1. Geochemistry and Spatial Variability of Rare Earth Elements in Soils under Different Geological and Climate Patterns of the Brazilian Northeast
ABSTRACT Growth in the agricultural and industrial sectors has increased the demand for rare earth elements (REEs) in the production of technological devices and fertilizers. Thus, the accumulation of these elements in the soil has become an environmental concern. Here, we aim to determine the natural contents of REEs in soils derived from different parent m

2. Inducible cellulase production from an organic solvent tolerant Bacillus sp. SV1 and evolutionary divergence of endoglucanase in different species of the genus Bacillus
Abstract Bacteria are important sources of cellulases with various industrial and biotechnological applications. In view of this, a non-hemolytic bacterial strain, tolerant to various environmental pollutants (heavy metals and organic solvents), showing high cellulolytic index (7.89) was isolated from cattle shed soil and identified as Bacillus sp. SV1 (99.2

3. Geology, geochemistry and petrology of basalts from Paraná Continental Magmatic Province in the Araguari, Uberlândia, Uberaba and Sacramento regions, Minas Gerais state, Brazil
Abstract: This study covers the region between the cities of Sacramento and Araguari/Uberlândia (Minas Gerais State, Brazil), where basalt flows from the Paraná Continental Magmatic Province outcrop. The investigated rocks present tholeiitic signature, with high titanium content, and are classified as Pitanga magma-type. The preserved basalt thickness is b

4. The potential role of Th17 lymphocytes in patients with psoriasis
Abstract: Background: Psoriasis is a chronic inflammatory disorder, characterized by increased keratinocyte proliferation due to abnormal differentiation of basal keratinocytes. The etiology of the disease is unclear, and according to the survey results, it is hypothesized that a combination of genetic and environmental factors prompts an abnormal immune re

5. The microbiological signature of human cutaneous leishmaniasis lesions exhibits restricted bacterial diversity compared to healthy skin
Localised cutaneous leishmaniasis (LCL) is the most common form of cutaneous leishmaniasis characterised by single or multiple painless chronic ulcers, which commonly presents with secondary bacterial infection. Previous culture-based studies have found staphylococci, streptococci, and opportunistic pathogenic bacteria in LCL lesions, but there have been no

6. Comparação da distribuição geográfica potencial de buriti, Mauritia flexuosa L. (araceae) gerada por diferentes modelos preditivos
Segundo a legislação brasileira, as Veredas (ecossistemas dominados por vegetação típica em solos alagados, com renques de palmeiras Buriti - Mauritia flexuosa) são consideradas áreas de preservação permanente, juntamente com as matas ciliares e demais formas de vegetação natural. Assim, Buriti é um elemento chave para identificar as Veredas, sen

7. Aplicações de mecânica estatística a especiação simpátrica e inferência aproximativa / Applications of statistical mechanics to sympatric speciation and aproximative inference
This thesis presents applications of the framework of Statistical Mechanics to two independent problems. The first corresponds to a computational model for the evolution of Assortative Mating in the Sympatric Speciation process; and the second a learning algorithm built by means of a Bayesian Inference approach. In the biological problem each individual in a

8. Modelagem espaço temporal do uso do solo e potencial de erosão no Vale do Ribeira / Spatio temporal modeling the soil use and potential of erosions in the Ribeira Valley
This paper comprises an experiment to map hidden patterns in multi-source data that could be associated with Pb geochemical soil anomalies. The study area is confined between the Apiaí Fold-Belt, hosts numerous Pb and Zn deposits; it was under the influence of regional Pb mining and Pb refinery factory activities until 1995; and exhibits soils enriched in P

9. Caracterização hidrogeológica do aquífero cauê, quadrilátero ferrífero, MG: Subsídios para a gestão dos recursos hídricos no quadrilátero ferrífero
The Cauê aquifer encompasses the geological unit that is the host of the Iron Quadrangle bodies of iron ore (Cauê formation). It has got significant hydrogeological potential, which is used for part of the water supply for Belo Horizontes metropolitan area, and has got a fundamental importance for the maintenance of the general environmental conditions of

10. Caracterização hidrogeoquímica da microbacia de drenagem do córrego Barra Bonita, São Paulo / Hydrogeochemistry characterization of the Barra Bonita stream small watershed, São Paulo
The study in the Barra Bonita stream small watershed (S: 22o 2553,9" and W: 48o 3234,8") aimed to characterize its hydrogeochemical parameters by dissolved and particulate material transport models to identify the relations between soil use and water quality. Because there was no longer an environmental zoning in the municipality of Barra Bonita, this study

11. Genome signature comparisons among prokaryote, plasmid, and mitochondrial DNA
Our basic observation is that each genome has a characteristic “signature” defined as the ratios between the observed dinucleotide frequencies and the frequencies expected if neighbors were chosen at random (dinucleotide relative abundances). The remarkable fact is that the signature is relatively constant throughout the genome; i.e., the patterns and le

12. Remodeling of Yeast Genome Expression in Response to Environmental Changes
We used genome-wide expression analysis to explore how gene expression in Saccharomyces cerevisiae is remodeled in response to various changes in extracellular environment, including changes in temperature, oxidation, nutrients, pH, and osmolarity. The results demonstrate that more than half of the genome is involved in various responses to environmenta
