Insturmental Chemical Analysis: What is the difference between the absorption spectra of inner transition elements (the lanthanide and actinide series) to transition metals? What molecular process is responsible for the absorption of UV/Vis radiation for these elements/ compounds? Which ones are more sensitive to environmental perturbations and why? Solution The difference between Transition Metals and Inner Transition Metals Molecular process responsible for the absorption of UV/Vis radiation for these elements/ compounds Inner transition metals are more sensitive to environmental perturbation because their transition band gaps are low. Formed bonds by inner transition metals with other elements also happen weaker in comparison to transition metals..

Aiom for the ADT List. C++ Explain what this pseudocode is doing. aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1) Solution You have a list and we know list has index starting from 0, 1,2,3,4,5,6,..... So (aList.insert(i, item)): Inserts item at index i (aList.insert(i, item)).getEntry(i+1) : Inserts item at index i and fetches and returns the element at index i+1 aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1) So, it means (aList.insert(i, item)).getEntry(i+1) Inserts item at index i and fetches and returns the element at index i+1 and assigns it to element at index i..

an encryption scheme distributes randomly over the Ascii characters 32-127 What is the 8-bit entropy?? Solution An encryption scheme we use must convert plain text to human readable cipher. We here convert 32 ASCI to 127 character. The transmitter send the message through the channel.The channel modifies the message in some way.Then the receiver then finds which message is send.The probability expected value of the information contained in each message is called entropy .The 8 -bit entropy is mostly used for finding the value..

A class has 40 students aged 17 to 34. What is the probabilty that at least two students are the same age? Why? Solution Here we have that P(atleast two same ages )= 1- P(no same age) Now total favorable cases for no same age are 34-17= 18 ( as all will be of different ages) Thus Probability ( different ages ) = Total favorable case/total case =18/40 And accordingly Probability (atleast two same ages ) =1-18/40 = 22/40 = 11/20 So last required answer is 11/20..

A microbial geneticist isolates a new mutation in E. coli and wishes to map its chromosomal location. She uses interrupted-mating experiments with Hfr strains and generalized-transduction experiments with phage P1. Explain why each technique, by itself, is insufficient for accurate mapping. Solution Hfr cells undergoing conjugation transfer host genes in a linear fashion. The genes transferred depend on both the Hfr strain and the length of time during which the transfer occurred. F factors arise from improper excision of an Hfr from bacterial chromosome. They can have only specific bacterial genes on them because the integration site is fixed for each strain. P1 does not recognize pseudo-pac sites on the chromosome. P1 seems to begin packaging from random double-stranded breaks on the chromosome that are generated during phage infection. Generalized transduction is the process by which any bacterial gene may be transferred to another bacterium via a bacteriophage, and very rarely a small number of phages carry the donor. A restricted set of genes will not be able to transfer by this method. She wanted to transfer a specific gene to a specific located which is not doen by generalized transduction, so accurate gene mapping will be difficult by these methods..

1)Please explain the commands ifconfig, ping, traceroute, netstat, dig, nslookup, route, host, hostname. 2). Explain briefly about TCP/IP and its Protocol Architecture. 3) Explain the difference between TCP/IP Protocol stack and OSI model. Solution Answer: 1) Ipconfig Ipconfig is an MS-DOS utility that can be used from MS-DOS and an MS-DOS shell to display the network settings currently assigned and given by a network. This command can be utilized to verify a network connection as well as to verify your network settings. Ping Ping is one of the most commonly used network commands that allows you to ping another network IP address. Pinging another address helps determine if the network card can communicate within the local network or outside network. Netstat The netstat command is used to display the TCP/IP network protocol statistics and information. Nslookup The nslookup MS-DOS utility that enables a user to do a reverse lookup on an IP address of a domain or host on a network. Route The route MS-DOS utility enables computers to view and modify the computer\'s route table. traceroute The tracert command in MS-DOS and Windows (known as traceroute in Unix-like operating systems) is a useful tool for diagnosing network issues. It allows you to view a listing of how a network packet travels through the network and where it may fail or slow down. Using this information you can determine the computer, router, switch or other network device possibly causing your network issues. host solves a host name into an Internet Protocol (IP) address or an IP address into a host name. the hostname command is used to show or set a computer\'s host name and domain name. It is one of the most basic of the network administrative utilities. A host name is a name that is assigned to a host (i.e., a computer connected to the network) that uniquely identifies it on a network and thus allows it to be addressed without using its full IP address. Domain names are user-friendly substitutes for numeric IP addresses. The basic syntax for the hostname command is hostname [options] [new_host_name] 2)TCP/IP protocols map to a four-layer conceptual model known as the DARPA model , named after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA model are: Application, Transport, Internet, and Network Interface. Each layer in the DARPA model corresponds to one or more layers of the seven-layer Open Systems Interconnection (OSI) model. Network Interface Layer The Network Interface layer (also called the Network Access layer) is responsible for placing TCP/IP packets on the network medium and receiving TCP/IP packets off the network medium. TCP/IP was designed to be independent of the network access method, frame format, and medium. In this way, TCP/IP can be used to connect differing network types. These include LAN technologies such as Ethernet and Token Ring and WAN technologies such as X.25 and Frame Relay. Independence from any specific ne.

At what point does commercialization start to create inequality? Please provide examples. Solution Markets and commerce change the character of the goods they touch.Such deliberations touch, unavoidably, on competing conceptions of the good life.For fear of disagreement, we hesitate to bring our moral and spiritual convictions into the public square.It simply means that markets will decide them for us.At a time of rising inequality, the commercialization of everything means that people of affluence and people of modest means lead increasingly separate lives. We live and work and shop and play in different places. Children go to different schools. It’s not good for democracy, nor is it a satisfying way to live.Democracy does not require perfect equality, but it does require that citizens share a common life. What matters is that people of different backgrounds and social positions encounter one another, and bump up against one another, in the course of everyday life. For this is how we learn to negotiate and abide by our differences, and how we come to care for the common good. The public schools are an integral part of the institutions of democracy. By schools, Human Capital forms which eventually helps a country to faster its growth and substantially move forward.If we are to achieve the democratic ideal of equity, there must be a commons, and it must be accessible for all to participate effectively. Public education is an important part of that commons. But this common education is not fee, and only those can grab this oppurtunity who are able to pay for it.Commercialization encloses the commons and puts up fences, with admission only to those who can pay. It privatizes public space. It makes the dollar, not citizenship, the entry point to educational experiences and social and political influence in a democratic society..

A benefit of an activity received by people not participating in the activity is called a(n) Solution Assuming the question is in terms of economics, the answer is Positive Externality Externality is a phenomena in which a proportion of cost (negative externality) or benefit (positive externality) an activity is received by someone who did\'t participate in the activity. In case a cost is incurred it is termed as negative externality, while in case of benefit is received, it is termed as positive externality. Consider education - a learning activity, in an underdeveloped country. In poor area, if there is an initiative of education, and children are educated by any welfare institution or government, that education would not only affect the child individually, but also would affect his family in a positive manner. The household people might learn somethings which they didn\'t knew before, that can save them in many ways, such as importance of hygene like washing hands before having food, or caring for mortals, etc. This is the case of positive externality, as even though the adult didn\'t attend the education, they did received the benefit. Education also reduces crime, and hence society as a whole benefits. Another examples of positive externality are low income people who do not pay taxes does recieve state welfare, military-defence protention, and enjoy many other public goods, like street light, roads, etc. The opposite of positive externality is negative externality. Suppose a polluting industry is placed in a poor agricultural area, and it will pollute the land and or water and or by dumping wastes and smokes of byproducts. People who don\'t work and have no relation to the industry would also be affected in an adverse manner. Yet some proportion of the population now have more stable income, but many others who didn\'t participate in the activity are affected. Farmers doing pisciculture and agriculture would be affected by dead fishes or bad crop, or general public breathing polluted air would incur several health cost. All kinds of pollution which are not natural (like pollution by volcanic eruption), are examples of negative externality..

You are given a specification for some Java classes as follows. A building has a number of floors, and a number of windows. A house is a building. A garage is a building. A room has a length, width, a floor covering, and a number of closets. You can never create an instance of a building, but every object that is a building must have a method that calculates the floor space, i.e., the Building class is abstract, and has an abstract method. A house has a number of bathrooms, and an array of Rooms. A house has a method that returns the average size of the Rooms. A Garage can hold some number of cars, and it may have a cement floor or a gravel floor. A garage has a length and a width. (Don’t use the Room class as a member of the Garage class.) Object / \\ Building Room / \\ House Garage 2. Implement the specification. You must use the following mechanisms correctly: · Inheritance – is a · Composition – has a · Constructor methods · Accessor / mutator methods = getters, setters · Arrays of objects · Passing arrays of objects to methods · Abstract classes and methods · Access modifiers – public private o might not need protected, a you should never use · toString() methods · the super keyword · method overriding · interfaces · generics are introduced · polymorphism using inheritance, and interfaces Include a test class that has a main method. This test program will make instances of your classes and output the text representation of the objects using the toString() methods. There should be enough comments in the output so that it is easy to see which classes are being tested. In your test class, create an ArrayList. Add a couple of houses and garages to your list. Loop through the list, using the enhanced for loop. Print out the objects using the toString methods. (The toString methods should return a String object containing all of the instance variables’ values.) Additional Requirements: Only methods used for testing will call the System.out.println() method. The purpose of the classes is to store and manipulate data. Input and output is not included in the data storage and manipulation classes. A house will calculate its floor space by looping through the array of rooms, and accumulating the floor space. Don\'t worry about the space used by a closet, you can assume that it is included in the size of the room. Work incrementally. Start by making a Room class, and testing it. Then make the Building and Garage classes, test them. The make the house class, and test it. The constructor for the house class has an array of rooms as a parameter. The building class is the only class that stores and manipulates the number of windows, and number of floors. All garage objects have exactly one floor. Perhaps the Building class should have an overloaded constructor to accommodate this. Interface Add an interface to your package. Call the interface MLSListable. That means that a class that implements this interface is a property that can be listed for sale. T.

8. Would the following cell have a spontaneous reaction? Explain. Solution A redox reaction is spontaneous if the standard electrode potential for the redox reaction, Eo(redox reaction), is positive. Eo(redox reaction) = Eo(reduction reaction) + Eo(oxidation reaction) and Eo(redox reaction) > 0 that is, Eo(redox reaction) is positive If Eo(redox reaction) is positive, the reaction will proceed in the forward direction (spontaneous). Spontaneous redox reactions can be used to produce electricity (see galvanic cells (voltaic cells)).If Eo(redox reaction) is negative (Eo(redox reaction) < 0), the reaction will not proceed in the forward direction (non-spontaneous).This reaction will be non spontaneous redox reactions cannot be used to produce electricity. E standard potential value is positive so reaction is non spontaneously.

Write a program that mimics the operations of several vending machines. More specifically, the program simulates what happens when the user chooses one of the vending machines, inputs money and picks an item from the vending machine. Assume there are two vending machines: one for drinks and one for snacks. Each vending machine contains several items. The name, price, and quantity of each item is given in two text files; one named “drinks.txt” for the drinks vending machine and the other named “snacks.txt” for the snacks vending machine. The format of the input values is comma-separated. The items listed should be organized in the file with the following order: name, price, quantity. Here are some example items: The actual reading and parsing of the input file is already handled in the class supplied to you (see code on BlackBoard). You are given the variables as individual values. You will need to create the .txt files for creating and testing your vending machines. You will need to create/complete three classes for this homework assignment: Item, VendingMachine, and VendingMachineDriver. Problem Description Milk,2.00,1 Within your VendingMachine class, include these methods: VendingMachineThisconstructormethodwilltakeinthenameoftheinputfileand create a vending machine object. A vending machine object will contain an array of Item objects called stock and an amount of revenue earned. This constructor method has been completed for you and should work appropriately once you have completed the rest of this class and the other class definitions. vendThismethodwillsimulatethevendingtransactionafteravalidamountofmoney and an item selection are entered. This method will decide if the transaction is successful (enough money or item) and update the vending machine appropriately. outputMessage This method will print an appropriate message depending on the success of the transaction. If the user does not have enough money to buy the chosen item, the vending machine should prompt the user to enter more money or exit the machine. If the vending machine is out of the chosen item, the program will print an apology message and prompt the user to choose another item or exit the machine. If there is enough money for the item selected, then the vending machine will give the user the item and return the change. printMenuThismethodprintsthemenuofitemsforthechosenvendingmachine. The Item class needs to include the following data variables: • description as a String • price as a double • quantity as an int Within your VendingMachineDriver class, include a main method as the starting point for your solution that creates the vending machine objects appropriately and then use a loop that continues interacting with the vending machines until the user enters “X” to exit. See the sample session for details. As you implement your solution, you might find that some methods contain some repeated coding logic. To avoid unnecessary redundancies in your code, have these method.

Chapter 2 Supplemental Case Xerox Focuses on HR Xerox is a widely known firm worldwide, but it has been through numerous crises in the past decade. In fact, at one point several years ago, there were questions about Xerox surviving as a firm. But no longer. Under the leadership of Anne Mulcahy as CEO, Xerox has rebounded Numerous strategic business and financial decisions had to be made, including reducing the workforce by 30,000. But Mulcahy also stressed that HR had to become a more strategic contributor One of the actions taken was to consolidate a number of HR fu and has added Internet-based systems to make HR services more accessible to nctions from different business into a corporate HR Service Center. This center performs many administrative transactions managers and employees To track employees\' views on the company and HR, employee surveys on the company intranet have been used for several years. Areas at which lower scores were recorded have been addressed by HR staff and other managers. The survey results have led to another primary focus at Xerox: employee retention. With all of the reductions and organizational restructurings, keeping the remaining employees, especially high-potential ones, has been a continuing emphasis. Xerox has invested significant time and resources into training and development of its employees, an important retention factor. Greater use of e-learning, technology, and leadership development have paid off in reducing turnover and convincing employees that career opportunities exist at Xerox. Continuing competitive pressures are presenting new challenges for Xerox and its HR staff. The strategic importance of HR has been demonstrated in the past and looks to be a part of the firm\'s future.4 Questions 1. Discuss the challenges faced by HR management when significant staff cutbacks occur and how they should be addressed 2. Use of technology, employee retention, and HR development have been at the core of HR becoming more strategic at Xerox. Why have those areas been so key? Solution 1. Challenges : A. Need of Restructuring of organization : organization needs to arrange and reallocate current employees. B. Investing time again : organization has to build trust with the employees again as not following up on this can lead to a negative workplace environment. C. An environment of suspense and distrust: employees feel less belonged to organization and doubt that they might get laid off from the job as well. D. Costs to train and develop new employees : since new or existing employees would be required to Take up some jobs, costs are bound to occur..

which of the following is true according to the proposition that music is a human phenomenon? which of the following is true according to the proposition that music is a human phenomenon? which of the following is true according to the proposition that music is a human phenomenon? Solution Ans- : The question of musical naturalness has increasingly often been the subject of lively debates within both natural and human sciences. In the present paper the issue is discussed primarily in terms of the propositions which accord with the contemporary naturalistic vision of a human and the world. One of the most important problems in this context is the opposition between a natural phenomenon and a cultural invention. Among the vast amount of different human achievements, some demand strenuous learning whereas other emerge spontaneously in all societies. The latter type of achievements is the result of the natural selection of human abilities. Recently, it has been hotly debated whether or not music is a biological adaptation. If it is, musical abilities should give an important advantage to individuals. There are numerous examples of the possible advantages. Namely, the music abilities play an important role in the enhancement of bonding between the mother and her infant child. Moreover, they are salient in the indication of fitness during sexual display. The abilities are also vital in the consolidation of a group during social music performance as well as in the transmission of information about the stability and cohesion of the group. If musical abilities are indeed a vital form of adaptations, they may imply some further questions such as the existence of music-specific abilities and of musical universals, as well as the distinction between music understood as art and music understood as universal communication (like language). All these issues have different methodological consequences for the shape of musicology as a discipline of science. These are, among others, pre-empting Europocentrism in research, the possibilities and extension of the use of comparative methods in ethnomusicology, the scope and applicability of the interdisciplinary studies based on the reductional structure of knowledge. The dispute over musical naturalness dates back to the beginnings of reflection on music and has attracted an almost countless number of stances, including those which ascribe to music a number of universal natural laws and others which treat the musical products of man as phenomena wholly independent of the world of nature. Yet while up to the beginning of the twentieth century, due to our limited knowledge about the nature of human behaviour, all proposed solutions to this dispute still remained necessarily in the realm of speculation, in recent years, thanks in particular to rapid progress in the natural sciences, the question of the naturalness of music has begun to enter the scope of sciences with ‘hard’ methods of verifying knowledge.

What is synchronous messaging and asynchronous? Solution Synchronous Messaging : asynchronous Messaging : In asynchronous messaging there is no wait for the reponse for the message transmitted. both the systems symultaniously transmit the data and do not wait for any kind of respose of the recepient for the communication sent. Email is the most common example for asynchronous messaging. Asynchronous message passing allows more parallelism communciation to multiple systems without any blocking for response from the recepient. But the disadvantage is primarily on the loss of info as there is no response communciation form the recepient for the data receievd and can lead to delivery of incomplete data..
