Vaastu –
The science of a vibrant house
Everybody in this world want to lead a happy, peaceful
and comfortable life. Normally a person may spend about ten to twelve hours
outside in connection with his office work, business or other activities. The remaining
time, he will be inside the house with his family members. He may like to have
a healthy and peaceful environment in
his house.
A house should not be a dead structure with four walls
and a roof over it. It must be a place emanating healthy vibrations. For this,
according to vasstu, the layout and
orientation of the house has a major role to play.
The word
'Vaastu' in Sanskrit means
'dwelling'. Vaastu Shastra is originated in India. It deals with architecture and governs town planning and designing of man-made
structures. It aims in providing guidelines for proper
construction so that the inhabitants can lead a comfortable life in
consonance with the cosmic energies. It is considered that this science was
developed during the period of 6000 BC and 3000 BC. According to Vasstu Shastras five elements - Earth, Fire, Water, Air
and Sky influence our houses. It also emphasizes that the house should be so constructed that positive
forces override the negative forces. Some people of the modern day are of the
opinion that in the present context of living in muti storey buildings with air conditioners
and septic tanks in the compound itself, is it possible to construct a building
completely as per the vasasthu guide
lines? No doubt one has to adapt it as per the present situations without
deviating much from the original philosophy..

The
science of vaasthu was developed
about 5000 years ago. It is not possible to follow completely the principles as
suggested at that time. Due to urbanization, people are compelled to move to
flats in multistory buildings. But still the principles can be followed to the
extent possible. They are:
1. Open
space must be left all around the building.
2. The site should be a good square or a rectangle if possible..
3. An open
well or a bore well should essentially be there in the North East..
4. Kitchens are preferred in the South East or North West.
5. It is not advisable to have balconies in the South and West.
6. Stair cases should be avoided in the North East.
7. Main entrance into the building should be from East, North,
North East, West or North West.
8. There should not be any big tree in north or east of the plot.
9. Rainwater should flow from south to north and west to east.
10 Walls should not be painted in black, sky blue or red colours.
11. It is advisable to keep the
door of bathroom closed at all times.
12. When the television is
switched off, the screen may be covered with a clean cloth.
13.No mirror should be fixed in
the bed room facing bed.
Vaasthu Tips for a healthy and happy Family Life
Tips for Peace:

SLOPE STABILITY
Key words slope stability , causes, shearing strength
Introduction
Land
slides are the downward and outward movements of materials on the slope. The reason for this is
the lack of required shear strength. The slope materials may be composed of
natural rock and soil, artificial fills. Slides can occur in natural slopes as
well as man- made structures and embankments.
Great
care should be taken in the selection of good construction material and also
suitable construction methods to avoid sliding of slopes.
Causes of slope failures
The
causes of slope failures may be external or internal.
External:
Steepening of the slopes, depositing of material along the edge of the slopes
and earthquakes.
Internal:
Decrease in shearing resistance due to excess pore water pressure, leaching of
salts, softening and breakage of cementation bonds.
The
other activities which may provoke land slides are: Rapid draw down, seepage of
water, erosion, heavy rainfall, excavation at the toe of the slope, excavation
at the head of the slope, blocking of the drainage.
Basic concepts of stability analysis
All
sloping surfaces are subjected to shearing stresses .The shear available should overcome the developed stresses. If
the shearing stresses are more, then a surface of rupture will be formed at the
verge of failure.
1.
Finding the most severely stressed internal surface and the connected shearing
stress along the surface Finding the
shearing strength along the surface
Instead
of resorting to rigorous mathematical analysis, a reasonable shape of failure
is assumed and then the stability of the soil above the assumed surface is
analysed.
Rate of land movement
The
movements associated with land slides can be grouped under four heads.
- Creep, pre-failure movements, movements
during slides, post failure movements.
Creep
may range from 1 to few millimeters per
year. Heavily over consolidated clays experience post failure movements, the
speed of movements ranging from 0 to 6 m per year.
Importance of the Factor of Safety on
slope stability analysis.
It
is a measure of limiting the stress or strain so as to ensure the safety of the
structure. As such, the working stress in any earth structure is much less than
the shear strength of the soil.
The
Factor of Safety may be defined as the ratio of shearing resistance available
(τf ) along a slip surface to the total mobilized or developed shearing
stress.( Ï„ ).
F=
τf / τ
Both
cohesion and friction contribute to the shearing strength

Kuttan Nair forgot his keys ( a micro storey)
Kuttan Nair was returning from his daughter’s
house. The village road was almost empty.
The sun was approaching the
western horizon. A group of cranes flew over the green fields. In the nearby play
ground children were playing football.
Suddenly he remembered that he had forgotten to take his house keys. When he came
yesterday to his daughter’s house, he had kept it over the
table in the sitting room. He turned back and started walking towards his
daughter’s house.
******************************
Kuttan (Ku) Nair was staying in a remote village in Kerala. The
house was constructed by his ancestors years
back. It was
made out of mud. Even in summer,
the inside of the house was quite cool His wife Sulochana (Su) and daughter Parvati (Pa) were with him. There were a large number of coconut,
arecanut, jack fruit, teakwood trees in the house compound. Also he
was nurturing a quite big vegetable garden. The surplus vegetables
were sold in the nearby market. In his
house compound there was a small pond.
Water was drawn from the pond. In front of the house there was a small stream.
Beyond the stream was paddy fields.
Altogether it gave really a
panoramic view.
Ku’ spent most of his time in the
field and garden. He was able to raise
sufficient money from the sale of the agricultural products. There was a
Krishna temple near his house. Pa’ and
Su’ used to go to the temple regularly in the evening. Once in a year in the
month of October there used to be a pooram festival in the temple. The
celebration lasted for three days. Various cultural programs like Ottan thullal , Dance, Chakyar kooth etc were being enacted during this period.
Su’
spent her spare time in reading books. There was a small library near to her house. She used to get books
from there. She was interested in painting also. She taught few student painting.
Pa’ was studying in a nearby college.
She took part in various cultural activities and won many prizes. She also acted as the Editor of the college magazine.
After graduation, she joined as a teacher in the nearby school. At the same time she continued with her cultural activities. By the time her parents started searching a suitable boy for her marriage. They gave advertisement in a local news paper. Pa’ told her parents that she was not interested in marrying a boy working in the middle east. She wanted the boy to be near to her place. After lot of searches, they could identify a boy from the neighboring town. He was working in the state government revenue department.
The marriage was solemnized in the
traditional style. Only close relatives were invited for the marriage After marriage, Pa’ shifted to her husband’s house. She was
happy with her in laws. Father- in- law was a retired government servant. The
school was very near to her house. She could come to the house for lunch also.
It was a Sunday evening. Pa’ was seeing a cinema in the TV. Mother in law was in the
kitchen preparing evening tea. At that time
she got a whatsup message. After reading the message, she started crying loudly. Mother in law came running from the
kitchen enquiring about the reason of the cry. Pa’ was not in a state to talk.
Mother- in- law sprinkle some water on
her face. Then she murmered that her
mother was no more.
Pa’ along with her husband
immediately rushed to her house. Almost all the neighbors were
there. Her immediate neighbor started
consoling her. She paid respect to her departed mother and sat near the dead
body. She could not imagine that her mother would meet such an untimely death. She
was told that mother was watering the kitchen garden. Suddenly she felt some
uneasiness and fell down. She was immediately taken to the near by
hospital but was declared as brought dead. After the death -
ceremonies she returned to her
husband’s house. She requested her
father to come and stay with her. But he did not agree. He told hat he has to
look after his paddy fields and vegetable garden. But he agreed to come to her house in the week
end.
*****************************
Ku' walked a bit fast. It was getting dark.
Children in the nearby houses started chanting prayers slightly in a louder voice. He opened
the gate of her daughter’s house. Walked towards the portico of the house. He was about to
knock on the door. At that time, he heard a conversation in a
very low tone between Pa’ and her
husband.
“I don’t
think the old man will die in the near future.”
“He is keeping good health now also.”
‘When he
dies, I want to sell
the property and purchase
a new flat in
the town.”
“That will be
nice. I am completely fed up with this
village life.”
Ku’ could
not believe his ears. He was till now thinking that his
daughter was not so greedy and was loving her father very much.
Ku’ collected the keys. He could not tell any thing to Pa’. He came out of the house and started
walking to his house. Old memories cropped up in his mind.
He could not control his sorrow. Tears rolled down from his eyes.

Erosion control using Geo Synthetics
Erosion Control using Geo synthetics
Erosion of soil takes place due to the action of flowing water, rain water or wind. The soil particles then get displaced which in turn creates various engineering and environmental problems. It is therefore very essential to prevent soil erosion. There are different methods to arrest the erosion. One of the effective and economical methods is the use of geosynthetic mats for erosion control.
Introduction
Soil erosion takes place when the shear force generated due to the external agencies such as wind and flowing water exceeds the shearing resistance of the soil particles. To control soil erosion, the shear resistance has to be increased.
Due to erosion, the banks of rivers may cut into the natural ground, road/ railway embankments may collapse leading to serious catastrophes. In case of agricultural soils, the top layer of soil may get depleted and may lead to the loss of fertile soil. It is reported that the soil is swept and washed faster than natural replenishment to the tune of 10 times in USA and 30 to 40 times faster in China and India.
Erosion can be controlled by different methods as natural vegetation, turfing, rip-rap, stone pitching, mats and gabions. But for the last fifty years, geo synthetic materials are being used in large quantities.
Characteristics of Soil Erosion
The main factors affecting erosion are intensity of rain, quantity of rain, duration, slope of the ground and soil permeability.
The types of erosion are - splash, sheet, shore line and rill & gully.
The processes involved in erosion are - detachment, transportation and deposition.
Geo synthetics
Geo means earth or soil and synthetics means man-made. Geo synthetics are made from petrochemical based polymers (plastics) which are biologically inert and will not decompose from bacterial or fungi actions. These are porous fibers manufactured from synthetic materials such as polypropylene, polyester, polyethylene, nylon, polyvinyl chloride and different mixes of these items. They are available in different thicknesses and widths in rolls of various lengths. These fabrics are durable and strong and can with stand hostile soil environment.
These geo synthetic mats are placed on or in the soil to improve slope stability of embankments, hill sides, and river / stream banks. Different geo synthetic materials are geo- textiles, geo- grids, geo- cells, geo- membranes and erosion control materials.
Method of Installation
- Level and compact the area after removing vegetation, debris, stones and other discarded materials.
- Lay the mat and anchor it at the toe of slope properly.
- Construct gabions at the slope benches
Advantages of Geosynthetic Mats
The main advantages of geo synthetic mats are:
Easy and quick installation, economical, environmental friendly, maximum root anchorage, helps in the growth of vegetation and reduces water and wind velocities.
Conclusions
Erosion is a natural phenomenon and can’t be avoided altogether. But its effects can be reduced by taking suitable methods. One such effective and economical method is the use of geo synthetics for the control of erosion.

Happy and Joyful Life
Happy And Joyful life
Tags: Joyful life , happiness, food, shelter , clothing
Everybody in this world want to lead a healthy and happy life. But is it possible? It is difficult to quantify the degree of happiness. Happiness is a state of mind and depends on the attitude of the person concerned.
The basic requirements of a human being are food, shelter and clothing. One can have a meal of a small quantity of cereal while another can have a five star meal; one can have a small one room hut for self and family while another may have a multi storey house in a large estate; while one can have a single piece cheap dress while anther can have a gold laced costly three piece suit. In addition to the basic amenities, one should have good physical and mental health . Then only one should be able to enjoy life to its full extent.
But what is the state of most of the people of this present day world. From a small baby to a grownup youth to a senior citizen, almost all are under some sort of pressure due to the mental agony ,worry and tension. It can be on the personal account, official account or on social account.
Is there a remedy for all these problems? Yes, it is there; but one has to find the solutions himself and practice accordingly. If one can control his emotions, his anger, resentment and greediness and then have a positive outlook towards life, one will be able to lead a happy and joyful life.

Problems of old age
Problems of old age
Tags:
ageing, life style, diseases, free radicals, antioxidants
Each and everybody in this world have to pass through different stages in their life time. The different stages are - childhood , adolescence , adulthood and old age In the old age , problems are manifold . They can be grouped as follows - Physical ,Psychological . Financial , Family related. In the advanced age the old are more prone to face various accidents. Their eye sight may get impaired, may be difficulty in hearing. various life style diseases like diabetes, blood pressure, cholesterol , memory loss (dimentia) etc . Elderly population in India is 138 million in 20121.
As discussed, old age is an inevitable stage in everybody's life. But the irony is that all want to remain, youthful always. As days pass, one gets older and changes take place both
physically and mentally. Ageing is a natural process which affects the whole
body. Since it is a natural process, it can’t be stopped altogether but can
only be slowed down to a certain extent.
The rate of ageing will speed up on account of lack of exercise, improper food,
lack of sleep and mental worry. By correcting the lifestyle, the rate of ageing
can be slowed down considerably.
In old age skin loses its elasticity, eye sight gets impaired, muscles weaken, black hair turns to white, teeth get decayed and
various other diseases increase. Heredity plays a very important role in
ageing. Highly corrosive oxidising elements called free radicals attack our
body. The main causes of free radicals are air pollution, strong sun light,
cigarette smoking and absence of nutritious food. As a remedial step, antioxidants should be taken
which break down the free radicals. The main anti oxidants are vitamins - A, C
and E and the mineral selenium.
Summarising, the main effects of ageing are:
Increased chances for heart attack, arthritis , cancer
Impaired hearing, loss of teeth, cataract etc
Black hair turning white
Poor sleep, irritability
Bones turn more brittle due to loss of calcium
As mentioned earlier, ageing is a natural process
which can’t be stopped but can be only slowed down
to a certain extent by changing the life style.

Mental Tension and Worry- The disease of the modern world
key words - tension worry calm peace
The other
day Sindhu, a B Tech final year student told me that she forgot to write her roll number in the
answer book of the examination.
I asked her
why?
She answered
that she was under mental tension and as
such forgot to write her roll number.
People of
all ages starting from a kindergarten student to a senior citizen from all
strata of the society - house wife,
engineer, doctor, politician etc all are
under tension in one way or the other.
But is it
possible to avoid this mental tension?
Swami
Vivekananda says “The calmer we are, the less disturbed our nerves, the more
shall we learn, the better our work be”. But seldom we can find a person leading a calm and peaceful life. Now
a days nervous tension has become a regular phenomenon. Some of the stress
induced diseases are heart attack and high blood pressure. The degree of
tension may differ depending on the place and situation. Some may be undergoing
tension in his office , others may suffer in their home and some others may be
undergoing both in their office and home as well.
Stress can’t
be completely avoided but it can be controlled to a certain extent. Stress can
be positive as well as negative. It is the negative stress which causes nerves
tension, anger, jealousy and other problems.
If we are
able to remain calm under any provocation, to a large extent tension can be
minimized. For this we should have strong will power and faith in our self. We
should learn to live in the present forgetting the past. By practicing
meditation, to a large extent, tranquility can be maintained and also regular
practice will help in removing negative feelings.
