Around 6-20% of monostotic FD occurs in the ribs. The objective of this study was to report our experience in the management of the monostotic FD of the ribs. Between January 2004 and December 2009, seven cases of FD of the rib (six men and one woman, mean age 30.4 years, range 17-40 years) were operated on. The patients were evaluated with plain radiographs and computer tomography (CT). All our patients were symptomatic; two patients presented chest pain and swelling and other patients presented only chest pain. One rib was involved in all our

patients (monostotic form): the site was fifth rib (four cases), sixth rib (two cases) or second rib (one case). Radio logically, plain Selleckchem Autophagy inhibitor films and selleck kinase inhibitor CT showed an expansible lesion with a ground-glass centre and thinning of the cortex. Rib resection was performed in all patients; there were no postoperative complications and no recurrence in all cases at mean 43 month follow-up. In symptomatic monostotic FD of ribs, the involved segment of bone

may be excised to rule out malignancy and for painful lesions.”
“Fiber separation from corn flour could increase ethanol productivity and increase energy value as feed for non-ruminants (swine and poultry). Elusieve process, a combination of sieving and air classification, has been found to be effective in separating fiber. The objectives of this study were to determine the operating air velocities for corn particles and to compare physical properties of corn particles with that of DDGS particles from an earlier study. The operating air velocities for large,

medium and small corn size fractions were 2.9-3.8,2.8-3.0 and 2.5-2.6 m/s, respectively. Densities of nonfiber particles for corn flour were higher selleck chemicals llc than for DDGS (earlier study). Compared to DDGS, the difference between fiber and nonfiber particle terminal velocities was higher for corn, which signifies relative ease of operability for fiber separation from corn flour.

“Biogenic volatile organic compounds (BVOCs), released by practically all plants, have important atmospheric and ecological consequences. Because BVOC-emission measurements are especially tedious, complex and extremely variable between species, two approaches have been used in scientific studies to try to estimate BVOC-emission types and rates from plant species. The first, which has known little success, involves grouping species according to plant-taxonomy criteria (typically, genus and family). The second involves studying the correlation between BVOC content and emission (i.e. how leaf content could be used to estimate emissions). The latter strategy has provided controversial results, partly because BVOCs are amazingly chemically diverse, and, as a result, techniques used to study plant BVOC content, which we review, cannot be equally adequate for all analytes.
