1. Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization
Abstract Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore modeling to honor the structural aspects that control the mineralization. The grade domains are de

2. Theoretical Calculations on the Mechanism of Hydrogenation of Diphenylacetylene over Pdn (n = 1-4) Clusters
Diphenylacetylene (DPA) is a precursor of stilbene and benzil, and reduction of DPA or its derivatives with metallic reagents is both an old and contemporary topic of research. By means of density function theory (DFT) calculations, a detailed investigation of the mechanism of the hydrogenation of DPA over Pd clusters was carried out at the molecular level.

3. Hypovitaminosis D, Low Bone Mineral Density, and Diabetes Mellitus as Probable Risk Factors for Benign Paroxysmal Positional Vertigo in the Elderly
Abstract Introduction Studies have found that elderly patients with benign paroxysmal positional vertigo (BPPV) may present low levels of vitamin D (25 (OH) D), changes in bone mineral density, and diabetes mellitus (DM). Objective To investigate the possible association between BPPV, bone mineral density, hypovitaminosis D, 25 (OH) D and DM. Methods The

4. Survival analysis and cut-off point to estimate the shelf life of refrigerated fish burgers
Abstract The consumption of fish in Brazil is below the world average. In order to change this scenario, considering the high nutritional value of this meat, one of the strategies is to turn fish into a convenient product, such as burgers. Since fish burgers are not yet established in the market, it requires investigation of the shelf life. To that end, surv

5. HEIDEGGERS ERLÄUTERUNG DER HÖLDERLINSCHEN DICHTUNG: DIE VERWANDLUNG DES BIOGRAPHISCHEN IM GEDICHTETEN
ABSTRACT I attempt to explain what Heidegger means by the expression “the transformation of the biographical data in the poem” in his elucidation of the Hölderlin’s hymn Remembrance. Many scholars of German literature are interested in the date of the hymn and in Hölderlin’s experience at that date, in order to interpret the hymn. In contrast to th

8. Breast Cancer Prediction Using Dominance-based Feature Filtering Approach: A Comparative Investigation in Machine Learning Archetype
Abstract Breast cancer is the most commonly witnessed cancer amongst women around the world. Computer aided diagnosis (CAD) have been playing a significant role in early detection of breast tumors hence to curb the overall mortality rate. This work presents an enhanced empirical study of impact of dominance-based filtering approach on performances of variou

12. Investigation of the effect of nozzle design on rheological bioprinting properties using computational fluid dynamics
ABSTRACT Bioprinting is the utilization of techniques derived from three-dimensional printing to generate complex biological structures which may replace natural tissues or organs. It employs high spatial resolution deposition of different cell types, growth factors and biomaterials. Those together form bioinks, which are the bioprinting inputs, analogously
