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...
The objective of this study was to investigate the adhesion of isolated spoilage bacteria to packaging materials used in the food industry. Microorganisms were isolated from commercial fruit-flavored mineral water in plastic bottles with flocks as a visual defect. The Gram-negative rods were identified using the molecular method through the amplification of a partial region of the 16S rRNA gene...
Industry throughout the world is faced with a common problem that of the disposal of waste materials from manufacturing processes. In the case of the dairy industry, one such 'waste' which is produced in enormous quantities is the whey resulting from cheese and casein manufacture. In the 1996/97 season alone it is estimated that around five billion litres of whey were produced in New Zealand. I...
The application of remote sensing sciences in the field geology is very diverse and wide. One its most important applications earth geological mapping. Mineral exploration using techniques done different ways, one them mapping alteration zones related to mineral resources. Given importance geosciences today's industry given that deposit-related areas are exploratory keys. this review study meth...
In Latin America, metallic ores are abundant and diverse. However, few metal-tolerant and metal hyperaccumulator plants have been reported in the region in comparison with other areas of the world. This may be largely explained by the scarcity of scientific studies of the native vegetation growing on natural mineralized or metal-contaminated areas and the unfrequent use of biogeochemical prospe...
This article examines the importance of path dependence effects in impeding the diffusion of high throughput mechanized mining systems in the British coal industry. It demonstrates that the industry had become ‘locked in’ to low throughput underground haulage technology, on account of institutional interrelatedness between Britain’s traditional practice of extensive in-seam mining and its uniqu...
The oil and gas industry is highly risky capital-intensive field of business. Many companies are working hard to perform projects on a global scale in order to get, produce and deliver their final products. No matter the economic conditions, it is vital for organizations to efficiently manage their capitals projects, which facilitates to control expenditure, handle priorities and mineral resour...
During the 2000 field season, both regional and detailed till sampling surveys were conducted in the Cariboo region of central British Columbia (Figure 1). These surveys complement the longer term objectives of the NATMAP Ancient Pacific Margin (APM) project (see Nelson, 2000) and provide continuity to the surficial till geochemistry work initiated by Dixon-Warren and Hickin (2000) in 1999 as p...
Cameroon has a strong geological potential for a number of mineral resources that, if well managed, could support economic growth. The country contains potentially large deposits of iron ore, gold, bauxite, diamond, limestone, nickel, and gemstones, and indices of other numerous minerals and precious metals. Despite its geological wealth, mining has never played a major role in Cameroon’s econo...
