Statistical Study of foF2 Diurnal Variation at Dakar Station from 1971 to 1996: Effect of Geomagnetic Classes of Activity on Seasonal Variation at Solar Minimum and Maximum

Author(s): Ali Mahamat Nour, Ouattara Frédéric, Zerbo Jean Louis, Gyébré Aristide Marie Frédéric, Nanéma Emmanuel, Zougmoré François

The statistical study of F2 layer critical frequency at Dakar station from 1971 to 1996 is carried out. This paper shows foF2 statistical diurnal for all geomagnetic activities and all seasons and that during solar maximum and minimum phases. It emerges that foF2 diurnal variation graphs at Dakar station exhibits the different types of foF2 profiles in African EIA regions. The type of profile depends on solar activity, season and solar phase. During solar minimum and under quiet time  Continue reading

The “Colour Family Drawing Test”: Assessing Children’s Perception of Family Relationships. Studies on Mental Health and Cross-Cultural Comparisons

Author(s): Valeria Biasi1, Paolo Bonaiuto, James M. Levin

We apply the Colour Family Drawing Test, as a development of the traditional black and white test, for cross-cultural comparison. The participants, aged 7 – 10 years, both genders, were examined individually. Each subject sat at a single table with a white rectangular card of standard size, 24 well-sharpened colour pencils, a black pencil, an eraser and other appropriate tools. S/he received this verbal instruction: “Draw your family”. The procedure was firstly applied to 120 participants Continue reading

The global diverse society necessitates that teachers develop cultural competency and use authentic resources for teaching. This article presents classroom-tested materials for teaching elementary students about aspects of Russian culture, developed by a native Russian and two education professors. Multiage, multi-racial American Midwestern students from a homeschooling cooperative learned vocabulary and concepts with statistically significant increases from pretest to posttest and a large effect size. The lessons began with recognition of human commonalities between Russian people and Americans, in accordance with omniculturalism theory. Lessons then highlighted and celebrated cultural differences through an exploration of Russian literature and culture. Culminating creative craft-making activities included simulating a Gzhel porcelain statue in white air-dry clay with blue markings, making a pop-up version of a matryoshka nesting doll set, constructing a papier-maché building with Continue reading

PM2.5 Pollution and Risk for Lung Cancer

Author(s): David Hu, Juyuan Jiang

PM2.5 Pollution and Risk for Lung CancerThis study is focused on the linkage between lung cancer incidence rates and PM2.5 pollution. Researches conducted by leading research organizations in U.S. and Europe were reviewed and analyzed, and strong evidence exists that elevated fine particulate air pollution exposures are associated with significant increases in lung cancer mortality. The linkage between fine particulate air pollution and lung cancer motility is observed even after controlling for cigarette smoking, Continue reading

Discussion on Issues of Inheritance of Internet Virtual Property

Author(s):Pengfei Ji

With the increasingly close connection between the Internet and citizens, the Internet virtual property is increasing in large amount. Although the viewpoints the parties hold about “virtual property” are different in the judicial practice, the analysis from the perspective of legal principle indicates that virtual property should be included in the legacy as “legitimate property” and legally inherited by its successor without doubt. In addition, Continue reading

Detection and Mapping of Water Quality Variation in the Godavari River Using Water Quality Index, Clustering and GIS Techniques

Author(s): Indrani Gupta, Awkash Kumar, Chandrakant Singh, Rakesh Kumar

The objective of this research is to develop a tool for planning and managing the water quality of River Godavari. This is achieved by classifying the pollution levels of Godavari River into several categories using water quality index and a clustering approach that ensure simple but accurate information about the pollution levels and water characteristics at any point in Godavari River in Maharashtra. The derived water quality indices and clusters were then visualized by using a Geographical Continue reading

A New Method of Estimating Wave Energy from Ground Vibrations

Author(s): K. Ram Chandar*, V. R. Sastry


Performance of explosive energy is rated in a number of ways, obtained either from theoretical calculations or from experimental tests. However, it is difficult to determine the amount of the explosive energy transferred to the rock and converted into efficient work in the application of rock blasting. Although measurement of some of the effects of explosive energy in rock mass is ground vibration, noise, etc., which are usually Continue reading

Electric Vehicles Analysis inside Electric Mobility Looking for Energy Efficient and Sustainable Metropolis

Author(s): Miguel Edgar Morales Udaeta, Carolina Attas Chaud, André Luiz Veiga Gimenes, Luiz Claudio Ribeiro Galvao

This paper aims to study and evaluate electric mobility over time, focusing on the development of the electric car. Methodologically, in order to accomplish this intent, the characterization of the electric vehicle (EV) is made based on the variables which determine its performance, such as: assessment of speeds, distance traveled, analysis of facts related to the energy source (electro-chemical accumulators) and analysis of the determining system of electric mobility (the electric engine as a function Continue reading

The Third Polarization of Light

Author(s): Richard A. Hutchin


A SQUID (Superconducting Quantum Interference Device) measures the magnetic flux inside the loop using the voltage across a pair of Josephson junctions. The signal goes through one oscillation every magnetic flux quantum (h/2e) and is the most sensitive magnet field detector in the world. It measures the magnetic flux even when no magnetic or electric field touches any part of the circuit.
A SQUID (Superconducting Quantum Interference
Device) measures the magnetic flux inside the loop using the voltage across a pair of Josephson junctions.

We are all taught that there are only two polarizations of light because Maxwell’s equations only support two polarizations. This is mathematically true for the electromagnetic fields, but we have learned since the days of Maxwell that the “real” electromagnetic field is not the electromagnetic field tensor Fμv (composed of Electric and Magnetic field terms) but rather the electromagnetic vector potential Aμ. When considered carefully, this requires a third polarization of light with very unusual properties. This third polarization of light does not generate electric or magnetic fields but should be detectable by its impact on supercurrents or quantum interference. It is also unavoidable since it automatically appears under Lorentz transformations to different moving frames. Continue reading
