Abstract

The elm leaf beetle Xanthogaleruca luteola Müller (Coleoptera: Chrysomelidae), is a serious pest of elm (Ulmus spp.) throughout Iran. In the present study, Lethal and sublethal effects of neem, Achook® containing 0.03% azadirachtin, were assessed on mortality, growth, larval weight and feeding deterrence as well as enzymatic and non-enzymatic activities of third instar larvae of the elm leaf beetle. LC50 and LC30 values of the third instar larvae 48 h post treatment were estimated to be 3.3 and 2.25 ppm respectively. Observations showed higher mortality, increase in larval duration, sterilization of adults, reduction in weight and feeding deterrence after LC30 and LC50 treatments. Biochemical analysis showed changes in the amounts of biochemical components in the treated larvae after 48 h. In the treated larvae, activity level of alanine aminotransferase, alkaline phosphatase, acid phosphatase and α-amylase as enzymatic components and urea and cholesterol as non-enzymatic ones changed significantly in LC50 and LC30 treatments. Aspartate aminotransferase, lactate dehydrogenase, protein, glycogen, and glucose levels decreased in these treatments. The activity level of detoxifying enzymes such as esterase A, esterase B and glutathione S-transferase were significantly affected. Hence, neem is suggested as a safe product that may have the potential for use as a bioinsecticide in integrated pest management of urbanelms where use of chemical insecticides are discouraged.

Abstract

Mulberry pyralid, Glyphodes pyloalis Walker is an important pest on mulberry. The essential oil of Rosemary Rosemarinus officinalis L. (Lamiales: Lamiaceae) has been investigated on toxicity and physiological characteristics of this moth under controlled conditions. The major compounds of the oil were analyzed as 1, 8 Cineol (20.021%), Borneol (7.17%), Camphor (6.541%), Geraniol (6.281%), Camphene (5.623%), Linalool (4.993%) Alpha fenchyl acetate (4.222%) and Verbenone (4.147%). Lethal and sublethal concentrations (LC10, LC30 and LC50) were estimated 0.77%, 1.18% and 1.59% (v/v) respectively. The essential oil affected the nutritional indices of fourth instar larvae of G. pyloalis. efficiency of conversion of ingested food (ECI), efficiency of conversion of digested food (ECD), relative consumption rate (RCR) and relative growth rate (RGR) were reduced in larvae treated with R. officinalis essential oil while approximate digestibility (AD) in treated larvae was significantly increased compared with the control. The essential oil affected the insect’s some key metabolic compounds like; lipid, protein and carbohydrates. Similarly this effect was also significant in the activities of certain key enzymes like; alpha- amylase, lipase, protease, glutathione-s-transferase and esterases.

Abstract This article examines the relation of national pride with personality (authoritism and democratic), efficacy (political efficacy and social efficacy) and political knowledge. The aim is to explain the meaning of national pride as the, positive feeling of people to their country, and Conceptualize this in two types; nationalism and patriotism. The methodology of this study is social survey. Samples of study have been selected from among all residents over 15 years old in the fourteen sectors of Isfahan city (Iran). According to the 2006 Census, the size of this population is around 1248754 people. In the next step, by applying the Kokran Formula and quota sampling, 384 people were selected and examined as samples of the study. The findings showed that nationalism has positive correlation with authoritism personality, social efficacy. It and political efficacy also has negative correlation with democratic personality and political knowledge. Patriotism has positive correlation with democratic personality, social efficacy and political knowledge. In addition, it has negative correlation with authoritism personality and political efficacy.

Abstract

Background: Human papillomavirus (HPV) is one of the most common causes of sexually transmitted disease (STD) in humans. HPV is associated with gynecologic malignancy and cervical cancer among women worldwide. In the current study we sought to determine the prevalence rate of HPV in Iranian women identified with cervical infections.
Materials and Methods:  Prevalence rate of HPV in Iran was investigated from 2000-2016 using several databases including Medline, Web of Science, Embase, Google Scholar, Iranmedex, and Scientific Information Database. Statistical analysis was performed by Comprehensive Meta-Analysis (V2.2, Biostat) software. Random effects models were used by taking into account the possibility of the heterogeneity between the studies, which was tested through the Cochran’s Q-statistic.
Results: The meta-analyses showed that the prevalence rate of HPV infections was 38.6 % (95% CI, 27.9-50.5) among Iranian women with cervical infections. The further stratified analyses indicated that the prevalence rate of HPV was higher in the studies conducted during the 2000-2008 years.
Conclusion: The results of the present study underscore the need for further enforcement of STD control strategies in Iran. Establishing advanced diagnostic facilities for HPV, vaccination of high risk groups, and continuous monitoring of HPV are recommended for HPV prevention and control.

Abstract

Searching efficiency and handling time are two major components of functional response and are usually used to evaluate effectiveness of natural enemies. The effect of different foraging periods on the functional response of larval Aphidoletes aphidimyza (Rondani) (Dip.: Cecidomyiidae) feeding on third instar nymphs of Aphis craccivora was studied. The experiment was conducted in terms of time-specific (1, 2, 4, 6,12, 24 h.) functional response to varying densities (5, 10, 20, 40, 60 and 80) of third instar nymphs of A.craccivora at 23 ± 1 °C, 70 ± 5% of R.H., and a photoperiod of 16:8 h (L: D). Parameter estimates for logistic regressions showed a type II functional response for 4 day-old larvae of the predator at different foraging periods to varying densities of A. craccivora. The estimated searching efficiency (a') and handling times (Th), varied with foraging periods. The searching efficiency showed a decreasing trend as the foraging periods increased. The estimated maximum rates of predation (T/Th) for the 4-day old larvae were directly related to the foraging periods increase but handling times (Th), showed a decelerating trend. In conclusion it was found that searching efficiency was a variable parameter in different foraging periods of A. aphidimyza and was lowest at the foraging periods of 24 h. It was also suggested that A. aphidimyza with type II functional response in all foraging periods, could be considered as a highly effective biological agent in suppressing A. craccivora population.

Abstract

The impact of climatic variations on basal area growth of basswood (BA) (Tilia americana L.), American beech (BE) (Fagus grandifolia Enrh.), bitternut hickory (BH) (Caria cordiformis (Wang.) K. Koch), largetooth aspen (LA) (Populus grandidentata Michx.), red maple (RM) (Acer rubrum L.), red oak (RO) (Quercus rubra L.), sugar maple (SM) (Acer saccharum Marsh.), and white ash (WA) (Fraxinus americana L.) was studied in a southern province of Quebec, Canada (45o 25 ’ N, 73 o 57 ’ W). In total, forty-eight climatic variations of precipitation (P) (13 variables), temperature (T) (13 variables), heat index (H), (11 variables), and evapotranspiration (11 variables) from the current (C) and past three years (P1, P2, & P3) were tested in regression models to find the best model of the relationship between those independent variables and the last ten years (1985-1994) of basal area growth of the species. Simple individual linear and second degree, mixed, and combination of multiple regression models were used to develop the best regression model for each tree species, separately. The best models explained 79% , 80% , 99% , 91% , 71%, 99% , 49% , and 98% of the total variance of the growth in BA, BE, BH, LA, RM, RO, SM and WA, respectively. The growth in BH, LA, RM, RO, SM, and WA were more associated with the previous year’s climatic variations rather than the current year’s. Bitternut hickory, LA, RM, SM, and WA growth were more related to the first year rather than the second or third preceding year variables. The June heat index of the third previous year of variables explained only 7% of the growth of white ash. It was concluded that the impact of climatic variables on tree growth may vary and may depend on the species and other unknown variables. Also, the results suggested that the first and second previous climatic variables have an important role on the growth of some species. American beech, BH, RO, and WA seem to be a good species to use for the study in dendrochronological and dendroclimatological studies.

Abstract

Superabsorbent hydrogel is a three-dimensional hydrophilic polymer that can absorb and store large amounts of water and aqueous solutions. Among various polymers, the chitosan as a biodegradable and non-toxic polymer has been widely used to fabricate superabsorbent hydrogels. In this research, a nanohydrogel composed of chitosan, acrylic acid and silver nanoparticles was synthesized by radical polymerization at 60 Co. Swelling properties of chitosan/nanosilver/acrylic acid hydrogel were studied and then this hydrogel was treated under  ultrasonication. Finally, this hydrogel was coated on paper samples with 0, 1, 1.5 and 2 w % of hydrogel. FTIR spectroscopy was used to determine the functional groups and dynamic light scattering method (DLS) was applied to identify the size of hydrogel’s nano and microparticles The images of scanning electron microscopy (SEM) showed a hydrogel coating on paper and water stress tests revealed that adding 0% to 1.5 w% of nanohydrogels to the paper surface increased its water absorption from 64.3% to 95.5%. Other worthwhile fact was that that the addition of silver nanoparticles effectively facilitated the formation of a three-dimensional hydrogel structure and increased the water swelling in nanohydrogel from 130 ± 10 g / g to 232 ± 7 g / g.

Abstract

The Mediterranean flour moth, Ephestia kuehniella Zeller, is one of the major pests in stored products worldwide. Several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (IGRs). In the present study, growth regulating activity and hematological effects of pyriproxifen and methoxyfenozide were evaluated on E. kuehniella larvae. Effects of the insecticides were evaluated under laboratory conditions set at 26 ± 1 °C and 75% RH. Findings indicated that inhibition dose for fifty percent of population (ID50) was equal to 0.16 µg/mg larvae for pyriproxifen and 0.4 µg/mg larvae for methoxyfenozide, showing the considerable growth regulating effect on two-day-old fifth instar larvae. Then, influence of estimated doses were investigated on the insect hemocytes including total hemocyte count (THC) and differential hemocyte count (DHC). THC and the proportion of plasmatocytes were decreased as pyriproxifen doses increased, while, the granulocytes level was increased. In contrast, application of sublethal doses of methoxyfenozide caused a conciderable increase in THC and the plasmatocytes density, while, number of granulocytes was decreased. Since the total number of hemocytes and the proportion of plasmatocytes are very crucial in immune responses of insects, pyriproxifen could be used as an immunosuppressive pesticide in integrated control of E. kuehniella.

Abstract

As the former of the structure of story, language is significantly important in the structural analysis. Based on this viewpoint, language structure and the way it is used, as well as the connection between the aesthetics and ultra-linguistics are specifying its type in relation with the general concept of the literary work. Also the epic language, as the basic foundation of these texts, prospers structural potentialities like word usability, syntactic of utterance, and useful intonation proper with the epical atmosphere and feelings in different levels such as vocal, semantical, etc.
In oral literature, along with having stories from a simple and pure language, presence of rhapsodists and elocutionists and their interference and distort together with new elements ingression in the form of “Scrolls” compilation have increased more and more the use of epical language capacities linked to the main context of scrolls. The “Haft Lashkar” (the Seven Corps) is also one of the Rhapsodists’ Comprehensive Scrolls (RCS) during the Qajarid era of which the time of writing goes back to the year 1292 (Lunar Hijri) (almost 1871 A.D.), and it is originally the name of one of the famous rhapsodic battle-narrations, which was applied to one of the RCSs due to its fame. 
Therefore, considering the general concept of the currently discussed work in this paper, its epical structure has been analyzed and checked from two levels:, vocal and Syntactic levels. Using bursting-obstructive phonemes and long Syllable structures along with high-frequency short vowels in the vocal level has made the epical atmosphere and feeling more tangible for the readers. In syntactical structure of the utterance, the priority of the verb and displacing the other elements of the sentence, associating the elements of the same function, as well as creating areas via the rhapsodist’s exploitation from the drama tune, the skills of discourse-movement and the oral techniques are all considered as the elements of forming an epical language. Moreover, the musical characteristics of the oral narration like the height of the sound, using long and loud vowels at the end of the questions and vocative sentences have led to the enhancement of the rising voice of the discourse and eventually, the epical language.

Abstract

Aims: The main goal of the upcoming research is to explain the principles and spatial qualities of campuses based on the environmental preferences of female students.
Methods The nature of the research is qualitative and exploratory based on the methodology of content analysis and semi-structured in-depth interviews with a total of 40 female students of the faculties of literature and humanities and basic sciences in each of the two studied universities of Tehran and Shahid beheshti is done.
Findings: According to the narrative of female students, eight criteria of urban location, university campus structure plan, faculty architecture plan, likeability, university brand, attention to the dignity and rights of female students, the attractiveness of university activities and events, and the importance of hangout in the university are among the environmental qualities. It is effective in improving the presence of female students in university campuses.
Conclusion: Based on the environmental preferences of women, in addition to physical factors, non-physical factors are also effective in the presence of women in university campuses. In addition, the space may have a suitable physical quality, but it is gendered in a way that gives the woman the feeling of being subjugated and under control. For this purpose, the physical qualities of university campuses are necessary and not sufficient to promote the presence of girls.

Abstract

Culture filtrates (CF) of two species of the nematophagous fungi, Arthrobotrys oligospora and Arthrobotrys conoidesat three concentrations (25%, 50% and 100%) of stock, were tested on the mortality of second stage juveniles (J2) and egg hatching rate of Meloidogyne incognita and Meloidogyne javanica. Results showed that the percent juvenile mortality was directly proportional to concentration of the filtrates. Egg hatching rate of these nematodes was inversely affected by increasing concentrations. Also CFs had various impacts on the mortality of J2 and egg hatching rate. In case of M. incognita maximum J2 mortality (28.98%) occurred after 24 hours of exposure to A. conoides filtrate at concentration of 100%. The minimum toxicity (12.5% J2 mortality) was recorded for A. oligospora at 25% filtrate concentration. At the same time, the highest rate of J2 mortality of M. javanica (19.18%) belonged to the 100% concentration of A. conoides, while minimum toxicity belonged to 25% concentration of A. oligospora causing 9.09% mortality. Maximum egg hatching rate for M. incognita (30.75%) belonged to control and minimum hatching rate (1.25%) belonged to 100% concentration of A. conoides. The highest hatching rate of M. javanica (36.25%)belonged to control and minimum hatching rate (1.25%) occurred at 100% concentration of A. conoides.

Abstract

Feeding performance of the green oak leaf roller, Tortrix viridana (Linnaeus) was determined on three host plants including Quercus libani Oliv, Quercus infectoria Oliv, and Quercus branti Lindl, under laboratory conditions. Mean total leaf weight consumed by larvae was the highest on Q. branti (0.31 g) and the lowest on Q. libani (0.14 g).The feeding index was the highest on Q. libani while the other two host plants were not significantly different. Significant relationships were found between amount of consumed leaf tissues and resulting pupal weight, on all host plants. Larval and pupal mortality were not significantly different on host plants. Findings indicated that the feeding index could be a key factor to assess performance of T. viridana on Quercus species.

Abstract

A Castanea crenata agglutinin (abbreviated as CCA) was extracted and purified from bitter apple, Citrullus colocynthis L., to determine its effects on the demographic parameters of Apomyelois ceratoniae Zeller. Two groups of first larval instars were reared on an artificial diet containing 2% (w/w) of CCA and control diets until emergence of adults. Two Sex MS-chart life table software was used to analyze data and calculate life table parameters. Developmental times of larvae in control and CCA dietsshowed statistical differences for male, female except for third and fourth larval instars. It was found that A. ceratoniae larvaefed on control had a survival of 18 days but individuals fed on CCA diet survived for 12 days. The highest fecundity values of individuals fed on control and CCA diets were obtained at the age of 30 and 27 days, respectively. Adult longevity, pre-oviposition period, oviposition period and mean fecundity of A. ceratoniae fed on control were higher than those of individuals fed on CCA diet. The probabilities of a newborn egg surviving to age 28 days were 0.42 and 0.3 for control and CCA, respectively. Each female started egg laying on day 22 for control and 25 for CCA. Life expectancies of a newly laid egg were 29 days for control and 26 days for CCA treatment. Life table parameters except for mean generation time showed statistical differences between control and CCA treatments. These results demonstrated the negative effects of CCA on life table parameters of A. ceratoniae that might lead to a promising and alternative way to suppress population increase and damage caused by A. ceratoniae.

Abstract

Plant fibrous suspensions require electrostatically cationic polymers to provide proper and strong structures during papermaking. The charge bearing naturally and synthetically polymers (Polyelectrolytes), are considered as the most chemicals used in cellulosic products mills, due to improvement in the fibrous suspension and network properties. For this, cationic acrylamide polymer (CPAM) and anionic nano cellulose (ANC) were added individually and in combination forms into the fibrous suspension recycled from brown packaging papers. Compared to the blank sample without any the polymeric additive, the polymeric contained suspensions and networks revealed improvements in fibrous suspension properties; i.e., retention, freeness and the solid materials loss during the network formation; and in the fibrous dried network, include density, tensile and burst strengths. Individually application of each CPAM and ANC increased the suspension retention (productivity) as 8% and 2%, resp. Fibrous suspension freeness and loss materials content continuously increased and decreased up to 47%, respectively that could provide significant technologically and economically benefits. Paper density (+5%), tensile (+17%) and burst (+27%) properties improved drastically compared to the blank. But, tear strength of fibrous network decreased (-4%) which could be attributed to the network higher fines contents and retention, originated from the acrylamide polyelectrolyte flocculation effect. Individually application of ANC also enhanced suspension retention, network density, tensile and burst strengths and declined network tear strength with lesser suspension freeness and loss. Anionic nature, high specific surface area and huge hydrogen bonding potential of ANC are the main reasons of the obtained results. ANC post addition to CPAM contained suspension resulted in tear reduction, but higher suspension retention and freeness, together with higher density, tensile and burst strength of cellulosic network.

Abstract

Haft Lashkar is one of the examples of comprehensive scroll written by an anonymous narrator in the Qajar era in 1292 BC. This title has been allocated to the name of one of the famous battle - narration due to its reputation and popularity as scrolls comprehensive.
Narrative aspect of the text is the prevalent factor of relationship between literature and drama. Imitating the movements of individual states by the narrator will orient the text toward the dramatic storytelling. In this case, narrator’s structural- subjective manipulation in the text of comprehensive scroll, in addition to explain the position of his/her, prepares the way to special narrative techniques in order to increase dramatic content of the work.
Based on Gérard Genette theory, in the present study narrative features of comprehensive scroll are examined in order to orient the dramatic content. Accordingly, the structure of narration in narration (Trans-narration), besides other narrative properties like order, voice or mood in the form of retrospective or prospective, focalization in narration and the relationship between focus and omniscient narrator are among the important narrative aspects of the present work which have shaped the orientation of dramatic text.

Abstract

Citrus swallow tail butterfly, Papilio demoleus L. is a pest of citrus in many parts of the world. We examined the effect of four different citrus hosts including Citrus sinensis (L.) (Tarocco and Valencia) Citrus limon (L.) (Eureka), and Citrus paradisi Macfad. (Shambarg) on its life table parameters and biological characteristics at 24 ± 1 °C, 75 ± 5% RH and a photoperiod of 16: 8 h (L: D). The developmental time of immature stages was longest onC. sinensis (Tarocco) (12.3 ± SE days).The intrinsic rate of natural increase was significantly affected by variouscitrus, being the highest on C. sinensis (Tarocco) (0.099 day-1) and lowest on C. sinensis (Valencia) (0.011 day-1).The highest and lowest finite rates of increase were observed onC. sinensis(Tarocco) 1.10 andC. sinensis(Valencia)1.01, respectively.The highest gross reproductive rate and the lowest mean generation time were observed on C. sinensis (Tarocco) and C. sinensis. (Valencia), respectively. The findings indicated that C. sinensis (Tarocco) appeared to be the most susceptible host to P. demoleus among the tested varieties. The results of this and similar studies in the future on other hosts may be considered as a basis for finding resistant host/hosts in monitoring this pest.

Abstract

In order to identify plant-parasitic nematodes of eastern forests in Guilan province, soil and root samples were collected and the extracted nematodes were studied based on morphological and morphometric characters. Twenty eight species of plant parasitic nematodes were identified. A population of the genus Hoplotylus was recovered and identified as H. femina. The identification was also verified by partial sequencing of the large subunit ribosomal DNA (rDNA). In addition, two populations of the genus Malenchus were also recovered and based on morphological and morphometric characteristics were identified as M. solovjovae and M. acarayensis. The two species Hoplotylus femina and Malenchus solovjovae are new records for Iran.

Abstract

One of the very consequences of language contacts is the presence of loanwords in a language. A great number of linguistic researches have focused on loanword studies through sociolinguistic approaches. In case of literary texts, the frequent and conscious use of loanwords reflects the style and the implicated purposes of the author which must definitely be transferred in translation. The present study aims to investigate the role of loanwords in literary texts, and their representations in translations. To this end, 148 loanwords were extracted from the American novel, Funny in Farsi by Firoozeh Dumas, then their representations in the Persian translation were studied considering three variables: the donor language, the semantic fields of loanwords and the translation strategies. The results revealed that ‘equivalence’ and ‘definition’ were the priorities of the translator among the translation strategies, and this has led to lose some cultural aspects of the literary text in translation.
