We perform an angular analysis of the B→K*e+e− decay for the dielectron mass squared, q2, range of 0.0008–1.1200  GeV2/c4 using the full Belle dataset in the K*0→K+π− and K*+→KS0π+ channels, incorporating new methods of electron identification to improve the statistical power of the dataset. This analysis is sensitive to contributions from right-handed currents from physics beyond the Standard Model by constraining the Wilson coefficients C7(′). We perform a fit to the B→K*e+e− differential decay rate and measure the imaginary component of the transversality amplitude to be ATIm=−1.27±0.52±0.12, and the K* transverse asymmetry to be AT(2)=0.52±0.53±0.11, with FL and ATRe fixed to the Standard Model values. The resulting constraints on the value of C7′ are consistent with the Standard Model within a 2σ confidence interval.

Effective action and black hole solutions in asymptotically safe quantum gravity
Authors: Pawlowski Jan M. , Tränkle Jan
Published: October 2024

We derive the quantum effective action and the respective quantum equations of motion from multi-graviton correlation functions in asymptotically safe quantum gravity. The fully momentum-dependent couplings of three- and four-graviton scatterings are computed within the functional renormalization group approach and the effective action is reconstructed from these vertices. The resulting quantum equations of motion are solved numerically for quantum black hole geometries. Importantly, the black hole solutions show signatures of quantum gravity outside the classical horizon, which manifest in the behavior of the temporal and radial components of the metric. Three different types of solutions with distinct causal structures are identified and the phase structure of the solution space is investigated.

Fermi surface and Lifshitz transitions of a ferromagnetic superconductor under external magnetic fields
Authors: Leenen R. , Aoki D. , Knebel G. , Pourret A. , McCollam A.
Published: October 2024

Lifshitz transitions are being increasingly recognized as significant in a wide variety of strongly correlated and topological materials, and understanding the origin and influence of Lifshitz transitions is leading to deeper understanding of key aspects of magnetic, transport, or quantum critical behavior. In the ferromagnetic superconductor UCoGe, a magnetic field applied along the c axis has been shown to induce a series of anomalies in both transport and thermopower that may be caused by Lifshitz transitions. The need to understand the subtleties of the relationship between magnetism, superconductivity and a heavy-electron Fermi surface in the ferromagnetic superconductors makes it important to explore if and why a series of magnetic-field-induced Lifshitz transitions occurs in UCoGe. Here we report magnetic susceptibility measurements of UCoGe, performed at temperatures down to 45 mK and magnetic fields (μ0H||c) up to 30 T. We observe a series of clearly defined features in the susceptibility, and multiple sets of strongly field-dependent de Haas-van Alphen oscillations, from which we extract detailed field dependence of the quasiparticle properties. We complement our experimental results with density functional theory band structure calculations, and include a simple model of the influence of magnetic field on the calculated Fermi surface. By comparing experimental and calculated results, we determine the likely shape of the Fermi surface and identify candidate Lifshitz transitions that could correspond to two of the features in susceptibility. We connect these results to the development of magnetization in the system.

To control and measure the state of a quantum system, it must necessarily be coupled to external degrees of freedom. This inevitably leads to spontaneous emission via the Purcell effect, photon-induced dephasing from measurement backaction, and errors caused by unwanted interactions with nearby quantum systems. To tackle this fundamental challenge, we make use of the design flexibility of superconducting quantum circuits to form a multimode element—an artificial molecule—with symmetry-protected modes. The proposed circuit consists of three superconducting islands coupled to a central island via Josephson junctions. It exhibits two essential nonlinear modes, one of which is flux insensitive and used as the protected qubit mode. The second mode is flux tunable and serves via a cross-Kerr-type coupling as a mediator to control the dispersive coupling of the qubit mode to the readout resonator. We demonstrate the Purcell protection of the qubit mode by measuring relaxation times that are independent of the mediated dispersive coupling. We show that the coherence of the qubit is not limited by photon-induced dephasing when detuning the mediator mode from the readout resonator and thereby reducing the dispersive coupling. The resulting highly protected qubit, which we refer to as P-mon, with tunable interactions may serve as a basic building block of a scalable quantum processor architecture, in which qubit decoherence is strongly suppressed.

Periodic diffraction from an aperiodic monohedral tiling – the Spectre tiling. Addendum
Authors: Kaplan Craig S. , O'Keeffe Michael , Treacy Michael M. J.
Published: October 2024

This article describes the diffraction pattern (2-periodic Fourier transform) from the vertices of a large patch of the recently discovered `Spectre' tiling – a strictly chiral aperiodic monotile. It was reported recently that the diffraction pattern of the related weakly chiral aperiodic `Hat' monotile was 2-periodic with chiral plane-group symmetry p6 [Kaplan et al. (2024). Acta Cryst. A80, 72–78]. The diffraction periodicity arises because the Hat tiling is a systematic aperiodic deletion of vertices from the 2-periodic hexagonal mta tiling. Despite the similarity of the Hat and Spectre tilings, the Spectre tiling is not aligned with a 2-periodic lattice, and its diffraction pattern is non-periodic with chiral point symmetry 6 about the origin.

DBA as an enabler of future management practice – case study insights and reflections from recent graduates
Authors: Kearney Arthur , Harrington Denis , Dempsey David , Collings David
Published: October 2024

Purpose

The purpose of the study is to explore a Doctorate in Business Administration (DBA) programme in the context of a small emerging Irish university as an enabler for future management practice development.

Design/methodology/approach

The research comprises a literature review and a single case study focused on a single DBA graduate of a DBA programme embedded in a new technological Irish university.

Findings

Findings indicate that the DBA supports a unique form of managerial learning supportive of the development of future management practice in graduates. Specifically, such managerial learning emerges from the embracement of differences by both faculty and students; guidance by faculty in opening students to uncertainty and unknowing and in supporting students towards becoming architects of socio-technical organisational change. Ultimately, the DBA graduate is not viewed as leaving the programme, with novel management practices that are time-bound, rather they are imbued with a learning potential supportive of continual management practice development into the future. Theoretically, the authors extend studies that indicate the potential of the DBA as a mechanism for management practice development, indicating the role of managerial learning in context.

Research limitations/implications

The research is limited to a single case study of a DBA programme embedded in a new technological Irish university and draws from the perspective of one key informant graduate. Hence, future research into how managerial learning impacts new management practice development in the context of other universities is encouraged.

Practical implications

The central role of managerial learning promoted in the DBA within this new technological university indicates two practical implications of the research. First, both organisations and students considering DBA education as a means of developing future management practices are encouraged to contemplate such education through the lens of managerial learning. It is anticipated that such contemplation will improve preparedness. Second, business schools are encouraged to contemplate improving their programmes through the managerial learning lens, with such improvement activating potential in marketing the DBA to both students and organisations.

Originality/value

Theoretically the authors extend existing studies that indicate the potential of the DBA as a mechanism for management practice development. Specifically the role of contextual managerial learning is articulated, and is argued to support a management practice development capable of continual transformation.
Research on wind turbines preventive maintenance strategies based on reliability and cost-effectiveness ratio
Authors: Li Jian Hua , Jia Shilin , Ren Lina , Li Xueliang
Published: October 2024

Purpose

The purpose of this study is to optimize the operational efficiency of the entire system by developing a reasonable maintenance strategy for wind turbines that improves component reliability and safety while reducing maintenance costs.

Design/methodology/approach

A hybrid incomplete preventive maintenance (PM) model based on boundary intensity process is established to give dynamic PM intervals for wind turbines using an iterative method with reliability as a constraint; the selection method of PM and replacement is given based on the cost-effectiveness ratio, which in turn determines the optimal number of PM for wind turbines.

Findings

The reliability is used to obtain the components’ maintenance cycle, and the cost-effectiveness ratio is used to select the number of maintenance times, thus, getting the optimal maintenance strategy. The validity of this paper’s method is verified by arithmetic cases, which provides a new method for formulating a reasonable PM strategy for wind turbines.

Practical implications

The wind turbine preventive maintenance strategy for Boundary intensity process proposed in this paper can scientifically formulate the maintenance strategy, optimize the cost-effectiveness per unit of time of the wind power generation system, and solve the problems of difficulty in formulating a reasonable maintenance strategy for the wind turbine components and high operation and maintenance costs.

Originality/value

In this paper, the authors describe the failure pattern by a Boundary intensity process, establish a hybrid incomplete PM model by introducing a failure intensity increment factor and an age reduction factor and establish a maintenance strategy optimization model with comprehensive consideration of reliability and cost-effectiveness ratio. Finally, the validity of the model in this paper is verified by arithmetic case analysis.

EMSA-IK: a real-time evolutionary multi-objective semi-analytical inverse kinematics algorithm for redundant manipulators
Authors: Chen Zhaoyang , Min Kang , Fan Xinyang , Tu Baoxu , Ni Fenglei , Liu Hong
Published: October 2024

Purpose

This paper aims to propose a real-time evolutionary multi-objective semi-analytical inverse kinematics (IK) algorithm (EMSA-IK) for solving the multi-objective IK of redundant manipulators.

Design/methodology/approach

Within EMSA-IK, the parameterization method is applied to reduce the number of optimization variables of the evolutionary algorithm and calculate semi-analytical solutions that meet high target pose accuracy. The original evolutionary algorithm is improved with the proposed adaptive search sub-space strategy so that the improved evolutionary algorithm can be used to efficiently perform global search within the parametric joint space to obtain the global optimal parametric joint angles that satisfy multi-objective constraints.

Findings

Ablation experiments show the effectiveness of the improved strategy used for evolutionary algorithms. Comparative experiments on different manipulators demonstrate the advantages of EMSA-IK in terms of generalizability and balancing multiple objectives, for example, motion continuity, joint limits and obstacle avoidance. Real-world experiments further validate the effectiveness of the proposed algorithm for real-time application.

Originality/value

The semi-analytical IK solution that simultaneously satisfies high target pose accuracy and multi-objective constraints can be obtained in real time. Compared to existing semi-analytical IK algorithms, the proposed algorithm achieves obstacle avoidance for the first time. The proposed algorithm demonstrates superior generalizability, applicable to not only redundant manipulators with revolute joints but also those with prismatic joints.
Pilot study of an anti-racist professional development: effects on educators’ multicultural attitudes and efficacy
Authors: Stoffers Melissa , Barnes Tia Navelene , Strickland Lauren , Jung Joanne , Branch Kira , Perry Danika , Hatchimonji Danielle
Published: October 2024

Purpose

This study aims to understand the impact of a pilot of the actions against racism (AAR) intervention, aimed at enhancing educators’ multicultural efficacy and attitudes in a mid-Atlantic K-8 charter school.

Design/methodology/approach

AAR included eight sessions delivered over one school year. Experienced facilitators led these sessions, focusing on combating racism, prejudice and discrimination. Of the 84 school staff, 56 completed a baseline survey and 33 completed a postintervention survey.

Findings

Paired sample t-tests revealed a significant increase in multicultural attitudes, t(29) = 2.55, p = 0.016, whereas the increase in multicultural efficacy was not significant, t(28) = 1.93, p = 0.063. The authors examined cultural and emotional intelligence as moderators of the intervention’s impact. Higher baseline cognitive reappraisal scores (an indicator of emotional intelligence) were linked to a larger increase in multicultural efficacy from pre- to postintervention, B = −0.59, t (27) = −2.20, p = 0.037. The number of sessions attended was unrelated to the intervention’s impact.

Research limitations/implications

This study was a single-site, uncontrolled pilot of AAR with a small sample size. Further research in additional settings with appropriately powered samples is needed to validate these results and extend findings to examine the impact of AAR on the student experience.

Originality/value

The study demonstrates the promising potential of AAR in improving teachers' multicultural attitudes and efficacy. Exploratory findings highlight the role of cognitive reappraisal in enhancing multicultural efficacy, contributing valuable insights for designing effective teacher training programs. This research supports the implementation of critical, identity-centered and asset-based pedagogies in education.

Technology acceptance of balcony solar systems in Hungary – exploring influencing factors in a late-adopter country
Authors: Molnár László , Szép Tekla
Published: October 2024

Purpose

Balcony solar panels are popular and widespread in most EU Member States, except in Hungary, where their use is currently banned. However, the lifting of this strict ban is expected to be approved in the near future. The aim of this research is to investigate which factors influence residents’ intention to use balcony solar panels in Hungary and how strong these impacts are.

Design/methodology/approach

Unified theory of acceptance and use of technology 2 (UTAUT2) is applied to predict which factors may influence residents’ behavioral intention to use this technology. Six components are tested: performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation and price value. Data were gathered in Hungary in 2023 using an online survey. A quota sampling method was employed during the data-collection process.

Findings

Our results confirm the importance of all components except effort expectancy. In addition to the economic benefits that can be achieved, citizens consider energy independence and a sense of freedom to be important in the adoption of such systems.

Research limitations/implications

Despite the large share of positive responses (expressed intention) that is identified, a gap between intention and action can be expected.

Practical implications

To increase the rate of acceptance, transparent regulation, simplified administration and the application of nudges may be crucially important. However, the widespread use of balcony solar systems is hindered by the lack of a modern, energy-efficient building stock, emphasizing the urgency of deep renovation in the Hungarian household sector.

Originality/value

This research is the first to use the UTAUT2 model to analyze the technology acceptance of balcony solar systems in a late-adopter country.
What were the different roles women played during the American Revolution?
Authors: Waring Scott M. , Forsyth Samantha
Published: October 2024

Purpose

Through the approach presented here, the authors created an investigation, utilizing the SOURCES Framework for Teaching with Primary and Secondary Sources, to allow their students to better understand that many people, specifically many dynamic women from diverse backgrounds, played vital roles, individually and collectively, in the fight for independence and, ultimately, the creation of the United States of America.

Design/methodology/approach

The SOURCES Framework for Teaching with Primary and Secondary Sources is a framework that was developed to scaffold the learning process for students to replicate that which is done by historians. This approach allows students in the classroom, in a structured manner, to analyze primary and secondary sources in authentic and engaging ways in pursuit of answers to an essential question, and others of interest to each student, regarding historical events, controversy, etc. This process empowers students to think critically, weigh various perspectives and accounts and to develop their own evidence-based response to an essential question that is central to guiding and driving inquiry.

Findings

Through the analysis of primary and secondary sources related to women’s roles and efforts during the American Revolution, students were able to develop their own evidence-based narratives to answer the essential question of “What were the different roles women played during the American Revolution?”

Originality/value

The authors of the manuscript outline a unique approach to teaching students about the importance of women to the independence efforts in the United States during the late 18th century. Teachers of all grade levels and various content can modify and adapt the methods and resources presented here.
Can human lean practices affect business performance? Evidence from Zimbabwe service industries
Authors: Machingura Tinotenda , Adetunji Olufemi , Muyavu Ashleigh Tatenda , Maware Catherine
Published: October 2024

Purpose

This research seeks to explore the interrelationships between human lean practices (HLP) and their impact on the business performance of service industries.

Design/methodology/approach

A questionnaire was used to collect data from the service industries in Zimbabwe, and 260 valid responses were obtained. The questionnaire was analyzed using structural equation modeling (SEM) in SmartPLS.

Findings

Both the managerial human lean practices (MHLP) and employee human lean practices (EHLP) were found to positively impact business performance. Also, the MHLP had a positive relationship with EHLP.

Research limitations/implications

The research focused on Zimbabwe’s service industry; hence, the results may not be readily adopted by other industries and countries without further investigations.

Practical implications

The improvement in business performance is centered on the activities of humans, both the employees and managers. Therefore, organizations should invest more in human resources to enhance their performance.

Originality/value

Lean manufacturing (LM) is well known for its adoption in the manufacturing industry; thus, extending it to other sectors requires further research. Although a few studies have investigated the effect of adopting Lean in the service sector, they did not explore the relationship between MHLP and EHLP and the importance of such a relationship toward improved business performance.

These insights provide a foundation for tourism stakeholders to tailor strategies such as environmental education programs and supportive policies to promote sustainable tourism practices among Vietnamese tourists effectively.
Measuring the intensity of challenges and problems of small-scale entrepreneurs in Uttarakhand, India
Authors: Joshi Kamal , Mishra Manoj Kumar , Jamal Mohammad , Janotra Joney
Published: October 2024

Purpose

This study aims to understand the relative intensity of the challenges and problems faced by small-scale entrepreneurs in Uttarakhand.

Design/methodology/approach

A survey methodology was used for this study. The judgement sampling method was used to select the sample for this study. The data were collected from 240 small-scale entrepreneurs using a self-structured questionnaire. Descriptive statistics, principal component analysis and confirmatory factor analysis were used to analyse the data.

Findings

The survey found that marketing, finance, taxation, human resource and government support–related problems are the major problems of small-scale entrepreneurs in the state.

Research limitations/implications

This study was conducted in both rural and urban areas, but due to the unreachability of rural entrepreneurs, the representation of rural entrepreneurs is less, so the findings are more inclined towards urban entrepreneurs.

Maternal Lipids in Pregnancy and Later Life Dyslipidemia: The POUCHmoms Longitudinal Cohort Study
Authors: Dunietz Galit Levi , Holzman Claudia , Lyu Xiru , Tauman Riva , Catov Janet M.
Published: October 2024

Objective

Maternal lipid levels increase in normal pregnancies. Here, we examine whether pregnancies with the highest total cholesterol, low‐density lipoprotein (LDL) or triglyceride levels or the lowest high‐density lipoprotein (HDL) levels predict future dyslipidemia post‐pregnancy.

Design

Longitudinal cohort study.

Setting

Five communities in Michigan, USA.

Sample

Pregnant women (n = 649) with blood lipid levels measured at mid‐pregnancy in the Pregnancy Outcomes and Community Health (POUCH) Study and at the POUCHmoms Study follow‐up, 7–15 years later.

Methods

Maternal mid‐pregnancy lipid levels were defined as ‘high’ (upper quartile of triglycerides ≥ 216 mg/dL, LDL ≥ 145 mg/dL and total cholesterol ≥ 256 mg/dL) or ‘low’ (lower quartile, HDL < 58 mg/dL) using whole sample lipid distributions. At follow‐up, dyslipidemia was classified by the clinical cutoffs of triglycerides and total cholesterol ≥ 200 mg/dL, LDL ≥ 130 mg/dL and HDL < 50 mg/dL. Weighted regression models estimated the risk of dyslipidemia at follow‐up in relation to pregnancy lipid levels, adjusted for baseline confounders.

Main Outcome Measure

Dyslipidemia later in life.

Results

Mid‐pregnancy triglycerides, LDL, and total cholesterol levels at the upper quartile were associated with at least threefold increase in the risk of abnormal triglycerides, LDL and total cholesterol levels later in life. Women with low mid‐pregnancy HDL levels had just over a twofold increased risk of abnormally low HDL levels at follow‐up. These associations persisted following adjustment for covariates, i.e. demographics, lifestyle, and years of follow‐up.

Conclusions

Higher mid‐pregnancy LDL, total cholesterol and triglycerides and lower levels of HDL may signal future dyslipidemia risk and the need for closer lipid monitoring to ensure timely interventions that can attenuate cardiovascular disease risk.

Objective

To determine the proportion of women presenting to EDs across a regional health district, with early pregnancy bleeding, who received appropriate care.

Methods

Retrospective cohort review of linked data from five data sets: ED, pathology, radiology, costs and non‐admitted/outpatient. Data collected from five EDs between January 2011 and December 2020, across one health district in NSW, Australia, with 150 000 annual ED presentations. Management received by women of reproductive age, with early pregnancy (<20 weeks gestation) bleeding was compared to seven indicators for recommended care. Indicators included blood tests, psychosocial support, administration of Rhesus D immunoglobulin and US. Indicators were determined by a systematic analysis of published primary research, expert consensus clinical practice guidelines and literature reviews on initial assessment, intervention and diagnostics for women with early pregnancy bleeding.

Results

There was no evidence of almost one third of women (n = 3661, 29.4%) receiving any indicators and 54 (0.4%) received five or more indicators of appropriate care. Presentations to rural facility had the lowest number and proportion of indicators being performed (n = 603, 58.0% for no indicators). Cost increased with the number of indicators. Over the study period, the proportion of all indicators being performed increased, and indicator six – psychosocial support referral or care had the biggest growth (almost 500%).

Conclusions

Variation in care for women presenting with early pregnancy bleeding to ED was identified. There is an evidence‐practice gap and need for inquiry into barriers and facilitators to prescribed clinical practice for this population.

Published: October 2024

Rosai–Dorfman disease (RDD) is a rare subtype of non–Langerhans cell histiocytosis. It is a benign disease with variable presentations, with breast involvement being an uncommon manifestation. In this paper, we present a case of breast RDD in a 59‐year‐old Chinese woman who presented with a painless, enlarging mass in her right breast, accompanied by skin changes and no palpable axillary lymph node. A mammogram and breast ultrasonography revealed a progressively enlarging lesion with a suspicious axillary lymph node, leading to an upgrade from Breast Imaging Reporting and Data System (BIRADS) score of 3 to 4A on interval imaging. Core biopsy of the breast mass and cytology of the right axillary lymph node confirmed extranodal RDD. After a 5‐year period of observation, excision was performed due to persistent symptoms. Local recurrence of RDD, with skin discolouration and thickening, was confirmed by skin biopsy 1 year and 9 months after the operation. To the best of our knowledge, this is the first reported case of breast RDD in Hong Kong.

Modern livestock production systems are characterized by a greater focus on intensification, involving managing larger numbers of animals to achieve higher productive efficiency and animal health and welfare within herds. Therefore, animal breeding programs need to be strategically designed to select animals that can effectively enhance production performance and animal welfare across a range of environmental conditions. Thus, this review summarizes the main methodologies used for assessing the levels of genotype‐by‐environment interaction (G × E) in cattle populations. In addition, we explored the importance of integrating genomic and phenotypic information to quantify and account for G × E in breeding programs. An overview of the structure of cattle breeding programs is provided to give insights into the potential outcomes and challenges faced when considering G × E to optimize genetic gains in breeding programs. The role of nutrigenomics and its impact on gene expression related to metabolism in cattle are also discussed, along with an examination of current research findings and their potential implications for future research and practical applications. Out of the 116 studies examined, 60 and 56 focused on beef and dairy cattle, respectively. A total of 83.62% of these studies reported genetic correlations across environmental gradients below 0.80, indicating the presence of G × E. For beef cattle, 69.33%, 24%, 2.67%, 2.67%, and 1.33% of the studies evaluated growth, reproduction, carcass and meat quality, survival, and feed efficiency traits, respectively. By contrast, G × E research in dairy cattle populations predominantly focused on milk yield and milk composition (79.36% of the studies), followed by reproduction and fertility (19.05%), and survival (1.59%) traits. The importance of G × E becomes particularly evident when considering complex traits such as heat tolerance, disease resistance, reproductive performance, and feed efficiency, as highlighted in this review. Genomic models provide a valuable avenue for studying these traits in greater depth, allowing for the identification of candidate genes and metabolic pathways associated with animal fitness, adaptation, and environmental efficiency. Nutrigenetics and nutrigenomics are emerging fields that require extensive investigation to maximize our understanding of gene–nutrient interactions. By studying various transcription factors, we can potentially improve animal metabolism, improving performance, health, and quality of products such as meat and milk.
Impact of convective clearance on intra‐dialytic potassium removal in chronic dialysis patients

Published: October 2024

Introduction

Hyperkalemia is frequently encountered and associated with cardio‐vascular mortality in chronic hemodialysis (HD) patients. While online hemodiafiltration (OL‐HDF) is thought to offer clinical benefit over high‐flux HD, the impact of convective clearance on intra‐dialytic potassium removal is unknown.

Methods

Chronic dialysis patients undergoing outpatient HD or OL‐HDF at a single center attached to a university hospital were recruited in a prospective observational study. Spent dialysate along with clinical and biological variables were collected during a single mid‐week session.

Results

We included 141 patients, with 21 treated with HD and 120 with OL‐HDF. Mean age was 65.7 ± 15.6 years with 87 (61.7%) men. Mean intra‐dialytic potassium removal was 69.9 ± 34.2 mmol. Patients on OL‐HDF and HD have similar intra‐dialytic potassium removal, with mean values of 69.1 ± 34.2 and 74.3 ± 35.0, respectively. In multivariate analysis, factors associated with intra‐dialytic potassium removal were (decreasing order of effect size): dialysate potassium (β −15.5, p < 0.001), pre‐HD serum potassium (β 9.1, p < 0.001), and session time (β 7.8, p = 0.003). In OL‐HDF patients, substitution flow was not associated with potassium removal.

Conclusion

In chronic dialysis patients, convective therapy provided by OL‐HDF does not affect potassium removal when compared with high‐flux HD. Moreover, the importance of convective volume is not associated with potassium clearance in OL‐HDF. Overall, session length and serum‐to‐dialysate potassium gradient are the main determinants of potassium clearance regardless of dialysis modality. Those results should inform clinicians on the optimal therapy in chronic dialysis patients in the era of OL‐HDF.

The aims of this study were to determine adaptation mechanism of sheep to salinity in drinking water. A group of 10 male sheep were used in a 6‐week of experiment, with 1 week for pre‐treatment period (Week 1), 4 weeks for during treatment period (Week 2 to Week 5), and 1 week for posttreatment period (Week 6). During the pre‐ and posttreatment periods, sheep consumed with fresh water. However, during treatment period, they were given with diluted seawater (DSW) at concentrations of 0.5%, 1.0%, 1.5%, and 2% for Weeks 2, 3, 4, and 5, respectively. Animal was offered 300 g concentrate and corn stover silage for ab libitum. Dry matter intake decreased as DSW increased, whereas sheep drinking DSW showed an increase in water intake and urine volume (p < 0.05). Body weight change decreased in 2% DSW. Sheep consuming 2% DSW exhibited higher plasma electrolyte levels compared to other groups. But plasma levels of AST, ALT, and creatinine were unaffected by DSW (p > 0.05). The elevated levels and excretions of urinary electrolytes were found in DSW groups (p < 0.05). Water balance was unaffected by DSW, except during the recovery period. It concluded that adapted sheep can consume DSW up to 1.5% without harmful effects.
