Mayetiola destructor (Say, 1817) originated in the Fertile Crescent region of the Middle East and is one of the most serious pests of wheat, rye and barley and more than 16 Poaceae wild species. Here, we report the occurrence of this species as an invasive pest for the first time in Iran. It was detected in wheat fields and rye in Qüshchï Pass, Urmia environ, West Azarbaijan province (September 2020) as well as in wheat fields in Bil-e Savar, Ardabil province (July 2024). The diagnostic characters and its life history as well as the photographs of the adult male and female, larvae, puparium, male genitalia and wing venation are provided. This is the second species from the genus Mayetiola that has been reported from Iran. To prevent the spread of this destructive pest in Iran, suitable management practices are urgently needed.

Aims: The assessment of threats and vulnerabilities of critical infrastructure such as urban water infrastructure can, in many cases, significantly reduce vulnerabilities or minimize the consequences of a threat. The aim of this research was to evaluate the components of the contingency and impact severity of human-oriented and natural-based threats in urban water infrastructure.
Instrument and Methods: In this analytical-descriptive study, a library collection method, including the study of books, research, and domestic and International articles of researchers as well as Internet search was used. The data were collected by questionnaire and analyzed by Hazop model and Friedman test, using SPSS 21 software.
Findings: According to the experts, the highest scores were assigned to terrorism acts and suppression, and, ultimately, human error. The most critical type of threat was recognized as chemical attack, military attack, and drought by the Hazop model. The second threat was rocket attacks, earthquakes, and terrorism. The human error ranked next in critical threats. The military attack and drought were recognized as an unacceptable crisis and the probability of a flood, a military attack (ground) and human error were ranked one to three. The impact severity (damage) of the military attack (ground), earthquake, and chemical pollution were ranked one to three, respectively.
Conclusion: The most critical types of threats are chemical pollution in urban water infrastructure, military attack, and drought and are recognized as unacceptable crisis. The probability of flood, military attack (ground), and human error are ranked one to three, and the impact severity (damage) of the military attack (ground), earthquake, and chemical pollution are ranked one to three, respectively.

Abstract Placing Informaiton Technology staff in suitable job positions of employees, regarding their skills and knowledge is very important. However, percepting it as a difficult issue or inability in dealing with them leads to superficial, non-scientific and haphazard decisions within enterprises. The very important note in this matter is the large quantity and variety of indicators that affect the recruitment of IT staff, as well as the qualitative, vague and fuzzy nature of employment that makes it difficult to decide about selecting the righ professional. In this paper, after collecting the important criteria in evaluation of eight IT occupational groups, we define intervals for each of core skills in eight IT occupational groups by seeking experts opinions through Fuzzy Delphi technique.In the next step, we design a fuzzy expert system with Matlab fuzzy toolbox for IT personnel selection that its inputs are the score in each skill and the outputs are his/her grade in each IT occupational group. The findings of this research can be useful for managers in employeeing IT professionals and in their purposeful educational planning for IT occupational groups.

Employees good placement, regarding their skills and knowledge are issues that there is no doubt in their importance. However taking them difficult or inability in dealing with them, has been led to superficial, non-scientific and decisions without planning in that enterprises. The first step in a good decision making process in this case is identification of important employment criteria and their levels. But highly important are the large number and variety of indicators that affect the recruitment of IT staff. Though their qualitative, vague and fuzzy nature makes it difficult for making decision in IT professional selection. In this paper, after collecting the important criteria in evaluating of eight IT occupational groups, we defined intervals for each of core skills in eight IT occupational groups with asking from experts via Fuzzy Delphi method. At the next step, we designed a fuzzy expert system with Matlab fuzzy toolbox for IT personnel selection that it's inputs are person's score in each skill and uotputs are his/her grade in each IT occupational group. Key words: Selection, General

Due to the wide applications of gold nanoparticles, there have been great demands for their synthesis recently. Chemical methods produce pure and Non-dispersive nanoparticles, but these are quite expensive and potentially toxic to the environment. It has been suggested that the use of biological organisms and their components could be a suitable alternative for the production of nanoparticle in an eco-friendly manner (green synthesis). Using plant extracts for nanoparticle synthesis can be advantageous over other biological processes because it eliminates the elaborate process of maintaining cell cultures and can also be suitably scaled up for large-scale synthesis. In this study leaf extracts of Water cress, were used for green synthesis of gold nanoparticles. Gold nanoparticles were formed by treating an aqueous HAuCl4 solution by different amount of plant leaf extract as reducing agent at different temperatures. UV–visible spectroscopy was used for monitoring of the reaction progress. The synthesized gold nanoparticles were characterized with Dynamic light scattering (DLS) size analyzer, Transmission electron microscopy (TEM) and Fourier-transform infrared spectroscopy (FTIR). The results show that only a few minutes were required for the synthesis of gold nanoparticles at 60 °C and 80 °C by 1000 μl of plant extract, suggesting appropriate reaction rates in comparable to those of nanoparticle synthesis by chemical methods. TEM images showed that spherical nanoparticles (size, 10–50 nm) were obtained at higher temperatures and leaf broth concentrations. The analysis of FTIR bands show that the Polysaccharides and proteins are probably involved in the bio reduction and synthesis of nanoparticles.

Apples are the main horticultural crops grown in West Azarbaijan province of Iran. In recent surveys of apple orchards in Urmia and Miyandoab, West Azarbaijan Province, symptoms including branch and twig bark cracks, cankers, dieback and tree decline were commonly seen. Isolation of the fungi from cracked and cankered branches yielded fungal isolates with typical characteristics of the genera Paecilomyces and Paramyrothecium. Based on combination of morphological characteristics and sequence data obtained from ITS-rDNA and β-tubulin gene sequences for Paecilomyces isolates and ITS-rDNA region for Paramyrothecium isolates, they were identified as Paecilomyces formosus and Paramyrothecium foliicola. Results of the pathogenicity tests on detached shoots of ‘Golden Delicious’ and ‘Red Delicious’ cultivars showed that isolates of P. formosus were pathogenic only on ‘Red Delicious’ cultivar, but Pa. foliicola isolates were pathogenic on both cultivars and showed symptoms of infection. Re-isolation of the fungi from inoculated shoots confirmed Koch’s postulates. To the best of our knowledge, the involvement of P. formosus and Pa. foliicola in the development of canker disease of apple trees is reported for the first time. Also, Pa. foliicola is a new record to Iran mycobiota.

Wheat seeds harbor different microbial populations, which can be associated with each other in neutral, positive, or negative interactions. The present study investigated the interaction of fluorescent Pseudomonas and Xanthomonas translucens (Xt) as an important wheat seed-borne pathogen. In addition to P. fluorescens (A7) and P. chloroaphis (A4), which were previously isolated from the rhizosphere of potato as potent biocontrol agents, six more non-pathogenic Pseudomonas strains that were isolated from wheat seeds, were studied. According to the general biochemical tests and partial 16S rRNA sequences alignment, the isolated strains were closely related to the species of P. gessardii, P. orientalis, P. poae, P. koreensis, and P. cedrina. The Pseudomonas strains exhibit different antagonistic activities, such as phosphate solubilization, cellulase, protease, and lipase production. Also, they have an apparent inhibition effect under in vivo conditions against X. translucens. Seed treatment by these strains led to suppressing bacterial leaf streak disease incidence in an early growth stage. However, disease progress enhanced with the seedling growth, resulting in the treated plants' complete death. Only in treated seeds by P. fluorescens (A7), P. chloroaphis(A4), and P. orientalis (Ais119) decrease of AUDPC up to 83%, 74%, and 63% was achieved, respectively, compared with the untreated controls. Our results showed that some fluorescent Pseudomonas strains could cause delay at the beginning of the disease appearance due to competition or producing antimicrobial metabolites during that time. In contrast, some may be considered a threat, enhancing disease development through synergistic effects.

In this paper, friction of the contacted surfaces with random roughness distribution in nano scale has been modeled and simulated. So, firstly the modified friction model, AMM, was derived for the contact of the flat/rough surfaces based on the JKR contact, HK friction model and random distribution of Greenwood-Williamson (GW) model. The results show, modified AMM model predict higher friction force. It is more accurate than the earlier AMM model due to considering of the surface forces. Following, the obtained model was extended for evaluating of friction between a flat particle and the rough surface, and especially for the tip of the atomic force microscopic on the rough surface. Then the effect of geometric parameters of surface such as standard deviation of the asperities height and radius of the asperities peak on the friction between tip and rough surface was done. It was observed that normal load and friction force are increased with growing of the standard deviation of the asperities height while as the friction coefficient will be reduced. Furthermore, the normal load, the friction force, and also the friction coefficient are raised by increasing of the asperity peak radius. Finally, it was observed that variation of standard deviation of the asperity height has more influence on the friction than the radius of the asperity peak

Strawberry (Fragaria spp.) is broadly planted for its fruit, fragrance, color, taste, and sweetness. Some people are concerned about transgenic plants and their products. Furthermore, genetic diversity is one of the basics of plant breeding programs. Polyploidy induction is one of the solutions to create genetic diversity and to reduce the concerns about transgenic plants. This experiment was conducted in a randomized complete block design to induce polyploidy in strawberry (Fragaria spp. cv. Kurdistan) using different concentrations of colchicine. We aimed to examine the possibility of polyploidy induction, to determine the best concentration, and to evaluate strawberry responses to polyploidy. The tetraploidy percentage in the plants treated by 0.7% colchicine was more ‎than 80%. Tetraploid plants had a greater fruit ‎length and diameter, fresh fruit weight, and larger fruit ‎volume than the controls. Such plants had ‎a lower stomata number with a larger size and a larger chloroplast number ‎ than the diploids. ‎Ultimately, considering the flow cytometry results, and the number of modified plants, the best concentration was 0.7% colchicine treatment, which could be used as a suitable concentration for ploidy induction in strawberries.

The task of the intake air manifold of gasoline engines is to transfer air, crankcase vapors, blow-by flow, fuel tank vapors, and fuel injected into the passages of the engine cylinder head. This part must be designed in such a way that it can supply the air needed by the car engine in different conditions of its operation with the lowest pressure drop and speed and distribute it equally between the engine cylinders in terms of flow rate and air-fuel ratio. Also, the mixing of oil vapors, blow-by flow and gasoline vapors of the engine is done in it and distributed equally between different cylinders. To achieve this goal, the air manifold needs to be designed in the most optimal way. In this research, the EC5 engine has been examined. The intended engine is designed and simulated in GT-SUITE software and the desired information for this modeling is practically extracted. The model designed in the software has been validated using experimental results. Then, using the desired model, the resonance volume in the air manifold has been investigated. Two engine models have been designed and compared using resonant volume and without using resonant volume in the inlet air manifold. The results of this comparison show that the engine with resonance volume had an increase in power of about 10 kW at engine speed of 6000 rpm

: The post-colonial conditions provided a good opportunity for Muslim women to shift their strategic position from a unit of analysis for westerners to the agent of active knowledge production. For many, Islamic feminism is considered as an alternative knowledge to bring about an epistemological emancipation from Orientalist ideas. Nevertheless, the present study shows, this is not free of ambiguity and problems. This study focuses on a book entitled Women and Gender in Islam by Leila Ahmed (1992) as one of the most influential sources of Islamic feminism, which is considered as an international academic source and is part of the most frequent textbooks in syllabi in American universities for decades Regarding the issue of the current article, that is, the challenges of thinking on the boundary of Islam and modernity for Muslim women, the supremacy of presuppositions and modern gender ideas have been explored in Islamic feminism. This superiority of discourse is to the extent that by using the critical discourse analysis method and understanding intertextual connections with other first-hand Islamic historical and jurisprudential sources, Ahmad's reading can be much distorted. As such, the paper tries to unveil the necessity of re-considering internal ambivalences and discursive complications of the book, considering its logic in approaching early marriage, polygamy, and veiling through Ahmed's creation of complex binaries such as Jahiliah (ignorance) vs. Islam and the Prophet vis-a-vis his female counterparts.
