The positron decay of ^15 O goes directly to the ground state of ^15 N; no excited states of ^15 N are populated and no gamma rays follow beta decay. Yet a source of ^15 O is found to emit gamma rays of about 0.5 MeV. Explain the origin of these rays. Solution gamma rays almost always accompanies other radioactive emmissions because it represents energy loss when the remaining nucleons reorganise into more stable arrangements. thus here in this problem the origin of gamma rays arise due to mass defect as per Einesteins theory of relativity..

The disease bullous pemphigoid results in the destruction of proteins within the basement membrane that hold the epidermis and dermis together. How would this likely affect the epidermis? Solution Bullous pemphigoid is an autoimmune disease. Due to the nature of the disease, the cohesion between the dermis and the epidermis is destroyed. The epidermis tends to separate from the dermis and in the intervening space, body fluids fill up, giving the appearance of lesions. The colour and size of the lesions vary. In some patients they may cover large parts of the anatomy. The lesions when disturbed burst, spilling their contents. This may further lead to secondary infections and provide a pathway for pathogens to enter the body..

QUESTION 8 1.00000 P Financial intermediaries are different from investment banking houses in that financial intermediaries issue their securities to obtain funds from savers and then use the fund to purchase other business\'s securities, while investment banking houses do not issue their securities. Instead, savers\' money merely passes through investment banking houses. e True False Solution Answer: This statement is false. Financial Intermediaries- These are the financial institutions that work as mediator between two parties, they include commercial banks, investment bank, mutual funds, NBFCs, pension fund etc. These intermediaries channel funds from those who have it in excess to those who need funds. Investment banking- It is special branch of banking that provides many services like underwriting, broking, portfolio management, M&A, restructuring, consultancy etc. These help the new firms to raise capital from the market and go public by issuing shares to the general public..

Post your response to the following focus questions: Describe a sole proprietorship and discuss its advantages and disadvantages. Describe a partnership and discuss its advantages and disadvantages. Describe a corporation and discuss its advantages and disadvantages. Describe an S corporation and discuss its advantages and disadvantages. Solution Broadly speaking for conducting any type of Business activity we require to have a Business entity. If the Business entity is owned and operated and managed by a single paerson then such Business entity is called a sole Proprietorship. It is most simple and subjected to least terms & conditions governing the business activities. The main disadvantages includes personal liability of the owner/ propreitor, which is unlimited. A single person being at the helm of affairs poses limitations on the development and growth of the business. Propreitorship has its death with the death of the owner. A Partnership as the word suggest is that form of Business entity which is owned by two or more persons and formed under an agreement signed by all owners for some common purpose/ goal and or objectives. A partnership firm is more complicated than the sole propreitorships, two or more persons as owners may give advatages of sharing resources, knowledge, skills which are essential for setting up of businesses of sizes unmanageable by a single person. Pooling diversity of partners helps in the development and growth of the Business entity. Like sole propreitorship, the partners under partnerships may be subjected to unlimited liabilities under or arising out of the business activities of the Partnership firm. There are additional set of rules & regulations under the law of the land governing the partnership firms. The third and the most prefered form of business entity is an incorporated firm called corporation and or company. A corporation/ company is different from its owners. This form of business entity draws difference between the owner and management of the business entity. Unlike the earlier set ups of Sole Propreitor and Partnership, the business activies are conducted neither by sole owner nor by partners but managers who are considered to be having different identity than the business entity which is also considered as a legal person. A corporation can be sued and it can also sue others in the court of law.A corporation comes into existence with its incorporation documents such as Memorandum of Understanding, Articles of Associations, Delegation of Powers etc. These documents required for giving birth to the corporation varies from state to state, nation to nation, lews of the land under whose jurisdiction it falls. The main advantage of a corporation is to give limited liability to its owners who are called share holders and its business activities are conducted by the professionals having required qualifications and skills. Just like its birth, its death is not related to that of its share holders (owners).

Linear Algebra Hello. I need help with my practice final. I am not trying to copy. I want to see If I am doing it right So please help. Thank you very much! Here\'s the problem Let V and W be (finite-dimensional) vector spaces. In fact, unless otherwise stated in one of the problems or definitions below you may assume that dim V n and dimW m. Also, unless otherwise stated, let T V W be a linear transformation. Definitions and Basic Results 1. The kernel of T, written ker T, is the set of vectors UE v such that T(i) 30w. 2. The range of T, written range T is the set of vectors i e W such that T(i) if for some i E V. 3. T is injective means that whenever i E V then T(ii) T(i2) if and only if ii J v2 4. T is surjective means range T W 5. T is bijective if and only if it is both injective and surjective. 6. T is called a linear operator if V W 7. Let T be a linear operator in V and let u be subspace of V. u is said to be invariant under T if T(ii) Eu for every i Eu 8. Let u and u be aces of V (a) The sum of these subspaces, written uitu2, is the set of vectors i EV that can be written as a sum of vectors ii ii2 where ii E uh and ii2 Eu2. (b) V is said to be a direct sum of u and up, written V Juh Du2, if and only if for every if E V there exists a unique pair of vectors iii E ui and ii2 Eur such that if ii ii2. Examples R2 z-axis) (y-axis). Ra (ary-plane) axis A) span span Fact V u if and only if v un +uo and un nu Solution if T is injective then there should be a map of v in w for every v belonging to V and w belonging to W. Consider the basis of W as all elements are maped then the dim of W should be at least equal to the dimension of V as linear transformation map each basis element of V to some basis element in W If T is surjective then same argument above applies to just opposite because now mapping covers all the elements of W. if T is bijective then it is both injective and surjective .So now only equality can hold hence dim(V) = dim(W).

Many nations, including the US, already maintain a national DNA database of samples collected during criminal investigations, but there are often questions of whether such databases should be expanded to include more individuals, or whether their use is ethical at all. What arguments can you make for and against \"banking\" DNA profiles (i.e. \"genetic fingerprints\" based on STRs, not necessarily full genome sequences) in a database? Do you believe such databases are ethical or an invasion of privacy? Should it be mandatory for some or all individuals? What restrictions would you place on it? Solution ARGUMENTS FOR: A DNA database covering the entire populace and each guest to the UK, as upheld by Lord Justice Sedley, would spare huge measures of police time and help clear up violations quicker. The individuals who do nothing incorrectly have nothing to fear and ought to be consoled. The present framework - the DNA of each one of those captured for recordable offenses, liable or not, is held - is specific and wasteful. Current practice is uncalled for: ethnic minorities and youngsters are over-spoken to, making hatred and hostile to police feeling. Two-in-five dark men have their DNA on record, as against less than one-in-ten whites. The world has changed: universal versatility implies that potential fear based oppressors can travel every which way, frequently on false papers. ARUGMENTS AGAINST: It would be a definitive stride making progress toward a \'The government\' state: Britain would turn into \'a country of suspects. Whatever the utility of DNA tests, there is something inalienably exasperating about entering each infant on a database during childbirth. A national DNA bank would be enormously costly and bureaucratic. It is harming to the picture of the UK - \'Welcome to Britain: now give a mouth swab\'. DNA data could be mishandled by degenerate police and others wrongfully passing data to unapproved individuals. PRIVACY ISSUE: Individual data is now held by gatherings in the private division, if individuals can believe the private part then they ought to have the capacity to confide in the Government. In 2010, the UK Government promised to roll out improvements to the period of time DNA tests are kept in the UK National DNA Database. These were incorporated into the 2012 Protection of Freedoms Act. These progressions guarantee that the DNA (and fingerprints) of people captured yet not indicted an offense is held for a most extreme of 5 years. The DNA Identification Act of 1994 unequivocally permits database records to be made accessible for innovative work the length of all actually identifiable data is expelled. It need not be mandatory for all the individuals but as a matter of national security it should be taken into consideration.Some restrictions like the privacy issue and the information of that should not be accessed to everyone instead the government should be in a position to give the required information neccesary and sho.

How are nuclear pores and porins in the membrane different? Solution Nuclear pores: are large protein complexes that cross the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus. There are about an average of 2000 nuclear pore complexes (NPCs), in the nuclear envelope of a vertebrate cell, but it varies depending on cell type and the stage in the life cycle.[1] The proteins that make up the nuclear pore complex are known as nucleoporins. About half of the nucleoporins typically contain solenoid protein domains—either an alpha solenoid or a beta-propeller fold, or in some cases both as separate structural domains. Each NPC contains at least 456 individual protein molecules and is composed of 30 distinct proteins (nucleoporins). NuclearPorins:nucleoporins are a family of proteins which are the constituent building blocks of the nuclear pore complex (NPC).[1] The nuclear pore complex is a massive structure that extends across the nuclear envelope, forming a gateway that regulates the flow of macromolecules between the cell nucleus and the cytoplasm. Nuclear pores in turn allow the transport of water-soluble molecules across the nuclear envelope. Nucleoporins, a family of around 30 proteins, are the main components of the nuclear pore complex in eukaryotic cells. Nucleoporin 62 is the most abundant member of this family.[2] Nucleoporins are able to transport molecules across the nuclear envelope at a very high rate. A single NPC is able to transport 60,000 protein molecules across the nuclear envelope every minute..

How many allotropic forms does uranium have? Discuss the effect of allotropic transformation on the properties of uranium. Solution Metallurgically, uranium metal may exist in three allotropic forms: orthorhombic(alpha), tetragonal (beta), or body-centered cubic (gamma), and may be alloyed with other metals to alter its structural and physical properties to suit the application. Uranium undergoes allotropic transformations around 665 and 770°C.When room temperature alpha uranium is heated melted it undergoes three distinct transformations, but the transformations which occur while cooling are important.when the liquid metal solidifies.Slow cooling results in soft metal, while rapid cooling inreases its hardness. At room temperature uranium exists in alpha phase which is semi plastic and corrosive. When heated to beta phase it becomes brittle and hard. The gamma phase is most suited for working as it can be forged, drawn and extruded..

Explain homologous recombination between human X and Y chromosomes. Solution X and Y chromosomes homology: The X chromosome is a large sub metacentric chromosome, which contains many genes on it. Among these genes most are unrelated to sex. The Y chromosome is a small acrocentric chromosome. In this chromosome 83 active genes are present, in which most are related to sex determination and spermatogenesis. The gene of Y chromosome is a pseudogene. It clearly explains the common evolutionary origin. Homologous recombination between human x and y chromosomes: In human X and Y chromosomes several homological sequences of regions are identified. Generally the chromosomes X and Y are paired during in meiosis and undergo crossing over. these regions are called pseudoautosomal regions., PAR1 and PAR2. PAR1 crossover is very important in male meiosis. in this chromosomes proper segregation was occur. where they exchange only DNA within the pseudoautosomal region at the distal short arms of both chromosomes. However, it has been suggested that aberrant recombination involving other segments of high homology could be responsible for the production of X/Y translocations..

By looking at the skeleton of a python, a boa contricor and a legless amphbian, can you find evidence that would lead you to think the ancestor of those organisms had four legs? What is this evidence? Solution Fossil evidence suggests that snakes such as pythons and boa constrictors, might have evolved from burrowing lizards. Hunting in tiny burrows and tunnels favored these streamlined animals, with narrow pelvic bones and smaller legs. Eventually, legs became hindrance more than an advantage. There is dispute in the scientific community about whether snakes evolved from terrestrial lizards or marine reptiles, but the evidence clearly indicates that proto-snakes had legs..

File PrintCoded.java (shown above) contains an incomplete program. The goal of the program is to take as input strings from the user, and then print out coded (encrypted) versions of those strings, by replacing each letter with another letter. Complete that program, by defining a printCoded function, that satisfies the following specs: Function printCoded takes three arguments, called word, sources, targets. They are all strings. Function printCoded processes the letters of word one by one, in the order in which they appear in word. For every such letter X, the function processes X as follows: If X is equal to the character at position P of sources, then the function prints the character at position P of targets. Otherwise, the function prints X. Note that arguments sources and targets are hardcoded in the main function, the user cannot change those values. The user can only specify the value of word. IMPORTANT: you are NOT allowed to modify in any way the main function. This is an example run of the complete program: Solution PrintCoded.java import java.util.Scanner; public class PrintCoded { public static void main(String[] args) { Scanner in = new Scanner(System.in); String sources = \"abcdefghijklmnopqrstuvwxyz\"; String targets = \"bcdefghijklmnopqrstuvwxyza\"; while (true) { System.out.printf(\"Enter some word, or q to quit: \"); String word = in.next(); if (word.equals(\"q\")) { System.out.printf(\"Exiting...\ \"); System.exit(0); } printCoded(word, sources, targets); System.out.printf(\"\ \ \"); } } public static void printCoded(String word, String sources, String targets){ for(int i=0; i.
