The presentation includes monitoring results of the companies participating in the ESST expert study group on “Nitrite in feed”. It will be obvious that the complex behaviour of nitrite in the sugar extraction process overlaps with external effects such as growth condition of the beet which are not under the control of the process owner. Currently the lack of reliable and validated analytical methods do not allow to comply to the questionable maximum nitrite limit for animal feed materials.

Common Frame Of Reference

In 2005 a French working group published an Avant-projet de réforme du droit des obligations et de la prescription (“Avant-projet Catala”).1 At the end of 2007 a Draft Common Frame of Reference (“DCFR”) was submitted to the European Commission by the Study Group on a European Civil Code and the Research Group on EC Private Law (Acquis Group).2 How much ink should we spill over such academic proposals for legislative reform, especially if there are misgivings as to substance, content and legitimacy and doubts as to the prospects for implementation? In an attempt to learn from these projects this paper aims to evaluate and reflect on the position of legal scholars on the political legal scene, and to compare the content of some selected provisions. The overall objective is to investigate how the Avant-projet Catala, a proposal to reform the French Civil Code, and the DCFR, a proposal which looks very much like a European Civil Code, fit together: do these projects have different goals or are they in competition with one another? More particularly, this paper investigates whether these French3 and European initiatives are conducive to creating a more European private law or, on the contrary, whether they reinforce legal nationalism.

Abstract The Japan Clinical Oncology Group–Radiation Therapy Study Group (JCOG-RTSG) has initiated several multicenter clinical trials for high-precision radiotherapy, which are presently ongoing. When conducting multi-center clinical trials, a large difference in physical quantities, such as the absolute doses to the target and the organ at risk, as well as the irradiation localization accuracy, affects the treatment outcome. Therefore, the differences in the various physical quantities used in different institutions must be within an acceptable range for conducting multicenter clinical trials, and this must be verified with medical physics consideration. In 2011, Japan’s first Medical Physics Working Group (MPWG) in the JCOG-RTSG was established to perform this medical-physics-related verification for multicenter clinical trials. We have developed an auditing method to verify the accuracy of the absolute dose and the irradiation localization. Subsequently, we credentialed the participating institutions in the JCOG multicenter clinical trials that were using stereotactic body radiotherapy (SBRT) for lungs, intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) for several disease sites, and proton beam therapy (PT) for the liver. From the verification results, accuracies of the absolute dose and the irradiation localization among the participating institutions of the multicenter clinical trial were assured, and the JCOG clinical trials could be initiated.
