background and aims. autogenous bone graft is commonly used for reconstruction of bone defects in routine surgical procedures. the complexity of producing bone grafts and their application has lead to the use of human bone matrix gelatin (hbmg). the present study was conducted to compare the efficacy of hbmg and autograft on the reconstruction of bone defects in rats. materials and methods. in ...

congenital myasthenic syndromes (cms) are a group of diseases caused by genetic defects affecting neuromuscular transmission and are heterogeneous in inheritance and pathophysiology. these are classified as: 1. presynaptic defects: including choline acetyl transferase deficiency, paucity of synaptic vesicles, lambert-eaton like cms 2. synaptic defect: endplate ach esterase deficiency 3. postsyn...

We fabricated indium gallium nitride (InGaN) red light-emitting diodes (LEDs) with a peak emission wavelength of 649 nm and investigated their electroluminescence (EL) properties. An additional separated in the EL spectrum LEDs at 20 mA was observed 465 nm. This also exhibits blue-shift increasing currents as does main peak. Using high-resolution microscopy, we many point-like spots images belo...

Several previous studies have been dedicated to incorporating double defect modes of a phononic crystal (PnC) into piezoelectric energy harvesting (PEH) systems broaden the bandwidth. However, these prior are limited examining an identical configuration defects. Therefore, this paper aims propose new design concept for PnCs that examines differently configured defects broadband elastic wave loc...

We present a new solution for the problem of ultra high energy cosmic ray events with energy up to 3 10 20 eV. Various authors have considered that these events are caused by the decay of supermassive particles emitted by topological defects formed during the symmetry breaking of a GUT. However, in the frame work of supersymmetric theories, the decay of topo-logical defects should produce not o...
