Uppfödning av gyltor till hållbara suggor

Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.

Faktorer som påverkar kapitalstrukturen i nordiska fastighetsbolag

The bachelor's thesis is to examine the explanatory factors affecting the choice of capital structure in real estate companies. The analysis is based on data collected from the main financial reporting from 2007; all listed real estate companies listed on Swedish, Norwegian, Danish and Finnish stock market. Based on previous research and theories, we have defined five independent variables that are linked to the debt ratio, which are: profitability, growth, firm size, cost of debt and operational risk. The statistical tests have resulted in that we can say with certainty that profitable firms tend to have a lower debt to equity ratio. We can also say with certainty that property companies with high interest costs have a high level of indebtedness..

Det löser sig! : Förberedelsens betydelse för gymnasieelevers lärande vid kemilaborationer

Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in chemistry could be set, to become more meaningful for students. We introduced two preparation methods, and examined the outcome of students learning experiences and their acquisition of chemistry knowledge. This was examined both through surveys and observation.

Scrum ? en fallstudie från lokala företags perspektiv

Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything. The surveys were distributed to various local companies. After having received a lot of answers, I concluded that the clear priority was the most positive feature of scrum and the most negative was that it was difficult to get the rest of the organization to understand scrum, which creates problems. Both high school class and local companies believe in scrum?s future, even if they think scrum will be partially modified to adapt to the software-development in the future. According to the survey responses, the most important to get the projects to be successful both now and in the future is that everyone who work with scrum is right educated..

?Här leker vi inte pang pang Lucky Luke!? : Om pedagogers ambivalens till populärkultur i förskolan

The purpose of this paper is to examine teachers' approach to popular culture in preschool. The questions we want answered are: What approach do educators have to popular culture in preschool and what underlies that approach? Is there a high - and low culture in preschool? If educators bring popular culture into the preschool, how then is it used? Do children?s culture influence everyday life in preschool? We have employed qualitative methods to seek answers to our questions. We conducted seven interviews with educators from four different preschools. The starting point for our study was the socio-cultural perspective because we examined people's cultures and how the meeting between them unfolds. We concluded that educators have a very ambivalent attitude towards popular culture in preschool.

Vårdberoende, behov av omvårdnad och insatser för äldre med regelbunden vård och omsorg ? del av SNAC-Blekinge, Vårdsystemdelen

Background: The relationship between advanced age, presence of illness and impaired functioning is well known. A large proportion of the elderly population has an extensive need of care and service and therefore need help from municipal care. Aging is a transition in life and also affects the person's identity and self image, making the person particularly vulnerable and challenging everyday safety. It is therefore of importance to gain knowledge about which factors at individual and organizational level that support a person-centered nursing care for the elderly so that caring responsibilities and staffing of nursing personnel may be scheduled based on need. Aim: This study aimed at describing dependency and care needs of elderly persons living in ordinary housing, sheltered housing and nursing homes.

Motivation i praktiken - En fallstudie om vad som skapar ho g motivation hos erfarna IT-konsulter

The purpose of this study is to examine what creates motivation in the workplace of a small company with a high employee satisfaction index. The case study consists of qualitative interviews that help explain what the most important motivational factors are for the experienced IT consultants in a company that was founded by a circle of friends. The study concludes that the unique and equal pay model implicates an economic risk to the individual consultant but results in liberties, synergies and benefits. These appeal more than either self-employment or work at a larger IT consultancy that several consultants have backgrounds in. An expansion is ongoing since two years back, which threatened the culture but implicated opportunities for the individual consultants.

Preventiva trycksårsåtgärder. En litteraturstudie

Trycksår kan förekomma på alla typer av vårdavdelningar och tar lång tid att läka samt är en stor kostnad för samhället. Syftet med litteraturstudien var att undersöka åtgärder för trycksårsprevention. Metoden är baserad på en modifierad version av Forsberg & Wengströms modell för en systematisk litteraturstudie. Sökning i databaser PubMed och CINAHL utfördes och resultatet i litteraturstudien grundades på nio kvantitativa vetenskapliga artiklar. Författarna kunde identifiera olika preventionsåtgärder där framför allt evidensbaserade bedömningsinstrument som Modifierad Nortonskala och MNA-SF är viktiga att använda i trycksårsprevention, men även temperaturmätning, ?Continental anal plug? (CAP), god nutrition, aktivitet samt tryckreducerande underlag som fårskinn..

Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder

From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. Concerns have also been raised whether the sludge could interfere with the systems drainage capacity and thereby lead to high pore pressure in the dam, or if the measurement of seepage is disturbed, as the measuring is usually made via Thomson weirs, which could risk being blocked. The result of this investigation shows that the sludge is a result of the oxidation of iron by iron bacteria, and to the greater part consists of these oxides as well as the bacteria?s own structures. The iron oxidizing bacteria, FeOB, oxides ferrous iron to ferric as a part of their metabolism, and thereby create large quantities of iron(oxy)hydroxides.

Kylning och torkning av ett högtryckskompressorinlopp

Examensarbetet utfördes på University of Florida vid Department of Mechanical and AerospaceEngineering i deras Energy and Gas Dynamics Systems Laboratory. Laboratoriet forskar på enny gasturbincykel som producerar kraft, värme, kyla och vatten. Cykeln är kallad High PressureRegenerative Turbine Engine (HPRTE) och kombinerat med gasturbincykeln är ettabsorptionskylsystem (VARS). Kylsystemet drivs av spillvärme från avgaser som cirkuleras igasturbinen, den producerade kylan används för att kyla ned högtryckskompressorinloppet.Syftet med det här examensarbetet är att undersöka möjligheten till att kyla ned inloppet tillkompressorn till temperaturer långt under fryspunkten för vattnet i den fuktiga gasen. Om gasenskall kylas till nivåer under fryspunkten måste vattnet föras bort från gasen.

Störst, Bäst och Vackrast: En studie av varumärkessaliens påverkan på attityder och attributvärdering

The authors study the effects of brand salience on how consumers form brand attitudes and how consumers value the importance of various brand attributes. The study was conducted through two separate tests, the one focusing on the link between brand salience and brand attitudes and the other focusing on the link between brand salience and evaluations of attribute importance. Both tests measured brand salience as the ease with which brands are recalled by respondents who have been cued with a specific product category. The results show that brand salience has direct effects on both brand attitudes and the evaluation of attribute importance. As brands are recalled, high brand salience for a brand creates a more positive attitude towards that brand in the mind of the consumer.

Skördesystem i vall, skördens storlek ochfoderkvalitet

The choice of harvest date for leys is one of the most important factors affecting the size and quality of the harvest. An early harvest gives a high nutritive value while a late harvest gives larger quantity. Today?s aim to produce high nutritive leys gives early harvest dates both in primary growth and regrowth in northern part of Sweden. The consequence is a growth in the autumn, a "third harvest".The aim of this master thesis was to study the effects of different harvesting systems and their effect on size, feed quality, wintering and economy for conditions in the northern part of Sweden.
