Variationer av klor, svavel och aska i havrekärna : odlingsfaktorernas inverkan på havrens bränsleegenskaper
The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.
Validitet av observationsbaserade mätningar av armarbetsställningar hos pappersbruksarbetare
Abstract Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 % and not visible 31%.

Rakija eller Absolut Vodka? : Några makedoniska mäns tankar angående sina alkoholvanor och sin alkoholkultur
The aim of this essay was to describe what some Macedonian men had to say about their own and the Swedish alcohol culture and which alcohol culture they identify with.I did five qualitative interviews with Macedonian men that had moved to Sweden. Some of the questions that were asked are whether or not age, country and culture is of importance when it comes to the alcohol culture you have? The most important question to be answered is whether or not the Macedonian men had changed their alcohol consumption after moving to Sweden.The answers to the questions and the result of the essay is that there is no ideal type of alcohol culture but that the Macedonian men all agreed that they still drink as their fellow countrymen and they dislike the Swedish way of drinking..
"Fettpärlan har vi så det räcker till alla!" : En jämförande studie av hur fyra lärare på de studieförberedande och yrkesförberedande programmen tänker och arbetar kring och med litteraturundervisning
On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.
Produktivitet vid stubblyftning :
Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.
Ruminants´production within agroforestry systems in rural Rwanda : production benefits and problems
Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry.
The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein.
The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study.
During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.
Dimensionerande vattenförbrukning och dess variationer
I Sverige användes det år 2010 ca 907 miljoner kubikmeter dricksvatten från kommunala uttag. Allt detta vatten måste kunna transporteras, vilket görs genom vattenledningar. För att dimensionera dessa krävs att man vet hur mycket vatten som skall distribueras och hur det varierar bl.a. beroende på när under dygnet, veckan och året som uttag sker.Vid dagens tillvägagångssätt för dimensionering av vattenledningar till nya områden använder man bland annat typexempel på förbrukningsvariationer under dygnet för ett liknande område. Dessutom används erfarenhetsbaserade värden på maxtim- och maxdygnsfaktorer.Dagens dimensioneringsätt har ej kunnat säkerställas på grund av otillräcklig och bristfälligt detaljerad data över förbrukningsmängd.
Produktivitet och lönsamhet vid skogsbränsleuttag i klena gallringar : en tidsstudie av Vimek 608 BioCombi i contortabestånd
The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of Västerbotten.
En ödmjukt auktoritär rådgivning : Ethos och etik hos föräldrarådgivaren Petra Krantz Lindgren
Wermland was affected by the Spanish flu like the Swedish national average, about a half percentage of Wermlands population would lose their lives to the flu during the autumn 1918. The flu has for many fallen into oblivion. This oblivion is so wide spread that it´s possible to talk about a "collective forgetfulness". The society have selected to remember 1918 for "when the guns went quiet on the western front" and not for the millions who died from the treacherous Spanish flu. The world had already suffered enough from the four years of war that had been fought, thus the victims of the flu would be honored but would soon fade in to oblivion. When you investigate deeper you get the picture that the national average don´t do Wermland and its cities or rural areas any justice when a large variations seems to occur within regional areas.
ATT VARA ÖPPEN FÖR OLIKHETER I TIDER AV FÖRÄNDRING : Barnmorskors och BVC-sjuksköterskors erfarenheter av föräldrars behov av tidigt föräldrastöd
Society has an obligation to offer parents support of various types, an example of such a support is ?parent support?. The purpose of this study has been to describe midwives and child health care nurses conceptions of the need for early parent support. The definition of early parent support in this study is the first two weeks after delivery. Since the 1970:ies the Swedish delivery and ?BB? care has changed in that the time in hospital care after delivery has been reduced from in average six days, till an average of two days.
Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon
Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques.
The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.
Vad är verklig kostnad per koplats? :
Purpose
There are almost infinite numbers of ways to build dairy farms in Sweden. When building a new free stall barn you have the possibility to affect both working environment and animal welfare for many years to come. The construction costs are influenced by which type of barn that is built and what functions it contains, for example one can predict that automatic milking systems are more expensive to integrate than milking parlours. But what is the real cost of today for the construction of free stall barns with milking centres and how is it affected by construction methods and functions? Is the labour time influenced by the building costs? These are some of the questions this report will try to answer.
Kommunernas dolda pensionsskuld
Background: In 1998 it was stated that Swedish municipalities would report the pension liabilities according to the mixed model where the pension liabilities before 1998 was moved from the balance sheet. The mixed model has been criticized by economists for not showing the total pension liabilities. To remove some of the liabilities in the municipalities balance sheets means that the solvency improves. Some municipalities have decided to go against the municipal accounting law and recognize all of the pension liability as a liability according to the full funding model. When two accounting models are being used the comparison of the municipalities' financial statements is much harder.Purpose: The main purpose of this study was to study the reason why some municipalities apply full funding model rather than the mixed model.
Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser
Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.
