Centromeres have not yet been functionally defined in higher eu- karyotes, largely due to the huge amounts of repeated DNA in these regions of most species and difficulties of delimiting centromeric from pericentric regions. Also the latter have large quantities of mostly noncoding DNA, expressed cytologically as pericentric heterochromatin. The dipteran Chironomus pallidivittatus is advantageous

The aim of the present investigation was to elucidate possible effects of cystatin C on inflammatory responses mediated by macrophages. Previously it has been shown that in vitro treatment of murine peritoneal macrophages with interferon-gamma (IFN-gamma) causes a down-regulation of cystatin C secretion. To investigate whether such changes in cystatin C expression in turn can affect inflammatory r

Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. The aim of this thesis was to develop eff

Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface, i.e., the radome, is analyzed. The transformation is based on the surface integral representation that relates the equivalent currents to t

”Sökandet är vårt största äventyr”, konstaterar Rolf Edberg. Följ med på ett sådant äventyr och upplev något av samma glädje, klarhet och insikt som en sådan upptäcktsresa under 50 år har gett mig! Resan, vägen, berättelsen börjar med ”läsning” av romaner och går via begrundanden av litteraturvetenskap, humaniora och naturvetenskap till upptäckten av en ”humanistisk” naturvetenskap, en ”världsfi

Consumer goods can be delivered in a number of different ways. One important and very interesting method is the use of e-commerce to deliver the groceries to the consumer. Distribution of consumer goods, especially groceries, poses a number of challenges to the use of e-commerce. Challenges that must be solved in order to find a justified solution. This paper will present and discuss a new researc

Results from experiments on laboratory scale fedbatch processes are presented as well as analysis and design of the control system. The main reason for control is to track the drastic growth in feed demand during a cultivation. Variations in the amount and quality of the inocculum makes precalculated dosage schemes of limited value to obtain reproducible cultivation conditions. Two processes have
