Sub : Regarding Corruption in Taluk Office.

Respected Sir,

I am a resident of Arni. Last week I had been to Taluk Office to get

my Community Certificate where the officer asked for a bribery amount.

As a citizen of a country I refused to pay the money and came back. I was

often meeting many people in the Taluk Office, but all my efforts to get to

a community certificate ended in failure.

Finding no other go I paid the bribery amount and to my surprise

immediately I got my community certificate. These kinds of corruption

are prevalent in Taluk Office. Just imagine the people who are below

poverty line.

I have forwarded this message to District Collector also. If this

corruption is going to extend in the future, definitely we cant expect adeveloped status to our country.

Kindly take this issue into your consideration and take step

immediately to eradicate this evil from our society.

Thanking you,Yours faithfully,

calls were made on those days. They also showed us the earlier types of

organizing such a big unit. We will discuss about this when we meet next

GROUP DISCUSSION


30/76

GROUP DISCUSSION-I

TOPIC: Internet is a Boon or Bane

Group members involved in the group discussion were:

Surendar S, Surendiran M, Thongbam Lenon Singh, Valarmathi

R , Venigalla leela Krishnakant, Venkatesan G,Venkatesh A,

Vidhya P

Vidhya: Good morning friends, today our topic internet is an exercise in

hype I agree with it because nowadays everything is available in internet.

First thing which I want to clear here is what the exact Technical definition

of internet is- "Internet is the network of networks, very rapidly growing

that's why technology moves from IPV4 to IPV6", Because of this rapid

growth internet has huge chamber of knowledge, information, services

like e-commerce etc. provides human comforts.

Lenon: I would, however, like to contradict you .According to Defense it is

also a very dangerous weapons not only against the security of Countries

but also against the individuals.

One more example i want to give you is, a 10-15 year old child uses

internet for learning, gaming and knowledge purpose but one day

unfortunately he reached at one site which diverts his mind from studies,

outdoor games and whatever the extra activities required for his growth,

causes a very dangerous affects.

Surendar: As my friend said above everyone is right at their point, but itdepend on us how we use the internet. Yes it is sea of knowledge. Only

because of internet whole world is so closer. According to me there is no

such thing that we don't get from internet even it is business related or it

is tech related .everything is available on internet. So internet is a boon

for human being. isnt it is so.

Valarmathi: Apart from these positive aspects, it has the negative side

which people are using it in wrong way like Hacking which indicates to


31/76

cyber-crime and some strange sites to divert their mind to negative

thoughts and adult sites. So these are to be stopped for their misuse and

create awareness to people mainly youngsters.

Leela: As we know that everything has some positive side as well as

some drawback also. Same thing is applicable for internet also. Nowadays

we can't think our life without internet, whatever think we need

everything is available over here. We can see that every one searches

online for information and or to search products and get detailed

information on it and also much more new tech news.

Venkatesh: I like to endorse about the internet uses in India. Most of the

people misuse the internet and give a rise to cyber crime. Internet is both

a boon and a curse. If we use it in right way, it teaches us a lot. If we take

it in a wrong way it spoils us. But everybody here diverts their mind in

negative side.

Venkatesan: But I look in this way internet is not a curse, it is a very

large source of knowledge, for every age group such as child, teenagers,

adults etc. Internet gives us enough knowledge and gives more exposure

to the other side of the world. Today we are Web 2.0 it offers more things

to create by ourselves such as blogs. Internet provides several features a

lot of work can be done with in fraction of seconds and we save our most

precious time.

Surendiran : In my point of view it is not completely a curse to thesociety because it is source of livelihood to most of the MNC's where their

working strategy is based on internet. In case of students it helpful in

creating innovative projects with 100% information regarding the project.

Considering the use of internet in public offices, it helps in completing the

work quickly and efficiently so henceforth we need to make use of the

available technology judiciously and intellectuality.

Private Constructor

Private constructors are used to restrict the instantiation of object using 'new' operato

instance constructor. It is commonly used in classes that contain static members only.

This type of constructors is mainly used for creating singleton object.

If you don't want the class to be inherited we declare its constructor private.

We can't initialize the class outside the class or the instance of class can't be created

private.

We have to take help of nested class (Inner Class) or static method to initialize a class

Static Constructors

C# supports two types of constructor, a class constructor static constructor and an ins

constructor).

Static constructors might be convenient, but they are slow. The runtime is not smart e

way it can optimize inline assignments. Non-static constructors are inline and are fast

Static constructors are used to initializing class static data members.

Point to be remembered while creating static constructor:

1. There can be only one static constructor in the class.

2. The static constructor should be without parameters.

3. It can only access the static members of the class.

4. There should be no access modifier in static constructor definition.

Static members are preloaded in the memory. While instance members are post loade

Static methods can only use static data members.

Copy Constructor

This constructor takes a single argument: a reference to the object to be copied.

{

Complex c3 = new Complex();

publicvoid Method1()

{

Console.WriteLine("Method of a non-abstract class");

}

}

Constructor Chaining

The entire above program shows that C# supports constructor overloading. In C#, eve

constructor in the same class or in the base class of this class. This is what is known a

syntax is used for constructor chaining as follows.

// C# constructor chaining



58/76

using System;

class Complex

{

private Complex()

{

Console.Write("1");

}

private Complex(int x):this()

{

Console.Write("2");

}

public Complex(int x, int y):this(10)

{

Console.Write("3");

}

}

class MyClient

{


{

Complex c = new Complex(10,20); // Displays 123

}

}

In the above program the Complex(int x, int y) invokes the Complex(int x) constructor

this(arguments), which in turn invokes the Complex() constructor.

Static Constructors

The normal constructors, which we explained till now, can be used for the initialization

members. But C# provides a special type of constructor known as static constructor t

We can't use any access modifiers along with a static constructor.

Console.WriteLine("static constructor");}

}

Constructors & Inheritance

Both static and non-static constructors are not inherited to a derived class from a bas

// C# Implicit call of base class default constructor


using System;class Base

{

public Base()

{

Console.WriteLine("base constructor");

}

}class Derived : Base

{

}

class MyClient

{


{Derived d1 = new Derived();//Displays 'base constructor'


61/76

}

}

We can also call a base class constructor explicitly by using base() as shown below.

// C# Implicit call of base class default constructor


using System;

class Base

{

public Base()

{

Console.WriteLine("BASE 1");

}

public Base(int x)

{

Console.WriteLine("BASE 2");

}

}

class Derived : Base

{

public Derived():base(10)

{

Console.WriteLine("DERIVED CLASS");

}

}

class MyClient

{


{

Derived d1 = new Derived();//Displays 'base constructor'

}

}

This program outputs

The base() can be used for chaining constructors in a inheritance hierarchy.

Destructors

The .NET framework has an in built mechanism called Garbage Collection to de-allocat

objects. The destructor implements the statements to be executed during the garbag

function with the same name as the name of the class but starting with the character

NOISE POLLUTION


65/76

GENERAL PRESENTATION

ENVIRONMENTAL POLLUTION

INTRODUCTION:

Environmental pollution may be defined as, the unfavorable

alternation of our surroundings. It changes the quality of air, water and

land with the health of human and other life on earth.

Pollution are of different kinds depending on the nature of pollutant

generated from different sources.

Example:

Industry, automobiles, thermal power plants, farming, nuclear

reactors, generate different types of pollution to air, water bodies and

land.

TYPES OF POLLUTANTS:

Biodegradable pollutants

Non-degradable pollutants

CLASSIFICATION OF POLLUTANTS:

The different kinds of pollution that affects the environment are,

Air Pollution

Water Pollution

Soil Pollution

Marine Pollution

Noise Pollution Thermal Pollution


66/76

Nuclear Pollution

NOISE POLLUTION

INTRODUCTION:

Noise pollution is defied as, the unwanted, unpleasant or

disagreeable sound that cause discomfort for all living beings.

The sound intensity is measured in decibel (dB), which is tenth part

of the longest unit Bel. One dB is equal to the faintest sound, a human ear

can hear.

TYPES OF NOISE:

It has been found that environmental noise is doubling every 10

years. Generally noise is described as,

Industrial noise,

Transport noise,

Neighbourhood noise.

1). INDUSTRIAL NOISE:

Highly intense sound or noise pollution is caused by many machines.

There exists a long list of sources of noise pollution including different

machines of numerous factories, industries and mills. Industrial noise,

particularly from mechanical saws and pneumatic drill is unbearable and

is a nuisance to public.

Recently, it has been observed by the Institute of Oto-Rino

Laryngology, Chennai that enormously increasing industrial pollution has

damage the hearing of about 20% workers.


67/76

2). TRANSPORT NOISE:

The main noise, comes from transport. It includes road traffic noise,

rail traffic noise and air craft noise. The number of road vehicles like

motors, scooters, cars, motor cycles, buses, trucks and particularly the

diesel engine vehicles have increased enormously in recent years.

A survey conducted in metropolitan cities has shown that noise level

in Delhi, Bombay and Calcutta is as high as 90 dB. Inhabitants of cities are

subjected to this most annoying form of transport noise which gradually

deafens them.

3). NEIGHBOURHOOD NOISE:

This type of noise includes disturbance from household gadgets and

community. Common noise makers are musical loudspeakers etc., Ever

since the industrial revolution, noise in environment has been doubling

every ten years.

EFFECTS OF NOISE POLLUTION:

Noise pollution affects human health, comfort and efficiency. It

causes contraction of blood vessels, makes the skin pale, lands

to excessive secretion of adrenalin hormone into blood stream

which is responsible for high blood pressure. Blaring sounds have

known to cause mental distress, heart attacks neurological

problems, bith defects and abortion.

It cause muscles to contract leading to nervous breakdown,

tension etc.,


68/76

These adverse reactions are coupled with a change in hormone

content of blood, which in turn increase the rate of heart beat,constriction of blood vessels, digestive spasms and dilation of

pupil of eye.

It affects health efficiency and behaviour. It may cause damage

to heart, brain, kindneys, liver and may also produce emotional

disturbances.

When exposed to very loud and sudden noise acute damage

occurs to the ear drum.

In addition to serious loss of hearing due to excessive noise,

impulsive noise also causes psychological and pathological

disorders.

Ultrasonic sound can affect the digestive, respiratory, cardio

vascular systems and semicircular canals of the internal ear.

Brain is also adversely affected by loud and sudden noise as that

of jet and aero plane noise etc., people are subjected to

Psychiatric illness.

Recently it has been reported that blood is also thickened by

excessive noises.

It quit surprising that our optical system is also a prey for noise

pollution. Papillary dilation, impairment of night vision and

decrease in the rate of colour perception are some of its serve

effects.


69/76

EFFECTS OF NOISE POLLUTION:

1). SOURCE CONTROL:

This may include source modification such as acoustic treatment to

machine surface, design changes, limiting the operational timings and so

on.

2). TRANSMISSION PATH INTERVENTATION:

This may includes containing the source inside a sound insulating

enclosure, construction of a noise barrier or provision of sound absorbing

materials along the path.

3). RECEPTOR CONTROL:

This includes protection of the receiver by altering the work schedule

or provision of personal protection devices such as ear plugs for operating

noisy machinery. The measure may include dissipation and deflection

methods.

3). OILING:

Proper oiling will reduce the noise from the machines.

PREVENTIVE MEASURES:

Noise can be reduced by prescribing noise limits for vehicular

traffic, ban on honking of horns in certain areas and creation of

silent zones near schools and hospitals and redesigning of

buildings to make them noise proof.

Other measures can involve reduction of traffic density in

residential areas and giving preferences to mass public transport

system.

months employee and employer suffering & many of us bawling

because Lay-off in jobs.

Vinothkumar: Hai Dudes, if we saw news papers obviously

declared that IT firms face more problems. The main reason is

all outsourcing jobs we are getting from Us and Europe.

Nandhakumar: vinoth, you are right, US is ruining huge manyin Afghanistan and Iraq war. Even many banking sectors

become lost in present century decade.

Selvarsu: Hai Dears, i am really surprised from your dart

words. We are talking about employee and employers, but what

about the share holders and business mens? Those are fragile

a lot. It is drab life time for every one.

Rajeshkumar: Hi guys am happy to observe that all of your
