O-9: Duration of Enzymatic and Mechanical Denudation: Have any Effect on Fertilization Rate and Embryo Development?
Background: Intracytoplasmic sperm injection (ICSI) is the choice option for treatment of couples with severe male infertility. Recent studies indicate that the ICSI procedure or the technique itself cannot increase chromosomal abnormalities observed in born children. It maybe result of the Materialss used during ICSI procedure such as PVP and hyalorunidase. Activation of the oocytes might be c...
متن کاملAge Constraints and Denudation Rate of a Multistage Fault Line Scarp: an Example from Southern Italy
The morphological evolution of a carbonate fault line scarp from southern Italy, generated by transpressional faulting and evolved by slope replacement, has been reconstructed. C dating of faulted slope deposits (ages included between 18 ka and ~8 ka BP) have been performed to constrain the Late Pleistocene — Holocene evolution of that scarp. Longto short-term denudation rates have been also ev...

Rapid, long-term rates of denudation
High rates of erosion (1-15 mm/yr) of fluvial strata have persisted over intervals of 0.2-1.5 m.y. and across areas of 60-2000 km 2 in the Cenozoic foreland basin of northern Pakistan. These rates occur in areas associated with thrust shortening, and they indicate that erosion nearly kept pace with the rates of latest Miocene to Pleistocene uplift. Such high rates of erosion are predicted to pr...
متن کاملGeomorphic Controls on Andean Denudation Rates
To predict erosion rates throughout the Andes, we conducted a multiple regression analysis of the sediment discharge from 47 drainage basins in the Bolivian Andes and various topographic, climatologic, and geologic parameters. These mountainous basins are typically large (17–81,000 km; km), often have decades of measurement mean p 11,000 data on daily water and sediment discharge, and display a...
