Miljöstyrning i byggprocessen. En kartläggning av pågående miljöarbete och framtida förbättringar.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Prövning av ett praktiskt verktyg för att främja likabehandling i skolan

The purpose of this study was to examine the laws, govern documents and guiding principals that are available for schools and their work regarding the work against discrimination, insulting and other forms of harassments, and then to form a method for the schools to implement this work in practice.The work to counteract discrimination, insult treatment and other forms of harassments should be done both in a short term and a long term. In this paper there is a presentation of a project, a set of lessons that was created and carried out as a trial. The project aims for conscious making among children and students in school regarding norm, deviation, discrimination and power and the fact that equal treatment is hard to achieve. The basic purpose behind the project is to offer a tool to schools and teachers so that they can decrease the possible gap between the laws and the practice of these laws by creating awareness among students and other teachers. The long term work for achieving equal treatment should be done on a political level.

Biogas till kraftvärme på Wapnö : en projektanalys utifrån ett företagsekonomiskt perspektiv

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

Ny slamhantering vid Hedesunda reningsverk

Hedesunda reningsverk är beläget i södra delen av Gävle kommun och hanterar avloppsvatten från Hedesunda samhälle och ett fåtal närbelägna byar. Antalet anslutna personer är strax över 1500. Reningsverket byggdes på 1960-talet och byggdes om i slutet av 1990-talet. Vid ombyggnaden anlades torkbäddar för avvattning av det slam som produceras vid reningsverket. Inledningsvis fungerade dessa torkbäddar bra men sedan 2005 har slammet i bäddarna inte avvattnats i önskad omfattning. Syftet med detta examensarbete var att utreda hur slamavvattningen i Hedesunda ska se ut i framtiden.

Investeringsalternativ för gårdsbaserad bioanläggning vid SLU

A Biogas plant in SLU?s (Swedish University of Agricultural Sciences) management sustains to behave in con-nection with the new animal stables at Lövsta. There will primarily manure from stables that rot to biogas. The biogas plant will also have the capacity that rot others substrates that can arise in the farm operation. The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.This study has implemented multiple cases study of different investment scenarios.

The aim of the study is to examine which present conceptions of sexuality there are in treatment of substance abuse for men. The intention is to examine how staff members in these environments perceive clients? sex and sexuality as well as studying if and in that case how they work with sexuality in treatment. A qualitative method formed the methodological approach and semistructured interviews were carried out for the collection of data. Four staff members from two different treatment institutions for substance abuse were interviewed.

Fågelbär (Prunus avium L.) - överlevnad, höjdutveckling och skador i unga planteringar på småländska höglandet :

Plant survival, plant damage and height growth were studied in nine wild cherry (Prunus avium L.) plantations in southern Sweden established between 2000 and 2002. All stands were located to the county of Småland. The survey was conducted during May and June in 2007. During the survey the height, diameter and quality of the cherry trees were recorded. In one stand, red ? berried Elder (Sambucus racemosa L.) was a dominant species.

Biogasprocessen : Bestämning av verkningsgrad

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

Mentaliseringsbaserad behandling av patienter med borderline personlighetsstörning : Infallsvinklar från patientgrupp och behandlare

The aim of this paper was to illuminate the effect of mentalizationbased psychotherapy. The patients in the survey group were interviewed before and after treatment with regard to specific symptoms of borderline personality disorder and symptoms of other personality disorders with the semi structured interviews ZAN-BPD and SCID-II. Open interview questions that were worked up in a qualitative manner were as well put to the patients that had received the treatment program. A focus group interview with the staff working with the concept within the frame of the MBT-team of Psychiatry southwest in Stockholm was also carried out. The result shows on a group level between the pre and post measuring a reduction of specific borderline symptoms like impulsivity and cognitive symptoms.

Analys av planering inom byggproduktion. Hur kan förbättring ske med hjälp av slututvärdering och återkoppling?

Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :

The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings. A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils. The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season. The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.

Återinläggning av patienter 80 år och äldre på medicin- och kirurgklinik

ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method:  Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine.  Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.

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.

Design av utomhusträdgård i Dubai :

To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation. It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.

Sustainability reporting within the food industry : a case study of regional differences in the plant-based non-dairy industry

Sustainability Reporting has emerged and transformed over the past decades as a voluntary practice by companies across industries that desire to show proof of good conduct and environmental; social; and economic responsibility. As industrial food production is one of the largest contributors to contemporary environmental problems, it might be expected that reporting within the industry would be both well established and well understood. Unfortunately, it is neither. In light of the food industry?s considerable environmental impact and the growing popularity of plant-based food as a more sustainable alternative to dairy products, this paper assesses and briefly discusses the Sustainability Reporting of two companies in the plant-based food and beverage industry. The research was designed to compare the practices of Europe-based Alpro and US-based SoDelicious, and this study has two major purposes: to describe the reporting of the case companies and to subsequently compare their practices to the other as well as to global reporting standards. The empirical study in this paper was conducted through content analysis.
