  1. 1. Optimizing Sample Dissolution Methods of Low Water Soluble Intermediate Organic Compounds to Support Environmental Risk Assessment during Active Pharmaceutical Ingredient Manufacturing.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Warda Mohammed; [2021]
    Keywords : Active pharmaceutical ingredient; API; total organic content; TOC; chemical oxygen demand COD; biological oxygen demand; BOD; Microtox; octanol-water partition coefficient; Kow; solubility.;

    Abstract : This project focus on investigating the dissolution of low water-soluble intermediate organic compounds called active pharmaceutical ingredients (API) and organic substances that are manufactured by a pharmaceutical company, Cambrex Karlskoga in Sweden. Several dissolution methods were used and evaluated using methods including total organic carbon (TOC), chemical oxygen demand (COD), biochemical oxygen demand (BOD) and Microtox toxicity test.

  3. 2. Understanding the effect of temperature and time on Gamma prime coarsening for Nickel-base superalloy Haynes 282

    University essay from KTH/Materialvetenskap

    Author : Kevin Vattappara; [2019]
    Keywords : Haynes 282; gamma prime 𝛾′ ; Arc-heat treatment; COMSOL modelling; isothermal transformation; coarsening; Thermo-Calc simulations;

    Abstract : Haynes 282 is a gamma prime (𝛾′)-strengthened nickel base superalloy developed in 2005, exhibiting a good combination of high temperature properties and fabricability. Microstructural features such as 𝛾′ and carbides play an important role in deriving the mechanical properties of the alloy during heat treatment. READ MORE

  4. 3. Influence of bio-coal ash respectively coal structure on coke production and coke quality

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Frida Bäck; [2019]
    Keywords : Bio-coke; bio-coal; leaching; coke quality; carbon structures; torrefied sawdust;

    Abstract : In recent years, the consequences of global warming have increased the discussion about the climate impact caused by humans and the fossil emissions. Sweden has decided to reduce the negative climate impact with a zero vision for the fossil carbon dioxide emissions in year 2045. READ MORE

  5. 4. Linguliform Brachiopods from the Middle Cambrian ‘Thick’ Stephen Formation at Odaray Mountain, Canadian Rocky Mountains

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sara Saxén; [2015]
    Keywords : Brachiopoda; Lingulida; Middle Cambrian; Stephen Formation; new species; Brachiopoda; Lingulida; Mellersta kambrium; Stephenformationen; ny art;

    Abstract : The linguliform brachiopod fauna from the Stephen Formation have long been thought to be very species poor and only consist of a few genera, but new discoveries from lime-stone beds in the “thick” Stephen Formation shows that this is not the case. The species described herein, Kyrshabaktella cf. tatjanae and Ceratreta hansi sp. nov. READ MORE

  6. 5. Erosion during Brazing in Stainless Steel grade 304

    University essay from KTH/Materialvetenskap

    Author : Nabeel jahanzeb; [2012]
    Keywords : Erosion; dissolution of base; filler metal; Wettability; oxygen partial pressure; high vacuum; SEM analysis.;

    Abstract : The erosion or dissolution of stainless steel grade 304 as base metal by molten brazing fillermetal was investigated using one nickel and two iron based filler metals. The difference betweentwo iron filler metal is 5 % Manganese content in one of the filler metal. READ MORE
