Case Study on Relocation of Port Infrastructure using the Randomized Expert Panel Opinion Marginalizing Procedure

We present a case study related to the relocation of parts of port facilities in a Black sea port in Varna (Bulgaria). As the city and the port expanded over the years, the east sector of the port ended up being in the middle of the city center. This causes environmental and spatial planning problems to both the city and the port area. We present several alternatives to relocate part of the industrial activities of the port to another site further to the west sector of the port and utilize the emptied space for recreational, public and social activities. We then apply the Randomized Expert Panel Opinion Marginalizing Procedure (REPOMP) to rank the alternatives. The procedure utilizes a hierarchy of criteria to assess the alternatives from four major aspects – environmental, social, technological and economical. A total of 12 experts provided their estimates on how the alternatives meet all criteria as well as on the relative significance of each criterion. Bootstrap simulation is utilized to not only find the total marginal criterion of each alternative, but also its distribution and best estimate. We also tested whether there is significant difference between the ranking scores of the alternatives.
Harmonics mitigation and non‐ideal voltage compensation utilising active power filter based on predictive current control

It is well-known that the presence of non-linear loads in the distribution system can impair the power quality. The problem becomes worse in microgrids and power electronic-based power systems as the increasing penetration of single-phase distributed generation may result in a more unbalanced grid voltage. Shunt active power filters (SAPFs) are used for improving the power quality and compensating for the unbalance grid voltage. This study presents a modification of the classical control structure based on the finite control set model predictive control (FCS-MPC). The proposed control structure can retain all the advantages of FCS-MPC, while improving the input current quality. Furthermore, a computationally efficient cost function based on only a single objective is introduced, and its effect on reducing the current ripple is demonstrated. The presented solution provides a fast response to the transients as well as compensates for the unbalanced grid voltage conditions. A straightforward single loop controller is compared to the conventional way of realising the active power filters, which is based on space vector pulse width modulation. The simulation results have been obtained from MATLAB/SIMULINK environment, while the obtained experimental results, utilising a 15 kVA power converter, highlight the effective performance of the proposed control scheme and verifies the introduced MPC-based method as a viable control solution for SAPFs.
Infant With SARS-CoV-2 Infection Causing Severe Lung Disease Treated With Remdesivir

We describe the case of an infant who developed severe pulmonary SARS-CoV-2 infection in the fifth week of life and was treated with remdesivir. We describe an ex-premature infant presenting with severe acute respiratory syndrome coronavirus 2 infection in the fifth week of life. In current reports, researchers indicate that acute symptomatic severe acute respiratory syndrome coronavirus 2 infection is relatively rare and much less severe than in adults. This case highlights that infection can be associated with life-threatening pulmonary disease in young infants and that infection can follow a similar disease course to that described in adults. We provide first data on the use of the novel antiviral remdesivir in a young child and an innovative approach to expedited approval from a multidisciplinary clinical team and bioethics committee for compassionate access to the drug.
The mediating role of primary TQM factors and strategy in the relationship between supportive TQM factors and organisational results: An empirical assessment using the MBNQA model

Abstract The mediating role among total quality management and business excellence model factors, including the role of strategy, has rarely been addressed empirically. This research examines the mediating effects of primary total quality management factors (operations management and measurement, analysis, and knowledge management) and strategy on the relationship between supportive total quality management factors (leadership, workforce, and customers) and organisational results using the Malcolm Baldrige National Quality Award (MBNQA) model as the framework. Based on responses from managers of 217 Saudi firms, the questions and hypotheses suggested in this research are examined using the structural equation modelling technique. The results show that: (a) supportive factors enhance primary factors; (b) strategy mediates the relationship between supportive factors and primary factors; (c) primary factors mediate the relationship between supportive factors and results; and, more importantly, (d) collectively and sequentially, the combination of strategy and primary factors mediates the relationship between supportive factors and results more strongly than their respective individual mediation effects separately. The findings support the systems perspective provided by the MBNQA model.
The current effect and growth of fresh-water algae.

Phycologists have long recognized that there are algae which grow only in torrents, or at least grow best in rapidly running water. Among these are Lemanea, Hildenbrandtia, Audouinella, Batrachospermum spp. , Hydrurus, and Cladophora spp. Microscopic types are represented by Gongosira, Lithoderma, Chamaesiphon, and several species of diatoms. (Butcher 1932, 1940, Fritsch 1935, Chapman 1941, Smith 1950, Tiffany 1951). In southern streams several other species such as Oedogonium kurzii, Vaucheria ornithocephala, and Compsopogon coeruleus are found only in rapids (Whitford 1956, Schumacher and Whitford 1959). For many years it was believed these rapids species grow in streams because lower water temperatures and better aerated water occur there. Evidence is lacking to bear out these assumptions. There is evidence, however, that some rapids species have a higher respiratory rate than corresponding lenitic species. Limnologists especially have come to recognize an "inherent current demand" for some species but offer no explanation (Welch 1952). As long ago as 1926 Ruttner partially explained the phenomenon. He pointed out that in quiet water a film deficient in vital materials forms at the surface of a plant or animal, and that in swift water this film is swept away thereby bringing more vital materials close to the absorbing surfaces. Moving water, he said, "is not absolutely, but rather physiologically, richer in oxygen and nutrients. " This "physiological richness" can be explained on the basis of the laws of cohesion and diffusion. In quiet water a material diffusing inward is lowest in concentration at the cell surface, and the concentration increases outward until full concentration is reached at some distance away from the cell (Fig. 1). This distance is one of the factors determining the diffusion gradient. In swift water some of the water low in concentration of the diffusing material is swept away bringing water of full concentration closer to the cell surface, thus shortening the diffusion distance and steepening the gradient. This increases speed of exchange between the cell and the surrounding water. For the smaller inorganic molecules the gradient extends outward about f4 mm. Evidence for this as well as for the existence of a "diffusion shell" is given in papers by Ferrell, Beatty, and Richardson (1955). They measured fluid-velocity profiles in small glass tubes using various colored and radio-active dissolved materials. In every case the profiles deviated from the expected theoretical figure near the tube wall. The deviation varied also with the size molecule of solute and the density of the solvent. Their conclusion, which seems entirely valid, is that diffusion outward from the quiet water near the wall produced these deviations. The deviation occurred within }/oo inch (0.26 mm.) of the wall (Figs. 2, 3). Furthermore, the deviation could not be
A machine learning framework for enhancing digital experiences in cultural heritage

PurposeDigital tools have been used to document cultural heritage with high-quality imaging and metadata. However, some of the historical assets are totally or partially unlabeled and some are physically damaged, which decreases their attractiveness and induces loss of value. This paper introduces a new framework that aims at tackling the cultural data enrichment challenge using machine learning.Design/methodology/approachThis framework focuses on the automatic annotation and metadata completion through new deep learning classification and annotation methods. It also addresses issues related to physically damaged heritage objects through a new image reconstruction approach based on supervised and unsupervised learning.FindingsThe authors evaluate approaches on a data set of cultural objects collected from various cultural institutions around the world. For annotation and classification part of this study, the authors proposed and implemented a hierarchical multimodal classifier that improves the quality of annotation and increases the accuracy of the model, thanks to the introduction of multitask multimodal learning. Regarding cultural data visual reconstruction, the proposed clustering-based method, which combines supervised and unsupervised learning is found to yield better quality completion than existing inpainting frameworks.Originality/valueThis research work is original in sense that it proposes new approaches for the cultural data enrichment, and to the authors’ knowledge, none of the existing enrichment approaches focus on providing an integrated framework based on machine learning to solve current challenges in cultural heritage. These challenges, which are identified by the authors are related to metadata annotation and visual reconstruction.
Regulators of Cell Division in Plant Tissues XII. A Cytokinin Bioassay Using Excised Radish Cotyledons

A rapid bioassay for cytokinins is described. This is based on the ability of these compounds to promote markedly the expansion of radish cotyledons excised soon after seed germination. The response, which is due largely to a promotion of cell enlargement, is inhibited by abscisic acid. Gibberellins, certain amino acids and calcium salts, naturally occurring substances without cytokinin activity, induce small growth increments in the assay. Cytokinin structure-activity relationships observed for the assay are very similar to those which apply in the tobacco-pith tissue culture assay.
Polymer Materials for High‐Performance Triboelectric Nanogenerators

As an emerging branch of energy conversion technologies, the triboelectric nanogenerator (TENG) pioneers a brand‐new path to effectively harness varieties of mechanical energies for the purpose of powering and/or sensing. Since its invention in 2012, the TENG has experienced a booming and revolutionary development in every respect, ranging from materials synthesis and modification, architecture design to performance optimization, power management, and application exploration. In comparison to the organic solar cell and organic light‐emitting diodes, TENG is a unique technique that opens the venue of using polymer materials (PMs) for harvesting mechanical energy. So far, by virtue of superior charge transfer and capturing capabilities during friction, various kinds of PMs have been developed and used as triboelectric materials in order to achieve high‐performance TENGs. Here, this work focuses on the utilization and development of PMs for the TENGs technology and first gives a summary of main PMs that are frequently adopted in currently reported energy‐harvesting TENGs. Second, several kinds of PMs used lately in a few novel TENGs for special or specific energy‐harvesting circumstances are introduced and highlighted. Finally, the perspectives on and challenges in developing high‐performance PMs toward TENGs technology are conceived and expected to be instructive to future research.
The evolving concept of access to justice in Singapore's mediation movement

Abstract This paper examines the key societal developments underpinning the growth of mediation in Singapore with a view to analysing the evolving conceptualisation of justice within mediation. The introduction of mediation corresponded with a shift from adversarial justice to an indigenous form of conciliatory justice, in which a respected mediator played an adviser role for the disputants and was trusted to ensure the fairness of the process. However, this trajectory was tempered by the need to ensure that Singapore mediation practice conformed with international practices concerning the protection of parties’ autonomy. The ambivalence concerning the mediator's role has resulted in uncertainty about whether the mediator bears primary responsibility for ensuring procedural and substantive fairness. The paper discusses the implications of this ambiguity and proposes ways to resolve it. The current phase of professionalisation in Singapore's mediation movement offers the opportune moment to resolve these existing tensions and to crystallise the mediator's role in facilitating access to justice.
Climate Response of Metasequoia glyptostroboides Inferred from Tree Rings, Secrest Arboretum, Wooster, Ohio, USA

Metasequoia glyptostroboides, a deciduous gymnosperm, also known as dawn redwood, was thought to be extinct until living members of the species were found in China in 1943. Analyzing the climate response of a transplanted stand of the trees can give insights into their physiological plasticity, into their use in restoration and reforestation, as well as into interpreting the environmental conditions of the geologic past from fossil Metasequoia. An annual ring-width chronology—spanning 1955 to 2010 and based on a stand of 19 M. glyptostroboides trees planted in Secrest Arboretum in northeast Ohio, USA—shows negative correlations with maximum monthly temperatures: with the strongest relationship with February and the warm months of June and July, all significant at the 99% confidence levels. A positive May to June precipitation correlation is the strongest moisture signal (p < 0.05) and the narrowest rings in the chronology occurred during the drought of 1987 to 1988, consistent with one of the warmest and driest Junes on record. These results have implications for the future as climate change affects the native and transplanted range of this species. Future response of this species to a changing climate will depend on the relative rates of warming maximum temperatures in the winter and summer, as well as changing moisture conditions during the summer months.
Influence of Photoperiod on Smolt Development and Growth of Atlantic Salmon (Salmo solar)

Atlantic salmon (Salmo salar) subjected in the spring to a constant photoperiod of 13 hr light/day or to simulated natural photoperiod (increasing day length) smoltified and grew rapidly before and after entering sea water. Others subjected to the reciprocal (complement) of natural photoperiod (decreasing day length in the spring) had the silvery color of smolts and grew rapidly but, unlike smolts, developed high condition factors while in fresh water. After they were transferred to sea water these fish ate less, grew more slowly, and had lower efficiencies of food conversion than those subjected to natural and constant photoperiod.Salmon experiencing reciprocal photoperiod had decreased sensitivity to external stimuli, suggesting reduced thyroid activity. Histological studies in June showed no differences in the appearance of the thyroid glands, suggesting no difference in thyroid activity between groups in natural and reciprocal photoperiod. Nor was there any difference in plasma osmotic and chloride le.
Upper boundaries of active galactic nucleus regions in optical diagnostic diagrams

The distribution of galaxies in optical diagnostic diagrams can provide information about their physical parameters when compared with ionization models under proper assumptions. By using a sample of central emitting regions from the Mapping Nearby Galaxies at Apache Point Observatory survey (MaNGA), we find evidence of the existence of upper boundaries for narrow-line regions (NLRs) of active galactic nuclei (AGNs) in optical Baldwin, Phillips & Terlevich (BPT) diagrams, especially in diagrams involving [S ii]λλ6716, 6731/Hα. Photoionization models can reproduce the boundaries well, as a consequence of the decrease of [S ii]λλ6716, 6731/Hα and [O iii]λ5007/Hβ ratios at very high metallicity. Whilst the exact location of the upper boundary in the [S ii] BPT diagram depends only weakly on the electron density of the ionized cloud and the secondary nitrogen prescription, its dependence on the shapes of the input spectral energy distributions (SEDs) is much stronger. This allows us to constrain the power-law index of the AGN SED between 1 Ryd and ∼100 Ryd to be less than or equal to −1.40 ± 0.05. The coverage of photoionization models in the [N ii] BPT diagram has a stronger dependence on the electron density and the secondary nitrogen prescription. With the density constrained by the [S ii] doublet ratio and the input SED constrained by the [S ii] BPT diagram, we find that the extent of the data in the [N ii] BPT diagram favours those prescriptions with high N/O ratios. Although shock-ionized clouds can produce line ratios similar to those from photoionization, the resulting shapes of the upper boundaries, if they exist, would likely be different from those of photoionizing origin.
Is Conscientiousness Always Associated With Better Health? A U.S.–Japan Cross-Cultural Examination of Biological Health Risk

In Western societies, conscientiousness is associated with better health. Here, we tested whether this pattern would extend to East Asian, collectivistic societies. In these societies, social obligation motivated by conscientiousness could be excessive and thus health-impairing. We tested this prediction using cross-cultural surveys of Americans (N = 1,054) and Japanese (N = 382). Biomarkers of inflammation (interleukin-6 and C-reactive protein) and cardiovascular malfunction (systolic blood pressure and total-to-HDL cholesterol ratio) were adopted to define biological health risk (BHR). Among Americans, conscientiousness was associated with lower BHR. Moreover, this relationship was mediated by healthy lifestyle. In contrast, among Japanese, the relationship between conscientiousness and BHR was not significant. Further analysis revealed, however, that conscientiousness was associated with a greater commitment to social obligation, which in turn predicted higher BHR. These findings suggest that conscientiousness may or may not be salubrious, depending on health implications of normatively sanctioned behaviors in varying cultures.
Detection of HCV RNA and NS5A Protein in Peripheral Blood Mononuclear Cells After Sustained Virological Response May Cause Viral Relapse

Chronic hepatitis C infection is the main causative agents for public health problem. Hepatitis C virus (HCV) is generally considered as hepatotropic virus but it can also infect the peripheral blood mononuclear cells (PBMCs). The aim of present study was to detect HCV RNA and non-structural protein 5 (NS5A) in PBMCs of the patients who achieved sustained virological response (SVR) and to explore their role in relapse. We investigated HCV RNA of genotype 3a in PBMCs of SVR responders Pakistani patients. A total of 62 patients who achieved SVR treated with interferon and ribavirin for 24 weeks were included in the study. PBMCs from blood were isolated by ficoll gradient centrifugation method using Ficoll reagent. Viral RNA in PBMCs was detected by quantitative real time PCR and HCV NS5A protein in was detected by immunofluorescence assay. Seven (11.3%) patients were relapsers. A positive association between viral RNA in the PBMCs and relapse was observed. Relapse occurred significantly more often in patients with HCV RNA in their PBMCs at SVR stage than the patients who did not have the RNA (25 % Vs 4.8 %, P=0.03 OR=6.66 CI%=1.16-38.13). HCV protein expression in PBMCs have showed the significant association with relapse (31.6% Vs 2.3%, OR=19.39; P=0.00). The study concludes that patients having HCV RNA and NS5A protein in PBMCs after achieving the SVR are more likely to go in relapse as compared to those negative for HCV RNA and protein in PBMCs.
Students’ Perceptions of Simulation-Based Learning in Speech Pathology: A Pilot Study

Due to increased student numbers and workforce limitations, speech pathology students have fewer opportunities to develop skills in working with adult populations in traditional clinical placements. Using simulation-based learning has proven to be advantageous in other disciplines. The use of simulation to develop clinical skills in speech pathology range of practice areas, including speech, language and swallowing in adults, has been less well researched. The aim of this study was to investigate students' overall perceptions about simulation-based learning, particularly their confidence related to specific clinical skills and perceived anxiety about working with adult clients. Six final year speech pathology students enrolled in either a 4-year undergraduate or 2.5-year masters program participated in this research. Students engaged in five simulation-based learning activities across one day. Purposefully developed pre- and post- surveys were completed to explore students' anxiety levels and perceptions of confidence regarding clinical skills across domains of foundation knowledge, case history, assessment, intervention, interaction and clinical reasoning, and anxiety levels. The Satisfaction with Simulation Experience (SSE) Scale was completed post-simulation experience. Students also participated in a focus group discussion following the simulation experience. Student median ratings of clinical skills improved from pre- to post-simulation across the six domains. All students reported that the simulation-based learning experience was valuable and reported increased levels of confidence and enhanced preparedness for their clinical placements. Findings from this study suggested that students value simulation-based learning and future research should explore learning outcomes from a longer, more intensive simulation program.
