DIGGING DEEPER: FOUR LEVELS OF MEANING Recounting the plot of a movie, telling what happens, is the simplest way to explain it to someone else. But this is neither a film review nor a film analysis. It’s merely a synopsis that anyone else who sees or has seen the movie will likely agree with. This level of content may be called the referential content, since it refers directly to things that ha...

While it is assumed that reintroduction of saturated fat might be deleterious, recent research suggests that the role of saturated fatty acids needs to be re-examined. “Current dietary intake recommendations of macronutrients have targeted total fat, cholesterol and saturated fat as the principle means to improve human health,” says Bruce German, professor, Department of Food Science & Technolo...

Usually the planters used in agricultural machinery face two problems: The have to spread soil twice using tray seed planter, and it is difficult for them dig holes before planting. This study has designed a spiral digging end-effector parallel effectively quickly so that seeds can be planted easily. A was with five bits, synchronous belt, cylinder, gear motor, connecting plate based on size pu...

Leaf-cutting ant queens excavate a founding nest consisting of a vertical tunnel and a final horizontal chamber. Nest foundation is very time consuming, and colony success depends on the excavated depth. Although shallow nests may be energetically cheaper to dig, queens may be more exposed to the changing environment. Deeper chambers, in contrast, may be climatically more stable, but are more e...

Abstract The energy-saving of hydraulic excavators is evaluated by two significant indicators: operating efficiency (digging weight per unit time) and fuel consumption (volume consumed time). These indicators are only the final test results cannot quantitatively evaluate whole operation process excavator. In this paper, a complete set experimental protocols designed to quantify excavator collec...

In the aftermath of the 9/11 disaster, Mayor Bloomberg of New York City unveiled an aggressive budget plan that included the temporary suspension of glass and plastics recycling. This was considered by many to be anti-environmental, but the results of this study show that for lack of markets, even at zero or negative prices, nearly 90% of the plastic and glass set aside by thoughtful New Yorker...

The article presents an in-depth analysis of the theories soil digging. It has been shown that developed theory digging is closely intertwined with experimental data. This makes it possible to calculate all forces acting on working body by a divisible sheet, including those take into account arising vertically from moving which are determined refraction and angle sheet cut. In order characteriz...
