    Discussion The aim of this study was to investigate if age and gender are associated with children’s understanding of the earth’s structure. It was hypothesised that: older children will have a better scientific understanding of the structure of the earth compared to younger children, boys will have a better scientific understanding of the structure of the earth compared to girls, and younger children will construct different mental models of the earth compared to older children. The results of…

    magnitude in the disk(s) and ultimately lowers the area of operating hysteresis loop. Furthermore, for a thick disk, the radial component of flux cannot be disregarded in comparison with its circumferential component. In fact, such a two-dimensional field distribution will affect the overall performance of the motor. Also, It is clear from Fig. 6 8 that motors with thick disk require higher terminal voltage to produce a given…

    Review of Stacking Interactions of Nucleobases: NMR Investigations by H. Sapper and W. Lohmann Introduction Nuclear magnetic resonance (NMR) spectroscopy is often a very useful tool to identify organic molecules based on the atomic nuclei interactions with their environment. Recent advances have made use of the technology in protein, nucleic acid, and complex natural products structure identification. [1, 2, 3] Its origins lie in the works of Felix Bloch and Edward Purcell, who used the…

    the domains behave like a tiny little bar magnets just like the kind you have probably played with at school. The needle of a compass is also a bar magnet, and we know what this does: it points north because it likes to line itself up with the magnetic field of the earth. "However, if you bring the needle close to another…

    1.Magnetic resonance imaging uses the property of Nuclear Magnetic Resonance to take the image of nucleus has magnetization of its own and in MRI scanner patient is placed between a large magnet. This allows nucleus of atoms to align themselves according to their magnetization which leads to the production of magnetic field which is noticed by MRI scanner. This is how magnetic resonance imaging exploits the magnetics properties of the nucleus. 2. Sound waves are longitudinal waves and they…

    1. What are the issues in the upcoming negotiation? • The price that the Magnetic Advances division is willing to pay for the rights to Z-25 is one of the main issues in this negotiation. • Another issue is to whom Magnetic Advances is allowed to sell to, if we at Audio Components decide to sell the rights. Whether they are allowed to sell to Audio Components competitors specifically or El-Tek competitors as a whole. These prohibitions are key value drivers in any potential deal. This is to…

    symbol I and called its nuclear spin. This spin is then determined by its quantum number, which is represented by the symbol S. Each nuclear spin is associated with a magnetic moment. When this moment is placed in an external magnetic field, these spin states differ in magnetic potential energy. If placed in a static magnetic field with a small amount of spin polarisation however, certain radio frequency signals can allow a transition between spin states, with some of the spins being placed in a…

    society, especially tattoos. One writer says, “Permanent tattooing is the process of body modification by deposition of a pigment into the dermis” (Simunovic and Shinohara 525). In the past three decades, magnetic resonance imaging (MRI) has become increasingly popular in the medical field. Magnetic resonance imaging is a type of medical imaging that is non-invasive and safe in most cases. However, in some cases, patients with tattoos who have undergone MRI scans have experienced first and…

    Introduction: The lab experiment on Fabrication and Microwave Frequency Measurement of a ring Resonators was about finding the relative dielectric constant and the response of a ring resonator. These values are found by using a ring resonator and setting a frequency signal to the ring to resonate the signal. This lab also shows how to make the ring resonators from paper or any type of electric device from fabrication. Fabrication is used to print electric devices such as printed circuit boards.…
