Complexifier Versus Factorization and Deformation Methods For Generation of Coherent States of a 1D NLHO: I. Mathematical Construction
R. Roknizadeh,H. Heydari
Physics , 2013, DOI: 10.1142/S0219887813500564
Abstract: Three methods: complexifier, factorization and deformation, for construction of coherent states are presented for one dimensional nonlinear harmonic oscillator (1D NLHO). Since by exploring the Jacobi polynomials $P_n^{a,b}$'s, bridging the difference between them is possible, we give here also the exact solution of Schr\"odinger equation of 1D NLHO in terms of Jacobi polynomials.

G.H. Heydari,S. Moslemi,Q. Heydari,A. Kebriaei
Journal of Medical Sciences , 2006,
Abstract: In this study we have assessed the short-term effectiveness of diabetes education on BMI reduction, changes on (FBS, Chol, TG Rates) of type 2 diabetic patients in relation to proper nutrition. A sample of 125 diabetic patients was systematic randomly chosen. The method chosen for collecting the information (Data) was through questionnaires and laboratory tests (fasting blood sugar, total cholesterol, TG) that was conducted before educational programmes and after constantly education, finally the FBS, Chol, TG and weight were compared. The study showed significant improvements in several aspects of research. This study has shown a high level of illiteracy amongst our patients, which is of course common in developing countries. Diabetics did not gain weight and their relatives lost weight after nutrition curriculum. The mean fasting blood glucose before education was 216.27 mg %, whereas it fell to a mean level of 178.39 mg % after education. The patients had significantly lower serum cholesterol after 7 month education (172 mg %), p = 0.005. The present study clearly demonstrate the great benefits of diabetes self-care education. Most of these studies and our own, have been short term. We conclude that diabetes education is appropriate achievable and worthwhile. The challenge remains as to how to continue benefit long term.

M. Heydari,J. Freund,S. H. Boutcher
Journal of Obesity , 2012, DOI: 10.1155/2012/480467
Abstract: To determine the effect of a 12-week high intensity intermittent exercise (HIIE) intervention on total body, abdominal, trunk, visceral fat mass, and fat free mass of young overweight males. Participants were randomly assigned to either exercise or control group. The intervention group received HIIE three times per week, 20 min per session, for 12 weeks. Aerobic power improved significantly (<0.001) by 15% for the exercising group. Exercisers compared to controls experienced significant weight loss of 1.5 kg (<0.005) and a significant reduction in total fat mass of 2 kg (<0.001). Abdominal and trunk adiposity was also significantly reduced in the exercising group by 0.1 kg (<0.05) and 1.5 kg (<0.001). Also the exercise group had a significant (<0.01) 17% reduction in visceral fat after 12 weeks of HIIE, whereas waist circumference was significantly decreased by week six (<0.001). Fat free mass was significantly increased (<0.05) in the exercising group by 0.4 kg for the leg and 0.7 kg for the trunk. No significant change (>0.05) occurred in levels of insulin, HOMA-IR, and blood lipids. Twelve weeks of HIIE resulted in significant reductions in total, abdominal, trunk, and visceral fat and significant increases in fat free mass and aerobic power.
Impact of Mechanical Forces in a 25kA Current Injection Transformer
H. Heydari,S.M. Pedramrazi
Journal of Electrical Systems , 2007,
Abstract: Since Current Injection transformer (CIT) systems are within the major group of the standard type test equipments in electrical industry, their performances are very important. When designing a high current devices, there are many factors to be considered from which, unharmful effects of mechanical forces due to high current (25kA) passing through secondary winding of a CIT must be ensured. Since the electromagnetic forces is proportional to the square of current, up to the present time, as far as the authors are aware no report on impact of mechanical forces considerations for current injection devices has been made. This paper attempts to fill this void in our knowledge by considering various issues related to the mechanical forces in a 25kA CIT, using 2D electromagnetic fields (EMFs) simulation tools (Ansys 8.1) to calculate stray reactance fields and the mechanical forces in a single turn secondary winding of the CIT.
Inspection on Three Plant Spices as an Animal Forage Source in Mazandran Wetland
G. Heydari,A. Teimouri Yansari,H. Zali
Pakistan Journal of Nutrition , 2006,
Abstract: In order to evaluation of wetland plant spices as a forage source in animal nutrition, three species, Paspalum distichum, Sparganium erectum and Aeloropus litoralis that has vast cover in Mazandaran wetland was chosen. At the 30% of flowering, randomly, 3 kg of feed samples were taken and kept on -20oC, until that defreeze before chemical analysis. Chemical composition including crud protein (CP), crud fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), total digestible nutrients (TDN), digestible dry matter (DDM), predicted dry matter intake, relative forage value (RFV) and relative forage quality (RFQ) of feeds were calculated. Using two ruminal fistulated mature Zel sheep, NDF digestibility (% of NDF) were measured via in situ techniques. Dry matter, CP, CF, NDF, ADF, and ash content of three spices were significantly different. Aeloropus litoralis had the highest dry matter, CP, ADF, and ash, but Sparganium erectum had the highest CF, NDF. There were not significant different between NFC and ether extract content of three plant spices. Digestibility of NDF after 48-h ruminal incubation was significantly different and the values were 0.65, 0.63, and 0.66 % of NDF in Paspalum distichum, Sparganium erectum, and Aeloropus litoralis, respectively. However, digestible NDF (NDFD; % of NDF) had no difference in Paspalumdistichum, Sparganium erectum, and Aeloropus litoralis (45.68, 45.51 and 44.10% of NDF, respectively). TDN, DDM content of three spices and predicted DMI (% of BW) had not significant differences. The values of RFV and RFQ were significantly different in Paspalumdistichum, Sparganium erectum, and Aeloropus litoralis (118.08, 114.73 and 124.23; 143.26,116.32 and 136.27, respectively. It can be concluded that wetland grasses are high in NDF, but that fiber typically is highly digestible; therefore, wetland grasses may be evaluated more accurately when tested for RFQ instead of RFV.
Epidemiology of depression among infertile and fertile couples in Shiraz, Southern Iran
Ashkani H,Akbari A,Heydari S
Indian Journal of Medical Sciences , 2006,
Abstract: BACKGROUND: Depression is considered as one of the main psychological disorders associated with infertility. Depression may play a significant role in the life of infertile individuals, their infertility treatment follow-up and in their hopefulness for the future; it may also influence the intensity and continuousness of the mutual relationship of the affected couple. AIMS: This study was done to determine the depression rate and make a comparison between infertile and fertile couples with respect to the same. SETTING AND DESIGN: The depression rate was evaluated between two groups - infertile couples (case group) and fertile couples (control group). MATERIALS AND METHODS: Ninety-one infertile couples (cases) and 9l fertile ones (controls) were randomly enrolled in our study. Beck depression inventory (BDI) and demographic information were provided. STATISTICAL ANALYSIS: We used Chi-square, t-test; and one-way Analysis of Variance (ANOVA) was performed to find out significant difference between infertility duration in various couples and its effect on the score of depression. RESULTS: The BDI mean difference between infertile and fertile couples was significant (P=0.015). It was significantly more among couples with infertility from 1-3 years′ duration compared to those with infertility of 1-year duration or less. CONCLUSION: Regarding the high rate of depression among infertile couples, it seems necessary to pay more attention to infertility centers that offer psychological and psychiatric services.

H. Heydari Main,M. Saadi Mesgari
Journal of Applied Sciences , 2009,
Abstract: Landuse planning problems are categorized as complicated locational decision-making problems. This complexity makes us unable to solve such problems with common methods. It seems using intelligent systems such as expert systems and integrating those with decision support systems can help us to overcome with urban landuse planning problems. In this study, first it will be shown why a knowledge-based spatial decision support system is suitable for solving urban planning problems and EALUA that has been designed and developed by researcher with aforesaid architecture for encounter with urban problems will be introduced. Finally, result of using EALUA will be evaluated.
Generalized Chaplygin gas as geometrical dark energy
M. Heydari-Fard,H. R. Sepangi
Physics , 2007, DOI: 10.1103/PhysRevD.76.104009
Abstract: The generalized Chaplygin gas provides an interesting candidate for the present accelerated expansion of the universe. We explore a geometrical explanation for the generalized Chaplygin gas within the context of brane world theories where matter fields are confined to the brane by means of the action of a confining potential. We obtain the modified Friedmann equations, deceleration parameter and age of the universe in this scenario and show that they are consistent with the present observational data.
Gauss-Bonnet brane gravity with a confining potential
M. Heydari-Fard,H. R. Sepangi
Physics , 2007, DOI: 10.1103/PhysRevD.75.064010
Abstract: A brane scenario is envisaged in which the $m$-dimensional bulk is endowed with a Gauss-Bonnet term and localization of matter on the brane is achieved by means of a confining potential. The resulting Friedmann equations on the brane are modified by various extra terms that may be interpreted as the X-matter, providing a possible phenomenological explanation for the accelerated expansion of the universe. The age of the universe in this scenario is studied and shown to be consistent with the present observational data.
Anisotropic brane gravity with a confining potential
M. Heydari-Fard,H. R. Sepangi
Physics , 2007, DOI: 10.1016/j.physletb.2007.04.008
Abstract: We consider an anisotropic brane world with Bianchi type I and V geometries where the mechanism of confining the matter on the brane is through the use of a confining potential. The resulting equations on the anisotropic brane are modified by an extra term that may be interpreted as the x-matter, providing a possible phenomenological explanation for the accelerated expansion of the universe. We obtain the general solution of the field equations in an exact parametric form for both Bianchi type I and V space-times. In the special case of a Bianchi type I the solutions of the field equations are obtained in an exact analytic form. Finally, we study the behavior of the observationally important parameters.
