Cybersecurity is concerned with the security of digital data available on the Internet, or on devices connected to the Internet. The risks range from phishing to Trojan horse programs to viruses to collect or erase data and harm the target. Cybersecurity also is concerned with the availability of correct information, as hackers sometimes work to stop some sites by sabotaging their systems with malicious programs. And if I had solace, I would say, it is unfortunately not possible to use the law to prevent all types of piracy, for several reasons, the most important of which is that every day pirates develop a new method to attack the opponent, which makes it impossible to develop mature laws for all kinds of hacks, not to mention that some governments encourage hacking indirectly. FBI once asked a cell phone manufacturer for a way to bypass the security on a phone made by the company, as the FBI wanted access to a criminal's data to see if that person planned a second crime. Accordingly, this company should develop Trojan horse programs to respond to the requests of the FBI; These programs can be misused by employees of the company, without leaving any trace on such use.

In October 2013, Brazilian President Dilma Rousseff announced the abandonment of Microsoft Outlook mail after the revelation of the scandal of spying by a US agency on a Brazilian oil company. A document revealed by the Brazilian media network Globo said that the United States was conducting espionage operations on major companies such as the Brazilian oil giant Petrobras.

In May 2021, British Foreign Secretary Dominic Raab issued a warning to Russia about its hosting of cyber-attacks for ransom. The minister stated that educational institutions were hacked this year for money, which affected their ability to return to teaching face to face.

The US company, Colonial Pipeline, is currently dealing with a ransom operation that shut down a pipeline that supplies nearly half of the US East Coast. The attack is attributed to a cyber gang called Darkside believed to be active in Russia. Former US intelligence officials have said that such groups cannot operate without at least the tacit approval of Russian intelligence, or the country's politicians.

In fact, most of the hacking is done by an internal client, who deals with the hacker. A man named Edward Snowden published files showing that the US government was secretly collecting data on many citizens and foreigners.

In addition, part of the data leaks due to purely social factors. Chatting with a different number of employees of a company, and then by intersect of what each said with others’, enables competitors to infer true and valuable facts about this or that company.

So, we at Canada Engineering have developed several strategies for the data structure inside the company, so that intersection of leaked information is not feasible. This approach is appropriate to address cases like WikiLeaks and Edward Snowden incidents; This strategy is also very suitable for combating hacking-for-ransom operations, as the ransom is shared by hackers abroad and clients inside the company.

As for the issue of malware, infiltrated through phishing operations or Trojan horse programs - large companies may be affiliated with other hacking programs - we have developed in Canada Engineering a unique method, which relies on misleading the pirates at a time, and at other times muck them in the mud

The concept of smart cities aims to provide the highest life and well-being standards for city residents while preserving their health, mental and psychological integrity, while providing a mature vision for the healthy growth of cities, while making maximum use of all resources. To achieve the concept of smart cities, an infrastructure supported by IoT must be fully available, in addition to the availability of a central electronic administrative body for the city supported by a computer control system that organizes the work of the infrastructure, and provides all the required services such as:

1.     A smart navigation system for traffic management, supported by a smart street lighting system that supports traffic and saves energy.

2.    A smart system for managing security activities.

3.    A smart system for managing health activities, including a system for detecting and monitoring the spread of diseases and epidemics.

4.    A smart system for managing educational activities.

5.    A smart system for managing economic activities.

6.    A smart system for managing sports activities.

7.    A smart system for managing social activities.

8.    Smart electricity distribution network.

9.    Intelligent water distribution network.

10. A smart sewage networks.

11.  Smart waste management.

12. Intelligent environmental monitoring service to monitor and determine the levels of rain, snow, wind movement and the degree of air and water pollution in and outside the city neighborhoods.

13. Intelligent disaster control system, such as rapid response to fight fires, forest fires, earthquakes, explosions, floods, hurricanes, volcanoes, and so on.

Canada Engineering's philosophy on mature smart cities ascends the level where humans can coexist with robots seamlessly, where robots can perform their activities to the fullest, including the robot's ability to sense a red traffic light and cross the street safely, and shopping for fresh vegetables and fruits, accompanying children to school and bringing them home, doing household cleaning and other household activities such as cleaning the garden, ironing clothes, washing dishes, and other routine activities. This philosophy stems from our keenness in Canada Engineering to develop Canadian regions, provinces, and cities on the moon, where robots will have a pivotal role in building and developing them, at least in the early stages.

The world is struggling to limit global warming, which is now threatening its infrastructure and cities. Developed countries are heading towards using electricity in all aspects of life to reduce carbon dioxide emissions, knowing that all these countries produce more than 55% of their electricity needs from sources that pollute the environment, unless we exclude Canada, where it produces 66% of its needs from electricity is from renewable sources, while 34% of its electricity needs are produced from sources that pollute the environment.

The clean electricity available now has two downsides. The first is that it is not abundant, and the second is that the cost of production is prohibitive, almost twice the cost of producing electricity from fossil sources.

Therefore, in Canada Engineering, we are aware of the size of our responsibility to save the world from a certain environmental disaster. We have developed decisive strategies that will provide a surplus of clean electricity that will make the shift towards the use of electricity in all aspects of life, such as the transportation sector, a solution to the problem of global warming and significantly reducing the emissions carbon dioxide.

      Canada Engineering has developed new engineering models of windmills - wind turbines, which would double the electricity production of current turbines.

      Engineering Canada has also developed models to take advantage of hydraulic energy, to increase hydroelectric production to more than three times its current electricity production.

      In addition to this, Engineering Canada has developed models to take advantage of renewable energy sources that have not yet been exploited.

Providing a surplus of clean electrical energy at a low cost will lead the world to switch to electrical energy in a timely manner. In fact, the world will witness an upsurge in the local and global economies that is directly proportional to the size of the surplus in clean electrical energy production, and inversely proportional to the cost of production and sale.

On September 16, 2020, the federal government presented a $50 billion plan to dramatically increase the use of hydrogen as a low-carbon fuel to help meet its goals of reducing greenhouse gas emissions. "This strategy is a challenge for all of us, and that is to make Canada the world's first low-carbon hydrogen producer," Natural Resources Minister Seamus O'Regan said. The government announced that the plan would create 350,000 jobs.

On March 16, 2021, Germany and Canada agreed to explore joint development of green hydrogen produced using Canadian hydroelectric sources, for export to Germany. “Canada has the advantage of natural resources and the urgent need to reduce emissions,” Oregon's minister said in a webcast, while German Economy Minister Peter Altmaier said both countries had identical ambitions to achieve climate neutrality by 2050. Neither minister gave details of the quantities of hydrogen that would be produced or exported.

Germany has a semi-integrated infrastructure for the use of hydrogen fuel.

The use of hydrogen is one of the possible ways to eliminate carbon dioxide emissions in sectors that cannot be converted into electric energy, such as heavy transport and heavy machinery, and mainly the heavy industrial sector.

Hydrogen is produced cleanly without carbon dioxide emissions from water by separating hydrogen molecules from oxygen using electricity, where it is generated from clean sources, and it is known as green hydrogen. Hydrogen can also be produced by extracting carbon from fossil fuels, such as natural gas, and it is known as blue hydrogen.

Canada Engineering has an ambitious vision in the field of green hydrogen production by doubling or tripling electrical clean energy production in Canada, to reach 200% of Canada's electricity needs, from renewable sources, where green hydrogen can be produced at a very low cost.

Engineering Canada is also adopting the development of more research to produce green hydrogen in less costly ways, by developing chemical methods for treating water to separate hydrogen from oxygen.

Develop sustainable technology to operate flights between the Canadian regions on the moon and the State of Canada on the Earth's surface, to ensure the transportation of personnel, materials, and equipment in both directions smoothly and quickly, with zero emissions of carbon dioxide, using unique canadian technologies.

Natural disasters... $77 billion in global losses from natural disasters in the first half of 2020. While the hurricane season in the North Atlantic resulted in very expensive losses, with total losses amounting to 215 billion dollars, of which 92 billion dollars were insured.

So, Engineering Canada has developed smart strategies to take advantage of the hurricanes' very formidable energy. Instead of hurricane damage to infrastructure and consequent fatigue for taxpayers, Engineering Canada will implement massive technical and strategic plans to convert hurricanes' massive energies into electrical energy that is stored and distributed to the public.

Wi-Fi technology uses low-energy electromagnetic waves to transmit data between electronic devices. Although there is concern that radiation from Wi-Fi causes health problems, all research has shown that it is 100% safe for humans. Despite this, some individuals have reported a wide range of non-specific health problems that they attribute to a low level of exposure to electromagnetic fields (EMF). The most reported symptoms include headache, body aches, lethargy, tinnitus (ringing in the ears), nausea, burning sensation, irregular heartbeat, as well as anxiety.

Just a simple experience, which is to sleep somewhere away from all communication devices from Wi-Fi and a phone for a certain period, the person will witness an improvement in all his/her physical and psychological functions, although it is scientifically proven that EMF waves do not break chemical bonds or cause ionization in humans, unlike x-rays or gamma rays. Conversely, these waves also deteriorate quickly, losing strength as they travel away from the router. The EMF waves that are dangerous to the human body and its functions are those that are half a million times the waves currently used in Wi-Fi.

I am personally sensitive to Wi-Fi waves and suffer from them, so I combat air pollution with low-energy EMF waves, and prefer to use light waves, or what is known as Li-Fi.

Li-Fi has the advantages of efficiency and speed. It is more than 140 times faster than Wi-Fi. It is also safe and impenetrable; However, its disadvantages are that they always need a light source, and they do not penetrate barriers such as walls, as they have limited perimeter, and light waves may interfere from several sources, in addition to the lack of infrastructure - the lack of antennas to capture the light signal and translate it into communication devices and the other electronic devices - to use this technology.

The development of a hybrid communication model that uses light waves as well as low-energy electromagnetic radio waves as little as possible, in addition to use other waves at varying frequencies, is an important investment for us inCanada Engineering, to achieve a sustainable environment.

The electronics industry has developed in recent decades at an unprecedented pace, outpacing the growth rates of industries such as oil production, chemical industries, machinery industries, and automobiles.

The data of international organizations and reputable research consultancy firms, as well as the results obtained while studying the features of the global electronic industry, indicate that the electronics industry will maintain positive growth dynamics over the next decade; Opportunities to develop telemedicine, robotics, car electronics, and communications equipment will increase; One of the important issues will be regulating the production of rare earth natural resources used in the electronic industry, and minimizing their environmental impact. The search for promising sectors of electronics, which act as an additional development engine, will become increasingly relevant.

Given that there are impediments to the development of the electronics industry in many countries, such as the lack of effective application that has been the engine of the rapid development of electronics in the past half century; In addition to the insufficient funding for research and development in many countries; Not to mention the monopoly of the market, in addition to the intervention of major countries to monopolize this industry, whether by financially supporting their companies, enacting laws in their favor, or by flooding the global market with low-priced products, which hampered the development of small companies in the electronics market.

We at Canada Engineering are aware of the size and importance of the electronics market and its growth, so we have developed our own philosophy to develop a solid infrastructure for electronic industries directly related to a number of fields such as automotive electronics, medical equipment, smart home equipment, robotics, agriculture, transportation, communications in addition to moving to the surface of the moon, and other economically available sectors; Engineering Canada also aspires to move electronics objects to small cities and towns in remote Canadian provinces, as well as large cities.

The traffic problem in major cities around the world is growing day by day. Countries allocate huge budgets to solve the problem, the result comes opposite, the problem becomes more complex. There are tens of thousands of cameras on the streets of most major cities in the world to monitor the traffic in each city. Unfortunately, these cameras are only used as a reference in the event of a traffic accident or something else. It is not possible to re-view this large number of cameras to infer the different patterns of traffic flows, and to deduce solutions to them. In this difficult moment, the world stands confused and unable to find a solution, but we in Canada Engineering, simply have the magic key for solving this mystery.

The problem may be less severe in warehouses and stores, where cameras are deployed to preserve properties. These cameras serve as a reference if a theft, a damage, or a like is detected at a certain time on a particular day. Unfortunately, it cannot be used to detect theft in the first place, since so many cameras cannot be monitored. These cameras installed in stores and warehouses have recently been equipped with infrared radiation to sense any movement in the camera field, and thus the camera captures the image at the time when movement is sensed, and the storekeeper can conduct a quick review of the captured images, to discover any illegal operation.

In contrast, over a century of computers being used to store data, huge data has accumulated: the amount of information being collected every day is staggering, much greater than at any time in the past. These data is in text format, and stored in databases, and there are powerful algorithms capable of penetrating seas of these data to detect different patterns in it, but it is limited to text data saved in the form of relational databases.

There has been remarkable progress in the past two decades in the field of processing still images, especially in the field of medicine, such as radiographs and others. In addition, there has been a noticeable development in the processing of images of faces and fingerprints, which are now used in most smart phone devices.

But, in fact, the gap lies in the processing of video clips, as a person cannot review millions of videos of traffic or others, at a time when one camera produces 24 images per second and talking here about processing several million photographers and inferring the patterns of change that occur in them, to design sustainable solutions for traffic and others.

As usual in Canada Engineering, we always think outside the box, so we have adopted several ideas and research to bridge this real gap in the field of scientific research and development, and on the ground.

The nineteenth and twentieth centuries witnessed an amazing and unique development in solid-state physics, where the transistor was invented, which led to the invention of computers and ultra-fast processors, which contain tens of billions of transistors.

However, this did not meet the purpose of various applications, especially in the industrial field, where applications need double processing capacity, or the so-called supercomputing technology, where companies process huge amounts of data to improve product productivity and efficiency, such as:

#              Environment, earth, and atmosphere.

#              Applied physics: nuclear, particle, condensed matter, high pressure, fusion, and photonics.

#              Genetics, bioscience, and biotechnology.

#              Molecular science and geology.

#              Mechanical engineering.

#              Microelectronics, circuit design, and electrical engineering.

#              Mathematics and computer science.

#              Weapons and defense.

#              Data mining, databases, big data.

#              Oil exploration.

Other sectors also need supercomputing technology, such as:

#              Web-based business services and web search engines.

#              Medical diagnosis and medical imaging.

#              Pharmaceutical design.

#              Economic and financial modeling.

#              Management of national and multinational corporations.

#              Advanced graphics and virtual reality.

#              Multimedia technologies and networked video.

#              Collaborative work environments.

To obtain supercomputing technology, these companies linked computers and distributed the burden of processing applications on them, or what became known as parallel processing, which is different from concurrent processing. With the development of applications, the doubling of the amount of data and the emergence of Big Data, the process of providing sufficient processing power has become very costly. With the advent of cloud computing, companies were able to get the computing power they need at a lower price by booking the processors they need on the Internet, but this solution lacks privacy and complete confidentiality, which made it limited to commercial sector, apart from that, it is expensive for Long-term.

The military and oil production sectors have resorted to developing what are known as supercomputers, which cost tens of millions of dollars, to ensure their independence and preserve their scientific secrets. However, these supercomputers are financially expensive as they contain a vast number of processors that are connected by optical fibers to ensure the maximum speed of data transfer between processors. But in addition to the high cost, the distribution of the burden of applications on the processors is another dilemma, which made many of these supercomputers lose their luster.

Building customized high-performance supercomputers, using very low-cost Raspberry Pi processors, $100 per processor, backed by memory sticks of up to several terabytes, has become a boring chore for us in engineering Canada.

We developed the MPI library algebraically, which allowed us in Canada to build custom high-performance supercomputers within everyone's reach.

An environmental catastrophe will hit inevitably the globe, avoiding it is just a kind of pure science fiction, but we are in Canada Engineering can guide the governments towards the path of salvation.

At the time when the world seemed unable at all to make any progress to save the planet from the catastrophe of global warming, which is growing like a snowball rolling off the top of the iceberg, we are in Canada Engineering, we discovered a new source of renewable energy and developed new theories to double the production of electrical energy several times from wind energy and from hydraulic sources.

Our achievements in Canada Engineering have astonished the whole world, and made people pull their necks from the slopes to follow in unparalleled amazement Canada Engineering at the top of the mountain, to track our achievement after achievement, so that they can track our next achievement! However, the eyes are turned dazzled and weary, because everything that we have achieved so far represents the small part of solving the problem of global warming, and the stumbling part remains unresolved until now!

The seeds of the global warming catastrophe are that it is not properly diagnosed. Global warming means an increase in the temperature of the atmosphere near the Earth's surface, which leads to a rise in the temperature of the Earth's surface, including the land and sea surface. The warming of the land leads to disasters such as forest fires that that is in all countries, which in turn increases the temperature of the atmosphere. As for the rise in sea surface temperature, it leads to an increase in the evaporation rate of sea water, which leads to the saturation of the air with water vapor, which leads to the formation of many rain clouds in the lower air layers, in different seasons of the year, which leads to very heavy rain, perhaps at an untimely date. With it, rivers and dams overflow, and floods occur, as happened this summer in Germany. In addition, the rise in sea surface temperature and the rise in air temperature, together lead to the melting of ice in the north and south poles, which leads to a rise in sea level and the sinking of several cities and islands alike.

The Earth's temperature increased from -0.4°C in 1851 to 0.6°C in 1935 affected by the Second Industrial Revolution. Then the Earth's temperature rose again from 0.6 °Celsius to 1.5 °C in 2020, affected by the third industrial revolution. It is expected that the surface temperature of the Earth will increase to 5.8 ° C until the year 2100, which means, God almighty forbid, a devastating environmental catastrophe that cannot be compensated for by the globe. If global warming continues at the current rate, drastic changes in the global climate are likely to turn forests in the southeastern United States of America into grasslands. Globally, deserts may spread at mid-latitudes while the tropics become uninhabitable. At the same time, most of the frozen northern and southern regions will melt and become habitable, and this would lead to a lot of conflict in the regions of Antarctica in particular. Forests in Asia, Europe and North America will also be converted to agriculture. In addition, more greenhouse gas accumulation leads to changes in the composition and thickness of the stratosphere, which may affect the path of satellites, radio wave propagation, and the operation of satellite navigation systems. This means that global warming may bring with it the problem of disrupting wireless communications worldwide, which motivates us in Canada Engineering to find a radical solution to it.

The increase in air temperature has many factors, including the increase in the population of the globe, and the increase in industrial, commercial, and agricultural activities. For example, the electric car, which uses electricity from renewable sources, contributes to the increase in the temperature of the atmosphere through the heat of the electric car engine, which produces heat because of its operation.

In addition to the factors of human and urban growth on the rise in air temperature, there are emissions of greenhouse gases, such as carbon oxides and nitrogen oxides, mainly from the industrial sector and the heavy transportation sector. These gases accumulate in the stratosphere, which extends from an altitude of 18 km to about 50 km above sea level. These gases are characterized by their ability to absorb the infrared rays emitted by the Earth - due to greenhouse gas emissions - to form an insulating layer that prevents the passage of heat from the Earth into space, making it contribute to heating the Earth's atmosphere twice, once because it does not allow the heat emitted from the Earth to enter outer space, and again due to the high temperature of the gases themselves due to the infrared heat they acquire. If emissions of carbon oxides and nitrogen oxides resulting from four main reasons are completely stopped, namely burning fossil fuels, decreasing forest area, industrial emissions and agricultural emissions, this buffer layer may be eroded within about twenty years.

Before the Industrial Revolution, the proportions of greenhouse gases in the atmosphere remained constant. Human activity since the beginning of the Industrial Revolution, around the year 1750, has led to a 45% increase in the concentration of carbon dioxide in the atmosphere: From 280 parts per million in 1750 to 415 parts per million in 2019. So, using the vast amounts of clean electricity and green hydrogen that Canada Engineering has made available within hands will reduce greenhouse gas emissions, which will slow the pace of global warming. But the critical point is why greenhouse gas emissions do not stop completely and is there still a need to use fossil fuels that pollute the atmosphere on the one hand and produce greenhouse gases on the other, after Canada Engineering has provided enough clean electric energy and enough green hydrogen?! Where is the problem then? Why not a complete halt to greenhouse gas emissions take place?! Is it the age of fossil fuels?!

Before answering this question, I will touch on carbon air purifiers developed by several major American oil companies, led by ExxonMobil, and Chinese companies have developed similar purifiers, perhaps less efficient. Carbon air purifiers absorb carbon dioxide from the atmosphere and extract carbon, which has great economic benefits. It is used in the manufacture of cement, concrete, fertilizers, carbonated water and several food and pharmaceutical industries, and it has many uses in the industrial sector in general. Carbon trading is economically feasible, as the price of a ton has fallen from $1,000 to nearly $200 – so it becomes within hands of the consumers – due to the interest of investors in this sector. ExxonMobil has announced investments in the field of decarbonizing the atmosphere with a value of one billion dollars, to convince the American and international public opinion of the seriousness of its continued extraction of oil and its multiple uses that pollute the atmosphere and produce greenhouse gases, as it will clean the air, after polluting it, and therefore will not be a cause of global warming!

There is no doubt that here is a huge gap that ExxonMobil experts missed, but we in Canada Engineering are sure that carbon air purifiers are ineffective at all in reducing greenhouse gas emissions. These devices clean the air near the surface of the earth, and this is beneficial to human health and the safety of his respiratory system. When greenhouse gases are emitted from factories, they do not ask ExxonMobil, since it has the largest lobby in the US Congress, do they stay close to the surface of the earth or rise to the stratosphere, to exacerbate global warming! Naturally, hot gases - like greenhouse gases are emitted from factorie - are light and rise to the top, while cold gases are heavy and remain at the bottom. Therefore, ExxonMobil air purifiers will not affect the global warming problem in any way. But in Canada Engineering, we advise the major American petroleum companies, led by Exxon Mobil, to develop this device so that it is connected directly with the oil refineries and with factories, so that their exhausts are immediately recycled before being emitted into the atmosphere, and thus ensure that greenhouse gases do not leak into the stratosphere or to the human lung alike.

Praise be to God Almighty, we are in Canada Engineering direct the governments that seek carbon neutrality, such as the governments of Canada, the United States of America, Germany, and others that seek carbon neutrality, and instruct it to enact laws and regulations on factories and refineries to recycle their exhaust gases before they been emitted into the atmosphere using air purifiers, which will lead to significant decrease in global warming.

Back to the faltering part of global warming, which is still unresolved. The problem is that human civilization and urban development today are based on what is known as petrochemicals, such as mainly plastics, aromatics, fertilizers, fabrics, insulators, fibers, rubber, medicines, detergents, nylon, pesticides, adhesives, and industrial sponges, in addition to sulfur and its derivatives, resins and high-density polymers, and it is not ended by dyes or intermediate materials used in all types of industries. Petrochemicals are produced from crude oil and natural gas, and the success of these industries depends on their abundance in high purity and low prices.

For example, an electric car that uses electricity from renewable sources, contributes twice to the increase in the temperature of the atmosphere, once because of the heat generated by its engine during operation, and once because all its parts are manufactured from petrochemical products, producing greenhouse gases, during their manufacture!

The gases emitted due to the manufacture and production of petrochemical products constitute more than 50% of the greenhouse gases in the atmosphere, and the heat emitted due to the production of petrochemical products constitutes the main source of high air temperature.

The solution is for the world to abandon petrochemical products, which seems impossible; Or find a way to manufacture alternatives that do not produce greenhouse gases. Are there any alternatives?! The world, for example, will still need asphalt to pave the way, and refurbish it as it erodes.

The traditional plastic industry emits large amounts of greenhouse gases. A new carbon technology is being developed to manufacture polypropylene, a versatile plastic. Many chemical industry companies have been interested in the technology of manufacturing polypropylene from carbon dioxide. Although the theoretical foundations of this technology have been known for decades, the real obstacle was the discovery of a catalyst capable of accelerating and completing the chemical reaction needed to manufacture this type of plastic.

There is another direction in which the American company NOVOMER seeks to produce plastics from an unconventional source, as it works to convert carbon dioxide into polypropylene carbonate for use in the preparation of polyurethane used in adhesives, coatings and as a sealant, to replace these products with traditional polymers made from petroleum. It depends on the polymerization of carbon dioxide and epoxides, so that the resulting materials contain 40% of their weight in carbon dioxide.

These researches have been going on for several years, and it is still ongoing, knowing that new plastic products are less efficient than those produced from oil and natural gas in the traditional form; It goes without saying that there are other products such as asphalt, maintenance grease, and others that have no alternatives so far.

The lack of a solution to the greenhouse gases resulting from the petrochemical industry makes the carbon neutrality slogan raised by the governments of Canada, Germany, and the United States of America a kind of pure science fiction, or just an electoral slogan with a captivating luster that catches the eye!

Praise be to God Almighty, we are Canada Engineering have the Joker, we are Canada Engineering think outside the box, and therefore we have the solution. we are Canada Engineering will save the world from the dark tunnel that is preparing to enter it against its willing, the tunnel of exacerbation of global warming, which may be the last tunnel in human history. we are Canada Engineering will save humanity, been supported by God Almighty willing, we are Canada Engineering will lead humanity to be safe.
