Lamellrandsröta i hästhoven :

SAMMANFATTNING Jag har skrivit om en hovsjukdom som drabbar hästar, den engelska benämningen är White line disease. Det finns inget korrekt namn på svenska, men vi kallar det för lamellrandsröta. Den engelska benämningen är den mest använda. Sjukdomen kom in i Sverige i slutet av 1980-talet, man tror att det var via importerade travhästar från USA. När den i slutet av 1990-talet fick fart i Sverige började den också att bli ett problem. Ambitionen är att få en inblick i vad lamellrandsröta är och vad den samlade kunskapen är idag bland fackfolk och praktiker. Godtyckligt har jag valt ut och ringt runt och intervjuat ett antal personer som har stött på detta problem, hovslagare, veterinärer och hästägare. All fakta som inhämtats har jag sammanställt, men det finns fortfarande många frågetecken att reda ut. Ett bekymmer är att expertisen har så varierande kunskap och syn på sjukdomen. Idag vet man att det är anaeroba (syreskyende) organismer som orsakar rötan.

Utveckling av licenshanteringssystem för kontroll av programåtkomst

Ett system utvecklades för företaget Monitor i Hudiksvall. Syftet var att skapaett system som kan kontrollera vilka funktioner ett program kan komma åtutifrån den licens som kunden har betalat för, i form av en licensfil. En analysav företagets befintliga licenshanteringssystem gjordes för att identifiera vilkaproblem som behöver lösas i det nya systemet. Arbetet har använt en agilmetod med små inkrementella leveranser och ständig kundkontakt. Eftersomsystemet fungerar som ett API och använder sig av nätverkskommunikationöver potentiellt osäkra nät, har kryptering av datatrafik med tekniken SSL/TLSanvänts.

Växthusvävens fukttransmission ? Hur struktur och materialval påverkar växthusvävens fuktgenomsläpplighet

Växthus används för att ge ett bättre odlingsklimat åt grödor och växter. För ytterligare förbättring av förhållandena används växthusvävar som exempelvis kan reglera temperatur, fuktighet och ljustillförsel. Väven som behandlas i denna rapport är en så kallad energiväv som främst har till uppgift att minska energiåtgången vid uppvärmning.När väven är fördragen nattetid, ökar luftfuktigheten då grödorna avger fukt dygnet runt. Fukten kan kondenseras mot energiväven, vilket gör att det bildas droppar på väven som kan falla ned på växtligheten. Den höga luftfuktigheten kan medföra svampsjukdomar och i övrigt också bidra till att tillväxten avstannar.

The High Line : hur väl fungerar promenadstråket som grön kil i New York City?

This study was made to compare construction companies for gardens way to work with up following, with purpose to see if there was an efficient and not resource demanded system which gave much value. To achieve the purpose a case study was made. The delimitation for the case study was only to compare the work with up following on individual project. The delimitation on the companies in the study was from ten to sixty employees. That because to reach companies were it´s not the same person how calculates on tenders and than perform the projects. The study was delimitated to the west side of Skåne. T o be able to compare the companies and to find trends, an interviewguide was made and was used during the interviews with the companies.

Centraliserad personalavdelning- bästa verktyget för chefsstöd? : En kvalitativ studie om arbetssituationen relaterat till chefsstödet från personalavdelningen vid Uppsala kommun.

Changes in the workplace have led to new ways of organizing and structuring organizations. Organizations? desire to increase competitiveness, efficiency and flexibility has resulted in new conditions in the field of human resources. The new conditions have also created new roles and changing responsibilities for those working within human resources.The purpose of this study was to investigate how the implementation of Ulrich's model for HR transformation can impact on the human resource departments managerial support to first-line managers in the municipality of Uppsala. Today the municipality of Uppsala organizes its human resources based on the Ulrich's model, which divides the work into the units service center, the expert unit and business partners.

Modernisering av driv- och vändstation för timmersortering

The purpose of the rebuild of Notnäs AB timber sorting line is to renew the existing drive and turning ends of the transport chain, which has become old. This means that Notnäs AB have problems to get new parts if the gearbox and chain are worn out. They also require that the rebuild should have a maintenance schedule for the new spare parts that will be used in the rebuild. Maintenance workers placed great emphasis on that in a rebuild it shall be a service-friendly design. The maintenance schedule used in Notnäs AB in the current situation is from Statoil and the report uses SKF formulas and recommendations in order to obtain a lubricating schedule.

Hjulspår på banken : En kvalitativ fallstudie om vägarna mellan lean och motivation hos anställda i tjänstesektorn

Background: Since the coining of the phrase lean production by Womack, Jones and Roos in 1990, this mass production system of Japanese origin has been implemented in a multitude of organizations throughout the world, the results being predominantly positive from a financial point of view. The possibly negative effects of mass production on worker motivation have been discussed since quality of work life became an important political issue in Sweden in the 1970?s. As the popularity of lean service is now increasing, there are still unresolved issues regarding the transferability of a mass production system to the service industry, particularly with regards to the motivation of service employees.Purpose: The purpose of our thesis is to study the lean system of a Swedish bank, SEB Way, from a management- as well as an employee perspective in order to describe how lean may affect the work motivation of service employees.Research procedure: The study is empirically based on observations and interviews on multiple hierarchical levels at SEB. We have conducted a total of 13 interviews with front line employees at SEB, with the central SEB Way team as well as two external lean specialists.Results: The study indicates that SEB Way has little direct influence on the intrinsic work motivation of the SEB front line employees, as work motivation was present prior to the implementation of lean.

Hållbarhetsreovisning : the Global Reporting Initiative, erfareheter och framtida scenarior

The history of environmental reporting began in the early 1990?s when some companies included the environmental issue in their annual report. The increased interest of ethical and sustainable investments and demands from different stakeholders conjure a change of the report design. To develop the environmental reports and create design guidance for sustainability reports an organisation called Global Reporting Initiative (GRI) was born. The GRI is environmental reporting taken to another level, a level that is according to sustainable development.

Emerging zoonotic viruses : what characterizes them and what are the risk factors for their emergence?

Emerging infectious diseases poses a great future threat, not only to humans but also to domestic animals and wildlife. Even though the majority of these infections only cause minor health problems, the relatively recent emergence of HIV clearly illustrates that the next major human pandemic may surface at any time. Regardless of what the name indicates, most emerging human pathogens are not believed to be recently evolved, but to have existed previously in the natural environment. Most emerging pathogens are zoonotic, i.e. able to infect animals besides humans.

4-1BB is up-regulated in human mast cells, when exposed to tumor conditioned medium

Mast cells have for a long time been known to accumulate around tumors (Maltby et al., 2009). Studies show that they may be important and sometimes essential in tumor angiogenesis, tumor growth and metastasis of tumors (Soucek, et al., 2007; Xiang et al., 2010). In an expression array study (Wensman et al, submitted manuscript) performed on mouse mast cells exposed to tumor conditioned medium, the gene 4-1BB was among the most up-regulated genes compared to control medium. 4-1BB codes for a membrane receptor protein of the tumor necrosis factor superfamily and has been shown to be important in T cell regulation in tumor diseases. This study was performed to investigate if human mast cells up-regulate 4-1BB when they get exposed to tumor conditioned medium.

Läraren och tjänstemannauppdraget : En studie om lärarstudenters syn på sina framtida tjänstemannauppdrag

The aim of this essay is to examine how future upper secondary school teachers within social science comprehends their future proffessional role. The aim is also to see whether the education is of importance to their suspension for their future professional role. Focus will especially be on the teachers civil servant role, where the aim is to see how their identification suspends to the governmental expectations on their future civil servant misson. The essay is based on a qualitative method, which is focused conversational interviews.The result indicates that future upper secondary school teachers within social science, who are about to finish their education, have a somewhat deeper sense of identification with the teachers civil servant mission compared to those in the beginning of their education. The result also indicates that the future upper secondary school teachers identification are in line with the governmental expectations on their civil servant mission.

VD-ersättning och ägarkoncentration: En studie om ersättningsnivåerna i svenska börsbolag

This study examines whether the ownership structure of Swedish firms contributes to explain the variations in executive pay. A regression analysis was performed on 102 companies listed on the Stockholm Stock Exchange. The analysis suggests a negative relationship between ownership structure and executive pay after taking company profitability and size into account. The result is in line with previous studies and the agency theory. This indicates that large shareholders have a stronger position in Swedish companies or that large shareholders monitor the management to a larger extent, rather than providing incentives.

Optimering av sintrade kugghjul

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

Enegiutredning Hotell Princess

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.
