In this study, we investigate the structural stability and magnetic properties of Fe − Pd-based ternary alloys. First-principles calculations are employed to analyze the stability of the Z 3-Fe 2 Pd 6 structure with In substitution and to evaluate the magnetic anisotropy energy (MAE) of Z 3-Fe 2 Pd 5 In 1 . This structural modification is attributed to the unique inter-element miscibility of In with Pd and its immiscibility with Fe, which stabilizes the Z 3 phase. Furthermore, the enhanced magnetic coercivity observed in Z 3-Fe 2 Pd 5 In 1 compared to the L 1 2 -FePd 3 phase highlights the potential of controlling atomic ordering and inter-element interactions to design novel functional materials. Our findings also demonstrate that the magnetic anisotropy energy is highly sensitive to the lattice parameters. While the ideal structure exhibits in-plane anisotropy, a small compressive strain on the a -axis can induce a switch to uniaxial anisotropy, providing a plausible explanation for the experimentally observed coercivity. These insights provide a deeper understanding of the relationship between atomic-scale structural changes and macroscopic magnetic properties, offering valuable guidelines for the development of advanced magnetic materials. • First-principles calculations reveal Z 3 phase stability in Fe-Pd-In alloys. • Inter-element miscibility is key to stabilizing the Z 3-Fe 2 Pd 5 X structure. • Magnetic anisotropy is highly sensitive to lattice strain in Z 3-Fe-Pd-In. • Strain can switch magnetic anisotropy from in-plane to uniaxial. • Theory explains coercivity in both In (high) and Pb (low) doped systems.

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants that have been used for various purposes. Although PFAS can pollute the environment in a variety of areas related to the use, storage, and disposal of their products, there are insufficient data on the extent of PFAS pollution outside industrialized countries with their manufacturing facilities. Most of the analyses depend on high-cost liquid chromatography-tandem mass spectrometry. In this study, we established a method to analyze ionic PFAS using gas chromatography-electron impact ionization-mass spectrometry with in-port arylation by diaryl iodonium. Extraction of PFAS from water samples was performed using solid phase extraction with reverse phase sorbent. Fourteen PFAS compounds could be detected from spiked water samples, and the detection limit ranged from 3.1 to 8.1ng L-1. Using this method, we analyzed groundwater samples from Okinawa Island, Japan, and detected PFAS up to a total concentration of 1900ng L-1. This method uses relatively inexpensive analytical equipment; hence, it can possibly enable surveys on PFAS contaminations in a wide range of regions and opportunities.

Fourteen PFAS compounds could be detected from spiked water samples, and the detection limit ranged from 3.1 to 8.1 ng L− 1. Using this method, we analyzed groundwater samples from Okinawa Island, Japan, and detected PFASs up to a total concentration of 1.9 µg L− 1. This method uses relatively inexpensive analytical equipment, hence it can possibly enable surveys on PFAS contaminations in a wide range of regions and opportunities.

Amyloid resistance is the inability or the reduced susceptibility of an organism to develop amyloidosis. In this study we have analysed the molecular basis of the resistance to systemic AApoAII amyloidosis, which arises from the formation of amyloid fibrils from apolipoprotein A-II (ApoA-II). The disease affects humans and animals, including SAMR1C mice that express the C allele of ApoA-II protein, whereas other mouse strains are resistant to development of amyloidosis due to the expression of other ApoA-II alleles, such as ApoA-IIF. Using cryo-electron microscopy, molecular dynamics simulations and other methods, we have determined the structures of pathogenic AApoAII amyloid fibrils from SAMR1C mice and analysed the structural effects of ApoA-IIF-specific mutational changes. Our data show that these changes render ApoA-IIF incompatible with the specific fibril morphologies, with which ApoA-II protein can become pathogenic in vivo.

4 A telenfermagem, é uma abordagem nova e recém regulamentada no Brasil pelo Conselho Federal de Enfermagem (COFEN), na Resolução 696/2022. É uma forma de proporcionar um atendimento efetivo e resolutivo para o paciente a distância com variadas vantagens. Sendo assim, faz-se necessário relatar à alunos da graduação sobre esse assunto para o seu melhor entendimento às práticas inovadas na enfermagem. OBJETIVO: Descrever o uso da telenfermagem no monitoramento a saúde. MÉTODO: Trata-se de um estudo descritivo, do tipo relato de experiência. A pesquisa foi realizada no período de outubro de 2021 a março de 2023, por meio de um estágio extracurricular vivenciado por uma acadêmica de enfermagem. A estratégia utilizada foi o acompanhamento dos pacientes via contato telefônico para realização de educação em saúde, monitoramento, consultoria e acolhimento de demandas espontâneas. RESULTADOS: As consultas eram registradas nas planilhas do Microsoft Excel, compartilhado do setor e o registro de enfermagem realizado no sistema interno da instituição de saúde, destacando mudanças repentinas ou postergadas na saúde do paciente avaliado, resultados de exames, intervenções resultantes positivamente ou negativamente. DISCUSSÃO: Percebe-se que em decorrência da diversidade das Tecnologias da Informação e Comunicação (TICs) utilizadas na telenfermagem, torna-se necessário a compreensão do processo de comunicação neste contexto para subsidiar evidências e aprimorar o cuidado prestado aos pacientes. Sendo assim, é possível observar que a telenfermagem no atual contexto de saúde tornou-se uma prática fortalecida, principalmente durante a pandemia. CONCLUSÃO: Com base nos resultados da pesquisa, pode-se reforçar a relevância da telenfermagem, pois este proporciona favorecimento do vínculo das relações de confiança e a sensação de proximidade, integração, proteção e segurança para expressar necessidades, expectativas e sentimentos na relação profissional e paciente.

Promoting the values of nature among the public is of great importance in order to gain the support for policies to protect the nature. However, a person's support for some policy and other social behaviors may not be derived by referring only to his or her own values, but also to the values of the majority of society as assumed by that person. The questionnaire survey utilized in this study revealed the existence of bias in the personal estimation of others as related to nature conservation, which resembled the above-or below-average effect that is commonly found in estimations of personality and abilities of oneself and others. The preferences that others hold for nature was estimated to be lower than one's own preference, whereas the preference of others in terms of wealth was estimated to be higher. The policies related to the values with positive bias in estimating the preferences of others were judged to be more important when the benefits of others were considered than when only one's own benefits were considered, and the policies related to the values with negative bias were judged to be opposite. It is suggested that such bias in estimating the preferences of others can be affecting how the public supports the policies concerning nature conservation and economic development.
