True / False 1. The primary difference, in terms of processing, between gray iron and ductile iron is that ductile iron has a very small addition of Mg or Ce added to generate nodules of graphite in the microstructure. 2. Ferrous based materials are sometimes limited in their use in a given application due to issues such as poor corrosion resistance, high density, and relatively poor conductivity. 3. Annealing is the exposure of a material to an elevated temperature for a short time period followed by quenching to room temperature at a fast rate. 4. Die casting is generally more capital intensive than sand casting and so is better suited for making high volumes of the same part. 5. Over-aging during precipitation hardening processing will result in a decrease in strength of the material. Solution 1.true(Nodule formation is achieved by adding nodulizing elements, most commonly magnesium and, less often now, cerium) 2.false( ferrous based materials have relatively high conductivity) 3.true(for copper, silver and brass can be quenched quickly at fast rate, where as for ferrous metals like steel slow cooling is required to anneal) 4.true( die casting needs more capital investment for casting equipments and metal dies) 5.false( over-aging during precipitation hardening process is done to increase the strength of the material).

Duplex 2209 Weld Overlay by ESSC Process
In the modern world of industrialization the wear is eating metal assets worth millions of dollars per year. The wear is in the form of corrosion, erosion, abrasion etc. which occur in the process industries like oil & gas, refineries, cement plants, steel plants, shipping and offshore working structures. The equipments like pressure vessels, heat exchangers, hydro processing reactors which very often work at elevated temperatures face corrosion in the internal diameter. Duplex 2209 weld overlay on ferrous material is developed for high corrosion resistance properties and having high productivity by Electroslag strip cladding process due to its less dilution ~10% as compared to SMAW , GTAW or FCAW process. Because of Low Dilution ~10% undiluted chemistry can be achieved with single layer as compared to other weld overlay processes. The facility was developed inhouse to carry out weld overlay by ESSC and Testing.
Heat treatment of Steel
The document discusses heat treatment processes for steel, including purposes, defects, and specific processes. It describes annealing processes like full annealing, subcritical annealing, and spheroidizing annealing. It also covers normalizing to increase strength compared to annealing. Hardening and hardenability of steels are discussed, noting that hardening involves rapid cooling to form martensite for maximum hardness, while hardenability refers to how deep within a steel piece martensite can form during quenching.
Diffusion bonding
Diffusion bonding is a solid-state welding technique that joins materials together through atomic diffusion without melting. It involves applying high pressure and moderate heat to join carefully cleaned and mated surfaces. Diffusion occurs in two stages - initial metal-to-metal contact formation followed by atomic diffusion and grain growth across the interface to form a complete bond. Various factors like temperature, pressure, time and surface preparation influence the diffusion rate. Common diffusion bonding methods include gas pressure bonding, vacuum fusion bonding and eutectic bonding. Diffusion bonding finds applications in the fabrication of components for industries like aerospace, nuclear and others.

ppt on Forging process
Forging is a metalworking process that involves shaping metal using localized compressive forces. It can be performed hot, warm, or cold. Forged parts range in weight from under a kilogram to 580 metric tons. Forging improves metals' strength and durability through grain refinement. There are several forging techniques including smithy forging (traditional hand forging), drop forging (using a hammer), press forging (applying continuous pressure), and roll forging (using opposing rolls). Forged parts generally require further processing to achieve their final shape. Common forgeable metals include carbon steels, aluminum, and titanium.
V5I9-IJERTV5IS090571
This document discusses the effects of heat treatment on the microstructure and mechanical properties of gray cast iron. It finds that hardening gray cast iron through quenching increases its hardness significantly compared to the as-received material due to the formation of martensite. Hardening and tempering gray cast iron results in a slight decrease in hardness compared to just hardening, as tempering allows some graphite flakes to reform. Microstructural analysis shows hardened gray cast iron has a martensitic needle-like structure instead of graphite flakes, accounting for the increase in hardness.

In bacterial chemotaxis, which feature of the bacterial flagella det.pdf
In bacterial chemotaxis, which feature of the bacterial flagella determines whether a bacterium is
in a run or tumble?
A. the shape of the flagella
B. whether the flagella rotate of move in a whip-like fashion
C. the speed of rotation of the flagella
D. the direction of rotation of the flagella
E. all of the above
Solution
E). All of the above
Flagella are the elongated motile structures of some cell surfaces, which are composed of
microtubules. They are needed for the locomotion of the organism. They consists of
microtubules arranged in 9+2 array. The microtubules slide along one another and produce
“whip-like” motion. When the bacteria is moving, we can detect by observing the flagella..

How exactly do Protease inhibitors help HIV patients fight the disea.pdf
How exactly do Protease inhibitors help HIV patients fight the disease?
Where exactly do quinolones act to prevent bacterial multiplication?
Cite 4 characteristics of an ideal antimicrobial agent
Solution
1.Enzyme that breaks down protein into its building blocks, amino acids, is called a protease.In
an HIV virus, proteolytic cleavage of the polypeptide precursors into mature enzymes and
structural proteins are catalyzed by HIV protease.HIV protease inhibitors are peptide-like
chemicals that competitively inhibit the action of the virus aspartyl protease. These drugs prevent
proteolytic cleavage of HIV Gag and Pol polyproteins that include essential structural and
enzymatic components of the virus. This prevents the conversion of HIV particles into their
mature infectious form.
2.Quinolones bind to a bacterial complex of DNA and DNA gyrase, blocking DNA
replication. Quinolones such as nalidixic acid bind to the cleavage complex composed of DNA
and gyrase during this strand passage. This interaction of quinolone acts to stabilize the cleavage
intermediate which has a detrimental effect on the normal DNA replication process. The effects
of this inhibition result in the death of the bacterial cell. The newer fluoroquinolones such as
ciprofloxacin, norfloxacin, and ofloxacin also interact with DNA gyrase and possess a broad
spectrum of antimicrobial activity.
3.solubility in body fluids-agent must dissolve in body fluids to be transported in the body and
reach the infectious organisms
selective toxicity-agents must be more toxic to microorganisms than to host cells.
toxicity not easily altered-agent should maintain a standard toxicity and not be made more or less
toxic by interactions with foods and other drugs or abnormal conditions such as diabetes and
kidney disease in the host
nonallergenic-agent should not elicit an allergic reaction in the host
stability-maintenance of a constant, therapeutic concentration in blood and tissue fluids, agent
should be sufficiently stable in body fluids.
Fred, Tom, Jenny and Sarah pooled their money and purchased a packet .pdf
Fred, Tom, Jenny and Sarah pooled their money and purchased a packet of jellybeans. Tom
received twice as many jellybeans as Fred while Sarah received tour less than Tom. Jenny was
given a third of the number of jellybeans that Sarah received. How many jellybeans did each of
the children receive if there were 40 jellybeans in the packet?
Solution
Let Fred has x jellybeans.so tom has 2x , sarah has 2x-4 , jenny has (2x-4)/3 jellybeans.since
they total have 40 jellybeans then
x + 2x + (2x-4) + (2x-4)/3 = 40
=> 3x+4(2x-4)/3=40
=>17x-16=120
=>x=136/17=8
so fred has 8,tom has 16,sarah has 12 & jenny has 4 jellybeans..
Explain the various categories of ratio analysis and provide example.pdf
Explain the various categories of ratio analysis and provide examples of at least two ratios in
each category. If you were an investor, which category would you be most interested in? Why?
Solution
Part-1
Ratios are used by lenders and business analysts to determine a company\'s financial stability and
standing.It\'s important to understand that financial ratios are time sensitive; they can only show
a picture of a business at a given time. There are five catagories of Financial ratios and those are
as follows :
Part-2 :
There are a large variety of ratios out there, but for an investor using financial ratios which are
broken up into four major categories: profitability ratios, liquidity ratios, solvency ratios and
valuation ratios. As an investor he should consider Profitability ratio because Profitability ratio is
a key piece of information that should be analyzed when you\'re considering investing in a
company. This is because high revenues alone don\'t necessarily translate into dividends for
investors unless a company is able to clear all of its expenses and costs. In general, the higher a
company\'s profit margin, the better, but as with most ratios, it is not enough to look at it in
isolation. It is important to compare it to the company\'s past levels, to the market average and to
its competitors.
Profitability Ratios : The profitability ratios are just what the name implies. They focus on the
firm\'s ability to generate a profit and an adequate return on assets and equity. They measure how
efficiently the firm uses its assets and how effectively it manages its operations and answers
questions like how efficiency his business and it helps to compare with other competitor.
Examples of Proftitablity ratios are Gross profit ratio, Net profit ratio, Operating profit ratio and
Return on investment ratio.
Market Value Ratios : The market value ratios can be calculated for publicly traded companies
only as they relate to stock price. There are many market value ratios, but a few of the most
commonly used are price/earnings (P/E), book value to share value and dividend yield .
LEVERAGE RATIO /Capital Structure ration : The term capital structure refers to the
relationship between various long term forms of financing such as debentures (long term),
preference share capital and equity share capital including reserves and surpluses. Leverage or
capital structure ratios are calculated to test the long term financial position of a firm. Generally
capital gearing ratio is mainly calculated to analyse the leverage or capital structure of the firm.
Example of ratios are total debt ratios, the debt/equity ratio, the long-term debt ratio, the times
interest earned ratio, the fixed charge coverage ratio, and the cash coverage ratio.
Asset Efficiency or Turnover Ratios : The asset efficiency or turnover ratios measure the
efficiency with which the firm uses its assets to produce sales. As a result, it focuses on both the
income statement (sales) and the .

Describe the principal costs incurred in the business that employs y.pdf
The principal costs incurred in my current business include fixed costs like rent and utilities, variable costs like materials that fluctuate with production volume, and mixed costs that have both fixed and variable components like payroll. If production volume increased 10%, variable costs per unit would decrease as fixed costs are spread out over more units, while unit fixed costs would remain the same and unit mixed costs would decrease to some extent depending on how much the variable portion increased with production.
Compare and contrast swabs and contact (RODAC) plates for their abil.pdf
Compare and contrast swabs and contact (RODAC) plates for their ability to enumerate bacteria
and viruses from surfaces. (Consider the question carefully, it is a bit of a trick question).
Solution
Swabs and contact (RODAC) plate methods are use for surface sampling for all microorganisms.
In Swabs method, we use sterile cotton or calcium alginate swabs for small surfaces and Sponges
for big surfaces to pick microorganisms and transfer them to broth nutrient medium. This method
is easy to use, Inexpensive and can apply to any surfaces. The main disadvantage of this method
is microorganisms’ recovery is very poor and collectable in broth medium only.
In contact plate or RODAC plate method, the whole plate is pressed against the surface of
chosen and then collect microorganisms. RODAC abbreviates for Replicate Organism Detection
and Counting. This method is usable to smooth surface very efficiently and nutrient medium
flexible. The main disadvantage for this method is, overgrowth occurs if surface is highly
contaminated..
Briefly explain the ventral and dorsal body cavities and the membran.pdf
Briefly explain the ventral and dorsal body cavities and the membranes which line the ventral
cavities. What is a mesentery?
Solution
The ventral body cavity is a body cavity that is in the anterior (front) aspect of the body. It is
made up of the thoracic cavity, and the abdominopelvic cavity. The abdominopelvic cavity is
further divided into the abdominal cavity and pelvic cavity, but there is no physical barrier
between the two. The abdominal cavity contains digestive organs, the pelvic cavity contains the
urinary bladder, internal reproductive organs, and rectum.
The thoracic cavity is separated from the abdominopelvic cavity by the diaphragm. The thoracic
cavity is further separated into the pleural cavity which contains the lungs and the superior
mediastinum which includes the pericardial (heart) cavity.
The organs within the ventral body cavity are called the viscera.
The walls of the ventral body cavity and outer covering of its organs contain a thin covering
called the serosa (also called serous membrane). It is a double-layered membrane made up of two
parts called the “parietal serosa” (lines the cavity walls) and “visceral serosa” (covers organs in
the cavity). The serous membranes are separated by a thin layer of fluid called “serous fluid“.
Serous fluid is secreted by both membranes and acts as a lubricant, allowing organs to slide in
the cavity without causing friction.
The dorsal body cavity is located along the dorsal (posterior) surface of the body, where it is
subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord.
The two cavities are continuous with one another.
The cranial cavity is a large, bean-shaped cavity filling most of the upper skull where the brain is
located.The vertebral cavity is a very narrow, thread-like cavity running from the cranial cavity
down the entire length of the spinal cord. Just as the brain and spinal cord make up a continuous,
uninterrupted structure, the cranial and spinal cavities that house them are also continuous. The
brain and spinal cord are protected by the bones of the skull and vertebral column and by
cerebrospinal fluid, a colorless fluid produced by the brain, which cushions the brain and spinal
cord within the posterior (dorsal) cavity.
The covering and protective membranes for the dorsal body cavity are called meninges..

7. The ability to roll the tongue inward in humans is determined by the dominant gene T. From a
couple both able to roll the tongue, a child is born. The child is unable to roll the tongue. What is
the genotype of each of the parents?
Solution
6.ans-The father cannot be WW
As one allele comes from father as Sally is Ww.
7 ans- the genotype of each of the parents is Tt
On solving by Punitt square the offsprings are TT,Tt,Tt& recessive tt. The recessive tt genotype
offspring cannot roll tongue.
28. What is the proposed role of thioredoxin in seed protein mobiliz.pdf
28. What is the proposed role of thioredoxin in seed protein mobilization?
29. How do monocots and eudicots differ in the placement and activation of the peptidases
needed to mobilize seed storage proteins?
Solution
28)The role of thioredoxin in seed protein mobilization is that it leads to the reduction of
disulfide bonds and they respond of active oxygen species and help in the proteing mobilization.
29)The monocots and eudicots are different. When we have a monocot seed and we open it then
the stored food of the seed is present as one unit .On the other hand the Eudicots have the food
source which is broken into two parts – which is referred by “di”. Moreover when the seed
germinates, the monocot usually forms one seed leaf which is known as the the cotyledon while
the the Eudicot forms two seed leaves
Another difference is that the monocots are represented by the leaves which have parallel veins.
This shows that the veins usually begin at the base of the leaf and these veins usually move
parallel to one another towards the end While the Eudicots have leaves with net veins,.

Write a 250-300 word abstract explaining that the internet is the gr.pdf
Write a 250-300 word abstract explaining that the internet is the greatest acheivement in the 21st
century. It was not invented in the 21st cenury but it has mainly become significant in the 21st
century. USE IEEE format. Thank you!
Solution
The Internet is, obviously, one of mankind’s greatest accomplishments in this Information Age.
But this new technology not only saves time—it wastes it too. It makes life simpler, yet more
complicated; it brings us together, yet pushes us apart.
Now that is a paradox!
Internet is one of the great advances not only of our current culture, but of any culture at any
point in history. The Internet allows for better documentation of the world around us, and we are
slowly getting closer to a completely accurate documentation of history. Heffernan compares
prior historical documentation to the crackle of vinyl records: they are a representation of reality
created by humans but with a low fidelity to reality itself.
Technology, including the internet, is slowly evolving to be better at documenting what life is
like. There are 4D movies, iPhones that can create holograms, and apps to document police
encounters (such as Hands Up) or put dog ears on a selfie (Snapchat.)
As Mark Fischbach, online Youtube personality known as Markiplier, said back in December,
2014: “The global, shining goal of the Internet is to combine everybody and to let everyone talk
with everyone, and unite, and make cool stuff together. I didn’t know it would happen this
quickly.” He’s quite right. The Internet works best when everyone can contribute, and it lets
people across the world interact and learn about other cultures, and other ways of thinking.
Just a few decades ago, sound in movies was a brand new thing, and color wasn\'t even thought
of. It was not that long ago that historians filmed real life Civil War veterans doing the now
famous rebel yell. As Heffernan points out, the Internet and similar technologies are just illusions
of pure documentation, like video of Civil War vets. What\'s more, the Internet is just getting
better...
Our troubles and calamities have not just doubled; they’ve multiplied—thanks to modern
technology! But our God has allowed modern communication methods to dramatically increase.
The Internet is bridging the gap that He put in place some 4,000 years ago.
Already, the minds of the people of the nations of the world have been drawn closer
together—and now, with the help of the digital information superhighway, man has turned earth
into a “global village.” With this invention he’s not only collapsed distance; he’s demolished all
inhibiting boundaries..
Write a program in java in which you will build the“Sink theShipsGam.pdf
Write a program in java in which you will build the“Sink theShipsGame”. The Game has a8 x 8
grid and threeships. Each ship takes up exactly three cells. In the game, it’s you against
thecomputer, but unlike the real battleship game, you don’t place any ships on yourown. Instead,
your job is to sink the computer’s ship in the fewest number of guess.
Goal:Sink all the computer’s ships(three in this case)in the fewest number ofguesses. You’re
given a rating or level, based on how well you perform.Setup:When the game program is
launched, the computerplaces three ships on a8x 8 grid(for an example, see the figure
below).The ships can be placed eithervertically or horizontally (no other placement is valid)on
empty cells of the grid.When that’scomplete the game asks for your first guess.
The computer will prompt you to enter a guess(a cell), that you will type at the command-line as
“1 3”(where “1 3” means 3rdcell ofthe 1strow), “45”, etc.. In response to your guess, you will
see a result at thecommand line,either “Hit”, “Miss”, “Kill” (or whatever the lucky battleship of
the dayis!). When you have sank all three battleships, the game ends by printing out your rating.
Here is a sample run of the game:
Your goal is to sink three ships.
Battleship1, Battleship2, Battleship3
Try to sink them all in the fewest number of guesses

Why is it recommended that vegans take an oral vitamin B12 supplemen.pdf
Why is it recommended that vegans take an oral vitamin B12 supplement? Provide a detailed
answer and back up with research.
Solution
Vitamin B12 or cyanocobalamin- it is a water soluble vitamin so it does not stay in the body for
long time, thus required from dietary intake or supplements.
Sources- liver, fish, shellfish, crabs, tofu, soy milk, egg, dairy products, red meat, cheese etc.
Importance of vitamin B12-
It is observed in various studies that Vegetarians or vegans whose dietary intake does not contain
vitamin B12- rich food items are usually deficient in vitaminB12 and hence are prone to diseases
like-
Depression
Constipation
Confusion and dementia
Cardiovascular diseases
Neurological and mood disorders
Bone disorders
According to a study published online by Kaam S Woo, et al,i n the journal Nutrients, vegans
especially Indians and Chinese are more likely to suffer from metabolic vitamin B12 deficiency.
Also strict vegetarians ( those who totally avoid consumption of eggs and dairy products) are
even more vulnerable to vitamin B 12 deficiency, which eventually affects or alters the arterial
endothelial function and carotid-intima-media thickness (changes in these 2 parameters leads to
atherosclerosis). Further, the deficiency can also lead to neurological disorders like dementia etc.
Thus it is recommended to vegans to consume food fortified with vitamin B12, diary products
and vitB12 supplements. Regular checkup for serum level of vital B12 is mandatory to avoid any
risks that are associated with its deficiency..

True False1. The primary difference, in terms of processing, bet.pdf
- 1. True / False 1. The primary difference, in terms of processing, between gray iron and ductile iron is that ductile iron has a very small addition of Mg or Ce added to generate nodules of graphite in the microstructure. 2. Ferrous based materials are sometimes limited in their use in a given application due to issues such as poor corrosion resistance, high density, and relatively poor conductivity. 3. Annealing is the exposure of a material to an elevated temperature for a short time period followed by quenching to room temperature at a fast rate. 4. Die casting is generally more capital intensive than sand casting and so is better suited for making high volumes of the same part. 5. Over-aging during precipitation hardening processing will result in a decrease in strength of the material. Solution 1.true(Nodule formation is achieved by adding nodulizing elements, most commonly magnesium and, less often now, cerium) 2.false( ferrous based materials have relatively high conductivity) 3.true(for copper, silver and brass can be quenched quickly at fast rate, where as for ferrous metals like steel slow cooling is required to anneal) 4.true( die casting needs more capital investment for casting equipments and metal dies) 5.false( over-aging during precipitation hardening process is done to increase the strength of the material)
