Pete Maravich's incredible heart

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.     

Rules,Institutions, Transformations. Considerations on the “Evolution of Law” Paradigm

The article's main objective is to test the merits of the evolutionary paradigm as it has been applied first to social phenomena and then more specifically to the legal domain. In a preliminary move, a set of the available concepts of law is worked out. A discussion of the idea of evolution and of its use in the social sciences follows. Functionalism and systems theory are scrutinized, with a close eye to the new doctrine of “autopoiesis.” Once an institutional and normative concept of law is agreed upon, attempts to introduce an “evolutionary” paradigm are deemed—the article contends—to be unfruitful. The article concludes that, if law needs a metaphysics, it should be one which allows for change, transformation and the emergence of the radically new. A social universe without gaps, all possible forms of which are determined from the beginning, will end up as the opposite of what we are used to considering as the practice of law.

Sensitivity of various study technics in blood stains

Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood.
