Effekten av kvävegödsling på gasproduktionen vintertid i boreala sjöar
To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.
Mjölksammansättning hos djur som helt eller delvis fastar under digivningsperioden
This literature study assembles current knowledge about CODD (Contagious Ovine Digital Dermatitis). The aetiology of this disease is not completely known and to obtain a manageable overview, this study aims to summarize the knowledge from published studies and shed light on the subject. Search for literature on the subject has been made in the Web of Knowledge, PubMed and Google Scholar, and has been compiled in this paper. Footrot and ovine interdigital dermatitis are differential diagnosis of CODD and they possibly have a common role in the emergence of CODD. Several studies have drawn parallels to bovine digital dermatitis.
Hantering av extensivt hållna nötkreatur i mindre besättningar
Extensive cattle management was reintroduced in Sweden during the 1950´s and 60´s. Usually this term refers to suckler cows for meat production that is kept outdoors all year around. Suckler cow farms tend to become fewer but bigger over time. Still however most of the farms with beef cows are small. Extensive animal husbandry can lead to animals becoming shy which leads to difficulties when they are handled due to veterinary treatments, marking, transport etc.
I vatten eller jord? : Nytolkning av depåfyndet från Eskelhem
In 1886 Hans Hildebrand received a Bronze Age hoard found in a field that belonged to Eskelhem´s rectory. A record was made where Hildebrand presented and documented the artifacts. The following year Oscar Montelius reviewed the artifacts, which he described as horse gears. He compared the horse gears with similar artifacts found in Europe that roughly had the same dating in order to trace the origin of the hoard. Montelius conclusion was that the hoard was created on Gotland around 500 BC.
Kartläggning av allmänhetens attityd till hörselnedsättning och självskattad kunskap om hörsel ? en enkätundersökning
Objective: 1.4 million people in Sweden state that they are having problems with hearing and the majority havehad no contact with the hearing rehabilitation services. To have a hearing loss seems to be associated withseveral negative attributes. This could be due to bad attitude and insufficient knowledge on hearing loss intoday?s society.Purpose: The purpose with this study was to map the adult populations attitude towards hearing loss and selfratedknowledge of hearing with a survey.Methods: A web survey was made for this study. An official link to the survey was shared from two Facebookaccounts to a total of 997 contacts and a total of 247 responses were collected.Results: The majority of the respondents have estimated their general knowledge of hearing to fairly extensivefollowed by very small.
Metanpotential för alger och bioslam blandat med pappersfiber
In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.
Mobilt internet för skogsbruket med CDMA2000 i450 MHz - bandet :
Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.
Omstruktureringars betydelse för organisatoriska lärprocesser : Ett kunskapsperspektiv på att dela en verksamhet och köpa verksamhetsnära it-tjäsnter
The thesis aims to understand how learning processes are affected when an organization split into two separate organizations. The study is designed as a single case, covering a new government agency?s takeover of a core activity from another agency and the use of a purchase-provider split between the agencies, providing the new agency with IT-services. The findings revealed a difference in productive system and knowledge types between core- and IT-activities. The core activity was found to be dominated by explicit knowledge while the IT-activity seemed to be dominated by a mix of explicit and tacit knowledge.
Finska dialekter i Sverige : En kvantitativ undersökning om sverigefinska skolans elevers syn på finska dialekter och tvåspråkighet
The purpose of this study was to investigate the view of Finnish dialects and identity of first, second and third generation of Sweden Finns students in 7th, 8th and 9th graders, in two Sweden Finn schools. The questions at issue for the essay were: How do Swedes of Finnish extraction think of the Finnish dialects? Is there a correlation between identifying as Finnish and knowledge and usage of the Finnish dialects, as opposed to Finns living in Finland? To which extent do the Finnish students have knowledge regarding the Finnish dialects? To answer the questions a quantitative method was used and a questionnaire was answered by over 100 students. The results of the study showed that the Finnish dialects did not exert any influence on the students? life nor their sense of identity.
Det lärande samarbetet ? mellan Angereds kulturskolor och grundskolor
This master is a study of the co-operation between "Angered?s culture schools" and compulsory schools. In many reports of today one can see that there is a lack of co-operation between compulsory school and other cultural institutions. This master aims to study a ?good example? to see what makes it successful in the terms of organizational conditions, profession, authority and legitimacy as well as knowledge creation.
Kunskapen, professionen och makten ? En kvalitativ studie om socionomens villkor och förutsättningar
My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

Information and inspiration were obtained by examining the company?s currently developed fixtures.After gathering the necessary information the process of developing three different fixture concepts started.
Anteckningar från en skyskrapa : En studie av Fjodor Dostojevskijs Anteckningar från ett källarhål och Bret Easton Ellis American Psycho
This survey aims to investigate and analyze how six teachers on a high school in Stockholm reflect on pedagogical aspects of problem based learning( PBL). The survey focuses on ana-lyzing how the teachers relate to the benefits and problems of PBL and how they reflect on the students development. The survey was conducted on a high school and the method used for the study was interviews, each taking 30-45 minutes. The outcome of the survey indicates that the teachers sees problem based learning as an alternative to what they define as tradi-tional education regarding its epistemology. They indicate that PBL allows the students to define their own questions, to be carriers of knowledge and to evolve analytic skills in relation to the basegroup.
Den allvarsamma leken : Om källan till mening i arbetet
Based on 30 years of work experience in TV and film production, I have made a phenomenological analysis of my perception of meaning in work - how it arises and how it is undermined. The story starts in my experience of early professional film making in the 1980's and describes how a change to work in TV production required the development of a new professional identity. The text also illustrates how as a female director I have managed my role in a male dominated and structured work environment. Being defined as an exception from the male norm has pushed me towards femininist reflection and the need to redefine my own work role - the generally accepted view having felt uncomfortable. An analysis of structural change in TV and film production shows how market pressures and ways of thought have increasingly invaded cultural endeavour. Professional spheres of influence are weakened, while developments in the media are characterised by a commercialism which encroaches more and more upon artistic, spiritual and moral values. This attitude, where quality is in retreat, has transformedprogramme makers from creative originators into becoming suppliers of raw material in a factory- like process geared to produce great volume at low cost.The aim of this essay is to show how changes in society and in TV and film making have affected my perception of my work.
En skola för alla? : en essä om hur vi förhåller oss gentemot barn som saknar de förutsättningar som den svenska skolan förväntar sig
In my essay the dilemmas originate from what I have experienced. I have observed myself and some of my colleagues, how we meet children who are lacking the qualifications which school and most pedagogues expect them to have. Focus, in my written experiences, is on children who live in poverty, but how we meet and act toward them is often quite the same independent of what qualifications they are lacking. With the support from literature and theories I reflect and analyse the dilemmas. Through essaywriting I investigate my practical knowledge and I examine how we as pedagogues handle the complex situations encounter when in school and how it is possible to understand why we act the way we do.I think that the knowledge which essaywriting gives me will strengthen me as a person and in my work as a teacher for after-school-center.
