The ammonia molecule (NH3) has three pairs of electrons involved in bonding, but
there is a lone pair of electrons on the nitrogen atom. It is not bonded with another atom;
however, it influences the overall shape through repulsions. As in methane above, there are four
regions of electron density. Therefore, the overall orientation of the regions of electron density is
tetrahedral. On the other hand, there are only three outer atoms. This is referred to as an AX3E
type molecule because the lone pair is represented by an E. The observed shape of the molecule
is a trigonal pyramid, because the lone pair is not \"visible\" in experimental methods used to
determine molecular geometry. The shape of a molecule is found from the relationship of the
atoms even though it can be influenced by lone pairs of electron

Cooperativity Two different theories of the coo.pdfbrijmote
Cooperativity : Two different theories of the cooperative mechanism were
postulated. One was the theory of Monod, Wyman, and Changeux,MWC model (“symmetry”or
“concerted”or “the two-state” model),and the other was the theory of Koshland, Nemethy, and
FilmerKNF model (“induced fit”or“sequential”model). The MWC model proposed that the
subunits changed shape in a concerted manner to preserve the symmetry of the entire molecule
as it was transformed from one conformation (T) to a second conformation (R) under the
influence of ligand. The KNF model postulated that each subunit changed shape as ligand bound,
so that changes in one subunit led to distortions in the shape and/or interactions of other subunits
of the protein. The KNF model, however, also predicted that in some cases the first ligand to
bind could make it more difficult for subsequent ligands to bind. This was called “negative
cooperativity” because there was (a) “cooperativity” between the subunits and (b) “negative”
because binding of one ligand made the binding of subsequent ligands more difficult.The MWC
theory allowed no such alternative. Because only the KNF theory fit negatively cooperative
enzymes, it is easy to select that model for such enzymes, but because both theories fit positively
cooperative enzymes more sophisticated tools must be applied to such cases.

Earlier a place value notation number system had evolved over a leng.pdfbrijmote
Earlier a place value notation number system had evolved over a lengthy period with a number
base of 60. It allowed arbitrarily large numbers and fractions to be represented and so proved to
be the foundation of more high powered mathematical development.
Number problems such as that of the Pythagorean triples (a,b,c) with a2+b2 = c2 were studied
from at least 1700 BC. Systems of linear equations were studied in the context of solving number
problems. Quadratic equations were also studied and these examples led to a type of numerical
algebra.
Geometric problems relating to similar figures, area and volume were also studied and values
obtained for π.
The Babylonian basis of mathematics was inherited by the Greeks and independent development
by the Greeks began from around 450 BC. Zeno of Elea\'s paradoxes led to the atomic theory of
Democritus. A more precise formulation of concepts led to the realisation that the rational
numbers did not suffice to measure all lengths. A geometric formulation of irrational numbers
arose. Studies of area led to a form of integration.
The theory of conic sections shows a high point in pure mathematical study by Apollonius.
Further mathematical discoveries were driven by the astronomy, for example the study of
trigonometry.
The major Greek progress in mathematics was from 300 BC to 200 AD. After this time progress
continued in Islamic countries. Mathematics flourished in particular in Iran, Syria and India. This
work did not match the progress made by the Greeks but in addition to the Islamic progress, it
did preserve Greek mathematics. From about the 11th Century Adelard of Bath, then later
Fibonacci, brought this Islamic mathematics and its knowledge of Greek mathematics back into
Europe.
Major progress in mathematics in Europe began again at the beginning of the 16th Century with
Pacioli, then Cardan, Tartaglia and Ferrari with the algebraic solution of cubic and quartic
equations. Copernicus and Galileo revolutionised the applications of mathematics to the study of
the universe.
The progress in algebra had a major psychological effect and enthusiasm for mathematical
research, in particular research in algebra, spread from Italy to Stevin in Belgium and Viète in
France.
The 17th Century saw Napier, Briggs and others greatly extend the power of mathematics as a
calculatory science with his discovery of logarithms. Cavalieri made progress towards the
calculus with his infinitesimal methods and Descartes added the power of algebraic methods to
geometry.
Progress towards the calculus continued with Fermat, who, together with Pascal, began the
mathematical study of probability. However the calculus was to be the topic of most significance
to evolve in the 17th Century.
Newton, building on the work of many earlier mathematicians such as his teacher Barrow,
developed the calculus into a tool to push forward the study of nature. His work contained a
wealth of new discoveries showing the interaction between mathemat.
Cyclohexanone is slightly soluble in water.NaCl is added to make t.pdfbrijmote
Cyclohexanone is slightly soluble in water.
NaCl is added to make the aqueous medium more polar so that the solubility of cyclohexanone in
the aqueous layer is decreased.
This will increase the partition coefficient and more cyclohexanone will be extracted into the
organic layer.
Thus the extraction of cyclohexanone will be more efficient.
Solution
Cyclohexanone is slightly soluble in water.
NaCl is added to make the aqueous medium more polar so that the solubility of cyclohexanone in
the aqueous layer is decreased.
This will increase the partition coefficient and more cyclohexanone will be extracted into the
organic layer.
Thus the extraction of cyclohexanone will be more efficient..

Amniotes
:They are a clade of tetrapod vertebrates including the reptiles, flying creatures, and warm
blooded animals that lay their eggs ashore or hold the prepared egg inside the mother. They are
recognized from the anamniotes (fishes and creatures of land and water), which commonly lay
their eggs in water. Amniotes are tetrapods (relatives of four-limbed and backboned creatures)
that are portrayed by having an egg outfitted with an amnion, an adjustment to lay eggs ashore as
opposed to in water as the anamniotes (counting frogs) regularly do. Amniotes incorporate
synapsids (warm blooded creatures alongside their wiped out family) and sauropsids (reptiles
and winged creatures), and additionally their predecessors. Amniote developing lives, whether
laid as eggs or conveyed by the female, are ensured and supported by a few broad layers. In
eutherian warm blooded creatures, (for example, people), these films incorporate the amniotic
sac that encompasses the embryo. These embryonic films and the absence of a larval stage

trademark hormones called ecdysteroids
the fingernail skin has 3 layers epicuticle, exocuticle, and endocuticle

Some taxa have lost the genuine coelom and have gotten to be blastocoelic (pseudocoelomic).

Cooperativity Two different theories of the coo.pdfbrijmote
Cooperativity : Two different theories of the cooperative mechanism were
postulated. One was the theory of Monod, Wyman, and Changeux,MWC model (“symmetry”or
“concerted”or “the two-state” model),and the other was the theory of Koshland, Nemethy, and
FilmerKNF model (“induced fit”or“sequential”model). The MWC model proposed that the
subunits changed shape in a concerted manner to preserve the symmetry of the entire molecule
as it was transformed from one conformation (T) to a second conformation (R) under the
influence of ligand. The KNF model postulated that each subunit changed shape as ligand bound,
so that changes in one subunit led to distortions in the shape and/or interactions of other subunits
of the protein. The KNF model, however, also predicted that in some cases the first ligand to
bind could make it more difficult for subsequent ligands to bind. This was called “negative
cooperativity” because there was (a) “cooperativity” between the subunits and (b) “negative”
because binding of one ligand made the binding of subsequent ligands more difficult.The MWC
theory allowed no such alternative. Because only the KNF theory fit negatively cooperative
enzymes, it is easy to select that model for such enzymes, but because both theories fit positively
cooperative enzymes more sophisticated tools must be applied to such cases.

Earlier a place value notation number system had evolved over a leng.pdfbrijmote
Earlier a place value notation number system had evolved over a lengthy period with a number
base of 60. It allowed arbitrarily large numbers and fractions to be represented and so proved to
be the foundation of more high powered mathematical development.
Number problems such as that of the Pythagorean triples (a,b,c) with a2+b2 = c2 were studied
from at least 1700 BC. Systems of linear equations were studied in the context of solving number
problems. Quadratic equations were also studied and these examples led to a type of numerical
algebra.
Geometric problems relating to similar figures, area and volume were also studied and values
obtained for π.
The Babylonian basis of mathematics was inherited by the Greeks and independent development
by the Greeks began from around 450 BC. Zeno of Elea\'s paradoxes led to the atomic theory of
Democritus. A more precise formulation of concepts led to the realisation that the rational
numbers did not suffice to measure all lengths. A geometric formulation of irrational numbers
arose. Studies of area led to a form of integration.
The theory of conic sections shows a high point in pure mathematical study by Apollonius.
Further mathematical discoveries were driven by the astronomy, for example the study of
trigonometry.
The major Greek progress in mathematics was from 300 BC to 200 AD. After this time progress
continued in Islamic countries. Mathematics flourished in particular in Iran, Syria and India. This
work did not match the progress made by the Greeks but in addition to the Islamic progress, it
did preserve Greek mathematics. From about the 11th Century Adelard of Bath, then later
Fibonacci, brought this Islamic mathematics and its knowledge of Greek mathematics back into
Europe.
Major progress in mathematics in Europe began again at the beginning of the 16th Century with
Pacioli, then Cardan, Tartaglia and Ferrari with the algebraic solution of cubic and quartic
equations. Copernicus and Galileo revolutionised the applications of mathematics to the study of
the universe.
The progress in algebra had a major psychological effect and enthusiasm for mathematical
research, in particular research in algebra, spread from Italy to Stevin in Belgium and Viète in
France.
The 17th Century saw Napier, Briggs and others greatly extend the power of mathematics as a
calculatory science with his discovery of logarithms. Cavalieri made progress towards the
calculus with his infinitesimal methods and Descartes added the power of algebraic methods to
geometry.
Progress towards the calculus continued with Fermat, who, together with Pascal, began the
mathematical study of probability. However the calculus was to be the topic of most significance
to evolve in the 17th Century.
Newton, building on the work of many earlier mathematicians such as his teacher Barrow,
developed the calculus into a tool to push forward the study of nature. His work contained a
wealth of new discoveries showing the interaction between mathemat.

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.
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.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
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.
