10Be surface exposure dating
We use 10Be surface exposure dating to construct a high-resolution chronology of glacial fluctuations in the Sierra Nevada, California. Most previous studies focused on individual glaciated valleys, whereas our study compares chronologies developed throughout the range to identify regional patterns in the timing of glacier response to major climate changes. Sites throughout the range indicate L...
متن کاملDeciphering boulder mobility and erosion from cosmogenic nuclide exposure dating
[1] Large boulders are prominent features in many geomorphic systems and are frequently targeted for cosmogenic exposure dating. Presently, there are little data or theory predicting exposure age, erosion rate, and mobilization frequency of boulders in environments such as channels, talus slopes, or moraines. Here we explore the potential for cosmogenic isotope analysis to constrain the transpo...

متن کاملP-92: An Experiment on Osmotic Behavior of The Goat Epididymal Sperm Following Exposure to Different Cryoprotectants above Zero Temaperature
cell in biological studies. The studies showed the good response of human sperm to cryobiologic assays. However, in farm animals because of different composition of the cell membrane and presence of more unsaturated fatty acid make sperm more sensitive to oxidative stress that is one the most important factors that can affect the sperm viability during cryopreservation. The aim of the present s...
متن کاملEvaluating regression test suites based on their fault exposure capability
The test process for evolving software systems takes on a different measurement aspect than that of new systems. Existing systems are generally being modified on a continuing basis as a normal part of the software maintenance activity. This process of product modifications is fault prone because faults are introduced in the code as it is being modified. From a statistical perspective, regressio...
