  1. 16. Influence of hydrogen and carbides on high temperature cracking in cast Inconel

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gunnar Dufwa; [2022]
    Keywords : Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

    Abstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE

  3. 17. Hur påverkas bakbenets temperatur, omkrets och diameter av olika typer av bandageunderlägg?

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Matilda Hägglöf; [2022]
    Keywords : bandageunderlägg; kotsenskida; kotled; temperatur; diameter; omkrets;

    Abstract : Tidigare studier visar att ledproblem var ett vanligt förekommande problem hos sporthästar. En av dessa ledproblem som hästen kan lida av är svullnader i lederna på hästens ben. En svullnad i hästens leder kan uppkomma på grund av ökad ledvätska i leden och det är den typen av svullnad som med talspråk ofta kallas för galla. READ MORE

  4. 18. Evaluation of the LPJ-GUESS crop model under ambient and elevated CO2 concentrations.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Annika Nitschke; [2022]
    Keywords : LPJ-GUESS; free-air carbon dioxide enrichment experiments; elevated CO2; climate change; wheat yield; Earth and Environmental Sciences;

    Abstract : In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. READ MORE

  5. 19. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Skoog; [2022]
    Keywords : Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

    Abstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

  6. 20. Impact on dissolution rate of oral solid dosage forms by increasing the temperature and paddle speed with fully automated dissolution robot SingBATH

    University essay from Uppsala universitet/Institutionen för farmaci

    Author : Hamad Hamid; [2022]
    Keywords : SingBATH; Fully automated dissolution robot; dissolution rate; temperature; RPM of paddle;

    Abstract : The pharmaceutical dosage forms usually undergo a test which is intended for assessing in-vitro performance called the dissolution test. Apart from the drug formulation, factors which can affect dissolution rate include revolutions per minute (RPM) of paddle, temperature of the system and cloud point of the excipients. READ MORE
