Insights into dike nucleation and eruption dynamics from high-resolution seismic imaging of magmatic system at the East Pacific Rise.

Models of magmatic systems suggest that the architecture of crustal magma bodies plays an important role in where volcanic eruptions occur, but detailed field observations are needed to evaluate them. We present ultrahigh-resolution reflection images of magma bodies beneath a region of multiple eruptions along the East Pacific Rise derived from three-dimensional seismic surveying. The observations reveal magma bodies with elongate ridges and troughs vertically aligned with seafloor eruptive fissures that we interpret as remnant dike root zones where repeat dikes nucleate.

The Alternatives to Traditional Materials for Subsoil Stabilization and Embankments.

Major infrastructure projects require significant amount of natural materials, often followed by the soft soil stabilization using hydraulic binders. This paper presents the results of a laboratory study of alternative waste materials (fly ash and slag) that can be used for earthworks. Results of high plasticity clay stabilization using fly ash from Serbian power plants are presented in the first part.

CONTINUOUS NON-INVASIVE ARTERIAL PRESSURE DEVICE AS AN ADJUNCT TO RECOGNIZE FLUCTUATING BLOOD PRESSURES DURING ELECTIVE CESAREAN SECTION UNDER SUBARACHNOID BLOCKADE (SAB).

Background: Measuring non-invasive blood pressure (NIBP) in less than one minute intervals (STAT NIBP measurements) is not always feasible. Therefore, large number of undetectable hypotension episodes can only be recognized with continuous beat to beat monitoring of blood pressure, for example, by continuous non-invasive arterial pressure monitor (CNAP).

Objective: The purpose of the current study was to investigate whether CNAP correlates well with conventional intermittent oscillometric NIBP during elective cesarean sections under subarachnoid blockade (SAB) and whether CNAP based patient management results in improved immediate maternal vasopressor requirements and improved immediate fetal/neonatal outcomes compared with NIBP based patient management.

Post-partum anaphylaxis: universal but successful management protocol should not deter appreciation of underlying etio-pathogenesis plethora.

Post-partum Anaphylaxis in mothers is extremely rare and has been reported secondary to initiation of the breast-feeding. However, we hereby report the occurrence of post-partum anaphylaxis in a post-partum patient in the absence of the initiated breast-feeding.

Multiple mechanisms of rhabdom shedding in the lateral eye of Limulus polyphemus.

Rhabdom shedding in horseshoe crab lateral eye photoreceptors was studied with anti-opsin and anti-arrestin immunocytochemistry. Two, possibly three, distinct shedding mechanisms were revealed in animals maintained in natural lighting. Transient rhabdom shedding, triggered by dawn, is a brief, synchronous event that removes up to 10% of the rhabdom membrane.
