This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

Changing of the hoof angle is a common method for the treatment of many lameness-related conditions (Moyer 1980; Stashak 2002). Various studies in the literature have indicated different results of the effect of changing the hoof angle on the movement of the distal limb. Our study investigated the effect of raising the heel of the forelimbs by 10,7 mm on the movement of the distal limb. Horses trotted on a treadmill at several predetermined speeds. The kinematics of the distal limb was determined and variables including the extension of the fetlock joint were determined.

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of pesticides on the cropland.

The Swedish social insurance agency provides financial support for families and children, but also for people with work injury, illness and at old age. During 2012 they saw the amount of notifications of insurance increasing in Sweden, which is a development that cost our society a great deal of money. With the aim to pursue a sustainable development I have therefore devoted this project to wellness and stress management within preschool.The employees of preschool are often dealing with a lot of stress, due to the big groups of children that causes high noise and sound levels. The high noise and sound levels is a contributor to stress which additionally can damage the health and cause impaired hearing loss. About half of the people around their forties until the age of retirement have difficulties understanding speech in large groups.The purpose of this project has been to investigate the causes of negative stress for my target group, women between 30-60 years old who works in preschool.

There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

The purpose of this study is to compare social media's role in the proactive crisis communication planning in two administrations, two companies and two non-profit organizations. A qualitative comparative study method has been used and people familiar with social media and crisis communications work from each business has been interviewed. The interviews have been transcribed and analyzed to discover the opinions and reasoning about how businesses work with proactive crisis communication and the role they give social media. The interviews were analyzed based on selected theories and previous research in strategic crisis communications, where issues management and crisis communication plans have a significant role. Also research on the pros and cons of social media and crisis communications channels have been used.

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Aren?t you tired of never finding stuff? Take a bits as example, do you store these lose in your toolbox or carpenter belt? What if you could have it all accessible and assembled in a tool, always at arm?s reach?Today bits are used together with electric screwdrivers and handheld screwdrivers in a greater spread. For these different types of storage, from pure storage boxes to complex tools with storage built in, exist. The professional craftsmen commonly use some kind of box where the bits can be stored. Even so they tend to store their bits loose in a carpenter belt or toolbox, since they want the speed and accessibility of carpenter belt over the storage box?s tidiness.The project was started in the fall of 2010 and a referents group was early put together to ensure that the developed product became as user-friendly and attractive as possible.

The failure of Structural Adjustment Programs and its neoliberal policies to effectively reduce poverty have led to the creation of Poverty Reduction Strategy Paper (PRSP) by The World Bank and International Monetary Fund. PRSP, connected to both the Comprehensive Development Strategy and the HIPC initiative, are built on the notion of national ownership and stakeholder participation and thereby expand potential conditionality to include matters of governance. This thesis examines the evolution of PRSP and how the process of participation affects national governance structures. By analyzing the role of rules and norms within the World Bank and IMF from a historical point of view the thesis explains why the participation process has developed the way it has. It concludes that neoliberal norms, still at heart within the World Bank and IMF, have an impact on the process of participation within nation states and thereby its governance structure.

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.
