Don’t Remove Baby’s Body Hair

A new born baby may have fine and soft hair in its body. This hair is called lanugo.

Many newborn babies have a lot of body hair. Body hair on newborns is not a cause for concern, and it usually goes away a few months after birth. Nature will take its course to let the hair shed by itself.

Lanugo is believed to help keep the baby warm. At an early gestation (The period of time that a baby develops inside its mother's body; the process of developing inside the mother's body) babies do not have a lot of fat stores and the lanugo may help maintain an appropriate body temperature.

You might hear that rubbing a ball of wheat dough (atta loi) over your baby's body will help to remove body hair and prevent it from being hairy later in life.

Rubbing atta will not permanently remove hair. They will grow again. Rashes may form on the baby’s skin.

Also, there are many home remedies to remove body hair of babies. These home remedies use milk, turmeric, flour, and other common household ingredients that have no harmful chemicals. There is no scientific evidence to suggest that they work effectively in removing body hair, but they have been used for a long time by our elders, and are a part of traditional remedies used by mothers.

These methods may not permanently remove the hair from your baby, so you may notice the hair growing back after some time.

You don't have to do anything special to treat the lanugo on your baby.

Time is the best treatment for newborn lanugo. Leave your baby’s hair alone and it will eventually disappear. In a few days or weeks, your newborn should lose lanugo. If it lasts longer, that can still be normal.

Do not wax, shave, or use a body hair remover to get rid of your baby's lanugo. These products are not safe for infants and could harm their delicate skin.

Massaging the area of skin very gently with mild baby oil might help expedite lanugo falling out, but use extreme care to prevent damaging your baby’s skin. Only use products that will not irritate your baby’s skin or eyes.

Gently massaging a baby’s skin after birth can facilitate the removal of lanugo. But this is not necessary. Massaging can be effective. But it is risky. A baby’s skin is delicate. If you inadvertently rub your baby’s skin too hard or too much, this can cause soreness, redness, or dryness. Therefore, it may be more beneficial to leave the hair alone and allow it to shed on its own.

Many full-term babies lose all their lanugo before they are born, but some do not. Whether your baby’s lanugo falls out before or after they're born, it will eventually go away. When it does, another type of hair will grow in its place. The new hair is called vellus hair.

Vellus hair is similar to lanugo but thinner and not as noticeable. This hair will cover your baby’s body throughout childhood. (Vellus hair is the light, short, fine hair that covers much of a person's body. Its length and thickness will vary from person to person. The primary role of vellus hair is to protect the skin and keep the body warm.)

What is Buoyancy?

This video explains the concept of Buoyancy.

From: https://www.youtube.com/watch?v=khc2wUBsFU4

What is Buoyancy?

Buoyancy is an upward force exerted by a fluid on an immersed object in a gravity field.

In fluids, pressure increases with depth; hence, when an object is immersed in a fluid, the pressure exerted on its bottom surface is higher than the pressure exerted on its top surface.

This difference in the pressure leads to a net upward force (buoyancy force) which opposes the gravity force and is equivalent to the weight of the fluid that would otherwise occupy the volume of the object, i.e. the displaced fluid.

Thus, if the object is less dense than the fluid, the buoyancy force will be higher than its weight and the object will float; on the contrary, if the object is denser than the fluid, it will sink.

The static balance occurs when the weight of the immersed part of the object is the same as the weight of the displaced fluid, i.e. the densities coincide.

Remark that the density of the object is meant in an averaged way, as a simple ratio between mass and volume of the immersed part.

The most common case is the immersion of a solid into a liquid (e.g. ships in the sea), but that’s not all: a rising bubble (gas in liquid), a falling droplet (liquid in gas) and aerostats (warm air into cold air) are examples of phenomena ruled by buoyancy forces as well.

Surface Tension - Why are drops spherical?

Topic: Surface Tension

Why are drops spherical?

Because personally, I am fond of spherical shapes as compared to squares.

No.

It is because of surface tension.

Surface tension is the property of liquids by which surface molecules of a liquid try to hold the liquid together by acquiring minimum surface area and acting like a stretched membrane.

You know what, everything just went over my head.

Alright. I will explain.

Inside a drop, each water molecule is pulled with a force by its neighboring molecules.

As these forces are equal and opposite, they get neutralized.

However, the molecule present at the surface is not attracted outwards.

It is attracted only inwards and sideways.

Sideways forces get neutralized.

But because of the inward force, each surface molecule contracts to form a shape that has minimum surface area which is a sphere.

Fibonacci Sequence in Nature

Fibonacci Sequence

Individuality -- the trademark of any artist, designer, or architect, each desires a uniqueness to their creation, a quality that separates it from any other.  Man naturally has this individuality.–his fingerprint. There are 6.5 billion people on the face of the earth and no two fingerprints are the same.  Everything we touch or make contact with is branded with a small expressed image revealing to all who see it - Who was there! 

Around 1200 AD  a man named Leonard Pisano, better known as Fibonacci, discovered a sequence of numbers that created a very interesting pattern.  The sequence begins with the numbers 1, 1, 2, 3, 5, 8, 13, 21, 34, and continues indefinitely.  Each number is obtained by adding the last two digits together.  A rectangle with the length and width of any two of the numbers of this sequence forms what is known as the golden rectangle, a perfect rectangle.  A golden rectangle can be broken down into squares the size of the next F numbers down and below.  If we were to take a golden or perfect rectangle, break it down into smaller squares based on Fibonacci’s sequence, and divide each with an arc, the patterns begins to take shape.   We begin to see Fibonacci’s spiral…the spiral in and of itself is insignificant; its importance is revealed in where we find it.

Take for example the sunflower the display of its florets are in perfect spirals of 55, 34 and 21 -  sequence of  Fibonacci; the fruitlets of the pineapple creates the same sequence;  the pine cone does the same.  As currents move through the ocean and the tide rolls onto the shore,   the waves that bring in the tide, curve into a spiral that can be mathematically diagrammed onto a plot:  1, 1, 2,3,5,8,13,21,34 and 55.

Buds on trees, sand dollars, starfish, petals on flowers and especially the nautilus shell are formed with this exact same blueprint.  With each segment of growth, the nautilus adds to itself one more value on Fibonacci’s scale.  This blue print can be seen around us on a small scale every day.  But the greatest example of all is directly above our heads.  At an average of 100, 000 light years across, even the spiral of the galaxies above us are formed with the exact design that the tiny shell is formed. This sequence, our blueprint, appears to be the trademark of a Designer, a proof of a Creator, something left behind Indicating the One who is there – a fingerprint.   As we span our universe from the tiny flower to the awe inspiring galaxies, we see the fingerprint of God.  And we are forced to ask:  “Who is God?”

Advanced Search Operators with Google

Andreas describes and demos some of the advanced search operators that Google uses to find exactly the data you want! (Most of these will work in any browser / search engine, by the way!)
From: https://www.youtube.com/watch?time_continue=35&v=fAQwWwZ8fs4&feature=emb_logo

A search operator or a search parameter is a character or string of characters used in a search engine query to narrow the focus of the search. ‘Search Operators’ are specific commands we can use in search engines to refine search results. Search operators are powerful and can save searchers a lot of time, especially since most operators can be used together.

Operator	Description	Example
site:	Get results from certain sites or domains.	olympics site:nbc.com and olympics site:.gov
link:	Find pages that link to a certain page.	link:youtube.com
related:	Find sites that are similar to a web address you already know.	related:time.com
-	When you use a dash before a word or site, it excludes sites with that info from your results. This is useful for words with multiple meanings, like Jaguar the car brand and jaguar the animal.	jaguar speed -car or pandas -site:wikipedia.org
"	When you put a word or phrase in quotes, the results will only include pages with the same words in the same order as the ones inside the quotes. Only use this if you’re looking for an exact word or phrase, otherwise you’ll exclude many helpful results by mistake.	"imagine all the people"

8 Car Secrets Only Experienced Drivers Know

Are you one of those drivers who trust their car mechanic fully? Good for you if you’ve found a true professional who takes good care of your vehicle! Unfortunately, not all mechanics are responsible and honest with their customers. There are several things they don't want you to know so that they can take advantage of you when you bring your car in.

SUMMARY:
- The truth is that the biggest problem with the battery comes not from the battery itself but from the wires connected to it. The spots where they're attached to the battery get damaged by corrosion.

- Various car experts state that the earliest you should start to worry about an oil change is after driving a minimum of 7,500 miles.

- You'll probably agree that no one can ignore the terrible screeching of car brakes. But the most likely cause of these terrible sounds is rust on the brake pads.

- Some car service centers attract clients by promising free bumper-to-bumper examinations of their vehicles. After you bring your car in, a mechanic will most likely discover that it has tons of problems — which need to be fixed right away.

- Don't fall for the offer of free lifetime muffler replacement! If you agree to this, you'll just end up paying more money in the long run.

-  Before you drive to the garage, mark the tires with chalk. You can write the letters "RL" on the rear left tire and "FR" on the front right tire. After you get your car back, check where the marks are.

- Few people know that the most widespread reason for the check engine light to appear on your dashboard is because your gas cap isn't fastened well enough.

- Your mechanic may suggest that you buy additives for the engine, gas tank, or transmission. After you agree, you find out that these additives cost you an arm and a leg!

How to Kill a Tree

5 Best Ways for How to Kill a Tree

 #1 Hack and Squirt

#2 Tree Girdling

#3 Roundup

#4 Salt

#5 Spraying Leaves

Chemicals to Use:

The main chemicals used for killing trees are Epson Salt, Hi-Yield Kill-Zall and Roundup which have the same active ingredient, and Fertilome Brush & Stump Killer which is used for killing trees by spraying the leaves.

#1 Hack and Squirt:

This is a super fast way to kill smaller trees. You simply use a hatchet to cut into the bark and spray with 50/50 roundup concentrate. This is a good method if you have a lot of small trees you need to thin out of a forest. It's not very practical if you live in the city unless you don’t mind a dying tree in your yard for several months.

#2 Tree Girdling:

You could be old school and use an antique hand saw or just use a generator and reciprocating saw. Cut a 1” slice out of the bark and first layer of the tree all the way around. Then chop it out with a hatchet. This will cut off the water supply to the tree and it will die. I would only use this method if you live in the boonies are wanting to harvest the tree later for firewood once it is dead and dry.

#3 How to Kill a Tree with Roundup:

This is the best way to kill a tree in your yard. Cut your tree down with a chainsaw. I love my 460 Rancher. In the lighter outer ring of the tree drill holes and then fill the holes with 50/50 Roundup. Killing the tree like this will kill the tree stump and all the roots completely. Just cutting down most trees isn’t enough for them to die. This will avert any shoots coming up from the stump or roots.

#4 How to Kill Tree with Salt:

This works well especially if you don’t like using chemicals. It works much the same as using roundup. First, cut the tree down and then drill holes all the way around in the lighter outer ring of the tree. Fill the holes with Epsom salt. This should kill the tree. This is also a good way to remove tree stumps.

#5 Kill Tree by Spraying Leaves:

 I always have a bunch of little trees popping up in my yard like weeds. Using Fertilome Brush & Stump Killer works well these. Mix 4 to 8 ounces into 1 gallon of water. Screw the top on and pump and Shake to mix well. Spray the leaves thoroughly. You can see that I have a bunch of trees that I can quickly kill this way.

Dengue and Chikungunya

Dengue and Chikungunya 

Dengue

Overview

Dengue (DENG-gey) fever is a mosquito-borne disease that occurs in tropical and subtropical areas of the world. Mild dengue fever causes a high fever, rash, and muscle and joint pain. A severe form of dengue fever, also called dengue hemorrhagic fever, can cause severe bleeding, a sudden drop in blood pressure (shock) and death.

Millions of cases of dengue infection occur worldwide each year. Dengue fever is most common in Southeast Asia and the western Pacific islands, but the disease has been increasing rapidly in Latin America and the Caribbean.

Researchers are working on dengue fever vaccines. For now the best prevention is to reduce mosquito habitat in areas where dengue fever is common.

Symptoms

Many people, especially children and teens, may experience no signs or symptoms during a mild case of dengue fever. When symptoms do occur, they usually begin four to seven days after you are bitten by an infected mosquito.

Dengue fever causes a high fever — 104 F degrees — and at least two of the following symptoms:

·         Headache

·         Muscle, bone and joint pain

·         Nausea

·         Vomiting

·         Pain behind the eyes

·         Swollen glands

·         Rash

Most people recover within a week or so. In some cases, symptoms worsen and can become life-threatening. Blood vessels often become damaged and leaky. And the number of clot-forming cells (platelets) in your bloodstream drops. This can cause a severe form of dengue fever, called dengue hemorrhagic fever, severe dengue or dengue shock syndrome.

Signs and symptoms of dengue hemorrhagic fever or severe dengue — a life-threatening emergency — include:

·         Severe abdominal pain

·         Persistent vomiting

·         Bleeding from your gums or nose

·         Blood in your urine, stools or vomit

·         Bleeding under the skin, which might look like bruising

·         Difficult or rapid breathing

·         Cold or clammy skin (shock)

·         Fatigue

·         Irritability or restlessness

When to see a doctor

Call or go to the nearest emergency room if you've recently visited a region in which dengue fever is known to occur and you develop emergency symptoms, such as severe abdominal pain, vomiting, difficulty breathing, or blood in your nose, gums, vomit or stools.

If you develop a fever and milder symptoms common to dengue fever, call your doctor.

Causes

Dengue fever is caused by any one of four types of dengue viruses spread by mosquitoes that thrive in and near human lodgings. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. When the infected mosquito then bites another person, the virus enters that person's bloodstream.

After you've recovered from dengue fever, you have immunity to the type of virus that infected you — but not to the other three dengue fever virus types. The risk of developing severe dengue fever, also known as dengue hemorrhagic fever, actually increases if you're infected a second, third or fourth time.

Risk factors

Factors that put you at greater risk of developing dengue fever or a more severe form of the disease include:

·         Living or traveling in tropical areas. Being in tropical and subtropical areas increases your risk of exposure to the virus that causes dengue fever. Especially high-risk areas are Southeast Asia, the western Pacific islands, Latin America and the Caribbean.

·         Prior infection with a dengue fever virus. Previous infection with a dengue fever virus increases your risk of having severe symptoms if you're infected again.

Complications

If severe, dengue fever can damage the lungs, liver or heart. Blood pressure can drop to dangerous levels, causing shock and, in some cases, death.

Prevention

One dengue fever vaccine, Dengvaxia, is currently approved for use in those ages 9 to 45 who live in areas with a high incidence of dengue fever. The vaccine is given in three doses over the course of 12 months. Dengvaxia prevents dengue infections slightly more than half the time.

The vaccine is approved only for older children because younger vaccinated children appear to be at increased risk of severe dengue fever and hospitalization two years after receiving the vaccine.

The World Health Organization stresses that the vaccine is not an effective tool, on its own, to reduce dengue fever in areas where the illness is common. Controlling the mosquito population and human exposure is still the most critical part of prevention efforts.

So for now, if you're living or traveling in an area where dengue fever is known to be, the best way to avoid dengue fever is to avoid being bitten by mosquitoes that carry the disease.

If you are living or traveling in tropical areas where dengue fever is common, these tips may help reduce your risk of mosquito bites:

·         Stay in air-conditioned or well-screened housing. The mosquitoes that carry the dengue viruses are most active from dawn to dusk, but they can also bite at night.

·         Wear protective clothing. When you go into mosquito-infested areas, wear a long-sleeved shirt, long pants, socks and shoes.

·         Use mosquito repellent. Permethrin can be applied to your clothing, shoes, camping gear and bed netting. You can also buy clothing made with permethrin already in it. For your skin, use a repellent containing at least a 10 percent concentration of DEET.

·         Reduce mosquito habitat. The mosquitoes that carry the dengue virus typically live in and around houses, breeding in standing water that can collect in such things as used automobile tires. You can help lower mosquito populations by eliminating habitats where they lay their eggs. At least once a week, empty and clean containers that hold standing water, such as planting containers, animal dishes and flower vases. Keep standing water containers covered between cleanings.

Chikungunya 

What is Chikungunya?

Chikungunya is a mosquito-borne viral disease, very similar to dengue. The mosquitoes which spread it are Aedes aegypti and Aedes albopictus. These mosquitoes acquire the virus when they feed on an infected person. The virus spreads in the system of the mosquito and reaches its salivary glands. Soon after, when the mosquito feeds on a person, it infects him.

The infection lasts for 2 to 12 days.

If you notice any of the following symptoms, you need to consult your family physician or a general physician immediately:

• ·         Continuous high fever (above 38.5 degree Celsius)
• ·         Debilitating joint pain and redness or soreness in the joint areas
• ·         Rashes on the skin
• ·         Nausea
• ·         Vomiting
• ·         Sensitivity to light
• ·         Headache

How does Chikungunya occur?

Once the Aedes mosquito bites a person suffering from Chikungunya, the Chikungunya virus enters the mosquito’s system. After getting infected when the mosquito feeds on another person, the virus gets transmitted to the person.

The virus travels through his body and spreads to various glands in the body. It enters the bloodstream and causes inflammation of the blood vessels, causing them to swell and leak.The Chikungunya virus usually targets joints, muscles, skin, and less frequently, the liver, kidneys, eyes and the central nervous system.The Chikungunya virus mainly infects the muscle cells of the body. Once it infects a muscle cell, it keeps reproducing till the cell dies and then the viruses move onto a new cell.If you contract this disease you may experience severe muscle pains, joint pains, fever and rash.

What are the symptoms of Chikungunya? How is Chikungunya diagnosed?

The symptoms of Chikungunya include:

• ·         High fever
• ·         Severe muscle and joint pain
• ·         Severe headache
• ·         Nausea
• ·         Vomiting
• ·         Rash on the skin due to damaged blood vessels
• ·         Enlarged painful lymph node in the neck
• ·         Sore throat
• ·         Painful abdominal cramps
• ·         Cold fingers and toes
• ·         Dizziness
• ·         Constipation

Chikungunya symptoms can often be confused with the symptoms of dengue. However, certain symptoms such as debilitating joint pains are unique only to Chikungunya. In fact, it is said dengue plus arthritis is equal to Chikungunya.

In dengue, the muscle pain is very noticeable.

Diagnosis

A special blood test known as ELISA blood test (enzyme-linked immunosorbent assay) is done to confirm the presence of Chikungunya virus in a patient. During the test, if IgM antibodies are found (which can last up to one year in the blood) it confirms the presence of Chikungunya virus in the body.

These antibodies reveal the presence of the Chikungunya virus.

What are the complications of Chikungunya?

Some complications of Chikungunya include:

• ·         Neurological imbalances
• ·         Seizures
• ·         Myocarditis or inflammation of the heart muscle
• ·         Ocular disease or eye disease (uveitis, retinitis)
• ·         Jaundice caused by liver damage
• ·         Acute renal disease when kidneys get affected
• ·         Severe bullous lesions 
• ·         Neurological diseases, such as meningoencephalitis, Guillain-Barré syndrome, myelitis, or cranial nerve palsies

What is the treatment for Chikungunya?

Chikungunya is a self-remitting illness. There is no particular medication or treatment available for chikungunya.

The doctor may advise you to take plenty of rest, fluids, and provide you painkillers. Even while prescribing pain-killers, paracetamol is recommended for treating the pain and fever. Nonsteroidal anti-inflammatory drugs are never prescribed.

The usual treatment for the severe form of Chikungunya consists of:

·         Providing Intravenous (IV) fluid and electrolyte replacement

·         Monitoring blood pressure

·         Blood transfusion to replace blood loss, if any
