Authors: Wubie Alemayehu , Dagne Adamneh , Tesfaye Gashaw , Tesfaye Genanaw , Tadese Dawit Adisu
Published: March 2024

The study was conducted to investigate the breeding season, sex ratio, size at maturation, fecundity and condition factor of African catfish Clarias gariepinus in Lake Koka. A total of 754 fish specimens were collected from October 2020 to August 2021. Total length and weight were measured and sexes were identified and gonad maturity levels were recorded. The sex ratio of African catfish in different size classes was similar to that of a hypothetical 1:1 ratio. The length at first maturity (L50) was 51.8 cm in total length. The mean Fulton’s condition factor of female African catfish ranged from 0.65 ± 0.05 – 0.71 ± 0.14, while the males ranged from 0.62 ± 0.04 – 0.7 ± 0.11. The Fulton’s condition factor was significantly higher in August for females than in the rest of the sampling months. The highest ripe gonads were recorded in the rainy season and the lowest was in the dry season, with the percentage of ripe gonads being 27.5%, while the males showed similarly extended maturity patterns among seasons. Fisheries management for African catfish should therefore take into account the estimated L50 value and the main breeding season to sustain the fishery and benefits the fishermen.

Authors: KIZILGÖL Özlem , ÖNDES Hakan , ULUABA Şule
Published: March 2024

Bireylerin hayatında olumsuz deneyimleri ile oluşan intihar davranışı ve eylemi onların günlük yaşamlarında bu düşünce ile hareket etmesi sonucu oluşmaktadır. İntiharın kelime anlamı, bireyin hayatına son vermesi davranışı olarak açıklanmaktadır. İntiharı tek çıkış yolu olarak gören bireyler bu eyleme yönlenerek hayatına son vermektedir. Literatürde intihar ile ilgili oldukça az çalışma yapılmış olması bu çalışmanın motivasyonunu oluşturmaktadır. Bu bağlamda çalışmada 2000-2019 yılları arasında OECD ülkelerinde kadın ve erkek intihar oranlarını etkileyen ekonomik faktörler incelenmiş, söz konusu faktörler ile intihar oranları arasındaki ilişkiler panel regresyon yöntemi ile tahmin edilmiştir. Ayrıca değişkenler arasındaki nedensellik ilişkileri Dumitrescu & Hurlin (2012) Granger Nedensellik testi ile tespit edilmeye çalışılmıştır. Analiz sonucunda işsizlik oranındaki ve enflasyon oranındaki artışın kadın ve erkek intihar oranlarını arttırdığı, kadınların ve erkeklerin işgücü oranındaki ve GSYİH’daki artışın ise kadın ve erkek intihar oranlarını azalttığı görülmüştür. Nedensellik testinden elde edilen sonuçlara göre kadın intihar oranları ile işsizlik ve GSYİH arasında, erkek intihar oranları ile enflasyon, erkek işgücü ve GSYİH arasında iki yönlü nedensellik ilişkisi varken, kadın intihar oranlarından kadın işgücüne doğru ve işsizlik oranlarından erkek intihar oranlarına doğru tek yönlü bir nedensellik ilişkisi olduğu saptanmıştır. Çalışma sonuçlarının konu ile ilgili ileride yapılacak çalışmalara katkı sağlaması ve politika yapıcılara öneriler sunması beklenmektedir.

Este é um estudo sobre a mediação da cultura no processo de compreensão e interpretação das normas jurídicas na determinação de seu significado e alcance de sua aplicação concreta, com base no estudo da obra Verdade e Método, de Hans-Georg Gadamer, analisa-se o papel da cultura no procedimento hermenêutico jurídico, tanto do ponto de vista do intérprete, quanto do destinatário da norma jurídica, onde o jurista entra no jogo da interpretação da norma, com o conjunto de preconceitos proporcionado pela tradição, tendo um horizonte que deve fundir-se com o horizonte do caso concreto, para produzir simultaneamente uma compreensão e interpretação da norma, que permita resolver o caso concreto, por uma solução interpretativa criativa que se manifesta através da linguagem, que no que lhe concerne é um produto cultural que permite a compreensão e expressão do pensamento humano em diálogo até com outras culturas, para que a cultura seja o palco, o horizonte onde se dá o processo histórico de formação e aplicação do ordenamento jurídico.
Três objeções ao uso de violência em defesa de animais não-humanos e por que elas fracassam
Authors: Garmendia da Trindade Gabriel
Published: March 2024

No presente artigo analisarei as três principais objeções comumente empregadas para rejeitar o uso de violência em defesa de animais não-humanos. Existe a ideia de que a violência é inerentemente errada e sempre deveria ser repudiada – eu chamo isso de ‘Objeção do Pacifista Absoluto’. Há também a perspectiva de que a utilização de violência por ativistas interespécies acaba alienando o grande público do movimento pelos direitos dos animais não-humanos como um todo – eu me refiro a esse argumento como ‘Objeção da Hostilidade Pública’. Por último, encontra-se na literatura dos estudos interespécies o argumento de que lançar mão de violência pró-não-humanos é contraproducente, pois táticas violentas seriam responsáveis pela criação de leis que protegem aqueles que exploram os animais não-humanos e criminalizam as ações de ativistas interespécies – essa é a ‘Objeção do Impacto Contraproducente Visível’. Após apresentar cada uma dessas objeções explicarei por que nenhuma delas é capaz de oferecer um argumento definitivo contra o uso de estratégias violentas em favor dos membros de outras espécies animais sencientes.
Reinterpretando a pólis democrática: a tensão da justiça no inquérito de Édipo
Authors: De Oliveira Morais Ricardo Manoel , Tierno Patricio
Published: March 2024

O objetivo é analisar algumas interpretações conexas que giram em torno da tensão entre duas concepções da díke em Édipo Rei. Como as tragédias ocupavam um papel privilegiado na pólis ateniense, pode-se dizer que as exibições e festividades trágicas eram uma verdadeira instituição política. Não por acaso se pode afirmar que as peças apontavam para um conflito entre os valores aristocráticos tradicionais e a nova ordem democrática. Tal tensão pode ser evidenciada na investigação promovida por Édipo que se manifesta em duas formas de justiça, uma de origem divina e outra, humana. Para tanto, este texto, em um primeiro momento, descreve a relação entre tragédia e pólis; após essa introdução, assinala o conflito que se desenhava na democracia e que se reflete nas tragédias; por fim, examina a possível articulação racional entre a díke tradicional e sua contrapartida humana.
Raízes ultraconservadoras da direita na perspectiva adorniana
Authors: Pereira Mara Cristina
Published: March 2024

Na palestra proferida no ano de 1967, Theodor W. Adorno, um dos grandes pensadores da Escola de Frankfurt, começa ressaltando que não intenciona apresentar uma visão da direita radical na completude que o tema exige, mas sim apontar algumas das características de uma nova direita mais radical do que ele havia abordado em uma palestra no ano de 1959. Dessa forma, frente aos novos elementos socioeconômicos da recente queda do nazifascism, o filósofo alemão considerou necessário abordar novos aspectos do que ele chamou de novo radicalismo de direita.

Published: March 2024

Cultivation of tiger prawns stands as a crucial sector in Indonesia's fisheries industry, significantly contributing to the country's foreign exchange. However, challenges persist in the cultivation process, particularly concerning suboptimal harvest outcomes. A critical factor in tiger prawn cultivation is the water temperature within shrimp ponds, a parameter directly influencing shrimp growth. The recommended normal temperature range is 28-31°C. Deviations from this range can adversely impact the shrimp's metabolic system and appetite, resulting in stress and potential mortality. Temperature fluctuations can lead to severe issues such as hindered growth, reduced productivity, and increased shrimp mortality. Real-time monitoring of air temperature emerges as a pivotal element in ensuring the success of shrimp farming. This research aims to provide a practical solution for shrimp cultivation by presenting a system that enables farmers to adjust air temperature in ponds in real-time through a user-friendly website application. The ability to promptly respond to abnormal temperature fluctuations empowers farmers to optimize cultivation conditions, thereby reducing shrimp mortality rates. The research focuses on creating a water temperature monitoring system for tiger prawn ponds using cloud storage through the Firebase platform. By implementing real-time temperature monitoring, financial risks for shrimp farmers can be mitigated, preventing losses attributed to temperature-induced shrimp mortality. The research utilizes the DS18B20 temperature sensor and WeMos D1 R2 as the control center. The website displays air temperature measurements, showcasing a high accuracy of 99% with a minimal error of 1.2%. This underscores the system's effectiveness in measuring air temperature both above and below the pond. The incorporation of IoT technology for monitoring water quality in ponds offers a practical and innovative approach to tiger prawn cultivation, with the potential to enhance production outcomes in each harvest.
Enhanced Trajectory Tracking of 3D Overhead Crane Using Adaptive Sliding-Mode Control and Particle Swarm Optimization

Published: March 2024

Cranes hold a prominent position as one of the most extensively employed systems across global industries. Given their critical role in various sectors, a comprehensive examination was necessary to enhance their operational efficiency, performance, and facilitate the control of transporting loads. Furthermore, due to the complexities involved in disassembling and reinstalling cranes, as well as the challenges associated with precisely determining system parameters, it became essential to implement adaptive control methods capable of efficiently managing the system with minimal resource requirements. This work proposes a trajectory tracking control using adaptive sliding-mode control (SMC) with particle swarm optimization (PSO) to control the position and rope length of a 3D overhead crane system with unknown parameters. The PSO is mainly used to identify the model and estimate the uncertain parameters. Then, sliding-mode control is adapted using the PSO algorithm to minimize the tracking error and ensure robustness against model uncertainties. A model of the systems is derived assuming changing rope length. The model is nonlinear of second order with five states, three actuated states: position x and y, and rope length l, and two unactuated states, which are the rope angles θx and θy. The system has uncertain parameters, which are the system’s masses Mx, My and Mz, and viscous damping coefficients Dx, Dy and Dy. A simulation study is established to illustrate the influence and robustness of the developed controller and it can enhance the tracking trajectory under different scenarios to test the scheme.
Efficient Path Planning Algorithm for Mobile Robots Performing Floor Cleaning Like Operations
Authors: Nair Vishnu G
Published: March 2024

In this paper, we introduce an efficient path planning algorithm designed for floor cleaning applications, utilizing the concept of Spanning Tree Coverage (STC). We operate under the assumption that the environment, i.e., the floor, is initially unknown to the robot, which also lacks knowledge regarding obstacle positions, except for the workspace boundaries. The robot executes alternating phases of exploration and coverage, leveraging the local map generated during exploration to construct a STC tree, which then guides the subsequent coverage (cleaning) phase. The extent of exploration is determined by the range of the robot's sensors. The path generation algorithms for cleaning fall within the broader category of coverage path planning (CPP) algorithms. A key advantage of this algorithm is that the robot returns to its initial position upon completing the operation, minimizing battery usage since sensors are only active during the exploration phase. We classify the proposed algorithm as an offline-online scheme. To validate the effectiveness and non-repetitive nature of the algorithm, we conducted simulations using VRep/MATLAB environments and implemented real-time experiments using Turtlebot in the ROS-Gazebo environment. The results substantiate the completeness of coverage and underscore the algorithm's significance in applications akin to floor cleaning.
Design and Implementation of Fuzzy Logic for Obstacle Avoidance in Differential Drive Mobile Robot
Authors: Puriyanto Riky Dwi , Mustofa Ahmad Kamal
Published: March 2024

Autonomous mobile robots based on wheel drive are widely used in various applications. The differential drive mobile robot (DDMR) is one type with wheel drive. DDMR uses one actuator to move each wheel on the mobile robot. Autonomous capabilities are needed to avoid obstacles around the DDMR. This paper presents implementing a fuzzy logic algorithm for obstacle avoidance at a low cost (DDMR). The fuzzy logic algorithm input is obtained from three ultrasonic sensors installed in front of the DDMR with an angle difference between the sensors of 45$^0$. Distance information from the ultrasonic sensors is used to regulate the speed of the right and left motors of the DDMR. Based on the test results, the Mamdani inference system using the fuzzy logic algorithm was successfully implemented as an obstacle avoidance algorithm. The speed values of the right and left DDMR wheels produce values according to the rules created in the Mamdani inference system. DDMR managed to pass through a tunnel-shaped environment and reach its goal without hitting any obstacles around it. The average speed produced by DDMR in reaching the goal is 4.91 cm/s.

Published: March 2024

Sperm analysis is an initial step in the examination conducted to identify infertility cases in humans. One aspect of sperm analysis involves observing the movement of spermatozoa and determining whether it is normal or abnormal. Normal spermatozoa movement is characterized by progressive motion at an average speed of 20 µm/second, while abnormal movement includes slow or non-motile spermatozoa. Traditional methods can be employed to assess the normality or abnormality of sperm movement, but they have drawbacks such as time-consuming procedures and diverse results depending on the expertise of the examiner. On the other hand, utilizing Computer-Assisted Sperm Analysis (CASA) equipment provides consistent results, albeit at a relatively high cost. Therefore, this research proposes an alternative method for determining sperm movement abnormalities using the Gaussian Mixture Model (GMM) for background subtraction and a matching-based algorithm to track and analyze the formed trajectories, distinguishing between normal and abnormal sperm movement. Human spermatozoa in real-time are used, and their movements are recorded in video format using a bright field microscope. The testing results for determining sperm movement abnormalities based on the GMM method and matching-based algorithm were successful, particularly in videos recorded at 50 fps recording speed, 20 minutes of liquefaction time, and 40x microscope lens magnification. This condition exhibited the highest average accuracy, with a tracking accuracy of 77.3% and an average accuracy for determining sperm motility abnormalities of 87.7%. Therefore, the combined tracking of sperm movement based on the GMM method and matching-based algorithm can be utilized to identify abnormalities in the movement of human spermatozoa.

Microclimate monitoring in agroforestry is very important to understand the complex interactions between vegetation, soil, and the environment. Microclimate parameters include air and soil temperature, air humidity, soil moisture, and light intensity. This research aims to develop a new microclimate data recording system for coffee-pine agroforestry, utilizing LoRaWAN and IoT technology to capture real-time microclimate parameters. Unlike traditional data loggers that require manual download on-site, this innovative system enables instant data download from IoT servers, thereby increasing data efficiency and accessibility. The system proved effective, significantly improving the precision of air temperature and humidity, as well as soil temperature measurements, with an average accuracy of 100%. However, soil moisture and light intensity recorded lower accuracies of 81.23% and 82.56%, respectively, indicating potential areas for future research and system refinement. The system maintains a 15-minute sampling period, aligning with conventional datalogger intervals. This represents an advancement in precision agriculture for microclimate monitoring, enabling the data to be utilized in decision-making for agroforestry management, which involves complex interactions between the local microclimate and the broader ecological system. It underscores the significance of sustainable land use as a response to global climate change.

He had been diagnosed as a plantar wart and treated with chemical destructive methods. Biopsy from the lesion showed infiltrate of nests of atypical melanocytes extending upto reticular dermis. The malignant cells were positive for S100 and human melanin black 45(HMB 45) with a high MiB-1 proliferative index thus confirming diagnosis of amelanotic melanoma (AM). We report this case to highlight the atypical presentation of amelanotic melanoma, the possibility of misdiagnosis and the importance of immunohistochemistry in diagnosing the same.

Natural fibers are becoming a key point for the development of new concrete mixes because these fibers are recovered from residual biomass. In this paper, we focus on the natural fib‘ers found in the Metropolitan District of Quito, Ecuador. For this purpose, we searched for materials (fibers) available in the Chemical Engineering laboratory at Universidad San Francisco de Quito USFQ. In this paper, we analyze different literature on how the use of fibers influences the mechanical properties of concrete. Based on this analysis and the materials at the laboratory, we have developed recommendations on which natural fibers are of interest for further experimental research. Furthermore, this paper provides an understanding of how natural fibers influence the mechanical properties of concrete. It also proposes a process for the selection and study of any type of natural fiber for further replicability in mix analysis.

O kilku zapomnianych pomysłach literackich Karoliny z Hołowniów Swarackiej (1815–1846)
Authors: Berkan-Jabłońska Maria
Published: March 2024

Artykuł omawia tematykę i formę trzech zachowanych powiastek autorstwa zapomnianej literatki doby romantyzmu, Karoliny z Hołowniów Swarackiej. Swój debiut w Wilnie na łamach „Atheneum” w roku 1843 zawdzięczała Józefowi Ignacemu Kraszewskiemu, który uznał jej piśmiennicze próby za warte uwagi. Zmarła przedwcześnie pisarka nie miała jednak szans na pełny rozwój literacki, dlatego jej utwory można traktować bardziej jako zapowiedź talentu niż jego pełnowartościową realizację. Poruszają one jednak sporo interesujących kwestii, które powinno się odnotować w historii literatury kobiecej tej doby. Teatr małego miasteczka oraz Marzenia i rzeczywistość to historie podejmujące problem aspiracji naukowych kobiet, rozwiązywany co prawda przez autorkę po biedermeierowsku, ale też z uwzględnieniem warunków, w jakich przychodziło im określać wzajemne relacje między potrzebami emancypacyjnymi i intelektualnymi a wymaganiami obyczajowymi. Swaracka pokazuje także trudności, jakie bohaterki musiały rozstrzygnąć we własnym myśleniu i psychice, aby zdefiniować na nowo swą tożsamość społeczną i kulturową. W tym kontekście kreacje Alisi i Marii mogą zaskakiwać wieloma bardzo współczesnymi rysami. Również powiastka Nawrócona dotyczy trudnych zagadnień związku szlachcica i Żydówki, odważnie opowiada zarówno o rodzącym się a niepożądanym dla otoczenia uczuciu, jak i sile stereotypów, z jakimi bohaterowie muszą się sami zmagać. Temat podjęty przez Swaracką mógł zainspirować Kraszewskiego do napisania w kilka lat później Powieści bez tytułu.

¿Puede el directorio controlar el deber de Skynet? Repensando el deber de cuidado del directorio en el siglo XXI
Authors: Vizcarra Castillo Raúl
Published: March 2024

En este artículo se explora el deber de cuidado en el contexto del directorio de la empresa, en estrecha relación con la inteligencia artificial. Así, se resalta la ausencia de un sistema de precedentes en la legislación societaria peruana y se aboga por mirar el caso de Delaware, estado que ha establecido criterios sólidos para implementar este deber. De ese modo, se enfatiza la importancia de que el directorio se mantenga informado y establezca mecanismos para supervisar la implementación de la inteligencia artificial, especialmente en el contexto de avance tecnológico en el que nos encontramos.En esa línea, se establecen una serie de recomendaciones como la implementación de mecanismos de control interno y designación de directores especializados. Además, se propone una relectura de ciertos artículos de la Ley General de Sociedades a la luz de esta necesidad de actualización.

Sin dar el brazo a torcer: cláusulas shotgun como mecanismo de solución eficiente ante un bloqueo societario
Authors: Monsante Moy Isabella
Published: March 2024

El bloqueo societario es una situación que no resulta, en lo absoluto, ajena a la realidad societaria peruana. Sin embargo, nuestra legislación societaria actual resulta insuficiente para solucionar esta problemática. Ante ello, en la práctica, los abogados se han visto en la necesidad de buscar soluciones convencionales, importando cláusulas desde el Common Law; a saber, las cláusulas shotgun. El presente artículo tiene como objetivo presentar a las cláusulas shotgun pactadas en el marco de una compraventa de acciones con participación significativa como la solución más eficiente ante un bloqueo societario en sociedades anónimas cerradas y sociedades anónimas con socios paritarios. Se analizarán las posibles soluciones que brindaría la Ley General de Sociedades y se desarrollará la viabilidad de su aplicación en este tipo de situaciones. Se concluirá que el empleo de las cláusulas shotgun pactadas en convenios de accionistas en el marco de una operación de compraventa de acciones con participación significativa resulta ser el mecanismo más eficiente ante un bloqueo societario antes que una posible solución legal.

Finding the Missing Stone: Mobile Money and the Quality of Tax Policy and Administration
Authors: Apeti Ablam Estel , Edoh Eyah Denise
Published: March 2024

Digital financial services like mobile money are increasingly prevalent in developing countries as an alternative to traditional financial services. For many governments, they have become critical components of domestic revenue mobilisation, tax administration modernisation, and broader tax reform. However, making tax administration more efficient and maximising voluntary compliance is a very difficult task. The existing literature on the relationship between mobile money and tax performance in developing countries is limited, although it does show the potential of mobile money to improve tax performance. This paper aims to fill the gap by investigating the relationship between mobile money and the quality of tax policy and administration in developing economies and highlighting some mechanisms underlying these findings, including a lower tax compliance burden, a smaller informal sector, and lower corruption.
Using Digital Technologies to Improve Tax Collection – the Case of Togo
Authors: Kang’oro Dorothy , Ngerero Fidele , Odongo Ignatius
Published: March 2024

The increasing digitalisation of African economies over the past decade, and the spread of mobile money and digital financial services (DFS), present opportunities and challenges to tax administrations in Africa. In principle, the use of digital technologies and expanded use of DFS offer access to new digitised data, increased transparency, and an improved taxpayer experience. However, studies show that tax administrations face important challenges in how best to develop their capacity to use digitised data, and to re-align operations and skills to new digitalised operating models.

Potenziale impatto dello studio REPRIEVE nella gestione clinica della prevenzione delle malattie cardiovascolari nelle persone
Authors: Tommasi et al. Andrea
Published: March 2024

Sebbene la sopravvivenza delle persone che vivono con HIV (PLWH) sia incrementata con l’introduzione della terapia antiretrovirale (ART), il rischio di eventi cardiovascolari rimane un problema di grande rilievo. Mentre sono disponibili dati solidi sull’impiego delle statine nei soggetti con rischio cardiovascolare elevato (CVR), è presente una limitata letteratura in merito ai soggetti con rischio basso-moderato. Lo studio REPRIEVE è andato a valutare i benefici dell’impiego di pitavastatina 4 mg in quest’ultima categoria di pazienti, evidenziando una riduzione significativa degli eventi cardiovascolari nel gruppo di soggetti sottoposti a trattamento rispetto al placebo. La popolazione dello studio appare eterogenea, ma include specificamente pazienti tra 40 e 75 anni. Sono stati arruolati anche pazienti classicamente esclusi dagli studi, quale soggetti con epatite C cronica, utilizzatori di alcol e droghe, persone con patologia psichiatrica. È stato valutato solamente l’impatto della pitavastatina, mentre le altre statine non sono state oggetto di studio. Concludendo, appare auspicabile estendere l’uso delle statine anche nelle PLWH a rischio cardiovascolare basso-moderato, ricordando sempre di ottimizzare anche tutte le altre condizioni che concorrono al rischio.
