Energieffektivisering av flerbostadshus i miljonprogrammet
This thesis has been written with our society?s current energy-situation in mind.Although it only deals with one particular block of buildings, the solutions and suggestions presented herein are quite applicable on other objects of the same type.This thesis is intended to be used as a guideline for energy-preserving projects in general, with an eye to buildings erected during the Swedish ?million-programme? in the sixties and seventies.The paper starts with the acquiring of all necessary blueprints and technical specifications. It then moves on to a thorough description of the buildings in question, and their heating- and ventilation-systems.Followed by this the reader is guided through the successive stages of energy-perseverance measures that are available, and possible. Reasoning around the economic factors concerning all measures is also held.The paper ends with conclusion, and a discussion concerning the delicate issue of the higher return-temperatures possibly reaching the district-heating plant..
Politisk styrning för ökad digital delaktighet : Aspekter av "governance" och "government"
Bachelor thesis in political science by Malin Bergkvist, autumn 12.Title:Political governance for increased digital inclusion.Subtitle: Aspects of "governance" and "government".Supervisor: Joachim Åström. While digital inclusion is a hot topic in both academia and in policy circles, little research is done when it comes to governance issues. To help filling this gap, this essay asks which mode of governance is dominant in the field of digital inclusion. What aspects of governance "governance" or "government" is the dominant in the field of digital inclusion, and is it possible to see any difference in how the state governance is described by the government and perceived by other actors? To answer this overarching question, two sub queries are formulated and analyzed. First, what aspect of "governance" or "government" dominate when state governance of the area are examined based on how the government describes it? Second, what aspect of "governance" or "government? dominate when state governance are studied based on how the perceived by other actors and stakeholders active in the field.

Nötkreaturens val av betesvegetation på naturliga betesmarker :
This study concerns the type of vegetation selected by cattle grazing on semi-natural pastures, and whether the selection depends on the nutrient content of the vegetation or on other factors.
The study was carried out in three different semi-natural pastures in the Uppsala area during June, July and August in 2006. The three pastures were first surveyed, mapped out and divided into sub-areas with regard to the type of dominating vegetation. The vegetation types identified were: wet, mesic, dry, wooded, pasture with signs of former cultivation (arable). Within each vegetation type three 1x1 m sampling plots were laid out.
The grazing behaviour of the cows was recorded in a behaviour study.

Kontroll av rengöring med ATP-luminometer hos livsmedelsverksamheter med pizzaberedning i Sundbybergs kommun
This BSc thesis is a part of an initial step of a collaboration between Skansen and Kenyan Wildlife Service (KWS) and constitutes of an inventory of the Nairobi Animal Orphanage run by KWS. Animal Orphanage takes care of orphaned and injured animals arriving from throughout Kenya. The project started out as a refuge and as a temporary place for animals in need of care and help. With time it has evolved to an establishment that resembles and functions more like an animal zoo. The aim of this inventory is to focus on how the biological needs of Congo grey parrots ( Psittacus erithacus erithacus) and cheetahs (Acinonyx jubatus) are met, in terms of management and housing.
Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan
The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.
Hälsobeteende bland sjuksköterskor och undersköterskor : En studie om oregelbundna arbetstider på Ålands hälso- och sjukvård
In our everyday life we are faced with many choices that have consequences on the environment. One of these is the food we choose to eat since food production has a big impact on the environment. In organic production the aim is to have a natural production process, where environmental impacts are minimized. By choosing organic food it is therefore possible to contribute to a better environment. A large number of meals are served every day in the public sector, which makes it an important player in the consumer sector that could make a major difference for the environment..
Ombyggnation till passivhus
Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.
Fuktrisker i kallvindsutrymmen - problem och förbättringsmetoder
This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.

Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter
Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals.
The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.

Torkklimat under byggproduktion : En kvantitativ studie baserad på klimatdata och litteraturstudier
En utmaning under produktionen är uttorkning av byggfukt i byggnadens betongbjälklag. Om uttorkningen försenas kan golvbeläggningar inte appliceras i rätt tid, men att arbetet forceras är inte ett alternativ, då risken finns att fuktskador uppkommer under driftsskedet. Avgörande för att uttorkningen skall fortskrida enligt plan är att torkklimatet i byggnaden är gynnsamt för uttorkningsprocessen. För att kontrollera torkklimatet genomför företaget ett omfattande arbete genom att mäta klimatet, där dataloggar på olika platser i byggnaden registrerar luftens temperatur och relativa fuktighet. Tillsammans med trendmätningar i betong är tanken att insamlad data skall ge en bild av hur uttorkningen fortskrider.
