Viewpoint: Optimising Cancer Treatment to Reduce Its Environmental Impact

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT It is widely accepted that treatment and care for patients with cancer must and should happen, as it is what everyone would want for themselves and their loved ones. Everyone wants the best possible care, but climate change and the extreme weather that it causes are increasingly affecting everyone including patients in negative ways.

Estimating the Carbon Footprint of External Beam Radiotherapy: Should This Be a Concern for LMICs?

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Purpose This study aims to estimate the carbon footprint associated with external beam radiotherapy in a low‐ and middle‐income country (LMIC) context, specifically at the Uganda Cancer Institute (UCI), and to evaluate whether sustainability should be a priority alongside treatment access in such radiation therapy settings.

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Scattering of thermal He beams by crossed atomic and molecular beams. IV. Spherically symmetric intermolecular potentials for He+ CH_4, NH_3, H_2O, SF_6 [PDF]

open access: yes, 1979
Differential scattering cross sections are measured for He+CH_4, NH_3, H_2O, and SF_6, using the crossed molecular beams technique. These data, which are sensitive to the van der Waals attractive minima and adjacent regions of the intermolecular ...

Palaeolandscape reconstruction of a shallow coastal embayment in Kattegat, Denmark—influence of sea‐level changes during the latest Pleistocene and Holocene

open access: yesBoreas, EarlyView.
We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

影响SF6密度控制器监控特性的因素分析

open access: yesGaoya dianqi, 2010
机械式SF6密度控制器在运行中时有误报警现象。对国内外已使用过的4类SF6密度控制器的不同结构、SF6温度、环温以及使用处海拔高度对监控特性的影响进行了分析。得出,Ⅳ型国产密度控制器质量稳定、监控精度较好;目前使用的SF6密度控制器对GCB/GIS的SF6密度具有一定的监控作用,但不能避免开关运行时出现的SF6密度示数"假高"现象,为消除密度示数"假高"、对环境温度的欠补偿和海拔影响,根本出路是开发新型智能化的SF6密度控制器。
