Published: May 2023

Panicum coloratum es una especie gramínea C4 nativa de Sudáfrica. En Argentina, se la valoriza por su producción forrajera de buena calidad en ambientes en los que los recursos son limitados. La cosecha de semillas esta dificultada por la madurez no uniforme de sus cariopsis dentro de la panoja y su rápida desarticulación. El objetivo de este trabajo fue evaluar el potencial de dos cultivares de Panicum coloratum para desarticulación de cariopses, germinación y caracteres relacionados a panoja con efectos sobre la producción de semillas en dos ciclos de cultivo (2017 y 2019). La desarticulación de cariopses fue evaluada semanalmente usando trampas para semillas. Los resultados mostraron diferencias significativas entre cultivares en ambos años. El pico de caída ocurrió en el mismo momento fenológico en ambos cultivares. Respecto a la germinación, el comportamiento de ambos cultivares fue similar en ambos años y entre diferentes tratamientos aplicados. Para los caracteres relacionados a panoja, se encontró amplia variabilidad y correlaciones altas y positivas entre las variables evaluadas mediante un Análisis de Componentes Principales, tanto para ambos años como para el conjunto de datos. En todos los casos, las dos primeras Componentes Principales explicaron un alto porcentaje de la variabilidad total. La información generada en este trabajo permite concluir que cv. Kapivera presentó mayor retención y menor producción de semillas que cv. Bambatsi.

Published: May 2023

La producción agrícola depende en gran parte del uso de fertilizantes, estos generalmente se aplican en forma sólida por proyección y su transporte puede afectar la calidad física y de su aplicación, afectando la eficiencia de uso y el rendimiento de los cultivos. El objetivo fue evaluar el efecto de dos formas de transportar fertilizante, (tornillo sinfín y cinta transportadora), sobre la calidad física del fertilizante y de su aplicación en el terreno. Se hipotetizó que el sistema de transporte mediante tornillo sinfín afecta la calidad física de la urea y, en consecuencia, su calidad de aplicación en el terreno, respecto a la cinta transportadora. El trabajo se realizó en septiembre del año 2020, se utilizó fertilizante urea y dos sistemas de transporte, tornillo sinfín tradicional y cinta transportadora. Se tomaron muestras de fertilizante antes y después de pasar por los sistemas de transporte y se evaluó la densidad aparente, granulometría y dureza. El fertilizante transportado fue aplicado con una fertilizadora de doble discos y se le evaluó la uniformidad de distribución de las dosis en el terreno. El sistema de transporte por tornillo sinfín provocó una disminución en la densidad aparente y dureza del fertilizante, generando más cantidad de partículas finas (<2mm). Esto afectó su distribución en el terreno generando, para una misma configuración de la fertilizadora y ancho de labor, menor calidad de aplicación, es decir coeficientes de variación de la dosis distribuida mayor que cuando se utilizó la cinta transportadora. No se rechazaron las hipótesis planteadas.

Strategic Methods for Integrating Building Science and Design
Authors:   Howard University, Nduom Dahlia , Maloo Nea ,   Howard University
Published: May 2023

The design studio has often been considered central to architecture education, while the building science courses are the backbone of architecture. While NAAB accredited programs require a body of structures and buildings science courses, the integration of these courses into design studios has been implemented to varying degrees across NAAB accredited institutions. Some programs tackle this integration through a comprehensive design studio in the upper-class years, while others advocate for this integration at the 1st-year design studio. The debate surrounding integration between building science courses and design studio continues with some questioning how much integration is necessary in the early design studio, while others seeing it as essential to the design studio and pushing for a direct link. This paper aims to add to the conversation by relaying our experiences in proposing a pedagogical symbiotic relationship between the building science courses and the 3rd-year design studios at our university. This paper questions how can we envision building science and studio courses as a Yin and Yang relationship where one can’t exist without the other? How can the integration lead to more successful understanding of concepts taught in building science courses? How can the work being done in design studio be used as a teaching tool in the building science courses and vice versa? What are the best practices for achieving this integration? Integration as a teaching tool was tested during the students’ 3rd-year. Subject matter from Environmental Systems and Structures courses were used in the development of discrete exercises to convey specific concepts instead of challenging the students with a complete integration as would occur in a later comprehensive design studio or thesis. The paper presents lessons learned, surveys conducted before and after the exercises and conclusions from the authors on how to improve on this pedagogical approach.

HIDDEN FINE ART WITH IR COLORANTS
Authors: Ziljak Grsic Jana , Tepes Golubic Lidija , Stanacev Bajzek Sanda
Published: May 2023

We are surrounded by video surveillance cameras that register separately in two light areas: visible to our naked eye - Red, Green Blue record and near infrared record (NIR � Z). In this article, we present quantitative data on the measurement of light absorption for fine art colorants. We expand the theory and practice of Infrared Art by giving examples of artists who paint so-called "infrared pictures" as a new, different creation of a work of art, a new expressive possibility that the artist adapts to his artistic nature, that is, to his expression, and by no means as a new technological possibility to which he will subordinate himself and his art. Infrared Art is a completely new method of creating works of art with regard to the infrared area, that is, it is a discovery and a technology that allows us to create and reproduce works of art with full control over the management of dual images and messages that can be communicated through images, via information that is visible and invisible to the eye. The increasing interest in the question of colors and colorants and their physical properties encourages us not to keep Infrared Art, that is, infrared technology, in the sphere of experiments, but to make maximum use of its applicability in all aspects of visual communication and information communication.

Community empowerment aims to empower individuals within a community to realize their full potential and skills. The community referred to is one where there is no one who is unproductive or unemployed. Unemployment is a state where members of the labor force do not have a job and are not actively seeking one at the moment. Unemployment can be addressed, one of which is through community empowerment by developing food processing, particularly those made from fish. If good operational and marketing practices are not followed by good fish processing development efforts, then there will be no high economic benefits or value. Qualitative research methods were applied in this study. The results of this study are: 1) The researcher concluded that the community empowerment process through the development of smoked sagarurung fish products in the Talang Ubi District of PALI Regency consists of several stages, namely community involvement, program planning, program implementation, and continuous evaluation. 2) Supporting factors for community empowerment are the facilities provided by the government and related agencies, while inhibiting factors include changes in mindset, the dominance of raw materials sourced from outside the region, and a lack of understanding of digital marketing. 3) The results of community empowerment are an increase in the life skills of smoked sagarurung fish business owners, fulfillment of their economic needs, and an increase in their understanding of high-quality smoked sagarurung fish processing.

Published: May 2023

Perioperative use of opioids has many detrimental effects on health care outcomes and is currently accelerating the worldwide epidemic of opioid addiction prescription and overdose death. Due to the excessive use of opioids and their side effects, a new strategy was developed in order to achieve a balanced general anesthesia, namely opioid-free anesthesia (OFA). This technic can be used in most surgeries using alternative analgesic drugs. We reported a female patient, 59 years old, referred to the Department of Anesthesia from the Department of Surgery for elective thyroidectomy. The patient was diagnosed as ASA 3, Actual: difficult airway, subclinical hyperthyroidism, drug allergy, controlled hypertension (with amlodipine 10 mg); Potential: difficult intubation. We used general anasethesia with endotracheal tube, premedication with midazolam 2 mg iv, analgesic with dexme-detomidine 0.1 mcg /kg BW worn out in 10 minutes. The operation went smoothly and on the 2nd day after surgery, the patient was transferred to the regular ward. In conclusion, the use of non-opioid anesthetic drugs is an effective and rational choice in order to reduce the side effects of postoperative opioids in this patient.

Published: May 2023

Aim. The presented study aims to identify current trends in the global corporate bond market with environmental, social, and management objectives of the issuance ofESGbond and to assess the prospects for their development.

Tasks. The author analyzes the segments of the globalESGbond market; determines the causes of the emerging trends and their impact on the state of globalESGfinancing.

Methods. This study uses general scientific methods of cognition, in particular induction and deduction, synthesis, comparative and retrospective analysis. The fundamental regulatory documents ofESGbond taxonomy are investigated, and statistics from representative sources are analyzed. The latter includeInternational Capital Market Association,SPGlobal,Barclays,Goldman Sachs,Refinitiv, andClimate Bond Initiative.

Results.Based on the conducted research, the reasons for the active growth in 2021 and the slowdown in the development of the globalESGbond market in 2022 are established, and its short-term prospects are assessed. The prospects are systematized according toESGbond varieties. Analysis of the mutual influence of global trends on the state of the globalESGbond market indicates the prevalence of external factors.

Conclusions.According to the results of the analysis, theESGbond toolkit seems to be investment-relevant. In 2022, major discussions regarding globalESGdebt revolved around market quality and potential greenwashing. Intensive measures are taken in these areas at the macro and micro levels. The volume ofESGbond issuance in 2023 should be restored as interest rates in developed countries stabilize and global inflation rates decrease. Experts remain positive in their expectations and forecasts for 2023, but the quality of green bond and bond related to sustainable development is alarming.
Comparative assessment of competitiveness and external costs of electric car and car with internal combustion engine (on the example of Moscow)
Authors: Baraboshkina A. V.
Published: May 2023

Aim. To carry out a comparative evaluation of the competitiveness of electric car and car with internal combustion engine (ICE) of the middle price segment and their external costs on the example of Moscow.

Tasks. To describe the methodology and estimate the total cost of ownership of an electric car “Moskvich 3e” and its gasoline counterpart “Moskvich 3”; calculate the external costs of an electric car and a gasoline-powered car related to greenhouse gas emissions and air pollutants; estimate the total cost for society.

Methods. In order to compare the competitiveness of cars with different types of engines, the method of total cost of ownership was used; in the aspect of obtaining the total cost for society by economic evaluation of emissions, the external costs associated with climate change and air pollution were calculated.

Results. Currently, the total cost of five-year ownership of electric car “Moskvich 3e” is higher in comparison with the car “Moskvich 3” practically by 461 thousand rubles, even taking into account the existing support measures in Moscow. The difference in external costs due to greenhouse gas emissions and air pollutants is about 68.3 thousand rubles. The electric car is more environmentally friendly and contributes less to climate change. The difference in the total cost of five-year ownership of an electric car “Moskvich 3e” and its gasoline analogue, taking into account the external costs (total cost for society) is 392 thousand rubles. This means that the internalization of external costs may slightly increase the competitiveness of the electric car.

Conclusions. The study will allow potential buyers to assess the real affordability of vehicles of interest to them, in particular vehicles “Moskvich 3” and “Moskvich 3e”. The obtained results may serve as a basis for further development of support measures for electric motor vehicles in Moscow, for example, when calculating the amount of subsidy necessary to ensure the competitiveness of electric cars of the medium price segment.

E-learning Portal Success in higher education organizations: A multi-group comparison
Authors:   General Education Department, City University, Dhaka, Bangladesh, Roy Sanjoy Kumar
Published: May 2023

Purpose: This study provides an analytical framework based on the literature to evaluate the effectiveness of E-learning portals. The study aims to contrast the accessibility of e-learning portals from the perspectives of business and engineering students. Research methodology: Using convenience and snowball sampling methods with the help of Google polls, the data was acquired from 482 students, including engineering and business students. The study used a seven-point Likert-type questionnaire to gather data. The study employed PLS-SEM to do a multi-group analysis and examine group differences. Results: The results revealed user satisfaction predicts the system used for both models. Only e-service quality is the significant predictor of user satisfaction and the system used in the business model, but the system and information qualities are also predictors in the engineering model. Finally, the success of an e-learning portal is positively correlated with user satisfaction and system use. Limitations: This study consists of only a sample of 482 students. Future research may take into account using a bigger sample size. Additionally, this study mostly focused on how students perceived the efficacy of the e-learning portal while ignoring the viewpoints of the instructors and the institution, which may vary. Contribution: Higher administration in Bangladeshi educational institutions will find the study helpful in building policies and plans for the growth of e-learning portals. Novelty: This work validates the DeLone and McLean Model in the context of Bangladeshi undergraduate students. The study shows how business and engineering students' access to e-learning portals varies.

Multi-timescale Power System Operations for Electrolytic Hydrogen Generation in Integrated Nuclear-Renewable Energy Systems
Authors: Rahman Jubeyer , Jacob Roshni , Zhang Jie
Published: May 2023

This study explores how sector coupling via In- tegrated energy systems (IES) can improve the operational flexibility of the power grid, while hydrogen is gaining traction as a versatile energy carrier. Specifically, we have evaluated the operational benefits of integrating two electrolytic processes for hydrogen generation, namely low-temperature electrolysis (LTE) and high-temperature steam electrolysis (HTSE), into a nuclear- renewable IES using a 3-cycle power system operation frame- work. Detailed steady-state models of the electrolytic hydrogen generating facilities are constructed, with the HTSE process represented using standard transient models to account for the steam-bypass scheme from the nuclear reactor. These models are then integrated into a renewable-intensive power network model (specifically, the NREL 118-bus system). To simulate the operation of the integrated system across multiple timescales, a multi-timescale scheduling and dispatch tool is employed. Results indicate that while both electrolytic processes contribute to signif- icant flexibility enhancement and renewable energy curtailment reduction, the LTE process offers more operational benefits than the HTSE process across multiple timescales.

Published: May 2023

Traditionally, strawberries are harvested manually when the typical colour of the cultivar does not reach at least 80% of the surface. The focus of this research activity is to develop an automatic system based on image analysis in order to objectively define the optimal harvest time. Strawberries (cv. Sabrosa), with different degrees of maturation, were analyzed in four different harvesting periods and subsequently selected and classified, based on the ripening percentage, in three maturity classes: R0-25, R50-70 and R75-100. Each class of 10 strawberries, evaluated in triplicate, was subjected to image analysis and physiological and qualitative evaluation by measuring the following parameters: respiration rate, pH, total soluble solids content, and titratable acidity. The images captured, by a digital camera, were processed using Matlab® software and all the data found were supported by multivariate analysis. The image processing has made it possible to create an algorithm measuring objectively the percentage and the saturation level of red assigning the fruits to each class. Principal component analysis shows that discriminating parameters are the Chroma and the red Area, then used in a Partial Last Square Regression (PLSR) model to predict the TSS/TA ratio with R2 of 0.7 and 0.6 for calibration and validation set, respectively.

Edible flowers are appreciated due to their aesthetic features, nutritional value and antioxidant properties. Tulbaghia simmleri Beauv. (Amaryllidaceae family) flowers are characterized by a pleasant garlic taste and are consumed both as fresh and dried products. The aim of this work was to assess the effect of chilling temperature (+4°C) on the visual quality, nutritional content, and aroma profile of T. simmleri flowers after two (T2) and six (T6) days of storage. Colorimetric analysis highlighted a reduction in petal brightness at T6 and hence their darkening, due to a significant increase in a* coordinate and decrease in the b* one. Total polyphenols and flavonoids content remained unchanged until the end of the experiment, while total anthocyanins increased at T2. Flowers antioxidant activity (DPPH assay) decreased progressively during cold storage, while catalase (CAT) and ascorbate peroxidase (APX) activities increased. The aroma profile was analyzed by HS-SPME associated with GC-MS, underlining that fresh flowers were dominated by high content in monoterpenes (around 80%), with 1,8-cineol as main compound (53.1%). Cold storage reduced this class of volatiles while sesquiterpenes and non-terpenes increased; between them, benzyl benzoate reached 12%.

Nanosponges can favour the gradual release of molecules over a prolonged time, increasing the bioavailability and action of preservatives and phytoregulators, reducing the concentrations usually adopted. In floriculture, they have previously been proposed for the delivery of anti-ethylene compounds to improve the shelf-life of cut flowers. However, the potential of nanosponges is not only limited to these compounds. The present study evaluated the effects of β-cyclodextrin-based nanosponges and growth regulators on the post-harvest longevity of cut flowers of ornamental species. One novelty was the use of Forchlorfenuron (CPPU), a growth regulator belonging to the group of cytokinins predominantly used in fruit cultivation, to evaluate its potential to increase the shelf-life of cut carnations (Dhiantus caryophyllus). Specifically, as far as post-harvest longevity is concerned, the treatments involved the use of: deionised water; nanosponges and deionised water; nanosponges loaded with CPPU; nanosponges loaded with a classic solution for cut flowers, composed of sucrose, aluminium sulphate and 8-hydroxyquinoline sulphate. Preliminary results show that the nanosponge and deionised water complex and the nanosponge and classical solution complex prolonged the longevity of the cut flower by up to 20 days, compared to the control (17 days). In contrast, the CPPU-nanosponge complex showed similar results to the control. Replication of the research is necessary to validate the results.

Superficial scald (SS) is one of the main physiological disorders affecting postharvest of pears. Its onset is linked to oxidative processes. Antioxidant compounds such as ascorbic acid and phenolics could play a key role in preventing SS. Growing environment and fruit quality also have an influence on SS symptoms occurrence. The aim of this project is to understand the relationship between antioxidant activity, phenolic content, and development of SS in ‘Abate Fétel’ pear. Moreover, the effect on SS of fruit maturity at harvest was assessed using multivariate statistical approach. Data were collected in thirty orchards in the Emilia-Romagna region (Italy) in three seasons (2018, 2019 and 2020), and the fruit were stored in a regular atmosphere for 120 days. Antioxidant capacity was determined by 2,2-diphenyl-1-picrylhydrazy (DPPH) method and total phenol content by Folin-Ciocalteau colorimetric protocol. The results showed that 340 mg of ascorbate/100 g of FW and 300 mg of gallic ac./100 g of FW at least provide good protection against SS. Multivariate analysis indicated that pulp firmness  and index of absorbance difference ( lAD ) seem to keep low the SS occurence, when at harvest are higher than 6.3 kg and 1.9, respesctively. In conclusion, it would be possible to build a forecasting model to control SS that considers pre-harvest data and content of antioxidants in different orchards, to improve the postharvest management of ‘Abate Fétel’.

Display boards have played a significant part in mass communication over the years. This work intends to propose an Internet of Things (IoT)-based online notice board. The proposed solution includes an online information flash board using IoT to decrease paperwork, time, and labour. Things are linked to the internet by IoT. As a result, the internet can be used to access the information flash board from anywhere in the world. The board has an interface for a Wi-Fi module to provide internet connectivity. The message is received from the specified user and shown on the flash board using the Wi-Fi module that is installed at the digital notice board. According to this suggested model, an authorised admin can post a message from any location, and the message will appear on the LED. The suggested concept includes several applications, such as support desks in transportation hubs including train, bus, and airport terminals that provide travellers with current/updated information. It works better, especially in congested areas like supermarkets, and decreases costs. Any remote region of the world can be represented on the screen with the most recent news, which is made possible only by IoT.
