29 Study the Effect of Rubbery Phase on Morphology and Rheology Development of PP/PA6/(EPDM: EPDM-g-MA) Ternary Blends
Authors: B. Afsari, M. Hassanpour, M. Shabani
Abstract:
This study aimed to investigate the phase morphology of ternary blends comprising polypropylene (PP), polyamide 6 (PA6), and a blend of ethylene propylene diene monomer (EPDM) and maleic anhydride-grafted EPDM (EPDM-g-MA) in a 70/15/15 ratio. Varying ratios of EPDM to EPDM-g-MA were examined. As the proportion of EPDM-g-MA increased, an interlayer phase formed between the dispersed PA6 domains and the PP matrix. This resulted in the development of a core-shell encapsulation morphology within the blends. The concentration of the EPDM-g-MA component is inversely correlated with the average size of PA6 particles. Additionally, blends containing higher proportions of the EPDM-g-MA rubbery phase exhibited an aggregated structure of the modifier particles. Notably, as the concentration of EPDM-g-MA increased from 0% to 15% in the blend, there was a consistent monotonic reduction in the size of PA6 particles.
Keywords: Phase morphology, rheology, rubbery phase, rubber functionality, ternary blends.

Authors: Elena Carcano, James Ball, Betty Tiko
Abstract:
Carrying capacity refers to the maximum population that a given level of resources can sustain over a specific period. In undisturbed environments, the maximum population is determined by the availability and distribution of resources, as well as the competition for their utilization. This information is typically obtained through long-term data collection. In regulated environments, where resources are artificially modified, populations must adapt to changing conditions, which can lead to additional challenges due to fluctuations in resource availability over time and throughout development. An example of this is observed in hydropower plants, which alter water flow and impact fish migration patterns and behaviors. To assess how fish species can adapt to these changes, specialized surveys are conducted, which provide valuable information on fish populations, sample sizes, and density before and after flow modifications. In such situations, it is highly recommended to conduct hydrological and biological monitoring to gain insight into how flow reductions affect species adaptability and to prevent unfavorable exploitation conditions. This analysis involves several planned steps that help designing appropriate hydropower production while simultaneously addressing environmental needs. Consequently, the study aims to strike a balance between technical assessment, biological requirements, and societal expectations. Beginning with a small hydro project that requires restoration, this analysis focuses on the lower tail of the Flow Duration Curve (FDC), where both hydrological and environmental goals can be met. The proposed approach involves determining the threshold condition that is tolerable for the most vulnerable species sampled (Telestes muticellus) by identifying a low flow value from the long-term FDC. The results establish a practical connection between hydrological and environmental information and simplify the process by establishing a single reference flow value that represents the minimum environmental flow that should be maintained.
Keywords: Carrying capacity, fish bypass ladder, long-term streamflow duration curve, eta-beta method, environmental flow.

Authors: Anastasios Papathanasiou, George Liontos, Athanasios Katsouras, Vasiliki Liagkou, Euripides Glavas
Abstract:
Email remains a crucial communication tool due to its efficiency, accessibility and cost-effectiveness, enabling rapid information exchange across global networks. However, the global adoption of email has also made it a prime target for cyber threats, including phishing, malware and Business Email Compromise (BEC) attacks, which exploit its integral role in personal and professional realms in order to perform fraud and data breaches. To combat these threats, this research advocates for a multi-layered defense strategy incorporating advanced technological tools such as anti-spam and anti-malware software, machine learning algorithms and authentication protocols. Moreover, we developed an artificial intelligence model specifically designed to analyze email headers and assess their security status. This AI-driven model examines various components of email headers, such as "From" addresses, ‘Received’ paths and the integrity of SPF (Sender Policy Framework), DKIM (Domain Keys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting and Conformance) records. Upon analysis, it generates comprehensive reports that indicate whether an email is likely to be malicious or benign. This capability empowers users to identify potentially dangerous emails promptly, enhancing their ability to avoid phishing attacks, malware infections and other cyber threats.

Authors: R. Ananthanarayanan, S. B. Nakula, D. R. Seenivasagam, J. Naua, B. Sharma
Abstract:
Product packaging is a critical component of production, trade, and marketing, playing numerous vital roles that often go unnoticed by consumers. Packaging is essential for maintaining the shelf life, quality assurance, and safety of both manufactured and agricultural products. For example, harvested produce or processed foods can quickly lose quality and freshness, making secure packaging crucial for preservation and safety throughout the food supply chain. In Fiji, agricultural packaging has primarily been managed by local companies for international trade, with gradual advancements in these practices. To further enhance the industry’s performance, this study examines the challenges and constraints hindering the optimization of agricultural packaging practices in Fiji. The study utilizes Multi-Criteria Decision Making (MCDM) tools, specifically Interpretive Structural Modeling (ISM) and Cross-Impact Matrix Multiplication Applied to Classification (MICMAC). ISM analyzes the hierarchical structure of barriers, categorizing them from the least to the most influential, while MICMAC classifies barriers based on their driving and dependence power. This approach helps identify the interrelationships between barriers, providing valuable insights for policymakers and decision-makers to propose innovative solutions for sustainable development in the agricultural packaging sector, ultimately shaping the future of packaging practices in Fiji.

Authors: Nebi Gedik
Abstract:
One of the most common chronic diseases in the world, diabetes is brought on by insufficient insulin production by the pancreas or by inefficient insulin utilization by the body. The disease is linked to the interplay of lifestyle, behavioral and medical circumstances, demographics, and genetic risk factors. Early disease detection is crucial for helping medical professionals with diagnosis or prognosis as well as for creating a successful preventative strategy. Machine learning techniques are utilized for this purpose in order to identify diabetes from medical records. Finding the characteristics or features that provide the best prediction of classification for diabetes detection is the aim of this study. The performance of each feature is compared using the linear discriminant analysis and k-nearest neighbor classifiers. The feature that yields the best classification results has been determined.

Authors: Berk Kılıç, Ömer Aydın, Kerem Mestani, Defne Uzun
Abstract:
In agriculture and farming, pesticides are frequently used to kill off or fend off any pests (bugs, bacteria, fungi, etc.). However, traditional pesticides have proven to have harmful effects on both the environment and the human body, such as hazards in the endocrine, neurodevelopmental, and reproductive systems. This experiment aims to test the effectiveness of organic/bio-pesticides (environmentally friendly pesticides) compared to traditional pesticides. Black pepper and garlic will be used as biopesticides in this experiment. The results support that organic farming applying organic pesticides operates through non-toxic mechanisms, offering minimal threats to human well-being and the environment. Consequently, consuming organic produce can significantly diminish the dangers associated with pesticide intake. In this study, a method is presented to reduce pesticide-related risks by promoting organic farming techniques within organic/bio-pesticide usage.

Authors: J. J. Peña, J. Morales, J. García-Ravelo, J. García-Martínez
Abstract:
It is known that by introducing alternative forms of exponential and logarithmic functions, the Tsallis entropy Sq is itself a generalization of Shannon entropy S. In this work, from a deformation through a scaling function applied to the differential operator, it is possible to generate a q-deformed calculus as well as a q-deformed arithmetic, which not only allows generalizing the exponential and logarithmic functions but also any other standard function. The updated q-deformed differential operator leads to an updated integral operator under which the functions are integrated together with a weight function. For each differentiable function, it is possible to identify its q-deformed partner function, which is useful to generalize other algebraic relations proper of the original functions. As an application of this proposal, in this work, a generalization of exponential and logarithmic functions is studied in such a way that their relationship with the thermodynamic functions, particularly the entropy, allows us to have a q-deformed expression of these. As a result, from a particular scaling function applied to the differential operator, a q-deformed arithmetic is obtained, leading to the generalization of the Tsallis entropy.

Authors: Stephan P. Barkhuizen, Deon Greyling, Ryan J. Miller
Abstract:
The accurate determination of the engineering parameters of soil is necessary for the design of geotechnical structures, such as Tailings Storage Facilities. The shear strength and saturated permeability of soil and tailings samples obtained from 14 sites located in the copper belt in the Democratic Republic of the Congo have been tested at six commercial soil laboratories in South Africa. This study compiles a database of the test results proved by the soil laboratories. The samples have been categorised into clay, silt, and sand, based on the Unified Soil Classification System, with tailings kept separate. The effective friction angle (Φ’) and cohesion (c’) were interpreted from the stress paths, in s’:t space, obtained from triaxial tests. The minimum, lower quartile, median, upper quartile, and maximum values for Φ’,c’, and saturated hydraulic conductivity (k) have been determined for the soil sample. The objective is to provide statistics of the measured values of the engineering properties for the Tailings Storage Facilities (TSFs) borrow material, foundation soils and tailings of this region.

Abstract:
This research focuses on enhancing geotechnical surveying for foundation design through the spatial interpolation of intermediate soil properties. Traditional geotechnical practices rely on discrete data from borehole drilling, soil sampling, and laboratory analyses, often neglecting the continuous nature of soil properties and disregarding values in intermediate locations. This study challenges these omissions by emphasizing interpolation techniques such as kriging, inverse distance weighting, and spline interpolation to capture the nuanced spatial variations in soil properties. The methodology is applied to geotechnical survey data from two construction sites in Astana, Kazakhstan, revealing continuous representations of Young's modulus, cohesion, and friction angle. The spatial heatmaps generated through interpolation offered valuable insights into the subsurface environment, highlighting heterogeneity and aiding in more informed foundation design decisions for considered cites. Moreover, intriguing patterns of heterogeneity, as well as visual clusters and transitions between soil classes, were explored within seemingly uniform layers. The study bridges the gap between discrete borehole samples and the continuous subsurface, contributing to the evolution of geotechnical engineering practices. The proposed approach, utilizing open-source software geographic information systems, provides a practical tool for visualizing soil characteristics and may pave the way for future advancements in geotechnical surveying and foundation design.

Abstract:
To better understand the prevalence of neurological symptoms associated with COVID-19, several factors, such as age, gender, and comorbidity, are explored to create a more holistic understanding of the impact of COVID-19. After meeting inclusion and exclusion criteria, 111 patients admitted to Ibne Sina Hospital were recruited between October 2021 and February 2022. A descriptive statistical analysis was conducted to summarize patients most often encountered signs and symptoms concerning the above parameters. Out of 111 patients, a significant proportion of symptoms occurred in patients aged 40-60 years, with Dysgeusia being the most widespread (75.5%), followed by Encephalitis (45.9%), Guillain Barre Syndrome (GBS) (28.8%), Encephalopathy (18.9%), and Ischemic Stroke (6.3%). These were most prevalent in hypertensive individuals (46%) and Diabetes Mellitus (31%). In asthmatic individuals, they are the least prevalent (10.8%). Despite the predominance of neurological manifestations, the present scientific literature cannot demonstrate a definitive causal association between the symptoms and the virus. This study carefully ensures a link between age, gender, and comorbidity, along with the prevalence of neurological manifestations of COVID-19. For a comprehensive treatment plan, a holistic understanding of symptoms is critical.

Authors: Moustafa Osman Mohammed
Abstract:
The spatial-economic modeling database is crucial in understanding economic network structures for social development. Sustainability within spatial-economic model focuses on encouraging green businesses to align with Earth’s systems. The natural exchange patterns of ecosystems exhibit consistent and periodic cycles to maintain energy and material flows in systems ecology. When network topology influences formal and informal communication to function in systems ecology, ecosystems are hypothesized to influence the basic level of spatial sustainable outcomes (i.e., project compatibility success). These referred instrumentalities impact with various aspects of the second level of spatial sustainable outcomes (i.e., participant social security satisfaction). The sustainability outcomes are modeled using composite structure based on a network analysis model to calculate the prosperity of panel databases for efficiency value from 2005 to 2025. The spatial database structure represents the state-of-the-art of value-orientation impact and corresponding complexity of sustainability issues for collecting a consistent database in approach structure of spatial-economic-ecological model, developing a set of sustainability indicators, enabling quantification impact using value-orientation policy and demonstrating spatial structure reliability. The structure of the spatial-ecological model is established for management schemes from the perspective of pollutants of multiple sources through the input–output criteria. These criteria evaluate the spillover effect to conduct Monte Carlo simulations and sensitivity analysis in a unique spatial structure. The balance within “equilibrium patterns,” such as collective biosphere features, is measured using a composite index of many distributed feedback flows. This index has a dynamic structure related to physical and chemical properties for gradual prolongation to incremental patterns. While these spatial structures argue from ecological modeling of resource savings, static loads are not decisive model from an artistic/architectural perspective. The model attempts to unify analytic and analogical spatial structure for the development of urban environments in a relational database, using optimization software to integrate spatial structure where the process is based on the engineering topology of systems ecology.

Authors: Ilma Robo, Saimir Heta, Gerhard Nokaj
Abstract:
The method of treatment and the treatment protocols of apical periodontitis are now known, but the ongoing debate remains on whether or not prescription antibiotics should be given to patients suffering from this type of pathology. In fact, as an indication for prescribing antibiotics, this type of pathology remains between clinical indication and contraindication. This article is of the short-communication type and the sole purpose of analyzing the clinical picture of apical periodontitis and the fact that the appearance and extent of this pathology in the periapex area passes the stage when the host or the immune cells of the organism of the affected individual, react against bacterial factors. It is possible to avoid making decisions on the prescription of systemic antibiotics based on literary sources. In some cases, research in this field about this pathology even indicates endodontic rinsers or irrigants, such as chlorhexidine in typical cases, mainly in persistent apical periodontitis. In times when bacterial resistance is a hot topic in some fields of scientific research, it is important to divide dental pathologies of bacterial origin into those when systemic antibiotic prescriptions must be given and those when every clinical issue is resolved only with endodontic root canal treatment. Even certain sources of published literature show the specifics of the most effective antibiotics against the bacterial flora causing the pathology of apical periodontitis.

Authors: Rickard Grassman
Abstract:
In this paper, Lacanian theory will be used to illustrate the way discourses interact with the material by way of reifying antagonisms to shape our sense of identities in and around organizations. The ability to ‘sustain the loss’ is, in this view, the common structure here discerned in the very texture of a discourse, which reifies ‘lack’ as an ontological condition into something contingently absent (loss) that the subject hopes to overcome (desire). These fundamental human tendencies of identification are illustrated in the paper by examples drawn from history, cinema, and literature. Turning to a select sample of empirical accounts from a management consultancy firm, it is argued that this ‘sustaining the loss’ operates in discourse to enact identification in an organizational context.
Keywords: Lacan, identification, discourse, desire and loss.

Authors: Mohammad Borhani, Ahmad Jamshidzaei, Mehdi Koohsari
Abstract:
The study of climate has captivated human interest throughout history. In response to this fascination, individuals historically organized their daily activities in alignment with prevailing climatic conditions and seasonal variations. Understanding the elements and specific climatic parameters of each region, such as precipitation, which directly impacts human life, is essential because, in recent years, there has been a significant increase in heavy rainfall in various parts of the world attributed to the effects of climate change. Climate prediction models suggest a future scenario characterized by an increase in severe precipitation events and related floods on a global scale. This is a result of human-induced greenhouse gas emissions causing changes in the natural precipitation patterns. The present study focused on examining the trend of monthly, seasonal, and annual precipitation in Sistan and Baluchestan provinces. The study employed data obtained from 13 precipitation measurement stations managed by the Iran Water Resources Management Company, encompassing daily precipitation records spanning the period from 1997 to 2016. The results indicated that the total monthly precipitation at the studied stations in Sistan and Baluchestan province follows a sinusoidal trend. The highest intense precipitation was observed in January, February, and March, while the lowest occurred in September, October, and then November. The investigation of the trend of seasonal precipitation in this province showed that precipitation follows an upward trend in the autumn season, reaching its peak in winter, and then shows a decreasing trend in spring and summer. Also, the examination of average precipitation indicated that the highest yearly precipitation occurred in 1997 and then in 2004, while the lowest annual precipitation took place between 1999 and 2001. The analysis of the annual precipitation trend demonstrates a decrease in precipitation from 1997 to 2016 in Sistan and Baluchestan province.

Abstract:
This study investigates the prevalence and diversity of hard tick species infesting sheep in the Ivanki region of Semnan Province over 2023-2024. As significant ectoparasites of livestock, ticks can cause anemia and economic losses by feeding on animal blood, and they act as vectors for various diseases transmissible to humans. To assess tick status, 10 sheep from each of 10 farms were randomly selected, and samples were collected from various body parts, including the ears, head, under the tail, anus, and udder, and subsequently preserved in 70% alcohol. Species identification was conducted using Wall and Shearer’s identification key (2001). Results showed a 39% infestation rate among sheep, with identified tick species including Hyalomma anatolicum anatolicum (46.9%), Hyalomma anatolicum excavatum (16%), Hyalomma marginatum (30.9%), and Hyalomma asiaticum asiaticum (7%). These findings are consistent with similar studies in Iran and worldwide, although some differences were noted, likely due to variations in climate, altitude, vegetation, and rainfall. Given the role of ticks in transmitting zoonotic diseases, these results can aid in designing tick control programs. Educating livestock owners on the importance of tick control, including spraying and improving livestock management, could effectively manage tick populations.

Authors: Yen -Fen Shen, Meng -Fan Li
Abstract:
The study aims to investigate the effect of full-body vertical rhythmic training on fatigue, physical activity, and quality of life among middle-aged and elderly hemodialysis patients. The study adopted a quasi-experimental research method and recruited 43 long-term hemodialysis patients from a medical center in northern Taiwan, with 23 and 20 participants in the experimental and control groups, respectively. The experimental group received full-body vertical rhythmic training as an intervention, while the control group received standard hemodialysis care without any intervention. Both groups completed the measurements by using "Fatigue Scale", "Physical Activity Scale" and "Chinese version of the Kidney Disease Quality of Life Questionnaire" before and after the study. The experimental group underwent a 10-minute full-body vertical rhythmic training three times per week, which lasted for eight weeks before receiving regular hemodialysis treatment. The data were analyzed by SPSS 25 software, including descriptive statistics such as frequency distribution, percentages, means, and standard deviations, as well as inferential statistics, including chi-square, independent samples t-test, and paired samples t-test. The study results are summarized as follows: 1. There were no significant differences in demographic variables, fatigue, physical activity, and quality of life between the experimental and control groups in the pre-test. 2. After the intervention of the “full-body vertical rhythmic training,” the experimental group showed significantly better results in the category of "feeling tired and fatigued in the lower back", "physical functioning role limitation", "bodily pain", "social functioning", "mental health", and "impact of kidney disease on life quality." 3. The paired samples t-test results revealed that the control group experienced significant differences between the pre-test and post-test in the categories of feeling tired and fatigued in the lower back, bodily pain, social functioning mental health, and impact of kidney disease on life quality, with scores indicating a decline in life quality. Conversely, the experimental group only showed a significant worsening in bodily pain and the impact of kidney disease on life quality, with lower change values compared to the control group. Additionally, there was an improvement in the condition of "feeling tired and fatigued in the lower back" for the experimental group. The intervention of the “full-body vertical rhythmic training” had a certain positive effect on the quality of life of the experimental group. While it may not entirely enhance patients' quality of life, it can mitigate the negative impact of kidney disease on certain aspects of the body. The study provides clinical practice, nursing education, and research recommendations based on the results and discusses the limitations of the research.

Authors: Duško Salemović, Aleksandar Dedić, Matilda Lazić, Dragan Halas
Abstract:
The paper presents the conceptual solution for the final cooling of the chocolate dressing of biscuit in one confectionary factory in Serbia. The proposed concept solution was derived from the desired technological process of final cooling of biscuit and the required process parameters that were to be achieved, and which were an integral part of the project task. The desired process parameters for achieving proper hardening and coating formation are: the exchanged amount of heat in the time unit between the two media (air and chocolate dressing), speed of air inside the tunnel cooler and the surface of all biscuits in contact with the air. These parameters were calculated in the paper. The final cooling of chocolate dressing on biscuits could be optimized by changing process parameters and dimensions of the tunnel cooler, and looking for the appropriate values for them. The accurate temperature predictions and fluid flow analysis could be conducted by using heat balance and flow balance equations having in mind theory of similarity. Furthermore, some parameters were adopted from previous technology process, such as: inlet temperature of biscuits and input air temperature. A thermal calculation was carried out and it was demonstrated that the percentage error between the contact surface of the air and the chocolate biscuit topping, which is obtained from the heat balance and geometrically 0.67%, which is very good agreement. This enabled quality of the cooling process of chocolate dressing applied on biscuit and hardness of its coating.

Authors: Evgeny N. Zakharin, Bartosz Majewski
Abstract:
Foaming polyurethane is a ground improvement technology that is increasingly used for foundation stabilization with differential settlement and controlled foundation structure lifting. This technology differs from conventional mineral grout due to its injection composition, which provides high-pressure expansion quickly due to a chemical reaction. The technology has proven efficient in the typical geological conditions of the United Arab Emirates. An in-situ trial foundation load test has been proposed to objectively assess the deformative and load-bearing characteristics of the soil after injection. The article provides a detailed description of the experiment carried out in field conditions. Based on the practical experiment's results and its finite element modeling, the deformation modulus of the soil after treatment was determined, which was more than five times higher than the initial value.

Abstract:
Pervasive computing is a growing research field that aims to acknowledge human physical life routines (HPLR) based on body-worn sensors such as MEMS (Micro-Electro-Mechanical Systems) sensors-based technologies. The use of these technologies for human activity recognition is progressively increasing. On the other hand, personalizing human life routines using numerous machine-learning techniques has always been an intriguing topic. In contrast, various methods have demonstrated the ability to recognize basic movement patterns. However, it still needs to be improved to anticipate the dynamics of human living patterns. This study presents state-of-the-art techniques for recognizing static and dynamic patterns and forecasting those challenging activities from multi-fused sensors. Furthermore, numerous MEMS signals are extracted from one self-annotated IM-WSHA dataset and two benchmarked datasets. First, raw data were processed with z-normalization and denoiser methods. Then, we adopted statistical, local binary pattern, auto-regressive model, and intrinsic time scale decomposition major features for feature extraction from different domains. Next, the acquired features are optimized using maximum relevance and minimum redundancy (mRMR). Finally, the artificial neural network is applied to analyze the whole system's performance. As a result, we attained a 90.27% recognition rate for the self-annotated dataset, while the HARTH and KU-HAR achieved 83% on nine living activities and 90.94% on 18 static and dynamic routines. Thus, the proposed HPLR system outperformed other state-of-the-art systems when evaluated with other methods in the literature.
Keywords: Artificial intelligence, machine learning, gait analysis, local binary pattern, statistical features, micro-electro-mechanical systems, maximum relevance and minimum redundancy.

Authors: Jingxian An, Brent Young, Paul Kilmartin, Wei Yu
Abstract:
Australia and New Zealand are neighbouring countries in the New World wine industry, and their Pinot noir wines have gained both production and reputation in recent years, competing in the international market. Consumer perception is heavily influenced by wine expertise, which plays a significant role in shaping their perceptions. This study aims to investigate the effects of country of origin and wine expertise on consumer perceptions. The results indicate that consumers' perceptions of Pinot noir wines' astringency, sourness, sweetness, clarity, and bitterness are impacted by both country of origin and wine expertise. Of the five sensory attributes, sourness was found to have a more significant influence on consumer perceptions, while clarity had a minimal impact. Additionally, the study found that country of origin had a greater impact on consumer perceptions than wine expertise.
Keywords: Australia, country of origin, consumer perception, New Zealand, wine expertise.

Authors: Jonathan M. Watt, Regina L. Sturiale
Abstract:
The linguistic idiosyncrasies of prison populations have been studied with great interest by scholarly and popular writers alike whose interests range from curiosity to a disciplined understanding of its function. This paper offers a formalized nomenclature for the four relevant terms (slang, jargon, argot, and cant) and brings together key sociolinguistic concepts such as domain and register with research on institutional dynamics as well as culture and identity. It presents a fresh body of data drawn from interviews with prison staff in the Northeast (NE) and with awareness of selected publications. The paper then draws a correlation between a person’s competence in prison antilanguage and their status as part of the in-group. This is a distinctive marker of identification that is essential to inmate survival and staff effectiveness.
Keywords: Argot, cant, domain, jargon, slang, sociolinguistics.

Authors: A. Fogliata, L. Martiniello, A. Ambretti
Abstract:
The significance of balance and stability in physical education among adolescents is well-established. This study aims to assess the efficacy of centering, which employs intra-abdominal pressure (IAP) in line with the Sincrony Method, in optimizing balance and reducing perceived stress. A 6-week intervention was conducted on a sample of adolescents, divided into a control group and an experimental group that incorporated the centering into their physical education program. The Stork Balance Test and the Perceived Stress Scale (PSS) were used to measure changes. Findings revealed a significant enhancement in the balance of both the dominant and non-dominant limbs in the experimental group compared to the control group. Moreover, the PSS test indicated a reduction in perceived stress within the experimental group. Integrating the centering technique into physical education programs can lead to substantial improvements in adolescents' balance and stability, in addition to a reduction in perceived stress levels. These findings suggest the need for further research on broader populations to solidify these pivotal outcomes.
Keywords: Adolescents, physical education, balance, centering, intra-abdominal pressure.

Authors: Thomas E. Portegys
Abstract:
An animal behavior problem is presented in the form of a nest-building task that involves two cooperating virtual birds, a male and female. The female builds a nest into which she lays an egg. The male's job is to forage in a forest for food for both himself and the female. In addition, the male must fetch stones from a nearby desert for the female to use as nesting material. The task is completed when the nest is built, and an egg is laid in it. A goal-seeking neural network and a recurrent neural network were trained and tested with little success. The goal-seeking network was then enhanced with “place cells”, allowing the birds to spatially navigate the world, building the nest while keeping themselves fed. Place cells are neurons in the hippocampus that map space.
Keywords: Artificial animal intelligence, artificial life, goal-seeking neural network, nest-building, place cells, spatial navigation.
