Neurofibromas are benign peripheral nerve sheath tumors seen arising both sporadically and in patients with neurofibromatosis syndromes. Commonly they of three types: localized, diffuse or plexiform. Pigmented neurofibromas very rare, accounting to <1% all reported. We present a case 64 year old woman Neurofibromatosis 1, large swelling on the right thigh. The mass was grossly pigmented micr...

Self-propagating exothermic formation reactions have been intensively studied in a variety of reactive multilayer foils, such as Ni/Al, Ni/Si, and Nb/Si foils. These foils contain numerous alternating nanoscale layers of elements with large negative heats of mixing. With a small thermal pulse, atoms diffuse normal to the layering and result in a rapid exothermic reaction. The heat produced is c...

We have produced thick-foil and fine-pitch gas electron multipliers (GEMs) using a laser etching technique. To improve production yield we have employed a new material, Liquid Crystal Polymer, instead of polyimide as an insulator layer. The effective gain of the thick-foil GEM with a hole pitch of 140 μm, a hole diameter of 70 μm, and a thickness of 100 μm reached a value of 10 at an applied vo...

Pigmented Bowens disease is an in situ squamous cell carcinoma, which is seldom reported in white patients. Herein we report a 20-year-old woman with type III skin, who had this lesion on the fourth finger of her right hand, similar to superficial malignant melanoma, clinically. Although dermoscopic evaluation could be helpful, correct diagnosis of non-melanotic origin is done by histological e...

In the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. Initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. Then the pigmented samples were scanned, and the values of RGB of images were calculated. The artificial neural network (ANN) method used to make relation between RGB va...

In many natural communities communication between plants and other organisms below ground drives community dynamics. This communication is primarily through the release and detection of infochemicals, which must traverse the soil matrix to be effective. In this opinion article, we propose the Network Enhanced Bioactive Zone (NEBaZ) model, which posits that common mycorrhizal networks (CMNs) inc...

OBJECTIVE To present our experience of reconstruction of the nasal septum using perforated and unperforated foils, particularly with respect to functional and aesthetic sequelae. METHODS A retrospective medical record review of a prospectively conducted case series was undertaken of all consecutive patients who underwent septal reconstruction using polydioxanone foil in a 4-year period. Proce...

Magnetic Fano resonances in there-dimensional symmetry broken meta-foils at THz frequencies are theoretically and experimentally studied. Sharp Fano resonances occur due to the interference between different resonances and can be designed by choosing geometric parameters of the meta-foil. At the Fano resonances, the meta-foil supports antisymmetric modes, whereas, at the main resonance, only a ...

This paper describes an experiment performed to verify the one-dimensional model of elastic foil behavior developed by Stahl, White, and Deckert [ 11. In the experiment, a loop of tape one-inch wide passes over a stationary recording head, and the air-film thickness between the head and the foil is determined using white light interferometry. Measured data for various experimental conditions ar...
