Herlyn-Werner-Wunderlich syndrome (HWWS), also known as OHVIRA syndrome (obstructed hemivagina and ipsilateral renal anomaly) is a complex congenital malformation characterized by a triad including uterine didelphys, hemivaginal obstruction, and ipsilateral renal agenesis. In this case report, we present a case of HWWS along with the challenges in diagnosis and multi-step treatment processes. A 25-year-old woman presented to Dr. Zainoel Abidin Hospital in Banda Aceh, Indonesia with a chief complaint of lower back pain for the past six months (two months after the marriage). The patient also complained of late menstruation, followed by thick yellow vaginal discharge resembling malodorous pus occurring after menstruation. Additionally, a history of fever and pain during intercourse was reported. Vaginal examination revealed purulent fluid emerging from a pinpoint hole on the right vaginal wall. Vaginal palpation revealed a two-branched uterus, along with a palpable cystic mass on the right vaginal wall. Ultrasound examination indicated the presence of the right and left hemi-uteri, measuring 4.7x1.35 cm and 5.7x1.26 cm in size, respectively with both ovaries appearing normal. Fluid accumulation was observed in the right hemivagina, while the left kidney exhibited normal features, and the right kidney showed signs of hypoplasia. The patient was diagnosed with uterus didelphys, fluid accumulation in the hemivagina, and right kidney hypoplasia. Magnetic resonance imaging (MRI) confirmed uterus didelphys and revealed narrowing of the right hemivagina, suggestive of HWWS. Hysteroscopy was performed to resect the vaginal septum with laparoscopic guidance, along with drainage of hematocolpos, pyocolpos and placement of an intracervical mold. Despite HWWs having conservative gradual management, it was opted to perform vaginal septum resection, hematocolpos and pyocolpos drainage and placement of an intracervical mould in this case, in order to relieve symptoms and restore the reproductive and sexual functions.
INVESTIGATING ENGLISH LANGUAGE READING AND WRITING ANXIETY AMONG PAKISTANI UNIVERSITY STUDENTS: A CORRELATIONAL STUDY
Authors: Ms. Zahra Khan Mr. Jehanzeb Khan, Dr. Muhammad Fareed,
Published: August 2023

The undertaken study investigated the correlation between English language reading anxiety and English language writing anxiety. A survey research design was employed, and a sample of 298 BBA students from a private university in Karachi was utilized. The students completed two anxiety-measuring questionnaires: The Foreign Language Reading Anxiety Scale (FLRAS) and the Second Language Writing Anxiety Inventory (SLWAI). Descriptive statistics revealed that the majority of students experienced moderate to high levels of English language reading and writing anxiety. Pearson Product-Moment correlation analysis indicated a strong positive correlation between English language reading anxiety and writing anxiety. This means that students with high levels of reading anxiety were likely to also experience high levels of writing anxiety and vice versa. These findings suggest that teachers should not teach reading or writing in isolation. Instead, they should focus on reducing anxiety levels in reading and writing classrooms. Curriculum developers should also consider incorporating strategies for reducing anxiety into their programs.

Published: August 2023

This article presents research on sanitary and bacteriological evaluation of the quality of semi-finished chicken meat and whole chicken carcasses sold in Kostanay. The quality of products was evaluated by organoleptic, biochemical and bacteriological indicators. A total of 32 samples were analyzed, including whole chicken carcasses of domestic poultry and industrial chicken carcasses, as well as semi-finished chicken products (shank, thigh, wings on a substrate). During organoleptic and biochemical analysis of the quality of the samples 5 samples did not meet the requirements of normative documents. Sanitary and bacteriological examination showed excess of total microbial contamination. In a sample of imported semi-finished products the presence of Bacteroidetes was detected. Salmonella and L. monocytogenes bacteria were identified in two samples of domestic chicken. In order to facilitate faster identification of pathogens in food, chromogenic selective media were used, which have a high sensitivity and facilitate their identification. Due to the presence of markers of specific enzymatic activity, the colonies of the bacteria in question are stained with a characteristic colour and the growth of extraneous microflora is inhibited. The use of modern nutrient media saves time for routine laboratory tests.

Published: August 2023

Due to the vulnerability of deep neural networks to adversarial attacks, adversarial robustness has grown to be a crucial problem in deep learning. Recent research has demonstrated that even small perturbations to the input data can have a large impact on the model’s output, exposing them susceptible to malicious attacks. In this work, we propose Delta Data Augmentation (DDA), a data augmentation method for enhancing transfer robustness by sampling extracted perturbations from trained models against adversarial attacks. The main idea of our work is to generate adversarial perturbations and to apply them to downstream datasets in a data augmentation fashion. Here we demonstrate, through extensive experimentation the advantages of our data augmentation method over the current State-of-the-Art in Fast Gradient Sign Method (FGSM) and Projected Gradient Descent (PGD) attacks for CIFAR10 dataset.
The Role of Online Communication Platforms in Maintaining Social Connectedness When Face-to-face Communication is Restricted
Authors: YENİLMEZ KAÇAR Gülnur
Published: August 2023

Social connectedness, an indicator of psychological well-being, requires social interaction and communication among individuals. Prior research usually examined the relationship between the use of online communication channels and the sense of social connectedness under the circumstances where face-to-face communication was readily available. Pandemic provided an excellent setting to study the sole effect of the use of online communication on social connectedness as online communication was not accompanied by in-person communication due to restrictions such as lockdowns. Seizing the opportunity, this study aims at investigating the relationship between the use of online communication platforms and social connectedness at a time when face-to-face communication was not an option and individuals employed online communication channels heavily. To this end, a survey was conducted online on 406 college students in Turkey in November- December 2022 to present retrospective analyses. The findings indicate while face-to-face communication is the prime component to build social connectedness, the use of online communication channels, particularly WhatsApp, social networking sites, video call helped to maintain social bonds among individuals when in-person communication was virtually absent. The research provides insights on how different communication channels can promote social connectedness with varying degrees depending on their social presence.
El fantasma de la piratería: las vías ilegales de acceso a la literatura científica en el CONICET (Argentina)
Authors: Zukerfeld Mariano , Liaudat Santiago , Terlizzi María Sol , Monti Carolina , Unzurrunzaga Carolina
Published: August 2023

Este artículo presenta los resultados de una encuesta realizada a investigadores e investigadoras de Argentina sobre los distintos tipos de acceso a la literatura científica, las motivaciones de uso de la vía ilegal, las representaciones sobre legalidad y corrección moral en el acceso a artículos científicos y el vínculo entre productividad y vías de acceso. Ofrece evidencia empírica de un uso masivo y extendido del acceso ilegal a literatura científica entre los y las encuestadas. Entre los hallazgos más notables destaca, por un lado, que el uso de la modalidad ilegal de acceso no suplanta, sino que coexiste con la utilización de las vías legales. Por otro lado, existe un marcado desacople entre las representaciones en torno a la legalidad y la corrección respecto al acceso y difusión de literatura científica protegida por derechos de autor. En tercer lugar, las motivaciones que explican el uso masivo de las vías ilegales combinan aspectos prácticos y valorativos como la imposibilidad de acceder de otra forma, la facilidad de uso frente a los servicios legales y el rechazo al negocio editorial en torno a la literatura científica.
Ciencia, tecnología y discapacidad: apuntes para pensar la discapacidad desde la teoría del actor-red y el enfoque semiótico material
Authors: Soto Mauro
Published: August 2023

Desde el modelo social anglosajón, la discapacidad se define como una construcción social y política que excluye a aquellos sujetos que poseen una corporalidad con deficiencias. Es decir, la discapacidad no partiría de un cuerpo con ciertas características, sino de determinadas condiciones sociales que limitan o restringen la participación de dichos sujetos. Si bien el mencionado modelo permitió contestar a las visiones más tradicionales sobre la discapacidad -aquellas que la definen como enfermedad, pecado o tragedia personal-, este presenta algunos límites: la expulsión de las nociones de cuerpo y experiencia en la comprensión de la discapacidad; una concepción de esta como un fenómeno homogéneo y mecanicista; un sostenimiento en los esencialismos modernos y antagónicos de cuerpo/mente, naturaleza/cultura, subjetivo/objetivo, micro/macro, experiencia/sociedad. A los fines de abordar estas limitaciones, el presente trabajo retoma los aportes del campo CTS, específicamente de la teoría del actor-red y el enfoque semiótico material. Asimismo, se trabaja esta perspectiva desde un caso concreto de acceso y uso de tecnologías digitales por parte de una persona con discapacidad visual.
Plant Variety Rights in New Zealand: Then and Now
Authors: Bellchambers Helen , Jefferson David
Published: August 2023

This seminar will discuss the changes adopted in the recent overhaul of the plant variety rights system and how they may operate once the law is fully implemented. In addition to discussing the likely impact of the new Act on plant breeding and the New Zealand economy, the seminar will consider the Act’s recognition and respect for the Crown’s obligations under the principles of Te Tiriti o Waitangi | the Treaty of Waitangi, particularly in relation to the realisation of tino rangatiratanga. The discussion is based on recent research involving both doctrinal analysis of the PVR Act and an intellectual property landscape analysis. This latter methodology reveals how plant variety rights systems, both within Aotearoa and overseas, have been used by entities without Māori ancestry to assert ownership claims to varieties of taonga plants in the past. The seminar will explore how some of the changes made in the PVR Act support the exercise of partial Māori authority in relation to taonga, and the limitations on realising tino rangatiratanga via the New Zealand plant variety rights system.

Del flâneur, pasando por la flâneuse a la callejera
Authors: Bustos Garduño María
Published: August 2023

Visitar las imágenes del flâneur, la flâneuse, para luego recrear a la callejera resulta útil metodológicamente a efecto de dilucidar el modelo separatista público-privado de los espacios y las consecuentes asignaciones en-generizadas de los cuerpos realizadas en ellos. Especialmente la primera figura expresa el privilegio masculino no solo del estar, sino del potencial de construir reflexividad sobre lo urbano desde el deleite corporal andariego. En tanto la segunda siendo ficcional, intenta oponerse a tal prerrogativa e incluir a las mujeres. Empero, la callejera desde lo injurioso, abyecto y la imaginación política, resulta ser el símbolo realmente capaz de reclamar el derecho de los cuerpos femeninos a aparecer en el espacio público, sin enfrentarse al miedo, las agresiones y la violencia feminicida. Por el contrario, hacerlo desde el gozo corporal, la complicidad entre mujeres, la adquisición de saberes y la resistencia política. De ahí su potencialidad como categoría teórica feminista-decolonial. Más aún, dada la hapticidad del ícono, cualidad contentiva en la práctica por antonomasia realizada por la callejera, el andar placentero por las calles, un caminar incluso místico y erotizante; hacia el final del artículo expongo el método de reconocimiento urbano por mí, diseñado e inspirado en dicha imagen: las An-danzas.
Superficies de las imágenes
Authors: Culp-Morando Edwin , Bermúdez Dini Renato
Published: August 2023

La disputa por las imágenes y la imaginación es uno de los terrenos más vitales en los que se juegan las prácticas de la resistencia política en la actualidad. Los violentos escenarios de precarización y extractivismo de la vida empobrecen la experiencia y dificultan su recuento y visibilización. Las imágenes parecen condenadas a estar al servicio del espectáculo mediático, a mostrar la victimización o a inundar el espacio visual de evidencias inconsecuentes. Sin embargo, lejos de renunciar a las imágenes por su superficialidad, las prácticas críticas pueden dar cuenta de ellas a través de las tensiones de sus superficies: de las apariencias y el aparecer, de la desaparición, de la conformación de evidencias, de la afectación, de la resonancia, de la fricción. El problema no es tanto que sobren imágenes, sino más bien que se ha debilitado la capacidad de imaginar (Bottici, 2018).

Authors: Bulagi Mushoni , Lebepe Tshepo Maxwell , Hlongwane Jan Johannes
Published: August 2023

The purpose of the study was to analyse the determinants of South African citrus exports post era of trade liberalisations using secondary data from 1996 to 2018. The Johansen Cointegration model was used to test the long-run relationship between the citrus export and the determinants in the post era of trade liberalisation and Ordinary Least Squares regression was used to determine the relationship between citrus export in South Africa and the selected determinants post the era of trade liberalisation. The results of the Johansen Cointegration model show the existence of a long-run equilibrium relationship between citrus exports and the determinants of South African citrus exports. The Ordinary Least Squares regression results provided evidence that citrus production and citrus world market prices are the major influencers of citrus export in South Africa. The Department of Agriculture and the Citrus Associations should make initiatives to ensure an increase in citrus production by promoting development programmes for the citrus producers.
Modeling Footprint Profiles for Different Drop-Substrate Pairs
Authors: Mahrous Elaf N
Published: August 2023

Modeling drop dynamics in 3D is an active area of research. Of particular interest is the simulation of the contact line profiles for moving liquid drops of varying physical properties, such as liquid surface tension and substrate wettability. The Lagrangian Particle Finite Element Method (PFEM) numerical approach is adopted for predicting the footprint profiles of moving liquid drops. The Lagrangian PFEM is advantageous due to its ability to provide an accurate mesh-based boundary description, and thus, facilitates the computation of the freesurface and footprint evolution. The modeling outcomes agree with the general experimental behavior for different dropsubstrate pairs with widely differing properties.
Plastic Deformation Analysis of a Heat Treated Vibrating Screen Bracket
Authors: Sekwai Mathapelo , Madyira Daniel M. , Oosthuizen Gert A.
Published: August 2023

Vibrating screens have significantly improved the particle separation process in the mining industry. However, they operate under demanding conditions. Components such as the cross bracket, used to transmit the excitation from the actuation motors to the screen frame, are prone to failure. To improve the welded joints, a newly developed vibrating screen mounting bracket was heat-treated in the oven at 580˚C to relieve the residual stresses in the weld. The air that was trapped inside the interior of the vibrating screen bracket expanded due to the heating and this cased the permanent deformation. This necessitated detailed analysis of the behavior of the bracket under elevated temperature conditions to mitigate the permanent deformations while maintaining expected performance dictated structural integrity. This work aimed to determine the load that caused the permanent deformation of the vibrating screen mounting bracket using experimental, analytical, and numerical methods. The pressure that caused the permanent deformation was determined to be 0.510 MPa and 0.6235 MPa analytically and numerically respectively. This showed a percentage difference of approximately 18%. The solution for avoiding the expansion of the vibrating screen mounting bracket was to introduce holes onto the structure of the vibrating screen so that no air would be trapped inside the bracket.
Plasticity Deformation Displacement Models for Metal Plates-A Review
Authors: Sekwai Mathapelo , Madyira Daniel M. , Oosthuizen Gert A.
Published: August 2023

This paper presents a review of existing plastic deformation displacement analysis models for materials and components. Plastic deformation analysis is important in the study of failed components. This is because it provides insight on how materials and components behave after the yield point has been exceeded and the deviation of the plates from their original position in terms of displacement. The plasticity phenomenon also provides insight on how to improve the engineering materials and components to avoid their failure and to decide if the displacement of the plate is significant enough to discard the plate or it is still within operating standards. There are multiple analytical models that offer a method of predicting plastic deformation displacement. These are divided into the material and component (plates) plasticity models. The different plasticity models will be presented, with their limitations being highlighted. In recent years the more commonly used methods are numerical and experimental, however the analytical models are still useful for initial plastic deformation predictions. The plasticity models reviewed in this paper are a combination of either one of the aforementioned models.

Authors: Azzam Mohammed , Hamdan Mohammad O. , Alkhader Maen , Gerner Frank
Published: August 2023

In this study, we numerically investigated the heat removal effectiveness of various phase change materials (PCMs) when injected into a plate-fin heatsink with a fixed thermal conductivity enhancer (TCE) volume fraction of 9%. This study focuses on examining the effects of fin numbers and PCM types. The numerical simulation, using ANSYS commercial software, shows that the performance of the PCMinfused heatsink has improved as the number of fins increases. When a plate-fin heatsink soaked in paraffin wax and exposed to a heat-flow density of 4 kW/m2 for 30 minutes, the maximum temperature did not exceed 70°C for the 4-fin design but it exceeded 80°C for the 0- and 2-fin design. The salt hydrate PCM has shown superior performance when compared to paraffin wax and RT35. The zero-fin model has taken double the time required to melt all the PCM when compared to 2- and 4- fin heatsinks.

Control Oriented Model of the Throttle Valve for Pumping Applications
Authors: Gevorkov Levon , Domínguez-García José Luis
Published: August 2023

In pumping plants, oil production, and many other industries, throttle valves play a crucial role. Throttle valves are used to control the liquid flowing through them and they are frequently employed as flow control devices. A proposed throttle control simulation approach for centrifugal pumps is presented. A specific stepper motor-based model is designed to offer various possible simulation scenarios. The stepper motor, control system, gearbox, centrifugal pump, liquid tank, pipeline, throttle valve, and sensors are among the model's essential parts. A number of simulations were done in order to examine the proposed model. The modelling demonstrates that the proposed simulation is quite accurate and simple to modify. The electric drive model that has been developed is suitable for the validation of different operation modes of pumping plants that involve throttling.
An Analysis of the Performance of a Grid- Connected Hybrid Power Generation System Combining Wind and SOFCs, with an Ultracapacitor Storage Unit
Authors: Kumar A. Santhosha , Nuvvula Ramakrishna S S , Koten Hasan , P. Raghavendra , Kumar Polamarasetty P
Published: August 2023

This paper explores the usage of hybrid power generation system based on a Solid Oxide Fuel Cell (SOFC), Wind, and an Ultra-Capacitor (UC) in a grid-connected scheme. The UC acts as an energy storage system to compensate for the slow dynamic response of the SOFC. This combination of components effectively maintains a stable output of power from the Wind system. Control systems are implemented to manage the power converters associated with the energy system to meet the expected demand. The SOFC needs to increase its power in the face of changes in the inverter power or a decrease in Wind power, and in both cases, the UC supplies energy until the SOFC reaches the desired power output level. Recharging of the UC is done using Wind power. The hybrid system is capable of providing constant power irrespective of fluctuations in wind speed. Results obtained from simulations are presented to demonstrate the performance of the hybrid system with respect to the changing wind speed and load.

A REVIEW OF FARMERS-HERDERS CONFLICT AND IMPLICATIONS ON FOOD SECURITY, ECOLOGICAL SYSTEMS AND ECONOMY OF IBARAPA, OYO STATE, NIGERIA
Authors: Ahmed Jimoh Ayinla , Ranti Lawal Amudalat , Adebayo Bello Zakariyau
Published: August 2023

In Nigeria, thousands of people die in violent clashes between groups of farmers and nomadic pastoralists. Due to better access to weapons and communication tools, the war has been worse in recent years. The old and the well-established systems of negotiation between the groups have mostly broken down. Thus, those with superior tools try to acquire what they want without speaking to other parties. The lack of resources, however, did not suddenly appear in the region and is also a result of several other factors that were discussed in this study, such as ineffective state mechanisms, the Nigerian oil boom, late effects of colonialism, climate change, constantly rising non-state group armament, e. t. c. To demonstrate effects of the conflict, the socioeconomic implications will be discussed. This research focuses on the crisis between the farmers and the Fulani herdsmen in the Ibarapa community of Oyo State as a review case study. The Ibarapa community is made up of various socioeconomic groups who have lived together for a long time, even though this coexistence has both beneficial and negative effects. Yoruba people, that are primarily farmers, and Fulani herdsmen, who are primarily herders, make up the majority of those leaving the Ibarapa community. In recent years, tension and hostility between farmers and herdsmen have emerged due to the battle for land and other scarce resources. Insecurity and food crisis have also resulted from the conflict, which have escalated into fights between the two groups. The connection between the two groups has soured, though, and this is a serious matter that warrants attention on a worldwide scale. Hence this review is apt.

Introducción. Gabriel Tarde fue un criminólogo, jurista, sociólogo y psicólogo social de segunda mitad del siglo XIX. Expuso una teoría del progreso y presentó a la innovación como un elemento central. La presente revisión ha colocado su foco en el pensamiento de Tarde sobre el progreso socioeconómico y la innovación. Métodos. Se realizó un análisis bibliográfico de seis de sus obras, que incluyen cinco libros y un ensayo. Se seleccionaron aquellas que presentaron su perspectiva sobre el progreso socioeconómico y su rol en la innovación. Desarrollo. El autor presenta una perspectiva del progreso sustentada en las fuerzas de deseos y creencias del agente social. Colocó especial atención a la característica imitativa de la sociedad, concluyendo que deseos y creencias se expanden por un proceso imitativo. La economía política debería estudiarlos en profundidad. Concebía a la innovación como variaciones que alteraban ese proceso y eran necesarias para el progreso. Según su visión, los países en vías de desarrollo transitaban una fase de surgimiento del deseo de consumo de bienes extranjeros, a la que seguía otra fase de despertar del deseo de invención y producción propia. Conclusión. Una visión heterodoxa fue expuesta sobre la dinámica socioeconómica. La acción de la economía política debe estudiar los deseos y creencias como activadores de consumo, invención y producción, ya que se expanden mediante un proceso imitativo. Tarde consideró que esto tiene implicancias en el progreso de los países en vías de desarrollo.

Contract Law in an Era of Technology: Examining Liability in Smart Contract Transactions
Authors: Edema Tega
Published: August 2023

The growing use of smart contracts in a wide range of transactions has raised a deluge of legal issues, including allocation of liability in such transactions. In many circumstances, using smart contracts involves a range of legal risks that might be distributed beyond the contractual parties to other parties, such as the developers of the smart contract code. While smart contracts have the potential to disrupt the current legal and transactional status quo, notorious occurrences such as attacks on Ethereum or Bitcoin platforms highlight the need to properly dissect the issue of liability and rightly apportion liability where it falls. This also includes working on any lapses in the existing legal and transactional framework to cater for these issues. This article sets out to examine the validity of smart contracts in the light of existing contract law principles. It examined the legal regime and development of smart contracts in Nigeria. It further discussed the problem of allocation of liability associated with smart contracts. It made certain propositions on how these issues could be tackled including the amendment of existing legal framework to aptly provide for and regulate the smart contracts era particularly in Nigeria. The doctrinal method of research was employed to dissect the issues raised and discussed in the article. Relevant texts were scrutinized and analyzed to arrive at the findings and recommendations contained in the article.
Treading a Path for Effective Renewable Energy Regulation in Nigeria: Lessons from Brazil
Authors: Odebala Victor Junior
Published: August 2023

Rising temperatures, rising sea levels, droughts and other climate change induced variants are mounting pressure on national governments to reassess their commitment to global climate change goals and their general approach to energy production and consumption within their territories. Renewable energy has become a recurring theme in the drive towards attaining clean energy and maintaining a sustainable culture. Failing to reconcile with this reality will result in negative environmental, as well as economic consequences on any nation, as less and less investment are being made in conventional energy sources. This paper aims to assess Nigeria’s current attitude to renewable energy development from the perspective of the nation’s regulatory framework. Using a comparative analysis methodology, it finds the presence of an indirect and inefficient regulatory regime on renewable energy in the country. It compares this to Brazil’s regulatory regime where it finds a comprehensible and direct regulatory structure. It asserts that the success of the Brazilian renewable energy integration is attributable to the presence of a detailed energy licensing process, direct legislation, supported research and development scheme and adequate market strategy for renewable energy. Recommendations were made along this line for more efficient renewable energy regulation in Nigeria.

Nature reserves are areas that are protected and managed in order to preserve and maintain the natural environment and promote the survival and diversity of wildlife. Effective management of a nature reserve requires a clear plan that takes into account the characteristics and needs of the area, as well as the external and internal influences that may impact it. This includes gathering information about the plants, animals, and other features of the area and considering the impact of human activities and other external factors. It is also important to carefully consider the ownership and long-term management of the reserve, and involve local authorities and other stakeholders in the management process. Additionally, the reserve may also be used for research and recreation, as long as these activities do not negatively impact the natural environment.

Published: August 2023

International studies indicate that preservice teachers are inadequately prepared to conduct effective family–school partnerships (FSP), and first-year preschool teachers may find working with families especially challenging. This issue calls for more attention in teacher-training programs toward preparing teachers with sufficient competence for FSP. This study is intended to provide knowledge about Swedish preschool student teachers’ perceptions and experiences working with FSP to inform development areas within teacher education. Data were collected using an online survey of 153 preschool student teachers. The results show that most participants have a positive view of FSP based on their knowledge and previous experience. Communication is regarded as the most important prerequisite but also one of the top challenges. However, they estimate their preparedness to work with parents at varying levels and recognize that competence is created and developed through experience and a reflective approach. It calls for more practical training in combination with theoretical knowledge in teacher education to prepare future preschool teachers to work with families effectively.

This research aimed to enhance and optimize the ultrasound-assisted extraction (UAE) of lutein from marigold flowers. The Response Surface Methodology (RSM) was the primary optimization technique. Three key independent variables were considered to determine the best conditions for the highest lutein yield: ultrasonic amplitude, extraction temperature, and extraction time. These variables were systematically varied following the Central Composite Design (CCD). Lutein quantitation was achieved using ultraviolet-visible spectrophotometry analysis. Using both the RSM and CCD frameworks, the study established specific ranges for the operational conditions: 21.6–38.4% for ultrasonic amplitude, 23.18–56.82 °C for extraction temperature and 3.18–36.82 minutes for extraction duration. The study determined the optimal extraction conditions to be 32.76% ultrasonic amplitude, 40.08 °C extraction temperature, and 25.82 minutes of extraction time. Under these optimized conditions, the experimental lutein yield closely matched the yield predicted by the RSM model, thus confirming the model's accuracy. The UAE demonstrated a notably superior lutein yield compared to traditional extraction techniques. The RSM is a robust tool for refining and determining optimal UAE conditions for lutein extraction from marigold flowers. With its efficiency, speed, and eco- friendliness, the optimized UAE technique presents significant potential for widespread industrial use.

Dye-sensitized solar cells (DSSCs) have gained attention recently due to their potential in renewable energy. DSSCs explore natural dyes as an alternative to conventional ruthenium- based dyes. This study chose Ficus benjamina, a plant known for its rich pigment, as the natural dye source. The extraction process involved ethanol, methanol, and double distilled water. Using these solvents, we aimed to determine which solvent would be most effective in extracting the dye and ultimately enhancing the efficiency of the DSSCs. The efficiency (η) clocked in at 0.198%, with an open-circuit voltage (VOC) of 61.6 mV and a short-circuit current (ISC) of 0.424 mA for the F. benjamina dye. When compared to other solvents, methanol stood out distinctly. Specifically, the efficiency of the DSSC prepared with methanol-extracted dye improved by 15.67% when contrasted with the double distilled water and 11.05% when juxtaposed with ethanol. This study used a UV spectrophotometer to investigate the extracted dyes' characteristics. This instrument allowed us to meticulously analyzed the dyes’ absorption properties, providing further insights into their potential applications in DSSCs. Consequently, our research underscores the potential of natural dyes, particularly from F. benjamina, in DSSCs. The study can balance sustainability and efficiency in solar cell technology with the right solvent (methanol).
