This study was conducted to develop a composite flour based pasta enriched with a probiotic: Bacillus coagulans GBI-30, 6086 and focus to select the appropriate flour blend, to determine the cooking quality of pasta, the viability of the probiotic and to determine the survival (%) of probiotic after cooking. Commercially available pasta was used as a control. Physicochemical properties (color and texture, water activity and cooking qualities: optimum cooking time, cooking lose, water absorption, volume expansion), proximate composition (moisture - 4.05 %, crude protein -13.00 %, crude fat - 5.66 %, ash - 3.45 %, crude fiber - 5.45 % and carbohydrates - 72.44 %), viability of probiotic Bacillus coagulans GBI-30, 6086 were determined during storage of one month at 30±1°C. Sensory evaluation was conducted with 30 semi-trained panelists using 7 point hedonic scale and color, appearance, odor, flavor, chewing properties, and overall acceptability were evaluated. The highest acceptability was achieved by pasta formulated from wheat (50 %), corn (20 %), semolina (20%) and pumpkin seed (10%) flours. Color, flavor, sensation of starch between teeth and tenderness of the developed pasta were significantly different (p>0.05) from commercially available pasta. Hence, this flour blend was selected for further analysis. Optimum cooking time was 10 minutes. The water activity of pasta was ranged between 0.30-0.35 and survival (%) of probiotic after cooking decreased from 91.7 % to 87.5 % during storage period. Viability of the probiotic has achieved the daily requirement of one billion colony forming units per serving (1×109 CFUs/serv) and the same was monitored for a period of one month.

Social innovation is defined as an institutional change leading to the emergence of new routines. Providing affordable housing to low-income communities is a challenge faced by many developing countries. Mud-Concrete (MC) technology is a promising material solution recently developed to achieve sustainable goals. This paper discusses a novel finding in Engineering that could be applied to resolve a social issue integrating with architectural norms.

Civilization cannot exist without science, technology and innovation. However, there is much evidence from world history that science and technology alone cannot take a civilization forward but need support with strong socio-cultural aspects. Sri Lanka, a country with a robust evidence based history has well proven the concrete facets of strong sociocultural aspects coupled with science/ technology. However, this strength which was the stem of the success of our motherland was drained out for many decades now and that itself was a reason for poor development of the country. Hence, it is obvious that delinking of both R & D Innovation and social Innovation is a must towards the development of Sri Lanka.

Flooring is considered to be as one of the main components of a building, it is important to analyze the positive and the negative properties of flooring materials with respect to sustainability. Once identify the negative properties, there is a need to investigate the possibility of introducing a new flooring material to overcome existing disadvantages. The natural material, ‘soil/mud’, has been used in the construction industry for thousands of years. There are numerous researches worldwide as well in Sri Lanka, interrelated to soil as a construction material. However, soils used as flooring material have not yet been fully investigated. Hence, this study was focused to have a better understanding of the possibility to use soil as a flooring material. This paper presents the preliminary experimental results. Soil extracted from the ground was developed to reach soil compositions with gravel (sieve size 4.75mm≤gravel≤20 mm) 35%, sand (sieve size 0.425mm≤sand≤4.75 mm) 60% and fine particle (≤sieve size 0.425 mm) 5% which was identified as the best proportion for mud concrete in previous researches. The samples were cast by mixing of developed soil with 18% cement. Samples were tested in several aspects. According to the primary experimental results, it can be concluded that there is a possibility to use soil as flooring material.

Thalassaemia is a chronic, genetically inherited, autosomal recessive blood disease. Thalassaemia patients suffer serious illnesses with socio-economic problems and need treatments throughout their lifetime. The estimated number of Thalassaemia homozygote patients in Sri Lanka is 2000 and Beta Thalassaemia carriers count is 2.2% of the population. The objectives of this study are to identify the present knowledge and attitude of patients and their families about thalassaemia, identify the carrier’s awareness and interest in the screening test and evaluate the effectiveness of the awareness programs. This research was conducted in the National Thalassaemia Centre in Kurunegala and was a community-based cross-sectional study. Data collection tools were structured interviews, observation method and literature sources. Twenty-five percent from each study population of different ages of patients, fifty parents, and fifty carriers in was the study sample. Patients below 12 years think that they need a bone marrow transplantation unit and adult patients believe correct blood transfusions and iron chelation can manage the disease positively. This knowledge was mostly given by the hospital and the contribution of mass media is slight. Carriers have a relatively better awareness of their condition. But their relatives are impassive about screening tests because they have fear and shame about the disease and carrier condition. People think that there is no change, positive or otherwise in the population with awareness programs. The major reason is because awareness does not reach the correct persons effectively. A detailed clinical and social knowledge of the disease should be included in the mass media communications and school syllabus.

Micronutrient deficiencies have been identified as a key issue regarding human health in many parts of the world. This study describes how the micronutrient content of rice can be improved with a modification to rice parboiling. Two paddy varieties (BG 352 and BG 358, respectively) initially tested for water uptake during hot soaking (70 ºC) under vacuum (- 0.6 bar), showed significantly (P<0.05) higher water uptake (28.5% and 26.15%, respectively) than that of non-vacuumed conditions (25.24% and 25.45% respectively), exhibiting the effectiveness of water diffusion into the rice grains through the cleared pores under vacuum. Hot soaking (70ºC) in 400 ppm solutions (Fe2+ or Zn2+) under vacuum (-0.6 bar) during the first hour, followed by 2.5 h under atmospheric pressure exhibited the optimum fortification (Fe2+: 46.59±0.37 ppm and Zn2+: 67.24±1.36 ppm) with a greater significance (P<0.05) compared to the controls (Fe2+: 38.84±0.62 ppm and Zn2+: 52.55±0.55 ppm) complying the World Food Program specifications for iron and zinc fortified rice, (40-48 mg/kg and 60-72 mg/kg respectively). This finding was further confirmed by the XRF images which showed fortificants distribution in the endosperm. There were no significant (P>0.05) differences among both Fe2+ and Zn2+ contents in fortified rice after washing (Fe2+: 44.31±1.2 ppm and Zn2+: 66.64±0.6 ppm), confirming their greater retention. Scanning Electron Microscope images proved that the rice kernel has porous areas which may facilitate water uptake into the middle parts of the endosperm during soaking. This technology has obtained international patent and is being used for commercial production of fortified rice.
