National Geographic Readers: Animal Tails (L1/Co-Reader)

為了解決A ball的問題，作者Davidson, Rose 這樣論述：

Why do animals have tails? Parents and kids together will discover unique animals and learn all the cool ways their tails help them move, communicate, and keep safe. This Level 1 Co-Reader takes readers around the world to meet some kid-favorite and new creatures whose tails have remarkable abili

ties. Learn how dolphins use their powerful fins to swim up the Amazon River, why a pangolin uses its scaly tail to curl into a ball, and how a mom and baby spider monkey swing from tree to tree with a fluffy long tail! Each page will dazzle and delight with new and familiar creatures and amazing fa

cts. Fun activity pages allow parents and kids to engage with the content even more while also building their vocabulary. National Geographic Kids Readers have been a hit in the beginning reader category, and this book builds upon that success with a different approach--parents and children reading

together. With the same combination of careful text, brilliant photographs, and fun approach to high-interest subjects that has proved to be a winning formula with kids, National Geographic Co-readers provide one page of adult read-aloud and one page of kid read-aloud text on each spread, building t

oward a collaborative reading experience. So come along for a tale of animal tails and learn what makes them so special!

利用焙燒暨酸浸法從廢棄LED晶粒中回收鎵金屬資源

為了解決A ball的問題，作者吳德懷 這樣論述：

LED是發光二極體(Light Emitting Diode)的簡稱。由於LED燈具有節能、無汞等特性，在照明市場之需求日益增加，LED在許多領域已經取代了傳統光源(白熾燈、螢光燈等)。LED燈之高效率白光照明主要是由LED晶粒中氮化鎵(GaN)半導體所產生。隨著LED市場的擴大，未來將產生大量的LED廢棄物。因此，回收廢棄LED中所含的鎵金屬資源對於資源的可持續利用和環境保護都具有重要意義。本研究以廢棄LED燈珠為對象，利用焙燒與酸浸法從其LED晶粒中回收鎵金屬資源，主要包括三個部分：化學組成分析、氟化鈉焙燒處理與酸溶浸漬等。探討各項實驗因子包括焙燒溫度、焙燒時間、礦鹼比、酸浸漬種類及濃度

、浸漬時間、及浸漬固液比等，對於鎵金屬浸漬率之影響，並與各文獻方法所得到的鎵金屬浸漬效果進行比較。研究結果顯示，LED晶粒中含有鎵5.21 wt.%，氟化鈉焙燒暨酸溶浸漬之最佳條件為焙燒溫度900 ℃、焙燒時間3hr、礦鹼比1:6.95、鹽酸浸漬濃度0.5 M、浸漬溫度25 ℃、浸漬時間10mins、固液比2.86 g/L，鎵金屬浸漬率為98.4%。與各文獻方法相比較，本方法可於相對低溫且常壓下獲得較高之鎵金屬浸漬效果。

G. Gregory Haff, PhD, CSCS, *D, FNSCA, is an associate professor and the course coordinator for the postgraduate degree in strength and conditioning at Edith Cowan University in Joondalup, Australia. Haff has published more than 80 articles, centering his research on performance effects in the area

s of strength training, cycling, and nutritional supplementation. Haff is the president of the National Strength and Conditioning Association (NSCA) and a senior associate editor for the Journal of Strength and Conditioning Research. He was the United Kingdom Strength and Conditioning Association (

UKSCA) Strength and Conditioning Coach of the Year for Education and Research and the 2011 NSCA William J. Kraemer Outstanding Sport Scientist Award winner. He is a certified strength and conditioning specialist with distinction, a UKSCA-accredited strength and conditioning coach (ASCC), and an accr

edited Australian Strength and Conditioning Association level 2 strength and conditioning coach. Additionally, Haff is a national-level weightlifting coach in the United States and Australia. He serves as a consultant for numerous sporting bodies, including teams in the Australian Football League,

Australian Rugby Union, Australian Basketball Association, and National Football League. Charles Dumke, PhD, is a full professor in the department of health and human performance at the University of Montana, where he teaches undergraduate and graduate courses. He has taught courses in exercise phys

iology for over 15 years, first at Appalachian State University and then at the University of Montana. He earned his doctoral degree in kinesiology from the University of Wisconsin at Madison. His areas of interest in exercise science are energy expenditure, fuel utilization, economy of movement, me

chanisms of mitochondrial adaptation, and diabetes. He has published more than 100 peer-reviewed articles on these topics. Dumke is a fellow of the ACSM and serves on several national and regional committees. In his free time, Dumke enjoys competing in triathlons, biking, running, taking on buildin

g projects with little know-how, and coaching his son in ball sports. He resides in Missoula, Montana, with his wife, Shannon; son, Carter; and dog, Rastro.

羽球視覺訓練系統建構與測試

為了解決A ball的問題，作者侯展承 這樣論述：

　　目的：現今羽球教練訓練選手大多透過多球訓練或選手多打一的方式來提升選手各在羽球方面技術的能力。為能幫助教練及選手進行更簡單且有效的訓練，本研究以運動視覺為依據，研發一套可在羽球的專項多球訓練中，模擬擊球目標區、對手站位及實際比賽情境之視覺訓練裝置。訓練裝置主要元件為1組LED燈控制盒及6盞LED燈。　　方法：本研究以高中青少年羽球單打選手為研究對象（實驗組N=16，控制組N=16），實驗組透過此羽球視覺訓練系統介入訓練後，再以ATHLEVISION運動視覺檢測軟體（ASICS Corporation, Japan）進行檢測，再將所得之資料以混合設計二因子變異數分析（mixed desig

n tow-way ANOVA）進行考驗，若交互作用有顯著，則以單純主要效果進一步考驗。　　結果：結果發現實驗組之選手經介入訓練後，在各項運動視覺能力檢測中，在動態視覺銳度-下、眼球運動、周邊視野與瞬間視覺結果皆呈現顯著的訓練成效。
