Nurse anesthetists' perceptions and experiences of managing emergence delirium: A qualitative study.

This study employs a descriptive phenomenological approach to investigate the challenges anesthesia nurses face in managing emergence delirium (ED), a common and complex postoperative complication in the post-anesthesia care unit. The role of nurses in managing ED is critical, yet research on their understanding and management strategies for ED is lacking. To investigate anesthetic nurses' cognition and management experiences of ED in hopes of developing a standardized management protocol. This study employed a descriptive phenomenological approach from qualitative research methodologies. Purposeful sampling was utilized to select 12 anesthetic nurses from a tertiary hospital in Shanghai as research subjects. Semi-structured interviews were conducted, and the data were organized and analyzed using Colaizzi's seven-step analysis method, from which the final themes were extracted. After analyzing the interview content, four main themes and eight subthemes were distilled: Inefficient cognition hinders the identification of ED (conceptual ambiguity, empirical identification), managing diversity and challenges (patient-centered safe care, low level of medical-nursing collaboration), work responsibilities and pressure coexist (heavy work responsibilities, occupational risks and stress), demand for high-quality management (expecting the construction of predictive assessment tools and prevention strategies, and pursuing standardized management processes to enhance management effectiveness). Nursing managers should prioritize the needs and suggestions of nurses in order to enhance their nursing capabilities and provide guidance for standardized management processes.

Nitrogen plasma treated cotton fabrics coated with SiO2 followed by RGO deposition for water purification process

Experimental investigations have been carried out to modify the surface properties of Cotton fabrics using low temperature DC glow discharge nitrogen plasma. Plasma treatment is an eco-friendly, dry and clean process over wet chemical methods and does not suffer from any environmental and health concerns [1]. The important plasma parameters such as power and working pressure are kept constant with various treatment times (5, 15, 30, and 60 mins). The plasma-treated cotton fabrics are optimized by XRD, FTIR, and SEM. A comparative study has been done for the untreated and different treated fibers. Pure SiO2 is coated on untreated and nitrogen plasma treated cotton fabrics by sputtering method. The samples are coated for different sputtering times (10 and 30 min). Finally, Reduced Graphene Oxide (RGO) is coated on plasma treated SiO2 deposited fabrics. RGO is prepared by modified hummers methods [2]. Our results provide a way to develop a filter for water purification.

Thermal Characterization and Preclinical Feasibility Verification of an Accessible, Carbon Dioxide-Based Cryotherapy System.

To investigate the potential of an affordable cryotherapy device for the accessible treatment of breast cancer, the performance of a novel carbon dioxide-based device was evaluated through both benchtop testing and an in vivo canine model. This novel device was quantitatively compared to a commercial device that utilizes argon gas as the cryogen. The thermal behavior of each device was characterized through calorimetry and by measuring the temperature profiles of iceballs generated in tissue phantoms. A 45 min treatment in a tissue phantom from the carbon dioxide device produced a 1.67 ± 0.06 cm diameter lethal isotherm that was equivalent to a 7 min treatment from the commercial argon-based device, which produced a 1.53 ± 0.15 cm diameter lethal isotherm. An in vivo treatment was performed with the carbon dioxide-based device in one spontaneously occurring canine mammary mass with two standard 10 min freezes. Following cryotherapy, this mass was surgically resected and analyzed for necrosis margins via histopathology. The histopathology margin of necrosis from the in vivo treatment with the carbon dioxide device at 14 days post-cryoablation was 1.57 cm. While carbon dioxide gas has historically been considered an impractical cryogen due to its low working pressure and high boiling point, this study shows that carbon dioxide-based cryotherapy may be equivalent to conventional argon-based cryotherapy in size of the ablation zone in a standard treatment time. The feasibility of the carbon dioxide device demonstrated in this study is an important step towards bringing accessible breast cancer treatment to women in low-resource settings.

A highly-sensitive wearable capacitance pressure sensor based on calcium copper titanate/polydimethysiloxane/graphene oxide and polydimethysiloxane/silver nanowires sanwich strustures combination for human body monitoring

In recent years, flexible pressure sensors, with their high sensitivity, low detection limit, wide working pressure range and fast response speed, have been playing an important role in the development of wearable artificial devices, human-computer interaction and healthcare systems, and have attracted wide attention. However, the pressure sensors face challenges related to the weak tightness of bipolar materials, low charge density, and limitation in dielectric layers. In this paper, we present a novel configuration of flexible capacitive pressure sensors, utilizing a polydimethysiloxane (PDMS) thin film covered by silver nanowires (PDMS/SN, PSN) as the electrode materials and a porous material composed of calcium copper titanate (@CCTO), PDMS and graphene oxide (GO)(@CCTO/PDMS/GO, @CPG) as the positive electrode material. The sacrificial material, sugar, is employed to create dense internal pores within the substrate material, @CPG, leading to the formation of a profoundly porous substrate. The integration of the flexible capacitive pressure sensor using @CPG/PSN results in enhanced output performance. The modified sensors achieves a sensitivity of 0.22 kPa−1, which is 7 times higher than that of a pure PDMS dielectric layer sensor. Moreover, the sensors has a response time of 87 ms, a low detection pressure of 5 Pa with an extensive detection range from 0 to 150 kPa, and are capable of enduring 7200 cycles without sustaining damage. To validate the practical performance of the @CPG/PSN sensor, various human body activities are detected, including swallowing, coughing, neck bending, wrist bending, elbow bending, finger flexing, and holding objects like cups using a digitally designed glove capable of accommodating different materials. The pressure sensor based on @CPG/PSN demonstrates significant promise in detecting both low and high pressures, thus expanding the potential applications of capacitive pressure sensors.

Sleep Disorder and its Treatment: From Nature to Laboratory

Sleep is the natural cellular repair mechanism to improve and restore central neural mechanism, memory, hormonal imbalance, and finally, cell rejuvenation. Sleep disorder is characterized by insomnia, circadian rhythm disorder (CRD), sleep apnea, narcolepsy, parasomnia, and restless leg syndrome (RLS) or periodic limb movement disorder (PLMD). Both oversleeping and less sleeping are associated with sleep disorders (SD). Anxiety, schizophrenia, weight loss/gain, hypothyroidism, and oxidative stress are the most common outcomes of SD. There is also a genetic explanation behind circadian rhythmicity, circadian disorder, narcolepsy-cataplexy syndrome, fatal familial insomnia, and somnambulism. Excessive work pressure, stress, and consumption of caffeine and alcohol collectively push a person toward sleep deprivation. Anxiety, schizophrenia, weight loss/gain, hypothyroidism, and oxidative stress are the most common outcomes of SD. Adenosine, melatonin, dopamine, serotonin, gamma amino butyric acid (GABA), orexin, and histamine regulate SDs by various pathways. Among natural sources, Centella asiatica, Bacopa monnieri, Acorus calamus, Withania somnifera, Nardostachys jatamansi, Poria cocos is, Valeriana officinalis, Matricaria chamomilla, Lavandula angustifolia, Nelumbo nucifera, Melissa officinalis, Convolvulus pluricaulis, Camellia sinensis, Ziziphus jujube, Datura stramonium, Zhizhipus jujube, Passiflora incarnata, and Moringa oleifera showed remarkable effects on different forms of SDs through GABAA, serotonin, and melatonin receptors. Pramipexole, ropinirole, rotigotine, clonazepam, lorazepam, estazolam, zolpidem, lemborexant, daridorexant, and suvorexant showed its activity in the treatment of SDs as a dopamine agonist, inhibitor of GABAA receptor, dual orexin receptor antagonist, respectively. This article focused on the types of SDs, the effects of SDs on mental health, receptors involved in the sleep cycle, and the impact of natural molecules and synthetic molecules in the management of SDs.

Pressure, compromise and overwork: How Australian regional journalists gain job satisfaction through community service

In a time of enormous change in the Australian news media industry – with outlet closures, redesign of company business models, rationalization of staff and shifts in medium uptake – this article explores journalists’ exposure to and perceptions of work pressures in their jobs. It explores the relationship of these experiences with the journalists’ job satisfaction. The study reports that journalists find the industry difficult and demanding, with time pressures, ethical compromise and overwork being their main concerns. However, the study also found that journalists still derive satisfaction from a profession they perceive as meaningful through informing their communities about matters that affect their decision making and how they live. This passion for community service alongside the notion of holding authority to account result in a sense of overarching job satisfaction. This article presents part of a study that investigated the experience of journalists in remote and regional media organizations in Queensland and New South Wales through survey and interviews.

You have to work more than men to succeed! Gender differences in workaholism among Italian academics

Over the last decades, Italian university reforms have put increased pressure on academics and researchers towards greater productivity and accountability. These changes have generated an ‘overtime culture', which is one of the main determinants of workaholism, over-commitment, and presenteeism among academics. The consequences of such changes are not gender-neutral: women – more often disadvantaged in academic careers than men – might be more affected by increased work pressure and more likely to work excessively to avoid career penalties. By using an original web-survey of about 1300 academics from four Italian universities, this article investigates gender differences in workaholic behaviours (i.e., working at night, on Sundays, etc.), and their link with the way researchers perceive the recruitment processes and gender disparities. The authors found that women are more workaholic than men, and this is explained by perceptions of gender equality in their working environment.

Gallium nitride deposition via magnetron sputtering: Linking plasma-surface interactions and thin film crystalline features

Ga-atoms dynamic in an Ar/N2 magnetron sputtering discharge for GaN deposition is explored employing plasma diagnostic techniques such as optical emission spectroscopy and microwave interferometry. Through the assessment of gas temperature, electron temperature and density measured from the abovementioned diagnostics, we estimated both the flux and average energy of Ga-atoms impinging on the substrate. Emphasizing the working pressure as a pivotal factor, this study uncovers a correlation between the Ga-atoms flux, their average energy, and the growth rate and crystallinity of the GaN films extracted from ex-situ characterizations. Notably, the pressure value (6.6 Pa) at which both the growth rate and crystalline fraction are the greatest is also the condition at which both the flux and energy of Ga-atoms impinging on the target are maximal. The findings pave the way for improving the understanding and control of the complex interplay between plasma conditions and resulting film properties in the sputtering process.

Teachers’ Occupational Stress and Coping Mechanisms

Teachers often experience high levels of stress in their work, but they are equipped with effective coping mechanisms to navigate through it. This study aimed to explore the relationship between teachers' occupational stress and coping mechanisms in public elementary settings. It sought to assess occupational stress based on working, living, and subjectrelated conditions while also evaluating teachers' emotion-focused and problem-focused coping mechanisms. Additionally, it aimed to establish significant relationships between occupational stress and these coping mechanisms. A descriptive correlational involving 145 public elementary teachers in Opol-West District, Misamis Oriental, utilized universal sampling. The study utilized an adapted and modified instrument from Cayao and Arenga (2021) and achieved a reliable Cronbach alpha of 0.855 to validate the survey questionnaire. Statistical tools, including mean, standard deviation, and Pearson correlation coefficients, were employed to analyze the data. Results showed that teachers feel some stress in their living conditions, but report challenges bring extreme stress. They also have moderate stress from subject-related conditions. It was concluded that teachers wanting to grow professionally can occasionally add stress to their overall work pressure. It was recommended that, implement strategies for teachers by coming up with better ways to submit reports.

Theoretical helium liquefaction rate based on the temperature-distributed refrigeration method in regenerative refrigerators

Helium liquefaction is important for applications of cryogenic engineering, helium recovery and purification, and so on. Regenerative refrigerators are generally applied for small-scale applications because of their relatively high efficiency, competitive compactness, etc. However, the liquefaction efficiency (the ratio of the input power of the ideal liquefaction cycle to that of the practical cycle) of helium is low. In this paper, a novel method called temperature-distributed refrigeration to improve the performance of helium liquefiers by utilizing distributed refrigeration power is proposed. The theoretical liquefaction efficiency by applying this method in the regenerative cycle is analyzed. The analysis assumes that there is no radial thermal resistance during the transmission of refrigeration power. The working pressure of helium in the refrigerator is in a wide reduced pressure range of 4.0–61.7, with the liquefied helium maintained at 0.1 MPa. The results indicate that the theoretical maximum liquefaction rate reaches 50.5 L/d (1.5 W at 4.2 K). This liquefaction rate is 2–3 times that of liquefying with only the cold ends. Meanwhile, the liquefaction efficiency increases with the working pressure, reaching a theoretical maximum of 44.5 % at a reduced pressure of 61.7. It is the highest possible efficiency for a two-stage regenerative refrigerator. This method should provide a reference for the optimization of small-scale helium liquefaction systems.

The Influence of Nitrogen Partial Pressure on the Microstructure and Mechanical Properties of HfNbTaTiVZr High-Entropy Nitride Coating Deposited via Direct Current Cathodic Vacuum Arc Deposition

In recent years, high-entropy alloys have attracted increasing scientific interest. Due to their promising combination of properties, such as high hardness and high temperature stability, they are attractive for use as tool coatings for machining applications, to give but one example. Previous studies often focused on layer deposition using magnetron sputtering. Comparatively little research has been carried out to date on coating deposition using direct current cathodic vacuum arc deposition (CAE), with higher achievable rates and almost completely ionized plasmas. The aim of this work is to investigate (HfNbTaTiZr)N-coatings produced by CAE. The nitrogen content was varied and the effects on the coating properties were investigated. Changing the N2/(N2 + Ar) ratio between 0.1 and 1.0 and varying the working pressure in the chamber from 2 Pa to 5 Pa resulted in variations of the nitrogen content of the coatings, ranging from 30 at% to 50 at%. Although different microstructures of the coatings were obtained, there was only a minor influence on the hardness and Young’s modulus.

Using a coupled optical and electrical monitoring method to follow the R-HiPIMS TiO2 deposition process drifts

In this work, coupled optical and electrical discharge measurements have been implemented to investigate the plasma state of a reactive HiPIMS TiO2 deposition process running at a fixed duty cycle of 2% and at a repetition rate of 1 kHz. Investigations focus on both the effect of the erosion target and substrate-holder temperature in an Ar/O2 gas mixture at fixed working pressure. First, as the racetrack shape evolves with the use of the target, the deposition rate is modified, in the same way as the emission intensity measured. Second, with the heater set at 400 °C in pure Ar, the coating appears thinner, and the optical emission spectroscopy measurement reveals the presence of oxygen atoms. Thus, the results from the coupled optical and electrical measurements are sensitive enough to track potential drift of the process.

The relationship between servant leadership and cyberloafing: an investigation of meaningful work versus citizenship pressure

ABSTRACT Cyberloafing is a form of counterproductive work behaviour (CWB), that is increasingly prominent yet easily concealed. This organizational phenomenon poses numerous detrimental effects on organizations, underscoring the importance of understanding the factors that can mitigate employee cyberloafing. Drawing on social exchange theory (SET) and social information processing theory (SIP), this study proposes an integrated model that explores the double-edged sword effect of servant leadership on cyberloafing. We hypothesize that servant leadership may increase meaningful work or citizenship pressure, thereby discouraging or facilitating cyberloafing. Meanwhile, we investigate the moderating effect of regulatory focus (promotion focus and prevention focus). Data were collected from 375 Chinese employees in three waves, with a two-week interval between each wave. The results showed that servant leadership enhanced meaningful work, resulting in a disincentive to cyberloafing. Conversely, servant leadership intensified citizenship pressure, leading to an increase in cyberloafing. The negative indirect effect of servant leadership on cyberloafing via meaningful work was moderated by promotion focus. Specifically, this indirect effect was more pronounced when the promotion focus was higher. Our research offers crucial insights for preventing employee cyberloafing in organizations.

Bridging the innovation gap: Why organizational climate matters for leveraging innovation from supply networks

AbstractRecent studies have provided empirical evidence that innovation performance is related to the way a firm is embedded in its supply network, specifically the centrality of its network position, but it remains unclear why some firms can use inputs from suppliers better than others, despite having comparable structural characteristics in their supply networks. Drawing on theories of social networks and organizational climate, this study examines the role of buying firms' organizational climate for innovation. It uses several structured and unstructured datasets for S&P 500 firms and applies count regression models to test hypotheses. Supply network data from FactSet were analyzed to determine the degree centrality of a buying firm. Computer‐aided content analysis was used to capture the organizational climate of buying firms based on online employee reviews collected from Glassdoor. The results suggest a positive relationship between the degree centrality and the innovation performance of buying firms. Moreover, certain facets of the organizational climate related to learning, including rewards and career progress, as well as work pressure management, affect the link between the degree centrality of a buying firm and its innovation performance. In conclusion, this study enhances the understanding of the connection between supply networks and innovation. It highlights the crucial role of a firm‐level factor, specifically the influential facets of organizational climate for learning, in determining innovation performance.

Experimental and numerical investigations on soil–water dynamics in Moistube irrigation under dynamically regulated working pressure heads: scenario simulations under maize cultivation

Moistube irrigation (MTI) accurately delivers moisture to root zone through subsurface nanotube irrigators. How to dynamically adjust the working pressure head (WPH) considering crop evapotranspiration remains unstudied. Here, the Moistube discharge characteristics, wetting front (WF) morphology, and soil water content (SWC) distribution under adjusted WPH (0 → 1, 0 → 2, 1 → 2, 1 → 0, 2 → 0 and 2 → 1 m) were experimentally investigated. HYDRUS 2D model was employed to reproduce the soil water dynamics and validated against the experimental data. Maize growth scenarios under regulated WPH for three representative regions (Nanjing, Hami, and Siping in China) with typical hydrological years were performed. The relatively long-term Moistube discharge, SWC, and deep percolation were analyzed. Results demonstrated that flexible WPH adjustment regulated Moistube discharge, the advance velocity of WF, and SWC within the wetting patterns. With increased (or decreased) WPH, the Moistube discharge rate precipitously raised (or descended) to values positively correlated with WPHs. WPHs of 0, 1, and 2 m corresponded to discharge rates of 0.63–0.76, 2.15–3.34, and 5.53–6.41 cm2 h−1, respectively. WF also noticeably accelerated (or decelerated) as WPH, meanwhile SWC within the wetting pattern increased (or decreased). Upon WPH increase, the elevated SWC intensified the deviation (δ) of wetting body centroid from Moistube. HYDRUS 2D model accurately reproduced the Moistube discharge rate and WF advance (R2 ≥ 0.90, NSE ≥ 0.70, RSR close to 0), corroborating the feasibility of treating Moistube as a heavy clay. Surprisingly, the Moistube discharge rate obeyed exponential decreasing trend over time after WPH increased but abnormally displayed restrained trends followed by rebounding after WPH decreased. SWC and the deviation of wetting body centroid from Moistube exhibited discrepancies in absolute values but consistencies in trends between the observed and simulated data. Scenario analyses of maize cultivation revealed that regulating WPH accurately replenished crop evapotranspiration and maintained appropriate SWC environments. Regulated WPH in MTI was efficacious in reducing deep percolation and suitable for arid regions. These results could contribute to intelligent MTI by automatically maintaining a balance between Moistube discharge and crop water requirements.
