Abstract In the last three years, COMPANY has started the production of eight Surface Production Systems (Floating, Production, Storage and Offloading Units) in the Búzios and Lula fields of the Brazilian pre-salt that have generated technical knowledge, organizational learning and many opportunities to explore in upcoming projects. The lessons learned as well as the organizational knowledge acquired in this period, resulted in a new approach for the commissioning process to apply in COMPANY's coming FPSO projects. During this period, COMPANY identified improvement opportunities and stablished structuring programs focused on adding value to these new assets. The main opportunity identified was to reduce the period required for ramping-up the oil production, considering aggressive target dates for start-up, with high up time on the gas compression systems with minimum flaring. In this manuscript, will be described some of the important actions and changes made in commissioning process that allowed COMPANY to achieve better efficiency and safety in ramp up of new FPSOs in Brazilian pre salt fields.

The transfer of animal genetic improvement strategies in the environments of resource-poor smallholder producers in developing countries has not been successful. Therefore, the access by farmers to sources of animals with high genetic potential is difficult or just not possible. As producers improve or intensify their systems to capture market opportunities, this access need is accentuated. This paper reviews identified constraints to the transfer of breeding plans, the need for a new approach, and the lessons learned in applying a better-targeted approach. The issues and thoughts were derived from the experience of a working group involving the International Center for Agricultural Research in the Dry Areas; Austrian University of Natural Resources and Life Sciences; Argentinean National Institute of Agriculture Technology; Brazilian Agricultural Research Corporation (Embrapa Goats and Sheep); and National Research Institute for Forestry, Agriculture and Animal Production-Mexico. The transfer of breeding strategies in smallholder systems is not a straightforward task. Contrasting a successful application in commercial livestock production environments, the achievement of the primary objectives in smallholder systems requires a holistic approach beyond pure technical matters. Of all identified aspects with direct incidence in the implementation of breeding plans, the lack of specific national policies coupled with long-term funding to support the improvement of smallholder production systems, and the lack of involvement and participation of the communities emerge as issues that gravitate more to achieve sustainability and meet the objectives of a given breeding plan.

Flow Induced Motions are always an important subject during both design and operational phases of an offshore platform life. These motions could significantly affect the performance of the platform, including its mooring and oil production systems. These kind of analyses are performed using basically two different approaches: experimental tests with reduced models and, more recently, with Computational Fluid Dynamics (CFD) dynamic analysis. The main objective of this work is to present a new approach, based on an analytical methodology using static CFD analyses to estimate the response on yaw motions of a Tension Leg Wellhead Platform on one of the several types of motions that can be classified as flow-induced motions, known as galloping. The first step is to review the equations that govern the yaw motions of an ocean platform when subjected to currents from different angles of attack. The yaw moment coefficients will be obtained using CFD steady-state analysis, on which the yaw moments will be calculated for several angles of attack, placed around the central angle where the analysis is being carried out. Having the force coefficients plotted against the angle values, we can adjust a polynomial curve around each analysis point in order to evaluate the amplitude of the yaw motion using a limit cycle approach. Other properties of the system which are flow-dependent, such as damping and added mass, will also be estimated using CFD. The last part of this work consists in comparing the analytical results with experimental results obtained at the LOC/COPPE-UFRJ laboratory facilities.

Abstract African genomic medicine and microbiome datasets are usually not well characterized in terms of their origin, making it difficult to find and extract data for specific African ethnic groups or even countries. The Pan-African H3Africa Bioinformatics Network (H3ABioNet) recognized the need for developing data portals for African genomic medicine and African microbiomes to address this and ran a hackathon to initiate their development. The two portals were designed and significant progress was made in their development during the hackathon. All the participants worked in a very synergistic and collaborative atmosphere in order to achieve the hackathon's goals. The participants were divided into content and technical teams and worked over a period of 6 days. In response to one of the survey questions of what the participants liked the most during the hackathon, 55% of the hackathon participants highlighted the familial and friendly atmosphere, the team work and the diversity of team members and their expertise. This paper describes the preparations for the portals hackathon and the interaction between the participants and reflects upon the lessons learned about its impact on successfully developing the two data portals as well as building scientific expertise of younger African researchers. Database URL: The code for developing the two portals was made publicly available in GitHub repositories: [https://github.com/codemeleon/Database; https://github.com/codemeleon/AfricanMicrobiomePortal].

The scientific community has made great efforts in advancing magnetic hyperthermia for the last two decades after going through a sizeable research lapse from its establishment. All the progress made in various topics ranging from nanoparticle synthesis to biocompatibilization and in vivo testing have been seeking to push the forefront towards some new clinical trials. As many, they did not go at the expected pace. Today, fruitful international cooperation and the wisdom gain after a careful analysis of the lessons learned from seminal clinical trials allow us to have a future with better guarantees for a more definitive takeoff of this genuine nanotherapy against cancer. Deliberately giving prominence to a number of critical aspects, this opinion review offers a blend of state-of-the-art hints and glimpses into the future of the therapy, considering the expected evolution of science and technology behind magnetic hyperthermia.

AbstractMalaria remains a major cause of morbidity and mortality in Africa, particularly in children under five years of age. Availability of effective anti-malarial drug treatment is a cornerstone for malaria control and eventual malaria elimination. Artemisinin-based combination therapy (ACT) is worldwide the first-line treatment for uncomplicated falciparum malaria, but the ACT drugs are starting to fail in Southeast Asia because of drug resistance. Resistance to artemisinins and their partner drugs could spread from Southeast Asia to Africa or emerge locally, jeopardizing the progress made in malaria control with the increasing deployment of ACT in Africa. The development of triple artemisinin-based combination therapy (TACT) could contribute to mitigating the risks of artemisinin and partner drug resistance on the African continent. However, there are pertinent ethical and practical issues that ought to be taken into consideration. In this paper, the most important ethical tensions, some implementation practicalities and preliminary thoughts on addressing them are discussed. The discussion draws upon data from randomized clinical studies using TACT combined with ethical principles, published literature and lessons learned from the introduction of artemisinin-based combinations in African markets.

Sex is a common baseline factor collected in studies that has the potential to be a prognostic factor (PF) in several clinical areas. In recent years, research on sex as a PF has increased; however, this influx of new studies frequently shows conflicting results across the same treatment or disease state. Thus, systematic reviews (SRs) addressing sex as a PF may help us to better understand diseases and further personalize healthcare. We wrote this article to offer insights into the challenges we encountered when conducting SRs on sex as a PF and suggestions on how to overcome these obstacles, regardless of the clinical domain. When carrying out a PF SR with sex as the index factor, it is important to keep in mind the modifications that must be made in various SR stages, such as modifying the PF section of CHARMS-PF, adjusting certain sections of QUIPS and extracting data on the sex and gender terms used throughout the studies. In this paper, we provide an overview of the lessons learned from carrying out our reviews on sex as a PF in different disciplines and now call on researchers, funding agencies and journals to realize the importance of studying sex as a PF.

PurposeThis article reports on the background, the conceptual ideas and the lessons learned from over more than 20 years of IC Statements and Management with a country focus on Germany and some international developments. It calls for an integrated management approach for IC and offers case study evidence on how to accomplish this quest.Design/methodology/approachReport on the German initiative “Intellectual Capital Statement made in Germany” (ICS m.i.G.). A brief review of the literature describes the background and theoretical foundation of the German IC method. A short description of the method is followed by four detailed case studies to illustrate long-term impact of IC management in very different organizations. A discussion of Lessons Learned from more than 200 implementations and an outlook on current and future developments finalizes the article.FindingsIC Statements made in Germany (ICS m.i.G.) was successful in providing a framework to systematically identify IC, evaluate the status quo of IC relative to the strategic requirements, visualize interdependencies of IC, business processes and business results as well as to connect IC reporting with internal management routines and external communication. However, ICS is not an insulated method but delivers the maximum benefit when integrated with strategy development, strategy implementation, business process optimization accompanied by change management routines. Strong ties to human resource management, information technology departments, quality management, research and development teams as well as business operations as the core of an organization help to yield the most for ICS m.i.G. Over time, the focus of managing IC changes and maturity leads to deutero learning.Practical implicationsICS m.i.G. proved easy to apply, cost efficient for SMEs, larger corporations and networks. It helps to better accomplish their objectives and to adjust their business models. The guidelines in German and English as well as a software application released were downloaded more than 100,000 times. A certification process based on a three-tier training module is available and was successfully completed by more than 400 practitioners. ICS m.i.G. is supporting current standards of knowledge management, such as ISO 9001, ISO 30401 or DIN SPEC PAS 91443 and therefore will most likely have a continuing impact on knowledge-based value creation.Originality/valueThis paper reports lessons learned from the country-wide IC initiative in Germany over the last 20 years initiated and supported by the authors. Several elements of the method have been published over time, but so far no comprehensive view on Lessons Learned had been published.

Within WLCG, the DESY site in Hamburg is one of the largest Tier-2 sites with about 18500 CPU cores for Grid workloads. Additionally, about 8000 CPU cores are available for interactive user analyses in the National Analysis Factory [NAF]. After migrating these two batch systems onto a common HTCondor based set-up during the previous four years, we recapitulate the lessons learned during the transition especially since both use cases differ in their workloads. For Grid jobs start-up latencies are negligible and the primary focus is on an optimal utilization of the resources. Complementary, users of the NAF expect a high responsiveness of the batch system as well as the storage for interactive analyses. In this document, we will also give an outlook to future developments and concepts for the DESY high-throughput computing. In the ongoing evolution of the HTC batch system, we are exploring how to integrate anonymous jobs with the batch system as back-end for Function-as-a-Service workflows as well as an option for dynamic expansions to remote computing resources.

Organization members often complain about insufficient time to reflect collectively as they grapple with constant significant changes. The Learning History methodology can support this collective reflection. Given the scant empirical studies of this action research approach, the present paper fills this gap by giving an overview of this methodology and by presenting a qualitative study that answers the following research question: How does the Learning History methodology contribute to collective reflection among organization members during major organizational change? To answer this question, an empirical research project was led within five healthcare organizations in Canada during their implementation of the Planetree person-centered approach to management, care, and services. The data set includes 150 semi-structured interviews, 20 focus groups and 10 feedback meetings involving organization members representing all hierarchical levels in the five participating institutions. The results highlight the five types of contributions of the Learning History methodology to collective reflection within the five institutions that participated in the study: 1) a process of expression, dialogue, and reflection among organization members; 2) a portrait of the change underway; 3) a support tool for the change process; 4) a vector for mobilizing stakeholders; and 5) a source of organizational learning.  The results also show how organization members’ collective reflection is built through the various stages of the Learning History methodology. By demonstrating that this collective reflection leads to true organizational learning, the findings position the Learning History as a research-action method useful both from a research standpoint and as an organizational development tool. In the conclusion, lessons learned using the LH approach are shared from a researcher’s perspective. This paper should interest researchers and practitioners who seek research methodologies that can offer an infrastructure for collective reflection to support organizational change and learning.
