為了找出電池消耗電量超過五成時，電池的恢復係數會有劇烈變化之原因，本組將電池解剖，觀察內部構造，並將電池中央挖空填入塑鋼土，模擬電池內部物質硬化結塊對電池彈跳之影響，並進一步使用玻璃瓶填充不同比例的砂-水混合物進行彈跳模擬。 經一連串的實驗設計可知，新舊電池內部構造截然不同，而造成彈跳性質變化：1、新電池底部有一空腔，充滿電解液，在撞擊時具有緩衝效果；2、新電池中央隔離層包覆的負極物質是柔軟的，會吸收反彈之能量；3、新電池的正極是固液混合物質，隨電池放電，會逐漸結塊硬化，當達到一定比例時，電池便會跳得更高。最終，根據電池彈跳性質差異，利用其撞擊時所發出之聲響，來迅速判斷電池新舊，此為一重大發現。

BCH (Bnip-2 and Cdc42GAP homology) domains are a novel class of protein-interacting domains. First identified in BNIP2 and in Cdc42GAP, a GTPaseactivating-protein (GAP), canonical BCH domains play important and varied roles in the control of cell morphology and apoptosis induction, amongst others. However, this domain is currently classified under lipid-interacting sec14 domains due to low sequence identity (~20%). Given this intriguing similarity, the relationship between BCH and sec14 domains is worth further study. As BCH/sec14 domains are closely associated with cell signaling and human disease, characterization of these domains and the elucidation of their functional diversity could better aid our understanding of their cellular functions and disease pathogenesis.

上課時老師以過去本校用保麗龍球內裝磁鐵所製成之模型來說明低限能，活化複體，催化劑效應，碰撞方向性等現象，當時我們連想到，化學上陰電性之意義與磁力之意義很類似；是否能以類似模型來解釋由於原子陰電性大小不同關係所引起之各種不同現象，於是在老師指導下製作這套模型。

在國中翰林版自然第五冊第二章的內容中，有介紹力的平衡觀念，而落下的雨滴是最好的例子，對於雨滴的各種現象充滿好奇，因此設計一連串的實驗，首先是不同直徑液滴的分裂探討，我們發現液滴越大其終端速度也越快，也會比較容易分裂。之後，我們進行不同液體表面張力的實驗，得知表面張力越小時液滴越容易分裂。\r 我們用滴管可以製造出直徑較大的水滴，但是自然界的雨滴卻無法達到這種大小，此極限值與雨滴的終端速度有關，當雨滴分裂的臨界速度小於終端速度時，雨滴就會分裂，當雨滴分裂的臨界速度接近終端速度時，雨滴正處於是否分裂的臨界點，因此我們認為此時雨滴的直徑，就是自然界雨滴的最大值，根據我們實驗的結果：其最大值約在6.1mm 到6.9mm 之間。

日常我們看到小石子、瓦片……等由高處落下時，速度越落越快，到底那樣快的速度，變化的情形怎樣？能不能測量？我們把這個問題請教老師，老師說：「由於自由落體加速度很快，要直接測量相當困難，一般都是利用閃光照相裝置、或是利用電鈴型計時器測量，但這兩種方法都有缺點」。我們聽了以後覺得既然這兩種方法有缺點，那塵我們能不能設計一套新的裝置來改良其缺點呢？因此我們做了以下的實驗。

The time is changeable between 1-99 seconds. Also there are four square lights fitted with the main counter to illuminate the colors. Auto Traffic detector. There are three sets of switches in front of each traffic light to detect if the road is clear for the cars to enter the next road. Red light crosser detector. After the signal become red this system will operate to detect any car try to cross the red light by the car cutting the switch two times.

本研究的目的在探討數種水果分解?，對萃取洋蔥 DNA 的影響，想了解在什麼情況下，哪一種水果分解?的反應最快。研究結果發現：實驗所選水果都含分解?，以火龍果汁分解?反應最快。沒有加火龍果汁分解?的洋蔥溶液，加入酒精後一樣會分層出像 DNA 的白色棉絮團狀物，但分層時間長，超過 15 分鐘以上；而加入火龍果汁後，反應時間明顯會增快，快至 30 到 40 秒內完成，可知火龍果汁分解?有催化作用。在火龍果汁的量方面，由 0%逐步加到 20%時，以 10%反應時間就達到極限，再增加單位果汁量並沒有顯著差異。在不同溫度的火龍果汁方面，除了常溫(22.5℃)外，冷凍(-10℃)、冷藏(4.2℃)和加溫(42.9℃)反應時間都變慢，這是因為每一種?都有一個反應最佳的溫度，溫度太低，?的活性會降低，溫度太高?可能會變性失去催化作用。本研究用的火龍果分解?在常溫下的反應最快。更進一步的研究發現，以最不易被萃取 DNA 的鳳梨當分解?，萃取火龍果種子的 DNA 時，可以萃取到較純又多的火龍果 DNA。

Table tennis the fastest ball sport in the world has become so fast that rallies have become\r very short. My investigation this year is a further study into slowing the game down. Last\r year I studied the effects the newly introduced 2mm larger ball had on the game. I\r concluded an average increase in rally length from 2.93 to 3.47 balls per rally passing the\r net. Although a 16% increase sounds large, it was an average of less than 1 ball per rally\r difference. I came up with another way to slow the game down my aim was to find out if\r increasing a table tennis net height will decrease spin, speed and increase control i.e. rally\r length and to find out what percentage extent each height level has on these factors. I\r wanted to be able to present a finding as to the optimum net height for the percentage\r increase in rally length that is desired.

1. Purpose of the research Because we live in a famous winter sport region in Switzerland, we have been confronted with the problematic of avalanches since we were born. In winter 2011/2012 alone, 179 people were involved in an avalanche accident, of whom 25 died. The most important device for searching and rescuing a buried person is the avalanche transceiver. It creates an electromagnetic field, which can be used to locate a buried person with another transceiver. The most important factor while searching is time: After 30 min. the chance of survival of a buried person has dropped to 40%. Considering the fact that people often make mistakes when they are put under such a big stress, valuable time gets lost. This is where our project comes into play. With an automation of the searching process a fast and reliable search should be achieved. The aim we agreed on for this paper is to develop a prototype of a robot that can find an avalanche transceiver automatically and reliably. To study and optimize the functionality of our robot more easily, our tests have only been performed on flat ground. 2. Procedures The components of an avalanche transceiver with only one transmitting antenna are used as a receiver. With the help of this receiver, the signal of a transmitting avalanche transceiver was analysed. Furthermore, the results were used to evaluate the most suitable search technique. Our robot is based on the “RP6” robot system, which is programmable in the C-language. The signal of the receiver is modified in a way which allows the robot to read it. Based on the results of the signal analysis, a search algorithm is developed. In the final tests the robot was examined as to its functionality and efficiency. Therefore, the robot was positioned at randomly chosen starting points to locate the transmitting device. 3. Data The transmitter could be located correctly in every test. The starting points were successfully located up to 11 m from the transmitter. The search ending points were found at a maximum range of 0.5 m from the correct position. 4. Conclusions In view of the results, the aim of developing an automatic localisation of an avalanche transceiver on flat ground as a prototype is seen as fulfilled. Outside the specified range, the transmitter can only be located unreliably. This is due to the fact that outside that range the signal differential in different directions is too small to be processed by the robot. Our prototype was tested under ideal conditions. Certainly, our robot is still some way from being ready for use in an actual avalanche. Many different questions have not been answered yet or have come up during this project, for example: ‘How should the robot should be applied on uneven terrain?’ or: ‘How should it deal with several buried people at once (multiple transmitted signals)?’ Two aspects of our prototype, the low weight and the low construction costs, however, are particularly favourable.
