![]() ![]() This unique property of water is due to hydrogen bonding. Under standard conditions, water is primarily a liquid, unlike other analogous hydrides of the oxygen family, which are generally gaseous. Large ice crystals, as in glaciers, also appear blue. This can easily be observed in a water-filled bath or wash-basin whose lining is white. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color. Water is a tasteless, odorless liquid at ambient temperature and pressure. Water is the chemical substance with chemical formula HĢO one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Is a constant, so their respective concentrations are inversely proportional to each other. The product of the activities, or approximately, the concentrations of H + Related to its amphoteric character, it undergoes self-ionization. Water is amphoteric, meaning that it can exhibit properties of an acid or a base, depending on the pH of the solution that it is in it readily produces both H + Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 ☌ for its molar mass, and a high heat capacity. This polarity allows it to dissociate ions in salts and bond to other polar substances such as alcohols and acids, thus dissolving them. Water molecules form hydrogen bonds with each other and are strongly polar. It is also the third most abundant molecule in the universe (behind molecular hydrogen and carbon monoxide). It is the most abundant substance on the surface of Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life".

You are looking for a platform with the less coding effort to give you the best results. But the biggest challenge is to choose the right frontend app platform: PWA or native? Flutter or one native app per platform? What about React Native? If you start an app project today, there are some simple decisions, such as the cloud provider or the backend stack you will use. ![]() ![]() ![]() But three years later, Gargiulo pushed his luck too far. Tarantino implicated himself in both the security guard's murder and the disposal of Dorval's body. One of Tarantino's longtime confidants, Vincent Gargiulo, learned of the DNA evidence, and he secretly tape-recorded a September 2000 conversation with Tarantino in an "apparent effort to secure evidence that would prevent Tarantino or others from falsely implicating Gargiulo" in the killing of the security guard or Dorval, according to the FBI. In 2000, law enforcement began collecting "DNA evidence from several individuals," which turned up a match between Tarantino and a hair fragment recovered six years earlier from the getaway car in the Syosset heist, which had been abandoned near the scene, FBI officials said. Coast Guard vessel pulled Dorval's body out of the Atlantic several days later, but the investigations into both killings remained open." "With the help of others, stuffed Dorval's body in a plastic tool trunk that he then dumped at sea," the statement reads. Tarantino, learning of the pending arrest, "lured Dorval to his own death," according to the feds. Six weeks later, however, the FBI began closing in on Dorval for an unrelated racketeering indictment. As Tarantino and two of the bandits handcuffed one guard, another of the robbers, Louis Dorval, shot and killed the second guard in the back of the head as he lay face-down on the pavement, the bureau added. The first murder took place June 23, 1994, the FBI says, when Tarantino and three others ambushed an armored car and its two guards as it delivered cash to a business in Syosset. MIDTOWN - A muscle-bound gym mogul-turned-bank-robber won a free gym membership at federal penitentiaries for the rest of his life for his role in the murder of a security guard and two accomplices, the FBI announced.Ĭhristian Tarantino, 46, former owner of Synergy Fitness clubs in New York City and Long Island, was sentenced to three terms of life imprisonment without the possibility of parole Wednesday for his role in the three killings, which occurred between 19.įederal prosecutors called him a "one-man crime spree."

During the course of his academic career, Dr. His research has been focused on topics related to transportation safety, human factors, driving & bicycling simulators, autonomous vehicle simulation, and data analysis. Prior to his appointment at OSU, Hisham worked as a Research Associate in the Department of Civil and Environmental Engineering at Michigan State University (MSU). Hisham Jashami is an Assistant Professor (Sr Res) of Transportation Engineering in the School of Civil and Construction Engineering at Oregon State University (OSU) and a certified Road Safety Professional Engineer. The results provide important insights into the nature of the relationship between speed and safety and will help to guide subsequent speed limit policy decisions.ĭr. Several site-specific characteristics were also found to be strong predictors of crash frequency. Interestingly, mean speeds were found to be negatively associated with crash frequency, while the standard deviation of speed was found to exhibit a positive relationship. The results show that the locations where the speed limits were increased experienced a 5% increase in crashes, while a marginal reduction in crashes was observed where speed limits did not increase. The impacts of the speed limit increase on safety were evaluated by estimating random effects negative binomial models as part of a case-control before-after study design. These data are merged with pertinent roadway data, as well as police-reported crash data at various levels of injury severity. Speed data were obtained for the Michigan rural freeway network through probe vehicles. The maximum speed limits for trucks were also increased from 60 to 65 mph on all freeways state-wide at this same time. ![]() The speed limit increases in Michigan occurred between May 1 and June 12 of 2017, when the maximum speed limits were increased from 70 to 75 mph on approximately 600 miles of freeways. To this end, the present study evaluates the effects of increasing speed limits on the safety of rural limited access freeways while accounting for contemporaneous changes in the speed profiles of these same roadways. However, research has been more limited as to the direct relationship between speed and safety. These increases have also generally coincided with increases in both the frequency and severity of crashes. Research has consistently shown speeds to increase following speed limit increases. Maximum speed limits continue to be an important policy issue.

Your “standard” red wine glass is the top choice for spicier, medium-bodied wines like Zinfandels and Malbecs. The even-broader Burgundy glass is your best bet for delicate flavors, like those from Pinot Noir, as the wide bowl helps concentrate those pleasantly-smelling compounds at the nose. This oxidation is why decanting red wine is important, or allowing it to “breathe.” The wide bowl also allows you to swirl your wine effectively.Tall, broad-bowled glasses like Bordeaux glasses are designed for the boldest and fullest wines – think Cabernet Sauvignon or Syrah – and help some of that ethanol to escape so aromas can surface. Red wine glasses need a wide bowl to help with the inhalation of volatile compounds and to allow oxidation to occur, bringing forth even more complexity over time. Wine Enthusiast offers a multitude of glasses sure to meet any wine drinker’s needs, no matter which bottle is being uncorked. For example, if you are planning an outdoor dinner party, stemless tumblers may be more ideal that a long-stemmed glass that is more likely to get knocked over. You may also take your environment into consideration. From there, small nuances in width, shape, and length help highlight or encourage attributes like oxidation or carbonation. In general, red wine glasses have larger bowls to help enhance the aromas that collect at the surface of the wine, and white wine glasses have more narrow bowls to help maintain temperature. ![]() First, you should know that a wine glass consists of a bowl, a stem, and the foot. Bordeaux? Burgundy? Stemmed or stemless? Before you choose the perfect glass for that special bottle, it is helpful to know some basic guidelines. The world of wine glasses can be dizzying. Do some research first on your beverage of choice, its dominant characteristics, and then read below for tips on which glassware will bring out those primary notes in the most optimal ways. Choosing the right glassware is as much of an art as it is a science, and can be a ton of fun if you know what you are looking for.
