Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

Most of the clothes sold in Europe today are produced in developing countries where the production costs are lower. The exploitation of the developing countries has led to that the inferior working conditions in these countries have attracted attention from media and NGOs. Globalisation makes company activities more transparent and the absence of transnational laws calls for alternative regulations. Many companies in Europe has since mid 1990s developed codes of conduct to satisfy the demands of external and internal stakeholders. EU also brought Corporate Social Responsibility to it?s agenda in the beginning of the 2000s and subsequently signals of approaching laws were given.

This thesis examines the implications of a shorter  intensive action research  project on  the formative assessments  key  strategies  four  and  five  that  are  activating  learners  as  learning  resources  for  one another and activating learners as owners of their own learning.  The research questions were ?How do the pupils experience the formative approach?? ?What didactic consequences does the formative approach  mean  for  the  role  of  the  teacher??  and  ?How  does  the  formative  approach  affects  the pupils?  results  on a  short term??. The results were that the  majority of the pupils liked the approach and that they felt like their efficiency increased. The didactic consequences were that the teacher had to spend more time on evaluation but had more time during the lesson to listen to and discuss with the pupils. The pupils? results were not changed in comparison with the control group..

The purpose of this research was to examine the current field of management in non-profit organizations, mainly focusing on managerial approaches, but also the impact of organizational size on the shaping of governance. Non-profits are widely discussed in contemporary research, particularly due to the increasing external pressure on voluntary organization to professionalize the way they work in line with standards in the private sector. Due to this our thesis aims to investigate whether professional, bureaucratic approaches are useful when governing a non-profit organization, or if social structures are enough to ensure goal congruence and efficiency. To conduct this research qualitative interviews were carried out and a case- study was made, using the Swedish Karate Federation as object of study. Results show that formal and more professional structures are useable to achieve efficiency and prevent inertia within the organization.

Many companies are currently working to optimize and streamline their processes and production lines to achieve higher profitability. In increasingly competitive markets, companies are working to find solutions to increase the value of their production with such a small use of resources as possible. A tool used to accomplish this is the Lean management system. Lean comes from the production system that Toyota has been developing since the early 1900's, The Toyota Production System (TPS). The Lean philosophy helps companies, by working towards continuous improvement in its operations, to achieve higher customer satisfaction, more efficient production and ultimately higher profitability. Many companies are working to implement Lean in their organization. But there are many who fail to implement a complete change towards Lean.

With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.
