Analytical approaches to determine the long-term settlement of shallow foundations subjected to dynamic cyclic loading with a large number of cycles (millions) are presented. The approaches use the high-cycle accumulation (HCA) model to calculate the permanent strain caused by the cyclic loading and are conceptionally similar to conventional settlement analyses. The incorporation of a threshold strain amplitude, below which no accumulation of deformations occurs, in the HCA model is discussed. It is demonstrated that the simple analytical approach, which does not require numerical calculations, gives results very similar to more complex finite-element simulations.

Agile approaches enable fast exploration of the context of the problem that has to be tackled, by multidisciplinary teams, with focus on creating empathy and quickly experimenting with new and yet unexplored possibilities.These approaches are currently the most appropriate solutions for the creation and diffusion of innovations with focus on solving complex problems experienced in increasingly digitally connected contexts.This critical systematization text presents the different fundaments related with the main agile approaches that have diffused during the last 20 years, including Roadmapping, Design Thinking and Lean Startup, researched, practiced, reflected and reported in the different initiatives conducted by the author throughout his academic career.Conceptualization and practice of these approaches have revolutionized the traditional approaches of product development and organizational management and can be increasingly incorporated, consolidated and practiced in the different manifestations of the Production Engineering bodies of knowledge.

Este estudo tem como objetivo analisar os níveis de perda alimentar de grupos específicos de alimentos destinados ao suprimento alimentar nacional, confrontando tal problemática com a performance logística do Brasil. Além disso, o estudo se propõe a conduzir uma discussão acerca da problemática nacional e mundial que permeia a questão do desperdício alimentar e suas implicações econômicas, sociais e ambientais. Para tanto, a investigação considerou dados anuais disponibilizados pela FAO referentes ao suprimento doméstico e às perdas de alimentos de 7 grupos específicos de alimentos. Também foram considerados os dados disponibilizados pelo Banco Mundial referente à avaliação do LPI (Logistics Performance Index) e suas 6 dimensões. Os resultados sugerem que a avaliação da performance logística do Brasil apresenta melhorias, principalmente na dimensão “Monitoramento e rastreio”. No geral, a performance logística do país é mediana. O estudo sugere também que os maiores níveis de perda de alimentos em relação ao suprimento são as perdas de frutas, seguido de perdas de cereais, vegetais e raízes. A discussão apresentada enfatiza a problemática do desperdício alimentar e suas implicações na promoção da segurança alimentar e objetivos do desenvolvimento sustentável.

This study aims to verify the effect of implementing a lean manufacturing (LM) system on operational performance in an industrial company’s production line. There are few studies that seek to quantitatively verify the effect of implementing an LM system on the operational performance of a company, and that is the main objective of this research. In this case-based study, the LM implementation in the company studied is compared with best practices and reference models, ascertaining the degree of adherence of the company’s program. The operational performance, in terms of three key dimensions of cost, quality and lead time, is compared before and after the implementation of the LM program. By comparing the means of quantitative indicators related to the three performance dimensions, evidence was found of significant gains in the operational performance, and it was demonstrated that the company followed many of the best practices of LM implementation found in the literature. This study contributes to managers and to the literature on LM by measuring its apparent impacts on operational performance.Key words: Operational performance. Value chain. Lean manufacturing. Best practices.

Human biomonitoring (HBM) programs have been established in several countries around the world in order to monitor the levels of chemical exposures in the general population and qualify health risk assessment of national and international interest. Study design, population, sample collection, and chemical analysis must be considered when comparing and interpreting the results. In this review, the objectives and brief descriptions of the major national HBM programs in North America, Europe, and Asia are provided. Similarities and differences observed from a comparative analysis among these programs, including the stratification of data according to age, sex, socioeconomic background, etc. as well as the identification of chemical exposure associated with food intake, are discussed. Overall, although there are some discrepancies in the study designs among the reviewed national HBM programs, results from the programs can provide useful information such as chemical levels found within the general population of a country that can be compared. Furthermore, the results can be used by regulatory authorities or the government to enforce legislations in order to reduce the exposure of chemicals into the human body.

O objetivo desta pesquisa é mostrar a aplicação da metodologia Planejamento de Experimentos (DOE), no estudo das propriedades mecânicas do arame de aço SAE 9254 trefilado, com diâmetro de 6,50mm, e submetido ao processo de têmpera e revenimento. Por meio deste estudo, foram investigadas as variáveis de entrada do processo e as suas influências buscando projetar um modelo estatístico que permitisse prever os resultados do limite de resistência à tração. Os resultados revelaram que todos os fatores estudados foram considerados influentes, no processo, e o modelo obtido foi validado, utilizando-se Análise de Variância (ANOVA). A Regressão Linear Múltipla permitiu representar o processo adequadamente, e a análise gráfica possibilitou visualizar o comportamento da resposta. As predições realizadas através da utilização do modelo poderão gerar grande impacto, na redução de custos, neste ambiente industrial, tais como: de insumos necessários para a criação de padrões de setup para o tratamento térmico de têmpera, de paradas de processo, de testes laboratoriais e de horas de trabalho de pessoal envolvido nos ensaios laboratoriais.

Intentaremos abordar el problema de la memoria como memoria de las voces en la poesía de Paul Celan, haciendo hincapié en algunos puntos clave de su poesía, como la fecha, el interlocutor providencial, la intertextualidad.
