Authors: Kotov V. M. , Kotov S. V.
Published: November 2024

Nuclear reactors based on fission of heavy nuclei were created a decade after the discovery of uranium fission by neutrons. Attempts to create reactors based on synthesis of light nuclei have been continuing for more than seven decades. The main direction of their implementation repeats natural technologies - implementation of reactions under the influence of high (stellar) temperatures. This direction has faced a lot of problems, and in the modern sense requires huge investments for its implementation. There are developments based on the use of accelerator technology. In this paper, there is an assessment of feasibility to create synthesis reactors using colliding ion beams of the D-D, D-T, D-3He reactions. The technical solutions applicable for their implementation are shown, advantages of such reactors over thermonuclear reactors, possibility of producing fuel for them and the problems that arise.
USE OF ROTARY-PETAL ENGINES IN AVIATION
Authors: Kotov V. M.
Published: November 2024

Transition of aviation to turbojet engines, which started actively in the forties of the 20th century, enabled significantly increasing flight speeds due to eliminating problems associated with peculiarities of propeller operation at high speeds. For many years, flights with turbojet engines at relatively low speeds (up to 500–700 km/h) were less cost-effective than on piston propeller airplanes. Development of aviation turbine technology has largely eliminated disadvantages of cost effectiveness. However, engines themselves have become more complicated, more expensive, but in recent years, the rate of increase in efficiency has been slow. The total fuel consumption increases due to the increase in traffic volume. Many problems in this area can be solved by using cost-efficient rotary-petal engines of internal combustion. Possible technical solutions for development of this area are shown.

Authors: Emelyanenko E. , Petkevich M.
Published: November 2024

The reliability of obtaining qualitative and quantitative information in positron emission tomography depends on the level of depth of quality control of the diagnostic image. Given the active application of the procedure for planning radiation therapy using positron emission tomography combined with computed tomography, an urgent task is to assess the accuracy of combining the modalities of diagnostic images. In this work, we estimated the discrepancy between the volumes of the radiopharmaceutical accumulation foci (when combining PET and CT modalities of images) using a computer-based radiation therapy planning system. The influence of additional factors that may affect the correct combination of images is considered: time-of-flight technology, the number of subsets (the number of free projections used during reconstruction). The functional dependences of the discrepancy between the volumes of modalities (PET and CT images) on the volume of potential foci of accumulation (which are used as hot spheres) of the radiopharmaceutical preparation are obtained. The discrepancy between the diameters of the spheres measured on a CT image with the real diameters of the spheres is estimated.

Published: November 2024

As a result of the processing of gravimetric data from the GOSE and GRACE satellites, a global gravimetric map of the vertical gradient of gravity and a gravimetric map for the Northern Tien Shan region were obtained. In constructing the vertical gradient of gravity at the height of the satellite, the data of the gravitational gradient from the website of the European Space Agency were used. The provided gravitational gradient data formats are defined by two main subsets of files: a subset of gravitational gradients in the gradiometer reference system (GRF) and a subset of gradients in the reference system that rotates relatively to the ground reference system (TRF), in particular, in a spherical locally north-oriented reference system (LNOF). The gradients of the gravitational gradient 225 km and 255 km above the ellipsoid were calculated using GRACE-GOCE gravity gradients along the orbit as input. Satellite gravity data are used to analyze seismically active zones. As a result of studies, it was found that the epicenters of the centers of large earthquakes correlate with the location of the zones of sharp changes in the vertical gradient of gravity.

Authors: Wolbers Heather , Dowling Christopher
Published: November 2024

This study examines factors associated with dating app facilitated sexual violence (DAFSV) among a large, nationally representative sample of dating app or website users (n=9,987). Through the lens of routine activity theory, we examined the way in which respondents used dating platforms and how this was associated with experiences of DAFSV. Prolific dating platform users and those who share more information, who chat with people on different platforms or who paid for an online dating service were more likely to report experiencing DAFSV. Risk factors for DAFSV extending from the online sphere into the physical world were also explored. Findings give much needed context for experiences of DAFSV and provide direction for responses aimed at protecting individuals from harm facilitated by online dating platforms.
Húsipari vállalatok jövedelmezőségének vizsgálata a polikrízis tükrében

Published: November 2024

A 2020-as évtized elejére jellemző a polikrízissel leírható jelenség, amely a már korábban elterjedt sertéspestis és madárinfluenza, valamint a Covid-19 miatt bevezetett kereskedelmi korlátozások, határlezárások, a szélsőségesebbé váló időjárási anomáliák, aszályok, illetve az ukrajnai háború okozta takarmány- és energiaárnövekedés egyidejű jelenlétében öltött testet. A polikrízis hatásaként leginkább a mezőgazdaságra épülő magyar húsfeldolgozás, -tartósítás, húskészítménygyártási alágazatra koncentrálódott. A tanulmány célja az ezen alágazatban működő három vállalat: a Tranzit-Food Kft., Kaiser Food Kft. és a Sága Foods Zrt. eredményességére gyakorolt tényezők hatásainak elkülönült vizsgálata a polikrízis időszakában és azt megelőzően. A kutatás során megvizsgáltuk, hogy a madárinfluenza és sertéspestis okozta alapanyaghiány a Covidnál nagyobb hatást gyakorolt-e az alágazatra, valamint, hogy ez utóbbiak és az anyagköltségek emelkedése az eltérő értékesítési struktúrával rendelkező vállalatok eredményére eltérő hatást fejtettek-e ki. A három cég teljesítménye között a 2020-as választóévtől függően jelentősebb különbségek mutatkoztak. A sajáttőke-arányos jövedelmezőséget eltérő mértékben befolyásolták az időben késleltetve meghozott korlátozások az exportőrök esetében. Miközben ők nagyobb mértékben tudták kivédeni az importból fakadó árfolyamkockázatot a leginkább a hazai piacokat preferáló versenytársukkal szemben, addig a hazai piacokat előnyben részesítő vállalat a – polikrízis egy újabb jeleként megjelenő – növekvő hazai inflációt kihasználva volt képes magasabb kamat- és árbevétel elérésére.

Published: November 2024

Centralized Health Intelligence (CHI) represents an ecosystem where data, technology, and expertise converge to elevate the standards of healthcare services. In this case study, we explore the pivotal role of CHI in reshaping the healthcare paradigm at the Primary Health Care Corporation (PHCC) in Qatar. Adopting clinical information systems led to a wealth of data, necessitating the transformation of the conventional health information management team into the Business and Health Intelligence (BHI) Department. The establishment of a centralized enterprise data warehouse (EDW) and the use of business intelligence tools by the BHI Department further contributed to improved data governance. A meticulous Centralized Health Intelligence Framework was devised to ensure the effective use of PHCC's data assets. This framework encompasses policies and procedures related to data stewardship, information needs assessment, data classification, data privacy, and data literacy requirements. Through this study, we demonstrate how PHCC has harnessed CHI to redefine healthcare delivery by providing relevant stakeholders with easy access to advanced data analytics and data-driven decision-making tools. Implementing CHI infrastructure presents many challenges, including financial, technical, and organizational hurdles. Despite these challenges, CHI significantly benefits relevant stakeholders by providing enhanced access to health data, fostering active engagement. However, addressing data comprehension, security, and privacy concerns remains critical.

Authors: Leal José H , Hulse Carly , D'Agostino Claire , Fogelson Susan
Published: November 2024

This study reports the first record of imposex in Triplofusus giganteus, a top predator in shallow water marine habitats. Imposex, an irreversible disorder in female caenogastropod snails caused by exposure to biocidal organotin compounds identified in vessel antifouling paints, was observed in three of four snails collected from Alligator Harbor, Florida, with affected females developing a non-functional male reproductive organ, the pseudopenis. The presence of imposex in this species is of particular concern for its long-term conservation, given its slow maturation, limited reproductive output, and the potential impact of environmental contamination.

Published: November 2024

As transformações constitucionais no constitucionalismo latino-americano estão marcadas pela coexistência de estruturas hiperpresidencialistas com o surgimento de instituições responsáveis pelo desenvolvimento de melhores práticas de governança democrática em um contexto de crise na teoria da separação dos poderes. O desenho institucional da Argentina no combate à corrupção fornece um caso paradigmático no qual a concentração de poder no Executivo se choca com a atuação fiscalizadora da Oficina Anticorrupção, razão pela qual realizou-se o estudo de caso dessa interação institucional. Para tal análise, a pesquisa foi desenvolvida em fases distintas. Na primeira etapa, a abordagem utilizada foi a crítica-analítica e estrutural, explorando o campo teórico-abstrato a partir do método comparativo. Na segunda etapa, realizou-se a investigação empírica da Oficina Anticorrupção, avaliando o desempenho da instituição na dinâmica do sistema político argentino. Por fim, a partir das avaliações obtidas, indicou-se caminhos institucionais para reestruturar a Oficina Anticorrupção de modo a impactar a sua atuação e elevá-la ao patamar de instituição híbrida de acordo com as premissas propostas. Dentre os resultados alcançados, destaca-se que a Oficina Anticorrupção, por sua estrutura, não se encontra alinhada aos pressupostos de autonomia, independência, transparência e eficácia elementares às instituições híbridas, sendo necessárias reformas.
A desconstrução do controle jurisdicional de políticas públicas sobre o exercício de direitos sociais: um estudo sobre os limites dos entornos político e jurídico e a relevância do modelo liberal de direito
Authors: Agustinho Eduardo Oliveira , Alcalde do Nascimento Victor Hugo
Published: November 2024

O emprego de termos técnicos no Direito omite os argumentos, filosofias e fundamentos responsáveis pela sua construção. Aceitam-nos, quer por sua índole técnica, quer por habitualidade profissional. Desconstrui-los, no entanto, revelaria justificativas omitidas e opções negligenciadas. No Direito Constitucional, excluem-se políticas públicas do âmbito jurisdicional por sua índole política e diminuem os direitos sociais por seu matiz prestacional. Neste artigo, de abordagem qualitativa e metodologia dedutiva, postula-se desconstrui-los. Observa-se, inicialmente, que as políticas públicas se convertem em leis, atos normativos infraconstitucionais e contratos perante o Judiciário, logo, afastam-se os argumentos de segregá-los da aferição judicial. Em seguida, demonstra-se que, embora sociais, estes direitos comportam uma face subjetiva, apta a assegurar o acesso e respostas individuais na sua concretização. Aponta-se, ademais, a falsa necessidade de justificá-los, quer pelo acervo principiológico constitucional, quer pelo Direito Comparado. Direitos sociais compõem direitos fundamentais, passiveis de remédios individuais e objeto de controle judicial.
A inconstitucionalidade da criminalização da assistência ao suicídio e o teste da proporcionalidade: uma perspectiva comparada de cortes constitucionais
Authors: Gavião Filho Anizio Pires , Lyra José Francisco Dias da Costa
Published: November 2024

O presente texto pretende analisar, desde a perspectiva do teste da proporcionalidade, a punição da assistência ao suicídio estabelecida pelo legislador brasileiro, procurando-se demonstrar, com base num diálogo das fontes constitucionais, que o marco punitivo é inconstitucional, por violar o princípio da autonomia individual e, pois, a dignidade da pessoa humana do paciente que se encontra em estado terminal e, por isso, decide pôr termo à sua existência. Será que um paciente gravemente enfermo – padecendo de intenso sofrimento – não possui autonomia para decidir não continuar vivendo? Todo e qualquer auxílio a ele prestado constitui delito, uma modalidade de assistência delitiva, na forma do art. 122, caput, da CPB? Não há uma restrição excessiva aos direitos de liberdade e de autonomia? Questões que irão nortear o artigo e que auxiliarão na elaboração das possíveis respostas serão desenvolvidas no corpo do trabalho. Para tanto, primeiro, revisita-se o princípio da dignidade da pessoa humana, em seguida analisa-se as decisões dos tribunais constitucionais de diversos países sobre o tema. Por último, submete-se o marco punitivo ao teste da proporcionalidade. Trata-se de uma pesquisa bibliográfica e jurisprudencial comparativa, desenvolvida com base no método dedutivo e exploratório.

The spatial distribution of zooplankton and hydrographical variables was investigated in the larger river estuaries of the Jureia-Itatins Ecological Station and compared through multivariate analysis. The distribution of most abiotic and biotic descriptors paralleled the salinity gradient, which explained a high percentage of the observed variance. The low-salinity stretches of clearwater rivers presented low phosphorus and nitrogen but comparatively high silicate concentrations, the opposite occurring in equivalent areas of blackwater rivers. Distinct zooplanktonic associations occurred in each river estuary. The copepod Pseudodiaptomus richardi dominated in the inner reaches of Guarau and Una rivers, but this species was accompanied by different associations in each of these systems. No freshwater or typical estuarine species occurred in Verde River estuary. Only slight differences were observed between Guarau and Una River estuaries regarding the estuarine-marine and marine-euryhaline biota. On the other hand, the dominant estuarine-marine species that occurred in Verde River estuary were not abundant in the other estuaries. The present results suggest a major influence of chemical properties and river size on the distribution of estuarine Zooplankton communities along the Brazilian coast.
Benthic macrofauna of Spartina alterniflora marshes and nearby unvegetated tidal flats of Paranagua Bay (SE Brazil)

Published: November 2024

The composition and distribution of benthic macro fauna in Spartirui alterniflora marshes and nearby unvegetated tidal flats of Paranagua Bay (SE, Brazil) were investigated. Samples were taken along a salinity and physical gradient, from the inner to the outer bay. The bay was divided into sectors according to its physico-chemical and faunal characteristics. Salt marshes were affected by the gradient, with the tallest formations developing in the mesohaline sector and the lowest ones in the euhaline sector. Macrobenthic associations were also affected, with the mesohaline sector presenting a low species richness of predominantly epibenthie forms. In this sector, the composition and abundance of benthic macrofauna of the salt marshes and unvegetated flats were distinct. Species richness of the polyhaline sector, particularly of the infaunal taxa, was higher than that of the mesohaline sector. Differences between the fauna of marshes and flats became increasingly evident towards the euhaline, high energy sector, characterized by the highest species richness along the bay. Benthic associations from marshes and unvegetated flats were clearly structured by the salinity and physical gradient. Although salt marsh and flats present a relative homogeneity in physico-chemical parameters, the composition and abundance of associated benthic fauna can vary widely, particularly in poly- and euhaline sectors.

Published: November 2024

As características da pesca e do pescador de corrupto (Callichirus major) foram estudadas ao longo de um ciclo anual, a partir de censos e entrevistas realizadas numa faixa de 1 lkm de praia, entre o Balneário de Pontal do Sul e o de Shangrilá, no litoral do Paraná. A faixa foi dividida em cinco setores e percorrida a cada três dias, de dezembro de 1994 a dezembro de 1995. Os resultados indicaram diferenças significativas entre o número de pescadores, as épocas do ano, os dias da semana e os setores das praias analisados. A época de maior extração foi a denominada de temporada (de 24 de dezembro até 10 de fevereiro), sendo os dias de final de semana e feriados os preferidos pelos pescadores. Os setores mais freqüentados foram aqueles de mais fácil acesso. O corrupto representa uma isca alternativa para 59% dos pescadores entrevistados. Embora 14% dos entrevistados achem que está havendo uma diminuição do recurso, 73% manifestaram-se favoráveis à colocação de um limite máximo na captura de corruptos por pescador por dia. Para o período estudado, foi estimada uma extração total de 251.041 corruptos. Destaca-se que, pelas características da pescaria, a comercialização da isca através da extração feita por profissionais levaria a um considerável aumento no esforço atual de pesca.

Authors: Capitanio Fabiana Lía , Esnal Graciela Beatriz
Published: November 2024

Appendicularians from the Rio de la Plata estuary and southern coastal areas from 34° to 41°S, Argentina were studied. Three species were found: Oikopleura fusiformis, O. dioica, and Fritillaria borealis. O. fusiformis showed a pronounced preference for outer shelf waters (33.5 %o salinity), being dominant at the Uruguayan coast. O. dioica was mainly found at coastal stations and its abundance was higher in waters with salinities between 25 and 27 %c. F. borealis appeared at very low densities, generally associated with O. dioica. No appendicularians were found at the mouth of the estuary with high concentrations of suspended sediments. Trunk lengths of individuals of each species from three areas with very different hydrological features, were compared to analyze size differences among animals showing the same maturity degree. The northern part of the estuary was characterized by the predominance of large individuals, forming a significantly different group from that of the southern area. Small individuals were predominant at the southern area, which showed marked stratifications of temperature and salinity. Histological sections of gonads of small animals with mature appearance from the southern area showed the same maturity degree as the larger mature specimens from the northern areas. The relationship between size differences and environmental factors is discussed.
Papel dos crustáceos braquiúros na rede trófica da plataforma interna de Ubatuba, São Paulo (Brasil)

Published: November 2024

Os braquiúros ocupam uma posição de destaque na comunidade da epifauna bentônica do infralitoral de Ubatuba, sendo o conhecimento de seu papel na rede trófíca elemento essencial para a compreensão da estrutura e dinâmica deste ecossistema. Examinou-se o conteúdo estomacal de 2516 exemplares das 5 espécies mais abundantes da área em profundidades de 15 a 50 metros: Persephona mediterrânea, Portunus spinimanus, Callinectes omatus, Libinia spinosa e Hepatus pudibundus. As coletas foram efetuadas com rede de arrasto de portas, a partir de outubro de 1985, com periodicidade sazonal, até julho de 1986. Coletas adicionais foram realizadas no verão e inverno de 1987 a 30 m de profundidade. As espécies de braquiúros apresentaram dietas distintas baseadas principalmente em camarões, poliquetas e caranguejos. A proporção com que os itens ocorreram nos estômagos dos braquiúros esteve relacionada com a disponibilidade da presa no local, sendo registradas importantes variações sazonais. Os braquiúros apresentaram um hábito carnívoro, sendo impossível enquadrá-los em um único nível trófico. Estes animais têm um papel fundamental na transferência eficiente de energia, já que em sua dieta generalista, incluem também animais de níveis tróficos inferiores. Os exemplares adultos de maior tamanho parecem ser predadores de topo do ecossistema estudado.
Effects of water movement and sedimentation on the community structure of scleractinian corals, St. John, Virgin Islands (United States)
Authors: Rivera Guillermo L
Published: November 2024

The community structure o f corals o f Yawzi Point and Lesser Lameshur Bay, St. John, U.S.V.I. was defined in terms of species, number of colonies, percentage of living cover, Shannon and Weaver’s diversity index, and Pielou’s index of evenness. Transects o f 10 meters long were used in the present study. They were located at four and six meters depth at both sites. Yawzi Point proved to have lower sedimentation rates (6.4 mg/cm2/day) and greater water movement. This site showed a greater number of species and colonies as well as a higher percentage of coverage and diversity index (% cover = 53 and 57% and H’n= 2.156 and 2.253 for both depths, respectively). Lesser Lameshur Bay has higher sedimentation rates (9.6 mg/cm2/day) and lower water movement. This site displayed lower number o f species and colonies as well as inferior percentage of cover (% cover =31.8 and 31.4 % and H’n= 1.670 and 1.732 for both depths, respectively). It is suggested that sedimentation and water movement affect the structure of studied communities. A total number o f 22 scleractinian species were found in the area; the four most common species were Montastrea annularis, Porites astreoides and Agaricia agaricites, as well as the hydrozoan Millepora alcicornis.
Nitrogen, Phosphorus and granulometric characterization in nearshore sediments of Guanabara Bay: tentative application of a solid phase diagenetic model
Authors: Souza Marcelo F Landim de , Mayr Leticia M
Published: November 2024

Total nitrogen, phosphorus and organic carbon were measured in sediment profiles, and correlated to granulometric distribution in different depth levels o f nearshore sediments in Guanabara Bay (Brazil). This paper assesses the pool o f these elements and the influence of sedimentary dynamics on it, in five different depositional environments. Textural parameters exhibit vertical changes in three stations. This is an evidence of changes in depositional processes, reflected by anomalous nutrient profiles. However, there was no correlation with granulometry, showing rather an erratic behaviour. Surficial sediment TN and TP ranged from 0.56 to 6.00 mg. g’1 and0.15to 1.62mg.g-1, respectively. Tentative application of solid phase diagenetic model estimates fluxes of about 1.1 - 24.7 g P . m*2 . y'1 and 2.2 - 67.2 g N . m‘2 . y'1. These values correspond to 4 - 82% o f phosphorus and 2 - 45% of nitrogen annual average phytoplanktonic demand.
Influência da gramínea Spartina alterniflora sobre a distribuição e densidade de Neritina virginea (Gastropoda:Neritidae) em marismas da Baía de Paranaguá (Paraná, Brasil)

Published: November 2024

Este trabalho analisa a influência da gramínea Spartina alterniflora sobre a distribuição e densidade do gastrópodo Neritina virginea em marismas distribuídas ao longo de um gradiente de energia ambiental na Baía de Paranaguá, no verão e invemo de 1992. Densidades populacionais de N. virginea não estão diretamente correlacionadas com o gradiente ambiental, mas são afetadas pela densidade e altura média da cobertura vegetal. Não foram registradas diferenças sazonais significativas na densidade do gastrópodo, provavelmente devido à ausência de recrutamento durante o período considerado. Foram constatadas correlações lineares significativas entre as densidades de N. virgínea e a biomassa de S. alterniflora. No entanto, estas relações são provavelmente muito mais complexas e possivelmente envolvem outros fatores, como a intensidade de predação, a disponibilidade de detritos e a taxa de recrutamento.
