The perovskite solid solution (Mg0.5W0.5)(Pb0.5Ni0.5)O3, or MWPN, is synthesized for this study utilizing a solid-state reaction technique. The material's structure, shape, and electrical properties have been meticulously investigated and documented in order to get a better knowledge of its possible uses in electronic devices and sensors. Using X-ray diffraction investigations, we were able to conclude that the structure is tetragonal (space group 141/a(88), z = 4). Dielectric property, impedance spectroscopy, and alternating current conductivity tests have been performed over a wide range of temperatures and frequencies (ranging from 25 °C through 500 °C for temperatures and from 10 kHz to 1 MHz for frequencies). The appearance of a single semicircular arc in the Nyquist analysis findings suggests that the sample in issue is made up of grains. An analog model of an equivalent circuit has been built in order to analyze the electrical functioning. The activation energy for different frequency has been calculated. Methodical study is carried out on the dielectric properties of the material when it is exposed to high temperatures in order to explore the electrical differences that occur between surfaces, grain boundaries, or grains in a material. Relaxor behavior of the sample has been revealed. This is required for both the basic characterization and the construction of devices. [ABSTRACT FROM AUTHOR]

A pandemic leads to disruption and stretching of an existing health care system and its resources. Coronavirus disease 2019 (COVID-19) data show distinct and severe manifestations in children necessitating critical care. Children need prioritization as they are susceptible to COVID-19 as part of the family cluster, varied presentations, and mortality. The purpose of this report is to discuss the optimization of the health care system for pediatric care. The key initiatives were to identify our objectives, bring out changes to the organizational processes, and integrate the same into the existing system. A systems approach to health care delivery by optimizing infrastructure, human resources, materials, funding, leadership, and governance was undertaken. This resulted in creation of distinct COVID-19 and non-COVID-19 service areas, management protocols, and trained health care workers. Partnership was forged with the public health system. This preparedness and continued responses to the demands of the health care system helped us manage children ranging from neonates to adolescents efficiently. Though the health care system is mostly open, acting upon the modifiable factors gave better preparedness in a short time. [ABSTRACT FROM AUTHOR]
