Modeling Blood Flow Heart Pumps

Modeling Blood Flow Heart Pumps Modeling Blood Flow Heart Pumps Blood and water they may both be aufgetauts, but blood, a complex flow, contains solid platelets flowing within liquid plasma. The mix of solid with liquid spells the difference between a fluid flow easily simulated on desktop computational fluid dynamics (CFD) software and a flow analysis on a powerful supercomputer.Blood coursing through arteries contains both solidsplateletsand liquids, making for a fluid flow that cannot be simulated very easily.Although a number ofCFD vendors sell desktop software that helps model complex flows, most flows are rather difficult and many are impossible to model. Typically, more than one type of force acts on the complex fluids, or they contain a mix of solids and liquids. To be solved, they need supercomputer power, according to Marek Behr, researcher and chair for computational analysis of technical systems at RWTH Aachen University in Germany. Behr and a colleague, Matteo Pasquali, in the Department of Chemical and Biomolecular Engineering at Rice University, Houston, TX, are now at work writing a CFD application that will help a heart-pump manufacturer analyze how blood would move through different pump configurations.Modeling ChallengesModeling blood flow in rotors is a huge problem. The solution needs to account for time, fluids, and solids, and bring in elements concerned with both the chemistry and biology of the fluid.In blood, about half the volume is red blood cells, Pasquali said. You can think about them as dropletsalthough theyre flat when at rest, surrounded by plasma thats like water. Having those droplets as 50% of the volume makes blood behave in a way thats different from the way water or air would behave.According to Behr, Classic mechanical engineering materials dont have a timescale. Water doesnt. But blood has all these capsules and droplets that can be stretched. The timescale is the time it takes for one of these blood cells to relax back to its shape once its stretched.He adds that CFD programs that depict blood damage usually depict blood cells that stretch rather than break because stretching is easier to analyze for.But, if a pump rotor were to shear droplets, hemoglobin could be freed from the cells and leak into the plasma. At a particular mix, that hemoglobin in the plasma becomes toxic to the patient. Applications that analyze shear are very important to pump designers. They would like to predict how much hemoglobin would leak out when blood flows through a centrifugal rotor to keep shear below a toxic level.You have to design a pump that pumps enough blood within its small footprint but doesnt damage the blood cell, Behr says. You need the pump to be small because its in your body. But it pumps several liters a minutethe heart pumps five liters a minuteand that amount of flow in a device that small makes for a great shear rate.Helping Scale for Child-Sized PumpsHeart pump maker Micromed Cardiovascular, Inc. , Houston, TX, approached Behr and Pasquali to collaborate on an analysis program to depict blood shear around a rotor in an axial pump that could help them analyze and scale pump flow to a size suitable for children.Theyve turned to the universitys Cray XD 1 supercomputer to compute what Behr called a very computer-intensive problem, the largest hes ever run. Its an equation with five mio unknowns, Behr says.The geometry of the pump is quite complicated and it has to be analyzed for flow and time. For example, the actual pump has no flow before the rotors start turning. It takes about five 5 or 10 revolutions after blood flow starts before that flow is quasi-steady.In real life, that takes a fraction of a second, Behr says. Depicting those 5 to 10 revolutions for analysis takes 10 supercomputer hours.They understand the importance of their task for the children who will need these pumps. Pasquali envisions that maybe someday a doctor could look at a patient, run a number of tests, and give specifications based on those tests to create a pump appropriate for a person of that size and age. So despite the difficulty of the problem, they push onward, knowing that many of the things we take for granted today were once impossible, too.Adapted from Modeling Blood Flow for Heart Pumps, by Jean Thilmany, Associate Editor, Mechanical Engineering, April 2006.The solution for modeling blood flow in rotors needs to account for time, fluids, and solids, and bring in elements concerned with both the chemistry and biology of the fluid.

Job Titles [2019] - Examples for Your Resume & Job Search

Job Titles 2019 - Examples for Your Resume & Job SearchJob Titles s for Your Resume & Job SearchBest Practices for Professional Job Titles on a Resume (+Examples)Have you been taking professional titles for granted?Youre not alone. A lot of job searchers pay too little attention to these small bits of content. But what if I told you that your chances of being interviewed depend on the professional titles you use, both in your resume summary and in describing your employment history?Most people think that they should automatically jot down current and past job titles that employers have given them. False.Writing targeted professional job titles is an essential step in resume writing. Let me elaborate.What is a job title?A job title is a specific designation of a post within an organization, normally associated with a job description that details the tasks and responsabilities that go with it. Source.Professional Job Titles for Resume SummariesThe first instance that requires you to w rite a professional resume title is at the very top of your resume, in your resume summary. Bear in mind that this will be the first thing that someone will look at when reading your resume. So it had better make a good first impression.List of General Job Titles Most PopularAdministrative AssistantExecutive AssistantMarketing ManagerCustomer Service RepresentativeNurse PractitionerSoftware EngineerSales ManagerData Entry ClerkOffice AssistantYour opening professional title should follow two guidelines 1) It needs to grab recruiters attention 2) It needs to include keywords for an Applicant Tracking System (ATS).The easiest way to ensure that you are giving recruiters and ATSs what they want is to match your professional title with that of the prospective job. For example, if a company is hiring a Project Manager then you can just follow their lead and use this as your title.Of course, you might feel like copying the prospective job title is boring. Some companies deliberately ask f or creative applications from candidates, which makes you feel like you need to up your game and develop something more catchy.The advice here is to not overthink the professional title. Keep in mind that you can use a few lines in your resume summary to let your personality and creativity shine through.If you decide to diverge from the job title provided by the employer, be sure to use industry-related terms that will be common to recruiters. Such language will not only be familiar to recruiters, proving you understand their needs, any ATS will also recognize these as keywords, helping you get past an initial automated screening.Common Mistakes in Resume Professional Job TitlesToo long (keep it to 4 words max.)Using jargon (use recognized industry terms)Using superlatives/adjectives (avoid words like greatest, best, etc.)
