RAF Helicopters of the 1970s and ’80s

為了解決puma的問題，作者 這樣論述：

This is the fifth book in the series of photographs of British combat aircraft of the 1970s and 1980s and covers the RAF helicopters in service during those two decades and their part in the latter stages of the Cold War. The Westland Whirlwind was used in the air-sea rescue (ASR) role before bei

ng replaced by the Westland Sea King, both aircraft being prominent around the British coastline with their bright yellow coloring. The Westland Wessex was used by the RAF in a variety of roles including search and rescue. The Aérospatiale Puma was introduced to service with the RAF in 1968 and is s

till being flown today while the Boeing Chinook came into service in 1981, just in time to take part in the Falklands War, and is still in service today. Containing 180 photographs, this book is a pictorial compendium of these iconic machines.

以自動相機估計中台灣石虎族群密度

為了解決puma的問題，作者顏全佑 這樣論述：

石虎（Prionailurus bengalensis）為野生動物保育法所公告之瀕臨絕種保育類野生動物，由於石虎實際族群密度資料的缺乏，難以準確估算全島石虎族群量。本研究在南投縣中寮鄉設置後寮及龍眼林等兩個各30 km2的樣區，每個樣區各有30個1 km2網格並設立1樣點，每個樣點架設兩部紅外線自動相機進行拍照及個體辨識，主要目的有四：(一)利用捕捉-再捕捉法估算兩個樣區之石虎密度；(二)評估每個樣點兩台相機比一台相機在石虎密度估計上的成效；(三)探討每個相機樣點的石虎出現頻度指數(Occurrence Index, OI)是否可反映在該樣點出沒的個體數；(四)探討電腦輔助軟體-Hotspo

tter在石虎個體辨識的應用性。結果顯示，在後寮樣區分別以非空間直觀捕捉-再捕捉法(Non-spatial capture–recapture methods, CR)及以空間直觀捕捉-再捕捉法(Spatially explicit capture–recapture methods, SECR)所估計的石虎族群密度分別為每100 km2 有55隻及49隻；龍眼林樣區分別以CR法及SECR法估計的密度為每100 km2有57.5隻及41.9隻。使用兩台自動相機之照片比起使用單一相機照片，石虎密度於後寮及龍眼林樣區分別提升11.5%及77.2%。兩個樣區內不同樣點OI值與石虎辨識量皆呈現顯著正相

關，相關係數分別為0.772及0.878。本研究發現電腦輔助軟體-Hotspotter能提供研究人員進行個體辨識之參考，但無法完全取代以人工進行個體辨識。

The Metamorphosis

為了解決puma的問題，作者Brandis, Katja 這樣論述：

A wonderful new middle grade series in shapeshifting genre!At first glance, Carag looks like a normal boy. But behind his shining eyes hides a secret: Carag is a puma shapeshifter and has only recently started living in the human world. Half human, half mountain lion, Carag grew up in the wilderness

of the Rocky Mountains. He can’t help but wonder what life as a human would be like even though his curiosity divides him with his family of mountain lions and puts him in great danger. When he finds out about a secret boarding school for Woodwalkers like him, that he felt a sense of home. He makes

friends in Holly, a cheeky red squirrel, and Brandon, a shy bison. And Carag can really use it - because the world of Woodwalkers is full of puzzles and dangers...

製備適用模擬太陽光之氧化鉍/蒙脫石/二氧化鈦光觸媒降解揮發性有機物1,2-二氯乙烷之研究

為了解決puma的問題，作者郭憲治 這樣論述：

本研究藉由蒙脫石摻雜於二氧化鈦製備不同比例之蒙脫石/二氧化鈦固定式光觸媒(MT)；透過UV-Vis、FE-SEM、XRD、XPS及FT-IR進行物理性質分析；並探討不同比例光觸媒於無氧環境之批次實驗系統以模擬太陽光/紫外光照射降解1-2,二氯乙烷成效；且探討於最佳成效MT光觸媒中加入氧化鉍製備氧化鉍/蒙脫石/二氧化鈦光觸媒(BMT)之成效。UV-Vis顯示BMT光觸媒皆具兩處吸收波長，且其中一處位於可見光波段；SEM顯示光觸媒表面無明顯變化且存在蒙脫石；XRD顯示光觸媒同時具銳鈦礦及金紅石晶相，且未觀察到其他雜質；XPS顯示MT光觸媒具Ti2p3/2及Ti2p1/2及Si2p元素，且BMT光

觸媒具有Bi2p7/2及Bi2p5/2元素；FT-IR顯示光觸媒具Ti-O、Ti-O-Ti、H-O-H、-OH官能基，綜合上述顯示成功製備改質光觸媒。由模擬太陽光光催化實驗結果顯示0.5BMT#(含有0.5 mol%氧化鉍及5 mol%蒙脫石之二氧化鈦)效果最佳，於135分鐘可達100.0%降解；紫外光光催化實驗結果顯示5MT#(含有5 mol%蒙脫石之二氧化鈦)效果最佳，於模擬太陽光照射下於97.5分鐘可達100.0%降解。經反應動力學推估，本研究模擬太陽光光催化實驗較符合一階反應模式；經耐久性實驗(連續五次光催化實驗)後，0.5BMT#仍維持80.9%降解率，表示具良好重複利用性；且由FT

-IR分析光催化產物顯示無明顯有毒副產物產生。綜合上述，本研究所製備之光觸媒於模擬太陽光可有效降解目標污染物1,2-二氯乙烷。
