Suara dan bau mu mengelilingi area rumahku..
Tak seperti biasa aku menghirup udara pagi bercampur bau mu yang khas
Embek…Embek..
Begitulah suara mu..
Betapa kasihannya engkau…
Diikat leher mu hingga sekuat kuatnya berharap agar kau tidak kabur
Mowwww…Mowww..
Tapi engkau tak sendiri..
Banyak teman senasib sepenanggungan menemanimu..
Bahkan teman besar mu yang ukuranmu 5 x kali ukuran mu juga menemanimu..
Ikhlaskan duhai engkau..
Karena engkau merupakan pijakan kami menuju Surga..
Aku tersadar..
Akan kutunaikan salah satu perintahNya..
Idul Adha..

Why Eiffel Tower was Built
If we talk about the Wonders of the World buildings, then we will see Eiffel Tower as one of them. However many of us do not know the tower’s past history on why it was build. Everything has the reasonable background, especially for the tower which is to be one of the most recognized buildings in the world.
Primarily, the Eiffel Tower was built for the World Exhibition. It was called Paris Exposition in 1889. The exhibition was organized to celebrate the 100th anniversary of the French Revolution. The purpose of building Eiffel Tower in such structure was to show to the world France’s advancement of technology and beauty. The Eiffel Tower was designed by Gustave Eiffel. It seemed that then the name of the tower was derived from the designer’s last name, “Eiffel”
Another reason on why the tower was built was for scientific progress. Although few realized it, the Eiffel Tower would become the prominent structure in terms of science and technology. Many experiment with temperature, pressure and pendulums were performed atop the unique famous building. Additionally the Eiffel Tower was used for radio transmission tower. Many experiments were conducted atop the Eiffel Tower for radio transmission advancement. Once the Eiffel Tower was proposed to be demolished but it was spared because the tower had the promising future as a radio tower.

Venus fly trap
The United States of America is where the Venus’s fly trap has its origins. The Venus’s fly trap is a unique plant. It belongs to a group of plants called ‘carnivorous plants’. These plants feed on insect. The Venus’s fly trap has a special mechanism by which it traps its prey. This is how it works.
At the end of each leaf – which grows from the base of a long, flowering stalk – there is a trap. The trap is made up of two lobes and is covered with short, reddish hairs which are sensitive. There are teeth like structures around the edge of the lobes.
The trap contains nectar which attracts insect. When an insect comes in contact with the nectar, the trap snaps shut. There are certain digestive juice inside the trap which digest the insect. It takes about ten days for a trapped insect to be digested. We can tell when this digestion is complete, for then the walls automatically open to wait for another victim.
There are two hundred species of carnivorous plants. Another kind of these well- known species is the pitcher plant. What differentiates this plant from the Venus’s fly trap is the shape; the mechanism to catch insects is the same in both plants.
The pitcher plants which cling to other plants by means of tendrils. At one end of the tendril, there is a pitcher –shaped vessel with an open lid. The mouth and the lid of the pitcher contain glands which produce nectar to attract insect. When an insect settles on the nectar, the lid of the pitcher shuts, trapping its victim. The digestive juices inside the pitcher then begin to work.

The effects of acid soil
Soils with a pH of less than 7.0 are acid. The lower the pH, the more acid the soil. When soil pH falls below 5.5, plant growth is affected. Crop yields decrease, reducing productivity
Soils provide water and nutrients for plant growth and development. Essential plant nutrients include phosphorus, nitrogen, potassium and sulfur. Plants require other elements such as molybdenum, in smaller quantities. Some elements eg aluminium and manganese, are toxic to plants.
Nutrients become available to plants when they are dissolved in water. Plants are able to take up phosphate, nitrate, potassium and sulfate ions in solution.
The solubility of nitients changes with pH. In acid soils (low pH), molybdenum becomes less soluble and aluminium becomes more soluble. Therefore, plant growth may be affected by either a deficiency of molybdenum or too much aluminium.
Both crop and pasture plants are affected by acid soils. there may be a range of symptoms. Crops and pastures may be poorly established resulting in patchy and uneven growth. Plant leaves may go yellow and die at the tips. The root system of the plant may be stunted. Crops may yield less.
Plants vary in their sensitivity to low pH. Canola and lucerne are very sensitive to acid soils so do not grow well. Lupins and triticale are tolerant to soils of low pH so they still perform well.
Land can become unproductive if acid soil is left untreated. Incorporating lime into the soil raises the pH. Therefore, liming soil can reverse the effects of acid soil on plants and return a paddock to productivity.

How Roman Roads were Built
The system of roads for mobility has been begun early decades. It was started since the Roman Empire conquered the world. The roads in Roman era were known as the best construction.
The Romans built roads are for the purpose of mobility, especially for the army. Having the best road, the army could march from one place to another. They built the roads as straight as possible, so that the army could take the shortest route.
It is interesting to know how the roads were built, which some of them are still in use today. First, the Romans builders would clear the ground of rocks and trees. Then they dug a trench where the road was to go and filled it with big stones. Next, they put in big stones, pebbles, cement and sand which they packed down to make a firm base. After that, they added another layer of cement mixed with broken tiles. On top of that rough construction, then they put paving stones to make the flat surface. These stones were cut so that they fitted together tightly. As the finishing touch, kerb stones were put at each sides of the road to hold in the paving stones. It was also used to make a channel for the water to run away.
