The Square of Rotational Energy and the Moment of Inertia for Pt (A=192 – 198) Isotopes
Abstract: The aim of the present work was to study the square of rotational energy of Pt (A=192–198) isotopes, depending on the energy levels E(L) and angular momentum (L), as has been the study of moment of inertia for same isotopes, depending on the energy transitions for spin sequences and angular momentum (L). All that has been found by using (IBM-1) program. After that, all of the data from theoretical work …

Statistical Analysis of Geomagnetic Activity and Solar Activity Features during Solar Cycle 23 & 24
Abstract: We present a statistical analysis of the geomagnetic storm (GMSs) with the solar activity features (Sunspot number (SN), H-α flare and coronal mass ejection (CME)) during solar cycle 23 and 24. Sunspot number (SN) shows good correlation with peak values of GMSs indices (correlations coefficient R= 0.76) while CME(R=0.59) and H-α (R=0.55) show moderate correlation. So we conclude that GMSs have good correlation with solar activity features during major geomagnetic …

Modelling and Design of Punch and its Operation on Sheet
Abstract: Punching of a sheet is widely used in manufacturing industries due to its applications. It can be used to give the required shape or to process a hole. It can be very large or small depending upon the application required. A lot of household items are being made by punching operation. Punching involves parts such as punch which applies the force and is motion, sheet on which load is being …

Validation of Atomic Absorption Spectroscopy (AAS) for Trace Elements Analysis of Environmental Samples
Abstract: The investigation focused on the validation of the methodology used in determining the presence of specific trace elements in environmental soil concern. Atomic Absorption Spectroscopy (AAS) available in Gombe State University, Nigeria was employed in analyzing the elemental concentrations on the certified values in three reference materials obtained from the International Atomic Energy Agency (IAEA) and National Institute of Standards & Technology (NIST). The elements determined were Cd, Co, Cr, …
