En pilotstudie av unghästars användning av ligghall i grupphållningssystem
Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging.
The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.
Nationella proven i matematik? en tillgång för läraren? : Hur några lärare använder sig av resultaten på de nationella proven i matematik
The purpose of this qualitative study is to investigate how some teachers make use of the results of the national tests in mathematics to plan their teaching. The questions are how they plan their teaching in mathematics and if they use the results of the national tests to compare with their own teaching. Five teachers in mathematics has been interviewed. I have used unstructured interviews with open-ended questions, and I have been able to ask follow-up questions based on their answers. The analysis of the survey is made from a systems theory approach. The result of the survey shows that teachers make use of student performance to look at their own teaching of the current group of students. However, there is not enough time to rehearse and repair the deficiencies discovered in the national tests, which for some is perceived as a stress factor.
Aktiv bullerdämpning i ventilationssystem
Active headsets have been on the market for years and now it is time for
something else to enter the stage. The technology of active noise reduction can
for exmple also be used in ventilation systems for reducing ventilation noise.
An active control system principally consists of four important components,
namely the downstream error microphone, the upstream detection or reference
microphone, the digital signal processor (DSP) and a loudspeaker.
The upstream reference microphone listen to the primary ventilation noise and
sends it to the DSP which makes a phase shift to the signal and sends it to the
loudspeaker. The loudspeaker sends out the opposite waveform of the incoming
one and reduce the primary ventilation noise.
Styrsystemets roll i balanseringen mellan kontroll och empowerment : En kartläggning av ett styrsystem och varför användningen leder till observerade effekter på personalen
Problem discussion: That empowerment and autonomy can lead to desirable effects on employees is clear. Previous research has found correlations between empowerment and e.g. motivation, job satisfaction, productivity, loyalty and commitment. However, a control problem arises when employees have more freedom in decision-making which could potentially lead to undesirable outcomes. It thus becomes a type of dilemma for management and managers where you have to try to balance a restrictive use of the control system (to maintain control) and an enabling use (to promote empowerment).Purpose: The purpose of this study is therefore to identify how a company can use its control system in order to achieve empowerment while maintaining acceptable levels of control.
Sustainable Construction in the Transportation Infrastructure Industry? as a vision and in practice
This study has been conducted on behalf of Vectura Consulting AB with the purpose to examine how different actors perceive the dimensions of sustainability and sustainable construction. The purpose is also to provide an understanding of existing barriers and opportunities for sustainable construction within the industry and exemplify with different directions for the actors in order to develop sustainability. The study has approach the research problem by using systems theory, developed by Checkland, to identify the relevant system. Other systems theories has been used as an theoretical framework in order to identify barriers and opportunities, which in this study are based on Hughes?s theory about reverse salients and salients.
Evaluation of Ectopar for the control of the poultry red mite Dermanyssus gallinae
The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great
discomfort for the hens and effecting the production economically. Few efficient acaricides are available
and there is a need for new control methods since resistance has become a problem in some cases.
The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment.The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and incommercial and institutional laundries.If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemicalreaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors toElectrolux has developed its own systems that extinguishes fire inside a tumble dryer and customershave expressed desire to purchase a fire-extinguishing system. Therefore, the project team receivedthe task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumbledryer.The purpose of the project has been to develop a system that both detects and responds to fire in anindustrial tumble dryer to meet the competitors and to satisfy customers' requirements.The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop afully functioning prototype.The project began with information searches on a variety of methods to both detect and extinguish afire. Subsequently, a number of different methods were used to develop a final solution and make aprototype.The result of the project is a fire-extinguishing system that extinguishes a fire inside a dryer.
Brygder och besvärjelser : En arkeobotanisk studie av medicinalväxter och den medeltida staden Nya Lödöse
The study of medicinal plants is a popular subject that, at least in the archaeological sciences, has met a lot of criticism due to the lack of physical data. It is problematic to distinguish the medicinal plants from local flora since many herbs that were used often could be found in the nearby vegetation. The purpose of this essay is to archaebotanically analyze samples from the medieval town Nya Lödöse and compare the data with a previous analysis from the site and a literature study. The herbs meadowsweet (Filipendula ulmaria), lady?s mantle (Alchemilla sp.), sweet gale (Myrica gale), hop (Humulus lupulus), common tormentil (Potentilla erecta), St. John?s wort (Hypericum perforatum), henbane (Hyoscyamus niger), catnip (Nepeta cataria) and motherwort (Leonurus cardiaca) have been selected for closer analysis since they occur with frequency in the historical medicinal texts and in previous analysis made on the site.
Gränsöverskridande natur-och kulturvård : Konflikt, motsättning och samarbete i den pyreneiska gränstrakten Monte Perdido
Transboundary protected areas are a fairly recent concept that have been increasing in popularity and are increasingly being integrated into large international organizations? environmental policy making. This essay examines the phenomena through the cooperation between two national parks, Parc National des Pyrénées in France and Parque Nacional Ordesa Monte Perdido in Spain. The theoretical framework used in this essay is based upon border theory, focusing on the different factors that influence the behavior of the border dweller and how the different social conceptions of nature influence the way it is managed. The results in this study result from researching published and private documents from the national parks and interviews carried out with staff from the park administrations from both countries.

?Det var en tyst kamp? : En ekokritisk analys om utvandring och fo?ra?nderliga system i Vilhelm Mobergs Utvandrarna
The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.
Styrtransmission för bandfordon
The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.
