Fysiska strukturer i Umeälvens gamla älvfåra och dess inverkan på laxsmoltens utvandringsframgång

The survival of hatchery reared smolts is generally low after release. To get a better understanding of what variables affecting migration success, Atlantic salmon smolts were studied during their out-migration in the old river channel in the lower part of river Umeälven. The area consists of shifting habitat and complex structures which causes difficulties for smolt on their migration out to sea. The aim of this study was to try to determine the effects of feed restriction, fin conditions and different physical barriers in the river, on the migratory behavior of Atlantic salmon smolts in the river Umeälven. The river was divided into six different sections using acoustic receivers strategically deployed along the river. Two-year old hatchery-reared smolts (n=150), in three different weight classes, were tagged with acoustic transmitters.

Composition of fractions from air-classified wheat flour

The unique ability of wheat to produce leavened bread is mainly due to the gluten proteins present. As consumers are more and more attracted to bread with high fibre content the use of wheat gluten will also increase in order to obtain bread with good volume and appetizing characteristics. Air-classification is a technological method used to separate particles by size and shape by means of air-streams into two fractions, fine and coarse. When used on wheat flour it is known to alter the flour composition in the fractions obtained compared to the original flour. This method is not widely used in the milling industry but could possibly be of interest if protein rich fractions with favorable protein quality can be produced.

Controlled traffic for grass silage production : an economic evaluation for dairy farmers

The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.

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.

Folkbibliotekariers användning av sökverktyg på webben i referenstjänst

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

Folkbibliotekens förmedling av Internetresurser: En undersökning av två mångkulturella länksamlingar.

The purpose of this Masters thesis is to investigate the role of link collections in Swedish public libraries mediation of Internet resources. The study is focusing on the effects on the contents and the structure in the link collections when the target group is immigrant users. This is done through literature studies completed with an examination of two link collections containing multi-cultural and multi-lingual material and qualitative interviews with the two librarians who are in charge of the collections. The major questions raised in this study are: What function do the link collections have for the public libraries? What is the difference in working with traditional, printed material compared to the work with Internet resources? And how are the selection of Internet resources and the structure of the link collections affected when the collection is intended for immigrant users? The main results are that link collections in public libraries can give a concrete form to political guidelines.

Individuell tillväxt och substratval hos en lokalt differentierad population av Asellus aquaticus

Local differentiation may occur during a short period of time and is part of the formation of new species. The isopod Asellus aquaticus is an example of a species in which local adaptation has occurred during a short period of time. An establishment of stonewort (Chara spp.) vegetation in Lake Tåkern (in the 2000) resulted in two different Asellus ecotypes; a lighter pigmented, smaller one that lives among stoneworts grazing periphytic algae, and a darker, larger ecotype that feeds on decaying leaves in reed (Phragmites australis vegetation. The purpose of this study was to examine whether there are differences in growth between ecotypes, depending on whether the food was periphytic algae or leaves, and to study the choice of substrates between the two food types. For the study, animals from both habitats were brought in from Lake Tåkern to the laboratory.

Häckar för Smålands inland : en översikt

Häcken är ofta ett självklart och naturligt element i en trädgård. Som trädgårds-ingenjör kan det vara svårt att välja en lämplig häck till ett gestaltningsförslag. Det krävs att vi tar hänsyn till flera parametrar, både för att häcken ska trivas men också för att kunden ska bli nöjd. Det kan därför ta mycket tid att leta upp en häck som uppfyller alla krav och önskemål som finns, tid man oftast inte har. Syftet med det här arbetet är att studera lämpliga arter för häckar till villaträdgårdar i det småländska inlandet. Arbetet har gjorts med hjälp av litteraturstudier samt intervjuer med plantskolor.

Mätmetoder och nyckeltal: en kvalitativ studie om hur bibliotekschefer mäter bibliotek

The aim of this master?s thesis is to examine how managers in some public libraries are using performance measurements and to what extent decision making is based on the results. The main questions posed are:??What performance measurements and indicators are used in the libraries examined???What is the attitude towards performance measurements among library managers???How and to what extent are performance measurements and indicators used in the process of decision making???What improvement would library managers wish regarding the development of performance measurements in public libraries?The theory is based on a model of evaluation of the public sector in addition to general steps of evaluation of quality and performance measurement results. The investigation is based on qualitative interviews with seven managers of public libraries in Sweden.

Utveckling av det peri-urbana landskapet : analyser i Kungens kurva

Genom att testa tre olika analysmetoder, och med hjälp av aktuell litteratur, studeras utvecklingspotentialen i det peri-urbana landskapet. I gränszonen mellan det urbana och det rurala finns ett landskap som känns igen genom dess industrier, shoppingcentrum och stora vägar. I dessa områden förkommer s.k. ickeplatser, som kan hittas mellan olika bebyggelseenklaver, på rivningstomter eller på f.d. parkeringar.

Den svenska äldrevården : Behov, konkurrens, kvalitet och valfrihet ur ett fastighetsperspektiv

In this thesis an explorative study was undertaken with the aim to study how a number of private care providers, as well as politicians and officials from councils in and around the Stockholm and Uppsala counties, think about the future of the Swedish elderly care from a property perspective, i.e. homes for the elderly. The analysis shows that there is a demand for capacity in 6 out of 16 municipalities, and that the property is an important part of this capacity, and the fulfillment of it. This was mainly due to the cost of capital, but also because of several other factors such as lack of land, a wish to guide the design, ideology, and in many cases a wish to use the property as an instrument of domination to control private health care providers.Also, the property was show to be connected to economic competition, to freedom of choice, and to quality. The problems related to the property in the market for elderly care still remains to be solved.

Värdeflödeskartläggning på ett tillverkande företag för att förbättra den interna leveransprecisionen

SammanfattningMed tanke på dagens marknad där allt större konkurrens finns gäller det att som företag ha en flexibilitet och lyhördhet som tillfredsställer kunden med rätt produkter, kvalitet och kvantitet. En låg leveransprecision kan orsaka problem i en verksamhets produktion, vilket innebär att företag bör kontinuerligt förbättra de interna processerna.Aros Quality Enclosure Systems AB (AQ AB), där projektet utfördes, är en del av koncernen Aros Quality Group. Företaget bearbetar plåtdetaljer och färdigställer produkter inom till exempel telekommunikation, bensinpumpar, kaffemaskiner och bankomater.Syftet med denna rapport är att presentera förbättringsförslag och rekommendationer som AQ AB kan genomföra för att förbättra den interna leveransprecisionen på den produkt som har studerats, den så kallade Ericsson-ram. För att uppnå syftet behövdes två frågeställningar besvaras, nämligen ?Vilka förbättringsområden i produktionen för Ericsson-ramar kan identifieras?? samt ?Vilka förbättringsförslag, utifrån de identifierade förbättringsområden, kan presenteras för företaget??.För att uppfylla detta syfte och svara på frågeställningarna har 14 besök på AQ AB i Vaggeryd gjorts.

Hälsorelaterad livskvalitet hos patienter med implantable cardioverter defibrillator : En litteraturöversikt

Syftet med denna litteraturöversikt var att beskriva den hälsorelaterade livskvaliteten hos patienter med en implantable cardioverter defibrillator (ICD).  Studien genomfördes som en litteraturöversikt, där tolv vetenskapliga artiklar av kvantitativ karaktär analyserades och användes i studiens resultatdel.  Sökorden som användes var Defibrillators, Implantable, Quality of Life och health related. Inklusionskriterier var artiklar skrivna på engelska, peer-reviewed, publicerade från år 2000 och framåt samt deltagarna i dessa studier skulle vara 19 år eller äldre. I studien framkom det att ICD-patienter undvek specifika platser, objekt och fysiska aktiviteter relaterade till ICD:n. Också en oro över bilkörning framkom.  ICD-patienter utsätts för en förändring i livssituation och är i behov av stöd och individuell informationsgivning gällande deras medicintekniska anordning.

Bakterietillväxt i strömedel till mjölkkor

The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores. In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied. Most bacteria need humidity and prefer a quite high water activity to be able to grow.
