Kan mjuka golv i grisningsboxar minska skador på klövar och ben hos smågrisar?

The incidence of damage to the claws and legs in piglets caused by the floor in farrowing pens is a widely known problem and very common in today's pig herds. Although the association between floor and damage has been known for over 35 years, no suitable solution has been found to reduce the negative impact. The purpose of this study was to make a literature study to document the experiences of the use of different types of flooring in farrowing pens and also, in an own study, examine if soft floor in farrowing crates could lead to reduced damage to the claws and legs in piglets compared to concrete floor. The study was conducted in two herds, A and B. In each herd, farrowing pens with concrete floor and concrete floor with polyurethane coating were compared.

The overall aim of this study is to examine how Swedish women?s youth- magazines describes women. Through a social constructivist perspective, this essay particularly focuses on how the magazines deals with issues of gender and sexuality and what norms they reproduce. The magazine?s image of the young Swedish woman is a somewhat complex one, although one thing is strikingly clear: she is very different from men.

Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv

In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.

Installation av ny nätverksstruktur i datacenter: Ett examensarbete på Facebook Data Center, Luleå

Under fem veckors tid har jag utfört mitt examensarbete på Facebook Data Center i Luleå. Målet med arbetet var att installera ett internt nätverk som skulle ersätta ett annat internt nätverk. Bakgrunden till arbetet är att nätverket som redan existerade i datacentret (innan bygget överlämnades till Facebook i Luleå) hade en omodern nätverksstruktur. I arbetet avsattes tid till inläsning av plattformarna för routrar och switchar. Dessa enheter monterades senare upp i respektive rack.

Artificiella sötningsmedel i dryck och dess effekt på hungerkänslor och energiintag

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.

Företagsmodell för byten av systemutvecklingsmetod : från vattenfallsmodellen till Agila metoder

As changes occur more frequently in IT- and software development, it is important for the companies to meet the demands and needs of its customer. The companies have to be able to adapt themselves continuously in order till fulfill its customers changing needs in an effective way, which results in big changes of the companies? structures. The more traditional way of working is often replaced with more alternative approaches as a response to the reputable deficiencies of its predecessors. As an effect of the rapid change and development some companies now see big potential in switching to more Agile and flexible methods and some companies have no choice but to change their way of working.

Läsk - flytande kalorier / Soft drinks - liquid calories

Bakgrund Idag diskuteras det mycket kring vilken roll sockerkonsumtionen kan spela gällande de ökande hälsoproblemen i samhället. På senare tid har det flytande sockret lyfts fram som en av de stora bovarna i dramat och forskning visar på att läsk bestående oberoende av vanligt socker eller artificiellt socker, kan påverka hälsan negativt. Syfte Syftet med undersökningen var att granska ungdomars läskkonsumtion samt att ta reda på deras motiv till varför de föredrar att dricka vanlig läsk respektive lightläsk. Det är även av intresse att undersöka eventuella könsskillnader. Metod Undersökningen har gjorts med hjälp av en enkätundersökning med intention att beskriva ungdomars läskkonsumtion. Valet av undersökningsmetod syftade till att ge bredd åt undersökningen.

Robotstyrning med metoden Sliding Mode Control

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.

Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.
