Three combustion reactions in a single EA/IRMS acquisition as a strategy to save helium and energy
Authors: Spangenberg Jorge
Published: September 2023

RATIONALE: Helium (He) is used in cutting-edge research in industry and
science as a carrier and/or ionization gas. The global He shortages have
dramatically increased its prices and reduced its availability, to what
comes together the current energy crisis. A strategy is proposed to save
He and energy in elemental analysis/isotope ratio mass spectrometry
(EA/IRMS). METHODS: A method for analysis of carbon and nitrogen isotope
composition (δC and δN values)
is proposed using two or three sequential combustion reactions in a
single EA/IRMS acquisition. The methods (hereafter called 2×EA/IRMS and
3×EA/IRMS) use the time needed for the peak center and reference gas
(CO or N) pulses to measure
δC or δN in two or three
capsules with samples or standards. The combustion cycles can be
replicate analyses of the same or different material. RESULTS: The
methods were validated with replicate analysis of C and N in RMs and
laboratory standards of a broad range of biological and geological
matrices, δC and δN values, and
C/N molar ratios. The accuracy and precision of the 2×EA/IRMS and
3×EA/IRMS values were15 essentially the same, with good agreement
between the mean ± 1 SD values from RMs and standard analyses and the
recommended or accepted values and their uncertainties. CONCLUSIONS: The
proposed methods save He, save energy, save reference gases
(CO, N), and O, while
reducing the analysis and instrumental times by ca. 50 %.
The Earth planetary albedo surge in December 2020 validated using a weather prediction model
Authors: Vasiuta Maksym , Tuppi Lauri , Penttilä Antti , Muinonen Karri , Järvinen Heikki
Published: September 2023

The focus here is on the Earth’s planetary albedo estimates derived from
the data of Earth Polychromatic Imaging Camera (EPIC) onboard NOAA’s
Deep Space Climate Observatory (DSCOVR). The estimates indicate a
short-lived albedo surge with an instantaneous value of $0.350$ on the
5th of December 2020 and a 5-day average above $0.330$. A numerical
weather prediction model-based (OpenIFS of ECMWF) estimate confirms the
EPIC-based maximum in December 2020 but remains notably lower (maximum
at $0.327$). The discrepancy may be explained by the
Earth–Satellite–Sun geometry since the DSCOVR satellite was very near
the Lagrange point L1 and received the Earth outgoing short-wave
radiation close to backscattering. In this conditions, the angular
distribution model based on Clouds and the Earth’s Radiant Energy System
(CERES) and the associated footprint identification are prone to
uncertainties.
Quantifying numerical mixing in a tidally forced global eddy-permitting ocean model
Authors: Megann Alex
Published: September 2023

An ensemble of experiments based on a ¼° global NEMO configuration is
presented, including tidally forced and non-tidal simulations, and using
both the default z* geopotential vertical coordinate and the
z~ filtered Arbitrary Lagrangian-Eulerian coordinate,
the latter being known to reduce numerical mixing. This is used to
investigate the sensitivity of numerical mixing, and the resulting model
drifts and biases, to both tidal forcing and the choice of vertical
coordinate. The model is found to simulate an acceptably realistic
external tide, and the first-mode internal tide has a spatial
distribution consistent with estimates from observations and
high-resolution tidal models, with vertical velocities in the internal
tide of over 50 meters per day. Tidal forcing with the z* coordinate
increases numerical mixing in the upper ocean between 30°S and 30°N
where strong internal tides occur, while the z~
coordinate substantially reduces numerical mixing and biases in tidal
simulations to levels below those in the z* non-tidal control. The
implications for the next generation of climate models are discussed.
A multi-algorithm approach for modeling coastal wetland eco-geomorphology
Authors: Tan Zeli , Leung L. Ruby , Liao Chang , Carniello Luca , Rodriguez Jose F. , Saco Patricia M. , Sandi Steven G.
Published: September 2023

Coastal wetlands play an important role in the global water and
biogeochemical cycles. Climate change is making them more difficult to
adapt to the fluctuation of sea levels and other environment changes.
Given the importance of eco-geomorphological processes for coastal
wetland resilience, many eco-geomorphology models differing in
complexity and numerical schemes have been developed in recent decades.
But their divergent estimates on the response of coastal wetlands to
climate change indicate that substantial structural uncertainties exist
in these models. To investigate the structural uncertainty of coastal
wetland eco-geomorphology models, we developed a multi-algorithm model
framework of eco-geomorphological processes, such as mineral accretion
and organic matter accretion, within a single hydrodynamics model. The
framework is designed to explore possible ways to represent coastal
wetland eco-geomorphology in Earth system models and reduce the related
uncertainties in global applications. We tested this model framework at
three representative coastal wetland sites: two saltmarsh wetland
(Venice Lagoon and Plum Island Estuary) and a mangrove wetland (Hunter
Estuary). Through the model-data comparison, we showed the importance to
use a multi-algorithm ensemble approach for more robust predictions of
the evolution of coastal wetlands. We also find that more observations
of mineral and organic matter accretion at different elevations of
coastal wetlands and evaluation of the coastal wetland models at
different sites of diverse environments can help reduce the model
uncertainty.
Engziehungen durch Grenzziehungen
Authors: Thein Christian
Published: September 2023

In dem folgenden Beitrag wird Drerups Vorschlag einer Koppelung des politischen mit dem wissenschaftlichen Kriterium zur Bestimmung von Grenzziehungen zwischen kontroversem und direktivem Unterrichten kritisch diskutiert. Der Autor identifiziert zum einen aus philosophischer Perspektive eine unzureichende epistemische und semantische Analyse des dem pädagogischen Ansatz zugrundeliegenden Verständnisses von ‚Kontroversität‘, das sich gerade auch auf die von Drerup selbst gesetzten politischen und epistemischen Prinzipien beziehen müsste. Aus didaktischer Perspektive kritisiert der Autor zum anderen, dass der pädagogische Ansatz ausschließlich von oben – also entweder aus der wissenschaftlichen Beobachterperspektive oder von Seiten der Handlungsoptionen der Lehrkraft – über die Grenzziehungen mit Blick auf Themen, Fragen und Positionen auf der Gegenstandsebene des schulunterrichtlichen Diskurses befindet, statt die Lernenden als Subjekte der mit dem Thema nach den Grenzen der Kontroversität selbst aufgeworfenen Fragestellungen mitzudenken.
Kontroversität in der politischen Bildung
Authors: Bechtel Theresa , Schrader Arne , Lange Dirk
Published: September 2023

In diesem Beitrag kommentieren die Autor:innen zunächst den von Drerup entwickelten Orientierungsrahmen und folgen den basalen Schlüssen des Autoren, zeigen aber auch Leerstellen und eigene Schwerpunktsetzungen auf. Der kritische Teil des Beitrags konzentriert sich auf die Kommentierung der Leitlinien für die Unterrichtspraxis für Lehrkräfte, die von Johannes Drerup zur als Hilfestellung für Lehrkräfte als Basis für einen am Kontroversitätsgebot orientierten Unterricht entwickelt wurden. Das diesen Leitlinien inhärente Vorhaben Drerups, den zweiten Grundsatz des Beutelsbacher Konsens’ zu konkretisieren, wird aus Sicht der Autor:innen diskutiert. Sie zeigen auf, welche Grenzen gültiger Meinungen in der Rezeption des Beutelsbacher Konsens’ bereits formuliert wurden, um „radikal offene Kontroversitätspostulate” zu vermeiden. Die Autor:innen argumentieren außerdem gegen das von Drerup angelegte Bildungsverständnis der Demokratieerziehung und dem darin angelegten Rollenkonzept von Lehrer:innen als wissen(schaft)svermittelnde Akteure, die im Zentrum des Unterrichts stehen. Diese zugrundeliegende Prämisse hat aus Sicht der Autor:innen ungünstige Konsequenzen und führt zu einer verengten Perspektive auf die Lehrkraft. Die Autor:innen plädieren vielmehr für eine subjektorientierte Bildung, die die Lernenden und ihre mitgebrachten Konzepte und Vorstellungen in den Mittelpunkt stellt und nicht die Rolle der Lehrkraft. So kann der Blick geweitet werden für die Potenziale, die die Demokratiebildung bereit hält.
Anmerkungen zu Drerups politischem Kriterium für legitime Kontroversen im Unterricht
Authors: Frick Marie-Luisa
Published: September 2023

Johannes Drerup schlägt für normativ-politische Kontroversen ein Kriterium vor, anhand dessen bestimmt werden soll, wann diese Kontroversen legitime Unterrichtsthemen sind und in Folge dem Kontroversitätsgebot unterliegen. Dies ist dann der Fall, wenn für kontroverse Fragen „auf Basis politischer Grundwerte und -prinzipien, die als konstitutiv gelten können für die Ermöglichung eines guten persönlichen und politischen Lebens in liberal-demokratischen Staaten, keine eindeutige Antwort abgeleitet werden kann.“ Zu diesen Grundwerten und -prinzipien zählt Drerup auch „Grund- und Menschenechte“. Mein kurzer Beitrag möchte zeigen, weshalb Drerups an sich fruchtbarer Ansatz die Komplexität des Maßstabes „Grundund Menschenrechte“ tendenziell unterschätzt und insbesondere das Verhältnis von Demokratie und Menschenrechten zu wenig als potenzielles Spannungsverhältnis ernst nimmt. Ich schlage daher weitere Differenzierungen vor, um Drerups Kriterium konzeptionell zu schärfen. Zudem rege ich an, Kontroversen, die Drerups Kriterium nicht genügen, aus didaktischen Gründen dennoch eine gewisse Anfangs-Kontroversität zuzugestehen, um die Bedeutung der betreffenden Grundprinzipien, die als „rote Linien“ fungieren, deutlicher herausarbeiten zu können.
Ein gutes Leben muss keine Geschichte erzählen
Authors: Nguyen Anh Quan
Published: September 2023

Philosoph:innen versuchen zunehmend zu erklären, warum die Struktur unseres Lebens normativ bedeutsam ist. Eine beliebte Erklärung, die von Dorsey (2015), Rosati (2013), Glasgow (2013), Kauppinnen (2012) und Velleman (1991) vertreten wird, ist die Narrativitäts-These: Was der Struktur unseres Lebens normative Bedeutung verleiht, sind die narrativen Relationen zwischen Lebensabschnitten, die verschiedene Teile des Lebens einer Person zu etwas Sinnhaftem verbinden. Sie fügen einem Leben einen Wert hinzu, der nicht auf momentanes Wohlbefinden reduziert werden kann. Da die narrative Lebensstruktur normative Bedeutung hat, ist ein Leben mit narrativen Relationen wertvoller als ein Leben ohne diese Beziehungen, da es mehr Sinnhaftigkeit erlangt. Mit anderen Worten: Unter sonst gleichen Bedingungen sollten wir unser Leben als Geschichte leben. In diesem Beitrag wird argumentiert, dass die Narrativitäts-These falsch ist. Weder ist ein Leben besser, wenn es eine Geschichte erzählt, noch müssen wir unser Leben als eine Geschichte leben. Ich zeige drei Fälle, in denen wir intuitiv nicht der Narrativitäts-These folgen sollten, und gebe anschließend eine systematische Erklärung, warum narrative Beziehungen zwischen Lebensabschnitten normativ nicht bedeutsam sind: Es ist rational, uns von unserer Vergangenheit abzukoppeln und vergangenen Ereignissen und Lebensabschnitten keine normative Bedeutung beizumessen. Ich schließe mit einer Diskussion über Verdrängung und narrative Fehlschlüsse über wichtige Teile unserer Vergangenheit und wie wir uns vor beidem schützen können.
Theoretical assessment of sustainable soil management practices and their contribution to achieving farm and climate goals
Authors:   Latvia University of Life Sciences and Technologies, Latvia, Liva Diana , Zvirbule Andra ,   Latvia University of Life Sciences and Technologies, Latvia
Published: September 2023

The new European strategy envisages addressing the problems of climate change, which significantly affects the agricultural sector, as, for example, in Latvia it accounts for 22% of all greenhouse gas emissions. However, the data show that since joining the European Union, the main objective has been to increase the productivity of the sector. Therefore, in order to achieve the set climate goals, it is necessary to evaluate the implementation of practices corresponding to the goals set, where, as part of this study, we examine the theoretical benefits of sustainable soil management, as well as evaluate the information available in literature sources about the current situation. The data show that currently, the implementation of such practices is in the process, as it has been observed that it is affected by both technical and financial problems, where it is expected that the implementation of these practices will increase. As well as it is concluded that sustainable soil management practices ensure the achievement of goals of different categories - financial, environmental, and social. Therefore, to objectively evaluate the benefits, a complex approach is needed.
Investigation of the effects on engine performance and emissions of ZnFe2O4 and ZnCO3 nanoparticle additives in a diesel engine
Authors: Cinar Gursel
Published: September 2023

In this study, engine performance and emissions effects of ZnFe2O4 and ZnCO3
nanoparticle additives have been investigated in a Diesel engine. The
experiments have been carried out at 600 rpm and different loads (250-380
Nm) in a 11670 cc heavy-duty Diesel engine. Mixtures of additives have been
applied to diesel fuel as 100 ppm. Brake thermal efficiency, cylinder
pressure, and emission values have been tested for all investigated fuel
mixtures. The maximum thermal efficiency values of D-ZnCO3-100 and
D-ZnFe2O4-50 are higher than diesel fuel. Also, CO emission values of
D-ZnCO3-100 and D-ZnFe2O4-50 are obtained as less than diesel fuel.

Published: September 2023

This study contains an algorithmic solution of the Sine Gordon equation in
three space and time dimensional problems. For discretization, the central
difference formula is used for the time variable. In contrast, space
variable x, y, and z are discretized using the non-polynominal cubic spline
functions for each. The proposed scheme brings the accuracy of order O(h2 +
k2 + ?2 + ?2h2 + ?2k2 + ?2?2) by electing suitable parametric values. The
paper also discussed the truncation error of the proposed method and
obtained the stability analysis. Numerical problems are elucidated by this
method and compared to results taken from the literature.
Comparison of side collision analyzes of electric vehicle and conventional vehicle chassis
Authors: Cimendag Muhammed , Yilmaz Ulu Eylem
Published: September 2023

Conventional vehicles use fossil fuels, which leads to the emission of CO,
causing environmental harm. Due to the damage caused by this gas to the
environment and human health, the interest in hybrid or electric cars that
can use RES has increased. Parts like powertrains, which are found in
conventional vehicles but not in electric ones, have caused design
disparities in their respective chassis. This study aims to investigate the
load distribution on the chassis of electric and conventional vehicles in
the event of a side collision. After conducting a literature review and
engineering calculations, a chassis was designed for both types of vehicles
using the SOLIDWORKS program. The completed chassis was analyzed at a speed
of 40 km/h, taking the average of the speed limits determined in the side
impact test and polar impact test in the EXPLICIT module of the ANSYS
WORK-BENCH program. Due to the load generated during the collision, a
deformation of 150.72 mm occurred in the electric vehicle chassis and 403.78
mm in the conventional vehicle chassis. As a result of the deformations,
stress of 1228.2 MPa occurred in the electric vehicle chassis base and
1000.2 MPa occurred in the conventional vehicle chassis base. These stresses
exceeded the yield limit on the designed chassis bases, causing a permanent
shape change in both vehicles, but no rupture occurred.

Published: September 2023

The main purpose of this study is to enhance the performance of solid oxide
fuel cell systems. For this purpose, a mathematical model of a direct
internal reforming (DIR) methane-fed solid oxide fuel cell system with
waste heat recovery was designed in the engineering equation solver program.
We optimised the performance of the solid oxide fuel cell using a genetic
algorithm and TOPSIS technique considering exergy, power, and environmental
analyzes. An ANN working with the Levenberg-Marquardt training function was
designed in the MATLprogram to create the decision matrix to which the
TOPSIS method will be applied. According to the power optimization, 786 kW
net power was obtained from the system. In exergetic optimization, the
exergy efficiency was found to be 57.6%. In environmental optimization, the
environmental impact was determined as 330.6 kgCO2/MWh. According to the
multi-objective optimization results, the exergy efficiency, the net power
of the solid oxide fuel cell system, and the environmental impact were
504.1 kW, 40.08%, and 475.4 kgCO2/MWh.

Published: September 2023

Natural gas, which is also referred to as eco-friendly fuel, is being seen as
a potential solution to challenge the decline of crude oil resources and
the deteriorating air quality in urban areas. This fuel has been verified
to emit less CO, HC, and PM compared to other fuels. A potential approach to
reducing NOx and soot emissions while also achieving low fuel consumption is
the low temperature combustion process. In this study, internal combustion
engines were simulated under various conditions. The objective was to
investigate the effect of different operating variables on the low
temperature combustion mode. To begin with, a natural gas powered engine was
modeled using complex chemical kinetics software. The outcomes of the
simulation were then compared to experimental data, demonstrating a high
level of agreement. Subsequently, the impacts of key variables, including
the air-fuel ratio, compression ratio, and engine speed, were analyzed using
a cycle simulation code. Increasing the compression ratio improves engine
performance, and the specific fuel consumption decreases. However, it leads
to a significant increase in NOx emissions until a certain value.
Thereafter, it changes the trend. Engine speed indirectly affects
performance by increasing fuel consumption and changing ignition timing. A
leaner air fuel ration may be used to produce more power and keep the
temperature of combustion below a certain value (low-temperature
combustion), ensuring low NOx emissions.
Neonatal multisystem inflammatory syndrome during acute SARS-CoV-2 infection
Authors: Jaric Milica , Katic Katarina , Djuretic Andrea , Stojanovic Vesna , Milojkovic Milica
Published: September 2023

Introduction. During the development and spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic, a new inflammatory response syndrome arose in newborns, defined as the multisystem inflammatory syndrome (MIS) in neonates (MIS-N). Case report. A term infant girl with a fever diagnosed with SARS-CoV-2 infection was admitted to the hospital. In laboratory findings, the values of lactate dehydrogenase, ferritin, interleukin-6, and D-dimer were elevated. Upon admission, dual parenteral antibiotic therapy (ceftazidime, vancomycin), and one day later, low molecular weight heparin (LMWH) therapy, was commenced. After five days of hospitalization and febrility, with negative results of microbiological analyses and further deterioration of laboratory findings, intravenous immuno-globulin (IVIg) was administered at a dose of 2 g/kg for one day and methylprednisolone at a dose of 1 mg/kg/day for four days, after which the reduction of corticosteroid therapy was continued with prednisone. One day after IVIg dministration, the newborn became afebrile, with the gradual normalization of laboratory findings. The newborn was discharged after 16 days of hospitalization. Ten days after discharge, prednisone therapy was discontinued. Two weeks after discharge, the administration of heparin was discontinued. Seven days later, the D-dimer value increased significantly, and the anticoagulant therapy was reinstated. After one month, the D-dimer value completely normalized, and the LMWH therapy was discontinued. Conclusion. After the applied therapy for MIS in children, there was a cessation of febrility and gradual normalization of values of the laboratory parameters. This confirms that the new-born, in this case, probably had MIS-N. The prolonged elevated D-dimer value was most probably a consequence of the MIS.
The Conservatism Principle and Asymmetric Preferences over Reporting Errors
Authors: Chakravarthy Jivas , Shields Timothy W.
Published: September 2023

Accounting conservatism has been described as deriving from preferences for reporting errors to be in the direction of understatement rather than overstatement. We pair reporters with users (who rely on reporters’ information) in a multiperiod experiment. We posit that, under misaligned incentives that motivate aggressive reporting, users view aggressive reports as reflecting exploitative intent and expect that a norm prohibiting aggressive reporting applies. We predict that users use noisy reporting errors to gauge reporters’ norm compliance. We find that, ceteris paribus, users prefer not to be paired with reporters producing overstatement errors likely to reflect aggressive reporting relative to reporters producing understatement errors likely to reflect conservative reporting; alternatively, we find no such asymmetric preferences when the agents’ motives are aligned. The asymmetric preferences cannot be explained by agency theory predictions of payoff maximization or loss aversion. These moral preferences provide an initial condition from which conservatism can endogenously emerge.

Disturbing the Quiet Life? Competition and CEO Incentives
Authors: Kramer Stephan , Matějka Michal
Published: September 2023

Although it is well understood that product market competition acts as a disciplining mechanism that reduces inefficiencies, our understanding of the implications for firms’ incentive design choices is still limited. We use a comprehensive new measure of competition and examine its effect on four major choices: CEO equity portfolio incentives, annual bonus plan incentives, choice of performance measures, and difficulty of financial performance targets. We find that competition reduces firm profits and total CEO compensation, including equity grants, which then also weakens portfolio incentives. Firms respond by adjusting annual bonus plans to restore incentives. Specifically, we find that competition goes together with stronger bonus plan incentives, more challenging annual performance targets, and a greater emphasis on long-term performance measures. Finally, we show that competition increases performance relative to annual bonus targets, which we interpret as evidence that CEOs work harder but get paid less in highly competitive environments.

A Review on Reverse Osmosis Membrane Fouling Diagnosis
Authors: Liu Mu
Published: September 2023

During long-term operation, reverse osmosis (RO) membrane fouling is an inevitable occurrence that leads to a decline in membrane performance. When the water quality fails to meet specific application requirements, it becomes necessary to replace the deteriorated membranes. Membrane autopsy is widely recognized as the most direct and effective method for studying and identifying membrane fouling. By analyzing the results of membrane autopsy and membrane fouling diagnosis, valuable insights can be gained to optimize the operation of the membrane system, maintain the membrane elements through regular routines, and restore membrane performance. However, the current practice of membrane autopsy and the study of membrane fouling diagnosis lack a systematic and comprehensive approach. This paper aims to address these gaps by introducing various analytical methods for membrane fouling, discussing the existing challenges in practical applications, and reviewing the diagnosis of fouling composition. These findings are expected to shed light on understanding the mechanisms and control methods of membrane fouling, and ultimately enhance the operation of membrane systems.
Mini-Review on Molecular Markers for the Identification of Fish Nematode Parasites
Authors: Iqbal Gowhar
Published: September 2023

A parasite is an organism that survives in or on another species, usually at the expense of its host. Among the fish-infecting parasites, three types of helminth parasites, namely, roundworms (nematodes), flatworms or flukes (trematodes), and tapeworms (cestodes), have the potential to cause zoonotic diseases. A large diversity of parasites that are taxonomically diverse and display a wide range of life cycle methods live on fish as hosts. While many of these parasites are transmitted straight from ultimate host to ultimate host, some must travel through several intermediate hosts before finding a host in (or on) whom they can reach sexual maturity. There are various methods for detecting nematode parasites in various fish species like internal transcribed spacers (ITS), mitochondrial COI, RFLP, AFLP etc. There are various Reports of nematode infection in fish and humans. Accurate identification of fish parasites is crucial to study the host-environment relations and formulate subsequent preventive strategies.
The Microorganism Concern in the Aquaponics System
Authors: Lin Han Tso
Published: September 2023

Aquaponics system (AP) is a promising form for mass-produced food in the future. The system reduces the mass water demand for food production. It solves the problem of nitrogenous waste removal from the recirculating aquaculture systems (RAS) by connecting with the hydroponic system (HP) in series. Microorganisms are essential in biochemical activities in an aquaculture system, such as nitrogen cycling, waste decomposition, and detoxification. However, excessive microorganisms in the system will increase the disease risk for aquatic organisms and plants. In the RAS system, high-density breeding enriches nutrients. That microbial management is even more critical. Through the design of zone isolation, the system confines different biochemical reactions to specific intervals, enhances its performance by shaping the dominant bacterial phase with environmental advantages, and simultaneously reduces the disturbance of microorganisms to the cultured organisms. Aquaponics farming, which emphasizes the symbiotic relationship between plants, aquatic organisms, and microorganisms, would create a more diverse and complex microbiota than the RAS system. Relevant studies have shown that the uncoupled aquaponics system using microbial zone management may be the right way to reduce management risks and increase production capacity. Research on the microbial phase of aquaponic systems is still minimal; limited research shows that the microbiota in the aquaponics system may vary considerably with the seasons and the geographical location of the farm. More active bacterial research and the establishment of effective management measures are the core technologies of future aquaculture management.
Basal Cell Carcinoma of the Prostate: Case Reports Including an Unusual Presentation
Authors: Chesnut Gregory T
Published: September 2023

Basal cell carcinoma of the prostate is a rare tumor subtype arising from the prostatic basal cells and follows a variable clinical course. We describe two cases of patients with basal cell carcinoma of the prostate treated at our center. One case involves a patient with prior radiation with brachytherapy for prostatic adenocarcinoma, who subsequently developed a locally aggressive and invasive basal cell carcinoma of the prostate that eventually required pelvic exenteration. To our knowledge, we are the first to describe a case of basal cell carcinoma of the prostate in a patient with prior radiation with brachytherapy for prostatic adenocarcinoma.
Fragilidade estatal e terrorismo
Authors: Mendes Cristiano
Published: September 2023

O artigo visa saber se há algum tipo de relação entre fragilidade estatal e atividades terroristas. Partindo da hipótese de que estas duas variáveis não possuem relação de causalidade, esta pesquisa comparou os índices de fragilidade estatal do Fragile States Index (do Fundo para a Paz), com o impacto do terrorismo nestes Estados (frágeis), segundo os números do Global Terrorism Index (do Institute for Economics and Peace). Comparando os dados dos últimos dez anos, tanto dos Estados que mais aumentaram sua fragilidade neste período, como dos Estados mais impactados pelo terrorismo, o estudo concluiu que não é possível notar relações de causalidade entre o aumento de fragilidade estatal e o alto impacto de atividades terroristas.
Hino da Terceira Internacional em Rituais Revolucionários no Brasil
Authors: Sousa Rafael Lopes , Campos Alzira Lobo de Arruda , Dias Luiz Antonio
Published: September 2023

Este artigo reflete sobre a função da música em movimentos populares, em especial para a organização da massa trabalhadora, por meio do Hino da III Internacional, que significou, nos tempos heroicos da organização da esquerda brasileira, a palavra de ordem da Revolução Proletária, mesmo após a rejeição de Stálin ao internacionalismo. Nos movimentos operários que se organizaram em partidos que pretendiam uma revolução proletária, a Revolução de Outubro de 1917 tornou-se um modelo a reproduzir no Brasil, conferindo alento às vanguardas operárias e medo às elites nacionais. Nesse ambiente de polarização, certamente desigual, o hino A Internacional tornou-se parte integrante dos rituais revolucionários da esquerda paulista, funcionando como canto de combate nas passeatas e comícios dos trabalhadores. Era um modo de transmitir a ideia do internacionalismo como estratégia fundamental para a tomada de consciência sobre a exploração do trabalho pelo capital, etapa considerada necessária para a instalação posterior de uma ditadura do proletariado.

Imagen documental como posibilidad en la enseñanza del cine
Authors: García Edwin
Published: September 2023

La imagen documental se desplaza entre lo real y lo irreal. El filósofo Paul Virilio habla del acontecimiento en la imagen documental, discute la trayectoria de la imagen a la sujeción del espectáculo, dado que genera una dependencia embrionaria a lo real. Se trata, de pensar la imagen por fuera de la realidad y ver el problema de lo real en su potencia y en su debilidad, donde opera bajo el principio de simultaneidad: que el ojo vea lo que ve la cámara y se desplace hacia la trayectoria. Dicha sujeción se efectúa con la supresión de la distancia señalando la identidad de la imagen, constituida por un mostrar, formar y enseñar algo, antes que nada. De ahí, la necesidad de analizar un modo de enseñar con la imagen no reducido a una herramienta.

Este artículo resultado de investigación trata la formación intelectual de los profesores en la política pública gubernamental de integración institucional en Colombia, hacia mediados de la década del sesenta y parte de los años setenta del siglo XX para poner de relieve cómo los principios de la administración y la planeación en la adecuación social de los discursos sobre la enseñanza de la ciencia y de la técnica, se rigen bajo la consigna de hacer causa común para lograr un cambio de mentalidad y conformar una nueva generación para la convivencia social e intervenir en la organización del Sistema Nacional de Educación. Estudio basado en la construcción documental de un archivo institucional proveniente del Archivo Histórico de la Universidad Nacional de Colombia y de las memorias o informes de los ministros de educación. Se toma como referencia el análisis filosófico de Michel Foucault en “El orden del discurso” cuando habla de los saberes y los poderes en los discursos que implican, en este caso, el de la educación identificada como instrumento político, en tanto tiene que ver con la lucha social entre élite y masa, oposición entre los partidos políticos liberal y conservador y la distancia social entre civilizados e incivilizados.
Piezoelectric Endodontic Microsurgery with Modified Cortical Window Technique: A Case Report
Authors: Fernández-Grisales Rafael , Rojas Wilder , Berruecos-Orozco Carolina
Published: September 2023

Osteotomy in endodontic microsurgery for teeth with periapical lesions which have not perforated the cortical plate can be a complex procedure especially if anatomical structures such as the mental nerve are close to the area of ​​surgical intervention. For such cases, the cortical bone window technique is an excellent option to access the operating field, preserving the cortical bone and avoiding the use of other bone regeneration materials. The present case documented the use of the cortical bone window technique with a modification, due to the proximity of the mental nerve to approach a persistent periapical lesion of a mandibular second premolar with previous endodontic treatment. Cone beam tomography (CBCT) and intraoral scanning were used for planning and elaboration of a navigation guide for surgical procedure.

Sustainable development, which is defined by the United Nations through 17 goals, provides a shared blueprint for achieving peace, prosperity, and environmental well-being. Various urban projects worldwide aim to align with these sustainable goals and incorporate them into their design language. Stockholm Royal Seaport stands out as one of the largest sustainable urban developments, striving to become an international model for urban planning. Within the Stockholm Royal Seaport project, the sustainable development goals have been translated into five key strategies including vibrant city, accessibility and proximity, resource efficiency and climate responsibility, let nature do the work and participation and consultation. Here the question is whether the sustainability model works the same for developing countries. To answer, we have selected four projects in Caracas, Venezuela to compare their sustainability model with the base one from Stockholm Royal Seaport. The comparison reveals that the significance of each strategy varies in Venezuela, with some strategies being more prioritized than others. Additionally, two additional strategies, namely education and limited demolition, emerge as noteworthy and exclusive to Venezuela. By exploring these findings, we gain insights into the adaptation and customization of sustainability models in developing countries, shedding light on their unique economic and managerial perspectives.
