An emulsion is similar to a suspension only in that it is a mixture of two components. That is where the similarities end, however. Unlike a suspension, which can consist of two components of any phase, an emulsion is a mixture of two liquids.

Suspension are biphasic liquids dosage form in which insoluble solid particulate are uniformly distributed in liquid phase which may be stabilized by inclusion of suspending agents.
zebrafish are a workhorse as a translatable research model. And there are a multitude of assays in which they’ve shown promise.
The zebrafish is perhaps one of the most frequently used model organisms for genetic and developmental studies. The zebrafish is known for its unique regenerative abilities and rapid embryonic development.
The scientific name of zebrafish is Danio rerio and it belongs to the minnow family, Cyprinidae. The fish got its common name from the presence of five uniform and pigmented horizontal stripes on the side of its body, which resemble the stripes of a zebra. The characteristic stripes of zebrafish are blue in colour and they extend from the gill cover to the end of the caudal fin.
Scientists use fluorescent proteins as markers to more easily identify certain processes or reactions during microscopy research. Green fluorescent proteins (GFP), are used to create chimeric proteins which can be expressed in cells, tissues, and whole organisms. Using directed mutagenesis, fluorescence can emit in multiple wavelengths.
Fluorescent proteins are critical to research involving embryonic and larval zebrafish since they are transparent and develop nearly all organs and musculoskeletal structures six days after fertilization. Transparent embryos thus allow researchers to observe organs or tissues marked with tissue specific expressions of fluorescent proteins as they develop. Dozens of transgenic zebrafish lines have been created which express fluorescent proteins in organs, glands, and other bodily structures.

Emollients are moisturising treatments applied directly to the skin to soothe and hydrate it. They cover the skin with a protective film to trap in moisture.
Emollients are often used to help manage dry, itchy or scaly skin conditions such as eczema, psoriasis.
Emollients are available as:
Lotions – good for hairy or damaged areas of skin (such as weeping eczema) as they are thin and spread easily, but they're not very moisturising
Sprays – good for hard-to-reach areas and for sore or infected skin that shouldn't be touched; quickly absorbed
Creams – good for daytime use as they're not very greasy and are absorbed quickly
Ointments – good for very dry, thickened skin and for night-time use as they are greasy, thick and very moisturising; they're usually free of preservatives so are suitable for sensitive skin, but they shouldn't be used on weeping eczema
Bath Oils and Shower Products
Soap Substitutes
Leave-on emollients
Emollient lotions, sprays, creams and ointments should be applied directly to the skin. They should be smoothed, not rubbed, into the skin gently and in the same direction that your hair grows, to help prevent hair follicles from getting blocked.
They can be used to replace lost moisture whenever your skin feels dry or tight. They are very safe and you can't overuse them.
You may need to experiment with different emollients or try a combination. For example, you may decide to use a cream during the day and an ointment at night.

Thalidomide was first developed by CIBA, a Swiss pharmaceutical company in the early 1950s, and subsequently introduced as Contergan by Chemi Grunenthal.
The drug was initially advertised as a sedative which would allow users to undergo a deep sleep in the absence of a hangover and with a reduced risk of developing drug dependency. At the time, basic testing was done on the drug, and it was considered not to have any toxic effects on humans.
However, unlike today’s level of rigorous testing, the drug was not analyzed for any potentially dangerous teratogenic effects.
In the 1950s, scientists did not know that the effects of a drug could be passed through the placental barrier and harm a foetus in the womb, so the use of medications during pregnancy was not strictly controlled. And in the case of thalidomide, no tests were done involving pregnant women.
As the drug was traded under so many different names in 49 countries, it took five years for the connection between thalidomide taken by pregnant women and the impact on their children to be made. A UK Government warning was not issued until May 1962.
One reason why researchers and doctors were slow to make this connection was due to the wide range of changes to foetal development. Limbs, internal organs including the brain, eyesight and hearing could all be affected.The first time the link between thalidomide and its impact on development was made public in a letter published in The Lancet from an Australian doctor William McBride, in 1961.
The drug was formally withdrawn by Chemie Grünenthal on 26 November 1961 and a few days later, on 2 December 1961, the UK distributors followed suit. However, it remained in many medicine cabinets under many different names.
In the few short years that thalidomide was available, it's estimated that over 10,000 babies were affected by the drug worldwide. Around half died within months of being born. The thalidomide babies who survived and their families live with the effects of the drug.
The Thalidomide Society was formed in 1962 by the parents of children affected by the drug thalidomide. The original aim of the Society was to provide mutual support and a social network as well as to seek compensation.
In 1972, a highly publicised campaign led by the Sunday Times newspaper helped to secure a further settlement for children affected by thalidomide in the UK.
Thalidomide forced governments and medical authorities to review their pharmaceutical licencing policies. As a result, changes were made to the way drugs were marketed, tested and approved both in the UK and across the world.
One key change was that drugs intended for human use could no longer be approved purely on the basis of animal testing. And drug trials for substances marketed to pregnant women also had to provide evidence that they were safe for use in pregnancy.
Anagen :
Anagen is the active growth stage of hair.
During the anagen stage the hair contain it’s highest amount of melanin.
This stage is lasts between 3-6 years.
Catagen:
Catagen is a transition stage in which the hair stops growing but the hair is not shed.
During this stage the follicle is being reabsorbed .
This stage lasts 2-3 weeks.
Telogen:
Telegen is a resting stage during which the follicle receds and the hair begin to fall in preparation for the development of new hair.
This stage lasts between 6-8 weeks.
Anagen:
The hair growth cycle continues as anagen begins again.
The old hair has shed and a new follicle has formed.
A new hair begins growing to replace the hair that was shed.

Types of crystals & Application of x raykajal pradhan
some basic information:-
A crystal lattice is a 3-D arrangement of unit cells.
Unit cell is the smallest unit of a crystal, By stacking identical unit cells, the entire lattice can be constructed
A crystal’s unit cell dimensions are defined by six numbers, the lengths of the 3 axes, a, b, and c, and the three interaxial angles, α, β and γ.
If a unit cell has the same type of atom at the corners of the unit cell but not also in the middle of the faces nor in the centre of the cell, it is called primitive and given by symbol P

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
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.

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.
