in this research the asymmetric and non-linear correlation between the market returns and trading volume variables has modeled with the dcc-garch approach; and the impacts of market shocks, weekend and calendar effects on the market returns and trading volume are surveyed. the estimation results of parameters of the model by the maximum likelihood method show that previous day’s market return h...
Background and Aim: Environmental health impact assessment of industrial estates will help greatly in better planning for sustainable development and reducing disease risk in a community. The objective of this study was to assess the positive and negative effects of establishing an industrial estate in Jovein, Sabzevar, Iran in 2006-7 and suggest managerial strategies to reduce undesirable envi...
An ontology for representing operating, safety and control procedures is proposed in this paper that supports diagnosis based on following these procedures and combining observed malfunctions with Failure Mode and Effects Analysis (FMEA) information. The procedure ontology is defined within interconnected components of the process plant, diagnostic analysis (where the FMEA is described) and pro...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
Background and purpose: Health Impact Assessment (HIA) evaluates positive and negative consequences of development on human health, which is recently proposed in Iran. Human health involves a wide range of factors, therefore, predicting and estimation of their effects require convenient and efficient tools. Materials and methods: In this case study, data was collected and a database on regiona...
the impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence ofcadmium (100 μm) were investigated. inhibitory effects of cadmium on seedling growth resulted in reduced shoot and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars contents and a low rate of lipid peroxidation. results indic...
Strategies to enhance local adaptation capacity are needed to mitigate climate change impacts and to maintain regional stability of food production. The objectives of this study were to simulate the climate change effects on phenology stages, potato production in the future and to explore the possibilities of employing planting dates and various varieties (Agria, Arinda and Santeh) as mitigatin...
Using life satisfaction as a direct measure of individual utility has become popular in the empirical economic literature. In this context, it is crucial to know what circumstances or changes the measure is sensitive to. Is life satisfaction a volatile concept that is affected by minor changes in life circumstances? Or is it a reliable measure of personal happiness? This paper will analyze the ...
H. Gołaś, A. Mazur, B. Mrugalska, Faculty of Engineering Management, Poznan University of Technology, Poznan, Poland The aim of the paper is to highlight the significance of implication of risk analysis and quality control methods for the improvement of parameters of lead molding process. For this reason, Fault Mode and Effect Analysis (FMEA) was developed in the conceptual stage of a new produ...
