  1. 21. Phenotypic adaptation in early bacterial colonizers on oral surfaces - an in vitro study

    University essay from Malmö högskola/Odontologiska fakulteten (OD)

    Author : Sylvia Hunfjörd; Jenny Olsson; [2016]
    Keywords : Proteolytic activity; Early colonizers;

    Abstract : Orala bakterier, såsom de tidiga kolonisatörerna; Streptococcus gordonii, Streptococcus oralis, Streptococcus mitis och Actinomyces naeslundii uttrycker ett brett spektrum av ytadhesiner som möjliggör inbindning till receptorer i tandpellikeln. Saliv, gingivalt exudat (GCF) och kollagen I i cement på blottade rotytor erbjuder möjliga ytor i munhålan där bakterier kan adherera och bilda biofilm. READ MORE

  3. 22. Development of Wet Electrostatic Precipitator for Generation of Nanoparticle-Protein Solution

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Julia Adner; [2015]
    Keywords : WESP; Nanoparticle; bioligical identity; protein solution; Technology and Engineering;

    Abstract : To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. READ MORE

  4. 23. Study of CVD deposited i-ZnO layers in CIGS thin film solar cells

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Fredrik Larsson; [2015]
    Keywords : CVD; CIGS; intrinsic; ZnO; thin film; solar cell;

    Abstract : CIGS thin film solar cells usually include a thin layer of intrinsic zinc oxide (i-ZnO) deposited on a CdS buffer layer by sputtering. However an interest has grown in using chemical vapor deposition (CVD) instead. READ MORE

  5. 24. The impact of waste handling on small-scale farming in Malawi

    University essay from SLU/Dept. of Soil and Environment

    Author : Sabina Braun; [2015]
    Keywords : soil management; poverty; land use; fertilisers; agriculture; food security;

    Abstract : This study assess the impact of human waste and household garbage on the concentrations of heavy metals in arable land on two sites located close either to a waste collecting point (WD) or waste water treatment plant (WWTP). Malawi suffers from poverty, low food security and problems with access to land. READ MORE

  6. 25. Biofilm in urinary catheters : impacts on health care and methods for quantification

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Gustaf Lönn; Edvin Kalmaru; [2014]
    Keywords : Biofilm; methods for quantification; urinary catheters; catheter assosiated urinary tract infections;

    Abstract : Biofilm is an increasing problem in the healthcare and have in urinary catheters long been associated with nosocomial urinary tract infections. The infections caused in 2002 alone 13,000 deaths in the US and annual costs have been estimated to over $400 million. These costs are however most likely underestimated. READ MORE
