This document discusses the history and development of coronary stents. It notes that the introduction of angioplasty led to the development of stents to address the problem of restenosis. Early stents were bare metal, but drug-eluting stents were developed to further reduce restenosis rates by preventing neointimal growth. The document covers the various types of stents developed over time including differences in materials, coatings, and platforms. It also discusses the rationale for biodegradable stents which aim to eliminate complications from permanent metal implants.
This document discusses guide catheter extensions used in interventional cardiology. It describes four types of guide catheter extensions currently available: Guideliner V2, Guidezilla, Telescope, and Guidion. It provides details on the sizes, lengths, and features of Guideliner V2 and Guidezilla. Applications of guide catheter extensions include increasing backup support, bypassing calcification/tortuosity, limiting contrast use, and facilitating procedures like CTO PCI and thrombus aspiration. Potential complications are discussed, along with tips to minimize risks like dissection or ischemia.
Social media provides fast communication and opportunities for sharing and business but it can negatively impact social life. While social media connects people globally and builds personality, it can hack social life by reducing family gatherings and physical activity. The top three social media sites - Facebook, YouTube, and Twitter - generated billions in annual revenue in 2016 but social media risks privacy and health.
This document discusses various adjunct devices that are used in percutaneous coronary interventions (PCI). It describes plaque modification devices like cutting balloons and lasers that can facilitate procedural success and reduce restenosis. Cutting balloons make controlled incisions in plaque to enlarge vessels at lower pressures. Lasers precisely remove plaque but are infrequently used due to high cost. Thrombectomy devices like manual aspiration catheters can reduce thrombus burden in acute myocardial infarction to improve perfusion. Embolic protection devices trap debris during stenting of saphenous vein grafts to prevent distal embolization.
This document discusses coronary guidewires used in percutaneous coronary intervention (PCI). It begins by outlining the history of angioplasty and guidewire development. It then covers the purpose, components, classifications, and appropriate uses of guidewires. The main components include the core, tip, coils, covers, and coatings. Guidewires are classified based on flexibility, device support, and clinical usage. Complications like vessel perforation, pseudolesions, and entrapment are also discussed. Proper guidewire manipulation and strategies for difficult lesions are outlined to maximize safety and efficacy.

Bioabsorbable stents are manufactured from materials that dissolve in the body over time. They serve the same purpose as traditional metal stents by expanding a blocked blood vessel, but eventually degrade so the vessel is freed from the scaffold. Polymer-based materials like PLLA and absorbable metals such as magnesium alloys are being tested. Bioabsorbable stents could overcome limitations of permanent metal stents by eliminating risk of late thrombosis and local inflammation once dissolved. Several types are currently in clinical trials and projected to gain significant market share as they receive FDA approval.
This document discusses optical coherence tomography (OCT) in coronary artery disease. It provides an overview of OCT, including its history and clinical evidence.

Are Social Media Websites Harmful To The Youth?Evan Atkinson
This study was done to determine if social media websites negatively affect the youth of America. Many young people in the United States have accounts on social media websites such as Facebook, Twitter, and MySpace and studies have shown that these websites can have negative affects. With so many young people using these social media sites, studies on the negative affects should surely be done. After conducting a survey, and analyzing many secondary academic resources I determined that in fact the youth could be negatively affected by these social media websites. They are negatively affected in many different ways such as them being addictive, and distracting in an academic environment, but also can affect the youth negatively in several other ways. After coming to these conclusions, I am certain that more studies need to be done on this issue, so we can reverse some of the negative aspects of social media websites, and find a way to be able to use them in the best possible way.
The document provides background on India's growing energy needs and its plans to increase nuclear power capacity. It discusses the Koodankulam nuclear power plant project in Tamil Nadu, which initially faced little opposition but grew as residents realized it did not provide jobs as promised and could threaten their livelihoods from fishing. The 2011 Fukushima disaster intensified protests against the project. The government insists on the plant's safety, but protesters demand more transparency and representation. Tensions increased with police action against protests, legal battles, and intimidating shows of state power. Key issues raised include whether lower classes should risk their lives and livelihoods to fuel energy growth mainly benefiting other classes.

A woman’s lack of education also has a negative impact on the health and wellbeing of her children. For instance, a recent survey in India found that infant mortality was inversely related to mother’s educational level
The document discusses women's empowerment in India. It defines women's empowerment as accepting women into the decision making process and raising their status through education, awareness, and training. Women's empowerment is important for a country's development by enhancing human resources. In India, women's empowerment depends on location, education, socioeconomic status, and age, though policies exist, implementation lags. Education is key to empowerment by enabling women to confront traditional roles. The status of women has improved in modern India through cultural and structural changes, and women now participate in all fields, though disparities remain between policy and reality.

The financial theory of investment proposes that a firm's cost of capital, and thus its investment decisions, depends on the source of funds. A firm has three sources of funds: retained earnings, which are the cheapest; borrowed funds, whose cost rises with the amount borrowed; and new equity, which is most expensive. The marginal cost of funds curve depicts how a firm's cost of capital rises as it uses more funds from each source. In recessions, investment depends on retained earnings as firms cut costs, but in booms, when demand is high, firms borrow more and interest rates influence investment. The theory is criticized for ignoring capacity expansion and long-term investment decisions, as well as the greater effectiveness of fiscal versus monetary
International economics deals with the economic relations among nations. The resulting interdependence is very important to the economic well-being of most nations of the world and is on the increase. The economic relations among nations differ from the economic relations among the various part of a nation. This gives rise to different problems, requiring somewhat different tools of analysis, and justifies International Economics as a distinct and separate branch of “Applied” Economics.
International economics deals with
1) The Pure Theory of Trade. This examines the basis for trade and the gains from trade.
2) The Theory of Commercial Policy. This studies the reasons for and the results of obstructions to the free flow of trade.
3) The Balance of Payments. This examines a nation’s total payments to and total receipts from the rest of the world. These involve the exchange of one currency with others.
4) Adjustment in the Balance of Payments. This deals with the mechanism of adjustment to balance of payments disequilibria under different international monetary systems.
The Major reason for the people’s demand for money is that it is needed in any economy in which almost every person and firm sells goods and services for money and in turn uses money to buy the goods and services offered by others. Functionally this amount of money used as a medium of exchange. Classical theory explained the demand for money as essentially a demand resulting from this need for money as medium of exchange.
In Keynesian theory, money becomes much more than a medium of exchange, much more than a medium of exchange, much more than a device for meeting transactions in the marketplace. People also demand money for speculative purposes and as security against unforeseen needs for cash reserves. The break down of the demand for money into transactions and precautionary and speculative demands plays a vital part in the theory of Keynes.
The trade cycle refers to the ups and downs in the level of economic activity which extends over a period of several years. If we examine the past statistical record of the business conditions, we will find that business has never run smoothly forever. There are many fluctuations in the period. Sometimes prosperity is followed by adversely. In Economics this tendency of the business activities, to fluctuate from prosperity to adversely is called business cycle.
Prof. Keynes says: " A trade cycle is composed of periods of bad trade characterized by falling prices and high unemployment percentages while a period of a good trade is characterized by rising prices and high employment, percentages."
Paul H. Douglas, Professor at the University of Chicago introduced the production function in 1934. Another prominent economist Robert Solow has also conducted extensive research and found out how the technological progress has improved the productivity of inputs, viz., capital and labour in America.
In modern terminology, the various factors like land, labour, capital, organization skill, raw materials and other factors made use of in production are given a wider connotation called inputs. The product realized due to the inputs is called output. Inputs indicate the cost involved in procuring various factors, commodities as raw materials, power, etc., while output indicates the goods and services produced. Production is a process in which the physical inputs are transformed into physical output. The output is thus the function of inputs. The functional relationship between physical inputs and physical outputs of a firm is known as a production function. The production function is a catalogue of output possibilities.
Among several laws of production, the law of Diminishing Returns is the oldest and universal law. This law establishes a relationship between input and output and points out that with increasing input, output has a tendency to decline under certain circumstances. The classical economists associated the law of Diminishing Returns with agriculture as they thought that this law manifested in agriculture as they thought that this law manifested in agriculture (land).
Economists agree that supply means the commodity offered for sale at a price. In other words, supply refers to total supply offered for sale at a price to retailers and wholesalers. Sometimes the term market supply is used to denote the supply of perishable commodities with retailers only.
Break-even analysis is a study of costs, revenues and sales of a firm and find out the volume of sales where the firm’s costs and revenues will be equal. The Break-even point is the zone of no-profit and no-loss as the costs equal revenues.
This document discusses and compares commercial banks and development banks. It provides details about the key differences between them.
Commercial banks focus on lending and borrowing activities to earn profits. Their main aim is to earn interest. Development banks, on the other hand, provide loans at lower rates of interest for promoting specific sectors of the economy like agriculture, small industries, etc. Their main aim is socio-economic development rather than profits.
Some major development banks mentioned are regional rural banks, small industries development banks, nationalized banks and their role in promoting priority sectors.
Confirmation of Payee (CoP) is a vital security measure adopted by financial institutions and payment service providers. Its core purpose is to confirm that the recipient’s name matches the information provided by the sender during a banking transaction, ensuring that funds are transferred to the correct payment account.
Confirmation of Payee was built to tackle the increasing numbers of APP Fraud and in the landscape of UK banking, the spectre of APP fraud looms large. In 2022, over £1.2 billion was stolen by fraudsters through authorised and unauthorised fraud, equivalent to more than £2,300 every minute. This statistic emphasises the urgent need for robust security measures like CoP. While over £1.2 billion was stolen through fraud in 2022, there was an eight per cent reduction compared to 2021 which highlights the positive outcomes obtained from the implementation of Confirmation of Payee. The number of fraud cases across the UK also decreased by four per cent to nearly three million cases during the same period; latest statistics from UK Finance.
In essence, Confirmation of Payee plays a pivotal role in digital banking, guaranteeing the flawless execution of banking transactions. It stands as a guardian against fraud and misallocation, demonstrating the commitment of financial institutions to safeguard their clients’ assets. The next time you engage in a banking transaction, remember the invaluable role of CoP in ensuring the security of your financial interests.

Each cryptocurrency transaction is recorded on a public ledger, ensuring transparency and security.
Cryptocurrencies can be used for various purposes, including online purchases, investment opportunities, and as a means of transferring value globally without the need for intermediaries like banks.
Fabular Frames and the Four Ratio ProblemMajid Iqbal
Digital, interactive art showing the struggle of a society in providing for its present population while also saving planetary resources for future generations. Spread across several frames, the art is actually the rendering of real and speculative data. The stereographic projections change shape in response to prompts and provocations. Visitors interact with the model through speculative statements about how to increase savings across communities, regions, ecosystems and environments. Their fabulations combined with random noise, i.e. factors beyond control, have a dramatic effect on the societal transition. Things get better. Things get worse. The aim is to give visitors a new grasp and feel of the ongoing struggles in democracies around the world.
Stunning art in the small multiples format brings out the spatiotemporal nature of societal transitions, against backdrop issues such as energy, housing, waste, farmland and forest. In each frame we see hopeful and frightful interplays between spending and saving. Problems emerge when one of the two parts of the existential anaglyph rapidly shrinks like Arctic ice, as factors cross thresholds. Ecological wealth and intergenerational equity areFour at stake. Not enough spending could mean economic stress, social unrest and political conflict. Not enough saving and there will be climate breakdown and ‘bankruptcy’. So where does speculative design start and the gambling and betting end? Behind each fabular frame is a four ratio problem. Each ratio reflects the level of sacrifice and self-restraint a society is willing to accept, against promises of prosperity and freedom. Some values seem to stabilise a frame while others cause collapse. Get the ratios right and we can have it all. Get them wrong and things get more desperate.

2. INTRODUCTION
Most of the people in the world know the term ‘social media and networking’. Even the people living
in the remote areas of the world have at least heard of Facebook, Twitter, Gmail, Whatsapp,
Instagram, Blog, YouTube and etc. are probably using them on a regular basis. Social network sites
(SNSs) like now popularly use Social media facilitate the development of online social networks by
connecting a user's profile with those of other individuals and/or groups.
In Tamil Nadu the impact of social media is very high among the younger generation. Because of the
social media and networking the youngsters made tremendous contribution during the Chennai flood,
Cyclone Vardah, Jallikattu issue, Protest against Pepsi and Coke and many more issues. During
Jallikkattu issue the social media and networking brought millions of people in to the street and fight
for the cause. Atleast one person in a family participated in the mass people moment created through
social media.
3. JALLIKATTU Issue
If there is one thing to take away from the Jallikattu protests at the Marina beach, Tamil Nadu, it is the power
of social media and the ripples it can create in our daily lives. Four years back Jallikattu got banned, but
at that time, peoples agitation was not succeeded, this time it succeeded only because of social media.
#We do Jallikattu was one of the first hashtags to pop up. The hashtag started getting traction even before
Pongal, becoming a conduit to aggregate supporters.
Several versions of the hashtag like #I Support Jallikattu, #We do Jallikattu, #Amend PCA, #Justice for
Jallikattu started trending ferociously
Initially Only 10 people were gathered and shouted slogan in the morning 10.am. But within a day more than
lack people joined with them. Next day More than one million people joined voluntarily and the same trend
spread all over the state.
End of the 10th day a New legislation was passed in the special assembly session. This is
the power of social media.
6. After Jallikattu protests, Pepsi and Coca-Cola
Banned in Tamilnadu
As far as the public awareness is concerned, there has been a great awareness
gaining moments among the people over the health issues. The recently
conceded Jallikattu issue proved ways for health awareness.
In taking many soft drinks expediently soft drinks made by many MNC, is mater
of great concern. It is believed that there is toxic agents present in these soft
drinks.
It does not know wealth this is correct or not but this news spread out swiftly
among the people only because of using social media.
Within 10 days the Pepsi and Coke lost their 75 percent of their Business
Therefore, it is said that the social media helps to social transformation through
10. Chennai Cyclone and Flood
During the Cyclone the Tamil Nadu youth have actively taken to social media for a cause. The floods in
December 2015 were a clear example and so was Cyclone Vardah. As Cyclone Vardah makes its landfall in
Chennai, social media platform- Facebook, started its “Safety check” option for all those in south India who
may get affected due to this natural disaster.
On the other hand the youth started their actions with the support of social media. The core team begins a
dual operation plan: rescue and rehabilitation. Overnight, a new control centre is created with all operations
under one roof. Volunteers furiously share details. There’s no time to analyse why requests are not coming
down.
As young professionals return to work, new volunteers arrive. Who are these young smart girls with clipped
accent who effortlessly blend with a team of drivers and helpers, carrying boxes with ease and heading into
suburbs? Chennai girls
14. Chennai Cyclone and Flood
The water has still not drained in many parts of the city. More news of electrocution accidents
trickles in. We are too numb to react. Stories and visuals of homes are shared. People
experience the horror of returning to devastated homes.
How can this new section of self-made middle-class individuals, which is not used to taking
charity from anyone, come to terms with this reality? Heartbreaking
Massive rehabilitation was made with the support of social media during this issue. Entire
Chennai people came together with the support of their social media network and contributed
to the needy in time
15. Chennai Cyclone and Flood
From weather forecast updates on skymet, to latest updates on Twitter of how to
commute from one point to another based on which roads the water had receded.
Every time the mobile signal improved everybody tried to reach out to their loved ones
by posting and commenting on Twitter, Facebook, etc., which happened
instantaneously unlike messaging which takes time to send or download, thereby
enabling communication before the signal went off again.
Even as normal calls were not going through, the calls made through WhatsApp were
having lesser drop rates, helping people stay in touch
16. Neutrino & Hydrocarbon Issue
Thanjavur District of Tamil Nadu known for its paddy cultivation, where Govt. of India permitted to
conduct hydrocarbon tests, which will affect the ground water and agricultural lands.
During the same time Govt of India permitted to establish Neutrino testing facility in Tamil Nadu.
The farmers strongly object both the cases and started their agitation.
Neutrinos are abundant subatomic particles that are extremely hard to detect. Billions pass through each square
centimetre of Earth every second, but barely any leave a trace. But if the INO is not built soon, other projects —
including one that broke ground in China a year ago — may get there first, says D. Indumathi, a theorist at the Institute
of Mathematical Sciences in Chennai who is part of the INO collaboration, and coordinates outreach for it. “Longer than
a year of delay and I think it will be difficult to have viable physics goals, at least of the current type,” she says.
Since then, however, local environmental organizations and regional politicians have taken up the issue, and the list of
objections has swelled to include fears that the lab will emit radiation and store nuclear weapons, and that the excavation
will threaten a nearby dam.
Now this project got suspended due to the strong objection and doubts raised through social media
networks. Many villagers have turned against the project without understanding the reality
19. Social Media And Fisherman Issue
The issue of fishermen killing, arrests and fishing vessel seizures between Indian and Sri Lanka has
dragged on for several years. More than 535 fisherman were killed by Srilankan Navy during last 10 years.
In a latest incident, the Sri Lankan Navy allegedly fired at a group of Indian fishermen on Monday who had
allegedly crossed over into Sri Lankan waters on the lookout for fresh catch.
One fisherman was killed in the incident and three others were injured. The Sri Lankans opened fire on the
fishermen who were apparently fishing off the coast of Tamil Nadu between Dhanushkodi and Katchatheevu
Both countries are separated by the International Maritime Boundary Line (IMBL). Often, fishermen from both
sides cross over to the other side for bottom trawling fishing expeditions and that results in arrests and, on many
occasions, shootings
Now the Tamil fishermen, Tamil Nadu’s political fraternity and the Centre are embroiled in a disagreement. Tamil
fishermen believe that Katchatheevu is traditionally their territory and so they have a right to fish there
Because of the recent social media boom this issue became very serious now in Tamil Nadu
21. Social Media And Politics
A democratic society relies upon voter decision to elect representatives and
upon mass media communication networks to inform the electorate.
The Mass media of communication enable the state and its leaders to reach
people even the remote corners of the country.
His constructive political communication can help to solve some of the
problems like economic crisis, political turmoil, social and ethnic unrest
and the age-old injustice and exploitation
