  • LA Noire 'Nicholson Electroplating Arson Case' DLC Trailer [HD] - Subscribe! - Follow Us! - Like Us! Our first LA Noire DLC case, "The Nicholson Electroplating Disaster" is coming June 21st to give all the intrepid detectives out there eager to get back on the job another juicy case to crack. The story is inspired by an incident that is quite unlike the relatively obscure crimes that inspired most of the other cases in the game, and was a major national headline back in 1947 Los Angeles. Beyond just the name of the plant being changed in our fictionalized interactive version (changed from O'Connor to Nicholson, in a direct nod to -- guess who) ours also adds a ton of intrigue, twists and turns far beyond what investigators discovered in the real case -- which was much more straightforward, if shocking and embarrassing to the plant's executives. On the morning of February 20th, 1947 -- the O'Connor Electro-Plating plant at 926 East Pico Boulevard in downtown Los Angeles erupted in a terrific explosion that rocked the city for miles around. The mushroom-shaped cloud that formed over the area led many to initially panic with the thought of a nuclear bomb having been dropped on LA News reports told of planes ten miles away that were said to have felt the shudder, and of neighboring buildings' windows that shattered for blocks around. In all, 151 people were injured and 15 were killed -- the casualties ranging from innocent pedestrians (including a twelve-year old boy riding his bicycle two blocks away ...
  • Thin film & New Ideas Workshop_3_Choline Chloride EP.mp4 - WAITING FOR THE WORKSHOP - Among possible Surface Treatments, Electropolishing (EP) occupies a key role, because is the cleanest way for removing hundreds of microns of material. The standard recipe for Niobium EP foresees the utilization of a mixture of H2SO4 and HF. Literature reported results with this standard mixture are excellent, however the EP of thousands of cavities could become an industrial nightmare from the point of view of security at work. HF is not like other highly corrosive acids: if by accident it gets in contact with skin, pain is not felt, but F- ions begin to pass through, searching for the bone calcium. Up to little time ago, it was common opinion that Niobium EP without HF was impossible, unless of explosive mixtures based on perchloric acid. This is not true anymore! Since a few years a green chemistry based on ionic liquids has come to the fore, and our group was the first to EP Niobium by a harmless mixture of Choline Chloride and Urea heated around 150°C. If compared to the HF based recipe, ionic liquids provide an extremely high etching rate and a definitely low surface roughness.
  • Stable Isotopic Profiling of Intermediary Metabolic Flux in Caenorhabditis elegans Watch video protocols on JoVE - . Journal of Visualized Experiments (JoVE) is a scientific journal publishing video articles on biological experiments filmed at leading research institutions. JoVE is the first video journal indexed in PubMed. To see more of this protocol go to Stable Isotopic Profiling of Intermediary Metabolic Flux in Developing and Adult Stage Caenorhabditis elegans This video protocol was filmed at the Children's Hospital of Philadelphia. Stable isotopic profiling has long permitted sensitive investigations of the metabolic consequences of genetic mutations and/or pharmacologic therapies in cellular and mammalian models. Here, we describe detailed methods to perform stable isotopic profiling of intermediary metabolism and metabolic flux in the nematode, Caenorhabditis elegans. Methods are described for profiling whole worm free amino acids, labeled carbon dioxide, labeled organic acids, and labeled amino acids in animals exposed to stable isotopes either from early development on nematode growth media agar plates or beginning as young adults while exposed to various pharmacologic treatments in liquid culture. Free amino acids are quantified by high performance liquid chromatography (HPLC) in whole worm aliquots extracted in 4% perchloric acid. Universally labeled 13C-glucose or 1,6-13C2-glucose is utilized as the stable isotopic precursor whose labeled carbon is traced by mass spectrometry in carbon dioxide (both atmospheric ...

  • Acid Base Introduction Arrhenius, Bronsted Lowry, and Lewis Acids and Bases.
  • Titration of acetic acid (CH3COOH) with aqueous base (OH-- Titration of acetic acid (CH3COOH) with aqueous base (OH--) When a weak acid, such as acetic acid, is titrated with a strong base (OH-), the pKa value of the weak acid can be determined by plotting a titration curve. Because acetic acid is a monoprotic acid, only one equivalent of base is needed to ionize acetic acid to its conjugate base (CH3COO-). Notice that at the midpoint of the titration, there is an inflection point in the curve. At this point the concentration of weak acid equals the concentration of conjugate base and, therefore, according the Henderson-Hasselbalch equation, the pH = PKa. At the endpoint of the titration, all of the acetic acid has been ionized to its conjugate base.

  • Plastic Stone and Other Ancient Wonders Ecclesiastes 1:9 "The thing that hath been, it [is that] which shall be; and that which is done [is] that which shall be done: and [there is] no new [thing] under the sun." It is unfortunate that we so often have the sense that nothing technologically important has happened in human history until modern times. This helps maintain the illusion that humans are indeed progressing and evolving upward. Differential gears, allowing a machine to perform two functions simultaneously, were not used in modern times until 1575. However, a model planetarium using differential gears was found in a ship that sank off Greece in 78 BC While Ben Franklin is given credit for discovering electricity, electric batteries dating from 100 BC have been found in Iraq. The Gate of the Sun is a 10-ton, intricately carved stone gate in Bolivia, 13000 feet above sea level. In Mexico there are boulders with faces carved on them. They were erected between 1250 and 400 BC, carved out of boulders weighing up to 24 tons that were quarried 45 miles away from their present location. How were these giants moved and erected? Joseph Davidovits, a scientist at the Geopolymer Institute in France, believes he may know. He suggests that the builders chemically broke down the stone with acid. Then they carried the liquid stone to the present sites and poured the liquid into molds. In support of his theory, Davidovits points out that some Indians still use this method now, while traces of the acid can still be found ...
  • Lewis Structure of Perchlorate The Lewis structure of perchlorate serves to illustrate the notion of expanded octets. In this molecule, the chlorine atom must accomodate the presence of three double bonds to avoid the creation of too many formal charges on the molecule. The preliminary structure has a formal charge of 3+ while each oxygen must absorb one more electron than is necessary to neutralize the positive charge of its nucleus resulting in a formal charge of 1+ on each oxygen atom. In fact what really happens is a delocalization of the extra electrons on oxygen towards the highly electronegative chlorine atom. The stability of this anion makes perchloric acid a strong acid. Lewis structures predict that 7 bonds are shared over 4 positions for a 1 and 3/4 bond character. Recorded at Father Henry Carr High School on September 23, 2011.
