Journal of Human Resource and Sustainability Studies (JHRSS) , 2017, DOI: 10.4236/jhrss.2017.51002
Abstract: The conception and use of work teams have been one of the main subjects of management researches for the last few decades and in the past years many developments have happened in the kinds and usage of them, which have improved the condition of organizations and human resources management. Our objective in this paper is to observe the formation of work teams and how they affect human resources excellence. Finding new and creative solutions for todays intricate situations is becoming more and more difficult and employees can’t solve them on their own anymore and this shows and bolds the importance of teamwork and forming work teams. The main objective however in this paper is to evaluate the effect of 5 main characteristics of work teams (which are team structure, leadership, control, mutual support and communication) on the 3 main characteristics of human resources excellence (which are delegation, motivation and team work) in Torang Darya Shipping Company. To do so, 200 personnel at the department were randomly selected from 450 personnel by Cochran sample size formula and answered to the research made questionnaire derived from[1][2] and[3]. The content validity of the questionnaire has been confirmed by the experts and academicians and the reliability has also been confirmed
Pathology of Barriers to Sharing Knowledge in Project Management and Ranking Them by AHP Method  [PDF]
Ebrahim Kalani, Ehsan Kamrani
Journal of Human Resource and Sustainability Studies (JHRSS) , 2017, DOI: 10.4236/jhrss.2017.51007
Abstract: Although knowledge management is a necessary part of strategic development of organizations, resources and improvement in competition, since it is always seen just as a temporary solution, most of related experiences have faced failure. Moreover since projects are mostly temporary and after they are done some of the main team members leave the company, this means the knowledge goes with them so this will cost future projects more money and time. In the present study we will try to find the main barriers for knowledge transmission and to rank them by statistical method of Analytic Hierarchy Process (AHP). In the end it comes to conclusion that despite the existence of the Project Management Body of Knowledge (PMBOK), it has been overlooked. The main barriers are the lack of organizational culture of preserving and sharing the knowledge and lack of trust and appreciation for using it throughout the company.
The Pathology of the Hindrance Factors Impeding the Application of Value Engineering in the Construction Industry in Iran and Ranking Them by Use of Analytical Hierarchy Process  [PDF]
Ebrahim Kalani, Reza Baradaran Kazem-Zadeh, Ehsan Kamrani
Journal of Human Resource and Sustainability Studies (JHRSS) , 2017, DOI: 10.4236/jhrss.2017.51006
Abstract: Nowadays due to the importance of value engineering, many researches have been done about it and application of it in engineering subcategories especially civil engineering. Researches have either paid attention to the structure of value engineering or to the procedures of getting it done or to mixing it with other managerial tactics like risk management, cost management, quality management, or to the diagnosis of the problems in the procedure of value engineering. However, the present research is about the diagnosis of the barriers against application of value engineering in civil engineering projects in Iran with collecting data and experts’ views and engineers and professors and also application of statistical and AHP approach. The findings of this research include: diagnosis and ranking of the barriers against development and application of value engineering in civil projects with help of AHP-categorizing applicants of value engineering in terms of their field of work in civil engineering, their level of education, their experience and visualizing the amount of application of value engineering in today`s civil projects. It can be reached from data that the most important barrier is lack of the culture and aspiration for thrift. It can be reached from the research that the most important barriers against application of value engineering are lacking the related culture and incentive for thrift and good use of resources. Of course the activities of groups like value engineers club, civil engineers club, office of planning and controlling of presidency are most important in making applicants keen on using the value engineering.

Selection of Investment Basis Using Neural Networks in Stock Exchange  [PDF]
Ebrahim Kalani, Alireza Elhami, Reza Baradaran Kazem-Zadeh, Ehsan Kamrani
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.83036
Abstract: A generalization is considered on the standard Marvowitz mean-variance model, which includes some limitative limbs. These restrictions guarantee the investment in a certain number of assets and limit the amount of capital that must be invested in any asset (stock). When the Markovitz mean-variance model is considered, the basket selection problem is a quadratic programming problem. But if this model is generalized with limitations, then the basket selection problem will be transformed into a quadratic programming and numerical design. In this recent model, there is no algorithm and method that can solve the basket selection problem optimally. In this case, the use of the heuristic algorithm is essential. Here in this paper a special neural network model has been used. The Hopfield network has been used to optimize some of the other optimization problems and it is used to solve the portfolio selection problem.

Ebrahim Kalani, Alireza Elhami, Mahshid Mashreghi, Reza Baradaran Kazem-Zadeh, Ehsan Kamrani
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.83035
Abstract: With the new technology, organizations increasingly recognize the importance of managing customer relationships, and many of them have been deployed to customer relationship management (CRM) in order to serve customers better and build close relationships with them. On the other hand, the recognition of valued customers and their management has become an important issue. In today’s world, the business market is a complex network of tangible and intangible value relationships whose identification and optimal management is important. If these relationships are not optimally managed, it can lead to a great deal of harm to the organization and; on the other hand, if these relationships can be properly identified and managed, they can organize huge profits with the least cost. In this article, the target organization that focuses on the network, as well as its corporate clients, has been reviewed, and a model for explaining customer strategy for implementing CRM in a company (Saba Corporation in Iran) as an example has been presented. Further, on the characteristics of its customers, the organization’s policy has also been implemented. To do this, first, corporate customers focus on the value they focus on (customer lifetime value or CLV), and then the value chain will be implemented across the different segments of the corporate customer focus. By implementing the value chain among the various sections of the corporate customers, the hub can design suitable marketing programs for managing value paths and allocate appropriate budgets for each path.
The importance of endothelin-1 for microvascular dysfunction in diabetes

Vascular Health and Risk Management , 2008,
Abstract: Majid KalaniDepartment of Clinical Sciences Karolinska Institutet, Dept of Cardiology, Danderyd Hospital, Stockholm, SwedenAbstract: Most of the late diabetic complications such as retinopathy, nephropathy, and neuropathy, have their basis in disturbed microvascular function. Structural and functional changes in the microcirculation are present in diabetes mellitus irrespective of the organ studied, and the pathogenesis is complex. Endothelial dysfunction, characterized by an imbalance between endothelium-derived vasodilator and vasoconstrictor substances, plays an important role in the pathogenesis of diabetic microangiopathy. Increased circulating levels of endothelin-1 (ET-1), a potent vasoconstrictor peptide, has been found in patients with diabetes, and a positive correlation between plasma ET-1 levels and microangiopathy in patients with type 2 diabetes has been demonstrated. In addition to its direct vasoconstrictor effects, enhanced levels of ET-1 may contribute to endothelial dysfunction through inhibitory effects on nitric oxide (NO) production. Vascular endothelial dysfunction may precede insulin resistance, although the feature of insulin resistance syndrome includes factors that have negative effects on endothelial function. Furthermore, ET-1 induces a reduction in insulin sensitivity and may take part in the development of the metabolic syndrome. In the following, the mechanisms by which ET-1 contributes to the development of diabetic microangiopathy and the potentially beneficial effect of selective ETA receptor antagonists are discussed.Keywords: endothelin-1, diabetes mellitus, microcirculation, diabetic microangiopathy, ETA-receptor antagonist

Abstract: t of supercritical fluid density on nanoencapsulated drug particle size using the supercritical antisolvent method Original Research (3115) Total Article Views Authors: Kalani M, Yunus R Published Date April 2012 Volume 2012:7 Pages 2165 - 2172 DOI: http://dx.doi.org/10.2147/IJN.S29805 Received: 09 January 2012 Accepted: 02 February 2012 Published: 27 April 2012 Mahshid Kalani, Robiah Yunus Chemical and Environmental Engineering, Faculty of Engineering, University Putra Malaysia, Selangor Darul Ehsan, Malaysia Abstract: The reported work demonstrates and discusses the effect of supercritical fluid density (pressure and temperature of supercritical fluid carbon dioxide) on particle size and distribution using the supercritical antisolvent (SAS) method in the purpose of drug encapsulation. In this study, paracetamol was encapsulated inside L-polylactic acid, a semicrystalline polymer, with different process parameters, including pressure and temperature, using the SAS process. The morphology and particle size of the prepared nanoparticles were determined by scanning electron microscopy and transmission electron microscopy. The results revealed that increasing temperature enhanced mean particle size due to the plasticizing effect. Furthermore, increasing pressure enhanced molecular interaction and solubility; thus, particle size was reduced. Transmission electron microscopy images defined the internal structure of nanoparticles. Thermal characteristics of nanoparticles were also investigated via differential scanning calorimetry. Furthermore, X-ray diffraction pattern revealed the changes in crystallinity structure during the SAS process. In vitro drug release analysis determined the sustained release of paracetamol in over 4 weeks.
