RATIONALE

With the increasing variety of options and opportunities emerging for Diploma

students, fulfilling their communication needs become highly important. Proficiency in

communication can equip them to be confident and to cope with the employment and

educational situation in any part of the world. Communication levels inspire higher

aspiratory levels in the process of upward mobility in career and socio-cultural evolution

of the young individuals. At the end of the course the student should be able to express

himself in oral and written communication effectively.

SPECIFIC INSTRUCTIONAL OBJECTIVES

All the four skills - listening, speaking, reading and writing - should be developed

in the communication process for a polytechnic student who is at the intermediate level

and transitional period from school to college.

Silent reading of the English text book acquaints him with the grammatical

structures and the nuances of the language indirectly and also triggers reaction in the

thinking process according to the student’s specific learning background. Loud

reading equips the student with confidence and practice for oral communication. Both

these should be given due importance in the class room situation.

Developing listening skills equip them with the necessary focus in understanding

oral communication without difficulty to react and interact properly. Proper exposure in

developing these two skills facilitates speaking and writing which are very essential in day

to day interaction in any official, social or personal context. Matching to the entry level

quality of the polytechnic student and his technical background, this text book is aimed at

fulfilling the needs of all the four communication skills with suitable texts, language

exercises and activities. Grammar items prescribed in the syllabus are embedded in the prescribed texts to

make the teaching learning process contextualised and activity based to ensure proper

textual orientation. Exercises and group activities are given in the text itself for the

students to get practiced.

RATIONALE:

In diploma level engineering education skill development plays a vital role. The skill development can be achieved by on hand experience in handling various instruments, apparatus and equipment. This is accomplished by doing engineering related experiments in practical classes in various laboratories.

GUIDELINES:

All the ten experiments given in the list of experiments should be completed and given for the end semester practical examination.

In order to develop best skills in handling Instruments/Equipment and taking readings in the practical classes, every two students should be provided with a separate experimental setup for doing experiments in the laboratory.

The external examiners are requested to ensure that a single experimental question should not be given to more than four students while admitting a batch of 30 students during Autonomous Examinations.

Plumbing is the skilled trade of working with pipes, tubing and plumbing fixtures for drinking water systems and the drainage of waste.

The plumbing industry is a basic and substantial part of every developed economy due to the need for clean water, and proper collection and transport of wastes.

Plumbing also refers to a system of pipes and fixtures installed in a building for the distribution of potable water and the removal of waterborne wastes.

Plumbing is usually distinguished from water and sewage systems, in that a plumbing system serves one building, while water and sewage systems serve a group of buildings or a city.

To install pipes and fixtures.

Exercises • Sink install. • Pipe cutting & Fitting. • External Thread cutting.

Mr. Nair was addressing the inaugural session of the 8th International Conference on

‘Low Cost Planetary Missions’ here. He said ISRO was poised to launch the Chandrayaan-2

mission to land on the Moon and conduct experiments in 2012-13. This would be followed by a

manned expedition to the Moon in 2015 and plans to explore Mars, later.

The five-day conference, organized by ISRO in collaboration with the International

Academy of Astronautics (IAA) and the Astronautically Society of India (ASI), was

inaugurated by Chief Minister Mr. Digambar Kamat. The Goa Minister for Science and

Technology Mr. Churchill Alemao was also present.

Speaking about low-cost planetary missions, Mr. Nair said India had set a trend in

building low-cost satellites with Chandrayaan-1 being the best example. It was below $100

million as compared to the nearly $500 million that were spent on similar expeditions by other

developed countries.

The solar system

Our solar system consists of the sun, the nine planets and the asteroids, comets

and meteoroids that are associated with the planets. The nine planets that make up our

solar system are Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune and Pluto.

Mercury is closest to the sun. It is hot and dry. Venus is one of the brightest objects in the

sky after the sun and the moon. Venus is also the hottest planet in the solar system. Next

is the Earth, the only living planet. After Earth is Mars which is also called the Red

Planet. Mars is very dry now.

Jupiter is the largest planet. Its bright colour comes from its clouds. Saturn is

the second largest planet and has wide rings. The planet Uranus is a bright blue colour.

After Uranus is Neptune. Neptune rotates around the sun once in every 164 years. Pluto

is the farthest planet from the sun.

RATIONALE:

In diploma level Engineering education skill development plays a vital role. The skill development can be achieved by on hand experience in handling various instruments, apparatus and equipment. This is accomplished by doing engineering related experiments in practical classes in various laboratories.

GUIDELINES:

All the ten experiments given in the list of experiments should be completed and given for the end semester practical examination.

In order to develop best skills in handling Instruments/Equipment and taking readings in the practical classes, every two students should be provided with a separate experimental setup for doing experiments in the laboratory.

The external examiners are requested to ensure that a single experimental question should not be given to more than three students while admitting a batch of 30 students during Autonomous Examinations.

Plumbing is the skilled trade of working with pipes, tubing and plumbing fixtures for drinking water systems and the drainage of waste.

The plumbing industry is a basic and substantial part of every developed economy due to the need for clean water, and proper collection and transport of wastes.

Plumbing also refers to a system of pipes and fixtures installed in a building for the distribution of potable water and the removal of waterborne wastes.

Plumbing is usually distinguished from water and sewage systems, in that a plumbing system serves one building, while water and sewage systems serve a group of buildings or a city.
