It defines water harvesting as capturing freshwater sources like rainwater and runoff and storing it for uses like irrigation, drinking water, and groundwater recharge. Rainwater harvesting specifically refers to collecting rainwater from rooftops or land surfaces and storing it. There are rural and urban models of rainwater harvesting in India. Watershed management aims to sustainably manage land, vegetation, and water resources within a drainage area. It outlines objectives, parameters, and practices like conserving soil/water, improving water retention, growing greenery, and structures like contour bunds and check dams.

PROJECT ON RAIN WATER HARVESTING.pptx
This document summarizes a student project on rainwater harvesting. It defines rainwater harvesting as collecting water from surfaces where rain falls and storing it for later use, usually from rooftops. Benefits include being inexpensive and providing a continuous local water source. Challenges are limited supply due to rainfall variability. Systems include catchment areas, collection/storage tanks, and conveyance systems to transfer water. The document provides diagrams and examples of rainwater harvesting and its importance for agriculture, livestock, meeting water demands, and preventing waterlogging and soil erosion. It suggests starting with government and public buildings to test effectiveness before broader implementation.
Rainwater harvesting
Rainwater harvesting involves collecting, conveying, and storing rainwater from rooftops and other surfaces. It can provide a supplemental source of water for uses like irrigation, production, and drinking water by capturing and storing rainwater or recharging local groundwater. Effective rainwater harvesting systems consist of components to collect water from surfaces, convey it, filter it, and store it in tanks or recharge it into the groundwater through structures. These systems aim to conserve and supplement existing water resources in a low-cost way while helping to replenish groundwater levels. However, performance depends on climate and collected water quality may be impacted by external factors if not properly maintained.

Intrenet and its uses
The document provides an overview of the Internet and how it works:
- The Internet is a global network that allows computers to share information electronically. It can be accessed from anywhere through an Internet connection.
- Web pages are identified by URLs and displayed in web browsers like Safari, Internet Explorer, Google Chrome, and Mozilla Firefox. A URL includes the protocol, server, path, and resource name.
- The Internet has grown from ARPANET in the 1960s and key developments like the introduction of email, the World Wide Web, and graphical web browsers. It enables access to information through various services like web pages, email, file transfers, messaging, and voice calls.
Fuel cells and its types
The document discusses fuel cells, including:
1) A fuel cell generates electricity through an electrochemical reaction between a fuel (typically hydrogen) and oxygen, with water and heat as byproducts.
2) Fuel cells have several types but all consist of an anode, cathode, and electrolyte; they operate by separating the fuel from the oxygen to prevent combustion.
3) Applications include stationary power systems, transportation such as fuel cell vehicles and buses, and portable power devices, with each fuel cell type suited to certain uses.
Switch statement, break statement, go to statement
The document discusses various control flow statements in C programming including switch case statement, break statement, and goto statement. It provides the syntax and meaning of switch case statement which allows executing different code blocks based on the value of an expression. It also explains the break statement which terminates the execution of a switch case or loop statement. The goto statement allows transferring program control unconditionally to another label in the program.
Isomorphism
This document discusses isomorphism, one-to-one and onto linear transformations, and provides examples. It defines isomorphism as when two vector spaces are said to be isomorphic if there exists a linear transformation between them that is both one-to-one and onto. It provides theorems relating the dimension of isomorphic spaces and characterizations of one-to-one and onto linear transformations in terms of the kernel, rank, and nullity. Examples are given to determine whether linear transformations are one-to-one and/or onto based on their rank and nullity. Finally, several vector spaces are stated to be isomorphic to each other.
3 d-printing
This document discusses the intellectual property implications of 3D printing. It summarizes that under UK law, design rights, patents, and trademarks are not infringed by personal or non-commercial use of 3D printers. Copyright protection also does not typically apply to most 3D objects that could be reproduced. While control of IP may become problematic as 3D printing technologies improve and designs/files are more openly shared, currently disseminating design files does not clearly infringe upon patents or copyrights in those files under UK law. The document provides an overview of the relevant IP laws and concludes that the legal outlook suggests private and non-commercial 3D printing will not usually infringe upon intellectual property rights.
Linear transformation.ppt
This document discusses linear transformations and their properties. It defines a linear transformation as a function between vector spaces that preserves vector addition and scalar multiplication. The kernel of a linear transformation is the set of vectors mapped to the zero vector, and is a subspace of the domain. The range is the set of images of all vectors under the transformation. Matrices can represent linear transformations, with the matrix equation representing the transformation of vectors. Examples are provided to illustrate key concepts such as kernels, ranges, and matrix representations of linear transformations.

This document discusses various aspects of communication skills, with a focus on pronunciation and voice modulation. It provides tips for proper pronunciation, the importance of pronunciation in communication. It also discusses voice modulation techniques like volume, pitch, pace, emphasis and inflection. The document emphasizes using pauses to allow listeners to absorb information and to replace filler words. Pauses also help speakers organize their thoughts and allow their mind to "catch up" to their speech. Proper pronunciation, modulation, and use of pauses are important for clear communication.
Classification of singularity
This document discusses power series and the classification of singularities. It defines power series as an infinite series involving terms of the form (x - x0)k. Singular points are points where a function is not analytic, meaning it does not have a convergent Taylor series. Singular points are classified as regular singular points if (x - x0)P(x) and (x - x0)2Q(x) are analytic, or irregular singular points if they are not analytic.
Msm
Solidification is the process where a liquid turns into a solid when its temperature is lowered below the freezing point. Nucleation is the first step of solidification, where tiny stable nuclei are created in the liquid metal. There are two types of nucleation: homogeneous nucleation which occurs from clustering of atoms at high undercooling, and heterogeneous nucleation which occurs more commonly on surfaces like the mold walls or impurities. Once a nucleus reaches the critical size, growth will occur as more atoms attach in an exothermic process releasing heat, which must be removed for solidification to continue. Understanding nucleation and solidification is important for industrial casting and welding processes where metal melting and resolidification occurs.
Various work holding devices
This document summarizes various types of work holding devices used in lathe machines, including four jaw independent chucks, three jaw universal chucks, combination chucks, magnetic chucks, collet chucks, drill chucks, lathe centers, steady rests, follower rests, mandrels, lathe dogs, and lathe face plates. It provides brief descriptions of each device, highlighting their main features and purposes.
Newton's forward difference
This document provides Newton's formula for forward difference interpolation and an example of using it to find the value of tan(0.12).
- Newton's formula uses forward difference interpolation to find the value of a polynomial of degree n that fits a set of (n+1) equally spaced (x,y) points.
- The coefficients of the polynomial are determined using forward differences of the y-values.
- In the example, the value of tan(0.12) is found by applying Newton's formula to a table of tan(x) values from 0.10 to 0.30 using forward differences up to degree 4.
Metal melting furnaces
The document discusses different types of metal melting furnaces used in metal casting. It describes Cupola Furnaces, Electric Arc Furnaces, Induction Furnaces, and Metal Pot Furnaces. Cupola Furnaces use layers of metal, coke and limestone fed into the top to melt iron and ferrous alloys through combustion. Electric Arc Furnaces use carbon electrodes to generate arcs and melt metal through heat. Induction Furnaces use electromagnetic induction to rapidly heat and melt metals. Metal Pot Furnaces are used for low melting point alloys like aluminum and are heated by gas or oil without direct contact between flames and metal.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdf
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days
