Today evidence exist that environmental chemicals deteriorate male sperm quality and that testicular cancer is increasing. Bisphenol A (BPA) is a chemical with estrogenic effects used in the manufacture of polycarbonate plastic and are found in, for instance, plastic boxes, feeding bottles and food containers. Much of the research on how men's reproductive ability is influenced are performed on rats. This review article complies how male rat reproduction is affected by BPA as a model for humans. Studies have investigated how sperm are affected, hormonal changes during reproduction and how reactive oxygen species (ROS) affects sperm.

The purpose of this project is to examine students' pespectives on quality in teaching. The characteristics that are described to denote a 'good' and 'less good' teachers are linked to ideas about types of corresponding leadership styles in the classroom. The report is based on surveys of students in Upplands-Bro high school outside Stockholm. In order to get better insight and further knowledge of the subject, the student accounts have been related to current discussions in the literature about good leadership and teaching quality.Following the methodology of grounded theory a pilot study was constructed to design the research instruments. In the pilot study I collected students' perceptions on quality-related categories in teaching and leadership which then formed a bases for a survey which was distributed to a larger student sample. The survey includes questions that relate to the middle order, which is based on three criteria that make up the characteristics of a 'good'/ 'less good' teacher and the leadership style that suits students descriptions of good teacher characteristics.The results of the study show that a good teacher should have subject knowledge, be good at writing and illustrating the curriculum on the whiteboard and explain and clarify their instruction through good communication.

Focus of this study was on the underlying values behind consumers buying motives at the point of purchase of meat products in Sweden. Meat consumption in Sweden has increased and in 2012, almost 50% of all meat consumed was imported (SJV, 2013). This is the case despite of the fact that consumers frequently state the importance of Swedish country of origin on the meat products they purchase (www, LRF, 2, 2006). A rising public awareness about health, environmental issues, animal welfare and food safety coupled to meat consumption and meat production is scrutinized both from media and consumers. Due to rising concerns of production-methods of meat, consumers wants to make informed purchasing decisions of the meat they purchase (BEUC, 2013).

Jällaskolans upper secondary School is situated on a big farm just outside Uppsala. The School is focused on agriculture, forestry, gardening, animal care and science. Jällaskolans staff has whished for a school garden for educational purpose where students can practice their gardening skills and learn more about plants. But most important, a specially adapted outside environment such as a garden, would be a great advantage for the students with special needs. This garden could even be an asset for other visiting school classes in the region.

Positionsbestämning med hjälp av satelliter kan idag göras med olika metoder. En metod som i realtid ger en mätosäkerhet på centimeternivå heter nätverks-RTK. Det som gör att nätverks-RTK ger en låg mätosäkerhet är att de felkällor som påverkar GNSS-mätning reduceras eller elimineras med hjälp av en interpolerad korrektionsmodell vid mottagarens position. Korrektionsmodellen skapas med hjälp av data från de fasta referensstationer som finns i närheten av GNSS-mottagaren. SWEPOS® är ett nät av referensstationer som finns i hela Sverige och erbjuder en nätverks-RTK-tjänst där det kan förväntas en mätosäkerhet på omkring 15 mm (1s) i plan och omkring 25 mm (1s) i höjd (över ellipsoiden).

The purpose of this study is to analyse how a distribution and sale-network for quality softwood lumber should be designed to fit sawmilling companies? business concepts, and at the same time satisfy customer needs regarding delivery time and quality aspects. This thesis work is a case study based on a sawmilling and retail company in Sweden. AB Karl Hedin is a private owned sawmilling company with 500 employees. The company?s turnover is 1500 million SEK, it includes 4 sawmills, 16 builders merchants stores and a packaging company.

The aim of this study is to investigate ordinary readers' evaluation of quality in literature. The main issue is which criteria ordinary grown-up readers use when they are defining their likes and dislikes in literature. The analysis is based upon qualitative interviews with six readers, two men and four women, between 21 and 59 years of age. The study is hermeneutic. Since theoretical works concerning evaluation of literature among ordinary readers are sparse, the philosopher of arts and religion Hugo A.

This is a final thesis on the landscape architecture program at the Swedish University of Agricultural Sciences. It is the end of five years of studies and comprises 30 ECTS. This thesis is about the camp area Sjöröd, located by Gyllebosjön (the Gyllebo Lake) on Österlen in Skåne, southern Sweden. The thesis results in plan for how the area could be used in the future. It also raises the questions; what scouting of today is, how it is to be developed for the future, what a camp is and which aims the scout movement has set up for itself and its activities. The thesis also treats what is typical for Skåne, for Österlen and for the area around Sjöröd as a starting point.

The intention of this study is to interview teachers in order to create a picture of how they look at their work with IUP (Plan of individual development). The main question formulated in my study is in what way IUP can become a contribution to the learner´s development. All teachers who participated in the interviews believe that the purpose of the document is to be proactive, developing and positive for the pupils. The teachers also believe that it is intended to serve as a clarification for pupils as well as teachers. It´s clear to see that the IUP generally is believed to be a supportive resource in education.

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

The executives of a firm possess considerable influence over a company's financial reports.

Syftet är även att visa vilka erfarenheter som dragits av studier om implementering av resolution 1325 och hur Regeringens plan och Försvarsmaktens arbete stämmer överens med de dragna erfarenheterna.

The purpose of this study was to investigate how social workers who worked with financial assistance perceived their work situation and the impact work-related stress had on their health and quality of work. Further, the study intended to find out if they felt that they received support from their employer that could prevent stress-related sick leave. The following two research questions were to be answered: In what way does work-related stress affect social workers? health and job quality according to their own experience? What kind of support and help experienced social workers were available within their organization? To receive answers to the questions semi-structured interviews with five social workers were conducted, analyzed and interpreted. The results showed that when social workers have a heavy case burden, high stress and a risk of deteriorated job quality occurred.
