Preparation and characterisation of thermoplastic starches from cassava starch, cassava root and cassava bagasse
- 2005
Summary: Thermoplastic starches (TPS) based on cassava starch have been produced
by extrusion at 120 °C, using glycerol as plasticizer. Three forms of cassava
starch were employed, viz: cassava root (CR), cassava bagasse (CB) and purified
cassava starch (PCS). The main differences between these are the presence of
sugars and a few fibres in CR and high fibre concentration in CB. Conditions of
proc...
Finite element modelling for free vibration response of cracked stiffened FGM plates
Tập 58 Số 1 - 2020
This paper presents the new numerical results of vibration response analysis of
cracked FGM plate based on phase-field theory and finite element method. Effects
of geometrical and material properties on the vibration behaviors of the plate
are investigated in this work. The computed results show that the crack and
stiffener have a strong influence on both the vibration responses and vibration
mode...

EFFECT OF NANOSILICA FROM RICE HUSK ON THE GROWTH ENHANCEMENT OF CHILI PLANT (Capsicum frutescens L.)
Tập 54 Số 5 - Trang 607 - 2016
Nanomaterials hold great promise of improved plant disease resistance,
controlled release of agro-chemicals, enhanced plant growth, etc. In this study,
the effect of nanosilica (10 – 30 nm) prepared from rice husk on the growth
promotion of chili plant in green house was carried out. The experiment of
nanosilica treatment by foliar spraying was arranged in a factorial design with
3 replications at...

Effect of the carbonization and activation processes on the adsorption capacity of rice husk activated carbon
Tập 55 Số 4 - 2017
In this study, rice husk was used as a precursor to prepare activated carbon
using steam as a physical activation agent. Steam for activation can be used to
activate almost all raw materials. A variety of methods have been developed but
all of these share the same basic principle of initial carbonization followed by
an activation step with steam. The study also investigates the effects of
preparat...

THE EFFECTS OF SILVER NANOPARTICLES ON GROWTH OF Chrysanthemum morifolium Ramat. cv. "JIMBA" IN DIFFERENT CULTURAL SYSTEMS
Tập 55 Số 4 - 2017
Silver nanoparticles (SNPs) are one of metallic nanoparticles widely applied in
many fields. Research of SNPs application in plant tissue culture has been
gaining attention in recent years. Moreover, novel plant tissue culture systems
have been researched and developed for improving SNPs uptake capability in
medium. In this study, we investigated effects of SNPs on Chrysanthemum
morifolium ramat. ...

A novel design of the Roots blower
Tập 57 Số 2 - 2019
This paper reports a novel curve developed from non - circular gearing theory,
which can be applied in rotor profile design of the two - lobe Roots blower. The
formulas for calculating the volumetric efficiency and specific flow rate of the
blower have also been established. To evaluate this type of the Roots blower,
the volumetric efficiency and specific flow rate are being compared with those
pa...

Membrane distillation for seawater desalination applications in Vietnam: potential and challenges
Tập 55 Số 6 - 2017
Desalination of seawater using membrane distillation (MD) can be a practical
approach to mitigating the fresh water scarcity in Vietnam. This paper provides
a comprehensive review of the seawater MD desalination process. The fundamentals
of the MD process including configurations, membrane modules, membrane
properties, and heat and mass transfer mechanisms together with approaches to
enhancing hea...
