The outbreak of the novel coronavirus disease, COVID-19 turned into a global pandemic in March 2020. During these unprecedented times, there is an increased demand medical and personal protective equipment (PPE). Since supplies may take long time to meet demand, reusing PPEs will help health care workers their response pandemic. To ensure safety well-being first responders, PPE needs be sterilized before reuse. In this review, we examine various sterilization techniques that can used...
Polarisation asymmetries are measured for the hard exclusive leptoproduction of real photons from a longitudinally polarised hydrogen target. These arise deeply virtual Compton scattering and Bethe-Heitler processes. From data extracted two in azimuthal distribution produced about direction exchanged photon: $$ {\mathcal{A}_{\text{UL}}} with respect to target polarisation {\mathcal{A}_{\text{LL}}} product beam polarisations. Results both compared predictions generalised parton model. The sin...
This study sought to develop and validate an integrated laboratory paradigm of sexual aggression bystander intervention. Participants were a diverse community sample (54% African American) heterosexual males (N = 156) between 21 35 years age who recruited complete the with male friend ostensibly single, female reported strong dislike content in media. viewed sexually explicit or nonsexually film clip as part contrived media rating task made individual choices which show confederate....
This study investigated the mediating effect of trait aggressivity on relation between agreeableness and alcohol-related aggression in a laboratory setting. Participants were 116 healthy male social drinkers 21 30 years age. Agreeableness measured using Big Five Inventory Buss-Perry Aggression Questionnaire, respectively. Following consumption an alcohol or no-alcohol control beverage, participants completed modified version Taylor Paradigm, which electric shocks received from administered...

Purpose To develop and implement an efficient accurate commissioning procedure for small‐field static beam animal irradiation studies on MV research linear accelerator (Linatron‐M9) using radiochromic gel dosimetry. Materials The is a 9 linac with fixed collimator opening of 5.08 cm diameter. Lead collimators were manually placed to create smaller fields 2 × , 1 0.5 . Relative dosimetry measurements performed, including profiles, percent depth dose (PDD) curves, divergence, relative output...
Dose rates, especially from photons and neutrons, inform safety procedures in any radioactive environment. A method for measuring dose rates both particles with one device will simplify current methods surveying fields. We have developed a technique using organic scintillators that is based on the definition of effective dose, extracted energy deposited detector. Using pulse shape discrimination, either neutrons or can be separated. Radiation weighting factors are applied to obtain...
Measurement of dose rates from both neutrons and photons inform radiation safety procedures in many areas nuclear technology. In previous work, we demonstrated a technique for using an organic scintillator to measure neutron photon mixed field with single detector cell. This method can be applied measurements wide variety applications, although different size detectors may required depending on the expected flux. The rate measured should not depend used, factors affect this dependence. work...
Photon active interrogation offers solutions to many of the challenges with preventing proliferation concealed special nuclear material. A pulse shape discrimination capable organic scintillator based detection approach coupled use a conventional linac cost-effective technique. However, there are mitigating non-target emitted signals. In this investigation, background has been reduced through shielding and detector placement, photoneutrons have detected over background. Due pileup, neutrons...
Abstract Traditionally available handheld dosemeters are generally sensitive to only one type of radiation: neutrons or photons. Some also rely on very specific attenuation correlations between response and dose, not scalable in size multiple required characterise mixed-particle fields. The research presented here serves as a proof-of-concept for method simultaneously measure dose rates from photons using particle discriminating organic scintillation detector without the need spectral...

Main text The metrological equivalence of national measurement standards in the field photometry and radiometry is determined by a set key comparisons chosen organised Consultative Committee Photometry Radiometry (CCPR) Comité international des poids et mesures (CIPM), working closely with Regional Metrology Organisations (RMOs). In September 2009 CCPR decided that second round comparison K3 Luminous Intensity be commenced. National Research Council Canada (NRC) was to pilot this comparison....
