Published: April 2024

Abstract
The effectiveness of floating breakwaters in reducing waves can be achieved by adjusting the placement of structures according to conditions in the field. The effect of floating breakwater layout will affect the transmission and reflection waves. This study numerically modeled a floating breakwater with 0° porosity using Flow-3D to determine the reflection and transmission waves. The layout under study is a connection of three single-model floating breakwaters (I-shaped), connected by connectors made of coated wire rope in three variations of placement for wave incident angles (0°, 30°, and 60°). The study results show that the greater the angle of inclination of the structure causes an increase in the transmission coefficient and the lower the reflection coefficient. Floating breakwater layouts with tilt angles of 0°, 30°, and 60° have transmission coefficient values that differ not too significantly, where the tilt angle of 60° is more effective at damping waves compared to other tilt angles.

Published: April 2024

Abstract
This study aims to design a prototype of water pump station control in a polder system using IoT and artificial intelligence at Sringin Polder system. The design includes the hydrology analysis to define how the pump station should be set to control the level of the embankment. The second part is the IoT system that contain the sensor and interface to the water pump in the pump station. The third part is the core of control system using hybrid fuzzy neural network as the heart of the control system. Pump station has important role in the polder system to control the level of water in embankment. Five pumps in the system should operate based on schedule determined by the hydrology modelling. Since it is located in separate area with the control room, MQTT protocol is used to deliver data communication in both ways, to send the water level detected by ultrasonic sensor and also to switch on and off the pump by control system. In other hand, hybrid fuzzy neural network is used to control the pump scheduling based on water level detected.

Published: April 2024

Abstract
Geopolymer concrete made from fly ash as a substitute to Portland cement is a relatively new and environmentally friendly material. Various studies have revealed that geopolymer concrete is more brittle than Portland cement concrete. To increase its ductility in structures, geopolymer concrete needs to be confined. However, confinement models for geopolymer concrete are still limited. This paper compares some confinement models with stress-strain data obtained from laboratory tests. The confinement models investigated here were Ganesan et al. which was proposed for geopolymer concrete, and Mander et al. which were to Portland cement concrete. The comparison was conducted on the stress-strain action, including the characteristics from the ascending curve, the maximum stress and its corresponding strain, the descending curve. The outcomes show that the values of initial stiffness of geopolymer concrete simulated by models are higher than the actual values obtained from the tests and other confinement models. However, the maximum stress and the maximum strain values obtain from the models under estimate the test outcomes.
Analysis Of Water Availability In The Environmental Water Sources Of The Aikmampat River Sub-Region In Fulfilling The Need For Clean Water In The South Part Of Lombok Island

Published: April 2024

AbstractClean waters infrastructure functions in utilizing water resources for the general public. General planning for clean water development in this study is focused on water resource management in the form of stewardship, provision, use, development, and exploitation of water resources considering that the social, environmental, and economic functions of water resources cannot be separated. To estimate water availability for biota or ecosystems, we use the discharge at Q-95% at each weir. To analyze waters availability for biota, we refer to the flow duration curve graph. We have calculated the water balance for the Lingkung sub watershed of Aik Mampat, taking into account the surface water sources. The water balance has been calculated under two conditions: existing conditions (which include needs of irrigation and existing water needs of raw) and planned conditions (which consider the development of a drinking water management system). The level of service in the south coast area for 5 sub-districts in the development plan year was obtained at 150 l/s and a maximum of 270,75 l/s in the plan year. The maximum irrigation water requirement is 320 l/s with an average of 50 l/s. The water balance in the Aikmampat Sub-watershed (Lingkung surface water source) saw a decrease in the minimum FK (Reliability Factor) from the existing condition of 40% to 25% (plan condition). Water rotation arrangements in the spider channel need to be carried out, especially in June and July.
Floating House Platform Stability Test with a Lightweight Concrete Cover Made of Expanded Polystyrene System (EPS)
Authors: Cahyono D. B. 
Published: April 2024

Abstract
Coastal area which affected by floods and tides has problems about safety and comfortable environment. The world of floating construction has introduced substructure foundations made from expanded polystyrene system (EPS) with a lightweight concrete cover. The styrofoam platform must meet the buoyancy, stability and center height test requirements. The research aims to analyze the magnitude of the buoyant force (Fa) against downward force due to the load weight on platform. The platform is strong and stable when upward force (Fa) is greater than total structure weight (G). The object will float if buoyant force (Fa) is greater than the gravitational force (g). The balance is stable if center of object gravity (Bo) is below the center of buoyancy (Ao), otherwise it will be in arbitrary balance. The height of centrum can be determined m > 0, means the object is stable. The research results show that 6.12x5.12x0.68m Styrofoam platform with a buoyancy force of 18,246.6 kg is able to withstand an additional load of 3647.62 kg with an SF value of 2.59. It means there is a linear relationship between magnitude of loading value and sinking height of Styrofoam platform. The safety factor value decreases as the sinking height of platform increases. The stability value of Fa/G is 3.01>1.2. The metacentrum’s height is 16.531 > 0, so the platform with a lightweight concrete cover is declared stable and safe to use.

Abstract
The realization of sustainable development is the responsibility of every construction element to carry out the prevention of development activities that have the potential to damage and cause environmental problems. Alignment of the ongoing construction project with the maintenance of environmental balance can be carried out through environmental management and monitoring in construction site. One of them, through an assessment and evaluation related to the implementation of sustainable construction, is one of the efforts that can be made to prevent environmental damage due to construction activities. The guideline or measuring tool is the Green Construction Site Index (GCSI) to evaluate six building construction which are grouped into two categories (residential and non-residential buildings). A quantitative measuring instrument to measure five elements consisting of waste minimization, sustainable green construction, resource management, understanding of construction waste and environmental performance on construction as parameters in the implementation of construction activities. The average values obtained from the two categories of buildings based on five elements respectively are 4.11, 3.94, 4.27, 3.85, and 4.20.
Behavior of Modified Strut-and-Tie Model (STM) on Concrete Beams
Authors: Sugianto A , Antonius A , Taufik S 
Published: April 2024

Abstract
Reinforced concrete components are generally designed to withhold shear and bending based on the assumption at strain varies linearly in a section where the applied force is a combination of shear with bending, torsion, or normal forces. The behavior of shear failure in reinforced concrete beams is very different from that in flexural failure. Shear failure is brittle without warning in the form of significant deflection, resulting in diagonal cracks in the beam then the shear force mechanism will be contributed by an arching action where this action can provide a reserve capacity large enough for the beam to carry the load. Nonlinear analysis using the strut-and-tie method is particularly useful for shear-critical structures where classical beam theory is not valid due to significant shear deformations. Strut-and-Tie Model research which is applied to concrete (25 MPa), also uses the optimal configuration FEM software tool from Strut-and-Tie which leads to the efficiency of Strut-and-Tie. The results of the optimization and modification of the Strut-and-Tie Model on concrete will also be applied to the experimental models tested until they fail so that the optimal conditions for numerical models will be obtained.
Based on the analysis result of element model using ANSYS computational assistance program, the ultimate flexural capacity of the beam model will increase depending on the used STM model and inclination angle (Φ), at the STM type 2 high < 1000 mm, inclination angle (Φ) 45° having a decrease in ultimate shear capacity (Vu) of 49,31% against type 1, at the STM model 3 high < 1000 mm, with inclination angle (Φ) 45° having an increase ultimate shear (Vu) of 4,14% against type 1. Stress pattern performed bottle shape in line with diagonal strut. Ductility capacity will be decreased at inclination angle <45° of 27,11%, at inclination angle >45° will be decreased of 55,67%,

Published: April 2024

Abstract
This work presents a novel three-dimensional fractal model designed specifically for morphological analysis of specimens made by the EDM. Within the 3D fractal framework, an algorithm is developed to estimate fractal parameters such as fractal dimension and periodic length. AISI 316 stainless steel, dielectric media, electrode materials, and powder variations were used in experimental trials to validate the 3D fractal model. Fixed pulse time ratios were used to control the EDM process. The specimen having the lowest fractal dimension, the shortest periodic length, the least amount of surface roughness, and the least amount of ten-point height was discovered to be the one machined using kerosene oil dielectric, brass electrode, graphite powder, and 1.0 pulse ratio time. On the other hand, the specimen machined using copper electrode, graphite powder, transformer oil dielectric, and 1.5 pulse ratio time produced the largest periodic length, maximum surface roughness, fractal dimension, and ten-point height. The developed 3D fractal model evaluates the EDM process well and provides insightful information on how to improve surface properties.

Published: April 2024

Abstract
Fe2O3/TiO2/AC nanocomposites were successfully synthesized via a sol–gel method, and their efficacy in decomposing methyl orange via adsorption-photocatalytic processes was reported for the first time in this study. Systematic exploration of the physicochemical properties impacting photocatalytic activity was conducted through x-ray diffraction, scanning electron microscopy—energy-dispersive x-ray spectroscopy, and Fourier transform infrared spectroscopy (FTIR) characterizations. The study revealed that the discoloration of methyl orange resulted from a synergistic interplay between adsorption and photocatalysis. The incorporation of Fe2O3 nanoparticles significantly elevated photocatalytic activity by 70%, with additional enhancement observed upon the introduction of activated carbon (AC) particles. The synergistic effects of AC adsorption and TiO2/Fe2O3 photocatalysis exhibited remarkable efficiency in degrading methyl orange under visible light irradiation. The trial functioning of Fe2O3 and AC in the TiO2/Fe2O3/AC composite, which serves as an adsorbent, an electron trap, and a co-catalyst providing active sites, significantly improved photocatalytic activity. These findings not only contribute to understanding the crucial role of composite TiO2 in conjunction with metal and carbon-based co-catalysts but also hold valuable implications for advancing research in the development of adsorption-photocatalytic systems for wastewater treatment.
Pacemaker effects on online social rhythms on a social network

Published: April 2024

Abstract
The dynamics of coupled oscillators in a network are a significant topic in complex systems science. People with daily social rhythms interact through social networks in everyday life. This can be considered as a coupled oscillator in social networks, which is also true in online society (online social rhythms). Controlling online social rhythms can contribute to healthy daily rhythms and mental health. We consider controlling online social rhythms by introducing periodic forcing (pacemakers). However, theoretical studies predict that pacemaker effects do not spread widely across mutually connected networks such as social networks. We aimed to investigate the characteristics of the online social rhythms with pacemakers on an empirical online social network. Therefore, we conducted an intervention experiment on the online social rhythms of hundreds of players (participants who were pacemakers) using an avatar communication application (N = 416). We found that the intervention had little effect on neighbors’ online social rhythms. This may be because mutual entrainment stabilizes the neighbors’ and their friends’ rhythms. That is, their online social rhythms were stable despite the disturbances. However, the intervention affected on neighbors’ rhythms when a participant and their neighbor shared many friends. This suggests that interventions to densely connected player groups may make their and their friends’ rhythms better. We discuss the utilization of these properties to improve healthy online social rhythms.

Abstract

Introduction
Severe acute respiratory syndrome coronavirus 2 is a viral respiratory infection that can cause systemic disorders and lead to death, particularly in older people. Proton pump inhibitors (PPIs) increase the risk of enteric and lung infections. Considering the broad use of PPIs in older people, the potential role of PPIs in COVID-19 could be of dramatic significance. The objective of our study was to evaluate the link between PPIs and severe COVID-19 in older people.

Method
We performed a retrospective cohort study, including all patients aged ≥65, hospitalised for a diagnosis of COVID-19. Epidemiological, clinical and biological data were extracted and we performed an Inverse Probability of Treatment Weighing method based on a propensity score.

Results
From March 2020 to February 2021, a total of 834 patients were included, with a median age of 83 and 52.8% were male. A total of 410 patients had a PPIs prescription, 358 (87.3%) were long-term PPIs-users and 52 (12.7%) were recent PPIs-users. Among PPIs-users, 163 (39.8%) patients developed severe COVID-19 versus 113 (26.7%) in PPIs-non users (odds ratio (OR) = 1.59 [1.18–2.14]; P &lt; 0.05). Moreover, the double dose PPI-users had a higher risk of developing severe COVID-19 (OR = 3.36 [1.17–9.66]; P &lt; 0.05) than the full dose PPI-users (OR = 2.15 [1.22–3.76]; P &lt; 0.05) and the half dose PPI-users (OR = 1.64 [1.13–2.37]; P &lt; 0.05).

Conclusion
Our study reports evidence that the use of PPIs was associated with an increased risk of severe COVID-19 in older people.
Assessing the 5-year persistence in positive clinical response with innovative psoriasis treatments: a network meta-analysis of Psoriasis Area and Severity Index score
Authors: Husein-ElAhmed Husein , Husein-ElAhmed Sara 
Published: April 2024

Abstract

Background
Psoriasis is a chronic skin condition, for which the approval of several biologics has made a dramatic impact. Despite their initial treatment effectiveness, the challenge lies in understanding the long-term responses, as they may diminish over time. Limitations of drug survival analysis warrant the application of additional outcomes to fully capture the performance of a biologic.

Objectives
To provide a broader perspective on the global landscape of biologic agents’ persistence in positive clinical response by comparing innovative therapies over a 5-year period through a systematic review and network meta-analysis.

Methods
We comprehensively identified studies in PubMed, Embase, Scopus and ClinicalTrials.gov. We defined two outcomes: (i) ‘persistence at optimal response’ (POR) or ‘clinical remission’, and (ii) ‘persistence at suboptimal response’ (PSR) or ‘low disease activity’. Outcomes were measured as the proportions of patients with continuous exposure to a biologic who achieved ≥ 90% or 100% improvement in Psoriasis Area and Severity Index at the end of the predefined 5-year follow-up period.

Results
Eleven publications, comprising 18 randomized controlled trials and 11 202 patients, met the inclusion criteria and were included in the network meta-analysis. In the ranking analysis, guselkumab exhibited the highest cumulative probability of POR (0.84), followed by ixekizumab (0.82) and risankizumab (0.76). Conversely, etanercept (0.42), brodalumab (0.36), apremilast (0.25) and placebo (0.026) showed the lowest cumulative probabilities of POR. For PSR, guselkumab (0.86), ixekizumab (0.75) and risankizumab (0.71) also ranked highest, while brodalumab (0.42), secukinumab (0.23), etanercept (0.19) and placebo (0.019) presented the lowest PSR probabilities.

Conclusions
The highest rates of persistence with clear or almost clear skin can be expected with guselkumab, ixekizumab and risankizumab compared with other biologics. The proposed proxy definitions of long-term persistence (POR and PSR) are reliable measures of patients being successfully treated that warrant further exploration and validation.

Abstract
Peri-implantitis (PI) and periodontitis (PD) are common oral inflammatory diseases, which seem to exhibit critical differences in some of their molecular features. Thus, we assessed the immune cell composition of PI and PD lesions and the corresponding inflammatory profile in soft tissues and crevicular fluid. PI, PD, and control patients were recruited (n = 62), and soft tissue biopsies were collected during surgery. Crevicular fluid around implant or tooth was collected. The proportions of major immune cell populations in tissues were analyzed by flow cytometry, and the inflammatory profile in tissue and crevicular fluid by a multiplex immunoassay. No significant difference was seen between PI and PD lesions in the proportions of immune cells. PI tissues showed an increased frequency of B cells in comparison with control tissues, along with higher levels of IL-1β, TNF-α, IL-4, and BAFF in tissue and crevicular fluid. Moreover, TNF-α, IL-17A, and BAFF were higher in PI tissues, but not in PD, than in control tissues. The immune cell composition did not differ significantly between PI and PD, but an enhanced inflammatory profile was seen in PI tissue. PI lesions were enriched in B cells, and displayed increased levels of IL-1β, TNF-α, IL-4, and BAFF in both tissue and crevicular fluid.

Abstract
The Zr metal–organic framework (MOF) UiO-66 was shaped into beads using chitosan and P3O105− as a cross-linker. The obtained UiO-66–chitosan beads showed decreases in pore size and Brunauer–Emmett–Teller (BET) surface area but enhanced N2 adsorption energy with retention of Zr-ligand connectivity. This finding will provide an important insight into the practical application of MOFs.

Abstract

Background and Aims
Coexisting atrial fibrillation (AF) and cancer challenge the management of both. The aim of the study is to comprehensively provide the epidemiology of coexisting AF and cancer.

Methods
Using Dutch nationwide statistics, individuals with incident AF (n = 320 139) or cancer (n = 472 745) were identified during the period 2015–19. Dutch inhabitants without a history of AF (n = 320 135) or cancer (n = 472 741) were matched as control cohorts by demographic characteristics. Prevalence of cancer/AF at baseline, 1-year risk of cancer/AF diagnosis, and their time trends were determined. The association of cancer/AF diagnosis with all-cause mortality among those with AF/cancer was estimated by using time-dependent Cox regression.

Results
The rate of prevalence of cancer in the AF cohort was 12.6% (increasing from 11.9% to 13.2%) compared with 5.6% in the controls; 1-year cancer risk was 2.5% (stable over years) compared with 1.8% in the controls [adjusted hazard ratio (aHR) 1.52, 95% confidence interval (CI) 1.46–1.58], which was similar by cancer type. The rate of prevalence of AF in the cancer cohort was 7.5% (increasing from 6.9% to 8.2%) compared with 4.3% in the controls; 1-year AF risk was 2.8% (stable over years) compared with 1.2% in the controls (aHR 2.78, 95% CI 2.69–2.87), but cancers of the oesophagus, lung, stomach, myeloma, and lymphoma were associated with higher hazards of AF than other cancer types. Both cancer diagnosed after incident AF (aHR 7.77, 95% CI 7.45–8.11) and AF diagnosed after incident cancer (aHR 2.55, 95% CI 2.47–2.63) were associated with all-cause mortality, but the strength of the association varied by cancer type.

Conclusions
Atrial fibrillation and cancer were associated bidirectionally and were increasingly coexisting, but AF risk varied by cancer type. Coexisting AF and cancer were negatively associated with survival.
