Authors: M S Leelavathi , M P Prasad
Published: February 2021

The Gulf of Mannar is a Marine Biosphere Reserve situated along the east coast of India and Sri Lanka, an area of about 10,500 sq. km which has a luxuriant growth of about 680 species of seaweed belonging to the Rhodophyta, Pheaophyta and Chlorophyta, in both the inter-tidal and deep water regions. Seaweed constitutes a commercially important marine renewable resource. Seaweeds are rich in polysaccharides, minerals, proteins and vitamins. Documented antioxidant activity would elevate their value in the human diet as food and pharmaceutical supplements thus, in the present investigation the sea weed samples were collected in sterile condition and their antioxidant property for methanolic and petroleum ether extract was carried out by reducing power assay. The extraction process was carried out by drying and extracted the fine powder with different solvents. The extracted samples were then dissolved to a stock concentration of 1mg/ml and the reducing power assay was carried out with different concentrations of the sample.The methanolic extract of Cymodoceaeserrulata, Gracillariafolifera and Turbinariaconoides showed higher reducing power when compared to the standard.The petroleum ether extract of Cymodoceaerotundata and Ulvareticulata extracts showed higher activity when compared to the standard whereas Kappaphycussps showed the least activity when checked for its reducing power activity.

Authors: Shivaprakash Y. , Anavekar R.V.
Published: February 2021

Glasses containing Au nanoparticles have been synthesized in the base glass of composition 30Li2O–70B2O3 using gold chloride (HAuCl4.3H2O) as a dopant. The characteristic ruby color has been observed which is attributed due to surface plasmon resonance of the Au nanoparticles. The hue of the color increases with the increase of concentration of the dopant. Presence of the gold nanoparticles has been confirmed by studying the optical absorption spectra in the visible range which show a characteristic absorption peak at ~560nm.  XRD and SEM studies show that the addition of Au increases the kinetics of growth and crystallization. ESR studies indicate that the electronic state of gold is either Au0 or Au+.

Published: February 2021

Fluoride is an acute toxin, with a rating slightly higher than lead and is present in ground water naturally or artificially. Groundwater in India displays the presence of harmful quantities of fluoride. Fluorspar is main constituent of sand. Under the ground in presence of water when this mineral gets appropriate condition for dissolution, it gets dissolve in water and fluoride ion’s get separated from sand. The presence of fluoride causes many health issues to human beings. To reduce these health problems, there is a need to remove fluoride ions from water. This article is brief on different techniques for the removal of fluoride from water.
ACIDOGENIC OFF GAS DIVERSION: A KEY SOLUTION OF TWO STAGE ANAEROBIC DIGESTION PROCESS FOR FOOD WASTE TO BIOENERGY
Authors: Chakraborty Debkumar , Raghu
Published: February 2021

Food waste from households and commercial sources such as canteen, cafeteria and restaurant are usually disposed off in landfills. Limited space and environmental impacts viz generating greenhouse gases and polluting groundwater table are some of the major concerns of food waste disposal in landfill. However, bio processing is a promising alternative for the treatment of food waste due to its high organic content and the potential to recover value added products like biogas and soil conditioner. Two stage anaerobic digestion systems is one of the developed technology in anaerobic digestion system where more energy can be recovered from waste material. But due to its complexity and energy loss researchers need to find probable solution to this and lots of research is going on now a day to improve its energy production rate. Acidogenic off gas diversion is one of the most prominent technology acquire attentions recently. In our discussion we will discuss various prospects of this technology to increase food waste degradation rate.

Published: February 2021

Concrete is frequently utilized infra-structural construction material all over the world. Cement is the main part of the concrete, during its manufacturing emission of gases such as carbon dioxide (CO2) from cement factories create greenhouse effect. In these days various natural pozzolanic materials are used as partial replacement of cement to enhance strength and durability and to reduction in consumption of cement consequently reduction in carbon dioxide (CO2) emission. The aim of this research is to investigate the effect of groundnut shell ash as a cement replacement material on workability and compressive strength of concrete. One mix of ordinary concrete and five mixes of modified concrete were prepared, where cement is replaced by groundnut shell ash from 3% to 15% by weight of cement, with 3% increment with 1:2:4 binding ratio mixed with 0.5 water/cement ratio. The workability and compressive strength of concrete was investigated. The obtained outcomes demonstrated that, groundnut shell ash as a cement replacement material have significant effect on compressive strength of concrete.
CURRENT TRENDS IN THE DEVELOPMENT OF THE WATER MANAGEMENT COMPLEX: UKRAINIAN REALITIES AND INTERNATIONAL EXPERIENCE

Published: February 2021

Aim. The ratification of the Paris Agreement by Ukraine envisages an increase in the ability to adapt to the negative effects of climate change, as well as promoting low carbon development so as not to endanger food production. At the same time, water resources, on the one hand, are one of the most vulnerable to climate change components of the environment from the state of which the food security of the country depends directly, and on the other hand, the activity of the water management complex causes the emergence of both direct and indirect carbon footprint. Therefore, an indispensable prerequisite for sustainable low carbon development is the assessment of the carbon footprint of the main sectors of Ukraine's water management complex and the identification of priority measures for their decarbonisation and adaptation to expected climate change. Methods. The methodological basis for the assessment of the carbon footprint of the main sectors of the water management complex was the life cycle method (LCA), by which, based on the open data of the National Inventory of Anthropogenic Emissions from Sources and Absorption by Greenhouse Gas Absorbers in Ukraine and the statistical analysis of the results of previous studies. By means of systematic analysis of the main factors of greenhouse gas emission in the water management complex of Ukraine, the priority directions of its decarbonisation and adaptation to climate change were determined. Results. The estimated carbon footprint of Ukraine's water complex in 2017 was estimated to be 5.15 million tons of CO2-equiv, which was 1.6% of the total greenhouse gas emissions in Ukraine in 2017, and taking into account the potential carbon footprint enduse processes can be increased by up to 3%. Due to the deterioration of the water supply networks, an average of 35% of the supplied water is lost in Ukraine. Reducing network leakage by at least 10% will reduce carbon footprint by 30,000 tons of CO2-equiv annually. The priority areas for decarbonisation of the water management complex should be modernization of water supply and water treatment infrastructure, improvement of energy efficiency of pumping equipment and introduction of drip irrigation, and its adaptation to climate change – development of the network of green infrastructure. Conclusions. The low-carbon development of the water management system should include the introduction and coordination of such measures, which, on the one hand, minimize the adverse effects of climate change on water resources and contribute to reducing the carbon footprint of water management activities, and on the other hand, guarantee the achievement of sustainable development goals, in particular for ensuring water and society proper sanitary conditions.
FINTECH TOOLS TO REGULATE GRAY EXPORTS OF MILITARY AND DUAL USE GOODS AND TECHNOLOGIES
Authors: Gura Viktoriya , Novytskyi Vitalii , Sizov Alim
Published: February 2021

This article reviews challenges of monitoring and regulation of military and dual use goods and technologies in Ukraine. These challenges are not new; their different aspects have been analyzed previously by many Ukrainian researchers, such as G. Androshchuk, O. Fradynskyi, I. Anokhin, V. Davydovskyy and more, but all earlier analyses, while looking into theoretical and practical aspects of military and dual use goods and technologies export per se, left aside economic and financial aspects of this problem, which are in the focus of our investigation. The object of the study is the export of military and dual use goods and technologies. The subject of the study is the FinTech tools that can be applied to analysis of export of military and dual use goods and technologies. The aim of the research is to analyze the current situation in export of military and dual use goods and technologies and based on results of analysis to outline the FinTech tools that will be useful to evaluate and regulate gray exports of military and dual use goods and technologies. The methodology of research is based on economic analysis in which we have applied an alternative approach to assessing key indicators. Firstly, we determined government budget military expenditure and then compared it with the scope of relevant exports. Further, we analyzed the black market of military and dual use goods and technologies based on the data obtained from the Ministry of Internal Affairs. This analysis demonstrated that official numbers represent only 10% of the total expected amount of military and dual use goods and technologies export; the balance is shared between the domestic black market and gray exports. As result of the research we propose modern FinTech tools, including financial markers and the BlockChain technology, as instruments to detect such gray exports. Financial markers are specific FinTech indicators making banks aware that a transaction involves transfer of military or dual use goods or technologies and therefore requires special attention (to verify whether the company has an appropriate license or whether a license is needed for the transaction etc.) BlockChain is the best solution for tracking the financial marker information since it supports storage of information about the whole transaction chain and analysis of this information on any transaction stage. BlockChain technology can generate information on possible gray exports automatically and chain breaks (where the end user does not typically use or sell military or dual use goods or technologies but is a vendor of conventional goods or technologies).

Published: February 2021

Purpose. The study is aimed at defining the nature of platforms in multi-sided markets in order to find the price optimization model for platform’s goods and services. Methodology. The article used general scientific and special research methods. The generalization of the main methodological approaches to the study of the essence of multi-sided markets, the identification of factors affecting the platform’s pricing strategy were based on the methods of dialectics, scientific abstraction, and systemic analysis. The basis of the study of the essence of “platforms” was laid on the use of the following methods: analysis and synthesis, induction and deduction, generalization. Economic and mathematical modeling, scientific abstraction, systemic structural analysis contributed to the development of our own model of the optimal strategy for choosing the price of goods and services by platforms. Findings. The article defines factors that affect the pricing of platform’s goods and services. An economic and mathematical model has also been developed to determine an optimal strategy for choosing the price in terms of Nash equilibrium. There have been identified three main factors, which produce the most significant impact on the price of goods and services of platforms: marginal costs; rate of return of another product is being implemented by the platform; elasticity of demand and price. Practical implications. In the conclusions, not only the advantages but also the limitations of the proposed economic and mathematical model have been pointed out, which can be addressed in further studies and implemented into specific living model of economic decisions while price optimization model for platform’s goods and services in multi-sided markets. Originality/value. The article is generalizing the previous experience within the niche of price optimization model. Also authors have developed their own economic and mathematical model of the optimal strategy for choosing the price for the platform’s products or services, which enabled us to identify its dependence on 3 main factors: marginal costs, rates of profitability of other products sold by the platform, elasticity of demand and price. These results can be overcome in future studies. The results and conclusions have been done by the authors and are totally original.

The Impact of Service Employees and Servicescape on Customers’ Perception of Quality Improvement Efforts
Authors: Nguyen Nha , LeBlanc Gaston
Published: February 2021

The present study contributes to the understanding of the influence of service employees and the tangible components of the service production and delivery system on perceptions of quality improvement efforts in a service organization. A hierarchical multiple regression with interaction analysis was performed on data collected from a convenience sample of 435 respondents in a higher education institution to assess the main effect of service employees and servicescape, as well as their interactive effect, on customers’ perception of the institution’s quality improvement efforts. The results show a significant effect of service employees, servicescape as well as the interaction between service employees and servicescape in their influence on customers’ perception of quality improvement efforts. The results also reveal that the servicescape intervenes as a moderator variable in the relationship between service employees and quality improvement efforts. Service organizations should therefore focus on the crucial role of service employees during the service encounter and recognize the importance of the servicescape, in view of increasing customers’ favourable perceptions towards the service organisation’s capability to provide better quality in order to satisfy their needs. The study has limited generalization given the convenience sample and the great variety of service industries. It would be helpful to realize similar studies in other service settings and to explore the exact nature of the interaction between service employees and servicescape. Keywords: Service employees, servicescape, quality improvement efforts
An Explanation of a Gender Earnings Gap in the Veterinary Profession
Authors: Smith David , Vardiabasis Demos , Seaman Samuel , Adamo Yury
Published: February 2021

Analysis of a unique data set of U.S. veterinary firms and veterinarians provides evidence of significant differences in earnings between self-employed males and females. After controlling for important concomitant variables, including training and experience, self-employed female veterinarians generally own smaller clinics and have lower earnings than their male counterparts. This study considers which demographic/economic factors may be associated with observed gender differences in earnings. The gender gap for average earnings is about 44 percent; however, when controlling for certain characteristics, the gap narrows to as little as 23 percent, depending on the model specification. Firm size was found to be the strongest contributing factor in explaining the gender gap in earnings, and so, possible explanations for differences in firm size have also been discussed. Whilst the analysis is not conclusive, there is evidence that self-employed females may face customer discrimination, which may constrain the growth and size of female-owned firms.

Going local – Providing a highly detailed Green Infrastructure geodata set for assessing connectivity and functionality
Authors: Danzinger Florian , Fuchs Stefan , Wrbka Thomas
Published: February 2021

Green Infrastructure (GI) defined as a strategically planned network of natural and semi-natural areas is a key strategy in the European biodiversity strategy and the landscape connectivity agenda. To implement this approach in Central Europe’s (CE) landscape planning policies the Interreg project MaGICLandscapes (ML) tried to operationalise the GI concept in CE as well as in nine case studies, to provide land-managers, policy makers and communities with tools and knowledge, at different spatial levels.

Based on the example of the Austrian case study area, the aim of this paper is to present an easy to use approach, as implemented in ML, for producing a highly-detailed regional GI database to overcome the difficulty of realising comprehensive biotope mapping surveys as well as the rather coarse resolution of CORINE Land Cover (CLC). By compiling regional cadastral and agricultural information, highly detailed data on the water network as well as Pan-European High Resolution Layers (HRL), this detailed representation of the regional GI network allows to enhance the regional applicability and acceptance of GI initiatives and provides a crucial foundation for assessing GI connectivity and functionality to develop evidence-based strategies and action plans through stakeholder involvement to direct future actions and investment in GI.

Climate Variability of the Northern Argentinean Shelf Circulation: Impact on Engraulis Anchoita
Authors: Auad Guillermo , Martos Patricia
Published: February 2021

A high-resolution ocean model and hydrographic observations are used to characterize the shelf circulation of the northern Argentinean shelf during the study period (1993–2008) and ultimately to explore possible linkages among atmospheric, oceanic, and biological climatic variability. Abundance of larvae and eggs of the local anchovy species, Engraulis anchoita, exhibit a spatial and temporal variability similar to those stocks found in other parts of the world and that we interpret in the context of the particularities of the local circulation and hydrography. Two (statistically) coupled modes of wind stress-surface velocity are described and interpreted in terms of historical and new information. A complex picture emerges in which the intensity of both a thermal shelf front, the alongshore flow, and larvae abundance would be connected and forced by local wind stresses. For all areas examined on the shelf, the larvae/egg abundance would not be very sensitive to short-lived climatic fluctuations (e.g., year-to-year) but they would be indeed to regime shifts. The shallow shelf area bounded by the 39°S and 41°S parallels would expose a clearer linkage between physical and biological variables than that north of 39°S. We attribute this fact to the particular physical conditions found in the southernmost area, which would favor an increased habitat quality for Engraulis anchoita.
More Matter Than Antimatter, All Falling Down
Authors: Maes Stephane
Published: February 2021

In a multi-fold universe, gravity emerges from Entanglement through the multi-fold mechanisms. As a result, gravity-like effects appear in between entangled particles that they be real or virtual. Long range, massless gravity results from entanglement of massless virtual particles. Entanglement of massive virtual particles leads to massive gravity contributions at very smalls scales. Multi-folds mechanisms also result into a spacetime that is discrete, with a random walk fractal structure and non-commutative geometry that is Lorentz invariant and where spacetime nodes and particles can be modeled with microscopic black holes. All these recover General relativity at large scales and semi-classical model remain valid till smaller scale than usually expected. Gravity can therefore be added to the Standard Model. This can contribute to resolving several open issues with the Standard Model. In particular with chirality flips of fermions induced by gravity, right-handed neutrinos (and left-handed anti-neutrinos) can appear in flight and now acquire mass when encountering Higgs bosons. Because perturbatively self-gravity effects may be stronger for anti-neutrinos, the chirality flips in flight will trap longer in flight right-handed anti neutrinos than left-handed neutrinos; creating a matter antimatter asymmetry. While very small this can explain the dominance of matter of antimatter, hence why we exist. As we visit the properties of antimatter, we also predict that, in a multi-fold universe, anti-matter is attracted by gravity, not repelled; something that is still an open issue today in Physics.

Published: February 2021

Despite the increase in digital media adoption among youth growing up in low and middle income countries, there is an insufficient understanding of adaptive and risky online practices within these settings. There is also a dearth of programs adapted to youth’s contextualized needs that can promote adaptive use of technologies in these settings. The Transitions project aims to (1) understand how children and adolescents access, use and appropriate digital media in Perú, and (2) use this information to adapt a culturally and developmentally appropriate digital citizenship program. The Transitions project is a researcher-practitioner collaboration between the Adolescent Research Collaborative (ARC) at UC Berkeley, Innova Schools in Latin America, and U.S.-based Common Sense Education. In this multiple wave project, we will work with up to 24, 500 children and adolescents aged 9 to 17 years, and 1,021 tutors within a large, low-cost school network that serves low to middle income urban families across Perú. To date, there are 4 waves of this project (the fifth wave is currently underway). Each wave includes surveys on digital media use, well-being and mental health. In each wave, participants also complete a short course on digital citizenship as part of the school advisory or homeroom period. Some waves have included qualitative data collection, gathered from focus groups and workshops. This study will shed light on how youth in Perú access, use and appropriate digital media. This knowledge will enhance our global conceptualization of the relationship between digital media and youth well-being by providing cultural specificity to our general understanding of the developmental science principles at play. In addition, this project will inform the ongoing development of evidence-based programs that can empower youth online.
COVID-19 critical patients: poor tolerance to hypoxia, insufficient red blood cells, and hypercapnia leading to ventilator ineffectiveness?
Authors: Zubieta-Calleja Gustavo , Zubieta-DeUrioste Natalia

Sustained hypoxia normally induces a carotid body upregulation of AT1 receptor expression, increasing response to Angiotensin-II(3). However, ACE2 receptors blocked by CoV-2 as their entry port could decrease Angiotensin-II production. Thereby, carotid body hypoxia sensing could be impaired. This “numbness” interferes with normal pulmonary-cardiovascular compensatory response. Rapid progression to extreme hypoxia in COVID-19 without initial shortness of breath and sudden death could ensue. Following this hypothesis, incipient asymptomatic COVID-19 patients with low pulse oximetry (<90% at sea level and <80% in La Paz at 3,600m) can be diagnosed before temperature rise. Early treatment could avoid progression. Pulse oximetry in public places is recommended.

COVID-19 lockdowns around the world have markedly disrupted adolescents' in-person social networks, putting them at risk for social isolation, loneliness and their detrimental consequences. During lockdown, social media can help adolescents to maintain and develop relationships across distance, particularly with peers. In this longitudinal, observational study following 735 Peruvian adolescents (11-17 years old) from low-to-middle income urban settings, we investigated whether online experiences relate to loneliness during initial stages of lockdown in Perú. We found that loneliness generally did not change between week six and week eleven of lockdown, was higher for females and similar for all grades. Both positive and negative online experiences were more frequent for older students, and females experienced more negative online experiences than males. Loneliness was negatively associated with positive online experiences, with the reverse pattern for negative online experiences, when controlling for family social support and screen time. Our results highlight the association between online experiences and well-being, suggesting that positive online experiences can be an important vehicle for peer relationships in the face of lockdown.

SARS-CoV-2 resulting in COVID-19 can affect the brain and cause neuropsychological disorders (e.g., executive dysfunction and memory difficulties). Recently the presence of more focal and isolated neuropsychological signs has been also reported, in the domain of language disorders (e.g., alexia without agraphia, conduction aphasia). We reported on patient LM affected by a left occipito-temporal ischemic stroke after SARS-CoV-2. LM had a largely preserved overall cognitive profile, but he presented with severe alexia without agraphia. We suggest that focal and isolated neuropsychological dysfunction can be observed in patients with stroke after SARS-CoV-2. Neuropsychological assessment and rehabilitation should be promptly provided to these patients.

Coming Together But Staying Apart: Continuity and Change In The Austrian And Swiss Varieties of Capitalism
Authors: Afonso Alexandre , Mach André
Published: February 2021

This chapter assesses institutional continuity and change in the varieties of capitalism in Austria and Switzerland. In the face of growing internationalisation, budgetary constraints and European integration, continuity and change have been determined by prevailing interest configurations and institutional limits in terms of public intervention and private governance. Hence, private employer dominance in Switzerland has fostered ra- pid change in areas where private regulation prevailed, such as corporate gover- nance, whereas institutional veto points have strongly limited change in areas where public intervention was necessary. By contrast, the larger scope of public intervention in Austria and its more majoritarian features have allowed more space for change in welfare reforms while the strong institutionalisation of corporatist institutions in labour market governance, for instance, has made it more resilient to change than Switzerland. In this respect, Austria and Switzerland provide good examples of how institutional change is dependent on the respective share of public regulation and private governance.

SARS-CoV-2 is notable both for its rapid spread, and for the heterogeneity of its patterns of transmission, with multiple published incidences of superspreading behaviour. Here, we applied a novel network reconstruction algorithm to infer patterns of viral transmission occurring between patients and health care workers (HCWs) in the largest clusters of COVID-19 infection identified during the first wave of the epidemic at Cambridge University Hospitals NHS Foundation Trust, UK. Based upon dates of individuals reporting symptoms, recorded individual locations, and viral genome sequence data, we show an uneven pattern of transmission between individuals, with patients being much more likely to be infected by other patients than by HCWs. Further, the data were consistent with a pattern of superspreading, whereby 21% of individuals caused 80% of transmission events. Our study provides a detailed retrospective analysis of nosocomial SARS-CoV-2 transmission, and sheds light on the need for intensive and pervasive infection control procedures.

A Steady State Semi-analytical Approximation of Melt Pool Evolution in Pulsed Laser Surface Melting
Authors: Mistry Utsavkumar , Vadali Madhu
Published: February 2021

Pulsed laser surface melting (pLSM) is a technique that offers an efficient and effective way to modify the geometry surfaces without any addition or removal of material. The resultant surface geometry plays a critical role in several applications. This paper presents a steady-state thin-film approximation of the melt pool created by pLSM and the resulting semi-analytical solution for the evolved surface geometry. These predictions of the semi-analytical solution are then compared with a validated numerical solution. The comparison demonstrates a good match with errors ranging from ~4% to ~25% across several pulse duration. Larger errors are observed at comparatively lower and higher pulse duration, and smaller errors are observed for intermediate pulse duration values. Overall, the thin film solution is a reasonable and useful approximation of the evolved surface geometry through the pLSM process, thus saving significant computational costs.
