Soil moisture is a governing parameter in many complex environmental processes from the disciplines of meteorology, hydrology and agriculture. Since rainfall is partitioned into runoff and infiltration, the soil moisture content allows for direct information on further infiltration capability and expected runoff behavior. Spatial and temporal soil moisture variability are thus important factors...

Based on a fully coupled, high-resolution regional climate model, this study analyzed three-dimensional temperature and momentum changes in the South China Sea (SCS) from 1970 to 2000, during which period the climate shifts from a decadal La Ni~ na-like condition (before 1976/1977) to a decadal El Ni~ no-like condition afterward. With a set of partially coupled experiments, sea surface temperat...

The earliest Oligocene (3⁄433.5 Ma) is marked by a major step in the long-term transition from an ice-free to glaciated world. The transition, characterized by both cooling and ice-sheet growth, triggered a transient but extreme glacial period designated Oi-1. High-resolution isotope records suggest that Oi-1 lasted for roughly 400,000 yr (the duration of magnetochron 13N) before partially abat...

an accurate diagnosis of the morphology of the root canal system is a pre-requisite for successful root canal treatment. frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have anatomical variations or additional root canals. in this report a maxillary lateral incisor with two roots has been described.

introduction: orofacial clefts are among the most common congenital anomalies. patients presenting with orofacial clefts often require surgery or other complex procedures. a cleft lip or palate can be a single anomaly or a part of multiple congenital anomalies. the reported prevalence of cleft disease and associated anomalies varies widely across the literature, and is dependent on the diagnost...

introduction: tessier facial cleft is among the rarest facial clefts reported in literatures and there are many issues arguing about its multidisciplinary repairing techniques. tessier number 4 and 5 are extremely rare facial anomalies. there are few literatures describing these clefts and their surgical modalities. number 5 tessier cleft begins medial to oral commissure in the upper lip and ex...

BACKGROUND Waste-disposal sites are a potential hazard to health. This study is a multicentre case-control study of the risk of congenital anomalies associated with residence near hazardous-waste landfill sites in Europe. METHODS We used data from seven regional registers of congenital anomalies in five countries. We studied 1089 livebirths, stillbirths, and terminations of pregnancy with non...

BACKGROUND The prevalence of cardiovascular anomalies in Down's syndrome is well described, but there are few data on spectrum, management and outcome. The authors aimed to provide this information for infants with Down's syndrome in a defined population over a 22-year period. METHODS The regional paediatric cardiology database in Newcastle upon Tyne provided information on all cardiovascular...

and the large mass of the η meson point to large violations of OZI in the flavour-singlet J = 1 channel [2–4]. The strong (QCD) axial anomaly is central to theoretical explanations of the small value of g (0) A |pDIS (about 50% of the OZI value 0.6) and the large η mass. In this paper we review the role of the anomaly in the spin structure of the proton and highlight the interplay between the p...

Due to their unique characteristics, such as the dynamic changing topology, the absence of central management, the cooperative routing mechanisms, and the resources constraints, Mobile ad hoc networks (MANETs) are relatively vulnerable to both active and passive attacks. In MANET, routing attacks try to disrupt the functions of routing protocol by intentionally or unintentionally dropping packe...
