In effect, hydrogen and oxygen are different substances, or to be more specific, they are different elements. There are quite a number of elements known in the current time. Thanks to the works of our early scientists, they were able to systematically organize all of these elements in what we call the periodic table of elements or sometimes ...

Dyes are a significant group of organic contaminants known to negatively affect both humans and aquatic environments. In the textile industry, interest in agricultural-based adsorbents has increased, particularly around adsorption. In this study, methylene blue was eliminated from an aqueous solution using a walnut (Juglans regia) shell. …

The emergence of digital electronics has had a tremendous impact on industrial societies throughout the world. In the heating, ventilating, and air-conditioning (HVAC) industry, the development of digital electronics has brought an end to the use of many mechanical devices; typical of this is the diminished use of mechanical controls for HVAC air and …

Kronan, also called Stora Kronan, was a Swedish warship that served as the flagship of the Swedish Navy in the Baltic Sea in the 1670s. When built, she was one of the largest seagoing vessels in the world. The construction of Kronan lasted from 1668 to 1672 and was delayed by difficulties with financing and conflicts between the shipwright Francis …

There is a great potential for MICP to be applied in the reusing and recycling of calcium-based solid waste from the abundant sources (Seifan and Berenjian, 2019; Chuo et al., 2020).It is noteworthy that solid wastes generated from mining, iron and steel metallurgy, power generation, and manufacturing industries, such as burnt ashes, slag, …

ABSTRACT Utah offers spectacular geologic features and valuable analog environments and processes for Mars studies. Horizontal strata of the Colorado Plateau are analogous to Mars because the overprint of plate tectonics is minimal, yet the effects of strong ground motion from earthquakes or impacts are preserved in the sedimentary record.

Pollution and the global health impacts from toxic environmental pollutants are presently of great concern. At present, more than 100 million people are at risk from exposure to a plethora of toxic organic and inorganic pollutants.
