Stridsyxor eller båtyxor : En diskussion om symboliken och dess betydelse

My intention with this paper is to try to understand the meaning of the double sex symbols which can be identified on a number of Neolithic so called battle axes from the region round the lake Mälaren in Sweden. My conclusions are drawn after having studied a number of archaeological thesises. I have realized that the society was egalitarian from what is said about the funeral habits since women and men were buried with the same care. Ceramics from the Skogsmossen site show a very long continuity over 15-20 generations. These facts indicate a peaceful society without traumatic breaks where knowledge would have been lost.

Tillverkning av mikronålar för medicinsk tillämpning

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.

Kartering av markföroreningar inom Skutskärs Bruk samt utvärdering av spridningsrisker enligt Naturvårdsverkets MIFO fas 2

With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.

Rabies : en utmaning för Indien

This literature study describes the ways in which the spread of rabies can be prevented in India, what guidelines are set and also which methods have proved most effective. Every year rabies causes the death of around 20 000 people in India, which makes the prevalence in the country the highest in the world. The main source for human infection is bite wounds from infected dogs. People and animals can be vaccinated both prophylactic and post-exposure prophylactic (PEP), despite this the disease continues to claim high number of victims. The majority of those dying are young men and children from the poorer part of the population. Knowledge among the Indian population on rabies and its transmission routes, wound care and vaccinations is very limited.

HUR KAN VI REDUCERA DEN INTERNA ÖVERGÖDNINGEN SAMT REGLERA ALGBLOMNINGAR FRÅN ATT NÅ EGENTLIGAÖSTERSJÖNS KUSTZON ?? : En vision om att återfå en balans i Östersjön genom att skörda algöverskott och använda biomassan som en framtida råvara.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

Energiåtgång och Kostnad för Interna Transporter

Detta examensarbete är genomfört åt Sandvik Mining and Construction inom ramen för det statliga samarbetsprojektet MinBaS II. Sandvik Mining and Construction är ett av Sandvik koncernens affärsområden och har en världsledande position på marknaden för maskiner och tekniska lösningar för bergbrytning m.mMinBas II är ett samarbetsprojekt mellan ett stort antal företag och universitet där staten står som huvudman och löper till 2010.Uppgiften med examensarbetet var att se om det fanns någon metod för att kartlägga de interna transporterna och beräkna deras energiåtgång i en bergtäckt. I brist på en befintlig skulle det tas fram en ny metod och sedan testa denna genom att genomföra fältstudier i en bergtäkt tillhörande Skånska Makadam AB för att sedan göra beräkningar på energiåtgången där.Volvo CE har under arbetet ställt upp med information och även givit oss SiteSimulation, ett simuleringsprogram för simulering av användning av deras maskiner.En del av arbetet var också att utreda hur energiåtgången ändras om förkrossen placeras på en högre respektive lägre nivå än det ställe där bergbrytningen genomförs.För att införskaffa underlag till beräkningarna har fältstudier genomförts i Skånska Makadam AB:s bergtäkt. Där gjordes bl.a. uppmätningar av den fysiska miljön som t.ex.

Ergonomi vid armeringsarbeten : En studie om möjliga förbättringar i arbetsmiljön vid armeringsarbeten

Injuries and sick-leave is a common feature for reinforcement workers today. This is mainlydue to the fact that reinforcement work is done in an exposed environment with many stressfactors and highly repetitive work. These operations are often carried out in unsuitableworking positions, these positions creates a major burden on the bones and joints and causesmicro- damages on muscles. With repetitive work these injuries are not given time to healproperly and will gradually become worse.The body will not be able to handle the stress of working in a work environment such as thisand musculoskeletal disorders can be a result of this. The injury will make itself known aspain in the musculoskeletal system and causes reduced movability; the injured worker willtherefore not be able to perform the same work tasks as before.

CAMPUS BTH - ett gestaltningsförslag och en studie av begreppet campus

This text answers the questions how do we define what a campus is, how the concept of the campus came to exist and how it is used today, and how the Blekinge Institute of Technology (BTH) campus can be designed according to site conditions and the conclusions drawn from case studies at Chalmers University of Technology and Karlstad University. The purpose of the case studies is to gain insight into their campuses advantages and disadvantages. This finally results in an interpretation of how the Blekinge Institute of Technology campus can be planned. A campus is the area of land on which a college or university and its surrounding buildings resides on. Campus as a concept meant a field at first, it later evolved at American universities due to their design of college campuses.

The Key Success Factors of Grameen Bank - A Case Study of Strategic, Cultural and Structural Aspects

The thesis aims to analyze strategic, cultural and structural aspects of Grameen Bank and its micro-credit project, in order to identify key success factors. A case study was performed with an inductive and qualitative approach, using semi-structured interviews. The data was collected by field observations and interviews on site in Dhaka, Bangladesh and surrounding areas.The main conclusion is that the critical success factor of Grameen Bank is the relationship focus, guiding and aligning its strategy, culture and structure. Also, local offices have been observed to utilize practices not permitted by the bank?s management, ultimately increasing the organizational efficiency..

Nerver i karpala flexorretinaklet på häst

The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.

African swine fever in Uganda : description of a recent outbreak and possible differential diagnoses

This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

Weblogindex: En studie av weblogindex utifrån Lancasters processmodell över traditionell indexering.

Many new electronic publication systems have arisen in the past few years, one of them is the weblog. In 1999 there were 23 weblogs, today there are millions thus a need for organisation has appeared, both special metadata and subject indexes have been invented and created. Due to the large amount of the latter we have in this thesis decided to concentrate on those close by the Scandinavian weblogindexes. A more international perspective would however have been possible, as very little is written on the topic. We have looked at these selected weblogindexes, trying to determinate whether they agree with F.

Internet - en plats där du inte behöver vara annorlunda : En kvalitativ internetstudie om personer med Asperger syndrom, om svårigheter och möjligheter som de möter genom samhällets konstruktion.

This study is based on a qualitative internet research about people with Asperger syndrome and their thoughts and opinions about the difficulties that occurs in the environment outside the home and their experiences of Internet. We have analyzed Internets social influences for those with Asperger syndrome, as a consequence of the difficulties that they meet in other environments. The constructed communities in the environment outside the home and the social interaction that occurs there is not adjusted for those with the diagnosis. This leads to difficulties to be there for those with Asperger syndrome. By doing a content analysis of the assembled data from a community site on the Internet, we found out that the environment on Internet is more comfortable for those with the diagnosis in several ways.

Patho-anatomical studies on african swine fever in Uganda

African Swine Fever (ASF) is one of the most serious transboundary swine diseases because of its high lethality for pigs, socioeconomic consequences, rapid and international spread and the absence of either treatment or vaccine. This Sida Minor Field Study (MFS) was carried out during fall 2010, as part of a larger collaborative research project called ASFUganda, focusing on the epidemiology of the disease in Uganda. The aim with this study was to get more knowledge about the pathology in cases of ASF in Uganda, by studying macroscopic and microscopic lesions in pigs with acute and chronic ASF and to detect the ASF virus (ASFV) in tissues by immunohistochemistry. The pigs were selected from the two different geographical locations in Uganda, Mityana and Gulu district, both with on going confirmed outbreaks of ASF. Necropsies were performed in the field, and the laboratory procedures at the JICA (Japan International Cooperation Agency) Veterinary Pathology Laboratory, Entebbe, Uganda, and at the Department of BVF, SLU, Uppsala, Sweden. Three pigs from an outbreak of ASF in Mityana district showed both the history and the clinical symptoms typical for ASF.

Modeller för brösthöjdsålder för tall och gran :

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.
