The system is theoretically modelled using GMS (USEPA) and experimentally verified. Field experiments were carried out in M.P., India on Aonla plantation in arid areas (sandy soil with stone chips). Results indicate 40% more fruiting due to higher water use efficiency. Further experiments with nano organic pesticide extracted from neem (Azadiractin A, B and Limonoids) in emulsion form used in conjuction with EPIS system resulted into 50-90% reduction in four pests, Apical twig, gall maker, Leaf roller, Bark and shoot borer and, termites, for which data were collected.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"6 1","pages":"103-108"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90057899","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}

Therefore, it is desired that the conventional servomotors widely used in the industrial community are replaced with the synchronous reluctance motors (SynRMs) whose efficiency is high even though they have no magnets. The rotor position information is necessary to use SynRMs as servomotors, and several rotor position sensorless estimation methods have been proposed. These methods, however, have difficulties at low speed when the voltage signal necessary to estimate rotor position is very small. The authors have proposed a new position estimation method using high-frequency extended e.m.f. (EEMF) in which high-frequency voltage and current are calculated using a disturbance observer. Simulations have shown the new method to be very useful. In this paper, the feedback control of the high-frequency currents is proposed for becoming able to estimate the rotor position even though the high-frequency currents are very small when the checking of the new proposed method by experiments. And the experimental results show that it is possible to drive the motor at low speeds with the coordinate transformation used the position   estimated by the new proposed method.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"16 1","pages":"91-95"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81326737","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}

Some companies with concession land have already held contract of work and mining concession but yet to exploit the land. Most mining activities existed are traditionally conducted in the concession land. The inability of the local government to control the activities has led encroachment to protected forest and agricultural land. The consumption of mercury in gold processing could reach 34,000kg mercury day-1 with gold production approximately 22.5-45 kg day-1. The improper use of mercury has caused chemical, biological and physical soil degradation.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"11 1","pages":"79-83"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86976120","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 increase in the amount of leaching of Si from phosphor bronze was observed by the yellow sand atomizing. This is considered to be the promotion of leaching by the yellow sand atomizing. The amount of leaching of Cu from phosphor bronze was conversely reduced by the yellow sand atomizing. This is considered to be the leaching control by the yellow sand. In some cases the amount of leaching of Al and Si from aluminum casting without the yellow sand atomizing was more increased than that with the yellow sand atomizing. The leaching of Cu from aluminum casting was almost unaffected by the yellow sand atomizing.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"40 1","pages":"113-120"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86478128","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}
