Published: February 2023

This study aims to explore the mechanism of microRNA (miR)-101-3p-mediated SOX2/ZIC5 axis in the progression of cisplatin resistance of nasopharyngeal carcinoma (NPC). ZIC5 expression was analyzed with a bioinformatics database and detected in NPC cell lines. Cisplatin-resistant cells (HNE-1/DDP and C666-1/DDP) were transfected with sh-ZIC5, sh-SOX2, sh-SOX2 + pcDNA3.1-ZIC5, or miR-101-3p Agomir + pcDNA3.1-SOX2. MiR-101-3p, SOX2, and ZIC5 expression was assessed after transfection, and cancer associated phenotypes were evaluated after cisplatin treatment. The potential relationships among miR-101-3p, SOX2, and ZIC5 were analyzed. A xenograft mouse model of NPC was established with HNE-1 cells stably transfected or not transfected with oe-ZIC5 and subjected to tail vein injection of miR-101-3p Agomir and intraperitoneal injection of cisplatin. Overexpression of ZIC5 was found in cisplatin-resistant NPC cells. Downregulating ZIC5 in NPC cells decreased cell viability, promoted apoptosis, and reduced cisplatin resistance. SOX2 had a binding site on ZIC5, and SOX2 promoted proliferation, migration, and cisplatin resistance and inhibited cell apoptosis by up-regulating ZIC5. Mechanistically, miR-101-3p was decreased in cisplatin-resistant NPC cells and negatively targeted SOX2. Overexpression of miR-101-3p inhibited tumor growth and cisplatin resistance in xenograft mouse model, which was reversed by ZIC5 overexpression. In conclusion, the miR-101-3p/SOX2/ZIC5 axis was implicated in cancer associated phenotypes and cisplatin resistance in NPC.

This study investigated the molecular mechanisms underlying the involvement of the Notch signaling pathway and autophagy in the development of pulmonary fibrosis in pigeon breeder’s lung (PBL). Rats were divided into control (Ctrl), PBL model (M), M + D (Notch signaling inhibition), M + W (autophagy inhibition), and M + R (autophagy induction) groups. Lyophilized protein powder from pigeon shedding materials was used as an allergen to construct a fibrotic PBL rat model. The mechanism by which Notch signaling regulated autophagy in the pulmonary fibrosis of PBL was investigated by inhibiting the Notch pathway and interfering with autophagy. Pulmonary interstitial fibrosis was significantly greater in the M group and the M + W group than in the M + D and M + R groups. The expression of α-smooth muscle actin was significantly higher in the M, M + D, and M + W groups than in the Ctrl group (P < 0.05). The expression of the cell autophagy markers Beclin1 and LC3 was lower in the M, M + D, and M + W groups than in the Ctrl group (P < 0.05), whereas Beclin1 and LC3 expressions were higher in the M + D and M + R groups than in the M group. The levels of reactive oxygen species in serum and lung tissues were higher in the M, M + D, M + W, and M + R groups than in the Ctrl group (P < 0.05). The Notch signaling pathway is involved in the pathological process of pulmonary fibrosis in the rat model of PBL by regulating autophagy.
De Dilma a Bolsonaro: as transformações matriciais na política externa brasileira
Authors: Reis da Silva André Luiz
Published: February 2023

Este artigo analisa as transformações recentes na política externa brasileira, a partir da crise política que resultou na destituição da Presidente Dilma Rousseff. Para tanto, analisa o contexto internacional e interno e realiza uma avaliação da política externa dos governos Dilma Rousseff (2011–2016), Michel Temer (2016–2018) e Jair Bolsonaro (a partir de 2019), para os eixos regional, multilateral e bilateral. Utilizando pressupostos de Análise de Política Externa (APE), esta pesquisa analisa simultaneamente os condicionamentos internos e internacionais para a formulação da política externa, identificando atores e interesses. Tem como hipótese de que a política externa brasileira já vinha sofrendo uma crise e reorientação matricial durante o Governo Dilma, baseada na crise política e econômica interna e na transformação das bases internacionais do Brasil, com a fragilização da integração regional e paralisia das negociações multilaterais. As diretrizes da política externa promovida pelo Governo Temer refletiram a conjuntura internacional, a crise brasileira e os interesses de um novo bloco de poder, que procura reorientar a política externa brasileira para uma nova matriz de projeção internacional, mas permaneceu como um período de transição. Já com o Governo Bolsonaro verifica-se uma inflexão matricial na política externa brasileira, com fortes significados internos e internacionais, tendo como principal condicionante a ascensão da direita conservadora.
El Galeón de Manila y el comercio de Asia: Encuentro de culturas y sistemas
Authors: Villamar Cuauhtemoc
Published: February 2023

Para tener una perspectiva más clara sobre la importancia de los intercambios económicos y culturales que se realizaron a través del Océano Pacífico a partir del último cuarto del siglo XVI, es fundamental resaltar las interacciones entre culturas y sistemas de intercambio tanto asiáticos como occidentales. En la literatura sobre el Galeón de Manila se tiene al año 1571, fecha en que se fundó Manila como capital de Filipinas, como el punto de inicio de un mecanismo de comercio que mantuvo en constante contacto a ambas orillas del Océano más grande del planeta por dos siglos y medio. En este breve ensayo no es posible hacer una historia detallada de todos los encuentros que se produjeron entre Asia y América española a lo largo de los siglos. En cambio, el lector podrá obtener información sobre algo más sutil, que es el establecimiento de una relación cultural profunda a partir de los intercambios económicos entre Asia, compleja y variada, y las sociedades en el continente americano bajo dominio de la Monarquía española. Me refiero a la etapa inicial de ese encuentro, que dejó una profunda huella cultural, sobre todo por la influencia asiática en la América bajo el dominio español, que comienza a ser revalorada.

Published: February 2023

Las cuencas hidrográficas integran una serie de procesos y características medioambientales que se expresan en la morfometría de las redes de drenaje. El análisis morfométrico resulta clave para la comprensión del funcionamiento del sistema hidrológico de una cuenca. Su uso resulta práctico en zonas con limitada información climatológica y falta de conocimiento sobre el funcionamiento del sistema hidrológico. Este trabajo tiene como objetivo principal caracterizar la geomorfología de las subcuencas Grijalva y Usumacinta en el sureste de México usando sistemas de información geográfica (SIG) y una serie de parámetros morfométricos asociados a características generales, al relieve, a la red de drenaje y a la forma de estas subcuencas a fin de analizar y comprender el comportamiento hidromorfológico. Los resultados obtenidos muestran cierto contraste entre ambas cuencas en torno al parámetro de número de escurrimientos, lo cual tiene implicaciones en lo relativo a la energía y a la capacidad y magnitud de la captación de agua de la subcuenca y de la red fluvial de ambas subcuencas. En este contexto, se busca contribuir al conocimiento local y al fortalecimiento de la toma de decisión en los ámbitos de ordenamiento territorial, protección civil, infraestructura y políticas públicas.
The Perceptual and Emotional Consequences of Articulation in Music
Authors: Carr Nathan R. , Olsen Kirk N. , Thompson William Forde
Published: February 2023

Two experiments investigated perceptual and emotional consequences of note articulation in music by examining the degree to which participants perceived notes to be separated from each other in a musical phrase. Seven-note piano melodies were synthesized with staccato notes (short decay) or legato notes (gradual/sustained decay). Experiment 1 (n = 64) addressed the impact of articulation on perceived melodic cohesion and perceived emotion expressed through melodies. Participants rated melodic cohesion and perceived emotions conveyed by 32 legato and 32 staccato melodies. Legato melodies were rated more cohesive than staccato melodies and perceived as emotionally calmer and sadder than staccato melodies. Staccato melodies were perceived as having greater tension and energy. Experiment 2 (n = 60) addressed whether articulation is associated with humor and fear in music, and whether the impact of articulation depends on major vs. minor mode. For both modes, legato melodies were scarier than staccato melodies, whereas staccato melodies were more amusing and surprising. The effect of articulation on perceived happiness and sadness was dependent on mode: staccato enhanced perceived happiness for minor melodies; legato enhanced perceived sadness for minor melodies. Findings are discussed in relation to theories of music processing, with implications for music composition, performance, and pedagogy.

Nowadays, the use of recyclable, eco-friendly materials in automotive industries are growing due to the environmental concerns in place of synthetic polymers. Natural filler materials are increasingly used to reduce the usage of the polymer matrix and to improve the mechanical, thermal properties of the composite materials. Natural fiber and filler incorporated hybrid composite materials are used in places where the load requirements are low. This study focuses on the use of Almond shell as a particulate reinforcement in the Aquilaria agallocha Roxb reinforced Epoxy composite with different volume fractions. The specimens were fabricated using hand layup process and the mechanical properties were investigated. The results had shown that the composite with 20% v/v Almond shell particulate reinforced composite had shown better mechanical properties. While the Visco elastic properties had shown minor improvement due to the incorporation of natural filler in the hybrid composite material.

Published: February 2023

Histopathological differentiation in pediatric adrenocortical carcinoma (pACC) is difficult and clinical prediction and stratification scores are not evaluated yet. Therefore, this review aims to summarize current evidence on the value and accuracy of the two commonly used scoring systems (Weiss/Armed Forces Institute of Pathology (AFIP)) pACC. On this base, one might be able to evaluate if patients may benefit from a unique scoring system. For this, we performed a systematic review of the published literature and included 128 patients in our analysis. The majority (72%) of the pACCs had a good clinical course. The follow-up time ranged from 0 to 420 months with a mean age of 5.6 years at diagnosis. Patients with a good clinical course were younger (mean 4.8 years) than patients with a poor outcome (mean 7.6 years). Comparing the two scoring systems, the specificity of the Weiss score was very low (25%), whereas the sensitivity was 100%. According to the AFIP score, specificity (77%) was higher than the Weiss score, whereas the sensitivity of the AFIP score was minimal lower with 92%. Age differences were recognizable as the specificity was lower in infants <4 years (20%) than in older children (32%). In contrast, the specificity of the AFIP score was higher in infants <4 years (82%) than in older age groups (76%). Summarizing our results, we could show that the Weiss score is not a suitable tool for the prediction of malignancy in pACC in comparison with the AFIP score, but further efforts may seek to ensure early and accurate stratification through augmented scoring.
Burst Ratio of Packet Losses in Individual Network Flows
Authors: Chydzinski Andrzej , Adamczyk Blazej
Published: February 2023

We study the burst ratio of packet loss processes in networking. This parameter characterizes the inclination of packet losses to form long, consecutive sequences. Such long sequences of losses may have a negative impact on multimedia streams, particularly those of real-time type. In packet networks, the burst ratio is often elevated due to overflows of packet buffers, which are present in all routers and switches. In the article, we investigate the burst ratio in the per-flow manner, i.e. individually for every flow of packets traversing a network node. We first confront all the per-flow burst ratios with each other, as well as with the burst ratio computed for the multiplexed traffic. Next, we study the influence of different features of the system on these burst ratios. In particular, the influence of rates of flows and their proportions, the standard deviation of interarrival times, the capacity of the buffer, the system load and the distribution of the service time, is studied. Special attention is paid to models with non-Poisson flows, which are not analytically tractable.
Bertin JM, Cummings RM, aerodynamics for engineers, 6th ed., 2022, Book review
Authors: Grammenos Theophanes
Published: February 2023

This well-written, new and revised edition of Aerodynamics for Engineers comes both as a legacy of (the late) Professor John Bertin and a “gem” addressing mainly aeronautics and aerospace engineering students but also physics and applied mathematics students with an interest in compressible fluid flow and its various applications. Professor Russell Cummings has done a superb job to maintain the book’s fame in the topic of aerodynamics. Several sections have been rewritten taking into account the more recent developments in the subject. For instance, many new examples have been added in order to enhance the reader’s understanding and his capability of applying the theoretical concepts to “real life” situations (concerning mostly military aircraft applications), new sections are added to cover a series of topics that are significant to aerodynamics, such as applications of potential flow, converging/diverging nozzles, and characteristics of hypersonic flow, just to name but a few. Furthermore, references as well as figures and photographs have been updated, and answers to selected problems are included.

Published: February 2023

The paper presents the variables of an airfoil that has a direct impact on the movement of the airplane. The test evaluation of the impact of chaotic disturbances caused due to atmospheric or any other external conditions on the entire plane is a difficult process mainly due to the size of the airplane, so instead of testing on the entire airplane, it is divided into different parts and each part is individually calculated and the test of all the parts are put together and averaged to get the average turbulence impact on the entire plane. This paper has the results of all the different variables that directly or indirectly impact the airplane, that can cause a chaotic movement impacting the airplane movement, and its velocity based on the density and thickness.

Childhood obesity and curcumin: a possible effective anti-obesity adjunct
Authors: Marks Ray
Published: February 2023

Obesity, a largely intractable health condition with incalculable health, financial and social costs and ramifications and often emerging in the context of early childhood and without amelioration thereafter, remains an immense challenge to mitigate effectively, despite years of study. Consequently, interventions that can limit the early onset of obesity, or help to reduce this to any degree where present, remain of high significance. Studied now for over 20 years, the role of spices such as turmeric that contains a yellow pigment known as curcumin, a derivative employed widely in Asian dietary and health contexts for centuries appears promising for purposes of combating obesity and its analogues such as diabetes. Based on available data, this mini review specifically discusses some findings regarding curcumin and obesity, and what has been observed to date. Extracted from current literature, it is concluded that this is a field of significant promise, but one requiring more research among young people as well as diverse obesity associated conditions across time.
Coexistence of Takotsubo cardiomyopathy and acute myocardial infarction
Authors: Mohapatra MD Ashish K
Published: February 2023

Takotsubo cardiomyopathy is one reversible heart disease, which presents as an acute myocardial infarction with ST-elevation in ECG. This Takotsubo Cardiomyopathy is one of the Cath laboratory diagnosis, that means, if the apical ballooning along with absence of obstruction of the corresponding coronary artery, then only the Takotsubo cardiomyopathy is diagnosed. But however there may be some exceptions. We describe a case of 80yr old male presenting the Emergency department with typical anginal symptoms for 3hours suggestive of acute myocardial infarction. The initial ECG demonstarted lateralwall Infarction. Serology revealed elevated cardiac Enzymes. As per the guidelines one emergency coronaryangiography was performed and revealed occluded Ramus diagonalis-2 and Plaque Rupture in mid segment of Right coronary artery, the ventriculography confirmed apical ballooning consistent with takotsubo cardiomyopathy and not in the vascular territory supplied by the occluded epicardial vessel. Traditionally, the Takotsubo Cardiomyopathy is labelled as a diagnosis only in absence of the obstruction of the corresponding coronary artery. This case however reflects the coexistence of the obstructed coronary artery and the takotsubo cardiomyopathy and moreover in a male, so the diagnostic criteria for Takotsubo cardiomyopathy my need a prompt review and this case definitely adds to the number of coexistence.

Published: February 2023

Patients who present a background of bone defects seek for harmonic facial contours through surgical rehabilitation. To facilitate the maxillofacial reconstruction, there are two groups of grafts that can be used: the bone and alloplastic materials, such as the polymethyl methacrylate (PMMA), which is one of the alloplastic materials usually used by surgeons in facial rehabilitation. The aim of this study is to present a clinical report about a frontal cranioplasty using PMMA and compare its use with other materials in the literature. A male patient, 35 years old, ASA I, had a motorcycle accident, and a physical examination showed a sinking in the frontal region, deviation of right nasal dorsum and restriction of air passage through the left nostril. At the imaging examination, it was found suggestive signs of naso-orbit-ethmoid fracture and external table fracture in the middle region of the frontal bone. The patient was submitted to a surgical procedure for reconstruction of bone defect and a PMMA graft was used in the frontal bone region. PMMA is usually used because of its ease of adaptation to the bone, reduction of time of the surgery and decrease of blood loss and possibility of infection. PMMA is an attractive alternative for maxillofacial reconstructions.

Published: February 2023

Background: Globally, greater than 90% of infections in the head and neck region are of odontogenic origin. Several species of bacteria present in the mouth that exploit the circumstances of human immunity and oral hygiene to cause infections which can spread to the facial region, neck and to the rest of the body leading to serious outcome. Various bacteriological studies show variations in their conclusion. Objective: The aim of this study was to provide evidence of the most prevalent organisms involved in orofacial space infections and the most effective antibiotics for maxillofacial odontogenic infection (OMI). Material and methods: Sixty patients clinically diagnosed as OMI were enrolled in this study selected from different polyclinics from dental department at Jeddah area, Saudi Arabia. The mean age of patients was 31.4±17.26 year (35 males and 25 females). Inclusion criteria were patients with maxillofacial infections that assessed radio-graphically using periapical or panoramic views and patients had swelling intra-oral and/or extra-oral, fistula, redness, trismus, and lymphadenopathy. Exclusion criteria included patients already on antibiotics and medically compromised patients (diabetic, hepatitis, and HIV+). Results: The most commonly involved facial space was the combination of buccal and submandibular space that was involved in 46.67% of patients. While, among the entire aerobically cultured bacteria, Ciprofloxacin and Amoxicillin/clavulanic acid were the most sensitive drug with 97% and 95% of sensitivity respectively, followed by Clindamycin 88% and Cefotaxime (80%). The least effective drug was amoxicillin 18% (Table 4). While, among the entire anaerobically cultured bacteria, Metronidazole was the most sensitive drug (93%) followed by Ciprofloxacin, Amoxicillin/clavulanic acid and Clindamycin with 90%, 87% and 85% of sensitivity respectively, where Cefotaxime was 78%. Conclusion: Maxillofacial odontogenic infection (OMI) is usually poly-microbial, consisting of a complex mixture of both anaerobes and aerobes. Ciprofloxacin, Amoxicillin/clavulanic acid and Clindamycin were the most effective drugs for all isolates of OMI and the least effective drug was amoxicillin of OMI. Early surgical intervention along with selective antibiotics can stop these infections spread to deeper spaces of face and neck and hence many untoward complications can be avoided.

Objective: The purpose of this study was to assess risk factors and measure prevalence rates of Post-Traumatic Stress Disorder (PTSD) and Coping Mechanisms of migrant returnees from Middle East countries in Amhara Region, Ethiopia. Methods: Mixed method explanatory research design was employed on 376 randomly selected migrant returnees in six nominated towns of the region. PTSD checklist and Coping Strategy Indicator were employed for assessment. Focus Group Discussion (FGD) and interview were also utilized. Descriptive statistics, independent t-test and MANOVA were utilized to analyze the collected data. Result: The general life time prevalence rate of PTSD was 26.2%. Correspondingly, avoidance, intrusive thought and hyper arousal were reported core symptoms of PTSD in their due order. Likewise, to improve quality of life, failure in educational endeavor, peer and family pressure, unemployment and poverty were the major factors for migration to Middle East. In this study, the independent t-test result shows that there was statistically significant mean difference between male and female respondents in experiencing intrusive thought (t (374)=-2.62, p<0.05), avoidance (t (374)=-3.14, p<0.05) and hyper arousal (t (374)=-2.86, p< 0.05). Besides, current employment status of returnees had statistically significant effect in experiencing intrusive thought (t (374)=2.45, p<0.05), avoidance (t (374)=-2.42, p<0.05) and hyper arousal (t (374) = 2.10, p<0.05). In addition, a MANOVA result revealed that there were statistically significant differences between participants with their respective age (F (6,522)=2.230, p˂0.05), educational status (F (9,665)=3.051, p<0.05), average monthly income (F (6,522)=0.867, p˂0. 05) and types of abuse they faced (F (9,635)=2.113, p˂0. 05) on PTSD dimensions (intrusive thought, avoidance and hyper arousal). Correspondingly, ANOVA result disclosed that age, educational status, types of abuse returnees’ face and monthly income in the Middle East had statistically significant effect on intrusive thought, avoidance and hyper arousal separately. As contributing factors for PTSD, limitations on freedom of movement, enforced cultural isolation, verbal and sexual abuse, excessive working hours, being arrested, confiscation of documents, withholding of wage and life threatening trial were highly reported problems. Finally, problem solving, seeking social support and avoidance coping mechanisms were utilized in their due order. Conclusion: The life time prevalence rate of PTSD were very high. Therefore, mental health service providers shall consider in diagnosing and treating PTSD among migrant returnee
Generation of positive - negative emotional experiences and expressions through cognitive molding of drive
Authors: CR Mukundan
Published: February 2023

Drive may be identified as a psychobiological force generated within a living system, which is utilized as the fuel for driving the system in responses and actions. Cognitive processing functions of the cortical areas of the brain help mold the drive and it is experienced and expressed by the being as emotional experiences and expressions. These experiences and expressions may be molded positively or negatively based on the judgmental values of the cognitive processing. Positively molded drive initiates and executes all responses and actions in socially accepted manner and for executing actions for achieving various goals in life. When drive is utilized with negative cognitive judgments, it may be employed in negative manner and effects, with the actions and responses producing negative harmful and destructive effects to the self and others. The emotional experience itself may be mainly accompanied by similar emotional states viz., anger, fear, pain, anxiety, etc. These states of mind and expressions accompanying the drive are considered emotional experiences or expressions. Positive emotional effects, on the other hand, may be accompanied by love, affection, and respect etc. A third important emotional state is the empathy, when one learns to share the emotions experienced and expressed by others, which may be present in their behaviour and interactions. With people having diverse types of purposes and goals in life, when they may consider facilitating or debilitating the life patterns of other individuals as their noble and cherished aims of living, one may find it difficult to empathize with everyone seen or known.
Live and die - develop a mind within, while living, using which one learns to create ideas, functional systems, and knowledge; and die later, when the mind ceases to be present
Authors: CR Mukundan , C Kamarajan , P Ajayan
Published: February 2023

A few primary questions that are related to human life are about their purpose and significance, which differentiate it from other forms of life. An equally important question has always been about the nature of termination of life, which we call death. Most of the human beings used to believe that their life would continue even after death either in the heavens or a hell. Several of them still believe that this may happen, as life is a form of energy, which would continue its presence and capabilities with force forever, which cannot be dispensed or reduced to nothing. On the other hand, they do not entertain the same ideas about continuance of life in other biological or animal forms. Electromagnetic and related energy forms may function as a physical force or drive, which may have a natural presence, and which man has learnt to produce through physical and functional arrangements. They have also learnt about the presence of such force in the nature-universe, as a natural physical force in the universe, despite the absence of any living force within the nature. The most adventurous states of life are achieved by dedicating immense love to the presence of a superior force, which one believes to be present. One may have learnt to believe in the force and consider it as the supreme force of the universe, and remain highly devoted to that energy form, when the mental processing in that direction could yield almost everything a human being cherished to have in the related domain. The high drive and intense devotional affection may invariably help one carry out almost any difficult task of life, for achieving immensely enriching results. The new strength and feelings are essentially within the body and using the brain capabilities, which we call mental creations, which may become an overwhelming force and entity, surpassing the roles of a physical reality one may create. However, we still have no certainty or even clue if the life force is a form of such spiritual force or if it is only a unique physical force. What is important to know is that the presence of the exceptionally special capability for movements and for causing physical and functional changes, are capabilities present in all animals, whereas human beings could apply much higher intellectual or rational capabilities in their applications. They all need the same drive or force from the body-mind fuel for utilizing it for making movements or actions. Drive has been already identified as psycho biological source of energy or force needed for all movements, responses, and actions

Brazil is the 5th largest textile industry and 4th in the clothing segment in the world. However, its share in the global textile market is only 0.3% in terms of turnover, with a low gain in competitive capacity. Considering its importance to the Brazilian economy, this article seeks to analyze the context of the Brazilian textile industry, main concepts and a parallel with the world industry. The main results are: Brazil is a country with full capacity of farming raw materials in less harmful ways and after the pandemic, the sector started to worry more about the environment. New ways of creating the final product are already being used and the indictators show that it is possible to have a final product using less natural resources and without producing huge amounts of waste.
Sizing of pressure aeration systems for stored grain
Authors: Carvalho Lopes Daniela de , Steidle Neto Antonio José
Published: February 2023

Aeration is widely used to cool grain, preserving the physical conditions of the stored product and appearing as one of the most important practices of the postharvest sector in terms of food security. The proper sizing of the aeration system components is essential for guaranteeing the correct operation and management of this preventive technique. Either pressure or suction airflow could be used in most grain storage structures, with pressure systems being most popular. In this article, procedures required when sizing pressure aeration systems for stored grain are discussed. The main equations and recommendations for selecting the proper fan power and size are presented, aiming at allowing to deliver the adequate aeration airflow rate for grain storage during aeration. Technical information about how to calculate the dimensions of roof vents are also showed, in order to provide natural ventilation inside the storage and avoid under-roof condensation. Additionally, a methodology for calculating the dimensions of the aeration perforated ducts is proposed, aiming at suitable uniformity of airflow in the grain mass during this process. Technical and scientific information described in the literature were integrated with empirical rules and recommendations, resulting in a guideline capable of helping students and engineers that need to size pressure grain aeration systems for flat and cylindrical bins.

Introduction: The prognosis in fetal lung disease is related to the size of the pulmonary malformation and secondary pulmonary hypoplasia. The mass effect on the underlying fetal lung results in a decrease in fetal lung volume and an increased likelihood of developing respiratory distress during the neonatal period. Objectives: Estimate the lung volume cut-off points related to neonatal morbidity and mortality in fetuses with congenital pulmonary malformation measured through magnetic resonance imaging. Methodology: Analytical retrospective cohort study from July 1, 2013, to June 30, 2017. Lung volumes were measured by magnetic resonance imaging in fetuses with congenital pulmonary malformation. The different measures are described and the association of lung volume with neonatal mortality is evaluated. Results: We analyzed 26 fetuses with congenital pulmonary malformation. The mortality described was 46.1% (12/26). The mean lung volume in the group with mortality was 19.7cm3 (95% CI 12.1-27.3), vs 58.6cm3 in the group without mortality (95% CI 39.0-78.1) (p=0.0010). Average lung volumes less than 34.9 cm3 were associated with higher mortality. Conclusion: The perinatal result of fetal lung disease is related to lung volume measured with Fetal Magnetic Resonance Imaging, finding that lung volumes less than 34.9cm3 were associated with higher mortality.

Authors: Buffa Ester
Published: February 2023

This paper aims to analyze the Manual for Integral Planning of University Campus, written by Rudolph Atcon and published by the Council of Rectors of Brazilian Universities (CRUB) in 1970. It is part of a research project sponsored by CNPq, called “Architecture, urbanism and education: Brazilian university campuses”, which was coordinated by Gelson de Almeida Pinto, architect and university professor (EESC/USP), and supported by Ester Buffa, Education historian and university professor (UFSCar). This research focuses on the establishing of the first universities in the medieval Europe, in countries such as France, Italy and England. After, it shows how universities introduced the concept of University City or university campus, it means, a special city located in the country. This idea came to Brazil in the 60’s and it has influenced the planning of Brazilian universities since then. In this way, this paper relates the higher education policies, conceptions, models and theirs functions to the planning of physical space for a campus settling, that involves questions concerning architecture and urbanism.

The purpose of the study was to represent the results of the first industrial tests of the technology for processing uranium carbonate ore with a target component content of 0.3%, by selective carbonate leaching with the separation of the uranium-containing solution from the rock, in the processes of thickening and decantation with using flocculants. This study was carried out to find out more effective flocculating reagents. Experimental data were collected from industrial slurries with the addition of polyacrylamide-based flocculants. The study showed that leaching in sodium carbonate media provided a high degree of purity of the product because metals impurities during leaching did not pass into solution. In line with earlier research, the process studies have confirmed the hypothesis that replacing of low-performance disc filters with automatic settling tanks significantly reduces labor and energy consumption. The results of the study convincingly show that the scheme for processing carbonate uranium ore made it possible to reduce the time of personnel contact with toxic and radioactive products. The main technical and economic indicators of the decantation scheme are given, methods for improving the decantation washing of uranium from pulps are described. Methods for more efficient use of flocculants and reduction of their consumption are proposed. Optimal modes of the process allowed to increase productivity and reduce production costs by 10% at the expense to reduce the consumption of electricity and steam, decommission energy-intensive vacuum pumps and filters. At the same time, the average extraction of uranium in the commercial solution – 90%. The results obtained can be applied in the uranium mining industry. To increase the productivity of the decantation scheme, further tests of new flocculating reagents, methods of their introduction are necessary; it is also of practical interest to study the conditions of flocculation depending on the salt composition of the washing solutions.

The features of the distribution of toxic elements in the c1 coal seam of «Blahodatna» mine field are considered. The research aims to establish regularities in the distribution of toxic elements in the coal seam c1 of Blahodatna mine of Pavlohrad-Petropavlivka geological and industrial area of Donbas. Samples were taken from mine opening (reservoir samples, selected by the trench method and from duplicates of drill core personally). Content of toxic elements was determined by quantitative emissive spectrum analysis. The values of the main descriptive statistical indicators were calculated. With the aim of identify the composition of the geochemical associations, correlation coefficients (r) were calculated between the content of the toxic elements. In a single geochemical association united elements in which the relationship between the content is described by the correlation coefficient that exceeds 0,5, with a significance level of at least 95%. As a result of the performed studies, maps of the isoconcentrate of toxic elements and maps of the regional constituent of their contents by the area of the mine field were constructed. Linear regression equations are calculated between the concentrations of toxic elements and the main technological parameters of coal. Analyzing the result of statistical processing of geochemical information and geological and structural characteristics of the coal seam c1 of «Blahodatna» mine field allowed us to establish, that the formation of the association of cobalt, nickel, vanadium, lead, chrome and manganese is associated with the enrichment of contact zones of the coal seam by these elements and is genetically is due to influence of adsorption and reductive-oxidative barriers on the migration of matter during the diagenesis and catagenesis of coal-bearing series. The main scientific importance of the results of the performed studies is the establishment of genetic causes that have a significant effect on the distribution of toxic elements in coal seam of c1.

The first decades of the 20th century are marked with certain changes in the technologization of our society cultural development. In particular, during this time the cinematography absorbs ceaselessly – cinifies – the branches of artistic activity in the spheres of various arts. Undoubtedly, the development of cinema has one of the most perceptible effects on the theatre. It is known that the theatre art is often based on the events and plots, those are included already into the history, have a certain social resonance; its progressiveness is reduced to the systematic search for new forms of emotional spectrum transmission, the embodiment of old paintings in a new way with the use of the synthesis of various types of art. The problem of theatre cinemafication is considered as an important one in the study of the relationship between theatre and cinema. Prerequisites for the development of screen adaptations of theatrical performances include: a relatively quick and cheap method of production, the impossibility of watching theatrical productions of the country’s leading theatres in its the most remote corners. That’s why the performances have been filmed directly on the theatre stage – in a cinematic way, as well as the rapid development of television, which came to the late 1960s, the ethers of which have needed to be filled. It is just television that has given impulse to the mass production of adaptations of theatrical performances, becoming full-fledged creative achievements, using cinema and television art. The positive trend is that the theatre has become a starting point for film art, without absorbing it in any way. They continue to adopt each other’s best practices in the context of scenery, make-up, directing and script writing, musical accompaniment, but remain completely autonomous.
