The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

An overwhelming majority of all male piglets are castrated without anaesthesia when they are very young. In Sweden this means that approximately one and a half million piglets are castrated every year. The reason the piglets are castrated is the strong and unpleasant smell and taste, the ?boar taint? that the meat from intact boars sometimes exhibits. Boar taint is chiefly cause by androstenone and skatole, two compounds that are mostly produced by sexually mature boars and are accumulated in the subcutaneous fat.

Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.

Background: Overweight in children is a growing problem around the world. Studies has shown that children suffering from overweight, are at a greater risk to remain overweight as adults as well.

Within the union barriers for trade has been abolished in order to create more open market. This open market has also contributed towards a more globalized market for dairy products. What used to be a domestic market has become globalised with increasing trade among the members.

Maternal behaviour is crucial for the development of the rat pups? behaviour and stressresponses later in life. There are numerous studies evaluating the effects of the dams?behaviours on the pups, but not many addressing what can be made for wellbeing of the ratdams when breeding. Few studies have addressed the question of how the commonly usedrearing environment effects the dams? behaviour and in the long run how it effect the ratsreared to become our research models.

Training of zoo animals started when the first zoo opened in 1752. The difference between then and now is that from the beginning the zookeepers did not focus so much on animal welfare. Nowadays animal welfare is the most important thing in the training. Therefore, the zookeepers are training the animals mainly for veterinary purposes and activation. The training makes the animals less stresses during handling. When the zookeepers started to train elephants they used unpleasant stimuli such as a whip when the elephant did something wrong.

Empati är att kunna uppleva och förstå andra människors känslor. Tre studier gjordes för att undersöka socialsekreterares empati för sina klienter och hur de upplever sin professionella och genuina empati. Två studier var kvantitativa och en var en mixed design. Deltagarna var 26 socialsekreterare och 57 socionomstudenter. Studie 1 och 2 visade att socialsekreterare och studenter på socionomprogrammet hade mer empati för en sympatisk person än för en osympatisk.

The discrepancy in the rights for healthcare between undocumented migrants and the citizen in Sweden is a prerequisite for the existence of Läkarkliniken. Because of the chosen patient group the clinic stands outside the regulations from the National Board of Health and Welfare. The aim of this study was, from an institutional perspective, to investigate how such a unique player is designed and where the influences to the design origin from. The task was conducted thorough a qualitative case study with base in depth interviews. High levels of isomorphism were observed between Läkarkliniken and the general healthcare, however differences were seen as well.

This study focuses on the influence a user may have over his or her welfare service, personal assistance.

Questions regarding influence of the user when she or he is choosing the assistance provider and the users possibility to influence and his or her power to decide who and when anyone works as an assistant are asked..

This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.

Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.

?Entity continuity? refers to recurrent transcendent experiences related to certain places (?hauntings?). The experiences are often interpreted to be due to discarnate spirits or folklore entities. Although the entity continuity experience can be regarded as religious experience, they have yet to be fully explored in science of religion.The purpose of this paper was to describe entity continuity experiences and map out the scientific discussion in order to provide a psychology of religion that provides an understanding of the phenomena. For this purpose a literature study of theories of jungian psychology, parapsychology, and described experiences was undertaken.

This essay discusses how insurance companies inform policyholders regarding home insurance. What level of support do insurance companies offer policyholders in order to supply them with enough knowledge to make an informed decision? Is information regarding insurance communicated in simple terms, or is it riddled with industry specific terminology?The essays focus is important to examine from a social context; Swedish social process does not select an insurer for an individual who neglects to choose one for their home insurance. Sweden's welfare system does otherwise provide a helping hand for a lack of decision with regard to preschool and school choice..

The Iranian artist Shirin Neshat has been living in self-imposed exile since the late 1970s, as she chose not to return to her home country following the ?79 Islamic Revolution. Through her works Neshat examines Iran before and after the revolution and follows political and civil transformations through strong photographs of women in her country of birth.  My own use of the term exile deals with the analysis of the state of exile in relation to artistic work as a globalized and underlying motivation for art and artists. The new definition of exile is analyzed in relation with the artist?s photographs and the verbal and visual statements.
