Abstract Acoustic logging while drilling (LWD), characterised by simultaneous and logging, is widely used to obtain the elastic parameters of formation around borehole. Most published monopole acoustic LWD simulation waveforms are routinely presented as pressure. However, these pressure disagree with voltage recorded in experiments. Here, find out reason inconsistent two waveforms, both piezoel...
Diseases consequence on individual work as much consequences of being absent from are matters interest for decision makers. We analyzed lengths absenteeism and related indirect costs patients with a paid activity in the year following diagnosis early stage breast cancer, prospective OPTISOINS01 cohort. Both human capital friction approach were considered valuation lost working days (LWD). For a...

Anchored Large Woody Debris (LWD) is increasingly being used as one of several nature-based coastal protection strategies along the north-western coasts Canada and US. As an alternative to conventional hard armoring (e.g., seawalls), its usage widely considered be less harmful ecosystem while maintaining ability protect beaches against wave attack erosion. The effects seawalls on have been exte...
The extraction of oil and gas typically involves drilling boreholes through various subsurface strata. Abrupt variations in the formation properties can severely compromise borehole stability if process is not adequately controlled. Certain events result influx/efflux fluids fissures or fractures wall. This causes a destabilization operation known as “kick” which, controlled, may lead to seriou...
The SHOX gene encodes for a transcription factor important for normal bone development. Mutations in the gene are associated with idiopathic short stature and are responsible for the growth failure and skeletal defects found in the majority of patients with Léri-Weill dyschondrosteosis (LWD) and Langer mesomelic dysplasia. SHOX is expressed in growth plate chondrocytes where it is supposed to m...
We report on a mother and son affected with an unusual skeletal dysplasia and anterior segment eye abnormalities. Their skeletal phenotype overlaps with the SHOX-related skeletal dysplasias and is intermediate between Leri-Weill dyschondrosteosis (LWD) and Langer Mesomelic dysplasia (LMD). The mother has bilateral Peters anomaly of the eye and was reported as having a new syndrome; the son had ...
This paper presents a wellbore-stability study of the San Andreas Fault Observatory at Depth (SAFOD) research borehole located near Parkfield, California, USA. In the summer of 2005, the SAFOD borehole was drilled successfully through the active trace of the San Andreas Fault (SAF) in an area characterized by fault creep and frequent microearthquakes. In this study, we report how the analysis o...
For the past 45 years GerrtU.Jny has lwd two health care systems: one in the former Federal Republic of Germany and one in the former German Democratic Republic. The system in the Federal Republic was undergoing some imponant reforms when German reunification took place in October 1990. Now the system in eastern Germany is undergoing a major transformation to bring it more into line with that i...
