# Climate Change/Mitigation Strategies

In this section, we assume anthropogenic climate change is well underway and examine what individuals and social structures can do to slow or reverse the trend.
It is consensual that at present all strategies to address climate change in a global scale will be extremely infective, not by design but for failure to comply and commit to them, and extremely costly, especially due to the first reason. If measures are not taken simultaneously by all the unbalance will aggravate the impact on those that will attempt to implement them.

## Community contributions to mitigation

This section highlights some current thinking about how communities might deal with a changing climate. These include encouraging people to live closer to where they work, building up (not out), increasing use of public transportation, increasing recycling programs, more efficient use of water resources, more renewable energy sources, and even "green" urban planning.

## Individual contributions to mitigation

Here we discuss how personal conservation can help to limit greenhouse gas emissions.
* Principles
* In the office - computers, printers, windows, etc.
* In the home - appliances, water use, etc.
* Transport - gasoline, diesel, biodiesel, hybrids, and even bikes/walking.
* Lighting - compact fluorescent bulbs, LEDs, OLEDs
* Heating and Cooling
* Alternative Energy - Roof-mounted solar panels, personal wind turbines, etc.
* Food - Adopt a balanced diet, trade some of the meat, milk, eggs based foods for fish, vegetables, and cereals.
* Sustainable Development

## How societies/countries can reduce emissions

Governments are now aware and intend to take action to reduce greenhouse gas emotions, these are several areas that can contribute to it.
* Carbon Sinks - including sequestration
* Public Transport - efficient urban planning, trains, buses, and shared resources
* Renewable Energy - solar, wind, tidal, geothermal
* Nuclear Power - fission now, fusion later?
* Fossil Fuel Economics - Hubbert's peak and making it a plateau (maybe)
* Natality - Promote family planing and reductions of population.

# Climate Change/Mitigation Strategies/Home

* Only fill the kettle with the minimum amount of water. Never boil more water than you need. If the kettle is on for only 2 minutes per boil then you emit about 100kg of CO$_2$ every year. If it's on for 4 minutes per boil then you emit 200kg of CO$_2$. (maths: 2kW x 365 days per year x (2minutes / 60) hours x 10 times per day x 0.43 kg of CO$_2$ per kiloWatt hour = 105 kg of CO$_2$ per year)
* boil water in the microwave instead of the stove top.
* Turn the cooker down as low as you can. For example, if you're boiling an egg then put the gas / hob on full until the water boils, and then reduce the heat. The water will continue to boil but you'll be using less energy.
* Next time you need to replace a light bulb, use a fluorescent lamp instead of an incandescent lamp. A 20 watt fluorescent lamp gives as much light as a 60 watt incandescent lamp — an incandescent lamp converts only 10% of its power into light; most of the rest gets converted into heat. (But because of this, switching to a fluorescent lamp may make the room feel colder.)
* Reduce the number of lamps in a room. One 60 watt lamp may provide sufficient light instead of two 40 watt lamps.
* Consider solar power. But do the homework in terms of cost and benefit before making a decision.
* Use Energy Star-compliant and similarly energy-efficient appliances.
* Use rechargeable batteries. This reduces the number of dead batteries to be trashed, and hence the amount of hazardous chemicals in landfills.
* If your home computer doesn't need to be 'always on' (e.g., it is not used for work), consider consolidating your computer usage to only a few hours every day. Turn the computer off the rest of the day.
* Use draft instead of air conditioning during hot days.
* Plant a tree(s) so shadow will reduce heat during hot days.
* In the winter, set your thermostat at 68 degrees in the daytime and 55 degrees at night. In the summer, keep it at 78.
* Showering uses up 40% less water than a bath.
* Install low-flow shower heads and faucet aerators.
* Wash full loads in your dishwasher and use short cycles for all but the dirtiest dishes.
* Set the appropriate water level for different size loads in your clothes washer, wash in cold water when practical, and always rinse in cold.
* Don't use dryer to dry you clothes after washing. Let them dry themselves on hangers or rope in natural way.
* Wrap your water heater in a water heater blanket, especially if it's located in an unheated part of the house. This prevents heat loss through radiation.
* Opt-out from unwanted mailings: credit card offers, free newspapers, catalogs, advertisement, etc.
* Use Internet for latest news or library for newspaper/magazine articles.
* Bring reusable bags with you when you need to visit stores.

## "Green" Roofs

"Green roofs" refers to growing plants on the top of roofs of buildings. There are several different methods for implementing green roofs. Green roofs have been wide spread in Europe and especially in Germany. Now the concept of green roofs is starting to spread in the USA. Egypt has started a green roofs initiative as well but uses a different method for implementing green roofs.

### Benefits
#### Space Efficiency

    Except from keeping rain and sun off a building's occupants, roof space is essentially wasted. Green roofing makes use of this wasted space.

#### Air purification

    Plants absorb pollution from the air. Growing plants on the roof of a building contributes to improved air quality in the surrounding city. Obviously, green roofing will have a larger effect on air quality if it is employed in a widespread manner.

#### Aesthetic appeal

    Even urban humans generally retain an aesthetic appreciation for being surrounded by plants. Green roofs can add a serene communal space to a building.

#### Food supply

    Green roofing can be used as a source of vegetables and other edible plants.

## Solar Panels

The solar panels can help to produce energy for a house, which can help to reduce or eliminate the cost of electricity.
They are best used in zones where there is a lot of sunlight, such as in the tropics or in very hot zones.
# Climate Change/Mitigation Strategies/Food

* Drink tap water whenever possible. Avoid bottled one and soft drinks.
* Buy just enough perishable goods so that they are used by their expiration date. Avoid buying too much and having to throw them away after their expiration date.
* Prepare food yourself. Don't buy deeply processed food, since it consuming evolve unnecessary warm/freeze stage.
* Take food with you from home to work in reusable container if you could. This will reduce amount of transportation if you don't have place to eat in walking/biking distance and also reduce amount of waste on packaging/thrown away kitchenware.
* Buy locally grown food. This will reduce transportation toll on environment
* Buy organic food if you have such choice. Organic food production doesn't allow usage of chemicals pesticides, herbicides, fertilizers.
* Buy seasonal fruits and vegetables.
* Reduce meat consumption. Meat production is ineffective way of producing food and also cause pollution with manure, methane as green house gas. Industrialized meet production also means animal cruelty: animals are not raised in natural environment; in many cases they are not feed with food they used to consume in nature; animals are not allowed to follow their natural instincts and kept in small space.
* Plant vegetables and fruit tree if you have land to work on. Some folks even grow hens for eggs and meat in city!
* Explore your neighborhood area for fruit trees on public or abandoned land to peek fruits. Sites such as http://cityfruit.org are good resource for finding such trees nearby.
* Give away your excessive vegetables or fruits harvest to your friends, neighbors, colleagues, community.
# Chess Opening Theory/1. e4/1...e6/2. d4/2...d5/3. Nd2/3...Be7

This is the Morozevich Variation in the French Defense. This is a sideline which has the idea to force Ngf3, not a comfortable place for the king's knight as he would rather be tucked at e2 to protect the d pawn. Hence, 4.Bd3 is the main line to delay the king's knight to establish itself on f3 and force and Nf6 and e5, to possibly transpose to the mainline.
# French Defence: Tarrasch Variation / 3....Nf6

Just like in many other variations of the French Defence White decides to get some space advantage by playing e5.
Now Black's Knight is attacked and Black's should retreat it by playing 4....Nfd7. In a few games Black players have also tried 4....Ne4, but after White captures this knight on e4 black may end up with a weak pawn on e4, so this is dubious.

# French Defence: Tarrasch Variation / 3....Nf6

This position has some similarities to the Steinitz Variation of the Classical French, however, with their Queen Knight on d2 (instead of c3) White will find it easier to defend their center pawns.
Having the option of supporting their d4-Pawn by playing c3 certainly is a good thing to have, and if things get worse, White can also use both knights to defend d4. In this variation Black will find it difficult to undermine White's pawn center successfully, at least if they try doing so in a classical / stereotypical way. After Black's 4. ... Nfd7 White has several ways to play, with 5. Bd3 being the most common choice: White wants to develop this bishop to a very good diagonal - before they must play Ne2 (in response to Black's upcoming pressure on d4.) 5.f4 is a good alternative for White, which overprotects the e5-Pawn and makes it more difficult for Black to create pressure against e5 (e.g. by playing ...f6). Moves like 5.c3, 5.Ne2, 5.Ndf3 or 5.Ngf3 are played less often, but aren't bad either.

# French Defence: Tarrasch Variation / 3....Nf6

Seeing that White's center pawns on d4 and e5 restrict Black's options of developping their pieces, here Black usually decides to battle White's pawn chain by playing 5...c5.

# Classical variation

Because Nf6 is no longer pinned, Black threatens to win the e4-pawn. The attempt to defend the e4-pawn, e.g. by 5.f3?! or 5.Bd3?!, will still lose the pawn, because White's Bg5 is not defended, so Black can simply play 5...Nxe4! and win a pawn (6. Bxe7 Nxc3 7. Bxd8 Nxd1 8. Bxc7 Nxb2 -/+). That's why White either plays the e4-pawn to a safe square (Main Line - 5.e5), or eliminates an attacker of e4 (5.Bxf6). A safe alternative is a transposition to the Exchange Variation (5.exd5).

# French Defence: Tarrasch Variation

The move Nd2 prevents Black from entering the Winawer (3.Nc3 Bb4). The knight on d2 exerts no pressure on d5 and may lead to slower development of white's pieces but the move is solid and leads to games of a more positional nature than its main alternative of 3.Nc3.

# French Defence: Tarrasch Variation

"3...Nf6 is the most tactical option for black. He doesn't play for a solid position but prefers to complicate matters with dynamic play. Very interesting positions arise, with rich play and fascinating ideas for both sides (GM Andreas Tzermiadianos)".
For those Black players who don't want to play with an isolated d-pawn (at least: not yet), the 3....Nf6 variation is a good alternative to 3....c5.

# Chess Opening Theory/1. e4/1...e6/2. d4/2...d5/3. Nc3/3...Nf6/4. Bg5/4...Bb4

The McCutcheon variation first became well-known as the result of an 1885 simultaneous exhibition game played in New York by World Champion Steinitz as White against John Lindsay McCutcheon, a lawyer from Pennsylvania. McCutcheon won convincingly in just 28 moves, and thus brought attention to the variation. It is still (2024) considered to be a completely sound defense for Black. There is no record of a previous game with this variation, so it is possible (though impossible to prove) that McCutcheon created a true novelty.

## Change in Variable

A Change in variable is a term used to express the difference between 2 variables . Let $\Delta$ represents Change in 2 variables $x_{0}$ and $x$ then
    $\Delta x=x-x_{0}$
    $x=x_{0}+\Delta x$
If there is a function $f(x)$ such that when $x$ change by an amount $\Delta x$ the change in function will be
    $\Delta f(x)=f(x)-f(x_{0})$
    $f(x)=f(x_{0})+\Delta f(x)$

## Example

There are 2 points (1,3) (5,7) then
    $\Delta x=x-x_{0}=5-1=4$
    $\Delta f(x)=7-3=4$

# English-Hanzi/Osteoporosis

Special:search/bone loss prefix:English-Hanzi/
Osteoporosis can be prevented by leading a healthy life. It is important to have a good calcium-rich diet. Lifestyle modifications such as quitting smoking and doing weight-bearing exercises can prevent the development of osteoporosis. The more physically active a person is, lesser the chances of having osteoporosis. The advantage is that there are medications which can help in increasing bone density. But the most important aspect is to manage the deficiency of calcium and vitamin D in the body which works to strengthen the bones.
可以 通过 健康 的 生活 来 预防 骨质疏松症。重要 的 是 要 有 富含 钙质 的 饮食。生活方式 的 改变，如 戒烟 和 做 负重 运动 可以 防止 骨质 疏松症 的 发展。身体 活动 越多，骨质疏松 的 可能性 就 越小。幸好 有 药物 可以 帮助 增加 骨 密度。但 最 重要 的 是 解决 身体 缺乏 钙质 和 vitamin D，其 作用 是 强化 骨骼。
Dairy products like milk, yoghurt, cheese etc are rich source of calcium. Besides these, soya, leafy green vegetables like spinach, kale, turnips, and collard greens, cereals such as raisin bran, corn flakes, orange juice, soybeans, soymilk etc are good sources of calcium.
乳制品如牛奶，酸奶，奶酪等是钙质的丰富来源。除了这些，大豆，绿叶蔬菜如菠菜，羽衣甘蓝，蔓菁和散叶甘兰，谷物如葡萄干麸皮，玉米片，橙汁，大豆，豆浆等是钙质的好来源。
Vitamin D helps the body in absorbing dietary calcium. It is insufficient in diet and synthesised by our skin under UV rays of sunlight. Therefore, sun bath is very important for our body. Women tend to use skin lotions for protecting their skin from sunlight. It should be avoided sometimes so as to give body adequate vitamin D.
Vitamin D有助于身体吸收膳食钙质。靠饮食不足够摄取vitamin D，我们的皮肤在阳光下的紫外线可合成vitamin D。因此，晒太阳对我们的身体非常重要。妇女往往使用护肤液保护她们的皮肤减少阳光照射。应该适当晒太阳，使身体有足够的vitamin D.
