On the Test of Time Dilation Using the Relativistic Doppler Shift Equation
http://pubs.sciepub.com/ijp/3/3/2
Phys. Rev. Lett. 113, 120405 – Published 16 September 2014), an Ives–Stilwell type experiment,it was claimed that a conducted time dilation experiment using the relativistic Doppler effect on the Li+ ions resonance frequencies had verified, with a greatly increased precision, the relativistic frequency shift formula, derived in the Special Relativity from the Lorentz Transformation, thus indirectly proving the time dilation predicted by the Special Relativity. The test was based on the validation of an algebraic equality relating a set of measured frequencies, and deduced from the relativistic Doppler equations. In this study, it was shown that this algebraic equality, used as a validation criterion, did not uniquely imply the validity of the relativistic Doppler equations. In fact, using an approach in line with the referenced study, it was revealed that an infinite number of frequency shift equations would satisfy the employed validation criterion. Nonetheless, it was shown that even if that claim was hypothetically accepted, then the experiment would prove nothing but a contradiction in the Special Relativity prediction. In fact, it was clearly demonstrated that the relativistic blue shift was the consequence of a time contraction, determined via the light speed postulate, leading to the relativistic Doppler formula in the case of an approaching light source. The experiment would then be confirming a relativistic time contraction. It was also shown that the classical relativity resulted in perceived time alterations leading to the classical Doppler Effect equations. The “referenced study” result could be attributed to the classical Doppler shift within 10 % difference.]]>

Let Your Success be BIIG: A New Paradigm for Problem-Solving in Science

decode, solve, and analyze. Despite the differing formats, each textbook provides an explanation for each step, however in the process it fails to clearly mention the finer details or attributes of each step in arriving at the solution. The objective of this study was to develop a streamlined process in problem-solving that enhances the students’ learning experience in science. The BIIG problem-solving strategy is a new method of approaching real-world word problems in science in a simple, rational way with clarity and sufficient depth. The thought process in the BIIG method consists of four elements represented by four letters: “B” is associated with the numbers and units, “I” is associated with the variables, next “I” is associated with the contextual information, and “G” is associated with the actual presentation of the solution. The elements described in this article can be applied to any problem-solving format, thereby making it a universal method. Based on both internal and external empirical evidence, it shows that the model is supportive for the students’ problem solving skills. The results indicate that starting with an initial interest level in Physics of only 28%, the students developed appreciation for the subject significantly (76%) and were highly satisfied with the assessment of their work (87%). The BIIG problem-solving method provides much needed skills for improving science education from K-12 schools to colleges, universities and institutions worldwide.]]>

Natural Radioactivity in Soil Samples in Nineveh Province and the Associated Radiation Hazards
http://pubs.sciepub.com/ijp/3/3/6
226Ra, ^{232}Th and ^{40}K in soil of Nineveh zone, Nineveh province, Iraq were measured by using gamma-ray spectrometry based on high-purity germanium detector. The specific activity of soil samples ranged from 16.21 to 38.83 Bq/kg with an average of value of 32.52±6.48 Bq/kg, 8.53 to 28.37 Bq/kg with an average of 20.30±5.36 Bq/kg, 236.03 to 613.11 Bq/kg with an average of 378.93± 123.29Bq/kg, and 2.18 to 17.92 Bq/kg with an average of 8.17± 5.55 Bq/kg for ^{226}Ra, ^{232}Th, ^{40}K and ^{137}Cs respectively. The study also examine some radiation hazard indices such as Radium equivalent activity (R_{aeq}), Absorbed gamma dose rate (D), External hazard index (H_{ex}), Internal hazard index (H_{in}) and gamma index (I_{γ}). These calculated hazard indices to estimate the potential radiological health risk in soil. The radium equivalent activity average (R_{aeq}) was less than the permitted value (370 Bq/kg). The average absorbed dose rate value also less than the permissible limit of 55 nGy/h. The external hazard index, internal hazard index and gamma index of soil samples were less than unity.]]>
