To get happiness!!!!!

God created same world for everyone. I am 23 year old and cant able to digest why one is rich and another is poor. The reason may be the rich one struggled in past to become rich or he/she had born in rich home. So it’s not question about rich people, because they got all resource to become better or they are already rich. It’s all about poor peoples who don’t have enough resources to come over it and do contributions into the betterment of the world and they move towards terrorism, etc. Invest 10% of your income in particular person development for betterment.

Resources (money, oil, lands, water) never belong to a particular country or person, we are just guardian of these resources and have responsibility to look after its proper distribution and use. Every person in this universe has equal rights to these resources.  So help everyone to get their rights.

 
In this world, there is no comparison of happiness to seeing smile on faces. Help as much as people in this world, so the smile starts spreading like virus.

Twin-Wing Tsunami Barrier

On December 26, 2004 a major earthquake with a magnitude between 9.1 and 9.3 on the Richter scale occurred off the West Coast of Sumatra, Indonesia. This earthquake generated a devastating tsunami. Several countries suffered from the gigantic tsunami, many people died and many more lost their properties. The tsunami struck the West Coast of Peninsular Malaysia and killed 68 people and destroyed many properties. The Island of Penang was one of the places that suffered from the disaster. Fifty seven people died in this area when most of them were enjoying their time on the beach. Many home appliances, several boats and fishing equipments were also destroyed in the area. In order to prevent similar damages from a possible recurring tsunami event “TWIN-WING TSUNAMI BARRIER’’ has been used to design an offshore barrier to dissipate the tsunami wave energy in this study. The opportunity to develop an innovative barrier to break down the mass of the wave, to neutralize its energy and prevent them from reaching economically strategic coastal areas became overwhelming. 

Use of Rubber Particles from Recycled Tires as ConcreteAggregate for Engineering Applications

Investigations and research into the recent use of rubber particles in concrete has been in practice. However, information on the rubber particle sizes or their distributions within concrete which may also influence the concrete properties is still limited. In practice, three groups of singly-sized rubber particle samples (3 mm, 0.5 mm and 0.3 mm) and one sample of continuous size grading (prepared by blending the three singly-sized samples to form the same particle distribution curve of sand) were used to replace 20% of the natural fine aggregate by volume. The reference concrete containing 100% sand was also prepared to compare its properties with those of the samples in terms of workability, fresh density, compressive strength, tensile splitting strength, flexural strength and water permeability. The experimental results demonstrated that the rubber particle size affects the concrete's workability and water permeability to a greater extent than the fresh density and strength. Concrete with rubber particles of larger size tends to have a higher workability and fresh density than that with smaller particle sizes. However, the rubber aggregates with smaller or continuously graded particle sizes are shown to have higher strengths and lower water permeability.

Thirsty Concrete Pavement!!!

Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge.

Pervious concrete is made using large aggregates with little to no fine aggregates. The concrete paste then coats the aggregates and allows water to pass through the concrete slab. Pervious concrete is traditionally used in parking areas, areas with light traffic, residential street, pedestrian walkways, and greenhouses. It is an important application for sustainable construction and is one of many low impact development techniques used by builders to protect water quality.
