Factors influencing pig behaviour during unloading from a transport

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

Torkat bioavfall som jordförbättringsmedel

The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.

Solvärme med säsongslager i Lyckebo

The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.

MPD-vågformer för helikopterradar

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

På låtsas och på riktigt. Verklighetsnära lärande i Freinetpedagogik och entreprenöriell pedagogik

Structuring education so that students can discover connections between schoolwork and their everyday lives is a crucial task for a teacher. This is especially true in today?s school system that seeks to foster a spirit of lifelong learning, since educational motivation depends on being able to connect to the tasks at hand. In a system where these connections are not present, students will be motivated only by institutional mechanisms such as test results and grades. This leads to them using a number of techniques for ?optimizing the system? by getting maximal results for minimal effort. This essay looks at two pedagogical movements that aim to decrease the gap between schoolwork and students? reality.

Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus

The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.

Behöver du företag på sociala medier eller behöver företagen dig? : En studie om kunders behov av företag på sociala medier och påverkan på relationer

Social medias impact recent years has been huge and an increasing number of companies have started using the services. The benefits for companies to be available thru social media are many and the costs are low. Social media makes it easier for companies to get in touch with their customers and at the same time they reach out to a lot of people since the number of frequent user?s constantly increase. A major part of the information that is available is seen from a company?s perspective and what benefits they can take advantage of thru social media.

Att spela ett yrke : En kvantitativ studie om svenska speljournalister och deras professionalisering

This work aims to improve our knowledge about Swedish video game journalists, a new occupation in a quickly expanding business. Through a survey sent out to over 50 Swedish video game journalists, the result indicate some unexpected facts. Men largely dominate the profession; just 10 % of the work forces are females. This relation was notable in our survey, as well as in earlier studies. Video game journalists between 26 and 35 years old seems to be the largest age group, which we think is a bit surprising considering how new this form of journalism is, and the fact the internet provides opportunities for every enthusiastic video game writer.

Att göra sig förstådd : En kvalitativ studie av hjälpmedelstödd kommunikation mellan två personer utan funktionshinder

I den här uppsatsen beskrivs kommunikationen stödd av ett talbaserat kommunikationshjälpmedel mellan två personer utan funktionshinder. Beskrivningen görs utifrån ett teoretiskt perspektiv som tar hänsyn till att kommunikation är en interaktiv social process och fokus ligger på processen i vilken man skapar samförståelse. En kvalitativ metod användes där observationer samlades in genom videoinspelningar av personer involverade i en måltid. Materialet analyserades genom en kommunikationsanalys i vilken fokus låg på hur samförståelse uppnåddes. Hastighetsbegränsning och symbolurvalet visade sig vara egenskaper hos kommunikationshjälpmedlet som påverkade kommunikationen på så sätt att deltagarna på grund av dessa fick reparera eller avbryta den aktuella konversationen.

"Genus är inskränkt!" : En komparativt inriktad studie av genuspedagogik på förskolor i New York och Stockholm

The purpose of this thesis is to examine how teachers work and reflects on gender education in preschools. We also want to take part of how teacher?s thoughts are reflected in the physical indoor environment and how the environment is designed by reviewing the rooms furnishing and the selected materials. We will do this by visiting a number of preschools located in Stockholm and New York. We have chosen three questions to get the answers on our purpose.How teachers reflect around gender pedagogy are, and how the thoughts are expressed in the practical work.How the teachers communicate with their co-workers about gender pedagogy.How the teachers own thoughts and reflections on gender pedagogy have been expressed in the physical indoor environment where the children stay during the day. We have used interviews and observations as a method to gather the information that we needed to answer our questions of the thesis.

Att mötas på de ungas villkor : - En kvalitativ studie om ungdomsarbetares erfarenheter av att bedriva stödsamtal med unga på internet

With this research we aimed to seek how youth workers express their experience of counselling on the internet compared to traditional counselling face to face with a theoretical ground in semiotics and symbolic interactionism. Our questions were 1) How do youth workers describe their experiences from anonymous, faceless online counselling? 2) How do youth workers experience the differences between online counselling and the traditional face-to-face counselling? 3) Which possibilities and difficulties do they see in online communication with adolescents? We used semi-structed interviews with seven youth workers. Six of those are active in non-profit organisations, and one in social services. The results from our interviews showed that the interviewees saw that misunderstandings were more frequent on the internet, but that online counselling with adolescents still was easier than in the face-to-face meetings.
