This thesis presents a case study on an urban arterial corridor consisting of four intersections located in Baton Rouge, Louisiana. The research evaluates alternative roundabout designs in order to improve traffic flow through a currently congested corridor. The objectives of the research were to evaluate the effect of roundabouts in an urban arterial corridor, select the best alternative for the given corridor characteristics, and test the capacity of the alternative roundabout corridors. The three alternatives that were considered as part of this study were the existing signalized corridor, a partial two-lane roundabout corridor, and a partial three-lane roundabout corridor. Field data was used to model the alternatives in VISSIM, a micro-simulation software. Statistical analysis software, SAS Enterprise Guide 6.1, was used to analyze the results and determine if there were significant differences between the results for each alternative and each intersection. The performance measures used to compare the alternatives were average vehicle travel time, average delay per vehicle for each corridor, and average delay per vehicle at each intersection. The results showed that the overall alternative roundabout corridors provided a benefit over the existing signalized corridor for the existing traffic volumes tested. The partial three-lane roundabout provided the lowest vehicle travel times and lowest average delay due to the added capacity. For the higher traffic volumes at the interchange, the partial two-lane roundabout had a higher average vehicle travel time exiting the exit ramp than the existing corridor. The statistical analysis of the average vehicle delay at each intersection indicated that there were no significant differences between the alternatives at a five percent level of significance at the interchange. These results revealed potential operational issues roundabouts encounter at an interchange intersections.

The Unique Burial of a Child of Early Scythian Time at the Cemetery of Saryg-Bulun (Tuva)

<< Previous page

Pages:  379-406

In 1988, the Tuvan Archaeological Expedition (led by M. E. Kilunovskaya and V. A. Semenov) discovered a unique burial of the early Iron Age at Saryg-Bulun in Central Tuva. There are two burial mounds of the Aldy-Bel culture dated by 7th century BC. Within the barrows, which adjoined one another, forming a figure-of-eight, there were discovered 7 burials, from which a representative collection of artifacts was recovered. Burial 5 was the most unique, it was found in a coffin made of a larch trunk, with a tightly closed lid. Due to the preservative properties of larch and lack of air access, the coffin contained a well-preserved mummy of a child with an accompanying set of grave goods. The interred individual retained the skin on his face and had a leather headdress painted with red pigment and a coat, sewn from jerboa fur. The coat was belted with a leather belt with bronze ornaments and buckles. Besides that, a leather quiver with arrows with the shafts decorated with painted ornaments, fully preserved battle pick and a bow were buried in the coffin. Unexpectedly, the full-genomic analysis, showed that the individual was female. This fact opens a new aspect in the study of the social history of the Scythian society and perhaps brings us back to the myth of the Amazons, discussed by Herodotus. Of course, this discovery is unique in its preservation for the Scythian culture of Tuva and requires careful study and conservation.

Keywords: Tuva, Early Iron Age, early Scythian period, Aldy-Bel culture, barrow, burial in the coffin, mummy, full genome sequencing, aDNA

Share All sharing options for: Gagarin Cup Preview: Atlant vs. Salavat Yulaev

Gagarin cup (khl) finals:  atlant moscow oblast vs. salavat yulaev ufa.

Much like the Elitserien Finals, we have a bit of an offense vs. defense match-up in this league Final.  While Ufa let their star top line of Alexander Radulov, Patrick Thoresen and Igor Grigorenko loose on the KHL's Western Conference, Mytischi played a more conservative style, relying on veterans such as former NHLers Jan Bulis, Oleg Petrov, and Jaroslav Obsut.  Just reaching the Finals is a testament to Atlant's disciplined style of play, as they had to knock off much more high profile teams from Yaroslavl and St. Petersburg to do so.  But while they did finish 8th in the league in points, they haven't seen the likes of Ufa, who finished 2nd. 

This series will be a challenge for the underdog, because unlike some of the other KHL teams, Ufa's top players are generally younger and in their prime.  Only Proshkin amongst regular blueliners is over 30, with the work being shared by Kirill Koltsov (28), Andrei Kuteikin (26), Miroslav Blatak (28), Maxim Kondratiev (28) and Dmitri Kalinin (30).  Oleg Tverdovsky hasn't played a lot in the playoffs to date.  Up front, while led by a fairly young top line (24-27), Ufa does have a lot of veterans in support roles:  Vyacheslav Kozlov , Viktor Kozlov , Vladimir Antipov, Sergei Zinovyev and Petr Schastlivy are all over 30.  In fact, the names of all their forwards are familiar to international and NHL fans:  Robert Nilsson , Alexander Svitov, Oleg Saprykin and Jakub Klepis round out the group, all former NHL players.

For Atlant, their veteran roster, with only one of their top six D under the age of 30 (and no top forwards under 30, either), this might be their one shot at a championship.  The team has never won either a Russian Superleague title or the Gagarin Cup, and for players like former NHLer Oleg Petrov, this is probably the last shot at the KHL's top prize.  The team got three extra days rest by winning their Conference Final in six games, and they probably needed to use it.  Atlant does have younger regulars on their roster, but they generally only play a few shifts per game, if that. 

The low event style of game for Atlant probably suits them well, but I don't know how they can manage to keep up against Ufa's speed, skill, and depth.  There is no advantage to be seen in goal, with Erik Ersberg and Konstantin Barulin posting almost identical numbers, and even in terms of recent playoff experience Ufa has them beat.  Luckily for Atlant, Ufa isn't that far away from the Moscow region, so travel shouldn't play a major role. 

I'm predicting that Ufa, winners of the last Superleague title back in 2008, will become the second team to win the Gagarin Cup, and will prevail in five games.  They have a seriously well built team that would honestly compete in the NHL.  They represent the potential of the league, while Atlant represents closer to the reality, as a team full of players who played themselves out of the NHL. 

• Atlant @ Ufa, Friday Apr 8 (3:00 PM CET/10:00 PM EST)
• Atlant @ Ufa, Sunday Apr 10 (1:00 PM CET/8:00 AM EST)
• Ufa @ Atlant, Tuesday Apr 12 (5:30 PM CET/12:30 PM EST)
• Ufa @ Atlant, Thursday Apr 14 (5:30 PM CET/12:30 PM EST)

Games 5-7 are as yet unscheduled, but every second day is the KHL standard, so expect Game 5 to be on Saturday, like an early start.

Safety innovation grant allows professor to develop life-saving technology

Jeremy Seidt, a research associate professor within The Ohio State University’s Department of Mechanical and Aerospace Engineering, was awarded a Workforce Safety Innovation Grant through the Ohio Bureau of Workers’ Compensation (BWC) for his Proof-of-Concept Project.

Seidt’s project is an Oxygen Concentrating Self-Rescuer (OCSR)—a personal, wearable air purifier that uses an innovative circuit of chemical and physical filters to sieve and contain oxygen from the environment, remove any toxic gases, and leave its users with breathable air.

Inspired by decades of coal mining tragedies, Seidt designed the OCSR to filter out methane and carbon monoxide—the latter of which is a great concern for miners, who can sometimes become trapped underground in carbon monoxide-rich environments due to methane explosions.

Miners typically carry Self-Contained Self-Rescuers (SCSRs), belt-wearable devices that contain a chemical, solid O2 that reacts to create gaseous, breathable O2.

“SCSRs have a finite operational life,” Seidt explained. “Once ignited, the O2 reaction lasts about 30 to 60 minutes, depending on the model.  If the worker can’t escape in that limited amount of time, they will likely die.”

Seidt continued that such injuries are not caused by a lack of oxygen, as there is already plenty of oxygen available in the air, but by exposure to noxious gases that co-occur.

Seidt’s innovation seeks to supply workers the air they need, not by bringing in an external oxygen supply such as a SCSR or an oxygen tank, but by pumping air through the OCSR’s maze-like circuit of molecular and electrolytic sieves and catalyzing zeolite bed, which collect the oxygen already present and remove any unwanted gases.

With a greater supply of filterable air available than the amount of oxygen one SCSR can hold, the OCSR seeks to give trapped miners—and workers in fields such as firefighting, Homeland Security, and the Department of Defense—the time they need to complete their tasks and escape to safety.

Seidt believes that the device, with modifications, could have significant implications specifically for firefighting.

“We believe that this device will be transformative for both structural and wildland firefighters,” Seidt said. “We expect the OCSR to weigh about half that of a Self-Contained Breathing Apparatus (SCBA) oxygen tank, meaning that firefighters will be more likely to use it in a smoldering, post-fire environment.  This will reduce respiratory ailments such as lung cancer in these workers.”

“Wildland firefighters typically use no respiratory protection since they must traverse long distances and rugged terrain.  A lighter OCSR device could bring basic respiratory protection to this workforce.” Siedt said.

The BWC’s Workforce Innovation Grants are a total of $5 million awards given to those creating innovations that improve workplace health and safety. Two Proof-of-Concept Projects grants and three Prototype Projects grants were awarded to individuals from various research organizations across the state. Seidt was awarded over $500,000 to test the OCSR concept.

Being a recipient of the award not only allows Seidt to develop a potentially life-saving technology, but it allows The Ohio State University Engineering students the opportunity, as well.

“It’s been great working with Piyanadda (Ploy) Thipyapong (Aeronautical and Astronautical, Master of Science student) on this project. She’s been building the proof-of-concept gas separation apparatus and programming the control and data acquisition system. Her Master of Science thesis will be entirely based on this work,” Seidt explained. “Also, post-doctoral candidate in Materials Science and Engineering, Sedzro Tamakloe, is fabricating an O2 pump module that will be integrated in the device. Yahye Ahmed, aerospace engineering undergraduate student, has been supporting the project in materials acquisition and support for Ploy. It’s been a great team effort.”

Seidt and his team are working on the project with two industry partners, Energetic Systems and Zeovation, a company founded by a former professor at the University. Experiments to test the concept are ongoing.

“I’m looking forward to seeing Ploy’s first data sets. I believe that we’ll be successful in the proof-of-concept phase,” Seidt said. “Hopefully, we’ll receive funding next year for the Phase II effort to develop a prototype OCSR.  I’m optimistic this will be foundational work for truly transformative personal protection equipment.”
