...Mechanical Engineers Mechanical Engineers are often what people picture when they hear the word engineer. This is partly because mechanical engineering is known as the engineering discipline with the broadest applications. Whether it is roller coasters, car engines, or computer keyboards, it is likely that a mechanical engineer was involved in its design. To be more specific, mechanical engineers work with any process involving moving parts. This includes the motor that pulls the rollercoaster car up track, the axles that allow cars to drive down the road and so much more. Mechanical engineers design every part of the piece of machinery so that it can perform the intended task efficiently. Performing tests to calculate how large a piston in an engine needs to be to produce a certain amount of power is one example of a task that may be assigned to a mechanical engineer. One notable innovation in the automotive industry is the Tesla Model S sedan, one of a few successful electric cars in the past few years. Featuring a range of over 200 miles and the handling of a sport sedan, the electric Model S is able to outperform its gasoline powered rivals in many ways. One notable area is safety. The mechanical engineers designed the frame so that it received a near perfect score in every crash safety test conducted by the National Highway Traffic and Safety Association (See Figure 1). This has set a new standard for not only electric vehicles, but all vehicles to ensure safety in the...

...Running head: ACCOUNTABILITY OF NURSING PROFESSIONALS: WEANING Accountability of Nursing Professionals: Weaning from Mechanical Ventilation Samantha Madrid Grand Canyon University Abstract This paper will discuss the weaning of patients off of a mechanical ventilator. It will look at the problems associated with prolonged intubation vs. premature extubation, and what healthcare professionals can do to assess a patients readiness to begin the weaning process. A patient care scenario will be given and an explanation of how nursing practice can evolve with the knowledge from this study will be shown. The accountability of the nursing professional in regards to mechanical ventilation will be visited as well. Accountability of Nursing Professionals: Weaning from Mechanical Ventilation “Mechanical ventilation refers to the use of life-support technology to perform the work of breathing for patients who are unable to do so on their own.” This is the definition of mechanical ventilation according to Cook, Meade, and Guyatt (2000). They performed a study to determine the optimal time to wean a patient off of mechanical ventilation. When weaning a patient you have to find the right time to extubate. Prolonged mechanical ventilation can lead to nosocomial pneumonia, cardiac associated morbidity, and possible death. However, extubating a patient too soon may result in having to reintubate which can result in the same illnesses as prolonged intubation. “Research to date suggests...

...Mechanical ventilation provides healthcare workers with a life-saving means of support for patients with various conditions and situations, such as sepsis or surgery. Although mechanical ventilation (MV) is life-saving it can cause damage if not managed well. For example, unnecessary prolonged MV can cause lung damage, infection and diaphragmatic dysfunction (Carl & Loik, 2012). Guidelines are statements intended to be used by clinicians as evidence-based references, to make their own judgments and decisions on a specific clinical situation (Haas & Loik, 2012). The objective of this specific guideline that this paper will review is providing evidence for weaning or discontinuing the mechanical ventilator. The purpose of implementing a guideline...

...Mechanical Engineers Qualities for Millennium 3 1) Bachelor’s Degree/Diploma in Mechanical Engineering or its equivalent. The mechanical engineer has been called the general practitioner and the jack-of-all trades among engineering professions. This is because he requires education and skills that span a broad range of technical, social, environmental, and economic problems. In general, however, the mechanical engineer is concerned with controlling the principles of motion, energy, and force through mechanical solutions. A mechanical engineer designs the tools and processes used for satisfying the needs of society through a combination of material, human, and economic resources. He might work on electric generators, internal combustion engines, steam and gas turbines, and other power-generating machines. He might also develop machines such as refrigeration and air-conditioning equipment, power tools, and other power-using machines. Engineers must combine a good understanding of science, mathematics, and computers with a good knowledge of current technology. At the high school level, the emphasis is on mathematics. Two years of algebra plus courses in geometry and trigonometry generally are required. In addition to the sciences and math, engineers need good communication skills, so don't neglect the liberal arts and humanities. In addition, remember that many of the large industrial firms that employ mechanical engineers are multinational...

...Automated Swell Index Measurements of Films Using THERMO MECHANICAL ANALYZER (TMA) SWAYAJITH SAHADEVAN swayajith@gmail.com Abstract Dimensional instability on finished plastics products due to changes in humidity is one of the leading causes of product failure. The test lead times associated with measuring changes in dimensions due to humidity changes are prohibitively longer & lot of machine time is consumed in the process. This can become a limiting scenario wherein multiple materials are scaled up for measurements or multiple formulation variables are being analyzed. In this paper, we propose to use the “Swell Index” as the prime factor to be used for evaluating the changes in dimensions. Swell Index of a material is defined as the ratio of difference in dimension to the original dimension as a function of temperature or humidity and is expressed as percent swell index (temperature) or percent swell index (Humidity) respectively. Swell Index is measured using TMA by measuring the dimensional changes as a function of time while cycling the environment of the test sample between dry Nitrogen (~0% RH) and wet nitrogen (100% RH). This analysis can be accomplished using few grams of samples without manual intervention, thereby leading to significant reduction in test lead times. Key words: -Thermo Mechanical Analysis, Swell Index, Dimensional stability Principle When hygroscopic polymeric materials experience humidity, the dimension of the material changes .The dimension...

...A computational study of three-dimensional turbulent flow and heat transfer was performed in four types of rotating channels. The first type is a rotating rectangular channel with V-shaped ribs. The channel aspect ratio (AR) is 4:1, the rib height-to-hydraulic diameter ratio (e/Dh) is 0.078 and the rib pitch-to-height ratio (P/e) is 10. The rotation number and inlet coolant-to-wall density ratio were varied from 0.0 to 0.28 and from 0.122 to 0.40, respectively, while the Reynolds number was varied from 10,000 to 500,000. Three channel orientations (90 degrees, −135 degrees, and 135 degrees from the rotation direction) were also investigated. The second type is a rotating rectangular channel with staggered arrays of pinfins. The channel aspect ratio (AR) is 4:1, the pin length-to-diameter ratio is 2.0, and the pin spacing-to-diameter ratio is 2.0 in both the stream-wise and span-wise directions. The rotation number and inlet coolant-to-wall density ratio varied from 0.0 to 0.28 and from 0.122 to 0.20, respectively, while the Reynolds number varied from 10,000 to iv 100,000. For the rotating cases, the rectangular channel was oriented at 150 degrees with respect to the plane of rotation. In the rotating two-pass rectangular channel with 45-degree rib turbulators, three channels with different aspect ratios (AR=1:1; AR=1:2; AR=1:4) were investigated. Detailed predictions of mean velocity, mean temperature, and Nusselt number for two Reynolds numbers (Re=10,000...
