Published: May 2023

The particle size of clastic sediments can provide important information about mechanisms of transport, selection and deposition which are related to the dominant hydrodynamic processes. This study describes the superficial sediments of ten intertidal plains located along the North (one site) and South (nine sites) Bays in Florianópolis, SC, where the clam Anomalocardia brasiliana is artisanally exploited. Systematic sedimentological sampling was carried out in all areas during the fall of 2008, summing up 464 samples. In the laboratory, samples were subjected to particle size analysis techniques. Sand was the predominant constituent in all banks analyzed, ranging from 70.59% in Maruim to 97.56% in Maciambú. Mean particle diameter varied from 1φ to 3φ in the study area, corresponding to medium to fine sands. Clay and silt attained higher percentages in Praia da Daniela bank, in North Bay, specially as compared to the banks located in the eastern and southern sectors of the South Bay. Such sediment distribution seems to be related to the more energetic characteristic of the South Bay as compared to the North Bay, where tidal and wind-induced currents are more gentle favouring the deposition of finer sediments.

Paulo Freire (1921-1997) criou um revolucionário método de alfabetização no qual o educando assimilaria o objeto de estudo, tendo como base as suas vivências, suas experiências de vida, ou seja, sua realidade. A teoria de Freire vai em contraposição a uma educação, por ele denominada bancária, tecnicista e alienante. Em contrapartida, o governo Bolsonaro não poupou críticas, comentários infundados, questionando o ensino freiriano. Pensando nisso, este artigo visa refletir acerca desse fenômeno, buscando analisar a motivação do governo eleito em 2018 em desmoralizar e difamar uma filosofia antifascista. Assim, as reflexões apresentadas aqui demonstram subsídios para discussões e possibilidades de mudanças na realidade brasileira.

Cloud object storage such as AWS S3 is cost-effective and highly elastic but relatively slow, while high-performance cloud storage such as AWS ElastiCache is expensive and provides limited elasticity. We present a new cloud storage service called ServerlessMemory, which stores data using the memory of serverless functions. ServerlessMemory employs a sliding-window-based memory management strategy inspired by the garbage collection mechanisms used in the programming language to effectively segregate hot/cold data and provides fine-grained elasticity, good performance, and a pay-per-access cost model with extremely low cost.
We then design and implement InfiniStore, a persistent and elastic cloud storage system, which seamlessly couples the function-based ServerlessMemory layer with a persistent, inexpensive cloud object store layer. InfiniStore enables durability despite function failures using a fast parallel recovery scheme built on the auto-scaling functionality of a FaaS (Function-as-a-Service) platform. We evaluate InfiniStore extensively using both microbenchmarking and two real-world applications. Results show that InfiniStore has more performance benefits for objects larger than 10 MB compared to AWS ElastiCache and Anna, and InfiniStore achieves 26.25% and 97.24% tenant-side cost reduction compared to InfiniCache and ElastiCache, respectively.
When Database Meets New Storage Devices: Understanding and Exposing Performance Mismatches via Configurations

Published: May 2023

NVMe SSD hugely boosts the I/O speed, with up to GB/s throughput and microsecond-level latency. Unfortunately, DBMS users can often find their high-performanced storage devices tend to deliver less-than-expected or even worse performance when compared to their traditional peers. While many works focus on proposing new DBMS designs to fully exploit NVMe SSDs, few systematically study the symptoms, root causes and possible detection methods of such performance mismatches on existing databases.
In this paper, we start with an empirical study where we systematically expose and analyze the performance mismatches on six popular databases via controlled configuration tuning. From the study, we find that all six databases can suffer from performance mismatches. Moreover, we conclude that the root causes can be categorized as databases' unawareness of new storage devices characteristics in I/O size, I/O parallelism and I/O sequentiality. We report 17 mismatches to developers and 15 are confirmed.
Additionally, we realize testing all configuration knobs yields low efficiency. Therefore, we propose a fast performance mismatch detection framework and evaluation shows that our framework brings two orders of magnitude speedup than baseline without sacrificing effectiveness.

Published: May 2023

Abstract
Silanes are an alternative to replace pretreatments based on Cr(VI) for electrogalvanized steel (ES). As the interaction between the silane and the metal is important to ensure pretreatment efficiency, surface preparation is a critical step. In this sense, the presence of OH groups on the metal surface is essential. In this paper, the surface preparation of ES and a single/double layer application on the corrosion protection afforded by 3-aminopropyltriethoxy silane was studied. The metal surface was cleaned by polishing, electrochemically (employing anodic or cathodic current) or by chemical oxidation. The electrochemical behavior of the cleaned surfaces was analyzed by cyclic voltammetry and electrochemical impedance spectroscopy (EIS). Afterwards, the hydrolyzed silane was applied in a single or double layer. Coatings were characterized by scanning electron microscopy and energy dispersive X-ray spectroscopy, EIS and by exposure to the humidity chamber. Coatings applied on ES cleaned by electrochemical anodic processes or chemical oxidation provided the best protective performance due to a lower surface of zinc exposed to the high humidity environment. Double layer coatings improved protection due to more homogeneous and higher Si content, sealing defects and increasing the thickness of the one-layer protection, enhancing the barrier protection of the silane.

Abstract
In this work, an efficient and green approach has been presented to prepare carbon quantum dots (CQDs) from watermelon juice through a microfluidic steam-based method, with a view to enabling continuous production at scale, i.e., to save time, costs, or energy as compared to conventional production using an autoclave. The evolution of the product formation through multifarious intermediates generated in different stages of the reaction process was characterized. Computational fluid dynamics simulations reveal the pressure and velocity profiles in the microchannel to exert process control. These determine the quality of the obtained CQDs by influencing the particle size transformations and manifold chemicals along the microchannel axis. The optimal reaction conditions and reaction mechanism for the synthesis of CQDs were investigated. Additionally, the synthesized CQDs demonstrated good fluorescence properties as well as a specific response to

Evaluation on power marketing decision evaluation based on Bayesian network
Authors: Ding Ning , Liu Shifeng , Yao Peng , Wang Fang , Liu Yangcheng 
Published: May 2023

Abstract
The daily production and life of human beings are inseparable from electricity. As the power supplier, electric power enterprises provide power demand for the majority of users. In the new era, electric power enterprises are also facing market-oriented reform. The focus of reform is electric power marketing. The formulation of electric power marketing strategy needs scientific decision-making analysis as guidance. With the increase of power demand, the scale of power grid is also expanding continuously. With the introduction of new energy equipment, the power system is becoming more and more complex, and it is difficult for relevant staff to effectively monitor and analyze the system. Combined with the above situation, this paper combined Bayesian network to build a power marketing decision analysis system, and combined Bayesian algorithm to test the power marketing real-time cost control system. The experimental results showed that the average judgment accuracy was 91.90 %, and the average warning time was 0.39 s. From the above data, it can be seen that this algorithm can play a good optimization effect on the performance of the system. In this paper, the elasticity test of the power system was also carried out from the aspect of wind speed, and the results showed that the maximum elasticity value can reach 0.94. It can be seen that the elasticity effect of the power system is good as a whole under different wind speeds.
Modelling of roller conveyor for the simulation of rubber tire tread extrusion
Authors: Debbaut Benoit 
Published: May 2023

Abstract
The extrusion of large or heavy technical rubber profiles is usually assisted by a conveying device. Such a device can be a conveyor belt or a series of rollers, and its use is necessary mainly for being able to achieve the process. Within the context of numerical simulation of extrusion flows, a conveying device brings additional downstream constraints to the flow governing equations. In the present paper, we propose a simple engineering approach for modelling a roller conveyor used in rubber tire tread extrusion, and we apply it to the extrusion simulation of a flat tire tread profile as typically encountered in the tire manufacturing industry.
The effect of extensional viscosity on the core structure of fiber orientation for injection-molded fiber composites
Authors: Tseng Huan-Chang 
Published: May 2023

Abstract
The famous informed isotropic (IISO) viscosity successfully dominates the broader core structure of fiber orientation distributions for injection-molded long fiber composites, due to the flow-fiber coupling effect of stretching deformation. Recently, the GNF-X (Generalized Newtonian Fluid eXtended) constitutive equation of weighted shear/extensional viscosity has been shown to possess the potential to demonstrate the extension-induced corner vortex in the entry flow of a polymer melt. Using GNF-X, three-dimensional injection-molding flow simulations of a center-gated disk are, therefore, performed for verifying the effect of extensional viscosity on the core structure of fiber orientation, namely, the extension-induced fiber orientation. The equivalent of GNF-X and IISO is demonstrated for predicting fiber orientation distribution, while their primary parameter relationship is particularly found herein. It is significant to visualize dramatic patterns of extensional rate occurring in the center-gated disk simulation.
Understanding the Firm Specific Risk Premium
Authors: Feldman Stan , Feldman Todd 
Published: May 2023

Abstract
We seek to determine whether a firm specific risk premium (FSRP) exists for private firms. We show that private equity investors price firm specific risk as part of establishing the expected rate of return hurdle rate. Our research is based on survey data constructed by the Private Capital Markets Project. We decompose the rate of return into its component parts-market risk premium, size premium, liquidity premium and firm specific risk premium (FSRP). We find that on average PE FSRP varies between zero and six percent. These findings indicate that the cost of capital buildup used in valuing private firms should include a premium for firm specific risk unless facts and circumstances suggest otherwise.
Occurrence and population status of the pond bat (Myotis dasycneme) in Northwest Russia
Authors: Popov Igor , Markovets Mikhail 
Published: May 2023

Abstract
Pond bat Myotis dasycneme is distributed from Belgium to Eastern Siberia, between 44°–50° N and 60° N. The total population of M. dasycneme is probably declining, but supporting data are incomplete. The conservation status of the species is not yet completely assessed. Surveys of hibernacula and foraging sites have been carried out recently in Northwest Russia. Evidence of a recent increase in numbers of wintering bats have been recorded, a northwards expansion is supposed. However, the local pond bat is still under threat as its most significant population is concentrated in only one hibernaculum, which is not well protected.

A gravity model approach to understand the spread of pandemics: Evidence from the COVID-19 outbreak
Authors: Frimpong Albert Opoku , Arhin Kwadwo , Boachie Micheal Kofi , Acheampong Kwame 
Published: May 2023

Abstract
Pandemics disrupt the global economy. Understanding the transmission pattern of pandemics informs policies to prevent or reduce the catastrophic consequences associated with pandemics. In this study, we applied the gravity model of trade to investigate the transmission pattern of the coronavirus disease 2019 (COVID-19) across countries. The results suggest an outbreak in a country is likely to spread faster (slower) from a shrinking (booming) economy to a booming (shrinking) economy.

Published: May 2023

AbstrakKegiatan perikanan tuna dengan penggunaan alat tangkap pole and line dan tonda berisiko menyebabkan kerentanan (risiko ekologi) yang dapat menganggu keberlanjutan stok tuna. Untuk itu dilakukan penelitian menilai kerentanan menjadi parameter risiko ekologi menggunakan pendekatan analisis productivity dan susceptability analysis (PSA) pada jenis ikan tuna sirip kuning (ukuran baby tuna), tongkol, lemadang, dan cakalang. Pengumpulan data biologi dan ekologi dari alat tangkap pole and line dilakukan di Flores dan pancing tonda di Pelabuhanratu. Selanjutnya, analisis laboratorium dilakukan pada Laboratorium Biologi Perikanan, Departemen Manajemen Sumberdaya Perairan, Fakultas Perikanan dan Ilmu Kelautan IPB. Hasil analisis produktivitas dan susceptabilitas alat pole and line untuk ikan baby tuna 1,42 dan ikan tongkol 1,98. Nilai ini menunjukkan tingkat kerentanan dan risiko ekologi pada ikan tongkol tergolong tinggi dan ikan baby tuna masih rendah. Analisis PSA dari alat pancing tonda pada ikan baby tuna diperoleh sebesar 2,34; ikan lemadang sebesar 2,34; dan ikan cakalang 2,18. Nilai ini menunjukkan bahwa kerentanan tinggi dan risiko ekologi pada ketiga jenis ikan tersebut juga tinggi karena penggunaan pancing tonda. Penggunaan alat tangkap pole and line serta pancing tonda pada perikanan tuna menyebabkan tingginya risiko pada ikan tuna sirip kuning (ukuran baby tuna), lemadang, cakalang, dan tongkol. AbstractTuna fishery activities using pole and line fishing gear and tonda have the risk of causing vulnerability (ecological risk) which can disrupt the sustainability of tuna stocks. For this reason, a study was conducted to assess vulnerability which is a parameter of ecological risk using the productivity and susceptibility analysis (PSA) approach to the fish’s species are albacares (baby tuna), mackerel, lemadang, and skipjack. Biological and ecological data collection from pole and line fishing gear was carried out in Flores and trolling and tonda in Pelabuhanratu. Furthermore, laboratory analysis was carried out at the fisheries biology laboratory, Department of Aquatic Resources Management, Faculty of Fisheries and Marine Sciences IPB. The results of productivity and susceptibility analysis of the pole and line for baby tuna and Euthynnus are 1.42 and 1.98. This value shows the level of vulnerability where the ecological risk of tuna is high and baby tuna also low. The PSA analysis of the tonda for baby tuna was 2.34; lemadang was 2.34; and skipjack was 2.18. This value indicates that the high vulnerability and ecological risk of the three species of fish are also high due to the use of tonda. The use of pole and line fishing gear and tonda lines in tuna fisheries causes a high risk for albacares (baby tuna), mackerel, lemadang, and skipjack.
Simple Interventions for Pediatric Residents’ Moral Distress: A Randomized, Controlled Experiment
Authors: Kesewa Layman Awo Akosua , Press Callahan Katharine , Nathanson Pamela , Lechtenberg Lara , Hill Douglas , Feudtner Chris 
Published: May 2023

BACKGROUND AND OBJECTIVESPediatric residents are at high risk for moral distress, knowing the moral or ethically right thing to do but feeling unable to do it, which is associated with poor patient care and burnout. Researchers have proposed numerous interventions to reduce distress, but few (if any) have been supported by experimental evidence. In this study, we used an experimental method to provide proof-of-concept evidence regarding the effect of various simple supports on pediatric residents’ reported degree of moral distress.METHODSWe conducted a study of pediatric residents using a split sample experimental design. The questionnaire contained 6 clinical vignettes describing scenarios expected to cause moral distress. For each case, participants were randomly assigned to see 1 of 2 versions that varied only regarding whether they included a supportive statement. After reading each of the 6 cases, participants reported their level of associated moral distress.RESULTSTwo hundred and twenty respondents from 5 residency programs completed the experiment. Cases were perceived to represent common scenarios that cause distress for pediatric residents. The addition of a supportive statement reduced moral distress in 4 of the 6 cases.CONCLUSIONSIn this proof-of-concept study, simple yet effective interventions provided support by offering the resident empathy and shared perspective or responsibility. Interventions that were purely informational were not effective in reducing moral distress.
Relações entre a motivação escolar e o hábito de leitura entre alunos de ensino médio
Authors: Vieira Costa Rafaela , Manhães Sales Felippe Jonis 
Published: May 2023

Reconhecendo a motivação escolar como um fator importante no âmbito educacional, este artigo tem o objetivo de analisar a relação entre esse fenômeno e a leitura no ensino médio. Como estratégia de coleta de dados da pesquisa, foram aplicados uma escala de avaliação da motivação escolar para aprender, desenvolvida por Neves e Boruchovitch (2007), e um questionário sobre leitura, que foi desenvolvido pelos pesquisadores. Participaram da pesquisa duas turmas de terceiro ano do ensino médio de um colégio estadual localizado no município de Campos dos Goytacazes - RJ. Os dados quantitativos coletados foram tabulados e organizados em quadros para facilitar a exposição. Os resultados da escala e do questionário foram relacionados e analisados a fim de verificar a relação entre a motivação escolar para a aprendizagem e os hábitos de leitura dos alunos no ensino médio. Todo esse caminho confirmou, devido compatibilidade entre os resultados da escala e do questionário aplicados, a veracidade da hipótese de que alunos motivados intrinsecamente pela aprendizagem tendem a ter melhores hábitos de leitura.
Tuo Dolphins
Authors: Scott Rolf Erik , Crawford Peter Ian 
Published: May 2023

Tuo Dolphins takes place in both Aarhus, Denmark and in the Reef islands, the Solomon Islands. Moffat Bonunga, visits the Danish anthropologists Jens Pinholt and Peter I. Crawford in Aarhus to help them with their work on the film project. This included talking about a special event when dolphins ran ashore at Tuo village. The people of Tuo have a mythical relationship with dolphins, covered by a traditional so-called kastom story, the incident confirming the fascinating relationship between the dolphins landing on the beach and the kinship relationships. The phenomenon had allegedly been triggered when a member of a specific family line, Pelewe, passed away a few weeks before. The villagers decided to re-enact part of their Dolphin story to capture it on film, thereby using the film, and its crew, to both present and confirm the truthfulness of the legend and myth.
