The high water storage capacity of minerals in Earth's mantle transition zone (410- to 660-kilometer depth) implies the possibility of a deep H2O reservoir, which could cause dehydration melting of vertically flowing mantle. We examined the effects of downwelling from the transition zone into the lower mantle with high-pressure laboratory experiments, numerical modeling, and seismic P-to-S conv...

[1] Water enters the Earth’s mantle by subduction of oceanic lithosphere. Most of this water immediately returns to the atmosphere through arc volcanism, but a part of it is expected as deep as the mantle transition zone (410–660 km depth). There, slabs can be deflected and linger before sinking into the lower mantle. Because it lowers the density and viscosity of the transition zone minerals (...

The protein nephrocystin-4 (NPHP4) is widespread in ciliated organisms, and defects in NPHP4 cause nephronophthisis and blindness in humans. To learn more about the function of NPHP4, we have studied it in Chlamydomonas reinhardtii. NPHP4 is stably incorporated into the distal part of the flagellar transition zone, close to the membrane and distal to CEP290, another transition zone protein. The...

zones showed unstable results with an unacceptably high complication rate.1-3 This led to design of a 9.0 mm hyperopia ablation profile.4 Today, most laser manufacturers offer relatively large treatment zones for hyperopia. A 5.5 to 6.0 mm optical zone and 9.0 mm ablation zone diameter seems to be the current standard. Figure 1 shows some examples of nominal optical zone (OZ) and ablation zone ...

PURPOSE We determine whether biochemical prostate specific antigen (PSA) failure can be accurately predicted from preoperative serum PSA combined with 6 morphological variables from radical retropubic prostatectomy specimens in men with peripheral zone cancers. The unexpected limitation imposed by preoperative serum PSA on biochemical failure led us to compare peripheral zone to transition zone...

Abstract. The towns of Pasni and Ormara were the most severely affected by 1945 Makran tsunami. water inundated land for almost 1 km at Pasni, engulfing 80 % huts town, while tsunami 2.5 km, washing away 60 huts. plate boundary between Arabian Plate Eurasian is marked subduction zone (MSZ). This in November was source a great earthquake (8.1 Mw) an associated Estimated death tolls, waves arriva...
