Flickor, brott och våld : en pilotstudie om flickors ökade brutalitet i samhället.

AbstractThe main objective of this essay is to come to an understanding as to why girls, together in groups, walk against the conventional image of women and take on more violent and aggressive behaviour against their surroundings. In this essay I hope to gain an understanding of how ?girl gangs? work as a social phenomenon as well as identify the characteristics of these gangs. Furthermore, this essay aims to understand what role the violence and aggression plays in the lives of these girl?s.The following questions are the focus of the essay:? Why have girls in groups become more aggressive and violent?? What is characteristic for ?the girl gangs? as a social phenomenon?? What role does the girls? aggressive behaviour play in their life?The essay touches on an escalating problem within society, which has received considerable attention in the media lately.

Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Gerillamarknadsföring -Konsten att sprida ett budskap med knappa resurser

I genomsnitt utsätts vi för 3000 reklambudskap under en dag, men bara cirka 14 % av de okonventionella kampanjerna har någon effekt. Vi har blivit för medvetna om hur reklam påverkar oss och för kritiska mot media för att köpa dessa budskap. Jay Conrad Levinsons grundade för cirka 30 år sedan begreppet gerilla marknadsföring. Den här kreativa marknadsföringsmetoden var till en början tänkt för de företag som hade begränsade resurser. Metoden kan vara väldigt kostnadseffektiv och används idag flitigt bland både stora som små företag.

Räntefritt sparande : en kvalitativ studie som berör svenska bankers förhållningssätt till räntefritt sparande

Efterfrågan på räntefria banktjänster har ökat i Sverige, vilket främst beror på den utvecklande invandringen som efterföljer religiösa principer i sitt vardagsliv. Detta har vidare resulterat i att allt fler individer i det svenska samhället väljer att avstå från stora lån samt sparande då det strider mot deras religion. Individer som således är i behov utav kapital, vänder sig istället till vänner samt släktingar för att exempelvis kunna ha möjlighet till att köpa en bostad.En av de mest väsentliga faktorerna till varför konventionella banker inte utvecklar räntefria sparalternativ är på grund av reglering samt lagstiftning. Historiskt sett har det traditionella systemet i bankerna funnits under en väldigt lång tid, vilket resulterar i en effektiv reglerings- samt tillsynsorgan. Bankerna anser även att en utveckling av räntefritt sparande kräver en efterfrågan som är större än vad den är i dagsläget.Syftet med denna uppsats är att undersöka hur konventionella banker förhåller sig till räntefritt sparande samt hur den yttre omgivningen, exempelvis andra banker samt finansiella aktörer, påverkar banken.

Liquid diesel biofuel production in Sweden : a study of producers using forestry- or agricultural sector feedstock

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Inhysningssystem för kalvar och ungdjur i större besättningar :

In Sweden, there has been a continuous increase in the volume of housing construction for dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.

Rätt gåva för rätt tillfälle

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Örter som fodertillskott till häst : populärt komplement utan risker?

In the Swedish market, there is a wide selection of herbs as supplement to the horse´s feed. A trend today is that many companies are marketing herbal remedies with allegations of medical effects. If you want to sell the product for that purpose it must be verified and approved as drug or natural remedy by the Medical Products Agency. Some herbs may contain active substances. Nevertheless, only a few studies have been conducted on single herbs to investigate safe doses for horses.

Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?

Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water. The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting). The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture. Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied with 0.8 L per week.

Welfare impairment of lambs around weaning. Play and other behaviour indicative of affective state

The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.

Förändras mjölkens proteinsammansättning i separata juverdelar i samband med höga celltal (SCC)? :

Today the milk production per cow is increasing but the milk delivered by the Swedish farmer contains less amounts of fat and protein than earlier. The contents have decreased since 1993. In average the milk contain 4,2 percent fat and 3,4 percent protein. Earlier the fat content in milk was important. Nowadays the dairy?s attention has turned to the milk?s valuable proteins, principally the caseins, which have a considerable nutritional value and are important for several dairy products like cheese and yoghurt.

Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?

Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.

Barnmorskans handläggning av alkoholinformation under graviditet.

Bakgrund: Enligt Statens Folkhälsoinstitut, i barnmorskors guide för samtal om alkohol, redogörs för hur barnmorskor skall informera alkoholens skadliga effekter samt vilka eventuella skador alkoholen kan ge fostret. Tidigare forskning visar att det inte är ovanligt att kvinnor dricker alkohol fram tills att de blir medvetna om sin graviditet, därefter avstår det stora flertalet helt från alkohol under fortsatt graviditet. Vetskapen för den gravida kvinnan om att hon intagit alkohol innan hon var medveten om sin graviditet kan orsaka oro att barnet blivit skadat. Syfte: Syfte med studien var att beskriva barnmorskors professionella handläggning kring alkoholinformation under graviditet. Metod: Studien bygger på fem semistrukturerade intervjuer med barnmorskor som arbetar inom mödravården.
