2. Shelf-life assessment of energy banana bar using acceleration method with critical moisture content approach
Abstract The shelf-life of the product need to be evaluated according to the commercialization of the product. Shelf-life assessment of the product can be done using acceleration method (Accelerated Shelf-life Testing) with critical moisture content approach. This research used the acceleration method to predict the expired date of the energy bar based banan

3. EFFECT OF WAVELET DE-NOISING ON THE CLASSIFICATION OF PIG BEHAVIOUR
ABSTRACT To efficiently eliminate the noise generated by the triaxial accelerometer when collecting pigs’ behavioural data, this paper adopted SNR and MSE as the indexes to evaluate the de-noising effect of pigs’ acceleration signal under various combinations of wavelet basis, decomposition layer, threshold rule and threshold function. Based on the optim

4. EFFECT OF THE DOWNWASH FLOW FIELD OF A SINGLE-ROTOR UAV ON DROPLET VELOCITY IN SUGARCANE PLANT PROTECTION
ABSTRACT Protecting against the main sugarcane diseases and insect pests requires good control at the base of the plant; therefore, higher droplet penetration is required during plant protection. The objectives of this research were to explore the movement mechanism of droplets in a sugarcane protection operation using a single-rotor unmanned aerial vehicle

6. GALILEO’S PENDULUM AS A MAGNETIC BALANCE FOR STUDYING CHEMICAL MAGNETISM AT HOME
A very simple, but rich experiment, encompassing a classical Galileo’s pendulum, has been devised to be performed at home, especially during the Covid-19 pandemics. The experiment uses a miniature supermagnet rod as the pendulum oscillating element suspended from a fixed sewing thread. Its physics can be fully investigated, allowing to study the oscillatio

7. USE OF INOCULUM IN BIODIGESTERS WITH CATTLE MANURE UNDER CONVENTIONAL AND ORGANIC PRODUCTION SYSTEMS
ABSTRACT One way of making livestock farming a more sustainable practice is to raise cattle organically. However, regardless of the production system, there is a generation of residues that can be converted into energy resources using biodigesters. This study aimed to evaluate the addition of inoculum in the anaerobic biodigestion of cattle manure under orga

8. Optimization of shells modeled using NURBS subjected to a dynamic loading condition
Abstract This study presents an optimization method for the thickness of shell elements subjected to dynamic loads. Structural analyses were carried out using the finite element method. The analyzed domains were modeled using NURBS, and meshes were generated using a transformation of the parametric domain into the geometric domain via a geometric function. T

9. Investigação da variação de pressão em sistemas de vazão lateral através do princípio de Bernoulli
Resumo Especificamente, investigamos a variação de pressão ocorrido em sistemas simples de vazão lateral através do princípio de Bernoulli. Tal sistema de fluido é definido por um escoamento interno e externo a um recipiente de área de secção transversal constante, através de um orifício localizado em sua lateral. O escoamento pode ser controlado

10. Seismic resistance performance of a utility tunnel in saline soil foundation based on new cementitious composite materials
Abstract Because soluble salt in saline soil dissolves with water, utility tunnels built in saline soil foundation are more likely to damage due to by groundwater and earthquake. In this study, new cementitious composite materials were developed by using slag, building gypsum, quicklime, and magnesia. The unconfined compressive strengths of the saline soil s

11. Políticas públicas de preservação do patrimônio histórico no Brasil. Três estudos de caso (1973-2016)
Resumo Cada governo federal no Brasil estabeleceu um sentido de preservação do patrimônio histórico nem sempre original. A concepção adotada pelas instituições responsáveis no interior do aparelho de Estado se fez acompanhar por outras defendidas por parte de seus funcionários. A burocracia, mantendo contato com os debates internacionais por meio d

12. Testing discrepancies in the measurement of the acceleration of gravity in a physical pendulum experiment
Abstract After analysing results on the measurement of the acceleration of gravity using a physical pendulum in our teaching laboratory, we found that the value reported by the students is always higher than the theoretical expectations. In this article we analyze critically some of the students hypotheses for such displacement, and we perform an investigati
