what are the best way to query optimization in MYSQL. Solution The best way to query optimization in MYSQL is as below. 1.INDEXES:It behaves as a pointers to row of a table. MYSQL permits us to index data tables.computing the index to a table is nothing but calling the CREAYTE INDEX command ,defining the feilds to index.nearly 16 indexes is possible for a table. Additionally the MYSQL assiststhe multi column indexes and full text search indexes. Additionally to query optimization in MYSQL. 1.Optimizing the query perfomance:during the examination of query perfomance,it is in service to review the EXPLAIN keyword. it is kept before a select query ,tells how MYSQL aims to execute the query and rows required to process . 2.Modifying the internal variables: MYSQL is much open and reasonably simple additonally fine-tune its default settings to get high perfomance and stability..

Describe the three ways in which protists can move. Provide an example of a protist that uses each type of motion. Solution The three ways in which protists can move are by using 1. Cilia :-Cilia are tiny hair like projections that extend from their surfaces or from within the cell. Cilia enable protist to move in rhythmical fashion as they swim through the water. Cilia also helps protist to capture food. Example - Paramecium 2. Flagella - These are long, whiplike structures. Protist can have one or more flagellar structures.Flagella help protists move staedily through currents and waves Example- Giardia 3. Pseudopodia- Thsi is another type of locomotion.Protist moves by extending its body forward and then pulling rest of the body forward as well. The finger-like structure which the protist project forward is called pseudopod. Pseudopod is also used to trap food. Example - Amoeba.

A woman with type O blood gave birth to a baby, also with type O blood. The woman states a man with type AB blood was the father of the baby. The antigen determining gene for blood type has three alleles I^A, I^B, i. a. How many phenotypes are possible? b. How many genes play a factor in this phenotype? c. How is this example different from a typical Mendelian cross? What extension is displayed? d. Is there any merit to her statement? Why? Solution The mother has O blood group, thus i, i would be the genotype of the mother as blood type O is recessive. There are three genes that play a role in this cross. A parent of blood type AB has the codominant IA and IB alleles. When the parents would mate , there would be IA , IB crossing with i. As a result , out of the four offsprings , two will contain IAi and two would contain IBi genotype, I.e. Half of the children would have type A and half would have type B blood group. For a woman with O blood group, the father should also have O blood group. Thus there is no merit to her statement..

Use the Internet to research one of the four modes of transportation, and describe its impact on the transportation industry. In addition, explain how the mode of transportation was selected, and compare it to the other three modes not selected Solution There are different modes of transportation like air, water and land transportation. some others like pipelines, cable and space transportation etc. Generally transportation is used to move people, animals, and other materials from one place to other. every mode of transportation has its different impact on the transportation industry. HERE I AM GOING TO DISCUSS THE IMPACT OF AIR TRANSPORTATION ON TRANSPORTATION INDUSTRY: Air transportation is one of safest and most efficient means of transportation, it covers whole nation and internation distances. Just because of this mode, global trade is possible and one can live in other countries. * it provides worldwide transportation network, which helps in global business and tourism. * air transport adds 40% of export of goods in total value of export. 40% is very huge amount. and it automatically adds to GDP of country. * Travel system allows intercontinental travel to large volumes of the passengers & cargo in short periods of time. * The air transportation mode is vital for the growth of the business and industry in the community, providing air access to companies that are must to meet the demands and supply, competition & expanding marketing areas. * those Communities which do not have airports or some sufficient air services, have limitations placed on the capacity for the economic growth. NOW I AM GOING TO DISCUSS SOME POINTS REGARDING WHY AIR TRANSPORTATION IS PREFFERED OVER OTHER TRANSPORTATION: * It is the fastest and unbroken mode of transportation as compared to other modes. * No doubt it is one of the most expensive mode but its rapidity characteristics has overcome this limitation. * as compared to other modes, it is more comfortable, efficient and quick service. * one of the most point is that, this mode does not require any investment in construction of any tracks and paths as it is very much required in other modes. * their is no physical barrires while execution of service..

Which of these worms are segmented? A.annelids B.planarians C.roundworms D.flukes E.All worms are segmented Solution Choice A iscorrect. Reason: Phylum annelida represents worms with segmented body. They also have radial symmetry and small segments can be found on their body. These segments are true segments in nature which means that external segment corresponds to internal segmentation. Further, the ventral parts of these segments also contain pseudopodia in some annelids. Thus, annelids represent true segmented bodies such as in earthworm..

What are the proteins involved in this functions?? In lecture we discussed the process by which cells migrate, which includes protrusion, attachment, translocation, and detachment. Please do the following in the space below: 1) draw you own version of Fig 14 - 27 (label the lamellipodia, filipodia, points of adhesion, direction of movement), 2) label each of the 3 steps represented and describe (in your own words) what happens at each step, and 3) list the proteins involved in each step and describe (in your own words) what those protein are doing. Solution The protein involved in each of the above step and its functions are-: 1.Protrusion step i) Arp 2/3 - It is a heptamer protein that attaches itself to the side of a pre existing actin filament and then nucleates de novo actin polymerisation at a fixed angle. ii) Actin - Multiple functional protein involved in protein - protein interaction. iii) Cofilin - It is an actin - filament serving protein helps in actin polymerisation. 2. Attachment step i) Integrin - Adhesion to the substratum occur mainly via Integrin. ii) Paxillin and FAK - The two important signalling proteins involved in adhesion. iii) Talin, vinculin and alpha actinin- These are the group of adhesion proteins link actin to substratum through integrin. 4. Translocation step i) Myosin II and dynein - These proteins controls translocation step. 4. Detachment step i) Actomyosin - This protein is the combination of actin and myosin involved in contraction that exert force against adhesion results in detachment..

Using Social Media to Tell the Story of TOMS TOMS offers more than a comfortable and trendy pair of shoes. It is about status and a story to tell. Mycoskie realised the power of the TOMS story since the early days of the company and has focused on it ever since. Mycoskie wrote in his book, acknowledging Kendall Haven, who authored Super Simple Storytelling: \"Human minds rely on stories and story architecture as the primary road map for understanding, making sense of, remembering, and planning our lives - as well as the countless experiences and narratives we encounter along the way.\" He added that smart, future-oriented companies use this ancient impulse in new ways, by telling stories that people can watch on YouTube and share on Facebook. He quickly realised the strength of social and digital media to convey his story by saying: \"People are no longer all listening to or watching the same few radio or TV stations each week - they\'re following their own carefully curated Twitter feeds, commenting on and creating blogs, channel surfing among more than 500 TV stations, watching Hulu on laptops, clicking on YouTube, reading Kindles and Nooks, and surfing on iPads.\" In 2009, Mycoskie partnered with AT&T by filming a commercial, which ran throughout 2009 and was an enormous success. The commercial profiled TOMS as a for-profit company that donates one pair of shoes to a child in need for every pair purchased, and founder Blake who uses his AT&T BlackBerry to conduct business from around the world. Lots of people tweeted about the commercial creating awareness about TOMS and AT&T, and support for the TOMS business model. 1- Discuss in your opinion, does business responsible for its society wellbeing or just making profit? Why? 2- How TOMS shoes utilizes the CSR in its marketing activities? Solution The traditional goal of firm is profit maximisation. The US supreme court in Dodge vs Ford motors Co has come to the view that profit maximisation for owners should be preferred. But this view is not given that much importance today. Today corporates are being viewed as responsible to society. Infact research has revealed that 55% customers were ready to purchase products of company at higher prices provided it engaged in CSR. So these goals are not mutually lay exclusive. Dodd had rightly said business organisation is an economic institution which has social service as well as profit maximisation function 2 Tom\'s shoes utilises CSR in its marketing activities. It is saying that it will donate one pair of shoes to the deserving for every pair of shoes it sells. In this way it is appealing to the social conscious individuals and showing them that it is contributing to the cause of society and is not just interested in profit making.

The functions f_1, f_2, ..., f_m defined on the interval I are said to be linearly dependent on I if at least one of them can be expressed as a linear combination of the others on I. Equivalently, they are linearly dependent on I if there exist constants c_1, c_2, ..., c_m, not all zero, such that c_1 f_1 (x) + c_2 f_2 (x) + middot middot middot + c_m f_m (x) = 0 for all x I. Otherwise, they are said to be linearly independent on I. Show that the functions f_1 (x) = e^x f_2 (x) = e^-2x f_3 (x) = 3e^x - 2e^-2x are linearly dependent on (-infinity, infinity). Solution Given that f1(x) = ex , f2(x) = e-2x and f3(x) = 3ex - 2e-2x Then there exists non-zero constants C1 = - 3 , C2 = 2 and C3 = 1 such that C1f1(x) + C2 f2(x) + C1f3(x) = 0. Hence The functions f1( x) = ex , f2(x) = e-2x and f3(x) = 3ex - 2e-2x are linearly dependent for all x *( - , ).

Silica gel is slightly acidic. Will this cause an acidic compound to run faster or slower in a given mobile phase vs a similar basic compound? Why? Solution SiO2 is an acidic compound.when SiO2 in water gives acid H2SiO3. In acidic or basic condition, mainly depends upon polarity. Polar compounds easily hydrogen bonding with silica gel and make highly mobile phase polar. Polar.compounds bind with silica gel easily whereas nonpolar compounds easily will come in the column chromatography..

Compare and contrast the main approaches for developing a WBS. Which approach do you feel is most user-friendly? Explain your answer. Solution The main approaches for WBS development are as follows: 1. Deliverable based approach: The project team works as per the functional components of the products. Here the process are compiled and accomplished as per the elements that constitutes the complete project. 2. Task Based: The tasks to create the project deliverable are first identified and are prioritized. This is also known as verb based method. 3. Time based: The projects are divided as per the completing and delivery time so that the projects that are to be delivered first can be worked upon by the team. 4. Cost based. The project is defined in terms of cost. The following methods are used for developing a WBS: 1. Top-Down Approach: The steps involved in the top-down process are as follows: This approach is appropriate when the project members are greenhorn to WBS development and the project\'s nature is complex and ambiguous. 2. Bottom-Up Approach: The steps involved in the bottom-up process are as follows: This method is applicable when the nature of the project, project scope, and life cycle is clear. Bottom-up method is more user friendly as the appropriate templates and organizational standards are available..

***please help! READ the grading criteria*** HW5: Weekly Timesheet CSS 161 Fundamentals of Computing By: Hansel Ong Summary In HW3, you created a program that allows the user to enter time worked on a week-by-week basis Such a system calculated any hours worked over 40 hours a week as overtime. However, this means that an employee could work 12 or 20 hours once a week, 4 hours the rest of the week, and not be paid overtime at all. Let\'s fix this problem in this homework. For simplification, let\'s limit the number of weeks the user can enter to two weeks maximum. Note also that any hours worked in a day beyond 8 hours should be regarded as overtime hours. Estimated Work Needed This assignment took me about 30-45 minutes to write (not including challenges, but including testing, commenting, and cleanup) in less than 200 lines of code In other words, you should expect to spend between 135 to 450 minutes working on this assignment. If you\'ve spent more than 7.5 hours working on this assignment, then you are likely struggling with loops and/or arrays and should re-read the lecture slides and attempt the exercises within seek help from your fellow classmates, myself, your lab instructor, QSC tutor as well as online resources.

In 1972 the small kingdom of Bhutan, in Asia, developed a measure of output that included “Happiness.” In class we also saw that former Senator Robert F. Kennedy criticized GDP for its inability to take into account the quality of life of a nation’s citizens. In 2013, President Obama has appointed you to look into developing a new measure of the nation’s overall economic wellbeing called the Gross Domestic Happiness Indicator (GDHI). What would you include in this new measure and how will you incorporate existing measures of GDP into the GDHI? Solution Ans I will include Gdp per capita, measures of social support, life expectancy at birth, corruption and nepotism, freedom to choose,pollution, public goods, environmental goods in thus measure. Gdp per capita is the existing measure that I will utilize..

How do you do the last page?. How do you make the picture with the trail. I\'ve coded everything but that need help with how to change the numbers in the matrix to produce the correct trail. Coded in C please. How Do u code the function ask of on the last page? CS 100 Project Six-Fall 2016 Project Ovenicy: The world is not flat, despite what the Flat Earth Society hupsLAww:a.theflatearthsociety.org) says. There are lots of hills and valleys out there. Given this, mankind has spent considerable time and effort measuring the exactelevation above sea level for each on the earth You can view these elevation maps as a two- dimensional grid. A sample elevation shown below: 100 110 120 105 115 100 105 115 110 100 105 115 95 120 120 98 95 110 125 130 135 100 110 120 130 135 145 Obviously, elevations get higher in the mountains, and approach zero as you near the ocean. This program reads a set of elevation data and: 1. Generates a simple image from this clevation data, a black-and-white image where higher clevations have a darker shade than lower elevations. 2. Identifies a path across this grid. The path can be North-to-South, South-to-North, East-to-West, or West- to East. To find this path, you vant to minimize your clevation gain (climb). In other words, you don\'t want to walk uphill any more than necessary. Instead, you want to go as much as possible, a steep downhill path is viewed as optimal. You will generate a second image file with the recommended trail. To generate a black-and-white (grayscale) picture of this elevation data, we will use a graphics format that uses ASCII (text files. Most graphics programs use binary files (gif,jpeg, etc) which promote smaller fle sizes. Since this is just CS 100, well stick with ASCII (text) files, even though they take more space. The ASCII format we use is called pgm, and is shown P2 at the right. The first line is always P2. After that, you width inpix have three values (width, height, grayscale levels that pixels value (always 2SS for this project) maximum grayscale can be on a single line or separate lines. Finally, you pixel-11- intensity pixel-1-2-intensity pixel-1-3-intensity have the actual pixel values for each pixel in the image. pixel-2-1-intensity pixel2-2-intensity pixel-2-3-intensity A pixel with a value of 0 is black (absence of light and a pixel with a value of 255 is white (all light pielN-1 intensity pixelN-2- intensity pixel-N-3intensity This project involves taking a set of elevations and making a grayscale image from these elevations, and then drawing a second image that includes a trail across the grid. You are crcating two PEm images. Both of these images will use 255 as the maximum grayscale value (values range from 0-255) The first image is simply a map of the clevations. So that we can mark a visible trail on this map part two), we will map all the clevations in our input file to a value in the range of 55255. By doing this, placing a trail of color 0 (black) is easily visible o.

How do auditors gain an understanding of the internal controls in an IT environment? Solution The control environment is the foundation on which an effective system of internal control is built and operated in an organization that strives to (1) achieve its strategic objectives, (2) provide reliable financial reporting to internal and external stakeholders, (3) operate its business efficiently and effectively, (4) comply with all applicable laws and regulations, and (5) safeguard its assets. Most of the well-publicized failures (including not only Enron and WorldCom, but also the governance failures that led to the 2008 financial crisis) were, at least in part, the result of weak control environments. The control environment includes the following elements: • Integrity and ethical values. • Management philosophy and operating style. • Organizational structure. • Assignment of authority and responsibility. • Human resource policies and practices. • Competence of personnel. Central to any approach to auditing the control environment is the assessment of risks from failure of each one of the six individual control environment elements as defined in the glossary of the Standards. Upon determining the risks relating to each one of the six control environment elements, the chief audit executive (CAE) may consider including in his or her annual audit plan one or more failures can miss the fundamental aspects of the organization’s foundation..
