Physical and Mechanical Properties of Thermoplastic Composites Filled with Wood Flour of Underutilized Chaste Tree
Authors: Ayrilmis Nadir , Yildiz Esra
Published: November 2022

The potential use of a lignocellulosic filler, Vitex agnus-castus plant (Chaste tree), which is a deciduous invasive shrub, in thermoplastic composites was investigated. The stems of chaste trees with a diameter of 5-10 cm from Mugla city, Western Turkey, were used for the study. The different amounts (0 to 50 wt%, by 10 % increments) of the wood flour passing through the screen openings of 0.237 mm were added to the polypropylene matrix. Premixed raw materials were put into the volumetric feeder of the twin-screw extruder. The extruder barrel temperature was gradually increased from 170 °C (feeding zone) to the die zone (190 °C) at a constant screw speed (40 rpm). Then, the dried granules were hot-pressed into the 4 mm thick WPC panels at 2 MPa and 190 °C for 5 min. 3 wt% of maleic anhydride grafted polypropylene (MAPP) was added as compatibilizer into the formulation. The WPCs showed an increase in the thickness swelling (0.58 to 5.68 %) as the amount of the filler increased from 10 to 50 wt% in the polypropylene. The bending strength of the polypropylene composites increased from 33.9 to 44.8 MPa as the amount of the chaste wood flour was increased to 30 wt%, but further increase caused the decrease in the tensile strength (25.7 MPa). As for the bending modulus, it increased from 815 to 3250 MPa when the wood content reached 50 wt%. The tensile modulus increased from 1690 to 2253 MPa when the wood content arised from 10 to 50 wt%. The tensile strength, tensile modulus, flexural strength and flexural modulus of the unfilled polypropylene were found to be 19.6 MPa, 1505 MPa, 30.2 MPa and 664 MPa, respectively. According to the test results, it was concluded that the 30-40 wt% of Vitex agnus-castus wood could be efficiently used in the polypropylene composites for the semi-building applications such as decking or siding. The evaluation of underused invasive chaste wood in the production of tWPC production may result in an effective way to utilize this resource.

Authors: Prasad Sai , Kondal Rao S. , Anusha M.
Published: November 2022

Since their beginnings, automotive wheels have evolved over decades. Wood and stone were used to make the antique wheel rims. The wheel rim, as an essential and crucial portion of the vehicle, was concentrated on with excessive effort as research and development blossomed throughout the industrial revolution. The study is primarily concerned with improving and optimizing the mass of a car's wheel rim. The primary goal is to reduce the weight of the wheel in order to improve the vehicle's overall performance and economy. Cast iron is the material assigned to the basic model. Following design optimization, the rim is subjected to material optimization, which involves assigning several competitive materials to the optimized design and analyzing and observing them under the identical boundary circumstances. Solid Works is used to solid model the underlying model and redesign it. Solid works software is used to do simulations for static analysis and topology optimization.

A Bayesian Spatial Mixture Model for FMRI Analysis
Authors: Geliazkova Maya
Published: November 2022

We develop, implement and study a new Bayesian spatial mixture model (BSMM). The proposed BSMM allows for spatial structure in the binary activation indicators through a latent thresholded Gaussian Markov random field. We develop a Gibbs (MCMC) sampler to perform posterior inference on the model parameters, which then allows us to assess the posterior probabilities of activation for each voxel. One purpose of this article is to compare the HJ model and the BSMM in terms of receiver operating characteristics (ROC) curves. Also we consider the accuracy of the spatial mixture model and the BSMM for estimation of the size of the activation region in terms of bias, variance and mean squared error. We perform a simulation study to examine the aforementioned characteristics under a variety of configurations of spatial mixture model and BSMM both as the size of the region changes and as the magnitude of activation changes.

On the Mathematical Modelling of Microbial Growth: Some Computational Aspects
Authors: Markov Svetoslav M.
Published: November 2022

We propose a new approach to the mathematical modelling of microbial growth. Our approach differs from familiar Monod type models by considering two phases in the physiological states of the microorganisms and makes use of basic relations from enzyme kinetics. Such an approach may be useful in the modelling and control of biotechnological processes, where microorganisms are used for various biodegradation purposes and are often put under extreme inhibitory conditions. Some computational experiments are performed in support of our modelling approach.
A Method for Classification of Doubly Resolvable Designs and Its Application
Authors: Zhelezova Stela
Published: November 2022

The resolvability of combinatorial designs is intensively investigated because of its applications. This research focuses on resolvable designs with an additional property - they have resolutions which are mutually orthogonal. Such designs are called doubly resolvable. Their specific properties can be used in statistical and cryptographic applications.Therefore the classification of doubly resolvable designs and their sets of mutually orthogonal resolutions might be very important. We develop a method for classification of doubly resolvable designs. Using this method and extending it with some theoretical restrictions we succeed in obtaining a classification of doubly resolvable designs with small parameters. Also we classify 1-parallelisms and 2-parallelisms of PG(5,2) with automorphisms of order 31 and find the first known transitive 2-parallelisms among them. The content of the paper comprises the essentials of the author’s Ph.D. thesis.
A Super-Dimension Approach in ROLAP Environments
Authors: Naydenova Ina
Published: November 2022

Often the designer of ROLAP applications follows up with the question “can I create a little joiner table with just the two dimension keys and then connect that table to the fact table?” In a classic dimensional model there are two options - (a) both dimensions are modeled independently or (b) two dimensions are combined into a super-dimension with a single key. The second approach is not widely used in ROLAP environments but it is an important sparsity handling method in MOLAP systems. In ROLAP this design technique can also bring storage and performance benefits, although the model becomes more complicated. The dependency between dimensions is a key factor that the designers have to consider when choosing between the two options. In this paper we present the results of our storage and performance experiments over a real life data cubes in reference to these design approaches. Some conclusions are drawn.
Integer Programming Approach to HP Folding
Authors: Yanev Nicola , Milanov Peter , Mirchev Ivan
Published: November 2022

One of the most widely studied protein structure prediction models is the hydrophobic-hydrophilic (HP) model, which explains the hydrophobic interaction and tries to maximize the number of contacts among hydrophobic amino-acids. In order to find a lower bound for the number of contacts, a number of heuristics have been proposed, but finding the optimal solution is still a challenge. In this research, we focus on creating a new integer programming model which is capable to provide tractable input for mixed-integer programming solvers, is general enough and allows relaxation with provable good upper bounds. Computational experiments using benchmark problems show that our formulation achieves these goals.
Designing an E-Mail Prototype to Enhance Effective Communication and Task Management: A Case Study
Authors: Katz Adi , Berman Irit
Published: November 2022

This paper deals with communicational breakdowns and misunderstandings in computer mediated communication (CMC) and ways to recover from them or to prevent them. The paper describes a case study of CMC conducted in a company named Artigiani. We observed communication and conducted content analysis of e-mail messages, focusing on message exchanges between customer service representatives (CSRs) and their contacts. In addition to task management difficulties, we identified communication breakdowns that result from differences between perspectives, and from the lack of contextual information, mainly technical background and professional jargon at the customers’ side. We examined possible ways to enhance CMC and accordingly designed a prototype for an e-mail user interface that emphasizes a communicational strategy called contextualization as a central component for obtaining effective communication and for supporting effective management and control of organizational activities, especially handling orders, price quoting, and monitoring the supply and installation of products.

The motivations and results from the first 1.5-year period of the project “Wide-field Plate Database (WFPDB): Development and Access via Internet” (DO-02-273/18.12.2008), approved for funding through a competition held by the Bulgarian National Science Fund in the field of Promotion of Research in Priority Areas, are described. The main direction of the development of the project is digitization and preservation of, and web access to, the astronomical plate archives of the 2-m RCC and the 50/70 cm Schmidt telescopes of the Rozhen National Astronomical Observatory received in the period 1979–1998. The basis of the work is set out in Tsvetkov (2006) [1] and Tsvetkova & Tsvetkov (2006) [2], motivating the project over the past 10 years. The WFPDB (www.wfpdb.org) represents a unique virtual instrument in astronomical research, which allows obtaining information on existing astronomical observations of celestial objects over the past 130 years with the professional astronomical telescopes at observatories around the world. Briefly, this is a unique virtual telescope working as a “Time Machine” for obtaining information on historical observations of minor planets, comets, stars and galaxies. The project also aims to continue and expand the successful work initiated during the past 15 years by extending the provision of technical work on the base, and improving and extending the internal LAN (www.skyarchive.org), which ensures rapid online access to data, based on international standards of the International Virtual Observatory Alliance (IVOA) and the European Virtual Observatory (EURO-VO).

Published: November 2022

The digital preservation of the Konkoly Observatory Schmidt telescope plates, as well as the web access to the plate previews, aim for the preservation of this scientific heritage and the re-use of the astronomical photographic plates in time domain astronomy. The photographic plates used as detectors and information storage at astronomical observations with the Konkoly Schmidt telescope had been obtained in the period 1962–1996. The work on the digital plate preservation and web access started in 2001 with creation of an electronic plate catalogue and the digitization of selected representative plates as well as with interlinking of the publishing in Konkoly Observatory Information Bulletin on Variable Stars (IBVS) with the Wide-Field Plate Database (WFPDB) developing in Sofia. We describe the process of the digitization of the Konkoly Schmidt telescope plates.
Ergodic Rates of the Fast Rayleigh Fading Relay Channel for Different Cooperative Strategies
Authors: Rizinski Maryan , Kafedziski Venceslav
Published: November 2022

This paper investigates the ergodic rates of three cooperative strategies for the fast Rayleigh fading relay channel, namely, decode-and forward (DF), compress-and-forward (CF) and amplify-and-forward (AF). The transmitter-relay, relay-receiver and transmitter-receiver links experience independent fast Rayleigh fading. Our analysis considers both fullduplex and half-duplex modes of operation of the relay channel, assuming that perfect transmit channel distribution information (CDI) is available at the transmitter and the relay. The ergodic rates are compared under different channel conditions to the corresponding upper capacity bounds of the relay channel and to the rate of direct transmission in order to investigate when it is beneficial to use a certain cooperative strategy. Cooperative transmission makes the ergodic rates approach or even become identical to theupper capacity bounds if some conditions are satisfied. The results show that DF and CF outperform AF as they are more complex strategies, while AF itself achieves higher rates than direct transmission in most channel scenarios, thus trading performance for implementation simplicity.ACM Computing Classification System (1998): E.4, C.2.1.

Classifier PGN: Classification with High Confidence Rules
Authors: Mitov Iliya , Depaire Benoit , Ivanova Krassimira , Vanhoof Koen
Published: November 2022

Associative classifiers use a set of class association rules, generated from a given training set, to classify new instances. Typically, these techniques set a minimal support to make a first selection of appropriate rules and discriminate subsequently between high and low quality rules by means of a quality measure such as confidence. As a result, the final set of class association rules have a support equal or greater than a predefined threshold, but many of them have confidence levels below 100%. PGN is a novel associative classifier which turns the traditional approach around and uses a confidence level of 100% as a first selection criterion, prior to maximizing the support. This article introduces PGN and evaluates the strength and limitations of PGN empirically. The results are promising and show that PGN is competitive with other well-known classifiers.ACM Computing Classification System (1998): H.2.8, H.3.3.

This paper examines the image processing and pattern recognition techniques that can be adopted for automatic extraction of astronomical data from stars’ triple expositions that can aid variable stars detection in Carte du Ciel maps.
JSONYA/FN: Functional Computation in JSON
Authors: Sredkov Miloslav
Published: November 2022

Functional programming has a lot to offer to the developers of global Internet-centric applications, but is often applicable only to a small part of the system or requires major architectural changes. The data model used for functional computation is often simply considered a consequence of the chosen programming style, although inappropriate choice of such model can make integration with imperative parts much harder. In this paper we do the opposite: we start from a data model based on JSON and then derive the functional approach from it. We outline the identified principles and present Jsonya/fn — a low-level functional language that is defined in and operates with the selected data model. We use several Jsonya/fn implementations and the architecture of a recently developed application to show that our approach can improve interoperability and can achieve additional reuse of representations and operations at relatively low cost.

On a Theorem by Van Vleck Regarding Sturm Sequences
Authors: Akritas Alkiviadis , Malaschonok Gennadi , Vigklas Panagiotis
Published: November 2022

In 1900 E. B. Van Vleck proposed a very efficient method tocompute the Sturm sequence of a polynomial p (x) ∈ Z[x] by triangularizingone of Sylvester’s matrices of p (x) and its derivative p′(x). That method works fine only for the case of complete sequences provided no pivots takeplace. In 1917, A. J. Pell and R. L. Gordon pointed out this “weakness” inVan Vleck’s theorem, rectified it but did not extend his method, so that italso works in the cases of: (a) complete Sturm sequences with pivot, and (b)incomplete Sturm sequences.Despite its importance, the Pell-Gordon Theorem for polynomials inQ[x] has been totally forgotten and, to our knowledge, it is referenced byus for the first time in the literature.In this paper we go over Van Vleck’s theorem and method, modify slightlythe formula of the Pell-Gordon Theorem and present a general triangularization method, called the VanVleck-Pell-Gordon method, that correctly computes in Z[x] polynomial Sturm sequences, both complete and incomplete.

A Taxonomy of Big Data for Optimal Predictive Machine Learning and Data Mining
Authors: Fokoué Ernest
Published: November 2022

Big data comes in various ways, types, shapes, forms and sizes.Indeed, almost all areas of science, technology, medicine, public health, economics, business, linguistics and social science are bombarded by ever increasing flows of data begging to be analyzed efficiently and effectively. Inthis paper, we propose a rough idea of a possible taxonomy of big data,along with some of the most commonly used tools for handling each particular category of bigness. The dimensionality p of the input space andthe sample size n are usually the main ingredients in the characterizationof data bigness. The specific statistical machine learning technique used tohandle a particular big data set will depend on which category it falls inwithin the bigness taxonomy. Large p small n data sets for instance require a different set of tools from the large n small p variety. Among othertools, we discuss Preprocessing, Standardization, Imputation, Projection,Regularization, Penalization, Compression, Reduction, Selection, Kernelization, Hybridization, Parallelization, Aggregation, Randomization, Replication, Sequentialization. Indeed, it is important to emphasize right away that the so-called no free lunch theorem applies here, in the sense that there is no universally superior method that outperforms all other methods on all categories of bigness. It is also important to stress the fact that simplicity in the sense of Ockham’s razor non-plurality principle of parsimony tends to reign supreme when it comes to massive data. We conclude with a comparison of the predictive performance of some of the most commonly used methods on a few data sets.
Accent Recognition for Noisy Audio Signals
Authors: Ma Zichen , Fokoué Ernest
Published: November 2022

It is well established that accent recognition can be as accurateas up to 95% when the signals are noise-free, using feature extraction techniques such as mel-frequency cepstral coefficients and binary classifiers such as discriminantanalysis, support vector machine and k-nearest neighbors. In this paper, we demonstrate that the predictive performance can be reduced by as much as 15% when the signals are noisy.Specifically, in this paper we perturb the signals with different levels of white noise, and as the noise become stronger, the out-of-sample predictive performance deterioratesfrom 95% to 80%, although the in-sample prediction gives overly-optimistic results.
Sturm Sequences and Modified Subresultant Polynomial Remainder Sequences
Authors: Akritas Alkiviadis , Malaschonok Gennadi , Vigklas Panagiotis
Published: November 2022

In 1971 using pseudo-divisions - that is, by working in Z[x] - Brown and Traub computed Euclid’s polynomial remainder sequences (prs’s) and (proper) subresultant prs’s using sylvester1, the most widely known form of Sylvester’s matrix, whose determinant defines the resultant of two polynomials. In this paper we use, for the first time in the literature, the Pell-Gordon Theorem of 1917, and sylvester2, a little known form of Sylvester’s matrix of 1853 to initially compute Sturm sequences in Z[x] without pseudodivisions - that is, by working in Q[x]. We then extend our work in Q[x] and, despite the fact that the absolute value of the determinant of sylvester2 equals the absolute value of the resultant, we construct modified subresultant prs’s, which may differ from the proper ones only in sign.

A set of n lattice points in the plane, no three on a line and no four on a circle, such that all pairwise distances and coordinates are integers is called an n-cluster (in R^2). We determine the smallest 7-cluster with respect to its diameter. Additionally we provide a toolbox of algorithms which allowed us to computationally locate over 1000 different 7-clusters, some of them having huge integer edge lengths. Along the way, we have exhaustively determined all Heronian triangles with largest edge length up to 6 · 10^6.

Published: November 2022

Tras la conquista de Constantinopla (1453), los focos de resistencia contra los turcos eran prácticamente residuales en los Balcanes. Tan solo el albanés Gjergj Kastrioti (¿c. 1405?-1468) (Skanderbeg) mantuvo una resistencia notable frente al turco. A lo largo de su vida ayudó a forjar también la identidad nacional albanesa. En este artículo estudiamos y contraponemos la imagen contrapuesta y contradictoria que ofrecieron sobre el líder albanés los cronistas e historiógrafos albaneses, bizantinos y un cronista turco. Tras la lectura de esas fuentes, contextualizadas con la bibliografía secundaria que ha generado Skanderbeg, se concluye que el personaje fue descrito según los intereses apriorísticos de sus autores: desde el elogio a la crítica, y también algunos silencios reveladores.

Published: November 2022

Desde una perspectiva icónico-textual, se plantea una lectura del «episodio de don Melón de la Huerta y de doña Endrina», del Libro de buen amor, a la luz del concepto de trampantojo. Con ello, se atenderá a dos aspectos fundamentales de la literatura medieval y, en particular, de la obra del Arcipreste de Hita: la configuración imagocéntrica y la ambigüedad como voluntad constructiva. Se demostrará cómo el engaño asociado a la experiencia amorosa explica la mutación identitaria del yo poético, que, en un juego de confusa tensión entre materialidad y referencialidad, asumirá un nuevo perfil, de carácter plástico, al punto de erguirse como protagonista de un peculiar bodegón.
THE IMPACT OF MICROFINANCE ON POVERTY REDUCTION THROUGH WOMEN’S EMPOWERMENT
Authors: Jamaluddeen  , Alam Serene
Published: November 2022

This study examines how Microfinance Institutions (MFIs) and micro-credit (MC) facilities has put a positive impact on poverty reduction by empowering the women of the society. Women’s Empowerment has become a central issue for the development of the country. Microfinance (MF) has hence taken an initiative and played a very important role by providing MC and improving the financial condition of these women. In this study, the survey method of data collection has been adapted and we have considered 336 respondents of SHGs out of 400 questionnaires yielding a response rate of about 84% from the people residing in rural areas of the Alipurduar district of West Bengal. After the collection of the data, a reliability test (Cronbach Alpha) has been done followed by correlation (Pearson) and multiple Regression analyses which were used to test the hypothesis. It was observed that the three variable that was taken into consideration (i.e., socioeconomic status, women’s position in the family/society, and financial benefit from SHGs) have a significant positive impact on women’s empowerment through MF. The findings in the study bring up certain valuable contributions to the MFIs for better designing of the policies and strengthening and encouraging their future work to empower women and reduce the level of poverty. If the women are encouraged to join the SHG and MFIs provide financial benefits to them, the objective of equal participation may be achieved.

Autor artykułu wychodzi z podstawowego założenia, że ratyfikacja traktatów międzynarodowych ma dualną postać. Z jednej strony ‒ jest ona aktem prawa międzynarodowego, uregulowanym w przepisach tego prawa i wywołującym skutki międzynarodowe, z drugiej strony ‒ ratyfikacja jest czynnością prawa krajowego państwa będącego stroną traktatu, uregulowaną w prawie wewnętrznym, najczęściej mającym rangę konstytucji. Niemniej artykuł koncentruje się na wewnątrzkrajowych procedurach ratyfikacji, uwzględniając kontekst obowiązującej Konstytucji Rzeczypospolitej Polskiej. W tym celu autor komentuje generalne zakotwiczenie tematyki prawa międzynarodowego w Konstytucji, a następnie przechodzi do różnych trybów ratyfikacji traktatów międzynarodowych. Przedstawiono w związku z tym tzw. ratyfikację prostą (małą), ratyfikację dużą (wymagającą zgody parlamentu wyrażonej w formie ustawy) orz ratyfikację szczególną, związaną z traktatami, przekazującymi część kompetencji na rzecz organizacji międzynarodowych.

Cel: Ocena podejścia osób starszych do wybranego produktu finansowego uzupełniającego krajowy system emerytalny − w tym przypadku odwróconej hipoteki.
Materiały i metody: Badanie przeprowadzono metodą pogłębionego wywiadu grupowego. Przeprowadzono trzy sesje badawcze, w których uczestniczyło odpowiednio 8,10 i ponownie 10 osób.
Wyniki: Seniorzy, choć są świadomi istnienia odwróconej hipoteki, nie mają dostatecznego zaufania do niepublicznych instytucji finansowych, by przekazać im swoje nieruchomości. Ważkim elementem przy podejmowaniu decyzji są uwarunkowania kulturowe (rodzina i relacje z najbliższymi). Obawy budzi również naruszanie stosunków własnościowych w złożonej sytuacji geopolitycznej, (bliskość wojny rosyjsko-ukraińskiej). Wyniki badań wskazują na konieczność przeprowadzenia szerszych badań ilościowych na grupie reprezentatywnej: osób, które już przeszły na emeryturę i mogą odczuwać stopniowy deficyt kapitału.
Síndrome cerebeloso por criptococosis, una presentación atípica de esta enfermedad
Authors: Muñoz-Lombo Jenny Patricia , Ocampo Chaparro José Mauricio , Echeverry Andrés Fernando , Casanova Valderrama María Eugenia , Bravo Padilla Víctor
Published: November 2022

Introducción: El síndrome cerebeloso se caracteriza por presentar vértigo, mareo, ataxia, deficiencias posturales y/o de la marcha. Tiene múltiples etiologías, entre ellas las infecciones, siendo el Cryptococcus uno de los agentes micóticos más frecuentes por su tropismo por el líquido cefalorraquídeo; es extremadamente rara a nivel cerebeloso, especialmente en pacientes inmunocompetentes. Materiales y métodos: Estudio descriptivo, tipo reporte de caso. Se revisó la literatura y se comparó con el caso. Presentación de Caso: Adulta mayor diabética que convive con aves; consulta por clínica con un mes de evolución de síntomas neurológicos, de predominio cerebeloso con deterioro progresivo. Se realiza tomografía axial computarizada cerebral que evidencia cambios evolutivos propios de la edad, pero por su evolución clínica tórpida, se solicitó resonancia magnética cerebral donde se aprecian múltiples lesiones quísticas a nivel cerebeloso en forma de gelatina, hiperintensas en T2. Por ello, se realiza punción lumbar que evidenció alteraciones en el citoquímico, tinta china positiva y cultivo para hongos positivo para Cryptococcus Neoformans. Se inició tratamiento con anfotericina B; sin embargo, la paciente fallece. Discusión: El Cryptococcus neoformans en una levadura que causa frecuentemente infección sistémica en pacientes inmunocomprometidos, pero la inmunosenescencia da al anciano un aumento en la susceptibilidad a este. Los pacientes suelen sufrir cuadros de meningitis o meningoencefalitis, existiendo pocos reportes en la literatura sobre su ubicación a nivel cerebeloso. Para este diagnóstico se hace indispensable la realización de ayudas imagenológicas y de punción lumbar que permitan identificar las características propias de esta infección, a fin de iniciar así un tratamiento adecuado y oportuno. Conclusión: La evolución del Cryptococcus es notoria, lo que justifica una mayor sospecha clínica de este tipo de infecciones, aún en poblaciones inmunocompetentes, ya que un diagnóstico tardío y una terapia médica inadecuada se asocian con una alta mortalidad.
Aniversario no. 146 de la Academia Nacional de Medicina de Colombia

En enero de 1873 fue creada la Sociedad de Medicina y Ciencias Naturales. Esta es la primera institución científica que se crea en Colombia; todos sus fundadores eran médicos de gran prestigio en la ciudad de Bogotá, quienes observaron la necesidad de la creación de esta sociedad para que, de una u otra forma, participaran en la organización de los diferentes aspectos de la Medicina Nacional en ese momento incipiente. Siete años después y en un acto simbólico, solemne y de trascendencia nacional en que participaron, entre otros, representantes del gobierno nacional y médicos, y mediante la Ley 71 de 1890, esta sociedad se transforma en la Academia Nacional de Medicina, organismo que desde sus inicios iría a participar e intervenir grandemente en lo relacionado con la salud en Colombia. Evidentemente y, quizá gracias a la Ley 71 de 1890, no solo hay un reconocimiento para con la Academia naciente, sino un estímulo para con sus fundadores. Se establece desde ese momento un vínculo con el Estado y así se empieza a desarrollar un polo importante de la Medicina Nacional. Puede decirse que los grandes hechos, conceptos importantes, proyección e ideas futuristas y de desarrollo que han sucedido en el país y relacionados con la educación médica, la Medicina y la salud pública en Colombia, en algún momento tuvieron su origen, inicio o conceptualización en la Academia Nacional de Medicina.

Este año hemos designado al Académico Ejemplar. Y ¿quién debe ser el Académico Ejemplar? Muy seguramente, varios entre todos nosotros, los académicos, merecen esta designación. Pero este debe ser un líder académico de grandes características profesionales, científicas, académicas y humanas. Debe ser un académico líder en su pensamiento y sus realizaciones. Un académico de trascendencia, hechos y con interés en lo social. Debe ser un académico de ejecutorias, obras y proyecciones. Debe ser un académico líder de ideales y un gran ser humano. Debe ser un académico de nuestra Academia y que nos haya liderado con su palabra, su ejemplo y su cumplimiento. Debe ser un académico líder, una persona de virtudes que exprese en su pensamiento y en su actuar, prudencia, rectitud, sensatez, buen consejo y transparencia, en fin, un académico líder y virtuoso.

Hoy, esta designación le corresponde a la Académica Beatriz Suárez de Sarmiento, cuya trayectoria se describe a continuación:

Recibió el título de Licenciada en Enfermería en abril de 1968, en la primera promoción de Licenciatura de la Facultad de Enfermería de la Universidad Jav eriana. Su primer trabajo fue en el Hospital Universitario de San Ignacio, donde se desempeñó durante un año en el Programa de Liderazgo en Enfermería, bajo la dirección de Sister Mary Lea. En 1969 ingresa como instructora en la Facultad de Enfermería de la Universidad Javeriana y en el año 1970 inicia estudios de Magister en Enfermería en Salud Mental y Psiquiatría en la Universidad del Valle, con beca de la Fundación Rockefeller y apoyada por la Universidad Javeriana.
La lepra: una enfermedad vigente
Authors: Guerrero Guerrero Martha Inírida
Published: November 2022

Fragmento

Respaldado y patrocinado por el Centro Dermatológico Federico Lleras Acosta, este libro aborda el tema que históricamente ha sido de particular interés para la institución. Sobriamente diseñado y diagramado, es el resultado del aporte juicioso y la dedicación de los veinte autores involucrados, quienes realizaron un trabajo prodigioso en cuanto a la presentación de cada aspecto temático por la relevancia descriptiva y las ilustraciones documentales, así como por su seriedad científica.

Como su título lo indica, el libro resalta que la lepra continúa siendo una enfermedad presente en Colombia y que aún constituye un problema de salud pública importante por los costos sociales, económicos y de sufrimiento humano que conlleva. Sabiendo que la literatura sobre el tema es escasa en nuestro medio, este libro surge como una herramienta de consulta creada para médicos y otros profesionales de salud, con la certeza de que es preciso mejorar la oportunidad del diagnóstico, siendo fundamental que durante su proceso formativo, todos los profesionales de la salud adquieran conocimientos sobre dicha enfermedad, que cada día se hace más visible por sus secuelas y diagnóstico tardío.

Discurso pronunciado en la ceremonia religiosa celebrada en memoria del Doctor José Félix Patiño Restrepo, en la capilla de los santos apóstoles del Gimnasio Moderno en Bogotá. Amigos todos: en esta ceremonia religiosa que se celebra en memoria del doctor José Félix Patiño, quiero presentar ante todo un saludo afectuoso y profundamente doloroso a sus hijas Mariana, María Isabel y María Olga, a su hermana María Cristina, a sus nietos y nietas, y a todos los miembros de su adorable familia. Un afecto que se extiende, además, a la memoria siempre viva de Blanca Osorio, su esposa, de su hija Lucía y de Mercedes, su hermana, que se anticiparon a José Félix en su viaje a la eternidad; y un saludo también muy especial a sus discípulos y amigos que le acompañaron de cerca en la etapa final de su extraordinaria parábola vital. En momentos como este, de abatimiento y de dolor espiritual, surgen en mi memoria recuerdos más amables de otros días que pugnan por salir. Conocí a José Félix cuando aún no habíamos cumplido los 10 años de edad y fui su amigo y, más que amigo, su hermano desde entonces. Recuerdo que jugábamos con bolas coloreadas de cristal, un juego al que extrañamente le dábamos el nombre de “todos ganan, nadie pierde”, una especie de ingenua postura filosófica infantil que ambos habríamos de recordar y aplicar en diversas circunstancias de la vida adulta.

La gran “C”. el legado del Radium

Marie Sklodowska-Curie, fue una mujer extraordinaria, que nació en Varsovia, Polonia, el 7 de noviembre de 1867. Debido a que a las mujeres no se les permitía estudiar en las universidades polacas, abandonó el país para continuar su educación en Francia. Obtuvo su licenciatura en física en la Facultad de Ciencias de la Sorbona en 1893, y en matemáticas un año después. En 1894 le presentaron a Pierre Curie (1859-1906), un físico francés. Poco después, Pierre se dio cuenta de que había encontrado un alma compatible y le escribió a Marie: “Qué maravilloso sería si pudiéramos pasar nuestras vidas juntos, siguiendo nuestras ideas. Tus ideas patrióticas y nuestras ideas comunes de humanidad e investigación”. Su matrimonio (25 de julio de 1895) marcó el comienzo de una relación extraordinaria. Trabajaban en un viejo cobertizo de madera, con techo de claraboya, un antiguo prosectorium de la facultad de medicina. Pierre se concentró en la física, Marie en la química, y se ocupó principalmente en aislar las sales de uranio de toneladas de minerales. Marie publicó su primer trabajo de investigación sobre el magnetismo del acero templado. Presentó los resultados en solitario sobre los rayos de Becquerel y sugirió la existencia de un nuevo elemento. Pierre Curie se unió a su trabajo de investigación en marzo de 1898. La investigación de Curie sobre la radiación en el mineral de uranio condujo, en 1898, al descubrimiento de dos nuevos elementos químicos altamente radiactivos, el polonio (nombrado por Marie en honor a Polonia) y el radio. En 1911 recibió el Premio Nobel de Química por su trabajo sobre el aislamiento del radio metálico. Ese mismo año participó en la Conferencia de Solway, donde fue la única mujer entre científicos que incluían a Niels Bohr, Max Planck y Albert Einstein. Gracias a los esfuerzos de Marie Sklodowska-Curie, en 1912 se fundó el Radium Intitute de París (el sueño de Pierre). En 1914, Marie se convirtió en directora del Pabellón Curie´s y trabajó allí hasta su muerte. El impacto social del trabajo de Marie Curie se puede ver a lo largo del siglo pasado, su compromiso condujo al desarrollo de la energía nuclear y la radioterapia para el tratamiento del cáncer, y también mejoró la imagen de la ciencia.
