An improved fingernail trimmer
… design and develop a first iteration prototype fingernail trimming device. The device was designed to make nail trimming easier, especially for people with poor eyesight, limited hand coordination or problems with hand steadiness. As such the device was designed to meet several design …

Life history and microbiome analysis of freshwater fingernail clams (sphaeriidae) exposed to trace metal pollution
… influences the life histories of freshwater fingernail clams (Sphaeriidae) and if fingernail clams are selecting a different microbial community if chronically exposed to metal mixtures than if in a site that is not impacted by metal pollution. Fingernail clams are small, cosmopolitan, …

Design and analysis of fingernail sensors for measurement of fingertip touch fouce and finger posture
… by measuring changes in the coloration of the fingernail; hence, the sensor is mounted on the fingernail and does not interfere with bending or touching actions. Specifically, the fingernail is instrumented with miniature light emitting diodes (LEDs) and photodetectors in order to measure …

Optical detection of finger pressure through utilization of nailbed color changes
… finger is pressed by visually examining a user's fingernail coloration. Unlike other finger-based controllers that primarily depend on covering the finger pad, this method of sensing allows for accurate measurements without impairing a user's tactile sense. First the color change of a fingernail …

Determining the effects of non-native brook stickleback (Cualea inconstans) on the lentic systems at Turnbull National Wildlife Refuge, Cheney, WA
… and macrophyte community characteristics, fingernail clam population and stress metrics, and water quality parameters in twelve lentic systems on the refuge; those that contain brook stickleback or are fish free, and are either temporary or permanent. The fish free, permanent lentic systems …

Fabrication, Characterization and Cellular Interactions of Keratin Nanomaterial Coatings for Implantable Percutaneous Prosthetics
… interface already found in the human body, the fingernail-skin interface, which is infection-free and mechanically stable. The same keratins that make up the cortex of human hair fibers are found in the fingernail. These cortical human hair keratins can be extracted and purified, and …

Rapid Scan Electron Paramagnetic Resonance (EPR) and Digital EPR Development
… spin-labeled proteins, irradiated tooth and fingernail samples were demonstrated in this dissertation. The scan width has been increased from 55 G to 160 G. The signal to noise (<em>S/N</em>) improvement for slowly tumbling spin-labeled protein samples that is provided by rapid scan EPR will …

Astronaut Extravehicular Activity : safety, injury & countermeasures; &, Orbital collisions & space debris : incidence, impact & international policy
… In extreme cases these injuries lead to fingernail delamination (onycholysis) or rotator cuff tears and require medical or surgical intervention. In an effort to better understand the causal mechanisms of injury, a study consisting of modeling, statistical and experimental analyses was …

Abiotic Factors Contributing to the Survival of Three Tick Species in Southeastern Virginia, <i>Amblyomma Americanum</i> (Lone Star Tick), <i>Dermacentor Variabilis</i> (American Dog Tick), and <i>Amblyomma Maculatum</i> (Gulf Coast Tick)
… <p>CMR ticks were captured on flags, marked with fingernail polish, and returned to the location of capture. <em>Amblyomma americanum</em> was the dominant species collected (95% in 2014, 87% in 2015) when compared to the other tick species collected: <em>D. variabilis</em>, <em>A. maculatum</em>, …

A noninvasive, image-based smartphone app for diagnosing anemia
… Here, a patient simply takes a picture of their fingernail beds using their smartphone, and the image analysis algorithm analyzes color data and image metadata to measure the corresponding Hgb level. By quantifying clinical pallor, this system non-invasively measures Hgb levels to within a …

Relationships Among Aquatic Macroinvertebrates, Endangered Waterbirds, and Macrophytes in Taro Lo'I At Hanalei National Wildlife Refuge, Kauai, Hawaii
… Oligochaeta (aquatic worms), Sphaeriidae (fingernail clams), and Thiaridae (thiarid snails) were the most prolific invertebrate taxa among taro loi in sweep net samples in 2005. Freshly flooded loi during and recently after planting are dominated by chironomids and oligochaetes, shifting to …
