THE SHADOW-SUIT EXOSKELETON
D-MECHD (PROTOTYPE OF
DEFENCE MECHANIC AL DRUG
DELIVERY SYSTEM)
NATURAL CONCRETE RETARDER
FROM SUGARCANE BAGASSE
This project proposes a standalone suit
codenamed the Shadow-Suit (SS) to function
as the control module concept to be applied in
any non-anthropomorphic exoskeleton design.
The SS enables the motion detection to be
performed in a separate entity, thus allowing a
wider range of wearer sizes. Result indicated
despite the difference in wearer’s anthropometry,
the exoskeleton is still capable of performing the
required task within 72% comfort level with an
approximation of 1.2 seconds lag minimization.
The very slow progress in the efficacy of the
treatment of severe diseases has suggested a
growing need for a multidisciplinary approach to
the delivery of therapeutics to targets in tissues.
From this, new ideas on controlling the efficacy
of drugs were generated. These new strategies,
often called Drug Delivery Systems (DDSs), which
are based on interdisciplinary approaches that
combine Biomedical Science and Engineering
Field. The technology involved in a drug delivery
system can be classified into three fields; releasing
technology, targeting technology, and controlled
membrane transport. The goal of controlled drug
delivery system is to directly deliver drugs to
tumor/cancer sites. Controlled drug delivery with
good targeting, precise amount and exact speed
of release are critical for drug effects. This requires
considerations of not only side effects of the drug,
but also the stability of the drug during the delivery
process. An ideal of nano capsule robot could
be develope to maneuver itself to investigate the
intestine and release the drug agents into the body
where the tumors cell are located.
In construction activity, concreting work is one of
the main tasks in process flow. Sometime, concrete
need to be mixed with chemical retarder to prolong
the setting time. According to Building Specification
2005 by the Public Work Department of Malaysia
and literature, concrete can set or hardened in 2
hours. Therefore, for the usage of supply chain and
limited pouring time especially in the area that far
from concrete plant, chemical retarder has been
put to retard the hardened process. Concrete
retarder is an admixture used to prolong concrete
setting time for the used of far concrete delivery
and more time needed in concreting work. In
this research, the retarder that being promoted
is sugarcane bagasse. The main composition of
sugarcane is the Sucrose (C12H22O11). This
content similar in chemical content for concrete
retarder. By using Vicat apparatus for a penetration
test, it can compare the time taken between normal
concrete mix and with sugarcane bagasse in term
of setting time. Few samples were prepared from
the sugarcane bagasse with 1%, 3% and 5% by
0.53 water/cement ratio of concrete mix. This
product will promote the sustainable waste material
as non chemical adding material in concrete as a
retarder. Several tests have been conducted and
the result showed that the concrete samples were
hardened between 4-5 hours without decreasing
the strength. The product that will be promoted is
sugarcane bagasse as a natural waste to be used
as a part of construction material.
