  Introduction: Early splitting Pistachio nuts in is one of the critical sources of aflatoxin contamination before and during harvest. In this research work physical characteristics,fungal, pest and aflatoxin contaminations were evaluated in early splitting pistachios.Materials and Methods: Physical characteristics, fungal contamination and aflatoxin content were assessed in pistachio nuts employing advanced methods. This study was carried-out using three varieties of commercial nuts consisted of Ohadi, Kalleghoochi and Ahmadaghaii.The data was analyzed in a randomized complete block design using Mstatc statistical analysis software.Results: The highest levels of Aspergillus infection was observed in early splitting pistachios with dry and semi-dry hull. These pistachios also had the highest levels of carob moth infestation and shell staining as well as low kernel weights. In early splitting pistachios with soft hull the fungal infection, carob moth and shell staining were 0.75-10.3%, 1.5- 9.5% and 21.5- 44.1% respectively. This indicates the critical effects of early splitting pistachios as well as the risk of aflatoxin formation. The results showed that the levels of Aspergillus infection are increased by the presence of carob moth and ants, while there was low kernel weight. Aflatoxin was not detected in pistachio with healthy hulls. On the other hand, shell and kernel of early splitting pistachios contain different levels of aflatoxins (P<0.05). Aspergillus flavus isolates was alike to produce 67% aflatoxins B1 and B2 and 24% aflatoxins B1 and 9% were nontoxigenic.Conclusion: Sorting out early splitting pistachios based on physical and appearance characteristics would reduce the levels of aflatoxins during or after processing. Early peaking is a critical factor to reduce fungal and aflatoxin contaminations. About 95% and 5% of aflatoxin contents were related to kernel and shell, respectively. Therefore, assessing the risk of contamination should be based on kernels. Manuscript profile

  In order to investigate the effects of nitrogen fertilizer amount and its spliting on rice (Hashemi variety) yield and nutrients uptake from urea source, was conducted in the National Rice Research Instituteduring during a two- year experiment. The study has been done based on a Randomized Complete Block Design (RCBD) with three replications. Increasing amount of nitrogen fertilizers based on urea source in four categories was as the first factor, i.e. 30, 60, 90, and 120 kg nitrogen ha-1 and the time of its application was as the second factor i.e. basal application at transplanting, two splits i.e. at transplanting and at the beginning of tillering, and three splits i.e. at transplanting, at the beginning of tillering and just before flowering. Results showed that yield and nitrogen uptake by grain and straw increased significantly by applying of increased amount of urea fertilizer and when the fertilizer was used in two or three splits application (P<0.01), except of the second year. The level of applied nitrogen had not any effect on the P concentration in grain. The concentration of the N uptake by plant affected significantly in the first year by increasing the split number to three (P<0.01). Furthermore, the results showed that increasing nitrogen application by 30 kg ha-1 was equivalent with increasing the splitting once.  Manuscript profile

  The main purpose of this study is to derive the price of American put option, when the interest rate follows a stochastic process. For this purpose, first underlying asset model is expanded to CIR stochastic interest rate model. Then, the problem of American option pricing under CIR stochastic interest rate model is formulated as a two-dimensional linear complementarity problem (LCP). We propose a two-cycle componentwise splitting method for solving this two-dimensional LCP. In this method, the two-dimensional LCP, obtained for the valuation of an American option, is decomposed into six one-dimensional LCPs in several fractional time steps, and then each LCP is solved numerically in two steps. So that in the first step, the tridiagonal systems of equations are solved, and then in the second step (update step), the obtained values of option prices are modified and updated according to the conditions of the American option pricing problem. Finally, the numerical results obtained by splitting introduced method are compared with the Monte Carlo simulation results Manuscript profile

  Flower buds and fruit abscission, production of blankness, non-split and deformed nuts are the most important physiological disorder in pistachio trees. The importance of plant growth regulators in alleviation of these disorders has been proved. In this project the effects of Epibrassinolid on alleviation of some of these problems in “Ahmad- Aghai” cultivar has been studied. The experiment was performed as factorial based on completely randomized design with 3 replicates in a commercial orchard at Rafsanjan (Kerman Province). The treatments consist of 0 (control), 0.5 and 1 (mg ml-1) epibrassinolid treatment in two stages (before and after full bloom). 0.5 (mg ml-1) epibrassinolid decreased the bud and fruit abscission while increased the fresh and dry weight and yield of branches. Epibrassinolid in the first stage decreased the blank fruit production and increased the split fruits. Epibrassinolid treatment obviously decreased the amount of ethylene in fruits while it had no significant effect on morphological characteristics. 0.5 mg ml-1 epibrassinolid was the best concentration and the first stage (a week before full bloom) was the best time for treatment in Ahmad- Aghai cultivar trees.

  Pre-harvest fruit splitting each year causing a significant reduction in yield and the prevalence of fungal rot in citrus fruits. In this research, effect of rootstock and also, physical traits of fruits on the severity of pre-harvest fruit splitting were investigated. For this purpose, a research was performed in 2016-17 based on RCBD statistical design with three blocks of three mandarin cultivars (Page, Kara and Cadoux) grafted on four rootstocks (Sour orange, Citrange, Citrumelo and Cleopatra mandarin) under dry farming condition in Tonekabon city (private orchard). Obtained results showed that, both two investigated factors had significant effects on this disorder. According to results, sour orange and citrumelo caused the highest and lowest fruit splitting respectively and two other rootstocks with no significant difference were at an intermediate level in this regard. The significant role of growth pattern, thickness and cell density of peel at the stylar end of fruits on pre-harvest fruit splitting, caused that Page and Cadoux have the highest and lowest percent of fruit splitting respectively. Results also showed that cell density on the peel of the split fruits was lower than healthy ones. Manuscript profile

  Production of hydrogen using photoelectrochemical water splitting is a promising method for production of clean and renewable energy source. Using positive and negative semiconductors respectively as photocathode and photoanode, water can be splitted into hydrogen and oxygen. In this study, hematite was synthesized using electrochemical deposition. The diffraction pattern obtained using x-ray diffraction showed hematite having rhombohedral crystal structure. Surface morphology obtained by scanning electron microscope showed a two-layer structure, lower layer with cracks and upper layer consisting of particles. Photocurrent density was obtained using linear sweep voltammetry under chopped illumination and it was obtained at 0.6V vs Ag/AgCl as 2.5 μA.cm-2. Nyquist plot of hematite at potentials of 0V and 0.6V was obtained using electrochemical impedance spectroscopy and an equivalent circuit was fitted to EIS data and the value of the parameters was obtained. Also, using Mott-schottky plot, the flat band potential and the carrier density were obtained to be -0.35V vs Ag/AgCl and 8.4×1018 cm-3. Manuscript profile

  Nowadays, implementation of simple and efficient methods for determining nitrogen needs has been considered in various plants. The simplest and most efficient methods for appreciate nitrogen requirement determination is leaf color chart (LCC). To determine of nitrogen fertilizer requirement in forage sorghum using leaf color chart, an experiment was conducted as factorial arrangement based on complete randomized block design with three replications at Agriculture and Natural Resources Research Station of Sabzevar in 2012 growing season. The factors were nitrogen rate in four levels including conventional (150), 25, 50, and 75 kg.ha-1 N and LCC scores was less than 4 and 5. The highest plant height, leaf dry weight, number of leaves per plant, biological yield and protein percentage were obtained in 75 and 50 kg.ha-1 nitrogen application. Using different amounts of nitrogen with reduction of LCC to 5 led to higher plants, more leaf dry weight, leaf numbers per plant, biological yield and protein content than using nitrogen with reduction of LCC to 4. On the whole, 50 kg.ha1 nitrogen with reduction of LCC to 5 was the best treatment for the highest quantity and quality yield achievement for forage sorghum. Also, LCC can be applied easily to determine sorghum nitrogen equipment. Manuscript profile
