The effect of beam width and crack-depth ratio on mode I fracture toughness of RCB: an experimental and numerical study
Authors: Ahmad Seleem , Gamiaa Ghada , El-Kholy Abd El-Monem 
Published: December 2023

In the present work, the fracture performance of pre-cracked reinforced concrete beams was investigated numerically and experimentally. Experimental and numerical programs were designed to examine the effect of beam width, b, (120 and 250 mm) and crack-to-depth ratio, a/d, (0.1, 0.2 and 0.3) for concrete strength, fc, (40 MPa), on the behavior of stress intensity factor, K1C, and fracture energy, G, for reinforced concrete, RC, beams. The work utilized beams with three-point loading conditions experimentally. Through the use of the ANSYS program, a comprehensive 3-D finite element analysis was conducted with utmost precision to simulate and idealize all experimental specimens. It has been confirmed through numerical and experimental outcomes that the stress intensity factor for RC concrete beams experiences a significant increase as the a/d increases. Furthermore, the fracture toughness values in this study show a slight increase due to the utilization of RC concrete beams with wider width. The validity of the presented concept was demonstrated by comparing the experimentally measured load vs. deflection values to the predicted numerical values and finding them to be acceptable.
Acercamiento a la objeción de conciencia desde el pensamiento filosófico de Ratzinger
Authors: Arranz Hierro Clara María 
Published: December 2023

El presente artículo trata de profundizar en la objeción de conciencia partiendo del pensamiento de Joseph Ratzinger, previo y contemporáneo a su etapa como romano pontífice (Benedicto XVI). La hipótesis de partida, que se ve refrendada en las conclusiones, es que la comprensión ratzingeriana de la conciencia, fundamentada en la verdad y en el bien, justifica la existencia de la figura de la objeción de conciencia como protección del contenido de aquella ante la imposición de cualquier norma, justa o injusta.
Para realizar esta investigación se ha abordado el estudio de todas las obras y discursos del autor que versan sobre la noción de conciencia, la objeción de conciencia y la verdad, y se ha consultado asimismo doctrina filosófica y jurídica en la materia.

Published: December 2023

Mahasiswa sebagai bagian dari civitas akademik memiliki tanggung jawab utama terhadap tugas akademiknya. Banyak ditemukan mahasiswa yang melakukan penundaan mengerjakan tugas akademik atau disebut dengan prokrastinasi akademik. Berbagai faktor yang menjadi penyebab mahasiswa keperawatan Poltekkes Kemenkes Semarang melakukan penundaan, salah satunya adalah faktor dalam individu itu sendiri atau disebut sebagai konsep diri. Penelitian ini disusun untuk mengetahui hubungan antara konsep diri dengan prokrastinasi akademik pada mahasiswa keperawatan Poltekkes Kemenkes Semarang. Jenis penelitian ini penelitian menggunakan metode korelasional dengan pendekatan cross sectional untuk mencari hubungan antara konsep diri dengan prokrastinasi akademik. Responden penelitian ini menggunakan sampel berjumlah 150 mahasiswa dengan teknik multistage random sampling yang memadukan teknik cluster sampling dan proportionate stratified random sampling . Variabel konsep diri diukur dengan kuesioner skala konsep diri yang berjumlah 25 item dan variabel prokrastinasi akademik diukur dengan kuesioner prokrastinasi akademik yang berjumlah 30 item. Kedua variabel dianalisis dengan uji korelasi Kendall Tau. Hasil analisis korelasi kedua variabel diperoleh hasil r= (-0,187) dengan Sig. (2-tailed) 0,002 (p<0,05), sehingga menunjukkan bahwa terdapat hubungan negatif yang signifikan antara konsep diri dengan prokrastinasi akademik mahasiswa. Artinya, apabila konsep diri mahasiswa meningkat, maka akan diikuti dengan perilaku prokrastinasi akademik mahasiswa yang menurun. Begitu pula sebaliknya, apabila konsep diri mahasiswa menurun, maka berpotensi terjadi peningkatan perilaku prokrastinasi akademik pada mahasiswa.
A Preliminary Investigation of a Hydrogen Injection Wedge Strut for a Scramject Combustor Application
Authors: Ruta Antonella 
Published: December 2023

<p>This M.Eng Report is a preliminary investigation of the strut geometry in a strut-based hydrogen scramjet combustor and assesses flow characteristics in an inviscid and viscid flow with no hydrogen injection, a viscid flow with hydrogen injection, and a viscid flow with hydrogen injection and combustion model. This investigation is performed using ANSYS Fluent. The viscid cases utilize the Shear Stress Transport (SST) k-omega model for turbulence, with the volumetric eddy dissipation model for combustion case. Results in this study are validated against the same wedge strut geometry and results from the Deutsches Zentrum für Luftund Raumfahrt (DLR) scramjet, by Waidmann [1], and a grid independence study is conducted for completeness. Performance of the different geometries are quantified by mixing efficiency, combustion efficiency, and total pressure recovery. The 2-dimensional results of this paper are comparable to the Schlieren images (shadow graphs) of the DLR combustor. </p>
<p>The viscid case with no hydrogen injection is compared to the inviscid case with no hydrogen stream, resulting in the presence of boundary layers and shear layers. This increased the strength and quantity of shock/expansion wave reflections downstream of the strut. The addition of the hydrogen stream increased the thickness of the central wake region along the combustor, further increasing strength of the shock reflections, as well as creating a symmetric recirculation region downstream of the strut. The eddy-dissipation combustion model is applied, resulting in a larger, non-symmetric recirculation region. The combustion efficiency reached 78.42% with complete mixing at 245 mm along the combustor, whereas the non-combusting case achieved complete mixing at 225 mm along the combustor. The high entropy caused by the irreversible processes across several strong shocks in the combustion case attributed to a total pressure loss of 46%.</p>
Tantalum-doped Mesoporous Bioactive Glass Fibers and Powders for Hemostatic Applications
Authors: Nagrath Malvika 
Published: December 2023

<p>Hemorrhage is the leading cause of battlefield deaths and second most common cause for civilian mortality worldwide, and mesoporous BGs (MBGs), are candidates for hemostasis. </p>
<p>Novel tantalum-containing MBG (Ta-MBG) powders: (80-<em>x</em>)SiO<sub>2</sub>-15CaO-5P<sub>2</sub>O<sub>5</sub>-<em>x</em>Ta<sub>2</sub>O<sub>5</sub> with <em>x</em>=0 (0Ta), 0.5 (0.5Ta), 1 (1Ta), 5 (5Ta), and 10 (10Ta), were developed using a sol-gel process. The powders were non-cytotoxic to bovine fibroblasts (MTT assay) and had a negative surface charge (-20.4 to -24.8 mV measured using zeta potential, ZP) which enhanced the intrinsic coagulation pathway (assessed using activated partial thromboplastin time, APTT). The powders (except 10Ta) showed lower hemolysis and APTT than ‘no treatment’ (physiological clotting). Among Ta-MBGs, 5Ta (11.6±5.8 sec) reduced APTT significantly compared to 1Ta (31.5±5.8 sec) and 10Ta (28±5.9 sec). Furthermore, lethal-liver-injury porcine trials of two best powders (5Ta and 1Ta) confirmed 5Ta as the most suitable composition for hemostasis. </p>
<p>Powder hemostats pose handling and functional challenges in the wet surgical field; to address these challenges, the hemostatic compositions (0Ta, 0.5Ta, 1Ta, and 5Ta) were fabricated as fibrous mats using a combination of sol-gel route and electrospinning technique. </p>
<p>The state-of-the-art analytical techniques showed fibers encompassing a hierarchical micro (0.5-2 µm) and nano (1-8 nm) porosity while the powders displaying unimodal mesopores (4 nm) leading to higher (298-374 m<sup>2</sup>g<sup>-1</sup>) surface areas than equivalent fibers (5-61 m<sup>2</sup>g<sup>-1</sup>). The ZP of the fibers (-26.2 to -48.7 mV) was better for hemostasis and stability in the wet environment than powders (-20.4 to -24.8 mV). The fibers were also non-cytotoxic to primary rat fibroblasts. The powders showed higher non-bridging oxygen-silicon (Si-NBO) bonds leading to higher ionic release than the fibers. Lower Si-NBO, lesser ionic release and more negative ZP provide advantageous stability to the fibers in wet environments. No significant differences between the bleeding times of powders and fibres was found using murine tail-bleed models. APTT suggested 1Ta composition to be most suitable among fibers to enhance hemostasis.</p>
<p>It is concluded that 5Ta and 1Ta provide the best compositions to enhance hemostasis among powders and fibers, respectively. The structural and functional differences/similarities of two forms were not reflected in their hemostatic capabilities. Finally, the fibers provide a stable matrix for clot formation that can compress the bleeding site.</p>

Thermal Analysis of Al and Cu Metals Heat Sinks with Different Geometries at Raspberry Pi Control Cards Used for Image Analysis-Based Drone Control in Smart Agriculture Drones
Authors: BEYAZ Abdullah 
Published: December 2023

A heat sink is a tool for dissipating the heat generated by electronic parts. The equipment's specific operating conditions necessitate the equipment's extra heat dissipation. This research compared and optimized the temperature and heat flux parameters based on the results of the design of a heat sink for CPU, RAM, and PCLe to a USB 3.0 bridge. It is aimed at an examination of the advantages and disadvantages of using square, rectangular, and circular shapes in the design of a heat sink. Copper and aluminum (Al) are the most common heat sink materials (Cu). Autodesk Inventor Pro software with Nastran module is used for design and thermal analysis.
According to Inventor Nastran's thermal analysis results it is found that there is no significant difference between Al and Cu materials based on cooling capacity at designed models. Also, it is found that the geometry of the heat sinks directly affects the cooling capacity of a heat sink.
The application results show that the cooling achievement is directly related to the correct heatsink design and enough surface area.

Material Analysis of a Sample Airless Wheel That Can Be Used in The Landing Gear of Small UAVs for Smart Agriculture Using the Finite Element Method
Authors: BEYAZ Abdullah 
Published: December 2023

Unmanned Aerial Vehicles (UAV) in categories 1 and 2 are small in size and have a maximum gross take-off weight between 5 - 40 N and 40 - 250 N, with a normal operating altitude of 120 m above ground level. One of the major concerns for UAVs is the weight of aerial vehicles, which is aided primarily by material changes. Tires for UAVs are primarily made of ABS, rubber silicone, and nylon to reduce flight problems. These tires add to the dead weight and drag during flight.
In response to these issues, a rigorous analysis was performed to select the best possible configuration using various materials such as Acrylonitrile Butadiene Styrene (ABS), rubber silicone, and nylon materials. UAV wheel manufacturing is commonly known as the production of high-strength light-weighing parts. It also provides a broader range of design options and favors an iterative design approach, so it is important the method of production. To achieve the best results, the iterative design approach was used in the analysis application. The study incorporated a design for airless tires with 40 spokes, leveraging Autodesk Inventor Pro for modeling. Subsequently, the designs underwent Finite Element Analysis to assess static radial strength. Bending and torsion stresses during landing were deemed negligible owing to the lightweight nature of categories 1 and 2 UAVs and were thus excluded from the analysis.
The modeled wheel design in Autodesk Inventor Pro analysis based on Finite Element Analysis of the airless wheels revealed that wheels made of rubber silicone exhibited superior shock absorption, with a deformation of only 2.314 mm at 625 N upon impact during UAV landing maneuvers.
