Frühbyzantinische Kreuzdiskurse des 6. und 7. Jahrhunderts und ihre Rezeption in Konstantinopel, Kappadokien und im Westen
Authors: Warland Rainer
Published: October 2021

The paper establishes connections between funerary art in the Eastern (Cappadocia) and the Western Mediterranean (Lombard kingdom in Northern Italy) during the seventh century. Jewelry pendants and gemstone decorations are also covered. The similarities of the image concepts suggest common design principles, with the cross as a symbol of the Son of Man when God returns on Judgment Day (Mt 24, 30). As celestial signs in the midst of stars and planets, these forms of the cross, which may also have influenced the Baiuvarian and Alemannic gold-leaf crosses, have a cosmic character. Under the sign of the concentric cross, according to Mt 24, 31, the angels gather together the elect (Christians) from the four directions of the world.
A New Edition of the De cerimoniis: No Longer a ‘geteiltes Dossier’?
Authors: Haldon John
Published: October 2021

This review article presents a brief survey of the new critical edition, translation and commentary of the important tenth-century Byzantine imperial treatise known as the De cerimoniis aulae byzantinae (on the ceremonial of the Byzantine court), a title ascribed to the text only in the 16th century. The edition offers an upto- date and highly accurate edition of the tenth century manuscripts through which the text has been transmitted and the detailed and rigorous commentary includes a complete historical and structural analysis of the two books into which the text is divided. In the course of their analysis, the editors arrive at a number of important new conclusions about the origins, intentions and structure of the text, the working methods of the emperor who commissioned it, and the aims and intentions of Basil the parakoimomenos, the person who commissioned the Leipzig manuscript, the chief surviving witness for the text. The 5 volumes of the publication represent a superb achievement by the team of French scholars under the original direction of Gilbert Dagron (†).
Lifting the voices of Spanish-speaking Kansans: a community-engaged approach to health equity
Authors: Showstack Rachel , Duque Silvia , Keene Woods Nikki , López Ana , Chesser Amy
Published: October 2021

An important component of social justice research is centering the voices of those individuals whose lives the research is intended to improve, not as subjects from whom researchers collect data but as active participants in a process of understanding and addressing issues of concern to the community. This ideal of community engagement slows the pace of dissemination of traditional social science or sociolinguistic scholarship but also allows scholars and community members to collaborate to identify and implement meaningful solutions to community problems. We describe a process of engagement of Spanish-speaking patients, interpreters, and healthcare providers in developing a health equity agenda for Spanish speakers in Kansas, grounded in a community-based participatory approach called Patient-Centered Outcomes Research. Stakeholders were engaged through sharing and amplifying their testimonios, stories that tied personal experiences of encountering language barriers in healthcare with calls to action, and they contributed to decisions about what to do with the stories and how to respond to the problems they identified. The result of our engagement process is the formation of a community-based team that has amplified the voices of Spanish-speaking patients and families to reach a range of audiences and responded to a number of evolving community needs. We provide recommendations for language researchers interested in pursuing community-engaged work and explore the possibilities for aligning such work with the expectations of academic institutions.
Dynamical behavior of fractionalized simply supported beam: An application of fractional operators to Bernoulli-Euler theory
Authors: Abro Kashif Ali , Atangana Abdon , Khoso Ali Raza
Published: October 2021

The complex structures usually depend upon unconstrained and constrained simply supported beams because the passive damping is applied to control vibrations or dissipate acoustic energies involved in aerospace and automotive industries. This manuscript aims to present an analytic study of a simply supported beam based on the modern fractional approaches namely Caputo-Fabrizio and Atanagna-Baleanu fractional differential operators. The governing equation of motion is fractionalized for knowing the vivid effects of principal parametric resonances. The powerful techniques of Laplace and Fourier sine transforms are invoked for investigating the exact solutions with fractional and non-fractional approaches. The analytic solutions are presented in terms of elementary as well as special functions and depicted for graphical illustration based on embedded parameters. Finally, effects of the amplitude of vibrations and the natural frequency are discussed based on the sensitivities of dynamic characteristics of simply supported beam.
Reduced graphene oxide coating on basalt fabric using electrophoretic deposition and its role in the mechanical and tribological performance of epoxy/basalt fiber composites
Authors: Mittal Garima , Lee Sang Woo , Rhee Kyong Y.
Published: October 2021

The interfacial bonding between the fiber and matrix plays a pivotal role in deciding the mechanical performance of fiber-reinforced composites. Basalt fibers, due to the absence of surface functional groups, do not interact potentially with the matrix and hence it leads to insufficient load-carrying capacity of the composite. Incorporating nanomaterials in the matrix and surface treatment of the reinforced fiber can improve the fiber–matrix interface. However, poor dispersion of nanomaterials and the complexity of surface treatment methods restrict their industrial applications. Coating nanomaterials directly onto the fiber surface has the potential to distribute the nanomaterials uniformly, along with strengthening the interfacial bonding between the fiber and matrix. In this study, graphene oxide was coated on the basalt fabric through electrophoretic deposition (EPD), and was further reinforced into the epoxy matrix. The aim of this study is to examine the effects of graphene oxide-coated basalt fiber using EPD on the mechanical and tribological performance of the composite. For comparison, epoxy/basalt composites and graphene oxide-coated epoxy/basalt composites were also prepared. Results showed that due to the improved fiber–matrix bonding and uniform distribution of graphene oxide, the coated basalt-reinforced composites showed better tensile strength and less wear loss.
Machine-learning-assisted microstructure–property linkages of carbon nanotube-reinforced aluminum matrix nanocomposites produced by laser powder bed fusion
Authors: Yu Tianyu , Mo Xuandong , Chen Mingjun , Yao Changfeng
Published: October 2021

In this study, the cellular microstructural features in a subgrain size of carbon nanotube (CNT)-reinforced aluminum matrix nanocomposites produced by laser powder bed fusion (LPBF) (a size range between 0.5–1 μm) were quantitatively extracted and calculated from scanning electron microscopy images by applying a cell segmentation method and various image analysis techniques. Over 80 geometric features for each cellular cell were extracted and statistically analyzed using machine learning techniques to explore the structure–property linkages of carbon nanotube reinforced AlSi10Mg nanocomposites. Predictive models for hardness and relative mass density were established using these subgrain cellular microstructural features. Data dimension reduction using principal component analysis was conducted to reduce the feature number to 3. The results showed that even AlSi10Mg nanocomposite specimens produced using different laser parameters exhibited similar Al–Si eutectic microstructures, displaying a large difference in their mechanical properties including hardness and relative mass density due to cellular structure variance. For hardness prediction, the Extra Tress regression models showed a relative error of 2.47% for prediction accuracies. For the relative mass density prediction, the Decision Tress regression models showed a relative error of 1.42% for prediction accuracies. The results demonstrate that the developed models deliver satisfactory performance for hardness and relative mass density prediction of AlSi10Mg nanocomposites. The framework established in this study can be applied to the LPBF process optimization and mechanical properties manipulation of AlSi10Mg-based alloys and other additive manufacturing newly designed alloys or composites.
Migration, Exile, and Homecoming in the Book of Ruth
Authors: Anzi Achia
Published: October 2021

My article examines various artworks from Europe and Israel that portray and are inspired by the Book of Ruth. While in Jewish sources such as the Talmud (Yevamot 47b) Ruth is seen as an immigrant and a convert to Judaism, European artists since the seventeenth century highlighted different episodes and aspects of the biblical story that suited their social, political, and religious worldviews. Notably, the expansion of colonialism during the nineteenth century transformed the depictions of Ruth. While in the canvases of painters such as Pieter Lastman and Jan Victors Ruth is depicted as a model of religious identification, in the paintings of Joseph Anton Koch and Francesco Hayez she epitomises “oriental” otherness. Furthermore, while early European painters underscore the immigration of Ruth, Hayez represents Ruth as a dweller of the “East.” Zionist artists were influenced by European traditions of depicting the Book of Ruth but developed a unique fusion between strategies of identification and differentiation. Artists such as Ze’ev Raban (1890–1970) portrayed the story of Ruth as both ancient and contemporary, while imitating and appropriating Palestinian tropes in order to imagine the Zionist narrative of homecoming. The contemporary Israeli artist Leor Grady (b. 1966), on the other hand, addresses questions of immigration and homecoming while exploring the Book of Ruth in his solo exhibition Bethlehem (2019, Tel Aviv). While Raban’s illustrations ignore the Jewish experience of exile, Grady’s oeuvre epitomises what the Israeli historian Amnon Raz-Krakotzkin sees as “exile within sovereignty.” Instead of recounting a linear historical narrative that begins with exile and culminates with the return to the Promised Land, Grady underscores that every return is also a departure and every departure a return. In this manner, Grady foregrounds the voices silenced by Zionist historiography and challenges the exclusion of the Palestinian narrative.
Hopf bifurcation analysis for liquid-filled Gyrostat chaotic system and design of a novel technique to control slosh in spacecrafts
Authors: Sabir Muhammad , Ahmad Salman , Marwan Muhammad
Published: October 2021

In this article, a fuel tank is coupled with gyrostat in a moving spacecraft to discuss its dynamical behaviour and bringing stability in velocity vectors. Parametric study is performed using Hopf bifurcation to find the bifurcation parameter for a considered mechanical model. Furthermore, a region is constructed in which negligible limit cycles appear around unstable spirals for angular momentum greater than bifurcation point. Based on local dynamical analysis, trajectories of angular velocities are observed with respect to damping constant, which is formulated in the form of bifurcation parameter. Moreover, a controller is designed in this article for considered dynamical system by achieving global stability, with the help of Lyapunov theory, into the spacecraft coupled with filled fuel tank, and their results are compared with effective spacecraft control strategies to observe the effectiveness of our proposed control technique. Finally, in presented research, numerical simulations are performed using MATLAB for validation of analytical results, which the authors have achieved for Hopf bifurcation and designed controller.
Prediction of stock index of two-scale long short-term memory model based on multiscale nonlinear integration
Authors: Tang Decai , Pan Zhiwei , Bethel Brandon J.
Published: October 2021

Although the prediction of stock prices and analyses of their returns and risks have always played integral roles in the stock market, accurate predictions are notoriously difficult to make, and mistakes may be devastatingly costly. This study attempts to resolve this difficulty by proposing and applying a two-stage long short-term memory (LSTM) model based on multi-scale nonlinear integration that considers a diverse array of factors. Initially, variational mode decomposition (VMD) is used to decompose an employed stock index to identify the different characteristics of the stock index sequence. Then, an LSTM model based on the multi-factor nonlinear integration of overnight information is established in a second stage. Finally, the joint VMD-LSTM model is used to predict the stock index. To validate the model, the Shanghai Composite, Nikkei 225, and Hong Kong Hang Seng indices were analyzed. Experiments show that, by comparison, the prediction effect of the mixed model is better than that of a single LSTM. For example, RMSE, MAE and MAPE of the mixed model of the Shanghai Composite Index are 4.22, 4.25 and 0.2 lower than the single model respectively. The RMSE, MAE and MAPE of the mixed model of the Nikkei 225 Index are 47.74, 37.21 and 0.17 lower than the single model respectively, and the RMSE, MAE and MAPE of the mixed model of the Hong Kong Hang Seng Index are 37.88, 25.06 and 0.08 lower than the single model respectively.

Authors: Alkatout Ibrahim , Wedel Thilo , Pape Julian , Possover Marc , Dhanawat Juhi
Published: October 2021

A prerequisite for nerve-sparing pelvic surgery is a thorough understanding of the topographic anatomy of the fine and intricate pelvic nerve networks, and their connections to the central nervous system. Insights into the functions of pelvic nerves will help to interpret disease symptoms correctly and improve treatment. In this article, we review the anatomy and physiology of autonomic pelvic nerves, including their topography and putative functions. The aim is to achieve a better understanding of the mechanisms of pelvic pain and functional disorders, as well as improve their diagnosis and treatment. The information will also serve as a basis for counseling patients with chronic illnesses. A profound understanding of pelvic neuroanatomy will permit complex surgery in the pelvis without relevant nerve injury.

Machine learning and deep learning-based approaches on various biomarkers for Alzheimer’s disease early detection: A review
Authors:   Computer and Information Technology Faculty, Sana’a University, Yemen, M. Fadhl Alqubati Ghada , H. Algaphari Ghaleb ,   Computer and Information Technology Faculty, Sana’a University, Yemen
Published: October 2021

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder. It can cause a massive impact on a patient's memory and mobility. As this disease is irreversible, early diagnosis is crucial for delaying the symptoms and adjusting the patient's lifestyle. Many machine learning (ML) and deep learning (DL) based approaches have been proposed to accurately predict AD before the onset of its symptoms. However, finding the most effective approach for AD early prediction is still challenging. This review explored 24 papers published from 2018 until 2021. These papers have proposed different approaches using state of the art machine learning and deep learning algorithms on different biomarkers to early detect AD. The review explored them from different perspectives to derive potential research gaps and draw conclusions and recommendations. It classified these recent approaches in terms of the learning technique used and AD biomarkers. It summarized and compared their findings, and defined their strengths and limitations. It also provided a summary of the common AD biomarkers. From this review, it was found that some approaches strove to increase the prediction accuracy regardless of their complexity such as using heterogeneous datasets, while others sought to find the most practical and affordable ways to predict the disease and yet achieve good accuracy such as using audio data. It was also noticed that DL based-approaches with image biomarkers remarkably surpassed ML based-approaches. However, they achieved poorly with genetic variants data. Despite the great importance of genetic variants biomarkers, their large variance and complexity could lead to a complex approach or poor accuracy. These data are crucial to discover the underlying structure of AD and detect it at early stages. However, an effective pre-processing approach is still needed to refine these data and employ them efficiently using the powerful DL algorithms.
The role of mitophagy during oocyte aging in human, mouse, and Drosophila: implications for oocyte quality and mitochondrial disease
Authors: Cox Rachel T , Poulton Joanna , Williams Suzannah A
Published: October 2021

There is a worldwide trend for women to have their first pregnancy later in life. However, as oocyte quality declines with maternal aging, this trend leads to an increase in subfertility. The cellular mechanisms underlying this decline in oocyte competence are poorly understood. Oocyte mitochondria are the subcellular organelles that supply the energy that drives early embryogenesis, and thus their quality is critical for successful conception. Mitochondria contain their own DNA (mtDNA) and mutations in mtDNA cause mitochondrial diseases with severe symptoms, such as neurodegeneration and heart disease. Since mitochondrial function declines in tissues as humans age accompanied by an accumulation of mtDNA mutations, mtDNA is implicated as a cause of declining oocyte quality in older mothers. While this mutation load could be caused by declining accuracy of the mitochondrial replisome, age-related decline in mitochondrial quality control likely contributes, however knowledge is lacking. Mitophagy, a cellular process which specifically targets and recycles damaged mitochondria may be involved, but studies are scarce. And although assisted reproductive technologies can help older mothers, how these techniques affect the mechanisms that regulate mitochondrial and oocyte quality have not been studied. With the long-term goal of understanding the molecular mechanisms that control mitochondrial quality in the oocyte, model systems including Drosophila and mouse as well as human oocytes have been used. In this review, we explore the contribution of mitophagy to oocyte quality and the need for further systematic investigation in oocytes during maternal aging using different systems.

Lay summary

Mitochondria are small parts of cells called organelles that generate the chemical energy needed for life. Hundreds of thousands of mitochondria in the developing eggs of the mother support the initial growth and development of the fertilized egg. However, due to increasingly diminished function over time, mitochondria generate less energy as we age, posing real problems for older women considering pregnancy. It is possible that this declining energy could be responsible for declining fertility as women age. Energy may decline because mitochondria fail and the cell’s way of keeping them healthy become less efficient as we age. This review summarizes what is known about mitochondrial quality control in developing eggs as they age. In the future, understanding how the best mitochondria are selected and maintained in the egg, and hence the future baby, may enable older women with or without mitochondrial problems, to have healthy children.
Las emociones en la movilización social: la agenda investigativa en América latina en la década del 2010
Authors: Massal Julie
Published: October 2021

El artículo propone un balance preliminar de las orientaciones analíticas acerca de las emociones en la movilización social y en la política, en Colombia y América latina. Se examina la pertinencia del enfoque emocional en un contexto de renovación de la sociología de la movilización y de diversificación de la investigación empírica latinoamericana. El énfasis en el componente expresivo de la protesta se manifiesta al observar el rol de las emociones frente a la represión o la defensa de las dimensiones subjetivas de la acción colectiva por los actores sociales, más allá de sus objetivos políticos. Con ese recorrido, en recientes estudios de caso, se evalúa qué impactos tienen las emociones en la acción y cómo se vinculan aspectos emocionales y estratégicos. Así, el estudio de la protesta se renueva también al nivel teórico y metodológico, al ampliar la comprensión de lo que “mueve” un actor social y sus participantes.
Formation of a New Economic Model in the Post-Stalinist Soviet Union
Authors: Shcherbakova Tatyana I.
Published: October 2021

Introduction. The article is devoted to the change of economic model in the post-Stalinist USSR. It considers measures through which this model was implemented, its consequences, features and social results are distinguished. Materials and Methods. The results of research are based on statistic of the USSR State Bank and analytical reports of experts published in the issues of edition “On the pages of archival funds of the Central Bank of the Russian Federation”. The author examines the dynamic and problems of money circulation, the social and economic contradictions generated by them. Results. The transition to the inflationary model began with a political course to reject from limiting population monetary income. In 1953–1970, in various forms, the monetary incomes of citizens, including the rural population, low-income, socially unprotected, were significantly increased. These measures led to negative processes in money circulation, to which experts of the State Bank drew the attention of the country’s leadership for a long period. Among them there were: the monetary growth, outpacing the growth in the production of consumer goods and the possibilities of goods turnover; the growth of public deposits in savings bank reflecting unmet demand for consumer goods; the use of public deposits to maintain the solvency of the country’s budget; increasing of the emission. Discussions. The inflationary economic model, implemented in a centralized planning system, had visible features. First, inflation in this model was not accompanied with price increases; secondly, the emission of money was the base for raising the standard of living of the population; thirdly, in this model the social stratification between ordinary citizens and the elite was intensified; fourthly, with transit to the inflationary model the shadow economy got the development. Conclusion. The transition in the USSR to an inflationary economic model improved standards of living in the USSR but predetermined the inevitable economic crisis in the foreseeable future with a high probability of the destruction of socialism.

Összefoglaló. A fizikai inaktivitás a cardiovascularis betegségek –
így a stroke – jelentős kockázati tényezője. A rendszeres testmozgás növeli az
aerob kapacitást, a cardiorespiratoricus fittséget – ezzel csökkenti a
cardiovascularis betegségek, köztük a stroke kockázatát. Az elmúlt évek azon
vizsgálataiból idéz a közlemény, amelyek a fizikai aktivitás, a
cardiorespiratoricus teljesítőképesség szerepét ismertetik a stroke elsődleges
és másodlagos prevenciójában. Említésre kerülnek az aerob kapacitás mérésének
módszerei. A nemzetközi tapasztalatok azt igazolják, hogy magas
cardiorespiratoricus fittség esetén közel harmadával csökken a stroke
előfordulása. A WHO ajánlása mindenkinek a heti legalább 150 percnyi
mérsékelten-közepesen meglihegtető testi tevékenység – ez a leggyakoribb

Summary. Physical inactivity is a significant risk for
cardiovascular diseases, even for stroke. Regular physical activity improves
aerobic capacity, cardiorespiratory fitness, aerob endurance performance
(synonyms), diminishing the risk of cardiovascular diseases as well as the risk
of stroke. We refer to previous literature data from the past two decades
demonstrating the beneficial role of the higher aerob fitness in the primary and
secondary prevention of stroke. Relevant methods of measuring aerob performance
have been described previously. In the case of optimal aerobic fitness, the
occurrence of stroke is lower by a third according to international experience.

Renal Cell Carcinoma with Direct Extension into the Gonadal Vein, Uterus, Fallopian Tube, and Bilateral Ovaries: A Case Report
Authors: Sweigert Sarah E. , Bajic Petar , Aragao Alessa , Picken Maria , Woods Michael E.
Published: October 2021

Renal cell carcinoma (RCC) with invasion into the renal vein is well described; however, invasion into the gonadal vein is a rare event with less than five cases reported in the literature. RCC occasionally presents with metastasis to the ovaries or the fallopian tubes, although this is also a rare occurrence. We present a case of locally advanced left RCC with direct extension into the ipsilateral gonadal vein with extension into the bilateral ovaries and uterus, which has not been previously described. Computed tomography (CT) in a 72-year-old female with a 35-pound weight loss indicated the presence of a 16-cm left renal mass with caudal tumor extension through the left gonadal vein and regional lymph-adenopathy. There was no evidence of distant metastasis, and she underwent an open left radical nephrectomy. Intraoperatively, she was found to have direct extension of the tumor through the left gonadal vein into the uterus, bilateral ovaries, and the left fallopian tube. All visible dis-ease was resected, and retroperitoneal and pelvic lymphadenectomy were performed. The patient had an uneventful hospital course. Pathology revealed clear cell RCC, Fuhrman grade 3. The final pathologic stage was pT4N1M1. The patient was ultimately noted to have pulmonary metastasis and was treated with immunotherapy with no evidence of disease progression.

Authors: M. Nahouraii Lauren , L. Allen Jordan , B. Merrill Suzanne , Lehman Erik , G. Kaag Matthew , Raman Jay D.
Published: October 2021

Pathologic characteristics of extirpated renal cell carcinoma (RCC) specimens <7 cm were reviewed to get better information on technical nuances of renal mass biopsy (RMB). Specimens were stratified according to tumor stage, nuclear grade, size, histology, presence of lymphovascular invasion (LVI), necrosis, and sarcomatoid features. When considering pT1 (0–7 cm) tumors, pT1b (4–7 cm) RCC masses were more likely to have necrosis (43% vs 16%, P < 0.001), LVI (6% vs 2%, P = 0.024), high-grade nuclear elements (29% vs 17%, P < 0.001), and sarcomatoid features (2% vs 0%, P = 0.006) compared with pT1a (0–4 cm) tumors. Additionally, pT3a tumors were more highly associated with necrosis (P = 0.005), LVI, sarcomatoid features, and high-grade disease (P for all < 0.001) when compared to pT1 masses. For masses ≤ 4 cm, pT3a cancers were more likely to demonstrate necrosis (38% vs 16%, P < 0.001), LVI (22% vs 2%, P < 0.001), high-grade nuclear elements (45% vs 17%, P < 0.001), and sarcomatoid features (12% vs 0%, P < 0.001) compared to pT1a tumors. Similarly, for masses 4–7 cm, pathologic T3a tumors were significantly more likely to have sarcomatoid features (12% vs 2%, P = 0.006) and LVI (22% vs 6%, P = 0.003) compared to pT1b tumors. In summary, pT3a tumors and those RCC masses >4 cm exhibit considerable histologic heterogeneity and may harbor elements that are not easily appreciated with limited renal sampling. Therefore, if RMB is considered for renal masses greater than 4 cm or those that abut sinus fat, a multi-quadrant biopsy approach is necessary to ensure adequate sampling and characterization of the mass.

Published: October 2021

An important component of the development of degenerative changes in the spine is damage and disruption of the vital acti­vity of the paravertebral muscles. Objective. Based on the analysis of biochemical parameters of laboratory rats serum we evaluated the suitability of the studied models of dystrophic muscle tissue lesions for further study of the development of degenerative-dystrophic disorders in the spinal motor segments. Methods. Simulated: group I (5 female rats) — alimentary obesity by keeping for 3 months. on a high-calorie diet (hyperlipidemic diet); group II (5) — ischemia by ligation for 45 days of large back rectus muscles the with suture material that is not absorbed. Control — 5 intact animals of the same age and sex, which were kept on a standard diet. Serum levels of glycoproteins, haptoglobin, total chondroitin sulfates (CHS), glucose, cholesterol, low-density lipoproteins, triglycerides, total lipids, activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline and acid phosphatases, creatine phosphokinase were defined, thymol test was determined. Parameters were processed by the Fisher–Student method. Results. In the I group of rats, the content of glycoproteins, total cholesterol and lipids, low-density lipoproteins, triglycerides, glucose, CHS, ALT and AST activity, thymol test va­lues were increased and the level of creatine phosphokinase activi­ty was decreased. In animals of group II, an increase in serum activity of creatine phosphokinase, glycoproteins and CHS was recorded. Conclusions. Changes in the serum biochemical parameters of white rats recorded on a hyperlipidemic diet indicate the development of fatty degeneration, including in muscle tissue.

It is impossible to find out the number of patients with knee joint instability (KJI) in case of congenital malformations of the lower extremities (CMLE). Children, adolescents and young people usually adapt well to this abnormality, so they rarely present with symptoms of instability, even with positive tests. The main reasons for the manifestation of KJI in CMLE are inadequate loading, injuries of the lower extremity and surgical correction. Objective. Based on the assessment of the scientific literature to define the KJI terminology, to identify the main causes of its development and clinical manifestations in conditions of CMLE, to identify trends in the treatment tactics. Methods. More than 500 articles from international libraries PubMed, NCBI, Google Scholar, Medscape, MedlinePlus were searched and analyzed. Taken into account the rarity of the abnormality and the small amount of research in recent years, the depth of the search was 25 years. Results. KJI in children with CMLE may be a consequence of congenital structural features of the lower extremity (isolated malformation in the form of agenesis of the cruciate ligaments or inferiority of the ligament of the knee joint in complex abnormality) and complication of surgical correction of longitudinal defects of the extremities. As the abnormality is not well studied, the tactics for such patients still remain the topic of discussion. The expediency of surgical stabilization of the knee joint has not been conclusively proven due to the fact that in the case of its anomalies certain adaptive mechanisms are formed, which on the one hand are not appropriate to violate, and on the other hand, the current level of medicine allows to promote patients’ functional capabilities, inducing KJI progressing. Conclusions. Children with CMLE adapt well to the concomitant KJI, so in everyday life and prior to surgical correction of CMLE, it does not bother patients. Particular attention should be paid to the stability of the knee joint both before and during prolongation and correction of deformity. The variability and severity of CMLE determines the implementation of multi-stage surgical treatment and surgical stabilization of the knee joint to improve extremity function may be one of them. Key words. Children, knee joint instability, congenital malformations, lower extremities, surgical treatment.

ABSTRACT Acute appendicitis is the leading cause of abdominal emergency surgery worldwide and appendectomy continues to be the definitive treatment of choice. This cost-effectiveness analysis evaluates laparoscopic versus open appendectomies performed in public health services in the state of Bahia (Brazil). We conducted a retrospective observational study using the database from the Department of Informatics of the Unified Health System (DATASUS). Available data on appendectomies between 2008 and 2019 were included, and we evaluated the temporal trend of hospital admissions, procedure-related mortality rates, length of stay, and costs. Statistical analysis was performed using the R-software (R Foundation, v.4.0.3) and the BioEstat software (IMDS, v. 5.3), considering p<0.05 as significant. During 2008-2019, 53,024 appendectomies were performed in the public health services in Bahia, of which 94.9% were open surgeries. The open technique was associated with a higher mortality rate (4.9/1,000 procedures; p<0.05) and a higher risk of death (RR=4.5; p<0.05) compared to laparoscopy (1.1/1,000 procedures). Laparoscopic appendectomy (median of 2.7 days) had a shorter length of stay compared to laparotomy (median of 4.15 days) (p<0.05). There was no difference in the medians of costs nor hospital services, per procedure (p=0.08 and p=0.08, respectively). Laparoscopic professional median costs were higher by US$ 1.39 (p<0.05). Minimally invasive surgery for appendicitis is a safe and efficacious procedure in Brazilian public health care services, as it provides advantages over the open method (including lower procedure-related mortality rate and earlier discharges), and it did not imply higher expenses for public service budgets in the state of Bahia.

Resumo Este estudo tem por objetivo verificar o sofrimento associado às dores crônicas, por meio do instrumento projetivo “Retrato da Dor”. Trata-se de um estudo descritivo, realizado com 126 pacientes com dores crônicas de diversas etiologias. As respostas foram analisadas de acordo com o método de análise de conteúdo de Bardin e testes estatísticos. Foram encontrados pacientes: que acreditam que nenhum sofrimento se compara com a sua dor (34,9%); que comparam sua dor a outras dores ou doenças já experienciadas (16,6%); e os que comparam a dor a situações de sofrimento emocional (48,4%). Este estudo evidenciou que os aspectos emocionais desempenham um papel importante na maneira como o indivíduo irá interpretar e utilizar recursos próprios para lidar com suas dores.
Meanings of work for manicurists and hairdressers: employees and pejotizados
Authors: Souza Mariana Machado , Borges Livia de Oliveira
Published: October 2021

Abstract The research aimed to identify the differentiation of meanings of work among beauty salon workers, considering the work contracts and the functions performed (hairdressers and manicurists), in a context of pejotização and functions’ internal hierarchy. We applied questionnaires to 171 manicurists and hairdressers with the following types of links: employee, informal, MEI pejotizado and MEI não pejotizado. The results indicated that employees perceive with greater intensity the work as a responsibility and as a way of being socially included, and more proportionality in social and financial retribution. They also indicated that manicurists experience with more intensity the characteristics of brutalization, discrimination and demand.

Published: October 2021

ABSTRACT: This research was performed to ascertain the most suitable Artificial Neural Network (ANN) model to quantify the degree of fraud in powdered milk through the addition of powdered whey via regular standard physicochemical analyses. In this study, an evaluation was done on 103 samples with different quantities of added whey powder to whole milk powder. Using Fourier Transform Infrared Spectroscopy the fat, cryoscopy, total solids, defatted dry extract, lactose, protein and casein were analyzed. The hyperbolic tangent transformation function was used with 45 topologies, and the Holdback and K-fold validation methods were tested. In the Holdback method, 75% of the database was employed for training, while 25% was used for validation. In the K-fold method, the database was categorized into five equal sized subsets, which alternated between training and validation. Of the two methods, the K-fold method was proven to have superior efficiency. Next, analysis was done on three models of multilayer perceptron networks with feedforward architecture. In Model 1, the input layer contained all the physicochemical analyses conducted, in model 2 the casein analysis was excluded, and in model 3 the routine analyses performed for dairy products was done (fat, defatted dry extract, cryoscopy and total solids). From Model 3 an ANN was derived which could satisfactorily predict fraud calculated from using the routine and standard analyses for dairy products, containing 64 nodes in the hidden layer, with R2 of 0.9935 and RMSE of 0.5779 for training, and R2 of 0.9964 and RMSE of 0.4358 for validation.

Abstract The life cycle of stink bug, Glyphepomis dubia and the development of two egg parasitoids (Telenomus podisi and Trissolcus basalis) were studied at the Federal University of Maranhão, at 26 ± 2oC, relative humidity (RH) of 60 ± 10% and 12h photophase. Individuals used in the study were collected from seven rice fields located around the municipality of Arari, Maranhão, Brazil, and maintained in greenhouse and laboratory for the life cycle studies. From egg to adult, G. dubia took 35.2 days to complete the life cycle. The oviposition period was 37 days, with egg masses of about 12 eggs each and viability of 93.1%. Longevity was 53 and 65 days for females and males, respectively. The egg parasitoids Te. podisi and Tr. basalis parasitized and developed in G. dubia eggs; however, the biological characteristics of Tr. basalis were affected. Emergence of the parasitoids was higher for Te. podisi (83.5%) compared to the records for Tr. basalis (50.4%). Therefore, G. dubia may potentially achieve a pest status and Te. podisi is a promising biological control agent for G. dubia management in Brazil due to its higher longevity and better reproductive parameters.
