Authors: Aboubacar YERIMA BAKO DJIBO , Salifou ILLA , YAHAYA Abdou
Published: January 2025

Niger is a Sahelian country located in West Africa, characterized by unfavorable climatic conditions, with low rainfall and continuous degradation. The combination of all these phenomena it is in this context that this study was carried out in the Aneker area. The study objective is therefore to make an exhaustive diagnosis of the irrigation and drainage networks. The methods adopted includes the study of hydraulic works of irrigation and drainage canals of the study area and supplement with interview of the stakeholders in irrigation, National Hydro-Agricultural Office (ONAHA) Technicians and those responsible for irrigation water management. The study reveals that 68% of the plots lack sufficient irrigation water. Remove the highlighted and replace with above sentence. Also, the results indicated that 91 % of irrigation farmers abandoned their plots of land due to lack of water from the severe degraded state of the irrigation water distribution channels. The 37% severely degraded state of the irrigation network leads to a huge loss in the transport of water to the plots. Consequently non-compliance with the water flow, the irrigation farmers are no longer able to have the water supply required to satisfy water needs. Which requires a longer irrigation time beyond 12 hours. So that the Aneker perimeter can be operational in an effective and sustainable manner, it would be interesting to rehabilitate all that remains of the hydraulic works. The limit of this research of irrigators in the maintenance of these infrastructures and in water management.

Zur Bedeutung der Gewährung rechtlichen Gehörs – „audiatur et altera pars“ als Grundpfeiler des Rechtsstaats im Zivilprozess
Authors: Groteclaes Anna Leoni
Published: January 2025

Die rechtsstaatliche Verfahrensgarantie der Gewährung rechtlichen Gehörs i.S.d. Art. 103 Abs. 1 GG ist das konstitutive Merkmal aller gerichtlichen Verfahren und unabdingbar für das Vertrauen des Bürgers in die staatliche Rechtsprechung. Dennoch existieren im Zivilprozessrecht bis heute - trotz der unbestrittenen rechtsstaatlichen Bedeutung des Anspruchs auf Gewährung rechtlichen Gehörs - offene Fragen, wenn es um die effektive verfassungsrechtliche Imprägnierung des Verfahrensrechts und die dogmatische Konturierung dieses elementaren Grundsatzes geht. Diese Fragen zu umreißen und dabei die ideengeschichtliche Tradition der Gehörsgewährung aufzuzeigen, ist Gegenstand des nachfolgenden Beitrags.

Published: July 2023

The description of a solid at a microscopic level is complex, involving the interaction of a huge number of its constituents, such as ions or electrons. The Hubbard model used in this research describes interacting electrons in narrow energy bands, with application to problems as diverse as high – Tc superconductivity, band magnetism and the metal-insulator transition. This research seeks to solve one of the most challenging problems in Theoretical physics which is to describe electronic correlations. In this research the t – U Hubbard model is used to solve analytically and numerically using the exact diagonalization techniquesThis research work focused on the spin interaction and magnetic behavior of some systems and it is therefore an investigation into the various phenomena seen in the phase diagram of ferromagnetic systems. We studied the 2 electrons on 2 sites, 2 electrons on 3 sites and 2 electrons on 4 sites all in One-Dimension (1-D), where the onsite coulomb repulsion, U, and the hopping matrix element, t, were varies to determine their magnetic phase diagram.This results obtained shows that, as the values of the onsite coulomb repulsion, U, increases in all the lattice systems studied, the electronic correlation that favours ferromagnetism gets stronger, but there were no clear transition, and at some point the lattices loss its antiferromagnetic properties, hence the instability of ferromagnetism were established. It was also observed that as the hopping matrix element, t, increases the electronic correlation that favours ferromagnetism get stronger and the lattice begins to loss antiferromagnetic properties but beyond the transition point the lattice began to gain a much stronger antiferromagnetism, hence the ferromagnetism is unstable.

Many parents have few references to send their children to school, and are only based on suggestions or invitations from those closest to them. Lack of information can be one of the reasons for the lack of references for parents to choose a junior high school for their child. The lack of information regarding the location of junior high schools is the reason for the lack of references for parents to send their children to school. Based on the existing problems, the authors propose a web-based geographic information system that uses the A-Star Algorithm (A*) to be used as a means of information and also to add references for parents/guardians. The A-Star (A*) algorithm is a method for searching for information about the distance to reach a destination by selecting the closest route.

A teoria que Freud construiu com a psicanálise dá conta da incerteza e da multiplicidade do campo clínico; algumas novas articulações, entretanto, apóiam os diversos desenvolvimentos teóricos atuais com maior ou menor convergência com o modelo de Freud. As raízes incontestáveis que fundamentam a psicanálise são o conceito de Inconsciente, a Sexualidade, o Narcisismo, a Teoria das Pulsões e seus destinos, incluindo a pulsão de morte, a repetição, o a posteriori, o modelo do transferível e a Transferência. Festejando 150 anos do nascimento de Freud, algumas indagações são pertinentes: frente às demandas da clínica atual, quais transformações se impõem ao modelo da psicanálise desde Freud?; afinal, de que inconsciente se trata quando a repetição não se apóia nas produções (formas-de-ação) do inconsciente recalcado?; utilizamos hoje os mesmos recursos teóricos-técnicos para abordá-lo?; Em resumo, para sustentar que a metapsicologia freudiana ainda mantém sua vigência, vale indagar-nos que articulações importam para atualizá-la, para ser enriquecida depois de problematizada por uma subjetividade que sofreu profundas transformações.
Dry Sliding Wear Properties of Annealed Carbon Steels Matrix Composites by Nanosized TiC‐TiB2 Particles
Authors: Zhang Yu , Wang Bingxu , Qiu Feng , Dong Baixin , Wu Zhijun , Li Hongjun , Barber Gary C.
Published: July 2023

Herein, nanoparticle‐reinforced carbon steels are innovatively prepared through the use of TiC‐TiB2/Al master alloys. The effects of nanoparticles on the microstructure and wear performance of carbon steels are investigated. It is found that the addition of nanoparticles inhibits the Widmanstatten structure. Also, the nanoparticles promote the formation of pearlite with finer lamellar structure and reduce the grain size. During the liquid–solid and solid–solid phase transformations, the nanoparticles act as heterogeneous cores to improve the nucleation rate. For wear tests, the presence of nanoparticles enhances the wear resistance of carbon steels. Carbon steels with 0.02 wt% nanoparticles show the lowest wear volume loss rate under each test condition. The excellent wear performance is related to the high hardness of substrates, inhibiting dislocation movement due to the refined microstructure and nanoparticles, and withstanding the external loads by nanoparticles. The findings obtained in this work can provide a new approach to fabricate high‐wear‐resistant carbon steels.
Electric‐Dipole Gated Two Terminal Phototransistor for Charge‐Coupled Device

Published: July 2023

The demand for charge‐coupled device (CCD) imagers has surged exponentially during the last decade owing to their exceptionally high quality and low noise imaging. However, they are still confronting the performance constraints of high operation power, low speed, and limited charge integration. Here, the electric‐dipole gated phototransistor operation without external gate bias is reported by using high‐k HfO2 dielectric material. The electrostatic coupling of photogenerated charges from the Si with the graphene channel through a 10 nm HfO2 layer is demonstrated. The device exhibits remarkable performance in the broadband spectrum (266–1342 nm) at low drain bias voltage. The high values of responsivity, external quantum efficiency, and detectivity of 3.7 × 103 A W−1, 0.72 × 104, and 6.20 × 1013 cmHz½ W−1, respectively, for 800 nm wavelength and 3.3 × 103 A W−1, 1.31 × 104, and 5.61 × 1013 cmHz½ W−1, respectively, for 400 nm wavelength without gate are achieved. This discovery may potentially eliminate the requirement for gate terminals from commercial CCD devices. The power efficient features of this gateless image sensor can be fabricated at the industrial scale for the future machine vision market.
Leveraging Thermal Properties Data toward Efficient Photothermal Therapy of Mammary Glands

Published: July 2023

Photothermal therapy (PTT) is gaining wide attention in oncological applications. Nevertheless, its efficacy is still being questioned due to the potential deleterious thermal impact on healthy tissues. The comprehension of tissue thermal properties and their role in photothermal heat transfer is critical. In this study, the thermal conductivity of murine mammary gland (MG) tissues (both tumorous and normal) is initially characterized as a function of time post‐tumor cell inoculation. Notably, the tumorous MGs exhibit a mean thermal conductivity of 0.41 ± 0.013 W m−1 K−1, a 28% increase compared to the normal tissue (0.32 ± 0.003 W m−1 K−1). A self‐developed ultra‐fast hot‐wire technique is employed to assess the marginal temperature elevation in thin MG samples. These experimental findings suggest that the thermal conductivity escalates as the tumor advances. Employing a constant‐power laser, variations in therapeutic outcomes are attributed to the synergistic effect of augmented thermal conductivity and tumoral volume. Importantly, these data substantiate that the early commencement of photothermal irradiation effectively stymies tumor advancement. These insights can foster improved early‐stage PTT by calibrating irradiation schedules contingent on meticulous thermal property assessments, thus optimizing therapeutic results.

In many slowly developing mammal species, males reach sexual maturity well before they develop secondary sexual characteristics. Sexually mature male orangutans have exceptionally long periods of developmental arrest. The two male morphs have been associated with behavioral alternative reproductive tactics, but this interpretation is based on cross‐sectional analyses predominantly of Northwest Sumatran populations. Here we present the first longitudinal analyses of behavioral changes of 10 adult males that have been observed in both unflanged and flanged morph. We also analyzed long‐term behavioral data on an additional 143 individually identified males from two study sites, Suaq (Sumatra, Pongo abelii) and Tuanan (Borneo, Pongo pygmaeus wurmbii), to assess male mating tactics cross‐sectionally in relation to population, male morph (unflanged and flanged), and other socio‐ecological factors. Both our longitudinal and cross‐sectional results confirm and refine previous cross‐sectional accounts of the differences in mating tactics between the unflanged and the flanged male morphs. In the unflanged morph, males exhibit higher sociability, particularly with females, and higher rates of both copulation and sexual coercion than in the flanged morph. Based on our results and those of previous studies showing that females prefer flanged males, and that flanged males have higher reproductive success, we conclude that unflanged males face a trade‐off between avoiding male‐male contest competition and gaining mating access to females, and thus follow a “best‐of‐a‐bad‐job” mating strategy.

Solid‐state electrolytes (SSEs) with high ionic conductivity and superior stability are considered to be a key technology for the safe operation of solid‐state lithium batteries. However, current SSEs are incapable of meeting the requirements for practical solid‐state lithium batteries. Here we report a general strategy for achieving high‐performance SSEs by engineering polymers of intrinsic microporosity (PIMs). Taking advantage of the interconnected ion pathways generated from the ionizable groups, high ionic conductivity (1.06×10−3 S cm−1 at 25 °C) is achieved for the PIMs‐based SSEs. The mechanically strong (50.0 MPa) and non‐flammable SSEs combine the two superiorities of outstanding Li+ conductivity and electrochemical stability, which can restrain the dendrite growth and prevent Li symmetric batteries from short‐circuiting even after more than 2200 h cycling. Benefiting from the rational design of SSEs, PIMs‐based SSEs Li‐metal batteries can achieve good cycling performance and superior feasibility in a series of withstand abuse tests including bending, cutting, and penetration. Moreover, the PIMs‐based SSEs endow high specific capacity (11307 mAh g−1) and long‐term discharge/charge stability (247 cycles) for solid‐state Li−O2 batteries. The PIMs‐based SSEs present a powerful strategy for enabling safe operation of high‐energy solid‐state batteries.

The impact of titanium dioxide (TiO2) on the physical properties of poly(lactic acid) (PLA) is explored, along with the combined effect of Atomic Layer Deposition of zinc oxide (ZnO) on the nanocomposite films' surface. PLA/TiO2 bionanocomposites are prepared via melt‐extrusion and characterized in terms of their morphological, thermal, and mechanical properties. Homogeneous dispersion of the filler offers enhanced mechanical performance for samples up to 5 wt% in TiO2 content. Thermal stability of PLA is also slightly improved upon increasing TiO2 content. This work also demonstrates that surface modification of PLA/TiO2 films employing Atomic Layer Deposition of zinc oxide enhances hydrophobicity, while antimicrobial activity, although mild, appears enhanced for coated samples. Water vapor permeability is retained in both coated and uncoated nanocomposites. Surface characterization of the studied specimens, by x‐ray photoelectron spectroscopy and scanning electron microscopy, reveals subsurface diffusion and reaction of the depositing compounds within PLA, leading to a different surface chemistry involving Zn(OH)2. This study gives valuable insights on the parameters affecting the atomic layer deposition of inorganic coatings on a polymeric substrate in the presence of nanoinclusions and, therefore, on the physical properties of the coated films, providing the pathway for their exploitation in food packaging applications.
Distance versus face‐to‐face education of gross anatomy for dental hygiene students: Perceptions and academic achievements of learners
Authors: Kim Da‐Hye
Published: July 2023

The provision of distance education has increased rapidly over the past few years owing to the COVID‐19 pandemic. The core of gross anatomy distance education is three‐dimensional (3D) visualization of anatomical structures, and the use of simple 3D visualization tools has increased as distance education has become more popular. The purpose of this study was to establish a more effective operation plan in dental hygiene by investigating learners' opinions about distance education of gross anatomy and 3D visualization tools, and by comparing and analyzing their academic achievements. The study involved 250 students and comprised an analysis of 120 students who took a head and neck anatomy class at the Department of Dental Hygiene at D University via distance learning during 2020–2022, and 130 graduates who had completed the class via face‐to‐face learning during 2015–2017. An online survey of 120 of the enrolled students comprised 10 questions asking for opinions on the head and neck anatomy distance learning classes, five questions on the 3D visualization tool, and five on general characteristics. Overall, the learners had positive perceptions of distance education for head and neck anatomy and the 3D visualization tool. Among the education methods compared, they generally preferred blended learning (n = 47, 39.2%). There was a significant preference for the distance learning method of asynchronous classes (n = 86, 94.5%). Analysis of academic achievements according to whether or not distance education was conducted revealed a significantly higher score in the face‐to‐face class group (P < 0.05). A blended learning method can be effective in increasing learner satisfaction and improving academic achievement in gross anatomy classes on dental hygiene. It is suggested that theoretical material should be learned through asynchronous content and knowledge expanded through small‐group activities during face‐to‐face learning. This will help establish a standard model for teaching of gross anatomy in dental hygiene in the postpandemic era.
Relational transformation or resolution only? A quantitative analysis of mediator and disputant behaviors, and mediation outcome
Authors: Tsuruhara Toshiyasu , Cremin Hilary
Published: July 2023

This research quantitatively investigated the behaviors observed in mediation. We coded 16 mediation sessions recorded at a secondary school in the United Kingdom as relational transformation or resolution only and examined if the frequencies of the behaviors were significantly different between these two categories. We also investigated how the characteristics of their behaviors were correlated. Results indicated that the frequencies of the mediator's empathetic and the disputant's open, expansive, and defiant behaviors were significantly different between the two categories. Our findings also suggested several positive correlations between the behaviors, including the disputant's open and expansive, open and the mediator's empathetic, expansive and the mediator's eliciting, and negative between open and the mediator's directive, and defiant and the mediator's eliciting behaviors. Our findings mostly supported what has been widely discussed among the mediation researchers and practitioners—active listening, empathy, and impartiality, but also found a mutually enhancing relationship between the disputant's open and expansive behaviors. For relational transformation, we argue that the mediator should demonstrate empathy to help the disputant's open expression while asking eliciting questions to encourage their mutual acknowledgment and preclude defiance.
Homocysteine metabolites inhibit autophagy, elevate amyloid beta, and induce neuropathy by impairing Phf8/H4K20me1‐dependent epigenetic regulation of mTOR in cystathionine β‐synthase‐deficient mice
Authors: Witucki Łukasz , Jakubowski Hieronim

The loss of cystathionine β‐synthase (CBS), an important homocysteine (Hcy)‐metabolizing enzyme or the loss of PHF8, an important histone demethylase participating in epigenetic regulation, causes severe intellectual disability in humans. Similar neuropathies were also observed in Cbs−/− and Phf8−/− mice. How CBS or PHF8 depletion can cause neuropathy was unknown. To answer this question, we examined a possible interaction between PHF8 and CBS using Cbs−/− mouse and neuroblastoma cell models. We quantified gene expression by RT‐qPCR and western blotting, mTOR‐bound H4K20me1 by chromatin immunoprecipitation (CHIP) assay, and amyloid β (Aβ) by confocal fluorescence microscopy using anti‐Aβ antibody. We found significantly reduced expression of Phf8, increased H4K20me1, increased mTOR expression and phosphorylation, and increased App, both on protein and mRNA levels in brains of Cbs−/− mice versus Cbs+/− sibling controls. Autophagy‐related Becn1, Atg5, and Atg7 were downregulated while p62, Nfl, and Gfap were upregulated on protein and mRNA levels, suggesting reduced autophagy and increased neurodegeneration in Cbs−/− brains. In mouse neuroblastoma N2a or N2a‐APPswe cells, treatments with Hcy‐thiolactone, N‐Hcy‐protein or Hcy, or Cbs gene silencing by RNA interference significantly reduced Phf8 expression and increased total H4K20me1 as well as mTOR promoter‐bound H4K20me1. This led to transcriptional mTOR upregulation, autophagy downregulation, and significantly increased APP and Aβ levels. The Phf8 gene silencing increased Aβ, but not APP, levels. Taken together, our findings identify Phf8 as a regulator of Aβ synthesis and suggest that neuropathy of Cbs deficiency is mediated by Hcy metabolites, which transcriptionally dysregulate the Phf8 → H4K20me1 → mTOR → autophagy pathway thereby increasing Aβ accumulation.
From two sensors to a single sensor: Better understanding of oxygen–sulfide interfaces

Intense biogeochemical transformations in sediments and biofilms may occur over sub‐mm distances. Our current understanding of those transformations in such narrowly stratified environments has been facilitated by the introduction of microsensors. Until now most studies have been conducted using individual sensors for the various chemical species, and careful vertical alignment of the sensor tips is then essential for the meaningful interpretation of the resulting data. For instance, the determination of total dissolved sulfide (TDS) at high resolution requires perfect alignment of sensors for H2S and pH, as the pKa for H2S is close to ambient pH. In this study, we show how a recently developed TDS sensor and a new combined H2S/O2microsensor can improve the analysis of sulfidic environments including the oxygen–sulfide interface. The TDS sensor does not require pH correction unlike the conventional H2S sensor, and it thus eliminates the need for a simultaneous pH measurement. The combined sensor allows for perfect alignment of H2S and O2micro profiles and makes it possible to not only more accurately estimate fluxes, but also to determine overlapping zones of oxygen and dissolved sulfide at very high resolution.
