Authors: Marroquín Morales Pablo , Jiménez Pérez Javier , Yerena Yamallel José Israel , Sandoval García Rufino
Published: March 2024

La acumulación de carbono en el café es una forma de disminuir los gases de efecto invernadero y combatir el cambio climático; sin embargo, en la Sierra de Chiapas no se tiene información precisa sobre la captura de carbono en los cafetales. Cuantificar el carbono es dispensable para valorar este servicio ecosistémico y conservar las plantaciones de café a través de subsidios. Por esta razón la presente investigación tiene como objetivo, evaluar el carbono almacenado en biomasa aérea de café en dos gradientes altitudinales, así también determinar la concentración de carbono (CC) y nitrógeno, siendo la CC un elemento indispensable para obtener el carbono almacenado en café. El estudio se realizó en dos altitudes: la primera a 1 200 m y la segunda a una altitud de 1 500 m. Para estimar el carbono, primeramente, se estimó la biomasa de manera indirecta utilizando una ecuación alométrica para la especie, posteriormente la concentración de carbono y nitrógeno se determinó con un equipo denominado analizador elemental Thermo Scientific Flash 2000 NC Soils Analyzer, que funciona por combustión completa a 950 °C. Una vez obtenido la biomasa y la concentración de carbono en café se multiplicaron, obteniendo así el carbono almacenado, para el dióxido de carbono se multiplicó el carbono almacenado por la constante 3.67. Los resultados indican diferencias significativas en el rango 1 200 msnm (10.72 t C ha-1) y el más bajo almacenamiento de carbono en el rango 1 500 msnm (4. 74 t C ha-1). Lo anterior, indica que la captura de carbono en café es influenciada por la altitud del sitio, a menor altitud mayor carbono almacenado habrá en el café.
“Thyroid”: Letter to the Editor, Radioactive Iodine: A Living History
Authors: Barbara Hertz
Published: March 2024

The history of the origin of the medical uses of Radioiodine (RAI) has been compromised by false narratives as recently as June 2023 in the “Thyroid “article “Radioactive Iodine: A Living History”. Primary sources document Dr. Saul Hertz (1905 - 1950) as solely conceiving of the medical uses of RAI, being the first and foremost to develop the experimental data, bringing RAI from bench to bedside, and extending the use of radionuclides to diagnose and/or treat cancer and other conditions. Dr Hertz predicted and worked toward conquering cancer with other radionuclides. Saul Hertz overcame the racism of his time, a world war interrupting his first clinical study, a strong pushback from the surgeons, and unethical medical publishing practices. Today, Nuclear Medicine, Radiopharmacy, Medical Physics, and other specialties are collaborating and actively building on Saul Hertz’s enduring foundational work.

Published: March 2024

Abstract. To improve the oleophilic and hydrophobic properties of two different types of polyurethane sponge (flexible, FPU, and rigid, RPU) for oil spill cleanup, acrylamido phenyl chalcone palamitamid, a recently synthesized monomer with long chains of linear alkyl groups, was in situ crosslinked with divinylbenzene. Grafted PU cubes were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The water sorption of ungrafted FPU and RPU decreased from 18.05 and 15.66 to 7.31 and 7.06 for grafted FPU and RPU, respectively. The effect of oil type on the sorption capacity testing was explored and compared using crude oil, diesel fuel, and water-oil systems. It was found that the crude oil and diesel fuel sorption of grafted FPU and RPU cubes was increased compared with ungrafted FPU and RPU cubes, and the maximum values for adsorption were recorded using crude oil. These results can be explained by increasing the adherent forces between the adsorbent and the oil surface with increasing oil viscosity, and consequently, the oil adsorption increases. The high oil absorption capacity is mainly attributed to the high porosity of the sponges. The modified FPU and RPU cubes can be effectively used in oil and water spill cleanup.
 
Resumen. Para mejorar las propiedades oleófilica e hidrofóbica de dos tipos diferentes de esponjas de poliuretano (flexible, FPU y rígida, RPU) para la limpieza de derrames de petróleo, se llevó a cabo una reacción de entrecruzamiento in situ con divinilbenceno a partir de acrilamido fenil chalcona palamitamida, un monómero recientemente sintetizado y que contiene cadenas largas de grupos alquilo lineales. Los cubos de PU injertados se caracterizaron mediante espectroscopía infrarroja por transformada de Fourier (FTIR) y microscopía electrónica de barrido (SEM). La sorción de agua de FPU y RPU no injertadas disminuyó desde 18,05 y 15,66 hasta 7,31 y 7,06 para FPU y RPU injertados, respectivamente. Se exploró y comparó el efecto del tipo de petróleo en las pruebas de capacidad de sorción, utilizando petróleo crudo, combustible diesel y mezcla agua-petróleo. Se encontró que la sorción de petróleo crudo y combustible diesel de los cubos de FPU y RPU injertados aumentó en comparación con los cubos de FPU y RPU no injertados, obteniéndose los valores máximos de adsorción para el caso de petróleo crudo. Estos resultados pueden explicarse en base al aumento de las fuerzas de adherencia entre el adsorbente y la superficie del aceite al aumentar la viscosidad del aceite, y como consecuencia la adsorción del aceite aumenta. La alta capacidad de absorción de aceite se atribuye principalmente a la alta porosidad de las esponjas. Los cubos FPU y RPU modificados se pueden utilizar eficazmente en la limpieza de derrames de petróleo y agua.

The Griffin and Lion Ivory Pyxis Lid from the Grave of the Griffin Warrior at Pylos
Authors: Davis Jack L. , Stocker Sharon R. , Aruz Joan
Published: March 2024

ABSTRACT: In 2015, an exquisite ivory pyxis lid was discovered in the grave of the Griffin Warrior at Pylos. The lid, carved in high relief, depicts in great detail a combat in which a lion defeats a griffin. The modeling and carving of the ivory are of exceptional quality. Here, we first consider the specific context and circumstances of discovery of the lid—the final find removed from the grave—before turning to a discussion of precedents and parallels for its motifs and theme. Finally, we consider the possibility that a scene of a lion victorious over a griffin had particular significance at Pylos, in light of relations between Messenia and Neopalatial Crete in the Late Helladic IIA period.

Published: March 2024

ABSTRACT: The Western Argolid Regional Project (WARP) is an intensive pedestrian survey of 30 km2, located northwest of Argos along the banks of the Inachos River. Using high-intensity collection strategies, WARP generated very fine-resolution data that provide insights into the ways this seemingly marginal area contributed to and was impacted by regional histories. A key question is how the network of mountainous routes that traverse this landscape, connecting the area to the Corinthia and Arkadia, may have influenced localized, diachronic settlement patterns. This article focuses on areas of high artifact densities to demonstrate how regional activity and interconnectivity changed from the Neolithic to Modern period at this crossroads in the northeastern Peloponnese.

Published: March 2024

In today's globalized world, the importance of language learning is paramount due to factors such as international travel, work opportunities, and cultural exchange. Accurately assessing language proficiency and placing learners in appropriate courses is crucial to maximize the benefits of language education. Language placement tests serve this purpose by determining learners' starting points based on their language skills, ensuring they are appropriately challenged and motivated. These tests are widely used in educational institutions and typically cover various language skills like grammar, vocabulary, reading, writing, speaking, and listening. By placing students at the right level, language placement tests enable instructors to tailor lessons to their individual needs, fostering growth and engagement. The integration of reliable placement tests has become indispensable in language education to provide fair assessment, effective instruction, and successful language acquisition. In this article, we present the results of a survey on the reliability of placement tests from the students’ perspective. The quantitative and qualitative study with 120 respondents was conducted in the spring semester of 2023 at Vytautas Magnus University. The study aimed to explore whether the participants believed that placement tests accurately gauge their actual language knowledge and skills and if VMU English Placement Test accurately identifies suitable language proficiency levels for students. The study also sought to collect data for recommendations to improve VMU English Placement Test. According to the respondents, VMU English Placement Test efficiently determines the test takers’ language proficiency levels. Nevertheless, a definitive answer to the question of whether English placement tests reliably indicate actual English language proficiency remains open, as the responses split evenly into positive and negative viewpoints. The study also revealed that all facets of English language competence, including writing, reading, grammar, and listening, must undergo assessment through placement tests.

Published: March 2024

Health promotion is related, in all people, to factors such as physical health, stress, mental clarity, financial status, mental resilience and social support. Undiagnosed adults with autism elements, compared to the rest of the population, are at greater risk of depression, anxiety disorders, mood disorders, and obsessive-compulsive disorders. These individuals often become dysfunctional in professional, social and family contexts, they also feel social and emotional dissatisfaction without even knowing the cause of their problems. The detection of autistic elements of adults is necessary for health promotion so that they receive appropriate support from health professionals, and to prevent serious mental, physical and mental health problems. The scope of this research through the systemic bibliographic review is the recognition of autistic elements diagnostic tools in adult population. There have been 14 trustworthy measuring tools for autistic elements. 12 of which are self- referential tools, one tool that requires a specialist to yield result and one diagnostic tool. The trustworthiness and the validity of all tools are above 0,70 rendering them both trustworthy and valid to be used. The results of the bibliographic review have proven that the majority of the tools rely on the measurement of social skills deficiencies, empathy levels and sensory dysfunctions of the respective adult population sample.

Published: March 2024

This study aimed to analyze the concentration of %HSU (Heavy Smoke Unit) in the exhaust emissions of freight trucks in Manokwari Regency. It employed a quantitative research approach and utilized incidental sampling to select a total of 30 vehicles as samples. To examine the relationship between exhaust emissions and vehicle characteristics, linear regression analysis was employed. Out of the 14 vehicles (46.67%) that failed the emission test, only 2 (14.29%) were produced before 2010, while the production of the remaining 12 (85.76%) was after 2010. Simultaneously, Cylinder Capacity (X₁), Trip Length (X₂), Vehicle Age (X₃), and Vehicle Maintenance (X₄) influenced the %HSU value (Y). This was indicated by the very small p-value (0.000), where the mean differences between the groups were highly statistically significant. The results showed that the independent variables were mutually related and collectively have a significant impact on the %HSU value.
