Comparing two objects falling together is a small-scale version of Galileo’s classical experiment, demonstrating the equivalence between gravitational and inertial mass. We present here investigations by a group of ten-year-olds, who used iPads to record the drops. The movie recordings were essential in the follow-up discussions, enabling the students to compare the different situations and to dis

Introduction: Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is an emerging minimally invasive option for pathologic examination of intrathoracic lymphadenopathy as well as for staging lung cancer. Objectives: To evaluate the diagnostic yield and possible learning curve effects on diagnostic performance using EBUS-TBNA in mediastinal lymphadenopathy. Methods: A retrospective

We consider the authentication problem, using the model described by Simmons. Several codes have been constructed using combinatorial designs and finite geometries. We introduce a new way of constructing authentication codes using LFSR-sequences. A central part of the construction is an encoding matrix derived from these LFSR-sequences. Necessary criteria for this matrix in order to give authentic

OBJECTIVE: The incidence of myocardial infarction (MI) has decreased in general but not among younger middle-aged adults. We performed a cohort study of the association between neighbourhood socioeconomic status (SES) at the age of 40 and risk of MI before the age of 50 years. METHODS: All individuals in Sweden were included in the year of their 40th birthday, if it occurred between 1998 and 20

OBJECTIVE: The main objective of this study was to investigate possible predictors of response to cholinesterase inhibitor (ChEI) treatment, including pre-treatment progression rates and levels of the cerebrospinal fluid (CSF) biomarkers. A secondary objective was to evaluate whether treatment with ChEI changed progression. METHODS: Out-patient individuals (n = 191) with the clinical diagnosis of

This paper investigates the relationship between anticipation that employers may discriminate against certain people (not specified, but not specifically the respondent) according to race, colour of skin, religion or cultural background, and self-rated health, adjusting for social capital in the form of generalised (horizontal) trust in other people. It also investigates ethnic differences in anti

A growing public awareness of the potential negative impacts of corporate activities on the natural environment and society compels large companies to invest increasing resources in the communication of their responsible conduct. This article employs Appraisal theory in a comparative analysis of BP’s and IKEA’s 2009 social reports, each company’s record of their non-financial performance. The main

OBJECTIVE:: To evaluate the prognostic implication of changes in postoperative B-type natriuretic peptide (BNP) concentrations in patients undergoing cardiopulmonary bypass for cardiac surgery. DESIGN:: A retrospective analysis of prospectively collected clinical data. SETTING:: Cardiothoracic surgery and an intensive care unit (ICU) in a university hospital. PARTICIPANTS:: The present study inclu

PURPOSE: To report an alternative to the fenestrated stent-graft for preserving blood flow to side branches in the sealing zones of aortic stent-grafts. TECHNIQUE: A covered stent is deployed parallel to the main aortic stent-graft, protruding somewhat proximally, like a chimney, to preserve flow to a vital side branch covered by the aortic stent-graft. Use of a chimney graft makes it possible to

AimTo assess the prevalence, types and indications for fluid bolus therapy in neonates with haemodynamic compromise.MethodsThis was a pragmatic, international, multicentre observational study in neonatal units across Australasia, Europe and North America with a predefined study period of 10–15 study days per participating neonatal unit between December 2015 and March 2017. Infants ≤28 days of age

In order to investigate the relation between literature and television, one must consider how the influence goes both ways. The chapter accordingly investigates how contemporary literature reflects on, imitates and remediates modern television series. Drawing on theoretical approaches by Jim Collins and Jason Mittell, I analyse Mark Z. Danielewski’s serial novel The Familiar, which mimics and invo
