Authors: Vorkapić Aleksandar , Radonja Radoslav , Martinčić-Ipšić Sanda
Published: July 2021

In this study, a framework for the application of shipboard energy efficiency monitoring, operational data prediction and reporting based on the ship’s measurement data and meteorological and oceanographic data by the geographic position and time of navigation is presented. General system theory in synergy with machine learning (ML) is used to construct the framework. The general system theory is utilized for identification and transition of components of the proposed framework of energy efficiency monitoring and prediction. A systematic investigation of the internal and external environment is conducted, and the definition of information flow between the individual components provided. Then, the external opportunities and threats that the system faces were opposed to internal strengths and weaknesses to formulate strategies in which weaknesses and threats of the system are offset by existing strengths and probabilities. After assessing the results of the strengths, weaknesses, opportunities and threats (SWOT) and threats, opportunities, weaknesses and strengths (TOWS) analysis, it can be concluded that the proposed framework is feasible and widely applicable in the maritime industry. The novelty is that the proposed framework is using on-board data processing and is integrated into the existing ship monitoring, decision-making and reporting system, thus satisfying the prerequisites for simple application.

Published: July 2021

One of the strategic development priorities of the Republic of Croatia is the development and construction of a modern telecommunications network and the availability of high-speed Internet throughout its territory, especially in rural areas and on islands. To enable this, it is important to build a reliable and resilient communication infrastructure. With the cooperation of all stakeholders in the construction, from telecom operators to local and state administrations responsible for the maritime demesne, and with efficient legislation, it is possible to achieve sustainable development of submarine cable infrastructure.
The paper provides an overview of the legal aspects of submarine optical cable infrastructure design and application at the national and international levels. Special attention is dedicated to the analysis of a national legal regime regulating the protection and sustainable use of submarine cables. Thus, the authors will provide critical analysis of a kind of dualism present in the application of the Ordinance on the Register of Concessions and the Ordinance on the Register of Concessions on the Maritime Demesne and offer suggestions for potential improvements of a national legal framework pertaining to the right of laying and legally protecting submarine cables.

Authors: Runko Luttenberger Lidija , Ančić Ivica , Luttenberger Axel
Published: July 2021

Biodiversity as a planetary boundary and sustainability are strongly related to fish stocks and fisheries that are regulated by a number of sources of law with the aim of achieving their sustainability. The paper analyses current application, impact and effectiveness of the Common Fisheries Policy that sets the rules for fishing fleets management in the European Union and for fish stocks conservation as well as the 2020 Report on its implementation by the European Court of Auditors. It also examines the present and potential implementation and effects of Blue Growth, Marine Strategy Framework Directive, United Nations legal framework and Sustainable Development Goals on fisheries and aquaculture activities in the Adriatic Sea, a semi-enclosed and biodiversity rich sea. Improvements in implementing marine ecosystem approach and marine spatial planning are proposed in policy and regulatory framework, focusing on characteristics of the Adriatic Sea. Resilient solutions require placing more focus on characteristics of regional seas and applying site-specific tailor-made solutions and less complex but efficient governance for the seas which entail integrated approach to exploitation and preservation of the resources and their health.
A gas turbine combustion chamber modeling by physical model
Authors: Glavan Ivica , Poljak Igor , Kosor Mate
Published: July 2021

The validity of the gas turbine unit model largely depends on the accuracy of the flue gas temperature value calculation at the gas turbine inlet (TIT). This temperature is determined by the maximum combustion temperature. In variable running mode, the temperature value is regulated by changing the ratio of air and fuel at the inlet to the combustion chamber. The paper presents a model of a gas turbine combustion chamber using Modelica, an object-oriented language for modeling complex physical systems with the aim of determining the temperature of combustion flue gases, specific heat capacity, enthalpy, and flue gas composition at different gas turbine loads.

Authors: Mrzljak Vedran , Anđelić Nikola , Lorencin Ivan , Sandi Baressi Šegota Sandi
Published: July 2021

This paper presents an exergy analysis of the whole turbine, turbine cylinders and cylinder parts in four different operating regimes. Analyzed turbine operates in nuclear power plant while three of four operating regimes are obtained by using optimization algorithms – SA (Simplex Algorithm), GA (Genetic Algorithm) and IGSA (Improved Genetic-Simplex Algorithm). IGSA operating regime gives the highest developed mechanical power of the whole turbine equal to 1022.48 MW, followed by GA (1020.06 MW) and SA (1017.16 MW), while in Original operating regime whole turbine develop mechanical power equal to 996.29 MW. In addition, IGSA causes the highest increase in developed mechanical power of almost all cylinders and cylinder parts in comparison to the Original operating regime. All observed optimization algorithms increases the exergy destruction of the whole turbine in comparison to Original operating regime - the lowest increase causes IGSA, followed by GA and finally SA. The highest exergy efficiency of the whole turbine, equal to 85.92% is obtained by IGSA, followed by GA (85.89%) and SA (85.82%), while the lowest exergy efficiency is obtained in Original operating regime (85.70%). Analyzed turbine, which operates by using wet steam is low influenced by the ambient temperature change. IGSA, which shows dominant performance in exergy analysis parameters of the analyzed turbine, in certain situations is overpowered by GA. Therefore, in optimization of steam turbine performance, IGSA and GA can be recommended.

Cultural influence on the aesthetic judgment of architecture
Authors: DAI ANBANG
Published: July 2021

Architects should consider the aesthetic experience of potential users when designingarchitectures. Previous studies have shown that subjective aesthetic judgment ofarchitectures is influenced by Structure features, and Western observers preferstructures that have curvilinear contours, high ceilings, and open spaces. The commonbuilding styles, however, vary across cultures, and may potentially influence observer'saesthetic preference. It remains unclear whether the preference for contours, ceilingheight, and openness is universal or culture dependent. To investigate this issue, thisstudy analyzes the aesthetic judgment of Chinese observers, and the results demonstratethat Chinese observers also prefer high ceilings and open spaces, similar to previousresults based on Western observers. Preference for curvilinear contours is also observedbut strongly interacts with ceiling height and openness. Post hoc analysis reveals thatChinese observers prefer curvilinear contours only when the ceiling is low and the spaceis closed. In sum, these results suggest that preferences for high ceilings and openspaces are observed in both Western cultures and in the Chinese culture. Thepreference for curvilinear contours, however, is less reliable in the Chinese culture.

Differential expression of interleukin 10 receptor subunit alpha in human epithelial ovarian cancer.
Authors: Mamoor Shahan
Published: July 2021

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding interleukin 10 receptor subunit alpha, IL10RA, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. IL10RA expression was significantly higher in high-grade serous ovarian tumors relative to normal fallopian tube. These data indicate that expression of IL10RA is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. IL10RA may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.
Effects of Calorie Labelling and Contextual Factors on Hypothetical Coffee Shop Menu Choices
Authors: Tapper Katy , Yarrow Kielan , Farrar Stephanie , Mandeville Kate
Published: July 2021

Objective: To examine effects of calorie labelling, motivation and habits on the calorie content of items selected from a coffee-shop menuboard. Methods: In one exploratory (n = 70) and one pre-registered (n = 300) laboratory study, participants viewed a hypothetical calorie-labelled or non calorie-labelled menuboard and selected their preferred item(s). Coffee shop drinking habits were measured using the Self-Report Habit Index, and motivation was assessed with three items asking about eating healthily, watching weight and reading calorie labels. Participants also estimated calories contained in various drinks.Results: Labelling did not significantly affect the total calorie content of items selected. However, as predicted, in the pre-registered study there was a trend toward moderation by motivation (p = .056) with less motivated participants showing relatively greater calorie selection when exposed to labelling. Participants with weaker habits took longer to select items (p =.002) but, contrary to predictions, were not more influenced by labelling. Higher motivation was associated with selecting fewer calories (p = .002), correctly recalling the presence/absence of labelling (p = .016) and better estimating calorie content (p < .001). Overall, participants significantly underestimated calories in higher calorie drinks but overestimated calories in lower calorie drinks. Conclusions: The results highlight the importance of underlying habits and motivation for obesity interventions and are relevant for the UK’s recent introduction of selective mandatory calorie labelling. In some instances, labelling may actually increase intake among those less motivated by health and weight concerns, but further research is needed to substantiate this concern.
How Feature Context alters Attentional Template Switching
Authors: Tünnermann Jan , Chelazzi Leonardo , Schubö Anna
Published: July 2021

In real-world tasks visual attention is rarely aimed at a single object. Humans rather“forage” the visual scene for information, dynamically switching attentional templates. Several visual search studies have found that observers often use suboptimal attentional control strategies, possibly to avoid effort. Here, we investigated with a foraging paradigm if observers’ reluctance to switch between attentional templates increases with template specificity. To that end, we manipulated the feature context of displays in which participants “foraged” moving stimuli on a tablet-PC. Experiment 1 (N = 35) revealed a decline in switching tendency and foraging efficiency with increasing feature-space distance between target alternatives. Experiment 2 (N = 36) found even lower flexibility with distractor color close to, and strongest impairments with distractor color in between target colors. Our results demonstrate that visualinformation sampling is most flexible when broad (instead of very specific) templates and relational search strategies are possible (e.g., attending “redder” objects), with implications for both attention research and applications, especially in visual-foraging-like tasks, such as baggage screening or medical image assessment.
Do children think it is important to predict learning and behaviour problems, and do they think genetic screening has a role to play in this?
Authors: Fields Diana , Asbury Kathryn
Published: July 2021

This study represents an attempt to foresee some of the psychological, practical and social issues that could arise from incorporating DNA screening into education, from the perspective of young children. Children aged 4-10 (n=165) were asked for their views on whether DNA screening for learning and behaviour differences would be helpful or harmful. A content analysis of their qualitative responses to a series of scenarios derived six categories: 1. ‘Worried about being – and being seen as – different’; 2. ‘Beliefs about the origins of learning and behaviour’; 3.’Testing is harmful’; 4. ‘Testing could help’; 5. ‘How soon is too soon for testing?’; and 6. ‘What’s the point? Findings suggest it is important to listen to children’s views, and to consider their understanding, when planning the future use of DNA data; and that even very young children can make useful contributions to public debate in this area. The issues highlighted can potentially be addressed by high quality education that is accessible from the first days of primary school.
Loneliness mediates the association between mindful emotion regulation and perceived social support in parents during the COVID-19 pandemic
Authors: Zhang Na , Russell Beth , Park Crystal L. , Fendrich Michael
Published: July 2021

The COVID-19 pandemic has introduced unprecedented challenges and demands for parents or caregivers of children who experienced disruptions in social support and feelings of isolation. Mindful emotion regulation may be a resilient factor for parents’ psychosocial outcomes. Mindful emotion regulation refers to individuals’ inherent capacities to regulate emotions mindfully, i.e., through paying attention to one’s experiences in the present moment nonjudgmentally. Based on the theoretical and empirical literature associating mindful emotion regulation with loneliness and perceived social support, the current study tested the effects of mindful emotion regulation on later changes in perceived social support and loneliness in U.S. parents during the pandemic. Participants were 147 parents/caregivers who were living with at least one child or adolescent in their household during the pandemic in the USA. Data were collected from a national online sample at four time points: baseline (April 7-21, 2020), 30-, 60-, and 90-days later. Results of longitudinal mediational structural equation modeling showed that mindful emotion regulation was directly associated with increased perceived social support and decreased loneliness. Moreover, mindful emotion regulation was also associated with perceived social support indirectly through its effects on loneliness. Focusing on the needs of parents is important for promoting family and child wellbeing to ameliorate negative health consequences. More research is needed to elucidate whether and how mindful emotion regulation may be beneficial for parents in the social relationship domain.

Authors: Chintakrindi Sriram , Gupta Suditi
Published: July 2021

Background: To investigate how the independent variables: veteran status, brain injury, drug use, and alcohol use predict risk for rule violations and assaulting jail or prison staff while incarcerated. This study used aggregated and disaggregated data to demonstrate relationships between exposure and outcomes. Methods: Cross-sectional survey data was collected from the Survey of Inmates in State and Federal Correctional Facilities (SISFCF), 2004 (n = 14499). Chi-square, Cochran-Mantel-Haenszel (CMH), and logistic regression were conducted to determine the relative contribution of the independent variables in predicting rule violations and assaulting jail or prison staff while incarcerated. The research study tested a number of hypotheses that are listed in the hypotheses section of the research study. Results: The findings from the logistic regression conducted in this study demonstrate a significant relationship between veteran status, alcohol use, and brain injury status and the dependent variable: found guilty or written up for jail or prison rule violations while incarcerated. Conclusion: Alcohol use and brain injury present serious risks for maintaining public health and safety of incarcerated veterans and non-veterans. Daily or almost daily consumption of alcohol was the strongest predictor of jail or prison rule violations. Therefore, researchers and practitioners should continue to develop interventions and policies for reducing alcohol consumption of individuals in contact with the criminal justice system.

Authors: Kasthuriarachchi Sanvitha , Liyanage S. R.
Published: July 2021

A combination of different machine learning models to form a super learner can definitely lead to improved predictions in any domain. The super learner ensemble discussed in this study collates several machine learning models and proposes to enhance the performance by considering the final meta- model accuracy and the prediction duration. An algorithm is proposed to rate the machine learning models derived by combining the base classifiers voted with different weights. The proposed algorithm is named as Log Loss Weighted Super Learner Model (LLWSL). Based on the voted weight, the optimal model is selected and the machine learning method derived is identified. The meta- learner of the super learner uses them by tuning their hyperparameters.  The execution time and the model accuracies were evaluated using two separate datasets inside LMSSLIITD extracted from the educational industry by executing the LLWSL algorithm. According to the outcome of the evaluation process, it has been noticed that there exists a significant improvement in the proposed algorithm LLWSL for use in machine learning tasks for the achievement of better performances.

Effect of Abiotic Stress on Onion Yield: A Review
Authors: Ratnarajah Vassanthini , Gnanachelvam Niroash
Published: July 2021

Onion (Allium cepa L.) is a spice crop and a valuable economic crop cultivated in a variety of environments around the world. Because of its export demand, it is extremely important in terms of foreign exchange. Drought stress, waterlogging stress, heat stress, cold stress, and salinity stress all have an impact on onion growth, production, and yield in different ways. A lack of water causes low productivity, therefore to increase onion yield, a constant supply of water is needed. Onions are particularly susceptible to salt stress. The number of bulbs per unit area, height, and fresh weight of onion bulbs, are all affected by salinity in irrigation water. It has an effect on bulbing and the quality of harvested bulbs. Waterlogging has a major effect on bulb development and yield at various growth stages. Waterlogging stress in onions may prevent moving from source to sink, lowering bulb yield. The possible flavor of onions can be affected by the surrounding climate. The bulbing response is influenced by temperature, and the degree to which it is influenced varies by variety. As the temperature increases, the number of leaves decreases. The bulb diameter, bulb weight, and bulbing index (bulb/neck diameter) all increase as the temperature rises. This review provides an in-depth description of the effect of abiotic stress on onion yield.

The use of biomass combustion ash as a reinforcing filler has taken the attention in recent years to reduce the overall production cost and increase the mechanical properties of plastics. This study evaluates the effect of biomass boilers ash (BBA) as a reinforcing filler on polyamide 6 composites (PA6). The chemical composition and thermal stability of BBA were analyzed by X-ray fluorescence (XRF), Thermogravimetric analysis (TGA), and Differential thermal analysis (DTA) thermographs. Test samples were prepared by varying the ash content (2.5%, 5%, 7.5%, and 10%), and also samples were prepared without adding ash as a control. Moreover, surface modification was carried out by using N-2 (Aminoethyl) 3-aminopropyl triethoxy diamino-silane as a possible coupling agent for BBA and it was tested by varying the coupling agent concentration (0.5%, 1%, and 2%) by dry process and the samples were prepared by extrusion and injection molding processes. Comparative analysis of the degree of crystallinity, mechanical properties including tensile, flexural, and thermal properties were tested. The highest degree of crystallinity was obtained with 7.5% BBA-filled composites. The addition of 2% surface-modified BBA (SBBA) filled composites (PA6 / 10% Ash 2% CA) showed an increase of tensile strength and elongation at break than the 10% unmodified BBA (UBBA) (PA6/ 10% Ash) filled composites. Stress at peak and bending modulus values in the flexural test data were increased up to 10%. But it was significantly reduced with the increasing of modifying agent concentration due to the increment of stiffness of the composite.

Published: July 2021

Polycystic ovary syndrome (PCOS) is the commonest endocrine disorder of young women with long-term metabolic risk and prevalence among pre-marital Sri Lankan women is 6.3%. Inheritance of PCOS is likely to be oilgogenic; the genetic basis remaining largely unknown in view of the complex pathophysiology. The genetics of expression of PCOS requires an in-depth study, particularly among Sri Lankan women who have a greater metabolic risk from an early age. The emergence of an unanimously accepted genetic marker for susceptible PCOS was affected based on inconsistent findings. In this review, we summarize the common genetic polymorphisms of PCOS from different countries and outline some genetic polymorphisms that are potentially associated with the risk of PCOS in Sri Lankan women. This information could uncover candidate genes associating with PCOS, which will be valuable for the development of novel diagnostic and treatment method.

Collaboration amongst stakeholders in a construction project plays a significant role in managing and completing a project successfully. It specifically helps in interface management amongst the stakeholders. Among the various aspects of collaboration, there are two key factors that predominant. Firstly, the psychological factors that define a person as a natural collaborator, and secondly, the project-level enablers that determine a collaborative project. Therefore, in this study, two inductive theories are developed- one for psychological factors and another for project-level enablers of collaboration. This study aims to identify the key psychological factors and project enablers associated with collaboration and develop a conceptual framework to measure collaboration in a construction project. The workflow of the conceptual framework is developed in the first part of the research, and the input requirements are quantified. Robust hypothesis testing methodology is adopted to identify the key psychological factors and project enablers. Hypotheses testing yields three specific psychological factors for defining a person as a natural collaborator, and six enablers are essential for facilitating project collaboration. These results are used as input parameters in the derived conceptual framework to measure the level of collaboration in a construction project.

OBJECTIVE

While several studies have compared the feasibility and safety of mechanical thrombectomy (MT) for distal large-vessel occlusion (LVO) strokes in patients, few studies have compared MT with intravenous thrombolysis (IVT) alone. The purpose of this systematic review was to compare the effectiveness and safety between MT and standard medical management with IVT alone for patients with distal LVOs.

METHODS

PubMed, Google Scholar, Embase, Scopus, Web of Science, Ovid Medline, and Cochrane Library were searched in order to identify studies that directly compared MT with IVT for distal LVOs (anterior cerebral artery A2, middle cerebral artery M3–4, and posterior cerebral artery P2–4). Primary outcomes of interest included a modified Rankin Scale (mRS) score of 0 to 2 at 90 days posttreatment, occurrence of symptomatic intracerebral hemorrhage (sICH), and all-cause mortality at 90 days posttreatment.

RESULTS

Four studies representing a total of 381 patients were included in this meta-analysis. The pooled results indicated that the proportion of patients with an mRS score of 0 to 2 at 90 days (OR 1.16, 95% CI 0.23–5.93; p = 0.861), the occurrence of sICH (OR 2.45, 95% CI 0.75–8.03; p = 0.140), and the mortality rate at 90 days (OR 1.73, 95% CI 0.66–4.55; p = 0.263) did not differ between patients who underwent MT and those who received IVT alone.

CONCLUSIONS

The meta-analysis did not demonstrate a significant difference between MT and standard medical management with regard to favorable outcome, occurrence of sICH, or 90-day mortality. Prospective clinical trials are needed to further compare the efficacy of MT with IVT alone for distal vessel occlusion.
