Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration

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.

Hållbarhetscertifieringssystem och kommunalt hållbarhetsarbete :  

The municipalities of Sweden have a great responsibility when it comes to adapt the physical planning to a more sustainable development. The development of the society depends upon the growth of new communities and other public services, but to build new communities in a long-term sustainable manner you need good methods and guidance. This study presents four sustainability certification scheme intended to improve and adapt the planning, implementation and performance of new communities and infrastructure project to more sustainable methods based on economic, ecological and social sustainability. These systems are the latest versions of environmental classifications and similar rating schemes, but with a broader focus since they also include the social aspect of sustainability.This study aims to investigate what role sustainability certification schemes can play in local planning for sustainable development. The study compares the certification systems criteria to the tools and goals that the Swedish municipalities have been provided with, to lead efforts towards a more sustainable society.

Press på lokal demokrati : En kvantitativ innehållsanalys som undersöker huruvida hypoteserna i betänkandet av 1972 års pressutredning uppfylls när Östrans lokalredaktioner läggs ner i Emmaboda och Torsås.

This theisis aims to expand the understanding of how the termination of Östran local editorial staff is effecting the municipality politics and organisation orientated substance of the rivale newspaper Barometern when it becomes a monopoly news paper. I examine if the hypothesis in consideration of the press investigation of 1972 will occur through a quantitative analysis of selected articles in Barometern and Östran in 2010 and 2014. I examine if the information will be insufficient, if it will be a monopoly of opinion formation, if the investigative journalism will be suffering and if the group communication will be worse.With this analysis it becomes clear that the news paper Barometern cover less of the municipality politics and organisation orientated substance when it is a competive news paper. My analysis shows us that the information will not be insufficient, it will not be a monopoly of opinion formation, the investigative journalism will not be suffering and the group communication will be worse when Östrans local editorial staff is terminated. .

Säkerhet i Wireless Local Area Networks : En studie i säkerhetslösningar utförd på uppdrag av Saab Bofors Dynamics AB.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

The welfare of the laboratory mouse : comparison in development of mouse pups in three different individual ventilated cage (IVC) systems

Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

Porten till förståelse: svenska bibliotek och invandrare

The purpose of this paper was to investigate the special services for immigrants which are offered by Swedish libraries on their different levels regional, local and school as well as immigrants experiences of the library services and how these services and experiences conduct themselves to the development of the harmonic multicultural society. The methods used were interpreting reflexive interviews with immigrants and librarians. The guiding theory in this study was a three-phase model by Gillis Herlitz according to which a newcomer goes through three stages in an adaptation period. Phase 1 is a positive honeymoon phase, that later is replaced by phase 2, a critical disappointment period, which then ideally should be resolved in phase 3, where the individual reaches a balancing stage of cultural adaptation. The results of my observations indicate that the performances of the different libraries seem to operate in a way that corresponds to the different phases in this model.

Hygienisk kvalitet hos svensk älgfärs med avseende främst på förekomst av koagulaspositiva stafylokocker och Escherichia coli :

In this study the hygienic quality of minced moose meat was examined with regard to the prevalence of different bacteria. The methods used are described in NMKL, "Nordic Method Committee for Food". The results show that the levels of Escherichia coli and coagulase positive staphylococci in the meat are too high. The reason for this might be environmental factors, such as high temperature and humidity during the time when the carcasses are hanging and when the meat is cut up..

Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

NGO?s role in a public-private partnership : assessment of environmental educational efforts on short term

Business is changing and so are society?s expectations. Companies are expected to take responsibility for their trade and the context they are operating in, by looking at socially, economically and environmentally aspects. Many companies handle it by implementing corporate social responsibility (CSR) to their line of action. This is often handled by collaborating with other organisations, such as non-governmental organisations.

Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.
