Effects of biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before Usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.

Full Circle: upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

MKB för vägprojekt i Sverige: Svårigheter med att tolka och använda en MKB

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

Värdet av en Virtuell Relation : Aktivitet i förhållande till kontext ? Spotify ur ett praktikperspektiv

The increased interest in relationship marketing and the potential of the Internet as a platform for relationship building activities have given rise to new ways for companies to interact with their customers, such as services based on a freemium pricing model. Based on the premise that relationships are processes consisting of interactive moments of value-creating activities, value is considered subjective, relative and dependent on the context in which the activity takes place. Value is therefore variable given its context and cannot be pre-defined without nuances being lost. Despite the Internet's given role in societal development, our understanding of what contributes to customers' intentions to build relationships with online services is yet to mature.As the music industry is well established on the Internet, alongside the change in how music is consumed, it is thus appropriate to examine activities in accordance with a freemium based service that distributes music online, since it still lacks in academic understanding.This study aims to provide insights about virtual relations and how online services that provide cultural content should relate to there users as well as contributing to the ongoing academic discussion regarding value and how it is manifested by highlighting contextual impact on relational activities. For a rapprochement of relations to online services in cultural industries, this study assumed a practice perspective.

Undersökning av luftkvaliteten vid småskalig biobränsleförbränning i två kommuner med modellsystemet VEDAIR

An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced.According to the result, there are areas with poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 µg/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Rättsäkerhet i den psykiatriska tvångsvården : Lagstiftning och tillämpning

This study examines whether or not there are inherit flaws in Swedish legislation concerning psychiatric institutional care, or in the application of the act, which might lead to the failure of rule of law for the private citizen. Law (1991:1128) concerning psychiatric institutional care in certain instances (LPIC) aims to establish rules which will ensure rule of law for the mentally ill in case of psychiatric institutional care. Despite this, there are legal cases which indicate that these rules, and their implications, are not always considered at the psychiatric wards.The questions at issues which this study aims to answer are thus: Are there any deficiencies concerning rule of law in LPIC 2?3 §§, 4?6 §§, 7?10 §§,15?25 §§ and 32?33 §§ ? This section focuses on LPIC and its design. Whether or not the act adheres to rule of law is examined through a definition which has evolved through discussions of concept based in Peczeniks definition of rule of law.

MKB also wishes to develop the park area which is centrally situated in Örtagården. The purpose of this study was to make an analysis of the development of Örtagårdsparken from when it was planned and constructed up until the state it is in today.

Antibiotika : användning och resistensproblem i fem länder

Sedan sin introduktion på 1940-talet har antibiotika varit några av de viktigaste läkemedlen vi har, både inom human- och veterinärmedicin. De används för att behandla och förebygga bakteriella infektioner. Världen över har det också använts i tillväxtstimulerande syfte i varierande grad, och på sina håll fortfarande även idag. Då administreras det i subterapeutiska koncentrationer under en lång tid vilket medför stora resistensproblem i det långa loppet. Syftet med denna litteraturstudie var att se hur fem länders antibiotikaresistensläge ser ut idag och vad som påverkar det. Detta uppnåddes genom jämförelser av ländernas antibiotikaanvändning och resistensläge på gris, exemplifierat genom tre olika bakterier ? MRSA, ESBL-producerande Escherichia coli och erythromycinresistenta Enterococcus spp.. De länder som studerades var Sverige, Danmark, Nederländerna, USA och Kina. Skillnader som finns mellan länder är exempelvis huruvida antibiotika får användas i tillväxtstimulerande syfte, om antibiotika måste vara receptbelagt och om det används i profylaktiskt syfte.

Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?

Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the Usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.

Belting - en studie av hur en sångteknik beskrivs och används

Uppsatsens syfte var att utforska och definiera belting, den kontroversiella sångtekniken som kommit att bli allt mer vanlig och använd bland sångare, som ett resultat av ett ökat intresse och flöde av populärmusik i vårt samhälle. Syftet var också att studera hur denna teknik används av sångpedagoger i deras arbete. Denna kvalitativa undersökning är baserad på litteraturstudier inom röstfysiologi och röstens funktion, och specifika teorier angående belting. Den grundar sig även på intervjuer av sångpedagoger som använder belting i sitt vardagliga arbete, både som pedagoger och som sångare. Resultaten visar att belting kan ses som en röstfunktion eller som en utvidgning av det låga registret, eller som en blandning av båda.

Challenges and incentives for sustainable manure management in Russia

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

Den fysiska planeringens påverkan på människans rekreationsmiljöer : tillämpning av de åtta parkkaraktärerna inom balanseringsprincipen

The development of our time, is due to great progresses in technology and an enormous ex-plosion of knowledge, has lead to an increased effort of our attention as a result of a boundless torrent of information . Higher productivity and efficiency in our workplaces and homes crea-tes fewer opportunities for rest, leading to a community where stress has become a national disease. Recreation is an important part of our lives in order to be able to deal with stress and is now considered to be an essential resource when it comes to sustainable development. Green spaces are therefore today viewed to play a considerable roll for the national health. Nature has proven to have positive influence on man which leads to a decrease in blood pressure, an increase in power of concentration and lowered production of stress hormones.
