Utvärdering av mikrobiologiska provtagningsmetoder inom ölbryggningsprocessen :

The aim of this study was to establish knowledge about the most suitable substrate for cultivating different kinds of anaerobic beer spoilage bacteria in the brewing industry. During the study, two other aspects were investigated; if the sample volume affects the results and which anaerobic beer spoilage bacteria are present in the micro flora at the brewery. The method used was standard cultivation with four different substrates; Universal Beer Agar, Nachweismedium Bierschädliche Bakterien, Raka Ray and VLB S7-S. During the identification of bacteria in the micro flora, a method using PCR was used. None of the substrates showed a significant advantage over the others.

Digitalisera loggboken : En analys av utmaningarna med att utveckla IT-stöd för kunskapsintensiva verksamheter

Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.

Homosexualitet i tre klassifikationssystem under tre decennier: Ett queerteoretiskt perspektiv på SAB, UDK och DDC.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

Hur är det att leva med ADHD? Tankar och funderingar från ungdomar

The purpose of this study was to examine young persons' experiences of life with ADHD. Semi structured interviews were done with four boys age 14-18 years, diagnosed with ADHD. The interviews followed a guide that consisted of themes with questions. The themes examined were: diagnosis, school, home, social and personal issues and how these themes are connected to ADHD. The results indicate that it is hard to live with ADHD.

Säker läkemedelshantering - Faktorer som påverkar sjuksköterskan

Läkemedelshanteringen är ett av sjuksköterskans ansvarsområden inom hälso- och sjukvården. Utifrån kunskap och lagar skall den bedrivas på ett patientsäkert sätt men trots det sker läkemedelshanteringsfel vilket innebär risker i patientsäkerheten.Syftet med studien var att beskriva faktorer som påverkar säkerheten i samband med sjuksköterskans läkemedelshantering. Studien genomfördes som en litteraturstudie. Resultatet visade att vanliga läkemedelshanteringsfel är utebliven dos, fel administreringstid, fel dos, fel administreringssätt, fel läkemedel och läkemedel till fel patient. Faktorer som påverkar sjuksköterskans läkemedelshantering är felaktiga och dåligt skrivna läkemedelsordinationer, distraktion under läkemedelshanteringen, bristande rutiner samt införande av ny teknologi.

Matematisk kommunikation : i förskolebarns bygglek

Jag har undersökt vilken matematisk kommunikation som förekommer i förskolebarnets bygglek. Jag valde metoden videoinspelning där jag observerade fem olika bygglekssituationer som jag sedan tolkade och analyserade. För att få en större förståelse kring byggmiljön ställde jag också några frågor till pedagoger som ansvarade för konstruktionsverkstaden. Resultatet visade att det konkreta materialet förstärkte översättningsledet från det barnet redan kan (första ordningens språk) till det barnet ännu inte förstår (andra ordningens språk). Pedagogerna kunde med materialets hjälp göra ett matematiskt begrepp konkretare.

Elevperspektiv på laborativt material, en studie om hur laborativt material används i årskurs 6. Students perspective on laboratory material, a study about laboratory materials used in sixth grade

En studie om det laborativa materialet i bråkundervisningen utifrån elevernas perspektiv Författare: Ruzica Pajic Syftet med denna studie är att uppnå en djupare förståelse om det laborativa materialets betydelse i skolans matematik. I detta magisterarbete har det undersökts hur barns perspektiv påverkas i årskurs 6 utifrån hur laborativt material används i matematikundervisningen. I tidigare forskning redovisas barns lärande och hur den skildras utifrån kognitiva, kulturhistoriska och sociokulturella perspektiv. Bland dessa perspektiv presenteras och jämförs teoretikerna; Vygotsky och Bruner med varandra. Dessa teoretiker har valts, eftersom de presenterar grunderna för användning av laborativt material i skolan.

Motiverande samtal som metod för ökad närvaro i gymnasieskolan?

Effektiviteten av manualiserad Motivational Interviewing prövades i en experimentell design. Gymnasieelever med hög frånvaro (n=89) blockrandomiserades till antingen två sessioner Motivational Interviewing eller någon av de två kontrollgrupperna, som erhöll validerande samtal respektive ingen intervention. Den beroende variabeln utgjordes av förändring i frånvaro som rapporterades av de deltagande skolorna. Utöver detta användes School Refusal Assessment Scale för att undersöka orsaker till frånvaron. University of Rhode Island Change Assessment användes för att mäta motivation enligt Prochaska och DiClementes förändringsmodell.

Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

Double integrating spheres: A method for assessment of optical properties of biological tissues

The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

Akutvårdsavdelning och intensivvårdsavdelning - utformning, arbetsuppgifter och vad behöver finnas på plats?

Animals can be ill and need veterinary care for many reasons. The conditions can be more or less emergent, some can even be life-threatening. When an animal is in a life-threatening condition you can save the animals life just by having the right equipment near-by and ready to be used. This literature-study help you, as an active working veterinary nurse, with which these conditions are that can show up in your emergency ward and what you should have near-by to give animals with acute life-threatening conditions the care they need. The author also looked at work tasks at the emergency ward and found out that in Sweden it is not defined who can and/or should execute them. Interviews were also done with nine of the largest small-animal hospitals in Sweden to compare the studies found with the Swedish emergency wards.

Gymnasieelever och bråkräkning

For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).
