Energy from municipal solid waste in Chennai, India : a feasibility study

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.

Critical Success Factors When Performing a Superior Supplier Evaluation ? a Benchmark Study at Sony Ericsson and Tetra Pak

Problem discussion: Long-term supplier relationships have become more common. Hence, supplier evaluation is a critical activity for many companies. However, making a relevant supplier evaluation is time consuming. Therefore, it is important to decide which of the suppliers to put an extra effort on. Should all suppliers be evaluated in the same way? Previous, focus has been on purchasing of direct material.

Historiska emissioner av bly och arsenik till luft från Åfors Glasbruk och deras konsekvenser för miljön.

Åfors glasswork was a company which started in 1876 and closed in 2012 due to the bad economical situation in the company. After its closure, the glasswork left behind contaminated soil with different concentrations of heavy metals such as, arsenic from arsenic trioxide, a chemical used to remove bubbles during the melting of glass, and lead oxide, a chemical used in the production of crystal glass. Crystal glass?s production occurred under 1921-1971, but emissions of lead into the air from Åfors glasswork continued until 2011, because of the artist Bertil Valliens? artglas was made in Åfors glasswork from 1970?s and onwards.The aim of this study was to estimate how much lead (Pb) and arsenic (As) that were released by Åfors Glasswork into the atmosphere during the operational period of the glasswork in comparison with how much of lead and arsenic were purchased for the company. Added to the assistance of the data from National Archives the variations in the activities of Åfors glasswork could be shown.

Outnyttjade resurser inom park- och naturvård

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Patotyptest av potatiscystnematoden :

There are two species of potato cyst nematode (PCN), the yellow, Globodera rostochiensis, and the white, Globodera pallida. Each of them can appear in different pathotypes. These are separated by testing the nematode ability to multiply on a number of potato cultivars with different resistance properties. The aim of this project was to examine the virulence of Swedish and foreign PCN populations and to compare two test methods. Biotests are today the only available tests used to study virulence.

Optimalt ekologiskt : att gestalta praktfulla parker som kan skötas på ett hållbart sätt

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

Energieffektiviserande åtgärderpå Robertsfors VA-nät : En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Minska tjänsteresor genom mätning - En fallstudie om att öka medvetenheten kring tjänsteresor med hjälp av verksamhetsmått

Background: In a world that are becoming more and more aware of the climate changes that occur as a consequence of the increasing emissions around the world companies? experience that the opinion blame the internal processors for this. Many companies feel forced to align their strategies to the environmental goals set by the community. Some of the emissions the companies? operations can be linked to business trips and it is therefore interesting to see how these can be reduced by using different performance measures.

Evaluation of indirect blood pressure measurement, plasma endothelin-1 and serum cortisol in clinically healthy horses

Equine metabolic syndrome (EMS) it?s a clinical condition that includes obesity, regional adiposity, insulin resistance (IR) and laminitis. A similar syndrome exists in human medi-cine, the metabolic syndrome (MS), were systemic hypertension also is a prominent fea-ture. The systemic hypertension seen in humans with MS is partly due to a vascular endo-thelial dysfunction with an enhanced endothelin-1 (ET-1) mediated vasoconstriction. There are indications that systemic hypertension might be a feature in EMS as well but if ET-1 is involved in the development of the systemic hypertension in horses is not known.

Den militära nyttan av kurskorrigerande tändrör

Sveriges ökade engagemang i internationella konflikter har förändrat under vilkaformer och i vilka miljöer som dagens militära operationer genomförs. Framföralltinnebär det att alla insatsförband inom Försvarsmakten ska kunna verka inom allakonfliktnivåer och i de flesta miljöer, även i urban terräng. Som en följd av dettauppkommer nya behov och krav på den indirekta bekämpningsförmågan i form avprecisionsbekämpning.Syftet med föreliggande arbete är att kartlägga om, och till vilken grad, ettkurskorrigerande tändrör bidrar till att öka den taktiska effektiviteten förstådd somverkanseffektivitet, kostnadseffektivitet, logistisk effektivitet samt minskad oönskadsidoverkan. Kartläggningen sker genom en komparativ litteraturstudie medkompletterande expertintervjuer.Med hjälp av kurskorrigerande tändrör som medger nära precisionsbekämpning kanen rad vinster erhållas. Exempel på sådana vinster är minskad spridning samt ökaddimensionering av verkan, minskad risk för oönskad sidoverkan, en lägre totalkostnad för ammunition samt minskat behov av transporter genom ökad effekt av detenskilda skottet..

Sexmånadersregelns förenlighet med EU-rätten

The purpose of this thesis was to analyse if the six month rule in chapter 3 § 9 part 1 in IL is compatible with EU law regarding the free movement of employees and in case of discrimination whether the rule can be justified. First of all the retroactive salary for an unlimited taxpayer and during the period of income earning a limited taxpayer who later became unlimited taxpayer will be analyzed in order to determine if they are considered to be in a comparable situation. An unlimited taxpayer is subject to taxation in Sweden for all of his incomes regardless their origin. However there is an exception according to six month rule, which implies that physical persons who stay abroad due to their minimum six months employment are in Sweden free from their incomes earned abroad if they are taxed in the country of employment. Tax exemption is applicable even if the payment from an employee working abroad is made retroactively.Article 18 EUFF states a general prohibition of discrimination on the grounds of nationality.
