Flint & brecciated flint from the Pennsylvanian of Ohio, USA.
Flint is the "official" state gemstone of Ohio (actually, there's no such thing as "official" anything). "Flint" is sometimes used as a lithologic term by modern geologists, but it is a synonym for chert. Flint and chert are the same - they are cryptocrystalline, quartzose sedimentary rocks. Rockhounds often assert that flint is high-quality while chert is low-quality. Some geologists assert that "flint" implies a biogenic origin and "chert" implies a chemical origin.
Many cherts do have a chemical origin - chert nodules are moderately common in some limestone units. The nodules form during diagenesis - pre-existing silica components in the carbonate sediments are dissolved, mobilized, and reprecipitated as chert masses. Some cherts do have a biogenic origin - for example, radiolarian cherts (rich in radiolarian microfossils) or spicular cherts (rich in siliceous sponge spicules).
The most famous flint deposit in Ohio is Flint Ridge, in Licking County. At this locality, the Middle Pennsylvanian-aged Vanport Flint is exposed in several places. The geologic literature on the Vanport Flint is relatively sparse, with inaccurate, incomplete descriptions and characterizations. For example, the literature describes the Vanport as a sheet of flint at Flint Ridge - it's actually a meganodule horizon. Other descriptions refer to the chert as the remains of siliceous sponges. In reality, siliceous sponge spicules are quite scarce in Vanport samples.
Two graduate student projects during the 2000s, conducted at two different universities, had very different conclusions & interpretations about the origin of the Vanport Flint. A 2003 study concluded that chert at Flint Ridge is biogenic in origin. A 2006 study concluded that the chert is chemical in origin.
Modern flint knappers value the Vanport Flint for being multicolored and high-quality (= very few impurities). With artificial heating, the flint is more easily knapped into arrowheads, spear points, and other objects. Prehistoric American Indians quarried the Vanport Flint at many specific sites on Flint Ridge. Old Indian flint pits can be examined along hiking trails in Flint Ridge State Park ("State Memorial"). Many authentic Indian artifacts found in Ohio (arrowheads & spearpoints - "projectile points") are composed of Vanport Flint.

Some Pennsylvanian-aged cherts in eastern America are inferred to be ultimately derived from quartzose eolian dust on seafloors.

NGRREC researchers launched PISCES (Pontoon for In-situ Characterization of Environmental Systems) into the Mississippi River for the first time in October 2012. PISCES (Pontoon for In-situ Characterization of Environmental Systems) is a lightweight pontoon platform that supports water quality and meteorological sampling. The device will be deployed as part of the National Great Rivers Research and Education Center's long term river monitoring research program, GREON (Great Rivers Ecological Observation Network). The device will be the first water sampling platform to be used in a larger network of water quality platforms on the Mississippi River and large rivers around the world. Photo by S.

The Malaria Program and the Institute for Biomedical Sciences in Suriname (MWI) are cooperating on conducting scientific studies of molecular screening with Real-Time PET PCR for malaria identification (even with very low parasitaemia). In addition the MWI explores the potential use of malaria serology in Suriname and introduce serological testing to allow the country to gradually declare areas of the territory free from malaria. In addition the emerging of Artemisinin resistance can be assessed through molecular characterizations and drug sensitivity studies.
The Malaria program receives technical support from individual infectious disease expert from the Academic Hospital.
David Scarbie Mitchell applies a simple character face for his one man show LipSchtick. Actorly characterization or impersonation depends more on physically, vocal impressions and costuming than extensive make up. The results are uncanny!

A typed postcard addressed to lifelong friend Ed White and signed "Jack" at conclusion, in which Kerouac discusses On the Road, its publisher Malcolm Cowley, and the characterization of Justin W. Brierly within the novel. Written just two years after the book's publication, this air mail-postcard has been stamped from Northport, NY on December 30, 1959 and measures 5.5" x 3.25" overall. The "J" of "Jack" written in blue pen has been slightly cut off along the bottom edge, with minor printing flaws present from the typewriter as well as some smudging to recipient's name and address. Condition is near fine with incredible contents.
In full, with original punctuation maintained:
"Sir,
Yes, I am mindful that Jinge was looking for me,
but I am immersed in the fragrance of womanhood as tis…
Glad to see the pictures of your bumpkins..
If Truman would have his way they'd get even more
radiation, hey? ------ Have you seen the reference to
Justin W. [Brierly] in the December issue of Playboy… This will
make up for the deletions of his characterhood that were
made by Malcolm Cowley in On the Road in the days before
I started putting my foot down about editorial inter-
ference with my statements, sir……
I just drove back with friends from west coast but thru
New Mexico where I penned the following poem:
'Wheat silos are huge trucks waiting for the road
to approach them.'
What are we doing in the middle of eternity bored? Jack"

The Kerosuo lab aims to understand how the neural crest maintains its exceptionally high stem cell potential and what ultimately triggers its fate commitment. Characterization of the events at the molecular level by using both in vivo and in vitro animal and patient derived model systems will also elucidate defects in neural crest-derived cancers and other neurocristopathies that comprise a quarter of congenital birth defects.

My friend Eric and I went out to an alley way downtown. We were lucky that no one bothered us to leave. This was for a characterization project in my portraiture class. I chose Bond, James Bond. Pretty awesome shoot. It's nice to shoot with another photographer, he understood my concept and what I wanted to do. You can find Eric's work here.

"Well, George, I must say that I am deeply hurt over your sloppy, ideologically addled mis-characterization of me and my business in this little 'moving picture' of yours.
I say I have enjoyed more balanced representations of the private sector in third-rate Federal Theatre Project plays acted from the back of a pick-up truck in some farmer's field.
For that matter, the worst of your...Mr...Stalin's...state theatre portrays me and my brethren in a fairer light.
You... admire...that...Mr.... Stalin..., don't you, George?"
Well, you once called me a warped, frustrated old man. Well look at me now; I'm an illustration in New York Magazine's hit piece on Governor Christie. " Go ahead, George, click the link: nymag.com/daily/intel/2011/07/punchiminhishead.html

We were here last fall- the trail of tears back east for the holidays started here, at least by Sharon's characterization. It's maybe 5 miles north of Plaskett Creek campground, and on the ocean side of the Pacific Coast Highway, so instead of a little glimpse of the ocean through the trees you have a panoramic view from 170 feet above the water,. This view is almost straight west, and the coast here goes SE to NW. Sharon insisted on this very non-level campsite the first night we were here, which was so bad the refrigerator barely worked. We moved to a much better spot the next morning.

Suspended Animation Classic #616
First published October 15, 2000 (#42) (Dates are approximate)
The First
By Michael Vance
The Good. The Bad. The Ugly.
The First.
The Good: The art on The First, the newest comic book from Crossgen, is exceptional. Dynamic. Engaging. Flawless visual storytelling. Its artist, Bart Sears, is among the best in the artform today.
The Bad: Characterization is overwhelmed by melodramatic plot and dialog. Art is emphasized over story. The first First is simply an extended fight scene.
The Ugly: It will not attract the huge non-comics reading public to the artform, one of the stated and important goals of its publisher.
The First is the epic tale of two warring nations and the gods who created and manipulate them. Look under Homer in your local library.
They are a nation of people who embrace heroic poses against magnificent backgrounds, They are an extremely literate people who say things like: “Gods of the world and spirit, this unworthy one humbly begs your notice!” Briefly, they are a Wagnerian opera without music or the movie Braveheart without the nuances of human personality or natural dialog.
Hopefully, those human nuances will develop in the second or following issues of this new series. If they do not, this title will fail. My guess is that, regrettably, the stilted dialog is there to stay.
It is a regret because comic books desperately need to expand their audience, and the talent to attract that audience can definitely be found in The First. Without the excessively grandiose poses and dialog, and with a focus on character over plot, there is no reason it should not reach the same adult audience that made Braveheart a success.
Until the editorial philosophy that underlies the industry recognizes this, and a few other marketing problems are overcome, The First and most other comic book titles still fixated on superheroes will remain second class media citizens.
The First is recommended for readers who enjoy epic fantasy.
The First #1/$2.95 and 27 pages/words: Barb Kesel/sold in comics shops and by mail.
