Authors: Pathirana Gayan , Noh Kyung-Min , Lee Dong-Geon , Park Hyo-Jin , Wang Dongxiao , Kug Jong-Seong
Published: February 2024

The Indian Ocean Dipole (IOD) has been proposed to be a key driver of biological processes in the Indian Ocean (IO) in the present climate. Given the expected influence of global warming on both the properties of the IOD and the biogeochemistry within the IO, a key question arises: How will the relationship between the IOD and chlorophyll evolve in a warming climate? Here, utilizing simulations from the Coupled Model Intercomparison Project (CMIP) Phase 6 Earth System models, our findings reveal a notable intensification in the IOD-chlorophyll relationship under greenhouse warming. This intensification is linked to an increase in phytoplankton biomass during the June to November period of positive IOD years in the southeastern IO (SEIO). Interestingly, our analysis indicates a substantial rise in IOD-induced chlorophyll levels in a warming climate, despite a marked decrease in IOD-induced upwelling in the SEIO. The shallower thermocline leads to an increase in the mean nutrient concentration in the subsurface layer, thereby facilitating an enhanced anomalous nutrient supply to the surface layer, which contributes to increased phytoplankton biomass. Our study highlights the consequential effects of IOD on chlorophyll dynamics and underscores the need for improvement of Earth System Models to resolve our understanding of biophysical interactions in the IO in response to global warming.
The impact of environmental regulations on enterprise production
Authors: Fan Xuecheng , Wang Xinxin , Xu Zeshui
Published: February 2024

As an integral part of the modern environmental governance system, environmental regulations have the potential to alter the dynamics of competition and cooperation, resulting in a phenomenon known as the “relatively better” effect. In light of this phenomenon, we have developed a static game model based on incomplete information to analyze its implications. Through the exploration of Nash equilibrium, we have discovered that the "relatively better" effect allows environmentally regulated clean enterprises to transfer a portion of their costs to polluting enterprises. Consequently, clean enterprises experience lower financing costs compared to their polluting counterparts under environmental regulation conditions. This conclusion is supported by empirical analysis conducted using Chinese enterprise data. Furthermore, our research reveals that appropriately designed environmental regulations, including the intensity of regulation and the establishment of emission rights trading systems, can contribute to improving social distribution.

Published: February 2024

Cytogenetic mechanisms of unisexuality in diploid parthenogenetic species of genusDarevskiaremained debatable until recently. The mechanism that allows the unisexual form to maintain its heterozygosity in a number of generations is important for long-term existence in nature. In this work, for the first time for a parthenogenetic species of genus Darevskia, in addition to primary oocytes with the usual ploidy (18 + ZW bivalents in the meiotic prophase I) oocytes that underwent premeiotic genome endoduplication and carry a doubled number of bivalents (36 + ZZ + WW) were found. Here we present a detailed comparative analysis of total preparation of synaptonemal complexes in the oocyte nuclei without and with genome endoduplication, and the behavior of sex Z and W chromosomes. We show the details of assembly of bivalents in the pachytene nuclei, where either homeologues or doubled identical copies of chromosomes compete for synapsis and form multivalents. For the first time, the WW sex pseudobivalent has been visualized in parthenogenetic reptiles. We show the reverse side of meiotic deviations in obligate parthenogenesis - cases of non-viable embryos with specific abnormalities.
The Effects of Annual Compost Addition to Agricultural Green Roofs on Runoff Water Quality
Authors: Whittinghill Leigh , Jackson Christine , Poudel Pradip
Published: February 2024

Space availability is one of the largest barriers to urban agriculture. One way around this issue that urban farmers in some parts of the world are exploring is moving their farming activities to building rooftops. One method of rooftop farming in use is row agriculture using green roof technology. Vegetable crop plants, which typically require more water and more nutrients than the ornamental species found on green roofs, require irrigation and the use of fertilizers. One nutrient management practice that some rooftop farmers are using is the addition of compost, which could lead to changes over time in the water-holding capacity, organic matter content, and weight of green roof media. This practice and its long-term implications have not been well-studied. Green roof platforms were created to examine how the annual additions of compost in quantities of 0, 0.33, 0.66, and 1 kg/m2 affect runoff water quality and green roof media properties. Runoff water samples were collected and analyzed for pH, conductivity, color, turbidity, and nitrate nitrogen, ammonia nitrogen, total phosphorus, and potassium contents. Compost treatment had no effect on any water quality metric except for color, which had slightly different changes over time in the different compost treatments. The lack of difference among the treatments may be attributed to the low nutrient content of the compost and continued use of fertilizers to provide nutrients. Most samples observed in this study exceeded the US Environmental Protection Agency water quality guidelines for nitrate nitrogen and phosphorus and were similar to values observed in the green roof literature regarding agricultural and ornamental green roofs. This has potential implications for surface water quality and eutrophication, especially as green roof agriculture increases.
The impact of dynamic marketing capabilities on startup performance: A case of business incubators in Jordan
Authors: Salim Khraim Hamza
Published: February 2024

Dynamic marketing capabilities provide startups with the platform and market knowledge that entitle them to achieve their goals and survive the competition. The study aims to examine the impact of dynamic marketing capabilities dimensions on startups’ performance in Jordan. This quantitative study employs a questionnaire to solicit answers from respondents who are the incubates that use business incubator services. A total of 302 entrepreneurs from different incubator centers in Jordan participated in the online survey. Using the SmartPLS program version 4, structural equation modeling (PLS-SEM) was used to examine the study model. The findings indicate that startup performance is significantly impacted by dynamic marketing capabilities (β = 0.937, t = 127.2, p = >0.00). Concerning absorptive capacity, both dimensions revealed a significant impact on startup performance: potential absorptive capacity (β = 0.251, t = 7.932, p > 0.000) and realized absorptive capacity (β = 0.177, t = 5.409, p > 0.000). For knowledge management, the results for knowledge acquisition were β = 0.360, t = 11.089, p = >0.000, for knowledge dissemination, β = 0.102, t = 2.367, p = >0.018, and for responsiveness to knowledge β = 0.318, t = 6.852, p = >0.000.
Statistical downscaling of high-resolution precipitation in India using convolutional long short-term memory networks
Authors: Misra Saptarshi , Sarkar Sudeshna , Mitra Pabitra , Shastri Hiteshri
Published: February 2024

Statistical downscaling of the General Circulation Model (GCM) simulations are widely used for accessing climate changes in the future at different spatiotemporal scales. This study proposes a novel Statistical Downscaling (SD) model established on the Convolutional Long Short-Term Memory (ConvLSTM) Network. The methodology is applied to obtain future projection of rainfall at 0.25° spatial resolution over the Indian sub-continental region. The traditional multisite downscaling models typically perform downscaling on a single homogeneous rainfall zone, predicting rainfall at only one grid point in a single model run. The proposed model captures spatiotemporal dependencies in multisite local rainfall and predicts rainfall for the entire zone in a single model run. The study proposes a Shared ConvLSTM model providing a single end-to-end supervised model for predicting the future precipitation for entire India. The model captures the regional variability in rainfall better than a region-wise trained model. The projected future rainfall for different scenarios of climate change reveals an overall increase in the rainfall mean and spatially non-uniform changes in future rainfall extremes over India. The results highlight the importance of conducting in-depth hydrologic studies for different river basins of the country for future water availability assessment and making water resource policies.
Algorithm for identifying parameters of production function models using a neural network
Authors: Chertkov A. A. , Saburov S. V. , Kask Ya. N.
Published: February 2024

The purpose of the work is to ensure the monitoring and reliability of statistical data used for the analysis and forecasting of the production development on the basis of generalized indicators that take into account the volume of resources used and the ways of their use. An algorithm for parametric identification of production functions models from time series of statistical data using generalized regression, which provides the best estimation of the parametric optimization error by the method of least squares, is proposed. In contrast to existing assessment methods, neural networks are used to build models, which significantly expand the technical capabilities of modeling and contribute to improving the accuracy of calculations through the use of neural network technologies. It is shown that in order to solve the problems of this class, it is advisable to use generalized regression neural networks with simple training modes and high modeling accuracy. As a result, it is possible to propose an algorithm for quantitative assessment of the production functions parameters, which consists in the construction of a neural model with its subsequent use to fit the trajectory of the production model of a given structure to the obtained data by means of recurrent estimates of the vector of the desired coefficients at a given initial approximation. The proposed algorithm is demonstrated by estimating the parameters of the Cobb-Douglas production function and the discrete-dynamic model of the consumption function according to the corresponding statistical series. The calculations are performed using the functions of the Neural Networks package of the MATLAB software environment. The algorithm is applicable for quantitative estimation of the production models parameters with complex logical-probabilistic relationships, as well as for obtaining numerical values of target indicators and indicators for assessing the inland water transport development by statistical series and monitoring.
Modification of the wave algorithm for Euclidean distances calculation in transport applications
Authors: Kuznetsov A. L.
Published: February 2024

Many engineering problems could be either reduced to or directly involve the mathematical problem of finding the shortest path in some confined space with obstacles. To solve this problem, graph theory and dynamic programming offers quite a lot of exact and heuristic algorithms that work with directed and undirected, weighted and unweighted, connected and disconnected graphs. All these methods are based on their own techniques of calculating the distance between the vertices, the choice of which is dictated by the convenience of implementation and methodological considerations. As a result, the resulted paths found by the algorithms usually are characterized by a certain abstract length, which is often difficult to convert into Euclidean one. Nevertheless, spatial problems in engineering practice often require an answer in terms of real physical distances. Specifically, such a task fully arises in engineering applications related to the design of seaports, namely, in the laying of routes of intra-terminal transport, power supply networks, in the design of approach channels. A modification of the most common method for finding the shortest paths, the wave orthogonal-diagonal algorithm, is described in the paper. It allows you to include the geometric characteristics of its individual sections in the calculation of the length of the found route, which makes it possible to accurately estimate the length in the sense of the Euclidean distance.

Published: February 2024

Vitamin D deficiency is a widespread global health issue, notably prevalent in the Middle East and more severe in women. Vitamin D deficiency increases the incidence of uterine fibroids in black and white women, the most frequent benign gynecologic malignancies. This study examined health-care providers’ understanding of the relationship between vitamin D insufficiency and uterine fibroid at Sulaimani Hospitals in Kurdistan, Iraq. A quantitative design, cross-sectional-descriptive study (non-probability purposive sample) of 113 female nurses and gynecologists. Data were collected using a checklist through Google Forms. The results showed that the majority of the participants were nurses (88.5%), and the remaining (11.5%) were gynecologist. Two-thirds of them work in maternity teaching hospital while others work in smart hospitals and Faroq medical cities. The results revealed that the level of knowledge was significantly associated with the position of participants and level of education (P < 0.05). As well, the study demonstrated that the majority of the participants were not trained regarding uterine fibroid and vitamin D deficiency. The study concluded that nearly a quarter of the health-care professionals had a medium level of knowledge, while nearly a quarter (24.8%) of them had a high level of knowledge. The study recommended to the Ministry of Health giving opportunities to health-care professionals, especially nurses, to participate in training courses, workshops, and conferences regarding the relationship between vitamin D deficiency and uterine fibroid.

En concordancia con esta exposición, el texto logra trazar un marco de relación de las transformaciones jurídico-políticas de los regímenes de memoria en la justicia transicional como cumplimiento del fundamento constitucional de la paz en Colombia.
Carlos S. Nino and how to Construct our Constitutions: Revisiting a Methodological Challenge of New Originalism
Authors: Laise Luciano D.
Published: February 2024

New Originalism stresses the original public meaning, not the semantic intentions of the framers. This requires a reformulation of the two main activities of every constitutional practice. First, interpretation implies discovering the original public meaning, i.e., what the ordinary users of language intended to mean through constitutional provisions. Second, constitutional construction is a subsequent stage of interpretation, as it involves giving effect or implementing those provisions, mainly if they are vague or ambiguous. In this article, I contribute to that ongoing debate by resorting to one of the most well-known law philosophers from Latin America: Carlos S: Nino. I shall claim that his scholarship may pose an actual and significant contribution to one of the toughest challenges of New Originalism: how to construct our constitutions. Although I will not label Nino as an originalist, he elaborates three requirements that could be very useful for constructing constitutional provisions: (i) to secure democratic processes; (ii) to respect individual rights, and (iii) the preservation of continuous legal practice.

El objetivo del presente estudio es determinar el nivel de transparencia y rendición de cuentas en los municipios del estado de Michoacán. La metodología empleada consiste en un análisis cuantitativo a partir del procesamiento de la información derivada del Censo Nacional de Gobiernos Municipales y Demarcaciones Territoriales de la Ciudad de México 2019 del Instituto Nacional de Estadística y Geografía. Los principales resultados muestran que el 0.9% de los municipios observa un índice de transparencia y rendición de cuentas muy bajo, mientras que el 17.3% refiere un índice bajo; por su parte, el 34.5% demuestra un índice regular; asimismo, el 43.6% observa un índice alto, y únicamente el 3.6% de los municipios manifiesta un índice muy alto. En promedio, el índice de transparencia y rendición de cuentas para los municipios de Michoacán en su conjunto es de 58.42%, lo cual muestra las limitaciones, las deficiencias y los rezagos en las capacidades institucionales municipales en este campo.
La biometría como coadyuvante en la mitigación del delito de usurpación de identidad en la práctica notarial
Authors: Ledesma Lois Florencia Aurora , Marín Aboytes Luis Arturo
Published: February 2024

La comisión del delito de usurpación de identidad se ha convertido en una actividad reiterante en México, que se actualiza principalmente dentro de la práctica notarial, cuando un sujeto suplanta la identidad de otro con el afán de acceder indebidamente a recursos a través de la celebración de actos traslativos de dominio o al allegarse de facultades de disposición sobre bienes ajenos suplantando la identidad de otros a partir del uso de instrumentos de representación, como los poderes notariales y mandatos. La hipótesis que se plantea radica en que los medios por los cuales ordinariamente se valida la identidad de los clientes en las oficinas notariales han resultado insuficientes; por lo que, se propone el uso de la biometría como coadyuvante en la mitigación el delito de usurpación de identidad y se destaca que el principal objetivo del presente comentario es la identificación de los biométricos cuya implementación es viable en la práctica notarial. El problema de investigación se aborda desde una metodología dogmático-formalista, a partir del análisis de los fenómenos que están presentes en el objeto de estudio.

Este trabajo analiza el nivel de articulación institucional y asimilación en materia de transparencia en las organizaciones gubernamentales en México, utilizando criterios de validación que permitan identificar el nivel de comprensión de los procesos de gestión pública relacionados con la transparencia en las instituciones. Se realiza un análisis cualitativo para elaborar indicadores de semáforo que muestran la permeabilidad institucional y el grado de aplicación del modelo de la nueva gerencia pública en distintas organizaciones públicas en México. Los resultados indican que la implementación de la transparencia todavía no es coincidente en cuanto al diseño y marco normativo de los procesos de transparencia. El nivel de permeabilidad institucional muestra avances limitados para socializar y transparentar los recursos públicos, que permitan empoderar a la sociedad a nuevas relaciones de interacción con la gestión gubernamental.
Novel-Fl Operators Based Visibility Processing Techniques of Denoising Algorithm Using Exdark Dataset Simulation
Authors: Saikiran Palla , Kumar Pattem Sampath
Published: February 2024

Abstract: An inclement dusty weather can significantly reduce the visual quality of captured images and this consequently leads to hamper the observation of meaningful image details. Capturing images in such weather often leads to undesirable artifacts such as poor contrast, deficient colors or color cast. Hence, various methods have been proposed to process such unwanted event and recover vivid results with acceptable colors. These methods vary from simple to complex due to the variation of the used processing concepts. In this article, an innovative technique that utilizes tuned fuzzy intensification operators is introduced to expeditiously process poor quality images captured in an inclement dusty weather. Intensive experiments were carried out to check the processing ability of the proposed technique, wherein the obtained results exhibited its competence in filtering various degraded images. Specifically, it performed well in providing acceptable colors and unveiling fine details for the processed images. This study expanded upon earlier methods of low-light picture enhancement that relied on DCP. After the light reflection direction was initialised, it was refocused using the red channel estimate. Separating the region with strong lighting characteristics from the background darkness zone is another usage of DCP. The next step was to create and assess new anthropogenic light quality by estimating and refining transmission maps. An image free of black areas is also produced by recovering the picture light radiance using the updated transmission map data. The last step in achieving high-quality output images is using the denoising algorithm. Results from the ExDark dataset simulations shown that the proposed strategy achieved better subjective and objective performance than state-of-the-art methods.
Derechos humanos, derecho animal y crítica de la violencia especista
Authors: Ávila Gaitán Iván Darío
Published: February 2024

El propósito de este artículo es abordar la cuestión del vínculo contemporáneo entre el derecho animal, los derechos humanos y la crítica de la violencia especista. Se argumenta que dicho vínculo se encuentra en la sintiencia, la cual ha sido reconceptualizada como la capacidad de experiencia subjetiva o consciencia, en contraste con la tradición aristotélica y cartesiana. En estas tradiciones, respecto a los animales, la sintiencia a veces se percibe de manera esencialista para legitimar una supuesta inferioridad natural y la consecuente explotación, mientras que otras veces se considera de manera reaccional descualificada. Esto contrasta con la sintiencia cualificada, que está asociada a un yo humano reflexivo. Con la reconceptualización contemporánea de la sintiencia, se argumenta que esta no necesita de un yo reflexivo cartesiano-kantiano, pero sí implica un modo de individuación a partir del cual existe alguien que puede ser afectado, que valore su vida y que distinga sus experiencias de las de los demás. En ese sentido específico, la sintiencia es sinónimo de consciencia. Este enfoque proporciona una base común para los derechos humanos y el derecho animal, ya que solo los seres que experimentan la vida como propia tienen derecho a la vida, la libertad y la integridad corporal. Esto, a su vez, lleva a cuestionar el estatus actual de los animales como cosas, bienes, recursos o propiedad. El artículo concluye estableciendo un vínculo entre la crítica de ese estatus y la crítica de la violencia especista. Esta violencia se fundamenta en el establecimiento de fronteras que separan el ego humano del Otro animal, relegado a la condición de cosa, bien o posesión. Según este argumento, en la línea de la filosofía jainista, se hace evidente que la construcción de culturas de paz requiere el reconocimiento tanto de los derechos básicos para los animales como de la codependencia interespecífica entre humanos y (otros) animales.
Derechos para todos los animales
Authors: De la Torre Torres Rosa María
Published: February 2024

Los sistemas jurídicos occidentales, herederos de las tradiciones romanistas o germánicas, consideran a los demás animales como cosas, como objetos de propiedad que pueden instrumentalizarse y disponerse en beneficio de los seres humanos sin ningún límite. La crueldad con la que son tratados los animales explotados para el consumo humano, ya sea como alimentos, para entretenimiento o con fines científicos es una constante en la historia de la humanidad. A pesar de que se han construido normas para intentar procurar el bienestar de los animales en los procesos de explotación esto no ha servido sino para normalizar su instrumentalización. Es preciso deconstruir los paradigmas que desde el derecho se han construido y recordar que todos somos animales, que las diferencias físicas o cognitivas no justifican la exclusión de ningún ser sintiente de la esfera moral y jurídica. Se debe construir un nuevo lenguaje jurídico porque todos somos animales.
Errantes, asilvestrados, familiares, racializados, cosas… categorizaciones jurídico-políticas de los ladradores
Authors: Aboglio Ana
Published: February 2024

Este artículo analiza las relaciones constituidas con las llamadas especies compañeras, particularmente con los perros, examinándolas desde perspectivas interrelacionadas, se los defina como errantes, refugiados, asilvestrados, racializados, cosas-objetos, experimentales o integrantes de un ámbito familiar. Se desplegará una cartografía rizomática desde los estudios críticos animales, que revelará cómo las desigualdades categoriales organizan un biopoder que transita entre conflictos de intereses habitualmente resueltos en clave antropoespecista y en tensión con las reivindicaciones de derechos para los animales. Mientras que los perros están adquiriendo mayor consideración moral y jurídica, el escenario general donde se los aloja no parece tan promisorio. El interrogante es ¿cómo impactan estos cambios en todos los perros y demás animales explotados y su participación en una reconfiguración de la máquina antropológica? Para esto, también se examinan cuestiones éticas ligadas a la posesión de animales compañeros y se traza una genealogía de la trayectoria del perro en la sociedad occidental, que facilitará una mejor comprensión del presente. La introducción sintetiza el estado actual de la cuestión animal en el ámbito jurídico, ético y político, exponiendo esa íntima fusión de abordajes que la alcanza y enmarcando así el contenido específico abordado. Los apartados siguientes consideran los principales conjuntos en los que son introducidos los perros por los cruces jurídicos y sociales que los atraviesan, revelando las narrativas que organizan diversos discursos para construirlos de una determinada manera. En el apartado final se reflexiona acerca de la compleja situación de los que suelen no tener permiso para ladrar.

Published: February 2024

El presente texto se desarrolla en dos partes. En primer lugar, se justifica la idea de que los animales no humanos puedan ser susceptibles de asignación de derechos desde una perspectiva deontológica. En segundo lugar, se describen las principales tipologías de conflictividad en la relación humano-animal en Bogotá, junto con las herramientas jurídicas para afrontar estos conflictos y las acciones complementarias de acción integral como resultado del trabajo de recolección de datos del Centro de Atención Jurídica del Instituto Distrital de Protección y Bienestar Animal de Bogotá. Este análisis se basa en un marco de derecho animal no antropocéntrico con bases filosóficas.
Políticas afectivas y colectividad animal
Authors: Davidson Martina
Published: February 2024

Desde hace algunos años, muches investigadores se dedican a estudiar la animalidad y sus múltiples brazos extendidos hacia la ética, la política y los derechos de otras especies más que humanas. Existen varias justificativas para elegir desarrollar investigaciones más animales, pero este artículo destaca el hecho de que pensar en la animalidad y desde ella puede proporcionarnos caminos filosóficos alternativos a los pensamientos antropocéntricos y coloniales, de modo que se visibilicen o construyan mundos otros, mundos multiespecie. Para comenzar a reflexionar sobre estos mundos, en un primer momento se desarrolla la noción de mundos multiespecie. Luego, se presenta la noción de política afectiva animal (y colectividad animal), ejemplificada a partir de arañas y lobos. En seguida, partiendo de esas reflexiones y aportes teóricos, este artículo sostiene que las políticas afectivas animales y las experiencias colectivas animales (y el afecto en todo su alcance) se entienden como una de las múltiples herramientas posibles para (re)producir mundos multiespecie. A través de este recorrido, se abre la posibilidad de explorar vías para investigar los afectos y sus políticas en la animalidad, como una alternativa potente para ampliar aún más nuestra capacidad de negociación en el terreno incierto de los mundos multiespecie. Investigar la inversión afectiva que atraviesa los meollos de las disputas sobre el significado de las relaciones y del mundo, nos reubica en el debate y valora la condición conflictiva inherente a la toma de decisiones más justas en el ámbito de la ética y política.
Flawed Emergency Intervention: Slow Ocean Response to Abrupt Stratospheric Aerosol Injection
Authors: Pflüger Daniel , Wieners Claudia Elisabeth , Kampenhout Leo van , Wijngaard René , Dijkstra Henk A.
Published: February 2024

Given the possibility of irreversible, anthropogenic changes in the
climate system, technologies such as solar radiation management (SRM)
are sometimes framed as possible emergency interventions. However,
little knowledge exists on the efficacy of such  deployments. To fill in
this gap, we perform Community Earth System Model 2 (CESM 2) simulations
of an intense warming scenario on which we impose gradual early-century
SRM or rapid late-century cooling (an emergency intervention), both
realised via stratospheric aerosol injection (SAI). While both scenarios
cool Earth’s surface, ocean responses differ drastically. Rapid cooling
fails to release deep ocean heat content or restore an ailing North
Atlantic deep convection but partially stabilizes the Atlantic
meridional overturning circulation. In contrast, the early intervention
effectively mitigates changes in all of these features. Our results
suggest that slow ocean timescales impair the efficacy of some SAI
emergency interventions.

Published: February 2024

Introduction/Objective. The goal of our research was to evaluate diagnostic and prognostic role of positron emission tomography/computed tomography (PET-CT) in patients previously treated for uterine cancer and compare it to conventional imaging methods (CIM). Methods. We analyzed 37 patients examined on PET-CT for follow-up or suspicion of uterine cancer recurrence, and who were previously treated with surgery and/or chemoradiotherapy. All patients underwent CT or magnetic resonance imaging prior to PET-CT, and were followed-up for at least one year. Results. PET-CT showed sensitivity, specificity and diagnostic accuracy in uterine cancer relapse detection of 96.3%, 70%, and 89.2%, while those values for CIM were 92.6%, 40%, and 78.4 %, respectively. Correlation of PET-CT and CIM findings was 78% (29/37). In 13 out of 25 true positive patients on CIM, PET-CT found greater number of active sites missed by conventional imaging. Positive findings on PET-CT were associated with shorter progression free survival (p = 0.023, logrank test). Conclusion. PET-CT constitutes an important diagnostic method in management of recurrent cancer of uterine corpus, demonstrating high sensitivity and accuracy. In comparison to CIM, PET-CT can discover larger number of active tumor sites, and also shows better specificity. PET-CT positive patients have worse prognosis with shorter progression free survival.
Simulation of the joint operation of an electric motor and a hydraulic coupling in a belt conveyor drive
Authors: Goncharov Kirill , Lagerev Alexander
Published: February 2024

The task of ensuring smooth movement of the conveyor belt during the
operation of powerful belt conveyors with a long route and several
intermediate electric drives is an urgent technical problem. One of the
effective ways to solve this problem is to create drives that ensure the
joint operation of an electric motor and a hydraulic coupling. In this
article, a mathematical model of the joint operation of an electric motor
and a hydraulic coupling is proposed. When constructing the mechanical
characteristics of their joint work, possible deviations of the electric
motor slip from the nominal values are taken into account. To simulate
various possible approximating functions that describe the mechanical
characteristics of the drive, two of the most accurate mathematical
expressions that are used are the Kloss equation and the equation for
interpolating hyperbolic functions. With regard to the electric drive of a
powerful belt conveyor, the analysis of the appropriate areas of application
of these dependencies is carried out, their main advantages and
disadvantages are considered.
A new high step-up active clamp DC-DC converter with high efficiency
Authors: Vesali Mahmood
Published: February 2024

In this paper, a new high step-up converter with a simple structure is
presented. The auxiliary circuit of the proposed converter is in the form of
active clamp, which provides soft switching condition under zero voltage for
the main and auxiliary switches, hence the converter has high efficiency.
Since the auxiliary switch added in the converter works as an active clamp
and has a complementary command with the main switch, the proposed converter
is not complicated in terms of the control circuit and does not need to
design a new control circuit. This converter has a high voltage gain that
provides a high output voltage with a lower duty cycle, so it is suitable
for a new energy production system such as a solar system. The proposed
converter has been fully analyzed and in order to prove the theoretical
analysis, an experimental prototype has been implemented and tested at a
power of 500 W, which in this power an efficiency of about 97.3% has been
obtained.

Published: February 2024

Mühimmatlar, raf ömürlerinin dolması, depolama veya kullanım esnasında uygun olmayan koşullarda muhafaza edilmesi sebebiyle kullanım dışı kalmaktadır. Bu çalışmada, askeri mühimmatlarda ana imla maddesi olarak en fazla kullanılan ve 2, 4, 6-trinitrotoluen (TNT), heksahidro-1, 3, 5-trinitro-1, 3, 5-triazin (RDX) karışımı olan atık Komposizyon-B (Comp-B) patlayıcısından RDX’in geri kazanımı ve saflaştırılması amaçlanmıştır. Atık Comp-B numuneleri mühimmattan iki farklı yol ile elde edilmiş ve farklı RDX geri kazanım yüzdelerine ve saflığına ulaşılmıştır. Comp-B hem mekanik yolla direk mühimmat bünyesinden, hem de mühimmatın ana dolgusunu sıcak su ve buhar yöntemi ile eriterek geri dönüşüm prosesinden elde edilmiştir. Her iki yöntem ile alınan numunelerden TNT ve RDX’in toluen içerisindeki çözünürlük farklılıklarından yararlanılarak TNT uzaklaştırılmış ve RDX elde edilmiştir (rRDX).

Authors: Maramba Aaron
Published: February 2024

Objectives: To evaluate the correlation between clinical suspicion and the final laboratory diagnosis after the bone marrow examination Design: A 6year retrospective cross-sectional study Setting: Parirenyatwa Group of Hospitals, Zimbabwe Subjects: Seventy-six pediatric bone marrow aspirate (BMA) examination cases from 2016 to 2022 that had data that suited the study available were included in the study. Results: The 76 case participants had median age of 7 (age range 1-12). Six-two (81.6%) cases were found to have a complete BMA examination report while fourteen (18.4%) cases had technical errors reported and therefore excluded from the analysis of case results. Amongst the 14 excluded cases; 10(71.4%) were reported as unsuitable for diagnosis and 4(28.6%) reported as haemodilute for diagnosis. The triggers for BMA examination were grouped as; aplastic anaemia 5(6.6%), anaemia with variations 21(27.6%), pancytopenia 14(18.4%), and suspected haematological malignancies 36(47.4%). Analysis of the complete 62 case reports found; 34(54.8%) haematological malignancies, 2(3.2%) no diagnostic features, 5(8.1%) aplastic anaemia, 17(27.4%) no evidence of neoplasm/ infiltration, 3(4.8%) bone marrow hypoplasia, and 1(1.6%) non haematological metastasis. The percentage diagnostic yield between triggers for BMA examination and the BMA examination reports was 62/76 (81.6%0. However, there was no statistically significant correlation (p=0.275) to conclude that there is concordance between triggers for BMA examination and BMA examination diagnosis. Conclusion: Haematological malignancies were the commonest triggers for BMA examination in this study. Haematological malignancies were also found to be the commonest outcome in BMA reports done in pediatric patients with the major form being all.

The future of agriculture and agricultural policy: perceptions of non-farmers and farmers
Authors: Tienhaara Annika , Niemi Jyrki , Vainio Annukka , Pouta Eija
Published: February 2024

We examined the views of Finnish non-farmers and farmers on the desirable future developments of agriculture and agricultural policy using principal component and cluster analysis by focusing on three key themes: the structure of agricultural production, agri-environmental issues, and the funding of agriculture. There is strong public support for maintaining the viability of domestic agriculture through government intervention, but views differ on allocation of agricultural support and how agricultural production should be developed. A significant number of respondents supported the idea that climate and other environmental issues should be better considered in agricultural policy. However, about half of the respondents accepted environmental damage caused by agriculture and one-fifth perceived the importance of agriculture in a society as declining. These views, not prominent in the public debate, emphasize the importance of regular investigation of citizen opinions for including all the relevant stands in policy discussion to design legitimate policy measures.
Analysis of Product Defect to Reduce Return Product in Flexographic Printing

Product return in 2021 at PT XY increased, but the quality control implemented has not been running effectively. This study aims to analyze the failure risk that causes defects, gets the greatest failure risk in the Risk Priority Number (RPN),and gives suggestions for improvement for the next production. The focus of this study is on production defects that are returned by customers. This study used Failure Mode Effect Analysis (FMEA) methods and Problem Identification Corrective Action (PICA) table. From the gathered data, it is identified that there is one type of dominant defect that is outside the control limits. The results of data processing by multiplying the SOD value to get the RPN value found that the three largest ranking modes of failure were the engine settings did not match the RPN value of 484, negligent in the production control process with the RPN value is 230, and the compressor is not optimal with the RPN value is 210. Then an analysis was carried out using the PICA table to get suggestions for improvements, conducting periodic IK retraining, checking machine condition regularly, conducting periodic inspections during the production process, evaluating performance results, and running check sheets while carrying out the production process.
Starting and Specialisation Ages of Elite Athletes across Olympic Sports: An International Cross-sectional Study
Authors: De Bosscher Veerle , Descheemaeker Kari , Shibli Simon
Published: February 2024

Talent development models are the frameworks that guide sports stakeholders in developing potential athletes, within which early specialisation and diversification remain contradictory strategies. This paper presents new insights into the starting and specialisation ages of world-class athletes in various Olympic sports. A total of 2,838 athletes from 13 nations and 44 Olympic sports were included in this study. The results show that world-class athletes started with their current sport at the age of 10.6 (±5.3) and decided to focus on this sport at the age of 15.6 (±5.0), with obvious variations in these ages across different sports. The study showed a moderate relationship between athletes’ starting and specialisation ages (r = 0.639), which demonstrates the variable duration of the multiple sport sampling period. This period, during which athletes pursue a variety of sports, lasts 4.9 years on average. There is a high degree of variation among different athletes in starting and specialisation ages, even within the same sport. All sports in the study can be classified into five categories based on a combination of their starting ages (early/intermediate/late) and specialisation ages (early/intermediate/late). The Developmental Model of Sports Participation provides the age guidelines for the categories. The five categories contain (I) early specialisation sports, (II) intermediate starting and specialisation sports, (III) late specialisation sports, (IV) late starting sports, and (V) late starting and late specialisation sports. The study concludes by proposing that there is a need for sport-specific talent development models with increased attention to each sport’s starting age, sampling period, and specialisation age.
