Running water-pathways have played an important roll in Sweden and frequently been manipulated. One profound change was made during the period of logging when streams were cleared from obstacles as big boulders, sharp bends and side-streams. Dams and different constructions gave control of the stream water and the streams became channel-like with a homogen structure. This interference gave problems for many fish populations and resulted in a shortage of feeding habitat, over-wintering habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural temperature fluctuations. Many of these historical changes of the watersheds are now subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.

Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

The purpose of this study is to gain increased understanding of managers´ attitudes and knowledge about its role in the internal organizational communication. We want to understand how managers define dialogue and further understand the role that dialogue plays for managers. We want to see whether the different managers highlight some common foundations or differences in the dialogue. With the help of the following two questions we wish to understand managers´ relationship to the dialogue within the internal organizational communication: -What meaning does the dialogue have for managers in the private sector?-What role does the dialogue play in the internal organizational communication according to these managers? We use qualitative interviews as the data collection method of our material. Using material from the interviews and mainly in accordance with William Isaacs? theory of dialogue, wecan answer our questions. The result shows that managers' views on the dialogue in many cases are similar to Isaacs? vision but differs in part. The managers believe that employees are there to contribute to the company.

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

The purpose of this thesis is to investigate the employees´ duty of loyalty to their employer when making statements on social media networks and if this opposes the employees´ right to freedom of speech. Another purpose of this thesis is to investigate freedom of speech from an EU juridical point of view. Also a discussion concerning gender issues on this subject takes place is presented in the thesis. The questions to answer the purpose of this thesis are the following: Where is the line drawn for what an employee can publish on a social media network without breaching their duty of loyalty towards their employer?, and How does an employee´s freedom of speech relate to these types of statements on a social media network? The method used for this thesis is the classical legal method.The legal inquiry shows that duty of loyalty is a hidden clause in all employment contracts, and it must be respected by the employee.

The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production. The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with the measured time of usage.

The workplace has a direct impact on the physical, psychological, economic and social well-being of the workers. A healthy workplace leads to increased health among the employees which also makes the employees more productive (Källestål, 2004). A poor working environment can have negative consequences for individuals, companies and society (SOU, 2009:47).This is a qualitative study that investigates companies? view of health promotion and how they practice health promotion in working life. Five private and five public companies, with representatives from the management were interviewed.

Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this case bridges or culverts have to be built. There are many different kinds of culverts and depending on what type you choose and how you place the culvert, the watercourse and the water organisms can be harmed in different ways.

Syftet var att kartlägga arbetstillfredsställelsen hos chefer i svensk äldreomsorg samt undersöka om det fanns några skillnader mellan chefer i privat och offentlig verksamhet. En rikstäckande webbenkätundersökning (N=104) genomfördes. Denna genererade både kvantitativ och kvalitativ data. Cheferna som sammantagen grupp visar på en förhållandevis hög arbetstillfredsställelse. Resultatet visade dock att det fanns signifikanta skillnader mellan privata och offentliga chefer vad gäller arbetstillfredsställelse.

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.

This essay is about how organizations reveal their employees in the annual report. The purpose of this paper is to examine the extent to which organizations reveals their employees in the annual report, and the purpose has three questions: How do the organizations present their employees in the annual report? What do they choose to report? What motives lies behind?The problem today is that organizations can´t account the employees as assets, they can only be accounted as an expense in the income statement. This can lead to that stakeholders can´t convey an organization's "true" value.With a combination study, we examined how organizations certified by Investors in People presents the employees in their annual reports. In the framework, we have, among other things dealt with personnel mandatory disclosure in the Annual Account Act, the difference between private- and public sectors accounting.

Swedish school system is today victim of facing competition. Today sees the school leadership the students like customers whom they depend to operate their school. But I have asked myself, what will be the new students see and how much this spectacle in both money and time that project will cost for the municipality and school teachers. The question is if whether the school will be better when the competition becomes school or just better marketed? I'm interested in how clearly ideologies emerge in schools brochures if we study them at critically and analytically way.

Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare. The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.
