Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Artificial sweeteners in beverage and their effecton hunger and energy intakeAuthor: Sofia Andersson and Sofia JakobssonSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2012BackgroundIn 2010 the total consumption of soft drinks in Sweden was estimated to 69 litres per person and17 % of the domestic production was estimated to consist of soft drinks sweetened with artificialsweeteners. The effects of artificial sweeteners on hunger is not yet fully understood. It isspeculated that they might increase hunger and hence increase energy intake.ObjectiveThe aim was to compile the evidence regarding the effects of an intake of a beverage sweetenedwith artificial sweeteners compared to sucrose on subsequent hunger and energy intake.Search strategyA systematic search for literature was performed in the databases PubMed and Scopus.Selection criteriaThe inclusion criteria were RCT, human studies, articles published in Swedish or English, studieson healthy adults and studies measuring hunger with a subjective scale or energy intake. Theexclusion criteria were studies who measured energy intake under other forms than standardisedor controlled, studies without a standardised dose of the beverage and articles needed to beordered against payment.Data collection and analysisFour articles were selected and examined according to a template developed by SBU. Theevidence for each outcome was weighed together and graded according to GRADE based on asummarised evidence form developed by the Sahlgrenska Academy.Main resultsAll four articles measured subjectively rated hunger.

Bakgrund: Bonussystem är något som började växa fram under 1980-talet och är ett inte sällan förekommande debattämne. Inte minst i dagens situation med en stark recession och en finansiell kris om knuten. Flertalet artiklar har tagit upp ämnet, där man har ifrågasatt olika företags utdelning utav enorma rörliga ersättningar trots den svåra tid vi nu befinner oss i. Företagen motiverar olika andledningar till varför de väljer att betala ut bonusar till sina vd:ar, som grundar sig på olika typer av variabler.Syfte: Uppsatsens syfte är att undersöka vilken typ av variabler som visar starkast korrelation med storleken på företagsledarnas bonusar, och att se om dessa kan tänkas påverka deras risktagande.Metod: Uppsatsen bygger på en kvantitativ undersökning av sekundärdata som har inhämtats från de utvalda företagens årsredovisningar. Undersökningen tar en deduktiv ansats, där de valda teorierna appliceras på de resultat som undersökningen visar.Resultat: De fem företagen som betalar ut högst total ersättning är ABB, Ericsson, AstraZeneca, Getinge och Scania.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

The aim of this essay was to describe and interpret the managements and organizations impact regarding the caregivers working conditions. To examine this we used a qualitative method. We completed two group interviews and five individual interviews with a total of fifteen enrolled nurses that worked within elderly care. In our interviews we found that the enrolled nurses felt that the organizations economic interests collided with their personal values regarding good quality elderly care. We also found that the caregivers experienced that they had an impact on their working conditions and that their employer was the main reason for making it possible..

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one hour?s pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand.

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

AimThe aim of the present investigation was to study the side distribution (right, left) and possible gender differences in terms of anterior cruciate ligament (ACL) injuries in different sports.MethodThis Register study comprises a total of 27856 subjects from the Swedish National Anterior Cruciate Ligament Register. Side- distribution and possible gender differences were analyzed. The different sports consisted of aerobics, alpine skiing, basket, cross-country skiing, dancing, enduro, floorball, gymnastics, handball, ice hockey/bandy, martial arts, outdoor activities, racket sports, snowboard, soccer, and volleyball. Due to injuries that had occurred in the traffic and at work 5076 subjects were excluded. Statistical data have been analyzed with one way ANOVA and x2 test and the Tukey post hoc test has also been used.

In Dar es Salaam, as in many cities in developing countries, green areas are decreasing due to the fact that the growth of buildings, infrastructure and services has become a priority. As the population increases more buildings and infrastructure are needed and much of the building activity takes the form of uncontrolled settlements, which encroaches the public green space. Dar es Salaam has approximately three million inhabitants, of which about 70 percent are living in informal settlements. The aim with this study is to make a design proposal for a park and recreation area where the Msimbazi river basin in the centre of Dar es Salaam is today. The basin consist of a few playing fields, footpaths and some urban farming, but apart from this it mostly consists of unused grasslands, swamps and forests. Because it is an unsafe place and badly connected to the rest of the city infrastructure, it has become a barrier. The annual flood combined with the constant still shallow water creates a good breading ground for malaria mosquitoes.

A high amount of dead wood is one of the most important prerequisites for high biodiversity on forest land in Sweden. Dead wood is most abundant in young forests, thinned forests, woodland key habitats and protected forest land. In old-growth forests most of the dead wood consists of logs and snags, whilst in managed forests a huge proportion of dead wood is made up of logging residues like stumps and FWD, fine woody debris (< 10 cm diameter). All these different types of dead wood may serve as substrates for epixylic bryophytes and lichens. However, few studies have been conducted on the relative importance of these different fractions of dead wood for the occurrence of bryophytes and lichens, especially when considering dead wood on thinned forest land.

The aim of the present study was to investigate the effect on growth of foals on two different diets, either a forage-based diet or a diet containing approx. 40 % concentrate. The report also includes a review of the pertinent literature on the effects of diet on mares? milk and growth of horses. The hypothesis of the study was that a forage based diet will result in a similar growth pattern as a diet including more concentrates if the diets contain the same amount of energy, crude protein, lysine, calcium and phosphorous.

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net calledströmöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.
