Authors: González Córdoba Marcela , Chará Julián , Zúñiga María Del Carmen , Giraldo Lina Paola , Ramírez Yuly Paulina
Published: July 2020

Introducción: Los élmidos son organismos acuáticos frecuentemente asociados con aguas corrientes, limpias y bien oxigenadas. Sin embargo, algunos géneros de esta familia también se encuentran en aguas moderadamente contaminadas, lo cual puede ser un reflejo de su tolerancia al deterioro del hábitat. Objetivos: Con el fin de determinar los principales factores que influyen en la presencia de Elmidae en microcuencas colombianas, Métodos: se muestrearon 60 localidades en seis ventanas entre 450 y 4000 msnm, principalmente en la región Andina. Se hicieron arrastres con red D y Surber y se determinaron los géneros de Elmidae. Se tomaron datos físico-químicos, bacteriológicos y de calidad del hábitat (ICH). Se calcularon los Índices de Contaminación y Calidad de Agua (ICA-FSN e ICOs), se realizó un Análisis de Correspondencia Canónica entre las variables ambientales y la composición de Elmidae y se definieron intervalos para cada género. Resultados: Se encontraron 22 géneros que representan el 85% de la riqueza nacional conocida. Los principales factores que influyeron en la riqueza y composición de Elmidae fueron: saturación de oxígeno, deposición de sedimentos, cantidad de sólidos en suspensión, disponibilidad de sustratos para colonización y la ubicación geográfica. Conclusión: Con esta información fue posible clasificar los géneros de Elmidae por su sensibilidad y relacionarlos con la calidad del agua y el hábitat en microcuencas de Colombia.
The Dissipative Properties Assessment of the Oscillatory System of a Serial Sample of the Coriolis Flowmeter
Authors: Romanov V. A , Taranenko P. A
Published: July 2020

The quantitative estimates of the flow rate (or density) of the flowing fluid obtained by the measurements using the industrial Coriolis flowmeters are made by using the laboratory experiments previously performed with the exemplary sensor. In this case we face two limitations, such as the unavailability of the facilities because of intense laboratory schedules and little time to upgrade the sensor oscillatory system. So we suggest using the virtual prototyping approaches as an alternative to the descriptive approaches. One of the fundamental problems of creating a virtual prototype of the Coriolis flowmeter is to separate the main parameter measured by the flowmeter (the phase shift) into the parts connected to the gyroscopic and dissipative forces. To solve this problem, we need to identify the dissipative forces model of the flowmeter oscillatory system. The article discusses the experimental results determining the dissipative properties of the mechanical oscillatory system of one of the commercially available Coriolis flowmeter samples. The algorithm identifying the model of the dissipative properties of the flowmeter oscillatory system is based on studying the nonlinearity degree of the envelope of the vibrogram of free damped oscillations. The experiments were carried out at the pouring stand of the Center for Experimental Mechanics of the South Ural State University, which allows controlling the speed and phase composition of the fluid flowing through the flowmeter. The article describes the processing algorithms for vibrograms of the damped oscillations, which make it possible to isolate the contribution into the dissipated energy from the dry (Coulomb model), the linear viscous (Rayleigh model) and quadratic viscous friction. The pronounced dependence of the vibrational system dissipation of the Coriolis flowmeter on the features of the fluid flow (velocity, mode: continuous, slug) was experimentally proven, the solutions of identifying the model of the dissipative forces are presented.

Objective: The article measures the efficiency of higher education didactic activities using a non-radial SBM model with weight restrictions. The analysis was performed on two levels, from the analysis of 59 public higher education institutions in Poland and 18 faculties of the Warsaw University of Technology in 2014.Research Design & Methods: A non-radial SBM model with weight restrictions (Slack Based Measure Assurance Region, SBM-AR) was used to assess efficiency.Findings: The results of the study indicate that, irrespective of the research assumption, only the Jagiellonian University in Kraków, Gdańsk University of Technology and Wrocław University of Technology, in the case of universities, and the Faculty of Electronics and Information Technology and the Faculty of Materials Science at the Warsaw University of Technology proved to be fully efficient units in all models and research approaches. Eight universities and three faculties were not fully efficient, though they were efficient in some respects.Implications / Recommendations: Imposing restrictions on the SBM weights made it possible to reduce the excess number of efficient universities present in the classical approach.Contribution: The study proves that adopting the appropriate DEA model determines the results of unit efficiency. Therefore, different models should be used in conjunctions with a comprehensive performance assessment based on them.

Background

For the prevention of chemotherapy-induced nausea and vomiting (CINV) during the delayed phase (24–120 hours) after moderately emetogenic chemotherapy (MEC), the use of 3-day dexamethasone (DEX) is often recommended. This study compared the efficacy and safety of two DEX-sparing regimens with 3-day DEX, focusing on delayed nausea.

Patients and Methods

This open-label, randomized, phase III study was designed to demonstrate noninferiority of two DEX-sparing regimens: ondansetron + DEX on day 1 + metoclopramide on days 2–3 (MCP arm), and palonosetron + DEX on day 1 (PAL arm) versus ondansetron on day 1 + DEX on days 1–3 (DEX arm) in chemotherapy-naïve patients receiving MEC. Primary efficacy endpoint was total control (TC; no emetic episodes, no use of rescue medication, no nausea) in the delayed phase. Noninferiority was defined as a lower 95% CI greater than the noninferiority margin set at −20%. Secondary endpoints included no vomiting, no rescue medication, no (significant) nausea, impact of CINV on quality of life, and antiemetics-associated side effects.

Results

Treatment arms were comparable for 189 patients analyzed: predominantly male (55.7%), median age 65.0 years, colorectal cancer (85.7%), and oxaliplatin-based chemotherapy (81.5%). MCP demonstrated noninferiority to DEX for delayed TC (MCP 56.1% vs. DEX 50.0%; 95% CI, −11.3%, 23.5%). PAL also demonstrated noninferiority to DEX (PAL 55.6% vs. DEX 50.0%; 95% CI, −12.0%, 23.2%). There were no statistically significant differences for all secondary endpoints between treatment arms.

Conclusion

This study showed that DEX-sparing regimens are noninferior to multiple-day DEX in terms of delayed TC rate in patients undergoing MEC. ClinicalTrials.gov  identifier. NCT02135510.

Implications for Practice

Chemotherapy-induced nausea and vomiting (CINV) in the delayed phase (24–120 hours after chemotherapy) remains one of the most troublesome adverse effects associated with cancer treatment. In particular, delayed nausea is often poorly controlled. The role of dexamethasone (DEX) in the prevention of delayed nausea after moderately emetogenic chemotherapy (MEC) is controversial. This study is the first to include nausea assessment as a part of the primary study outcome to better gauge the effectiveness of CINV control and patients’ experience. Results show that a DEX-sparing strategy does not result in any significant loss of overall antiemetic control: DEX-sparing strategies incorporating palonosetron or multiple-day metoclopramide are safe and at least as effective as standard treatment with a 3-day DEX regimen with ondansetron in controlling delayed CINV—and nausea in particular—following MEC.
Lateral response of rigid monopiles subjected to cyclic loading: centrifuge modelling
Authors: Li Qiang , Askarinejad Amin , Gavin Keneth
Published: July 2020

In this study, a total number of 20 centrifuge tests were carried out to investigate monopile behaviour under lateral cyclic loading. The instrumented model pile simulates an offshore wind turbine foundation with an embedment ratio of 5 installed in sand layers with two relative densities of 80% and 50%. The influence of the directional characteristic and amplitude of cyclic load on pile lateral behaviour was studied. The data analysis focused on the influence of cyclic load on the accumulation of lateral displacement and evolution of secant stiffness of the foundation system. The most damaging cyclic load type (which can cause the most accumulated pile displacement) is identified as two-way loading, and it was observed that cyclic load always increases the pile secant stiffness. A new model for the prediction of evolution of accumulated displacement and change in secant stiffness has been formulated. An example of the procedure developed is presented for a typical field monopile subjected to cyclic loading. Lastly, the performance of the new model is demonstrated and predicted results are compared with field test data.
Análise comparativa da gestão da comunicação corporativa em empresas e instituições: o caso da Galiza
Authors: Costa-Sánchez Carmen , Túñez-López José Miguel , Míguez-González María Isabel
Published: July 2020

O estudo da comunicação enquanto atividade profissional é frequentemente conduzido no contexto de grandes organizações com múltiplos recursos, principalmente em empresas. Esta investigação vem contrariar essa tendência e compara departamentos de comunicação de organizações públicas e privadas, que se situam numa área geográfica afastada dos núcleos socioeconómicos e políticos de Espanha: a Comunidade Autónoma da Galiza.  Na Europa, têm vindo a realizar-se alguns trabalhos importantes sobre a prática da comunicação organizacional (Zerfass, Verhoeven, Moreno, Tench & Vercic, 2020), tal como em Espanha (Dircom, 2015), os quais se converteram em referências relevantes para o conhecimento das tendências aplicadas à gestão da comunicação. Ainda assim, as análises que se debruçam sobre organizações de pequena dimensão ou afastadas dos centros de decisão são escassas. A presente investigação pretende preencher esta lacuna ao incidir sobre organizações com diferentes perfis e dimensões, sediadas na Comunidade Autónoma da Galiza. A metodologia aplicada, de carácter quantitativo, privilegiou a realização de inquéritos a responsáveis de comunicação de organizações públicas e privadas galegas. Os resultados obtidos mostraram que o setor público é aquele que mais usa a comunicação enquanto estratégia e esta é uma conclusão capaz de suscitar o interesse para trabalhos futuros.

Published: July 2020

A partir de notícias que anunciaram número de assassinatos por intervenção do Estado e óbitos presentes em maioria nos casos de Covid-19 no Brasil, inúmeros artistas disponibilizaram seus ritmos para denunciar o “pacto narcísico da branquitude” e suas engrenagens de silenciamento da violência, tortura e genocídio do povo preto. O presente artigo busca demonstrar a partir de uma perspectiva decolonial como as/os poetas pretas/os explicitam a reinvenção de corpos em meio ao luto cotidiano provocado pela necropolítica. Foram eleitos o “Instagram” e “Youtube” como território-pista, para que fossem analisados alguns dos poemas que compõem esse artigo. As poesias selecionadas foram as que apresentaram maior circulação no dia determinado. Concluímos que o poeta-opositor é um armado em disputa pelo sentido da vida. Suas rimas alcançam todos os cantos, são manifestações calorosas de contramemória, circulando por entre as corporificações que o fazem trafegar na atmosfera do mundo, produzindo subjetividade.
The Relevance of Simmel’s Sociology
Authors: Rammstedt Otthein
Published: July 2020

Otthein Rammstedt was an outstanding sociologist who spent most of his life editing Georg Simmel’s Gesamtausgabe, or collected works. Rammstedt gave much of his strength and energy to get this important publication completed. In 1993, to commemorate the 75th anniversary of Simmel’s death, we put together a selection of his works and the articles written in his honor which was published in 1994 in the second issue of the Sociological Journal. Rammstedt then provided us with his manuscript on Simmel which we are going to republish in the Sociological Education section of our quarterly. His manuscript deserves to be published anew, not just for sad reasons — in the last issue, we announced that Ramstedt passed away after having completed his huge body of work — but also for reasons that are quite substantial. Classical sociology may seem to be a completed project, but it is still a resource that has not been fully exhausted or fully evaluated. The article by Rammstedt, who was experienced not only in the history of sociology but in its theory as well and was the long-term dean of the Faculty of Sociology in Bielefeld University, one of the most renowned sociological institutions in Europe, allows us to see how much we can take from the legacy of the classics. His text has obviously retained its considerable suitability, but, like many classical sociological writings, it needs a new revision or even perhaps a new translation. In any case, we hope this publication will give a new impetus to the study of Simmel’s writings as well as of sociological classics, while at the same time paying a debt of gratitude to the prominent German sociologist, Otthein Rammstedt

Access to Housing and Social Inclusion in a Post-Crisis Era: Contextualizing Recent Trends in the City of Athens
Authors: Maloutas Thomas , Siatitsa Dimitra , Balampanidis Dimitris
Published: July 2020

The way housing affordability evolved since WW2 in Greece—and in its capital city in particular—is an example of how the South European welfare system managed, for several decades, to provide socially inclusive housing solutions without developing the services of a sizeable welfare state until global forces and related policies brought it to an end. The increased role of the market in housing provision since the 1980s, the rapid growth of mortgage lending in the 1990s, the neoliberal policy recipes imposed during the crisis of the 2010s and the unleashed demand for housing in the aftermath of the crisis have led to increased housing inequalities and converged the outcome of this South European path with the outcome of undoing socially inclusive housing solutions provided by the welfare state in other contexts. The article follows longstanding and recent developments concerning the housing model in Greece and especially in the city of Athens, focusing on mechanisms that have allowed access to affordable housing for broad parts of the population during different historical periods, and examines the extent to which the current housing model remains inclusive or not. The aim here is to discuss the most important challenges concerning access to decent housing and highlight the need for inclusive housing policies to be introduced into the current social and political agenda.
Who’s Homeless and Whose Homeless?
Authors: Sahlin Ingrid
Published: July 2020

What does the persistent construction of ‘the homeless’ and the revitalised term ‘our homeless’ include, imply, and exclude in Swedish political debate? And how is it politically and morally related to other houseless groups in the country? These questions are approached through an analysis of minutes from the Swedish Parliament 2015–2019. Inspired by Simmel’s (1908/1965) definition of ‘the poor’ as those who get (or would get) public assistance as poor, I claim that in Swedish political discourse, ‘(our) homeless’ comprise only those to whom the society acknowledges a responsibility to give shelter, thereby excluding the tens of thousands of people without homes that are temporarily accommodated by other authorities, private providers or individuals—or not at all. Although official definitions are housing-related, migrants without homes tend to be defined outside the ‘homeless’ concept, as well as from the municipalities’ responsibilities. I will argue that the reasons for this are institutional: regulations and their interpretation, coupled with traditions to care for only ‘our’ people which, in turn, are fortified by current nationalist sentiments.

Published: July 2020

The determination of the copolymers of 4-vinylpyridine with styrene copolymers real composition, formed under the conditions of precipitation copolymerization in CCl4, is described. For this, 4-vinylpyridine with styrene was copolymerized in different ratios. The composition of the obtained copolymers was determined according to 1H NMR spectroscopy. A comparison of the real copolymers composition with the theoretically calculated ones was performed as well. The copolymerization of styrene with 4-vinylpyridine was carried out in sealed ampoules in argon medium. Solutions of a concentration of 1.02 mol/l in CCl4 were prepared. The initiator azobisisobutyronitrile in the amount of 0.00106 mol/l was added. The copolymerization was carried out in a thermostat C1823 at T = 75 ± 0.5°C. The copolymerization time was 3 hours. The original ratio of monomers (4-vinylpyridine:styrene) = 6:1; 5:1; 4:1; 3:1; 2:1; 1:2; 1:3; 1:4; 1:5; 1:6. The composition of the obtained copolymers was determined according to 1H NMR spectroscopy. It was determined that copolymers of 4-vinylpyridine with styrene obtained by precipitation copolymerization in CCl4 were enriched by 4-vinylpyridine bonds. On the contrary, the calculation of the instant composition of the copolymers according to the literature shows that under the conditions of classical copolymerization in 4-vinylpyridine solution is less active than styrene. We calculated the theoretical relative constants of copolymerization of styrene with 4-vinylpyridine: r1 = 1.97; r2 = 0.93. Therefore, under the conditions of classical copolymerization in solution 4-vinylpyridine is less active than styrene (r2 < r1). It was also found out that for the original molar content of styrene if it is greater than 0,85, it is not possible to synthesize by means of precipitation polymerization into CCl4 the copolymers of 4-vinylpyridine:styrene.
THERMOSTABILITY OF POLYSTYRENE BY STYRYLQUINOLINE CONTAINING METHACRYLATES
Authors: Kharchenko O. , Smokal V. , Krupka O. , Kolendo A.
Published: July 2020

It's known that polystyrene is one of the most widely used plastics. The materials based on it are used in almost all branches of engineering and human's daily life. Therefore, the creation of new highly effective thermal stabilizers for polystyrene remains as the actual task of polymer chemistry. Combining fragments of basic industrial monomer with the modifiers in the polymer matrix provides the ability to control performance properties of obtained materials. Investigation of thermostabilitive action of new styrylquinoline containing methacrylic monomers on polystyrene have been described in this work. Polystyrene and copolymers based on styrene and new methacrylic styrylquinoline containing monomers were synthesized by free radical thermoinitiated polymerization. 2,2´-Azo-bisisobutyronitrile (1 mass per cent) was used as initiator. Styrylquinoline monomers (3 mol per cent) were added to styrene for making modified samples. Polymerization was carried out by heating of reactants in ethyl acetate during 16 hours. Polymers were precipitated in isopropanol and dried at vacuum. The impact of such dopants – 2-[2-(4-methoxyphenyl)ethenyl]quinolin-8-yl 2-methylpropyl-2-enoate (М1), 2-(2-phenylethenyl)quinolin-8-yl 2-methylpropyl-2-enoate (М2), 2-[2-(4-nitrophenyl)ethenyl]quinolin-8-yl 2-methylpropyl-2-enoate (М3) were investigated. Thermostability of polystyrene and modified samples styrene:M1, styrene:M2, styrene:M3 were studied by dynamic thermograviametric analysis. It was shown that destruction of polystyrene with dopants M1-M2 starts at 41–42°С higher than reference polystyrene prepared at the same conditions and polystyrene of brand STYRONE (Switzerland). Sample with dopant M3 begins destruction with lower speed than reference polystyrene. First one loses 20% of weight at 347°С while reference polystyrene loses 50% of weight. It means, that dopant M3 can act as retarder of thermal destruction of polystyrene. It was found that new monomers have thermal stabilizing effect after its covalent introducing and can act as effective inhibitors of thermodestruction of polystyrene in the air.
TWO ANNIVERSARIES (THE VALUE OF A. A. GUSEV AND V. A. SNETKOV FOR THE ESTABLISHMENT AND DEVELOPMENT OF FORENSIC PORTRAIT EXAMINATION)

ORGANIZATION OF PORTRAIT EXPERTISE IN THE DIGITAL SPHERE
Authors: Podvolotski I. N.
Published: July 2020

Digital space and Informatization penetrate various layers of social life. Experts use a wide range of information in their professional activities, but many expert methods are still based on a sensory-rational methodological basis. In the fi eld of legal proceedings, information is considered in a broad aspect, it acts as an object of encroachment, a means of committing off enses, information about the incident and suspected persons. For the expert, the main sources of information are data (information) obtained in accordance with the established regulations. By analogy with the procedural regulations, when presenting material evidence, the investigator sends the expert a material carrier with information that must fi rst be extracted from the carrier itself, and then conduct a study and analysis to determine the potential for solving expert problems. To some extent, the procedural rules can ensure the reliability of the material carrier, but it is diffi cult to guarantee that the information contained on it was not subjected to deliberate or accidental distortion. The article proposes to consider separate organizational approaches to improving methodological recommendations for working with electronic portrait images and focuses on legal and technological support for the reliability of information presented in digital form. It is no exaggeration to say that the challenges associated with the spread of computer technologies give a new dimension to the development of forensic science. Today, a space of fundamentally new opportunities opens, the use of which will largely allow us to reformat research methods.

Chatter prediction based on operational modal analysis and an adaptive complex Morlet filter
Authors: Yang Kai , Wang Guofeng , Ma Kaile
Published: July 2020

Chatter that occurs between a cutting tool and a workpiece greatly reduces the surface quality and production efficiency. Therefore, it is of great importance to predict and avoid chatter so as to guarantee the stability of the manufacturing process. To realise the accurate prediction
of the stability boundary of machine tools, operational modal analysis (OMA) is increasingly receiving attention due to its adequate consideration of variations in working conditions in the industrial environment. However, because of the influence of harmonic components in the response signals,
the accuracy in identifying the modal parameters is seriously compromised. In this paper, an adaptive complex Morlet filter (ACMF) is presented to remove the harmonic components by adaptively adjusting the centre frequency and bandwidth according to the local character of the ambient environment
in a specific frequency range and filtering out harmonic components that are not strict integer multiples of the fundamental frequency owing to non-rigid periodic motion of the machine tool spindle. In order to show the effectiveness of the proposed method, milling experiments are carried
out and experimental modal analysis (EMA) is utilised to make comparisons with the proposed method. Moreover, comparisons between the ACMF and two other typical filtering methods are made. The results indicate that the proposed method performs well in modal parameter recognition for machine
tools.
Outcome of pregnancy in previous caesarean section: an observational study
Authors: Thobbi Vidya A. , Zeba Syeda
Published: July 2020

Background: Presently, good obstetrics means an uncomplicated antenatal period, labour and puerperium for the mother and birth of a healthy body. Post caesarean section pregnancy has now become one of the most common high-risk cases tackled at any hospital. In this paper an attempt has been made to assess the outcomes of pregnancy in previous caesarean section.Methods: This study was conducted among patients in the department of gynecology and obstetrics at Al-Ameen Hospital from June 2016 to December 2018. For that purpose, a sample size of 100 was considered. Data were analyzed using SPSS software v. 23.0. and Microsoft office 2007.Results: The incidence of caesarean section was 10.25%. Anaemia, pregnancy-induced hypertension and diabetes mellitus found in this study is more coincidental. Placenta previa cases were also present. Cephalopelvic disproportion was the commonest indication of the previous section in this study. 20% of the cases have had their previous section due to cephalopelvic disproportion. 18% of the cases had delivered vaginally, 15 cases were delivered by forceps (72.2%) and 3 cases were delivered normally (27.8%). Maternal morbidity was found to be low and there was no maternal death.Conclusions: The patient whose primary section was done due to cephalopelvic disproportion should be assessed thoroughly in her current pregnancy before placing her to elective repeat section. As there is always the possibility of scar rupture in a case of post caesarean section pregnancy one must think twice before doing the primary section. More research is required to evaluate optimum time of management.

Water is an important resource for life and as such, its monitoring is essential. The aim of this study therefore was to estimate concentrations of chlorophyll-a and total suspended solids (TSS) using orbital remote sensing data. The study area was the General Sampaio reservoir, located in the Curu River Basin, in the state of Ceará. The concentration of chlorophyll-a and sediments were mapped based on orbital images captured by the Operational Land Imager (OLI) sensor. The images were acquired on 14 September 2017 and 13 June 2018. The chlorophyll-a concentration was estimated using a model employing a ratio of the blue (450-510 nm) and green (530-590 nm) bands, and the TSS concentration was estimated from the red band (640-690 nm) of the OLI sensor. The chlorophyll-a concentration in September 2017 varied from 37.03 to 43.0 mg L-1, and in June 2018 it ranged from 42.9 to 62.2 mg L-1. The TSS concentration in September 2017 varied from 1.8 to 4.2 mg L-1, while in June 2018, a period that corresponded to the highest local rainfall, the variation was greater, between 2.1 and 17.73 mg L-1. The highest concentrations of suspended sediments were seen in the tributaries of the Curu River and the Salvação Stream. It was possible to estimate the concentrations of chlorophyll-a and TSS using orbital images. The reservoir water was classified as eutrophic throughout the study period.

Published: July 2020

O presente artigo parte do desenvolvimento teórico de uma Economia Política da Comunicação voltada aos estudos do Jornalismo para analisar as mudanças na cobertura esportiva midiática nos últimos anos, tendo como objeto de análise as mudanças no jornalismo esportivo do Grupo Globo, das questões estruturais do setor no conglomerado ao contrato com Neymar Júnior, vigente nos anos de 2014 e 2015. Mais que um legado comunicacional da Copa do Mundo FIFA Brasil 2014, esse fato representa o ápice das mudanças da cobertura esportiva cada vez mais voltada ao entretenimento que ao jornalismo.
Corioepitelioma

Published: July 2020

Las características biológicas y fisiopatológicas del corioepitelioma son de sumo interés y deben ser resumidas para sentar una base diagnóstica y seguir una conducta apropiada en su tratamiento. No se puede prescindir al estudiarlo de la mola hidatidiforme ni olvidar su substractum histológico: el trofoblasto. Conviene recordar además su curiosa situación de tumor parásito, huésped del organismo qu¡e lo sufre.El corion primitivo o trofoblasto formado por una capa de células (el blastocito o vesícula blastodérmica) se diferencia en dos capas formando el citotrofoblasto o capa de Langhans y el sincitio de Sertolli.
Lactancia normal y anormal

Los senos han sido considerados por tiempo inmemorial como símbolo que refleja la capacidad de maternidad en la mujer.El tamaño de los senos, por otra parte, en el cual la mayoría de las mujeres basan sus atributos maternales, no está de acuerdo siempre, con sus capacidades de lactancia.Hoy día, debido a las facilidades de alimentación artificial en algunos países del mundo, ha hecho que los especialistas contemplen con indiferencia los diferentes problemas de lactancia.Los valiosos conocimientos de lactancia de que actualmente disponemos, son el fruto de 36 años de investigaciones llevadas a cabo por el profesor Charles W. Turner, de Columbia. Missouri. Estados Unidos, así como también de más de dos décadas de investigación realizadas por el profesor S. J. Folley y colaboradores, de Shinfield. Berkshire, Inglaterra.
Patología placentaria en la etiología eclámpsica
Authors: Merlano Merlano Victor
Published: July 2020

En los últimos años la etiología de la toxemia se ha enfocado desde dos puntos de vista: primero por el hallazgo de necrosis placentaria y segundo por la influencia del espasmo vascular.En 1930 R. A. Bartholomew descubrió en la cara materna de la placenta, áreas de degeneración reciente, especialmente en casos de “Abruptio”. El hallazgo sugería más la causa que el efecto, ya que representaba tejido degenerado en contacto con la corriente sanguínea materna intervellosa; por lo tanto con posibilidad de diseminar en la circulación general de la madre productos tóxicos residuales.
Comentario al trabajo sobre la aplicación del método psicoprofiláctico en Medellín
Authors: Fernandez-Bastidas M. A.
Published: July 2020

El trabajo presentado al “Primer Simposio Colombiano sobre Parto Indoloro” celebrado en Bogotá, por los doctores G. Isaza Mejia, J. Muñoz Moreno y L. Rodríguez, es un estudio metódico que da a cabalidad una idea precisa sobre los resultados obtenidos por los autores a través de dos años y medio de su aplicación en la clientela privada en la ciudad de Medellin (Colombia).El plan de conferencias seguido calca punto por punto el plan esbozado por F. Lamaze y colaboradores de la Clínica de los Metalúrgicos de París; salvo lo referente a la primera conferencia, en la cual, a manera de introducción, enfoca el aspecto religioso con la lectura de la carta del Papa Pío XII, factor que se ha tenido también muy bien cuenta en nuestras pacientes de la Clínica de Palermo, de Bogotá, por parecer ineludible tratar el punto (sentencia bíblica) con pacientes de gran sentido religioso, como son la gran mayoría de las mujeres colombianas.
Precocidad sexual en la mujer
Authors: Hamblen Edwin C.
Published: July 2020

Debe definirse con claridad en primer lugar lo que entendemos por precocidad sexual. Es un adelanto sexual definitivo en el que aparecen en la edad prepuberal todos los cambios sexuales, como desarrollo de los senos, aparición de vello pubiano y axilar, repartición ginecoide de la grasa, menstruación, etc., al tiempo con un aumento definido en la edad ósea y dental, y aumento precoz de la estatura corporal.No deben entenderse como casos de precocidad sexual aquellos en que se encuentran reacciones focales aisladas, como el hirsutismo esencial, la pubarquia idiopática (aparición de vello pubiano), la telarquía idiopática (desarrollo precoz de los senos), cuando no coexisten con el aumento de la edad dental y ósea.Sentada esta definición, podemos clasificar la precocidad sexual en la mujer en tres tipos generales. No creemos necesaria una clasificación etiológica.

La Clínica de Maternidad “David Restrepo” de Bogotá comenzó a aplicar el método psicoprofiláctico para el parto indoloro en enero de 1959, cuando se preparó un grupo de sesenta pacientes. En marzo, por invitación de la clínica, vino a Bogotá el doctor Pierre Vellay, quien dictó una serie de conferencias sobre el método. El interés suscitado por esta visita se comprende por ser el doctor Vellay una de las personalidades más destacadas en la obstetricia francesa, discípulo del doctor Fernand Lamaze y continuador de su obra, que es adelantar y difundir el parto sin dolor fundado en un conocimiento científico de la fisiología de la corteza cerebral, sobre las bases establecidas por la escuela de I. P. Pavlov.
Amenorrea premenárquica síndrome de gonadas rudimentarias
Authors: Hambien Edwin C.
Published: July 2020

Vamos a tratar hoy del tema de la amenorrea inicial, es decir, de la amenorrea en la mujer que nunca ha tenido reglas. No soy partidario de la conocida clasificación de amenorreas primarias y secundarias, porque me parece que se presta a ambigüedades, y unos la toman en el sentido cronológico para determinar que la amenorrea primaria es la de la mujer que nunca ha tenido reglas, y la secundaria es la de la mujer que ha tenido reglas y deja de tenerlas, y otros la toman en sentido etiológico para expresar que la primaria es cuando la deficiencia es primitiva del ovario, y la secundaria es por causas extra-ováricas. Por esta razón he creado los términos de amenorrea premenárquica y amenorrea post-menárquica. que se definen por sí solos.

Актуальность исследования подтверждается высоким потенциалом результативности подхода к решению экологических проблем на основе объединения усилий государства, бизнес-сообщества и граждан. Если в странах ОЭСР давно уделяется пристальное внимание данному подходу, то в России инициативы такого рода набирают силу только в последние годы. Предметом исследования является влияние уровня образования и возраста человека на степень выраженности его экологического самосознания. Объектом исследования выступают результаты международных исследований и социологического опроса, а также лучшие практики, ориентированные на повышение экологического самосознания граждан. Цель исследования заключается в выявлении ключевых факторов, определяющих уровень экологического самосознания населения в контексте перспектив их применения в России. Методы: анализ статистических данных, сравнительные оценки, социологический опрос, неструктурированное интервью с представителями российского экологически ориентированного бизнес-сообщества. Результаты: проведено сравнение влияния уровня образования и возраста на экологическое самосознание граждан ОЭСР, выявлены межстрановые различия в данных оценках, по результатам социологического исследования определено влияние уровня образования и возраста респондентов на экологическое самосознание граждан в нашей стране, осмыслены актуальные корпоративные инициативы по формированию экологического самосознания, сделаны выводы о перспективах их развития в России.

Sentido y maldad

"El presente artículo busca comprender cómo las acciones de los hombres marcan de manera significativa nuestras realidades más particulares, debido a la degradación que son capaces de producir. Parte de la discusión se centra en avizorar el sentido y la maldad de dichas actuaciones y la influencia que tienen en nuestra imposibilidad para hablar de un mundo compartido, de una comunidad política, de una filosofía de la proximidad.
Con todo, el mal político pone al hombre en una continua tensión que condiciona sus acciones y lo sume en una entera esclavitud"
