Abstract
Human-wildlife conflicts in cities are becoming increasingly common worldwide and are a challenge to urban biodiversity management and landscape planning. In comparison to compensatory management, which often focuses on addressing emergency conflicts, precautionary management allows decision-makers to better allocate limited resources on prioritized areas and initiate long-term actions in advance. However, precautionary approaches have rarely been developed or applied in biodiversity conservation. Since 2020, human-raccoon dog conflicts in Shanghai, one of the largest cities in the world, have tripled in reported number due to the rapid spread of the species in the city from 70 residential districts in 2020 to 249 residential districts in 2022. Here, we use ensemble and circuit modeling to predict suitable raccoon dog habitat and identify their potential dispersal pathways to aid the development of precautionary management strategies. We find that raccoon dog distribution is positively associated with several anthropogenic factors, including residential buildings and nighttime light, which could be signs that the species’ foraging behavior has adapted to the urban environment. We find that raccoon dogs only occupy 10.1% of its suitable habitat, and thus there is a high potential for the expansion of the raccoon dog population and more frequent human-raccoon dog conflicts in the near future. We predict 60 potential dispersal pathways across Shanghai, seven of which cross densely human populated areas and are likely to trigger excessive conflicts. Based on our findings, we propose priority areas where precautionary management strategies, such as constraining stray animal feeding and wildlife-vehicle collision prevention, would potentially alleviate human-raccoon dog conflicts. We present the first study on the precautionary approach of human-wildlife conflict in China’s major cities, and provide a practical example of how comprehensive modeling approaches can be used as the foundation of precautionary management in urban landscapes.
Quantum causality constraints on kappa-Minkowski space-time
Authors: Franco Nicolas , Wallet Jean-Christophe 
Published: September 2022

Abstract
The κ-Minkoswki space-time provides a (quantum) noncommutative deformation of the usual Minkowski space-time. However, a notion of causality is difficult to be defined in such a space with noncommutative time. In this paper, we define a notion of causality on a (1 + 1)-dimensional κ-Minkoswki space-time using the more general framework of Lorentzian noncommutative geometry. We show that this notion allows specific causal relations, but limited by a general constraint which is a quantum generalization of the traditional speed of light limit.

Abstract
Shipping industries, one of the efficient modes of freight transport for global trade, are now being forced to demonstrate environmental commitment to reduce greenhouse gas emissions progressively. Stakeholders in the maritime community have proposed various countermeasures and action plans, including applying new energy resources for the future development of ship powers. This paper introduces a comprehensive review to categorize the pathways and highlight the core technological concepts, technical issues, current applications, implementation barriers, and future outlooks regarding integrating new energy resources into ship power systems, including single solar-powered and hybrid new energy resources. Eco-friendly energy sources were promising energy savings and GHG emission benefits. Still, integrating new energy source generation systems would significantly depend on several critical factors. Because ships require a large surface area for installing PV panels, the utilization of solar-assisted power generation on large-scale boats is currently uncommon. The energy generated by the PV generating system is mostly utilized for lighting and electricity. Integrating new energy source generating systems with current ship power systems is a viable approach for enhancing energy efficiency will likely be the focus of future ship-based energy system research. Furthermore, due to the variety of applications, the ship type, power system structure, and navigation area should be considered while selecting a suitable new energy source.

Abstract
Experimental uncertainty and measurement, particularly in engineering, have been increasingly emphasized over the last 20 years. Uncertainty analysis of ship model testing in seakeeping experiments based on International Organization for Standardization, Guide for Uncertainty of Measurements (ISO-GUM), report with recommendations published by ITTC (2008). In this paper, the uncertainties for free-running tests were performed for a model scale 1:62 as a benchmark model test at the Indonesian Hydrodynamic Laboratory (IHL). The benchmark model is representative of a full scale of 186 meters. The model has full appendages as well as a rudder and propellers to allow for free-running tests, natural roll period, free roll decay, and swing tests. Factors of basic uncertainty (type A and type B) are estimated using model tests. The standard deviation of the mean value of a repeated measurement is uncertainty type A. However, Type B uncertainty is estimated from manufacturing specifications. The uncertainty components resulting from both types are quantified by standard deviations. The uncertainty value of Type B is approximated by a corresponding variance. This study helps to understand the underlying uncertainty associated with this research, which resulted in a total geometry uncertainty value (Lpp, B, T, H,

KG

¯

, and kyy) of 0.17598% and the total uncertainty value of the instrument calibration results (wave height sensor and qualysis motion tracking) is 0.01161%. The results of this study are expected to minimize the impact of sources of uncertainty and allow the potential for underlying uncertainty to be corrected for the next seaworthiness test.

Published: September 2022

Abstract
With the increasing age of RV. Baruna Jaya III (30 years), the ships often face various problems. The continuous operation of the engine causes a decrease in its performance which eventually results in the failure of the main engine. For instance, damage to the main engine can stop operating of the ship at sea which eventually have various impacts on ship and life safety as well as operational cost. In this context, efforts to manage ships especially for the operation of main engine and its prevention from errors through real time monitoring and control system have become a major issue. This study aims to design a monitoring and alarm system for the main engine performance on the RV. Baruna Jaya III as the preliminary step for the development of the overall monitoring system. As a result, a design for data acquisition of the main engine performance parameters in real time and the design of a ship’s main engine failure alarm system have been developed using PLC-based design technology and a SCADA-based monitoring system. This system can be thus further built for the performance of the ship’s main engine, as part of management ship operations and maintenance policies.

Abstract
Mini LNG Carrier Ship is specially designed for the purpose of distributing Liquefied Natural Gas (LNG) throughout Indonesia and supporting the national program of generating 35.00 MegaWatt (MW). Indonesia’s vast territory with long distances requires an efficient transportation, including Mini LNG Carrier Ship to reduce costs, especially fuel and emission levels that meet the EEDI criteria set by the International Maritime Organization (IMO). One of the efficiency factors of Mini LNG Ship Carrier is obtained by optimizing the design, especially to the propulsion system. The propulsion system consists of the main engine and propeller. This study focuses on the selection of ship propulsion propellers, especially the type and number of propeller blades. The good propeller will have an impact on the level of energy efficiency. The research method used is a computational simulation using the Engine Propeller Matching (EPM) method. The study tested the B-Series propeller with an alternative number of propeller blades are (z) = 3, 4, 5, 6, and. 7. Calculating simulation results show that the analysis of the EPM computational results at 10 knots service speed, shows that the B6.40 propeller has a better efficiency value than the other propeller types (z = 3, 4, 5, and 7). Propeller type B6.40 produces a good level of efficiency according to the planned 2 x 250 KW engine performance diagram.

Abstract
According to data from the 2019 Ministry of Transportation Statistics Book, the number of national shipping fleets or ships in the country from 2015-2019 has doubled. However, from the potential of the current operating fleet, it shows that more than 75% of the fleet are over 20 years old. With such conditions, it is necessary to plan for ship maintenance and repairs to be as good as possible and to spend as little time as possible. This research aims to design a web-based intermediary application for ship repair planning services that can be accessed by using a website browser. The initial stage is to observe the condition of ship repair and planning from shipyard and shipowner perspectives through the literature and field study. From the result of the observation, then analyze what problems occur in the field and then arrange what functions or features are needed to be included in the design of the application to be able to solve these problems. Application design is done by making mock-ups, designing interfaces, creating databases and coding of the application system. After that, the application is tested and verified to find out that the application can run as intended and know the strengths and weaknesses of the application. The features in this application are designed to intermediary shipyard and shipowner in the ship repair planning process. The result of this preliminary web-based application design is by using this application, ship owners can search for docking space in available shipyards according to the schedule and place desired by the shipowner. In addition, by using this application, the shipowner can find out when the ship’s certificate expires so that they can prepare a schedule for conducting a survey. Then, both the shipyard and the shipowner can use this application to monitor and report on the progress of ship repair work.

Abstract
Although the design of trimaran hull has gained popularity at the end of the 20th century, there are few databases available to numerical analysis of trimaran hull. This paper presents a numerical study of the resistance of trimaran hull at various length ratio (S/L) 0.2, 0.3, 0.4 and Froude numbers 0.2 to 0.6 carried out by CFD simulation using FINETM/MARINE by NUMECA software and experimental data. Tri-A has a lower resistance than the trimaran B and C at low Froude number, but at hight Froude number 0.5 and 0.6, the Tri-A has a low resistance than the others. These results are compared with towing tank test data and obtained a lowest difference in the resistance of 0.98 % at TRI-A3. The lowest resistance for the trimaran model is Tri-C5 (Fr=0.6; S/L=0.4) with a total resistance coefficient (CT) of 65.89x10-4, this is due to favorable wave interference with a minimum IF of 0.02. The Interference Factor (IF) follows the same pattern in each configuration, however at maximum Fr, the minimal IF produced on Tri-A3(Fr=0.4; S/L=0.2), Tri-C4 (Fr=0.5; S/L=0.4), and Tri-C5 is 0.22, 0.12, and 0.02, respectively. Where the lowest IF indicates a positive effect because the resistance of the interference hull is lower hull at high speed. The results of this study are expected to be able to strengthen the data base in presenting the effect of interference resistance of the trimaran, which can then be applied directly in determining the magnitude of the ship’s propulsion at the preliminary design stage.

Study of the wear resistance of Hypereutectic Fe–Cr–C Hardfacing Alloy reinforced with carbide particles

Published: September 2022

Abstract
The microstructures and wear resistance of hypereutectic Fe–Cr–C hardfacing alloys reinforced with carbide particles was studied. The results showed that when the sizes of the M7C3 carbides were small, the wear resistance of the hardfacing alloy was considerably improved. During the wear process, the uniformly distributed small-sized carbides could also provide good support, and the uniform microstructure containing the fine M7C3 carbides could effectively reduce the force of the abrasive particles on the surface, evenly distribute the load, reduce the micro-cutting effect of the abrasive particles, and significantly improve the wear resistance of the hardfacing alloy. When the average size of the primary M7C3 carbides in the hardfacing alloy reached 0.5 μm, since the total volume fraction of the carbides of different sizes in the hardfacing alloy were basically the same, the reduction of the carbide size could significantly increase the phase interface of the M7C3 carbide and austenite. This could promote the occurrence of the M7C3 → M23C6 transformation, forming a two-phase composite structure with hard-core M7C3 carbide and soft-shell M23C6 carbide. This structure could reduce the interfacial stress between the M7C3 carbide and austenite and improve the spalling resistance of the carbides in the hardfacing alloy.

Published: September 2022

Abstract
The adsorption behaviours of bovine serum albumin (BSA) molecules on CoCrMo alloy and Al2O3 ceramic were considered as the main research object in this study, and atomic force microscopy (AFM) was used for investigation. The thickness of the BSA films as well as adsorption forces between the BSA molecules and samples were tested. The results indicate that the thickness of the adsorbed film is close to 2.09 nm, exhibiting lateral monolayer adsorption as the main mode of adsorption of deformed BSA molecules on the material surfaces; the adsorption force of the BSA molecules on CoCrMo alloy is greater than 85.9 nN, and the adsorption force on Al2O3 ceramic is greater than 68.2 nN. This difference in the adsorption force may be related to the fact that the surface positive charge of the CoCrMo alloy is greater than that of the Al2O3 ceramic.

Published: September 2022

Abstract
Sustainability certification systems play both an agenda-setting and practical role for a variety of architecture, planning, and engineering project types. The evolution of existing systems and the creation of new certification systems to address a broader set of social sustainability topics provide a unique opportunity to explore the different ways the industry is thinking about and applying social equity ideas to varied projects. We explore this diversity by conducting a content analysis of the guidance documents from eight sustainability certification systems to better understand how social equity is defined, the context in which the concept is applied, and how systems value the idea. The manner and degree to which systems engage with recognitional, procedural, and distributional aspects of social equity varies. Consequently, there is no guarantee that certification leads to real-world equitable outcomes. Moreover, sustainability professionals seeking to use certification systems to address unequal social impacts or benefits still need to bring a clear set of goals regarding equity of what and for whom, as well as ideas of how to measure and evaluate the distribution of social costs/benefits in order to put social equity into practice.

Abstract

BACKGROUND
Elevated blood pressure (BP) variability is predictive of increased risk for stroke, cerebrovascular disease, and other vascular brain injuries, independent of traditionally studied average BP levels. However, no studies to date have evaluated whether BP variability is related to diminished cerebrovascular reactivity, which may represent an early marker of cerebrovascular dysfunction presaging vascular brain injury.

METHODS
The present study investigated BP variability and cerebrovascular reactivity in a sample of 41 community-dwelling older adults (mean age 69.6 [SD 8.7] years) without a history of dementia or stroke. Short-term BP variability was determined from BP measurements collected continuously during a 5-minute resting period followed by cerebrovascular reactivity during 5-minute hypocapnia and hypercapnia challenge induced by visually guided breathing conditions. Cerebrovascular reactivity was quantified as percent change in cerebral perfusion by pseudo-continuous arterial spin labeling (pCASL)-MRI per unit change in end-tidal CO2.

RESULTS
Elevated systolic BP variability was related to lower whole brain cerebrovascular reactivity during hypocapnia (ß = −0.43 [95% CI −0.73, −0.12]; P = 0.008; adjusted R2 =.11) and hypercapnia (ß = −0.42 [95% CI −0.77, −0.06]; P = 0.02; adjusted R2 = 0.19).

CONCLUSIONS
Findings add to prior work linking BP variability and cerebrovascular disease burden and suggest BP variability may also be related to prodromal markers of cerebrovascular dysfunction and disease, with potential therapeutic implications.

ABSTRACT
Ingestion of plant and fungal glucosylceramides is known to reduce colon carcinogenesis and skin barrier damage in mice and humans. However, such effects in animal experiments have not been revealed for plant and fungal ceramides because the content of ceramides contained in plants and fungi is so low that the large amount required for animal experiments is difficult to obtain. Noting that the fungus shiitake mushroom (Lentinula edodes) is rich in a glucosylceramide, (4E,8E)-N-d-2′-hydroxypalmitoyl-1-O-β-d-glucopyranosyl-9-methyl-4,8-sphingadienine [Glc-d19:2(4E,8E,9Me)-h16:0], we developed a new method to purify this fungal glucosylceramide using ethanol precipitation and high-performance liquid chromatography. We also developed a new method to produce large amounts of a ceramide [d19:2(4E,8E,9Me)-h16:0] from this purified glucosylceramide using human glycoside hydrolase family 30 glucocerebrosidase (imiglucerase). These methods will be useful for elucidating the physiological function by ingestion of fungal ceramides in animal experiments.
