Total Electron Content (TEC) Variations and Correlation with Seismic Activity over Japan

doi:10.22186/jyi.31.4.13-16 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References |PDF Abstract Earthquakes are extremely dangerous physical phenomena. The ability to properly forecast them would go a long way in reducing the damage they cause. One earthquake forecasting method being researched uses the ionospheric Total Electron Content (TEC). Our investigation used TEC data from 2011 during certain days near and on the date of […]

Chemical Reduction and Deposition of Nanostructured Pt–Au Alloy

doi:10.22186/jyi.31.4.7-11 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References |PDF Abstract Nanostructured metal alloys made up of Pt and another metal are more efficient in catalysing reactions than pure Pt nanoparticles. However, few studies have investigated low heat, solvent-free chemical deposition techniques of nanostructured metal alloys. This paper investigates the deposition of Pt–Au nanostructured metal alloy on fluorine-doped tin oxide glass via the […]

Probability Current and a Simulation of Particle Separation

doi:10.22186/jyi.31.4.1-6 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References |PDF Abstract The structure of scattered wave fields and currents is of interest in a variety of fields within physics such as quantum mechanics and optics. Traditionally two-dimensional structures have been investigated; here we focus on three-dimensional structures. We make a generic study of three dimensional quantum box cavities, and our main objective is […]

Interview with a Developmental Biologist: Dr Jean-Léon Maître

Dr Jean-Léon Maître is a group leader in the Genetics and Developmental Biology unit at Institute Curie in Paris, one of the leading medical and biophysical research centres in the world. Dr Maître earned his PhD at the Max Planck Institute for Cell Biology and Genetics in Germany, and the Institute of Science and Technology […]

The Quest for Smarter Dust

The 1996 film Twister follows a group of storm chasers who are designing a revolutionary device to understand tornados and create more advanced warning systems. This device would release hundreds of small sensors into the heart of a tornado, collecting structural data from within these natural phenomena. Of course, the movie’s plot is fictitious, but what if […]

How Prenatal Exposure to Marijuana Affects Executive Functioning in Young Adults

Every year, 211 million pregnancies occur around the world (WHO, 2007), and during pregnancy, one of the most commonly used drugs is marijuana (“Alcohol, drugs, and babies: Do you need to worry?” 2005). There has been an increase in the amount of pregnant women smoking marijuana to aid their morning sickness. However, marijuana use while […]

If You Give A Mouse A Movie

We have all heard Descartes’ famous quote “cogito ergo sum”—I think, therefore I am. But what does it mean to think? Or perhaps, what is it to think? To answer this question, the Allen Institute for Brain Science has released the Allen Brain Observatory1, a collective, standardized “survey of cellular activity in the mouse visual […]

Dieticians and Nutrition: Are you what you eat?

For many people, “eating healthy” involves more than just avoiding excess fat and adding in plenty of fruits and vegetables. People of different ages, activity levels, and health backgrounds  all have unique nutritional needs. Whether it be a professional athlete, a businessman with diabetes, or a small child with an iron deficiency, dietitians play an […]

Interview with a Lab Manager: Micah Simmons, UAB School of Medicine

Brief intro: Micah Simmons is a lab manager in the Department of Psychiatry and Behavioral Neurobiology at the University of Alabama at Birmingham School of Medicine. He works in the lab of Dr. James Meador-Woodruff, under whom he investigates the molecular mechanisms underlying schizophrenia.   When did you decide you wanted to become a lab […]

Organs Without a Home: The Fascinating World of 3-D Bioprinting

This past February, the Wakeforest Institute of Regenerative Medicine accomplished the most advanced feat of tissue regeneration to date: they created a human ear, and kept it alive attached to the backside of a mouse. The ear, exhibiting human-like vasculature and cartilage development, is a promising beginning to the quest to create customized organs. In […]
