Fyra barns erfarenheter via interaktion - ett nedslag i tiden

The purpose of my study is to examine how children through interaction are recognized and understood by other children and teachers at the preschool for one hour in the afternoon. This study gives voice to what young children in preschool do after snack. The overall purpose of this study is to find out what young children's experiences will be in preschool through interaction. The purpose of my research is to gain knowledge about how the time and opportunity for interaction exists between children 1;7-2;5 years, and educators as well as other children, and how this interaction appears during afternoon activities in the preschool.My research questions are:1) What experiences do children get in terms of their development of identity for one hour in the afternoon? 2) How does the interaction that the youngest children are involved in during the afternoon appear? And how long time does every occasion last? The study is based on the interactionist perspective and systems theory.

Underlag till klimatledningssystem för skolor

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

Värmeförluster vid utvändigt placerade ventilationssystem

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms

This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.

Interdependence between seed age and aerated steam treatment intensities

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Positive human to cattle interactions and the possibilities to increase animal welfare, economy and safety for farmers

Cattle production systems are changing to bigger intensified systems with larger numbers of animals per farm and more free range systems while at the same time employing fewer people. Aversive handling has been known to affect cattle production negatively for many years, but lately scientists have started to focus more on what positive effects gentle handling and positive human-cattle interactions may have on beef and dairy production. Fear can cause high stress in production animals and this can contribute to not only reduced production within beef and dairy cattle, but also increased risks for accidents and decreased animal welfare. Therefore, by reducing the fear cattle experience of humans, it could be possible to increase production, decrease accidents and increase the welfare of the animals. Reducing the animals fear and stress can be done by simple means, such as walking and talking calmly around the cattle, associating humans to positive feelings (such as feed) and stroking the cattle?s body regions associated with social grooming.

Aktivitens betydelse för åldersrelaterad kognitiv försämring

The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and cognitive measures. The main findings suggest that activities are associated with cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..

Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Identifiering av det logistiska förpackningssystemet En studie av teleutrustningsindustrin

Background: Due to outsourcing, the material flows in the telecom equipment industry have undergone major changes, which in turn has imposed new challenges for packaging supplier Nefab who delivers to the industry. In order to achieve market intelligence, Nefab wants to map the material flows, and investigate possibilities of further reusable logistical packaging systems.Purpose: The purpose of this thesis is to describe the typical features of the logistical material flows in a technically based, rapidly growing industry, and analyze the driving forces and obstacles, which influence the selection of logistical packaging system. Procedure: After developing a theoretical framework consisting of general logistical theories and theories related to logistical packaging, we have interviewed companies in the logistics channel of Ericsson Radio Systems.Results: We have found the main characteristics of material flows in our investigated industry to be Variations in Demand, Focus on Time-to-Customer, and Globalization of Logistics Channels. Regarding driving forces and obstacles in the selection of logistical packaging systems, we have identified Transportation Characteristics, Customer Demands, Quality, Handling & Administration, and Current Packaging System as important factors..

Dialektanvändning hos barn med typisk utveckling : En jämförande studie mellan östgötska barn i olika åldergsgrupper

To explore how children use dialect, and whether the dialectal language develops during growth might be of interest from a speech language pathologist?s point of view as the dialect could influence the child?s speech. Previous research is often based on older material and/or examines the speech of adults.  In the present study, everyday language in groups of south- eastern Swedish speaking children was investigated. The aim of the present study was to examine to what extent typically developed children of the ages of  5, 8 and 11 years use dialectal language. A further purpose was to discover which dialectal characteristics that were present in the different age groups, and how they differed.

Elektronisk motorstyrning för ottomotorer

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Industriella kundrelationer i teori och praktisk tillämpning

The research area and research problem was further developed into three research questions. The research questions concerns the following subjects: the substance of business relationships and dimensions within relationships management that can be used in order to contribute to the development of a company?s business relationships.

Soil carbon, pH and yield development in a long-term humus balance trial

Agriculture has to be performed in a sustainable way in order to sustain high yields and to support a globally growing population. Functional soil properties are fundamental for high yields and in order to achieve good soil conditions sustainable management is a key. Loss of soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a cereal system with straw removal or returning and a ley system, all with different nitrogen levels.
