Authors: Cozac Dan-Alexandru , Amato Filippo , Savo Maria Teresa , Lassandro Eleonora , Cordoni Gabriele , Motta Raffaella , Pergola Valeria 
Published: September 2024

Abstract

Introduction
Aortitis includes both infectious and non-infectious inflammation of the arterial wall. Infectious forms have a worse prognosis, necessitating immediate diagnosis and treatment. We report a case of a patient with prosthetic valve endocarditis complicated with infectious aortitis and multiple embolic lesions, ultimately leading to death.

Case presentation
An 81-year-old man with an aortic valve bioprosthesis (Intuity 27 mm) presented with fever, dysuria, and ankle swelling. Laboratory showed leukocytosis, anemia, elevated NT-proBNP, and C-reactive protein. Echocardiography revealed a hyperechogenic mass on the bioprosthesis, confirmed as prosthetic endocarditis by transesophageal echocardiography, which also showed an aortic bulb aneurysm and a 9 mm arterial wall thickening. Blood cultures were positive for Staphylococcus aureus, and intravenous antibiotics were started. Thoracic computed tomography confirmed aortic root dilation and mural thickening, indicating infectious aortitis with multiple embolic lesions in the spleen and kidneys. The patient then suffered an intestinal sub-occlusion. The Heart Team decided against cardiovascular surgery due to frailty and high surgical risk. Despite initial hemodynamic stability, his condition deteriorated, leading to death.

Conclusion
This case presents a challenging scenario of prosthetic valvular endocarditis complicated by infectious aortitis, aortic aneurysm, and multiple thromboembolic lesions in a high-risk patient, ultimately resulting in death.

Knowledge and Anguish at Work: the Clinical Case of a Telephone Operator
Authors: Gomes Júnior Admardo Bonifácio , Santos Luciana Gelape dos , Cunha Daisy Moreira 
Published: October 2024

Objective: The objective of this study was to understand the meaning of mental symptoms manifested at work by articulating their material basis present in the work context and the subject's historical singularity.

Theoretical Framework: Psychoanalytic theory is used in this case study as a basis for understanding the relationship between knowledge and anguish at work. On the other hand, it is in ergology that we find the necessary theorizations for a reading of what affects the subject in tele-service work.

Method: This is a clinical case study based on the psychoanalytically oriented notes of a telemarketer with work-related symptoms.

Results and Discussion: As the main result, we read symptomatic production both as a response on a level of direct material causality to the inconsistency of the assumption of knowledge attributed to the trade and the value of work, and as a way out that the subject finds for their symptomatic position.

Implications of the research: We conclude that the orientation of the treatment must seek to preserve the assumption of knowledge in the subject and in their work and enable subjective and material accountability.

Originality/Value: This study contributes to the literature by combining psychoanalysis and ergology in the search for an understanding of illness at work. The relevance and value of this research is evidenced by the fact that it presents an original clinical case that seeks to highlight the relationship between the place reserved for knowledge in contemporary work and the symptoms produced by it.

Authors: Moreira Cândido Jorge Carvalho Peres , Terrinca Catarina Carvalho Peres , Cristóvão Domingos Custódio , Antão Mário Alexandre Guerreiro 
Published: October 2024

Objective: To observe the existence of a relationship between quality certification and performance and bankruptcy prediction for Portuguese SMEs.

Theoretical Reference: The search for quality and its certification, via the International Standard Organization (ISO), theoretically, is related to the going concern assumption, making it possible to enhance the company's economic and financial sustainability.

Method: Multisectoral Multivariate Discriminant Analysis (ADM) models, considered the most efficient, were selected for application, as well as the commonly used Univariate Analysis indicators. In Bureau Van Dijk's SABI Database, we collected Portuguese SMEs, with financial information from 2014 to 2018, certified in the scope of quality, ISO 9000 or 9001, on 12/31/2018, of these, we focused on those with main activity in NACE D - Electricity, Gas, Steam, Hot and Cold Water and Cold Air or G - Wholesale and Retail Trade, Repair of Motor Vehicles and Motorcycles as they are the most important. The Sector Average Company was also collected for the same NACE via Banco de Portugal Sector Tables. Then, having applied the models and indicators under study, we compared the results obtained between them, in order to observe the possible effect of quality certification on financial performance.

Results and Discussion: No implication of quality certification in improving or optimizing the performance or economic-financial position of entities is identified.

Implications of the Research: Uncover the influence of quality certification on the economic-financial position of companies, allowing for deeper investigation into bankruptcy, sustainability and value creation.

Originality/Value: The specificities of the sectors and business size, crises and increasing closures make it vital to identify what will influence performance and sustainability, as no studies have been identified on this topic, focusing on Portuguese SMEs, certified via ISO 9000 or 9001.
Introducing a Novel Initiative for Mitigating the Impacts of Road Mortality on Turtles in Brampton, Ontario Using 3D Printed Models: A One Health Perspective
Authors: Gillette Emilia , Zuniga Matthew , Tejada Rosa , Maalouf Justine 
Published: October 2024

With 7 out of 8 turtle species in Ontario classified as at-risk, vehicular-reptile collisions on roads pose a serious threat to turtle populations provincially. These species, however, play crucial roles in maintaining the health of humans, non-human animals, and the environment. By providing ecosystem services like nutrient cycling, population control, and pollination, turtles are essential in semi-aquatic ecosystems like wetlands. However, the need for road infrastructure to support human populations, failures in exclusion fencing and eco-passages, and the varied perspectives of numerous stakeholders make this issue particularly difficult to solve. Despite these challenges, a novel initiative taking place at Heart Lake Conservation Area in Brampton, Ontario may provide an alternative solution. Using 3D printed models, Toronto and Region Conservation Authority (TRCA), in partnership with the Brampton Library and Heart Lake Turtle Troopers, is attempting to reduce mortality along roads by leveraging knowledge about the nesting preferences of female turtles. From a One Health perspective, this novel initiative engages multiple stakeholders to create an interdisciplinary solution combining technology, art, and science to protect turtle populations in the region.

Сто лет тому назад в нашей стране произошли события всемирно-исторического значения, провозгласившие курс на преодоление фундаментального противоречия капиталистической формации между трудом и капиталом. Мир — хижинам! Война — дворцам! Ожидалось преодолеть его и в архитектурно-градостроительной сфере. Рабочие поселки периода индустриализации страны, новые социалистические города послевоенного периода, «голубые» города атомного проекта, целинные поселки и станции БАМа — свидетели всенародного подвига. В них население имело право и действительно получало бесплатное жилье, образование, медицинскую помощь и многое другое. Ресурсы страны собирались и перераспределялись с опорой на научные обоснования в строгом соответствии с идеологическими установками и социально-экономическими возможностями. Однако, довести этот эксперимент до черты, когда единство целей и задач народа и государства стало бы залогом их процветания и устойчивого развития, не хватило сил, политической воли и зрелости в отличие от Китая. Свернув на другую дорогу, мы вновь очутились в ситуации, когда первейшую потребность человека в жилище возможно осуществить ясным и понятным способом, но на кабальных условиях, то есть, тяжелой формы личной зависимости, связанной с займом. Звучит неприятно. Порочна и сама суть процесса, когда гражданин самой большой страны Земного шара все свои трудовые сбережения и проценты банковского кредита отдает примерно в равных долях на строительство и на возрастание капитала финансового олигархата. Естественно, что тот, кто отдал все, что имел, попав в кабалу, становится современным пролетарием, проживающим в городе, где ищет с утра до ночи и с ночи до утра возможность продать свой труд на приемлемых условиях. Он уже не олицетворяет нужду с образом конкретного хозяина. Нуждой становится сама жизнь в обертке фасадов кабальной архитектуры, разделенной на два полюса: многоквартирные дома экономкласса и роскошные апартаменты с домами хозяев жизни. Благодаря такому устройству, строительная отрасль стала одним из основных экономических локомотивов внутреннего развития страны, но главное противоречие вновь не преодолено. Напротив, оно расцвело пышным цветом, бросая отблески несправедливости на все стороны нашей жизни. Сегодня страна готовиться к выборам высшего должностного лица государства и люди думают, мечтают о справедливости, без ориентации на которую кабальная гримаса архитектуры никогда не сойдет с облика наших городов и сел.

Methods for generating magnetic and electric fields for ironless high-voltage pulse transformers
Authors: Пальчиков Е.И. 
Published: October 2024

В работе рассмотрены принципы формирования трехмерной конфигурации магнитных и электрических полей для мощных импульсных трансформаторов без применения ферромагнитных сердечников. Для формирования магнитных полей предлагается применять проводящие оболочки толщиной большей скин-слоя. Такие оболочки, названные скин-экранами, выравнивают магнитное поле и поток вдоль вторичной обмотки, позволяют раздельно формировать электрические и магнитные поля в объеме трансформатора, увеличивают коэффициент связи между обмотками, позволяют согласовать магнитное и электрическое поля таким образом, что на витках высоковольтной вторичной обмотки отсутствует заряд. Это предотвращает межвитковые пробои, увеличивает коэффициент полезного действия трансформаторов и делает их компактным.
The paper considers the principles of forming a three-dimensional configuration of magnetic and electric fields for high-power pulse transformers without the use of ferromagnetic cores. For the formation of magnetic fields, it is proposed to use conductive shells with a thickness greater than the skin layer. Such shells, called skin screens, align the magnetic field and flow along the secondary winding, allow the electric and magnetic fields to be formed separately in the transformer volume, increase the coupling coefficient between the windings, and allow the magnetic and electric fields to be matched in such a way that there is no charge on the turns of the high-voltage secondary winding. This prevents inter-turn breakdowns, increases the efficiency of devices (transformers) and makes them compact.
development of selective methof for synthesis of bis(carbohydrazone)glyoxal
Authors: Глухачева В.С. , Ильясов С.Г. 
Published: October 2024

Рассмотрено несколько реакционных подходов, к синтезу ранее неизвестного бис(карбогидразон)глиоксаля. В том числе изучены реакции нуклеофильного замещения и переиминирования. Показано, что при переиминировании глиоксима карбогидразидом селективно образуется линейный бис(карбогидразон)глиоксаля, а при нуклеофильном замещении бис(нитросемикарбазон)глиоксаля гидразин-гидратом происходит щелочной гидролизу с выделением карбогидразида. Дальнейшая конденсация бис(карбогидразон)глиоксаля с глиоксалем ведет к количественному получению моноциклического 1,2,4,5,8,9,11,12-октаазациклотетрадека-5,7,12,14-тетраен-3,10-дион. На сегодняшний день это единственно возможный метод синтеза бис(карбогидразон)глиоксаля. т.к. прямой конденсацией карбогидразина с глиоксалем возможно получение только моноциклического продукта.
Several reaction approaches for the synthesis of never-before-seen bis(carbohydrazone)glyoxal were undertaken herein. The reactions of nucleophilic substitution and the transamination were explored as well. The transamination of the glyoxime with carbohydrazide was shown to yield a linear bis(carbohydrazone)glyoxal, whereas the nucleophilic substitution of bis(nitrosemicarbazone)glyoxal by hydrazine hydrate resulted in alkaline hydrolysis to liberate the carbohydrazide. The further condensation of bis(carbohydrazone)glyoxal with glyoxal led to a quantitative liberation of monocyclic 1,2,4,5,8,9,11,12-octoaxazacyclotetradeca -5,7,12,14-tetraene-3,10-dione. To this date, this is the only possible method for the synthesis of bis(carbohydrazone)glyoxal because the direct condensation of the carbohydrazine with glyoxal gives only the monocyclic product.

Published: October 2024

В статье представлена разработка нового метода получения N, N’–дибензилмочевины взаимодействием N, N’–динитромочевины с бензиламином в зависимости от температуры реакционной смеси. Изучались два пути синтеза: I путь – получение N,N’–дибензилмочевины через выделение и изучение промежуточных продуктов реакции и выдерживание определенного температурного режима; II путь – без выделения промежуточных продуктов реакции. В качестве промежуточных продуктов были выделены бензиламинная соль и монозамещенная бензилнитромочевина. В процессе исследований выявлено, что получение N, N’–дибензилмочевины без выделения промежуточных продуктов позволило сократить время реакции и увеличить выход. Исследование конечных продуктов реакции, полученных двумя путями показано, что ИК, 1Н ЯМР-спектры и температура плавления совпадают с литературными данными, что подтверждает идентичную структуру обоих образцов.
Abstract – This study develops a new method for the synthesis of N, N’-dibenzylurea by reacting N, N’–dinitrourea with benzylamine, depending on the reaction mixture temperature. Two synthetic pathways were under study: pathway I – synthesis of N,N’–dibenzylurea via the isolation and characterization of the reaction intermediates, and maintenance of certain temperature conditions; pathway II – without isolation of the reaction intermediates. The isolated intermediates were benzylamine salt and monosubstituted benzyl nitrourea. The studies revealed that the preparation of N,N’–dibenzylurea without isolating the intermediates allowed the reaction time to be shortened and the yield to be increased. Characterization of the reaction end-products resulted from the two pathways showed that the IR and 1Н NMR spectra and melting point are consistent with the literature data, corroborating that the both samples are identical in structure.
