Thermionic reactor power system: Effects of radiation on integration with Manned Space Station

The application of a thermionic reactor power system to the modular space station is described. The nominal net power is 40 kWe, with the power system designed to be applicable over the power range from 25 to 60 kWe. The power system is designed to be launched by the space shuttle. Radiation protection is provided by LiH neutron shielding and W gamma shielding in a shaped 4 pion configuration, i.e., the reactor is shielded on all sides but not to equal extent. Isodose contours are presented for the region around the modular space station. Levels and spectral distribution of radiation are given for later evaluation of effects on space station experiments. Parametric data on the effects of separation distance on power system mass are presented

Radioisotope thermionic power supply for spacecraft

Power supply design for unmanned electric propulsion missions to outer planets utilizes a store of curium-244 in compact array of capsules as energy source. Supply subassemblies are: heat source, converter equipment which supplies power, and safety equipment. System is designed for a 72,000 hour mission

Postpartum depression (PPD) in teenage mothers due to social determinants of health (SDOH)

The study is a qualitative research study that was done to determine if social determinants of health (SDOH) negatively impact postpartum depression (PPD) in teenage mothers. The SDOH that the study focused on were stigma, social support, and socioeconomic status. The study consisted of interviewing 5 participants. The participants are San Joaquin County residents over the age of 18 years old that have experienced being a teenage mother. The interview included questions about their mental health history, socioeconomic status and more. The findings demonstrated that SDOH negatively impacts PPD in teenage mothers. More than half of the participants shared that they believe they experienced PPD as teenage mothers. All participants also reported to have had their mental health negatively impacted in some way as teenage mothers

Global Perspective: Comparison of Prehospital Use of PAs in the United States and the Netherlands

The prehospital use of advanced clinicians, including physician assistants (PAs), can potentially improve clinical outcomes and reduce unnecessary burdens on emergency departments. This literature review offers a global perspective by comparing the use of PAs in the prehospital setting in the United States and the Netherlands. While there is limited research on clinical outcomes and the clinical utility of advanced clinicians in alternative transport models, the domestic and international examples evaluated in this review have the potential to impact the American healthcare system significantly. The Dutch healthcare system, which utilizes PAs in the prehospital setting, is known for being accessible, affordable, and providing high-quality care. The findings of this literature review may provide a framework for the widespread domestic implementation of advanced clinicians in prehospital medicine in the United States

From Life to Life: Transitioning to Freedom After 45 Years of Incarceration- A Single Subject Case Study

This case study delves into the complex process of reintegrating an elderly parolee who recently emerged from a 45-year-long incarceration within California\u27s state prisons. The research explores this unique individual\u27s reentry experiences and compares them with those of parolees of average age and sentence length. Factors such as family support, educational background, criminal history, health, social support, employment, access to age-appropriate resources, and recidivism rates are meticulously examined to provide valuable insights into the successful reintegration of elderly individuals back into society

Effects of Screen Time on Children\u27s Brain Development: A Scoping Review

In this scoping review, the effects of screen time on cognitive, linguistic, and social-emotional development in children were studied by examining peer-reviewed articles published between 2018 and 2023. A total of 17 peer-reviewed articles were used in the study. The research reported that screen media provide a learning avenue, though it could be detrimental when children spend their time watching more than appropriate screen media. Furthermore, the study indicated that excessive screen media use may harm children’s executive function, which affects academic performance and language development. Related studies have also shown a correlation between excess screen use and problems like obesity, sleep disturbances as well as emotional challenges underscoring the importance of responsible screen practices and parental support. The study also contributes to what parents and educators should do to enable good screen habits in children and further research needs
