Many people have the wrong idea about what repentance means Repentance does not mean that you admit that you are a sinner Repentance means that you are not the boss any more and you don’t do what pleases you any more which includes SIN It means that you have accepted Jesus Christ as your Lord you are UNDER NEW MANAGEMENT!
the management of the Kingdom of Heaven Jesus Christ has become your boss You have accepted Him as the Alpha and Omega, the beginning and the end in your You OBEY Him you DO WHAT HE TELLS YOU TO DO You don’t sin, no more you don’t do your own plans, no more You are following Jesus you GO where He tells you and you DO what He tells you because you are UNDER NEW MANAGEMENT You are under management of the Kingdom of Heaven you DO what pleases God because Jesus Christ is your LORD and God is your Father That is what repentance means may Jesus Bless you �

Very fun to draw with iPad Ja Jan!
Smart Pen The pen point is soft like cloth.
smoothly on the screen But hard to touch on narrow point.
I think thinner pen point will be better.
to prevent the sebum of fingers attaching to the screen smoothly more smooth than silicon stylus pen point can use it for memo, drawing and making a animation etc..
enough to rough drawing (not for exact drawing) Of course, for a usual operation.
possible to use iPhone or iPod touch good for trying the “Smart Pen”

Hi, my name is Laura Bodine, and I’m a graduate student at Eastern Illinois University in the dietetics program.
Today, I’m going to talk to you about chronic kidney disease, explain how to manage the disease with nutrition, and at the end I’m going to show you how to make a simple and delicious baked apple dessert.
is a gradual and progressive disease that causes damage to the kidneys.
The kidneys are the main organ in the body that are important for removing excess waste as well as maintaining fluid and electrolyte balance and producing hormones that are important for the body to function properly.
When damage occurs to the kidneys, they can no longer perform these functions and you may start to feel symptoms like nausea, vomitting, fatigue, and headaches.
People at the highest risk for developing chronic disease are those with diabetes, hypertension, and heart disease.
Once someone already has the disease, nutrition is not only important for overall good health but may even help slow the progression of the disease and damage to the kidneys.
The main goals for using nutrition as therapy are to decrease the excess amounts of fluid and waste that build up in the body.
There are a few basic rules to follow when trying to do this.
First, getting enough total calories in the diet is important to prevent your body from breaking down its own tissues for .
It’s especially important to get the right amount of protein in the diet.
In the early stages, this usually means decreasing the amount of protein you’re getting.
So its important to get protein from high biological value foods like eggs, chicken, and fish because these are going to help your body maintain and repair body tissues.
Second, it’s also important to limit the amount of sodium in your diet.
Sodium is responsible for fluid balance and when there’s too much, the body is going to hold onto extra fluid and can increase your blood pressure.
By decreasing the amount of sodium you add during the cooking process and also by avoiding foods high in salt like canned soups, bacon and ham, or going to fast-food restaurants for meals is an easy way to decrease the amount of sodium in your diet.
Potassium is another nutrient that needs to be decreased in the diet as well.
When potassium gets too high, the kidneys have a hard time removing the excess amounts.
So avoiding foods high in potassium like fruits and vegetables, specifically bananas, potatoes, oranges, and tomatoes need to be limited in the diet.
It’s also important to watch out for salt substitutes because these can contain high amounts of potassium as well.
So adding different spices in the cooking process can help increase and maintain flavor of foods.
Lastly, phosphorous needs to be restricted in the diet as well to help protect your bones.
When there’s too much phosphorus in the diet, this can actually decrease the amount of calcium you’re getting and lead to bone disease later on.
So by avoiding foods high in phosphorus like whole grains, nuts and seeds, and milk products is especially important for people with chronic kidney disease.
It may also be necessary to add a calcium supplement for people with this disease in order to help protect your bones.
Keep in mind that each person is different and that this is a progressive disease.
So talk to a registered dietitian to find out what your personal and individualized diet would look like.
Now, I’m going to show you how to make a simple and delicious baked apple dessert.
First, you’re going to start out with a medium-sized apple and you’re going to wash and core the apple so that it looks like this and add it into a bowl that has high sides, which is important for the cooking process.
From here, you add 2 teaspoons of honey and pour that right into the center of the core of the apple.
Then from there, you would add 1/8 teaspoon of nutmeg and sprinkle that over the top of the apple.
Then lastly, you add 1/4 teaspoon of cinnamon and sprinkle that over the apple as well.
This is what it should look like when you’re done with this process.
From here you can either bake it at 350 degrees for 20 to 30 minutes or if you can’t wait that long, you can cover it with Saran Wrap and microwave it on high for 6 minutes.
When it comes out of the microwave, by adding 1/4 cup of Cool Whip, you’re going to get this as your final dessert.
This one apple will equal one serving.
Apples are great because they’re not only low in potassium, but they’re a great sweet treat for you.

Two circles useful for deriving the centripeta...

Welcome back.
I’m now going to introduce you to the concepts of work and energy.
And these are two words that are– I’m sure you use in your everyday already and you have some notion of what they mean.
But maybe just not in the physics context, although they’re not completely unrelated.
So work, you know what work is.
Work is when you do something.
You go to work, you make a living.
In physics, work is– and I’m going to use a lot of words and they actually end up being kind of circular in their definitions.
But I think when we start doing the math, you’ll start to get at least a slightly more intuitive notion of what they all are.
So work is energy transferred by a force.
So I’ll write that down, energy transferred– and I got this from Wikipedia because I wanted a good, I guess, relatively intuitive definition.
Energy transferred by a force.
And that makes reasonable sense to me.
But then you’re wondering, well, I know what a force is, you know, force is mass times acceleration.
But what is energy?
And then I looked up energy on Wikipedia and I found this, well, entertaining.
But it also I think tells you something that these are just concepts that we use to, I guess, work with what we perceive as motion and force and work and all of these types of things.
But they really aren’t independent notions.
They’re related.
So Wikipedia defines energy as the ability to do work.
So they kind of use each other to define each other.
Ability to do work.
Which is frankly, as good of a definition as I could find.
And so, with just the words, these kind of don’t give you much information.
So what I’m going to do is move onto the equations, and this’ll give you a more quantitative feel of what these words mean.
So the definition of work in mechanics, work is equal to force times distance.
So let’s say that I have a block and– let me do it in a different color just because this yellow might be getting tedious.
And I apply a force of– let’s say I apply a force of 10 Newtons.
And I move that block by applying a force of 10 Newtons.
I move that block, let’s say I move it– I don’t know– 7 meters.
So the work that I applied to that block, or the energy that I’ve transferred to that block, the work is equal to the force, which is 10 Newtons, times the distance, times 7 meters.
And that would equal 70– 10 times 7– Newton meters.
So Newton meters is one, I guess, way of describing work.
And this is also defined as one joule.
And I’ll do another presentation on all of the things that soon.
Joule did.
But joule is the unit of work and it’s also the unit of energy.
And they’re kind of transferrable.
Because if you look at the definitions that Wikipedia gave , work is energy transferred by a force and energy is the ability to work.
So I’ll leave this relatively circular definition alone now.
But we’ll use this definition, which I think helps us a little bit more to understand the types of work we can do.
And then, what kind of energy we actually are transferring to an object when we do that of work.
So let me do some examples.
Let’s say I have a block.
I have a block of mass m.
I have a block of mass m and it starts at rest.
And then I apply force.
Let’s say I apply a force, , for a distance of, I think, you can guess what the distance I’m going to apply it is, for a distance of d.
So I’m pushing on this block with a force of F for a distance of d.
And what I want to figure out is– well, we know what the work is.
I mean, by definition, work is equal to this force times this distance that I’m applying the block– that I’m pushing the block.
But what is the velocity going to be of this block over here?
Right?
It’s going to be something somewhat faster.
Because force isn’t– and I’m assuming that this is frictionless on here.
So force isn’t just moving the block with a constant velocity, force is equal to mass times acceleration.
So I’m actually going to be accelerating the block.
So even though it’s stationary here, by the we get to this point over here, that block is going to have some velocity.
We don’t know what it is because we’re using all variables, we’re not using numbers.
But let’s figure out what it is in terms of v.
So if you remember your kinematics equations, and if you don’t, you might want to go back.
Or if you’ve never seen the videos, there’s a whole set of videos on projectile motion and kinematics.
But we figured out that when we’re accelerating an object over a distance, that the final velocity– let me change just for variety– the final velocity squared is equal to the initial velocity squared plus 2 times the acceleration times the distance.
And we proved this back then, so I won’t redo it now.
But in this situation, what’s the initial velocity?
Well the initial velocity was 0.
Right?
So the equation becomes vf squared is equal to 2 times the acceleration times the distance.
And then, we could rewrite the acceleration in terms of, what?
The force and the mass, right?
So what is the acceleration?
Well F equals ma.
Or, acceleration is equal to force divided by you mass.
So we get vf squared is equal to 2 times the force divided by the mass times the distance.
And then we could take the square root of both sides if we want, and we get the final velocity of this block, at this point, is going to be equal to the square root of 2 times force times distance divided by mass.
And so that’s how we could figure it out.
And there’s something interesting going on here.
There’s something interesting in what we did just now.
Do you see something that looks a little bit like work?
Well sure.
You have this force times distance expression right here.
Force times distance right here.
So let’s write another equation.
If we know the given amount of velocity something has, if we can figure out how much work needed to be put into the system to get to that velocity.
Well we can just replace force times distance with work.
Right?
Because work is equal to force times distance.
So let’s go straight from this equation because we don’t have to re-square it.
So we get vf squared is equal to 2 times force times distance.
That’s work.
Took that definition right here.
2 times work divided by the mass.
Let’s multiply both sides of this equation times the mass.
So you get mass times the velocity.
And we don’t have to write– I’m going to get rid of this f because we know that we started at rest and that the velocity is going to be– let’s just call it v.
So m times V squared is equal to 2 times the work.
Divide both sides by 2.
Or that the work is equal to mv squared over 2.
Just divided both sides by 2.
And of course, the unit here is joules.
So this is interesting.
Now if I know the velocity of an object, I can figure out, using this formula, which hopefully wasn’t too complicated to derive.
I can figure out how much work was imputed into that object to get it to that velocity.
And this, by definition, is called kinetic energy.
This is kinetic energy.
And once again, the definition that Wikipedia gives us is the energy due to motion, or the work needed to accelerate from an object from being stationary to its current velocity.
And I’m actually almost out of time, but what I will do is I will leave you with this formula, that kinetic energy is mass times velocity squared divided by 2, or 1/2 mv squared.
It’s a very common formula.
And I’ll leave you with that and that is one form of energy.
And I’ll leave you with that idea.
And in the next video, I will show you another form of energy.
And then, I will introduce you to the law of conservation of energy.
And that’s where things become useful, because you can see how one form of energy can be converted to another to figure out what happens to an object.
I’ll see
