Hang-on parts of modern passenger cars such as doors and hoods are mainly manufactured by a two-step hemming process during assembly, whereby the edge of the already deep-drawn, blanked and flanged outer panel is further bent to a hem. This hem ties together outer and inner panel of hang-on part. Owing to the bending processes during hemming, large amounts of strain occur on the outer side of the hemming rope, causing local roughening of the formed sheet surface, which may become critical in terms of the quality of the coated component. In this study, the surface roughening during bending and hemming of a typical aluminum sheet material for hang-on parts is examined. In a first step, the roughening process is determined as a function of the bending angle and plastic strain during bending and hemming. Then hemming was further investigated to describe surface roughening as a function of the flanging radius and pre-strain level. The results of the plate bending test and hemming test at identical bending angles and plastic strain levels showed different levels of surface roughening, caused by the non-congruent size and local position of the forming zone in both bending methods. © 2015 Springer-Verlag France Source

Background and Objectives: Being notified of a false-positive infectious disease marker result can cause psychological distress in blood donors. A new notification process, informing donors of the possibility of re-entry, was compared with the previous one in which donors were indefinitely deferred to evaluate the mitigating effect on donors' psychological distress levels. Materials and Methods: Two groups of donors, 'deferred donors' (DD) and 'donors eligible for re-entry' (DER), completed a questionnaire involving 5-point scales. Levels of psychological distress, attitude towards blood donation, desire to donate blood in the future and perception of notification process quality were assessed. Results: Attitudes towards blood donation (P = 0·0276) (DD: 3·94 ± 0·11 vs. DER 4·21 ± 0·09) and perceived quality of communication (P = 0·0108) (DD: 2·72 ± 0·12 vs. DER 3·08 ± 0·10) were significantly improved with the new notification process. No significant difference was found between groups in psychological distress levels or desire to donate blood in the future. Conclusion: Informing donors of the possibility of re-entry appears to contribute to maintaining a positive predisposition towards future blood donation. It does not, however, appear to alleviate the distress felt after being notified of a false-positive infectious disease marker result, nor does it increase willingness to give blood again in the future. © 2014 International Society of Blood Transfusion.

Patients with cancer may suffer from malnutrition due to cachexia, this maybe secondary to treatment, psychological factors and/or gastrointestinal (GI) obstruction. GI obstruction indicates a need for TPN. Does this apply to patients with incurable terminal cancer? How does TPN affect longevity and quality of life in this group of patients? What is the course of TPN treatment compared with patients receiving TPN due to nonmalignant GI failure (NMGIF). The aim of this work was to help define the role of TPN in patients with incurable cancer and GI obstruction. Data of all patients treated by home TPN (HTPN) 2003-2009 were collected prospectively and analyzed. Sixty-eight patients were treated with HTPN, 30 of them for NMGIF. Mean age was 52 years (37-87). Primary sites of cancer were ovary (9), stomach (8) and others (11). Median survival of patients with malignant GI failure (MGIF) was 140 days (20-783) with no difference with regard to age, gender, primary diagnosis, BMI, percentage of weight loss and albumin level. Patients with MGIF and a higher performance score had longer survival. Patients with MGIF suffered significantly higher rates of overall and infectious complications per treatment days [P < 0.001]. TPN for MGIF incurable patients with cancer prolongs survival but at the cost of frequent complications. TPN is indicated in a selected group of MGIF. We do not have the tools to predict in which patients the benefits will outweigh the cost, but we found variables which may assist caregivers to make clinical and empathic decisions individually. © 2010 Springer Science+Business Media, LLC.

Paulo Products Co., St. Louis, Mo., announces that its Kansas City Division is now AS9100 certified, and joins the Cleveland Division in being both AS9100 certified and Nadcap accredited. The AS9100 certification will reinforce the Kansas City Division's position as a leading aerospace heat treating facility. "I am proud of the accomplishments of our Kansas City Division. AS9100 certification will further assure our aerospace customers that Paulo has the systems in place to provide the quality heat treating services required for the integrity and safety of parts used in aerospace applications," says Ben Rassieur, President. Led by David Mailes, Director of Quality, the Paulo quality team worked hard through 2015 to secure the AS9100 certification. Kansas City Division Quality Assurance Manager Mark Affolter had a very busy 2015. In addition to working towards AS9100, Mark was faced with several audits, as the Kansas City Division maintained ISO9001 and ISO14001 while also securing Boeing approval. Leveraging prior experience from the Cleveland Division certification, benchmarks were established that proved helpful for the Kansas City certification. Additional support came from the Kansas City Division sales team of Jeb Clement and Curt Heineck, as well as Plant Manager Tee Rassieur. The Kansas City Division is committed to growing with customers and meeting the stringent requirements of the aerospace industry.
