![]() ![]() Hyper itself is trying to establish two lines of business. A mix of media, venture and product figures is probably the right way to go if you want to back yourself into a media empire funded by venture capital returns. It’s a pretty eclectic group, but if you squint you can see the shape of the ambitions that Hyper has reflected in the parties involved. The Hyper concept sounds fresh in combination, if not in components.Ī short list of some of the people involved as advisors, mentors or investors themselves includes Alexis Ohanian, Founder of Seven Seven Six, Serena Williams, Alfred Lin of Sequoia, Garry Tan of Initialized, Harry Stebbings, Jeffrey Katzenberg, Naval Ravikant, Owen van Natta, Ryan Hoover, Ryan Tedder of OneRepublic and Sriram Krishnan of a16z. I had a chat with Buckley, Curtis and Cantor about the new fund and company and the way that they hoped to differentiate Hyper in a world of aggressively service-oriented venture firms. Product Hunt, however, is the first of what the team says will be many companies it will own, create and operate in order to provide ‘direct value’ to its portfolio companies. The fund will exist as a ‘sister company’ to Product Hunt. The fund is taking applicants worldwide though notes that some countries present legal complexities for investment. The team will be writing $300k checks for 5% of very early companies in any arena that seems promising to the partnership in a fixed deal structure that mirrors Y-Combinator. The fund is launching as a straight up venture effort, with a bit of gas added by the Product Hunt association. ![]()

![]() ![]() Tiny particles of the pigment can flake off and become airborne, and then are absorbed by the lungs. Two main theories on the cause of wallpaper poisoning events have been proposed: dust particles caused by pigment and paper flaking, and toxic gas production. Illness associated with arsenic containing wallpaper By 1890's the last brand of wallpaper using it ceased production. An article “Pretty Poison-Wreaths” described her repeated illness from arsenic poisoning leading to her death, and detailed autopsy findings of eyes and fingernails turned green from the pigment. Publicity associated the 1861 death of 19 year old Matilda Scheueur as a result of her job dusting artificial foliage with the pigment increased public awareness of the toxicity of Scheele's green. Īlthough some European nations started banning arsenic containing pigments in the 1830's and 1840's, Scheele's green did not completely fall out of favor until the 1860's. There is one example of an acute poisoning of children attending a Christmas party where dyed candles were burned. Nineteenth-century journals contained reports of children wasting away in bright green rooms, of ladies in green dresses swooning and newspaper printers being overcome by arsenic vapors. In the 19th century, the toxicity of arsenic compounds was not readily known. ĭespite evidence of its high toxicity, Scheele's Green was also used as a food dye for sweets such as green blancmange, a favorite of traders in 19th-century Greenock this led to a long-standing Scottish prejudice against green sweets. Scheele's Green was used as an insecticide in the 1930s, together with Paris Green. It had the same tendency to blacken, but was more durable.īy the end of the 19th century, both greens were made obsolete by cobalt green, also known as zinc green, which is far less toxic. Emerald green, also known as Paris Green, was developed later in an attempt to improve Scheele's Green. However, because of its copper content it tends to fade and blacken when exposed to sulfides, whether in the form of atmospheric hydrogen sulfide or in pigment mixtures based on or containing sulfur. Scheele's Green is more brilliant and durable than the then-used copper carbonate pigments. ![]() It was also used to dye cotton and linen. for wallpapers and paper hangings, and in paints, wax candles, and even on some children's toys. Scheele's Green was used as a color for paper, e.g. Woman Embroidering by Georg Friedrich Kersting(1812) It has been found that Scheele's green was composed of a variety of different compounds, including copper metaarsenite ( CuO♺sĢO)), neutral copper orthoarsenite ( 3CuO♺s The intensity of the color depends on the copper : arsenic ratio, which in turn was affected by the ratio of the starting materials, as well as the temperature. To enhance the color, the salt was subsequently heated to 60–70 ☌ (140–158 ☏). After filtration the product was dried at about 43 ☌ (109 ☏). Added to a copper sulfate solution, it produced a green precipitate of effectively insoluble copper arsenite. This produced a sodium arsenite solution. The pigment was originally prepared by making a solution of sodium carbonate at a temperature of around 90 ☌ (194 ☏), then slowly adding arsenious oxide, while constantly stirring until everything had dissolved. 4 Illness associated with arsenic containing wallpaper.The latter is the more typically reported color coordinate for Scheele's green. At least two modern reproductions of Scheele's green hue with modern non-toxic pigments have been made, with similar but non-identical color coordinates: one with hex#3c7a18 (RGB 60, 122, 24) and another with hex#478800 (RGB 71, 136, 0). By the dawn of the 20th century, Scheele's green had completely fallen out of use as a pigment but was still in use as an insecticide into the 1930s. The acutely toxic nature of Scheele's green as well as other arsenic-containing green pigments such as Paris Green may have contributed to the sharp decline in the popularity of the color green in late Victorian society. It began to fall out of favor after the 1860s because of its toxicity and the instability of its color in the presence of sulfides and various chemical pollutants. ![]() It is a yellowish-green pigment commonly used during the early to mid-19th century in paints as well as being directly incorporated into a variety of products as a colorant. By the end of the 19th century, it had virtually replaced the older green pigments based on copper carbonate. Scheele's Green was invented in 1775 by Carl Wilhelm Scheele. Scheele's Green, also called Schloss Green, is chemically a cupric hydrogen arsenite (also called copper arsenite or acidic copper arsenite), CuHAsOģ.

Rotational Reynolds number = ( Ω r p 2)/ v S E By improving the discharge coefficient the pre-swirl system reduced aerodynamic losses, and the mass flow rate was increased at certain pressure ratios or satisfied the pressure margin for blade cooling. The optimized model showed a discharge coefficient of 0.846, which was 31.7 % higher than the baseline condition. The total temperature in pre-swirl system could be characterized as the reduction in temperature by nozzle acceleration and elevation by aerodynamic losses due to friction and viscous effects in the system. Total temperature drop effectiveness was increased from 0.07 to 0.29. Results showed that the optimized nozzle reduced total pressure losses and increased mass flow rate. The single-objective optimization was performed to maximize the discharge coefficient. The optimization process included the optimal Latin hypercube design sampling method with the Kriging surrogate model and genetic algorithm. Four design variables were considered in the optimization process: Nozzle inlet length ( L), outlet length ( l), inlet diameter ( D), and radial location ( r p). CFD methodologies were validated by comparing the CFD results with experiments. ![]() Hole-type pre-swirl nozzle was optimized using CFD analysis and experiments. ![]() |
