紫茉莉生物時鐘機制的研究
Mirabilis Jalapa is a wild flower, which is often seen in countryside of Taiwan. This plant blossom regularly every day around PM 3:00-6:00. Since its regular behavior, it has the potential to become a model plant for research on circadian ryhtem. According to the on spot observation, a Mirabilis Jalapa will bloom consistently, whereas a minority of flower will bloom earlier or later. First, we observe how Mirabilis Jalapa response to disparate environmental conditions. Under a short period of light(8h) and an average period of light(12), Mirabilis Jalapa acts as normal. But under a long period of light, it flowers approximately 1h ahead of time. When under a continuous light, Mirabilis Jalapa shows a regular flowering in the first four day, and after that, circadian rythem of flowering terminate. The ripe flower buds mentain unbloom for 10 days or more, finally end up withered. Meanwhile, floral meristems are also suppressed. Temperature alter seems affct the flowering slightly. Second, we use SDS-page to detect protein divergence 6h interval.But as many of the earlier attempt, the floral stimuli is not sensible for average protein qualitative analysis. So we decide to take more direct approch by genetic experiment. From supplemental material of article” Orchestrated Transcription of Key Pathways in Arabidopsis by the Circadian” we obtain a group of genes regulared by bioclock in Arabidopsis.With Bio Informatics we choose 41 single gene, and compare with sequences in other species, designing promotors to isolate similar genes in Mirabilis Jalapa. Use rt-PCR to detect the level of certain gene expression,and compare characters of those genes in Mirabilis Jalapa with those genes in Arabidopsis. We also blast those 453 genes to the database of animal, trying to recognize some genes that is widely separated between disparat species. And test these genes in Mirabilis Jalapa to confirm this result.本實驗先針對紫茉莉開花生物時鐘的特性進行觀察,並以不同的變因測試對紫茉莉開花時鐘的影響,紫茉莉個別花朵開花生物時鐘並不一致,長日照會對植株造成開花時間提早(約1 小時)的影響,全日照則會對花芽分生及開花行為造成抑制,溫度對於開花影響不明顯。而後利用蛋白質電泳對不同時間點的樣本進行分析,由於開花激素存量極微,故並電泳結果無明顯差異。再來以阿拉伯芥已知與生物時鐘有關的基因中經過生物資訊(Bio Informatics)預測在紫茉莉中存在與開花及光週期有關之基因(CAA75629 CAB56039 AAB60305 AAC49807 AAA82068),針對該基因進行表現量的測定,驗證該基因與開花生物時鐘的關聯性。針對動物界與植物界中已知與生物時鐘相關的基因進行交叉比對,希望找出跨界廣泛存在的生物時鐘基因,接著測試紫茉莉中該基因的存在與否及表現狀況與其他物種的差異,驗證該基因分布的廣泛性。
超聲波在液體的探討
本實驗一開始主要探討超聲波在水中的基本性質,如:指向性、衰減性…等。實驗發現,超聲波的衰減會同時與其指向性以及衰減性有關。 接著希望利用超聲波在水中的物理性質,近一步測量超聲波在水中的聲速,實驗中則利用駐波以及聲光效應測量。在駐波法測量聲速的實驗中,用洗淨機當作聲源,內部放置量筒,量筒內盛水後放入木屑,並使聲波在其中產生駐波即聲浮現象,求出波長後反推聲速,測量出的聲速誤差值僅有1.13%,而在使用聲光效應測量聲速的實驗中,使1.65 MHz 的超聲波在自製的壓克力容器內部所裝的水中產生駐波後,以波長650 nm 的紅光雷射通過,在遠處屏幕即產生似於光柵繞射現象,藉著屏幕上的繞射條紋反推該液體聲速,測量出聲速誤差均在5%以下。 在觀察聲光效應實驗中,發現過段時間後有氣泡產生,由文獻上,得知此現象為超聲空蝕現象(Acoustic cavitation),就設計實驗測量聲場中聲壓分部,並利用蠟紙觀察氣泡的成長。實驗發現聲場中的聲壓強度以及液體的表面張力和蒸汽壓會影響到產生空蝕的臨界值及產生氣泡的數量。 ;At the beginning this experiment explores the ultrasonic base in the water, including its velocity, the physics property of liquid, direction, and attenuation etc. . . At first, we use methods of standing wave to measure the velocity of sound under the water, using an ultrasonic cleaner as the sound source and putting some wooden powder in the water. As the standing wave accrues/produces, the powder will “stand still.” To measure the length between two grains of powder, in this way we can calculate sound velocity. Another method we use is diffraction of optics. Put 1.65 MHz source and water in a transparent container; then using laser through it. At the board much diffraction light stripes are created. By this way, we can estimate the velocity. Following these ways can calculate velocity precisely. In these experiments, some bubbles create in the container are discovered. We learn it is so-called “Acoustic Cavitation” based on the reference paper. Besides, we design experiment to know the bubbles’ growth and the number of the bubbles is connected to the physics property of liquid. We use different kinds of liquid with different vapor pressure and surface tension. Finally, we know when it has the smaller surface tension and bigger vapor pressure, the liquid makes bubble velocity grow faster and larger amount of bubbles are produced.
太陽系外行星光度研究
搜尋太陽系外行星(extra-solar planet;exoplanet)是當今天文學家最重要的計畫之ㄧ;其中,當系外行星經過其主恆星碟面時,會造成光度略微下降,稱之為凌日現象(transit) 。本研究便是利用鹿林天文台SLT(Sne Little Telescope)望遠鏡來拍攝兩顆已知的系外行星HD 189733 b 和HD 209458 b在凌日時的影像。 我們得到約4000 張影像,再經過影像修正與資料分析後,我們作出凌日光變曲線圖、Bin圖及相位圖,並從中探討其特性。 經分析判斷後,HD 189733 看到一個剛開始發生和一個完整的凌日現象,分別由B濾鏡和 R 濾鏡所拍攝;而 HD 209458 則看到兩個剛開始發生,三個要結束的凌日現象,分別由B濾鏡、R 濾鏡和 Hα 濾鏡。 並由光變曲線,推得HD 189733 的基本參數,包括:行星半徑為 1.242個木星半徑、軌道傾角為88.94 度以及軌道半徑為 0.03115 天文單位。 Since 1995, more than 200 extra-solar planets have been found. Until today, astronomers still make efforts in searching extra-solar planets because it’s one of the most important projects in this century. During the crossing by the stellar disks (i.e., transits), the exoplanets will cause the brightness to decrease by a small amount. In the project, we have focused on the observations of two known transit exoplanets, HD 189733 b and HD 209458 b. The photometric observations were performed with the 40-cm SLT telescope on the Lulin Observatory. The results from the image procuring, data reduction and analysis are presented. We accrue and plot the light curve, bin and phase. We found out that HD 189733 has two transit ingresses with B, R band, and HD 209458 has two transit ingresses, two transit egresses with B, R, Hα band on phase. We figure out planetary parameters, RP is 1.242 RJ, inclination is 88.94° and orbital semi-major axis is 0.03115 AU by transit light curve.
石油工業廢觸媒於水泥〈砂〉漿中對其流度影響之探討
隨著科技的發達,工業廢棄物應運而生,在地小人稠的台灣,每年就產生約6000 公噸的廢觸媒,為了讓環境免於遭受廢棄物的污染,本實驗著重於廢觸媒的再利用,探討廢觸媒作為混凝土中礦物摻料對水泥(砂)漿流動性的影響。
本實驗所採用的廢觸媒來自石油裂解廠的靜電集塵廢觸媒,主要由SiO2 及Al2O3 所組成且具有部份非結晶相和卜作嵐材料之特性,外觀為乳灰白色粉末、含水量2.8﹪,溶於水中有放熱現象,pH 值為3.85。廢觸媒對水的親和力大,添加至水泥(砂)漿中會使得漿體的流動性減小,因此必須藉由提昇強塑劑劑量才能提高工作度。
在水膠比(W/B)為0.42 時,隨著強塑劑HPC-1000 劑量的增加,水泥漿的流度明顯增加,而且適當量的廢觸媒取代水泥,能維持水泥漿一定的流度。當強塑劑HPC-1000 劑量為3.0﹪、砂/水泥=2.75 時,隨著水灰比(W/C)的增加,水泥漿的流度也明顯增加,而同條件下,不論水膠比(W/B)0.485 或0.55 時,廢觸媒取代水泥之水泥砂漿的流度比飛灰、爐石、高嶺土好,與矽灰相當,其最佳取代水泥量為15﹪。
As technology continues to develop, a considerable amount of industrial wastes have been produced.In Taiwan, over 6,000 tons of spent catalysts were brought out yearly. If such wastes can be reused in some ways, it may be helpful to protect our environment from being polluted. This study was taken to determine the influence of spent catalysts on the flowability of mortar while the catalysts were used as mineral additives for concrete. Since the catalysts could reduce the flowability of cement pastes because of the affinity between the catalysts and water, it was necessary to have superplasticizers added to improve the fluidity of the mortar.
The spent catalysts used in this study were spent electrostatic precipitator cracking catalysts, called Epcat, which were provided by petroleum refining companies. Comprising mainly silicon oxide and aluminum oxide, the off-white catalyst powder present water content of 2.8%, pH value of 3.85 and exothermic reaction with water.
In this study, it was found that while the ratio of water to binder (W/B) was 0.42, the flowability of the cement pastes increased with the increasing addition of superplasticizers. Besides, the flowability of cement pastes kept steady while a proper amount of Epcat was used to replace cement.When the ratio of sand to cement (W/C) was 2.75, with 3.0% superplasticizers HPC-1000 added,the flowability of the mortars markedly increased while the W/C increased, and the replacement with spent catalysts made the mortars show similar flowability as silica fume but better flowability than fly ash, slag and kaolinite, no matter the W/B value of the cement pastes was 0.485 or 0.55. In fact, the best Epcat replacement for cement was 15%.
植物的彩妝
我們的研究報告,是對校園中所種植的各種變葉木所做的一個研究,經過一連串的實驗證明後,我們確信花青素對變葉木的光合作用會有所影響。接著,我們測定出未氧化的植物色素與已氧化的植物色素吸光能力有很大的差異,我們假設花青素可以吸收某些特定波長的光以防止植物色素的氧化程度過強,實驗後證明我們的假設是正確的。另一方面,我們預期花青素具有保溫的機制,故設計了一個在低溫下花青素可保溫的實驗以證明之,結果和我們的假設相符合。我們預期花青素可利用保溫的特性降低植物因低溫所造成的傷害,減少農業上的損失。This study is about the Codiaeum variegatum which is grown on campus. After a series of experiments, it was proved that “anthocyanin” has a significant influence on the photosynthesis processing in Codiaeum variegatum. A great difference in the pigment of plant’s light-absorbing ability between the oxidized plants and the non-oxidized ones was also found in the experiments. Therefore, it was supposed that anthocyanin could absorb some special range of wavelength to avoid the pigment of plant to over-oxidize. The result of this experiment is in accordance with our supposition. In addition, we anticipated that anthocyanin has the ability to stay warm. By a designed experiment we successfully found that the result is exactly the same as our assumption. According to the findings of our study, we expect the characteristic -- ”staying warm” of anthocyanin could be applicable to decrease the harm to plants caused by the low temperature, and thereby to reduce the loss in agriculture.
台灣植物染與光敏有機太陽能電池
由於低廉成本、無毒及其他原因,由二氧化鈦、有機染料及電解液所製造的光敏有機太陽能電池(DSC)被預測即將成為一種大規模廣泛流行的太陽能電池。本實驗比較合成染料(像紅汞和疊氮離子)及成本較低且無毒的天然植物染料用於太陽能電池的效能。有些天然植物染料的效能大於合成染料的效能,像是紫色高麗菜、地瓜……等。在研製太陽能電池的過程中, 本研究利用自製的幾丁質燒結出的奈米顆粒成效極佳,不但粒徑大小符合,在燒結的過程中也不需經過物理研磨及介面活性劑的輔助,並且在低溫下即可燒結,並由BET 和SEM 測得幾丁質燒結的TiO2 的孔隙度大於標準燒結的TiO2 的孔隙度,因此本實驗決定利用去乙醯化之幾丁質扮演太陽能電池的二種角色:介面活性劑及保護劑。在本實驗中,部分的電池效能不盡理想,或許是因為所有的太陽電池樣本均使用相同的電解液(I3-)。要找到每種太陽能電池最適合的電解液則需要更多的研究。Because of the desirable features of low cost, non-toxin, and other reasons a dye-sensitized nanostructured solar cell (DSC) composed of nanocrystalline TiO2, organic dyes and electroiytes is expected to be in prevalent use. This study compared the differences in the functioning of different dyes in the solar cells, specifically those between the synthetic dyes, such as Merchrochronate and Polypyridyl complexes of ruthenium (N3-), and dyes made of natural plants which cost less and are not toxic. Some natural dyes, such as purple cabbage, sweet potato, etc, were found to have better efficiency than the synthetic dyes. The study makes use of self-made chitin to sinter nano particles, and the result is excellent. First, the particle radius meets the size requirements. Second, in the process of sintering nano particles, no physical pulverizing or surfactant assistance was needed. Third, the nano particles can be sintered at a low temperature. Fourth, from BET and SEM measurements, the degree of aperture of TiO2 sintered with chitin is superior to that sintered with Triton X-100. For these reasons, the de-acetylated chitin was chosen to serve as surfactant assistance and protector in the solar cells in this study. The study also found that some solar cells were not efficient enough. Maybe it is because all the samples of solar cells in this study were produced with the same electrolyte (I3-). Further study is needed to figure out the most suitable electrolytes for each solar cell.
新網路模式對抗無尺度流行病傳染A New Network Model to Fight Against Scale-Free Epidemi
流行病的傳染如同一個無尺度網路,但有一些特殊特性在發展一套新傳播模式時,是需要被詳加考慮的。我採用時間位移(t 與ti 分別以t?(ti?1)與ti?(ti?1)來取代)至無尺度網路模式中,再引入一個非連續強力函數H(t; ti?1, L+ti?1)來描述流行病傳播的特定時段與強度,並重新定義機率p 為無效傳染率。之後,我建立了新模式「無尺度流行病模式」-SFE-1與SFE-2。模擬六種病原的傳染途徑,結果證實SFE-1與SFE-2模式是正確與確切可用。案例研究結果,顯示傳染強度H可為固定值或為變數;p可以是一固定值、雙固定值或為新增病例的函數。更進一步解析美國AIDS病例在不同族群與行為上的差異,獲知亞裔/太平洋裔與印第安人/阿拉斯加人的H值低於其他族群,其原因可能是由於小的族群具有較高的接觸所致。異性性接觸的H值低於其他,顯示性交易是傳播HIV的主要途徑。SFE-1與SFE-2模式也可被用在流行病的預測上,因為SFE-2使用已知值而非估算值,所以SFE-2模擬結果較佳;但是SFE-1更可以明確提供一個流行病在失控或控制下的預測結果。無尺度流行病模式可以協助所需警戒的程度與政策決定的計畫結果。因此在幫助政府評估社會經濟成本與健康憂慮上是一個有用的工具。所以我提出一個確切可行的對抗無尺度流行病傳染新方法,並詳細說明運作流程。The course of epidemics resembles a scale-free network, but some specific elements should be considered in developing a new model. I introduced a time shifting (replacing t and ti by t?(ti?1) and ti?(ti?1)) and a discontinuous forcing function H(t; ti?1, L+ti?1) into the scale-free network model to fit the specific period and intensity of the infection, and redefined the probability p as an invalid infection rate. Then I proposed the new Scale-Free Epidemic Models, SFE-1 and SFE-2. The simulation results of six types of epidemic transmission showed that the SFE models were accurate and useful. In the case studies, the results showed that H were constant or variable, and p were a fixed constant, a dual constant, or a function of new addition cases in the epidemic periods. The further studies for comparisons of the difference races/ethnics and the difference transmission category of AIDS cases in USA were analyzed. The H value for Asian/Pacific and Indian/Alaska Native race were lower than others, it may be due to small clusters with constant high contact rates. The H value for heterosexual contact was lower than the others, indicating that whoredom was the main transmission for HIV. Both SFE models can be used to predict epidemics, SFE-2 is better than SFE-1 due to SFE-2 using given indices and not conjectured values, but SFE-1 can more clearly suggest results of epidemics when under control or not. SFE models can help the government to determine the level of caution needed and the projected results of policy decisions. They are useful tools in assisting to balance socio-economic and health concerns. I hereby propose a new method to fight against epidemics with detailed procedures of using the SFE models.
太陽能發電環境評估與追蹤器探討
本研究首先探討台灣各地的日照時數與世界重要都市的比較,發現台灣南部日照時數皆超過2000 小時,適合發展太陽能。接著,?了增加陽光的能量密度而加設弗瑞奈透鏡,雖然能順利的使照度放大三百餘倍,但歲日照角度的影響甚鉅,?了克服角度的問題,我們決定開發自製的追蹤器來改善角度的問題。太陽能板需要改變仰角跟傾角(雙軸調整),由光感應器判斷及自動控制程式,判斷隨時辰與季節變化的太陽角度。當搭配奈米塗料、弗瑞奈透鏡與追蹤器,總輸出功率可增加約50%。太陽電池表面玻璃會阻擋藍紫光的吸收,但本研究在太陽能板上塗佈奈米塗料,發現能增加短波長的吸收;經實驗後奈米等級表面具有自潔效應,可防止灰塵雨滴的堆積影響光線吸收,具有開發價值。This project first compares Taiwanese locations with other places in the world on average daylight times. It was discovered that southern Taiwan has the longest average daylight time all over 2000 hour sand therefore most ripe for solar power development. To increase the energy density of solar Fresnel lenses were incorporated. Although this has the advantage of magnifying illumination by three hundred percent, the alignment angle for the solar panel will have a significant impact on performance. We then designed and built a automated tracking device with illumination sensors to control the elevation and inclination of the solar panel which adjusts the angle according to environmental conditions such as time of day and season. When solar cell collocate Nano coating, Fresnel lens, tracking device, its power can promote almost150%. The glasses on the solar cell will interfere solar cell absorbing blue and purple light, but we lay on a Nano coating and we find Nano coating can improve solar cell to absorb short wave; and surface o Nano have lotus effect, it can prevent dust and rain effecting solar cell absorb lights, and it is worth developing .
Is the fruit safe?-吊白塊的簡易自製試劑
吊白塊是一種在現切水果中常見的食品添加物,它可使剛切的水果不易被氧化,並同時具有漂白的效果,但此種添加物會對人體造成許多疾病。本研究針對吊白塊作嘗試性的初級檢驗,選用一般常見的氧化劑和染料,自行研發簡易的檢驗方法,且進一步製作安定性佳且攜帶方便的試紙。本實驗結果發現,由衛生局提供的「藍吊試劑」本身不甚穩定,且顏色變化不明顯;在自製檢驗試劑方面,效果最佳的是過錳酸鉀,濃度可測至0.0005M,且反應相當快速,唯試液容易與水果表面的Fe(II)離子反應;孔雀綠和晶紅酸等染料效果亦佳,且變色相當明顯,但反應時間較長。Rongalit is a bleaching agent commonly used as a food additive. It can prevent fresh fruits to be oxidized (without color-changed), especially when they were cut for sale. However, as for this additive, it is not good on health and is necessary to be detected. The test-paper currently used, the so-called “blue-test paper”, can be obtained from the Department of Health (Taipei). However, its stability is poor; the color change is not clear when it reacts with Rongalit. For this reason, I developed simple methods for detecting Rongalit by using various oxidizers and dyes. A test-paper, with better stability and easily for carry, was successfully developed. The findings show that the use of KMnO4 on the homemade test-paper provides the best result. The reaction time is short and the limit of detection can be improved to 5 × 10-4 M. The color changes were also clear when malachite green and fuchsin acid were used, but the reaction times were longer.
