![]() ![]() At pilot- or full-scale treatment, cometabolic and direct dechlorination may be indistinguishable, and both processes may contribute to contaminant removal. Cometabolic dechlorination does not appear to produce energy for the organism. ![]() In this case, contaminants are degraded by microbial enzymes that are metabolizing other organic substrates. Anaerobic dechlorination also may occur via cometabolism where the dechlorination is incidental to the metabolic activities of the organisms. In anaerobic metabolism, nitrate, sulfate, carbon dioxide, oxidized metals, or organic compounds may replace oxygen as the electron acceptor. Depending on the contaminant of concern, a subset of these activities may be cultivated. EPA 2006 Engineering Issue: In Situ and Ex Situ Biodegradation Technologies for Remediation of Contaminated SitesĪnaerobic: Direct anaerobic metabolism involves microbial reactions occurring in the absence of oxygen and encompasses many processes, including fermentation, methanogenesis, reductive dechlorination, sulfate-reducing activities, and denitrification. These conditions may be present naturally but often in the presence of a source area oxygen and a substrate such as methane or propane will need to be introduced. For aerobic cometabolism to occur there must be sufficient oxygen and a suitable substrate which allows the microbe to produce the appropriate enzyme. This can sometimes be reversed by adding oxygen in the form of air (air sparging, bioventing), ozone, or slow oxygen release compound (e.g., ORC(r)).Īerobic dechlorination may also occur via cometabolism where the dechlorination is incidental to the metabolic activities of the organisms. Degradation of contaminants that are susceptible to aerobic degradation but not anaerobic often ceases in the vicinity of the source zone because of oxygen depletion. The bacteria uses a carbon substrate as the electron donor and oxygen as the electron acceptor.

They can only exist in solutions and are practically not used. 2 acids are examined in this case as hydroxyls – chrome HCrO₄ and dechrome H₂Cr₂O₇. Chromium in the oxidation state of +6Ĭompounds of chromium in which it displays an oxidation state of +6 are strong oxidizers. Salts where chromium at an oxidation state of +3 acts as a cation display all typical properties of salts (most of them are soluble in water and hydrolyze – they decompose in water with the formation of chromium hydroxide Cr(OH)₃):Ĭhromium salts with an oxidation state of +3 can take part in oxidation-reduction reactions, for example in the following:ĢCrCl₃ + 3Zn + 4HCl = 2CrCl₂ + 3ZnCl₂ + 2H₂ (in the reaction between hydrochloric acid and zinc, atomic hydrogen is released, which reduces the chromium cation to the chromium cation). Chromium (II) oxideĬhromium (II) oxide is formed in the decomposition of chromium carbonyl (with heating):Ĭr(CO)₆ = CrO + 5CO + C. The reductive ability of Cr²⁺ salts is very high (in some cases these salts can even displace hydrogen from water). Hydrogen released in the course of reaction reduces Cr³⁺ to Cr²⁺. They are usually obtained by oxidation-reduction reactions from chromium (III). Salts of chromium (II) have a bluish color. The compounds are colored – chromium (II) oxide is black, and the hydroxide is yellow. Chromium in the oxidation state of +2Ĭhromium (II) oxide and hydroxide CrO and Cr(OH)₂ are compounds which display typical base properties. In compounds (which are brightly colored in the majority of cases), chromium displays several possible oxidation states - +2, +3, +4 (encountered quite rarely, chromium oxide CrO₂ is known), +6. ![]() ![]() ![]() As an example, Devi is A common Indian surname that means goddess.

Wu – The Wu name refers to The Wu State, which existed from the 11th century BC to 473 BC in what is now Jiangsu Province, China. His descendants adopted the name as their surname. During the spring and autumn, this gave a counselor famous for his high moral character. Then The family name is derived from a region referred to as Liu Xia within the state of Lu. Liu – This surname derives from the state of Liu, which granted to a descendant of the model emperor Yao. In gratitude, the family and all the servants and retainers took “plumtree” as their last name. So it was in memory of a time hundreds of years ago when a family was in exile in a wilderness with no food, the refugees came across a plumtree grove which saved their lives. Li – The name “Li” in Chinese means “plumtree”. So he invented the bow and arrow, and was the in charge of the production, he was given as surname in honor of his works, the character represents Zhang, which is made of the symbols for ‘bow’ and ‘long,’ meaning to ‘stretch open a bow.’ Nowadays it is used as a German surname.

His father provided nicely for the family working at Lear Sigler, and his mother also worked outside the home at Carbonau, a company that made speaker parts. John was doted on and loved tremendously by his parents in fact, John said he was just plain “spoiled” as a child. The couple was married for eight years before they welcomed the birth of their only child, a son they named John J. Ruth and John were happily married on November 3, 1944, in Grand Rapids, but because of time and money, they didn’t get a honeymoon. During his time in the service, Ruth had an opportunity to visit John on the ship around Thanksgiving, and she was the “only” girl onboard. The two began dating however after the bombing of Pearl Harbor, John followed the same patriotic calling of other young men, and enlisted in the U.S. It was here that Ruth met her future husband, John Kooiman, who was the son of the owner of the general store in town. The family later moved from Minnesota to a farm in Tallmadge Charter Township, Michigan. The girls were all close in age, but different as day and night. Ruth was the oldest of three Pilversack girls, and they undoubtedly filled the house with their share of laughter, spats and memories. It is said that everything is in a name – well after her mother found out that “Alvina” was the name of one of her father’s former girlfriends, she insisted her daughter be called Ruth. In the fall of 1922, the couple was anxiously awaiting the arrival of their first child, and on October 18th, they welcomed the birth of a daughter they named Alvina Ruth. They lived a modest life in Alexandria, Minnesota, where William earned a living as an auto mechanic. William Pilversack and his wife, Bessie (Barnhard), were far removed from these things that characterized the 1920s. The politics of the time were as turbulent as ever, yet industry had made the U.S. Harding, America entered into the 1920s with confidence. ![]() Under the leadership of President Warren G.

![]() ![]() (total of both rear corners) = total rear weight (R) (total of both front corners) = total front weight (F) The more you increase the front bias number, the more steering you will find. My truck in the picture totals out at just over eight pounds, with a front weight bias of 47.8%, and rear bias of 52.2%. This way you can measure one corner at a time, and then total up your readings.Ī good starting point for weight bias (front to rear) is 47%-front bias, and 53%-rear bias. When only using one scale, place the scale under one corner at a time, while the other three wheels are propped up by a solid object of the same height as the scale. Multiple digital scales like these can be pretty pricey. The scale set (below) is an elaborate one and not totally necessary to get the information you need. Keeping track of your truck's weight will give you a good idea of what needs to be done to get your chassis where it needs to be. This also helped keep the chassis flat off of high-speed jumps. This helped with steering and improved handling when using engines that generated a lot of torque. of lead (tire weight tabs) to the front skid plate. This photo shows where I mounted two ounces. Adding weight to specific areas can help. Sometimes you need to get just a little bit more out of your chassis. This also works for items like toe links and push rods. For example, if you want to reduce the weight at the rear of the chassis, but not at the front, you can replace just the rear pivot balls with a set of aluminum pivot balls. It's a good way to shed some weight in a specific area. You may choose to replace steel components with aluminum counterparts, like the pivot ball (#4933X) in this photo. There are many items that can be removed or swapped with lighter versions of the same item. There are different ways to achieve desired results. So much can be gained from correct balance. I measure the front to rear weight bias on all of my race vehicles. This will change the feel of the truck, and better suit your driving style or track conditions. However, when you get down to less than eight pounds, you may try moving some of the weight around to different areas of the truck. Most everyone knows that removing unnecessary items such as the starting system, and the reverse components will knock off the ounces. ![]() This weight range offers a good balance between response and stability. I've found that 7.5 to 8.0 pounds is a great range for the Revo. Sometimes, removing too much weight can cause the truck to be unstable. Removing weight is common for making a more responsive race truck. This helps balance the chassis after removing the EZ-Start® electric starting system from the engine. ![]() I place my steering servo on the left side (drivers side). This will save a little bit of weight and will leave you the choice of mounting the servo on the left or the right-hand side of the chassis. of torque, so only one servo can be used. I recommend using a servo with at least 110oz. The twin stock servo set-up is great for bashing and novice-level racing, but when facing the demands of competitive off-road racing, a high-powered/high-speed servo is what you'll need to transition from left to right-hand corners quickly. Be careful not to over-grind this area because this is where the two rear suspension pins are captured for the front suspension arms. This can slow steering response and limit range when under acceleration. When the suspension is fully extended, the inner rod ends on the steering links may rub against the bulkhead halves in the areas indicated below. Eliminate the interference between the rod ends and the bulkhead You shouldn't need to remove any more material than what is shown in the photo.Ĥ. Remove material, as needed, to get full range from the bellcrank (left to right). Right - This photo shows how the bellcrank and the hinge pin retainer meet after the mod.Īfter substantially increasing the range of the steering bellcrank, the part of the arm that connects to the servo will now interfere with the outside of the hinge pin retainer, where it mounts to the bulkhead (See photo).
