Central Artery: The Big Dig

Like normal roads, the National Road began to deteriorate over time and because of that, the federal government stopped funding the road and it was abandoned at Vandalia, IL for “political and practical reasons”. Originally the plans called for it to stretch from Baltimore to St. Louis but the rapid growth of railroads led to the project being abandoned. Even though it never quite reached the final goal, it did eventually stretch 800 miles. Now, present day National Road is now part of U.S. Route 40. Roads today are either under construction or in need of construction. In the year 1811, Washington and Jefferson advocated on the idea to aid western expansion, so work on the “National Road” or “Cumberland Road”. This is the first road that was surveyed by Congress in 1806-7 and built from 1811-37. This road branched from the Cumberland, MD. In order to create this massive road, it had to under very crucial

I found the differences between arteries and veins are their functions they provide to the heart as well as their structure. Arteries transfers blood away from the heart into the periphery resulting in the pressure of the blood in the arteries being high. Where as, the veins transfer blood towards the heart. Arteries carry oxygenated blood distributing it in the periphery as the pulmonary artery moves deoxygenated blood into the lungs for purification. The wall of an artery consists of three layers machining it thicker than veins. The elasticity within the layers of the muscle allows arteries to handle great pressures of blood within it. The thickest layer is known as tunica media as the other two are recognized as tunica externa, and tunica interna. The vein obtains blood from the periphery and carries it towards the heart. Veins are known to carry deoxygenated blood and transfers it the heart for purification. The pulmonary vein is known to carry oxygenated blood. However, there are semilunar valves found within the vein that does not allow retrograde flow of blood in preventing blood to flow in the opposite direction. Veins are thinner when compared to arteries consisting of thin elastic muscle layers with one thick layer being the tunica adventitia. Arteries consist of: carrying oxygenated blood expect for the pulmonary artery; deeply found in the body; thick walled and

With the constrained scenario, traffic flow has improved, commute time has decreased, workers are getting to their places of business faster, and the businesses themselves are finding that they can transport their goods in a more timely fashion. The measures that were employed consist of adding directional bike lanes to the bridge, restriping the bridge combined with timed directional transition of the middle 5th lane, additional bus routes, and converting old buildings into domiciles. Although these measures have helped to improve traffic flow in the region, capital will have to be spent at a future date in order to add additional

The diagnostic process for a formally diagnosing Cerebral Vascular Accident (CVA/stroke), would consist with a number of test including a physical exam and questions regarding your family history of strokes, any signs or symptoms that may have been present before the patient had the stroke. The physician would also order a few tests like a MRI, CT scan, Cerebral Carotid ultrasound, Cerebral Angiogram and an Echo Cardiogram. The physical exam is important to listen to the hearts sounds, take your blood pressure and also use a ophthalmoscope ( a scope to look in your eyes, ears and nose) to see if there are any cholesterol crystals behind the eyes("Diagnosis - Stroke - Mayo Clinic," 2015). A MRI, uses radio and magnetic waves to show a detailed

The project represents a $12 million investment, which is part of an overall $100 million infrastructure investment in roads and bridges throughout the city over the next ten years. After much initial groundwork securing funding and developing plans, the Evergreen Road Improvement Project officially began in June of 2014. The Project involved the total reconstruction of a one-mile segment of Evergreen Road between 10 and 11 Mile from the previous six and seven lane road into a four-lane boulevard with a roundabout at Evergreen and Civic Center Drive and a roundabout at Evergreen and the north Municipal Campus

Purpose / Justification: The purpose of this project is to provide a roadway link across SR-55; support circulation between

There has always been a demand for roads in the United States as roads are essential in the development of a nation. The national interstate highway system was America’s solution for the need of a road system that would stretch from coast to coast. The United States Interstate Highway System is a landmark project and often considered one of the greatest public works projects in American history by making travel by automobile faster, cheaper, safer and more convenient. New roads have been a necessity on our country ever since Henry Ford began to produce the automobile back in in 1903.

In Illinois, Route 66 ran through a densely populated area. Illinois had considerable infrastructure, including modern road systems. When Route 66 was officially commission, it took over U.S. State Route 4, which was a pre-existing road that was already a paved, two-lane road between Chicago and St,Louis. Because of Illinois’ population and development pressure, Route 66 was constantly doing repairs, resurfacing, and rerouting the road. The original idea was try and bypass as many rural towns as possible to prevent traffic, but with the growing cities, this would prove to be a difficult

The construction of the highway was approved in 1949 by an act of Canada’s Parliament and the construction occurred in the 1950s until it officially opened in 1962.⁸ After the opening of the highway it was extremely beneficial to Canada’s economy because it allowed Canada’s abundant natural resources to be shipped across the world. Both mega-projects were found as very beneficial to Canada in many ways including easy transportation and world

Since the early stages, the project was inundated with concerns and issues with the project scope. From the perspective of project management, the initial scope was not defined well enough. Details of the design were over looked and aspects such as the details of the air conditioning ended up increasing the original scope by $200 million. This supposedly led a prosperous project to an uncertain economic ordeal. Initial estimates of the project had been $5.5 billion and by the time of its actual completion it been delayed by a year and increased to $15

The project did not achieve desirable standards as far as customer requirements, scope, environment and execution were concerned. It was important that the project integrators to ensure customers do not escalate during the implementation of the project, being the first adopters of the software FoxMeyer should have exercised caution by adopting the software in phases rather than implementing the project directly, furthermore, execution was the biggest problem, despite knowing that the project needed skilled personnel FoxMeyer did not train staff during the early stages of the project and had to rely on consultants. Finally the company should have gained control over the project from the start to ensure that all the staff and management were involved but in this case despite knowing that the project would not work as envisaged the management did not take control or stop the implementation of the project.

Arterial remodelling is already observed in patients at the start of renal replacement therapy and is comparable in patients on peritoneal dialysis and patients treated by hemoidialysis. This suggests that non-hemodynamic factors could play an important role in the pathoiphysiology of vascular complications. As shown experimentally, the endothelium influences the mechanical and geometric properties of large arteries, and removing the endothelium causes an increase in arterial diameter (Levy et al., 1990). Endothelial function is altered in ESRD patients (Joannides et al., 1997) (Gris et al., 1994) (Van Guldener et al., 1998), and these alterations are associated with arterial

*A lack of efficient and effective communication between the city, project management team, and consultants. This manifests itself in basic issues like vendors blocking roadways for other vendors, the city canceling orders for electrical filtering components that were critical path, and too many unilateral decision made because "no one was in charge".

I wanted to meet with you in regards to my Vascular Exam that I took last week. I have been putting in a lot of effort by studying and coming into open lab and feel as though my work is not reflecting my grade. Unfortunately last Tuesday I was unable to take the exam due to the fact that I had a stomach virus and fever. Monday night I was hospitalized and put on IV fluids and medication. Once I contacted Professor Yarbrough about this matter she said that I could take the exam Wednesday, which I did. I am reaching out to you because most of my classmates informed me that the exam was scaled and everyone was given 6 extra points, besides myself. I am finding this situation very unreasonable due to the fact that my grade is in jeopardy and also

There are various factors that led to the fail of the perfect partnership. The project was very challenging with tight deadlines, which both parties hoped would “bring the best out of all concerned “ 1. They did not account for the downside. The project management team was taking a longer than expected duration to finalize the contract terms, which was diverting
