This document provides information on different types of fibres, including general fibres and high-performance fibres. It discusses the properties and uses of various high-performance fibres such as aramids, polybenzimidazole, polyphenylene sulfide, polytetrafluoroethylene, polyacrylonitrile and others. These fibres have high strength, temperature resistance and durability making them suitable for applications requiring high performance such as ballistics, aerospace engineering, protective clothing and automotive. The document also presents concepts for using high-performance fibres beyond bulletproof fabric in construction and transportation industries.

A seminar was conducted IEI[Institute of Engineers (India)], Tripura state Center, Agartala for Mechanical Engineering Department for which the chief guest was Dr. Ajay Biswas our institute beloved professor. I along with my best friend Abhishek Kumar from the same batch as well as branch presented our project research report in front of expert panelists who were either professors or doctors in several organizations and students of first year who were ordered to attain the seminar in lust of snacks and a certificate which they can show during their campus placement drive session. The project presentation was fabulous and brought praises and constructive critiques from present faculties and panelists. As momento we were provided with a beautiful tea cup and awarded with a certificate from IEI briefing that we had successfully presented our research paper. The whole time duration was very charming and boosted my self-confidence.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
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.

3. DIFFERENCE BETWEEN GENERAL FIBRES AND HIGH
PERFORMANCE & TEMPERATURE RESISTANT FIBRES:
1. GENERAL FIBRES CAN BE USED FOR HUMAN WEARING CLOTHING
BACOUSE, IT GIVES COMFORT TO HUMAN BODY. H.P.T.R FIBRES
DOSEN’T GIVING COMFERT TO BODY BUT IT PROTECTS BODY
FROM ACCIDENT OF BULLET TYPE MATERIAL.
2. THE USE OF COTTON AND OTHER FIBRES DO NOT HAVE
CAPABILITY TO USED IN INDUSRIAL APPLICATIONS.
