Hi,
While there have been proposals that environmental factors including viruses such as coxsackie B4 could be a trigger for autoimmune destruction in genetically susceptible individuals, there is actually no conclusive evidence that coxsackie B4 is required for the initiation of diabetes...
Fundamentally, most drugs aim to affect processes in a particular part of the body that may be functioning abnormally. In most cases, the targeted process often exists in many other parts of the body and so the drug will affect all areas, even in the non-target areas.
Furthermore, all drugs...
Hi Hisham.i,
What bobze said was correct but I think you may have the misunderstanding that nerves "branch" like a tree. Like he said try to think of them as a braided rope.
The smallest unit of a nerve is the axon of the motor neuron. A single nerve fibre such as the median nerve of the arm...
Woops I just realized that none of the equations showed up. Sorry! Let me try again with latex this time.
The equation was:
x^2 y'' - 5xy' + 5y = x^6 sinx
I used variation of parameters by hand and found this solution:
y = C_1 x + C_2 x^5 -180 x cosx + 90 x^3 cosx - 7 x^5...
Hi, I was solving the following second order ODE:

I used variation of parameters and found this solution...
Yes you're right, there is gravity pulling vertically down, and there are contact forces with the bucket. But since the bucket feels centripetal force into the circle, the water will be overall pushed towards the centre of the circle by the walls of the bucket, hence the water feels a...
As Jay mentioned, you don't need the force diagram for the pulley since all it does in this question is change the direction of a force. In this case, a force F causes a tension T in the rope, which is redirected to pull the block upwards.
Perhaps what you need is a force body diagram for the...
Hi evidenso,
Blood consists of about 50% water, and the rest are blood cells. Freezing the water will cause ice crystals to form, which will subsequently kill the blood cells (kinda like ice shards popping balloons). However, this won't be apparent until you thaw the blood.
If you're doing...
That's a very tough question with potentially allooot of explanation that a geneticist pretty much devotes his career to. You'll want to understand more about genetics and biochemistry. I'll try to keep this brief and very simple (Correct me if I'm wrong on anything).
Basically, genes are like...
Are you looking for an exact number? I have no idea but you are welcome to be the first to count it and possibly take an average across many different databases! (which as you said, will arrive at different opinions regarding categorisation of a disease).
As an educated guess from the ICD...
Hmm.. in the time I've had to think about this, I could only see one way to approach this, and it probably isn't the simplest approach.
As you said, you need to find the intersection between the projectile path and the line that represent the hill. A projectile takes the path of a parabola...
It depends on what type of scar you are trying to heal. I think glycolic acid peels are used mostly for facial blemishes such as acne scars. These scars are usually very superficial and involve a thin layer of dead skin cells and collagen. Glycolic acid would work for most superficial scars but...
What you need to do is draw a force diagram and write down all the horizontal and vertical components of tension as a result of the mass.
Next, you need to use Newton's second Law and find the net force in both horizontal and vertical directions.
Just remember that net force (vector sum of...
Maybe it's got to do with the wind? Maybe the wind often blows in a southerly or northerly direction in the place they got the google Earth images, and the cows like to face it... or away from it.
