Mammal Radiators

Thursday, September 13th, 2012

Black bears are extremely well-insulated animals, with a thick fur coat over a thick layer of fat. This keeps them quite warm in the winter:

But once spring arrives and temperatures rise, these same bears face a greater risk of overheating than of hypothermia. How do they dump heat without changing insulation layers?

Heller and Grahn discovered that bears and, in fact, nearly all mammals have built-in radiators: hairless areas of the body that feature extensive networks of veins very close to the surface of the skin.

Rabbits have them in their ears, rats have them in their tails, dogs have them in their tongues. Heat transfer with the environment overwhelmingly occurs on these relatively small patches of skin. When you look at a thermal scan of a bear, the animal is mostly indistinguishable from the background. But the pads of the bear’s feet and the tip of the nose look like they’re on fire.

These networks of veins, known as AVAs (arteriovenous anastomoses) seem exclusively devoted to rapid temperature management. They don’t supply nutrition to the skin, and they have highly variable blood flow, ranging from negligible in cold weather to as much as 60 percent of total cardiac output during hot weather or exercise.

In humans, AVAs show up in the face, feet, and hands — which means that a refrigerated glove can cool humans quickly:

The newest version of the device is a rigid plastic mitt, attached by a hose to what looks like a portable cooler. When Grahn sticks his hand in the airtight glove, the device creates a slight vacuum. The veins in the palm expand, drawing blood into the AVAs, where it is rapidly cooled by water circulating through the glove’s plastic lining.

The method is more convenient than, say, full-body submersion in ice water, and avoids the pitfalls of other rapid palm-cooling strategies. Because blood flow to the AVAs can be nearly shut off in cold weather, making the hand too cold will have almost no effect on core temperature. Cooling, Grahn says, is therefore a delicate balance.

“You have to stay above the local vasoconstriction threshold,” said Grahn. “And what do you get if you go under? You get a cold hand.”

Even in prototype form, the researchers’ device proved enormously efficient at altering body temperature. The glove’s early successes were actually in increasing the core temperature of surgery patients recovering from anesthesia.

“We built a silly device, took it over to the recovery room and, lo and behold, it worked beyond our wildest imaginations,” Heller explained. “Whereas it was taking them hours to re-warm patients coming into the recovery room, we were doing it in eight, nine minutes.”

Overheating is a problem for athletes — and not just marathon-runners:

But the glove’s effects on athletic performance didn’t become apparent until the researchers began using the glove to cool a member of the lab — the confessed “gym rat” and frequent coauthor Vinh Cao — between sets of pull-ups. The glove seemed to nearly erase his muscle fatigue; after multiple rounds, cooling allowed him to do just as many pull-ups as he did the first time around. So the researchers started cooling him after every other set of pull-ups.

“Then in the next six weeks he went from doing 180 pull-ups total to over 620,” said Heller. “That was a rate of physical performance improvement that was just unprecedented.”

The researchers applied the cooling method to other types of exercise — bench press, running, cycling. In every case, rates of gain in recovery were dramatic, without any evidence of the body being damaged by overwork — hence the “better than steroids” claim. Versions of the glove have since been adopted by the Stanford football and track and field teams, as well as other college athletics programs, the San Francisco 49ers, the Oakland Raiders and Manchester United soccer club.

When I studied exercise physiology years ago, fatigue was described through the three energy systems: ATP depletion, or lactic acid accumulation, or glycogen depletion, etc. This new research suggests that temperature is the primary limiting factor for performance:

In 2009, it was discovered that muscle pyruvate kinase, or MPK, an enzyme that muscles need in order to generate chemical energy, was highly temperature-sensitive. At normal body temperature, the enzyme is active — but as temperatures rise, some of the enzyme begins to deform into the inactive state. By the time muscle temperatures near 104 degrees Fahrenheit, MPK activity completely shuts down.

So, cooling should improve performance, but it shouldn’t necessarily improve training, if you want to adapt to overheating.

Raspberry Pi

Thursday, September 13th, 2012

The Raspberry Pi folks describe their product as an ARM GNU/Linux box for $25, so the natural reaction is to ask, can I make a supercomputer out of these things?

The answer is yes — and you can tie the whole thing together with Lego:

The racking was built using Lego with a design developed by Simon and James, who has also been testing the Raspberry Pi by programming it using free computer programming software Python and Scratch over the summer. The machine, named “Iridis-Pi” after the University’s Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet. The whole system cost under £2,500 (excluding switches) and has a total of 64 processors and 1Tb of memory (16Gb SD cards for each Raspberry Pi). Professor Cox uses the free plug-in ‘Python Tools for Visual Studio’ to develop code for the Raspberry Pi.

Professor Cox adds: “The first test we ran, well, obviously we calculated Pi on the Raspberry Pi using MPI, which is a well-known first test for any new supercomputer.”

Digital Textbooks

Thursday, September 13th, 2012

Media companies like Discovery — the company behind the Discovery Channel — are pushing into education, because they see in digital textbooks a growth opportunity too good to pass up:

Conventional textbooks for kindergarten through 12th grade are a $3 billion business in the United States, according to the Association of American Publishers, with an additional $4 billion spent on teacher guides, testing resources and reference materials. And almost all that printed material, educators say, will eventually be replaced by digital versions.

And then there’s Disney:

It is building a chain of language schools in China big enough to enroll more than 150,000 children annually. The schools, which weave Disney characters into the curriculum, are not going to move the profit needle at a company with $41 billion in annual revenue. But they could play a vital role in creating a consumer base as Disney builds a $4.4 billion theme park and resort in Shanghai.

This move into education has failed before:

Discovery in 2006 promoted Cosmeo, an Internet-based service that offered children videos and other tools to help them with their homework; a year later, Discovery decided to stop marketing the product, which cost $99 a year, and laid off much of its staff. (Why pay for help when you can search Google at no cost?)

In 2007, Disney introduced a new position — senior vice president for learning — with the goal of moving into the North American education businesses. None of the company’s major efforts got off the ground, and Disney eventually pulled the plug, in part because it decided technology was changing the sector too rapidly.

Geography of the Middle East

Wednesday, September 12th, 2012

Robert Kaplan prefers to emphasize the geography of the Middle East, rather than its various ideologies:

As advocates continue to urge intervention in Syria, it is useful to recall that the modern state of that name is a geographic ghost of its post-Ottoman self, which included what are now Lebanon, Jordan and Israel. Even that larger entity was less a well-defined place than a vague geographical expression. Still, the truncated modern state of Syria contains all the communal divides of the old Ottoman region. Its ethno-religious makeup since independence in 1944 — Alawites in the northwest, Sunnis in the central corridor, Druze in the south — make it an Arab Yugoslavia in the making. These divisions are what long made Syria the throbbing heart of pan-Arabism and the ultimate rejectionist state vis-à-vis Israel. Only by appealing to a radical Arab identity beyond the call of sect could Syria assuage the forces that have always threatened to tear the country apart.

But this does not mean that Syria must now descend into anarchy, for geography has many stories to tell. Syria and Iraq both have deep roots in specific agricultural terrains that hark back millennia, making them less artificial than is supposed. Syria could yet survive as a 21st-century equivalent of early 20th-century Beirut, Alexandria and Smyrna: a Levantine world of multiple identities united by commerce and anchored to the Mediterranean. Ethnic divisions based on geography can be overcome, but only if we first recognize how formidable they are.

Finally, there is the problem of Iran, which has vexed American policy makers since the Islamic Revolution of 1979. The U.S. tends to see Iranian power in ideological terms, but a good deal can be learned from the country’s formidable geographic advantages.

The state of Iran conforms with the Iranian plateau, an impregnable natural fortress that straddles both oil-producing regions of the Middle East: the Persian Gulf and the Caspian Sea. Moreover, from the western side of the Iranian plateau, all roads are open to Iraq down below. And from the Iranian plateau’s eastern and northeastern sides, all roads are open to Central Asia, where Iran is building roads and pipelines to several former Soviet republics.

Geography puts Iran in a favored position to dominate both Iraq and western Afghanistan, which it does nicely at the moment. Iran’s coastline in the Persian Gulf’s Strait of Hormuz is a vast 1,356 nautical miles long, with inlets perfect for hiding swarms of small suicide-attack boats. But for the presence of the U.S. Navy, this would allow Iran to rule the Persian Gulf. Iran also has 300 miles of Arabian Sea frontage, making it vital for Central Asia’s future access to international waters. India has been helping Iran develop the port of Chah Bahar in Iranian Baluchistan, which will one day be linked to the gas and oil fields of the Caspian basin.

Iran is the geographic pivot state of the Greater Middle East, and it is essential for the United States to reach an accommodation with it. The regime of the ayatollahs descends from the Medes, Parthians, Achaemenids and Sassanids of yore — Iranian peoples all — whose sphere of influence from the Syrian desert to the Indian subcontinent was built on a clearly defined geography.

There is one crucial difference, however: Iran’s current quasi-empire is built on fear and suffocating clerical rule, both of which greatly limit its appeal and point to its eventual downfall. Under this regime, the Technicolor has disappeared from the Iranian landscape, replaced by a grainy black-and-white. The West should be less concerned with stopping Iran’s nuclear program than with developing a grand strategy for transforming the regime.

Libya

Wednesday, September 12th, 2012

Sean Smith, a Foreign Service Information Management Officer assigned to the American consulate in Benghazi, Libya played EVE Online, the politically interesting computer game, as a member of the so-called Goonswarm, and on Tuesday he answered the director of his gaming guild with this:

“Assuming we don’t die tonight. We saw one of our ‘police’ that guard the compound taking pictures.” The consulate was under siege, and within hours, a mob would attack, killing Smith along with three others, including the U.S. ambassador.

In his professional and personal life, Smith was a husband and father of two, and a 10-year veteran of the Foreign Service who had served in Baghdad, Pretoria, Montreal and The Hague. But when gaming with EVE Online guild Goonswarm, he was a popular figure known as “Vile Rat,” and alternately as “Vilerat” while volunteering as a moderator at the internet community Something Awful. Smith’s death was confirmed on Wednesday morning by the State Department and reported widely in the news media.

A Marine FAST team is on its way.

What No Easy Day Reveals About Navy SEAL Gear

Wednesday, September 12th, 2012

Popular Mechanics focuses on what No Easy Day reveals about Navy SEAL gear:

Knives and tools: Bissonnette says that a Gerber multitool, which includes a knife blade, screwdriver, scissors, and can opener, was provided to each member of Seal Team Six. So was a fixed-blade knife.

Weapons: According to the book, SEALs like Bissonnette get a “standard issue” Sig Sauer P226 (he also had an HK 45C), though he says the weapon he used on a daily basis was the HK 416 with a ten inch barrel and suppressor. Owens went on some missions with a MP7 submachine gun, but says it wasn’t as powerful as the HK 416. His other guns included another HK 416, this one with a fourteen-inch barrel, which he preferred for long-range shots. SEALS also carry what they call the “pirate gun”: The Vietnam-era M79 grenade launcher, nicknamed for its odd resemblance to a blunderbuss.

Breaching gear: SEAL Team 6 members like Own would typically carry explosive breaching charges, bolt cutters, and even a sledge hammer, used for gaining entry through locked doors and gates.

Combat Assault Dog, or CAD: Cairo, the Belgian Malinois who went on the Osama bin Laden mission, brought national fame to the SEAL Team Six’s use of assault dogs. The “hair missiles,” as one of Bissonnette’s colleagues describe the dogs, can detect bombs and track and attack people. Owen credits the CAD with saving his life on one mission in Afghanistan whenthe dog found an insurgent hiding in a ditch, ready to attack, after his team thought it had cleared the area around them.

Night-vision goggles: Bissonnette mentions the top-of-the-line night-vision equipment issued to SEAL Team Six. Members carry four-tube night vision goggles rather than the standard two-tube ones, which have a larger field of view. They cost about $65,000 per pair, the author says.

Uniform and body armor: On the Abbottabad raid, Bissonnette says he wore a Crye Precision Desert Digital Combat Uniform. “Designed like a long-sleeved shirt and cargo pants, the uniform had ten pockets, each with a specific purpose,” he writes. The uniform wicks away sweat, but Bissonnette also made his own modification by cutting off the sleeves. (For some servicemen this would be a major no-no, but SEAL Team Six members aren’t required to wear standard-issue combat clothing). Members also get a vest with room for ballistic plates, though Bissonnette mentions leaving the plates behind on one mission to save weight. As for shoes, Owen opted for Salomon Quest boots to protect his ankles.

Sensitive Site Exploitation Kit: With SEALs increasingly called upon to help do detective work by collecting evidence, Owen traveled with rubber gloves, a digital camera, and a DNA collection kit. SEAL Team Tix took DNA swabs from Osama bin Laden at the compound in Abbottabad, in case the body couldn’t be recovered.

Ambien: Long flights on C-17 transport aircraft often mean popping the popular sleeping pill. Bissonnette writes about taking Ambien to sleep several times in the book, and in particular on the final night before the Osama bin Laden raid.

Miscellaneous gear: Among the other gear Bissonnette talks about using are “bone phones,” which are essentially communication devices that allow the user to hear through bone conduction technology. He also carried infrared chemical lights to mark specific spots, an extendable ladder, a Princeton Tech charge light, a Daniel Winkler fixed blade knife, assault gloves, leather mitts, batteries, energy gel, and two power bars. On the Osama bin Laden raid, he carried one more thing: $200, in case everything went wrong.

Rooftop Villas

Wednesday, September 12th, 2012

Four houses were built on the rooftop of the Jiutian International Square, a shopping mall in Zhuzhou, Hunan province:

The buildings, which have electricity and water pipes already installed, will be offices for the shopping mall developer’s 160 real estate management employees, said Li Li from the Zhuzhou city planning bureau.

China’s Geography

Tuesday, September 11th, 2012

Robert Kaplan looks at China through the lens of geography:

China is big in one sense: its population, its commercial and energy enterprises and its economy as a whole are creating zones of influence in contiguous parts of the Russian Far East, Central Asia and Southeast Asia. But Chinese leaders themselves often see their country as relatively small and fragile: within its borders are sizable minority populations of Tibetans in the southwest, Uighur Turks in the west and ethnic-Mongolians in the north.

It is these minority areas—high plateaus virtually encircling the ethnic core of Han Chinese—where much of China’s fresh water, hydrocarbons and other natural resources come from. The West blithely tells the Chinese leadership to liberalize their political system. But the Chinese leaders know their own geography. They know that democratization in even the mildest form threatens to unleash ethnic fury.

Because ethnic minorities in China live in specific regions, the prospect of China breaking apart is not out of the question. That is why Beijing pours Han immigrants into the big cities of Tibet and western Xinjiang province, even as it hands out small doses of autonomy to the periphery and continues to artificially stimulate the economies there. These policies may be unsustainable, but they emanate ultimately from a vast and varied continental geography, which extends into the Western Pacific, where China finds itself boxed in by a chain of U. S. naval allies from Japan to Australia. It is for reasons of geographic realpolitik that China is determined to incorporate Taiwan into its dominion.

The NFL Moves Back Into the Dorms

Tuesday, September 11th, 2012

Former Baylor quarterback Robert Griffin made his NFL debut with the Washington Redskins Sunday, but he continued to lead a college-style offense:

Last season, the Redskins ran out of the shotgun 33% of the time — just shy of the 41% average for all NFL teams. On Sunday, however, they ran it on 20 of the first 23 offensive snaps, something you hardly ever see outside college campuses.

On just the third snap, one play after running a shotgun option, Shanahan’s Baylorskins ran the pistol. This formation, in which Griffin started from the shotgun with the running back lined up behind him, was a clear case of pandering to Griffin’s skills. Montgomery noted that this exact play was “worked hard” early in Griffin’s college career. After taking the snap, Griffin faked a handoff then threw a quick dart pass to receiver Pierre Garcon who was split wide, for a 12-yard gain.

At the start of the second quarter, Griffin lined up in shotgun with a running back to his right again—but with another one directly behind him (see photo). This time, after faking the handoff to running back Alfred Morris, Griffin rolled out to his left, eluded the rushing defensive line and threw the ball across the field for a 26-yard strike to tight end Fred Davis.

Griffin’s statistics from Sunday don’t look like NFL statistics: According to researchers at Pro Football Focus, Griffin threw 13 of his 25 passes within nine yards of the line of scrimmage and threw more than 20 yards on just two plays. In the same game, Saints quarterback Drew Brees, a more-traditional NFL pocket passer, threw 11 passes longer than 20 yards.

After the game, Redskins players and coaches spoke about how important it was that the Saints didn’t know what was coming. Asked about this, Saints interim coach Aaron Kromer said his team wasn’t surprised to see Griffin running bootlegs, quarterback runs and “read options,” they just couldn’t stop them.

The big question for the copycat NFL is whether Griffin’s success will trigger a Pavlovian response among other coaches.

Criminals and the Guns They Carry

Tuesday, September 11th, 2012

As a police training officer, Greg Ellifritz has access to all the guns his department seizes from criminals, so he knows which guns criminals carry — or, at least, which guns the few criminals in his suburban Midwest community carry:

As I stated above, this study contains the details the most recent 85 firearms taken from criminals by my agency. Of those 85 guns:

  • 67 handguns
    • 13 revolvers
    • 52 semi-automatic pistols
    • 1 Derringer
    • 1 illegally-converted fully automatic machine pistol
  • 11 rifles
    • 4 bolt-actions
    • 7 semi-automatic rifles
  • 7 shotguns
    • 4 pump-actions
    • 3 single-shots or double-barrels

We had a wide variety of firearms manufacturers included in the database. Companies that represented the most seized guns were:

  • Ruger – 9
  • Smith and Wesson – 6
  • Glock – 5
  • Hi Point – 5
  • Beretta – 4
  • Lorcin – 4
  • Remington – 4
  • Raven – 3
  • Jennings – 3
  • IntraTec – 3
  • Norinco – 3

Nine of the 85 weapons were completely broken and unable to function. 17 more of the guns had limited functionality because of frequent (at least 1 in the first 3 rounds I fired) malfunctions; 9 guns lack of magazines; 5 guns other problems like incorrect magazines, and internal parts breakage that lead to inconsistent firing ability.

[...]

Previous research conducted by the Bureau of Justice Statistics tells us that in all criminal victimizations with firearms; only 11 percent of the victims were shot or shot at. When criminal attacks with all weapons (knives, clubs, etc.) are included, less than one percent of armed criminal victimizations resulted in a gunshot wound. These statistics have always been puzzling to me. Why aren’t more people getting shot by criminals?

Now I know the answer. The criminals’ weapons won’t fire! Let’s break down the numbers again: Out of 85 weapons seized:

  • 24 are not loaded
  • 2 are not loaded with the correct ammunition
  • 9 are completely broken

Geography Strikes Back

Monday, September 10th, 2012

If you want to know what Russia, China or Iran will do next, don’t read their newspapers or ask what our spies have dug up, Robert Kaplan reiterates. Instead, look at a map:

Why, for example, are headlines screaming about the islands of the South China Sea? As the Pacific antechamber to the Indian Ocean, this sea connects the energy-rich Middle East and the emerging middle-class fleshpots of East Asia. It is also thought to contain significant stores of hydrocarbons. China thinks of the South China Sea much as the U.S. thinks of the Caribbean: as a blue-water extension of its mainland. Vietnam and the Philippines also abut this crucial body of water, which is why we are seeing maritime brinkmanship on all sides. It is a battle not of ideas but of physical space. The same can be said of the continuing dispute between Japan and Russia over the South Kuril Islands.

Why does President Vladimir Putin covet buffer zones in Eastern Europe and the Caucasus, just as the czars and commissars did before him? Because Russia still constitutes a vast, continental space that is unprotected by mountains and rivers. Putin’s neo-imperialism is the expression of a deep geographical insecurity.

Or consider the decade since 9/11, which can’t be understood apart from the mountains and deserts of Afghanistan and Iraq. The mountains of the Hindu Kush separate northern Afghanistan, populated by Tajiks and Uzbeks, from southern and eastern Afghanistan, populated by Pushtuns. The Taliban are Sunni extremists like al Qaeda, to whom they gave refuge in the days before 9/11, but more than that, they are a Pushtun national movement, a product of Afghanistan’s harsh geographic divide.

Moving eastward, we descend from Afghanistan’s high tableland to Pakistan’s steamy Indus River Valley. But the change of terrain is so gradual that, rather than being effectively separated by an international border, Afghanistan and Pakistan comprise the same Indo-Islamic world. From a geographical view, it seems naive to think that American diplomacy or military activity alone could divide these long-interconnected lands into two well-functioning states.

As for Iraq, ever since antiquity, the mountainous north and the riverine south and center have usually been in pitched battle. It started in the ancient world with conflict among Sumerians, Akkadians and Assyrians. Today the antagonists are Shiites, Sunnis, and Kurds. The names of the groups have changed but not the cartography of war.

Four Riders of the Modern Apocalypse

Monday, September 10th, 2012

The four riders of the modern apocalypse are chemicals (DDT, CFCs, acid rain), diseases (bird flu, swine flu, SARS, AIDS, Ebola, mad cow disease), people (population, famine), and resources (oil, metals).  Matt Ridley discusses DDT first:

Silent Spring, published 50 years ago this year, was instrumental in the emergence of modern environmentalism. “Without this book, the environmental movement might have been long delayed or never have developed at all,” Al Gore wrote in his introduction to the 1994 edition. Carson’s main theme was that the use of synthetic pesticides — DDT in particular — was causing not only a massacre of wildlife but an epidemic of cancer in human beings. One of her chief inspirations and sources for the book was Wilhelm Hueper, the first director of the environmental arm of the National Cancer Institute. So obsessed was Hueper with his notion that pesticides and other synthetic chemicals were causing cancers (and that industry was covering this up) that he strenuously opposed the suggestion that tobacco-smoking take any blame. Hueper wrote in a 1955 paper called “Lung Cancers and Their Causes,” published in CA: A Cancer Journal for Clinicians, “Industrial or industry-related atmospheric pollutants are to a great part responsible for the causation of lung cancer … cigarette smoking is not a major factor in the causation of lung cancer.”

In fact, of course, the link between smoking and lung cancer was found to be ironclad. But the link between modern chemicals and cancer is sketchy at best. Even DDT, which clearly does pose health risks to those unsafely exposed, has never been definitively linked to cancer. In general, cancer incidence and death rates, when corrected for the average age of the population, have been falling now for 20 years.

In the 1980s it was acid rain’s turn to be the source of apocalyptic forecasts:

In this case it was nature in the form of forests and lakes that would bear the brunt of human pollution. The issue caught fire in Germany, where a cover story in the news magazine Der Spiegel in November 1981 screamed: “THE FOREST DIES.” Not to be outdone, Stern magazine declared that a third of Germany’s forests were already dead or dying. Bernhard Ulrich, a soil scientist at the University of Göttingen, said it was already too late for the country’s forests: “They cannot be saved.” Forest death, or waldsterben, became a huge story across Europe. “The forests and lakes are dying. Already the damage may be irreversible,” journalist Fred Pearce wrote in New Scientist in 1982. It was much the same in North America: Half of all US lakes were said to be becoming dangerously acidified, and forests from Virginia to central Canada were thought to be suffering mass die-offs of trees.

Conventional wisdom has it that this fate was averted by prompt legislative action to reduce sulphur dioxide emissions from power plants. That account is largely false. There was no net loss of forest in the 1980s to reverse. In the US, a 10-year government-sponsored study involving some 700 scientists and costing about $500 million reported in 1990 that “there is no evidence of a general or unusual decline of forests in the United States and Canada due to acid rain” and “there is no case of forest decline in which acidic deposition is known to be a predominant cause.” In Germany, Heinrich Spiecker, director of the Institute for Forest Growth, was commissioned by a Finnish forestry organization to assess the health of European forests. He concluded that they were growing faster and healthier than ever and had been improving throughout the 1980s. “Since we began measuring the forest more than 100 years ago, there’s never been a higher volume of wood … than there is now,” Spiecker said. (Ironically, one of the chief ingredients of acid rain — nitrogen oxide — breaks down naturally to become nitrate, a fertilizer for trees.) As for lakes, it turned out that their rising acidity was likely caused more by reforestation than by acid rain; one study suggested that the correlation between acidity in rainwater and the pH in the lakes was very low. The story of acid rain is not of catastrophe averted but of a minor environmental nuisance somewhat abated.

Pallets

Sunday, September 9th, 2012

The single most important object in the global economy may be the humble pallet:

For an invisible object, they are everywhere: There are said to be billions circulating through global supply chain (2 billion in the United States alone). Some 80 percent of all U.S. commerce is carried on pallets. So widespread is their use that they account for, according to one estimate, more than 46 percent of total U.S. hardwood lumber production.

Companies like Ikea have literally designed products around pallets: Its “Bang” mug, notes Colin White in his book Strategic Management, has had three redesigns, each done not for aesthetics but to ensure that more mugs would fit on a pallet (not to mention in a customer’s cupboard). After the changes, it was possible to fit 2,204 mugs on a pallet, rather than the original 864, which created a 60 percent reduction in shipping costs. There is a whole science of “pallet cube optimization,” a kind of Tetris for packaging; and an associated engineering, filled with analyses of “pallet overhang” (stacking cartons so they hang over the edge of the pallet, resulting in losses of carton strength) and efforts to reduce “pallet gaps” (too much spacing between deckboards). The “pallet loading problem,”—or the question of how to fit the most boxes onto a single pallet—is a common operations research thought exercise.

Pallet history is both humble and dramatic. As Pallet Enterprise (“For 30 years the leading pallet and sawmill magazine”) recounts, pallets grew out of simple wooden “skids”, which had been used to help transport goods from shore to ship and were, essentially, pallets without a bottom set of boards, hand-loaded by longshoremen and then, typically, hoisted by winch into a ship’s cargo hold. Both skids and pallets allowed shippers to “unitize” goods, with clear efficiency benefits: “According to an article in a 1931 railway trade magazine, three days were required to unload a boxcar containing 13,000 cases of unpalletized canned goods. When the same amount of goods was loaded into the boxcar on pallets or skids, the identical task took only four hours.”

As USDA Forest Service researchers Gilbert P. Dempsey and David G. Martens noted in a conference paper, two factors led to the real rise of the pallet. The first was the 1937 invention of gas-powered forklift trucks, which “allowed goods to be moved, stacked, and stored with extraordinary speed and versatility.”

The second factor in the rise of the pallet was World War II. Logistics—the “Big ‘L’,” as one history puts it—is the secret story behind any successful military campaign, and pallets played a large role in the extraordinary supply efforts in the world’s first truly global war. As one historian, quoted by Rick Le Blanc in Pallet Enterprise, notes, “the use of the forklift trucks and pallets was the most significant and revolutionary storage development of the war.” Tens of millions of pallets were employed—particularly in the Pacific campaigns, with their elongated supply lines. Looking to improve turnaround times for materials handling, a Navy Supply Corps officer named Norman Cahners—who would go on to found the publishing giant of the same name—invented the “four-way pallet.” This relatively minor refinement, which featured notches cut in the side so that forklifts could pick up pallets from any direction, doubled material-handling productivity per man. If there’s a Silver Star for optimization, it belongs to Cahners.

As a sort of peace dividend, at war’s end the U.S. military left the Australian government with not only many forklifts and cranes, but about 60,000 pallets. To handle these resources, the Australian government created the Commonwealth Handling Equipment Pool, and the company eventually spawned a modern pallet powerhouse, CHEP USA, which now controls about 90 percent of the “pooled” pallet market in the United States.  Pooled pallets are rented from one company that takes care of delivering and retrieving them; the alternative is a “one-way” pallet, essentially a disposable item that is scrapped, recycled or reused when its initial journey is done. You can identify pooled pallet brands by their color: If you see a blue pallet at a store like Home Depot, that’s a CHEP pallet; a red pallet comes from competitor PECO.

The Most Powerful Weapon

Saturday, September 8th, 2012

The most powerful weapon the North Koreans have is the smart phone — in the hands of South Korean conscripts:

In many cases, smart phones are not allowed on military bases. All this because smart phones distract soldiers from their work, especially boring chores like guard duty. This was discovered, with increasing frequency over the last few years as NCOs and officers out, especially at night, checking up on the guards, found the troops engrossed in some smart phone game, or texting or reading an e-book. Despite a growing number of soldiers being punished for having, and misusing, smart phones on duty, troops continue to risk using the devices.
