    In a highly competitive environment among companies, standardization of processes has been one of the means to reduce errors, defects, and costs. Thus, the objective of this study is to investigate what is the best standard with parameters to be applied to the manufacture of corrugated cardboard in a company in the Industrial Pole of Manaus (PIM), aiming to reduce the number of wastes from this process. The data were collected from the production management system of company X and analyzed through brainstorming with the employees of the studied process. At the end of the research it was concluded that the parameters that most influence the generation of approximately 9 types of scrap are: (a) Temperature of the cover and core; b) Press pressure; c) Corrugate pressure; d) Glue crack; e) Pressure of the coil door brakes. To reduce factory waste, a standardized list was proposed containing the parameters for each composition, observing the peculiarities of this production process

    Dentre os diversos grupos de abelhas, encontramos a tribo Meliponini, cujas espécies são conhecidas popularmente como abelhas indígenas sem ferrão, por possuírem um ferrão vestigial atrofiado. A criação racional dessas abelhas é denominada meliponicultura, termo cunhado em 1953 pelo pesquisador Paulo Nogueira Neto, um dos precursores dos estudos sobre abelhas sem ferrão no Brasil. Esse trabalho teve como objetivo sensibilizar as comunidades circunvizinhas à Universidade Estadual do Maranhão (UEMA) sobre a importância socioambiental das abelhas nativas e seu papel sustentável e geradora de renda complementar aos agricultores. O meliponário, localizado próximo ao Laboratório de Genética e Biologia Molecular Warwick Estevam Kerr (LabWick), foi montado como espaço de realização de aulas práticas, pesquisa e extensão. Foram convidadas escolas públicas no entorno do Campus Paulo VI, sendo estas a Escola Santa Bárbara, Centro de Ensino Médio Maria José Aragão, Centro de Ensino Médio Paulo VI. A comunidade de alunos, moradores e agricultores no entorno da UEMA (114 pessoas) foi sensibilizada sobre a importância socioambiental das abelhas nativas e sua importância como atividade sustentável e geradora de renda

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

    The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

    Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

    Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt
