Study on the Dependence of Sun Protection Factor on Particle Size Distribution of Mica Using Gravitational Field-Flow Fractionation

Sunlight consists of beams of light of broad wavelength ranges, including infrared, visible, and ultraviolet (UV) radiation; X-rays; and γ-rays. Although the UV content of sunlight is relatively low, the human body, especially the human skin, is sensitive to UV rays. Mica is known to be effective in protecting the human skin from sunlight and reduces fine lines and pores on the skin. Mica is curre

Aortic vessel wall characteristics and blood pressure in children with intrauterine growth retardation and abnormal foetal aortic blood flow

Blood pressure and pulsatile diameter changes of the abdominal aorta were measured in 68 children (mean age 9 years), with varying degrees of intrauterine growth retardation who were previously examined in their intrauterine life with Doppler velocimetry of the thoracic descending aorta. Diastolic blood pressure was lower (p < 0.05) and pulse pressure was increased (p < 0.01) in children with a bi

Waveguide boundary spectral finite elements

A waveguide boundary spectral finite element method (SFEM) is developed for the study of acoustical wave propagation in non-uniform waveguide-like geometries. The formulation is based on a variational approach using a mixture of non-internal node element shape functions and wave solutions. The numerical method provides solutions to acoustic duct or fluid waveguide environments which may be divided

Implementation of Photovoltaic Systems for Net-Zero Energy Residential Buildings : Literature Review

Residential buildings consume up to 40% of total global energy production annually. Making the residential and commercial buildings less energy dependent is essential in reduction of greenhouse gas affects. One type of such buildings are known as Net-Zero Energy Building (ZEB). This paper introduces a summary of scholar works, which have been executed in the last decade to achieve Net-ZEB by using

Occupational exposure to nickel, cobalt, and chromium in the Lithuanian hard metal industry

Background: Metalworkers are said to have heavy exposure to metals, but the amount of released metal ions from alloys and deposition on the hands is unknown. Objective: To analyze nickel, cobalt, and chromium in vitro release to the artificial sweat from nails and wire made of different alloys, and to test metal deposition on the fingers of metalworkers. Material and Methods: Six different samples

Increasing climatic sensitivity of global grassland vegetation biomass and species diversity correlates with water availability

Grasslands are key repositories of biodiversity and carbon storage and are heavily impacted by effects of global warming and changes in precipitation regimes. Patterns of grassland dynamics associated with variability in future climate conditions across spatiotemporal scales are yet to be adequately quantified. Here, we performed a global meta-analysis of year and growing season sensitivities of v

Experiences of becoming widowed in old age–a cross-countries study with qualitative interviews from Denmark and quantitative measures of association in a Swedish sample

Purpose: Becoming widowed is a stressful health-threatening event causing major life changes. We explored how widowed people experience becoming widowed and examined if these experiences are quantitatively associated with widowhood. Methods: A multi-methods study using an exploratory sequential mixed-methods approach including a qualitative descriptive study with widowed people from Denmark and a

The importance of the longest R-R interval on 24-hour electrocardiography in mortality prediction in patients with atrial fibrillation

BACKGROUND: Heart rate control in atrial fibrillation (AF) is typically assessed by 24-hour electrocardiography (ECG). There are scarce data on the use of 24-hour ECG parameters to predict mortality in AF.AIMS: We aimed to identify 24-hour ECG parameters that predict mortality in AF.METHODS: We enrolled 280 ambulatory patients (mean [SD] age, 72.0 [8.7] years; 57.9% men) with permanent or persiste

HIP AND GROIN PROBLEMS IN THE PREVIOUS SEASON ARE ASSOCIATED WITH IMPAIRED FUNCTION IN THE BEGINNING OF THE NEW SEASON AMONG PROFESSIONAL FEMALE ICE HOCKEY PLAYERS - A CROSS SECTIONAL STUDY

Background: Hip and groin problems are common in ice hockey but studies on professional female players are sparse. The available literature describes hip and groin problems by reporting incidence of time-loss injuries and may thereby underestimate the scope of these problems, which are often due to overuse and may not lead to absence from ice hockey participation.Purpose: The purpose of this study

Software Ticks Need No Specifications

Software bugs cost time, money, and lives. They drive software research and development efforts, and are central to modern software engineering. Yet we lack a clear and general definition of what bugs are. Some bugs are defects, clearly defined as failures to meet some requirement or specification. However,there are many forms of undesirable program behaviour that are completely compatible with a

Optimization of the Dental Direct Digital Imaging by Applying the Self-Recognition Technology

This paper is intended to introduce the technology to solve some of the deficiencies of the direct digital radiology. Nowadays, digital radiology is the latest progression in dental imaging, which has become an essential part of dentistry. There are two main parts of the direct digital radiology comprised of an intraoral X-ray machine and a sensor (digital image receptor). The dentists and the den

The Origin of Neptune's Unusual Satellites from a Planetary Encounter

The Neptunian satellite system is unusual, comprising Triton, a large (∼2700 km) moon on a close-in, circular, yet retrograde orbit, flanked by Nereid, the largest irregular satellite (∼300 km) on a highly eccentric orbit. Capture origins have been previously suggested for both moons. Here we explore an alternative in situ formation model where the two satellites accreted in the circum-Neptunian d

Atomic data for the Gaia-ESO Survey

Context. We describe the atomic and molecular data that were used for the abundance analyses of FGK-type stars carried out within the Gaia-ESO Public Spectroscopic Survey in the years 2012 to 2019. The Gaia-ESO Survey is one among several current and future stellar spectroscopic surveys producing abundances for Milky-Way stars on an industrial scale. Aims. We present an unprecedented effort to cre

Transnational Solidarity : Concept, Challenges and Opportunities

The book analyses the concept and conditions of transnational solidarity, its challenges and opportunities, drawing on diverse disciplines as Law, Political Science, Sociology, Philosophy, Psychology and History. In the contemporary world, we see two major opposing trends. The first involves nationalistic and populistic movements. Transnational solidarity has been under pressure for a decade becau

Sound transmission through inhomogeneous waveguides

A spectral element method is described which enables reduced wave equation problems defined in regular, arbitrary length regions to be solved as a set of coupled problems over neighbouring domains. A combination of trial functions are considered, namely the specific eigenfunctions of a differential operator and a set of hierarchical polynomials. The coefficients in the representation of the acoust

Contrasting prenatal nutrition and environmental exposures in association with birth weight and cognitive function in children at 7 years

Background Good nutrition is essential for individual health, a notion that is particularly true during pregnancy. We have used a nutrition index that measures the adequacy of one's diet relative to the unique nutritional needs of individuals due to, for example, their activity level, dietary restrictions, lifestyle and body size. The use of this personalised metric of dietary nutritiousness in th

Coping with tensions between standardization and individualization in social assistance

Today’s ambition to adapt and individualize welfare delivery poses a challenge to human service organizations at the same time seeking to standardize clients, with consequences for street-level bureaucrats. In this article, the implementation of an instrument for standardized assessment of income support (IA) in Swedish social services is used to investigate what strategies street-level bureaucrat

Ontogeny of vesicular monoamine transporter mRNAs VMAT1 and VMAT2. I. The developing rat central nervous system

We used in situ hybridization histochemistry to study the expression of the mRNA of the two vesicular monoamine transporters (VMAT1 and VMAT2) during embryonic and postnatal development of the central nervous system (CNS) int he rat. In the adult rat, VMAT2 mRNA is present exclusively in monoaminergic cell groups of the CNS and VMAT1 mRNA was reported to be present in the adrenal medulla and certa

Low-density lipoprotein cholesterol reduction and statin intensity in myocardial infarction patients and major adverse outcomes : A Swedish nationwide cohort study

Aims: Clinical trials have demonstrated that a reduction in low-density lipoprotein cholesterol (LDL-C) reduces cardiovascular (CV) events. This has, however, not yet been shown in a real-world setting. We aimed to investigate the association between LDL-C changes and statin intensity with prognosis after a myocardial infarction (MI). Methods and results: Patients admitted with MI were followed fo
