    Notes: Zusammenfassung Die wachsende Verbreitung eisenloser Induktionsöfen erfordert eine theoretische Untersuchung. Es werden vereinfachte Rechenmethoden angegeben und es wird gezeigt, daß unter bestimmten Bedingungen ein zufriedenstellender Betrieb bei normalen Starkstromfrequenzen erzielt werden kann. Ein Ofen für 45 kg Messing und 50 Perioden wurde gebaut, um die Brauchbarkeit der Theorie zu erweisen. Wassergekühlte Spulen für so niedrige Frequenzen bereiten gewisse Schwierigkeiten. Es wird eine besondere Konstruktion beschrieben, die sich bewährt hat. Versuche an dem 45 kg Ofen werden mitgeteilt und ergeben gute Übereinstimmung mit der Theorie. Aus der Untersuchung wird gefolgert, daß ein Ofen für 300 kg Messing bei 50 Perioden gute Betriebseigenschaften zeigen würde.

    Notes: [Auszug] THE accompanying photographs (Fig. 1) represent a somewhat extraordinary manifestation—a single electrode arc. The discharge is produced by the application of alternating voltage of the order of 5 kv. at frequencies higher than about 10,000,000 cycles to an electrode consisting of a short ...

Wound Healing Properties of Reconstituted Freeze-Dried Platelets (2005)

    Notes: The use of fresh platelets has gained value in medicine as an essential part of wound treatments. This is not surprising since platelets contain a number of bioactive factors that contribute to the process of wound healing, such as platelet-derived growth factor (PDGF) and transforming growth factor (TGF). Fresh platelets’ short shelf life limits platelet-based therapies. If platelets can be stabilized in freeze-dried form (FDP) then long-term storage as well as pathogen inactivation methods become possible. Adlyfe and Oregon Freeze-Dry have been developing technology to stabilize freeze-dried human platelets that can be subjected to gamma irradiation and stored for a long duration. Upon reconstitution, irradiated FDP retained growth factors PDGF-AB, PDGF-BB, and TGF-B1 in quantities similar to fresh platelets as judged by capture ELISA. The rehydrated FDP promoted new DNA synthesis and cellular proliferation of primary human dermal fibroblasts and endothelial cells (HUVECs) similar to fresh platelets. The FDP also promoted remodeling of extracellular matrix by accelerating fibroblast-mediated contraction of collagen gels and stimulated HUVECs to undergo angiogenesis and form capillary structures in vitro. Therefore, we conclude that FDP and fresh platelets have comparable in vitro wound healing potential. Preclinical wound healing stud"ies in diabetic mice are under way and further development will allow FDP to be a safe and well-suited alternative to fresh platelets for wound healing applications.

    Notes: Abstract Broken straight lines on probability paper have been proposed as representing the cumulative probability distributions of SiO2, Na, and Cl in certain plutons. This corresponds to pairs of complementarily truncated normal or lognormal distributions. It is shown that alternative representations, such as pairs of overlapping complete normal or lognormal distributions, yield fits equally acceptable statistically if the sample selection is random. The method also yields a good description of distributions described as “complex.” Computer methods of optimizing the free parameters are used; significance testing is discussed in some detail. It is stressed that although significance testing is helpful, it can neither relieve the geochemist of the burden nor take from him the privilege of being independent, and forming his opinion on the total evidence.
