![]() Plus, since many of them are low-pile (though, again, this depends on the product you choose), they trap relatively little grime. Carpet tiles are easy to clean and replaceĬarpet tiles can be vacuumed just like any other carpet. That’s not a problem with carpet tiles since they’re composed of small sections to start with! 5. And once you’ve sliced into the roll of carpet, the entire area you cut that shape out of goes to waste. Every time you need to carpet around a corner, an obstacle, or anything that’s not a 90° angle, you have to cut it out of that roll of carpet. Like we said, broadloom comes in 12- to 15-foot rolls. Whether you need to carpet an entire room or just a tiny nook, you’re going to waste a lot less material using carpet tiles than you would using broadloom. Carpet tiles, on the other hand, can be stuck directly onto existing flooring. When it comes to putting in carpet tiles, it’s almost unfair to call it “installation”-because there’s no prep work involved and it only takes a few minutes.Ĭonventional broadloom carpet needs to be laid down using perimeter tack strips, a special sublayer, adhesive glue, etc. You can install carpet tiles directly over existing flooring But still-in contrast to conventional broadloom carpet, which usually comes in 12- to 15-foot rolls and needs to be installed by a professional, it couldn’t be easier. Sure, there are some types of carpet tiles that come without a backing, and for these, you will need to use an extra adhesive. You literally just line them up (we’d recommend using a T square for this, but you do you), peel the paper off the adhesive backing, and stick ‘em down. Peel-and-stick carpet tiles are probably the world’s easiest type of flooring to install. Whatever you want to do, the answer is inevitably the same: carpet tiles. Need a single area of nylon underneath the coffee table? Carpet tiles. Want to carpet your entire office with star-patterned magenta? Buy some carpet tiles. But here’s the thing: you can just create it yourself using carpet tiles bought from any flooring store in your area. Looking for a super-fuzzy, 10-foot, cut-pile hallway runner in a mix of green and, let’s say, copper? We know-it’s an obnoxiously complicated order. They come in an endless range of materials, patterns, colors, and piles-all of which you can mix and match to create your own custom carpeting, wherever you want. Seriously-when it comes to versatility, carpet tiles are second to none. ![]() We’re so glad you asked! In no particular order, because: 1. What makes peel-and-stick carpet tiles so awesome? But carpet tiles that big (and gorgeous) are the exception rather than the norm.Īnd speaking of shape: while they’re most often sold square (another common term for carpet tiles is, in fact, “carpet squares”), it’s not unusual to find carpet tiles cut into rectangles or planks. The LCT (luxury carpet tile) product from Proximity Mills we mentioned a moment ago comes in a 24″ by 40″ format. It really depends on the manufacturer and product-it’s not difficult to find larger or smaller squares if you need them. Plus, they’re machine-washable! What sizes do modular carpet tiles come in?Īlthough most tiles come in 18” or 24” squares, 16” and 12” tiles are common as well. Proximity Mills actually makes a type of carpet tile that uses friXion pads (essentially high-tech velcro) to stay in place with no sticky residue. These days, however, buyers have more options than ever. ![]() Carpet tiles are also occasionally known as “modular carpet”. You can find carpet tiles without adhesive backing, but as you may have guessed, these don’t fall into the “peel-and-stick” category.

Smaller bits have rounded shanks that spin as the bit is about to exit the material.Remained sharp and cool during the test, even after drilling several holes in the test material.Drilled holes in heavy-duty steel faster than any of the other bits in the test.Surprisingly sharp for a general-purpose bit that can also drill wood and plastic.Shank type: Smaller bits are round larger no-spin bits.The tips stayed sharp making hole after hole, and they remained cool to the touch during use (while using cutting oil). However, the large bits have no-spin shanks and do a great job of staying in place. We did dislike that the smaller bits have rounded shanks, as they can be a pain, particularly when the bit is about to drill all the way through the material. They drilled holes faster than the other bits in the test, which really surprised us. We were so shocked that these bits were this good that we kept drilling with them to see if it was a fluke. They didn’t walk when starting a hole, and they removed long shavings of metal, proving they remained sharp while drilling. While we’re not huge fans of general-purpose bits typically, especially when it comes to drilling metal, these Bosch bits were excellent. The set includes 21 bits ranging in size from 1/16 inch to ½ inch and is packaged in a plastic storage case. The Bosch bits’ tapered tips can quickly penetrate the metal, balance the bit, and produce a clean, even hole. Manufactured from high-speed steel and coated in black oxide, Bosch drill bits can withstand friction and heat so you can drill continuously without the bits heating up. Those looking for an all-around capable set of drill bits may want to check out the Bosch black oxide metal drill bit set. The following recommendations are all at the top of their class for metal drilling, and one (or more) may be an asset to your tool collection. Bits also need to be durable and able to withstand the friction and heat produced when drilling through metal. To qualify as one of the best drill bits for metal, the bit needed to perform well in the metal that it’s designed to drill. We tested these Top Picks products to ensure that they had what it takes for drilling metal. The bits that passed these tests were given awards based on their strengths. Afterward, we did our best to hand sharpen each of the larger bits with a file. We did our best to maintain similar speeds and pressure throughout each portion of every test. Then we moved to some heavier-duty 7-gauge flat stock, again testing how each bit made it through the test. We wanted to see how well they’d retain their edge, how hot they’d get, and how long it would take them to bore a hole in the metal. There’s only one good way to test drill bits for metal: We needed to put some holes in some metal! We grabbed some scraps of metal off our welding cart, chucked some bits into our drill, and started drilling.įirst, we drilled into some relatively light-duty 11-gauge steel angle iron, testing a few bits from each pack. ![]() Photo: How We Tested the Best Drill Bits for Metal ALSO CONSIDER: Irwin 63137 Cobalt Alloy Steel Drill Bits for Metal.BEST HEAVY-DUTY: Drill Hulk ¼-Inch Cobalt Steel Jobber Set.BEST STEP-DRILLING BITS: Comoware 5-Piece Titanium Coated Step Drill Bit Set.UPGRADE PICK: Irwin 3018002 29-Piece Cobalt Alloy Steel Drill Bits.BEST BANG FOR THE BUCK: DeWalt DWA1184 Black and Gold Drill Bit Set. ![]()

People with chronic (long-term) hepatitis B infection may later develop serious problems like liver cancer and liver failure. People can take several months to a year to recover from the symptoms. Joint pains, muscle aches, rash, and jaundice (yellowing of the skin or eyes) may occur in some people. Most of the time HBV infection is ASYMPTOMATIC. Hepatitis B virus can cause an acute illness with symptoms that last several weeks, including yellowing of the skin and eyes (jaundice), dark urine, extreme fatigue, nausea, vomiting and abdominal pain. Hepatitis B vaccine is 95% effective in preventing HBV infection and its chronic consequences, and is the first vaccine against a major human cancer. Worldwide, an estimated two billion people have been infected with the HBV and about 250 million have chronic (long-term) liver infections.A vaccine to prevent catching HBV has been available since 1982. It can cause chronic liver disease and puts people at high risk of death from cirrhosis of the liver and liver cancer. It is a major global health problem and the most serious type of viral hepatitis. Hepatitis B (HBV) is a potentially life-threatening liver infection caused by the hepatitis B virus. Hepatitis B is preventable with a safe and effective vaccine.The hepatitis B virus is 50 to 100 times more infectious than HIV.About 25% of adults who become chronically infected during childhood later die from liver cancer or cirrhosis (scarring of the liver) caused by the chronic infection.Despite there being a vaccine, globally HBV kills one person every minute.An estimated 800 000 people die each year due to HBV induced liver cancer or cirrhosis.Two thirds of those infected with HBV are unaware of their infection.About 2 billion people worldwide have been infected with the virus and about 370 million live with chronic infection and liver damage.The virus is transmitted through contact with the blood or other body fluids of an infected person.Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic liver disease, including cancer. ![]() Density – Atomic Mass and Atomic Number Density ![]() The Standard English unit is pounds mass per cubic foot ( lbm/ft 3). The standard SI unit is kilograms per cubic meter ( kg/m 3). In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. It is an intensive property, which is mathematically defined as mass divided by volume: Typical densities of various substances are at atmospheric pressure.ĭensity is defined as the mass per unit volume. For example, the neutron number of uranium-238 is 238-92=146. We can determine the neutron number of certain isotope. Therefore, we cannot determine the neutron number of uranium, for example. Each nuclide is denoted by chemical symbol of the element (this specifies Z) with tha atomic mass number as supescript. The various species of atoms whose nuclei contain particular numbers of protons and neutrons are called nuclides. Nuclides that have the same neutron number but a different proton number are called isotones. Neutron number is rarely written explicitly in nuclide symbol notation, but appears as a subscript to the right of the element symbol. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z. ![]() Neutron number plus atomic number equals atomic mass number: N+Z=A. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Mass numbers of typical isotopes of Hydrogen are 1 2. See also: Atomic Mass Number – Does it conserve in a nuclear reaction? According to the Einstein relationship ( E=mc 2), this binding energy is proportional to this mass difference and it is known as the mass defect. The difference is a measure of the nuclear binding energy which holds the nucleus together. Mass was no longer considered unchangeable in the closed system. Note that, it was found the rest mass of an atomic nucleus is measurably smaller than the sum of the rest masses of its constituent protons, neutrons and electrons. For 63Cu the atomic mass is less than 63 so this must be the dominant factor. A nucleus with greater binding energy has a lower total energy, and therefore a lower mass according to Einstein’s mass-energy equivalence relation E = mc 2. The nuclear binding energy varies between nuclei.This increases the mass of nuclei with more neutrons than protons relative to the atomic mass unit scale based on 12C with equal numbers of protons and neutrons. The neutron is slightly heavier than the proton.There are two reasons for the difference between mass number and isotopic mass, known as the mass defect: For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63 and an isotopic mass in its nuclear ground state is 62.91367 u. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol.įor 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. One atomic mass unit is equal to 1.66 x 10 -24 grams. The unit of measure for mass is the atomic mass unit (amu). Units of measure have been defined for mass and energy on the atomic scale to make measurements more convenient to express. The size and mass of atoms are so small that the use of normal measuring units, while possible, is often inconvenient. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. ![]() ![]() Most kitchen timers have a limitation on their highest possible set time.
