Vanliga helminter hos hund, katt och häst i Sverige : artbeskrivning och laboratoriediagnostik

This report includes common helminths, symtoms, routes of infection, diagnostic laboratory techniques and prophylactic methods to prevent infection. We have pointed out where there is a risk of zoonotic transmission and how to avoid contamination and infection. We have restricted the number of species to the most common helminths. Some of these helminths do not naturally occur in Sweden (yet) but are nevertheless of current interest when we travel across borders with our horses, dogs and cats. The diagnostic part of our report tells about different techniques to find an occurance of helminths in samples of faeces, blood, urine or saliva from a horse, dog or cat. We also write about some recommendations on treating parasitic infections and the development of anthelmintic resistant helminths that originates from incorrect use of anthelmintic drugs .

Elektriskt system för detektion vid ballistiskt prov

The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.

Strategi, Läge & Varumärke

Goal: To describe which evaluation method is used by Swedish retailers to assess a potential retail location and to describe to what extent the retail brand effects this strategic decision. Design: Analysis of ten interviews with companies within five retail sectors in Sweden. Main study: Indication of what methods are used to evaluate a location and how a company's retail brand affects the decision. Results: Retailers use a mix of theoretical methods to evaluate the location attributes and possible profit. Most common among mixtures was an application of the analog method, residual method or the checklist method in combination with a financial assessment.

Utvärdering av Transportstyrelsens flygtrafiksmodeller

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB

Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.

DISA-metoden : En undersökning om gruppledarnas bedömningar av genomförandet och av metodens framtidsutsikter

Twice as many women as men suffer from mental ill-health. The negative trend of mental problems among teenagers continues. In certain places in Sweden, 40 per cent of the teenage girls have outspoken symptoms of depression. This is why it is important to observe mental ill-health in a public health perspective. One effect evaluation of the DISA method (Depression In Swedish Adolescents) drew the conclusion that this universal depression preventive method is well working. The DISA method includes cognitive behavioural techniques that change negative pattern of thinking, give practice of communication, strategies of problem solution plus exercises to strengthen the social network.

Skola och kompetensutveckling, viktiga faktorer för socialisationsprocessen : En studie om ensamkommande barns socialisation i deras nya samhälle

The study discloses unaccompanied children´s socialization in their new society. The purpose of the study is to investigate how unaccompanied children's schooling is an important factor in their socialization and skills development in their new society. For example, we have chosen to illustrate how their school works and if and whether the teachers receive the support they need in order to help children develop their skills so they can find their way in society. The research is based on three different methods. The first method is based on literature research.

Det praktiska intellektet: timmerlagning med mallbr?da som exempel

This thesis presents a method of making repairs in log houses. The purpose of the thesis is to use this method to exemplify crafters practical intellect. The method is based on the use of a template board to transfer the measurements onto the new log. There is a dearth of literature dealing with timber repairs, and the literature regarding using a template board for this is non-existent. The description of this method has therefore been compiled from interviews with active timber crafters.

Ett undervisningsförsök att skapa meningsfullt lärande i frisörens grundläggande tekniker

This Independent work is about testing a method to create meaningful learning and a deeper comprehension in matter of basic hairdressing techniques. I got the idea for this method by reading literature related to my education to become a teacher for hairdressers, the new schoolreform and from my own experience of a teaching method that I saw an opportunity to develope. My teaching method was based on first teaching the pupils the basic techniques, and then give them an assignment were they were to find out their own final result by using a picture for inspiration. They were given an assignment description with certain frames but with freedom of choice how to get to their own final result. By making a job description and a headdrawing to show how the work should be done, and during the process try different ways to achieve the best result, my idea was that a deeper understanding and a feeling of meaningfulness would appear.The result shows that the pupils by freedom within frames experienced meaningful learning and thereby deeper understanding when it comes to basic hairdressing techniques.

Evaluation of Ectopar for the control of the poultry red mite Dermanyssus gallinae

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

Framtidens bioinformatikstöd för forskargrupper : En studie av SciLifeLabs användarstöd

Science for Life Laboratory:s (SciLifeLabs) användarstöd inom bioinformatik brister inom en del områden som användarutbildning, organisation och kommunikation. För att kunna tillgodose den snabba utvecklingen av biotekniken (till exempel nästa generations sekvensering) och inte minst SciLifeLab är det viktigt att dessa brister åtgärdas. Efter att ha utfört en serie intervjuer med användare och leverantörer av SciLifeLabs sekvenseringstjänster har vi kommit fram till sex förslag för att täcka problemen inom de olika områdena. Förslagen sträcker sig från att vara enkla till mer omfattande att implementera. Resultaten är riktade mot SciLifeLabs sekvenseringsplattform och är utformade för att kunna implementeras i dagsläget samt anpassas till framtida utvecklingar. Vi tror också att förslagen kan, med enkla modifieringar, användas av andra plattformar hos SciLifeLab..

The choice of method was depth interviews with respondents from a targeted sample of Swedish banks. These respondents were chosen based on the knowledge they possess as key employees in the capital requirement process and their involvement in choosing their banks? method for calculating the capital requirement.

Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.
