Earthquakes in subduction zones rupture the plate boundary fault in discrete segments. One factor that may control this segmentation is topography on the downgoing plate, although it is controversial whether this is by weakening or strengthening of the fault. We use multichannel seismic and gravity data to map the top of the downgoing oceanic crust offshore central Sumatra, Indonesia. Our surve...

We wish to respond to the letter by Shryock et al. (2005) regarding our paper (Burgos et al., 2005). Their comments were, regrettably, inaccurate. First, Shryock and colleagues contended that we tested chloramphenicol, nalidixic acid, tetracycline, and penicillin because of their widespread use in dairy cattle. This is obviously incorrect, as some of these agents most certainly are not used in ...

The effects of Mg additions on the Fe-containing intermetallic compounds and heterogeneous nucleation ?-Al were investigated in Al-1.4Fe-0.7Mn- x alloys using scanning electron microscopy (SEM) transmission (TEM). experimental results show that morphology Al 6 (Fe,Mn) eutectic structure was significantly modified from needle-like to plate-like then Chinese Script with increasing concentration. ...

S uzuki et al. (1) take a close look at how kinetochores change shape when spindle microtubules tug on them. They fi nd that only part of the kinetochore stretches and identify a protein that might confer this ability. Kinetochores, which hook the fi bers of the mitotic spindle to chromosomes, are more than passive fasteners. Fashioned from more than 100 proteins, the structures are dynamic and...

In this paper we introduce the SpeakCorrect system which is a Computer Aided Pronunciation Training (CAPT) system for native Arabic students of English. The system is designed with optimized performance for the target users group. It is L1 dependent system and only the frequent pronunciation errors of native Arabic speakers are examined. Several adaptation techniques such as Speaker Adaptive Tr...

The current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. For this purpose, some experiments including hardness test, non-destructive test (NDT), metallography, and fractograpghy are conducted. The microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (SEM). The microstructural studies show that t...

It is important to measure displacement and strain distributions to prevent failures of structures. However, one point measurement method such as strain gage is widely used in industrial practice. It is time–consuming and difficult for one-point method to find the point with the maximum strain on the structures. Whole-field optical methods such as moire method, digital image correlation, speckl...

The body plan of the vertebrate embryo is established during gastrulation by the formation of mesoderm, separating the ectodermal and endodermal germ layers. Embryonic mesoderm, formed in the primitive streak, migrates anteriorly and is divided along the mediolateral axis into distinct populations including axial, paraxial, intermediary and lateral plate mesoderm. The antagonistic activities of...
