How many tetrahedral and octahedral voids are present in HCP lattice?
First note that there is no HCP lattice, only HCP crystal structure which is built by adding two atom motif to a simple hexagonal lattice. Even with this correction the question as asked is not clear. It can be made precise by either askingHow many tetrahedral and octahedral voids per atom are there in an HCP crystal? oathHow many tetrahedral and octahedral voids per unit cell are there in an HCP crystal structure.The answer to the first question is that the number of tetrahedral voids per atom is two and the number of octahedral voids per atom is one. These are the same as those for Cubic Close-Packed (CCP) structure.To answer the 2nd question we should note that the primitive unit cell of the HCP structure contains two atoms. Thus the previous answers per atom have to be multiplied by 2 to get answers per unit cell. So there are 4 tetrahedral voids and two octahedral voids per primitive unit cell of the HCP structure.
What is the one thing which you think should be present at LNMIIT?
Guys I passed out in 2011. My answer is more from that era than the present one. I felt that these were needed even back then..Some kind of fee control mechanism. An attitude for sports (atleast a far better one than when we left! Need to attend more sports fests in various colleges!)An attitude for academics, especially coding/programming. A Book Reading club that would eventually be as huge and awesome as the LNMIIT Quiz Club.Six-monthly review of every student - his academic performance, his extra-curricular achievements - with somebody like APS sir. Sex-ed classes. Coz porn..is entertainment, not education! A swimming pool (co-ed wala ;))As others have already pointed out, a visionary leader is necessary to bring about these changes. A radical change is necessary, rather than incremental steps to just improve placements.
Is BCCI a part of the State under article 12 of the Indian Constitution?
No it is Not..BCCI is an autonomous Private organisation registered under Tamilnadu register of society Act 1975.Article 12 of the Indian Constitution states that “In this part, unless the context otherwise requires, “the State” includes the Government and Parliament of India and the Government and the Legislature of each of the States and all local or other authorities within the territory of India or under the control of the Government of India”In Zee Telefilms Ltd and Anr vs. Union of India and Ors case in 2005 Apex Court elaborately discussed about the position of BCCI as an instrumentality of State under Article 12. Court squarely applied the test in Pradeep Kumar Biswas v. Indian Institute of Chemical Biology and held that since BCCI is not financially, functionally and administratively controlled by government cumulatively and so it cannot be held as a State and thus writ petition under Article 12 is not maintainable. Later in Muthiahs Case Supreme Court reaffirmed the decision in Zee Telefilms Case and it was held categorically that BCCI is a “private autonomous body and its actions have to be judged only like any other similar authority exercising public functions”. The Court also rejected the claim that every entity regulating the fundamental rights under Article 19 (1) (g) is a ‘State’ within the meaning of Article 12. It was held that the functions of the Board do not amount to public functions.Sources:Article 12: Meaning of “State”What Is The Business/Organizational Structure Of BCCI And Why Is It Registered In Tamil Nadu? - iPleadershttp://www.commonlii.org/in/jour...
What are the different opportunities if one completes the Delf-Dalf exam in French?
The DELF/DALF exam are a proof of your level in French. There are six degrees in total, for all six levels of the CEFR scale, namely A1, A2,B1, B2, C1, C2, ranging from the easiest to the most difficult.Professional opportunities can be any opportunity which a good level of French will provide you, depending on your career.DELF B1 is required to acquire the French nationality.Some French universities accept DELF B2 or DALF C1 as a proof of a sufficient level of French to study there (others require a different degree named TCF).Hope this helps,Angel, http://frenchlover.org
Do I have to write sat subject tests to go to UCLA to pursue computer science engineering?
Usually to get admission in any top tier university such as UCLA, you need to take the SAT and the SAT 2 Subject Tests.Now, UCLA doesn’t “require” SAT subject tests, they instead “strongly advise” you to, but in order have a higher chance at getting admitted than the thousands of others who apply, you pretty much need to.UCLA wants 2 SAT subject tests; 1 Math Level 2 and 1 of any science (Biology, Physics, Chemistry) if you are applying for an engineering/applied science, which you are.
What is the AP exam and what is its affect on my GPA or chance of acceptance in a good college if I'm an international student?
An AP exam is an achievement test in a particular subject. Scores range from 1 to 5 with 1 being the worst score and 5 being the best score. A good score indicates that you are able to do college level work in that subject. Sometimes, a college will award college credit for scores above a particular benchmark. (That depends on the college.)An AP exam score does not affect your GPA at all. A bad score would decrease your chance of admission (assuming you submitted it with your application, which I wouldn’t recommend.) A good score might enhance your chances, but it might not depending on whether or not the college is familiar with your high school. If you are coming from a high school the college has never heard of, a good AP exam score would validate the grade you received in the class.I don’t know your circumstances, but it is possible that you will not be able to take an AP exam as an international student. AP exams are administered by a participating high school. You must be able to get to a participating high school to take the exam, and they must agree to allow you to test with them. Registration is done through the school; you can find the instructions here: Registering for AP Exams.Note that you have missed the deadline to register for the 2017 exams. If you wish to take an AP exam in 2018, you would need to register sometime in February of that year.(answered March 3, 2017)
What number fits in the blank: 16, 06, 68, 88, __, 98?
Step 1: Invert the sequence upside down. you will find 19, 09, 98, 88 , _, 68Step 2: alternate the position of each digit in each number in the sequence. you will find 91, 90, 89, 88, _, 86. At this point it is clear that the missing number is 87. But to fit it with the original sequence go back undoing the steps.Step 3: Alternate the positions again. You will find 19, 09, 98, 88, 78, 68Step 4: Again invert the sequence upside down. you will find 16, 06, 68, 88, L8, 98.The closest possible digit I found similar to inverted 7 is L.
