How to make a cloud in a  glass jar ?

Supplies:

                ►Large glass jar (one gallon size )

                ►Matches

                ►Rubber glove

                ►Rubber band

                ►Flashlight or a lamp

                ►Food coloring

                ►Water

How it work?

                   The air is full of warm water vapor molecules inside the jar. The air is compressed by the glove because the glove takes up some of the space inside the jar. Pulling the glove fingers out of the jar releases some space in the jar. The air inside the jar cools. The smoke from the match acts as a vehicle that the water molecules can attach to. They stick to the smoke particles, condensing into cloud droplets. When the glove fingers go back into the jar, the air inside the jar warms up again and the cloud disappears.

Step 1:      Pour boiling water into the jar.

               Cover to the bottom of the jar with water.

               Swirl the water around the jar.

               Use oven mitts if the jar is very hot.

Step 2:      Put the rubber glove wrist around the mouth of the jar.

               Having the fingers of the glove pointing downward into the jar will seal in the air into the jar.

Step 3:      Try to put you hand in the glove.

               With this you can make sure that noting happens to the water in the jar.

Step 4:      Light a match and drop it in the jar.

               Take off the glove from the jar for a moment.

               Light a match and drop it in to the jar.

               Stretch the glove back over the jar.

               The water at the bottom of the jar will put out the match, and smoke will from in te jar.

Step 5:      Light a match and drop it in the jar.

               Slide you hand into the glove and pull it outward agin.

               This time a cloud will form in the jar, and when you put you hand back inside the jar the cloud will disapper.

Step 6:      Have fun.

               If you use a flashlight on the jar you will be able to see the cloud better.

               If you add few drops of food coloring to the water in the botton of the jar, you can see the cloud bloom with differents colors.

               

Recycling

Recycling saves energy, reduce raw material extraction and combats climate change.

Other recycling facts:

• Every American makes about four (4) pounds of garbage daily.
• Every month Americans throw away enough glass bottles and jars to fill up a giant skyscraper (like the Empire State Building).
• Recycling one aluminum can saves enough energy to run a TV for three hours.
• Recycling one (1)-ton (approximately 2,000 pounds) of paper saves seventeen (17) trees, two (2) barrels of oil (enough to run the average car for 1,260 miles), 4,100 Kilowatts of energy (enough to power the average home for six (6) months) 3.2 Cubic-yards of landfill, and sixty (60) pounds of pollution.

Color classification of recycling

Blue – Paper

Green – Glass

Yellow – Metal

Red – Plastic

The recycling process

1.             Collection: In the first step of the recycling process, the recycling materials are collected.
2.       Processing: Once cleaned and sorted, the recyclables are processed to retrieve the raw materials, and the raw materials are then used in manufacturing recycled content products.
3.       Purchasing Recycled Products: The third step involves purchasing recycled products. This third step completes the recycling loop.

Exoskeleton

eLegs

The exoskeleton is a external skeleton that upports and protects the body. In nature we find diferents types of exoskeleton that are known as "shells", some examples are insects and crustaceans. The humans use that animal as idea to create the humans exoskeletons to help people with disabilities, the idea born as a military use, they think to use the exoskeleton to increase the soldiers capabilities, but people found a better use in medicine.

eLegs is a type of exoskeleton that support the legs of a pacient with disability, and help the paciento to walk. The suit consists of a backpack with a controller connected to a robotic legs . It is powered by four engines, two for the hip and one for each knee. The ankle joint is controlled by springs that keep the foot angled to walk . While the sensors in the legs send information to the control unit to determine how they should be bent joints. The team has lithium - cobalt batteries allow the suit to be operated with full autonomy .

How to test a LED bulb?

Before starting the  LED test we requieres a multimeter, thats is a1 special digital machine used to test the voltage of LED bulbs.

 First Step:   

                   Connecting the LED bulb to the multimeter.

            

The LED bulb has two terminals: the anode (positive) and the cathode (negative). Them you connect the black testing lead to the COM terminal on the multimeter and the red testing to the multimeter's terminal that ha the Omega sign. Be sure that black probe of the lead connect to the cathode and the red probe connects to the anode of the bulb. When you turn on the multimer display should show you "OL" or "OPEN".

Second Step:                     

                       Interpreting LED Test Results

If the multimeter display show you "OL" or "OPEN" you can be ure that connection is correctly, them you can start testing the LED bulb, first it is important to shield the bulb to see how it glows, if the bulb glows with a dim light the LED is with lower efficiency, but if the bulb glows with clarity and brightness the LED is with higher efficiency.

Explaining Procedures

To begin , we must know that the explanation of a procedure that is to follow is often of great importance to convey to others what you want to achieve .

To illustrate this, then it presents an example:

Discussing the details of a procedure (for example, endoscopy) with patients is often included in objective structured clinical examinations, and as a doctor you will always be required to inform patients sufficiently and involve them in decisions about any procedure they may require.

Introduce yourself appropriately to the patient, check if they have any prior knowledge of the procedure, if they have ever had the procedure before, or if they know someone who has. Then explain the purpose of the procedure, its approximate duration, and how they can expect to feel immediately afterwards.

Finally, answer any questions the patient might have, identify any concerns, and ensure all the information that you have provided is understood. Avoid using unexplained medical jargon.

Warnings

What is a Danger?
It is called danger, all the circumstances that may occur at any time where there may be a risk to the physical integrity of persons , animals or things that may be located in a particular area , either on a public road and a workplace or within any dwelling or commercial establishment .
There are many signs and classifications for different types of hazards. These signals can be classified as follows :

1. Warning Signs: Warn of danger. They are triangular in shape , with black pictogram on a yellow background (yellow must cover at least 50 % of the surface of the signal) and black edges ; only when the signal refers to harmful or irritating materials have the orange background to avoid confusion with similar signals used for road traffic regulation .
   
   

   

   Example

2. Danger Signals or Prohibition: Prohibit conduct liable to cause a hazard. black pictogram on white background, edges and band ( cross descending from left to right across the pictogram at 45 ° to the horizontal) red ( red shall cover at least 35 % of the area of ​​the sign ) .
   

   

   Example

3. Signals Obligation: Require a certain behavior. They are also round, but with white pictogram on a blue background ( the blue must cover at least 50 % of the area of ​​the sign ) .
   

   

   Example

4. Fire Signals: Indicate the site of a fire equipment or system . They have rectangular or square shape . The pictogram is white on a red background ( the red must cover at least 50 % of the area of ​​the sign ) . The elements and equipment used for fire fighting , will be housed in cabinets and painted red receptacles , which can easily identify equipment containing inside.
   
   
   

   

   Example

5. Distress signals or savingly: Rectangular or square shape , white pictogram on green background ( the green must cover at least 50 % of the area of ​​the sign ) . They are used to signal all escape exits the enclosure , plant or building with the direction of the paths to follow to the point where the outlet or relief system . signs will be used : "OUT " to indicate a way out of common usage, " EMERGENCY EXIT " to indicate which is provided for use in this situation "and" FIRE LADDER "to indicate a staircase arranged externally . In marked paths , any door that would mislead the evacuation will be signaled marked " No Exit " (white on red background security ) .

   

   Example

6. Signs Transport of Dangerous Goods: For proper identification , the vehicles transporting these kinds of goods, lead panels and reflective orange color, and a danger labels of different colors. The danger labels are diamond-shaped and background color and representative drawings indicate the danger of the transported product.

Comparing benefits: Human vs Machines

 

Nowadays there are machines everywhere, but why each day the amount of machines increases? Are the machines better than the humans? We will compare some benefits.

About the efficiency and speed

Machines can do many things more efficiently and more cheaply. For example, in the math areas the computers are faster than the humans but they can’t give solution to some problems because the common sense is necessary, something that the machines don’t have. There are some algorithms that allow to the computers search the answers to a specific problem but the humans do the job more efficiently, after of all, the machines are programed by the humans.

Multitasking

The multitasking work is something that the people love of the machines. Imagine a smart home, it is checking the temperature and meanwhile it is keeping the security around the house too, but isn’t just that, also it's attending your orders and queries using internet. In other hand the humans can do some things together but less than the machines, this is another point in favor of the machines.

Dependency and costs

The machines don't need sleep or eat and always are available (That doesn't apply to my printer and phone), that makes of them more productive and cheapest than the humans.

Social relations

Here still there’s nothing to discuss, the machines can not feel emotions or another human’s characteristics and therefore there are many things that a machine never can do, between these, make music,imagine, invent, and mainly think by itself.

Writing emails

How to write an email?

Firstly, you should think about what kind of person is directed the email that you will send. He’s your friend? He’s your boss? think about it… It’s so important to change your habitual writing form (informal) if you are sending emails to important or unknown people because it can talk many things about you. So for this reason, you always must try to write well. I'll explain it around the post.

Write a clear subject in the subject line which explains the reason for the message.

Sometimes the people don’t have time to read email by email, for this reason they only read the subject line, so, we must be considerate and write a good description about the email, for example write things like “It’s an emergency about our job” that describe the main idea in the email and don’t write things like “Hello” because the message could be important but the subject line represents totally the opposite.

Write short and concise sentences, use simple grammar.

I will retake the last point, sometimes the people don’t have time, so you must try to be concise in the sentences…. be clear and precise, the enough to explain what’s happening. Write the most important information first. It’s important to mention that in an email it is not necessary to use complex grammar to express the main idea even if it’s a formal situation, remember that the readers want “to-the-point messages”, but keep in your mind that you must never use regionalisms or words that not all the people can understand.

Something that you must not forget.

Never under any circumstances use capital letters to write words because it is considered a shouting in an email language. In a formal email you must not use emoticons... Avoid the abbreviations except if these are used in the professional environment.

If you email have more than one aim, you could sort it with numbers for each one to ease the reading to the receiver. Don’t forget write something to end the email, whatever you want but remember the kind of formality. For example, to write “Thanks for your attention”, or “Goodbye” in a friendly space.

There are more things that I can write about it but for ending the post remember “It is not necessary to use complex vocabulary to be formal”.
