Introduction. Infection Prevention is one of the surgical nurses' main responsibilities. One of the steps which patients undergo in this purpose before surgery is the preoperative skin desinfektion. Background. The patient washes the day before surgery with Descutan cutaneous sponge 4 %, a sponge containing chlorhexidine.

The main purposes of this study were to 1) quantify bacterial production in winter during ice conditions, and 2) to compare these production measures with values measured from summer and open water conditions in three humic lakes situated in northern Sweden. Another purpose of this study was to 3) examine whether clear-cutting significantly affected bacterial production or water chemistry in two lakes situated in catchments were a large part of the forest had been removed through logging compared to an undisturbed reference lake. In winter (March/April 2014), the bacterial production ranged from 0, 7 - 2, 2 µgC/L/day and in the summer of 2013 the production values was 4 ? 10 times higher. The main reason for lower bacterial production in winter was ascribed to lower water temperatures as well as to older and more recalcitrant DOC, as there were no significant differences in total dissolved nitrogen or DOC concentration or -quality, that could explain a lower production compared to summer.

The lily pad creatures arose out of my childhood memories of nature. This project has been an ongoing investigation of a workprocess as well as an exploration of my own sense of artistic idiom. I wanted to develop my knowledge in pattern design and focus on the artistic expression. I want the pattern to invite participation in storytelling in the same way that nature has inspired me..

The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores. In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied. Most bacteria need humidity and prefer a quite high water activity to be able to grow.

About 10 % of the adult women population in Sweden are treated annually for urinary tract infections. The increasing bacterial resistance towards antibiotics is classified by WHO (World Health Organization) and ECDC (European Centre for Disease Prevention and Control) as one of the greatest treats for human health in a global perspective. To find alternatives scientists are studying the possibility to use probiotics to reduce the frequency of recurring urinary tract infections. This literature study examines five randomized double blinded placebo controlled studies where different strains of Lactobacillus have been used as a prophylactic to women suffering from recurrent urinary tract infections and bacterial vaginosis. Overall the studies do not display enough promising results to recommend the use of probiotics as a prophylax or cure..

The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

Hommage till slit och släp is a tribute and a resarchabout patterns relation to clothes. The primary goalof the project was to examine how a pattern couldchange the apperance of a garment and how thegarment?s construction and material would impactthe pattern. The formative survey was about thesparsely populated areas in the north of Sweden andhow theese areas have been treated by the swedishgovernment. The issue worked as an inspiration andmethod which I used in the patternresearch.

This is a project about creating new patterns from childhood memories of patterns. I havebeen reaserching the possibility to add further value to a pattern in terms of memories, stories,associations and feelings.The goal has been to create new patterns from other peoples memories of patterns. It hasalso been my purpose to develop my skills and feel more comfortable in the creating of patterns.The questions at issu has been:How can I tell a story with a pattern?How can I communicate a feeling or a mood with a pattern?How does our memory image and an interpretation effect the process and the end result?I interviewed nine people. The questions during the interview was:Your name and age?Where was the pattern you?r going to talk about placed?How did it look like?What kind of feelings or emotions do you connect with this pattern?Someting else you whant to tell about the pattern?I created five patterns and during the process with the interviews I realised the importance ofshowing the stories in the end result.

The character of a pattern carries through to the context in which it is placed. Each pattern tells a story. By interpreting our surroundingenvironments we become inspired, and the patterns in turn can become part of our own narratives. This project was fuelled by my fascination and desire to explore patterns. My method of exploration was based on prior knowledge of patterns and interior design.The question became how can I apply my knowledge of interior design to pattern design and how could I best translate the brief intoa language of colour and shapes? The aim was to develop my knowledge of pattern design as well as to use this opportunity to combine my design methods with those of a professional designer.

My project aims to understand more about the methods used in making woven textiles on an industrial level, and how these tech¬niques can be adapted to create object-specific pieces. On visiting the furniture fair in Stockholm, I was surprised to see that most of the textiles used for furniture were so similar, despite the variation in the furniture itself. My project is about creating textile patterns that are specific for each piece.The idea behind the process could be used for any product, but the pattern I created is specifically for the armchair Accent by Yngve Ekström. I wanted to create the feeling of a pattern moving over the surface of the object and adjusting to it. I worked primarily with differences in density.

Sweden has a great tradition of pattern in both wallpapers and fabric, where colours and shape matters a lot for the customer. I have through my examination project tried to expand the views and find new alternatives and shapes for the obvious pattern traditions. I have therefore worked with what could be on the verge of attractive or repelling. To create a curiosity of what is considered to be commercial. From the prospective of the body organs I have created physical patterns for fabric and wallpapers.

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Ett mönster är uppbyggt av ett motiv som upprepas. Denna upprepning kan fortsätta i all oändlighet. Hållbar antyder långsiktighet. Mönstrets övergripande egenskap är oändlighet. Hur kan denna egenskap hos mönstret nyttjas inom mönsterdesign för att främja hållbar utveckling? Det här kandidatarbetet undersöker mönsterdesignens möjlighet att verka för hållbar utveckling genom att se till begreppet mönster ur ett bredare perspektiv, samt i relation till design för hållbar utveckling.

Under mina tre år på Konstfack har jag arbetat fram en värld av ickefigurativa mönster. I mitt examensarbete låter jag mönstren röra sig bortom skolans väggar och ut i det offentliga rummet. Genom att titta på hur reklamen idag tar plats i staden, på gator, väggar, tidningar och i kollektivtrafiken har jag hittat en för mig ny exponeringsyta.Mitt arbete består av två delar:I min processbeskrivning utforskar jag ickefigurativa mönsterbilders värde och roll i både konstnärliga och vetenskapliga sammanhang. Jag har också studerat hur reklamen tar plats i vårt offentliga rum. I mitt praktiska konstnärliga arbete har jag använt dessa teoretiska kunskaper tillsammans med en grupp tillvägagångssätt som jag gett samlingsnamnet PATTERN ATTACK.I mitt konstnärliga arbete presenterar jag hur olika PATTERN ATTACKs kan gå tillväga. .
