It outlines six major effects of climate change like more frequent droughts and storms, and heat waves. Five causes of climate change are then given as increased fossil fuel use, deforestation, and cutting down forests. Examples of climate change impacts like rising temperatures and more severe tropical storms are provided. The document concludes with some solutions to climate change like saving energy, using less carbon intensive transportation, and eating more plants.
This document discusses air pollution and the Clean Air Act. It notes that the Clean Air Act was established in 1963 to study and clean up air pollution, with the EPA taking the lead role in 1970. The 1990 revisions expanded EPA authority and emphasized more cost-effective regulation. As a result of these laws, the six main air pollutants have decreased over 50% since 1970. The document urges readers to help reduce pollution through energy conservation and efficient transportation. It also explains thermal inversions, how they trap pollutants near the ground, and demonstrates this phenomenon with an experiment.
Global environmental issues include global warming and the greenhouse effect, climate change, acid rain, ozone layer depletion, and carbon footprint. These issues threaten the planet through rising temperatures, changing weather patterns, pollution of land and water, and damage to the atmosphere. Addressing them requires initiatives like cleaner development mechanisms to reduce emissions and environmental impact.
This document discusses air pollution, including its definition, composition of air, structure of the atmosphere, classification of air pollutants, sources of common air pollutants, and effects of common air pollutants. It defines air pollution and explains that the atmosphere consists of five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere - each with varying temperature and density properties. It also classifies air pollutants according to their origin as primary or secondary pollutants and state of matter as gaseous or particulate, and lists some common sources and health effects of major air pollutants.
The document discusses particulate matter (PM) air pollution, including what PM is, its health risks like premature death and respiratory disease, how it is regulated, where it originates from both natural and human sources, and the extensive research that has been done to understand its effects through epidemiological studies and the setting of future research priorities.
This document outlines the teaching scheme and content for an Environmental Science course taught by Dr. Ujas Pandya. The course covers topics such as introduction to the environment, different types of pollution, global environmental issues, green buildings and smart cities, and the concept of reduce, reuse, recycle. It will include 2 hours of lectures and 2 hours of tutorials per week. Key topics include the components of the environment, environmental pollution and its causes, environmental degradation due to human activities, and the importance of environmental education.
Surveying is the science of determining the positions of points on or near the earth's surface. It involves decision making, fieldwork, data processing, mapping, and stakeout. The primary objectives of surveying are to prepare plans for estates, buildings, infrastructure, and to measure areas. Plane surveying considers the earth's surface flat over small areas, while geodetic surveying accounts for curvature over large areas. Distance is typically measured using tapes or chains, and errors are corrected for tape length and temperature.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
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

efflorescence.
24. •Hollow bricks are mainly used in the
construction of houses.
•The raw material used in the
construction of such bricks are basically
fly ash, cement, lime, gypsum, stone dust
etc.
•These hollow bricks are lighter in weight
than the normal bricks which made it
possible to place.
25. Hollow bricks are lighter and easier
to handle, and have thermal
properties different from solid bricks.
The cut bricks are hardened by
drying for 20 to 40 hours at 50 to 150
°C before being fired.
The heat for drying is often waste
heat from the kiln.
26. QUALITIES OF A GOOD BRICKS
Bricks are manufactured from naturally
available material clay.
Bricks are light in weight compared to
stones.
They are durable .
They are low cost material.
They possess good strength.

27. The shape of an ideal brick is rectangular.
It has sharp edges and corners.
The surface is regular and even.
Good bricks are of standard size:19x9x9cm
The most common colour of well burnt
brick is red .
Dark red colour of brick is indicator of over
burning and yellow colour of brick is the
indicator of under burning.
28. A single brick will weight 3.2-
3.5 kg.
Density varies from 1600– 1900
kg/m3.
Compressive strength of brick
may vary from 35 - 200kg/cm2.
Good brick shall possess a
shearing strength of 50-70
kg/cm2.
29. Water absorption value of good quality
bricks shall not be more than 20%-25%.
Higher absorption means higher porosity.
Higher absorption will lead to frost action
and efflorescence.
Durability of bricks depends on absorption
value, frost resistance and efflorescence.
Due to efflorescence brick surface covered
with white or grey patches salts.
Higher absorption results in deeper
penetration of water which becomes a
source of dampness.
30. Heat and sound conductivity
varies with their density and
porosity.
Very dense and heavy bricks
conduct heat and sound at a great
rate.

57. WHAT IS TIMBER?
Timber is a material which can be used for
building or carpentry and is derived from
trees. It is organic and renewable and can be
used in a wide range of applications.
In order to make best use of timber in
environmental buildings we must
understand how timber is produced and how
its natural properties effect it as a building
material.
59. Properties of timber
It has low heat conductivity.
It has small bulk density.
It is relatively high strength.
It is susceptible to decay.
It is susceptible to flame.
61. Requirement of Good Timber
• Annual ring of the section must be close to each
other.
• It should be dark uniform colour.
• It should be dense.
• It should be workable, good machinability.
• It should have uniform texture.
• When it is struck it should produce sonorous sound.
• The rays should be compact.
• It should be free from defects like dead knots,
rupture,etc.
• There should not decay of timber due to fungi and
insects like white ants and termites.
• It should be free from crakes, splits etc.
62. Seasoning
Seasoning is the reduction of
the moisture content of wood.
Seasoning is also the controlled
drying out of timber.
About 50% of the weight of
newly-felled tree is water
63. Seasoning
Reasons for Seasoning:
Seasoning helps to save the wood from
splitting.
Dry timber (< 20% MC) will not be
attacked by fungi
Dry timber is less likely to be affected by
shrinkage or distortion
After seasoning, timber will be lighter,
harder and stronger.
Seasoning produces timber that is easier to
work with.
64. Types of Seasoning
There are two types of
seasoning are as follows,
I.Natural or air seasoning
II.Artificial or kiln seasoning
65. Natural Seasoning
Advantages of Natural Seasoning
-No expensive equipment required
-Small labour cost
-Not wasteful of energy
Disadvantages of Natural Seasoning
-Slow drying rate
-Large area of space required
-Dependant on the weather
-Rate of seasoning cannot be carefully
controlled
-Only seasons to a MC of 18% - 22%
66. Kiln Seasoning
• The timber is placed in large kilns (ovens) where
temperatures, humidity and drying rates are
controlled
• There are 2 types of kiln:
-Compartment Kiln & Progressive Kiln
67. Compartment Kiln
Timber is stacked similar to that
in natural seasoning only it is on a
trolley which runs on rails.
1. The kiln is closed before steam
jets in the walls, ceiling and floor
release heated steam.
2. The timber is allowed to heat up
but not dry out.
68. Compartment Kiln
3. The relative humidity of the kiln is
reduced (controlled) while the
heat is maintained. (This allows
moisture in the wood to evaporate
gradually)
4. Fans circulate the air around the
kiln.
5. Air vents allow moist wet air out
and fresh air in.
69. Progressive Kiln
The progressive kiln is a
continuous kiln.
The timber goes through the
various stages of drying as it moves
through the kiln on a trolley.
The drying process is the same as
that for the Compartment Kiln.
70. Kiln Seasoning
Advantages of Kiln Seasoning
-Quicker due to higher temperatures, ventilation and air
circulation
-Achieves a lower moisture content
-Provides greater degree of control during the drying
process
-Allows more precise rates of drying
-Allows uniform circulation through the stack
-Control over moisture content and rate of drying can be
achieved
-Artificial defects can be controlled
Disadvantages of Kiln Seasoning
-It is expensive
-Requires supervision by a skilled operator
-Is dependant on energy
71. Sand
Requirements of sand
It should be clean.
It should be well graded.
Maximum permissible clay content is 3 to 4% in
sand.
It should contain sharp, angular grains.
It should not contain salts which attract moisture
from the atmosphere.
72. Types of sand
Natural
natural sand is obtained from pits, river beds and
sea beds.
Artificial
artificial sand is formed by decomposition of
sandstone due to various weathering effects.
73. Uses
Sand is useful in various construction
activities like masonry work, plaster
work, flooring and concrete work.
Sand is used in cement mortar, plan
cement concrete , reinforced cement
concrete and prestressed concrete as
key ingradient in building construction
74. Properties of sand

<4> Prestressed concrete
86. A black or dark brown viscous
material, composed principally of
high molecular weight
hydrocarbons, having adhesive
properties, derived from petroleum
either by natural or refinery
processes and substantially soluble
in carbon disulphide.
87. ORIGIN
Asphalt materials have been utilized
since 3500 B.C. In building and road
construction. Their main uses have
been as adhesives, waterproofing
agents.
These early asphalt materials were
native asphalt. These native asphalts
were found in pools and asphalt lakes.
For example Trinidad and Bermudez
lake deposits (asphalt lake).
89. Demand for paved roads/
construction exceeded the supply
of lake asphalts in late 1800, lead
to use of petroleum asphalts
90. Basic Refining Process
Asphalt is simply the residue left over from
petroleum refining.
Crude oil is heated in a large furnace to about 340°
C (650° F) and partially vaporized. It is then fed
into a distillation tower where the lighter
components vaporize and are drawn off for further
processing.
The residue from this process (the asphalt) is
usually fed into a vacuum distillation unit where
heavier gas oils are drawn off.
