61. Food content on children movies from 2013 to 2018: taking food processing into account
Abstract Objective Movies and TV programs directed to children contain food information that can potentially negative influence their food consumption. The NOVA classification is a useful system for monitoring food informational environment. Therefore, this study aimed to evaluate food content on children movies using the NOVA classification. Methods The 1

62. Multi-stage dumping sequence - a feasible waste management alternative for open pit mining
Abstract Waste management and environmental aspects are progressively gathering attention in the mining industry. Mine planners must deal with increasingly complex tasks to balance between ore block schedules, waste disposal, operational cost and environmental reclamation. The mine incomes are generally related to mining and processing of the ore, thus most

63. Astaxanthin Recovery from Shrimp Residue by Solvent Ethanol Extraction Using Choline Chloride:Glycerol Deep Eutectic Solvent as Adjuvant
The present study investigated the use of choline chloride:glycerol deep eutectic solvent as an adjuvant for tuning the ethanol extraction of astaxanthin from Litopenaeus vannamei processing residues. The adjuvant concentration did not show a clear trend on the total carotenoid, however, the addition of adjuvant proved to be advantageous in the ultrasound-as

64. QUANTIFICAÇÃO DE MULLITA PROVENIENTE DE RESÍDUOS DE CAULIM DA REGIÃO AMAZÔNICA: USO DO MÉTODO DE RIETVELD
Mullite is used to obtain a refractory material, there are several factors that influence the synthesis process of mullite: the preparation of the mixture, the precipitation and the reaction of SiO2 and Al2O3. For the synthesis of mullite, samples of kaolin processing residues were used as precursor material, because it presents SiO2 and Al2O3 in its composi

65. Synthesis of a Homologous Series of Trialkyl Arsines (C3-C12) and Applications of Arsenic Triiodide as a Synthetic Precursor
This work presents some modifications in the post-synthetic processing for a classical arsenic reagent: AsI3. In comparison with the widely used analog, the trichloride, arsenic triiodide presents several advantages such as low toxicity, air stability, and low volatility. It was used as a synthetic precursor in the preparation of a variety of arsenic(III) de

66. Storage of markies cultivar potatoes for prossessing
ABSTRACT The refrigerated induce the sweetening of the potato, which results in the dark color. The objective of this study was to determine the temperature and shelf life of Markies potato tubers under refrigerated storage for the processing of French fries. The levels of total soluble sugar (TSS), reducing sugars (RS), peroxidase (POD) and polyphenoloxidas

67. Freeze-casting applied to ceramic materials: a short review of the influence of processing parameters
Abstract In recent years there is a high interest in the freeze-casting process because it is a simple, economical, and environmentally friendly method for obtaining highly porous materials. Most of the materials obtained by this technique have directional pore structure and anisotropic properties. However, a wide range of pore size and morphology can be obt

68. Effects of processing and packaging on bioactive compounds of curriola jelly [Pouteria ramiflora (Mart.) Radlk.] during storage
Abstract The objective herein was to evaluate the effect of processing, packaging type (with and without exposure to light) and storage time on the quality of functional attributes of jelly prepared from curriola pulp. The experimental design was a completely randomized 2 × 5 factorial design, with two levels of packaging (transparent and amber) and five st

69. Autologous blood salvage in cardiac surgery: clinical evaluation, efficacy and levels of residual heparin
ABSTRACT Objective: Intraoperative blood salvage (cell saver technique) in cardiac surgery is universally used in surgical procedures with a marked risk of blood loss. The primary objectives of this study were to determine the concentration of residual heparin in the final product that is reinfused into the patient in the operating room and to evaluate the

70. Cold sintering and electric characterization of ZnO-BaTiO3 composites
Abstract The sintering is an essential step in the processing of ceramics materials. A number of researchers have reported new techniques for sintering. However, in general, the process still demands high temperatures. This paper reports the results of the cold sintering of ZnO-BaTiO3 composites. The microstructural, structural, and electric properties of th
