Factors Affecting SOC and NPK in the Rangeland, Forest and Agriculture; Case Study Halashi Catchment, Kermanshah, Iran  [PDF]
Shohreh Abdolmohamadi, Alireza Ildoromi, Mosayeb Heshmati
Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.513002
Abstract: Land use change causes soil disturbance and thereby considerable soil nutrients depletion and environmental impacts. This research was conducted in Halashi catchment, Kermanshah, Iran to compare the variation of soil NPK and SOC in Agricultural Lands (AL), Rangelands (RL) and Forest lands (FL). The coverage of ground surface including plant crown, stone and litter was estimated in field by using quadrate plot (1 m2). Soil sampling and the analysis were carried out for each land use during April and May, 2015. Inter-rill, rill, gully and landslide were found as the dominant erosion features. The ANOVA analysis explored no considerable differences for soil texture, pH and Electrical Conductivity (EC). High clay and silt content induced clayey and silty soil that means Soil Organic Carbon (SOC) level in the AL, RL and FL were 1.14%, 1.45% and 2.13%, respectively, showing significant (p ≤ 0.05) different from each other among them. The respective values of total N in the AL, RL and FL were 0.14, 0.14 and 0.18 mg/kg, indicating significant decrease in the AL and RL. The respective mean avails P and exch. K in the AL, RL and FL were 15.72, 11.44, 11.38; 342.5, 375.0 and 374.5 mg/kg. Crop residues burning and tillage practicing cause depletion of SOC and NPK in AL, while as compared with FL, lower vegetation canopy and litter in the RL promotes soil nutrients and SOC lost due to overgrazing and converting to rain-fed lands. As a conclusion, rangeland was the intermediate site in terms of soil nutrient and SOC stock in the Halashi.

Abstract:

Accelerated soil erosion is anthropogenic phenomenon and a major worldwide environmental problem. It mainly leads to removal of the clay minerals and soil nutrients and thereby reduces soil fertility because of mineralogical influence on the soil. The objectives of this study were to identify the dominant soil and rock minerals and the influences of mineralogical properties on soil erosion features. This study was conducted at the Merek watershed, located in Kermanshah, Iran. There are different geological formations comprising limestone, sandstone, radiolarite, flysch, shale and marl. The border of each formation was mapped based on geology map and was checked in the field, using GPS and digitized by GIS software (ILWIS 3.5). The erosion feature map was prepared through remotely sensed data (Landsat ETM+ 2002, Path/Row and acquired date). About 300 soil and 28 rock samples were collected from the study area for soil and mineralogy analysis. Result shows that inter-rill, rill and snow erosion were occurred mainly at soil from Sarvak, Ilam and Gurpi Formation which are mainly containing calcite, dolomite, quartz and caolinite minerals giving moderate soil erosion intensity (5 - 10 t·ha1·yr–1). Whereas mica/smectite was dominant clay mineral of soil from Older Terraces resulting in gully erosion and considerable 12.90 t·ha–1·yr–1 soil loss. Furthermore, smectite was found as the dominant clay mineral from both soil and parent material of Kashkan Formation (marls material) contributing to landslide occurrence and severe annual soil erosion (16.6 t·ha–1·yr–1). This study revealed that both soil erosion feature and intensity potentially are affected by mineralogical properties.

Statistics , 2015,
Abstract: In this paper, we consider the problem of multiuser detection in non-Gaussian channels. We propose a new penalty function for robust multiuser detection. The proposed detector outperforms other suboptimal detectors in non-Gaussian environment. Analytical and simulation result shows the performance of the proposed detector compare to other detectors.
Wheezing in Pediatric Age Group
A Heshmati
Iranian Journal of Pediatrics , 2000,
Abstract: Audible sounds associated with breathing can provide important diagnostic information on the site and nature of respiratory disease. Wheezing is a common sound and is usually indicative of obstruction of the intra-thoracic airways-usually medium or smaller airways-but occasionally is due to localized narrowing of a major bronchus or even the trachea. This article discusses the important causes of wheezy breathing from a pathophysiological standpoint.

Abstract: One of the important dimensions of violence is suicide, or violence directed toward self that many people suffer from nowadays. In the meantime, adolescents and especially girls are more likely to be harmed. The purpose of this study was to evaluate the effect of group training with non-violent communication (NVC) method on suicidal ideations and coping with stress styles of adolescent girls. The target community in this research was availably selected from the charity centers of Tehran suburbs. In this study, 15 adolescent girls were in the experimental group and 15 in the control group. The criteria for entering the research were students aged 11 to 19 years and the vulnerable socio-economic income. Eight training sessions of NVC were presented for the experimental group in the pre-test and post-test intervals, while no intervention was performed for the control group. Data collection instruments were Beck’s scale for suicidal ideation (BDI) and Endler & Parker’s coping inventory for stressful situations (CISS). After statistical analysis, the effectiveness of this training was investigated on dependent variables by multivariate analysis of covariance. Eventually, the results showed a significant difference between the experimental and control groups (p < 0.05). The finding of the study showed that NVC training can reduce suicidal ideations in adolescent girls who are socially and economically vulnerable. According to the findings, non-violent communication training has a higher effect on emotion-focused coping style compared to other stress coping styles.
Economies of Scale in the Tunisian Industries

Abstract: To date, empirical investigations of trade liberalization, under the conditions of increasing returns to scale (IRS) and imperfect competition (IC), have either assumed or imposed the market and productive structures necessary for such a model. However, of the recent IRS/IC models used to simulate the effects of trade liberalization, none have empirically tested for the presence of increasing return to scale prior to the analysis. With Tunisian data (1971-2004) and rigorous test procedures, we investigate evidence of IRS at the industry level. Using an econometric approach based on the estimation of the translog cost function and its associated cost share equations, we identify the sectors characterized by increasing returns to scale. Analysis of the results shows that specification of the model is sensitive to inclusion of time trend representing technology. For most sectors, the model accounting for technology did not fit the data well.Estimation results without time trend interactions are different and most sectors show signs of increasing returns to scale.

Acta Medica Iranica , 1997,
Abstract: litis study is based on embryotoxic effects of ethanol on embryos and discussing the morphologic and hhtahtgic changes and defects an mouse. Tlie female animals were divided in three groups. Hie first group untreated as a control group but the second and third group received 10% and 20% solutions of ethanol respectively. Animals get use to certain level of ethanol solution and in the 10th day, the pregnancy period has been started. Then on the 19th day of gestation, the embryos were taken out from their mother's uterus and were examined for morphologic, histologic and skeletal disorders. In the first examination, the major defect was weight and length reduction in the second and third groups. these deffects, were severe in the second group in compare to third group that might be related to little consumption of the ethanol solution, due to bitter taste. In conclusion the teratogenic effect of alcohol on skeleton and joint is clear.
Alternative Composite Lisbon Development Strategy Indices: A Comparison of EU, USA, Japan and Korea
Almas Heshmati,JongEun Oh
The European Journal of Comparative Economics , 2006,
Abstract: This study addresses the measurement of two composite Lisbon strategy indices that quantifies the level and patterns of development for ranking countries. The first index is nonparametric labelled as Lisbon strategy index (LSI). It is composed of six components: general economics, employment, innovation research, economic reform, social cohesion and environment, each generated from a number of Lisbon indicators. LSI by reducing the complexity of the set of indicators, it makes the ranking procedures quite simple. The second and parametric index is based on principal component analysis. Despite the difference in the ranking by the two indices, it is shown that the United States outperformed most EU-member states. Our investigations also show evidence of significant dynamic changes taking place, as the countries of the Union struggle to achieve the Lisbon goals. The necessity of a real reform agenda in several old and new members and candidate countries emerges from our analysis. We briefly refer to two important European phenomena emerging from our data analysis and discuss the possible lessons learned from the Korean development strategy

Mohammad Nabi Shahiki Tash,Mosayeb Pahlvani
International Journal of Academic Research in Business and Social Sciences , 2012,
Abstract: Non-linear dynamic systems show different behaviors so that they can be applied to interpretation many of the seemingly random economic phenomena. The chaos theory provides a new approach to investigating the changes trend of non-linear dynamic systems in monetary and financial markets. This paper investigates the behavior of economic growth in Iran using the chaos theory, BDS and bootstrap test, maximum Lyapunov exponent, the Hurst exponent and phase space reconstruction. The aim of this study is to examine whether economic growth has an independent identical distribution or follows from a non-linear (random or chaotic) process. The results of BDS test and the Hurst exponent indicates that economic growth has a non-linear process. The results of two chaotic tests includes maximum Lyapunov exponent and phase space reconstruction also confirmed the existence of chaos in GDP.
