Una propuesta de la lógica terminológica: El lenguaje de conceptos
Authors: Lizcano Bueno Luis Ignacio , Ojeda Ch. Luis Roberto
Published: May 2022

El presente artículo describe los lenguajes de conceptos o lógicas descriptivas (DLs: Description Logics) de la familia KLONE. Los lenguajes de conceptos permiten representar el conocimiento de un dominio por medio de conceptos y roles, donde los conceptos modelan clases de individuos y los roles especifican relaciones entre las clases. De la combinación de conceptos atómicos y roles atómicos con adecuados constructores se generan expresiones de conceptos. Los lenguajes de conceptos están dotados de la semántica declarativa al estilo de Tarski, donde los conceptos son interpretados como subconjuntos de un dominio, y los roles como relaciones binarias. La semántica de conceptos identifica los lenguajes de conceptos como fragmentos de la lógica de predicados de primer orden. El razonamiento sobre los conceptos está basado en la relación de subsumisión. Esta relación implícitamente define una taxonomía entre los conceptos.

Alternatives for modifying the Somogyi-Nelson method for determining reducing sugars by using their thermical possibilities
Authors: González Blair Gloria Helena , Castellanos Domínguez Óscar Fernando
Published: May 2022

This article proposes modifying the Somogyi-Nelson method for determining reducing sugars, considering that sodium arsenate (one of its constituents) is a toxic substance which is tending to disappear from the market. The chemical principles used in the Somogyi-Nelson method for determining reducing sugars are explained, taking those protocols proposed by Hawk et al (1954), Collmer et al (1988), Castellanos (1995) and the Universidad Nacional’s Chemistry Department (adapted from Fischer’s protocol [1989]) as reference. The reactions of Somogyi and Nelson’s reagents are evaluated separately. The reaction between the two components and a reducing sugar is analyzed and two alternatives for modifying the method are included: the use of phosphates and that of silicates. It is proposed to substitute sodium arsenate for a in the first case and in the second for a silicate.

Granulometric study of form and size of the particles of black re-granulated of cork residuals and low quality cork, have a great interest because it influences the proportion of resin and necessary cork for the formation of bound black regranulates by means of the use of natural resin/subresin as of different synthetic resins and in their application in projection teams of commercial particles for the formation of uniform films with a more economic cost.
In accordance with the results obtained in this and another works, it is recommended like good values of the particles a half size among (1-2,5 mm), since minimizes the effect it bounces and the quantity of resin so much natural as synthetic what allows a degree of good compacting. Everything it, supposes to improve the industrial applications and to optimize the use of commercial teams of projection of cork particles to obtain uniform movies in surfaces (insulating thermal or acoustic).
Finding protein sites using machine learning methods
Authors: Bobadilla Molina Jaime Leonardo , Niño Fernando , Mojica Tobías
Published: May 2022

The increasing amount of protein three-dimensional (3D) structures determined by X-ray and NMR technologies as well as structures predicted by computational methods results in the need for automated methods to provide initial annotations. We have developed a new method for recognizing sites in three-dimensional protein structures. Our method is based on a previously reported algorithm for creating descriptions of protein microenvironments using physical and chemical properties at multiple levels of detail. The recognition method takes three inputs: 1. a set of sites that, share some structural or functional role; 2. a set of control nonsites that lack this role, and 3. a single query site. A support vector machine classifier is built using feature vectors where each component represents a property in a given volume. Validation against an independent test set shows that this recognition approach has high sensitivity and specificity. We also describe the results of scanning four calcium binding proteins (with the calcium removed) using a three dimensional grid of probe points at 1.25 angstrom spacing. The system finds the sites in the proteins giving points at or near the binding sites. Our results show that property based descriptions along with support vector machines can be used for recognizing protein sites in unannotated structures.

Authors: De Moya Amarís Marly Esther
Published: May 2022

Approximately 80% of all the existing information in the world correspond to geo-referenced information. This creates an increasing necessity to have tools more flexible, precise and easy to use to the visualization, exploration and classification of great volumes of geospatial data. Additionally its necessary achieve smaller times to process this kind of information. In this preliminary investigation, different techniques are compared to visualize and to classify geo-referenced data using two types of neuronal networks: Kohonen's maps (SOM) and the Neural Gas method (NG). For the visualization cases, SOM showed a better performance than NG, occurring the opposite case for the classification examples.
Strategy for syntax error recovering
Authors: Báez Henry F , Vargas Juan G
Published: May 2022

This paper describes a new strategy for syntax error recovering for a complier that does not have instruction separators like ‘;’ or opening and closing brackets like ‘{‘and ‘}’: This strategy is based on 4 steps. 1. Find set of tokens (called ACEPTA set) for each non terminal symbol of the grammar 2. During the syntax analysis of each non terminal symbol, eliminate the tokens that are not in the ACEPTA set. 3. Eliminate repeated tokens that are not accepted by the grammar, and 4. Complete symbols in the syntax analysis with the hope that the token that has not been erased later will match with a terminal symbol expected by the syntax analyzer; otherwise the symbol will be eliminated in some particular productions. The strategy for syntax error recovering is a method that can be used in whatever not ambiguous context free grammar including those that use instruction separators like ‘;’. It is implemented with an algorithm and it is much more easy to implement than other strategies for syntax error recovering like those based on stacks.

Authors: García Lozada Héctor Manuel
Published: May 2022

The gases of exhaust of 25.173 vehicles that circulate in Bogotá were analyzed, between November of the 2002 and May of the 2003. Of the total of evaluated vehicles, 19.938 they consume gasoline and 5,233 vehicles operate to diesel engine. One was that the 14,7% of the vehicles to gasoline do not fulfill the limit allowed for carbon monoxide established by the environmental authority of the city and the 22,6% fail to fulfill the hydrocarbon standard. Also it was identified that the 30,8% of the vehicles to diesel engine display percentage of opacity of the smoke over the allowed limit. Of another part, one stands out that in the vehicles to gasoline that fail to fulfill the HC norm, the concentrations they exceed in more of twice the normative limit whereas in which they operate to diesel engine and that do not fulfill the opacity norm in average, the excedencia is near 45% of the allowed thing.
Kinetic study of enzymatic hydrolysis of potato starch
Authors: Pardo M. , Rivera P. , Castellanos Domínguez Óscar Fernando , González G.
Published: May 2022

This article describes the kinetic study of potato starch enzymatic hydrolysis using soluble enzymes (Novo Nordisk). Different assays divided into four groups were used: reaction time (with which it was possible to reduce the 48-72 hour duration reported in the literature to 16 hours with comparable productivity levels); selecting the set of enzymes to be used (different types were evaluated -BAN and Termamyl as alfa-amylases during dextrinization stage, and AMG, Promozyme and Fungamyl for sacarification reaction- identifying those presenting the best performance during hydrolysis). Reaction conditions were optimized for the process's two stages (dextrinization and sacarification). Enzyme dose, calcium cofactor concentration, pH, temperature and agitation speed were studied for the first stage. Enzyme ratio, pH and agitation speed were studied for sacarification; the latter parameter reported values having no antecedents in the literature (60 rpm and 30 rpm for first and second reactions, respectively). Michaelis Menten kinetics were calculated once conditions had been optimized, varying substrate from 10%-50% P/V, obtaining km and Vmax kinetic parameters for each reaction. A kinetic model was found according to local working conditions which was able to explain potato starch conversion to glucose syrup, achieving 96 dextrose equivalents by the end of the reaction, being well within the maximum range reported in the literature (94-98). Laboratory equipment was constructed prior to carrying out assays which was able to reproduce and improve the conditions reported in the literature, making it a useful, reliable tool for use in assays returning good results.

Authors: González Javier , Sánchez Carlos , Hoyos Bibian Alonso , Monsalve Carlos , Trujillo Gonzalo
Published: May 2022

This report describes the construction and evaluation of a fuel cell with a bi-metallic anode of Pt-Sn supported on carbon, as catalysts for oxidation of pure hydrogen, pure CO and a 2% CO in H2 mixture. Both, cathode and anode were made with a structure composed by a diffusive layer and a catalytic layer. The diffusive layer was made with a carbon cloth while the catalytic layer contained the platinum and tin supported on carbon. To test the performance of the catalytic mixture, a proton exchange membrane fuel cell (PEMFC) was developed with an original design for the gas distribution plates. The reactants were feed to ambient temperature and 3 psig in the anode side, while 5 psig pure oxygen was used in the cathode. The anode catalytic load was 0.57 mg/cm2 of platinum and 0.08 mg/cm2 of tin. The catalytic load in cathode was 0.85 mg/cm2 of pure platinum. It was found that this catalytic mixture is tolerant to CO presence.

Published: May 2022

Tulisan ini bertujuan membahas sejarah minoritas Islam di negara India. Minorits muslim yang ada di negara India bisa dikatakan bahwa perkembangan Islam disana masih mendapat hambatan dan tantangan yang besar dari kelompok Hindu, orang-orang hindu sangat dikenal dengan sistem kasta mulai dari kasta paling tinggi hingga kasta paling rendah, untuk kasta paling rendah ini mereka berikan kepada umat Islam yang ada disana yang mana sangat berpengaruh sekali dalam kehidupan sosial kemasyarakatannya jelas sekali perlakuan orang-orang hindu tersebut kepada minoritas muslim hanya dipandang sebelah mata. Dalam bidang politik hanya diberi kesempatan yang sangat sedikit untuk orang Islam itu sebanyak 1% selebihnya dikuasai oleh yang beragama Hindu, sedangkan dalam bidang pendidikan anak-anak muslim sangat jauh sekali berada di bawah bahkan banyak yang buta huruf, hal ini dipengaruhi oleh perekonomian minoritas muslim disana yang sangat memprihatinkan dan juga minimnya bantuan dari pemerintahan, karena beragama Islam mereka sangat kesulitan untuk mencari pekerjaan, bahkan mereka sampai menyamar dengan memakai pakaian orang Hindu demi bisa mendapat pekerjan untuk memenuhi kebutuhan hidupnya.
Kallimachos: Ektheósis Arsinoés •
Authors: Adorjáni Zsolt
Published: May 2022

E tanulmány Kallimachos az elhunyt II. Arsinoé előtt tisztelgő költeményét elemzi. Először az Ektheósis Arsinoés a költői életműben elfoglalt helyét, a műfaj kérdéseit és a mű szerkezetét vizsgáljuk. Ez vezet át a versben fellelhető irodalmi allúziók értelmezéséhez (főként Hésiodos, Ibykos, Simónidés, Pindaros). Ezenfelül részletesen tárgyaljuk a történelmi hátteret és a töredékes hagyományból származó filológiai nehézségeket. A befejező rész a kallimachosi költemény utóéletét térképezi fel a görög és latin irodalomban.

This article aims to present an overall interpretation of a poem by Callimachus on the dead Ptolemaic queen Arsinoe II. Firstly the position of the Ectheosis Arsinoes in Callimachus’ rnuvre, the genre to which it belongs and its structure will be investigated. This leads to the analysis of the highly allusive character of the work (above all to Hesiod, Ibycus, Simonides and Pindar as well as to hymnic poetry). In addition, realia (the historical background) and textual difficulties arising from the fragmentary transmission will also be treated. The conclusive part looks at the reception of Callimachus’ poem in later Greek and Latin poetry.
Az afrikai latinság és a vetus Afra
Authors: Bohacsek Dóra
Published: May 2022

Az észak-afrikai latin szerzők sajátos írásmódjára vonatkozó megjegyzéseket már késő ókori grammatikusoknál is olvashatunk, az afrikai latinság kérdése pedig hosszú múltra és változatos tudománytörténetre tekinthet vissza. Sokszor maguk a szerzők - így Apuleius, Szent Ágoston - térnek ki afrikai származásukra, többnyelvűségükre, sok esetben mentegetőzve az őket ért vádak miatt, melyek az általuk használt latin sajátosságaira vonatkoztak. Élt tehát egyfajta elképzelés a köztudatban az ókortól kezdve, miszerint az észak-afrikai területeken beszélt és használt latin nyelv bizonyos sajátosságokkal rendelkezik. Természetesen a kiejtés és a beszéd tekintetében nincsenek ellenőrző eszközeink, azonban ezek lenyomatain, az afrikai területekről származó szövegeken tetten érhetjük és vizsgálatuk révén közelebb kerülhetünk az afrikai latin nyelv esetleges jellegzetességeihez. A korai keresztény szövegek egyik legfontosabb emléke az úgynevezett Codex Bobbiensisben hagyományozódott, amely amellett, hogy a legrégebbi fennmaradt, a Kr. u. IV. századból származó latin evangéliumfordítás, a Vetus Latina szöveghagyomány afrikai (vetus Afra) tradíciójának fő képviselője is egyben. Jelen tanulmányban annak megállapítására teszek kísérletet, hogy a kódex szövegében esetleg kimutathatók-e olyan (nyelvi) jelenségek, amelyek az eddig - elsősorban az afrikai feliratos anyag elemzéséből - kirajzolódott nyelvi képünk, elképzelésünk alapján valóban afrikai sajátosságnak, africanismusnak tekinthetők.

Comments on the unique writing style of the North-African Latin writers can already be found in the ancient grammarians’ texts. The question of the African Latin language has been around for long and it also has a diverse scientific history. It was often the authors themselves - Apuleius or St. Augustine - who commented on their African ancestry, their multilingualism, and their own use of Latin. They often tried to excuse themselves for the accusations, which their (incorrect?) language use attracted. There was - already in Antiquity - a notion, that both the written and the spoken Latin of North Africa had some unique features, which set them apart from the language used in Rome. Obviously, we do not have any instruments to experience pronunciation and spoken language in antiquity, but through the study of texts written in the region, we can get a closer look on the specific features of Latin used in the region. One of the most important early Christian texts, which has been preserved in the so-called Codex Bob- biensis is a fourth century Latin translation of the gospel. This text is also the main representative of the african (vetus Afra) version of the Vetus Latina. In this article I am trying to investigate this text, to see if there are any linguistic features, which can be (based on the already existing notions we have of the language from studying the inscriptions of the region) called specifically african features („africanismus”).

Universal health system based on Primary Care and advanced practice nursing
Authors: Lopes Júnior Luís Carlos , Lazarini Welington Serra , Coqueiro Jandesson Mendes
Published: May 2022

ABSTRACT Objective: To reflect on advanced practice nursing in Primary Health Care considering the complexity of the Brazilian health system. Methods: Reflective study, based on the document “Expanding the role of nurses in Primary Health Care” and anchored in the literature and critical analysis of the authors. Results: Due to the complexity of the Unified Health System — in terms of infrastructure, human resources, funding — it is important for Brazil to carry out its own systematic process of discussion on the implementation of advanced practice nursing, considering the context of the current health care model, to define the role of this practice according to the characteristics of a universal health system and not a universal health coverage. Final considerations: The expansion of the workforce and the insertion of advanced practice nursing in Brazilian Primary Health Care needs to happen with greater recognition and incentives for the actions performed at this level of care. For example, they must occur through integration between professionals and the community in health promotion actions, with the availability of appropriate technologies for the work, in order to guarantee the quality and resolution of Primary Health Care.

ABSTRACT Objective: To identify factors associated with cognitive, emotional, psychomotor, and relational skills of informal caregivers in home care. Methods: A cross-sectional study carried out with a sample of 216 informal caregivers residing in a municipality in the state of Paraná. Data collection took place between February and July 2019, with an instrument developed and validated to assess the skills of informal caregivers. Descriptive and inferential analyses were used. Results: The factors associated with a greater competence of informal caregivers were being female, having training in the field, and having more than five years home care experience. The lowest competence was observed in caregivers who had health problems and belonged to the lowest strata of family purchasing power. Participants had lower scores in psychomotor competence and had better results in cognitive competence. Conclusion: It was found that women with experience in care had higher levels of competence to provide quality care at home assistance services.

ABSTRACT Objective: to analyze the association between sleep quality, health symptoms and the physical, psychological and social effects of work in Nursing professionals working the night shift. Method: a cross-sectional study conducted with Nursing professionals working the night shift of a hospital institution. The instruments used were a socio-occupational and health symptoms questionnaire, the Assessment Scale for Work-Related Harms, and the Pittsburgh Sleep Quality Index. Data were collected between September 2017 and April 2018.The analysis was performed by means of descriptive and analytical statistics. Results: a total of 139 workers took part in the study and a statistical difference was identified between poor sleep quality and the female gender and physical illness variables and health symptoms such as appetite disorder, sensation of indigestion, flatulence, insomnia, difficulty concentrating, unhappiness, sensation of decreased self-esteem and mood lability. Conclusion: it was verified that Nursing professionals working the night shift experienced poor sleep quality, and that this relationship exerts an impact on physical, psychological and social health. Interventions targeted at raising awareness about sleep hygiene can promote better outcomes in these individuals' health.

ABSTRACT Objective: to understand how aged people with intestinal ostomies experience this situation together with urinary incontinence. Method: a qualitative, descriptive and exploratory research study, developed with 77 aged individuals with intestinal ostomies assisted by the Unified Health System, in four municipalities from the Metropolitan Region of Florianópolis. Data collection was conducted using semi-structured interviews from October 2019 to February 2020. The theoretical framework used was Dorothéa Orem's Self-Care Theory and the data were submitted to content analysis, in its thematic modality. Results: the analysis allowed generating three thematic categories: 1) Feelings generated by the intestinal ostomy and urinary incontinence: acceptance, denial, fear, insecurity, constraints experienced due to the ostomy and to the urinary incontinence symptoms; 2) Lifestyle changes; and 3) Deficit in self-image. Conclusion: it was evidenced that, for most of the research participants, it is difficult to accept the experience of living with an intestinal ostomy and urinary incontinence, which generally produce negative feelings. However, the participants proved to be resilient and able to adapt to the changes in lifestyle. Many of these behaviors are due to the health professionals' important contribution in providing them the necessary attention, encouraging self-care strategies in both situations.

Abstract South America is home to more miniature fishes (<26 mm in standard length) than any other continent. Despite this diversity, the ecology of miniature fishes is poorly studied. To promote the study of miniature fish ecology, we investigated patterns in total richness, assemblage structure and environmental correlates for miniature fishes in the rio Jacundá drainage of the Lower Amazon River basin, Pará State. Based on multi-pass dip-netting of leaf litter at 20 locations distributed across two sites, we collected miniature species and used rarefaction to estimate 9 to 14 species might be present. The miniature fish assemblage at the upstream site was a nested subset of the downstream site, and water pH and canopy cover, two features known to be altered by deforestation, correlated most strongly with assemblage variation. Our work represents one of the first quantitative assessments of environmental correlates with miniature fish assemblages and highlights research topics that should be investigated further to promote conservation and preservation of the overlooked and understudied Amazonian diminutive freshwater fish fauna.
Testing spatial and environmental factors to explain body shape variation in the widespread Central American Blackbelt cichlid Vieja maculicauda (Teleostei: Cichlidae)

Abstract Body-shape variability may respond to the interaction between history and environment, particularly in species whose range includes known biogeographical barriers. Central America has traditionally been regarded to have functioned as a complete land-bridge connecting two continents since the Plio-Pleistocene and as an incomplete one since much earlier. This history has helped shape species diversification and distributions. Vieja maculicauda is a widely distributed cichlid, found throughout most of the Atlantic slope of Central America, across three of the four geological blocks that make up this region and whose borders are known dispersal barriers. We asked whether there is an effect of geologic blocks on body shape of V. maculicauda as determined by geometric morphometric assessment of 151 individuals from across its range. We asked how much variance in body shape is explained by environmental variables. We used a CVA and a MANCOVA to determine whether a relationship between body shape and geologic blocks exists. For testing body shape correlation against geographic and environmental variables, we used a Mantel test. Our results suggest that body shape in V. maculicauda can be segregated by geologic blocks, while the correlation results showed no strong correlation between our sets of variables.

Abstract Heptapteridae is a diverse group of catfishes composed of 231 valid species endemic to the Neotropical region, recognized in two subfamilies: Rhamdiinae and Heptapterinae. Phenacorhamdia is a Heptapterinae member and currently has 13 valid species broadly distributed throughout the main river basins of South America. Here we described a new species of Phenacorhamdia from the Xingu River basin. Morphological data were obtained from 30 specimens under 23 morphometric measures and 6 meristic counts. The new species differs from congeners based on the exclusive combination of the following diagnostic characters: atypical mottled colored body and all fins with interradial membranes mottled pigmented; multicuspid teeth; maxillary barbel reaching pectoral-fin origin; lacking a short extension of the first pectoral-fin ray; caudal fin lobes extremely elongated and pointed; and 43−45 total vertebrae.

Published: May 2022

RESUMO Este artigo tem como desafio perspectivar a disputa de forças institucionais que atuam no cotidiano escolar com o objetivo de analisar o trabalho do psicólogo na escola e refletir sobre ele. A posição que sustenta este trabalho parte de concepções desenvolvidas pela Psicologia Escolar no que concerne a análises críticas sobre a práticapsinas escolas. Utilizamos ferramental teórico-prático do Movimento Institucionalista como forma de acessar, nas relações cotidianas, o jogo de tessitura das forças instituintes e instituídas e os efeitos de naturalização e normalização dos corpos que habitam esse território. A partir de uma situação vivida no campo escolar, analisaremos algumas forças institucionais que demonstram a necessidade de o psicólogo na escola se manter à espreita de cenas cotidianas em que esses efeitos, de naturalização e normalização, são tensionados.

RESUMO O processo de produção de concreto gera um significativo impacto ambiental por ser um dos maiores consumidores de matéria-prima, como areia, pedra e água. Entretanto, o maior impacto é causado pela produção do cimento Portland, material indispensável ao concreto. A diminuição do consumo de cimento para se produzir materiais cimentícios é um importante aliado para a sustentabilidade das construções. Assim, o presente estudo avalia as propriedades reológicas, físicas, mecânicas e de difusão de íons cloreto em concreto autoadensável (CAA) com a incorporação de altos teores de pozolana da casca de arroz (PCA) e metacaulim (MK) em misturas terciárias. Para tanto, foram analisadas duas composições de concretos autoadensáveis com substituição de 40% e 50% de cimento por misturas terciárias com 20% de PCA e 20% de metacaulim e com 30% de PCA e 20% de metacaulim, respectivamente, sendo analisada ainda um CAA de referência com consumo de cimento de 450 kg/m³. Foram realizados ensaios de caracterização do CAA em estado fresco (slump flow test com T500, anel J, funil V e caixa L), além de absorção de água, índice de vazios, massa específica, resistência à compressão e migração de cloretos em regime não estacionário nos CAA após 28 dias de cura. Os resultados evidenciaram que a sinergia das misturas pozolânicas proporcionou desempenhos mecânicos e de durabilidade superiores ao CAA de referência, produzindo concretos autoadensáveis com baixos consumos de cimento de elevada resistência e durabilidade frente a cloretos.

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder that affects both fetal development and postnatal tissue growth, resulting in altered brain structures and a tumor predisposition syndrome. Although every organ system is affected by the disease, kidney involvement is a leading cause of death in adults with TSC. Over the past decade, significant progress has been made in understanding the renal disease. This review focuses on the cystic and solid renal lesions in TSC, including their pathobiology and treatment.
