The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.

Sammanfattning Titel: Lågkonjunktur ? En studie i vilka skillnader som finns för variationen i antal anställda inom IT- respektive industribranschen Författare: Emilio Nilsson, Oscar Kacprzak Handledare: Emil Numminen Institution: Blekinge Tekniska Högskola Kurs: Kandidatarbete i Företagsekonomi Syfte: Syftet med uppsatsen är att undersöka och analysera för hur företagets ekonomiska data för den relativt unga IT-sektorn förklarar antal anställda gentemot hur företagets ekonomiska data förklarar nyckeltalet för en äldre mer erfaren bransch som industrisektorn. Metod: Vi har samlat ihop kvartalsrapporter från 1999 års första kvartal till 2009 års första kvartal för totalt 10 stycken företag som vi bedömt lämpliga för studien, 5 företag från IT-branschen samt 5 företag från industribranschen. Vi har därefter fört regressionsanalyser med antal anställda som Y-variabel och totala intäkter, aktienivå, rörelsekostnader samt rörelseresultat som X-variabler för att finna korrelationen däremellan. Slutsats: De framkomna resultaten från regressionsanalyserna pekar på att det finns skillnader branscherna emellan.

The purpose of this study is to examine how the work with young people at home to care and accommodation (HVB) are organized in a municipality outside Karlstad and how the staff perceive emotions in the workplace. The issues that are discussed are based on the concepts of social ties, emotional labor, roles, shame and pride. The number of people who are fleeing in the world is today about 51 million. There has not been this high since World War II. The Swedish Migration Board calculated that about 7,000 of these people were unaccompanied children and came to Sweden in 2014.

After parturition the energy demand for milk production is greater then the energy provided from the diet. The cow mobilises therefore body tissues to compensate for the energy loss. Live weight and body condition scores decreases as a consequence of the mobilisation. The aim of this study was to analyse the relationship between body condition score, live weight and subcutaneous fat depth measured by ultrasound and the changes during the lactation. Possible differences between Swedish Holstein (SLB) and Swedish Red and White Cattle (SRB) were also investigated.

The main purpose of this analytic study which has a theoretical focus, Is to find out if the two Swedish parties Socialdemokraterna (s) - The Social Democrats - and Folkpartiet (p) - The Liberal Party - has taken position ideologically or strategically to the new sex-degree grading scale. The theory section describes the concepts of ideology and strategy. Despite the talk of the death of the ideologies, this don't need to be the case, they only adjust över time. The second key-point of this essay is strategy, a model based on Frostbergs reasoning illustrates this. A number of problem areas are presented.

This study?s purpose is to identify and analyse the risk associated with outsourcing of services within real estate management. Completing this study I have used the method induction with qualitative personal interviews. A number of risks are identified, however, the advantages of outsourcing generally dominate over disadvantages. The companies studied are generally able to handle the risks associated with outsourcing..

In this essay I analyze the performative aspects relating to Marina Abramovi?'s The Artist Is Present, which took place in spring 2010 at MoMA in New York, from the context of the artist and work, institution and documentation. In this performance work, for the duration of the exhibition, Abramovi? sits completely still opposite another chair where anyone from the audience may sit. The art arises through this participation.

Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

ABSTRACTIntroduction: Preoperative hand disinfection aims to prevent surgical site infections. After the preparing hand wash, drying is performed using an aseptic technique. It?s important to dry hands thoroughly in order to achieve the full effect of the alcohol based hand disinfection. Due to the lack of a evidence-based guideline on this procedure, the hand drying techniques differ among operating theatre nurses, depending on which technique seen as the most appropriate.

This thesis describes the planning and development of a volume meter of pine and spruce cones. The product was designed and developed for Stigsjö Skog och Frö AB in Härnösand. It was developed taking into account a number of requirements set by the supervisor David Zetterlund. The main requirements were that the volume measurement would be fast and give accurate results. These are two requirements that are missing in today's volume measuring method which is very problematic for the company.The plant was visited several times in Härnösand, mainly to discuss the generated concepts with the supervisor and perform tests on the prototype.

In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

This master thesis was performed at Scania Research & Development. The given mission was to see where the department Systems Development should focus to improve their development work. Thus the purpose was to map the product development processes in which the department works today and within them identify improvements. To fulfil the purpose a theoretical study of relevant terms, such as improvement work, product development and processes, initially was formed. The mapping method used is called "walk trough" and meant to let the people working in the processes be guides in their own process.

Library and information science (LIS), being a research area characterized by theoretical discord and definition disarray, provides an interesting field of inquiry. Its content, boundaries, scope and superior identity are not clearly stated. This Master s thesis focuses on a thus far unexplored perspective on the discipline: a conceivable statistic and causes- and- effect relationship between the LIS students appreciated identification with the superior identity of the discipline, and the chosen vocational direction within the field. This relationship is examined through testing a working hypothesis on the results of a major quantitative questionnaire survey. The theory behind our research derives mainly from Thomas Kuhn and Richard Whitley.
