During the last decades, environmental crises through energy consumption and economic growth were noticed as a growing concern among researchers. The industrial sector is the main part of economic growth in each country using conservative energy and emitting carbon dioxide that causes global warming. The Paris agreement and Kyoto protocol were two agreements to prevent governments from emitting CO2 freely. Purpose of this research was to investigate the cement industry, steel industry, and automobile industry products’ effects on CO2 emissions in Iran and to rank them according to their measured effects on CO2 emissions. The methodology used in this study was to estimate equations with CO2 emissions as a dependent variable and cement, steel, and automobile industries’ products with ordinary least squares (OLS) and generalized moment method (GMM) approaches. Stationary, Johansen cointegration, Durbin-Watson, Breusch-Godfrey, Chow breakpoint, and normal residual tests were checked. In-sample forecasting was implemented to check the precision of the estimation and an updated ranking was reported as a final result to consider which industry has affected CO2 emissions more than the others per unit of production cost. In conclusion, the cement industry, steel industry, and automobile industry had the most positive effects on CO2 emissions, respectively. This result is suitable to prioritize the industries for enhancing green technology and optimizing industrial production for a more sustainable economy.

In recent years, there have been significant changes on governmental agencies than any other organizations. There is also an agreement that any improvement on economy requires an efficient government. Governments must be responsive against their people and society but there are evidences that many governmental agencies are not able to meet people’s needs despite access to financial resources because of lack of entrepreneurial approach. This paper presents an empirical investigation to study the role of entrepreneurship governmental groups on macro-economic strategies. The study uses structural equation modeling, by designing a questionnaire in Likert scale, and distributes it among 384 randomly selected university professors in city of Tehran, Iran. The results confirm that technology-based economy, creative human resources and training, competition in the economic environment, knowledge creation, dissemination and application and promoting a culture of innovation and entrepreneurship influence positively on entrepreneurship governmental groups. In addition, the positive effects of entrepreneurship governmental groups on national commitment and management are confirmed.

In this work, acidity constants protonated form of 4.4 & apos; -bis astilbene-2,2 & apos; -disulfonic-disodium salts (TRIAZ) have been determined spectrophotometrically and spectrofluorimetrically at 25?C and ionic strength of 0.1M KNO3. A program based on MCR-ALS applied for determination of acidity constants. The results show that the peak values of dye are influenced by the presence of anionic, cationic, and nonionic surfactants. The effects of sodium dodecyl sulfate (SDS), Triton X-100 (TX-100) and cetyl trimethyl ammonium bromide (CTAB) as a surface-active agent on the acidic and basic forms, and the spectral properties of dye were studied. Also, we determined the critical micelle concentration (CMC) for these surfactants by spectrophotometric and spectrofluorimetric triazine dye probes. In addition, by using of evolving factor analysis (EFA) and multivariate curve resolution alternative least squares (MCR-ALS) methods, acidity constants were acquired.

This paper derives a semi-analytical solution to determine displacements and stresses in a thick cylindrical shell with variable thickness under uniform pressure based on disk form multilayers. The proposed study partitions the thick cylinder into disk-layer parts based on their thickness of the cylinder. According to the existence of shear stress in the thick cylindrical shell with variable thickness, the equations governing disk layers are acquired based on first shear deformation theory (FSDT), which are in the form of a set of general differential equations. In this study, the cylinder is partitioned into n different disks and n sets of differential equations are derived. The solution of these equations provides displacements and stresses based on the boundary conditions and continuity conditions between the layers. The results are compared with those obtained through the analytical solution and the numerical solution. For the purpose of the analytical solution, matched asymptotic method (MAM) and for the analytical solution, the finite element method (FEM are implemented.

Consumer perception plays essential role for market development. Consumer perception can be defined as a marketing concept, which includes a customer & apos; s impression, awareness and/or consciousness about a firm or its offerings. This paper investigates the effect of customer relationship management factors on consumer perception in Iranian banking industry. The study designs a questionnaire in Likert scale and distributes it among 300 randomly selected managers who worked for Bank Saderat Iran. Cronbach alpha has been calculated as 0.788, which is well above the minimum acceptable level. Using principal component analysis, the study has determined that six factors influences the most on consumer perception; namely: Customer oriented, Organizational strategy, Organizational resources, Organizational structure and Organizational culture.

A value chain is a chain of necessary activities that a company operating in a specific industry executes in order to deliver a valuable product or service for the market. Value chain plays essential role for development of a successful business unit. This paper presents an empirical investigation to study the effects of value chain on capabilities of knowledge production, implementation and distribution. The impact is also studied for effective knowledge implementation for economic development. Using historical economic data of World Bank database gathered from member countries of the Organization of Islamic Cooperation, the study has detected positive and meaningful effects of Value Chain Presence on Knowledge Economy Index and Knowledge Index.

In this work, a variety of highly substituted quinolines were readily synthesized via Friedlander annulation using Br?nsted acid silica-based sulfonic acid as a modified catalyst under solvent-free conditions at room temperature. This efficient procedure has the advantages of giving the target compounds in high yields, short reaction times, simple workup procedure, reusability of the catalyst, and environmentally benign conditions.

The purpose of conducting this research is to establish a conceptual model to improve the performance of new product development in organizations regarding variables of disruptive innovation, team vision, knowledge management, and fuzzy-front end. In this research, the structural equation modelling (SEM) is used to study the model. Also, the explanatory and confirmatory factor analysis are used to extract dimensions of fuzzy-front end and disruptive innovation variables. Research data have been gathered from 109 experts of development and research department of Iran Khodro manufacturing company. The results of research show that disruptive innovation may have very impressive effects on new product development performance. Also, team approach has direct effect on fuzzy-front end. On the other hand, knowledge management has a key role in new product development and organizations can increase the efficiency of new product development by managing their knowledge and sharing them and guarantee the organization success.

In the present paper, the differential transformation method is employed to develop a semi-analytical solution for free transverse vibration of single-walled carbon nanotube (SWCNT) with arbitrary boundary conditions. The small scale effect is taken into consideration via Eringen’s nonlocal elasticity theory while the transverse shear deformation effects and rotary inertia are taken into account in presented Timoshenko beam theory. Through variational formulation and the Hamilton & apos; s principle the governing differential equations and the boundary conditions are derived and then solved by a semi-analytical method called differential transformation method (DTM) for various frequency modes of beams and different edge conditions. Comparisons made between the present results and results reported by well-known references for special cases treated before, have confirmed accuracy and efficiency of the presented approach. The effects of several parameters such as transverse shear deformation effects, slenderness ratios, boundary conditions and small scale on vibration characteristics of SWCNT are examined. The present study illustrates that the vibration characteristics of an SWCNT are strongly dependent on the small scale parameters.
