Pigs kept for meatproduction are often surgically castrated to prevent aggression and boartainted meat. Castration without analgesia and anesthesia is painful and causes a lot of stress to the pig. There are alternatives such as to surgically castrate the male pigs with analgesia and/or with anesthesia, immunocastrate or keep them as intact males. In Sweden the most common practice is to surgically castrate the pigs before they are seven days old. The impact on the pig is that the incision causes pain and stress, which may lead to changes in behaviour, reduced appetite, reduced growth and a higher risk of infections.

Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.

Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter distances, but not necessarily. In the wake of urban density the greenstructures of the city is shattered. The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

The costs of logging and of transportation with truck are dominating the total cost of wood delivered at industry. To support the profitability for the members' forestry the processing and handling with the timber has to be as efficient as possible. Increased length of pulpwood in thinning is one conduct that can result in higher productivity and/or lower costs. The study is scaled as a system analysis with the aim to exemplify the differences between working with 3- and 4-meter as standard length of pulpwood, related to biological aspects, timber receipts, cost of logging and cost of transportation with truck. Important aspects are if the change is technically and biologically feasible and economically profitable.

This study was made to compare and distinguish any differences in olfactory recognition and host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The populations used were established in Egypt and Benin, Africa. The documentation consisted of information about (1) each of the strains development through the larval stage up to pupation on diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton, clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any possible responses to plant volatiles. Throughout the diet experiments the larvae from the Benin strain showed significantly a better development between artificial, clover, cowpea and cotton respectively, while the Egypt strain had significance between artificial, cotton and cowpea/clover as diet. Also noted was how the strains substantial development of weight differentiated if fed the cotton diet, followed by the cowpea diet showing that the Benin strain would develop a higher body mass on a cotton diet as well as on a cowpea diet. This trend was however switched once the pupal stage was reached, where the Egyptian strain contained a significantly greater body mass than the Benin strain on the artificial and the Benin strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly better on cowpea while the Egypt strain develops better on an artificial diet. During the oviposition experiment that both stains showed a clear difference in hierarchy of host plants considered suitable for oviposition, where the Egyptian strain is significantly more attracted to clover than the Benin strain. Also showed with electroantennographic recordings and significant values was the higher sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate, Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

Med utgångspunkt i George Lakoff och Mark Johnsons teori om den konceptuella metaforen analyseras i denna uppsats bildspråket i opionsjournalistiska texter som behandlar frågan om individualiserad föräldraförsäkring. Därtill anläggs med hjälp av Yvonne Hirdmans teori om genussystemet ett genuserspektiv, för att undersöka om metaforerna är könade och/eller reproducerar det binära könstänkandet. Materialet är hämtat från DN, Aftonbladet, Expressen och SvD under perioden januari 2010-novmeber 2013. .

Uppgiften för projektet var att rita en varvsbyggnad på den västra delen av ön Beckholmen i Stockholm. Varvsbyggnaden är menad åt ett reparationsvarv, som utför reparationer av de medelstora till större fartyg som trafikerar Stockholms skärgård, och ska göra det möjligt för verksamheten att utföras klimatskyddat året om.Den ritade byggnaden strävar efter att möjliggöra ett fungerande varv med maximal kapacitet. Därför har de maskiner industrin använder sig av integrerats i byggnaden och tillåtits påverka byggnadens utformning.Byggnaden består av en platå i betong ovanpå vilken mindre fartyg kan placeras genom användandet av varvets lyftkran som löper på räls längs med platån. Betongplatån bärs upp av tre stycken pelarrader och i den östra av de två korridorer som dessa skapar är en fristående byggnad med verkstäder placerad. Den västra av de två korridorerna förblir utomhus men utgör en regnskyddad väg från verkstäderna till skrovhallen och förrådet som är placerade intill betongplatån..

Infringement of intellectual property rights often causes significant economic damage. The problem with illegal activity concerning counterfeiting is constantly increasing. The development has lead to constitute an extensive international activity which is harmful for intellectual propery owners, consumers and the society in general. Competing products tend to be increasingly similar to each other, with rather similar marketing-, sales-, and pricingstrategies. As a result, the trademark strongly affects consumers? selection-process during purchase.

This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.

The remotely operated underwater vehicles that the client develops have needs of different kinds of data channels. In order to minimize the need of physical cable between the control unit and a ROV, a multiplex protocol has been developed. The protocol has been designed with the aim of using the bandwidth of the transferring link as efficient as possible.The different kinds of data channels used during this thesis project is; RS232, RS485 and CAN. ROM and FIFO-memories have been used to be able to effectively manage the different data channels. All the reading and sending of these channels have been implemented in FPGA-technology, the coding is made generic so that it will be easier to add more channels to the system in the future.The multiplex protocol is a modified version of the method STDM and it is a proprietary protocol.

The aim has been to see if physical education (PE) is more an arena for bullying than swedish language education, in a swedish urban school. Furthermore to get an insight in the students sense of exposure to bullying in the locker room and during PE class. In the purpose is also included to analyse the answers in a gender perspective.Questions are: Is PE to wider extent an arena for bullying compared to swedish language education? Is the students? opinion that they feel worried about being and changing clothes in the locker room due to other students bad intentions? Do the students think that boys and girls bully in different ways?The method used is a questionnaire answered by 69 students in seventh and eighth grade in Åsö compulsory school. Furthermore, interviews has been made with a boy, a girl at the school and a teacher in PE to get a deeper insight above the questionnaire.Results of the study showed that the students to a wide extent, 100 % of the girls (g) and 89 % of the boys (b) thought that bullying can look different between PE and swedish language class.

The purpose of this essay has been to answer the question of whether or not administrators of economic support perceive that their professional status is ranked lower than that of their coworkers in other fields of the social services. We set out to study whether or not their comparative status differed depending on their use of standardized assessment instruments and if their experience with regards to professional status differed depending on the size of the municipality they worked in. We also wanted to determine in what way (if any) the comparative status manifests itself and what factors influences it.We?ve utilized method triangulation in order to answer the questions posed in our purpose. The quantitative study was conducted using a questionnaire and the qualitative with three interviews.
