Effect of the Side Walls of a Shuttle on the Tension of Weft Withdrawn from the Shuttle

open access: yesJournal of the Textile Machinery Society of Japan, 1958
Tension withdrawn from a shuttle is affected by the number of winds per traverse, by the hardness of the yarn layers, by the length and location of the pirn, by the eyelet of the shuttle, by the velocity of withdrawal from the shuttle and by the side walls of the shuttle.

Boron Nitride Nanotube-Based Separator for High-Performance Lithium-Sulfur Batteries

open access: yesNanomaterials, 2021
To prevent global warming, ESS development is in progress along with the development of electric vehicles and renewable energy. However, the state-of-the-art technology, i.e., lithium-ion batteries, has reached its limitation, and thus the need for high ...

The Effect of the Side Walls of the Shuttle on the Tension of the Weft withdrawn from the Shuttle

open access: yesJournal of the Textile Machinary Society, 1957
研究目的緯糸解舒時の張力は, ワインド数, 糸層の硬さ, 木管の長さ, 部位, シヤットルのアイレット, 解舒速度, シヤットル側壁等に影響されるが, この中でバルーニングによる影響とシヤットル側壁の影響を区別して調べてみた.研究結果解舒速度が増加する程バルーニングによる張力は増加するはずで.側壁が全くなければ速度の2乗に比例するはずと思われるが, 実験結果はそれよりも常に小さな値となり, 側壁による摩擦の影響の方が遙かに大きいことがわかった.

Effect of deworming on school-aged children's physical fitness, cognition and clinical parameters in a malaria-helminth co-endemic area of Côte d'Ivoire [PDF]

open access: yes, 2014
Malaria and helminth infections are thought to negatively affect children's nutritional status and to impair their physical and cognitive development. Yet, the current evidence-base is weak.

Observation of heat pumping effect by radiative shuttling

open access: yesNature Communications
AbstractHeat shuttling phenomenon is characterized by the presence of a non-zero heat flow between two bodies without net thermal bias on average. It was initially predicted in the context of nonlinear heat conduction within atomic lattices coupled to two time-oscillating thermostats.

Three-Dimensional Honeycomb-Like Carbon as Sulfur Host for Sodium–Sulfur Batteries without the Shuttle Effect

open access: yes, 2022
Sodium-sulfur batteries operating at ambient temperature are being extensively studied because of the high theoretical capacity and abundant resources, yet the long-chain polysulfides’ shuttle effect causes poor cycling performance of Na–S batteries.
