Due to an increased today’s consciousness of environmental challenges, having green suppliers has become an essential concern for organizations about their supply chains. These considerations can help them to achieve their environmental goals and a competitive position in the industry. Thus, a robust framework to select the suppliers with environmental features and concerns is needed for today’s organizations. This study presents an integrated approach included interpretive structural modeling, Fuzzy MICMAC analysis, Fuzzy AHP and Vikor method. Initially, related factors to the green supplier selection are identified and the using the ISM and MICMAC analysis to determine the interaction of the categories and their subfactors driving and dependence power. The results depict that subfactors of “company resources and administrative capacity” category are the most important and fundamental affecting supplier selection problem. AHP is used to determine each weight of criteria and then using Vikor method and devotions analysis to select the most appropriate supplier. To evaluate the proposed framework a case example of brake pad factory is selected. Results is shown that supplier “C” got the highest rank in overall dimensions of study but in the second rank regard to the environmental dimensions.

Mohammad Hossein Habibi,Bahareh Karimi,Mahmoud Zendehdel,Mehdi Habibi 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.4

Mixed copper-zinc oxide nanostructures (average size 43 nm) were effectively fabricated via coprecipitation route. Field-emission scanning electron microscope (FESEM), powder X-ray diffraction (XRD), fourier-transform infrared spectroscopy (FT-IR) and UV–vis diffuse reflectance spectrum (DRS) were used to characterize the properties of the oxides. At the optimized condition, copper-zinc oxide nanostructures were used for fabrication of working electrodes by doctor blade technique on the fluorine-doped tin oxide (FTO) in dye sensitized solar cells. Their photovoltaic behavior were compared with standard using D35 dye and an electrolyte containing [Co(bpy)3](PF6)2, [Co(pby)3](PF6)3, LiClO4, and 4-tert-butylpyridine (TBP). The ranges of short-circuit current (Jsc) from 0.13 to 0.30 (mA/cm2), open-circuit voltage (Voc) from 0.20 to 0.51 V, and fill factor from 0.34 to 0.29 were obtained for the DSSCs made using the working electrodes. A titania blocking layer on the copper-zinc oxide surface improve both the open-circuit voltage (Voc), short-circuit current (Jsc) and the power-conversion efficiency is consequently enhanced by a factor of approximately five.

Mohammad Hossein Habibi,Bahareh Karimi 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.4

Nanostructured CuO/ZnO composite oxide was prepared by a novel impregnation combustion method using copper nitrate and zinc oxide tetrapod. The X-ray diffraction patterns revealed that CuO/ZnO composite oxide was formed. The effects of different impregnation combustion parameters on the properties of composite were studied by field-emission scanning electron microscope (FESEM), powder X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR) and UV–vis diffuse reflectance spectrum (DRS). The synthesis of ZnO–CuO nanocomposites through impregnation of a zinc oxide tetrapod with copper nitrate aqueous sodium carbonate solutions is reported. During thermal treatment the samples evolve toward the formation of nanocrystalline ZnO particles (zincite phase) dispersed onto tenorite, CuO annealed at 450 ℃. XRD patterns of the precursors calcined at 450 ℃ showed the formation of the zincite–tenorite phases. Field emission scanning electron microscopy (FESEM) exhibited loosely agglomerated hexagonal particles with uniform morphology having a size around 50 nm.

Mohammad Amin Amini,Masoud Karimi,Seyed Saman Talebi,Hossein Piri,Jamshid Karimi 전남대학교 의과학연구소 2022 전남의대학술지 Vol.58 No.3

Infertility is one of the disorders that worries many couples around the world, although novel and molecular methods can be used to cure this disease in different stages. One of the factors that causes infertility in men and women is the increased oxidative stress within the cells, which can lead to damage in zygote formation. ROMO1 is one of the most important proteins in the production of reactive oxygen species. This protein can enhance oxidative stress in the cells and body through cellular pathways, such as TNF-a and NF-kB routes, which will eventually lead to many diseases, especially infertility. We engage several international databases by using keywords; ROMO1, Infertility, and Reactive Oxygen Species, and gained a great quantity of information about ROMO1, Infertility, and Oxidative Stress. Although not proven, it is hypothesized that ROMO1 might elevate oxidative stress by activating NF-kB pathway in the cells, furthermore, TNF-a can arouse ROMO1 that can end up with apoptosis and cell death, which consequently can have a lot of disturbing effects on the body, especially the reproductive system. To sum up, revealing the exact cellular and molecular mechanisms of ROMO1-dependent TNF-a and NF-kB pathways in the pathogenesis of infertility might find interesting therapeutic and management strategies for this disorder.

Mohammad Hossein Habibi,Bahareh Karimi 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.3

Nanostructure CuO/ZnO mixed oxide was systematically prepared via the sol–gel route using zinc andcopper carbonates as precursors (molar ratio of 2:1) under thermal decomposition. The zinc and coppercarbonates precursors have been synthesized by a simple chemical reaction in high yield andcharacterized by its melting point, FT-IR and thermal analysis (TG/DTG). The TG/DTG analysis provedthat the thermal decomposition of zinc and copper carbonates precursors at 255 ℃ and 289 ℃ respectively. Thermo-gravimetric analysis (TG-DTG), X-ray diffraction (XRD), field emission scanningelectron microscopy (FESEM) and diffuse reflectance spectroscopy (DRS) studies were undertaken toinvestigate the thermal properties and electronic structure of the CuO/ZnO mixed oxide catalysts. XRDdata of the samples proved the formation of the nano-crystalline CuO/ZnO mixed oxide. Scanningelectron microscopy (SEM) showed that the spherical-like particles have a diameter in the range 35–45 nm. Optical spectra of the nanostructure show a band peaked at 1.35 eV which is associated to nearband gap transitions of CuO and a band centered at about 3.00 eV related to band gap transitions of ZnOnanostructures.

Cucumber is a commercially important vegetable crop whose growth and productivity are significantly influenced by salinity. Currently, there is little information about salt-related genes and the associated biological pathways involved in salt stress response and tolerance in this crop. Accordingly, this study aimed to unravel the complex molecular mechanism components underlying salinity in cucumber using long non-coding RNA (lncRNA) identification and weighted gene co-expression network analysis (WGCNA). Here, two previously published high-throughput RNA-seq datasets obtained from control and salt-treated tissues of cucumber roots and leaves were employed. First, the potential lncRNAs were identified based on a bioinformatics pipeline. Subsequently, differentially expressed genes (DEGs) and differentially expressed lncRNAs (DE-lncRNAs) were utilized as the input for the WGCNA to identify the clusters of highly interconnected lncRNAs and mRNAs. According to the results, 17 DE-lncRNAs out of 279 and 7 DE-lncRNAs out of 166 putative lncRNAs were detected between salt-treated and control samples in root and leaf tissues, respectively. Using WGCNA, 2226 unique DEGs and 23 DE-lncRNAs were categorized into 10 distinctive co-expression modules, of which, four modules, including blue, brown, yellow, and turquoise, contained the highest number of salt-related genes. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis identified four significantly enriched pathways, including, “plant hormone signal transduction”, “starch and sucrose metabolism”, “MAPK signaling pathway”, and “phenylpropanoid biosynthesis”, related to salt stress response in cucumber. The novel hub genes identified in this study could be exploited for further functional studies aiming to introduce salt-tolerant cucumber varieties utilizing molecular engineering approaches.

The optimal amount of 15 wt%Co/10 wt%K/Al2O3 catalyst was prepared using the impregnation technique in order to study the kinetics of the Fischer-Tropsch synthesis. The rate of synthesis was measured in a fixed-bed micro reactor with H2/CO feed ratio of 1-3 and space velocity in the range of 2,700-5,200 h−1 under reactor pressure of 8 bar and a temperature range of 210-240 oC. The experimental data were best fitted by a Langmuir-Hinshelwood-Hougen-Watson (LHHW) approach rate in the form of −rCO=(k2K1PCOPH2)/(1+K1PCO). Furthermore, the data were fitted fairly well by a power law equation in the form of −rCO=kPCO 1.32PH21.42. The activation energies for LHHW approach model and power law equation were obtained as 138.5 kJ/mol and 87.39 kJ/mol, respectively.

Strategies for sustaining and enhancing nursing students’ engagement in academic and clinical settings: a narrative review

Mohammad Reza Ghasemi,Hossein Karimi Moonaghi,Abbas Heydari 한국의학교육학회 2020 Korean journal of medical education Vol.32 No.2

Students’ engagement in academic-related learning activities is one of the important determinants of students’ success. Identifying the best teaching strategies to sustain and promote nursing students’ engagement in academic and clinical settings has always been a challenge for nurse educators. Hence, it is essential to provide a set of strategies for maintaining and enhancing the academic engagement of nursing students. The purpose of this review was to explore and summarize the strategies that nurse educators use to sustain and promote nursing students’ engagement in academic and clinical settings. A narrative literature review was conducted. CINAHL (nursing content), ProQuest, Medline, the Cochrane, Google Scholar, and Scopus were searched. Of 1,185 retrieved articles, 32 teaching strategies were identified and extracted from the nursing literature. We used thematic analysis approach to organize these strategies into five main categories as follows: technology-based strategies (15 articles), collaborative strategies (10 articles), simulation-based strategies (two articles), research-based strategies (two articles), and miscellanea learning strategies (three articles). As a general comment, these strategies have the potential to promote nursing students’ engagement. Among the strategies discussed in this review, the use of technology, particularly the response system and online learning, was more common among nursing educators, which is in line with today’s advances in smart technologies. The collection presented in this review can be used as a starting point for future research to evaluate the effectiveness of an educational intervention on the academic engagement of nursing students. Nevertheless, due to the lack of experimental studies, the optimal strategies remain to be elucidated through future high-quality experimental study.

Is there an Association between Variants in Candidate Insulin Pathway Genes IGF-I, IGFBP-3, INSR, and IRS2 and Risk of Colorectal Cancer in the Iranian Population?

Karimi, Khatoon,Mahmoudi, Touraj,Karimi, Negar,Dolatmoradi, Hesamodin,Arkani, Maral,Farahani, Hamid,Vahedi, Mohsen,Parsimehr, Elham,Dabiri, Reza,Nobakht, Hossein,Asadi, Asadollah,Zali, Mohammad Reza Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9

Background: Several epidemiological studies have shown associations between colorectal cancer (CRC) risk and type 2 diabetes and obesity. Any effects would be expected to be mediated through the insulin pathway. Therefore it is possible that variants of genes encoding components of the insulin pathway play roles in CRC susceptibility. In this study, we hypothesized that polymorphisms in the genes involving the insulin pathway are associated with risk of CRC. Materials and Methods: The associations of four single nucleotide polymorphisms (SNPs) in IGF-I (rs6214), IGFBP-3 (rs3110697), INSR (rs1052371), and IRS2 (rs2289046) genes with the risk of CRC were evaluated using a case-control design with 167 CRC cases and 277 controls by the PCR-RFLP method. Results: Overall, we observed no significant difference in genotype and allele frequencies between the cases and controls for the IGF-I, IGFBP-3, INSR, IRS2 gene variants and CRC before or after adjusting for confounders (age, BMI, sex, and smoking status). However, we observed that the IRS2 (rs2289046) GG genotype compared with AA+AG genotypes has a protective effect for CRC in normal weight subjects (p=0.035, OR=0.259, 95%CI= 0.074-0.907). Conclusions: These findings do not support plausible associations between polymorphic variations in IGF-I, IGFBP-3, INSR, IRS2 genes and risk of CRC. However, the evidence for a link between the IRS2 (rs2289046) variant and risk of CRC dependent on the BMI of the subjects, requires confirmation in subsequent studies with greater sample size.
