‰M‰Mwm Cixþvi Cék² I Dîi
gBs‡iwRƒj eBGqi 1g cÎ AwZwiÚ Ask 275 ‰m‰mwm cixÞvi cÉk² I Dîi 1. Dhaka Board-2015 English (Compulsory) 1st Paper Read the passage. Then answer the questions below. The National Memorial at Savar is a symbol of the nation's respect for the martyrs of the War of Liberation. It is built with concrete, but made of blood. It stands 150 feet tall, but every martyr it stands for stands so much taller. It is an achievement the dimension of which can be measured, but it stands for an achievement, which is immeasurable. It stands upright for the millions of martyrs who laid down their lives so that we may stand upright, in honour and dignity, amongst the nations of the world. Most prominently visible is the 150 feet tower that stands on a base measuring 130 feet wide. There are actually a series of 7 towers that rise by stages to a height of 150 feet. The foundation was laid on the first anniversary of the Victory Day. There is actually a plan to build a huge complex in several phases. The entire complex will cover an area of 126 acres. The plan of this complex includes a mosque, a library and a museum. The relics of the Liberation War will be kept in the museum. They will ever remind our countrymen and all who would come to visit museum of the valiant struggle and supreme sacrifices of a freedom loving people. Here also will be a clear warning to all oppressors that the weapons of freedom need not be very big, and that oppression will always be defeated. -

Physics 1928 OWEN WILLANS RICHARDSON
Physics 1928 OWEN WILLANS RICHARDSON <<for his work on the thermionic phenomenon and especially-for the discovery of the law named after him>> Physics 1928 Presentation Speech by Professor C. W. Oseen, Chairman of the Nobel Committee for Physics of the Royal Swedish Academy of Sciences Your Majesty, Your Royal Highnesses, Ladies and Gentlemen. Among the great problems that scientists conducting research in electro- technique are today trying to solve, is that of enabling two men to converse in whatever part of the world each may be. In 1928 things had reached the stage when we could begin to establish telephonic communication between Sweden and North America. On that occasion there was a telephone line of more than 22,000 kilometres in length between Stockholm and New York. From Stockholm, speech was transmitted via Berlin to England by means of a cable and overhead lines; from England by means of wireless to New York; then, via a cable and lines by land, over to Los Angeles and back to New York, and from there by means of a new line to Chicago, returning finally to New York. In spite of the great distance, the words could be heard distinctly and this is explained by the fact that there were no fewer than 166 amplifiers along the line. The principle of construction of an amplifier is very simple. A glowing filament sends out a stream of electrons. When the speech waves reach the amplifier, they oscillate in tune with the sound waves but are weakened. The speech waves are now made to put the stream of electrons in the same state of oscillation as they have themselves. -
Chapter 6 the Aftermath of the Cambridge-Vienna Controversy: Radioactivity and Politics in Vienna in the 1930S
Trafficking Materials and Maria Rentetzi Gendered Experimental Practices Chapter 6 The Aftermath of the Cambridge-Vienna Controversy: Radioactivity and Politics in Vienna in the 1930s Consequences of the Cambridge-Vienna episode ranged from the entrance of other 1 research centers into the field as the study of the atomic nucleus became a promising area of scientific investigation to the development of new experimental methods. As Jeff Hughes describes, three key groups turned to the study of atomic nucleus. Gerhard Hoffman and his student Heinz Pose studied artificial disintegration at the Physics Institute of the University of Halle using a polonium source sent by Meyer.1 In Paris, Maurice de Broglie turned his well-equipped laboratory for x-ray research into a center for radioactivity studies and Madame Curie started to accumulate polonium for research on artificial disintegration. The need to replace the scintillation counters with a more reliable technique also 2 led to the extensive use of the cloud chamber in Cambridge.2 Simultaneously, the development of electric counting methods for measuring alpha particles in Rutherford's laboratory secured quantitative investigations and prompted Stetter and Schmidt from the Vienna Institute to focus on the valve amplifier technique.3 Essential for the work in both the Cambridge and the Vienna laboratories was the use of polonium as a strong source of alpha particles for those methods as an alternative to the scintillation technique. Besides serving as a place for scientific production, the laboratory was definitely 3 also a space for work where tasks were labeled as skilled and unskilled and positions were divided to those paid monthly and those supported by grant money or by research fellowships. -
A Laser (From the Acronym Light Amplification by Stimulated Emission of Radiation) Is an Optical Source That Emits Photons in a Coherent Beam
LASER A laser (from the acronym Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. The verb to lase means "to produce coherent light" or possibly "to cut or otherwise treat with coherent light", and is a back- formation of the term laser. Laser light is typically near-monochromatic, i.e. consisting of a single wavelength or color, and emitted in a narrow beam. This is in contrast to common light sources, such as the incandescent light bulb, which emit incoherent photons in almost all directions, usually over a wide spectrum of wavelengths. Laser action is explained by the theories of quantum mechanics and thermodynamics. Many materials have been found to have the required characteristics to form the laser gain medium needed to power a laser, and these have led to the invention of many types of lasers with different characteristics suitable for different applications. The laser was proposed as a variation of the maser principle in the late 1950's, and the first laser was demonstrated in 1960. Since that time, laser manufacturing has become a multi- billion dollar industry, and the laser has found applications in fields including science, industry, medicine, and consumer electronics.

Abstract. Soviet policy-makers, in order to aid and abet industrialisation, seem to have chosen science as an agent for development. Soviet science, mainly through the Academy of Sciences of the USSR, was driving the Soviet industrial development and a key element of the preparation of human capital through social programmes and politechnisation of the society. -

Appendices Due to Concerns Over the Quality of the Data Collected
APPENDIX A WSU 2014-19 STRATEGIC PLAN Appendix A: WSU Strategic Plan 2014-15 Strategic Plan 2014-2019 President Elson S. Floyd, Ph.D. Strategic Plan 2014-2019 Introduction The 2014-19 strategic plan builds on the previous five-year plan, recognizing the core values and broad mission of Washington State University. Goals and strategies were developed to achieve significant progress toward WSU’s aspiration of becoming one of the nation’s leading land-grant universities, preeminent in research and discovery, teaching, and engagement. The plan emphasizes the institution’s unique role as an accessible, approachable research institution that provides opportunities to an especially broad array of students while serving Washington state’s broad portfolio of social and economic needs. While providing exceptional leadership in traditional land-grant disciplines, Washington State University adds value as an integrative partner for problem solving due to its innovative focus on applications and its breadth of program excellence. The plan explicitly recognizes the dramatic changes in public funding that have occurred over the duration of the previous strategic plan, along with the need for greater institutional nimbleness, openness, and entrepreneurial activity that diversifies the University’s funding portfolio. In addition, the plan reaffirms WSU’s land-grant mission by focusing greater attention system-wide on increasing access to educational opportunity, responding to the needs of Washington state through research, instruction, and outreach, and contributing to economic development and public policy. While the new plan retains the four key themes of the previous plan, its two central foci include offering a truly transformative educational experience to undergraduate and graduate students and accelerating the development of a preeminent research portfolio.
