    [EN] This study aims at the preliminary assessment in designing a complete stand-alone industrial facility to produce injection molded parts for the automotive industry. A draft design solution to allow the company to evaluate the capital investment was performed giving an estimated solution in project profitability. Proposed successive design steps were developed. It includes the definition of input data and information, quantity determination, plat layout diagrams, machine selection, selection of material handling equipment, plant layout design including space requirements of production centers, aísles, support functions. Moreover, the outdoor facility masterplan design is also proposed. Finally, investment calculation via cash flow analysis is calculated.Yudianto, A.; Tan, H.; Qu, Z.; Xue, Q.; Naveen, A.; Mushtaq, M.; Gopi, K. (2020).

    Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

    Dancing with a giant: The effect of Wal-Mart's entry into the U.K. on the performance of European retailers

    The authors examine the value-destroying and value-enhancing effects of a giant player's foreign entry on incumbents operating in that region. They use Wal-Mart's entry into the United Kingdom, through its acquisition of Asda, as the empirical context. Drawing on the marketing, strategy, and finance literature streams, the authors develop hypotheses as to why some incumbents are negatively affected whereas others actually may benefit from the entry of a giant competitor. Their measure of performance impact is the change in shareholder value around the announcement date, which has recently been recognized as an important metric to evaluate the effectiveness of marketing actions. The authors find strong support for the conceptual model, which distinguishes between the seriousness of the threat to the incumbents and their capacity to withstand the threat. The authors validate their findings using three alternative measures of company performance: percentage growth in the incumbent retailer's sales, earnings before interest and taxes, and return on assets between 1998 (the year before the Asda takeover) and 2002 (three years after the takeover). The authors discuss various managerial implications of their results. By acting proactively, incumbents can mitigate the negative performance consequences, while maximally benefiting from the positive implications of a giant competitor's entry

    Fracture fixation in the operative management of hip fractures (FAITH): an international, multicentre, randomised controlled trial

    Background Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. Methods For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries. Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws. Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups. The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function. Analyses followed the intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT00761813. Findings Between Mar
