1. 3D Simulation and Artificial Neural Networks Application in the Diffusion Study of Champignon Mushroom/Solution Interface During the Salting
The influence of the film formed during the salting of champignon mushrooms with brine containing NaCl and KCl was modeled using the finite elements method (FEM). It was verified that the film formed on the mushroom surface had a greater influence in the static salting since the diffusion of the ions was 7.5-fold smaller in this system than in the stirred sa

2. Rotational thromboelastometry assessment of ballanced crystalloid, hydroxyethyl starch and gelatin effects on coagulation: a randomized trial
Resumo Justificativa e objetivos Os cristaloides e coloides modernos são soluções balanceadas e cada vez mais utilizadas no período perioperatório. No entanto, não há estudos que avaliem seu efeito negativo na coagulação do sangue total e o intenso debate sobre a solução que cause um efeito mínimo na coagulopatia permanece. O objetivo de nosso e

3. Decentralising scientific publishing: can the blockchain improve science communication?
We present a decentralised solution for managing scientific communication, based on distributed ledger technologies, also called blockchains. The proposed system aims to solve incentive problems displayed by traditional systems in scientific communication and publication. A minimal working model is presented, defining roles, processes, and expected results f

4. Sanitizing cinnamaldehyde solutions against Pseudomonas aeruginosa biofilms formed on stainless steel surfaces
Resumo Pseudomonas aeruginosa é um patógeno oportunista capaz de formar biofilmes de grande relevância para a microbiologia médica e para a indústria de alimentos. Os constituintes do óleo essencial (OE) têm sido pesquisados como novas alternativas para o controle do biofilme. Neste estudo, o cinamaldeído mostrou-se eficaz como OE contra células pla

5. Genetic control of aluminum tolerance in tropical maize germplasm
ABSTRACT Aluminum (Al) toxicity is the most limiting factor to maize crop productivity in acid soils. Therefore, the understanding of inheritance of Al tolerance in maize is important for the developmentof more adequate procedures for Al tolerant genotypes selection. In this sense, the objectives of this study were to determine the inheritance, and the gener

6. MEASURING THE CONDUCTIVITY OF VERY DILUTE ELECTROLYTE SOLUTIONS, DROP BY DROP
Undergraduate experiments on ionic conductivity are common practice in general chemistry and advanced physical chemistry laboratories. Often, the conductivities are measured for solutions prepared for various salts, in a range of concentrations, and the relationship between solution conductivity and concentration is interpreted in terms of the Kohlrausch law

7. Use of Mixture Design with Minimal Restrictions to Optimize an Extraction Procedure Employing Diluted Acids Assisted by Ultrasound and Microwave for Nutrient Element Determination in Vegetal Samples
In this work, it was developed an alternative analytical strategy for the preparation of vegetal samples extracted with diluted acids and assisted by ultrasound and microwave radiation for the determination of nutrients elements by fast sequential flame atomic absorption spectrometer. The conditions optimized using univariate and multivariate methodologies f

8. Potentiometric Titration and Out-Of-Equilibrium pH Response of the Biotite‑Water System
Minerals in soils contribute significantly to the capacity of soils to buffer pH disturbance. In this paper, we present the pH buffering capacity of a common soil phyllosilicate mineral, biotite. We performed equilibrium potentiometric titrations and we also monitored the pH response kinetics of the mineral-water system in order to develop an out-of-equilibr

9. Multi-model MPC with output feedback
In this work, a new formulation is presented for the model predictive control (MPC) of a process system that is represented by a finite set of models, each one corresponding to a different operating point. The general case is considered of systems with stable and integrating outputs in closed-loop with output feedback. For this purpose, the controller is bas

10. Desenvolvimento e caracterização de microesferas de fosfato de cálcio bifásico / Development and characterization of biphasic calcium phosphate microspheres
The biphasic calcium phosphate is greatly applied in the replacement of osseous tissues and as dermal fillers due to its chemical similarity with the mineral part of bone and teeth. Due to this similarity, the calcium phosphates present, among other important properties, high biocompatibility, bioactivity and/or osteoconduction. They do not induce inflammato

11. Modulação do transporte de prótons em osteoclastos: efeitos da acidose e do fluxo de fluido extracelular. / Modulation of proton transport in osteoclasts. Effects of acidosis and extracellular fluid flow.
Metabolic acidosis can cause a loss of bone mineral and the mechanic stimulation can cause adaptative bone remodeling. The bone resorption characteristic of these bone changes aforementioned depends on the extracellular acidification by osteoclastmediated proton secretion. The H+ secretion by vacuolar H+-ATPase together with Clsecretion through a Cl-/H+ exch

12. Tolerância ao alumínio em plântulas de milho / Aluminum tolerance in maize plants
A seleção para tolerância ao alumínio é complicada pela desuniformidade natural dos solos e pela dificuldade de avaliar danos na raiz. Assim sendo, é importante desenvolver métodos eficientes de caracterização da tolerância ao alumínio em condições controladas de ambiente. O presente trabalho teve por objetivo adequar o método de solução mín
