Where Is Mining Common And Uncommon In Canada

For those familiar with mining, have you heard the term coal tattoo?

"Natural" tattoos
According to George Orwell, workers in coal mines would develop characteristic tattoos owing to coal dust getting into wounds. This can also occur with substances like gunpowder. Similarly, a traumatic tattoo occurs when a substance such as asphalt is rubbed into a wound as the result of some kind of accident or trauma. These are particularly difficult to remove as they tend to be spread across several different layers of skin, and scarring or permanent discoloration is almost unavoidable depending on the location. In addition, tattooing of the gingiva from implantation of amalgam particles during dental filling placement and removal is possible and not uncommon.

Is there anyone who lives in a mobile house or a caravan in Canada, especially during winter?

There are a lot of people in Canada who live in mobile homes year round. You can buy a sufficiently insulated mobile home to be quite comfortable in the winter. If you have a natural gas supply, it can be quite cheap to heat.Since you use the word, “caravan”, I assume you are European. When I was in Europe they talked about their problems with the “Romani” who lived in “caravans” all year round. They asked me how many of them there were in Canada, and I had to tell them I had no idea. Nobody has any idea, we don’t count them.If you live in a “caravan” i.e. a trailer in Canada, you would be living exactly like a lot of other Canadians. If you were a “Romani” you would look no different than a lot of other Canadians since many Canadians have darker complexions. You would sent your kids to a Canadian school where they would blend into the cultural matrix and be just another Canadian kid. We are really good at Canadianizing immigrants.I live in the Canadian Rockies, and I can remember leading a tour of French from Paris through the mountains. Being English Canadian, I couldn’t tell the difference in accents, so I didn’t know they were were from France until they told me they were horrified to learn that a lot of French Canadians in the area were living in tents in the woods for the summer. My reaction was, “They’re French Canadian, that’s what they do if they can’t afford to pay rent.” Apparently it’s not very common in France, but in Quebec it’s part of their tradition.It works in Western Canada, too. 80% of the people in our local campground here in the Canadian Rockies are French Canadian and most of them are here for the summer, trying to learn English.

Is mining deuterium for fusion reactors from the deep ocean feasible in the long run?

But there's no need at all to go to the bottom of the ocean to obtain Deuterium.Deuterium is present in seawater at a concentration of about 330 parts per million. Extracting it is a pretty straightforward, if expensive process. I believe heavy water (D2O) costs on the order of US $7000-10,000 per kilogram.The fusion reaction that goes at the lowest possible pressures and temperatures is the D+T (T=tritium) reaction, however, the D+D reaction will go only about 1/10,000 as fast as the D+T for a given temperature and fuel concentration.So the real problem is to find, or rather, since tritium is very rare, to manufacture the tritium. This can be done either by neutron capture on deuterium, in a heavy water moderated fission reactor, which is a relatively inefficient but low energy cost process, or by neutron activation of Lithium-6, which yields about 5 MeV of energy per tritium nucleus produced, while D+T fusion yields about 17 MeV. Both of these methods are currently used to produce tritium.The energy produced from fusion of a kilo of deuterium would be worth far more than the cost of the materials, and in the long run certainly worth more than the cost of building the reactor and energy extraction mechanism (though these are not trivial problems, to say the least.)So if, and this is a very big if, fusion reactors were practical, then yes obtaining fuel for them would be feasible in the long run, and cost effective. But so far fusion reactors are nowhere near to being practical.

What are some natural resources commonly found in Canada?

Canada is known as the “bulk barn” of the world. It is home to many resources.These resources fall into three categories: energy, mineral and timber. Energy resources include natural gas, crude oil, crude bitumen (oil sands) and coal. Mineral resources include gold-silver, nickel-copper, copper-zinc, lead-zinc, iron, molybdenum, uranium, potash and diamonds.If you are also wondering why Canada is home to many resources, it is because it is the second largest country in the world (after Russia),and has the worlds largest proportion of fresh water lakes. Canada also has a very small population compared to other countries that are similar in size. This is why we are able to share most of our resources.Hope this helped!

Is a city-state and a country the same thing? Please explain.?

City-State is a sovereign state consisting of an independent city and its surrounding territory (outside its borders). It serves as a leader of religious, political, economic, and cultural life. Today, only a handful of political entities reflect the features of city-states, namely Singapore, Monaco and the Vatican City. Key words: sovereign, independent cities.

Country is a sovereign territory that usually governs within its borders.

What is the meaning of this Urdu phrase "Lahaul valla kuwwat"?

This phrase must have come to Urdu from Arabic.

"La haula wa la quwwata.." (no might nor force..)
This is half the original sentence, but it is very often that people just say this first half and the other half would be implicit.

The full sentence is "la haula wa la quwwata illa billah" (There is no might nor force except through God."

Hope this has helped.

Peace-salaam.

What's the best specialization after finishing a civil engineering degree? My professor told us to specialize in oil and gas engineering. Is it advantageous to take up a Master's before proceeding to the specialization?

There is no "best" specialization. The most important thing is for you to first figure out what specialization interests YOU and THEN figure out where the market is. For example, it will always be possible to be a successful structural engineer if you decide you are really passionate about it. It might be more difficult to find a job and you won't be designing really avant-garde buildings for many years, but the world always needs the people who will struggle for those types of jobs. If you are asking where will you make the most money, then go into finance (i.e. NOT civil engineering). If your question is more about where the largest growth in the civil engineering industry is, then yes- I'd generally agree that the energy sector is a good place to be. However, there will always be a need for structural engineers, water engineers, transportation engineers, etc. A Master's degree also depends on what specialization you decide to go with. My personal philosophy is that you should only get a Master's degree if you are sure it will help you get a specific job or get more in depth into a topic you are really interested in. Some examples of reasons to get a graduate degree:Structural engineering positions almost always require a Master's degree and the option to eventually obtain a Professional Engineering licenseIf you want to move to a different country, many times people will do a one-year graduate school program in that country. If the energy sector is booming as much as much as sources say it will be, you're probably going to be learning most of your job with your first company, and you won't actually use much of what was taught to you in school. They just want to see an engineering degree. Why waste the time and money on another few years of school? If you have been working for a few years, and realize you don't actually like the specialization you chose, graduate school can be a great way to jump into a slightly different field.

What should I study or learn if I want to be a data analyst for a software company like Quora, Zynga, Airbnb, etc.?

When I was on the analytics team at Airbnb (2011-2012), we looked for the following:1. Research design/methodology - Ability to set up experiments properly, with careful attention to control groups and confounding variables- Knowledge of basic statistics techniques and concepts (regressions, ttests, significance, etc)- Ability to delve into open ended problems and find trends in huge sets of data- Understanding of all the caveats and complications of research without getting so bogged down in them that it takes months to get results2. Tools to manipulate data (programming ability, sql, statistics tools, etc)- Python, Ruby, or another similar programming language- R, STATA, SAS, or some other statistical programming language for analyzing data- SQL or similar querying/manipulation language, understanding of fairly complex joins, nested queries, etc- Excel can be useful but details can probably be learned as needed (personally, I don't think I've ever used a pivot table in my job because I use other tools to combine data)- Hive, Hadoop, etc. are really useful, albeit not essential for getting hired (but would mean a lot more than detailed knowledge of Excel, which I would assume any smart person could pick up as needed)3. Ability to interpret and summarize results broadly for technical and non-technical audiences4. Any other special skills, such as data visualization, machine learning, advanced statistical techniques, etc.At ClassDojo, we are at an earlier stage, and the data is in JSON instead of SQL, so there is even more need for everyone to program.  I spend 90% of my time getting data in place in Python before I can do any actual analysis or visualization (in Python or R).Edit: For a much more complete answer, you can view this curriculum that I wrote using free online materials:  Data Analysis Learning Path by Claudia Gold | SlideRule
