Degradation of organic pollutant in restaurant wastewater using the homogenous catalysis with Mn(II) and EDTA
Authors: Nguyen Ngoc Tue  , Nguyen Duc Trung  
Published: October 2021

It can be seen that the objects of wastewater that need to be treated are quite diverse in types and complex in terms of reaction mechanisms. The methods mainly focus on the treatment of toxic organic compounds, especially phenols or plant protection agents in industrial wastewater, paper industry, food production, textile industry, printing industry... The activation of H2O2 and O2 by complexes of transitional metal ions and suitable ligands creates oxidizing agents and ecologically healthy products. The intermediate substances arising in the activation process such as free radicals OH., O2., HO2., ... can oxidize many compounds, especially the ability to attack the aroma of organic pollutants. In this paper, the results of research on treating organic pollution in restaurant wastewater with H2O2 are presented as a catalyst of complexes between Mn2+ ions and EDTA. The conditions including pH, EDTA/Mn2+, the concentration of H2O2, Mn2+ were investigated to obtain the optimum conditions for improving COD treatment efficiency. This work proposes a method based on formation of the Mn(II)-EDTA complex, b=1; with the optimal conditions of other factors as following [H2O2]0 = 0,75.10-3 mol/L; [Mn(EDTA)]2- = 33,33 mol/L, pH=10.5; t = 15 minutes. The initial COD of 1025 mg/L decreased to 135 mg/L after the proposed procedure. The results provide solutions of homogeneous complex catalysts for domestic/restaurant and industrial wastewater treatment at room temperature and atmosphere.

Published: October 2021

CuMnOx spinel catalyst, prepared by the sol-gel method, and characterized by modern techniques such as XRD, BET, H2-TPR, EPR, were used to oxide toluene in the temperature range from 150oC to 400oC . Among, the investigated catalysts as MnO2, CuO, and CuMnOx, the CuMnOx showed the highest catalytic activity. It converted 100% toluene to CO2 at 250oC in excessed oxygen conditions. The higher catalytic performance of CuMnOx than MnO2, CuO because of its higher specific surface area and its lower reduction temperature. The results also implied that the interaction between Cu and Mn could improve the reduction capacity of CuMnOx catalyst. In summary, the CuMnOx catalyst is a promising catalyst for toluene treatment.

Abstract. Recent simulation studies have provided evidence that a pulsating aurora (PsA) associated with high-energy electron precipitation is having a clear local impact on ozone chemistry in the polar middle mesosphere. However, it is not clear if the PsA is frequent enough to cause longer-term effects of measurable magnitude. There is also an open question of the relative contribution of PsA-related energetic electron precipitation (PsA EEP) to the total atmospheric forcing by solar energetic particle precipitation (EPP).
Here we investigate the PsA-EEP impact on stratospheric and mesospheric odd hydrogen, odd nitrogen, and ozone concentrations. We make use of the Whole Atmosphere Community Climate Model and recent understanding on PsA frequency, latitudinal and magnetic local time extent, and energy-flux spectra. Analysing an 18-month time period covering all seasons, we particularly look at PsA-EEP impacts at two polar observation stations located at opposite hemispheres: Tromsø in the Northern Hemisphere (NH) and Halley Research Station in the Southern Hemisphere (SH). We find that PsA EEP can have a measurable impact on ozone concentration above 30 km altitude, with ozone depletion by up to 8 % seen in winter periods due to PsA-EEP-driven NOx enhancement. We also find that direct mesospheric NOx production by high-energy electrons (E> 100 keV) accounts for about half of the PsA-EEP-driven upper stratospheric ozone depletion. A larger PsA-EEP impact is seen in the SH where the background dynamical variability is weaker than in the NH. Clearly indicated from our results, consideration of polar vortex dynamics is required to understand PsA-EEP impacts seen at ground observation stations, especially in the NH. We conclude that PsA-EEP has the potential to make an important contribution to the total EPP forcing; thus, it should be considered in atmospheric and climate simulations.

Ni amos ni siervos. Memoria obrera de Bogotá y Medellín (1910-1945)
Authors: Archila Neira Mauricio 
Published: October 2021

Desde 1985 iniciamos, con el apoyo del CINEP, una experiencia de recuperación de la historia de los trabajadores en varias ciudades colombianas. Teníamos la doble preocupación de: aportar académicamente al conocimiento del pasado de uno de los grupos sociales determinantes de la vida del país, y de colaborar en la reconstrucción de la memoria colectiva de los obreros de esas ciudades. Era un intento de hacer del oficio del historiador una práctica académica y democrática, acercando dos mundos temporalmente distanciados: el de los intelectuales y el de los obreros.En este número de Controversia Mauricio Archila ilustra las características de los grupos obreros de Medellín y Bogotá, ciudades con lejano pasado que sufren un desarrollo como centros comerciales internos y luego industriales. Medellín fue pionera en desarrollo industrial mientras a Bogotá la favoreció su posición como capital político-administrativa del país. Sus grupos obreros conformados por artesanos, ferroviarios y trabajadores de la construcción y más tarde de la industria manufacturera debieron dar una lucha lenta y poco notoria para diferenciarse de los pobres con los que las elites los querían asimilar. Las prácticas paternalistas y la introyección de la disciplina capitalista de trabajo, hacen de los núcleos obreros de estas dos ciudades, elementos aparentemente más dóciles y controlados por la patronal, especialmente en el caso de los textileros antioqueños. Los obreros deben, en consecuencia, construir una imagen diferente de sí mismos para lograr tener una identidad propia.Plabras Clave: Obreros, Memoria, Grupos sociales, Desarrollo insdustrial, Industria manufacturera, Bogotá, Medellin
Política de negociación con la guerrilla: Cambios de la administración Gaviria a la administración Samper
Authors: García Durán Mauricio 
Published: October 2021

En contravía con las expectativas que se suscitaron en los primeros meses de la administración Samper con relación a la posibilidad de avanzar en una nueva negociación con los grupos guerrilleros aun alzados en armas, los hechos parecen indicar otra dirección: de forma prematura y en gran medida condicionados por la actual coyuntura, las posibilidades para implementar una amplia política de paz en esta administración presidencial parecen haber llegado a su fin al completarse el primer año de gobierno. En ese sentido, estaríamos “condenados” a tres años más de guerra antes que un nuevo presidente pueda volver a abrir las puertas de la negociación.
Ante este sombrío panorama, surgen diversos interrogantes. ¿Qué pasó? ¿Por qué las iniciativas y esfuerzos adelantados no permitieron que despegara un nuevo proceso de negociación? ¿Cuáles fueron los obstáculos? ¿Estos responden más a las condiciones adversas de la crisis por la que pasa el gobierno en la actual coyuntura o son resultados de limitaciones en la formulación de la propuesta gubernamental?

De las voces oblicuas a la palabra pública. Una mirada a la esfera pública en contextos de violencia
Authors: Bonilla Vélez Jorge Ivan 
Published: October 2021

Este artículo elabora una aproximación a la esfera pública en contextos de violencia. Para estos examina las tensiones que existen entre el discurso público y el discurso oculto en situaciones características por el uso arbitrario del poder. Se sostiene que para pensar en procesos de verdad, justicia y reconstrucción de la memoria colectiva es necesario desatar las voces ocultas y las memorias atrapadas por el miedo y el silencio mediante formas de acción política y cultural que posibiliten la visibilidad en la esfera pública de las voces sujetos y asuntos que fueron obligados a mantener silencio.

From hidden voices to public speech. A look at the public sphere in violence contexts
This article attempts to develop an approach to public sphere in contexts of violence. For that it examines the tensions between public speech and hidden speech in situations characterized by the arbitrary use of power. It argues that to think about processes of truth, justice and reconstruction of collective memory it is necessary to unleash the hidden voices and memories trapped by fear and silence through forms of cultural and political action that allow visibility in the public sphere of voices, subjects and issues that were forced to remain silent.

Keywords: Communication, Politics, Public Sphere, Armed Conflict, Violence.
Los desempleados como sujetos de acción colectiva
Authors: Rúa Castañeda Sohely 
Published: October 2021

Ante la flexibilización laboral y la desregulación neolibral, la autora analiza uvas formas de trabajo no fabril en América Latina que recrean el mundo laboral y renuevan las identidades. Aunque su reflexión es de carácter teórico, la aplica a la situación actual de los piqueteros y cartoneros argentinos. Estudias también los repertorios de acción, las relaciones con el Estado y la dimensión política de las nuevas ciudadanías laborales que estos actores encarnan. Todo ello arroja nuevos sentidos en el mundo del trabajo que propenden por salidas al capitalismo neoliberal.
The Unemployed as Subjects of Collective Action
Faced labor flexibility and neoliberal deregulation, the author analyzes new forms of unmanufactured work in Latin America that recreate the world of labor, and renew identities. Although it is a theoretical reflection, the analysis is applied to the current situation of Argentine “piqueteros” in cardboard recycling industry. The article also studies the repertoires of action, the relations with the state, and the political dimension of the new labor citizenships that these actors incarnate. All this brings new meaning in the world of labor that promote alternatives to the neoliberal capitalism.

Geen coulance maar recht: de actieve raadsman bij het politieverhoor
De strafvorderlijke regulering van de verhoorbijstand in Nederland beperkt de advocaat in het op actieve wijze verlenen van bijstand tijdens het politieverhoor. Naar aanleiding van een uitspraak van het Hof van Discipline waarin een klacht over een actief optredende advocaat tijdens een politieverhoor ongegrond werd verklaard, wordt in dit artikel uiteengezet waarom de Nederlandse regeling niet (langer) verenigbaar is met de rechtspraak van het EHRM en Richtlijn 2013/48/EU.

Consiglieri
In de strijd tussen de verharde georganiseerde criminaliteit en de niets ontziende opsporing van strafbare feiten is de strafrechtadvocaat hoognodig voor de-escalatie en controle. Dat betekent niet dat geen kritiek mag worden geuit op de strafrechtadvocatuur. Het betekent wel dat er een breed gedragen verantwoordelijkheid bestaat voor iedereen met enige kennis en verstand van de strafrechtspleging om die advocaten niet gemakkelijk weg te zetten als maffiamaatjes. Strafrechtadvocaten verdienen bescherming in plaats van verdachtmakingen.

Digital investigation powers and privacy
With the Modernisation of the Code of Criminal Procedure, certain digital investigation powers will for the first time be given a specific statutory basis, such as the search of data carriers, open-source investigation and network searches. Nevertheless, considering the high degree of intrusiveness of such techniques, particularly with the right to privacy, it remains important to take note of the jurisprudence of the European Court of Human Rights, which continues to set minimum safeguards for the interference with private life. In this paper, we therefore conduct a brief overview of recent ECtHR case law concerning five types of digital investigation powers. We then consider the implications of this case law for the regulation of such powers in the draft Code of Criminal Procedure and for the Modernisation process more broadly.
Drug-like Properties and Fraction Lipophilicity Index as a combined metric
Authors: Tsantili-Kakoulidou Anna , Demopoulos Vassilis 
Published: October 2021

Fraction Lipophicity Index (FLI) has been developed as a composite drug-like metric combining logP and logD in a weighted manner. In the present study an extended data set confirmed the previously established drug-like FLI range 0-8 using two calculation systems for logP /logD assessment, the freeware MedChem Designer and ClogP. The dataset was split into two classes according to percentage of fraction absorbed (%FA) - class 1 including drugs with high to medium absorption levels and class 2 including poorly absorbed drugs. The FLI and FLI© (ClogP based FLI) drug-like range covers 93% and 90 % of class 1 drugs, respectively. The dependence of the degree of ionization to intrinsic lipophilicity within the FLI (FLI©) drug-like range as well as the inter-relation between the other Ro5 properties (Mw, HD, HA) was explored, so as to define drug-like / non drug-like combinations as a safer alternative to single properties for drug candidates’ prioritization. In this sense we propose a combined metric of Mw and number of polar atoms (Mw/NO) to account for both size and polarity. Setting the value 50 as cut off, a distinct differentiation between class 1 and class 2 drugs was obtained with Mw/NO>50 for more than 70% of class 1 drugs, while the opposite was observed for class 2 drugs.

Authors: Mandal Sanjit , Saha Gopal Chandra , Kumar Murmu Manoj 
Published: October 2021

Background: The environment and lifestyle of most children has led to the reduction of their motor activity, as they live in small spaces and lack the proper playing conditions. Coordination is about controlling all the body parts while doing different activities of children. It is about making and maintaining connections between the brain and the muscles that control movement of the children.
Objective: To compare the coordinative abilities between rural and urban male soccer players.
Methodology: A group of sixty (N=60) male soccer players aged between 13-18 years were randomly allowed for this study from different club of north 24 parganas district, West Bengal. They were further divided into two groups of 30 each (i.e., N1=30; rural players and N2=30; urban players). The purposive sampling technique was used to attain the objectives of the study. Orientation ability, Differentiation ability, Reaction ability, Balance ability and Rhythm ability were the Coordinative abilities selected for the study. The independent sample t- test statistical technique was used to analyzed the significant difference of coordinative abilities between rural and urban male soccer players and the level of significance was set at 0.05 levels.
Results: The results showed that there was significant difference between rural and urban male soccer players, in respect to their Coordinative abilities on the sub variables i.e. reaction ability, orientation ability and differentiation ability. However insignificant difference was found for rhythm ability.
Conclusions: It can be concluded that the rural male soccer players were better in Orientation ability, Differentiation ability, Reaction ability and Balance ability in comparison to urban male soccer players.
Detection and Antibiogram Profile of Enterococcus Species from Local Cheese Sample within Ikare and Akungba Akoko, Ondo State Nigeria
Authors: Charles Osunla Ayodeji 
Published: October 2021

Enterococci are part of the normal intestinal flora of humans and animals and are increasingly recognized as significant human pathogens and capable of causing major therapeutic challenges. The aim of this study was to isolate, identify and determine the antimicrobial susceptibility pattern of Enterococcus species in two local cheese sample collected from Akungba and Ikare. The isolation of Enterococcus was carried out using standard culture-based techniques. Antimicrobial susceptibility profile of the Enterococcus species was determined using disk diffusion method. A total number of 93 presumptive Enterococcus species were recovered from forty two different samples over a period of three months. The bacterial count observed on the Bile Aesculin agar ranged from 1.5x104 cfu/ml to 4.6x104 cfu/ml with Akungba sample having the highest bacterial load of 4.6x104 cfu/ml. The Morphology and biochemical characteristics of suspected Enterococcus spp. isolated from the cheese sample revealed Enterococci feacalis as the isolated bacteria. The isolated Enterococcus species were tested against a panel of six antibiotics which include Penicillin G, Vancomycin, Tetracycline, Nitrofurantoin, Ciprofloxacin and Imipenem. It was observed that the isolates were susceptible to tetracycline, imipinem and ciprofloxacin while they are resistant to ciprofloxacin and vancomycin. The prevalence of Enterococci was confirmed with Enterococcus feacium and Enterococcus faecalis as the predominant species isolated in both cheese sample. The ability of Enterococcus species to survive a range of adverse environments allows multiple routes of cross-contamination of Enterococci in causing human disease, including those from food. Overall, greater understanding of the ability of Enterococcus species to survive stresses, of virulence traits and especially of increasing antibiotic resistance, is needed in order to fully appreciate the complexity of Enterococcus species in causing disease.
