Movement in the Powerhouse Excavation Saguling Project, Indonesia

Ground expansion and finally sliding occurred in one corner of the 25 m deep open excavation for the powerhouse. The movement occurred in a slickensided claystone overlain by water bearing sandy gravel. The cause was expansion of the claystone followed by its weakening from water pressure in the open slickensided cracks. The excavation was finally stabilized by drainage plus reinforced sloping walls restrained by cable anchors in the rock below. The paper summarizes the pertinent soil and rock properties and describes the analyses of the movements, the corrective measures and their varied performance, an9 the professional lessons to be gained

Metabolic syndrome: definitions and controversies

Metabolic syndrome (MetS) is a complex disorder defined by a cluster of interconnected factors that increase the risk of cardiovascular atherosclerotic diseases and diabetes mellitus type 2. Currently, several different definitions of MetS exist, causing substantial confusion as to whether they identify the same individuals or represent a surrogate of risk factors. Recently, a number of other factors besides those traditionally used to define MetS that are also linked to the syndrome have been identified. In this review, we critically consider existing definitions and evolving information, and conclude that there is still a need to develop uniform criteria to define MetS, so as to enable comparisons between different studies and to better identify patients at risk. As the application of the MetS model has not been fully validated in children and adolescents as yet, and because of its alarmingly increasing prevalence in this population, we suggest that diagnosis, prevention and treatment in this age group should better focus on established risk factors rather than the diagnosis of MetS

2012 ACCF/AHA/ACP/AATS/PCNA/SCAI/STS guideline for the diagnosis and management of patients with stable ischemic heart disease

The recommendations listed in this document are, whenever possible, evidence based. An extensive evidence review was conducted as the document was compiled through December 2008. Repeated literature searches were performed by the guideline development staff and writing committee members as new issues were considered. New clinical trials published in peer-reviewed journals and articles through December 2011 were also reviewed and incorporated when relevant. Furthermore, because of the extended development time period for this guideline, peer review comments indicated that the sections focused on imaging technologies required additional updating, which occurred during 2011. Therefore, the evidence review for the imaging sections includes published literature through December 2011

Building on Sinkholes: Design and Construction of Foundations in Karst Terrain

Hundreds of sinkholes occur each year in many parts of the United States, causing significant property losses. Great potential exists for casualties unless measures are taken to minimize groundwater depletion and the increases in surface water infiltration that precipitate sinkholes. George Sowers examines the mechanisms of sinkhole formation in limestone (or karst terrain), methods for overcoming sinkhole-related failures, and techniques to avoid or minimize future sinkhole collapses. For new projects being planned, designed, and constructed, he identifies the most effective ways to prevent sinkhole problems in areas prone to sinkhole development
