A computational model of radiolytic oxygen depletion during FLASH irradiation and its effect on the oxygen enhancement ratio [PDF]

open access: yes, 2019
Recent results from animal irradiation studies have rekindled interest in the potential of ultra-high dose rate irradiation (also known as FLASH) for reducing normal tissue toxicity. However, despite mounting evidence of a "FLASH effect", a mechanism has yet to be elucidated.

Propagating Profiles of a Chemotaxis Model with Degenerate Diffusion: Initial Shrinking, Eventual Smoothness and Expanding [PDF]

open access: yesJ. Differential Equations, 268:414--446, 2020, 2018
We investigate the propagating profiles of a degenerate chemotaxis model describing the bacteria chemotaxis and consumption of oxygen by aerobic bacteria, in particular, the effect of the initial attractant distribution on bacterial clustering. We prove that the compact support of solutions may shrink if the signal concentration satisfies a special ...

15) and from men with prostatovesiculitis 1.4 l 02/108 live cells/hr (SD ± 2.5, range 0-8.2; n = 13). The difference was significant (0.01 > p > 0.005). No significant difference was noted between the oxygen consumption of the spermatozoa in specimens from patients with decreased secretory function of the prostate gland (n = 13) or with asthenospermia

KONSUMSI OKSIGEN BENIH IKAN KERAPU BEBEK (Cromileptes altivelis) UKURAN PANJANG 5-7 CM

open access: yesMarine Fisheries: Jurnal Teknologi dan Manajemen Perikanan Laut, 2012
Disolved oxygen plays an important role for fish living in its life environment. Information on the ammount of oxygen consumption of a fish in certain volume of water is needed in order to give balancing between the ammount of disolved oxygen and fish in

Diffusion and Monod kinetics model to determine in vivo human corneal oxygen-consumption rate during soft contact lens wear

open access: yesJournal of Optometry, 2015
Purpose: We present an analysis of the corneal oxygen consumption Qc from non-linear models, using data of oxygen partial pressure or tension (pO2) obtained from in vivo estimation previously reported by other authors.1 Methods: Assuming that the cornea ...

ironbci. Open source. Brain-computer interface with the embedded board to monitor the physiological subject's condition and environmental parameters [PDF]

open access: yesarXiv, 2021
This manuscript presented brain-computer interface (STM32 and ADS1299) with the embedded board with sensors to monitor the subject's state and environment. To reduce power consumption and device size, we used sensors made in Micro-Electro-Mechanical Systems technology (MEMS) - a gyroscope, accelerometer, and environmental monitoring sensors: CO2 ...

The effect of Ta oxygen scavenger layer on HfO$_2$-based resistive switching behavior: thermodynamic stability, electronic structure, and low-bias transport [PDF]

open access: yes, 2016
Reversible resistive switching between high-resistance and low-resistance states in metal-oxide-metal heterostructures makes them very interesting for applications in random access memories. While recent experimental work has shown that inserting a metallic "oxygen scavenger layer" between the positive electrode and oxide improves device performance ...

Changing the properties of Hf$_{0.5}$Zr$_{0.5}$O$_{2}$ during cyclic repolarization of ferroelectric capacitors with different electrode materials [PDF]

open access: yesarXiv, 2022
The interest in the ferroelectric non-volatile memory as a candidate for low power consumption electronic memories was raised after the discovery of ferroelectricity in hafnium oxide. Doping by different elements of hafnia films allows improving their ferroelectric properties. In this work, the transport experiments are combined with the simulations to
