Abstract
Carrying capacity and environmental loads of coastal waters may have received less attention from development planners. Lift net fisheries, locally named bagan, has been growing rapidly in the coastal waters of Donggala Regency, Province of Central Sulawesi. This research was carried out to analyze the carrying capacity and environmental loads for controlling the expansion of bagan fisheries. This research was focused on the coastal waters of 19.53 km2 adjacent to Labean Village, Balaesang District. Measurements of aquatic environmental parameters were performed in-situ and water samples were collected in August to September 2018 for laboratory analysis. Analysis was carried out to determine locations that are environmentally suitable for bagan fisheries. and to calculate the maximum number of bagan that can be accommodated accordingly. All locations inside the study area are suitable for the fisheries. The maximum number of bagan varies with bagan sizes and their minimum gaps between the bagans (150m, 250m and 350m); 629 units for bagan of 7m x 7m with gaps od 150m or 231 units for bagan on 10m x 10m with gaps of 250m and 114 units for bagan of 20m x 20m with gaps of 350m.

Abstract

Bhenta-bhanto is local wisdom in catching octopus by fishermen from small islands in the Wakatobi Archipelago. This study aims to explain the mechanism of the bhenta-bhanto’s local wisdom and to find out the differences in fisherman income before and after the local wisdom is applied. The research occurred in Darawa Village, South Kaledupa District, Wakatobi Regency, Southeast Sulawesi, Indonesia. The research was conducted in March-December 2021. Research data were collected through observation, interviews, and literature study. Data were analyzed qualitatively and quantitatively using income analysis and Paired Sample T-Test. Based on the results of this study, it is known that the bhenta-bhanto is local wisdom in the form of an open and closed system for octopus fishing areas. The paired sample T-Test analysis shows differences in the income of octopus fishermen when the local wisdom of bhenta-bhanto is applied and when the local wisdom is not.
Development of the essential ecosystem area of Taman Kili-Kili Beach Trenggalek as a center for turtle conservation and ecotourism activities
Authors: Antriyandarti E , Ihsannudin  
Published: February 2023

Abstract
The Essential Ecosystem Area (EEA) of Taman Kili-Kili Beach, located in Trenggalek District (East Java), plays an essential role in preserving the biodiversity of protected animals, namely turtles, who play a significant role in maintaining the balance of marine ecosystems, starting from maintaining productive coral reef ecosystems to bringing essential nutrients from the ocean to the coast. This study aims to develop the EEA of Taman Kili-Kili Beach as a center for turtle conservation and an ecotourism destination to improve the community’s welfare while preserving the coastal and marine environment and the biodiversity of protected animals, especially turtles. This study uses a descriptive method to analyze the five forces model. The results show that the existence of turtle conservation will be a strength and attraction for tourists to visit EEA, especially for educational purposes and tourism on the beach. The main weakness is the lack of management of ecotourism support units such as souvenir centers, restaurants, and adequate rest areas. EEA of Taman Kili-Kili Beach can be developed by improving service and quality as an ecotourism destination and a turtle conservation center. This improvement also faces the threat of new entrants and substitutes and competes with competitors.

Abstract

Objective: To evaluate the effects of different sandblasting procedures on the wear and surface properties of zirconia and resin-based CAD/CAM restorative materials and to evaluate the relationships among materials and procedures. Materials and Methods: A total of 160 specimens of 2 mm thickness were prepared from Cerasmart, Vita-Enamic, Tetric-CAD, and Katana-Zirconia CAD/CAM materials. Each material was divided into four groups. Group-1: Control; Group-2: 29 μm Al2O3; Group-3: 30 μm CoJet; and Group-4: 50 μm Al2O3. Sandblasting procedures were applied from a distance of 10 mm for 15 s at 2 bar pressure. The volume loss resulting from sandblasting was calculated. The samples were then scanned with a Nanovea-PS50 non-contact profilometer. The Ra, Rz, and Sa values were recorded. The data were analyzed with the Shapiro-Wilk test and two-way ANOVA. Results: Group-4 showed the highest Ra and Rz values in all materials. The highest Sa and volume differences values were observed for Cerasmart, Vita-Enamic, and Tetric-CAD in Group-4; similar values were obtained for Katana-Zirconia. When the materials were compared, Cerasmart exhibited the highest volume differences, Ra, Rz, and Sa values in Group-4, while Katana-Zirconia demonstrated the lowest. Conclusions: Sandblasting procedure and material type showed a significant impact on the wear and surface properties. The abrasive effect increased with the increasing Al2O3 particle sizes for resin-matrix materials. Sandblasting with 50 μm Al2O3 exhibited the lowest wear and surface roughness values for Katana-Zirconia and the highest for Cerasmart.

Published: February 2023

AbstractThe study on polymethyl methacrylate (PMMA)-based composites in dental applications has gained much interest in recent years, resulting in many exciting studies worldwide. In those research, various filler types of reinforcing PMMA have been studied extensively. This study combines the microcrystalline cellulose (MCC) particles (0, 1, 2, 3, 5 vol.%) and sisal fiber to strengthen PMMA. We investigate their effects on the flexural, impact, hardness, compressive strength, water absorption, and thermal properties of (MCC)/sisal/PMMA hybrid composites. Scanning electron microscopy (SEM), universal testing machine (UTM), hardness Vickers, thermogravimetry analysis (TGA), and ANSYS Workbench 2022 R1 software are utilized to characterize the properties of the composites. X-ray diffraction (XRD) is used to characterize the degree of crystallinity of MCC and sisal fiber. Adding MCC to alkali-treated sisal/PMMA decreases the flexural and impact strengths but increases the hardness. Adding 1 and 2 vol.% MCC produces maximum flexural and impact strength and hardness values. Simulation on a composite added with 1% MCC by applying a full force load of 14.4 N yields compressive strength of 42.56 MPa. Thermal stability of all composites with and without MCC shows similarity until 250 °C but gradually degrades at over 250 °C, particularly for composites with MCC. Besides, as the addition of MCC increases, the water absorption also increases, with the lowest value of 37.54μg mm−3obtained by the composite added with 1 vol.% MCC, which is within the range of the standard dental materials.
Improved electrothermal performance of graphene-carbon nanotubes composite films utilizing AgNWs coating method

Published: February 2023

Abstract
A safe and high-performance electrothermal heater needs a lower operating voltage to produce heat for a long time and with high efficiency. The graphene-carbon nanotubes composite films and the AgNWs (siliver nanowires) dispersions were prepared and the AgNWs were successfully coated on to the composite films. The electrothermal performance of composite films with different carbon nanotubes (CNTs) contents, polymer additions and coating AgNWs were investigated. The maximum heating temperature decreases when the content of the polymer increases. In addition, the maximum temperature increases with the addition of CNTs. The sheet resistance gradually decreases with improving AgNWs coated amount and the sheet resistance changes little with the bending times on the whole. The microstructure of composite films coated with AgNWs revealed that AgNWs filled the holes on the surface of the composite films. Besides, the electrothermal efficiency, heating rate and cooling rate were significantly improved. For the electrothermal performance of the composite film coated with AgNWs only on the contact surface, the electrothermal efficiency, heating rate and cooling rate were also significantly improved compared with those of the composite films without an AgNWs coating. Therefore, composite film coating with AgNWs is one effective method to significantly improve the electrothermal performance for Gr composite film.

Abstract
Ultra-precision diamond cutting is a promising machining technique for realizing ultra-smooth surface of different kinds of materials. While fundamental understanding of the impact of workpiece material properties on cutting mechanisms is crucial for promoting the capability of the machining technique, numerical simulation methods at different length and time scales act as important supplements to experimental investigations. In this work, we present a compact review on recent advancements in the numerical simulations of material-oriented diamond cutting, in which representative machining phenomena are systematically summarized and discussed by multiscale simulations such as molecular dynamics simulation and finite element simulation: the anisotropy cutting behavior of polycrystalline material, the thermo-mechanical coupling tool-chip friction states, the synergetic cutting responses of individual phase in composite materials, and the impact of various external energetic fields on cutting processes. In particular, the novel physics-based numerical models, which involve the high precision constitutive law associated with heterogeneous deformation behavior, the thermo-mechanical coupling algorithm associated with tool-chip friction, the configurations of individual phases in line with real microstructural characteristics of composite materials, and the integration of external energetic fields into cutting models, are highlighted. Finally, insights into the future development of advanced numerical simulation techniques for diamond cutting of advanced structured materials are also provided. The aspects reported in this review present guidelines for the numerical simulations of ultra-precision mechanical machining responses for a variety of materials.
Improved inter-protein contact prediction using dimensional hybrid residual networks and protein language models
Authors: Si Yunda , Yan Chengfei 
Published: February 2023

AbstractThe knowledge of contacting residue pairs between interacting proteins is very useful for the structural characterization of protein–protein interactions (PPIs). However, accurately identifying the tens of contacting ones from hundreds of thousands of inter-protein residue pairs is extremely challenging, and performances of the state-of-the-art inter-protein contact prediction methods are still quite limited. In this study, we developed a deep learning method for inter-protein contact prediction, which is referred to as DRN-1D2D_Inter. Specifically, we employed pretrained protein language models to generate structural information-enriched input features to residual networks formed by dimensional hybrid residual blocks to perform inter-protein contact prediction. Extensively bechmarking DRN-1D2D_Inter on multiple datasets, including both heteromeric PPIs and homomeric PPIs, we show DRN-1D2D_Inter consistently and significantly outperformed two state-of-the-art inter-protein contact prediction methods, including GLINTER and DeepHomo, although both the latter two methods leveraged the native structures of interacting proteins in the prediction, and DRN-1D2D_Inter made the prediction purely from sequences. We further show that applying the predicted contacts as constraints for protein–protein docking can significantly improve its performance for protein complex structure prediction.

Abstract
The COVID-19 pandemic has affected all aspects of people’s lives worldwide, including the work of social workers and the education of social work students. Field placements are a significant part of social work education, but during the pandemic they were cut short and most teachings moved online. The current mixed methods study examined the effects of social work education on social work students’ empathy and resilience during the COVID-19 pandemic on the island of Ireland. A matched sample of forty-nine students completed an online survey at the start (T1) of their degree and at the end (T2). A further 229 students who only completed the T1 survey were compared to 70 others who only completed the T2 survey. The results showed improved resilience in the cohort comparison. There were no differences in empathy in the matched sample nor between the cohorts. Thematic analysis of students’ narratives showed that they found the switch to online learning difficult, with some reporting negative impacts on their mental health and the abrupt ending of placements impacting their feelings of preparedness for practice. Implications of this study and future research areas are discussed.
The racialized celebrity other in perfume advertisements
Authors: McAllister Matthew P , Beykont Yasemin , Forde Sydney L 
Published: February 2023

Abstract
Despite significant scholarship on the semiotics and ideology of perfume advertising, its racialized nature is underexamined. This is surprising given perfume-ad characteristics that incentivize racialized representations, especially ads using celebrities, and racist constructions of smell and scent. Using critical advertising studies, sensory studies, and bell hooks’ concept of the racialized Other, this article argues that perfume ads are markedly racialized. The racial semiotics of 10 print ads—five with BIPOC celebrities and five with White—are critiqued, with BIPOC celebrities essentialized as inherently exotic, wild, and primitively sexual, while White celebrities symbolize elegance, classic beauty, and uniqueness.

AbstractCRISPR-Cas systems provide heritable acquired immunity against viruses to archaea and bacteria. Cas3 is a CRISPR-associated protein that is common to all Type I systems, possesses both nuclease and helicase activities, and is responsible for degradation of invading DNA. Involvement of Cas3 in DNA repair had been suggested in the past, but then set aside when the role of CRISPR-Cas as an adaptive immune system was realized. Here we show that in the model archaeon Haloferax volcanii a cas3 deletion mutant exhibits increased resistance to DNA damaging agents compared with the wild-type strain, but its ability to recover quickly from such damage is reduced. Analysis of cas3 point mutants revealed that the helicase domain of the protein is responsible for the DNA damage sensitivity phenotype. Epistasis analysis indicated that cas3 operates with mre11 and rad50 in restraining the homologous recombination pathway of DNA repair. Mutants deleted for Cas3 or deficient in its helicase activity showed higher rates of homologous recombination, as measured in pop-in assays using non-replicating plasmids. These results demonstrate that Cas proteins act in DNA repair, in addition to their role in defense against selfish elements and are an integral part of the cellular response to DNA damage.
‘Queering the Textual Politics of Alba de Céspedes’s Prima e dopo’
Authors: Gabriele Tommasina 
Published: February 2023

Abstract
Alba de Céspedes’s Prima e dopo (1955) has generally been interpreted within the framework of the Italian Resistance and the subsequent disillusionment of Resistance ideals. While taking this interpretation into account, I argue that the central narrative of desire in Prima e dopo is not Irene’s relationship with her lover, Pietro, but Irene’s subversive desire for her maid, Erminia. I analyse and challenge some of the mechanisms and methodologies of Italian literary historiography that create and reproduce the disregard and devaluation of queer desire, specifically lesbian desire, in Italian narratives, and I identify scholarly, cultural and textual mechanisms that have rendered queer desire in Prima e dopo invisible. In sum, this article contributes to an Italian lesbian archive and lesbian literary historiography and argues that a queer reading of Erminia’s role in Prima e dopo enhances our understanding of the post-Resistance framework of the novel and its radical politics.
Chromosome-level genome and the identification of sex chromosomes in Uloborus diversus
Authors: Miller Jeremiah , Zimin Aleksey V , Gordus Andrew 
Published: February 2023

Abstract
The orb web is a remarkable example of animal architecture that is observed in families of spiders that diverged over 200 million years ago. While several genomes exist for araneid orb-weavers, none exist for other orb-weaving families, hampering efforts to investigate the genetic basis of this complex behavior. Here we present a chromosome-level genome assembly for the cribellate orb-weaving spider Uloborus diversus. The assembly reinforces evidence of an ancient arachnid genome duplication and identifies complete open reading frames for every class of spidroin gene, which encode the proteins that are the key structural components of spider silks. We identified the 2 X chromosomes for U. diversus and identify candidate sex-determining loci. This chromosome-level assembly will be a valuable resource for evolutionary research into the origins of orb-weaving, spidroin evolution, chromosomal rearrangement, and chromosomal sex determination in spiders.
Rationality of Real Conic Bundles With Quartic Discriminant Curve
Authors: Ji Lena , Ji Mattie 
Published: February 2023

Abstract
We study real double covers of $\mathbb P^{1}\times \mathbb P^{2}$ branched over a $(2,2)$-divisor, which are conic bundles with smooth quartic discriminant curve by the second projection. In each isotopy class of smooth plane quartics, we construct examples where the total space is $\mathbb R$-rational. For five of the six isotopy classes, we construct $\mathbb C$-rational examples with obstructions to rationality over $\mathbb R$, and for the sixth class, we show that the models we consider are all rational. Moreover, for three of the five classes with irrational members, we characterize rationality using the real locus and the intermediate Jacobian torsor obstruction of Hassett–Tschinkel and Benoist–Wittenberg. These double cover models were introduced by Frei, Sankar, Viray, Vogt, and the first author, who determined explicit descriptions for their intermediate Jacobian torsors.

AbstractObjectivesSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become established in the human population, making the need to develop safe and effective treatments critical. We have developed the small-molecule antiviral ensitrelvir, which targets the 3C-like (3CL) protease of SARS-CoV-2. This study evaluated the in vitro and in vivo efficacy of ensitrelvir compared with that of another SARS-CoV-2 3CL PI, nirmatrelvir.MethodsCultured cells, BALB/cAJcl mice and Syrian hamsters were infected with various SARS-CoV-2 strains, including the ancestral strain WK-521, mouse-adapted SARS-CoV-2 (MA-P10) strain, Delta strain and Omicron strain. Ensitrelvir efficacy was compared with that of nirmatrelvir. Effective concentrations were determined in vitro based on virus-induced cytopathic effects, viral titres and RNA levels. Lung viral titres, nasal turbinate titres, body-weight changes, and animal survival were also monitored.ResultsEnsitrelvir and nirmatrelvir showed comparable antiviral activity in multiple cell lines. Both ensitrelvir and nirmatrelvir reduced virus levels in the lungs of mice and the nasal turbinates and lungs of hamsters. However, ensitrelvir demonstrated comparable or better in vivo efficacy than that of nirmatrelvir when present at similar or slightly lower unbound-drug plasma concentrations.ConclusionsDirect in vitro and in vivo efficacy comparisons of 3CL PIs revealed that ensitrelvir demonstrated comparable in vitro efficacy to that of nirmatrelvir in cell culture and exhibited equal to or greater in vivo efficacy in terms of unbound-drug plasma concentration in both animal models evaluated. The results suggest that ensitrelvir may become an important resource for treating individuals infected with SARS-CoV-2.
