: Due to the deficiency of fresh water resources and the deterioration of groundwater quality worldwide, groundwater remedial technologies are especially crucial for preventing groundwater pollution and protecting the precious groundwater resource. Among the remedial alternatives, bioelectrochemical systems have unique advantages on both economic and technological aspects. However, it is rare to see a deep study focused on the information mining and visualization of the publications in this field, and research that can reveal and visualize the development trajectory and trends is scarce. Therefore, this study summarizes the published information in this field from the Web of Science Core Collection of the last two decades (1999–2018) and uses Citespace to quantitatively visualize the relationship of authors, published countries, organizations, funding sources, and journals and detect the research front by analyzing keywords and burst terms. The results indicate that the studies focused on bioelectrochemical systems for groundwater remediation have had a significant increase during the last two decades, especially in China, Germany and Italy. The national research institutes and universities of the USA and the countries mentioned above dominate the research. Environmental Science & Technology, Applied and Environmental Microbiology, and Water Research are the most published journals in this field. The network maps of the keywords and burst terms suggest that reductive microbial diversity, electron transfer, microbial fuel cell, etc., are the research hotspots in recent years, and studies focused on microbial enrichment culture, energy supply/recovery, combined pollution remediation, etc., should be enhanced in future.

Abstract Funding Acknowledgements Type of funding sources: None. Background Conflicting reports exist on the prevalence and clinical impact of interstitial fibrosis in right ventricular (RV) congenital heart disease (CHD). This study evaluates the longitudinal evolution of native myocardial T1 relaxation time (T1) in RV CHD. Methods On a 1.5T scanner, an ECG-triggered modified Look-Locker inversion recovery sequence (scheme 3(3)3(3)5) was acquired on a short-axis basal slice covering the RV and left ventricle (LV) on two consecutive CMR exams. Global and segmental (LV = 6, RV = 4) RV and LV T1 values  were calculated (Figure). Results Mean time between CMR exams for 36 included patients (age 34 ± 2y) was 22 ± 2 months. All LV segments and 81/88% of RV segments of first and second CMR could be analyzed, respectively.  T1 increased mildly but not significantly (table). There was no relationship of T1 to pulmonary regurgitation fraction, pulmonary stenosis or RV enddiastolic volume (p > 0.05). Global RV T1 of the second CMR was related to RV ejection fraction (RVEF): r = 0.353, 3.0 ± 1.4, p = 0.038. T1 of the infero-septal LV segment of first and second CMR, global LV T1 of second CMR and increase of T1 of global LV, anterior, antero-lateral and –septal LV segments, were related to age at CMR: r = 0.333 - 0.463, p < 0.05, respectively. Conclusions Native T1 values increased mildly in patients with stable RV CHD, which was not statistically significant probably due to the short to median follow-up. Global RV T1 appears to be related to RVEF which could be sign of increasing interstitial fibrosis whereas the relationship of LV T1 to age might be a physiological finding.

Abstract Objectives 1. Determine acceptability and feasibility of a phototherapy kiosk designed as a self-care intervention for low vitamin D; 2. Demonstrate that narrow spectrum ultraviolet (UV) B delivered by the kiosk is equivalent to recommended daily D3 supplementation to raise or maintain serum 25-hydroxyvitamin (OH)D levels at or above 30 ng/mL; and 3. Examine the relationship of demographic variables, including age, gender, body mass index, physical activity, ethnicity, skin type, season, and sun exposure to serum 25(OH)D levels in both treatment arms. Methods Participants were randomized to either the phototherapy kiosk (PK) for a treatment every other week or 600 IU D3 oral supplement (OS) daily, for 10 weeks. PK exposure was based on response to previous treatment and Fitzpatrick Skin Type category; subjects wore undergarments only and eye protection for treatments of 2–6 minutes duration. OS group received a one-time prescription of 70 capsules, dispensed by a research pharmacist. Primary outcome was serum 25(OH)D level. Results Final sample 88 adults; OS group n = 45 and PK group n = 43. Demographics: median age 35 years, mostly female (66%), no difference observed between groups for age, race/ethnicity, or marital status. No difference seen in skin type, birth location, sun exposure, or use of sunscreen. OS group had higher BMI and %body fat. Baseline 25(OH)D level were similar, P = 0.25. At 12 weeks median OS 25(OH)D 25.5 ng/mL and PK 30 ng/mL; P = .01. At 16 weeks, OS group 25(OH)D level 21 ng/mL and PK 27 ng/mL; P = .04. Adherence: OS 92% vs PK 100%. There were no reportable adverse events. Conclusions Use of PK every other week achieved higher serum levels of 25(OH)D than usual care vitamin D3 600 IU/day for 10 weeks, although both groups returned to baseline levels 30 days post-treatment. At a time when self-care measures are highly valued for health promotion, programmed UVB delivered via PK in the community appears to be a safe, efficacious alternative to oral D3 supplementation but requires recurring use. Results from this study suggest a need for early intervention in preventable health conditions impacting Warfighter performance and readiness, particularly pre-deployment when optimizing long-term wellness for duty in austere environments.

Abstract Microplastics (MPs) pollution has garnered significant interest as a serious environmental problem. To date, a large amount of research has been published on this topic. We analyzed the related studies to assess the global developments of MPs regarding the evolution, research trends, and hotspots by bibliometric. A total of 2,872 bibliographic records were retrieved from the Web of Science Core Collection, and CiteSpace 5.4 was used for bibliometrics. The results visually displayed the contributing countries, institutions, authors, keywords, and potential research directions in the MPs fields. The scientific developments in this field began in 2004 and have accelerated considerably since 2012. China and the USA are the leading countries in MPs research. The research on MPs is multidisciplinary and involves Ecology, Chemistry, Molecular Biology, Environmental Science, and Oceanography. Among these, Oceanography was the most connected with MPs and was the most well-developed. Overall, we mapped the development of MPs research and attempted a comprehensive discussion and understanding of scientific advances, as well as the progress made.

The Relationship

Vertical equity states that taxpayers whose positions are not the same should be treated differently while taking into consideration all the relevant characteristics. The main purpose of using the vertical equity principle is to require the redistribution of income in a way that reduces the income inequality of the society. The presented research aims to check the opinion of Slovenian tax system professionals on the principle of vertical equity. Slovenian results have been compared to a similar analysis carried out in Croatia, and partly with survey results from Bosnia and Herzegovina and the United States of America. The results show that the professional public agrees with the principle of vertical equity in the implementation of tax systems. All of the compared countries are similarly favourable towards vertical equity. However, this is also affected by the current tax arrangements of the individual countries.

The Relationship

Rarely has international law been investigated from a Business to Agency (B2A) or even Agency to Agency (A2A) perspective. In recent years, the “mushrooming” of agencies at European level has triggered the importance of looking more closely into the relationship of the agencies towards each other. Is there a struggle over competences and regulatory objects, and would such competition lead to desirable outcomes? In this paper I will first show that, due to the historical development of administrative law in Europe and the USA, the perception of the desirability of agency competition differs. I will then contrast these findings with EU pharmaceutical law and show that it tends to avoid competition. Also, in practice, competition among agencies is still exceptional for European pharmaceutical regulation. Finally, I conclude these findings and hint at the limits of the desired process for further coherence. Although a move towards even greater convergence in European risk regulation is desirable, it does have its limits set by the principle of conferral in Article 5 (1, 2) EU read in conjunction with the areas of shared competence and the competence to support, coordinate and supplement.
