a 15- year-old boy with history of bb gun injury to his left eye was referred to our center. his visual acuity was no light perception in the left eye. ocular findings were severe proptosis, conjunctival injection, and conjunctival vascular tortuosity. fundus examination revealed an extensive inferior chorioretinal scar compatible with chorioretinitis sclopetaria. a distinct bruit was detected ...

—We captured 1,055 Nelson’s (Ammodramus nelsoni) and Saltmarsh (Ammodramus caudacutus) sparrows during the winter season (2006–2014) within the outer Coastal Plain of Virginia to determine the composition of subspecies. Birds were captured using mist nets in 24 tidal salt marshes and identified to subspecies using a plumage-based, syntopic key. Contrary to previous assessments, both species of ...

Sparrows in the nine-primaried oscine family Passerellidae represent an attractive model for studying avian diversification across North and South America. However, the lack of phylogenetic resolution at the base of the New World sparrow tree has hampered the use of the existing sparrow phylogeny to test questions about the evolution of sparrow traits. We generated phylogenomic data from 1,063 ...

The renal anatomy of three species of sparrows, two from mesic areas, the House Sparrow (Passer domesticus) and Song Sparrow (Melospiza melodia), and one salt marsh species, the Savannah Sparrow (Passerculus sandwichensis) was examined. Electron microscopy was used to describe the ultrastructure of the nephron. In addition, stereology was used to quantify the volumes of cortex, medulla, and maj...

Abstract The interior ballistic potential equilibrium theory is used to analyse the parameters at points of pressure curves 30mm conventional launching experiment and electrothermal-chemical (ETC) experiments. Analysis shows that: compared experiment, (1) time for ETC arrive point apparently shortened; (2) relative burnt percentages propellants are smaller in tests. And gas generation brisance ...

A new paradigm for an effective delivery of therapeutics into cancer cells is presented. Degradable porous silicon carriers, which are tailored to carry and release a model anti-cancer drug, are biolistically bombarded into in-vitro cancerous targets. We demonstrate the ability to launch these highly porous microparticles by a pneumatic capillary gene gun, which is conventionally used to delive...

Impressive gains have been made in thermal spray coatings through material development and coating parameter selection. Nevertheless, it is usually up to shop personnel to develop a robot program to achieve the final coating. Coating programs are often developed using trial and error. Some motion and deposit analysis programs are available [1], [2]. However, they can be costly and require a lev...
