The von Neumann architecture describes a general framework, or structure, that a computer\'s hardware,programming, and data should follow. It is an abstract model for computer architecture: it assumes that execution work by decoding an instruction then getting the operands and computing the result then also writing the result back to memory and finally it will repeat these thinsg again and again. So he has given a very simple structure without the actual implementations. So the whole computer is to two be divided in main 4 parts which actually are the 4 funtions that a computer will do i.e. it will have to take input so input devices, then it will do some processing hence the CPU then this result might be stored in Memory or given as output to Output devices. So by this architeture anyone can understand basic computer.

The oxide is ionic if there is charge transfer from one atom to another, i.e. when the electronegativity difference is large between O and the other element. This is the case for metals like Mg and Li. The oxide is molecular if the atoms share electrons equally, i.e. when the electronegativity difference is small between O and the other element. This is the case for the nonmetals like S, P, N and Xe.

The answer is: b) water decomposes first The standard oxidation potentials are: 2 F- => F2 + 2 e-, E(oxidation) = -2.87 V 2 H2O => O2 + 4 H+ + 4 e-, E(oxidation) = -1.23 V Since H2O has a less negative oxidation potential, it is oxidized more easily than F-. Thus when a solution of F- ions in H2O is electrolyzed, the H2O will decompose first into O2 and H+, while the F- ions remain unreacted.

Ques-1: How does silica get into the macrophages? what type of coat do you expect on the vesicles? Answer: Silicosis: Alveolar macrophages have associated with presence of \"surface scavanger receptors-A\" to recognize silica particle and these particles are going to form \"a non-opsonized coat\" on the surface of macrophages and FCR- mediated uptake. This coat formation is completely depends on “the negatively changed ligands of silica particles” & it is carried into the cell via activation of Rac and RhoA GTPases & IP3. This non-opsonized silica uptake into the cell is going to trigger phagosome formation by the lysosomal vesicles to mediate denaturation but failure of cell to denaturate it finally result in lysis of phagolysosomal membranes to leak the internal contents into the cytosplasm Ques-2: The silica particles inside the lysosome to from a endolysosome-to-phagosome fusion finally trigger leakage of internal contents into the cytoplasm of macrophages in alveoli of lung. These events are followed by activation of mitochondria hyperpolarization signaling pathway finally result in \"generation of caspase-9 and -3\" as a result apoptosis or cell death even the patient is not working in the coal mine Solution Ques-1: How does silica get into the macrophages? what type of coat do you expect on the vesicles?

Scenario 1 : 1) Dec 31st Profit & loss Appropriation/ reserves Account Dr $1 / share To Proposed Dividend $ 1/ share 2) 20th Jan Proposed dividend Account Dr $ 1/ share To Bank $ 1/ share Scenario 2: 1) Dec 31st Profit & loss Appropriation/ reserves Account Dr $5 / share To Proposed Dividend $ 5/ share 2) 20th Jan Proposed dividend Account Dr $ 5/ share To Bank $ 5/ share Notes: Dividend is the source of income of shareholders when they invest money in shares for gaining the dividend. On the other hand, when company declares the dividend for shareholder, it will be the deduction of its net profit. For transferring dividend out of net profit, we make the profit and loss appropriation account. Following are the journal entries of dividends 1. When dividend is proposed by company out of net profit. Profit and Loss Appropriation Account Debit Proposed Dividend Account Credit 2. When Proposed dividend is paid by Company Proposed Dividend Account Debit Bank Account Credit 3. When Dividend is Declared Out of Retained Earning Retained Earning Account Debit Dividend Account Credit 4. When Such Dividend is Paid Dividend Account Debit Bank Account Credit Examples : Let’s assume that the Reliance Corporation, on Dec. 20, 2011, declared a cash dividend of Rs. 2 per share on 4,00,000 shares payable April 1, 2012, to all stockholders of record March 15. The following journal entries are required: 1. Date of declaration, Dec. 20, 2011 Retained Earning Account Debit 8,00,000 Dividend Payable Account Credit 8,00,000 2. When dividend is paid on Date of payment, April 1, 2012 Dividend Payable Account Debit 8,00,000 Bank Account Credit 8,00,0000 Important : Sometime company may not have sufficient cash, at that time, company may give his fully paid up new equity shares or other investments. So, we will not credit the bank account but we will credit the equity share capital or investment. Solution Scenario 1 : 1) Dec 31st Profit & loss Appropriation/ reserves Account Dr $1 / share To Proposed Dividend $ 1/ share 2) 20th Jan Proposed dividend Account Dr $ 1/ share To Bank $ 1/ share Scenario 2: 1) Dec 31st Profit & loss Appropriation/ reserves Account Dr $5 / share To Proposed Dividend $ 5/ share 2) 20th Jan Proposed dividend Account Dr $ 5/ share To Bank $ 5/ share Notes: Dividend is the source of income of shareholders when they invest money in shares for gaining the dividend.

Presence of her parents and siblings made her choose a profession which she would not have in general against her inherent personality. This suggests that there was a sort of confusion in her mind regarding her decision and she might have passed through stage of identity crisis/moratorium in search for her own identity. Althoug influenced, she found her own one and practised it thenafter.

From the graph provided, it can be observed Serine is present in highest number of proteins before the labile Asn. Threonine is the second most numorously occuring amino acid. Serine and Threonine are polar uncharged amino acids which are occuring before Asn. Also, Lysine (polar, positively charged amino acid) is present in almost equal number of casese as Threonine. In some cases, Leucine and Valine are occuring (both are non-polar). As far as the amino acid occuring after the labile Asn is concerned, in maximum cases Glycine (non-polar amino acid) is there. Serine and Threonine rank second and third based on the number of proteins in which they are present after the labile Asn.
