 6.8 mGy/a. The calculated ages of the samples are 36 ± 24 ka, 12 ± 87 ka and 19 ± 83 ka. These samples correspond to the upper stage of the Pleistocene epoch respectively and in good agreement with age predicted by archaeological Department. X-ray diffraction studies revealed the transformation of the mineral components partially into fluoroapatite form with addition of goethite, quartz phases and with preserved collagen remains. The aim was to establish their degree of preservation and possibilities of inferring the life conditions from them.

The combination of cystitis and emphysematous pyelonephritis is a serious but rare, the prognosis is related to renal damage. CT is the gold standard that allows the diagnosis and establishes a radiological classification with prognostic value. The therapeutic approach is based on The Early antibiotic treatment is systematic. Percutaneous drainage is the first step therapy in most cases,but should not delay a possible rescue nephrectomy. We report a case of emphysematous pyelonephritis associated with emphysematous cystitis in a 26 year old woman. Early diagnosis allowed conservative treatment with appropriate antibiotic therapy and urinary drainage catheter. The outcome was favorable.

The objective of the present study was to minimise the unwanted side effects of olanzapine (OZ) drug by kinetic control of drug release by entrapping OZ into gastro resistant, biodegradable waxes such as beeswax (BW), cetostearyl alcohol (CSA), spermaceti ( SP) and fat cetyl alcohol ( CA) microspheres using meltable emulsified dispersion cooling induced solidification technique utilizing a wetting agent. Solid, discrete, reproducible free flowing microspheres were obtained. The yield of the microspheres was up to 94.0%. Microspheres had smooth surfaces, with free flowing and good packing properties, indicating that the obtained angle of repose, % Carr’s index and tapped density values were well within the limit. More than 97.0% of the isolated spherical microspheres were in the particle size range of 312-330 µm as confirmed by scanning electron microscopy (SEM) photographs. The drug loaded in microspheres was found to be stable and compatible with waxes as confirmed by DSC and FTIR studies. The release of drug was controlled for more than 8 h. Intestinal drug release from microspheres was studied and compared with the release behaviour of commercially available formulation Olanex®. The release kinetics followed different transport mechanisms. The drug release performance was greatly affected by the materials used in microsphere preparations, which allows absorption in the intestinal tract.

The main objective of this study is to evaluate the correlated factors of landslide using certainty factor (CF) Model in Latyan catchment, north Tehran, Iran. At ?rst, a landslide inventory map was prepared using aerial photographs and the extensive ?eld survey. For this purpose, 208 landslides were mapped and out of which 145 (70 %) were randomly selected for building landslide susceptibility models, while the remaining 63 (30 %) were used for validating the models. In this study, 10 conditioning factors with their classes were evaluated. These factors including: slope; slope aspect; altitude; plan curvature; lithology; land use; distance from faults, rivers and roads and topographic wetness index (TWI). The validation of landslide susceptibility map was carried out using receiver operating characteristic (ROC) curve. Results shows that the slope class 20 ?–30 ?(0.10640), slope aspect northwest (0.53335), the altitude 1800 - 2000 m (0.40805), curvature concave (0.00788), geology Jd (0.86675), Land Use forest (0.94588), distance from faults 6500–9500 m (0.47110), distance from river 0–200 m (0.25148) and distance form roads 0–500 m (0.24822) have the highest CF values. The result of ROC curve also shows that the certainty factor model has high value of AUC (0.832) which indicates the model employed in this study reasonably good accuracy in predicting the landslide susceptibility of Latyan catchment.

The amino acid composition of the yolk and albumen of the egg of guinea fowl (Numida meleagris) was determined on a dry weight basis. The total essential amino acid ranged from (g/100 g crude protein, cp): 48.0-46.1 or from 49.3-49.2 % respectively of the total amino acid. The amino acid scores showed lysine ranged from 1.27-1.31 (on provisional essential amino acid scoring pattern) and 1.21-1.24 (on suggested requirement of the essential amino acid of a pre-school child). The predicted protein efficiency ratio was 3.74-2.59, the essential amino acid index range was 1.44-1.38 and the calculated isoelectric point range was 5.69-5.48. The correlation coefficient (rxy) was positive and significant at r = 0.05 for the amino acids, amino acid scores and the isoelectric point in the two samples.

With the newly improved ansaltz for the wave function and adopting the modified approximation scheme to evaluate the centrifugal term, we solve the Schrödinger equation with Woods-Saxon plus Rosen-Morse Potentials analytically, for arbitrary l-state. We also obtain the bound state energy spectrum and the unnormalized real and imaginary wave function.

In this paper, we present a counter-example for the stability of reciprocal type functional equation controlled by product of different powers in singular case.
