1. Estimating leaf area of basil cultivars through linear dimensions of leaves
ABSTRACT Ocimum basilicum L. (basil) is an annual herb belonging to the Lamiaceae family that has economic importance for many regions around the world. Thus, ecophysiological studies are needed to assess this species growth and dispersal. This work aimed to obtain equations from regression models that meaningfully estimate the leaf area of basil cultivars u

2. Optimization of banana bar formulation to provide a nourishing snack for toddlers using response surface methodology
Abstract The development of banana-based snack bars that fulfill the nutritional requirement for toddlers is required. In this study, we analyzed the effects of different concentrations of banana puree, banana flour and potato starch on the characteristics of inulin, dietary fiber, protein, and potassium as well as the hardness of banana bars using response

3. ESTIMATION OF WOOD TOUGHNESS IN BRAZILIAN TROPICAL TREE SPECIES
ABSTRACT Wood has been used for several purposes such as in civil and rural construction. Knowing wood mechanical behavior under short-term loading is essential for safer structural designs. However, wood toughness is a mechanical property little investigated for this purpose. Thus, this study aimed to evaluate, using exponential and polynomial regression mo

4. Computing Cartel Overcharges: when theory meets practice
Resumo O sucesso na aplicação da lei de defesa da concorrência no que diz respeito à punição de cartéis depende de procedimentos sólidos de investigação e punição eficaz. No entanto, a legislação existente apenas fornece direção para o cálculo das multas de cartel com base na receita de vendas, ainda que tais multas não possam ser inferiore

5. Use of water-treated black tea waste instead of wheat bran in laying hen diets
ABSTRACT We assessed the effects of different amounts of water-treated black tea waste (BTW) in the diets of laying hens on performance, egg quality, yolk peroxidation, and blood parameters in this study. The experiment lasted for 12 weeks, during which a total of 108 Lohman layers, of 24 weeks old, were randomly allocated to one of six dietary treatments (1

6. Effects of two sources of Mexican oregano oil on performance, blood profile, carcass variables, and meat of broilers
ABSTRACT The current study was conducted to investigate the effects of Mexican oregano essential oil (MOO) extracts from Lippia berlandieri Schauer (LBS) and Poliomintha longiflora Gray (PLG) on performance, blood profiles, carcass variables, and meat composition of broilers at slaugther. A total of 360 one-day-old Ross broilers were randomly distributed int

7. Leaf Area Estimate of Erythroxylum simonis Plowman by Linear Dimensions
ABSTRACT This research aimed to determine an equation to estimate the leaf area of Erythroxylum simonis using the length and width of leaf blades. Two hundred leaf blades of this species were collected in Mata do Pau-Ferro, a State Park located in Areia, PB, Brazil. Regression analyses were used to determine the estimation equations. The linear, linear with

8. Feedlot performance, feeding behavior and rumen morphometrics of Nellore cattle submitted to different feeding frequencies
ABSTRACT: Owing to the lack of information in the literature about the ideal feeding frequency adopted by feedlot systems, this study was designed to evaluate the effect of different feeding frequencies on performance, carcass traits, feeding behavior and rumen morphometrics of Nellore cattle. Forty-eight yearling bulls were housed in individual pens with an

9. Models for leaf area estimation in dwarf pigeon pea by leaf dimensions
ABSTRACT This study aims to determine the most suitable model to estimate the leaf area of dwarf pigeon pea in function of the leaf central leaflet dimension. Six samplings of 200 leaves were performed in the first experiment, at 36, 42, 50, 56, 64, and 72 days after emergence (DAE). In the second experiment, seven samplings of 200 leaves were performed at 2

10. Free Damped Vibration of Rotating Truncated Conical Sandwich Shells Using an Improved High-Order Theory
Abstract In the present paper, an improved high-order theory is employed to study the free vibration of rotating truncated sandwich conical shells with laminated face sheets and a soft core. The formulation is based on a three-layer sandwich model. First-order shear deformation theory (FSDT) is used for face sheets and quadratic and cubic functions are assum

11. Influence of nails size and layout to obtain the reduction coefficient of moment of inertia for timber beams with composite cross section
ABSTRACT A significant portion of rural building’s roof is supported by timber trusses. Increasing distance between the trusses can be achieved by using composite cross sections ("T" and "I") for beams. With this, it is possible to reduce the number of columns and trusses, bringing significant savings in material and the desired cost reduction, mainly usin

12. A Doubly Curved Axisymmetric Finite Element for Subsea Sandwich Domes
Abstract The paper focuses on the analysis of sandwich domes using a newly developed doubly curved axisymmetric sandwich finite element. The simple equivalent single layer finite element employs a cubic polynomial approximation for transverse displacement and meridional displacement. The present element accounts for the transverse shear strains of the facing
