Effect of a liquid biofertilizer and shading levels on Etlingera Elatior
Get PDFLiquid biofertilizers, promoted by regenerative agriculture, aspire to sustainability. In this sense, the combination of concentrations of a super-lean bioslurry (BSm) based on bovine manure ("Factor A", A1: 0 ml/l control, A2: 3.5 ml/l A3: 7 ml/l and A4: 10 ml/l) and shading levels ("Factor B" B1: full sun, B2: 35% and B3: 70%), on the growth and development of Etlingera elatior was evaluated. The BSm applications were dosed in four applications, distributed over 210 days via foliar application, carrying out: measurement of plant height to the last leaf in cm (ATA cm) and rhizome weight in grams (Rz g). A randomized block design with a 4 X 3 factorial arrangement was used, resulting in twelve treatments and three replicates (36 observation units), measured at the end of the bioassay. An analysis of variance and orthogonal contrast test were applied, using the Infostat program. The results of the orthogonal contrast tests show that for the variable ATA cm, there was a negative effect when increasing the concentrations of BSm (p-value of 0.0423 < 0.05), "Factor A"; in relation to "Factor B", no significant difference was found p-value (0.4003> 0.05); as for the weight of the Rhizome (Rz g), significance was observed at α 0.05, with a shade level of 35%, without the concentrations of BSm being a determining factor

Numerical investigation of bearing capacity and lateral response of pile group considering soil interaction
Get PDFIntroduction: Piles play a crucial role in major structures like power plants, petrochemical complexes, offshore platforms, and bridges. Ensuring their safe and cost-effective design under lateral dynamic loads is essential. Due to the complexity of soil-pile interaction and the influence of multiple factors, further research is required.Objective: The main objective of this research is to investigate the parameters affecting the interaction of soil and reinforced concrete pile groups.Methods: The parameters discussed and investigated in this research include the use of UHPC concrete with different strengths instead of conventional concrete in piles, pile length, pile diameter, pile length-to-diameter ratio, and pile spacing. Results: The results of this research show that if the diameter of the pile is 0.6 meters, increasing the length from 9.15 to 11.65 meters and from 9.15 to 14.15 meters will increase the bearing capacity of the pile by 53% and 77%, respectively. In cases where the pile length is 9.15 meters, increasing the diameter from 0.6 to 1 meter results in a 58% increase in bearing capacity. Additionally, reducing the distance between piles from 1.8 meters to 0.8 meters enhances their bearing capacity by 37%. Conclusions: The findings indicate that pile dimensions and spacing significantly influence their bearing capacity. Using larger pile diameters, increasing pile length, and optimizing pile spacing can effectively enhance structural performance under dynamic lateral loads
Some considerations on the Judicial Review in Argentina
Get PDFConstitutional review is a critical mechanism for safeguarding constitutional supremacy in modern legal systems. Argentina adopted a system of judicial review based on the original U.S. model. This system, established through the Supreme Court\u27s decisions, has defined the judiciary\u27s role in the nation\u27s constitutional democracy. This paper, aims to identify and describe the core elements and characteristics of Argentina\u27s system of constitutional review. It analyzes how this system has been shaped by key jurisprudential precedents from the Supreme Court of Justice of the Nation (CSJN), exploring the unique tension between its origins in a Common Law model and its implementation in a Civil Law tradition. The research methodology is a qualitative analysis of historical legal documents and key judicial rulings. The study focuses on landmark precedents from the CSJN to trace the historical development and define the essential characteristics of constitutional review in Argentina. The paper demonstrates that Argentina\u27s system of constitutional control is a diffuse model, where all judges can exercise review. A key finding is the absence of a strict stare decisis rule, which creates a paradox where Supreme Court decisions are not formally binding but are treated as a “moral duty” for lower courts to follow for reasons of procedural economy and legal certainty. The analysis reveals that the system\u27s development was primarily “praetorian,” driven by the CSJN\u27s rulings rather than explicit legislative or constitutional mandates. The Argentine system of judicial review remains one of the few worldwide that closely follows the original U.S. model, yet it has unique features that reflect its Civil Law context. While not formally binding, the practical application of the CSJN\u27s precedents creates a de facto obligation for lower courts. This tension is central to understanding the system\u27s functionality and its implications for the protection of constitutional rights
Genetic factors associated with cleft lip and palate in children at the “William Soler” hospital, 2021 to 2022
Get PDFIntroduction: Cleft lip and palate are common congenital anomalies and the etiopathogenesis is not well understood, being fundamentally associated with polygenic or multifactorial inheritance. In nonsyndromic oral clefts, the genetic condition represents around 25% of cases. Objective. To identify the genetic factors associated with cleft lip and palate. Method. Descriptive, cross-sectional and retrospective study of 104 patients treated for congenital cleft lip and palate in the Maxillofacial Surgery department of the William Soler Ledea Pediatric Hospital from January 2021 to December 2022. The variables studied were: sex, form of presentation of the cleft, isolated congenital defects, previous siblings, intergenetic period, history of family members with congenital malformations, consanguinity of the parents and abortions. Results: The patients presented with an equal distribution by sex (p=0.890), isolated clefts (90.4%) occurred regardless of sex. The presence of previous siblings (59.6%) was significantly associated (p=0.0084), as were a history of family congenital malformations (36.5%) of second degree consanguinity (50%), and previous abortions (50%). Conclusions. The children studied with cleft lip and palate follow a homogeneous distribution by sex and only a small number presented multiple congenital defects. Slightly more than a third were associated with multiparous mothers, with a high frequency of previous abortions, and evidence of a history of familial congenital malformations, mainly of second degree consanguinity through the maternal line
