South Eastern University of Sri Lanka
Ampara, Sri Lanka

The South Eastern University of Sri Lanka is a public university in Oluvil in Sri Lanka. Established in 1995 as a university college, it became a full fledged university in 1996. Like all public universities in Sri Lanka, SEUSL receives the bulk of its funding from the University Grants Commission , part of the Ministry of Higher Education in Colombo. The UGC and the central government therefore exert a great deal of control over SEUSL.The campus is in Oluvil near Akkaraipattu. It also has faculty in Sammanthurai. The university currently has four faculties . SEUSL offers undergraduate and postgraduate courses that award degrees such as BA, BBA, BCom, BSc and MBA.The university had 2,237 students and 338 employees in 2010. It is the thirteenth largest university in Sri Lanka in student numbers. In 2009/10 the university admitted 836 undergraduates. SEUSL had a recurrent budget of Rs. 277 million and a capital budget of Rs. 121 million in 2010.

This paper gives an overview of the adoption and implementation of Eurocodes in Sri Lanka, especially Eurocode 6 for design of masonry structures. Sri Lanka is a small developing country and to date structural engineers have been using British Standards as guidelines for design of masonry structures. However the withdrawal of British Standards in 2010 and the decision to make no further updates to those standards have made countries like Sri Lanka to adopt the Eurocodes. The Eurocodes permit flexibility for their adoption to country specific needs. The factual challenges of using Eurocode 6 in the structural design industry in Sri Lanka and development of the Sri Lanka National annex for Eurocode 6 are highlighted. Additionally, in order to highlight the main differences, comparisons are madebetween the design approaches recommended by Eurocode 6 and those in the previous BS 5628. © 2016 Taylor & Francis Group, London.

The behaviour of masonry under axial compression is influenced by the relative stiffness of masonry units and mortar, the thickness of mortar joints and the shape of the units. Therefore it is believed that by reducing the thickness of mortar joints relative to the unit height and increasing the mortar strength to the unit strength ratio, the compressive strength of masonry could be increased. The thin layered masonry construction holds the above mentioned characteristics as a masonry system. This paper presents an experimental study carried out to examine the compressive strength characteristics of thin layered mortared concrete masonry. Masonry prisms and wallettes with different concrete blocks and thin layer mortar were constructed and tested under uniaxial compression. The results of the experimental program were compared with a database of experimental datasets extracted from the past research papers published in journals and conference proceedings. It is found that, on average, the compressive strength of thin layer mortared concrete masonry considered in this research is marginally (13%) higher than that of the conventional masonry and mainly depends on the unit to mortar height ratio. Also the thin layered mortared masonry exhibit lower deformation characteristics than the conventional masonry. © 2016 Taylor & Francis Group, London.

Polypyrrole polymer films doped with the large, immobile dodecylbenzene sulfonate anions operating in alkali halide aqueous electrolytes has been used as a novel physico-chemical environment to develop a more direct way of obtaining reliable values for the hydration numbers of cations. Simultaneous cyclic voltammetry and electrochemical quartz crystal microbalance technique was used to determine the amount of charge inserted and the total mass change during the reduction process in a polypyrrole film. From these values, the number of water molecules accompanying each cation was evaluated. The number of water molecules entering the polymer during the initial part of the first reduction was found to be constant and independent of the concentration of the electrolyte below ∼1 M. This well-defined value can be considered as the primary membrane hydration number of the cation involved in the reduction process. The goal was to investigate both the effects of cation size and of cation charge. The membrane hydration number values obtained by this simple and direct method for a number of cations are: Li + : 5:5 - 5:3; Na + : 4:5 - 4:3;K + : 2:3 - 2:5; Rb + : 0:9 - 0:8; Cs + : ∼ 0;Mg 2+ : 10:4 - 10:6; Ca 2+ : 7:9 - 8:1; Sr 2+ : 5:7 - 6:1; Ba 2+ : 3:0 - 3:1; Y 3+ : 13:6 - 13:8; La 3+ : 9:0 - 9:1: The hydration number for all of these cations seems to follow the same simple relation.

The study investigated the adsorption and bioavailability characteristics of traffic generated metals common to urban land uses, in road deposited solids particles. To validate the outcomes derived from the analysis of field samples, adsorption and desorption experiments were undertaken. The analysis of field samples revealed that metals are selectively adsorbed to different charge sites on solids. Zinc, copper, lead and nickel are adsorbed preferentially to oxides of manganese, iron and aluminium. Lead is adsorbed to organic matter through chemisorption. Cadmium and chromium form weak bonding through cation exchange with most of the particle sizes. Adsorption and desorption experiments revealed that at high metal concentrations, chromium, copper and lead form relatively strong bonds with solids particles while zinc is adsorbed through cation exchange with high likelihood of being released back into solution. Outcomes from this study provide specific guidance for the removal of metals from stormwater based on solids removal. © 2014 Elsevier Ltd.

The study investigated the factors influencing e-learning adoption behavior of instructors of a public university in Sri Lanka. The analysis of various models used to study the adoption behavior reveals that cultural factors were neglected. Therefore an e-learning adoption model was proposed considering cultural factors and the model was tested among instructors. The findings of this research have significant effects on the suitability of adopting an e-learning system at this university. However it is recommended that this study should be extended to include instructors belonging to multi-ethnic groups in all universities in Sri Lanka. © (2013) Trans Tech Publications, Switzerland.

Universities and other educational institutions around the world are increasingly using e-learning technology to more efficiently and effectively deliver the education to their students. Successful implementation of e-learning system is determined by the acceptance of such system by students. Therefore this study was undertaken to explore the factors that influence the intention of students to adopt e-learning at the South Eastern University of Sri Lanka (SEUSL) and the investigation was carried out by using UTAUT model. It was found that, performance expectancy, effect expectancy and facilitation conditions are the important factors, that are influencing students' intention to adopt e-learning, and the results are contributory for the development of a strategy for implementing e-learning system at this university. It was also found that, both, the university and students are capable of adopting e-learning system. © 2013 Springer International Publishing.

Mud blocks are one of the oldest and most widely used building materials and dates back to 8000 Before Christ. The development of a new type of soil cement block called Mud block with 10% cement with low fine content using pouring method is the main purpose of this research. 10% and 15% of fine content were defined as the low fine content in this research as it was a part of the continuous research series. Initially the optimum gravel and sand content to achieve high strength was determined and it was concluded that 30% of gravel content was the optimum for both fine content. Then the moisture content corresponding to the pouring stage of soil mixture consists of optimum gravel, sand and 10% and 15% of fine content was found and the values were an average of 18% and 20% respectively. Pouring stage was found when the soli mixture behaves as high consistency liquid. Six blocks were cast each fine content; three blocks were used to determine the dry compressive strength and other three were used to determine the wet compressive strength. Length, width and height of one block were 325mm, 200mm and 125mm respectively and weight was about 15kg. Dry and wet compressive strength achieved satisfies the minimum strength requirement of block used for the construction of load bearing wall according to the SLS 1382. Therefore these blocks can be used in load bearing wall construction. The strength achieved is fairly high than the minimum requirements. So for the future study of Mud blocks, it is recommended to reduce the cement content for casting the Mud blocks. © 2016 IEEE.

Development of a four hazard-specific toolkit (drought, flood, landslide and chronic kidney diseases of unknown aetiology) for needs and vulnerability assessment in the water, sanitation and hygiene (WASH) sector included community consultations with district, divisional and community stakeholders in four selected districts of Sri Lanka, which are highly prone to the respective hazards. Existing global WASH tools such as sphere and global WASH cluster indicators are contextualized, and the toolkit covers three different displacement scenarios: no displacement, temporary displacement (short and medium term), and camp-based displacement. This toolkit focuses on four key sections of WASH: water supply, sanitation, waste management and control, and hygiene practices and promotion. The toolkit consists of a set of indicators in the areas of WASH that are relevant to the selected scenario in the Sri Lankan context for the specific hazard, a checklist for initial and rapid assessment before and after disasters, and some guide notes for the field works. © IWA Publishing 2016.

Objective: To investigate the clinical features of chikungunya fever (CHIKF) outbreak in Sri Lanka in 2006 and to estimate the relative risk for CHIKF for various demographic factors. Methods: A total of 885 individuals belonging to 200 families were studied individually for surveillance of this disease, symptoms, contraction order within the family and means of treatments. Relative risks for CHIKF for demographic characters such as gender, age and educational levels were estimated. The associations of symptoms with age and gender were also studied. Results: The estimated surveillance of CHIKF in the studied population was 89.2%. The duration of suffering due to this disease was 50.9 d (95% CI, 47.3, 53.9 d) with fever for 3.9 d (95% CI, 3.7, 4.1 d). 93% of the CHIKF patients felt at least one type of joint pain and 8% felt joint swellings. Rash was observed in 15.1% of the patients. Buccal bleeding and mouth ulcer were observed in 1.5% and 9.3% respectively. About 22.7% of the CHIKF patients had vomiting. Female had 1.48 folder higher relative risk for CHIKF infection. The duration suffered due to CHIKF, duration of fever and contraction order within family were highly associated with age (P<0.000). Female patients had more than one folder higher relative risks for the symptoms such as rash, vomiting, buccal bleeding and mouth ulcer (P<0.000). Conclusions: The surveillance of CHIKF in Sri Lanka was a severe outbreak which infected much on female and caused more suffering on aged population. The symptoms such as rash, bleeding from mucosa, mouth ulcer and vomiting were highly associated with gender. The reasons for these observations need to be further explored. © 2014 Asian Pacific Tropical Medicine Press.
