The processing technique employing a suspension or fluidization of small solid particles in a vertically rising stream of fluid usually gas so that fluid and solid come into intimate contact. This is a tool with many applications in the petroleum and chemical process industries. Suspensions of solid particles by vertically rising liquid streams are of lesser interest in modern processing, but have been shown to be of use, particularly in liquid contacting of ion-exchange resins. However, they come in this same classification and their use involves techniques of liquid settling, both free and hindered (sedimentation), classification, and density flotation.

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.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

2. Gravity Settling Processes
Two types of sedimentation
1. Gravity settling and 2. Centrifugal settling
Particles heavier than the suspending fluid may be removed from a gas or
liquid in a large settling box or settling tank. ( fluid velocity is low and the
particles have ample time to settle out.)
Industrial separators nearly all provide for the continuous removal of settled
solids.
The separation may be partial or very nearly complete.
A settler that removes virtually all the particles from a liquid is known as a
clarifier.
whereas a device that separates the solids into two fractions is called a
classifier.
3. GRAVITY CLASSIFIERS
Separate particles on the basis of size and the density of the fine particles
(the same as that of the larger ones.)
Working- By adjusting the upward velocity of the liquid so that it is smaller
than the terminal settling velocity of acceptably large crystals, this device
carries unwanted fine crystals back to the crystallizing zone for further
growth.
Mechanical classifiers are used in closed-circuit grinding, especially in
metallurgical operations.
Here the relatively coarse particles are called sands and the slurry of fine
particles is called slimes.
Sufficient time is provided to allow the sands to settle to the bottom of the
device; the slimes leave in the effluent liquid.
4. SORTING CLASSIFIERS
Devices that separate particles of differing densities are known as sorting
classifiers.
They use two principal separation methods—sink-and-float and differential
settling.
5. Sink-and-float methods
A sink-and-float method uses a liquid sorting medium, the density of
which is intermediate between that of the light material and that of the
heavy.
Then the heavy particles settle through the medium, and the lighter ones
float, and a separation is thus obtained.
This method is also called heavy fluid separation.
Separation - independent of the particle size.
Used to treat relatively coarse particles, greater than 10-mesh.
Medium - Halogenated hydrocarbons and CaC12 solutions and pseudo
liquid consisting of a suspension in water of fine particles of a heavy
mineral
7. Differential settling methods
Differential settling methods utilize the difference terminal velocities that
can exist between substances of different density.
disadvantage the method is that since the mixture of materials to be
separated covers a rani of particle sizes, the larger, light particles settle at
the same rate as the small, heavy ones and a mixed fraction is obtained.
But this problem can be solved.
Let of two materials A and B settling through a medium density p. Let
material A be the heavier; e.g., component A might be galena (specific
gravity 7.5) and component B quartz (specific gravity 2.65).
The terminal velocity of a particle of size Dp and of density pp settling under
gravity through a medium of density p is given .
8. Continue…
the equal- settling diameter ratio is given by,
By using this plotting of terminal velocity vs avg. particle size
Its clear that from above eq., the
sharpness of separation is
improved if the density of the medium is
increased.
It is also clear from Fig. that the mixed
fraction can be reduced or eliminated by
closer sizing of the feed.
For example, if the size range of the feed
is from Do to Dp4 in Fig.,
complete separation is possible.
9. CLARIFIERS AND THICKENERS
Gravity separation under hindered settling conditions is often used to
convert a dilute slurry of fine particles into a clarified liquid and a
concentrated suspension.
This process is carried tanks called thickeners or clarifiers.
The concentrated suspension, or sludge, may have to be filtered to produce
a drier product, but the cost of the filtration step is much lower than if the
original slurry had been filtered directly.
The clarified liquid is free or nearly free of suspended particles, and it may be
reused as process water or discharged as waste.
