1	<b>Investigating application methods and active agents for healthcare-related surface contamination</b> Geraldine Madalitso Tembo (9754958) 19 July 2024 (has links) <p dir="ltr">Healthcare-acquired infections (HAIs) cause a burden in acute care hospitals in the United States. HAIs are caused by <i>Staphylococcus aureus</i>, along with other pathogens found on high-touch and non-high-touch surfaces in hospital environments (e.g., bed rails, blood pressure cuffs, countertops, and floors). To minimize the growth and cross-contamination of pathogens, it is vital to use disinfectants for surface decontamination. In this work, the impact of different application methods and disinfectant active agents was evaluated for use on different healthcare-related surfaces. The first study examined the cross-contamination potential of an auto-scrubber when used to clean and disinfect a 2m<sup>2</sup> vinyl floor contaminated with <i>S. aureus</i>. Five EPA-registered disinfectants and a cleaner were used with three application methods. Hydrogen peroxide and quaternary ammonium compounds-based disinfectants significantly resulted in less cross-contamination compared to the cleaner. However, there were no significant differences among the application methods used. In the second study, manual floor cleaning and disinfecting on a two-square-meter vinyl floor with three different moping materials were evaluated to assess their ability to prevent cross-contamination. Evidence showed that there were significant differences among the products used, with Hydrogen peroxide and quaternary ammonium compound products being the most effective. The cleaner caused the most cross-contamination, while cotton mops resulted in significant cross-contamination among materials used. Study three investigated the differences among four application methods used with three different wiping cloths (Cotton, microfiber, and nonwoven) on a 2m<sup>2</sup> Formica board. A spray surface and wipe method was successful in decreasing <i>S. aureus</i> on the surface. A hydrogen peroxide-based product was most effective in reducing bacteria at contamination areas and minimizing cross-contamination. Microfiber cloth picked up significantly more bacteria at contaminated areas. Post disinfection, there was evidence of cross-contamination at sampling areas regardless of product type, wiping cloth, and application methods used, with the cotton cloth causing the most cross-contamination. Viable bacteria were found on the wiping cloths used and on worker's gloves. Together, this work shows that the use of disinfectants is important in hospital environments. The choice of product, wiping material, and application method are principal in the disinfection process as they influence disinfection failure or success.</p> healthcare acquired infections Staphylococcus aureus Auto-scrubber Mopping Disinfectants Disinfectant wipes Floor disinfection Application methods
2	I like it dirty Pontén, Stina January 2018 (has links) Using dirt and cleaning as a point of departure, I have examined how categorization and intentionality affects our perception of value. The work is partly performative in its nature where this performativity sets the limelight on the transition between categories: From dirt to craft, from irrational behaviour to art. In the artistic process, I have used coffee rings on table cloths, shoeprints on wallpapers and the act of mopping as a means of questioning. Through this, I also reveal and question hierarchies in society. The essay discusses and theoretically relates to the artistic work. / Med utgångspunkt i smuts har jag underökt hur kategorisering och intentionalitet påverkar vår uppfattning av värde. Arbetet är delvis performativt till sin natur, där denna performativitet sätter fokus på övergången från en kategori till en annan: Från smuts till konsthantverk, från irrationellt beteende till konst. I den konstnärliga processen har jag använt mig av kafferingar på dukar, skoavtryck på tapeter och moppande av golv som medel för ifrågasättande. PÅ detta vis blottlägger och ifrågasätter jag hierarkier i samhället. I uppsatsen diskuterar jag och relaterar teoretiskt till det konstnärliga arbetet. hierarchies dirt filth categorization intentionality performativity value art craft society art jewellery art jewelry corpus cleaning tidying domestic work mopping mop coffee stains coffee rings shoe prints hierarkier smuts kategorier intentionalitet performativitet värde konst konsthantverk samhälle smyckekonst korpus städning mopp kafferingar skoavtryck Arts Konst
