Fatigue in hospital nurses can endanger the safety of both the nurse and the patient. One of the factors that can cause fatigue in hospital nurses is the physical environmental, such as lighting, noise, and work climate. The purpose of this study is to analyze the physical work environment factors (lighting, noise, and work climate) associated with work fatigue in hospital nurses. This is a systematic literature review on studies that discuss physical work environment factors related to work fatigue in hospital nurses published in international journals and local journals that can be accessed through the UI Library, especially those that are Full Open Access. Fourteen articles that discussed the relationship between physical environmental factors and work fatigue in hospital nurses were identified, consisting of 11 articles on the effect of lighting on work fatigue in hospital nurses. 6 articles discussed how noise influenced work fatigue in hospital nurses, and 3 articles discussed the effect of hot work climate on work fatigue in hospital nurses. Based on the review, lighting, noise, and work climate significantly link to work fatigue in hospital nurses. Keywords: hospital, lighting, noise, nurses, work climate, work fatigue

Published: May 2023

L’essor de la technologie dans les organisations rend désormais possible la collecte et l’accès à des quantités massives d’informations de diverses natures et provenant de différentes sources (c.-à-d. des mégadonnées ou « Big Data »), permettant ainsi de mesurer et de comprendre sous un nouvel angle la complexité du vécu des employés en milieu de travail. Le premier objectif de cet article est de présenter sommairement la façon dont l’accessibilité croissante des mégadonnées a le potentiel de révolutionner la recherche et la pratique dans le monde du travail. Par ailleurs, le second objectif est d’exposer certaines limites et certaines vigilances à avoir en tant que chercheur, à l’égard des enjeux éthiques liés à l’accès, à l’utilisation, et à l’interprétation de ces mégadonnées. Quelques pistes de réflexion concernant l’élaboration de devis, le consentement lié à la participation et la multiplicité des acteurs impliqués dans ce nouveau type de recherche organisationnelle sont proposées.
Excursion en terra semicognita : la « francotropie » des Amériques et la vitalité des communautés franco-minoritaires au Canada
Authors: Rivard Étienne 
Published: May 2023

L’article s’inscrit dans le prolongement des études sur l’immigration touchant les communautés francophones en situation minoritaire (CFSM). Il repose sur une démarche exploratoire centrée sur la notion de francotropie, laquelle fait référence aux populations non francophones à l’origine, mais qui seraient davantage prédisposées à faire l’apprentissage du français. L’objectif est double : d’une part, on vise à scruter en quoi la notion de francotropie peut contribuer à la vitalité des CFSM; d’autre part, on cherche à évaluer les enjeux et les défis spécifiques associés à l’immigration des francotropes dans ces communautés. L’analyse est basée sur des données statistiques et censitaires relatives à une population francotrope et immigrante spécifique, celle venant d’Amérique latine, et cela, à l’échelle du pays. Cette analyse met en lumière une disparité évidente entre le Québec et les CFSM.

The study aimed to evaluate the composition and diversity of algae in the JP Lake of Jahangirnagar University campus. The research was carried out between the period of December 2021 to November 2022. A total of 72 water samples were used to carry out the investigation. Shannon and Simpson diversity indexes were used to determine the level of diversity. 234 phytoplankton species under 98 genera were found belonging to 8 classes (Cyanophyceae, Chlorophyceae, Bacillariophyceae, Synurophyceae, Euglenophyceae, Cryptophyceae, Dinophyceae, and Xanthophyceae). According to the generic percentage composition, Chlorophyceae comprised 46%, followed by Bacillariophyceae (20%) and Cyanophyceae (18%). At the species level, Euglenophyceae were found to dominate (34%) the studied sites that were followed by Chlorophyceae (31%) and Cyanophyceae (18%). The total density of phytoplankton was 387.34×105 ind/l. The highest phytoplankton density was found in April, and the lowest one was in November. Cell dispersion was below average in May for Cyanophyceae, Bacillariophyceae, Cryptophyceae, and Synurophyceae. Oscillatoria, Monoraphidium, Actinastrum, Cosmarium, Trachelomonas, and Euglena dominated the surveyed region. The Shannon Diversity Index showed a value of 1.51, while Simpson's Diversity Index showed a value of 0.28. The overall variation (80.73%) among the classes was represented by PCA cells. According to the Shannon and Simpson Diversity Indexes, the diversity was low.

Published: May 2023

The changing of the diversity of lactic acid bacteria (LAB) from one locality and another is one of the main reasons of the organoleptic and physicochemical differences encountered in the same class of cheese. The objective of this work was to evaluate the influence of LAB isolated from cow's milk produced locally in Cameroon on the organoleptic and physicochemical quality of soft cheese with bloomy rind. To this effect, 05 LAB (IS1, IS2, IS3, IS4 and IS5) were isolated to fresh milk and selected after macroscopic, microscopic and biochemical characterizations. After tests of acidification, fermentation type, compatibility between LAB and LAB concentration on milk coagulation, the combined IS1-IS4-IS5 and IS2-IS3-IS5 were retained to produce 02 soft cheeses with bloomy rind namely respectively FROCAM 145 and FROCAM 235. When used at concentrations of 3×107 CFU/mL, these combined LAB coagulate fresh renneted milk after 3 hours at 26°C. During the production of FROCAM 145, the combined IS1-IS4-IS5 resulted in a firm, moist curd and a pH reduction of 14 and 15% respectively after the milk maturation and ripening of FROCAM 145. This cheese recorded 100% mould recovery, with protein, lipid and calcium content of 6.7, 62.2 and 0.1% respectively. On the other hand, during the production of FROCAM 235, the combined IS2-IS3-IS5 resulted in a dry and crumbly curd. The pH recorded with this combined LAB after maturation of the milk and ripening of FROCAM 235 is 12 and 17% respectively. The FROCAM 235 recorded a low mould recovery estimated at 20% and a protein, lipid and calcium content of 7.8, 65.1 and 0.3% respectively. From a microbiological point of view, FROCAM 145 and FROCAM 235 did not record any contamination by Listeria monocytogenes, Salmonella and Staphylococci. The sensory analysis shows that FROCAM 145 was more appreciated than FROCAM 235 with scores of 0.74 and 0.24 respectively. In view of these results, the IS1-IS4-IS5 combinations isolated from Cameroonian milks present a certain technological interest in the transformation of milk into cheese.

Published: May 2023

The aim of this study was to evaluate the impact of cooking conditions on the proximate composition and textural properties (cohesiveness and chewiness) of chicken breast meat. Eight packs of industrial skinless chicken breast meat were cooked by air frying (AF), baking (BK), deep fat frying (DF) and grilling (GR) at 170, 180 and 190oC for 0, 4, 8, 12 and 16 min. The chicken breast packs were frozen and sliced into dimensions, thawed, cooked and analysed by a two way analysis of variance. The results revealed that cooking methods significantly (p < 0.05) decreased moisture and protein contents from 75.14 to 58.25% and 89.17 to 82.98%, but increased fat content from 4.26 to 7.78%, ash content from 1.95 to 2.39%, carbohydrate content from 4.63 to 6.95%, cohesiveness content from 0.40 to 0.52 and chewiness value from 3.63 to 6.05 kg. An increases in cooking temperatures and times decreased moisture content from 60.58 to % 56.34% and 75.14 to 47.40% and protein content from 83.77 to 82.11% and 89.17 to 79.45%. Similarly, increases in cooking temperatures and times significantly (p < 0.05) increased fat content from 7.00 to 8.44% and 4.26 to 10.12%, ash content from 2.15% to 2.59% and 1.95 to 2.67%. This study showed that increases in cooking temperatures decreased non-significantly (p > 0.05) carbohydrate content from 7.02 to 6.92%, but increases in cooking times increased carbohydrate content from 4.63 to 7.76%. An increases in cooking temperatures and times increased cohesiveness content from 0.50 to 0.54 and 0.40 to 0.63, chewiness value from 5.50 to 6.77 kg and 3.63 to 8.54 kg, respectively. There were no significant differences (p > 0.05) in chewiness values of samples cooked by AF and GR methods. The best cooking method/ temperature / time for low nutrient losses was BK, 170oC and 4 min.

Published: May 2023

AbstractDrawing inspiration from the jumping motions of living creatures in nature, jumping robots have emerged as a promising research field over the past few decades due to great application potential in interstellar exploration, military reconnaissance, and life rescue missions. Early reviews mainly focused on jumping robots made of lightweight and rigid materials with mechanical components, concentrating on jumping control and stability. Herein, attention is paid to the jumping mechanisms of soft actuators assembled from various soft smarting materials and powered by different stimulus sources. The challenges and prospects of soft jumping actuators are also discussed. It is hoped that this review will contribute to the further development of soft jumping actuators and broaden their practical applications.

Published: May 2023

AbstractAntibacterial elements and non‐contact heating abilities have been proven effective for antibacterial and antibiofilm activities, but it remains a challenge to integrate both within one material. Herein, assisted by the high‐entropy effect, FeNiTiCrMnCux high‐entropy alloy nanoparticles (HEA‐NPs) with excellent photothermal heating properties for boosting antibacterial and antibiofilm performances are synthesized. Benefitting from the synergetic effect of copper ions released and thermal damage by the HEA‐NPs, more reactive oxygen species (ROS) are generated, leading to the rupture of the cell membranes and the eradication of the biofilms. As a result, the antibiofilm efficiency (400 µg mL−1) of the mostly optimized FeNiTiCrMnCu1.0 HEA‐NPs in the marine nutrient medium, which is the worst‐case scenario for the antimicrobial material, can be improved from 81% to 97.4% under 30 min solar irradiation (1 sun). The present study demonstrates a new strategy for effectively treating marine microorganisms that cause biofouling and microbial corrosion using HEA‐NPs with photothermal heating characteristics as an antibacterial auxiliary.

AbstractAchieving high NO conversion and N2 selectivity in selective catalytic reduction of NO by CO (CO‐SCR) in a wide operating temperature window, particularly in the presence of high O2 concentration, remains a big challenge. Herein, guided by density functional theory (DFT) calculations, a catalyst is rationally developed with dual active centers consisting of both Co single‐atoms (SAs) and CoOx nanoclusters (NCs) co‐anchored on Ce0.75Zr0.25O2 support (CZO), which show above 99.7% NO conversion and 100% N2 selectivity at 250–400 °C under 5 vol% O2. DFT calculation and experimental results confirm a strong interaction among Co SAs, CoOx NCs, and CZO support. Co SAs enhance CO adsorption and accompany the oxygen vacancies (OVs) formation in CZO, while the CoOx NCs promote both NO conversion to nitrate intermediate and the breakage of the NO bond at OVs, thus synergistically boosting the N2 formation.

Published: May 2023

AbstractThe sluggish kinetics of oxygen reduction reaction (ORR) and unsatisfactory durability of Pt‐based catalysts are severely hindering the commercialization of proton‐exchange‐membrane fuel cells (PEMFCs). In this work, the lattice compressive strain of Pt‐skins imposed by Pt‐based intermetallic cores is tailored for highly effective ORR through the confinement effect of the activated nitrogen‐doped porous carbon (a‐NPC). The modulated pores of a‐NPC not only promote Pt‐based intermetallics with ultrasmall size (average size of <4 nm), but also efficiently stabilizes intermetallic nanoparticles and sufficient exposure of active sites during the ORR process. The optimized catalyst (L12‐Pt3Co@ML‐Pt/NPC10) achieves excellent mass activity (1.72 A mgPt−1) and specific activity (3.49 mA cmPt−2), which are 11‐ and 15‐fold that of commercial Pt/C, respectively. Besides, owing to the confinement effect of a‐NPC and protection of Pt‐skins, L12‐Pt3Co@ML‐Pt/NPC10 retains 98.1% mass activity after 30 000 cycles, and even 95% for 100 000 cycles, while Pt/C retains only 51.2% for 30 000 cycles. Rationalized by density functional theory, compared with other metals (Cr, Mn, Fe, and Zn), L12‐Pt3Co closer to the top of “volcano” induces a more suitable compressive strain and electronic structure on Pt‐skin, leading to an optimal oxygen adsorption energy and a remarkable ORR performance.
Polyimides Physically Crosslinked by Aromatic Molecules Exhibit Ultrahigh Energy Density at 200 °C

Published: May 2023

AbstractPolymer dielectrics possess significant advantages in electrostatic energy storage applications, such as high breakdown strength (Eb) and efficiency (η), while their discharged energy density (Ud) at high temperature is limited by the decrease in Eb and η. Several strategies including introducing inorganic components and crosslinking have been investigated to improve the Ud of polymer dielectrics, but new issues will be encountered, e.g., the sacrifice of flexibility, the degradation of the interfacial insulating property and the complex preparation process. In this work, 3D rigid aromatic molecules are introduced into aromatic polyimides to form physical crosslinking networks through electrostatic interactions between their oppositely charged phenyl groups. The dense physical crosslinking networks strengthen the polyimides to boost the Eb, and the aromatic molecules trap the charge carriers to suppress the loss, allowing the strategy to combine the advantages of inorganic incorporation and crosslinking. This study demonstrates that this strategy is well applicable to a number of representative aromatic polyimides, and ultrahigh Ud of 8.05 J cm−3 (150 °C) and 5.12 J cm−3 (200 °C) is achieved. Furthermore, the all‐organic composites exhibit stable performances during ultralong 105 charge–discharge cycles in harsh environments (500 MV m−1 and 200 °C) and prospects for large‐scale preparation.

Published: May 2023

AbstractNanowires are a promising structure to create new defect‐free heterostructures and optoelectronic devices. GaP nanowires grown via the VLS mechanism using tertiary‐butyl phosphine (TBP) and trimethylgallium (TMGa) as precursors in an in situ closed gas cell heating holder are shown. This holder is a model system to investigate the processes in metal‐organic vapour phase epitaxy (MOVPE). GaP nanowires change their growth direction after random distances by producing kinks. Statistics of these kink angles show dominant values of around 70.5°, 109.5°, and 123.7°. A custom holder tip capable of holding a single heating chip is used to perform scanning precession electron diffraction (SPED) measurements on the nanowire kinks. The results show that the predominant kink angles result from micro twins of first and second order. Understanding the defect formation and resulting geometry changes in GaP nanowires can lead to increased control over their shape during growth and mark a huge step toward applicable nanowire devices.

Published: May 2023

AbstractPlasmonics has been demonstrated to improve the performance of various optoelectronic devices operating in the infrared to visible wavelength regime. However, limited by optical properties of suitable plasmonic materials in ultraviolet (UV) regimes, rare works have been devoted to UV applications with plasmonic structures. This work deliberately fabricates a heterogeneous array of Al nanocaps (Al‐NC) on a wide‐bandgap semiconductor of GaN truncated nanocones (GaN‐TNC) and then presents a multifunctional plasmonic sensor for excellent UV photodetection and air‐quality‐index (AQI) gas sensing. As a UV photodetector, this work shows maximum responsivity (1.8 × 108 AW−1) and detectivity (1.2 × 1018 Jones) at the resonance wavelength of 355 nm, which based on the current knowledge, is the highest detectivity among GaN‐based UV photodetectors. Such a UV photodetector also introduces a decent response of rise time (78.3 ms) and fall time (303.5 ms), respectively. As a gas sensor, this work detects a key AQI gas of NO2 and provides a superior response of 28% and a detection limit of 500 ppb, respectively.

Published: May 2023

AbstractMetal oxide semiconductors have been developed for ultraviolet–visible photodetectors, but improving sensitivity has remained a challenge due to poor mobility and carrier losses. In this study, a high‐performance photodetector is achieved by implementing a chargeable electret to regulate carrier transmission properties in the CuBi2O4 (CBO) conductive channel. As expected, the positively charged device shows improved performance, with a broadband detection range covering 250–600 nm, maximum responsivity and detectivity of around 10.65 A W−1 and 8.56 × 1012 Jones, and a fast rise and decay time of 50 and 300 µs, respectively. Mechanism analyses suggest two roles of the electret layer: 1) positive charges in the electret layer attract electrons and leave a pure hole conductive channel with less carrier recombination and trapping; 2) holes in the conductive channel move in one direction with less carrier collision and scattering. This work has demonstrated an effective strategy for providing a durable and stable ultra‐high electrostatic field to improve the sensitivity of photodetectors.
