Fragmentation of relativistic nuclei in the α-particle model

We investigate reactions between high-energy oxygen and carbon nuclei and various nuclear targets. The beam nucleus is described by an α-particle model and the reaction products are classified into groups corresponding to inelastic collisions of one, two, three and four alpha particles. Excellent agreement with experiment is obtained.

Use of the drop volume of amniotic fluid in estimating the risk for respiratory distress syndrome in the newborn infant

The present study describes the testing and function of the drop-volume method in the analysis of fetal lung maturity with use of amniotic fluid. Elevated surface tension resulting from a lack of surface-active phospholipids (surfactant) is the primary etiologic defect in the development of respiratory distress syndrome. The drop-volume method quantifies the surface tension of amniotic fluid with

Effect of second-trimester sonographic cervical length on the risk of spontaneous preterm delivery in different risk groups : A prospective observational multicenter study

Introduction: The aim of the study is to compare the effect of cervical length measured with transvaginal ultrasound in the second trimester on the risk of spontaneous preterm delivery (PTD) between different risk groups of asymptomatic women with a singleton pregnancy. Material and methods: This is a pre-planned exploratory analysis of the CERVIX study, a prospective blinded multicenter diagnosti

Good People Doing Bad Things: Compliance Regimes in Organizations

Nearly all major corporations and many public agencies have established ethics and compliance departments, some of them as the result of penalties imposed by the US Dept. of Justice, others due to embarrassing scandals. The responsibilities of these ethics and compliance departments range from inculcating internal codes of conduct within the organization, preventing bribery in contracts, impeding

Landscapes of Indignation: Denunciations of Tax Evaders and Welfare Cheaters in Scandinavia

Abstract: Citizen-state relations can be more than just a political relationship. It can also be emotional. Where there is an articulated balance between citizen tax obligations and state welfare services, there arises a combination of redistribution and reciprocity between citizen and state. This fiscal compact has an emotional component. This emotional component becomes indignation when people p

Search for trilepton resonances from chargino and neutralino pair production in s =13 TeV pp collisions with the ATLAS detector

A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an R-parity-violating coupling into a lepton and a W, Z, or Higgs boson. The trilepton invariant-mass spectrum is constructed from events with three or more leptons, targeting chargino decays that include an electron or muon and a leptonically

Search for charged Higgs bosons decaying into a top quark and a bottom quark at √s = 13 TeV with the ATLAS detector

A search for charged Higgs bosons decaying into a top quark and a bottom quark is presented. The data analysed correspond to 139 fb−1 of proton-proton collisions at s = 13 TeV, recorded with the ATLAS detector at the LHC. The production of a heavy charged Higgs boson in association with a top quark and a bottom quark, pp → tbH+ → tbtb, is explored in the H+ mass range from 200 to 2000 GeV using fi

Assessment of mobile radiometry data in radiological emergencies using Bayesian statistical methods

Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. As a result, significant areas are still contaminated with some residential areas evacuated.

European PanCareFollowUp Recommendations for surveillance of late effects of childhood, adolescent, and young adult cancer

Background: Long-term follow-up (LTFU) care for childhood, adolescent, and young adult (CAYA) cancer survivors is essential to preserve health and quality of life (QoL). Evidence-based guidelines are needed to inform optimal surveillance strategies, but many topics are yet to be addressed by the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG). Therefore, the Pan

Sulfidic anoxia in the oceans during the Late Ordovician mass extinctions – insights from molybdenum and uranium isotopic global redox proxies

The Late Ordovician Mass Extinction wiped out 85% of animal species in two phases (LOME1 and LOME2). The kill mechanisms for the extinction phases are debated, but deteriorating climate and the expansion of marine anoxia appear to have been important factors. Nevertheless, the spatial extent and intensity of marine anoxia and its temporal relationship with the extinctions are not well understood.

Microstructural heterogeneity of the collagenous network in the loaded and unloaded periodontal ligament and its biomechanical implications

The periodontal ligament (PDL) is a highly heterogeneous fibrous connective tissue and plays a critical role in distributing occlusal forces and regulating tissue remodeling. Its mechanical properties are largely determined by the extracellular matrix, comprising a collagenous fiber network interacting with the capillary system as well as interstitial fluid containing proteoglycans. While the phas

Non-invasive quantification of pressure-volume loops from cardiovascular magnetic resonance at rest and during dobutamine stress

Non-invasive quantification of pressure-volume (PV) loops from brachial pressure and cardiovascular magnetic resonance is a validated method but its application has been limited to resting heart rates. The aim of this study was to improve the previous method and validate it against invasive left-ventricular pressure measurements in an experimental porcine model, and further apply it to 16 healthy

Content-specific vulnerability of recent episodic memories in Alzheimer's disease

Endel Tulving's episodic memory framework emphasizes the multifaceted re-experiencing of personal events. Indeed, decades of research focused on the experiential nature of episodic memories, usually treating recent episodic memory as a coherent experiential quality. However, recent insights into the functional architecture of the medial temporal lobe show that different types of mnemonic informati

Municipal climate mitigation policy and policy learning - A review

Cities are expected to contribute to climate mitigation by providing effective climate policy actions in a multilevel governance context. Yet, it is unclear what we actually know about the strengths and weaknesses of urban climate policy measures and how municipal policy learning could be enhanced. In this article we present a comprehensive review on cities’ experience in climate mitigation policy

A global review of marine air pollution policies, their scope and effectiveness

Shipping is associated with various environmental impacts, such as pollutants discharged to air and sea. Much of this pollution appears to be unregulated, and global emissions from shipping are expected to more than triple between 2020 and 2050. This paper reviews global, national, regional and port-level legislative approaches that have been implemented to reduce emissions of carbon dioxide (CO2)

Rapid personalized AMR diagnostics using two-dimensional antibiotic resistance profiling strategy employing a thermometric NDM-1 biosensor

Antimicrobial resistance (AMR) threatens global public health and modern surgical medicine. Expression of β-lactamase genes is the major mechanism by which pathogens become antibiotic resistant. Pathogens expressing extended spectrum β-lactamases (ESBL) and carbapenemases (CP) are especially difficult to treat and are associated with increased hospitalization and mortality rates. Despite considera

Postural orientation, what to expect in youth athletes? A cohort study on data from the Malmö Youth Sport Study

Background: Studies investigating postural orientation in uninjured youth athletes are scarce. Understanding how postural orientation during functional performance tests change with age in uninjured athletes has the potential to enhance awareness of changes in performance after injury and to set realistic goals for injured athletes. Thus, the aim of this study was to explore postural orientation d

The non-saying of what should have been said

According to Grice’s analysis, conversational implicatures are carried by the saying of what is said (Grice 1989: 39). In this paper, it is argued that, whenever a speaker implicates a content by flouting one or several maxims, her implicature is not only carried by the act of saying what is said and the way of saying it, but also by the act of non-saying what should have been said according to wh
