The present work aims to study the general and specific combining capacity of the varieties involved in the crossing according to the complete diallel scheme. The trial undertaken in randomized block with four (4) replications, on mineral nutrition (N24 P 12K 12 low background, N48P24K24 high background) was carried out in the experimental station of the National Institute of Agronomic Research of Brazzaville (IRA) in the Republic of Congo.

This research investigates the impact of discipline and disciplinary procedures on effective service delivery in the Nigerian public service. It examines the existing disciplinary framework, its implementation challenges, and the perceived effectiveness of disciplinary actions in improving public service performance. The study utilized the bureaucratic theory as its theoretical framework in understanding discipline and disciplinary procedures and effective service delivery in Nigeria's public service.

Our ethnobotanical survey was carried out among 29 healers and phytotherapists in the city of Goma. From this study, 26 plant species belonging to 24 genera and 19 families used against snake bites have been inventoried. The Asteraceae family (4 species and 4 recipes) is the most represented, followed by the Malvaceae and Verbenaceae families (2 species). The leaf is the most widely used organ, trituration is the most widely used preparation method, and the poultice is the most widely adopted method of administration.

This study presents the design, development, and implementation of an RFID-based Verification System for managing gate entry and exit at Eastern Visayas State University – Ormoc Campus (EVSU-OC). Addressing the limitations of manual identity verification processes, the system was developed using agile methodology, integrating stakeholder feedback across iterative cycles to enhance usability and functionality.

The article analyzes the point of view of women in Higher Education in Cabinda, about challenges and ethics in professional life. These points of view were collected through a questionnaire survey with closed questions, on a Likert scale from 1 to 5. The answers from the 25 women interviewed were processed using simple statistics, with the support of the SPSS program, and the opinions regarding open questions were not subject to analysis, taking into account that the study required in-depth data in a timely manner.

The emerging topic of quantum computing holds promise for transforming many facets of science, technology, and society. Using the ideas of quantum physics, quantum computing has the potential to completely transform the computing industry by resolving challenging issues that are nearly unsolvable for traditional computers. Examining quantum computing's possible uses and future is the goal of this research article. It illustrates the difficulties in creating workable quantum computers and investigates the fundamental ideas of quantum physics.

To understand the internal structure of a black hole, we must understand the concept of “state of compactness” of matter, that is to say a very high level of mass/energy potential in space (GeV/cm²). This level is in the black holes and at the beginning of the universe (Big Bang). In the first case, it is a collapse of matter from gravitational fields and in the second, an expansion of space due to repulsive fields.

The eyes, as highly metabolically active organs, depend on a steady supply of key nutrients to maintain optimal function and prevent degenerative conditions. This review highlights the critical role of diet in vision health, emphasizing essential nutrients such as vitamin A for night vision, omega-3 fatty acids for tear production, and lutein/zeaxanthin for macular protection.

Chosen families, composed of non-biological kinship networks, play a transformative role in enhancing mental health and resilience among queer individuals. This dissertation examines the impact of peer support networks on mental health outcomes and resilience among queer individuals. These networks provide unconditional emotional support, reduce feelings of isolation, and foster a sense of belonging, particularly in cases where traditional family structures may fail to offer adequate affirmation or acceptance.

In this paper equations for words formation were derived. Information processing and treatment was defined. The law of frequencies interaction and transposition was defined. Equations of frequency dependence of time and space were derived. Quality of information, letters, vowel, consonant, length of word, pause and the others attributes (insertion, deletion) determine frequency variability and interactions between different frequencies. Diffusivity effect to the information formation was defined. In this paper information value of word was derived.
