Authors: Shahzad Arfan , Anwar Yasmin , Nadeem Muhammad , Shair Waqas
Published: December 2024

The advancement in technologies has changed the picture of today’s economy. Cryptocurrency is the most trending currency nowadays. The form of cryptocurrency that is most commonly used in trading is Bitcoin. Since 2016, continuous fluctuations have been observed in the price of Bitcoin. The objective of the current study is to classify the strong predictor of Bitcoin’s price fluctuations and the associations of all these variables with each other. The price of several variables is selected as independent variables, including oil, VIX index, and US dollars. The price values for all study variables are collected for one year daily. The study findings indicated that lag 2 in the VAR model is the optimum lag for the model using HQIC and SBIC criteria, so today’s price depends on the previous two days’ price of independent variables. The correlation results indicated that the previous two-day price of EURO predicts the BTC’s today’s price. A negative association is found between VIX and BTC. It is indicated that a 1 percent increase in the price of the VIX index will lead to the 60 decreases in BTC’s today price. The study also showed that it is not the price of BTC that forecasts today’s worth of BTC, but it is the prices of VIX, euro, and oil that can predict today’s price of BTC.
Wacana Program Bansos untuk Korban Judi Online dalam Tinjauan Al-Maṣlaḥaḥ Al-Mursalah Perspektif Wahbah Az-Zuḥaili

Published: December 2024

The Minister of Human Development and Cultural Affairs, Muhadjir Effendy, opened the opportunity for victims of online gambling to be included in Social Welfare Integrated Data (DTKS) so that they could receive social assistance. The victims are family members or close relatives who have been financially harmed by online gambling perpetrators. This programme sparked support and opposition from various circles. The emergence of these differing views is influenced by varying perspectives on assessing the maṣlaḥaḥ (public interest) of the program. Indeed, in the context of Islamic law, maṣlaḥaḥ can be used as a basis for legitimizing something, a method known as al-maṣlaḥaḥ al-mursalah. However, according to Wahbah az-Zuḥaili in Uṣūl al-Fiqh al-Islāmi, the measure of maṣlaḥah is not human logic but the legitimacy of syariat regarding a particular form of maṣlaḥah. According to Wahbah az-Zuḥaili, human reasoning will always differ in assessing maṣlaḥah, as seen in the differing opinions of some scholars regarding the maṣlaḥah of social assistance programs. The aim of this study is to analyze the discourse surrounding the social assistance program for victims of online gambling from the perspective of al-maṣlaḥaḥ al-mursalah, according to Wahbah az-Zuḥaili. To achieve this goal, the research method used was qualitative, with a library research approach. The data collection technique involves reviewing various literature, including classical and contemporary scholars' books, scientific articles, and other relevant sources. The results of this study indicate that this program is in line with the standards of the concept of al-maṣlaḥaḥ al-mursalah, as outlined by Wahbah az-Zuḥaili.

ZERO-Kunst und Mode
Authors: Vinken Barbara
Published: December 2024

ZERO war ein Neuanfang. Ende der 1950er-Jahre stellten Heinz Mack, Otto Piene und Günther Uecker die tradierte Kunst infrage. Das gilt auch für die Mode. Die renommierte Expertin Barbara Vinken zeigt, dass beide unter einer Decke stecken, ein konzeptuelles Interesse teilen und mal spielerisch und witzig, mal verrückt und verschoben Konventionen über den Haufen werfen. Stets das Performative in der Kunst betonend, zeigt sich hier die Verbindung von Objekten aus Licht und Bewegung: von den Modekreationen von Lucio Fontana und Yves Klein bis hin zum »ZERO-Kleid«. Die 2008 in Düsseldorf gegründete ZERO foundation widmet sich mit dieser Publikation dem gänzlich unerforschten Thema. Aus interdisziplinärer Perspektive werden Kunst und Dokumente der ZERO-Avantgarde zusammengetragen, kontextualisiert und vorgestellt.

Published: December 2024

This study focuses on the pressing problem of water pollution in locations such as Banjarmasin, where sasirangan artisans have difficulties due to contamination from industrial wastewater. The objective is to assess the efficiency of the PLISS system in treating sasirangan production wastewater, with a specific focus on the impact of electrocoagulation duration on treatment results. This study aims to address the lack of sustainable wastewater management practices for small-scale craft enterprises. Using a quasi-experimental design, the samples were divided into treatment and control groups. Various parameters were assessed before and after treatment using electrocoagulation, in accordance with the requirements set by South Kalimantan Provincial Regulation No. 036 of 2008. The data was analyzed using statistical methods. The PLISS system achieved substantial decreases in pollutant levels by post-treatment pH adjustment. Significant reductions were noted in BOD5, COD, TSS, Phenol, Total Chromium, Ammonia, Oil & Grease, and Sulfide, thereby satisfying the standards for wastewater quality. The study highlights the effectiveness of the PLISS system in treating wastewater from sasirangan manufacturing using electrocoagulation. It suggests optimizing the length of electrocoagulation and investigating the system's suitability for small-scale companies. It is essential to recognize the limits of the study, such as its small scope and the requirement for long-term sustainability research, in order to make progress in developing wastewater treatment solutions.

Authors: Zain Muhammad Hilman , Khair Abdul , Haris Abdul
Published: December 2024

In the Banjar Regency of Indonesia, where merely 72.55% of the population has access to potable water and river water turbidity (53 NTU) above national regulations (<3 NTU), the identification of effective and sustainable water treatment methods is imperative. This study examined the effectiveness of locally-sourced Nagara bean (Vigna unguiculata subsp. cylindrica) powder as a natural coagulant in water treatment. Employing a posttest-only control group experimental design, we evaluated several doses (400, 600, and 800 mg/L) and contact durations on river water samples, with turbidity reduction as the principal outcome measure. Statistical analysis employing Two-way ANOVA and post-hoc Tukey HSD testing indicated that optimal performance occurred at a dosage of 600 mg/L with a contact period of 60 minutes, yielding a 54.7% reduction in turbidity (from 77.46 NTU to 35.1 NTU). This performance exceeded that of other natural coagulants, including tamarind and Moringa seeds. The research revealed a non-linear dose-response relationship, emphasizing the intricacy of the coagulation process and the necessity for accurate dosage. The findings indicate that Nagara bean powder presents a sustainable and economical substitute for chemical coagulants in water treatment in areas with inadequate infrastructure; nevertheless, additional research is required to investigate wider dosage ranges and diverse water quality circumstances.

Authors: Az Zahra Nisfia , As Zulfikar Ali , Junaidi Junaidi
Published: December 2024

Coal mining in South Kalimantan, Indonesia, is economically vital yet poses environmental and health hazards, particularly in residential zones. This study investigated the correlation between coal transport volume and dust settling concentrations in residential areas to solve issues related to dedicated coal transportation routes. The study assessed coal transportation volume and dust concentrations in the field by observational analytical techniques and a cross-sectional survey methodology. Dust Fall Collectors were installed at four coal transportation route sites for a duration of 30 days, with measurements taken at six sampling intervals. Dust concentrations exhibited a positive correlation with traffic volume, with highest levels (1000.18 tons/km²/month) coinciding with maximum traffic volume (222.4 PCU). Daily traffic and dust levels fluctuated due to factors such as rainfall, which diminished dust concentrations. The research indicated that mixed-use roadways and the absence of natural barriers exacerbate dust pollution. These findings underscore the imperative for adaptive dust suppression, traffic regulation, and natural barriers. The study indicates that enhanced regulations and practices are essential to alleviate the adverse impacts of coal mining on public health and the environment in residential areas adjacent to transportation routes, offering policymakers and environmental managers in mining regions critical insights.

Published: December 2024

This paper explores initiation ceremonies that are known by different names and are commonly observed in many traditions both in Africa and beyond. In keeping up with tradition and heritage, many communities in Africa practice initiations as a rite of passage to adulthood for their youths. In Zambia, the ceremony is known as Kulamba for the Chewa people. Contextually, it is a thanks giving festival for the harvest in a particular year; no wonder it has survived many years as a traditional practice for the Chewa people.
This paper postulates that there are gender issues that have been undermined and need to be interrogated in order to strike a balance between indigenous practices as well as gender equality advances. This is a qualitative phenomenological paper, designed with the quest to engender and understand the meaning of individual women lived experiences about the Kulamba initiation ceremony of the Chewa people of Zambia. The paper concentrates on exploring the meaning of the Kulamba ceremony (embedded with it the Indigenous Knowledge System) to women’s lives in Zambia only. In support with Gerring on case studies: “as a systematic process of analyzing a particular person, group or detailed description of setting and situation” is found appropriate for this paper. Whilst, normally; findings from case studies are not generalizable to the larger population, here, the situation is different because the interpretation and meaning of gender embedded in the Kulamba initiation ceremony is applicable in different contexts to people that speak and practice the same culture.

Published: December 2024

In this paper, the design and development of an equivalent dish (center) for heating water using available materials was presented. Comparative studies were conducted for reflective and absorbent surfaces, and the best of them was chosen to form the solar concentrator unit. Solar concentrator units were installed in the College of Science, Al-Ajilat - Libya, and center variables such as two temperatures were measured. The entry and exit of water, the intensity of direct radiation on the center opening, and the environmental variables surrounding the center such as ocean temperature and wind speed, and the flow rate was fixed at “L/h 15”
The period of measuring the variables lasted for 6 months, and the available energy, the extracted energy, and the instantaneous, hourly, and daily efficiency of the solar center were calculated. At every quarter hour of the measurement hours, it became clear from the measured quantities that the variables change with the change in the intensity of the solar radiation falling directly on the center, where it takes the value. The maximum is at noon. It was also noted that the average efficiency for the day for a moving center was (29)%, compared to the fixed center, which was (6)%, and as for a glass-coated pipette, the efficiency was (39)% Compared to the absorbent without a coating, which was (30)%, and the absorbent coated with epoxy (49%), compared to the other types of coatings, which were (45,39,28) respectively, and for the mirror reflector, the efficiency was (58)%, and compared to the following reflectors, which were ( (47.41%). It was also noted that the temperature of the hot water reached (100℃), and from the results, in order for the center to give the largest amount of heat, it must follow the movement of the sun, and the absorber must be surrounded by a glass casing, and painted with a selective paint such as epoxy.

Published: December 2024

In order to reveal the influence of gyroscope effect and structure parameters on the modal frequency and critical speed of the rotor system in disc centrifuge for separation of bioengineering. Based on the rotor rigid body dynamics, the fixed-point gyroscope motion of the rotating spindle of the disc centrifuge was analyzed. Establishing a finite element dynamic model for the rotor system of a disc centrifuge, taking into account the gyroscopic moment caused by the rotational inertia of the rotor disk and the elastic support of the bearings. We calculated the gyroscopic moment and the analytical expression of critical speed. Analyzing the quantitative relationship between the gyroscope effect, bearing support stiffness, drum material density and the critical speed of the rotor system. The results show that the calculated value of finite element is close to the measured value. The influence of gyroscopic force on the vibration characteristics of rotor system for dish centrifuge cannot be ignored. The critical speeds of the rotor system increase with the increase of elastic support stiffness, while the first critical speed decreases with the increase of drum density, but the second critical speed increases with the increase of drum density. These studies provide a theoretical reference for the dynamic response, structural design and dynamic balance of disc centrifuge.
Gender Social Norms among Internal Migrant Communities in South-West Nigeria
Authors: Silva Asagba Omolola , Duruji Moses Metumara , Chidozie Felix , Osimen Goddy Uwa
Published: December 2024

This study delves into the complex relationship between migration, gender social norms, and child marriage within internal migrant communities in Southwest Nigeria. Existing research has demonstrated that the dynamics of child marriage and migration are intricately interwoven and contingent upon specific contextual factors. This relationship is further nuanced by the dual pressures of conflict and forced displacement, which can exert both upward and downward influences on child marriage practices. Drawing from the prevalence of child marriage across multiple boards, specific normative factors were identified, such as a girl's chastity as a means to preserve family honour, a preference for male education and opportunities, the perception of girls as a financial burden leading to early marriage, and the societal view of girls primarily in roles as wives and mothers. These norms constrain girls' participation in decision-making processes and reinforce their subservient roles. The intersecting impact of these social norms on poverty and prolonged insecurity contributes to the perpetuation of child marriage. Insights from studies on legalities surrounding the permissible age for marriage underscore the significant sway of societal norms in determining marriage timing. These insights provide a foundation for the development of interventions and policies promoting gender equality and safeguarding the rights of individuals affected by child marriage. Despite a growing volume of research on child marriage, there remains a research gap within humanitarian contexts, particularly migration. This study seeks to address this gap by exploring the complex interplay between migration, gender, and social norms in shaping child marriage practices, specifically within the Nigerian context.

Neural Networks in Astrophysics and Plasma Physics: Transformers, PINNs, KANNs, and all that
Authors: Kounchev O. , Simeonov G.

Recently, new approaches have been developed for the numerical solution of problems in Dynamical systems and boundary value problems for Partial differential equations, which are based on the very general models of the type of Neural networks. Those of them who respect the physical background of the processes are called Physics Informed models (PINNs); their respect to the physics is expressed by means of the properly formulated loss functional which uses explicitly the differential equations and the boundary value conditions in a regularized fashion. Despite not excelling in terms of performance (accuracy and training computing time), PINNs present a compelling alternative for addressing challenges that prove difficult for traditional methods, such as inverse problems or parametric partial differential equations (PDEs).Things have gone much further by trying to mimic in other areas the revolutionary innovation in NLP (especially, in the Large Language models - LLMs) – the so-called Transformers. However, their applicability is still restricted to processes described by Dynamical systems, i.e. where the time is present in the equation.We will give a short overview of the above newest developments in the area of AI, and to some successful applications to Astrophysics and Plasma Physics. - FULL TEXT available in PDF.

AbstractHere we want to investigate X-shaped radio galaxy 3C 315, which is a FRII source, but it lies very close to the FRI/FRII borderline. We used publicly available data from Leahy’s atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED) in order to investigate its flux density, as well as the spectral index distribution. We obtained spectral index distributions between the frequencies: 1417 MHz - 2695 MHz and 1646 MHz - 2695 MHz. Our conclusion is that the synchrotron radiation is the dominant radiation mechanism over most of the area of 3C 315. Because of very poor hotspots (i.e. warmspots) we investigated which part of the source represents more active regions. The results of this study would be helpful to understand the evolutionary process of the galaxy 3C 315. - FULL TEXT available in PDF.
New opportunities for COST participants – actions networking tools and examples of the national funding schemes
Authors: Mijić Z.R. , Marinković B.P.
Published: December 2024

As the oldest intergovernmental funding organization in Europe COST (the European Cooperation in Science and Technology) facilitates networking among academics and innovators in order to increase Europe's ability to address scientific, technical, and societal concerns (Marinković and Mijić 2022). According to the study (Seeber et al., 2022a), participation in COST program considerably increases researchers' scientific co-publications, therefore advancing their professional careers. The findings demonstrate a 55% average increase in co-publications among active COST action participants as compared to the proposed network of the researchers of non-founded actions. This increase in collaborative co- publications is not at the expense of non-collaborative ones, resulting in a net gain in scientific production. Keeping in mind that the impact of the actions lasts beyond their lifetime, involvement in COST networking activities significantly improves researchers' productions and experience thus increasing their capacity for long-term collaborations (Seeber et al., 2022b). This is especially important for early-career researchers, as around 42% of COST action members in 2023 are young researchers. (Mijić and Marinković, 2024a).Over the last several years running the COST action have become more and more competitive (Mijić and Marinković, 2024b). The reported success rate of the action proposals for the last open call OC-2023-1 was 11.5%. Since there is a clear benefit of scientific community involved in research network, several European countries established additional national funding to support research projects originating from successful ongoing COST Actions.In this study, within proposed mini-project, we will discuss the new opportunities for COST participants through the actions networking tools focusing on young researchers’ and ITC (Inclusiveness Target Countries) conference grants entering into force in November 2024. In addition, new technical annex, ... - FULL TEXT available in PDF.
Electrical Breakdown in trans-1,3,3,3-Tetrafluoropropene HFO1234ze(E)

Published: December 2024

Hydrofluoroolefins, unsaturated organic compounds developed as "fourth generation" refrigerants, possess only 0.1% of the Global Warming Potential (GWP) of hydrofluorocarbons (HFCs) and have negligible Ozone Depletion Potential (ODP). Their excellent eco-friendly properties make them suitable for use in air conditioning systems and they are also considered to be potential replacements for SF6 in dielectric applications. In recent years, trans-1,3,3,3- Tetrafluoropropene (HFO1234ze(E)) has garnered the research community's interest due to its applications in medium and high voltage gas-insulated transmission and distribution equipment (HV and MV GIE), as well as in RPC particle detectors (Koch and Franck 2015, Hosl et al. 2020, Chachereau et al. 2016, Preve et al. 2017). The improvement of existing applications relies on relevant and reliable data, which can be obtained from breakdown measurements. Here, we present the results from our measurements of dc breakdown in trans-1,3,3,3- tetrafluoropropene. Our measurements are done in a centimeter-sized plan-parallel electrode system (Sivoš et al. 2020), under swarm conditions at low currents (~ 1 μA) and low pressures (~ 0.05 – 3 Torr). In Figure 1, we present breakdown results for trans-1,3,3,3-Tetrafluoropropene (HFO1234ze(E), C3H2F4) in comparison with sulfur hexafluoride (SF6). Paschen curve of HFO1234ze(E) is recorded for electrode distance of 1 cm. The minimum breakdown voltage of 482 V occurs at pd = 0.25 Torrcm (p – pressure, d – electrode distance). The discharge ignites and operates stably at low-currents up to ~ 0.8 Torrcm, but above this value discharge ignites into periodic relaxation oscillations (Kuschel et al. 2011). The breakdown voltage values for HFO1234ze (E) are slightly lower than those for SF6 around the Paschen minimum and on the right-hand side of the Paschen curve.On the other hand, at lower pressures, the breakdown voltage of HFO1234ze(E) increases steeply and be ... - FULL TEXT available in PDF.
Impact of Coulomb correction on the nonadiabatic tunnel ionization in an elliptically polarized laser field
Authors: Petrović V.M. , Delibašić Marković H.S. , Petrović I.D.
Published: December 2024

Using a time-imaginary method rooted in the Landau-Dykhne model (Landau 1977) within the frame of the trajectory-based semiclassical approach, we developed an analytical model that investigates the impact of the Coulomb interaction between the atomic core and the escaping electron for a monochromatic elliptically polarized laser field on the tunnel ionization rate. We introduced an additional term in the imaginary part of the classical action due to the Coulomb interaction.This correction becomes substantially significant in the sub-barrier region, where the electron comes near the singular Coulomb core, influencing the complete tunneling dynamics. To accurately model these effects, we computed the electron trajectory considering the Coulomb forces and derived analytical expressions for both the initial and drift momenta (Petrović et al. 2023). Our results suggest that, in the whole considered ellipticity range, the Coulomb correction provides a significant, orders-in-magnitude, enhanced the total ionization rate without significantly altering its shape.Our results indicate that including the Coulomb correction not only modifies the energy distribution of the ionized electrons but also results in a narrower momentum distribution compared to models that omit this correction. These insights have significant implications for a broad spectrum of laser-matter interactions and could guide future research efforts in the field. - FULL TEXT available in PDF.
Bounds on graviton mass from astrometric data of S-stars
Authors: Jovanović P. , Borka Jovanović V. , Borka D.
Published: December 2024

Here we use a Yukawa-like correction of the Newtonian gravitational potential, proposed by C. Will (see Ref. Jovanović et al. 2024a) in order to obtain new bounds on graviton mass from the observed orbits of S-stars around Sgr A*. We assumed that the orbital precession of these stars is close to the prediction of General Relativity (see the results of GRAVITY Collaboration in 2020 and 2022) for Schwarzschild precession, but with a possible small discrepancy from it. By comparison of the observed orbits of bright stars (Gillessen et al. 2017) in the Galactic center with their simulated orbits in Yukawa-like gravitational potential, we estimated the constraints on the parameters of this modified theory of gravity. With this approach, we were able to constrain the parameter λ of the potential. Moreover, assuming that λ represents the graviton Compton wavelength, we also found the corresponding upper bound of graviton mass. The obtained results were then compared with our previous estimates (Jovanović et al. 2023, Jovanović et al. 2024b), as well as with the estimates of other authors. Also, obtained results are in a good agreement with the coresponding LIGO results.

El antifranquismo en la Cataluña autónoma (1980-2003)
Authors: Duch Plana Montserrat
Published: December 2024

El antifranquismo no se constituyó en núcleo de la narrativa de la transición y consolidación de la democracia en Cataluña y en España que se construyó sobre el discurso de la modernización y la no instrumentalización política del pasado. El trabajo de la memoria manipula los usos públicos de la historia en función de intereses del presente así restituye o sustituye hechos, personas y lugares de memoria. ¿Hasta qué punto la desmemoria del antifranquismo en la Catalunya autónoma es funcional en la reconstrucción de identidades sociales y comunitarias? El análisis se focaliza en las políticas de la memoria oficiales.
