This paper analyses the feasibility of using the cutaneous saphenous nerve (CSN) as a source of peripheral nerve graft (PNG). In 34 fresh dog cadavers, the PNG length (PNGL) was measured, pattern of collateralization was studied, fascicles diameter and number were assessed at multiple levels along the length of the CSN (levels of section A, B, C and D) and surgical approach was described. The PNGL was correlated to femoral length. The pattern of CSN collateralization was consistent for all but 2 of the dogs. The average cross section diameter and fascicle number of the CSN was 2.0 to 0.1 mm (1 to 7 fascicles). CSN provides a large-sized, easily accessible nerve graft that could be used to bridge nerve gaps in the dog.

This paper comes back on the accuracy of the surrogate-reaction method (SRM) historically used for neutron-induced average partial cross sections inference from measured surrogate-reaction probabilities. The SRM level of performance is examined in relation to a reasonably accurate reference calculation performed with the 𝒜𝒱𝒳𝒮ℱ-ℒ𝒩𝒢 code [1] through a challenging test case : the 240Pu* compound system. This paper argues on some ingredients of the reference calculation [2] and returns some hints about the failure now well-known of the neutron-induced γ average cross section inference. It shows also that in some special cases, the SRM can be poorly accurate also in terms of neutron-induced fission average cross section inference.

Cross Section Formula

The average cross section [Formula: see text] for the Penning reaction between Kr (1s5) and [Formula: see text] atoms has been obtained from a comparative study of Kr–U and Kr–Th gas combinations in a hollow-cathode-type generator. The experimental value obtained is 2,8 × 10−15 cm2 ± 50%.
