The Influence of Age on Cerebral Tissue Oxygenation in Vasovagal Syncope and Orthostatic Hypotension

Age-related physiological impairment increases susceptibility to syncope. We tested the hypotheses that cerebral oxygenation during orthostatic provocation, as well as the level at which syncope occurs, differs according to age. Non-invasive hemodynamic monitoring and cerebral oximetry were applied during a head-up tilt test in 139 patients with vasovagal syncope (mean (SD) 45, (17) years, 60%-fem

Acute Hemodynamic Effects of Simultaneous and Sequential Multi-Point Pacing in Heart Failure Patients With an Expected Higher Rate of Sub-response to Cardiac Resynchronization Therapy : Results of Multicenter SYNSEQ Study

The aim of the SYNSEQ (Left Ventricular Synchronous vs. Sequential MultiSpot Pacing for CRT) study was to evaluate the acute hemodynamic response (AHR) of simultaneous (3P-MPP syn) or sequential (3P-MPP seq) multi-3-point-left-ventricular (LV) pacing vs. single point pacing (SPP) in a group of patients at risk of a suboptimal response to cardiac resynchronization therapy (CRT). Twenty five patient

Selection of Weather Files and Their Importance for Building Performance Simulations in the Light of Climate Change and Urban Heat Islands

Building performance predictions and their reliability rely heavily on weather data inputs. Climate is affected by spatial and temporal differences related to climate change and urban heat island effects, but the weather files used in building performance simulations (BPS) often remain unchanged and may represent weather observations generated from inadequate space and time for their application.

Reliability of data on percent consonants correct and its associated quality indicator in the Swedish cleft lip and palate registry

BACKGROUND: Data in national health care quality registries must be valid and reliable in order to enable open comparisons of results.AIM: To assess the reliability of data on percent consonants correct (PCC) and its associated quality indicator ≥86% correct consonants in the Swedish quality registry for patients born with cleft lip and palate (CLP) registry.METHODS: Six independent speech-languag

Inter-centre comparison of data on surgery and speech outcomes at 5 years of age based on the Swedish quality registry for patients born with cleft palate with or without cleft lip

BACKGROUND: The objective of the Swedish cleft lip and palate registry (CLP registry) is to promote quality control, research and improvement of treatment, by the comparison of long-term results. The aim was to compare data from the CLP registry among the six treatment centres, regarding data on surgery and speech outcomes at 5 years of age.METHODS: The participants were 430 children born in Swede

Three-dimensional time-lapse inversion of transient electromagnetic data, with application at an Icelandic geothermal site

Transient electromagnetic (TEM) is an efficient non-invasive method to map electrical conductivity distribution in the subsurface. This paper presents an inversion scheme for 3-D TEM time-lapse (TL) data using a generalized minimum support (MS) norm and its application to monitoring conductivity changes over time. In particular, two challenges for TL TEM applications are addressed: (i) the survey

Activation measures through the lens of governmentality

This article focuses on young unemployed in Sweden involved in two activation measures. Using the analytical framework of governmentality, it analyses how the participants perceive and value activation measures as government-driven intervention aimed at bringing young people into the labour market, based on a neoliberal discourse in the welfare state. The article highlights that the welfare system

EcoDesign and the Ten Golden Rules: Generic advice for merging environmental aspects into product development

The most important moment in product development is when demands and specifications are decided for the product that is being planned. The specification defines the goal for the product development process. It is a very important steering opportunity for the continuing work and for environmentally driven demands that are to be addressed in the product development phase. The designers are said to h

Functional Priorities in LCA and Design for Environment

Aim, Scope and BackgroundThe interest in environmental questions has increased enormously during the last decade. Environmental protection has become an issue of strategic importance within the manufacturing industry and many companies are now working in the field of Design for Environment (DFE). The main purpose of DFE is to create products and services for achieving a sustainable society. Design

BLOOD PRESSURE ADAPTATIONS AND ARTERIAL STIFFNESS IN THE GENERAL POPULATION

Objective: Arterial stiffness is independently associated with orthostatic hypotension (OH) in older individuals. The relationship between orthostatic blood pressure (BP) and arterial stiffness has not been thoroughly examined in the younger population. To investigate the relationship between orthostatic BP adaptations, central aortic hemodynamics, and arterial stiffness in the general population

Using Period Analysis to Timely Assess and Predict 5-Year Relative Survival for Liver Cancer Patients From Taizhou, Eastern China

Introduction: While timely assessment of long-term survival for patients with liver cancer is essential for the evaluation of early detection and screening programs of liver cancer, those data are extremely scarce in China. We aimed to timely and accurately assess long-term survival for liver cancer patients in eastern China.Methods: Patients diagnosed with liver cancer during 2004-2018 from four

The Influence of pH on the Lipase Digestion of Nanosized Triolein, Diolein and Monoolein films

Herein we studied the processes at the liquid aqueous interface at pH 7 and 8.5 during Thermomyces lanuginosus lipase-catalyzed hydrolysis of nanosized tri-, di- and mono-olein films deposited on a planar substrate. By employing a combination of ellipsometry, QCM-D and ATR-FTIR, we were able to reveal the physical properties of the thin films at high time resolution throughout the initial hydratio

Development and characterization of photovoltaic tandem-junction nanowires using electron-beam-induced current measurements

Nanowires have many interesting properties that are of advantage for solar cells, such as the epitaxial combination of lattice-mismatched materials without plastic deformation. This could be utilized for the synthesis of axial tandem-junction nanowire solar cells with high efficiency at low material cost. Electron-beam-induced current measurements have been used to optimize the performance of sing

Realization of axially defined GaInP/InP/InAsP triple-junction photovoltaic nanowires for high-performance solar cells

III-V semiconductor-based planar multi-junction solar cells synthesized to match the solar spectrum, increase absorption, and reduce thermalization loss are today's world-record efficiency solar cells. Realizing similarly performing multi-junction III-V nanowire (NW) solar cells would require significantly less material and is more sustainable at lower cost than planar solar cells. The NW geometry
