Authors: Rosete Fernández Jorge Víctor , Fragoso Islas Abraham , Santos Echeverría Rubén , Ríos Utrera Ángel
Published: January 2024

Introducción. En becerras prepúberes la Kisspeptina-10 ha estimulado la secreción de la hormona luteinizante (LH) y folículo estimulante (FSH), y en vacas posparto amamantando ha estimulado la secreción de LH sin evidencia de inducir la ovulación. Objetivo. Inducir la ovulación con Kisspeptina-10 u hormona liberadora de gonadotropinas (GnRH) en vacas productoras de carne en condiciones subtropicales de México. Materiales y métodos. El estudio se realizó en la región nororiente del estado de Puebla, del 2020 al 2021, con 252 vacas cruzadas Bos taurus x Bos indicus. El protocolo de sincronización estral consistió en la aplicación de un dispositivo intravaginal impregnado con progesterona (1,9 g) y la inyección intramuscular de 2 mg de benzoato de estradiol (día 0). El día siete se removió el dispositivo intravaginal y de inmediato las vacas fueron inyectadas vía intramuscular con 0,150 mg de D-cloprostenol. Al día siguiente (día ocho), las vacas fueron inyectadas vía intramuscular con 1 mg de benzoato de estradiol. Entre 52 y 56 horas posteriores al retiro del dispositivo intravaginal (día nueve), las vacas se inyectaron vía intramuscular con GnRH o Kisspeptina-10. Las vacas se asignaron a cuatro tratamientos: T1, 100 µg de GnRH (control positivo), T2, T3 y T4 500 µg, 1000 µg y 1500 µg de Kisspeptina-10, respectivamente. La ovulación se detectó mediante ultrasonografía a los cuatro días post-tratamiento. La variable de respuesta evaluada fue la tasa de ovulación. Los datos se analizaron mediante modelos lineales generalizados y se aplicó una función liga logit. Resultados. Las tasas de ovulación obtenidas con T1 y T4 fueron iguales estadísticamente (99,9 %; p>0,05) y mayores (p<0,05) que las logradas con T2 (98,5 %) y T3 (88,4 %), estas dos últimas fueron iguales estadísticamente (p>0,05). Conclusión. La Kisspeptina-10 fue tan efectiva como la GnRH para inducir la ovulación.

Published: January 2024

Introduction. Chickpea has been considered a restricted host species for nodulation, although recent studies describe a greater bacterial diversity associated with the crop, which can enhance our understanding of this symbiosis to obtain efficient isolates in its contribution. Objective. To characterize and identify an isolate obtained from chickpea nodules and evaluate its effectiveness under field conditions. Materials and methods. The research was conducted in the laboratories of two centers: the Institute of Fundamental Research in Tropical Agriculture "Alejandro de Humboldt," Cuba, and the National Center for Genetic Resources, Mexico, as well as under field conditions in two campaigns to demonstrate its effectiveness in crop interaction in the first center during the years 2018 and 2020. The isolate R3 showed morpho-physiological and biochemical characteristics similar to rizobia and it was taxonomically identified through the sequencing of four genes. For laboratory experiments, a completely randomized design was used, while plant trials were conducted under a randomized block design. The results were subjected to analysis of variance, and means were compared using the Tukey test (p<0.05). Results. The isolate R3 showed variability in terms of its morpho-physiological-biochemical characteristics. Furthermore, it exhibited significant differences compared to the other treatments in the growth and yield indicators evaluated in chickpea. Conclusions. Rhizobium pusense associated with chickpea nodules was identified for the first time in Cuba. The strain demonstrates positive growth at pH levels between 5.5 and 9.0 and temperature ranges from 29 °C to 38 °C, indicating its tolerance to these factors. Its inoculation in chickpea stimulates nodule formation and increased yield-related variables.

Authors: Rohimah Salma Puji
Published: January 2024

Empowerment of Small and Medium Enterprises (SMEs) and Cooperatives have a crucial role in national development based on a people's economic system, with the aim of not only reducing income disparities and employment, but also achieving economic inclusiveness and justice. Islamic banking is a financial institution that acts as an intermediary in financial matters by complying with Islamic sharia principles, collecting, managing and distributing funds to the public. This study uses a qualitative descriptive analysis method to examine the roles and products offered by Islamic banking to SMEs and cooperatives. The results of the study show that the products offered, such as murabaha, musyarakah, and people's business loans, contribute to advancing SMEs and cooperatives. In addition, Islamic financial institutions continue to innovate with various banking products and services, supporting sustainable economic growth. Thus, empowering SMEs and cooperatives through sharia banking is the main foundation in supporting national development that is just, inclusive and forward-looking to achieve sustainable development goals.

Authors: Nhamo Mashavira , Mildred Mahapa
Published: January 2024

The challenges of staff retention and job performance persist as significant concerns for businesses, particularly in the context of Zimbabwe. While numerous studies have explored the impact of turnover intention on job performance, there is a gap in understanding the moderating variables influencing this relationship. This research aims to investigate the nuanced connection between decent work, intentions to leave, and job performance in the Zimbabwean banking sector, utilizing a quantitative approach with a causal design. The findings reveal a significant relationship between turnover intention and job performance. Moreover, it is deduced that all four pillars of decent work act as moderators in the association between turnover intention and job performance within the commercial banking sector in Zimbabwe.
The Relationship Between Visual and Abstract Comprehension in Spatial Geometry, and its Importance to Developing Spatial Perception and Vision
Authors: Dorel Lea
Published: January 2024

Spatial geometry is one of the multi-purpose fields of mathematics and is tightly linked to the development of mathematical and intellectual thinking. Spatial thinking is necessary in various areas of life such as civil engineering, mechanical engineering, interior design, graphic design
and other. At present, teaching spatial geometry is mainly based on mathematical logic – precise wording and arguments – rather than sketches and models. This mode of teaching allows teaching and defining definitions, axioms, or arguments, but does so without sufficient reference
to the spatial aspect, which is characteristic of geometry. In this article, we examined if the use of technological tools to display 3-D geometric objects during engineering studies improve the students' spatial thinking.

Authors: Santos Vanda , Vaz-Rebelo Piedade , Bidarra Graça
Published: January 2024

The introduction of games as a teaching and learning strategy in the classroom is a pedagogical resource that presents excellent results, as it creates situations that allow the students to develop problem solving methods, stimulate their creativity and at the same time generate motivation.
The theories of learning are used to describe the motives and processes of learning and teaching methods. In order to analyse the cognitive dimensions inherent in the teaching and learning process, we can consider Bloom's taxonomy. The present study was with students of 1st cycle studies,
Bachelor's Degree, in the 2nd semester in the curricular unit Learning and Teaching Models. Several games were developed by the students based on the Poly-Universe material, with the objective of being used in classroom contexts with students. The conclusions of this study are very positive,
as the students got involved in creatively playing games, drawing up a document with the rules of their created game.
The Impact of the Use of the GeoGebra Dynamic Geometry Program on Students' Understanding of the Concept of Linear Functions
Authors: Pihlap Sirje , Veermans Koen , Hannula-Sormunen Minna
Published: January 2024

This paper aims to clarify how the use of the GeoGebra dynamic geometry program helps students understand the relationships between different representations of a linear function and develop the ability to plot a linear function. The study was based on a quasi-experimental design. In
control classes, the topic of functions was presented without using computers for learning. In experimental classes, computers were used in addition to traditional instruction. The control group had 84 and the experimental group 128 students. The results of the study suggest that students'
understanding of the linear function and their skills to explain need to be developed in both, the experimental and control groups. Since the experimental group students performed better, the results of this study may encourage teachers to use the dynamic geometry program when teaching linear
functions. For productive computer use it is necessary to design tasks that guide students to discover links between different representations of the linear function.
From Space to Maths and to Arts: Virtual Art in Space with Planetary Orbits
Authors: Dana-Picard Thierry Noah , Hershkovitz Sara
Published: January 2024

Relying on the students' cultural background to teach mathematics may be a strong incitement for the learning process. This background can include artistic creations, items from the news, among others. Because of the strong presence of space related news (in particular the almost simultaneous
launching of three spacecrafts towards Mars), we present activities in a technology-rich environment, using both a Dynamic Geometry System and a Computer Algebra System. We start from a simplified model of planetary orbits and building new knowledge on plane curves. Interesting byproducts
are the discovery of the strong influence of changing numerical approximations, non – trivial aspects of the study of periodicity, the plotting of interesting curves and their connections with existing pieces of visual art, including architecture and mandalas. The educative aspect of
these activities is also discussed and is presented from the point of view of STEAM Education.

Authors: Meenakshi1 S. , Muhiuddin G. , Al-kadi Deena , Elavarasan B
Published: January 2024

The fuzzy set is an excellent solution for dealing with ambiguity and for expressing people's hesitation in regular life. Soft set theory is an innovative method for solving practical issues. This is useful in resolving a number of problems, and a lot of progress is being made at the moment. In order to develop hybrid structures, Jun et al. fused the fuzzy and soft sets. In this paper, the notion of hybrid bi-ideals in near-subtraction semigroups is proposed and their associated results are discussed. The notion of hybrid intersections is examined. Furthermore, we establish some results related to the homomorphic preimage of a hybrid bi-ideal in near-subtraction semigroups.

Authors: Atmania Rahima , Settara Loubna
Published: January 2024

In the present paper, we are concerned with an inverse source Cauchy weighted problem involving a one-dimensional diffusion equation with a time-fractional Riemann-Liouville derivative with $0<\alpha <1$. We start with results on the existence and regularity of the weak solution of the direct problem. Then, we investigate the invertibility of the input-output mapping defined by the additional over-determination integral data in order to the determination of the unknown time-dependent source coefficient.
Numerical-analytic successive approximation method for the investigation of periodic solutions of nonlinear integro-differential systems with piecewise constant argument of generalized type
Authors: CHİU Kuo-shou
Published: January 2024

In this paper, we focus on investigating the existence and approximation of periodic solutions for a nonlinear integro-differential system with a piecewise alternately advanced and retarded argument of generalized type, referred to as DEPCAG. The argument is a general step function, and we obtain criteria for the existence of periodic solutions for such equations.

Our approach involves converting the given DEPCAG into an equivalent integral equation and using a new approach for periodic solutions. We construct appropriate mappings and employ a numerical-analytic method to investigate periodic solutions of the ordinary differential equation given by A. M. Samoilenko.

Additionally, we use the contraction mapping principle to demonstrate the existence of a unique periodic solution.

Authors: Santos Jefferson do Carmo Andrade , Boa Sorte Paulo
Published: January 2024

This paper aims at presenting and discussing data from research done through an experience in two campuses of a Federal Institute of Education, Science and Technology in Northeast, Brazil, based on theories concerning digital literacies, education, and technology. As to this paper, digital literacies are understood as social practices regarding the use of digital devices as well as the hybrid performances with technologies of varied supports, such as analog and electronic devices that have been emerging since the last century. Structured observations and narrative interviews were the instruments adopted for data collection, and the analytical method was based on Freeman (1998) along with Auerbach and Silverstein's (2003) coding mechanisms. As a result, the emerging topics highlighted social use of technologies, the relevance of problematizing and thinking about meanings of the term technology as well as the importance of implementing social practices focused on the hybridization of devices instead of on the dissociation of technologies.

Authors: Signorile Pietro Giulio , Dominici Sabrina , Viceconte Rosa , Baldi Alfonso
Published: January 2024

Endometriosis, a very common disease in women, is characterized by endometrial structures outside the uterine cavity. The lack of a reliable noninvasive diagnostic test and the often nonspecific symptoms of this pathology are responsible for the delay in definitive diagnosis of this disease. Recently, through a proteomics approach, our research group has identified two potential diagnostic markers for endometriosis in serum (Zn-alpha2-glycoprotein and complement C3 precursor). In this article, we describe the experimental conditions of a simple ELISA for rapid quantification of these two biomarkers in the saliva of patients with endometriosis. Finally, preliminary experiments on a small cohort of patients and controls have confirmed the potential diagnostic value of this assay.
AS PROVAS ILÍCITAS NO PROCESSO PENAL E A TEORIA DOS FRUTOS DA ÁRVORE ENVENENADA
Authors: LUCAS PINHEIRO GUILHERME
Published: January 2024

This is an exploratory research whose object of study was the institute of illicit evidence and the theory of the poisoned tree fruits. The study addressed the issue of the (in)admissibility of illicit evidence in criminal proceedings and the legal consequences of using illicit evidence and evidence derived from illicit sources in criminal proceedings. It was demonstrated during the study that the principle of legality is one of the pillars that support the Rule of Law. According to this principle, illicit evidence cannot be used in criminal proceedings as it violates the constitutional rights of the accused. Furthermore, the theory of the poisoned tree fruits, our study topic, is one of the techniques used to exclude evidence obtained illegally. According to this theory, evidence obtained unlawfully is not accepted by the Brazilian legal system, as stated in Article 157, § 1 of the Criminal
On the Issue of Protecting the Rights of Participants in Shared-Equity Construction in the Bankruptcy Procedure of the Builder
Authors: Kostyunina Olga , Tolstikova Olga , Yakimova Ekaterina
Published: January 2024

The purpose of the study is to update the problem of restoring the balance of interests of creditors – participants in shared-equity construction in the bankruptcy case of the developer. We are talking not only about the priority protection of the rights and legitimate interests of citizens as participants in the construction, but also other persons who are not related to those within the meaning of bankruptcy legislation and suffered as a result of the bankruptcy of the debtor-builder. There is a lack of certainty in the implementation of legal regulation, which negatively affects the existing judicial practice. The current legal regulation assumes the unequal status of participants in shared-equity construction within the framework of the bankruptcy procedure, which has become the subject of constitutional proceedings. The relevance of the study lies in the assessment of the changes made in 2019 to the Law on Equity Participation in Construction and the position of the Constitutional Court of the Russian Federation, expressed in the Resolution of July 21, 2022. The practical significance of the study is determined by the conclusions made by the authors of the article and expressed in an attempt to state the emerging contradictions in the legal positions of courts of various instances on the protection of the rights of participants in shared construction in the bankruptcy procedure of the developer.
The article also considers certain aspects of the transition of the rights and obligations of the developer to the public law company «Fund for the Development of Territories», acting in order to protect the rights of citizens – participants in shared construction. It is emphasized that the Fund has no obligations to fulfill the obligations of the builder to collateral creditors. There is a contradictory law enforcement practice on this issue. It is concluded that it is necessary to further improve the legislative regulation of mechanisms for protecting the rights of participants in shared construction.

Authors: Kochetkova Irena , Osipova Marina
Published: January 2024

In the Russian Federation, the retail lending market is a rapidly growing and developing segment of the financial market, and despite the current economic situation in the country, there is a significant increase in the volume of consumer loans issued. The level of debt burden of the population is also rapidly increasing. Banks and other credit organizations are forced to contact collection agencies to return overdue debts. The actions of employees of collection agencies often go beyond the legal framework, generating new types of crimes with their illegal actions. This article is devoted to the study of the peculiarities of the forensic characteristics of crimes committed by employees of collection agencies against debtors and their relatives. For a comprehensive study of this phenomenon, an analysis of various points of view regarding the legal nature, essence and structure of the forensic characteristic of the crime is carried out. As a result of the study, elements of the forensic characteristics of crimes committed by employees of collection agencies against debtors and their relatives, the most significant crimes for this category, were identified and examined in detail. The authors attributed to them tools and means, traces of a crime, the place and time of the crime. The article also traces possible correlation links between these structural elements of the forensic characteristic. The method of committing a crime by employees of collection agencies against debtors and their relatives allows the applicant to identify and trace his relationship with such elements of the crime mechanism as tools and means of committing it, traces (both material and ideal), which displayed the method and tools used, the influence of the place and time of committing a crime on their choice. In conclusion, the author, summarizing the information studied, draws conclusions about the effectiveness of using the forensic characteristics of crimes committed by employees of collection agencies in relation to debtors and their relatives in practice to create private forensic methods.

Protocols for selective injection of tracer into the gastric mucosa and the gastric muscle of rat v1
Authors: Furness John , Stebbing Martin
Published: January 2024

This protocol is for injection of neural tracers into the wall of the stomach to identify neurons innervating various tissues in the gastric wall including the gastric mucosa and the gastric muscle/myenteric plexus. This includes extrinsic neurons such as vagal efferent and afferent neurons, sympathetic and sensory neurons, as well as intrinsic neurons in the enteric plexuses, both locally and within other parts of the digestive tract, for instance the duodenum. It utilises tracer substances that are known to be taken up by the endings of neurons, including fast blue, which is taken up very efficiently by axons, but also fluorescent microspheres whose diffusion within tissues is limited so that they can be localized to particular tissues.
Educating for expected failure?
Authors: Conradie Ernst M.
Published: January 2024

This contribution takes as a point of departure an assessment of the impact of the digital divide with specific reference to the education sector in the South African context. A core problem is clearly that such a large proportion of learners drop out of secondary schools, while the pass rates at Bachelors level are also alarming. Does this imply that education takes place with a view to expected failure? This contribution explores the question what perspective Christianity and Christian theology can bring to this social reality. It suggests that this perspective is related to the perplexing question what education is there for in the first place. It surveys various options in this regard (knowledge, skills, virtues, values, worldviews) and then argues that education is also about developing interpretative and integrative frameworks, learning to see the world around us in a way that makes sense. On this basis various strategies to cross the deep divides in the South African education system are suggested. However, it is argued that “crossing” the digital divide should not be reduced to offering soteriological answers to questions regarding the nature of education that are primarily ontological in nature.
Personal mobile devices and mental health: A double-edged sword?
Authors: Bentley Wessel
Published: January 2024

It has been well documented that there is a correlation between the (over) use of social media and the rise of mental health disorders, especially dependency, depression, anxiety, narcissism, and other behaviour- and mood disorders. The use and functionality of personal mobile devices seized the opportunity to offer individualised and personalised therapeutic services such as applications for mindfulness, exercises to manage depression and anxiety and even to facilitate meditative practices (spirituality). One is then left undecided whether the use of personal mobile devices can be counted as a vice or a blessing. This article will explore impact the use of personal mobile devices have on mental health and the question of being human. It does so within the science and religion discourse.

Published: January 2024

The article deals with the information system, which is a prototype of an adaptive simulator created on the basis of the realization of Markov processes for psychological diagnostics, adapting the difficulty and complexity of tasks in accordance with the diagnostic assessment in real time. The description of the system for adaptive diagnostics of user readiness level based on Markov models is presented. The system allows estimating the user's readiness level by giving him/her tasks of different difficulty and complexity according to the Markov process. An algorithm for creating tasks with a high order of detailing the complexity gradient, on the example of the subject area of professional counseling, for the purpose of diagnosing abilities is formed. In case of incorrect answers or exceeding time limits, the user falls into a "trap" where he/she receives simpler tasks with hints. Examples illustrating the application of the information system are given, as well as the results of approbation.

Food and Agriculture Organization (FAO) mengkategorikan ikan ke dalam salah satu dari delapan jenis bahan pangan yang umumnya menyebabkan reaksi alergi pada individu sensitif. Manifestasi klinis yang disebabkan alergi ikan bervariasi mulai dari gejala ringan hingga berat, bahkan sampai mengancam jiwa. Teknologi proses pengolahan terbukti dapat mengubah alergenisitas ikan dengan efektivitas yang berbeda. Penelitian ini bertujuan untuk menentukan teknologi proses pengolahan yang efektif dalam menurunkan alergenisitas ikan melalui metaanalisis. Diperoleh 12 artikel jurnal yang diseleksi berdasarkan diagram PRISMA. Data dianalisis menggunakan efek ukur standardized mean difference (SMD) dengan 95% confidence interval (95% CI). Teknologi proses pengolahan non-termal (ultraviolet radiation (UV-R) dan high-hydrostatic pressure (HHP)) serta reaksi Maillard memiliki efek signifikan dalam menurunkan alergenisitas ikan. Sementara itu, proses pengolahan termal konvensional tidak berpengaruh signifikan dalam menurunkan alergenisitas ikan. Nilai SMD menunjukkan bahwa aplikasi teknologi proses pengolahan non-termal paling efektif dalam menurunkan alergenisitas ikan. Pada tingkat seluler, teknologi proses pengolahan secara signifikan menurunkan pelepasan sitokin (IL-4 dan IL-13) dan mediator inflamasi (histamin, tryptase, dan b-heksosaminidase).

Ikan tuna asin kering merupakan salah satu bentuk hasil olahan ikan tuna undersize yang dibuat oleh masyarakat di sekitar Perairan Maluku. Pengolahan bahan baku menjadi ikan asin bertujuan untuk mengawetkan ikan agar tidak cepat busuk dan lebih tahan lama. Bahan pengawet yang biasanya digunakan produsen ikan asin, yaitu garam dan beberapa juga menambahkan bahan pengawet yang sudah dilarang penggunaannya karena berbahaya bagi tubuh. Atung (Atuna excelsa subsp. racemosa) merupakan tanaman endemik Maluku yang dapat digunakan sebagai bahan pengawet alami untuk produk pangan. Penelitian ini bertujuan untuk menentukan perlakuan terbaik perendaman bertingkat garam dan larutan biji atung dalam menghasilkan ikan tuna asin kering berdasarkan parameter kimia, mikrob, dan organoleptik. Ikan tuna sirip kuning difilet, direndam dengan larutan garam perlakuan 5% dan 10% lalu dilanjutkan direndam dengan perlakuan larutan atung 3%, 4%, dan 5%. Parameter yang diamati meliputi kadar air, protein, garam,  Total Plate Count (TPC), dan organoleptik (ketampakan, bau, rasa, dan tekstur). Hasil penelitian menunjukkan bahwa perbedaan konsentrasi garam dan larutan atung memengaruhi kadar air, protein, garam, TPC, dan organoleptik ikan tuna asin kering. Perlakuan penambahan garam 10% dan larutan atung 4% merupakan perlakuan terbaik dengan kadar protein tertinggi 70,59±0,52%, air 27,27±0,14%, garam 4,30±0,05%, kandungan TPC 1,37x103 cfu/g, dan penilaian sensori secara keseluruhan disukai panelis.
High-Resolution 3D QP and QS Models of the Middle Eastern Boundary of the Sichuan–Yunnan Rhombic Block: New Insight into Implication for Seismogenesis

Published: January 2024

The eastern boundary of the Sichuan–Yunnan rhombic block (EB-SYRB) has complex structures and strong seismicity. Although multiple 3D high-resolution velocity models have been constructed for this region, its seismogenic environment has been controversial. Seismic wave attenuation (inversely proportional to Q) describes the anelastic properties of the Earth’s medium, and is more sensitive to changes in subsurface fluid and temperature than seismic wave velocity. Based on the data of a long-term dense array in downstream of the Jinsha River, this article uses local earthquake tomography to obtain 3D QP and QS models of the middle EB-SYRB with the highest resolution to date, improving the lateral resolution of the Q model from 100 km to 5–10 km and the depth resolution from 10 to 2 km. Combined with the existing high-resolution velocity and resistivity models and geochemical observation results, we can comprehensively understand the medium structure and the seismogenesis in the study area. The results show that the high-attenuation characteristics in the shallow layer of the Xiaojiang fault zone and the Zemuhe fault zone (within a depth of ∼5 km) are consistent with the topographic relief and the distribution of hot springs, which reveals the Quaternary sedimentary characteristics of the basins and the presence of shallow fluids in the fault zone. The columnar high-attenuation anomaly beneath Huize reveals the fluid channel created by deep melting. The Ludian earthquake sequence occurred in a prominent low-attenuation area, which is favorable for stress accumulation and has a seismogenic environment for strong earthquakes. The high attenuation near the southwest end of the Huize fault is closely related to the Huize earthquake cluster, which is driven by fluids in the upper crust.

Addressing developmental and learning lags for preschoolers living in impoverishment is of critical interest to educators and policy makers as children who experience such lags are at risk for a significant number of adverse outcomes reaching into adulthood. However, the landscape of preschool is a fractured one with no standards across a wide variety of programs spanning public, private, and religious institutions. Art therapy may support early learning through relationship-based interventions in a classroom that are designed to promote visual-motor integration, fine motor skills/drawing, and expressive and receptive language development. This study was a preliminary exploration of the potential effects of an art therapy intervention program on the development of emergent literacy as a measure of school readiness, on preschool children in state supported preschool in a high poverty neighborhood in Philadelphia. A quasi-experimental, mixed-methods design used standardized measures and qualitative art and verbal/narrative data to explore if and how art therapy impacted student emergent literacy and response to intervention. Findings suggest a clinically relevant impact of the art therapy intervention on visual-motor integration, fine motor/drawing, and statistically significant impact on language/communication skill development with student improvement related to emergent literacy skills, meta skills, and social/emotional functioning with an experience of heightened engagement and joy.
