Authors: Murharyana Murharyana , Al Ayyubi Ibnu Imam , Rohmatulloh Rifqi , Suryana Irfan
Published: October 2023

Tabligh Akbar has become a tradition that is inherent and ingrained in Indonesian society, in which there are strings of holy verses of the Qur'an and chanting blessings accompanied by melodious Islamic tones, which add to the specialness. This study used a qualitative method with a descriptive approach and ethnographic research. The data sources were taken from respondents in the form of several Darul Falah SMA students in grades X, XI, and XII, in which they are teenagers who often participate in Tabligh Akbar activities in various places, using data analysis techniques including data collection, data reduction, data display, and conclusion drawings or verification. In this study, it was found that Darul Falah High School students were in their teens and took part in the Tabligh Akbar to find identity and experience during the transition period, so that there was a comparison between the experience of academics in schools and religious experience in society, because there were still students who had not fully entered the formal operational stage, but still in the transitional stage from the concrete to the formal operational stage, the doctrines that were assimilated in the Tabligh Akbar activities and accepted by students can be realigned or classified as good and bad indicators with true religious lessons.

A New Experimental Investigation Of The High-Temperature Thermophysical Properties Of Metallic Powders
Authors: Berger Aaron , Ziesing Ulf , Benito Santiago , Weber Sebastian
Published: October 2023

PBF-LB/M is the most suitable process for the additive manufacturing with metallic powders when it comes to complex parts with geometrical accuracy. Nevertheless, some unknown variables are present in the process. Especially the thermal conductivity adds a high degree of uncertainty due to the significant influence of the heat flux from the part to the powder bed on the resulting properties of the part. A lack of experimental data addressing the thermophysical properties of powder and a deep understanding of the influences amplifies this problem. This work presents the thermophysical properties of different steel powders commonly used in the PBF-LB/M process using a newly developed powder container. In a quantitative comparative analysis with the corresponding solid materials, it could be shown that chemical composition and microstructure play a subordinate role in the resulting heat conductivity. Instead, the powder size distribution could be identified as the main parameter determining the emerging behavior.

Authors: Lindroos Tomi , Jokiaho Tuomas , Antikainen Atte , Lagerbom Juha
Published: October 2023

Nitrogen alloyed austenitic nickel-free stainless steel (ANFSS) is one of the most promising group of materials for consumer and health care products. They can be used to substitute not only conventional AISI 316L, but also titanium and Co-Cr alloys. Previously the utilization of nitrogen alloyed materials has been limited due to high work hardening rate. Recent developments in powder metallurgy, e.g., additive manufacturing (AM), are offering economically feasible net shape manufacturing routes to go around machining related problems. In the present study a viable processing route for ANFSS powder is introduced. It includes gas atomization and AM of test specimens by laser- and sinter-based methods. Special attention is paid on controlling the nitrogen content in different processing steps. The results show that by proper selection of processing parameters, the nitrogen content can be kept in desired level, thereby controlling the mechanical properties of ANFSS alloys.
Impact Of Saturation, Layer Thickness And Part Orientation On Green Strength In Metal Binder Jetting Additive Manufacturing Of Powder Feedstock Obtained From Spray Forming
Authors: Shang Naiqi , Dahmen Thomas , Lundin Christiansen Thomas , Karthik Nadimpalli Venkata
Published: October 2023

Low green strength of binder-jetted parts can lead to potential damage during depowdering and thus complicates green part handling. Understanding and optimizing green strength is therefore essential for the overall control and repeatability of the process. This study systematically investigates the effect of different saturation levels, layer thicknesses and part orientation on the mechanical properties, via compression testing, of binder-jetted cylindrical green parts. The results indicate excellent suitability of the spray-formed powder as binder jetting feedstock due to the uniform spherical particle morphology and high flowability. Mechanical testing indicated that higher binder saturation levels and loading direction perpendicular to the build direction are found to improve the compressive green strength, whereas the layer thickness only has a minor influence. The maximum compressive green strength was achieved as 7.67 MPa on average under the condition of 120% saturation and 90 µm layer thickness.
Use of high Melt Flow Rate Poly(oxymethylene) in Binders for Metal Injection Moulding Feedstocks
Authors: Boris Hein Sebastian , Min Doo-Sik , Luoto Mikael
Published: October 2023

Poly(oxymethylene) (POM) is widely used in for metal injection moulding (MIM) feedstocks, due to its high strength and clean removability. The intent to use high melt flow rate POM was to improve processability, enabling more intricate parts, or processing at lower process temperatures. The processability of different feedstocks, prepared with such a POM-type, was investigated regarding the effects of metal powder type (316L, 17-4 PH), particle morphology (gas- and water-atomized), as well as different mixing procedures (ZX-blade mixer with and without subsequent shear roll extrusion). Feedstocks of all variations could be processed properly, but the most promising results were shown by feedstocks using gas-atomized powders and both mixing procedures. In that case, due to the good flowability, the feedstock injection step was very smooth and led to the smallest process deviations. This was shown by analysing the process data and the characterization of green and sintered parts.
Energy Efficient Thermo-Fluid Dynamically Optimized High Temperature Vacuum Furnaces For Heat Treatment
Authors: Leitz Karl-Heinz , Valentini Bernhard
Published: October 2023

High temperature vacuum furnaces for heat treatment typically have operation powers of several hundred kilowatts. They are generally equipped with a fast-cooling system that has to assure that cooling rates, required for certain heat treatment processes, are uniformly met in the whole load. In this contribution thermo-electric and thermo-fluid dynamic analyses of a high temperature vacuum furnace with a refractory metal hot zone are applied to show potentials for energy savings without losing cooling efficiency. The simulation results are validated by experimental data. The results show that an optimization of the gas system allows energy savings of up to 20 % without losing cooling efficiency.
Diffusion Behavior of Carbon in Electro-Sinter-Forged Titanium
Authors: Recalcati S. , Denis G. , Mortensen A. , Fais A.
Published: October 2023

This work investigates the in-situ formation of TiC in titanium blended with carbon during Electro-Sinter-Forging (ESF) at different levels of Specific Energy Input kJ·g-1. When sintering powder mixtures of CP-Ti in compositions between 0.5 to 1%-wt graphite, carbon atoms diffuse and react with titanium to precipitate acicular or dendritic TiC in a near-fully to fully dense material. The shape of these precipitates evolves with increasing levels of energy from being finely dispersed sharp lamellae to a dendritic-like network. Understanding this behavior opens new possibilities to design novel reinforced Electro-Sinter-Forged titanium alloys or composites by precisely controlling the precipitated TiC shape and arrangement with a goal to optimize structural or functional properties of the material.
Environmentally Friendly Sintered Friction Materials For Clutch And Brake Systems
Authors: Walther G. , Trapp J. , Weißgärber T.
Published: October 2023

Sintered friction materials are used in particular for high performance applications due to their excellent temperature stability. Increasingly, new regulations regarding sustainability and environmental compatibility require innovative materials. In the USA, only brake pads with less than 0.5 percent may be sold by 2025 due to toxic abrasion. In addition, the new Euro 7 standard also imposes stricter limitations on non-exhaust particulate emissions. In this paper, material solutions for iron-based sintered linings for motorcycle brakes and synchronizer rings are discussed as an example of how to replace copper-based systems without losses in performance. Furthermore, the development of an aluminum composite brake disc is presented. These new brake discs use a particle-reinforced aluminum friction ring, which ensures an almost complete avoidance of the abrasion and, therefore, particle emission. Besides, the aluminum-based brake discs allow for lighter and more sustainable cars, e.g. by a 50 % reduction of the brake system’s weight.

Published: October 2023

The Additive Manufacturing (AM) process Laser Powder Bed Fusion (LPBF) makes it possible to produce Mo components with highly complex geometries in a resource-efficient way. Such complex components enable optimal functionalization and are of considerable industrial interest. The disadvantage of LPBF is that it is currently impossible to produce pure Mo components that achieve a similar strength and quality compared to their traditionally powder-metallurgically produced counterparts. Pure Mo components suffer from a coarse-grained, columnar, and cracked microstructure. Material adaptation to tolerate the unique solidification-boundary conditions in LPBF is necessary to improve component quality. In the present work, different alloying concepts to trigger grain refinement, to engineer grain boundary chemistry, and a combination of both are discussed. Furthermore, the effects on the microstructure and component quality are compared based on experimental results.
High nitrogen steels produced by PBF-LB/M – Process strategy and properties for ceramic additivated metal powders
Authors: Radtke Felix , Becker Louis , Herzog Simone , Lentz Jonathan , Weber Sebastian , Broeckmann Christoph
Published: October 2023

Additivated powders for powder bed fusion – laser beam (PBF-LB/M) process allow for innovative materials, which cannot be produced by conventional manufacturing techniques. In this study, Si3N4 powder is added to an austenitic steel powder for the manufacturing of high nitrogen steels (HNS). Therefore, two different types of additivation are investigated using tumbling mixers with and without grinding balls. Variations in the oxygen content and particle size distribution of the ceramic powder are analyzed to gain knowledge regarding influences on the rheological and reflective properties of the additivated powder. The flowability and packing density are determined as a function of humidity and drying parameters of the powder. The first samples of the investigated powders were processed by PBF LB/M. Microscopic investigation reveals new insights into the melting mechanisms of metal/ceramic mixtures. An analysis of the residual powder gives first indications regarding recyclability.

Published: October 2023

This work aims to compare the conventional powder metallurgy (PM), via Liquid Phase Sintering (LPS), with additive manufacture (AM), via L-PBF (Laser Powder Bed Fusion), considering WC cemented carbides and binders like Co, Ni and mixtures of Co and Ni. The mixtures were produced from dried slurries and some powder agglomeration was obtained with the use of organic binder. The great challenge was to improve flowability to obtain a bed as homogeneous as possible, so, additionally, a vibrating container was used to spread powder trying an uniform layer. Conventional samples were produced by press and high temperature vacuum sintering. For AM, laser power versus velocity were investigated. Microstructures were evaluated considering carbide distribution and the presence of cracks and porosities. The effects of different metallic binders were presented and discussed.

Published: October 2023

The fabrication of copper parts by 3D-extrusion of highly viscous paste was studied. This technology is classified as sinter-based AM technology. Extrusion-based 3D printing have been often reported in literature for production of ceramics components, however there are still few studies on metal components. 3D-extrusion allows printing of metallic components with a low anisotropy index, by deposition of layers of a paste composed of polymeric solution loaded with metal powder. In the present study, we evaluated the effect of paste composition on the microstructure and compressive strength behavior of copper parts. For that three different composition of water based polymeric pastes loaded with copper particles were prepared. Green parts were printed by paste extrusion at room temperature. Afterwards the parts were debinded and sintered. Extrusion-based 3D printing of metals pastes is an attractive route for cost effective production of small batches of complex shaped parts.

Vergangene Woche verständigte sich die Regierungskoalition auf ein Maßnahmenpaket zur Reform des Asylrechts, das medial vielfach unter dem Topos „schnellere Abschiebungen“ diskutiert wurde (siehe hier und hier). Die Änderungsvorschläge zeigen im Detail jedoch in sehr verschiedene Richtungen und enthalten sowohl Verschärfungen als auch punktuelle Erleichterungen. In Teilen sind sie rein symbolpolitischer Natur, enthalten aber auch spürbare Verschärfungen gegenüber Schutzsuchenden. Dabei simulieren die Vorschläge allerdings nur politische Handlungsfähigkeit und drohen gerade dadurch die Wahrnehmung politischer Lähmung zu verstärken.

Published: October 2023

COVID-19 and the “new normal” have come here to stay. What initially emerged as a local outbreak transitioned into a global pandemic, and has caused more than 6 million deaths.2 The sudden onset of the SARS-CoV-2 crisis challenged health care systems in terms of both patient overflow and information paucity. As the new infectious agent was previously unknown, evidence was scarce and highly controversial. Nonetheless, after the novel coronavirus continued spreading, medical literature became available to the point that more than 72,000 articles were published in PubMed in 2020 (Figure 1). This number is around 80 times greater than the previous year.
Ambliopía: revisión de lo básico a las nuevas líneas de investigación
Authors: Mendoza-Sigala Marcela
Published: October 2023

La ambliopía es un problema de salud pública que afecta de manera significativa la salud visual de la población a nivel mundial. Tradicionalmente, esta se define como una disminución de la agudeza visual en ausencia de anormalidades orgánicas demostrables del globo ocular.1 En la gran mayoría de los casos el defecto visual se encuentra confinado en un solo ojo (monocular). Sin embargo, existen algunos casos de afectación binocular.1 La importancia de esta patología radica en que es la primera causa de pérdida visual monocular en niños con una prevalencia aproximada del 1 al 6%. Como resultado de lo anterior, se estima que 2.9% de los casos de pérdida visual permanente en adultos son debidos a la ambliopía.1 Incluso, algunos autores la postulan como la primera causa de pérdida de visión durante los primeros 45 años de vida.2 Afortunadamente, si se detecta a tiempo, es posible revertirla en gran medida. Por lo anterior y por su efectos sociales y económicos significativos, existe un gran interés en la investigación de esta condición.

La medicina es una ciencia en constante crecimiento. Día tras día se descubren nuevos fármacos y terapias dirigidas. Ejemplo de ello son las nuevas terapias inmunológicas tipo check-point inhibitors (inhibidores del punto del punto de control inmunitario), los anticuerpos monoclonales para enfermedades reumatológicas y las terapias génicas para defectos congénitos. Sin embargo, en el área de la cardiología, el enfoque se ha centrado más que nada en el desarrollo de dispositivos de carácter biomédico para el tratamiento de la cardiopatía isquémica (stents, balones medicados) y estructural (oclusores, válvulas percutáneas, clips mitrales) y para las arritmias (marcapasos y desfibriladores implantables y subcutáneos). Desafortunadamente, la farmacología cardiovascular ha carecido de nuevas familias terapéuticas capaces de abordar la cronificación de las patologías cardiovasculares de mejor manera.1 Por lo tanto, sería interesante evaluar de manera más extensa el papel de los fármacos biológicos y las proteínas terapéuticas en cardiología. Un posible candidato sería el péptido natriurético auricular (ANP), el cual se ha reconocido por sus efectos beneficiosos en patologías como la falla cardiaca.2
Modeling Hartree-Fock approximations of the Schrödinger Equation for multielectron atoms from Helium to Xenon using STO-nG basis sets
Authors: Gangal Krish , Gerz pek , Goyal Tanvi , Iyer Ajeeth , Vaiyakarnam Vaibhav , McMahan Larry
Published: October 2023

The energy of an atom is extremely useful in nuclear physics and reaction mechanism pathway determination but is challenging to compute. Thus, we aimed to synthesize regression models for Pople Gaussian expansions of Slater-type Orbitals (STO-nG) atomic energy vs. atomic number scatter plots to allow for easy approximation of atomic energies without using computational chemistry methods. Using the Hartree-Fock method, we calculated atomic energies for elements helium to xenon (He to Xe) using STO-nG electron orbital basis set models. After calculating atomic energies for each basis set, we plotted them as tables of atomic energy (in Hartrees) versus the atomic number. We hypothesized that there would be a non-linear correlation in the scatter plot. We first formed the regressions using data from helium to krypton (He to Kr), and then we added new data from Kr to Xe. We then calculated the old and new coefficients of determination, and the difference between them. Due to their common use in modeling, exponential, sinusoidal, and quadratic regressions were tested to model the data. The data supported the hypothesis that the scatter plots had non-linear correlations. Sinusoidal and quadratic regressions had higher initial coefficients, suggesting higher viability, while sinusoidal regressions also had the highest average final coefficients, and the lowest change in coefficients. The data indicated that of the three regressions, sinusoidal regressions most aptly modeled the scatter plots.
Floating aquatic plants form groups faster through current
Authors: May Jiang , May Lili
Published: October 2023

Floating plants are plants that freely live on water without formal roots. Examples include Lemna minor and Lemna gibba (common name: duckweed). Duckweeds are often kept under conditions with no current to reduce stress; however, this may not always be beneficial. The purpose of this experiment was to determine whether water current, as an exogenous factor, can expedite duckweed integration after a stressor is applied. We hypothesized that duckweeds form a unified colony faster in a current-sustained environment than in motionless water. We found that colonies of duckweeds are formed through successive unifications of groups, mediated by the current. In fact, current flow disrupted and recreated the colony, which benefited the community because it reorganized and therefore enhanced both the diversity and the reproductive capability of the colony. In a current-disintegrating environment, the duckweeds never created a unified colony and rather formed small groups. The experiment demonstrated that floating aquatic organisms form communities faster in current-sustained environments than in environments where no visible current is present. These findings could have future implications in agriculture, conservationism, and artificial intelligence engineering.
Utilizing a novel T1rho method to detect spinal degeneration via magnetic resonance imaging
Authors: Wang David , Wang Ping
Published: October 2023

Spinal degeneration has been linked to critical conditions such as osteoarthritis in adults aged 40+; while this condition is considered to be irreversible, we took interest in magnetic resonance imaging (MRI) for early detection of the condition. Ultimately, our purpose was to determine the effectiveness of a relatively novel T1rho method in the early detection of spinal degeneration, and we hypothesized that the early to mild progression of spinal degeneration would affect T1rho values following an MRI scan. This research utilized increasing trypsin injection dosage (0.1–0.2 mL/kg), an enzyme known to artificially simulate spinal degeneration, in the discs of a swine spinal specimen (a standard spinal cord injury model) to observe the stages of spinal degeneration at a faster pace. As it is known that increased trypsin injections would directly advance spinal degeneration, we corresponded 0.1 mL/kg trypsin-treated discs to early degeneration and 0.2 mL/kg to mild degeneration. We then scanned the treated swine spine using MRI and analyzed its quantitative T1rho (spin-lattice relaxation time) values at advancing stages of spinal degeneration. We found that T1rho values from the MRI did increase from 0.1 mL/kg of trypsin (early degeneration) to 0.2 mL/kg (mild degeneration). We were able to identify a direct correlation between T1rho values and progressing stages of spinal degeneration. Because other methods such as T1 mapping, T2 mapping, and diffusion imaging have faced limitations in diagnosing spinal degeneration, this T1rho method could prove valuable to future research and diagnosis of spinal degeneration.

A retrospective observational study was undertaken to evaluate the clinical profile of recurrent urinary tract infections (UTIs) in a tertiary care hospital. Patients <18 years, kidney-transplant recipients, those on immunosuppressive agents and pregnant patients were excluded. Patients with ≥2 episodes of culture positive UTIs were included. Demographic details, investigations and treatment were recorded. Out of total 48 patients, 18 were female and 30 male. The common manifestations were acute pyelonephritis (52%), emphysematous pyelonephritis (20%) and cystitis (25%). Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (48%) was the most frequent organism isolated followed by Klebsiella spp. (29%) and Pseudomonas spp. (23%). Recurrent episodes of UTI with same organisms were noted in 62% patients. Death occurred in 12.5% patients due to septic shock. Renal calculi (24%) and double J (DJ) stent placement (30%) were associated with recurrent UTIs, though this was not statistically significant. Resistance to higher antibiotics (colistin, carbapenems, piperacillin-tazobactam, cefoperazone-sulbactam, third-generation cephalosporins) (65.4%, r = 0.81), diabetes (62.5%, r = 0.79), urological procedure (39.5%, r = 0.68), prior hospitalization (75%, r = 0.84), history of UTI prior to the study period (44%, r = 0.72) and need for per urethral catheter (PUC) beyond 7 days (35%, r = 0.74) had significant correlation with recurrent UTIs.

La conducta agresiva es un problema común en la infancia, afectando a muchos niños en todo el mundo. Esta actitud implica el uso de violencia física, psicológica o verbal, causando efectos negativos en su desarrollo personal y convivencia social. El objetivo del estudio fue reducir la conducta agresiva en estudiantes de primaria en una institución educativa en el norte de Perú. Se utilizó un programa de juegos sociales adaptado de Garaigordobil (2006), para desarrollar habilidades sociales en los niños. Se empleó el método hipotético deductivo con enfoque cuantitativo y diseño cuasi experimental, dividiendo a los estudiantes en dos grupos: el experimental, compuesto por niños agresivos de tercer grado B, y el grupo control, compuesto por niños de tercer grado A. Se midió la conducta agresiva verbal, física y psicológica utilizando un inventario basado en el test de Gosser (Candless, 1984), antes y después de la intervención. Se utilizaron pruebas estadísticas para evaluar la confiabilidad del instrumento y comparar los resultados entre los grupos. Antes de la intervención, se encontró que el nivel de agresividad era ligeramente mayor en el grupo control, pero no se encontraron diferencias estadísticamente significativas con un valor de p = 0,230, después de la intervención, los niveles de agresividad fueron menores en el grupo experimental en comparación con el grupo control, y esta diferencia fue estadísticamente significativa un valor de p=0,012, p<0,05. Los resultados mostraron que el programa de juegos sociales produjo un cambio significativo en los niños del grupo experimental, disminuyendo su conducta agresiva y aumentando su tolerancia, solidaridad, colaboración y respeto. Se recomienda a los docentes implementar este programa para mejorar el ambiente escolar y el aprendizaje de los estudiantes, y también se sugiere replicar esta investigación en otros estudios educativos.
Computerizing The Security of Ambiguity in Morphological Semantics
Authors: Al Dhaheri Wadima
Published: October 2023

What is not disputed is that language is the most prominent means of communication between different linguistic groups. Since all linguistic groups meet in the element of language, and among those languages is the Arabic language, which has a communicative system that makes it maintain an important place among the languages of the world, it is replete with its vocabulary that is truly capable of encompassing new and old meanings, and the Holy Qur’an has attested to this; By becoming aware of the vocabulary of the words of the Lord of the Worlds. Computational linguistics emerged as a result of the boom in computer science and artificial intelligence research that was primarily aimed at imitating and simulating the motor and mental processes practiced by advanced organisms such as humans. This ambiguity referred to has been termed in Arabic as ambiguity, and it is matched by the clear meaning that cannot be read beyond any interpretation, and it is the safest of ambiguity. This is what I present in this paper through investigation and understanding in this regard.
Tashen Corona: A Recasting of Hausa Traditional Pantomime by the COVID-19 Pandemic
Authors: Lawal Rabiatu
Published: October 2023

In 2020, the global pandemic impacted all areas of life, with the age long Hausa culture of tashe performance no exception. This culture is practiced during the Ramadan period and entails young men and women as well as children dressing up in comical costumes and going into houses to entertain inhabitants with melodies and drama and getting a token or grains in return. This cultural performance goes in tandem with contemporary issues in society; therefore modern day tashe is full of dramatic content reflecting contemporary events. Thus its coincidence with the COVID 19 pandemic was a recasting of the traditional pantomime to reflect the pandemic.
