High- and low-cycle-fatigue properties of additively manufactured Inconel 625
Authors: Concli Franco , Gerosa Riccardo , Panzeri Davide , Fraccaroli Lorenzo 
Published: January 2024

AbstractIn the last years, additive manufacturing has become a widespread technology which enables lightweight-design based on topological optimization. Therefore, generation of lattice structures with complex geometries and small thicknesses is allowed. However, a complete metallurgical and mechanical characterization of these materials is crucial for their effective adoption as alternative to conventionally manufactured alloys. Industrial applications require good corrosion resistance and mechanical strength to provide sufficient reliability and structural integrity. Particularly, fatigue behavior becomes a crucial factor since presence of poor surface finishing can decrease fatigue limits significantly. In this work, both the low-cycle-fatigue and high-cycle-fatigue behaviors of Inconel 625, manufactured by Selective Laser Melting, were investigated. Fatigue samples were designed to characterize small parts and tested in the as-built condition since reticular structures are usually adopted without any finishing operation. Microstructural features were studied by light-optical microscopy and scanning-electron microscopy. Finally, fatigue failures were deeply investigated considering fracture mechanics principles with the Kitagawa–Takahashi diagram.
Graphene-enhanced, wear-resistant, and thermal-conductive, anti-/de-icing gelcoat composite coating

Published: January 2024

AbstractWind power is considered as a sustainable and environmentally friendly energy source. However, the occurrence of icing poses significant challenges to energy production, particularly in frigid regions during the winter season. Conventional strategies employed for preventing and removing ice formation have proven inadequate due to their inability to satisfy intricate requirements or their high energy consumption. In this study, a commercial gelcoat coating was adopted as an anti-/de-icing coating by introducing different concentrations of graphene and boron nitride into the gelcoat coating through physical mixing. Extensive investigations were conducted on the correlation between anti-/de-icing, wear resistance, and thermal conductivity. Notably, the incorporation of nanoparticles induced a rise in the surface roughness, resulting in prolonged resistance to water icing on the coated surface. The wear resistance and thermal conductivity of the composite coating were enhanced through the inclusion of boron nitride and graphene. The building of thermal conductive particle networks improved thermal conductivity which can lead to improved heat transfer and heat distribution. At the same time, the enhanced gelcoat composite coating exhibited exceptional passive anti-/de-icing performance and wear resistance. This coating can replace commercial coatings to improve anti-/de-icing efficiency for the existing active heating anti-/de-icing techniques available in the market.

The graphene was employed to enhance the thermal conductivity, wear resistance, and anti-/de-icing properties of the turbine coating.

AbstractBiochar and organic fertilizer are widely supported to maintain crop production and sustainable development of agroecosystems. However, it is unclear how biochar and organic fertilizer alone or in combination regulate soil functional microbiomes and their relationships to ecosystem multifunctionality (EMF). Herein, a long-term (started in 2013) field experiment, containing five fertilization treatments, was employed to explore the effects of biochar and organic fertilizer applications on the EMF (based on 18 functional indicators of crop productivity, soil nutrient supply, element cycling, and microbial biomass) and the functional microbiomes of bulk soil and rhizosphere soil [normalizing the abundances of 64 genes related to carbon (C), nitrogen (N), phosphorus (P), and sulphur (S) cycles]. Compared with single-chemical fertilization, biochar and organic fertilizer inputs significantly enhanced most ecosystem-single functions and, in particular, the EMF significantly increased by 18.7–30.1%; biochar and organic fertilizer applications significantly increased the abundances of soil microbial functional taxa related to C-N-P-S cycles to varying degree. The combined application of biochar and organic fertilizer showed a better improvement in these indicators compared to using them individually. Most functional microbial populations in the soil, especially the taxa involved in C degradation, nitrification, nitrate-reduction, organic P mineralization, and S cycling showed significantly positive associations with the EMF at different threshold levels, which ultimately was regulated by soil pH and nutrient availability. These results highlight the strong links between soil microbiomes and agroecosystem functions, as well as providing scientific support for inclusion of biochar in agricultural production and services with organic amendments.

Influence Maximization in Dynamic Networks Using Reinforcement Learning
Authors: Dizaji S. Haleh S. , Patil Kishor , Avrachenkov Konstantin 
Published: January 2024

AbstractInfluence maximization (IM) has been widely studied in recent decades, aiming to maximize the spread of influence over networks. Despite many works for static networks, fewer research studies have been dedicated to the IM problem for dynamic networks, which creates many challenges. An IM method for such an environment, should consider its dynamics and perform well under different network structures. To fulfill this objective, more computations are required. Hence, an IM approach should be efficient enough to be applicable for the ever-changing structure of a network. In this research, an IM method for dynamic networks has been proposed which uses a deep Q-learning (DQL) approach. To learn dynamic features from the network and retain previously learned information, incremental and transfer learning methods have been applied. Experiments substantiate the good performance of the DQL methods and their superiority over compared methods on larger sizes of tested synthetic and real-world networks. These experiments illustrate better performance for incremental and transfer learning methods on real-world networks.
Agile by accident: how to apply Agile principles in academic research projects
Authors: Biely Katharina 
Published: January 2024

AbstractSustainability science and sustainability transition studies are interdisciplinary fields. Interdisciplinarity is understood to support out-of-the-box thinking and thus facilitate scientific advancements. Interdisciplinary research projects dealing with complex issues might need project management approaches that support learning, adaptation, and innovation. Agile is a management approach that has been developed to facilitate collaboration, learning, creativity, innovation, and reflectivity. Due to these qualities, Agile might be a suitable approach to managing interdisciplinary research projects. Agile project management is still new in academic research settings. Only limited information about how to apply it in an academic setting exists. To fill this gap the Agile principles are translated to fit the academic context. The article then outlines how Agile principles can be applied to an academic research program, that did not consciously plan to apply this approach. The translation of the principles will permit other researchers to intentionally use them in their interdisciplinary research projects. Furthermore, other researchers can build on the insights provided in this article to overcome the challenges that Agile can bring.

Should we develop AGI? Artificial suffering and the moral development of humans
Authors: Li Oliver 
Published: January 2024

Abstract
Recent research papers and tests in real life point in the direction that machines in the future may develop some form of possibly rudimentary inner life. Philosophers have warned and emphasized that the possibility of artificial suffering or the possibility of machines as moral patients should not be ruled out. In this paper, I reflect on the consequences for moral development of striving for AGI. In the introduction, I present examples which point into the direction of the future possibility of artificial suffering and highlight the increasing similarity between, for example, machine–human and human–human interaction. Next, I present and discuss responses to the possibility of artificial suffering supporting a cautious attitude for the sake of the machines. From a virtue ethical perspective and the development of human virtues, I subsequently argue that humans should not pursue the path of developing and creating AGI, not merely for the sake of possible suffering in machines, but also due to machine–human interaction becoming more alike to human–human interaction and for the sake of the human’s own moral development. Thus, for several reasons, humanity, as a whole, should be extremely cautious about pursuing the path of developing AGI—Artificial General Intelligence.
Best beaches of the world: a critique of web-based rating
Authors: de Oliveira Elaine Baroni , Newton Alice , Botero Camilo M. 
Published: January 2024

AbstractThis study analyzes the content of internet ratings of beaches to identify the indicators used. The methodology used an exploratory internet survey using the term ‘best beaches’ in five languages. For each site, the ranking method used was extracted and the indicators considered were listed, where applicable. Of the 70 websites analyzed, 47 ranked the beaches (67%) but less than 50% used indicators. The remaining were based on the opinion of the editorial board, personal experience, and users’ perceptions. The most used indicator was the color of water, followed by the color of the sand. These results show that the majority of ‘best beaches’ lists are based on subjective criteria. They are an overview of places that appeal to the person that wrote the page and are not scientifically or analytically based. Even when indicators are considered, these are mostly a reflection of the idea of an idealized beach, crystal blue waters with white or gold sand. The actual quality of the beach, including water quality, carrying capacity, and ecosystem balance, is not addressed. Although visual attractiveness is a key element for the public, these rankings should incorporate a wider range of indicators to fully assess the quality of a beach.

Published: January 2024

AbstractLung cancer, of which non-small-cell lung cancer (NSCLC) is the most common type, is the leading cause of cancer-related deaths. Anatomic pulmonary resection followed by adjuvant chemotherapy is considered the standard-of-care for patients with resectable NSCLC; however, postoperative relapses and metastases remain common. Immunotherapy, mainly with immune checkpoint inhibitors, has revolutionized the treatment of patients with metastatic NSCLC. In addition, it provides a new strategy for the perioperative treatment of resectable NSCLC. Initial encouraging results have been reported from clinical studies exploring different immunotherapeutic strategies for resectable NSCLC. This review summarizes the results of the latest clinical trials evaluating various perioperative immunotherapeutic approaches aimed at improving the outcomes of patients with resectable NSCLC.
An experimental investigation on the aerodynamic characteristics and vortex dynamics of a flying wing
Authors: Kumar V. , Mandal A.C. , Poddar K. 
Published: January 2024

AbstractIn this paper, we present a detailed experimental investigation mainly on the vortical flow fields and the associated vortex breakdown phenomena over a non-slender flying wing (sweep angle,
${\rm{\Lambda }}$
= 53°). In the process, the aerodynamic coefficients were also determined using a six-component force balance. Surface oil flow visualisation, surface pressure measurements and particle image velocimetry (PIV) measurements, in various crossflow planes and in a longitudinal plane passing through the leading-edge vortex core, were carried out at various Reynolds numbers to understand the flow field over the non-slender flying wing. Aerodynamic characteristics of the flying wing show local peaks and valleys in the pitching moment coefficient. The surface flow visualisation reveals that the nonlinearity of the pitching moment curve is due to the complex nature of vortical flow structures. The flow visualisation also demonstrates the presence of a wave-like surface pattern, and its size is found to reduce with increasing Reynolds numbers. The present PIV measurements confirm that this wave-like surface pattern is associated with vortex breakdown phenomena. These measurements also reveal that the vortex breakdown has not reached the apex of the wing, even at post-stall angle-of-attack. For pre-stall (
$\alpha $
= 20°) flow regimes, it is observed that the location of the vortex breakdown moves downstream as the Reynolds number increases, but this influence is minimised at near-stall (
$\alpha $
= 25°) and post-stall (
$\alpha $
= 30°) flow regimes. Reconstructed velocity field using the first 10 dominant proper orthogonal decomposition (POD) modes reveals that the nature of the vortex breakdown over the flying wing is a spiral-type vortex breakdown.

AbstractYoungia japonica (L.) DC. was recently discovered on the Azorean island of São Miguel. This species is a cosmopolitan herb that has been reported to be invasive in several regions of the world. It is unclear when and how this plant arrived in São Miguel, Azores. Nevertheless, we hypothesize that this is an unintentional and recent introduction. The populations are expanding in São Miguel, and action is needed to mitigate potential damage to native ecosystems.
Sour grapes and sweet harmony: Historicizing collective action problems in the South African wine industry
Authors: Nugent Paul 
Published: January 2024

AbstractThe article addresses how merchants and wine producers interacted while oscillating between competition and collaboration in their internal relations. Spanning a period of more than a century, it addresses three chronological periods: 1900–1940, 1940–1994, and 1994 to the present. In the first, producers were able to forge a common front against the merchants in the shape of the Koöperatieve Wynbouwers Vereniging van Suid-Afrika, which was granted devolved regulatory powers over distilling wine in 1924 and then all wine in 1940. In the second, the antagonism between good and distilling producers was sublimated at a time of relative prosperity, while the merchants engaged in fierce competition. In the final phase, the regulatory system imploded while the export market re-emerged. Quality producers found common ground in appealing to terroir, whereas marginal producers supplied merchants and supermarkets with low-priced bulk wines.
The Mustis arch and its dedication
Authors: Sánchez de la Parra-Pérez Santiago 
Published: January 2024

Abstract
The arch of Gordian III at Mustis (Al Karib, Tunisia) has been the subject of scholarly work since the eighteenth century, and its dedicatory inscription has drawn the attention of antiquarians and archaeologists since the early nineteenth century. The transcription and reconstruction of its text were proposed by the editors of the eighth volume of the Corpus Inscriptionum Latinarum in numbers 1577 and 15572. This version has prevailed in scientific literature ever since, even though Beschaouch announced in a short note in 1969 the discovery of a fourth block that substantially alters the information it contains. However, a comprehensive study of the complete inscription was never published due to the lack of graphic material. Thanks to the drawing by J. Vérité, the architect in charge of the monument's restoration, we can analyse the inscription as a whole. We conclude that the proposal by the CIL editors is incorrect, we provide the complete transcription of the epigraph, and we propose a new date for the dedication of the arch, in 240 AD.
Lactoferrin's potential application in enhancing yoghurt's microbial and sensory qualities, with emphasis on the starter culture activity
Authors: Nadi Walaa G. , Taher Eman M. , Awad Abeer Abdel Nasser , Ahmed Lamiaa Ibrahim 
Published: January 2024

AbstractThis research paper aimed to examine the antibacterial activity of lactoferrin (LF) as a potential natural alternative in the dairy sector, by measuring its minimum inhibitory concentration (MIC) against a number of common food-borne pathogens as well as Pseudomonas aeruginosa, one of the major dairy product spoiling microorganisms. Additionally, a viability experiment was applied to laboratory-manufactured set yoghurt to assess its impact on the activity of starter culture, sensory properties and STEC survivability. The findings demonstrated that LF exhibited significant antimicrobial activity, particularly against E. coli and S. typhimurium with MIC values of 0.0001 and 0.01 mg/ml, respectively. However, P. aeruginosa and B. cereus were quite resistant to LF requiring higher concentrations for MIC (2.5 mg/ml). By the third day of storage, LF at 0.0001 and 0.001 mg/ml significantly reduced the survivability of Shiga toxin-producing E. coli STEC by 70 and 91.6%, respectively, in the lab-manufactured yoghurt. Furthermore, LF enhanced the sensory properties of fortified yoghurt with a statistically significant difference in comparison to the control yoghurt group. There was no interference with the activity of the starter culture throughout the manufacturing process and the storage period. In conclusion, the potent antimicrobial effect of LF opens a new avenue for the dairy industry's potential applications of LF as a natural preservative without negatively influencing the sensory properties and starter culture activity of fermented products.

AbstractThe aim of this study was to evaluate the effect of the sprinkler cycle and flow rate on physiological, behavioural, and productive responses in dairy buffaloes. Nine Nili Ravi lactating buffaloes were subjected to three sprinkler cycles and two flow rates using a double replicated 3 × 3 Latin square design. The flow rates were 1.25 and 2 l/min, and the sprinkler cycles (minutes water on/off, number of cycles/h) were: 3/3, 10 cycles; 3/6, 7 cycles and 3/9, 5 cycles. The showering was applied from 0800 till 1630 h daily. In the first square of 21 d, each of the three sprinkler cycles was applied using a 1.25 l/min flow rate for 7 d per cycle. In the later square, the same treatments (sprinkler cycles) were applied using the 2 l/min flow rate. The average temperature humidity index during the study period was 85.7 ± 3.8 (Mean ± sd). The result showed that the 3/3 treatment group had lower body temperature and respiration rate than the other groups. The buffaloes in the 3/3 group produced 0.5 and 0.7 kg more milk with 1.4 and 2.4% more fat than the 3/6 and the 3/9 treatment groups, respectively. Similarly, the 2 l/min flow rate had a lower core body temperate and respiration rate and higher milk yield than the 1.25 l/min group. The 3/3 showering cycle with a 2 l/min flow rate appeared effective in improving physiological responses and milk yield in dairy buffaloes.
Lack of evidence for association between the leptin/Sau3AI gene and milk yield traits in Holstein Friesian dairy cattle
Authors: Kibar Mustafa , Aytekin İbrahim 
Published: January 2024

AbstractThis study aimed to investigate the effect of leptin gene polymorphism and some environmental factors on milk production traits. Blood samples from 212 Holstein Friesian dairy cattle reared on a private farm were used. The intron 2 region of the leptin gene was digested with Sau3AI restriction enzyme using the PCR-RFLP method. A and B alleles and AA, AB, and BB genotype frequencies for the Sau3AI polymorphism were determined as 0.8821 and 0.1179, and 0.764, 0.236 and 0.000, respectively. Chi-square analysis revealed that the leptin gene polymorphism followed the Hardy–Weinberg equilibrium, including the absence of animals with the BB genotype. The effect of leptin gene polymorphism on all milk production traits was insignificant. For milk production traits, direct heritability (ha2) varied between 0.03 ± 0.283 (for the dry period) and 0.50 ± 0.183 (for milk conductivity). Regarding the milking time (MT), the estimated breeding values (EBVs) of cattle with the AA genotype were higher than the AB genotype (P < 0.05). As a result of this study, in the selection program, allele or genotype could not be suggested as a marker for milk yield characteristics except for the possible exception of milking time and its relationship to mastitis incidence.
