A description of Validation Processes and Techniques for Ocean Forecasting
Authors: Sotillo Marcos G. , Drevillon Marie , Hernandez Fabrice
Published: September 2024

Abstract. Operational forecasting systems architecture requires clear identification of best practices for assessing the quality of ocean products: it plays a key role not only for the qualification of predictions skill, but also for advancing in the scientific understanding of the ocean dynamics from global to coastal scales. The Authors discusses on the role of observing network for performing validation of ocean model outputs, identifying current gaps (i.e., different capacity in assessing physical essential ocean variables versus biogeochemical ones), but also emphasizing the need of new metrics (tailored for end-users comprehension and usages). An analysis on the level of maturity of validation processes from global to regional systems is provided. A rich variety of approaches exist, and the most we move towards the coast the higher is the complexity in calculating such metrics, due to increased resolution but also somehow limited by the lack of coastal observatories worldwide. It is provided as example how the Copernicus Marine Service currently organizes the product quality information from producers (with dedicated scientific documentation, properly planned and designed) to end-users (with publication of targeted estimated accuracy numbers for its whole product catalogue).

Published: September 2024

Las úlceras crónicas impactan significativamente en la calidad de vida del paciente y generan elevados costos para el sistema de salud. Un enfoque terapéutico integral, considerando el diagnóstico y las características de la herida, es esencial para cada fase de cicatrización. Durante la epitelización se recomienda el uso de técnicas con injertos para acelerar la reparación, mejorar la calidad del tejido cicatrizal y abordar el dolor. La técnica de autoinjerto por punch de unidades foliculares, obtenidas del cuero cabelludo, se presenta como una estrategia aceptada para la reparación de heridas crónicas. Se ilustra el caso de un paciente de 79 años con múltiples comorbilidades y con una úlcera arterial de importante dimensión donde, luego de controlar la patología de base y lograr un lecho óptimo, el autoinjerto con unidades foliculares, derivó en la completa cicatrización al cabo de 4 meses.

Published: September 2024

O objetivo deste artigo consiste em compreender modos de inserção do setor privado no Ensino Médio público no estado de Mato Grosso, a partir da adoção do Sistema Estruturado de Ensino. Apresenta-se o contexto da década de 1990 como incentivador das parcerias com o setor privado, diante da sua suposta eficiência de gestão. A compra de material apostilado, pelo poder público, articula-se ao discurso de superioridade metodológica das escolas privadas, desconsiderando as especificidades da administração pública. Foi possível identificar, a partir do levantamento bibliográfico e documental, na proposta mato-grossense, o material apostilado na dinâmica do Plano EducAção 10 anos, que visa posicionar a rede entre as cinco redes públicas mais bem avaliadas no país até 2032, aliado à Plataforma Escolas Conectadas e à plataforma digital Plurall, que contém a versão digital dos materiais, com atividades complementares. A privatização da educação é considerada um projeto de longo prazo, que vem se concretizando.
A utopia de Björk
Authors: Gonçalves Magossi Priscila , Machado Garcia Jaimeson
Published: September 2024

O estudo propõe uma análise aprofundada das letras das músicas, da sonoridade e da capa do álbum Utopia de Björk, lançado em novembro de 2017. A argumentação busca compreender como a artista islandesa utiliza esses elementos artísticos no intuito de transmitir uma mensagem sobre a busca pela utopia, isto é, o estado idealizado do mundo em harmonia completa.  Para tanto, o artigo apoia-se na reflexão teórica proposta pelo compilado de autores Edgar Morin, Ernest Cassirer, Joseph Campbell, Junito Brandão, Mircea Eliade e Vilém Flusser sobre a relação inextricável entre o homem primordial e a natureza, expandindo-se para a compreensão da estrutura (simbólica) do pensamento mítico. Em seguida, avança-se na argumentação ao considerar o papel da música na contemporaneidade. Assim, o estudo destaca a posição de Björk na tradição de incorporar temas naturais em sua produção musical, e propõe uma análise cuidadosa para desvendar o modo pelo qual esses elementos artísticos contribuem para a expressão da mensagem utópica ecológica. Seu álbum Utopia (2017) é explorado como reflexo dessas ideias, apresentando uma visão de mundo idealizado — portanto, utópico — no qual a convivência entre humanos, natureza e tecnologia é possível. Por fim, o estudo analisa as composições musicais, os arranjos e a capa do álbum no intuito de desvendar os significados e interpretações subjacentes à obra. Destaca-se a potência da música de provocar reflexões sobre valores e ideais, bem como encorajar o estímulo da imaginação criativa em meio às demandas da vida cotidiana.

Os protegidos de Ceres: produtores, moageiros e política cerealífera nos Açores (1923-1932)
Authors: Pires Leonardo
Published: September 2024

This article departs from the economic and political context of the transition from the 1920s to the 1930s to study the evolution of the cereal policy in Azores. In this dynamic change process, agriculture, in general, and cereal farming, in particular, have been heavily targeted by public policies and governmental decisions. Our main purposes are the analysis of the organization, relations and implications of the activities of the agents involved in the commodity chain of wheat. It was concluded that the forms of public mobilization and pressure of the economic elites, in this case, the millers and agricultural landowners, on the political instances were not far from what occurred in the continental context, although the state has become the ultimate regulatory element.
The Symbolic Capitals of Artists and the Legitimacy of Artificial Intelligence Arts: Focusing on Damien Hirst’s 「Beautiful Paintings」
Authors:   Korean Association of Arts Management, Kang Qiaozheng , Lee Jinwoo
Published: September 2024

This study aims to understand the linkage between an artist's symbolic capital (reputation) and the legitimization of that artist's AI art. Based on Bourdieu's concept of cultural capital, to do so, we theoretically reviewed symbolic capital. Then, the qualitative study was conducted by considering contemporary artist Damien Hirst's AI art project “Beautiful Paintings” as a case. Secondary data such as Hirst's career records, research papers, articles, reports, websites, and the artist's social media were collected and analyzed. The results indicate that the symbolic capital of Hirst has accumulated in the art world and the art market influences the acceptance of his AI art in the market. Hirst, to transfer his symbolic capital to AI art, highlights his role in producing the AI art via social media and connects his established image with the debate surrounding AI art. Furthermore, Hirst intends to generate a visual similarity between his recognized artistic style (Spin Painting) in the art world and Beautiful Paintings, as well as emphasizing the 'randomness' inherent in both AI art and Spin Painting. By doing so, the success of AI Art, supported by the symbolic capital of the renowned artist, implies that the hierarchical structure built within the art world for the legitimization of artworks is partially maintained even in art applying new technologies.

Published: September 2024

Objective: Central/Abdominal obesity is an important health problem that is growing all over the world. Abdominal obesity has been recognized as a main risk factor for cardiovascular and metabolic events. There are various measurements ranging from anthropometric indices to imaging methods for the determination of abdominal obesity. However, anthropometric studies involving older adults are scarce in the literature. The purpose of this study is to compare the current anthropometric measures used to evaluate abdominal obesity in older adults.
Materials and Methods: In total, 104 outpatients aged 65 years or older were enrolled in this cross-sectional study. For any reason, patients with an indication for Dual-energy-X-ray Absorptiometry (DXA) were included. Anthropometric and haemodynamic measurements were taken. DXA was used to measure body composition, especially fat ratio.
Results: The mean age of patients was 74.66.9. The ratio of adiposity determined by DXA, which was used as reference/gold standard method, was in the range of 3.8-52.5%. Mean value of adiposity was 31.510.9%. When gender and anthropometric indicators were compared, body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and body adiposity index (BAI) were significant (p0.05). The best three anthropometric indicators that estimating the fat ratio in participants were; BMI (r=0.718, p

Authors: Djimeli Paulin Marvel , Fendji Marie Danielle , Ekengoue Clautaire Mwebi , Djiyo Denis , Youagam Richard Vivien
Published: September 2024

The weather conditions of Nsanke village starting from April to October emphasis the need for judicious utilization of warm water. We designed, constructed and tested a Solar Water Heater based on Thermosyphon principle in Nsanke village using locally available materials. Solar energy is received by two flat-plate collectors of 1.68 m2 each, consisting of absorber plate carrying copper tubes and placed in an insulated casing with a transparent glass cover of thickness 4 mm. The collectors are connected in series and are assumed to operate on the same efficiency. The resultant collector is connected to a storage tank, which is an association of two barrel nested overall and separated with an insulator. The radiation emitted by the absorber plates cannot escape through the glass, thus increasing its temperature. The system’s performance evaluation has shown that it can heat water from 23°C to at least 51°C on sunny days. The water heated flows into a storage tank through Thermosyphon principle. The Solar Water Heating System uses the Thermosyphon principle and can therefore be called Thermosyphon Solar Water Heater (TSWH) for simplicity. This system finds useful application in serving as a renewable energy resource in Nsanke village and neighboring villages.

VIMS RESEARCH TO TEST THE HYPOTHESIS OF A POSSIBLE SHIFT IN THE 235U/238U ISOTOPE RATIO IN NATURE AND THE USE OF THIS PHENOMENON IN THE SEARCH FOR ANCIENT RICH URANIUM DEPOSITS
Authors: Бахур А.Е. , Печенкин И.Г.
Published: September 2024

На примере исследований сотрудниками ВИМСа в 1970–1972 гг. месторождения урана Северинское в северной части Кировоградского урановорудного района удалось экспериментально подтвердить возможность смещения отношения 235U/238U в урановых рудах. Оно изменялось как в сторону «выгорания» 235U, так и его накопления, в зависимости от условий локализации оруденения и происходящих в нем ядерных преобразований. Информация Французского Комиссариата атомной энергетики (CEA), об открытии естественной самоподдерживающейся реакции ядерного деления от 25 сентября 1972 г., лишь подтвердила экспериментальные результаты и выводы ученых ВИМСа, полученные ранее.

It was experimentally confirm the possibility of 235U/238U ratio shift in uranium ores, using the example of research by VIMS employees in 1970–1972 of the Severinskoye uranium deposit in the northern part of the Kirovograd uranium ore district. It varied towards both the «burnout» of 235U and its accumulation, depending on the conditions of mineralization localization and the nuclear transformations taking place in it. Information from the French Commissariat of Atomic Energy (CEA), on the discovery of a natural self-sustaining nuclear fission reaction on September 25, 1972, only confirmed the experimental results and conclusions of the VIMS scientists obtained earlier.

Transitioning to Alternative Fuels: A Study on the Feasibility of Synthetic Fuels in Saudi Arabia’s Road Transport Sector
Authors: Mahrous Elaf N. , Yousufuddin Syed , Saleem Muhammad
Published: September 2024

Researchers are exploring alternative fuels to transition away from conventional fuels, driven by the need to reduce carbon emissions and dependence on fossil fuels. The transportation sector is a significant consumer of fuels, making it a crucial area for alternative fuel adoption. This study is an expansion on earlier works by recognizing the potential for synfuels derived from fossil fuels to compete with fuels derived from renewable sources. Study illustrating possible transition scenarios in the road transport sector to replace gasoline and diesel in fossil fuel-dependent economies, including Saudi Arabia. The study highlights the potential of alternative fuels like ethanol and hydrogen to meet demand due to of technology developments that increase efficiency and reduce the costs. The findings demonstrate that by 2050, synthetic fuel production will significantly lower the crude oil consumption and CO2 emissions. This study, a first for the region, assesses the implementation of synthetic fuels produced from fossil fuels. Study shows that significant modification in policies and their execution is required, and alternative fuels can be cost-competitive with conventional fuels if Saudi Arabia’s strict CO2 reduction targets are met. The study provides a preliminary assessment of the system implementation and underscores the need for strict regulations to drive the transition to alternative fuels.
STEAM INDUCED SHOCKWAVE INTERACTION WITH A SUBMERGED PLATE CONFIGURED AT A RANGE OF INCLINATIONS FROM VERTICAL
Authors: Almalowi Saeed , Khan Afrasyab
Published: September 2024

Interaction of shock wave and the shear induced vortex across the steam-water layer has been vital in several transportation and chemical industrial processes. Experiments were conducted using a facility including a rectangular chamber, which housed a shock tube in it. Steam was injected into the tube to induce shock wave by bursting the Aluminum diaphragm disk and the shock wave surrounding by the steam-water shear layer induced vortex, exited the shock tube and struck the rectangular steel plate. PIV setup along with the pressure and acoustic emissions sensors were used to characterize the propagation and impingement of the shock wave on the plate as well as the behavior of the reflected shock wave and the vortex ring. In case of a vertical rectangular steel sheet stationed in front of the exit of the shock tube, the central part of the shock wave was found to interact with the central part of the vortex structure and the external part of the shock wave came into contact with the outer part of the vortex structure. Whereas in case of inclined sheet, the shockwave reflected from the sheet, came into collision with the rebound shockwave as well as with the lower portion of the vortex ring largely. However, with the further variation in the angle of inclination (i.e. 30o and larger) fromvertical axis, no further appreciable change was observed in the flow profile except the vortex ring interacted earlier with the rebounded shockwave in the lower region within the neighborhood of the plate than the interaction of the vortex ring with the rebounded shock wave in the upper region of the inclined plate. The pressure and acoustic emission measurements were symmetric with the vertical plate, however, the pressure data was asymmetric when the plate was inclined from vertical. When the angle of inclination changes to 30 degrees from the vertical, the flow becomes more asymmetric as the shockwave and the consequent vortices impinged on the surface of the plate much earlier than the 15 degrees’ inclination case.
Revisione delle cipree (Mollusca, Cypraeoidea) mesozoiche italiane
Authors: Capasso Luigi
Published: September 2024

The author presents the revision of the 17 specimens of Mesozoic cypraeids found in Italy, following the direct re-examination of the specimens, three of which are currently lost. The review led to the identification of only six formally valid species, belonging to four genera: (i) Palaeocypraea tithonica and (ii) Bernaya gemmellaroi, from the Tithonian of Termini Imerese and the Island of Capri; (iii), Bernaya apenninica (not Cypraea retusa, preoccupied name) from the Cenomanian of the Ocre Mountains; (iv) Cypraea pustulifera, from the Cenomanian of the Ocre Mountains; (v) Bernaya molisana sp. nov., from the Turonian-Senonian of the Matese. Furthermore, direct examination of the types allowed me to definitively establish that (vi) Bernaya (Protocypraea) striata, also from the Cenomanian of the Ocre Mountains, belongs to the genus Ovula. From a paleoecological and evolutionary point of view, it is confirmed that the first fossil forms of cowries date back to the Jurassic and began to diversify in the Cretaceous in the Mesozoic reef environment characterized by high energy, thanks precisely to the tiny dimensions, as well as the thickness and shape, almost hemispheroidal, very slightly elongated in the longitudinal direction, of their convoluted niche. Finally, we underline the importance of the two forms from the Tithonian age, which represent the oldest cowrie taxa known today, Palaeocypraea tithonica and Bernaya gemmellaroi.

Authors: Forli Maurizio , Bogi Cesare , Cresti Massimo , Guerrini Andrea , Dominici Stefano
Published: September 2024

The revision of fossil specimens mainly collected in the sixties of the last century and today hosted at the Museo di Storia Naturale of Pisa allowed to update the taxonomy of Lower Tortonian bivalves and some gastropods of the Ponsano Sandstone, cropping out in southern Tuscany in the Pisa and Siena provinces. The stratigraphy of the original successions was reconstructed and quantitative data were estimated by counting museum specimens and by transforming literature semiquantitative data into quantitative ones. The paleoecology of three successive main assemblages has been defined by measuring the relative abundance of bivalves and the transgressive-regressive trend of the succession in the type area (previously known from sedimentary and micropaleontological data) has been confirmed for the first time based on the macrofauna.
Blockchain-Based Verifiable Computation: A Review
Authors: Zara Maham , Wang Shuzhen , Ul Moin Hasan
Published: September 2024

Verifiable computation has been studied as a way to verify the outcomes of an outsourced computation. It is usually seen from the view of a user who wishes to outsource computation to a centralized third party but wants to ensure that the party provides correct results. With the said scheme, the verifier requests the prover to perform the computational task and then verifies the outcome by checking the output and the proof obtained from the prover. However, there are several security challenges within a centralized third party to execute verification tasks. Recently, the advancement in blockchain technology has offered an opportunity to solve these security challenges. Blockchain is a distributed ledger and decentralized technology that eliminates the need for third-party verification. In recent years, the emergence of innovative applications of verifiable computing techniques within blockchain technology has been witnessed. These applications focus on ensuring secure key management, enhancing smart contracts, and fortifying sybil-resistance. The use of blockchain in the realm of verifiable computing has drawn the attention of many researchers. However, our research into relevant papers revealed a notable lack of comprehensive surveys on blockchain-based verifiable computing in the literature. To overcome this gap, we conducted a comprehensive survey on blockchain-based verifiable computation. First, we address fundamental concepts related to blockchain-based verifiable computation. Afterwards, we offer a series of criteria to evaluate existing blockchain-based verifiable computation techniques. Finally, based on our comprehensive review and evaluation metrics, we explore various open challenges and potential research prospects. These include zero-knowledge proofs (ZKP) integration, addressing privacy preservation, scalability, and traceability. Future research should focus on robust privacy-preserving methods, using ZKP for enhanced security, off-chain computations for scalability, and decentralized file systems like Interplanetary File System (IPFS) to improve traceability.

Published: September 2024

Changes in climate together with rapid urbanization are putting immense pressure on the existing agriculture and natural resources of South Asia. The agriculture productivity and livelihoods of a large number of communities have become highly vulnerable to inadequate supplies of water, especially in the rainfed regions. In the present study, spatio-temporal changes in rainfall patterns have been analyzed in different agro-ecologies of Pakistan during 1960-2019 period for sustainable agriculture and natural resource management in the country. Major agro-ecologies identified in the country were western dry mountains over 19.1% area, western dry plateau over 14.4% area, sandy desert over 14% area and northern irrigated plain over 11.3% area of the country. An increase of 30.6% in annual rainfall was observed in the rainfed plateau zone, 14.2% in the piedmont plain and 5.9% in the western dry mountain zone during the 1960-2019 period. In contrast, the rainfall exhibited a 3.2% decrease in the western dry plateau and 6.2% in the coastal zone which is critical for the subsistence agriculture in these arid ecologies. The excess rainwater may be conserved through developing storage/farm ponds and reservoirs for subsequent use during dry periods and recharging groundwater to build resilience against drought/flood conditions. The rainwater harvesting (RWH) has the potential to sustain agricultural productivity and fulfil the growing needs of the population in the arid ecologies of the country. Regular monitoring of the water resources is essential in the context of the rapidly changing environment and growing needs of the population in this arid region in future.
SİYASAL BİR TASARI OLARAK PLATON’DA İDEA
Authors: Dore Fatma
Published: September 2024

Atina demokrasisinin Sokrates'i idam etme kararı, öğrencisi Platon üzerinde derin bir etki yaratmıştır. Bu, Platon için korkunç bir adaletsizlikti, çünkü Sokrates onun gözünde hiçbir şekilde suçlu değil, bilakis evrensel ahlaki öğretiler yoluyla toplumunu iyileştirmeye çalışan biriydi. Bu nedenle Platon, Atina demokrasisine tamamen yabancılaşmıştı ve bu duygusu, kelimenin tam anlamıyla, anavatanını terk etmek ve o zamanlar uygar dünya olarak görülen yerlere, tabakalaşmış yapıları dolayısıyla demokratik olmayan toplumların gerçekte nasıl işlediğini öğrenmek ve bunların kendi şehir devletinden üstün olup olmadığını görmek için yaptığı yoğun seyahatler şeklinde tezahür etti. Netice itibariyle öyle olduklarına kanaat getiren Platon, Atina'ya döndüğünde, onlarda gözlemlediği gibi sınıflara ayrılmış, ancak kendisine özgü şekliyle yönetici sınıfta krallar ya da rahiplerin değil de filozof koruyucuların olduğu ideal bir devlet için bir plan oluşturmak amacıyla bu örneklerden yararlandı. Platon, bu devleti ideal bir devlet haline getirerek, onu dünyevi meselelerin üstüne yerleştirmeye ve eleştiriden muaf tutmaya, böylelikle zaman ve mekan bakımdan evrensel olacak bir siyasi formül oluşturmaya çalışmıştır.

Published: September 2024

In light of environmental concerns about cement manufacture, limestone and thermally activated kaolinitic clays are being explored as supplementary cementitious materials with the potential to reduce CO2 emissions and energy usage. The use of calcined clay and limestone for clinker replacement to create a tertiary blend called limestone calcined clay cement (LC3) is one of the most promising emerging technologies for meeting environmental requirements. This paper reports on the evaluation of the fresh-state and hardened properties of cementitious pastes and self-compacting concretes (SCC) prepared using the concrete equivalent mortar method made with LC3 systems containing 30%, 35%, and 40% metakaolin (LC-30MK, LC-35MK, and LC-40MK) in comparison with ordinary Portland cement (OPC). Paste and concrete equivalent mortar specimens were prepared to investigate water demand, setting time, and workability (mini-slump flow test). Also, the compressive strength and drying shrinkage after 7 and 28 days, as well as thermal conductivity after one year of curing, were examined. The obtained results showed that the incorporation of metakaolin resulted in increased water demand to reach normal consistency. The setting time of LC3 mixtures also increased, while the same workability behavior was observed for all mixtures. LC-30MK can provide compressive strength that is comparable to OPC, especially after the first few days of curing. However, the compressive strengths of LC-35MK and LC-40MK are lower than those of OPC. Nevertheless, they demonstrate noteworthy strength characteristics. All LC3 mixtures exhibited relatively low drying shrinkage and reduced thermal conductivity compared to the OPC mixture.

The Main Controlling Factors of the Development and Extinction of ' Carbonate Factory '
Authors: Li Linwei , Shu Ting
Published: September 2024

Building upon the profound foundation of previous research on carbonate factories, this paper systematically organizes the classification system of carbonate factories and delves into the primary controlling factors of their demise, thereby providing a more precise portrayal of the diverse facets and intricate evolution of carbonate factories throughout geological history. Based on carbonate rock types, sedimentary environment characteristics, the dominant agents in the construction process, deposition and precipitation patterns, as well as oceanographic conditions, the carbonate factories are categorized into five major groups, each of which is comprehensively described. Furthermore, this paper summarizes six key controlling factors: fluctuations in nutrient levels, anoxic events, tectonic activities, massive inputs of terrestrial materials, mass extinctions of organisms, and significant changes in sea level. It delves into how these factors, acting either independently or synergistically, lead to the demise of carbonate factories, elaborating on the corresponding processes and mechanisms in detail.

Authors: Rioni Yunita Sari
Published: September 2024

The purpose of this study is to prove and analyze the factors that influence the choice of inventory valuation methods in industrial companies on the Indonesia Stock Exchange. In this study, an associative quantitative research approach was used, namely research aimed at examining the effect or relationship between two or more variables. The data analysis technique used logistic regression analysis method. Logistic regression is an analytical tool used to measure the influence of the independent variable on the dependent variable in the form of a dummy variable. The results of data analysis and discussion prove that company size (SIZE) has an effect on the selection of inventory valuation methods for industrial companies on the IDX for the 2015-2017 period. Inventory intensity affects the selection of inventory valuation methods for industrial companies on the IDX for the 2015-2017 period. Simultaneously company size (SIZE), and Inventory Intensity affect the selection of inventory valuation methods for industrial companies on the IDX for the 2015-2017 period. The greater the size of the company, the more access it can be for managers to establish a constant (unchanging) inventory valuation method. Companies that are larger in size are thought to have a greater tendency to choose the correct method. Based on the political cost hypothesis in positive accounting theory, it is stated that large companies tend to manage their inventory well. Changes in the inventory valuation method from the average method to FIFO will cause the company's profits to be higher and it is expected that the company's shares can be sold at a price that is favorable to the company. The results of this study indicate that the net profit margin has an effect on the choice of inventory valuation method because the companies used in this study are companies that earn profits.
