"Ockham's razor" is a methodical principle, due to the medieval philosopher William of Ockham, who mainly opposed an unjustified creation of new terms in philosophy. Since this principle and its later versions are frequently quoted in discussions about anomalies, it will be studied here in some detail. After a short look on the historical roots, the principal modern formulations are summarized....

TnphoA construct was derived from the transposon Tn5, which contained a kanamycin resistance gene flanked by two IS50 elements. This construct contains a version of the alkaline phosphatase gene with its signal sequence and promoter deleted, which will result in a blue colony phenotype on X-phos (5-bromo-4-chloro-3-indolyl phosphate toluidine salt) containing media when secreted into the peripl...

Entrez 1 is a data retrieval system developed by the National Center for Biotechnology Information (NCBI) that provides integrated access to a wide range of data domains, including literature, nucleotide and protein sequences, complete genomes, three-dimensional structures, and more. Entrez includes powerful search features that retrieve not only the exact search results but also related record...

In all phases of life, from conception to death, the human organism is using its body, in the same sense that F.M. Alexander considered the use in the post-natal period. When the human embryo is about eight weeks old, it has all its major organs and it is moving slowly inside the amniotic fluid. During these early weeks, it is remarkable how the embryo is using its self at each stage to create ...

Objectives: To evaluate the effects of ozone in periodontal treatment in dental practice. Methods: An evaluation of the current state of knowledge regarding the application of ozone in periodontal treatment revealed limited available literature. Therefore an audit was conducted in dental practice in order to evaluate the effects of ozone in periodontal treatment. Twentyfive patients were treate...

In nuclear medicine, analysis, interpretation and diagnosis may each be appropriate as applications for ANNs. Image processing and pattern recognition are two application areas of ANN technology that appear promising. An ANN (21) was used to classify normal and abnormal FDG-PET scans and performed better than discriminant analysis. Favorable results have been obtained from an ANN (22) in the in...

This paper will look at the industrial uses for oxygen. It will categorize oxygen using processes into: 1) the purpose of oxygen in the process and 2) the effect oxygen enrichment has on the overall process. The paper will also look at four methods of producing oxygen: cryogenics, pressure swing absorption, membrane filter technology and electrolysis. It will compare each against one another in...

It is somewhat surprising that many surveys of the field of morphology — even quite comprehensive ones, like Spencer & Zwicky — devote scant attention to the nature of the morpheme, its ontological and epistemological status. ey assume with remarkably little discussion that we know what morphemes are, and where and how to find them, and that the core problems of the field lie elsewhere. My ...
