Published: May 2024

There is an essential clinical need to develop rapid process scaffolds to repair bone defects. The current research presented the development of calcium zirconium silicate/polycaprolactone for bone tissue engineering utilising melt extrusion-based 3D printing. Calcium zirconium silicate (CZS) nanoparticles were added to polycaprolactone (PCL) porous scaffolds to enhance their biological and mechanical properties, while the resulting properties were studied extensively. No significant difference was found in the melting point of the samples, while the crystallisation temperature points of the samples containing bioceramic increased from 36.1 to 40.2 °C. Thermal degradation commenced around 350 °C for all materials. According to our results, increasing the CZS content from 0 to 40 wt.% (PC40) in porous scaffolds (porosity about 55–62%) improved the compressive strength from 2.8 to 10.9 MPa. Furthermore, apatite formation ability in SBF solution increased significantly by enhancing the CZS percentage. According to MTT test results, the viability of MG63 cells improved remarkably (~29%) in PC40 compared to pure PCL. These findings suggest that a 3D-printed PCL/CZS composite scaffold can be fabricated successfully and shows great potential as an implantable material for bone tissue engineering applications.

Published: May 2024

The majority of investigations on microbial communities from various environments are presently built on culture-independent methods. Many studies point to the pivotal, selective role of primers targeting hypervariable regions of 16S rRNA in the metabarcoding of bacteria, including cyanobacterial communities. The selectivity of primers designed to amplify targeted regions of the 16S rRNA gene, which has been highlighted by many authors, limited effective amplification. Moreover, the type and specificity of the studied material can also negatively influence the results of 16S metabarcoding. Most of the studies of cyanobacterial communities have been performed for planktonic microbial communities that are often represented by common, well-studied species. In this study, we present the results of 16S metabarcoding analysis using three primer pairs—two already well-known and a third designed in this study—that amplify divergent regions of the 16S rRNA gene (V3–V4, V4–V6, V6) for benthic, microbial mat-forming cyanobacteria communities. Such communities can be a source of toxigenic cyanobacterial taxa and should be monitored with adequate primers. The comparison of three primer pairs suggested that those designed within the present study describe the structure and composition of highly heterogeneous cyanobacterial mats’ communities better than the others.

Published: May 2024

Even though the role of ecosystem services is known, the identification and assessment of water-related services is usually absent or often less represented as an ecosystem service. Progress in water quality indicator definition and compliance with regulations has been made; however, the relationship between water quality degradation and benefits to individuals and ecosystems remains little recognized. Here, we present an assessment of water quality and identification of ecosystem services in south-east Mexico. This study was performed within the geohydrological reserve zone of the Ring of Sinkholes, Yucatán Peninsula. Thirteen ecosystem services provided by the aquifer were identified. Water quality was evaluated in sinkholes based on national and international norms, considering different sinkhole uses. Results show a dynamic system, without saltwater intrusion and good to excellent water quality. The research demonstrates the relationship between ecosystem services and water quality, showing pressure in services related to uses for aquatic life protection and to a lesser extent those related to consumption. Current productive activities showed no pressure at this time. Principal Component Analysis (PCA) and Analysis of Variance (ANOVA) exhibited a significant difference in parameters and campaigns, but not between sinkholes. A long-lasting monitoring program for water quality is necessary to accurately evaluate the status of ecosystem services provided by the aquifer. Moreover, it is necessary to assess aquifers as ecosystems with economic, ecologic and socio-cultural importance. Effective water governance requires a balance of interests between all parties, within a legal and institutional framework.
Repeatability of Hydroacoustic Results versus Uncertainty in Assessing Changes in Ecological Status Based on Fish: A Case Study of Lake Widryńskie (Poland)
Authors: Hutorowicz Andrej
Published: May 2024

Assessments of changes in the ecological state of aquatic ecosystems are always burdened with uncertainty, which results from environmental reasons and poor repeatability of measurement results of elements enabling the assessment. This study determines the uncertainty related to the elements of the assessment of the hydroacoustic structure of fish communities’ (1) vertical target strength distribution (TS) in two-meter layers of water and (2) changes in the area where fish were recorded (which was determined on the basis of maps of their distribution in 2 m deep water layers). The object of this study was a lake (depth: 27 m) in which at the end of June 2016 the O2 concentration was <1.4 mg L−1 below 8 m depth, which resulted in the accumulation of fish to a depth of 6 m. Hydroacoustic acquisition was carried out along transects arranged in the east–west (WE), north–south (NS), and zigzag (ZZ) directions in three repetitions. It was shown that the empirical probability of obtaining statistically different results was 2/9 when (1) Kendall’s τ coefficient, used to determine the similarity of the TS distribution, was less than 0.7—moderate correlation—and (2) fish occurrence areas in two cases (WE and ZZ on the third day of research) in layers 2–4 m and 4–6 m differed statistically significantly from the average area for all repetitions by 10–14% and 56–66% (p < 0.05), respectively. The obtained results indicate quite good repeatability of acoustic measurements; however, in order to reduce the uncertainty, it is recommended that tests be conducted in this type of lake in three series of measurements.

Published: May 2024

The proximity of freshwater ecosystems to anthropogenic activities makes them one of the most threatened environments by plastic pollution in the form of microplastics (MPs). Therefore, it is crucial to identify the primary drivers of MP dynamics in rivers to enhance their management. This work analyzed the concentration of MPs in water and sediments and evaluated the influence of land use and its relationship with the main biotic indices employed to assess the water quality of rivers. This research was carried out in four different catchments, with three sampling points established in each river basin. The results revealed that MPs were ubiquitous across all locations, with concentrations ranging from 0.10 to 35.22 items m−3 in waters and from 26 to 643 items Kg−1 in sediments. The highest concentration of MPs both in water and sediments were found in the Lagares River (35.22 items m−3 and 643 items Kg−1), while the lowest concentrations were found in the Miñor River for water (0.10 items m−3) and Tea River for sediments (138 items Kg−1). Urbanization degree was identified as the primary driver of MP pollution in water, whereas population density correlated with sediment pollution levels. These findings explain the elevated MPs abundance in the more urbanized and populated Gafos and Lagares rivers compared to the relatively pristine Miñor and Tea rivers. Furthermore, the presence of MPs in sediments was found to negatively impact the most sensitive benthic macroinvertebrate taxa, as evidenced by lower values of the IASPT and EPT indices at sampling points with higher sediment MPs concentrations (Gafos and Lagares).
The Effects of Climate Change on Streamflow, Nitrogen Loads, and Crop Yields in the Gordes Dam Basin, Turkey
Authors: Özdemir Ayfer , Volk Martin , Strauch Michael , Witing Felix
Published: May 2024

The Mediterranean region is highly vulnerable to climate change. Longer and more intense heatwaves and droughts are expected. The Gordes Dam in Turkey provides drinking water for Izmir city and irrigation water for a wide range of crops grown in the basin. Using the Soil and Water Assessment Tool (SWAT), this study examined the effects of projected climate change (RCP 4.5 and RCP 8.5) on the simulated streamflow, nitrogen loads, and crop yields in the basin for the period of 2031–2060. A hierarchical approach to define the hydrological response units (HRUs) of SWAT and the Fast Automatic Calibration Tool (FACT) were used to reduce computational time and improve model performance. The simulations showed that the average annual discharge into the reservoir is projected to increase by between 0.7 m3/s and 4 m3/s under RCP 4.5 and RCP 8.5 climate change scenarios. The steep slopes and changes in precipitation in the study area may lead to higher simulated streamflow. In addition, the rising temperatures predicted in the projections could lead to earlier spring snowmelt. This could also lead to increased streamflow. Projected nitrogen loads increased by between 8.8 and 25.1 t/year. The results for agricultural production were more variable. While the yields of poppy, tobacco, winter barley, and winter wheat will increase to some extent because of climate change, the yields of maize, cucumbers, and potatoes are all predicted to be negatively affected. Non-continuous and limited data on water quality and crop yields lead to uncertainties, so that the accuracy of the model is affected by these limitations and inconsistencies. However, the results of this study provide a basis for developing sustainable water and land management practices at the catchment scale in response to climate change. The changes in water quality and quantity and the ecological balance resulting from changes in land use and management patterns for economic benefit could not be fully demonstrated in this study. To explore the most appropriate management strategies for sustainable crop production, the SWAT model developed in this study should be further used in a multi-criteria land use optimization analysis that considers not only crop yields but also water quantity and quality targets.
Integrated Time-Dependent Analysis of a Hydraulic Structure on Soft Foundations during Construction
Authors: Xu Chao , Ye Liang , Pan Suli , Luo Wen
Published: May 2024

An integrated model that considers multiphysics is necessary to accurately analyze the time-dependent response of hydraulic structures on soft foundations. This study develops an integrated superstructure–foundation–backfills model and investigates the time-dependent displacement and stress of a lock head project on a soft foundation during the construction period. Finite element analyses are conducted, incorporating a transient thermal creep model for concrete and an elasto-plastic consolidation model for the soil. The modified Cam-clay model is employed to describe the elasto-plastic behavior of the soil. Subsequently, global sensitivity analyses are conducted to determine the relative importance of the model parameters on the system’s response, using Garson’s and partial derivative algorithms based on the backpropagation (BP) neural network. The results indicate that the integrated system exhibits pronounced time-dependent displacement and stress, with dangerous values appearing during specific periods. These values are easily neglected, highlighting the importance of integrated time-dependent analysis. Construction activities, particularly the backfilling process, could cause a sudden change in stress and significantly impact the stress redistribution of the superstructure. Additionally, the mechanical properties of concrete have a significant impact on the stress on the superstructure, while the mechanical properties of the soil control the settlement of the integrated system.

Authors: Li Xiaoning , Zhang Ziyin , Li Qingliang , Zhu Jinlong
Published: May 2024

This study introduces an innovative deep learning model, Residual-EnDecode-Feedforward Attention Mechanism-Long Short-Term Memory (REDF-LSTM), designed to overcome the high uncertainty challenges faced by traditional soil moisture prediction methods. The REDF-LSTM model, by integrating a residual learning encoder–decoder LSTM layer, enhanced LSTM layers, and feedforward attention, not only captures the deep features of time series data but also optimizes the model’s ability to identify key influencing factors, including land surface features, atmospheric conditions, and other static environmental variables. Unlike existing methods, the innovation of this model lies in its first-time combination of the residual learning encoder–decoder and feedforward attention mechanisms in the soil moisture prediction field. It delves into the complex patterns of time series through the encoder–decoder structure and accurately locates key influencing factors through the feedforward attention mechanism, significantly improving predictive performance. The choice to combine the feedforward attention mechanism and encoder–decoder with the LSTM model is to fully leverage their advantages in processing complex data sequences and enhancing the model’s focus on important features, aiming for more accurate soil moisture prediction. After comparison with current advanced models such as EDLSTM, FAMLSTM, and GANBiLSTM, our REDF-LSTM demonstrated the best performance. Compared to traditional LSTM models, it achieved an average improvement of 13.07% in R2, 20.98% in RMSE, 24.86% in BIAS, and 11.1% in KGE key performance indicators, fully proving its superior predictive capability and potential application value in precision agriculture and ecosystem management.
Excessive Eutrophication as a Chemical Barrier for Fish Fauna Dispersion: A Case Study in the Emblematic Tietê River (São Paulo, Brazil)
Authors: Urbanski Bruna , Nogueira Marcos
Published: May 2024

The Tietê River receives most of the effluents and diffuse wastes from the São Paulo metropolis (21.9 million inhabitants). The study aimed to assess the extent to which environmental changes affected the fish fauna. We compared, in rainy and dry seasons, three sites in Tietê and three in tributaries with much better water quality conditions. No physical barriers exist between the sites. Fish were sampled with gillnets (exposed overnight) and the assemblage’s ecological attributes calculated. Water depth, transparency, temperature, electrical conductivity, dissolved oxygen, turbidity, total dissolved solids, pH, redox potential, total phosphorus, total nitrogen, and chlorophyll were simultaneously determined. Low oxygen concentrations (near zero in the rainy period), and the opposite for nutrients and total solids, separated the predominantly hypereutrophic Tietê from the tributaries (PCA). Differences in the fish assemblages were also evidenced (nMDS), including a higher richness per sample in tributaries (11 to 14 spp.) compared to Tietê (3 to 4 spp.). Siluriformes with accessory breathing dominated in Tietê and the highly tolerant detritivorous Prochilodus lineatus (the main commercial fish) was the only species found in all sites. The species correlated positively with oxygen in the tributaries and with turbidity, redox potential, and nutrients in Tietê (DistLM) (rainy season). Recovery measures are urgently required.

Published: May 2024

Turbulent water jets remain a critical study area, particularly the relation of the water flow with air entrainment and its role in energy dissipation at different hydraulic structures. Plunge pools, formed by the impact of jets on water cushions, play a pivotal role in energy dissipation. Understanding the complex flow dynamics within these pools is essential for designing efficient hydraulic structures. In this research, we present a comprehensive investigation of different numerical simulations, defining two-phase (air-water) in different ways, and them compare with experimental measurements. The primary objective is to analyze the pressure distribution at the bottom of a plunge pool induced by a vertical jet and understand the importance of accurately defining air-water flow in the dynamics of the jet into the pool. Our study bridges the gap between empirical data and computational modeling, shedding light on the intricate behavior of such flows with different method-based solvers: VOF, sub-grid, and multi-phase Euler. Various computational domains, mesh configurations, and analyses spanning different time periods, frequencies, and scales were considered.
Efficiency Analysis of Hybrid Extreme Regenerative with Supercapacitor Battery and Harvesting Vibration Absorber System for Electric Vehicles Driven by Permanent Magnet Synchronous Motor 30 kW
Authors: Techalimsakul Pataphiphat , Sawetmethikul Pakornkiat
Published: May 2024

This research presents an approach to the hybrid energy harvesting paradigm (HEHP) based on suspended energy harvest. It uses a harvesting vibration absorber (HVA) with an SC/NMC-lithium battery hybrid energy storage paradigm (SCB-HESP) equipped regenerative braking system (SCB-HESP-RBS) for electric vehicles 2 tons in gross weight (MEVs) driven by a 30 kW permanent magnet synchronous motor (PMSM). During regenerative braking, the ANN mechanism controls the RBS to adjust the switching waveform of the three-phase power inverter, and the braking energy transfers to the energy storage device. Additionally, a supercapacitor (SC) equipped with HVA can absorb energy from vehicle vibrations and convert it into electrical energy. The energy-harvesting efficiency of MEV based on SCB-HESP-RBS using HVA suspended energy harvesting enhances the efficiency maximum to 50.58% and 15.36% in comparison to MEV with only-HVA and SCB-HESP-RBS, respectively. Further, the MEV with SCB-HESP-RBS using HVA has a driving distance of up to 247.34 km (22.5 cycles) when compared with SCB-HESP-RBS (214.40 km, 19.5 cycles) and only-HVA (164.25 km, 15 cycles).
Investigating Calico Crayfish (Faxonius immunis Hagen, 1870) as a possible “sleeper” invasive species in northern Wisconsin, United States

Published: May 2024

“Sleeper” invaders are non-native populations that experience time-lags post-establishment before subsequent spread or negative impacts, challenging managers to differentiate harmless non-native species from invasive species. In lakes of northern Wisconsin, United States, Rusty Crayfish (Faxonius rusticus Girard, 1852) has dominated as an invasive species for decades, but this species has recently experienced population declines. Following these F. rusticus declines, we rediscovered in 2020 a population of non-native Calico Crayfish (Faxonius immunis Hagen, 1870) that had not been documented since the 1970s. Declining F. rusticus populations may create opportunities for F. immunis spread to other lakes and impacts as a sleeper invader. We conducted additional sampling in summer 2021 that suggests F. immunis remains isolated in only one lake within this watershed. We used mitochondrial DNA barcoding to confirm these crayfish were F. immunis and had not been misidentified as a congener. Next, we investigated whether biotic interactions with F. rusticus may have prevented F. immunis spread over the past several decades. We measured agonistic behaviors using F. immunis and F. rusticus pairs in the laboratory, and then modeled differences in aggression between species while controlling for size and reproductive form. We found that F. rusticus were consistently dominant over F. immunis, suggesting that competition with an established hyper-abundant invasive species may have restricted past spread by F. immunis. Managers and policy makers should consider whether precautionary actions against F. immunis are warranted while the population of this species remains small and localized, especially in the context of F. rusticus declines.
Narrative Policy Analysis: What is Behind The Movement of Capital City of Indonesia
Authors: Akeda Harriswara , Muslim Muh Aziz
Published: May 2024

The relocation of the Indonesian Capital from Jakarta to Nusantara in North Penajam Paser has generated both support and opposition. The urgency of the idea has been criticized as not taking into account the current conditions, which is still recovering from the pandemic and facing uncertainties in the global economic situation. To understand this situation, this study used narrative policy framework method to analyze the government's narrative in implementing capital relocation policy, as compared to the counter-narrative conveyed by the community. The government believes that relocation is the best solution to resolving the pressing issues of economic disparity and environmental changes on Java Island. They also claim that the new capital would be a showcase of Indonesia's diversity to the world. On the other hand, the community views policy as being unfavorable to their interests, more business-oriented, and politically driven. The government is seen as unresponsive to the community's needs. The results showed that there was a gap between narrative of capital relocation policy conveyed by the government and the community who opposed this policy. In addition, the government's failure to involve the community in the formulation of policy has resulted in conflicting interests and different perspectives during the implementation stage.

This article aims to evaluate the formulation of the Regional Revenue and Expenditure Budget (APBD) in West Sumba Regency, specifically during the fiscal year 2019/2020. The research focuses on the stages of APBD formulation, namely the drafting of APBD, the formulation of the General Budget Policy (KUA), the formulation of the Temporary Budget Ceiling (PPAS), the preparation of Regional Working Plans and Budgets of Regional Apparatus (RKA-SKPD), the verification of RKA-SKPD, and the enactment of the Regional Regulation on the APBD (Ranperda APBD). The qualitative method with a descriptive approach is used in this study. Data was collected through interviews and document studies. The Miles and Huberman data analysis method was employed. The findings indicate that, overall, the APBD formulation process adhered to the applicable legal provisions. However, several shortcomings were identified. Firstly, there were delays in the evaluation of the formulation. Secondly, many of the aspirations of the West Sumba community were not accommodated in the KUA during the APBD formulation. Thirdly, inconsistencies between Regional Medium-Term Development Plans (RKPD) and RKA SKPD were due to inadequate socialization during the preparation of RKA-SKPD. Fourthly, RKA-SKPD verification was hurried, impacting the effectiveness of the verification process. Finally, the West Sumba APBD Ranperda should have been socialized to the public before being ratified by the Regional People's Representative Council (DPRD), which was not carried out. These findings highlight the limited involvement of actors in the formulation of the West Sumba APBD due to the dominant role of the government in the formulation process. This contrasts with the policy network theory, which emphasizes the significance of involving various actors in decision-making to enhance the quality of decisions taken.

This study evaluates the phenomenon of vigilantism in Indonesia, focusing on the juridical aspects of sanctions against perpetrators of criminal theft resulting in death. The research reveals that the current criminal regulations related to vigilantism, as outlined in Articles 170, 351, 406, and 338 of the Indonesian Criminal Code (KUHP), have not fully provided decisive penalties. Analysis of the verdict in Decision Number 8/Pid.B/2018/PN. Bks indicates that the perpetrator was charged under Article 170 paragraphs (1) and (2) jo Article 55 paragraph (1) of the KUHP, receiving an 8-year prison sentence for vigilantism leading to death. Despite the verdict being based on the fulfillment of the elements of the charges, the research asserts that law enforcement against vigilantism has not yet demonstrated its effectiveness. In this context, there is a need for a legal process more aligned with justice and legal certainty for the victims. The research methodology employed is Normative Juridical, utilizing secondary data and expert interviews. The findings highlight the importance of effective law enforcement against vigilantism that meets the elements of Article 170 or 351 of the KUHP to achieve justice for the victims.

As one of the most well-known types of drink throughout the world, it is not surprising that the presence of tea in Yogyakarta Palace is high. Tea is always served in the Sultan and family's private dishes, traditional ceremonies, and state banquets. In other countries, tea has even become an identity and a diplomatic tool. Seeing this phenomenon, this research was created to dig deeper into the existence of tea in the Yogyakarta Palace, especially at state banquets and its relation to a form of culinary diplomacy known as gastrodiplomacy. In this qualitative research, it was found that tea was always served as choice of drink at state banquets. However, until now there has not been a special format or procedure for a tea party to entertain state guests. It would be interesting if in the future the palace could develop a Yogyakarta Palace style tea reception in order to maximize the potential for gastrodiplomacy which could have various positive implications for collaboration in various needed sectors.

This article aims to describe the process of vote buying and selling at 2 TPS in Kampung Baru Village and analyze the political relations of incumbent candidates in Kampung Baru Village. This research uses a qualitative descriptive approach with a case study method. The theories used are vote buying, patronage, and clientelism. The research results show that vote buying at 2 TPS in Kampung Baru Village stems from low voter participation. There were 216 voters who came to exercise their voting rights out of 872 voters. Seeing the low voter participation, the Head of Kampung Baru Village as the incumbent's success team asked the KPPS to vote on the remaining ballot papers. KPPS officers agreed and asked the incumbent's success team to discuss it with the PPS chairman of Kampung Baru Village.

During the postpartum period, midwives not only assess the physical examination and breastfeeding process, but also must assess the emotional well being and social support of the postpartum mother. The Continuity of Care (CoC) midwifery care model makes mothers get to know their caregivers better, this is one of the midwifery care models that provides services to help women build relationships with their caregivers. Postpartum depression is a major health problem, having a dangerous impact on postpartum mothers, their babies, and their families. The prevalence of depression in the Southeast Asia region is 27%, while in Indonesia the prevalence of depression is 3.7% and ranks second after India at 4.5%. This study aims to determine the Continuity of Care model for midwifery services with postpartum depression. The type of research used in this research is literature review research using 5 journals from the sources used in the form of journal search studies in electronic databases such as the Directory of Open Access Journals (DOAJ), ScienceDirect and EBSCO in full text form. So it can be concluded that a strong relationship between mothers and midwives who are known for providing continuous care, results in increased trust, more personal and loving care, and better sharing of information will reduce postpartum depression. To address knowledge gaps and methodological deficiencies in the existing literature, articles on postpartum depression in Asian countries need to further explore the role of physical, biological and cultural factors.
