Therefore, a change in the mindset as well as the skill set of the leaders has become essential. The lecture was followed bya question and answer session for which many participants actively engaged. The event was organized by SLAAS Section C and Staff Development Committee, Faculty of Engineering, Sri Lanka Institute of Information Technology (SLIIT). A webinar titled “Air-borne transmission of COVID-19 virus on office workspaces: are you prepared for the next wave?” was con- ducted by Prof Mahesh Jayaweera, Environmental Engineer and Professor, Department of Civil Engineering, University of Moratu- wa on 30th July 2020. Prof Jayaweera explained the modes of transmission of COVID-19 virus that are vital in indoor workspac- es, particularly when the ventilation systems are inadequate. The impact of different ventilation systems, namely air-conditioners, ceiling fans and natural ventilation on the transmission of COVID- 19 virus was evaluated. The effectiveness of the use of masks in confined environments was discussed. For different indoor settings, modeling of the infection risk from an asymptomatic pa- tient for other employees of the workspace was performed. The reproduction number for the indoor setting was estimated to pre- dict whether COVID-19 will pass on to the next generations. Final- ly, appropriate engineering interventions for the risk minimization were discussed. The lecture was followed by a discussion session in which a number of participants interacted by asking questions, which displayed their interest in the timely topic. The event was organized by Women Engineers’ Forum (WEF) of the Institution of Engineers, Sri Lanka (IESL) and Section C of SLAAS. A webinar titled “Mobile Edge Computing: Enabling Future Smart Services” was conducted on 4th August 2020 by Dr Uth- pala Premarathne, Senior Lec- turer, Department of Electrical & Computer Engineering, the Open University of Sri Lanka. Dr Premarathne highlighted the increasing market opportunities for computing and IT industries with the current increased de- mand for online services and distance education. The lecture was followed by a question and answer session for which a num- ber of participants actively par- ticipated. The webinar was or- ganized by the General Research Committee and Section C of SLAAS. “Science for Quality Life” 2 A 14 hour online workshop titled “Discovering the world through GIS (with ArcGIS)” was con- ducted on 6th, 8th, 10th, 13th, 15th, 17th and 20th July 2020, which targeted academics, engi- neers, officials and students. The workshop was conducted by Mr Ramesh Ferdinando, Ms Samanmali Matharaachchi and Mr Supun Siri- wardane from GIS Solutions Pvt. Ltd. GIS can be identified as one of the most effective deci- sion support tools which reveals deeper in- sights into data by applying geographic sci- ence with the integration of IT. It helps people to gain actionable intelligence from all types of data. The workshop was or- ganized by SLAAS Section C and Water Forum of the Institution of Engineers Sri Lanka (IESL) and coordinated by Dr Shiromi Karunaratne, President, Section C of SLAAS. The workshop included introduction to GIS and the power of decision supporting, understanding geo- spatial data, data collection methods of GIS, GIS technology, introduction to Web GIS and Web GIS applications. A 15 hour online workshop “ANSYS for Computational Fluid Dynamics (CFD)” was conducted on 8th,9th, 15th and 16th August 2020. The workshop was conducted by OREL Corporation (Pvt.) Ltd., the official ANSYS academic partner in Sri Lanka and the resource persons were Dr Tushar Shar- ma and Eng Lakshitha De Silva. ANSYS sim- ulation software enables predicting how products will operate in the real world. Thousands of universities around the world use ANSYS academic engineering simulation software to help undergraduate students to learn principles of physics and researchers to learn solving complex engi- neering problems. The workshop was or- ganized by SLAAS Section C and Water Fo- rum of the Institution of Engineers Sri Lanka (IESL) and coordinated by Dr Iresha Atthanayake, Secretary, Section C of SLAAS. 3 “Science for Quality Life” Section E1 A webinar on “Energy Harvesting Integrated Circuit Design and Implementation” by Mr Chamith Chandrarathna, Information and Communication System-on-Chip (SoC) Research Center, Kyung Hee University, South Korea was held on 29th July 2020, with the presence of around 50 participants. Dr. Aruna Ranaweera, President/ Section E1, and Senior Lec- turer of the University of Kelaniya, conducted a webinar on “Wireless Power Transfer and its Applications”, jointly orga- nized by the Physic Society of University of Sri Jayewardenepu- ra and SLAAS Section E1. Section E1 and Astronomy Division of the Arthur C Clarke Institute organized a series of webinars on Astronomy targeting the school students on the 24th, 25th, 26th, and 27th August 2020. The expertise of Prof ChandanaJ ayarathne, De- partment of Physics, University of Colombo, Mr Indika Meda- gangoda, Mr Janaka Adassuriya and Mr Mahesh Herath, re- search scientists at Arthur C Clarke Institute participated as resource personnel. The presenters addressed interesting top- ics on Astronomy including History of Astronomy and Path of Sri Lankan Astronomy, Mars Exploration & Solar system, Plan- ets beyond our Solar System and Celestial Sphere. More than 400 school students participated for the entire webinar. www.accimt.ac.lk website provided registra- tion for this webinar. Section E2 Section E2 designed a safety poster to be distributed among the science laboratories in schools. Dr Theshini Perera and Mr Vihanga Ambepitiya (Asst. lecturer, Dept. of Polymer Science and Technol- ogy, SJP) did the preliminary designing in English. The poster was translated to both Sinhala and Tamil languages. Dr L Hasini R Pere- ra translated the content to Sinhala and the content was moderat- ed by Dr Sashipraba M. Vithanarachchi and Prof D P Dissanayake. Dr Jeyasingam Jeyasugiththan (Senior Lecturer, Dept. of Nuclear Science, UOC) and Prof R Senthilnithy( Senior Lecturer, Depart- ment of Chemistry, OUSL) did the Tamil translation together with “Science for Quality Life” 4 Dr Manuja Lamabadusuriya. Developments of the Sinhala and Tamil version posters were coordinated by Dr. Hasini Perera with the help of Mr T N Rangana de Silva (Asst. Lecturer, Department of Chemistry, UOC) and Ms Shalinia Thiruchittampalam (Graduate Student, Department of Chemistry, UOC). A video tutorial on neutralization titration for Advanced level chem- istry students was prepared by Dr L Hasini R Perera, for the SLAAS you tube site. Demonstrations were done by Mr Kamindu Gayashan and Mr Sharada Kothalawala and the videography by Mr Nuwanga Amarasekara, Faculty of Science, University of Colombo. As agreed by Dr C. Dilrukshi Wijayarathna at the meeting held on January 17, 2020 at the Ministry of Environment & Wildlife Re- sources with the GP/SLAAS, the following two (02) research projects are in progress. 1. Evaluation of biodegradability of approved (SLSI) bio-degradable lunch sheets Analysis is carried out with the samples provided by the Central Environment Authority (CEA). Experiments are done by the undergraduate students of University of Colombo under the guidance of Prof R D Wijesekera, Dr S M Vithanarachchi and Dr L H R Perera. Coordinators for the above project are Dr C D Wijayarathna (SLAAS), Dr S M Vithanarachchi, Mr N S Gamage (Director/Investigation, CEA) & Ms Sujeewa Fernando (Ministry of Environment). 2. Development of low cost methodologies for waste treatment for industries Analysis is carried out with the two samples provided by the CEA. Mr Madhawa Botheju (Senior Env. Officer Acting/ Western province, CEA) helped in water sampling. Experiments are done by the undergraduate students of University of Colombo under the guidance of Dr C D Wijayarathna.
