There are two types of atomic bonds - ionic bonds and covalent bonds.pdfaswrd
There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their
structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and
bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 -
200 kcal/mol). Whether two atoms can form a covalent bond depends upon their
electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two
atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the
atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and
negatively charged ion (anion). The bond between these two ions is called an ionic bond.

Polarity:LowHigh
Formation:A covalent bond is formed between two non-metals that have similar
electronegativities. Neither atom is \"strong\" enough to attract electrons from the other. For
stabilization, they share their electrons from outer molecular orbit with othersAn ionic bond is
formed between a metal and a non-metal. Non-metals(-ve ion) are \"stronger\" than the

In terms of structure A purine is a heterocyclic aromatic compound.pdfaswrd
In terms of structure : A purine is a heterocyclic aromatic compound that consists of a pyrimidine
ring fused to a imidazole ring.It consists of 2 carbon- nitrogen rings together with four nitrogen
atoms whereas pyrimidine is a heterocyclic aromatic compound consisting of nitrogen atoms that
are present on 1st and 3rd position of the ring.So,pyrimidine contains 1 carbon- nitrogen ring and
two nitrogen atoms.
In terms of molecular weight: Molecular weight of purine is 120.11 g/mol whereas molecular
weight of pyrimidine is 80.088 g/mol.
The pneumonic device that can be used to memorise which bases are purines vs pyrimidines are :

In virtually every decision they make, executives today consider some kind of forecast. Sound
predictions of demands and trends are no longer luxury items, but a necessity, if managers are to
cope with seasonality, sudden changes in demand levels, price-cutting maneuvers of the
competition, strikes, and large swings of the economy. Forecasting can help them deal with these
troubles; but it can help them more, the more they know about the general principles of
forecasting, what it can and cannot do for them currently, and which techniques are suited to
their needs of the moment. Here the authors try to explain the potential of forecasting to
managers, focusing special attention on sales forecasting for products of Corning Glass Works as
these have matured through the product life cycle. Also included is a rundown of forecasting
techniques.
Strategic planning focuses largely on managing interaction with environmental forces, which
include competitors, government, suppliers, customers, various interest groups and other factors
that affect your business and its prospects. Your ability as a small business owner-manager to
deal with these groups will vary widely depending on the group and on the timing. Also, you
may be able to get more of what you want from a supplier than from a competitor (although size,
distance, the percentage of the supplier\'s business you represent and your record of
dependability as a customer can affect this relationship). How you manage these and other
relationships is one of the decisions you will make during the strategic planning process.
Because of major changes in the business environment, your familiarity with strategic planning
and your ability to implement it is critical. At one time, business owner-managers assessed the
environment on a continuum that ran between very stable and very unstable. Businesses, such as
the producers of automobiles, furniture and other consumer goods, operated in a relatively stable
and predictable world. This also was true of many service firms, such as banks and savings and
loans. Typically, the environment included competition that was limited to a stable group of
competitors, loyal customers and a relatively slow transfer of information. Many small
businesses could thrive in this environment. Other small investors entered fields such as
xerography, computers and computer component production, software design and chemical
research. Some of these grew rapidly, becoming names with which we all are familiar: Xerox,
IBM, Apple and Microsoft. But many more failed.
Today, experts agree that more businesses face an unstable business environment. Improvements
in information processing and telecommunications have made major changes in most industries.
Along with this, improvements in transportation and the growth of foreign economies
(specifically in Europe and Asia) have created a global marketplace and redefined certain
industries. In addition, as consumers are exposed to more choices, loy.

Five broad principles guide AARP’s evaluation of tax options. Propos.pdfaswrd
Five broad principles guide AARP’s evaluation of tax options. Proposals to reform the tax code,
stimulate the economy, raise additional revenue for any purpose, or modify specific tax
provisions should take into account these principles. Equity—Revenue-raising methods should
consider people’s ability to pay and should, to the extent possible, achieve vertical and horizontal
equity. Taxation should be progressive, and people with comparable incomes should be taxed at
comparable rates. Taxes may also be related to benefits derived from government services.
Economic neutrality—Taxes should be as neutral as possible in their treatment of economic
activity and should not unduly encourage behavior undertaken simply to avoid taxation. Often
this can be achieved by a combination of a broad taxable base and a low tax rate. In addition
taxes should not unduly hinder economic growth, induce inflation, or discourage savings. Taxes
may be used to mitigate economic costs imposed on society that were not fully captured through
market prices. Administrative efficiency—Taxes should be simple for taxpayers to understand
and comply with, and as easy as possible to administer. The need to collect data on taxpayers and
enforce tax laws should be balanced against the protection of individual liberties and privacy.
Revenue—The tax system must produce sufficient revenue to pay for important national, state,
and local priorities and maintain fiscal stability. Stable and reliable public policies and programs
require adequate and consistent sources of revenue. Social and other policy goals—A balance
must be struck between using the tax system to address social policy goals (through such
measures as tax expenditures or earmarking revenue) and raising adequate revenues simply and
equitably. Sometimes the above principles conflict with each other. In these cases AARP may
weigh the relative importance of each of the key principles. AARP’s position on tax policies take
into account the net fiscal impact of a given policy proposal, not only its tax component.
Economic neutrality—Typically taxes create some inefficiencies by distorting economic choices
and thus people’s behavior in the market. One major goal of most tax reform proposals is to
reduce these distortions and encourage stronger economic growth. Proponents of consumption
taxes note that income taxes encourage consumption over saving. Integrating the individual and
corporate income taxes would reduce distortions that influence how businesses are organized and
how income is transferred from corporations to shareholders. By eliminating certain tax
deductions and other preferences, fundamental restructuring of the current income tax would also
improve the neutrality and efficiency of the tax system. Administrative efficiency—The degree
of administrative complexity depends greatly on the form of the tax. A VAT can have high
administrative costs because it increases the number of taxpayers and requires detailed record
ke.

ASRASR is an expansive form of reaction between silica in aggrega.pdfaswrd
ASR:
ASR is an expansive form of reaction between silica in aggregates potassium and sodium alkalis
mostly from cement but also from aggregates, pozzolons admixtures and mixing water. The
reactivity is potentially harmful when it produces significant expansion. indication of presence of
alkali aggregate reactivity may be a network of closed and spall joints. or movement of portion
of structure.ASR can be controlled through a proper selection of aggregates.
Sulphate attack:
Excessive amount of sulphates in soil and water may attack concrete by reacting with hydrated
compounds in hydrant cement paste. these reactions can induce sufficient pressure to disintegrate
concrete. sulphate attck is more common where the concrete is subjected to both drying and
wetting for the best defence against the external sulfate attack.
DEF:
Delayed Ettringite formation is a special form of sulfate internal attack it occurs in concrete
which can be cured at delayed temperature for example where steam curing has been used. it was
originally identified in steam cured concrete sleepers. It causes Expansion of concrete due to
Etringite formation within the paste and can cause serious disintegration. DEF generally occurs
when the Ettringite crystals exert an expansive force. the total amount of ettingite formed during
hydration is decomposed.
Freezing/ Thawing:
The most potentially disrupting feature is freezing and thawing while concrete is wet particularly
in presence id decieng chemicals the detoriation is caused by freezing of water and subsequent
expansion of the paste during freezing water is displaced by ice formation in the paste so that is
accomodated and that is not disruptive. Microscopic air bubbles form the space for water to enter
and thus relieve the hydraulic pressure generated the concrete with low water cement ratio is
durable the concret with high cementatious ratio air entrained concrete with low water cement
ratio withstands great number of cycles to freezing and thawing.
Corrosion:
The concrete protects the embedded steel with its highly alkaline nature High PH Environment in
concrete causes the highly passive & non corroding protective oxide film to form on steel.
However the chlorides from sea water can destroy and penetrate the film once chloride corrosion
threshhold is reached the an electric cell is formed along steel between steel bars and electro

ASRASR is an expansive form of reaction between silica in aggrega.pdfaswrd
ASR:
ASR is an expansive form of reaction between silica in aggregates potassium and sodium alkalis
mostly from cement but also from aggregates, pozzolons admixtures and mixing water. The
reactivity is potentially harmful when it produces significant expansion. indication of presence of
alkali aggregate reactivity may be a network of closed and spall joints. or movement of portion
of structure.ASR can be controlled through a proper selection of aggregates.
Sulphate attack:
Excessive amount of sulphates in soil and water may attack concrete by reacting with hydrated
compounds in hydrant cement paste. these reactions can induce sufficient pressure to disintegrate
concrete. sulphate attck is more common where the concrete is subjected to both drying and
wetting for the best defence against the external sulfate attack.
DEF:
Delayed Ettringite formation is a special form of sulfate internal attack it occurs in concrete
which can be cured at delayed temperature for example where steam curing has been used. it was
originally identified in steam cured concrete sleepers. It causes Expansion of concrete due to
Etringite formation within the paste and can cause serious disintegration. DEF generally occurs
when the Ettringite crystals exert an expansive force. the total amount of ettingite formed during
hydration is decomposed.
Freezing/ Thawing:
The most potentially disrupting feature is freezing and thawing while concrete is wet particularly
in presence id decieng chemicals the detoriation is caused by freezing of water and subsequent
expansion of the paste during freezing water is displaced by ice formation in the paste so that is
accomodated and that is not disruptive. Microscopic air bubbles form the space for water to enter
and thus relieve the hydraulic pressure generated the concrete with low water cement ratio is
durable the concret with high cementatious ratio air entrained concrete with low water cement
ratio withstands great number of cycles to freezing and thawing.
Corrosion:
The concrete protects the embedded steel with its highly alkaline nature High PH Environment in
concrete causes the highly passive & non corroding protective oxide film to form on steel.
However the chlorides from sea water can destroy and penetrate the film once chloride corrosion
threshhold is reached the an electric cell is formed along steel between steel bars and electro
chemical process of carrions begins.

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 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.
