Abstract:
Dear Editor, I would like to share my concerns about the increase in the number of laboratory tests in healthcare services in recent years and the harms of unnecessary test orderings. This situation causes significant problems both in the health system and in patient care.Over the past years, a noticeable increase in the number of laboratory tests has been observed. According to a study conducted in Turkey, there was a continuous increase in the use of laboratory tests between 2015 and 2019, and this increase has serious impacts on hospital costs (1). Additionally, a study in 2023 shows that u

Effects on test scores are weakly related to effects on crime, teen births, and adult employment; and (2) Parents of lower-achievers value effects on non-test outcomes relatively more than on tests while the opposite is true for parents of high-achievers

Abstract:
A number of empirical studies have measured the effect of Information and Communication Technology (ICT) on test scores, yet there is a lack of empirical evidence on the effects of this type of intervention on drop-out and repetition rates, variables that have a direct impact on years of education. This working paper analyzes rich longitudinal censal data from Peru as well as information regarding a specific program that deployed computers in 350 schools in the year 2004. Results indicate null impacts of increasing computer access on repetition, drop-out rates and initial enrollment. The large

Abstract:
Over the past decade, several long-duration subduction earthquakes took place in different locations around the world, e.g., Chile in 2010, Japan in 2011, China in 2008, and Indonesia in 2004. Recent research has revealed that long-duration, large-magnitude earthquakes may occur along the Cascadia subduction zone of the Pacific Northwest Coast of the U.S. The duration of an earthquake often affects the response of structures. Current seismic design specifications mostly use response spectra to identify the hazard and do not consider duration effects. Thus, a comprehensive understanding of the

Full text
Abstract:
Liquid contamination in dry gas seals (DGS) can come from a variety of sources, including lube oil carryover and liquid dropout, due to the Joule-Thompson effect across the seal faces, which can cause DGS failure. The physical effect of liquids on DGS performance is a topic of limited understanding, and conflicting theories exist regarding liquid-induced failure mechanisms. While tests have been performed on DGS test rigs (primarily by seal OEMs), very little testing or analysis has been specifically aimed at studying the heat generation behind DGS behavior following liquid injection, and test

Full text
Abstract:
Fitness-for-purpose analyses are being increasingly used in the engineering assessment of the safety of gas pipelines. The potential need for this arises because of the likelihood of a defect being present in the girth weld. Many of these analyses make an allowance for the residual stress caused by the weld, whilst others do not. It has been argued that if a defect survives the field hydrostatic test that the residual stress distribution will be altered and this could subsequently affect the tolerable defect size analysis. Four full-scale tests were carried out, two at each wall thickness; one

Full text
Abstract:
The primary objective of this study was to determine the cathodic disbonding behavior of several pipeline coating materials under realistic conditions and to compare the results with laboratory tests that are commonly used to evaluate CD performance of coatings. Laboratory tests were run under more realistic conditions to simulate field conditions for three types of coatings. The move toward more realistic conditions was accomplished by:-substitution of soil extract solutions for the 3% NaCl solution,-application of a lower level of polarization during the test, either -1.0 or -1.1 VΠCCS inst
