Letting students participate in science competitions has always been a good way to promote learning. And some institutes have taken the contemporary notion of competition to the next level by bringing in initiatives such as the International Genetically Engineered Machines (iGEM) competition. This year, the version had many projects related to synthetic biology; the concept at this level is to design, build and test genetically engineered organisms. A lot of these have a direct link to biomedical engineering. For instance, one project focused on engineering gene circuits in a model organism of yeast to better understand how cells make their decisions. These circuits may very well be used in future bio-manufacturing. Projects such as these fall in integrative science and students can be reared for such learning through online education. Not only are there a massive number of tools, but hands-on tutorials can also serve as a good guiding template for the student.
Did you see the new Goldie Blox video? This company, whose tagline is “toys for future engineers,” just released a viral video in which three young girl engineers execute a Rube Goldberg machine set to the tune of the Beastie Boys’ “Girls.” This video is excellent because it helps draw young girls’ attention to the possibilities of engineering. Maybe after seeing the video, they’ll ask their parents for a Goldie Blox kit or try to build a Rube Goldberg machine in their living room. Maybe they’ll learn, as all engineers do, that a successful project means educating yourself in math and physics; that you need to know exactly how far apart to place each domino to make sure your train falls at an even, consistent rate.
Your essay will be one in a large stack given to a reader or readers after you submit it. In the case of college admissions, readers will have so many essays to read that they will spend only a few minutes on each. Exit and SAT essays will receive somewhat more time and attention, but it still holds that one reader will be responsible for many essays. That is why it is imperative that you not only impress your reader(s) with your unique take on a topic but also say exactly what you mean as clearly and, in many cases, as concisely as you can. Your essay goal is to convey information, including the fact that you can write well. That goal won’t be achieved if your readers don’t understand your first few sentences or paragraphs and stop reading, or if they finish reading but fail to grasp your message. Learning how to be a clear and accurate writer will help make your essay readable and will guarantee that those who read it understand exactly what you mean to say. The five guidelines in this chapter show you how to clarify your writing. Suppose you are facing some problem in…
Touch screen technology has been on the market for a while now – specifically for gaming devices – although it’s only in the last 10 years that this translated to mobile technology. It has boosted online gaming numbers because of the ease of use on mobile phones, but how exactly has touch screen technology improved? The primary type of touch screen currently used in mobile technology (especially the iPhone) is a capacitive screen; these work with anything that holds an electrical charge – including human skin. They’re made up of materials that hold charges in an electrostatic grid of either a surface or projective screen. Resistive screens are analog devices that create a connection between two flexible resistive screens. They use your finger’s pressure to create a change in the flow of electricity; when a finger is placed on the mobile, a voltage drop is registered that allows the screen to work.
Who wants to spend their precious time? Everyone wants fast and efficient services from public services, especially in health and insurance areas. Instead of wasting your time in a long queue, you should use an electronic signature in healthcare. Yes, it is a fact that you do not have time to go to the hospital or insurance office to sign the documents. Therefore, do not be left behind. You will find and enjoy the benefits of having such a beneficial item. Besides saving your time and cutting the useless formal procedures, you also start the greener process—no need to print the papers anymore if you have online signature healthcare.
There are several top questions for a better understanding of e-signatures. These include the legality of e-signatures, the primary laws and regulations of e-signatures, the legality of handwritten signatures and e-signatures, and the integrity of e-signatures. Now, let’s talk about the legality of electronic signatures. E-signatures have already been made legal by the government. There are several points why e-signatures are used. The benefits of using electronic signatures include practicality and efficiency. In addition to that, it can also eliminate the use of papers. Electronic signatures are also important for the integrity of certain documents.
AVI (Audio-Video Interleaved) video format is a standard format around the internet. Windows introduced this format in 1992. AVI files carry audio and video data that are played synchronously. Audio and video can be compressed with different codecs and stored in a single .avi file. That can be played with Windows played or another player with the right codecs. If you are MAC used and carry the iPad around, you probably noticed a problem with playing AVI files on these devices. Apple is stuck to MP4 format, which actually is more advanced because it can carry more information than audio and video. 3D graphics, subtitles, and still images also can be packed along in a single file. All benefits and disadvantages you may find on the internet. The user may find a problem playing one or another format on his machine. As we mentioned, without unique apps, there can be a problem playing .avi files on the iPad. Instead of struggling to find one good AVI player probably, it is worth converting them to mp4. There are many video converters available to download. For instance, Aimersoft.com produces an excellent free video converter called Video Converter Ultimate. It supports all standard…
Have you ever played with a manually tuned induction heater before? If you did, then you must know that how dull it could be… Oh, for those that didn’t know what the induction heater is, that is a key piece of equipment used in all forms of induction heating. An induction heater will technically operate at either medium frequency (MF) or radiofrequency (RF) ranges. Three main components form the basis of a modern induction heater, such as the power unit (power inverter), the word head (transformer), and the coil (inductor). This project is slightly different from the regular induction heater driver, as it will include the Phase Lock Loop (PLL) into it. A phase lock loop is a control system that can generate a signal, and it has a fixed relation to the phase of a “reference” signal itself. Since the phase lock loop circuit responds to both the frequency and the input signals phase, it raises or lowers the frequency of a controlled oscillator automatically until it’s matched to the reference in both frequency and phase. Overall, this PLL induction heater driver will be one of the magnificent projects that you’ve ever built!
