15 Biodiversity conservation is now about prioritisation, especially in a world with limited 16 resources and so many habitats and species in need of protection. However, we cannot 17 prioritise effectively if historical and current information on a particular habitat or species 18 remains scattered. Several good platforms have been created to help users to find, use and 19 create biodiversity ...

Site geology: The geology of the Oak Park site is one of limestone-drift materials overlying regional limestone-bedrock (over which two broad groups of soils occur: light-textured gravelly soils derived from limestone, and more heavy-textured soils derived from till). The soil underlying Miscanthus-plantations used in the experiments the former type, with a perched clay/subsoil layer under the ...

a long-term study was conducted between 1985 and 2003 on rehabilitation trials at sishen ironore mine, south africa, to identify grass species that would survive in the artificial growth medium appliedto the sites, and to determine the most suitable medium for sustainable vegetation growth. vegetationestablishment was tested at slopes of 18° and 34° and with five different cover materials. afte...

X-ray mammography is widely used for detection of breast cancer. Besides its popularity, this method did not have the potential of discriminating a tumor covered with limestone from a pure limestone mass. This might cause misdetection of some tumors covered with limestone or unnecessary surgery for a pure limestone mass. In this study, Ultra-Wide Band (UWB) signals are used for the imaging. A f...

The paper deals with the development of a dimensional rock sawing machine to optimize production small-volume stone products in limestone quarries by re-thinking use and transport equipment. A low-volume mining transportation adapter be developed for both can reduce number machines used mine. After cutting around block stone, material moved help machine. Cutting tests were performed determine w...

The mineralogical complexity of mine dust complicates exposure monitoring methods for occupational, respirable hazards. Improved understanding the variability in characteristics, e.g., mineral phase occurrence and composition, is required to advance on-site techniques that can be applied across diverse mining sectors. Principal components analysis (PCA) models were separately XRD FTIR datasets ...

In decades, various studies on passive treatment methods of acid mine drainage (AMD) have been actively conducted in order to reduce the cost AMD treatment. Open limestone channel is one most common and has already implemented mainly overseas. On other hand, it difficult secure large channels Japan due its topography, we need consider use alkaline materials with higher neutralization potential ...

Septic tanks are the second largest source of groundwater nitrate contamination in Nebraska. In this study, the feasibility of coupling a conventional lateral field with a sulfur/limestone layer to treat nitrate in septic tank effluent was investigated using column reactors to simulate the septic tank soil adsorption system. The effects of different hydraulic loading rates, nitrogen loading rat...

The Yanzhou coalfield is an important coal production base in north China, wherein a huge amount of mine drainage has occurred; however, there been relatively little research on the multi-layer groundwater system. In this study, Dongtan Coal Mine was considered as object and total 95 samples were collected. Furthermore, hydrogeochemical statistical methods employed to better understand characte...

This paper presents the results of an experimental study on the effect of limestone powder on the compressive strength, tensile behavior, and micromechanical parameters of a highly ductile cement composite incorporating limestone powder. Four mixtures were determined according to the replacement ratio of cement with limestone powder. A series of experiments including compressive strength, uniax...
