On The Controlled Chaos of S-Iteration According to Lyapunov Exponent and Certain Control Mechanisms in Discrete Dynamical Systems
Authors: Sekman Derya , Karakaya Vatan
Published: February 2025

In this paper, our aim is to establish the control mechanism of the iteration process defined as S-iteration in the literature. First of all, it is to determine the dynamics of a system with chaotic property under Siteration. Afterward, we investigate the stability state of the chaotic system under this iteration with the parameters of the S-iteration. In addition, using the chaotic logistic system, we will illustrate the theoretical results in this example in the MATLAB program. Finally, we will examine the periodic state of the S-iteration and investigate the cases in which the periodic behavior is stable or unstable of the S-iteration with the Lyapunov exponent.
Differential–anti-differential equations and their solutions
Authors: Awan Abdul S. , Hussain Sultan
Published: February 2025

In this work, we extend the theory of differential equations to differential–anti-differential equations and solve several types of such equations. To do this, first, we define a derivativeantiderivative operator with a base function and express derivatives and antiderivatives in the form of this operator. Next, we come to differential–anti-differential equations. To solve some of these equations, first, we investigate the Auxiliary equation(s) and find the roots. Roots are then used in the base function to get the exact solutions of the differentialanti-differential equation. The process can be used to solve several well-known differential equations such as Continuity, Heat, Wave, Laplace, Schrodinger, Euler, Blasius, etc. Our technique shows that every elementary function can solve several types of linear and nonlinear ordinary as well as partial differential–anti-differential equations.

MEASURING THE IMPACT OF MOBILE APPLICATIONS
Authors: Nastas Vasile , Bolun Ion
Published: February 2025

Although mobile devices have widespread popularity, allowing, for example, companies to innovate, streamline operations, and maintain a competitive advantage in a rapidly evolving market, the economic impact of using mobile applications (apps) is less researched. In an attempt to improve the state of affairs in the field, this paper provides a classification (based on business domains) and defines models for calculating the costs of developing and using mobile apps in various situations. To evaluate the economic impact of mobile apps, the opportunity of use is argued and the mathematical expressions for calculating the quantitative indices, Net Present Value, Profitability and Internal Rate of Return, eventually in conjunction with the Equivalent Annual Value method, are determined for 12 specific cases of development and use of mobile apps. Also, multiple qualitative indices for measuring the impact of mobile apps are succinctly characterized and systematized. In confirmation of the significant economic and social impact of mobile apps, three implementations of them in various fields are described.

Published: February 2025

To address the excessive accumulation of plastic waste and
incineration ash from domestic refuse, this study explores
their use in tile manufacturing. The goal is to optimize
manufacturing conditions—mixing temperature, mixing
time, and compression force—using the Box-Behnken
design and Response Surface Methodology (RSM). Tiles
were produced at temperatures of 200, 210, and 220°C, with
mixing times of 10, 15, and 20 minutes, and compression
forces of 120, 135, and 150 tons. The results showed high
coefficients of determination (R²) for compressive strength,
flexural strength, and surface abrasion resistance, with
an average error of less than 5%. The optimal conditions
identified were a mixing temperature of 210°C, a mixing time
of 15 minutes, and a compression force of 135 tons, yielding
tiles with a compressive strength of 18.25 MPa, a flexural
strength of 10.10 MPa, and a surface abrasion resistance of
0.02 g/cm².

This study aims to develop sago starch-based bioplastics with
the addition of modifying agents such as acetic acid, chitosan,
and glycerin to improve mechanical properties, elongation,
and biodegradability. The results showed that the optimal
combination was reached at 4% acetic acid and 2% chitosan
concentration, resulting in the highest tensile strength of 8
MPa, elongation at break of 26%, and degradation rate of
70%. At this condition, the bioplastic matrix has an optimal
balance between strength, flexibility, and degradability.
Increasing the acetic acid concentration to 6% caused a
decrease in tensile strength to 4.2 MPa and elongation at
break to 14%, indicating degradation of the matrix structure
due to excess acid. Chitosan also affected the mechanical
properties, where increasing its concentration from 2% to 4%
tended to decrease the elongation at break. The degradation
rate tended to increase with higher concentrations of acetic
acid, reaching 82% at 6% acetic acid concentration with 2%
chitosan, while higher concentrations of chitosan (4%) slowed
down the degradation due to a denser and stronger matrix
structure. Overall, the combination of sago starch, acetic acid,
chitosan, and glycerin produced bioplastics that have improved
mechanical properties, water resistance, and environmental
friendliness, making them a potential alternative to replace
conventional plastics in various industrial applications.
These findings support the development of environmentally
friendly materials that can reduce the negative impacts to the
environment in general and in Papua as the local producer of
Sago.

Authors:   RTEÜ MMF Peyzaj Mimarlığı Bölümü Merkez/RİZE, Türkiye., OĞUZTÜRK Gülcay ERCAN
Published: February 2025

In recent years, increasing population and intense
urbanization have negatively affected urban ecology and
biodiversity, leading to a reduction in urban open and
green spaces. This study evaluates the role of university
campuses in urban areas and the environmental impacts
of land fragmentation using the example of the Kanuni
Campus of Karadeniz Technical University (KTÜ). The study
was conducted in the Kanuni Campus of Karadeniz Technical
University, located in the Ortahisar district of Trabzon in
the Black Sea region. Remote sensing and Geographic
Information Systems (GIS) techniques were used to examine
land cover and temporal land use changes, and the Patch
Analysis, an ArcGIS extension of the Fragstats software, was
applied to determine the level of fragmentation of green
spaces. The results showed that green areas decreased by
48% due to land changes, and the reduction of green areas
negatively affected biodiversity according to the patch
analysis results. This study emphasizes the potential of
universities to preserve and enhance green spaces in cities,
offering strategic recommendations for sustainable urban
planning and aiming to develop solutions for environmental
and health problems encountered in the urbanization
process, along with the socio-economic, cultural, and political
impacts of campuses.
Evaluating The Impact Of Foreign Aid On Stunting Prevalence In Sub-Saharan Africa: An Empirical Analysis Using World Bank Data From 1960-2020.
Authors: Idogho Omokhudu , Anyanti Jennifer , Onyezobi Chinedu , Nwala Anthony ,   Society for Family Health, FCT, Nigeria
Published: February 2025

This study explores the relationship between foreign aid
and stunting prevalence among children under five in SubSaharan Africa (SSA) using a longitudinal dataset from the
World Bank’s World Development Indicators (1960-2020).
Integrating Human Capital Theory and Dependency Theory,
this analysis investigates how net official development
assistance (ODA) impacts stunting, a critical marker of child
health and development, in the context of socioeconomic
and environmental factors. The average prevalence rate
of stunting in SSA is 36.14% ranging between 7.8% in
Seychelles and 56.1% in Burundi. The fixed and random
effects regression models were employed to examine the
data, with a focus on understanding the effects of foreign aid
(net ODA), GDP per capita, literacy rates, access to sanitation,
and water services on child nutrition outcomes. Findings
reveal that while foreign aid exhibits a negative association
with stunting prevalence, this relationship is statistically
insignificant. In contrast, higher GDP per capita and literacy
rates are significantly associated with reductions in stunting
prevalence. These results highlight the importance of aligning
foreign aid strategies with local economic development
and education initiatives to maximize health outcomes.
This study calls for a strategic re-evaluation of foreign aid
policy to promote sustainable, self-sufficient growth within
SSA, addressing both immediate health needs and long-term
development goals.

Perímetros irrigados e a modernização agrícola: uma análise social das intervenções do DNOCS no campesinato piauiense (1970-1990)
Authors: Brito Lucas Ramyro Gomes de , Silva Deusimar Batista da , Rocha Cristiana Costa da
Published: February 2025

Este artigo examina as implicações sociais dos perímetros irrigados implantados pelo Departamento Nacional de Obras Contra as Secas (DNOCS) no Piauí entre 1970 e 1990, com foco nas consequências para os trabalhadores rurais e nas formas de resistência camponesa frente à modernização imposta pelo Estado. A partir de uma análise das fontes históricas do DNOCS em diálogo com as bases teóricas da História Social do Trabalho, como E. P. Thompson e James Scott, problematiza-se a narrativa de progresso associada a esses projetos, apontando para as limitações das políticas desenvolvimentistas que desconsideraram as necessidades dos camponeses. A criação de cooperativas nos perímetros irrigados sobre pressuposto de necessidade de organização da produção agrícola local e combate à seca, impôs um modelo de desenvolvimento incompatível com as práticas tradicionais do campesinato. Esse processo de modernização gerou reações dos camponeses preservando saberes e métodos de cultivo locais, que muitas vezes entraram em conflito com as novas tecnologias e normas impostas pelo Estado. As políticas de combate à seca revelaram as contradições do modelo de desenvolvimento que, em vez de erradicar a pobreza, contribuíram para a perpetuação da exploração e da desigualdade, exigindo uma abordagem mais integrada e sustentável para a convivência com o semiárido.

Elbow stiffness is a relatively common condition and represents a significant disability. A proper clinical history is essential for therapeutic surgical or non-surgical planning.
Purpose: The study aims to investigate the possibility of treating and preventing elbow stiffness.
Material and Methods: A 63-year-old woman was diagnosed with a fracture of the distal humerus and a fracture of the olecranon process. The fractures were treated in the prone position and with a dorsal approach to the elbow. The distal humerus was fixed with medial and dorsolateral locking plates, while the olecranon process was fixed with Webber osteosynthesis. After the operation, the woman required postoperative soft immobilisation for about 30 days. A seven-day treatment was conducted using a combination of Multiwave Locked System (MLS) laser therapy and kinesiotherapy techniques.
Results: On day 1 /T1, after physical examination, the patient was diagnosed with significantly limited range of motion, pain at the end of motion, and swelling of the elbow. On day 7 /T2/ of the seven-day rehabilitation treatment cycle, we observed significant improvement in elbow contracture, range of flexion, reduced swelling, VAS scores, and Mayo Elbow Performance Index scores.
Conclusions: The reported improvement in all the monitored indicators gives us reason to conduct a study on the application of a therapeutic protocol in patients with orthopedic implants of the elbow joint. The challenge in the treatment of postoperative contracture with limitation of movement in the elbow joint requires the inclusion of modern physiotherapeutic methods in its complex treatment.

Malbec is a grapevine variety used for the production of red wines. It is a newly introduced variety in Serbia with less-known production and oenological characteristics in the conditions of the Šumadija wine-growing region.The study includes the analysis of the mechanical parameters of grapes and berries, chemical analysis of the grape juice, microvinification and physicochemical analysis of the wine produced. The average bunch weight was 184.7 g, with the total weight of all berries in the bunch averaging 165,1 g and the average rachis weight of 12,6 g. The grape juice had a sugar concentration of 23,6% and 6 g/l of total acids expressed as tartaric acid. The physicochemical analysis of the wine showed an alcohol content of 12,20% vol, a total extract of 22.10 g/l and 1700.0 mg GAE/l of total phenols. The color intensity was 0.942 and the nuance was 0.66, with red being dominant (49,57%), followed by yellow and blue (32.9 and 17.5% respectively).It can be concluded that Malbec, as a newly introduced variety in the Šumadija region, delivers satisfactory results and has a pronounced oenological potential for producing top-quality colored wines.
IL VOCABOLARIO DELLA CARITÀ E LA FORTUNA DEL VERBO “CARITARE”
Authors: CIONCHIN Afrodita Carmen
Published: February 2025

The paper analyses the extremely rich vocabulary of charity in Italian language, starting from the verb caritare, whose destiny has been peculiar: even though it does not appear in the most important dictionaries of Italian language (De Mauro, Garzanti, Sabatini-Coletti, Treccani, Zingarelli), it has been widely disseminated due to Fabrizio de André’s famous song Khorakhané. The verb caritare was compiled by Prof. Piero Brunello from the Ca’ Foscari University of Venice, in a glossary of terms used in Roma camps in San Giuliano (hosting the so-called Xoraxané Romá, originating from Obilić, near Priština, in Kosovo) and Zelarino (hosting the so-called Dasikané Roma, originating from Šabac, in Serbia), among speakers of Romani and Serbian language, in order to communicate with Venetian and Italian natives, during March-October 1994.

Authors: ENĂCHESCU Mihai
Published: February 2025

With the loss of Arab political and cultural influence, many Arabisms fall out of use and are replaced by words mainly of Latin origin, as cultural borrowings. We have selected an inventory of 25 terms of Arabic origin that designate main courses, deserts or ingredients used in medieval cuisine, the latter being ingredients resulting from preparation, thus excluding natural ingredients such as fruit, vegetables or spices. The paper traces the linguistic history of these words over time, their disappearance, preservation or replacement by other terms, based on data from historical dictionaries and diachronic corpora of the Spanish language.
