Mesoporous copper aluminate-modified tungsten trioxide nanocomposite for boosted photocatalytic H2 generation employing visible light exposure

Semiconductor photocatalysis is the most effective technology for producing “green” hydrogen, achieving sustainability to a high extent. Regrettably, the speedy re-pairing rate of photo-excited holes and electrons still represents the greatest challenge for developing heterogeneous photocatalysis. This contribution used a mixed surfactant-assisted hydrothermal route followed by an impregnation approach to construct mesoporous CuAl2O4/WO3 p-n heterojunction. Furthermore, a detailed investigation of the impact of CuAl2O4 (3.0–12.0 wt%) loading on the phase structure, surface composition, optical, textural, photo-caused charge carriers' separation ability, and photoactivity of WO3 material was provided. It was demonstrated that the constructed heterojunctions displayed improved visible-light-absorbance potential and photo-excited charge carriers' separation owing to reducing the bandgap to 2.15 eV and prompting charges' separation and transfer through forming step (S)-scheme p-n heterojunction. The 9.0 wt% CuAl2O4-loaded tungsten trioxide (1.2 g L–1) generated ∼ 18-fold as much hydrogen as the non-modified WO3 material. Additionally, when the photocatalyst dosage was raised from 1.2 to 1.8 g L–1, the H2 generation was augmented by 1.24 times with interesting sustainability through five consecutive cycles. This study opens the door to using this highly efficient, powerful, and sustainable material to solve numerous daily issues.

Comparative modeling of fluorescence and P700 induction kinetics for alga Scenedesmus sp. obliques and cyanobacterium Synechocystis sp. PCC 6803. Role of state 2-state 1 transitions and redox state of plastoquinone pool.

The model of thylakoid membrane system (T-M model) (Belyaeva et al. Photosynth Res 2019, 140:1-19) has been improved in order to analyze the induction data for dark-adapted samples of algal (Scenedesmus obliques) and cyanobacterial (Synechocystis sp. PCC 6803) cells. The fluorescence induction (FI) curves of Scenedesmus were measured at light exposures of 5 min, while FI and P700 redox transformations of Synechocystis were recorded in parallel for 100 s intervals. Kinetic data comprising the OJIP-SMT fluorescence induction and OABCDEF P700+ absorbance changes were used to study the processes underlying state transitions qT2→1 and qT1→2 associated with the increase/decrease in Chl fluorescence emission. A formula with the Hill kinetics (Ebenhöh et al. Philos Trans R Soc B 2014, 369:20130223) was introduced into the T-M model, with a new variable to imitate the flexible size of antenna AntM(t) associated with PSII. Simulations revealed that the light-harvesting capacity of PSII increases with a corresponding decrease for that of PSI upon the qT2→1 transition induced by plastoquinone (PQ) pool oxidation. The complete T-M model fittings were attained on Scenedesmus or Synechocystis fast waves OJIPS of FI, while SMT wave of FI was reproduced at intervals shorter than 5 min. Also the fast P700 redox transitions (OABC) for Synechocystis were fitted exactly. Reasonable sets of algal and cyanobacterial electron/proton transfer (ET/PT) parameters were found. In the case of Scenedesmus, ET/PT traits remained the same irrespective of modeling with or without qT2→1 transitions. Simulations indicated a high extent (20%) of the PQ pool reduction under dark conditions in Synechocystis compared to 2% in Scenedesmus.

The research design for the study was correlational. The population of the study was 250 staff of 10 agro based companies in Rivers State, Nigeria. The study sample was 100. The study adopted stratified random sampling technique in which 10 staff were chosen from each of the 10 agro based companies. The instrument for data collection was questionnaire, adapted in the modified likert scale of very high extent (4), high extent (3), low extent (2) and very low extent (1). The questionnaire was validated by a senior lecturer in Measurement and evaluation from Rivers State University, Nigeria. The reliability of the instrument was tested using Crombach Alpha and obtained .933>/71 which showed that the instrument was reliable. The study found that the three variables used in the study showed significant relationship with the development of agro based industries in Rivers State. The study concluded that communication, conceptualization and marketing skills significantly relate to development of agro based industries in Rivers State. The study recommended that among others, that teachers of Vocational and Technical Education Training (TVET) should emphasize to students the need to invest or conceptualize agro business plans in agro based businesses.

Utilization of Information Technology is an Elixir to Maximizing Efficiency in Business Organizations

This study has been able to justify the notion that the utilization of information technology is an elixir to maximizing efficiency of business organization. The paper used the qualitative approach applying survey design. The study purposively selects fifty (50) entrepreneurs and business owners to form the sampled subjects. The instrument for data collection used for this study was the close ended questionnaire with question items measured with the 4-likerts “Extent Format” (VHE, HE, LE, VLE). Conclusively, it was found that computers, mobile phone, computer software and internet are utilized for maximizing efficiency of business organizations to a high extent. Also, it was revealed that challenges as such infrastructural deficiencies, lack of maintenance culture, poor/no access to the internet and lack of skilled and competent ICT personnel has affected the utilization of information technology to a high extent. It recommended that business owners should ensure to put in place a standard ICT structure that will support effective and full utilization of information technology.

Spatio-temporal transcriptome and storage compound profiles of developing faba bean (Vicia faba) seed tissues.

Faba bean (Vicia faba) is a legume grown in diverse climate zones with a high potential for increased cultivation and use in food due to its nutritional seeds. In this study, we characterized seed tissue development in faba bean to identify key developmental processes; from embryo expansion at the expense of the endosperm to the maturing storage stages of the bean seed. A spatio-temporal transcriptome profiling analysis, combined with chemical nutrient analysis of protein, starch, and lipid, of endosperm and embryo tissues at different developmental stages, revealed gene expression patterns, transcriptional networks, and biochemical pathways in faba bean. We identified key players in the LAFL (LEC1, ABI3, FUS3, and LEC2) transcription factor network as well as their major repressors VAL1 and ASIL1. Our results showed that proteins accumulated not only in the embryo but also in the endosperm. Starch accumulated throughout seed development and oil content increased during seed development but at very low levels. The patterns of differentially expressed transcripts encoding proteins with functions in the corresponding metabolic pathways for the synthesis of these storage compounds, to a high extent, aligned with these findings. However, the early expression of transcripts encoding WRI1 combined with the late expression of oil body proteins indicated a not manifested high potential for lipid biosynthesis and oil storage. Altogether, this study contributes to increased knowledge regarding seed developmental processes applicable to future breeding methods and seed quality improvement for faba bean.

Oral symptoms in dying nursing home patients. Results from the prospective REDIC study

BackgroundThe mouth is a central organ for communication and fluid intake, also for dying nursing home patients. This study describes the prevalence and severity of oral symptoms from nursing home admission until the day of perceived dying and the day of death.MethodsA prospective, longitudinal cohort study including 696 patients who were admitted to 47 Norwegian nursing homes in 35 municipalities. During the first year of their stay, 189 died (27%), of whom 82 participants were assessed on the day they were perceived as dying and 134 on the day of death. Mouth care, nutrition, and bedsores were assessed with the Residents’ Assessment Instrument for nursing homes (RAI-NH) and palliative care (RAI-PC). Pain intensity was assessed with the Mobilization-Observation-Behaviour-Intensity-Dementia-2 Pain Scale (MOBID-2).ResultsThe proportion of patients with ≥ 6 oral symptoms increased from 16% when perceived as dying to 20% on the day of death (P = 0.001). On the day of death, xerostomia (66%), dysphagia (59%), and mastication problems (50%) were the most frequently observed oral symptoms. Only 16% received mouth care every hour and 12% were in pain during this procedure. Compared to people without dementia, those with a diagnosis of dementia at admission (N = 112, 86%) had xerostomia and mastication problems more frequently (50% vs. 73%; 32% vs. 56% (P = 0.038), respectively) on the day of death.ConclusionsThe high extent of oral symptoms such as xerostomia, dysphagia, and mastication problems underline the need for systematic assessment and improved oral palliative care for dying nursing home patients with dementia.Trial registrationClinicaltrials.gov NCT01920100 08/08/2013.

Tibia-first, gap-balanced patient-specific alignment technique achieves well-balanced gaps in 90% of cases by rebuilding bony anatomy within boundaries.

Patient-specific alignment (PSA) techniquetries to achieve balanced gaps and simultaneously rebuild the individual bony phenotype. The hypothesis was: PSA technique achieves balanced knees in a high percentage with more anatomical resections than adjusted mechanical alignment (AMA). Three hundred sixty-seven patients underwent navigated total knee arthroplasty (TKA) with a tibia-first gap-balanced PSA technique. Resection boundaries for medial proximal tibia angle (MPTA) of 86-92°, mechanical lateral distal femoral angle (mLDFA) of 86-92°, and hip-knee-ankle angle (HKA) of 175-185° were defined. Preoperative and intraoperative parameters of HKA, MPTA, mLDFA, and gap widths were recorded. Depending on the coronal deformity, the patients were divided into three groups: varus HKA < 178°; straight 178-182° and valgus HKA > 182°. The stability was analysed by assessing the difference between medial and lateral extension and flexion gaps as well as between flexion and extension gaps. All PSA measurements were compared with data from a previously published AMA series. PSA achieved balanced gaps in extension, flexion and between flexion/extension in over 90% of cases, being similar to AMA. In PSA, MPTA and mLDFA were restored within 1°, except in extreme varus (MPTA difference 2°) and valgus knees (mLDFA difference 3°). This was caused by the defined boundaries of the alignment technique. This individualised reconstruction led to significantly more anatomical resections of all tibia and femur resections. A tibia-first, gap-balanced PSA technique achieves balanced joints in more than 90% of cases. By maintaining preoperative MPTA and mLDFA to a high extent, far more anatomical resections, compared to AMA were performed. Future studies need to be conducted to investigate whether those promising intraoperative results correlate with postoperative patient outcomes and whether patients outside the 5° corridor have higher failure rates. Level III, retrospective cohort study.

Stigma in vitiligo: associated factors and severity strata of the Patient Unique Stigmatization Holistic tool in Dermatology (PUSH-D) score.

Vitiligo is the most common cause of skin depigmentation worldwide. Patients with vitiligo may experience stigma and this needs to be addressed. To evaluate stigma in patients with vitiligo, search for associated factors and establish severity strata for the Patient Unique Stigmatization Holistic tool in Dermatology (PUSH-D) for patients with vitiligo. We conducted a cross-sectional study in ComPaRe Vitiligo, an e-cohort of adult patients with vitiligo. Stigmatization was assessed using the PUSH-D, a recently validated dermatology-specific stigmatization assessment tool. We conducted univariate and multivariable linear regression to identify patient and disease factors associated with the stigmatization. We used an anchor-based approach to define severity strata for the PUSH-D. In total, 318 patients participated (mean age 49.7 years; 73.9% women). Fitzpatrick skin phototype IV-VI, severe facial involvement (high Self-Assessment Vitiligo Extent Score of the face) and depression (high Patient Health Questionnaire-9 score) were positively -associated with a higher stigmatization score, although this association was weak [r = 0.24 (P < 0.001) and r = 0.30 (P < 0.001), respectively]. PUSH-D cutoff values that best discriminated patients with high and low stigma, as defined by the anchor question, were 13 and 23 (κ = 0.622, 95% confidence interval 0.53-0.71). Our study is the first to use a skin-specific stigmatization tool to assess stigma in patients with vitiligo. Creating strata helps to better interpret the PUSH-D in daily practice and may facilitate its use in clinical trials.

Existence state of Ti in diamond-like carbon coatings and its effects on hybrid structure and residual stress: Molecular dynamics simulations

In this study, the modified embedded atom method potential function is selected via the LAMMPS platform and OVITO interface software to describe the interatomic interaction potential, which is used to simulate the existence states of doped Ti in Ti-doped diamond-like coatings as well as their effect on the hybrid structure, hardness, and residual stress of the coatings. The results indicate that Ti atoms preferentially combine with C atoms to form Ti–C bonds, thus rendering it difficult to form metallic Ti clusters. The formation of Ti-C bond clusters with high extent of ordering (nanoc-TiC) in the coating is related to the density (or sp3C fraction) of the coating; the higher the density, the higher is the critical content of Ti (CV-Ti) required to form nanoc-TiC. When the density of the coating ranges from 2.4 to 3.6 g/cm3, the CV-Ti is 2–6 at.%. When the Ti content in the coating is less than CV-Ti, Ti atoms existed only in amorphous Ti–C clusters, which is not conducive to the stability of the sp3C phase and significantly reduces the residual stress and hardness of the coating. When the CV-Ti is exceeded, nanoc-TiC formed and grew until the hybrid C–C bonds in the coating disappeared completely, thus increasing the residual stress of the coating.

Particulate iron oxide food colorants (E 172) during artificial digestion and their uptake and impact on intestinal cells

Iron oxide of various structures is frequently used as food colorant (E 172). The spectrum of colors ranges from yellow over orange, red, and brown to black, depending on the chemical structure of the material. E 172 is mostly sold as solid powder. Recent studies have demonstrated the presence of nanoscaled particles in E 172 samples, often to a very high extent. This makes it necessary to investigate the fate of these particles after oral uptake. In this study, 7 differently structured commercially available E 172 food colorants (2 x Yellow FeO(OH), 2 x Red Fe2O3, 1 x Orange Fe2O3 + FeO(OH) and 2 x Black Fe3O4) were investigated for particle dissolution, ion release, cellular uptake, crossing of the intestinal barrier and toxicological impact on intestinal cells. Dissolution was analyzed in water, cell culture medium and artificial digestion fluids. Small-angle X-ray scattering (SAXS) was employed for determination of the specific surface area of the colorants in the digestion fluids. Cellular uptake, transport and toxicological effects were studied using human differentiated Caco-2 cells as an in vitro model of the intestinal barrier. For all materials, a strong interaction with the intestinal cells was observed, albeit there was only a limited dissolution, and no toxic in vitro effects on human cells were recorded.

Restoration promotes ecological functioning through greater complementarity

Restoration projects are increasingly widespread and many promote habitat succession and the diversity and abundance of faunal communities. These positive effects on biodiversity and abundance may extend to enhancing the ecological functioning and resilience of previously degraded ecosystems, but this is rarely quantified. This study surveyed a 200‐ha restoring coastal wetland and three control wetlands in the Maroochy River, eastern Australia to compare the effects of wetland restoration on the consumption of carrion and the biodiversity, abundance, and functional diversity of functionally important fish and crustaceans. Carrion consumption by fish and crustaceans was measured every 6 months from spring 2017 until spring 2021 for nine events using a combination of baited cameras and scavenging assays. We found restoration improved rates of carrion consumption and the biodiversity, functional diversity, and abundance of scavenger species. Despite positive effects on the diversity of scavengers and carrion consumption, the abundance of two species, longfin eels (Anguilla reinhardtii) and mud crabs (Scylla serrata), was the most important predictors of carrion consumption rates. The spatial distribution of carrion consumption was concentrated in areas with high saltmarsh extent, moderate to high mangrove extent, and high salinity, which also resembled the distribution of both longfin eels and mud crabs. We show that restoration can promote the rates of key ecological functions but that increases to functions are likely to be characterized by low functional redundancy and greater complementarity. Therefore, maintaining or increasing the abundance of functionally important species should become a key objective in future restoration projects.

Enhanced output performance piezoelectric nanogenerators based on highly polarized PVDF/TBAHP tree-like nanofiber membranes for energy harvesting

As a piezo-polymer, the most contribution of polar phases (β-, γ-phases) to the piezoelectricity of polyvinylidene fluoride (PVDF) has been researched. Herein, a new type PVDF/tetrabutylammonium hexafluorophosphate (TBAHP) tree-like nanofiber membrane (TLNM) with high polar phase content and numerous fine branch fibers was successfully developed via electrospinning. PVDF-TLNMs exhibited mass branch fibers whose diameters of less than 50 nm. The β-phase content of 88.94 % disclosed piezoelectric polarization ability in the presence of TBAHP and tree-like structure. The best output current and voltage of flexible PVDF-TLNMs based piezoelectric nanogenerators (PENGs) could reach 2.04 μA and 4.08 V at 0.07 mol L−1 TBAHP, which increased the current of pure PVDF by approximately six times and a 217 % improvement to voltage output. Likewise, the peak power density of 0.07 mol L−1 PVDF-TLNM was 13 times above that of pure PVDF-NM. The significant reduction of internal resistance occurred after the addition of TBAHP. Such significant enhancements for electrical output depended on the high β-phase content, originated through TBAHP induced self-alignment of electric dipoles in PVDF polymer and high extent of mechanical drawing. The new kind of PVDF-TLNMs-base PENGs can provide a large scope for the ideas of smart wearable devices.

Tidal range electricity generation into the twenty-second century

Tidal range electricity generation schemes are designed to have a minimum operational life of at least 120 years, making it important to plan for changes such as sea-level rise (SLR). Earlier studies have shown that schemes can maintain the existing tidal range within the impoundment and protect areas from flooding. Here it is demonstrated that tidal range technology can maintain the current tidal extent despite SLR and suggests the operational strategies to achieve it. The approach is the only way to safeguard existing intertidal habitats. Mechanical and electrical plant requires a major overall, upgrade or replacement every 40 years; the levelised cost of energy is structured in 40-year periods reducing after the first period. Increasing the capacity or efficiency of the plant during the refits allows the protection of low-lying areas to be maintained and more electricity to be generated. The strategy requires energy to be used in pumping to achieve the current low tidal limits and the incoming tide to be curtailed to maintain the high tide extent, but there is very little effect on annual electricity production. Flexible operation can offer some protection from riverine flooding and existing inundation cycles can be maintained.

European Mobility Programs and Skills Development

This specific study follows the quantitative methodology approach and seeks to investigate primary education teachers’ perceptions of the skills developed through participation in European mobility programs. It examines whether there is a correlation between the perceptions of the following professional characteristics: knowledge of a foreign language, knowledge of information and communications technology (ICT), and participation in training programs for mobility. The research was conducted in the prefecture of Achaia in May 2023. The convenient sampling technique was applied, and 360 teachers finally completed the electronic questionnaire. Regarding data analysis, descriptive and inductive statistics were applied with the application of IBM SPSS v28 software. The internal consistency reliability for skills development from the European mobility programs is very satisfactory (Cronbach’s Alpha = 0.904 &gt; 0.70). Based on the findings of this study, it is shown that teachers recognize, to a very high extent, that they develop precious skills while participating in European mobility programs. Finally, their perceptions are reinforced by specific vocational traits.

Management of Higher Education Records and Record Keeping for Sustainable Quality Delivery in Captain Elechi Amadi Polytechnic, Rumuola, Rivers State, Nigeria

The study investigated the management of higher education records and record keeping for sustainable quality delivery in Rivers State, Nigeria. The study discussed records and records keeping in educational institutions especially, higher education. The article enumerated the purposes or importance of record management in higher institutions; some related literature were reviewed accordingly, theoretical framework was looked into and the study was achieved on record continuum theory by Funke Upward in 1990. The study highlighted some qualities of a good educational record keeping. The study found that good records management contributes significantly to administrators’ work performance and institutional performance in conclusion records keeping in tertiary institutions improves management performance to a very high extent. It was recommended among others that training programmes in the form of workshops, seminars, conferences be provided for administrative staff with regard to good records management in higher education. It is therefore a known fact that when records are well managed, utilized adequately and appropriately in higher institutions execution of management functions are likely to be easy, effective and sustainable.

This study assessed the extent of attitudes toward sustainable agriculture concepts and practices among students of School of Agriculture of Sulu State College during the Academic Year 2023-2024. With 100 samples taken through non-probability sampling method via purposive sampling, and with the use of weighted mean, standard deviation, ttest for independent samples, One-way ANOVA, and Pearson’s r, this study reveals the following findings: 1) Students of the School of agriculture of Sulu State College involved in this study are adequately represented in terms of gender, age, parent’s educational attainment, and parent’s average monthly income; 2) On the average, students of the School of Agriculture of Sulu State College expressed agreement that they have high extent of attitudes toward sustainable agriculture concepts and practices. 3) Generally, except for parent’s educational attainment, demographic profiles in terms of gender, age, and parents’ average monthly family income do not significantly mediate in ways how students of the School of Agriculture of Sulu State College assessed the extent of attitudes toward sustainable agriculture concepts and practice; 4) The group of agriculture students at the School of Agriculture of Sulu State College who assessed the extent of sustainable agricultural concepts in terms of Production efficiency as “Agree” or with High Extent could possibly be the same group of agriculture students at the School of Agriculture of Sulu State College who assessed the extents of Economic viability and Social responsibility as “Agree” or with High Extent, and Environmental sustainability as “Strongly Agree” or with Very High Extent, respectively; 5) This study seems to be aligned with Allahyari, M.S. (2008) model which is based on Connors et al. (2004) and Chen (2003) at the Ohio State University. The model is composed of the following constructs: production efficiency, economic viability, environmental sustainability and social responsibility.

Estimating forest extent across Mexico

Information on forest extent and tree cover is required to evaluate the status of natural resources, conservation practices, and environmental policies. The challenge is that different forest definitions, remote sensing-based (RSB) products, and data availability can lead to discrepancies in reporting total forest area. Consequently, errors in forest extent can be propagated into forest biomass and carbon estimates. Here, we present a simple approach to compare forest extent estimates from seven regional and global land or tree cover RSB products at 30 m resolution across Mexico. We found substantial differences in forest extent estimates for Mexico, ranging from 387 607 km2 to 675 239 km2. These differences were dependent on the RSB product and forest definition used. Next, we compared these RSB products with two independent forest inventory datasets at national (n = 26 220 plots) and local scales (n = 754 plots). The greatest accuracy among RSB products and forest inventory data was within the tropical moist forest (range 82%–95%), and the smallest was within the subtropical desert (range <10%–80%) and subtropical steppe ecological zones (range <10%–60%). We developed a forest extent agreement map by combining seven RSB products and identifying a consensus in their estimates. We found a forest area of 288 749 km2 with high forest extent agreement, and 340 661 km2 with medium forest extent agreement. The high-to-medium forest extent agreement of 629 410 km2 is comparable to the official national estimate of 656 920 km2. We found a high forest extent agreement across the Yucatan Peninsula and mountain areas in the Sierra Madre Oriental and Sierra Madre Occidental. The tropical dry forest and subtropical mountain system represent the two ecological zones with the highest areas of disagreement among RSB products. These findings show discrepancies in forest extent estimates across ecological zones in Mexico, where additional ground data and research are needed.
