Landfills – Territorial Issues Of Cities From North-East Region, Romania, Florin C. Mihai, Pavel Ichim

Florin C MIHAI

Landfilling prevails in waste management options in Romania like others new EU members, being contrary to the concept of waste hierarchy promoted in recent years by EC. Waste disposal is done usually in non-compliant landfills and Government established a program to close these sites. This paper aims to analyse the transition from traditional waste management systems to an integrated system at national, regional and local scale. Assessment of landfills location based on buffer analysis (using GIS techniques) is made according to the proximity of five critical factors (CF) such as: residential area, industry & commercial units, agricultural lands, rivers & …

Estimations Of Flood Waste From Rural Dumpsites Located On Floodplains From Neamţ, County, Romania, Florin C. Mihai

Florin C MIHAI

Waste dumping is a serious environmental threat to major rivers from extra- Carpathian Region of Neamţ county in the proximity of villages because the lack of waste collection services. In this context, floodplains are frequently susceptible to such bad practices, these areas being also exposed to stronger floods. The paper aims to calculate the potential waste taken from these areas in order to assess a quantitative impact of these bad practices.

Preliminary Summary Of Water Resource Investigations During 2012 At Timpanogos Cave National Monument, Utah, Lee J. Florea, Chelsie R. Dugan, Camille Mckinney

Lee J Florea, PhD, P.G.

This manuscript considers the hydrology and geochemistry of water resources within Timpanogos Cave National Monument in American Fork, Utah. In particular, data are presented for five cave pools within the Monument and the American Fork River that flows through the Monument. Two independent dye trace attempts in this study have not established a connection between the surface near the canyon rim at the south border of the Monument and the cave pools or the river. Ion chemistry of the pools reveals elevated sulfate concentrations. Analysis of sulfate and other reaction products suggests the possibility of combined carbonic and sulfuric acids …

Long-Term Environmental Problems And Strategic Intergenerational Transfers, Timo Goeschl, Daniel Heyen, Juan B. Moreno-Cruz

Juan B. Moreno-Cruz

The impacts of long-lived stock pollutants and the measures supposed to address them link current and future generations. Altruism towards successor generations is a prerequisite for resolving the resulting inter-generational equity issues. Preference asymmetry and imperfect altruism introduce strategic conflicts between generations. Here, a current generation decides on a combination of abatement and whether to provide an imperfect backstop. The future generation decides whether to use the backstop or not. We identify three outcomes: (1) Technology denial, in which the current generation deliberately rejects the imperfect backstop to avoid misuse by the future generation. (2) Under-abatement, in which the current …

Clarification Of Rubber Mill Wastewater By A Plant Based Biopolymer – Comparison With Common Inorganic Coagulants, Sumona Mukherjee

Sumona Mukherjee

Background In this study, the efficiency of Guar gum as a biopolymer has been compared with two other widely used inorganic coagulants, ferric chloride (FeCl3) and aluminum chloride (AlCl3), for the treatment of effluent collected from the rubber-washing tanks of a rubber concentrate factory. Settling velocity distribution curves were plotted to demonstrate the flocculating effect of FeCl3, AlCl3 and Guar gum. FeCl3 and AlCl3 displayed better turbidity removal than Guar gum at all settling velocities. Result FeCl3, AlCl3 and Guar gum removed 92.8%, 88.2% and 88.1% turbidity, respectively, of raw wastewater at a settling velocity of 0.1 cm min−1, respectively. …

Investigations Into The Potential For Hypogene Speleogenesis In The Cumberland Plateau Of Southeast Kentucky, U.S.A., Lee J. Florea

Lee J Florea, PhD, P.G.

This manuscript offers preliminary geochemical evidence that investigates the potential for hypogene speleogenesis in the Cumberland Plateau of southeastern Kentucky, U.S.A. The region was traditionally considered a classic example of epigenic karst, but new insights have uncovered tantalizing observations that suggest alternatives to simple carbonic acid speleogenesis. Such first-order observations have included natural petroleum seeps at the surface and in caves, occasional cave morphologies consistent with action of hypogene fluids, and prolific gypsum within cave passages. To this point, geochemical data from caves and springs verify carbonic acid as the primary dissolutional agent; however, these same analyses cannot rule out …

Spatial Analysis Of Dumpsites Volumes From Rural Territory Case Study: Neamt County, Romania, Florin C. Mihai, Andreea Lămășanu

Florin C MIHAI

Open dumps was the main option of the local communities in household waste management, this practice being banned after July 16, 2009. The paper examines the correlation between dumpsites volumes, population density and local geographical conditions in the context that in most rural administrative-territorial units of the county there were no facilities for waste collection. The geographical distribution of dumpsites volumes reflects the disparities between different areas of the county and on the other hand, it highlights the spaces exposed to pollution. Also, the comparative analysis between 2004 (pre-accession) and 2009 (post-accession) reflects a rudimentary waste management system in this …

Florin C MIHAI

The paper examines tourism as potential source of waste generation in urban and rural areas of Neamt county. An assessment method is proposed and the final result is mapping the process at local scale. In order to analyze the tourism impact on local waste management system, the waste generated by tourists (estimated values) is related to local household waste generation. This paper outlines the disparities within cities and communes and it also analyses the bad practices of tourists supported by field observations

Performance Assessment Method Of Urban Waste Management Systems From Neamț County, Romania, Florin C. Mihai

Florin C MIHAI

This paper proposes a performance assessment method (PAM) at urban scale, based on five specific waste indicators such as: population access to waste collection services (%), separate collection (%), reuse & recycle (%), landfilling (%) and amounts of waste uncollected (Qwu-%). Values of each indicator are correlated to an assessment table for three different years (2004, 2007, 2010) highlighting the disparities between urban localities of Neamt county. The paper also examines the changes and dysfunctions of urban waste management systems between preaccession vs post-accession period. PAM should be a necessary tool for environmental authorities or decision-makers for monitoring process of …

Semi-Automated Classification Of Gray Scale Aerial Photographs Using Geographic Object Based Image Analysis (Geobia) Technique, Ahmed Harb Rabia, Fabio Terribile

Ahmed Harb Rabia A.H. Rabia

Aerial photography is an important source of high resolution remotely sensed data. Before 1970, aerial photographs were the only remote sensing data source for land use and land cover classification. Using these old aerial photographs improve the final output of land use and land cover change detection. However, classic techniques of aerial photographs classification like manual interpretation or screen digitization require great experience, long processing time and vast effort. A new technique needs to be developed in order to reduce processing time and effort and to give better results. Geographic object based image analysis (GEOBIA) is a newly developed area …

Introducing A New Parametric Concept For Land Suitability Assessment, Ahmed Harb Rabia

Ahmed Harb Rabia A.H. Rabia

In an ecosystem, there is need to establish the quantity and quality of resources and their suitability for a certain range of land uses in order to assure its future productivity and sustainability of biodiversity. Parametric methods are widely used for land suitability evaluation. A new parametric concept “equation” of land suitability evaluation has been proposed to improve results of land suitability evaluation. Land suitability assessment for wheat production was conducted in order to compare results of the suggest method with classical parametric methods. Organic matter, CaCO3, pH, Slope, texture, drainage, depth, EC and altitude were recognized as factors affecting …

Landfills As Anthropogenic Landforms In Urban Environment From Neamţ County., Florin C. Mihai, Liviu Apostol, Adrian Ursu, Pavel Ichim

Florin C MIHAI

Landfills are the most common and easiest methods to dispose the municipal waste in Romania and still prevails in current waste management options. This type of critical infrastructure was designed to dispose urban waste generated over years or even decades and ultimately led to create new landforms in urban landscape. On the other hand, these sites are major sources of complex pollution unfulfilling EU regulations, being scheduled to be closed. This paper aims to analyze landfills as anthropogenic landforms by applying GIS techniques emphasizing them in a geographical context and not only in situ. The location of these sites usually …

A Spatial Approach To Energy Economics, Juan B. Moreno-Cruz, M Scott Taylor

Juan B. Moreno-Cruz

We develop a spatial model of energy exploitation where energy sources are differentiated by their geographic location and energy density. The spatial setting creates a scaling law that magnifies the importance of differences across energy sources. As a result, renewable sources twice as dense, provide eight times the supply; and all new non-renewable resource plays must first boom and then bust. For both renewable and non-renewable energy sources we link the size of exploitation zones and energy supplies to energy density, and provide empirical measures of key model attributes using data on solar, wind, biomass, and fossil fuel energy sources. …

Classification Of The Alterations Of Beaver Dams To Headwater Streams In Northeastern Connecticut, U.S.A., Denise Burchsted, Melinda D. Daniels

Denise Burchsted

Of the many types of barriers to water flow, beaver dams are among the smallest, typically lasting less than a decade and rarely exceeding 1.5 m in height. They are also among the most frequent and common obstructions in rivers, with a density often exceeding ten dams per km, a frequency of construction within a given network on a time scale of years, and a historic extent covering most of North America. Past quantification of the geomorphologic impact of beaver dams has primarily been limited to local impacts within individual impoundments and is of limited geographic scope. To assess the …

Challenges And Prospects Of Processes Utilising Carbonic Anhydrase For Co2 Separation, Patrycja Szeligiewicz, Wojciech M. Budzianowski

Wojciech Budzianowski

This article provides an analysis of processes for separation CO2 by using carbonic anhydrase enzyme with particular emphasis on reactive-membrane solutions. Three available processes are characterised. Main challenges and prospects are given. It is found that in view of numerous challenges practical applications of these processes will be difficult in near future. Further research is therefore needed for improving existing processes through finding methods for eliminating their main drawbacks such as short lifetime of carbonic anhydrase or low resistance of reactive membrane systems to impurities contained in flue gases from power plants.
