Abstract
The larvae of a moth feeding on the citrus flowers specifically on, Citrus limon, were found in greenhouses in Mazandaran province (north of Iran) in April 2024. Based on the habitat preference, and the morphological features, larvae and pupae were identified as Prays citri (Millière, 1873) (Lepidoptera: Praydidae). This species was listed among the foreign quarantine pests of the country, according to the guide list for monitoring and tracking quarantine agents of Iran on 21 June 2024. It is one of the most harmful pests of citrus plants especially lemon, which is spreading rapidly and creepily in all areas in the world. Our recent evidence revealed the existence of this pest in a moderately wide area of the Iranian northern lemon greenhouses. Background information for a reliable identification of both adults and larvae, the taxonomic history, origin, distribution, host plants, damage, and management practices of the pest are also discussed. The occurrence of this pest is a warning for Iranian citrus orchards indicating a potential risk of its spread, particularly to the southern regions of the country.

Abstract
Some Biochemical properties of silver carp surimi prepared by application of acid-alkali aided methods were investigated and compared to that of derived by conventional method. In terms of total protein solubility and recovery, lipid reduction, and total pigment extractability and myoglobin removal there was a significant (P<0.05) difference among the treatments. Acid-aided method showed the most efficiency to recover more proteins (86.2%) in comparison to the alkaline-aided (79.8%) and conventional (76.7%) methods. The lipid reduction percentage was recorded as 43.6%, 58.4% and 72.3% for the conventional method, and acid-alkali aided methods, respectively. In terms of total pigment removal, the conventional method showed higher efficiency (P<0.05) compared to the pH-shifting methods. Conversely, fish protein solubilisation by acid-alkali aided techniques was more efficient (P<0.05) compared to the conventional method of making surimi. In conclusion, pH-shifting techniques were superior in comparison with the conventional method in order to recover more functional proteins and to efficiently reduce the lipid and myoglobin content of resultant fish protein isolate.

Abstract
Aim: Level of physical activity as key determinant of healthy lifestyle is less than what is required in individuals particularly women. Applying theories of behavioral change about complex behaviors such as physical activity leads to identify effective factors and their relations. The aim of this study was to determine predictors of exercise behavior based on developed Theory of Planned Behavior with planning constructs in military personnel’s wives. Methods: We performed this cross-sectional study on 150 military personnel’s spouses residing in organizational houses, in Tehran, Iran in 2013. The participants were randomly selected with multi-stage cluster sampling. The validity and reliability of developed scale were evaluated before conducting the path analysis. Data were analyzed using SPSS.16 and LISREL8.8. Finding: The developed model predicted 48, 11, 12 and 35 percent of the variance in intention, action planning, coping planning and behavior, respectively. Subjective norms (Beta=0.35, p<0.01) and perceived behavioral control (Beta=0.28, p<0.01) were the predictors of intention. Determinants of behavior included action planning (Beta=0.40, p<0.01), coping planning (Beta=0.39, p<0.01), intention (Beta=0.23, p<0.01) and subjective norms (Beta=0.08, p<0.01). Instrumental and affective attitude had no significant path coefficient to dependent variables. The path of perceived behavioral control to behavior was non-significant. The developed theory fitted to data better than the original theory. Conclusion: This research demonstrated relative weights and relationships of Theory of Planned Behavior constructs with action and coping planning in physical activity behavior of military staffs' spouses. It is essential to consider these effective factors in designing of health education programs.

Abstract
Aim: Physical inactivity, as the leading risk factor for death, is more common among women than men. Despite the effective role of extended Theory of Planned Behavior (TPB) with planning to promote exercise behavior, there is no Iranian standard scale in this regard. This research evaluated psychometric characteristics of the expanded TPB-based questionnaire regarding to the physical activity of military staff’s spouses in Tehran. Methods: Content, face, construct validity and reliability (internal consistency and stability) of this scale was assessed. A cross-sectional survey was conducted among 200 women, who were living in organizational houses, in Tehran, Iran in 2014, in order to do exploratory factor analysis (EFA).The participants were chosen with multi-stage cluster random sampling. EFA was performed applying the principal component analysis and Varimax rotation. Data were analyzed using SPSS. v16. Findings: Content validity index, content validity ratio and impact score of the extended TPB scale were 0.8-0.97, 0.78-0.98 and 4.5-4.8, respectively. An eight-factor structure was extracted as a result of the EFA and accounted for 76.33% of the variance. The calculated KMO was 0.72 and the Bartlett’s test of sphericity was significant (P<0.001). Eight constructs consisted of behavior, affective attitude, subjective norms, perceived behavioral control, coping planning, instrumental attitude, intention and action planning. Cronbach’s alpha value (0.83-0.97) and the intraclass correlation coefficient (0.63-0.91) demonstrated satisfying reliability for the subscales. Conclusion: Validity and reliability of the first developed TPB-directed scale with planning about women's exercise perceptions and behavior in Iran was appraised and approved in this study. This instrument can be utilized by other health researchers.

Abstract
Aim: The objective of this study was to determine the relationship between chronic mechanical low back pain and work-related risky behaviors of nurses at hospitals in Tehran.
Methods: In order to determine the relationship between chronic mechanical low back pain and work-related risky behaviors of nurses, a cross-sectional was conducted among nurses in general hospitals in Tehran- Iran from April 17, 2014 to July 16, 2014. Five hundred eligible nurses, who were working in the different wards of under study hospitals, were included in this study. A researcher- designed 50 - item questionnaire was used to collect data. The Cronbach’s alpha coefficient (alpha=0.91), and test-retest evaluation (ICC=0.94) of the scale confirmed reliability of the questionnaire. Data were analyzed using SPSS.v16 through descriptive and analytic tests. P-value < 0.05 was considered significant in both analyses. Findings: In total, five hundred nurses with mean age of 37.71+ 6.75 years took part in the study. 168 nurses (33.6%) were male and 332 nurses were (64.4%) female. The majority of nurses who were working more than 15 years (75%) were suffering from low back pain. Low back pain was more prevalent among female nurses (68%) compared to male nurses (32%). Most participants believed that excessive physical tension and hard work at their worksite were the causes of their chronic low back pain. There were no significant differences between two genders in this regard (P>0.5). In contrast with men, the majority of females (N= 222, 66.8%) believed that psychological tensions at work have been the reasons for their chronic low back pain.
Conclusion: Iranian nurses believed that work – related physical and psychosocial factors could result in low back pain.

Abstract
Aim: Insufficient physical activity in women exposes them to problems such as overweight, diabetes, depression and cardiovascular diseases on top. In between, employees have minimum physical activity due to type of their job. The goal of this study was determining psychological factors effective on the physical activity of women working in University of Tehran based on the theory of planned behavior.
Methods: The research population included female office workers from the University of Tehran, who were selected through a call at this university in 2014 for this descriptive analytical cross-sectional study. For data gathering, a questionnaire was used with acceptable validity and reliability including demographic information and constructs of the Theory of Planned Behavior (TPB) as well as International Physical Activity Questionnaire (IPAQ). Data were analyzed using SPSS21. The statistical bivariate correlation test and stepwise regression test were employed at the significance level of 0.05.
Findings: In this study, behavioral intention had a positive and significant relation with perceived behavioral control (P=0.000) and attitude (P=0.042). Also behavioral intention had a positive and significant relation with physical activity (P=0.000). Stepwise regression analysis was used to evaluate important factors effective on prediction of behavior and intention; it determined 40% of intention variance (R2= 0.408).
Conclusion: The results of the study showed that constructs such as attitude and perceived behavioral control can be effective on the behavioral intention and physical behavior of female employees; therefore, these factors must be seriously considered in educational planning for this group of the society.

Abstract
Aims: Despite the high incidence of wrong ways to wear a backpack in students, the relevant musculoskeletal complications, and the effective role of health education in modification of this behavior, there is no standard questionnaire in this regard in Iran. The aim of this study was to assess the psychometric evaluation of a questionnaire on backpack carrying among female high school students.
Instruments & Methods: The questionnaire on how female high school students carry their backpack in Babolsar, Mazandaran province included 31 items for knowledge (12 items), attitude (10 items), and behavior (9 items) derived from evidenced literature. This questionnaire was evaluated in terms of content and face validity and reliability through internal consistency and stability in 2018. The qualitative and quantitative content validity was evaluated by the panel of experts through Content Validity Index (CVI) and Content Validity Ratio (CVR). Qualitative and quantitative face validity was assessed by the students’ views and measuring impact score, respectively. Internal consistency and stability were measured by Cronbach’s alpha and Intraclass Correlation Coefficient, respectively. Data were analyzed by SPSS 21.
Findings: The results of CVI (0.9-1), CVR (0.8-1), and impact score (2.5-3) were acceptable for the whole scale. Qualitative content and face validity was favorable. Cronbach’s alpha coefficients were appropriate for the whole scale (0.77) and of knowledge (0.68), attitude (0.8), and behavior (0.77). The interclass correlation coefficient for the whole questionnaire (0.68) and the domains of knowledge (0.61), attitude (0.71), and behavior (0.72) indicated that the questionnaire was acceptable.
Conclusion: The study showed the validity and reliability of the health questionnaire on carrying backpack among female high school students. However, more researches should be done to verify this questionnaire for measuring knowledge, attitude, and behavior regarding backpack carrying.

Abstract
The sub-lethal effect of Metarhizium anisopliae and imidacloprid as well as combination of the two control agents was examined on life table parameters of Myzus persicae on different cultivars of canola under laboratory condition at 25 ± 1 ºC, 85% RH and photoperiod of 16L: 8D. The offspring resulting from fungus-infested adults were placed onto leaf discs in Petri dishes separately to record their development time till they reached to adulthood. The number of nymphs produced by each adult aphid was recorded daily. The intrinsic rate of increase(rm) had no significant differences among the three cultivars, and was nearly similar to the net reproductive rate (R0). The concurrent application of M. anisopliae and imidacloprid significantly shortened the aphid longevity on the RGS003 cv compared to the other cultivars. The type of cultivars had no impact on the finite rate of increase (λ) of green peach aphid in any of the treatments. The values of T showed that there was no significant difference among the treatments. Despite having no significant effect on life table characteristics of M. persicae by most of the treatments, the method would be a favorable procedure to control the aphid by raising the fungal concentration. Conducting such research would be worthwhile since there are no antagonistic interactions between the entomopathogenic fungus and the insecticide.

Abstract
In this paper we analyze word Order in four Persian Dialects of Khuzestan, namely Behbahani, Dezfuli, Shushtari and Hendijani, from the typological perspective. The main theoretical framework in this research is Dryer’s word order research (1992). Dabir Moghaddam (1392) has studied 24 features in his research about Iranian languages, which 19 of them are selected from Dryer (1992) and others from Dryer’s Database. In the present research, we also consider the same 24 features. The founded results are compared with the world languages and those of Europe and Asia. The data collection tool and method is a questionnaire based on the features and interviewing the native speakers of these dialects, which were Totally 30. Then, these recordings were transcribed and analyzed on the basis of the mentioned features. The typological behavior of these dialects both in comparison with the world languages and languages of Europe and Asia were studied. Broadly speaking, it was observed that these four dialects have a tendency toward VO languages and in this respect are different from the intermediate type suggested by Dabir Moghaddam (1392) in the case of Persian. It should be noted that these dialects only in 9th and 11th features behave differently and in all other features they share common behavior.

Abstract
In this paper, we analyze the grammatical category of satellite, which was introduced at first by Talmy in his semantic – typological researches. Satellite is a closed – class category that includes any constituent other than a nominal complement that is in a sister relation to the verb root. Talmy categorizes world's languages into two main typological categories: languages, which show framing concepts such as path, aspect, etc. on the verb, are verb – framing languages, and languages, which show framing concepts on the satellites, are satellite – framing languages.
In this study, satellite, its formal representations and the semantic concepts expressed by it, are analyzed. It was found that the main form of satellite in Persian has been the verbal prefixes in the past periods, and now it is the verb - assistant element in Persian compound verbs. It can be said that a kind of lexicalization has taken place in this category. That is, the concepts, which were previously expressed by bound morphemes (prefixes), are now expressed by free morphemes (verb assistant in compound verbs). It was also indicated that Persian language in some cases is compatible with satellite – framing and, in some other cases, with verb – framing languages. So it is suggested that this classification works better if defined as a continuum with satellite – framing languages at one end, and verb – framing languages at the other end, and that languages can be anywhere on this continuum or even be moving toward one of the ends of the continuum.

Abstract
Aims: Back pain is a major public health problem among adolescents and in particular among pupils. This study aimed to evaluate the effectiveness of a back care intervention on spine-related behavior among female students.
Method and Materials: This randomized quasi-experimental study was conducted on female students who were studying in high schools of Babolsar, Iran. Just intervention group received the peer educational program. However, the control group received no intervention. The data were collected by a valid questionnaire regarding backpack carrying . Effective factors in two time points of initial of the study and 6-month follow up were assessed. The data were analyzed by SPSS software version 21 at a significance level of 0.05.
Findings: Totally, 92 students including 46 students in intervention group and 46 students in control group participated in the study. According the findings of the study, mean ± standard deviation of backpack weight before the intervention was (6.14 ± 0.57), ratio of backpack weight to student weight was (0.1 ± 0.01) and backpack carrying duration was (132.6 ± 46.81) which all these variables six months after the intervention reduced to 4.09 ± 0.92; 0.06 ± 0.02 and 93.36 ± 58.06 respectively (P <0.001). The percentage of bilateral backpack carrying in the experimental group increased from 32.6% (n= 15) to 73.9% (n= 34) (P <0.001). However, no significant difference regarding mentioned variables was observed in the control group (P <0.05). The effect size of the intervention was moderate to large (0.4-0.6).
Conclusion: Peer educational interventions could be effective for improving back pack carrying behavior. However, doing more interventional researches in future is recommended.

Abstract
This research is the analysis of the contact zone and the tensions in western women’s travelogues. Travel writing as a genre has always been marginalized within the domain of literary researches, but travelogues by women have been doubly marginalized due to gender. In patriarchal societies, the literature produced by women has never been received as seriously as that by men. Western women, who were colonizers by race and colonized by gender, cannot use the omniscient point of view revealed in men’s travelogues, nor can they assume the objective pose that man travel writers usually boast of. Women, who had an unsure position between the discourses of colonialism and that of femininity, reveal such tensions in their writing that are mostly absent from men’s travelogues. These tensions and the role they play in the self-fashioning of British women can be traced in the images that they offer of the orient in the 19th century.

Abstract
Aims: A backpack is considered as one of the most common cases of carrying things to schools. It is argued that improper carrying can lead to musculoskeletal pain in students. Health education through peers can play an important role in promoting proper backpack carrying behaviors. This study aimed to evaluate peer education on how to carry backpacks in female high school students.
Method and Materials: This quasi-Intervention study was conducted on 92 female high school students in Bahnemir, Iran using multi-stage cluster random sampling. The data regarding knowledge, attitude and backpack carrying behavior were collected through a valied questionnaire before and six months after the intervention. Just intervention group received an educational program in four sessions by peers. The data were analyzed by SPSS
version 21 .
Findings: 92 students with a mean age of 13.90 ± 0.71participated in Intervention and control groups (n= 46 in each group). The variables of knowledge, attitude and backpack carrying behavior improved after intervention (respectively (P <0.001).
Conclusion: According to the results of this study, it is suggested to consider these findings in the design, implementation and evaluation of educational interventions to improve carrying behavior of backpacks among this vulnerable target group.

Abstract
This study aims at analyzing the representation of the tension of Syria in some newspapers and news resources related to the Western world. The theoretical framework in this study is Thompson’s approach (1990) that mentions five general modes of operation of ideology and outlines a number of strategies appropriate to their symbolic expression. In data analysis it was found that the methods used in these texts are legitimation, reification, dissimulation and fragmentation; and the strategies are rationalization, expurgation of the other, euphemism, externalization, passivisation and nominalization. This shows that the newspapers and resources have reported the Syria’s events on the basis of their own opinions and ideologies and purposes; and they have emphasized on the schismatism and difference between people and groups; that is they somehow have distorted the reality and presented it as they themselves perceive it or want to perceive.

Abstract
Aims: Euphrates poplar (Populus euphratica Oliv.) a woody species, which is naturally distributed in desert areas of some parts Asia and Africa. This research was conducted to evaluate the physiological response to salinity stress in 12 in Iran.
Materials and Methods: This study was conducted to evaluate the physiological response to different levels of salinity (75, 150, 225, and 300 NaCl) control and to assess the response physiologic traits such as RWC, EL, MDA, Proline, GB, TSS, plant pigments, SOD, CAT, and GPX.
Findings: The analysis of variance showed that there was a significant difference between treatments all traits. Comparing of that Hamidieh was the highest group and Mahneshan and were in the lowest group. Comparing of treatments showed that 75 was the highest group in terms of performance. The 75 was the highest group in terms of SOD in contrast, 300 and control were in the lowest group.
Conclusion: The result represents that Populus euphratica is a moderate , which could be suggested to reclamation of saline lands with high water table. This uses multiple mechanisms to overcome salinity stress and there is not a clear path to overcome salinity in this species. Cluster analysis divided the examined into five groups based on total traits. The grouping was not based on geographical distance, rather it was based on the conditions of the original habitat especially soil salinity.

Abstract
The genus Agrochola s. l. Hübner, 1821 (Noctuidae, Xyleninae, Xylenini, Xylenina) include more than seventy described species, most of them have a quite typical external habitus. Due to recent revisions on this lineage in the Palaearctic, we decided to update the data of this group in Iran, according to the latest synonymy information and distribution data. A total of 18 taxa belonging to Agrochola s. l. of Iran was listed among them, three taxa namely Agrochola imitata Ronkay, 1984, A. consueta (Herrich-Schäffer, 1852) and A. helvola pallescens (Warren, 1911) are newly recorded for the fauna of Iran. A list of Agrochola s. l. taxa of Iran with their synonymy and distribution data is given together with some notes and illustrations of genitalia and wing pattern for the new records. It is suggested to do more intensive exploration and study the food plants of Iranian Agrochola in their habitats, especially in the Zagros range in western Iran.

Abstract
In this Paper we analyze the pronominal Clitics of Behbahani - a Dialect of Persian – their function and their placement in the sentence. It is shown that pronominal Clitics of Behbahani have four functions, namely subject, direct or indirect object and possessive. Here, we show that subject Clitics have 15 functions in the sentence which is fully discussed in the paper. Direct object Clitics select the following elements as their hosts: the prefix of the imperative verb, the verb prefix in prefixed verbs, the non – verbal part of the compound verb, the prefix showing continuity, the verb and the negating prefix. The hosts of indirect object Clitics are the direct object and the continuity prefix. Possessive Clitics can also choose subject, direct object and the complement as their host. In terms of the grammatical category the host can be a verb, noun, adjective, personal pronoun, Demonstrative, ambiguous pronoun, Clitics, preposition, interrogative pronoun, plural suffix, and RA Ezafe marker in Persian. The dominant position of the Clitics in this dialect is the second position; known as wackernagel position – that is after the first word or the first constituent in the clause. The main point of difference and dissociation between Behbahani and Standard Persian is the subject Clitics; Since there are not such elements as subject Clitics in Standard Persian, but as is seen in the paper, Behbahani has a rich collection of these elements.

Abstract
Graffiti, which is also called silent discourse, reflects different status of women and men in social structure. Hence, studying graffiti can provide us with salient information regarding their anonymous writers’ linguistic and social features. The present study aims at analyzing sociolinguistic features of “theme” and “style” in a corpus of female and male university students’ Persian graffiti in the university campus clarifies some basic sociolinguistic processes such as similarities and differences in communication patterns in female and male (silent) discourse. To this end, a corpus of 640 graffiti (320 written by female university students and 320 written by male ones) were collected from female and male dormitory areas as well as central library study halls at University of Sistan and Baluchestan in a one-month period. These graffiti were then analyzed both qualitatively and quantitatively. The results revealed that both groups had used “love, solicit help from God, depression, declare presence, wish, time and date, swear, poetry, kidding, and friendship” themes. However, “study lesson subjects” were used only in female students’ graffiti while “advice” and “financial anxiety” themes were used only by the male counterparts. Furthermore, content analysis of the graffiti showed that the male students predominantly sought to “confirm power” and “ higher status” while the female ones attempted to “express emotions” and “make solidarity”. In addition, the obtained results with respect to style showed that the male students tended to use more words than their female counterparts, but the latter were more apt to use linguistic elaborated code through prepositions, impersonal pronouns, and dependent clauses and hence had a linguistic superiority over the males.

Abstract
Pertussis toxin (PT), the main virulence factor of Bordetella pertussis is a protein-based AB5-type exotoxin. Methods of pertussis toxin purification are not available exactly because of economic considerations by vaccine companies. The aim of this study was to setup and modify an in-house method for the PT purification based on affinity chromatography to develop acellular pertussis vaccine in future. B. pertussis and CHO cells were provided from Razi Institute (Karaj, Iran). The bacteria were grown in a 300L fermenter (44 h, 35o c, in B2 medium). The fermentation broth was clarified and concentrated by 0.45 µm membrane filter and 10 KDa molecular weight cut-off membrane respectively. Isolation of pertussis toxin was performed based on affinity chromatography by Fetuin Sepharose column. Immune dot blot test showed significant amounts of pertussis toxin qualitatively. The clustering of CHO- cells mono-layer were observed after first hour of applying the purified pertussis toxin and stopped after the twelfth hour. The average amount of extracted PT was 2.53 IU/ml± 0.43. Among the production procedure of whole cell pertussis vaccine, culture broth is discarded, whereas, results showed it was a suitable source for extraction of pertussis toxin. Finally examine other strains and bacterial culture methods to obtain desired pertussis toxin are recommended.
