Cancer in Kenya: types and infection-attributable. Data from the adult population of two National referral hospitals (2008-2012)
Authors: Macharia Lucy Wanjiku , Mureithi Marianne Wanjiru , Anzala Omu
Published: October 2019

Background: Cancer in Africa is an emerging health problem. In Kenya it ranks third as a cause of death after infectious and cardiovascular diseases. Nearly 31% of the total cancer burden in sub-Saharan Africa is attributable to infectious agents. Information on cancer burden is scanty in Kenya and this study aimed to provide comprehensive hospital based data to inform policies.

Method: A cross-sectional retrospective survey was conducted at Kenyatta National Hospital (KNH) and Moi Teaching and Referral Hospital (MTRH) from January 2008 to December 2012.  Data was obtained from the patients files and the study was approved by the KNH/University of Nairobi and MTRH Ethics and Research Committees.  

Results: In KNH, the top five cancers were: cervical (62, 12.4%), breast (59, 11.8%), colorectal (31, 6.2%), chronic leukemia (27, 5.4%) and stomach cancer 26 (5.2%). Some 154 (30.8%) of these cancers were associated with infectious agents, while an estimated 138 (27.6%) were attributable to infections. Cancers of the cervix (62, 12.4%), stomach (26, 5.2%) and nasopharynx (17, 3.4%) were the commonest infection-associated cancers. In MTRH, the five common types of cancers were Kaposi’s sarcoma (93, 18.6%), breast (77, 15.4%), cervical (41, 8.2%), non-Hodgkin’s lymphoma (37, 7.4%) and colorectal, chronic leukemia and esophageal cancer all with 27 (5.4%). Some 241 (48.2%) of these cancers were associated with infectious agents, while an estimated 222 (44.4%) were attributable to infections. Kaposi’s sarcoma (93, 18.6%), cancer of the cervix (41, 8.2%) and non-Hodgkin’s lymphoma (37, 7.4%) were the commonest infection-associated cancers.

Conclusion: Our results suggest that 30.8% and 48.2% of the total cancer cases sampled in KNH and MTRH respectively were associated with infectious agents, while 27.6% and 44.4% were attributable to infections in the two hospitals respectively. Reducing the burden of infection-attributable cancers can translate to a reduction of the overall cancer burden.

Published: October 2019

Background: This study aimed to collect data to compare blood pressure values between random-zero sphygmomanometers and automated oscillometric devices and generate equations to convert blood pressure values from one device to the other.

Methods: Omron HEM-907, a widely used automated oscillometric device in many epidemiologic surveys and cohort studies, was compared here with random-zero sphygmomanometers. In total, 201 participants aged 40-79 years (37% men) were enrolled and randomly assigned to one of two groups, with blood pressure measurement first taken by automated oscillometric devices or by random-zero sphygmomanometers. The study design enabled comparisons of blood pressure values between random-zero sphygmomanometers and two modes of this automated oscillometric device (automated and manual), and assessment of effects of measurement order on blood pressure values.

Results: Among all participants, mean blood pressure levels were the lowest when measured with random-zero sphygmomanometers compared with both modes of automated oscillometric devices. Several variables, including age and gender, were found to contribute to the blood pressure differences between random-zero sphygmomanometers and automated oscillometric devices. Equations were developed using multiple linear regression after taking those variables into account to convert blood pressure values by random-zero sphygmomanometers to automated oscillometric devices.

Conclusions: Equations developed in this study could be used to compare blood pressure values between epidemiologic and clinical studies or identify shift of blood pressure distribution over time using different devices for blood pressure measurements.

Evaluation of the effect of two commercially available non-alcoholic mouth rinses on the microhardness of composite material - An invitro study
Authors: Rajasekhar Reshma , James Baby , Johny Minimol K , Jacob Jose
Published: October 2019

Composites have been widely used for anterior as well as posterior restorations due to increased aesthetic demands. Composite restorations placed in patients oral cavity is subjected to masticatory load, pH changes and chemical effect due to mouthwashes, beverages, food etc and the detrimental effects associated with these challenges on the microhardness of composite has to be determined. The study was conducted to evaluate the effect of two commercially available non-alcoholic mouth rinses on the microhardness of micro-hybrid and nanohybrid composite resins. Forty disc-shaped composite specimens were made from each type of composite materials and were divided into 5 groups with 8 samples each, Group 1= Microhybrid+Chlorhex, Group2=Microhybrid + Hexidine, Group3= Nanohybrid + Chlorhex, Group4= Nanohybrid+ Hexidine, Group 5= Nanohybrid and Micro hybrid + artificial saliva(Control).The samples were immersed in mouthrinses for 24 hrs and microhardness was subsequently measured using a Vicker’s microhardness tester. There was no significant difference in microhardness values of tested composite resins in either mouth rinses when compared to composites immersed in artificial saliva. Non-alcoholic mouth rinses do not affect the microhardness of micro-hybrid and nanohybrid composites.

Published: October 2019

This article aimed at discussing the effectiveness of developing a new antioxidant and anti-inflammatory product from the natural source namely the extract of Leucas aspera plant that can be used to treat various oral mucosal conditions. The study was a descriptive experimental study. The dried powder extract of the whole LA plant was subjected to various procedures such as phytochemical analysis, antioxidant assay (DPPH) and assessment of anti-inflammatory effect (Cytokine activity in RAW 264.7 macrophage cells) and the results were tabulated. Significance of anti-inflammatory activity was tested by T-test. Our analysis has confirmed that 100µg of plant extract showed high amount of antioxidant activity (78%). The cytokine inhibitory percentage of our plant extract showed consistent increase when tested from 250 ug/ml to 1000ug/ml to be from 24% to 39% thus demonstrating significantly high level of anti-inflammatory potential (P > 0.01). Our study suggests that LA plant can be safely utilized for testing and developing products based on its extract.

A reescrita obsessiva da infância em dois livros de Salim Miguel: a criação de um “espaço autoficcional”
Authors: Silva Ana Cláudia De Oliveira da
Published: October 2019

Salim Miguel não escreve, ele reescreve. Seus textos consistem em uma reescrita obsessiva de fragmentos da própria infância que obstinadamente teimam em retornar para o sujeito adulto. São os mesmos pedaços de vida, mas sempre diferentes. Repetição de cenas literárias e personagens que permite pensar na construção de um “espaço autoficcional”, local onde o escritor, atravessado pela experiência da diáspora, pode expressar-se livremente, mesmo que a imagem de si mesmo oferecida ao leitor seja múltipla, fragmentária e lacunar. É o que percebemos nos livros Onze de Biguaçu mais um (1997) e Reinvenção da infância (2011), objetos deste trabalho, os quais apresentam entre os percalços da infância e juventude, uma espécie de percurso de formação pessoal, moral e literária do filho mais velho do Seu Zé Miguel, personagem construída pelo autor para ficcionalizar a própria experiência. Com base nisso, objetivamos refletir sobre a escrita autoficcional de Salim Miguel e a instauração de um pacto ambíguo com o leitor, a partir dos pressupostos teóricos de Lejeune (2008), Arfuch (2007), Alberca (2007) e outros. Nesses termos, por uma via que privilegia a relação intrínseca entre diferentes textos do mesmo autor e abarca tanto a análise textual quanto paratextual, identificou-se na produção literária do escritor líbano-catarinense a utilização de uma série de procedimentos que desconfiam de noções centralizadoras como as de sujeito, identidade e pretensão de totalidade.

Revisão histórica e identidade em Flight, de Sherman Alexie
Authors: Alves Érica Fernandes , Feldman Alba Krishna Topan
Published: October 2019

O objetivo desse artigo é analisar a revisão histórica e a busca da identidade indígena na obra Flight (2007), do escritor indígena Sherman Alexie. O romance descreve um período na vida de Zits, adolescente mestiço indígena e irlandês, órfão de pai e mãe, que passa a ‘entrar’ na pele de diversas pessoas em períodos históricos diferentes. Buscamos compreender quais são os momentos históricos discutidos em cada transformação e quais os efeitos dessas transformações na identidade do protagonista. Como base teórica, estudamos a resistência através do testemunho, conforme Ashcroft (2002) e fontes de informação sobre a história indígena estadunidense, como Brown (1970), sobre a identidade, elencamos Hall (2006), com o intuito de analisar Zits, seu deslocamento e a busca de sua identidade. Como resultado, observamos como a literatura indígena, em geral, e Alexie, em particular, se utilizam das estratégias literárias para repensar e questionar estereótipos e registros históricos que colocam indígenas como o inimigo, sem voz, taxado de selvagem.
Reconstrução dilacerada: memórias de um proscrito
Authors: Quadros Aurora Cardoso de
Published: October 2019

Este artigo, com o apoio das elaborações do Stuart Hall sobre Diáspora, tem como objetivo analisar a associação entre a estética e a vida no exílio de Ferreira Gullar, trazendo ao centro o Poema Sujo, publicado em 1976. O momento da criação, que representa a busca do passado, situa-se num período de forte tensão, devido ao recrudescimento dos assédios do Brasil, então sob o regime militar.  No impulso de deixar um testemunho da sua vida, acreditando aproveitar desse modo o tempo restante, os versos buscam reconstruir, pela palavra poética, o tempo, a vida e o espaço do proscrito. Observa-se que, ao representar sua trajetória pela arte da palavra, ele escreve a História antagônica que vive. Essa associação entre Poesia e Vida cria, no caso de Gullar, uma configuração que reforça o sentimento advindo da diáspora, pois, ao revolver sua vida, remodela os modos de dizê-la como reflexo do espírito de revolta de que se acomete. A linguagem fortalece o proposital impacto estético, e esse procedimento fortalece o enfrentamento ideológico, em radical contraposição ao conservadorismo.Palavras-chave: Poema sujo. Diáspora. Memória. Rebeldia.
Errantes, diferentes, desiguais: em torno de Os emigrantes, de W. G. Sebald
Authors: Oliveira Paulo César Silva de
Published: October 2019

Este trabalho propõe uma leitura crítica de Os emigrantes, de W. G. Sebald (2002), problematizam as dicotomias estabelecidas na modernidade entre uma promessa de mobilidade contraposta à clausura de um mundo marcado, conforme a acepção de Walter Benjamin, pelo “mal do progresso” inscrito no pesadelo da história. A ficção de Sebald se constrói nas interseções entre memória, documento, história, etnografia e ficção. Seu texto será lido como movimento de passagem que convoca a crítica à análise de uma série discursiva composta por um campo reflexivo em torno das antinomias de uma Europa moderna arrebatada no século XX pelo trauma, pela catástrofe e pela ruína. Neste sentido, Sebald dialoga com formas textuais híbridas que, por meio de uma poética do fragmento, renova o realismo literário, influenciando decisivamente a prosa ficcional contemporânea. Em Sebald, a tematização do mundo arruinado se converte em uma alegoria da era das catástrofes e do destino de sujeitos migrantes. O artigo discute as implicações teóricas e o alcance deste conjunto de temas e reflexões.
Lugares da literatura e os sentidos dos lugares: transnacionalização, deslocamentos e violência em Bernardo Carvalho
Authors: Fontes Maria Aparecida Rodrigues
Published: October 2019

Resumo: Com este artigo pretendo interrogar como os deslocamentos, sobretudo no âmbito do projeto de interacionalização da literatura, a partir de conceitos como transnacionalização e da multiplicação de temas ligados à violência, têm sido útil ao mercado editorial e, de certa forma, menos favorável aos projetos de cultura nacional. Isto nos leva a indagar acerca dos lugares da literatura e dos sentidos dos lugares, de sua autonomia em relação a outros modos de discurso, e da capacidade da ficção transnacional de se colocar numa relação ipertextual com os diferentes tecidos históricos sem destituir a obra literária da sua capacidade política de articulação sociocultural. Combinando, portanto, a ideia de deslocamento e ‘estranhamento’ como um valor suplemantar, que possibilita ajustar foco e perspectiva, veremos como  Bernardo Carvalho, em O filho da mãe, trata das questões relativas ao transnacional na literatura, através da abordagem de temas comuns às grandes cidades e aos territórios em guerra, cujas especificidades modelam e determinam o comportamento das personagens e as suas relações dentro de uma estrutura social deteriorada pelos conflitos e pela violência.
Literatura cabo-verdiana em trânsito
Authors: Lima Norma Sueli Rosa
Published: October 2019

Exame da literatura cabo-verdiana na representação de sua especificidade crioula em contato com outras culturas, a europeia e a brasileira, na busca de indagar o Outro enquanto contraponto adverso ou de seu próprio reflexo. As problematizações dessas representações se fizeram com o exame do diálogo, do ponto de vista da perspectiva diaspórica que irá reconfigurar os lugares das identidades em diferentes contextos e espaços, a partir da construção/deconstrução dos parâmetros eurocêntricos com Achille Mbembe, Kabengele Munanga, Walter Mignolo, Pires Laranjeira e Alberto Costa e Silva, entre outros a fim de se verificar a conexão entre os espaços. A conclusão é o projeto estético-histórico que uniu Cabo Verde ao Brasil, principalmente desde o Modernismo Brasileiro até à atualidade, na perspectiva que colocou em evidência o elemento africano, que se deslocou e se transformou em diferentes realidades.
Uma dolorosa aprendizagem: espaço (d)e escrita em António Lobo Antunes
Authors: Francisco Denis Leandro
Published: October 2019

Este artigo relaciona espaço e escrita nos três livros de estreia do escritor português António Lobo Antunes: Memória de elefante (1979), Os cus de Judas (1979) e Conhecimento do inferno (1980). O objetivo é, partindo das noções de território, desterritorialização e reterritorialização (Deleuze; Guattari, 1980; GUATTARI; ROLNIK, 1986), examinar o trânsito do então médico-psiquiatra Lobo Antunes pelo espaço africano durante a guerra colonial em Angola como aquilo que torna possível a escrita do texto literário ao ensejar, no escritor-em-formação, a conscientização do que Joseph Margolis (1975) definiu filosoficamente como negativities humanas – formas básicas de perda e limitação da vida e do sentido – e que Walter Benjamin (1933, 1936) relacionou à “destruição da experiência”. A análise realizada indica que, simultaneamente à desterritorialização relativa do espaço angolano pela negatividade da guerra colonial processa-se a desterritorialização absoluta do médico-psiquiatra e sua reterritorialização em escritor.
Deslocamentos contínuos: territórios e línguas em Samuel Beckett
Authors: Malufe Annita Costa , Shimbo Renata Vaz
Published: October 2019

O artigo enfoca a questão do trabalho de escrita com a língua estrangeira, e suas consequências literárias, na produção de Samuel Beckett (1906-1989), escritor e dramaturgo irlandês que optou por viver na França e escrever em francês, deslocando-se de sua língua e pátria natais, tendo mais tarde passado a se autotraduzir, propondo um trânsito constante entre o inglês e o francês. Partindo dos conceitos de território e desterritorialização, propostos pela filosofia de Gilles Deleuze e Félix Guattari, o artigo visa apontar para três principais desterritorializações que seriam responsáveis por uma poética do deslocamento e da errância constantes, que caracterizaria a obra de Beckett: desterritorialização do país de origem, da língua natal e, por fim, da linguagem verbal como um todo. O objetivo é acompanhar as linhas de deslocamento que levam suas obras, em especial as de sua prosa final, a criar uma língua singular que, paulatinamente, terá como potência a desestabilização da própria dinâmica da linguagem enquanto sistema de representação.
Sujeitos femininos desenraizados ou as novas experiências do não pertencimento
Authors: Santos Ana Cristina Dos
Published: October 2019

Este trabalho discute as novas relações com o espaço que resultam das experiências dos deslocamentos e suas consequências para as personagens femininas que configuram a chamada segunda geração do exílio – filhos de pais exilados das ditaduras latino-americanas.  Tem também como objetivo verificar de que maneira a perda dos referentes espaciais modificam esses sujeitos femininos desenraizados. Para tanto, analisam-se as personagens femininas principais dos romances Apenas diez (2006), da escritora uruguaia Marisa Silva Schultze e Pasajeros en tránsito (2013), da escritora chilena Rossana Dresdner.  Verifica-se que os romances problematizam o contínuo “estar em trânsito” das personagens e suas ambiguidades culturais que permitem, com base nas experiências do deslocamento, a construção de uma subjetividade nômade produtora de sujeitos híbridos e traduzidos. Para a análise proposta, utilizam-se os textos de Norandi (2015) e Espina Bocic; Sanhueza Comte (2014) sobre a segunda geração do exílio; de Brah (2011) e García Canclini (2009)  para as noções de espaço e deslocamento; de Said (2003) para as questões de exílio; Benedetti (1983) para o conceito de desexílio e Hall (2005) e Braidotti (2002) para as questões das identidades na contemporaneidade.

Chronic total occlusion (CTO) of the left main coronary artery (LMCA) is rare on the angiograms; Coronary Artery Bypass Grafting is the standard method of its revascularization.

To demonstrate that PCI may in some cases be a safe option for patients with a high-risk surgical category, we report a complex clinical case of revascularization of chronic total occlusion of the LMCA, left anterior descending artery (LAD), and circumflex artery (CX).

Methods
Recanalization of the occluded LMCA and LAD was performed by utilizing the support-balloon technique, and CTO wires (Miracle 3™ wire, Abbott Vascular; Runthrough® NS Intermediate wire, Terumo); LAD, CX, LMCA, and its bifurcation, were stented with 3 drug-eluting stents (Resolute Integrity DES, Medtronic); the "Culotte Stenting " technique was used for bifurcation stenting, followed by "Kissing Balloon" post-dilatation technique; proximal optimization technique was performed in the LMCA.

Results
The intervention ended without complications. 2 months after stenting, the ejection fraction increased from 20% to 38%, improved almost all parameters of the heart, Congestive Heart Failure functional class decreased to class I.

Conclusions
It should be considered that LMCA CTO lesions can be successfully revascularized with PCI in case of the selection of the suitable patient and appropriate revascularization technique.
Assessment of metabolic and hormonal shifts in patients at risk of diabetes mellitus
Authors: Tereschenko I. V. , Shevchuk V. V.
Published: October 2019

Coronary patients and patients with essential hypertension were found to have the highest levels of glycated hemoglobin (gly-Hb), specifically, of its HbAlc fraction, as was shown in screening of 615 subjects. Measurements of blood levels of gly-Hb and gly-albumin, study of pyruvate metabolism, oral glucose tolerance test, and glucose-insulin test in 74 patients with coronary disease and essential hypertension revealed a high prevalence of latent disorders of carbohydrate metabolism in this patient population, with disorders of carbohydrate metabolism manifesting primarily by an increase of blood levels of glycated proteins and by disorders of pyruvate metabolism. Glycation of blood proteins in patients with coronary disease and essential hypertension increases blood viscosity (1.6 ± 0.02), spontaneous platelet aggregation (46.59 + 2.07% vs. 18.1 ± 1.5% in control), reduces fibrinolysis, and is conducive to a parallel increase of the concentration of blood serum lipids. These patients develop disorders of insulin secretion after glucose loading, thyroid function is reduced with the deficit of tri-iodothyronine production (1.46 + 0.07 nmol/liter vs. 1.92 ± 0.1 nmol/liter in health, p < 0.05); hydrocortisone hypersecretion is observed (746.25 ± 49.74 nmol/liter vs. 358.23 + 9.8 nmol/liter in health, p < 0.001); hormonal dysfunction favors the formation of glucose toxicity mechanism in normal glycemia when no clinical signs of impaired glucose tolerance are seen.
Parathyroidin effect on cerebrovascular resistance
Authors: Chursina Yu. Ya. , Khudaverdyan D. N.
Published: October 2019

Effects of parathyroidin in various doses on cerebrovascular resistance was studied in narcotized cats by resistography. Changes in systemic arterial pressure were recorded in parallel with this. A hypotensive dose-dependent effect of the drug was revealed, which manifested at the first minute by reduction of both arterial and perfusion pressure. The reduction of perfusion pressure reflecting a drop of cerebrovascular resistance was less pronounced than arterial pressure decrease. The said parathyroidin effect did not depend on its hypercalcemic effect which manifested much later. A suppressive action of exogenous parathyroid hormone on the transmembranous release of calcium ions in the smooth-muscle cells of the vessels is believed to underlie the detected hemodynamic shifts. These data may be useful in designing schemes of therapeutic correction of cerebral circulation disorders
Stimulation of the growth of "normal" thyrocytes by lymphocytes infiltrating the tissue of diffuse toxic goiter
Authors: Krainova S. I. , Kryukova I. V. , Mkrtumova N. A. , Keda Yu. M. , Kandror V. I.
Published: October 2019

The capacity of lymphocytes isolated from diffuse toxic goiter (DTG) tissue to stimulate the proliferation of normal thyrocytes isolated from paranodular tissue adjacent to nodular euthyroid goiter was studied. Normal and DTG thyrocytes were incubated for 24 h with fetal calf serum (FCS) in various concentrations, DTG orparanodular lymphocytes, or both FCS and lymphocytes. The proliferation rate of normal thyrocytes in the presence of FCS alone increased with increase of the serum concentration, while the proliferation rate of DTG thyrocytes did not depend on the concentration of FCS. DTG lymphocytes, but not paranodular ones, stimulated the proliferation of normal thyrocytes. The growth-stimulating effect of DTG lymphocytes was paralleled by loss of normal thyrocytes sensitivity to growth factors (FCS). These data indicate a probable role of intrathyroid lymphocytes in increase of thyrocyte count characteristic of DTG and confirm a previous hypothesis on decrease in expression of surface antigens (receptors) on DTG cells under the effect of intrathyroid lymphocytes.

Seasonal Features of Transient Hyperthyrotropinemia
in newborns
Authors: Sibileva E. N.
Published: October 2019

The results of a 5-year neonatal screening of thyrotropic hormone (TTH) in 51,222 neonatal infants were analyzed to evaluate the severity of goiter endemia in the Arkhangelsk Region that is an area of mild and moderate iodine deficiency and a high-latitude region. The analysis established the following regularity: the spread of elevated TTH levels > 5 m U/l in neonatal infants was much higher in summer months. The fluctuating pattern of transient hyperthyrotropinemia was found in the contrast seasons. The magnitude of these fluctuations depended on the climatic and geographic area where the infants had been bom. The seasonal contrast range of transient hyperthyrotropinemia and the increase in the severity of goiter endemia by this criterion in summer make it possible to analyze the results of neonatal TTH screening in June to August as a more precise indicator during monitoring the severity of goiter endemia and the effectiveness of iodine deficiency prevention in high-latitude regions where environmental factors make a substantial contribution to the functional activity of the pituitary-thyroid system.
Isolated pubarche in girls
Authors: Malyavskaya S. I.
Published: October 2019

A comparative prospective analysis of the course of puberty was made in girls with isolated pubarche. The obtained clinical, ultrasonic, and hormonal data corresponding to the formation of ovarian polycystosis in girls with isolated pubarche supported the hypothesis that it is of predictive value in the formation of the polycystic ovarian syndrome (PCOS). In postmenarche, 85.4% of the girls with isolated pubarche were found to have the major clinical signs of PCOS (impaired menstrual cycle, hirsutism, acne disease, obesity, and excessive body weight) in combination with a PCOS-typical echogram in 74.8% of cases, which makes it possible to recommend its use as a screening marker to form groups at risk for PCOS.
Poéticas de la actuación desde el cuerpo la máscara y el ritual
Authors: Araque Osorio Carlos
Published: October 2019

El teatro de imágenes corporales y mascaradas se asemeja y relaciona con la mecánica del ritual, sin ser el mismo un ritual, sino una alternativa creativa en las artes y estéticas de una sociedad. ¿Cómo re-construir el mecanismo de la acción en todos los sentidos y posibles acontecimientos creativos? El entendimiento del cuerpo y su relación con la máscara se transforma en imágenes, activando la sensibilidad e inspirando otras realidades. Es un retorno a lo primigenio, a lo invisible, a lo antiguo, al nacimiento del arte, en donde la máscara es empleada para curar, exorcizar y cazar, pero fundamentalmente para propiciar niveles idílicos de ensoñación, creatividad y transformación social, cultural y artística.
Dinámica festiva y posibilidad de estar siendo: la disputa por el sentido común

Desde una comprensión compleja de la cultura como un campo específico y un acercamiento hacia los procesos culturales reproducidos con singular densidad en la dinámica festiva de los Andes bolivianos, su proceso histórico y su presente político. Esta reflexión propone hacer visible la fetichización de la cultura a partir de la identificación de tensiones y disputas entre prácticas y representaciones culturales distintas. Al mismo tiempo, a partir de esta visibilización, se pone en evidencia el “secuestro” del sentido común de las poblaciones mayoritarias.

Published: October 2019

Nowadays, cancer is one of the most important morbidity and mortality factors in the world. For these reasons, efforts have been made to optimize the treatments that are used by specialists in the oncology area. One of the main difficulties is the lack of mathematical and statistical models that allow to characterize the performance of the treatments; one of these innovative treatment trends consists of the use of magnetic nanoparticles which are incorporated into the bloodstream either in order to diagnose or transport medications to the affected areas. This paper presents the process of estimating local minimums for a particular case of a function in R3 –defined by parameters r and t– which allows modeling the kinetics of nanoparticles.

A Fourier based algorithm to estimate the period of a sampled signal
Authors: Rairán Antolines José Danilo
Published: October 2019

Given a sampled signal, in general, is not possible to compute its period, but just an approximation. We propose an algorithm to approximate the period, based on the Discrete Fourier Transform. If that transformation uses data length for multiples of the true period, some of its harmonics have null value. Thus, the best candidate to be a multiple of the period minimizes the value of those harmonics. The validation for noiseless data shows an upper bound in the error equal to a quarter of the time between two consecutive samples, whereas the result for noisy data demonstrates robustness. As application, the algorithm estimates the period of physiological signals, and tracks the frequency of the power grid in real time, which evidence its versatility

Authors: Espitia Cuchango Helbert Eduardo , Machón González Iván , López García Hilario , Díaz González Domingo Guzmán
Published: October 2019

Energy distribution systems present alterations in the voltage profile in their nodes when distributed generation elements are installed. As a consequence, tension can be risen in a level beyond the admissible. This paper presents the optimization to three fuzzy controllers located in a distribution network with radial topology. The optimization of each controller is performed using the maximum descent algorithm, which is separately carried out; thus, having a distributed approach. The interaction between generators is considered to perform this process; the results show that the adjustment of the controllers is achieved
Para decolonizar las geopolíticas del sentir
Authors: Gómez Pedro Pablo
Published: October 2019

Intentemos relacionar la colonialidad del espacio y del tiempo con la geopolítica del conocimiento y la geopolítica del sentir. En 1977 en su Filosofía de la liberación, Enrique Dussel, hizo evidente su conciente geopolítico, al hablar del espacio como campo de batalla, social, política y epistémica (Dussel, 1996). En términos geopolíticos entonces, no es lo mismo nacer en el Polo Norte, en Chiapas o en Bolivia que, en Nueva York, pues hay un muro de diferencia colonial construido durante 500 años de modernidad. La gepolítica del conocimiento es la espacialización epistemológica del saber, y así como la economía produce centros y periferias, la epistemología también lo hace. En el Norte geográfico hay sures epistémicos así como en el Sur geográfico hay nortes epistémicos.
Dulce y salada, de Jorge Panchoaga In memoriam, Río Cauca

Published: October 2019

Uno de los más importantes reportajes sobre un ecocidio es el hecho por Eugene Smith en Japón en 1971, titulado Minamata versus the Chisso corporation. La serie de fotografías del legendario Smith, registraban el daño ambiental producido por los químicos tóxicos que contenían mercurio y que la empresa desocupaba en la bahía de Minamata. La dura vida de los pescadores, sus fiestas tradicionales, contrastan en este magnífico ensayo visual con los registros de las tremendas enfermedadesproducidas en ellos, su doloroso sufrimiento, su lucha en los tribunales, sus protestas públicas, la represión policial.La intoxicación por mercurio, principalmente obtenida por el consumo de los peces de la bahía, nos ha hecho sentir desde entonces, que la actividad pesquera, es riesgosa. Y como mencionamos al inicio, es ampliamente reconocida por su enorme valor en la toma de conciencia ambiental.

Intelligent System for Determining Parking Locations in Campus Areas Using Fuzzy Logic Based on Internet of Things
Authors: Ichwana Dody , Saputra Surya Dwi , Ekariani Shelvi
Published: October 2019

The increasing use of vehicles at campus locations makes it more difficult to find an empty parking lot. This paper develops a system for determining parking locations on campus areas using cloud-based fuzzy logic and Internet of Things (IoT). NFC is used to confirm the order code of the location that has been generated by the system. At the parking location, a sensor is installed to detect parking availability. The concept of IoT has been applied to build this system. Applications on smartphone devices are used for reservations at desired parking locations via the internet. The results show that the system has been able to detect the location of empty parking lots and make reservations in the Andalas University campus environment. The application of fuzzy logic has succeeded in obtaining parking location sequences based on distance and total capacity to find the best parking location.
The Influence of Dimethoxybenfluron on Biochemical and Haematological Parameters in Rabbits

Published: October 2019

The influence of repeated i.v. administration of dimethoxybenfluron (NO-1-B) (12 or 24 mg base/kg once weekly, 10 weeks) on biochemical and haematological parameters were studied in rabbits in vivo. No significant changes were mostly found in the serum ion levels between the dimethoxybenfluron and the control groups, as well as in most of other biochemical parameters (including total protein and albumin levels). Nevertheless, the lower dose of dimethoxybenfluron caused an increase in the glucose level. Furthermore, no significant changes were mostly present also in haematological parameters in the dimethoxybenfluron groups of rabbits (a mild decrease in thrombocytes and leucocytes). The results of our study support an assumption of good tolerance of dimethoxybenfluron from the viewpoint of its influence on biochemical and haematological parameters in rabbits and may be considered of importance for a possible therapeutic use of the derivatives.
