Mission simulator test data
A real time mission simulation test program of nickel cadmium cells, performed in conjunction with the Anik 1A2 satellite, is reviewed. Simulation of the temperature profiles, the electrical profiles, the depth of discharge, and the rate of charge and discharge is reported. The type of separator used in the cells and the transfer of electrolytes during overcharge are discussed
The Data Breach Epidemic: A Modern Legal Analysis
This Note sheds light on the major legal issues surrounding the numerous data breaches that plague our modern technology-driven society. Current laws in the United States vary widely in how they handle the resolution of harm to unsuspecting victims of data breaches. The issue of Article III standing is commonly at the forefront of the conflict and discussion in this area, which has resulted in a substantial circuit split in the United States. The newly enacted California Consumer Privacy Act will likely have a major impact in this area of the law and will undoubtedly influence how consumers’ personal information is handled in the years to come
Further research on profitable globalization and the ethical dilemma of U.S. job loss
In theory, profitable globalization practices in developed, industrialized countries share a symbiotic relationship with cheaper offshore human resources in third-world, poor, or underdeveloped nations. A short case study of Wal-Mart Stores, Inc. is given, which examines Wal-mart’s increased use of the cheaper Chinese workforce. By seeking out a lower cost labor force in a yet developing country, an ethical dilemma arises in that the business in the industrialized nation must ignore or disregard the job loss this decision creates within the borders of the home nation. Political and philosophical differences have led opponents to create an anti-thesis known as anti-globalization. The antiglobalization movement is apprehensive toward the cultural impact profitable globalization has on the poor and underdeveloped countries. This paper compares globalization versus Marxist thought in which some of the anti-globalization opinions are founded. By exploring a variety of sources and looking for matching patterns or ideas that give relevance to the topic, several sources were used in this study including the review of scholarly journals, engaging video documentaries, news reports, labor statistics, economic texts, and the concept of trade union impact on the work force. This paper establishes a theory that this profitable globalization through the offshore outsourcing of labor to foreign businesses is having a derogatory effect on the United States unemployment statistics

Effects of weak extremely low frequency magnetic fields on calcium/calmodulin interactions.
Journal ArticleMechanisms by which weak electromagnetic fields may affect biological systems are of current interest because of their potential health effects. Lednev has proposed an ion parametric resonance hypothesis (Lednev, 1991, Bioelectromagnetics, 12:71-75), which predicts that when the ac, frequency of a combined dc-ac magnetic field equals the cyclotron frequency of calcium, the affinity of calcium for calcium-binding proteins such as calmodulin will be markedly affected. The present study evaluated Lednev's theory using two independent systems, each sensitive to changes in the affinity of calcium for calmodulin. One of the systems used was the calcium/calmodulin-dependent activation of myosin light chain kinase, a system similar to that previously used by Lednev. The other system monitored optical changes in the binding of a fluorescent peptide to the calcium/calmodulin complex. Each system was exposed to a 20.9 microT static field superimposed on a 20.9 microT sinusoidal field over a narrow frequency range centered at 16 Hz, the cyclotron frequency of the unhydrated calcium ion. In contrast to Lednev's predictions, no significant effect of combined dc-ac magnetic fields on calcium/calmodulin interactions was indicated in either experimental system. are of current interest because of their potential health effects.

Improving Focality and Consistency in Micromagnetic Stimulation
The novel micromagnetic stimulation (μMS) technology aims to provide high resolution on neuronal targets. However, consistency of neural activation could be compromised by a lack of surgical accuracy, biological variation, and human errors in operation. We have recently modeled the activation of an unmyelinated axon by a circular micro-coil. Although the coil could activate the axon, its performance sometimes lacked focality and consistency. The site of axonal activation could shift by several experimental factors, including the reversal of the coil current, displacement of the coil, and changes in the intensity of the stimulation. Current clinical practice with transcranial magnetic stimulation (TMS) has suggested that figure-eight coils could provide better performance in magnetic stimulation than circular coils. Here, we estimate the performance of μMS by a figure-eight micro- coil, by exploring the impact of the same experimental factors on its focality and consistency in axonal activation. We derived the analytical expression of the electric field and activating function generated by the figure-eight micro-coil, and estimated the location of axonal activation. Using NEURON modeling of an unmyelinated axon, we found two different types (A and B) of axon activation by the figure- eight micro-coil, mediated by coil currents of reversed direction. Type A activation is triggered by membrane hyperpolarization followed by depolarization; Type B activation is triggered by direct membrane depolarization. Consequently, the two types of stimulation are governed by distinct ion channel mechanisms. In comparison to the circular micro-coil, the figure-eight micro-coil requires significantly less current for axonal activation. Under figure-eight micro-coil stimulation, the site of axonal activation does not change with the reversal of the coil current, displacement of the coil, or changes in the intensity of the stimulation. Ultimately, the figure-eight micro-coil provides a more efficient and consistent site of activation than the circular micro-coil in μMS
