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..

SQL for Data Analytics: Mastering Queries and Reporting with TrainingUncodemy
SQL (Structured Query Language) is a strong database management and manipulation tool. It enables you to interact with the database, access and change data, do sophisticated computations, and generate informative reports.
Indexes are used to expedite the query execution time without which the pointer would traverse from the first row till the last entry of the table/view to notice the relevant row. Larger the database (table), more is the cost of execution. However, if the index is already set, irrelevant entries are skipped, thus advancing the search.
Describe the three ways in which protists can move. Provide an examp.pdfirshadkumar3
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 bloo.pdfirshadkumar3
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..

A 15 (ww) solution of BaCl2 in water has a density of 1.12 gmL..pdfirshadkumar3
A 15% (w/w) solution of BaCl2 in water has a density of 1.12 g/mL.
What is the concentration of the same solution expressed as molarity? How many moles of
chloride ions are in 25.0 mL of the BaCl2 solution?
Solution
Molarity = (% w/w x d x 10 / MW)
Molarity = (15 x 1.12 x 10 / 208.23)
Molarity = 0.807 M
moles = Molarity x V in L
moles = 0.807 x 25/1000
moles = 0.0202.
Use the Internet to research one of the four modes of transportation.pdfirshadkumar3
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 segmentedA.annelidsB.planariansC.rou.pdfirshadkumar3
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 dis.pdfirshadkumar3
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.pdfirshadkumar3
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 t.pdfirshadkumar3
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.pdfirshadkumar3
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

Compare and contrast the main approaches for developing a WBS. Which.pdfirshadkumar3
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..

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. Skills

How do you do the last page. How do you make the picture with the t.pdfirshadkumar3
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.pdfirshadkumar3
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..

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

what are the best way to query optimization in MYSQL.SolutionT.pdf
1. 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.
