Behaviour and throughput of dairy cows when entering and exiting two types of parallel rotaries
Today a trend can be seen towards fewer dairy farms and increasing number of cows per farm. Larger farms set a higher demand of more labour efficient milking systems. The time to enter and exit milking rotary platforms is crucial to maintain a high cow throughput. This study is a project initiated by DeLaval in order to evaluate the cow throughput and cow behaviour during entry and exit in two types of parallel external rotaries with different bail designs. The two rotaries compared were DeLaval parallel rotary PR2100 and PR3100HD.
Sensory studies of an energy dense drink for elderly people
The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition.
Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health
care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious
foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly
consumers as a strategy to prevent malnutrition among elderly.

Generationsfonder : En jämförelse mellan generationsfonderna i Sverige
In the future the Swedish pension system will face major problems. With an increasing aging population combined with a decreasing share of working population the financing of the pension system is becoming a bigger problem than previously predicted. This means the individual himself will have a bigger responsibility to invest money for their future retirement. It has been shown that a large proportion of the people who invests for their future pension have neither the interest nor the time to actively invest their pension capital. To make it easier for those who invest for their retirement, some Swedish banks have created so-called generation funds.
GRÖNYTEFAKTOR I ETT NYTT PERSPEKTIV - Går ekosystemtjänster att mäta med fjärranalys?
Due to an increased population in cities the need of densification of cities increases. This means that the amount of ecological elements in the city is at risk of decreasing. Ecological services contribute to the city?s climate by softening the negative impacts that densification of cities means. Thus increases the will and ambition in city planning in to preserve greenery.This is an interdisciplinary thesis within the subject of geography that studies Biotope Area Factor (BAF), a planning tool that is used in city planning with the purpose of compensating for lost ecological services associated with new housing estate.
Björkbarksextrakt, BBE : en lönsam lösning på betningsproblematiken?
The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below.
Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment.
Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator
Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.

Segregation is widespread in Sweden today and the exclusion that it creates needs to be broken.
The aim of this paper is to examine if it is possible to promote integra-tion through physical planning.
