158-μJ pulses from a single-transverse-mode, large-mode-area erbium-doped fiber amplifier

We report the amplification of 10-100-pJ semiconductor diode pulses to an energy of 158 μJ and peak powers >100 kW in a multistage fiber amplifier chain based on a single-mode, large-mode-area erbium-doped amplifier design. To our knowledge these results represent the highest single-mode pulse energy extracted from any doped-fiber system. © 1997 Optical Society of America.

La plataforma submarina y la costa atlántica Argentina durante los últimos 22.000 años

La glaciaciones ocurridas en la región expusieron en diferente grado la actual plataforma continental Argentina (océano Atlántico sudoccidental). Este trabajo de divulgación científica da a conocer un modelo de evolución paleogeográfica de las costas de la Pampa y la Patagonia, y brinda la posibilidad de localizar temporalmente la formación de los principales rasgos costeros del extremo sur de América del sur. Se incluyen además otras lecturas sugeridas relacionadas al tema.

Fibre optics monitoring of clay cuttings and embankments along London's ring motorway

Although a wide range of techniques exist for slope monitoring, the task of monitoring slopes is sometimes complicated by the extensive nature and unpredictability of slope movements. The Brillouin optical time-domain reflectometer (BOTDR) is a distributed optical fiber strain measurement technology utilising Brillouin scattering. This method measures continuous strain along a standard optical fibre over a distance up to 10 km and hence has potential to detect deformations and diagnose problems along large sections of slopes and embankments. This paper reports the demonstration of BOTDR method for monitoring surface ground movements of clay cuttings and embankments along London's ring M25 motorway. A field trial investigating varying methods of onsite fibre optic installations was conducted. The surrounding ground was artificially moved by excavating a 3 m deep trench perpendicular to the instrumented sections. Results obtained from onsite installations after slope movement demonstrate a half-pipe covered fibre optic installed on wide (200mm) Tensar ™SS20 geogrid gives the most consistent recorded strain change profile. Initial conclusions suggest this method best represents induced ground motion at the surface and hence is recommended for implementation in future sitework. Copyright ASCE 2008.

　目的　探讨大蹼铃蟾抗菌肽22 (Maximin22) 对膀胱癌 细胞株HLA2DR 及HLA2ABC 表达的影响, 并与TNF2α、 IFN2α进行比较。方法　采用肿瘤细胞培养方法,流式细胞 仪检测各实验样品对膀胱癌细胞株T24 、BIU287 、SCaBER 的HLA2DR 及HLA2ABC 表达的影响。结果　Maximin22 对 不同的膀胱癌细胞株在小剂量下即有抑制作用,并呈剂量相 关性,各实验样品未见对各膀胱癌细胞株的HLA2DR 表达 有影响,Maximin22 、TNF2α对HLA2ABC 的表达均无影响; IFN2α则对HLA2ABC 的表达有上调作用。结论　Maximin2 2 、TNF2α抗癌机制与提高肿瘤细胞HLA2DR、ABC 的表达无 关, IFN2α可通过提高肿瘤细胞HLA2ABC 的表达提高T 细 胞对膀胱肿瘤的识别杀伤能力。

Isolation and preliminary characterization of a 22-kDa protein with trypsin inhibitory activity from toad Bufo andrewsi skin

A novel trypsin inhibitor termed BATI was purified to homogeneity from the skin extracts of toad Bufo andrewsi by successive ion-exchange, gel-filtration and reverse-phase chromatography. BATI is basic single chain glycoprotein, with apparent molecular weight of 22 kDa in SDS-PAGE. BATI is a thermal stable competitive inhibitor and effectively inhibits trypsin's catalytic activity on peptide substrate with the inhibitor constant (K-i) value of 14 nM and shows no inhibitory effect on chymotrypsin, thrombin and elastase. The N-terminal sequence of BATI is EKDSITD, which shows no similarity with other known trypsin inhibitors. (c) 2005 Elsevier Ltd. All rights reserved.
