「曲」之有道,「蛤」才知道

本研究以蛤蜊殼粉摻配水泥塊所構形的河道坡堤及形狀為主題,透過自行設計的落錘重力、摩擦力實驗,探討不同比例蛤蜊殼粉摻配的水泥,對水泥塊特性的影響;模擬不同坡道形狀與結構,比較對水流與生物 棲息的影響,結果發現20%蛤蜊殼粉摻配的六邊形蜂巢水泥塊能承重達218kg/ 片,耐衝擊性佳。摻配比例越高,吸水率增加、釋水量較少。蛤蜊殼粉μs≈0.81>顆粒μs≈0.58,蛤蜊殼粉的平均粒徑及偏差值為0.028+_0.016毫米,有利於水中生物攀附。梯形、長方形、平行四邊形的凹凸交錯坡道能有效減緩水流速度和堆積作用且黑殼蝦亦偏好此結構的棲息環境。本研究為了改善傳統水泥溝渠生態不友善的缺點,展現 蛤蜊殼粉水泥塊在生態共融、資源再利用與綠建築應用上的潛力。

啞鈴幫我數與運動姿態分析系統

健身房四處林立,健身為現代人所崇尚的活動,人們知道健身的益處,但須持之以恆才能享受,否則容易受到傷害。根據研究證實適當運動對身體的益處大於壞處。傳統啞鈴只是一種健身器材,但也是最佳器具之一,然而每次操作時使用者須自行計算次數,使遺漏次數、多算次數等問題層出不窮,容易造成使用者心理負擔和增加運動傷害的可能性。在作品中我們將啞鈴結合科技,使用時在啞鈴或手機設定次數,啞鈴即可幫助使用者計算次數,也能糾正使用者動作是否標準,當達到設定次數時,啞鈴會發出聲音提醒使用者。系統以ESP32為主控器,搭配6軸加速度感測器偵測慣性運動,介面設計有HMI、心率感測器及藍芽無線傳輸控制,再經由手機APP程式記錄操作者每次運動姿態。

Non-invasive study of the electrical activity of the brain of various chordate animals

In clinical practice, EEG is used to diagnose a number of neurological diseases and to diagnose epilepsy. But at present, the question of the nature of EEG has not been completely resolved and is of great scientific interest. There have been no studies at all on the non-invasive study of the electrical activity of the brain of the shark superorder, which belongs to the class of cartilaginous fish. By studying the electrical activity of the brain of various gnathostomes, it is possible to obtain an answer to the question of the emergence of rhythms from the point of view of phylogenesis and evolution, and by comparing their EEG with the human EEG, one can identify similar patterns that help in the study of reactions to various influences. During the work, for the first time, EEG indicators of spotted cat sharks, ECG, heart rate and respiratory rate of cat sharks and toads were obtained. In the future, it is planned to assemble a smaller neuroheadset for non-invasive studies of the electrical activity of the brain of small animals (sharks, toads, monitor lizards). This data can be used for evolutionary and medical research. *No animals were harmed during or after the experiments.

陸遙知馬力——山蛩傳

福爾摩沙山蛩(Spirobolus formosae),分布於台灣北部低中海拔地區,為台灣特有種,棲息在潮濕腐質土或是爛掉的木頭中。馬陸在成長過程中,體長會增加,但體節數不變。大部分的福爾摩沙山蛩體節數在56-62節之間。每節有四隻(兩對)步足,尾部一節沒有步足的,雄馬陸除此節外,第七節也因生殖器而沒有步足,雌蟲步足公式:(體節數-1)×4;雄蟲步足公式為:(體節數-2)×4。高強度震動15分鐘後,馬陸鑽土的深度從平均值5公分變成7.375公分。馬陸為間歇性行走,雌雄無差。不同介質對於馬陸的行走並無太大影響。介質傾斜角度對於馬陸有非常大的影響,到0度以後速率明顯下降,D的速率在90度時甚至接近0。

風水輪流轉-探討颱風和季風共伴效應對台灣降雨的影響

本研究探討颱風與東北季風共伴效應對台灣降雨及災害的影響。透過歷年颱風案例發現,共伴效應可能會導致多地嚴重淹水、道路斷裂、人員傷亡等災害。本研究自製雨量模擬實驗平台。模擬結果顯示:颱風從不同方向接近,降雨分布不同:當颱風從東北方接近台灣時,東部、北部雨量較多;颱風從台灣東方接近時,東部的雨量較多;颱風從台灣的東南方接近時,南部的雨量較多。單獨模擬東北季風時,台灣北部雨量最多,其次是東部,把東北季風的降雨量和颱風的降雨量相比,東北季風帶來的雨量較多。在共伴效應模擬時,實驗結果有兩種可能:颱風和東北季風產生共伴效應,使東部和北部的降雨量增加;東北季風風速增加,可能會破壞颱風結構,使雨量減少。

有正就贏

本研究的目的是探討巧克力遊戲,切到剩1塊巧克力,對方無法再切時,就贏得遊戲,巧克力紙板的形狀及尺寸與遊戲獲勝的關係。 研究結果發現:巧克力紙板是正方形,後行者切出正方形給先行者,就會贏得遊戲。若正方形的邊長為A,先行者切給後行者n條,先行者贏的比率的分母為(A-1)+(n-1)2,分子為(A-2)+(n-1)2。 巧克力紙板是寬為A,長為B的長方形,先行者切出正方形給後行者,就會贏得遊戲。若A≦2,後行者贏的比率的分母= A+B-2;若A>2,後行者贏的比率的分母=A×(A-2)+B。 此遊戲獲勝的關鍵是「正方形」,先行者或後行者只要能切出正方形尺寸給對方,就會贏得遊戲。

羽轉綠肥-自製肥料對蔬果生長的影響

羽毛廢棄物是畜產類廢棄物排名第二大宗,為了提高廢棄羽毛的實用價值與效益,我們利用啤酒酵母菌進行雞羽毛分解。經啤酒酵母分解一個月後的雞毛液肥,含有胺基酸濃度約為0.17 M,是市售肥組的5.67倍。以雞毛液肥灌溉高經濟價值的彩椒及福山萵苣,彩椒果實總質量比市售肥組高出84.6%,果實中含有葡萄糖濃度為23.8%,比市售肥組多出49.7%。碘量法的抗氧化能力試驗中,發現雞毛液肥灌溉的彩椒抗氧化能力比市售肥組高出91.3 %。清除DPPH自由基的能力實驗中,雞毛液肥組的彩椒果實汁液清除自由基能力約是市售肥組的2.82倍。雞毛液肥灌溉的福山萵苣的葉片總質量比市售肥組多出116.2%。可以發現啤酒酵母分解的雞毛液肥,確實可取代市售肥料,當作彩椒及福山萵苣的養分。希望藉此研究能將廢棄雞毛再利用,減少環境負擔,讓農業永續發展。

Bifunctional Nanostructured TiO2 photoelectrocatalyst for Improving Overall Water splitting performance

Titanium dioxide TiO2 is a semiconductor, that has great chemical and physical properties, such as remarkable resistance against corrosion, chemical stability, and it’s a non-toxic material. Due to these properties, it rises as an excellent candidate for a wide range of different applications, such as being a popular material for solar cells, paints, cosmetics, energy storge devices, and water splitting. For photoelectrochemical water splitting to generate Hydrogen, a large surface area is essential, to be maximized to enhance photocatalytic redox processes and hence improve overall efficiency. Therefore, different methods have been utilized to fabricate TiO2 nanotubular structure. However, they either encounter a difficult process because of a long synthesis time or the need of expensive precursors. In our work, we demonstrated a study of enhancing 1 D TiO2 film to perform as a bifunctional catalyst (works as cathode and anode). As it is known that TiO2 is kinetically hampered as cathode for producing hydrogen from water, this is due to sluggish electron transfer at the interface between TiO2 and water and the conduction band of the TiO2, which is more negative than H+/H2. To tackle this problem, TiO2 film should be modified. In this work, we modified the TiO2 as bifunctional by investigating different parameters in detail, like the anodic oxidation solution content, anodic oxidation time, and the role of the polyethylene glycol chain. Electrochemical characterization and SEM, and XPS were utilized to prevent the nanotubes structure and to confirm the chemical bonding as well as investigating the physical properties such as resistance and electron kinetic mobility.

In Silico Carotenoid Compound with Protein in Durian (Durio zibethinus Murr.) Seed Waste and Hedonic Test Innovation in Making Healthy Cereal Organic (HCO) (Nutrient-rich Functional Food Alternative)

Durians’ seeds have potential as a food source due to their content and nutrients. Durians’ seeds contain fiber, minerals, vitamins A, B1, B2, C, carbohydrates, folate, potassium and copper. Nutrients are needed for the body's health and growth and development process. Durians’ seeds have the potential as a nutrient-rich food alternative. Researchers made an innovation in the form of cereal, Healthy Cereal Organic (HCO). Analysis of durians’ seed content through two stages. First, wet lab examination and second, in silico method. The wet lab examination shows the results that durians’ seeds contain 10.17 Kcal of fat energy, 4.09% ash content, 11.25% water content, 72.79% carbohydrates, 1.13% total fat and 10.74% protein and the in silico method shows the content of carotenoid compounds (vitamin A, quercetin, beta-carotene, zeaxanthin) as a drug delivery system which means that this compound is able to be absorbed by the body with the help of albumin as a carrier that maintains stability and increases its activity. Feasibility analysis based on toxicity tests, Durians’ seed compounds show inactive (non-toxic) results. Allergenicity test showed non-allergen durians’ seed content. Hedonic test was conducted on 20 panelists dominant to the HCO1 sample for aroma by 60%, texture 90%, taste 40%. It can be concluded that durians’seeds can be used as a basic ingredient for making nutrient-rich Healthy Cereal Organic (HCO).

「泡生溶溶」---泡泡除塑淨水法的研究

本研究透過不同介面活性劑來吸附海洋微塑粒,初步發現,無患子的親油性最好,TDS值可作為微塑粒濃度的檢量線。為了解介面活性劑的親水性值(HLB值)對起泡力及清除率的影響,加入HLB值為4的白蠟油(油性介面活性劑)進行實驗,發現海塑粒無患子起泡效果最好。泡泡水去除海洋微塑粒效果約為8.3%,無患子溶液約為9.7%,白蠟油約為60.7%,故白蠟油的清除效果最佳,但並不天然。後來,我們發現了天然的親油性介面活性劑―大豆卵磷脂,無患子與其的起泡比例以7:3為最佳,且單純大豆卵磷脂的清除率高達84.14%為目前最高。最後,我們發現此起泡裝置能清除真實海水中37.55%的微塑粒。
