The estimation of the amounts of precipitation in Qara-sou Drainage Basin is based on the observational data of 21 precipitation gauging stations in the area of the study. The correlation of above named elements with the data derived from the regional geographic factors indicates that using the regional data one can construct the final seasonal and annual precipitation models. The multiple correlation coefficients of 69 up to 82% in interpretation of regional geographical factors in estimating the annual and seasonal precipitation of basin is a good sign of the importance of processing statistical data in climatic studies and the use of geo-climate data. In the present study by using the mean of annual and seasonal precipitation records of the basin stations, the relation of the geographical parameters including the geographical latitude and longitude, the height above sea level, the distance from the mountain and the sea is modeled by multiple variables correlations method and precipitation rate is estimated.

Tea and sesame seed oils extracted by different methods (including supercritical fluid extraction (SFE), at a pressure of 350 atm, a temperature of 60oC, a static extraction time of 20 minutes, a dynamic extraction time of 30 minutes and 150 g kg-1 of ethanol as a modifier). Solvent (SE) and ultrasound-assisted solvent extraction (UE)), as natural anti-oxidants, were evaluated during 15 days storage by monitoring their effects on refined sunflower oil at 60oC. The peroxide value (PV) and the thiobarbituric acid (TBA) value were used to assess the antioxidant activity of these extracted oils. The highest extraction yields were from SE and SFE, while UE gave a lower yield. Considering oil extraction yield and antioxidant activity, SE and SFE were the preferred methods. The results showed that tea seed oil had strong antioxidant activity, which was almost equal to sesame oil. Therefore, tea seed oil can be used in the same way as sesame seed oil in fat, oil and other food products as a natural antioxidant to suppress lipid oxidation.

Recent research on the genus Lithostege Hübner, 1825 has raised questions about the taxonomic status of Lithostege amseli Wiltshire, 1967. Examination of the recently rediscovered holotype confirms its validity as a distinct species. Furthermore, we have now clarified the taxonomy of Lithostege amoenata Christoph, 1885, a species that was previously misinterpreted. Additionally, two new species of the genus Lithostege from Afghanistan and Tajikistan are described here (L. hausmanni sp. n. and L. viidaleppi sp. n.). The wing patterns and genitalia structures of the discussed species are illustrated, and their diagnostic characteristics are discussed.

Phenolic compounds, especially those of plant origin, constitute an essential part of the human diet, and are of considerable interest due to their antioxidant properties. In this study, Ultrasound-Assisted Extraction (UAE), Microwave-Assisted Extraction (MAE), as well as Maceration Extraction (ME) methods were applied for phenolic compounds’ extraction from pistachio green hull. Response surface methodology was employed to optimize the extraction conditions as regards the yield of the compounds. A Central Composite Design (CCD) was employed to investigate the effects of three independent variables, namely liquid-to-solid ratio (8-20 times), temperature (25-65 °C) and time (5-45 minutes) on the dependent variable (level of total phenolic compounds). The results indicated that within the same extraction time, the extraction yield through UAE was higher than those in ME and MAE methods. Correlation coefficients (R2) of the models for UAE, MAE and ME methods were 0.95, 0.96 and 0.94, respectively. The optimal conditions for extraction of phenolic compounds from pistachio green hull through ME, UAE, and MAE methods were 20(v/w), 65°C, 45 minutes; 20(v/w), 65°C, 25 minutes; and 20(v/w), 65°C, 45 minutes, respectively. Under optimized conditions the experimental values well agreed with the values predicted by the proposed models.

The purpose of this study was to investigate the possibility of producing a biodegradable film from a new source known as opopanax gum and investigating its physical and mechanical properties. Opopanax gum was purified after two extraction steps and the film was prepared with 4% gum solution and 2.5% glycerol in deionized water. The apparent viscosity of the film solution showed the non-Newtonian shear thickening behavior of the solution. The contraction ratio obtained from opopanax gum film was -0.267 ± 0.095. Water vapor permeability (WVP) of opopanax film was 25.059 ± 0.623. The tensile strength and the elongation percentage at break point obtained for opopanax gum film were 0.376 ± 0.124 MPa and 350.625±108.599, respectively. The opacity percentage of the film was 15.633 ± 0.404, which indicates the desirable clarity of the film. The average contact angle for the film was 34.618 ± 1.992, which can be said that the film is relatively sensitive to humidity. The X-ray diffraction spectrometer pattern showed the semi-crystalline structure of the film. Two endothermic peaks and two exothermic peaks were observed in the DSC thermograms. The thermal analysis of the film also showed 4 mass losses. The structure of the film was investigated using Atomic Force Microscopy. The FTIR test showed that the main part of the film is polysaccharide. The total results from different experiments showed that opopanax gum has the ability to form film. However, opopanax gum is not alone desirable to produce edible film due to its high thickness, high solubility in water, high permeability to water vapor and poor mechanical properties. Therefore, it could be an appropriate option for combining with other films to enhance biodegradability of the films.

In this paper, the extended Finite Element Method (XFEM) is implemented to compute the Stress Intensity Factors (SIFs) for rectangular media subjected to a hygrothermal loading. In governing hygrothermoelasticity equations, the cross coupled of temperature and moisture fields and temperature-dependent diffusion in some cases are considered. Furthermore, an interaction integral for hygrothermal loading is developed to compute the stress intensity factors. The non uniform mesh of isoparametric eight-nod rectangular element is used in XFEM to decrease the absolute error in SIFs computations. In order to numerical results validation, the SIF of mode I is obtained analytically. The coupled governing equations are firstly decoupled in terms of new variables and then solved by the separation of variable method. According to the results, the moisture concentration gradient has a significant effect on the SIFs so should be considered in the model. Up to reaching temperature to its steady state, the cross coupled of temperature and moisture synchronies their time variation which affects on the time variation of SIF. At early time of thermal shock, the SIF for shorter cracks is not necessarily lesser than the longer ones. Also, the mode I SIF for longer and inclined cracks is smaller. On the other hand, considering the moisture concentration as a temperature function increases the time required to reach the moisture steady state.

Deep frying is one of the most common operations used in food processing. But it is necessary to use methods to reduce the oil uptake and prevent the formation of toxic substances such as acrylamide, while maintaining the desired features. Accordingly, in the present study, the effect of microwave pre-treatment with the power of 2 and 5W / g and in 15 and 10 minutes respectively, on the amount of oil uptake and the amount of acrylamide formation in fried carrot pieces was investigated at two temperatures of 150˚C and 170˚C and in 2 and 4 minutes duration. According to the results, at all temperatures, with increasing of the frying time, the amount of oil and the acrylamide formation increased in all samples, but at the same frying times, control samples had higher oil uptake and acrylamide formation compared to the pre-treated samples. According to the investigations, the highest oil uptake and the highest amount of acrylamide formation were respectively measured in the samples fried at 150˚C in 4 min (6.12%), and the fried samples at 170˚C and in 4 min (18.49 ppb). However, the lowest amount of oil uptake and acrylamide formation in microwave pre-treated samples (with 5W/g power in 10 minutes) and samples fried at 170˚C in 2 minutes were respectively (3.78%) and (<4.67 ppb).

Lipid oxidation is important issues that can lead to the degradation and destruction of foods containing lipids. A number of antioxidants have been used to solve this problem. Stachys lavandulifolia is a medicinal herb with antioxidant properties. Given that the impact of new technologies compared to traditional methods in terms of saving time, energy, and increase the efficiency of extraction have been identified. The aim of this study was modeling the extraction of antioxidant compounds from Stachys lavandulifolia by ultrasound-assisted extraction method. For this purpose, to model the extraction efficiency of neural network antioxidant compounds, artificial neural network hybrids - genetic algorithm and response surface methodology were used. The best model was obtained based on the results of the neural network model with gradient optimization method, with trainbr training and tansig transfer function and the number of hidden layers of this combination with two neurons 8 in the first layer and 4 in the second layer. For this network structure, an error of 0.0128 and a correlation coefficient of 97.30% were determined. By comparing this method with the response level, the model accuracy increased from 92% to 94.68%. The best result for the hybrid model occurred in the trainbr learning algorithm with the tansig transfer function with a hidden layer and 18 neurons. The error rate and correlation coefficient in this method were equal to 0.0693 and 83.27%, respectively. According to the results of the neural network with the logger method, it answered better and the hybrid method of the genetic algorithm with the neural network was not a suitable model for prediction. Finally, it can be said that mountain tea can be considered as a potential source of antioxidant compounds and neural network can be considered as a successful application method to predict the extraction efficiency of antioxidant compounds.

The purpose of this research was to enrich apple leather with pomegranate seed oil encapsulated with chitosan-soy isolate protein particles and to further investigate the color, texture and organoleptic properties of apple leather. At first, chitosan-soy protein isolate complex particles were prepared and then they were used to stabilize pomegranate seed oil emulsions (20, 30 and 50% oil). The results of the creaming index showed that the 20% emulsion had the lowest amount of creaming index after 14 days of storage. Next, the droplet size and viscosity of the 20% emulsion were evaluated. The results showed that the size of the emulsion droplets was about 1 µm and the flow behavior of the emulsion was Newtonian. Then, the effect of pomegranate seed oil emulsion (0.2, 0.5 and 1%) on the color, texture and organoleptic properties of apple leather was investigated. The results of the sensory evaluation showed that the apple leather without emulsion had a lighter color compared to the samples with a higher percentage of emulsion. The overall acceptability of apple leather for the control and the sample with 0.2% emulsion was not significantly different, and therefore it can be said that the use of pomegranate seed oil in apple leather in the form of emulsion up to 0.2% is suitable.

Sometimes, determining the amount of damage and the time and place of its assessment in out-of-contract responsibilities is very difficult. Maybe the person who has incurred a loss does not claim damages or may not be able to do so immediately after the damage. Therefore, there might be a period from the presentation of the petition and compensation payment. Meanwhile, the value of money and the compensation payment might increase or decrease. Sometimes, the place of damage is different from that of petition and compensation payment, or the property is moved, which has different prices in different places; so, it is necessary to determine criteria for assessing the time and place of the damage. The present research is a library study, and the method employed is descriptive, analytical, and comparative. We first mention compensation payment and its practices, then according to the judicial procedure to determine the damage, the time and place of damage assessment in compulsory security and out-of-contract responsibilities have been examined comparatively in Iran and Egypt law are compared. Finally, it is concluded that in Iranian law, there is a difference between fungible and curator. In assessing the fungible in case of apology or loss, it is the price on the day of sentence execution and it is the last price. In curator properties, the day of sentence execution is determined. The assessment place is also determined based on the criteria of time, payment place, and sentence execution. Egyptian law does not differentiate between fungible and curator, and rather sets the day of sentence as the time criteria; place is not explicitly referred to either. The legal criteria of Iran are better as they are in line with the goals of civil liability.

Many studies have been performed on the effect of viscosity on the qualitative characteristics of hot crystallization in the cooking stage of beet factories. In this study, we tried to investigate the effect of newer viscosity reducing agents based on sucrose esters on the quality of cold crystallization in these units. For this purpose, a substance called cisterna which is a sucrose ester as a viscosity reducing agent in four levels  0 , 33, 66 and 100 ppm were used in weak effluent from centrifuge cooking of a beet factory at 55 ° C and its effect on viscosity, crystallization efficiency, color of extracted sugar solution and purity percentage of effluent from centrifuge sample was investigated. The results showed that the addition of this substance reduced the viscosity. Crystallization efficiency increased to 66 ppm and then decreased at higher concentrations. The color of the extracted sugar solution and the purity percentage of the effluent produced by centrifugation and separation of the solid phase from the liquid decreased to this concentration of surfactant and at higher concentrations these parameters increased. In general, the use of these materials in cold crystallization of sugar factories can increase the efficiency and reduce the waste of beet factories

Human ankle-foot gait is the result of a complex interaction between nerves and muscles. A significant number of prosthetic ankle-foots (passive, semi-active, active) have been designed to restore an identical function of a real limb. Excluding passive and semi-active prosthesis who couldn’t generate any positive work, one of the biggest challenges in creating these prostheses is providing the needed power and energy during movement. Supplying this power and energy, requires a high-torque and high-power actuator having high weight, thereby causing a dramatic increase in the weight and size of that prostheses. In this paper, a combination of an active actuator (an electrical motor) and an passive stimulus (a spring) is utilized, which decrease the needed power and energy, and in addition to walking mode can also support running mode up to 2.5m/s. Accordingly, The first stage of this article includes mechanical modeling of the ankle and evaluation of efficiency and power consumption in all presented models. Then the structure of Series Elastic Actuator differed with the previous structures is selected as the best combination.  In this opted structure, power and energy consumption is dramatically declined up to 58% and 26% in walking mode and 64% and 57% in running mode. Consequently, a lighter motor and battery can supply the required power, so the prosthesis chr('39')s weight is subtracted.

The purpose of this research is to encapsulate the phenolic compounds of rhubarb stem's juice with chitosan and soy protein isolate and checking their effects on the properties of pomegranate juice. For this purpose, the phenolic compounds of rhubarb stem's juice were extracted by methanol and encapsulated with chitosan and soy protein isolate by nanoemulsion method, and finally the resulting microcapsules and nanocapsules were used to enrich pomegranate juice samples. The highest percentage of encapsulation efficiency of phenolic compounds was with soy protein isolate (45.26%). The results of SEM images showed that the particles were relatively spherical and with a relatively smooth surface, also chitosan nanocapsules with an average size of 281.4 nm and soy protein isolate microcapsules with an average size of 22.33 µm were formed. The results of pH analysis showed that the samples enriched with chitosan nanocapsules and soy protein isolate microcapsules showed more and less pH decrease than the control samples during the storage period. The results of DPPH radical scavenging activity showed that the enrichment of pomegranate juice with chitosan nanocapsules increased the antioxidant activity of the samples for up to 3 months of storage.
