The University in Africa and Democratic Citizenship
Authors: Luescher-Mamashela Thierry M. 
Published: March 2021

Whether and how higher education in Africa contributes to democratisation beyond producing the professionals that are necessary for developing and sustaining a modern political system, remains an unresolved question. This report, then, represents an attempt to address the question of whether there are university specific mechanisms or pathways by which higher education contributes to the development of democratic attitudes and behaviours among students, and how these mechanisms operate and relate to politics both on and off campus.
The research contained in this report shows that the potential of a university to act as training ground for democratic citizenship is best realised by supporting students' exercise of democratic leadership on campus. This, in turn, develops and fosters democratic leadership in civil society. Thus, the university's response to student political activity, student representation in university governance and other aspects of extra-curricular student life needs to be examined for ways in which African universities can instil and support democratic values and practices. Encouraging and facilitating student leadership in various forms of on-campus political activity and in a range of student organisations emerges as one of the most promising ways in which African universities can act as training grounds for democratic citizenship.
The project on which this report is based forms part of a larger study on Higher Education and Democracy in Africa, undertaken by the Higher Education Research and Advocacy Network in Africa (HERANA). HERANA is coordinated by the Centre for Higher Education Transformation in South Africa.
Driving Change
Authors: Gibbon Trish 
Published: March 2021

Driving Changetells a story that exemplifies a basic law of physics, known to all the application of a relatively small lever can shift weight, create movement and initiate change far in excess of its own size.
It tells a story about a particular instance of development co-operation, relatively modest in scope and aim that has nonetheless achieved remarkable things and has been held up as an exemplar of its kind.
It does not tell a story of flawless execution and perfectly achieved outcomes: it is instead a narrative that gives some insight into the structural and organisational arrangements, the institutional and individual commitments, and above all, the work, intelligence and passion of its participants, which made the South Africa Norway Tertiary Education Development (SANTED) Programme a noteworthy success.
Las playlists como espacios de mediación y su concentración en Argentina
Authors: Olguin Nahuel Marcelo 
Published: March 2021

Con la consolidación de internet y la exponencial multiplicidad de la oferta musical, las listas de reproducción representaron una herramienta útil para que los usuarios tuvieran una mejor y más personalizada experiencia dentro de las plataformas de streaming de música. Sin embargo, las playlists también se consagraron como nuevos espacios de mediación en donde los diferentes actores de la industria fonográfica intentan intervenir con el fin de obtener el mayor beneficio. Lo cual adquiere una trascendencia aún superior si se tiene en cuenta que el sector de la música grabada está excesivamente concentrado.
Este marco obliga a pensar cómo se conforman las listas de reproducción, hasta dónde llega su importancia en la industria fonográfica, quiénes son sus principales propietarios y qué implicancias puede generar un alto grado de concentración.

Recovery and Screening of α-Galacotosidase Producing Lactic Acid Bacteria from Fermented Dairy Products
Authors: Prasad Bhairav , Narang Alisha , Mishra Mohit 
Published: March 2021

Lactic acid bacteria (LAB) present in fermented foods has long been consumed by humans without any obvious adverse effects. Therefore, they are potent candidates as vehicles for the delivery of digestive enzymes. Stachyose, a tetrasaccharide, is believed to contribute to flatulent properties of soyabeans that limit their use for human consumption. LAB including some Lactobacillus plantarum, L.fermentum,L. buchneri and reuteri hydrolyze α- galactosides or non-digestible carbohydrates into digestible carbohydrates during fermentation. These bacteria are therefore a source of α -galactosidase. If soy milk could be fermented with these microorganisms that utilize stachyose either to produce acid or to hydrolyze it to mono and disaccharides, the product thus prepared ought to be less flatulent and therefore, more acceptable. In present study, total 27 lactic acid bacteria were recovered selectively on MRS agar from the various milk and milk products. All the 27 isolates were characterized morphologically and the colonies were white to cream and gram positive. Out of 27 LAB only 5 isolates were found to be positive for α- galactosidase enzyme. α-galactosidase activities were determined by using p-NPG. All 5 α- galactosidase producer were further subjected for various biochemical characterization for partial identification and were catalase negative, and casein hydrolysis, sugar fermentation, nitrate reduction positive. Reduction of α- galactosides by the 5 selected isolates were evaluated. The isolate, RLAB α-4, CLAB α-14, CLAB, CLAB α-20 α-18 and WLAB α-25 degraded 67.56 %, 45.94%, 54.05%, 70.27%, and 64.86% α- galactosides respectively. CLAB α-20 degraded maximum concentration of α- galactosides and RLAB α-14 degraded least concentration of α- galactosides.

Published: March 2021

Coronaviruses are large group of enveloped viruses with unsegmented, single-stranded, positive-sense RNA as genetic material. These are collection related RNA viruses that cause diseases of economically important vertebrate viz. mammals and birds. In humans, these viruses cause respiratory tract infections that can range from asymptomatic to life threatening. The asymptomatic disease include very similar to some cases of the common cold, while other deadly varieties can cause SARS, MERS, and COVID-19. The SARS-CoV (severe acute respiratory syndrome coronavirus) and MERS-CoV (Middle East respiratory syndrome coronavirus) are zoonotic origin and extremely pathogenic coronaviruses that can cause localized and worldwide outbreak. The novel Coronaviruses, COVID-19 posses a unique morphology. The outer surface of the virus bearing surface spike and reveled like crown hence being named corona virus. The mode of replication of the virus is very unique as it replicate through the generation of nested set of viral mRNA. The HCoV (Human coronavirus) cause respiratory complication with asymptomatic to life threatening outcomes. From the past 15 years we have witnessed appearance of two zoonotic, extremely pathogenic human corona viruses the: SARS-CoV and MERS-CoV.

Abstract. In March 2020, non-pharmaceutical intervention measures in the form of lockdowns were applied across Europe to urgently reduce the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus which causes the COVID-19 disease. The aggressive curtailing of the European economy had widespread impacts on the atmospheric composition, particularly for nitrogen dioxide (NO2) and ozone (O3). To investigate these changes, we analyse data from 246 ambient air pollution monitoring sites in 102 urban areas and 34 countries in Europe between February and July 2020. Counterfactual, business-as-usual air quality time series are created using machine-learning models to account for natural weather variability. Across Europe, we estimate that NO2 concentrations were 34 % and 32 % lower than expected for respective traffic and urban background locations, whereas O3 was 30 % and 21 % higher (in the same respective environments) at the point of maximum restriction on mobility. To put the 2020 changes into context, average NO2 trends since 2010 were calculated, and the changes experienced across European urban areas in 2020 was equivalent to 7.6 years of average NO2 reduction (or concentrations which might be anticipated in 2028). Despite NO2 concentrations decreasing by approximately a third, total oxidant (Ox) changed little, suggesting that the reductions in NO2 were substituted by increases in O3. The lockdown period demonstrated that the expected future reductions in NO2 in European urban areas are likely to lead to widespread increases in urban O3 pollution unless additional mitigation measures are introduced.
A 2-decade (1988–2009) record of diatom fluxes in the Mauritanian coastal upwelling: impact of low-frequency forcing and a two-step shift in the species composition
Authors: Romero Oscar E. , Ramondenc Simon , Fischer Gerhard 
Published: March 2021

Abstract. Eastern boundary upwelling ecosystems (EBUEs) are among the most productive marine regions in the world's oceans. Understanding the degree of interannual to decadal variability in the Mauritania upwelling system is crucial for the prediction of future changes of primary productivity and carbon sequestration in the Canary Current EBUE as well as in similar environments. A multiyear sediment trap experiment was conducted at the mooring site CBmeso (“Cape Blanc mesotrophic”, ca. 20∘ N, ca. 20∘40′ W) in the highly productive coastal waters off Mauritania. Here, we present results on fluxes of diatoms and the species-specific composition of the assemblage for the time interval between March 1988 and June 2009. The temporal dynamics of diatom populations allows the proposal of three main intervals: (i) early 1988–late 1996, (ii) 1997–1999, and (iii) early 2002–mid 2009. The Atlantic Multidecadal Oscillation (AMO) appears to be an important driver of the long-term dynamics of diatom population. The long-term AMO-driven trend is interrupted by the occurrence of the strong 1997 El Niño–Southern Oscillation (ENSO). The extraordinary shift in the relative abundance of benthic diatoms in May 2002 suggests the strengthening of offshore advective transport within the uppermost layer of filament waters and in the subsurface and in deeper and bottom-near layers. It is hypothesized that the dominance of benthic diatoms was the response of the diatom community to the intensification of the slope and shelf poleward undercurrents. This dominance followed the intensification of the warm phase of AMO and the associated changes of the Atlantic Meridional Overturning Circulation. Transported valves (siliceous remains) from shallow Mauritanian coastal waters into the bathypelagic should be considered for the calculation and model experiments of bathy- and pelagic nutrients budgets (especially Si), the burial of diatoms, and the paleoenvironmental signal preserved in downcore sediments. Additionally, our 1988–2009 data set contributes to the characterization of the impact of low-frequency climate forcings in the northeastern Atlantic and will be especially helpful for establishing the scientific basis for forecasting and modeling future states of the Canary Current EBUE and its decadal changes.

BOUNDARY LAYER CONTROL OF A RADIATIVE CASSON FLUID FLOW PAST A PERMEABLE RIGA-PLATE WITH UNIMOLECULAR CHEMICAL REACTION
Authors: Loganathan Parasuraman , Deepa Krishnamurthy 
Published: March 2021

The buoyancy driven, chemically reacting and radiative Casson fluid flow past an impulsively started permeable Riga-plate is investigated through the numerical solution obtained by Crank-Nicholson implicit scheme of finite difference method. The main aim of this study is to control the boundary layer separation. Escalating modified Hartmann number and the distance from leading edge of the plate reduces the viscous drag so that the separation can be controlled. Effects of permeability on the flow configuration are also elucidated. The results are validated by comparing the solutions of the literature which already exists.

Published: March 2021

In last years, sorption-enhanced steam reforming of ethanol (SESRE) has become an interesting alternative for the industry, since it offers high H2 purity with a simpler and smaller system. In this study CaO derived materials were synthesized to improve multicyclic CO2 sorption-desorption stability. A dispersant and inert phase (Ca12All4O33) was incorporated into CaO structure. The effects of CaO:Ca12Al14O33 ratio on the characteristics of the new absorbents and on their performance in sorption-enhanced steam reforming of ethanol were analyzed. The results obtained indicate that the absorbent 85% CaO – 15% Ca12Al14O33 had significantly improved cyclic reaction stability. Additionally, it was proved that with this adsorbent CO purity on wet basis was lower than 2 %, making it possible to attain in only one reaction stage the CO purity obtained after de WGS reactor.

Authors: Virgilio Emanuel Martín , Padró Cristina Liliana , Sad Maria Eugenia 
Published: March 2021

The C-O hydrogenolysis of Erythritol to Butanodiols was studied in aqueous solution at 473 K and 25 bar of H2 using Rh/ReOx/TiO2 and the monometallic Rh/TiO2 and ReOx/TiO2 catalysts. The solids were characterized by temperature programmed reduction (TPR), TEM and XPS. TPR and XPS showed that ReOx species are close to Rh particles leading to reduction at lower temperature than Re on monometallic catalyst. However, some segregated Rhenium species were suspected by TPR profile for the bimetallic catalyst and detected by TEM. Re/TiO2 exhibited low activity forming only products from dehydration and epimerization. Although Rh/TiO2 showed high activity (total conversion at 14 h), was more selective to C-C cleavage leading to lower carbon products. Rh/ReOx/TiO2, showed instead, a good activity and selectivity towards C-O hydrogenolysis route yielding 37.5% of Butanodiols. Activation energy and reaction orders on ERY (0.58) and H2 (0.53) were estimated from experiences made at different reaction conditions
QUALITY PARAMETERS AND DRYING KINETICS OF ULTRASOUND PRETREATED FERMENTED BLACK TABLE OLIVES
Authors: Aydar Alev Yüksel 
Published: March 2021

The effect of ultrasound (US) pretreatment on microwave drying parameters including drying rate, moisture ratio and effective diffusivity and quality properties such as total phenolic and color parameters (L*, a*, b*, C, ΔE and H°) of black table olive slices were determinated. 10 minutes ultrasound pretreatment decreased drying time of black table olive slices by 31.81%, 41.37% and 42.85% compared to control samples dryed at 180, 450 and 800 W, respectively. Weibull and Diffusion models could precisely fit the drying behavior of black table olive slices (R2 > 0.9950). Microwave drying had a negative effect on phenolic contents of olives, whereas US pretreatment preserved phenolic compounds and enhanced the color parameters of samples. Higher effective diffusivity (Deff) values were obtained when the drying was combined with US pretreatment. Microwave drying with ultrasound pretreatment could improve drying process, since it accelarated drying rate and preserved the phenolic content and color parameters.

Authors: Fang Yingwu 
Published: March 2021

The aim of this article was to address the de-orbit behaviors of space-based laser driving small scale space debris in low earth orbit (LEO) based on different orbit and laser parameters in coplanar/non-coplanar conditions. The de-orbit model of space-based laser irradiating small scale space debris was established, the de-orbit rules of irradiation angle and irradiation distance with action time in different orbital inclination and right ascension of the ascending node (RAAN) were investigated by numerical simulations, and the change rules of the perigee altitude with the number of laser pulses were discussed in different orbital inclination and RAAN. As a result, the clearance window of removing small scale space debris was described in detail. These results of numerical simulations will provide theoretical guide for designing clear schemes and selecting efficient parameters.
