In this work, we make the ansatz that economic production is reduced to the energy made available to the economy. In (Illig and Schindler, BioPhys Econ Resour Qual 2(1):1, 2017) the price of oil was expressed as a function of the size of the economy, the cost share of oil, and the quantity of oil extracted. We clarify assumptions needed to use this explicit price equation to study prices. Using the current extraction rate, the previous year's extraction rate, and interest rates of the Federal Reserve we use linear regression to give a model for oil prices from 1966 to 2018. The model verifies that deductions made from the explicit price equation are consistent with empirical data over the given time period. Our analysis indicates that the contraction phase of world oil extraction began in 2020 and that it will be characterized by relatively low oil prices. We present some challenges and opportunities for building a future economy if our assumptions prove valid.

Gout is a prevalent metabolic disorder characterized by urate crystal accumulation in joints, leading to acute arthritis and tophi formation. Despite advancements in management, the incidence and prevalence of gout have been increasing globally, particularly in China. This study analyzed data from the Global Burden of Disease Injuries and Risk Factors Study (GBD) to evaluate trends in gout from 1990 to 2021.

In Pakistan, a setting with high gender inequality, the relationship between female agency and mental health has not been studied longitudinally or beyond a defined life stage like pregnancy. Using data from the Bachpan cohort of mother-infant dyads in Pakistan, we investigated female agency and depression at two life stages: perinatal (third trimester to 6-months postpartum; n = 1154) and beyond (3- to 4-years postpartum). Modified Poisson models estimated adjusted prevalence ratios (PR) for probable depression (PHQ-9) associated with female agency (freedom of movement and participation in household decision-making) at the two life stages.

Microtiter-plate-based systems are unified platforms of high-throughput experimentation (HTE). These polymeric devices are used worldwide on a daily basis-mainly in the pharmaceutical industry-for parallel syntheses, reaction optimization, various preclinical studies and high-throughput screening methods. Accordingly, laboratory automation today aims to handle these commercially available multiwell plates, making developments focused on their modifications a priority area of modern applied research.

To deal with the increasingly severe climate crisis and environmental pollution, China launched a nationwide real-time air quality monitoring program in three batches, a milestone moment in its environmental governance history. Using the time-varying difference-in-differences model, this study explores the synergies of this program across 284 cities from 2009 to 2019. The findings are as follows: (1) With environmental information disclosed, the national air quality monitoring program can reduce the outdoor fine particulate matter concentration by an overall effect of 3.

Waste printed circuit boards (WPCBs) are a significant component of electronic waste (e-waste) and are among the fastest-generating waste flows. The potentially negative impacts caused by e-waste on the environment and human health pose an increasingly apparent threat to people's everyday lives and well-being. The nonmetallic fraction (predominantly carbon) of WPCBs is characterized by heavy weight, low resource value, and complex composition, and these characteristics significantly restrict the recycling of the WPCBs to achieve a circular economy.
