Assume you have decided to implement DFS so remote sites can access files and folders. What are the requirements for DFS? What are benefits of using DFS? What are the shortcomings and limitations? Please provide reference in APA format Solution There are many benefits: Unified namespace A DFS namespace links together shared folders on different servers to create a hierarchical structure that behaves like a single high-capacity hard disk. Users can navigate the logical namespace without having to know the physical server names or shared folders hosting the data. Location transparency DFS simplifies migrating data from one file server to another. Because users do not need to know the name of each physical server or shared folder that contains the data, you can physically move data to another server without having to reconfigure applications and shortcuts, and without having to re-educate users about where they can find their data. Storage scalability You can deploy additional or higher-performance file servers and present the storage on the new servers as new folders within an existing namespace. Namespace scalability Servers running Windows Server 2003, Enterprise Edition or Windows Server 2003, Datacenter Edition can host multiple domain-based DFS roots and stand-alone DFS roots. This feature improves the scalability of DFS, enabling you to build many large namespaces without having to add file servers to host the roots. Increased availability of file server data When multiple servers running Windows Server 2003 host a domain-based DFS root, clients are redirected to the next available root server if any of these servers fail, providing fault-tolerant data access. To ensure the availability of stand-alone DFS namespaces, you can create the root on a clustered file server. Alternate site selection based on cost By default, if a target in the same site as the users fails, or if no same-site target exists, DFS refers clients to a random target. If you configure the optional site costing feature, DFS can use the site information in Active Directory to locate an alternate target that has the lowest-cost network connection as defined by the administrator in the Active Directory Sites and Services snap-in. After site costing is enabled, clients can access data on DFS targets over the optimum network connection. Load sharing DFS provides a degree of load sharing by mapping a given logical name to shared folders on multiple file servers. For example, suppose that \\\\Company\\StockInfo is a heavily used shared folder. By using DFS, you can associate this location with multiple shared folders on different servers, even if the servers are located in different sites. Intelligent client caching When a user requests access to a target that is a part of a DFS namespace, a referral containing the target’s information is cached on the client. The next time the client requires access to that portion of the namespace, the client uses the cached referral instead.

A. What are two advantages that the use of green fluorescent protein (GFP) has over the use of fluorescent-labeled antibodies for studying the location and movement of a protein in cells? B. What is meant by empty magnification when taking images on a microscope? C. The lipid bilayers found in cells are fluid, yet asymmetrical in the composition of the monolayers. Is this a paradox? Explain your answer. D. Why do transmembrane domains of proteins typically fold into alpha helices or beta-barrels rather than exist as disordered chains? Solution A. The two advantages of GFPs over the use of fluorescent-labeled antibodies for studying the location and movement of a protein in cells are 1. They provide a means for identifying the genetically modified cells for physiological studies in unadultrarted living cells thus aviod artefacts arising due to permebilisation and cell fixation. 2. For the expression of other fluoroscent proteins a cofactor is required while GFPs exhibit intrinsic fluoroscence due to cyclisation of three amino acids Ser65-Tyr66-Gly67 and then undergo maturationm process. B. Empty magnification refers to the magnification of an image beyond its resolution power but without any improvement in the details of the image due to the limitations of the resolving power of the optical system..

A species has a diploid number of 2n. Meiosis I fails during spermatogenesis, the cytoplasm does not divide, and only one daughter cell is produced The resulting sperm fertilizes a normal ovum. What is the chromosomal complement of the 10pts embryo? Solution Answer : Meiosis 1 is a reductional division which results in two daughter cells with half the number of chromosomes. If the Meiosis 1 fails the resulting sperm is still a diploid, and when it fertilized the haploid ovum the embryo will carry 3 sets of chromosomes (polyploidy).Sperm contributes (XY) and ovum (X) resulting in polyploid. The chromosomal complement will be XXY.

A New Look at Bread and Roses In Bread and Roses, Bruce Watson argues that events of the Lawrence, Massachusetts, 1912 mill strike have long been \"relegated to history\'s ghettos\" (p. 3). Watson asserts that in the decades following the strike, fear of mill bosses prevented workers from revisiting the events of the winter of 1912. With the passing of time and the death of first-hand witnesses, the details faded. Watson seeks to rectify this and bring closer attention to the events in Lawrence. Even the name \"Bread and Roses,\" according to the author, is incorrectly identified as a slogan of this labor struggle (p. 3). Watson tells an engaging story of this strike that captured national attention from January to May 1912. The book moves from the beginning of the strike to its conclusion, concentrating on the actions and events of the laborers and their families, as well as the union leadership, specifically the International Workers of the World (IWW) and the American Federation of Labor. The author also includes examinations of mill owners, particularly William Wood of the American Woolen Company. Watson, however, is intent on unearthing the obscured details of the strike and union activity to provide the perspective of the workers and their families as they struggled to make a living. Bread and Roses is a history of working-class immigrants who came to Lawrence in hopes of obtaining a better life. Watson ties this experience into the larger concept of the American dream, as his subtitle suggests. The workers at the Lawrence mills struck because of a cut in pay. The Massachusetts legislature had mandated a reduction in work hours as of January 1, 1912. The mills, however, continued to pay the same hourly wage to their workers, resulting in a smaller pay envelope. The workers, while happy with the reduction in hours, desired the same weekly pay they received prior to the reduction. By 1912, most male textile workers did not make enough to support their families and required the labor of others within the family to make ends meet. This struggle to make a living and to support families in the United States is at the heart of Bread and Roses, and it informs each dramatic example provided by the author as he carries the reader from the combative beginning of the walkout through the desperately cold weeks as tension rose in Lawrence, and to the last negotiation that ended the strike five months later. As Watson moves through the major events of the strike, he dots his narrative with stories of individual workers and their families. One of the strengths of this work is the manner in which Watson presents the facts of the strike. After finding few memories within Lawrence among descendents of the strikers, the author strives to paint a sweeping picture of the conditions in Lawrence in the winter of 1912 as workers struck against the American Woolen Company. Drawing heavily from newspaper accounts of the strike and other secondary sources of the p.

A protein, called PHD (protein for retinoblastoma) a synthesized by a gene (Rb) on chromosome 13 in humans. When mutant or absent in the homozygous state in a retinal cell, there is a high likelihood of developing a cancerous condition of the eye called retinoblastoma. Nonmutant pRb binds with and temporarily inactivates E2F, a transcription factor that stimulates genes to produce proteins that initiate S phase of the mitotic cell cycle (thus, Rb is a negative regulator of cell division). When phosphorylated in response to a variety of normal stimuli, pRb normally releases E2F and cell division is stimulated. Thus, Rb is a tumor suppressor gene. (For a recent review, see H. Liu et al. (2004). \'Novel functions of the RB tumor suppressor.\" Current Opinions in Genetics and Development 14: 55-64. When retinoblastoma occurs in fannies, the disease tends to have an early onset and express bilaterally (both eyes). When sporadic (spontaneous, not inherited), it tends to show later onset and be unilateral (one eye only). Individuals who inherit a predisposition for the disease are Rb +/Rb- and may got retinoblastoma by having a mutation in the Rb+ allele Assume that two heterozygous parents have children. One would expect the Rb-/Rb- genotypic combination in a zygote (one-cell stage of an individual) to be characterized as: lethal (in viable or lasting a relatively short time) completely normal having a very low likelihood of developing retinoblastoma having unilateral retinoblastoma only Solution 3. Having a very low likelihood of developing retinoblastoma although, Rb-/Rb- is a normal genotype, but here while answering we would keep the possibility of somatic mutations alive. Children born with the normal gene can have some spontaneous mutations such that the function of Rb- with be mutated or lost resulting in loss of the function of the pRb protein resulting in uncontrolled cell growth..

What were the driving forces behind the creation of the FAA and ICAO? Solution FAA The Federal Aviation Administration is the aviation authority of the united states of america. It is responsible for setting up the federal aviation regulations (FAR), which are binding for all flight operations in the US. The FAA also provides air traffic control service at most control towers and all en-route air traffic control centers. FAA is the Federal Aviation Administration. As the Civil Aviation Authority of the USA, it is responsible for establishing aviation regulations in the US. These are known as FARs (Federal Aviation Regulations). In addition to its regulatory role, the FAA is also responsible for Airspace and Air Traffic Management, maintenance of Air Navigation Facilities infrastructure and has an active role in Research and Development of aviation related systems and technologies. ICAO - The International Civil Aviation Organization is was founded to set up international standards in aviation. When international air travel became more and more present (1947) there was a need have international regulations. The ICAO counts 191 member states and all have to adopt their guidelines or advice the ICAO of regional differences, which will then published by the ICAO. ICAO is the International Civil Aviation Organization, a specialized agency of United Nations. It was created after the Convention on International Civil Aviation (the Chicago Convention) of 1944 was ratified in 1947. The purpose of ICAO is according to the convention: \"WHEREAS the future development of international civil aviation can greatly help to create and preserve friendship and understanding among the nations and peoples of the world, yet its abuse can become a threat to the general security; and WHEREAS it is desirable to avoid friction and to promote that co-operation between nations and peoples upon which the peace of the world depends; THEREFORE, the undersigned governments having agreed on certain principles and arrangements in order that international civil aviation may be developed in a safe and orderly manner and that international air transport services may be established on the basis of equality of opportunity and operated soundly and economically; Have accordingly concluded this Convention to that end.\".

write two paragraphs on the polices to reduce income inequality and poverty. Explain the content of these policies and make a comparative assessment.! Solution Poverty is of two type-primary and secondary. In the former people face lack of resource and wealth to meet up the subsistence. On the otherhand, the later is one where people face impediment to have command and control over his rights. Former one is more severe. To reduce that many policies could be taken. For instance reduction in umemployment. This mainly belongs to LDCs. Disguised, cyclical unempyoment is an acute phenomenon of LDCs. Hence, poverty can be reduced by providing the unemployed people a justified employment. Next, progressive taxation can also be prudential to redistribute wealth but whether that can actually happen in reality without any obstacle or not is questionable as rich tax payers will not be too happy with it and even they are sources of finance of politics. When politics enter into cost- benefit analysis economy gets distorted from his efficient point. Most important point is to give benefits to poor, viz. subsidy, rationing etc. Even they can be provided minimum wage programme for specific time, viz. MNREGA in India. Lastly, in many cases producers exploit labourer. Hence, by implementing minimum wage law this can be cure out. Inequality refers to the unequal distribution of wealth among people. Payment must be equal to marginal product ensures inequality in the economy. But there should be a certain upper bound to that, beyond that it can be boomerang for the economy and it can act as an obstacle to growth. To reduce this progressive tax is an important tool. Taking wealth as a form of tax and redistributing that via expenditure for a certain group or for all reduce the inequality. Providing employment programme, implementing minimum wage laws, benefits in kinds, levying direct and indirect taxes on certain commodities can be effective to redistribute the wealth and reducing poverty. Inequality and poverty are to some extent overlapped and complements of each others. Hence, targetting to reduce one can be fruitful and its effect can tricle down to the other as a bless. Normative economics support the above views with no doubts but implementation of it in practice in many times often become difficult due to self centered persons, politics, social and emotional reasons and so on..

What single , unique characteristic of a protist would be considered most animal - like ? Fungus - like ? Plant - like ? Solution Kingdom protista iis the most diverse group of eukaryotic organisms. They exhibit most diverese forms of obtaining nutrition, movement etc. Like animals, protozoan protists, do not make their own food, rather they obtain food from their environment. Thus they are heterotrophs, that move around and obtain food. Like fungus, protists occur in both unicellular and multicellular forms, feeding on decaying organic matter, and reproducing by forming spores. Also,some protists resemble plants and algae as they are autotrophs and they produce their own food. Presence of chloroplast have been found in some species of protists..

What are the indications that Sarcodina, Apicomplexa and Ciliophora may have been derived from ancestral Phytomastigophorea? Solution Normally Phytomastigophorea is composed of species such as \"phytoflagellates\" in which these species have associated with presence of chloroplasts so that they are photosynthetic. Sarcodina have some ancestral indications similar to that of Apicomplexa and Ciliophora & related to species in Phytomastigophorea, mainly Sarcodina, Apicomplexa and Ciliophora are lacking, mitochondria and some of them have \"photosynthetic pigments\". Some of the cilipohornas are associated with cilia where species of Apicomplexa have parasitic nature similar to Phytomastigophorea.

Tiktaalik roseae (fishapod) is a transitional fossil showing the evolutionary progression of fish to amphibians. Which of the following must be true? A. It must retain some traits found in its fish ancestors B. It must have new traits found in amphibians, but not found in its fish ancestors C. It must appear younger in the fossil record than its fish ancestors D. Only A and B E. A, B, and C Solution The answer should be D (which includes A & B ) because Tiktaalik shares anatomical features with both primitive fish and the first tetrapods. At first glance, it has features we readily associate with fish: fins, scales, and gillsTiktaalik\'s head and body are flat with eyes on the top of its skull, more like a crocodile than most fish. Its shoulders are not connected to its skull, giving it a functional neck, a feature which fish lack. And it has ribs like some of the earliest tetrapods which were used to support the body and aid in living and breathing on land. These features in Tiktaalik show that many of the body features we associate with the earliest tetrapods actually evolved in fish first..

Some grains of ferrite in yourphotomicrograph appear larger than others. Can you give onereason for this? There are two main reasons. Solution Two main reasons according to me 1. Due to heat, These grains got recrystallized and refined due to which grain growth takes place and hence becomes larger in grain size which accounts for ductility of Ferrite. 2. May be during deformation due to dislocation movement these grains were near the grain boundaries and got unaffected by the deformation..

Part A Problem and Program Details: As a part-time blog writer for a major sports network you are tasked with providing a readerfriendly summary of the most recent Winter Olympics. This will be an integral part of an article that will be used to discuss the next Olympic Games. Given detailed results from the Winter Olympics, which were provided to you by your supervisor, you are asked to summarize the medal standing for all participating countries. Your input data, which is provided in the olympics.mat file that can be downloaded from the eClass/Moodle, includes the following variables: - countries, which lists countries that scored medals. The countries are coded using three letter abbreviations, e.g., CAN stands for Canada. We use country code XXX to denote a case where two countries received the same medal (silver) in the same sport, i.e., there was a tie. - gold, silver and bronze, which list the countries that received gold, silver, and bronze medals, respectively. Note that the gold, silver and bronze variables list the data in the same order. This means that the i th row in these variables gives the countries that received the corresponding three types of medals for the same sport. Your objective is to convert the results per sport (from the olympics.mat file) into a table that lists medal counts and total medal tally per country where countries are sorted alphabetically. Note that countries variable already lists the countries alphabetically. You should also show the best performing country (or countries in case of a tie), when scored on the total medal tally and the number of gold medals. Moreover, you are required to list the countries that have 20 or more medals. The results should be printed to the Command Window using a specific format shown below. Part B There will be no submission of a file, we will be further testing the functionality of your program with another version of the olympics.mat file which contains more data that the initial version. Please download the olymics.mat file from eClass under assignment 4B and re-run your solution. Code Requirements: 1. You must use three sub-functions: the first that will compute number of gold, silver, and bronze medals per country; the second that will print the table with medal standings; and the third that will compute and print the best performing countries. The third sub-function should be called three times; each time for a different criteria of performance (most medals, most gold medals, and at least 20 medals). 2. Your primary/main function assignment4 should have the following outline: function [] = assign4_() %load olympics.mat file load(\'olympics.mat\'); % compute medals for each country using a sub-function that is % called using a loop over all countries % display medal counts for all countries using a sub-function % display countries with most medals, most gold medals, >=20 medals % using a sub-function, the same sub-function should be used 3 times end %this end termina.
