25. Modern High-Yielding Maize, Wheat and Soybean Cultivars in Response to Gypsum and Lime Application on No-Till Oxisol
ABSTRACT Modern maize, wheat, and soybean cultivars are usually characterized by a short cycle, high shoot-root ratio, and high responsiveness to nutrient input. Continuous no-tillage management (NTS) frequently leads to a steep gradient in soil chemical quality with depth, thus decreasing yield under conditions of acid subsoil and water stress. This study a

26. AnaBioPlus: a new package for parameter estimation and simulation of bioprocesses
Abstract A very important step in the study of bioprocesses is the modeling and simulation of bioreactors. This paper presents the AnaBioPlus software package, which was developed for teaching and research purposes concerning the analysis of bioreactors. The package consists of two programs: OptimusFerm and SimulaFerm. OptimusFerm allows the analysis of expe

27. Strategic Management in Hospitals: Tensions between the Managerial and Institutional Lens
Abstract The relationship between organizations and their environments has been object of study by scholars of the theory of organizations and in discussions concerning organizational strategy. When these perspectives come together, two sets of different but overlapping forces in the strategy formation process are highlighted. The purpose of this study is to

28. Enhanced ethanol production at commercial scale from molasses using high gravity technology by mutant S. cerevisiae
Abstract Very high gravity (VHG) technology was employed on industrial scale to produce ethanol from molasses (fermented) as well as by-products formation estimation. The effect of different Brix° (32, 36 and 40) air-flow rates (0.00, 0.20, 0.40, and 0.60 vvm) was studied on ethanol production. The maximum ethanol production was recorded to be 12.2% (v/v) a

29. Study of Continuous Rheological Measurements in Drilling Fluids
Abstract Drilling an oil well involves using drilling fluids that perform cleaning and cooling functions, but that most importantly maintain the fluids of the geological formation contained by hydraulic pressure. A fundamental role in predicting the hydraulic pressure of the well consists of monitoring the fluid’s rheological behavior. This paper summarize

30. Phase Equilibria in the Tl5Te3-Tl9BiTe6-Tl9TmTe6 Section of the Tl-Bi-Tm-Te Quaternary System
Phase relations in the Tl5Te3-Tl9BiTe6-Tl9TmTe6 section of the Tl-Bi-Tm-Te quaternary system were studied by differential thermal analysis, powder X-ray diffraction technique and microhardness measurements applied to equilibria alloys. Some isopleth sections and isothermal section at 760 K, as well as projections of the liquidus and solidus surfaces, were co

31. Softening Mechanisms of the AISI 410 Martensitic Stainless Steel Under Hot Torsion Simulation
This study investigated the softening mechanisms of the AISI 410 martensitic stainless steel during torsion simulation under isothermal continuous in the temperature range of 900 to 1150 °C and strain rates of 0.1 to 5.0s-1. In the first part of the curves, before the peak, the results show that the critical (εc) and peak (εp) strains are elevated for hig

32. Atmospheric Pressure Continuous Production of Solketal from the Acid-Catalyzed Reaction of Glycerol with Acetone
A continuous-flow process at atmospheric pressure was designed for the conversion of glycerol to solketal, an oxygenated fuel additive, through the acid-catalyzed reaction of glycerol with acetone. Process optimization was performed by checking the influence of different variables on the conversion and selectivity. The variables examined were: residence time

33. Spore Germination and Protonemal Development of Dolichomitriopsis diversiformis
ABSTRACT Dolichomitriopsis diversiformis is an endemic and threatened moss in eastern Asia. In vitro culture and light microscopic observation were employed to study its developmental process from spore germination to the formation of young gametophyte, as well as effects of light and temperature on its spore germination and protonemal development. Microscop

34. Slope stability analysis at highway BR-153 using numerical models
Abstract An existing cut slope on Highway RS-471/BR-153 is studied. The slope is composed of the Serra Geral Formation's material: a highly altered volcanic breccia and above it a slightly altered and very fractured rhyolite. A numerical analysis of the slope is carried out in two dimensions. Fracturing of the rhyolite necessitates the use of a constitutive

35. Effect of Cr Additions on Ferrite Recrystallization and Austenite Formation in Dual-Phase Steels Heat Treated in the Intercritical Temperature Range
An experimental investigation was conducted using laboratory-processed low carbon Mn-Mo-Nb-Ti-B dual phase steel with additions of 0.2Cr or 0.6%Cr. This study investigates the effect of Cr additions on ferrite recrystallization and austenite formation during continuous annealing in the intercritical temperature range. It was found that moderate additions of

36. Self-Organization in Ionic Liquids: From Bulk to Interfaces and Films
In this contribution we present an overview on the relation between the complex structure of ionic liquids (ILs) and its impact in the field of surface science. The results herein described result mainly from modeling and simulation work carried out at Centro de Química Estrutural, Universidade de Lisboa, complemented in some cases by experimental results o
