Climate change triggered by global warming is expected to have widespread consequences and subsequent usage and overloading of conventional energy resources. These effects will have major impacts on ecosystems, health, water resources and key economic sectors. Most of the vernacular building design considerations have a window and a small opening at ventilator level / beneath the ceiling at opposite wall to create natural ventilation to the building envelop through thermal buoyancy effect. Natural ventilation by thermal buoyancy in a building with a window and a small opening at ventilator level and periodic solar thermal model have been integrated to investigate the thermal behaviour of a non-air conditioned building. The Solar thermal model has been considered to analyse the indoor air temperature swings for heating and cooling periods with due considerations to the building components such as walls/roof, periodic solar radiation, isothermal mass, openings (window and door opening), ACHs and ambient air temperatures. The vernacular concept has been studied through solar thermal model to elaborate the influence openings on indoor air temperature swings and to consider its importance in designing of the non-air conditioned buildings for conservation of energy at micro level and to save a large amount of energy at settlement level as the over-all temperature in the room is a sensitive function of the size of the openings i.e. windows and ventilators / slits.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"30 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":"116059262","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 means of achieving this is by tapping the power available in vortices that are formed when a fluid flows over an obstruction placed in its path. The uniqueness of this concept is that energy can be tapped from fluids flowing at very low velocities. This has not been possible till date. The minimum fluid velocity required to harness energy from it has been 5 knots (approximately 2.572 m/s). Even at these speeds the process is very inefficient and not feasible. This necessitates the construction of dams, so that we can increase the flow velocity of fluid to levels at which power generation is productive. These dams cause severe strains on the environment and lead to displacement of the inhabitants of the area The concept proposed here, will generate the same amount of electricity as done by a dam, if laid across a 100m length of flowing water without any of the profound effects mentioned above.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"52 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":"116196119","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}

Every effort for sustainable development and environmental protection is in line with efforts made for improving public health. Accurate modeling methods in environmental studies indicate that there are few environmental disorders without public health consequences. One of the most important agents of environmental pollution & destruction is wars and conflicts. In local and regional wars, all parties involved in conflicts try to damage their enemy in order to put more pressure on them. But consequences of war and conflicts is not restricted to one aspect, time or period but extends even to next generations health, life and environment. In late Oct. 2008 a war occurred in the Middle East, and its news quickly spread around the world. War was started when Hamas did not accept cease-fire, and launched rockets toward Israeli cities on the other hand Israel's army also attack Gaza Strip. In Gaza-Israel 22 days war not only military positions but also civilians and environment were targeted and destroyed. During the war, hundreds of civilians were killed. The environment was also severely destroyed. Because of the specific characteristics of the Gaza Strip region- high-density population and highly urbanized- the recent violent military invasion put additional pressure on Gaza citizens. This status is not only harmful to Gaza citizens & environment but also Israeli people. During the attack infrastructures and buildings (including schools) were completely destroyed. Many of these buildings and infrastructures were connected to sewage networks, and since almost all the region's sewage flow into Mediterranean, spreading untreated sewerage into the Sea is an implication of high volume degradation, also flow of untreated sewage into ground water tables endangers citizens health residing in the region (through consumption of contaminated seafood). On the other hand, using white phosphorous also caused severe human injuries and environmental pollution. This paper is prepared using descriptive - analytical methods, with analyzing internet and library documents to investigate the adverse consequences of the conflict and war which occurred in regional level between Israel and Gaza but had impacts on the whole region's environment and citizens health.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"1 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":"130440082","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}

Thus, accurate estimation of flood discharge in every region can lead to more precise hydraulic structures with adequate capacity to avoid the above problems. Usually, the estimation of flood capacity in any station required sufficient data. However, the lake of sufficient and long-term hydrological data in many situations is a major threat to the start new projects. Thus, it is necessary to develop new methods for different circumstances and situations to estimate the required data for the target station. In this study artificial neural network has been applied to the reconstruction of annual discharge of hydrometric stations in Urmia Lake Basin and the results have been compared with those of normal ratio method to introduce the best technique for this study. It was shown that neural network provides the best approximation based on the root mean square of the estimated errors (RMSE), the percent of volume error (VE), and the correlation coefficient (R2).","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"20 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":"123030631","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}

In fact, the deserts are so beautiful the same as forest, oceans and grasslands with a lot of unique and interesting attractions. The greatness and calmness of the desert are presented the silence and peace which is not accessed in urban life for the human being. The sky and earth are boundless, horizon is endless and the night is infinite in the desert. You can watch bright and shiny starts mass and even milk way there. The dry earth reminds the blessings such as water and prosperity. The profound and long roots of the plants are the symbol of the resistance and endurance, and the green plants of the salt marsh state the love to the life. In our tensional and stressful world, desert lands are the spiritual shelter for the fatigued and exhausted soul of the people. This study is about taking advantage of the natural tourism attraction of the desert like sand and salt in order to cure the patients and to create calmness contemporary.

To test this observation, geometric morphometric analysis on a total of 976 A. fulica shells from several geographical locations in the Philippines was done. These were collected from the island of Bohol (Agapi, Ondol and Quinoguitan) and in the island of Mindanao - Davao City and Davao del Norte (Davao Riverside, Emily Homes, Las Arenas, New Corella, Nova Tierra and Panabo), Mindanao State University Main Campus, Mimbalut in Iligan City and Balangao, Zamboanga Sibugay. Images of the shells were captured, digitized and subjected to relative warp (RW), canonical variance (CVA) and linear regression analyses to determine whether populations in geographic isolation are phenotypically differentiated to serve as basis for the observation of geographical differentiation in A. fulica. Based on CVA, results showed differentiation of populations; however within population variability was also found to be high. This is in contrast with linear regression involving centroid shapes which revealed slight differentiation between populations. Based on RW analysis, results revealed shells of A. fulica have the following shapes - shells with elongated spire with narrow whorl and narrow aperture, elongated spire with narrow whorl and rounded aperture, short spire with wide whorl and rounded aperture, and short spire with wide whorl and narrow aperture. The findings in this study suggest that although there are notable morphological variations, it may not be substantial to conclude that speciation has taken place in this species.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"50 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":"116006544","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}
