The Covid-19 pandemic was and still is a great challenge for the entire world population. People in the first line, among them doctors being a very important category, faced the risk of disease and, in some cases, even became infected. The emotional consequences of this risk are highlighted in this paperwork which tries to stress, with the help of applied questionnaires, the presence of psycho-emotional disorders among the medical staff of the Oncology Department of St. Luke's Hospital, Bucharest, during the pandemic. The medical staff had a low level of stress, adapting to the evolution of the pandemic "to some extent". The main fear was that of illness and the most common emotional states experienced by the subjects were: worry, nervousness and dissatisfaction. Most of the medical staff showed negative emotions, but there were also people who felt positive emotions of relaxation, calmness or joy. The most common ways of managing the stress caused by the pandemic were: communicating with colleagues, family and friends, watching movies and enjoying various activities with the family at home.

Published: October 2021

The case was found on an organic sample consisting of the two kidneys with the renal pedicles and the corresponding segments of the abdominal aorta and inferior vena cava. From the inferior face of the left renal vein, on the lower side of the aorta, a venous branch with an upward path of 8.02 mm was detached, passing on the anterior face of the aorta, passing before its right side, in order to end on the left side of the inferior vena cava, 13.9 mm above the end of the left renal vein in the inferior vena cava, this branch thus describing a periaortic ring (necklace), in which on the left side of the aorta the inferior adrenal vein ends. The periaortic ring (necklace) had a cross-sectional dimension of 3.2 mm and a vertical one of 1.7 cm. On the right side of the aorta, a 2.9 mm venous branch came out of the renal vein, ending on the left side of the inferior vena cava, 1.2 mm above the end of the left renal vein. At the level of the right kidney there were two renal arteries, superior and inferior. Between the two arteries there was an interval of 5.1 cm.

Published: October 2021

Covid-19, also known as acute respiratory syndrome 2019-nCoV, severe acute respiratory syndrome (SARS) 2, and Wuhan pneumonia, is a viral respiratory disease caused by a SARS-associated coronavirus (SARS-CoV2). The most serious complications of Covid-19 are due to the development of micro-thrombosis in various organs and systems as a result of the high levels of pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin 1 and 6) which initiate the activation of coagulation and the generation of thrombin. Several studies demonstrated the poor outcome of Covid-19-infected patients who underwent surgery, suggesting that surgery may accelerate and exacerbate Covid-19 progression. We report the case of an 81-year-old patient admitted as an emergency with Covid-19 pneumonia, hemoperitoneum, ischemic acute cholecystitis and obstructive sigmoid cancer. Cholecystectomy, pneumoperitoneal lavage, and Hartmann operation were performed under combined epidural-spinal anesthesia. This technique has some advantages compared to spinal and epidural techniques, such as: rapid onset of analgesia and the possibility of obtaining the desired sensory level, control of the anesthetic block, and ensuring postoperative analgesia. The unfavorable outcome of this case is due to the occurrence of the cytokine storm and coagulation disorders, with the change in the related biological constants, both from a biochemical and systemic point of view.

Justicia Digital en el Derecho Disciplinario
Authors: Roa Salguero David Alonso
Published: October 2021

En la comunidad jurídica se suele confundir el concepto de justicia digital con el de trámites electrónicos. Lo primero se refiere a una solución tecnológica que le permite a las instituciones que imparten justicia incorporar trámites judiciales electrónicos en línea y con validez legal (Justicia Digital, 2020). Por el contrario, lo segundo, como se extrae de la definición anterior, son los que construyen, dan forma y contenido a la justicia digital, como la notificación y firma electrónica (Corte Suprema de Justicia, Sala Civil, Rad. 2020000230, 2020)1; esto es, toda gestión realizada dentro de la actuación disciplinaria mediante las tecnologías de la información y la comunicación (en adelante TIC).

Heat recovery technology using thermoelectric has attracted many research intentions mainly for its ability to generate power passively. The automotive engine usually produces waste heat ranging from 30-40% due to the thermodynamic limit. The use of thermoelectric generator (TEG) for waste heat recovery and power generation could increase the efficiency of the internal combustion engine system. This research developed and investigated a heat recovery system using a thermoelectric generator (TEG) for power generation. A thermoelectric generator (TEG) consisted of thermoelectric modules, hexagonal pipe connector and heat sinks was built and connected to an exhaust pipeline. A theoretical model was developed to access the thermal and electrical performance of the TEG system. The theoretical model consisted of the heat transfer mechanism including the thermal resistance networks from the flue gas to TEG and the heat sink. The electrical power output was determined using the Seebeck principle. The early stage of finding reveals that the system was able to produce an open circuit voltage of 0.13 V for a small temperature gradient of 3ᵒC between the cold and hot surface of the TEG. The further improvement of the system is currently under investigation for producing higher power. In the future, this system hopefully could replace the car battery for charging the alternator as well as increasing the overall efficiency of the engine system.

Published: October 2021

Patriotism is perceived differently. It is always important and it is the ideological basis on which the state builds its strategic goals. Our transforming society is not in a state of many existing spiritual and moral, social and political ideological trends and tendencies have finally sorted out the formation and establishment of its most affordable, efficient model. This model should facilitate a uniform and harmonious development of the whole Armenian society and its full integration into the community of civilized nations, without the loss of Armenian national identity. This article attempts to study philosophical approaches of ideological foundations of educating the society, the role and place of patriotism, as well as patriotic education in the context of these views. The article reflects the principles and particular importance of the military–patriotic education of the most active part of the society – the youth.
La Pintura De Cézanne Y La Fenomenología De La Percepción De Merleau-Ponty Como Búsqueda De La Experiencia Originaria
Authors: Soto Francisco Conde
Published: October 2021

This paper tries to clarify the coincidence between some of the main features of the characterization of perception in the phenomenology of Merleau-Ponty (Phenomenology of Perception) and the picture technique of Cézanne. Although placed in different work areas, indeed, the reflection about the perceptive act and the process of pictorical creation, there is an inspirational shared basis: Merleau-Ponty’s notion of “original experience” goes parallel to Cézanne’s understanding of the painting as a the original appearing of the things so as they should appear to a glaze that goes beyond the objectivating categories of every daily, normal perception.

Our aim is thinking death exploring several reasons of the inquiry. One can see the mystery of death like Aristotle - death is the end of sensations - but also like many others who talk about something that is presence I absence or absence /presence, or even think about the possible evil of death. But is not possible to avoid the problem of immortality or the idea that we saw ourselves like someone who says: I am nothing to the universe but everything to me.
Recepción y “Crítica inmanente” de Heidegger de la Fenomenología Husserliana
Authors: Pereña Francese
Published: October 2021

At the beginning of Prolegomena zur Geschichte des Zeitbegriffs (Gesamtausgabe, volume 20), Heidegger extensively puts forward his views against phenomenology, especially that of Husserl, which is the one we are going to consider. By means of what he calls the “fundamental discoveries of phenomenology”, that is, intentionality, categorial intuition and the meaning of the a priori in Husserl’s Logical!nvestigations, Heidegger reaches a definition of phenomenology: “the analytic description of intentionality in its a priori”. Next, Heidegger proceeds to what he characterizes as an “ immanent critique” of phenomenology, that consists in highlighting that in Ideas Husserl does make but omits the fundamental question on “the being of consciousness” and on “the sense of being”, in a way that ends up in being un-phenomenological. We go into Heidegger’ S text in order to consider the legitimacy of its critique and, particularly, its alleged immanence.

Published: October 2021

Pour élaborer son analyse existentielle, Ludwig Binswanger a utilisé la phénoménologie. Mais qu’appelait-il exactement ainsi? Sa définition de la phénoménologie et l’usage qu’il en fait ont varié, depuis la présentation aux psychiatres donnée en 1922 («De la phénoménologie»), en passant par la reprise de Heidegger à l’époque de la «Fuite des idées» (1 933), puis les critiques adressées à «Sein und Zeit» et la construction d’une anthropologie dans les «Grundformen» (1942), enfin avec 1’ ultime et étonnant tournant husserlien de «Mélancolie et Manie» (1960) et «Délire» (1965).
Pregnância Simbólica Versus Antepredicativo: O Diálogo Entre Merleau-Ponty E Cassirer
Authors: Feron Olivier
Published: October 2021

A fact ignored or underestimated by most of the specialist of the work and thought of Merleau-Ponty is the debt h is phenomenology of perception has to Ernst Cassirer’s own phenomenology. The articulation of an actual dialogue between the two thinkers is here anchored in Cassirer’s _concept of symbolic pregnance; which will have further development in Merleau’s Phenomenology of Perception, especially in the chapter he dedicated to the concept of expression. The elements of a possible discussion between the two concepts are here presented as a fruitful basis to renew the reflection on the Lebenswelt problematic.

Só o excesso é suficiente. João Paisana e a Filosofia
Authors: Heleno José Manuel
Published: October 2021

Only the excess is enough. This is our title about the relationship between João Paisana and philosophy. The main theme is phenomenology and hermeneutics, in particular the philosophy of Husserl and Heidegger. João Paisana’s reflection about these authors is very important and capable to introduce novelties. Moreover, his last writings about the concept of experience and communication, is also a very sound one. Politics, and the notion of cultures, is another vertex of his philosophy. Who knows João Paisana can recognize that there is no gap between life and philosophy.

Published: October 2021

When we reflect on 2020, especially in the United States, the divides in society amplified by the pandemic and laid bare for all to see following the murder of George Floyd in Minnesota in May, 2020 will most likely be the top of mind. We could all see this nation’s history and current complicity for racism, both the systematic and systemic. The moment was not unfamiliar, but markedly different. Initially, we wrote this piece in the summer of 2020, in response to our professional organization’s delay and hesitancy to affirm Black lives, Black students, Black engineers and Black faculty. Many of us were crying out. Allies with commitment to action showed up for and with us -- no questions asked, to ensure that what we felt was at least heard. In nearly a year since our original effort to write this piece together, some things have changed for the better. We saw our professional organization affirm Black lives. We saw some of our colleagues take action, change course and use their influence to make the community better. Some learned, listened and tried to do something new. Others, either remained silent, hopefully in contemplation, but some with a silence that convinces us that they are simply not on the same side.

We composed the below entries in the summer of 2020, amid national turbulence and internal reflection. Below we provide four personal stories and some specific calls to action situated in the summer of 2020, but these remain our aspirations and hopes for the field of engineering education.
The effect of exogenous factors on the polyenzymatic activity of RuBisCO and ATP synthase of chloroplasts from pea leaves
Authors: Semenikhin Andriy V. , Sukhovieiev Volodymyr V. , Patyka Mykola V. , Lukach Vasyl S.
Published: October 2021

Aim. To isolate and purify protein complexes – ATP synthase and RuBisCO – from pea leaf chloroplasts and study the effect of a microbiological fertilizer “Extracon” and sulfonamide inhibitors acetazolamide and ethoxyzolamide on the enzymatic activity of these proteins.Materials and methods. Chloroplasts were isolated from the leaves of two-week-old pea sprouts, protein complexes of purified thylakoid membranes were solubilized with digitonin (10 mg of digitonin per 1 mg of protein), the protein concentration was determined according to Lowry. Native electrophoresis with displacement of the charge of the soluble protein fraction from the chloroplast stroma, as well as membrane proteins, was carried out in the modified system of Anderson et al., Kolisnichenko et al. A modified Lemmley system was applied to the protein electrophoresis in the polyacrylamide gel in the presence of sodium dodecyl sulfate. The methods of Alain and Hintsik, as well as Gomorrah were used to determine the ATPase activity in the polyacrylamide gel. Visualization of the carbonic anhydrase activity in the polyacrylamide gel was performed by the method of Edwards and Petton. Results and discussion. Using physicochemical methods of potentiometry, spectrophotometry the ATPase, carbonic anhydrase and esterase activities of the enzymes were studied. The results obtained indicate that specific carbonic anhydrase inhibitors (acetazolamide and ethoxyzolamide) also block the esterase and ATPase activity of the enzyme complexes. “Extracon” (a multifunctional microbiological preparation) almost 1.5 times increases the activity of the enzymes, showing a complex activating effect of the fertilizer on both light and dark reactions of photosynthesis.Conclusions. The method of identification and isolation of RuBisCO and ATP synthase on the basis of two-dimensional electrophoresis and electrophoretic elution has been proposed. It allows determining the presence of certain enzyme activity of complexes at first in SDS plates (express analysis) and further to study the effect of various factors of endogenous and exogenous origin on the enzymatic properties of electrophoretically pure enzymes. The use of two-dimensional electrophoresis as a tool for assessing the impact of various factors of endogenous and exogenous origin on the plant cell and the plant as a whole through constant monitoring of the work and activity of enzyme systems of the plant cell is promising.

KIF13B-mediated VEGFR2 trafficking is essential for vascular leakage and metastasis in vivo
Authors: Waters Stephen B , Dominguez Joseph R , Cho Hyun-Dong , Sarich Nicolene A , Malik Asrar B , Yamada Kaori H
Published: October 2021

VEGF-A induces vascular leakage and angiogenesis via activating the cell surface localized receptor VEGF receptor 2 (VEGFR2). The amount of available VEGFR2 at the cell surface is however tightly regulated by trafficking of VEGFR2 by kinesin family 13 B (KIF13B), a plus-end kinesin motor, to the plasma membrane of endothelial cells (ECs). Competitive inhibition of interaction between VEGFR2 and KIF13B by a peptide kinesin-derived angiogenesis inhibitor (KAI) prevented pathological angiogenesis in models of cancer and eye disease associated with defective angiogenesis. Here, we show the protective effects of KAI in VEGF-A-induced vascular leakage and cancer metastasis. Using an EC-specific KIF13B knockout (Kif13biECKO) mouse model, we demonstrated the function of EC expressed KIF13B in mediating VEGF-A-induced vascular leakage, angiogenesis, tumor growth, and cancer metastasis. Thus, KIF13B-mediated trafficking of VEGFR2 to the endothelial surface has an essential role in pathological angiogenesis induced by VEGF-A, and is therefore a potential therapeutic target.
Intranasal Administration of Chitosan-Nanoparticles Conjugated with Imipramine and its Effect on Stroke-Induced Secondary Neurodegeneration: A Research Protocol
Authors: Kakar Sarthak , N. Smorenburg James
Published: October 2021

Introduction: Stroke is the second leading cause of death and the third leading cause of permanent disability worldwide. Notably, the recovery period post-stroke is crucial as there is a risk of stroke-induced secondary neurodegeneration. Stroke-induced secondary neurodegeneration is the inevitable loss of viable brain tissue at sites distal from the initial infarct. It shares similarities with neurodegenerative diseases and results in neurological deficits, further complicating stroke recovery. Intranasal administration of chitosan-nanoparticles conjugated with imipramine will be tested to determine if they elicit a synergistic effect in mitigating disease processes associated with stroke-induced secondary neurodegeneration.
Methods: Treatment and testing will be conducted in 30 male Wistar rats aged 12 months. Stroke will be induced by occluding the middle cerebral artery. Rats will be divided into three groups of 10 and will receive an intranasal dose of either saline (Control, C), 20mg/kg of imipramine (Treatment 1, T1), or 20mg/kg of chitosan-nanoparticles conjugated with imipramine (Treatment 2, T2). Statistical analysis using analysis of variance will determine if chitosan-nanoparticles conjugated with imipramine can mitigate the effects of stroke-induced secondary neurodegeneration determined by the proposed tests.
Results: T2 given 20mg/kg of chitosan-nanoparticles conjugated with imipramine is proposed to spend more time exploring the unfamiliar object in the novel object recognition test. Lesser evidence of Alzheimer’s disease in T2 is expected, as measured by the fludeoxyglucose positron emission tomography imaging. A higher serum brain-derived neurotrophic factor measured by an enzyme-linked immunosorbent assay is also expected to be present in T2.
Discussion: It is anticipated that chitosan-nanoparticles conjugated with imipramine will exhibit a synergistic effect in mitigating disease processes accompanying stroke-induced secondary neurodegeneration because of properties associated with neuroplasticity and enhanced drug targeting efficacy.
Conclusion: This research protocol aims to elucidate a novel treatment that can be applied to stroke recovery to mitigate stroke-induced secondary neurodegeneration, which tends to complicate this crucial period. Our proposal could have implications in the prognosis and management of stroke and post-stroke recovery, respectively, and inspire a framework for the discovery of novel post-stroke therapeutic interventions.

Published: October 2021

O objetivo deste trabalho é demonstrar as alterações na morfologia deltaica e no baixo curso do rio Jequitinhonha a partir da implementação barragem da Usina Hidrelétrica de Itapebi (UHI), analisando a evolução da dinâmica fluvial no baixo curso e morfologia deltaica antes e após a construção da barragem. As alterações antropogênicas na morfologia destes subsistemas permitiram interpretar dinâmicas que o rio Jequitinhonha está submetido em seu baixo curso. A caracterização, identificação e análise no delta, além do padrão de drenagem no canal principal, permitiram a investigação dos seguintes parâmetros: morfologia do canal, migração de meandros no canal fluvial, médias de vazão/precipitação e morfologia deltaica. Os resultados demonstraram o aumento da complexidade sistêmica pela intervenção antropogênica no sistema hidrográfico. Dessa forma, sugere-se que a ação antrópica promove alterações na dinâmica fluvial e consequentemente na desembocadura, estabelecendo novo equilíbrio dinâmico em resposta à construção da barragem e retificação do canal. Sugere-se que a morfologia deltaica está se alterando em curto espaço temporal, abandonando sua configuração bifurcada e transformando-se em canal fluvial único em direção à margem esquerda da desembocadura fluvial.  Changes in the low course of the Jequitinhonha river and their geomorphological impacts in the delta: the case of the Itapebi Hydroelectric Plant, Bahia, BrazilA B S T R A C TThe objective of this work is to demonstrate the changes in deltaic morphology and the low course of the Jequitinhonha River from the implementation of the Itapebi Hydroelectric Plant dam, analyzing the evolution of fluvial dynamics in the low course and deltaic morphology before and after the construction of the dam. The anthropogenic changes in the morphology of these subsystems allowed to interpret dynamics that the Jequitinhonha River is subjected to in its low course. The delta characterization, identification, and analysis, in addition to the drainage pattern in the main channel, allowed the investigation of the following parameters: channel morphology, migration of meanders in the fluvial channel, flow/precipitation averages and deltaic morphology. The results showed an increase in systemic complexity due to anthropogenic intervention in the hydrographic system. Thus, it is suggested that the anthropic action promotes changes in the river dynamics and consequently in the outlet, establishing a new dynamic balance in response to the construction of the dam and rectification of the channel. It is suggested that the deltaic morphology is changing in a short time, abandoning its bifurcated configuration, and becoming a single river channel towards the left bank of the river mouth.Keywords: Fluvial-marine Morphology; Anthropogenic Geomorphology; Geomorphological Mapping.

Apesar de ser uma área protegida, seu entorno é passível de contaminação por diversas fontes antropogênicas, principalmente ligadas a agropecuária. Objetivo principal desse estudo foi determinar os teores e a biodisponibilidade dos íons metálicos (Cr, Cu, Pb, Zn, Fe e Cd) nos sedimentos do entorno do RBSH, por meio da estração sequencial de Tessier, no verão e outono de 2019, estações climáticas que apresentaram diferentes níveis de água do reservatório. As diferenças hidrológicas entre o verão e o outono promoveram um acúmulo de alguns íons metálicos nos sedimentos e a liberação de outros para a coluna da água de uma estação para a outra. Os maiores teores de íons metálicos nos sedimentos foram detectados na fração ligada aos óxidos e hidróxidos de Fe e Mn, independente da estação climática, provavelmente devido à origem basáltica dos solos da região. No entanto, nenhum dos íons metálicos ultrapassou o valor do PEL (nível de efeitos prováveis), indicando que apenas ocasionalmente são esperados efeitos adversos à biota. Os indicadores de qualidade dos sedimentos mostraram uma contaminação moderada por Cr e Pb, em virtude de contribuições antropogênicas.     Metal speciation in surface sediments of a conservation unit: Biological Refuge of Santa Helena – Paraná A B S T R A C TThe Santa Helena Biological Refuge (RBSH) is a conservation unit bathed by the Itaipu reservoir, in western Paraná, Brazil. Despite being a protected area, its surroundings are susceptible to contamination by several anthropogenic sources, mainly linked to agriculture and livestock. The main objective of the study was to determine the levels and bioavailability of metal ions (Cr, Cu, Pb, Zn, Fe and Cd) in the sediments surrounding the RBSH, through the sequential Tessier extraction, in the summer and autumn of 2019, which different levels of water in the reservoir. The hydrological differences between summer and autumn promoted the accumulation of some metal ions in the sediments and the release of others to a column of water from one season to the next. The highest levels of metal ions in the sediments were detected in the fraction linked to the oxides and hydroxides of Fe and Mn, regardless of the climatic season, probably due to the basaltic origin of the soils in the region. However, none of the metal ions exceeded the PEL value (level of probable effects), indicating that only occasionally adverse effects to biota are expected. The differentiated sediment quality indicators show moderate contamination by Cr and Pb, due to anthropogenic contributions.Keyword: sediments, metal ions, speciation, sequential extraction

As variações da linha de costa podem ocasionar prejuízos para o desenvolvimento do Estado e para projetos de engenharia. Dessa maneira os planos de gerenciamento costeiro devem levar em consideração as informações referentes ao posicionamento da linha de costa no passado para entender o comportamento atual e futuro. Neste contexto, esse presente estudo teve por finalidade analisar o comportamento da linha de costa em resposta a dinâmica natural e as ações antrópicas no município de São Gonçalo do Amarante, no estado do Ceará, através de análise multitemporal de imagens de satélite da série Landsat em um intervalo de 36 anos (1984-2020) com auxílio da extensão DSAS do software ArcGis por meio do método Linear Regression Rate. Na qual, foi possível interpretar duas fases bem marcantes: durante a construção do porto, marcado pela ação intensa da erosão que ocasionou diversos prejuízos ambientais e, após a construção do porto, manifestou-se os processos deposicionais. Dessa forma, esse estudo enfatiza que o município de São Gonçalo do Amarante, tem sofrido alterações na dinâmica local costeira e afetado a capacidade natural dos sistemas em responder efetivamente a eventos climáticos extremos, tornando assim essas regiões mais vulneráveis.      Analysis of the evolution of the coast line in the municipality of São Gonçalo do Amarante/CE in the period from 1984 to 2020A B S T R A C TVariations of the coastline can cause losses for the development of the State and for engineering projects. Thus, coastal management plans should take into account information regarding the positioning of the coastline in the past for current and future behavior. In this context, this study has to analyze the behavior of the coastline in response to natural dynamics and anthropic actions in the municipality of São Gonçalo do Amarante, in the state of Ceará, through multitemporal analysis of Landsat series satellite images in a 36-year interval (1984-2020) with the aid of the DSAS extension of the ArcGis software. In which, it was possible to interpret two very striking phases: during the construction of the port, marked by the intense action of erosion that caused several environmental damages and after the construction of the port, the depositional processes that have led the local sedimentary balance to balance. Therefore, it is essential to monitor the evolution of the coastline, as it will generate essential information to understand the local coastal dynamics and how it influences the natural environment.Keywords: Coast line, Port of Pecém, DSAS, coastal dynamics.

Al fin a finales del año 2020, llegó la vacuna contra el COVID-19. No fue una sorpresa ya que varias farmacéuticas la habían prometido para esta fecha y cumplieron. Ladesarrollaron en un tiempo récord de menos de un año. Normalmente una vacuna tarda más tiempo en ponerse a punto, de 2 a 10 años. Pero en este caso, por la presión de la pandemia, las farmacéuticas liberaron la vacuna con los primeros resultados de losensayos de fase III. Cuando comenzó a aplicarse se generó una polémica debido a la negativa de muchas personas a aplicársela. Están también los místicos que, por razones esotéricas, no quieren ser vacunados. Estas posiciones extremas están alejadas de la realidad de la vacunación. En el mundo moderno el ser humano es vacunado prácticamente desde que nace para neutralizar una multitud de enfermedades. Así que el cuerpohumano en general está acostumbrado a recibir vacunas, los esquemas de vacunaciónson tan importantes para el humano moderno, que prácticamente se podría decir que, si no fuera por las vacunas, aún la civilización estaría en la edad media.
