Abstract

Laser-Induced Breakdown Spectroscopy (LIBS) is a spectroscopic method is highly reliable for atomic spectrochemical analysis both qualitatively and quantitatively. To achieve this, be aware of the detection parameters, one of which is a function of the atom emission intensity of detection delay time. In this study, plasma is generated by focusing the Nd-YAG laser (1064 nm, 7 ns) on the surface of solid Cu sample with 99.99% purity level at 1 atm pressure air environment. Plasma emission spectrometer was arrested by elements of Cu + HR 2500 with specifications: (wavelength range 200-870 nm, resolution 0.1 nm (FWHM), 7 detector CCDs with a combined 14.336 pixels) with variation detection delay time 0, 0.5, 1, 1.5, and 2 microseconds after the plasma formation and the energy varies the 60-160mJ. The data showed that the value of the Cu atom emission intensity 521.8 nm of the most highly visible on detection delay time decreased to 0.5 microseconds and detection delay time 2 microseconds. Based on these data it can be concluded that the characterization of the elements Cu to calculate the intensity was in the range of 100-140 mJ laser energy and time delay detection of 0.5 microseconds.

Abstract

The research on the influence of magnetic field on the number of erythrocytes in the rat(Rattusnorvegicus) had done. The study was conducted using Rats aged approximately three monthswith a body weight between 150 gr-300 grinterval. Rats were given exposure to magnetic fieldsvarying from 1830 gauss to 5220 gauss interval by using500 and 500 gauss to 3500 gauss interval byusing765 for 6 hours in 3 days. The research has been showed there some data are the above resultspecially on the decrease of erythrocytes number. And other some data that has increased. The aboveresult speciallyon the decrease of erythrocytes number presumably the composition of it dominated byelements iron (Fe) were classified as ferromagnetic and non-linear are caused. On the recovery timehas been set the white rat data showed some recovery time close to 5 days, more than 5 days.

Abstract

On the research effect of duration of exposure to the magnetic field to the number ofleukocytes in the rat (Rattus Norvigicus) are observed. Magnetic fields interval used in thisstudy is 300 Gauss till 500 Gauss with varying exposure time there are 2 hours per day, 3hours, 4 hours, 5 hours and 6 hours each day for three days and the recovery period of 5days was assumed. Based on the results. The leukocytes number of the rats were givenexposure to a magnetic field tends to increase after a recovery period tends to decrease thenumber of leukocytes or nearly normal. For N > 1 means the recovery takes over five days,as the number of leukocytes is still far above normal. For N < 1 recovery time is estimatedthat nearly five days, as the number of leukocytes gradually approaching normal.
