Patrimônio natural, documentação e pesquisa
Authors: KARPINSKI Cezar
Published: November 2018

Resumo O artigo apresenta discussão sobre Patrimônio Natural a partir de pesquisa documental sobre as Cataratas do Iguaçu, paisagem que, juntamente com o Parque Nacional do Iguaçu, é considerada Patrimônio Natural da Humanidade. O principal objetivo é demonstrar que a documentação histórica sobre a paisagem contribui para a definição de um bem natural como patrimônio da humanidade. Especificamente, objetiva-se apresentar dados de catalogação e digitalização de documentos históricos, subsidiar estudos sobre “Patrimônio Natural” nas áreas da Ciência da Informação e relacionar a produção teórica e bibliográfica sobre Patrimônio Natural com a prática de pesquisa em casos específicos. A metodologia consistiu em levantamento de fontes e pesquisa in loco em bibliotecas e arquivos no Brasil e na Argentina, sendo a busca restringida aos anos de 1850 a 1920. Além disso, fez-se o registro fotográfico digital dos originais, cujas imagens foram tratadas e padronizadas para compor um repositório digital temático. Como resultado, recolheram-se livros, mapas e imagens (pinturas de paisagem, fotografias, cartões postais) que perfizeram um total de 118 obras, das quais 104 foram digitalizadas. A discussão aponta a escassez de bibliografia específica sobre o conceito de Patrimônio Natural nas áreas das Ciências Humanas e Sociais, sendo este um objeto em potencial para a Ciência da Informação, principalmente para o enriquecimento da produção já consistente sobre informação, patrimônio e memória.

Published: November 2018

Resumen Los estudios universitarios en Documentación se remontan en España a los años ochenta del siglo XX cuando comienza a impartirse la Diplomatura en Biblioteconomía en Documentación, a la que seguirán posteriormente los estudios de Licenciado en Documentación y los Doctorados en esta especialidad. El proceso de adaptación de la Universidad española al Espacio Europeo de Educación Superior tiene como resultado la aparición de los estudios universitarios de Grado en Información y Documentación. Este trabajo presenta el origen de estos estudios de Grado, su desarrollo y situación actual, pero también sus antecedentes, sin los cuales no es posible entender la realidad actual. Se analiza la denominada “crisis de los estudios de Documentación en España” y la necesidad de repensar los estudios universitarios en este país.
Surface alkali deweighting and dyeing of polyester fabric by one-bath and one-step process
Authors: Cao Jiliang , Meng Chunli , Cheng Xianwei , Pan Xingyuan
Published: November 2018

Alkali-resistant disperse dyes have attracted great attention in the wet processing of polyester textiles under alkaline dyeing conditions. In the present study, three highly alkali-resistant (HA) disperse dyes were successfully applied to the simultaneous alkali deweighting and dyeing of polyester fabric by a one-bath and one-step process. Benzyl alcohol was used as a dyeing and alkali deweighting carrier. The effects of cetylpyridinium chloride, benzyl alcohol and disperse dye concentrations as well as alkali treating temperature and time on alkali deweighting and dyeing properties of polyester fabrics were studied. HA disperse dyes had excellent dyeing performance and good fastness on polyester fabrics. Normally, the washing and rubbing fastness of the dyed fabrics could reach grades 4–5. In addition, a relatively high weight loss of about 23% was reached for the treated fabrics, which could meet the requirement of the deweighting rate for silklike polyester products. These results demonstrate that the one-bath and one-step alkali deweighting and dyeing process could be successfully employed as an effective and eco-friendly alternative for the conventional two-step alkali deweighting and dyeing process applied in the dyeing and finishing industry of polyester fabrics.
Application of a new thermal insulation layer to subgrade
Authors: Wei Haibin , Zhang Yangpeng
Published: November 2018

The use of thermal insulation has great potential for preventing frost damage to roads in seasonally frozen areas, in fact more so than in permafrost. With the aim of recycling the vast quantities of waste coal fly ash and rubber tyres in north-east China, a new combined thermal insulation layer consisting of extruded polystyrene (XPS) board and modified soil (silty clay modified with fly ash and crumb rubber) is proposed. Field tests on an insulated test section and an uninsulated control section were designed to assess the thermal performance of the sections over the change of time and depth. The thermal characteristics and the effect and mechanism of the layer were investigated. Finite-element analysis was used to evaluate its long-term performance. The results showed that the temperature regime of the subgrade varied regularly. The combined thermal insulation layer effectively protected the road surface from cold and heat erosion, elevating the freezing depth to the upper surface of the combined layer. Furthermore, the thermal insulation effect was greater for the combined layer than the use of XPS only. The finite-element analysis showed that the impact on cold resistance was more evident in the road shoulder and roadway centre than on the slope toe, and the layer will still perform normally after 50 years.

Published: November 2018

An appropriate interchange type selection would help tackle traffic problems and avoid a decreasing level of traffic service and safety. Design alternatives are usually generated according to an engineer's experience. However, some useful types may be neglected. The criteria for interchange type selection vary from one study to another, but the criterion that should be considered first is the traffic performance. In this paper, an algorithm is suggested to auto-generate design alternatives. A fuzzy-based method is also proposed to investigate traffic performance, as well as to compare and prioritise the interchange design alternatives. The method is applied to two real-world interchanges. The findings show that the traffic performance could be improved by choosing an appropriate placement for loops and directional ramps. Finally, the results imply that more money would be saved by using the proposed method.

Published: November 2018

The article states the advantages of carbothermic perovskite concentrate decomposition in comparison with hydrometallurgical methods. The papers using the carbothermic method are noted. The paper provides information on existing perovskite processing methods that found no industrial application. The results obtained when studying titanium raw material decomposition in case of CaO·TiO2 artificially synthesized perovskite are given. Artificial perovskite was synthesized in a muffle furnace where a mixture of oxides (CaO = 41,2 wt.% and TiO2 = 58,8 wt.%) was premixed for 15 minutes and then briquetted into pellets using a 15 mm steel mold on a 147 МPa hydraulic press. The temperature of CaTiO3 synthesis was 1300 °C with a holding time of 4 hours. Experiments with a different carbon excess (20 and 30 wt.% of the content stoichiometrically required to recover perovskite components) were carried out. The carbothermic process of artificial perovskite decomposition (4 g pellets) was carried out in a vacuum furnace with a graphite heater in two stages: at 1500 °C, 1 hour holding time and 10,1 kPa residual pressure in an argon atmosphere at the first stage, and at t = 1750 °C, τ = 1 h, 1,3 Pa residual chamber pressure at the second one. Reaction products were studied by X-ray diffraction analysis on the «D8 Advance Bruker AXS» diffractometer. Experimental results demonstrated the practical possibility of titanium and calcium extraction from perovskite using the carbothermic method.

The main problem in the production of bimetals (BMs) is the need to ensure adhesive interaction at the contact boundary of layers to prevent their peeling during operation. Hot forging of porous preforms (HFPP) provides the possibility of obtaining high-density powder BMs with a minimum amount of pores both in the volume of the layer material and at the layer interface to increase adhesion strength. Production of hot-forged powder BMs may involve mixing of working layer and substrate charge materials, which can lead to uncontrolled interface «blurring». This study uses the previously proposed method for pre-pressing of hard-to-deform material powder to produce «structural steel – high-speed steel» porous BM preforms. Two-layer cylindrical ∅20×30 mm samples were obtained in order to determine mechanical properties and conduct structural analysis. The BM base material was PK40 steel, and the working layer was atomized powder of M2 high-speed steel featuring satisfactory compressibility properties. The porous preforms of BM samples were pressed in a specially designed mold at a hydraulic press enabling two-sided pressing of two-layer powder moldings with predetermined distribution of layer densities and strengths. Cold-pressed BM preforms were sintered in protective environment, and then subjected to hot repressing using a laboratory drop hammer. Some preforms were examined as sintered. In addition, hot repressing of cold-pressed green preforms was performed. Satisfactory process strength of the working layer material is observed at its porosity (Pwl) in the range from 34 to 45 %. When Pwl> 45 %, powder is not molded, and at Pwl< 34 % the working layer delaminates. The maximum layer bonding strength and thermal shock resistance of BM provides the use of a flow route that involves preliminary sintering of cold-pressed preforms and subsequent hot forging. The optimum pressure of working layer pre-pressing is 145 MPa.

The paper presents the experimentally determined heating temperature of mixed chromium carbide powders and titanium bond under explosive loading on a metal substrate. Pressure of powder mixture compression in shock waves during explosive pressing was 2,5 GPa. The experiment involved recording a thermal cycle on the back side of the coated metal substrate serving as a heat receiving element. It also solved a problem of non-stationary heat conduction until the calculated and experimental thermal cycles coincided. Initial conditions were chosen assuming that the compacted material is uniformly heated to a certain average temperature by the time the shock-wave processes end. Required thermophysical properties of the compacted material were determined by the laser flash method using the LFA 427 unit («Netzsch», Germany). According to calculations, powder mixture heating temperatures were 208 °C and 225 °C for adiabatic approximation and taking into account heat transfer into the environment, respectively. The obtained values were compared with ones calculated by the increase in enthalpy during the shock wave processing (these calculations used solid material densities under normal conditions and final powder material density determined after explosive treatment to be 199 °C and 220 °C, respectively), and it was found that they differ insignificantly. Thus, the assumption of equal material density in a shock wave and solid density does not lead to a significant error and can be used for practical calculations.

Published: November 2018

The purpose of this study is to obtain highly dispersed powder suitable for spheroidization for further application in additive technologies. Volumetric reduction of the FeCl2–CaCl2melt by calcium dissolved in CaCl2produced fine iron powder. The process consisted of three stages: preparation of melts containing FeCl2and Ca, their mixing and high-temperature aging at 800 °C for 1 hour. At the end of the process the frozen melt was divided into upper and bottom parts. The product from the upper part had a specific surface area of 7,60 m2/g, and for the lower part it was 5,38 m2/g, Average particle size was 157 μm for the former and 124 μm for the latter. After ultrasonic dispersion, it was reduced to 26 μm and 71 μm, respectively. Quantitative X-ray phase analysis showed that the main phase of powder is metallic iron (more than 97 wt.%). Therefore, research originality is the use of volumetric, intensive reduction of iron from chloride melts by calcium dissolved in its chloride. The uniqueness of the study consists in the product obtained, i.e. the main part of reduced iron is in the melt volume as linear aggregates 40 to 600 μm in length, 10 to 50 μm in diameter that are easily broken by ultrasonic dispersion into individual crystals with an average size of 26 μm. The results of the study demonstrated the feasibility of calcium-thermal production of fine iron powder.

Feminism as Power and Resistance: An Inquiry into Different Forms of Swedish Feminist Resistance and Anti-Genderist Reactions
Authors: Lilja Mona , Johansson Evelina
Published: November 2018

This article explores how resistance and power are intertwined within the field of mainstream Swedish feminism, by analyzing some of its more visible expressions and strategies. These feminist resistance strategies could be described as circulating resistance (e.g., the #metoo campaign), public assemblies, the more subtle “disciplinary resistance”, and state feminism. The article illustrates how these different forms of resistance fuel different reactions from movements that reiterate different discourses of “anti-genderism”. In addition, some forms of feminism (state feminism and feminist disciplinary resistance) sometimes develop into, or overlap with, different technologies of power.

Published: November 2018

Background. Ceftaroline is one of the first cephalosporins with activity against methicillin-resistant Staphylococcus aureus (MRSA), it effectively binds to and inhibits penicillin-binding protein 2a (PBP2a). However, isolates with decreased susceptibility to ceftaroline were reported before the commercial release of the antibiotic.
The aim of this study was to provide an overview of the proteome changes occurring in MRSA isolates resistant to ceftaroline in response to sub-inhibitory concentrations of cell-wall active antibiotics.
Materials and methods. Ceftaroline-resistant mutants were generated from two MRSA SA0077 and SA0422 isolates belonging to ST8-t008-SCCmec IV genetic lineage (sequence type 8, spa type t008, staphylococcal chromosomal cassette mec type IV) and one MRSA isolate SA0085 belonging to ST239-t631-SCCmec III genetic lineage (sequence type 239, spa type t631, staphylococcal chromosomal cassette mec type III). Proteome response of parental and mutant strains to sub-inhibitory concentration of beta-lactams and vancomycin was analyzed.
Results. The protein patterns revealed significant increase of 30 кDа band in mutant strains under induction by meropenem, no changes were observed in parental strains or under induction with other antibiotics. According to MS analysis, three proteins represented the band of the mutant strain in absence of meropenem induction. However, under meropenem induction additional protein was detected (BlaZ).
Conclusion. The cross talk between two systems with overlapping functions involved in transcription control of PBP2a and BlaZ ensure ceftaroline resistant phenotype.

Published: November 2018

Background: Metabolic syndrome is a clustering of risk factors that increase an individual’s probability of developing atherosclerotic cardiovascular disease, type 2 diabetes mellitus and all cause mortality. Since primary NAFLD has strong association with metabolic syndrome as a whole and various components of metabolic syndrome, it is being debated whether NAFLD is a hepatic component of metabolic syndrome. Hence this study was done to study the prevalence of non-alcoholic fatty liver disease in healthy individuals and in patients with metabolic syndrome and to establish a relationship between NAFLD and Metabolic syndrome.Methods: A total of 122 patients - 61 with metabolic syndrome and 61 without metabolic syndrome fulfilling inclusion and exclusion criteria who presented to the Medicine outpatient Department of Ramaiah Medical College, Bangalore, between October 2014 and September 2016 were included in the study. Baseline variables, laboratory parameters, ultrasound abdomen findings were compared between the groups.Results: Mean age of the subjects in metabolic syndrome group and non-metabolic syndrome group were 52.4±15.4 and 50.7±15.4years respectively. Mean triceps skin fold thickness (in cms) for the subjects in metabolic syndrome group and non-metabolic syndrome group were 19.16±6.1 and 7.59±2.57 respectively (P <0.05). Prevalence of fatty liver on ultrasonography in metabolic syndrome and non-metabolic syndrome were 42.62 % and 21.31% respectively. Overall prevalence of NAFLD was 31.97 %.Conclusions: Overall prevalence of NAFLD from current study was 31.97%. The prevalence of NAFLD was significantly higher in persons with metabolic syndrome than persons without metabolic syndrome.

Background: Irritable bowel syndrome (IBS) is a functional disorder of gastrointestinal tract with unclear aetiology and no reliable biomarkers like other chronic and functional disorders. Majority of the patients of IBS suffer from various forms of psychosomatic disorders as comorbidity that further exaggerate the complexity of diagnosis and management of IBS. The aim of the present study was to find the prevalence of commonly associated psychosomatic symptoms associated with IBS in the patients of lower socioeconomic strata.Methods: This is a prospective observational study carried out over a period of 10years from November-2007 till October-2017, in HAHC hospital attached to Hamdard Institute of Medical Sciences and Research. A structured questionnaire comprising of a total of 36 closed ended questions was designed. Eleven questions were about the demographic characteristics and twenty-five were pertaining to IBS symptoms according to Manning and Rome III criteria with some necessary modifications. Various psychosomatic illnesses were recorded separately after ruling out the organic cause with appropriate investigations.Results: In the present study out of 4000 patients with IBS symptoms, 70.8% were having some form of psychosomatic symptoms, Patients with psychosomatic disorders were significantly more often young in age and females (53.28%), showing highest number of patients belonging to the age group 26-35years (51.44%). 34% patient had two or more psychosomatic illnesses. Headache (62.26%) and insomnia (63.03%) were the commonest followed by chest pain (36.54%). Chest pain (77.68%), headache (62.26%) and insomnia (56.07%) was more common in male whereas palpitation (60.58%) and breathlessness (57.68%) was more common in female.Conclusions: There is significantly high prevalence of psychosomatic illness in the patients of IBS in the low socio-economic strata. The young patients (productive age group) are more affected which may be responsible for further deteriorating their social and economic condition.

ENSAIO TEÓRICO SOBRE A BUROCRACIA EM WEBER, O CONFLITO DE AGÊNCIA E A GOVERNANÇA CORPORATIVA: UMA REFLEXÃO SOBRE A BUROCRACIA PROFISSIONALIZANTE
Authors: Godoi Alexandre Franco , Silva Luciano Ferreira , Cardoso Onésimo Oliveira
Published: November 2018

Este ensaio teórico tem como principal objetivo discutir questões acerca das relações existentes entre a burocracia em Weber, o conflito de agência e a Governança Corporativa. Para tanto, destaca-se que a burocracia é vista muitas vezes nas Teorias Administrativas como fator que engessa e limita as organizações, embora seus elementos constituintes proponham um ambiente organizacional constituído de profissionalização e transparência. Assim, a proposta para racionalização das atividades organizacionais visa uma formalidade, impessoalidade e profissionalismo para garantir melhor uso dos recursos e processos. A burocracia propõe a separação das atividades referentes ao cargo e pertences da organização, das atividades e pertences privados do ocupante do cargo, evitando que interesses pessoais se confundam com interesses da organização. Do mesmo modo, a Governança Corporativa objetiva superar o conflito de agência que surge com a separação entre propriedade e a gestão empresarial, assegurando que o comportamento dos executivos esteja alinhado aos interesses dos acionistas, o que leva a proteger a organização de possíveis abusos da diretoria executiva. Outro aspecto importante destacado neste ensaio teórico trata-se do empoderamento, orientado para os interesses dos stakeholders e dos indivíduos por uma burocracia profissionalizante.

La prevalencia al nacimiento de hipotiroidismo congénito fue descrita en México, hace más de 10 años.OBJETIVO: Presentar información actualizada de la prevalencia de hipotiroidismo congénito del Programa de Tamiz Neonatal de la Secretaría de Salud y compararla con la reportada previamente en el país.MATERIALES Y MÉTODOS: Estudio retrospectivo de recién nacidos tamizados en las unidades médicas de la Secretaría de Salud del 1 de enero de 2017 al 31 de mayo de 2018. Se cuantificó la hormona estimulante de la tiroides (TSH) en sangre neonatal. Se revisó la bibliografía de la prevalencia al nacimiento de hipotiroidismo congénito (publicaciones del 2000 a la fecha).RESULTADOS: En 1,267,122 muestras adecuadas para el procesamiento bioquímico se encontraron 3,337 con TSH >10 mU/mL. Se confirmaron 923 casos, de los que 564 (61.1%) fueron niñas. La prevalencia al nacimiento fue de 7.3 por 10,000 recién nacidos. En la revisión bibliográfica solo se encontraron dos estudios con datos nacionales desglosados por entidad federativa, con una prevalencia de 4.1 y 4.3 x 10,000 recién nacidos.CONCLUSIÓN: La prevalencia al nacimiento de hipotiroidismo congénito en los recién nacidos de la Secretaría de Salud de México fue de 7.3 x cada 10,000 recién nacidos tamizados, lo que significa que uno de cada 1,373 tiene esta condición; las niñas son las más afectadas. El hipotiroidismo congénito aumentó 1.8 veces en los últimos 14 años.PALABRAS CLAVE: Tamiz metabólico; hipotiroidismo congénito; hormona estimulante de la tiroides.
¿Qué aspectos considerar al iniciar el tratamiento nutricional para Fenilcetonuria?
Authors: López Mejía Lizbeth , Vergara Vázquez Mónica , Guillén López Sara
Published: November 2018

La fenilcetonuria clásica (PKU) es una enfermedad genética en la cual el metabolismo del aminoácido esencial fenilalanina (PHE), se ve obstaculizado por la deficiencia de una enzima llamada fenilalanina hidroxilasa, como consecuencia de este bloqueo los niveles de PHE se acumulan en sangre y otros tejidos, causando daños graves e irreversibles a nivel del sistema nervioso central. El objetivo del tratamiento nutricional consiste en proporcionar una cantidad específica de PHE y al mismo tiempo dar la cantidad de proteína que requiere el paciente para crecer y evitar deficiencias asociadas a la eliminación de alimentos altos en proteína, además de mantener un funcionamiento mental adecuado. El tratamiento nutricional inicialmente, requiere del uso de una fórmula sin PHE, que provea al paciente las proteínas que necesita además de vitaminas y nutrimentos inorgánicos. En los pacientes con PKU es necesario ofrecer lactancia materna, sin embargo no puede ser de forma exclusiva ya que debe combinarse con una fórmula libre PHE.PALABRAS CLAVE: Fenilcetonuria, terapia nutricional, tamiz neonatal, lactancia materna.

Diante dos aspectos envolvidos na retenção de água pelo solo e da influência sofrida pela mesma em razão dos diferentes manejos adotados, realizou-se este estudo para avaliar a retenção de água no solo e o índice S no diagnóstico da qualidade estrutural do solo sob diferentes sistemas de manejo. O trabalho foi conduzido em julho/agosto de 2013 nas instalações do Departamento de Ciência do Solo da Universidade Federal de Lavras. Coletou-se amostras indeformadas na camada de 0 a 20 cm em um Latossolo Vermelho distroférrico sob os seguintes usos: plantio convencional de milho, plantio de café, plantio de eucalipto e um referencial de equilíbrio (mata nativa). As amostras indeformadas foram submetidas aos potenciais matriciais de -2; -4; -6 e -10 kPa em unidade de sucção, com funis de placa porosa e em câmara de Richards de média pressão a -33 e -100 kPa e alta pressão para -500 e -1500 kPa. A estrutura do solo foi avaliada com base nos atributos: densidade do solo, porosidade total, macroporosidade e microporosidade determinados pelo método do anel volumétrico. Para cálculo do índice S empregou-se a equação apresentada por Dexter que é utilizada quando o ajuste é feito pelo modelo de van Genuchten. Os resultados mostraram que o solo de mata possui maior capacidade de drenagem da água em relação aos outros manejos do solo. E em todas as condições avaliadas os valores de índice S foram superiores a 0,050, o que indica uma boa qualidade física do solo sob os diferentes manejos adotados.

Suppurative Thrombophlebitis of the Inferior Vena Cava Resolved with Intravenous Antibiotic Therapy: A Case Report
Authors: Talebi-Taher Mahshid , MD MPH , Hajsadeghi Shokoufeh , Iranpour Aida , Pahlavani Seyed Mahdi
Published: November 2018

Inferior vena cava (IVC) thrombosis is a rare medical condition. Suppurative thrombophlebitis of the IVC is even a more uncommon subtype of IVC thrombosis and is mostly associated with IVC filters or venous catheters. We describe a 66-year-old man with persistent fever and history of pyonephrosis secondary to transurethral lithotripsy 1 month before recent admission. Computed tomography scan of the chest and abdomen revealed a filling defect in the IVC protruding into the right atrium. Transesophageal echocardiogram (TEE) revealed a large mass at the origin of the IVC entering into the right atrium, suggestive of a clot. Diagnosis of suppurative thrombophlebitis of the IVC secondary to a retroperitoneal abscess was made, and intravenous antibiotic therapy for 6 weeks without anticoagulation conferred ample thrombus resolution. Follow-up TEE in week 16 showed no residual thrombus in the IVC.

Authors: Moshki Mahdi , Hashemizadeh Haydeh , Khajavi Abdoljavad , Minaee Shima , Vakilian Farveh
Published: November 2018

Background: Unraveling the relationship between health-related quality of life (HRQOL) instruments and the International Classification of Functioning, Disability, and Health (ICF) seems essential due to the increasing importance of quality of life evaluations in patients with heart failure (HF) and the use of the ICF for comparative purposes. The aim of this study is to identify and compare the content of HRQOL instruments for HF using the ICF coding system. Methods: In a 2-stage design, first we will identify all measures used to assess HRQOL for patients with HF and second we will compare the content of those measures using the ICF coding system.  Systematic search will be performed in in MEDLINE, CINAHL, and Scopus databases using a combination of free texts and MeSH terms between January 1960 and January 2017. All instruments will be linked to the ICF separately by 2 reviewers according to 10 linking rules developed for this purpose. The degree of agreement between the reviewers will be calculated via the kappa statistic. Discussion: The results of this study may help clinicians and researchers to select the most appropriate outcome measure according to the ICF-based content validity.   ROSPERO Registration number: CRD42015025380.

La historia de los artefactos itinerantes de la Plataforma de Las Águilas y los Jaguares de Chichén Itzá, México
Authors: Sellen Adam Temple , Grecco Pacheco Daniel
Published: November 2018

Este artículo intenta presentar la historia de la circulación de un conjunto de objetos arqueológicos recuperados en el siglo XIX por los exploradores Augustus Le Plongeon y Alice Dixon Le Plongeon en una ofrenda proveniente de la Plataforma de las Águilas y los Jaguares de Chichén Itzá, México. Al estudiar este conjunto de artefactos, analizamos las trayectorias e itinerarios de circulación de los objetos para comprender la materialización de subjetividades, memorias y elementos sociales en las piezas, así como para percibir usos y reutilizaciones realizadas a través del tiempo y en contextos diferentes. Para ello, utilizaremos el concepto del “itinerario” de los objetos, que trata de captar su complejidad a través de su propia dinámica, y en el desarrollo de tal argumento adoptamos como metodología la arqueología de archivo. Creemos que mediante el uso de dicho enfoque será posible recuperar historias, memorias y cuestiones sociales relativas a los objetos antiguos y así contribuir a una mejor comprensión e interpretación del pasado.
Hunab Ku, revisión de una deidad en la Historia de Yucatán de Fray Diego López Cogolludo
Authors: Cruz Cortés Noemí
Published: November 2018

En diversos estudios sobre la religión maya se menciona a un dios particular: Hunab Ku. Se trata de una deidad creadora que, de acuerdo con las fuentes históricas, no tenía representación y era incorpóreo. Aunque algunos investigadores han puesto en duda su autenticidad, aún no se determina si fue o no una deidad maya prehispánica. Tal vez el problema radica en que los datos sobre Hunab Ku son utilizados sin considerar el contexto histórico en el que se enunciaron y se registraron.     Por lo anterior, este artículo tiene como objetivos conocer, identificar y analizar a Hunab Ku en la Historia de Yucatán de Diego López Cogolludo, que es una de las fuentes principales que da cuenta de su existencia, además de comprobar si es una deidad de origen prehispánico o se trata un título del dios cristiano “traducido” a la lengua maya. Para conocer el porqué López Cogolludo habló sobre Hunab Ku es necesario recurrir al método hermenéutico propio del análisis histórico y comprender su obra dentro de su propio contexto historiográfico, así como la construcción de su discurso histórico, al considerar estos aspectos podremos entender quién fue Hunab ku.

Luka bakar disebabkan karena kerusakan atau kehilangan jaringan akibat kontak dengan sumber panas. Pengobatan luka bakar dilakukan dengan mengembalikan fungsi dan bentuk jaringan kulit kembali. Penggunaan tanaman herbal sebagai alternatif pengobatan luka bakar meningkat karena minimnya efek samping yang ditimbulkan. Kulit semangka (Citrullus lanatus (Thunb.)) mempunyai kandungan alkaloid berupa sitrulin yang berperan dalam proses penyembuhan luka serta kulit manggis (Garcinia mangostana L.) memiliki kandungan flavonoid berupa xanton  yang memiliki efek anti inflamasi dengan memicu pembentukan kolagen yang berperan penting dalam pemeliharaan struktur dan penyembuhan luka. Penelitian ini bertujuan mengetahui pengaruh gel kombinasi ekstrak kulit semangka dan kulit manggis yang memiliki efek antiinflamasi pada luka bakar yang terdapat pada punggung kelinci serta kontrol kualitas sediaan gel yang dibuat. Pengujian mutu fisik gel yang dilakukan meliputi uji organoleptik, pH, homogenitas, viskositas, daya lekat, daya sebar, daya proteksi dan aseptabilitas pada penyimpanan hari ke-0 sampai hari ke-28. Uji aktivitas gel dilakukan pada 7 ekor kelinci yang dibagi dalam 7 kelompok perlakuan yang terdiri dari kontrol negatif, kontrol positif, KS (100), KM (100), KSKM(25:75), KSKM (50:50), KSKM (75:25). Setiap kelinci dibuat luka bakar menggunakan lempeng logam panas berdiameter 2 cm. Pengukuran diameter luka dilakukan selama 14 hari. Hasil penelitian menunjukkan bahwa gel kombinasi ekstrak kulit semangka dan kulit manggis dapat menurunkan diameter luka bakar. Formula efektif yaitu formula KSKM 75:25 dengan rata-rata diameter 1,29 cm.
