Studies of X-Ray Optics And Polarimetry For Synchrotron Radiation

Popular Abstract in English Among the large variety of experiments performed in science, a common one is to pass a light beam through a sample, the object to be studied, and to study the outcomes of the light-sample interaction. Many light sources have been used for this purpose, like light bulbs and lasers. A modern light source used nowadays is the so-called storage ring. In the storage rings elSynchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies have made possible to obtain very low emittance electron beams, which together with the use of undulators allow to guide a very high photon flux into a very small beam size required by the experiments. Development of sources has been accompanied with eq

Cystatin C and cathepsin B in human colon carcinoma: Expression in cell lines and matrix degradation

Expression of the cysteine proteinase cathepsin B and its physiological inhibitor cystatin C was analyzed in vitro in I human fibrosarcoma and 4 human colon carcinoma cell lines. Cystatin C antigen as well as cathepsin B activity were detected in the conditioned media of the 5 cell lines. The corresponding cell extracts expressed high levels of cathepsin B activity, whereas only trace amounts of c

Modeling the Impact of a Standardized Breakfast on T1DM Fasting Blood Glucose

The design of a controller for glycemia regulation, either in open or in closed-­‐loop, relies on models able to describe the effects of a meal intake and an insulin injection on blood glucose dynamics. The purpose of this study was therefore to propose a physiological relevant yet parsimonious model for carbohydrate action on fasting blood glucose in T1DM patients when no insulin is taken.

Philosophy of Interdisciplinarity: Problem‐Feeding, Conceptual Drift, and Methodological Migration

One way to bring order into the often muddled picture we have of interdisciplinarity is to sort interdisciplinary projects or aims by the kinds of element that interact in encounters between researchers of the two or more disciplines involved. This is not the usual approach. Since the early seventies and the publication of Erich Jantsch (1972), at least, the level of integration of the disciplines

Stereovision: A model of human stereopsis

A model of the human stereopsis mechanism is presented. As foundation for the model lies a number of ideas that has arisen from redefining the correspondence problem. Instead of establishing potential matches by the detection and matching of some set of "predefined" features, e.g. edges (zero-crossings) or bars (peaks/throughs), matches are sought by comparing the overall configuration of contrast
