The Iranian species in the Chrysis pulchella and C. varidens species groups are investigated. Six species are recognized, two of which are described for the first time: Chrysis gamberoonensis Farhad, Rosa and Talebi sp. nov. and Chrysis brunneamarginata Farhad, Rosa and Talebi sp. nov.. Chrysis gamberoonensis Farhad, Rosa and Talebi sp. nov. belongs to the C. pulchella group and is recognizable within this species group by its unique blue body coloration, scattered mesosoma punctures, polished pit row with elongated pits, and a small median tooth on the lateral edge of metasomal tergum 3. Chrysis brunneamarginata Farhad, Rosa and Talebi sp. nov. belongs to the C. varidens group and is recognizable by the usually colorless apical rim of metasomal tergum 3, and the unique shape of the anterior corners of the scutellum which are enlarged, thickened and directed backward covering the axillary trough. Dichotomous keys and distributional data for Iranian species included in these species groups are provided. Chrysis schwarzi Linsenmaier, 1968 is raised to species rank. The number of Iranian Chrysis species and subspecies is raised to 122.

Talebi, Yahya,Hosseinpour, Mehrab Department of Mathematics 2013 Kyungpook mathematical journal Vol.53 No.1

Let M and X be right R-modules. We introduce several modules relative to the class of B(M, X) and we investigate relation among these modules. In this note, we show if M is X-${\oplus}$-supplemented such that $M=M_1{\oplus}M_2$ implies $M_1$ and $M_2$ are relatively B-projective, then M is an X-H-supplemented module.

Genetic Diversity and Population Structure of Four Iranian Alfalfa Populations Revealed by Sequence-Related Amplified Polymorphism (SRAP) Markers

Talebi, Majid,Hajiahmadi, Zahra,Rahimmalek, Mehdi 한국작물학회 2011 Journal of crop science and biotechnology Vol.14 No.3

In the present study, genetic diversity of 48 individual plants from four Iranian cultivated populations of alfalfa (Medicago sativa L.) was evaluated using sequence-related amplified polymorphism (SRAP) markers. Fourteen SRAP primer combinations produced 193 fragments of which 95 were polymorphic. The number of polymorphic fragments detected per primer combination ranged from 3 to 10 bands with an average of 6.78 bands. Average polymorphic information content (PIC) was 0.343 for all primer combinations. Although the AMOVA (analysis of molecular variance) results showed a significant difference in the genetic diversity among the populations (P < 0.0001), the genetic variation mainly caused by the variation of intra population accounted for 93.17% of the total genetic variation. Unweighted pair-group method arithmetic average (UPGMA) analysis of the marker data clearly separated the populations of subtropical (Yazdi) and semi-cold (Hamadani and Nikshahri) as well as Kodi, an improved population. It can be concluded that SRAP markers are useful for studying diversity and relationships among and within alfalfa populations.

TALEBI, A.A.,RASHMANLOU, HOSSEIN,AMERI, REZA The Korean Society for Computational and Applied M 2016 Journal of applied mathematics & informatics Vol.34 No.3

In this paper, we introduce product interval-valued fuzzy graphs and prove several results which are analogous to interval-valued fuzzy graphs. We conclude by giving properties for a product interval-valued fuzzy graph.

NEW CONCEPTS OF REGULAR INTERVAL-VALUED FUZZY GRAPHS

TALEBI, A.A.,RASHMANLOU, HOSSEIN,DAVVAZ, BIJAN The Korean Society for Computational and Applied M 2017 Journal of applied mathematics & informatics Vol.35 No.1

Recently, interval-valued fuzzy graph is a growing research topic as it is the generalization of fuzzy graphs. The interval-valued fuzzy graphs are more flexible and compatible than fuzzy graphs due to the fact that they allowed the degree of membership of a vertex to an edge to be represented by interval values in [0.1] rather than the crisp values between 0 and 1. In this paper, we introduce the concepts of regular and totally regular interval-valued fuzzy graphs and discusses some properties of the ${\mu}$-complement of interval-valued fuzzy graph. Self ${\mu}$-complementary interval-valued fuzzy graphs and self-weak ${\mu}$-complementary interval-valued fuzzy graphs are defined and a necessary condition for an interval valued fuzzy graph to be self ${\mu}$-complementary is discussed. We define busy vertices and free vertices in interval valued fuzzy graph and study their image under an isomorphism.

Entropy and exergy analysis and optimization of the VVER nuclear power plant with a capacity of 1000 MW using the firefly optimization algorithm

Talebi, Saeed,Norouzi, Nima Korean Nuclear Society 2020 Nuclear Engineering and Technology Vol.52 No.12

A light water nuclear Reactor has been exergy analyzed, and the rate of irreversible exergy loss and exergy destruction is calculated for each of its components. The ratio of these losses compared to the total input exergy loss is calculated, which shows that most irreversible losses occur in the reactors, turbines, steam generators, respectively, as well as in the downstream operations. The main aim of this paper is to optimize the power plant using an innovative firefly algorithm and then to propose a novel strategy to improve the overall performance of the plant. As shown in the results, the exergy destruction rate of the plant decreased by 1.18% using the firefly method, and the exergy efficiency of the plant reached 29.3% comparing to the operational amount of 28.99%. Also, the results of the firefly optimization process compared to the Genetic algorithm and gravitational search algorithm to study the accuracy of the model for exergy analysis fitness problems in the power plants and the results of this comparison has shown that the results are nearly similar in the mentioned methods. However, the firefly is faster and more accurate in limited iterations.

Saeedeh Talebi,Andrew S. Day,Majid Khadem Rezaiyan,Golnaz Ranjbar,Mitra Zarei,Mahammad Safarian,Hamid Reza Kianifar 대한소아소화기영양학회 2022 Pediatric gastroenterology, hepatology & nutrition Vol.25 No.1

Inflammation plays an important role in the outcome of patients with cystic fibrosis (CF). It may develop due to cystic fibrosis transmembrane conductance regulator protein dysfunction, pancreatic insufficiency, or prolonged pulmonary infection. Fecal calprotectin (FC) has been used as a noninvasive method to detect inflammation. Therefore, the aim of the current meta-analysis was to investigate the relationship between FC and phenotype severity in patients with CF. In this study, searches were conducted in PubMed, Science Direct, Scopus, and Embase databases up to August 2021 using terms such as “cystic fibrosis,” “intestine,” “calprotectin,” and “inflammation.” Only articles published in English and human studies were selected. The primary outcome was the level of FC in patients with CF. The secondary outcome was the relationship between FC and clinical severity. Statistical analysis was performed using Comprehensive Meta-Analysis software. Of the initial 303 references, only six articles met the inclusion criteria. The mean (95% confidence interval [CI]) level of FC was 256.5 mg/dL (114.1-398.9). FC levels were significantly associated with pancreatic insufficiency (mean, 243.02; 95% CI, 74.3 to 411.6; p=0.005; I2=0), pulmonary function (r=–0.39; 95% CI, –0.58 to –0.15; p=0.002; I2=60%), body mass index (r=–0.514; 95% CI, 0.26 to 0.69; p<0.001; I2=0%), and Pseudomonas colonization (mean, 174.77; 95% CI, 12.5 to 337.02; p=0.035; I2=71%). While FC is a reliable noninvasive marker for detecting gastrointestinal inflammation, it is also correlated with the severity of the disease in patients with CF.

Manije Talebi,Baris Majnounian,Ehsan Abdi,Fateme Berenji Tehrani 한국산림과학회 2015 Forest Science And Technology Vol.11 No.1

Forest roads are an essential infrastructure and prerequisite in the management of forested areas. Sustainable managementof roads depends on regular and timely forest road maintenance. A road inventory is the first step of forest roadmanagement, control of construction standards, and maintenance operation; and GIS can be a powerful tool foracquirement, analysis, and management of data in road management. The purpose of this study was to obtain the requiredinformation to assess existing road standards by way of a road inventory and use the results to schedule maintenanceoperations. To achieve this goal, a part of the road network from Kaleibarchay watershed in Arasbaran forest wasinventoried, and cross sectional components were measured and compared to standard ones. Culverts along the road werealso investigated. Road components, problems of surfacing, and slope stability were analyzed in ArcGIS9.3 software. Theresults showed significant differences between existing parameters and standard ones, and the exceptions were side ditchdepth and roadbed. The results of culvert assessment showed that the road segment only had one culvert. According to theresults, cross-slope has the highest consistency with standard values. Around a quarter (25.19%) of the road length had nosigns of surfacing problems. Among surfacing problems, rutting had the highest abundance and cut slope had morestability problems than fill slope. In order to have better management of drainage systems, we suggested some places forinstalling new cross drains including culverts and fords. The results of this research can be used in developing effectivemaintenance operations for the road in this study, and also as a model to study and collect required inventory data and inapplying GIS to forest roads management.

Goodarz Talebi,Sayed Javid Royaee,R.L. Keiski,M. Huuhtanen,Hamid Imamverdizadeh,Morteza Sohrabi 한국공업화학회 2008 Journal of Industrial and Engineering Chemistry Vol.14 No.5

In this study, two types of Beta zeolites having different Si/Al ratios (11.7 and 24.5) were synthesized hydrothermally using tetraethyl ammonium hydroxide (TEAOH) as a template. Different amounts of platinum (0.2%, 0.5% and 1.2%) were loaded on the protonated form of zeolite by incipient wet impregnation method applying hexachloroplatinic acid in 0.2N Cl progressive ion solutions. Catalytic hydroisomerization reactions were carried out at atmospheric pressure in a fixed bed reactor with vertical placing and downward flow at three different temperatures, various WHSV (weight hourly space velocity) and n-H2/n-HC (molar hydrogen/hydrocarbon) ratio. Increase in Si/Al ratio in zeolites structures from 11.7 to 24.5 promoted selectivity and yield. It was found that optimum platinum content depends on the Si/Al ratio (zeolite acidity) in catalysts. Monobranched to dibranched isomers ratio were correlated with a linear function of n-heptane conversion. Such a correlation was found to be valid for various Si/Al ratios, metal content, processing temperature and pressure, WHSV and hydrogen to hydrocarbon ratio. This observation may indicate that in isomerization reactions, the monobranched isomers are first produced but subsequently transformed into multibranched isomers.

ObjectiveTo determine the effect of a social network-based cognitive-behavioral intervention on postpartum body image andsexual life of primiparous women. MethodsIn this single-blind randomized controlled trial, 82 postpartum women were allocated into two intervention andcontrol groups (allocation ratio, 1:1) using permuted block randomization. Primary outcome was change in bodyimage scores between the groups over time. Secondary outcomes were genital self-image, sexual quality of life, andsexual satisfaction. The intervention group participated in eight (2 weeks) 60-minute sessions through WhatsApp(WhatsApp Inc., Mountain View, CA, USA). Data were collected at recruitment, post-intervention, and 1-month offollow-up. ResultsCognitive-behavioral intervention had a medium effect on improving body image in postpartum women (partial etasquared, 0.33; P<0.001). The results showed significant differences between the two groups regarding sexual qualityof life and sexual satisfaction at 1-month follow-up. ConclusionThe results of this study can be used to develop psychological interventions targeting body image in postpartumwomen.
