Advice 2 : How to distinguish a zero and the earth

How to distinguish between zero and "land" - this issue can occur if you have taken it upon themselves to do something in the house with electricity, but do not know how to connect the three-core cable. Of course, working with electrical networks requires caution, knowledge and some skill.

The first method, which, however, does not give you 100% guarantee correct results is to look at the color of your three wire cable. Usually, if electricians who did the wiring in you house, know the standards, they leave the ground on the yellow-green wire. Let's see if you have one, this is most likely a ground.
For the second method get a working cartridge and a light bulb at 220 volts. A screwdriver-indicator to find the wire phase and connect it to one of the contacts of the cartridge. The second contact holder alternately connect the remaining two wires. If the bulb glows, the wire is zero. Accordingly, the third wire (the rest is not connected to the cartridge) to the ground.
If the bulb does not light, the wire that is connected to the cartridge is grounded. Be careful, if after this procedure, you have lost the light in the apartment, but it can occur after connecting to the cartridge ground wire, so you have RCD (residual current device). If so, find it (it is similar to circuit breaker but it has a test button, button "T") and put the lever in the topmost position.
Because the cartridge is under tension when performing all operations, be extremely careful that you are not electrocuted. If you are far from electricians, call a professional and let you will do everything you need.

Advice 5 : How to distinguish a synthetic oil from mineral

Currently, the automotive accessories market is huge, motorists can choose for your car any product depending on their needs and capabilities. But how to navigate among such a range? For example, when choosing motor oil, the question may arise which one is better for your car? There are synthetic and mineral motor oiland synthetic blend. Depending on your goals and situation, you need to choose a more suitable. So what is the difference between oils?
How to distinguish a synthetic oil from mineral
You will need
  • mineral motor oil;
  • synthetic engine oil;
  • - consultation of the dealership.
First, we need to focus on your car. As a rule, manufacturers of certain brands often provide tests of the mechanisms their cars. Based on this, they often give advice on the type of oil that best fits this type of engine. Dealers service centers can advise you, choosing what to make your model the right products
It is necessary to take into account seasonality and certain properties of motor oils. So, mineral oil is natural, that is, has a basis in her original form after refining. A synthetic created by a synthesis of the natural substrates with so-called additives additives each of which has certain properties. Creating a synthetic basis was required when mineral oil isused for aviation purposes, began to freeze at low temperatures. Under the influence of chemical molecules natural base has acquired new properties — resistance to temperature changes. It was invented synthetic mineral oil. The ability to maintain its original properties (viscosity, yield stress) when the external environment is one of the main differences between synthetic oil from mineral. Due to this property, those who are in the winter, use synthetic oil, the engine starts easier. Because at first, he warms up, then overheats, then cools down — and synthetic oil at this time is operating as usual.
The second distinctive feature of synthetic oil is its life. Filling your engine with mineral oil, you have to understand that to change it you will have more, as it quickly becomes unusable. It should be noted that it is best to use motor oil in the same category and manufacturer. Mixing oil is not desirable. The best option would be to either stock up on Pro stock one oilm or a mix of different characteristics (viscosity, labeling) oil one manufacturer than of the same type (mineral or synthetic) of different companies. Since the production technology is different, the oil may coagulate, which will not result in anything good for the engine.
Useful advice
Also synthetic oil can reduce engine wear, increases power, makes it easier to start a cold motor in the winter and also to save fuel. Semi-synthetic motor oil combines quality mineral oils and synthetic. They differ from synthetic because they are composed of a smaller number and concentration of additives. Mineral oil generally wins in the price index. Usually it is half or two times cheaper than the synthetic oil.

Advice 6 : How to distinguish warm colors from cool

The human eye perceives the surrounding world of color. Shades of colors are divided into warm and cold. This division has a practical value, for example, when writing paintings, painting historical miniatures, cosmetics. However, many admit that they can't tell a warm color from the cold. How to learn this?

They will be "warm" or "cold" depends on what and in what proportions they mixed the base color. For example, orange is warm because it is obtained from the warm primary colors of red and yellow. Blue, by contrast, is always cold, as it is based on diluted blue. Green is traditionally considered neutral because it is formed by their blue and yellow, but shades of green, dominated by one of the colors belong to the warm or cold spectrum depending on the dominant color.
Warm colors evoke associations with summer, sun, fire, and cold with winter, snow, ice. At the basis lies the warm shades of yellow, the basis of cold is perceived as white. If you susceptible to the influence of colors, you'll notice that looking at a warmer shade, you feel a surge of energy, excitement, and looking for a cool, calm down, start thinking rationally. Spatial cool shades perceived to be more distant from the viewer than are warm.
Practice mixing primary colors to better determine how is a particular color or shade. To do this, take the jar with red, yellow and blue gouache and a sheet of landscape. As a visual aid, use the chromatic circle, examples of which can be found on the Internet. Learn to determine the composition of the color accurately on the eyes.
Keep in mind that the perception of shades is largely influenced by the color of their environment. For example, if you put two patches of color "cadmium red" and "Carmine", the first will seem warm and the second cold. A similar example can be quoted from other parts of the color spectrum: a neighborhood with blue makes purple seem warmer, the neighborhood red – cold.

Advice 8 : How to distinguish organic vegetables from the vegetable nitrates

Nitrates – salts of nitric acid. They are in every living organism, so their presence in the human body is perfectly natural and is no harm. But the excess of these substances is dangerous to health. Basically, the nitrates enter the body from foods of plant origin, primarily from vegetables. Therefore, it is important to know how to distinguish the useful vegetables from nitrate.
How to distinguish organic vegetables from the vegetable nitrates

How to determine the naturalness of vegetables

First and foremost, you want to track seasonality. If the season, for example, of tomatoes, has not yet come, and you see them on the shelves, so they imported. And in order to increase their shelf life, they add nitrates. Find out on the duration of the harvest seasons of your country and not be fooled.

Chemicals are added to the vegetables to keep their appearance. Therefore, if the products look unnaturally flawless, fresh and strong, most likely, they will not benefit you.
Remember, lice, and flies attracted by the aroma of natural products, so they completely ignore nitrate.

How to avoid mistakes when choosing vegetables

When choosing tomatoes pay attention to their color. If they have an orange tint, it means they were grown with application of fertilizers. Then try the tomato to the touch. Push down with your finger: if the skin does not burst and it left a dent from your finger, rather, the product is full of nitrates.
Sometimes the tomatoes are sold directly on the branches. Hemicalname tomatoes are nice and fresh, they do not detach from the branches, even if they begin to rot inside.

When choosing cucumbers move your hand over their surface. Soft, thin, easily erasable spikes talking about the genuineness of the product. Rude thorns and dark green skin means that cucumbers grew on nitrate plantations. If there is no smell of pickles to buy and not worth it.

Journalists held a special experiment in which revealed that the majority of cucumbers on the market and in supermarkets don't smell, and therefore taste.

When choosing carrots, note the color. Natural fully orange, it lacks the green and yellow specks.

When selecting cabbage do not think that the black dots and stains on it indicate the absence of nitrates. On the contrary, dark spots on leaves is a fungus that develops on nitrate in vegetables.

Test the cabbage. Leaves natural usually dense. The base of the leaves, the stalks should not be fat.

Potato tubers grown without added chemicals, are also recognized in appearance and to the touch. Potatoes with green spots suggests that the tubers had spent too much time in the sun. These stains are a sign of the presence of toxic solanine toxin produced in plants and are very dangerous to human health even in small doses.

Natural potatoes should be firm and elastic. Tubers, containing a large amount of pesticides and nitrates look smooth and even, and they feel quite soft.

If you press on the potatoes with a fingernail, you should hear the crunch. If the nail enters the tuber without sound, it means that such potatoes grown on mineral and nitrogen fertilizers.
