Abstract - Generally,the computer systems are made up of silicon-based computer technologies. In DNA computing, it is based on the computing techniques of DNA, biochemistry and molecular biology, instead of traditional silicon-based computer technology. Initially,Adleman computed an experiment which instances the Hamiltonian path problem with DNA test tubes in 1994. Then he computed further research on computation with molecular means in theoretical computer science. DNA computing has vast parallelism and high-density storage to solve many problems. Also, DNA has explored as an excellent material and a fundamental building block for developing large scale nanostructures, constructing individual nanomechanical devices, and performing computations. The input and output information will be in the molecular form which is demonstrated by molecular-scale autonomous programmable computers. This paper deals with the review of future advancements in DNA computing and challenges for researchers in future.
International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research and review articles in the fields of Computer Science, Neural Networks, Electrical Engineering, Software Engineering, Information Technology, Mechanical Engineering, Chemical Engineering, Plastic Engineering, Food Technology, Textile Engineering, Nano Technology & science, Power Electronics, Electronics & Communication Engineering, Computational mathematics, Image processing, Civil Engineering, Structural Engineering, Environmental Engineering, VLSI Testing & Low Power VLSI Design etc.
DNA Computer can store billions of times more information then your PC hard drive and solve complex problems in a less time. We know that computer chip manufacturers are racing to make the next microprocessor that will more faster. Microprocessors made of silicon will eventually reach their limits of speed and miniaturization. Chips makers need a new material to produce faster computing speeds.
A Study on DNA based Computation and Memory DevicesEditor IJCATR
The present study delineates Deoxyribonucleic Acid (DNA) based computing and storage devices which have good future in the vast era of information technology. The traditional devices mostly used are made up of silicon. The devices are costly and have physical limitations to cause leakage of electrons and circuit to shorten. So, there is a need of materials which are capable of doing fast processing and have vast memory storage. DNA which is a bio-molecule has all these characteristics capable of providing ample storage. In classical computing devices, electronic logic gates are elements which allow storing and transforming of information. Designing of an appropriate sequence or a net of “store” and “transform” operations (in a sense of building a device or writing a program) is equivalent to preparing some computations. In DNA based computation, the situation is analogous. The main difference is the type of computing devices since in this new method of computing instead of electronic gates, DNA molecules have been deployed for the processing of dossier. Moreover, the inherent massive parallelism of DNA computing may lead to methods solving some intractable computational problems. The aim of this research study is to analyze the logical features and memory formation using DNA bio molecules in order to achieve proliferated speed, accuracy and vast storage.
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.

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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
4. I believe things like DNA computing
will eventually lead the way to a
“molecular revolution,” which
ultimately will have a very dramatic
effect on the world. – L. Adleman

13. Strands of DNA represent the seven cities. In genes, genetic
coding is represented by the letters A, T, C and G. Some sequence
of these four letters represented each city and possible flight path.
These molecules are then mixed in a test tube, with some of these
DNA strands sticking together. A chain of these strands
represents a possible answer.
Within a few seconds, all of the possible combinations of DNA
strands, which represent answers, are created in the test tube.
Adleman eliminates the wrong molecules through chemical
reactions, which leaves behind only the flight paths that connect
all seven cities.
14. Hamilton Path Problem
(also known as the travelling salesperson problem)
15. given a test tube T and a strand s, it is possible to extract all the strands in
T that contain s as a subsequence, and to separate them from those that do
not contain it.

computation. Not only
entertaining, but also the most
understandable explanation of
molecular computation I have
Ever seen
18. • High cost is time.
• Occasionally slower-Simple problems
are solved much faster on electronic
computers.
• It can take longer to sort out the
answer to a problem than it took to
solve the problem.
• Reliability- There is sometime errors
in the pairing of DNA strands
19.
20. • DNA Computing utilizes the complex
interaction of bio molecules and molecular
biology to effect computation
• Lab experiments in DNA Computing are
unreliable, inefficient, unscalable and
expensive compared to conventional
computing standards
• A critical issue in DNA Computing is to test
protocols
• So we will describe a platform EDNA, to
address this problem.
21. • Address the basic problems of reliability,
efficiency and scalability for molecular
protocols using DNA molecules.
• Allows to take advantage of digital computers
to gain realistic insights on actual test tube
performance of a protocol before they are
carried out in the lab.
• It is a research tool that makes it possible to
use the advantages of conventional computing
to bring to DNA computing comparable levels
of reliability and efficiency.
22. • The encoded piece of DNA is placed
into a piece of human DNA and is then
mixed with other DNA strands.
