Published: June 2024

La sostenibilidad organizacional de las asociaciones agroecológicas representa un problema latente que limita el desarrollo social y sostenible de sus comunidades, constituyéndose en una preocupación pública que requiere de la intervención permanente de instituciones gubernamentales y no gubernamentales para el fortalecimiento de su estructura organizativa. Es así que, resulta indispensable analizar los elementos organizacionales que aportan a la sostenibilidad de las asociaciones agroecológicas, en casos de estudio exitosos, en la provincia del Azuay. Para ello, se recurre a una metodología cualitativa-participativa. Los resultados muestran que la planificación estratégica resulta fundamental para el funcionamiento de las asociaciones. Los recursos son un elemento esencial para la gestión administrativa y productiva. La comercialización requiere de articulación con otras redes de comercialización a nivel provincial, sin embargo, la cultura organizacional se constituye en el eje central de su sostenibilidad, pues, influye en sus valores, prácticas, interacciones, define su identidad y sentido de pertenencia y fortalece su compromiso con principios agroecológicos, la preservación del medio ambiente, la equidad social y la solidaridad. En estas organizaciones la sostenibilidad reside en la planificación estratégica, recursos financieros y materiales, tecnología y comercialización.

Published: June 2024

Duckweeds, recognized as the fastest growing aquatic flowering plants, exhibit substantial biomass production. Recently, they have been emerged as a potential industrial crop for efficient and eco-friendly protein production and nutrient recovery compared to conventional crops. The objective of the study was to determine the biomass accumulation rate, protein content and amino acid analysis of duckweeds (Lemna minor D0158).We cultured L. minor D0158 from its preserved state in the gene bank into both aseptic (in-vitro) and open condition at controlled room. The medium was Hoagland Solution (HS) mixed with sucrose in in-vitro condition while 1/5 concentration of HS (without sucrose) was in the open condition. Subsequently, we determined the dry biomass growth by calculating the weight difference adopting the Bergmann Method, and then calculated the protein percentage following the Kjeldahl Method. Moreover, the amino acid profiling was obtained using the Hydrolysis and Liquid Chromatography Technique. Later on, we compared the results with those of the other duckweeds and soybean together with the FAO requirements. We found that L. minor D0158 possessed the dry biomass growth rate of 6.72 g/m2/d with 33.13% protein content within 7-day cultivation period. Moreover, it exhibited significantly higher levels of branched chain amino acids (BCCAs) than soybean and met the FAO requirements. However, methionine (Met) content was found to be slightly low. The study suggested that L. minor D0158 might offer a sustainable solution for protein food security in future.

Published: June 2024

Ornamental plants (OPs) are beneficial to remove, control and reduce heavy metals (HMs) in a process called 'phytoremediation'. This study evaluated the in vitro system-based phytoremediation properties of Tagetes erecta and Gomphrena globosa calli. Leaves from in vitro seed-grown T. erecta and G. globosa were used as an explant source for callus culture. Callus culture was found optimal in MS medium supplemented with 8 μM BAP + NAA for T. erecta and 2 μ M 2, 4-D for G. globosa. These plants were grown in their respective optimized (controlled) medium enriched with different amounts (50, 100, 150, 200, and 250 μM) of Cadmium (Cd) added in the form of Cadmium chloride (CdCl2). The in vitro calli developed were evaluated for Cd stress tolerance based on callus diameter, growth tolerance index (GTI) and catalase (CAT) activity. Over four weeks, the callus diameters of T. erecta and G. globosa grown in different concentrations of Cd had lower growth than that of the controlled one. On the other hand, the GTI measured were greatest at 150 μM of Cd for both T. erecta (130.95%) and G. globosa (149.32%) suggesting a potential Cd tolerance. However, the CAT activity in T. erecta callus increased with the Cd concentration peaking at 150 µM then started declining while G. globosa callus showed the highest CAT activity at 50 μM of Cd. Thus, T. erecta callus showed greater Cd tolerance with the prospect of utilizing it for phytoremediation. The study also suggests growing T. erecta at 150 μM Cd for tolerant calli.

Published: June 2024

Urban Forestry is an integral component of sustainable urban development, involving strategic administration of trees and green areas within urban environments. In this dynamic domain, institutional engagement is closely connected with local governments, sub-metropolitan offices, and division forest offices playing crucial roles in shaping policies and regulations. The significance of public perception in urban forestry practices cannot be overstated, as it shapes community involvement and endorsement for initiatives focused on improving environmental quality and urban well-being.  The research aims to look into the public perception and institutional involvement in the development of urban forestry in Dhangadhi Sub-Metropolitan City, Sudurpaschim Province, Nepal. It seeks to assess the awareness levels of the residents regarding urban forestry initiatives and understand their perceived benefits and concerns. Simultaneously, the study will analyze the specific roles played by key institutions, including sub-metropolitan offices and division forest offices, in shaping urban forestry within the region. This paper is based on a household survey (n=210) and key informant interviews (n=7) representing the different institutions related to urban forestry. Roadside plantations, park and avenue plantations, as well as community forest management, were the major activities under urban forestry. Regarding the people’s perception, the majority of the respondents (80%) were found to be aware of the advantages associated with urban forestry however only 35% of people were found engaged in urban forestry activities. Over the past few years, the local government has advocated for urban greenery. Despite these efforts, there is a lack of corresponding legislation or regulations specifically addressing urban forestry. Consequently, the effective management of city forestry demands concrete scientific and professional expertise.

Published: June 2024

In recent years, the tourism industry has witnessed significant growth, resulting in an increased demand for effective and personalized tourist place recommendation systems. In this study, a tourist spot recommendation system is proposed which is built by developing a machine learning model based on a Support Vector Machine (SVM), Decision Tree (DT), and k-Nearest Neighbors(k-NN). Public experiences and opinions regarding the various spots available in popular social media sites such as TripAdvisor, Google, Instagram, and TikTok are utilized to train the model. The system matches the probability of the user query with the predicted probability of reviews for a particular spot. The SVM algorithm, known for its robustness in handling high-dimensional data, is adapted to model the complex relationships between users' reviews, spots, and their attributes. Real-world data is used to evaluate the system's performance, demonstrating its ability to significantly improve the user experience and contribute to the sustainable growth of the tourism sector. The system's capability was demonstrated as it achieved a notable F1-Score of 0.78 when SVM was implemented. Additionally, a promising accuracy rate of 93.023% was observed when random queries were used for tourism spot prediction, emphasizing that SVM outperformed DT and k-NN.

Authors: Thapa Ishwor , Devkota Bidur
Published: June 2024

Air pollution, particularly fine Particulate Matter (PM 2.5), poses significant health risks and environmental challenges worldwide. Therefore, it is essential to monitor air pollution to act on it. In this study, PM 2.5 was estimated using meteorological data and Sentinel-5P air pollution data using machine learning algorithms. The Sentinel-5P data are   and the meteorological data utilized are air temperature, Relative Humidity (RH), and Wind Speed (WS). The three Air Quality Monitoring (AQM) stations in Kathmandu, Nepal, were chosen as a study area for this research. The effectiveness of several machine learning methods, such as K-Nearest Neighbors (KNN), Support Vector Machine (SVM), eXtreme Gradient Boosting (XGBoost), and Random Forest (RF), were evaluated. Both RF and XGBoost consistently performed better than SVM and KNN in terms of PM 2.5 estimation accuracy. RF got the highest R2 value of 0.80 and SVM with the lowest R2 value of 0.62 in the Sentinel-5P dataset only. The addition of meteorological data further improved the model's performance. After including metrological data in Sentinel-5P data the RF demonstrated the maximum R2 score of 0.816 and XGBoost with R2 score of 0.814. Hence, this study demonstrated machine learning algorithms can be used to estimate PM 2.5 by utilizing satellite and meteorological data, providing important information for air quality monitoring and management.

Authors: Bhat Samir Ali Roy , Bhandari Shraddha , Bastakoti Durga
Published: June 2024

The value of air pressure in the tire not only supports the entire weight of the vehicle, it also plays a crucial role in improving the vehicle’s performance, reducing friction, providing comfort, boosting economy and enhancing safety. This study deals with the influence of tire inflation pressure on fuel consumption at various road conditions and speeds. The experimental test was performed riding a motorcycle of 180cc and using a mileage measuring kit to find the effect of tire pressure on three different road surfaces i.e., highway, earthen and graveled. The standard tire pressure for both front and rear tires recommended by the manufacturing company was also evaluated to observe the change in mileage. The results showed that the highest mileage of 55.97 km/L was obtained on the highway among the defined three road conditions and a linear drop of 5psi in tire pressure led to loss of mileage up to 6.11% in highway, 5.35% in earthen and 2.80% in graveled road. Also, the variation in speed resulted to compensation of mileage by nearly 39.9% maximum. These results highlight the importance of keeping the correct value of tire inflation pressure in relation to fuel consumption.
Computational Evaluation of Pulsating Heat Pipe for Fluid Flow Behavior and its Thermal Performance
Authors: Badu Prakash , Guragain Kushal , Bastakoti Durga
Published: June 2024

Computational fluid analysis of a single circuit heat pipe was undertaken to ascertain the thermal efficiency of water at various fill ratios, specifically 40%, 50%, and 60% under varying heating conditions. The analysis employed the ANSYS Fluent computational fluid dynamics software, utilizing a k-epsilon to the heat pipe as the solver. The analysis was carried out on a copper tube with an internal diameter measuring 3/16 inches. During the analysis, the thermal inflow at the adiabatic region was adjusted to zero, while the condenser region’s temperature remained constant at 25°C. Meanwhile, the heat input at the evaporator region was systematically adjusted to 105°C, 110°C, 115°C, and 120°C. Key Performance characteristics of heat pipe i.e. thermal resistance, and water volume fraction were evaluated during analysis. The temperature variations noted in both regions affirmed that the pulsating pipe’s performance was influenced by the phase transition between liquid and vapor. Furthermore, the concentration of volume within the evaporator section was monitored, confirming the presence of a dual-phase phenomenon within the heat pipe. Through the analysis, it was noted that the thermal resistance of the water is minimized at a 50% fill ratio for each level of heat input. Notably, the promising results were obtained at an input temperature of 120°C with a value of 1.025°C /W which was 7.3% and 9.8% lower than thermal resistance at 40% and 60% fill ratios, respectively. The reduced thermal resistance in this scenario is attributed to the flow dynamics within the capillary, propelled by rapid phase change mechanisms. This shows the importance of Pulsating Heat Pipes (PHPs) in thermal control, as well as the intricacies of their operating mechanisms. Experimental and theoretical investigations have investigated numerous elements influencing PHP performance, with numerical modeling providing insight into thermal resistance and water volume fraction dynamics under varying heating temperatures and fill ratios.

THE GERMAN STUDENT MOVEMENT AND THE LITERARY IMAGINATION
Authors: Rinner Susanne
Published: June 2024

Through a close reading of novels by Ulrike Kolb, Irmtraud Morgner, Emine Sevgi Özdamar, Bernhard Schlink, Peter Schneider, and Uwe Timm, this book traces the cultural memory of the 1960s student movement in German fiction, revealing layers of remembering and forgetting that go beyond conventional boundaries of time and space. These novels engage this contestation by constructing a palimpsest of memories that reshape readers’ understanding of the 1960s with respect to the end of the Cold War, the legacy of the Third Reich, and the Holocaust. Topographically, these novels refute assertions that East Germans were isolated from the political upheaval that took place in the late 1960s and 1970s. Through their aesthetic appropriations and subversions, these multicultural contributions challenge conventional understandings of German identity and at the same time lay down claims of belonging within a German society that is more openly diverse than ever before.
Global Competency Integration in STEAM Fields in Higher Education
Authors: Bushey Lori Jean
Published: June 2024

The concept of Global Competency (GC) has a growing presence in many collegiate mission statements in the United States. This interconnected, multidisciplinary approach coincides with that of the concept of Science, Technology, Engineering, Arts, and Mathematics (STEAM) education. The focus of this study was to identify what extent GC is present in the classrooms and curriculums, as well as the implementation methods higher education instructors observe and / or utilize in their STEAM field programs. The participants in this study were STEAM-field instructors at higher education institutions in the United States in which GC or an equivalent term is located in their mission or strategic plan. Seventy-six instructors from the midwestern United States completed a survey to generate a GC integration score, and 13 of those also participated in an interview. The quantitative analysis identified a statistically significant difference between the integration scores of Arts and Science instructors and Arts and Engineering instructors. Qualitative analysis identified curriculum and instruction-based strategies of successful integration, common barriers to integration, and the sentiment that integration varies greatly from a regional and sometimes institution-wide setting. The findings of this study can help standardize the concept and integration of GC in higher education as well as provide curriculum developers and administrators with a look at how GC is represented in the current climate of higher education.

Published: June 2024

The article describes the results of studies on the impulse activity of various groups of afferent fibers and EMG patterns of lower leg antagonist muscles when walking without, during and after transcutaneous electrical stimulation of the dorsal roots of the lower thoracic spinal cord of a person. Using a mathematical model based on the prediction of the triggering of muscle spindles, variability in the manifestation of impulse activity of various afferents tibialis anterior muscle (TA) and gastrocnemius medialis muscle (GM) when walking under different experimental conditions is shown. It was found that walking on a movable treadmill tape in the absence of spinal cord stimulation was accompanied by strong impulse activity of afferents I (Ia and Ib) and II groups GM, increased excitability of its motorneuron pool and weakening of afferent activity and excitability of TA. On the contrary, electrical stimulation of the spinal cord during walking caused strong impulsive activity of group II TA afferents and moderate — GM, while the activity of Ia fibers TA and GM decreased to moderate impulsivity, Ib afferents of the same muscles had the weakest activity, and the excitability of the GM motorneuron pool was greater than TA. During the postactivation period, walking was accompanied by increased impulses of afferent fibers of group Ib and II GM, weakening of afferent flows of Ib TA and Ia afferents GM, but along with this, afferent signals of group Ia and II to the motorneuron nucleus TA decreased to moderate impulses, and excitability of the motorneuron pool GM was higher than TA. The supposed reflex mechanisms of locomotion regulation are discussed on the basis of well-known phenomena associated with the interaction of various afferent inputs to the spinal cord neuronal apparatus in the system of lower leg antagonist muscles.

Published: June 2024

We studied the influence of breathing exercises (BE) with an imposed rhythm on the dynamics of heart rate variability (HRV) parameters in order to study the nature of adaptive processes in the body of girls with different initial levels of total HRV. Heart rate, time indicators: SDNN, mNN, RMSSD, pNN50 - and spectral parameters: TP, HF and HFnu, LF and LFnu, LF/HF - as well as IVR and IN indices were evaluated. According to the level of SDNN, individuals with conditionally low and conditionally high levels of total HRV were identified - groups LV (40 (31; 47) ms) and HV (64 (58; 70) ms). At rest, HRV parameters in HV-girls were significantly higher than in the LV-subgroup. After BE, a significant increase in SDNN and TP was observed in the LV-subgroup, against the background of a decrease in HF and HFnu and an increase in LF and LFnu, and the LF/HF ratio after BE increased by 80%. In HV-girls after BE, an increase of 6% in heart rate was recorded, but not in total HRV parameters: a decrease in HF and HFnu was compensated by an increase in LFnu, as a result, the LF/HF ratio increased significantly by almost 1.5 times compared to the rest level. In LV-girls, the indicators of autonomic balance index (AVR) and stress-index (SI) were higher by 2.6–2.7 than in the HV-subgroup. After BE, a decrease of 24 and 19% in the parameters of AVR and SI was observed in the LV, but not in the HV-subgroup. Thus, the adaptation of the work of the heart to BE occurred in a similar way in LV- and HV-individuals, however, it differed in different adaptive costs of such an effort for LV- and HV-subjects.

The aim of the study is to investigate the dynamics of venous blood glucose, insulin, and C-peptide in response to intake a meal normalized to body mass in obese patients without and with type 2 diabetes mellitus. Venous blood samples were taken from 7 healthy subjects, 9 obese patients, and 10 obese patients with type 2 diabetes mellitus (mean period of diagnosed diabetes 7 years) before and 30, 60, 90, 120, and 180 min after a mixed meal (6 kcal/kg of body mass); additionally, 9 patients with obesity and type 2 diabetes mellitus and 3 healthy volunteers completed a hyperinsulinemic euglycemic clamp test. In patient groups the energy content of food did not differ, but was 1.8 times higher than in the control. An increase in glucose level one hour after a meal was maximal in patients with type 2 diabetes, but an increase in insulin and C-peptide — in obese patients, that related to impairment of insulin-dependent glucose uptake by tissues and of the rate of insulin secretion (dysfunction of â-cells) in patients. At the same time, an increase in the total area under the curve “C-peptide–time” shows that the maximum secretory response of â-cells is comparable in obese patients without and with type 2 diabetes mellitus. The absolute blood glucose level 90 minutes after a meal was closely correlated with the M-index — the marker of systemic sensitivity to insulin (rs = –0.82, p = 0.002). Our results characterize the features in the regulation of carbohydrate metabolism after intake a mixed meal, normalized to body mass, in people with the varying severity of metabolic disorders, and open up prospects for a wider application of this test in practice.

Одним із завдань контролінгу є інформаційно-аналітична підтримка прийняття управлінських рішень. Метою статті є висвітлення концептуальних засад визначення та реалізації системи контролінгу як інструменту формування конкурентних позицій підприємств харчової промисловості. У процесі дослідження застосовано методи порівняння, аналізу, теоретичного та логічного узагальнення. Методологічною основою став діалектичний метод дослідження. В процесі дослідження доведено, що контролінг є інноваційною концепцією інформаційного та управлінського підходу, яка визначається як система обліково-аналітичних інструментів, що поєднує елементи обліку, контролю, планування і забезпечує оперативне і стратегічне управління досягненням цілей підприємства; виокремлено особливості контролінгу: єдність оперативних і стратегічних рішень у фінансово-економічних обрахунках; новий підхід до фінансово-економічних розрахунків для прийняття обґрунтованих рішень; переосмислення традиційних функцій управління; нове розуміння ролі планово-економічних служб на підприємстві.
Запропоновано схему концепції контролінгу на підприємствах харчової промисловості, принциповим для обґрунтування якої є виділення системи планування і контролю та системи інформаційного забезпечення в межах системи управління.
La distopía energética en la arquitectura urbana contemporánea-
Authors: Hernandez Ayllon Javier Alejo
Published: June 2024

Dystopias present a very particular architecture, with a way of living enclosed in modules and a space subjected to functional segregation, with a fundamentally vertical urban planning and as a clear opposition to the utopian organization of the Garden City. This text introduces into the complex equation of the social relationship between the individual, architecture and nature the problem of energy dependence in the analysis of the passage from the megapolis to the metapolis. This text describes a present built of clean energy production systems with the hypothesis of overcoming the past design in favor of an imagined future that is nourished by the use of wind, in its plausible connection with vernacular architecture in the two scales of a metapolis.

Impervious Surfaces from High Resolution Aerial Imagery: Cities in Fresno County
Authors: Ahn Yushin , Poythress Richard
Published: June 2024

This study investigates impervious surfaces — areas covered by materials with restricted water permeability, such as pavement, sidewalks, and parking lots—due to their crucial role in influencing water dynamics within urban landscapes. The impermeability of these surfaces disrupts natural water absorption processes, resulting in adverse environmental consequences such as increased flooding, erosion, and water pollution. The research employs impervious surface analysis, a method involving the mapping and analysis of these surfaces within specified study areas, including cities, counties, and census tracts. Remote sensing techniques, specifically satellites and aerial imagery, are commonly utilized for the identification and classification of impervious surfaces. In the context of Fresno County, diverse classification methods, encompassing pixel-based, object-based, and deep learning approaches, are employed to classify and evaluate impervious surfaces. Significantly, the deep learning classification method exhibits exceptional performance, achieving an impressive overall accuracy ranging between 85-92%. The study reveals that the estimated percentage of impervious surfaces in Fresno County cities approximates 45%, comparable to the characteristics of medium density residential areas. Noteworthy is the observation in the Fresno/Clovis city area, where the percentage of impervious surfaces escalated from 53% in 2010 (per EnviroAtlas) to 63% in 2020. This 10% increase over a decade closely aligns with concurrent population growth trends in the region. In conclusion, this research underscores the critical significance of comprehending and monitoring impervious surfaces due to their pivotal role in shaping the environmental quality and resilience of urban areas. The insights gleaned from this study provide valuable guidance for the development of effective land use planning and management strategies, specifically tailored to mitigate the adverse impacts of impervious surfaces on the environment and human well-being.

Saving the Earth for Future Generations: Some Reflections
Authors: Bosselmann Klaus
Published: June 2024

Most legal systems recognize trusteeship functions of individuals or institutions to act on behalf and in the interest of those who cannot legally act for themselves. They can be advanced for the effective protection of future generations and the Earth. Guidance for Earth Trusteeship exist in the form of two agreements created by global civil society, the 2000 Earth Charter and the 2018 Hague Principles. Current opportunities include the UN Secretary General’s call for “repurposing the Trusteeship Council”, the UN Summit of the Future and ongoing developments in many countries towards implementing ecological integrity and rights of nature into their legal systems.
Plasma pTau181 Predicts Clinical Progression in a Phase 2 Randomized Controlled Trial of the 11β-HSD1 Inhibitor Xanamem® for Mild Alzheimer’s Disease
Authors: Taylor Jack , Jaros Mark , Chen Christopher , Harrison John , Hilt Dana
Published: June 2024

Background: Blood biomarkers are proposed as a diagnostic alternative to amyloid PET or cerebrospinal fluid (CSF) analyses for the diagnosis of Alzheimer’s disease (AD). Relatively little is known of the natural history of patients identified by different blood biomarkers. Objective: To identify patients with elevated plasma phosphorylated tau (pTau)181 from a prior Phase 2a trial, and explore the natural histories of their clinical progression, and potential efficacy of Xanamem, a selective inhibitor of 11beta-hydroxysteroid dehydrogenase type 1 (11β-HSD1) in these patients. Methods: A prespecified, double-blind analysis was conducted in 72 participants with clinically diagnosed AD and available plasma samples from baseline and Week 12 of the “XanADu” Phase 2a trial of Xanamem versus placebo. The analysis prespecified plasma pTau181 > median to identify patients more likely to have AD (“H”, > 6.74 pg/mL, n = 34). Cohen’s d (d) of≥0.2 defined potential clinical significance. Results: In the placebo group, H patients showed greater clinical progression compared to L patients (pTau181≤median) on ADCOMS (d = 0.55, p < 0.001), CDR-SB (d = 0.63, p < 0.001), MMSE (d = 0.52, p = 0.12), and ADAS-Cog14 (d = 0.53, p = 0.19). In H patients, a potentially clinically meaningful Xanamem treatment effect compared to placebo was seen in the CDR-SB (LS mean difference 0.6 units, d = 0.41, p = 0.09) and Neuropsychological Test Battery (NTB; LS mean difference 1.8 units, d = 0.26, p = 0.48) but not ADCOMS or ADAS-Cog14. Conclusions: This trial demonstrates that elevated plasma pTau181 identifies participants more likely to have progressive AD and is a suitable method for enrichment in AD clinical trials. Xanamem treatment showed evidence of potential clinically meaningful benefits.
