Gypsum is a kind of important nonmetallic mineral resources which is widely used in various sectors of the national economy, especially as the main and new raw material for building. The quantity of natural gypsum in Tai’an is very rich, and most of them are large deposit of recoverable ones with about 36 billion tons in total. The rich natural resources of Tai'an will undoubtedly play a decisi...

Agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian  peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. Due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. Currently, environmental laws and regulations pertaining to ...

Spring mineral water might have the properties favourable to health, which should be assessed by clinical and pharmacological analyses. Efforts have recently been made to approach the study of the validity of spring mineral water curative therapies by advanced biochemical research on both animal models and humans. Owing to the paramount interest and the growing recent use of drinking mineral wa...

Atmospheric water vapour interacting with hydrophilic mineral surfaces can produce water films of various thicknesses and structures. In this work we show that mineral particle size controls water loadings achieved by water vapour deposition on 21 contrasting mineral samples exposed to atmospheres of up to ~16 Torr water (70% relative humidity at 25 °C). Submicrometer-sized particles hosted up ...

Nigeria is richly endowed in convertible natural resources of which solid minerals are a member of the endowments. However, the country is basically a mono-product economy based on its vast oil deposit accounting for over 84% of foreign earnings and 25% of GDP. The triple challenges of the volatile nature of global oil politics, achieving the objectives of the millennium development goals and t...

We evaluated the microbiological safety of bottled mineral water products commercially available in Japan. Of 10 bottled mineral water products manufactured in Japan, no bacteria or fungi were detected in 9 (90%), but 1 (10%) contained 1.8x10(3) colony-forming units (cfu)/mL. Of 12 bottled mineral water products manufactured in the EU, 11 (91.7%) contained 23-3.5x10(4) cfu/mL. On the other hand...

In oil industry, recovery of crude oil can be improved by injecting aqueous solutions containing surfactants, polymers, and mineral ions into an oil reservoir. This process is called enhanced oil recovery. Water and oil are immiscible, separated by an interface, and their motion through a capillary tube is governed by the surface tension. However, the physics can be more complex during an enhan...

Mineral elements are essential nutrients for humans and play important roles in many human physiological and bio-chemical processes. In this study, a comparison between the levels of mineral elements present in the water of public drinking fountains (PDRF) and in bottled water was carried out. The aim of the study is to assess the effectiveness of PDRF as a mineral supplement, compared to the l...
