1. Investigating the effect of grinding method on ore beneficiation behaviour
Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgiSammanfattning : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. LÄS MER
2. The impact of addition of force control agent in adhesive mixtures : Effect of magnesium stearates on flowability and aerosolization properties
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaceutisk biovetenskapSammanfattning : When drugs need to be delivered to the respiratory system dry powder inhalers (DPIs) are often used. The powders in DPIs often consists of a micronized active pharmaceutical ingredient (API) that is adhered to a larger carrier particle forming an adhesive mixture. LÄS MER
3. The effect of lactose fines, magnesium stearate, choice of mixer and mixing process on the performance of adhesive mixtures for inhalation
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : Dry powder inhaler (DPI) formulation is a major area of interest since they are employed by the healthcare system to treat relevant chronic diseases like asthma. Previous research has established that the manufacturing process and formulation composition are key for the active pharmaceutical ingredient to reach the lungs and achieve therapeutic effects.

4. Comparing different methods of measuring particle size for pharmaceutical excipients
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

5. LES modelling of spray combustion
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.
