In this paper we present a novel Point-based pattern analysis for predicting Cassiterite (tin-ore) as a secondary mineral deposit in the Plateau Younger Granite Region of Nigeria (PYGR) using statistics, spatial analysis and machine learning techniques. Existing mining data points collected from field survey in the PYGR and the geological map of the region were digitized and converted into shap...

The prevalence of chronic kidney disease (CKD) is increasing, and CKD patients are at risk for severe adverse outcomes such as progressive loss of kidney function, cardiovascular (CV) disease, and premature death [1]. CKD-Mineral and Bone Disorder (CKD-MBD) is the clinical syndrome that develops as a systemic disorder of bone and mineral metabolism due to CKD, which is manifested by abnormaliti...

This study investigates the influence of microbes on fluid transport in sedimentary and igneous host rock environments. It particularly focuses on granodiorite rock (Äspö; Sweden) and mudstone (Horonobe; Japan) that were utilised during laboratory-based column experiments. The results showed that biofilms form on both rock types in low nutrient conditions. Cryogenic scanning electron microscopy...

One unresolved issue in geomicrobiology is the involvement of microbial activity in the formation of secondary mineral deposits, or speleothems, in caves. Although there is extensive literature demonstrating the importance of bacteria in the precipitation of calcite in noncave environments, the role that these organisms play within caves remains unclear. Evidence in support of microbial involve...

BACKGROUND Low bone mineral density (BMD) is common in chronic lung diseases and associated with reduced quality of life. Little is known about BMD in pulmonary hypertension (PH). METHODS Steroid-naïve patients with PH (n=34; 19 idiopathic, 15 chronic thromboembolic) had BMD measured by DXA at the time of diagnostic right heart catheterization. Exercise capacity, quality of life and various p...

Normophosphatemia and normocalcemia are maintained in chronic kidney disease (CKD) by increased levels of fibroblast growth factor-23 (FGF-23) and parathyroid hormone (PTH), but the stimuli for secretion of these hormones in early CKD are incompletely understood. Most human physiologic studies have focused on random or fasting measurements of phosphorus, calcium, FGF-23, and PTH, but in this st...

nakhlak lead mine is located at the nakhlak mountain 55 km ne of anarak town in isfahan province. the mineralogy is simple; galena and barite are the main primary minerals and cerussite is the main secondary mineral. sphalerite, pyrite, chalcopyrite, tetrahedrite-tennantite and acanthite occur as minor and trace mineral inclusions in galena. secondary minerals are anglesite, plattnerite, wulfen...
