Instrumentbordets sterilitet
Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.
Vildsvinsskador inom jordbruket : hur stora är förlusterna?
Problems with wild boars are increasing in Sweden and some people argue that the wild boar population must decrease. This is mostly the opinion by farmers, while the hunters want more wild boars in Sweden. Today the population is the strongest in the south of Sweden and in the eastern parts of the country. However the population is growing stronger in other parts of Sweden as well. The population origins from these areas where they escaped from pens around 1970.
Jakten på det svunna Löddeköpinge. En studie av hälsa, karakteriserad av artros, kroppslängd samt trauma, i det medeltida Löddeköpinge
The purpose of this study is to assess the state of health of the individuals living in Löddeköpinge during the middle ages, whose remains were excavated by Chintio, H., 1975-80. The location is thought to have been a trading community that ceased to flourish towards the end of the Viking age. The main focus of the essay is to examine the occurrence of osteoarthritis (sv. artros), trauma, and analysis of stature, in order to understand population health during this time period. Osteoarthritis has never been researched in Löddeköpinge and the analysis showed that, of the 60 skeletons examined, 68,3% demonstrated some change in the skeletal joints, which is much higher than in the comparative material obtained from Lund and Sigtuna.
Förvildade husdjur : möjligheter och hot
Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall
Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.
Utvärdering av Group Development Questionnaire-interventioner på svenska arbetsgrupper
Arbetsteam har blivit en allt mer vanlig tillämpad organisationsform på dagens arbetsplatser. Att utforma bra metoder för att stödja arbetsgruppers utveckling är därför av stor vikt. Group Development Questionnaire (GDQ) är en metod framställd för att arbeta med grupper ur ett utvecklingsperspektiv. Denna studie utvärderar resultaten av GDQ-interventioner som genomförts på tolv svenska arbetsgrupper, i syfte att undersöka om positiva förändringar skett i grupperna. Resultaten visade inte på några större signifikanta förändringar i gruppernas fasutveckling.
STC-Plant Growth and Development, utvärdering av ett läromedel
Denna uppsats är skriven höstterminen 1997, då ett nytt läromedel började utvärderas i Linköping. Den svenska skolan har sedan en tid haft bristande natur- och teknikundervisning i de lägre årskurserna. Den Kungliga Vetenskapsakademien gav vissa av Linköpings skolor uppdraget att i lärarlag arbeta med ett nytt material, för att kunna se dess fördelar och brister. Materialet heter Science and Technology for Children (STC) och är framtaget av den amerikanska organisationen National Science Resource Center. Sedan utvärderingen av STC har läromedlet bytt namn till NTA (Natur och Teknik för Alla).
Skördesystem i vall, skördens storlek ochfoderkvalitet
The choice of harvest date for leys is one of the most important factors affecting the size and quality of the harvest. An early harvest gives a high nutritive value while a late harvest gives larger quantity. Today?s aim to produce high nutritive leys gives early harvest dates both in primary growth and regrowth in northern part of Sweden. The consequence is a growth in the autumn, a "third harvest".The aim of this master thesis was to study the effects of different harvesting systems and their effect on size, feed quality, wintering and economy for conditions in the northern part of Sweden.
Sjukhusets hjärta? : Informationsbeteenden hos läkare och sjuksköterskor på Universitetssjukhuset i Lund
This Masters' thesis is a study on the information behaviour of hospital personnel at the University Hospital in Lund, Sweden. A questionnaire was distributed to 301 nurses and physicians working in the intensive care unit, the population was reduced to 244 persons. The response rate was 52%, i.e. 125 questionnaires were completed. Nurses constituted 68 % of the population.
Dräktighetsdiabetes hos hund :
This article presents a retrospective case study combined with a review of the current literature concerning canine gestational diabetes. A total of 14 cases have been collected from six different clinics in Sweden. There are few previously published reports on canine gestational diabetes.
Gestational diabetes is a disease that rarely occurs in pregnant bitches. The condition is due to the rise of progesterone that occurs during the estrus cycle.
Pilot study: influence of the Samoan dog population on visitors
A range of public health and animal welfare problems has been shown to be associated with free-roaming dogs. With a high density of free-roaming dogs and with a major tourism industry, Samoan tourists are likely to be influenced by the presence of the dogs. The tourists are mainly from the Oceanic region; with New Zealand and Australia as the biggest contributors. The aim of this study was to examine the potential impacts of dogs on visitors to Samoa.
A questionnaire was handed out to 281 visitors all over Samoa, collecting opinions and information on visitors? experiences and behaviour regarding the Samoan dogs.
Organic acids in liquid feed for pigs - palatability and feed intake
Fermented liquid feed is well known for its health promoting effects on piglets. High levels of lactic acid are desired in the feed together with low levels of acetic acid and certain biogenic amines. Limits for acetic acid have been suggested to be 30-40 mmol/kg to avoid a decreased palatability of the feed; however, few studies have been performed. The purpose of this trial was therefore to examine which levels of lactic acid and acetic acid that can be accepted in a fermented feed without affecting the feed intake and thus the weight gain of the pig. A total of 60 pigs (Yorkshire/ Hampshire) were used in a trial during two weeks, between 9-11 weeks of age.
Analysis of MHC class II and monogenic eye diseases in the Scandinavian wolf population
ABSTRACT.
In the late 1960?s all the wolves in Scandinavia went extinct in the wild due to extensive hunting. In 1983 two new wolves immigrated and founded, together with a third immigrant in 1991, the population that exists today. Due to the fact that the population originates from less than a handful of individuals, the genetic variation is small.
Hur tiggeri konstrueras som ett socialt problem i den massmediala debatten
The Swedish stock-market gives investors an opportunity to benefit from the global growth while financing companies invests and contributes to a socio-economic development. Parallel to the ownership of the funds also follows a responsibility as companies in the funds affect society and the environment. The growth of savings in funds, combined with an increased focus on sustainability has developed SRI (socially responsible investment). Therefore it is interesting to examine whether responsibility is an exception, which only concerns SRI-funds or a general principle, which includes the whole Swedish stock-market.The results of the survey makes it clear that all the Swedish major banks actively works to integrate sustainability within the respective bank's business to achieve a more sustainable financial system. Thus concludes the investigation that responsible investments are a general principle on the Swedish mutual stock-market.How responsibility is integrated in fund management differ between the banks.
Cooking banana farming system in rural Uganda : a comparison between agroforestry systems and non agroforestry systems
The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today.
This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.
