Published: July 2023

O presente artigo apresenta os resultados de pesquisa empírica na qual objetivamos compreender como o risco associado ao fenômeno migratório no contexto das Mudanças Climáticas foi construído em conteúdos de produtos jornalísticos da mídia de referência e da mídia alternativa, no ano de 2018. Acionamos o conceito de frame (ENTMAN, 1993) para identificar a saliência dada ao risco nos 125 conteúdos analisados, constatando que a noção de risco foi destacada em praticamente toda a amostra. Ao enquadrar determinado aspecto da realidade em um texto comunicativo é proposta uma interpretação causal. Refletimos sobre a importância do jornalismo na formação de uma opinião pública consciente da complexidade do fenômeno, uma vez que a visibilidade dada ao tema reflete na sua percepção junto à audiência. A atividade jornalística também desempenha papel importante no processo da Comunicação de Risco de Desastres (CRD) podendo contribuir com a construção de comunidades resilientes, já que comunidades informadas têm maior capacidade de reagir aos eventos extremos.

Pediculosis capitis is an ectoparasitosis that is present worldwide, with highest prevalence among schoolchildren. This parasitosis has been correlated with socioeconomic factors and individual aspects of the host, such as sex and hair characteristics. In Brazil, it has been estimated that this disease occurs in about 30% of school-age children. Based on this, the aim of this study was to evaluate the prevalence of pediculosis among schoolchildren in the city of Niterói, in the State of Rio de Janeiro (RJ), besides analyzing the relationship between positivity and the characteristics of the participating individuals. The study included 244 students from the first to the fifth grades of elementary school who underwent a scalp aspiration procedure in order to diagnose parasitosis cases. Information regarding sex, self-declared skin color, hair length and color, and curl type was collected from each participant. Statistical analysis was performed using Fisher’s exact test and logistic regression. The overall prevalence of pediculosis was 19.7%, and it was more frequent in females, with a statistically significant difference (p < 0.001). There were also statistically significant associations between positivity for infestation and the hair length (p < 0.001) and with the hair structure (p = 0.019). Being an afro-descendant, not being female and having dark hair, together, was a protective factor against pediculosis among schoolchildren. This study evidenced that the host’s sex and physical characteristics showed direct relationships with lice infestation, although it was not possible to put forward a robust model for determining the presence of pediculosis. These results point to the notion that this ectoparasitosis is a multifactor disease.

Financial forest resources consist are composed of the financial benefits coming from its exploitation, the credits made available used by the Forestry Administration and funds offered by Technical and Financial Partners of the State. The determination, allocation and use of these financial resources follows a different procedure within the Ministry of the Environment and Sustainable Development (including the Forestry Administration) and the Ministry of Economy and Finance. The objective of this study is therefore to analyze the procedures of the management of these financial resources in order to know how they contribute to the sustainability of this sector. In this point of view, the SWOT method will allow us to analyze the concerned procedure and to determine its contribution for the sustainable management of the forest.
Assessing the applicability of changepoint analysis to analyse short-term growth
Authors: Gasparatos Nikolaos , Scheffler Christiane , Hermanussen Michael
Published: July 2023

Background: Assessing short-term growth in humans is still fraught with difficulties. Especially when looking for small variations and increments, such as mini growth spurts, high precision instruments or frequent measurements are necessary. Daily measurements however require a lot of effort, both for anthropologists and for the subjects. Therefore, new sophisticated approaches are needed that reduce fluctuations and reveal underlying patterns.
Objectives: Changepoints are abrupt variations in the properties of time series data. In the context of growth, such variations could be variation in mean height. By adjusting the variance and using different growth models, we assessed the ability of changepoint analysis to analyse short-term growth and detect mini growth spurts.
Sample and Methods: We performed Bayesian changepoint analysis on simulated growth data using the bcp package in R. Simulated growth patterns included stasis, linear growth, catch-up growth, and mini growth spurts. Specificity and a normalised variant of the Matthews correlation coefficient (MCC) were used to assess the algorithm’s performance. Welch’s t-test was used to compare differences of the mean.
Results: First results show that changepoint analysis can detect mini growth spurts. However, the ability to detect mini growth spurts is highly dependent on measurement error. Data preparation, such as ranking and rotating time series data, showed negligible improvements. Missing data was an issue and may affect the prediction quality of the classification metrics.
Conclusion: Changepoint analysis is a promising tool to analyse short-term growth. However, further optimisation and analysis of real growth data is needed to make broader generalisations.
Amphibian Species Decline in Pune City
Authors: Padhye A. D. , Mahabaleshwarkar Mukund
Published: July 2023

Amphibians are excellent indicators of environmental health due to their sensitivity to temperature, humidity, and pollution. Their sedentary nature makes them vulnerable to changes in their population. Pune's rapid industrialization and urbanization have severely impacted the amphibian fauna in the city and its outskirts. A survey conducted in 2000 identified 14 amphibian species belonging to 7 genera and 4 families. However, several species have either disappeared or are now found only outside the city or beyond 10 km from the city center. The decline in amphibian populations is mainly attributed to habitat loss caused by urban expansion, construction, and encroachment. The loss of critical breeding grounds, such as paddy fields and rainwater pools, has further contributed to their decline. The inclusion of fringe villages into the municipal limits will exacerbate habitat destruction. Conservation efforts, such as protecting breeding sites and collaborating with government bodies and NGOs, are essential to preserve these vulnerable amphibians in the region.

Published: July 2023

The traditional hawthorn product market is shrinking year by year, and there is a serious contradiction between supply and demand. The blackening reaction can not only change the original quality of hawthorn, but also provide a new way for hawthorn processing. In this paper, hawthorn was used as raw material, processed by blackening technology, and sensory evaluation is used as an index to optimize the process of sugar liquid immersion pre-treatment by single factor experiment and response surface methodology. The results showed that the optimal process parameters: sucrose concentration of 60%, immersion time of 32h, solid-liquid ratio of 1:2.3, and immersion temperature of 38℃. Under this condition, the sensory score of blackened hawthorns was 98.14±0.03. The blackened hawthorn produced by this process had uniform colour, moderate hardness, strong chewiness.

Framing Anticolonialism in Evaluation: Bridging Decolonizing Methodologies and Culturally Responsive Evaluation
Authors: Jordan Lorien , Hall Jori
Published: July 2023

Background: Evaluation is grounded in academically imperialistic research methodologies, paradigms, and epistemologies, which have lasting effects on communities of study. Confronting Westernized evaluation's monoculturalism, scholars call for decolonization, to produce locally-determined, strengths-based, culturally-situated, and valid understandings. This endeavor is complicated, requiring a paradigm shift for Westernized evaluators.  Purpose: In this paper, we describe the anticolonial culturally responsive framework occurring in the intersections between culturally responsive (CRE) and decolonizing (DF) approaches. Anticolonialism honors decolonizing without displacing the authority of Indigeneity, simultaneously foregrounding the interweaving of evaluator, evaluand, and disciplinary culture. Interrogating academic imperialism through anticolonialism, confronts the social processes and cultural ideologies that produce and reproduce social inequality in evaluations. Setting: Not applicable. Data Collection and Analysis: We draw on scholars and scholarship who have advanced culturally responsive, decolonizing, and anticolonial evaluation and methodological fields.   Findings: The anticolonial culturally responsive framework is an invitation for evaluators trained in imperialistic Westernized approaches or who embody the colonial world through our race, language, knowledge, and culture. Our goal is not to displace the primacy and urgency of vitalizing Indigenous and decolonizing frameworks. Instead, we offer a tentative approach committed to pluriversality, justice, self-determination, and the possibility of collaboration between knowledge systems and knowers.

One of the most interesting discussions related to Christian Anthropology is human sexuality, especially the relationship between men and women. The Church also concerns about the relationship between men and women. This is inseparable from the Church's reflection on the dignity, rights and obligations of women in various fields of society and the Church. Through this paper, the author would like to focus on the role of women in the Church, especially the Church's attitude towards the role of women. The author will look at the main basis in Christian Anthropology, namely the story of the creation of men and women.
Theoretical Investigation on Monomer and Dimers of Inhibitor of Cytochrome P450 Enzymes: 1-Aminobenzotriazole
Authors: Manzur María E. , Cataldo Pablo G. , Iramain Maximiliano A. , Castillo María V. , Brandán Silvia Antonia
Published: July 2023

In this research, structures and properties of monomer and two dimers (1 and 2) of inhibitor of cytochrome P450 enzymes, 1-Aminobenzotriazole (ABT) have been studied by using functional hybrid B3LYP/6-311++G** calculations. The very good correlations observed between theoretical and experimental 1H-, 13C-NMR, FT-IR and FT-Raman spectra suggest that C-H···N interactions of dimeric species should be expected in the solid phase, as was observed in the experimental crystalline structure of a quinolin benzotriazole derivative. NBO and AIM calculations suggest that dimer 2 with inverted positions of its monomers could be present in the solid phase because it evidence higher stabilities in both media. On the other hand, frontier orbitals studies support a higher reactivity of dimer 2 of ABT higher than the monomer and dimer 1, for which, the presence of dimer 2 containing N-NH2 groups in ABT could justify the biological activities observed for this species with gap values between 4.5933 and 4.8164 eV different from antiviral agents containing the C-NH2 moiety, as amantadine and chloroquine whose gap values are around 4.3012-4.1116 eV. Finally, the presence of bands of monomer and of both dimers are predicted in the vibrational spectra and, hence, its completes assignments have been performed. The scaled force constants for the three studied species are also reported.
Submarine Cables: Issues of Maritime Security, Jurisdiction, and Legalities
Authors: Pandey Shivam Kumar , Bhushan Aditya
Published: July 2023

This paper delves into the complex issues surrounding submarine cables, vital for global communication and data exchange. These issues include maritime security, legal jurisdictions, and broader legalities. Because submarine cables are located deep in the world's oceans, they face numerous security threats such as sabotage, illegal fishing, and deep-sea mining, highlighting the need for comprehensive maritime security measures. Legal Jurisdiction over these cables, especially those outside territorial waters, is equally complicated. Different international norms and regulations contribute to a fragmented legal landscape, creating jurisdictional authority and regulatory compliance ambiguities. Moreover, international laws offer inconsistent solutions to cable damage, repair, and maintenance, adding further complexity. This paper examines these interconnected issues, analyzing the existing regulatory frameworks and their effectiveness in addressing submarine cables' security and legal challenges. We provide a nuanced understanding of this essential infrastructure's vulnerabilities and propose recommendations for enhanced legal frameworks, increased international cooperation, and improved security measures. This comprehensive study is particularly relevant in the current era of digital interconnectedness, where reliable, secure, and uninterrupted international data flows are crucial. We hope this paper will stimulate further discussion and research in this critical yet often underestimated international law and global security area.

Published: July 2023

Rapid development of eco-tourism is reflected in an almost equally rapid growth in the number of researchers who draw attention to potentially detrimental and destructive consequences of tourism growth. Sustainable tourism and eco-tourism destinations are crucially important for sustainable development, which has emerged as a logical need to stop the accelerated economic growth based on unlimited exploitation of available resources. In this paper, the focus is on the ecological aspects of sustainable tourism development, with a special emphasis on the application of ecotourism in ecotourism destinations and the motivation of tourists in ecotourism. Ecotourism represents a specific form of tourism aimed at preserving natural resources and promoting sustainable development. Ecotourism destinations are of particular importance in the promotion of ecological principles in tourism. In this paper, the paper analyzes the factors applied in ecotourism, with the aim of improving the sustainable development of tourism. Also, the motives of tourists for participating in ecotourism are considered, as well as the ways in which ecotourism destinations can improve their offer in order to attract tourists. Special emphasis is placed on the ecological aspects of the sustainable development of tourism and the ways in which tourism can influence the preservation of natural resources and the protection of the environment.
Intercultural approach to English language teaching: Advantages and challenges
Authors: Bakić-Mirić Nataša , Jevrić Tamara , Ratković-Stevović Jelena
Published: July 2023

In the 21st century, teaching and learning a foreign language obviously includes teaching and learning about culture. In this regard, a new method of teaching English has emerged that is equally focused on language and culture. Teaching English through an intercultural approach actually teaches students about cultures by developing their intercultural communicative competence while at the same time developing their language skills. Although this approach to English language teaching is relatively new, this paper will analyze the basic principles of an intercultural approach to English language teaching, lesson planning, and textbook selection. An intercultural approach to teaching English enables students to understand the differences that can occur in communication between people coming from the English-speaking world; develop skills, attitudes and awareness of different values; beliefs and worldviews in these cultures, at the same time improving language competence and skills as well as getting to know one's own culture. In the real world, however, it should be borne in mind that the acquisition of intercultural competence is never complete and perfect. A successful intercultural communicator does not require perfect knowledge of English and/or cultural competence. There is no perfect model for successful teaching and learning intercultural competence, as there is no complete definition of what an intercultural approach to English language teaching actually encompasses, and whether it is possible to assess objectively students' knowledge upon completion of the course. However, as the world inevitably becomes culturally diverse due to migration for economic and/or political reasons, it is vital that students accumulate intercultural knowledge in a foreign language course, which certainly poses a challenge for the language teachers.
Theoretical considerations of romanticism
Authors: Aleksić Slađana
Published: July 2023

The changes brought about by romanticism in the understanding of literature do not mean only the end of the classicist period. By destroying normativity as a form of relationship to creativity, the romantics emphasized the principle: as many writers as many sources of rules. Hence, the way was opened to the predominance of another poetics, descriptive, which has remained dominant even in our time. One of the most important results that romanticism brought in the study of literature is the orientation towards the study of concrete literary phenomena. This orientation brings to the fore the possibilities of studying concrete phenomena offered by the disciplines of literary criticism and literary history. The paper presents romantic poetic attitudes and theoretical considerations of romanticism.

Contribuições da psicossomática psicanalítica à clínica contemporânea
Authors: Béjar Victoria Regina
Published: July 2023

A autora enfatiza as contribuições da psicossomática psicanalítica da Escola de Paris para a compreensão do funcionamento psíquico dos pacientes com somatizações e doenças graves. Tais descobertas são úteis para a compreensão das estruturas não neuróticas, nas quais os processos de simbolização e da constituição do narcisismo primário encontram-se comprometidos. Uma das principais questões em comum nas somatizações graves e nas demais manifestações clínicas das não neuroses, são matrizes traumáticas precoces decorrentes de déficits da relação mãe bebê. Estabelece conjecturas sobre as diferentes manifestações clínicas, aos excessos de ausência ou de presença do objeto externo. Apresenta conceitos como a função materna, com suas dimensões de paraexcitação e de libidinização e censura da amante. Descreve a metapsicologia do corpo pulsional da estrutura psicossomática e suas vicissitudes nas desorganizações progressivas. Utiliza vinhetas clínicas para ilustrar a racionalização excessiva do funcionamento operatório e o resfriamento afetivo da depressão essencial nas estruturas não neuróticas, como as somatizações, adicçõess e comportamentos violentos.
Por uma clínica não fetichizada
Authors: Giovannetti Marcio de Freitas
Published: July 2023

Noventa anos depois do ensaio de Freud: Inibição, sintomas e angustia e cinquenta anos depois do seminário de Lacan sobre a angústia, o autor propõe que o psicanalista encare a própria angústia inerente a um trabalho e profissão cujas bases estão sempre em questionamento. Preconiza que o psicanalista procure não se defender da angústia fetichizando e sacralizando os conceitos elaborados pelos seus predecessores. O autor defende a ideia de que, na atualidade, as pessoas buscam encontrar no analista um interlocutor pessoal, que seja capaz de acolher e significar sua angústia frente a um mundo sem referenciais estáveis, não mais fascinadas pela ideia de um inconsciente, como no passado.

Behavioral entrainment to rhythmic auditory stimulation can be modulated by tACS depending on the electrical stimulation field properties
Authors: Cabral-Calderin Yuranny , van Hinsberg Daniela , Thielscher Axel , Henry Molly J
Published: July 2023

Synchronization between auditory stimuli and brain rhythms is beneficial for perception. In principle, auditory perception could be improved by facilitating neural entrainment to sounds via brain stimulation. However, high inter-individual variability of brain stimulation effects questions the usefulness of this approach. Here we aimed to modulate auditory perception by modulating neural entrainment to frequency modulated (FM) sounds using transcranial alternating current stimulation (tACS). In addition, we evaluated the advantage of using tACS montages spatially optimized for each individual’s anatomy and functional data compared to a standard montage applied to all participants. Across two different sessions, 2 Hz tACS was applied targeting auditory brain regions. Concurrent with tACS, participants listened to FM stimuli with modulation rate matching the tACS frequency but with different phase lags relative to the tACS, and detected silent gaps embedded in the FM sound. We observed that tACS modulated the strength of behavioral entrainment to the FM sound in a phase-lag specific manner. Both the optimal tACS lag and the magnitude of the tACS effect were variable across participants and sessions. Inter-individual variability of tACS effects was best explained by the strength of the inward electric field, depending on the field focality and proximity to the target brain region. Although additional evidence is necessary, our results also provided suggestive insights that spatially optimizing the electrode montage could be a promising tool to reduce inter-individual variability of tACS effects. This work demonstrates that tACS effectively modulates entrainment to sounds depending on the optimality of the electric field. However, the lack of reliability on optimal tACS lags calls for caution when planning tACS experiments based on separate sessions.

Importance

Maternal labor epidural analgesia (LEA) and oxytocin use for labor and delivery have been reported to be associated with child autism spectrum disorders (ASD). However, it remains unclear whether these 2 common medications used during labor and delivery have synergistic associations with ASD risk in children.

Objective

To assess the independent associations of LEA and oxytocin during labor and delivery with ASD, as well as outcome modification associated with the concurrent use of both interventions.

Design, Setting, and Participants

Data for this cohort study included 205 994 singleton births with vaginal deliveries in a single integrated health care system in Southern California from calendar years 2008 to 2017. Children were followed up to December 31, 2021. Data on use of LEA and oxytocin, covariates, and ASD outcome in children were obtained from electronic medical records. Cox proportional hazards regression was used to estimate the hazard ratios (HRs) adjusting for covariates.

Exposures

Labor epidural analgesia and/or oxytocin use during labor and delivery.

Main Outcomes and Measures

A child’s clinical diagnosis of ASD during follow-up and at age of diagnosis.

Results

Among the cohort, 153 880 children (74.7%) were exposed to maternal LEA and 117 808 children (57.2%) were exposed to oxytocin during labor and delivery. The population of children was approximately half boys and half girls. The median (IQR) age of the mothers was 30.8 (26.8-34.5) years for those not exposed to LEA, 30.0 (25.9-33.8) years for those exposed to LEA, 30.4 (26.5-34.1) years for those unexposed to oxytocin, and 30.0 (25.9-33.9) years for those exposed to oxytocin during labor and delivery. A total of 5146 children (2.5%) had ASD diagnosed during follow-up. Oxytocin exposure was higher among LEA-exposed (67.7%) than -unexposed (26.1%) children. The ASD risk associated with LEA was independent of oxytocin exposure (HR, 1.28; 95% CI, 1.18-1.38); however, the ASD risk associated with oxytocin was not significant after adjusting for LEA exposure (HR, 1.05; 95% CI, 0.99-1.12). A significant interaction of LEA and oxytocin on child ASD risk was found (P = .02 for interaction). Compared with no exposure, HRs were 1.20 (95% CI, 1.09-1.32) for LEA alone, 1.30 (95% CI, 1.20-1.42) for both LEA and oxytocin, and 0.90 (95% CI, 0.78-1.04) for oxytocin alone.

Conclusions and Relevance

The findings of this cohort study suggest an association between maternal LEA and ASD risk in children, and the risk appeared to be further increased if oxytocin was also administered. Oxytocin exposure without LEA exposure was not associated with ASD risk in children. These findings must be interpreted with caution. Further studies are needed to replicate or refute the study results and examine biological plausibility.
Making Ternary‐Metal Hydroxysulfide Catalyst via Cathodic Reconstruction with Ion Regulation for Industrial‐Level Hydrogen Generation
Authors: Fang Peng , Zhu Mingze , Liu Jiao , Zhu Zexuan , Hu Jingguo , Xu Xiaoyong
Published: July 2023

Deep insight into electrochemical reconstruction aids in the decoding of electrocatalytic mechanisms and the development of design principles for advanced catalysts. Despite recent achievements, research concerning cathodic reconstruction is still lacking compared to the anodic variety. This work captures the electroreductive reconstruction dynamics over bimetal Ni–Mo sulfide by various in/ex situ techniques, and whereby cathodic reconstruction is steered with ion regulation to achieve a heterogeneous Ni–Mo–Fe ternary metal hydroxysulfide (NMFSOH) as a robust hydrogen‐evolving catalyst that is competent in industrial‐level water electrolysis. The thermodynamically adaptive heterosynergism in the resultant NMFSOH catalyst can coordinate water dissociation and hydrogenation for the alkaline hydrogen evolution reaction even at high current densities. A flow‐type alkaline water electrolyzer with dual NMFSOH electrodes affords an electricity consumption of 3.99 kW h Nm−3 and an electricity‐to‐hydrogen efficiency of 88.7%, manifesting its competitive cost‐effectiveness toward practical applications. This study showcases ion‐regulatory reconstruction as an effective strategy to construct high‐performance electrocatalysts.

Published: July 2023

Serotonin (5‐hydroxytryptamine) acts as a widespread neuromodulator in the nervous system of vertebrates and invertebrates. In insects, it promotes feeding, enhances olfactory sensitivity, modulates aggressive behavior, and, in the central complex of Drosophila, serves a role in sleep homeostasis. In addition to a role in sleep‐wake regulation, the central complex has a prominent role in spatial orientation, goal‐directed locomotion, and navigation vector memory. To further understand the role of serotonergic signaling in this brain area, we analyzed the distribution and identity of serotonin‐immunoreactive neurons across a wide range of insect species. While one bilateral pair of tangential neurons innervating the central body was present in all species studied, a second type was labeled in all neopterans but not in dragonflies and firebrats. Both cell types show conserved major fiber trajectories but taxon‐specific differences in dendritic targets outside the central body and axonal terminals in the central body, noduli, and lateral accessory lobes. In addition, numerous tangential neurons of the protocerebral bridge were labeled in all studied polyneopteran species except for Phasmatodea, but not in Holometabola. Lepidoptera and Diptera showed additional labeling of two bilateral pairs of neurons of a third type. The presence of serotonin in systems of columnar neurons apparently evolved independently in dragonflies and desert locusts. The data suggest distinct evolutionary changes in the composition of serotonin‐immunolabeled neurons of the central complex and provides a promising basis for a phylogenetic study in a wider range of arthropod species.

Published: July 2023

The reactive collision between 36Ar and the 36ArH+ species has been investigated by means of quantum mechanical (QM), quasiclassical trajectories (QCT) and statistical quantum mechanical (SQM) approaches. Reaction probabilities, cross sections as a function of the energy and rate constants in terms of the temperature have been obtained. Cumulative distributions as a function of the collision time and the inspection of selected QCT corresponding to specific dynamical mechanisms have been analysed. Predictions by means of the SQM method are in good agreement with the QM results, thus supporting the complex‐forming nature of the process.

Published: July 2023

Lenvatinib is a medication that targets multiple tyrosine kinases and is commonly used to treat various types of cancer. With its frequent usage, monitoring and assessing its potential adverse effects has become crucial. This study utilizes the US Food and Drug Administration Adverse Event Reporting System (FAERS) database to analyze the possible link between lenvatinib and gastrointestinal perforation. FAERS was used to analyze adverse drug reactions (ADRs) linked with lenvatinib from the first quarter of 2015 to the last quarter of 2022. The association between lenvatinib and gastrointestinal perforation was evaluated using disproportionality analyses. This study included 464 patients who developed gastrointestinal perforation after using lenvatinib. Perforation involved the entire digestive tract, with the colon among the most commonly affected perforation sites, and previously undetected esophageal perforation was frequently observed. Patients with uterine and liver cancer were at a higher risk of developing gastrointestinal perforation; patients with liver cancer experienced a shorter onset time, whereas patients with endometrial cancer had a slower onset time. Middle‐aged and elderly patients exhibited a higher propensity for developing gastrointestinal perforation than younger adults. Patients with gastrointestinal perforation were found to have a significantly higher mortality rate than patients without gastrointestinal perforation. This study has identified several gastrointestinal perforation events not included in the drug instructions. It has also described the perforation site and clinical characteristics based on various types of cancer. These results could provide valuable insights for developing safer and more effective regulatory strategies concerning the use of lenvatinib.
On the discontinuous solutions of explicit neutral delay differential equations
Authors: Davari Ali , Maleki Mohammad
Published: July 2023

This paper considers explicit neutral delay differential equations (NDDE) with piecewise continuous initial functions. We explain how the discontinuities in the solutions arise and present a perturbing scheme, in combination with an adaptive Legendre–Gauss–Radau collocation method, to deal with this type of problems computationally. The pointwise and mean convergence of the continuous solution of the perturbed NDDE to the discontinuous solution of the original NDDE are proved. Our new method for discontinuous NDDEs and the rigorous theoretical analysis provided are particularly important since explicit NDDEs have received little attention in the literature. Numerical results are given to show that the proposed method can be implemented in an efficient and accurate manner.
Albedo measurements and energy yield estimation uncertainty for bifacial photovoltaic systems

Published: July 2023

The deployment of bifacial photovoltaic (PV) modules for utility‐scale PV plants has quickly proliferated in recent years. As they can harness the irradiance received at the rear side of bifacial generators—which depends on the albedo of the reflector ground—bifacial modules provide higher productivity than monofacial modules, in exchange for a low increase in manufacturing costs. However, the reduction of PV performance estimations uncertainty still represents a main concern for both PV and financial actors, which seek to reduce financial risks of bifacial PV systems. The aim of this work is to provide a better understanding of the impact that albedo measurements have on PV yield estimations uncertainty. We analysed the albedo sensitivity coefficient relating albedo measurement and subsequent energy yield estimations' uncertainties through a representative yield simulation exercise performed for three different sites (Chile, Spain and Sweden) and two types of PV plants: static and single‐axis tracker. A formula considering the impact of Ground Coverage Ratio and Inverter Loading Ratio is proposed for this coefficient. We performed an experimental campaign to evaluate the uncertainty associated to different albedo measurement conditions. Surface reflectance of five different ground surfaces has been measured using four sensors, which allowed to obtain three useful types of albedos that we defined and described. A series of recommendations for short‐term ground‐based albedo measurements that entail a maximum of 1.5% yield uncertainty contribution in the frame of commercial PV plants are then derived. A representative case of actual albedo measurement practices at the current PV market scene is also presented in the form of a commercial albedo measurement project for a future 50 MW bifacial PV plant. Despite being a local characteristic, the most relevant uncertainty source found is associated to the non‐homogeneity of the future PV plant's surface. An important consideration is that changes in the use of land caused by the construction of a PV plant lead to an albedo uncertainty that predominates over all the uncertainty sources associated to the albedo measurement conditions. This can also be the case for long‐term seasonal variations, which can become the dominant uncertainty source for high latitude locations.

Cadmium sulfide (CdS) is a photocatalyst widely used for efficient H2 production under visible light irradiation, due to its narrow bandgap and suitable conduction band position. However, the fast recombination of carriers results in their low utilization. In order to improve photocatalytic hydrogen production, it reports the successful introduction of metallic Cd and S vacancies on CdS nanorods (CdS NRs) by a facile in situ chemical reduction method, using a thermal treatment process. This procedure generates interfacial and polarization electric fields, that significantly improve the photocatalytic hydrogen production performance of CdS NRs in sodium sulfide and sodium sulfite aqueous solutions, under visible light irradiation (λ >420 nm). The introduction of these electric fields is believed to improve charge separation and facilitate faster interfacial charge migration, resulting in a significantly optimized catalyst, with a photocatalytic hydrogen evolution rate of up to 10.6 mmol−1 g−1 h−1 with apparent quantum efficiency (AQE) of 12.1% (420 nm), which is 8.5 times higher than that of CdS. This work provides a useful method to introduce metallic and S vacancies on metal sulfide photocatalysts to build local polarization and interfacial electric fields for high‐performance photocatalytic H2 production.

Wildfires naturally occur in many landscapes, however they are undergoing rapid regime shifts. Despite the emphasis in the literature on the most severe hydrological responses to wildfire, there remains a knowledge gap on the thresholds of wildfire (i.e., burned area/drainage area ratio, BAR) required to initiate hydrological responses. We investigated hydrological changes in the Russian River Watershed (RRW) in California, a coastal, Mediterranean, drought‐prone, wildfire‐adapted ecosystem, following ten wildfires that burned 30% of the watershed. Our findings suggest that sub‐watersheds of the RRW have not burned beyond an intrinsic, unknown, threshold required to initiate change. Using paired watersheds, we examined spatiotemporal patterns of pre‐and‐post wildfire hydrology with a rainfall‐runoff hydrological model. Even though these successive wildfires burned 1%–50% of each sub‐watershed (1%–30% at moderate/high severity), we found little evidence of wildfire‐related shifts in hydrology. As a function of BAR, wildfire imposed limited effects on runoff ratios (runoff/precipitation) and runoff residuals (observations—model simulations). Our findings that post‐wildfire runoff enhancements asymptote beyond 30% burn indicate that when a watershed is burned beyond a certain threshold, the magnitude of the hydrologic response no longer increases. Drought and storm conditions explained much of the variability observed in streamflow, whereas wildfire explained only moderate variability in streamflow even when wildfire accounted for >45% BAR. While the BAR in the RRW was sufficiently beyond previously reported minimum disturbance thresholds (>20% burned forest), the lack of hydrological response is attributed to buffering effects of wildfire adaptation and drought factors that are unique to Mediterranean ecoregions.

To explore the association between serum lipids and the occurrence and development of endometriosis using a retrospective review of clinical data. A total of 177 patients who underwent laparoscopic or open surgery due to benign ovarian masses, 117 patients with endometriosis (53 stage III and 64 stage IV), and 60 patients with benign ovarian masses without endometriosis were selected from the gynecology department of Maternal and Child Health Hospital of Hubei Province, between January 1, 2020, and October 30, 2022, to search for endometriosis occurrence by retrospectively analyzed the patients clinical data Risk factors for development and to explore the relationship between blood lipids and endometriosis. The scores of estradiol (E2), carbohydrate antigen 125 (CA125), and pain in the endo - and non-endometriosis groups were significantly different (P < .05), but there was no significant correlation between these 3. There were significant differences (P < .05) in E2, triglyceride (TG), CA125, and the size of the masses between patients with stage III and IV endometriosis. TG, E2, and CA125 were found to be valuable as separate indicators for the prediction of endometriosis, and the 3 indicators could improve the accuracy of the diagnosis of endometriosis when combined. Triglycerides may be positively correlated with the severity of endometriosis. The combination of TG, E2 and CA125 can improve the accuracy of the diagnosis of endometriosis staging.
