Constraints on stellar yields and SNe from gamma-ray line observations
, 1999 Gamma-ray line observations provide a versatile tool for studies of nucleosynthesis processes and supernova physics. In particular, the observation of radioactive species in the interstellar medium probes recent nucleosynthesis activity on various time ...

Indocyanine green fluorescence‐guided sentinel lymph node biopsy: A systematic review
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.Abstract Objectives Accurate staging of cervical lymph nodes is crucial in the management of head and neck cancers (HNCs). Sentinel lymph node biopsy (SLNB) offers a minimally invasive alternative to neck dissection for identifying occult metastases. This review aims to assess the feasibility and effectiveness of indocyanine green (ICG) fluorescence ...

Thinking like a mountain: A land ethical approach to healthcare resource allocation
Bioethics, EarlyView.Abstract Human activity is now having a defining influence on global systems. The Anthropocene epoch requires revisiting our ethical presuppositions to understand our relationship to the earth's life support systems. The Land Ethic of Aldo Leopold proposes an ethic that is diachronic, holistic, and biocentric, in contrast to the synchronic ...

Linac activation of radioisotopes and underground gammaspectrometric analyses [PDF]
arXiv, 2018 After irradiating various medical linac parts with photon beams, we performed underground gamma-ray spectroscopy (GRS) measurements of the samples only a few minutes after the irradiations, in order to observe activated short-lived radioisotopes. Three samples were used: an Elekta Synergy flattening filter never irradiated before, an old flattening ...
