Applicability of the Deed of Agreement for Unilateral Termination of the Build Operate Transfer (Bot) Cooperation Agreement After the Court's Decision
Authors: Anjilna Rostna Qitabi
Published: January 2024

The Government of Indonesia uses the Regional Revenue and Expenditure Budget to finance infrastructure development and regional development. To avoid high development costs, the government opens up opportunities for the private sector to invest in state assets (land) with the Build Operate Transfer system (hereinafter referred to as BOT). In the BOT model, the government permits the private sector to build and operate the project for a certain period. As an unnamed agreement, there has been no specific arrangement regarding cooperation with the BOT system. Therefore, the BOT agreement was born based on the freedom of contract as regulated in Article 1338 of the Civil Code. This agreement tends to cause legal problems such as unlawful acts. This research method is normative with secondary data sources using primary, secondary, and tertiary legal materials. In the event of unilateral termination of the BOT agreement, it still refers to Article 1266 of the Civil Code. If one of the parties has not fulfilled all the elements contained in Article 1266, the responsibility for unilateral termination is compensation. Keywords: Unilateral Termination; Build Operate Transfer, Enforcement of Deed of Agreement

Published: January 2024

Background. The family has a pattern of relationships or rules of behavior and is a social institution that has a system of norms and procedures for completing important tasks. The family is an important social institution in Indonesia, where the family has a set of norms and rules to accomplish important tasks in the family. Families play an important role in shaping a person's character and social behavior in society. The main task of the family is to pass on traditions, attitudes, behaviours and values by creating an environment conducive to positive interaction and socialization between the child and their environment. The Minangkabau community in Indonesia, originating from West Sumatra, has a matrilineal kinship system, which emphasizes childcare by the mother and guidance from the mother's brothers. In contrast, the father's role is to provide for the family. The Batak community has a patrilineal kinship system, where kinship relationships are based on the father's lineage. In Batak tradition, men have a higher status than women, and only men are allowed to make decisions in family discussions.

Methods. This study is quantitative in nature using descriptive methods. The population of this study was 600 Minangkabau families and 480 Batak families in Medan with a sample of 169 people, of which 86 people from the Minangkabau tribe and 83 people from the Batak tribe.

Published: January 2024

Mochi is a cake with a chewy and soft texture made from glutinous rice flour and contains peanuts. This sticky rice flour causes the color of the mochi to turn milky white. This can be corrected by adding natural dyes to make the appearance of mochi more attractive. Carrots can be used as natural dyes in making mochi, indirectly the mochi produced becomes healthier and more nutritious. This study aims to determine the physical characteristics of mochi with the addition of carrot paste and find out the right formulation in adding carrot paste to mochi that is liked by the panelists. This research method used an experimental method with a randomized block design (RBD) 1 factorial, namely the addition of carrot paste concentrations of 0%, 25%, 50%, 75%, and 100%. The results showed that the mochi produced had an overall appearance that was quite flour-coated and the shape was less uniform, pale orange in color, typical flour aroma, chewy, and sweet in taste. The best results most preferred by the panelists in this study were obtained through analysis of physical characteristics, namely the treatment of adding 25% carrot paste concentration with an overall appearance value of 4.00, color 3.87, aroma 3.80, elasticity 3.67, and taste 3 ,93.

Published: January 2024

Disclosure of financial report findings from Public Accountants is the most important aspect of financial reports. Disclosure of findings can provide an easy understanding of report content for users to make informed decisions. The research conducted is normative legal research. The results of the study state that Public Accountants are in a subordinate and minor position due to the lack of protection for the exercise of their profession given the high legal threat. Even if it is true that the intent of the formulation of Article 55 letter a of the Public Accountants Law is to protect the public interest from the possibility of falsification or fraud perpetrated by an Accountant, the public's interests have been adequately protected by the provisions of the Criminal Code (delict of counterfeiting or fraud), so therefore the provisions of Article 55 letter a The aquo law is an exaggerated and even fantastic provision. Thus Article 55 letter a of the a quo law creates uncertainty in the law and contradicts the principle of lex certa which is the basic principle in criminal law of the inclusion of criminal sanctions as determined by Articles 55 and Article 56 of the a quo law in the perspective of humanistic criminal law is imprecise and irrational. Keywords: public accountant, cancellation, Constitutional Court's decision

Published: January 2024

Child marriage is a controversial issue in many countries, including Indonesia, due to its negative impact on girls. Indonesian law regulates the minimum age for marriage, but there are still gaps in its implementation. This issue also relates to social, economic, and health impacts, such as reproductive health risks and limited access to education. This research aims to review the implementation of child marriage policies, policy orientations, and their impact on the understanding and implementation of maslahah mursalah values. This study uses normative legal research methods to examine the issue of child marriage based on the normative aspects present in applicable legislation. The results of the research indicate that the implementation of child marriage policies based on maslahah mursalah in Indonesia should be holistic, considering social, cultural, religious, and legal aspects. This policy should prioritize the common welfare and protection of children's rights, with an emphasis on education, legal protection, reproductive health, and reducing social stigma. The importance of collaboration between the government, NGOs, religious leaders, and the community in designing and implementing this policy is emphasized. Regular evaluations need to be conducted to ensure the effectiveness of the policy in achieving the goals of child protection and public welfare. Additionally, consideration should be given to the cultural and religious diversity in Indonesia while adhering to international commitments supporting the prohibition of child marriage.
Transmission, Crisis, and Identification in Ocean Vuong’s on Earth We’re Briefly Gorgeous: A Post-Memory Study
Authors: Agustin Nerry
Published: January 2024

Post-memory is a study of traumatic memory transmission from first-generation to post-generation. A transmission of traumatic memories often leads to complicated effects on the post-generation. This novel tells the story of a young boy called Little Dog, who lives with his grandmother Lan and his mother Rose, who are the Vietnam War survivors. As a post-generation of the Vietnam War survivor, Little Dog has to live in a complex reality because of the traumatic past of his family. This study aims to describe the transmission, form of crisis, and identification of traumatic memories constructed in Ocean Vuong’s On Earth We’re Briefly Gorgeous. It applies the theory proposed by Marianne Hirsch, known as post-memory. It is a qualitative study that uses a descriptive analysis method and exercises several stages, namely, the determination of data sources and data, data collection, and data analysis. The results show that the form of traumatic memory transmission occurring in this novel is familial transmission. Little Dog experiences this transmission because of his grandmother, Lan, and his mother, Rose, daily behavior. The transmission of traumatic memory has caused a crisis within Little Dog that then prompts him to identify the transmitted traumatic memory. The form of memory identification occurring within Little Dog was a combination of idiopathic and Heteropathic. Writing has helped Little Dog to understand, articulate, narrate, and finally accept his familial traumatic memory as a part of his life.

Interpretation of Entropy by Complex Fluid Dynamics
Authors: Fujino Seiji
Published: January 2024

We consider that the relationship between entropy in statistical mechanics, which is the Boltzmann principle, and the complex velocity potential in complex fluid dynamics. We define the generalized complex entropy which expanded entropy from real space to complex space. We show that the complex entropy can be expressed by the composition of sources, sinks and laminar flows of the complex velocity potential. Therefore, the complex entropy is considered a special case of the complex fluid dynamics,that is, the complex velocity potential. In other words, we show that the complex entropy is expressed by the complex velocity potential. Moreover, we show that a complex number is expressed by the complex entropy. Thus, we show that the complex velocity potential is expressed by the complex entropy. Namely, we will expand entropy to complex space and see that the complex entropy is expressed by the complex velocity potential. Furthermore, we examine the possibility that it is an expansion of Boltzmann's principle and Planck distribution.

Published: January 2024

The aim of the study was to examine the influence of different irrigation protocols on the shear bond strength (SBS) of self-adhesive resin composite cement (SARC) to primed radicular dentin. Radicular dentin slabs (N=58) were sectioned from extracted intact third molars, embedded in acrylate, polished, and randomly assigned to five experimental groups (N=8-12) and one control group, CG (N=8). Irrigation solutions used were sodium hypochlorite (H), ethylene-diamine-tetra acetic acid (EDTA), etidronic acid with hypochlorite (HEDP), saline solution (SS), and chlorhexi-dine (CHX). Each experimental group underwent different irrigation protocol for two minutes: 1) H/EDTA/H, 2) HEDP, 3) H/EDTA/CHX, 4)H/EDTA/SS, and 5) HEDP/SS. The CG samples were not treated with any irrigation solution. After drying, adhesive enhancing primer (AEP) and du-al-curing SARC were applied to the radicular dentin using molds corresponding to the Ultra Tester. Specimens were stored at 37°C in distilled water and fractured in shear mode after 10 days. The results were analyzed using the ANOVA statistical test and Post-hoc Games-Howell test, α=0.05. CG exhibited the highest SBS. Except for HEDP and HEDP/SS, all experimental groups showed significantly lower SBS compared to the control group (p< 0.05). HEDP seems to be ad-equate solution for root canal cleaning before dentin priming and fiber post cementation with self-adhesive resin cement. Cleaning protocols with H, EDTA and CHX cause a significant de-crease in bond strength.
Social Media Monitoring as a Strategy for Online Reputation Management in Zimbabwe’s Life Assurance Industry
Authors: MANDINA SIPHIWE , Matsika Nicholas
Published: January 2024

This research investigates the impact of social media monitoring on Online Reputation Management (ORM) within Zimbabwe’s life assurance industry. Employing a mixed-methods approach, data was collected through questionnaires from 464 participants, yielding a response rate of 92.8%. Ethical considerations were meticulously addressed, with informed consent and confidentiality safeguards. Data analysis involved organizational and statistical techniques, including Structural Equation Modeling (SEM) for theoretical exploration. Descriptive statistics unveiled demographic insights and patterns in social media platform usage. Internal consistency assessments, Exploratory Factor Analysis (EFA), and Principal Component Analysis (PCA) informed the refinement of research instruments. The SEM analysis established significant relationships and moderation effects, providing empirical support for several hypotheses. Findings indicate that employees’ attitudes toward social media monitoring positively influence ORM, while perceived behavioural control exhibits a non-significant impact. Intriguingly, management commitment, though positively related to ORM, moderates the relationship with a negative effect. The study contributes to the understanding of ORM determinants, emphasizing the need for nuanced strategies considering both individual and organizational factors. The recommendations underscore the importance of management commitment and employee training for effective social media utilization. Future research avenues include exploring training interventions, delving into the dynamics of perceived behavioural control, and investigating emerging social media platforms’ impact on ORM.
Numerical Simulation Approaches for Vertical-Axis Wind Turbines: Investigating Airfoil Design and Predictive Techniques
Authors: Adesiyan Ayomide , Akinnawo Olumide
Published: January 2024

The application of numerical simulation methods for studying vertical-axis wind turbines offers significant advantages over conventional horizontal-axis wind turbines regarding wind energy utilisation, start-up wind speed, and environmental impact. This paper aims to investigate and establish the aerodynamic design performance of asymmetrical (NACA 4412) airfoils used in the application of vertical-axis wind turbines. The computational fluid dynamics (CFD) simulation uses Ansys software based on the Reynolds Averaged Navier-Stokes (RANS) equations. The aerodynamic parameters (pressure and velocity) are evaluated and compared within a range of angles of attack (AoA) 5-12 degrees at a fixed Reynolds number, as is a usual condition for wind turbine application. The lift coefficient (Cl), drag coefficient (Cd), and Cl/Cd ratio are obtained within the range AoA for the asymmetrical airfoils, and the performances have been predicted using the potential flow panel and CFD methods. This study suggests that while Xfoil may not be as precise as computational fluid dynamics (CFD), its predicted lift and drag coefficients generally align with experimental results. These help us to understand the best air-foil selection in a wind turbine application and predict its optimum AoA at which it performs at its best.
Characterization of Fibers Prepared by Centrifugal Spinning from Biotechnologically Derived Chicken Gelatin
Authors: Martinek Jakub , Mokrejš Pavel , Gál Robert , Hřibová Martina , Pokorný Pavel , Janáčová Dagmar
Published: January 2024

Gelatin fibers have a specific surface and high porosity, which is why their use in medicine and the food industry is being researched. This article explores the potential of centrifugal spinning to produce gelatin fibers. Gelatin for fiber preparation is obtained from a non-traditional source of collagen (chicken by-products) using a unique enzymatic process. The fiber quality is compared with those prepared from traditional collagen tissues (porcine, bovine). The results show that fibers crosslinked with glutaraldehyde vapor preserve their structure even in contact with water. Using a cross-linker controls swelling ability and solubility while maintaining the fiber structure. On the contrary, uncross-linked gelatin fibers are water soluble due to a high surface-to-volume ratio, facilitating water penetration and dissolution. Scanning electron microscopy (SEM) provided a clearer picture of the morphology of gelatin fibers obtained by centrifugal spinning. Differences in the amount of bonding depending on the raw material used and the presence of cross-linker were analyzed using Fourier transform infrared spectroscopy (FTIR). The overall results showed that chicken gelatin is a suitable alternative to gelatins from traditional sources.
The Intermittency of Turbulence in Magneto-Hydodynamical Simulations and in the Cosmos
Authors: Lesaffre Pierre , Falgarone Edith , Hily-Blant Pierre
Published: January 2024

Turbulent dissipation is a central issue in the star and galaxy formation process. Its fundamental property of space-time intermittency, well characterised in incompressible laboratory experiments, remains elusive in cosmic turbulence. Progress requires the combination of state-of-the-art modelling, numerical simulations and observations. The power of such a combination is illustrated here where the statistical method intended to locate extrema of velocity shears in a turbulent field is applied to numerical simulations of compressible magneto-hydrodynamical (MHD) turbulence dedicated to dissipation scales and to a nearby turbulent diffuse molecular cloud. We demonstrate that short-spacing increments of observables can detect strongly dissipative structures. In our simulations, we compute structure functions of various synthetic observables and show that they verify Extended Self-Similarity. This allows to compute their intermittency exponents and we show how they could help constraining some properties of the underlying three-dimensional turbulence. In observations of a turbulent cloud close to the Sun in our Galaxy, a remarkable coherent structure of velocity shear extremum is disclosed . At the location of the largest velocity shear, this coherent structure is found to foster 10 × more carbon monoxide molecules than standard diffuse molecular gas, an enrichment supported by models of non-equilibrium warm chemistry triggered by turbulent dissipation. The power of the combination between modelling and observations is also illustrated by observations of the CH+ cation that provide unique quantitative informations on the kinetic energy trail in the massive, multi-phase and turbulent circum-galactic medium of a galaxy group at redshift z = 2.8.

Although crop conversion from annual to perennial crops has been considered as one path towards climate-smart and resource-efficient agriculture, the effects of this conversion on soil multifunctionality and biomass yields remain unclear. Here, we investigated the effects of one annual and three perennial crops (a grass (Lolium perenne), a legume (Medicago sativa), and their mixture) on soil multifunctionality and biomass yield on the Yellow River floodplain. Soil multifunctionality was assessed by the capacity of water regulation and the multifunctionality of carbon (C), nitrogen (N), and phosphorus (P) cycles. Results showed that perennial crops enhanced soil multifunctionality by 207% for L. perenne, 311% for M. sativa, and 438% for L. perenne + M. sativa, compared with annual winter wheat (Triticum aestivum). The effect of perennial crops on soil multifunctionality increased with infiltration rate, dissolved organic C, microbial biomass C, and extracellular enzymatic activities for both C and N acquisition. However, we observed that perennial crops had lower biomass yield than annual crop. Therefore, the transition of agricultural landscapes to perennials needs to take into account the balance between environmental protection and food security, as well as environmental heterogeneity, to promote sustainable agricultural development.

Graphene quantum dots (GQDs) possess the photosensitive absorption for photoelectrochemical hydrogen evolution owing to special band structures. Whereas they usually confront with photo-corrosion or undesired charge recombination during photoelectrochemical reactions. Hence, we establish the heterojunction between GQDs and MoSe2 sheets via hydrothermal process for improved stability and performance. Photoanodic water splitting with hydrogen evolution boosted by heteroatom doped N,S-GQDs/MoSe2 heterojunction has been attained due to the abundant active sites, promoted charge separation and transfer kinetics with reduced energy barriers. Diphasic 1T and 2H MoSe2 sheets hybridized quantum dots contribute to the Schottky heterojunction, which can play a key role in expedited carrier transport to inhibit accumulative photo-corrosion and increase photocurrent. Heteroatom dopants lead to favored energy band matching, bandgap narrowing, stronger light absorption and high photocurrent density. The external quantum efficiency of doped heterojunction has been elevated twofold over that of the non-doped pristine heterojunction. Modification of graphene quantum dots and MoSe2 heterojunction demonstrate a viable and adaptable platform toward photoelectrochemical hydrogen evolution processes.

.Background: Negative outcomes associated with medications (NOM) and drug-related problems (DRP) significantly impact individuals with kidney replacement therapy (KRT) given the complexities of managing kidney disease and associated comorbidities. The present study aims to assess the frequency of NOMs/DRPs among KRT patients and identify contributing factors. Methods: A cross-sectional study was conducted at the Virgen de las Nieves University Hospital (Granada, Spain), involving 117 outpatient adults with KRT. Data were collected from February 2021 to July 2023 using electronic records, semi-structured interviews (Dáder Method), and discussions with nephrology specialists. NOMs/DRPs were identified following treatment guidelines. Binary logistic regression determined associated factors (p-value < 0.05). Results: Across 117 patients, 2,436 NOMs and 3,303 DRPs were identified, averaging 20.82 NOMs and 28.23 DRPs per patient. Prevalent NOMs included untreated conditions (58.95%), quantitative ineffectiveness (35.43%), and non-quantitative safety problems (5.13%). Dominant DRPs were undertreated conditions (37.63%), wrong dose/posology/length (33.00%), risk of adverse drug reactions (ADR) (16.14%), and non-adherence (6.87%). Patients with ADR, undertreated condi-tions, and anemia were associated with quantitative ineffectiveness. Risk of ADR and vitamin D deficiency/insufficiency correlated with non-quantitative safety problems. Conclusions: KRT pa-tients exhibited a substantial prevalence of NOMs/DRPs. Further research is needed to deepen our understanding of these complexities for improved patient care.

Nowadays, it is highly desired to develop highly active and humidity resistive ozone decomposition catalyst to eliminate the ozone contaminant, one of the primary pollutants in air. In this work, a series of Cu2S hollow structured materials are rapidly synthesized using different structured Cu2O templates. The Cu2S from porous Cu2O shows the highest ozone catalytic decomposition efficiency of >95% to 400 ppm ozone with a weight hourly space velocity of 480,000 cm3g-1h-1 in dry air. Importantly, the conversion still keeps >85% in a high relative humidity of 90%. The mechanism is explored by diffusive reflectance infrared spectroscopy which shows the decomposition intermediate of O22-, and the X-ray photoelectron spectroscopy reveals the dual active site of both Cu and S. All these results show the effective decomposition of ozone by Cu2S especially in harsh environments, promising for active ozone elimination.

The pollution caused by nitrogen dioxide is a major environmental problem in China. This study introduces a new type of atmospheric trace gas remote-sensing instrument, an airborne fiber imaging spectrometer. This spectrometer has a spectral range of 300–410 nm and works in push-broom mode with a 30° field of view on a flight path. Flight experiments were conducted on December 30, 2022 and January 5, 2023, covering heavily polluted areas of east of Beijing and Tangshan. This equipment obtained the density distribution of NO2 over the flight area. The results showed that pollution was mainly concentrated in the Caofeidian area and at the power station in the north, and the main source of pollution was anthropogenic. Satellite and airborne data near the pollution points were compared, and the two datasets showed a positive correlation with a correlation coefficient of 0.78 and 0.7, on the two days, respectively. This study demonstrates the capability of an airborne fiber imaging spectrometer for NO2 regional emission remote sensing and identifying the pollution points.
Evidence of Elliptical Intrusions and Sr, Hf, Pb, O Isotopes of the Khanbogd Alkali Granite Pluton: Constraction of Under-plating Magma Associated with the Duplex Thrust

The studied Khanbogd pluton of peralkaline granite is located in southern Mongolia and occupies an area of ~1000 sq. km. Previously, two ring-shaped bodies were constructed in a flattened shape pluton. However, this shape was not used for the genesis of this pluton. A recent study of Landsat image showed a several elliptical intrusions in two bodies. Chemistry interpretation shows that each intrusion differs in ASI, CIPW norms, 87Sr/86Sri and δ18O isotopes. Elliptical intrusions, uplifted country rocks between them, and roof pendants suggest magma penetration along fractured country rocks. Furthermore, two adjacent intrusive bodies and undeformed host rocks at the front part of the pluton are consistent with underplating magmatic factors during duplex-type thrusting. This magma event is also supported by low of Sr, Ba, Eu and high of Th, U, Pb anomalies and a few amount of garnet crystals in the granites, implying vapor absent melt crystallization associated with underplating. Multiple melt sources, as well as from mantle and recycled sea floor rocks, are identified by ratio of 87Sr /86Sri and δ18O values. The low isotope values, the thrust nature and 295–286 Ma ages of the alkali granites, indicate an underplate magma evidenced during Permian rifting.

Drones are being used more and more frequently and in various ways to attack people and critical infrastructures, which increases their level of danger and makes early detection and risk assessment even more difficult. There is no ultimate drone sensor. Rather, drones can only be effectively detected, if suitable sensor technologies are integrated within a system. Among the best suited sensorics for this purpose are radar and optical sensors, because the advantage of the radar, given by the long detection range, can be well combined with the additional visual-based information gained from a camera in the mid- and short-range, where usually the radar fails detecting micro drones. In this paper, a modular drone detection and assistance system MODEAS is presented, which can be used to automatically detect and track drones within a range up to some kilometers on the sky, but also in complex urban environments, where buildings and vegetation offer a perfect background for camouflage. The system provides an early detection of flying objects as potential drones, when those are not at all or only as small dots visible for the human eye. Main strengths of the system are the robust AI detection to differentiate such an object against clutter (birds, clouds) and its further classification by model and payload recognition, the latter aspect being considered as an indication of dangerousness. Moreover, once a drone is detected, the system follows it automatically, precisely and smoothly with a high-resolution pan-tilt-camera, measuring the distance to the sensor station with a laser rangefinder, compute the geocoordinates and visualize them live on a map. To improve the precision of the detection, a multisensorial fusion of all sensor detections is performed. Furthermore, alarms may be generated when a drone enters a restricted area.
