Soapnuts have been used as a cleaning detergent and medicine since ancient times in different parts of Asia. Today soapnuts are sold as an environmentally friendly alternative to common washing detergents. The aim of this literary study is to give an answer to what it is in the soapnuts that makes them work as a washing detergent. The active component belongs to a group of components called saponins which are secondary metabolites with the purpose to protect the tree from pathogen attacks. Saponins are widely spread in the vegetable kingdom and some of the families and species are so rich in saponins that their names are influenced by this, for example Sapnindaceae and Sapindus which are mentioned in the beginning of this literary study.

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

The Public Sector Scorecard (PSS) is a younger version of the balanced scorecard, created for public and nonprofit organizations. The latest model of PSS is divided into three main groups and seven perspectives, while the balanced scorecard consists of four perspectives. Organizations who use either PSS or the balanced scorecard are supposed to have a clear vision spread all over the unit. This study has sought differences between the two models of financial control in both theory and practice. The first part of the study is a theoretical comparison between the models? structures and terms used in them.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

AbstractThe purpose of this thesis is to highlight the organization's importance to teachers' working environment. Through a survey conducted at a primary school in New Zealand and at a primary school in Sweden, teacher perceptions of their psychosocial work environment were compared. This study has answered the questions: ?How does a teacher at a school in New Zealand and at a school in Sweden view their psychosocial work environment from an organizational perspective?? and ?What are the similarities and differences in psychosocial working environment between a school in New Zealand and a school in Sweden?? The results were analyzed based on Karasek and Theorells demands-control-social support model. The study shows that teachers at both schools are experiencing high demands, but that New Zealand teachers are experiencing greater demands.

The aim of this study has been to achieve an increased understanding of the meaning of home for people in homelessness. The study is based on texts written by people in homelessness and a qualitative content analysis has been used to process the material. The result has been analysed with an inductive approach, using parts of the analysis method grounded theory. Three aspects of the meaning of home was identified in the texts; control, self-determination and independence. The lack of a home means a major limitation concerning these aspects, according to the texts.

The purpose of this thesis is to explore the situation for ebooksin Swedish public libraries. The background is anincreasing lending of e-books in public libraries, with anacquisition model formed when e-books were more of anexperiment in a few libraries. The debate has escalated in therecent years and in this thesis I aim to investigate thelibraries? experience with e-books and the current pricemodel. The empirical material comes from interviews witheight head of public libraries in the Västra Götaland region.As theoretical background, I have used Michael Buckland?sfour roles of collections and price models from Lee andBoyle.My results show ambivalence with the price model.

The purpose of this thesis is to study the personal problems that can occur when defecting from a destructive cult, and what kind of support you may need from social authorities. The aim is to develop guidelines for social workers who are in contact with sect defectors. It?s a qualitative study based on interviews with six defectors from Jehovah?s witnesses. The results shows that all the defectors that have been interviewed have had anxiety problems, lost contact with friends and relatives, low level of education, and low self esteem when defecting or after.

Skiascopy is used to objectively determine the refractive power of the eye. Except for a Swedish study in 2007, where 93 horses of different breeds and ages were examined with respect to their refractive status, most studies on equine refraction were published about one century ago or more. The objective of this study is to examine the refractive status of healthy warm-blooded trotting horses. Skiascopy was performed in 117 horses in total, aged 3 days to approximately 22 years old. In a pilot study, it was determined whether young horses were able to accommodate or not during skiascopy. The horses in the pilot study were all younger than 14 months. In foals younger than 1,5 months we saw a significant difference in the skiascopy result in the right eyes before and after topical atropine was instilled, but not in the left eye.
