Some experiments with the aim to identify insects feeding on the dodder Cuscuta campestris Yuncke as an important parasitic flowering plant, resulted in the discovery of two new potential biological control agents namely Oxycarenus hyalinipennis (Costa, 1843) (Hemiptera: Lygaeidae) and Aphis fabae Scopoli, 1763 (Hemiptera: Aphididae). Oxycarenus hyalinipennis was observed feeding extensively on dodder seed capsules that were parasitizing Christ's thorn Jujube tree Ziziphus spina-christi (L.) Wild. Also aphid feeding caused severe damage to the dodder vine wraps on native hopbush Dodonaea viscosa (L.) Jacq. This is the first report of O. hyalinipennis and A. fabae feeding on C. campestris highlighting their potential as a biological control agent in Iran.

Grammatical markers are those types of words by which the function of other words in the sentence is recognized. At first glance, grammatical words have no task except linking other words together, and are not amongst words towards which poets have any special concern. But studying them in poetry shows that they have various artistic functions and can be counted as effective tools by poet for constructing the language of his poem. This study aims at analyzing the aesthetic functions of grammatical words in contemporary poetry, and with an inductive method delineates that they are as essential as other words in the structure of poetic language and the effectiveness and foregrounding of speech. This category words influence the foregrounding of poetry both semantically and syntactically, and are employed as instruments for the emphasizing and foregrounding meaning, emotion and thought, and also as elements in creating music, irregularity, building of new linguistic forms, creativity and innovation in the field of poetry. Beginning or ending poems or lines of poems by some of these conjunctions, creative clustering or omitting of these words, and emphasizing the meaning by the proper employment of these words in the syntactic context of the poems are examples of the most significant aesthetic functions of grammatical markers in contemporary poetry.

Aims: Most parts of the pastoralist's livelihood depend on income from livestock in the rangelands, but drought in rangelands has negative impacts on the ecosystem, cycle of nomadic pastoralists, livestock production, and their family's living. Recognizing the signs of drought effects in the nomadic environment can play a significant role in rangeland management. The present study was conducted to identify and investigate drought signs in Gonbad-e Kavous County, Golestan Province, Iran.
Materials & Methods: The study's statistical population consisted of 183 nomadic pastoralists in 10 customary systems, 100 of them were sampled and classified by random method. The data gathering tool was a researcher-made questionnaire. Drought signs were investigated in three dimensions: vegetation, soil, livestock, and herd. In order to ensure the validity of the questionnaire, the views of the experts of the Natural Resources Bureau and Cronbach's alpha method were used for more reliability with an average of 0.717.
Findings: The results showed that nomadic pastoralists assessed three factors forage quality degradation, increasing bare land, and livestock production as the most important indicators of drought effects in pastureland. Findings indicate a positive and significant relationship between the pastoralist's viewpoints about the signs of drought effect in the pasture with the variable of the people who depend on them. The results showed a significant difference between respondents' views on gender and education level in the context of drought effects.

The idea of predestination and free will and the role or lack of fate in life events have always existed in the minds of thinkers and have been reflected in different ways and works. The common people have been involved with these two dimensions, and its manifestations have entered the folklore and native literature of a land and region. The purpose of this article was to examine the deterministic view in the folktales of Hormozghan province, from perspectives such as the roots and reasons for the spread of this idea, those quarreling fate, the degree of fit between fate and an individual's competence, the issues supported by fate, among others. Reasons such as the inability of the populace to make changes and achieve their desired goals, religious and historical roots and the remnants of some Zurvanism beliefs are among the factors that lead to this idea. Emphasizing the role of fate is one of the weak points of plot in these stories and the weakening of rational actions. There is no logical connection in many cases in terms of the proportionality of the power of fate and a person's ability. In these stories, fate is present as an active and powerful fictional character or as a judge who regulates their actions and results so that, in the end, the supported character is defeated against powerful quarrelers such as the king. From the thematic point of view, the most frequent topic supported by fate is the marriage of two characters.

This study was performed to determine the identification (barcoding) using cytochrome oxidase gene of common carp, between three provinces of Golestan, Mazandaran and Gilan (respectively in Gomishan, Tajan and Kiashahr) in 2011. The results of sequencing showed that all samples from the three regions had a genetic distance less than 2%, so all samples were from the same species. The results of sequencing 30 tail samples of carp species on the southern shores of the Caspian Sea showed that all samples are of the same species and their genetic distance does not reach at least 2%. Therefore, all carp samples of the three provinces are of the same species and have the same type of barcode. In the study of nucleotide and haplotypic distance, Gomishan region was 10.75000, 1 and Kiashahr region were 3.200 and 0.9333, respectively. In the study of nucleotide diversity between the two regions, 0.01978 and the average nucleotide difference was 12.187. Haplotypic diversity in Gomishan region was 38.095 and in Kiashahr region was 23.809%. Out of 13 haplotypes, Gomishan region with 8 haplotypes (61.53%) and Kiashahr region with 5 haplotypes (38.46%) had the lowest haplotypes.The results of this study show that there is a significant difference between carp samples in Gomishan and Kiashahr regions in terms of nucleotide and haplotypic diversity (P <0.05).

Integrated application of compatible methods is the most reliable strategy for sustainable management of phytophagous pests in different agroecosystems. In the current study, parasitism parameters of Trichogramma brassicae Bezdenko were determined on eggs of Tuta absoluta (Meyrick) reared on a susceptible "Infinity" and a resistant "Goldy" tomato cultivar. All experiments were carried out under laboratory conditions at 25 ± 1 ^°C, 65 ± 5% RH, and a photoperiod of 16:8 (L:D) h. Our results showed that the maximum number of parasitized hosts per parasitoid was 25.94 and 23 eggs in "Goldy" and "Infinity" cultivars, respectively. The cultivars tested had no significant effects on the net parasitism rate (C₀), and the values of this parameter were 7.87 and 6.67 hosts on the mentioned cultivars, respectively. Similarly, the cultivar impact on the finite (ω ) and stable parasitism rates (ψ ) of T. brassicae was not significant. The parasitoid needed approximately one egg host to produce an egg on both cultivars for the simple reason that this parasitoid nearly always lays one egg in each host. In other words, the transformation rate (Q_p) of the parasitoid on the "Goldy" did not differ from that estimated on the "Infinity". Our findings revealed that the resistant tomato cultivar, "Goldy", did not compromise T. brassicae-based biocontrol of T. absoluta. Therefore, these two control procedures could be combined for the integrated management of this pest.

A crossbreeding experiment involving four Iranian fat-tailed sheep breeds, namely Kurdi (K), Chaal (C), Afshari (A) and Sanjabi (S) was carried out to determine the ram breed effects on productivity of Kurdi fat-tailed ewes (K) under extensive production system. A total of 475 Kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure Kurdi, KK, (116 lambs), Afshari × Kurdi, AK, (113 lambs), Chaal × Kurdi, CK, (115 lambs) and Sanjabi × Kurdi crossbreds, SK, (110 lambs). Ram breed had a significant influence on early growth traits of the lambs (P < 0.01). The lambs sired by C rams were significantly heavier at birth and weaning than the other lambs (P < 0.05). Weight at 180 days of age (W180) in crossbred lambs was significantly higher than that of the purebred lambs (P < 0.05) while there was no significant difference among crossbred lambs for W180. Greasy fleece weight of lambs at first shearing (GFW) was significantly affected by ram breed (P < 0.05). Ram breed significantly influenced the fat-tail measurements of the lambs (P < 0.01). Number of lambs born and number of lambs weaned per ewe lambed or per ewe joined were not significantly influenced by ram breed effect, but the effect of ram breed on litter weight at birth and weaning per ewe lambed or per ewe joined was significant (P < 0.05). In general, ewes mated to Chaal ram had higher productivity than those mated to other ram genetic groups.

The process of alteration, in the manuscripts of famous literary works, is a type of creative reading creating multiple and different versions of a single literary text during the time. From this perspective, the editor or the scribe like reader who is not merely the recipient of the finalized meaning but he is an active agent in building the meaning and even reconstruction of the form (language and vocabulary). However, in the view of the scribes, any change in the original text is indecent. These changes, for many reasons, are the essence of literary reading and in some cases, it is a genetic and interactive process. This research can be review the alternations of the literary texts from a rhetorical view point and based on the reader's reception methodology. For this reason, due to the duplications that are likely to change in them, has been made a rhetorical comparison between the original text and the changes. Attempt to reconstruct the author's intention with corrector, text interaction with the taste of society or person (fusion of horizons), opened or closed text and the desire to develop and complete linguistic and semantic gaps are the most important factors effecting in these changes. The most important aspects of these changes and alternation are creating phonetic and musical symmetries, adorn it to the rhetorical figure, more proportion between vocabulary, the pervasive of meaning of poetry, update of text based on desire and language of the period and escape it from obsolete. Hence, the modified text has gained more popularity and rhetorically than the original text.

This research was carried out to study the antifungal effect of aqueous extract and powder of Pistacia atlantica at 0, 0.5, 1, 2.5 and 5% on the growth of Aspergillus flavus and Aspergillus niger. Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) of the baneh extract and powder was certified against Aspergillus niger and Aspergillus flavus in concentrations of 0.5, 0.4, 0.3, 0.2, 0.1 and 0.05 g /ml were determined by Serial Dilution technique. After preparing lactic cheese samples, a 10 mm piece was placed inside the plate and 3 μl Aspergillus flavus and Aspergillus niger was added to its center. Plates were incubated at 26 ° C for 3 weeks and the zone diameter of mold growth was measured. The results showed that by increasing the storage period, the growth zone diameter of Aspergillus flavus and Aspergillus niger in all of treatments increased. The treatments had a greater effect on the control of Aspergillus flavus mold growth than that of Aspergillus niger in lactic cheese. In mold and yeast counting, the highest count was observed for control treatment and the lowest increase was related to treatment containing 5% extract of Pistacia atlantica. The experimental treatments also significantly affected the sensory properties of the cheese samples. The highest taste scores were for samples containing 0.5 and 1% Pistacia atlantica extract. The samples containing more levels of extract (2.5 and 5 %) were less scored in terms of flavor and taste than those containing powder of Pistacia atlantica. From the findings of this study, it can be concluded that extracts and powder of Pistacia atlantica have an appropriate antifungal activity against Aspergillus niger and Aspergillus flavus, Therefore, they can be used in medical pharmacology, food industries and health affairs as drugs and anti-fungal elements.

Plant essential oils and extracts are the compounds that can inhibit bacterial growth at low concentrations. Also, these materials are mostly strong antioxidants and the presence of these two properties together increases the shelf-life of fish. This study was done to investigate effect of various concentrations of caraway and thyme essences on chemical and microbial quality of common carp fillet. Different concentrations of essential oils (0, 500, 1000 and 2000 mg/l) were added to fish samples and some chemical and oxidation factors, microbial quality and sensory properties of the samples were determined. The results showed the lowest levels of total volatile basic nitrogen was related to 2000 mg/l thyme essential oil (24.6 mg/100 g fillet) and the highest amount of total volatile basic nitrogen were observed in control treatment (75.11 mg/ 100g fillet) at refrigerator temperature. TBA levels in all treatments increased with increasing storage time and at the end of the storage period, except in 500 and 1000 mg/l thyme essences treatments, there was significant difference among all experimental samples (p<0.05). The results showed that various concentrations of essences reduced the total count and Psychrotrophic bacteria compared to the control. At the end of the storage time, treatment of 2000 mg/l caraway essence, 1000 mg/l caraway essence and 2000 mg/l thyme essence had the lower Psychrotrophic bacteria than the other samples. Treatments with 1000 and 2000 mg/l caraway essences in freezing conditions received the most colors score. The highest score of texture was related to 2000 mg/l thyme essential oil at refrigerator temperature. Samples containing 1000 mg/l caraway essence in freezing temperatures had the highest odor score. In general, 1000 and 2000 mg/l concentrations of thyme essence due to acceptance of the organoleptic characteristics from the consumer view as well as reduce microbial growth and chemical factors are recommended.

Studbook information collected from 1988 to 2011 in Jafarabad breeding station of Moghani sheep, north-west of Iran, related to 9,457 lambs were used to study the genetic diversity and to evaluate the effectiveness of an implemented rotational mating scheme using pedigree analysis. Lambs born during 2009-2011 were considered as reference population. Means inbreeding and average coancestry for the reference population were computed as 0.40 and 0.74%, respectively. The mean generation interval was 4.48 years with a longer generation interval on dam-progeny pathways. Average equivalent complete generation, as a measure of pedigree completeness, was 3.37. Effective population sizes were estimated to be 226 and 276 from the individual rate in coancestry and from the individual increase in inbreeding, respectively. Genealogical parameters estimated based on probabilities of gene origin including the effective numbers of founders, the effective numbers of ancestors, the effective numbers of founder genomes (founder genome equivalents) and the effective numbers of non-founder genomes considering the reference population were estimated as 143, 117, 67, and 126, respectively. Approximately, 50% of the total genetic variation was explained by the 43 most influential ancestors, with a maximum individual contribution of 3.27%. The results indicated that although some evidences on bottlenecks and genetic drift during recent years were identified in the studied population, a considerable genetic variability existed in this population due to implementation of an efficient rotational mating scheme for controlling inbreeding.

In the present study, the influence of drying temperature on energy consumption and qualitative characteristics of onion including rehydration capacity, vitamin C content and total phenolic content (TPC) was investigated. Onion slices with 3 mm thickness was dried in a hot air dryer at temperatures 0f 40‒70 °C. Specific energy consumption and energy efficiency were significantly (P < 0.05) improved by increasing temperature and obtained to be in the range of 35.83‒59.33 MJ/kg and 4.01‒6.52%, respectively. Increasing air temperature resulted in significant (p < 0.05) improvement in energy consumption indices. Rehydration capacity in the dried onion samples varied from 4.01% (at drying temperature of 40 °C) to 6.52 (at drying temperature of 70 °C). Vitamin C content in fresh samples was 50.19, and in dried samples varied from 14.92 to 21.38 mg/100 g _{dry matter}. TPC was measured using Foline–Ciocalteu reagent and found that the TPC in fresh onions (389.6 mg GAE/100 _{dry matter}) was significantly (p < 0.05) decreased in the dried samples (212.3‒295.8 mg GAE/100 _{dry matter}). Based on the obtained results, drying of the onions at higher temperatures led to more deterioration in vitamin C content and the TPC.

The aim of this study was to investigate the effect of microencapsulation of probiotic bacteria with sodium alginate/resistant starch and sodium alginate/chitosan by extrusion method on qualitative and rheological properties and viability of bifidobactrium animalis subs lactis in Aloe vera doogh. 10% of aloe vera gel with different concentrations of whey (5, 10 and 15%) and inulin (0.5, 1 and 1.5%) added to probiotic doogh and their effect on the protection of Probiotic bacteria and qualitative properties were evaluated. The results showed that increasing the level of inulin had no significant effect on pH. Increasing the percentage of whey up to 5% had no significant effect on the pH, but increasing more than 5% significantly decreased the pH of the doogh samples during storage period. In terms of sensory properties samples containing 1% inulin and microencapsulated bacteria with sodium alginate/chitosan had highest scores in flavour while lowest score was observed in control treatment (without inulin and whey) and free bacteria. Doogh samples containing 1.5% inulin had the lowest serum separation and the control sample (without inulin and whey) showed the highest serum separation at the end of storage period. In general, samples containing microcapsules had a lower serum separation than samples containing free bacteria. The highest viscosity and consistency coefficients were observed in the doogh samples containing 1.5% inulin. The microencapsulation process increased the apparent viscosity, consistency index and loss modulus and decreased the flow behavior index of the doogh samples. Microencapsulation of probiotic bacteria by sodium alginate / resistant starch and chitosan and use of whey and inulin in doogh samples increased their viability during storage period.

In this study, the effect of various concentrations of date syrup as a sugar substitute in ratios of 0, 50 and 100% on quality characteristics of dairy dessert was evaluated. Properties of dairy dessert such as pH, acidity, rheological properties, sensory properties and viability of probiotics in 5 ˚c were determined. Results showed that by increasing date syrup concentration and amount of probiotic bacteria, pH decreased and as the storage progressed significant trend in the pH was observed for all treatments. Studied treatments had statistically effect on viscosity. Addition of date syrup decreased apparent viscosity, consistency coefficient and increased flow behavior index. The most and lowest viscosity was observed in control (1364.1 mPa.s) and 100% date syrup treatments (599 mPa.s), respectively. Sensory properties were affected by date syrup concentrations. Treatment with 50% date syrup had higher scores than others. The number of viable cells of probiotic bacteria was reduced significantly during storage period. The lowest and highest of viability of probiotic bacterial was observed in 100 and 50 % date syrup treatments, respectively. The results suggest that using of date syrup at concentrations of 50% improve sensory and physical properties and can increase viability of probiotic bacteria of dairy dessert samples.

Nowadays, the food industry is looking for new technologies to increase the shelf life of various products. Furthermore, as consumer's demand for more “healthier” meals (free of conventional chemical preservatives) has increased in the last decade. In this study, edible sago starch coating containing leave extract of Withania Somnifera (0.125 and 0.25 mg/ml, 1 and 2 times MIC, respectively) was applied onto chicken fillet to extend its shelf life at 4 ˚C. Examination of coated chicken fillets showed that active film of sago starch inhibited the microbial load (aerobic bacteria, coliform and Staphylococcus aureus bacteria) of chicken fillets. The results of chemical analysis of chicken fillet also showed that the coated samples had less volatile nitrogen compounds, thiobarbituric acid index and peroxide value than control. In general, the results of this study showed that the edible film produced from sago starch containing Withania Somnifera extract increases the shelf life of chicken fillets.
