Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

There are reasons to believe that recent changes in the Swedish academic library environment create new images of identity. New information technology, changed educational methods and increasing numbers of students in higher education heavily influence the professional basis for librarians. The purpose of this essay is to examine and describe how the images of identity are conceived and expressed by staff in two university colleges in Sweden, Malmö University and Södertörn University. We define identity as the images of what the library is, what it is aiming to be in the future, what it should do and how. In a qualitative study attitudes towards and opinions of the role of the library in the university environment are investigated.

In this thesis, the flows of Reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

Bakgrund: Läckage av fostervatten i fullgången tid utan att värkarbetet börjar, benämns PROM (Prelabour Rupture of the membranes). Förtidig vattenavgång förekommer i mellan 6-19% av alla graviditeter. Därför är det viktigt att barnmorskor har kunskap från den senaste forskningen om handläggningen av PROM. Syfte: Att genom studie av publicerad forskning identifiera optimal behandlingsmetod vid PROM efter graviditetsvecka 34+0, singelgraviditet och barn i huvudändläge. Metod: Beskrivande systematisk litteraturstudie.

Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater treatment from scattered households with unsatisfactory purification. Blast furnace slag is a by-product from iron production, and has in laboratory trials showed good phosphorus binding capacity. To test blast furnace slag as a Reactive filter media for phosphorus separation in a full scale experiment, a wastewater treatment plant has been built behind the picnic area at Ångersjön alongside the road E4 in central-eastern Sweden. The plant contains two parallel lines, one with blast furnaces slag and the other with Filtralite-P as phosphorus sorbent. Both filters have showed decreasing phosphorus purification effect with time in spite of a low wastewater load.

Lagstiftning och normgivning kring årsredovisningen, vill skydda intressenter mot felaktig och bristfällig information. Det finns en del i årsredovisningen som inte är lagstadgad, den benämns frivillig information. Omfattning och val av vilken frivillig information som företag väljer att redovisa beror till stor del på vilken redovisningsstrategi som företaget tillämpar.Syftet med uppsatsen är att beskriva och analysera vilken redovisningsstrategi som svenska aktiebolag noterade på Stockholmsbörsen tillämpar, när de redovisar frivillig information i årsredovisningen. Vidare är syftet att undersöka vad som påverkar val och utformning av redovisningsstrategi, vi utreder huruvida anlitad revisionsbyrå är en förklarande variabel, samt om det finns andra aktörer och faktorer som påverkar.Vi har undersökt variablerna; anställda, kreditgivare, aktieägare, andra företag noterade på Stockholmsbörsen, branschkollegor, anlitad revisor och Vd/företagsledning, för att utreda om dessa aktörer och faktorer påverkar valet.Både en kvantitativ och kvalitativ metod har använts för att uppfylla uppsatsens syfte. Genom en enkät, via e-mail, till företagen i vårt urval, har vi undersökt i vilken utsträckning de olika variablerna påverkar samt huruvida det leder till att en viss redovisningsstrategi tillämpas.

?Rätt avlopp på rätt plats? ? Livscykelanalys av tre enskilda avloppsanläggningarProblemen med övergödning i Östersjön och i Sveriges insjöar är stort och enskildaavlopp pekas ut som en central aktör, framförallt beträffande fosforutsläppen. I Sverigefinns det ungefär en miljon enskilda avloppssystem och nästan hälften av dessa har enså pass bristande vattenrening att de inte uppfyller gällande lagstiftning. Utvecklingenav nya tekniker för rening av avloppsvatten har länge strävat efter att minska utsläppenav övergödande ämnen, detta ibland på bekostnad av andra utsläpp, så somväxthusgaser och försurande ämnen.Det här examensarbetet har därför med hjälp av metodik från livscykelanalys (LCA)utvärderat tre enskilda avloppssystem med tanke på deras utsläpp av växthusgaser,försurande gaser samt övergödande ämnen. Då misstanke också fanns att de lokalaplatsegenskaperna påverkar de enskilda avloppssystemens totala miljöpåverkan,utfördes även en intervjustudie med ett antal av landets kommuner.

Övervikt hos hund är ett växande problem med en rapporterad incidens på 22-40 %. Tillståndet definieras som ett överskott av fettvävnad i kroppen, beroende på rubbad energibalans. Överviktiga individer drabbas ofta av sekundära hälsoeffekter så som diabetes mellitus och insulinresistens, andningsbesvär, förhöjt blodtryck, ortopediska tillstånd och njurproblem. Överviktiga hundar har även kortare livslängd än normalviktiga hundar. Överviktiga hundar har abnormala lipoproteinvärden med högre plasmakoncentrationer av både triglycerider och kolesterol jämfört med normalviktiga hundar. De har också en rubbad balans av så kallade adipokiner som utsöndras av fettvävnaden.

Trade was assigned as a Community responsibility at the founding of the European Community in 1957. It was then recognized that Europe would achieve a greater international influence if it were to negotiate trade deals with one voice. Since then, the basic rule has been that the European Commission negotiates agreements on behalf of the EC, and presents the agreements negotiated for approval in the European Council. Today, the 25-member European Union is the largest trading power in the world, and most member states have decades of experience of coordinating their national trade interests into a common position. However, partly as a result of the complex nature of the trade decision-making processes it is sometimes problematic to identify who or what really influences EU trade policy.

Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more Reactive and also has less visibility.

Political scandals are constantly abound in the media, rulers face the global tribunal of the mass media and are forced to defend their actions and above all, their position in society. This essay concerns itself with that defence ? more specifi- cally with the defence of four Swedish politicians in high office during four different scandals. Gudrun Schymans? eva- sion, Laila Freivalds? dealing with the tsunami disaster in Thailand, Annie Lo?o?fs? tangle concerning representation notes and public documents and Tobias Billstro?ms? statements concerning undocumented immigrants and asylum seekers.

Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.

In a business environment where the stakeholder perspective is evolving and sustainable development is receiving increased attention, it is of importance for companies to adjust. The demand and pressure is exerted from several stakeholders who force companies to take action and live up to the expectations because if failing to do so, negative consequences will most likely be the case. The attention of this study is on ABB Power Products (ABB PP) and their environment and working environment risk management. The aim of this thesis is to identify and describe how perceived environmental risks are managed and what the incentives are to work proactively to minimize the risks. The incentives for a proactive risk management strategy are researched through both a strategic and operational perspective.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.
