Elektrolytisk reduktion av zink vid reningsprocess
When cylinders for motor saws are manufactured there are high demands on the cylinders strength and wearing qualities. Aluminum is a material with low density and is used by Husqvarna AB for their motor saw cylinders. The aluminum is strengthening with nickel that is attached to the cylinders through electrolysis. When aluminum is in contact with oxygen a film of oxide is formed. To eliminate the oxide and to prevent formation of new oxide zinc is used.

Känsla kontra information i fotokommunikation
Photography has a big role in information sharing today. Especially in the hotel industry where it is the closest thing a customer can get to the product that is being sold. This study intends to find out how you can make use of rhetorical models and techniques of photography to enhance the communication skills of photos of hotel rooms. The main focus was to understand the difference between informative and emotional photographs and what consumers themselves focus on when choosing a hotel, and also how to use the collected information to create a larger buying interest through hotel photography. Using previous research work and quantitative data collection method, we have concluded that the informational and emotional photography methods have obvious differences but also many similarities, and are most effective used together and that the hotel consumer is more aware of the images influence then we assumed..
Två metoder av finutsättning och dess noggrannheter
This report describes a study of two different methods to achive the best possible result in setting out apartment details. These two methods are the setting out of details with a measuring tape from baselines and the setting out procedure with an instrument (totalstation).Through our knowledge in surveying and mapping technology and help from a carpenter, this investigation has been implemented. The setting out using a tape has been performed by letting the carpenter to set out windows, bathroom and water- and drain-details from baselines and drawing. The setting out using a surveying instrument was carried out by means of a Trimble Total Station. These two methods have been compared in order to detect and show the difference that occurs.The report shows the investigation background story from the practice of Swedish Mätcenter in Karlstad.A result of differences in accuracy and time is described in the report, as well as their theoretical consequences.
Does vaccination against Feline Parvovirus protect hospitalized raccoon kits from clinical outbreaks of parvoviral disease?
The Northern Raccoon (Procyon lotor) belongs to the Carnivore-family and is a species endemic to North America. Every year hundreds of orphaned raccoon cubs are admitted into the Wildlife Rehabilitation Center of Minnesota (WRCM), a non-profit organization where all injured or orphaned wild animals are admitted and receive quality health care with the goal of being released out into the wild.
The WRCM routinely vaccinate all of the admitted raccoon cubs with a killed feline panleucopenia vaccine, but despite this there are outbreaks of parvovirus infection every year where up to 50% of the admitted cubs have been euthanized or died. The objective of this study was to determine whether vaccinating the admitted raccoon kits has any significant protective effect to developing clinical parvoviral disease.
A single-blinded cohort study was designed with two parallel, independent groups. One group was given a dose of killed feline parvovirus vaccine at admission, and the other group was not given any vaccination at all. Assignment to the vaccinated or unvaccinated group was on a per-litter basis and done randomly by drawing lots out of a box.
Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)
Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the
impacts of realistic neonicotinoid exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and
geographical proximity, using GIS.

Finansiella nyckeltalens samspel som investeringsstrategi : En kombinationsmodell för att uppnå riskjusterad överavkastning
This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.
Analys av hemområdesstorlek hos mellansvenska vildsvin (Sus scrofa scrofa)
The wild boar population grows rapidly in number in Sweden, and it has been predicted that the annual number of shot wild boar will soon exceed the cull of moose. According to estimates, the Swedish population encompassed some 150 000 individuals in 2010. The mean annual harvest has increased by 30% since 1990, indicating that the wild boar is a species we must learn to manage sustainably. A successful management of the boars aims for a population in balance with agriculture and traffic, and also provides good hunting opportunities. For this to be possible, understandings of several aspects of the ecology of wild boar is needed.
The sows in this study had an average homerange of 707 hectares during summer, and 659 hectares in winter.

Indoor Positioning Using WLAN
This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..
Slitage på skogsbilvägar vid virkestransporter
This report discusses questions concerning wear on forest roads. The purpose of the work is to investigate if the wear on the roads will decrease when the speed limit gets lower for the trucks that transport the wood. A normal forest road, class B, was used in the study. In total 5000 m3f timber was transported on the road. Data about the road was measured with a profilograph car before and after the timber transport.
Användandet av propaganda i skapandet av en föreställd gemenskap
The purpose of this paper is to examine how propaganda has been used by two dictatorships, namely Nazi Germany and the Soviet Union under the leadership of Josef Stalin. By examining a number of propaganda posters and paintings, we aim to find similarities as well as differences in how the two nations attempted to create imagined communities amongst their people. While conducting this examination of the propaganda material, we have acquired and used some of the ideas of Benedict Anderson, who has coined a concept that he calls ?Imagined Communities?. In conclusion, it is established that the most obvious similarity is that both leaders are heavily included in their propaganda material, both pictured and mentioned in text.
