Calculated arterial blood gas values from a venous sample and pulse oximetry : Clinical validation

Background Arterial blood gases (ABG) are essential for assessment of patients with severe illness, but sampling is difficult in some settings and more painful than for peripheral venous blood gas (VBG). Venous to Arterial Conversion (v-TAC; OBIMedical ApS, Denmark) is a method to calculate ABG values from a VBG and pulse oximetry (SpO 2 ). The aim was to validate v-TAC against ABG for measuring

Towards equitable surgical systems : Development and outcomes of a national surgical, obstetric and anaesthesia plan in Tanzania

Despite emergency and essential surgery and anaesthesia care being recognised as a part of Universal Health Coverage, 5 billion people worldwide lack access to safe, timely and affordable surgery and anaesthesia care. In Tanzania, 19% of all deaths and 17 % of disability-adjusted life years are attributable to conditions amenable to surgery. It is recommended that countries develop and implement N

Study of the rare decays of B s 0 and B 0 mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector

A study of the decays B s 0 → μ + μ − and B 0 → μ + μ − has been performed using 26.3 fb −1 of 13 TeV LHC proton-proton collision data collected with the ATLAS detector in 2015 and 2016. Since the detector resolution in μ + μ − invariant mass is comparable to the B s 0 -B 0 mass difference, a single fit determines the signal yields for both decay modes. This results in a measurement of the branchi

Chiral perturbation theory and the evaluation of 1 Nc-corrections to nonleptonic decays

We present a discussion of the treatment of 1 Nc-corrections in chiral perturbation theory for nonleptonic weak processes. We compare the approach with an explicit cutoff and dimensional regularization in chiral perturbation theory and present evidence that they are equivalent. The quadratic dependence on the cutoff can be subtracted consistently at each level of 1 Nc. We discuss the identificatio

The chiral anomaly in non-leptonic weak interactions

The interplay between the chiral anomaly and the non-leptonic weak hamiltonian is studied. The structure of the corresponding effective lagrangian of odd intrinsic parity is established. It is shown that the factorizable contributions (leading in 1/Nc) to that lagrangian can be calculated without free parameters. As a first application, the decay K+→π+π0γ is investigated.

QCD aspects of leptoquark production at HERA

If a leptoquark is produced at HERA as a narrow resonance, various effects tend to broaden the measurable mass distribution considerably. These effects are discussed here, with special emphasis on initial- and final-state QCD radiation. A proper understanding is important to assess the significance of data and to devise strategies for better mass reconstruction.

Cyclohexane-Based Phosphinite Iridium Pincer Complexes : Synthesis, Characterization, Carbene Formation, and Catalytic Activity in Dehydrogenation Reactions

Metalation of two cyclohexane-based phosphinite pincer ligands, cis-POCyPO (4) and trans-POCyPO (5) (POCyPO = {1,3-bis-[(di-tert-butylphosphinito]cyclohexane}−), is reported. In line with previously published results (Dalton Trans. 2009, 8626, DOI: 10.1039/B910798C), ligand 4 undergoes aromatization to give benzene-based complex (POCOP)IrHCl (3) at high temperatures in the presence of [Ir(COD)Cl]2

Quality of life and tax legislation as an instrument for cultural policy goals, taking private patronage as an example

Historically, private initiative has always been of great significance for the arts. In most Europe-an countries the government took over from the private initiative after World War II. However, private initiative never completely disappeared, this is also true in the second half of the 20th century in which government subsidies were the dominant factor in the funding of the arts and cultural heri

Age, vulnerability and disability

This chapter is one of two theoretical pieces in this international collection. The aim is to challenge the traditional perception of who is a vulnerable person by discussing the concept from the vulnerability theory standpoint that basically accepts vulnerability as a universal state of being. It discusses the risk that the distribution of public services ends up being based on age absent conside

Monojets from new heavy vector bosons

A new scenario accounting for the production of monojets with large missing transverse energy is described and a specific model implementing it is constructed. The production rate for monojets is calculated.

Computational proteomics with Jupyter and Python

Proteomics based on mass spectrometry produces complex data in large quantities. The need for flexible computational pipelines, in the context of big data, in proteomics and other areas of science, has prompted the development of computational platforms and libraries that facilitate data analysis and data processing. In this respect, Python appears to be one of the winners among programming langua

Can we reduce the workload of mammographic screening by automatic identification of normal exams with artificial intelligence? A feasibility study

Purpose: To study the feasibility of automatically identifying normal digital mammography (DM) exams with artificial intelligence (AI) to reduce the breast cancer screening reading workload. Methods and materials: A total of 2652 DM exams (653 cancer) and interpretations by 101 radiologists were gathered from nine previously performed multi-reader multi-case receiver operating characteristic (MRMC

Hydrothermal carbon release to the ocean and atmosphere from the eastern equatorial Pacific during the last glacial termination

Arguably among the most globally impactful climate changes in Earth's past million years are the glacial terminations that punctuated the Pleistocene epoch. With the acquisition and analysis of marine and continental records, including ice cores, it is now clear that the Earth's climate was responding profoundly to changes in greenhouse gases that accompanied those glacial terminations. But the u

Lung function and bronchial responsiveness after Mycoplasma pneumoniae infection in early childhood

Mycoplasma (M.) pneumoniae has been associated with exacerbation of symptoms in asthmatic school children and adults; and an etiological role in asthma has been suggested. The purpose of this study was to investigate whether infection with M. pneumoniae in early childhood has a long-term influence on lung function and bronchial responsiveness. In a retrospective, clinical cohort-study children you

Students' explanation : Wider variety of teaching methods increases motivation and give higher results in biology

According to a previous study, results in one topic within an Upper Secondary School Biology course were increased due to student centered, formative working methods. The current study investigates student's perspective on the reasons for the observed increase in performance through focus group discussions. According to the findings, there was not a single factor explaining the increased result, b
