The maintenance procedure of domestic civil aircraft has the problem of incomplete verification method,so it is necessary to study its verification method.According to the procedure type and content of aircraft maintenance manual technique,three verification methods are introduced.Based on the table-top verification method and on-object verification method from S1000D standard,two sub-methods of maintenance use verification and maintenance dedicated verification are proposed in combination with verification practice and conclusion of domestic civil aircraft,and their application ranges are described.The evaluation/simulation verification method and its four submethods are proposed,and verified with instance.T he results show that the proposed verification method of civil aircraft maintenance manual are effective,and are of reference significance for the development of aircraft maintenance manual verification.

In recent years, photothermal interface water evaporation technology has shown great application prospects due to its advantages of sustainability and high efficiency. With the rapid development of this frontier field, a variety of photothermal materials have been developed and widely explored. Among them, polyphenol-based photothermal materials are drawing great attention in the development of high-performance interface evaporators with their advantages of being green, economical, versatile, and scalable, leading the next hotspot and frontier. Therefore there is an urgent need to update the wider scientific community on recent advances in this field. In this review, three distinct functions of polyphenols including adhesion, secondary reactivity and photothermal properties are first discussed, since these functions are vital for designing photothermal interface evaporation systems (PIES). Furthermore, structure–activity relationships and the unique advantages of polyphenols in constructing PIES are emphasized in this part. Subsequently, according to the main functions of polyphenols in PIES, the roles of polyphenols are introduced and categorized into four application forms: (a) as intermediate layers to introduce photothermal materials; (b) realizing hydrophilic modification in PIES; (c) as photothermal materials without substrates in PIES; (d) as photothermal coatings. Then some representative applications of polyphenols such as achieving confinement capillarity, designing complex 3D evaporators, and constructing multifunctional PIES are highlighted, which can further exhibit the distinct advantages of green polyphenol-based photothermal materials in improving the water evaporation performance. Finally, the challenges and opportunities for the future development of polyphenol-based interfacial water treatment for freshwater production are discussed. [ABSTRACT FROM AUTHOR]

Objectives: This systematic review and meta‐analysis aimed to determine the prevalence of loneliness and social isolation among informal carers of individuals with dementia and to identify potential influencing factors. Methods: We conducted a comprehensive search across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, CINAHL, Scopus, Chinese Biomedical, China National Knowledge Internet, and WANFANG. Our search strategy covered the inception of the databases up to September 16, 2023, with an updated search conducted on March 8, 2024. Prevalence estimates of loneliness and social isolation, presented with 95% confidence intervals, were synthesized through meta‐analysis. Subgroup analyses and meta‐regression were employed to explore potential moderating variables and heterogeneity. Results: The study encompassed 27 research papers involving 11,134 informal carers from 17 different countries. The pooled prevalence of loneliness among informal carers of individuals with dementia was 50.8% (95% CI: 41.8%–59.8%), while the pooled prevalence of social isolation was 37.1% (95% CI: 26.7%–47.6%). Subgroup analyses and meta‐regression indicated that various factors significantly influenced the prevalence of loneliness and social isolation. These factors included the caregiving setting, study design, the intensity of loneliness, geographical location (continent), data collection time, and the choice of assessment tools. Conclusions: This study underscores the substantial prevalence of loneliness and social isolation among informal carers of individuals with dementia. It suggests that policymakers and healthcare providers should prioritize the development of targeted interventions and support systems to alleviate loneliness and social isolation within this vulnerable population. Key points: Informal carers of people with dementia contend with unique circumstances that render them susceptible to both loneliness and social isolation.There is a significant prevalence of loneliness and social isolation in informal carers of individuals with dementia.Several significant moderators influence the prevalence of loneliness and social isolation among informal carers of individuals with dementia.Moderator analysis can guide targeted interventions and support systems for at‐risk informal carers of people with dementia to alleviate loneliness and social isolation.

A β-naphthol-modified hyper-cross-linked resin HJ-G10 was synthesized, characterized, and evaluated for adsorption ofp-aminobenzoic acid from aqueous solutions. The adsorption was effective and a higher temperature was more favorable. The Freundlich equation characterized the equilibrium data better, the calculated isosteric enthalpy was positive and decreased with increasing of the equilibrium adsorption amount. The molecular form ofp-aminobenzoic acid was favorable for the adsorption and the adsorption in acidic solution was relatively more effective. The pseudo-second-order rate equation fitted the kinetic curves better than the pseudo-first-order rate equation. [ABSTRACT FROM PUBLISHER]

3D printing technology is promising in creating specialized functional foods, such as high-protein and high dietary fiber noodles. In this study, chicken breast-based noodles with varying proportions of oat bran and konjac flour were developed. The research analyzed the physicochemical, digestive properties, and 3D printability of these chicken-based doughs and noodles. The results indicated that the inclusion of fiber-rich flours notably enhanced dough viscosity and viscoelasticity. However, exceeding 4 % konjac flour negatively affected cooking quality and texture due to its strong water absorption capacity. The experimental group with fiber-rich flours exhibited prolonged starch/protein digestion time compared to the Control group. The increased ability to bind water in the fiber rich formula likely restricted water mobility, affecting mass transition in the "water channel". Notably, chicken noodles fortified with 6 % oat bran and 2 % konjac flour displayed the highest 3D printability. These results offer valuable insights for the industry in selecting appropriate dietary fiber sources for the development of nutritionally balanced 3D-printed meal options., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

Human gut commensal bacteria are routinely exposed to various stresses, including therapeutic drugs, and collateral effects are difficult to predict. To systematically interrogate community-level effects of drug perturbations, we screened stool-derived in vitro communities with 707 clinically relevant small molecules. Across ∼5,000 community-drug interaction conditions, compositional and metabolomic responses were predictably impacted by nutrient competition, with certain species exhibiting improved growth due to adverse impacts on competitors. Changes to community composition were generally reversed by reseeding with the original community, although occasionally species promotion was long-lasting, due to higher-order interactions, even when the competitor was reseeded. Despite strong selection pressures, emergence of resistance within communities was infrequent. Finally, while qualitative species responses to drug perturbations were conserved across community contexts, nutrient competition quantitatively affected their abundances, consistent with predictions of consumer-resource models. Our study reveals that quantitative understanding of the interaction landscape, particularly nutrient competition, can be used to anticipate and potentially mitigate side effects of drug treatment on the gut microbiota.
