Performance and wear mechanisms of PCD and pcBN cutting tools during machining titanium alloy Ti6Al4V
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
Till Debt Do Us Part : Financial implications of the divorce of the Irish Free State from the United Kingdom, 1922–1926
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
Managing a Century of Debt
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
Neurodevelopmental outcomes of a randomised trial of intact cord resuscitation
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).
MetaboKit : a comprehensive data extraction tool for untargeted metabolomics
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
The common place of rape : Challenging borders of disciplines and continents through research
During the #metoo movement in the autumn of 2017, stories about sexual assault, including rape, garnered much attention worldwide. It might seem as if all of these stories came from nowhere. In fact, during the last decades several rape cases have been highlighted and debated in media all over the world. These discussions in the media and among the general public have led to scrutiny and a critica
Impedimetric melanoma invasion assay device using a simple paper membrane and stencil-printed electrode on PMMA substrate
The transwell assay is currently the most popular approach to studying cellular invasion due to its ease of use and readout, and the possibility for quantitative measurements. However, it only allows end-point measurements without the possibility for real-time tracking of the dynamics of cell movement during an invasion. Moreover, it requires cell labeling, and construction of customized devices i
Effects of different injection strategies on ignition and combustion characteristics in an optical PPC engine
Although multiple injection strategies have a significant influence on partially premixed combustion (PPC) efficiency, the mechanisms behind the influence are still to be explained and evaluated. In this paper, single, double, and triple injection strategies are used in a heavy-duty optical engine. The effects on engine efficiency are analyzed by an energy balance method. Furthermore, the change o
Suicide mortality after discharge from inpatient care for bipolar disorder : A 14-year Swedish national registry study
Bipolar disorder has long been associated with increased risks for suicidality; though factors associated with dying by suicide remain obscure. Here, we retrospectively examine the associations between the different phases of bipolar illness and other common comorbidities with death by suicide in the 120 days following each discharge for Swedes first admitted as inpatients for bipolar disorder dur
Intensive Care Unit Delirium, Clinical Observations, and Patients' Statements : A Case Study
BACKGROUND: In clinical practice, nurses use their clinical gaze and make observations in order to assess patients' medical conditions and care needs. However, signs of developing intensive care unit delirium (ICUD) are often difficult to determine, as communication with patients is usually limited because of intubation and the seriousness of their medical condition(s). Usually, ICUD is screened a
Antibiotic containing bone cement in prevention of hip and knee prosthetic joint infections : A systematic review and meta-analysis
Background: Prosthetic joint infection (PJI) is the most serious total joint arthroplasty (TJA) complication despite several aseptic and antiseptic preventive measures. There is no clear evidence or even consensus, whether antibiotic-loaded bone cement (ALBC) should be used, in addition to systemic short-term routine antibiotic prophylaxis, to reduce the risk of PJI in primary TJA. We aimed to ana
Forces in circular motion : Discerning student strategies
Students often use incoherent strategies in their problem solving involving force and motion, as revealed, e.g. when they are asked to draw force diagrams for amusement rides involving circular motion, whether in horizontal or vertical planes. Depending on the questions asked, assignments involving circular motion can reveal different types of more or less correct and coherent strategies used by t
Anti-Aliasing method for ultrasonic 2D phase-sensitive motion estimator
A 2D motion estimator can estimate tissue motions and blood flow dynamics more accurately than a 1D motion estimator. In this study, we proposed a simple anti-Aliasing filter to unwrap the phase of the cross spectrum. The proposed method is evaluated by simulation mimicking steady flows, and the magnitude of the true velocity was changed from 200 to 2400 mm s-1. In the simulation, bias error was i
Impact of nasal resistance on the distribution of apneas and hypopneas in obstructive sleep apnea
Background: This study aims to investigate how increased nasal resistance affects respiratory variables in obstructive sleep apnea (OSA). In this setting, to assess how nasal resistance, as measured by 4-phase rhinomanometry, affects the distribution of hypopneas and apneas when measured with routine Sleep Polygraphy (PG). Methods: PG recordings were analysed and 4-phase rhinomanometry was conduct
The transcription factor ANAC017 is a key regulator of mitochondrial proteotoxic stress responses in plants
Impaired mitochondrial translation or reduced mitochondrial protein import can lead to imbalances in mitochondrial protein composition. Such mitochondrial proteotoxic stresses can trigger a nuclear transcriptional response commonly described as the mitochondrial unfolded protein response (UPRmt). Despite extensive studies of UPRmt pathways in animal and fungal systems, very little is known about h
Joint inhibition of mitochondrial complex IV and alternative oxidase by genetic or chemical means represses chloroplast transcription in Arabidopsis
Changes in the functional state of mitochondria have profound effects on other cellular compartments. Genome-wide expression analysis of Arabidopsis rps10 mutants with an RNAi-silenced expression of mitoribosomal S10 protein has revealed extensive transcriptional reprogramming. A meta-analysis comparing expression datasets of 25 mitochondrial perturbations showed a high similarity of the aox1a:rpo
Retrograde signals from endosymbiotic organelles : A common control principle in eukaryotic cells
Endosymbiotic organelles of eukaryotic cells, the plastids, including chloroplasts and mitochondria, are highly integrated into cellular signalling networks. In both heterotrophic and autotrophic organisms, plastids and/or mitochondria require extensive organelle-to-nucleus communication in order to establish a coordinated expression of their own genomes with the nuclear genome, which encodes the

Elucidating failure mechanisms in human femurs during a fall to the side using bilateral digital image correlation
An improved understanding of the mechanical properties of human femurs is a milestone towards a more accurate assessment of fracture risk. Digital image correlation (DIC) has recently been adopted to provide full-field strain measurements during mechanical testing of femurs. However, it has typically been used to measure strains on the anterior side of the femur, whereas in both single-leg-stance
