1. Fuzzy Modelling to Describe the Pollutant Concentration in Fluids
ABSTRACT The study of the concentration dynamics of a pollutant substance in a fluid is a classic problem of fluid mechanics given by the transport equation u t + cu x = 0, where u = u(x,t) denotes the pollutant concentration along a horizontal pipe of a fixed cross-section in the positive x direction at he time t > 0 and c represents the fluid propagation

3. MODELING SOIL WATER REDISTRIBUTION UNDER SURFACE DRIP IRRIGATION
ABSTRACT The main objective of this study was to develop a numerical model to simulate water distribution, and the shape of the wetted soil volume, resulting from a point source irrigation at the ground surface (dripper), given soil hydraulic properties and irrigation system parameters. The mathematical model was developed in Fortran 90 at the Department of

5. Mathematical Modeling And Numerical Simulation of Dropwise Condensation on an Inclined Circular Tube
ABSTRACT: Dropwise condensation can improve heat transfer process and, consequently, leads to considerable reduction in size and weight of condensers as well as improvement in the dehumidification process in many applications, especially in civil transport aircraft. It can also be used as an efficient cooling tool for electronics and electrical systems in ai

6. Higher Education Aviation Programs in Greece: A Missed Opportunity or a Challenge to Meet?
Abstract: The air transport industry in Greece has been experiencing a significant growth. However, higher education has missed so far this export opportunity. Public universities and technological educational institutes have very limited undergraduate offerings in the fields of aeronautical engineering and aircraft maintenance technology, respectively. Thes

7. SOA-BD: Service Oriented Architecture for Biomedical Devices
Introduction: The communication of information systems with biomedical devices has become complex not only due to the existence of several private communication protocols, but also to the immutable way that software is embedded into these devices. In this sense, this paper proposes a service-oriented architecture to access biomedical devices as a way to abst

8. Analysis for the presence of determinants involved in the transport of mercury across bacterial membrane from polluted water bodies of India
Abstract Mercury, which is ubiquitous and recalcitrant to biodegradation processes, threatens human health by escaping to the environment via various natural and anthropogenic activities. Non-biodegradability of mercury pollutants has necessitated the development and implementation of economic alternatives with promising potential to remove metals from the e

9. Structural and Thermo-mechanical Evaluation of Two Engineering Thermoplastic Polymers in Contact with Ethanol Fuel from Sugarcane
Special polymers have been used in the manufacture of storage structures and pipelines avoiding corrosive processes during ethanol fuel transport/storage. Therefore, this work investigated comparatively the effects of the ethanol on the physical-mechanical properties of poly (ether ether ketone) (PEEK) and polyamide 11 (PA-11) based on ageing tests. The WAXD

10. Aperfeiçoamento da fermentação de sacarose através da modificação da expressão dos genes SUC2 e AGT1 em linhagens diploides de Saccharomyces cerevisiae. / Improvement of sucrose fermentation by modifying the expression of SUC2 and AGT1 genes in diploid Saccharomyces cerevisiae strains.
Currently, the S. cerevisiae strains used in industrial production of fuel alcohol in Brazil are diploid yeasts that of metabolize sucrose through its extracellular hydrolysis by the periplasmic invertase, followed by the transport of the formed glucose and fructose into the cells, and further metabolism through glycolysis. In this study, utilizing genetic e

12. An overview of lignin metabolism and its effect on biomass recalcitrance
Lignin, after cellulose, is the second most abundant biopolymer on Earth, accounting for 30% of the organic carbon in the biosphere. It is considered an important evolutionary adaptation of plants during their transition from the aquatic environment to land, since it bestowed the early tracheophytes with physical support to stand upright and enabled long-dis
