Microstructures and Elemental Distribution of Magnetic Field Pre-Treated Fluted Pumpkin Leaf

AbstractThere is a scarcity of studies on the use of magnetic field for food pretreatment, especially in relation to a knowledge on the pretreatment at the level of microstructures and elemental distribution of food. Therefore, the effect of magnetic field pretreatment on the microstructures and elemental distribution (Na, K, Ca, Mg and Fe) of fluted pumpkin leaf was studied. Three types of magnetic field (static, pulse and alternating) in combination with varying magnetic field strength (5–30 mT) and pretreatment time (5–25 min) were used as variable factors. Fresh (untreated) and blanched samples were used for experiment control. After the pretreatment, all samples were dried at 50 °C and analysed in terms of microstructure and elemental distribution using scanning electron machine. Results showed that fresh and blanched samples of fluted pumpkin leaf exhibited microstructural features that were clearly different from samples pretreated by magnetic field. Pretreated samples showed contents of: 1.3–4.35% sodium; 1.20–3.42% potassium; 1.19–6.10% calcium; 0–5.10% magnesium and 1.22–6.62% iron. Changes in microstructures of samples caused by magnetic field pretreatment led consequently to better retention/improvement in elemental distribution in contrast to blanched and fresh samples in majority of cases.

The Magnetic Field

SummaryMeasurements of the radial velocities and magnetic field strength of β CrB were carried out. It is shown that there is a variability with the rotation period different for various elements. The curve of the magnetic field variation measured from lines of 5 different elements: FeI, CrI, CrII, TiII, ScII and CaI has a complex shape specific for each element. This may be due to the presence of magnetic spots on the stellar surface. A comparison with the radial velocity curves suggests the presence of a least 4 spots of Ti and Cr coinciding with magnetic spots. A change of the magnetic field with optical depth is shown. The curve of the Heffvariation with the rotation period is given. A possibility of secular variations of the magnetic field is shown.

Optical Rectification

Simultaneous effects of magnetic field, pressure and temperature on the exciton binding energies are found in a 9.0 1.0 6.0 4.0 GaAs P / GaAs P quantum dot. Numerical calculations are carried out taking into consideration of spatial confinement effect. The cylindrical system is taken in the present problem with the strain effects. The electronic properties and the optical properties are found with the combined effects of magnetic field strength, hydrostatic pressure and temperature values. The exciton binding energies and the nonlinear optical properties are carried out taking into consideration of geometrical confinement and the external perturbations.Compact density approach is employed to obtain the nonlinear optical properties. The optical rectification coefficient is obtained with the photon energy in the presence of pressure, temperature and external magnetic field strength. Pressure and temperature dependence on nonlinear opticalÂ susceptibilities of generation of second and third order harmonics as a function of incident photon energy are brought out in the influence of magnetic field strength. The result shows that the electronic and nonlinear optical properties are significantly modified by the applications of external perturbations in a 9.0 1.0 6.0 4.0 GaAs P / GaAs P quantum dot.
