I am a practising classical soprano. After more than 20 years of professional singing, I re-trained my voice according to principles of the old Italian school of singing. In this essay, I examine the origins and priciples of bel canto, with special focus on appoggio and chiaroscuro, two key ingredients in the bel cantao tradition. I explore the relationship between science and the craft of singing, and what modern voice science has to say about the efficiency and health aspects of this technique, I also describe the profound effect it has had on me as an artist..

I transportbranschen finns behov av ett gemensamt och standardiserat mått för mätning av effektivitet och trots avancerade IT-system och moderna verktyg råder det idag avsaknad av detta. Transportföretagen behöver inte bara ta fram egna, interna mått utan också accepterade och vedertagna mått som kan användas för att kommunicera med kunder, myndigheter och andra externa intressenter..

Through the growing use and availability of information technology the dependency of Internet is today increasing. Internet makes ways for a more mobile business communication that cost less. One of the latest applications of Internet technology are intranet and extranet. I have asked myself the question how intranet and extranet can affect companies efficiency and competitive advantage. In order to answer this question I performed a case study at Ericsson and ABB.

In this essay I?m asking if the Scandinavian countries Sweden, Denmark and Norway use a third world perspective on gender equality in their development aid politics. A third world perspective on gender equality is a perspective that considers the special experiences and priorities of women in the third world. My point of view is that third world perspectives represent women in the third world better than western perspectives.To determine if the countries uses a third world perspective on gender equality or not I have examined the countries aid policies with a third world theory. The material that I have used is policy documents on gender equality from the three countries and my method is discourse analysis.My study shows that Sweden Denmark and Norway uses a third world perspective on gender equality to a certain extent.

An increasing number of automotive supplier companies are investing in Central and Eastern Europe (CEE) in order to gain cost advantages. This has happened in a rapid pace since many of these countries did not have any foreign direct investments (FDI) at the turn of the century. The problem now is for how long these countries will be able to maintain the low costs. One purpose was to create a model of country advantages for automotive supplier companies when relocating further production to CEE. This dissertation was written in cooperation with the Trelleborg Group.

Fighting against accidents with elderly involved have come to be one of the west world's greatest challenges together with the climate changes and epidemics, and in order to fight against these accidents SDF Centre, Gothenburg appointed a man to the post as a caretaker.The aim of this master thesis is to analyse whether the implementation process and the systematic work correspond with Vedungs implementation theory and also put forward arguments for and against a masculine entrance into promotion old-age care; if it strengthens or is a take-off from the classical sexual roles.The thesis main theory is Evert Vedungs theory of implementation, which is constituted of eight factors which facilitates an implementation process. In order to theorise the sexual roles I have appropriated a gender perspective, constituted of multiple researchers and authors.The conclusion I have received through the qualitative interviews carried out with actors involved in the implementation process, is that the security services implementation correspond well with Vedungs implementation theory, hence the implementation has proceeded efficiently. The classical sexual roles is on one hand strengthened through a masculine possession of the security service, and on the other hand can the masculine entrance in the old-age care entail that more men apply for promotion old-age care work..

This Mag. thesis discusses how a gender perspective could be implemented in themanagement of cultural heritage focusing on the built environments in Sweden.The thesis further argues for the need of a gender perspective on the conservationof cultural heritage.The two main approaches, additive through the perspective of the women?s part inhistory and integrated gender perspective, are thoroughly presented in the thesis.In the additive gender approach built objects that represent women?s experiencesand lives are added to a history that traditionally represents men and theirexperiences. The integrated gender perspective includes a gender in all activitiesas an instrument in a historic analysis. The gender perspective illustrates therelation between the sexes.

Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

The aim of this paper is to investigate to what degree the groups in our inquiry work independently. It is a qualitative research, which points to a well?functioning unit, that by definition is not self-governing, but has many traits of self- government. We have reached to the conclusion, that complete self?government does not have to be the best solution, if you want both quality and efficiency.

The use of thin and attractive models to promote companies' products is widespread among marketers. This is true even for companies whose products have little or no association with beauty or body weight. As the proportion of overweight people continues to grow in many developed countries the ideals used by marketers to attract customers strays further away from the actual attributes of the customers themselves. What is little understood is what effect overweight has on the efficiency of the product promoter. Some limited research has studied how the efficiency of the product promoters in printed advertisements is affected by the existence of congruence between the product promoter and the product itself.

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Barnamordsplakatet (a Infanticide Proclamation) of 1778 was a circular allowing unmarried mothers to give birth at an undisclosed location without giving up the name of the father. The proclamation was supposed to ease the situation for the unwed mother in Sweden.The aim was to investigate whether women in Assembly of Hällefors, far from government and close to remote forest Finnskogen, was affected by the Infanticide Proclamation, between 1771 and 1830.Case studies has been done on people who had illegitimate children, if they were convicted, what the crime was and what the punishment was. The investigation is made at a local level and compared against national analyzes on the same theme.A lot of illegitimate children were born in Grythyttan nearby and slightly less in Hällefors, compared to other places of Sweden. Mothers and fathers were convicted in the district court for crimes, including, sexual intercourse between unmarried persons. More women than men were convicted.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Efficiency has become an important objective for many providers of welfare services. Among Swedish schools, both private and public, increased administrative demands seemingly influence operations, and affect teachers negatively through perceived stress. Simultaneously, Swedish students scored an all-time low in the latest PISA survey, and are now performing below the OECD-average in science, mathematics and reading. A central administrative task in the Swedish elementary school is the parent-teacher conference, which is an important activity in supporting the development of the student's knowledge and social skills. Lean is a well-established operations framework, which has proven successful in order to improve process efficiency.

Abstract The aim of this study was to explore and describe the pupils' thoughts on seed and its development into seedling. Twenty nine Swedish pupils at the age of 7 and 10 years old were interviewed about their knowledge of seeds.It turned out that pupils often have so-called everyday belief to describe the natural science phenomenon by connecting their explanations to phenomena in everyday life to which they are familiar. To describe the process of seed developing into seedling is something that most of the pupils believe to be difficult and this resulted mostly in the answer ?it is growing.? Children have some knowledge about what seeds need in order to germinate but they do not mention the importance of oxygen as a component of seed to be able to germinate and grow. They mean instead that it is sufficient with soil, water and sun.The older pupils, however, are more often than the younger pupils able to connect their reflections to a more scientifically correct description based on terms belonging to the phenomena, though these terms sometimes are wrongly used.
