What are the best materials for drawing manga?
Hi There! Woo! What a great question. It's important that you try a lot of different materials and find something that you really enjoy using. If you don't like using it, your work will really suffer. However, here is a list of what I like and why. 1. Lightly textured sketchbook paper is great because for manga and cartooning, it is a perfect balance between the required inking (it doesn't bleed!) and the minimal shading. If you like doing "beauty shots" however, you will want something with a little higher texture so your shading turns out more smoothly. 2. You're going to laugh...but I use the cheapest mechanical pencils you can find! I doodled with them for years before I got seriously into drawing so they are just my favorite to work with because I know how to manipulate it into a beautiful product. (Especially with shading.) I put them in high quality grippers though, for better control. However, if you're sick and tired of your mechanical pencil, there is nothing better than Prismacolor pencils. They come in a wide range of hardness, from soft, thick and black to thin and grey. They can break pretty easily though, so be careful in that aspect. Pencils are a very personal tool and you want to test drive all available brands to find the one you click with. 3. One of a the little known tools that works very well is the fine tipped permanent marker. (You know, Sharpie's?) They make extremely clean lines on low texture paper, but beware on high texture paper because it looks really bad unless you press hard enough to ruin the marker. Also, you can only draw with them for long periods of time outside or in a room with all the windows open because they are extremely smelly! Ever a fan of Prismacolor, I really suggest their markers. (You can find them here: http://www.michaels.com/art/online/displayProductPage?productNum=fa0640&channelid=. They are the ones on the bottom.) That pack offers all different tips, from super thin for deep shading to an almost paintbrush like tip that is great for free hand and calligraphy. (I have that set and love them to pieces, especially for manga!) That is a very long list! I really hope all that information helps you...and I didn't suggest anything I have not used myself.:-) All The Best, Lexie
This answer won't be precise, mostly because most clutch makers consider the friction material recipe a trade secret.Quick overview of the clutch assembly for the majority of modern motorcycles:For most motorcycles, the clutch assembly is a stack of plates made of flat metal (steel and aluminum most commonly) that have a large hole in the middle making them look like a flat hoopThe plates are two typesfriction plates (metal with a friction material bonded to them like a brake pad)Plain steel plates The friction plates have outer tabs (commonly 12) that engage in slots in the clutch basket that surrounds the assemblyThe steel plates have what look like gear teeth on the inner hole - this engages in the clutch hubThe clutch hub is generally driven by the crankshaft of the engineThe base of the clutch basket is a large gear that drives the transmissionThe clutch has a set of springs and a primary pressure plateWith the clutch lever out (default) the springs use the pressure plate to sqeeze the stack of plates, making the clutch hub and clutch basket turn togetherWith the clutch lever pulled in, a mechanism pushes on the pressure plate against the spring tension and unbinds the clutch hub and clutch basket, effectively letting the engine idle and the transmission 'coast'The reason for the overview is that the material bonded to the friction plates is very important, just like a brake pad is. For a very long time, the common ingredient used in the clutch friction material was Asbestos in a glue matrix, sometimes rendered as long strands (think of a fine knit sweater, soaked in glue and let dry). It wore well and lasted a long time, but as Asbestos is dangerous stuff, it's no longer used.Based on the advertisements from the big aftermarket clutch manufacturers (Barnett, Vesrah, etc.) the common primary materials today are Kevlar, Carbon Fiber, Cork and Vesrah claims 'paper' but that's probably a polite term for something they don't want to reveal in detail. These materials are be prepared in the same way: the fibers are woven into a mat, or for non-fibrous material formed. The material is soaked in a resin and then baked or let harden to create the friction material which is then bonded (glued) to the metal friction plates. Disclaimer: There are so many variations on clutches and clutch materials that this is a really basic overview. If you want to see more specifics on the clutch composition, look at Barnett or Vesrah websites.
This is a loaded question because water is very complicated. Storage would depend on a couple of things. IS this purified water or water with some mineral content. How long will the water be stored? Will it be stored in a warm climate or a colder climate? Those factors all play into how quickly water would dissolve it;s container. Very pure water will be more aggressive and try to dissolved it;s container right away whereas water that is already full of minerals is less likely to dissolve because it is already full. If it is being stored in a warmer climate heat speeds up reactions so it would dissolved more quickly. If you are storing purified water it would be important to use an inert material so I would think about maybe stainless steel. If it’s water containing minerals you can probably store in polyethylene or other plastic approved materials for food grade materials. However you do not want to store in plastic in a heated area or for long periods of time. For example if you stored water in a plastic tank in a dessert for a year, it would most likely results in plasticizers showing up in the water. Hope this helps!
What kind of warm clothes should I bring to Detroit, MI this time of year?
Get your basic jeans and sweatshirts, long underwear really isn't necessary unless you plan on spending a lot of time outdoors, which if this is the case I would bring some long t-shirts to wear under your shirts as well. I don't know what type of coat to recommend because that depends on your style, but something along the lines of a nice warm wool coat, or a fleece lined suede coat is the kind I wear (I'm a girl) and of course nothing beats a good leather. Oh, and don't forget the boots (Timberland's are nice and you can wear them at home too), hates and gloves. Welcome to Michigan! If you are going to Detroit I would try as best as I could to not let it show that you are from out of town.
Why is the ocean water salty?
Salt in the ocean comes from rocks on land. Here's how it works: The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water). The rain erodes the rock and the acid breaks down the rocks and carries it along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers to the ocean. Many of the dissolved ions are used by organisms in the ocean and are removed from the water. Others are not used up and are left for long periods of time where their concentrations increase over time. The two ions that are present most often in seawater are are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. By the way, the concentration of salt in seawater (salinity) is about 35 parts per thousand. In other words, about 35 of 1,000 (3.5%) of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater the weight of the salt, as sodium chloride, would be about 120 million tons. And, just so you don't think seawater is worthless, a cubic mile of it also can contain up to 25 tons of gold and up to 45 tons of silver! Before you go out and try alchemy on seawater, though, just think about how big a cubic mile is. By some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 m) thick, about the height of a 40-story office building.
Metallic foams are metal that has been formed into an open cell foam. The backbone can be formed from almost any metal and then they can be over coated with other metals that are too expensive or lack the needed structural properties for their use.One popular use of metal foams is to pass gaseous or liquid materials through a foam made of, or coated with, a catalyst. This allows the materials to react and is very useful when you need a continuous reaction stream that can remain passive for long periods and doesn't require direct power. One example you may have heard about is catalytic converter used in car exhausts.
Water pollution ?!!?
Try looking up E-coli contamination in water, maybe wikipedia.
In the US Navy, all our submarines (as far as I know) are nuclear. In recent years we leased an AIP (air-ndependent propulsion) submarine (the Gotland) from Sweden for a couple of years. A very, very capable submarine, by all accounts. (see Air-independent propulsion ). And though the last diesel-electric boat in the US Navy was decommissioned in 1990, there are many still in use in other navies. Finally, there are some speciallized subs: A deep-submergence vehicle (DSV) is a deep diving manned submarine that is self-propelled. The term DSV is generally one used by the United States Navy, though several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration and surveying, and DSRVs (Deep Submergence Rescue Vehicle), which can be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions (primarily installing wiretaps onundersea cables), or both. DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole. (see Wikipedia: Deep-submergence vehicle ).The SEAL Delivery Vehicle or (SDV) is a manned submersible and a type of Swimmer Delivery Vehicle or diver propulsion vehicleused to deliver United States Navy SEALs and their equipment for special operations missions and is also operated by the Royal Navy's Special Boat Service who operates 3 SDV's.The SDV is used primarily for covert or clandestine missions to denied access areas (either held by hostile forces or where military activity would draw notice and objection).The SDV should not be confused with the larger, dry submersible called the Advanced SEAL Delivery System (ASDS). The SDV is flooded, and the swimmers ride exposed to the water, breathing from the vehicle's compressed air supply or using their own SCUBA gear. (The ASDS is dry inside, with a full life support and air conditioning system.) (See Wikipedai: SEAL Delivery Vehicle )
