A 45 year old male presents with a three day history of persistent headache, described as a dull pressure sensation across his forehead. He reports no recent head trauma or changes in vision. Additionally, he mentions feeling fatigued and experiencing mild nausea. No recent illnesses or medication changes are reported. Further inquiry into stressors and recent lifestyle modifications is needed to understand the potential triggers and contributing factors.

C. Seeman and William B. Sherman of New York University recently made such an announcement, however, it earned coverage in several scientific journals. The attention had to
do with the new walker's size, which is very small for its age-or any age. A pair of legs and feet constructed from DNA strands, the walker stands just 10 nanometers tall-or roughly 1/25,000
the diameter of the period that concludes this sentence. Seeman says the walker's stroll along a DNA sidewalk is "a natural outgrowth of work that's been done before. Seeman and Sherman, who christened their pride and joy A Precisely Controlled DNA Biped Walking Device, make
clear that the walker has no practical application. And even, though he calls it "the robot, Seeman seems wary of characterizing it as a harbinger of submicroscopic automation. He does, however, see the possibility of some practical uses. "We're going to look at longer sidewalks," he says. "Eventually we might have it try to carry a load. We'll probably also look into using it for
polymer deformation-maybe using circular sidewalks and have them holding strands and twisting or braiding them." Bragging rights and applications aside, Seeman sees the walker as
one more event in an accelerating series that is transforming nanotechnology from science
fiction to science fact-developments that are making nanotechnology a very exciting field to be in right now. "I figured out this was going to be fun in 1980," Seeman says. "Now that I've been working in this area for nearly a quarter of a century, it's really starting to snowball."
Nanotechnology-engineering at the molecular level to create useful substances and devices-is no longer just the stuff of rumour and futuristic visions. It has begun to spawn viable businesses and useful products, and it's already touching our lives in many ways Nanotech products may
be found in the car you drive and in the paint on your walls. They are enhancing medical diagnostics, improving the composition of building materials and plastics, and paving the way
for radical breakthroughs in electronics and computer technology. Make no mistake: Engineering on very small scales is a very big deal The Nano Business Alliance, an industry trade
organization, predicts a global market for nanotech products and services of $1 trillion by 2010. The National Science Foundation forecasts that the market in the U.S. alone will reach $1 trillion
by 2016. Most U.S. states have established programs or agencies to encourage nanotechnology research and business development. And the federal government, characterizing nanotechnology.

Naloxone Hydrochloride (NARCAN) Class: Opioid Antagonist Dose: • 0.5-2mg dependent on route Route: Intranasal via preload/ MAD device or IM Action: Reverses respiratory depression, sedation, and hypotensive effects of opioid overdose by occupying opiate receptor sites. Onset: IN: 1-2 minutes, IM: 2-5 minutes Duration: IN: 30-60 minutes, IM: Longer Indication: Respiratory depression / respiratory arrest with a suspected narcotic overdose with CNS depression, hypotension, or bradycardia Contraindication: None Special Information: The duration of Narcan is generally less than any opioid. Watch for relapse as long as opioid is still in the patient’s system and be prepared to continue administration
Common law governs all contract disputes unless otherwise governed by the statute. Therefore, the most efficient way to determine what law governs is to conduct a statutory scope analysis.
My approach to answering these disputes is the analytical framework. I will begin with (1) what law govern. (2) after determining what law governs, I will now look for was a contract formed. (3) Having determined that a contract was formed, I will now look for defenses, (4) Having determined that there are no defenses that block the enforcement of the contract, I will now look for what are the terms of the contract. (5) Having determined the terms of the contract, I will now look for a breach, (6) Having determined that there is a breach, are there any legal excuses that forgive that breach, (7) Having determined that there no legal excuses that forgive, what are the remedies, (8) Having determined that there are remedies, I will now look for alternative remedies.
