How do you iron a coat?

User Avatar
The answer to ironing coats is: don't. Put the coat on a good-quality rust-proof and hang it in your shower -- after you've finished showering, of course. The warmth and damp will quietly get rid of the creases without the shine which ironing will give. If you are a real hurry, use a thick-ish damp (wet, then well wrung-out) cloth. Don't press, just bring the iron near to the surface. It's not pressure but steam that does it. Then, assuming it is a wool coat, use a piece of smooth wood to "block" it. This means to use the wood to press down on the fabric, pushing out creases but without sideways, friction motion. This also removes some of the moisture of the steam. give your coat to dry cleaner

Does polyester contain acetate?

User Avatar
There are many kinds of polyester, some of which might contain acetate, but the most common kind does not, because most of the carbon atoms in it are part of aromatic rings and an acetate moiety does not usually contain an aromatic ring.

What is the difference between Layer 2 switch and Layer 3 switch?

User Avatar
Basically a layer 2 switch operates utilizing Mac addresses in it's caching table to quickly pass information from port to port. A layer 3 switch utilizes IP addresses to do the same. While the previous explanation is the "What", for folks in networking the following "How" is far more interesting. Essentially, A layer 2 switch is essentially a multiport transparent bridge. A layer 2 switch will learn about MAC addresses connected to each port and passes frames marked for those ports. It also knows that if a frame is sent out a port but is looking for the MAC address of the port it is connected to and drop that frame. Whereas a single CPU Bridge runs in serial, todays hardware based switches run in parallel, translating to extremly fast switching. Layer 3 switching is a hybrid, as one can imagine, of a router and a switch. There are different types of layer 3 switching, route caching andtopology-based. In route caching the switch required both a Route Processor (RP) and a Switch Engine (SE). The RP must listen to the first packet to determine the destination. At that point the Switch Engine makes a shortcut entry in the caching table for the rest of the packets to follow. Due to advancement in processing power and drastic reductions in the cost of memory, today's higher end layer 3 switches implement a topology-based switching which builds a lookup table and and poputlates it with the entire network's topology. The database is held in hardware and is referenced there to maintain high throughput. It utilizes the longest address match as the layer 3 destination. Now when and why would one use a l2 vs l3 vs a router? Simply put, a router will generally sit at the gateway between a private and a public network. A router can perform NAT whereas an l3 switch cannot (imagine a switch that had the topology entries for the ENTIRE Internet!!). In a small very flat network (meaning only one private network range for the whole site) a L2 switch to connect all the servers and clients to the internet is probably going to suffice. Larger networks, or those with the need to contain broadcast traffic or those utilizing VOIP, a multi network approach utilizing VLANs is appropriate, and when one is utilizing VLANs, L3 switches are a natural fit. While a router on a stick scenario can work, it can quickly overtax a router if there is any significant intervlan traffic since the router must make complicated routing decisions for every packet that it recieves.

Asked in Homeschooling, The Difference Between, Polyester

What is the difference between homeschooling and unschooling?

User Avatar
Alan Moses provided this answer on the Home Education Mailing List: As I understand the way the Growing Without Schooling crowd uses the terms, unschooling refers more to the process of removing your child from school and overcoming the negative effects of the compulsory education process; homeschooling is the more general term referring to home-based learning. I'd love to come up with a better term than homeschooling, due to the implication that the child is spending all their time at home (see my comments on "socialization"); but it's the best I've seen so far. Heather Millen added: The process explained [above] could actually be considered "de-schooling" rather than unschooling. Unschooling is child-led learning in a home environment rather than duplicating school and its curriculums at home. Most unschoolers don't follow lesson plans, or even have "school learning" time structured into their day. Subjects are covered when the child's interest dictates not when the "educational experts" say its time for every child to know that subject. David Mankins added: Unschooling, for this unschooler, is based in the beliefs that children: are incredible learning machines, as shown by their ability to learn language and to function in society with little or no explicit instruction are insatiably curious about the adult world, and are driven to learn by these features, and sometimes children learn *despite* our attempts to teach them! Unschoolers also believe, or at least this unschooler believes, that *imposing* an agenda on a child is more counter-productive than helpful, because it doesn't take the child seriously. I think a lot of this can be justified by reflecting on one's own learning experiences. Nobody makes me learn new things, I just do because learning is fun, or because I want to know about this subject for my own purposes (even if those purposes are as prosaic as justifying my paycheck). The same is true for children. I think it is also motivated by a certain kind of respect for the rights of children. *I* don't want to be told what or when to study, what right have I to tell another what to do and when? Unschooling requires a lot of faith in your child, that they will learn the things that are important for them to know despite not being "forced" to, that their seemingly patternless play is experimentation that will pay off in insight, and that they will stick to a subject through the "hard parts". Again, reflecting on one's own experience can help solidify this faith, as can reflecting on the behavior of one's own children. [The answer above is based on a homeschooling FAQ originally edited in 1994 by Dave Mankins for the Home Education Mailing List.] To me, "unschooling" simply means when a parent says they are homeschooling, but does not take the time, nor make the effort to do it correctly, and hinders their child's education. That is not true! I was homeschooled my whole life, and never fell behind. Infact, I knew alot more then all the kids in public school. I was unschooled, which doesn't mean I never did a work sheet, it just means that I didn't just do work sheets. Unschooling is alot more hands-on, instead of learning how yeast raises in a book, you would do an experement with yeast, and watch it raise. People always act like homeschooled kids are these weird animals that know one knows anything about, but their just like everyone else. People like you think that a child belongs in school, where they are all tought to be perfect at every subject. Which is why almost every child hates school. People are forcing them to be like everybody else. Every child learns differently, one kid may be great at math but horrible at history, another kid may be perfect at spelling, but hate science. It just depends on the kid. All the kids in school are all in a class with a bunch of other kids their age, with all different questions and all different problems, and only one teacher to answer them all. The child then doesn't get enough one on one time with the teacher, then making the subject harder to learn. I remember when I was little having total conversations with adults, who were about three times as old as me. I liked talking to adults more the I liked talking to kids, and I was one. The adults had more interesting things to talk about then the kids did, plus the kids never understood what I was talking about anyway. Lots of times when a parent unschools their child it is for a reason, not because they don't feel like doing anything. If they wanted to do that, they would just put them in school. Where the teacher raises your child for you.

What is the difference between polysporin and neosporin?

User Avatar
Neosporin is an antibiotic with three components...neomycin sulfate, polymixin B sulfate and bacitracin. If this combination is in ointment form, many times you will find it called "triple antibiotic ointment" or it's Trade name, Neomycin. Polysporin is a combination of two antibiotics, bacitracin zinc and polymixin B sulfate. By combining the three antibiotics, one may treat or prevent a wider range of bacterial infections. For more information see the Related Link. If you are allergic to penicillan, you should use Polysporin, instead of Neosporin to avoid potential hives.

What is stretch twill fabric?

User Avatar
Twill is fabric that has a diagonal pattern. It is actually woven in such a way as to create diagonal "ribs" in the fabric itself (not just colored diagonal lines). Think of cordoroy - that is a fabric with a vertical (up and down) pattern woven into it. Twill is diagonal weaving. If a twill fabric has extra "give" so that it can expand (stretch), it is a stretch twill. Stretch twill often refers to the fabric having a small percentage of lycra/spandex in it, usually 2-4%.

Why do soccer shirts have polyester?

User Avatar
Polyester is the choice of fiber and fabric for many industries. It can be applied to a wide variety of useful purposes. Being the most heavily recycled polymer worldwide, it is also used by climbers. Climbing suits, parkas, sleeping bags and other outdoor gear are using the new insulating polyester fiberfill products. One can also do winter windsurfing wearing dry suits lined with polyester fleece. Creating insulation: By creating hollow fibers it is also possible to build insulation into the polyester fiber. Air is trapped inside the fiber, which is then warmed by the heat of the body. This keeps the body warm in cold weather. Another method to build insulation is to use crimped polyester in a fiberfill. The crimp helps keep the warm air in. Polyester is an ideal fabric for this kind of insulation because it retains its shape. Cotton and wool tend to flatten over a period of time and loose the warming effect. Wrinkle resistant: Polyester is also wrinkle resistant and is used very often in everyday clothing like pants, shirts, tops, skirts and suits. Used either by itself or as a blend, it is also stain resistant and hence very popular.
