"News that a colleague's baby has taken some first tentative steps usually merits little more than
polite congratulations or an obligatory glance at some e-mailed images. When Nadrian ("Ned")
C. Seeman and William B. Sherman of New York University recently made such an
announcement, however, it earned coverage in several scientific journals. The attention had to
do with the new walker's size, which is very small for its age-or any age. A pair of legs and feet
constructed from DNA strands, the walker stands just 10 nanometers tall-or roughly 1/25,000
the diameter of the period that concludes this sentence. Seeman says the walker's stroll along a
DNA sidewalk is "a natural outgrowth of work that's been done before. Seeman and Sherman,
who christened their pride and joy A Precisely Controlled DNA Biped Walking Device, make
clear that the walker has no practical application. And even, though he calls it "the robot,
Seeman seems wary of characterizing it as a harbinger of submicroscopic automation. He does,
however, see the possibility of some practical uses. "We're going to look at longer sidewalks," he
says. "Eventually we might have it try to carry a load. We'll probably also look into using it for
polymer deformation-maybe using circular sidewalks and have them holding strands and
twisting or braiding them." Bragging rights and applications aside, Seeman sees the walker as
one more event in an accelerating series that is transforming nanotechnology from science
f
iction to science fact-developments that are making nanotechnology a very exciting field to be
in right now. "I figured out this was going to be fun in 1980," Seeman says. "Now that I've been
working in this area for nearly a quarter of a century, it's really starting to snowball." " how many words in this peragraph

On the way to the cove where Nimble Dick led the fool and his two companions, Pod catches Dick looking through Brienne's saddlebags. She knew something like this might happen, and warned Pod to keep an eye on him. But having no recourse but to follow Dick, Brienne and Pod continue on their path to Crackclaw Point.
Dick tells them some of the history of the region, to pass the monotony of their journey. Brienne's mistrust of Dick has made him take notice, and she considers how easy it is for her to suspect others, after the mistreatments she has suffered in her life. She remembers getting her revenge on several of her false suitors during the mêlée at Bitterbridge, but this has done little to stay her natural distrust.
As they pass the Dyre Den, Lord Brune's castle, Pod takes note of a rider a couple miles behind them. When Brienne learns that Dick may have known Lord Brune, she considers the possibility that Dick is a deserter from the war.
After passing through many a treacherous bog and forest, they finally arrive at the ruins of the Whispers. Brienne commands Pod to watch their horses, as she and Dick investigate the ruins. When they find a recently put-out cookfire, Brienne realizes their quarry is still around.
The trap is soon sprung, and the fool turns out to be Shagwell of the Bloody Mummers. Shagwell kills Nimble Dick with his brutal morningstar, then informs Brienne that Urswyck rode south to Oldtown with some of the Mummers, while Rorge headed for Saltpans. He also reveals a rumor that the "daughter of Lord Stark" has last been seen with Sandor Clegane.
When Shagwell's two companions attack, Brienne's strength and size are too much for Pyg and Timeon, who fall quickly to her strokes with Oathkeeper. Squaring off against Shagwell, the Fool is struck in the head by a stone thrown by Podrick.
Brienne forces the Fool to dig a grave for Dick, but upon completion of it, the former Brave Companion attacks her. She quickly dispatches him as well. After killing him, she leaves two gold dragons on Dick's grave, and is then surprised to hear a laugh from the ruined wall.
It is Ser Hyle Hunt, the rider who Pod had spied, sent by Randyll Tarly to stay at Brienne's side in the off chance that she finds Sansa.
Aeron is wading in the ocean, berating himself for running from Euron. He considers Nagga's bones, where the Grey King ruled for a thousand years and warred against the Storm God.
At dawn, Aeron has his drowned men sound the drums and warhorns to announce the onset of the kingsmoot on Old Wyk. The prophet wishes for Victarion to win the claim, and hopes Euron will make a mistake and declare early.
The first claimant is Gylbert Farwynd, who rules a small barrier island far to the west of the Iron Islands where skinchangers are said to live. Aeron sees madness in the lord's eyes. He offers to lead the ironmen to a bountiful land beyond the Sunset Sea; few of the gathered captains shout his name.
Next up is Erik Ironmaker, who once might have made a great king. But age and his immense weight make him an easy target for Asha to dismiss by asking him to stand up from his chair.
The following claimant is another famous ironborn, Lord Dunstan Drumm, who asks the gathering, "Where is it written that our king must be a kraken?" But the Drumm's downfall is the cheap loot he offers to swing the vote of the captains.
Victarion steps forth next and asks for Aeron's blessing. His speech is short and concise and he offers to continue the rule his brother Balon set. His offerings are generous, and many captains give him their voice.
But it is Asha who interrupts the shouts of "Victarion!", and declares that her claim is best as she is Balon's daughter. She tells the ironborn that war is bleeding their people and to continue it would be folly.
She offers peace with the northmen, and prosperous land on the western shores of the North. When she opens her chests to show the scant spoils of her warring in the north, the tumult of support she receives is staggering.
Fearing that a woman will win the kingsmoot, Aeron is shocked back to reality by the horrible bellowing of a horn. All eyes turn to a giant war-horn bound with ancient Valyrian glyphs being sounded by one of Euron's "mongrels".
After sounding the horn several times, the giant mute nearly falls over, his lips bloody and blistering. Euron steps forward and announces that he has sailed further and braved more than any other ironman. He offers not only peace and land, but all of Westeros to the ironborn.
When Asha asks him how he means to do so, her uncle responds that he will use dragons to conquer the Seven Kingdoms, as Aegon the Conuqeror did, using the dragon horn he found amongst the ashes of Old Valyria. When he tells the crowd that the horn can bind dragons to his will, and that he knows where three dragons can be found, he receives the overwhelming cheers of "Euron! Euron! Crow's Eye! EURON KING!"
Victarion has left the defense of Moat Cailin to Ralf Kenning, and sailed the Iron Fleet to Old Wyk for the kingsmoot. When the fleet arrives at Nagga's Cradle, Victarion has them blockade Euron's Silence. The first to greet him on shore is Aeron, and later that night the priest is at his side for the feast. Several captains pledge their voice to Victarion's claim, but Baelor Blacktyde seeks a king who will end the wars, saying,
"Balon was mad, Aeron is madder, and Euron is maddest of them all."
Soon, the captain finds his niece, advising her not to lay forth a claim, because a woman has no place ruling the ironborn. Asha stands by her claim, and notes that the Damphair may have underestimated the appeal of the kingsmoot, since the Drumm will present his claim and there is talk of Maron Volmark being presented as heir of the throne by Tarle the Thrice-Drowned, while it is apparent that Aeron's intent was to legitimize Victarion as Balon's successor.
Their chat is interrupted by the arrival of Euron. Victarion notes Euron does not seem to have aged in the almost three years that he has been gone. Aeron confronts Euron with the accusation that "no godless man may sit the Seastone Chair", but Euron cows his brother into leaving the hall.
Asha then accuses her uncle of the death of her father, but Euron denies he had anything to do with it. When a fight nearly breaks out between Asha and one of Euron's men, Victarion steps in and demands that Euron leave.
After his departure, Victarion and his niece walk outside, and Asha asks why Euron was banished by her father, for he refused to ever speak of it. Victarion eventually tells her that Euron impregnated Victarion's wife. Victarion wanted to kill his brother but Balon forbid it and sent Euron to exile. Later Victarion killed his wife with his own hands.
Asha offers to set aside her claim if Victarion will name her his Hand of the King and end the war. She feels that the Ironborn have overextended themselves and tells her uncle that she has reached an agreement with Lady Sybelle Glover, and that their people may keep Sea Dragon Point and the Stony Shore in return for the release of Deepwood Motte, Torrhen's Square, and Moat Cailin. Victarion is not receptive. Asha replies that she then will claim the throne.
EXERCISE – RISKS
i) Risk Register
Risk management should be seen as a vital role of any Board under any organisational structure. It shows a commitment to minimising risks and maintaining a sound set of internal controls so that the business remains a going concern. From a governance perspective, a risk register is essential.
It allows the Board to see any new risks and identify changes to existing risks. Companies can use it to prioritise risks by looking at the likelihood of the risk occurring and the impact it may have.
Often a risk register will turn this into a numeric value to rank risks and highlight the key ones.
Then an appropriate risk management strategy can be determined to mitigate the risk. It can also ensure that the best is made of any opportunities that arise.
Controls can reduce risks, but are not the only way to deal with risks. Diversification, hedging and or joint ventures could be used to help reduce risks. Risks can also be mitigated through risk transfer such as insurance and/or outsourcing. Certain risks are considered to be so severe the activity may be avoided.
A detailed risk register for Rotomyne should have the following elements:
• Risk Description: A comprehensive explanation of each risk. For instance, Rotomyne might detail risks associated with "Environmental Impact" by referencing specific types of environmental damage such as soil erosion, water pollution, and habitat destruction due to mining operations.
• Ratings for Likelihood and Impact: Assigning a probability of occurrence and a measure of potential consequences to each risk. For example, given Rotomyne’s international presence, "Geopolitical Instability" in certain markets could be rated as medium likelihood but high impact, due to potential disruptions in mining operations or risks to employee safety.
• Overall Risk Rating: A composite score that synthesizes likelihood and impact assessments. This might involve scoring each risk on a scale from 1 to 5, with 5 being the most severe, and then multiplying the scores to arrive at an overall risk rating. For instance, a risk with a high likelihood (4) and high impact (5) would have an overall rating of 20.
• Identification Date: The date when the risk was initially recognised, which could be particularly relevant for emerging risks such as "Cybersecurity Threats" due to the integration of OT and IT systems.
• Last Review/Change Date: This would reflect the most recent assessment or modification of the risk, which is essential for dynamically evolving risks such as "Technological Obsolescence" where Rotomyne needs to continuously innovate in lithium extraction and processing techniques.
• Residual Risk Rating: The degree of risk that persists after mitigation strategies have been applied. For instance, even with advanced safety protocols, the "Risk of Industrial Accidents" might still carry a residual risk due to the inherent dangers of mining operations.
• Risk Owner: An individual appointed to oversee the management of each risk. In Rotomyne’s case, the "Production Director" Dr Andrey Prokhorov might be the risk owner for "Environmental Impact" due to the close connection with mining and processing activities. The risk owner would be responsible for implementing and reviewing the effectiveness of environmental protection measures.
ii) Additional Risks and Mitigations
In terms of additional risks and mitigations for these risks, below are some other factors that could pose issues for Rotomyne and how they could be mitigated: (This is not an exhaustive list & you may think of more risks and different mitigations)
Corporate Reputation Risk The danger that negative perceptions could damage Rotomyne's brand and financial standing. In the mining sector, where environmental and social responsibility are paramount, Rotomyne’s clients and stakeholders depend on the company to operate sustainably and ethically. Any lapse in environmental practices, employee misconduct, data breaches, or adverse media attention can severely impact Rotomyne’s reputation.
• Mitigation: Rotomyne has implemented several risk management strategies to maintain its reputation and ensure the safety and quality of its operations. It conducts rigorous environmental assessments and adheres to strict regulations. The company also invests in community engagement and corporate social responsibility initiatives. Additionally, Rotomyne could benefit from media monitoring and a formal crisis management plan to proactively manage and safeguard its reputation.
Operational Risks These could include supply chain disruptions, where delays or issues with suppliers of mining equipment or technology could hinder production. Additionally, Rotomyne might encounter challenges related to the integration and compatibility of various mining and processing systems, especially when operating in diverse geographical locations.
• Mitigation: To mitigate supply chain risks, Rotomyne could develop a diversified supplier network to avoid reliance on a single source and create contingency plans for critical supplies. Regular audits and evaluations of suppliers’ capabilities and financial stability can also help to anticipate and manage potential supply chain issues. For the integration of mining systems, Rotomyne could invest in cross-platform technologies and employ specialists to ensure seamless integration of different mining infrastructures.
Product Reputation Risk Rotomyne’s reputation hinges on the reliability and effectiveness of its lithium products. Product failures, inaccurate geological surveys, or subpar processing could tarnish the company's standing as a trusted lithium supplier.
• Mitigation: Rotomyne should implement stringent quality controls, invest in ongoing staff development, actively seek customer feedback, and communicate product capabilities transparently. Regularly updating processing technology and maintaining high standards in product quality can also help in mitigating these risks.
Technology and Cybersecurity Risks With the increasing integration of Operational Technology (OT) and IT systems, Rotomyne faces significant cybersecurity risks that could disrupt operations or compromise sensitive data.
• Mitigation: Rotomyne should implement robust cybersecurity measures, including data encryption, network security protocols, and regular security audits. Training employees on cybersecurity best practices and developing a comprehensive incident response plan can also help mitigate these risks.
Environmental Regulatory Compliance Risk Rotomyne operates in multiple countries, each with its own set of environmental regulations. Non-compliance can result in significant fines, legal action, and damage to the company’s reputation.
• Mitigation: Rotomyne should ensure full compliance with all relevant environmental regulations across its operations. This includes implementing a centralised compliance monitoring system and conducting regular audits. The company should also exceed local regulations by adopting the strictest global standards. Continuous training for staff on environmental laws and best practices can further mitigate this risk.
Economic and Market Risk The prices of lithium compounds are highly volatile and are influenced by global supply and demand dynamics. Economic downturns can also reduce demand for lithium products, impacting Rotomyne’s revenues and profitability.
• Mitigation: Rotomyne can use hedging strategies to manage price volatility. Diversifying its product range and customer base can also reduce dependency on specific markets. Additionally, maintaining strong relationships with key customers and continuously monitoring market trends can help the company to respond quickly to economic changes.
Geopolitical Risk Rotomyne has mines in countries with varying degrees of political stability. Geopolitical events such as changes in government, civil unrest, or trade restrictions can disrupt operations.
• Mitigation: Rotomyne should develop contingency plans for each of its mining locations, including alternative supply chains and evacuation plans for employees. Building strong relationships with local governments and communities can also help to mitigate this risk. Diversifying mining operations across multiple stable regions can further reduce the impact of geopolitical events.
Supply Chain and Logistics Risk Rotomyne’s operations depend on a complex supply chain for equipment, materials, and logistics. Disruptions in the supply chain can impact production and delivery schedules.
• Mitigation: Developing a diversified supplier network and maintaining strong relationships with key suppliers can help mitigate this risk. Implementing robust supply chain management systems and developing contingency plans for critical supplies can also enhance resilience. Regularly reviewing and optimising logistics processes can further mitigate supply chain risks.
Human Resource Risk Attracting and retaining skilled professionals, particularly in remote mining locations, can be challenging. High turnover rates can disrupt operations and increase recruitment and training costs.
• Mitigation: Rotomyne should invest in employee development and offer competitive compensation packages to attract and retain talent. Providing a safe and supportive work environment, along with opportunities for career growth, can also help to reduce turnover. Developing strong employer branding and engaging in community outreach can further enhance the company’s ability to attract skilled professionals.
Health and Safety Risk Mining operations pose significant health and safety risks to employees. Accidents or unsafe working conditions can lead to injuries, legal action, and reputational damage.
• Mitigation: Rotomyne should implement stringent health and safety protocols and ensure compliance with all relevant regulations. Regular safety audits, training programmes, and the use of advanced safety equipment can help to mitigate this risk. Promoting a strong safety culture and involving employees in safety initiatives can further enhance workplace safety.
Ethical Risks Rotomyne must navigate various ethical dilemmas, such as labour practices, community impact, and environmental sustainability. Ethical lapses can lead to legal action, reputational damage, and loss of stakeholder trust.
• Mitigation: Rotomyne should establish a robust ethical framework, including clear policies and codes of conduct. Regular training on ethical practices for employees and management can help foster an ethical culture. Implementing a whistleblower policy and ensuring transparency in operations can also mitigate ethical risks. Engaging with stakeholders and maintaining open communication channels can further enhance ethical compliance.
Environmental Sustainability Risks The extraction and processing of lithium have significant environmental impacts, including habitat destruction, water pollution, and carbon emissions. Failing to manage these impacts can lead to regulatory penalties and reputational damage.
• Mitigation: Rotomyne should adopt sustainable mining practices and invest in technologies that reduce environmental impact. This includes using direct lithium extraction methods where feasible, which have lower environmental footprints. Regular environmental impact assessments and compliance with the highest environmental standards can also help. Engaging in reforestation and habitat restoration projects, as well as reducing carbon emissions through renewable energy sources, can further enhance environmental sustainability.
Hydraulic, electric, and hydro-electric power steering systems represent the most common types you're likely to find on modern vehicles. However, those systems can rely on different mechanisms and parts to transfer your steering wheel's motion to the wheels. We've covered rack and pinion steering already, but now we'll briefly discuss some of the other gear systems you're likely to see. Outside of rack and pinion gears, worm gears are one of the most common types of steering gears you'll encounter. These devices encompass various kinds of steering systems, including the traditional Pitman arm setups found in older cars and trucks, as well as some modern off-road vehicles like certain Jeep models. Besides worm gear systems, other relatively common types of power steering systems include recirculating ball and RAM-type steering systems. While recirculating ball systems are usually found on off-road and heavy-duty vehicles, RAM-type systems are more commonly used in marine applications.
Rack and pinion steering systems — as they're sometimes called — are an extremely common type of power steering system. You can find them in both standard hydraulic and newer electric power steering systems, and unless you drive an antique car or a modern off-road vehicle like a Jeep, chances are that your vehicle has a rack and pinion gear. These components are designed to transform the rotational motion of your steering wheel into the linear movement necessary to aim the wheels of the car. Rack and pinion systems work using an ingenious and highly complicated set of gears. They're essential parts of your car's steering and suspension systems, and they play key roles in keeping your wheels aligned and your tires in good condition. If you're interested in learning more about rack and pinion steering, stick around. As a former professional mechanic who spent years specializing in steering and suspension, I'll break it down for you. We'll explore how these parts work, and we'll compare them to some other popular types of steering systems. Let's dive in and check it out.
If you've ever driven an older vehicle without power steering or a contemporary car with a power steering malfunction, you probably understand just how important these systems are. They drastically reduce the amount of force necessary to turn the steering wheel, making it substantially easier to maneuver your car. However, not all power steering systems are created equal or work using the same methods and power sources. Today, the two most common types of power steering systems are hydraulic power steering systems and electric power steering systems. But while these systems rely on different sources of power, they often function using similar gears and components, including the famous rack and pinion gear.
