Background: In the current study the effect of shielded colpostat on rectum received dose was calculated in cervical brachytherapy using Monte Carlo (MC) method. Materials and Methods: Two 60Co sources of GZP6 brachytherapy unit used for intracavitary treatments were simulated using MCNPX Monte Carlo code. Also the two types of colpostats including shielded and unshielded were simulated inside ...

Objective(s): Lipid-based nanoparticles (NLP) are PEGylated carriers composed of lipids and encapsulated nucleic acids with a diameter less than 100 nm. The presence of PEG in the NLP formulation improves the particle pharmacokinetic behavior. The purpose of this study was to prepare and characterize NLPs containing MDR1 siRNA and evaluate their cytotoxicity and cellular uptake. MDR1 siRNA coul...

Partial discharge occurs a lot in shielded dielectric power cables. Partial discharge pulses are high-frequency electromagnetic waves that propagate in the shielded dielectric power cables. This chapter will study partial discharge propagation and detection in shielded dielectric power cables.

To the Editor: The results of the study, “Impact of a Shielded Safety Syringe on Needlestick Injuries Among Healthcare Workers,” in the June 1992 issue (1992;13:349353) are encouraging. Technology that keeps the worker’s hands behind the needle at all times and covers the needle after use should significantly lower the rate of needlestick injuries. However, we noted the following inconsistencie...

Abstract Many western countries used shielding (extended self-isolation) of people presumed to be at high-risk from COVID-19 protect them and reduce healthcare demand. To investigate the effectiveness this strategy, we linked family practitioner, prescribing, laboratory, hospital death records compared outcomes among shielded non-shielded individuals in West Scotland. Of 1.3 million population,...

This paper presents circuit models to analyze the conducted susceptibility of multiconductor shielded cables in frequency domains using Branin’s method, which is referred to as the method of characteristics. These models, which can be used directly in the time and frequency domains, take into account the presence of both the transfer impedance and admittance. The conducted susceptibility is stu...
