In this work, the yield stress evaluation as a function of water content for slip-prone clayey soils is studied in order to understand how yield stress decreases as water content increases, and their relation with the chemical properties. The clayey soil samples were taken from the region of Teziutlán-puebla-Mexico. Yield stress was calculated using the slump test in cylindrical geometry. Results show three zones. The first one shows an e.ponential decrement on yield stress due to lower water content in accord with clayey soils with high content of illita, followed by a second region where yield stress decreases dramatically at a certain critical water concentration, and the third one where yield stress dependence is not well-defined since the clayey soil flow is seen. Finally, it is discussed how yield stress variation due to the water increment influences the landslide risk increment.

The Pattern Electroretinogram:a Clinical Perspective

Nesting Biology and Site Selection of Olive Ridley—A Coherence of Nature

第三届全球华人眼科学术大会暨中华医学会第十一届全国眼科学术大会

作者： Graham e Holder Moorfields eye Hospital London UK

The.pattern electroretinogram (peRG) is the retinal re.ponse evoked by a structured stimulus, usually a reversing black and white checkerboard. It allows both objective evaluation of macular function and a direct assessment of retinal ganglion cell function. There are two main components to the normal peRG: a positive component (p50) at approximately 50ms, and a larger negative component (N95) at approximately 95ms. The exact origins of the.peRG have yet to be fully as-

Nesting behaviour of sea turtles remains a subject to study, due to their enigmatic pattern of seasonal breeding activities. In the.present study, characteristics of the breeding turtle, Olive Ridley (Lepidochelys olivacea) at Ramnagar along N-e coast of North Andaman Islands were investigated, for the nesting periods 2016-2017. Olive Ridley is the dominant sea turtles, with more than 300 individuals nesting every season with at least a 75% hatching success rate. It is one of the conducive, highly protective and undisturbed nesting sites for Olive Ridley on North Andaman coast. In the.present study an initiative is made, to identify nature’s cues and the biological characteristics of Olive Ridley, which leads it to nest at Ramnagar beach, with a high hatchling success rate.

In this paper, the electronic transfer integrals, the energy gap, and the bandwidth of a planar trans polyacetylene chain are calculated in Wannier representation, in which a combination of the wave function of hydrogen like atoms is used to stand for the Wannier function. When the effective nuclear charge number Z = 2.125 and the distortion amplitude of the carbon sites u =0.0038 nm, the nearest, next, and third neighbor hopping energies obtained are -3.224 78 eV, -2.388 61 eV, 0.148 14 eV, 0.006 65 eV, and 0.006 50 eV, re.pectively. The energy bandwidth and gap corre.ponding to these values are W d =11.19 eV and e g =1.70 eV, re.pectively. These results coincide with the e.perimental values.
