Choose the correct word to complete these descriptions of stellar explosions. There are two types of stellar explosions which can occur in binary systems where a white dwarf steals gas from its companion a star. For a , the gas is ignited only on the surface of the white dwarf, meaning this process can occur multiple times if more gas is collected later. For a , the entire white dwarf detonates. No remnant is left behind after this, so the process cannot occur multiple times. On the other hand, a occurs only once for an isolated high-mass star. This process begins when the star builds up in its core. This element can't fuse, so it doesn't produce pressure to balance gravity. The core collapses suddenly, squeezing protons and electrons together, converting them into and . The core collapses rapidly until it rebounds, sending a spray of material outward which collides with the material still rushing inward. This 1) fuses elements heavier than iron and 2) causes a violent explosion that leaves behind a supernova remnant. Depending on the mass, the Earth- sized core will become either a city-sized or an infinitely small.

Unit 3: Why Does the Sun Shine?
The sun generates about 400 billion billion
megawatts of power and it has done so for five
billion years. Nuclear fusion – combining lighter
atoms to make heavier ones – is what makes it
possible.

How much of the human body is made up of stardust,Does atoms age and what is the age of atoms. If an atom or molecule becomes electrically charged by gaining or losing one or more electrons, it becomes an ion. If the atom gains electrons, it has a negative charge. If it loses electrons, it has a positive charge. Please read the following then answer the questions-The term blac.pdf
Please read the following then answer the questions:-
The term black hole is of very recent origin. It was coined in 1969 by the American scientist
John Wheeler as a graphic description of an idea that goes back at least two hundred years, to a
time when there were two theories about light: one, which Newton favored, was that it was
composed of particles; the other was that it was made of waves. We now know that really both
theories are correct. By the wave/particle duality of quantum mechanics, light can be regarded as
both a wave and a particle. Under the theory that light is made up of waves, it was not clear how
it would respond to gravity. But if light is composed of particles, one might expect them to be
affected by gravity in the same way that cannonballs, rockets, and planets are. At first people
thought that particles of light traveled infinitely fast, so gravity would not have been able to slow
them down, but the discovery by Roemer that light travels at a finite speed meant that gravity
might have an important effect. On this assumption, a Cambridge don, John Michell, … pointed
out that a star that was sufficiently massive and compact would have such a strong gravitational
field that light could not escape: any light emitted from the surface of the star would be dragged
back by the star’s gravitational attraction before it could get very far. Michell suggested that
there might be a large number of stars like this. Although we would not be able to see them
because the light from them would not reach us, we would still feel their gravitational attraction.
Such objects are what we now call black holes, because that is what they are: black voids in
space. In fact, it is not really consistent to treat light like cannonballs in Newton’s theory of
gravity because the speed of light is fixed…. A consistent theory of how gravity affects light did
not come along until Einstein proposed general relativity in 1915. And even then it was a long
time before the implications of the theory for massive stars were understood. To understand how
a black hole might be formed, we first need an understanding of the life cycle of a star. A star is
formed when a large amount of gas (mostly hydrogen) starts to collapse in on itself due to its
gravitational attractions. As it contracts the atoms of the gas collide with each other more and
more frequently and at greater and great speeds- the gas heats up. Eventually, the gas will be so
hot that when the hydrogen atoms collide they no longer bounce off each other, but instead
coalesce to form helium. The heat released in this reaction, which is like a controlled hydrogen
bomb explosion, is what makes the star shine. This additional heat also increases the pressure of
the gas until it is sufficient to balance the gravitational attraction, and the gas stops
contracting…. Stars will remain stable like this for a long time, with heat from the nuclear
reactions balancing the gravitational attraction. Eventually, how.

Stars
'A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardised stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes.'
on-the-origin-of-the-moon-and-the-continents.pdf
All astronomical bodies originate inside clouds of gas and dust, therefore there should be a common process that leads to
their condensation. In a galactic cloud there is always a gradient of speeds from point to point. Thanks to it, vortices originate
that rake the material of the surrounding cloud gradually forming large gaseous disks, inside which vortices of second order
develop that concentrate the matter of their orbits forming smaller and much denser disks, within which third order vortices
further concentrate the matter. The dense cores of these vortices finally condense in massive bodies: sun, planets and satellites.
The result should be a well ordered planetary system with no “debris” around and where both planets and satellites obey to
a precise rule of the distances from their central body. The solar system complies with these conditions with three main
exceptions. First, in an orbit where a large planet should be there is only a huge number of scattered asteroids. Second, Earth
and its moon with all evidence were not formed in the same vortex, which means that Moon originated somewhere else. Third,
Neptune’s satellite system has been shattered by the intrusion of a foreign body, Triton, and its largest satellites are missing.
These exceptions seem to be strictly connected to each other and all due to a unique event, that is: Triton has diverted the
largest Neptune satellite towards the Sun. This satellite impacted at high speed against the missing planet, scattering myriads
of fragments from its mantle and pushing it towards the sun, where it eventually fell. The planet had at least 4 satellites some
of which remained in their previous orbit, but two of them were dragged towards the sun and were captured by Earth. The
largest became its lonely moon while the second fell on its surface giving origin to the continents. This event happened about
3,96 billion of years ago, as it is proven by the ages of the numerous samples brought from the moon

Cinematix se vuelve mvil
Cinematix Cinema ha revisado recientemente la informacin de una serie de encuestas que
involucran varios tipos de evaluaciones de productos. Todas las encuestas se completaron en
lnea con clientes reclutados de su panel propietario. Adems de los datos reales de la encuesta y
otra informacin, el sistema de entrevistas en lnea captura el navegador que us el encuestado para
completar la encuesta. Al analizar los datos de "navegador utilizado", Sonic ha observado un
aumento lento pero constante en la cantidad de personas que completan la encuesta en
navegadores mviles, incluidas tabletas y telfonos inteligentes. Los resultados ms recientes
muestran un gran salto en este porcentaje desde hace un ao, con un promedio de casi el 30 por
ciento de las encuestas ms recientes completadas en navegadores mviles. Varios gerentes han
intentado completar algunas de estas encuestas usando sus propias tabletas y telfonos
inteligentes. Les gusta la idea de que el uso de estas plataformas aumente las opciones para el
consumidor y que estos dispositivos permitan a los consumidores realizar las encuestas en
momentos y lugares en los que antes no podan hacerlo. Sin embargo, sus experiencias al probar
las encuestas en sus dispositivos mviles han sugerido que es posible que deban cambiar la forma
en que disean los cuestionarios para adaptarse a los telfonos inteligentes y las tabletas..

Choose one of these three options A IPC using FIFO B Shar.pdf
Choose one of these three options: A. IPC using FIFO B. Shared memory C. Sockets and Client-
Server In this lab, you will be required to write two C routines which talk to each other through a
communications channel. You can Choose to either implement the code using FIFOs, a shared
memory segment or through the use of sockets. In the description below these will be referred to
generically as "the communications channel" or just "the channel". The objective is to create a
client-server environment to copy the contents of a file from the client to the server. This will mimic
a file UPLOAD process. Your client code will run as a single process on the computer. Your server
code must also be run as a separate process on the same computer. This means having two
terminal windows running. One for the server, one for the client. No fork() or exec() calls are to be
used for this lab. The filename should be supplied to the client as a command line parameter. Your
client code, once connected, should send a message to the server. The message should contain a
filename. The server should then receive the filename and prepare to receive data. The client
should open the file and copy it through the channel to the server. You must only use read() and
write() to transfer data through the socket. Each "packet" of information sent must use a structure
that contains both the number of bytes being transferred as well as the data stream. Something
akin to: struct student_record { int nbytes; char payload[1024]; }; The server code should then
accept the data buffer through the channel and writes the identified number of bytes to the local
filename. The data exchange should happen in fixed block sizes, say 1024 bytes. When the client
sends a packet to the server containing fewer than the expected packet size, your code can
assume the client has hit the end of file. You should expect the test files I will use will be of
arbitrary length. Some will be smaller, some much larger than 1024 bytes. Restrictions: When you
are retrieving data from the source file, you must use open() and read(). You are not allowed to
use fopen() as it will not read binary files properly. You are not allowed to use the sendfile()
system call or any other bulk transfer utilities. Depending on the approach you have chosen, you
are required to read()/write() or send()/recv() the data and then push it through the channel you
created. Both the server and client should close their copy of the file. The client should then send
a disconnect message to the server and exit. Your destination filename should be something like:
lab6_sourcefile_local_clone.
A) IPC using FIFO Your client code should use two FIFOs. One for client-to-server transfers and
one for server-to-client messages. You are allowed to assume that these FIFOs have static well
known names and that only one client will ever be talking to the server at a time. The client must
check for the presence of both FIFOs before it accepts user input..

2024.06.01 Introducing a competency framework for languag learning materials ...
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.

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.

Choose the correct word to complete these descriptions of st.pdf
- 1. Choose the correct word to complete these descriptions of stellar explosions. There are two types of stellar explosions which can occur in binary systems where a white dwarf steals gas from its companion a star. For a , the gas is ignited only on the surface of the white dwarf, meaning this process can occur multiple times if more gas is collected later. For a , the entire white dwarf detonates. No remnant is left behind after this, so the process cannot occur multiple times. On the other hand, a occurs only once for an isolated high-mass star. This process begins when the star builds up in its core. This element can't fuse, so it doesn't produce pressure to balance gravity. The core collapses suddenly, squeezing protons and electrons together, converting them into and . The core collapses rapidly until it rebounds, sending a spray of material outward which collides with the material still rushing inward. This 1) fuses elements heavier than iron and 2) causes a violent explosion that leaves behind a supernova remnant. Depending on the mass, the Earth- sized core will become either a city-sized or an infinitely small
