1. Efficient Encapsulation and Controlled Release of N,N-Diethyl-3-methylbenzamide (DEET) from Oil-in-Water Emulsions Stabilized by Cationic Nanocellulose and Silica Nanoparticles
Oil-in-water emulsions containing N,N-diethyl-3-methylbenzamide (DEET) were developed aiming to extend the sustained release of the active compound, by using two oppositely charged nanomaterials, namely silica nanoparticles (SiNP) and cationic cellulose nanofibrils (CCNF), as stabilizers, and a mixture of food-grade nonionic surfactants to avoid precipitatio

2. Trends in consuming alcoholic beverages among adolescents and young adults of school age: sexes differences
Abstract Objective: To analyze the tendency of alcoholic beverage consumption among adolescents and young adults at school age according to their sexes. Methods: This is a trend research study in public schools of the municipality of Petrolina, between 2014 and 2016, with 3146 students aged between 12 and 24 years old. The instrument was constituted by soc

3. Aortic Valve Repair as a Subspecialty: Still an Institutional Practice or Open for All?
ABSTRACT Aortic valve repair combined with root stabilization procedures have been reported to have reliable mid to long-term outcomes, and this is one of the reasons that various surgical units are accepting these techniques as an option in selected cases. Aortic valve replacement is a standard procedure with established results, but to master its technique

4. Immunoadsorption therapy for a meningococcemia patient with myocarditis, adrenal hemorrhage, and purpura fulminans: a case report
Abstract Neisseria meningitidis, also known as meningococcus, is a relatively uncommon cause of invasive infection, but when it occurs, it is frequently severe and potentially life-threatening. A ten-year-old female patient developed a purpuric rash with fever. Upon arrival to the pediatric intensive care department, she was unconscious and in a poor general

5. Granulometric stabilization of laterites from Triângulo Mineiro and Alto Paranaíba for use in base course
Abstract The present article presents the study of three laterites from the Triãngulo Mineiro and Alto Paranaíba region, aiming to use it as a pavement base. The methodology used consisted of carrying out the tests prescribed by the DNIT 098/2007 standard and, as a complementary methodology, linear contraction, MCT classification, modulus of resilience and

6. Spectroscopic techniques combined with chemometrics to study organic matter in tropical soils with different degrees of pedogenetic evolution
Understanding of the organomineral interactions in soil can elucidate the humic substances (HS) formation and the humification process. This study aimed to structurally characterize the humic acids (HA) formed in tropical soils with different pedogenesis degrees. The HA fraction was extracted from soil samples in the superficial horizons of an Inceptisol and

7. Effect of continuous intra-incisional bupivacaine on postoperative pain in non-traumatic spinal fixation surgeries: a randomized controlled trial
Abstract Background Continuous injection of local anesthetics by using surgical wound catheters for postoperative pain relief has gained acceptance in recent years. However, whether this method can be alternatively used instead of systemic opioids in different surgical procedures has not yet been elucidated. Objectives The aim was to investigate the effect

8. Custom-made finger splint versus prefabricated finger splint: finger flexion stabilization
SUMMARY OBJECTIVE: Finger splints are used as a treatment option in tendon, bone, and soft tissue injuries. For immobilization, custom-made splints and prefabricated finger splints are used. In splints made for immobilization, it is aimed to limit joint movement. The aim of our study is to reveal how much custom-made splints and prefabricated finger splints

9. Soil stabilization with lime for erosion control in solar plants
Abstract The installation of solar parks requires extensive areas and results in soil erosion in many cases. One suitable solution is applying lime to improve soil characteristics, such as mechanical strength, stability, workability, durability, and internal and surface erosion resistance. This soil treatment is of particular importance when dealing with hyd

10. The Stabilization of Asphaltenes in Different Crude Fractions: A Molecular Approach
The conditions of petroleum extraction may allow asphaltenes to precipitate, causing deposition that clogs wells, pipes and equipment, consequently reducing productivity. In this work, the solubility parameters and precipitation onset of polar fractions of heavy crudes from Brazilian fields were estimated using a simplified system of n-heptane/toluene mixtur

11. THE EXPLORATORY DIMENSION OF FMRI EXPERIMENTS
Abstract Driven by an appreciation of the field’s early stage of development, I apply the concept of exploratory experimentation, originally put forward in the late 90s philosophy of biology, to current research in cognitive neuroscience. I concentrate on functional magnetic resonance imaging and how this wide-spread technique is used, from experimental de

12. Orofacial characteristics of the very low-birth-weight preterm infants
Abstract Objective: To evaluate the orofacial characteristics of very low-birth-weight preterm infants through anthropometric facial measures, orofacial anteroposterior analysis and the relationship between the gum pads. Method: Orofacial examinations was performed in 154 infants, classified into two groups: Group A comprised 54 very low-birth-weight infan
