We apply spectral stability theory to investigate nonlinear gravity waves in the atmosphere. These waves are determined by modulation equations that result from Wentzel-Kramers-Brillouin theory. First, we establish that plane waves, which represent exact solutions to the inviscid Boussinesq equations, are spectrally stable with respect to their nonlinear modulation equations under the same conditi
One of the factors that can contribute to the resolution of long, doped inorganic scintillators used for nuclear spectroscopy is the variation of the dopant concentration over the length the detector crystal. In this work an investigation of such potential variations in one of the CsI(Tl) scintillators used in the calorimeter, CALIFA, of the R3B experiment at FAIR, has been performed using particl
Topology optimization is a mathematical tool for finding optimal distributions of material phases within a design domain. It is commonly used in early design stages to generate conceptual structural layouts. Ultimately, designs generated by topology optimization consist of distinct material phases with enhanced performance. Most research on topology optimization methods focuses on linear elastic m
The response of floating pile foundations in deep deposits of soft clay is governed by the settlements within the clay deposit surrounding the piles. A long-duration thermal response test (TRT) has been performed to assess the impact of heating and cooling on the geotechnical performance of a vertically loaded slender tubular steel pile in a deep deposit of sensitive clay. The results from the ins
Energy use in buildings has a significant influence on the global energy demand and environmental impacts. Among all building systems, heating, ventilation, and air conditioning (HVAC) systems are the most energy-intensive in terms of their total energy requirements. The production and operation of HVAC systems have a significant impact on the environment. These systems are also among the largest
Within the context of a sharing economy, the BE-USE project aims to develop behavioural economics experiments that test, examine and generate policy recommendations to advance sustainable urban initiatives. It aims to increase the understanding of cognitive, motivational and contextual factors affecting decision-making processes and choices in urban sharing initiatives.This report is developed und
INTRODUCTION: Despite much literature on reference values of acid-base status in umbilical cord blood at birth, there are as yet no studies performed to determine gestational age-dependent references in cord venous blood and no studies on preterm acid-base standards. Similarly, the normal reference range of Apgar scores for term and preterm infants has not yet been determined.MATERIAL AND METHODS:
Abstract Introduction: Obstetricians routinely use biochemical parameters from non-pregnant women to assess the condition of the laboring mother. However, it is well known that pregnancy leads to significant physiological changes in most organ systems. The aim of this study was to determine normal values for maternal arterial blood gases during vaginal deliveries as compared to control values fro
Ever higher levels of integration within the Integrated Circuit (IC) tomeet progressively widening scope of its application in respect of functionality,size, performance and manufacturing issues inspired developmentof the three-dimensional (3D) Stacked IC as a device havingviable architecture. However, with increased complexity, manufacturingcost increased. The manufacturing cost includes the test
Purpose: This study aims to demonstrate the suitability of text-mining toolset for the discovery of trends in quality management (QM) literature in 2000-2019. The hypothesis was formulated that as the field of study is mature, the most important trends are related to deepening and broadening of the knowledge. Design/methodology/approach: A novel approach to trend discovery was proposed. The comput
Background: Ulnar nerve entrapment at the elbow (UNE) is overrepresented in patients with diabetes, but the outcome of surgery is unknown. We aimed to evaluate patient-reported outcome in patients with and without diabetes, and to assess potential sex differences and compare surgical treatment methods. Methods: Data on patients operated for UNE (2010-2016, n = 1354) from the Swedish National Regis
The need for increased productivity in difficult-to-machine titanium alloys has pushed manufacturers to examine the potential of ultrahard cutting tool materials such as polycrystalline diamond and polycrystalline cubic boron nitride as alternative solutions to conventional cemented carbide tools. This study examines the performance of such advanced tool materials in high speed finishing machining
In this paper, we discuss the apportionment of national debt when Ireland exited the UK in 1922. We estimate that the claim on Ireland amounted to 80 percent of Irish Gross National Product (G.N.P.) and describe how it was ultimately waived at the expense of an unchanged land border with Northern Ireland. While this represents the largest debt relief episode in the twentieth century, the political
This paper provides a consistent series for the Irish national debt since the foundation of the state. It also provides a continuous series for bond yields over the same period. The paper examines the factors behind the fluctuations in the debt burden over almost a century. The management of the debt burden by the Irish authorities has evolved over time, seeking to minimise both the burden on the
AIM: It has been suggested that intact cord resuscitation can reduce the risk of brain damage. We investigated the effects on neurodevelopment at two years of age.METHODS: This study was performed in Kathmandu, Nepal. In 2016, 231 late preterm and term infants born vaginally and not breathing were randomised to resuscitation with an intact cord or the standard practice of early cord clamping (CC).
We have developed MetaboKit, a comprehensive software package for compound identification and relative quantification in mass spectrometry-based untargeted metabolomics analysis. In data dependent acquisition (DDA) analysis, MetaboKit constructs a customized spectral library with compound identities from reference spectral libraries, adducts, dimers, in-source fragments (ISF), MS/MS fragmentation
