Tyst kunskap och produktdatasystem vid medicinteknisk tillverkning : Pilotstudie av system för produktdatahantering och kartläggning av den tysta kunskapen vid Nationellt respirationscetrum, NRC

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

The possible role of transmissible gastroenteritis virus (TGE) and porcine respiratory corona virus (PRCV) in the mortality of Ugandan back-yard piglets

In Uganda, small scale pig production plays a major role for households to earn a living and to secure their access to meat. Piglet mortality due to diar-rhoea-related dieseases is high. In an attempt to understand the underlying causes for this high mortality this study aims to investigate the role of trans-missible gastroenteritis virus (TGEV) and is a part of a larger project con-ducted at Makerere university in Uganda. A complicating factor in this investigation is the porcine respiratory corona-virus (PRCV), a stabile mutant form of the TGE virus. The occurrence of this virus had shown to alter the impact of TGEV in e.g. Europe and North Amer-ica.

Itrakonazol till häst : en farmakokinetisk möjlighet?

Itraconazole is a third generation azol, a fungicide which acts by inhibiting ergerosterol synthesis in the fungal cell membrane, and thereby disturbing fungal regeneration. It has proven to be less toxic, to have a broader spectrum of activity and to be more potent than its predecessor ketoconazole. Itraconazole is only available in therapheutics approved for human use. Pharmacokinetic studies has been performed in humans, dogs, cats and laboratory animals. Although itraconazole has been used tentatively with good effect against fungal infections in horses, no pharmacokinetic studies have yet been done.

Effects of milking system on plasmin and plasminogen activity in bovine bulk milk

Protein is an important component in various milk products and has a crucial role in the final quality. Excluding non-protein nitrogen, bovine milk contains about 3.3% protein whereas about 80% of this fraction consists of casein. There are four major members in the casein family: ?s1-casein, ?s2- casein, ?-casein and ?-casein. Proteolytic enzymes are the cause of degradation of the economically important milk proteins.

Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs

Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.

Glukos och leucin som potentiellt hjälpmedel i återuppbyggandet av muskelglykogen efter hårt arbete hos travhästar

The aim of the project was to study the effect of oral administration of glucose and leucin on the resynthesis of muscle glycogen after intense exercise in Standardbred trotters. In a crossover design, 11 Standardbred trotters performed a standardized exercise test on two occasions in order to deplete muscle glycogen. The exercise test comprised a warm up period, 7 repeated bouts of exercise on an uphill 500 m slope, and a recovery period. After the exercise test horses received: 1) a solution of glucose and leucine via a nasogastric tube at 0 minutes and at 240 minutes post exercise and a single bout of glucose at 120 minutes post exercise or 2) water (placebo) at 0, 120 and 240 minutes. Blood samples for measurement of glucose and insulin concentrations were collected at rest, when the horses returned to the stables directly after exercise and throughout the 6 hour recovery phase. During the first recovery hour, samples were collected every 15 minutes and then every 30 minutes over the next 5 hours.

Analys av algoritmer för detektering av resonansfrekvenser i vibrationsmätningar på överhettartuber

På överhettartuber i värmepannor bildas beläggningar på grund av sot och partiklar från förbränningen. Beläggningarna isolerar överhettartuberna vilket försämrar värmepannans verkningsgrad. Sotning av tuberna sker under drift och ett system som automatiskt kan beräkna hur mycket beläggningar som finns på tuberna skulle kunna göra sotningen mer behovsstyrd.Resonansfrekvenser hos överhettartuberna påverkas av masspåslaget som blir när beläggningar bildas. En förändring i frekvens kan då översättas till en förändring i massa. Vibrationsmätningar har gjorts med töjningsgivare som är monterade på överhettartuber i en av Ryaverkets pannor och i SAKAB:s panna.

Bestämning av syntetiska cannabinoider med gaskromatografi-masspektrometri

This thesis has been performed at Clinical Chemistry at Sahlgrenska University Hospital in Gothenburg. The purpose of the project was to investigate new and alternative ways to determinate synthetic cannabinoids by gas chromatography-mass spectrometry. Currently, the possibilities to quantify synthetic cannabinoids are very limited. This can lead to an increased use of synthetic cannabinoids as the risk of detection is low, which may be known by drug users. The synthetic cannabinoids are sold mixed with different herbs and have varying names like Spice Gold, Spice Silver, K2, Smoke and Pot-pourri.The synthetic cannabinoids analyzed were JWH-018 and JWH-073, which are commonly found in seized Spice material.

Svensk vindkraft

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

One problem though is that the domestic waste, particularly the source separation, at the three resident blocks for students? isn´t working very well. This creates inconveniences for people and environment as well as decreasing the impression on the estates.This project has had the ambition to improve the domestic waste and increase the amount of source separation at HFAB´s student hostels.

A screening for Schmallenberg Virus among sheep and goats in Tanzania

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.

Fruktosamin som markör för diabetes mellitus hos katt :

Diabetes mellitus is characterised by persistent hyperglycemia in all species. Fructosamine is a glycated protein reflecting blood glucose concentration during the preceding weeks. It has become a valuable analysis to differentiate persistent hyperglycemia from transient stress induced hyperglycemia in cats. It is also used to evaluate current therapy in diabetic patients. Although fructosamine is a well accepted analysis, it is sometimes regarded with scepticism.

4-1BB is up-regulated in human mast cells, when exposed to tumor conditioned medium

Mast cells have for a long time been known to accumulate around tumors (Maltby et al., 2009). Studies show that they may be important and sometimes essential in tumor angiogenesis, tumor growth and metastasis of tumors (Soucek, et al., 2007; Xiang et al., 2010). In an expression array study (Wensman et al, submitted manuscript) performed on mouse mast cells exposed to tumor conditioned medium, the gene 4-1BB was among the most up-regulated genes compared to control medium. 4-1BB codes for a membrane receptor protein of the tumor necrosis factor superfamily and has been shown to be important in T cell regulation in tumor diseases. This study was performed to investigate if human mast cells up-regulate 4-1BB when they get exposed to tumor conditioned medium.
