Investigation Of Alzheimer’S Amyloid-Β Protein Aggregation With A New Fluorescent Dye., Emma Alberty
Investigation Of Alzheimer’S Amyloid-Β Protein Aggregation With A New Fluorescent Dye., Emma Alberty
Undergraduate Research Symposium
Alzheimer’s Disease (AD) is the most common form of dementia characterized by the impairment of at least two brain functions such as memory loss and judgement. AD is a progressive illness that can last as many as 20 years. AD is largely considered to be caused by the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. A better understanding of the structure and function of these plaques may lead to clearer understanding of the disease. To analyze amyloid plaques, aggregation assays are often used. During these assays we begin with monomer and place the sample in biological conditions to …

Role Of Extracytoplasmic Function (Ecf) Sigma Factors In The Survival And Symbiosis Of Nitrogen-Fixing Bradyrhizobium Under Desiccation Stress And Comparative Analysis Of Desiccation-Tolerant Rhizobial Isolates, Mohammad Kamruzzaman
Biology Dissertations - Archive
Rhizobia are soil bacteria that facilitate biological nitrogen fixation (BNF) through a symbiotic relationship with legumes such as soybeans. As an eco-friendly alternative to chemical nitrogen fertilizers, rhizobial inoculants can enhance plant growth and yield. However, they face various stresses, including drought (i.e., desiccation). Rhizobia can manage desiccation stress by accumulating trehalose, a disaccharide produced by genes such as otsA, otsB, and treS. Extracytoplasmic function (ECF) sigma factors sense external signals and regulate these desiccation-related genes during the stress. Previous studies have highlighted the importance of EcfG in response to desiccation stress and symbiosis. Based on the protein sequence …

การผสมของเหลวในถังกวนอุตสาหกรรมเป็นกระบวนการสำคัญของหลายอุตสาหกรรมโดยเฉพาะอุตสาหกรรมเคมี อาหาร และกระบวนการทางชีวภาพ ที่มีความต้องการความเป็นเนื้อเดียวกันของสารผสมอย่างมีประสิทธิภาพ ซึ่งมีความท้าทายในเรื่องของเวลาการผสมที่นาน ถึงแม้จะเพิ่มความปั่นป่วน (turbulent) ก็อาจทำให้เกิดบริเวณโซนตาย (dead zone) หรือบริเวณที่สารไม่เกิดการเป็นเนื้อเดียวกัน เนื่องจากกระแสวน สาเหตุมาจากการขาดการออกแบบที่ไม่เหมาะสม งานวิจัยนี้ศึกษาการประเมินวิธีการออกแบบถังผสมโดยอาศัย การจำลองพลศาสตร์ของไหลเชิงคำนวณ (Computational Fluid Dynamics: CFD) ควบคู่กับการประยุกต์ใช้ปัญญาประดิษฐ์ (Artificial Intelligence: AI) ด้วยการผสมแบบไม่ต่อเนื่อง (batch) ของของเหลวกับของเหลวโดยได้ใช้แบบจำลอง Large Eddy Simulation (LES) ในการจำลองพฤติกรรมการไหลภายในถังผสมที่ติดตั้ง ใบกวนใช้ใบกวน VISCOPROP ที่ใช้ในเชิงพาณิชย์ และตรวจสอบผลกระทบของพารามิเตอร์ได้แก่ ความเร็วรอบของใบกวน จำนวนแผ่นกั้น จำนวนใบและชั้นของใบกวน ระยะห่างระหว่างใบกวนกับก้นถัง เส้นผ่านศูนย์กลางถังและใบกวน ระดับของเหลว และคุณสมบัติของของเหลว ต่อเวลาในการผสมให้ได้ความเป็นเนื้อเดียวกันที่ระดับ 95% การวิเคราะห์ความแปรปรวน (ANOVA) พบว่า ความเร็วรอบของใบกวนเป็นปัจจัยสำคัญที่ส่งผลกระทบอย่างมีนัยสำคัญ (p = 0.0026) ปัจจัยรองลงมาคือจำนวนชั้นของใบกวน (p = 0.0223) ในขณะที่ปัจจัยอื่นมีที่ไม่แตกต่างอย่างมีนัยสำคัญทางสถิติ (p > 0.05) ในขั้นต่อมา ผลการจำลอง CFD ถูกนำไปใช้เป็นข้อมูลฝึกสำหรับแบบจำลองโครงข่ายประสาทเทียม (Artificial Neural Network: ANN) เพื่อทำนายเวลาในการผสม โดยเปรียบเทียบประสิทธิภาพของอัลกอริทึม Levenberg-Marquardt และ Scaled Conjugate Gradient ผลลัพธ์แสดงให้เห็นว่า ANN สามารถทำนายค่าการผสมได้อย่างแม่นยำ และมีศักยภาพในการใช้เป็นเครื่องมือช่วยออกแบบถังผสมได้อย่างมีประสิทธิภาพ งานวิจัยนี้แสดงให้เห็นถึงความเป็นไปได้ในการใช้ CFD ร่วมกับ AI เพื่อออกแบบและพัฒนาถังผสมในระดับอุตสาหกรรมอย่างแม่นยำและประหยัดทรัพยากรการทดลองในระยะยาว
