Published: December 2024

Por su ubicación en la costa del Pacífico Sudamericano, el Perú se encuentra permanentemente expuesto al peligro sísmico. Las extendidas prácticas de construcción informal sin estándares técnicos de diseño sismo resistente, suponen una vulnerabilidad que aumenta los riesgos asociados este peligro. La presente investigación tuvo por objetivo identificar las condiciones de vulnerabilidad sísmica más frecuentes en la construcción de viviendas, empleando un método cualitativo basado en la observación visual. Se tomó una muestra de 403 viviendas del distrito del Rímac en la ciudad de Lima, Perú, en el año 2023, sin considerar la zona declarada como Patrimonio Mundial por UNESCO. Como instrumento se empleó una ficha de observación diseñada para el registro visual desde la vía pública, sin tener que acceder a las viviendas. Se concluyó que entre las principales condiciones de vulnerabilidad observadas se encuentran la ausencia de juntas sísmicas (89.33%), la diferencia de nivel de losas entre edificaciones vecinas (59.8%) y la construcción de muros de ladrillo de baja densidad (60.30%). La interacción de estas condiciones entre viviendas contiguas, puede suponer efectos catastróficos para las edificaciones y aumentar el riesgo de pérdida de vidas ante un evento sísmico, por lo cual se recomienda incidir en estos puntos en programas educativos para la población sobre la importancia de las buenas prácticas constructivas.

La investigación se enfoca en los saberes ancestrales sobre plantas nativas en la alimentación tradicional de comunidades rurales en Carazo, Nicaragua. Se busca rescatar y valorar estos conocimientos transmitidos generacionalmente, fundamentales para la sostenibilidad y la identidad cultural. Se destaca la importancia de estos saberes en un contexto de globalización que amenaza la diversidad cultural y la soberanía alimentaria. Se emplearon técnicas cualitativas como entrevistas etnográficas y talleres participativos para explorar en profundidad estos saberes. Los resultados del estudio evidencian una alarmante pérdida de identidad cultural impulsada por la globalización, mientras que algunos grupos, como los Mangue, se esfuerzan en preservar prácticas ancestrales, como el sistema agrícola de milpa, fundamental para su soberanía alimentaria. Estos hallazgos no solo destacan la urgencia de proteger la diversidad cultural, sino que también buscan impulsar la revitalización de la medicina tradicional y los sistemas alimentarios locales. A través de esta visibilización, el estudio promueve modelos alimentarios más sostenibles y resilientes, que pueden convertirse en insumos para políticas públicas orientadas al apoyo de sistemas agroecológicos y conocimientos tradicionales. La importancia del trabajo radica en su llamado a reconocer y salvaguardar los saberes ancestrales, considerándolos como patrimonio invaluable para la humanidad y pilares esenciales para construir sociedades más justas y equitativas.
La colonización del tiempo: de la imposición judeocristiana a la mercantilización capitalista
Authors: Palazio Galo Edgar 
Published: December 2024

La concepción del tiempo ha influido profundamente en la organización de las sociedades humanas. En Occidente, se concibe de manera lineal, avanzando desde el pasado hacia un futuro predeterminado. Esta visión permea la cultura, la religión y la ciencia, pero contrasta con concepciones cíclicas que existían en las sociedades precoloniales. Estas culturas, como la maya, hindú y africana, concebían el tiempo como un ciclo ligado a la naturaleza, con ritmos de renovación conectados a la vida agrícola, rituales y la cosmología. El colonialismo europeo impuso su visión lineal del tiempo, considerada como símbolo de “progreso” y utilizada para justificar la dominación sobre las sociedades consideradas “primitivas”. Esta imposición reemplazó las formas cíclicas de medir el tiempo, afectando las organizaciones sociales y espirituales de las sociedades colonizadas. A su vez, el capitalismo exacerbó esta dinámica, transformando el tiempo en una mercancía explotable y acelerando los ritmos de vida. Sin embargo, las visiones cíclicas del tiempo siguen siendo relevantes, ofreciendo una crítica al progreso occidental y proponiendo alternativas que valoran la conexión con la naturaleza y la espiritualidad. Estas perspectivas pueden ser fundamentales para desarrollar sociedades más justas y sostenibles en la actualidad. En este ensayo crítico, exploramos cómo Occidente impuso su narrativa temporal a las sociedades precoloniales y examinaremos las consecuencias de esta imposición en términos de pérdida cultural, alienación y desigualdad.

China-ASEAN Collaborative Governance of Energy Transition under the Belt and Road Initiative: Status, Challenges and Approaches
Authors: Li Yunjie 
Published: December 2024

This paper offers a comprehensive analysis of the collaborative governance practices between China and the Association of Southeast Asian Nations (ASEAN) in the realm of energy transition. It examines how the actions of Chinese energy-related entities have fostered political trust among ASEAN member states under the Belt and Road Initiative (BRI). The process of energy transition is characterized by its regional nature, high investment, and prolonged transition period. ASEAN member states have demonstrated a commitment to achieving regional energy transition, yet they are deficient in the critical elements necessary to translate proposals into actionable practices. Supported by the BRI, various spatial levels of Chinese entities have entered ASEAN to participate in cooperative governance of energy transition. The cooperation between the China-ASEAN community on the issue of energy transition has enabled an orderly and efficient progression of energy transition in Southeast Asia. Concurrently, it has bolstered the trust of ASEAN member states in China, reducing their indecisiveness in regional affairs.

Biochar was added at four levels (0, 1.5, 2, 2.5) percentage (%) by volume to the soil before planting. Planting took place on 11/23/2022. An experiment was applied in a completely randomized block design (RCBD) with three replications. The means were compared according to the Least Significant Difference (LSD) test at the probability level of >= 0.05. The percentage of chlorophyll in the plant, the efficiency of nitrogen absorption at the flowering and harvesting stages, the height of the plant, the biological yield, and the concentration of nitrogen in the plant at the flowering and harvesting stages were studied. The results of the study showed that there were significant differences when adding biochar in plant height ( A3, 107.73 Cm ) and chlorophyll content in the leaves ( A2 , 48.80 spad and A1 , 48.15 spad ) , as all treatments were superior to the control treatment. There were significant differences for adding biochar in the amount of nitrogen in the plant at the flowering ( A3 , 395 kg ha-1 ) and harvesting stage ( A3 , 250 kg ha-1 ), as all treatments outperformed on the control treatment. The results also showed that there were significant differences for adding biochar in flag leaf area ( A2 ,71.62 cm2 and A3 , 70.26 cm2 ) and the efficiency of nitrogen absorption at the flowering ( A3 , 64.4 % ) and harvesting stage ( A3 , 50 % ).
Study of saline effects in Azospirillum spp isolated from agricultural soils : south of Thi Qar governorate
Authors: Hasanain Ali Al-Kinani Hasanain Ali Al-Kinani 
Published: December 2024

Biofertilizers, containing microorganisms, colonize plant roots or interiors, increasing nutrient supply and stimulating growth. High salinity in agricultural soils reduces water absorption, growth rate, and photosynthetic activity, leading to physiological dehydration and growth inhibition. To develop biofertilizers, Azospirillum spp isolates were used, which are symbiotic nitrogen-fixing bacteria that promote plant growth, absorb minerals, and absorb water. The study aimed the impact of varying NaCl concentrations on the growth and effectiveness of Azospirillum spp isolates from five agricultural areas in the Fadliya district south of Thi Qar governorate. The isolates, all Gram-negative, were motile and responded to the requirements of biotin and pectin did not decompose during this study, except for the AZOST.3 isolate, they did not need decomposed biotin and pectin. The results of the current study showed the growth of Azospirillum spp at various levels of NaCl at a field capacity of 28% . All isolates recorded good growth at a minimum concentration of 3% NaCl, and growth gradually decreases with increasing salt concentration until reaching a concentration of 5% NaCl, which shows the extent of the portability of these isolates to grow at high concentrations of salt and its interference with humidity within the field capacity of 28%, as these isolates recorded more growth and tolerability of high salt concentrations compared to the low growth recorded by the AZO ST.1, AZO ST.2, and AZO ST.3 through a concentration of 4% NaCl at a field capacity of 14% .The study of the growth of Azospirillum spp at different pH levels also showed a variation in the growth intensity within the isolated strains of Azospirillum, as all five isolates recorded a gradual growth from the lowest level at pH 5.5 to pH 8.5 . It was also found that they can grow at high pH levels, which proves their potential as successful vaccines for cultivation in saline and alkaline soils.

Published: December 2024

This study investigated the impact of various rubber intercropping models on productivity, income, and physiological factors, compared to rubber monocropping in Tamod subdistrict, Phatthalung province, Thailand. Three intercropping models from rubber smallholder farms with mature Hevea trees were evaluated: rubber with timber trees (RT), rubber with timber and fruit trees (RTF), and rubber with timber, fruit, and shrub trees (RTFS). The rubber monoculture served as the control treatment. Data was collected from May 2021 to April 2022. Results revealed that intercropping had an 11.3% lower Tapping Panel Dryness incidence than monocropping (88.7%). The RTFS model had the highest latex yield at 1,866.31 kg/ha/year and dry rubber content at 40.11%, outperforming the other models. In the RTF model, fruit yields were 809, 92, 458, and 61 kg/ha/year for Durio zibethinus L., Lansium domesticum, Garcinia mangostana, and Nephelium lappaceum L. The RTFS model had a Salacca zalaca fruit yield of 1,220 kg/ha/year. Environmentally, the RTFS model had the lowest average temperature (30.5°C), highest humidity (68.8%), and lowest light intensity (2,955 lux) compared to the other models. Soil moisture tension was also least negative in RTFS at -5.7 kPa and -5.3 kPa at 30cm and 50cm depths. Economically, the RTF model had the highest net profit at 4,892 USD/ha/year with a benefit-cost ratio of 2.75 and a return on investment of 176%. Sensitivity analysis showed RTF maintained the highest profits even with ±10% changes in revenue and costs. Rubber intercropping, particularly the RTFS model, improved productivity, income, and environmental conditions compared to monocropping.
Production of red palm oil and red palm fats by vacuum frying sterilization and multi-step fractionation

Published: December 2024

The question on health impact of the refining palm oil has driven the oil palm producers in Thailand toward developing the wellness products that are in high demand in the future. Red palm oil (RPO) which is rich in carotenoids and vitamin E catches attention. However, production of RPO by the current steam sterilization method has negative impact on environment and requires high capital investment, while the cost-saving dry sterilization method delivers a low-quality product. To develop the effective RPO processing method suitable for the small and medium-size enterprises (SMEs), the vacuum frying method was studied. The whole production steps consist of vacuum frying sterilization, acid degumming, neutralization, and then multi-step fractionation. The steam sterilization method was compared by using the same arrangement step except the sterilizing procedure. Sterilization by the vacuum fryer was controlled at 80 °C, -400 to -720 mmHg. Results showed that the optimal vacuum frying time was 90 min. The fractionation temperatures of the vacuum frying method were 34 °C, 27 °C and 17 °C, whereas those of the steam sterilized method were 34 °C, 25 °C and 15 °C. Quality of RPOs produced from both methods were within the edible oil standard. The vacuum frying method produced the RPO with 0.17% free fatty acids, 6.65 meq.O2/kg peroxide value, 620 mg/kg carotenoids, 835 mg/kg vitamin E and 61.31% yield. The main advantage in term of quality of the vacuum frying method lies mainly in improving yield and oil odor, which is a sensory characteristic that play an important role in consumer acceptance of the product. The red palm fats obtained from the multi-step fractionation provided a wide range of fats suitable for different applications. Therefore, the vacuum frying could be regarded as the sustainable process technology appropriated for the SMEs.
