2. IMPROVEMENT OF METHANE STORAGE CAPACITY IN ACTIVATED CARBON BED WITH BIDISPERSE PACKING
Abstract This study presents a numerical investigation of the dynamics of methane adsorption in granular activated carbon beds with bidisperse packing in order to reduce the void spaces between the adsorbent particles and to improve the storage capacity in adsorbed natural gas vessels. Two distinct particle sizes (d and D) were used for the packing of the bi

3. The electric boat charging problem
Abstract Paper aims This paper studies a new optimization problem called the Electric Boat Charging Problem (EBCP), which is based on the application of electric mobility in a river transport operation problem. Originality This work pioneers the studies of the electric mobility on the river operations, by proposing the EBCP. This problem includes real feat

4. Bulk water charges in the dairy industry: A case study of interstate basins in Minas Gerais, Brazil
RESUMO: A água é um insumo essencial para qualquer agroindústria, utilizada para diversas finalidades, como em procedimentos de higienização, trocadores de calor e formulação de bebidas. Dessa forma, a cobrança pelo uso da água bruta, regulamentada no Brasil pela Política Nacional de Recursos Hídricos - Lei nº 9.433/97 e leis estaduais, é um te

7. Study of Electric charge induction with a three-dimensional model using the finite elements method
Abstract One of the first subjects studied in Electricity and Magnetism classes is how one can make an electrically neutral object be an electrically charged object. There are three ways to do it: charging by friction, charging by contact and charging by induction. Induction charging is a method used to charge an object without actually touching the object t

8. In Situ Synchrotron Radiation Measurements During Axial Strain In Hydrogen Cathodically Charged Duplex Stainless Steel SAF 2205
The objective of this work is the evaluation of hydrogen effects on the martensitic transformation and strain hardening in Duplex Stainless Steels (DSS) SAF 2205 (UNS S32205/S31803). DSS are two-phase alloys (austenite and ferrite), which are used for applications requiring high mechanical strength, in corrosive environments. Therefore, it is necessary a bet

9. A PROPOSAL FOR A TYPOLOGY OF SHARING ECONOMY
ABSTRACT Purpose: to propose a typology for sharing economy that allows the characterization and classification of its main forms of manifestation. Originality/value: the theme that involves collaborative consumption and sharing economy has wide definitions with no clear establishment of boundaries between them. Part of that definition gap may occur becaus

10. Liposomes as potential carriers for ketorolac ophthalmic delivery: formulation and stability issues
ABSTRACT Drug delivery to treat ocular disorders locally is a challenging endeavor. Traditional ocular dosage form - eye drops - exhibits poor availability, consequently inefficient therapeutic response. The objective of the study was to formulate and characterize a ketorolac tromethamine ocular system with a prolonged release pattern based on liposomes as a

11. Optimization of spray deposition and Tetranychus urticae control with air assisted and electrostatic sprayer
ABSTRACT: Improved spray deposition can be attained by electrostatically charging spray droplets, which increases the attraction of droplets to plants and decreases operator exposure to pesticide and losses to the environment. However, this technique alone is not sufficient to achieve desirable penetration of the spray solution into the crop canopy; thus, ai

12. ANALYSIS OF A COMMERCIAL PORTABLE LITHIUM-ION BATTERY UNDER LOW CURRENT CHARGE-DISCHARGE CYCLES
The dependence between the transferred charge and the corresponding transference time to charge and discharge a portable cell phone Li-ion battery (LiCoO2/C) under cycles of low intensity currents was studied in detail. The voltage curve profile between 3.0 and 4.2 V and the charging and discharging time are strongly influenced by the applied current intensi
