The composition was determined by microanalysis of energy dispersive X-ray (EDS) and X-ray fluorescence (XRF) indicating an excellent match between proposed and obtained compositions. Analysis of temperature-programmed reduction (TPR-H2) and AC impedance spectroscopy, confirmed the presence of relevant properties for use of these ceramics in
Clinical Use of Surface Electromyography to Track Acute Upper Extremity Muscle Recovery after Stroke: A Descriptive Case Study of a Single Patient

Arm recovery varies greatly among stroke survivors. Wearable surface electromyography (sEMG) sensors have been used to track recovery in research; however, sEMG is rarely used within acute and subacute clinical settings. The purpose of this case study was to describe the use of wireless sEMG sensors to examine changes in muscle activity during acute and subacute phases of stroke recovery, and understand the participant’s perceptions of sEMG monitoring. Beginning three days post-stroke, one stroke survivor wore five wireless sEMG sensors on his involved arm for three to four hours, every one to three days. Muscle activity was tracked during routine care in the acute setting through discharge from inpatient rehabilitation. Three- and eight-month follow-up sessions were completed in the community. Activity logs were completed each session, and a semi-structured interview occurred at the final session. The longitudinal monitoring of muscle and movement recovery in the clinic and community was feasible using sEMG sensors. The participant and medical team felt monitoring was unobtrusive, interesting, and motivating for recovery, but desired greater in-session feedback to inform rehabilitation. While barriers in equipment and signal quality still exist, capitalizing on wearable sensing technology in the clinic holds promise for enabling personalized stroke recovery.
Assessment of the Impairment in Domain functionalities and Executive Functions in Euthymic Patients, with Bipolar Disorder I/II - Utilizing the FAST and FAB tests

— Objective: In this article, we focus on assessing two key predictors of outcomes in Bipolar Disorder (BD): cognition and functionality performance, and researching for a correlation between them. Methods: Subjects were patients with BD in the euthymic phase (n=50), and healthy controls (n=25). Psychosocial functioning was evaluated using the Functioning Assessment Short Test (FAST), and the same group underwent the Frontal Assessment Battery (FAB) to assess the Executive Functions (EF). Clinical and sociodemographic characteristics were analyzed using one-way analysis of variance or the chi-square test. To verify a correlation between FAB and FAST tests, we used the Spearman Correlation Coefficient. Results: Patients with BD showed higher FAST total scores (24.60±11.09) than healthy controls (9.80±5.94) (p< 0.001), and patients with BD showed lower FAB total scores (13.56±2.81) than healthy control (15.72±1.64) (p<0.001). Associated with these results, bipolar patients showed higher FAST scores in all domains predominantly with moderate impairment (score 21-40), and also lower scores in the following three domains: conceptualization, sensitivity to interference, and inhibitory control in the FAST test (p<0.05). The correlation between the variables FAB and FAST presented a moderate intensity (r 2 = -0.539). Conclusion: This study reinforced the impact of BD in functionality and the EF, demonstrating alterations in several domains: social, occupational, and cognitive functions impairment. Understanding them is crucial for these patients, which increases the possibility of rehabilitation and the response to treatment.

On the Tortuosity-Connectivity of Porous Materials

In this work, the transport equations of ionic species in concrete are studied. First, the equations at the porescale are considered, which are then averaged over a representative elementary volume. The so obtained transport equations at the macroscopic scale are thoroughly examined and each term is interpreted. Furthermore, it is shown that the tortuosity-connectivity does not slow the average speed of the ionic species down. The transport equations in the representative elementary volume are then compared with the equations obtained in an equivalent pore. Lastly, comparing Darcy’s law and the Hagen-Poiseuille equation in a cylindrical equivalent pore, the tortuosity-connectivity parameter is obtained for four dierent concretes. The proposed model provides very good results when compared with the experimentally obtained chloride profiles for two additional concretes.
Characterization of Bacillus Species from Market Foods in Beijing, China

Foodborne diseases have been witnessing a constant rising trend worldwide, mainly caused by pathogenic microorganisms, such as Bacillus spp. , posing a direct threat to public health. The purpose of this study was to evaluate the biological risk of foodborne and probiotic Bacillus spp. in Beijing markets. A total of 55 Bacillus isolates, including 29 B. cereus, 9 B. licheniformis and 7 B. subtilis, mostly found in dairy products (32.7%), were recovered from 106 samples and identified by matrix-assisted laser desorption/ionization mass spectrometry and polymerase chain reaction methods. The susceptibility towards 16 antibiotics was determined using a broth microdilution method. Bacillus showed a high level of resistance to florfenicol (100%), lincomycin (100%), tiamulin (78.2%) and ampicillin (67.3%), while they were all susceptible or intermediate to vancomycin and rifampin. Additionally, we obtained the whole genome of 19 Bacillus strains using high-throughput sequencing, and the rates of resistance genes van, fosB, erm and tet were 57.9%, 57.9%, 21.1% and 26.3%, respectively. Moreover, 100%, 9.1%, 45.5% and 100% of these isolates carried virulence genes nhe, hbl, cytK and entFM, respectively. Lastly, 60% Bacillus strains were positive in hemolysis tests, and 3 B. licheniformis strains displayed an inhibitory activity on the growth of S. aureus ATCC 29213 using agar overlay technique. Our study outlines the characteristics of foodborne Bacillus spp. and provides information for the monitoring of food safety.
Plasmonic Enhancement of Photoactivity by Gold Nanoparticles Embedded in Hematite Films

Semiconducting n-type nanostructured hematite (α-Fe2O3) is a promising photocatalyst for solar water splitting because of its favorable band gap of 2.2 eV, low cost, and abundance in nature. However, its photoactivity is limited by the poor absorptivity and short hole diffusion length. Surface plasmon resonance (SPR) of metallic (Au, Ag, and Cu) nanostructures is known to concentrate and scatter incident light over a broad wavelength range and holds the promise of enhancing the light absorption cross section of a semiconducting material around the plasmonic structures. Herein we report enhanced photoelectrochemical (PEC) performance of a smooth chemical vapor deposited hematite film embedded with Au nanoparticles (NPs). About 3 times higher light absorption and photocurrent enhancement are obtained from thin hematite films containing Au NPs than with pristine hematite films. The plasmonic enhancement increases with the amount of Au NPs for the same thickness of hematite. Thickness-dependent study of photo.
A Fuzzy Lyapunov Function Method to Stability Analysis of Fractional-Order T–S Fuzzy Systems

This article investigates the stability analysis and stabilization problems for fractional-order T–S fuzzy systems via fuzzy Lyapunov function method. A membership-function-dependent fuzzy Lyapunov function instead of the general quadratic Lyapunov function is employed to obtain the stability and stabilization criteria. Different from the general quadratic Lyapunov function, the fuzzy Lyapunov functions contain the product of three term functions. Since the general Leibniz formula cannot be satisfied for fractional derivative, the current results on the fractional derivative for the quadratic Lyapunov functions cannot be extended to the fuzzy Lyapunov functions. Therefore, to estimate the fractional derivative of fuzzy Lyapunov functions, the fractional derivative rule for the product of three term functions is proposed. Based on the proposed fractional derivative rule, the corresponding stability and stabilization criteria are established, which extend the existing results. Finally, two simulation examples are presented to illustrate the effectiveness of the proposed theoretical analysis.
Simulated seasonal impact on middle atmospheric ozone from high-energy electron precipitation related to pulsating aurorae

Abstract. Recent simulation studies have provided evidence that pulsating aurorae (PsA) associated with high-energy electron precipitation is having a clear local impact on ozone chemistry in the polar middle mesosphere. However, it is not clear if PsA are frequent enough to cause longer-term effects of measurable magnitude. There is also an open question of the relative contribution of PsA-related energetic electron precipitation (PsA-EEP) to the total atmospheric forcing by solar energetic particle precipitation (EPP). Here we investigate the PsA-EEP impact on stratospheric and mesospheric odd hydrogen, odd nitrogen, and ozone concentrations. We make use of the Whole Atmosphere Community Climate Model and recent understanding onPsA frequency, latitudinal and magnetic local time extent, and energy-flux spectra. Analysing an 18-month time period cover-ing all seasons, we particularly look at PsA-EEP impacts at two polar observation stations located at the opposite hemispheres: Tromso in the NH and Halley in the SH. We find that PsA-EEP can have a measurable impact on ozone concentration above 30 km altitude, with ozone depletion by up to 8 % seen in winter periods due to PsA-EEP-driven NOx enhancement. We also find that direct mesospheric NOx production by high-energy electrons (E > 100 keV) accounts for about half of the PsA-EEP-driven upper stratospheric ozone depletion. A larger PsA-EEP impact is seen the SH where the background dynamical variability is weaker than in the NH. Clearly indicated from our results, consideration of polar vortex dynamics is required to understand PsA-EEP impacts seen at ground observation stations, especially in the NH. We conclude that PsA-EEP has potential to make an important contribution to the total EPP forcing, thus it should be considered in atmospheric and climate simulations.
The effect of uncertainty and outcome probability on non-instrumental information seeking

People’s desire to seek or avoid information is not only influenced by the possible outcomes of an event, but the probability of those particular outcomes occurring. There are competing explanations however as to how and why people’s desire for non-instrumental information is affected by factors including expected value, probability of outcome, and a unique formulation of outcome uncertainty. Over two experiments, we find that people’s preference for non-instrumental information is positively correlated with probability when the outcome is positive (i.e., winning money) and negatively correlated when the outcome is negative (i.e., losing money). Furthermore, at the aggregate level, we find the probability of an outcome to be a better predictor of information preference than the expected value of the event or its outcome uncertainty.

Outcomes After Proton Therapy Reirradiation for Malignant Glioma: Prospective Analysis of Over 100 Patients from the Proton Collaborative Group

Purpose: The optimal salvage treatment for malignant glioma after prior radiotherapy (RT) is not well established. Proton therapy (PT) is an attractive treatment modality for reirradiation (ReRT) of recurrent disease; however, data are limited.Methods: The prospective, multi-institutional Proton Collaborative Group (PCG) registry was queried for patients with malignant glioma who previously received RT and underwent PT-ReRT between 7/2011-10/2018. Overall survival (OS) and progression-free survival (PFS) were assessed using the Kaplan-Meier method and Cox proportional hazards regression analysis. Results: 109 consecutive patients were identified. Median follow-up was 11.2 months and median time interval (TI) from prior RT (median 59.3 Gy) to PT-ReRT (median 49.6 Gy) was 45.7 months. Primary histology was glioblastoma (n=62), oligodendroglioma (n=26), and astrocytoma (n=20). Median PFS and OS was 6.1 and 11.1 months, respectively. On UVA, improved PFS was associated with oligodendroglioma (HR 0.39) and astrocytoma (HR 0.55) histologies, WHO Grade III (HR 0.36), TI (HR 0.989), surgical resection (HR 0.39), and PT-ReRT dose ≥50 Gy (HR 0.59) (all p<0.03), while improved OS was associated with oligodendroglioma histology (HR 0.35), WHO grade III (HR 0.33), ECOG 0 (HR 0.47), TI (HR 0.985), and PT-ReRT dose ≥50 Gy (HR 0.58) (all p<0.04). Late Grade 3 toxicities occurred in 5.6% of patients with no attributable acute or late Grade 4-5 events.Conclusion: In the largest series of glioma PT-ReRT reported to date, retreatment appears well tolerated with acceptable outcomes and favorable toxicities compared to photon historical controls. Dose escalation achievable with PT may improve outcomes for well-selected patients.
Biodiesel Fuel from Waste Cooking Oil: A Cheaper and Cleaner Renewable Energy Source

Low cost, high fatty acid content waste cooking oil was transformed into biodiesel using an acid catalyzed chemical esterification reaction with 0.5 vol.% of H2SO4 at 60°C for 1h followed by the main transesterification reaction. For the purpose of comparison, biodiesel fuel was also prepared using straight vegetable oils (SVO’s). The gas chromatography test showed higher than 95% FAME (fatty acid methyl ester) content for different types of utilized feedstocks. Biodiesel fuel and its blends were characterized based on ASTM test methods to investigate its density, viscosity, flash point, pour point, heating value, and its cetane index and similar physical properties were obtained for all the prepared biodiesel fuels. B20 blend, which contains 20 vol.% of biodiesel and 80 vol.% of diesel, showed a better performance than B0 (100 vol.% of diesel) when tested in a laboratory compression ignition diesel engine. After simulation of the production process via Aspen Hysys, a feasibility study was conducted and the results revealed that utilizing waste cooking oils (WCO’s) as feedstock is more economical than starting with SVO’s as raw material.
Longitudinal Study on Seasonal Variation of Marine Biotoxins and Related Harmful Algae in Bivalve Mollusks Bred in Sardinia (Italy, W Mediterranean Sea) from 2015 to 2020 and Assessment of Potential Public Health Risks

Annual and interannual dynamics of shellfish toxins and associated harmful algal species (HAS) were analyzed from 2015 to 2020 in Tortolì Lagoon (Sardinia, west Mediterranean Sea). Analysis of seasonal occurrence of different harmful algae, such as Dinophysis spp. , Prorocentrum spp. , Pseudo-nitzschia spp. and Alexandrium minutum, was performed. The species Dinophysis acuminata and Dinophysis sacculus were responsible for the accumulation of lipophilic toxins belonging to the okadaic acid group (OAs) and pectenotoxins2 (PTX2) in bivalve mollusks. The highest HAS detection was recorded in the winter months; in particular, Dinophysis spp. was mostly present in January–February. Out of 1090 analyzed mollusk samples, 39 were non-compliant, exceeding the legal limits (160 μg OA eq/kg e.p.) reported in Regulation 853/2004 of the European Commission. A statistical analysis related to the presence of OA and PTX2 in mollusks with various environmental parameters (pH, water temperature, dissolved oxygen, algal density) was implemented, proving a clear winter seasonality. The present study highlights the necessity to better understand the different factors able to influence the production and accumulation of toxins in bivalve mollusks bred in an important Sardinian production area. The contribution of this research is important not only from an environmental and productive point of view but also from the view of implementing management in order to mitigate any harm to human health.

Embracing cultural relevance and fostering student metacognitive formative assessment through T.A.L.E. (Take Another Look Everyone) in a rural 5th grade math classroom: a collaborative action research project

ABSTRACT Many educators focus on the cognitive and/or cultural/contextual deficits that students bring to learning tasks, which are oftentimes used to explain poor academic performance. Metacognition that can be taught and learned for improving learning performance is regarded as an alternative. The purpose of this year-long collaborative action research is to describe how a culturally relevant metacognitive formative assessment strategy called TALE (Take Another Look Everyone) worked in a rural 5th grade mathematics classroom (N = 16). A variety of data was collected, recorded, co-transcribed, co-reflected, and systematically co-analyzed. Major findings were that students’ formative test scores substantially increased and two cases of students with different backgrounds, including Native American culture, and academic levels, demonstrated different ways of improving mathematics proficiency. This paper concluded that students learned better when given an opportunity to metacognitively think about mistakes in a highly respectful classroom.
Efficacy of Prophylactic Ketamine, Ondansetron, and Pethidine in Preventing Perioperative Shivering in Patients Undergoing Elective Knee Replacement Surgery Under Spinal Anaesthesia

Objective Perioperative shivering is a very common complication. Despite the vast array of knowledge regarding perioperative shivering and its after-effects, its prophylaxis is often overlooked. The study aims to compare the efficacy and safety of low-dose ketamine, ondansetron, and pethidine in the prevention of perioperative shivering in patients undergoing total knee replacement surgery under the subarachnoid block. Methods In this randomized controlled study, 203 patients aged 18-75 were included and allocated to one of the 4 groups; normal saline (group S), ondansetron 4 mg (group O), ketamine 0.25 mg kg−1 (group K), and pethidine 0.25 mg kg−1 (group P). Side effects, namely hypotension, nausea and vomiting, sedation, hallucinations, and respiratory depression were recorded. Results Perioperative shivering was present in 22 (44%), 8 (16%), 4 (7.84%), and 4 (7.69%) patients respectively in group S, O, K, and P, which was statistically significant when compared to group S with group K and P (P < .01). No difference in the incidence of hypothermia was observed across the groups (P < .17). A significantly lower incidence of hypotension was observed in group K. In group K, 5.9% of the patients were scored as being under severe sedation, according to the modified Wilson sedation scale. There was no incidence of hallucination or respiratory depression observed in any of the groups. Conclusions Patients undergoing total knee replacement surgeries are highly predisposed to the development of hypothermia. Temperature monitoring is thus imperative for all patients. Prophylactic administration of low-dose ketamine or ondansetron or low-dose pethidine produces a significant anti-shivering effect without any significant side effects. However, low-dose ketamine has the advantages of a lower incidence of hypotension, nausea, and vomiting than pethidine.
Coding Is Lit: Integrating Coding and Literacy in Early Childhood Inclusive Settings

There has been an increased emphasis in recent years on supporting young children with building 21st century literacy skills such as critical thinking and collaboration. Unfortunately, young children with or at risk for disabilities are unlikely to receive access to experiences that build 21st century literacies. Pre-coding activities, which include hands-on coding games and stories appropriate for young children, are one way to provide access to this population of students. The purpose of this article is to provide details about how educators in early childhood inclusive settings may integrate pre-coding activities with everyday routines and procedures as well as with common grade level appropriate read alouds. Fundamentals of pre-coding are provided along with guidelines for planning and instruction.
