Agglomerated materials are separated into uniform particles that are separated rapidly with sieving attachments. This high speed video clearly illustrates the dispersion of carbon black particles, their de-agglomeration, and progressive and comprehensive coating of the plastic pellets. Coating larger particles with smaller ones is a common processing application, and milling is often a part of the same process. Static and other physical forces combine to thoroughly coat particles, one material on another, layer upon layer. RAM can effectively mix both similar and dissimilar particle sizes and achieve a uniform final blend. RAM’s powder and solids mixing capabilities include: It causes them to divert their paths, collide and re-collide with other particles that are behaving in equally chaotic fashion to accomplish rapid and complete mixing. RAM’s unique sound-energy motion causes each powder particle to randomly collide with adjacent particles. In fact, RAM mixes solids 10+ times faster and more uniformly than traditional mixing methods. Powders of nearly any size, material characteristic, or morphology are rapidly and thoroughly mixed using RAM technology – including both free-flowing and cohesive powders. ResonantAcoustic® Mixing (RAM) is a game-changer for powder mixing. Thus, historically, a mixing technology has been selected based on the specific powder properties for a given mixture including flow characteristics and particle size. They are generally not capable of mixing both free-flowing and cohesive mixtures. RAM Powder Mixing Capabilitiesĭue to their mixing intensities and mechanisms, traditional mixing methods such as shear, diffusive, and convective are only effective at blending certain types of powder mixes. Additionally, larger powder particles may be dry-coated with a smaller particle to reduce interparticle forces and the tendency for aggregate formation. In many cases, cohesive powder mixtures require milling or sieving to break up the aggregates. In cohesive powders, the aggregates are clumps of the powder mixture that, if not dispersed properly, can lead to varied and uneven mixing in the vessel. To combat segregation, companies often minimize the time between the mixing step and the next step in the process, as well as implement special material handling processes.Īggregation is another issue, and often occurs with blending powders in cohesive mixtures. In many cases, larger particles segregate to the outside of the container while smaller particles remain closer to the center.Įach of these can occur anytime during the mixing step through transportation and storage of the material. Transportation occurs as the powder particles are jostled around during transport.Similar to percolation, vibration mostly occurs when powders being mixed include large and small particle sizes. Vibration occurs over time as smaller particles are vibrated and shift under larger particles.This form of segregation typically occurs when powder mixtures have a wider range of particle size. Percolation occurs when gravity pulls smaller particles into void spaces. Segregation typically occurs one of three ways: percolation, vibration, or transportation. Free-flowing powders are at a much higher risk of segregation compared to cohesive mixtures. Segregation, or demixing, is one of the biggest challenges in powder mixing. Additionally, the tendency of powders to be cohesive increases as particle size decreases in other words, smaller particles tend to be more cohesive while larger particles are more likely to be free-flowing. Several factors influence the formation of aggregates, such as moisture, electrostatic charges, and inter-particle forces. Free-flowing powders do not cling together, whereas cohesive powders stick to each other and form aggregates that do not disperse well during mixing. Powders can be grouped into two main categories based on flow properties: free-flowing and cohesive. Before diving deeper into the problems, it helps to have a basic understanding of powder flow characteristics. The main challenges with mixing powders are segregation and agglomeration, which are directly related to the flow characteristics and particle sizes of the powders in the mix. Powder mixing may seem simple, but is often complicated. The mixing step is crucial to many processes with the primary objective to achieve uniform distribution of all ingredients. Powder mixing is common in companies across many industries, including those in the pharmaceutical, advanced materials, and chemical sectors.

Support for artists and engineers!Ĭomputer-aided design systems for automating work with drawings, plans and other technical documents use vector graphics formats. They are ideal for advertising purposes: for souvenir mugs, T-shirts and badges, as well as for making plastic items. Vector images are used as a "map" by dedicated tools: plotters, machine tools with software control. For example, if a logo image is low quality and pixels are visible when enlarged, it can be converted into a vector object that can be scaled up to the desired size without losing sharpness. Vector graphics are mainly used in visual design. Such an image can be enlarged or reduced without loss of quality. Now, if we zoom the picture closely we can see that the edges look more realistic.It is a complex computational process that converts a raster image, consisting of pixels, into a vector image consisting of lines, curves, and other geometric shapes. You can also darken the remaining edge layer to minimize the blurring effect even further. Proceed to drag the layers you no longer need and delete them from the image. Now you can drag these unneeded layers out, delete them, etc. This should free every single layer which is part of the image. To Remove the extra layers, select the image and, on the top menu, click on “ Object” and “ Ungroup“. Since now we have a vectorized image and our edges are perfect, we no longer need some of these layers. However, since the edges were previously blurred, this blurring is now transformed into a number of layers that go from darker to lighter to simulate the blurring. When regular images are transformed into vector images, these pixelated edges no longer exist you can zoom the image to infinity and you will not see any distortion. If you zoom an image that is not vectorized, you will see that its edges tend to blur to blend-in with the environment this way they minimize the effect of the jagged pixelated edges. Drag the new image to one side, and delete the old image you no longer need. Now, a vectorized image is created on top of the original one in a new layer. You can leave Size, Threshold and Tolerance with its default values or play with them until you achieve the desired results. In the picture below, this option makes the background transparent as well as the belly and eyes of the penguin.ġ) Make sure “ Suppress Speckels” is selected.Ģ) Make sure “ Smooth Corners” is selected.ģ) Make sure “ Optimize Paths” is selected. One drawback of this option is that Inkscape will remove the background of the picture as well as any other part of the picture that has the same color. The following picture explains how you should configure the trace bitmap settings to achieve the best results.ġ) If you have a color image, like the one in our example, select “ Colors“.Ģ) Select “ Smooth” to make every border in the image as smooth as possible.ģ) Select “ Stack Scans” to create whole figure layers, which would blend nicely with the rest of the image otherwise inkscape will create white gaps between layers.Ĥ) (Optional) Select “ Remove Background” if you wish to make the image transparent. Then, on the top menu, click on “ Path” and then on “ Trace Bitmap…“. Go to the top menu and click on “ Path“, then “ Object to Path“.Īgain, click on the picture to select it. For our tutorial we are going to be using a jpeg image of the Linux Logo.Ĭlick on the picture to select it. There are a couple of problems with this. It does it with all other characters, adding them to the " base64" string, which will contain our final encoded text. Meaning base64chars is A, base64chars will retrieve B, etc. 29 th, because indexing starts with 0, not one. Simply put, our first Base64 number is 28, so it will use the 29 th character in the base64chars array, which is c. The same logic applies to the other two parts also.Īfter getting the numeric value of the 6bits of the encoded block, the program maps the numeric value to a character in the base64chars array. On the contrary, the last six 1s of the mask will leave the shifted block intact. Think about it: performing AND between anything and 0 will produce 0. Running AND on the corresponding bits of the shifted block and the number 63 (again, all zeroes, plus 111111) will do just this for us. How can we discard the first, unneeded 011100 part? The algorithm simply uses the AND bitwise operator to accomplish it. But we still have the first 6 bits in the shifted block. The program shifts the block 12 times, so the second 6 bits gets to the far-right position that we need. Now, the second part is more interesting. Running the AND operator between this and the decimal number 63 (which is …111111 in binary) is not necessary this time as all of the bits in front of the shifted block are all 0s. You'll see in our example the last 6bits of the shifted block will become 011100. Thanks for reading through the whole tutorial, I hope you managed to solve your issue! If not, you can check out this highly interesting SO answer.To calculate the first 6bit part, the program shifts the 24-bit block to the right 18 times, this way the desired 6 bits will occupy the first 6 bits of the block. Step 4 and 5: You can convert the normal Base64-encoded Python string back to the hex string from the beginning by using the string.encode() method to obtain a bytes object, passing it into the base64.b64decode() function to obtain a Base64 bytes representation, and converting it to a hexadecimal string by using the bytes.hex() method. Voilà, exactly what you wanted! But how to convert it back? Step 3: To convert the bytes object in Base64 encoding to a normal Python string, we use the code() method. This is almost what you want - but it’s not yet a normal Python string! > base64.b64encode(omhex(s)) Step 2: You use the base64.b64encode() function to take the hex string (as bytes object) and convert it to a bytes object in Base64 encoding. We require it to be a bytes object because this is the required input format of the base64 functions shown in a moment. Step 1: The initial hex string is still in a non-standardized format '02af01ff00'. You can see that the start and end values of the conversion remain the same. The output shows that you successfully converte from the hex string to the Base64 string and back to the hex string: 02af01ff00 Here’s a code example-I’ll break it down for you right after the code: import base64ī64 = base64.b64encode(omhex(s)).decode() You can convert the resulting Base64 string back to a normal string by using the one-liner expression: You can convert a hex string of the format '02af01ff00' to a Base64 encoded normal Python string by using the expression:īase64.b64encode(omhex(s)).decode() □ Recommended Tutorial: Python Base64 – String Encoding and Decoding How to Convert Base64 Encoding (Hex String) to Human-Readable String in Python? (And, no, Emojis don’t have any place in Base64, it’s VERY old school!) Index Here’s the whole table - fortunately, the encoding is small and efficient enough that I can show you the whole thing! □ Each bit position doubles the number of different encodings, so the Base64 encoding can encode 2*2*2*2*2*2 = 2^6 = 64 different characters. □ What Is Base64 Encoding?īase64 is a very minimal encoding where a minimal set of characters - A-Z, a-z, and 0-9, essentially - are encoded using only six bits. You may already know about Base64 - in that case, I’d recommend you skip the next section and jump ahead right away. Although I studied computer science a couple of years ago, I don’t have all those super basic “bits” of knowledge at the top of my head all the time. If you’re like me, you may need a quick refresher on how Base64 encoding works and what it is exactly. □ Short answer: Use the following fancy one-liner expression to convert the hex string s to a Base64-encoded Python string: base64.b64encode(omhex(s)).decode(). and will equip you with the education requirements to practise as a qualified financial adviser.

In living tissues, it is only the electrons of an atom that undergo rearrangements. Protons and neutrons are welded tightly to one another in the nucleus and change partners only under extreme conditions-during radioactive decay, for example, or in the interior of the sun or of a nuclear reactor. To understand how atoms bond together to form the molecules that make up living organisms, we have to pay special attention to their electrons. The Outermost Electrons Determine How Atoms Interact This quantity is called one mole of the substance ( Figure 2-2). If a substance has a molecular weight of X, 6 × 10 23 molecules of it will have a mass of X grams. This huge number (6 × 10 23, called Avogadro's number) is the key scale factor describing the relationship between everyday quantities and quantities measured in terms of individual atoms or molecules. One proton or neutron weighs approximately 1/(6 × 10 23) gram, so one gram of hydrogen contains 6 × 10 23 atoms. An individual carbon atom is roughly 0.2 nm in diameter, so that it would take about 5 million of them, laid out in a straight line, to span a millimeter. The mass of an atom or a molecule is often specified in daltons, one dalton being an atomic mass unit approximately equal to the mass of a hydrogen atom.Ītoms are so small that it is hard to imagine their size. Thus the major isotope of carbon has an atomic weight of 12 and is symbolized as 12C, whereas the unstable isotope just discussed has an atomic weight of 14 and is written as 14C. This is essentially equal to the number of protons plus neutrons that the atom or molecule contains, since the electrons are much lighter and contribute almost nothing to the total. The atomic weight of an atom, or the molecular weight of a molecule, is its mass relative to that of a hydrogen atom. This forms the basis for a technique known as carbon 14 dating, which is used in archaeology to determine the time of origin of organic materials. Carbon 14 undergoes radioactive decay at a slow but steady rate. For example, while most carbon on Earth exists as the stable isotope carbon 12, with six protons and six neutrons, there are also small amounts of an unstable isotope, the radioactive carbon 14, whose atoms have six protons and eight neutrons. Multiple isotopes of almost all the elements occur naturally, including some that are unstable. Thus an element can exist in several physically distinguishable but chemically identical forms, called isotopes, each isotope having a different number of neutrons but the same number of protons. They contribute to the structural stability of the nucleus-if there are too many or too few, the nucleus may disintegrate by radioactive decay-but they do not alter the chemical properties of the atom. Neutrons are uncharged subatomic particles of essentially the same mass as protons. Although the electrons are shown here as individual particles, in reality their behavior is governed by the laws of quantum mechanics, and there is no way of predicting exactly (more.) Highly schematic representations of an atom of carbon and an atom of hydrogen. It is these electrons that determine the chemical behavior of an atom, and all of the atoms of a given element have the same atomic number. Since an atom as a whole is electrically neutral, the number of negatively charged electrons surrounding the nucleus is equal to the number of positively charged protons that the nucleus contains thus the number of electrons in an atom also equals the atomic number. The electric charge carried by each proton is exactly equal and opposite to the charge carried by a single electron. An atom of carbon has six protons in its nucleus and an atomic number of 6 ( Figure 2-1). An atom of hydrogen has a nucleus composed of a single proton so hydrogen, with an atomic number of 1, is the lightest element. The number of protons in the atomic nucleus gives the atomic number. The nucleus in turn consists of two kinds of subatomic particles: protons, which are positively charged, and neutrons, which are electrically neutral. Each atom has at its center a positively charged nucleus, which is surrounded at some distance by a cloud of negatively charged electrons, held in a series of orbitals by electrostatic attraction to the nucleus.

I also wasn't sure if the sound quality would be worth the cost but it has exceeded all expectations. It definitely is!!!! Even the packaging is the cutest thing ever!!! I literally laugh out loud when I see some of the pixel art that is on there. I thought it was cute and wanted to get one, but I waited a while because I thought maybe it was just for kids (I'm 36) and I wasn't sure if it would be worth the cost. Promising review: "I had been looking on Pinterest for home office ideas and kept seeing these little mini computers in all the gamer set-ups. Get the pixel art Bluetooth speaker from Amazon for $99.90 (available in five colors). There's programmable RGB lighting under the keyboard keys (which are real buttons), and you can pick from a ton of different clock faces as well! Its speakers are powerful, its screen is bright and vibrant, and the companion app is simply packed with all sorts of customization options. The price might seem high for something that kind of sounds like a toy, but the second you pick it up, it's clear this is a high-quality piece of tech with a ton of functionality. I saw this exact Bluetooth speaker in probably dozens of Tiktoks (like this one) before I picked one up myself, and I honestly can't recommend it enough if you like a cutesy aesthetic. Beautiful, functional and the child lock feature makes it safe if kids are around. This is a must-have upgrade if you're working from home. Before the pandemic, I worked at various offices with all different kinds of stand-up desks, and this one by far is the most versatile and well made. Pep up your work space with a custom print hanging on your walls. It took a few weeks to arrive but was very well-packaged. Customize your work desk with custom poster prints from Craft & Oak. Super easy to assemble, and the built-in drawer keeps things so tidy. The child lock is *particularly* handy - I don't have kids around, but it's easy to bump into the control panel and accidentally activate the desk if you don't have this lock turned on.Īnother promising review: "LOVE this desk. I've found this feature can be a little hit or miss, so it's best to keep the area clear and just be attentive as it moves up and down. The actual standing desk feature works like a charm - with just the tap of a button, it'll raise itself up in a matter of seconds, and you can save up to four height presets so you're not having to readjust each time! An anti-collision feature is also built in, meaning the desk will stop moving if it detects an obstacle in its way. There's a thin drawer in the front - you won't be storing anything super thick in there, but it's great for putting papers, Post-its, and other small items out of the way. I have the white desk with a glass top, and it looks super modern and elegant in my living room. I've been using the FlexiSpot Comhar EG8 standing desk for well over a year now, and I really can't recommend it enough if you're ready to invest in a high-quality standing desk that combines aesthetics with function.

The team plays its home games at Hard Rock Stadium, located in the northern suburb of Miami Gardens, Florida. The Dolphins compete in the National Football League (NFL) as a member club of the league's American Football Conference (AFC) East division. As a result, some retailers are actually increasing their margins to make up for the inevitable 30% or 40% loss, sometimes pushing it as high as 4x-meaning a coat it paid $1,000 for (and may have cost closer to $500 to produce) will begin at $4,000 in the store. The Miami Dolphins are a professional American football team based in the Miami metropolitan area. You’d be a fool not to hold out for the sale. And if it’s so easy for designers to slash those prices, then surely the original number was too high to begin with, right.
