Ultrasound Findings in Median Arcuate Ligament Syndrome
Authors: Raimi Wasiu
Published: September 2024

Median arcuate ligament syndrome, which is often associated with abdominal pain, vomiting, and weight loss is an unusual disease caused by extrinsic compression of the celiac artery (CA) by the median arcuate ligament. Such tension on the CA increases the chance of geometric distortion.

This is a case of a 69-year-old female with abdominal pains. Ultrasound revealed cyclical CA geometric and Doppler changes. At deep expiration, CA bends and then gradually became tortuous with a 130° trunk deflection. At this phase, Peak systolic velocity (PSV) and celiac/aortic ratio measure 287cm/s and 4:1 respectively. There is also post-stenotic flow turbulence. However, during full inspiration, the CA deflection straightens out. As a result, the PSV decreases (167 cm/s) while the flow turbulence disappears. A clearer mechanism of CA compression with the resultant hemodynamic effect is demonstrated in this case.
Zinner Syndrome: The Role of Abdominal, Scrotal and Transrectal Sonography
Authors: Anwar Sohail , Dénommé Linda
Published: September 2024

Zinner syndrome is a rare, male congenital anomaly that becomes symptomatic in the second to third decade. Ultrasound is the gold standard for the diagnosis of this congenital malformation since the triad of findings of renal agenesis, dilated epididymis tubules and seminal vesicle cysts are easily identifiable on a transabdominal, pelvis and scrotal ultrasound. Since this anomaly presents in the reproductive stage ultrasound is optimal since its not known to have any bioeffects and is non-invasive.
Fetal Kidney Length as an Independent Estimator of Gestational Age: A Cohort Study of a Population of Yoruba Women in Lagos Nigeria
Authors: Eze Dr. Cletus Uche , Upeh Ernest Ruto , Olowoyeye Dr. Omodele A.
Published: September 2024

Background:

Fetal kidney length (FKL) can be used to estimate gestational age (GA) yet there is a paucity of data on its precision.

Aim:

To determine the precision and usefulness of FKL as GA predictor.

Methods:

In the prospective study, sonographically measured FKL was used to estimate GA while its standard error as GA estimator was calculated.

Result:

The rate of kidney growth was 1.2 mm per week; mean FKL was 37.7 ± 2.9 mm. The mean right and left FKL was 37.5 ± 3.6 mm and 37.9 ± 3.1 mm, respectively. Correlation between GA and FKL was positive (r = 0.9870; p < 0.0001); FKL was more precise than the biparietal diameter and abdominal circumference as GA estimator (standard error of estimation = ±6.6 days).

Conclusion:

Sonographically measured FKL was precise and useful as an independent GA estimator in the third trimester of pregnancy in a population of Yoruba women in Lagos Southwest Nigeria.
Strain Imaging in Echocardiography Part 2 of 3: Sonographer Initiatives and Imaging Protocol
Authors: Thampinathan Babitha , Ju Na Marcello Seung , Lam Jennifer
Published: September 2024

As the clinical utility of echocardiography grows, more emphasis has been placed on cardiac sonographer initiatives to implement and perform strain imaging as it can add diagnostic value and provide benefit when evaluating myocardial function. These include:

• Sensitivity and specificity to detect early myocardial changes

• Additive to LV function quantification

• Recognize distinct patterns displayed by Bull's-Eye plot correlating to a particular pathology

As strain echocardiography is a sensitive measure for left ventricular function, cardiac sonographers must spend time optimizing image acquisition and post-processing to ensure the reported global longitudinal strain values are accurate and reproducible. Before this stage, it is important to understand the fundamental concepts involved in strain imaging. This can be reviewed in part one of the strain imaging in echocardiography series. This second section of this 3-part series will review and provide guidelines for image acquisition, optimization, analysis and post-processing of data. This includes discussing clinical, technical and operator limitations that may provide challenges when performing strain imaging.
Strain Imaging in Echocardiography Part 3: Cardiac Pathology and Patterns of Strain
Authors: Thampinathan Babitha , Ju Na Marcello Seung , Lam Jennifer
Published: September 2024

INTRODUCTION

With the recent advances in cardiac imaging, echocardiography remains as one of the most reliable and cost-efficient non-invasive tests when assessing left ventricular function. Strain echocardiography provides comprehensive and valuable information on subclinical left ventricular (LV) systolic dysfunction that would be otherwise be missed on visual LV ejection fraction assessments. The final section of this three-part strain imaging series will review the clinical application of strain, primarily focusing on indications and pathology where cardiac sonographers should be considering performing strain imaging. Prior to this stage however, it is important to understand the foundational concepts involved in strain imaging, image acquisition and post processing techniques which can be reviewed in part one and two of the strain imaging in echocardiography series.

Published: September 2024

A high proportion of focal liver lesions are detected using ultrasonography. Many of them have characteristic sonographic appearances and can be diagnosed confidently in association with an accurate clinical history. Others require confirmation with computed tomography or magnetic resonance imaging. Contrast-enhanced ultrasonography has an increasing role in assessing these lesions. Typical and atypical features are described in this article, and correlative imaging is discussed.
Use of Sonography in the Diagnosis of Developmental Dysplasia of the Fetal Hip
Authors: El-kasheef Rua
Published: September 2024

Historically, plain radiographic film examinations were the norm for diagnosing developmental dysplasia of the hip (DDH); but today, sonography has also proven to be a safe and effective alternative (before the bones have ossified) to using plain film. This article outlines important features of DDH, such as risk factors and clinical signs, along with a look at the Ortolani and Barlow stress manoeuvres done by physicians for DDH screening. The unique ability of sonography to mimic these manoeuvres during examinations is outlined, along with the steps to completing an ultrasound examination for DDH. The differences between the European and Canadian protocols are also noted. Furthermore, the important anatomy of the fetal hip is explained, along with its normal and abnormal appearances. During diagnosis, the severity of the condition is now determined using the Graf classification system, which is outlined. Because sonography has become the primary diagnostic tool for DDH, it is important to be familiar with the proper methods needed for screening. Due to the vast abundance of research done on DDH, this article focuses on key information most relevant to sonographers.

An Unusual Cause for Intersection Syndrome
Authors: Li Tony Y.
Published: September 2024

Intersection syndrome is a rare local inflammatory disorder of the dorsal distal forearm at the cross point between the first compartment and the second compartment. The most common pathological change is the tenosynovitis of the second compartment at the intersection. It is usually related to acute or chronic overuse of the upper extremities, which may cause constant friction between the two compartments leading to synovial sheath injury and followed by inflammation. This case of intersection syndrome is induced by physical blunt injury. One feature of this case is that the inflammatory condition involves not only the second compartment, but also the first compartment. Another feature is that the tenosynovitis of the second compartment extends down to the wrist. Based on this case and literature review, another mechanism for the syndrome is proposed.
Takayasu's Arteritis: A Case Study
Authors: Fader Rebecca
Published: September 2024

Takayasu's arteritis is a rare type of vascular arteritis that primarily affects women of childbearing age. There are six types involving various combinations of the aorta and its main branches. The vessel inflammation can lead to stenosis, occlusions and/or aneurysms, and a wide range of complications that these can produce. The patient is usually diagnosed based on their symptoms, a physical exam, blood tests, and diagnostic imaging. The case study presented describes a young female patient with multiple manifestations of this disease. At her last imaging with appropriate treatments she was doing very well. Treatments include relieving existing inflammation and any possible complications that it can cause. Takayasu's arteritis can be treated medically or surgically depending on the severity of the case and the prognosis for patients without major complications is very good. Although various imaging modalities are used, ultrasound can detect subtle changes in vessels and can differentiate between arteritis and atherosclerosis.
The Achilles Tendon: An Overview from the Anatomy to the Treatment of Achilles Tendon Ruptures
Authors: Shaikh Nushrat
Published: September 2024

The posterior compartment of the ankle contains the strongest tendon in the body namely the Achilles tendon. Being an extrasynovial tendon, the Achilles is covered in a fatty areolar tissue that allows for a gliding motion thus reducing friction. However, the chronic overuse of the tendon by athletes in recent years has led to an increase in the incidence of Achilles tendon injuries. The aim of this paper is to determine the role and extent of ultrasound as a diagnostic tool in differentiating the two main categories of Achilles tendon injuries: Achilles tendinopathy and Achilles tendon tears. Furthermore, this paper also highlights the recent advancement of ultrasound as a guide in the percutaneous repair of tendon tears.

Ultrasound is a non-invasive method that can help to clearly distinguish between complete and partial thickness tears, evaluate for any changes in tendon thickness and identify the presence of any fluid collections or hematoma.
A Rare Case of Epididymo-Orchitis by Salmonella Infection
Authors: Johal Amrita , He Fiona , Afshar Tannaz
Published: September 2024

Salmonellosis is rare in testes, and is often misdiagnosed as a urinary tract infection (UTI) or sexually transmitted infection. On ultrasound, salmonellosis in testicles often presents as traditional epididymo-orchitis, and can only be differentiated by biochemical diagnosis, often an aspiration. In this case study, a 26-year old immunocompromised male with classic symptoms of testicular infection came for an ultrasound. Upon finding what appeared to be right testicular epididymitis, he was put on oral antibiotics for UTI treatment. The infection did not subside, and he was sent for serial scans. By the time his infection was correctly treated, his right testicle had become atrophic. This case is important for sonographers because ultrasound is the primary imaging modality to investigate scrotal pathology, and so consideration of differential diagnoses for epididymo-orchitis is important. Taking a thorough patient history is an integral part of this process.

Published: September 2024

Introduction:

Vaccine-associated measles is generally not considered to be transmissible, as opposed to wild-type measles, which is one of the most highly contagious diseases. Data on contact and exposure management of vaccine-associated measles is limited, with varied approaches to such cases described in the literature.

Methods:

We report the case of a 2-year-old immunosuppressed child who developed a febrile exanthem with mild conjunctivitis 18 days after receiving the measles-mumps-rubella-varicella vaccine.

Results:

Given the patient's recent measles-containing vaccination while on immunosuppressive medications, consistent clinical findings and the lack of epidemiological risk factors for wild-type infection, the decision was made to treat this as a presumptive case of vaccine-associated measles virus prior to return of confirmatory genotyping results. After consultation with public health experts, contact tracing was not considered necessary. No secondary measles cases were identified, despite a large exposure potential due to lack of consistent airborne precautions during hospital admission.

Discussion:

This case highlights the lack of transmissibility of vaccine-associated measles in immunocompromised hosts, adding to the scant body of literature on this topic, with the potential to inform hospital infection prevention and control as well as public health management in similar situations.

Prophetic Leadership
Authors: Mohd Ezamir Azral Bin Mohd Azrul
Published: September 2024

The hour is dire. Modern man has progressively backed itself into a moral and philosophical corner of which it may not be able to escape from, as timeless civilisational values like justice, honour, compassion, dignity and accountability in the form of true governance and leadership are now being torn down to make way for the rise and dominance of individualist notions of freedom, arrogance and greed, to name a few. In looking at current events saturating the world in this ‘new normal’ endemic of poor leadership, and the global leaders making the headlines with atrocious policies and self-serving governance, my mind paints a picture of the world as a ship, ever making its way towards its journey’s end, while constantly bearing its way through the tumultuous seas, all the while staving off efforts by 10,000 self-helming captains to run it asunder, all with no true knowledge of the subject of sailing to begin with.

Published: September 2024

The article deals with the issue of using data serializers for the implementation of projects related to the processing of large volumes of data, as well as the support of high-speed data transmission in distributed systems. It is shown that in this context, the choice of the most effective serialization mechanism is critical for ensuring the performance and scalability of applications. The purpose of this work is to study the effectiveness of data serializers of the C# programming language by developing a software product for testing serializers using objects of different size and type. A review of scientific research on the use of various data serialization formats: XML, JSON, BSON, MessagePack, Smile, Protocol Buffers, Flat Buffers, Apache Thrift was conducted. It was concluded that XML and JSON formats are the most popular today, and their comparative analysis was performed. The expediency of using the JSON serialization format is substantiated, which is due to its safety compared to the binary format, its smaller size compared to the XML format, as well as the support of most software development tools. The .NET framework is chosen, which provides standard tools for JSON serialization of the C# programming language, namely: System.Runtime.Serialize.Json and System.Text.Json, which are supplied by default. The most popular software solutions for serializing C# objects are analyzed, the feasibility of testing such serializers as Jil, Json.NET, Utf8Json, SpanJson and standard serializers is shown in order to identify the advantages and disadvantages of their use for the implementation of specific tasks and projects. The C# BenchmarkDotNet programming language library was chosen to create the tester program. It is noted that this framework of the .NET platform allows you to convert methods into tests and create performance testing thanks to a powerful statistical mechanism. A class diagram and a component diagram of the developed software are given. A study of 5 data serializers was conducted, which included the execution of 7 experiments on serialization of objects with different types of data. The consumption of time and working memory during serialization of small and large objects was analyzed; objects containing one-dimensional, two-dimensional and three-dimensional arrays of natural numbers, an object with a complex chain of class inheritance, as well as an object containing a dictionary. The results of experimental studies showed the dependence of the effectiveness of serializers on the type and volume of data to be serialized. It is concluded that there is no one-size-fits-all serializer that will perform best in all cases. Recommendations for the use of various serializers are provided, taking into account the requirements of a specific project

Published: September 2024

In current article a process of development of an application for ecological data analysis was researched, particularly pollutants concentration measurements using wavelet transform apparat. To improve the ecological situation and preventing harmful ecological event it is needed to monitor the condition of environment. Ecological monitoring contains a complex system of observations of current environment conditions, observations’ results processing and analysis, creating ecological prognosis including natural and anthropogenic factors. Monitoring data serves as a main source of information for making ecologically significant decisions. Ecological data is stochastic and are extremely random, are known by extraordinary dissipation, directly or indirectly depend on numerous parameters. This data is hard to analyze with methods of classical mathematic, sometimes, when the randomness of the data is high, it could be even impossible. Pollutant’s concentration measurements data makes a time series. In current paper for the analysis of the time series wavelet transform tools were used, either the discrete version or the continuous one, based on those a mathematical model of the process was created. Object-oriented modelling of project’s architecture was created based on provided mathematical model, particularly, classes, components and activity diagrams were built. The application was developed as a cross-platform stand-alone app. After the analysis it was proved to be reasonable to write the application in Python programming language using libraries for mathematical and statistical functions, particularly NumPy, Math, Statistics, and additionally PyWv for wavelet usage assistance. Current application allows to process ongoing and historical data from multiple sources to analyze tendencies of changes in atmosphere condition
The influence of gas heating on the calculated supersonic parameters of gas-powder flow at slag blower in the converter. Message 1
Authors: Kadhim Asseel Mohammed , Tarasiuk L.I. , Kozlovtsev S.V. , Sinelnikov V.O.
Published: September 2024

The article shows that one of the priority tasks in steel production technology is to increase the durability of the lining of oxygen converters. It is shown that the slag blower is a radical way to increase the durability of the lining of oxygen converters. When blowing the melt with oxygen, the MgO content in the slag is 6-8%. To increase the chemical affinity of the slag and the lining, it is proposed to blow the converter slag with jets of nitrogen or powder gas. To achieve optimal chemical affinity of the lining and slag, it is recommended to modify the latter by increasing the content of magnesium oxide in it to 12-14%. Increased durability of the lining makes it possible to solve the problem of replacing wasteful wastes of coal slag and changing environmental concerns on the excess media. It is shown that an attempt to increase the efficiency of modeling very complex processes of interaction of supersonic jets with converter slag has not yet been solved a. A critical analysis of existing methods for constructing mathematical models based on the use of known gas-dynamic laws of interaction of free turbulent jets with the melt is carried out. It has been established that only supersonic jets with their characteristic shock-wave structure always enter the slag melt. An integral method for calculating the parameters of a gas-powder flow in a supersonic nozzle taking into account the powder concentration is presented. It is determined how heating of the gas suspension affects the required pressure in front of the nozzle block, the speed and flow density in the outlet section of the supersonic nozzle. The gas dynamics system is connected to the heat exchange of the flowing gas-dispersed mixture in the Laval expansion nozzles to establish the heating effect in front of the nozzle block of the two-phase gas suspension to a temperature that will ensure
The increase in the fluidity of the gas flow is doubled and its kinetic energy is increased threefold. The method of expanding the parameters of the gas-powder flow between the Laval expansion nozzle involves the infusion of 10 physical effects into 14 parameters of the gas-powder flow. It is shown that numerical expansions allow the tuyere body to be used as a heat exchanger for heating the gas suspension, as well as for increasing the pressure of the gas-powder jet that flows from the nozzles
Modeling of dynamic modes of a generalized pumping station with an asynchronous electric drive of centrifugal pumps
Authors: Lysiak V.H.
Published: September 2024

Transportation of large volumes of liquid to distribution pipelines is provided by transit facilities - main pipelines and pumping stations, which consume significant amounts of electricity and are of strategic importance. The requirements for continuity, reliability, safety, fault finding, and diagnosis of existing, as well as requirements for the design of new strategic objects, are usually regulated by national legislation. The possibility of conducting physical experiments to analyze the modes of operation of such complexes is significantly limited by the inadmissibility of interrupting their functioning, as well as technical and financial risks. The use of a hybrid model consisting of a digital model of the power equipment and a physical model of the control system makes it possible to solve this problem. In this work, attention is focused on the digital model of power equipment. Based on the system approach and the principle of electrohydrodynamic analogy, a formalized mathematical model of the generalized system of asynchronous centrifugal pump units of a multi-unit pumping station with asynchronous electric drive of centrifugal pumps was created. The use of the principle of electrohydraulic analogy made it possible to apply the basic principles of the theory of electric circuits to form the equations of the hydraulic subsystem. The achieved formalization makes it possible to automate the formation of equations to obtain a model of an object of a specific configuration. The use of pump parameters in the model, which depend on the geometry of the internal elements, the speed of the impeller, and the physical properties of the liquid, makes it possible to investigate the impact of emergency and operational deviations of the equipment characteristics on the operating modes both at the level of individual modules and at the level of the pumping station as a whole. The obtained mathematical model was verified by adapting it to the pumping station of the given configuration. A computer simulation of several operational and emergency modes of operation of a pumping station with four hydraulically connected pumps was carried out. The scope of use and ways of improving the developed model are proposed, as well as the direction of further research

Published: September 2024

This paper presents an analysis of the results obtained using the ERS 5000 TechSim Engine Room Simulator software. The software simulates remote control from the ship's central control station using virtual equipment panels, which are dedicated hardware combined into a separate console. The simulator covers the main areas of training in accordance with the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers with the Manila Amendments of 2010 and meets the requirements of IMO Conventions and Resolutions and IEC standards. The simulator is certified by the Norwegian classification society DNV/GL. Main engine diagnostics are performed using the Cylinder Combustion Quality diagnostic panel and the Indicator Diagram Comparison panel. Analysis of changes in gas turbine engine parameters and the indicator diagrams themselves at different levels of piston ring wear showed a decrease in compression pressure, mean indicated pressure and maximum combustion pressure, as well as an increase in the return oil temperature of the piston cooling system and the consumption of lubricating oil in the cylinder. The advantages of using simulators in the training process include the ability to perform laboratory work in a frontal method, which significantly improves the learning experience
Modern approaches to data storage: comparison of relational and cloud data warehouses using etl and elt methods
Authors: Boyko N.I. , Chernenko A.V.
Published: September 2024

The paper analyses various aspects of the use of relational and cloud data warehouses as well as methods of integrating ETL and ELT data. A comparative analysis of these approaches, their advantages and disadvantages are provided. A central relational data warehouse is proposed that provides a single version of truth (SVOT), which allows standardising and structuring data, avoiding differences and providing the access to the same information for all users of an organisation. It is analysed the methodological approaches to implementing a data warehouse: top-down, bottom-up, and from middle. It is described cloud data warehouses that use cloud technologies to provide scalability, availability and fault tolerance, which is important for the companies with huge amounts of data. The advantages and disadvantages of ETL and ELT are analysed: ETL transforms data before it is loaded into the warehouse, which makes it easier to maintain data confidentiality. ELT performs transformation after loading, which allows for more flexible data processing directly in the warehouse. In the article, we deal with the approaches to implementing a data warehouse: top-down is suitable for strategic planning, bottom-up allows for faster results, and the middle approach combines both methods to achieve optimal efficiency. We considered cloud data storage: compared to relational storage, cloud storage is more flexible, scalable and efficient, providing speed and reducing infrastructure costs. It is described cloud storage architectures: massive parallel processing, hybrid architectures, lambda architectures, and multi-structured architectures. They provide high performance and flexibility in data processing. It is described data storage technologies: Data Lake, Polyglot Persistence, Apache Iceberg, Apache Parquet, and columnar databases that provide efficient storage and processing of large amounts of data

Published: September 2024

Information monitoring is the most important stage of monitoring the technical condition of a modern car in operating conditions. Remote control of vehicle operation can be rationally formed on the basis of the systematization of the hardware schemes of the monitoring systems. In the article, a structural analysis and synthesis of possible hardware schemes of vehicle monitoring systems in interaction with the infrastructural environment is performed on the basis of the study of the technical system «Vehicle – Infrastructure». The article systematizes monitoring systems according to the types of hardware used to obtain information about the vehicle and infrastructure environment at various stages of performance of their inherent functions in operational conditions. The article shows that it is advisable to consider the means of obtaining information about the condition of operators, vehicles and objects of transportation (cargo or passengers) as separate functional elements of the monitoring information system. In order to systematize possible schemes of hardware support of monitoring systems, 5 functional elements are selected as a set of specialized hardware. For each of the functional elements of the monitoring information system, the main morphological features that characterize the type of information, methods of obtaining, processing, transmitting, analyzing and using it to solve specific tasks of vehicle operation are highlighted. A list of specific options for technical support of selected morphological features is determined, the combination of which determines the structure and functionality of the formed information monitoring system to solve the tasks in the specified operating conditions. The article shows the process of researching the formation of diagrams of the structure of the hardware of information systems for monitoring the operation of vehicles with different layouts in the form of a morphological formula. The obtained diagram of the structure of the hardware support of information systems for monitoring the operation of the vehicle can be considered as an acting way to ensure effective monitoring of the vehicle in operating conditions
Event risks and scenarios for the 1999 Paddington accident
Authors: Voloshyn V.S.
Published: September 2024

The accident near London in October 1999 didn't just shocks the UK. The collision of the two trains showed the obvious inadequacy of the existing models of train control on the Great Western main line of the UK railways. Specialists from a wide variety of fields of knowledge repeatedly return to this problem, trying to find key ways to minimize risks in this very difficult transportation industry. In this paper, an attempt is made to create a model NS neural network, which makes it possible to predict the possible consequences of a variety of technologically programmed actions, and safe dispatching. The five-sync model is based on all known risk-forming events that contributed to the occurrence of an accident in one way or another. As a function of synapse neuron activation, the bifurcation dependence of the doubled accounting period was chosen due to the number and uncertainty of the content of the accounting indicators that affect the final result. This made it possible to take into account the uncertainties that accompany the occurrence of any intersynapse channels from each input event to the resulting protocol, which assumes only a binary mapping of the expected risk. Thanks to this model, potential and hidden sources of potential risks for any system of events equivalent to the Paddington system are identified, taking into account some of its drawbacks. It is shown that the prevention of such accidents using neural network models should is reduced to automatically tracking images of potential risk-forming events embedded in the trained NS and alerting at least one or two of the monitored ones. It should be noted that such an NS model can be useful not only for the conditions of the Great Western Main Line of the UK railways, but for other systems that are subject to the same operating rules as in our example
O DIVÓRCIO DIRETO E A SUA CONSOLIDAÇÃO COMO DIREITO POTESTATIVO: DA CONTRATUALIZAÇÃO DO CASAMENTO ÀS INOVAÇÕES PRESENTES NO PROJETO DE ATUALIZAÇÃO DO CÓDIGO CIVIL
Authors: Stefanello Matheus
Published: September 2024

O divórcio evoluiu significativamente no Brasil, tornando-se um direito potestativo a partir de mudanças sociais e jurídicas. Este estudo examina essa evolução por meio de revisão bibliográfica e análise de precedentes, explorando a contratualização do casamento e seus impactos no instituto do divórcio. Inicialmente, traça-se um panorama histórico do casamento e do divórcio, destacando sua evolução e de que maneira os elementos de contratualização passaram a ser realidade nesse contexto. Em seguida, aborda-se o divórcio direto como concretização do direito individual e potestativo, enfatizando a relação existente entre sua prática e a liberdade individual; e, ainda, realizando análise jurisprudencial. O estudo investiga, em um segundo momento, o futuro do divórcio direto, considerando o Relatório Final da Comissão de Juristas para a atualização do Código Civil (2024) e as implicações que essas mudanças tendem a causar na sociedade. Também analisa, por fim, o individualismo crescente e a transformação da intimidade após a modernidade, pontos que influenciam a flexibilização das restrições ao divórcio. As conclusões indicam que essa flexibilização é uma tendência crescente, refletindo a expansão do individualismo, a aceleração da velocidade do tempo e a globalização na Era Digital, moldando, assim, um novo paradigma para as relações matrimoniais no Brasil, onde essas outrora já foram indissolúveis.

Noodle snacks are snacks made from fried noodles, which are fried with the addition of seasonings. To improve the nutritional balance of dry noodle snack foods, it is necessary to conduct research by adding beetroot paste as a natural coloring and source of vitamin C. The purpose of this study is to determine the value of consumer preference for noodle snacks with the addition of beetroots and the rate of decline in snack quality. Dried noodles in packaging with the addition of beetroot paste as a source of vitamin C. The study used two types of packaging material, namely PE plastic and aluminum. Average organoleptic test value of noodle snack with addition of beetroot paste to quality attribute: aroma = 4.40; color = 4.32; taste = 4.36; crunchy = 4.28. The rate of quality decline in aluminum packaging against the variable of moisture content and vitamin C followed the rate of zero-order kinetics, with the value of the rate of increase in moisture content = 0.152. Meanwhile, the rate of decrease in vitamin C was -0.102. The results showed that the addition of beetroot paste to the making of noodle snacks was acceptable to the panelists. The addition of beetroot paste also provides a better vitamin C content, which is 3.75 mg/100g. Beetroot snack packaging using aluminum provides a lower rate of reduction in water content and vitamin C content compared to the use of PE plastic packaging materials.
