Vaktelproduktion för ägg och kött
The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production. Globally the quail production is very small, except in China where it is the second largest poultry industry. The production globally is small despite the quail's rapid growth, early sexual maturity and its high feed efficiency. The quail is also used as a laboratory animal and can be reared to be released in hunting areas.
Effektmätning i pump
The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.
Varför stannar en kvinna hos en man som slår? : Forskning kring mäns våld mot kvinnor i nära relationer
This study has a qualitative approach and deals with difficult issues that arise in connection to male violence against women in close relations. The purpose of this study is to bring clarity to why women stay in violent relationships. I have been studying two leading theories, one called the Normalization Process of Violence represented by Eva Lundgren (sociology and theology). The other leading theory is the Neutralization of Violence represented by Margareta Hydén (fil dr and leg psycho therapeut).I have also studied the fight between these two theories for the leading position in the research on male violence against women. Eva Lundgren presents her theory through a structural perspective.
Utvärdering av substrat för biogasproduktion
The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..
Nätverk och makt - En fråga om makt och relation mellan politiker och tjänstemän
I have studied how network in a broad sense can affect decision-making. The primary purpose is to see if the political initiative somewhere disappears when it comes to understand the relations between power, actors and politics. The study discuss in a theoretical area that concerns the reliability in neoinstitutionalism to use as an analytical instrument. Some criticism is given to the theoretical standpoint in the sense that there is no power perspective included in the theory. I include a discussion about a concept of power, which I include to the theory.
Opera i Stockholm : Stadsgårdskajen
The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..
Ett re(el)lt hot? Om elprisets betydelse för investeringar inom basindustrin
The aim of this thesis is to investigate the correlation between the price of electric power and investments within the Swedish basic industry. Using regression analysis, the authors test for correlation between the electricity prices and the basic industry, defined as the pulp and paper industry, the mining industry, the steel and metal industry and the basic chemical industry. Moreover, five variables found in the literature on investment decisions are being used as a means of comparison. The results suggest that the electricity price affects the investment decisions within the basic chemical industry as well as the steel and metal industry. On a more abstract level, this thesis contributes to the understanding of one of the properties of the Swedish GDP..
EU som normativ makt i Vitryssland - ett kritiskt fall
ABSTRACTThe EU as a normative power in Belarus ? a critical caseBy Anna JohnssonUniversity of VäxjöSchool of Social SciencesSpring semester 2007The European Union?s identity is a much debated topic. Some say it?s a unique actor in the international arena because of the different tools it has at its disposal. Ian Manners claims that the EU is what he calls a normative power.
Papperslöst motstånd : Om strategier och praktiker i post-välfärdens marginaler
The post-modern western city is going through two central changes in the organization of paid labour. One is the switch from production of goods to production of services, and the other is the increasing rift between well-paid labour with permanent jobs, and temporarily employed workers with low wages. Both of these processes are rasified and gendered, and strike harder against women, young persons and people of emigrant background. The flexible capitalism creates an informalization of the economy, breaking with earlier regulations of the labour markets, in which workers also need to find informal strategies in their individual and collective struggles. In this paper, I search for these ?new? experiences of living and working in late capitalist society, by doing open interviews with three women of Latin-American origin, working without official permission (without documents) in the informal economy of Stockholm.
Ståndortsanpassning och produktionspotential för björk i Gävleborgs län
Large amounts of birch-timber are imported to Sweden, from particularly the Baltic States, since the domestic production can?t support the pulp industry. The goal of this study was to show the potential of birch and the area?s most suitable for birch production. The study was limited to Gävleborg County.
Using site characteristics, site index (SI) for birch was estimated on all National Forest Inventory plots in Gävleborg County.
Optimering av SNCR-system i en biobränsleeldad panna : möjligheter till minskade NOx-utsläpp för ENA Energi
Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.
Det manliga köttet: Om köttets roll i skapandet av maskuliniteter, och den svenska hållbarhetsdiskursens genus(o)medvetenhet rörande ekologiskt hållbar köttkonsumtion
Several studies indicate that Swedish men consume more meat than women, more frequently appear in advertisements for meat and more often than women handle the grilling of meat. Production of meat is one of the largest contributors to greenhouse-gas emissions and thereby poses a challenge for ecological sustainability. Several Swedish politicians and authorities have argued that reduced meat consumption is necessary to prevent continued global climate change. To understand and change consumption patterns we need to understand the consumer. This essay uses textual analysis to examine how Swedish men through text and images in three cookbooks use preparation and consumption of meat to construct different masculinities.
Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet
Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.
Frekvensreglering i det nordiska kraftsystemet
Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
Hur mår svensk filmmusik? : En kvalitativ studie av svenska filmkomposito?rers fo?rutsa?ttningar i det nutida produktionsklimatet
This thesis examines Swedish composers' modes of work and production within the Swedish film industry. It starts off with a historical overview treating live music in early silent film, the conversion to sound and the Swedish production climate until present time. The analysis consists of contemporary empirical studies; interviews with people writing music for film, TV and commercials. The musician's perspective is in focus but directors and other film workers are heard as well. The situation for female composers in a male-dominated industry is also discussed.
