The selection of suitable landfill locations for municipal solid waste has become a top priority, especially in developed countries as a result of rapid population growth, unplanned urbanisation, increasing waste production and the limited area available. However, determining the location of landfill sites is a complex decision-making problem for municipalities and depends on social, environmental, technical and economic factors and regulations. In this study, we combined a geographic information system (GIS), multi-criteria decision-analysis techniques and fuzzy logic to determine the best location for landfill sites in Adana, Turkey, in four steps. Firstly, the threshold values and the coefficient weights of 15 criteria, grouped into environmental and socio-economic factors, were determined by a literature review and expert opinion to select suitable landfill locations. Secondly, selection criteria were standardised using fuzzy logic. Thirdly, we assessed the criteria weights based on their effectiveness on the selection of potential landfill sites using the Simos method. According to the weight coefficients, environmental factors are more important than socio-economic factors. Final maps for each criterion were calculated and overlaid by a GIS. As a result, the final suitability results were divided into four discrete categories: very high, high, moderate and low suitability areas, representing 1%, 76%, 17% and 6% of the location options, respectively. Finally, four different alternative areas were identified as being very highly suitable for landfill locations, which were evaluated in detail using a strengths, weaknesses, opportunities and threats analysis. Three key aspects affect the final decision of a landfill site, in decreasing order of importance: environmental protection, minimising the negative impact on urban life quality and economic issues. Consequently, these results can guide decision-makers (ministries, municipalities, planners, etc.) during the selection of suitable landfill sites in both national and international studies.

AbstractThe paper presents environmental conditions for the selected location of a landfill site on the area of Stary Sącz designated for deposing neutral waste from the installation for secondary segregation of waste. Based on the productivity of the selected municipal waste parameters of accumulation indicators were detennined strictly correlated with the amount of waste predicted for disposal. Components of the facility were selected including the requirements of the resolution as of 30th April 2013 on landfill sites (Journal of Laws 2013 item 523) for application of solutions for protection of water, soil and atmospheric air environment in its surroundings against the negative impact of waste. The paper also refers to the final stage related to closing of a landfill with the assumed plan of its reclamation. The article was summed up with conclusions indicating the limited possibility of location of such a facility on the selected area on account of its location close to Poprad River and on the area of the Main Reservoir of Underground Water. The objective of the paper was to make an attempt to choose components of the installation for neutralization of waste in Stary Sącz taking into account the local environmental conditions.

Significant increase in municipal solid waste in Nepal has led to build up of few landfill sites in urban areas. Among several problems existing in the landfill sites, groundwater and soil contamination are the major problems. The major causes of contamination are generation of leachate, improper design and selection of materials in the landfill sites. Therefore, understanding on physical and chemical behavior of the leachate with the fill material, and the landfill site design parameters is required to solve the problem. Three landfill sites (Gokarna, Sisdol and Pokhara) were studied as case studied to identify leakage problems in view of controlling leachate migration. Hydraulic conductivity, particle size distribution and shape of basement material were studied. Gokarna Landfill Site did not have proper clay lining or other technology that prevents groundwater contamination. The Sisdol and the Pokhara landfill sites were improved sites but were devoid of clay lining. To control leachate migration, proper basement and other design is required. The slope of the basement clay liner should be adjusted properly according to the hydraulic conductivity of the clay to prevent leachate movement downward. Similarly, selection of shape and size of drainage material is important for aeration, and to prevent from leachate clogging and puncturing the basal clay or geo-membrane. The case studies suggested need of some improvements for basal design of landfill sites for future. Besides the basement design, design of leachate suction well and vegetative technology for leachate treatment are necessary. A basement design is proposed that will be economic and suitable for developing countries. This paper discusses about some drawbacks in technical practices in some landfill sites in Nepal and suggests possible methods that can be applied in constructing landfill sites for reducing contamination.   doi: 10.3126/bdg.v11i0.1542 Bulletin of the Department of Geology, Tribhuvan University, Kathmandu, Nepal, Vol. 11, 2008, pp. 51-60

Editor's Note: Guidelines for Selecting Books to Review Occasionally, we receive questions regarding the selection of books reviewed in the Journal of Economic Literature. A statement of our guidelines for book selection might be useful, therefore. The general purpose of our book reviews is to help keep members of the American Economic Association informed of significant English-language publications in economics research. Annotations are published of all books received. However, we receive many more books than we are able to review so choices must be made in selecting books for review. We try to identify for review scholarly, well-researched books that embody serious and original research on a particular topic. We do not review textbooks. Other things equal, we avoid volumes of collected papers such as festschriften and conference volumes. Often such volumes pose difficult problems for the reviewer who may find himself having to describe and evaluate many different contributions. Among such volumes, we prefer those on a single, well-defined theme that a typical reviewer may develop in his review. A volume that collects together papers from a wide assortment of different topics is not preferred to one devoted exclusively to one topic. We avoid volumes that collect previously published papers unless there is some material value added from bringing the papers together. Also, we refrain from reviewing second or revised editions unless the revisions of the original edition are really substantial. Our policy is not to accept offers to review (and unsolicited reviews of) particular books. We have examined the consequences of an alternative policy and have determined that we lack the resources to deal appropriately with unsolicited reviews. Coauthorship of reviews is not forbidden but discouraged and we ask our invited reviewers to discuss with us first any changes in the authorship or assigned length of a review.

Abstract OBJECTIVE: Appropriate clip selection frequently becomes a matter of trial and error because of inadequate dissection of the pathway for each clip blade. To facilitate selection of the proper clip size, a series of dissectors have been designed that mimic the exact caliber of each category of Sugita clips. METHODS: Three lines of sizer-dissectors reflecting the wire size of the most commonly used Sugita clips were developed by attaching a single aneurysm clip blade to a rounded microdissector handle. Each sizer-dissector is scaled in millimeters and is available in straight and angled configurations. Once dissection is presumed to be complete, the device is passed through the pathway of the intended aneurysm clip blades, and the clip with the appropriate caliber and length for permanent occlusion is selected. RESULTS: During dissection and clip ligation of 83 aneurysms, the sizer-dissector was used to select the blade length in 16 lesions and the blade caliber in 5 lesions. There were no complications associated with deployment of the device. CONCLUSION: By use of the sizer-dissector before attempting clip placement, clip selection is facilitated, safety is enhanced, and clip wastage is reduced.

This study assessed the groundwater quality around two municipal solid waste landfill sites, in the city of Bloemfontein, Free State Province, South Africa. The two landfill sites are located in two contrasting geological terrains, with both lacking some basic facilities found in a well-designed landfill. A total of eight groundwater samples were collected from pollution monitoring boreholes near the two landfill sites, with five samples representing the northern landfill site and three samples representing the southern landfill site. The samples were collected in the autumn and winter seasons to assess any possible seasonal variations. They were analysed for physicochemical (pH, electrical conductivity (EC), total dissolve solids (TDS), chemical oxygen demand (COD) and total organic carbon (TOC)) and microbiological parameters (Escherichia coli, total coliform). The results of the analysis showed that the waters from both landfills were generally dominated by Ca, Mg, SO4, and HCO3 ions. Some of the major anions and cations in the water samples were above the South African National Standard (SANS241:2015) and World Health Organisation (WHO) permissible limits for drinking water. Majority of the boreholes had total dissolved solids and electrical conductivity values exceeding the SANS 241:2015 and WHO permissible limits. Piper trilinear plots for the two landfill sites showed that Ca(Mg)HCO3 water type predominates, but Ca(Mg)SO4 and Ca(Mg)Cl were also found. These water types were further confirmed with expanded Durov diagrams, indicating that that the boreholes represented a water type that is seldom found which is undergoing ion exchange, typical of sulphate contamination. From the SAR diagrams, boreholes in the northern landfill site had a high salinity hazard with only one borehole in the southern landfill site having a high salinity hazard. The geology was found to play a significant role in the distribution of contaminants into the groundwater systems in the study area. The study concluded that the northern landfill site had a poorer water quality in comparison to the southern landfill site based on the analysed physicochemical parameters. However, the southern landfill site showed significant microbial contamination, due to the elevated amount of E. coli and total coliform concentrations. The high permeability of the weathered dolerites in the northern landfill site might have enabled the percolation of contaminants into the groundwater resulting in the poorer water quality.
