1. Household Infrared Technology as an Energy-Efficient Approach to Achieve C-Cπ Bond Construction Reactions
We examined the ability of short-wave infrared (IR) light in the λ1.5-3.0 μm region of the infrared emission spectrum to accomplish C-Cπ bond construction reaction between π-excessive azaheteroaromatic and different carbonyl substrates supported on a bentonitic clay catalyst in solventless condition via a three-component condensation reaction. Preliminar

2. Performance evaluation of GSA, SOS, ABC and ANN algorithms on linear and quadratic modelling of eggplant drying kinetic
Abstract In this study, kinetics of eggplant drying was modeled in the laboratory-scaled Food Drying Oven (FDO) with resistance heater was designed and manufactured. The temperature, energy consumption and drying time of FDO were recorded by keeping the temperature of at different temperatures as 40, 50 and 60 °C. These saved values were chosen as the input

4. Calibration of high-temperature furnace assemblies for experiments between 200 and 600 MPa with end-loaded piston-cylinder apparatuses
Abstract We present pressure calibration results for piston-cylinder –” and 1” high temperature furnace assemblies in the 200-600 MPa range aiming to expand its applicability to simulate upper crustal conditions. The furnace assemblies were made up by crushable MgO, graphite heater, pyrex glass spacer, and NaCl sleeve. Twenty-one experiments were carri

5. A Review of Using Conductive Composite Materials in Solving Lightening Strike and Ice Accumulation Problems in Aviation
ABSTRACT: There are many problems facing aircraft in the air during flight, such as lightning strikes and ice accumulation on aircraft surfaces. These problems usually reduce aircraft efficiency and lead to serious accidents and fatalities. However, the current protection systems used to solve these problems of aircraft represent excessive energy usage, a ha

7. OTIMIZAÇÃO MULTIVARIADA DE METODOLOGIA PARA DIGESTÃO DE MICROPARTÍCULAS POLIMÉRICAS CARREADORAS DE CÁTIONS METÁLICOS
There are not reports in the literature of digestion processes of metallic cation carrier microparticles. Multivariate experimental designs were utilized to ensure an appropriate digestion for further analysis by atomic absorption spectroscopy. It was used a heater plate and the polimeric degradation was evaluated utilizing an analyzer of total organic carbo

9. Registrador portátil de odorantes basado en la modulación de temperatura de un sensor mos comercial
A simple, portable and low-cost system for odor detection was developed using a single MOS commercial sensor and a microcontroller. The temperature modulation technique was implemented applying a DC signal pulse to the sensor heater by a bipolar transistor. Two odorant profiles, ethanol and acetic acid vapors, were obtained and distinguished based on their a

10. ESTUDO DE UM REATOR SOLAR HÍBRIDO PARA CURA ACELERADA DO CONCRETO EM ÁGUA MORNA. / STUDY OF A HYBRID SOLAR REACTOR FOR ACCELERATED CURING OF CONCRETE IN WARM WATER.
The Portland cement concrete material is the most consumed after the water worldwide due to their versatility molding, strength and durability as a structural material. The curing is the procedure that aims to keep the concrete saturated with water in their early ages and it is essential to ensure the reactions of cement hydration, promoting its consolidatio

11. Desenvolvimento e caracterizaÃÃo centesimal, microbiolÃgica e sensorial de hidrolisados protÃicos de tilÃpia do Nilo (Oreochromis niloticus) / Development and proximate, microbiological and sensory characterization of Nile tilapia (Oreochromis niloticus) protein hydrolyzed
The Nile tilapia is a specie that has been highlighted in recent years for various reasons, however, during their filleting there is a sub use of its chips, resulting in very rich protein sources waste that could be used in food. An alternative for these waste can be the development of protein hydrolyzed, which are constructed using enzymes that hydrolyze pr
