Four Weeks of 16:8 Time-Restricted Feeding on Stress, Sleep, Quality of Life, Hunger Level, and Body Composition in Healthy Adults: A Pilot Study on Wellness Optimization

Introduction: Sustainable methods of dietary lifestyle changes are essential to long term weight loss maintenance and enhancement in overall health and wellness A novel modified alternative method to caloric restriction is Time-Restricted Feeding (TRF), a sub-type of Intermittent Fasting. The purpose of this pilot study was to determine the effect of four weeks of TRF (without caloric deficit) on body composition, stress levels, sleep quality, hunger level, and quality of life. Methods: Sixteen participants, 9 males and 7 females, mean age 34.0 ± 11.7 years, completed the four-week protocol. Fasting program was 16 hours from the time of last meal of the evening to start of first meal the following day. Participants were required to consume their normal daily caloric intake within an 8-hour period. Results: There were significant reductions in mean body fat percentage (26.2±2.4 vs. 25.5±2.6, p=0.01), visceral fat (cm2) (98.2±15.3 vs. 94.1±15.7, p=0.003), body fat mass (kg) (21.6±3.0 vs. 21.0±3.2, p= 0.02), trunk fat (kg) (11.5±1.6 vs. 11.0±1.6, p=0.001) and stress levels (14.1±1.9 vs. 11.0±1.4, p=0.03). There was a significant drop in hunger levels over time (χ2 = 16.4, p=0.001). There were no significant changes in sleep quality or quality of life. Conclusion: TRF may be an effective option to decrease stress, body fat, visceral fat, and obesity-related diseases while not disrupting sleep quality and Quality of Life. Our pilot study demonstrated potential health benefits that could be incorporated by healthcare workers into whole-person wellness programs.
Algae-Assisted Microbial Desalination Cell: Analysis of Cathode Performance and Desalination Efficiency Assessment

Algae-assisted microbial desalination cells represent a sustainable technology for low-energy fresh water production in which microalgae culture is integrated into the system to enhance oxygen reduction reaction in the cathode chamber. However, the water production (desalination rate) is low compared to conventional technologies (i.e., reverse osmosis and/or electrodialysis), as biocathodes provide low current generation to sustain the desalination process. In this sense, more research efforts on this topic are necessary to address this bottleneck. Thus, this study provides analysis, from the electrochemical point of view, on the cathode performance of an algae-assisted microbial desalination cell (MDC) using Chlorella vulgaris. Firstly, the system was run with a pure culture of Chlorella vulgaris suspension in the cathode under conditions of an abiotic anode to assess the cathodic behavior (i.e., cathode polarization curves in light-dark conditions and oxygen depletion). Secondly, Geobacter sulfurreducens was inoculated in the anode compartment of the MDC, and the desalination cycle was carried out. The results showed that microalgae could generate an average of 9–11.5 mg/L of dissolved oxygen during the light phase, providing enough dissolved oxygen to drive the migration of ions (i.e., desalination) in the MDC system. Moreover, during the dark phase, a residual concentration of oxygen (ca. 5.5–8 mg/L) was measured, indicating that oxygen was not wholly depleted under our experimental conditions. Interestingly, the oxygen concentration was restored (after complete depletion of dissolved oxygen by flushing with N2) as soon as microalgae were exposed to the light phase again. After a 31 h desalination cycle, the cell generated a current density of 0.12 mA/cm2 at an efficiency of 60.15%, 77.37% salt was removed at a nominal desalination rate of 0.63 L/m2/h, coulombic efficiency was 9%, and 0.11 kWh/m3 of electric power was generated. The microalgae-assisted biocathode has an advantage over the air diffusion and bubbling as it can self-sustain a steady and higher concentration of oxygen, cost-effectively regenerate or recover from loss and sustainably retain the system’s performance under naturally occurring conditions. Thus, our study provides insights into implementing the algae-assisted cathode for sustainable desalination using MDC technology and subsequent optimization.
Factors Affecting Post-Stroke Depression in Acute Ischemic Stroke Patients after 3 Months

Post-stroke depression (PSD) affects approximately one-third of stroke patients. PSD not only impairs recovery and lowers quality of life, but has also serious neurological consequences, high mortality, and stroke recurrence risks. Studies on PSD-related prognostic factors are still lacking, especially environmental factors. Moreover, relieving factors after PSD in stroke patients has not been reported. This study aimed to investigate (study design 1) risk factors for PSD diagnosis after three months, and (study design 2) related factors for the relieving of early PSD after three months. This retrospective study included 227 patients hospitalized for acute ischemic stroke within three days at Jeonbuk National University Hospital from January to December 2019. The depressive status was assessed using the Hamilton Depression Rating Scale (HDRS) at admission and after three months. Clinical and laboratory data were analyzed for relevant prognostic factors. (Study design 1) HDRS score at admission (adjusted odds ratio (aOR) 1.22, 95% confidence interval (CI) 1.14–1.31; p < 0.001) and hospitalization period (aOR 1.11, 95% CI 1.02–1.20; p = 0.013) were confirmed as prognostic factors of PSD after three months. (Study design 2) The National Institute of Health Stroke Scale (NIHSS) score at discharge (aOR 0.80, 95% CI 0.68–0.94; p = 0.006) and HDRS score at admission (aOR 0.80, 95% CI 0.71–0.89; p < 0.001) were confirmed as prognostic factors of depression improvement after three months. In conclusion, environmental factors such as hospitalization period could be important in managing PSD. Factors related to PSD improvement are expected to be helpful in establishing a strategy for PSD recovery.

Counter-storytelling, metaphors, and rhetorical questioning: discursive strategies of advocacy toward racial equity in school board meetings

ABSTRACT Minoritized communities have long engaged in collective resistance against racism and other forms of injustice in schools. In this article, we highlight the discursive strategies of one such case of resistance during official public comments in a series of school board meetings over nine months. Specifically, we identify how community advocates used metaphors, counter-storytelling, and rhetorical questioning to speak out against racism directed largely at Black students in a majority white school district in the US Southwest. We conclude with implications for other communities to consider these strategies in their own resistance and for educators to take seriously the discourse of minoritized communities.
Average Strain Rate In The Italian Crust Inferred From A Permanent GPS Network

SUMMARY High-quality, weekly solutions for the coordinates of 45 permanent GPS stations spanning 1–6 years and covering the Alpine Mediterranean area are used to estimate a horizontal velocity field aligned with the ITRF2000 velocity datum. After subtracting model velocities for the Eurasian Plate, we show that the residual velocity field north of the Apennines, in the Adriatic/Dinaric region, describes a NNE-trending tectonic flow with a negative velocity gradient, from 6 mm yr−1 NE of the Apennines to virtually zero NE of the Dinarids. In the Calabria region we observe a divergent pattern, with NNW orientation, which turns to west as one moves north, towards Tuscany. Very small residual velocities are observed for stations in the Sardinia Corsica block, Spain, Southern France and north of the Alps. This regional pattern of velocities defines areas of intraplate strain. On the basis of good station coverage and of a strain rate value above a threshold, we define five provinces: Calabria, Central Apennines, both in the extensional regime, and North Adriatic, Eastern Alps and South Adriatic, under compression. We show that the orientations of the principal strain rate axes agree with the stress pattern that is inferred from local seismicity. A comparison of the geodetically determined strain rate with the strain rate associated with the seismic moment of earthquakes in the past 30 yr shows that each province may differ considerably from the others in the amount of seismic moment that is accommodated by surface strain. For example, the Umbria seismic sequence of 1997 seems to have released a seismic moment that was not exceptionally large, but concentrated over a short time interval, so that the equivalent coseismic strain rate was larger than the value observed geodetically. On average, depending on the assumptions on the seismogenic volume and time span, 70–100 per cent of the surface strain seems to be accommodated by the release of seismic moment in the upper Italian crust.
Physical Restraint Use in Intensive Care Units: Exploring the Decision-Making Process and New Proposals. A Multimethod Study

Aim: The general aim of this study was to explore the decision-making process followed by Intensive Care Unit (ICU) health professionals with respect to physical restraint (PR) administration and management, along with the factors that influence it. Method: A qual-quant multimethod design was sequenced in two stages: an initial stage following a qualitative methodology; and second, quantitative with a predominant descriptive approach. The multicenter study was undertaken at 17 ICUs belonging to 11 public hospitals in the Madrid region (Spain) across the period 2015 through 2019. The qualitative stage was performed from an interpretative phenomenological perspective. A total of eight discussion groups (DG) were held, with the participation of 23 nurses, 12 patient care nursing assistants, and seven physicians. Intentional purposive sampling was carried out. DG were tape-recorded and transcribed. A thematic analysis of the latent content was performed. In the quantitative stage, we maintained a 96-h observation period at each ICU. Variables pertaining to general descriptive elements of each ICU, institutional pain-agitation/sedation-delirium (PAD) monitoring policies and elements linked to quality of PR use were recorded. A descriptive analysis was performed, and the relationship between the variables was analyzed. The level of significance was set at p ≤ 0.05. Findings: A total of 1070 patients were observed, amounting to a median prevalence of PR use of 19.11% (min: 0%–max: 44.44%). The differences observed between ICUs could be explained by a difference in restraint conceptualization. The various actors involved jointly build up a health care culture and a conceptualization of the terms “safety-risk”, which determine decision-making about the use of restraints at each ICU. These shared meanings are the germ of beliefs, values, and rituals which, in this case, determine the greater or lesser use of restraints. There were different profiles of PR use among the units studied: preventive restraints versus “Zero” restraints. The differences corresponded to aspects such as: systematic use of tools for assessment of PAD; interpretation of patient behavior; the decision-making process, the significance attributed to patient safety and restraints; and the feelings generated by PR use. The restraint–free model requires an approach to safety from a holistic perspective, with the involvement of all team members and the family.
Chemical Modification of Glycoproteins’ Carbohydrate Moiety as a General Strategy for the Synthesis of Efficient Biocatalysts by Biomimetic Mineralization: The Case of Glucose Oxidase

Zeolitic imidazolate framework-8 (ZIF-8) is widely used as a protective coating to encapsulate proteins via biomimetic mineralization. The formation of nucleation centers and further biocomposite crystal growth is entirely governed by the pure electrostatic interactions between the protein’s surface and the positively charged Zn(II) metal ions. It was previously shown that enhancing these electrostatic interactions by a chemical modification of surface amino acid residues can lead to a rapid biocomposite crystal formation. However, a chemical modification of carbohydrate components by periodate oxidation for glycoproteins can serve as an alternative strategy. In the present study, an industrially important enzyme glucose oxidase (GOx) was selected as a model system. Periodate oxidation of GOx by 2.5 mM sodium periodate increased negative charge on the enzyme molecule, from −10.2 to −36.9 mV, as shown by zeta potential measurements and native PAGE electrophoresis. Biomineralization experiments with oxidized GOx resulted in higher specific activity, effectiveness factor, and higher thermostability of the ZIF-8 biocomposites. Periodate oxidation of carbohydrate components for glycoproteins can serve as a facile and general method for facilitating the biomimetic mineralization of other industrially relevant glycoproteins.
Effect of pupil dilation on intraocular pressure in preterm and term infants.

PURPOSE To evaluate the effect of pupil dilation on intraocular pressure in preterm and term newborns. METHODS This prospective study involved 55 eyes of 28 preterm infants and 38 eyes of 20 term infants. The infants were divided into two groups according to their gestational ages at birth as follows: preterm group, <37 weeks and term group, ≥37 weeks. Pupil dilation was attained with tropicamide 0.5% and phenylephrine 2.5%. Intraocular pressure measurements were performed with Icare PRO (Icare Finland Oy, Helsinki, Finland) before and after pupil dilation. A paired t test was used to compare the measurements before and after pupil dilation. RESULTS The mean intraocular pressure change was -1.04 ± 3.03 mmHg (6.20/-11.40 mmHg) in the preterm group and -0.39 ± 2.81 mmHg (4.60/-9.70 mmHg) in the term group. A statistically significant difference in intraocular pressure was observed only in the preterm group after pupil dilation (p=0.01). CONCLUSION An unexpected alteration in intraocular pressure in newborns may occur after pupil dilation, especially in preterm infants.
Effect of the Interfacial Layer in High- Gate Stacks on NBTI

A relative contribution of the interface and bulk dielectric defects to negative bias temperature instability (NBTI) in the metal/HfO2/SiO2 gate stacks was investigated. Interface trap generation was assessed by the direct-current current-voltage (DCIV) technique, which independently measures the interface defect density from bulk oxide charges and delineates the contribution of the interface defect generation to the overall NBTI measured by the threshold voltage shift (DeltaVTH). The metal/high-fc induced traps in the interfacial SiO2 layer were found to control the fast transient trap charging/generation processes, which affect the power-law exponents of DeltaVTH and the stress-generated interface trap density DeltaDIT stress time dependencies. Similar kinetics of the long-term DeltaVTH(t) and DeltaDIT(t) dependencies in the high-fe and SiO2 gate stacks suggests that the degradation is governed by the same mechanism of trap charging/generation in the SiO2 film. The investigation leads to a novel methodology for the time-to-failure (TTF) extrapolation, in which the measured DeltaVTH and DeltaDIT values are adjusted for the contributions from the fast transient defect charging/generation processes. It is shown that the conventional TTF analysis might greatly overestimate TTF. Post-NBTI stress recovery at zero relaxation voltage measured by the DCIV method showed that oxide charges and interface traps relax at the same rate indicating that the interface processes may dominate DeltaVTH relaxation. At positive relaxation voltages, however, the oxide charge relaxation exhibits a fast transient component. Relaxation at positive bias also shows an as yet unexplained fast component in the interface trap recovery.
Results from a wake-steering experiment at a commercial wind plant: investigating the wind speed dependence of wake-steering performance

Abstract. Wake steering is a wind farm control strategy in which upstream wind turbines are misaligned with the wind to redirect their wakes away from downstream turbines, thereby increasing the net wind plant power production and reducing fatigue loads generated by wake turbulence. In this paper, we present results from a wake-steering experiment at a commercial wind plant involving two wind turbines spaced 3.7 rotor diameters apart. During the 3-month experiment period, we estimate that wake steering reduced wake losses by 5.6 % for the wind direction sector investigated. After applying a long-term correction based on the site wind rose, the reduction in wake losses increases to 9.3 %. As a function of wind speed, we find large energy improvements near cut-in wind speed, where wake steering can prevent the downstream wind turbine from shutting down. Yet for wind speeds between 6–8 m/s, we observe little change in performance with wake steering. However, wake steering was found to improve energy production significantly for below-rated wind speeds from 8–12 m/s. By measuring the relationship between yaw misalignment and power production using a nacelle lidar, we attribute much of the improvement in wake-steering performance at higher wind speeds to a significant reduction in the power loss of the upstream turbine as wind speed increases. Additionally, we find higher wind direction variability at lower wind speeds, which contributes to poor performance in the 6–8 m/s wind speed bin because of slow yaw controller dynamics. Further, we compare the measured performance of wake steering to predictions using the FLORIS (FLOw Redirection and Induction in Steady State) wind farm control tool coupled with a wind direction variability model. Although the achieved yaw offsets at the upstream wind turbine fall short of the intended yaw offsets, we find that they are predicted well by the wind direction variability model. When incorporating the expected yaw offsets, estimates of the energy improvement from wake steering using FLORIS closely match the experimental results.
The Effect of Emotion and V2i Communication on Driver Perception of Av

As autonomous vehicles (AVs) become more prevalent on the roadways, accompanying driving technologies are being developed. V2I communication systems are one such development, allowing the dissemination of crucial information to drivers. As more AVs are introduced on the road, understanding driver perception of AVs is crucial not only for user acceptance, but non-user acceptance as well. The use of V2I systems may be helpful in bridging the gap between users and non-users by making all drivers more informed.
The Effect of Movement Control Order for Various Population Mobility Phases during COVID-19 in Malaysia

Background: COVID-19 was declared a pandemic by the World Health Organization on 11 March 2020. From the beginning of the pandemic, there was no effective pharmaceutical intervention to halt or hold up the spread of this novel disease. Therefore, most countries, including Malaysia, resorted to break the chain of transmission by restricting population mobility through the implementation of the Movement Control Order (MCO). We aim to determine the population mobility trend across the various phases of the MCO during the COVID-19 pandemic in Malaysia by studying the confirmed COVID-19 cases with the Google mobility data. Methodology: The average mobility percentage changes in Retail and Recreation, Grocery and Pharmacy, Parks, Transit Stations, and Workplaces were the components studied in relation to the various MCO phases and daily COVID-19 confirmed cases. The percentage difference was calculated by subtracting the average percentage changes for each MCO phases from the pre-MCO level. Additionally, the percentage difference was also calculated for inter-MCO phases as well. Results: The average mobility percentage changes reduced most drastically during the MCO phases across all the mobility components as compared to the other phases. The average mobility percentage changes in comparison to the pre-MCO levels across Retail and Recreation, Grocery and Pharmacy, Parks, Transit Stations, and Workplaces was −45.8%, −10.6%, −27.7%, −60%, and −34.3%, respectively. In addition, the average mobility percentage changes increased the most during CMCO as compared to MCO. Discussions: Malaysia implemented multiple measures to contain the COVID-19 pandemic since January 2020, culminating in the execution of the MCO. Though doubts on the effectiveness of the MCO were raised at the early stage of its implementation as mass movements persisted, strict enforcement and improved awareness of the impacts of COVID-19 brought significant improvement in compliance, which has been deemed the main reason behind the decrease in new COVID-19 cases since mid-April of 2020. Conclusion: Based on the downtrends of new and active COVID-19 cases, it can be concluded that the MCO has been effective, provided that compliance to the MCO is maintained. This study could serve to a certain degree to governments and policy makers as a tool to consider the relaxation of the lockdown conditions.
1993 triggered lighnting test program: Environments within 20 meters of the lighting channel and small area temporary protection concepts

Vertical electric fields, azimuthal magnetic fields, and earth step potentials at ground level have been measured at 10 and 20 meters from the base of triggered lightning flashes. For incident stroke peak currents in the range of 4.4 to 29 kA, vertical electric field change amplitudes as high as 210 kV/m were observed at 10 m, with rise times of the order of a few microseconds. Magnetic fields were found to follow Ampere`s law closely at both 10 and 20 m. Earth step potentials measured over a 0.5-m radial distance at the 10-m and 20m stations were linear with and had the same waveforms as the stroke currents. The step voltages exhibited a l/r distance dependence between the two measurement distances. A model that incorporates the presence of a thin surface layer, due to rain water saturation, of much higher conductivity than the bulk of the underlying earth is proposed to explain the observed behavior. Tests were also carried out to evaluate the effectiveness of several concepts for protecting a small exposed object, such as a piece of ordnance at the site of a transportation accident, from either a direct strike or from the indirect effects of electromagnetic fields producedmore » by a nearby lightning flash to ground. Photographs of the occurrence of significant radial filamentary arcing along the surface of the ground from the strike points were acquired. This type of arcing, with a maximum radial extent of at least 20 m, was observed on six of seven of triggered flashes and on all strokes of 15-kA peak amplitude or higher. « less
