The Schwarzschild-Villiger effect has been experimentally demonstrated with the optical system used in this laboratory. Using a photographic mosaic specimen as a model, it has been shown that the conclusions of Naora are substantiated and that the SV effect, in large or small magnitude, is always present in optical systems. The theoretical transmission error arising from the presence of the SV ...

 Thin-walled energy absorbers are used to reduce accident induced damages. In this study, thin-walled stainless steel structures in quasi-hemisphere geometry were subjected under quasi-static loading with Santam 150KN apparatus. Experimental results were compared with results of numerical simulations by LS-DYNA and it was shown that there is a good agreement between experimental and numerical r...

Adobe is commonly found in Aveiro's ancient constructions. Preservation and rehabilitation of those constructions, some of them with architectural and historical interest, has been forgotten for many years. As a result, in Aveiro region, the majority of existing constructions in adobe is structurally weak, and, in several cases, they are in the threshold of ruin. Rehabilitation and/or strengthe...

A partial skeleton from the Little Snowy Mountains of central Montana is the first referable specimen of the Morrison Formation macronarian sauropod Camarasaurus. This specimen also represents the northernmost occurrence of a sauropod in the Morrison. Histological study indicates that, although the specimen is relatively small statured, it is skeletally mature; this further emphasizes that size...

A small mill has been developed for reducing nail clippings to a convenient size for microscopy and inoculation onto isolation media. The milling process acts to pulverize and homogenize the specimen. The use of a homogeneous sample in microscopy increases the opportunity for the discovery of fungal hyphae in a specimen. The use of a pulverized specimen increases the possibility of culture isol...

Problem statement: Nowadays, the use of waste tyre in concrete has become technically feasible and the tyre mixed concrete is light weight and called as rubberized concrete. Still the research is going on to explore basic engineering properties such as transport properties viz, acid absorption test, water absorption tests, impact resistance, modulus of elasticity, dynamic modulus and so on. In ...

Scanning electron microscopy (SEM) and Transmission Electron Microscopy (TEM) is a chemical instrument that can be used to evaluate the characteristics of material. Techniques determine morphology diameter size However, until now there has been no publications describes in detail read interpret images both SEM TEM. The purpose this paper demonstrate steps how calculate based on level difficulti...
