Hinder för kunskapsdelning : Att skapa förutsättningar för mer effektiv kunskapsdelning genom reducering av hinder

In today?s fast changing environment it is important for knowledge intense companies that want to stay competitive to actively work with their knowledge, knowledge sharing and Knowledge Management (KM). Barriers decrease the efficiency of how knowledge is created, stored and shared, and they are therefore important to reduce or preferably remove making the KM activities result in as much value for the organisation as possible. To achieve this, it is important that the KM activities become a natural part of the employees? daily work.

Optimal välfärd och hälsa för kalvar :

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.

Olfactory responses of the parasitic wasp, Trybliographa rapae (Hymenoptera: Figitidae)

Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges. The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.

Innovativa passiva lösningar för  förhöjd klimatkomfort i kontorsmiljö

Innovativa passiva lösningar kan bidra till förhöjd klimatkomfort och sänkt energianvändning i kontorsbyggnader. I rapporten har flera passiva lösningar och deras egenskaper identifierats. Självdrag och växter har varit rapportens största fokus som fördjupningsdel. Självdragets förmåga att klara av ventilationsflödet i en kontorsbyggnad med atrium, belägen i Stockholm har simulerats i programmet IES-ve och dess CFD-modul. Då utomhustemperaturen ligger under 12 °C fungerar självdrag enligt rekommendationerna.

Den ekonomiska tillväxten : en redogörelse för pessimistiska och optimistiska synsätt

The economic growth we have experienced the last century is based on limited natural resources. Whether these resources will last for a further economic growth is widely debated. Pessimism and optimism have each been influential philosophies in debate whose opinions can be conceded as two opposing opinions. In this paper we have analyze these opinions from an economics perspective. To study this further, the construction and meaning of the pessimistic and optimistic arguments have been applied implicitly on the Leontief production function and the Solow growth model.

Bibliotekariers syn på Open access : Enkätundersökning bland bibliotek med inriktning teknik, naturvetenskap, medicin och farmaci

Open access to scientific literature on Internet is a concept which is supposed to change librarians' work. The aim of the thesis was to examine librarians' perception of Open access. A questionnaire survey was conducted among librarians at libraries with specialisation in technique, natural sciences, medicine and pharmacy in Sweden. Even though Open access can be regarded as an alarming for librarians' work, the results of the survey showed that the future of the librarians' profession can be positive if they flexibly adopt their work routines according to changes in publication forms and library users' needs..

Rörelsens betydelse för inlärningsprocessen.

The purpose of this examination was to se how exercise affects the learning capacity. In this work I have chosen to integrate natural science with sport and the target group was a primary department. The two areas I integrate with sports were: the digestive system and knowledge of deciduous trees. I split the class in two different groups. One group got to have a theoretical lesson and the other one got to have an exercise lesson.

Diskursanalys på den Etiopiska regeringens nationala handlingsplan om bekämpning av ökenspridning

In this paper discourse analysis on the Ethiopian National Action Program (NAP) to combat desertification is made. The aim is to describe how the overall image/picture of desertification, its causes, and effects and of possible solutions are presented in the NAP. The result of this analysis shows that the main cause of desertification is human activities mainly due to the poorly developed socio-economic situation in the dryland areas. It is indicated that an excessive dependency of the rural population on the natural resources, particularly land, is the major cause of land degradation and this deterioration of land is said to have been caused by the rapid population growth, overgrazing, forest clearing as well as past government and institutional failures. In addition it is indicated that the effect of desertification usually involves ecological changes that sap land of its ability to sustain agriculture and human habitation, therefore the most serious threat to human welfare.

Damages and problems in communal swimming facilities ? an inventory

Bakgrund: De flesta inomhusbadanläggningar är idag 30-60 år gamla och många anläggningar har stora problem med skador på både byggnader och bassänger. Skadorna är ofta så pass allvarliga att det inte längre är lönsamt att renovera utan på många platser planerar man att bygga nya bad. För att undvika framtida problem är det viktigt att dra lärdom av vilka skador och problem som har inträffat samt hur man vid nybyggnation och renovering ska kunna undvika dem. Vid byggande av dagens inomhusbadanläggningar tillämpas främst tidigare branscherfarenheter. Det faktum att så stora brister och omfattande problem förekommer, tyder på att kunskapen är otillräcklig.

Verkliga känslor, okänslig verklighet : Pathos i marknadsföringen hos icke-vinstdrivande organisationer

Hästtransportsläp - krav, utformning och funktion :

SUMMARY The interest of horses in the riding sector has increased the last decades. A large amount of horses are transported in a 1 or 2-horse trailer, which is pulled by a car. Today a large number of different products and designs of trailers can be found on the market. The difference in shaping of trailers depends on tradition and experience. There are no detailed directions on the demands for shaping of horse trailers today. The literature review contains a market analysis of both Swedish and imported horse trailers.

Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans

This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.

Det handlar om träd. Ett utforskande mönsterprojekt för textil

This is a pattern project for textiles, with main purpose to develop and challenge my design process and to experiment with a mix of different printing techniques. The goal of the project was to create three textile individuals as representatives of my experiments, inspired by natural surfaces.The world of fashion have been an inspiration and has been the model for these textiles, with its powerful and playful patterns. With the world of fashion as a model, I also chose to work with the materials habotai silk and silk velvet. The qualities of these materials has also been influential in my design language.The work has been very focused on experiementation and exploration, and resulted in three printed fabrics that I have chosen to call Björkalm, Lindstam and Lavbädd..
