  1. 1. Investigation of Factors Affecting the Emulsification of Skin Creams

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Linnéa Bodell; [2019]
    Nyckelord :Emulsion; Homogenizer; Skin Cream; Factorial Experiment;

    Sammanfattning : Skin creams are one of Sky Resources key products, they are produced as an oil-in-water(O/W) emulsion. In order to form an emulsion the oil and water needs to be able to mixtogether, for that to happen the oil and water droplets have to be broken up into very smalldroplets (colloids). LÄS MER

  3. 2. Metal Fractionation in Snowmelt Runoff : A Comparison between Ultrafiltration and Diffusive Gradients in Thin Films (DGT) techniques

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Sarah Lindfors; [2017]
    Nyckelord :Urban Runoff; Metals; Ultrafiltration; Diffusive Gradients in Thin Films;

    Sammanfattning : Urban runoff is a non-point pollution source deteriorating water quality of natural watersystems. The composition of urban runoff vary depending on land use, seasonal changes anddifferent surfaces that come into contact with the water. LÄS MER

  4. 3. Synthesis and characterization of amine-functionalized microgel particles and their subsequent assembly into colloidal molecule-like clusters by droplet-based microfluidics

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Emil Gustafsson; [2015]
    Nyckelord :Physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : The ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subsequent assembly into clusters using droplet-based microfluidics, with the goal of forming responsive colloidal molecules with well-defined valency.

  5. 4. Prehospital vätskebehandling vid stort trauma ur en sjuksköterskas perspektiv : En systematisk litteraturstudie

    Kandidat-uppsats, Institutionen för folkhälso- och vårdvetenskap

    Författare :Thomas Hörger; Andreas Törning; [2012]
    Nyckelord :Trauma; vätskebehandling; kolloider; prehospital vård; omvårdnad;

    Sammanfattning : The aim of this study was to determine which type of fluid to use in trauma care to improve patient survival. The method used was a systematic review, where a total of 18 studies were reviewed and 13 included in the results. LÄS MER

  7. 5. Bedömning av spermiemotilitet i färsk, kyld samt selekterad hingstsperma med Qualisperm

    L3-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Hanna Strutz; [2007]
    Nyckelord :Qualisperm; hingstsperma; motilitet;

    Sammanfattning : This EEF-project is a part of a larger project at SLU, Division of Reproduction, Dept of Clinical Science, with the intention of developing and evaluating new methods for the assessment of stallion semen quality. Over the last 10 years there has been an increase in the use of artificial insemination with cooled semen in Swedish horse breeding. LÄS MER
