pm on April 28, 2017. Tenders will be opened in the Safety Regulation Department meeting
room of the TTCAA Administration Building on April 28, 2017 at 3:00pm, in the presence of
tenderers' representatives who choose to attend.
This procurement process is not intended to create and shall not create a formal legally
binding bidding process and shall instead be governed by the law applicable to direct
commercial negotiations. For greater clarity and without limitation:
1. The RFP/Tender shall not give rise to any "Contract A"-based tendering law duties
or any other legal obligations arising out of any process contract or collateral
2. Neither the Tenderer nor TTCAA shall have the right to make any breach of
Contract, tort or any other claims against the other with respect to the award of a
contract, failure to award contract or failure to honor a response to the RFP/Tender.
The TTCAA reserves the right to reject or accept any tender and is not bound to give
reasons for its decision. Late tenders will not be accepted.
The TTCAA also reserves the right to cancel the bidding process in its entirety or
partially without defraying any cost incurred by any tenderer in submitting or preparing
to submit a tender.

uses thoughts to
control arm and hand
A paralyzed man has regained the use of his arm
and hand using a system that decodes his thoughts
and controls his muscles.
"I thought about moving my arm and I could move
it," says Bill Kochevar, 56. "I ate a pretzel, I drank water,"
he says in a video produced by Case Western Reserve
University in Cleveland.
Kochevar was paralyzed in a bicycle accident when he
was in his 40s. And for the next eight years, he was unable
to move any part of his body below his shoulders. The
damage to his spine meant signals from his brain had
no way to reach those distant muscles.
Then researchers offered Kochevar a chance to try an
experimental system called BrainGate2. The effort to
restore movement to his arm and hand is described in
The Lancet. It involved Case Western, the Cleveland VA
Medical Center and University Hospitals Cleveland Med-
ical Center. The idea was to create a new connection be-
tween Kochevar's brain and his right arm and hand. First,
surgeons implanted two electrode arrays in Kochevar's
brain. The electrodes detect signals coming from areas
of his brain that once controlled his right hand and arm.
"We have an algorithm that sort of transforms those
neural signals into the movements he intended to make,"
says Robert Kirsch, a professor of biomedical engineering
at Case Western. But movement requires muscles. So
doctors also implanted electrodes in muscles that control
his arm and hand movements.
The final result was a system that could determine
which movements Kochevar wanted to perform, then
electrically stimulate the appropriate muscles in his arm.
When he's connected to the system, Kochevar can extend
his arm and grasp things with his hand, the researchers
report in The Lancet. He's even found a way to scratch
his nose. A previous effort in a different paralyzed patient
restored only hand movement. And several teams have
used brain interfaces to let patients control robotic arms.
The system Kochevar uses has taken scientists more than a
decade to develop. Yet it's still limited to research labs and
depends on wires that penetrate the skull and skin, Kirsch
says. "I think what we've done, though, is shown that we
can put this all together and it's feasible," Kirsch says.
"We can actually record signals from his brain, de-
termine what he's trying to do and make that happen."
For Kochevar, this is a big deal. "I'm still wowed every
time I do something," he says. "Amazing." (NPR)
Heroin use, addiction up sharply
among US whites, says study
Heroin use in the United States has risen five-
fold in the past decade and dependence on the
drug has more than tripled, with the biggestjumps
amongwhites andmen withlow incomes andlittle
education, researchers said on Wednesday.
Whites aged 18 to 44 accounted for the biggest rise
in heroin addiction, which has been fueled in part by
the misuse of opioid prescription drugs.
The findings are troubling because the people most
affected have few resources to deal with the problem,
said Dr Silvia Martins, an associate professor of epi-
demiology at Columbia University Mailman School of
Public Health, and her colleagues. "We are seeing that
heroin use has increased in the past 10 years," Martins
said in a phone interview.
"It is more prominent among whites with lower in-
comes and education and young adults."
Heroin use, which includes those who have tried the
drug but not become dependent on it, and addiction
also rose more among unmarried adults. Although a
jump was seen among women, it was not as prominent
as for men.
The researchers found no differences in heroin use
or addiction among the major regions of the country.
The findings, published online in the journal JAMA
Psychiatry, followed a statement from the American
College of Physicians calling for drug addiction and sub-
stance abuse disorders to be treated as a chronic medical
condition like diabetes or hypertension. (Reuters)
