There are numerous of clustering techniques that have been exploited by researchers in many applications such in medical application, image processing application as well as in high voltage application. Clustering technique is an unsupervised learning algorithm used to identify group structure in a set of data that contain different characteristics. Nowadays, within the latest HV insulation system, there are more than one dielectric media, which contribute to multiple source of partial discharge (PD). Therefore, data identification for PD is significantly vital to discover the kinds of faults that inducing discharges in a HV insulation system. Nevertheless, it is critical that the methodology used for further investigation such as phase-resolved partial discharge (PRPD) analysis is capable of producing a sufficient separation between the clustered data. An experiment was performed to generate a pair of PD sources simultaneously within a winding of the HV transformer. The PD pulses were collected from two measuring points measured by two wideband radio frequency current transformers (RFCTs) at the bushing tap-point to earth (BT) and the neutral to earth-point (NE).The performance oft-Distributed Stochastic Neighbour Embedding (t-SNE), Principle Component Analysis (PCA) and time-frequency mapping based on sparsity roughness at distinguishing multiple PD sources is determined and presented.

The photovoltaic (PV) panel performances are dependent upon many factors. A study was executed to ascertain the effect of a V-Trough Concentrator (VTC) to be engaged on a PV Panel in this research where the performance of PV panels are compared at different surface temperatures both back and front. The experiment was conducted using two similar rated monocrystalline PV panels. One of the PV panels was installed with a VTC while the other is without the VTC that served as Control for benchmark purposes. The optimum VTC selected is a 60° VTC. Both PV systems were built with a lower supporting mechanism and were placed to operate under similar operating and weather situations, while the PV panel surface temperature both front surface and back surface, Open Circuit Voltage (Voc), as well as Short-Circuit Current (Isc) readings are being recorded down at specific time. The theoretical output is determined and compared. This paper ends with a presentation of the results obtained in a study on the PV panel surfaces temperature in relation to its performance by PV system using a 60o VTC.

Reactive extraction of levulinic acid using trin- octylamine (TOA) in 1-hexanol was investigated by physical and chemical extractions from aqueous solution at room temperature. Using the equilibrium data, the distribution coefficient (KD), extraction efficiency (E%), loading ratio (Z), stoichiometric loading factor (ZS) and modified separation factor (Sf) are evaluated. It was observed that chemical extraction provided a better yield than physical extraction. A maximum KD was obtained as 10.715 using 40% TOA (0.9059 mol/L) while 91.46% of the levulinic acid was extracted. By increasing the initial concentration of levulinic acid resulted in a decrease of KD and E%. The KD and E% increased by increasing the TOA concentration from 10 to 40% (0.2264 mol/L to 0.9059 mol/L).

Steel slag is a byproduct and waste material produced in steel industries. This kind of solid waste material creates disposal problem and environmental effects. Demand of concrete and consequently the aggregate demand was rising fatly. Hence, it is necessary to find other substitute for aggregates. Experiments were conducted to determine the compressive strength, Young’s modulus, flexural strength, Poisson’s ratio, Abrasion resistance and impact strength of concrete with different percentage of steel slag aggregate. Pavement design is carried as per IRC:58-2002.The results specify that with the rise in percentage of steel slag aggregate the strength decreases when compared to the normal concrete, but at the same instant the strength satisfied the grade (M40) concrete up to 50% replacement of steel slag. Increase of steel slag from 10% to 100% shows improvement in Impact strength as compared with normal concrete. However use of this kind of materials in road construction, will reduce the cost of construction, leads to alternate the conventional material and makes the environment pollution free.

We should be prepared to smallpox re-emergence
Authors: Shchelkunov S. N. , Shchelkunova G. A.
Published: January 2020

The review contains a brief analysis of the results of investigations conducted during 40 years after smallpox eradication and directed to study genomic organization and evolution of variola virus (VARV) and development of modern diagnostics, vaccines and chemotherapies of smallpox and other zoonotic orthopoxviral infections of humans. Taking into account that smallpox vaccination in several cases had adverse side effects, WHO recommended ceasing this vaccination after 1980 in all countries of the world. The result of this decision is that the mankind lost the collective immunity not only to smallpox, but also to other zoonotic orthopoxvirus infections. The ever more frequently recorded human cases of zoonotic orthopoxvirus infections force to renew consideration of the problem of possible smallpox reemergence resulting from natural evolution of these viruses. Analysis of the available archive data on smallpox epidemics, the history of ancient civilizations, and the newest data on the evolutionary relationship of orthopoxviruses has allowed us to hypothesize that VARV could have repeatedly reemerged via evolutionary changes in a zoonotic ancestor virus and then disappeared because of insufficient population size of isolated ancient civilizations. Only the historically last smallpox pandemic continued for a long time and was contained and stopped in the 20th century thanks to the joint efforts of medics and scientists from many countries under the aegis of WHO. Thus, there is no fundamental prohibition on potential reemergence of smallpox or a similar human disease in future in the course of natural evolution of the currently existing zoonotic orthopoxviruses. Correspondingly, it is of the utmost importance to develop and widely adopt state-of-the-art methods for efficient and rapid species-specific diagnosis of all orthopoxvirus species pathogenic for humans, VARV included. It is also most important to develop new safe methods for prevention and therapy of human orthopoxvirus infections.

Introduction. There are natural foci of Crimean-Congo hemorrhagic fever (CCHF) that vectored by Hyalomma marginatum ticks in Volga river delta (Astrakhan region, South of Russia). The circulation of Dhori virus (DHOV) (Thogotovirus: Orthomyxoviridae) has been also shown here. We hypothesized that other tick-borne arboviruses are also likely to circulate in the region. In particular, Bhanja virus (Phlebovirus: Phenuiviridae), Wad Medani virus (Orbivirus: Reoviridae), and Tamdy virus (Orthonairovirus: Nairoviridae), which were found to circulate in neighboring regions and are vectored by Haemaphysalis spp., Dermacenter spp., and Hyalomma spp. ticks.Goals and objectives. The aim of the study was to examine ixodid ticks in Volga river delta for the presence of CCHFV, DHOV, Bhanja virus, Wad Medani virus, and Tamdy virus.Material and methods. Ticks were collected in Volga river delta in 2017. We used molecular genetic methods for the detection and analysis of nucleic acids (PCR, sequencing, phylogenetic analysis).Results. We detect CCHFV and DHOV RNA in H. marginatum ticks. The rate of infected H. marginatum ticks was 1.98% for CCHFV and 0.4% for DHOV. The results of genetic analysis showed that found DHOV strains are almost identical (99- 100% in the M gene) and forms a separate genetic lineage alongside of Batken virus from Central Asia. At the same time, Bhanja virus, Wad Medani virus, and Tamdy virus were not found in ticks, collected in this region.Conclusions. DHOV is circulating in the natural foci of CCHF in the Volga river delta. The ratio of infection of H. marginatum with CCHFV and DHOV was determined for the first time.

Introduction. The reasons of late diagnosis of nasopharyngeal carcinoma (NPC) are the long asymptomatic course of the pathological process, the anatomical structure of the nasopharynx, often small, visually and endoscopically undetectable tumor and other factors. It is proved that the Epstein-Barr virus (EBV) is an etiological agent in the most common undifferentiated non-keratinizing histological type of NPC (uNPC).The aim of the work was to assess the significance of diagnostic markers of EBV (titers of humoral antibodies to the virus and the concentration of viral DNA in plasma) for the diagnosis of uNPC in a group of patients with metastatic lesions of the cervical lymph nodes without an identified localization of the primary tumor focus.Material and methods. The material for the study was blood plasma of 83 patients with metastatic lesions of the cervical lymph nodes and not established localization of the primary tumor. Plasma samples were tested for the anti-EBV IgG and IgA antibody content and titers and the concentration of viral DNA.Results and discussion. The data obtained indicate that the parallel testing of blood plasma for EBV-specific antibodies and viral load is a useful tool for preliminary screening of uNPC patients. The final diagnosis is confirmed by the data of subsequent morphological and instrumental studies. Several examples also show that the concentration of viral DNA in the blood plasma of patients with uNPC reflects the effect of the therapy and the prognosis of the disease: remission, stabilization of the tumor process, relapse or metastasis.Conclusion. Although the titers of virus-specific antibodies are found to reflect clinical manifestations of the disease less accurately than the plasma concentrations of viral DNA, serological markers are extremely important for the preliminary diagnostics of uNPC in cases of undetected primary tumor location. They are also useful for primary screening of this neoplasm among individuals at risk.

Introduction. The complexity of the treatment of herpetic keratoconjunctivitis is due to the severity of the disease, complications, the transition to chronic relapsing forms and the insufficient effectiveness of the drugs used, which leads to a steady increase in the number of patients.The aim of the study was to evaluate the therapeutic efficacy of the eye drug films «GlazAvir» in the experimental model of acute herpetic eye infection in rabbits.Research objectives: to study the specific activity of «GlazAvir» and compare the long-term indicators of the level of manifestation of individual clinical signs of keratoconjunctivitis.Material and methods. In the work we used rabbits of the Chinchilla breed, the herpes simplex virus type 1 and the eye drug films «GlazAvir». A model of ophthalmic herpetic infection was formed by infection of rabbits with virus-containing material of a pre-scarified eye cornea against the background of local anesthesia. Аnimals were treated with the drug «GlazAvir» - 1 application per day for 7 days. Animals were observed daily for 15 days, then every 3 days until the 25th day of observation. The effectiveness of the drug was evaluated at the peak of the development of the pathological process.Results and discussion. There was a decrease in mortality from 50 to 20%, and an increase in average life expectancy by 27.87%, compared with the control in animals treated with «GlazAvir». It was noted after activation of herpetic keratoconjunctivitis on the 2nd – 5th day, at the peak of the disease (6–9th day) a statistically significant decrease in the activity of the pathological process (p0.05) by rabbits treated with the «GlazAvir» ophthalmic drug films. The tendency to normalization by the rabbits treated with the «GlazAvir» preparation was observed until the 14th day.Conclusion. The data obtained indicate the pronounced effectiveness of the «GlazAvir» preparation in the treatment of experimental herpesvirus keratoconjunctivitis.

Published: January 2020

En el contexto Bogotano, existen múltiples instituciones dedicadas a la enseñanza del inglés, las cuales en su mayoría han particularizado modos de enseñanza de la lengua, sin embargo, también es muy común encontrarse con aquellas instituciones que optan por organizar sus contenidos alrededor de los temas incluidos dentro de los índices de un libro guía de inglés, dándole énfasis a la enseñanza de la gramática, la sintaxis y el vocabulario, advirtiéndose que esta tendencia no toma en cuenta la incidencia de la competencia socio intercultural en la enseñanza del inglés, como lengua extranjera. 

Los hechos referidos llevaron a analizar al investigador sobre la trascendía de evidenciar si la competencia socio cultural se incluye en las clases de inglés correspondiente a un programa técnico.

Esta investigación acudió a un enfoque cualitativo, con énfasis en la descripción e interpretación de los datos por parte del investigador, con una perspectiva flexible, sistemática y rigurosa, tomando la opinión tanto de los aprendices como del profesor de inglés. Para recoger las muestras de análisis de este estudio se empleó el instrumento de la entrevista aplicada a la población en cuestión.

Los hallazgos sugieren que se contempla la competencia socio intercultural en las clases de inglés, pero no con la debida importancia para contribuir de manera eficaz en la adquisición de la lengua extranjera.

Esta investigación concluye que el aprendizaje de una lengua, en un mundo caracterizado por la globalización, debe partir de la comprensión de los aspectos culturales asociados a la apropiación de una lengua.

This study examined the influence of capital structure and interest rate as determinants of profitability and efficiency of universal and commercial banks in the Philippines. The researcher uses equity capital and debt capital to measure capital structure, and return on asset, and return on equity as a measure of efficiency and profitability respectively. The method used to summarize the relationship of these banks was Multivariate Regression Analysis. The results shows that capital and interest rate have significant effect to return on asset and return on equity by showing a p-value of less than five percent in the regression analysis. Capital structure in terms of debt capital has negative effect while equity capital shows positive impact to ROA and ROE. Moreover, interest rate also shows a negative effect to the performance of banks. Thus, the paper recommends universal and commercial banks should strengthen their efforts to depend on internally generated funds as their source of finance.

La afinación temperada de instrumentos autóctonos de las músicas tradicionales colombianas: problemáticas relacionales entre la tradición y la música comercial
Authors: Moreno Espinal Jamir Mauricio , Restrepo Rueda John Manuel
Published: January 2020

Este artículo es producto del proyecto de investigación “Banco ampliado de sonidos digitales de los instrumentos musicales del folclor colombiano – P142113”, realizado por la Escuela Superior de Artes Débora Arango y el Instituto Tecnológico Metropolitano. Cuyo objetivo esencial fue la realización de un banco de sonidos virtuales de instrumentos y ritmos de las músicas tradicionales colombianas, el cual puede ser utilizado en diferentes plataformas digitales de producción musical por músicos y productores, en la generación de contenidos musicales. En este proyecto se registraron las cualidades técnicas y sonoras de la Flauta de Millo, las Gaitas, la Marimba de Chonta, el Acordeón, la Bandola y el Tiple. Para tal fin se utilizaron las técnicas más avanzadas en el proceso de captura. Como resultado se obtuvieron unos bancos de sonidos de alta calidad que pueden ser utilizados en cualquier software de producción musical. Al concluir la investigación, se encontró una ligera diferencia de afinación, en algunos instrumentos, respecto a los parámetros de afinación de la música occidental centroeuropea. Situación que genera cierta incompatibilidad con el temperamento de la música comercial. Este artículo pretende incentivar la discusión sobre las problemáticas relacionales que acontecen con estos instrumentos y su inserción en la música comercial.
Mirada, Territorio, Cuerpo y Palabra: a propósito de lo que se cuenta sin contar
Authors: Osorio Yoni Alexander
Published: January 2020

El texto pretende hacer una reflexión sobre la mirada, que, cuando se cultiva, puede visibilizar historias ocultas en los territorios con el objeto de crear memoria, identidad y conciencia de sí. Es una exploración por las historias ocultas tras lo evidente a los ojos; plantea el ejercicio de ver más allá de lo inmediato a los sentidos para reconocer que es más importante aquello no contado, lo que se dice sin decir, y lo que está detrás de cada acontecimiento, que encierra toda una memoria, sobre el territorio, el cuerpo y la identidad.
