Enhancing rotor performance of a small-scale drag-type vertical-axis wind turbine with vertical guide vanes through Taguchi optimization
No full textThis study used FlowVision, a commercial CFD software, to simulate the operation of a small-scale drag-type vertical-axis wind turbine with vertical guide vanes. The simulations were conducted ranging from 4 m/s to 8 m/s, which reflects typical conditions for small-scale wind turbines. The rotor blades and guide vanes were optimized using the Taguchi method to improve the rotor performance. In the Taguchi optimization, the control factors investigated were the blade diameter, number of blades, and number of guide vanes. How these factors affect the rotor’s performance was discussed. The results indicated that the number of guide vanes most significantly influenced the rotor rotation of the investigated control factors. The blades and the guide vanes exhibited significant interactions. The guide vanes functioned as flow augmenters, directing and accelerating incoming airflow into the rotor. They also shield incoming airflow to prevent it from affecting the returning blades. However, using an excessive number of guide vanes may result in low rotor speed. The optimum wind turbine configuration was 8 blades, blades with D/Dr = 0.25 in diameter, and 6 guide vanes. The maximum power coefficient CP,max for the optimum configuration was 55.56% higher than that for the worst configuration.補正完畢US

A high sensitive nanomaterial coated side polished fiber sensor for detection of Cardiac Troponin I antibody
No full textThe advent of evanescent field based fiber optic biosensor and advancements in nanotechnology has create an excellent opportunity in label-free detection of biomarkers which plays vital role in the early, rapid and accurate diagnosis of acute diseases. In this work, we demonstrate a high sensitive Molybdenum Tungsten Disulfide (MoWS2) coated side polished fiber (SPF) biosensor for accurate and early diagnosis of cardio vascular disease (CVD). The Cardiac Troponins I (cTnI) is identified as a biomarker of interest for early and rapid diagnosis of CVD. The proposed SPF biosensor exhibits surface plasmonic resonance (SPR) detection due to the evanescent field interaction between MoWS2 nano coated side polished region and anti-CTnI. The proposed SPF biosensor possess the high sensitivity of 82% to detect the cTnI antibody with a limit of detection (LOD) about 17.5 pg/mL. The peak SPR shift have been calculated as 61 nm for analyte concentrations of 500 pg/mL Moreover, the proposed SPF biosensor possess the high degree of selectivity and environmental stability to CTnI among three analytes such as CTnI, Estrogen and Glucose. The hydrophobic interactions of MoWS2 and cTnI antibody leads to chemical free biofunctionalization of antibody in the sensing region. Hence, the simulation results shows the surface interaction strength calculated as 1.29 KJ mol−1/nm2 in order to evaluate the hydrophobic interactions. Thus, the proposed optical biosensor is a promising candidate for “point-of-care” testing of CVD disorders and preclinical assessments.補正完畢US
董事新興風險與董事及經理人責任保險之轉變
No full text本文探討ESG 概念與董事的ESG 職責，說明ESG 訴訟案件，以及董事及經理人責任保險於定價、承保條件的改變。企業若未適當應對氣候與ESG 以符合監管要求，將面臨訴訟或監管調查風險，ESG 可能產生潛在法律風險及訴訟成本，例如董事會疏於治理違反受託義務與公開資訊揭露法律責任。當前董事新興責任風險來自氣候與ESG 訴訟，且涉及違反受託義務或證券詐欺，保險人開始應對氣候訴訟風險，準備因應Caremark 訴訟與董事會關鍵任務ESG 責任。因保險人與被保險人雙方皆可受益於氣候治理改善，保險人更有動機監督氣候治理，加強氣候治理審查，瞭解被保險人關鍵任務暴險，以及處理關鍵任務暴險的治理結構。補正完畢TW
A Reflection on the Legal System Protecting Intermediate Category of Workers in Italy
No full text隨著零工經濟蓬勃發展，零工經濟勞動者之勞動條件漸漸受各界關注，繼而勞動者若未被歸類為勞工，應如何保障其勞動權益之議題亦受到重視。衡諸上開議題在國際社會間已受到廣泛討論，在我國亦成為眾所矚目之焦點。對此，義大利在1973年即於該國民事訴訟法中創設介於「勞工」與「自營作業者」兩者間之中間類型，並將之稱為「持續協調的合作者」(Continuous and Coordinated Collaborators, Co. Co. Co.)，亦即中間類型勞動者，並持續不斷修正相關法制，近年來更直接明文將部分零工經濟勞動者納入保障，該國近半世紀以來之法制發展與實施經驗應具參考價值，對於我國未來建構中間類型勞動者法制，有一定的啟發性。
有別於我國著重在勞動者職安衛面向之保障，且設有較為完備之法令，義大利中間類型勞動者法制之保障範圍，除上開訴訟程序之保障外，其規範保障內容尚涵蓋中間類型勞動者得在契約存續中合法暫停履約、在特定時間工作之補償制度、禁止就業歧視、隱私保護、請求訂定書面契約及知悉一切有助於保障其個人權益與安全資訊之權利等；至於集體勞動權益之保護方面，該國集體活動之發展甚為活躍，近年來更簽訂多項團體協約，亦值吾人持續關注。補正完畢TW
Detecting copper ions in aqueous solutions through interfacial potential modulation in liquid crystal-based sensors
No full textThis study introduces a novel liquid crystal (LC)-based sensor designed for copper ion detection by enhancing the potential at the LC/aqueous interface. The sensor employs an amphiphilic molecular probe, 2-(4′-pentyl-[1,1′-biphenyl]-4-yl)-4,5-dihydro-1H-imidazole (5CB-imid), doped into 4-cyano-4′-pentylbiphenyl (5CB) to create copper-selective LCs. At the LC/aqueous interface, the specific interaction between copper ions and 5CB-imid increases the interfacial potential, promoting a homeotropic orientation of the LCs and resulting in a distinct bright-to-dark transition in the optical signal. Zeta potential measurements confirm the increase in surface potential upon copper ion binding, and X-ray photoelectron spectroscopy verifies the presence of copper ions at the interface, supporting the proposed detection mechanism. The sensor achieves a lowest detectable concentration of 5 μM, well below the U.S. EPA’s permissible limit of 20 μM for drinking water and exhibits high selectivity, as it does not interact with other common divalent ions. Unlike other optical sensors, this LC-based system operates without the need for sample pre-mixing, making it highly practical for on-site applications. Its effectiveness was further validated through successful detection of copper ions in wastewater samples from an electroplating factory, showing reliable performance comparable to atomic absorption spectroscopy. Overall, this LC-based sensor offers a sensitive, selective, and efficient approach for environmental monitoring of copper ion contamination in industrial wastewater.補正完畢NL
