Economic Viability of Converting From Conventional to Organic Coffee Cultivation in Southern Minas Gerais
Authors: Reis Elivandro Miguel , Azevedo Luciana , Rezende Marcelo Lacerda , Rios Guilherme da Silva 
Published: June 2024

Objective: This study aims to explore the economic viability of converting conventional coffee cultivation to organic practices on a rural property in southern Minas Gerais, assessing the economic and operational impacts of this process.

Theoretical Framework: The literature on sustainability in coffee production suggests economic benefits and a reduction in negative environmental impacts for farmers who adopt sustainability certifications. However, empirical evidence is mixed, with studies indicating a dependence on financial premiums to offset the lower productivity of organic cultivation.

Method: A case study was conducted on a property that uses both production systems. Data from the 2022/2023 harvest were collected and analyzed, comparing the operational costs and profitability between conventional and organic cultivation methods.

Results and Discussion: The findings indicate that the high cost of organic inputs negatively impacted the profitability of organic production, despite the significantly higher sales prices of organic produce. The low productivity of the organic plot resulted in losses, highlighting a gap in the efficiency of production management.

Research Implications: The findings of this study suggest the need for more effective management strategies and possibly the development of agricultural technologies that increase the productivity of organic cultivation, without compromising the principles of sustainable agriculture.

Originality/Value: This study contributes to existing literature by exploring the conversion of cultivation in a specific and coffee-producing region in Brazil, providing data on the real economic challenges faced by farmers during the transition to sustainable agricultural practices. The detailed analysis of costs and benefits reinforces the complexity and nuances involved in adopting sustainable agricultural practices on a local scale.
Bounced Cheque as an Enforceable Instrument: A Comparative Study between the United Arab Emirates (UAE) & French Legislations
Authors: Al-Kattan Mhd. Samer 
Published: June 2024

Purpose: This research aims to define the bounced cheque, which is considered an Enforceable Instrument, and to clarify its cases, implementation procedures, and the conditions associated with this execution through a comparative study of the prevailing legal provisions in both Emirati and French law.

Theoretical reference: The study examines the concept of a bounced cheque as an Enforceable Instrument under the legal frameworks of the UAE and France. It analyzes the criteria, cases, and procedural requirements for executing a bounced cheque in both jurisdictions, highlighting the differences and similarities in their legislative approaches.

Method: A comparative analysis was conducted, scrutinizing the legal provisions and enforcement procedures related to bounced cheques in Emirati and French law. The study involved reviewing relevant statutes, case laws, and legal commentaries to understand the practical implications of treating a bounced cheque as an Enforceable Instrument in both countries.

Results and Conclusion: The research reveals that in UAE law, a bounced cheque is considered an Enforceable Instrument as soon as the bank notes the absence of sufficient funds or that the drawer's account has been closed. In contrast, French legislation grants Enforceable Instrument status to an unpaid cheque only after a thirty-day period, allowing the drawer time to settle the cheque's value or reach a settlement with the beneficiary. The study concludes that while both legal systems recognize the enforceability of bounced cheques, they differ significantly in the timing and conditions under which this enforceability is granted.

Implications of research: The findings suggest that while the immediate enforceability of bounced cheques in the UAE provides swift recourse for beneficiaries, the French approach of granting a grace period offers a more balanced consideration for the drawer. The research implies that incorporating a reasonable time frame for fulfilling the value of the bounced cheque, as suggested in the recommendations, could harmonize the interests of both parties involved.

Originality/value: The research provides a comprehensive comparative analysis of the enforcement of bounced cheques in Emirati and French law, offering valuable insights into the strengths and weaknesses of each system. The proposed recommendation of a balanced time frame for cheque fulfillment contributes to the ongoing discourse on optimizing legal procedures for financial instruments, potentially influencing future legislative reforms.
Speleothem in Sandstone: Maranhão as a Geo-Speleological Scenario
Authors: Castro Cláudio Eduardo de , Silva Flávia Martins 
Published: June 2024

Background: The municipality of Carolina, located in the southern region of Maranhão, features a terrain composed of hills and plateaus formed from sandstone lithology originating from the Balsas Group formations. This region houses geological features such as caves and speleothems, which pertain to endokarst, primarily formed through erosive processes. Due to its significant speleological potential, the region has been studied by the Conservation Units Research Group (GEUC) of the Maranhão State University (UEMA) since 2013.

Objective: The study aims to catalog sandstone caves. In addition to mapping and surveying these caves, a sandstone stalagmite speleothem was recently recorded, supporting studies that defend the legitimacy of karst features in detrital rocks.

Theoretical Framework: For a long time, sandstones were considered pseudo-karst. However, recent geological perspectives recognize this rock type as true karst, necessitating a deeper understanding of the intricate formative complex of exokarst and endokarst.

Methodology: To obtain research results, after reviewing scientific literature, caves were prospected based on geological, geomorphological, and slope mapping conducted in a geoprocessing environment, followed by surveying existing caves. Specifically, this study aimed to analyze the speleothem and its genesis.

Results and Discussion: This study presents a brief discussion on the possible karst formation processes, highlighting the rare occurrence of the sandstone stalagmite found in Carolina-MA and its morphogenetic process. This contributes to the originality of the research, given the scarce literature on this subject.

Research Implications: Understanding the detailed characteristics of caves and specifically their ornamentation is important in itself. In this case, studying sandstone caves in a relatively unknown area provides insights necessary for evaluating the local implications of large-scale developments, in addition to supporting geological knowledge regarding these formations.

Originality/Value: Two factors contribute to the value of this research. Firstly, it enhances geological understanding of speleothems. Secondly, in the context of the sandstones in the Parnaíba Basin, it provides valuable knowledge about the rare internal formations within these caves.

Published: June 2024

O presente estudo apresenta as nuances do instituto dos Juiz das Garantias, inserido no Código de Processo Penal Brasileiro (CPP) pela Lei 13.964 de Dezembro de 2019. Para tanto, apresenta-se o papel exercido de tal figura na persecução penal no Brasil, especialmente na fase pré-processual. Esta pesquisa permite analisar a atuação do juiz à luz da Constituição Federal do 1988 e sua aproximação ao sistema inquisitório, pois era permitida ao juiz da ação penal atuar de forma direta durante o Inquérito Policial. A partir disso, procura-se apresentar o Juiz das Garantias, solução encontrada para superar esta aproximação e orientar a construção de um juiz que atuará na fase investigativa, garantidor dos direitos humanos e fundamentais. Desta forma, humaniza-se a persecução penal, atendo-se às premissas de um sistema processual garantista. Por fim, são apresentadas as dificuldades e impasses para sua plena aplicação prática, além de avaliar sua influência na persecução penal no Brasil, concluindo que a efetiva aplicação do Juiz das Garantias pode permitir a modernização da investigação criminal, o que servirá como instrumento para diminuir a cultura inquisitória no ordenamento pátrio, além de contribuir para a busca da imparcialidade do julgador.

Published: June 2024

A depressão é caracterizada pela perda ou diminuição de interesse e prazer pela vida, pelo sentimento de tristeza e baixa autoestima, gerando angústia e prostração, cansaço excessivo, dores no corpo, ansiedade e insônia. O cloridrato de amitriptilina é um antidepressivo tricíclico, um fármaco de grande eficácia no tratamento da depressão, comprovada por inúmeros estudos clínicos, sendo um medicamento de grande importância no mercado farmacêutico. Nesse contexto, a equivalência farmacêutica tem como objetivo promover testes comparativos de qualidade entre o medicamento referência e o medicamento teste. Assim, o objetivo deste estudo foi comparar a qualidade de comprimidos de amitriptilina disponíveis no mercado, classificados como medicamentos genéricos e de referência, por meio de análises farmacopeicas. As análises quantitativas foram realizadas por espectrofotometria no ultravioleta. As amostras analisadas apresentaram qualidade adequada quanto aos testes de determinação de peso, desintegração, uniformidade de doses unitárias, doseamento e dissolução, estando em conformidade com os parâmetros farmacopeicos e apresentando eficácia e segurança de uso assegurada. Entretanto, na comparação dos perfis de dissolução, a amostra referência de 75 mg apresentou valores próximos a 80% de dissolução em menos de 15 minutos, enquanto para as amostras genérico de 75 mg e referência de 25 mg foram necessários tempos próximos a 60 minutos para atingir esse valor. Para comparação dos perfis, foi calculado o fator de semelhança (f2) entre as amostras AxB e AxC, os quais foram 10,58 e 30,65, respectivamente. Assim, as amostras não demonstraram equivalência farmacêutica nas condições testadas

Published: June 2024

Abstract
The volumetric capacity of drill pipe is critical information needed to optimize drilling operations. Currently, this is estimated using the nominal product dimensions which do not account for manufacturing variation or loss of material after use among other factors. For example, tolerances of the as-rolled wall thickness and outer diameter of manufactured tubulars can vary from nominal approximately ±5% and +1% to −0.5%, respectively, while tool joints are fully machined to high accuracy. By understanding and properly managing the volumetric capacity of drill pipe, drilling engineers can help to ensure the safety and efficiency of the drilling process. We present a method using data captured by non-destructive methods to determine the volumetric capacity of drill pipe more accurately, specifically fluid capacity, fluid displacement and adjusted weight per foot. We conclude the fluid capacity for a 15,000 ft drill string comprised of 5.5 in OD 0.415 in wall thickness 24.70# drill pipe is 304.5±8.5 bbl with a fluid displacement of 156.0±1.5 bbl and an adjusted weight per foot of 28.6±0.3 lbft.

Published: June 2024

Uterine niche is a recess located in the anterior wall of the uterine isthmus, over the cesarean section scar. This condition is often asymptomatic, but it can be associated with symptoms such as abnormal uterine bleeding, pelvic pain and secondary infertility. Endovaginal ultrasound is the first-line diagnostic method. Treatment includes hormonal methods or surgery, and surgical treatment seems to be the most effective in resolving symptoms. We describe the case of a 37-year-old woman, with an obstetric history of a pregnancy with cesarean delivery, who complained of pelvic pain and menstrual irregularity. An endovaginal ultrasound was requested, which reported the presence of a “… echogenic oval formation with well-defined limits measuring 28x17 mm in the topography of the cesarean scar.” After a clinical discussion with a doctor specializing in Gynecology, the patient was referred to a hospital consultation in this specialty for investigation. The diagnosis of uterine niche was confirmed, and the treatment consisted of the placement of an intrauterine system.
