The document discusses polymers and several activities conducted with polymers. It then describes a design project to create a humidity sensor using a polymer film. It also outlines a project to develop self-healing electrical cables using a self-healing polymer. The polymer would be synthesized in the cable's outer layer to prevent cutting and maintain the cable's function for longer by protecting against electricity leakage. Testing is still needed to confirm the durability of this application, which could also be extended to other electrical equipment. In conclusion, polymers have various properties and uses that can help solve problems when applied in daily life.

Thermal conductivity Characterization of Bamboo fiber reinforced in Epoxy ResinIOSR Journals
Over a past few decades composites, plastics, ceramics have been the dominant engineering material. The areas of applications of composites materials have grown rapidly and have even found new markets. The current challenge is to make the durable in tough conditions to replace other materials and also to make them cost effective .This has resulted in development of many new techniques currently being used in the industry. While the use of composites it is clear choice in many applications but the selection of material will depend on the factor such as working life, lifetime requirement, complexity of product shape produced, saving the term cost. The availability of natural fiber is abundances and also they are very inexpensive when compared to other advanced manmade fibers. The primary advantage of natural fibers are low density, low cost, biodegradability, acceptable specific properties, less wear during extracting as well as manufacturing composites and wide varieties of natural fibers are locally available. The main focus of this investigation is to determine the thermal conductivity of bamboo fiber reinforced in epoxy resin composites. The test samples were prepared as per ASTM standards using simple hand-layup technique at different fiber weight fractions (10%, 20%30%, 40%50%, 60%). Thermal conductivity (K) of the composites material were determined experimentally and is validated by the results obtained by rule of mixture, E-S model and also by finite element modeling

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

8. Introduction
• Electrical cables are used to connect two or more
devices, enabling the transfer of electrical signals
or power from one device to the other.
• Cables are used for a wide range of purposes, and
each must be tailored for that purpose.
• Cables are used extensively in electronic devices
for power and signal circuits.
9. Aim of the project
• Using self-healing polymer in manufacturing
of the electric cables to protect them from
being cut and damaged.
• By this we can decrease the electrical wastes
which are harmful for the environment.
• Also applying this idea will make these cables
more cost effective because it will last longer.
10. Hypothesis
•Using the self-healing polymer which is
composed of poly(urea-urethane) in the
coatings of electrical cables will help prolonging
the functional life span of these cables and also
reduce the electrical wastes.
11. Materials and method.
The self-healing polymer is synthesized in the
outer layer of the cable because it is the layer
that subjected to get damaged.
12. Results
•The self-healing polymer is very effective in
coating the electrical cables.
•It prevents the cutting of the wire and this
maintain the function of the cable for longer.
•It also protects against the leakage of electricity
through the uncovered wire.
13. Recommendations
• Further testing is needed to know the
durability of this product.
• This application could be extended for use in
different electrical equipments and
conductors.

Editor's Notes
Permanently cross-linked poly(urea-urethane) elastomeric network was demonstrated to completely mend itself after being cut in two by a razor blade. It is the metathesis reaction of aromatic disulphides, which naturally exchange at room temperature, that causes regeneration.
