Influence of the Random Data Sampling in Estimation of Wind Speed Resource: Case Study

In this study, statistical analysis is performed in order to characterize wind speeds distribution according to different samples randomly drawn from wind speed data collected. The purpose of this study is to assess how random sampling influences the estimation quality of the shape (k) and scale (c) parameters of a Weibull distribution function. Five stations were chosen in West Africa for the study, namely: Accra Kotoka, Cotonou Cadjehoun, Kano Mallam Aminu, Lomé Tokoin and Ouagadougou airport. We used the energy factor method (EPF) to compute shape and scale parameters. Statistical indicators used to assess estimation accuracy are the root mean square error (RMSE) and relative percentage error (RPE). Study results show that good accuracy in Weibull parameters and power density estimation is obtained with sampled wind speed data of 30% for Accra, 20% for Cotonou, 80% for Kano, 20% for Lomé, and 20% for Ouagadougou site. This study showed that for wind potential assessing at a site, wind speed data random sampling is sufficient to calculate wind power density. This is very useful in wind energy exploitation development.
Collective actions in Catatumbo as a means for occupational reconfiguration of the agricultural sector

The armed conflict in Colombia has generated economic and social consequences that affect the understanding of local and regional development, bringing with them problems of land control in territories that have geostrategic advantages; such is the case of Catatumbo. Armed groups have entrenched themselves within this region, generating cultural rupture and limiting the occupational projects and hopes of its residents. This has resulted in a Territorial Vulnerability Index that reveals high rates of unemployment, violations of human rights and restrictions on processes of social participation. For this reason, this chapter analyzes the forms of collective resistance and their relationship with the changes in the productive and occupational practices of campesinos1 in the Catatumbo region. For this, it is important to analyze what is understood by collective action, occupational forms and the occupational expectations of a group of farmers, under a methodological framework of action research with three techniques of information collection: interviews, observation and workshops. The results made it possible to identify associativity, daily solidarity and strategic alliances as forms of resistance in the territory; collective actions that have determined the roles, personal history and occupational projections of its inhabitants based on individual and collective understandings, helping to reconfigure the territory and their occupations in search of alternatives for territorial development.
Toward Intercultural Competence: Using Expert Consensus to Identify Essential Personality Traits and Attitudes to Develop an Inclusive Extension Education Workforce

The rapid diversification of workforces and client stakeholder groups has prompted a growing emphasis on diversity, equity, and inclusion as a critical component of professional development across industry sectors. While the proliferation of intercultural competence training models has increased awareness among employers and workforces, the competencies advocated in these models may not always be relevant to an organization or institution’s operational context. This study addresses the need for contextually grounded intercultural competency models targeted to extension education contexts. Using a three-phased Delphi approach, data were gathered from a panel of 36 intercultural competency experts. The panel identified nine personal traits thought to be critical for the recruitment and development of culturally competent extension educators. The authors explain how these results may be used to recruit extension educators with traits conducive to engagement with a broad audience of stakeholders using culturally sensitive and responsive techniques. Given the distinct processes by which different components of intercultural competence are developed, we recommend specific measures and techniques administrators can utilize to recruit and develop extension educators who possess the agreed-upon intercultural personality traits.
Modeling the Relationship Between Occupational Accidents, Work-Family Conflict, and Quality of Work-Life in Emergency Room Nurses

Background: This study aimed to model the relationship between occupational accidents, work-family conflict, and quality of work-life in emergency room nurses. Materials and Methods: This correlational research uses path analysis. The study population consisted of all nurses working in the emergency rooms of hospitals in Tehran City, Iran, in 2020. Of them, 200 samples were selected by the available sampling method. To obtain the data, we used the occupational accidents questionnaire, the quality of work-life questionnaire, and the work-family conflict scale. SPSS v. 24 and Amos v. 24 software were used for data analysis. Results: The analysis of the findings showed that occupational accidents and work-family conflict have a negative and direct effect on the quality of work-life (P<0.01). Occupational accidents also have a positive and direct effect on work-family conflict (P<0.01). On the other hand, the mediating role of work-family conflict between occupational accidents and quality of work-life was confirmed (P<0.01). Conclusion: The relationship model of occupational accidents with quality of work-life mediated by work-family conflict has a good fit, and there is a relationship between family, job, and environmental stressors with the quality of work-life.
Bioactive Properties and Metabolite Profiles of Endolichenic Fungi in Mangrove Ecosystem of Negombo Lagoon, Sri Lanka

Endolichenic fungi (ELF) serve as a novel source of natural products with distinctive bioactivities. A total of 58 ELF isolated from 29 lichens collected from mangrove and mangrove-associated plants of Negombo lagoon, Sri Lanka were identified using morphological and DNA barcoding techniques. Ethyl acetate extracts of 18 such identified ELF isolates were subjected to in vitro assays to determine antioxidant, anti-inflammatory, tyrosinase inhibitory and antibacterial potency. Liquid chromatography–mass spectrometry (LC–MS) dereplication was conducted on the crude extracts in order to detect the secondary metabolites present. The extracts of Daldinia eschscholtzii and Hypoxylon lividipigmentum had the highest radical scavenging activity with SC50 values 14.27 ± 0.24 µg/mL and 18.34 ± 1.37 µg/mL, respectively. D. eschscholtzii also exhibited remarkable anti-inflammatory activity (IC50 7.97 ± 0.09 µg/mL). Tyrosinase inhibitory activity was highest in Cytospora xylocarpi (IC50 68.50 ± 0.34 µg/mL), while the highest activity against aerobic bacterial species Escherichia coli, Bacillus subtilis, Staphylococcus aureus and the anaerobic bacterial strain Streptococcus mutans was observed in the extracts of Xylaria feegenesis and Curvularia lunata. After a thorough study of the LC–MS profiles, it was found that the chemical profiles of Neofusicoccum occulatum, H. lividipigmentum and Myramaececium rubricosum were previously poorly explored in the literature.

Nitrogen-Enriched Porous Polyacrylonitrile-Based Carbon Fibers for CO2 Capture

Utilizing porous polyacrylonitrile (PAN) fibers as the precursors, porous carbon fibers were obtained by cross-linking of precursor fibers with hydrazine hydrate and subsequent heat treatment. A nitrogen content of more than 14 wt % was achieved in the carbon fibers. The porous carbon fiber that was prepared at low concentration of hydrazine hydrate (5 wt %) showed an optimal BET surface area of 277.4 m2/g with micro-/meso-/macropores. The CO2 adsorbed amount of this porous carbon fiber was 101 mg/g at 25 °C under atmospheric pressure, which was 2.1 times that of the fiber without cross-linking with hydrazine hydrate. In the simulated flue gas environment (10% CO2/90% N2), the adsorption capacity of the above-mentioned porous fiber was 32 mg/g at 25 °C, which was 1.4 times that of the fiber without cross-linking. These CO2 adsorption results demonstrated that the nitrogen functionalities and porous structure of the porous carbon fiber played an equivalent important role in the adsorption of CO2. The porou.
Improving carotenoid production in recombinant yeast, Saccharomyces cerevisiae, using ultrasound‐irradiated two‐phase extractive fermentation

Carotenoids are hydrophobic compounds that exhibit excellent bioactivity and can be produced by recombinant S. cerevisiae. Irradiating microorganisms with ultrasonic waves increase the productivity of various useful chemicals. Ultrasonic waves are also used to extract useful chemicals that accumulate in microbial cells. In this study, we aimed to improve the carotenoid production efficiency of a recombinant S. cerevisiae using an ultrasonic‐irradiation based two‐phase extractive fermentation process. When isopropyl myristate was used as the extraction solvent, a total of 264 mg/L of carotenoid was produced when batches were subjected to ultrasonic‐irradiation at 10 W, which was a 1.3‐fold increase when compared to the control. Transcriptome analysis suggested that one of the reasons for this improvement was an increase in the number of living cells. In fact, after 96 h of fermentation, the number of living cells increased by 1.4‐fold upon irradiation with ultrasonic waves. Consequently, we succeeded in improving the carotenoid production in a recombinant S. cerevisiae strain using a ultrasonic‐irradiated two‐phase extractive fermentation and isopropyl myristate as the solvent. This fermentation strategy has the potential to be widely applied during the production of hydrophobic chemicals in recombinant yeast, and future research is expected to further develop this process.
Inhibition mechanism on mango peels as organic inhibitor in 1 M HCl solution

In previous studies, mango peel skin can be used as raw material as an organic corrosion inhibitor. This research is a continuation of previous research. The raw materials used by mango skin peel with mango leather extract concentration are improved so that the optimized efficiency is more optimal. The tests that have been done in this research are polarization test, electrochemical test, and SEM. The extract concentration used was 2-6 ml, while the corrosion solution used was HCl 1 M. From the measurement results, it was found that the corrosion rate decreased to 1.774 mm/year. The highest efficiency inhibitory result is 81.77%. Electrochemical test results are not as good as polarization test results. This can happen because it has not reached the optimum concentration. From the polarization test indicates that the mechanism that occurs is anodic inhibiting mechanism. This is supported by the results of SEM testing performed. The SEM test results illustrate the presence of a thin layer formed on the surface of the material.In previous studies, mango peel skin can be used as raw material as an organic corrosion inhibitor.

Temporal variability and time compression of sediment yield in small Mediterranean catchments: impacts for land and water management

Increased soil erosion, pressure on agricultural land, and climate change highlight the need for new management methods to mitigate soil loss. Management strategies should utilize comparable data sets of long‐term soil erosion monitoring across multiple environments. Adaptive soil erosion management in regions with intense precipitation requires an understanding of inter‐annual variability in sediment yield (SY) at regional scales. Here, a novel approach is proposed for analysing regional SY. We aimed to (i) investigate factors controlling inter‐ and intra‐annual SY, (ii) combine seasonality and time compression analyses to explore SY variability and (iii) discuss management implications for different Mediterranean environments. Continuous SY measurements totalling 104 years for eight small catchments were used to describe SY variability, which ranged from 0 to 271 t/ha/year and 0 to 116 t/ha/month. Maximum SY occurs in spring to summer for catchments with oceanic climates, while semi‐arid or dry summer climates experience SY minimums. We identified three time compression patterns at each time scale. Time compression was most intense for catchments with minimum SY in spring to summer. Low time compression was linked to very high soil loss, low run‐off and sediment production thresholds, and high connectivity. Reforestation, grassland and terracing changed SY magnitudes and time compression, but failed to reduce SY for large storm events. Periods with a high probability of high SY were identified using a combination of intra‐annual SY variability, seasonality analysis, and time compression analysis. Focusing management practices on monthly flow events, which account for the majority of SY, will optimise returns in Mediterranean catchments.
Synthesis, characterization, crystal structure, thermal analysis of a new co-crystal supramolecular dinuclear zinc (II) complex containing chelidamate ligand

Abstract A new co-crystal supramolecular dinuclear compound of Zn(II) namely (dapH)2(hypydcH)2·[Zn2(hypydc)2(H2O)6]·2H2O (1), where [hypydcH2 = 4-hydroxypyridine-2,6-dicarboxylic acid (chelidamic acid), dap = 3,4-diaminopyridine] has been synthesized and characterized by elemental analysis, spectral (IR, UV–Vis), thermal (TG/DTG) analysis and single crystal X-ray diffraction. The zinc (II) cation sits on a center of inversion. In the crystal structure of 1, chelidamate dianions have been coordinated to ZnII ion in a three dentate fashion through two oxygen and one nitrogen atoms from (hypydc)2– ligands. Furthermore, dicarboxylic groups link two zinc (II) centers to each other via oxygen atoms of carboxylic groups, also three water molecules coordinated to metal centers. Consequently, each Zn(II) atom is seven-coordinate and demonstrate approximately pentagonal-bipyramidal ZnNO6 coordination geometry. The metal fragments are linked via the central four-membered Zn2O2 ring. Surprisingly, in 1 a proton transfer ion pair of chelidamic acid and 3,4-diaminpyridine crystallized accompanied with neutral dinuclear complex of Zn(II). Interestingly, the structural analysis illustrates that anionic and cationic fragment accompanied with neutral dinuclear complex and uncoordinated water molecules assemble the crystal structure of 1 into a fascinating supramolecular architecture.
Upgrading lignocellulosic waste to fuel by torrefaction: Characterisation and process optimization by response surface methodology

Torrefied biomass is a commercial fuel, which is particularly produced from woody biomass via torrefaction and alternative to coal to reduce greenhouse gas emissions in the short term. In this study, torrefaction conditions of cotton stalk were optimised, and the effect of bulk density together with temperature and residence time on process yields and characterisation of torrefied cotton stalk was investigated. Response surface methodology using Box‐Behnken design was employed for the design of experiments and optimization. Cotton stalk was torrefied at a temperature between 260°C and 320°C, in 10, 35, and 60 minutes with bulk density of 125, 150, and 175 kgm−3. Temperature was the most effective parameter for the six responses (higher heating value, carbon content, hydrogen/carbon and oxygen/carbon ratios, mass loss, and energy yield). Besides, temperature/bulk density interaction was found to be significant for all responses whereas residence time/bulk density interaction was effective for process yields. The optimization results showed that more economical torrefied biomass with similar quality of lignite could also be produced under process conditions of 305°C‐32 minutes‐158 kgm−3. At this point, higher heating value and carbon content of product were calculated as 19.7 MJ kg−1 and 64%, respectively.
Individual Evaluation vs Fact-checking in the Recognition and Willingness to Share Fake News About Covid-19 via Whatsapp

ABSTRACT The aim of the study is to research the effects of individual evaluation of fake and truthful news about COVID-19, compared to the exposure to fact-checking on the intention to share them via WhatsApp. An online experiment was conducted with a convenience sample of 819 Costa Ricans. Results show that people in the individual evaluation condition assess completely fake news with greater veracity and completely truthful information with less veracity, compared to the fact-checking condition. This response is more pronounced in the most religious people and among those most affected by structural inequalities in Costa Rican society (e.g., lower educational level, living on the coasts and lower subjective income). Finally, both the individual evaluation of disinformation content and exposure to fact-checking reduce the intention to share fake news about COVID-19 via WhatsApp.

Advantages of TiO2/carbon nanotube modified photocatalytic membranes in the purification of oil-in-water emulsions

For the effective purification of emulsified oil contaminated waters advanced treatment methods have to be applied, such as membrane filtration, which is able to eliminate macro-, and even nanoscale oil droplets, however, membrane fouling is still a major problem, which prevents economic utilization. Therefore, fouling mitigation is one of the most important aspects in the field of membrane separation developments. In the present study, solely TiO2 and TiO2/carbon nanotubes (CNT) composite modified PVDF membranes were prepared and used to purify oil-in-water emulsions. Achievable fluxes, reversible and irreversible filtration resistances, fouling models, filtration efficiencies and photocatalytic activities were compared in case of different nanomaterial covered and unmodified PVDF membranes. Applying either solely TiO2 or solely CNT coating resulted in the significant reduction of total filtration resistance in both cases, but the combination of the two components (TiO2 with 1 wt% CNT) resulted in by far the highest flux and lowest resistance, meanwhile, the enhanced photocatalytic efficiency of the composite was also achieved. To the best of our knowledge, this study demonstrates the beneficial effects of the combination of TiO2 and CNT nanomaterials for the first time in the field of membrane separation of oil-in-water emulsions.
