The purpose of this study is to seek answers to an ongoing problem in the forest sector; why scarifying operators quit their job. Scarification quality is crucial for successful reforestation after clear felling. It is therefore important to keep good operators working in the business. To collect the desirable information interviews were made both with contractors who are working and operators who have stopped working with scarifying. The conclusion one can draw from this report is that the scarifying operator job needs improvement in multiple areas. The former operators are mostly dissatisfied with the stress, low wages and negative physical effects that this work brings..

This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.

This paper aims at assessing the relationship between female and male part-time employment and the business cycle in Sweden during the years 1987?2005 using quarterly time-series data and two alternative indicators of the business cycle. It further aims at determining whether the share of women working part-time has changed over time. Key results include that the relationship between the business cycle and female part-time employment is found to be significant and countercyclical. No significant effect is however found for men.

Schmallenberg virus (SBV) is a novel arthropod-borne orthobunyavirus emerging in Europe in 2011 to 2012. Acute SBV infection causes diarrhoea, fever and reduced milk production in dairy cattle, but it is mainly the reproductive disorders (abortions, malformed foetuses and stillborn animals) in ruminants that have caused substantial economical losses. The prevalence of the virus outside of Europe is poorly investigated. SBV or SBV-like antibodies were detected in Mozambique in 2013, which raised interest for a similar study in Tanzania. In this study in Tanzania, blood samples were collected from 478 sheep and goats from 39 herds in 15 different villages in three districts, covering areas in the north, south and east of Tanzania. The epidemiology of the virus was investigated by tracing antibodies by ELISA and mapping of the virus by PCR was started.

Migration is a worldwide phenomenon that has occurred for thousands of years in a vast variety of species. The general knowledge of migrating animals is poor even though billions of animals from a range of different groups migrate every year. The human impact on migrating ungulates is high and many populations are declining globally due to direct and indirect causes. Hence it becomes vital to study the migration phase and the habitat and resources selected during migration. The objective with this study was to identify the habitat characteristics and resource selection of moose during migration and compare the selection between different seasons and utilization distribution (relative frequency distribution for the points of location of an animal over a period of time) categories.

The voluntary none-financial sustainability report has become a trend within accounting. The environmental issues used to be driven by activists only, but lately it has moved in to the general agenda in many companies. Investors are starting to put more attention to the sustainability reporting as it is considered to add value to the company. There are several standard guidelines to be used when producing a sustainability report, one example is the GRI´s Guidelines that takes the following three dimensions in consideration: economy, environment and social. This Guideline is from an international perspective considered to be of good accounting practice (Ljungdahl 2008).

Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.

The transformation of the Swedish Armed Forces is bringing about major changes in many areas. Indirect fire is one capability affected by these changes. Financial savings, a shrinking organization and higher eligibility requirements mean that fewer soldiers will gain access to exclusive high-tech support resources such as the JAS 39 Gripen aircraft and the ARCHER artillery system. This thesis aims to examine whether access to indirect fire capability can be increased through the use of civilian products and communication networks. Technology development in the civilian mobile communications area is exponential and nations such as the USA, facing challenges similar to those of the Swedish Armed Forces, devote substantial resources to research and development.

Abstract   Cinematic time is the most complex of all: it is composed of public time (clock), personal time (experienced) and in addition, it can run backwards, be contingent, stored and (re)created. The present study examines some aspects of cinematic time, with special reference to the instant, the moment and the present. The strictly defined instant or moment does not exist. It is a passage between the past and the future and it is impossible to record on film or a photograph. One example is the moment of death, which is an abstraction with zero duration.

Background: The debate about environment, labor conditions and aid to developing countries has the last years been a much discussed subject The pressure on the companies to live up to their responsibility is beginning to be noticed in the market.Purpose: To find out if a retail company investing in Corporate Social Responsibility thereby direct can effect it?s stock value. Using interviews to investigate if and how stock analysts and corporate finance professionals valuate a company?s CSR initiatives.Theoretical perspective: The description of CSR is leading to the main theory, The Brand Value Change, and the Market Hypothesis. Additionally a theory of the Consumer Buying Process and CAPM-model about financial risks is presented.Method: An event study of 30 companies to investigate if there is any change in their stock values and interviews with three professionals from the financial sector to find out about their attitude to CSR.

The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.

As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.
