同步現象的研究
In our daily life, objects and the contacts between objects they will have mutually affect each other, some initially chaotic systems after a sufficient amount of time will mutually correct each other, and finally achieve synchronization (example: the speed of bird and fish migration, market prices, infantry…), although some are unable to achieve this. We will illustrate and explain the synchronization system, its process and discover the conditions for synchronization. Using linking concepts, we will integrate the coupled map lattices with global coupling and coupled map lattices with intermediate-range models into a synchronization mode in order to simulate a synchronization system. We first used a small system of n≦50 to obtain results that will demonstrate the linking concepts: 1. The more chaotic a system, a longer period of time is required for synchronization. 2. An increase in the number of individual objects requires an increase in the range of concepts and the amount of time in order to achieve an in depth synchronization. 3. Initial concept values which randomly effect synchronization critical point conditions are not obvious in a mathematically incorrect graph. In a closer look, when we increased the synchronization to n≦400 and the number of times to t-->100,000 we discovered:1. Using the function G(x) we hoped the results from the graph after apply the function and correction able to overlap and test with “Scaling and Universality in Transition to Synchronous Chaos with Local-Global Interactions”, but the part which overlapped the measurements was not identical: 2. We can use the significance of the critical point and the Interactive Process to find the approximate value of the critical value up to 4 digits following the decimal point. 3. We can also use the approximate value to find out the range for the simultaneous conditions and the various points on the system itself, as well as obtain a negative correlation between them, and then it can be similarly expressed with using a curve. A computer can calculate values with this kind of enumerating method, even without any special resolution capabilities to quickly obtain large amounts of approximate values of simultaneous conditions, this is especially true when calculating unfamiliar systems. 日常生活中，物件與物件的接觸，彼此會互相影響，有些原本雜亂的系統再經過充裕時間的互相修正後，最後竟能達成同步(例如：鳥群、魚群遷徙的速度、市場價格、行軍步伐…)，有些則不能。因此，我們試著利用描述同步系統的模型，觀察系統同步的過程，並且找出同步的條件。由連結的觀點，我們將Coupled map lattices with global coupling 和Coupled map lattices with intermediate-range 模型的優點整合成Synchronization mode 去模擬同步系統。我們先用小系統(n≦50)得到能印證連結觀點的結果：(一)、系統越雜亂，就需要稍長的時間同步；(二)、個體數越多時，各點需要更大範圍的點數去影響於每單位時間內以及更深的影響才能同步；(三)、起始值隨機影響同步臨界條件並不明顯，在誤差範圍內。更進一步，我們將系統推向n≦400 點,t→100,000 次，我們發現：(一)、在”G(x)”我們希望能將圖形經過函數修正之後能疊和，驗證”Scaling and Universality In Transition to Synchronous Chaos with Local-Global Interactions ”中的結果，但只有部分疊和，尺度不相同；(二)、可以直接利用臨界點的意義用十分逼近法求出臨界值的近似值到小數後四位；(三)、我們用近似值也能發現同步條件與系統各點本身可跳躍的數值範圍是負相關，可用曲線去近似。這種窮舉方式，交由電腦運算，不需要特別的解析能力就能夠快速且大量求得同步條件的近似值，尤其在運算不熟悉的系統時。
線蟲捕捉菌Arthrobotrys musiformis 調控捕捉網之分化及其黏液之基因之選殖和特性界定
Nematophagous fungi can form different kind of trapping device to trap the nematodes when they show off. They may play a role for control of the plant and animal parasitic nematodes as an alterative choice beside regular practice. We attempt to investigate the adhesive’s attributes and the genes that encode trapping structures. Now we have already constructed the Arthrobotrys musiformis Fosmid library which will play a vital resource for specific genes analysis, cloning and characterization in the future. We have chosen two genes encoding protease and superoxide dismutase from Arthrobotrys musiformis, respectively, and will be used as probes to screen the Fosmid library. The relevent clone(s) will be subject to restrictive enzyme disection, Southern blotting or even whole Fosmid 40kb DNA fragment sequencing to discover the interesting and paramount genes. 線蟲捕捉菌在線蟲出現時可以產生型態各異的捕捉構造，捕捉或黏著線蟲。它是防治線蟲的另類選擇。本實驗是由生物的分生觀點切入，希望能夠了解線蟲捕捉菌Arthroborys musiformis於捕捉網表面之黏液生化特性以及控制產生捕捉構造的基因。目前已完成建 Arthrobotrys musiformis之Fosmid library，並且選擇兩組探針：蛋白質?(protease)以及超歧氧化?(superoxide dismutase)，將以PCR進行基因探針之DIG標定，之後篩檢Fosmid library，選殖出相關clone，進行限制?切割，南方氏雜合特性分析或40kbDNA全序列分析，尋找相關基因以利下游實驗工作之進行。
Powerless Shack Cooler
Purpose of Project: To save energy and to help the underprivileged with a cooler that uses no electricity to make their lives better. Procedure/method followed: STEP 1: Collected 28, used, 2 litre plastic bottles. STEP 2: Chose the window with the best wind flow. Measured the size of the window and the room chosen. STEP 3: A sturdy thick polystyrene board was cut to the size of the window. Holes were drilled to the rim size of the bottles spacing them according to the body size of the bottles. STEP 4: Bottles were cut in half. STEP 5: The bottle necks were slid through the holes with the necks open to the inside of the room and the bodies open to the outside. STEP 6: Fixed a thermometer in the room and measured the temperature and recorded it. STEP 7: Fixed the Powerless Shack Cooler with the necks of the bottles open to the inside and the bodies open to the outside of the room. STEP 8: The temperature variation was checked and recorded every 30 minutes for 3 hours. STEP 9: Another room of the same size and window was also chosen. Fixed a thermometer and temperature variation was checked and recorded every 30 minutes for 3 hours. This served as the control of the experiment. Data/results: The room temperature decreased over time inside the room where the Powerless Shack Cooler was installed onto the window. But the control room maintained the initial room temperature although slight fluctuations in the room temperature were observed over time. Conclusion: The hypothesis was supported. As the air molecules moved through the bottles, it bounced off each other, and off the walls of the container, holding the air. A small volume of air passed at a high velocity. When the molecules moved faster the collision became more often. These collisions and the push increased air pressure. When the container’s space was getting smaller, the molecules picked up speed and the temperature went up. When the air was released out into the room, the volume suddenly expanded. The intermolecular spaces became larger; so less agitation and vibration of molecules took place. The molecules moved slowly. The room temperature reduced. Air inside the room became cooler. During the adiabatic expansion, air molecules used heat energy from the room and converted it into kinetic energy for faster movement.
口蹄疫病毒鞘蛋白rVP1 誘發Prohibitin 之遷移
細胞凋亡具有控制生物體細胞數目之功能，能讓特定的細胞走向死亡，因此若能掌握其作用機制，便可能藉由調控細胞凋亡的發生，進而應用於癌症治療。前人研究（2.）指出，經基因重組技術純化之口蹄疫病毒鞘蛋白rVP1，會導致BHK-21的Akt 蛋白質去活化，引起細胞凋亡的現象。然而在其後續的研究中，卻發現到在BHK-21中大量表現磷酸化的Akt 蛋白質，並無法反轉由rVP1 所誘發之細胞凋亡。因此本實驗利用二維蛋白質電泳，尋找Akt pathway 以外之細胞凋亡相關蛋白質。目前已證明Prohibitin 此一蛋白質，在由rVP1 所引起之細胞凋亡中，有自細胞核移動至細胞質的現象。此外，亦經由實驗排除Prohibitin 位於Akt pathway 的可能性。Western Blot 之結果更顯示，經rVP1 處理後，Prohibitin 在很短的時間內便出現遷移的現象，故推測其具有調控細胞凋亡上游反應的功能。Apoptosis can lead some specific cells to programmed death, thus, it is a major way for creatures to control their cells amounts. If we can command the mechanism of apoptosis, we may use it as a therapy for cancer by artificial regulation of apoptosis. VP1 is one of the capsid proteins of Foot and Mouth Disease Virus (FMDV). A research (2.) has indicated that the recombinant VP1 (rVP1) can result in dephosphorylation of Akt in BHK-21, and then lead the cells to apoptosis. However, in their follow-up experiments, they discovered that even if they expressed great amount of phospho-Akt in BHK-21, it still couldn’t reverse the apoptosis induced by rVP1. Therefore, this experiment takes the advantage of two-dimension protein electrophoresis (2D) in order to find apoptotic proteins excluded from the Akt pathway. I have found that Prohibitin exports from nucleus to cytosol after rVP1 treatment. Furthermore, I eliminate the possibility that Prohibitin’s may be located in Akt pathway. The results of Western Blot also shows that protein amount of Prohibitin in BHK-21 increase after rVP1 treatment, hence the purpose of nuclear export of Prohibitin might not be to degrade it. It might have some much more important function in the process of exportation. Besides, Prohibitin exports to cytosol in quite a short time after rVP1 treatment. According to this phenomenon, I suppose that Prohibitin has a role as a regulator of apoptotic up-stream reactions.
昆蟲模擬-雙振翅翼
本研究的目的在於探討蜻蜓兩對翅膀在不同的相位差之下對升力有什麼影響。在觀察蜻蜓及察閱相關網站、研究後發現蜻蜓前後翅的相為差有相差0.5 週期、相差0.25 週期、同週期三種不同振翅方式。在界定欲實驗的種類和評估現有的能力及資源後，決定研究加上相差為0.125 週期的四種振翅方式，於無風條件、相同的振翅頻率下進行實驗，測量其升力的變化週期。測量結果參照前人的文獻後發現，0.5週期產生的升力雖最小，但最平穩，所以為蜻蜓最常用的飛行方式。而0.25 週期升力會疊加，往下的力被抵銷，故為向上加速時使用。 ;The purpose of this study is to investigate the phase-shift between the front-pair and rear-pair wings on the maximum lift of a dragonfly. As observing the flight of a dragonfly and the literature survey from web sides, it has been observed that the general phase-shift modes of the dragonfly are in-phase-shift, 1/2 period and 1/4 period. It has been decided to include a 1/8 period phase-shift mode into the known three modes under the no wind condition with a fixed flapping frequency, the cyclic lift force of the dragonfly wing model has been measured. When it is flapping, we put the model on an electronic scale for measuring the weight of the model. After that we minus the original weight of the model, knowing the increasing or decreasing weight and the extra weight is the lift force. The results show that 1/2 period phase-shift mode produces the least lift force; however, it is the most stable flight, and is being adopted by the dragonfly for level flight. The in-phase-shift mode can produce more lift force on the flapping processes. The 1/4 period phase-shift mode produce the most acceleration, being adopted by the dragonfly for the climb flight.
整合型水族養殖系統研究與開發
本研究主要的目的是在開發二氧化碳製造、過濾與循環的整合型水族養殖系統。二氧化碳的產製是以基於發酵原理，並搭配具有純化二氧化碳作用的水濾裝置，發酵環境溫度以水族箱內的水來維持，循環過程中並搭配外部過濾器，所有容器均由保特瓶改裝完成，整合成一套價廉、環保且具有高效率的水族養殖系統。由實驗結果可得知，二砂糖發酵對於二氧化碳產生率而言，其最佳發酵環境溫度範圍25℃~35℃，一般水族箱的水溫即可保持在此一溫度範圍。過濾系統則使用光電比色計與一般市售過濾器相比較，亦有令人滿意的效果。本實驗除了研究以二砂糖發酵之外，還希望更進一步地朝向廚餘減量方面開發其他發酵材料，希望能為環保盡一份心力。;The purpose of this study is to develop an integrated system of aquatic breeding with the functions of producing carbon dioxide, filtering and circulating, where carbon dioxide is produced based on fermentative theorem and purified by the water filtering; the environmental temperature of fermentation is maintained by the water in the aquarium and circulating is through an external filter. All the containers are made of PET bottles and thus integrated a cheap, environmentally friendly and high efficient system of aquatic breeding. According to the experimental result, for the producing rate of carbon dioxide, the best fermentative temperature of NO.2 granulated sugar is 25℃~35℃. With a photocell colorimeter to compare the function of the self-made filter with that of the filters on the market, one can find it’s comparable. In addition to the fermentation of NO.2 granulated sugar, the study is also expected to develop other fermentative materials to reduce kitchen waste for environmental protection.
A Study For Heavy Metals Detection Using The Solubility change of Different Kinds Solute
A research on how a solution mixed with two or more solutes affect the solubility of each solute was done. If different solutes are put in a solution with a specific concentration, the solubility of the single state solute increases, stays the same, or decreases. The difference in solubility caused by several solutes will give solutions on selectively collecting heavy metals from bodies of water polluted by these heavy metals even more effectively. To test the changes in the solubility of the solution with several solutes, sedimentation has been used; however, colorimetric analysis was also done to observe the changes in color of solutes that show color in the solution. Nitrate compounds of Sodium, Magnesium, Strontium and Potassium were used for the typical metals, and for the transition metals, nitrate compounds of Silver, Cadmium and Lead were used. Test results show that Sodium decreased the solubility of Lead, and as the concentration of Sodium increased, the solubility of Lead increased too. On the other hand, K increased the solubility of Pb, and as the concentration of K increased, the solubility of Pb decreased. We can use the radius of ions and the enthalpy of hydration to explain the changes in solubility. In the case of Cd, as the concentration of K, Mg and Sr increase, the solubility of Cd increased with it. This is because the difference between the ionic radii of Cd and the other ions (K, Mg, Sr) has a tendency to increase in solubility in the enthalpy of hydration. Also, as the concentration of Ca increased, there was a tendency in which the solubility of Cd decreased. This is because the ionic radii of Cd and Ca are similar to each other and there was a tendency that the solubility decreased in the enthalpy of hydration. Through this experiment, the study shows the tendency of the change in solubility of several solutes by comparing ionic radius and the enthalpy of hydration, and if this result is used, the processing of certain heavy metals in the bodies of water can be even more effectively used than the previous method.
