OPERATIONAL IDENTIFICATION OF THE SHIP’S POWER PLANT TECHNICAL CONDITION FOR SOLVING PROBLEMS OF PREVENTIVE MANAGEMENT
Authors: Saushev A. V. , Shirokov N. V.
Published: December 2022

Possible approaches to solving the problem of operational identification of the technical condition of ship power plants are considered. It is shown that the means of technical diagnostics used on modern ships are intended only for effective maintenance and repair of power equipment and they are not adapted for timely provision of information on the technical condition of the ship’s power plant necessary to ensure preventive management in abnormal operating modes. The definition of operational identification of the technical condition as a process of technical diagnostics of a ship’s power plant for the purposes of preventive and emergency management of its technical condition is given. The provision is substantiated that the means of technical diagnostics should not only identify the inoperable state of the elements of the ship’s power plant, but also predict its functioning mode after the shutdown of the inoperable generator unit and provide information to the warning control equipment about the necessary adjustment of external conditions to ensure its trouble-free transition to a partially operational state. It is shown that, unlike existing diagnostic tools, the goal-setting of operational identification of the technical condition of a ship’s power plant dictates the need to take into account such an important factor as the rate of the controlled parameter change, to determine the probable time for this factor to reach its maximum permissible value. The necessity of mandatory identification of inoperable elements of a ship’s power plant and the implementation of control actions aimed at eliminating an emergency situation until the overload of operable units and disabling them by means of protection is substantiated. It is established that the information obtained as a result of identification will allow the decision-making preparation system to formulate recommendations to the maintenance personnel and the preventive protection system about the necessary impacts on the ship’s power plant in order to exclude emergency situations. The main reasons for the overload of the ship’s power supply system are analyzed, algorithms for the practical solution of the problem of operational identification of the technical condition of the ship’s power plant for cases related to the overload of serviceable machines due to the shutdown of inoperable units are developed.

Published: December 2022

An overview of using pneumatic pressurization systems of icebreaker hulls in order to increase their icebreaking capability and a description of traditional design solutions in the design of systems are presented in the paper. It is noted that the design of systems is based on the methods of analogy and similarity, taking into account the results of field tests. Theoretical methods of taking into account the design features of the icebreaker hull and the technical characteristics of its power plant when determining the required air supply, its parameters, and outlets location are currently insufficiently developed. It is shown that the improvement of anti-icing devices of icebreakers provides an increase in their energy efficiency. The main areas of pneumatic charging devices improvement is to reduce the cost of driving supercharging units and the possibility of using secondary energy resources of marine diesel engines for their drive. The calculations results of the power required for the drive of air blowers depending on the air supply, other factors determining the energy consumption of the air blower system are indicated. The results of the conducted research confirm the possibilities of improving the anti-icing devices of icebreakers in order to increase their energy efficiency. The proposed method makes it possible to determine the required power costs and assess the possibilities of covering them with secondary energy resources with improved air blower drives. The maximum increase in energy efficiency can be achieved by choosing rational air supply parameters, reasonable placement of air supply openings, taking into account the design features of the icebreaker hull and the use of secondary energy resources of the main and auxiliary elements of the icebreaker power plant.
PREVENTIVE START-UP OF AN EMERGENCY DIESEL GENERATOR OF THE SHIP’S ELECTRIC POWER SYSTEM
Authors: Shirokov Nikolaj V.
Published: December 2022

The development of the method of preventive protection for the purposes of safe operation of the ship’s electric power system in emergency situations associated with malfunctions of its elements that occur during operation is considered in the paper. It has been shown that the existing devices form a command to start an emergency diesel generator at the moment when the voltage on the main switchboard busbars disappears. This circumstance causes a break in the power supply of responsible consumers of electric energy for a time equal to the start time of the emergency source. At the same time, the vessel loses control, and in most cases, the course. In this regard, it has been paid special attention in the paper to the development of a method for the preventive start of an emergency diesel generator, in which the launch command is formed before the vessel is de-energized, but with a real threat of this event. The conditions under which the preventive start of an emergency diesel generator should be carried out are formulated. Within the framework of the proposed approach, the energy state of the entire ship’s electric power system is predicted in the case of a decrease in its generating capacity, and, if necessary, a command to start an emergency source of electric energy is formed. At the same time, the most dangerous situation develops at a time when, in case of a failure of the generator unit of the main power plant, preventive unloading of the network turns out to be ineffective. It has been shown that there are emergency modes of vessel operation, such as flooding or fire in the room of diesel generators, in which the probability of simultaneous failure of all main electricity sources at once is especially high. The application of the proposed method of preventive start-up of an emergency power source will allow, in case of failure of at least one of the generator units of the main power plant operating in parallel, flooding or fire on the ship, to carry out structural adaptation of the system in advance to the malfunction that has arisen and go into a partially operational state, bypassing the emergency situation. At the same time, the interruption in the power supply of responsible consumers ensuring the safety of the vessel operation will either be significantly reduced or it will not happen at all. A functional diagram of a simple device implementing the proposed approach in practice is presented. A brief description of his work is given.

Authors: Háhn Judit , Radke Katarzyna , Dekker Ivonne
Published: December 2022

Virtual Exchange (VE) is a form of experiential learning that relies heavily on learning-by-doing and reflection. The present study draws on visual data comprising students’ perceptions of critical learning incidents presented under an imaginary magnifying glass. To complete this project-closing reflective activity, the students had to describe a critical moment that they had experienced during VE and present it in a visual form. Data was collected longitudinally, in three projects (2019, 2020, and 2021) that followed the same pedagogical design and focused on the theme of tourism. The collaborating universities were from three countries: Poland, Finland, and the Netherlands. We used the methods of qualitative content analysis and social semiotic analysis to investigate the students’ reflections. The findings show that the most frequently expressed themes were related to participation in the first meeting, joint production, use of a foreign language, and adaptation to change. The study contributes to a better understanding of the role of multimodal reflection in VE.

Authors: Dorr David , D'Autremont Chris , Richardson Joshua E , Bobo Michelle , Terndrup Christopher , Dunne M J , Cheng Anthony , Rope Robert
Published: December 2022

Background

High blood pressure (HBP) affects nearly half of adults in the United States and is a major factor in heart attacks, strokes, kidney disease, and other morbidities. To reduce risk, guidelines for HBP contain more than 70 recommendations, including many related to patient behaviors, such as home monitoring and lifestyle changes. Thus, the patient’s role in controlling HBP is crucial. Patient-facing clinical decision support (CDS) tools may help patients adhere to evidence-based care, but customization is required.

Objective

Our objective was to understand how to adapt CDS to best engage patients in controlling HBP.

Methods

We conducted a mixed methods study with two phases: (1) survey-guided interviews with a limited cohort and (2) a nationwide web-based survey. Participation in each phase was limited to adults aged between 18 and 85 years who had been diagnosed with hypertension. The survey included general questions that assessed goal setting, treatment priorities, medication load, comorbid conditions, satisfaction with blood pressure (BP) management, and attitudes toward CDS, and also a series of questions regarding A/B preferences using paired information displays to assess perceived trustworthiness of potential CDS user interface options.

Results

We conducted 17 survey-guided interviews to gather patient needs from CDS, then analyzed results and created a second survey of 519 adults with clinically diagnosed HBP. A large majority of participants reported that BP control was a high priority (83%), had monitored BP at home (82%), and felt comfortable using technology (88%). Survey respondents found displays with more detailed recommendations more trustworthy (56%-77% of them preferred simpler displays), especially when incorporating social trust and priorities from providers and patients like them, but had no differences in action taken.

Conclusions

Respondents to the survey felt that CDS capabilities could help them with HBP control. The more detailed design options for BP display and recommendations messaging were considered the most trustworthy yet did not differentiate perceived actions.
Machine Learning for the Prediction of Procedural Case Durations Developed Using a Large Multicenter Database: Algorithm Development and Validation Study (Preprint)
Authors: Kendale Samir , Bishara Andrew , Burns Michael , Solomon Stuart , Corriere Matthew , Mathis Michael
Published: December 2022

BACKGROUND

Accurate projections of procedural case durations are complex but critical to the planning of perioperative staffing, operating room resources, and patient communication. Nonlinear prediction models using machine learning methods may provide opportunities for hospitals to improve upon current estimates of procedure duration.

OBJECTIVE

The aim of this study was to determine whether a machine learning algorithm scalable across multiple centers could make estimations of case duration within a tolerance limit because there are substantial resources required for operating room functioning that relate to case duration.

METHODS

Deep learning, gradient boosting, and ensemble machine learning models were generated using perioperative data available at 3 distinct time points: the time of scheduling, the time of patient arrival to the operating or procedure room (primary model), and the time of surgical incision or procedure start. The primary outcome was procedure duration, defined by the time between the arrival and the departure of the patient from the procedure room. Model performance was assessed by mean absolute error (MAE), the proportion of predictions falling within 20% of the actual duration, and other standard metrics. Performance was compared with a baseline method of historical means within a linear regression model. Model features driving predictions were assessed using Shapley additive explanations values and permutation feature importance.

RESULTS

A total of 1,177,893 procedures from 13 academic and private hospitals between 2016 and 2019 were used. Across all procedures, the median procedure duration was 94 (IQR 50-167) minutes. In estimating the procedure duration, the gradient boosting machine was the best-performing model, demonstrating an MAE of 34 (SD 47) minutes, with 46% of the predictions falling within 20% of the actual duration in the test data set. This represented a statistically and clinically significant improvement in predictions compared with a baseline linear regression model (MAE 43 min; P<.001; 39% of the predictions falling within 20% of the actual duration). The most important features in model training were historical procedure duration by surgeon, the word “free” within the procedure text, and the time of day.

CONCLUSIONS

Nonlinear models using machine learning techniques may be used to generate high-performing, automatable, explainable, and scalable prediction models for procedure duration.

Published: December 2022

Background: There are 9,338 patients undergoing ARV therapy in Central Jakarta and based on data from April to June 2021, 3,651people are missing due to follow-up. Lost To Follow-Up (LTFU) is when the patient does not revisit after three months or more after thelast visit. Objective: Knowing the factors influencing ARV therapy in LTFU patients in Central Jakarta.Methods: This research is a case study research with a total of 12 informants consisting of LTFU patients, NGOs, doctors, and nursesfrom the priority health office in Central Jakarta. Data collection techniques using in-depth interviews and document review. Data analysis using framework analysis technique. Results: This study shows that the experience of LTFU patients wheninitially diagnosed with HIV experienced a pause in ARV therapy because they could not accept themselves as being HIV positive, andsome patients still did not understand ARV therapy treatment. ARV therapy decision-making is based on the motivation to be healthy andwant to see the child’s growth and development into adulthood. Patients feel that undergoing ARV therapy adds to activities that makethem unable to adjust their medication schedule, hampering work time because they must go to drug collection services. Some alsooften forget to bring medicine and feel the need to hide to take medicine when outside the house. The inhibiting factors for LTFU patientsare the effects of drugs; the COVID-19 pandemic condition; feeling healthy; tired of undergoing therapy; being far from health services,the number of costs incurred to go to services; not receiving complete information; and loss of support from the closest people.Conclusion: The government needs to improve strategies for LTFU patients to return to ARV therapy by optimizing the multi-month dispensing (MMD) program; inviting and providing education for family members or relatives of LTFU patients to take ARV therapy treatment by becoming a Drug Swallowing Supervisor (PMO); and it is important to support the design of HIV treatment telemedicine during the COVID-19 pandemic.

Published: December 2022

Bacterial secondary metabolites contain a diverse spectrum of biologically active compounds, including antimicrobials and antioxidants. Harnessing these products has enabled humans to fight against various diseases. But due to the overuse of antibiotics over the past few decades, many resistant strains of microbes are emerging. Therefore, there is a need to identify new sources of antimicrobial compounds. Actinomycetes are a group of bacteria known to produce antimicrobial compounds. This investigation aimed to identify, isolate and characterize actinomycetes with antimicrobial and antioxidant activity against pathogens acquired from MTCC. Sambhar Lake has a very potential group of actinomycetes producing several secondary metabolites. The study reports the antimicrobial and antioxidant potential of different extracts of actinomycetes. The sections of the actinomycetes were tested for their antagonistic activity against five pathogenic microorganisms. Antibacterial activity was reported in all five actinomycete isolates against Bacillus subtilis-MTCC 441, Escherichia coli-MTCC-1885, and Salmonella typhi-MTCC 733 but almost negligible activity against Staphylococcus aureus-MTCC 737 and Pseudomonas aeruginosa- MTCC 424 except for ACT-14 and ACT- 11. ACT14 had the highest antibacterial activity compared to all other isolates. The antioxidant capacities of all isolated extracts were evaluated for total phenols, total antioxidant activity, total reducing power, DPPH, and ABTS assays. Section of Pseudonocardia Antarctica ACT14 showed the highest (23.89±0.96) free radical scavenging of 2, 2-diphenyl1-picrylhydrazyl (DPPH), phenolic activity (194 ± 6.05) activity. This study was conducted to identify novel actinomycetes with antimicrobial properties. The sample ACT14 was found to be a novel actinomycete (Pseudonocardia Antarctica), and this isolate showed antimicrobial activity against all the test pathogenic bacteria used in the study. The culture was optimized for antimicrobial compound production. Since many pathogens tend to acquire antibiotic resistance, this study is essential as a novel source of antimicrobials that will provide a new weapon in the fight against infectious pathogens. Further purification and characterization of this compound are underway.

Authors: Louis Ramesh Ruben , Sulaiman Noor Adwa , Zakaria Zarina
Published: December 2022

Research aim: Recent occurrences of accounting failures have raised concerns over the quality of auditors’ performance. While there have been numerous studies on audit quality, there are limited research on what attributes constitute proper auditors’ performance. Thus, the objective of this study is to examine auditors’ performance attributes perceived to be important to achieve audit quality by auditors in practice. Design/ Methodology/ Approach: Data were obtained from 307 survey questionnaires received from auditors of large firms, small and medium-sized firms, and sole proprietors. Research finding: The study respondents perceived auditors’ performance related to competencies to perform the audit effectively and performing the audit in accordance with standards and regulations as the most significant attributes. These two key attributes were significant regardless of the types of audits performed (i.e. PLC or SME) and the position of the auditor (management or staff levels). On the other hand, attribute relating to providing individualised attention to clients was perceived to be of the lowest importance to the respondents. Theoretical contribution/ Originality: This study examined various behavioural and individual attributes for proper auditors’ performance, which enhances the literature on audit quality. Practitioner/ Policy implication: Key attributes and behaviours for auditors’ performance can be used by researchers and audit practitioners to set their performance benchmark and also used to assess any shortcomings. Research limitation: The respondents were mainly auditors of small and medium-sized firms and sole proprietors.

of environmental parameters on these organisms, are still rare. The aim
of this study is to provide a global overview on groundwater fauna
(stygofauna) research, including the historical evolution of research
topics and development of sampling methods. To achieve this, an
extensive review of accessible groundwater fauna data was conducted.
Over time, there has been an exponential increase in the number of
studies together with changing paradigms in the research focus,
particularly as sampling methods have developed and molecular analyses
become common. Studies on groundwater fauna are spatially uneven and are
dominated by studies in Europe and Australia, with few studies in
Africa, Asia and the Americas. This has resulted in a potential
geographic and climatically biased global view of stygofauna and
groundwater ecology. In the future, a more evenly distributed sampling
effort in underrepresented areas is necessary to enable global studies,
thus allowing a more comprehensive perspective on stygofauna
biodiversity, roles, and functional significances. This is increasingly
important with the accumulating knowledge of the sensitivities of these
ecosystems to anthropogenic activities, including climate change, and is
fundamental to effective management of these ecosystems.

Background Bipolar disorder’s potential endophenotypes include
neurological soft signs (NSS) and neurocognitive disorders (ND). Few
research, meanwhile, has coupled NSS and ND as combined endophenotypes
of bipolar disorder. object This study intends to investigate NSS and ND
and compare their differences in euthymic patients with bipolar disorder
(EBP), their unaffected first-degree relatives (FDR), and healthy
controls (HC). Additionally, search for potential endophenotypic
subprojects of NSS and ND and construct and verify a composite
endophenotypic. Methods The subjects were all Han Chinese and consisted
of 86 EBP, 81 FDR, and 81HC. Cambridge Neurological Inventory and
MATRICSTM Consensus Cognitive Battery tested NSS and ND independently.
Results All three groups displayed a trapezoidal distribution of NSS
levels and cognitive abnormalities, with EBP having the most severe NSS
levels and cognitive deficits, followed by FDR and HC. Among them, motor
coordination in NSS and Information processing speed (IPS), Verbal
learning (VL), and Working memory (WM) in neurocognitive function are
consistent with the traits of the endophenotype of bipolar disorder. The
accuracy in differentiating EBP and HC or FDRs and HC was higher when
these items were combined as predictor factors than in differentiating
EBP and FDR. Conclusion These results provide more evidence that motor
coordination, IPS, VL, and WM may be internal characteristics of bipolar
disease. When these characteristics are combined into a complex
endophenotype, it may be possible to distinguish bipolar disorder
patients and high-risk groups from normal populations.
The Impact of Geological Feature Shape on the Abundance and Diversity of Deep Sea Corals

Published: December 2022

The role of seamount gross geomorphology (shape) as an abiotic control
governing the abundance and diversity of deep-sea corals has not been
previously considered, but has the potential to provide
easily-accessible and transformative insight into deep water coral
community dynamics. This study aims to investigate the influence of
geological shape (e.g. atolls, islands, banks, guyots, conical, ridges)
on deep-sea coral genera and habitats in the Pacific Ocean to determine
whether seamount shape is an important predictor of deep water
biological communities. Multivariate analyses were used to test whether
the gross geomorphology (shape) of seamounts influences the abundance
and diversity of deep water coral genera. Seamounts across the entire
Pacific basin were categorized using a standard classification scheme to
determine their shape category. Across the 50 most abundant deep water
coral genera in the data set, all 50 showed a statically significant
preference for at least one geomorphology. Additionally, the abundance
of the different seamount shapes was not evenly distributed across the
Pacific basin. Gross geomorphology influences the abundance and
diversity of deep-sea corals across the central Pacific, which provides
insight into deep water coral community structure and resulting
conservation implications.

Seminal vesicle-rectal fistula is a very rare condition that corresponds
to a communication between the seminal vesicles and either superior,
middle or lower rectum. It is a very rare condition that can be seen as
a complication of anterior resection for rectal cancer.
Review of Incidence Angle Modifier Issues for Photovoltaic Energy Yield Estimations

The aim of this paper is to review the mathematical models proposed in
the literature that evaluate angular losses by means of the incidence
angle modifier in photovoltaic modules. The aim of this work is to
highlight the importance of considering not only the reflective losses
governed by the air-first interface of the photovoltaic module, but also
the losses governed by the effect of the accumulation of dust particles
on the surface of the modules under real operating conditions, known as
soiling. The Martin-Ruiz Model which derives from the mathematical
handling of the Fresnel equations and includes analytical solutions for
diffuse and reflected irradiance components, is presented as a robust,
accurate and reliable analytical model that contemplates these two
factors. With the implementation of the Martin-Ruiz Model in SISIFO, a
PV simulation software developed by the IES-UPM, optical losses at a 100
MW one-axis tracked PV plant in the Kalahari Desert were simulated. Four
different soiling scenarios were considered. The results suggest that
the incident angle modifier losses are between 44 to 64% larger than
those predicted when considering only the effect of refractive index
change. Simulation software integrating models that consider all of
these optical losses will improve the energy yield prediction of any
photovoltaic plant with more reliable estimations.
Vertical structure of clouds and precipitation during Arctic cold-air outbreaks and warm-air intrusions: observations from COMBLE

The Arctic is marked by deep intrusions of warm, moist air, alternating
with outbreaks of cold air down to lower latitudes. The typical vertical
structure of clouds and precipitation during these two synoptic weather
extremes is examined at a coastal site at 69°N in Norway. The Norwegian
Sea is a corridor for warm-air intrusions (WAIs) and frequently
witnesses cold-air outbreaks (CAOs). This study uses data from profiling
radar, lidar, and microwave radiometer, radiosondes and other probes
that were collected during the Cold air Outbreaks in the Marine Boundary
Layer Experiment (COMBLE) between 1 December 2019 and 31 May 2020.
Marine CAOs are defined in terms of thermal instability relative to the
sea surface temperature, and warm-air intrusions in terms of
stratification of moist static energy between the surface and 850 hPa.
Cloud structures in CAOs are convective, driven by strong surface heat
fluxes over a long fetch of open water, with cloud tops between 2-4 km.
The mostly open-cellular convection may contain substantial ice and
produce intermittent moderate precipitation at the observational site,
notwithstanding the low precipitable water vapor. In contrast, WAIs are
marked by high values of precipitable water vapor and integrated vapor
transport. WAI clouds are stratiform, with cloud tops often exceeding 6
km, sometimes layered, and generally producing persistent precipitation
that can be heavier than in CAOs.
