The free vibration frequency responses of the laminated composite structure with a cut-out of variable shapes (square/circular/elliptical), position (center/eccentric) and orientation (parallel/inclined) are investigated for the first time in this research including geometrical shapes. The eigenvalues are obtained computationally for the cut-out borne structure via a linear isoparametric finite element model of the composite structure in association with cubic-order of displacement kinematics. Also, a coupled code is prepared in MATLAB environment by joining the higher-order formulation and the simulation model (ABAQUS) to achieve the generic form to investigate the influential cut-out parameter (shape, size and position) on their eigenvalues. Further, a series of experimentations are carried out using the cut-out borne composite panel and compared with the computational frequency, including the experimental properties. Finally, the key behavior is surveyed through different kinds of numerical examples for various design constraint parameters including the cut-out relevant factors (shape, position and orientation) to show the subsequent inclusiveness of the proposed model.

5548 Background: RMSGM are not amenable to the usual treatment with surgery and post-operative radiotherapy. The role of chemotherapy (CT) for RMSGM is palliative only. VNB showed moderate activity in our experience (Bull Cancer 85:892;1998) and in a randomized phase II trial we had demonstrated that the DDP+VNB combination had a better outcome than VNB alone (Cancer 91:541; 2001). In this abstract we report the final results of this combination in 60 cases. Methods: From April 2001 to February 2009 , 60 cases with RMSGM were enrolled. All patients received the following regimen: DDP 80 mg/sm d.1 + VNB 25 mg/sm d. 1,8 every 3 weeks. The study foresees a maximum of 6 cycles. Results: Patients characteristics were as follows: 35 males (58%) and 25 females (42%).; median age: 56 yrs (range 20-68); median ECOG PS: 1 (0-2); histology: adenocarcinoma 15 (25%), adenoid cystic ca. 34 (57%), others 11 (18%); site of disease: local 30 (50%) , mts +/- local 30 (50%). Forty-two pts received DDP+VNB as first line CT (70%) while 18 pts (30%) had the combination as second-line CT (30%). After a median of 5 cycles of first line DDP+VNB responses were: 3 CR (7%), 10 PR (24%), 14 NC (33%) and 15 PD (36%). After a median of 4 cycles of second line CT responses were: 0 CR; 1 PR (5%), 6 NC (33%) 11 PD (62%). Median survival: 10 months (3-29) for first line CT ; 4 months (1-12) for second line CT. G3-4 toxicity: neutropenia (20%), anemia (12%), nausea/vomiting (12%) , peripheral toxicity (3%). Conclusions: DDP+VNB is an effective first line CT in RMSGM ; second line CT has a low palliative activity. Toxicity seems acceptable. This regimen could be suitable for an integration with new biologic target agents.

Abstract A parliamentary inquiry into the Irish banking collapse was formally established in November 2014, tasked with examining relevant issues from the period of January 1992 to December 2013. In focusing on the role played by the media - and where reportage may have impacted on, or contributed to, the crisis - the Banking Inquiry heard from eight senior media executives who held either commercial or editorial positions in four media organisations in Ireland during the period of the economic boom and subsequent collapse. This article focuses on the engagement of these media witnesses with the inquiry, drawing on written submissions and oral evidence. Having reviewed the place of journalism in a democracy and examined the role of journalism during the economic crisis, the article considers the Banking Inquiry’s final report, specifically in relation to the media. The review concludes that this parliamentary inquiry did not assist in advancing a serious understanding of the work undertaken by the Irish media in the pre-2007 period and that, ultimately, for all involved this engagement was a missed opportunity.
