This experiment investigated the effect of tin in an amount up to 0·121 wt-% on the microstructure and mechanical properties of compacted graphite iron. Graphite and matrix evolution was emphasised with the help of scanning electron microscopy. The results indicate that Sn in experimental range reduces graphite size. Pearlite quantity would increase with the increasing Sn and reaches over 95% when
The dynamical evolution of globular clusters (GCs) is tied to their binary population, as binaries segregate to the cluster centre, leading to an increased binary fraction in the core. This central overabundance of mainly hard binaries can serve as a source of energy for the cluster and has a significant effect on the observed kinematics, such as artificially increasing the observed line-of-sight
Inflammatory airway diseases and lower respiratory tract infections are leading causes of severe illness, disability and death worldwide. Much of today´s hypotheses about the underlying inflammatory processes and pathogenic contribution by immune cells come from in vitro experiments or animal models. As a consequence, our knowledge of the actual immunopathological events in real patient tissues is
We use direct N-body simulations to explore some possible scenarios for the future evolution of two massive clusters observed towards the centre of NGC 4654, a spiral galaxy with mass similar to that of the Milky Way. Using archival HST data, we obtain the photometric masses of the two clusters, M = 3 × 105 M= and M = 1.7 × 106 M=, their half-light radii, Reff ∼4 pc and Reff ∼6 pc, and their proje
BACKGROUND: Due to demographic changes, hospital emergency departments in many countries are overcrowded. Internationally, several primary healthcare models have been introduced as alternatives to hospitalisation. In Norway, municipal acute wards (MAWs) have been implemented as primary care wards that provide observation and medical treatment for 24 h. The intention is to replace hospitalisation f
Dialogic resonance, when speakers reproduce constructions from prior turns, is a compelling type of coordination in everyday conversation. This study takes its starting point in resonance in stance-taking sequences with the aim to account for the interplay between intersubjective motivations and cognitive facilitation in resonance production. It analyzes stance-taking sequences in the London–Lund
Activated normal density granulocytes (NDGs) can suppress T-cell responses in a similar way as myeloid-derived suppressor cells (MDSCs). In this study, we tested the hypothesis that NDGs from blood and bone marrow of multiple myeloma (MM) patients have the ability to suppress T-cells, as MDSC. MM is an incurable plasma cell malignancy of the bone marrow. Like most malignancies, myeloma cells alter
The analysis of surface wave dispersion curves is a way to infer the vertical distribution of shear wave velocity. The range of applicability is extremely wide: going, for example, from seismological studies to geotechnical characterizations and exploration geophysics. However, the inversion of the dispersion curves is severely ill-posed and only limited efforts have been put in the development of
Zinc (Zn) is an important trace element that is essential for optimal plant growth. Zinc-solubilising bacteria can release Zn from its insoluble compounds. We isolated and identified Zn-solubilising bacteria (ZnSB) from the rhizosphere, and semi-quantitively and quantitatively evaluated their ability to dissolve various Zn minerals (ZnO, ZnCO3 and Zn3(PO4)2). Out of 24 rhizosphere soil samples, 15
Context: The Dyspnoea-12 (D-12) and Multidimensional Dyspnea Profile (MDP) were specifically developed for assessment of multiple sensations of breathlessness. Objectives: This systematic review aimed to identify the use and measurement properties of the D-12 and MDP across populations, settings and languages. Methods: Electronic databases were searched for primary studies (2008-2020) reporting us
In cancer tumor detection, tissue autofluorescence and characteristic features of injected hematoporphyrin derivative (HPD) can be utilized. The authors have studied the importance of the excitation wavelength for the achievable contrast between tumor and surrounding tissue using a rat tumor model. They have also compared the relative merits of two HPD preparations for tumor fluorescence detection
Abstract Hyponatremia is the most common electrolyte imbalance. It is associated with increased morbidity and in-hospital mortality. An effective early management is dependent on knowledge of epidemiology in the current population, accurate assessment of patient volume status and efficient diagnostic investigation. I) Prevalence of hyponatremia was investigated in an unselected population presenti
Forced migration has dramatically increased around the world during the last decade. Integration, including health and work among migrants, is an important topic in many European countries; thus, it is crucial to develop relevant approaches to address challenges that arise in tandem with migration and work. Nature-based intervention is one such approach that addresses different kinds of challenges
BACKGROUND: As under-5 mortality rates declined all over the world, the relative distribution of under-5 deaths during different periods of life changed. To provide information for policymakers to plan for multi-layer health strategies targeting child health, it is essential to quantify the distribution of under-5 deaths by age groups.METHODS: Using 245 Demographic and Health Surveys from 64 low-
Study region: Sixty-four river gauging stations distributed over Sweden. Study focus: To investigate the influence of climate teleconnection patterns (TP) on streamflow in Sweden. Streamflow data is regionalized and the average hydrographs of each homogeneous region is divided into hydrological seasons. Thereafter the impact of different TPs on the streamflow, per homogeneous region and per hydrol
Background: It has been shown that the socio-geographical environment of residential areas, such as altitude, affects the health status and health-maintenance behavior of residents. Here, we examined a hypothesis that altitude of residence would influence glycemic control in a general elderly population living in a rural area. Methods: A thousand and sixteen participants living in a mountainous re
Telomere erosion has been proposed to be tightly associated with senescence, environmental stressors and life history trade-offs. How telomere dynamics vary across life stages and especially in relation to (heritable) phenotypic traits is still unclear. The tawny owl Strix aluco display a highly heritable melanin-based colour polymorphism, a grey and a brown morph, linked to several fitness traits
The Supreme Leader of the Islamic Republic of Iran, Ali Khamenei, is 81 years old and reportedly in declining health. The question of the succession will be decided by the regime’s Assembly of Experts, who will choose the new Supreme Leader following Khamenei’s death. Six individuals have emerged as possible successors.
China’s unprecedented measures to mobilize its diverse surveillance apparatus played a key part in the country’s successful containment of the ongoing coronavirus pandemic. Critics worldwide believe these invasive technologies, in the hands of an authoritarian regime, could trample the right to privacy and curb fundamental civil and human rights. However, there is little domestic public resistance
