Dentre todos os processos logísticos, o recebimento e a armazenagem se destacam como os de maior importância, pois são o ponto de partida para os demais processos e os erros provenientes dos mesmos refletem diretamente na entrega ao cliente. Porém a responsabilidade de gerir a operação de outra empresa é muito grande e os custos envolvidos são altíssimos caso os problemas comecem a surgir nessas operações. O objetivo do trabalho foi analisar os processos de recebimento e armazenagem de mercadorias em um operador logístico. A análise desses processos se fez necessária em razão dos problemas que a empresa objeto de estudo tem enfrentado devido às devoluções provenientes de erros nesses processos. No percurso metodológico foi utilizada a abordagem qualitativa, de caráter exploratório utilizando-se também da pesquisa de campo. Após a observação direta dos processos e entrevistas com os envolvidos nos mesmos, foi feita uma discussão dos resultados, tendo como base principal a comparação teoria/prática. A pesquisa apontou falhas no processo de recebimento, mau aproveitamento do espaço do armazém, equipamentos inadequados, falta de identificação de áreas entre outras. Foi elaborado um quadro contendo as principais falhas bem como as ações de melhorias propostas para que as mesmas não continuem acontecer.

Um almoxarifado bem estruturado é fundamental para a sustentabilidade dos demais processos dentro de uma empresa. Todas as áreas necessitam diretamente ou indiretamente da atuação logística para entregar, receber e movimentar produtos desde o transporte de insumos até a entrega no cliente. O almoxarifado vai muito além do que receber, entregar e armazenar itens do estoque, este setor requer um controle preciso, visto que é nele que fica armazenada parte dos recursos materiais da empresa. Objetivou-se analisar os procedimentos de recebimento de mercadoria e sugestão de melhorias para otimização dos processos logísticos em uma indústria de cosméticos S.A. A metodologia utilizada em relação à natureza foi exploratória e quanto aos procedimentos adotados na pesquisa foi realizado entrevistas com os responsáveis de cada operação, salientando-se que as melhorias identificadas foram aplicadas durante o andamento do estudo realizado. Os resultados obtidos proporcionaram análise dos procedimentos e sugestões para melhorias, tais como: a falta de espaço, ausência de equipamento de movimentação, falta de sinal de rede para os coletores via ERP, controle e gestão de planejamento de produção, devido esses impasses tem sido um dos grandes responsáveis pelo aumento do preço final do produto acabado.

Background:Axial Spondyloarthritis (axSpA) refers to a group of rheumatic diseases that mainly affect the axial skeleton. Treatment with Biological Disease Modifying Anti-Rheumatic Drug (bDMARDs) is indicated when low disease activity is not achieved with Non-Steroid Anti-inflammatory Drugs. Some studies reported that some clinical and socio-demographic were associated with biologics initiation1,2. However, early factors associated with the initiation of bDMARDs have not been extensively studied.The authors speculate that certain features early in disease presentation may be associated with future need for treatment with bDMARDs in patients with axSpA.Objectives:To study a population of patients with axSpA and determine whether the presence of certain factors at diagnosis is associated with a later need for biological treatment.Methods:A single centre retrospective study was conducted comprising patients fulfilling the ASAS criteria for axSpA that attended the Rheumatology Outpatient Clinic from January to December 2019. Patients with psoriatic arthritis and enteropathic spondyloarthritis were excluded. All data, except regarding use of bDMARD, refers to the two initial appointments. Between group comparisons were performed through independent sample t-test or Chi-Square as applicable. Logistic Multivariate Regression was performed to understand which factors independently contributed to the use of bDMARDs.Results:One hundred and fifty patients were included, and 52 patients (34,7%) were under biological treatment. In comparison to the group that was not under treatment with bDMARDs, these were significantly more likely to be hard-workers (57,8% vs 29,7%; p =,003), to have had elevated C-Reactive Protein (81,6% vs 48,9%; p vs 29,5%; p vs 13,3%; p =,006). No differences between groups were found in sex, age, HLA-B27 positivity, state of employment, diagnostic delay, smoking status, history of dactylitis and history of uveitis. In multivariate regression analysis, only the hard-worker type and the highest grade of sacroiliitis were found to be independently associated with the use of bDMARDs as presented in Table 1. Although not statistically significant, a trend to association was found between elevated CRP at diagnosis and use of bDMARDs.Table 1.Multivariate logistic regression of variables associated with initiation of bDMARDs.BS.E.WaldOR95% CIpWorker typeaNon-hardref.Hard1,127,5094,8903.09 1.14 – 8.37.027*HLA-B27Negativeref.Positive1,153,6702,9623.17 0.85 – 11.77.085CRPaNormalref.Elevated1,003,5293,5912.730.97 – 7.69.058Grade of Sacroiliitisa≤2ref.>21,485,4899,2264.411.69 – 11.50.002*History of EnthesitisaNoref.Yes,299,574,2721.35 0.44 – 4.15.602aAt the time of diagnosis; ref. - referenceS.E. – Standard Error; OR – Odds Ratio; CI – Confidence IntervalConclusion:In our study, the performance of work associated with greater biomechanical stress and the presence of greater structural damage at diagnosis were shown to be associated with the latter use of bDMARDs. The authors highlight the importance of recognizing these factors that seem to relate to more aggressive disease, with more structural damage, thus suggesting a need for a tighter control management strategy in these patients accordingly current guidelines. More studies still needed to better depict the influence of certain early clinical and patient related variables in management of axSpA patients.References:[1]Png WY, Kwan YH, Lee YX, et al.

One of the main objectives of seismic imaging is to generate maps of the Earth's reflectivity function, which can be inferred about the physical properties of rocks in their locations. The amount of energy that is reflected on an interface depends on the incident’s wave field angle, called AVA (Amplitude vs. Angle) function. In the methodology proposed in this work, the seismic data recorded on the surface is extrapolated to a region just above the datum of the exploratory interest. This redatum is achieved by a generalization of the concept of reverse time migration in which common focus point gathers are extrapolated. The synthesis’ operators and extrapolations of the direct and reverse fields are made for solutions of acoustic complete wave equation by finite differences method. It was proposed a new imaging condition based on the sum of modules of amplitudes around the wavelet of maximum amplitude. As a result of this methodology, we have obtained graphs of reflectivity, i.e., amplitude based on incidence’s angle, corrected from effects of propagation (specifically, spherical divergence, transmission and conversion).

This work aims to analyze the capacity of the conventional Reverse Time Migration related to structures imaging in complex geological models such as below salt bodies, which is one of the greatest challenges in the petroleum exploration. The velocity model used was a slice of the 3D SEG/EAGE salt dome, known as Salt-BB. Acoustic modeling was used to generate 2D seismic data. In order to enrich the study, this acoustic modeling was performed with the variation of two very important seismic data acquisition parameters: shot point interval and receiver interval. A technique for removing artifacts from migrated data, known as selective mute, was implemented to improve the outcome of the stacked section.

This work presents a comparative study of different image conditions applied to reverse time migration (RTM) of seismic data. The study aims to evaluate the obtained migrated section with each image condition. The finite difference method was used to discretize the complete wave equation in bidimensional acoustic modeling with fourth order spatial approximation and second order time approximation. In this work were studied three velocity models to evaluate different degrees of geological complexity. A SEG/EAGE’s model with salt layer was considered because of the importance of pre-salt regions to Brazilian petroleum industry. In this work it was carried out pre-stack migration where each seismogram is individually migrated. A data filtering technique called mute was used to improve the stacked migrated section. Introducao

The angle dependent refletivity of a reservoir target is a crucial input for reservoir characterization. A prestack depth migration should be able to produce not o accurate structural image, but also reliable angle dependent information. The propose of this work is to present the results of an investigation about how different wave equation implementations can influence the migrated section amplitudes obtained by Reverse Time Migration (RTM). Especially for true-amplitude wave equation migration algorithms, a stable schedule is essential to recover the medium reflectivity successfully. To obtain accurate image amplitudes needed to apply amplitude versus angle analysis (AVA) receiver extrapolations must be able to accurately reconstruct their respective wavefields at the target reflector.

O presente trabalho aborda a utilizacao da tecnica de Registro de Multiplas Fontes no imageamento de estruturas geologicamente complexas. Esta e uma tecnica de empilhamento de familias de tiro comum, cujo dado empilhado e equivalente aquele que seria obtido na aquisicao de uma detonacao de multiplas fontes, simultaneamente ou com atrasos entre os tiros, gerando um unico dado, o chamado supersismograma. Foi utilizado para testes, numa modelagem numerica acustica, o modelo sintetico de velocidade MARMOUSI. As secoes migradas foram obtidas atraves dos metodos RTM e PSPI. No intuito de focalizar as areas de interesse exploratorio, utilizou-se tambem o metodo de Migracao Orientada ao Alvo numa abordagem um pouco diferente da proposta pioneiramente. No presente trabalho um tiro simulado e dado acima do alvo e registrado na superficie, de onde se retiram os atrasos da chegada da onda direta. Estes sao utilizados na detonacao das multiplas fontes, formando acima deste alvo uma frente de onda plana. Resultados promissores foram encontrados, principalmente em relacao ao imageamento em regioes abaixo de camadas que apresentam altos contrastes de impedância, demonstrando que a tecnica apresenta-se uma alternativa viavel a migracao pre-empilhamento convencional.

Seismic imaging of hydrocarbon accumulations under structures with high acoustic impedance, such as saline and basaltic structures, has been of one the targets in the oil industry as a consequence of recent discoveries of interesting petroleum systems in structures like that. Signal-noise ratios of the seismic sections under those structures are usually lower than the one necessary for reliable interpretations. In this work, we study two seismic depth migration techniques, Reverse Time Migration (RTM) and Phase Shift Plus Interpolation (PSPI) of Areal Shot Records, in order to compare their performance on numerical seismic data generated on geological models which present exploration objectives located under high acoustic impedance layers. On our experiments, except for some small artifacts, the results produced by both techniques after depth migrating just one areal shot, almost do not differ and were excellent. It was possible to identify the main interfaces with confidence.
