Pyramid has been variously studied for its mystical preservative, healing and curative effects. The power of the pyramids has been much talked about in Egypt and the great pyramids as the wonders of the world. They are mentioned as çikhariëis and gopurams used in temples in Indian tradition. It is associated with Chakras and the elevation of the human mind to the super-consciousness levels. Alt...

We report the synthesis and fatigue characterization of fiberglass/epoxy composites with various weight fractions of graphene platelets infiltrated into the epoxy resin as well as directly spray-coated on to the glass microfibers. Remarkably only ∼0.2% (with respect to the epoxy resin weight and ∼0.02% with respect to the entire laminate weight) of graphene additives enhanced the fatigue life o...

Finite element analysis (FEA) was used to investigate the influence of different post systems on the stress distribution of weakened teeth under oblique-load application. A maxillary central incisor root obtained from a sound tooth was weakened by partial removal of dentin inside the root canal. Seven two-dimensional numerical models, one from the sound tooth and six from the weakened root rest...

Methods: The Optic Nerve (ON) coil was constructed using two fiberglass formers that fit together to surround the entire head. The anterior former supports 26 overlapping coil elements in a mask arrangement as shown in Fig. 1. The posterior former supports the neck and head and houses two additional overlapped coil elements, totaling to 28 elements. In this design, the two formers can slide ove...

In the presence of many waves, giant events can occur with a probability higher than expected for random dynamics. By studying linear light propagation in a glass fiber, we show that optical rogue waves originate from two key ingredients: granularity, or a minimal size of the light speckles at the fiber exit, and inhomogeneity, that is, speckles clustering into separate domains with different a...

We report the fabrication of new dehydrated halo-tellurite glass fibers with low OH content (1ppm in weight) and low OH-induced attenuation of 10dB/m in 3-4 µm region. It shows halo-tellurite glass fibers a promising candidate for nonlinear applications in 2-5µm region.

Expansion of black-tailed prairie dog (Cynomys ludovicianus) colonies on public and private lands can result in damage to property. Physical barriers to prairie dogs can be used to minimize human–wildlife conflicts. We evaluated 17 existing barriers in the Fort Collins and Boulder, Colorado, areas. Most barriers were made of a single row of vinyl material; these barriers sustained high levels o...

It is known that aerogel impregnated fibrous blankets offer high acoustic absorption and thermal insulation performance. These materials are becoming very popular in various industrial building applications. Although the reasons for performance of these well understood, it still largely unclear what controls their Additionally, only a small number publications to date report on acoustical prope...

The aim of this study was to compare the effect posts systems and luting agent on bond strength. Thirty single-rooted bovine teeth were used. specimens randomly grouped into: Rely X Ultimate- shaped pin (ULT-M), ULT- accessory (ULT-A), Splendor SAP (ULT-S), U200 (U200-M), U200-A U200-S. sectioned (cervical, middle apical thirds) submitted push-out test using universal testing machine EMIC DL200...
