我們一般所使用的日曆，多採用紙質，一天撕去一頁，十分不方便，且不夠美觀；而我們所使用的時鐘，皆為指針式，誤差大，不夠準確，不易讀，且易生故障；針對這些缺點，若我們能用電子方式，以數字直接指示時問，並使數字發光，則其準確性及易讀性之改善，足可將舊式時鐘加以淘汰；另外，日曆亦可由時鐘加以控制，所有日期、月份、星期，皆以發光數字顯示，且能自動換頁，不須動手操作；因而裝此時鐘及日曆合併為一可完全免除舊式時鐘及日曆的缺點，完成一新型之「日曆鐘」

某日，在書上看到許多有關植物莖葉的特性，其中包含有屈光性與背地性，心想，此兩種變因均為影興植物莖系的指向運動，在一般正常情況下，光與地為來自不同之兩個方向，但若來自同一方向，植物的生長會如何？是背地性大，還是屈光性大？抑或是會做某種程度的協調？其中真象如何？由於找了許多書籍，都無法給我一個滿意的答案，於是就親自著手設計這實驗。

自從高三接觸到地球科學後，深覺鄉上環境與居民生活息息相關，休戚與共的，所以環境品質之優劣，為值得重視的課題。近年來，高雄市快速成長，雖成為全省首屈一指的工業都市，卻使市場居住的生活環境受到文明副產物之嚴重污染，其中以水污染產生的害處，對市民生活構成很大威脅。根據最近之報章雜誌報導中，顯示高雄地區河川，以後勁溪水質污染負荷量最為嚴重，身為高雄市民的一分子，對自己生長的鄉土，應付予積極關懷，囚此我們乃利用寒假課餘時間，對後勁溪水質污染情形，作實地調查研究，期能喚起大眾正視水污染問題，共同維護純潔水質，為創造更潔淨，美好的明天而努力！

我家附近水溝每年都要清，濁水溪真有這麼濁嗎？是否濁水帶來淤泥？還是只有我們家是這樣的？我們學校前的莿子埤圳，河水混濁但卻看不見淤積的泥沙，到底是甚麼原因造成的？濁水溪中下游的主流裡的溪水是否也是這樣？要怎麼測量濁度呢？我們想研究濁水溪的「濁」度及如何測量。於是蒐集濁水溪及附近的溪水和泥沙回來做實驗。結果發現：一、西畔分校泥沙減重多含水高。溪州大橋及水里龍神橋都是細沙蒸散快。二、雨後的水含沙量高，水較濁。梅雨季含沙量均提高。三、【一】灑水泥沙向外擴散，西畔分校的泥塊堅硬土質不同。【二】灌溉溝渠之泥沙小而黏稠，易結塊，懸浮物造成混濁。主流顆粒大。【三】坡度越高，易將泥沙、石塊帶走；沖的時間久，易被沖走；顆粒小易被帶走。四、透光率最低是彰雲大橋，次是岸角牌樓。梅雨後透光率皆低。流動的水透光率低濁度高。水里街上的岩層不同，泥沙少，濁度低。五、主流雨後較清澈，而灌溉溝渠雨前較清澈。雨後則濁度變高，透視度變低；主流雨後稀釋，泥沙量變多，透視度高。六、多處透視深度可達13cm，三處約3-4cm。雨後：僅岸角田變濁，其他透視度仍深。梅雨季後：水變濁，透視度2㎝以下。七、直射與散射發電量呈反比。濁度高：光線穿透少，直射線發電量低，散射多，90度角發電量高，可量化測量。八、濁度高浮標下沉深；濁度低浮標下沉淺。與原先濁度高，浮標上浮的假設相反。九、流速快，濁度高，流速慢，濁度低。靜止時濁度最低。十、西畔分校與集集攔河堰有非土壤有機質。顆粒大小以溪州大橋最大、而水里工程與水里街上無懸浮顆粒，與濁度實驗相同。

科技並非一朝一夕而成，許多科技和發明都是經年累月，所產生的。追溯到春秋時代魯國的工匠發明家魯班，其發明中最為人稱奇的便是木馬車。木馬車乃運用現今稱之為「連桿機構原理」所製作成類似馬匹行走的機構。連桿原理是依據所需之運動位移，設計出連桿組以達成預期的拘束運動。連桿裝置運用在現今的機構上是相當普遍的，例如腳踏縫紉機和腳踏車的曲柄搖桿、摺布機和汽車雨刷的雙搖桿、汽缸的曲柄滑塊、碎石機的肘節機構… … 等．皆是利用連桿原理組成的各式機構。故依魯班木馬車之原型，運用連桿原理融入新的創思改良，使機械馬不需依附拖車，就可以四足獨立行走，追求更擬真馬的行走狀態。

本研究主要探討菠菜、萵苣、A 菜在壤土、泥炭土、混合唐山石之泥炭土等三種有機栽培介質中的生長情形。研究結果有四點發現(1)菠菜在三種栽培介質中，尤其是在混合唐山石的泥炭土中，生長情形最佳；(2)萵苣在三種栽培介質中，尤其是在混合唐山石的泥炭土中，生長情形最佳；(3)A 菜在三種栽培介質中，尤其是在混合唐山石的泥炭土中，生長情形最佳；(4)在有機栽培蔬菜條件，同樣的控制變因之下，三種蔬菜在混合唐山石的泥炭土中，生長情形是最好的。研究者也依這四項發現，對壤土、泥炭土、混合唐山石之泥炭土等三種有機栽培介質之孔隙度、滲水性、涵水性、酸鹼性做更深入的研究。研究結果發現，蔬菜在三種栽培介質中，以混有唐山石之泥炭土介質生長的最好，其主要的原因是唐山石具有孔隙度最大、滲水性最佳、涵水性也最好、呈中性的特性。

Farmers in many countries are legally required to identify livestock with some sort of tagging system. Tagging is required for ownership, breeding and as a means of tracking livestock during a disease outbreak.\r New Zealand farmers are required to fit all livestock with two ear tags (one in each ear). Ear tags are applied in a similar way to the piercing of human ears. The two tags are of different sizes and are known as the primary and the secondary tags. The primary tag is physically bigger than the secondary tag.\r We farm deer and have noticed that after tagging some deer develop ear infections at the site of tagging.\r A randomized controlled trial was undertaken in 105 fawns to test the hypotheses:\r ‧ Pre treatment of the ear tag with liquid iodine will reduce post tagging infection.\r ‧ A reduction in ear infections as a result of tagging will lead to more rapid weight gain.\r The treatment group had iodine applied to the sharp part of both primary and secondary tags immediately prior to tagging of the fawns. The control group was tagged in the usual fashion. Fawns were then assessed for infection at 6 and 11 weeks after tagging. Each ear was individually graded for infection and recorded against the number of the animal. Grading was on a scale of 0-3: zero having no infection; 1-slight redness; 2-a larger ring of redness and possibly some dried blood; 3-as for grade 2 plus swelling of the ear around the pin.

Synthesis of halooximes has attracted much attention given their importance as precursors to proline derivatives1, unnatural amino acids2 and a host of alkaloids3. Halooximes have numerous industrial and biological applications 4, for example oxime ethers increases specific channel opening activities, acting as potential targets in drug treatment for various diseases 5, most adrenergic β-receptor blocking compounds also conform to the structure of oxime ethers 6. They also have vitro antifungal activities against certain plants7. A known method for the synthesis of 3 using Me3SiX as a Lewis acid, via intermediate enamines with acyclic/ cyclic bis(oxy)enamines, gives yields between 21-68%. Low yield stems from lack of reaction specificity2. In this work, we investigate coupling nitrogen-oxides with CoBr2 to synthesise halooximes in high yield. Initial cyclic/ acyclic bis(oxy)enamines were prepared by reacting 1 equiv. nitro compound with 2.4 equiv. in excess of dichloromethane under argon atmosphere at a temperature of 0ºC. 2.2 equiv. of TMS-Br was further added and left to stir till thermal equilibrium with room conditions. The cyclic/ acyclic bis(oxy)enamine was isolated upon aqueous work-up, filtration and evaporation. Synthesis of halooximes was carried out by reacting 8mL to 1mmol equiv. of THF and 2 equiv. of CoBr2 under argon atmosphere and left to stir till CoBr2 dissolves. 2mL to 1mmol equiv. of CH2Cl2 was added to 1 equiv. of bis(oxy)enamines. The reaction mixture was left to stir at room temperature for 2 hours, after which aqueous work-up, filtration and evaporation were carried out. Our results are summarized in Table 1. We also obtained relatively high percentage yields for the direct synthesis of bromooximes from cyclic nitronates via a one-pot procedure: Low yield stems from lack of reaction specificity2.

我家後面右一塊地勢較為低窪的空地，一直未被利用，幾年來都被當作污泥，穢物的堆積所，以致於雜草蔓生。直到去年夏天，不知何處運夾一大批的泥土，（我想八成是河底剛挖起來的）掩埋了大半的空地，從此再也長不出雜草了。我當時覺得很奇怪，首先懷疑是不是泥土的土質問題，後來經過觀察和比較，發現土質並非主要因素於是就跟幾位志同道合的同學開始查書，請教老師，終於引出了跟植物生長關係最為密切的”土壤酸鹼度問題”並且展開對蘭陽溪以南地區土壤酸鹼度的性質做了一番淺略而有系統的調查實驗。
