Viscosity

been around since “Rudolf Diesel first invented the diesel engine, and showed it at the 1900 Paris World's Fair, running on peanut oil” (West, 2004). Additionally, technology has come a long way in changing the properties and viscosity of biodiesel. This reduction in viscosity increases the ability of the engine to use it without any negative side effects (Balat, M., Balat, H., 2008). Just a little research will show the potential and many qualities biodiesel…

Respiratory Failure Respiratory failure is a deterioration of the gas exchange function of the lungs (Hinkle & Cheever, 2014). The lungs are not able to provide adequate oxygenation or ventilation for the blood. Respiratory failure is caused by impaired ventilation or perfusion mechanism in the lungs. Colon Cancer Colon cancer arises from the epithelial lining of the intestine. It may start as a benign polyp and become malignant. “It will invade and destroy normal tissue and extend into…

i. Yes ii. Yes iii. Yes iv. Yes (The lesson provide students with the opportunity to measure the thickness of the slime and compare it thickness to viscosity of fluid.) v. Yes.  Students gather to discus design and make open inquiry about the slime lab experiment using the internet. A. Yes, practices, disciplinary core ideas, and crosscutting concepts and building on students’ prior knowledge are evident in the lesson plan.  Administer a Pre-Test to guage student’s past experience in orther…

the high demands and unmet needs for the organs worldwide, making the biomaterials will allow the other companies to the faster printing of the tissues. It is a time-consuming process and these hydrogels have specific requirements related to the viscosity and the gelling speed. So we, at Bioriginate in collaboration with…

Shortage of the organs and tissues has always been a critical medical problem. According to the data from Health Resources and Services Administration, US Department of Health and Human Services, the patient waiting list for organs in US consists of more than 80,000 patients and many of them die waiting on their organ list. There are several approaches for addressing this problem like artificial organs, xenotransplantation, etc. But these have other limitations like expensive organ- transplant…

However, when the results were compared, tack values were affected more by the temperature than by speed (friction) itself. In the results portrayed above, when the Inkometer was set at 90 degrees Fahrenheit, 800 RPM, the initial tack value measured at 1 minute was 8.2, as opposed to 10.4 when the speed increased to 1200 RPM. Furthermore, when the same results were compared to that of 100 degrees Fahrenheit, both 800 RPM and 1200 RPM, tack values taken at 1 minute had marginal differences, 7.0…

The difficulty of mining oil sands varies depending on the location of the oil sands. Oil sands deposits that are less than about 250 feet below the surface can be removed using conventional strip-mining methods. The strip-mining process includes removal of the overburden, excavation of the resource, and transportation to a processing facility. Nearly all mined bitumen is currently upgraded to synthetic crude oil. Oil sands extraction processes are generally divided into two categories: mining…

The Yasur volcano is perched on a 1,184 foot high pinnacle overlooking Vanuatu. Every half hour, broiling geysers of basalt spew through its cauldron, a regular geological event that has been normal for centuries. Tourists find this easily accessible archipelago one of the safest and fastest ways to observe the colossal power of volcanoes, since it rarely has dangerous eruptions and can be accessed by vehicles. The primary means of transportation across the island’s dirt roads is by truck, and…

After entering the museum space, I quickly discovered that the Shrem Museum has many strict rules. I was told that I couldn't use pens and that I couldn't take pictures of certain pieces; therefore, I felt a little unwelcomed by the staff. However, the museum space was very open, light, and inviting. The video installation, Hoof & Foot: A Field Study, by Chris Sollars evoked many thoughts, as well as confusion. I could identify that the video drew parallels between animals and humans, and I…

Fluid dynamics relating to bluff bodies, non-streamlined structures or streamlined bodies at large angles of attack, remains a critical focus of study within the fluid mechanics community. One particular area of interests involves the occurrence of fluid-induced vibrations, or more commonly known as vortex-induced vibrations (VIV’s), exerted on bluff bodies. Due to the production of vortex shedding beyond bluff cross sections, an alternating pressure distribution produces periodic fluctuations…
