Coastal marine ecosystems provide essential benefits and services to humanity, but many are rapidly degrading. Human activities leading significant land take along coastlines major changes in ecosystems. Ecological engineering tools capable of promoting large-scale restoration coastal needed today the face intensifying climatic stress human activities. Concrete is one materials most commonly us...

Food is a complex matrix of proteins, fats, minerals, vitamins, and other components. Various analytical methods are currently used for food testing. However, most the require sample preprocessing expensive chemicals. New needed quick economic measurement quality safety. Fluorescence spectroscopy simple method to measure quality, without preprocessing. This technique has been developed samples ...

Due to rapid urbanization, more than half of the world's population now live in cities. By the year 2050, the urbanized population will increase to two–thirds of the global population, which prompted increased international attention to identifying environmental, social and economic challenges of urban development encompassing diverse aspects such as energy, water, waste, infrastructure, transp...

Frequency lowering in hearing aids is not a new concept, but modern advances in technology have allowed it to be performed more efficiently and on select portions of the spectrum. Nonlinear frequency compression reduces the frequency spacing in a band of high-frequency energy so that more information is carried in the audible bandwidth. Frequency transposition and translation techniques lower o...

the effects of some synthetic sweeteners on the rheological and physical properties of guar gum in dilute solutions were investigated.measurements include the determination of intrinsic viscosity and the particle size, surface weighted mean [d3, 2], volume weighted mean [d4,3] and specificsurface area ofguar gum andsyntheticsweeteners mixtures. the concentration of these sweeteners were 0, 0.1,...

Conservation ethics have been based on 2 philosophical value systems: extrinsic value (defined broadly to include all values that derive from something external to the thing valued) and intrinsic value. Valuing biological diversity on the basis of an extrinsic value system is problematic because measurement is often difficult; extrinsic value changes as spatial or temporal scales change; extrin...
