background: : permanent slide preparation of nematodes especially small ones is time consuming, difficult and they become scarious margins. regarding this prob­lem, a modified double glass mounting method was developed and com­pared with classic method. methods: a total of 209 nematode samples from human and animal origin were fixed and stained with formaldehyde alcohol azocarmine lactophenol (...

This paper demonstrates, for the first time, an integrated radio frequency (RF) front-end module (FEM) with precision matching circuits in ultra-miniaturized glass substrates for LTE applications. Through full-wave electromagnetic (EM) simulations, electrical performance of these glass-based long term evolution (LTE) packages is compared with traditional RF modules with surface mount devices (S...

One of the most important methods of saving energy and providing indoor comfort conditions of buildings is the careful design of the façades. A “double skin glass façade” is optimally one of the best options that control the heat interaction between indoor and outdoor spaces. Two kinds of heating energy is usually transmitted through exterior envelope “conduction” and “radiation”. Double skin g...

To understand the spatiotemporal changes in cellular status that occur during embryonic development, it is desirable to detect simultaneously the expression of genes, proteins, and epigenetic modifications in individual embryonic cells. A technique termed methylation-specific fluorescence in situ hybridization (MeFISH) was developed recently that can visualize the methylation status of specific...

The phenomena of white deposits on glass which is in direct contact with or a short distance from an historic, mainly textile, object has been described in literature since the 1970s. The introduction of this article is a short summary of the history of the linen bands of the Liber Linteus. A literature overview throws light on research done in the field of deposits on glass, concerning the obs...

On the turn of the twentieth century the refractor was rapidly approaching its limits in terms of aperture. The main reason for this was the difficulty in manufacturing discs of crown and flint glass with diameters greater than 100 cm. Manufactures of plate-glass could however cast large disks of ordinary crown glass, of lower optical quality, that were suitable for mirrors. It was also known t...

Computer Controlled Ultra-precision Polishing (CCUP) provides an enabling technology for machining freeform components with optical surface quality (i.e., nanometer surface roughness and sub-micrometer or accuracy). It can be used to machine difficult-to-machine materials such as optical glass which are not amenable for diamond machining. Due to the complexity of material removal mechanism in t...
