Occurrence and recovery potential of rare earth elements in Finnish peat and biomass combustion fly ash
2019
Rare earth elements (REEs) are highly important in the modern society as a result of their wide use in various fields of industry. Their high supply risk and increase in demand has led to classification as critical materials, and consequently, new resources for REEs are being prospected widely. Coal fly ash has been suggested as a possible secondary resource for REEs, but very little information is available regarding REE occurrence in biomass or peat derived fly ash. In this paper, fly ash samples from commercial power plants using peat and biomass as fuel were studied for REEs. The average concentration of REEs was 530 ppm, with up to 920 ppm in one fly ash. Five out of seven fly ashes we…
Paediatric Sleep Questionnaire for Obstructive Sleep Apnoea Syndrome Screening: Is Sleep Quality Worthy of Note?
2021
Obstructive sleep apnoea syndrome (OSAS) is the most severe condition on the spectrum of sleep-related breathing disorders (SRBDs). The Paediatric Sleep Questionnaire (PSQ) is one of the most used and validated screening tools, but it lacks the comprehensive assessment of some determinants of OSAS, specifically anamnestic assessment and sleep quality. This study aims to assess the accuracy of some specific items added to the original PSQ, particularly related to the patient’s anamnestic history and to the quality of sleep, for the screening of OSAS in a paediatric population living in Sicily (Italy). Fifteen specific items, divided into “anamnestic” and “related to sleep quality” were added…
The Relationship Between a Baby's Age and Sleepiness in a Sample of Mothers
2021
One question of great practical importance for the parents, and especially the mother, after the birth of a baby, refers to how long the time during which they have to go with less and more fragmented sleep actually lasts. Most of the studies only explore this issue up to 6 months of the newborn's life, and less is known about the sleep problems the mothers may have after this initial period. The objective of this study is to examine the relationship between the sleep disruption and daytime sleepiness of mothers with infants until 2 years old compared to a group of women currently not at care of babies. To this end, a sample of 113 women, 67 currently bringing up a baby of under 2 years old…
Benefit of using an age-adjusted D-dimer cut-off
2015
Introduction: The association between a low-moderate pretest clinical probability and a negative D-dimer (DD) value is able to exclude the possibility of pulmonary embolism (PE). The value of DD seems to increase with age, reducing its specificity. Therefore, we intend to evaluate the usefulness of an age-adjusted cut-off value for age above 50 years, applying the formula suggested by Douma (age*10) set to our laboratory method (age*5) (1) . Patients and Methods: Observational, retrospective study from January to December 2011. DD test were performed to 1515 patients attended in the emergency room of our hospital according to the clinical suspicion made by the doctor who evaluated them. The…
Adaptation and Psychometric Properties of the Scale of Positive and Negative Experience (SPANE) in the General Colombian Population
2021
(1) Background: Diener’s Scale of Positive and Negative Experiences (SPANE) assesses the presence and intensity of positive and negative affects, since these are considered basic aspects of the study of well-being. This article studies its psychometric properties in the general Colombian population. (2) We conducted a cross-sectional study of a sample of 1255 Colombians and we used structural equation modeling to confirm the bifactor structure. Additionally, we studied invariance by gender, and convergent and concurrent validity. (3) We found acceptable fit indicators for the bifactor model (CFI = 0.889, RMSEA = 0.046, SRMR = 0.059) as well as for the convergent (CFI = 0.909, RMSEA = 0.050,…
Noninvasive respiratory support in the hypoxaemic peri-operative/periprocedural patient: A joint ESA/ESICM guideline.
2020
Hypoxaemia is a potential life-threatening yet common complication in the peri-operative and periprocedural patient (e.g. during an invasive procedure at risk of deterioration of gas exchange, such as bronchoscopy). The European Society of Anaesthesiology (ESA) and the European Society of Intensive Care Medicine (ESICM) developed guidelines for the use of noninvasive respiratory support techniques in the hypoxaemic patient in the peri-operative and periprocedural period. The panel outlined five clinical questions regarding treatment with noninvasive respiratory support techniques [conventional oxygen therapy (COT), high flow nasal cannula, noninvasive positive pressure ventilation (NIPPV) a…
Noninvasive Ventilation in the Perioperative Period
2019
High-flow nasal therapy (HFNT), as well as noninvasive ventilation (NIV), represents both noninvasive supports. HFNT is a ventilator support where humidified and heated gases are administered to the patient’s airways by a small nasal cannula at flow that reach up to 60 L/min. The delivered flow can be combined with oxygen providing different inspiratory oxygen fractions (FiO2). HFNT is increasingly used for critically ill adult patients in different clinical settings. Differently from noninvasive ventilation (NIV) which is intended to deliver intermittent positive pressure ventilation (NIPPV) or continuous positive airway pressure (CPAP) to the patient’s airway via different external interf…
Math homework : Parental help and children’s academic outcomes
2019
In the present study, we examined the longitudinal relations between child-perceived parental help with math homework (i.e., support and control), children's math skills, and mother-reported task persistent behavior in homework situations. A total of 624 mother–child dyads were followed across Grade 6 and Grade 9, controlling for Grade 3 variables. At each measurement point, children completed math tests, and their mothers evaluated task persistence during homework. In Grades 6 and 9, children reported their perceptions of their parents’ help with math homework. First, the results showed that perceived support in Grade 6 predicted an increase in persistence during homework in Grade 9. Secon…
Reconciling conflicting predictions about transience and persistence of management concepts in management fashion theory and new institutionalism
2021
PurposeAlthough drawing from neoinstitutional theoretical apparatus and ontology, management fashion theory is understood as a theory that explains the transitory nature of popular ideas and practices while institutional theory explains their stabilization, persistence and further institutionalization. In a nutshell, it seems that being opposed to each other, these two theories describe and predict different, incommensurable diffusion trajectories and organizational behaviour patterns. The purpose of this paper is to unify these two competing perspectives.Design/methodology/approachThis paper makes an attempt toward further unification of management fashion theory with new institutionalism …
Parametric nonlinear singular Dirichlet problems
2019
Abstract We consider a nonlinear parametric Dirichlet problem driven by the p -Laplacian and a reaction which exhibits the competing effects of a singular term and of a resonant perturbation. Using variational methods together with suitable truncation and comparison techniques, we prove a bifurcation-type theorem describing the dependence on the parameter of the set of positive solutions.
