Multiscale Design for Robust, Thermal Insulating, and Flame Self-Extinguishing Cellulose Foam.

Cellulose foams are in high demand in an era of prioritizing environmental consciousness. Yet, transferring the exceptional mechanical properties of cellulose fibers into a cellulose network remains a significant challenge. To address this challenge, an innovative multiscale design is developed for producing cellulose foam with exceptional network integrity.

Technology Recommendations to Support Person-Centered Care in Long-Term Care Homes during the COVID-19 Pandemic and Beyond.

The COVID-19 pandemic has exposed persistent inequities in the long-term care sector and brought strict social/physical distancing distancing and public health quarantine guidelines that inadvertently put long-term care residents at risk for social isolation and loneliness. Virtual communication and technologies have come to the forefront as the primary mode for residents to maintain connections with their loved ones and the outside world; yet, many long-term care homes do not have the technological capabilities to support modern day technologies. There is an urgent need to replace antiquated technological infrastructures to enable person-centered care and prevent potentially irreversible cognitive and psychological declines by ensuring residents are able to maintain important relationships with their family and friends.

Valence tautomerism in a [2 × 2] Co grid complex containing a ditopic arylazo ligand.

We describe the structural and magnetic properties of a tetranuclear [2 × 2] Co4 grid complex containing a ditopic arylazo ligand. At low temperatures and in solution the complex is comprised of Co3+ and singly reduced trianion-radical ligands. In the solid state we demonstrate the presence of valence tautomerization via variable temperature magnetic susceptibility experiments and powder-pattern EPR spectroscopy.

Nearly identical bacteriophage structural gene sequences are widely distributed in both marine and freshwater environments.

Primers were designed to amplify a 592-bp region within a conserved structural gene (g20) found in some cyanophages. The goal was to use this gene as a proxy to infer genetic richness in natural cyanophage communities and to determine if sequences were more similar in similar environments. Gene products were amplified from samples from the Gulf of Mexico, the Arctic, Southern, and Northeast and Southeast Pacific Oceans, an Arctic cyanobacterial mat, a catfish production pond, lakes in Canada and Germany, and a depth of ca.

Utilization of herpes simplex PCR assays for cerebrospinal fluid in a pediatric health care setting.

An assessment was made of the utilization and impact of a diagnostic polymerase chain reaction (PCR) assay for the diagnosis of herpes simplex viruses (HSV) 1 and 2 in cerebrospinal fluid of children who attended a Canadian pediatric referral centre. One hundred and three assays were performed on specimens from 103 patients during the period August 1997 to September 1998. Patient ages ranged from newborn to 16 years.

A meta-analysis of mammography screening promotion.

The purpose of this study was to identify factors that influence the effectiveness of interventions in increasing women's use of mammography screening programs. To this end, we conducted a systematic literature review of studies published between 1966 and 1997. In this review, we recorded data about the year and country in which studies were completed, the study design, the methods for measuring screening rates, various sample characteristics, the nature of the intervention, and the resulting screening rates.

Malformations of the brain.

The purpose of this article is to provide a basic outline on which the reader can hold a more elaborate and detailed knowledge of malformations of the brain. The first half of the article consists of a general approach to brain malformations; the second, the shortest possible descriptions of the common brain malformations.
