Facility Management using digital Obeya Room by integrating BIM-Lean approaches – an empirical study

This paper applies a methodology for interdisciplinary Facilities Management (FM) by alingment between Building Information Modeling (BIM) and Lean. Initially, the literature review of BIM, FM and Lean principles. Afterwards, the research applies the Digital Obeya Room for improved FM and describes its application on a real-world case study. Lastly, the work presents a survey with specialists to assess the relevance of each BIM-Lean concepts and correlate their perceptions with the empirical results. The main collaborations of this work are: a conceptual framework that relates the PDCA (Plan-Do-Check-Act) cycle with BIM-Lean approaches; the identification of the most relevant BIM functionalies and Lean principles; and the real-world application of the framework procedures on FM

Efeito da omissão de N, NI, Mo, Co e S sobre os teores de N e S em feijoeiro

Foi avaliado o efeito da omissão de N, Ni, Mo, Co e S sobre os teores de N e S em feijoeiros (Phaseolus vulgaris ) inoculados e não inoculados com Rhizobium, em casa de vegetação. O experimento foi realizado em um esquema fatorial com dois tipos de solo (Neossolo Flúvico), dois níveis de inoculação (com e sem), combinados com seis adubações: (a) Completo (N, P, K, Ni, Mo, Co e S); (b) sem N; (c) sem Ni; (d) sem Co; (e) sem Mo; (f) sem S. O delineamento experimental foi inteiramente casualizado com três repetições. Foram fornecidos 126 mg kg-1 de N (parcelados no plantio, aos 10 e 25 dias da emergência - DAE), 248 mg kg-1 de P, 117 de K e 48 de S, aplicados no solo, e 10, 250 e 10 mg L-1 de Ni, Mo e Co, respectivamente, aplicados via foliar aos nove DAE. A colheita foi efetuada aos 35 DAE, separando-se a folha indicadora das demais. A adubação nitrogenada aumentou o crescimento das plantas, indicando serem os solos deficientes em N, bem como reduziu os teores foliares de N e S. A omissão dos demais nutrientes não alterou o crescimento das plantas nem o teor de N foliar, mas a omissão de S reduziu, como esperado, o teor de S foliar

Mineralogical investigation of several

Context. To take advantage of the large dataset provided by the SDSS data, recently a new taxonomic scheme was proposed designed to be compatible with previous taxonomies. One interesting feature in this distribution is the large number of Qp asteroids scattered all around the main belt with a marked concentration in the Vesta region, where the Vp are found most frequently. Since the mineralogy and thermal evolution traditionally related to the classical Q- and V-type taxonomic classes (and by construction the Qp and Vp), this finding was quite surprising. Aims. We aim to observationally determine the mineralogy of a sample of Qp asteroids of and outside the Vesta family to test whether the Qp of the Vesta family are indeed basaltic, and whether the difference in band depth implied by the SDSS spectra relates to diffences in mineralogy with respect to the Vp. Moreover, we aim to determine whether the Qp outside Vesta family have an ordinary chondrite (OC) mineralogy and whether their spectra indeed correspond to Q-class asteroids. Methods. We observed a sample of asteroids classified as Qp-type in the literature, mainly located in the Vesta family and neighborhood, to confirm their mineralogy. Spectroscopic observations of 11 asteroids were obtained at the SOAR and IRTF telescopes in the visible and near-infrared region. Thermal observations of three objects were also carried out at the Gemini South telescope in order to determine the albedo of the asteroids. Results. The analysis indicated that all observed asteroids in the Vesta vicinity have a basalt-rich mineralogy, with no clear difference from other Vesta family members in terms of silicate composition. From our study it is not clear why these particular basaltic asteroids have a relatively suppressed band I so that they are classified as Qp. Two asteroids with an OC-compatible mineralogy were identified in the external part of the main belt, at around 2.8−2.9 AU. This discovery suggests new dynamical routes for the transport of Q-type asteroids to the near-Earth region and of OC meteorites to the Earth
