1. Study of nanocomposites with carbon nanotubes and their tendency for carbon organization
Abstract The carbon derived from the thermal treatment of modified phenolic resins (PR) tends to organize into graphitic lamellae or turbostratic carbon and is commonly considered non-graphitizable. In this study, nanocomposites were synthesized with modified phenolic resin (Novolac) used as the matrix and oxidized multi-walled carbon nanotubes (NTox) in amo

2. Flexible pavement with mining waste proposal - execution and analysis of an experimental section
Abstract The extraction of iron ore has a fundamental role in the Brazilian economy. However, such activity generates considerable volumes of waste whose disposal, even if regulated and licensed, has a significant environmental impact. The worldwide concern for sustainable practices along with the urgency for measures to mitigate environmental damage, justif

3. A New Dawn for Brazilian Pediatric Cardiac Surgery Is on the Way - Issues Around and Outside the Operating Room
ABSTRACT In some developing countries, congenital heart disease still stands out among the leading causes of death in the first year of life. Therefore, there is a great need to develop programs designed to improve outcomes in the diagnosis and surgical treatment of congenital heart disease in these nations, where children have always been and still are seve

4. Three-dimensional reconstruction and intraoperative ultrasonography: Crucial tools to safely approach highly complex renal masses
ABSTRACT Purpose: Robot-assisted partial nephrectomy (RAPN) is rapidly increasing its role in the nephron-sparing surgery setting (1). The recent introduction of technological advancements is leading more experienced surgeons to approach complex renal mass with a conservative intent (2, 3). In particular, three-dimensional reconstruction and the use of intr

5. Magnetic concentration route for recovering pellet feed fines stored in a mining dam
Abstract The greatest and noblest challenge of mining engineering for the present and the future of iron ore treatment could be considered as the pursuit of optimizing the use of mineral resources. The use of mining tailings, in the mineral sector itself, or in another industrial branch, meets the needs of circular economy as it increases the useful service

6. Effects of the addition of graphene on the compressive strength of geopolymeric mortar developed from k-feldspar mining waste
Abstract Contemporary organizations are showing a growing interest in the reuse of solid waste from industrial processes with the intention of reducing environmental impacts and reducing costs. The mining activity is one of the main waste generators in Brazil. In parallel, geopolymeric materials have been gaining prominence in studies that make it a possible

7. Physical and sensory characteristics of salty cereal bar with different binding agents
Abstract The purpose of this study was to evaluate different binding agents for the preparation of salty cereal bars and to characterize them regarding their physical and sensory parameters. Four formulations of cereal bars were developed using collagen, guar gum, xanthan gum and psyllium as binders, which were evaluated for instrumental color and texture. T

8. Dermoscopy of crusted lesion: diagnostic challenge and choice of technique for the analysis
Abstract The study of skin, the science of dermatology, has undergone significant transformations throughout the centuries. From the first descriptions of skin diseases in Egyptian papyri and in Hippocratic writings to the first treatises on dermatology, important individuals and discoveries have marked the specialty. In the 18th and 19th centuries, the spec

Abstract After natural fermentation and solar drying, sour cassava starch acquires expansion property. Traditionally, solar drying occurs without protection, and consequently physical contamination can arise. Thus, the aim of this study was to produce sour cassava starch using a low-cost solar dryer to prevent contamination, whilst retaining the expansion pr

11. Quality properties of doughs and noodles using chayotextle (Sechiem edule) flours
Abstract The quality and physicochemical properties of dough and noodles made from blends of chayotextle flour and wheat semolina were investigated. The results showed that the inclusion of chayotextle flour increased both the hardness and adhesiveness of the dough, and there was a 10% increase in cohesiveness and elasticity when using this particular flour.

12. Diseases and disorders associated with different stages of crop development and factors that determine the incidence in Hass avocado crops
ABSTRACT Hass avocado production systems in Colombia have increased to become the third largest area planted for fruit production. A number of factors that limit productivity such as diseases have become of high economic importance. The objectives of this study were to identify the causal agents associated with pathologies in Hass avocado crops in different
