pineal bodies usually contain a concretion called brain sand. concretion is mostly composed of phosphate and calcium carbonate. the concretion increases with age, however the origin and mechanism of formation of these materials are not clearly understood. calcified bodies are usually used as a guide in radiographic studies. due to the importance of these materials, this research was done on bra...

Introduction Each June, Wimbledon Centre Court becomes the focal point for the performances of the world’s leading tennis players. Matches showcase pure theatre—the drama, the sweat, the joy and tears, not to mention the physique of the players and the contortions of their bodies as they move around the court. In 2011, Bethanie Mattek-Sands arrived on court at Wimbledon in a costume designed by...

M. Łucarz, AGH University of Science of Technology, Engineering of Faculty Foundry, Kraków, Poland The paper presents the results of the research on the used moulding sands subjected to mechanical and thermal reclamation at different stages of the process in the foundry. The research on thermal treatment was carried out in an experimental thermal reclamation appliance. The effects of the proces...

Yes, to dance beneath the diamond sky with one hand waving free Silhouetted by the sea, circled by the circus sands-Bob Dylan

Enterococci are used to assess the risk of negative human health impacts from recreational waters. Studies have shown sustained populations of enterococci within sediments of beaches but comprehensive surveys of multiple tidal zones on beaches in a regional area and their relationship to beach management decisions are limited. We sampled three tidal zones on eight South Florida beaches in Miami...

Dispersed clay particles in mine tailings and soft sediments remain suspended for decades, hindering consolidation and challenging effective management of these aqueous slurries. Current geotechnical engineering models of self-weight consolidation of tailings do not consider microbial contribution to sediment behavior, however, here we show that microorganisms indigenous to oil sands tailings c...

Microorganisms associated with coastal sands serve as a natural biofilter, providing essential nutrient recycling in nearshore environments and acting to maintain coastal ecosystem health. Anthropogenic stressors often impact these ecosystems, but little is known about whether these disturbances can be identified through microbial community change. The blowout of the Macondo Prospect reservoir ...

Optimal hydrocarbon recovery depends strongly on predicting the reservoir quality and drive mechanism, this could be achieved by petrophysical analysis. This research evaluated properties of sands in an Oil producing Field, onshore Niger delta, Nigeria using techniques. Results from Petrophysical evaluation, showed that average porosity values reservoirs ranged between 0.15 0.24 while water sat...
