QUES: Prompted by legislation in various countries mandating increased bulb efficiency, new "hybrid" incandescent bulbs have been introduced by Philips. The "Halogena Energy Saver" incandescents can produce about 23 lm/W; about 30 percent more efficient than traditional incandescents, by using a reflective capsule to reflect formerly wasted infrared radiation back to the filament from which it can be re-emitted as visible light. This concept was pioneered by Duro-Test in 1980 with a commercial product that produced 29.8 lm/W. More advanced reflectors based on interference filters or photonic crystals can theoretically result in higher efficiency, up to a limit of about 270 lm/W (40% of the maximum efficacy possible). Laboratory proof-of-concept experiments have produced as much as 45 lm/W, approaching the efficacy of compact fluorescent bulbs.
Which company introduced hybrid incandescent bulbs?

ANS: Philips

QUES: During a deposition filed for the 1887 trial, Italian inventor Antonio Meucci also claimed to have created the first working model of a telephone in Italy in 1834. In 1886, in the first of three cases in which he was involved, Meucci took the stand as a witness in the hopes of establishing his invention's priority. Meucci's evidence in this case was disputed due to a lack of material evidence for his inventions as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901. Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. However, due to the efforts of Congressman Vito Fossella, the U.S. House of Representatives on June 11, 2002 stated that Meucci's "work in the invention of the telephone should be acknowledged", even though this did not put an end to a still contentious issue.[N 17] Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions.[N 18]
How many court trials did Meucci participate in?

ANS: 3

QUES: After fourteen consecutive years of economic growth, Greece went into recession in 2008. By the end of 2009, the Greek economy faced the highest budget deficit and government debt-to-GDP ratios in the EU. After several upward revisions, the 2009 budget deficit is now estimated at 15.7% of GDP. This, combined with rapidly rising debt levels (127.9% of GDP in 2009) led to a precipitous increase in borrowing costs, effectively shutting Greece out of the global financial markets and resulting in a severe economic crisis.
What did the Greek economy have the highest of at the end of 2009?

ANS: budget deficit

QUES: Shias believe that Imamah is of the Principles of Faith (Usul al-Din).As the verse 4:165 of quran expresses the necessity to the appointment of the prophets; so after the demise of the prophet who will play the role of the prophet; till the people have not any plea against Allah.So the same logic that necessitated the assignment of prophets also is applied for Imamah.That is Allah Must assign someone similar to prophet in his attributes and Ismah as his successor to guide the people without any deviation in religion. They refer to the verse (...This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion...) 5:3 of Quran which was revealed to the prophet when he appointed Ali as his successor at the day of Ghadir Khumm.
Who must assign a successor after the demise of a prophet?

ANS:
Allah
