Konstmusik i stereo : Hur väl återger olika stereotekniker den verkliga upplevelsen i konsertlokalen?

Examensarbetet undersöker vilken stereoteknik som uppfattas ge den mest verklighetstrogna återgivningen av konstmusik samt om valet av stereoteknik påverkas av ljudteknisk eller konstmusikalisk bakgrund. Undersökningen gjordes i form av ett lyssningstest där deltagare i tre grupper fick, efter att ha lyssnat till en konstmusikalisk ensemble live i en konsertlokal, lyssna till tio olika inspelningar av samma stycke vars enda skillnad var vilken stereoteknik som använts vid inspelningen. Deltagarna ombads att gradera hur väl inspelningarna speglade verkligheten samt rangordna dem efter vilka de ansåg låta bäst oavsett hur trogna verkligheten de var.Studiens resultat visar på att konstmusikalisk och ljudteknisk bakgrund påverkar valet av vilken stereoteknik man föredrar och vilken man tycker låter mest likt den verkliga upplevelsen av musiken live. Av resultatet kan man också utläsa att personer inte konsekvent anser att de inspelningar som låter mest verklighetstroget är den man anser låter bäst.

3D roll-forming of hat-profile with variable depth and width

The use of roll-formed products in automotive, furniture, buildings etc. increases every year due to the low part-production cost and the complicated cross-sections that can be produced. The limitation with roll-forming until recent years is that one could only produce profiles with a constant cross-section in the longitudinal direction. About eight years ago ORTIC AB [1] developed a machine in which it was possible to produce profiles with a variable width (“3D roll-forming”) for the building industry. Experimental equipment was recently built for research and prototyping of profiles with variable cross-section in both width and depth for the automotive industry. The objective with the current study is to investigate the new tooling concept that makes it possible to roll-form hat-profiles, made of ultra high strength steel, with variable cross-section in depth and width. The result shows that it is possible to produce 3D roll-formed profiles with close tolerances.

Medical students are afraid to include abortion in their future practices : in-depth interviews in Maharastra, India

BACKGROUND: Unsafe abortions are estimated to cause eight per-cent of maternal mortality in India. Lack of providers, especially in rural areas, is one reason unsafe abortions take place despite decades of legal abortion. Education and training in reproductive health services has been shown to influence attitudes and increase chances that medical students will provide abortion care services in their future practice. To further explore previous findings about poor attitudes toward abortion among medical students in Maharastra, India, we conducted in-depth interviews with medical students in their final year of education. METHOD: We used a qualitative design conducting in-depth interviews with twenty-three medical students in Maharastra applying a topic guide. Data was organized using thematic analysis with an inductive approach. RESULTS: The participants described a fear to provide abortion in their future practice. They lacked understanding of the law and confused the legal regulation of abortion with the law governing gender biased sex selection, and concluded that abortion is illegal in Maharastra. The interviewed medical students' attitudes were supported by their experiences and perceptions from the clinical setting as well as traditions and norms in society. Medical abortion using mifepristone and misoprostol was believed to be unsafe and prohibited in Maharastra. The students perceived that nurse-midwives were knowledgeable in Sexual and Reproductive Health and many found that they could be trained to perform abortions in the future. CONCLUSIONS: To increase chances that medical students in Maharastra will perform abortion care services in their future practice, it is important to strengthen their confidence and knowledge through improved medical education including value clarification and clinical training.
