1. Extraction and Characterization of Pequi Seed Oil for Biodiesel Production: A Green Management of Waste to Biofuel Using Ethanol and Heterogeneous Catalysis
This work reports the characterization of a vegetable oil extracted from pequi seeds, an agroindustrial residue, and its biodiesel production using ethanol and heterogeneous catalysis. The pequi seeds showed 40.73 wt.% of extractive content, which represents a large amount of the biomass composition. The crude oil extracted from the pequi seeds with ethanol

2. Least limiting water range in Oxisol under two conservation tillage systems in sugarcane farming
ABSTRACT The Least Limiting Water Range (LLWR) is an indicator of soil physical quality, contributing in information to propose soil management systems in agricultural farming process. This work aimed to assess the usage of LLWR and critical soil bulk density for physical-water quality evaluations, as well as its effect on sugarcane farming under no-tillage

3. Root morphology and kinetics of Zn absorption by roots of common bean influenced by Zn status of the root environment
ABSTRACT Understanding the kinetics of Zn absorption by roots and its effect on morphology of this organ is relevant for improving crop management, but still poorly studied for common beans. Therefore, an experiment was conducted in a hydroponic system with five initial concentrations of Zn (CZnI): 0.0; 1.0; 4.0; 16.0 and 48.0 µmol L-1. The experiment was i

4. Fruit quality and occurrence of mildew in Niagara Rosada grown under plastic cover and defoliation rates
ABSTRACT The purpose of this study was to evaluate the agronomic behavior of the Niagara Rosada variety cultivated under plastic cover, using defoliation intensities, and its influence on the Plasmopara viticola. The experiment was conducted in Francisco Beltrão, PR, Brazil, in a vineyard of Niagara Rosada variety in a trellised system during the 2016/2017

6. O Acolhimento como Postura na Percepção de Psicólogos Hospitalares
Resumo Atualmente, é possível encontrar múltiplas vertentes no significado atribuído à prática do Acolhimento, em especial aquelas descritas nas diretrizes da Política Nacional de Humanização (PNH). No contexto das práticas psicológicas, no entanto, os significados e as características do Acolhimento não são suficientemente explorados pela lite

7. Soil carbon accumulation in cotton production systems in the Brazilian Cerrado
ABSTRACT. Sustainable production systems, such as the no-tillage system (NTS), have a tendency to increase organic carbon in the soil. However, in Brazilian cotton production, the conventional tillage system (CTS) is predominant, and long-term studies on cotton crop under the NTS are scarce. The present study aimed to evaluate the effect of soil management a

10. Soil respiration dynamics in forage-based and cereal-based cropping systems in central Italy
ABSTRACT: Studies that have investigated soil carbon dynamics under Mediterranean conditions are scarce and fragmented and contrasting results have often been reported. This study aimed to fill some gaps in our knowledge by: (i) determining annual dynamics of total (RS) and heterotrophic (RH) soil respiration; (ii) estimating annual cumulative RS and RH; and

12. Soil chemical attributes and energetic potential of agricultural residual biomasses provided by 23-year soil management
ABSTRACT Residual biomass from grains has potential as an energetic source. Biomass composition determines this potential and is related to plant nutrition, which may vary according to soil fertility. The aim of this 23-year field study was to evaluate changes in chemical attributes of a Brazilian Oxisol and in the energetic potential of oat (Avena sativa L.
