Authors: Ramírez Carmen , Fernández Roxana , Ostojich Zoitza , Arraiz Issis , Balbuena José , Quintero Liandry , Zerpa Sandra
Published: May 2024

El Saní o semilla de la planta del nabo (Brassica spp.), es una especia típica del páramo merideño, conocida localmente como “la mostaza negra del páramo”; en el pasado, era frecuentemente consumida previo tostado y molienda como acompañante de las comidas. Aunque es un alimento de fácil acceso y elaboración para la población del páramo, actualmente es poco consumido debido, en gran parte, al desconocimiento de sus propiedades nutricionales, pues hay muy poca información científica disponible sobre ella. Por esta razón, el objetivo principal de la investigación fue determinar la composición proximal del Saní y considerar su posible aplicación en la gastronomía. Las semillas se recolectaron en el Páramo de Mucuchíes, específicamente en la comunidad de Misintá, Municipio Rangel, estado Mérida. A través del análisis proximal se determinó que el Saní tiene un contenido de proteínas de 19% y 30% de grasa. Se evaluó el tiempo de tostado y se encontró que para disminuir su regusto amargo, debe tostarse por un máximo de 10 minutos, ya que tiempos más altos acentúan su amargor. Se elaboraron diferentes recetas con la adición de Saní como un ingrediente. Por último, se elaboró una página web que pretende promover el uso frecuente del Saní en la dieta de los merideños.

The response of Pacific decadal variability to global warming
Authors: Wang Jingyi
Published: May 2024

Pacific Decadal Variability (PDV) plays a pivotal role in understanding climate shifts. This study focuses on investigating the primary components of PDV, namely, the Pacific Decadal Oscillation (PDO) and the North Pacific Gyre Oscillation (NPGO). These components are defined as the first and second principal modes of the North Pacific sea surface temperature anomaly field. Our analysis indicates that under the influence of global warming, both PDO and NPGO exhibit a weakening of the amplitude and a shortening of the period. Furthermore, NPGO demonstrates a more pronounced response to a 2C warming scenario compared to a 1.5C increase. This heightened sensitivity is attributed to the accelerated propagation of Rossby waves, a consequence of enhanced ocean stratification. The findings of this research contribute to the establishment of a scientific foundation for informed environmental policy development, facilitating the promotion of environmental conservation and sustainable development.

Authors: Xia Jingxi
Published: May 2024

Winglets are structures with unique shapes designed on the wingtips of aircraft. They were first time justified as a device that can improve aircraft fuel efficiency by generating more lift in the last century and have been widely used in the aviation industry until today. The current winglets installed on jetliners, however, are fixed, resulting in that winglets can only be aerodynamically optimized for single flight condition. Searching for further improvement on flight performance, this paper investigates and analyzes two types of morphing winglets that can adjust their configurations during flight for aerodynamic optimizations under multiple conditions. Three computational studies based on three current business jets, representing aerodynamic characteristics of typical jetliners, are referenced. The studies results are presented and categorized into different flight phases, and the flight performance is embodied in terms of aircraft maximum climb rate, lift-to-drag ratio, and cruise fuel flow rate. Finally, the overall performance gained and the feasibility of implementation are evaluated.

The impact of interest rate uncertainty on renewable energy investments: Compared with conventional energy investments
Authors: Chen Yanjie
Published: May 2024

In contrast to other types of energy investments, governments often use long-term power purchase agreements (PPAs), subsidy policies, etc., to lock in returns on renewable energy investments. To some extent, these initiatives ensure that renewable energy investment has a fixed future cash flow. The publics demand for an increase in the proportion of renewable energy also forces the government to maintain an annual investment in renewable energy. However, it remains uncertain whether peoples willingness to invest would not be severely affected, and whether renewable energy investment volumes are uniquely robust in the face of financial uncertainty. In this paper, linear regression method is used to analyse the impact of short-term interest rate uncertainty on renewable/conventional energy investment, and covariance analysis is used to test whether these impacts are significantly different. The data indicate that short-term interest rate uncertainty has a significant negative impact. Investment in both types of energy shrinks rapidly in the face of high interest rate uncertainty. No obvious stability is found on renewable energy investment volume in the face of short-term interest rate uncertainty.

Remote sensing monitoring and application research on the "Non Grain" cultivated land of arable lands in the Nandu River Basin
Authors: Wen Chengju
Published: May 2024

In recent years, China has attached importance to food production and food security. However, in certain regions where oversight has been relaxed, there is a tendency for arable lands dedicated to grain cultivation to be repurposed for other uses. The conversion of such land leads to a decline in grain output. This is not in line with Chinas policies that intended to ensure food security. Traditional manual monitoring to address these concerns is time-consuming and labor-intensive. Remote sensing, as an emerging technology, can play a significant role in monitoring arable lands. In this study, we utilized multi-seasonal remote sensing images to extract information on arable lands and other regions on both sides of the Nandu River Basin. The analysis revealed that are large areas along the banks of the Nandu River are utilized for double-cropping rice cultivation. However, there are also patches of land that might be used for non-grain purposes, and some suspicious patterns were also observed. This study further explored the advantages and potential of remote sensing as an emerging technology for monitoring arable lands. And it also delves into the limitations of this technology, as well as its interdisciplinary integration.

Authors: Deng Dongni
Published: May 2024

In the study of nutrient cycling in forest ecosystems, traditional methods are increasingly unable to meet the researchers need for understanding the mechanisms of nutrient cycling. Stable hydrogen and oxygen isotope tracing techniques have become important methods for studying the mechanisms of nutrient cycling in forest ecosystems due to their high sensitivity and tracing capabilities. Scholars from both domestic and international backgrounds have conducted research on nutrient cycling in forest ecosystems from various time scales and hierarchical levels. Based on a brief introduction of the principles of hydrogen and oxygen isotope tracing, this paper systematically elaborates on the use of stable 15N isotope dilution techniques and tracing techniques to determine the conversion rate of total N in forest soils and the 15N recovery rate. This aims to reveal the transport and transformation laws and retention mechanisms of forest soil 15N, especially inorganic N. By utilizing stable isotope tracing, isotope ratio mass spectrometry analysis, and other techniques, research on biological nitrogen fixation has been conducted, including the measurement of biological nitrogen fixation, the study of nitrogen fixation mechanisms, and the identification of new nitrogen-fixing species. Isotope labeling, as a key technical means for exploring the biological world, can trace chemical reactions within microbial organisms and their influencing factors. It aims to lay a scientific foundation for further exploration of nutrient cycling in forest ecosystems, especially processes related to nitrogen cycling. Additionally, it provides basic data and theoretical basis for the protection, restoration, and sustainable management of forest ecosystems.

Authors: Quesada Coronado Daniela
Published: May 2024

El uso de anticonceptivos orales a nivel mundial aumentó en un 151% en un período de 25 años (1994-2019). Debido a esto, cualquier efecto ocasionado en la salud por las mismas pueden tener consecuencias considerables en la salud pública general. Este estudio analizó la relación entre el consumo de anticonceptivos orales y la presencia de indicadores de depresión en mujeres costarricenses en edad reproductiva. Se utilizó como instrumento una adaptación del BDI-II y preguntas adicionales sociodemográficas. La recolección fue presencial durante el mes de abril 2023 y el muestreo fue a conveniencia. Participaron 206 mujeres entre los 18 y 49 años (M=28.29, DE=7.37), y aunque no se encontró una relación significativa entre el uso de anticonceptivos orales y la depresión, se observó un ligero aumento en los indicadores de depresión entre las mujeres que los consumían.  Se encontró también una correlación inversa entre el puntaje de la escala BDI-II y el tiempo de consumo (r=-.26, p= .02), lo que significa que, a mayores indicadores de depresión, menor el tiempo de consumo. Así como una correlación con un nivel mayor de depresión y menor edad de la mujer (r=-.29, p= “001”). A pesar de los beneficios de los anticonceptivos orales, como la prevención del embarazo y el alivio de síntomas relacionados con la menstruación, existen efectos secundarios y preocupaciones sobre la salud mental en la literatura. Aunque esta investigación no reveló diferencias estadísticamente significativas, los hallazgos sugieren un patrón que enfatiza la necesidad de una exploración más exhaustiva en este ámbito.

The development of the country and care for its population, along with the growing demand for Armenian honey abroad, require compliance with increasingly stringent safety and quality standards for this product. Based on the detection of residues of contaminants in Armenian honey, researchers from CENS are concerned about the potential risk to consumers. Besides the health risk to consumers, the presence of contaminations in honey could have a negative impact on the export of the product and its contribution to the country’s economy. The article analyzed data from tested samples of Armenian honey for the presence of nitrofuran metabolite residues. According to the test results, out of the four metabolites, only one metabolite, 1-aminoguanidine (AHD), was detected in the honey samples. To assess the risk, the Margin of Exposure (MOE) method and the formation of homogeneous consumer clusters were used, considering different daily honey consumption levels and gender of consumers. Also, the worst-case scenario was considered, simulating an increase in the daily consumption of honey with a maximum concentration of AHD. The results showed safe MOE values for all consumer groups, indicating no concerns associated with nitrofuran exposure. Moreover, the worst-case scenario demonstrates the possibility of increasing the daily consumption of honey without harmful effects on the consumers. Nevertheless, the presence of contaminant in honey is a cause for concern.

Развитие страны и забота о ее населении, а также растущий спрос на армянский мёд за рубежом вызывают необходимость соответствия всё более строгим требованиям безопасности и качества этого продукта. На основании случаев обнаружения остатков загрязняющих веществ в армянском мёде исследователи обеспокоены возможным наличием риска для потребителей. Кроме риска здоровью потребителей, наличие контаминаций в мёде может негативно сказаться на экспорте продукта и его вкладе в экономику страны.

Bu çalışma, sosyal medyanın tüketicilerin yeşil tüketim algılarını nasıl etkilediğini anlamak için kapsamlı bir metin madenciliği uygulaması gerçekleştirmektedir. COVID-19 salgını, toplumun insan ve doğanın nasıl etkileşime girdiğine daha fazla dikkat etmesine neden olmuştur. Yeşil tüketiciliği teşvik etmek, sürdürülebilir kalkınma hedeflerine ulaşmak için gereklidir; bu da kamuoyunun sürdürülebilirlik algısını anlama ve değiştirme becerisini gerektirir. Önceki araştırmalar, yeşil tüketimi incelemek için davranışsal modeller ve anketler kullanmıştır, ancak bunlar genellikle sosyal medyanın bakış açısını göz ardı etmiştir. Bu çalışma, müşteri davranışları ve tercihleri hakkında içgörüler elde etmek için sosyal medyadaki metin ve video içeriğini analiz etmek için metin madenciliği algoritmaları kullanmaktadır. Bu çalışmada Twitter ve YouTube'dan veri toplanarak metin sınıflandırma için metin madenciliği algoritmaları uygulanmıştır. Sonuç olarak bu çalışma, sosyal medyada yer alan metin ve video içeriklerini analiz ederek tüketicilerin yeşil tüketim algılarını nasıl etkilediğini anlamak amacıyla metin madenciliği uygulamaları kullanmaktadır. Elde edilen bulgular, sosyal medyanın tüketici davranışları ve tercihleri üzerindeki etkisine ilişkin önemli içgörüler sunmaktadır.
NĂNG LƯỢNG VÀ HỆ SỐ NGHỊCH TỪ CHO EXCITON TRONG ĐƠN LỚP WSe2

Exciton hai chiều trong đơn lớp TMDC (transition-metal dichalcogenides) đặt trong từ trường đều là một bài toán hấp dẫn đối với nghiên cứu thực nghiệm lẫn lý thuyết trong thập kỷ vừa qua do có tính ứng dụng cao trong các thiết bị quang-điện tử. Đặc biệt hệ số nghịch từ của exciton trong đơn lớp TMDC nhận được nhiều sự quan tâm, cụ thể là đơn lớp Wse2 được kẹp bởi boron nitride (h-BN). Tuy nhiên sự chênh lệch giữa các tính toán lý thuyết và đo đạc thực nghiệm đối với các đại lượng của vật liệu đòi hỏi cần phải có nhiều sự cải tiến về mặt lý thuyết. Trong công trình này, chúng tôi sử dụng phương pháp nhiễu loạn có điều tiết bằng cách kết hợp lý thuyết nhiễu loạn Rayleigh-Schrӧdinger cùng với phép biến đổi Levi-Civita và thêm vào một tham số tự do. Phương pháp này có lợi thế trong việc xác định hệ số nghịch từ exciton ở gần đúng bậc hai. Các kết quả hệ số nghịch từ thu được cho thấy sự phù hợp tốt với các công trình hiện nay.
