The total fat content of the Farmed common carp studied was 13.2%, which is categorized as high fat fish. Considering the amount and type of fish fat, which is unsaturated and long-chain fats and are very vulnerable to the oxidation process, therefore, in order to maintain their quality, artificial or natural preservatives should be used and stored in cold conditions. In this article, common carp was filleted and immersed for 5 min in water extract extracted from mistletoe leaf (Viscum album L.) by percolation method as a natural antioxidant in proportions of 1, 2 and 4%. Then the extract was evaluated in terms of extraction efficiency, phenolic and flavonoid compounds and free radical inhibition (DPPH), and the quality of fillets stored in the refrigerator at time intervals of 0, 4, 8, 12, and 16 days was evaluated with the tests of peroxide values (PV), anisidine value (AV), thiobarbituric acid (TBA), free fatty acids (FFA) and TOTEX amount. The results of extraction efficiency, total phenolic compounds (TPC), flavonoid compounds (TFC), and DPPH were 5.23%, 62.4 mgGA/g E, 34.71 mg QE/g E, and 78.2%, respectively. Also, the values of PV, TBA, FFA, AV, and TOTEX value in the 4% extract treatment were reported as the best treatment on the 16th day of the experiment, 3.42 (meq g O2/Kg Fat), 1.55 (MDA/Kg Fat), 0.85 (OA%), 4.67 and 11.51, respectively. According to these results, mistletoe aqueous extract with a concentration of 4% can be used to delay fat oxidation in farmed common carp.

For this research, 240 pieces of sea carp fry (with an average weight of 5±1g) were transported in 4 different salinity treatments of 0, 1, 3 and 6 g/l in three replicates (in plastic bags) for one hour. In order to check the blood parameters of the baby fish at the end of the experiment, blood was taken from the samples by cutting the tail stem. According to the results of measuring some biochemical parameters of blood serum, the amount of total protein did not show a significant difference between different treatments (P>0.05), but the amount of glucose and cortisol showed a significant decrease in saline treatments compared to the control (P<0.05). The results of measuring liver enzymes in the amount of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase showed no significant difference between different treatments (P>0.05). The results of measuring some blood hematology factors also indicated no significant difference in the number of red and white blood cells, hematocrit percentage and hemoglobin level in the treatments. (P>0.05). In general, it can be said that Fewer stress indicators were observed in the transported fish treated with 3 grams of salt per liter.

Background: Hyperbilirubinemia is one of the most common problems in term newborns and the phototherapy is the most widespread treatment for lowering bilirubin concentration in neonates. The purpose of this study is to compare the effectiveness of conventional phototherapy, double phototherapy and intensive phototherapy in decreasing serum bilirubin. Methods: This interventional study was done on 60 neonates divided randomly in three groups. Infants in group 1 received conventional phototherapy, in group 2 double phototherapy and in group 3 intensive phototherapy. The criteria for inclusion in the study were a weight >2500 gr and serum bilirubin level ³18 mg/dl. Serum bilirubin level, rectal temperature and specific gravity of urine were evaluated 6 and 12 hours after phototherapy. The data were analyzed with SPSS and Anova soft wares. Findings: The mean total bilirubin level of single, double and intensive phototherapy groups at the beginning of therapy were 19.7±1.6, 20.3±2.4 and 21.1±2.0 mg/dl respectively, there was no significant difference between the values. After 12 hours of therapy the mean total bilirubin levels of single, double and intensive phototherapy group were 18.0±2.2, 15.7±2.3 and 16.8±2.5 mg/dl respectively. Serum bilirubin concentration decreased during phototherapy (p=0.000) and there were significant differences between three groups (p<0.014). Body temperature increased in double phototherapy group (p=0.001), but it was stable in other groups. There was no significant difference between the groups (p=0.6). And no significant difference of the mean value of urine specific gravity in the three groups was observed after 12 hours of phototherapy. Conclusion: Our study showed that intensive phototherapy is more effective than single and safer than double phototherapy in reduction of bilirubin in jaundiced newborns.

Using the growth rings of otolith, growth parameters of orange - spotted grouper (Epinephelus coioides) from Hormozgan were estimated. Samples were collected monthly from fish markets, landing centers and industrial trawlers. Out of 469 specimens (total sample), 329 fish were aged using their otolith sections. Von Bertalanffy growth parameters for this species were calculated as follows: Whole population: L∞ = 111.323 , K = 0 and t1 = -0.427Females: L∞ = 106.137, K = 0,177 and t1 = -0.45Males: L∞= 116.967, K = 0.107 and t1 = -4.659 Lower growth rate (K) of males with respect to females may be related to protogeny in this species. Higher L∞ obtained in present study with respect to alternative values obtained in Kuwait are related to ecological or inter-specific differences.Weight (W) - length (Tl.) relationship for the whole and sex separated population calculated as below shows relative isometric growth in orange - spotted grouper. Whole population: W = 6×10-6 Tl. 3.213Females: W = 6×l0-6 Tl.3.246Males: W = 2×10-5 Tl.3.006

In this paper, we have proposed a new iterative method for finding the solution of ordinary differential equations of the first order. In this method we have extended the idea of variational iteration method by changing the general Lagrange multiplier which is defined in the context of the variational iteration method. This causes the convergent rate of the method increased compared with the variational iteration method. To prevent consuming large amount of the CPU time and computer memory and to control requires significant amounts of computations, the Taylor expansion of the iterative functions in each iteration are applied. Finally to extend the convergence region of the truncated series, also the Pade approximants are used. Error analysis and convergence of the method are studied. Some examples are given to illustrate the performance and efficiency of the proposed method. For comparison, the results obtained by the our method and the variational iteration method are ‎presented.

Optimum utilization of groundwater water resources, in a sustainable manner using Qanats, has always been of interest in arid and semi-arid regions. On the other hand, the analysis of spatial information affecting the presence of groundwater water needs powerful analytical methods which is able to interpret non-linear relationships, internal relationship and hidden information between affecting layers. In this regard, the current research is planned with the aim of comparative evaluation of the spatial changes of groundwater potential using Frequency Ratio (FR) and Weight of Evidence (WoE) models in the Esfarayen county, North Khorasan province. The factors of elevation above sea level, slope aspect, slope degree, land use, geology, topographic wetness index (TWI), plan curvature, profile curvature, distance from the river, drainage density, stream power index (SPI), distance from faults and fault density were prepared as effective layers in ArcGIS platform. Based on FR and WoE models, the relationship of spatial maps and groundwater potential was determined. Evaluation of prepared maps was done using relative operating curve (ROC). Based on the results, the Frequency Ratio model with Area Unver the Curve (AUC) value equal to 84.4 percent showed better performance than WoE model in the study area. Also, geological factors, land use, elevation above sea level and distance from the river were selected as the most important factors affecting the groundwater potential based on the results of the employed models. In addition, 12.5%, 28.45%, 34.75%, 19.3%, and 5% of the study area are located in the classes with very low, low, medium, high, and very high potential of groundwater based on the FR model, respectively. The results of the present research can be used in decision-making related to water resources management and locating areas prone to groundwater extraction or adopting optimal aquifer management strategies in Esfarayen county.
