Blasts, Helmets and Brain Injury

The Institute for Soldier Nanotechnologies at MIT together with the Defense and Veterans Brain Injury Center has released a study of blasts, helmets and brain injury. They set out to test a theory that military traumatic brain injury is made worse by the current helmet design.

Compared to the unhelmeted head, the head with helmet experienced slight mitigation of intracranial stresses. This suggests that the existing [Advanced Combat Helmet] ACH does not significantly contribute to mitigating blast effects, but does not worsen them either. By contrast, the helmet and face shield combination impeded direct transmission of stress waves to the face, resulting in a delay in the transmission of stresses to the intracranial cavity and lower intracranial stresses. This suggests a possible strategy for mitigating blast waves often associated with military concussion.

They designed and ran computer simulations, which concluded the opposite; a helmet does not make the blast effect worse but could be improved to reduce damage. The simulation found that the brain is exposed to blasts through the front of the skull due to the soft skin and holes (e.g. nose and eye sockets) — areas that offer the least protection. A face shield is therefore proposed.

The study is interesting because of evolving threats. Helmets have been studied for impact on a hard surface or for penetration by a sharp object. The rise in brain injuries led to a question about the suitability of existing helmets for the latest attack conditions.

Blast-induced traumatic brain injury is the most prevalent military injury in Iraq and Afghanistan, yet little is known about the mechanical effects of blasts on the human head, and still less is known about how personal protective equipment affects the brain’s response to blasts.

This study brought to mind Florence Nightingale’s “coxcomb” graph (now called a polar-area diagram). She illustrated her Notes on Matters Affecting the Health, Efficiency and Hospital Administration of the British Army in 1858 with this graphic showing cause of death in the Crimean War. Wounds (small red slices) caused only a small fraction of the overall body count. Diseases (big blue slices) were the biggest threat to life. The black slices denote an “other” category:

Her chart has been criticized for accuracy as well as style. A bar chart would be more contemporary but, in terms of this blast study on helmets and casualties, I have seen neither.

The Second Coming

by William Butler Yeats (1865-1939)

Turning and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart; the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.

Surely some revelation is at hand;
Surely the Second Coming is at hand.
The Second Coming! Hardly are those words out
When a vast image out of Spiritus Mundi
Troubles my sight: a waste of desert sand;
A shape with lion body and the head of a man,
A gaze blank and pitiless as the sun,
Is moving its slow thighs, while all about it
Wind shadows of the indignant desert birds.
The darkness drops again but now I know
That twenty centuries of stony sleep
Were vexed to nightmare by a rocking cradle,
And what rough beast, its hour come round at last,
Slouches towards Bethlehem to be born?

Interesting that this was written soon after the first World War had ended. I am tempted to research and see if I can find evidence of bias towards those who show a lack of conviction — ones who look before leaping.

The most famous line here “The best lack all conviction, while the worst are full of passionate intensity” is cited in a personal appeal by Jimmy Wales, Wikipedia’s founder, on the Dunning-Kruger effect.

The unskilled therefore suffer from illusory superiority, rating their own ability as above average, much higher than it actually is, while the highly skilled underrate their abilities, suffering from illusory inferiority. This leads to the situation in which less competent people rate their own ability higher than more competent people.

No conclusion is provided by Wales other than what the research shows on its own. He brings up various types and forms of bias but leaves out the role of historical events such as World War I.

Eleventh hour of the eleventh day of the eleventh month

Today marks Armistice Day, the 1918 surrender of Germany that ended hostility on the Western Front in World War I.

It also is known as Veteran’s Day in the US, thanks to sentiment from Kansas, as I have written before.

Poppies are used for remembrance in reference to one of the most heavily contested areas of Europe, Flanders, which sits between French, German and British control. The flowers grew all around the battlefields and expanding cemeteries of Belgium.

A poem called “In Flanders Fields” was written by Canadian Colonel John McCrae while fighting there and published in 1915:

In Flanders fields the poppies blow
      Between the crosses, row on row,
   That mark our place; and in the sky
   The larks, still bravely singing, fly
Scarce heard amid the guns below.

We are the Dead. Short days ago
We lived, felt dawn, saw sunset glow,
   Loved and were loved, and now we lie,
         In Flanders fields.

Take up our quarrel with the foe:
To you from failing hands we throw
   The torch; be yours to hold it high.
   If ye break faith with us who die
We shall not sleep, though poppies grow
         In Flanders fields.

The reference to crosses is not universal for more reasons than one might expect. Today the German news points out that some of the dead are treated differently from the other casualties in Flanders.

The Langemark cemetery is the final resting place of 44,294 German soldiers. More than half of them are buried in one mass grave, the Kameraden Grab, their names etched on large dark plaques running alongside the site.

[Andre de Bruin, a World War I guide and founder of Over The Top Tours] points to rows of gravestones that lie flat on ground, explaining: “Belgium imposed very strict restrictions on German memorials. Headstones were not allowed to stand, not like those of the Commonwealth soldiers and there were many other rules that applied only to Germans.”

There were hundreds of burial sites of German soldiers after 1918 but in the 1950s, Belgium ordered that the bodies be regrouped in no more than four sites, of which Langemark is one.

“It was probably done out of hatred for what happened, especially during World War II when Belgium was occupied. They even forbade the use of crosses above the headstones,” de Bruin said.

Breaking the Law With High Fructose Corn Syrup

The Public Health Advocacy Institute has dropped a wet blanket over the high fructose corn syrup lobby. The lobby has claimed sugar is always sugar, no matter what, based on measured levels of fructose. To prove their point using propaganda they have started to pressure the government to allow corn syrup to be hidden with the label corn sugar.

While they play games with the names, actual fructose measurements are in and it does not look good for high fructose corn syrup. It turns out that it has…high fructose.

A report on October 27th from the PHAI is thus titled: Discovery of Elevated Fructose Levels in Popular Soft Drinks Raises Important Legal Questions for Regulators and Consumers

Laboratory testing revealed that bottled full-calorie Pepsi, Coca-Cola and Sprite had fructose estimates of 64-65%, well in excess of the upper-level of 55% fructose generally recognized as safe by the Food and Drug Administration

These levels not only put them in excess of safe levels, defined by others, but also at odds with their own claims to safety.

…the representation that HFCS is “compositionally equivalent” to table sugar could amount to false and misleading advertising requiring action by the Federal Trade Commission and State Attorneys General.

Fructose was isolated and extracted from corn in America during 1970s after President Nixon’s economic advisers demanded that payments for corn surplus should be put to some kind of use. Leaders of the country at that time balked at the idea of paying farmers to grow something and then do nothing with it, so they set about to manufacture demand. The very recent origin of high fructose corn syrup was thus driven by an artificial (US Patent 3,689,362 by Yoshiyuki Takasaki in 1972) urgency related to farm politics, as I have discussed before.

I could also point out the political importance of high fructose corn syrup comes from an even older issue of national concern. The reason corn syrup has been made cheaper to use in processed foods than sugar is due to import quotas that restrict America’s supply of sugar.

Before artificial corn sweeteners were made in America the US Marines were called into action to invade the state of Hawaii in 1894 and overthrow the Queen. This was to ensure access to sugar. American plantation owners feared they would lose their land to the Queen if she maintained power. They formed a “Committee of Safety to overthrow the Kingdom” and found a sympathetic ear in the US Secretary of State, James Blaine. He had suggested in 1881 that the US would be better off invading Cuba, another rich source of sugar, than to let it sit in the hands of a European power.

The sugar of Hawaii is not enough to meet demand today. This makes me wonder if Blaine had realized the safety risk present today from high fructose corn syrup in America, would he have pressed even more to annex Cuba? Alas, Cuba became independent and America continues to try and find ways to dispose of its corn surplus.
