Artificial neural networks for monthly precipitation prediction in north-west Algeria: a case study in the Oranie-Chott-Chergui basin
Authors: Bouach Ahcene 
Published: January 2024

Abstract
The north-west region of Algeria, pivotal for the nation's water resources and agriculture, faces challenges from changing precipitation patterns due to climate change. In response, our study introduces a robust forecasting tool utilizing artificial neural networks (ANNs) to predict monthly precipitation over a 12-month horizon. We meticulously evaluated two normalization methods, ANN-SS and ANN-MM, and assessed four distinct approaches for selecting input variables (no selection, ANN-WO, ANN-CO, and ANN-VE) to optimize model performance. Our research contributes significantly to the field by addressing a critical gap in understanding the impact of evolving precipitation patterns on water resources. Among the innovations, this study uniquely focuses on medium-term precipitation forecasting, an aspect often marginalized in previous research. Noteworthy outcomes include correlation coefficients of 0.48 and 0.49 during the validation phase, particularly with the Endogen variables and correlation-optimized models using Min-Max normalization. Additionally, the Min-Max normalized technique achieves an impressive 67.71% accuracy in predicting the hydrological situation based on the Standard Precipitation Index.

Abstract

The reliability of evapotranspiration (ET) models is crucial to comprehending land–atmosphere interactions and water balance dynamics in various available resources of the model. This study compared two different models based on energy and water balance models, a surface energy balance system (SEBS) and spatial processes in hydrology (SPHY), evaluated against ground observation data from flux towers for different land-cover characteristics (forest and savanna) in southeast Africa. We found that both models have good correlation with flux-tower data for both sites (ZM-Mon and ZM-Kru). The SEBS model showed a lower root-mean-square error (RMSE; 2.17 mm day−1) at the savanna site (ZM-Kru) than the SPHY model (2.27 mm day−1). However, at the forest site (ZM-Mon), the SEBS model showed a higher RMSE value (1.90 mm day−1) than the SPHY model (0.88 mm day−1). Then, we analyzed the ET model's sensitivity to the precipitation variable. We found that SPHY overestimated ET during the winter season and underestimated it during the summer season, which might be influenced by the dependency of the SPHY model on water excess and water shortage stress parameters in ET calculations. Overall, SPHY, with fewer input data, showed a reasonably good result compared with SEBS. The results revealed that each model possesses its unique strengths and limitations in relation to specific land covers and vegetation composition, offering opportunities for improvement and optimization.

This study was conducted in Musanze district, Rwanda, to evaluate the net benefits of silky oak (Grevillea robusta) production for small farmers. A semi-structured questionnaire was administered to 100 households distributed in four villages. The cost-benefit ratio was used as a decision-making tool. A diameter tape and a Haga altimeter were used to measure the DBH and height of grevillea and other dominant agroforestry tree species. Results indicate that 66 % of laborers were family members, gaining 625 Rwf per person day with grevillea production (US$ 0.61, with 4-8 hours of work per day. Also, results show that farmers earn 57,950 Rwandan Francs (Rwf) per hectare per year (US$ 57.48 from grevillea products (stakes, poles, charcoal, and timber), whereas the mean investment in grevillea production is 54,200 Rwf ha-1 year-1 (US$ 53.76. The net farm income is 3,225 Rwf (US$ 3.2 ha-1 year-1. The net benefit from grevillea product is affected by poor farmer data record as the majority of67% of respondents has not attended any formal education. However, farmers gain additional benefits of US$ 628, US$ 298, and US$ 224ha-1 year-1 from potatoes, maize, and bean, respectively, depending on their crop choice during intercropping with grevillea. The benefit-cost ratio is 1.06, which highlights the modest profitability of growing grevillea on the farm. In addition, soil erosion control, soil fertility increase, landslide prevention, shade provision, microclimate improvement, and biodiversity conservation were reported as ecosystem services of grevillea on the farm. Growth performance of grevillea (diameter at breast height, tree height, and volume) is analyzed in all four villages. The study shows that growing grevillea is profitable for smallholder farmers via tree products and farm benefits, including ecosystem services aspects.

The aeropendulum is a nonlinear system that consists of a rod equipped with a motorized propeller at one of its ends and connected to a pivot at its other end. This pivot receives a torsional moment through the aerodynamic effects generated by the propeller thrust force. From a control point of view, the aeropendulum is a plant that imposes a significant complexity on the design of controllers. In view of that, this system can be used in didactic observations and real applications of control theory concepts. This work presents the model identification and control of an aeropendulum system prototype. The model has as control input the voltage applied to the motor that drives the propeller and the rod angle as system output, measured by an incremental encoder. The identification process was conducted using the ident function of the Matlab® software. Based on the obtained model, an controller was designed to stabilize the system around the operating point, maintaining the rod in a specific position. A square wave was used as a reference for the angular variation of the rod to verify the controller's efficiency in tracking a required angular trajectory. Simulation and experimental tests were conducted to validate the obtained mathematical model and the controller design. The results confirmed that the considered methodology was satisfactory for the studied case.

At present, there are no satisfactory therapeutic drugs for the
functional recovery of spinal cord injury (SCI). We previously
identified a novel peptide (OM-LV20) that accelerated the regeneration
of injured skin tissues of mice and exerts neuroprotective effects
against cerebral ischemia/reperfusion injury in rats . Here, the
intraperitoneal injection of OM-LV20 (1 μg/kg) markedly improved motor
function recovery in the hind limbs of rats with traumatic SCI, and
further enhanced spinal cord repair. Administration of OM-LV20 increased
the number of surviving neuron bodies, as well as the expression levels
of brain-derived neurotrophic factor and its receptor tyrosine receptor
kinase B. In the acute stage of SCI, OM-LV20 treatment also increased
superoxide dismutase and glutathione content but decreased the levels of
malonaldehyde and nitric oxide. Thus, OM-LV20 significantly promoted
structural and functional recovery of SCI in adult rats by increasing
neuronal survival and BDNF and TrkB expression, and thereby regulating
the balance of oxidative stress. Based on our knowledge, this research
is the first report on the effects of amphibian-derived peptide on the
recovery of SCI and our results highlight the potential of peptide
OM-LV20 administration in the acceleration of the recovery of SCI.

Published: January 2024

Background: Left atrial appendage aneurysm (LAAA) is a rare cardiac
disease with potentially life-threatening complications such as systemic
thromboembolism, atrial tachyarrhythmia and cardiac dysfunction.
Currently, early surgical intervention is recommended as the most
suitable treatment to prevent these complications. Case introduction: In
this case report, we describe a 58-year-old female patient admitted to
the hospital with the main symptoms of active dyspnea and recurrent
palpitations for 3 years, which had worsened for a week prior to
presentation. The relevant literature was also reviewed to summarize the
clinical features of LAAA and physical examination and diagnostic
work-ups for patients, including those with no apparent symptoms. These
findings will provide valuable information for further treatment options
and facilitate necessary intervention measures to prevent serious
complications.
Detrended analysis for measuring the spatial correlation

Published: January 2024

Spatial correlation plays an important role in spatial economics.
However, there is still room for improvement of this method. We address
the question of whether the correlation may be trivial consequence of
the trends that are entirely unrelated to spatial adjacency. Application
of this analysis to selected economic data demonstrates that some trends
are not sufficient to account for spatial correlation properties. Then
we modify the spatial adjacency matrix using the detrended
cross-correlation analysis method for stock data. The modified spatial
matrix is introduced to spatial Dubin model. Application of this method
to stock data demonstrates that the spatial DCCA coefficient matrix is
an optional method.

Characteristics of turboexpander unit used to prepare natural gas for transportation
Authors: Chizhov V. V. , Lazarev L. Ya. , Chernykh A. P. , Mikhaylov S. P. 
Published: January 2024

Before being supplied to the transportation pipeline, natural gas must be cleaned from various impurities, with the specified parameters at the inlet to the transportation system — such as composition, mass or volumetric flow rate, pressure, and temperature — to be ensured. To this effect, a gas preparation system is designed, which includes various heat exchange units, cleaning and separation devices, as well as a turboexpander unit (TEU) consisting of a turbine and a coupled compressor.During the operation of this system, the gas parameters are constantly changing due to variations in external and operating conditions, such as the parameters of the ambient air, the gas pressure and flow rate at the wellhead, the composition and the amount of impurities.The gas preparation system therefore almost never operates in the designed conditions, which means that its proper operation requires the knowledge of its characteristics, i.e., the dependencies of the system parameters on external and operational conditions. Besides, the knowledge of the characteristics enables to control the system by affecting its various parameters.The characteristics of the gas preparation system are determined by the characteristics of all of its elements, including the characteristics of the TEU as one of its most important elements.The characteristics of the TEU enable to assess the impact of external conditions on its operating conditions and thus optimize the system's operation during its design stage. They also allow the determination of the parameters for regulating the TEU conditions.A methodology for calculating the TEU characteristics is proposed, an example of the calculation is provided, and analysis of the obtained results is presented.
Perception of events management students in relation to environmental sustainability: case study in Portugal
Authors: Severino Filipe Segurado 
Published: January 2024

Abstract
Tourist-oriented events have relevant impacts on the dimension of environmental sustainability. Without proper planning, those impacts could manifest as harm to the surrounding environment. An effective measure for dealing with these impacts is the appropriate education of event managers. By shaping visitors’ perceptions as they are formed, it is possible for such events to transmit values and knowledge about environmental concerns, leading to future action and the creation of sustainable events that can make a difference.
This research examined event management students’ perceptions of environmental sustainability, their most important values, and whether they incorporated them into their event-organisation practices. With the development of a theoretical framework, an empirical investigation was implemented through a qualitative analysis based on interviews with nine groups of Portuguese students who were in their final academic year. Direct observations were also conducted at six events.
The results revealed a positive correlation between environmental concerns and the academic training of these future event managers. Crucially, behaviours that students exhibit and their beneficial effects lead to their effectiveness in practice, which may be reflected in their future work activity.
Symbolic policy in small towns of Zamojszczyzna region, Poland, in the post-socialist period
Authors: Falski Maciej 
Published: January 2024

Abstract
Small cities have attracted less attention from researchers of transformation processes, although in some countries they are an important part of the social landscape, as they are in Poland. I present the results of research on the public space and symbolic politics in three small towns in Zamojszczyzna, a region in southeastern Poland. All are characterized by interrupted or disturbed historical continuity due to the extermination of their Jewish communities, which made up the majority of the population until World War II. After 1945, the Jewish past was silenced, while the symbolic space was dominated by the memory of the resistance movement. I show in my text that since the 1990s there have been significant transformations in the aforementioned towns. In some of them, firstly, interest in Jewish heritage and efforts to preserve it are becoming more apparent. Second, there is a noticeable shift from commemorating anti-fascism to promoting the so-called struggle against communism, a reflection of the current politics of remembrance at the central level. I argue that the use of cultural heritage in small towns serves largely to gain recognition. Local authorities often use not only elements of the past that fit into national narratives, but also local traditions or even fictional literary heroes, for this purpose.
Satire and subversion in Medieval allegories: “Reynard the Fox” and the Maqamat al-Hamadhani
Authors: Almujalli Hussam 
Published: January 2024

Abstract“Reynard the Fox” and theMaqamat al-Hamadhanidemonstrate the emergence of satire and subversion as important themes in medieval allegories. The authors of both texts utilized the trickster-protagonist to portray dualism in society—especially right versus wrong. In both stories, the trickster figures have two roles: as protagonists and as villains. Both medieval allegories criticize the hypocrisy of their societies, in which mediocrity was praised and excellence was ignored. “Reynard the Fox” and theMaqamat al-Hamadhaniare forms of constructive social criticism that readers desperately need today. An analysis of “Reynard the Fox” and theMaqamat al-Hamadhanicontributes to a deeper understanding of the historical and cultural contexts in which these works emerged, as well as of the literary techniques employed to convey their satirical messages. Hopefully, this article will enrich the study of medieval literature by providing valuable insights into the role of satire and subversion in allegorical narratives.
