Radiation sterilization [PDF]

Journal of Clinical Pathology, 1961
The sterilization by radiation of disposable medical items has been investigated. Various vegetative and spore-bearing bacteria have been irradiated and results indicate that 2·5 Mrad can be recommended to give a high degree of sterility. Spores of B. pumilus (E.601) showed such resistance that it might be a suitable test organism for determining the ...

Influence of cellular models and individual factor in the biological response to head CT scan exams

European Radiology Experimental, 2022
Background While computed tomography (CT) exams are the major cause of medical exposure to ionising radiation, the radiation-induced risks must be documented. We investigated the impact of the cellular models and individual factor on the deoxyribonucleic

The netrin-1 receptor UNC5C contributes to the homeostasis of undifferentiated spermatogonia in adult mice

Stem Cell Research, 2022
In adult testis, the cell mobility is essential for spermatogonia differentiation and is suspected to regulate spermatogonial stem cell fate. Netrin-1 controls cell migration and/or survival according to the cellular context. Its involvement in some self-

Self-similar Radiation from Numerical Rosenau-Hyman Compactons

, 2007
The numerical simulation of compactons, solitary waves with compact support, is characterized by the presence of spurious phenomena, as numerically-induced radiation, which is illustrated here using four numerical methods applied to the Rosenau-Hyman K(p,

Sorting and Manipulation of Human PGC-LC Using PDPN and Hanging Drop Cultures

Cells, 2022
The generation of oocytes from induced pluripotent stem cells (iPSCs) was proven efficient with mouse cells. However, no human iPSCs have yet been reported to generate cells able to complete oogenesis.

Low altitude energetic electron lifetimes after enhanced magnetic activity as deduced from SAC-C and DEMETER data [PDF]

Annales Geophysicae, 2010
When flux enhancements of energetic electrons are produced as a consequence of geomagnetic storm occurrence, they tend to vanish gradually when the magnetic activity calms down and the fluxes decay to quiet-time levels.

Approach to Parton Equilibration [PDF]

, 1995
Perturbative QCD-based models of parton production and equilibration in ultrarelativistic heavy ion collisions are reviewed with an emphasis on the treatment of quantum interference effects.

Radiatively and thermally driven self-consistent bipolar outflows from accretion discs around compact objects

, 2013
We investigate the role of radiative driving of shock ejected bipolar outflows from advective accretion discs in a self consistent manner. Radiations from the inner disc affects the subsonic part of the jet while those from the pre-shock disc affects the

Deterministic evaluation of safety parameters and neutron flux spectra in the MNSR research reactor using DRAGON-4 code

Journal of Radiation Research and Applied Sciences, 2018
Comparative studies for conversion of the fuel from high enriched uranium (HEU) to low enriched uranium (LEU) in the reactor (MNSR) were performed using DRAGON code deterministic. In this work the HEU fuel (UAl4-Al, 90% enriched with Al-clad) and LEU (12.
