WARISAN



WARISAN - ANAK KECIL MAIN API


Anak kecil main api
Terbakar hatinya yang sepi
Air mata darah bercampur keringat
Bumi dipijak milik orang

Nenek moyang kaya-raya
Tergadai seluruh harta benda
Akibat sengketa sesamalah kita
Cinta lenyap di arus zaman

Indahnya bumi kita ini
Warisan berkurun lamanya
Hasil mengalir ke tangan yang lain
Peribumi merintih sendiri

Masa depan sungguh kelam
Kan lenyap peristiwa semalam
Tertutuplah hati terkunci mati
Maruah peribadi dah hilang

Kini kita cuma tinggal kuasa
Yang akan menentukan bangsa
Bersatulah hati bersama berbakti
Pulih kembali harga diri

Kita sudah tiada masa
Majulah dengan maha perkasa
Janganlah terlalai teruskan usaha
Melayu kan gagah di nusantara

Melayu kan gagah di nusantara
Melayu kan gagah di nusantara

How Jet Engine Works




Picture of Engine with engine parts identified



Fan - The fan is the first component in a turbofan. The large spinning fan sucks in large quantities of air. Most blades of the fan are made of titanium. It then speeds this air up and splits it into two parts. One part continues through the "core" or center of the jet engine, where it is acted upon by the other jet engine components.The second part "bypasses" the core of the
jet engine. It goes through a duct that surrounds the core to the back of the jet engine where it produces much of the force that propels the airplane forward. This cooler air helps to quiet the jet engine as well as adding thrust to the jet engine.

The compressor is the first component in the jet engine core. The compressor is made up of fans with many blades and attached to a shaft. The compressor squeezes the air that enters it into progressively smaller areas, resulting in an increase in the air pressure. This results in an increase in the energy potential of the air. The squashed air is forced into the combustion chamber.


Combustor - In the combustor the air is mixed with fuel and then ignited. There are as many as 20 nozzles to spray fuel into the air stream. The mixture of air and fuel catches fire. This provides a high temperature, high-energy airflow. The fuel burns with the oxygen in the compressed air, producing hot expanding gases. The inside of the combustor is often made of ceramic materials to provide a heat-resistant chamber. The heat can reach 2700°.


Turbine - The high-energy airflow coming out of the combustor goes into the turbine, causing the turbine blades to rotate. The turbines are linked by a shaft to turn the blades in the compressor and to spin the intake fan at the front. This rotation takes some energy from the high-energy flow that is used to drive the fan and the compressor. The gases produced in the combustion chamber move through the turbine and spin its blades. The turbines of the jet spin around thousands of times. They are fixed on shafts which have several sets of ball-bearing in between them.


Nozzle - The nozzle is the exhaust duct of the jet engine. This is the jet engine part which actually produces the thrust for the plane. The energy depleted airflow that passed the turbine, in addition to the colder air that bypassed the engine core, produces a force when exiting the nozzle that acts to propel the engine, and therefore the airplane, forward. The combination of the hot air and cold air are expelled and produce an exhaust, which causes a forward thrust. The nozzle may be preceded by a mixer, which combines the high temperature air coming from the jet engine core with the lower temperature air that was bypassed in the fan. The mixer helps to make the jet engine quieter.

OPERATION OF MARINE DIESEL ENGINE




The MAN B&W 5S50MC 5-cylinder, 2-stroke, low-speed marine diesel engine. This particular engine is found aboard a 29,000 tonne chemical carrier.

Also known as slow-speed, or traditionally oil engines, the largest diesel engines are primarily used to power ships, although there are a few land-based power generation units as well. These extremely large two-stroke engines have power outputs up to approximately 85 MW (114,000 hp), operate in the range from approximately 60 to 200 rpm and are up to 15 m (50 ft) tall, and can weigh over 2,000 short tons (1,800 t). They typically use direct injection running on cheap low-grade heavy fuel, also known as Bunker C fuel, which requires heating in the ship for tanking and before injection due to the fuel's high viscosity. Often, the waste heat recovery steam boilers attached to the engine exhaust ducting generate the needed to heat required for fuel heating. Provided the heavy fuel system is kept warm and circulating, engines can be started and stopped on heavy fuel.

Large and medium marine engines are started with compressed air directly applied to the pistons. Air is applied to cylinders to start the engine forwards or backwards because they are normally directly connected to the propeller without clutch or gearbox, and to provide reverse propulsion either the engine must be run backwards or the ship will utilise an adjustable propeller. At least three cylinders are required with two-stroke engines and at least six cylinders with four-stroke engines to provide torque every 120 degrees.

Companies such as MAN B&W Diesel, (formerly Burmeister & Wain) and Wärtsilä (which acquired Sulzer Diesel) design such large low-speed engines. They are unusually narrow and tall due to the addition of a crosshead bearing. As of 2007, the 14-cylinder Wärtsilä-Sulzer 14RTFLEX96-C turbocharged two-stroke diesel engine built by Wärtsilä licensee Doosan in Korea is the most powerful diesel engine put into service, with a cylinder bore of 960 mm (37.8 in) delivering 114,800 hp (85.6 MW). It was put into service in September 2006, aboard the world's largest container ship Emma Maersk which belongs to the A.P. Moller-Maersk Group. Typical bore size for low-speed engines ranges from approximately 35 to 98 cm (14 to 39 in). As of 2008, all produced low-speed engines with crosshead bearings are in-line configurations; no Vee versions have been produced.

SELAMATKAN ROHINGYA......



******************************************************************

The origin of the term "Rohingya" is disputed. Some Rohingya historians like Khalilur Rahman contend that the term Rohingya is derived from Arabic word 'Rahma' meaning 'mercy'. They trace the term back to a ship wreck in the 8th century CE. According to them, after the Arab ship wrecked near Ramree Island, Arab traders were ordered to be executed by the Arakanese king. Then, they shouted in their language, 'Rahma'. Hence, these people were called 'Raham'. 

Gradually it changed from Raham to Rhohang and finally to Rohingyas However, the claim was disputed by Jahiruddin Ahmed and Nazir Ahmed, former president and Secretary of Arakan Muslim Conference respectively. They argued that ship wreck Muslims are currently called 'Thambu Kya' Muslims, and currently reside along the Arakan sea shore. If the term Rohingya was indeed derived because of that group of Muslims, "Thambu Kyas" would have been the first group to be known as Rohingyas. According to them, Rohingyas were descendants of inhabitants of Ruha in Afghanistan. Another historian, MA Chowdhury argued that among the Muslim populations in Myanmar, the term 'Mrohaung' (Old Arakanese Kingdom) was corrupted to Rohang. And thus inhabitants of the region are called Rohingya.

Burmese historians like Khin Maung Saw have claimed that the term Rohingya has never appeared in history before 1950s.According to another historian, Dr. Maung Maung, there is no such word as Rohingya in 1824 census survey conducted by the British. Historian Aye Chan from Kanda University of International Studies noted that the term Rohingya was created by descendants of Bengalis in 1950s who migrated into Arakan during the Colonial Era. He further argued that the term cannot be found in any historical source in any language before 1950s. However, he stated that it does not mean Muslim communities have not existed in Arakan before 1824.

However, Arakan history expert Dr. Jacques P. Leider points out that the term Rooinga was in fact used in a late 18th century report published by the British Francis Buchanan-Hamilton. In his 1799 article “A Comparative Vocabulary of Some of the Languages Spoken in the Burma Empire,” Buchanan-Hamilton stated: "I shall now add three dialects, spoken in the Burma Empire, but evidently derived from the language of the Hindu nation. The first is that spoken by the Mohammedans, who have long settled in Arakan, and who call themselves Rooinga, or natives of Arakan."Leider also adds that the etymology of the word "does not say anything about politics." He adds that "You use this term for yourself as a political label to give yourself identity in the 20th century. Now how is this term used since the 1950s? It is clear that people who use it want to give this identity to the community that live there.

Early evidence of Bengali Muslim settlements in Arakan date back to the time of King Narameikhla (1430–1434) of Kingdom of Mrauk U. After 24 years of exile in Bengal, he regained control of the Arakanese throne in 1430 with military assistance from the Sultanate of Bengal. The Bengalis who came with him formed their own settlements in the region.Narameikhla ceded some territory to the Sultan of Bengal and recognized his sovereignty over the areas. In recognition of his kingdom's vassal status, the kings of Arakan received Islamic titles and used the use of Bengali Islamic coinage within the kingdom. Narameikhla minted his own coins with Burmese characters on one side and Persian characters on the other. Arakan's vassalage to Bengal was brief. After Sultan Jalaluddin Muhammad Shah's death in 1433, Narameikhla's successors repaid Bengal by occupying Ramu in 1437 and Chittagong in 1459. Arakan would hold Chittagong until 1666.

Even after gaining independence from the Sultans of Bengal, the Arakanese kings continued the custom of maintaining Muslim titles.The Buddhist kings compared themselves to Sultans and fashioned themselves after Mughal rulers. They also continued to employ Muslims in prestigious positions within the royal administration. The Bengali Muslim population increased in the 17th century, as they were employed in a variety of workforces in Arakan. Some of them worked as Bengali, Persian and Arabic scribes in the Arakanese courts, which, despite remaining mostly Buddhist, adopted Islamic fashions from the neighbouring Sultanate of Bengal.The Kamein/Kaman, who are regarded as one of the official ethnic groups of Burma, are descended from these Muslims.
Burmese conquest
British colonial rule

Following the Burmese conquest of Arakan in 1785, as many as 35,000 Arakanese people fled to the neighbouring Chittagong region of British Bengal in 1799 to avoid Burmese persecution and seek protection from British India. The Burmese rulers executed thousands of Arakanese men and deported a considerable portion of the Arakanese population to central Burma, leaving Arakan as a scarcely populated area by the time the British occupied it.According to an article on the "Burma Empire" published by the British Francis Buchanan-Hamilton in 1799, "the Mohammedans, who have long settled in Arakan," "call themselves Rooinga, or natives of Arakan."

Due to Arakan being scarcely populated by the time they occupied it, British policy encouraged Bengali inhabitants from adjacent regions to migrate into fertile valleys of Arakan as agriculturalists. The East India Company extended the Bengal administration to Arakan, thus there was no international boundary between Bengal and Arakan, and no restrictions on migration between the regions. In the early 19th century, thousands of Bengalis from the Chittagong region settled in Arakan seeking work opportunities.In addition, thousands of Rakhine people from Arakan also settled in Bengal.

The British census of 1891 reported 58,255 Muslims in Arakan. By 1911, the Muslim population had increased to 178,647.The waves of migration were primarily due to the requirement of cheap labor from British India to work in the paddy fields. Immigrants from Bengal, mainly from the Chittagong region, "moved en masse into western townships of Arakan". To be sure, Indian immigration to Burma was a nationwide phenomenon, not just restricted to Arakan. Historian Thant Myint-U writes: "At the beginning of the 20th century, Indians were arriving in Burma at the rate of no less than a quarter million per year. The numbers rose steadily until the peak year of 1927, immigration reached 480,000 people, with Rangoon exceeding New York City as the greatest immigration port in the world. This was out of a total population of only 13 million; it was equivalent to the United Kingdom today taking 2 million people a year." By then, in most of the largest cities in Burma, Rangoon (Yangon), Akyab (Sittwe), Bassein (Pathein), Moulmein, the Indian immigrants formed a majority of the population. The Burmese under the British rule felt helpless, and reacted with a "racism that combined feelings of superiority and fear."

The immigration's impact was particularly acute in Arakan, one of less populated regions. In 1939, the British authorities, who were wary of the long term animosity between theRakhine Buddhists and the Rohingya Muslims, formed a special Investigation Commission led by James Ester and Tin Tut to study the issue of Muslim immigration into the Rakhine state. The commission recommended securing the border; however, with the onset of World War II, the British retreated from Arakan.

LAWYER JOKES........ FUNNY




1.

A physician, an engineer, and an attorney were discussing who among them belonged to the oldest of the three professions represented. The physician said, "Remember, on the sixth day God took a rib from Adam and fashioned Eve, making him the first surgeon. Therefore, medicine is the oldest profession."


The engineer replied, "But, before that, God created the heavens and earth from chaos and confusion, and thus he was the first engineer. Therefore, engineering is an older profession than medicine."


Then, the lawyer spoke up. "Yes," he said, "But who do you think created all of the chaos and confusion?"

2.

A lawyer's dog, running around town unleashed, heads for a butcher shop and steals a roast. The butcher goes to the lawyer's office and asks, "if a dog running unleashed steals a piece of meat from my store, do I have a right to demand payment for the meat from the dog's owner?" The lawyer answers, "Absolutely."


"Then you owe me $8.50. Your dog was loose and stole a roast from me today."


The lawyer, without a word, writes the butcher a check for $8.50. The butcher, having a feeling of satisfaction, leaves.


Three days later, the butcher finds a bill from the lawyer: $100 due for a consultation.

3.

A young lawyer, starting up his private practice, was very anxious to impress potential clients. When he saw the first visitor to his office come through the door, he immediately picked up his phone and spoke into it," I'm sorry, but my caseload is so tremendous that I'm not going to be able to look into your problem for at least a month. I'll have to get back to you then." He then turned to the man who had just walked in, and said, "Now, what can I do for you?" 

"Nothing," replied the man. "I'm here to hook up your phone." 

4.

An independent woman started her own business. She was shrewd and diligent, so business kept coming in. Pretty soon she realized she needed an in-house counsel, and so she began interviewing young lawyers.


"As I'm sure you can understand," she started off with one of the first applicants, "in a business like this, our personal integrity must be beyond question." She leaned forward. "Mr. Peterson, are you an 'honest' lawyer?"


"Honest?" replied the job prospect. "Let me tell you something about honest. Why, I'm so honest that my dad lent me fifteen thousand dollars for my education and I paid back every penny the minute I tried my very first case."


"Impressive. And what sort of case was that?"


He squirmed in his seat and admitted, "My dad sued me for the money."

5.

One day in Contract Law class, Professor Jepson asked one of his better students, "Now if you were to give someone an orange, how would you go about it?" 

The student replied, "Here's an orange." 

The professor was livid. "No! No! Think like a lawyer!" The student then recited, "Okay, I'd tell him, 'I hereby give and convey to you all and singular, my estate and interests, rights, claim, title, calim and advantages of and in, said orange, together with all its rind, juice, pulp, and seeds, and all rights and advantages with full power to bite, cut, freeze and otherwise eat, the same, or give the same away with and without the pulp, juice, rind and seeds, anything herein before or hereinafter or in any deed, or deeds, instruments of whatever nature or kind whatsoever to the contrary in anywise notwithstanding..."
