1. Radiation Balance and Partitioning of Latent and Sensible Heat Fluxes Over a Lime Orchard in Eastern Amazon
Abstract We investigate the balance of radiation and energy over a lime orchard in Eastern Amazon and how it relates to environmental conditions. We found that lime trees aged between 6 and 7 years old reflect 11.0% to 14.5% of incoming shortwave radiation, and the latent heat flux corresponds to 57.6% and 66.6% of the daily net radiation in the dry season (

2. FGF23 levels as a marker of physical performance and falls in community-dwelling very old individuals
ABSTRACT Objective: The fibroblast growth factor 23 (FGF23) has been related to biological aging, but data in elderly individuals are scant. We determined the profile of serum FGF23 levels in a population of very-old individuals and studied their correlations with parameters of bone metabolism and health markers, as functional performance. Materials and me

4. ENERGY STUDY OF A GREENHOUSE AND OPTIMISATION OF THE CHOICE OF SHAPE AND COVERING MATERIAL: BASED ON AN IMPROVED STATIC MODEL
ABSTRACT This paper presents a new approach to properly estimate energy consumption inside a greenhouse. In this study, we have adopted improved classical modelling to evaluate the energy balance of a greenhouse with a higher precision. While the traditional classical model focuses mainly on the cooling and heating (and denies the deep influence of lighting

6. DESIGN AND IMPLEMENTATION OF FLC APPLIED TO A SMART GREENHOUSE
ABSTRACT Greenhouse cultivation needs an accurate modelling and an optimised control system to ensure an adequate microclimatic condition for plants. It represents a complex task due to the high number of input factors. For this reason, an improved intermediate modelling was established under the platform of the MATLAB/Simulink environment to simulate the en

7. Higher increase degree of FGF21 post long-term interdisciplinary weight loss therapy preserves the free fat mass and rest metabolic rate in adolescents with obesity
ABSTRACT Objective Fibroblast growth factor 21 (FGF21) is among the activators that can stimulate thermogenesis in the white adipose tissue and brown adipose tissue. People with obesity have elevated blood levels of FGF21, but also develop resistance to its action, impairing its beneficial role. Inversely, clinical treatments to weight loss has been pointe

8. 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

11. Evapotranspiração do sorgo a partir do balanço de energia por METRIC e STSEB
RESUMO A estimativa da evapotranspiração real da superfície (ET) contribui para quantificar as necessidades hídricas dos cultivos. Uma alternativa ao uso do lisímetro para uma estimativa precisa das necessidades hídricas, e que provou ser de grande valor nos últimos anos, é o uso do sensoriamento remoto combinado com modelos baseados no balanço de e

12. TECHNIQUES TO MINIMIZE THE EFFECTS OF ACUTE HEAT STRESS OR CHRONIC IN BROILERS
ABSTRACT High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat conditioning were evaluated. The objective of this study was to evaluate the possible interactions and effects of dietary electr
