Management Science Letters , 2012,
Abstract: In an environment, which is highly competitive and everything changes rapidly, managers of organizations face with problems such as how to identify important factors preventing organizations from optimum use of available resources and capacities and invest more on key factors. To achieve this goal, we need to develop an effective strategy map for organizations. The strategy map is a constructional and expanding procedure to identify relationships among all the organization's strategic goals, which play a key role in achieving competitive advantage. Undoubtedly, representing a model to identify and to evaluate the important items for each of available goals in strategy map of each organization is a significant help for management to access higher competition benefits. In this paper, strategic objectives in the strategy map of one of the best producer of electric auto part makers in Iran called Electric Vehicle Co. East are evaluated based on balanced score card perspective and to assign appropriate values to available factors we use a hybrid method consist of AHP technique with Fuzzy logic.

Management Science Letters , 2012,
Abstract: In global market, factors such as precedence of competitors extending shave on market, promoting quality of services and identifying customers' needs are important. This paper attempts to identify strategic services in one of the biggest governmental banks in Iran called Melli bank for getting competition merit using Kano and SERVQUAL compound models and to extend operation quality and to provide suitable strategies. The primary question of this paper is on how to introduce high quality services in this bank. The proposed model of this paper uses a hybrid of three quality-based methods including SERVQUAL, QFD and Kano models. Statistical society in this article is all clients and customers of Melli bank who use this banks' services and based on random sampling method, 170 customers were selected. The study was held in one of provinces located in west part of Iran called Semnan. Research findings show that Melli banks' customers are dissatisfied from the quality of services and to solve this problem the bank should do some restructuring to place some special characteristics to reach better operation at the heed of its affairs. The characteristics include, in terms of their priorities, possibility of transferring money by sale terminal, possibility of creating wireless pos, accelerating in doing bank works, getting special merits to customers who use electronic services, eliminating such bank commission, solving problems in least time as disconnecting system, possibility of receiving foreign exchange by ATM and suitable parking in city.

Dynamic Simulation of Volume Fraction and Density Solid Phase Effect on Phase Hold-Up in 3 Phase Fluidize Bed Column through CFD  [PDF]
Mohammad Ali Salehi, Ali Basiry
Engineering (ENG) , 2015, DOI: 10.4236/eng.2015.71003
Abstract: The gas-liquid-solid fluidized bed has emerged in recent years as one of the most promising devices for three-phase operation. Selection and design is one of them in parameter in the performance of three phase system. This paper focuses on volume fraction and density effect on the phases hold-up in a 3 phase fluidize bed column containing liquid phase with 100 cm height and 20 cm diameter, in this case the solid phase with 0.15, 0.25, 0.35 volume fraction and density 2470, 3000, 4000, 5000 m3 dispersion into liquid phase and the gas phase enter the column through a sparger of 2 cm diameter with 0.02 m/s velocities. The results show as the solid phase volume fraction increases from 0.02 to 0.08 m/s. The gas hold-up decreases and solid hold-up increases. Solid phase density increases, so solid phase hold-up decreases and gas hold-up decreases.
Power Transformer Top Oil Temperature Estimation with GA and PSO Methods  [PDF]
Mohammad Ali Taghikhani
Energy and Power Engineering (EPE) , 2012, DOI: 10.4236/epe.2012.41006
Abstract: Power transformer outages have a considerable economic impact on the operation of an electrical network. Obtaining appropriate model for power transformer top oil temperature (TOT) prediction is an important topic for dynamic and steady state loading of power transformers. There are many mathematical models which predict TOT. These mathematical models have many undefined coefficients which should be obtained from heat run test or fitting methods. In this paper, genetic algorithm (GA) and particle swarm optimization (PSO) are used to obtain these coefficients. Therefore, a code has been provided under MATLAB software. The effects of mentioned optimization methods will be studied on improvement of adequacy, consistency and accuracy of the model. In addition these methods will be compared with the Multiple-Linear Regression (M-L R) to illustrate the improvement of the model.

Hannan Mohammad Ali
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.32019
Abstract: The pathology of patellar tendinopathy and the mechanisms of pain are poorly understood. The most popular treatment modality is the Eccentric overload Exercise. However, there is insufficient evidence to recommend a specific protocol and yet it is the most commonly used treatment modality. The aim of this case study is to present the possible mechanisms of pain and a treatment approach on a patient who was diagnosed as having patellar tendinopathy. It is suggested that hyper extension of the knee might be the source of patellar tendon pain in this patient. Following a course of pulsed short wave diathermy the patient was symptom free and remained so at 6 month review. Further studies to evaluate effectiveness of pulsed short wave diathermy is suggested.

Abstract: Purpose: The purpose of this review was to discuss the status of evidence related to the assessment of readiness of healthcare facilities for e-health initiatives implementation, specifically the common Electronic Health Record (EHR) systems. Methods: An integrative review approach was utilized. The databases of Google Scholar, Scopus, Science Direct, PubMed, Medline, CINAHL, Ovid, ProQuest, and EBSCO host were searched for related evidence published between 2000 and 2018. Results: Seventeen studies were included in the current review. In terms of methodological approach, the included studies were 7 correlational studies, 5 review papers, 4 qualitative papers, and one mixed methods study. At the current integrative review, the themes of complex healthcare change, and the main theme of e-health readiness assessment were identified. Conclusion: Assessing and reporting the levels of readiness for EHRs implementation are highly recommended as it has a high impact on the critically-needed adoption and usage of the implemented system. Selecting the right tool for the right audience to address readiness is essential in the assessment process which is recommended to be conducted early at the road map of the project implementation. Future research is recommended to address readiness for e-health initiatives at the different settings and different target populations including communities where the healthcare facilities functions and service receivers’ readiness.
Evaluating the Efficacy of Remifentanil-Propofol versus Isoflurane in Reducing Blood Loss with Considering Depth of Anesthesia during Endoscopic Sinus Surgery  [PDF]
Mohammad Ali Haghbin, Hossein Hakimzadeh, Mohammad Shabani
Neuroscience & Medicine (NM) , 2013, DOI: 10.4236/nm.2013.42009
Abstract:

Several methods have been suggested to decrease bleeding during surgery, one of which is the usage of hypotensive anesthetic agents. Endoscopic Sinus Surgery (ESS) is one of the surgeries which need a clear field and the amount of bleeding profoundly impacts the ability of surgeons. Current study was designed to evaluate the effect of remifentanil combined with propofol versus Isoflurane on blood loss during ESS and its possible interaction with Depth of Anesthesia. Fifty one patients comprising 15 females and 36 males undergoing ESS were chosen for this study. One group received propofol and remifentanil to induce and maintain anesthesia and the second group received Isoflurane. Mean Arterial Blood Pressure (MAP), Depth of Anesthesia and total blood loss were recorded for the patients of both group. Data were analyzed using t-test, Repeated Measures ANOVA and Pearson’s correlation. P < 0.05 was considered statistically significant. Both agents induced hypotension during surgery. No significant difference was observed in total blood loss between two groups. DA was decreased in both groups, but no significant correlation was found between DA and MAP or DA and blood loss. There is no significant difference between remifentanil combined with propofol and Isoflurane in decreasing blood loss during ESS, thus we suggest usage of hypotensive anesthetic agent regardless of its type is ESS.

Heavy Metals Distribution and Their Correlation with Clay Size Fraction in Stream Sediments of the Lesser Zab River at Northeastern Iraq  [PDF]
Abbas Rasheed Ali, Mohammad Jamil Ali Talabani
Journal of Geoscience and Environment Protection (GEP) , 2018, DOI: 10.4236/gep.2018.64006
Abstract: Heavy metals (i.e. Cr, Co, Ni, Cu, Zn, Rb, Sr, Ba, Pb, V and Ga) distribution and their correlation with clay fraction were investigated. Fifteen samples of stream sediments were collected from the Lesser Zab River (LZR), which represent one of three major tributaries of the Tigris River at north-eastern Iraq. Grain size distributions and textural composition indicate that these sediments are mainly characterized as clayey silt and silty sand. This indicates that the fluctuation in the relative variation of the grain size distribution in the studied sediments is due local contrast in the hydrological conditions, such as stream speed, energy of transportation and geological, geomorphological and climatic characterizations that influenced sediments properties. On the other hand, clay mineral assemblages consist of palygorskite, kaolinite, illite, chlorite and smectite, which in turn reveals that these sediments were derived from rocks of similar mineralogical and chemical composition as it is coincided with other published works. The clay mineral assemblages demonstrate that major phase transformations were not observed except for the palygorskite formation from smectite, since the minerals pair exhibit good negative correlation (-0.598) within the Lesser Zab River (LZR) sediments. To determine interrelation between the heavy metals and the clay fractions in the studied samples, correlation coefficients and factor analysis were performed. Heavy metals provide significant positive correlation with themselves and with Al2O3, Fe2O3 and MnO. In addition, the results of factor analysis extracted two major factors; the first factor loading with the highest percent of variation (60%) from the major (Fe2O3, Al2O3 and MnO in weight %), heavy metals and clay fraction. While the second factor with the (14%) of variance includes Cr and silt fraction, which indicate the affinity of the heavy metals being adsorbed onto solid phase like clay particles. These observations suggest that a common mechanism regulates the heavy metal abundance, and that their concentrations are significantly controlled by fine clay fractions, clay mineral abundance and ferro manganese oxides-hydroxides.

Pooneh Dehghan, Ali Zahiri, Mohammad Ali Karimi, Mohammad Hossein Ghadiani
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.37006
Abstract: Leontiasis ossea is a rare medical condition which is characterized by an overgrowth of the facial and cranial bones secondary to chronic renal failure and secondary hyperparathyroidism. We reported a case of leontiasis ossea with history of secondary hyperparathyroidism due to end-stage renal disease on regular hemodialysis. A 37-year-old female with end-stage renal disease from lupus disease on regular hemodialysis complaining of progressive facial deformity for two years causing dyspnea, dental malocclusion and dysarthria with the final diagnosis of uremic leontiasis ossea. It is important to recognize features of leontiasis ossea, as it may result in life-threatening upper airway obstruction and compressive cranial neuropathy while after parathyroidectomy, facial changes can be stabilized or improved mildly.
