A fragility analysis methodology is developed for assessing the response of light-frame wood construction exposed to stipulated extreme windstorms and earthquakes. Performance goals and limit states (structural and nonstructural) are identified from a review of the performance of residential construction during recent hurricanes and earthquakes in the United States. Advanced numerical modeling ...

Failure in cold-formed steel beams is generally initiated by one of three instabilities: local, distortional, or lateral-torsional buckling. For cold-formed steel joists, purlins, or girts, when the compression flange is not restrained by attachment to sheathing or paneling, distortional buckling may be the predominant failure mode. Experimental results on cold-formed steel beams with unrestrai...

The sheaths that invest the nerves of amphibia, insects and freshwater clams differ in structure. Previous studies have shown, though, that the nerves of all these animals have in common the ability to function for extended periods in sodium-free solutions (Krnjevid, 1954; Twarog & Roeder, 1956; Carlson & Treherne, 1969). In amphibia and insects, it has been shown that this capacity is lost if ...

PURPOSE The purpose of this study is to report a case of Kyrieleis plaques (segmental retinal periarteritis) associated with cytomegalovirus (CMV) retinitis. METHODS A 47-year-old female with recently diagnosed human immunodeficiency virus and a CD4 count of 55 cells/µl presented with decreased vision and floaters in her left eye. Ophthalmic examination revealed an advancing border of white g...

Astrocytes are increasingly believed to play an important role in neurovascular coupling. Recent in vivo studies have shown that intracellular calcium levels in astrocytes correlate with reactivity in adjacent diving arterioles. However, the hemodynamic response to stimulation involves a complex orchestration of vessel dilations and constrictions that spread rapidly over wide distances. In this...

• Pseudo-static cyclic tests on Cross-Lam Timber (CLT) and Light Frame (LTF) shear walls. Decomposition of the post-elastic displacement into sliding, rocking deformation components. Similarity two structural responses due to same resisting mechanism. A capacity model based sole hold-down reaction seizes overall response. The estimated overstrength factors manifests intrinsic differences betwee...

The rapid economic, scientific and technical development of the Republic Kazakhstan in order to achieve modern level technological requires a wide production metal products equipment using technically economically effective methods. For this purpose, one main ways producing corrosion-resistant efficient parts is cadmium plating. Cadmium plating flexible, easily amenable rolling, stamping, bendi...

Purpose: We report a case of bilateral frosted branch angiitis caused by anti-phospholipid antibody syndrome.Case summary: A 60-year-old female complained worsening vitreous floaters and decreased visual acuity in both eyes. The initial best-corrected (BCVA) was 0.8 the right eye 0.05 left. On slit-lamp examination, inflammatory findings were observed anterior chamber body fundus vascular sheat...

The predominance of the primary sector is noticeable in economy most African countries, particularly Benin. Thus, to make this a vector wealth and development, it imperative think about development technologies improve efficiency processing product quality. mechanization therefore necessary more competitive. In Benin we have lot products which are made with coconut. This has been relegated non-...

Purpose: to study the effect of nonlinear soil movement in a deep-laid pit when designing an above-ground reservoir for irrigation as part system regulating precipitation runoff mountain-piedmont zone, subject technical regulations on structure safety and subsequent safe operation. Materials methods: construction difficult geological design conditions zone hydraulic structure, which is responsi...
