The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

The ability to detect protein-based biomarkers, which are linked to different diseases like colorectal cancer, is very important as a diagnostic tool. Usually complex biological samples like blood are studied which will contribute to different technical issues when performing an assay. The aim with the project is to optimize and develop the high throughput protein detection technique Proximity Extension Assay, PEA, into a 96-plex panel, in hopes of discovering an expression profile for colorectal cancer. PEA was developed by Olink Bioscience and allows specific proteins in a sample to be quantitatively transformed into nucleic acid sequences that are subsequently detected and quantified with real-time PCR. Two proximity probes containing oligonucleotide sequences bind pairwise to target protein and when brought in proximity, a DNA polymerase will extend a hybridization arm from one probe over to the second forming a double-stranded DNA sequence that can serve as a template in real-time PCR.

Private state aid enforcement with respect to below market value transactions carried out by Swedish municipalities ? A study on the conformity of Swedish procedural and substantial rules with the principle of effectiveness of EC law Recently in Sweden, several local governmental entities (municipalities) have engaged in commercial transactions that, essentially, have been aimed at transferring the ownership of public services ? for example schools and local medical care centers ? to private undertakings. A few of these transactions have been declared by Swedish administrative courts to constitute illegal below market value transfers of public resources. The essay seeks to determine whether the Swedish national provisions that govern legal claims based on the directly effective Art. 88(3) of the EC Treaty, are compatible with the principle of effectiveness, i.e.

StoraEnso decided in year 2002 to build a pulp mill in the province of Guangxi, southernChina, and also establish eucalyptus plantations to provide it with raw material. By 2010StoraEnso controls about 90 000 of planned 120 000 ha, out of 75 000 ha is already plantedwith Eucalyptus.By using better genetic material, improve the tending, selecting the sites more careful and byusing a proper fertilization regime StoraEnso hopes to increase the mean annual incrementfrom today?s 25 m3/ha, on bark, to 35 m3/ha. This study is one part in this work to increase themean annual increment in the plantation.This master thesis is the forth in a series, that has followed up a fertilization trial that startedin spring 2006 when the trial was laid out and treatments decided. The aim with the trial is toexamine the production potential of Eucalyptus urophylla in Guangxi, southern China.

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

Syftet med studien var att undersöka skillnader i stress, återhämtning samt coping hos individer som genomfört tävlingsinriktad diet jämfört med de som dietat av icke-tävlingsmässiga skäl. 86 individer (64 män och 21 kvinnor) deltog där medelåldern var 25. Metoden i studien var kvantitativ och bestod av ett tredelat formulär innehållandes de svensköversatta instrumenten Recovery-Stress Questionnaire for Athletes (RESTQ-Sport) (Kellmann & Kallus, 2001) och Brief COPE (Muhonen & Torkelson, 2005), samt ett egenkomponerat formulär där informanterna fick kategorisera sig som en av tre diettyper: I) Bodybuilding (BB, n=26), Annat tävlingssammanhang (AT, n=32) samt Icke-tävlingssammanhang (IT, n=28). Resultatet visade en statistisk skillnad i stress mellan de olika diettyperna, där BB upplevde mer stress jämfört med IT, samt att BB upplevde mer av stressdelskalan utmattning än IT. De implikationer som framhävts har riktat sig mot att sprida en bättre förståelse för återhämtning hos dietister inom allmänvård likväl som dietcoacher inom bodybuilding..

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

The characteristic of services as an effort carried out in a "moment of truth" implies a risk for failures. This study sheds new light on how alternative offerings that customers are initially exposed to can affect satisfaction and loyalty in the service failure and recovery context. More specifically, two aspects of the initial offering are studied: promised general service quality and the presence of a promise about a specific product attribute. Based on a presentation of the main theoretical perspectives, hypotheses are formulated and a scenario-based experiment in a hotel setting is designed to explore these. The results indicate that a higher level of promised service quality can result in more positive evaluations of satisfaction and stronger word-of-mouth intentions than for a lower level of promised service quality.

This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF). The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF. The number of open water bodies in the Swedish landscape has substantially declined during the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.

Syftet med studien var att studera hur fenomenet självläkning framställdes i nationell och internationell forskning. Studien omfattar tre frågeställningar: (1) Hur definieras alkoholmissbruk i artiklarna? (2) Hur definieras självläkning i artiklarna? (3) Hur framställs självläkningsprocessen i artiklarna? För att besvara dessa frågeställningar gjordes en selektiv kunskapsöversikt och en kvalitativ innehållsanalys användes som metod. Kunskapsöversikten utgjordes av tio forskningsdokument vilka omfattades av kvalitativa och kvantitativa undersökningar mellan åren 1996-2007. Studiens position är postmodern.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
