Visible-Light-Driven Bio-Templated Magnetic Copper Oxide Composite for Heterogeneous Photo-Fenton Degradation of Tetracycline

The development of a visible-light-driven, reusable, and long-lasting catalyst for the heterogeneous photo-Fenton process is critical for practical application in the treatment of contaminated water. This study focuses on synthesizing a visible-light-driven heterogenous bio-templated magnetic copper oxide composite (Fe3O4/CuO/C) by a two-step process of bio-templating and hydrothermal processes. The prepared composite was characterized by field emission-scanning electron microscope (FE-SEM), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), electrical impedance spectroscopy (EIS), and vibrating sample magnetometer (VSM). The results reveal that the prepared composite retains the template’s (corn stalk’s) original porous morphology, and a substantial amount of CuO and Fe3O4 particles are loaded onto the surface of the template. The prepared Fe3O4/CuO/C composite was employed as a catalyst for heterogeneous photo-Fenton degradation of tetracycline (TC) irradiated by visible light. The prepared Fe3O4/CuO/C catalyst has high efficiency towards TC degradation within 60 min across a wide pH range irradiated by visible light, which is attributed to its readily available interfacial boundaries, which significantly improves the movement of photoexcited electrons across various components of the prepared composite. The influence of other parameters such as initial H2O2 concentration, initial concentration of TC, and catalyst dosages was also studied. In addition to high efficiency, the prepared catalyst’s performance was sustained after five cycles, and its recovery is aided by the use of an external magnetic field. This research paper highlights the development of a heterogeneous catalyst for the elimination of refractory organic compounds in wastewater.
Re-thinking gig economy in conventional workforce post-COVID-19: a blended approach for upholding fair balance

PurposeDespite the trend, managing and maximizing the effectiveness of blended workforce is not well-understood. The purpose of this paper is to institutionalize a blended workforce model in the post-COVID era, that is, a movement from homogenous workforce to heterogenous workforce of full-time employees working in tandem with gig talents connected via digital platforms.Design/methodology/approachThe evolution of gig economy is presented for contextualizing the development of prospective business models in the post-COVID era to establish clarity on the relationship between the employers and the blended workforce. To achieve this conceptual switch, a framework is proposed to support this type of workforce for creating a fair balance.FindingsBy drawing on the concepts of various talent management functions, propositions were made predicting that the alignment of the multilateral activities of the gig workers with permanent workforce will be leveraged in the future to address the needs of short-term specialized skill-sets and scalable operations while creating a fair balance through a flexible and agile workforce.Originality/valueFirst, the paper explores how bridging the gap between the traditional and gig workforce can impact the key antecedents of a blended workforce ensuring a fair trial. Second, on an economical level, the COOKIE framework proposed in the paper is expected to play a crucial role in creating new job opportunities, boosting employee morale while minimizing costs and increasing productivity of the organizations.
Towards Understanding Sustained Neural Activity Across Syntactic Dependencies

Abstract Sustained anterior negativities have been the focus of much neurolinguistics research concerned with the language-memory interface, but what neural computations do they actually reflect? During the comprehension of sentences with long-distance dependencies between elements (such as object wh-questions), prior event-related potential work has demonstrated sustained anterior negativities (SANs) across the dependency region. SANs have been traditionally interpreted as an index of working memory resources responsible for storing the first element (e.g., wh-phrase) until the second element (e.g., verb) is encountered and the two can be integrated. However, it is also known that humans pursue top-down approaches in processing long-distance dependencies—predicting units and structures before actually encountering them. This study tests the hypothesis that SANs are a more general neural index of syntactic prediction. Across three experiments, we evaluated SANs in traditional wh-dependency contrasts, but also in sentences in which subordinating adverbials (e.g., although) trigger a prediction for a second clause, compared to temporal adverbials (e.g., today) that do not. We find no SAN associated with subordinating adverbials, contra the syntactic prediction hypothesis. More surprisingly, we observe SANs across matrix questions but not embedded questions. Since both involved identical long-distance dependencies, these results are also inconsistent with the traditional syntactic working memory account of the SAN. We suggest that a more general hypothesis that sustained neural activity supports working memory can be maintained, however, if the sustained anterior negativity reflects working memory encoding at the non-linguistic discourse representation level, rather than at the sentence level.
Fully Printed Flexible Smart Hybrid Hydrogels

A printable hybrid hydrogel is fabricated by embedding poly(N‐isopropylacrylamide) (PNIPAm) microparticles within a water‐rich silica‐alumina(Si/Al)‐based gel matrix. The hybrid gel holds water content of up to 70 wt%, due to its unique Si/Al matrix. The hybrid hydrogel can respond to both heat and electrical stimuli, and can be directly printed layer‐by‐layer using a commercial 3‐dimensional printer, without requiring any curing. The hybrid ink is printed onto a transparent, flexible conductive electrode composed of silver nanoparticles and sustains bending angles of up to 180°, which enables patterning of various flexible devices such as smart windows and a 3D optical waveguide valve.
Quantitative Spectroscopy of Deneb

Context. Quantitative spectroscopy of luminous BA-type supergiants offers a high potential for modern astrophysics. Detailed studies allow the evolution of massive stars, galactochemical evolution, and the cosmic distance scale to be constrained observationally. Aims. A detailed and comprehensive understanding of the atmospheres of BA-type supergiants is required in order to use this potential properly. The degree to which we can rely on quantitative studies of this class of stars as a whole depends on the quality of the analyses for benchmark objects. We constrain the basic atmospheric parameters and fundamental stellar parameters, as well as chemical abundances of the prototype A-type supergiant Deneb to unprecedented accuracy by applying a sophisticated analysis methodology, which has recently been developed and tested. Methods. The analysis is based on high-S/N and high-resolution spectra in the visual and near-IR. Stellar parameters and abundances for numerous astrophysically interesting elements are derived from synthesis of the photospheric spectrum using a hybrid non-LTE technique, i.e. line-blanketed LTE model atmospheres and non-LTE line formation. Multiple metal ionisation equilibria and numerous hydrogen lines from the Balmer, Paschen, Brackett, and Pfund series are utilised simultaneously for the stellar parameter determination. The stellar wind properties are derived from H α line-profile fitting using line-blanketed hydrodynamic non-LTE models. Further constraints come from matching the photospheric spectral energy distribution from the UV to the near-IR L band. Results. The atmospheric parameters of Deneb are tightly constrained: effective temperature T eff = 8525 ± 75 K, surface gravity log g = 1.10 ± 0.05, microturbulence ξ = 8 ± 1 km s -1 , macroturbulence, and projected rotational velocity $v\,\sin\,i$ are both 20 ± 2 km s -1 . The abundance analysis gives helium enrichment by 0.10 dex relative to solar and an N/C ratio of 4.44 ± 0.84 (mass fraction), implying strong mixing with CN-processed matter. The heavier elements are consistently underabundant by ~0.20 dex compared to solar. Peculiar abundance patterns, which were suggested in previous analyses cannot be confirmed. Accounting for non-LTE effects is essential for removing systematic trends in the abundance determination, for minimising statistical 1 σ -uncertainties to $\la$10-20% and for establishing all ionisation equilibria at the same time. Conclusions. A luminosity of (1.96 ± 0.32)$\times$10 5 $L_{\odot}$, a radius of 203 ± 17 $R_\odot$, and a current mass of 19 ± 4 $M_{\odot}$ are derived. Comparison with stellar evolution predictions suggests that Deneb started as a fast-rotating late O-type star with $M^{\rm ZAMS}\simeq 23\,M_\odot$ on the main sequence and is currently evolving to the red supergiant stage.
Impact of Covid-19 pandemic on food and beverage service performance and behavioral intents: importance of sanitary measures

ABSTRACT Because of the Covid-19 pandemic, people are reluctant to dine out, which has severely impacted the hospitality industry. Based on the behavioral inhibition system theory, this research investigates the role of sanitary measures in reducing the effect of the Covid-19 threat on consumers’ approach behavior. 226 respondents were first called to share their expectations in terms of service quality and were then exposed to three different scenarios according to the three levels of sanitary measures taken by restaurants (no measure, medium-level measures, and high-level measures). The results reveal that although the perceived risk related to Covid-19 negatively impacts service quality performance, sanitary measures reduce such a negative effect from one side and directly foster the service quality performance from another side. This leads to higher satisfaction and more favorable intents of visit and recommendation. In addition, the paper emphasizes that, in terms of consumers’ expectations, hygiene is, henceforth, the most demanded dimension of the service quality. The findings of this research are especially useful for the hospitality sector to regain their customers and enhance their approach behavior in the new normal. This research is among the first studies on the topic, which was conducted during the pandemic new normal.
Meteorological Impact on Winter PM2.5 Pollution in Delhi: Present and Future Projection Under a Warming Climate

This study employs the self‐organizing map classification to track wintertime PM2.5 pollutions in Delhi under four atmospheric circulation patterns during 2013–2020. We found that the most polluted circulation pattern was characterized by a northward shift in the subtropical jet stream and a northward intrusion of the subtropical high, leading to descending anomalies from the upper troposphere to the near surface. Together, the resultant reduced passage of cyclones, lower planetary boundary layer, weakened near‐surface winds and less precipitation contributed to wintertime PM2.5 pollution in Delhi. Compared with the 1981–2010 mean levels, Coupled Model Intercomparison Project 6 models project Delhi would experience two fewer days of severe pollution‐favorable circulation pattern and seven more days of clean‐favorable circulation pattern in 2070–2099 under the shared socioeconomic pathway 5–8.5. Future decrease in the severe pollution‐favorable circulation pattern may be attributed to the warming trends in sea surface temperature over the central Pacific and North Atlantic Ocean.
Same-Admission Microvascular Maxillofacial Ballistic Trauma Reconstruction Using Virtual Surgical Planning: A Case Series and Systematic Review

Study Design: Retrospective case series; systematic review. Objective: It is unknown whether the use of virtual surgical planning (VSP) to facilitate same-admission microsurgical reconstruction of the mandible following acute maxillofacial ballistic trauma (MBT) is sufficient to achieve definitive reconstruction and functional occlusion. Methods: A single-center retrospective analysis was conducted for patients who underwent microsurgical reconstruction of the mandible using VSP after acute MBT. The PubMed/MEDLINE, Embase, ScienceDirect, and Scopus databases were systematically reviewed using blinded screening. Studies were evaluated via thematic analysis. Results: Five patients were treated by same-admission and microsurgical reconstruction of the mandible using VSP. We observed an average of 16.4 ± 9.1 days between initial presentation and reconstruction, an average length of stay of 51.6 ± 17.9 days, 6.2 ± 2.8 operations, and 1.6 ± 0.9 free flaps per patient. Four types and 8 total flaps were employed, most commonly the anterior lateral thigh flap (37.5%). Care yielded complete flap survival. Each patient experienced at least 1 minor complication. All patients achieved centric occlusion, oral nutrition, and an approximation of their baseline facial aesthetic. Follow up was 191.0 ± 183.9 weeks. Systematic review produced 8 articles that adhered to inclusion criteria. Consensus themes in the literature were found for clinical goal and function of VSP when practicing MBT reconstruction, yet disagreement was found surrounding optimal treatment timeline. Conclusions: Same-admission microsurgical reconstruction after MBT is safe and effective to re-establish mandibular form and function. VSP did not delay reconstruction, given the need for preparation prior to definitive reconstruction.
Prevalence of Dermoscopic signs in Egyptian psoriatic patients with different skin phototypes and different plaque locations

Dermoscopy is a non-invasive technique that has been recently utilized for the diagnosis and management of many skin disorders. It also provides information about inflammatory skin diseases e.g. psoriasis, lupus, and so on. Psoriasis is a papulosquamous disease with variable distribution, morphology, severity and course, affecting about 1.5% of the population. In this study 218 cases of classic psoriasis were examined clinically and by dermoscopy. Dermoscopic signs found in psoriasis were bushy capillaries (dotted vessels), erythema and scales. Bushy capillaries presented in 99.5% of all cases, erythema presented also in 99.5% and scales presented in 92.7%. We found that, type and site of psoriasis have little or no effect on erythema but have significant effect on scales especially flexural psoriasis due to humidity, and skin phototype has no or little effect on dermoscopic finding in psoriasis as there is no significant effect of skin color on visibility of the bushy capillaries, erythema or scales. In conclusion, the well-known dermoscopic criteria of psoriasis, namely bushy capillaries, erythema and scaling are seen in dark skin as well as in those in light skin, in lesions of different locations, with the frequency of white scales varying among different body sites.
Lateral Hypothalamus Corticotropin-releasing Hormone Receptor-1 Inhibition and Modulating Stress-induced Anxiety Behavior

Introduction: Stress is a reaction to unwanted events disturbing body homeostasis and its pathways and target areas. Stress affects the brain through the lateral hypothalamic area (LHA), the orexinergic system that mediates the effect of corticotropin-releasing hormone (CRH) through CRH Receptor Type 1 (CRHr1). Therefore, this study explores the outcome of stress exposure on anxiety development and the involvement of the LHA through LHA-CRHr1. Methods: Male Wistar rats (220–250 g) implanted with a cannula on either side of the LHA received acute or chronic stress. Subsequently, exploratory behavior was examined using the Open Field (OF), and anxiety was tested by Elevated Plus Maze (EPM). Before sacrifice, the cerebrospinal fluid (CSF) and the blood were sampled. Nissl stain was performed on fixed brain tissues. Results: Acute stress reduced exploration in of and increased anxiety in EPM. LHA-CRHr1 inhibition reversed the variables to increase the exploration and decrease anxiety. In contrast, chronic stress did not show any effect on anxiety-related behaviors. Chronic stress decreased the cell population in the LHA, which was prevented by the CRHr1 inhibition. However, the CRHr1 inhibition could not reverse the chronic stress-induced increase in the CSF orexin level. Furthermore, plasma corticosterone levels increased through acute or chronic stress, impeded by the inhibition of CRHr1. Conclusion: Our results recognize LHA-CRHr1 as a capable candidate that modulates acute stress-induced anxiety development and chronic stress-induced changes in the cellular population of the region. Highlights Acute stress, increased immobility of the rat in open field and elevated plus maze. Chronic stress, increased orexin production while decreasing neuronal survival. The anxiety and immobility were not developed in presence of CRHr1. CRHr1 blocking reversed the chronic stress changes in corticosterone and orexin. Plain Language Summary Lateral Hypothalamus (LH) is a region involved in sleep and appetite regulation and recently known to play role in stress pathophysiology. The stress mediating function of the LH is performed through Corticotropin Releasing Hormone Receptor type-1 (CRHr1). This study explored the role of LH- CRHr1 in anxiety development and orexin production. Acute and chronic stress affected the behavior and molecular changes, differently. The acute stress increased the anxiety condition, while the chronic stress could only change the molecular criteria. Although we assumed that the inability of the chronic stress to develop anxiety may be attributable to habituation, the chronic stress could increase the plasma corticosterone and orexin level. All of the stress mal-changes in behavior and molecular level prevented by antagonising CRHr1 in the LH, indicating a gating function of LH-CRHr1 for stress development.
Buffaloes (Bubalus bubalis) mycotic eye infection: reported herd cases in Thi-Qar province, Iraq

Buffaloes are one of the important farm animals in the south of Iraq and play an essential economical role mainly acting as dairy, meat, and draft animals. This study intended to diagnose buffalo mycotic eye infections in Thi-Qar province/Iraq. Some 250 buffaloes in the herd of 3,700 animals suffered from eye infections from December 2017 to November 2018. Eye swabs were collected from each infected eye of the affected buffaloes of both sexes before treatment. The animals were in different age groups. All samples were transferred to the laboratory in transfer media, and cultured on Sabouraud dextrose (SDA) agar with and without 0.05 g/mL and 0.4 g/mL chloramphenicol and cycloheximide, respectively. Later, the agars were incubated at 25o C and 37o C. The total percentage of eye infection was (6.75%), constituting (49.2%) mycotic infections. The predominant clinical manifestations that appeared on the infected buffaloes were eye inflammation represented by congestion, lacrimation, the opacity of cornea and edema, and reduced productivity of the infected animals. Different fungal isolates were identified from the samples including Aspergillus fumigates, Aspergillus flavus, Aspergillus niger, Penicillium spp. , Alternaria spp. , Fusarium spp. , Candida spp. , Cladosporium spp. , Rhodotorula spp. , Mucor spp. and Rhizopus spp. Calves buffaloes below one-year-old were more prone to mycotic infection than one-year-old or more. Additionally, male buffaloes were more susceptible to infection than females. In conclusion, this study isolated various types of fungus from the inflamed eyes of buffaloes. Fungal eye infection and the potential risk factors for fungal keratitis in buffaloes were also investigated. The study also approved the rapid diagnosis of fungi by direct microscopic detection and culture. The author recommends future studies including large numbers of the buffalo herd in Iraq to determine the epidemiology of this condition in the country.
Effects of Pacifiers on Peripheral Capillary Oxygen Saturation during Wake Time

We studied the variations in peripheral capillary oxygen saturation (SpO2) during wake time in relation to pacifier use and to the following different positions: supine at 0°, supine at 30° (in babies under one year) vs. sitting (in babies between 1 and 3 years of age). We observed 54 patients under the age of three years, weighing over 1.800 g. Peripheral oxygen saturation was recorded for at least 40 min per patient in the following positions: 20 min lying supine at 0° (10 min with a pacifier and 10 min without); 20 min lying supine at 30° inclination or in a sitting position if the baby was older than one year (10 min with a pacifier and 10 min without). Pacifier use improved the peripheral oxygen saturation both in the 0° supine position, and at 30° in a sitting position. No significant differences were observed in the SpO2 levels comparing the different positions. In conclusion a pacifier thus seems to have a positive effect on respiration.
