(left) Peridotite xenolith from a quarry near Yangyuan, China was erupted onto the surface approximately 38 million years ago. Materials like this are examined in order to study the evolution of the lithospheric mantle underlying the North China Craton. Evidence suggests that the ancient lithospheric mantle that underlay China as late as the mid-Ordovician has been replace by younger mantle represented by the rock shown.
(right) Apollo 16 pristine lunar anorthosite 65035. This rock likely formed during the creation of the lunar crust, possibly via flotation from a magma ocean. The anorthositic portion of this rock is characterized by very low abundances of highly siderophile elements, indicating that the Moon's long history of meteorite bombardment did not chemically modify the rock. The rock is, however, coated with a glass splash, consistent with impact melting near the rock.
The Isotope Geochemistry Laboratory (IGL) is part of the Geochemistry Laboratories of the Department of Geology, University of Maryland. The IGL was created in 1991 by Profs. R. J. Walker and E. J. Krogstad in order to pursue state of the art isotopic and trace element analysis of geological and cosmochemical materials. Currently, the IGL comprises a set of five laboratories for the preparation and isotopic analysis of a wide range of geological materials. These laboratories include separate mass spectrometry, chemistry, mineral separation and rock preparation facilities. The IGL began operations in 1991 with the acquisition of a 12 inch radius of curvature NBS single-collector, solid source mass spectrometer. In 1992 a VG Sector 54 mass spectrometer with 7 faraday collectors, was added to the complement of analytical tools. A third thermal ionization mass spectrometer, a Thermo Fisher Triton, with 9 Faraday cups was installed in 2007. The NBS and VG mass spectrometers were retired from UMd service during the summer of 2014, ending their careers with us with 10,261 and 14,479 individual analyses, respectively. The NBS instrument was donated to Miami University, and the VG was donated to the University of Alabama. In their place a new Thermo Fisher Triton Plus was installed in the fall of 2014. A second mass spectrometry laboratory, shared with the Plasma Laboratory, houses a Nu Plasma multi-collector inductively coupled plasma mass spectrometer, as well as an Element 2 single collector ICP-MS. Operations of the IGL are primarily supported via the University of Maryland, and grants from the NSF and NASA. An overview of the types of research conducted within the IGL at be found at our research homepage.
The mission of the IGL is to produce the highest quality isotope data, to innovate in techniques development and applications, to train students and visitors the techniques involved in gathering such data, and to maintain itself as a world-class isotope measurement facility.
The Thermal Ionization Mass Spectrometry Laboratory (CHEM 0218) of the IGL currently houses two solid source mass spectrometers, two filament degassing apparatuses, and laminar flow benches for sample loading. Each mass spectrometer has dedicated ion optics sources for Re and Pt filaments.
Photos show the UMd Thermo Fisher Triton mass spectrometers.
The Thermo Fisher Tritons were installed in 2007 and 2014. These instruments are primarily used for high precision measurement of W, Nd, Sr, Os, Ru and Mo isotopes as applied to geological/cosmochemical projects.
The Nu Plasma multi-collector ICP-MS uses high temperature plasma to ionize elements that have been either chemically separated and purified from a material, or liberated from a solid matrix via laser ablation. The relative intensities of the different isotopes of a given element are quantified using either the multiple faraday cups or multiple electron multipliers. This instrument is commonly used to measure the isotopic compositions of Mo, Li, W, Pt, Ru, Ir, Pd and Re.

Most samples for isotopic analysis are processed (elements of interest are purified from matrix) in the Chemistry Clean Laboratories. Two 500 sq. ft. laboratories are supplied with HEPA filtered air. Each contains class-100 vented laminar flow hoods, chemical fume hoods and multiple work stations (with fume extraction). The facility also utilizes two Milli-Q water purification systems, and currently operates eight sub-boiling stills (quartz and teflon).

The Sample Digestion Laboratory (CHEM0221) and Rock Preparation (CHEM0219) laboratories were most recently renovated in 2002-2003. The Rock Preparation lab houses, short-term sample storage, a ceramic jaw crusher and disk mill, alloy mortar and pestle, rock splitter, SPEX Industries Shatterbox and Mixer Mill (both with agate and alumina grinding chambers), and a Leco diamond slow-speed saw for cutting iron meteorites. The Sample Digestion lab houses two ovens (one can achieve temperatures as high as 380°C), one muffle furnace, both oxy-propane and oxy-hydrogen torches (for sealing Pyrex and quartz Carius tubes) and an Anton-Paar high pressure asher (HPA). The asher is used for high temperature digestions of samples for Os isotope and highly siderophile element measurement.

Some of the main thrusts of research in the IGL include studies of the mantle and crust, the isotopic evolution of the oceans, and the evolution of the early solar system. Applications also target tectonic and environmental problems. The range of specific research topics currently active in the IGL include:
- The evolution of siderophile elements in Earth's mantle and crust through time. Recent targets of interest include mafic-ultramafic rocks (including komatiites and ophiolites) from South Africa (Barberton Greenstone Belt komatiites), Zimbabwe (Belingwe komatiites), Finland (various komatiites and ophiolites), Canada (Abitibi Greenstone Belt komatiites), United Kingdom (Unst Ophiolite), Norway (Leka ophiolite), Chile (Taitao ophiolite), Switzerland (Totalp Massif) and Russia (Vetreny and Kostomuksha komatiites), as well as oceanic rocks including abyssal peridotites.
- Use of 182Hf-182W, 187Re-187Os and 190Pt-186Os isotope systems to study mantle heterogeneities resulting from primordial planetary differentiation processes and possible interactions between the Earth's core and lowermost mantle. Targeted rocks include ancient komatiites and modern ocean island basalts.
- The chronology and chemical evolution of solar system materials. Specific targets include iron meteorites, pallasites, chondrites, lunar volcanic glasses and basalts, lunar highland breccias, martian meteorites and presolar grains. These studies include the application of short- and long-lived chronometers based on radioactive decay, and research on isotopic heterogeneities in meteorites and their implications for stellar nucleosynthesis, nebular mixing and early evolution of the solar system.
- Study of peridotite xenoliths plucked from the subcontinental lithospheric mantle as a means of constraining the age of lithospheric mantle creation, assemblage and possible destruction (in some regions, such as underlying the North China Craton). Work is currently centered mostly on samples from China and Antarctica.

Hello folks,
I've been doing websites for a while for my band, and i recently found wordpress. it seems pretty cool so far, and i'm trying to use for my bands new website. one problem, i have created multiple pages, and i wanted to place an audio player widget that would keep a song playing while a user navigates the site. i really hate frames and don't want to do this way. is there a place i can put the widget that won't get reset every time the next page loads? or is there a better way to do this?

The Covenants of the Prophet: Read an Excerpt
Doubtless, the promise of protection until the Day of Judgment was contingent upon the Christians upholding their side of the bargain. If they rebelled against Islamic rule, if they aided and abetted the enemies of Islam, such as the Crusaders, or, more recently, European colonizers, and American imperialists, the covenant would no longer apply to them and would be effectively annulled. This is not to suggest that the covenant is currently null and void or that it represents a missed opportunity which cannot be recovered; the fact is, it has been largely adhered to for more than a millennium. Nor does this imply that the Prophet was oblivious to the flaws and devilish nature of men. It remains, as always, a model for relations between Muslims and Christians and the basis on which to build bridges. It is the foundational stepping-stone for all negotiations, treaties, and accords between Muslims and Christians.
Although many Christian communities violated their oaths, the monks of Mount Sinai have always maintained the utmost respect for Muhammad. Not only have they upheld the covenant made with the Prophet, they have cherished it always as their most valued possession. In a recent statement, the Monastery of Saint Catherine had this to say about the Prophet Muhammad, his contacts with the monks of Mount Sinai, and the covenant he concluded with them:
According to the tradition preserved at Sinai, Muhammad (AS) both knew and visited the monastery and the Sinai fathers. The Koran makes mention of the Sinai holy sites. In the second year of the Hegira, corresponding to ad 626, a delegation from Sinai requested a letter of protection from Muhammad (S). This was granted, and authorized by him when he placed his hand upon the document. In AD 1517, Sultan Selim I confirmed the monastery's prerogatives, but took the original letter of protection for safekeeping to the royal treasury in Constantinople. At the same time, he gave the monastery certified copies of this document, each depicting the hand print of Muhammad (S) in token of his having touched the original. (Sinai Monastery)
Considering that the Monastery of Saint Catherine contains the largest collection of Christian documents and codices after the Vatican Library, and is described as a "veritable conservatory of the Christian Orient" (Géhin 163), the library at Mount Sinai is precisely the place where one would expect to find a priceless document like the Patent or Covenant of Muhammad.
While Muslims and Christians may differ on certain issues, they largely agree on the content of the covenant. Besides the monks of Mount Sinai, the authenticity of the Patent of Muhammad has been attested to by John Davenport in his Apology for Mohammed and the Koran (148). For Davenport, "[t]he . . . facts and arguments" contained in the covenant "will, it is presumed, suffice to convince every candid and unprejudiced mind that this second charge against Mohammed," namely, the allegation that Islam was propagated by the sword, causing an enormous waste of human blood, and a vast amount of human misery, "being utterly devoid of foundation, is, therefore, both false and scandalous" (151). In fact, the authenticity of The Covenant of the Prophet Muhammad with the Monks of Mount Sinai has been recognized by a long list of Muslim scholars, including, Dr. A. Zahoor, Dr. Z. Haq, Dr. Muqtedar Khan, Dr. Reza Shah-Kazemi, and endorsed by numerous Islamic associations such as the Islamic Supreme Council of Canada. Such is the example of true Christian-Muslim relations.

Ocala Teens Try to Kill Parents
Published March 10th, 2014
Loading Video...
Young love got the best of two Ocala teenagers, who were so desperate to be together, they tried to kill their parents who didn't approve.
13-year-old Yaquelin Galvez Don's parents didn't want her dating 15-year-old Pedro Solis.
The two teens talked about killing her parents over the phone and on Facebook throughout last week.
Late Saturday night, Don lured her mother into their garage, where Solis was waiting.
He sliced the mother's throat and then threatened to do the same to the father, who is wheelchair bound.
"This was apart of their plan. In some way, the 13-year-old and the 15-year-old decided that by killing the mother, they would be able to be together at that point."
The father convinced Solis to take his wife to the hospital.
She had life-saving surgery and is now recovering from her injuries.
The teens have been charged with conspiracy to commit murder and attempted murder in the second degree.

It was raining hard during the whole race, and court wasawesome except the climbing and slippery part. Unfortunately this was a verybad organized race, almost half of the participants didn't catch up the starttime due to all the race categories were ahead of time to play. Hopefully therace organizer could be more professional and respectful those participants whorode 1hr in the hard rain to join the race! But anyway, the team had a greatpost-race meal together, and it's always feeling great to stay with ActiveXteam.

I've just successfully configured wpDirAuth to work with our LDAP, and much seems good. I have several questions at this point:
- The "Lost Password" link shows up on the login page for both LDAP authenticated and existing users, though it's only applicable for the latter. Is there a way to hide this for LDAP authenticated users, since they are supposed to update their passwords via our institutional link?
- I just discovered what seems to be a password security issue with LDAP-authenticated users, which I'll email you separately...not sure if it's due to wpDirAuth, our LDAP server, or something else, but it's crazy.
- We have a number of existing users whom I'd like to convert to LDAP-authenticated users. They registered using their institutional login as username. The only distinguishing characteristic I see in wp_usermeta is that wpDirAuthFlag is set to 1. If we do so manually for existing users, would this then authenticate logins against our LDAP?
Thanks again for the great plugin, and appreciate input on the above.

By Brittany Carlson, Belvoir EagleOctober 31, 2013
With a blast of gunfire, Soldiers fired not bullets, but lasers at Fort Belvoir's Essential Skills Trainer simulated marksmanship range Oct. 25.
The noise is one of many factors that make the indoor range seem like the real thing -- such as the M9 pistols, M16 rifles and M60 machine guns that are identical to actual weapons, down the weight of the cartridges -- except for the fact that they don't require bullets.
"It's cost-saving equipment that is as close to the real thing as they're going to get," said Dana Winslett, Directorate of Plans, Training, Mobilization and Security range specialist on Fort Belvoir.
About 6,000 servicemembers and law enforcement personnel from Fort Belvoir and surrounding installations use the EST each year, Winslett said, as an alternate to driving to the nearest live-fire range at Fort A.P. Hill or Marine Corps Base, Quantico.
The simulated weapons meet the Army specifics for operation, weight and functions, and offer training year round, without the logistical requirements of an actual range, Winslett said.
They even kick back like real weapons and make the same noise, although the volume can be controlled in the enclosed space.
"I think it's great for familiarization," said 1st Lt. Katty Velezrivas, Headquarters and Headquarters Company, 1st Battalion, Warrior Transition Brigade, who has trained on the M60, M4 and M16 at the EST. "You can adjust in a more comfortable environment, so when you actually go out there to qualify, you are already so comfortable with your weapon."
Units can book the five-lane Essential Skills Trainer, or EST 2000, to qualify on the M9, or practice shoot/don't-shoot scenarios and small-unit tactics with the weapons they would have in the field, Winslett said.
The EST 2000 also saves the Department of Defense money that would have been spent on the ammunition, transportation fuel, medical support, and personnel needed to conduct a live fire range, Velezrivas said.
"Logistically, it is definitely an asset, because now you need fewer personnel to transport ammo and fewer personnel to run the range," she said.
"You can have it open for longer times, and weather wouldn't have an impact either, so you can train no matter what the weather is," she added. "It's just a win-win all around."
The EST 2000 is in Building 1139 (next to Warrior Training Center) behind the South Post Shoppette.

We have learned at Foodfacts.com that a new snack is being brought to life. If you're a South Park fan, chances are you're familiar with Cartman's favorite snack, Cheesy Poofs, which are basically known to most as cheese puffs. For over 15 seasons now, South Park has created a product that has become infamous to Comedy Central fans despite not actually existing. It seems that now, however, the long wait is over. Cheesy Poofs are now being created, and they are coming to markets.
Wal-Mart will begin selling approximately 1.5 million packages of Cheesy Poofs for about $2.99 starting in August. Teaming up with Frito-Lay and PepsiCo, South Park creators Trey Parker and Matt Stone have agreed to create a product that millions of viewers have grown to love these past 15 seasons.
On the other hand, what will all of us consumers fed up with processed snack foods think? We do not yet know the nutritional value of this product, or the ingredients, but we're anticipating Cheesy Poofs to be like all the other "cheese-flavored" snack products, loaded with junk. This product will only be available for a limited time, so check out the ingredients while you can!

Actor and musician Declan Bennett has successfully maintained dual, often intersecting careers as a singer-songwriter and musical theatre performer. He's had chart hits both with band Point Break and as a solo artist, and has tackled several iconic roles, including Roger in a US tour and Broadway run of Rent, Guy in the UK premiere of Once, and now Jesus in Andrew Lloyd Webber and Tim Rice's Jesus Christ Superstar. This new production at Regent's Park Open Air Theatre celebrates 45 years since the show first opened, and the intimate, gig-like experience - with performers playing instruments - promises to be very different to the recent arena tour.

Today, in honor of Holy Week, we shine a special spotlight on one of the most revered and rockin' musicals ever written, Andrew Lloyd Webber and Tim Rice's JESUS CHRIST SUPERSTAR. (more...)
Today in 1970, JESUS CHRIST SUERSTAR creators Andrew Lloyd Webber and Time Rice received gold records for the original cast album of the show. The musical started off as a rock opera concept recording before its first staging on Broadway in 1971. The musical is based very loosely on the Gospels' account of the last week of Jesus' life, beginning with the preparation for the arrival of Jesus and his disciples in Jerusalem, and ending with the crucifixion. It highlights political and interpersonal struggles between Judas Iscariot and Jesus, struggles that are not in the Bible. The resurrection is not included. It therefore largely follows the form of a traditional passion play. (more...)
Classic concept album and variably successful stage piece CHESS has had a colorful history unlike virtually any other modern musical theatre piece, yet the strangest story of all in the show's thirty-year trajectory may be the unexpected Top Ten hit enjoyed by one of the score's most contemporary-sounding tunes, 'One Night In Bangkok', analyzed in a new WNYC podcast as part of Soundcheck's That Was A Hit?!? series.

For musical theatre lovers Down Under, 2012 gave us much to sing and dance about. We watched new musicals struggle to find their footing, a 60-year old classic make its triumphant return, and premiered blockbuster hits straight from the West End. In a year where we were spoilt for choice, it took much deliberation for this Broadway baby to narrow it down to a top five for 2012! (more...)

The Working Stiff had to check his work. Nope, didn't fall through.
The Stand Up milestone is reached! Any idea why the kid is smiling?

I can't believe how much the kids have grown! Seems like just a short time ago Bittygirl was a toddler in a pink panzer.
Here's the funny part. Spiderboy was 4 when I met he and Msdrby. Bittygirl is now 4, and doing exactly the same stuff he did at that age.
Hobbit Lass has grown a spurt too.
Bitty Girl and Hobbit Lass are both lucky to have dads who'll teach them stuff.

Why thank you. We think so.
It is so good to cyber-see you again. I was just thinking about you last week. Hobbit Lass came in from an exciting night, jumped on my bed, and couldn't stop talking about her evening. I remembered you telling me that your daughters did that. :^)
Are you all partying without me? ;^)
We're doing our best.

For the outer roof, I haven't quite decided yet. Either aluminum or a vinyl used for tonneau covers.

Lookin good there PE. Hopefully the September debut will be a success

Sunday, November 16, 2008. (AP) -- Syracuse coach Greg Robinson was fired Sunday with the Orange two games away from finishing a fourth straight dismal season under his leadership.
Robinson was 9-35 in three-plus seasons at Syracuse and 3-23 in the Big East. He had another year left on a contract that paid him $1.1 million per season.
Syracuse (2-8, 1-5) lost to Connecticut 39-14 Saturday night and is trying to avoid a third 10-loss campaign. The Orange had never lost 10 games in a season before Robinson was hired by athletics director Daryl Gross to replace Paul Pasqualoni after the 2004 season.
