This paper presents the result of a master thesis project at 30 Hp, master of industrial engineering at Luleå University of Technology. The project was performed during 20 weeks, spring 2014, in collaboration with ABB Control Products in Västerås. The aim of the project was to evaluate two half-automated assembly lines for a new generation of contactors, the NAFC assembly lines (New AF Conductor). The aim and purpose of the project was achieved by answering the following questions:? How are the ergonomic working conditions at the NAFC assembly lines during spring 2014?? Which areas at NAFC assembly lines can be improved for the work environment?? How can the ergonomic work conditions improve at the NAFC assembly lines?Literature reviews were performed from earlier research papers and articles of the ergonomic, musculoskeletal and work environment subject, from where a number of chosen methods and tools were used to perform the ergonomic evaluation.

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.

Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..

Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews.          The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.

Schmallenberg virus (SBV) is a novel arthropod-borne orthobunyavirus emerging in Europe in 2011 to 2012. Acute SBV infection causes diarrhoea, fever and reduced milk production in dairy cattle, but it is mainly the reproductive disorders (abortions, malformed foetuses and stillborn animals) in ruminants that have caused substantial economical losses. The prevalence of the virus outside of Europe is poorly investigated. SBV or SBV-like antibodies were detected in Mozambique in 2013, which raised interest for a similar study in Tanzania. In this study in Tanzania, blood samples were collected from 478 sheep and goats from 39 herds in 15 different villages in three districts, covering areas in the north, south and east of Tanzania. The epidemiology of the virus was investigated by tracing antibodies by ELISA and mapping of the virus by PCR was started.

It´s important when you are about to build a new stable or just increasing your production that you choose the right housing system and that it fits your own farm. In this study I have put together facts about different housing system for fattening bulls in order to get a clearer picture of witch system is the most suitable for my own farm depending on the conditions I have. The background of this work is my own interest for breeding bulls and I will hopefully increase my own production. Due to this I wanted to learn more and increase my knowledge about different housing systems. Through a literature study I have found out the facts about the housing systems I find suitable for housing bulls.

Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW. To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

Swedish agriculture faces future challenges regarding food production and land use. Increased competition for agricultural land creates complex situations, where conflicts may arise when productive crop land is in demand not only for food production but also energy- and fodder production. On top of that there is an obvious conflict of goals between agricultural production and non-agricultural exploitation of agricultural land. In several emerging economic regions it is noticeable how agricultural land is being expropriated for development of urban settlement and infrastructure, carrying potentially significant long-term effects. During the last decade the exploitation of agricultural land in activities other than food production has increased in Sweden and is expected to continue in the same manor. Approximately 700 hectare of land in Sweden is diverted from food production, annually, and in 2013, the Uppsala Municipality showed the greatest change in land use of all municipalities (SCB, 2013).

In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..

Automationscenter & Bråvalla Elteknik AB is a company that offers the market completed total solutions where the customer can operate and monitor their production from the terminal. In these total solutions they lack standard circuit which are developed by the company and which could manoeuvre/control/monitor controlled process objects. This report defines the work of developing the most common standard circuits.The report is initiated by a short theoretical part about PLC and the PLC system, with a connected terminal, which has been used. Thereafter, the turnout of the demands of specification is reported, after discussing with the supervisor in the course of the project. The report concludes with a disclosure of how the programming, the documentation and the testing have proceeded and a final discussion concerning the project and proposals on continuation.The result is a CD with the documentation of standard circuits and how they are implemented in a new project.

This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).

The public sector is a major purchaser of goods and services. By setting requirements for environmental and social considerations in public procurement, an authority has the possibility to use consumer power to influence the actors in a market. The purpose of this paper is to investigate public procurement of textile products in a municipality, in order to gain knowledge about factors that may be important for the use of environmental and social criteria. Håkan Hydén´s (professor in sociology of law) norm model was used as the basis of the analysis, where the conduct was investigated along three dimensions of the norm ? willingness, knowledge and system conditions ? in order to identify underlying factors that can influence the process.The results ? analyzed by using interviews and documents ? show that the procurer's willingness, motivation and knowledge are important factors in this context, as well as the political priority of the municipality.

Foreseeing future changes in economic activity is of up most importance to a wide array of actors. The time lag in the presentation of official GDP statistics means that to somewhat accurately capture a tendency of where the business cycle is heading one need turn to qualitative sentiment indicators such as Purchasing Managers? Index (PMI) and official sentiment indicators for valuable clues. This thesis uses in-sample and out-of-sample methods to evaluate how well PMI and official Business Tendency Surveys (BTS) in Sweden and Denmark fair against the year-on-year growth rate of industrial production. Moreover, various Swedish regional sentiment indicators get examined and a case study of the indicator for the Öresund region is performed.

American bison (Bison bison bison) is a new species in Sweden and was introduced in the year 2000. In this study the result of an interview and a field investigation is presented. The aim was to investigate the health and parasite status in Swedish bison herds. The most common reason to begin with bison breeding was meat production and/or sale of breeding animals and tourism. The Swedish breeder?s experience of bison is that they in general are healthy.
