BACKGROUND Frosted branch angiitis is a rare, severe condition. It can be either a primary or a secondary condition and is characterized by rapid deterioration of vision and fulminant retinal vasculitis that manifests as diffuse sheathing of retinal vessels, macular edema, papillitis, vitritis and anterior uveitis. We aimed to describe a case of frosted branch angiitis and cerebral venous sinus...

This study investigated the effect of exposure to elevated temperature on the yield strength of single-shear nail connections when subjected to lateral loading. Solid sawn lumber and laminated veneer lumber were used as framing members and two different thicknesses of both oriented strand board and plywood were used as the sheathing members. The connection geometries evaluated were typical of t...

The ASTM D 1037 six-cycle accelerated-aging test for wood-based panel products was analyzed to determine how each successive aging cycle and selected steps in each cycle contribute to panel deterioration. Hardboard, particleboard, flakeboard, waferboard, and oriented strandboard were evaluated. The rate of panel deterioration generally decreased with each successive aging cycle. Four cycles of ...

This article is devoted to the assessment of efficiency using wall sandwich panels with mineral wool core, sheathing made galvanized steel a polymer coating, used as blast-relief panels. The presents developed seating unit for panel at moment explosion energy influence. As result experiments carried out, when an excess pressure no more than 3.0 kPa in room reached, safety shut-off devices ensur...
