NEED FOR CYBER LAWS
1. Cyberspace is an
intangible
dimension that is impossible togovern and regulate usingconventional law.
2. Cyberspace has complete
disrespect for jurisdictionalboundaries

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.

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.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

12. Learning Competencies/Objectives:
A.Describe how electromagnetic (EM) Wave is
produced and propagated.
B.Compare the relative wavelengths, frequencies
and energies of the different regions of he
electromagnetic spectrum.
C.Cite examples of practical applications of the
different regions of EM waves.
15. Electromagnetic waves are created
by the vibration of an electric charge.
This vibration creates a wave which
has both an electric and a magnetic
component.
18. Unlike sound waves, which
need "something" to travel
through (for example, water or
air), electromagnetic waves are
able to travel through
"emptiness" or a vacuum.
19. An electromagnetic wave transports its energy
through a vacuum at a speed of 3.00 x 108 m/s (a
speed value commonly represented by the
symbol c). The propagation of an electromagnetic
wave through a material medium occurs at a net
speed which is less than 3.00 x 108 m/s.

when the changing magnetic

causes another changing
magnetic field, and so on.

26. EM spectrum is a
continuum of EM waves
arranged according to
frequency and
wavelength.
27. It shows a gradual progression
from the waves of lowest
frequency to the waves of highest
frequency or vice versa.
The different EM waves do not
have exact dividing region.

Newton set up a prism near his window, and
projected a beautiful spectrum 22 feet onto
the far wall. Further, to prove that the prism
was not coloring the light, he refracted the
light back together.

Frederick William
Herschel
(1738 - 1822)
In 1800 he performed a famous experiment where
he tried to measure the temperature of different
colours of the spectrum by placing a thermometer
on each colour. He found to his amazement that the
hottest part of the spectrum was in a place where
there was no colour at all. It was a spot beyond the
red end of the spectrum. For the first time it was
possible to talk about invisible light. This hot light
became known as Infra Red (below the red) because
it was shown to have longer wavelength than visible
light. [http://www.krysstal.com/spectrum.html]

_classroom/classroom_activities/ritter_bio.
html
In chemistry at that time there was a rumour that blue light
was more efficient at initiating chemical change than red
light. Ritter tried to measure the speed at which silver
chloride broke down with different colours. He proved that
blue light was indeed more efficient that red light. He was
amazed, however, that the most vigorous reactions took
place in the region beyond the violet where nothing could
be seen.
This new radiation was originally called Chemical Rays but is
now called Ultra Violet (beyond the violet). Ultra Violet
differs from visible light only in its wavelength which is
shorter. [http://www.krysstal.com/spectrum.html]

ich_Hertz
He set up electric circuits that produced
oscillations and managed to produce
electromagnetic radiation with a wavelength
of 66cm (over a million times longer than
light). This radiation could be picked up by
other circuits set up quite a distance away. The
new radiation was first called Hertzian Waves;
this became Radiotelegraphic Waves after
Marconi. We now call them Radio Waves.

Perry Spencer (1894 - 1970) invented the
microwave oven
In 1945, Percy Spencer was experimenting with a new
vacuum tube called a magnetron while doing research for
the Raytheon Corporation. He was intrigued when the candy
bar in his pocket began to melt, so he tried another
experiment with popcorn. When it began to pop, Spencer
immediately saw the potential in this revolutionary process.
In 1947, Raytheon built the first microwave oven, the
Radarange.
[http://science.howstuffworks.com/innovation/scientific-experiments/9-things-
invented-or-discovered-by-accident2.htm]
The scientists discovered the cosmic
microwave background radiation. This
radiation, which fills the entire Universe, is
believed to be a clue to it's beginning,
something known as the Big Bang.

Wilhelm Conrad Roentgen
(1845 - 1923)
On the night of 5 November 1895, he noticed a glow coming
from a chemical called barium platinocyanide. This chemical
glowed whenever the tube was on, even if he put cardboard
between it and the tube.
Roentgen went on to show that the glow was caused by a
highly penetrating but invisible radiation given off by the
tube. It passed through paper, thin sheets of metal, flesh. It
could ionise gases and had wave properties like light but
only much shorter wavelengths.
The new radiation was called X-Rays because of their
mysterious properties. Roentgen refused to patent the
discovery or make any financial gain out of it but he was
awarded the first ever Nobel Prize for Physics.

Villard discovered gamma radiation in 1900, while studying
radiation emitted from radium. Villard knew that his
described radiation was more powerful than previously
described types of rays from radium, which included beta
rays, first noted as "radioactivity" by Henri Becquerel in
1896, and alpha rays, discovered as a less penetrating form
of radiation by Rutherford, in 1899. However, Villard did not
consider naming them as a different fundamental type.
Villard's radiation was recognized as being of a type
fundamentally different from previously named rays, by
Ernest Rutherford, who in 1903 named Villard's rays
"gamma rays" by analogy with the beta and alpha rays that
Rutherford had differentiated in 1899.
