13. Investigating Space Radiation Environment Effects on Communication of Razaksat-1
ABSTRACT: This study attempted to identify whether space radiation sources could have affected the communication on RazakSAT-1 that was orbiting in a Low Earth Orbit-Near Equatorial (LEO-NEqO). Data on galactic cosmic rays (GCR), trapped protons, trapped electrons, and solar energetic particles (SEPs) obtained from Space Environment Information System (SPENV

14. Sequence-related amplified polymorphisms (SRAPs) reveal genetic diversity and variation regions in upland cotton (Gossypium hirsutum L.) in China
Abstract The lack of genetic diversity is an obstacle for genetic improvement of upland cotton in China; thus, new technologies must be developed to produce more polymorphic molecular markers associated with agricultural traits of the existing resources for breeding. A highly efficient and economical technology of sequence-related amplified polymorphism (SRA

15. Application challenges for information and automation technologies in an underground mine in Brazil
Abstract Organizations can establish a value-added sustainable strategy by increasing asset utilization. WLAN infrastructure in underground mines tends to be a consistent platform for reliability in data/information management, and assertive governance practices. It enables remote monitoring, registering and data transfer from a control room, avoiding unnece

16. CONTROL PROPOSAL FOR A HIGH PURITY COLUMN BASED ON THE SEPARATION OF VARIABLES BY THE INDEPENDENT COMPONENT ANALYSIS METHOD
Abstract Many industries are complex when it comes to operation mode. In order to reduce the problems related to strong coupling in these processes, the search for the incorporation of artificial intelligence devices has shown an increasing trend in recent years. Due to this complexity and control in multivariable processes, diagnosis and fault monitoring in

18. Early Open-Lung Ventilation Improves Clinical Outcomes in Patients with Left Cardiac Dysfunction Undergoing Off-Pump Coronary Artery Bypass: a Randomized Controlled Trial
Abstract Objective: To compare pulmonary function, functional capacity and clinical outcomes amongst three groups of patients with left ventricular dysfunction following off-pump coronary artery bypass, namely: 1) conventional mechanical ventilation (CMV); 2) late open lung strategy (L-OLS); and 3) early open lung strategy (E-OLS). Methods: Sixty-one patie

19. CONTINUOUS AND SEMICONTINUOUS REACTION SYSTEMS FOR HIGH-SOLIDS ENZYMATIC HYDROLYSIS OF LIGNOCELLULOSICS
Abstract An attractive operation strategy for the enzymatic hydrolysis of lignocellulosics results from dividing the process into three stages with complementary goals: continuous enzyme adsorption at low-solids loading (5% w/w) with recycling of the liquid phase; continuous liquefaction at high-solids content (up to 20% w/w); and, finally, continuous or sem

20. Online hybrid modeling method with application for predicting Bauxite production indicators
Abstract In the bauxite flotation process, concentrate grade and tailings grade are key production indicators; however, they are difficult to measure online. It is also difficult to develop an effective mathematical model for the process because of the complex non-linear and uncertain relationship among the feed parameters (feed grade, pulp density, slurry p

21. A Six Degrees-of-Freedom Flight Dynamics Simulation Tool of Launch Vehicles
ABSTRACT: The use of digital simulation has become an essential activity during the development and operation of launch vehicles, due to the complexity of such systems. Of particular interest is the flight dynamics simulation, which investigates the behavior of the vehicle in flight subjected to forces and moments. This work presents a simulation tool suited

22. Fortunas y adversidades del revisionismo: cine queer y Contracorriente
Revisionism and its metaphors seem to be a sign of the times. All throughout contemporary cultural production certain approaches are all too present: homages, pastiches, bricolages, parodies, appropriations, rewrites, among others. Not surprisingly, revisionist cultural genres have gain predominance, and specifically in cinema, the revisionist western-genre

24. Geração distribuída aplicada à edificações : edifícios de energia zero e o caso do laboratório de ensino da FEC-Unicamp / Distributed generation applied to buildings : net zero energy buildings and the case of the laboratory at FEC-Unicamp
Electricity consumption in Brazil increased 47% in the last decade, and it is estimated that it will increase 55.6% until 2020. Most of the electricity generated in the country is based on large hydroelectric dams, located away from the major cities. The planned expansion of the generation park to meet this increase in the demand is also based on this model,
