Acid dissolution is a technique of removing a fossil from the surrounding rock matrix in which it is encased by dissolving that matrix with acid. Fossilized bone, though strong enough to be preserved for thousands or millions of years, is often more delicate than rock. Once a fossil is discovered, scientists must remove the fossil from its surroundings without damaging the fossil itself. Scient...

In an experiment using two-bidder first-price sealed bid auctions with symmetric independent private values and 400 subjects, we scan also the right hand of each subject. We study how the ratio of the length of the index and ring fingers (2D:4D) of the right hand, a measure of prenatal hormone exposure, is correlated with bidding behavior and total profits. 2D:4D has been reported to predict co...

The goal of this study is to assess the rehabilitation Bahr Awlad Mohamed canal.The canal was rehabilitated by installing lining trapezoidal cross-sections. Before and after process, a field investigation, hydraulic hydrographic measurements, mathematical model (Sobek – 1D) were conducted. According findings, canal's improved average water velocity from 0.18 m/s 0.32 m/s, Manning roughness coef...

Abstract Urbanization and climate change have resulted in an increase catchment runoff, often exceeding the designed capacity of sewer systems. The decision to modernize a system should be based on appropriate criteria. In engineering practice, above is commonly achieved using hydrodynamic model simulation various rainfall events. article presents methodology analyze effect characteristics para...
