now
wiring to the bonsai
select a aluminum wire or copper wire
aluminum wire is very useful for bonsai making beginners
so
if you are new to making a bonsai
just select a thin aluminum wire
wiring is used to give a shape and style to the bonsai
and
wiring is a method of bending trunks and branches
when the plant is still young
the trunk is bent into the basic shape of a tree
Later
as the plant grows, you can bend the branches
when you are wiring the plant
do not over tight the trunk and branches
after wiring and shaping branches
then
choose a bonsai slap
make a potting wall using clay
after
potting the plant
put the layer of stones
now
removing old soil
don't hurt the roots when you are removing the soil
cut the long roots
place the tee in the slap
and
put the bonsai soil
removing air pockets
to remove the air pockets use a small stick
after planting
place the moss in top of the clay wall
moss will help to keep the soil moisture
and
give the beautiful look to the bonsai
after all
keep the tree in partial shade and sunny area

Symptoms of Kidney Cysts - Duration: 8:19.
Symptoms of Kidney Cysts
Surely, youve heard about kidney cysts more than once.
Thats because we are talking about a condition that is very common among our population, yet that is not usually considered to be extremely serious.
Nonetheless, its worth knowing more about where kidney cysts come from, as well as how they appear and what possible symptoms can come with them.
Well explain all this below so keep reading!.
What are simple kidney cysts?.
We all know the important function that our kidneys fulfil; they filter our blood, clean our body, control the salt in our body, and separate the waste substances that we discharge in our urine.
The kidneys are two essential organs for our overall health, which is why it is so important for us to know the possible illnesses associated with them.
But lets get to the point.
What is a kidney cyst? Well, a cyst is a sac or cavity full of air or liquid.
They normally consist of a membranous sac of abnormal character containing fluid.
They are lumps that emerge to the surface from the kidney itself or from the nephrons.
They are usually the size of a lentil, but in some cases there have been cysts the size of an apple.
They grow little by little, and inside them, there is usually harmless fluid rather than pus or blood.
Who commonly suffers from kidney cysts?.
First of all, we have to minimize the severeness of the matter.
Kidney cysts are not a synonym of cancer or of a complication that might take away our quality of life.
Simple kidney cysts are very common, especially when we start getting older.
They tend to appear when were in our 50s.
Although we can also get them before that age, after our 50s and 60s, they tend to appear with greater frequency.
Once again, we assure you they are usually harmless.
But why do kidney cysts appear?.
They normally start to appear as the years go by, due to the nephrons (the parts of the kidney that are in charge of filtering our blood).
They start getting bigger, and start to fill up with fluid.
Scientists dont know exactly why they happen, except that they happen over the years, like small injuries that cause the fluid to accumulate until it gets to a considerable size.
Also worth mentioning is the fact that kidney cysts are not hereditary.
If I have a kidney cyst, is it serious?.
Normally, the answer to that question is no. They are usually not serious.
Simple kidney cysts are associated with age and happen very frequently.
This is why they are called "simple kidney cysts", and they usually dont transform into cancerous tumors.
They are almost always harmless.
Now lets identify them and control them.
If their walls are thick and irregular, then they could be associated with a type of cancer.
But 70% of them are usually harmless and inoffensive.
What are the symptoms of a kidney cyst?.
Simple kidney cysts normally dont have symptoms.
This is why most people dont even realize they have a cyst or even 7 cysts in one kidney.
When they are discovered, it is by accident in X-rays or in a computerized axial tomography scan (CAT).
Another thing we should keep in mind is that if these fluid sacs explode, then we do have something to see a doctor about.
If you experience any of the following symptoms, see your doctor:.
Pain in the abdomen area, ribs, hips, stomach, or back.
Somewhat of a fever.
Urinating more often than usual and blood appearing in the urine.
High blood pressure.
How do you treat simple kidney cysts?.
Due to the fact that they are usually harmless, they are oftentimes not treated.
But if a cyst is forcing a lot of pressure on the kidney, it will end up hindering its function, so there will be no other option than to intervene.
And what does the intervention entail? It can be done two different ways, depending on where the cysts is located and how big it is:.
Suction or sclerotherapy: Through an injection, the cyst fluid is eliminated.
Surgery: Generally it is done through laparoscopy, using thin instruments that are inserted through small perforations in the abdomen.
During the surgery the doctor drains the cyst and then clips it off or cauterizes it.
It is done very quickly and the patient will only be in the hospital for a couple of days.
Can I prevent kidney cysts?.
They tend to appear with age, but a basic way of keeping your kidneys in good shape is maintaining a healthy lifestyle.
And you know how:.
Avoid smoking and drinking alcoholic beverages.
Drink two liters of water a day.
Avoid salts, refined flours, sugar, and carbonated beverages.
Eat fresh fruits and vegetables, avoid red meat.
Drink natural fruit juices.
Drink – for ten days a month – a cup of water with a teaspoon of baking powder after your dinner.

How to calculate density | Density formula, example, problem – Dr K - Duration: 8:29.
If you're looking to find out what density is all about, its formula and how
to solve density related problems, you've come to the right video .
Hi! Welcome to ChemSimplified. I'm Dr. K and
in this video we'll go through how to calculate density using 2 examples.
In one of the examples, we will also touch on measuring
volume through water displacement, so stick around until the end if you're in that.
First off, here's the formula for density. It's pretty straightforward actually.
It's mass divided by volume.
Normally, density of solid is expressed in grams per cm cube. While for liquid it's
grams per ml. These two units are actually the same numerically because
1 cm cube is actually equals to 1 ml. It's just that when you measure the volume of
solid it's calculated in units of length cube. Meaning like cm cube meter cube.
Whereas for liquid, it's usually measured in milliliter. So that's why there's a
difference in the unit for the density of solid and liquid. For density of gas
it's usually expressed in grams per liter. That's because gas is the less dense
than liquid so if the density of gas is also reported in grams per ml, the value
would be very very small which is not very convenient to write, so that's why
it's normally reported in grams over liter.
Okay so now that we know the formula, let's talk about density. What are some
of the examples of density that are being applied in our daily lives?
Well, the first that I can think of is iceberg. We see frozen freshwater floating in seawater.
Now, the frozen freshwater has lower density than seawater and that's
why it floats. Another one that will be familiar would be ice soda. We have ice
floating in our soda. The reason the ice floats is because the
ice has lower density than soda water. The third one which may not seem related
to density is vaccine or medicine. So what does density have to do with
needles and vaccine? Think about this. Whenever you get a jab for something, right?
A vaccine for hepatitis or a vaccine for tetanus,
I don't know just something have you ever seen the doctor or the nurse weigh out
the mass of the vaccine? No, right? It's always measured using a syringe, correct?
Well that's because it's easier to measure the volume of a liquid than to
measure the mass of a liquid, so that's why the vaccine is always measured using the syringe.
So how do we know how much volume to draw out? Well it can be easily
calculated when the density of the vaccine is known. In fact let's go ahead
and do an example. Let's assume that we need to administer 1.2g
of vaccine X. Knowing that vaccine X has a density of 0.785 g/ml
at twenty degrees Celsius. We can calculate the volume that we can
easily measure out using the syringe. So let's start with the formula for density,
which is mass over volume. But since we want to calculate volume, let's rewrite
the formula a little bit. We arrange it so I bring volume up so then it becomes
volume equals mass over density. Now let's plug in the values that we have we have.
1.2 g for the mass and 0.785 g/ml for the density and
dividing these two numbers will give us 1.5 and if we cross out the unit it will
leave us with ml so the volume is 1.5 ml so we can easily draw out the volume of
1.5 ml using syringe much easier than if we were to measure out 1.2 g.
Make sense? This is a really direct simple problem related to density.
Now, let's look at another density related problem that's a little bit more difficult.
So we have a task here, which is to figure out whether the crown is
made out of pure gold or not and we're given two masses. The mass of the crown
in the air, that's 4258 g and the mass of the crown in water
that's 3926 g and then we are also given 2 densities for our reference.
One is for a gold and the other one is density of water and we're
given the look of the crown so it looks like a gold crown and we're trying to
figure out whether that's pure gold or not. So to figure out whether is pure
gold or not we basically have to figure out the density of the crown and then we
compare it with the density of gold so if we figure out that the density of
crown is somewhere near, really close to 19.31 we can conclude
that the crown is made out of pure gold, right? So you might be wondering why are
there two masses given for the crown? What's the purpose of it?
Well, take a look at the crown will you be able to measure the Crown's volume? I mean it's
not a perfectly shaped cone or a rectangle, so we can't apply a formula to
come up with a volume. So what we're gonna have to do is we're gonna displace
water and measure its volume that way. So we're gonna use Archimedes principle to
figure out the volume of our crown so we start off by measuring the mass of the
crown in the air and that's 4258 g so what we do is then we
fill up a tank all the way up to the spout with water and then we submerge
the crown. So once we submerge the crown some water will be displaced out.
That means we can use the mass of the displaced water to calculate the volume
of the crown. This is sometimes referred to as volume by water displacement.
It's a popular method to figure out the density of all shape object, so let's see how
we're going to figure out the volume of our crown using this way.
We start off by subtracting the two masses that were given. That will help us
figure out the mass of the water displaced so the mass of the crown in
the air is 4258 minus the mass of the crown in water which is
3926 subtracting these two numbers will give us 332 g.
So that is the mass of the water that is displaced out. Now since we know
the mass of the water and the question gave us the density of water, we can
easily figure out the volume of the water that's displaced, so volume is
equals to mass over density. We just simply rewrite the formula of density so
plug in these numbers will give us 332 ml. Since the water that
is displaced out is due to the submerged crown, we can conclude by saying that the
volume of the crown is also the same as the volume of the water that is displaced out,
which is 332 cm cubed. Notice I just changed the unit ml to cm cubed
because I'm now talking about the crown. Crown is a solid object so I'm
using the appropriate unit for solid. So now that we have found the volume of our
crown and we know the mass of our crown, the one that's in the air. We can apply
the density formula and we can figure out what's the density of the crown.
So we take the mass which is 4258 g divided by 332 cm cubed,
and that will give us12.8 g/cm3. Now compare the
density of the crown that we just calculated with the density of gold.
Gold is 19.31. What do you think? Is the crown made out of pure gold?
Sadly, no. So looks like the crown is not made out of pure gold. So these are two
examples to show you how density can be used in real-life application.
Just to recap, density is mass divided by volume. Hope you find this video helpful.
