The aim of this paper was to prepare, by the freeze-drying method, ionically crosslinked chitosan membranes with different contents pentasodium tripolyphosphate (TPP) and loaded 1,4-naphthoquinone (NQ14) drug, in order evaluate how physical crosslinking affects NQ14 release from for cancer therapy application. were characterized Fourier transform infrared spectroscopy (FTIR), wide-angle X-ray diffraction (WAXD), scanning electron microscopy (SEM), swelling degree, through vitro drug...
This study explores an innovative topical formulation to treat alopecia by encapsulating cannabidiol (CBD) in chitosan nanoparticles. CBD, widely known for its anti-inflammatory, antioxidant, and endocannabinoid-modulating effects, shows significant potential treating alopecia, a condition characterized hair loss influenced genetic, hormonal, or environmental factors. However, low water solubility presents challenge applications. To address this issue, nanoparticles were synthesized using of...
Pomegranate is a fruit desirable for its nutritional and medicinal properties which has great industrial potential that yet under-explored. Notable integral use, the peels are used in infusions seeds consumed without restrictions. In this sense, objective of work to determine drying kinetics pomegranate hot air circulation oven, at temperatures 50, 60, 70 °C, adjust mathematical models experimental data, effective diffusivities thermodynamic process physicochemical characteristics fresh...
Building information modelling (BIM) is the first step towards implementing 4.0, where virtual reality and digital twins are key elements. The use of unmanned aircraft systems (UAS/drones) to capture data from buildings nowadays a very popular method, so methodology was developed digitally integrate photogrammetric surveys building into BIM, exclusively with drones. Currently, responsible for 40% energy consumption in Europe; therefore, interconnection between BIM (BEM) essential digitalize...
For the purpose of renewable materials applications, Curauá fiber treated with 5% sodium hydroxide was added to high-density biopolyethylene, using an entirely Brazilian raw material sugarcane ethanol. Polyethylene grafted maleic anhydride used as a compatibilizer. With addition curauá fiber, crystallinity reduced, possibly due interactions in crystalline matrix. A positive thermal resistance effect observed for maximum degradation temperatures biocomposites. When (5% by weight), morphology...
Know the hygienic and sanitary conditions of kitchens Public School Units in a Regional City Fortaleza, CE, Quantitative, descriptive study, with cross-sectional design. It was applied to checklist prepared accordance RDC 216/04 adapted reality school units. The highest non-compliance rates were relation absence shelf card (41.78%), lack equipment (55%), incomplete performance (38%) need for reform schools (51.18%). whether it is possible add more questions when checking - list focused on...
Wire Arc Additive Manufacturing (WAAM) is a process for fabricating metal parts known its high productivity and material flexibility. However, defects such as overheating, residual stresses, distortions, porosity, non-homogeneous microstructure limit commercial applications. Therefore, the present study aims to analyze correlation between electrical sensing anomalies in Gas Metal (GMA) during WAAM occurrence of microscopic caused by external contamination. To achieve this, experiments were...
This study aimed to develop and characterize biodegradable films made from pectin, pomegranate seed oil, different microalgae (Spirulina platensis, Chlorella sp., Scenedesmus obliquus) evaluate their applicability as packaging by verifying effect on the conservation postharvest quality of cajarana (Spondias dulcis). The proposed in this were assessed for physical, optical, mechanical attributes, well physicochemical characteristics fruits coated with after 14 days storage at 10 ± 1 °C...
O processo de secagem é comum em operações industriais para conservação alimentos. A forma geométrica elipsoidal e suas variações são encontradas produtos agrícolas, tais como: grãos arroz, trigo feijão. Neste sentido, este trabalho tem como objetivo prever a distribuição umidade no interior sólidos com formato durante o intermitente. Para tanto, utilizou-se método integral baseado Galerkin (método GBI) obter solução da equação difusão incorporando período têmpera na cinética Foram...
The objective of this study was to carry out a on continuous and intermittent drying (intermittency ratio α = 2/3) osmotically pretreated melon pieces, cut in the form parallelepiped. An osmotic dehydration pretreatment performed using an incubator with mechanical shaking. Drying processes were carried oven forced air circulation at temperatures 50 70 °C. data modeled by means empirical equations, order compare kinetics analyze impact process energy savings preservation bioactive compounds...
Glycerin-based fluids are proposed as a promising alternative to inhibited in the drilling of highly-reactive formations. However, even with use these fluids, it is still possible observe occurrence problems related balling drill bits and pipes, such agglomeration accretion cuttings. This study aims analyze how interaction between expandable minerals from reactive formations glycerin-based affects stability oil wells, focusing on extent phenomenon. For this purpose, bentonite pellets were...
