Yet there is no international rating system for highways and roads design and construction comparable to the LEED rating system for buildings, or the Energy Star system for appliances. Sustainable highway infrastructure design requires a good balance between environment, cost and social aspects. Green design for roads should have a voluntary sustainability rating system for roadway design, construction, and maintenance. It should be applicable to all roadway projects including new, reconstructed and rehabilitated roadways. It awards credits point for sustainable choices and practices and can be used to assess roadway project sustainability. The rating system can be used to rank, score and compare different road projects for their overall performance toward being more sustainable than an average road project. The philosophy of the suggested rating systems will be based on different categories, each of which explain one sustainability attribute and covers different topics in subcategories. The aim of this work is to study the feasibility of using sustainable rating system for roadway project after considering the local environmental conditions, economy, and materials processing actions available. A questionnaire was designed which includes all the design categories, and was distributed to 150 participant including site engineers, design engineers, pavement contractors, material supplier contractors and road users (drivers and pedestrian). The impacts of roadway design and construction and suggested credits were obtained, these categories and credits are as important as the roadway design itself.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"20 1","pages":"99-106"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88309051","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}

Membrane is a dynamic lipoprotein structure and even the marginal changes of its physical parameters will be reflected on the structural and functional state of bilayer. For revealing the possible changes, the lipidprotein interactions in rat erythrocyte membranes after the in vivo chronic influence (6 days, 6 hours per day) of 200 kV/m electrostatic field were investigated. The biophysical parameters of erythrocyte ghosts were investigated by spectrofluorimetric method using the fluorescent probes 1-anilinonaftalene-8-sulfonate and pyrene. Oxidative modifications of membrane components were investigated also. The data obtained established that the field influence leads to the redistribution of membrane surface charge. It increases the immersion degree of the peripheral proteins in lipid bilayer and, in all probability, induces the conformational alterations of membrane integral proteins. These changes can be induced by the direct influence of field on the membranes and/or they can be a result of the field-generated changes in metabolic cascades. Our results emphasize the importance of membrane proteins in realization of the effect of electrostatic field.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"12 1","pages":"88-98"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85149627","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 this study, the municipal solid waste management and disposal methods in Abakaliki Metropolis, Ebonyi State, Nigeria is presented. The characteristics and composition of these wastes and the environmental issues associated with its management are also investigated. Structured questionnaires were used to obtain primary data from a random size of population in the areas that have the highest accumulation of heaps of solid wastes in the Government designated waste dumping sites and open spaces on the major streets within the metropolis. Environmental and health issues arising from the unsustainable management of the wastes were assessed from oral interviews and field observations in the study areas. The results indicates that the waste dump sites (designated and non-designated) on the major streets and several open spaces are left unattended for long periods such that the rubbish heaps; encroach on the roads thereby limiting the road users access, generate serious air pollution issues, constitute significant nuisance when blown over by winds, and distorts the aesthetic view of the metropolis. The results also show that the composition of the wastes in the metropolis is heterogeneous because it contains both biodegradable and non- biodegradable materials such as e-wastes, plastic, polythene materials, hospital wastes, and hair designers wastes amongst others. The study strongly recommend that Ebonyi State Environmental Protection Agency (EBSEPA) be made to sit up on their functions while Government should strongly consider introducing \"waste to energy\" as a way of curbing the menace of waste management and simultaneously solving the energy needs of the State.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"66 1","pages":"107-118"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76669416","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 unique properties of silver nanoparticles (AgNP) help in molecular diagnostics, several types of treatments and research purposes. The major methods used for silver nanoparticle synthesis are the physical and chemical methods. Silver nanoparticles can be produced by both physical and chemical methods. To overcome the problems faced by the huge expenses of physical and chemical methods and toxic substances absorbed onto them, biological method to synthesize AgNP is a suitable alternative. Silver nanoparticles have been used potentially to control larval stages of mosquitoes in the experimental conditions. Perhaps due to insertion of nanoparticles in cutical layer of larvae. Successful application of this may occur in near future to check mosquito borne diseases. The various modes of synthesis and application along with successive progress are discussed in this paper.

One such river considered in this study is the Patalganga, which is located about 60 km from Mumbai and is a significant source of water supply for Panvel, Alibaug and Rasayani. This paper aims to determine the polluting sources responsible for the poor water quality of the Patalganga River and to suggest a scientifically sound water quality management plan to improve the same. A total of 14 water samples from different point sources of pollution were collected and tested for physico-chemical parameters (pH, temperature, DO, BOD, COD, TSS, TDS, EC, PO4 3- , NO3-N and NH3-N), metals (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) and microbiological parameter using World Health Organization (WHO) and the Bureau of Indian Standards (BIS) standards. Based on, the water quality at most of the sampling stations was found to be unsuitable for drinking. Hierarchical cluster analysis (HCA) classified the 14 sampling stations into three clusters. The HCA identified a uniform source of parameters (physico-chemical and nutrients) for all the sampling stations, excluding two sampling stations (7 and 12) that exhibited anomalous concentrations. Furthermore, as per the WQI, the water quality status of Patalganga River fell under good category, except at the sampling station 7 and 12 where the water quality index were bad (49) and medium (51) category, respectively, and were totally unfit for drinking purpose. Water quality management plan specific to the individual sites has been delineated in the paper.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"13 1","pages":"71-87"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88263870","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}

Wells serve as the most affordable source of water in the rural areas but they are prone to surface runoffs and seepages from septic systems/pit latrines. This research was aimed at assessing the incidence of Entamoeba histolytica in well water used for human consumption and other domestic activities in Samaru-Zaria, Nigeria. Associated risk factors of well water contamination were studied. Membrane filtration technique was employed in filtering 70 well water samples (of 20 liters each) at the flow rate of 3liters/min through Millipore filter paper of nominal porosity of 0.45µm. Retained particulates were eluted in distilled water and concentrated by centrifugation. Wet mounts of the sediments were examined under 10x and 40x objectives of the light microscope. The incidence of Entamoeba histolytica was 38.6%. There was 72.9% level of parasitic contamination (including other parasites). Other medically important parasites were found in the well water samples, which included Enterobius vermicularis (2.9%), larvae of Strongyloides stercoralis (7.1%).
