the one-dimensional model of lippincott and schroeder for hydrogen bond has been re-examined and it has been shown that o-h bond distance depends on repulsive van der waals and attractive electrostatic potentials.it has been shown that constant b in the van der waals repulsion potential is not transferable to all hydrogen bonds. the possibility of obtaining the semi-empircal parameters in the l...

Hypericin is a potent agent in the photodynamic therapy of cancers and accumulates to a large extent in tumor tissue. To better understand the impact of hypericin aggregates present in the delivery vehicle on the biodistribution of the compound, we compared the in vivo tissue accumulation after administering hypericin suspended as coarse aggregates in phosphate-buffered saline, with the biodist...

Software contains bugs and bugs cost money. A good way to find some bugs quickly is the use of static code analysis. There are no exact numbers on the use of static code analyzers in the industry, but in our experience to few software developers actually make use of them. This thesis describes a survey that was conducted to find out why only so few developers in the Java community use static co...

Bei Springer blicken wir inzwischen auf eine dreijährige Open-Access Erfahrung zurück. In meinem Beitrag werde ich das spezifische Springer-Modell unter dem Namen Open Choice kurz darstellen und erläutern, wie es im wissenschaftlichen Umfeld angenommen und genutzt wird. Ich werde auch am konkreten Beispiel der Max-Planck-Gesellschaft umreißen, wie wir in einem Pilotprojekt Zeitschriftenabonneme...

Given my current state of knowledge, and a desirable state of knowledge, how do I get from one to the other? It is possible in principle to reach the desirable state of knowledge, i.e., does it make sense at all to start trying to obtain the desirable state? If I know it is impossible to obtain, there is no use trying. But even if I know that it is possible in principle, is there a way to appro...

They describe a unique case of the two syndromes occurring concurrently though apparently independently in a girl with Van der Woude syndrome and pituitary insufficiency associated with clefts before correctly diagnosing Turner syndrome [2]. Typical blind fistulas of the lower lip,...

Whether Van Gogh (1853–1890) had epilepsy has been subject to doubt and conjecture in the fields of art and medicine. Even epileptologists have had divergent views. Gastaut admitted that Van Gogh had epilepsy, but considered that his seizures were triggered by alcohol [1–3], whereas according to Hughes, Van Gogh more likely suffered from fainting fits [4]. The recent edition of Van Gogh's corre...

417 Human auditory localization is remarkably accurate, even in complete darkness under open-loop conditions1–4 (Fig. 2; see also Methods). This performance may rival that of the barn owl, a well studied nocturnal hunter that relies heavily on its auditory system to capture prey. Yet, quite different localization mechanisms are used by each species. In barn owls, sound azimuth (horizontal direc...

A sequence of throws of a die will look very irregular and chaotic to us; even if we already observed the outcomes of a thousand throws, we are not in a position to predict the outcome of the next throw. We might call this phenomenon local irregularity, or disorder. However, even though we cannot predict the outcome of the next throw, we feel confident that in the long run, the relative frequen...
