S Aalami,V Nikoui,M Irani,A Bakhtiarian
Tehran University Medical Journal , 2012,
Abstract: Background: There are conflicting reports about zinc, a trace element, in the pathogenesis of hypertension and other cardiovascular diseases. The aim of this study was to evaluate the role of zinc in high blood pressure.Methods: We conducted this study on 80 patients with primary (idiopathic) hypertension and 80 normotensive people with similar age who attended to Tehran Heart Center between 2007 and 2008. We examined the effect of zinc concentration on blood pressure in both sexes in four age groups (41-50, 51-60, 61-70 and 71-80 years old). We measured plasma zinc concentration by atomic absorption.Results: The mean plasma zinc concentrations were 0.456±0.04 μg/ml and 0.551±0.055 μg/ml in patients with hypertension and in normotensive people, respectively, (P≤0.05). Nevertheless, the mean plasma zinc concentrations were 0.494 μg/ml and 0.486 μg/ml in men with and without hypertension, respectively. The mean plasma zinc concentrations of women with and without hypertension, respectively were 0.415 μg/ml and 0.596 μg/ml, showing a significant difference between two groups (P≤0.001). Moreover, there was a significant difference in plasma zinc concentration between hypertensive and normotensive people in 51 to 60 years age group (P≤0.05), but difference were not significant between other age groups.Conclusion: The results of this study revealed the relationship between the decrease in plasma zinc concentration and increase in blood pressure in women and in the men aged 51 to 60 years.

OCCIPITAL WAR TRAUMA AND VISUAL FIELD DEFECTS
ZAHRA AALAMI-HARANDI,HORMOZ CHAMS
Acta Medica Iranica , 1986,
Abstract: Seven cases of visual field defects, caused by wartrauma were seen at Farabi Eye Hospital. None were referred by a neurologist. Four patients had 20/20 visions with normal fundi. One had 12/20, in both eyes, with normal fundi. Two patients presented fundus changes."nThe visual field defects were seen in all these seven patients. Four had homonymous hemianopia, one had bilateral field restriction, one patient had homonymous quadrianopia, one had unilateral restriction of the visual field, and the last one had bilateral loss of the inferior fields. The Cat-scan of six patients indicated the lesion of occiput and occipital lobe. One patient had a diffuse cerebral lesion.
Comparison of Four Distributions for Frequency Analysis of Wind Speed
Sabereh Darbandi,Mohammad Taghi Aalami,Hakimeh Asadi
Environment and Natural Resources Research (ENRR) , 2012, DOI: 10.5539/enrr.v2n1p96
Abstract: The increase in negative effects of fossil fuels on the environment has forced many countries to use renewable energy sources, especially wind energy. Wind speed is the most important parameter of the wind energy. Probability distributions are useful for estimating wind speed because it is a random phenomenon. This study analyzes wind speed frequencies using wind data from Tabriz synoptic station in Iran. Four different distributions are fitted to the maximum annual wind from station, and parameters of the distributions are estimated using the method of maximum likelihood and the method of moments. Calculations are performed with Mathematica, a computer algebra system developed by Wolfram Research. The advantage of using this software is that the symbolic, numerical, and graphical computations can be combined and that all quantities can be accurately calculated; in particular, there is no need to resort to any approximate methods for the calculation of quantiles. There is a ready-to-use command for calculating quantiles from distributions that are built in Mathematica, while for other distributions they can be easily and accurately calculated by inverting the cumulative distribution functions or by solving nonlinear equations where the inversion is not possible. The best distribution is selected based on the root mean square error (RMSE), the coefficient of determination (R2), and the probability plot correlation coefficient (PPCC). The results indicate that the best performance can be obtained by the Gamma distribution.
Public and Private Cultural Expenditure on the Economic Growth in Iran

International Journal of Academic Research in Business and Social Sciences , 2013,
Abstract: This paper try to find the effect of public and private cultural expenditure on the economic growth in Iran and determine the most important factor. Statical analysis and econometrics was performed for investigation of public and private cultural expenditure roles on economic growth using Kab-Daglus productional function and calculated according to Statistical Center of Iran and Central Bank of the Islamic Republic of Iran data. The results showed that labours, capital and cultural expenditure has positive effect on economic develoment, however the production tendency of labours has fist ranking between entities, it means that manpower is the most effective factor on the economic growth. Capital is the second factor and the cultural expenditure is the last effective factor. In fact, the production tendecy of Public and private sectors of culture is less than production tendecy of capital and labours. And the production tendecy of private sector is larger than public one. It means the effect of cultur expenditure of families on economic growth is more than the government cultural expenditure.

Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.66086
Abstract: Let \"\" be an injective function. For a vertex labeling f, the induced edge labeling \"\" is defined by, \"\" or \"\"; then, the edge labels are distinct and are from \"\". Then f is called a root square mean labeling of G. In this paper, we prove root square mean labeling of some degree splitting graphs.
A Parameter Estimation Model of G-CSF: Mathematical Model of Cyclical Neutropenia  [PDF]
S. Balamuralitharan, S. Rajasekaran
American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.21002
Abstract: We investigate the FFT (Fast Fourier Transform) model and G-CSF (granulocyte colony-stimulating factor) treatment of CN (Cyclical Neutropenia). We collect grey collies and normal dog’s data from CN and analyze the G-CSF treatment. The model develops the dynamics of circulating blood cells before and after the G-CSF treatment. This is quite natural and useful for the collection of laboratory data for investigation. The proposed interventions are practical. This reduces the quantity of G-CSF required for potential maintenance. This model gives us good result in treatment. The changes would be practical and reduce the risk side as well as the cost of treatment in G-CSF.

Rain Attenuation at Terahertz  [PDF]
S. Ishii
Wireless Engineering and Technology (WET) , 2010, DOI: 10.4236/wet.2010.12014
Abstract: Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R. Measurements of Terahertz wave taken at 313 GHz (0.96 mm) were compared with our calculations. Results showed that the propagation experiment was in very good agreement with a calculation from the specific attenuation model for use in prediction methods by ITU-R.
