Home-work: you should try to understand the primitive cells of other types of crystals. 3 most important lattice types, the simple cubic (sc), the body centered cubic (bcc) and the face centered cubic (fcc) types Parameter Now in the following table we will summarize the properties of the 3 most important lattice types, the simple cubic (sc), body centered cubic (bcc) and face centered cubic (fcc) types. The following table shows the 14 types of special lattice types with their various properties. basic lattices in 2-dimensional plane: rectangular and centered rectangular lattices, showing primitive and non-primitive cell type. The figure below shows rectangular and centered rectangular lattices. basic lattices in 2-dimensional plane: Oblique, square and hexagonal. The first figure shows oblique, square and hexagonal lattice. When conditions are imposed on primitive lattice vectors - read lecture - I, II, linked here, to know how we define them, that is relations are established that restrict their size and the angle between the various dimensions, the resulting lattices are known as special lattice types, in 2-dimension there are 5 and in 3-dimension there are 14. Reflection symmetry: Its transformed through a plane about which a reflection or mirror image of all points retain their symmetry of the lattice. All other lattice points given by are transformed to so that lattice - translational symmetry, is preserved. Inversion symmetry: A lattice point is taken as origin. The 5-fold symmetry is not possible and 1-fold symmetry is trivial. A rotation is a transformation through angles of only, about an axis passing through a lattice point so that the lattice symmetry - translational that is, is preserved. There are only 230 such fundamental symmetry operations. These symmetry are referred to as “ point group symmetry” and together with obedience to translational symmetry referred as “ space group symmetries“. There are further symmetry operations that non-Bravais lattices such as “ lattices with a basis” must satisfy. reflection about a plane passing through a lattice pointor.Thus in 3-dimensional lattices the 14 classes of Bravais lattices are categorized into 7 types or systems of fundamental lattices. In 3-dimensional geometry there are a total of 14 classes of lattices. This means in 2-dimensional lattice constructs we have only 5 types of lattices which satisfy additional symmetry operations. But due to the constraint of translational symmetry the total number of symmetry operations that the lattices can satisfy is reduced to a minimum. ![]() Lattices satisfy additional symmetry operations. In our last two lectures, here, - we saw that all lattices must satisfy a translational symmetry given by the lattice displacement vectors which qualifies them to be known as Bravais lattice. Based on their properties we will classify them into various types and classes. ![]() In this lecture we will follow through our basic knowledge gained in the last lecture, - lecture - I, II, and shed light on the most interesting properties of crystal lattices, viz. ![]() A representative structure for symmetry as would be exhibited by eg a lattice.

![]() ![]() Rabach says-because cream hair removal, while painless, can be irritating, and leave skin more sensitive to the sun. “Make sure to diligently use sun protection, (as always!)” Dr. Okereke says this is important because "it bypasses pigment in the skin and gets directly to the pigment in the hair follicle." "IPL isn't specific enough and targets too many wavelengths and interferes with pigment whereas the NdYag 1064 laser is safer because it has a longer wavelength." Dr. "For darker skin types, I prefer the NdYag laser as there's less of a risk for hyperpigmentation," explains Dr. Though, darker skin tones may want to steer clear of this one. These at-home lasers (IPL is short for Intense Pulsed Light) convert light to heat and essentially kill the hair follicle-this is a permanent solution, though even laser can need maintenance a couple times a year. Similarly to waxing, the payoff will last a little longer since you're getting the hair at the root, but this method can be slightly more painful for some as well. “It’s an at-home device that removes hair by yanking many hairs out from their roots at the same time,” Dr. Okereke describes, she recommends only using a single blade razor (aka not the one you shave your legs with) as this textured hair is already more prone to ingrowns and multi-blade razors are a trigger for ingrowns.Īn epilator acts like multiple tweezers working at once. ![]() For hair that's "coily, curly, or kinky" as Dr. Rabach, at-home dermaplaning is “a good way to remove fine vellus hairs (aka peach fuzz) and also remove the thin top layer of dead skin.” Like almost every option on the list, this is a temporary solution. "Daily sunscreen use is critical to prevent hyperpigmentation as waxing the face exfoliates the top layer of skin, leaving it more prone to sun damage," says Dr. Another reminder: Don't forget to follow up with sunscreen if you're headed outside. Rabach says-she cautions “to follow the directions labeled on the package closely!” When using a kit that requires heating up, be careful not to overheat the wax to prevent burns. “At-home waxing kits are another non-permanent but effective way to remove hair,” Dr. For waxing, specifically, she says the American Academy of Dermatology recommends avoiding retinoid creams for two to five days prior to waxing to avoid extra irritation or the potential to remove skin along with the hair (ouch!). And no matter which route you choose to take, "be mindful of medications, such as certain antibiotics or birth control, which can cause the skin to be sensitive," reminds Uchenna Okereke, MD, a dermatologist based in Brooklyn, NY. Read on as we’ve rounded up all your options so you can pick the one that’s best for you. Regardless of the cause, choosing to remove some or all of your facial hair is your prerogative-and naturally, the beauty world has come up with a number of ways to go about facial hair removal. "If you are female, and have coarse dark facial hair, you should make sure that everything is okay inside your body by getting your hormones checked by a board-certified dermatologist or endocrinologist,” she says. One thing to note is that for a small percentage of women, “facial hair can be a sign of an underlying endocrine disruption, meaning your hormones are out of balance, which can be a result of conditions like PCOS,” says Dr. “For example, Caucasian British women, in this study, had statistically less facial hair than Caucasian Italian women." “Women in certain ethnic groups (not necessarily race) have more hair than others," says Morgan Rabach, MD, a dermatologist in NYC. (No, you're not alone in plucking those chin hairs.)

The 1/24 RC Caterpillar D7E Bulldozer by DCM/Racemasters is quality built for maximum fun. The sound, as heard in the video below, comes from a diesel sound generator and speaker which is set into a 3D printed speaker box. The tracks that help the D10 dozer get around are powered by gear motors and the blade is operated using linear servos. “I prefer ABS as I can weld parts together with acetone and I always utilize vapor smoothing after some post print sanding to bind all layers together and give the part a nice finish,” Hatala tells us. Prior to being post processed and painted I use a simple CAD program like Autodesk to design, and I use two Afinia H479s currently. “3D printing, which I have been involved in for 4 years, has allowed me to take model building to the next step in detail and ease. “I am a member of RC Truck and Construction and enjoy building scale construction equipment,” Hatala tells.

![]() ![]() Guide On Cutting and Polishing Rocks With A DremelĬutting rocks with a Dremel is more straightforward than many people think it is. You won’t be using sandpaper during this phase but you will be using a polishing compound made from some type of oxide or diamond. This is when you remove all of the fine scratches and you begin to see a mirror finish on the surface of the rock. The third and final phase is the polishing phase. The second phase I like to call the sanding phase because you’re still removing material but not as fast as the cutting phase (sandpaper grit should be 600 to 1200 range). The first phase will be the cutting phase and this is where you will use the most coarse sandpaper (the lower the number grit the more coarse the paper is). I like to break the process down into 3 phases. You’ll need a decent set of eyes, protective gear, a rock or gem with a Moh’s hardness of 5 or less, Dremel, bits and attachments, a polishing compound, and a diamond saw if you’re going to be cutting. Of course, there’s a bit more to the process, but we’ll get to that in a second. A polishing wheel is the second requirement.A sanding attachment that allows you to use different coarseness of sandpaper.You’ll need two attachments for polishing gems with a Dremel. ![]() Keep reading below to learn the basics of polishing rocks with a Dremel tool.Ī Dremel can do numerous tasks, and cutting and polishing stones are two of them.

He called Sirota “overzealous” at the time. Evans, who is now a Democratic member of Congress, fired Sirota. But the race got intense early, and David Sirota, then working as the deputy campaign manager for Evans, was part of an effort to cut down White’s support: creating a bogus website, purporting to be the official home page of the White campaign, and using it to promote a racially charged quotation, deliberately taken out of context.
