Metabolic syndrome, a term used to describe a combination of risk factors that often lead to heart disease and type 2 diabetes, seems to be linked to lower blood flow to the brain, according to research by the University of Wisconsin School of Medicine and Public Health.

Nuclides!

post from Physics Buzz on 18 July 2012 11:16:40 AM. © Physics Buzz

When I was taking high school Chemistry, I made it a point to make sure that I knew the periodic table. Mr. Clark (my instructor) made sure to impress this upon me. ?Learn the periodic table and you can pass my course!? Well, I did. I learned and mastered the periodic table to the extent that I HAD TO LEARN ANOTHER GOSH DARN TABLE IN COLLEGE! You can imagine the disdain I had, to learn (from a Nuclear Chemistry course) that there was a Chart of the Nuclides. I smiled and buckled down to master this chart as well. I am glad that I did, it was still based upon the periodic table. This was my introduction into applied particle physics.

What is the Chart of the Nuclides? In simpler terms this chart is essentially a graph that one axis represents the number of neutrons and the other axis represents the number of protons in an atomic nucleus. The nuclide chart organizes isotopes along the X axis by their numbers of neutrons and along the Y axis by their numbers of protons, out to the limits of the neutron and proton drip lines (boundaries for nuclear particle-stability).

Each point plotted on the graph represents the nuclide of a real or hypothetical chemical element. The ordering of nuclides can garner more insight into the characteristics of isotopes than the periodic table of the elements that displays only elements instead of each of their isotopes.

In addition, the chart of the nuclides is similar to a map of the nuclear or radioactive behavior of nuclides, as it distinguishes the isotopes of an element. It contrasts with a periodic table, because only the chemical behavior of the element is shown, since isotopes of the same element do not differ chemically.

So just when you think that the study of particles ends with the periodic table of the elements, don?t rest on that theory. There is another chart that will stump you. With time and dedication, this chart can be conquered! Take a look and discover more about the chart of the nuclides by clicking on the links below.

Gone Swimming

post from CR4 - Recent Blog Entries on 18 July 2012 11:03:00 AM. © CR4 - Recent Blog Entries

The fastest way to cool off in the summer time is to go for a swim. And while you're lounging on your neon pink floaty, you're probably not thinking about the acidy level of the pool (then again, this is an engineering community), but it is a critical component of the health and safety of you and yo

On July 1, 2012 The Australian Government introduced a "Tax on Carbon". The tax covers the majority of the economy with few exceptions.The price established by the government is $A23/ton. This price is fixed with a 5% increase each year for the first three years and then the tax will convert t

TED: Baba Shiv: Sometimes it's good to give up
the driver's seat - Baba Shiv (2012)

post from TEDTalks (video) on 18 July 2012 10:59:35 AM. © TEDTalks (video)

Over the years, research has shown a counterintuitive fact about human nature: That sometimes, having too much choice makes us less happy. This may even be true when it comes to medical treatment. Baba Shiv shares a fascinating study that measures why choice opens the door to doubt, and suggests that ceding control -- especially on life-or-death decisions -- may be the best thing for us.

GMs Far-Out 59s: When Imagination Ran Rampant

Ah, the late 1950s. GM designers were on the verge of revolting against Harley Earl, the 1959 designs looked to continue the 1958 designs' emphasis on chrome and blockiness, and in the midst of it all, GM's designers were suddenly given nearly unlimited free reign to design the future. Micha

Gliding over the edge

post from British Oceanographic Data Centre (BODC) on 18 July 2012 09:08:00 AM. © British Oceanographic Data Centre (BODC)

Mark Hebden, a British Oceanogarphic Data Centre (BODC) Data Scientist, recently returned from RRS Discovery cruise D376. This is the first cruise for Fluxes Across Sloping Topography of the North East Atlantic (FASTNEt). FASTNEt is a four-year initiative that aims to improve our understanding of the physical and biogeochemical exchange taking place across continental shelf edge margins. From the start, BODC have been working with FASTNEt scientists to ensure the provision of adequate data management.
Following a successful mission the scientists onboard D376 recover their glider. ©
Shelf edge regions mark the gateway between the world's deep oceans and its shallower coastal seas. They link terrestrial, atmospheric and oceanic carbon pools. Shelf margin processes have a direct influence on near-shore productivity (and consequently fisheries) as well as affecting global climate.Traditionally, research cruises have offered a brief opportunity to collect data; we still have only snapshots of marine environments. D376 was notable for its ambitious data collection regime. The combination of traditional sampling techniques coupled with novel autonomous technologies represents a new era in observational oceanography.D376 deployed four gliders at the shelf edge. Gliders are autonomous vehicles that use small changes in their buoyancy to descend and ascend through the water column. Three of these gliders will be gathering data on and off the Celtic Sea shelf until autumn 2012. Between dives, scientific sensors will collect near-real-time data and transmit them via satellite back to shore.Data Scientist cruise participation strengthens project relationships and increases familiarity with data streams. This has a direct influence on the efficiency of data assimilation to the data centre. While at sea, Mark was responsible for compiling accurate and complete metadata ? essential information about data.The cruise also marked another significant milestone, one which nods firmly to the past. With the scientific objectives completed, RRS Discovery set sail for port, arriving on the eve of the 50th anniversary of her launch. Discovery will be taken out of service later this year. Her replacement will take over in 2013.Discovery has played a central role in marine research, from charting the ocean floor, contributing to climate change research and discovering marine species. An important and significant legacy of data, for use long into the future, remains as a fitting testament to 50 years of research.
