On the mechanism of piezoresistance in nanocrystalline graphite
Authors: Kumar Sandeep , Dehm Simone , Krupke Ralph
Published: April 2024

Strain sensors are sensitive to mechanical deformations and enable the detection of strain also within integrated electronics. For flexible displays, the use of a seamlessly integrated strain sensor would be beneficial, and graphene is already in use as a transparent and flexible conductor. However, graphene intrinsically lacks a strong response, and only by engineering defects, such as grain boundaries, one can induce piezoresistivity. Nanocrystalline graphene (NCG), a derivative form of graphene, exhibits a high density of defects in the form of grain boundaries. It holds an advantage over graphene in easily achieving wafer-scale growth with controlled thickness. In this study, we explore the piezoresistivity in thin films of nanocrystalline graphite. Simultaneous measurements of sheet resistance and externally applied strain on NCG placed on polyethylene terephthalate (PET) substrates provide intriguing insights into the underlying mechanism. Raman measurements, in conjunction with strain applied to NCG grown on flexible glass, indicate that the strain is concentrated at the grain boundaries for smaller strain values. For larger strains, mechanisms such as grain rotation and the formation of nanocracks might contribute to the piezoresistive behavior in nanocrystalline graphene.

Published: April 2024

La cría de cuyes (Cavia porcellus), es una actividad económica y culturalmente importante en el Ecuador y otros países latinoamericanos, especialmente en las zonas rurales. Este estudio se centra en evaluar los efectos de tres métodos de esterilización sobre el comportamiento reproductivo de cuyes machos. Se seleccionaron cuarenta y ocho cobayas macho, se dividieron en cuatro grupos y se asignaron aleatoriamente a tres tratamientos de esterilización diferentes junto con un grupo de control. El tratamiento consistió en la aplicación de una tintura de yodo al 1,3% en cada testículo, la aplicación intratesticular de ácido láctico al 10% y la extirpación de las apófisis estiloides o espículas del glande del pene. El tratamiento fue precedido por un período de adaptación de 15 días durante el cual se marcaron a los animales y se les administraron medicamentos antihelmínticos. Los resultados se analizaron mediante observaciones diarias durante 90 días registrando el comportamiento reproductivo de los machos en presencia de las hembras. Se encontraron diferencias significativas en el número promedio de paseos registrados por los animales en cada tratamiento. Observamos que los animales que se sometieron a esterilización química tuvieron una disminución significativa en el deseo sexual con el tiempo, mientras que los animales del grupo de control y los animales a los que se les extirpó la columna del pene mostraron un comportamiento similar. Estos resultados sugieren que los diferentes métodos de esterilización influyen significativamente en el comportamiento reproductivo de los cobayas macho. Estos resultados tienen implicaciones importantes para el manejo de las poblaciones reproductoras en la cría de cuyes y para la selección de los métodos más apropiados en términos de bienestar animal y eficiencia reproductiva.

Published: April 2024

A topological index is a number generated from a molecular structure that signifies the molecule’s fundamental structural characteristics. This correlation between the index and various physical attributes is based on an algebraic quantity related to the chemical structure. Many topological indices, such as the Wiener index, first and second Zagreb indices, can be employed to determine various properties, including chemical activity, thermodynamic properties, physicochemical activity, and biological activity. Meanwhile, the p-subgroup graph of a group G is defined as a graph whose vertices represent the elements of the group, and two vertices are adjacent if and only if the order of the subgroup is a prime power. The main objective of this paper is to establish the general formula for certain topological indices, specifically the Wiener index, first Zagreb index, and second Zagreb index for the -subgroup graph associated with dihedral groups.

Signal Processing Techniques of Lamb Waves for Structural Health Monitoring System - A Review
Authors: Nurazima Ismail  , Mohd Hafizi Zohari  , Che Ku Eddy Che Ku Nizwan  , Kok Sing Lim
Published: April 2024

The structural health monitoring (SHM) system using Lamb wave approach has drawn a lot of interest because of its outstanding performance in terms of accuracy and adaptability. The implemented signal processing techniques in the diagnostic analysis are specifically reviewed in this work. The primary factors of the wide range of applied signal processing techniques are due to the multimode and dispersive behaviour of the Lamb waves. Several Lamb modes occur simultaneously, and because they have different dispersive characteristics, they can produce complicated superimposed signals. To effectively diagnose the observed signals, several mode separations approaches have been proposed. Generally, time-frequency representation is applied for signal processing techniques. The findings demonstrated that the proposed procedures were successful in decomposing the superimposed mode into individual modes for further analysis. All these works have shown how SHM systems based on Lamb waves have evolved over time to control and monitor the condition of the structure.

Shoreline change poses a significant challenge in coastal regions, leading to issues such as abrasion, soil erosion, and the loss of valuable land. This problem is prevalent in various areas of Pangandaran, particularly in the Batu Hiu-Bojong Salawe coastal region of Pangandaran Regency, West Java, Indonesia. The objective of this study is to analyse and quantify the distance and rate of shoreline changes occurring over a decade (2010-2019) in the Batu Hiu-Bojong Salawe coastal area. Utilizing ArcMap software and the Digital Shoreline Analysis System (DSAS), this research aims to provide insights into the coastal dynamics, drawing analytical points from comparable studies for a comprehensive understanding. Batu Hiu's western coast faces substantial erosion (29.70m, LLR 3.10 m/year, EPR 3.22 m/year), while the east experiences accretion (52.76m, LLR/EPR 5.49 m/year, 5.72 m/year). Coastal dynamics, influenced by rocky structures, lead to sedimentation and erosion. Bojong Salawe Beach sees noteworthy accretion (83.01m, LRR/EPR 8.88 m/year, 9.00 m/year), with a maximum at transect 85 (134.5m, LRR 14.27 m/year, EPR 14.58 m/year). Erosion at transects 104 and 107 averages 30.47m, with LLR/EPR rates of 3.41 m/year and 3.3 m/year. The Cijulang River estuary contributes to coastal stability, resulting in significant accretion. This information is vital for coastal management, offering insights to address erosion and accretion impacts in Batu Hiu and Bojong Salawe coastal areas.
Mixed Convection Boundary Layer Flow over a Horizontal Circular Cylinder in AL2O3-Ag/Water Hybrid Nanofluid with Viscous Dissipation
Authors: Eddy Elfiano  , Nik Mohd Izual Nik Ibrahim  , Muhammad Khairul Anuar Mohamed
Published: April 2024

This paper investigated the mathematical modelling for mixed convection boundary layer flow over a horizontal circular cylinder in hybrid nanofluid with viscous dissipation. The transformed partial differential equations (PDEs) are numerically solved using an implicit finite-difference approach known as the Keller-box method. The numerical solutions for the reduced Nusselt number, , local skin friction coefficient, , temperature profile, and velocity profiles are found and graphically presented in detail. Effects of the Eckert number, Richardson number and nanoparticle volume fraction are all examined and explained. It is found that the increase of volume fraction of nano material in nanofluid has increased the value of skin friction coefficient. The low density of nano oxides such as alumina in hybrid nanofluids also contribute to reduce friction between fluid and body surface. Based on numerical analysis, the combination of nanoparticles in the form of hybrid nanofluid may reduce skin friction phenomena while sustaining heat transfer characteristics comparable to nanofluid. The results in this paper are original and will assist researchers working in the field of boundary layer flow. It can also be utilised as a reference in experimental studies to reduce operating costs.

Authors: Muhammad Al,Ain Mat Zin  , Izuan Amin Ishak  , Mohammad Arafat  , Nor Afzanizam Samiran  , Norain Sahari
Published: April 2024

Performance for Horizontal Axial Wind Turbine (HAWT) is influenced by the difference in tip speed ratio (TSR) and mesh distribution. The objective of this article is to study the optimal performance of wind turbines when subjected to different mesh resolution, TSR and wind speed velocity.Therefore, it is important to study the effects of different mesh resolutions in terms of wind turbine performance. To achieve that, a 0.65m optimal twist and tapered (OPT) blade is used with various inlet velocities and TSR. This study uses the k-ꞷ shear-stress transport (SST) based Reynold-Average Navier Stokes (RANS) approach in commercial ANSYS Fluent CFD software. This simulation was performed using the Moving Ratio Frame (MRF) method. To find the optimum grid resolution, a Grid Independence Test (GIT) was conducted comparing the coefficient of power (Cp). From the RESULT, TSR 6 shows the best HAWT performance when Cp for inlet velocity 8 m/s is 0.2608.
Numerical Prediction of Trailing Edge Noise at Low Reynolds Number with Modified Trailing Edges of a NACA 0015 Airfoil
Authors: Mohamed Ibren  , Amelda Dianne Binti Andan  , Waqar Asrar
Published: April 2024

Global concern about high noise levels in areas near airports and wind farms has generated interest from various groups due to factors such as potential health problems and dissatisfaction among the local community. To accommodate this worthwhile plan of further reducing overall noise levels, some researchers are working on lowering the contribution of trailing-edge noise. The original scientific contribution of this study lies on understanding the efficiency of various trailing edge designs such as baseline, serrations, comb and comb-serrated, across different angles of attack and Reynolds numbers, while also addressing the limitations of existing geometrical models for trailing edges. The study intends to examine the performance of these different configurations, with an emphasis on their effect on acoustic responses. By utilizing large-eddy simulation and applying the Ffowcs-Williams and Hawkings models for noise prediction, an investigation was conducted to assess the impact of these trailing edge configurations on radiated noise at a low Reynolds number of 1.6× 105. The numerical predictions of lift coefficient and surface pressure fluctuations are compared and validated with a published study and experimental data, showing satisfactory results. Further analysis of these study has demonstrated that prominent peaks at lower frequencies (<103) are observed, which are identified as the characteristic frequencies. Moreover, results showed irregular broadband noise (300 - 600 Hz) with increased noise and shifting peak frequency as angle of attack rose. The serrated trailing edge design notably reduced noise levels by roughly 21 dB, especially for low frequencies. Comb-serration increased high-frequency noise by about 9 dB for angles of attack at 0, -1, and -20, and achieved a reduction of approximately 9 dB for angles of attack at 1 and 20. On the other hand, the directivity pattern showed that the maximum noise level is observed to predominantly radiate at an azimuth angle of around 90 degrees for all the cases, ranging from 900 to 2700, indicating that the majority of the source's acoustic energy is being emitted on the suction and pressure sides of the airfoil.

Sowohl die anfängliche Nietzsche-Rezeption in Skandinavien als auch Nietzsches anschließende Begegnung mit August Strindberg wurden an den Rand der Geistesgeschichte gedrängt. Nietzsche’s Ocean, Strindberg’s Open Sea
ordnet diese Ereignisse in die Debatten über Nihilismus und Moderne des späten 19. Jahrhunderts ein und fragt, ob diese Themen auch im ersten Jahrzehnt des 21. Jahrhunderts noch aktuell sind.
Der erste Abschnitt des Buches befasst sich mit den Debatten im Vorfeld, während und unmittelbar nach den Nietzsche-Vorlesungen von Georg Brandes, die er im Frühjahr 1888 gegeben hat. Der zweite Abschnitt
erzählt die Geschichte von Strindbergs Briefwechsel mit Nietzsche und untersucht die philosophischen Fragen, die diese Begegnung aufgeworfen hat, wobei gelichzeitig ihre Implikationen für unser Verständnis
vorpsychoanalytischer Subjektivitätstheorien hervorgehoben werden.

The food sector has seen a significant transformation towards automation, resulting in remarkable improvements in efficiency and production. Nevertheless, this process of development poses a significant challenge in reproducing the sensory subtleties that are inherent in conventional, handcrafted food products. The manifestation of this difficulty is particularly apparent within the domain of cherished gastronomic staples such as pickles. Consumers worldwide possess a profound inclination towards the unique flavor, consistency, and fragrance of handmade pickles, attributes that are sometimes elusive to automated manufacturing methods. This research presents a novel approach to address the challenge of automated pickle manufacturing. The objective of our study is to establish a connection between the efficient production methods used in contemporary food manufacturing and the preservation of the sensory appeal that is inherent in traditional handmade pickles. The "Pickle Palate" technology has been carefully designed to ensure the preservation of sensory qualities throughout the automated manufacturing process. The "Pickle Palate" system utilizes real-time data from a variety of sensors to perform predictive analytics in order to identify sensory qualities and quickly adjust manufacturing processes. The basis of this undertaking is rooted in an extensive examination of scholarly works, focusing on the pivotal points of automated food manufacturing, sensory evaluation, and the need to achieve a nuanced equilibrium between mechanization and sensory authenticity. This investigation reveals a significant scientific deficiency, namely the lack of an automated method that can accurately replicate the sensory intricacies of handmade pickles. Our research initiative crosses multifarious areas, from the critical significance of sensory analysis in automated food production to the subtleties of real-time sensory assessment and taste profiling across varied culinary worlds. Delving further, the study delineates our suggested technique, defining the subtleties of data gathering, preprocessing, feature extraction, and a holistic approach to retaining sensory qualities – therefore ensuring a steady supply of premium-quality pickle products. In the accompanying discourse, we give convincing data exhibiting the system's adeptness in recreating sensory qualities, flawlessly harmonizing with human sensory assessments. Moreover, the real-time adjustments executed by our system yield pickles imbued with the desired sensory characteristics, heralding a monumental breakthrough that harmonizes automation with sensory precision – a testament to our unwavering commitment to cater to the discerning palates of consumers worldwide.

Skin microbiota is an integral part of the human immune system. Staphylococcus aureus is one of the essential components of the normal flora. Approximately 20–30% of healthy individuals are persistently colonized with S. aureus, whereas the remainders are considered low-level intermittent carriers. Despite these natural aspects of existence, S. aureus can be a major opportunistic human pathogen. This versatile microorganism can infect a variety of anatomical sites, causing a broad spectrum of pathologies ranging from superficial to invasive infections. It developed a variety of strategies to adopt to a changing microenvironment. This attributed to the emergence of resistance to antibiotics of different classes during the past six decades. Methicillin-resistant S. aureus (MRSA) was originally confined to health-care settings (health-care-associated MRSA). Later on, community-acquired MRSA was identified as another source of infections. Recent figures indicate that MRSA strains have been associated with approximately 75% of all S. aureus infections worldwide. Several guidelines have been published to establish an adequate treatment of skin and soft tissue infections (SSTIs) caused by MRSA strains. In the first part of this review, we focus on current treatment guidelines with a focus on medical drug therapy, but drug therapy has its own limitations. Recently, the interest in herbal remedies has greatly increased. There is growing evidence of antimicrobial activity of medicinal plants and their extracts. The second part of this review is dedicated to herbal compounds to circumvent antibiotic resistance. Herbal compounds may potentiate the action of antibiotics and restore the activities of antibacterial agents against which S. aureus has developed a drug resistance. Part 2 focuses on the role of S. aureus in pathology of the two major inflammatory skin diseases, i.e., atopic dermatitis (AD) and psoriasis. Finally, Part 3 provides an overview on natural compounds with antimicrobial activity against S. aureus and possible use in the treatment of SSTIs,
State of the surface waters in the Mesta River basin, after the reclamation of the Eleshnitsa uranium deposit

In the period from 1955 to 1992, uranium ore was mined and processed in the Mesta River basin around the village of Eleshnitsa, region of Razlog. The ore processing plant was built and a tailings storage facility was built next to it. In the period 2002–2006, the tailings storage was reclaimed, and in 2011–2012 the ore mines were also reclaimed. For the treatment of drainage water, a treatment plant was built in the valley of Valchoto Dere River, a left tributary of the Mesta River. The radiological monitoring carried out by the Basin Directorate “West Aegean Sea Region” reveals a generally good quality of the surface waters in terms of the content of uranium and radium (226Ra) outside the area of the former uranium mining and the tailings storage facility. In this area, in some years a high content of natural uranium was found, with concentrations from 0.54 to 67.40 mg/l on average per year. The values significantly exceed (by 1.8 to 224.6 times) the norm regulated in the regulation for radiation protection and safety from the liquidation of the consequences of uranium mining. The spread of uranium is limited to a small area shortly downstream from the sources of contamination, but the potential risk to the local ecosystem should not be neglected. Radium, in contrast to uranium, has concentrations below the permissible limits in the twelve years studied. Its content varied from 0.025 to 0.11 Bq/l on average annually. The results show that the Mesta River near the border with the Republic of Greece is not contaminated with the studied radionuclides.
Enjeux du numérique en théologie pastorale et en pédagogie religieuse
Authors: Amherdt François-Xavier
Published: April 2024

Comment le numérique et la promotion de l’image dans notre culture contemporaine modifient-ils non seulement les manières de vivre en Église, mais la manière de penser la foi et sa transmission ? C’est à un véritable bouleversement dans nos manières de penser, de communiquer, de former, de transmettre la foi et d’évangéliser, que le déploiement des technologies du numérique continue de nous conduire. C’est une sorte d’« écosystème digital » qu’elles établissent. La contribution prend en compte sept défis principaux qu’une e-pastorale et une « e-catéchèse holistique » s’emploient à relever à l’ère des « écologies digitales », du fait des modifications de nos rapports aux savoirs, à la vérité, à la temporalité, à l’autorité, à l’expérience spirituelle, à la pédagogie d’initiation et à la communauté. Ce sont des formes de combinaisons hybrides entre propositions pastorales et catéchétiques en présentiel et en ligne que nous sommes poussés à développer, car vu la loi de l’incarnation « synesthétique » au cœur de la foi chrétienne, le tout numérique demeure une illusion.
