Title: Marine macroalgae - applications in the industrial sector and therapeutic potential

Biography:

Ana Marta Goncalves has her expertise in the evaluation of biochemical pathways and the impacts of stressors in aquatic species to assess and improve the health status of the ecosystems and wellbeing. Her interests are also focused at the valorization of marine resources and their applications to food industry. Sustainable and healthy food products from marine resources (seaweed) are developed for a premium diet with appropriate nutritional balance and potential functional benefits based on a circular economy production. Based on the response of aquatic species to stressors and on the mode of action, her studies also highlight the best biomarker to function as early warning indicators. These tools can be used to monitor water changes and provide a broad measure of the impacts, with particular interest to the management of aquatic systems. This approach allows to assess the body condition of the individuals and to characterize the diet food source.

Abstract:

At the last decade increased the interest and search for new natural compounds from marine biodiversity to discover novel bioactive substances. It is expected that many naturally bioactive marine compounds with novel structures and bioactivities may be found among marine metabolites. Moreover, there is also an urgent need for bioactive compounds environmentally friendly or with “green” chemical properties. Still, there is a long way from discover to the applications of this new natural compounds, because they need to be cost efficient and be economically viable from an ecological point of view. Marine macroalgae produce significant amounts of primary and secondary metabolites that present a wide variety of bioactive properties, including antioxidant, antiviral, antimicrobial, antitumoral, anti-inflammatory, anti-aging or immunomodulatory potential, with also antibiotic properties. These molecules are promising candidates for many possible applications such as in pharmaceutical, nutraceutical, cosmetic and medicine areas but also in agriculture or feeding. These applications may promote several benefits to humans’ daily life, and so to a better quality of life. Still, some substances may be poisonous to humans and to other organisms, or become toxic upper to a certain quantity. In this topic will be focused the marine macroalgae benefits, applications in industrial sector and therapeutic potential.

Abstract:

Many ‘Viral Epidemics Human Challenges’ has been faced from past two decades like the ‘Midst of 5th Pandemic COVID-19, coming from animals’, effects on environmental science, more than 88 million infections and more than 1.8 million death of human lives, humancivilization, agriculture, global socio-economy, health-travel-education, and clinical-research, professional and social life, and increases long term neurological-effects causing the risk of cognitive decline and dementia later in life also in the world. The low-income-households, senior-citizens, and street-children are not able to manage. So the scientists and engineers all over the world collectively have been tried to speedily develop proper cost-effective allergic-free vaccines against novel coronavirus for total global recovery by initiative policy, and the Government of India has necessitated to the formulation of a new outlook and strategy for Science, Technology, Innovation and Policy (STIP) by the way of its decentralized, bottom-up and inclusive design process aims to strategize priorities, sectorial focus and methods of research and technology development for larger socio-economic welfare, based on the theme “Vision 2040” that would help policymakers, and the global public and private partnerships may allow more entities ‘Common Goals’ for the effective advancement of science and technology- ‘Innovative Partnership’ and fulfill the objectives and resources that would retain the human civilization's in the ‘Old or New Normal Forms’.

Title: How El-Nino/La-Nina & India Ocean Dipole (IDO) Influence on Myanmar Rainfall Distribution

Biography:

Abstract:

Every agriculture countries essential need to examine the rainfall pattern or it influences. This study examined the relative impacts of Niño and Indian Ocean Dipole (IOD) anomalies events on Myanmar summer monsoon precipitation (June to September) on a sub-regional scale. This study used the Niño3-4 and IOD index data sets for 1990-2019 from UCAR and NOAA. As well as ERA5- Reanalysis Data precipitation data, summer monsoon precipitation data across Myanmar for homogeneous and sub-regional precipitation data sets. The spatial distribution of partial correlations between IOD and summer monsoon rainfall over Myanmar indicates a significant influence on rainfall along the monsoon trough regions, parts of the southwestern coastal regions of Myanmar, and over some parts of Thailand. For the region of rainfall, we take average area (90E-105E and 10N-28N) as Myanmar, and about the time scale, selected summer monsoon season (JJAS) data for every dataset are used. Niño and IOD indexes data are already defined regions but time is collected. For Niño anomaly (El Niño or La Niña) events, selected data are defined as +/- 4 of monthly SST average of Niño3-4 region. The positive and negative phase of IOD is defined as the above paragraph and selected data are defined as +/-4 of monthly two SST anomalies difference. We analyze all dataset the whole statistics analysis base on the following formula from Guidelines on the Calculation of Climate by World Meteorology Organization especially anomalies and correlation analysis. Study the relative influences of the IOD and the Niño anomalies on the summer rainfall of these regions by grid data analysis with Open-Grads climate data display to understand the impacts of the IOD/Niño anomalies on Myanmar monsoon rainfall at a regional scale. If IOD and Niño anomalies are the same values positive or negative, rainfall distribution was randomized distribution. If IOD negative anomaly or negative phase can impact monsoon rainfall over Myanmar. Found Niño can impact positively correlation over Myanmar monsoon rainfall distribution during IOD normal situations with weak correlation. And during IOD normal year rainfall distribution are not enough strong correction with Niño directly and not a correlation with for IOD anomaly year rainfall. We can also found a strong negative correlation (-0.3 to -0.4) with strong regression values (- 0.3 to -0.6) between SST and Myanmar monsoon rainfall distribution. As the results of the 3 variables correlation, IOD and rainfall distribution had a negative correlation and IOD and Niño had a positive correlation. Their turning point is around values of +/- 0.3 and its values indicate a weak positive (negative) linear relationship via a shaky linear rule. The influence of the IOD negative phase on monsoon rainfall over Myanmar is more than that of positive IOD during Niño normal situation.

Abstract:

COVID-19 is a contagious illness that is caused by a newly recognized coronavirus. It has become the largest pandemic that has issued emergency all across the world. The objective of this research is to show how environment has been positively affected by it particularly in India. Our research shows that although human living and health are our major and immediate issues to concern, water and environmental systems from rural to urban scales have seen noticeable productive impacts due to the depletion of pollutants loading from industries, vehicle emission, and other sources. Seeing the past plots, the research also indicates that the pace and range of improvement seen would have been impossible without supreme actions that have been imposed on the society due to the epidemic, at the cost of several millions of dollars across the nation. Therefore, the research furtherfocuses on how India’s environmental problems can be tackled systematically so that country can aim green future even after exemption from the rules of home quarantine that has been imposed due to the ongoing pandemic.

Title: Circular economy for textiles as engrained in the traditional Indian life

Biography:

Anupriya Aggarwal is working at Indian Institute of Technology, India.

Abstract:

When compared to the per capita textile waste in other countries, the waste generated by the Indian population is significantly low (0.79kg per capita). There are variousfactors which lead to low textile waste such as the traditional practices of reuse, the design of clothing, lower disposable income and so on. However, the largest eliminators of the textile waste are principles of reuse engrained in the traditional Indian practices and lifestyle like the reuse of the garment by multiple members of the family enabled by (usually a) patrilineal cohabitation known as the Joint family system; and the basic tenets of circularity imbibed in the practice of wearing rectangular pieces of unstitched fabrics like sarees, lungis, veshtis. In this paper we will do a detailed study of how these two traditions encourage a circular economy for textiles.
