  1. 1. Determination of Mass- and Heat Transfer Coefficients for Computer Modelling of Pharmaceutical Freeze-Drying

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Linnea Gustafsson; [2021]
    Keywords : Freeze-drying; Mass- and Heat Transfer; Pharmaceutical production; Simulation; MATLAB; Pharmaceutical technology; Technology and Engineering;

    Abstract : This thesis work deals with the determination of mass- and heat transfer coefficients for pharmaceutical vial freeze-drying and the one-dimensional steady state computer modelling of primary drying. The overall heat transfer coefficient K_V for the vial/freeze-dryer system was successfully determined using a gravimetric method. READ MORE

  3. 2. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Christina Andersen; [2020]
    Keywords : alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. READ MORE

  4. 3. Understanding product build up at packaging material surface to address food waste

    University essay from Lunds universitet/Förpackningslogistik

    Author : Ashri Nugrahini; Sonam Lhamo; [2019]
    Keywords : Yoghurt; Packaging material; Build up; Yield stress; Gravimetric dip test; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : Difficulty to empty the package is one of the main reason of food waste in yoghurt at consumer level with an estimated 5-10% of product residue being left on the packaging material. The phenomenon of product build up is explained by numerous hypothesis. However, these studies are empirical in nature. READ MORE

  5. 4. Oxidation of Graphite and Metallurgical Coke : A Numerical Study with an Experimental Approach

    University essay from KTH/Materialvetenskap

    Author : Yousef Ahmad; [2016]
    Keywords : Graphite oxidation rate; CFD; Dynamic coupling; Fluent; TGA;

    Abstract : At the royal institute of technology (KTH) in the department of applied process metallurgy, a novel modelling approach has been developed which allows a dynamic coupling between the commercial thermodynamic software Thermo-Calc and the commercial computational fluid dynamic (CFD) software Ansys Fluent, only referred to as Fluent in the study. The dynamic coupling approach is used to provide numerical CFD-models with thermodynamic data for the thermo-physical properties and for the fluid-fluid chemical reactions occurring in metallurgical processes.

  6. 5. Quantification of Hyperhidrosis using Electronic Sudometer

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

    Author : SYED GHUFRAN KHALID; [2013]
    Keywords : Electronic Sudometer; Hyperhidrosis;

    Abstract : Human skin has various pathologies in the form of acute and chronic diseases. Some are only cosmetic diseases which are not harmful for life but they can affect mental health and disrupt daily activities. Hyperhidrosis is one of these cosmetic diseases which may be caused by diabetes, infections, or thyroid hyper activity, or can be inherited. READ MORE
