On the Relationship between Export Market Orientation and Export Performance of Tehran Home Appliances Exporting Companies

The rapid increase in the global trade in the last two decades has given prominence to the export performance of companies implying the extent to which they achieve strategic and economic goals for exporting products to foreign markets. The present study explores the relationship between export market orientation and export performance of home appliances exporting companies in Tehran, Iran. A total of 85 companies were selected from the list of 734 exporters of Tehran in 2016. Two standard questionnaires were utilized including export market orientation (Nagy & Beracs, 2012), and export performance of exporting companies (Lin, Huang & Peng, 2014) whose reliability and validity indices were assessed through Cronbach's alpha coefficient and content validity approach, respectively. Also, in order to test the main hypothesis of the research, Smart PLS was used. The results of this study demonstrated a positive and direct relationship between export market orientation and export performance. The findings of the study suggest that exporting companies may boost their export performance through export market orientation with respect to the needs of customers and rivals of the export market and market entry routes

A chemiluminescent method for the detection of H 2 O 2 and glucose based on intrinsic peroxidase-like activity of WS 2 quantum dots

Currently, researchers are looking for nanomaterials with peroxidase-like activity to replace natural peroxidase enzymes. For this purpose, WS 2 quantum dots (WS 2 QDs) were synthesized via a solvothermal method, which improved the mimetic behavior. The resulting WS 2 QDs with a size of 1�1.5 nm had a high fluorescence emission, dependent on the excitation wavelength. WS 2 QDs with uniform morphology showed a high catalytic effect in destroying H 2 O 2 . The peroxidase-like activity of synthesized nanostructures was studied in H 2 O 2 chemical and electrochemical reduction systems. The mimetic effect of WS 2 QDs was also shown in an H 2 O 2 �rhodamine B (RB) chemiluminescence system. For this aim, a stopped-flow chemiluminescence (CL) detection system was applied. Also, in order to confirm the peroxidase-like effect of quantum dots, colorimetry and electrochemical techniques were used. In the enzymatic reaction of glucose, H 2 O 2 is one of the products which can be determined. Under optimum conditions, H 2 O 2 can be detected in the concentration range of 0�1000 nmol·L � 1 , with a detection limit of 2.4 nmol·L � 1 . Using this CL assay, a linear relationship was obtained between the intensity of the CL emission and glucose concentration in the range of 0.01�30 nmol·L � 1 , with a limit of detection (3S) of 4.2 nmol·L � 1 © 2019 by the authors

An analysis of the consequences of the Civilization University

Developing a new Islamic civilization has been mentioned as one of the goals in the Second Phase of the Revolution. For achieving this goal, the academic community becomes more active. Besides having innovation, entrepreneurial, research, and educational functions, leading universities should be able to civilize based on spirituality and religious beliefs and following doctrines of Islam. Data were collected using a semi-structured interview. Inductive content analysis was utilized to analyze the data using the software. Based on the obtained data, extracted components related to the consequences of this approach include: 1) presenting an inspiring pattern, 2) training global leaders, 3) creating a status for the settled region, 4) designing civilized foundations, 5) production prosperity, 6) increasing productivity, and 7) producing entrepreneurial science. Two dimensions including institutionalization of spirituality and knowledge transfer were identified for the main construct. Besides adaption of function to extracted indicators, universities can determine their status in civilization-building

Fabrication of Ti₂SnC-MAX Phase Blended PES Membranes with Improved Hydrophilicity and Antifouling Properties for Oil/Water Separation

In this research work, the Ti2SnC MAX phase (MP) was synthesized via the reactive sintering procedure. The layered and crystalline structure of this MP was verified by SEM, HRTEM, and XRD analyses. This nano-additive was used for improvement of different features of the polyethersulfone (PES) polymeric membranes. The blended membranes containing diverse quantities of the MP (0–1 wt%) were fabricated by a non-solvent-induced phase inversion method. The asymmetric structure of the membranes with small holes in the top layer and coarse finger-like holes and macro-voids in the sublayer was observed by applying SEM analysis. The improvement of the membrane’s hydrophilicity was verified via reducing the contact angle of the membranes from 63.38° to 49.77° (for bare and optimum membranes, respectively). Additionally, in the presence of 0.5 wt% MP, the pure water flux increased from 286 h to 355 L/m2 h. The average roughness of this membrane increased in comparison with the bare membrane, which shows the increase in the filtration-available area. The high separation efficiency of the oil/water emulsion (80%) with an improved flux recovery ratio of 65% was illustrated by the optimum blended membrane
