Development and Experimental Investigation of Pigeon Pea Stalk Particle Reinforced Epoxy Composites and their Hybrid Composites for Lightweight Structural Applications [PDF]

open access: yesMaterials Research, 2022
The pigeon pea (PP) stalk is a sustainable lignocellulosic material left by the farmers after harvesting its pulses. The use of agricultural residue in the development of polymer composites is a step towards sustainability.

Three-Point Boundary Value Problems for the Langevin Equation with the Hilfer Fractional Derivative

open access: yesAdvances in Mathematical Physics, 2020
We discuss the existence and uniqueness of solutions for the Langevin fractional differential equation and its inclusion counterpart involving the Hilfer fractional derivatives, supplemented with three-point boundary conditions by means of standard tools

Towards the microfoundations of finance and growth [PDF]

open access: yes, 2007
We take a critical view of the standard approach to finance and growth. The mapping between the theory and empirics is shown to be poorly understood, and this is traced to deficiencies in our understanding of the microeconomics at play.

Freeze-thaw treatment effects on the dynamic mechanical properties of articular cartilage. [PDF]

open access: yes, 2010
BACKGROUND: As a relatively non-regenerative tissue, articular cartilage has been targeted for cryopreservation as a method of mitigating a lack of donor tissue availability for transplant surgeries.

Bio-Composites Reinforced with Natural Fibers: Comparative Analysis of Thermal, Static and Dynamic-Mechanical Properties

open access: yes, 2020
In the present study, flax, jute and glass woven fabric samples were developed as reinforcement for composites with bio-epoxy resin. Flax fabrics were developed with plain weave, twill weave (different areal densities) and unidirectional (UD) structure ...

Study of selected thermoplastics using dynamic mechanical analysis

open access: yesMATEC Web of Conferences, 2018
The aim of given paper is to study selected polymers using dynamic mechanical analysis method (DMA). DMA is one of the most useful techniques for the study of the viscoelastic behaviour of thermoplastic polymers. In relation to DMA, an oscillatory stress
