1. Steel desulfurization on RH degasser: physical and mathematical modeling
Abstract Due to the high-quality steel demand, especially for ultra-low Sulfur steel, RH desulfurization has been practiced. Based on this, mathematical and physical modeling have been applied to study steel desulfurization by reagent addition in the RH degasser vacuum chamber. The main result of cold modeling, using water and oil emulating steel and slag, r

2. A Simple and Efficient Optimized Solid-Liquid Extraction with Low Temperature Partition Procedure for Dissipation and Translocation Study of Pesticide Residues in Rice Grains
Pesticides are used globally to protect food against pest attack. This study evaluates the dissipation of bifenthrin and deltamethrin residues in unhulled rice and the translocation of these insecticide residues in husked rice stored at 25 °C in a biochemical oxygen demand (BOD) incubator for 35 days. For pesticide determination, the simple and efficient so

3. CALIBRATION OF THE THERMAL DISSIPATION PROBE FOR ATEMOYA: (Annona squamosa x A. cherimola)
ABSTRACT When determining plant transpiration (TR) using the thermal dissipation probe method, it is necessary to calibrate the sap flow (SF) estimation equation for each species under study, and thus obtain reliable information about the water demand of crops. This study aims to calibrate the equation used to determine SF using the thermal dissipation probe

5. Retrospective study of allometric relationship between heart rate, electrocardiographic parameters and bodyweight in dogs
RESUMO A relação alométrica entre peso corporal (PC) e frequência cardíaca (FC) foi descrita como inversamente proporcional em animais domésticos, mas isso tem sido refutado. A relação entre FC e variáveis eletrocardiográficas é descrita na literatura. No entanto, estudos sobre a variação e a influência de fatores nos parâmetros hemodinâmicos

6. Thermal Dissipation Effect on Temperature-controlled Friction Stir Welding
Resumo Durante a Soldagem por Fricção linear (FSW) de geometrias complexas, a dissipação térmica, induzida por características geométricas ou pelo ambiente circundante, desempenha um papel importante na qualidade final da junta. Para garantir uma qualidade consistente em condições diferentes é necessário a adaptacão de parâmetros durante o proce

7. LEAF TEMPERATURE AND TRANSPIRATION OF PEQUI TREES WITH AND WITHOUT WATER RESTRICTION
ABSTRACT The answers to when and how much to irrigate orchards can be obtained based on the measurements of plants' transpiration and leaf temperature. This study aims to determine the leaf temperature and sap flow of the pequi tree (Caryocar brasiliense Camb.), both with and without water restriction. Further, the leaf temperature was measured by infrared t

8. Flexure Based Energy Dissipating Device in Self-Centering Braces
Abstract Self-centering braces, in the current stage of development can accommodate large deformation and force levels. However, there is still a need for improvement of the energy dissipation mechanisms commonly incorporated in these braces. Yield based energy dissipation systems can overcome some of the problems faced with friction-based devices, such as s

10. Evaluation of the Projectile's loss of Energy in Polyester Composite Reinforced with Fique Fiber and Fabric
Firearms threat has always been a matter of personal concern, especially to soldiers in armed conflicts as well as police officers and civilians involved with public security. A multilayered armor system (MAS) is intended to personal protection against high kinetic energy ammunition, such as that used in rifles. MAS layers are normally composed of a front ce

11. Foliar application of silicon decreases wheat blast symptoms without impairing photosynthesis
ABSTRACT Considering the importance of blast, caused by Pyricularia oryzae, to impact wheat yield, this study investigated whether the foliar spray of potassium silicate (PS) could affect the photosynthesis of wheat plants and its potential to reduce disease symptoms. The Exp. 1 aimed to determine the effect of the foliar spray of PS on the photosynthetic pe

12. ENERGETIC ANALYSIS OF AN ABSORPTION CHILLER USING NH3/LiNO3 AS AN ALTERNATIVE WORKING FLUID
Abstract This paper presents a thermodynamic model developed for a prototype absorption chiller using NH3/LiNO3 with 10 kW of nominal capacity. The study was undertaken using thermodynamic modeling based on the mass and energy balance, takes the overall heat transfer coefficients into consideration and uses the characteristic equation method. First, the resu
