1. Forecasting mass and metallurgical balance at a gold processing plant using modern multivariate statistics
Abstract Knowing the quantity and the quality of products and tailings generated by a beneficiation plant, even before ore processing, can make the mining operations more sustainable, more profitable, and safer. To forecast these values, it is necessary to submit samples to batch tests which mimic the processing workflow used on an industrial scale. Then, th

2. Mudança dos elementos meteorológicos em função da degradação da floresta urbana
Resumo O estudo das interações biosfera-atmosfera permite descrever e caracterizar os principais processos de transferência de energia e massa, relacionados às particularidades da vegetação. Assim, as interações que ocorrem em uma floresta podem sofrer impactos significativos em virtude de mudanças do clima ou no uso do solo. Deste modo, o objetivo

5. Geochemical Signature of Amazon Tropical Rainforest Soils
ABSTRACT: Evaluating soil geochemical diversity in the Amazon Basin has been a challenge largely because most study sites have been at the edge of the basin and it is difficult to get samples in such a region. Here we show that even among the most weathered soils, physicochemical soil properties express lithology. Our results are based on topsoil samples col

6. The HPLC Fingerprint Analysis of Selected Cirsium Species with Aid of Chemometrics
Twelve Cirsium sp. methanolic extracts were analyzed using high-performance liquid chromatography gradient elution method with run time of 45 min. Four Kinetex (150 × 4.6 mm) chromatographic columns (C18 5 µm, C18 2.6 µm, pentafluorophenyl 5 µm, phenyl-hexyl 5 µm) and mobile phase consisting of methanol/water/formic acid 1% were used. Eight standards (n

7. Phenotype and cell proliferation activity of duct-like structures in human sublingual glands: a histological and immunohistochemical study
There are several age-related microscopic changes in the salivary glands, including the increase in the number of duct-like structures (DLS). However, the true origin and the phenotype of the DLS are not known. Objective To evaluate the phenotype and the cell proliferation index of the DLS of human sublingual glands. Material and Methods Sixty sublingual gla

8. Validation and reliability of a modified sphygmomanometer for the assessment of handgrip strength in Parkinson´s disease
BACKGROUND: Handgrip strength is currently considered a predictor of overall muscle strength and functional capacity. Therefore, it is important to find reliable and affordable instruments for this analysis, such as the modified sphygmomanometer test (MST). OBJECTIVES: To assess the concurrent criterion validity of the MST, to compare the MST with the Jamar

9. Can the adapted arcometer be used to assess the vertebral column in children?
BACKGROUND: The adapted arcometer has been validated for use in adults. However, its suitability for use in children can be questioned given the structural differences present in these populations. OBJECTIVE: To verify the concurrent validity, repeatability, and intra- and inter-reproducibility of the adapted arcometer for the measurement of the angles of t

10. Psoriasis severity and hypothalamic-pituitary-adrenal axis function: results from the CALIPSO study
Psoriasis is a chronic inflammatory disease that significantly impacts life quality, being associated with stress and mental disorders. We investigated whether the activity of the hypothalamic-pituitary-adrenal (HPA) axis was associated with psoriasis severity, daily life stress and anxiety, and depressive symptoms. In this ancillary study, which was part of

11. Marcadores do sistema hemostático e sua associação com parâmetros clínicos e laboratoriais em mulheres com síndrome dos ovários policísticos = : Markers of the hemostatic system and their association with clinical and laboratory parameters in women with polycystic ovary syndrome / Markers of the hemostatic system and their association with clinical and laboratory parameters in women with polycystic ovary syndrome
Introduction: Few studies have been conducted on hemostatic disorders in polycystic ovary syndrome (PCOS). In women with PCOS, thromboembolic risk factors such as obesity, hyperandrogenism and insulin resistance are often present, indirectly suggesting a greater probability of coagulation disorders. Objective: To evaluate some markers of the hemostatic syste

12. Qualidade da madeira de Eucalyptus para a produção de carvão vegetal / Wood quality of Eucalyptus for charcoal production
The present study aimed to determine the properties of wood and charcoal from different clones of Eucalyptus spp. Six clones at 7.5 years old were evaluated and the samples were from a clonal test of a forestry company, located in the city of Lassance, Minas Gerais, Brazil. For wood, basic density, heart/sapwood ratio, morphological analysis of fibers and po
