1. Characterization of Nanocellulose Obtained from Cereus Forbesii (a South American cactus)
Crystalline cellulose nanofibers are obtained from the bark of Cereus Forbesii, a cactus native to the arid areas of South America. The obtaining of cellulose nanofibers was carried out in several steps: pretreatment of the raw material, elimination of hemicellulose and lignin to obtain cellulose, and an acid hydrolysis of cellulose to obtain crystalline cel

2. Test-Retest Reliability of the Speech, Spatial and Qualities of Hearing Scale (SSQ) in Brazilian Portuguese
Abstract Introduction The Speech, Spatial and Qualities of Hearing Scale (SSQ) is a questionnaire designed to assess the auditory experience and quantify hearing disabilities in realistic communication situations, with particular attention to binaural hearing. Objective To determine the test-retest reliability of the SSQ in Brazilian Portuguese. Method

3. Strain-deformation Reconstruction of Carbon Fiber Composite Laminates Based on BP Neural Network
The Carbon Fiber Reinforced Polymer (CFRP) laminate structural components used in the aerospace and military domains require high precision and strong stability. Usually the deformation of these structural components is difficult to be measured directly during operation, but the deformation of the CFRP laminate structure can be reconstructed with strain info

4. [PROVISIONAL] Molecular characterization and transcription analysis of DNA methyltransferase genes in tomato (Solanum lycopersicum)
Abstract DNA methylation plays an important role in plant growth and development, gene expression regulation and maintenance of genome stability. However, only little information regarding development- or stress-related DNA methyltransferases (MTases) genes is available in tomato. Here, we report the analysis of nine tomato MTases which were categorized into

6. Physical stability of iron ore caves: geomechanical studies of a shallow underground cave in SE Brazil
Abstract Caves hosted in iron formations are attracting considerable interest due to their scientific and environmental value. Some of these caves are located in or near iron ore mine sites, which represent an important source of income to Brazil. However, the Brazilian legislation requires speleological studies that currently have an impact upon ore reserve

7. Organic cocoa extract -loaded surfactant-based systems intended to skin bioadhesion
ABSTRACT This study was to develop, characterize, and evaluate the physical-chemical stability, in vitro antioxidant activity and in vitro safety profile of liquid crystalline systems (LCS) and microemulsions (MEs) with and without organic cocoa (OC) extract. LCS stabilized by surfactant polyoxyethylene 20 cetyl ether, containing water and oleic acid were st

8. "Athletic Identity Measurement Scale": Translation, Adaptation and Validation for Brazil
Abstract The aim of this study was to translate, adapt and validate the version of the Athletic Identity Measurement Scale (AIMS) for Brazilian Portuguese. The methodological procedures were conducted according to international recommendations: translation, back-translation, review by a board of experts, empirical fieldwork testing and inferential statistica

9. Target-directed catalytic metallodrugs
Most drugs function by binding reversibly to specific biological targets, and therapeutic effects generally require saturation of these targets. One means of decreasing required drug concentrations is incorporation of reactive metal centers that elicit irreversible modification of targets. A common approach has been the design of artificial proteases/nucleas

10. Thermoplastic polyurethane synthesis using POSS as a chain modifier
In this study, thermoplastic polyurethanes (TPUs) were synthesized using the one-shot process in solution. To obtain the samples n-phenylaminopropyl polyhedric oligomeric silsesquioxane (POSS) was added as a chain modifier during the synthesis in four different amounts. The samples were characterized by infrared spectroscopy (FTIR), thermogravimetric analysi

11. Influência da integridade dos barorreceptores nos ajustes morfofuncionais cardíacos à hipertensão espontânea em ratos / Influence of baroreceptor integrity on cardiac morpho-functional adjustments to spontaneous hypertension in rats
It has been demonstrated that reduced baroreflex sensitivity is an independent marker of mortality risk. The arterial baroreflex plays an important role in the maintenance of the moment-to-moment stability of blood pressure (BP). Although the contribution of blood pressure variability (BPV) to cardiovascular morbidity and mortality is well established, the m

12. A dynamic extension for LgV controllers
A dynamic state feedback control structure is proposed in this paper. The scheme is conceived as an adaptive controller with the equilibrium in an LgV control law as the uncertain parameter, which allows the implementation of the controller for systems with unknown equilibrium. A new property of LgV controllers is given, and it is proven that this and other
