On the High Speed Windes

Journal of the Textile Machinary Society, 1950
研究目的1. 巻返機の綾振装置について、綾振差、綾振端硬化、振動の発生、綾振並に巻取糸速の変動、摩擦、密度斑等の諸因子間の関係を求めた。2. 各途返機の基本的特性について論じ、プリサイズ巻を生産対象とするカム綾振糸道型巻返機と、レギユラー巻を生産対象とする溝付綾振転子を主流としてとりあげた。3. コーン巻において基本となるべき一般綾振曲線を解析した。研究結果1.非対照形綾振曲線が色々な意味において優つている。2. カム並にローラの形式の改善によりカム綾振糸道巻返機の能牽は向上された。3. レギュラーコーン巻に用いる基本綾振曲線としては、二次曲線が用いられ、これを非対照形として、溝交叉部における綾振を安定させると共に、溝と糸との運動方程式 (62) 式より溝傾斜角、溝深さ、糸の交叉角、綾振幅 ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

High-Speed Electrochemical Imaging [PDF]

ACS Nano, 2015
The design, development, and application of high-speed scanning electrochemical probe microscopy is reported. The approach allows the acquisition of a series of high-resolution images (typically 1000 pixels μm(-2)) at rates approaching 4 seconds per frame, while collecting up to 8000 image pixels per second, about 1000 times faster than typical imaging

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
