1. RESISTANCE OF A RED LATOSOL TO PENETRATION: COMPARISON OF PENETROMETERS, MODEL ADJUSTMENT, AND SOIL WATER CONTENT CORRECTION
ABSTRACT Penetration resistance can be determined directly in the field or in the laboratory. However, data obtained using the two methods are not directly comparable. Considering soil moisture influences penetration resistance, penetration resistance data obtained using the two methods can be corrected based on common moisture values. To enable comparison o

2. Efficiency of electricity distribution companies
Abstract Purpose After assessing papers on efficiency, most of the studies available are focused on the analysis of efficiency measures, without providing a deep discussion of the factors that determine efficiency. This study aims to evaluate the efficiency of Brazilian electricity distribution companies based on a structural model that enables the identifi

3. Mathematical models to predict growth, fillet traits, and composition of wild traíra, Hoplias malabaricus
ABSTRACT This study aimed to determine the length-weight relationship and mathematical models to predict dressed and fillet weight and yield and fillet composition of wild traíra, Hoplias malabaricus (Bloch, 1794). A total of 80 marketable-sized fish from 292.28 to 2879.57 g and 32.06 to 61.19 cm were used. The length:weight ratio was estimated using the eq

4. Modeling of the Rainfall and R-Factor for Tocantins State, Brazil
ABSTRACT The state of Tocantins is inserted in the new Brazilian agricultural frontier and has shown enormous potential for expansion of the agricultural lands. However, there is a lack of more elaborate scientific information for better planning and guide agricultural activities, especially regarding the soil and water conservation. Tocantins has a relevant

5. Comparação de modelos estatísticos para estimativa da biomassa de árvores, e estimativa do estoque de carbono acima do solo em Cerrado
Resumo Neste trabalho foram comparados diferentes modelos estatísticos para a estimativa da biomassa individual de árvores, e estimados os estoques totais de biomassa e de carbono acima do solo, nos três compartimentos (arbóreo, herbáceo-arbustivo e serapilheira) de um cerrado sensu stricto típico no oeste da Bahia. Foi realizado o inventário floresta

6. Salicylic acid: resistance inducer to two-spotted spider mite in strawberry crop
RESUMO O morangueiro é atacado por diversas pragas que ocasionam redução na produtividade. Mecanismos que repelem ou evitam que essas pragas se estabeleçam representam uma tecnologia ambientalmente correta e sustentável, para reduzir a frequência no uso de agroquímicos. Neste contexto, objetivou-se avaliar o efeito do ácido salicílico (AS) na induç

7. Simultaneous Equations to Estimate Aboveground Biomass of Pinus caribaea var . hondurensis
ABSTRACT This study aimed to develop equations to predict the biomass of trunks, branches, needles and total individual biomass for Pinus caribaea var. hondurensis . A simultaneous equation system was also adjusted. Twenty (20) trees from the experimental area of the State University of Southwest Bahia (UESB), Vitória da Conquista, Bahia, Brazil, were meas

8. REGIONALIZATION OF MAXIMUM AND MINIMUM FLOW IN THE TELES PIRES BASIN, BRAZIL
ABSTRACT In a watershed there is space and climate variability within its catchment area, causing changes in water qualitative and quantitative characteristics. Thus, the hydrological data collected from a specific basin may be extrapolated to neighboring basins with similar physical characteristics, using techniques of hydrological regionalization. This stu

9. Adjustment of four growth models through Bayesian inference on weight and body nutrient depositions in laying quail
ABSTRACT An experiment was conducted to estimate the parameters of the Gompertz, Brody, Logistic, and Von Bertalanffy equations through Bayesian inference and evaluate the potential for growth in terms of weight and body composition of laying female quail (Coturnix coturnix japonica). The weights and body compositions of the birds were obtained weekly (1-119

10. Empirical analysis of the International Classification of Functioning, Disability and Health (ICF) using structural equation modeling
ABSTRACT Objective: To empirically test the relationships proposed by the International Classification of Functioning, Disability and Health (ICF) among its domains. Method: The cross-sectional study was completed with 226 adult patients with different health conditions who attended a Brazilian rehabilitation unit. The ICF components were measured with the f

11. Feeding behavior and productive performance of steers fed pearl millet grain-based diets containing proportions of babassu mesocarp bran
ABSTRACT The objective of this study was to evaluate the feeding behavior and feedlot productive performance of dairy-origin steers fed for 84 days ground pearl millet grain-based diets with 0, 120, 240, 360, and 480 g kg-1 of babassu mesocarp bran (BMB) and a standard diet based on ground corn. Thirty Holstein-Zebu steers with average initial body weight of

12. Evaluation of decomposition kinetics of poly (ether-ether-ketone) by thermogravimetric analysis
The non-isothermal thermogravimetric methods have been used extensively for the determination of kinetic parameters in polymers. The poly (ether ketones) are used as matrix in advanced high performance composites due its high thermal stability, excellent environmental performance and superior mechanical properties. In this work, the non-isothermal decomposit
