In order to optimize calf welfare and health it is important to know the behavior of cattle in free ranging conditions. When the cow is about to give birth to a calf she will leave the heard about 12 hours before. It is then rather obvious that isolating the cow about calving time in a single pen is imitating the cows? natural behavior. To save space and minimize building cost it?s common that the farmers build calving pens for four of five cows especially at larger farms.

Populärvetenskaplig sammanfattning: Planera dagsutflykten och upplev mer av Island. Island med sina aktiva vulkaner och stora glaciärer är ett populärt turistmål och antalet turister ökar år från år. Flertalet av de 350 000 utländska turister som årligen besöker Island anländer med flyg till huvudstaden Reykjavik. Från huvudstaden anordnas dagsutflykter genom en rad olika researrangörer. Man kan även planera en dagsutflykt själv, och köra med hyrbil.

To effectively manage a forest resource for both economic and other values good planning is required. The problem is complex since you want to know which forest to cut and when. Often a hierarchical planning structure is applied, including strategic (long-term), tactical, (medium-term) and operational level. Today SCA Forest is one of few forestry companies in the northern Sweden with an integrated forest wood supply and industry. The goals of the company are to supply their own industries with wood and to manage the resources of the forest through a long-term perspective with satisfactory profitability.

The purpose of this paper was to examine how young parenthood is represented by the professionals and their thoughts and experiences from meetings with the young parents, and how the professionals work with this group of parents. As professionals we refer to those who work with young parents, and the definition of young parents are parents in the ages 15-24. The paper also discusses what needs these parents have, and what kind of support the society offers, according to the professionals. The method we worked with was interviews and we interviewed six professionals to find out how the professionals looked upon the young parents and their situation. Earlier research has stated that young parenthood is associated with many risks and disadvantages for both the parents and their children.

Our purpose with this paper was to examine what effect a parent's drinking problem can have for the children in the family. A combination of literature study and qualitative interview analysis was used. The most important research questions were: How do the parent's problems affect the child? In what ways can the social network around the child help it to develop normally despite problems in the home environment? To what extent a parent's drinking problem affects a child depends on many different factors. Based on earlier research and interview data we drew the conclusion that growing up in a family where a parent has a drinking problem has a negative effect on all children.

Since events of September 11 and the subsequent conflicts surrounding the event, the war against terrorism has been constantly present. It has been used several methods and strategies to address these threats, including a method current in use, the targeting method. The method refers to use few but precise attacks to knock out key functions within these organizations, mostly individuals in the higher command and control structures within these organizations. The effectiveness of the method has been put in question when the majority of the terrorist organizations continue their strife, in some cases even increasing its intensity. The purpose of this study is to investigate which role the higher command plays in these organizations ability to wage war.

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

This essay deals with the subject of communication through Facebook. In this survey we studied 100 youths from Karlstad and their communication habits and behavior patterns on Facebook. The social network site Facebook has since its start in 2004 made a mark in modern communication. Today in 2010 the site has more than 500 million users. This paper wants to study what happens to other types of communication.

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

The aim of this essay was to investigate how social workers, within chosen Social services districts in the northwest of Skåne, work with children placed in foster care. Our purpose was to investigate the interaction between the child and the foster home from the perspective of the Ecology of Human Development. Our questions were:* How do the social worker prepare the child and the foster home before a placement?* What kind of support is offered to the foster home with the purpose of supporting the child?* How do the social worker make the childs contact with the biological parents easier?* To what degree does the social worker work on strengthening the child's network?* Which factors do the social worker decide the allocation of support?* What do the social worker think affects the work with the foster home from a society level?To answer our question we have interviewed nine social workers. We found that the social workers were generally good at perceiving how the micro- and meso-systems, and to a certain extent the exo-system, influenced the foster child.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Entrepreneurship is considered essential for the Swedish economy, as well as globally. Accordingly,massive efforts are put into creating environments that successfully can support new ventures. The business incubator is a prominent part of these efforts and is important especially for the knowledge shared within its internal network. The aim of this study is to further explore how different activitieswithin the incubator can influence the interaction, and thereby the construction of social capital,among the incubatees. Using a qualitative case study of three incubators, and the framework of theincubator model, it is concluded that three distinguishing components within the framework influence the interaction, namely infrastructure, mediation and business support.

Trådlosa nätverk är av naturen sårbara for avlyssning för att kommunikationen sker med radiovagor. Därfor skyddas trådlosa nätverk med kryptering. WEP var den första krypteringsstandarden som användes av en bredare publik som senare visade sig innehålla flera sårbarheter. Följden blev att krypteringen kunde förbigås på ett par minuter. Därför utvecklades WPA som ett svar till sårbarheterna i WEP.

Livskraftiga företag har en förmåga att använda sig av externa resurser för att kunna lösa sina problem där de interna resurserna inte är tillräckliga. Småföretag har inte möjlighet att ha alla resurser själva utan måste specialisera sig för att kunna bli mer konkurrenskraftiga i en ständigt ändrande omvärld.Syftet med denna undersökning är belysa vilka olika kommunikationskanaler småföretag använder sig av och vilka faktorer som påverkar valet när de söker externa resurser. Det teoretiska ramverket består av kommunikationsprocessen och kommunikationskanaler. Kommunikationskanalerna består av nätverk, internet, mässor och reklam.  Denna kvalitativa studie är utförd på småföretag inom metallbearbetningsindustrin.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
