The emergence of the COVID-19 and its consequences has led to fears, worries, and anxiety among individuals worldwide. Recently, Ahorsu et al. (2020) developed the Fear of COVID-19 Scale (FCV-19S). The present study aimed to translate and validate the FCV-19S in Spanish university students. The sample comprised 606 Spanish´undergraduates with a mean age of 21.59 years old. We also used a six items from the State Trait Anxiety Inventory (STAI) by van Knippenberg, Duivenvoorden, Bonke & Passchiner (1990). The Fear of COVID-19 scale used for the present survey evidenced a good alpha measure of internal consistency or reliability analysis with ordinal alpha and ordinal omega. Seven items with acceptable corrected item-total correlation were retained and further confirmed by significant and strong factor loadings.  https://www.selleckchem.com/products/epoxomicin-bu-4061t.html  Concurrent validity was supported by the six items of the State Trait Anxiety Inventory (STAI). The Fear of COVID-19 Scale, a seven-item scale, has a stable unidimensional structure with robust psychometric properties. It is reliable and valid in assessing fear of COVID-19 among the Spanish university students.Physical activity (PA) practice can be a protective factor for anxiety-induced sleep disturbance (AISD), however the association between different contexts of PA and anxiety-induced sleep disturbance is not clear. We aimed to analyze the association between different contexts of PA and AISD. Data from the Brazilian School-based Health Survey [n=100,648; age 14.3y (range11-18 years)], conducted in 2015, were used. Higher PA during transport was associated with higher AISD. PA during physical education classes presented lower odds for AISD. PA practiced outside school was associated with reduced AISD among boys. The association between PA and AISD seems to be context-dependent.Research among adolescent samples has suggested patterns of change in suicidal ideation (SI) following psychiatric hospitalization discharge are heterogenous and predictive of subsequent suicide attempts. However, no studies have examined SI trajectories following discharge among adult samples or the effect of treatment on trajectories. We used growth mixture modeling to examine trajectories of SI among 152 active duty military personnel in a randomized controlled trial comparing brief cognitive-behavioral therapy (CBT) for suicide prevention to treatment as usual following discharge from inpatient psychiatric hospitalization for a suicide risk. Analyses of SI at baseline, 3-, 6-, and 12-months post-discharge among the full sample randomized to both conditions revealed two trajectories rapid improvers (59.21%) and gradual improvers (40.79%). Gradual improvers were more than twice as likely to attempt suicide in the two years following discharge. Exploratory analyses suggested that, relative to those in the treatment as usual condition, those randomized to brief CBT in both trajectories may be less likely to make a suicide attempt during the follow-up period. Results replicate and extend prior research in identifying distinct ideation trajectories following psychiatric inpatient hospitalization for suicide risk to active-duty personnel in a treatment trial and linking these trajectories to suicide attempts during follow-up.Green rusts (GRs) are redox active towards contaminants but they are not stable for long distance transport during the soil and groundwater remediation. In this study, green rust chloride (GR) was stabilized by selected regents, including silicate (Si), phosphate (P), fulvic acid (FA), carboxymethyl cellulose (CMC) and bone char (BC), then these stabilized GR, collectively named GR-X, would be further applied for Cr(VI) removal from aqueous solution. The stabilization experiment demonstrated that the release of Fe(II) from GR was effectively suppressed by above reagents, enabling at least 50% lower Fe(II) leaching from the stabilized GR-X than that from the pristine GR. The intact hexagonal GR plates and crystallinity were also confirmed by the SEM images and XRD patterns after storage for 7 days, indicating the stable structure of GR-X was remained. In the Cr(VI) removal tests, Cr(VI) was eliminated by GR-X in seconds with a Fe(II) utilization efficiency over 90%. The Cr species examination demonstrated that the GR-X was able to transfer Cr(VI) into stable Cr(III)-Fe(III) precipitates (Fe-Mn oxides fraction). After Cr(VI) removal tests, all reactors were exposed to the air for 1 week to monitor pH fluctuation and evaluated the risk of acidification. The results indicate that, except for GR-Si system, the other post-remediation systems are stable and the pH buffering ability of GR-X could avoid acidification and lower the Cr leaching risk.Data for source apportionment estimation was obtained from combustion of 11 types of biomass (rubber wood, palm kernel, palm fiber, sugarcane bagasse, sugarcane leaves, maize residue, rice stubble, rice straw, Xylocarpus moluccensis, Avicennia alba Blume and Rhizophora mucronata) and bituminous coal. Combustion was carried out in a tube furnace and emitted particulate matter (PM) was collected using a nanosampler that segregated particle sizes down to 0.1 μm. Emission factors of PM less then 0.1 μm were in the range of 0.11-0.28 g kg-1 (∼1-8% of total PM), except in the case of Rhizophora mucronata, which had an emission factor of 0.071 ± 0.004 g kg-1 (∼18% of total PM). The dominant polycyclic aromatic hydrocarbons (PAHs) found on PM less then 0.1 μm were chrysene from combustion of rubber wood, palm kernel, palm fiber, maize residue, Xylocarpus moluccensis, Avicennia alba Blume, Rhizophora mucronata and bituminous coal; benzo[b]fluoranthene from combustion of rice straw, sugarcane bagasse and sugarcane leaves; and benzo[k]fluoranthene from rice stubble combustion. The emission factors of PAHs bound to PM less then 0.1 μm from biomass combustion ranged from 0.005 to 0.044 mg kg-1 and the emission factor from bituminous coal combustion was 0.1411 ± 0.0004 mg kg-1. The carcinogenic potency equivalent or benzo[a]pyrene equivalent was highest from bituminous coal combustion (0.1252 mg kg-1) and between 0.0019 and 0.0192 mg kg-1 from biomass combustion. However, emission factors of both PM and particle-bound PAHs from biomass combustion were affected by moisture content of biomass and moisture contents of biomass used in this study were quite low, ranging from 0.165 to 0.863%.
