Authors: Антонова И.С. , Барт В.А. , Телевинова М.С. 
Published: December 2024

Исследованы кроны деревьев виргинильного и генеративного онтогенетических состояний семи видов лиственных растений: Ulmus glabra, Ulmus minor, Celtis sinensis, Zelkova carpinifolia, Aesculus hippocastanum, Fraxinus excelsior, всего более 500 особей. Крона дерева состоит из двух принципиальных морфофункциональных частей: «скелета» и «кружева» кроны. Их функции, появление, развитие и время существования в кроне связаны с геометрическим пространством ветвей. Существование этих побеговых комплексов в кроне основано на разных пространственно-временных принципах. В результате многолетних наблюдений выделены типы первичного и вторичного «кружева» кроны, в составе первичного «кружева» выделены две подгруппы. Исследованы особенности развития ветвей деревьев в онтогенезе. На уровне дерева в целом предлагается рассматривать весь комплекс «кружева» кроны, как пример математической модели «стоячая волна» (солитон).
The crowns of trees of virginal and generative ontogenetic state of seven species of deciduous plants were studied: Ulmus glabra, Ulmus minor, Celtis sinensis, Zelkova carpinifolia, Aesculus hippocastanum, Fraxinus excelsior, in total more than 500 individuals. A crown of a tree consists of two principal morphofunctional parts: the “skeleton” and the “lace” of the crown. Their functions, appearance, development and time of existence in the crown are related to the geometric space of branches. The presence of these shoot complexes in the crown is based on different spatial and temporal principles. As a result of long-term observations, the types of primary and secondary “lace” of the crown have been identified, including two subgroups of the primary “lace”. The peculiarities of the development of tree branches in ontogenesis have been investigated. At the level of a tree as a whole, it is proposed to consider the entire complex of the crown “lace” as an example of the mathematical model “standing wave” (soliton).

Published: December 2024

Представлены результаты изучения сезонного ритма развития в условиях культуры двух редких видов рода Iris L.: Iris pumila L. и I. scariosa Willd. ex Link. Установлено, что в условиях Башкирского Предуралья исследуемые виды достигают генеративной фазы развития и плодоносят. Фенологические фазы у I. scariosa зависят от условий года вегетации, но в меньшей степени, чем у I. pumila, поскольку его цветение происходит в более поздние сроки. Цветение одного цветка I. pumila продолжается от 4 до 6 дней, всей группы наблюдаемых растений – в среднем 12 дней. Длительность цветения одного цветка I. scariosa составляет от 3 до 5 дней. Средний период цветения группы растений – 7 дней. Также исследована изменчивость окраски околоцветников в природных ценопопуляциях обоих видов на Южном Урале (Республика Башкортостан и Оренбургская область). У I. pumila в десяти ценопопуляциях выявлено 30 форм окраски, из которых в наиболее крупных ценопопуляциях одновременно встречается 10–12; в северных районах преобладают фиолетовоцветковые растения, южнее произрастает больше желтоцветковых. У I. scariosa отмечено 11 форм с близким (6–7) числом колеров околоцветника в двух исследованных ценопопуляциях, преобладает фиолетовая форма окраски.
The article presents the study results of the seasonal development in culture of the two rare species of the genus Iris L., i.e. Iris pumila L. and I. scariosa Willd. ex Link. In the Bashkir Cis-Urals, the studied species reached the generative phase of development and bore fruit. Because of the later onset of the flowering period, the phenological phases of I. scariosa depended on the growing season conditions to a lesser extent than those of I. pumila. Blooming of one I. pumila and one I. scariosa Willd. ex Link flower lasted –6 days and 3–5 days, respectively, whereas the flowering of the entire study group of I. pumila and I. scariosa plants – 12 and 7 days on average. Colour variability of perianth in natural cenopopulations of both species in the Southern Urals (the Republic of Bashkortostan and Orenburg Oblast) was investigated as well. We identified 30 colour forms in ten cenopopulations of I. pumila, 10–12 of which were concurrently recorded in the largest ones. Violet-flowered plants dominated in the northern regions, while yellow-flowered in the south. In the two studied coenotic populations, I. scariosa had 11 forms with a similar (6–7) number of perianth colors, where violet prevailed.

Published: December 2024

Summary
The main lever of precision agriculture is technology that provides a better understanding of the agro-ecological conditions, enables decision-making based on facts and natural laws, and facilitates precise implementation of practices based on local specificities. One of the key elements of plant production is nitrogen (N), which is traditionally applied as mineral fertilizer in large quantities. Optimizing nitrogen input is one of the priorities in precision agriculture, not only for its importance in the plant food chain but also for its environmental impact. This study investigated the potential of two optical sensors, GreenSeeker and Plant-O-Meter, in predicting nitrogen supply during the 2021-2022 growing season. The experimental material in this study included two wheat varieties, subjected to different nitrogen application rates. The objective was to estimate the potential of using NDVI (Normalized Difference Vegetation Index) measurements of wheat canopy, which are indicators of plant status, and to analyze correlations between these values and final wheat yield. GreenSeeker and Plant-O-Meter sensors, which emit light at precise wavelengths and measure plant reflectance, were used for monitoring plant status and NDVI measurements. The results showed a strong correlation between the NDVI values measured by both sensors. However, this relationship decreased during the fully ripe stage due to physiological changes in the wheat plants. The correlation between NDVI values and grain yield differed significantly between the evaluated sensors. Additional correlation analyses between NDVI measurements and yield indicated differences associated with wheat varieties, indicating that the varieties responded differently to environmental conditions. This study aligns with current agricultural approaches and contributes to more efficient and environmentally friendly agricultural practices.

Published: December 2024

Summary
The primary objective of this study was to forecast the labour productivity in Algeria's agricultural sector by the year 2030 using the seasonal autoregressive integrated moving average (SARIMA) model. Quarterly data spanning from the first quarter of 1991 to the fourth quarter of 2021 were analyzed, identifying the SARIMA model (1, 1, 1) x (1, 1, 1, 4) as the most suitable for capturing seasonal variations and accurately fitting the historical data. The methodology utilized Python 3.11.5 for data processing and modelling, thus enabling a comprehensive analysis of the trends and patterns in Algerian agricultural labour productivity. The results obtained demonstrate robust and steady growth in the Algerian agricultural labour productivity attributable to advancements in farming techniques, technological innovations, and evolving market conditions. These findings highlight the critical role of accurate forecasting in effective policy-making and resource allocation. By providing insights into future productivity trends, the research supports the development of strategies aimed at enhancing the resilience and sustainability of the agricultural sector, particularly in the face of challenges posed by climate change and geopolitical tensions. The conclusion underscores the importance of leveraging predictive models such as SARIMA in informing agricultural policies and ensuring the long-term food security and economic stability in Algeria.

Authors: Niman Susanti , Mustikasari  , Daulima Novy Helena Catharina , Gayatri Dewi 
Published: December 2024

Abstract

Objective
The aim is to develop and verify the feasibility of an adolescent coping model in seasonal flood-prone areas. This coping model supports mental health nurses’ practical application to adolescents in flood-prone areas.

Methods
We developed the adolescent coping model based on the processes established in three integrated theories: self-care management for vulnerable populations, coping approaches, and coping with disaster. We conducted semi-structured interviews with 15 participants to explore their perspectives and experiences with flood disasters. We used purposeful sampling for maximum diversity. Data were collected through face-to-face, in-depth interviews. Data were transcribed verbatim, followed by qualitative content analysis. The coping model of adolescents in flood-prone areas was analyzed qualitatively and inductively from the viewpoint of acceptability.

Results
The following five categories were identified: (1) coping process post-disaster; (2) coping approach; (3) community power; (4) vulnerability; and (5) self-potential. These domains formed a model for coping model adolescents in seasonal flood-prone areas. Accordingly, our findings showed that the model could be practical for mental health community nursing.

Conclusions
Mental health nurses can use the coping model for disaster mental health nursing in adolescents in flood-prone areas. The application of this model will help adolescents increase self-efficacy.

Authors: Nakhal Mohamad Al , Fawaz Mirna , Khabaz Karim , Rayan Ahmad , Hani Salam Bani , ALBashtawy Mohammed 
Published: December 2024

Abstract

Objective
To explore the clinical rationale of critical care nurses for personalizing monitor alarms. One of the most crucial jobs assigned to critical care nurses is monitoring patients’ physiological indicators and carrying out the necessary associated interventions. Successful use of equipment in the nursing practice environment will be improved by a thorough understanding of the nurse’s approach to alarm configuration.

Methods
A mixed-method design integrating quantitative and qualitative components was used. The sample of this study recruited a convenience sample of 60 nurses who have worked in critical care areas. This study took place at Lebanese American University Medical Center Rizk Hospital, utilizing a semi-structured interview with participants.

Results
The study demonstrated the high incidence of nuisance alarms and the desensitization of critical care nurses to vital ones. According to the nurses, frequent false alarms and a shortage of staff are the 2 main causes of alarm desensitization. Age was significantly associated with the perception of Smart alarms, according to the data (P = 0.03). Four interconnected themes and subcategories that reflect the clinical reasoning process for alarm customization were developed as a result of the study’s qualitative component: (1) unit alarm environment; (2) nursing style; (3) motivation to customize; and (4) clinical and technological customization.

Conclusions
According to this study, nurses believe that alarms are valuable. However, a qualitative analysis of the experiences revealed that customization has been severely limited since the healthcare team depends on nurses to complete these tasks independently. Additionally, a staffing shortage and lack of technical training at the start of placement have also hindered customization.
Multilevel Investigation of Leadership Prototype Perception: Political Behavior in Relation to Effectiveness and Trust
Authors: Arslan Aykut , Yener Serdar , Korkmaz Fatma , Erogul Murat Sakir 
Published: December 2024

Abstract

Background/Purpose
Empirical evidence suggests that a leader’s political skills may act as a moderator that might decrease the effect of prototypicality’s impact on trust and on leadership effectiveness. The study investigated leading political skills as second-level regulatory variables in connection to leader effectiveness and trust with the purpose of testing a cross-level moderated mediation model within a traditionally collectivist culture like Turkey in efforts to contextualize and expand understanding of leadership prototype perception.

Methods
A total of 442 service sector employees and 28 executive managers were interviewed. Two surveys in two separate time periods were conducted. Multilevel path analysis was used to evaluate the hypotheses.

Results
The findings suggest that there is a strong and significant impact of leader prototypicality on leadership effectiveness and a direct impact on trust. Results indicate that leaders who are trusted by their subordinates are perceived as more effective in their leadership roles. Lower levels of trust from subordinates are negatively associated with leader effectiveness.

Conclusion
If leaders cannot provide their followers a contextualized sense of empowerment and development, they are perceived to not provide high levels of emotional trust. Therefore, there is greater need for multilevel contextualized studies taking account of collective, two-sided, embedded experiences within groups.
Sustainability Indicators of Four Biomass Pretreatment Methods for the Energy Transition in Colombia
Authors: Orozco Yohanna Cabrera , Alarcón Jennifer Alejandra Patricia Gutiérrez , Orozco Andres Cabrera 
Published: December 2024

Objective: To compare pretreatment methods for lignocellulosic biomass, focusing on the feasibility of using renewable energy through electric-powered techniques.

Theoretical Framework: The energy transition is expected to generate surplus green electricity. This surplus can enable sustainable small-scale lignocellulose pretreatments.

Methods: We compared two conventional pretreatments, steam explosion (SE) and ammonia fiber expansion (AFEX), with two electric-powered pretreatments, reactive extrusion (RE) and ball milling mechanocatalysis (Me). Feasibility was assessed using these indicators: normalized total value added (TVA), safety, health, and environmental (SHE) impacts, and energy efficiency (carbohydrate yield to energy consumption ratio), based on literature data. A cumulative index (CI) combined TVA with SHE impacts, emphasizing that high economic value alone is insufficient if the pretreatment negatively affects safety, health, or the environment.

Results and Discussion: Economic viability varied; SE and AFEX performed best (TVA range: SE: 0.04 to 0.54; AFEX: 0.08 to 0.21). RE exhibited potential despite energy efficiency challenges, unlike Me (TVA: RE: -2 to 0.01; Me: -28 to -8). When considering CIs that combine TVA with SHE impacts, RE was competitive with AFEX (CI: RE: 1.3-2.9; AFEX: 1.7-1.9; SE: 0.7-1.2; Me: 8.9-28.9). Energy efficiency showed gains for all methods (Me: 0.02-0.18; RE: 0.38-3.94; SE: 1.22-3.59; AFEX: 1.33-3.92 kWh/kg). RE overlaps with SE and AFEX indicating potential.

Research Implications: The data suggest feasible scenarios for integrating renewable energy into biomass pretreatments, enabling small-scale energy utilization.

Originality/Value: The analysis explores diverse energy uses to enhance sustainability, by presenting practical possibilities for community involvement for a fair and equitable energy transition.

Authors: Vera-Marmanillo Verónika , Churata Rossibel , Ortiz-Valdivia Yosheff , Gordillo-Alarcón Carlos , Tupayachy-Quispe Danny , Almirón Jonathan 
Published: December 2024

Objective: Carry out the mineralizing and detoxifying treatment of cigarette butts, as a solution to the contamination of hazardous non-recyclable waste due to the amount of toxic substances they contain.

Theoretical Framework: The research used the applied biotechnology of saprobiotic macromycetes as regenerative treatment systems for the mineralization of toxic substances, through the detoxification of cellulose and lignin fibers due to the enzymatic activity of cellulases. The proliferation of Pleurotus ostreatus and Pleurotus dejamor occurred under induced conditions of HR, ºT and light hours.

Method: The methodology includes the degradation process of cellulose and lignin fibers verified by SEM after 45 and 75 days of evaluation. In addition, the EDS allowed studying the mineralization of the indicator elements. The weekly evaluation periods (every 3 days) for 4 months, under conditions of RH, ºT and induced light hours, showed mycelial growth on the substrate of lignocellulosic waste from cigarette butts.

Results and Discussion: The results demonstrated the greatest mineralization of Cl and S at 45 days and Ti, Si, Al at 75 days. Controlled environmental parameters are essential for the development of basidiomycetes and the available carbon source represents the growth factor.

Originality/Value: The demineralized, detoxified and partially degraded substrate will serve as raw material for reintegration into the production chain, promoting the circular economy, valorizing waste and reducing the environmental impact to zero.

THE PERCEPTION OF BAÍA FORMOSA/RN RESIDENTS OF ELECTRONIC WASTE

ABSTRACT
In most recent years, the replacement of electronic devices has become more frequent, resulting in the generation of waste, which can then be inadequately disposed of. The aim of this research was therefore to gain an insight into the perceptions of the residents in the city of Baía Formosa - RN regarding this issue. We conducted this exploratory study, where a questionnaire was administered in person between September (2022) and April (2023), interviewing 62 residents individually in public places in the city. Most respondents were men (54.84%), living in urban areas (91.94%), with up to high school education (90.33%). The data showed that the interviewees lacked knowledge on the subject (51.61%), since most of them reported a lack of collection points for electronic waste (88.71%) and a high number of interviewees (46.78%) discarded electronic waste in the common garbage. Therefore, it is important to engage in local mobilization with public policies and lectures to raise awareness among the population and implement electronic waste management plans, making it possible to reduce the risks to human and environmental health.

Keywords: Residents, electronic waste, disposal.
