Short stemmed hip endoprostheses represent a relevant alternative to standard sized total hip stems. Especially in terms of bone stock preservation and minimal invasiveness the reduced length of such implants is beneficial. However, the smaller implant size is linked to a reduced surface geometry and thereby bone-implant-interface to provide implant stability. In order to evaluate the interfaci...

The increase in the number of shoulder arthroplasties has also created a paradoxical increase in the number of revision procedures. These revision surgeries can be complicated by well-fixed humeral components that require removal. In this article, we report a representative revision arthroplasty that involved a novel technique, vertical humeral osteotomy, which allowed for safe and effective hu...

~ Genetics research in southern hardwoods has moved, during the past decade, from a minor position in a few organizations to major status in most of the South's forest research establishments. This new interest in hardwood tree improvement has stemmed largely from (1) the increasing use of hardwoods for pulp and (2) a decreasing supply of high-quality hardwood sawtimber. These two aspects of th...

The Israeli science education at the junior high school level has undergone a major change during the last several years. This change stemmed from a decision to merge the different scientific disciplines, which were formerly studied independently, together with technology, to form a new curriculum named “Science and technology” (The Israeli ministry of education, 1996). In addition, it was deci...

We propose a technique for effective extraction of bilingual phrases from word alignments using morphological processing. Morphological processing leads to an increase of the frequency of words in the corpus, consequently reduces Alignment Error Rate (AER). Intuitively, better word alignments enhance the quality of bilingual phrases extracted. Using alignments of a stemmed corpus for phrase ext...

The move to relational probabilistic models from propositional models stemmed from the realization that the type of knowledge we have and need in many domains is at a level more generic than that of concrete objects. In reasoning about preference, too, often we have knowledge about the desirable behavior or state of a system of agents/objects, that applies to different instantiations of this sy...

There is little understanding of how anionic surfactants affect the transport carbon dots (CDs) nanoparticles in soil. In this study, mobility characteristics CDs soil columns with sodium dodecyl sulfate (SDS, a model surfactant) under various conditions were investigated. The results showed that presence SDS enhanced at pH 7.0 when Na + was main background electrolyte. increased electrostatic ...
