Mechanical properties of particulate goat bone reinforced epoxy composite were investigated in this research. This was aimed at assessing the suitability of the developed composites for biomedical applications. The combination of the two materials for the development of the composites was targeted to meet good surface compatibility in addition to the structural compatibility needed as biomateri...

It has been 20 years since the last estimate of the public health workforce's size and composition. This study provides a best estimate through secondary analysis of existing workforce reports, summaries, and information gathered from chief health officials in 50 states and 6 territories, public health organizations, and federal agencies. Results indicate that the workforce consists of some 448...

We investigate the structure of the Minkowski sum of standard simplices in R. In particular, we investigate the one-dimensional structure, the vertices, their degrees and the edges in the Minkowski sum polytope. 2000 MSC: 52B05, 52B11, 05C07.

Let A be a finite nonempty set of integers. An asymptotic estimate of several dilates sum size was obtained by Bukh. The unique known exact bound concerns the sum |A + k ·A|, where k is a prime and |A| is large. In its full generality, this bound is due to Cilleruelo, Serra and the first author. Let k be an odd prime and assume that |A| > 8kk. A corollary to our main result states that |2 · A +...

who were given an antibiotic specifically to treat otitis media, a commonly diagnosed ear condition, declined from 14.4 percent in 1996 to 11.5 percent in 2001, according to new data from the Agency for Healthcare Research and Quality. The data also show declines in both the percentage of children reported to have otitis media and the percentage of children whose parents sought treatment for th...

This study was performed among coal miners in the remote location Svea, Spitsbergen. The shift schedule used to be 7 d on and 7 d off. The aim of this study was to investigate possible changes in health after a voluntary implementation of a new shift schedule, with periods of 14 d on and 14 d off, for 74 percent of the workers in 2007. A questionnaire was distributed to all employees before and...
