A Novel, Hybrid, Stereotactic Approach (Radiosurgery and Dual Ommaya Reservoirs) for the Treatment of Mixed (Polycystic and Solid) Craniopharyngioma.

Background: Craniopharyngioma is a difficult entity to treat, which is particularly true for mixed craniopharyngioma (i.e., a mixture of both solid and cystic components).

LET dependence of the response of a PTW-60019 microDiamond detector in a 62MeV proton beam.

This study was initiated following conclusions from earlier experimental work, performed in a low-energy carbon ion beam, indicating a significant LET dependence of the response of a PTW-60019 microDiamond detector. The purpose of this paper is to present a comparison between the response of the same PTW-60019 microDiamond detector and an IBA Roos-type ionization chamber as a function of depth in a 62MeV proton beam. Even though proton beams are considered as low linear energy transfer (LET) beams, the LET value increases slightly in the Bragg peak region.

Floral structure, breeding system and fruit-set in the threatened sub-shrub Tetratheca juncea Smith (Tremandraceae).

Tetratheca juncea Smith (Tremandraceae) has undergone a range contraction of approx. 50 km in the last 100 years and is now listed as a vulnerable sub-shrub restricted to the central and north coast regions of New South Wales, Australia. There are approx.
