so that you can compare the results with the real medicine.
Three phase ovens are made for home use. It is important however to know if the home is wired for three phase or for single phase.
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
is 3 phase Meter electicity to for the measurement of elektricity 3 phase.
Yes, three phase CDP (Central Distribution Panels) all use breakers to distribute the three phase supply voltage to their respective loads.
yes you can
Yes, the use of a placebo in a clinical trial can be justified, as it serves as a control that helps determine the effectiveness of a new treatment compared to no treatment. Placebos can help account for the psychological effects of receiving treatment, known as the placebo effect, and ensure that observed outcomes are due to the treatment itself rather than participants' expectations. Additionally, using a placebo allows researchers to adhere to ethical standards by providing a clear comparison, which can enhance the reliability of the trial's results.
Placebo is a dose of an inactive pill or other type of drug, used in drug testing to control for psychological effects of taking medicine. Its use is debated in clinical trials, but the practice of prescribing placebo for patients is far more controversial.
Generally as a noun.Example: He swallowed the placebo.It also works as "The Placebo Effect", and also the band Placebo.

Scientists use a placebo to check that the variable they are changing actually is responsible for the results they see. It is like a control experiment, allowing you to compare the trial with it to see if there is any effect. It also counteracts the "placebo effect". For example, this is when someone taking a drug calims they "feel better" despite the drug not actually having any effect. Therefore, by giving some test subjects a placebo and some the drug being tested and not telling them which is which, you can eliminate the placebo effect from the test.
Musical ones.
Oral glucosamine is commonly used for the treatment of osteoarthritis. Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis. Its use as a therapy for osteoarthritis appears safe, but there is conflicting evidence as to its effectiveness. A randomized, double-blind, placebo-controlled trial found glucosamine sulfate is no better than placebo in reducing the symptoms or progression of hip osteoarthritis.There are two main types of glucosamine, Glucosamine Sulfate and Glucosamine hydrochloride. In a placebo controlled trials of Knee pain the Glucosamine Hydrochloride failed to show superority over placebo (GAIT) but a similar trial of the Glucoasmine Sulfate showed superiority over placebo and paracetamol in the control of pain.
No. It makes use of the placebo effect, at best.
Although the name and use of placebo treatments dates back to ancient times, the phrase 'Placebo Effect' was first mentioned by the English physician Dr. T.C. Graves who wrote in 1920 that there appeared to be a "real psychotherapeutic effect" when treating patients with a placebo.
Well it depends on the type of trial. Often it would be unethical to use a placebo when there is already an established treatment for a condition. For example if you have a new form of cancer treatment it would be unethical to test the new treatment against a placebo because you would be denying the recommended treatment to a percentage of the patients. In this type of case the trial uses the new treatment and compares the efficacy against the accepted standard treatment.. Placebos would generally only be used where the effects are non-life threatening or it's a totally new treatment for an existing condition. For example when AZT was first trialled on AIDS patients they used a placebo control, the trial had to be stopped early because so many of the control group were dying and the control group were switched to AZT as well. Ethics not science dictated the early termination of this trial
Placebos are used in experiments to distinguish the effects of a treatment from those that might occur simply due to expectation or the act of receiving medical attention. By comparing the responses of participants who receive a placebo with those who receive the actual treatment, researchers can determine the true effectiveness of the treatment.
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
