  1. 1. Surface Roughness Considerations in Design for Additive Manufacturing: A Space Industry Case Study

    Författare :Didunoluwa Obilanade; Peter Törlind; Christo Dordlofva; Anna Rönnbäck Öhrwall; Marta-Lena Antti; Stankovic Tino; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Space Industry; Surface Roughness; Design for Additive Manufacturing; DfAM; Laser Powder Bed Fusion; Produktinnovation; Product Innovation;

    Sammanfattning : Additive Manufacturing (AM), commonly known as 3D printing, represents manufacturing technology that creates objects layer by layer based on 3D model data. AM technologies have capabilities that provide engineers with new design opportunities outside the constraints of traditional subtractive manufacturing. LÄS MER

  3. 2. The incurable cancer patient at the end of life : Medical care utilization, quality of life and the additive analgesic effect of paracetamol in concurrent morphine therapy

    Författare :Bertil Axelsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Palliative; cancer; place of death; health care utilization; quality of life; morphine; paracetamol; pain; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Only 12% of the patients died at home. When the period between diagnosis and death was less than one month, every patient died in an institution. Younger patients, marriedpatients, and those living within the 40 km radius of the hospital utilized more hospital days. LÄS MER

  4. 3. Sintering simulation framework for 316L stainless steel components manufactured by binder jetting

    Författare :Alberto Cabo Rios; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; sintering modelling; additive manufacturing; binder jetting; stainless steel.; dilatometry;

    Sammanfattning : Binder Jetting (BJT) is an additive manufacturing (AM) technology allowing mass-production of small to medium-size metal components. BJT is a multi-step AM technology, where the geometrical shape of components is provided during the printing step, and the final properties are achieved through a second consolidation step - sintering.

  5. 4. Occurrence and ecotoxicity of endocrine disruptor chemicals in aquatic environment and sewage treatment systems

    Författare :Andre Luis de Sa Salomao; Marcia Marques; Paulo Sergio Martins Carvalho; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrine disruption; Alkali-labile phosphate; Estrogen hormones; Oreochromis niloticus; Unicellular green microalgae; Additive effect; Less-than additive effect; Chronic toxicity; Natural Science; Naturvetenskap;

    Sammanfattning : The applicability of one selected method for indirect measurement of vitellogenin (Vtg) in fish plasma based on the quantification of alkali-labile phosphates (ALP method) to assess estrogenicity in water was investigated. The ALP method applied in this investigation was originally developed with Carassius carassius (Crucian carps). LÄS MER

  7. 5. Epidemiological studies of the social context of illness and sickness

    Författare :Nelson Blank; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Reported morbidity; illness; health inequalities; self-rated health; health status; social class; ;

    Sammanfattning : The overall objective of this thesis is to contribute to the theoretical and methodological development of research aiming to explain diversity in experiences of illness and sickness. Special attention is paid to the relationships between objective life conditions, personal circumstances and perceptions of well-being. LÄS MER
