1. Unveiling the Bacterial Sesquiterpenome of Streptomyces sp. CBMAI 2042 Discloses Cyclases with Versatile Performances
Terpenes are the most abundant class of natural product that exist in nature. They possess a myriad of industrial applications including pharmaceutical, perfumery and flavors, bulk chemicals, and fuel. Intriguingly, until today, the vast majority of characterized terpenoids have been isolated from plants and fungi, and only in recent years bacteria were foun

4. Geostatistical simulations with heterotopic hard and soft data without modeling the linear model of coregionalization
Abstract Most mining decisions are based on models estimated/simulated given the information obtained from samples. During the exploration stage, samples are commonly taken using diamond drill holes which are accurate and precise. These samples are considered hard data. In the production stage, new samples are added. These last are cheaper and more abundant

5. Obtaining geotechnical parameters from correlations between geophysics and CPT tests in tailings dams
Abstract This article introduces a hassle-free methodology for geotechnical parameters to be obtained from correlations between geophysics and CPT field tests in tailings dams undergoing the decommissioning process, which are reasonably representative of site conditions, from the very early project stages, with extensive coverage of all impoundment parts, wi

6. Reconciliation of sampling data and heterogeneity analysis of a bauxite mine in Poços de Caldas/MG, in Brazil
Abstract Reconciliation plays a key role in controlling and analysing mine operations. It consists in comparing model estimates with actual results produced by the plant, being used as an indicator, a monitoring tool. Discrepancies between these values are common in the mining industry and they highlight problems during processing steps. However, these discr

8. Open stope stability assessment through artificial intelligence
Abstract Underground mining is a set of methods that allows the extraction of ore in depth, ensuring sustainability and economic viability. One of the problems that arise in underground mine operations is open stope stability. The method for assessing stabil ity of open stopes is the stability graph proposed by Mathews et al. (1981). It is possible to estima

9. Detection of seepage paths in small earth dams using the self-potential method (SP)
Abstract The application of geoelectric methods, such as induced polarization (IP), the electrical resistivity and the self-potential (SP), presents an important indirect study methodology in several areas of geology, such as mining, geotechnics and environmental geology. The present study deals with the results of the application of the self-potential metho

11. Correlations of rock mass classifications applied to ferruginous caves
Abstract For the Brazilian iron ore mines, the presence of caves presents a challenge, since most of them are located within the ore deposit. The National Environment Commission (CONAMA 347 Resolution/2004) establishes that the speleological heritage, as well as its area of influence, cannot sustain irreversible environmental impacts. The physical integrity
