Analys av och förslag till utveckning av BIMM60 - Examensarbete på masternivå i biomedicin

Jag har analyserat det konstruktiva sambandet i kursen BIMM60 – examensarbete på masternivå i biomedicin. Kursen är den i sista kursen inom masterutbildningen. Eftersom alla biomedicinstudenter enligt utbildningsplanen även går BIMK30 - examensarbete på kandidatnivå i biomedicin är det viktigt att även beakta progressionen mellan dessa kurser. Jag fann en del brister i det konstruktiva sambandet m

Modeling for Optimal PID Design

Even though PID controllers have been around for a long time, few industrial controllers use derivative action and the remaining PI controllers are often designed with formula-based tuning rules rather than through computer-based optimization. This paper will delve into some of the reasons behind these choices and show potential benefits of instead using software-based PID tuning. Three commonly u

Beyond the Privileged Status of Written Discourse: Visual representation as a research tool

Essential to this paper is the recognition of the "privileged status our culture accords written discourse", which is discussed against the background of "the variety of ways in which we represent our realities" (Chaplin, 1994, p. 277), the power of representations to influence perceptions (Jacob, 1989) and the ever-growing importance of communities of shared meaning (Delanty, 2002). Jenks' argume

Mircostructure and rheological properties of concentrated tomato suspensions during processing

Food processing comprises operations such as dilution (changing the concentration), homogenisation (changing the particle size), and subsequent pumping (shearing), among others. It is thus of great interest to gain a better understanding of the mechanisms governing the creation and disruption of structures during these engineering operations, and the way in which they are related to the textural a

Experimental Colonic Obstruction Increases Collagen Degradation by Matrix Metalloproteinases in the Bowel Wall.

PURPOSE: Emergency resections for colonic obstruction are accompanied with increased risk of anastomotic dehiscence. Elevated local degradation of submucosal collagens by matrix metalloproteinases may predispose to anastomotic leakage. This study was designed to study the effect of colon obstruction and surgical trauma on matrix metalloproteinase activities and correlate these results to collagen

Lost and found: the enigmatic large-billed reed warbler Acrocephalus orinus rediscovered after 139 years

We present compelling evidence of the continued existence of the large-billed reed warbler Acrocephalus orinus, hitherto known only from the unique type specimen collected in NW India 139 years ago. Morphological and genetic analyses of an unusual Acrocephalus warbler mist-netted south-west of Bangkok, Thailand, on 27 March 2006, confirmed its identity as A. orinus, and revealed that it was hetero
