Underestimation of Sector-Wide Methane Emissions from United States Wastewater Treatment.

An increasing percentage of US waste methane (CH) emissions come from wastewater treatment (10% in 1990 to 14% in 2019), although there are limited measurements across the sector, leading to large uncertainties in current inventories. We conducted the largest study of CH emissions from US wastewater treatment, measuring 63 plants with average daily flows ranging from 4.2 × 10 to 8.

Methane Emissions from Municipal Wastewater Collection and Treatment Systems.

Municipal wastewater collection and treatment systems are critical infrastructures, and they are also identified as major sources of anthropogenic CH emissions that contribute to climate change. The actual CH emissions at the plant- or regional level vary greatly due to site-specific conditions as well as high seasonal and diurnal variations. Here, we conducted the first quantitative analysis of CH emissions from different types of sewers and water resource recovery facilities (WRRFs).

Impact of a Revised Curriculum Focusing on Clinical Neurology and Musculoskeletal Care on a Required Fourth-Year Medical Student Physical Medicine and Rehabilitation Clerkship.

. A Required Fourth-Year Medical Student Physical Medicine and Rehabilitation (PM&R) Clerkship was found to increase students' knowledge of PM&R; however the students' overall rotation evaluations were consistently lower than the other 8 required clerkships at the medical school. .

Traumatic brain injury among North Carolina's veterans.

This article describes the difficulty of diagnosing traumatic brain injury (TBI), treatment protocols provided through the military, an alternative therapy with scientific evidence of its effectiveness in repairing injured brain tissue, challenges faced by brain-injured veterans seeking community reintegration, and state services that are available to help veterans.

Evaluation of technical approaches to tele-electromyography via internet protocol networks.

An exploratory study was conducted to determine the feasibility and clinical utility of remote electromyography (EMG) and nerve conduction studies over Internet Protocol (IP) networks. A progression of technical approaches was attempted until a workable solution was discovered. An evaluation form was completed for each tele-EMG session to attempt to quantify the clinical utility of tele-EMG.

Insulin acts as a myogenic differentiation signal for neural stem cells with multilineage differentiation potential.

Reports of non-neural differentiation of neural stem cells (NSCs) have been challenged by alternative explanations for expanded differentiation potentials. In an attempt to demonstrate the plasticity of NSC, neurospheres were generated from single retrovirally labeled embryonic cortical precursors. In a defined serum-free insulin-containing media, 40% of the neurospheres contained both myogenic and neurogenic differentiated progeny.

Research activities and perspectives of individuals completing a research enrichment program for physiatrists.

Objective: To investigate the research activity and perspectives, and the predictors and barriers to research activity, in a cohort of individuals completing a research enrichment program for physiatrists.

Design: A retrospective cohort study design was utilized. Data collection was accomplished with a mailed survey, which was sent to 68 individuals who had completed the Research Enrichment Program for Physiatrists between 1991 and 1998.
