Sustainable agriculture refersp to the correct management of agricultural resources that, while meeting changing human needs, and preserve the quality of the environment and the capacity of water and soil resources. Among the components of sustainable agriculture, we can mention the agroforestry system, integrated pest management, crop rotation, and intercropping. The purpose of intercropping is to find plants that have the least competition with each other and use the available resources more effectively. The purpose of this research is to the effect of intercropping of Roselle on the quantitative and qualitative traits of borage under foliar application of iron fertilizer and to determine the best ratio of intercropping to achieve the highest yield and the highest level of land equivalent ratio.

This research was carried out in the educational research farm of the Faculty of Agriculture of Zabol University in the agricultural year of 2014-2015. The experiment was carried out as a factorial in the form of a randomized complete block design with three replications. The treatments examined in this research include foliar spraying of sulfate fertilizer as the first factor in three levels including |(no foliar application or control, 3gr.l-1 and 6gr.l-1) and eight levels of intercropping including (pure Roselle, pure Borage, 75% Roselle + 25% Borage, 75% Borage + 25% Roselle, 50% Roselle + 50% Borage, 50% Roselle + 100% Borage, 100% Roselle + 50% Borage, 100% Roselle + 100% Borage were as the second factor. Both plants were planted at the same time at the end of March in 2×2 plots, where the distance between the planting lines was 50 cm, the distance between the rows was the same, but the density was different in each row. Irrigation was done according to the needs of the plants, weeding and thinning during the growth period and weeding was done by hand during three stages. Wagner's method was used to measure the amount of anthocyanins. The criterion for evaluating intercropping was using the land equivalent ratio. At the end, data analysis will be done using SAS version 9.1 software, and a comparison of means will be done using Duncan's test at the 5 % level.

Results showed that the interaction effects of foliar application, iron, and intercropping were significant on the anthocyanin and mucilage content of borage. Additionally, the simple effects of foliar application of iron were significant on the number of flowers per stem, stem height, number of sub-branches, biological yield, and harvest index. The effects of intercropping were significant on the number of flowers per stem, anthocyanin content, mucilage content, stem height, number of sub-branches, economic yield, and harvest index. The comparison of means effects of different intercropping systems showed that the highest biological yield (1412.8 kg.ha-1) was obtained from the intercropping system of 75% Roselle + 25% borage. In addition, the comparison of means effects of different intercropping systems showed that the highest amount of economic yield (49.68  kg.ha-1) was obtained from the treatment of pure borage cultivation. Comparison of means showed that the highest percentage of mucilage with an average of 0.0713% from the foliar treatment of 6gr.l-1 of iron sulfate in the conditions of pure borage cultivation, and the lowest percentage of mucilage was obtained with an average of 0.0280 from the control treatment (no application of iron sulfate fertilizer + 100% Roselle + 50% borage). The highest land equivalent ratio (2) was obtained from intercropping of 100% Roselle + 50% borage harvest.

According to the results obtained in the present study, the effects of foliar application of iron and intercropping systems had significant effects on yield and yield components of borage. By increasing the foliar application of iron improved growth traits and yield. The highest proportion of LER obtained was from 100% Roselle+ 50% borage, which indicated superior cropping compared to pure crop. This superiority is probably due to the better use of mixed components of growth resources such as light, water, and nutrients compared to pure crop.

Root-knot nematodes, Meloidogyne spp. cause 5% of the global crop losses. Silver nanoparticles (AgNPs) are a potentially effective nematicide. There are many methods to synthesize metallic nanoparticles, including using organic compounds, which are clean and environmentally friendly. In the present studies, the efficacy of as-synthesized AgNPs using Malva sylvestris extract (Ms-AgNPs) on egg hatching and mortality of the second-stage juveniles (J2) of M. javanica in vitro, and on the growth parameters of nematode infected tomato plant under greenhouse conditions was investigated. The results showed that increasing Ms-AgNPs concentration decreased the hatching rate and increased the mortality of J2. Ms-AgNPs at 107, 164 and 250 ppm reduced J2 numbers by 30, 50, and 70%, respectively, and were established as lethal doses for nematode control. Ms-AgNPs at a dosage of 250 ppm reduced the number of eggs in the root system and the nematode reproduction factor by 60.4 and 56.3%, respectively, and increased shoot length and shoot fresh weight by 11.2 and 14%, respectively. Ms-AgNPs at a very low concentration reduced the population of M. javanica without causing any harmful effects on tomato. Therefore it can be used in nematode control strategies due to its environmentally friendly composition.

Security drills in the West Asian region have always been of strategic importance. On the other hand, the role of Iran as one of the main countries in the security dynamics of the region is of particular importance. Since when and how has the Islamic Republic been influencing the security order of the region and changing the pattern of friendship and enmity? This study seeks to investigate the impact of the Islamic Republic of Iran on the evolution of the security model in the region. One of the most important findings of this study is that the Islamic Republic, especially after the US invasion of Iraq, has played a prominent role in regional security developments and the security model of the region from the balance of power (between the Soviet :union: and the US) before the Islamic Revolution to the balance of fronts. Western Front and Resistance Front

The Root-knot nematodes (Meloidogyne spp.) are one of the most damaging plant pathogens with a wide host range and cause major losses to agricultural crops. The use of resistant cultivars is considered a safe, economical, and effective method to control these nematodes.

In the present study, eight melon cultivars namely Ahlam, 105, Tracey, Ronak, Deltagrin, Mac, Holar, and Veno were evaluated for their response to M. javanica. The seeds were planted in 2 kg pots and maintained under natural conditions in Khormuj city, Bushehr province. Seedlings at the four-leaf stage were inoculated with 5000 eggs and second-stage juveniles. The factorial experiment was conducted in a completely randomized design with five replicates. Sixty days after nematode inoculation, the plants were harvested and the plant growth and nematode population indices were evaluated.

The results showed that the nematode reproduction factor was significantly lower in Ronak, Deltagrin, and Veno than in the other cultivars. No significant difference was observed in shoot fresh weight of nematode inoculated and non-inoculated plants of Ronak cultivar.

Ronak, Delta-green and Veno cultivars are less susceptible to M. javanica.

The European countries have adopted a particular policy and manner to conflict with Muslims in their countries. These policies are classified into three behavioral patterns of British, German, and French. The British model is cultural pluralism, the German is Muslims’ integration in German society, and the French are melting melt pot. In their belief, Muslims must be dissolved in French culture and eliminated their religious identity. Other European countries follow one of these three models. The present study aimed to answer the following questions: ‘What effect have these strategies and patterns had on the living conditions of Muslims and the whole society of that country?’ ‘Were the approaches a plan or practical?’ ‘Which policies have been more successful quickly or strictly in confronting Islamic extremism (Takfiri terrorism) and Secular extremism (European terrorism)?’ ‘What was the practical result of these approaches in the Western European countries' social and security conditions?’

Moringa oleifera seeds are known for their high protein and vitamin content. Antioxidants are abundant in these seeds. Aqueous extraction was done. After that, an acute toxicity test was performed. The purpose of the study was to see how a graded dose of M. oleifera aqueous seed extracts altered testicular pathology, gonadal and extragonadal sperm reserves in Wistar rats infected with Trypanosoma brucei brucei. The rats were A, B, C, D, and E were randomly assigned to five groups with group E serving as the control group. The rats in Groups A to D were inoculated intra-peritoneal with 1× 106 virulent T. brucei brucei, and they were held for one week to demonstrate clinical signs before starting the extract therapy. Every day at 10:00 a.m., the rats were given treatment for five weeks with (75, 100, 125, and 150) mg/kg of M. oleifera aqueous seed extract for groups A, B, C, and D respectively. While the control group E received 0.5 mL/kg of water. For hema-tological indices, blood samples were collected every Monday between 10:00 and 11:00 a.m. All of the rats were humanely sacrificed at the end of the six-week experiment, and their gonadal and extragonadal sperm stores were collected, tested, and processed for histopathology. After treatment, the rats' gonadal and extragonadal sperm reserves (groups A to E) showed a substantial increase (213±1.1a; 221±2.1; 250±0.0c; 259±2.6d; 295±2.6e) × 106 and (115±1.1; 160±2.1; 153±0.0; 167±2.6; 120±0.6) × 106 respectively, compared to control group at P < 0.05 level. Sperm concentration of the right epididy-mis (60.0±1.1a; 90.2±2.1b; 96.5±0.0c; 98.7±2.6d; 69.4±0.6e) × 106 were significantly higher compare to the left epididymis (55.0±1.1; 69.8±2.1; 56.5±0.0; 68.3±2.6; 50.6±0.6) × 106. The PCV (%) and WBC (103/μL) levels in groups A, B, and C were significantly greater following infection than that in group E. Infection with T. brucei at weeks 2 and 3 shows poor semen characteristics, thereafter the semen quality has improved. Moringa oleifera aqueous seeds extract has drastically abridged the impact of trypanosomosis and enhanced the semen quality of the experimental rats.

The issue of the future of Islam and Muslims in Western Europe is an important issue in scientific and political circles. This issue has taken on special security and political dimensions due to the emergence of terrorist groups and operations in the Middle East and Western European countries. In this study, according to the methods of futurology and scenario writing, possible and probable scenarios for the future of Islam and Muslims in Europe have been proposed. Four optimistic scenarios: coexistence and cultural diversity and freedom of action of Muslims; Pessimistic scenario: de-Islamization and secularization of Islam; the miracle scenario: the domination of Islam over Europe and the catastrophe scenario: the mental and practical isolation of Muslims and the increase of tensions are considered as possible scenarios and then each of them has been evaluated and validated. The most likely prediction is a combination of different approaches, especially the integration and promotion of individual Islam and the continuation of Islamophobia may be predicted as current for the future of Islam and Muslims in Western Europe.

The use of structural vibration is one of the bridge health monitoring approaches which is often costly, time-consuming. The response of a passing vehicle includes the bridge response so that it is used for extracting the bridge modal parameters. In this paper, the transmissibility measurement of a passing vehicle is employed in order to identify the bridge mode shape indirectly. As the sensor is embedded on the axle of the vehicle, recording the signal is fulfilled during the vehicle passage and there is no need to stop the vehicle. On the other hand, there is white noise assumption in most other techniques, but excitation characteristics are not considered in the proposed method which is another advantage. In the numerical simulation, the bridge is assumed to be Euler Bernoulli and the vehicle is modeled as a 4DOF system. Solving the vehicle-bridge interaction equations, the acceleration of all degrees of freedom are obtained. Afterwards, the mode shape is identified by applying the short time transmissibility measurement on the acceleration. Since the performance of the indirect methods in real cases is associated with many obstacles and challenges, a setup for experimental verification of the proposed method has been designed and constructed in a laboratory. Numerical simulations and experimental results indicate the capability of the proposed method for indirect identification of bridge mode shape.

Root-knot nematodes, Meloidogyne species are among the most critical plant-parasitic nematodes attacking okra Abelmoschus esculentus (L.) Moench in tropical and subtropical regions. In the present study, the effects of various levels of zinc and iron on okra infected with M. javanica were investigated under greenhouse conditions in a completely randomized factorial design with five replications. Four-leaf stage seedlings of the susceptible okra, cv. Clemson Spineless were inoculated with 8000 eggs of M. javanica per pot. Five days later, the soil of each pot was treated with a combination of iron or zinc (0, 1, 3, and 6 mg∙kg-1 soil) from nano chelated iron and zinc fertilizer sources. Sixty days after inoculation, plants were harvested, and okra growth indices and nematode population indices were determined. Results showed that vegetative indices increased in most cases compared to non-treated plants. Fruit fresh weight of inoculated plants treated with iron at the rate of 1 mg∙kg-1 soil + zinc at the rate of 3 mg∙kg-1 soil from nano chelated iron and zinc fertilizer sources increased by 205%, compared to inoculated control plants. Combined application of iron at the rate of 6 mg∙kg-1 soil + zinc at the rate of 6 mg∙kg-1 soil from nano chelated iron and zinc fertilizer sources reduced the number of eggs, galls, and egg masses per root system and the reproductive factor (224, 415, 455 and 231%, respectively) compared to non-treated plants.

The beauty of the gerbera flower depends on the lifespan of its petals. The lifespan of the petals depends on preserving the relative water content and the metabolic activity of the petals cells. The flower producers use compounds that protect and enhance the metabolism of the cells, as well as prevent the invasion of bacterial pathogens and the ability to maintain the water's potential for petals tissues. The present study was conducted to determine the lifespan and metabolic activities of the petals tissues under thyme essence and salicylic acid effects. Treatments were different concentrations of thyme essence (0, 150, 300, 600 μl L-1) and salicylic acid (0, 500, 1000, 2000 μM L-1) and their simultaneous use in aqueous medium. The treatments were sorted in the factorial experiment (4×4) on a randomized complete block design with three replications in laboratory conditions. The variables were lifespan, relative water content, activity of enzymes (phenylalanine ammonia lyase, peroxidase and catalase), malondialdehyde content and anthocyanin content in the petals cells. The most important results showed that 600 μl L-1 of thyme essence in the container of the cut flowers due to its antioxidant and antibacterial properties, increased the lifespan of the flowers compared with the control for 4 days. Also, 2000 μM L-1of salicylic acid due to the improved ability of the tissue defense system of the petals via arising of the resistance to oxidative stress of cells increased the life span of the cut flowers from 4 days to 8 days.

Althaea officinalis L., Lavandula angustifolia Mill. and Rosa x damascena Herrm. are used to treat excision or burn lesions in traditional medicine.

To evaluate the healing effect of a polyherbal ointment containing L. angustifolia, R. x damascena, and A. officinalis combination on wounds caused by third grade skin cut.

To evaluate the wound healing effect of this polyherbal formulation, an ointment containing the extract of A. officinalis, the essential oil of R. x damascena (2 % essence) and the essential oil of L. officinalis (2 % essence) in an eucerin base (20:20:10:50) was prepared. The formulation was examined using excision wound test for 14 days and the percentage of healing effect in each group was calculated. Formalin induced rat hind paw edema method was used for determination of anti-inflammatory activities of the same formulation.

The percentage of recovery in the polyherbal formulation group was significantly higher than the other groups. Histological studies also confirmed these results. Herbal formulation treated group showed significant improvement in terms of re-epithelialization, angiogenesis, collagen deposition, and reducing inflammation. The percentage of wound healing was 99.07 ± 0.34, 99.22 ± 0.35, 98.45 ± 0.733, 98.75 ± 0.88 and 63.72 ± 5.64, for the polyherbal formulation, L. angustifolia, R. damascena, A. officinalis extracts, and the placebo group, respectively.

This polyherbal formulation could act as a wound healing agent, possibly due to the suppression of inflammatory mediators. The presence of phenolic compounds might be a reason behind the therapeutic effect of these plants.

There are various automatic programming models inspired by evolutionary computation techniques. Due to the importance of devising an automatic mechanism to explore the complicated search space of mathematical problems where numerical methods fails, evolutionary computations are widely studied and applied to solve real world problems. One of the famous algorithm in optimization problem is shuffled frog leaping algorithm (SFLA) which is inspired by behaviour of frogs to find the highest quantity of available food by searching their environment both locally and globally. The results of SFLA prove that it is competitively effective to solve problems. In this paper, Shuffled Frog Leaping Programming (SFLP) inspired by SFLA is proposed as a novel type of automatic programming model to solve symbolic regression problems based on tree representation. Also, in SFLP, a new mechanism for improving constant numbers in the tree structure is proposed. In this way, different domains of mathematical problems can be addressed with the use of proposed method. To find out about the performance of generated solutions by SFLP, various experiments were conducted using a number of benchmark functions. The results were also compared with other evolutionary programming algorithms like BBP, GSP, GP and many variants of GP.

Ethnomedicinal plants are of interest for treatment of various wound types.

This study aimed to evaluate burn wound healing potential of the hydro-alcoholic extract of the flowers of Lilium candidum L. in rats.

DPPH free radical scavenging power, total flavonoids, and the phenolic content of the extract were evaluated. Following burn wound induction, 30 Wistar rats were divided into 5 groups; silver sulfadiazine cream 1% (reference standard), eucerin (control), and 5%, 10% and 20% ointments of L. candidum flowers extract (treatment groups). Wound contraction and the percentage of wound healing were measured every day until 14th day and the histological changes were evaluated.

DPPH assay of L. candidum extract indicated high antioxidant activity. Total phenolic content of L. candidum extract was equal to 157 mg gallic acid equivalent/g; while total flavonoid was measured as 32.4 mg quercetin equivalent/g dried extract. The mean of wound area was significantly different in three 5%, 10% and 20% extract-treated rats in comparison with the control. Although, 20% ointment of L. candidum flowers extract demonstrated the best wound healing improvement, even better than silver sulfadiazine. Histopathological analysis confirmed the wound healing activity of L. candidum and promoting tissue repair, especially for the ointment containing 20% extract.

Regarding the high content of phenolic compounds and flavonoids, besides potent antioxidant properties of the flowers of L. candidum, the use of its ointments led to significant decrease of burn wound area, suggesting that these extract ointments can treat burn wounds and improve the healing processes.

Root-knot nematodes (Meloidogyne spp.) are among the most dangerous herbal parasites which destroy 8.8 to 14.6 percent of agricultural products annually. In vegetables, 50 to 80 percent damage caused by nematodes is normal. It is unavoidable to use safe methods for controlling root-knot nematodes. Plant parasitic nematodes can be inhibited using chemical fertilizers, which reduce the losses induced by plant parasites and increase total products. The aim of this study was to evaluate the effect of different levels of two macronutrients including nitrogen and phosphorous on the infection of M. javanica on eggplant (cv. Black Beauty) under greenhouse conditions.

In the current study, the levels of zero (N0), 50 (N1), 100 (N2), 200 (N3) mg nitrogen and zero (P0), 50 (P1), 100 (P2), 200 (P3) mg phosphorus per kg of soil were selected from nano-chelated nitrogen fertilizer and nano-chelated phosphorus fertilizer, respectively. The seeds of eggplant were planted in plastic pots containing 2 kg of culture media including equal amount of sand, farm soil and animal manure under greenhouse condition. The pots were irrigated daily and maintained at 27±4 °C with 16:8 h light: dark photoperiod. Four leaf stage seedlings were inoculated with five eggs and second stage juveniles of M. javanica per gram of soil, and 10 days after inoculation, different levels of fertilizers were added (100 ml per pot) to the pots through irrigation. Sixty days after inoculation, plant growth indices including shoot height, shoot fresh and dry weights and root fresh weight of the cultivated plants were recorded. Nematode population indices including number of galls and egg masses per root system, number of eggs in egg masses were also measured and finally the reproduction factor was calculated. The roots were gently washed with tap water and number of eggs in one gram of root were counted according to the procedure developed by Hussey and Barker (1973). One gram of root was stained with acid fuchsine according to the procedure developed by Byrd et al. (1983). The total number of eggs, galls and egg masses per plant root system was determined by multiplying with the root weight per plant. The final nematode population per pot was computed and finally, the reproductive factor (RF) of nematode was calculated by dividing the final nematode population by the initial nematode population (10000 eggs and second stage juveniles of M. javanica). Data on plant growth and nematode indices of the experiments were subjected to a factorial analysis of variance (Two-way ANOVA). Means were compared with least significant differences (LSDs) to identify significant difference at probability levels of P≤0.05 using SAS 9.1 software (Statistical Analysis System Institute Inc., USA) in a CRD (completely randomized design) with four replicates.

In nematode inoculated plants, the difference between shoot height and shoot fresh and dry weight of treated plants by phosphorus at the rate of 100 mg/kg soil and non-treated by nitrogen (N0P3) with control plants (N0P0) was significant. Similar results were observed in nematode inoculated plants treated by nitrogen and phosphorus at the rate of 50 and 100 mg/kg soil, respectively (N1P3), with nematode inoculated plants treated by nitrogen at the rate of 50 mg/kg soil and non-treated by phosphorus (N1P0), nematode inoculated plants treated by nitrogen and phosphorus at the rate of 100 and 100 mg/kg soil, respectively (N2P3), with nematode inoculated plants treated by nitrogen at the rate of 100 mg/kg soil and non-treated by phosphorus (N2P0) and also nematode inoculated plants treated by nitrogen and phosphorus at the rate of 200 and 100 mg/kg soil, respectively (N3P3), with nematode inoculated plants treated by nitrogen at the rate of 200 mg/kg soil and non-treated by phosphorus (N3P0) (P≤0.05). The results showed that using 100 mg nitrogen and 100 mg phosphorus per kg of soil from nano-chelated nitrogen fertilizer and nano-chelated phosphorus fertilizer, as the best treatment used in this experiment, decreased number of eggs, galls and egg masses per root system and reproduction factor of nematode by 53, 52, 62 and 55%, respectively. Therefore, nano-chelated nitrogen and phosphorus fertilizers, as two chelated fertilizers produced using nanotechnology, can decrease the population of M. javanica in eggplant cultivated in the greenhouse. Soil drenching of these water-soluble nano-fertilizers 10 days after infection of the eggplants by M. javanica can also reduce the population of nematode.

Root-knot nematodes(Meloidogyne spp.) are the most important parasitic nematodes infecting cucurbits plants. These nematodes cause 5% loss in crop production and also provide favorable conditions for co-infection with other plant pathogens. Trichoderma harzianum Rifai is a potential bio-control agents for controlling the plant pathogens, including plant parasitic nematodes. In order to find the effective isolate/s of T. harzianum for management of root-knot nematodes on cucumber, a suspension of 107 spores/ml of four isolates of T. harzianum with 36, 39, 42 and 43 codes was evaluated by soil drenching method. Twenty four hours after soil drenching of fungus isolates, four leaf stage seedlings of cucumber (cv. Super Dominus) were inoculated with 2000 eggs and second stage juveniles of Meloidogyne javanica and kept for two months in the greenhouse and the experiment was conducted as a completely randomized design with four replicates. The results showed that the isolate Th42 was the most effective isolate on reducing the biological activity of nematode as compared to other treatments. The isolate Th42 reduced the number of eggs, galls, egg masses and reproductive factor by 69.2, 81.8, 88.6 and 70%, respectively, as compared to control treatment.

Excitements are important for the proper interpretation of actions as well as relationships among human. Recognizing emotions through Electroencephalogram (EEG) allows the ability to recognize emotional states without traditional methods, including filling in the questionnaire. Automatic emotion recognition reflects the excitement of the individual without clinical examinations or need to visits, which plays a very important role in completing the Brain-Computer Interface (BCI) puzzle. One of the major challenges in this regard is first to select and extract the proper characteristics/features of the EEG signal, in order to create an acceptable distinction between different emotional states. Another challenge is to select an appropriate classification algorithm to distinguish and correctly label the signals associated with each emotional state. In this paper, we proposed to use Sparse Representation-based Classification (SRC) which addresses both of the mentioned challenges by directly utilizing the EEG signal samples (no need to involve with feature extraction/selection) and then classifying the emotional classes based on class dictionaries which are learned to represent the sparse model of the data of each emotional state. The proposed method is tested on two databases, the first of which is experimentally recorded in our biomedical signal processing lab and the subjects were excited by auditory stimuli, and the second database is taken from Shanghai University, China, in which the subjects were excited by visual stimuli. The results of the proposed method provides more than 80% accuracy for the recognition of two positive and negative emotions and suggest that the proposed method has higher degree of success in the classification of emotions while it avoids the complexity of feature selection/extraction.

The aim of this paper is identifying the parameters of for a double-ended magnetorheological damper with different sizes of iron- powders suspended in magnetorheological fluid. There is not any published work in literature about identification of parameters of spherical iron particles with different particle diameters in magnetorheological fluids. Hence, in at first, two different magnetorheological fluids with different diameters of iron particle and same volume percentage are prepared. Then, using a double-ended magnetorheological damper, dynamic displacement tests with harmonic excitation in different frequencies and using different electric currents are conducted. The parametric Spencer model is selected for modeling the damper and identifying its parameters. 10 parameters of this model are identified, using nonlinear least square solver and implementing for damper, using two different magnetorheological fluids in different frequencies and different electric currents. The appropriate polynomials are extracted for parameters that have systematic trends with increasing electric current. experimental hysteresis curves in different electric currents, excitation frequencies and different fluids, it is to assess the capability of Spencer model in regenerating the experimental counterparts. The comparisons of the hysteresis curves obtained from with identified parameters by the experimentally achieved counterparts show that this model has adequate compatibility with experiments in predicting force-velocity hysteresis curves. However, the implemented model has not enough success in predicting the force-displacement hysteresis curves, especially in sharp ends of the curves and force delaying regions.

Gorgan in Golestan province is substantially considered as an important region for production of agricultural crops in Iran. Plant-parasitic nematodes may cause direct or indirect damages to the plants in this region. Although some members of Merliniidae, Telotylenchidae or Pratylenchidae (Nematoda: Tylenchoidea( have been reported from different crops of Gorgan so far, there is no adequate and accurate information on these nematodes in association with many agricultural crops in Gorgan for making decisions on their management. The aim of the present study is to identify plant-parasitic nematodes of these three families in the agricultural field crops of Gorgan region and to determine their frequencies in the studied area. In order to identify the plant parasitic nematodes from the families of Merliniidae, Telotylenchidae and Pratylenchidae associated with the important field crops of Gorgan, Iran, 64 soil samples were collected from different parts of the region during 2014-2015. The nematodes were extracted, fixed and transferred to anhydrous glycerin. The permanent slides were prepared from the extracted nematodes and necessary measurements were made. Finally, the nematodes were identified based on morphological and morphometric characters, using available identification keys. In this study, 11 species belonging to seven genera were identified as Amplimerlinius macrurus, Merlinius brevidens, M. microdorus, Paramerlinius hexagrammus and Pratylenchoides ritteri from family Merliniidae, Tylenchorhynchus brassicae and T. crassicaudatus from family Telotylenchidae, and Pratylenchus neglectus, P. sefaensis, P. thornei and Zygotylenchus guevarai from family Pratylenchidae. Tylenchorhynchus crassicaudatus was found in the rhizosphere of soybean plants in Gorgan. Description, morphometrics, line drawings and photomicrographs were provided for this new record of nematodes. Among the identified species, P. sefaensis, M. brevidens and M. microdorus were the most distributed species, with 26.6, 25.0 and 23.4 % relative frequencies, respectively. Tylenchorhynchus crassicaudatus is reported for the first time in Iran and cited here. Furthermore, differences of morphological and morphometric characters of this species with other closely related species namely T. thermophiles, T. paratriversus, T. kashmirensis and T. mashhoodi are discussed. The morphological and morphometric characters of the present population are congruent to those of the type population type, except for hyaline region of tail being slightly shorter (4-7 vs 7-13 µm). Our population differs from the closely related species in some features related to female tail (shape, length and the number of annuli on the ventral side), in the absence of post-rectal sac, spicules and gubernaculum lengths, distance of DGO from stylet knobs and position of vulva.

In order to identify the plant-parasitic nematodes associated with medicinal plants in Boyer-Ahmad region, Iran, 84 soil and root samples were collected during 2015-2016. The nematodes were extracted from soil samples, according to the sieving-centrifugal flotation method, and then fixed and transferred to glycerin according to the modified De Grisse’s method. Identification of the nematodes insides the roots was also done with the Hooper’s staining technique. After microscopic observations of the permanent slides, the necessary measurements were made. Finally, the extracted nematodes were identified at species level using available diagnostic keys. In this study, 28 species belong to 14 genera were identified as follow:Amplimerlinius globigerus, Aphelenchoides cyrtus, A. haguei, A. varicaudatus, Helicotylenchus digitiformis, H. digonicus, H. exallus, H. pseudorobustus, H. varicaudatus, H. vulgaris, Longidorus africanus, Meloidogyne hapla, M. javanica, Merlinius brevidens, Mesocriconema antipolitanum, M. lobellum, Nagelus obscurus, Pratylenchoides ritteri, Pratylenchus cruciferus, P. curvicauda, P. delattrei, P. neglectus, P. sefaensis, P. sudanensis, P. thornei, Rotylenchus cypriensis, Scutylenchus rugosus, Xiphinema pachtaicum, Zygotylenchus guevarai.
Mesocriconema lobellum and Pratylenchus sudanensis were recovered from the rhizosphere of marsh-mallow and horehound plants, respectively and are reported for the first time from Iran here.

One of the most devastating plant parasitic nematodes of the world is the root lesion nematode Zygotylenchus guevarai. This nematode was recorded from most of the countries in association with the roots of various hosts. In a lovage (Levisticum officinale ) farm with vascular wilt symptoms at Boyer-Ahmad county, the fungus Fusarium oxysporum was isolated from the infected roots and plant-parasitic nematode Zygotylenchus guevarai was also recovered from the roots and rhizospheric soil. After that, infected lovage plants with Z. guevarai were treated by 0.0, 0.05 and 0.1 g cadusafos (Rugby)/Kg of soil. The experiments were carried out in a completely randomized design with four replications under greenhouse conditions and distilled water treatment was used as control. Results showed that Rugby with concentration of 0.05 g/Kg of soil showed 81, 47.9 and 48 while concentration of 0.1 g/Kg of soil showed 91.4, 73.7 and 73.5 percent reduction of nematode population in soil, final population and reproduction factor, respectively. Also, Rugby with concentration of 0.05 and 0.1 g/Kg of soil showed 281 and 149 percent increase in nematode population in root, respectively.

This study compared teacher revision with peer revision on comprehension and production of relative clauses (RCs) in Iranian EFL students’ writing performance. Data were collected from 109 Iranian intermediate language learners studying at Imam Khomeini International University and Kharazmi University. After being homogenized by taking Michigan Test of English Language Proficiency (MTELP), they were divided into three groups (teacher revision, peer revision, and control). They all sat for the pretest. Then, the students in teacher revision and peer revision groups underwent eight treatment sessions, practicing teacher revision and peer revision respectively. The control group, however, did not receive any treatment. Then, the posttest was administered to all the groups. ANCOVA was employed to compare the performances of the groups. The results indicated that both teacher and peer revision were beneficial to students. However, peer revision led to better comprehension and production of RCs. The findings may carry implications for language educators, language learners, and language teachers.

The effect of different concentrations of mallow (Malva sylvestris) and poppies (Papaver rhoeas) leaves and walnut (Juglanse regia) green husks extracts were investigated on hatching and mortality of second-stage juveniles of Meloidogyne javanica under experimental conditions. In J2 mortality test, the extracts were used in 14 levels of mallow (0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.75, 1, 1.25, 1.5 and 2%), 7 levels of poppy (0.5, 1.5, 2, 2.5, 3, 3.5 and 4%) and 8 levels of walnut green husks (1, 2, 3, 3.5, 4, 4.5, 5 and 6%). In three independent tests, controlling effect of 100 milliliters of the obtained lethal concentrations (LC20, LC50 and LC80) of each extracts (0.36, 0.58 and 0.94% for mallow; 2.3, 2.9 and 3.8% forpoppies; 2.68, 4.07 and 5.18% for walnut green husks) on M. javanica were evaluated under the greenhouse condition. According to the results of this study, the nematicidal effect of all tested extracts against M. javanica was proved under laboratory conditions. In greenhouse trials, any increase in the concentration of plant extracts significantly improved the growth indices of tomato plants and also the obtained LC80of mallow, poppy and walnut green husks extracts significantly reduced the number of galls by 59, 71 and 74%, respectively, and the reproduction factor by 56.7, 85 and 87%, respectively, when compared to the control.

By announcing the general policies of the resistance economy by the Supreme Leader and his emphasis on activating all human and scientific capital of the country in order to have strong human resources, and a resolute resolve to make progress, once again the importance of paying attention to the human resources of the country became evident at this time. Meanwhile, organizational indifference is one of the most important issues of human resources which bind most of the government organizations in the country and making it difficult to achieve the goals of a resistance economy. In this research, the researchers intend to investigate the causes and roots of the emergence of organizational indifference based on different perspectives, by using interpretive structural modeling method to explain organizational indifference behavior. For this purpose, by analyzing and reviewing the literature, and by means of content analysis and semi-structured interviews with experts and specialists, effective factors in explaining organizational indifference behavior were identified. Initial results resulted in the extraction of 280 open codes, 60 basic contents and 10 organizing contents in explaining organizational indifference behavior. Subsequently, with the application of interpretive structural modeling, these factors were classified into five categories. In the following, after determining the levels of each of the factors and also considering the matrix of final availability, the final model of organizational indifference for human resources was drawn.

Seed deterioration as an irreversible physiological phenomenon, have significant effect on seed quality. Increasing and maintaining of seed quality by using methods such as biopriming is important. For this reason a three-factors experiment was conducted on one linseed cultivar (Norman) based on randomized completely design with four replications, in laboratory of Seed Science and Technology, college of agriculture, Yasouj university in 2015. Factors were includeing storage period (31, 53, 93 and 130 days); storage condition in two combinations of storage temperature (°C) and seed moisture content (%) (moderate condition (15°C/17) and severe condition (35°C/9%); and biopriming with two strains of Thrichoderma harzanium (T36 and T40) and two strains of Pseudomonas fluorescens (CHA0 and P.F(2)) and non-priming (control). Seeds inoculation by bacterial and fungal suspension was done before or after storage. During storage period of 31 to 130 days, germination parameters and peroxidase enzyme activity decreased and electrolyte leakage, soluble sugar content and malondialdehyde content increased. During 31 and 53 days of storage under moderate condition biopriming with T40, P.F2 and CHA0 have increased germination indices compared to non-primed seeds. In 93 and 130 days storage treatments, priming with T40 significantly affected germination compared to other treatments. On the basis of current study using effective biological treatments in improving germination and maintaining Flax seed quality under different storage condition is suggested.

Root-knot nematodes are one of the most important plant parasitic nematodes. The damage of these nematodes on tomatoes is estimated about 20-30%. One of the latest methods for controlling pests and plant diseases is application of organic products and use of natural ingredients with microbial and herbal origin. In order to reduce the damage of root-knot nematode in tomato plants, the nematicidal effects of aqueous extract of oak (Quercus branti L.) were evaluated on root-knot nematode, Meloidogyne javanica in vitro as well as in greenhouse conditions. An experiment was conducted in a completely randomized design. The treatments consisted of 1- plant parts (leaf and fruit) 2- plant extracts (at five concentrations, 1%, 2%, 3%, 5% and 7% for laboratory tests, and 0.05%, 0.1%, 0.15%, 0.25% and 0.35% (g dry powder in 100 grams of soil) for greenhouse experiments). Extracts of different parts of both tested plants caused maximum mortality of the second stage larvae, at the rates of 5% and 7%. Leaf and fruit extract at the rate of 7% caused 100% larval mortality. In case of reproduction factor, none of treatments had hazardous effect on plant growth including root and shoot length, fresh and dry weight. Between all treatments, the best treatment was identified at the rate of 0.35%, which was effective enough against nematode and also had no harmful effect on the tested plant.
