Water samples were collected from four different sample stations i.e., Makera, Badole, Garhi and Bagaggadi respectively, for the period of one year (May 2015 to April 2016). Samples for Conductivity, pH, Dissolved Oxygen (DO), Temperature, Alkalinity, Turbidity, Hardness, Chloride, and Nitrate were collected during the morning hours, between 7:00 am to 9:00 am. The result showed variations in the monthly mean values of all the water quality parameters tested. The water is too turbid most especially during the beginning of raining season, despite this variation some of the values were within the tolerable range of the majority of tropical fresh water fish species. But the water cannot be used for domestic use unless it undergoes intensive treatment.","PeriodicalId":17605,"journal":{"name":"Journal of Waste Water Treatment and Analysis","volume":"62 1 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91073391","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}

Iraq is facing a dire water crisis due to the decrease in the quantities and degradation in the qualities of the water reaching its borders with the two rivers Tigris and Euphrates. The Euphrates and Tigris rivers provide more than 98% of Iraq’s water demands for the various purposes. Degradation of these rivers has become a serious problem. Analysis of the previous studies is made and the available data are collected. Most of the studies reached an important conclusion, Iraq face serious water shortage problem. Analysis and Expectation of the population size, study of the existing agricultural use and expansion of the cultivated land are presented. The consumption of water withdrawals for the three purposes Agricultural, municipal, and industrial use are analyzed and presented in the paper. In addition, the Expectations of the share per capita are made for the Future until 2100, depending on the expectations of population size and amount of water supply. The water power is studied and suggestions for the new plant are made. Furthermore, some of the discharged fresh water to the Arabian Gulf represents a loss of fresh water. Suggestion to save this loss by constructing a new dam to separate between the fresh and salt water upstream Basra city is suggested. Some of the collected data is included in the paper.","PeriodicalId":17605,"journal":{"name":"Journal of Waste Water Treatment and Analysis","volume":"60 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91020860","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}

Actual designs are close to theoretical optimum designs demonstrating advanced engineering used in decision making underlying field-system designs. Further examples demonstrate how Andean societies managed land, water, labor and technology to provide economic advantage for their populations.

Measuring LULCC is necessary to better understand the present condition of watersheds. Time series LULCC mapping using Geographic Information Systems (GIS), high-resolution imagery, and field data collection are effective methods for examining LULCC trends. The Mahadev Khola watershed in Bhaktapur, Nepal, acts as a primary source of drinking water for people living within the Bhaktapur municipalitywhich is dominated by forest at higher elevations and agricultural lands and settlements at lower elevations. The purpose of this study was to observe LULCC dynamics within the Mahadev Khola watershed to better understand the social and environmental problems that can arise in consequence. Time series land use maps were created and analyzed using GIS methods. Responses from a survey of local people, as well as interviews from selected key stakeholders, contribute insight into how past scenarios of land use have influenced-and have been influenced by-LULCC. Significant changes in land use were quantified between 2005 and 2014. Results suggest that in this period, total forest area decreased by 6.25%, cultivation area decreased by 14.28% and settlements increased by 156.25%. Survey and interview responses suggest that much of this change is due to agricultural intensification and an increase in chemical fertilizer and pesticide use. Increased agricultural inputs have increased the potential for river and water pollution and long term soil degradation. Urban expansion and development have led to the contamination of rivers with sewage and solid waste, which has increased health risks for local communities. Although total forest area has increased, the species composition has changed-now primarily dominated by Pinus roxburghii. The result of this is a decrease in river water discharge and increase in soil and water acidity. The results of this study are timely and important for analyzing the dynamics between LULCC and watersheds in order to improve future management efforts in Nepal and the Eastern Himalayan region of South Asia.","PeriodicalId":17605,"journal":{"name":"Journal of Waste Water Treatment and Analysis","volume":"140 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77779911","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}

Sixteen local un-castrated oxen of about 5 years’ age and average weight of 249 kg were used as Enset corm and Sugarcane. A completely randomized design was used and 4 bulls were allotted to a treatment. The result showed that bulls supplemented with Taro treatment had significantly (P<0.05) higher daily intake of a total dry matter (8.26 kg/bull) and nutrients while the daily intake of fresh grass (5.33 kg/bull) on no supplemented treatment had significantly higher (p<0.05). Bulls supplemented with Taro treatment had significantly (P<0.05) higher average daily weight gain (0.75 kg/bull) and lower feed to gain ratio (11.14). The extent of lean and fat meat per unit of animal implies that the amounts of total value added inform of raw meat in hotels and restaurants exceed 20,080 Birr. This also indicates that the specific value chain actors added more than 100% value for the live cattle that marketed 9500 Birr in the district. The highest and lowest net return was obtained from bulls fed Taro based supplement and sugarcane based supplement, respectively. It was concluded that fattening bulls by using Taro as energy supplement is recommended for the areas where Taro is available and cheap. Market actors that sell raw meat overexploit profit margin belong to producers that need systematic government intervention for efficient benefit share. Introduction Borana beef cattle with appropriate feeding intervention is believed to optimize the economics gains of actors in beef value chain.","PeriodicalId":17605,"journal":{"name":"Journal of Waste Water Treatment and Analysis","volume":"29 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84043170","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 minimum temperature (17°C) was recorded in winter season. The pH, TDS, EC, sulphate, phosphate, nitrate, BOD and COD values exhibited their minimum at Allahabad site. The chloride and dissolved oxygen were recorded minimum at Kanpur site while alkalinity and total hardness had their lowest values at Varanasi site. The water quality of the Kanpur site was very poor compared to Varanasi and Allahabad sites. However, the Ganga river waters could host some tolerant fish species such as the exotic Cyprinus carpio and Oreochromis niloticus and also catfishes.

One such system involves changes in the carbon chemistry of the aquatic media during photosynthesis because inorganic carbon is a potentially limiting factor in the aquatic media. We used two artificial systems: an aquarium and a pond system with Hydrilla as the major photosynthetic organism to study the changes in the carbon chemistry and the carbon species taken up. The study depicts that carbon dioxide is the major molecular species taken up and in its absence; free carbon dioxide is released initially from the dissociation of bicarbonate ions rather than its direct use. The rate of entry cannot be accounted directly by diffusion alone because of the pH gradients in and out of the cell, and therefore carbon concentrating mechanisms and aquaporins  are thought to be involved in the process. The study gives a clear picture of the amount of carbon dioxide available in the free form and the amount released from bicarbonate ions and used in photosynthesis, and can be accounted perfectly.","PeriodicalId":17605,"journal":{"name":"Journal of Waste Water Treatment and Analysis","volume":"34 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78555252","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}
