Authors: Mei Lianpeng , Xiao Wensheng , Cui Junguo , Zhang Qingxue , Liu Zhanpeng
Published: November 2023

The pole–slot combination is an important factor affecting the cogging and electromagnetic characteristics of a permanent magnet synchronous motor. Taking a 95 kW direct-drive drilling permanent magnet synchronous motor (DPMSM) as an example, this paper presents an analytical model of the motor’s magnetic field based on the ideas of segmental discretization and magnetic vector potential, and considers a case in which the stator slot type is a closed slot. The Laplace or Poisson equations of each solution domain are solved using the separation of variables method, and the undetermined coefficients in the general solution are obtained by combining the boundary or interface conditions, thus completing the construction of the analytical model of the motor. The accuracy of this analytical model is verified with the finite element method (FEM). Based on the analytical model, the effects of the different pole–slot combinations on the electromagnetic performance, such as the air-gap flux density, back-EMF, cogging torque, output torque, etc., are investigated, and a reasonable choice of pole–slot combinations is made. The test results of the prototype are basically consistent with the predictions of the analytical model. The analytical model serves as an accurate and efficient calculation tool for the design of DPMSMs.
Divergent Effects of Topography on Soil Properties and Above-Ground Biomass in Nepal’s Mid-Hill Forests
Authors: Nepal Sandhya , KC Mohan , Pudasaini Nabaraj , Adhikari Hari
Published: November 2023

Various factors, including topography, climate, soil attributes, and vegetation composition, influence above-ground biomass productivity in forest ecosystems. Despite the success of community forestry in restoring degraded hill forests in Nepal, existing research offers limited insights into how topographic factors and plant species affect soil chemical properties and, in turn, influence above-ground biomass. This study investigates the interrelations between altitude, aspect, soil depth, and vegetation type on soil organic carbon (SOC), total nitrogen (TN), available phosphorus (P), available potassium (K), and soil pH. These soil metrics are further correlated with forestry indices, such as diameter at breast height (DBH), tree height (Ht), above-ground tree biomass (AGTB), basal area (BA), and above-ground total carbon (AGTC), in the mid-hill region of central Nepal. Our findings indicate that aspect had a significant influence on SOC (p < 0.001), TN (p < 0.001), P (p < 0.05), and pH (p < 0.001) levels. Soils in the northwest (NW) aspect exhibited higher levels of SOC and TN but lower levels of P and pH than those in the southeast (SE) aspect. Altitude did not significantly affect soil properties. Variations in SOC, TN, K, and pH were observed across different soil depths. Key forestry metrics like DBH, Ht, AGTB, and AGTC were notably higher at elevated altitudes and under the NW aspect. We also found that vegetation composition adds a layer of complexity to the relationship between aspect, soil properties, and above-ground biomass. The higher altitudes in the SE aspect are more conducive to above-ground biomass productivity, while the NW aspect is favorable for higher levels of SOC and TN in the soil. These variations could be due to differences in carbon deposition rates, plant compositions, soil microbial activities, and microclimatic conditions between the aspects. These findings highlight the need for holistic forest management approaches that consider topographic factors, soil depth, and plant species, offering practical implications for the region’s sustainable forest management and restoration efforts.
High-Resolution Real-Time Coastline Detection Using GNSS RTK, Optical, and Thermal SfM Photogrammetric Data in the Po River Delta, Italy
Authors: Fabris Massimo , Balin Mirco , Monego Michele
Published: November 2023

High-resolution coastline detection and monitoring are challenging on a global scale, especially in flat areas where natural events, sea level rise, and anthropic activities constantly modify the coastal environment. While the coastline related to the 0-level contour line can be extracted from accurate Digital Terrain Models (DTMs), the detection of the real-time, instantaneous coastline, especially at low tide, is a challenge that warrants further study and evaluation. In order to investigate an efficient combination of methods that allows to contribute to the knowledge in this field, this work uses topographic total station measurements, Global Navigation Satellite System Real-Time Kinematic (GNSS RTK) technique, and the Structure from Motion (SfM) approach (using a low-cost drone equipped with optical and thermal cameras). All the data were acquired at the beginning of 2022 and refer to the areas of Boccasette and Barricata, in the Po River Delta (Northeastern of Italy). The real-time coastline obtained from the GNSS data was validated using the topographic total station measurements; the correspondent polylines obtained from the photogrammetric data (using both automatic extraction and manual restitutions by visual inspection of orhophotos) were compared with the GNSS data to evaluate the performances of the different techniques. The results provided good agreement between the real-time coastlines obtained from different approaches. However, using the optical images, the accuracy was strictly connected with the radiometric changes in the photos and using thermal images, both manual and automatic polylines provided differences in the order of 1–2 m. Multi-temporal comparison of the 0-level coastline with those obtained from a LiDAR survey performed in 2018 provided the detection of the erosion and accretion areas in the period 2018–2022. The investigation on the two case studies showed a better accuracy of the GNSS RTK method in the real-time coastline detection. It can be considered as reliable ground-truth reference for the evaluation of the photogrammetric coastlines. While GNSS RTK proved to be more productive and efficient, optical and thermal SfM provided better results in terms of morphological completeness of the data.

Published: November 2023

In this paper, research was conducted on Deep Learning Wavefront Sensing (DLWS) neural networks using simulated atmospheric turbulence datasets, and a novel DLWS was proposed based on attention mechanisms and Convolutional Neural Networks (CNNs). The study encompassed both indoor experiments and kilometer-range laser transmission experiments employing DLWS. In terms of indoor experiments, data were collected and training was performed on the platform built by us. Subsequent comparative experiments with the Shack-Hartmann Wavefront Sensing (SHWS) method revealed that our DLWS model achieved accuracy on par with SHWS. For the kilometer-scale experiments, we directly applied the DLWS model obtained from the indoor platform, eliminating the need for new data collection or additional training. The DLWS predicts the wavefront from the beacon light PSF in real time and then uses it for aberration correction of the emitted laser. The results demonstrate a substantial improvement in the average peak intensity of the light spot at the target position after closed-loop correction, with a remarkable increase of 5.35 times compared to the open-loop configuration.
3D Object Detection Using Multiple-Frame Proposal Features Fusion
Authors: Huang Minyuan , Leung Henry , Hou Ming
Published: November 2023

Object detection is important in many applications, such as autonomous driving. While 2D images lack depth information and are sensitive to environmental conditions, 3D point clouds can provide accurate depth information and a more descriptive environment. However, sparsity is always a challenge in single-frame point cloud object detection. This paper introduces a two-stage proposal-based feature fusion method for object detection using multiple frames. The proposed method, called proposal features fusion (PFF), utilizes a cosine-similarity approach to associate proposals from multiple frames and employs an attention weighted fusion (AWF) module to merge features from these proposals. It allows for feature fusion specific to individual objects and offers lower computational complexity while achieving higher precision. The experimental results on the nuScenes dataset demonstrate the effectiveness of our approach, achieving an mAP of 46.7%, which is 1.3% higher than the state-of-the-art 3D object detection method.
Exploring the Femtosecond Filamentation Threshold in Liquid Media Using a Mach–Zehnder Interferometer
Authors: Zhang Yun , Xia Yu , Liang Canneng , Chen Anmin , Li Suyu , Jin Mingxing
Published: November 2023

We experimentally studied the supercontinuum induced by femtosecond filamentation in different liquid media. Using a Mach–Zehnder interferometer, we determined the relative filamentation thresholds (Pth) of these media. Research has shown that the value of the filamentation threshold is greater than that of Pcr (critical power for self-focusing), which can mainly be attributed to the strong dispersion effect. Changing the focal length of the focusing lens affects filamentation dynamics, thereby affecting the measured results regarding the filamentation threshold. With shorter focal lengths, the linear focusing (i.e., geometrical focusing) regime dominates, and the measured values of Pth for different liquid media are almost the same; as the focal length becomes larger, self-focusing starts to play a role, making the values of Pth for different media different from each other. This study presents an efficient method for investigating the femtosecond filamentation phenomenon in liquid media, helpful to provide further insights into the physical mechanism of supercontinuum generation via femtosecond filamentation in liquid media.

Published: November 2023

With the continuous advancement of technology, there is an increasing need for innovative solutions that can handle complex applications such as haptic communications, Internet of Things for smart cities, automation, and manufacturing. One technology that has received much attention is the phase reconfigurable metasurface for reconfigurable intelligent surfaces (RISs). The RIS demands low-power consumption, simple configuration, angular stability, and polarization insensitivity. The use of phase reconfigurable metasurfaces provides benefits such as low cost, low power consumption, and improved communication coverage and quality. This article introduces a reconfigurable combined-loop metasurface that can effectively manipulate phase reflection. This is achieved by incorporating four PIN diodes between two meta-atoms of a 2 × 2 periodic array within a single-layer metallic structure. By controlling the state of the PIN diodes, which can be switched into 16 different states, the metasurface can achieve various phase reflections. The proposed structure has validated a 32× 32 metasurface through numerical simulations and experiments that exhibit promising results, demonstrating its potential for use in 6G applications.

Authors: Ashby Jack , Lewis Martin , Sunderland Caroline , Barrett Laura A. , Morris John G.
Published: November 2023

(1) Background: The study examined the reliability (test–retest, intra- and inter-day) and validity of a portable 3D scanning method when quantifying human leg volume. (2) Methods: Fifteen males volunteered to participate (age, 24.6 ± 2.0 years; stature, 178.9 ± 4.5 cm; body mass, 77.4 ± 6.5 kg; mean ± standard deviation). The volume of the lower and upper legs was examined using a water displacement method (the criterion) and two consecutive 3D scans. Measurements were taken at baseline, 1 h post-baseline (intra-day) and 24 h post-baseline (inter-day). Reliability and validity of the 3D scanning method was assessed using Bland–Altman limits of agreement and Pearson’s product moment correlations. (3) Results: With respect to the test–retest reliability, the 3D scanning method had smaller systematic bias and narrower limits of agreement (±1%, and 3–5%, respectively) compared to the water displacement method (1–2% and 4–7%, respectively), when measuring lower and upper leg volume in humans. The correlation coefficients for all reliability comparisons (test–retest, intra-day, inter-day) would all be regarded as ‘very strong’ (all 0.94 or greater). (4) Conclusions: The study’s results suggest that a 3D scanning method is a reliable and valid method to quantify leg volume.

Published: November 2023

Electric scooters are quickly becoming a popular form of mobility in many cities around the world, which has led to a surge in safety incidents. Moreover, electric scooters are not equipped with safety devices for riders, which can lead to serious accidents. In this study, a footrest, data-collection module, and accelerometer module for electric scooters were developed to prevent various accidents caused by the rapid increase in the use of electric scooters. In the experiment, the boarding data of the electric-scooter riders were collected from the footrest and data-collection module. Moreover, the driving data of the electric scooters for different road types were collected with the accelerometer module. We then trained two artificial intelligence (AI) models based on convolutional neural networks (CNNs) for different types of data. When we considered the learning accuracy and mean square error (MSE), which are performance indicators of the ability of the trained AI models to discriminate data, for each AI model, the learning accuracy converged to 100% and the MSE converged to 0. Further, this study is expected to help reduce the accident rate of electric scooters by resolving the causes of frequent accidents involving electric scooters around the world.
Hand Selection in Dribbling Phases: An Analysis of Non-Dominant Hand Usage and Dribble Change in Basketball
Authors: Onodera Keisuke , Takeda Masaki
Published: November 2023

This study investigates the influence of different dribbling phases on hand selection among basketball players across various categories. A total of 33 guard players, including 11 from high school, college, and NBA teams each, were observed. Video data analysis was utilized to determine the frequency of players using their dominant hands (DHs) and non-dominant hands (NDHs) during in-game dribbling phases. The dribbling phases were classified into three categories: First (the initiation of the dribble), Middle (during the dribble but not in First and Last), and Last (the completion of the dribble). Percentage, means, and standard deviations were computed for each category within the First, Middle, and Last measurements. A two-factor analysis of variance (ANOVA) was conducted, considering player category and dribbling phase as factors. The ANOVA revealed significant main effects of player category (p < 0.01) and dribbling phase (p < 0.01). Post hoc multiple comparisons using Holm’s method indicated that, in the First phase, players exhibited a 6.5% higher preference for using their NDHs (43.4 ± 11.9%) compared to the Middle phase (36.9 ± 13.9%) (p < 0.05). Similarly, in the Last phase, players displayed a 5.3% greater inclination towards using their NDHs (42.2 ± 11.7%) compared to the Middle phase (p < 0.05). These findings provide quantitative evidence that the specific dribbling phase influences hand selection during gameplay. The implications of these results are significant for basketball coaches, as they can design targeted training programs and drills that simulate game scenarios and encourage NDH usage. By understanding the factors influencing hand choice, players can enhance their versatility and adaptability on the court. Furthermore, these findings contribute to player performance, skill development, and strategic decision making in dribbling phases.

Authors: Khoa Vo Dang , Chinda Thanwadee
Published: November 2023

In the turbulent construction market, the knowledge management process (KMP) is one of the most valuable tools of sustainability to help construction companies deal with dynamic changes and enhance their construction competitiveness (CC). To effectively utilize KMP in construction, this study aims to explore the interrelationships between key KMP factors and their influences on the CC, utilizing the structural equation modeling (SEM) approach. The objectives include extracting key KMP factors necessary for the CC enhancement, identifying direct and indirect relationships between the KMP and CC factors, and developing a self-assessment form to assist construction companies in evaluating their KMP performance and planning for long-term improvement. The results show that the five key KMP factors, namely knowledge utilization (KU), knowledge dissemination (KD), knowledge responsiveness (KR), knowledge storage (KS), and knowledge acquisition (KA), have direct and indirect effects on CC and that the feedback of CC is sent back to KMP factors for continuous improvement. The KU factor is crucial for short-term improvement. Construction companies should utilize stakeholders’ current practices and experiences to solve problems, conclude lessons learned, and pinpoint practices for future uses. The KS factor, on the other hand, should be emphasized for long-term plans to enhance KMP implementation and CC achievements. A long-term investment plan should be initiated in the database system to properly and effectively implement digital transformation in the 4.0 Era. The self-assessment form developed from the study results assists construction companies in assessing their KMP implementation and planning for sustainable development.

Authors: Long Su Xian , Khoo Shin Yee , Ong Zhi Chao , Soong Ming Foong , Huang Yu-Hsi
Published: November 2023

In recent years, much research has been carried out to enhance the efficiency of the piezoelectric energy harvester (PEH). This study focuses on the performance of the compressive Hull PEH under impact forces, which simulates real-world scenarios, such as foot strikes or vehicular wheel excitations, more accurately compared to harmonic forces. The experimental results prove the performance of the Hull PEH with less than 5.2% of deviation compared to finite element analysis outcomes under impact forces between 10 N and 1 kN. The Hull PEH more substantially amplified the input force and compressed the piezoelectric material, which was Lead Zirconate Titanate (PZT). Consequently, it amplified the voltage output of a standalone PZT up to 16.9 times under a similar boundary condition. A maximum peak power output of 7.16 W was produced across 50 kΩ of optimum load resistance under 1 kN of impact force, which surpassed the benchmark Cymbal PEH by 37.68 times. Furthermore, it demonstrated a higher energy conversion efficiency of 84.38% under the impact force compared to the harmonic force. This research conclusively proves that the Hull PEH has superior performance in terms of voltage output, power output, loading capacity, and efficiency, making it a promising technology for impact loading applications to generate green energy.

New technologies have improved the efficiency and sustainability of psychosocial research. However, online assessment tools may differ from traditional paper-based ones in different domains. This study aims to provide an updated perspective of the online assessment advantages of a psychosocial platform called MenPas 1.0. A literature review was conducted, choosing validated questionnaire studies located in the MenPas 1.0 platform, specifically, motivation and hypnosis questionnaires. A total of five studies showing the psychometric properties of psychosocial evaluation tools were analysed and compared with their previous paper-based studies. In addition, internet impact over the last 20 years was analysed according to gender, age, nationality, and employment status. Finally, a conclusion was drawn on the impact of these tools on sustainability. The results showed that online studies have a higher number of participants (5866 users in 5 studies versus 5623 participants in 11 studies) and higher reliability rates than those of previous paper-based ones. A decrease in the social gap over the years was also found and the contribution of online tools to sustainability was discussed. This study could show the importance of the analysis of psychometric properties in online tools, the need for further research, and encourage their use in psychosocial assessment.

Authors: Gabr Mohamed Elsayed , El-Rawy Mustafa , Al-Arifi Nassir , Zijl Wouter , Abdalla Fathy
Published: November 2023

In this study, a decentralized new sewage water treatment system is suggested and designed in Ar Riyadh, Saudi Arabia, to safeguard the environment and reuse treated water for irrigation purposes. The system consists of a primary treatment (septic tank), a subsurface horizontal flow constructed wetland (HSSF-CW), and a storage ground tank. The research methodology employed in this study is (i) to define the wastewater characteristics, where air temperature in winter is 18.6 °C, the wastewater flow per person (q) is 150 L/d, demonstrating an inlet design discharge of 300 m3/d, the influent pollutant concentrations for biological oxygen demand (BOD), total suspended solids (TSS), chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP), and fecal coliforms (FC) are 350, 1000, 700, 50, 12 mg/L, and 106 CFU/100 mL, respectively; (ii) to design the septic tank based on a retention time of two days and a surfacing load rate of 1.5 m/d; (iii) the P-k-C* model was used to determine the HSSF-CW surface area based on reed beds of Phragmites australis (common reed) and papyrus plants, where the removal rate was constant at 20 °C for BOD, TP, and FC in the effluent concentrations not exceeding 20 mg/L, 3.0 mg/L, and 2000 CFU/100 mL in order to satisfy Saudi Arabia’s wastewater reuse requirements; and (iv) to design the clean water tank for a hydraulic retention time of 10 h. The results demonstrate that the removing pollutants design area is 1872 m2 divided into nine cells, each of width 8 m and length 26 m, with a hydraulic loading rate (LR) of 0.16 m/d and a hydraulic resident time (RT) of 1.1 d. The effluent pollutant concentrations for the BOD, FC, TN, and TP were 245 mg/L, 103 CFU/100 mL, 35, and 8.5 mg/L, respectively. The wastewater treatment system total removal efficiencies for BOD, TN, TP, and FC were estimated to be 91.8, 70, 57, and 98.5%, respectively. Design curves were developed to ease the design steps. The HSSF-CW is a green wastewater treatment technology that offers greatly decreased investment costs, and service particularly for small-scale applications up to 6000 persons.

Authors: Zhu Tianyuan , Zhang Shuming , Wang Yubo , Wang Cuiping , Wang Haowei
Published: November 2023

Different types of ecosystems form a complex community of life. Hence, ecosystem protection and restoration should not focus solely on a single ecosystem. Ecosystem health assessments should consider the integrity and systematicity of interrelated ecosystems to inform rational environmental planning and management. In this study, the key characteristic indicators of major ecosystems (mountain, water, forest, and cropland) and ecosystem service capacity indicators in Anxi County, China, were selected to construct an integrated assessment system of ecosystem health that led to integrated ecosystem restoration pathways that addressed the county’s ecological problems. The results revealed that ecosystem health was higher in the western and lower in the eastern parts of the county. Throughout the county, “medium” and “poor” ecosystem health levels predominated, revealing that overall ecosystem sustainability was weak. Ecosystem restoration programmes should be tailored to each health level. Where there was “excellent” and “good” ecosystem health ratings, those healthy ecosystem functions should be strengthened and maintained. In the “medium” health areas, the control and prevention of ecological problems should be strengthened. “Poor” health areas require immediate integrated ecological restoration projects that ensure the connectivity and coordination of restoration tasks in fragile ecosystems. This then will enhance holistic ecosystem stability and sustainability.
Angular-Momentum Modes in a Bosonic Condensate Trapped in the Inverse-Square Potential
Authors: Sakaguchi Hidetsugu , Malomed Boris A.
Published: November 2023

In the mean-field approximation, the well-known effect of the critical quantum collapse in a 3D gas of particles pulled to the center by potential U(r)=−U0/2r2 is suppressed by repulsive inter-particle interactions, which create the otherwise non-existing s-wave ground state. Here, we address excited bound states carrying angular momentum, with the orbital and magnetic quantum numbers l and m. They exist above a threshold value of the potential’s strength, U0>l(l+1). The sectoral, tesseral, and zonal modes, which correspond to m=l, 0<m<l, and m=0, respectively, are found in an approximate analytical form for relatively small values of U0−l(l+1). Explicit results are produced for the p- and d-wave states, with l=1 and 2, respectively. In the general form, the bound states are obtained numerically, confirming the accuracy of the analytical approximation.
Burden of Renal Dysfunction and Neurologic Complications in Hospitalized Pediatric Heart Failure Unrelated to Congenital Heart Disease: A Multicenter Study
Authors: Das Bibhuti , Godown Justin , Deshpande Shriprasad R.
Published: November 2023

Objectives: Limited data are available on renal dysfunction and neurologic complications in heart failure in children, when the heart failure is not related to congenital heart disease (CHD) or cardiac surgery. This study used a multi-center database to describe pediatric heart failure (pHF)-related renal dysfunction, neurological complications, and outcomes in non-CHD patients. Methods: The Pediatric Health Information System (PHIS) database between 2004 and 2020 was used to analyze the prevalence of renal dysfunction and neurologic complications associated with pHF hospitalizations and their impact on outcomes. Results: Of the 5515 hospitalizations included in the study, renal dysfunction was identified in 1239 (22.5%), and neurologic dysfunction was diagnosed in 539 (9.8%). The diagnosis of renal or neurologic complications was associated with significantly higher use of ICU therapies, including mechanical ventilation, parenteral nutrition, and mechanical circulatory support. Patients with significant renal dysfunction were likely to receive kidney transplants in 3.1% of the cases. Neurologic complications were higher in patients with pHF who underwent heart transplantation (21.3% vs. 7.8%, p < 0.001). Patients with renal dysfunction and neurologic complications had significantly higher mortality rates than those without renal dysfunction (11.7% vs. 4.3%, p < 0.001) and neurologic complications (18.4% vs. 4.6%, p < 0.001). Conclusions: Renal dysfunction and neurologic complications are common, resulting in significantly higher utilization of ICU therapies and mortality rates during non-CHD-related pHF hospitalization. Neurologic complications associated with hospitalization for pHF are associated with a significantly higher mortality, which has been underemphasized in the literature. This study assesses the burden of these morbidities and highlights the importance of monitoring and managing renal and neurologic complications in pHF to improve outcomes.
Screening Drugs for Broad-Spectrum, Host-Directed Antiviral Activity: Lessons from the Development of Probenecid for COVID-19
Authors: Tripp Ralph A. , Martin David E.
Published: November 2023

In the early stages of drug discovery, researchers develop assays that are compatible with high throughput screening (HTS) and structure activity relationship (SAR) measurements. These assays are designed to evaluate the effectiveness of new and known molecular entities, typically targeting specific features within the virus. Drugs that inhibit virus replication by inhibiting a host gene or pathway are often missed because the goal is to identify active antiviral agents against known viral targets. Screening efforts should be sufficiently robust to identify all potential targets regardless of the antiviral mechanism to avoid misleading conclusions.

The declaration of the conclusion of the COVID-19 pandemic notwithstanding, coronavirus remains prevalent in circulation, and the potential emergence of novel variants of concern introduces the possibility of new outbreaks. Moreover, it is not clear how quickly and to what extent the effectiveness of vaccination will decline as the virus continues to mutate. One possible solution to combat the rapidly mutating coronavirus is the creation of safe vaccine platforms that can be rapidly adapted to deliver new, specific antigens in response to viral mutations. Recombinant probiotic microorganisms that can produce viral antigens by inserting specific viral DNA fragments into their genome show promise as a platform and vector for mucosal vaccine antigen delivery. The authors of this study have developed a convenient and universal technique for inserting the DNA sequences of pathogenic bacteria and viruses into the gene that encodes the pili protein of the probiotic strain E. faecium L3. The paper presents data on the immunogenic properties of two E. faecium L3 vaccine strains, which produce two different fragments of the coronavirus S1 protein, and provides an assessment of the protective efficacy of these oral vaccines against coronavirus infection in Syrian hamsters.

This study investigates the natural hydrogeochemical mechanisms that govern groundwater chemistry at the margins of the Silao-Romita, Valle de León, and La Muralla aquifers in Mexico’s “Bajío Guanajuatense”. The wells of the La Muralla aquifer have temperatures ranging from 25 to 45 °C, while in the valleys, the temperatures range from 25 to 29 °C. In the Sierra de Guanajuato recharge zone, the thermal spring registers 95 °C. High Na concentrations (125 to 178 mg/L) are measured due to thermalism. One sample includes 316 mg/L of SO4, which is related to a potential gypsum zone. Three hydrogeochemical facies are identified (Ca-Mg HCO3, Na-Ca-HCO3, and Na-HCO3). The hydrogeochemical characterization and processes imply hydraulic linkage via regional thermal flows enhanced by faults and the mixing of local flow waters with intermediate flows. The isotopic results indicate that part of the groundwater volume has been exposed to local evaporation processes due to the presence of surface water bodies and irrigation returns. The highest isotopic enrichment is observed near or in the recharge regions. In contrast, the most depleted zones are in the valleys, where there is a more significant interaction with the rock and a longer residence time, implying a mixture of local water flows with deeper or intermediate flows, which, when combined with water geochemistry, indicates a connection between the aquifers studied. The Kruskal–Wallis variance tests, used to compare the differences between aquifers, show that the Valle de León aquifer has more significant differences with respect to the Silao-Romita and La Muralla aquifers. This study’s findings are essential for one of central Mexico’s most populous and economically active areas.

Friendship: The ‘Achilles Heel’ of European Youth Work Policy
Authors: Ord Jon , Jeffs Tony
Published: November 2023

This paper analyses the historical development of friendship in youth work in the UK and more recent studies of the impact of youth work in both the UK and in the wider European context to argue that European youth work has failed to acknowledge this important aspect of practice. During youth work’s initial 150 years in the UK three concepts resided at the heart of the enterprise: (a) the ‘club’; (b) ‘membership’ and (c) ‘friendship’. Friendship eclipsed the others for they grew out of the friendships formed between workers and young people, and the young people themselves. Practitioners during this era expected to offer unconditional friendship to members, and to teach them the arts of acquiring and sustaining friendships via the modelling of virtuous behaviour.

Purpose - This article explores academic job crafting's significant conditions (antecedents and consequences). The impact of encouraging learning environments and the leadership that fortifies learning was studied. Knowledge management and job crafting are closely related in their ability to empower employees and enhance organizational effectiveness. Design/methodology/approach –217 academics serving in a Jordanian University, in Jordan, took part in this study. Statistical parameters endorsed the significant impact of two learning organization building blocks on job crafting. Findings - It was shown that supportive learning environments and leadership reinforces learning; and positively impacts job crafting, which consequently reflects upon job satisfaction levels among academics. The results imply that strategies conducive to learning provide the most rewarding approach to enhancing academic job crafting and job satisfaction.  Originality/value – To the authors’ knowledge, no prior study has examined job crafting and linked it to the study dimensions within the Arab context generally and particularly in the academic field. We propose this model as a system crafting theory and end our research with suggestions for further research on these issues.
