1. Broccoli in succession to pearl millet: nutrient cycling, production and soil chemical attributes
ABSTRACT For its production, broccoli requires large quantities of nutrients in relatively short periods. As a conservation technique, the no-tillage planting of broccoli over the pearl millet straw in succession may interfere with the dynamics of nutrient release, inflorescence production and the chemical attributes of the soil. The objectives of this work

2. PREPARATION AND SIMULATION OF THE ON-LINE SiO2/S COATING FOR COKING INHIBITION IN THE INDUSTRIAL CRACKING FURNACE
Abstract Coke formation inside radiant coils is one of the main problems during thermal cracking of hydrocarbons. The on-line preparation of the coating for coking inhibition is a promising technology because it provides more flexibility to the operators on site. The SiO2/S coating was prepared on the inner surface of coils in an 8-year-served GK-VI industri

4. Analysis of the long-term effects of groundwater extraction on the water balance in part of the Urucuia Aquifer System in Bahia - Brazil
Resumo Em regiões agrícolas onde há insuficiência de chuva para o cultivo, entender a dinâmica das águas, superficiais e subterrâneas, é fundamental para avaliar o impacto do crescente bombeio de poços sobre o balanço hídrico. O Oeste do estado da Bahia-Brasil, maior área de agronegócio do estado, experimenta uma progressiva ocupação a partir

5. Morphometry and longitudinal profile of the river cobras sub-basin in planning the location of underground dams
RESUMO Um estudo na sub-bacia hidrográfica do rio das Cobras foi realizado com o objetivo de avaliar as características morfométricas e o perfil longitudinal da bacia hidrográfica, como ferramenta de planejamento na locação de barragens subterrâneas. Os parâmetros morfométricos - coeficiente de compacidade, fator forma, densidade de drenagem e índi

6. Compatibility of GROMOS-Derived Atomic Parameters for Lipopolysaccharide Membranes with the SPC/E Water Model and Alternative Long-Range Electrostatic Treatments Using Single Nonbonded Cutoff and Atom-Based Charge Schemes
Recent developments of GROMACS v.2016 ceased to support methodological approaches used in the development and validation of the GROMOS force field. We investigated the performance of a previously developed extension of the GROMOS force field for lipopolysaccharides to reproduce the structural dynamics of bacterial outer membrane (OM) using a single cutoff fo

7. Effect of Organic Matter on the Behavior and Control Effectiveness of Herbicides in Soil
RESUMO: Com o uso extensivo de herbicidas em áreas agrícolas, os riscos ambientais de contaminação de águas subterrâneas e superficiais por esses produtos têm se tornado preocupação mundial. Práticas de aplicação ou manutenção de resíduos orgânicos no solo que começaram a ser empregadas na agricultura para a nutrição dos solos têm demonst

8. Losartan improves alveolar bone dynamics in normotensive rats but not in hypertensive rats
Abstract Hypertension is one of the main causes of premature death in the world; also, it is associated with several bone alterations. Preclinical studies have demonstrated delayed alveolar bone healing in hypertensive rats. However, losartan has been favorable for consolidation of bone grafts and reduction in active periodontitis. Therefore, losartan is sug

9. Investigation of the effect of nozzle design on rheological bioprinting properties using computational fluid dynamics
ABSTRACT Bioprinting is the utilization of techniques derived from three-dimensional printing to generate complex biological structures which may replace natural tissues or organs. It employs high spatial resolution deposition of different cell types, growth factors and biomaterials. Those together form bioinks, which are the bioprinting inputs, analogously

10. SENSITIVITY OF EVAPOTRANSPIRATION ESTIMATED BY ORBITAL IMAGES UNDER INFLUENCE OF SURFACE TEMPERATURE
ABSTRACT Surface temperature (Ts) is a determining factor to obtain energy balance parameters, being relevant to understand the influence of this variable on the estimation of evapotranspiration. Thus, the objective of this study was to simulate errors in Ts estimation to verify the consequences of actual evapotranspiration (ETa) estimated by the SAFER (Simp

11. Dynamics of Clomazone Formulations Under Different Applications Conditions
RESUMO: A manutenção de palha sobre a superfície do solo em áreas de produção de cana-de-açúcar pode influenciar a ocorrência de plantas daninhas e a dinâmica de herbicidas. Após a aplicação, perdas consideráveis da molécula clomazone podem ocorrer, principalmente devido às suas características físico-químicas. Por esse motivo, novas formu
