High-Throughput Compatibility Screening of Materials for SF-Alternative Insulation.

Environ Sci Technol

July 2024

Department of Electrical and Computer Engineering, University of Connecticut, Storrs, Connecticut 06269, United States.

With the annual global electricity production exceeding 30,000 TWh, the safe transmission of electric power has been heavily relying on SF, the most potent industrial greenhouse gas. While promising SF alternatives have been proposed, their compatibilities with materials used in gas-insulated equipment (GIE) must be thoroughly studied. This is particularly true as the emerging SF alternatives generally leverage their relatively higher reactivity to achieve lower global warming potentials (GWPs).

To support the work of the Global Conservation Consortium for and update the checklist in the World Flora Online (WFO), we have curated the taxonomic backbone in the WFO by expanding it to include updated nomenclatural information from the International Plant Name Index, missing names present in the World Checklist of Vascular Plants (WCVP), the Botanical Database of Southern Africa (BODATSA), and from the "International register of heather names" database, a data source not readily available online. The result is the most robust database of names to date, including 851 species, 111 subspecies, 244 varieties, and 2787 synonyms, which is a reliable reference for initiatives such as the identification aid, conservation prioritisation, and gap analyses. We disambiguate common orthographic variants within the database and present an overview of these.

Intratumoral (IT) therapy is a powerful method of controlling tumor growth, but a major unsolved problem is the rapidity that injected drugs exit tumors, limiting on-target exposure and efficacy. We have developed a generic long acting IT delivery system in which a drug is covalently tethered to hydrogel microspheres (MS) by a cleavable linker; upon injection the conjugate forms a depot that slowly releases the drug and "bathes" the tumor for long periods. We established technology to measure tissue pharmacokinetics and studied MSs attached to SN-38, a topoisomerase 1 inhibitor.

J Sports Med Phys Fitness

October 2024

Division of Movement Science and Exercise Therapy (MSET), Department of Exercise, Sport and Lifestyle Medicine, Stellenbosch University, Stellenbosch, South Africa.

Background: This study investigates if countries are more focused on certain specializations (one day, climb, sprint, time trial [TT] and grand tour [GC]) in male professional road cycling and if this is possibly linked to the countries landscape (for example, does a mountainous country have more climbers?) and anthropometric characteristics (does the mountainous country also have lighter cyclists?) of their cyclists.

Methods: Body weight, height, procyclingstats (PCS) points per specialty were gathered from 1810 professional cyclists out of 15 countries, as well as the elevation span of those countries. To compare the anthropometric differences between different countries, height was normalized based on the average height of the countries' population, while BMI was used as a correction for body weight.
