A new approach to implement a customized anatomic insole in orthopaedic footwear of lower limb orthosis
This paper concerns the development of a new approach for orthopaedic
footwear to apply in KAFO orthosis (acronym for Knee Ankle Foot Orthosis). This
procedure starts with full characterization of the problem with the purpose to
characterize a plantar of a patient’s foot with polio. A 3D Scanner was used to collect
their feet's data to produce an anatomic insole. After this step, the patient performs a
study of his gait using a static and dynamic study with the aim of characterizing the
parameters to improve quality in the footwear. The insole was produced using a 3D
printing technology. It was essential to optimize manufacturing processes and it was
developed a footwear prototype with innovative characteristics, which is 25% lighter,
allowing the user to consume less energy in daily routines.This work is supported by FEDER funding on the COMPETE program and by national funds through FCT-Foundation for Science and Technology within the scope of the project POCI-01-0145-FEDER- 007136 and UID/CTM/00264.info:eu-repo/semantics/publishedVersio
Phase behavior of olive and soybean oils in compressed propane and n-butane
The aim of this work is to report the experimental data and thermodynamic modeling of phase equilibrium of binary systems containing soybean and olive oils with propane and n-butane. Phase equilibrium experiments were carried out using the static synthetic method in a high-pressure variable-volume view cell in the temperature range from 30 to 70ºC and varying the solvent overall composition from 5 to 98 wt%. Vapor-liquid, liquid-liquid and vapor-liquid-liquid phase transitions were observed at relatively low pressures. The Peng-Robinson and the SAFT equations of state without any binary interaction parameters were employed in an attempt at representing the phase behavior of the systems. Results show the satisfactory performance of SAFT-EoS in predicting qualitatively all phase transitions reported in this work
