Beijing is tackling its air pollution problem. Why can't New Delhi?

Delhi pollution problem

A decade ago, the capitals of Asia's two largest countries both had some of the dirtiest skies in the world. One the wrost days, millions were enveloped in thick grey canopies sf smig that darkened the sun and besieged the lungs.

Since then, one of those cities has made significant improvements. After the chinese government declared a war against pollution in 2013, Beijing pressed ahead with multiyear, $100 billion effort to clean its air. The authorities clamped down on factories, forced old vehicles off the road and shifted from coal to natural gas. Wgile more still needs to be done, Beijing officials say the city now has over100 more days of clear skies each year than when the campaign began.

But in the other city, New Delhi, the this autumn has been as foul as ever. the onset of air pollution season brought weeks

THE ART OF DEALING WITH PEOPLE Kundan timescale

Thinking creatively about human relations

All of us want two things out of life ; success and happiness.

all of us are different. your idea of success may be different from mine but there is one big factor which all of us must learn to deal with if we are to be successful and happy. the one common denominator to all success and happiness is other people.

Various scientific studies have proven that if you learn how to deal with other people, you will have gone 85% of they down the road to success in any bussiness, occupation, profession, and about 99% of the way to personal happiness

merely getting along isn"t the answer.

what is a way to deal with people thatt will bring us personal satisfaction and, at the same time not trample on others egos. human relations is the science of dealing with people in such a way that our egos and their egos remaiin intact. And this is the only method of getting along with people that ever results in any real success or satisfaction.

The reason 90% people fail in life is a failure to deal successfully with people.

look around you. Are the most successful people those with the most brain, the most skill? Are the people who are the happiest and get the most fun out of life so much smatter than other people you know? If you will stop and think a moment, the change are that you will say that the people you know who are the most successful and enjoy life the most, are those who' ''have a way '' with people

Your personality problems are your problems with other people.

there are millions of people today who are self conscious, shy, and ill-at-ease in social satutions. Tthey feel inferior and never realize that their real problem it never seems to get across to them that their failure in learning to deal with successfully with pwople.

there are almost many who, at least one the surface, seem to be vary opposite of the shy, reting type. they appear to be self-assured. They are ''bossy'' and dominate any social aituation they are in, whether it is the home, the office, or the club. Yet they,too, realise that aomething is missing. they wondered why their employees or their families do not appreciate them. they wonder why people do not co-operate move willingly; why it is necessary to continually force people into line. And, most of all, they realise in their more condid moments, that the pwople they are most anxius to impress never really give them the approval and acceptance they crave. they attempt to force co-opration, loyality and friendship; to push people to produce for them. But, the one thing can not force is the thing they want most, they can not force people to like them. they never really get what they want becuse they have never mastered the art of dealing with people.

whether we like it or not, people are here to stay.

in our modern world, we simply cannot achive any success or happiness without taking other people into account. The docter, the layer, the salse person who enjoy the most success is not necessarily the one who is most intelligent or most skillful machanics of his or her job. The husband and wife who attractive. look for a success in any endeavor amd you will find someone who has mastered the knack of dealing with people ... a person who has a ''way'' with other

skill in humsn relations is simillar to skill in any other field, in that success depends on unerstanding mastering certain basic general principales. you must not only know what to do, but why you're doing it.

As far as basic principles are concered, people are all the same. Yet each individual person you meet is different. If you attempted to learn some gimmick to deal successful with each seperate individual you met you would be faced with a hopeless task.

Influencing people is an art, not a gimmick.

When you apply gimmicks in superfical, mechanical manner, you go through the same motions as the person who ''has a way'' , but it doesn't work for you. The purpous of this book is to give you knowladge bassed upon an understanding of human nature : why the people act the way they do. the methods presented on this book have been tested on thousands of people who have attain my human relations seminars. They are not just my pet ideas of how you should deal with people, but ideas that have stood the test of how you must deal with people. That is if youi want to get along which them and get what you want at the same time.

yas we all want success and happiness. And the day is llong past, if it ever existed, when you could achieve these goals by forcing people to give you want. And begging is no better for no onne has respect for or any desire to help, the person who constantly kowtows and literally goes around with his hand out, begging other people to like him.

The successful way to get the things you want from life is to aquare skill in dealing with people. Read on and you will learn how.

Understanding The human ego

Because the human ego is such a precious thing to its possessor, and because a person will go to such

FLUORINE Kundan timescale

Chemical properties of fluorine , health effects of fluorine, and environmental effects

Fluorine F

Fluorine is a chemical element with the symbol F and atimic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremly reactive, as it reacts with all other elements except for argon neon and helium etc

Atomic number 9

Atimic mass. 18.998403 g.mol-1

Fluorine is an unvalent poisonous gaseous halogen, it pale yellow green and it is most chemically reactive and electronegative of all the elements. Fluorine readily forms compounds with mist other element even with noble gases krypton, xenon and radon. It is so reactive that glass, metals and even water, as well as other substances burn with bright flame in a jet of fluorine gas

In aqueous solution fluorune commonly occours as the fluoride ion F- fluoride are compounds that combine fluoride with some

Basic concepts of CHEMISTRY Kundan timescale

CHEMISTRY

It is branch if science which deals with the composition, structure qnd properties of matter.

Antoine laurent lavoisier is called the father if chemistry.

Branches of chemistry

1. Inorganic chemistry

Inorganic chemistry is concerned with the study of elements(other than carbon) and their compound.

2. Organic chemistry

Organic chemistry is the beanch of chemistry which concerned with organic compounds or substance produce by living organisms

3. Physical chemistry

Physical chemistry is concerned with the explanation of fundamental principles

4. Analytical chemistry

Analytical chemistry is the branch of chemistry which concerned with qualitative and quantitative analysis of the chemical substances.

In addition to these biochemistry, war chemistry, nuclear chemistry, forensic chemistry, earth chemistry etc., Are other branches of chemistry.

Matter

Anything which occupies some space and have some mass is called matter. It 15 made up of small particles which have space between them. The matter particle attract each other and are in a state of continuous motion.

Physical classification of matter

1. Solid

2. Liquid

3. Gas

Chemical classification of matter

1. Pure substances 2. Mixtures

a. Element

(1) metals

(2) non metals

(3) metalloids

b. Compund

(1) inorganic compound

(2) organic compounds

Elements

It is simplest form of pure substance which can neither be decomposed into nor build from simpler substances by ordinary physical and chemical methods. It contains elements known till date is 118.

Hydrogen is most abundant element in the universe.

Oxygen (46.6%), non metal, is the most qbundant element in the earth crust.

AL is most abundant metal in earth crust.

An element can be a metal or non-metal or a metalloid.

Symbols

A symbol is an abbreviation or shortened form for the full name of an element present aystem of symbols was introduced by Berzelius.

Symbol and latin names of some elements

Elements. Symbol. Latin name

Compound

It is also the form of matter which can be formed by combining two or more elements in a definite ratio by mass. It can be decomposed into its constituent elements by suitable chemical methods, e.g., water (H2O) is made of hydrogen and oxygen in the ratio of 1:8 by mass

Compound can be of two types

(1) inorganic compounds

Previously, it was believed that these compounds are derived from non-living sources, like rocks and and minerals. But these are infact the compounds of all the elements except hydrides of carbon (hydrocarbon) and their derivatives.

(2) organic compounds

According to earlier scientist, these compounds are derived from living source like plants and animals, or these remain burid under the earth (e.g., petroleum). According to modren concept these are hydrides of carbon and their derivatives.

Mixture

These are made up of two or more pure substances. They can be separated into their componants by some physical methods.

Mixture may be homogeneous (when composition is uniform throughout) or heterogeneous (when composition is not uniform throught).

Common methods for the separation of mixture are

(a) filtration filtration is the process of separating solids that are suspended in liquids by pouring the mixture into a filter funnel. As the liquid passes through the filter, the solid particles are held on the filter

(b) distillation distillation is the orocess if heating a liquid to form vapours and then cooling the vapours to get back the liquid. This is a method by which a mixture containing volatile substance can be separated into Its componants.

(c) sublimation This is the process of conversion of a solid directly into vapours on heating. Sunstances ahowing this property are called sublimation, e.g., iodine naphthalene camphor. This method is used to separate a sublimate substances.

(d) crystallization it is a process of separating solids having different solubilities in a particular solvent.

(e( magnetic separation Tills process is based upon the fact that a magnet attracts magnetic componants of a mixture of magnetic and non-magnetic substances. The non-magnetic substance rmains unaffected. Thus. It can be used to separated magnetic componants.

(f) Atmolysis Tills method is based upon rates of diffusion of gases and used for their separation from a gases mixture.

Atom and molecules

Atom is the smallest particle of an element which can take part in the chemical reaction. It major may not capable of independent existance.

Molecule is the simplest particle of matter that has independent existance. It may be monoatomic e.g., H2, cl2 N2 (diatomic) O3(triatomic) or hetroatomic, e.g., HCl, NH3, ch3 etc.

Physical quantities and their measurments units

To express the measurement of any physical quantity two things are considered:

(1) its unit,

(2) the numerical.

Magnitude of physical quantity= numerical value * unit

Units are of two types:

(1) basic units

(2) derived units

1. The basic or fundametal units are those of length (m), ass (kg), time (s) electric current (A), thermodynamic temperature(K), amount of substance (mol), and luminous intensity(cd).

2. Derived units are basically derived from the fundametal units, e.g., units of density is derived from units of mass and volume.

The systems used for describing measurments of various physical quantities are

(a) cgs system it is based on centimetre, gram and second as the units of length, mass and time respectively.

(b) FPS system A British system which used foot(ft). pound (Ib) and second (s) as the fundamental units of length, mass qnd time.

(c) MRS system Uses metre(m) kilogram (kg) and second (s) respectively for lengh mass and time, ampere(A) was added later on for electric current.

(d) SI system (1960) International system of units and contains following seven basic and two supplementary units:

Basic physical quantities and their corresponding basic units

Supplementary units it includes plane angle in radian and solid angle in steradian

Prefixes

The units of some physical quantities are either too amall or too large to change the order of magnitude. These are expressed by using prefixes befor the name of base units. The various perfixes are listed as

Dimension analysis

often while calculating, there is a need to convert unit from one system to other the method used to accomplish this is called factor label method or unit factor methode or dimensional analysis.in in this,

information sought = information given * conversion factio

important conversion factor

scientific notation

in such notation, all measurements (however large or small) are expressed

as a number between 1.000 and 9.999 multiplied or divided by 10. In general as

N*10 here N is known as exponent e g., 138.42 can be written as 1.3842 * 10-4

Precision and accurcy

Precision refers the closeness of the set of vale obtained from identical measurments of quantity. Precision is simply a measure of reproduciblity of an expriment.

Precision = individual vale - arithmetic mean value accuracy = mean- value

In physical measurments, accurate results are generally precise but precise results need not be accurate. Other words good precision does not assure good accuracy.

In measurements accrate results are generally precise results need not be accurate in other words good precision does not assure good accuracy

significant figures

significant figure are meaningfull digits includs all those digits that are known with certainity plus one more is uncertain or estimated

Grater the number of significant figure in a measurment smaller the uncertainity

1. An digit are significant except zero in the beginning of a number.

2. zeros to the right of the decimal point are significant e.g., 0.132, 0.0132 and 15.0, all have three significant figures.

PERSISTENCE. Kundan Timescale

PERSISTENCE

Persistence is essential factor inthe procedure of transmuting DESIRE into its monetary equvalent the basis of persistance is the power of will

Will power and desire when properly combined make an irresistible pair men who accumulate grate fortune are generally known as cold blooded and sometime ruthless ofen they are mis understand what they have is will power which they mix with oersistance and place back to their desire to insure the attainment of their objectives

Henrey ford has been generally misunderstand to be ruthless and cold blooded this mis conception grew out of Ford's habit of following through in all his plans with persistance the majority of people are ready to through their aim and purpose overboard and give up at the first aim of opposition or misfortune a few carry on despite all opposition , untile they attin their goal these few are the ford carnegies, Rockefeller and editoions
