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.

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.

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.

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.

Analysis of protein-protein interaction network based on transcriptome profiling of ovine granulosa cells identifies candidate genes in cyclic recruitment of ovarian follicles

( Reza Talebi ),( Ahmad Ahmadi ),( Fazlollah Afraz ) 한국축산학회(구 한국동물자원과학회) 2018 한국축산학회지 Vol.60 No.6

After pubertal, cohort of small antral follicles enters to gonadotrophin-sensitive development, called recruited follicles. This study was aimed to identify candidate genes in follicular cyclic recruitment via analysis of protein-protein interaction (PPI) network. Differentially expressed genes (DEGs) in ovine granulosa cells of small antral follicles between follicular and luteal phases were accumulated among gene/protein symbols of the Ensembl annotation. Following directed graphs, PTPN6 and FYN have the highest indegree and outdegree, respectively. Since, these hubs being up-regulated in ovine granulosa cells of small antral follicles during the follicular phase, it represents an accumulation of blood immune cells in follicular phase in comparison with luteal phase. By contrast, the up-regulated hubs in the luteal phase including CDK1, INSRR and TOP2A which stimulated DNA replication and proliferation of granulosa cells, they known as candidate genes of the cyclic recruitment.

Mohammadreza Talebi Ardakani,Anahita Moscowchi,Nasrin Keshavarz Valian,Elham Zakerzadeh 대한구강악안면외과학회 2021 대한구강악안면외과학회지 Vol.47 No.1

Excessive gingival display is an esthetic issue that is commonly managed by different procedures. Lip repositioning is a modality to address concerns of affected patients. The aim of this review was to investigate the scientific evidence on outcomes and long-term stability of lip repositioning surgery with or without myotomy. The electronic search was conducted in three databases: MEDLINE, Embase, and the Cochrane Library up to October 2019. No publication status, language, or time restrictions were applied. The electronic search was complemented by a manual search of the reference lists. Three hundred thirty-eight studies were screened by title, and 16 articles remained for data extraction. The included studies assessed the lip repositioning procedure in 144 patients aged between 15-59 years (134 females and 10 males). Based on the available data, lip repositioning with myotomy/muscle containment can be a successful treatment for minor discrepancies in gingival display in selected cases. However, further well-organized controlled clinical trials are recommended to derive a conclusion about the long-term stability compared with other alternatives.

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.

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.
