they go to their gp and the first thing they are prescribed is antidepressants rather than hrt. there will be women concerned about changes in mood, physical and emotional changes, what advice would you give? the emotional changes, what advice would ou rive? , , , ., , you give? the first thing is please track our you give? the first thing is please track your symptoms. you give? the first thing is please track your symptoms. you - you give? the first thing is please track your symptoms. you can - you give? the first thing is please track your symptoms. you can do | you give? the first thing is please - track your symptoms. you can do that with an app developed and get that. talk to a gp, talk about your periods openly and say what your pattern is like. if you are on a contraceptive like the coil, that is suppressing periods, we diagnose by symptoms alone. women below a5 we give them a blood test but it is not accurate enough, it will always be our symptoms. accurate enough, it will
velocity mode of precision laser called an interferometer shown here in green is used to measure the position and velocity of the coil. the aim is to measure the voltage that is created in the process. then we need gravitational acceleration small g. 9.81 meters per 2nd per 2nd if you know all these things very precisely you can calculate the numerical value for h. the math isn t complicated in reverse if you know the value of h. the planck constant you can specify a kilogram. the planck scales from germany will work in exactly the same way they re basically a water bottle and on the left is the laser interferometer on the right is the balance based on the principle of electromagnetic force compensation but it s
a handful of these scales worldwide this one is in the united states at the national institute of standards and technology. the high precision scale is based on the principle of electromagnetic force compensation this is how it works the gravitational force of a test mass is balanced with an electromagnetic force the magnetic field is provided by a permanent magnet a coil of wire is immersed in that field. it s like a coil in a loudspeaker and the coil is in a permanent magnetic field an electrical current is run through it to generate a force that force is used to balance the downward force of the weight it s a way to measure weight using an electrical current of. a mission in other words the electrical current is adjusted until the upward force on the coil perfectly balances the downward force of the weight the 2nd step is called the
