Published: January 2021

Introduction. Nephrolithiasis consists of the production and retention of calculi in the urinary tract. It is being diagnosed in an increasing number of people of any age, and is one of the most common ailments in the world. Depending on a number of factors, it can be found in 5–20% of the population. Traditional surgeries are being replaced by less invasive methods of treatment. The relation between the endourological removal of calculi from the urinary tract and the assessment of the quality of life of patients who have undergone such procedures is an interesting topic worth analysing. In the 21st century, quality of life became the indicator of the efficacy of many therapies and procedures. It is associated with the quality of treatment, reflecting a better and longer life with the disease.

Objective. The objective of this study is to demonstrate the quality of life of the surveyed patients with nephrolithiasis after the endourological removal of calculi from the urinary tract.

Materials and methods. The group of surveyed individuals qualified for statistical analysis included 120 people diagnosed with nephrolithiasis. The patients underwent the procedure of the endourological removal of calculi from the urinary tract in 2015 in three hospitals in eastern Poland. Among the respondents, 48% of them underwent extracorporeal shock wave lithotripsy (ESWL), 31% had percutaneous nephrolithotripsy (PCNL), and 21% had uretherorenoscopic lithotripsy (URS). To evaluate the quality of life, a research tool was devised based on an abbreviated version of the Polish adaptation of the WHOQOL – BREF questionnaire. Also, a personal questionnaire prepared by the author was used.

Results and conclusions. The analysis of the collected materials demonstrated the impact of the endourological removal of calculi from the urinary tract on the quality of life of the hospitalised patients. Differences were identified in individuals’ general rating of quality of life (57% of respondents were satisfied) and patients’ general satisfaction with their health (47.5% of respondents were satisfied) after the procedure. Significant differences were identified in each of the studied fields: physical, psychological, social and environmental. A statistically significant correlation of p

The selecting represents the optimal selection of that part of the anthropological status that is important for the success in the respective sport and that meets the specific needs of the athlete and also for the potential athlete’s orientation and perfection in terms of certain sports disciplines.

Regarding the selection of the working methods in this research, there were selected those methods which are supposed to help in drawing conclusions about the nature of the problem posed. The sample was defined as students aged 12 years from the Middle School "Selami Hallaqi" Gjilan. In this study is included a total of 90 students, that is, two groups of 45 students. The first group is consisted of students who besides regular hours of physical education 2 times a week also exercised karate two more times a week by one hour per day. The second group comprised of students who besides regular hours of physical education 2 times a week, also exercised football two more times per week, by an hour a day. Measurements were made at the end of the school year. 9 motor variables were applied (Kurelić et al., 1975), running in 20 meters (MT20V), the long jump from the place (MSKDM), high jump from the place (MSKVM), hand taping (MTRUK), leg taping ( MTNOG), eight with bowing (MOSPR), running sideways (mtrs) bowing ahead in the bank (MFLPRK), legs spread apart-retaliation (MFLSP). For the processing of the results it was applied the t-test analysis for independent samples.

The basic statistical parameters of the results obtained from the students involved in the research show that the values obtained do not have an outlined asymmetry and incline to the lowest (hypo cortical). Taxonomic analysis shows that were obtained applying two groups of students divided by motor skills and gained distinction in these variables between groups is statistically significant.

The second taxonomy of the motor skills shows that from the 90 students, young sportsmen involved in research, 56 of them can be defined as a student athlete with high motor skills to perform motor movements with explosive character which are well coordinated in time and space, with a top speed of movement segment. Motor dimensions of the explosive strength, speed segment, coordination and flexibility are important motor skills for success in a big number of sports (Findak et al., 1992; Popović, 1998).
Effect of Drupe size Grading on in Vivo and in Vitro Germination and its Dormancy Mechanism of Teak (Tectona grandis Linn. F)
Authors: Masilamani Poomaruthai , Rajanbabu Venugopal , Venkatesan Subramanian
Published: January 2021

The effect of drupe size on in vivo and in vitro germination and its dormancy mechanism in teak have been studied in this paper. Teak drupes were size graded to five categories namely very large with more than 15 mm, large with 13 to <15 mm, medium with 11 to <13 mm, small with 9 to <11 mm and very small with less than 9 mm of diameter. Under in vivo pot culture condition very low germination percent of drupes was observed. It was observed that very large size drupe had highest 100 drupe weight, 100 true seed weight and seed filling capacity, but it was negatively correlated with in vivo germination of teak drupes. When true seeds isolated from the drupes were grown under in vitro condition in half strength MS medium the germination percent was significantly increased up to 54.1. True seeds obtained from small size graded drupes recorded highest germination per cent in MS media. This showed that the drupe size did not play major role in the germination and early growth in teak. Very small size graded drupes have low seed filling capacity, and it leads to decrease the germination percent. Poor germination of drupes showed the presence of mechanical and physiological dormancy in drupes. Similarly, the presence of morphological and embryo dormancy in teak may limit the true seed germination potential to 54.1 per cent. In addition, in vitro germination of true seeds will be a promising approach to obtain large number of saplings in teak.

Abstract. Alenezi AK, Hassan KAG, Amr TEE, Alsolais A. 2021. Impact of cognitive-behavioral therapy on daily living skills of high functioning autistic children with anxiety disorders. Nusantara Bioscience 13: 41-46. Cognitively Behavioral Therapy (CBT) is a psychotherapeutic intervention that is used to improve mental health. It is known to have positive effect on the daily living skills of autistic children with anxiety disorders. The aim of the current study was to evaluate the effect of cognitive-behavioral therapy on daily living skills of high functioning autistic children with anxiety disorders. A Quasi-experimental research design was adopted in this research. A purposive sample of 100 autistic children (50 in intervention group and 50 in control group) aged between 7-8 years were included in this study. Three main tools were used: Vineland Adaptive Behavior Scale used to measure the everyday living skills of children, Parent-Child Interaction Questionnaire (PACHIQ), and Diagnostic and Statistical Manual of Mental Disorders (DSM-V) for assessing anxiety disorder in children and adolescents 6-18 years. The results showed an improvement in children’s daily life skills and slight reductions in caregiver’s participation in the daily life skills of children. There was a significant difference between intervention group and control groups (p < 0.001). The current results exhibit that CBT may help in increasing autistic children's independence towards daily living skills.
Authentifizierung – Grundlagen einer Theorie zu sozialsymboli-schen Praktiken der Identifizierung und Zugangskontrolle
Authors: Vogel Friedemann
Published: January 2021

This paper presents elements of a theory of “authentification”. The focus is on socio-semiotical practices of identification and access control as part of social struggles for the distribution of limited resources. Within this conceptual framework, the fuzzy concept of “authenticity” can be dissolved and the habitual, temporal, modal and media constituents of the negotiation of authentication and authorisation can be brought to the fore. The theoretical considerations are illustrated with examples from the field of security industry (bouncers), cryptography and social media.
Authentizität – diskursives Wertkonzept und wissenschaftliche Kategorie
Authors: Kämper Heidrun
Published: January 2021

The authentic as a category of description and value is on the one hand an element of public discourse in order to constitute authenticity and truthfulness in various everyday contexts, on the other hand represents a central object of cultural studies. The functional difference in use resulting from this diversity of the concept is included in the following contribution, which is on the one hand in the context of the research network “Historical Authenticity” of the Leibniz Scientific Association. On the other hand, the considerations are derived from a planned research project on a linguistic social history 1933 to 1945.

Newer developments in use and changes in the semantic structure of authentic and the word family are reconstructed in order to answer the question of authenticity as a social construct. On the basis of this finding on the general use of authentic/authenticity, considerations follow, concerning the handling of such language data in the context of language history writing, which are not authentic in the strict sense, i. e. genuine and original. It is about the predicate “authentic” in terms of language data. More precisely, the category “authentic” is placed as a valuation term in the context of language history with the question: What is an authentic language date?

Low-complexity adaptive radius outlier removal filter based on PCA for
lidar point cloud denoising
Authors: Duan Yao , Yang Chuanchuan , Li Hongbin
Published: January 2021

In autonomous driving, cars rely on light detection and ranging (lidar)
to navigate the surroundings, but interference from the environment
makes it difficult to retrieve useful information. To address this
problem, this paper develops a noise reduction method to filter lidar
point clouds (i.e., an adaptive radius outlier removal filter based on
principal component analysis). We believe this method can outperform
existing clustering algorithms when applied to point cloud images
captured at a large distance from the lidar. Compared to traditional
methods, the proposed method has higher precision and recall with an
F-score up to 0.876 and complexity reduced by at least 50%.
Nonlinear beam matching to gas-filled multipass cells

Published: January 2021

Gas-filled multipass cells are an appealing alternative to capillaries to implement nonlinear temporal compression of high energy femtosecond lasers. Here, we provide an analytic expression for stationary beam coupling to multipass cells that takes into account nonlinear propagation. This allows a constant beam size on the mirrors and at the cell waist, thereby making the optical design more accurate, for example to avoid optical damage or significant ionization. The analysis is validated using spatio-temporal numerical simulations of the propagation in a near-concentric configuration. This is particularly important for multipass cells that are operated in a highly nonlinear regime, which is the current trend since it allows a lower number of roundtrips, relaxing the constraint on mirror coatings performance.
How stable are the collagen and ferritin proteins for application in bioelectronics?
Authors: Kolay Jayeeta , Bera Sudipta , Mukhopadhyay Rupa
Published: January 2021

One major obstacle in development of biomolecular electronics is the loss of function of biomolecules upon their surface-integration and storage. Although a number of reports on solid-state electron transport capacity of proteins have been made, no study on whether their functional integrity is preserved upon surface-confinement and storage over a long period of time (few months) has been reported. We have investigated two specific cases—collagen and ferritin proteins, since these proteins exhibit considerable potential as bioelectronic materials as we reported earlier. Since one of the major factors for protein degradation is the proteolytic action of protease, such studies were made under the action of protease, which was either added deliberately or perceived to have entered in the reaction vial from ambient environment. Since no significant change in the structural characteristics of these proteins took place, as observed in the circular dichroism and UV-visible spectrophotometry experiments, and the electron transport capacity was largely retained even upon direct protease exposure as revealed from the current sensing atomic force spectroscopy experiments, we propose that stable films can be formed using the collagen and ferritin proteins. The observed protease-resistance and robust nature of these two proteins support their potential application in bioelectronics.

Background and aims

Hepatitis C virus (HCV) genotyping is a pivotal tool for epidemiological investigation, guiding management and antiviral treatment. Challenge existed in identifying subtypes of genotype-1 (G-1) and genotype (GT) of indeterminate. Recently, the Abbott HCV RealTime Genotype Plus RUO assay (HCV GT Plus) has been developed aiming to overcome the limitations. We aimed to evaluate the performance of the assay compared with 5’ UTR sequencing in clinical samples.

Materials and methods

Eligible individuals were treatment chronic hepatitis C patients that were enrolled consecutively in a medical center and two core regional hospitals in southern Taiwan from Oct 2017 through Aug 2018. The patient with genotype 1 without subtype and indeterminate previously genotyped by Abbott RealTime HCV GT II will further determinate by Abbott HCV RealTime HCV GT Plus. All of the genotype results were validated by 5' UTR sequencing as a reference standard.

Results

A total of 100 viremic CHC patients were recruited, including 63 G-1 patients (male: 28), and 37 patients (male: 15) of indeterminate genotyped by Abbott RealTime HCV GT II assay (HCV GT II), respectively. The detection rate of 63 GT1 samples without subtype were 93.7% (59/63), 37 indeterminate samples without genotype were 62.2 (23/37) by HCV GT Plus. 5' UTR sequencing confirmed HCV GT Plus characterized results for 84.7% (50/59) of type1, with 100% (4/4), 82.8 (24/29) and 84.6% (22/26) for 1a, 1b and type6; 65.2% (15/23) of indeterminate with 100% (3/3) and 60% (12/20) for 1b and type 6 samples, respectively.

Conclusions

The Abbott RealTime HCV GT Plus RUO assay provides additional performance in GT detection.
The Impact of IEEE 802.11 Contention Window on The Performance of Transmission Control Protocol in Mobile Ad-Hoc Network

Published: January 2021

A Mobile Ad-hoc Network (MANET) is a group of nodes connected via ad-hoc fashion for communicating with each other through wireless interface. The communication among the nodes in such network take place by using multi-hop in the absence of fixed infrastructure. TCP faces some hurdles and complexities in multi-hop ad-hoc networks particularly congestion and route failures. The incompatibility between the MAC and TCP are previously noticed by the research community. This research study focuses on the impact of MAC layer contention window on TCP in MANET by using variation in network density and velocity of nodes respectively. Simulation has been carried out to quantify and analyze the impact of Contention Window (CW) sizes that affects the performance of TCP by using NS-2 simulator. The impact of CW is investigated on TCP in multi-hop networks by means of performance evaluation parameters i.e. average delay, average packet drops and average throughput.

Entre 2018 y 2020 hemos desarrollado, por iniciativa de la Junta de Castilla y León, el Proyecto de Investigación Roma frente a Cántabros y Astures. Su finalidad fundamental ha sido generar un instrumento de gestión, conocimiento y protección que incluyese todos los establecimientos militares romanos localizados en Castilla y León y relacionados con este periodo histórico. El desarrollo del proyecto ha conllevado la introducción, en el catálogo general de yacimientos, de otros campamentos romanos hasta ahora inéditos. De hecho, las labores de prospección y teledetección que hemos llevado a cabo en las provincias de Palencia y Burgos han permitido incrementar en varias decenas el catálogo de recintos militares conocido. En este trabajo, en el que hemos prestado especial atención a los conjuntos identificados alrededor de Herrera de Pisuerga y en la cuenca del Burejo, así como a los presentes en el camino natural entre Sasamón y Abia de las Torres, presentamos un bloque notable. La identificación de estos nuevos emplazamientos proporciona una base sólida que permitirá avanzar notablemente en el conocimiento de la presencia militar romana en esta región entre las guerras cántabras y los ss. I-II d. C.
Tres conjuntos monetales de la destrucción del oppidum iberorromano de Libisosa (Lezuza, Albacete)
Authors: Uroz Rodríguez Héctor , Arévalo González Alicia
Published: January 2021

El presente trabajo se centra en el análisis de tres conjuntos monetales recuperados en el oppidum de Libisosa (Lezuza, Albacete). Suman un total de 53 monedas de bronce, distribuidas entre dos calles y un pequeño departamento del barrio iberorromano, sede de una oligarquía local enriquecida por el comercio y con un temprano contacto con el agente itálico. No son tesorillos, sino el resultado de la destrucción instantánea del poblado en el marco de las guerras sertorianas. Cada lote está formado por un homogéneo número de piezas tardorrepublicanas, en su inmensa mayoría acuñaciones de la ceca de Castulo (por tan solo una unidad de Obulco, otra de Bolskan y un semis romano). El estado de las monedas, su caracterización y datación a principios del s. I a. C. están indicando que en Libisosa se tiende a usar numerario reciente compuesto por las especies más inmediatas y fácilmente asequibles. En términos macrohistóricos, su estudio resulta de vital importancia para el conocimiento de la circulación monetaria de ese período ibérico final/tardorrepublicano en esta zona. En términos internos, nos permite plantear la existencia de una secuencia fruto del intento parcialmente frustrado de poner a salvo el numerario de un puesto de pago o cambio monetario.
The Image of the Latins in Late Byzantine Epistolography
Authors: Szegvári Zoltán
Published: January 2021

Az értekezésem a latinok, vagyis nyugatiak reprezentációját vizsgálja a késő bizánci episztolográfia válogatott alkotásaiban. Módszertani szempontból a disszertáció a forrásszövegek close reading elemzése, vagyis azokat a szöveg kontextusában értelmező analízise mellett két módszertani megközelítést alkalmaz. Ezek egyike a Fredrik Barth és Thomas Hylland Eriksen által az etnicitás vizsgálatára kidolgozott kulturális antropológiai metodológia, míg a másik módszertani alappillér a bizánci episztolográfia irodalomtudományi szempontú megközelítése. Az értekezés végkövetkeztetései négy pontban összegezhetőek. Először is, a latinokra vonatkozó általánosító nézetek széles köre jelenik meg a vizsgált levelekben. Ezek a nézetek változatos kategóriákba rendezhetőek, a hétköznapi erkölcstől a fegyveres konfliktusok köréig. Másodszor, a levelekben feltűnő témák erős átfedést mutatnak a latinokkal kapcsolatban a bizánci irodalomban általában tárgyalt nézetekkel. Határozott többségben vannak azok a vallási és szekuláris kérdések, amelyek a latinok és bizánciak közötti különbségtétel kulcselemei voltak a korszakban, így például a Szentlélek származásáról vallott nézetek vagy a civilizációs szintben felfedezni vélt különbségek. A harmadik eredmény a szerzőknek az általuk bemutatott témákkal szembeni attitűdjeire vonatkozik. A forrásokban megjelenő értékítéletek köre a merev elítéléstől a lelkes méltatásig terjed, s mind a negatív, mind a pozitív vélemények a spektrum szélei felé tendálnak, míg a visszafogott értékelések száma viszonylag csekély. Emellett összességében a negatív vélemények vannak többségben. Végezetül, a negyedik eredmény az előbb említett attitűdök kontextusát érinti. A nyugatiak reprezentációi a levelekben nagyon erős korrelációt mutatnak az egyes szerzők róluk vallott általános nézeteivel, vagyis a latinellenes szerzők túlnyomórészt latinellenes nézeteket fogalmaznak meg leveleikben, míg a latinbarát szerzők megnyilvánulásai elsöprő többségükben kedvezően mutatják be a nyugatiakat.
Brunetto Latini arcai

Published: January 2021

A doktori disszertáció nemcsak a magyar, hanem az olasz kutatásban is meglévő hiányt igyekszik pótolni Brunetto Latini Il Tesoretto című allegorikus-didaktikus költeményének elemzésével. A dolgozat célja egyrészt az, hogy megismertesse az olvasóval a Magyarországon szinte ismeretlen Brunetto Latinit, életútjának legfontosabb állomásain, valamint életművén keresztül. Az értekezés másik célkitűzése, hogy az eddigi szakirodalmi eredményekre támaszkodva teljes képet adjon Latini forrásairól és lehetséges modelljeiről, immár több saját elemzési szemponttal is gazdagítva a kérdéskört. Továbbá arra is törekszik, hogy ezen elemek átvételét, a források kezelését és átstrukturálását vizsgálva bizonyítsa, hogy Latininek azon ambíciója is világosan kirajzolódik a költeményben, hogy meghaladja, túllépje modelljeit. Végül számos szempont alapján történik meg az Il Tesoretto interpretációja, elődei műveihez és a korszak irányzataihoz kapcsolódó értelmezése. Az elemzés során egyaránt szerepet játszanak az eszme- és politikatörténeti megfontolások, a műfajtörténeti és irodalomtörténeti hagyományba való beillesztés, valamint (részben) a nyelvi és stilisztikai elemzések is. Az értekezés legfőbb célja tehát, hogy a költemény forráskezelésének és szerkezeti elemeinek elkülönítése és rendszerbe illesztése, majd saját szempontú, részletes elemzése segítségével átfogó képet adjon az Il Tesorettóról és arról, mi lehetett Latini célja annak megírásával.

This study aims to determine whether there is work burnout felt by librarians at the Library Directorate of the Islamic University of Indonesia (UII). If the results of this study show symptoms of work burnout, it will be measured to what extent the work saturation is. Then, this research will also show a picture of job satisfaction of the librarians of the Directorate of Library UII. This research uses a quantitative approach with descriptive methods. This research is a population study that will make all librarians at the Directorate of Library UII as research subjects. The results showed that the average score of work saturation (burnout) based on the MBI for librarians in the Directorate of Library UII was 5.15. The average score of job satisfaction experienced by librarians in the UII Library Directorate is 30.48. There is a relationship between job burnout (burnout) and librarian job satisfaction in the Directorate of Library UII which shows a value of -0.489. This means that in this study the librarian burnout level was rather low followed by job satisfaction which was at the level of satisfaction.
Development of learning material to complement pain education of physiotherapists in Indian universities: A synthesis of an action research study
Authors: Mathew Jerin , Rashid M , Shirsath P , Raja K
Published: January 2021

Background and purpose: It is necessary to bring the current understanding of pain to undergraduate, postgraduate, and academic faculty of physiotherapy in all the universities and independent institutions in India. A minimum of approximately 15,000 students are graduated every year from various physiotherapy institutions in India. More than 20,000 physiotherapists teach or practice in various institutions, hospitals, and universities. The current pain curriculum for physiotherapy education is outdated and scanty. Physiotherapists are first-line managers of pain and it is important to understand the current advances in pain management to effect competent practice. Methods: An action research methodological concept (three phases) has been adapted to identify the missing areas of pain science from the physiotherapy curricula of universities of India (n=30). Instructional Digital Versatile Discs (DVD) was developed in these areas by experts through consensus methods. The reach of the study was evaluated through Google forms and email responses received from the participating institutions. Results: Pain lectures (22 hours) were recorded and four DVDs were commercially produced and duplicated. The DVDs were sent to all the universities and individual institutions (n=469) by post and recommended that they incorporate the information into the undergraduate and postgraduate curricula. The lecture series was also made available online via the institutional library depository system. Conclusion: This project has created a snowball effect by imparting current understanding and knowledge in young therapists and teaching faculty as the lectures are available on the website of the participating institution. Cultural and other characteristics are similar across the countries of South Asia (India, Pakistan, Sri Lanka, Nepal, Bhutan, Bangladesh, Maldives, and Myanmar) and all of these countries use English as the medium of higher education. Hence a regional impact is also anticipated

Relative Price Levels in Cities and Regions: A Comparative Aspect
Authors:   Economic Research Institute FEB RAS, Domnich Yegor
Published: January 2021

The study discusses the analytical value of the cost-of-living index as a measure of the relative price level in the Russian economic space. It is established that the estimates of the cost-of-living index obtained by Rosstat are heterogeneous across the country in terms of territorial coverage and representativeness of data by region. The worst representation of the indicator is typical for the most backward regions of late development and the most developed regions with an evenly distributed urban population. The thesis about the exclusivity of the cost-of-living index as a measure of the relative price level in comparison with other spatial indices is disputed

Methane (CH4) emissions to the atmosphere from the oil and gas sector in Romania remain highly uncertain despite their relevance for the European Union’s goals to reduce greenhouse gas emissions. Measurements of CH4 isotopic composition can be used for source attribution, which is important in top-down studies of emissions from extended areas. We performed isotope measurements of CH4 in atmospheric air samples collected from an aircraft (24 locations) and ground vehicles (83 locations), around oil and gas production sites in Romania, with focus on the Romanian Plain. Ethane to methane ratios were derived at 412 locations of the same fossil fuel activity clusters. The resulting isotopic signals (δ13C and δ2H in CH4) covered a wide range of values, indicating mainly thermogenic gas sources (associated with oil production) in the Romanian Plain, mostly in Prahova county (δ13C from –67.8 ± 1.2 to –22.4 ± 0.04 ‰ Vienna Pee Dee Belmnite; δ2H from –255 ± 12 to –138 ± 11 ‰ Vienna Standard Mean Ocean Water) but also the presence of some natural gas reservoirs of microbial origin in Dolj, Ialomiţa, Prahova, and likely Teleorman counties. The classification based on ethane data was generally in agreement with the one based on CH4 isotopic composition and confirmed the interpretation of the gas origin. In several cases, CH4 enhancements sampled from the aircraft could directly be linked to the underlying production clusters using wind data. The combination of δ13C and δ2H signals in these samples confirms that the oil and gas production sector is the main source of CH4 emissions in the target areas. We found that average CH4 isotopic signatures in Romania are significantly lower than commonly used values for the global fossil fuel emissions. Our results emphasize the importance of regional variations in CH4 isotopes, with implications for global inversion modeling studies.

Modelo cinemático inverso para robot móvil diferencial Pioneer utilizando software Coppelia.
Authors: Alonso Pineda González , Diego Alejandro Sanchez Orozco , José Guillermo Guarnizo Marín
Published: January 2021

En el presente video se describe el diseño de una trayectoria circular de un Robot Pioneer 3 simulado en el entorno de desarrollo integrado CoppeliaSim, a partir del modelo cinemático inverso para robots móviles diferenciales. El software CoppeliaSim es de frecuente uso en la ingeniería dada su facilidad para la descripción y comportamiento de robots sin necesidad de su presencia física, dando en su plataforma la posibilidad de simular robots reales para distintas aplicaciones tales como seguimiento y planeación de trayectorias, así como validar comportamiento programado con la posibilidad de transferirlos a un robot real [1] [2]. En robótica móvil el modelo cinemático inverso permite describir el movimiento de un vehículo autónomo, buscando los valores de sus actuadores en función de una trayectoria deseada. Este modelo puede ser estudiado desde cualquier tipo de robots, siendo los de ruedas con tracción diferencial uno de los más estudiados por su sencillez, facilitando su uso en entornos cotidianos como bodegas, oficinas, casas entre otros [3]. El sistema de navegación implementado en este vídeo para el Robot Pioneer 3 se basa en el modelo cinemático inverso, que determina el modelo a partir de la configuración de los actuadores permitiendo al robot moverse libremente en un entorno, debido a que se trabaja sobre un robot de dos ruedas con tracción diferencial donde su direccionamiento y trayectoria vienen dados por la diferencia en las velocidades de las ruedas de manera independientes, dando al robot tracción y dirección [4]. Para este trabajo se obtuvieron parámetros físicos del robot como el tamaño de las ruedas y la distancia entre ellas, también se calculó la posición actual del vehículo en un sistema de coordenadas bidimensional. La trayectoria buscada es de carácter circular, siendo representada los puntos x,y en un círculo, con estos parámetros y conociendo las ecuaciones del modelo cinemático se puede obtener la velocidad lineal y angular del robot. La trayectoria fue programada utilizando Python.

El presente estudio evaluó la capacidad de asimilación de un vertimiento doméstico sobre una corriente hídrica aplicando el modelo Streeter y Phelps. Para esto se determinó la calidad del recurso mediante el Índice de Calidad de Agua-ICA propuesto por el IDEAM, además se evaluaron los procesos hidrodinámicos y su capacidad de depuración. Aplicando el modelo a un tramo especifico de la quebrada Mensulí, según el comportamiento de OD y DBO resultante, el vertimiento comienza su recuperación a 0,89 km, pero su completa asimilación se da a 17 km. Teniendo en cuenta que existen más vertimientos aguas abajo es importante que todos los usuarios de la corriente se comprometan a mitigar el impacto ambiental producido sobre el recurso. El estudio de caso permitió verificar que modelo de Streeter y Phelps es una herramienta válida para evaluar la asimilación de un vertimiento, así como también para la toma de decisiones en función de la recuperación del recurso hídrico, por lo que es una metodología que puede usarse en trámites ambientales.
Enfoques críticos en la comprensión de los problemas ambientales: la crisis del paradigma del desarrollo
Authors: Jairo Miguel Martinez Abello
Published: January 2021

Los conflictos ambientales en Colombia representan, casi como ninguno otro, un campo de cuestionamiento a los órdenes de la guerra y el capital. Este artículo de reflexión pretende señalar la urgencia de abordar su estudio desde la perspectiva de la crítica y la resistencia para comprender mejor las configuraciones históricas que explican las específicas formas que hoy adquieren, y como clave de la constitución de otras formas de concebir las relaciones de las comunidades con la naturaleza como apuesta creativa para la construcción de una paz estable y duradera en el actual contexto de posacuerdo. Teniendo como telón de fondo lo que Foucault denominara biopolítica, en la primera parte de este artículo se pone en evidencia cómo el carácter normalizador del capitalismo contemporáneo reduce a la naturaleza, lo vivo y lo no vivo, a ser un mero instrumento del progreso humano; en la segunda parte, se pone de presente el carácter disruptivo de los conflictos que emergen, en los terrenos no cooptados por la máquina del capital y de la guerra, alrededor de la comprensión, uso, apropiación y explotación de la naturaleza, lo vivo y lo no vivo; y en la tercera parte, a manera de conclusiones, se presenta cómo la perspectiva de lo crítico y lo resistente en el contexto de posacuerdo en Colombia reta al estudio de los conflictos ambientales como el escenario, por excelencia, de la interpelación a unas persistentes lógicas de acumulación y violencia.
Evaluación de la eficiencia para la captación de aguas lluvia y remoción de coliformes en un sistema urbano de drenaje sostenible empleando pavimentos porosos

En la actualidad, la gestión del agua lluvia en entornos urbanos se ha reconocido como uno de los temas de mayor interés, puesto que no es suficiente con las medidas adoptadas para evitar las inundaciones en las ciudades durante las épocas de lluvia intensa. Por otro lado, el efecto de la escorrentía generada sobre el medio ambiente transportadas aguas abajo, se encarga de arrastrar consigo varios contaminantes. Se han planteado estrategias de desarrollo sostenible y formas de aplicación en diferentes campos de la construcción, especialmente en el sector de la infraestructura vial con el fin de mantener un control sobre las aguas lluvias. Dentro de estas estrategias los sistemas de drenajes sostenibles son de gran importancia, ya que su aplicación trae consigo mejoras en la gestión del agua teniendo en cuenta que es un recurso indispensable para el desarrollo humano. Por lo tanto el presente proyecto presenta la capacidad de captación y remoción de coliformes de un sistema urbano de drenaje sostenible mediante el uso de pavimentos porosos. Para esto se realizaron dos montajes de pavimentos porosos empleando carbón activado y antracita como materiales filtrantes. Aguas lluvia sintéticas fueron empleadas para la evaluación de la remoción de coliformes totales . De ésta manera se obtuvieron muestras de la entrada, salida, 10, 20 y 30 minutos, de las que se lograron reducciones de hasta un 99.7% de coliformes en el montaje con antracita y 7% con el carbón activado. Finalmente, se econtró que la capacidad de retención de la antracita es proporcional a su proceso de colmatación, lo que indicaría la implementación de un protocolo de mantenimiento más estricto y adecuado que permita el uso de este material filtrante y que impida que se formen biopelículas al final de la capa, acelerando el proceso de colmatación del pavimento.

Los olores ofensivos son una problemática social ya que afecta la salud y calidad de vida de las personas cercanas a sitios de emisiones de estos olores. Dada esta situación, se han establecido normas regulatorias para el control y manejo de la emisión de gases en industrias, de manera que se hace importante cuantificar los gases emitidos en zonas de cercanas a poblaciones urbanas, para establecer posibles sistemas de control y cumplir la legislación. En este trabajo se cuantificaron, mediante un detector de gases portátil, H2S, NH3 y compuestos orgánicos volátiles (COVs) emitidos en la zona de pretratamiento de aguas residuales de la Planta de Tratamiento de Aguas Residuales (PTAR) El Salitre, en temporada seca y lluviosa. Se observó que el H2S fue el gas de mayor emisión y que la emisión de gases está relacionada directamente con las precipitaciones del día, de forma que en la temporada seca se observaron las mayores concentraciones de H2S, COVs y NH3. En la temporada seca también se observó una variabilidad diaria en la concentración de los gases, siendo más alta la concentración de gases en horas de la noche, periodo en el que se encontraron valores mayores a 100 ppm para H2S, 47 ppm de VOCs y 16 ppm de NH3. Estos resultados permitirán formular estrategias para el control y eliminación de gases que se adecuan a las condiciones de emisión de la PTAR.

Published: January 2021

Se evaluaron cinco extractos coagulantes naturales en solución salina de tallos de Hylocereus cf. trigonus (Cactus), exudado gomoso de Albizia saman (Campano), corteza de Guazuma ulmifolia (Guácimo) y corteza y semilla de Moringa oleífera (Moringa), en muestras de agua cruda tomadas del río Sinú, con niveles de turbidez inicial entre 56 y 300 unidades nefelométricas de turbidez (UNT). Con ensayos de jarras, se determinó las eficiencias de remoción de turbidez, en función del porcentaje de actividad coagulante, para dosis aplicadas entre 5 mg/L a 200 mg/L. Las eficiencias de remoción variaron de 40% (con turbidez menores a 100 UNT) hasta 90% (con turbidez inicial mayor a 150 UNT) para dosis óptimas de 10 mg/L a 40 mg/L de extractos de tallos de H. cf. trigonus, exudado gomoso de A. saman, y cortezas de G. ulmifolia y de M. oleífera. El extracto de mayor eficiencia fue el obtenido de la semilla de M. oleífera, siendo más efectivo con turbidez mayor a 150 UNT, con eficiencias del 98%.
