For Newtonian fluids, the apparent (or uncorrected) shear rate at the wall of a die (˙γw,a) is equal to the true shear rate (˙γw) However, with non-Newtonian fluids, such as polymer melts, the two are not equal but are related by the equation: γw = [(3n1 +1)/4n1] ˙...
Making arrays of precise 3D micro- and nanoresonators is still a challenging problem. Here we present a versatile set of approaches to fabrication of metamaterials with 3D resonators rolled-up from strained films, demonstrate novel THz metamaterials/systems, and show giant polarization rotation by ...
15 feet long and 9 feet wide” (Hogarth1974) and a single euhedral crystal from the Aetna mine measuring 2.1 × 1.2 m with an estimated weight of 6 tons (van Velthuizen1992) were found. None of them is a pure compound; they always contain dopants of other elements. For example, ions...
The potential adverse health effects of exposure to informal e-waste disposal and recycling have been reported to include elevated levels of contaminants in blood, milk, and other bodily fluids, genotoxicity, endocrine disruption, immunotoxicity, nephrotoxicity, abnormal reproductive development, intellectual...
Bimetallic thermometers C, P Used for real-time temperature measurement in fluids. Fibre-optic temperature sensors C, P Integrated-circuit (IC) temperature sensors C, P Irreversible/change-of-state temperature sensors B, P(CL) Soap (which changes state at a single temperature) is often used...
Learn how to stop losing VITAL sexual fluids and transmute it using at least seven controversial tools of transmutation to help master your relationship with vital, subtle energy. Learn how to use that energy, correct eating, plenty of mineral water and herbs to blissfully transmute the sexual ...

A sustainable use of natural resources is pursued by developing new materials using waste as raw material, reusing them or recycling them in part or in its whole. Eco-materials with absorbent acoustic properties—like recycled plastic bottles (PET), natural fibers such as kenaf [3], coconut [...
Any type of liquid or gaseous fluid may be used. Liquid fluids may include water or organic solvents such as ethanol or methanol. Suitable gases such as nitrogen, air or carbon dioxide may be used, as well as mixtures of liquids and gases. Any such fluid is preferably non-swelling (i.e...
One characteristic of titanium is that it is biocompatible with human tissue fluids and inert to the corrosive actions that they cause. It is also recognized, that an implant fabricated of titanium is able to provide the necessary level metallurgical strength in reaction to stress and load ...
