The society of today relies heavily on transportation. Goods and people are transported across the globe at an unprecedented scale and volume and the internal combustion engine is an integral part of the world's transportation systems. Combustion engines emit greenhouse gases that contribute to global warming, one of the most serious global threats today. One of several ways to increase effici
Chemicals are developed and produced in order to meet the desired features of various chemical products. Chemical substances can sometimes cause adverse health or environmental effects when humans and the environment are exposed to them. Landstinget Blekinge (the county council of Blekinge) uses large amounts of chemical products annually. Products such as cleaning products, hygiene products, dent
Scania is a region in southern Sweden that used to be a region of wetlands. Nevertheless, due to human activities wetland loss is an established matter currently, and following from that, changes in biodiversity, water regime and nutrient retention. One purpose of creating new wetlands is to reinstate good status of biodiversity. The study was based on data gathered in July 2011 from 13 newly con
Old trees in cemeteries are often designated trees with "high conservation value" (in Swedish: särskilt skyddsvärda träd), which means that they are important for biodiversity. The Swedish Environmental Protection Agency has created an action plan to conserve those valuable trees in the Swedish culture landscape to preserve, for example, red listed species (often insects, lichens, mosses
The fire-bellied toad (Bombina bombina) is an amphibian that since its national classification as an endangered species in 2005 (NT- Near Threatened) has increased in population size and distribution. Today the population in Sweden is considered viable since 2010 (LC- Least Concern) and it is possible that constructed wetlands in Scania have had positive effects on the fire-bellied toad. The impor
Populärvetenskaplig sammanfattning Genom nedskalning av mikroelektroniken, kan både prestanda, kostnad, och effektförbrukning förbättras och har därmed varit ett mål för elektronikindustrin. Dimensionerna är så låga i nuvarande teknik att parasitisk kapacitans och läckströmmar begränsar möjliga fördelar. Spintronik är en ny teknik under utveckling som skulle kunna erbjuda lösningar för dessa problA new design based on the spinFET proposed by Datta-Das was fabricated, using a channel defined by etching on a 2DEG material and nanomagnets as top-gates. The magnetotransports properties were measured at low temperatures. Magnetoresistance changes with different behaviors were measured in different configurations and the presence of hysteresis showed the action of the nanomagntes. But, due to th
The purpose of this study has been to investigate how social workers, who work with drug abuse treatment in Sarajevo in Bosnia and Herzegovina, experience that organizational, political, economic, societal and power aspects, affect them in their daily work. The study is formed on a basis of qualitative interviews, applying organizational theory as a tool for analysis. The main empirical material
In this report, I investigated possible actions to reduce energy consumption for heating a house in Örnskoldsvik built 1955th. Is it possible to get down to low-energy-rating? Is it reasonable given the costs it entails? The alternatives studied are additional insulation in the basement, wall and the attic, replacement of windows and installation of heat recovery ventilation. After evaluating the
Recent evidence suggests that there are serious information asymmetries in the Kenyan financial market. Between 2006 and 2009, the formal and semi-formal financial sectors in Kenya increased a lot. In contrast to what classic economic theories would predict, the informal financial sector experienced a minor increase. This thesis, through interviews in a minor field study, suggests that the informa
This paper examined and identifies the important determinants of Fertility decline in East Africa countries using a panel data set from world development indicator data base (WDI) for eight selected East African countries between 1998 and 2010. Panel regression methods were used to determine the impact of socioeconomic determinants on fertility. Fertility rate reduced in a slow pace during the per
Syftet med den här uppsatsen är att undersöka hur galenskap, sjukdom och utanförskap tematiseras i Walter Ljungquists roman Paula. Utifrån ett dekonstruktionistiskt perspektiv diskuteras hur texten framstår som galen, sjuk och utanför samt hur galenskap, sjukdom och utanförskap, som tema betraktat, gestaltas i romanen.
Manufacturing firms have a hard time competing with goods only. It is considered that everyone can produce and therefore the competition is solely based on cost. The solution is to increase the value of the offer. Services show great potential in increasing customer value. In addition services are harder to copy and can generate constant stream of income (through contracts). The packaging industry
This thesis examines a number of leaflets and political proclamations distributed in and around Cairos Tahrir Square in the early months of 2011. The theoretical frame work for the study is the claims made by Barbara Johnstone that arabic rhetorics - modern and classical - depend primarily on repetition (lexical coupling, paraphrase, parallelism) when construction an argument, and that this has fa
The aim of this study is to examine how a new area of work is emerging, and how the organization´s framework and guidelines affect the professionals´work. In 2010 a law, concerning the child´s right to be involved when a parent suffer from serious illness, was extended to give these children an enhanced protection. We also want to highlight how the professional´s works are affected of the organiza
Not long ago large cash holding in balance sheet would not be recommended. As we know, large cash in hand means the companies less invest in new projects and extend their business. However, the recent research reveals that U.S companies hold more cash than before, and the financial strength might have strong relationship with the performance. Especially during the financial crises, those who reser
I propositionen till den nya konkurrenslagen som antogs 2008 öppnades möjligheten för individuellt ansvar vid överträdelser av konkurrensrätten. Sedan 2010 riskerar individer som deltar i konkurrensbegränsande samarbete att dömas till näringsförbud. En fråga som lyftes i samband med lagförslaget var huruvida en kriminalisering skulle vara möjlig inom ramen för konkurrensrätten. Frågan har lyfts flThe Bill for the new Competition Act adopted in 2008, in Swedish competition law, opened for the possibility of individual liability for infringements of competition law. Since 2010 individuals participating in a cartel are liable to be sentenced to disqualification from commercial activities under the Disqualification Act of 1986. One issue raised in the context of the Bill was whether criminaliz
Charnockit (hypersten granit), förekommer över hela världen och har beskrivits som en magma-tiskt eller metamorft bildad bergart, ursprunget till charnockiter och definitionen är därför omdiskuterad. Det finns två ytterligheter bland förklaringsmodeller för charnockitbildning, antingen bildas de genom (1) kristallisation av torra magmor eller (2) i metamorfa miljöer vid lågt PH2O. Denna studie omfCharnockite (hypersthene granite), occurs worldwide and has been described as an igneous or meta-morphic rock. The origin of charnockites and the definition of the concept has been widely debated. There are two hypotheses concerning possible formation models for charnockite: (1) crystallization from dry magmas, and (2) low PH2O during metamorphism. This study investigated mineral inclusions, satur
