Published: September 2024

Sexual and gender-based violence is common all around us, even in college settings. From 2015 to 2021, there were 35 reports of sexual violence in college entering the Women's Chamber. The high rate of sexual abuse in college education, impacted on the publication of Permendikbud No. 30 Year 2021 on Prevention and Suppression of Sexual Violence in College. One of the most serious online media outlets reporting on cases of sexual violence in colleges is Tirto.id. Through Pan & Kosicki's analysis of the news, Tirto.id's position on college sexual assault groups tends to be biased on victims because Tirto is also advocating victims. Tirto.id doesn't dramatize by not giving a flattering opinion, but by providing chronology and facts on the victim's side. Tirto.id also continues to advance the presumption of innocence of the perpetrator because of his case which is still under investigation.

In coastal basins separated from the White Sea due to post-glacial uplift, the spectrum of light at the boundary of the photic zone gradually shifts towards long waves: from predominantly green (in marine area and in bucket bays) to green-orange-red in lagoons, then to yellow-orange-red in meromictic lakes with fresh mixolimnion and orange-red in fresh lakes. This is due to increase of concentration of humic substances (CDOM, «yellow substance»). They attenuate short-wavelength light and reduce the photic zone. The light spectra are consistent with the color of photosynthetic microorganisms that dominate in the chemocline zone. Under green light, microorganisms with red pigments in the photosynthetic antennae receive an advantage, and under orange-red light, cells with a green color are advantageous. The relationship between the concentration of humic substances in surface waters and the pigment composition of microorganisms opens up the opportunity of assessing the stage of isolation and salinity of the mixolimnion, as well as influx of humic waters from the catchment area based on the remains of pigments in columns of anaerobic sediments.
Stereoselective mechanochemical synthesis of thiomalonate Michael adducts via iminium catalysis by chiral primary amines
Authors: Błauciak Michał , Andrzejczyk Dominika , Dziuk Błażej , Kowalczyk Rafał
Published: September 2024

The study presents a novel approach utilizing iminium salt activation and mild enolization of thioesters, offering an efficient and rapid synthesis of Michael adducts with promising stereoselectivity and marking a significant advancement in mechanocatalysis. The stereoselective addition of bisthiomalonates 1–4 to cyclic enones and 4-chlorobenzylideneacetone proceeds stereoselectively under iminium activation conditions secured by chiral primary amines, in contrast to oxo-esters as observed in dibenzyl malonate addition. Mild enolization of thioesters allows for the generation of Michael adducts with good yields and stereoselectivities. Reactions in a ball mill afford product formation with similar efficacy to solution-phase reactions but with slightly reduced enantioselectivity, yet they yield products in just one hour compared to 24 or even 168 hours in solution-based reactions. It is noteworthy that this represents one of the early reports on the application of iminium catalysis using first-generation chiral amines under mechanochemical conditions, along with the utilization of easily enolizable thioesters as nucleophiles in this transformation.

Published: September 2024

This study explores the dynamics of atmospheric pollutants released from various sources, including vehicular traffic, small and large-scale production, building industries, and various other human activities, to lessen the threat posed by global warming. These pollutants are also responsible for causing severe respiratory ailments and numerous fatalities among human populations. The presence of various pollutants emitting sources has led to a rise in the cumulative concentration of pollutants in the atmosphere that pose a threat both to the environment and human health. Therefore, it is very important to study the mitigation of such pollutants by making people aware of their harmful effects. Media awareness campaigns can have a significant impact on the mitigation of pollutants in the atmosphere causing global warming. Given this, in the present study, the role of media awareness campaigns in the abatement of pollutants is ex-plored by developing and analyzing a nonlinear mathematical model. The stability theory of ordinary differential equations is used to analyze the mathematical model. To investigate the feasibility of the model system, local and global stability conditions are established. The model analysis demonstrates that media awareness programs have a significant impact on reducing air pollutants, which in turn reduces global warming.

Performance Measurement in the Context of Public Administrations: What Application for Niger Customs?
Authors: BOUGA Boukari DAN
Published: September 2024

Performance measurement has been a central concern for managers for many years. Admittedly, it has mobilized more literature in the private sector, where production is commercial, but it was not long before it made its mark in the public sector either, according to the work of Hood (1995). It is reasonable to believe that the determining circumstances of this development include the birth of citizen movements and the advent of the Awards of Excellence. Thus, indicators and tools are developed to measure the performance of all kinds of organizations. This paper raises the issue of measuring the performance of public administrations. Would it not be unfair to apply the concept of comprehensive performance of the company (Baret 2006) to a public administration? Wouldn't it be better to look for the determinants of its performance in the formal statement of its missions in relation to the individual performance of its staff?

The Distribution of Planet Radius in Kepler Multiplanet Systems Depends on Gap Complexity
Authors: Rice David R. , Steffen Jason H. , Vazan Allona
Published: September 2024

The distribution of small planet radius (<4 R
⊕) is an indicator of the underlying processes governing planet formation and evolution. We investigate the correlation between the radius distribution of exoplanets in Kepler multiplanet systems and the system-level complexity in orbital period spacing. Utilizing a sample of 234 planetary systems with three or more candidate planets orbiting FGK main-sequence stars, we measure the gap complexity (C) to characterize the regularity of planetary spacing and compare it with other measures of period spacing and spacing uniformity. We find that systems with higher gap complexity exhibit a distinct radius distribution compared to systems with lower gap complexity. Specifically, we find that the radius valley, which separates super-Earths and sub-Neptunes, is more pronounced in systems with lower gap complexity (C < 0.165). Planets in high-complexity systems (C > 0.35) exhibit a lower frequency of sub-Earths (2.5 times less) and sub-Neptunes (1.3 times less) and a higher frequency of super-Earths (1.4 times more) than planets in low-complexity systems. This may suggest that planetary systems with more irregular spacings are more likely to undergo dynamic interactions that influence planet scattering, composition, and atmospheric retention. The gap complexity metric proves to be a valuable tool in linking the orbital configurations of planets to their physical characteristics.
Linear programming-based stochastic stabilization of hidden semi-Markov jump positive systems
Authors: Jia Xuan , Zhang Junfeng , Raïssi Tarek
Published: September 2024

This paper focuses on the stochastic stabilization of hidden semi-Markov jump nonlinear positive systems. First, a notion of stochastic stability is introduced for this class of systems. A criterion is addressed to ensure the stochastic stability using a stochastic copositive Lyapunov function. Then, an observed mode is proposed to estimate the emitted value of the hidden semi-Markov process and the mode-dependent controller is designed using an improved matrix decomposition approach. Some auxiliary variables are added to decouple the coupling terms in hidden semi-Markov jump nonlinear positive systems into a tractable condition. All conditions are described in terms of linear programming. Moreover, the proposed design is developed for systems with partially known emission probabilities. Two examples are provided to show the validity of the obtained results.

Published: September 2024

The traditional approach to logistics path planning is hindered by lengthy procedures. In this study, we explore the multi-objective optimization of logistics management, considering the conventional path and time efficiency indices alongside shelf safety and stability as additional objective functions. Based on particle swarm optimization (PSO), we optimize objective functions for internal path planning, scheduling timeliness, and shelf safety and stability. We then determine optimal routes under varying order demands using PSO and ultimately optimize the final path using dynamic programming and spline function restrictions to meet actual demand. Empirical results indicate that the proposed solution method outperforms other calculation methods, such as genetic algorithm (GA) and simulated annealing (SA), demonstrating over 10% improvement in time and total distance consumption. Further practical application tests demonstrate that the model in this study has a beneficial impact on all five distinct types of orders through efficient deployment optimization.

Published: September 2024

The nanosized samarium doped tin oxide in varying concentration (0%, 0.5%, 1%, 3%, 5%) was successfully synthesized using the wet chemical precipitation approach. X-ray Diffraction (XRD) analysis was done to monitor the effect of the dopant concentration to the host lattice as broadening and narrowing of the formed peaks are seen. Average crystallite sizes of the produced sample are ranging from 9-28 nm, confirming it to be nanoscale. Identified peaks with Miller indices of ((110), (101), (200), (111), (211), (220), and (002) signifies a tetragonal rutile structure of the synthesized samples. Scanning Electron Microscopy (SEM) shows the difference in morphology for the powdered samples as per different samarium loading as well as the shape, which is granular. Energy Dispersive X-ray spectroscopy (EDX) affirms the successful integration of the samarium dopant to the lattice structure of the SnO2.
Finite Element Simulation of Split Hopkinson Pressure Bar (SHPB) Test to Predict the Dynamic Compressive Behavior of Glass Fiber Reinforced Polymer (GFRP) Composite
Authors: Yusuf Nojeem A. , Khair-Eldeen Wael , Tsuchiya Toshiyuki , Hassan Mohsen A.
Published: September 2024

Glass fiber reinforced polymers (GFRPs) are becoming increasingly important in aerospace, construction, and automotive industries due to their potential for weight reduction, high strength, and excellent fatigue resistance. The failure mechanisms of GFRPs are influenced by factors such as strain-rate, frequency, stress state, and temperature. However, existing constitutive models have predominantly focused on characterizing the material's behavior under quasi-static conditions, potentially limiting their accuracy when applied to situations involving higher strain rates. This study employs explicit dynamics finite element analysis to examine the impact of high strain rates on the dynamic compressive behavior of glass fiber reinforced polymers (GFRPs) in an ABAQUS CAE environment using the Split Hopkinson Pressure Bar (SHPB) experimental setup. The mechanical response of the [0/90]16 GFRP laminate system is characterized using the orthotropic elasticity material model and Hashin Damage Criteria is used to model the damage properties. Based on stability of total model energy, mesh convergence test was conducted across various mesh sizes to obtain the optimal mesh size for validating the developed FE-model. The simulation results highlight a notable increase in the compressive stress of the GFRP, rising from 200 MPa to 663 MPa as the strain rate increases from 596 s-1 to 1743 s-1. These results have shown the strain rate sensitivity of GFRPs and offer valuable insights for the prospective design and application of GFRP composites.

Diabetes Remission – The New Therapeutic Goal in Management of Type 2 Diabetes Mellitus
Authors: De Abrew T. , Subasinghe C. J.
Published: September 2024

Type 2 Diabetes mellitus is a complex progressive metabolic disease with rising global prevalence. It was believed to be an inexorably progressive disease, despite optimum gluco - centric management with escalating pharmacotherapy and lifestyle modification. In recent years, the concept of diabetes remission has gained enormous public and professional interest. Type 2 diabetes mellitus is strongly linked to obesity and there is clinical evidence that substantial weight loss through weight loss interventions could make diabetes remission a reality. Diabetes remission can be achieved through metabolic bariatric surgery and intensive lifestyle interventions targeting weight loss. Novel pharmacotherapy, SGLT2 inhibitors and GLP1-RA have an important role in achieving weight loss in addition to glucose lowering effect. Even though diabetes remission is achievable in selected groups of individuals, maintenance of remission is the biggest challenge. It is the right time to embrace diabetes remission as a main therapeutic goal in diabetes management in order to face the increasing global burden.
High-Fidelity Simulations of Rotors in a Compact Configuration
Authors: Miesner Sebastian , Keßler Manuel , Krämer Ewald
Published: September 2024

High-fidelity computational fluid dynamics (CFD) simulations of seven rotors in compact configuration at three different flight scenarios are performed. The cases are hover as well as 50 and 100 km/h forward flights. For comparison, each rotor is simulated as an isolated rotor with
the same RPM and pitch angle as in the configuration. Additionally, a bigger isolated rotor with the same diameter as the complete configuration is simulated. For the configuration as well as the bigger rotor a flight mechanics trim is performed using the flight mechanics tool VFAST. The CFD
simulations are performed with FLOWer. In hover, only the center rotor showed a significant figure of meritdrop of 16% compared to the isolated rotor. The thrust of the outer rotors is increased at the tip areas facing outwards, while the tip areas towards the center and the tip areas of the
center rotor showed reduced thrust compared to the isolated rotor. The wake contraction at the outer rotors is increased compared to the bigger rotor. For the 50 km/h forward flight, the efficiency of the front rotors is increased (10‐17%) and the rear ones decreased (11‐16%).
In this case, the wake is directly convected from the front rotors into the rear rotor planes and strong vortex interactions occur. For the 100 km/h case, the efficiency of the front rotors increases by 3‐11%, while it decreases by 5‐9% for the rear rotors. Due to the
higher pitch, the wake of the rotors flows away from the rotor plane and the rotor‐rotor interactions are reduced.

Introduzione: l'arresto cardiaco è una delle principali cause di morte. Atteggiamenti e pratiche degli operatori sanitari influenzano la sopravvivenza dopo un arresto cardiaco, soprattutto nei reparti intensivi. Il mantenimento di abilità e attitudini dopo l'addestramento alla rianimazione cardiopolmonare richiede un refresh sistematico con metodologia appropriata. L’obiettivo è valutare la percezione di efficacia degli operatori sanitari nella conduzione della rianimazione cardiopolmonare su adulti al fine di ottimizzare la progettazione di iniziative formative sul tema orientate ad approfondire gli aspetti critici.
Materiali e Metodi: studio trasversale su 655 professionisti sanitari che tra il 2020 e fine 2022 hanno partecipato al corso di formazione aziendale BLS-d. È stato somministrato un questionario ad hoc costituito da 65 variabili.
Risultati: hanno risposto 132 professionisti. Le aree critiche sono risultate: ruolo esclusivo del personale sanitario nella rianimazione cardiopolmonare, presenza della famiglia, fiducia nella pratica, aspetti etico-legali, lavoro in team.
Conclusioni: il corso BLS-d, standardizzato e focalizzato sull’aspetto tecnico, non affronta aspetti paralleli quali lavoro in equipe, aspetti etico-legali, pregiudizi, e problemi di fiducia in sé che necessitano di esperienze alternative. La prosecuzione di questo lavoro prevede il coinvolgimento di tutto il team di istruttori BLS-d aziendali al fine di individuare strategie alternative di integrazione dei contenuti.

Mechanical and agricultural process for controlling Eobania vermiculata (Gastropoda: Helicidae) in citrus orchards in Qalubia Governorate, Egypt
Authors: Khidr Eman Kamel
Published: September 2024

The effect of some mechanical and agricultural control methods has been evaluated against Eobania vermiculata (Müller) (Gastropoda: Helicidae), snail under field conditions. Outcomes revealed that hand collection of some points at mid-autumn to early wintry weather gave a reduction percentage of 60.43% in the long run in four weeks with a general mean of 73.99%. Therefore, the number of snails laying eggs decreased. Also, a ploughing process in February and March duration gave reduction percentages of 57.8% at the end of the four weeks, while at the same time general mean was 69.29%. As a result, the number of snails and hatchable eggs decreased while hand collection during mid-April and May and gave a reduction percentage of 23.27% in the long run of the four weeks whereas the general mean was 44.507%. The impact of some trap types for land snails such as wet Sacking, Plastic Sheets, and molasses+ wheat was used as snail-appealing material that will compare their suitability for attracting snails in traps. It's far apparent that the very best recorded numbers of snails have been sheltered under portions of wetted Sacking+ molasses + wheat which gave (108), Plastic sheets+ molasses + wheat (17) while recorded (40) and (10) for sacking and plastic sheets (Without any attractive), respectively after 72 hrs. of remedy so it can be recommended that ploughing, wetted Sacking best (Attractive ) and hand collection were the best processes for E. vermiculata snail population reduction in citrus orchards.

User Satisfaction with Technology-Enhanced Health Insurance among Community-Based Health Insurance Users: A Survey at one Selected Referral Hospital, Rwanda
Authors: Ferdinand  Maniriho Maombi  , Erigene Rutayisire
Published: September 2024

BackgroundExpanding health insurance coverage is crucial for improving access to healthcare services in Africa. While Rwanda has successfully implemented a community-based health insurance scheme (Mutuelle de Santé), the transition from traditional paper-based systems to Technology-based platforms presents a new challenge. Understanding user satisfaction with these new platforms is critical for their long-term success. ObjectiveThis study seeks to investigate the satisfaction level of community health insurance users attending the Outpatient Department at One selected Referral Hospital in Rwanda. MethodsThe mixed-methods study used an explanatory sequential design among 384 Community Based Health Insurance (CBHI) users. A structured questionnaire used for data collection; Analysis was done using Statistical Package for Social Sciences Version 21. ResultsThe majority of participants (81.3%) expressed satisfaction. Young participants aged <20 years (AOR:1.96, 95% CI:1.037-2.718, p=0.003) Young participants are very satisfied. Limited medication availability and internet reliance hindered user experience. Healthcare providers faced increased workload from managing patient files and the CBHI system. Improved payment processes and patient verification streamlined billing, saving time and reducing errors.ConclusionThe findings indicate a generally positive satisfaction and factors such as age, education, marital status, occupation, health insurance, and presence of under 5 children were found to be associated with satisfaction levels.

Purpose: To investigate the efficacy and safety of the traditional Chinese herbal formula (Tian-Teng Decoction) for the treatment of patients with hypertensive emergency.
Methods: 120 patients with hypertensive emergency who were treated in Hebei Provincial Hospital of Traditional Chinese Medicine between July 2021 and December 2022 were equally and randomly divided into study and control groups. Patients in the study group received orally Tian-Teng decoction (300 mL divided into two portions administered morning and evening for 2 weeks), while control group received only conventional treatment (sublingual captopril at 12.5 mg twice daily for 2 weeks). Symptoms improvement, changes in blood pressure, onset time, laboratory indicators, clinical manifestations, and adverse reactions were recorded.
Results: The study group exhibited significant decrease in blood pressure 30 min after medication (p < 0.05). Systolic and diastolic blood pressures were significantly lower in the study group compared to control group at 1, 2, and 3 h after medication. Nitric oxide (NO) was significantly higher, while angiotensin II (Ang Ⅱ), insulin-like growth factor-1 (IGF-1), angiotensin-converting enzyme (ACE), traditional Chinese medicine syndrome scores, and the incidence of adverse reactions were significantly lower in study group compared to control group (p < 0.05).
Conclusion: Tian-Teng Decoction demonstrates good efficacy and safety in the treatment of hypertensive emergency. Future studies that incorporate a larger sample size and prolonged observation period to validate the findings of this study are recommended.
Investigation of the bioactive constituents and some pharmacological activities of the ethanol extracts of Acanthospermum hispidum and Moringa oleifera
Authors: Ojo Femi , Özgör Erkay
Published: September 2024

Purpose: To determine the bioactive compounds in Moringa oleifera (MO) and Acanthospermum hispidum (AH) with antioxidant, anticancer, antifungal and antibacterial potentials.
Methods: Fresh leaves of these plants were collected from Akinmoorin and Awe, Oyo State, Nigeria. Particle-induced x-ray emission (PIXE) technique was performed using a 2.5MeV proton beam (a non-destructive elemental analysis). Phytochemicals were qualitatively analyzed using High-performance liquid chromatography (HPLC), gas chromatographic-mass spectrophotometer (GC-MS) and standard procedures. Disc diffusion method was used to determine the minimum inhibitory concentration (MIC) for fungi and bacteria. Antioxidant properties were carried out by DPPH radical scavenging activity. Cancer cells (MDAMB 231 and HTC 15) were cultivated in the presence of the extracts at body temperature with 5 % CO2 and 95 % air in 100 % relative humidity. Thereafter, adherent cells were seeded and treated with increasing concentrations of the plant extracts for 48 – 72 h.
Results: Phytochemical analysis showed that both plants contain alkaloids, flavonoids, anthraquinones, steroids and terpenoids, saponins, tannins, phenols and glycosides. The MIC for MO on fungi was 21.0 and 12.0 mg/mL for AH. Furthermore, MO MIC for bacteria was 25.25 mg/mL and 9.75 mg/mL for AH. Antioxidant properties revealed MO having 80.02 % and AH, 76 % at 32.00 µL. The ethanolic extracts showed a 50 % reduction in cancer cell viability at 24.5 μg/mL for MO and 16.0 μg/mL for AH, respectively, on MDAMB 231 and HTC 15 cells.
Conclusion: Moringa oleifera (MO) and Acanthospermum hispidum (AH) extracts exhibit significant antioxidant, antitumor, antifungal and antibacterial activities. Further studies will require that the active constituents be isolated and formulated into suitable dosage forms.

Purpose: To investigate the therapeutic effect of budesonide nasal irrigation and saline irrigation in patients undergoing surgery for  chronic rhinosinusitis (CRS).
Methods: One hundred patients scheduled for functional endoscopic sinus surgery (FESS) in Shanghai Ninth People’s Hospital, Shanghai  Jiaotong University School of Medicine, China were enrolled. The patients were divided into study and control groups comprising 50 cases  each. The study group received postoperative budesonide irrigation while control group received normal saline irrigation after surgery. Post-operative symptoms, signs, and adverse reactions of the patients were compared.
Results: Five weeks post-operation, the visual analogue scale (VAS) scores of nasal congestion, nasal discharge, nasal itching, sneezing,  nasal pain, and the score of nasal endoscopy one week and 4- weeks after operation were significantly lower compared to control (p <  0.05). There was no significant difference in nasal bleeding when the packing was removed between the two groups (p > 0.05) after surgery. Within the first week after surgery, there was no significant difference in occurrence of nasal malodor (p > 0.05).
Conclusion:  Application of budesonide nasal irrigation alleviates post-operative symptoms, reduces inflammation and improves treatment outcomes.  Further studies will be required to comprehensively investigate the dose effect of budesonide.
