Water trophy assessment of the cooling system of the “Dolna Odra” power plant on the basis of algae indicator organisms
Authors: Kowalski Wojciech , Komarzewska Katarzyna
Published: March 2023

The paper presents the results of water trophy assessment from various stations of the cooling system of the “Dolna Odra” (Poland) power plant. The assessment was made based on the indicator phytoplankton species collected four times at four sites located in different parts of the hydrological system cooling the technical infrastructure of the power plant. The sites were characterised by water with a natural temperature for individual seasons, as well as by thermals changed as a result of the discharge of cooling waters. For each site, the saprobic index was calculated based on indicator species.

The analysis showed that the changes in trophic conditions, both in waters with changed thermals and in waters not subject to the influence of after-cool waters, are not subject to significant changes. The waters of all studied sites in the analysed periods of the year should be classified according to Sladeček and Sládečková (1996) to the waters of the β–mesosaprobic zone, with a saprobic index value ranging from 1.51 to 2.50 (average S = 2.0). This zone is characterised by the course of biochemical processes under aerobic conditions, as a result of which complete oxidation of the intermediate products of decomposition of organic compounds takes place.

Introduction. Recently, much attention has been paid to the problem of new approaches in the treatment of genital herpes in women. The problem is extremely important, because this genital infection is very common in the world. The main types of genital infection are herpes simplex virus (HSV-1) and (HSV-2). Worldwide, more than 400 million people have genital herpes caused by HSV-2. In the United States of America (USA), nearly one in five adults (approximately 40 million people) have HSV-2 infection, with approximately one million new infections occurring each year. The aim of the study. To analyze the modern principles of treatment of genital herpes in women, using literary sources and the results of own research. Materials and methods. In total, twelve publications by foreign authors were selected and processed based on their relevance to the chosen topic, and information on the effectiveness of the use of the antiviral agent “Virostat” in one’s own practice was provided. Results. To date, there are several strategies for the use of antiherpetic drugs (acyclovir, virostat (famciclovir), valacyclovir), which have been studied and tested in cases of first infection with genital herpes, episodic and suppressive cure. There are two important priorities for the treatment of genital herpes: the first is to prevent clinical manifestations and relapses, and the second is to prevent transmission to sexual partners. Our clinical experience allows us to recommend the use of the Ukrainian medicine “Virostat” (producer “Kyiv Vitamin Plant”) for the treatment of HSV infection in women with various clinical manifestations. Conclusions. To date, it should be noted that genital herpes remains a very common sexually transmitted disease. The increasing frequency of HSV-1 and HSV-2 is associated with recurrences of genital ulcer disease. HSV-2 plays a key role in the spread of HIV and, although rare, HSV-1 and HSV-2 lead to severe complications if contracted during pregnancy, both among mothers and newborns. A review of the literature on the treatment of sexually transmitted diseases as of 2021 found few significant advances in the treatment of genital herpes infections. The greater availability of nucleic acid amplification tests for the diagnosis of HSV in the presence of genital ulcers improves diagnosis in the acute phase, but serological tests lack diagnostic accuracy, so advances in the diagnostic algorithm as well as new diagnostic tools are needed. Although the symptoms of genital herpes can be controlled and transmission to sexual partners can be prevented with antiviral therapy, new treatments with new mechanisms of action will improve the well-being of patients. Considering our clinical experience of using the Ukrainian medicine “Virostat” for various clinical manifestations, we recommend its wide implementation and use.

Introduction. More than 15 million cases of AMI are recorded annually in the world, and in Ukraine in 2017 – 41.786 cases. Undoubtedly, acute coronary syndrome (ACS) manifests various complications of blood flow. At the same time, in such patients, significantly fewer works are devoted to predictors of other complications of the cardiovascular system. The aim of the study. Write a literature review and include the results of own research on predictors of predicting cardiovascular events and other complications of the blood flow system in ACS. Materials and methods. We used 49 published articles and our own research results on the study of predictors of predicting cardiovascular events and other complications of the blood flow system after undergoing ACS. The results of our own research are presented in a complex algorithm for predicting SCD in cardiovascular pathology, and our own criteria for cardiovascular events are given. Results. It has been proven that an increase in the thickness of the LV wall in patients with hypertension can be associated with an almost 7-fold increase in the risk of death. In our opinion, LVH in STEMI in combination with hypertension has a negative impact on the development of cardiovascular events. The development of pathological remodeling of the LV leads to further dilatation, deformation of the walls and cavities of the heart, a progressive decrease in the inotropic function of the LV with the development of congestive heart failure. Some authors suggest prognostic predictors of the development of acute left ventricular failure. The prognostic role of endothelial dysfunction in cardiovascular events is poorly understood. Conclusions. In recent years, predictors of the development of cardiovascular events (death, non-fatal MI, stroke, UA), as well as such complications of the blood flow system as acute left ventricular failure, progression of heart failure, development of VE 3-5 grades according to Laun have been established in patients with a transferred STEMI and UA in recent years , severe heart blocks with the occurrence of syncopal states. According to our data, clinical, ECG, and echocardiographic diagnostic criteria are predictors of cardiovascular events. The specified predictors of cardiovascular events and various complications of the blood flow system after a STEMI and UA need to be taken into account by cardiologists, emergency physicians, and family physicians in their practice and to carry out therapeutic measures aimed at preventing their occurrence in patients.
Peer Review of Development Potential of Socially Oriented Non-Profit Organizations in Kuzbass
Authors: Urban O. A. , Demchuk N. V.
Published: March 2023

Social development of single-industry towns of Kuzbass largely depends on the activities of socially oriented non-profit organizations (NGOs). Today, the issues of integrated assessment of NGOs resources and identification of institutional barriers to development seems rather relevant. The article studies these aspects using activity-structural approach based on peer review results (N = 46). The subject of peer review is represented by resources that form the potential of organization’s development in achieving institutional purposes. The interviews of the experts – the heads of non-profit sociallyoriented public organizations from seven municipalities of Kuzbass – were analyzed through the use of interpretive method. As a result, it has been revealed that being financially and materially unsecured and, at the same time, suffering from shortage of professional managers with motivation for public good and the market, the majority of NGOs don’t have significant potential for social development of singleindustry towns in Kuzbass region. Thus, financial, material, personnel, and communication resources are insufficient to ensure high-quality social services to various categories of the population. Interaction with local authorities, businesses, and non-profit organizations has not been institutionalized in the system of social partnership. Institutional obstacles that have a negative impact on the development of the non-profit sector have been identified. The result of the expert survey was specification of urgent support areas for non-profit organizations as well as the development of practical solutions for effective implementation of support measures at municipal levels.
The possibilities of using retinol palmitate in the systemic treatment of generalized hereditary keratinization disorders
Authors: Petrova Stanislava Yu. , Albanova Vera I.
Published: March 2023

Hereditary ichthyosis is a group of generalized hereditary keratinization disorders characterized by general dryness of the skin, peeling, hyperkeratosis and often erythroderma. These manifestations are caused by mutations in genes mainly involved in the formation of the skin barrier. Hereditary ichthyosis is divided into syndromic and non-syndromic. Nonsyndromic ichthyoses include: vulgar ichthyosis, recessive X-linked ichthyosis, autosomal recessive congenital ichthyosis, keratinopathic ichthyosis and other forms. At present, the best result for achieving clinical remission has been established with oral retinoids: retinol palmitate, isotretinoin (1st generation of retinoids) and acitretin (2nd generation of retinoids). The ability of retinol palmitate to regulate keratinization processes, strengthen the epidermal barrier and have an antioxidant effect is used in the treatment of generalized hereditary keratinization disorders. Medium and high therapeutic doses (200010 000 IU/kg/day) are used in the treatment. The prescribed dose of retinol palmitate differs in various nosological forms of ichthyosis, and depends on the severity of the pathological process, the age and weight of the patient, which must be taken into account when prescribing therapy to obtain the best result. It should be noted that clinical manifestations mainly regress at doses that do not lead to the appearance of signs of toxicity of the drug. The methods of retinol palmitate treatment of ichthyosis and ichthyosiform erythroderma are described.

Published: March 2023

The communication within particle agglomerates in industrial alloys can have significant impact on the macroscopic reactivity, putting a high demand on the adaptation of wide-field methodologies to clarify this phenomenon. In this work, we report the application of correlated optical microscopies probing operando both local pH and local surface chemical transformation correlated with identical location scanning electron microscopy to quantify in-situ the structure-reactivity of particle agglomerates of foreign elements in Al alloy. The optical operando analyses allow (i) to reveal and quantify the local production of OH- from proton and oxygen reduction at individual Si- or Fe-rich microparticles and (ii) to quantify (and model) the chemical communication between these active sites, within a few µm range, on the local chemical transformation of the material. Wide-field image analysis highlights the statistical importance of the chemical communication that may introduce a new conceptual framework for the understanding the mechanisms in related fields of charge transfer, electrocatalysis and corrosion.

Published: March 2023

Modified antibodies play essential roles in various fields, such as analysis, diagnosis, and therapy, which require modified antibodies with optimal physical and biological properties. To this aim, the development of methods for site-selective antibody modification is crucial. Herein, we introduce a Fab region–selective antibody modification method using epitope-based affinity labeling. Although affinity labeling exploiting the high affinity between an antibody and its epitope may sound straightforward, it remains as a challenge probably due to target affinity loss caused by modification around the epitope binding site. By thoroughly screening of the modifying agent structure, reaction conditions, and purification methods, we achieved to develop an efficient method for the selective modification of the Fab region of the antibody while maintaining its high affinity for the epitope.

Published: March 2023

Hybrid materials based on metallosilicates are extensively studied for their enhanced catalytic performance. Introducing organic groups into metal silicate catalysts and thus supposedly change the surface hydrophilicity and hydrophobicity has been shown to have an appreciable effect on the catalyst performance in various reactions, including epoxide ring opening reactions and alcohol dehydration. However, the sole organic groups introduction does not unambiguously guarantee hydrophilicity control and might lead to porosity drop, acidity modulation, structural changes, etc. Therefore, a thorough and complex characterization is necessary to provide a complete view of the interaction between the catalyst surface, reactants, and products. Herein, we have prepared aluminosilicate catalyst with well-dispersed Al atoms in silica-based matrices via the non-hydrolytic sol-gel (NHSG) method. This material was post-synthetically modified with trimethylsilyl groups; their number on the catalyst surface was controlled via a temperature vacuum pretreatment. In such a way, we have obtained aluminosilicate materials with similar porosity, structure, and acid site strength and quality. Notably, the water sorption measurements showed that trimethylsilylated aluminosilicates adsorb 2.5−3 times less water (p/p0 = 0.3) than the parent aluminosilicate catalyst. The turn over frequency in epoxide ring opening and ethanol dehydration scaled up with the number of trimethylsilyl groups grafted on the catalyst surface. Particularly, the heavily trimethylsilylated sample achieved three to five times higher turnover frequency in styrene oxide aminolysis with aniline than the parent aluminosilicate material. To the best of our knowledge, it exhibited the most active Al sites for epoxide aminolysis in the present literature.

Published: March 2023

While perovskite light-emitting diodes (PeLEDs) have demonstrated external quantum efficiencies (EQEs) well over 20%, their stability limits their commercial viability. Previously, the incorporation of transition metal dopants has demonstrated improved PeLED brightness, stability, and efficiency. Here, we dope Mn2+ ions into a quasi-bulk 3D perovskite and introduce tris(4-fluorophenyl)phosphine oxide (TFPPO) to achieve a 14.0% peak EQE and 128,000 cd/m2 peak luminance. However, while the incorporation of TFPPO dramatically increases PeLED EQE, their stability is severely compromised. At a 5 mA/cm2 electrical current bias, PeLEDs fabricated without TFPPO (2.97% EQE) and with TFPPO (14.0% EQE) decay to half their maximum luminance in 37.0 and 2.54 minutes, respectively. In order to investigate this trade-off in EQE and stability, we study both photophysical and optoelectronic characteristics before and after PeLED electrical operation. While Mn2+ doped PeLEDs hold the potential to enable bright and efficient lighting, device stability degradation mechanisms must be further investigated.

BASE NACIONAL COMUM CURRICULAR: DISPUTAS NA PRODUÇÃO DE CONHECIMENTO
Authors: Brandt Andressa Graziele , Lima Edilene Eva de
Published: March 2023

o movimento de discussão iniciado em 2013 no Brasil, promovido pelo Ministério da Educação (MEC) em prol da elaboração de uma Base Nacional Comum Curricular (BNCC), vem causando um certo desconforto para o campo educacional brasileiro, apresentando-se como uma política curricular que impõe um currículo mínimo, e não uma Base Nacional curricular com forte embasamento teórico. No presente texto, procuramos apresentar uma breve contextualização de como a Base Nacional vem se constituindo, assim como, a partir do nosso ponto de vista, analisar como BNCC está se materializando em política curricular e na produção de conhecimento nas instituições educacionais. Para tanto, as reflexões terão embasamento nos enfoques e nas abordagens observadas na obra das autoras Macedo (2006), Lopes e Macedo (2011), Frigotto (2011), Shiroma e Evangelista (2011), Montaño e Duriguetto (2013), que trazem contribuições significativas para o campo da política curricular.
COMUNICAÇÃO FAMÍLIA E ESCOLA: TENSÕES E DESAFIOS
Authors: Glidden Rosina Forteski
Published: March 2023

O debate em torno dos encontros e desencontros na relação família e escola tem merecido uma atenção especial, pois urge que a escola seja, também para os pais e responsáveis, um espaço agradável, no do qual estes atores sintam-se inclinados a exercer uma participação ativa e desenvolvam um sentimento de pertença e corresponsabilização. Diante desta questão, o presente estudo objetivou apresentar as tensões e os desafios que permeiam a comunicação família e escola apontados na literatura científica. Para tanto foi feita uma revisão seletiva não sistemática de artigos nacionais e internacionais. Conclui-se pela existência de agruras na comunicação família e escola, sendo que os fatores de risco predominam nos resultados, em detrimento dos fatores de proteção. Parece haver uma posição defensiva e territorial da escola que fragmenta e isola este espaço, privando-o das férteis contribuições que resultam de uma articulação menos verticalizada com a família e a comunidade.
A QUEM CABE A PROTEÇÃO DO VULNERÁVEL? AS CONTRIBUIÇÕES DOS MOVIMENTOS SOCIAIS DA DÉCADA DE 1990 NA LUTA PELA GARANTIA DOS DIREITOS DE CRIANÇAS E ADOLESCENTES
Authors: Santos Émina Márcia Nery dos , Ferreira Andréa Márcia Monteiro
Published: March 2023

o texto objetiva analisar as contribuições dos movimentos sociais na década de 1990 para a instituição dos direitos das crianças e dos adolescentes no Brasil, em especial, no que diz respeito ao Estatuto da Criança e do Adolescente (ECA). O estudo resulta de revisão bibliográfica, acompanhada da análise de conteúdo, a partir de entrevista realizada com o Padre Bruno Sechi, na qual se evidenciou que as políticas públicas de atendimento na área da infância e da adolescência evoluíram consideravelmente a partir do ECA, mas, ainda são desafios para o poder público e a sociedade civil. Considera que esses direitos podem ser consolidados com a criação de uma rede de proteção social que articule ações entre diferentes campos, efetivando o atendimento das crianças e dos adolescentes no que diz respeito aos direitos inerentes à existência humana.

A pesquisa fez uso de procedimentos metodológicos quantitativos, como a consulta a um banco de dados da própria Universidade, além de fontes documentais. Os resultados apresentaram que, até o primeiro período de 2015, as licenciaturas tiveram um índice de evasão superior a 48%, chegando, em alguns casos, a 80%. Embora exista uma grande necessidade de docentes para atuarem em sala de aula, são poucos os estudantes que concluem o seu curso.
Sınıf Öğretmenlerinin Perspektifinden Akran Zorbalığı ve Göçmen/Mülteci Çocuklar
Authors: KARATAŞTAN Ayşe , AKCAN Emrullah
Published: March 2023

Okul ortamları sosyal, davranışsal ve kültürel anlamda pek çok faktörden etkilenmektedir. Bu faktörlerden biri de akran ilişkileridir. Çocukların akranları ile sağlıklı iletişim kurma konusunda başarılı olması sosyalleşme ve yaşamlarının sonraki süreçlerinde topluma uyum sağlaması açısından önemli unsurlardandır. Okul içerisinde akran zorbalığına sebep olan saldırganlık ve şiddet yalnızca zorba ve mağdur öğrencileri değil aynı zamanda okula devam eden diğer öğrencileri de fiziksel, sosyal ve ruhsal açıdan olumsuz etkilemektedir. Bu araştırmanın amacı sınıf öğretmenlerinin görüşleri doğrultusunda göçmen/mülteci öğrencileri ve akran zorbalığını incelemektir. Çalışmanın katılımcı grubu, 2020-2021 eğitim öğretim yılında Gaziantep ili Şahinbey ilçesindeki dört okulda görev yapmakta olan 8 sınıf öğretmeninden oluşmaktadır. Nitel araştırma yönteminin kullanıldığı bu çalışma, durum çalışması deseni kapsamında yürütülmüştür. Yapılan araştırmada verilerin toplanması amacıyla yarı yapılandırılmış görüşme formu kullanılmıştır. Elde edilen veriler, içerik analizi yoluyla çözümlenmiştir. Araştırmada göçmen/mülteci öğrencilerin Türk akranları tarafından çeşitli zorbalıklara uğradıkları sonucuna ulaşılmıştır. Göçmen/mülteci öğrencilerin uğradıkları akran zorbalıklarının nedenlerinin dilden kaynaklanan iletişim yetersizliği, Türk ailelerin ön yargılı tutumlarının çocuklarını etkilemesi ve göçmen/mülteci öğrencilerin uyum sağlayamamasından kaynaklandığı bulgusuna ulaşılmıştır. Öğretmenlerin akran zorbalıklarını azaltmaya yönelik önerileri incelendiğinde, ailelerin bilinçlendirilmesi ile Türk öğrencilerin okula önyargısız gelmesinin sağlanabileceği, sonrasında gerek aileler gerekse öğrenciler için birbirini tanımaya fırsat verecek sosyalleşme etkinliklerinin olması gerektiği, öğrenciler için ise paylaşım olanağının yoğun olduğu grup çalışmaları ve empati çalışmalarının Türk ve göçmen/mülteci öğrenciler arasındaki zorbalık vakalarını azaltabileceği sonucuna ulaşılmıştır.

Bu çalışmada, sağlık yönetimi bölümü öğrencilerinin Covid-19 ile ilgili bilişsel yapılarının incelenmesi amaçlanmaktadır. Fenomenoloji desenine göre tasarlanan çalışmada veri toplamak amacıyla kelime ilişkilendirme testi kullanılmıştır. Testte anahtar kavram olarak Covid-19 belirlenmiş ve Covid-19’un neyi çağrıştırdığı, neye benzetildiği, olumsuz etkileri, olumlu etkileri ve geleceği nasıl şekillendireceği üzerinden öğrencilerin bilişsel yapıları ortaya konmuştur. Ulaşılan 80 öğrenciden her bir kategoriye ait 800 olmak üzere toplamda 4000 kelimelik bir veri seti elde edilmiş, veriler içerik analizine tabi tutularak temalaştırılmıştır. Analiz sonucunda çağrışım olarak “maske” ve “mesafe”, benzetme olarak “grip” ve “veba”, olumsuz etki olarak “eğitimde yaşanan aksaklıklar” ve “psikolojinin bozulması”, olumlu etki olarak “aile ile vakit geçirme” ve “kendine vakit ayırma”, gelecek etkisi olarak ise “tedbirli yaşam” ve “ekonomik problemlerde artış” kodları öne çıkmıştır. Sonuç olarak, Covid-19 denilince üniversite öğrencilerinin aklına daha çok tedbir ve korunmaya dair çağrışımlar gelmiş, öğrenciler Covid-19’u bulaşıcı ya da ölümcül hastalıklara benzetmiş, olumsuz etkilerin başında kısıtlama ve tedbirler düşünülmüş, olumlu etkiler olarak süreç gelişim ve öğrenme fırsatı olarak görülmüş ve gelecekte bu salgın sebebiyle toplumsal yaşamın dönüşeceğine dair düşünceler ortaya çıkmıştır.
ANALYZING THE FINANCIAL PERFORMANCE OF AUTOMOTIVE COMPANIES BEFORE AND AFTER INDUSTRY 4.0: AN APPLICATION IN THE BIST SUSTAINABILITY INDEX
Authors: CEYHAN İsmail Fatih , KARA Merve
Published: March 2023

Today, the "Industry 4.0 revolution", which offers opportunities such as a substantial competitive advantage, increase in production capacity, and cost reduction, is preparing to move institutions to a rapidly changing information age. Therefore, the importance of keeping up with innovations and providing sustainable performance is increasing for businesses in this age. On the other hand, it draws the attention of researchers to whether there is a difference between the financial performances of companies before-after industry 4.0. The study compares the financial performances of automotive companies that have adopted Industry 4.0 methods in the BIST Sustainability Index, before and after Industry 4.0. For this purpose, the companies' financial performances were analyzed and compared between 2013-2015 and 2016-2018 with the Gray Relational Analysis method, one of the multi-criteria decision-making techniques. The entropy which is an objective method, was preferred for weighting the criteria. Ten financial ratios were used as criteria in the performance evaluation. As a result, almost all companies increase their financial performance, but a decrease occurs only in one company's financial performance with the transition to Industry 4.0. So it can be stated that the increase in the share of R&D expenditures and Industry 4.0 investments will positively affect the financial performance of companies.

Günümüzde bireylerin markalara karşı olan algılarını şekillendiren birçok unsur bulunmaktadır. Ayrıca bu algılar, bireylerin birçok konudaki tutum ve davranışlarını da etkilemektedir. Özellikle sosyal medyanın etki alanını artırması bireylerin markalar ile olan etkileşimlerine yeni bir boyut getirdiği gibi, aralarındaki ilişkiyi şekillendiren faktörleri de etkilemiştir. Mevcut çalışmada sosyal ağlar üzerinden yürütülen pazarlama çalışmalarına ilişkin algıların bireylerin çevrimiçi fikir arama ve iletme davranışlarına nasıl etki ettiği gözlemlenmeye çalışılmıştır. Ayrıca bu algılar üzerinde etkisi olabilecek marka hayranlığı, cinsiyet, çevrimiçi ürün satın alma ve çevrim içi kalma süreleri gibi değişkenlerinde etkileri tartışılmak istenmiştir. Bu noktadan hareketle nicel araştırma yöntemine başvurulup bu yöntemin veri toplama tekniklerinden olan ve birincil verilere ulaşmak amacıyla anket tekniğinden yararlanılmıştır. Elde edilen verilerin analizinde, fark testleri (t-testi, One Way Anova) ve ilişki testleri yapılmıştır. Çalışma kapsamında yapılan araştırma ile özellikle bu algının önemli ölçüde çevrimiçi görüş arama ve iletme davranışları ile bağlantılı olduğu gözlemlenmiştir. Ayrıca çevrimiçi kalma süresi, ürün satın alma sıklığı, marka hayranlığının ve kullanıcıların cinsiyetlerinin de bu algı ile ilişkili olduğu tespit edilmiştir.

The purpose of this study was to determine third party logistics company selection and evaluation criteria and to help make the most suitable selection among the alternatives in the food sector. Another purpose was to present a mixed model by integrating fuzzy multi criteria decision making methods in third-party logistics company selection process. The combination of fuzzy DEMATEL, fuzzy ANP and fuzzy TOPSIS methods were used in this study. A decision network was created by evaluating the interactions between the criteria determined depending on the decision goal. This study was conducted in a large scale company producing milk and dairy products in food sector. As a result of the analyses made and the findings obtained, technology, delivery performance and quality were found as the criteria having the highest scores in terms of effectiveness. In addition, it was also determined that the most affected criterion among the criteria was the company image. The S2 Company was selected as the best third-party logistics company as a result of the evaluation of alternatives. The integrated fuzzy methods used in this study were used for the first time in the selection and evaluation of third-party logistics companies. And three new criteria; namely, portage price, hygiene and vehicle were added to the related literature which did not exist before.

Published: March 2023

En este artículo, estudiamos numéricamente los modos ópticos localizados en un sistema de percolación desordenado 3-D, donde el clúster de percolación inicial es llenado por un medio activo compuesto por emisores de luz incoherente. Se evalúa y estudia la distribución del campo electromagnético y varios aspectos relacionados con la solución de las Ecuaciones de Maxwell, para establecer las condiciones de localización óptica 3-D en el modelo considerado. Investigamos las propiedades de la relación de participación inversa del campo electromagnético; como un parámetro que mide la localización óptica, así como el camino libre medio de los fotones que conecta a los emisores de luz en los poros aleatorios del sistema de percolación.

Published: March 2023

La solución eficiente del problema del camino más corto tiene aplicaciones en áreas tan importantes y actuales como la robótica, las telecomunicaciones, la investigación de operaciones, la teoría de juegos, las redes de computadoras, internet, diseño industrial, fenómenos de transporte, diseño de circuitos electrónicos y otros, por lo que es un tema de gran interés en el área de optimización combinatoria. En el presente trabajo se describe una Red Neuronal Artificial Pulsante capaz de atacar eficientemente el problema del camino más corto entre dos nodos. Una vez que la Red Pulsante encuentra el nodo meta a costo mínimo, se realiza una extracción o Explicitación de Conocimiento de esta Red para recuperar la trayectoria final. Debido al diseño en paralelo de la Red Neuronal aquí presentada, este enfoque de solución puede resultar altamente competitivo, según se observó en la etapa de experimentación a partir de los buenos resultados obtenidos, aún en casos con miles de nodos.

Published: March 2023

Introducción y objetivos: La información sobre la biodiversidad de áreas protegidas es fundamental para desarrollar estrategias de manejo y conservación. En este trabajo evaluamos el número de registros de plantas y vertebrados de Parques Nacionales (PN) de Argentina en función de la riqueza de especies de la provincia donde se encuentra cada PN, analizamos posibles variables explicativas del número de registros en cada PN, y describimos la vegetación registrada en tres PN icónicos del país.
M&M: Los registros de plantas vasculares y de vertebrados, las características de cada PN y la riqueza de especies de la provincia donde se encuentra cada PN se obtuvieron de bases de datos de acceso abierto. Para los PN Calilegua, Iguazú y Nahuel Huapi describimos el número de plantas según familia, origen, endemismo, forma de vida, estado de conservación según UICN e invasividad de especies no nativas.
Resultados: Los PN presentan gran variabilidad en sus registros. Existen pocos registros de especies no nativas. Los PN más antiguos registraron más plantas no nativas. La lista de plantas del PN Nahuel Huapi mostró un mayor número de registro que Calilegua e Iguazú. El número de plantas categorizadas por UICN es muy bajo. Casi todas las plantas no nativas registradas son invasoras en otros lugares del mundo.
Conclusiones: Destacamos la importancia de incrementar el relevamiento de especies en todos los PN, particularmente de plantas y en PN de reciente creación. Se requiere mayor atención a especies no nativas a fin evitar problemas socio-ecológicos asociados a invasiones biológicas.

Published: March 2023

Introducción y objetivos: El cambio climático, el ganado y el creciente uso turístico favorecen la dispersión de plantas exóticas, amenazando la conservación de los ecosistemas altoandinos. Estudiamos los patrones de distribución de plantas nativas y exóticas en senderos recreativos de montaña. M&M: Implementamos el protocolo MIREN en seis senderos (2400-3600 m s.n.m.) en dos áreas protegidas de los Andes centrales de Mendoza en las Cordilleras Frontal y Principal. Resultados: Encontramos 180 especies nativas y 41 exóticas. La riqueza de especies nativas fue máxima a elevaciones intermedias, mientras que la riqueza de exóticas disminuyó con la elevación. La riqueza regional de nativas fue mayor en la Cordillera Frontal que en la Principal (114 versus 71 nativas, respectivamente) mientras que la riqueza regional de exóticas fue menor en la Frontal que en la Principal (20 versus 28 exóticas, respectivamente). La riqueza de exóticas por parcela fue mayor en la Cordillera Frontal que en la Principal. El rango de distribución altitudinal de exóticas fue mayor en la Cordillera Frontal. Dos exóticas abundantes, Taraxacum officinale y Cerastium arvense, estuvieron a lo largo de todo el gradiente en la Cordillera Frontal, alcanzando los 3600 m s.n.m. Encontramos siete exóticas no citadas anteriormente. Conclusiones: Los nuevos registros amplían los rangos de distribución conocidos para algunas especies exóticas. A pesar de que el número de especies exóticas fue similar cerca y lejos de los senderos, cinco especies sólo estuvieron en los bordes de los mismos, lo que sugiere que los senderos favorecen los procesos de invasión.
