The Effect of Ce Content on NbC precipitate in S30432 Austenitic Heat-Resistant Steel
Repeated surgical oocyte collection from severe immunodeficient NOG mice after repeated superovulation with inhibin antiserum and eCG.
Repeated surgical oocyte collection in mice enables the harvest of multiple cohorts of eggs from a single female, thereby reducing the need for animal use. Traditionally, oocyte collection for the mouse requires euthanasia, and only two sequential collections have been reported. The most efficient superovulation protocol involves the use of inhibin antiserum; however, repeated administration may pose a risk of anaphylactic reactions. In this study, we used severely immunodeficient NOG mice to evaluate the feasibility of performing three serial oocyte collections with inhibin antiserum treatments. We found that three consecutive cycles of antiserum administration followed by surgical retrieval cycles were achieved without mortality. Although the number of mice from which oocytes could be collected decreased over successive cycles, oocyte retrieval remained feasible. The application of the anti-adhesion film improved the number of mice from which oocytes could be recovered. Furthermore, embryos derived from the third retrieval developed to term after transfer. However, compared with the control group, we were unable to achieve a proportional increase in the number of retrieved oocytes corresponding to the number of collection cycles. Further improvements to this repeated collection method may include increasing the number of consecutive retrievals, optimizing the protocol to enhance both the oocytes yield and the fertilization rates. Such advances could increase oocyte yield per female, enable the mass production of embryos from fewer animals.

Mathematical Modeling of the Global Engineering Process for Optimizing Product Quality in the Aerospace Industry
The aerospace industry faces the challenge of maintaining product excellence amidst intricate processes and demands for cost and time efficiency. Mathematical modeling emerges as a valuable tool for optimizing the engineering process and enhancing quality, with potential applications extending beyond aerospace to other sectors with high quality and safety standards. This study develops and validates a mathematical model specific to the aerospace industry, aiming to assess the impact of human resource expertise on product quality. Through a case study within an aerospace organization, an IDEF0-methodology-based mathematical model, coupled with weighted averages, was constructed to depict the comprehensive engineering process and quantify knowledge’s impact on deliverable quality. Simulation data, gathered through human resource knowledge assessments and non-conformity analyses, revealed a direct correlation between technical knowledge levels and deliverable quality, consequently impacting final product quality. The proposed model serves as a tool for estimating potential deliverable error rates and pinpointing critical areas within the process that necessitate refinement. The research underscores the significance of knowledge investment and effective knowledge management strategies in upholding quality and competitiveness across industries with stringent quality requirements.

O câncer de mama se caracteriza pela proliferação anormal de forma rápida e desordenada das células do tecido mamário. A doença se desenvolve em decorrência de alterações genéticas. Em seu funcionamento normal, o corpo substituiu as células antigas por células novas e saudáveis.Objetivo:Investigar o cenário clínico e epidemiológico da mortalidade por neoplasias de mama entre os anos de 2019 a 2023.Metodologia: Trata-se de um estudo epidemiológico, de caráter descritivo com informações obtidas por meio do Sistema de Internações Hospitalares pelo Departamento de Informática do Sistema Único de Saúde (DATASUS), analisando o cenário epidemiológico da mortalidade por neoplasias de malignas de mama no Brasil, em um recorte temporal de 2019 a 2023, filtrado pela Classificação Internacional de Doenças e Problemas Relacionados à Saúde (CID-10), o código utilizado foi Neoplasias malignas de mama. Foram analisados dados de óbitos por neoplasias malignas de mama, no brasil onde apresentou um quantitativo de 29.820 de óbitos. Resultados e Discussão: Foram analisados dados da mortalidade por neoplasias malignas de mama entre 2019 a 2023 onde foi possível estimar 2,1 milhões de casos novos de câncer e 627 mil óbitos pela doença. O ano de 2022 apresentou o maior índice de óbitos com um número de 6.246, entre as faixas etárias analisadas os maiores índices estão entre 40 a 69 anos com maior percentual entre a raça branca. A região sudeste lidera o ranking com 16.351 óbitos. Conclusão: Compreende-se que alguns fatores podem estar diretamente associado aos elevados números de óbitos por neoplasias malignas de câncer de mama, como faixa etária. É necessário investimento na educação em saúde visando informar a sociedade a importância de cuidado e rastreamento ao câncer de mama, as estratégias de rastreamento irão ajudar a reduzir os casos de neoplasias e atuar na diminuição dos números de óbitos, garantindo assim, diagnóstico de forma precoce.

Improvement of Mechanical Properties by Internal Matrix Reinforcement in Bronze Processed Nb<sub>3</sub>Sn wire
We approached the internal matrix reinforcements using the Cu-Sn-Zn and Cu-Sn-In ternary bronze alloy matrices. After Nb3Sn phase synthesis, these ternary bronze alloy matrices were transformed into(Cu, Zn)or(Cu, In)solid solutions having much higher mechanical strength. Jc degradation due to the transverse compressive stress on the internal matrix reinforced Nb3Sn multifilamentary wire was evaluated. No Jc degradation was observed at approximately 100 and 150 MPa, which values were much higher than the conventional bronze processed Nb3Sn wire. We found that the internal matrix reinforcement was effective for suppressing Jc degradation due to transverse compressive stress.

Climate change is mainly due to increasing concentrations of CO2 and other greenhouse gases. Indonesia has ratified the Kyoto Protocol of 1997 with Undang Undang Nomor 17 Tahun 2004 concerning the Ratification of the Kyoto Protocol To The United Nations Framework Convention On Climate Change. Indonesia is a party of the Kyoto Protocol 1997 and is bound to implement provisions in reducing greenhouse gas emissions in its territory. Based on this phenomenon, the problem in this study is how to regulate greenhouse gas emissions based on the Kyoto Protocol 1997 and how the implementation in Indonesia? The method used in this study is a qualitative method with secondary data sources. The result of this study is to discover the regulation of greenhouse gas emissions according to the Kyoto Protocol 1997 and to determine the implementation of the regulation greenhouse gases based Kyoto Protocol in Indonesia and obstacles towards the implementation.
