  1. 6. Process-induced disorder of pharmaceutical materials : Mechanisms and quantification of disorder

    Författare :Samaneh Pazesh; Göran Alderborn; Jonas Berggren; Niklas Sandler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Milling; Comminution; Powder flow; Amorphisation; Raman spectroscopy; Atomic force microscopy; Plastic stiffness; Elastic stiffness; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : One of the most important prerequisites in the drug development is to attain a reproducible and robust product in terms of its nature, and its chemical and physical properties. This can be challenging, since the crystalline form of drugs and excipients can be directly transformed into the amorphous one during normal pharmaceutical processing, referred to as process-induced amorphisation or process-induced disorder.

  2. 7. Analysis of Structural Dynamic Properties and Active Vibration Control Concerning Machine Tools and a Turbine Application

    Författare :Henrik Åkesson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Structural dynamics; Nonlinearities; Turning; Milling;

    Sammanfattning : Vibration in metal cutting is a common problem in the manufacturing industry, especially when long and slender tool holders or boring bars are involved in the manufacturing process. Vibration has a detrimental effect on machining. In particular the surface finish is likely to suffer, but tool life is also most likely to be reduced. LÄS MER

  3. 8. Sensory Quality and Consumer Perception of Wheat Bread : Towards Sustainable Production and Consumption. Effects of Farming System, Year, Technology, Information and Values

    Författare :Iwona Kihlberg; Einar Risvik; Lisbeth Johansson; Stefan Sahlstrøm; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Domestic sciences; Product quality; Production quality; Sustainability; Organic farming; Wheat; Organic Food; Bread; Milling; Breadmaking; Sensory analysis; Consumers; Information; Values; Food acceptance; Hushållsvetenskap; Domestic science and nutrition; Hushålls- och kostvetenskap;

    Sammanfattning : In order to study the effect of production systems aimed at sustainability on product quality and of sensory and non-sensory factors on product acceptance – the effect of farming system, year, milling and baking techniques on the sensory qualities of wheat bread as a model product was investigated using a descriptive test, and the effect of information and values on liking of bread using consumer tests.Whole wheat and white breads were baked with wheat grown in six lots in established conventional and organic farming systems in field trails, in two subsequent years for the white bread.

  4. 9. Controlling the dynamic characteristics of machining systems through consciously designed joint interfaces

    Författare :Constantinos Frangoudis; Cornel Mihai Nicolescu; Amir Rashid; Bulent Tasdelent; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production; machine tool; machining system control; joint interfaces; JIM; stiffness; damping; vibrations; machining process; milling; turning; deflections; accuracy; dynamic response;

    Sammanfattning : The precision of machining systems is ever increasing in order to keep up with components’ accuracy requirements. At the same time product variants areincreasing and order quantities are decreasing, which introduces high demands on the capability of machining systems. LÄS MER

  5. 10. Condition Monitoring in Machining Using Internal Sensor Signals

    Författare :Jari Repo; Cornel Mihai Nicolescu; Terje Lien; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condition monitoring; machine tool; machining process; milling; position encoders; tool wear detection; signal analysis; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and to achieve a more robust machining process. Any failure in the machining process and machine tool components may have negative effects on the final produced part. LÄS MER
