This structural valuation in oblique equivalent waves has as a study case a large LNG liquefied natural gas carrier,
with an overall length of 289.3 m, structural gas membrane tanks, and a double hull. From the operation load cases, for the
numerical study, a selection of the main cases is made, full cargo and ballast. The selected oblique design wave conditions are
specific to unrestricted navigation areas, sagging and hogging wave-free surface, with the heading angle covering the oblique
relevant cases. The computation of the LNG carrier equilibrium in oblique design waves is done by a three-parameter nonlinear approach, with the own P_QSW software. The 3D-FEM large LNG carrier model is developed by Femap/NX Nastran
software. The structural valuation in oblique design waves, by strength and freeboard criteria, of the large LNG carrier
involves 3D and 1D models. For practical purposes, the strength valuation results are synthesized as polar diagrams, for the
relevant heading angles of the oblique design waves, representing the wave height safety limits for preserving the large LNG carrier structural integrity.

For driving belt condition monitoring, the main interest is the certification of the capacity to keep their qualities unchanged over a long period of time and secondary to detect the imminence of the catastrophic failure. This paper presents a study on the behaviour detection and description of a flat driving belt health condition, used in a rotary machine electrically driven, particularly a lathe headstock gearbox running idle. It was discovered that in the mechanical power transmitted from electromotor to gearbox via a flat belt some specific sinusoidal components (a fundamental and some harmonics) of variable power are generated. The description of these power components (by values of amplitude, frequency and phase at origin of time) is indirectly detectable in the evolution of the active electrical power absorbed by the drive electromotor. Two arguments are available for this approach. Firstly, there is a reasonable assumption that between the mechanical power and the active electrical power there is an approximated proportionality relationship through the power efficiency. Secondly, the evolution of the active electrical power (or mechanical power as well) is a deterministic signal with a low level of noise. A simple computer assisted procedure of active electrical power signal acquisition and data processing was conceived, the detection was done by computer aided curve-fitting procedures in Matlab applied on active electrical power evolution absorbed by the driving motor in stationary working regimes (the electromotor playing the role of a mechanical power sensor). Mainly two ways of graphic representation have been proposed in order to describe the variable power generated by this flat belt (in time and frequency domains). The behaviour of many other types of belts involved in rotary machines driving can be similarly described.

: The performed investigations concerned on the effect of cold rolling on the corrosion behavior and microstructure of austenitic AISI 301 stainless steel. Samples of steel strip were cold-rolled within the degree of deformation 30%, 50% and 80%. The corrosion resistance test was examined using gravimetric and potentiodynamic method. Corrosion tests were conducted in acidic and alkaline corrosive environments. A light microscope and a scanning electron microscope were used to observe the surface morphology of the samples after corrosion testing. Corrosion tests by gravimetric method showed that investigated steel is not resistant to corrosion in 0.5N H2SO4 solution, while no significant weight loss was observed in artificial seawater solution (0.5N NaCl). Based on potentiodynamic tests carried out in 0.5N NaCl solution, it was found that the pitting corrosion resistance of the tested cold-rolled steel AISI 301 decreases with an increase in the degree of plastic deformation in the range of 30% to 80%. However, a decrease in the corrosion potential and an increase in the current density were observed on the polarisation curves. The propensity of the steel to initiation and propagation pitting was found to increase both with increasing degree of deformation and the associated increase in the volume proportion of martensite- in the material structure. The occurring of martensite- ’ in the investigated steel was confirmed by X-ray methods.

In recent years, detecting defects in materials has become an important element in many industries, such as automotive, construction, textile manufacturing, and many others. Material defects, such as stains, cracks, dents, and others, can affect the quality and durability of the product, which can have serious consequences for safety, performance, and product quality. Therefore, it is important to detect and remove material defects as quickly and accurately as possible. Traditional methods of detecting material defects, such as manual inspections or simple visual algorithms, can be unreliable and, above all, time-consuming. In recent years, however, new tools based on intelligent algorithms (Liu et al., 2023) or structures (Neethu et al., 2015), such as neural networks, have emerged that enable automation and significantly increase the precision of defect detection. One of the most popular tools for object detection is the YOLOv5 (Redmon et al., 2016) (You Only Look Once version 5) model, which is based on neural networks and designed for fast and accurate object detection in images. The YOLOv5 model can be trained to detect specific types of material defects, such as stains, cracks, dents, etc. To use the YOLOv5 model for defect detection in materials, images of the material with specified objects of interest are needed, which will be used as input data for the model training. The YOLOv5 model analyses the images and determines rectangular frames around each defect indicating its location, and then assigns a selected label (in this case, the name of the defect). As a result, the YOLOv5 model is able to detect defects in new material images, regardless of their location, colour, and size. As the work progresses, it is also possible to prepare new images and retrain the model for new defects or to improve the performance of existing ones. As a result of the research, the obtained results at a 95% level of recognized defects certainly qualify the applied technology for professional use after appropriate workstation preparation and a sufficiently large amount of data (preferably 1000 or more).

The investigation presents the evolution of texture and microstructure of cold-rolled austenitic AISI 301 stainless steel sheets. The austenite steel was deformed by cold-rolling to 30%, 50% and 80% of rolling reduction. It was found, that during cold plastic deformation, phase transformation of austenite into martensite takes place. The transformation progress was confirmed by the microscopic investigation, as well as by X-ray diffraction methods. Texture analysis was performed on the basis of the orientation distribution functions (ODFs) calculated from the experimental pole figures. The texture of the deformed austenite is dominated by fiber orientations α =110║KN, mainly Goss orientation {110}001 and alloy type orientation {110}112. On the other hand, plastic deformation-induced martensitic transformation of the type (γ') significantly affects the development of martensite texture ' in the cold rolling process. After rolling with a 30% of deformation degree in the texture of  martensite, the strongest orientation is {001}110, while after maximum deformation (about 80%), the {111}112 and {112}110 type orientations dominate. It was found that in AISI 301 steel structure after deformation range from 30% to 80% proportion of α’ martensite phase changes from about 26.7% to about 67.8%.

Published: January 2024

The RE band of electromagnetic radiation has recently become the subject of interest in remote sensing due to its greater penetration into the plant structure than the commonly used NIR band. It is particularly important in cultivating corn, which is characterised by considerable thick foliage during the growth period. While sensors equipped with this channel are used in satellite remote sensing and onboard drones, they are not implemented in airborne imaging systems. An airborne remote sensing station was constructed, including, in addition to the traditional R, G, B and NIR image components, also the RE channel and a laser scanner (ALS). Data processing involves geometric calibration and the creation of a multi-channel orthophoto map. The data processed in this way was tested by analysing several series of aerial recordings of a corn field, which involved developing interpretation keys based on selected vegetation indices and assigning individual groups of pixels with five plant health classes. This study focused on the comparative assessment of the effects of using the NDVI, GNDVI, NDRE and SAVI indices, comparing their results to yield measurements (CHM) and the results of field measurements of plants at the end of the growing season. Promising results with a high degree of correlation were obtained.
HERMENÊUTICA CONTRATUAL: REMEMORANDO A RUPTURA DO PARADIGMA PRINCIPIOLÓGICO LIBERAL
Authors: Chornobai João Vítor Ladeira
Published: January 2024

A matéria referente à regulamentação dos contratos é sensível por toda sociedade, vez que cada indivíduo está em constante submissão aos seus efeitos. Por tal razão, o Direito constantemente lança mão de institutos que garantam a sua integridade, entre eles, os princípios que o vinculam. Tais princípios, conduzidos pelas alterações propostas pela convergência que se dera entre o texto constitucional e o Código Civil, passaram por processo de notória remodelação, à qual ainda hoje nos sujeitamos. Assim, necessário é que se rememore e – substancialmente – que se compreenda, de modo abrangente, o panorama dos contratos e os princípios que a eles remontam, especialmente no exercício da hermenêutica que em relação a eles se opera. Para tanto, desenvolve-se pesquisa teórica, à luz do método dedutivo, por meio do qual são analisados os conceitos relativos à disciplina legal dos contratos, à hermenêutica que a tal tema se dedica e à cadeia de princípios que os conduzem, levando-se em conta as produções doutrinárias e as incidências legais. Para tanto, faz-se uso de documentação indireta (revisão bibliográfica e legal), analisando-se parcela da legislação atinente ao tema e, especialmente, os estudos clássicos produzidos e consolidados sobre o objeto de análise, que permitam remontar à ruptura de paradigma que outrora se operara.

Published: January 2024

Objective: There has been a trend toward percutaneous tracheostomy in recent years, as anesthesiologists have been interested in this and learned the techniques. We aimed to investigate the perspectives of anesthesiology and reanimation specialists in our country regarding tracheostomy. Methods: A survey was conducted on Anesthesiology and Reanimation specialists, which included questions of tracheostomy experience, preferences. Chi-square or Fisher tests were used for analysis. Results: A total of 213 people (51.2% women) participated, where 29% preferred tracheostomy within the two weeks of intubation, while 66% preferred it later. While 87% of the participants preferred percutaneous tracheostomy, 11% preferred surgical technique. For the specialists who preferred tracheostomy within the first two weeks of intubation, the rate of working in a university hospital was significantly higher (p=0.034). Of those who preferred surgical tracheostomy 91.3% had 0-10 times tracheostomy experience. While 89% of the participants preferred needle, 7% preferred scalpel cricothyrotomy. Conclusion: Tracheostomy is a commonly used procedure by anesthesiologists and intensivists. Bronchoscopy and ultrasonography are frequently used auxiliary tools. University hospital physicians often prefer tracheostomy within the first two weeks of intubation. Those with more tracheostomy experience mostly use the percutaneous method. Contrary to the current guidelines, needle method is preferred for cricothyrotomy in our country. Keywords: Complication, experience, percutaneous, surgery, tracheostomy

Published: January 2024

Background;

 Traumatic dental injury (TDI) has grown to be a significant public health issue due to its high prevalence as well as the significant negative effects it has on quality of life. This study aimed to examine the prevalence and causes of TDI in a  Dental outpatient clinic for 4 years.

Method:

A retrospective study was conducted on 52 TDI patients who were treated at a Tertiary Institution's Dental Outpatient clinic between June 1, 2017, and June 1, 2021.

 Data on age, gender, etiology, types of teeth involved, types of dental trauma, the day the incidents occurred, and treatment options were retrieved. Traumatized teeth were classified using Andreasen’s classification. Statistical analysis was carried out using SPSS version 20.0.

Result

 

A total of 208 patients with maxillofacial injuries (163 males and 45 females) aged 1 to 81 years were examined. The prevalence of TDI was 25%. Male and female prevalences were 18.2% and 6.7%, respectively. There were 52 TDI patients  with a mean age of 16.5  ±  12.02.

The most common reason for TDI was motorcycle accidents at 30.77%. Avulsion(40.67%) and subluxation(50%) were the most frequently diagnosed injuries in the permanent dentition and primary dentition, respectively. There was no association between trauma source and dentition type (p=0.342), nor was there a difference between trauma source and gender(p=0.863).

Conclusion.The study observed that a high percentage of 40.38% had an injury to three or more teeth resulting in attendant functional and esthetic complications. Hence public health issue that warrants urgent government attention.

Published: January 2024

Ultrasound imaging is an important tool in healthcare, used for screening, diagnosis, monitoring, and treating diseases. It works by using sound waves to generate images based on echoes reflected back from the object being examined. Advancements in ultrasound technology have made it more accessible to other healthcare professionals, resulting in its expanded application across all fields of medicine. In Zimbabwe, radiographers play a crucial role in providing ultrasound services, helping to address the shortage of radiologists, and improve patient access to quality imaging. However, there is a lack of available literature on ultrasound imaging human resources in Zimbabwe. This article reviews the historical development of ultrasound training for radiographers in Zimbabwe, highlighting the challenges and opportunities associated with their expanded role in ultrasound. It also emphasizes the benefits of involving radiographers in ultrasound services, such as improved patient care, cost savings, utilization of their knowledge and skills, and enhanced job satisfaction. The paper provides recommendations for the future, including the need for clear clinical leadership, specialized ultrasound programs, and continuous professional development (CPD) activities to ensure high-quality ultrasound services in the country. The insights presented aim to inform policy decisions and promote equitable access to essential ultrasound imaging in the Zimbabwean healthcare system.

Published: January 2024

Background: Cassia abbreviata plant extracts are used traditionally to treat various ailments including diabetes mellitus. However, very few animal studies have been conducted to investigate potential hypoglycaemic effects locally. We examined phytochemicals, median lethal dose and effects of Cassia abbreviata extracts and fractions on oral glucose tolerance in non-diabetic male Wistar rats.

Methods: Qualitative and Lorke’s methods were used to screen for phytochemicals and acute toxicity testing. Rats weighing 160 - 250 g were divided into 4 groups of 3 rats (phase one) and 4 groups of 1 rat (phase two) each for acute toxicity. Main experiments comprised 8 groups (extracts) and 7 groups (fractions) of 6 rats per group. Doses of 762 mgkg-1, 381 mgkg-1, and 190 mgkg-1 for extracts, 381 mg.kg-1 for the fractions, 10 mg.kg-1 for sitagliptin and 10 mL.kg-1 of vehicle were administered. Thereafter, blood glucose levels were assessed using Accu-Chek glucometer.

Results: Leaf methanolic extract and ethyl acetate fraction contained more phytochemicals. Acute toxicity test revealed no mortality in all the groups except for leaf ethanolic and methanolic crude extracts in phase two at dose 5000 mg.kg-1. Root bark ethanolic extract 381 mg.kg-1 showed significant hypoglycaemic effect at 60 min and 180 min while 381 mg.kg-1 n-hexane fraction showed significant hypoglycaemic effect only at 180 min. Sitagliptin 10 mg.kg-1 minimally reduced the blood glucose levels at 60 min.

Conclusion: More phytochemicals were observed in leaf methanolic extract and ethyl acetate fraction. Both extracts and fractions were considered practically non-toxic following acute toxicity testing. Root bark ethanolic extract and n-hexane fraction revealed better hypoglycaemic effects. Hypoglycaemic bioactivity observed may be due to various mechanisms.

Ранения шеи с повреждением магистральных сосудов (сонные артерии или яремные вены) могут сопровождаться массивным кровотечением и приводить к смерти. Производилась оценка эффективности наложения жгута на шею. При помощи УЗИ диагностики выполнена оценка кровотока в бассейне общей сонной артерии. Установлено, что при наложении жгута кровоток в лицевой артерии значимо не менялся, что может свидетельствовать о неэффективности наложения жгута при кровотечении из сосудов шеи

При вирусных инфекциях у детей поражение сердца и его проводящей системы возможно, как в остром периоде, так и при хроническом течении болезни. Наибольшей кардиотропностью обладают энтеровирусы – поражают миокард в 5–15% случаев. Длительное персистирование герпес-вирусов в организме является одной из причин развития дилатационной кардиомиопатии, коронарного васкулиста и нарушения ритма сердца. Поражение сердечно-сосудистой системы также возможно при заболеваниях, обусловленных вирусами гриппа, полиомиелита, Эпштейна Барр, гепатита. При этом осложнения и функциональные нарушения со стороны сердечно-сосудистой системы возникают независимо от возраста [2]. Резюме. Данный клинический случай свидетельствует о сложности клинической диагностики и важности более раннего применения инструментальных методов для выявления патологии сердца у детей при COVID 19. Наблюдение за детьми и подростками, перенесшими COVID-19 инфекцию, должно быть обязательно, так как многим из них требуется комплексная медицинская помощь, с необходимостью оптимизации стратегических подходов к оценке постковидного состояния у этих пациентов для разработки моделей реабилитации и профилактики осложнений
СРАВНИТЕЛЬНАЯ АКТИВНОСТЬ КАРБАПЕНЕМОВ (БИАПЕНЕМ/МЕРАПЕНЕМ) В ТЕРАПИИ КАРБАПЕНЕМАЗОПРОДУЦИРУЮЩИХ ENTEROBACTERALES
Authors: Доев Д.П.
Published: January 2024

Карбапенемные антибиотики по прежнем занимают лидирующую позицию в лечении назокомиальной инфекции. Однако начиная с середины 2000- х годов значение этой группы антибиотиков начало постепенно снижаться из-за распространения резистентности, прежде всего, обусловленной продукцией бактериями ферментов карбапенемаз [1,2]. В Российской Федерации на сегодняшний день доминируют NDM- и ОХА-48-типы карбапенемаз [4]. Согласно литературным данным активность карбопенемов отличается в зависимости от продуцентов карбопенемаз бактериями. Целью настоящей работы была сравнительная оценка активности биапенема, меропенема в отношении представителей Klebsiella pneumonia- 6 изолятов и Escherichia coli -3 изолята продуцирующих карбапенемазы. Материал и методы исследования. Определение чувствительности к биапенему и меропенему проводилось референтным методом микроразведений в жидкой питательной среде в соответствии с ГОСТ Р ИСО 20776-1-2010 с определением минимальной подавляющей концентрации (МПК). Детекция генов карбапенемаз КРС/OXA-48 и NDM проводилась с помощью набора реагента «ДНК-сорб-В» АмплиСенс. Результаты исследования: сравнительный анализ меропенема/биапенема, показал, что Enterobacterales (Klebsiella pneumonia и Escherichia coli) продуцирующие карбапенемазы NDM, OXA-48 проявляли бо́льшую чувствительность к биапенему, чем к меропенему. Причина выявленных различий в настоящее время не известна, возможно биапенем более устойчив к гидролизу карбапенемаз по сравнению с другими карбапенемами

Cloud computing has been widely adopted as the next-generation digitisation model for transforming the organisation into an entity that drives development and innovation. Nowadays, users of computing systems aim to get quick access to the virtual ecosystem and a new experience in cyberspace that seamlessly integrates with the existing services they use today. From the perspective of the military organisation/Military Enterprise, the cloud provides services for users and structures in a scalable, highly reliable and highly available manner, specifically with different security levels associated with the individual profile and functional roles in the organisation. From the end user’s perspective, the cloud provides a simple model for accessing information technology/IT services without the need for the human factor to fully understand the transport/transmission infrastructure and technology used. This article explores how modern military-classified and unclassified cloudnative infrastructures can be secured and managed in a national, military private, or mixed hybrid deployment cyber environment, along with various requirements and considerations for adapting cloud-native applications for military systems. In context, the article provides a simple but comprehensive introduction to the cloud native overview and the major technologies that developers use to build such reliable environments in cyberspace that could be the subject of a feasibility study to implement the concept of hybrid cloud in cyberspace with military use. The material is intended for IT experts, DevOps engineers, CIS (Communications and Information Technology) systems and infrastructure architects, cloud enthusiasts, cloud security experts, and any military professional involved in the development, migration, deployment, and management of current services and operations. of a cloud-native system.
Ucraina și praxisul Federației Ruse în materie de cuceriri teritoriale
Authors:   Universitatea din București, STAN Mircea
Published: January 2024

The hypothesis of the article is that the Russian Federation has developed a praxis in terms of territorial conquests, based on historical reminiscences,
and it will not be renounced, especially in the case of Ukraine. By immersing in history, without making it a determinant of the present and without showing psittacism, we believe that the assertiveness of the Russian Federation in its proximity can be justified only from its point of view. The brutal and completely illegal intervention in Ukraine is an example of reality violation. The end of communism and the dissolution of the USSR have generated
resentment among the Russians, which denotes capitulation. The Russians have probably rejoiced for a while over the end of totalitarianism, but they
have constantly regretted the loss of the empire. The “Russian world” is, in fact, nothing but a form of virtual restoration of the Soviet empire, a trap of the
past, in the souls and minds of the Russians, a ferment whose purpose is the internal destruction of the states that emerged after the collapse of the USSR, preventing them, by injecting feelings of confusion and nostalgia, to overcome the post-Soviet stage.
Dezvoltarea formațiunilor multinaționale în context european – determinări conceptuale și rațiuni practice de generare a capabilităților de apărare prin inițiative de cooperare regională –

This study aims to analyse the contribution of regional cooperation formulas in generating multinational formations that may be subject to participation in crisis management operations. From a chronological perspective, the development of formats of interaction in the field of defence were initiated in the period immediately following the Second World War, having as dominant reasons the creation of an efficient defence system to counter the Soviet threat. The criteria underlying the emergence of such formats undoubtedly concerned historical experience and affinities between European states, reinforced by the advantages of using geographical proximity in the development of joint programmes with immediate military applicability. On those coordinates, the regional dynamics recorded significant developments in the following decades, most of the initiatives being connected to varying degrees to the defence effort carried out in the context of NATO and the Western European Union (WEU). The end of the Cold War and, subsequently, the reorientation of multinational defence cooperation in support of crisis management efforts brought new challenges and opportunities for the optimization of regional interaction formulas. Most of them were focused on capitalizing on the results recorded in the operational contexts of the period, through which the structures generated through the regional cooperation were tested in demanding operational environments, offering validations for the continuation of this type of interaction and the consolidation of their permanence. Under those auspices, the launch of the European Security and Defence Policy provided an additional opportunity to exploit the potential of regional cooperation formats. Basically, they proved to be a link between the potential developed under the aegis of the WEU and the process of creating the EU profile in the field of security and defence. Regional cooperation initiatives must also be seen as an essential provider of forces and capabilities to support the objectives adopted by the EU in the context of defence cooperation. This trend has intensified as the European defence project has advanced, offering consolidated prospects for upporting this endeavour.
Ecouri ale golgotei bisericii ortodoxe din regatul României în Episcopia Buzăului (1916-1918)
Authors:   Universitatea Națională de Apărare „Carol I”, NEAGU Constantin
Published: January 2024

Between December 1916 and November 1918, approximately 66% of the territory of the Kingdom of Romania, including Bucharest, its capital, was under the domination of the Central Powers.
This academic approach certifies the fact that the Orthodox Church in the Kingdom of Romania was not exempted from the major trials experienced, during that period, by the population and the other institutions of the state.
It highlights some relevant aspects of the “Golgotha” suffered by some hierarchs, clerics, monks and believers, who lived through this unfortunate chapter in the national history.
Those “crucified” by the terror practiced by the occupying enemy continued to believe in the resurrection of the Romanian nation. Strong echoes of the temptations, passions and hopes of this capital moment
for our existential destiny were also fully felt in the Bishopric of Buzău, chosen as a case study.
