Study was conducted on the physico-chemical water properties of Zobe reservor Dutsinma, Katsina State Nigeria. 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.
对尼日利亚卡齐纳州Dutsinma Zobe油藏的物理化学水性质进行了研究。在2015年5月至2016年4月期间,分别从Makera、Badole、Garhi和Bagaggadi四个不同的采样站采集水样。电导率、pH值、溶解氧(DO)、温度、碱度、浊度、硬度、氯化物和硝酸盐的样品在早上7点到9点之间收集。结果显示,各水质参数的月平均值均有变化。特别是在雨季开始时,水的浑浊度过高,尽管有这种变化,但有些值在大多数热带淡水鱼类的可容忍范围内。但是,这些水除非经过强化处理,否则不能用于家庭使用。

The current paper emphasizes on the study of the water resources of Iraq. 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.
本文着重对伊拉克的水资源进行了研究。由于到达伊拉克与底格里斯河和幼发拉底河边界的水的数量和质量下降,伊拉克正面临着严重的水危机。幼发拉底河和底格里斯河为伊拉克提供了98%以上的各种用水需求。这些河流的退化已经成为一个严重的问题。对以往的研究进行了分析,并收集了现有的数据。大多数研究都得出了一个重要结论,伊拉克面临着严重的缺水问题。对人口规模进行了分析和预测,对现有农业利用和耕地扩大进行了研究。本文对农业、城市和工业三种用途的取水消耗进行了分析和介绍。此外,根据对人口规模和供水量的预期,对到2100年的未来人均份额作出了预期。对新厂的水力发电进行了研究,并提出了建议。此外,向阿拉伯湾排放的一些淡水代表着淡水的损失。建议通过在巴士拉市上游建造一座新水坝来分隔淡水和咸水,以避免这一损失。本文收录了部分收集到的数据。

Similitude theory adapted to archaeological system analysis provides insight into thought processes underlying agricultural field-system designs used by Andean societies. A basic equation governing the optimum rate of food production dependent upon land, water, labor and technology resources is derived and compared to Chimu, Tiwanaku and Inka field-system designs. 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. The presentation illustrates that agricultural field-system designs were based upon scientific/economic principles and provide a further dimension as to how Andean societies successfully sustained their agricultural development.

Land Use and Land Cover Change (LULCC) is a major driver of environmental problems like water pollution, decreased soil quality, and natural resource scarcity. 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.
土地利用和土地覆盖变化(LULCC)是水污染、土壤质量下降和自然资源稀缺等环境问题的主要驱动因素。为了更好地了解流域现状,测量LULCC是必要的。利用地理信息系统(GIS)、高分辨率图像和现场数据收集的时间序列LULCC制图是检查LULCC趋势的有效方法。尼泊尔巴克塔普尔的Mahadev Khola流域是居住在巴克塔普尔市的人们的主要饮用水来源,该城市主要由高海拔的森林和低海拔的农业用地和定居点组成。本研究的目的是观察Mahadev Khola流域的LULCC动态,以更好地了解由此可能产生的社会和环境问题。利用GIS方法创建并分析了时序土地利用图。对当地居民的调查以及对选定的主要利益相关者的访谈,有助于深入了解过去的土地使用情景如何影响lulcc,以及如何受到lulcc的影响。2005年至2014年间,土地利用的显著变化被量化。结果表明:森林面积减少6.25%,耕地面积减少14.28%,居民点增加156.25%;调查和访谈答复表明,这种变化在很大程度上是由于农业集约化以及化肥和农药使用的增加。农业投入的增加增加了河流和水污染以及长期土壤退化的可能性。城市扩张和发展导致污水和固体废物污染河流,增加了当地社区的健康风险。森林总面积虽有所增加,但物种组成已发生变化,以刺梨松为主。其结果是河流水量减少,土壤和水酸度增加。本研究的结果对于分析LULCC与流域之间的动态关系,以改善尼泊尔和南亚东喜马拉雅地区未来的管理工作具有及时和重要的意义。

A study was conducted to evaluate the effect of supplementing Taro (Bolosso-1), Enset corm and Sugarcane stock on feed intake, weight gain and net return of fattening local oxen. 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.
本试验旨在评价饲粮中添加芋头(Bolosso-1)、恩塞特玉米和甘蔗原料对育肥地牛采食量、增重和净收益的影响。选用16头5岁左右、平均体重249公斤的当地未阉割公牛作为恩塞特玉米和甘蔗。采用完全随机设计,4头公牛被分配到一个治疗组。结果表明:添加芋头处理的犊牛日总干物质采食量(8.26 kg/头)和营养物质采食量显著(P<0.05)高于未添加芋头处理的犊牛日鲜草采食量(5.33 kg/头)(P<0.05)。芋处理显著(P<0.05)提高了公牛的平均日增重(0.75 kg/头),降低了料重比(11.14)。每单位动物的瘦肉和肥肉的比例意味着酒店和餐馆生肉的总增加值超过20,080 Birr。这也表明,特定价值链参与者为该地区销售9500 Birr的活牛增加了100%以上的价值。芋基补剂和甘蔗基补剂分别获得最高和最低的净收益。结论:在芋头资源丰富、价格低廉的地区,建议以芋头作为能量补充品育肥公牛。销售生肉的市场行为者过度利用利润空间,属于生产者,需要系统的政府干预才能有效地分享利益。通过适当的饲养干预,博拉纳肉牛被认为可以优化牛肉价值链中参与者的经济收益。

The water quality of rivers is an issue of serious concern today. Rivers are heavily impacted due to their use for carrying off the industrial, municipal, agricultural and domestic effluents. Water samples were collected for the present study from the Ganga River at Kanpur, Allahabad and Varanasi sites, during the period 2011-2012. 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. All these species are very hardy, in respect of poor water quality, thus they (exotic species) have powerfully invaded in degraded systems worldwide.
河流的水质是当今人们严重关注的一个问题。河流因被用于运输工业、市政、农业和家庭污水而受到严重影响。本研究的水样是在2011-2012年期间从甘普尔、阿拉哈巴德和瓦拉纳西的恒河站点收集的。最低气温(17℃)记录在冬季。pH、TDS、EC、硫酸盐、磷酸盐、硝酸盐、BOD和COD值在阿拉哈巴德站点呈现最小值。氯化物和溶解氧在坎普尔地区最低,碱度和总硬度在瓦拉纳西地区最低。与瓦拉纳西和阿拉哈巴德地区相比,坎普尔地区的水质非常差。然而,恒河水域可以容纳一些宽容的鱼类,如外来的鲤鱼和尼罗河鱼,还有鲶鱼。所有这些物种都非常耐寒,在水质差的情况下,因此它们(外来物种)在世界范围内的退化系统中具有强大的入侵能力。

Fifty water samples including Surface water, Dug well, Hand pump and Bore well during pre-monsoon (May- June) and post-monsoon season (November) in parts of Mulugu-Venkatapur mandals, Warangal District to an extent of 453 Km2 and falls under Top sheet No. 56 N/15 and 56 N/16 of Survey of India were collected. The samples were analysed for major ion chemistry to study the groundwater characteristics and its suitability for drinking as well as irrigation purposes. The pH ranges from 6.7-8 indicating water is slighly acidic to alkaline in nature. TDS ranges from 201-3612 mg/l and 154-3457 mg/l during pre and post monsoon season. Total Hardness (TH) ranges from 100-1000 mg/l and 38.8-2148 mg/l; Chloride ranges from 7.81-1667 mg/l and 7.6-1089 mg/l; sulphate ranges from 2-1533 mg/l and 5.2-1200 mg/l during pre and post season respectively. Majority of the samples are suitable for domestic purposes due to low to medium hardness, however few samples described very hard and unsuitable for domestic, drinking and irrigation purposes. Various indices like Salinity Index, Sodium Absorption Ratio (SAR), Kelly’s Ratio (KR), Residual Sodium Carbonate (RSC), Soluble Sodium Percentage (SSP), Permeability Index (PI) and Water Quality Index (WQI) are used to classify groundwater and surface water for drinking as well as irrigation purposes.

Kivi Plainis located in the northeastern city of Kiviin Ardabil province. Due to the large number of villages in the desert and its people engaged in agriculture and animal husbandry, Study of ground water to determination of the optimal location of wells is important. In this regard, geoelectric technique was used for studies of groundwater quality and quantity of Kivi plain. In this research, the resolution of the subsurface layers, detection of saturated zone, determination of basement, detection of the general direction of groundwater and changes of resistivity in sounding points and profiles have been studied. The number of 196 vertical electrical sounding on nine profiles and the number of 9 sounding in variety points and in vicinity of exploratory wells by schlumberger array in the study area have been taken. "IPI2win" software is used for the interpretation of vertical electrical sounding curves and one-dimensional modeling. By “Res2dinv”, twodimensional modeling and preparation of resistivity section have been taken. According to the results of the interpretation of the data in the study area, sediments inparts of the Middle East and Northern have developed, and from the surface to the depth of alluvium and marl deposits were included. More aquifer layers in marly sand deposits, silt and sand, crushed limestone and salty zones were observed. Basement is included most of marl (with the layers of sandstone and conglomerate), limestone and silt. According to the basement, the topography slope of the area and isopiezecurves, groundwater movement is toward the northeast.

If adequate measures are not taken to protect the water bodies in Ghana, the rivers will dry up and those left will be highly polluted and the country will have to import drinking water from the neighbouring countries and from abroad for human consumption. Also, lots of lives and property would be lost through flooding in most cities in every rainy season if certain habits like building on water ways and dumping of rubbish into drains are not discouraged.
如果不采取适当措施保护加纳的水体,河流将干涸,剩下的河流将受到严重污染,该国将不得不从邻国和国外进口饮用水供人类消费。此外,如果不鼓励在水道上建造房屋和向排水沟倾倒垃圾等习惯,在每个雨季,大多数城市都会因洪水而失去许多生命和财产。

Modelling Changes in the Carbon Chemistry of the Aquatic Media during Photosynthesis 光合作用过程中水生介质碳化学的模拟变化
Pub Date : 2016-06-30 DOI: 10.4172/2157-7587.1000250

Mathematical modeling of systems requires a considerable knowledge about the subsystems, and the various rate processes and transfer coefficients that control the system. 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.
系统的数学建模需要对子系统,以及控制系统的各种速率过程和传递系数有相当多的了解。其中一个系统涉及光合作用期间水生介质碳化学的变化,因为无机碳是水生介质中潜在的限制因素。我们采用水螅为主要光合生物的水缸和水塘两种人工系统,研究了水螅的碳化学变化和吸收的碳种类。该研究表明,二氧化碳是主要的分子物种,在它被吸收和缺乏的情况下;游离二氧化碳最初是由碳酸氢盐离子的解离而不是直接使用释放出来的。由于细胞内外的pH梯度,进入速率不能仅通过扩散直接计算,因此碳浓缩机制和水通道蛋白被认为参与了这一过程。这项研究给出了一幅清晰的图像,显示了自由形式的二氧化碳的数量,以及碳酸氢盐离子释放并用于光合作用的二氧化碳的数量,并且可以完美地计算出来。
