Size reduction is a process of reducing large solid unit masses, coarse particles or fine particles.
Size reduction may be achieved by two methods:
1] Precipitation
2] Mechanical process

Particle Size Analysis for Homogenization Process Development HORIBA Particle
Emulsions and suspensions are commonly used in pharmaceutical, chemical and consumer products. The pharmaceutical industry, in particular, uses emulsions and suspensions to increase drug efficacy by controlling their particle size and size distribution. Among various available preparation methods, high-pressure homogenization is one of the widely employed processes in the field. This webinar discusses ways to develop a robust homogenization process for making pharmaceutical emulsions by evaluating droplet size distribution.

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.

3. INTRODUCTION
Colloid mill is a machine that is used to
reduce the particle size of a solid in
suspension in a liquid ,or to reduce the
droplet size in emulsions.
When a liquid is suspended in another
liquid, meaning they are immiscible, this
machine is used to alternatively to
reduce the size of this droplet.
A high level of hydraulic shear stress is
applied on the fluid which results in
disrupting and breaking down the
structure.
4. PRINCIPLE
Works on the principle of ROTOR AND
STATOR
Size reduction is affected due to SHEARING
Rotor become high speed
High level of hydraulic shear applied
Shear rate leads to smaller droplets
Particle size done by modifying the gap
between Rotor and Stator
Drain pipe removes the final product
[1,2,4]
5. PARTS
To feed the material hopper is used which
are attached to the rotor and Stator
assembly.
Rotor and Stator which are made of
stainless steel may be rough or finish
surface is used for Shearing the
mixture.
Motor assembly to rotate.
A discharge point for outlets
the mixture and a auto circular
tube.
[1,2]
6. MECHANISM
The material is placed into the mill
though the inlet hopper.
It is then passed through the
narrow gap between the rotor
having and stator and thus
reduced the fine particle size. By
the help of pulverization.
Then it will come to the auto
circular tube ,until we allow it to
came out from the discharge port
The rotor speed is 3000 to
20000rpm and can
produce particle size of 1𝜇
[1,2,3]
7. APPLICATION
Used for comminution of solids
Used for formulation of Colloidal
dispersions, Suspensions, Emulsions,
Ointment
Increased the stability of Suspension,
Emulsion
Used to grinding, dispersing,
homogenizing the ointment, gels and
high viscus fluid
[1,3,4]
8. ADVANTAGE
Homogenization intensity and duration
The viscosity of the continuous phase.
The shear force within the gap between the spinning rotor and the
stationary stator.
Clearance rate between the rotor and the stator.
Colloid mill is easy to clean after use.
High capacity and minimal requirements
No pressure is required for ionization.
easily adjustable.
Reduced wear as a result of the construction of the rotor-stator
with toughened steel/corundum.
[1,3]
9. DISADVANTAGE
It has no wide application in solids.
Wear of the rotating plates.
No fine grinding.
Consumes energy though still dependent on some factors.
[1,2]
10. CONCLUSION
Colloidal mill is highly recommended in
Pharmaceutical, beverage, paint, textiles,
and food processing industries, it can
produce high output in less time, easy to
operate and clean. A colloid mill is a
machine that used to reduce the particle
size of a solid in suspension in a liquid or
to reduce the droplet size in emulsions.
Colloid mills work on the rotor-stator
principle.
