Nose as Medicine for Fatigue and Dizziness

We have a nostril on the left and right, that's for sure. Does the same function for inhaling and dispose of breath? Actually, no and we can feel the difference. Right side represents the sun, out of breath, and the left represents the moon, out cold. That's our unique nose that in fact not much noticed.

If dizziness, try to close your right nostril and breathe through your left nostril and do think - about 5 minutes, the headache will be cured. If you feel tired, close your left nostril and breathe through your right nostril. Perform back.

Soon, you will feel refreshed. For your right nostril hot issue, so easy to heat, release the left nostril cold. Women breathe more with their left nostril, so calm down easily. Men breathe more with the right nostril, so easy to anger.

Did you ever notice when you wake up, whichever nostril breathing faster? The left or right? If the left nostril breathing faster, you will feel very tired. Close your left nostril and use the right nostril to breathe, you will get refresh quickly. The way it should be taught to children, but the effect will be more effective if applied to adults.

It's an experience, try the tips apply without these side effects. Many others have tried and succeeded. It is a natural therapy, such as taking medicines for a long time may have side effect. So why do not you try? Practice the correct ways of breathing therapy (interesting and out of breath), the condition of your body will be very relaxed.

Pelawan Wood (Tristania Abavata) & Fungus

Pelawan Tree
Pelawan wood is said to only grow in the forests of the Bangka island, particularly in the interior of the island. Ax form and color and artistic make this wood has its own characteristics. Pelawan wood is very special for the people of Bangka. In the era stove is still a luxury item, pelawan wood is the main ingredient in the Bangka firewood stove to cook, who sold a bonded-bound trucks. Although now retired as firewood, pelawan wood was still flying as useful wood and high economic value because of the honey produced by bees who suck the nectar of flowers which are honey bitter pelawan tree distinguished prime quality for the health of honey reputed contrarian. Also species of fungi which grow on wood umbrella is very popular as well as quality and high nutrition in Bangka language who were known as Kulat Pelawan (Pelawan fungus). Mushroom or black fungus price is expensive on the market. Now, worth about Rp 400 thousand per kg and it was very tasty after cooking curry coconut cream or sauteed. 
Pelawan fungus is one fungus that expensive for the size of country boy bags. Because of scarcity, supply of pelawan fungus could not be ascertained.
Pelawan fungus
In its habitat, the pelawan fungus occurs only once a year in the rainy season. Mushrooms only grow at the foot of the pelawan tree, one of the rare tree species found in the forests of the island of Bangka. While still fresh, it colours red burgundy.
To get a
pelawan fungus, they must hunt to remote forest. They get it too chancy. If lucky, they could gain 3 kg a day of hunting.
When you buy a
pelawan fungus, choose clean. Therefore, the location of the fungus at the foot of the tree caused it in direct contact with soil. After all, mushrooms are covered with soil will be heavier in the scales.
Residents of Bangka cook it thoroughly. Mushrooms are washed thoroughly and boiled until the meat is first cooked and tender mushrooms. In cooking
soupy, pelawan fungus inserted after stir spices, coconut milk before casting. Plaintiff cooked first because harder. In Bangka Belitung, soupy dish side by side with boiled cassava leaves and shrimp paste.

Observing Solar Eclipses Safely and Simplified

Solar eclipse events often make a scene, yet it is common natural phenomenon, although considered somewhat rare. One cause of the uproar is concern about the safety of the eyes, the fear that led to blind to see the eclipse.

Pupil

As the diaphragm in cameras, the human eye has a pupil that can widen or narrow to measure the amount of light entering the eye. In the dark atmosphere, the diameter of the pupil dilated to 8 mm in order to collect enough light that lets people see in the dark. In the summer, shrank to 2 mm in diameter, was even able to shrink to about 1.6 mm when faced with blinding light.
But by the pupillary light dosing no limits, no blocking power beam of sunlight is so intense. If calculated, the direct light from the sun should be attenuated 50,000 times in order to be safe for the eyes, made the original strength of 0.00002. Otherwise, people are desperate to challenge the sun is likely to be blind.
Therefore, daily sun glare beam always be avoided. But when the eclipse comes, people get interested to observe the sun's face being turned into a crescent. Forget the mainland was possible, unaware about the dangers.
Because at the time of eclipse, solar beam was blocked in part by a month so that nature becomes dim and pupils were dilated. Right at the top when people look up to stare the sun, the pupil has not had time to react, when the sun's surface brightness remains the same with the enormity of the daily, the shrinkage in size only to form crescent. It's certainly an enormous danger that threatens blindness. The more so if looking through binoculars, camera or other optical instrument that is not modified, because there is a lens that focuses light on it and greatly increases the danger.   
Do not ever see the solar eclipse with the naked eye, especially with binoculars or cameras that are not equipped with a special equipment.

Box

Kotak Pemantau Gerhana
Eclipse Monitoring Box

No need to worry, there are a number of safe ways to observe the event, not necessarily once a year stop in the same region. The principle that is widely used is not seen directly but watched the image of the sun on a surface. As another way, the sunny weather is certainly needed. A tangible example of a simple cardboard box that can be made yourself (see picture).
Field over an area of ​​approximately 30cm x 30cm were given a small hole (often called Pinhole) In diameter about 1 mm at a distance of 5cm from the edge. Through this hole, the sun will break through to form the image on the surface in the field below. The higher the size of the box, the image of the sun getting bigger. But for the sake of practicality, it is enough if the high box between 50 to 80 cm.
Furthermore, on the edge of the field of widening the hole created as a place to taste for both eyes to peek inside the box. In use, with his back to the sun, the box held her eyes peered inside. Box dimiring-tilt slightly to find the best direction that produces the image of the sun in the field below.
Two reasons that make this box safe. Firstly because of the small hole to allow only incoming bit stream sun. Both because we are observing with his back to the sun, keep the eyes from the spotlight of the sun.
The same principle is also found in other places. Those who do not have time to make the box can be prepared under the trees that still get a little sunlight, so that in normal circumstances reveal bright dots on the ground. Consider the tiny dots that, when the solar eclipse into crescent shape. If the wind blows the leaves shake, sickle-bright crescent funny even then moving around.

Why Animals Can Walk On Water?












More than 1,200 animal species have evolved the ability to walk on water. Not only small animals such as insects and spiders, some reptiles, birds and even mammals are also developing this talent.

Although there are many techniques for walking on water, but are categorized in two patted and rolled, according to the paper in 2006 from the journal Annual Review of Fluid Mechanics.

Small animals into the categories slide. Insects, like a water spider, can glide or run faster at the surface of the water. These creatures are quite small and its weight can be supported almost entirely by surface tension, which is a relatively weak bonding strength of water molecules together.

For these animals, gliding through the water similar to how humans can be lifted in the trampoline, according to John Bush, a mathematician at the Massachusetts Institute of Technology who specializes in fluid dynamics.

When walking on water, insects or spiders hit the water, his legs bent and damaged surface, but not until the break. Surface and then bounced back, pushing upward.

Surface tension makes power like that might happen. Water molecules were attached to other water molecules around it, in all directions.

However, water-resistant leg is also required. It has a microscopic layer of dense hair on their legs, which can be coated with water-repellent wax. Or hair trap from the air cushion around their feet.

"Without these adaptations, the water will soak the feet like sinking through the trampoline," said Bush.

For larger animals, can walk on water with a pat. The strength of surface tension is too weak to support body weight is greater.

Basilisk lizards, birds including Western Grebe water even some dolphins tail can walk on the surface with sufficient strength and speed to keep their bodies do not drown.

Basilisk lizard, for example, can run at speeds of more than five meters per second with a tap water with its hind legs. That pushed the water from his feet, and create a small air pocket around the foot. But lizards have to move his feet fast enough, so that the air bag did not close around the legs and dragged him into the water.

Small lizards can more easily generate the force needed to lift them out of the water. While the larger must square off on the ground to achieve the momentum required, to support the weight and still survive.

Most animals can only travel a short distance above the water. Some such as the basilisk lizard, do it to avoid predators on land. While others such as fishing spiders for food. And the others do so as part of an elaborate mating ritual, like the Western Grebe.

Electrical Energy Saving Tips at Home

The use of electrical appliances in the modern era is increasingly broad and diverse, including heavy industry to the household. Household electrical appliances in general are designed for efficient power consumption / saving, but in practice still found in a waste of electrical energy.  
This can occur because of the use of equipment in a manner that is less precise. The principles that need attention and cultivate the attitude of electrical energy saving in households, among others:  
  1. Connect the power of electricity as required. Households small example, with enough power 450 VA or 900 VA, households are enough to power 900 VA to 1300 VA.  
  2. Choosing the right equipment and household needs. 
  3. Shape the behavior of household members economize electric energy, such as:  
    • Turning power tools only when necessary.   
    • Using power tools in turn.  
    • Using electric power to supplement household income (productive).  
    Step-by-step use of household electrical appliances in saving electrical energy consumption: 
    1. Refrigerator / Freezers.  
    • Choosing a refrigerator with the size / capacity accordingly. 
    • Opening the refrigerator door as necessary, and in certain conditions can be maintained for closed meetings. 
    • Filling the refrigerator as necessary (do not exceed capacity).  
    • Placing the refrigerator away from heat sources such as sunlight, stove.  
    • Leaving the refrigerator at least 15 cm from the wall / walls of the house.  
    • Does not include food / beverage is still hot into the fridge.  
    • Clean the condenser (located behind the fridge) on a regular basis from dust and dirt, so that the heat release process went well. 
    • Set the refrigerator temperature as needed / not too low, because of the lower / cold more and more electrical energy consumption.  
    • Turning off the fridge when unused for long periods of time.  
    2. Electric irons  
    • Adjust the heat level required by the fabric to be ironed. 
    • Clean the bottom of the iron from the crust that can inhibit the heat.  
    • Turn off the iron immediately after ironing is completed or when will be left to work on another. 
    3. Television, Radio, Tape Recorder 
    Turning off the television, radio, tape recorder, and other audio visual equipment when not watching or not heard. 

    4. Water Pump.
    • Using a water tank and water pump turned on only when water in the tank is running low, or use automatic control system. 
    • It would be better when using the buoy automatic circuit breaker, which would cut off electrical current to pump water when the water is full. 
    • The more often pump water "living dead", the greater the power is used. 
    • Choosing the type of water pump in accordance with the requirements and that have a high level of efficiency. 

    5. Fan  
    • Opening vents / windows of the house to facilitate air into the house. 
    • Turning on the fan as needed and turn off when not necessary anymore. 
    • Choosing a fan that has a timer (timer) and set the timer as needed. 
    • Set the fan speed as necessary. 

    6. Air Conditioning (AC)
    • Choosing energy-efficient air conditioning and power according to the size of the room. 
    • Turn off the AC when the room is not used. 
    • Adjust the room temperature sufficiently, do not set the AC too cold. 
    • Closing the doors, windows and ventilate the room for hot air from the outside not inside. 
    • Placing AC as far as possible from direct sunlight for cooling effect is not reduced. 
    • Cleaning the strainer (filter) with regular air. 

    7. Washing Machine
    • Choosing a washing machine with a capacity in accordance with the amount of laundry every day. 
    • Using a washing machine in accordance with its capacity. When you exceed the capacity, to increase the load of electricity. When the laundry is a bit try to wash by hand only.  
    • Dryers should be used only during cloudy or rainy. When a sunny day in drying alone. 

    8. Rice Cooker 
    • Choose a rice cooker with a capacity in accordance with needs. 
    • Leaving the rice cooker in an upright position so that the electric breaker tool will work fine.  
    • Cook rice according to the capacity of a rice cooker. 
    • Try to cook the rice near the time of eating. 
    • Always check the automatic electric breakers. When the tool is damaged then the electricity will continue to flow into the heating element even though the rice is cooked.

    9. Dust vacuum (Vacuum Cleaner)  
    • Choosing a vacuum cleaner in accordance with needs and with sufficient power. 
    • Cleaning the dust bag immediately after use vacuum cleaner. 
    • Using a vacuum cleaner to work hard enough, if for light work / small just use a broom and other cleaning tools. 
    • Immediately turn off the vacuum cleaner when the motor gets hot or changes in the motor sounds, the possibility of something that interferes with work vacuum cleaner.  

    10. Lighting Lamp 
    • Using energy-saving lamps. 
    • Using electronic ballasts and installing capacitors on the type of fluorescent lamp / Neon. 
    • Turning on the lights only when necessary only, and turn off lights when not needed anymore. 
    • The color of the walls, floors and ceilings that light is very helpful in improving the efficiency of lighting. 
    • Install appropriate lighting / as close as possible to the illuminated objects. 
    • Adjust furniture so as not to obstruct light lamp. 
    • Clean the lamp glass when dirty / dusty so as not to block the light.

    How to Use Commercial Fertilizer


    If you're a home gardener wanting to increase your garden's yield, organic materials may not always be practical, so knowing how to use commercial (also known as synthetic or chemical) fertilizer correctly and with care may be your best option. Here is some help on how to use these powerful chemicals wisely. 

    Steps

    1. Understand what chemical fertilizers are made of. When buying a granular fertilizer, the bag should list the contents, including the percentage of three basic chemicals that are fundamental for plant growth. These three chemicals are represented by the label NPK on most fertilizer bags, and are, as follows:
      • Nitrogen. This is essential for leaf growth, and is used in higher proportion where a large plant and lots of foliage are desirable. Certain plants extract nitrogen from the atmosphere. One example is the leguminous plants, which include peas and beans. They have nodules on their roots that actually absorb nitrogen directly from the environment, and require little additional chemical nitrogen in their fertilizer. Corn, grains, and other crops that have narrow leaves, on the other hand, often require more nitrogen to thrive. It is represented by the N in the standard fertilizer label.
      • Phosphate. This is another chemical that plants require for good health. It is a product of phosphate mines or industrial waste, and plants use the chemical phosphorus in cellular processes. Phosphate is more common in soils containing a lot of clay, and is quickly leached from sandy loams or basic sandy soils. It is represented by the P in the standard fertilizer label.
      • Potash. This is the third chemical in the fertilizer description. It is also used by the plant at a cellular level, and is necessary for good bloom production and healthy fruiting of the plant. It is represented by the K in the standard fertilizer label.
    2. Research the nutrient requirements for the crop you are growing. Lawns and landscaping may benefit from a fertilizer blend with a larger proportion of nitrogen and moderate amounts of potash and phosphate, whereas garden plants are likely to benefit more from a specialized blend using less of one element, and more of another. If you are unsure of the exact needs of your plants, ask at your local garden supplier, or contact a government official specializing in agriculture, like the USDA or the County Extension Service in your area.
    3. Have your soil tested to understand what compounds are needed the most for your growing conditions and crops. Garden supply centers, farm suppliers, and county agriculture agents often can have soil samples taken and analyzed free of charge or at low cost. This type of analysis can be made for specific crops and used for calculating exact requirements for optimum fertilization. Failure to use an analysis means you will likely use too much or too little fertilizer.
    4. Calculate how much fertilizer you need. Application rates can be determined by measuring the area you plan to farm, then multiply the pounds per unit of area (X thousands of square foot, or acres) of the chemicals your soil analysis recommends, but if you choose to forgo this method, you can apply your fertilizer using your best judgment.
    5. Purchase the product you determine you need for your crop and soil condition. Fertilizer is sold in different sized bags, with larger bags usually costing less per pound (kilo), so you may find you will need to choose one that offers the best compromise for your purposes. A balanced fertilizer like 8-8-8 (10-10-10, or 13-13-13) may be the best choice for your garden. Also look at these other factors:
      • Secondary nutrients are needed in lower proportions than the basic three chemicals noted above, and help maintain the soil quality and contribute to healthy plants. The secondary nutrients include these:
        • Calcium
        • Sulfur
        • Magnesium.
      • Micro-nutrients. These are also essential for good plant health, and may or may not be included in your fertilizer choice. Look for the following, in particular:
        • Iron, in soluble form, helps with blooms, and to keep foliage green
        • Copper, in soluble form, also helps keep foliage green, and will improve resistance to some diseases
        • Zinc
        • Manganese.
    6. Decide if you want to combine other products with your fertilizer before purchasing. Special formulations of fertilizers that include herbicides and insecticides are available, and can be used to save application labor and time. Using these, however, limits you to areas where the chemical additives will not have an adverse effect. This includes fertilizers that contain pesticides that will contaminate plants, and herbicides that will damage the plants you are intending to grow. In general, using insecticides and herbicides on specific problems allows you to decrease the amount you need, and target problems with more effective results.
    7. Apply the fertilizer. There are a number of different methods for applying fertilizer, including direct application by hand, broadcast application, and using mechanical equipment to side dress the fertilizer to the growing bed. Which method used depends on the amount of fertilizer to be applied, the size of area it is to be applied on, and the size of the plants you are fertilizing.
      • Pre-plant application on a small area can be done by scattering fertilizer over the entire area and the tilling it into the soil. Apply at a rate of one or two pounds for each 100 square feet (9.29 square meters) maximum to avoid over-fertilizing the area.
      • Broadcast pre-plant application is suitable for larger areas, and a typical rate of application would be 200-400 lbs/acre (pounds per acre), using a calibratable fertilizer spread either pushed by hand, or pulled by a lawn tractor or farm tractor. After application, till the soil to incorporate the fertilizer and decrease the chance of run-off if rain occurs.
      • Direct application to individual plants or plants in rows can be done by pouring the fertilizer into a clean, dry bucket, then walking down the row dropping the fertilizer next to plants. Avoid dropping the fertilizer directly on plants, as the chemicals can burn them. Use a small amount, around one tablespoon each for small plants.
      • Direct application to row crops can be done with a cultivator equipped with a side-dressing apparatus. This apparatus consists of a hopper with a wheel to drive a dispensing mechanism and chutes to direct the fertilizer to the row.
    8. Cultivate or till the fertilizer into the soil around the plants to make it available to the plant's roots, to accelerate absorption, and to prevent run-off in case of rain. This can be done using a cultivator or tiller, or by simply using a hoe to stir the fertilizer into the soil.
    9. Watch for signs of over- or under-fertilization while your plants are growing. Overproduction of foliage without fruit production is one sign of over-fertilization, and weak, undersized plants usually indicates under-fertilization. Other factors, including disease, lack of water or sunlight, and insect damage may be mistaken for under-fertilization, so close observation and familiarity with the plants you are growing is essential for success.
    10. Repeat the application of fertilizer as needed to maintain good plant growth/ crop production. Using smaller amounts of fertilizer at frequent intervals may be more beneficial than applying single applications at a high rate, as some of the fertilizer can be lost by leaching or in run-off if heavy rains occur after it is applied.
    11. Clean up your application equipment as soon as you are finished using it. Chemicals in fertilizers are corrosive, and metal parts can be damaged if leftover material is not removed thoroughly.
      • Store your fertilizer spreaders or other tools in a dry place when not in use, and make sure they are well lubricated and maintained.
    12. Store unused fertilizer in its original package, if possible, in a dry, safe place. Opened bags should be taped or tied shut to prevent moisture from causing the fertilizer to clump, dissolve, or harden into a solid mass.

    Tips

    • Use fertilizer wisely. Allowing chemical fertilizers to run off is a source of pollution and a waste of money.
    • Do not fertilize before heavy rainfall is expected, as the fertilizer will likely be lost to run-off or leaching.
    • Buy only as much fertilizer as you need, as some chemicals break down with time, especially in contact with moisture, and become less effective.
