Niels Bohr developed hismodel of the atomic structure in 1913 that succeeded in explaining the spectral features of hydrogen atom. In the process, he incorporated some non-classical features such as discrete energy levels for the bound electrons, and quantization of their angular momenta. 相似文献

A study of iron, zinc, copper and selenium concentration levels was carried out in three compartments namely, maternal serum (MS), colostrums and cord blood serum (CS) of healthy Indian mothers (n = 42) who delivered healthy normal neonates without any congenital anomalies at Bhabha Atomic Research Centre hospital, Mumbai. Fe, Zn, Cu in maternal serum, cord blood and colostrums were estimated by flame atomic absorption spectrometry while Se was determined by graphite furnace absorption spectrometry. It was seen that there was a significant difference in the level of trace elements in the three compartments. The average levels of Fe in the three compartments were 1,132 ± 519, 2,312 ± 789 and 1,183 ± 602 μg/L while Zn was 514 ± 149, 819 ± 224 and 7,148 ± 2,316 μg/L respectively. Mean Cu values were 1,614 ± 295, 301 ± 77 and 392 ± 174 μg/L respectively while Se values were 70 ± 15, 36 ± 10 and 23 ± 8 μg/L respectively. The results indicated a positive correlation of Fe and Zn concentrations in MS versus CS which were (r = 0.386), (r = 0.572) respectively and Fe levels in MS and colostrums (r = 0.235). A few inter element correlations were found within compartments. Zn and Se showed a negative correlation in both MS (r = −0.489) and colostrums (r = −0.258) while a positive inter correlation of Fe and Zn was seen in MS (r = 0.44) and in CS (r = 0.54). This study gave us an overview of the serum and colostrum values of mother and neonates in Indian population, data of which are scarce. 相似文献

We present in two parts, a mathematical theory of conservation laws using the language of physics. In Part I we explain the concept of a special type of nonlinearity which appears in an important class of evolutionary processes governed by hyperbolic partial differential equations. For simplicity, we develop the theory using a simple model equation. We show that it is possible to extend the concept of solutions with discontinuities with the help of a conservation form of the equation. 相似文献

We discuss some errors in The Feynman Lectures on Physics related to the concept of symmetry. We also suggest a possible correction to Fig.1.4 of Vol. I. The discussion may be useful for students of crystallography, solid state physics and solid state chemistry. 相似文献

Nepal is currently the focus of much attention in the form of aid and advice from the international community, and policy documents and proposals recognise the importance of education opportunities for girls and women as one of the cornerstones for successful development. Our concern was that in spite of policy intentions few real strategies exist with regard to the implementation of policy. Our research focused on the textbooks and school organisation patterns currently in use in Nepalese primary schools as this focus has not to date been addressed in Nepal. In suggesting short‐ and long‐term strategies as a response to the research findings, we hope that these suggestions may make a small contribution to educational research in Nepal.

Patent statistics may be indicative of growth and evolution of technologies in relation to a scientific field or sub-field of research. In this paper annual growth of patents in the field of superconductivity has been studied. The data in five-yearly cumulation have been set against research papers on superconductivity to show comparative growth of basic research and technological development. Two simple indicators have been devised to understand the apparent influence of basic research on technology and trends of relative growth. 相似文献

Current study is conducted to evaluate method verification of two locally available kits manufactured by DSI & BIORAD for quantitative estimation of Hepatitis B virus antibodies in human normal immunoglobulin by using International standard of National Institute of Biological Standards and Control. Four analyst perform five sets of test in duplicate analysing accuracy, precision, and limit of detection, sensitivity and specificity. Our results suggest that both DSI and BIORAD kits fulfil the validation criteria and are sensitive to detect up to 10 mIU concentration precisely and accurately. DSI kit is more precise at concentration 100 mIU and economically 4–5 times cheaper in local market; on the other hand, BIORAD kits provide larger detection range up to 1000 mIU. 相似文献
