To improve motorbike performance, simple modifications are often applied using an aftermarket Electronic Control Unit (ECU). However, scientific studies on this particular topic are still limited. Therefore, the purpose of this research is to examine the effect of the aftermarket Juken 5 ECU on the power, torque, emissions, and fuel consumption of the Yamaha R15-V3 bike. The results of the dynamometer testing showed that the motorcycle with the Juken 5 ECU experienced an average increase of 8.09 ± 1.30% in power and 7.79 ± 1.31% in torque, respectively, at 5500 – 11000 rpm. However, the concentrations of Carbon Monoxide and Hydrocarbon emissions also increased by 170% and 360%, respectively. Particulate emission measurements also revealed that the Juken 5 ECU usage resulted in a significant increase in particulate counts. Compared to the standard ECU, motorcycles equipped with the Juken 5 ECU produced 89% and 145% more particulates in the size range of 0.3 – 0.374 μm and 0.374 – 2.685 μm, respectively. The performance and emission data analysis results indicated that the increase in power and torque achieved by the Juken 5 ECU is simply due to more fuel being injected into the combustion chamber. This finding was supported by the results of fuel consumption testing, where using the aftermarket ECU increased motorcycle fuel consumption by 63.6%.

Sandiwch composite is a type of structural composite material composed of a strong facesheet and a low-density core material. Sandwich composites have a high mechanical properties with their lightweight structure, so this material can be applied to aircraft structures. This study aims to determine the mechanical properties of carbon fiber sandwich composite twill 3K/divinycelll foam with various fabrication methods. The fabrication methods used vacuum bagging methods, and vacuum assisted resin infusion method. Mechanical tests conducted are flatwise compressive with ASTM C364 standard, edgewise compressive with ASTM C365 standard, flexural three point bending with ASTM C393 standard, and tensile strength with ASTM D3039 standard. In addition, scanning electron microscope test were also conducted to determine the morphology of the surface of the material and the bond between the fiber and the matrix. The results were obtained that vacuum asssisted resin infusion method has the most optimum mechanical with a high value in each test, such as the result of flexural three point bending of 47,51 MPa is better when compared with the result of vacuum bagging method of 18,70 MPa. Scanning electron microscope test results also showed that the vacuum assisted resin infusion method has the best morphology with perfect bond between matrix and fiber. So that it can be concluded that the most optimal mechanical properties of sandwich composites are produced by vacuum asssisted resin infusion method.
John Franklyn Venner FCA: An Orthodox Chartered Accountant Working in an Unorthodox Organization
Authors: Piper Ian , McBride Karen , Tait Alan 
Published: September 2023

ABSTRACT
John Franklyn Venner was a chartered accountant and senior partner in an eminent City of London firm of accountants. However, between 1940 and 1945, Venner worked at the heart of the unorthodox and top secret Special Operations Executive (SOE), which was set up to facilitate clandestine warfare. Venner used the accounting orthodoxy of financial controls, the recording of transactions, and regular financial reporting to build a strong bond of trust and confidence with the Treasury and Bank of England. This provided space for Venner to develop unorthodox financing schemes, including black market foreign currency transactions, which generated millions of pounds of currency and made a major contribution to the war effort. Venner died in 1955 at age 52. This biographical microhistory, using archival sources, brings his story out of the shadows and demonstrates how an eminent chartered accountant navigated the unorthodox world of the SOE during the Second World War.
Data Availability: All data used are available from the public sources cited in the text, apart from the transcripts of the two James Venner interviews.

A proposed new definition of measurement uncertainty
Authors: Bich Walter 
Published: September 2023

A new definition of the measurement uncertainty (MU) was proposed by the Working Group 1 of the Joint Committee for Guides in Metrology, JCGM-WG1. This definition avoids any quantitative aspect of the measurement uncertainty and focuses on its subjective nature.
The proposed new definition reads as follows:
doubt about the true value of the measurand that remains after making a measurement.
Here, MU is no longer quantitative; it is rather a (subjective) state of mind. MU is the concept, and its quantitative measures, such as the standard measurement uncertainty, are different in nature. This separation greatly contributes to clarity.
Being defined as a state of mind, MU is subjective and reflects the belief of the experimenter in the result. There is no “true uncertainty” in nature to be estimated. There exists the measurand, and the uncertainty about its true value is a personal matter. Of course, the state of belief is based on objective data, and a good experiment is conceived in such a way as to minimise subjectivity. Yet, the hope to eliminate subjectivity from a measurement or from science at large is just a hope.
The proposed new definition explicitly uses the term “true value”. Perhaps, at the philosophical level, the concept can be questioned, whereas in the context of parameter estimation, the mathematics behind calculations needs a unique true value, which is ideally represented by a unique real number.
The doubt is about the unknown value of the measurand, not about the estimate. The estimate is viewed as a realization of a random variable describing the state of knowledge about the measurand. As such, the estimate is fixed and has no uncertainty. Randomness is in the variable, not in its realizations.
Dispersion analysis in colorimetric control

Published: September 2023

In the paper, solutions to the scientific and practical task of applying covariance analysis to determine the factor influence on the functional transformation of the control parameter in colorimetric research are considered. The research involves determining the factor influence on the additive and multiplicative components of the measurement error of the colorimetric control parameter to assess the reliability of conclusions about the factor influence on the transformation of the control parameter. Limits on the amount of the main level (control parameter) and factors affecting the result of colorimetric control are determined. During the study, the equations to assess the reliability of statistical conclusions about the informational significance of indicators of colorimetric control for a simplified model of cross-classification were obtained.
The need to carry out the research is related to the fact that during colorimetric control of grain crops, the uncertainty of the measurement results of the values of the controlled indicators is large enough, and so it must be evaluated. However, the proposed approach is not limited to a few colorimetric controls, but can be extended to a wider range of problems, where it is necessary to consider the factor influence with further ranking of factors by levels of significance.
About the definition of the terms “management” and “upravlinnya/keruvannya” in the DSTU ISO 9000 series of standards
Authors: Horopatskyi Viktor , Parakuda Vasyl , Sukhenko Anatoliy 
Published: September 2023

The issue of replacing the term “upravlinnya/keruvannya” with the term “management” in the DSTU ISO 9000 series of standards is considered.
The initiators of the replacement believe that the authors of the national standard DSTU ISO 9000:2015 Quality management systems. Fundamentals and vocabulary made erroneous translation of the term “management”, since the concept of “management” has a much broader meaning than the concept of “upravlinnya/keruvannya”, and this negatively affects the development of the Ukrainian economy. The initiators of the replacement insist on the immediate correction of this error in the DSTU ISO 9000 series of standards. To support these claims, the initiators have amassed numerous expert opinions, comments and other materials, the basis of which was the Russian-language edition of the ISO 9000:2015 standard, as well as long ago cancelled and replaced standards in the field of quality management. The reference to Russian-language publications is based on the fact that Russian is one of the three official languages of the ISO.
The proposed replacement of the translation of the term “management” in the standard DSTU ISO 9000:2015 Quality management systems. Fundamentals and vocabulary was analysed. The equivalence of the concepts of “upravlinnya/keruvannya” and “management” is substantiated. The examples demonstrating the erroneous interpretation of the concept of “management” are given. Complying with the requirements of 6.1.5 DSTU 1.5:2015 National standardization. Rules of development and presentation of national normative documents for the use of foreign words and terms in the presence of equivalent words and terms in the Ukrainian language is stressed.
The effect of the mantle and core matter phase state on the course of geodynamic processes
Authors: Usenko O.V. 
Published: September 2023

The study of the course of geodynamic processes in the lower crust and upper mantle proves that an additional energy contribution is made by a change in the phase state of matter with increasing pressure and temperature. The gas phase, composed of hydrogen, oxygen and carbon, turns into a fluid that combines the properties of a liquid and a gas. The result is a change in the behavior of fluid-crystal and fluid-melt systems which significantly accelerates melting and physicochemical interactions in the thermal asthenosphere. These conclusions are confirmed by numerous experimental studies and the results of the study of xenoliths representing the crust and mantle of cratons and active regions.
Seismic tomography studies show distinct patterns of inhomogeneities in physical pro­per­ties, reflecting inhomogeneities in the mantle structure. Many works hypothesize, with substantiation, that plumes or fluid flows arise at the boundary of the core and mantle and are factors of all geodynamic processes. Modern ideas about the composition of the Earth's core are based on the statement that it is composed of molten iron with minor impurities of other elements. However, calculations of the energy balance and physical modeling of the redistribution of matter in the core itself show that the removal of volatile components or convective currents do not provide enough energy for the formation of plumes.
The assumption that the substance of the core is an electrically conductive ionic liquid in which chemical compounds have completely dissociatedand the electronic structure has no gapradically changes the idea of the energetics of the core and the possibility of initiating plume processes. The properties of a substance in a similar phase state are fundamentally different from the properties of a liquid.

Published: September 2023

Abstract

Objectives
The objective of this study was to investigate the treatment effectiveness of long-term Bionator use on the craniofacial pattern, nasopharynx, oropharynx, hypopharynx, hyoid bone, and cervical vertebrae in patients presenting with a skeletal Class II malocclusion involving mandibular retrognathia.

Methods
A treatment group of 27 patients with a skeletal Class II malocclusion treated using a Bionator was compared with a control group of 27 patients presenting with a skeletal Class I malocclusion managed without Bionator treatment. The Bionator was worn in the subject group until the complete eruption of the second molars. Lateral cephalograms of the group before (T0) and after Bionator treatment (T1) were compared. A two-way analysis of variance and a paired t-test were applied for statistical analyses.

Results
A significant increase in the SNB angle and a decrease in the ANB angle were apparent in the Bionator treatment group. The dimensions of the oropharyngeal and hypopharyngeal airways and the hypopharyngeal area increased significantly. Conclusion Long-term treatment using a Bionator resulted in the advancement of a retrognathic mandible. In addition, the dimensions of the oropharyngeal and hypopharyngeal airways and the hypopharyngeal area increased significantly, reaching the same level as that of skeletal Class I subjects.

Published: September 2023

ABSTRACT
This paper describes research conducted on the polyphenolic compounds found in wine and different parts of the grapevine. The research consisted of two experiments. In the first, extracts of polyphenols from the leaves, stems, skins and seeds were measured. In the second, these parts were macerated and left in the must during fermentation. For this experiment, the Souvignier gris wine grape variety was used. In both cases, 33 polyphenolic compounds were measured. These measurements were made using the liquid chromatography–mass spectrometry (LC-MS) method. Based on the results, the individual concentrations of all the polyphenolic compounds in different parts of the plant were measured. Addition of the individual parts of the grapevine to the must during fermentation was shown to increase the concentration of the individual polyphenols in the wine. It is therefore important not to forget the importance of the stems and the maceration of the grapes during the winemaking process.

Today's the advancements of technology have an impact on many aspects of life, including health, education, transportation, business, information communication, and government administration. Nonetheless, given the strong relationship between technology and the military, technology advancements could lead to a war. The sheer proliferation of technologies implemented in military operations spawned technology-based warfare called cyber warfare. Cyber warfare refers to wars carried out through the virtual world and is coordinated with conventional warfare. In cyber warfare, opposing countries perform cyber operations through cyberspace as the latest weapon of warfare launched to destabilize the national security and stability of the target state. The current cyber warfare is in the international armed conflict between Russia and Ukraine. This article analyses the deployment of cyber warfare in international armed conflict from the international humanitarian law perspective, and it also investigates Russia's use of cyber warfare against Ukraine. The purpose of this article is to understand how international humanitarian law rules the use of cyber warfare in international armed conflicts, in addition to the way Russia employs cyber warfare against Ukraine. This article is normative law research which uses the statute approach with juridical-normative research method. The findings found that cyber warfare carried out within the framework of international armed conflict is subject to international humanitarian law and that its use is also restricted by the fundamental principles of international humanitarian law. The research also found that Russia's cyber warfare against Ukraine in an international armed conflict is against the principles of differentiation and proportionality.

Published: September 2023

Objectives:
In a tertiary care hospital in Northern India, we examined the demographic, biochemical, and clinical risk factors related to gender differences in COVID-19 patients who were hospitalized.

Materials and Methods:
The study was carried out in a hospital with tertiary care. In this retrospective comparative observational study the data was collected from march 2020 to end of COVID pandemic. Analyses were done on the n = 1068 individuals who were hospitalized during the study period.

Results:
There were 1068 individuals evaluated in the trial, with a male-to-female ratio of 2.3:1. Males and females had similar mean ages (55.84 vs. 55.44 years). Difference was found to be statistically significant in asthmatic boys and females (P = 0.01). In our study, a novel severity score (NSS) was utilized to forecast inpatient mortality in COVID-19 patients. NSS scores were higher for men (2.95) than for women (2.65), with P = 006. Under the categories “Expired,” “discharged against medical advice (DAMA),” and “Discharged,” all the criteria that have been previously analyzed were compared. Based on the number of comorbidities, there was a clear, significant difference between patients who were discharged, expired, and under DAMA, with a P = 0.001. Majority of patients with comorbidities that most frequently impacted the cardiovascular and respiratory outcomes.

Conclusion:
Studies conducted globally found that men experienced a higher rate of mortality. Our study also indicates that when the number of comorbidities rises, the death rate rises. Therefore, individuals with a larger number of comorbidities, such as hypertension, diabetes, coronary artery disease, and peripheral vascular disease, should exercise particular vigilance.

Authors: Lara-Olivas Jorge Armando , Sangrador-Deitos Marcos V. , Marian-Magaña Ricardo , Padilla-Leal Karen Elizabeth , Soto-Hernández José L. , Gomez-Amador Juan L. 
Published: September 2023

Background:
Fungal infections should always be considered in difficult-to-treat paranasal sinus conditions. Sphenoid fungal balls are characterized by the presence of dense fungal masses in the sinus cavity without invasion of surrounding tissues. This case emphasizes the importance of accurate terminology and management and also highlights the involvement of rare pathogens such as Drechslera hawaiiensis. Diagnosis is typically based on imaging studies and intraoperative findings. Accurate identification of the pathogen is crucial. Fungal infections of the paranasal sinuses, including fungus balls, can present challenges in diagnosis and treatment. D. hawaiiensis, although infrequent, can cause potential life-threatening infections.

Case Description:
We present a 26-year-old non-HIV male patient who presented with nasal symptoms and mild headaches. The patient underwent an endoscopic exploration that revealed a soft, grayish lesion with a buttery consistency. Gross total resection was achieved and the lesion was identified as being caused by D. hawaiiensis; thus, intravenous antifungal treatment was given.

Conclusion:
Endoscopic surgery remains the preferred approach for disease control. Considering alternative treatments and exploring novel approaches are essential in managing complex pathologies in neurosurgical practice.

Background:
The coronavirus disease 2019 (COVID-19) pandemic has caused significant structural changes in acute care hospitals. COVID-19-associated stroke has gained attention, with abnormal coagulation and vascular endothelial damage being recognized. While ischemic cases are commonly reported, hemorrhagic cases have also been reported. This report presents a case of ruptured vertebral artery dissection aneurysm associated with COVID-19, resulting in subarachnoid hemorrhage (SAH). The treatment course, challenges in managing cerebral vasospasm, and early recanalization achieved through endovascular therapy are described.

Case Description:
A 67-year-old male patient was brought to our hospital for emergency treatment of impaired consciousness that occurred while recovering from COVID-19. He underwent endovascular internal trapping using coils, and although the rupture did not recur, he required long-term tracheal management, which resulted in a cerebral infarction caused by cerebral vasospasm. In addition, early recanalization was seen, which required retreatment.

Conclusion:
This case highlights the challenges in managing COVID-19-associated SAH and emphasizes the need for infection control measures and proper postoperative care. Establishing protocols for detecting and managing cerebral vasospasm is essential.
