BP’s top kill effort fails to plug Gulf oil leak

BP’s top kill effort fails to plug Gulf oil leak

The most ambitious bid yet to stop the worst oil spill in U.S. history ended in failure Saturday after BP was unable to overwhelm the gusher of crude with heavy fluids and junk. President Obama called the setback “as enraging as it is heartbreaking.”

The oil giant immediately began readying its next attempted fix, using robot submarines to cut the pipe that’s gushing the oil and cap it with funnel-like device, but the only guaranteed solution remains more than two months away.

The company determined the “top kill” had failed after it spent three days pumping heavy drilling mud into the crippled well 5,000 feet underwater. It’s the latest in a series of failures to stop the crude that’s fouling marshland and beaches, as estimates of how much oil is leaking grow more dire.

Mother

The world is full of sons and daughters like you and me
I had a marvelous mother, who loved me,
Sacrificed for me and helped me in every way possible.
In all of my growing up from childhood through
School and eventually marriage,
My mother was always at my side.
And when I needed help with my little ones,
She was there for me.
A few years ago, we buried this wonderful woman.
Can you imagine how I felt when I returned home and
Found poem in her drawer written by my mom.
The time is now
If you are ever going to love
Love me now while I can know
The sweet and tender feelings
Which from true affection flow
Love me now while I am living
Do not wait until I am gone
And then have it chiselled in marble
Sweet words on ice-cold stone
If you have tender thoughts of me
Please let me know now
If you wait until I am sleeping
There will be death between us
And I will not hear you then
So if you love me, even a little bit
Let me know while I am living
So that I can treasure it
Now she is gone and I am sick with guilt
Because I never told her what she meant to me.
Worse yet, I did not treat her as she deserved to be treated.
I found time for everyone and everything else
But I never made time for her.
It would have been easy to drop in for a cup of tea
And a hug but my friends came first.
Would any of them have done for me what my mother did,
I know the answer.
When I called mom on the phone,
I was always in a hurry.
I feel ashamed when I think of the times I cut her off
, The times I retorted back to her , The times I glared at her in a angry mood when she wanted to correct me and guide me through the correct path.
I remember too, the times I could have included
her in a trip out and did not.

Our children loved Grandma from the times they were babies.
They often turn to her for comfort and advice.
She understood them.
I realise now that I was too critical,
Too short-tempered, too stingy with praise.
Grandma gave them unconditional love.
The world is filled with sons, daughters and a child like me.
I hope they see themselves in this letter and realise from it
.

If this has touched you, please pass it on to all the sons and
Daughters who have to praise their mom for everything they are today.

Review: Earthquake Resistant Building Design

Designing Earthquake Resistant Buildings :

 

Tips and Tricks

Earthquakes are a dangerous phenomena. People are vulnerable to the destructive power of earthquakes. Earthquakes have unleashed their destructive power on humans time and time again. But today, with the advancement of construction technology, man has learnt to protect himseld from earthquakes.

What is an Earthquake?

An earthquake is a sudden, rapid shaking of the Earth caused by the breaking and shifting of rock beneath the Earth’s surface.

Ground shaking from earthquakes can collapse buildings and bridges; disrupt gas, electric, and phone services; and sometimes trigger landslides, avalanches, flash floods, fires, and huge, destructive ocean waves (tsunamis). Buildings with foundations resting on unconsolidated landfill and other unstable soil, and trailers and homes not tied to their foundations are at risk because they can be shaken off their mountings during an earthquake. When an earthquake occurs in a populated area, it may cause deaths and injuries and extensive property damage.

It is for this reason that it is often said,

“Earthquake don’t kill people, buildings do.”

Earthquake Resistant Building Design Philosophy
a) Under minor but frequent shaking, the main members of the buildings that carry vertical and horizontal forces should not be damaged; however buildings parts that do not carry load may sustain repairable damage.

b) Under moderate but occasional shaking, the main members may sustain repairable damage, while the other parts that do not carry load may sustain repairable damage.

c) Under strong but rare shaking, the main members may sustain severe damage, but the building should not collapse.

Protection from Earthquakes

There are various new techniques which help in reducing the impact of earthquake forces on buildings. Most of these techniques are expensive to implement.

Here is a list of Earthquake Resistant Techniques…

1. Base Isolation for Earthquake Resistance

The concept of base isolation is explained through an example building resting on frictionless rollers. When the ground shakes, the rollers freely roll, but the building above does not move. Thus, no force is transferred to the building due to the shaking of the ground; simply, the building does not experience the earthquake. Now, if the same building is rested on the flexible pads that offer resistance against lateral movements (fig 1b), then some effect of the ground shaking will be transferred to the building above. If the flexible pads are properly chosen, the forces induced by ground shaking can be a few times smaller than that experienced by the building built directly on ground, namely a fixed base building. The flexible pads are called base-isolators, whereas the structures protected by means of these devices are called base-isolated buildings.

2. Energy Dissipation Devices for Earthquake Resistance

Another approach for controlling seismic damage in buildings and improving their seismic performance is by installing Seismic Dampers in place of structural elements, such as diagonal braces. These dampers act like the hydraulic shock absorbers in cars – much of the sudden jerks are absorbed in the hydraulic fluids and only little is transmitted above to the chassis of the car. When seismic energy is transmitted through them, dampers absorb part of it, and thus damp the motion of the building.

3. Active Control Devices for Earthquake Resistance

The system consists of three basic elements:

a. Sensors to measure external excitation and/or structural response.

b. Computer hardware and software to compute control forces on the basis of observed excitation and/or structural response.

 

c. Actuators to provide the necessary control forces.

Thus in active system has to necessarily have an external energy input to drive the actuators. On the other hand passive systems do not required external energy and their efficiency depends on tunings of system to expected excitation and structural behavior. As a result, the passive systems are effective only for the modes of the vibrations for which these are tuned. Thus the advantage of an active system lies in its much wider range of applicability since the control forces are worked out on the basis of actual excitation and structural behavior. In the active system when only external excitation is measured system is said to be in open-looped. However when the structural response is used as input, the system is in closed loop control.

These techniques have been successfully employed in many projects across the world. They are most widely used in Japan. These techniques are also being used in earthquake prone areas of California, Indonesia and other such places.
