Human evolution and advancement in the field of science and technology has significantly given a steep rise in air pollution causing us to monitor them so that it does not surpass the ‘danger’ level. Though modern instruments provide us with accurate measurements, they are available with different principles and exist as separate instrument. This paper intends to combine all such instruments together to form a single instrument which would measure the major air pollutants in air. The paper includes an instrumentation design which can be used to measure the major pollutants in air. The monitoring of the basic pollutants like SO2, NO2, Carbon monoxides, hydrocarbons and dust are done via this instrument. Efforts are taken to propose a device which is cost efficient and accurate.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123481880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the maximum L-lactic acid yield and optical purity were obtained at pH 7.0 with 0.94 g/g and 100%, respectively. The optimum temperature was found to be 43°C, at which the lactic acid yield and maximum productivity were 1.0 g/g and 3.44 g/L/h, respectively.

Furthermore, the conceptual intension of such an approach emphasizes a new theoretical architectonics within which the scientific community assumes the promoted attitudes and strategies. Consequently, the scientific and technological area of the environment involves a reevaluation at a practical level from the perspective of psychology and epistemology corroborated with a new way of understanding the idea of human consciousness.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129655792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider a class of stochastic volatility (SV) models that incorporate the following features: correlations between the the monthly changes in level of ACDC growth rate and their volatility, heavy-tailed error distribution, jumps in observation equation and/or in volatility process. The purpose of this article is try to provide a unified way to understand the effect of these four factors on modelling the monthly time-series of ACDC level growth rate and find the most adequate and parsimonious model. In a Bayesian approach, we estimate a few extensions of the basic stochastic volatility model using the Markov Chain Monte Carlo (MCMC) method and compare these models using Deviance Information Criterion(DIC). Our study shows that the leverage effect is present also the SV models with independent jumps in observation equation and volatility equation perform well.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"2007 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127301356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The root explants from in vivo sources failed to respond whereas those from in vitro grown plantlets regenerated protocorm-like bodies (PLBs). An optimum of 16.2 PLBs developed from root explants on medium supplemented with 30µM BAP and 15µM IAA. The resulting plantlets were successfully transferred to pots containing brick pieces, charcoal chunks and decaying litter (1∶1∶1) + a top layer of moss.

Uptake via food is most important in terrestrial organisms and it may also be important in the aquatic environment. Dietary uptake can include heavy metals adsorbed on particulates present on the surface of leaves etc, which have not been absorbed by the plant. As discussed below, depending on context; heavy metal can include elements lighter than carbon and can exclude some of the heaviest metals. Heavy metals occur naturally in the ecosystem with large variations in concentration. In modern times, anthropogenic sources of heavy metals, i.e. pollution, have been introduced to the ecosystem. Waste-derived fuels are especially prone to contain heavy metals so they should be a central concern in a consideration of their use.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132788328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, due to shortage of water, farmers' desire to use groundwater in order to grow rice in northern part of Iran has been increasing rapidly. The fact that rice is sensitive to water quality, caused concern about rice cultivation sustainability in the area, especially in drought years. This study was done to investigate the interpolation methods and the spatial variability of some important ground water quality factors including EC, SAR and Na of samples taken from 135 wells over the region at September of 2007. First, the accuracy of ordinary kriging (Ok) and inverse distance weighting (IDW) with 3 different powers (1, 2 and 3) in mapping the studied parameters were evaluated. Then the final map was presented. The result showed that spherical model gave the best result to simulate the vriograms. Although negligible differences were observed between the methods, Ok and IDW-1 performed better in comparison to the IDW-2 and IDW-3. The final map showed that EC in central part of the region, where the Sephidroud meets the Caspian Sea is dramatically high which will threaten the sustainability of rice cultivation in the area. The other factors were in suitable level.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"610 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134399585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
