Isolation of human complement factors C3, C5 and H

An improved method for simultaneous purification of complement factors C3, C5 and H from human plasma has been developed. Using an initial batch separation technique with QAE-Sephadex, followed by chromatography on SP-Sephadex and gel filtration in Sephadex G-200, 600 mg of highly pure C3 can be prepared from 1600 ml of plasma. Simultaneously about 70 mg of highly pure factor H and 30 mg of C5 are

The informational foundation of the act

This paper presents a theory to quantify the informational value of human acts. We argue that living is functioning against entropy. Acting is presented as a set of decisions and choices to create order that we use as the foundation to develop the concept of complexity of human acts. Frequency theory of probability is then applied to characterize human acts in terms of their degree of freedom and

Biblioteket vid Campus Helsingborg, Lunds universitet

Arbetsbyte för kompetensutveckling är en metod som ofta diskuteras men som verkar svår att genomföra i praktiken. Projektbidrag från Helsingborgs kommun gjorde det möjligt för Helsingborgs stadsbibliotek och Campus Helsingborgs bibliotek att pröva arbetsbyte för elva medarbetare under vintern 2008 – 2009. Detta paper bygger till stor del på de korta rapporter som projektdeltagarna skrev efter av

Multivariable controller design for hot rolling mill

This paper describes a controller design for a hot rolling mill. The main purpose of the algorithm is to improve the control of the cross-width thickness profile of the plates. This is obtained by designing a controller which makes independent thickness control possible at the two sides of the rolling mill. This is obtained by first linearizing the positioning systems using feedback linearization

The Fall of Reichenbach

Reichenbach’s constraint is the methodological imperative formulated by Reichenbach in the following passage: “If we want to construct a philosophy of science, we have to distinguish carefully between two kinds of context in which scientific theories may be considered. The context of discovery is to be separated from the context of justification; the former belongs to the psychology of scient
