“MATTERS OF MUTUAL INTEREST” FOR PURPOSES OF A STRIKE Vanachem Vanadium Products (Pty) Ltd v National Union of Metalworkers of South Africa [2014] 9 BLLR 923 (LC)
Authors: ME Manamela  
Published: October 2021

The concept of “matters of mutual interest” is used in a number of sections and definitions in the Labour Relations Act 66 of 1995 (LRA). This is an indication that this is an important concept in labour law, and it is therefore imperative that it be properly understood. At times this concept is misunderstood to be synonymous with disputes of interest, however, that is not necessarily the case. This concept is used, for example, in the definitions of both collective agreement and strike contained in section 213 of the LRA. It is also used in section 134 of the LRA which deals with dispute resolution. In spite of its importance, the LRA does not provide a definition for the concept. As a result the interpretation of this concept has raised some challenges as it will be seen from Vanachem Vanadium Products (Pty) Ltd v National Union of Metalworkers of South Africa ([2014] 9 BLLR 923 (LC)). In this matter, the court was required to determine whether certain matters were matters of mutual interest for purposes of strike action. Section 213 of the LRA defines “strike” as: “the partial or complete concerted refusal to work, or the retardation or obstruction of work, by persons who are or have been employed by the same employer or by different employers, for the purpose of remedying a grievance or resolving a dispute in respect of any matter of mutual interest (author’s own emphasis) between employer and employee …”
Based on the above definition, the purpose of the refusal to work by employees must be to “remedy a grievance” or “resolve a dispute in respect of matters of mutual interest between the employer and employees”. A dispute which does not fall under matters of mutual interest is therefore not covered for purposes of a strike. The correct interpretation of this concept in this context is important as it ultimately determines whether or not a trade union and its members may strike in support of a particular demand. This note will consider the concept of “matters of mutual interest” and the way it has been interpreted and then evaluate the finding in Vanachem Vanadium Products v NUMSA in order to determine whether the court was correct in its determination of whether disputes or demands raised by NUMSA for purposes of a strike were matters of mutual interest or not.
Liver and COVID-19 - A Review and Clinical Approach
Authors: Malnick Stephen , Fisher David L. 
Published: October 2021

:
Liver enzyme abnormalities occur frequently in patients diagnosed with Coronavirus disease
2019 (COVID-19). It has been suggested that patients with severe acute liver injury are more
likely to be admitted to intensive care, require intubation or renal replacement therapy and their
mortality rate is higher than patients without severe acute liver injury. This review article explores
the possible aetiologies of liver dysfunction seen in patients with COVID-19 and also the effect of
COVID-19 on patients with pre-existing liver disease. Finally, we suggest clinical approaches to
treating a patient with liver enzyme disturbance and COVID-19 and also caring for patients who require
liver transplantation in the COVID-19 era.
A Fenomenologia da diferença Ôntico-Ontológica
Authors: Marder Michael 
Published: October 2021

Abstract
This paper focuses on Martin Heidegger’s reading of the Hegelian phenomenology of spirit as a veiled critique of Edmund Husserl’s phenomenology of consciousness. Ultimately, I argue, Heidegger will acknowledge the insufficiency of either phenomenology, concerned exclusively with Being or with beings, and will hint at the possibility of a third kind of phenomenology unfolding between the two - the phenomenology of ontico-ontological difference.
Fluid–Structure Interaction Vibration Experiments and Numerical Verification of a Real Marine Propeller
Authors: Lou Benqiang , Cui Hongyu 
Published: October 2021

Abstract
The design of lifting blade shapes is a key engineering application, especially in domains such as those of marine propellers, hydrofoils, and tidal energy converters. In particular, the excitation frequency must be different from that of the structure to avoid resonance. The natural frequency in the cases where the fluid–structure interaction (FSI) is considerably different if considering the coupling added mass (AM) of the water. In this study, vibration experiments were performed using a real propeller in air and water. The modal parameters, natural frequencies, and mode shapes were determined. Validations were performed using 3D solid and acoustic elements in a direct coupling finite element format. The modal results and AM ratios were in agreement with the experimental results. Convenient application and high efficiency are basic requirements for an engineering application. Therefore, an empirical formula was established for the first-order FSI natural frequency to enable rapid estimation, thereby satisfying this requirement.
Estimation of Ship Repair Time Using the Genetic Algorithm

Published: October 2021

Abstract
Ship maintenance is regulated by both the state and the classification society. The scope of maintenance works depends on the age of the ship and includes a dock, intermediate and special inspection. The problem is to estimate the reliable time of the ship maintenance and the downtime at the shipyard. The purpose of this article is to develop a more accurate model to predict a ship’s overall maintenance time. A multiple linear regression model is developed to describe the impact of historical data on hull repair, painting time, piping, age, structural and hull plate replacement for ship maintenance. In the literature, the least squares method is used to estimate unknown regression coefficients. The original value of the article is the use of a genetic algorithm to estimate coefficient values of the multiple linear regression model. Necessary analysis and simulations are performed on the data collected for oil and chemical or product tankers. As a result, a significant improvement in the adequacy of the presented model was identified.
Journal Bearing Performance Prediction Using Machine Learning and Octave-Band Signal Analysis of Sound and Vibration Measurements
Authors: Moschopoulos Marios , Rossopoulos Georgios N. , Papadopoulos Christos I. 
Published: October 2021

Abstract
Journal and thrust bearings utilise hydrodynamic lubrication to reduce friction and wear between the shaft and the bearing. The process to determine the lubricant film thickness or the actual applied load is vital to ensure proper and trouble-free operation. However, taking accurate measurements of the oil film thickness or load in bearings of operating engines is very difficult and requires specialised equipment and extensive experience. In the present work, the performance parameters of journal bearings of the same principal dimensions are measured experimentally, aiming at training a Machine Learning (ML) algorithm capable of predicting the loading condition of any similar bearing. To this end, an experimental procedure using the Bently Nevada Rotor Kit 4 is set up, combined with sound and vibration measurements in the vicinity of the journal bearing structure. First, sound and acceleration measurements for different values of bearing load and rotational speed are collected and post-processed utilising 1/3 octave band analysis techniques, for parametrisation of the input datasets of the ML algorithms. Next, several ML algorithms are trained and tested. Comparison of the results produced by each algorithm determines the fittest one for each application. The results of this work demonstrate that, in a laboratory environment, the operational parameters of journal bearings can be efficiently identified utilising non-intrusive sound and vibration measurements. The presented approach may substantially improve bearing condition identification and monitoring, which is an imperative step to prevent journal bearing failures and conduct condition-based maintenance.

In the modern world, it is impossible not to notice the rapid development of information technologies, the Internet, and online space. These technologies are suitable for asynchronous learning-learning in off-line mode. Today, there are many educational platforms and systems. The paper presents the experience of using the Moodle platform for distance learning for all categories of students in order to optimize and monitor their extracurricular work. Asynchronous learning is a form of distance learning that is carried out with a time delay, the teacher and the student do not contact directly. The student is trained without reference to a specific time and anywhere in the world. The only limit may be the deadline for completing the task. The introduction of such educational technology shows the possibility and feasibility of practical application of distance learning methods for independent training of students. This article also discusses the issue of creating and using a presentation when organizing classes in remote mode. The standard presentation is used as a supplement to the teacher's presentation. In the remote mode, it should replace the teacher, so when developing it, it is necessary to take into account a number of requirements. We are trying to offer an optimal presentation option with possible examples of slides that show examples of tasks

Macro Sustainability Accounting: A New Way to Prepare Value Added Statement
Authors: Ali Mohammed Ataallah , Abdullah Salman Hussein 
Published: October 2021

Traditional accounting takes only one dimension (economic) in calculating the value added of the company, and all other aspects (including environmental and social) are neglected, and despite the emergence of Sustainability Accounting and the interest of companies in preparing sustainability reports, these reports are suffering from many problems, including multiple metrics used in measuring companies (cash, quantity and lavish). In addition, these reports may reach dozens of pages in some companies and this causes the problem (information overload) which affects the qualitative properties of accounting information such as appropriate and relative, which requires the need to find a tool that can measure the Sustainability Unit of standard measurement, so easy to understand and use in comparison with standard reference (benchmark).
The problem of research is the neglect of the cost of non-sustainability borne by society and the planet as a result of companies exercising their activities inefficiently, where these costs do not appear in the records of the companies causing them because of the common saying (that what cannot be measured cannot be managed and therefore cannot be held accountable) and this encourages companies to neglect sustainability.
As a result, the research aims to find an objective way to measure the cost of non-sustainability incurred by society and the planet as a result of the inefficiency of these companies in the management of their activities, therefore, these costs can be charged to the companies that cause them, as this will play a significant role in changing the perception of corporate managers towards sustainability.

The research led to a set of results, including the palaces of accounting tools (all branches) in measuring the cost of non-sustainability in cash.
The research presented a set of recommendations, the most important of which is the need to take into account macro sustainability accounting by the stakeholders of this profession, and develop value-added statement using the technologies developed by the researcher (SVA$) because of its role in measuring the cost of non-sustainability critically, which will have a significant role in changing the corporate view for neglecting sustainability

AbstractGraph theory has been widely used to quantitatively analyze complex networks of molecules, materials, and cells. Analyzing the dynamic complex structure of extracellular matrix can predict cell‐material interactions but has not yet been demonstrated. In this study, graph theory‐based mathematical modeling of RGD ligand graph inter‐relation is demonstrated by differentially cutting off RGD‐to‐RGD interlinkages with flexibly conjugated magnetic nanobars (MNBs) with tunable aspect ratio. The RGD‐to‐RGD interlinkages are less effectively cut off by MNBs with a lower aspect ratio, which decreases the shortest path while increasing the number of instances thereof, thereby augmenting RGD nano inter‐relation. This facilitates integrin recruitment of macrophages and thus actin fiber assembly and vinculin expression, which mediates pro‐regenerative polarization, involving myosin II, actin polymerization, and rho‐associated protein kinase. Unidirectional pre‐aligning or reversibly lifting highly elongated MNBs both increase RGD nano inter‐relation, which promotes host macrophage adhesion and switches their polarization from pro‐inflammatory to pro‐regenerative phenotype. The latter approach produces nano‐spaces through which macrophages can penetrate and establish RGD links thereunder. Using graph theory, this study presents the example of mathematically modeling the functionality of extracellular‐matrix‐mimetic materials, which can help elucidate complex dynamics of the interactions occurring between host cells and materials via versatile geometrical nano‐engineering.
Anti‐Fatigue Cellular Graphene Aerogel Through Multiscale Joint Strengthening

Published: December 2024

AbstractDespite fatigue free of monolayer graphene, its assemblies, like cellular graphene aerogels (CGA), are usually suffering of frequent fatigue and inherent strength degradation in repeated loading. In this work, by employing multiscale modeling, the highly intrinsic anisotropic mechanical properties of the cell wall due to the layer‐by‐layer stacked graphene sheets are uncovered, which easily trigger the unique skeleton joints damage during repeated loading and contribute the primary fatigue mechanism of CGA. Conversely, multiscale joint strengthening strategies are proposed by interlayer crosslinking and joint curvation, improving the interlayer interaction, and decreasing interlayer stress during compression, respectively, so as to effectively suppress joint damage to improve fatigue performance of CGA. This work not only clarifies the underlying fatigue mechanism of 2D cellular materials but also highlights optimal design strategies for developing anti‐fatigue graphene cellular structures.
