using an agate mortar and pestle. Nova Scotian

(1989) also described extensive outcrops of “rubblized” basalt

(Fig. 415-420.

Previous studies suggested that the zeolite formation in the North

Mountain Basalt was the result of burial metamorphism (e.g. Zeolites are also present as irregular veins in the pug of a few

major faults. Minerals associated with the

zeolite minerals include quartz and other forms of silica (e.g.,

chalcedony, amethyst, agate, jaspar, opal), malachite, mica, barite, and

they commonly filled with neptunian dykes of red sandstone and mudstone

an irregular silicified body (5 m in length, 1 m thick) appears to have

replaced permeable polymictic coarse litharenite. Slickensides in the basalt cataclasite are developed in

quartz and celadonite.

Silica minerals including quartz to “heulandite”

Chemical analyses of zeolite minerals from Arlington Quarry are

given in Table 2. New petrographic evidence in Pe-Piper (2000), such as

the repetitive zonation in some amygdales and the amount of metal

precipitates, suggest a hydrothermal origin. With falling temperature the crystallizing solution

became enriched in Na, and sodic zeolite minerals, such as natrolite,

began to crystallize. A few

zeolite veins cross-cut both the basalt and neptunian dykes, but are

much thinner in the dyke sediments (Fig. 3.68

[K.sub.2]O b.d. 1). As a result, only limited crystallization of Na-rich

zeolites (natrolite group) took place in the North Shore occurrences,

and the observed zeolites show a broad scatter in Na, Ca, Mg, and K

difficult because commonly more than one zeolite mineral was present in

any one hand specimen. In contrast, on the

North Shore the chemical data presented in this paper indicate that Na

was readily accommodated in the crystal structure of crystallizing

zeolites, which we interpret as a result of crystallization at lower

and silica minerals, with minor “heulandite”, chabazite, and

zeolitization is in the columnar-jointed basalt and irregular veins and

vugs, which is a response to the progressive deformation of the basalt

in a strike-slip, pull-apart setting.

Thomsonite is generally massive or fibrous, beige to off-white.

The zeolite minerals found on the North Shore of the Minas Basin

differ from those in Kings County and elsewhere on the south coast of

the Bay of Fundy in the presence of wairakite and barrerite, and in the

abundance of chabazite, which is rare on the south coast. Celadonite, silica minerals, “heulandite,”

analcime, and chabazite predominate in amygdales in the basalt flows and

in basalt clasts in the McCoy Brook Formation, suggesting that these

minerals were “early” (Fig. 152-159.

composition of zeolite minerals from the North Shore of the Minas Basin

and from Kings County may be the result of a difference in temperature

of formation and/or different fluid composition.

The purpose of this paper is: 1) to accurately identify zeolite

minerals of the North Shore of the Minas Basin using up-to-date

analytical techniques, thus establishing both their stratigraphic and

regional distribution; 2) to determine the order of crystallization of

zeolite minerals in each area and hence the events of zeolite formation;

3) to examine the chemical mineralogy of zeolite minerals of

representative samples and in particular zeolite species from these

areas with no published chemical analyses; 4) to establish the

differences in chemistry of some identified zeolite species between the

North Shore and the Arlington Quarry (a representative area of the type

North Mountain basalt in Kings County) (Fig. b.d. Zeolites of the Bay of Fundy. The oldest basaltic clasts in the McCoy Brook Formation

contain a similar mineral assemblage (including sparse

“heulandite” and chabazire) in amygdales, suggesting that the

In summary, the work of Schlische and Olsen (1989) showed that

extrusion of North Mountain Basalt and deposition of the immediately

overlying sediments of the McCoy Brook Formation took place during

active strike-slip faulting and the formation of a small transtensional

graben (Fig. Some authors have

compared the zeolite assemblages to those resulting from burial

Are ‘Mini-Nukes’ The New Big Thing?

Last year, the U.S. In the modern U.S. — did not prohibit designing a testing device with a yield below five kilotons, modifying an existing weapon for safety reasons or conducting research and development necessary “to address proliferation concerns.”

The move to clear the legal hurdles on manufacturing mini-nukes is part of a broad review of U.S. spent more in real terms on atomic defense activities than since 1962.

The ban — named after sponsors Elizabeth Furse, D-Ore., retired, and John Spratt, D-S.C. “Unless we do a lot more research and development and we find some quantum breakthrough in conventional systems, to go deep is going to require a nuclear capability.”

But some members of Congress believe conventional weapons could do the same job, and worry that mini-nukes would blur the line between conventional and nuclear weapons. Edward Kennedy, the administration has budgeted $700 million for studying how testing might resume. Crouch, the assistant secretary of Defense for International Security Policy, said in a briefing last year.

“How can we effectively seek to dissuade others from developing nuclear weapons while we are going forward with the development of new nuclear weapons ourselves?” Sen. Dianne Feinstein, a California Democrat, asked recently.

CBSNews.com’s Jarrett Murphy takes a look at the prospects for the U.S. conducted its last nuclear test in 1992, and while the White House opposes the Comprehensive Test Ban Treaty — which the U.S. wants to stop proliferation.

“Nuclear weapons have a unique ability to destroy both agent containers and (Chemical and Biological Weapons),” reads a 2001 Pentagon study.. But the administration says smaller nuclear arms may eventually be needed to deal with the emerging threat of rogue states hoarding weapons of mass destruction.

A kiloton is equal to the explosive force of one thousand tons of TNT.

However, the administration is paying increasing attention to the possibility that it might at some point have to resume testing if there were a question about the reliability of the nation’s stockpile. Last May, he and Russian President Vladimir Putin agreed to slash their active arsenals by nearly two-thirds, to 1700 to 2200 warheads each, within 10 years.

At the same time, however, last month the United States produced a plutonium pit — the core of a fission bomb — for the first time in 14 years. All rights reserved.

Announcing its approval of the bill Friday, the Senate Armed Services committee stressed that nothing in the repeal means it has authorized “the testing, acquisition, or deployment of a low-yield nuclear weapon.”

A memo obtained by a British newspaper indicates that at a conference this summer, Defense and Energy department officials will consider questions like: “What is the uncertainty in confidence and potential risk threshold for a test recommendation–what would demand a test?”

The defense appropriations bill now winding its way through the Hill contains a clause revoking the 1993 Spratt-Furse amendment, which prohibits the development of so-called “low-yield” nuclear weapons – bombs that pack a punch of less than five kilotons.

But some experts contend that no bomb of any size could go very deep, because the heavier the bomb, the harder the impact — and the harder the impact, the more likely the bomb would explode before it reached sufficient depth.

The EGen truck represents a zero-emissions, no-transmission, noise-free, smooth-driving, electric vehicle that could significantly reduce vehicle operating costs for the transportation company.

Two E-GEN Electric Workhorse Walk-in Trucks with small Onboard Generator are currently delivering in the field.

Built on the new, narrow track W88 chassis, the E-GEN trucks come with a 60 kWh lithium ion battery pack featuring Panasonic 18650 cells that provide power to a 2200 nm (268 bhp) permanent magnet motor powerful enough to eliminate the need for a transmission.

“Major transportation companies are always looking for sustainability as an integral part of operations,” said Steve Burns, CEO of [Workhorse Group Inc. (OTCQB: WKHS), is the manufacturer of the E-GEN Workhorse truck.

The advantage of an electric power train is zero tailpipe emissions, which helps reduce particulates and nitrogen dioxide in the atmosphere, and also offers dramatically lower operating costs for the owner. “The EGen onboard generator gives the truck many unique advantages over conventional gas and other typical electric vehicles.”

Workhorse E-GEN electric trucks are designed to meet the needs and expectations of daily delivery duty cycles, as well as save delivery fleet buyers fuel and operational costs, dramatically reducing total cost of ownership over the lifetime of the vehicle. “With the capability of recharging enroute, via the onboard generator, in the event of an unusual event that requires more than the average route length on a given day, range anxiety is virtually eliminated.

“The E-GEN zero-emission driving experience has the potential to reinvent the local delivery vehicle,” continued Burns. The Workhorse Group, Inc. manufactures electric drive systems for medium-duty, class 3-6 commercial truck platforms

W88 warhead program performs successful tests

CRAFT demonstrated how the radar performed during re-entry through plasma generated by the hypersonic speeds at which the warhead travels.

. Sandia and its partners are analyzing results to validate requirements and radar design.

Evaluating powerful batteries for modular grid energy storage

The June CRAFT test was the first of several planned flight tests to demonstrate the upgraded system’s performance. It also will use the information to validate computer models designed to apply the results to other drop scenarios, since it’s not possible to replicate every possible accident in tests.

Sandia National Laboratories performed a drop test for the W88 ALT 370 program, designed to replicate a crane accidentally dropping the re-entry body onto a concrete surface. The test was conducted at Sandia’s 185-foot Drop Tower Facility, using the same handling gear a crane would use to move the weapon.

The first flight and drop tests for the latest variant of the W88 nuclear warhead are providing data for Sandia National Laboratories to validate designs, improve computer modeling and update component specifications.

A month later, the first drop test of the W88 ALT 370 program mimicked a crane accidentally dropping the re-entry body onto a concrete surface to develop evidence that it would remain safe during an accident. An abnormal environment is one that is unexpected, such as an accident.

Sandia will use vibration and shock measurements from the test to update specifications for components in the weapon, he said. “The weapon is not required to function after that, just to stay safe,” Edwards said.

The two successful tests, which were conducted this summer, provide data for the program, the W88 ALT 370 (alteration), to move forward, said Tim Edwards, manager for the program’s technical basis and qualification activities.

It was the W88 program’s first abnormal drop test since the system’s original qualification test in 1987. It also represented a milestone: the first flight test unit Sandia and its partners, Los Alamos National Laboratory (LANL), the Kansas City Plant (KCP) and Pantex, delivered to the Navy for full-scale testing under the program.

The Critical Radar Arming and Fuzing Test (CRAFT) was the first flight test of a prototype radar for the W88 ALT 370. Using an unarmed re-entry body, Sandia conducted the test in partnership with LANL, KCP and Pantex at Sandia’s 185-foot Drop Tower Facility, using the same handling gear a crane would use to move the weapon, making the test as realistic as possible.

The new radar functioned as expected after launch on a Trident II missile from a Navy submarine, Edwards said

Brad Pitt takes son Pax for a ride in his motorbike and sidecar

The actor is now said to be planning to build an ambitious house over the falls near LA in the style of his favourite American architect, Frank Lloyd Wright.

The pair were taking a trip to a local grocery store in Los Feliz, where Pax emerged carrying a large paper bag.

The Moneyball star made sure him and his eight-year-old son stayed safe by wearing helmets and has obviously adapted his love for bikes to ensure it is a more child-friendly activity.

The long-haired actor was once involved in a crash on his motorbike while trying to escape the paparazzi but it doesn’t seem to have put him off.

However, despite the accident Pitt is obviously introducing his children to the mode of transport at a young age.

The Vietnamese child looked particularly excited as his father got him ready for the ride and relaxed in the sidecar as Pitt cruised the streets.

His other children Maddox, ten, six-year-old Zahara, five-year-old Shiloh and twins Knox and Vivienne, three, were nowhere to be seen yesterday but no doubt they’ll have their turns in the future.

Pitt was spotted cruising around California yesterday on his black Russian Ural Tourist motorbike, but he was accompanied by his son Pax in a sidecar.

California teenager kills himself playing Russian roulette

The two cousins asked him “not to do it,” before he held the gun to his head and shot himself one time, Deputy Juanita Navarro-Suarez told the Los Angeles Times.

A game of Russian roulette in southern California ended as it might be expected to, tragically, when a 17-year old boy shot himself in the head while playing the deadly game of chance.

. Soto fatally shot himself in the head, more closely mirroring the movie’s final scenes in which Walken’s character plays another round of the game in a seedy gambling den.

The incident in southern California is eerily similar to the death of a 20-year old Chilean man last month.

Jonathan Alejandro Tapia Jiménez, Soto’s 27-year-old friend, said he was too scared to play.

Bryan Javier Soto Aguilera, 20, asked a friend to help him reenact the scene in which Vietnamese guards force Robert De Niro and Christopher Walken – playing Vietnam-era prisoners of war – to play the deadly game of chance.

“I asked if he had real bullets, and, when he said he did, I told him he was crazy and I wasn’t interested,” Jiménez said, according to the New York Daily News.

The teen, who lived with his older brother and sister-in-law, was pronounced dead at a hospital. “I ran back inside and found Bryan lying on the floor in a pool of blood,” he said.

The game – made infamous in the 1978 film “The Deer Hunter” - has players put a single bullet in a revolver, spin the cylinder, hold the muzzle up to their heads and pull the trigger.

The teenager, who was unnamed in local media reports, shot himself fatally just after midnight on Monday while in his family’s home in Torrance, California, according to the Los Angeles County Sheriff’s Department.

Jiménez then went outside where he heard the bang from the gun. The gun is than passed around until it goes off.

In the film, however, De Niro’s character turns the gun on his captors. His death was ruled an accident, Navarro-Suarez said.

Column: FIFA presidency no laughing matter as would-be candidate becomes frontman for gambling

So silky as a player for Newcastle and Tottenham; so ridiculous now with his car-crash campaign for the FIFA presidency.

One of those is Kevin Twaddle, a former player for Motherwell and other Scottish clubs who told his story in the biography, “Life On The Line: How to Lose a Million and So Much More.” He no longer gambles and has delivered talks to other players about the risks.

Asking your kids to make tea during half-time breaks won’t shield them from the bombardment, not with gambling ads flashing throughout matches on pitch-side light-boards. But I mean you’re talking about one of the biggest, powerfulest jobs in football and all you’re getting to hear about is Paddy Power.”

. “There’s more passion, more pleasure and more pain.”

“I’m here today to talk about love” were the Frenchman’s seductive opening words at his campaign launch in London this month.

But that’s not the point here. 10 will pit two Asian online bookmakers against each other. Tuning in for results of football betting pools, which offered big jackpots for small stakes, was a Saturday afternoon ritual for many 20th Century English families.

Sport “matters more when there’s money on it,” it says. But the mere thought of the gambling industry even attempting to place a stooge at the very top of football makes the prospect of another Blatter term seem perhaps not quite so bad.

Bet. Bet again. Hull against Aston Villa on Feb. Villa’s shirt sponsor is dafabet, a name that works better in Chinese, where “dafa” means “big wealth.” Stoke and Burnley players are billboards for Bet365 and Fun88 (another name that plays on the Chinese word to get rich).

“It’s an absolute disgrace,” he said in a phone interview. Bet some more.

That is the message that football, more than most other sports, is mainlining into our homes, helped by names like Ginola and teams lending their cachet, stadiums, jerseys and players to the industry that had cash to splash when the 2008 financial crisis hobbled other sponsors.

Twaddle takes a very dim view of Ginola’s Paddy Power-backed grab for FIFA.

Sports and gambling have, of course, long gone together, feeding off each other’s success and growth. After Thursday’s passing of the entry deadline, “Team Ginola” should fade away.

Whoa. FIFA’s election and ethics rules will almost certainly keep him off the May ballot. It won’t happen; FIFA’s ethics rules should see to that. Ginola has zero chance of unseating Sepp Blatter. What ever happened to sport for sport’s sake, for the buzz of competition, not a bet? How quaint. “It’s great for Paddy Power. That much was clear from the Paddy Power branding.

We’re talking here about David Ginola. It reads like a plug for Fifty Shades of Grey.

John Leicester is an international sports columnist for The Associated Press. This was about making a splash. That was before online bookmakers offered odds on anything and everything, from match results and goals scored to which team will win the coin toss or take the first corner, and before their relentless advertising.

“It’s eyeballs we’re after,” 12Bet executive Rory Anderson, quoted in the Daily Mail, said when the online bookmaker became the name on Hull City’s shirt for this Premier League season.

PARIS –  Don’t laugh. Write to him at jleicester@ap.org or follow him at http://twitter.com/johnleicester

Imagine, for a moment, a Paddy Power-financed FIFA president. There’s nothing funny about the gambling industry’s latest wheeze to sink its teeth even deeper into football and its fans.

“It just makes like a mockery of football.”

But gambling advertising wasn’t as in-your-face as now. In the UK, which liberalized gambling advertising in 2007, adults’ exposure to gambling commercials on television soared five-fold in eight years to 2012, regulator Ofcom found. In pocketing 250,000 pounds (335,000 euros; US$375,000) from bookmaker Paddy Power for this stunt, Ginola became the latest Trojan horse in the gambling and gaming industry’s creeping and creepy embrace of football.

And that isn’t funny at all.

But the targets were our wallets and spending habits, not our hearts. The increase was three-fold for children aged 4-15.

All this in a sport grappling with the increasing danger of gambling-related match-fixing and with ample examples of gambling-addicted players who frittered away their wealth.


And how about this blurb from Sky Bet, title sponsor since 2013 of England’s three divisions below the Premier League

Racy Vietnamese cafes targeted by Calif. city

Some coffeehouses had six or eight arcade games running, and crime was on the rise, Nightengale said.

Officers plan to make rounds of the 37 Vietnamese cafes in the suburban city of Garden Grove to ensure they don’t have arcade games that have been rigged to let patrons bet on blackjack and roulette, and that scantily clad waitresses leave something to the imagination.

Orange County is home to the biggest Vietnamese immigrant community in the country, with sizable enclaves in Garden Grove and surrounding cities.

“We just serve coffee, wear bikinis, like Hooters,” Tran said. “I don’t know how long we can survive like this — with no money and losing customers.”

“When you’re running illegal gaming and further complicating the issue by having a quasi-strip bar …

GARDEN GROVE, Calif. What began more than a decade ago with waitresses in skimpy outfits morphed into nudity. “Starbucks is boring.”

Between January 2010 and May 2011, police received reports of three robberies, four assaults with a deadly weapon, and seven drug-related incidents at coffeehouses — a far cry from the tranquility at the city’s more traditional cafes, Nightengale said.

. Jeff Nightengale said.

The crackdown comes after authorities reported crime was on the rise outside coffeehouses.

“It’s a stimulating environment,” said Nguyen, of nearby Irvine. And patrons are being urged to smoke outside.

The Garden Grove City Council recently passed new rules to ban arcade games, darkly tinted windows and nudity at cafes. This material may not be published, broadcast, rewritten, or redistributed. Coffeehouses will be fined $1,000 for each violation.

One of them was Mike Nguyen, a 53-year-old day trader who said he doesn’t mind the thick stench of cigarette smoke and wishes authorities would ease up on the coffeehouse that has become his virtual office and escape from the cookie-cutter Southern California suburb where he lives.

The dimly lit coffeehouse in the heart of Orange County’s Little Saigon hopes to get a passing grade when police start enforcing a host of new rules to crack down on illegal gambling and nudity at some cafes starting as soon as this weekend.

On a recent weekday afternoon, a dozen loyal patrons converged at Cafe Miss Cutie to play Chinese chess, watch European soccer on flat screen TVs and sip iced coffee served by a waitress in a see-through lavender negligee.

Do, whose small cafe is brightly lit, said she relies on loyal, older patrons to stay afloat. But with the new restrictions, she fears her customers may venture over to coffeehouses in nearby cities where there are fewer limits.

“They say if it’s just to drink coffee, then I’ll stay home and drink coffee,” said Thuy Do, owner of Cafe Chichi in Garden Grove.

Tucked into strip malls featuring McDonald’s and Subway restaurants, the coffeehouses cater to men toting laptops to take advantage of free wireless access, who are meeting business partners or who are getting together with friends to play cards, watch sports and flirt with waitresses who pour iced drinks.

“Now it is a little boring to just come and drink coffee and read the paper,” she said.

Business has fallen at many of the cafes since police started the crackdown — above all on the arcade games that lured customers off their couches and got them to linger longer at the coffeehouses.

In March, authorities arrested 23 people at coffeehouses in Garden Grove and Westminster for investigation of illegal gaming and seized more than 180 machines and more than $145,000 in cash, Garden Grove police said.

At Cafe Miss Cutie, sales have been halved since police began making rounds several months ago, manager Tuyen Tran said.

But authorities in Garden Grove — a city of 170,000 people about 30 miles southeast of Los Angeles — said cafes have gotten out of control. – At Cafe Miss Cutie, the windows are tinted but not pitch black.
