Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall

Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.

When Bad is Good

Within the last year many companies have proactively started to communicate their flaws and weaknesses, believing that this will lead to they being perceived as more personal and human. Dominos Pizza is one of many examples of a company using this practice as a strategic tool for communication. However, the problem concerning the above arises as we found that there was a very limited amount of research defining the effects of communicating flaws, where the company's both dispatcher and initiator. Our study aims to fill the gap between this growing trend and the limited research explaining the communication effects. The study was carried out as an experiment where a total of 420 respondents participated.

Utveckling och applicering av en aviditets-ELISA för bovint respiratoriskt syncytialt virus :

Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals. A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact. Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial. The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.

Debatten kring Patriot Act. American Library Association's och den amerikanska regeringens förhållningssätt till anti-terrorismlagen The USA Patriot Act of 2001

This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.

Faktorer som påverkar barns läsutveckling

AbstractThe purpose of the study was to examine if manual signs used as support to spoken and written language can be a god mnemonic for learning of word-pictures. I performed my study as an experiment in which I made a Memory game with word-pictures. I played the game with the children twice. The first time, we played without manual signs and the second time I used sign as a support. I observed the children and noted the words they learned to read with and without the support of manual signs.

Slöserijakt i betongdjungeln : En tidseffektivisering av monteringsprocessen inom stål- och betongprefab

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Logotypiskt : En studie om hur digitaliseringen harförändrat logotypers utseende

In this study we are seeking to discover the norms in the design of logotypes and how they havechanged over time. To achieve this we have chosen to analyze the logotypes of twenty companies withthe largest expenditure on advertising in Sweden. We mapped chosen design attributes within the logoto discover the similarities and then we selected the five oldest brands to analyze how their logos havechanged over time. The design changes in the logotypes over time is can be related to the changingattitudes of the general public and the designers ambitions to draw on convention to create iconic designthat will spark brand-recognition. However many changes can?t be directly explained through changesin convention.

Påverkan av skuggor från vindkraftverk

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Analytiker och riktkurser: - Varför bry sig?

The purpose of this master thesis is to evaluate how the current share price and market consensus affect security analysts target price and if an investor should pay any attention to it. Empirical data is primarily collected from qualitative interviews with ten security analysts but also from a quantitative e-mail survey. Our main finding is that security analysts are indeed affected by each others earnings forecasts as well as the current share price. This is not strange, it is in several aspects rational. Security analysts has often nothing to gain by standing out too much and not either by spending too much time trying to create their own opinions due to lack of time or the complexity of what is analyzed.

Drivkrafterna bakom sveriges moderna helikopteranskaffningar och avvecklingar

This thesis addresses the driving forces behind the Swedish state?s procurement of Helicopters 14 and 16 and the decommissioning of Helicopter 4. These actions have significantly affected the Swedish Armed Forces, especially the Helicopter Wing, in carrying out their operational tasks. On numerous occasions the Helicopter Wing has been unable to perform its tasks. For instance, the Nordic Battle Group 08 had no helicopters to exercise with and, until recently, Sweden had completely lacked the ability to hunt submarines with helicopters for almost ten years.This thesis also aims to compare the decisions in 1999-2000 regarding Helicopter 14 with the decisions in 2010-2011 regarding the acquisition of Helicopter 16, to find if there is a general trend and how much the Armed Forces were able to influence decisions.

Nattfasta i äldreomsorgen

Bakgrund: Det förekommer stora nutritionsproblem på äldreboenden i Sverige och andra delar av världen. Sjukdom och åldrande är riskfaktorer för näringsmässiga störningar. Undernäring hos äldre är associerad med ökad dödlighet och sjuklighet samt en ökad risk för trycksårsutveckling och infektioner. Socialstyrelsen har utfärdat en rekommendation angående nattfastans längd för att motverka undernäring och dess komplikationer, samt för att öka energi- och näringsintaget hos vårdtagarna. Syfte: Att belysa nattfastan på äldreboenden i en stad i södra Sverige samt undersöka kunskap och attityder om nattfasta hos omvårdnadspersonalen på äldreboenden.

Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Den vägda nyttjandeperioden och dess effekter på utvalda finansiella nyckeltal: En studie av bostadsrättsföreningars avskrivningstider på byggnader

Housing cooperatives in Sweden practice very long depreciation times for their buildings and assets, subsequently depreciation costs are very low. This study aims at addressing issues relating to potential upward revisions of these costs and the revenue levels needed by housing cooperatives to address these changes, while also providing a detailed summary of some chosen financial ratios under different circumstances. This study's results are based upon recent (2015) market data within the Stockholm region, collected through a manual process and analyzed quantitatively. On average, housing cooperatives EBIT do not cover their financial costs and have low profit margins. The average depreciation time is considerably above what a technical evaluation by other sources may state.
