Ein schalenförmiges , stickstoffdotiertes Nanographen, das aus einem Pyrrolo[3,2-b]pyrrol-Kern besteht, der mit sechs zirkulär miteinander verbundenen Aren-Ringen substituiert ist, durchläuft die Bowl-to-Bowl-Inversion niedriger Barriere. Die Inversion ähnelt eines Regenschirms, im Wind umklappt. Der Übergangszustand ist nicht planar, sondern besitzt eine verdrehte, S-förmige Konformation Ci-Sy...

Quiz bowl answering represents a challenging task in natural language processing where few indication entities of answers are given in the questions. Traditional approaches such as manual feature engineering and bag of words representations can fail to reason the correct answers due to such lack of direct indications. Recently recursive neural network (RNN) model shows promising performance in ...

The 1930’s American Dust Bowl was an environmental catastrophe that greatly eroded sections of the Plains. Analyzing new data collected to identify low-, medium-, and high-erosion counties, the Dust Bowl is estimated to have immediately, substantially, and persistently reduced agricultural land values and revenues. During the Depression and through at least the 1950’s, there was limited realloc...

The pet food industry continues to grow steadily as a result of new innovative products. Quality control and product development tests for pet foods are typically conducted through palatability testing with dogs and cats. Palatability is the measure of intake of a food that indicates acceptance or the measure of preference of one food over another. Pet food palatability is most commonly measure...

Instead of food on your plate, consider the fare served in our pets’ bowls. A celebration of flavor happens every time a pup bounds to his bowl, or a cat responds to the sound of a can opening. Not only do we want pets to enjoy meal time, we want to ensure they’re getting proper nutrition to support a vibrant, healthy life. Just as most people probably won’t eat a bowl of wheat germ each mornin...

I use variation in childhood exposure to the Dust Bowl, an environmental shock to health and income, as a natural experiment to explain variation in adult human capital. I find that the Dust Bowl produced significant adverse impacts in later life, especially when exposure was in utero, increasing rates of poverty and disability, and decreasing rates of fertility and college completion. Agricult...

An empirical examination of the determinants of real per capita income in cities with professional sports teams from 1969-1997 shows that postseason appearances are not associated with any change in the level of real per capita income in these cities. However, in the city that is home to the winning team from the Super Bowl, real per capita personal income is found to be higher by about $140, p...

Novel bowl-like single-crystalline BaTiO(3) nanoparticles were synthesized by a simple hydrothermal method using Ba(OH)(2)·8H(2)O and TiO(2) as precursors. The as-prepared products were characterized by XRD, Raman spectroscopy, SEM and TEM. The results show that the bowl-like BaTiO(3) nanoparticles are single-crystalline and have a size about 100-200 nm in diameter. Local piezoresponse force me...

An analysis of construction was conducted in this study, and the guidelines for designing roller mills used commonly agri-food, chemical, power industries were presented. Quick machines required existence adequate mathematical models. Within framework study’s realization, a model developed we presented selected results calculations milling rollers loading from assembly’s mill bowl. The simulati...
