The Basics of NMR Chapter 1 INTRODUCTION [pic] NMR Spectroscopy Units Review [pic] NMR Nuclear magnetic resonance‚ or NMR as it is abbreviated by scientists‚ is a phenomenon which occurs when the nuclei of certain atoms are immersed in a static magnetic field and exposed to a second oscillating magnetic field. Some nuclei experience this phenomenon‚ and others do not‚ dependent upon whether they possess a property called spin. You will learn about spin

Ventilation The air around us is warmed up by everyday activities such as breathings‚ washing and drying clothes‚ cooking food‚ running electric motors and using electric lights. The composition of the air around us can also be changed by: chemical pollutants‚ pollen‚ dust‚ tobacco smoke and odors. These changes will make the air stale if it stays in a confined space. This may make us feel hot and sticky and can make us less efficient at work. To stop the air around us from being stale we

Since the flux is sinusoidal‚ r.m.s = (form factor*average e.m.f )/turns But form factor = (r.m.s value)/(average value) =1.11‚ Then r.m.s value of E.m.f = 1.11*4F*max.Flux = 4.44F*max.Flux‚ But max .flux = B_m*A r.m.s value of E.m .f in primary turn (Tp) = 4.44F*B_m*A*T_p NOTE: Bm is assumed to be 15000Wb/m. F = Frequency of A.C input/ Output F=50 Hz By introducing stacking factor (10-8) and Tp factor (0.9) then we have Number of turns per volt = N_T/V =7/A =7/3.75=1.87turns/volts

Low Power FM Transmitter Rod Elliott (ESP) Share| [pic] Introduction This article should satisfy those who might want to build a low power FM transmitter. It is designed to use an input from another sound source (such as a guitar or microphone)‚ and transmits on the commercial FM band - it is actually quite powerful‚ so make sure that you don’t use it to transmit anything sensitive - it could easily be picked up from several hundred metres away. The FM band is 88 to 108MHz‚ and although it

Mexican culture The Mexican culture has been around for years. Growing slowly and gaining new things to make the culture bigger. What does the Mexican culture consist of? The Mexican culture is known for its family. Families are always close and do events to stray united. This is a big meaning for the culture because when you are distant from your family you are an outsider to them now. Being close to your family means love‚ care‚ and prosperity. You stay with your family until you are married

works as shown in the diagrams below. DC motors. A simple DC electric motor. When the coil is powered‚ a magnetic field is generated around the armature. The left side of the armature is pushed away from the left magnet and drawn toward the right‚ causing rotation. The armature continues to rotate. When the armature becomes horizontally aligned‚ the commutator reverses the direction of current through the coil‚ reversing the magnetic field. The process then repeats. Single-phase AC induction motors

other‚ i.e.‚ if the left secondary windings is in the clockwise direction‚ the right secondary windings will be in the anti-clockwise direction‚ hence the net output voltages will be the difference in voltages between the two secondary coil. The two secondary coil is represented as S1 and S2. Esteem iron core is placed in the centre of the cylindrical former which can move in to and fro motion as shown in the figure. The AC excitation voltage is 5 to 12V and the operating frequency is given by 50
