Magnesium Overview Every organ in the body -- especially the heart, muscles, and kidneys -- needs the mineral magnesium. It also contributes to the makeup of teeth and bones. Most important, it activates enzymes, contributes to energy production, and helps regulate calcium levels, as well as copper, zinc, potassium, vitamin D, and other important nutrients in the body. You can get magnesium from many foods. Although you may not get enough magnesium from your diet, it’s rare to be truly deficient in magnesium. Symptoms of magnesium deficiency may include agitation and anxiety, restless leg syndrome (RLS), sleep disorders, irritability, nausea and vomiting, abnormal heart rhythms, low blood pressure, confusion, muscle spasm and weakness, hyperventilation, insomnia, poor nail growth, and even seizures. Uses Getting enough magnesium may enhance the effectiveness of conventional treatment for the following conditions: Asthma Depression Diabetes Fibromyalgia Noise related hearing loss High blood pressure Adult
City Form Lab | Urban Network Analysis Download Help Forum Source Press The City Form Lab has released a state-of-the-art toolbox for urban network analysis. As the first of its kind, the Centrality Tools this ArcGIS toolbox can be used to compute five types of graph analysis measures on spatial networks: Reach; Gravity; Betweenness; Closeness; and Straightness. Redundancy Redundancy Tools additionally calculate the Redundancy Index, Redundant Paths, and the Wayfinding Index. The tools incorporate three important features that make them particularly suited for spatial analysis on urban street networks. The tools are aimed at urban designers, architects, planners, geographers, and spatial analysts who are interested in studying the spatial configurations of cities, and their related social, economic, and environmental processes.

MIT Develops Ionic Wind Thrusters As An Efficient Alternative To Jet Engines Ion thruster photo from NASA A team from MIT is working on developing ionic wind thrusters as an energy-efficient, low-emission alternative to conventional propulsion technologies like jet engines. The new thrusters would use ionic energy, which is created when a current passes between two electrodes. If one electrode is thinner than the other, it creates an air current in the space between them – and if a substantial voltage is applied, the device could produce powerful thrust without the need for fuel or motors. Ionic wind thrusters have been discussed ever since the 1960s, but up till now they’ve been dismissed as impractical or suitable only for lightweight vehicles. Following a series of experiments, the MIT team announced that ionic thrusters could be more efficient than engines currently used in the aerospace industry. There is currently one thing blocking the future development of ionic engines – thrust density.
Magnesium and the Brain: The Original Chill Pill Magnesium is a vital nutrient that is often deficient in modern diets. Our ancient ancestors would have had a ready supply from organ meats, seafood, mineral water, and even swimming in the ocean, but modern soils can be depleted of minerals and magnesium is removed from water during routine municipal treatment. The current RDA for adults is between 320 and 420mg daily , and the average US intake is around 250mg daily. Does it matter if we are a little bit deficient? Well, magnesium plays an important role in biochemical reactions all over your body. That doesn't mean that magnesium is unimportant in the brain. Magnesium is an old home remedy for all that ails you, including "anxiety, apathy, depression , headaches, insecurity, irritability, restlessness, talkativeness, and sulkiness." Stress is the bad guy here, in addition to our woeful magnesium deficient diets. Let's look at Eby's case studies from his paper: Let's look at the mechanisms first.
DoppelLab | Sensor Data A mighty wind When a current passes between two electrodes — one thinner than the other — it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel. This phenomenon, called electrohydrodynamic thrust — or, more colloquially, “ionic wind” — was first identified in the 1960s. Since then, ionic wind has largely been limited to science-fair projects and basement experiments; hobbyists have posted hundreds of how-to videos on building “ionocrafts” — lightweight vehicles made of balsa wood, aluminum foil and wire — that lift off and hover with increased voltage. Despite this wealth of hobbyist information, there have been few rigorous studies of ionic wind as a viable propulsion system. Now researchers at MIT have run their own experiments and found that ionic thrusters may be a far more efficient source of propulsion than conventional jet engines.

Does Magnesium Work For Anxiety? Anxiety is not generally something you want to treat with prescription medication. It's not that prescription medications are bad necessarily – although there are several side effects and addiction risk that make them less than ideal. The problem is that they don’t actually cure the problem. Natural treatments are much more preferable. Their advantage is that they not only treat anxiety – they also give you an opportunity to relieve anxiety without medications someday in the future. They cause no dependency, no side effects, and using them doesn't impact your ability to learn valuable coping strategies. Herbal solutions are more common, but some nutrients may be beneficial for anxiety as well. Natural Treatments for Anxiety Prescription medications are unlikely to kill you, but they dull your ability to feel nervous, even in situations that call for it. Get started today by taking my 7 minute anxiety test. Magnesium – The Formerly Common Mineral Diet is rarely the only cause of anxiety.
Data from Digital Media Technologies (download as PDF >>) How can architects relate to digital media? The Mobile City keynote at the ‘Day of the Young Architect’: outcomes and further thoughts written by Michiel de Lange & Martijn de Waal Introducing the main questions What do developments in digital media have to do with architecture? We gladly accepted this challenge, since this very issue was one of the main reasons we founded The Mobile City two years ago. This report contains the main argument of our talk. In answering these questions, we make a strong plea for an attitude of ‘critical engagement’. Architecture and new media Now let us work out this argument in more detail. Yet we believe a new phase has ushered in. We propose that this new phase impels architecture to relate to digital media in a new way, beyond merely using them as instruments, to represent their spatial logic in design, or to design for virtual worlds. Ignore Why wouldn’t architects and planners simply ignore developments in the field of new media?
Magnesium: Why You Need It Magnesium (Mg) may be the most overlooked mineral. No one has yet popularized a simple way to remember it, in the way that we usually associate potassium with bananas, calcium with bone health, and sodium with blood pressure. But magnesium is an incredibly versatile and important nutrient that many doctors, nutritionists, and researchers believe is the single most important nutrient for human health. It is essential for over 300 different chemical reactions in the body, including maintaining your energy level, helping you relax, and sustaining the health of your heart and blood vessels. Unfortunately, in most of the developed world, magnesium deficiency is probably the most common nutritional deficiency. What is magnesium good for? One of its most common uses is for alleviating constipation; you may recognize it as the active ingredient in well-known over-the-counter laxative medicines. As with all minerals in foods, the mineral has to be present in the soil where the food is grown.
