Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

A design methodology to mitigate timing problems due to long wire delays is proposed. The timing problems are taking care of at architecture level instead of layout level in this design method so that no change is needed when the whole design goes to backend design. Hence design iterations are avoided by using this design methodology. The proposed design method is based on STARI architecture, and a novel initialization mechanism is proposed in this paper. Low frequency global clock is used to synchronize the communication and PLLs are used to provide high frequency working clocks.

Continuously grazed grasslands have remarkably high plant species diversity. In Sweden this type of habitat has declined for the last two centuries. Changed land use has caused habitat fragmentation and loss of habitat quality. This has caused a great number of plant species to end up on the verge of extinction. To try to save this unique habitat and the species that are tied to it, lots of resources are laid on restoration of abandoned grasslands. In this study, plant species richness of continuously grazed, abandoned and restored grasslands were related to degree of overgrowth, time since overgrowth started and rate of overgrowth.

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Syftet med denna studie är att undersöka vad som händer i olika naturvetenskapliga situationer i den fria verksamheten i förskolan. På vilket sätt tas sådana situationer tillvara på av pedagogen? Jag har använt mig av videoobservationer i två förskolor i Mellansverige för att försöka upptäcka situationer i den fria verksamheten som har potential att bli en naturvetenskaplig lärandesituation för barnen. I studien observerades 11 pedagoger. Resultatet visade att det finns potential för att utveckla naturvetenskapligt lärande för barnen i den fria verksamheten i förskolan.

Background: With the increased globalization food prices went down for a while, only to skyrocket to new levels. Prices of organic food, which already were more expensive than conventional, are now even more expensive. The current financial crisis results in reduced consumption which creates a threat to the smaller grocery stores. Globalization and the increased competition have had a negative impact on the environment but at the same time the desire to solve these issues has increased appreciably. The environmental aspect has been given higher priority by the individual, which led to a wider range of organic products and dramatically increased the number of stores selling organic products, leading to a greater competition among the stores selling organic food.  Problem definition: What factors are important for organic retail business long term survival?Purpose: Trough case studies analyze and evaluate the organic niche retail companies? strategies of marketing.Methods: This study is based on both qualitative and quantitative research methods.

This study has been performed at a smaller high school and with its industry students, the high school is located in a small industrial community. The purpose of my study has been to find out what students think about their work with the project work, what they think has been positive and negative, how their motivation is influenced by the work on the project and if the work has been affected by factors outside the school world.The interviews have been carried out like normal conversation with open questions. The students who participated in the study comes from the school where I did my internship. The selection was done by asking all students from a specific course, those who were positive to participate are also the ones I have chosen to interview. My main study results, in summary, described as the students, once they were inside their work were positive to the project work and felt motivated in their work. Negative experiences, for the students which attend a practical program, has mainly been economic, as the school does not provide any financial support.

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

This thesis investigates how recipient countries' domestic type of democracy affects its inclusive ownership in international development cooperation. This is done by examining Swedish development cooperation with Rwanda and Tanzania during the period from 2010 to 2014, a time when ownership - a concept which emphasizes recipient countries' leadership over its own development - was a central part of the international development agenda. The two cases were selected through a most similar case design where the value of potential explanatory variables was similar, except for the recipient countries' types of democracy. Furthermore, the case study uses a comparative analysis to analyze strategies and reports done by SIDA and the Swedish Ministry of Foreign Affairs. Previous research focuses on the exclusion that national ownership can result in, in undemocratic national contexts. The main argument for this should be seen as the fact that ownership can not be representative if the power of the recipient's development agenda is limited to a decision-making elite.

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

The aim of the present study is to describe the experiences of high school students as regards the effects of their activities, in and out of lessons, being published on the web. In addition, a further purpose is to acquire knowledge about whether a website could be used as means of increasing the students level of attention, and focus, to their activities in school; and, furthermore, how such a website should be designed to correspond with the students requests.The implemented methods are interviews with students, school administrators and teachers. A survey was conducted covering the student?s personal experiences and opinions. Furthermore, an interface test of the website was performed.

Background: Fall injuries are a costly problem for society, with costs ranging up to 14 billion a year. In addition to economic loss accidental falls also creates human value losses and reduced quality of life for its victims. In order to prevent the occurrence of injury related to accidental falls healthcare providers utilize various scientifically developed risk assessment tools, one of them being Downton Fall Risk Index. Method: Empirical, quantitative cross-sectional study. Objective: The purpose of the extended essay was to describe the categories in Downton Fall Risk Index that have a bearing on patients' risk of falling while in hospital and in municipal care, and to illustrate how nurses can use the fall risk assessment tool.

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.
