...The structure of the earth The earth has three major parts-the land part or lithosphere, the water part or hydrosphere and the air part or atmostpere. The lithosphere is the surface on which you live . It is also the earth solid sphere consisting mainly of massive rocks. The massive rocks form large land masses called continent and small island groups . Different land form such as mountains,hills,valleys,plateaus and plains make up the lithosphere. The hydrosphere include all water forms such as oceans,seas,rivers,lakes,and groundwater found beneath the earth. Geologists or scientists who specialize on the history and composition of earth study carefully these two major parts of the earth. They study the different layers of the earth and what each layer is made of. You see only the surface of the earth – the oceans, seas, rivers, rocks, and soil. They cover the earth just like the thick peeling of the pomelo or orange fruit. When you cut open the pomelo, you see layers of pulp inside it. If the earth were cut open, you will see that it is made of three layers. They are the crust, matle and the core. The topmost layer of the earth is the crust which is made of solid rock. It is thicker under the continents; approximately between 11 to 35 kilometres. But under the oceans, it can be 5 to 12 kilometres thick only. At the lower boundary...

...Theory : The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. The 4017 is an integrated circuit which has been designed to count pulses. It has 16 pins and looks like any other 16 pin integrated circuit. They can be used in timing circuits and are often used to switch on and off LEDs or motors or other circuits. They are versatile and relatively simple to put together. Counters such as the 4017B are cheap and yet surprisingly useful. The 4017 is most useful when combined with a timer such as a 555 based circuit. The pulse from the 555 timer can be used to activate the 4017B circuit. A 555 a stable circuit is used to pulse the 4017B at regular intervals. The pulse from the 555 IC is generated from pin 3. In the circuit seen below, pin 3 of the 555 IC feeds into pin 14 of the 4017B (called ‘clock in’). When this occurs pin ‘A’ of the 4017B emits current, lighting its LED. The next pulse from the 555 IC results in pin ‘B’ of the 4018B IC emitting current and lighting its LED. Description of Design: In our project we aimed to display a simple design to clear the Idea of our circuit . We made a white and rectangular shape box, and put the LEDs with the push and switch at its flat. That will make it easy to turn On and off without seeing the...

...How IC 555 timer works? Fundamentals of IC 555 timer & its basic applications VSagar • December 16, 2011 This article was first written on 16 Dec. 2011 and now it is rewritten in simple language with more practical approach, due to huge demand from visitors. Pin-wise functioning of IC555 timer Pin-1, GROUND: It is the GROUND PIN of the IC. The negative terminal of DC power supply or battery is connected to this pin. Here note that IC555 works always on single rail power supply and NEVER on dual power supply, unlike operational amplifiers. Also note that this pin should be connected directly to ground and NOT through any resistor or capacitor. If done so, the IC will not function properly and may heat up and get damaged. This happens because all the semiconductor blocks inside the IC will be raised by certain amount of stray voltage and will damage the IC. Refer the block diagram of the IC for more details. For more details read elaborate collection of FAQ on this IC. Pin-2, TRIGGER It is known as TRIGGER PIN. As the name suggests in triggers i.e. starts the timing cycle of the IC. It is connected to the inverting input terminal of trigger comparator inside the IC. As this pin is connected to inverting input terminal, it accepts negative voltage pulse to trigger the timing cycle. So it triggers when the voltage at this pin LESS THAN 1/3 of the supply voltage (Vcc). In number of applications, the IC must be triggered by a pulse. The amplitude and minimum pulse width...

...Teaching Critical Thinking with Electronic Discussion Steven A. Greenlaw and Stephen B. DeLoach Abstract: One of the products of a liberal undergraduate education is the ability to think critically. In practice, critical thinking is a skill that economics students are supposed to master as they complete their studies. However, exactly what critical thinking means is generally not well defined. Building on the literature on critical thinking, the authors examine how electronic discussion can be used effectively to teach this skill. Because of the multiplicity of views expressed, the asynchronous nature of the technology, and the inherent positive spillovers that are created, electronic discussion appears to provide a natural framework for teaching critical thinking. Key words: class discussion, critical thinking, distance learning, electronic discussion JEL code; A2 One of the products of a liberal undergraduate education is the ability to think critically. This should be particularly true for economics students who. after all, are ostensibly taught the discipline's version of critical thinking—the economic way of thinking. It is ironic then, that relatively little has been published on effective strategies for teaching critical thinking in economics.' This is not an original criticism. In his seminal article on research in pedagogy, Fels (1969) identified critical thinking as an area ripe for teaching and exploration by economists, Fels's critique, "rarely is a concerted effort...

...CONTE N T S CHAI R M A N ’ S LETTE R DEAR SH AREH OL DERS FY2012 has been a good year for your Company. The key financial results were: ¥ Consolidated revenues increased by 30% to Rs. 96.7 billion in FY2012. ¥ Earnings before interest, taxes, depreciation and amortization (EBITDA)1 rose by 55% to Rs. 25.4 billion. ¥ Profit after Tax (PAT)2 grew by 45% to Rs. 15.3 billion. ¥ Diluted Earnings per Share (EPS) increased from Rs. 64.9 in FY2011 to Rs. 83.8 in FY2012. I am particularly delighted by four developments. First, your Company succeeded in yet another blockbuster generic launch in the USA under 180days marketing exclusivity. Dr. Reddy’s launched olanzapine 20 mg tablets, the generic version of the brand Zyprexa®. Olanzapine is used to treat schizophrenia and bipolar disorder. This product has added around USD 100 million to your Company’s revenues for FY2012. Second, the biosimilars business continues along its impressive growth path. In my letter to you last year, I had discussed the critical importance of developing biosimilars in the years to come. I am happy to note that your Company’s global biosimilars business grew by 45% over last year and recorded sales of USD 26 million. Today, the biosimilars portfolio of Dr. Reddy’s constitutes (i) filgrastim, (ii) peg-filgrastim, (iii) rituximab and (iv) darbepoetin alfa, which have commercial presence in 13 countries among emerging markets. These are helping to treat patients suffering from cancer — and at prices that...

...22000 ESSENTIAL WORDS FOR IELTS AND TOEFL Cũng có 1 chút kinh nghiệm về kỳ thi IELTS, nên hôm nay chia sẻ cùng mọi người. Muốn đạt điểm cao ở kỳ thi IELTS, có 1 điểm rất quan trọng mà Bear nghĩ ai cũng biết: LUYỆN TẬP THƯỜNG XUYÊN. Tuy nhiên, cũng có 1 điểm cực kỳ quan trọng mà đa số thường không chú trọng lắm. Đó là phần từ vựng dạng ACADEMIC (học thuật). Nên để đạt điểm cao trong kỳ thi IELTS, ôn luyện từ trong quyển 22.000 từ THI TOEFL/IELTS của Harold Levine là cực kỳ cần thiết. Mỗi ngày chỉ cần học 3 từ, thì lượng từ vựng của bạn sẽ tăng đáng kể. Số từ vựng này giúp bạn trong cả 4 phần thi LISTENING / SPEAKING / READING / WRITING. Ví dụ: Nếu bạn dùng từ: SIMULTANEOUSLY thay cho từ AT THE SAME TIME, hay PORTABLE thay cho từ EASY TO CARRY hay MITIGATE thay cho từ LESSEN … trong phần WRITING và SPEAKING thì điểm của bạn sẽ cao chót vót không ngờ luôn đấy. Chưa kể, nhất là trong phần READING, những từ trong quyển sách này xuất hiện nhiều lắm, và cả LISTENING nữa chứ. Sự lợi hại của quyển sách này, chắc chắn chỉ khi nào học rồi, bạn mới thấy rõ. Quyển này (nhà xuất bản TPHCM) đã hết bán rồi. Nên nếu bạn nào cần phôtô thì liên lạc Uyên Uyên: UyenUyen@englishtime.us Tuy nhiên mỗi tuần Bear vẫn sẽ post lên đây 20 từ trong quyển sách đó, để nếu bạn nào ở xa, vẫn có thể học được. Đương nhiên mỗi người có 1 cách học riêng và trí nhớ khác nhau. Có người nhìn qua là nhớ liền, có người nhìn hoài vẫn không nhớ, nên Bear suggest...
