1. 11. Core Biopsy of Breast and Axillary Lesions : Technical and Clinical Aspects

   Författare :Shahin Abdsaleh; PG Lindgren; Per Skaane; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Automatic core needle biopsy; Semiautomatic core needle biopsy; Surgical specimen; Dynamic needle behavior; Hormone Receptors; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Sammanfattning : The aims of this work were to image and analyze the needle behavior at automated core biopsy, to investigate the clinical utility of an alternative core biopsy technique using a semiautomated gun in breast and axillary lesions, and also to compare core biopsy with surgical specimens in malignant breast lesions regarding histologic features and hormone receptor expression.In two experimental studies, using butter and silicon phantoms, respectively, the needle pass was imaged and its dynamic behavior studied.

3. 12. Modeling of Cold Pilgering of Stainless Steel Tubes

   Författare :Yağız Azizoğlu; Lars-Erik Lindgren; Jonas Edberg; Per Gradin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold pilgering; finite element method; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Cold pilgering is a complex forming process used to produce seamless tubes in terms of modeling due to the complexity in kinematic of tools, friction condition and material behavior. The process development has mostly been based on simple formulas and costly full-scale tryouts. LÄS MER

4. 13. Deliberations on the impact of antibiotic contamination on dissemination of antibiotic resistance genes in aquatic environments

   Författare :Björn Berglund; Per-Eric Lindgren; Dan I. Andersson; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The great success of antibiotics in treating bacterial infectious diseases has been hampered by the increasing prevalence of antibiotic resistant bacteria. Not only does antibiotic resistance threaten to increase the difficulty in treating bacterial infectious diseases, but it could also make medical procedures such as routine surgery and organ transplantations very dangerous to perform.

5. 14. Antibiotic Resistance in Wastewater : Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

   Författare :Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; Microbiology; Mikrobiologi;

   Sammanfattning : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. LÄS MER

7. 15. Skolmusikalen : om möten, makt och musik i två skolmusikalprojekt i årskurs nio

   Författare :Lorentz Edberg; Per-Olof Erixon; Erik Sigurdson; Monica Lindgren; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Educational tradition; local community; pedagogical code; recontextualisation; school musical; pedagogiskt arbete; educational work;

   Sammanfattning : The two school musical theatre projects in this case study were carried out in 2011-2012 in Year 9 at two Swedish secondary schools, Annebäckskolan and Bäråskolan, as a part of the subject “Elevens val” (Student’s Elective). The purpose of the study was to analyse how pedagogy, power and control appeared in the projects, based on the following research questions: How can the influence of the local community and leisure discourses on education be understood through the two school musical theatre projects? What pedagogical codes appear in the projects and how do they relate to time and space? What power relations are produced and why? The study was conducted through participatory observations and interviews and dialogues with participating students and teachers. LÄS MER
