Abstract
Increasing need for drought adaptation measures to conserve water and sustain crop yield in water-scarce regions, driven by severe and recurrent droughts. Achieving sustainable production entails studying deficit irrigation as a means to enhance water productivity and selecting genotypes resilient to soil water deficits. In the present study, 17 different melon (Cucumis melo L.) genotypes collected from the Van Lake Basin and 3 hybrids and 1 standard melon cultivar for control purposes were used. The study was carried out under climate room conditions. Two different irrigation levels (I100: 100% full irrigation, I50: 50% deficit irrigation-DI) were applied in the study for deficit irrigation. The applications started with the emergence of the second true leaves of the plants and after one-month, different growth, nutrient, and enzyme contents of the seedlings were determined. In general, it was determined that deficit water application negatively affects seedling growth, and and root dry matter, stomatal width and density, potassium, APX and SOD enzymes, and MDA content increased, while the other examined parameters decreased. The genotypes of the Van Lake Basin melon were found to vary as a result of the findings.

Abstract
Aims: The postpartum period presents significant physical, emotional, and social challenges for mothers. One common issue is postpartum blues, which can negatively impact maternal well-being. This study aims to analyze the effect of yoga exercises on preventing postpartum blues in postpartum mothers using family health media as an intervention.
Instrument & Methods: A quantitative analytical study with a quasi-experimental approach was conducted. The study involved postpartum mothers at the Alisah Clinic, utilizing a total population sampling technique. Data were collected through structured questionnaires and interviews, then analyzed statistically using SEM-PLS to evaluate the relationship between yoga practice frequency, duration, family support, and postpartum blues prevention.
Findings: The results show that yoga exercise significantly reduces postpartum blues symptoms. Higher frequency and longer duration of yoga sessions contribute to better mental and physical well-being. Additionally, the quality of family health media plays a crucial role in enhancing knowledge and promoting behavioral changes supportive of yoga practice. Family support was found to positively influence the consistency of yoga practice.
Conclusion: Yoga exercises, when practiced regularly with adequate duration and supported by quality health media and family involvement, are effective in preventing postpartum blues. These findings highlight the importance of accessible and structured yoga programs as part of postpartum mental health care.

Abstract
Background: Leptospirosis has been recognized as an important reemerging infectious disease caused by pathogenic Leptospira spp. A major challenge of this disease is the application of a basic research to improve diagnostic method. Outer membrane proteins of Leptospira are potential candidates that could be useful in diagnosis. Among them the lipL41 is an immunogenic protein which is present only in pathogenic serovars. In order to evaluate genetic conservation of the lipL41 gene, we cloned and sequenced this gene from Leptospira interrogans serovar Canicola.
Materials and Methods: Following the DNA extraction from the serovar, the lipL41 gene was amplified and cloned into pTZ57R/T vector and transformed into the competent E. coli (Top10). Recombinant clones were confirmed by colony PCR and DNA sequencing. The related sequences were then analyzed and compared with the sequences in the Genbank database.
Results: PCR amplification of the lipL41 gene resulted in a 1065 bp PCR product. The PCR based on the lipL41 gene detected all the pathogenic reference serovars of the tested Leptospira spp. It was revealed that in Iran the homology of the lipL41 gene between vaccinal and clinical serovars of Canicola was 100%. It also showed >95.9% homology with other pathogenic serovars in Genbank database, which indicates genetic conservation of this gene.
Conclusion: Because of the conservation of lipL41 gene among different strains of Leptospira and its exclusive presence in leptospira, it was revealed that the cloned gene could be further used as a good candidate for developing diagnostic methods such as ELISA and as positive control in diagnostic PCR.

Abstract
By Looking at Iranian Contemporary Architecture and it's different generations It can be found that there are examples of excellence in architecture which Can be based on the characteristics and components of the Architectural Review, They to a specific stream architecture in Iran and Independent of the architectural approaches of the West, as an affiliate. This research is based on case studies, it followed up with an analysis of the signs and current thoughts available in the text architecture, to identify trends and approaches in contemporary architecture generations and answer to the question whether there is significant sequence in the concepts used by architects at different periods? It is assumed that the defining trends of Iranian contemporary Iranian architects from Iranian modernism to nationalist tendencies, Revitalization or classical market, while It can also work in conjunction with the value and importance of the historical context of the assessment, Explaining the origins and reliable indicators, Makes the flow of existing theoretical on Iranian history of contemporary architecture be recognized. Defining the correct position of Iranian Islamic architecture in the post modern world elicits various points of view. The increasing importance of literature related to linguistic philosophy, post-constructivism, cultural relativism, and the end of ideology has instigated a sort of mental inflammation in the community of Iranian architects. A pragmatism abstracted from the environment is one of the trends that have developed in this respect. Based on results of a comparative analysis of three generations of Iranian contemporary architects work, Also, according to the authors describe, It follows that the theory of contemporary architecture in Iran, Within four specific categories, such as The giver ideas, Aesthetic style references, Selection Form and types of materials can be explained. The analysis of these four components in architecture works explains that the giver ideas of posit has been followed with more persistent in the pursuit of different generations and over time in comparison to the other components has less changes. This perception can underline the existence of a common discourse between color, smell and Iranian structure that can be the missing detail of the Iranian contemporary architecture. Throw a glance at current Iranian architecture and its generation, it is realized that there are some preferable samples in this period which could be referred as a special stream in Iranian architecture and in depended from west approaches, based on the type of characteristics and architectural criticize components. Iranian current architecture is one of areas that has not been studied exactly and by analyzing works and current stream and it is especially referable. It is realized from rapid and also extreme changing of Iranian architecture that the trend to classical architecture has been changed in different situation. These rapid changes have been happened due to modernizing and mechanism that could be considered as modern period effects. Iranian challenges with contemporarily, in recent two centuries, was expanded in governmental and intellectual parties. In this era, extreme changes was happened in the most areas including architecture and provide different approaches and simultaneously some intent to classical thinking. This research, based on case study approach, followed analyzing the signs and streams of consciousness in architectures work contexts, to realize the approaches of current generation of architecture and also find the answer for a question about finding a reputable track record in the used concepts with architects depending their different periods. It is assumed that, specifying the definition of Iranian current architect’s trend, like Iranian modernism, nationalism, renovate or classical popular approaches, helps to recognize theoretical stream of current Iranian architecture with realizing and specifying roots and valuable indicators, and furthermore can assess the importance and worthiness of each work. Reviewing current Iranian architecture shows, in spite of various generations, the main concepts have not any diversity and its evaluation will be realized and performed with improvement of these concepts. Anyway, because of this subject that the attention to current Iranian architecture for finding a reliable classification, needs reviewing basic concepts like methodologies, forms and architectural studies, as the basis of the effective items like design ideas, design locations and frame works, design themes, spatial concepts, visual shapes and the used material, therefore we have to realize the hide vision of these three generations of architecture, considering right viewpoint, to provide a statement for classifying or finding a similar theme between Iranian and current world architecture. Based on the results of comparative analysis of three generation of Iranian architectural works, and also regarding the clear-sighted authors description, it seems that, the stream of theory in Iranian current architecture could be realized as a framework by four specific categories including structural giver ideas, stylistics refers, form selecting and type of materials. Analyzing these four categories in architectural works shows that the structural giver ideas have been followed by different generation with more persistent and have the minor changes than other categories during this era. This perception discovers a common thought in Iranian current architecture that can be the missed stream of it. The trends and ideas underlying a design are the main concepts on which the main design of a work of architecture is based on. Conceptually, the structural idea of a design is the main definition that architecture is based upon and in some literature, it is even viewed as a concept. Based on evaluation and analysis of the frameworks of the prominent works of Iranian architecture of three generations, mainly after the Islamic Revolution, structural ideas of architectural designs and the product of prominent Iranian works of architecture is a mélange of international and regional intellectual currents, the leading culture of the designs as they relate to their era and social, political,cultural and economical interactions. Furthermore, a deep review of contemporary architecture in Iran after Islamic reveloution, points out a lack of familiarity with main universal contemporary architectural theory, which is the main reason behind the architects, designers, professors and researchers of architecture, and most importantly, those who enjoy architecture.

Abstract
Rigidoporus microporus is a major threat to Hevea brasiliensis in the rubber growing regions of the world. In vitro synthetic fungicidesensitivity assays of Tridemorph, Benomyl and Bayfidan at seven different concentrations, and in vivo effectiveness of the three fungicides on R. microporus inoculated on rubber seedlings were evaluated. The three chemical fungicides used in this study were effective on R. microporus, with Tridemorph being the most effective. The minimum inhibitory concentration value for Bayfidan was between fungicide concentrations of 0.001µg/ml and 0.005µg/ml. Percentage of plant death and presence of rhizomorph recorded at two months after inoculation were higher than that recorded at the termination of five months experimental period after inoculation. Tridemorphtreatment had the highest plant health both at two months and at five months after inoculation. Decline in plant death from the third months onward suggested a reduction in fungal activity of R. microporus. Tridemorph was most effective among the three fungicides tested as it exhibited higher mycelial percentage inhibition in the management of R. microporus in vitro and higher plant health of rubber seedlings in vivo.

Abstract
Taxis, or mora’atal-nazir, did not occupy a considerable position in rhetorical books until the fifth century after hijra. Radouyani introduced it for the first time, and then, another rhetorician elaborated on this figure and, gradually, the termbecame established in rhetoric. There are traces of this term in earlier descriptions of other tropes such as i’etelaf, taqsim, and moghabeleh. This article, drawing on Islamic rhetoric, gives a more nuanced definition of this term. Reviewing the history of mora’atal-nazirshows that this trope shapes a chain of semantic relation between different parts of speech. A similar relation, under the category of ‘alagheh,can be found in different forms of figurative language. I have also studied different functions of this trope and how we can evaluate it.

Abstract
The quest for new sources of cheap and eco-friendly insecticide for insect pest management remains a major challenge facing cowpea farmers in many developing countries. In this study, the toxicity and biochemical mechanisms associated with the insecticidal efficacy of acetone and n-hexane extracts of Xylopia aethiopica (Dunal) and Senna occidentalis (L.) on Callosobruchus chinensis (L.) were investigated. The insecticidal efficacy varied with concentration, exposure time and extracts type. Acetone extract of X. aethiopica was less toxic (LD50 = 2.47%) than its n-hexane extract (LD50 = 1.39%) but with S. occidentalis, acetone extract was more toxic (LD50 = 0.73%) than n-hexane extract (LD50 = 1.37%). Acetone extract of both plants evoked a significant reduction in egg-laying and eclosion ability of adult C. chinensis compared to n-hexane extract except on cowpea pre-treated with acetone extract of S. occidentalis. Only the extracts of X. aethiopica reduced protein concentration compared to control. The activity of glutathione reductase and glutathione peroxidase was significantly reduced by both extracts of S. occidentalis while only n-hexane extract of S. occidentalis elicited a significant reduction in the activity of glutathione S-transferase and trehalase compared to other treatment levels. GC-MS analysis depicted Diisoocotyl phthalate (50.37%) and isomers of Aromandendrene (19.22%) as the main compounds in S. occidentalis and X. aethiopica respectively. Both botanical extracts also contained other insecticidal and insectifuge compounds in differential amounts. Overall, the findings demonstrated the potential of both botanical extracts, particularly acetone extract of S. occidentalis as alternatives to synthetic insecticide for controlling adult C. chinensis.

Abstract
Backgrounds: The burden of bacteremia in febrile cases is still poorly understood in Nigeria as in many sub-Saharan African countries due to diagnostic limitations. This study aimed to determine the prevalence of Salmonella bloodstream infections and antimicrobial resistance patterns of bacterial isolates recovered from febrile patients in Lagos, Nigeria.
Materials & Methods: A total of 300 blood samples were collected from febrile patients attending four medical centers in Lagos during August 2020 to July 2021. Clinical isolates were identified using API 20E kit. qPCR was used to detect Salmonella isolates in positive blood culture samples using a specific primer set. All isolates were subjected to antimicrobial susceptibility tests using standard procedures.
Findings: Totally, 55 bacterial isolates belonging to six bacterial genera were identified, including Salmonella (n=4, 7.27%), Klebsiella species (n=23, 41.82%), Escherichia coli (n=6, 10.91%), Proteus species (n=13, 23.64%), Serratia species (n=7, 12.73%), and Citrobacter species (n=2, 3.64%). In this study, the detection rate of Salmonella isolates in positive blood culture samples using qPCR and invA gene primer set was 100%. Salmonella isolates were 100% resistant to ceftazidime, cefotaxime, and doripenem. Multidrug resistance (MDR) was observed in Salmonella and other bacterial isolates.
Conclusion: In this study, qPCR using the invA primer set was found to be highly specific for Salmonella detection. All the bloodstream bacterial pathogens in this study were MDR; thus, there is a need for continuous evaluation of antibiotics in medical settings. Further molecular studies on these bacterial isolates is essential.

Abstract
Aims: The bio-toxicity of silver nanoparticles (AgNPs) in the aquatic ecosystem and the detection of lethal concentrations of this material are of importance. The aim of this study was in vivo comparative toxicity of silver nanoparticles and bio-productivity in zebrafish (Danio rerio) in embryo and adult stages.
Materials and Methods: The present experimental study was carried out on 30 fertilized eggs and 30 adult zebrafish and the effects of chemical and bio-productivity of AgNPs were evaluated by brown seaweed (Sargassum boveanum) in evolutionary stages of the embryo and adult zebrafish with a control group and in incremental concentrations. The mortality rate was recorded at 24, 48, 72, and 96 hours after exposure and the data were analyzed by EPA Probit Analysis 1.5 and SPSS 19 softwares, using one-way analysis of variance and Duncan's multiple range test.
Findings: The toxicity of both types of AgNPs in both evolutionary stages was increased with increasing concentrations and time (p<0.05). After 96 hours, the lethal concentration 50 (LC50) in adult fish was 0.788mg/l for chemical AgNPs and 0.409mg/l for bio-produced AgNPs. Mortality rate at the highest concentration (3mg/l) of AgNPs at 72 and 96 hours in all groups was 100%.
Conclusion: Comparison of the toxicity result showed that the biosynthesis form of AgNPs is more toxic potential than chemical form of AgNPs. It seems the sensitivity of embryo stage to both of silver nanoparticles more than to mature stage.

Abstract
Aims: The conscious regulation of learning enables students to cope with academic, social and technological demands in times of COVID-19 pandemic in a positive or negative way. The aim was to explain the influence of cognitive learning strategy on academic stress in university students.
Instrument & Methods: This quantitative research with basic type a hypothetico-deductive method was performed. The sample of two hundred students (one student calculated through probability sampling) who were administered instruments with content and construct validity, as well as reliability by Cronbach's Alpha of 0.99 for learning strategies and academic stress.
Findings: The predominant cognitive strategy was information coding, considered risky because it produces high levels of stress, as well as idiosyncratic underlining, reviewing aloud and repeated review; while applications, metaphors, groupings and concept maps were considered protective, because they do not generate academic stress. Likewise, social interactions had a significant influence on the information processing support strategy.
Conclusion: The information coding, epigraphy, applications, searching for encodings, and social interactions strategies have the highest effect on cognitive learning, information acquisition indicators, information coding, information retrieval, and processing support, respectively.

Abstract
Aims: This study was performed to determine the relationship between academic procrastination and anxiety in students of a university in the department of Apurimac, Peru.
Instrument & Methods: In this non-experimental, basic, descriptive-correlational study, the sample consisted of 196 university students from the first four cycles of Initial Education in 2020. Data collection was through surveys for which two questionnaires were used: the Academic Procrastination Scale (EPA) and the State-Trait Anxiety Questionnaire (STAI). Both instruments were found to be highly reliable (Cronbach's alpha greater than 0.8 in both cases). The descriptive and inferential analyses were carried out with SPSS 25 software. Spearman's Rho was applied to corroborate the value of the relationships.
Findings: Most of the students exhibited high levels of academic procrastination and anxiety. Inferential analysis showed a statistically significant (p<0.05) but direct and weak relationship (r=0.171) between academic procrastination and anxiety. State and trait anxiety were also evaluated and it was found that their relationship with academic procrastination was positive and weak (Pearson's r close to 0.25 in both cases).
Conclusion: The constant practice of procrastinating behavior is a product of recurrent thoughts of postponing academic activities, which is part of the formation of the personality that the temperament and character of the individual.

Abstract
Enzymes play an essential role in catalyzing the reactions for multiple industrial applications. One of these critical industries with a worldwide application is paper and pulp, which is cost-effective in increasing attention. Xylanases are potential enzymes that proved their abilities in a broad range of applications, specifically in the paper and pulp industry as a biobleaching agent and dye removal biocatalyst. In these decades, the production of novel enzymes from natural sources is conceivable, especially with applying the culture-independent method of metagenome. This practical approach provides the opportunity to identify the novel enzymes from uncultivable microbial diversities. Concerning the importance of the thermostable enzymes for industrial applications and their better action in harsh conditions, this study aimed to identify novel thermostable xylanase from metagenomic data of sheep rumen by applying the in-silico screening. The thermostable xylanase was extracted from the ruminal DNA and after cloning and expression named PersiXyn5. The enzymeschr('39') kinetic parameters, including Km, Vmax, and its specific activity, were examined. The enzyme was optimally active at 80

and pH 8 and could retain 58% of its maximum activity after 2h of incubation at 90

. The thermostable, alkali PersiXyn5 was an efficient enzyme in the paper industry and poultry feed and fuel applications.

Abstract
Empirical studies examining the effects of language learning have largely focused on linguistic changes in learners. Regrettably, this has left the non-linguistic changes under-researched. To address this, the current study examined what self-identity changes Chinese university EFL learners experienced and how individual characteristics (i.e., gender, starting age of study, and university major) may have affected these changes. To do so, a self-identity change questionnaire was administered online to 416 Chinese university students using a convenience sampling strategy. Seven identity change variables were measured by the survey: changes in (1) positive self-confidence, (2) negative self-confidence, (3) productive identity change, (4) additive identity change, (5) zero change, (6) subtractive change, and (7) split change. Confirmatory factor analysis confirmed that the items on the questionnaire measured their intended identity change variable. Descriptive statistics showed that participants experienced changes in self-confidence, additive identity, and productive identity, but did not experience subtractive or split change. The results also showed that the participants were unaware that they had experienced any changes. Multiple analysis of variance results showed that the individual characteristics contributed to some variation in the identity changes. The findings support theories suggesting that language learning contributes to non-linguistic changes within learners.

Abstract
Aims: Today, the energy crisis has become a global problem, and all countries are involved in this crisis, so solutions with small results can lead to significant changes on a macro scale. Passive cooling strategies are a method to reduce energy consumption in buildings and help improve and promote energy management in hot climates.
Methods: The current study analysis ventilation performance related to constructing four-story buildings. Furthermore, there is a heavy investigation into the mechanical aspects of ventilation; hence this research is going to fill the gap in the architectural view of the ventilation system. The modeling uses energy software (Design-Builder).
Findings: Studies have been conducted to investigate the position of the stack, and the earth's rotation, in addition to changes in the materials of the stack in the residential area of Dezful city. The most frequent residential land size in the residential area of Dezful is 10x20 square meters. In addition, changing materials has a direct impact on stack ventilation.
Conclusion: The simulation outcomes demonstrated that material and site rotation changes could alter the stack's performance, meaning that glass can be more effective than aluminum. Still, the position of the stack in the plan does not make a significant difference in the stack's performance. The result is outstanding for architects and all people working in this field, which can be a guideline in designing energy-efficient.
