In this paper, considering symmetric collapse mode for hybrid tubes, and using Tsai-Hill fracture criterion to take into account the off-axis strength of an orthotropic lamina, an analytical model is extended and an expression is derived for mean crushing load and fold lengths of circular hybrid tubes. In this model, the influences of the geometrical dimensions including diameter, thickness of ...

Peripheral nerve injury induces inflammation and oxidative stress, which are the most significant causes of the neuronal death. Alpha Lipoic acid (ɑ-LA) as a potent antioxidant and anti-inflammatory agent may counteract the oxidative stress and inflammatory response. This study was designed to investigate the protective effect of ɑ-LA on neuronal cell death in L4 dorsal root ganglion (L4-DRG) i...

Lipedematous scalp (LS) and Lipedematous Alopecia (LA) are uncommon disorders of unknown etiology, pathogenesis and treatment. They are characterized by thickening of the subcutaneous layer of the scalp and a boggy scalp on palpation. Also, hair loss or shortening of hair is seen in LA. In this report, we describe LS in a 42-year-old woman presented with a diffuse thickened and spongy scalp. To...

The Fibonacci lengths of the finite p-groups have been studied by R. Dikici and co-authors since 1992. All of the considered groups are of exponent p, and the lengths depend on the celebrated Wall number k(p). The study of p-groups of nilpotency class 3 and exponent p has been done in 2004 by R. Dikici as well. In this paper we study all of the p-groups of nilpotency class 3 and exponent p2. Th...

this research explains the morphometric characteristics of varroa destructor anderson and trueman in tehran province. 180 adult female mites were collected from three different colonies of apis mellifera l. in three apiaries during september 2003 to may 2004. these colonies were divided according to three altitudes-less than 1000m, 1000-1500m and more than 1500m above the sea level. the morphol...
