My sister doesn't need one, but really wants a c-section. You can choose, right? Where can I find info on hospitals that allow this, if you can even choose.
How can you find out which hospitals let you choose a c-section?
First off. why would she choose to have one? they are not easier. Does she think it would be? She is mistaken. I don't think it's necessarily just the hospitals, it's the Doctors too. Most Doctors would not risk the health of the baby and Mother just because someone wants one unless they have had bad birth experiences before or complications or if they NEED one. A good Doctor would advise against it unless it was thought to be the safest option for the baby and Mother.
Reply:she would need to talk to her ob about it. why would she ever WANT a c-section? recovery is longer, scars, harder to loose the weight, painful afterwards. why would you want that? if she really badly wants one she needs to talk to her doc cause the hospital won't let her just pick unless doc says so or they need to.
Reply:Its really up to the doctor to decide, most doctors dont just let people opt for c sections if there is no medical reason. Those docs are really by the book, most of them are. She would just have to call around to different OB's
Reply:Its up to the doctor, not the hospital. Best of luck!
God Bless :)

How or where can I find out how many tons my air handler is rated for? A/C problem?
I am having trouble with my A/C. The blue pressure [and I may have this backwards] or freon pressure is 70psi, but the head pressure, or red gauge is at or close to 250psi and there is no leaks that I can find, the filter is clear, intake registers are all clear, the condensing unit outside is clean and free of obstruction. All of the dampers are fully open and airflow seems to be good [from all the vents], but id does not blow cold air. Instead, the coil freezes over. I have been told this could be due to a low freon/coolant pressure, or air obstruction but as far as I can tell along with the A/C service person it is not. He says I need a new system, but I am not convinced because though my system is a 10 seer system, it is only 7 years old. It doesn't look like I can access the underside of the coil to inspect it without tearing apart the air handler, so do I need a new one? Or can the coil be removed and serviced?
I would really appreciate any input and thanks in advance.

Check your air flow; make sure the belt is good if its belt driven, or the blower is tight on the shaft if it direct drive. Also check the the blower is not excessively clogged with dirt; this will decrease your air movement. You will need to check the evap coil for dirt or blockage also, do this ASAP. With those pressures, it is probably R22 for refrigerant, and they sound good. I think it is air flow, but it also can be air in the closed system, which would involve recovering the refrigerant,, changing the drier, putting a vacuum pump on it, and recharging it. Air exerts its own seperate pressure, and can give higher than normal readings.
Reply:Check the model number. They go by 12's. If you see a 24 in it it's a 2 ton. 30= 2.5, 36=3 and so on.
I would get a second opinion. There's so many electrical points that could go bad. I doubt you need a new system.
Reply:It sure sounds like an air flow or low freon problem. You may want to check to make sure the condensate drain is not plugged that can cause water to collect on the coil and freeze. To find the tonnage look for the model # on the unit and look it up on their website.
12,000 BTU per ton
400 CFM per ton
This info may actually be on the unit. This should be enough to figure out the tonnage. You can pull the coil to service it but usually there isnt much to service on a coil unless it is leaking.
Reply:Have the repair person evacuate the system,replace the drier, evacuate (leave on a vacuum pump 5 hours) recharge the system.
Reply:It could be low refrigerant but, if the suction pressure is 70psi and it's an R22 system, it should not be freezing. 70psi on the low side equals a saturated evaporator temperature of 41°. That means it would be impossible to freeze water on the coil. If the coil is flooding and there is a lot of pressure drop in the suction line you could see frost near the compressor.
Those pressures actually sound pretty good. On a really hot day that head pressure (250psi) might even sound a little on the low side if it's 100° outside.
Your numbers do not sound right for freezing the coil. Make sure everything is clean before you go any further. Maybe your filter is clean, but your evaporator is actually dirty anyway.
It's possible for dirt to build on an evaporator even if the filter has been change on a regular basis. Especially if you have been buying the 99 cent filters for the last 7 years.
With those kind of pressures and that kind of air flow nothing you are saying is making any sense. The air should be cool and there should be no frost. You need to redo your pressure checks.

How to find the Horizontal Shift, C, of sinusoidal equations?
I am unsure of how to find the Horizontal Shift, C, in a sinusoidal equation.
y = Asin(B + C) + D
I've been working through problems and looked at a few resources (books and online) to help me but most of them breeze through how to get the horizontal shift and I can't seem to find where the numbers come from.
Anyone have any examples or suggestions on resources I could use? I am able to find the other numbers but just need help with horizontal shift.
Any help is greatly appreciated.
How to find the Horizontal Shift, C, of sinusoidal equations?
The Horizontal shift of a sine graph is the C. To shift it C units to the left, you would have a positive C while to shift it C units to the right you have to have a negative C
y = Asin(B + C) + D

I am thinking about doing a science fair experiment but I need to find a way to measure Vitamin C?
I am doing an experiment on whether the amount of Vitamin C in a variety of drinks differ over time. However, I need to find a way in which I can measure the amount of vitamic C. How can I measure Vitamin C?

Sounds like a good experiment, Good Luck. The URL below gives the name of a place where you can buy a Vitamin C test kit. Every chemical supply houses have them, just tell them what you are doing and they will send you the exact kit you need.
Reply:There are premade kits for testing for Vit C, aka ascorbic acid

Where can I find drop c guitar chords?
I been looking on google for hours and I cant find anything that shows how to play chords in drop c (CGCFAD) on guitar. I only been finding standered tuning chords :(
Are there any websites that have chordfinders, chord charts, ect in drop c and not in standered tunning?

Why the hell have you done this??? It gave you nothing, and it's bad for the neck. I found one, but WHY??? So stupid what you've done. Sry.

Reply:nothing against slayer, but it looks like those are open C chords, not drop C. Drop C isn't that different than drop D, except of course it is a whole step down. If you're playing along to another guitar player in drop C, then you're all set. If you need to play along with something in standard tuning, you'd probably be best off just transposing the chord up a whole step in your head. For example, if you needed to play a chord that sounds like a D, you'd actually play an E chord (because you're down a whole step, so it's a D). So you can apply that logic to any major, minor, 7th and so on chord. And if you need to find some really specific chord on a chord chart, do the same thing - eg, if you need, say, a Cmaj7, search a standard tuning chart for a Dmaj7 (it will actually be Cmaj7 on your guitar because of the drop)
PS - I would recommend GHS Zakk Wylde Boomers for Drop C, but that's totally preference
