Effect of Co-addition of Sn, Traces of RE and Ca on the Mechanical and Micro Structural Properties of As-cast AZ80 Alloy
Authors: MANCHALA Madhusudhanprasad , VEGESNA Ramachandra Raju
Published: June 2024

In this study, the effect of co-addition of tin (0, 6 and 9 wt.%), cerium (0, 0.3 and 0.6 wt.%), gadolinium (0, 0.6 and 0.9 wt.%) and calcium (0, 0.6 and 0.9 wt.%) on the mechanical and microstructural properties of AZ80 magnesium alloy is investigated. The results indicate that the mechanical properties are improved for all the as-cast alloys when compared to base alloy except for one alloy which is due to the presence of Mg-Sn-Ca phase in high volume fraction. Also, it is found that the existence of Al2Ca, Mg2Ca, Al2RE, MgSnRE and Mg2Sn phases have a significant impact on the mechanical and microstructural characteristics of the as-cast AZ80 alloys. It is observed that without the addition of Sn content, the best room temperature tensile properties are obtained for the alloy containing 1.5 wt.% of RE and 0.9 wt.% of Ca. With the addition of Sn, it is found that the best room temperature tensile properties are obtained for the alloy containing 6 wt.% of Sn, 0.9 wt.% of RE and 0.5 wt.% of Ca.

Visuelle Wahrnehmung bei Platon und Aristoteles
Authors: Hobuß Steffi
Published: June 2024

Plato's and Aristotle's theories of vision have often been read within the dichotomy of passive receiving vs. active constructing. In giving detailed readings of the relevant passages, the study shows how not only this dichotomy is untenable, but also unfolds a critique of representationalist theories of perception. While Plato is interested in visual perception mainly in the context of his epistemology, Aristotle is concerned with a typology of different perceptions and giving a theory of perception in his thinking of the middle. The study draws on the author's work in the philosophy of language and text theory for the favoured interpretation.

Published: June 2024

A solar-based hydrogen production system is analyzed and studied with the intention of optimizing the parameters involved in oil refining industry and the environment of the United Arab Emirates. Methane decomposition in molten salt media using a concentrated solar power system was adopted, since the temperature range required in the system design is achievable with this method. The System Advisor Model software was used in this study with three cases to optimize the system using the levelized cost of heat concept. In Case 1, a levelized cost of heat of 9.32 ¢/kWh was achieved using an optimized system with a CSP-RTUVR-2014 receiver and a Luz LS-3 collector. The design of Cases 1 and 2 exhibited pressure drops along the system of just 10 bar, significantly lower than the 50 bar of Case 3. Similarly, designs of Cases 1 and 2 resulted in maximum receiver thermal losses of around 7 MW, whereas Case 3 yielded 14 MW loss. Analysis of the best-suited molten salt option showed that HITEC solar salt was better than HITEC XL and standard HITEC. A regression analysis was carried out to examine the pressure drop responses since it is a key variable affecting the integrity of the solar system. It was observed that the receiver mass flow rate is the main contributing cause of pressure drop. Through careful operator control of receiver mass flow rate, premature failures of the solar system caused by the pressure drop can be avoided.

Effects of titanium content in ziegler-natta catalyst on the reducibility of triethylaluminum cocatalyst
Authors:   , Sitthijun Pichayapong
Published: June 2024

The Ziegler-Natta catalytic system for olefin polymerization comprises the TiCl4 precursor adsorbed on MgCl2 support and reacted with an alkylating agent to generate active sites. The reduction of TiCl4 valence plays a crucial role in the formation of Ti3+ and Ti2+ active species for ethylene polymerization whereas only Ti3+ active for propylene polymerization. Thus, the reducibility of Ti-based catalyst using AlEt3 cocatalyst was studied during ethylene and propylene polymerization which has not been previously studied yet. For this study, the effect of Ti content on the reducibility was considered through the changing of catalytic activity with the increase of AlEt3 concentration. The results indicated that Adduct High catalyst with high Ti content shows the large-size clustered Ti species and the blockage of the active site on the surface leading to Ti species is hard reduced by low AlEt3 due to the steric hindrance of the formed complex, and then the complete reduction of the buried Ti occurs at the excessive AlEt3 causing the reduction is evidently decreased.  Moreover, the weak binding interaction of Ti-Cl stretching in TiCl4 strongly adsorbed on (110) MgCl2 by Grignard and Ethoxide methods affects the easier exchanging of Cl atom and ethyl group results in more sensitive to the reduction of Ti species by AlEt3 cocatalyst. Therefore, the reducibility depends on the Ti cluster and the interaction of TiCl4 on the surface of catalyst.

Authors:   , Pen Bonita
Published: June 2024

This work aimed to​ treat  contaminated groundwater with arsenic and ferrous iron pollutants to be drinking water standard following by WHO by co-precipitation process and membrane separation process. The relative effect of different solid media types (scouring sponge, scouring pad, plastic ring, and activated carbon foam) and operating conditions on oxygen mass transfer coefficient (KLa) and hydrodynamic bubble parameters was studied. The optimization process of ferrous oxidation and arsenic removal was observed by Design of Experiment (DOE) with Central Composition Design of Response Surface Methodology (CCD-RSM). Lastly, separation process was experimented with conventional process and membrane technology, i.e., settling process, different effect of scouring sponge loading on turbidity removal, and impact of settling process on ultra-filtration membrane fouling. The result showed that scouring sponge was the most effective solid media to enhance volumetric oxygen transfer coefficient around 9-80% by impact of bubble rising velocity not breaking up bubble mechanism. The maximum removal of ferrous by optimization process was Qg =14 LPM, initial pH=8, initial [Fe2+]=5mg/L, adding [Fe3+]=25mg/L and operating time 25 min. However, for arsenic removal with co-precipitation process, the optimization process found under condition Qg=8, initial pH=8, initial [Fe2+]=36mg/L, adding [Fe3+]=25mg/L and operating time 33 min. Furthermore, initial pH and ferrous initial concentration was defined as the most significant factor. In separation process, the removal of turbidity by settling process was remaining around 60NTU while the highest scouring sponge loading (10%) was able to remove turbidity around 15% (not pass WHO standard). Finally, ultra-filtration was used to get complete clear and clean drinking water. The result showed that the performance of settling process before membrane filtration could reduce the membrane fouling mechanism. Thus, the combination of settling process and membrane technology could provide more benefits.

Authors:   , Trang Tan
Published: June 2024

The process of digital transformation (DX) involves the systematic integration of digital technologies, processes, and skills at all levels and functions within an organization, industry, or ecosystem. The emergence and rapid spread of the coronavirus are accelerating DX in all industies and the construction industry is not an exception. Construction companies are on the verge of significant transformation driven by advancements and the adoption of digital technologies. However, knowledge and information about how to implement DX efficiently in construction firms are fragmented and limited. This leads to the failure of DX journey of the majority of construction firms. This research develops a DX implementation roadmap and investigates the Critical Success Factors (CSFs) for DX adoption in the contractors’ perspective. Fuzzy cognitive map (FCM) technique and ranking analysis are applied to analyze the relationship between these factors and rank their importance. Among the 30 CSFs identified through ranking analysis, we found that effective leadership, data security, and the ability to turn data into assets be the most crucial factors for the successful implementation of DX in construction contractors. The results from FCM analysis highlighted that the three most influential factors were effective leadership, the perceived benefits of DX, and the development of a digital strategy and transformation areas. Meanwhile, the three factors that were most influenced by other variables were the research and development capabilities of the organization, the organizational flexibility and adaptability to the market, and the ability to turn data into valuable assets. These research findings contribute to advancing the digital transformation efforts in the construction industry and promoting enhanced business outcomes for contractors in the rapidly evolving digital landscape.

Depression classification on privacy protected facial features data
Authors:   , Mahayossanunt Yanisa
Published: June 2024

This thesis presents depression classification on privacy protected facial features data. Fast depression classification to help patients receive proper treatment is a method that can prevent the damage of depression. However, fast and effective depression classification is difficult because medical personnel are adequate and the time to analyze depression is long per patient. Applied artificial intelligence in the medical field can help reduce the workload of medical personnel. It is also difficult because of privacy protection. Therefore, we utilize extracted facial features from facial expressions in clinical interview videos to develop a machine learning model. The model utilizes LSTM, attention mechanism, intermediate fusion, and label smoothing approaches to improve performance. The experiments were conducted on 474 video patients collected at Chulalongkorn University. The data set was divided into 134 depressions and 340 non-depressions. Our model achieves 91.67% accuracy, 91.40% precision, 87.03% recall, and 88.89% F1-score. In addition, our model is analyzed using an integrated gradient to explain the important facial features. The significant facial features related to depressive symptoms are head turning, no specific gaze, slow eye movement, no smiles, frowning, grumbling, and scowling, which express a lack of concentration, social disinterest, and negative feelings.

Effects of coastal structures on the shoreline change in Phan Thiet bay, Vietnam
Authors:   , Pham Hoai
Published: June 2024

This thesis examined the effects of coastal structures on shoreline change in Phan Thiet Bay, Vietnam from 1988 to 2021. This thesis explored two key objectives; that were the investigation of historical shoreline changes and the effects of structures on shoreline based on the comparison of simulated shorelines with and without structures by using GENESIS model. Moreover, the SWAN model was used for simulating wave data which is an important input for the GENESIS model.

From the shoreline evolution results, it was found that the land loss rate ranged from 0.9 to 8.7 ha/year in 1988 to 2016, while this loss rate increased up to 11.2 ha/year or 83% of the eroded coastline in 2016 to 2021. Moreover, the results found that the shoreline change rate was strongly correlated with the presence of structures and the frequency of typhoons.

The GENESIS model effectively simulated the shoreline in the Western area and the Eastern area in Phan Thiet Bay, with an average Mean Absolute Error (MAE) of shoreline change rate as 2.34 m/year and 5.32 m/year, respectively. The results from GENESIS model reaffirmed the predominant longshore sediment transport direction in this study area was East to West. For the effects of structures to the shoreline change, it found that the beach reclamation project affected the erosion areas up to 1600 m away from its location, while groins and seawalls influenced adjacent shorelines up to 2500 m and 1700 m, respectively. In conclusion, this study contributed results on the historical shoreline change and effects of some specific structures on shoreline change in Phan Thiet Bay, providing fundamental data for applying the coastal structures in future coastal erosion resilience project in this area.
Effect of type and concentration of acid on characteristics of functionalized biochar and its performance in converting fructose to 5-HMF
Authors:   , Bunwichian Pimlapas
Published: June 2024

Biomass, with its high cellulosic content, represented renewable source capable of being converted into essential platform chemicals like 5-hydroxymethylfurfural, levulinic acid, formic acid, and furfural. Currently, conversion of fructose to 5-HMF was achievable through various acid homogeneous catalysts. Although these catalysts yield higher outputs, they might pose challenges in recycling and corrosion issues. This thesis's novel approach involved preparing heterogeneous catalysts through pyrolysis and hydrothermal treatment of watermelon rind to create watermelon rind biochar (WB). Subsequently, WB underwent functionalization using HCl, H2SO4, and H3PO4 at concentrations of 1.6, 3.2, and 4.8N, respectively, at temperatures of 150 °C. These treated WB samples, identified as xWBy (where x denoted acid used and y indicated concentration), served as acidic heterogeneous catalysts. To observe catalytic performance, 0.2 g of biochar catalyst and fructose 40 w/v% were mixed with 30 mL of DI water in autoclave reactor, maintaining temperature of 160 °C for 90 mins. Characterization of pristine and functionalized biochar samples was conducted using Field emission scanning electron microscopic (FESEM), N2 adsorption/desorption, elemental analysis, Fourier transform infrared spectroscopy (FTIR), and Ammonia-temperature programmed desorption (NH3 – TPD). Findings revealed that pristine biochar treated with 4.8N sulfuric acid displayed a combination of microstructural and mesoporous properties, processing specific surface area of 464 m2/g and pore volume of 0.33 cm3/g. Additionally, successful incorporation of acidic functional groups, particularly sulfonic groups, was observed, enabling them to act as acids and facilitate proton transfer to fructose molecules, producing 5-HMF. Quantity of acidity, confirmed via NH3-TPD analysis, measured at 4.31 mmol/g. These catalysts provided fructose conversion of 72.3% along with the highest 5-HMF yield and selectivity of 46% and 63%, respectively. Functionalized biochar showed significant potential in utilizing a cost-effective and efficient catalyst derived from agricultural sources for 5-HMF production.
Perioperative Nutritional Considerations In Patients With Inflammatory Bowel Disease
Authors: Bielawska Barbara
Published: June 2024

Despite significant advances in medical therapy for inflammatory bowel disease (IBD) in recent decades, surgical management remains common in the setting of both Crohn’s disease (CD) and ulcerative colitis (UC). While the risk of colectomy for UC has declined in the biologic era, most patients with CD will undergo at least one intestinal resection in their lifetime. Preoperative nutritional status is a wellestablished determinant of surgical morbidity. Surgery elicits a metabolic stress response that is proportional to the extent of surgical injury. Adequate lean body and micronutrient stores are needed for healing of surgical incisions, and the individual must be metabolically capable of anabolism for tissue repair. Deficits at any point in this process may lead to complications including anastomotic failure, surgical site infections, delayed return of gastrointestinal (GI) function, and postoperative physical disability with prolonged length of hospital stay.

Materi penelitian adalah semen yang berkualitas baik (motilitas spermatozoa ?70%, abnormalitas spermatozoa <20%) yang ditampung dari dua ekor babi jantan landrace, yang berumur ± dua tahun. Rancangan yang digunakan adalah rancangan acak lengkap yang terdiri dari enam perlakuan, yakni: P0: NaClF, P1: NaClF+5% KT, P2: NaClF+10% KT, P3: NaClF+15% KT, P4: NaClF+20% KT, P5: NaClF25% KT. Setiap perlakuan mendapat ulangan lima kali. Variabel yang diukur dalam penelitian ini adalah motilitas, viabilitas, abnormalitas, dan daya tahan hidup spermatozoa. Hasil penelitian ini menunjukkan bahwa hingga jam ke-24 preservasi, penambahan KT 5-25% ke dalam pengencer NaClF menghasilkan motilitas dan daya tahan hidup spermatozoa yang lebih tinggi daripada kontrol (P<0,05), namun untuk variabel viabilitas dan abnormalitas spermatozoa menunjukkan pengaruh yang tidak signifikan (P>0,05). Disimpulkan bahwa level optimal KT dalam pengencer NaClF untuk preservasi spermatozoa babi landrace adalah 20%

El ensayo titulado: Los recursos audiovisuales en el proceso de nivelación en las Ciencias Naturales para estudiantes de 10° grado de Educación General Básica de la Unidad Educativa “Maura Barreto Falcones”, partió de las carencias halladas en la sapiencia previa de la materia antes mencionada. Por lo tanto, el objetivo propone una serie de recursos audiovisuales que fortalezcan los conocimientos en el proceso de enseñanza-aprendizaje en la materia anteriormente referida. Los métodos empleados de nivel teórico fueron: Análisis-síntesis, histórico-lógico, inductivo-deductivo, con un enfoque al sistema del nivel empírico como la encuesta, que sirvió para el diagnóstico del problema detectado inicialmente. Se procesó esta información a partir del análisis porcentual como método matemático y con estas indagaciones se pudo desarrollar estrategias metodológicas que sirvieron para la obtención de información relevante en esta fase. Como resultado, se avala las dificultades en los estudiantes y se propuso una estrategia con un sistema que parte de un objetivo y que consta de cuatro fases (diagnostico, planificación, implementación, evaluación) con actividades establecidas sistemáticamente para la comprensión de la información facilitada y que esta sea significativa en los estudiantes. Finalmente se concluye, que esta propuesta es aplicable y ejecutable para el grupo de estudiantes previamente diagnosticados.

El control constitucional en el Ecuador. Casos de injusticias en la práctica jurídica
Authors: Lojano Lojano Juan Pablo
Published: June 2024

Este análisis destaca la importancia de la jurisprudencia de la Corte Constitucional como un mecanismo para garantizar la efectividad de los derechos fundamentales, especialmente en el ámbito laboral. Algunos puntos clave que se abordan incluyen el derecho al trabajo como un derecho fundamental. La Constitución establece el trabajo como un derecho y deber social fundamental, lo que implica que el Estado tiene la obligación de garantizar a los trabajadores el pleno respeto a su dignidad, una vida digna, igualdad, libertad e integridad personal. El alcance del principio de autonomía de la voluntad individual, que se analiza cómo este principio se relaciona con la eficacia de los derechos fundamentales en la vigencia y disponibilidad de los derechos constitucionales en el contexto de las relaciones laborales.
La acción extraordinaria de protección, se destaca la importancia de esta acción como una garantía para hacer efectivos los derechos, especialmente cuando los jueces ordinarios no aplican las disposiciones constitucionales. Este mecanismo es crucial para defender los derechos individuales frente a la agresión de otros individuos o del poder estatal. Y el enfoque garantista de los derechos, en donde se subraya la importancia de adoptar un enfoque garantista de los derechos en las sentencias judiciales, asegurando que los derechos no sean meramente discursivos y que los principios constitucionales guíen la actuación judicial de manera consistente.

Mục tiêu: Đánh giá độ ngưng tập tiểu cầu (NTTC) và tỷ lệ kháng thuốc chống NTTC ở người bệnh mạch vành (BMV) được điều trị bằng aspirin và/ hoặc clopidogrel.
Đối tượng và phương pháp nghiên cứu: Tiến cứu, mô tả cắt ngang, tiến hành trên 201 người BMV đang được điều trị bằng aspirin và/ hoặc clopidogrel, với thời gian dùng thuốc ổn định ≥ 7 ngày. Độ NTTC được đánh giá phương pháp đo độ truyền quang (Light Transmission Aggregometry - LTA), Tiêu chuẩn đề kháng aspirin và clopidogrel dựa theo đồng thuận về “Phản ứng tiểu cầu cao trong điều trị” (high on-treatment platelet reactivity - HTPR) của Trường môn Tim mạch Hoa Kỳ (ACC) năm 2010.
Kết quả: 150 nam và 51 nữ, độ tuổi trung bình là 62,83 ± 11,02, giá trị trung vị và khoảng tứ phân vị (Median/interquartile range - Med/IQR) của độ NTTC khi sử dụng aspirin là 7,0 (14,5) và clopidogrel là 51,45 (20,9). Tỷ lệ đề kháng aspirin là 19,05%, đề kháng clopidogrel là 61,11%, và kháng cả hai thuốc là 13,44%. Không tìm thấy mối liên quan có ý nghĩa giữa độ NTTC với tuổi, giới tính và chỉ số khối cơ thể (BMI) (p > 0,05).
Kết luận: Tỷ lệ đề kháng thuốc clopidogrel trong điều trị bệnh nhân BMV khá cao (lên đến 61,11%). Liệu pháp phối hợp kháng kết tập tiểu cầu kép (asprin và clopidogrel) làm tăng hiệu quả điều trị và giảm tỷ lệ đề kháng thuốc chống ngưng tập tiểu cầu

Mục tiêu: Mô tả một số đặc điểm lâm sàng, cận lâm sàng ở bệnh nhân thở máy xâm nhập do hội chứng suy hô hấp cấp tiến triển (ARDS). Khảo sát biến đổi các chỉ số cơ học phổi và khí máu động mạch sau sử dụng thuốc giãn cơ ở bệnh nhân thở máy xâm nhập do ARDS.
Đối tượng và phương pháp nghiên cứu: Thiết kế nghiên cứu mô tả cắt ngang có theo dõi dọc trên 32 bệnh nhân được chẩn đoán ARDS mức độ trung bình – nặng (Berlin 2012); thở máy xâm nhập với chiến lược bảo vệ phổi và sử dụng giãn cơ theo phác đồ của Bộ Y tế. Lấy số liệu tại 3 thời điểm: trước khi sử dụng giãn cơ (T0), sau 1 giờ (T1) và sau 6 giờ (T2) sử dụng giãn cơ. Thời gian tiến hành nghiên cứu từ tháng 02/2022 đến tháng 12/2023.
Kết quả: Nam giới chiếm 68,8%; độ tuổi trung bình nhóm nghiên cứu là 54,53 ± 17,09; bệnh nền nhiều nhất là đái tháo đường típ 2 (25%). Căn nguyên ARDS chiếm nhiều nhất là viêm phổi (59,4%). Độ nặng theo APACHE II là 16,75 ± 5,68 điểm. Ppeak, Pplateau giảm và Compliance tăng có ý nghĩa thống kê (p < 0,05). PaO2 và P/F đều tăng có ý nghĩa thống kê (p < 0,05). SpO2 tăng và mạch giảm có ý nghĩa thống kê (p < 0,05). Thời gian sử dụng giãn cơ trung bình là 45,91 ± 25,23 giờ. Tỉ lệ tử vong là 41%.
Kết luận: Sử dụng giãn cơ trong thở máy xâm nhập điều trị bệnh nhân ARDS (với chỉ số P/F < 150) có hiệu quả cải thiện các chỉ số cơ học phổi (Ppeak, Pplateau, Compliance), cải thiện chỉ số oxy hóa máu (P/F), ổn định nhịp tim của bệnh nhân.
