legitimidad del poder
Authors: Hernández Toledo Sebastián 
Published: April 2021

Este artículo analiza las diferentes características, nociones y definiciones del concepto de democracia en Chile entre 1925 y 1948. A partir de folletería, libros y prensa editados en este periodo se examina la trayectoria y transformación de esta idea. La hipótesis sostiene que, desde la promulgación de la Constitución de 1925 hasta la publicación de la Ley de Defensa Permanente a la Democracia en 1948, el concepto democracia como mecanismo legitimador del poder político experimentó cuestionamientos y redefiniciones en sus dimensiones y particularidades que dependieron de las aspiraciones de diferentes actores políticos. El artículo identifica cuatro momentos y en cada uno de ellos se aborda un grupo político específico sobre el cual se analizan los usos de la noción de democracia. Al hacerlo, se pretende mostrar parte del conflicto político de la época y el zigzagueante uso del concepto democracia en la disputa por el poder.

Authors: Laksono Stefanus Ivan , Aritonang Y. M. Kinley , Lesmono Julius Dharma 
Published: April 2021

The Location Routing Problem with Roaming Delivery Locations (LRPRDL) is a model that represents company activities in delivering products to final customers. Direct delivery to final customers has increased significantly over the growth of e-commerce in the world. E-commerce or business-to-customer companies are urged to increase their last-mile distribution efficiency to survive in the global competition. For that purpose, the LRPRDL model was proposed to increase the efficiency of the company’s last-mile distribution. The model aims to minimize the sum of open depots and transportation costs by determining the number and location of depots and the shipping routes. The LRPRDL was implemented in an instance with four depot candidates, 15 customers, and six vehicles. The instance was solved to the optimality by using a public solver Gurobi. Furthermore, this research conducted a sensitivity analysis on the open depots and fuel costs, customer demand, and radius. The study indicated that customer’s demand and radius have a significant impact on the purchase decision.

Published: April 2021

Le tecniche che vengono impiegate per affrontare una valutazione di
impatto ambientale sono varie, esistono alcune tecniche di più recente
utilizzo, altre che si sono consolidate con il tempo. Nel seguente
studio, infatti, vengono riprese delle tecniche ben lontane tra loro nel
tempo, nello specifico la matrice di Leopold (sviluppata nel 1971) e il
metodo KFCM. La matrice di Leopold viene utilizzata per la valutazione
di impatto ambientale relativo al progetto di un parco eolico, in cui
vengono affrontati sia gli impatti positivi e che negativi dei diversi
comparti. Segue a questo caso studio un metodo più innovativo, per
migliorare attraverso l’utilizzo dell’ANN (Artificial Neural Network),
quella che è l’analisi decisionale, riducendo la soggettività,
attraverso l’impiego del KFCM (Metodo Kernel Fuzzy Clusteryng
Means Algoritm) e della rete neurale BP (Back propagation) , in modo
tale da standardizzare il processo. L’obiettivo di questo metodo è
quello di analizzare i potenziali impatti dell’opera, in modo tale da
generare una soluzione di progettazione ottimizzata per ridurre i
potenziali impatti ambientali.

Coronaviruses can cause damage to various parts of the respiratory system, gastrointestinal tract, and other organs and systems.The aim of the study: to monitor the circulation of seasonal coronaviruses in hospitalized children in the pre-pandemic period.Materials and methods: real-time multiplex PCR was used to test samples of nasopharyngeal mucus from 2188 patients aged 1 monthto 17 years, hospitalized with acute respiratory infection in 2014—2018. The results are presented with the indication of the fractions (%) and the calculation of the 95% confidence interval according to Klopper-Pearson. The differences between the groups were evaluated using the Pearson χ2 test. The differences in the groups were considered statistically significant at the level of the criterion p< 0.05.Results: monitoring of the circulation of pathogens of acute respiratory viral infection (ARVI) during 5 epidemic seasons showed that the appearance of a new subtype of coronavirus in 2019 was preceded by a gradual displacement of influenza, RS-and bocavirus infections from the circulation due to a statistically significant increase in the proportion of seasonal coronaviruses from 3.6% in 2014—2015 to 10.8% in the prepandemic season 2018—2019 (p= 0.007). The circulation of seasonal coronaviruses had a distinct seasonality (november-april)with the peak of registration in february (28.4%) and march (36.7%). Seasonal coronaviruses were detected in 7.3% of hospitalized children with ARVI, with a predominance in the age groups under 2 years (58.2%) and 3—6 years (25.4%). Hospitalization was more often required for patients with lower respiratory tract lesions (58.2%), a fifth of which was pneumonia (21.8%). In most children, ARVI caused by coronaviruses occurred as a monoinfection (79.9%), combined infection with other pathogens was observed in 20.1% of cases with fluctuations from 18.2% to 28.6% in different epidemic seasons. Viral associations are most common in young children (85.2%).

Authors: Czupryński A. , Mele C. 
Published: April 2021

Abstract
The article presents the results of the preliminary research of tribological properties of flame sprayed nickel and aluminum coatings reinforced with carbon nanotubes made on the structural steel S235J0 substrate. The carbon material – carbon nanotubes Nanocyl NC 7000 (0.5 wt.% and 1 wt.%) was used for structural reinforcement. The properties evaluation was made by the use of optical microscopy, scanning electron microscopy, Raman spectroscopy, microhardness measurements, and by means of abrasion and erosion resistance laboratory tests. The obtained results were compared with pure nickel powder coatings 2N5 (Ni 99.5%) and with pure aluminum powder coatings (EN AW 1000 series). It was proved that the flame spraying of nickel and aluminum coatings reinforced with particles carbonaceous material can be an effective alternative for other more advanced surfacing technology. The preliminary test results will be successively extended by further experiments to contribute in the near future to develop innovative technologies, that can be implemented in the aviation industry and the automotive. The presented research is a continuation of the work previously published.

Published: April 2021

Abstract
The aim of the study was to determine the impact of different feed rations (0.5, 0.8, 1.1% fish biomass) on the rearing parameters of pikeperch, Sander lucioperca (L.), reared in a recirculating aquaculture system. The study comprised two experiments. In the first, the material used had been sorted by a mean body weight of 35.5 g, while in the second the pikeperch were divided into three size classes: smallest individuals (class S) with a mean body weight of 59.5 g, medium-sized individuals (class M) with a mean weight of 69.3 g, and largest individuals (class L) with a mean body weight of 84.8 g. The experiments ran for 42 days. At the conclusion of the experiments, the highest body weight and length, daily growth rate, and specific growth rate were attained by the group of fish fed the ration of 1.1% of the fish biomass in both experiments I and II. The feed conversion ratio was also the lowest in this feed ration group, and it differed significantly statistically among the experimental groups (P < 0.05). The feed ration of 0.5% of the fish biomass was only sufficient to maintain vital functions, but it contributed only slightly to growth. The different feed rations did not have a significant impact on the final value of the body weight coefficient of variation of the pikeperch reared in the two experiments. The results of the experiment also indicated that pikeperch is a species with weak stock hierarchy and domination structure.

Published: April 2021

Abstract
The aim of this study was to evaluate the effects of variety and extraction system on the physico-chemical and sensorial characteristics of olive oils produced from three dominant varieties of Algeria (Azeradj, Chemlal and Sigoise). The olive oils were extracted by three different processes (pressure system, two-phase centrifugation and traditional process). Physicochemical parameters including free acidity, peroxide value, absorbance in ultra violet (K232, K270, ΔK) and sensory evaluation were studied. The results show that free acidity, peroxyde value and K270 were influenced by the extraction system and variety. Olive oils obtained from the two phases centrifugation and Chemlal cultivar were characterized by higher oxidative stability. Sensory characteristics of olive oils were mainly influenced by the variety and extraction system. Olive oils obtained from the two phases centrifugation, traditional cold process and Sigoise variety were characterized by the lower mean values of negative attributes.

Published: April 2021

Abstract
This study aims to reveal the antioxidant activity and phenolic ingredients of yogurts added with black cumin (Nigella sativa L.) honey. Therefore, this study aimed to produce healthy food made with black cumin honey with increased total phenolic contents and antioxidant activity. The effect of varying degrees of black cumin honey addition (0, 2.5%, 5%, 10%, 15%) on the antioxidant activity and total phenolic contents of yogurt were examined for 28 days. The antioxidant activity was found between 14.33 and 17.41 mM TE. Total phenolic compounds were between 202.50 and 1415.00 mg GAE/kg. Some important differences were determined between yogurts with black cumin honey and the control with respect to phenolic contents during storage (p < 0.05). The results of study reveal that the augmentation of fortification rate increased the total phenolic characteristic and antioxidant activity of yogurt with black cumin honey. Significantly, these outcomes indicate that yogurt with black cumin honey have a high level of polyphenols and could be consumed as bioactive composition.

Published: April 2021

Abstract
The menace of corrosion of steel in industries has been widely acknowledged. Analysis of oil pipeline failures in oil and gas industries in the Niger Delta area of Nigeria showed corrosion as one of the major causes of failure. Eco-friendly, cheap and renewable materials such as plant extracts have been investigated as alternative to the use of expensive synthetic chemicals which are often hazardous. In this study inhibitive properties of ethanol extracts of Ficus polita and Ficus platyphylla leaves as eco-friendly inhibitors of mild steel in 2 M sulfuric acid solution were investigated by weight loss method at temperatures of 301, 305, 309 and 313 K. The study has shown that both plant extracts inhibited the corrosion of mild steel in the acid medium. The inhibition efficiency (IE) and surface coverage (θ) for both extracts increased with increase in concentration and temperature. This trend is suggestive of chemical adsorption. However, the leaf extract of Ficus polita showed higher IE compared to F. platyphylla. Thermodynamic parameters and apparent activation energy obtained from the studies revealed the inhibition by both plant extracts to be spontaneous, exothermic and chemisorptive, while the adsorption mechanism of both plant extracts on the steel surface aligned with the Freundlich isotherm model, F. polita fits well to Temkin and Adejo-Ekwenchi isotherm models in addition.

Published: April 2021

AbstractEfficient resource allocation through Virtual machine placement in a cloud datacenter is an ever-growing demand. Different Virtual Machine optimization techniques are constructed for different optimization problems. Particle Swam Optimization (PSO) Algorithm is one of the optimization techniques to solve the multidimensional virtual machine placement problem. In the algorithm being proposed we use the combination of Modified First Fit Decreasing Algorithm (MFFD) with Particle Swarm Optimization Algorithm, used to solve the best Virtual Machine packing in active Physical Machines to reduce energy consumption; we first screen all Physical Machines for possible accommodation in each Physical Machine and then the Modified Particle Swam Optimization (MPSO) Algorithm is used to get the best fit solution.. In our paper, we discuss how to improve the efficiency of Particle Swarm Intelligence by adapting the efficient mechanism being proposed. The obtained result shows that the proposed algorithm provides an optimized solution compared to the existing algorithms.

Published: April 2021

Abstract
Following an integrated data analytics framework that includes descriptive analysis and multiple automatic content analysis, we examined 265 projects that have been funded by the National Science Foundation (NSF) under the Smart and Connected Health (SCH) program. Our analysis discovered certain characteristics of these projects, including the distribution of the funds over years, the leading organizations in SCH, and the multidisciplinary nature of these projects. We also conducted content analysis on project titles and automatic analysis on the abstracts of the projects, including term frequency/word cloud analysis, clustering analysis, and topic modeling using Biterm method. Our analysis found that five main research areas were explored in these projects: system or platform development, modeling or algorithmic development for various purposes, designing smart health devices, clinical data collection and application, and education and academic activities of SCH. Together we obtained a comparatively fair understanding of these projects and demonstrated how different analytic approaches could complement each other. Future research will focus on the impact of these projects through an analysis of their publications and citations.
