Twisted fibers enable drop flow control and enhance fog capture.

Drop-fiber interactions are fundamental to the operation of technologies such as atmospheric fog capture, oil filtration, refrigeration, and dehumidification. We demonstrate that by twisting together two fibers, a sliding drop's flow path can be controlled by tuning the ratio between its size and the twist wavelength. We find both experimentally and numerically that twisted fiber systems are able to asymmetrically stabilize drops, both enhancing drop transport speeds and creating a rich array of new flow patterns.

A Description of Suspected Concussions in Football-Related Activities among K-12 Students in Utah.

The circumstances and nature of concussions among youth who play tackle, flag, or touch football are not well understood. This study used data from Utah's Student Injury Reporting System (SIRS) to explore suspected concussions among K-12 students sustained during participation in football-related activities (tackle, flag, or touch football). Descriptive statistics and chi-square analyses showed that 54.

Gravi-Sensitivity of Mosses and Their Gravity-Dependent Ontogenetic Adaptations.

Gravi-morphoses affect the variability of plants and are the morphogenetic adaptation to different environmental conditions. Gravity-dependent phenotypic plasticity of gametophytes as well as gravi-sensitivity of moss protonemata in microgravity and simulated microgravity conditions are discussed. The moss protonema, a filamentous multicellular system, representing a juvenile stage of moss development, develops as a result of the elongation and division of the apical cell.

Training dementia care professionals to help caregivers improve the management of behavioral and psychological symptoms of dementia using the DICE Approach: A pilot study.

Most persons living with dementia (PLWD) exhibit behavioral or psychological symptoms of dementia (BPSD) over the course of the illness. The DICE Approach (DICE) is a framework that enables caregivers to identify, evaluate, and manage BPSD. This pilot pre-post test study examined the effects of DICE training on dementia care professionals' self-efficacy, knowledge, and attitudes regarding care of patients with BPSD.

Oscillations of Drops with Mobile Contact Lines on the International Space Station: Elucidation of Terrestrial Inertial Droplet Spreading.

We analyze shape oscillations of sessile water drops with fully mobile contact lines (CL) aboard the International Space Station. The unique microgravity environment enables the study of centimeter-sized droplets with associated inertial-capillary motions. Plane-normal substrate vibrations induce resonance behaviors quantified by frequency scans from which the natural frequencies and mode shapes are identified for nine different hydrophobic surfaces.
