Facemasks and ferrous metallurgy: improving gasification reactivity of low-volatile coals using waste COVID-19 facemasks for ironmaking application.

The global pandemic response to COVID-19 has led to the generation of huge volumes of unrecyclable plastic waste from single use disposable face coverings. Rotary hearth furnaces can be used to recover Zn and Fe from non-recyclable steelmaking by-product dusts, and waste plastic material such as facemasks could be utilized as a supplementary reductant for the rotary hearth furnace (RHF), but their fibrous form makes milling and processing to appropriate sizing for RHF application extremely challenging. A scalable method of grinding facemasks to powder by melting and mixing with Welsh coal dust reported herein provides a solution to both environmental challenges.

Cligosiban, A Novel Brain-Penetrant, Selective Oxytocin Receptor Antagonist, Inhibits Ejaculatory Physiology in Rodents.

Introduction: Few treatments are available for men with premature ejaculation (PE); oxytocin (OT) receptor antagonism in the central nervous system (CNS) is a potential new approach.

Aim: To determine if cligosiban selectively inhibits human OT receptors, penetrates the CNS, shows pharmacology in the CNS, and effects ejaculatory physiology in pre-clinical systems.

Methods: Experiments complied with United Kingdom legislation and were subject to local ethical review.

Day-to-day care: the interplay of CNAs' views of residents & nursing home environments.

This qualitative study identified certified nursing assistants' (CNAs') perspectives of nursing home residents and how these perspectives translate into care practices. Data included observations of and interviews with 27 CNAs in three dissimilar nursing homes. All participants were people of color, and all but 3 were immigrants.

Evaluating diversity in nursing education: a mixed method study.

This article presents the findings of a methodical examination of how well one school of nursing was meeting its goal of addressing diversity through its pedagogy. The underlying assumption was that a school's curriculum both shapes and reflects a climate of valuing diversity. This mixed-method evaluation study was conducted in four steps, including a content analysis of all syllabi in the School of Nursing's (SON) curriculum, comparison of the content analysis to students' evaluation of diversity in their education, a survey of the 2006 graduates, and an analysis of faculty responses to the findings.

Lymphoproliferative defects in mice lacking the expression of neurofibromin: functional and biochemical consequences of Nf1 deficiency in T-cell development and function.

Ras plays an essential role in lymphocyte development and function. However, in vivo consequence(s) of regulation of Ras activity by guanosine triphosphatase (GTPase)-activating proteins (GAPs) on lymphocyte development and function are not known. In this study we demonstrate that neurofibromin, the protein encoded by the NF1 tumor suppressor gene functions as a GAP for Ras in T cells.
