2. Bibliometric Analysis for Pattern Exploration in Worldwide Digital Soil Mapping Publications
Abstract Bibliometric analyses provide a clear understanding of the scientific performance and relate them with standards of the global scientific production. Soil science is an outstanding and developing field among environmental sciences. Knowledge about soil characteristics and their distribution in the environment has been enriched by the use of new geot

3. Generation of a triple-fluorescent mouse strain allows a dynamic and spatial visualization of different liver phagocytes in vivo
ABSTRACT Resident and circulating immune cells have been extensively studied due to their almost ubiquitous role in cell biology. Despite their classification under the “immune cell department”, it is becoming increasingly clear that these cells are involved in many different non-immune related phenomena, including fetus development, vascular formation,

4. Noncontact three-dimensional evaluation of surface alterations and wear in NiTi endodontic instruments
Abstract The aim of this study was to undertake a qualitative and quantitative assessment of nanoscale alterations and wear on the surfaces of nickel-titanium (NiTi) endodontic instruments, before and after use, through a high-resolution, noncontact, three-dimensional optical profiler, and to verify the accuracy of the evaluation method. Cutting blade surfac

5. A conceptual framework for a sports knee injury performance profile (SKIPP) and return to activity criteria (RTAC)
ABSTRACTInjuries to the knee, including intra-articular fractures, ligamentous ruptures, and meniscal and articular cartilage lesions, are commonplace within sports. Despite advancements in surgical techniques and enhanced rehabilitation, athletes returning to cutting, pivoting, and jumping sports after a knee injury are at greater risk of sustaining a secon

6. Bryophyte flora in upland forests at different successional stages and in the various strata of host trees in northeastern Pará, Brazil
In the northeastern region of the Brazilian state of Pará, approximately 90% of the forested areas are secondary forests. Secondary forests are interesting areas for floristic studies aimed at determining the effects that clear-cutting has on bryophyte communities. The aim of this study was to compare upland forests at different successional stages and the

7. A grande dor das coisas que passaram: a recordação contemplativa na crônica de Rubem Braga.
The chronicle stands as a singular genre, especially for transiting between the fields of literature and journalism. Rubem Braga is considered one of the most representative chronicle writers in Brazilian literature, with a particular condition of being a writer who gained notoriety for only writing literary chronicles. With an extensive chronicle production

8. Sexualidade humana e preconceito: do silêncio ao controle das condutas sexuais
The present dissertation aims to analyze the construction process of sexual prejudice, based on the sexual behavior of ancient civilizations and on the guidelines of sex education in Brazil. Based on the fundamentals of dialectical materialist approach, the daily life/attitude/social behavior are a basic element as a phenomenon; and the category possibility/

9. Métodos para resgate, conservação e multiplação em larga escala de matrizes de Eucalyptus benthamii Maiden &Cambage / Methods for rescue, conservation and multiplication of matrices Eucalyptus benthamii Maiden &Cambege
The E. benthamii presents a great aptitude for cultivation in Brazil, especially in cold climates and with frequent frosts, this is due to your west of Sydney origin in Australia, where temperatures are very low, with frosts. Taking into account their optimal silvicultural performance, selected genotypes will certainly represent an excellent alternative for

10. Design of a computer aided quick-stop device for study of dead metal zone formation
The use of quick-stop device allows observing a sequence of frozen images focused on the chip formation area when machining in orthogonal turning tests. This work records the development of a quick-stop device employing a servo motor. The present invention relates generally to a quick stop device, for combination with a cutting machine that is able to abrupt

11. Modelling and optimization of the surface roughness in the dry turning of the cold rolled alloyed steel using regression analysis
Surface quality of the machined parts is one of the most important product quality indicators and one of the most frequent customer requirements. The average surface roughness (Ra) represents a measure of the surface quality, and it is mostly influenced by the following cutting parameters: the cutting speed, the feed rate, and the depth of cut. Quantifying t

12. Capacidade de deterioração de cepas de Eucalyptus spp. por fungos xilófagos / Capacity of deterioration of stumps of Eucalyptus spp. by xylophagous fungi
On the reform of the forest stand, after the cutting of trees, the remaining strains of Eucalyptus spp. must be removed. The natural degradation of stumps of eucalypts after clear cutting is slow. The mechanical destock raises the cost of production, involves machinery traffic on the ground favoring soil compaction and hindering the growth and distribution o
