Rigid palm oil-based polyurethane/kenaf fibre biocomposite foams were prepared at various amounts of kenaf fibre (i.e.2.5, 5.0, 7.5, 10.0 and 12.5 pphp).Effects of kenaf fibre (KF) loadings on thermal stabilities and compressive strength were investigated.The peaks detected by Fourier transform infrared (FTIR) at 3,310 cm-1 (OH stretching), 1,533 c
This paper presents theoretical consideration of a travel route and speed profile while turning at an intersection.These two are important for vehicle movement and ride comfort.The curvature distribution of a travel route is an important physical quantity that generates a traveling track.The formulation and characteristics of a transition curve at
Abstract Objective: To describe the factors associated with dental caries among students from Santa Cruz do Sul, Rio Grande do Sul, Brazil.Methods: A cross-sectional study was conducted in a random sample of 623 students of both genders, aged 10-17 years old.Tooth decay was performed using the index of the World Health Organization (1997), DMFT (pe
Gene expression manipulation of specific metabolic pathways can be used to obtain bioaccumulation of valuable molecules and desired quality traits in plants.A single-gene approach to impact different traits would be greatly desirable auren3 in agrospace applications, where several aspects of plant physiology can be affected, influencing growth.In t
