Objetivou-se avaliar o efeito da adubação nitrogenada sobre a produção de forragem de cultivares de brachiarias, bem como observar se esse manejo pode interferir na estacionalidade da produção entre as estações água e seca. O período experimental compreendeu o período da seca e das águas da safra 2021/2022. As cultivares Marandu, Mavuno, Xaraés, G172, G153 e G156 foram distribuídas nas parcelas, em delineamento de blocos ao acaso. No entanto, nas subparcelas foram alocadas as adubações de cobertura (0 a 80 kg ha-1 N), as quais foram divididas em duas doses de 40 kg N ha-1, aplicado no período das águas, entre os meses de novembro e janeiro, época de maior volume de chuva, com quatro repetições por tratamento, totalizando 48 unidades experimentais. A cultivar Marandu foi utilizada como balizador do manejo da desfolhação, e os cortes foram realizados quando esta alcançava entre 35 a 40 cm no período das águas. Não houve interação entre as cultivares de brachiárias e adubação para as variáveis do período da seca. Para variável porcentagem de lâmina foliar as cultivares G153 e G172 apresentaram maiores valores no período das águas. A cultivar Mavuno destacou-se no número de folhas vivas por perfilho com 2,35 folhas. Para a variável densidade de perfilhos, as cultivares G153, G156 e Marandu apresentaram maiores valores das demais cultivares quando não houve adubação. Em contrapartida, quando as cultivares receberam adubação, a G153 apresentou uma maior quantidade de perfilhos. Observou-se que as forrageiras no período das águas apresentaram uma maior produção, com destaques para as variáveis acúmulo de forragem, acúmulo de lâmina foliar e porcentagem de lâmina foliar. Mesmo com a adubação de 80 kg N ha-1, dividido em duas aplicações de 40 kg N ha-1, nas águas, não houve efeito residual no período de seca.

A classification of Hadamard matrices of order $2p+2$ with an automorphism of order $p$ is given for $p=29$ and $31$. The ternary self-dual codes spanned by the newly found Hadamard matrices of order 60 with an automorphism of order 29 are computed, as well as the binary doubly even self-dual codes of length 120 with generator matrices defined by related Hadamard designs. Several new ternary near-extremal self-dual codes, as well as binary near-extremal doubly even self-dual codes with previously unknown weight enumerators are found.
Correlation of Soluble Programmed Death Ligand-1 (sPD-L1) with Alpha-Fetoprotein Levels as a Predictor of Prognosis in Hepatocellular Carcinoma Patients
Authors: Chaerunisah Sari , Suyata  , Mgs M. Irsan Saleh  
Published: February 2024

Background: Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and one of the leading causes of cancer death worldwide. Chronic hepatitis B virus infection is the most common etiology of HCC. Programmed death ligand-1 (PD-L1) is a protein that is overexpressed on the surface of tumor cells, which can be detected in serum (sPD-L1). Elevated sPD-L1 concentrations in the plasma of cancer patients are associated with poor prognosis in HCC patients, as indicated by increased AFP levels. There have been no previous studies examining the correlation of sPD-L1 levels with AFP in HCC patients. The aim of the study was to determine the correlation of sPD-L1 and AFP as predictors of prognosis in HCC patients.
Methods: The research is an observational study with a cross-sectional design to see the correlation of sPD-L 1 with serum alpha-fetoprotein levels in HCC patients at Dr. Mohammad Hoesin General Hospital Palembang starts from April to July 2023. Measurement of sPD-L1 levels and serum AFP levels is carried out using ELISA examination.
Results: Of the 28 subjects studied, HCC patients were more commonly found in men (89.29%) aged 18-60 years (75%). sPD-L1 and AFP values were found to be increased in the advanced stages of HCC. The sPD-L1 value is directly proportional to the serum AFP value.
Conclusion: There is a strong positive correlation between sPD-L1 levels and serum AFP levels caused by hepatitis B in HCC patients, so the higher the sPD-L1, the higher the serum AFP levels.
Collisional Shaping of Nuclear Star Cluster Density Profiles
Authors: Rose Sanaea C. , MacLeod Morgan 
Published: February 2024

Abstract
A supermassive black hole surrounded by a dense, nuclear star cluster resides at the center of many galaxies. In this dense environment, high-velocity collisions frequently occur between stars. About 10% of the stars within the Milky Way’s nuclear star cluster collide with other stars before evolving off the main sequence. Collisions preferentially affect tightly bound stars, which orbit most quickly and pass through regions of the highest stellar density. Over time, collisions therefore shape the bulk properties of the nuclear star cluster. We examine the effect of collisions on the cluster’s stellar density profile. We show that collisions produce a turning point in the density profile, which can be determined analytically. Varying the initial density profile and collision model, we characterize the evolution of the stellar density profile over 10 Gyr. We find that old, initially cuspy populations exhibit a break around 0.1 pc in their density profile, while shallow density profiles retain their initial shape outside of 0.01 pc. The initial density profile is always preserved outside of a few tenths of a parsec irrespective of initial conditions. We generalize this model to an arbitrary galactic nucleus and show that the location of the collisional break can be simply estimated from the nuclear properties. Lastly, we comment on the implications of collisions for the luminosity and color of stars in the collisionally shaped inner cluster.
Emerging methodologies and technologies applied to university education
Authors: Romero Oliva Manuel Francisco , Heredia Ponce Hugo , Amante García Beatriz , Martínez Martínez María 
Published: February 2024

Education, in general, is part of a changing and liquid society (Bauman & Donskis, 2019) that has to evolve in tune with the changes occurring in the educational ecosystem. In this context, technologies appear that are gradually being incorporated into the educational environment and, consequently, new forms of teaching appear, i.e., the so-called emerging methodologies (Cabero-Almenara et al., 2022; Villamarin-Reinoso et al., 2022). The incorporation of these require a reflection based on experimentation, research and, therefore, on evidence that can support new educational models in teacher training to meet social challenges and the formation of citizens in the interpretation of reality and their realization as people. These methodologies cause the students to play an active role in the whole teaching-learning process and require teachers to undergo ongoing training in order to incorporate them and work in the classroom from a pedagogical, didactic and technological approach (augmented reality, flipped classroom, design thinking, gamification, m-learning...). Hence, talking about emerging methodologies goes beyond talking about technological renovation and integration, which are key aspects in these approaches, but also means thinking about the inclusion of participating voices in the educational processes from the interaction and democratization of the classroom (educational diversity and inclusion). In this sense, university education is not left behind, since "it must innovate in its teaching-learning processes and provide different means that help students to generate new ideas creatively, acquire skills adapted to the needs of the labor market and learn to respond appropriately to the demands of the environment". (Fernández-Piqueras, et al. 2020, p.185). Therefore, the incorporation of these methodologies can favor the teaching-learning process in all areas of knowledge, but first the following questions should be rethought: how are we currently teaching, for whom are we teaching, what are we teaching for, etc.? Ultimately, the aim of this special issue is to answer these questions and to reflect on the teaching of the future and the changes we need to make to make it truly effective and efficient, so that students learn and adapt to the demands of the future.
Optimising Subsea Natural Gas Pipeline Inspection Using CFD
Authors: Rostam Farahin , Chauvet Christian , Jagannatha Deepak 
Published: February 2024

Abstract
Subsea pipeline inspections require large amounts of chemicals and procedures, which costs money, time, and energy. This paper showcases the use of Computational Fluid Dynamics (CFD) tool to help optimize this process by studying the feasibility of replacing nitrogen gas with a single Tri-ethylene Glycol (TEG) filling process in one of the natural gas fields located at north-western coast of Australia.
To determine the feasibility of using only a single TEG filling process, a few scenarios had to be studied for their environmental and operational impact. The first scenario is to determine how effective TEG is at removing seawater inside the Pig Launch Receiver (PLR), which was initially pre-loaded with the In-Line Inspection (ILI) tool and filled with 100% TEG, then connected to the Gas Export Line (GEL) at the seabed, temporarily exposing it to the seawater environment. Another scenario involves the removal of natural gas inside the PLR after the ILI tool launches. The study compares the use of expensive nitrogen purging against the cheaper option of pumping TEG. The final scenario involves the environmental impact of lifting the PLR back to the surface filled with TEG and natural gas vs. nitrogen.
Conclusions were drawn based on the CFD study. In the first scenario, it could be concluded that there was minimal seawater ingress into the PLR, and a TEG purge after installation was adequate to remove most of the seawater ingress. In the second case, it was proven that injection of TEG was sufficient to remove most of the export gas from the system, leaving minimal trapped gas in the system. The final case showed that there were mostly TEG and minimal natural gas escaping to the environment during lifting, making the process of a single TEG filling process viable.
The study demonstrates how the use of advanced technology such as CFD has reduced the use of expensive chemicals compared to just using simple calculations and field experience. It has also allowed to reduce the duration of the intervention, saving cost and energy.
Pipeline Leak Mechanisms
Authors: Bridge C. D. 
Published: February 2024

Abstract
This work investigates the mechanisms that occur when a pipeline leaks. A thorough understanding of the pipeline leak mechanism is the primary building block that must be understood fully prior to selecting technologies for leak detection. With an expectation of the greatest failure risks, the most significant leak mechanism(s) can be deduced and subsequently the strengths and weakness of leak detection technologies ranked against the pipeline operator’s operational philosophy requirements (e.g., is the operator looking for an accurate position of a leak or a probable area of concern) compared with accuracy of detecting a leak and reducing false positives. It is not within the scope of the work to consider methodologies for leak detection.
Severe Sour Pipeline Lateral Buckling Mitigation Design Optimisation
Authors: Shariff Shehzada , Bezensek Bostjan 
Published: February 2024

Abstract
This paper presents the optimisation journey of lateral buckling mitigation design for a severe sour service pipeline. The journey, which was in a front-end stage of a project, involved preliminary in-environment fracture toughness testing program, preliminary engineering critical assessments (ECA), and pipeline design activities to achieve a feasible pipeline design.
A thermal buckling study concluded that the pipeline is susceptible to lateral buckling with unacceptable consequences. Lateral buckling mitigation options were investigated and confirmed that the Zero Radius Bend (ZRB) buckle trigger remains an effective solution. The pipeline design thus focused on the optimization of the material, number of the trigger points, and its locations.
In-environment fracture toughness testing program was conducted using representative girth welds made by carbon steel consumables and representative carbon steel pipes to cater for the required design scenarios. Concurrently, an ECA was performed to establish allowable pipeline longitudinal stresses as input to pipeline design for optimization of lateral buckling mitigation measures. This assessment was iterative to define a compromise between the welding acceptance criteria, the material capacity (fracture toughness in sour) and the number of buckle triggers to be installed. The ECA outcome provided the allowable longitudinal stress for use in the pipeline design.
Normally, ECA is performed in the execution stage of a project to define the welding acceptance criteria for known material properties and final pipeline design stresses. It is also common that pipeline design is driven by factors that do not consider the material capacity limitations on large stress (strain) utilisation in sour service and rather aim to comply with a given design code. It is less commonly known that these design codes do not account for significantly reduced carbon steel material properties in severe sour therefore there is a gap in the pipeline design codes.
The main learnings from this journey are that allowing for pipeline utilisation up to the SMYS value of the material (defined at 0.5% strain in DNV-ST-F101 and API 5L) is not safe for sour pipeline design in severe sour conditions (NACE TM 0175 Region 3). Instead, severe sour pipeline design should: (1) Not exceed the Sulphide Stress Cracking (SSC) material qualification stress limits; and (2) Satisfy ECA defined limits for the longitudinal stress in the girth weld. If these are not considered, the pipeline may (i) initiate cracking in the crown of the lateral buckle in service due to SSC degradation, (ii) it may become impractical to construct if the welding acceptance criteria become too stringent in the execute project phase, or (iii) it may be unsafe to operate for the intended design envelope.
