The brittle structural inventory of southern and southwestern Sri Lanka has been studied by kinematic, mineralogical and thermochronological techniques. Thermochronological analyses of faults comprise apatite and zircon fission track (FT) data and apatite (U-Th-Sm)/He ages from fault planes and undisturbed host rocks, and range between ∼65 and ∼230 Ma. The ages of both settings are undistinguishable for topographic altitudes below ∼100 m, while fault planes from higher elevations are significantly younger than the corresponding host rocks. Thermal history modeling and qualitative interpretation of the thermochronological data identify at least five episodes of thermal overprint associated with faulting activity occurring at 159 ± 18, 144 ± 14, 120 ± 10, 94 ± 8, and 70 ± 10 Ma. The kinematic, mineralogical and thermochronological data collectively show that Sri Lanka was subjected to major N-S oriented extension subsequent to the Gondwana breakup. The resulting brittle structures exert primary control on the island's geomorphology, especially on the Southern Escarpment of the Sri Lankan Highlands. © 2012. American Geophysical Union.

This study was conducted at Uswetakeiyawa on the southwestern part of Sri Lanka. Twenty-two families, 42 genera and 52 species were recorded from the sandy shore vegetation. Approximately 3.8 % (2 species) were found to be endemic and 67.3 % (35 species) were found to be of medicinal importance. Ipomea pes-capre and Spinifex littoreus were the most abundant species at the study site. The average value for all the zone combinations was β = 0.693, and the highest similarity value was ISj = 0.276, corresponding to two non-contiguous zones. The results show that a variation in plant diversity is to be found across the gradient. The typical zoning nature of the sandy shore vegetation has been disturbed due to on-going development in Uswetakeiyawa. New policy decisions should be taken to restrict development activities in Uswetakeiyawa in order to protect the sandy shore vegetation. © 2016 Springer Science+Business Media Dordrecht

Consumption of un-pasteurized fruit juices has increased in recent years due to their freshness and other attractive characters. Contamination of those by pathogenic microorganisms is considered as one of the major problems. Organic acid treatments, such as malic acid treatment, are used to control these contaminations. Am of this study was to evaluate the antimicrobial activity of malic acid against Listeria monocytogenes, Salmonella enteritidis and Escherichia coli in Mango, Pineapple and papaya juices. Minimal Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) of malic acid against those bacteria were evaluated for all tested fruit juices which were stored at 5, 20 and 35°C. Antibacterial effect of malic acid was observed against all tested bacteria under all tested conhtions. The antibacterial activity was depended upon the type of bacteria, type of fruit juice and storage conhtions. Antibacterial effect was higher in high temperature storage than low temperature storage. High concentration of malic acid was needed for Papaya juice compared to other fruit juices to reduce microbial population by a same amount. E. coli was found to be more resistant to antimicrobial activity of malic acid compared to the other two bacteria. Accorhng to the results of this study, E. coli can be recommended as a test bacterium in testing organic acids to be used as food preservatives. Further, these tests should be carried out in refrigerated temperature to find out more effective organic acids, as the lowest antibacterial activity of malic acid was observed at 5°C in this study. © 2013 Academic Journals Inc.

This research was conducted to study the male and female farmers' contribution to cultivation and use of underutilised crops in Monergala district of Sri Lanka. Application of a quantitative research method is the distinguishing feature of this study. A field survey was conducted using a sample of 120 farmers with the help of pre-tested questionnaire to collect the data. Descriptive statistics and two sample t-tests were used to analyse the data. According to the results, male farmers are specially engaged in such agricultural practices as land preparation, protection of farmlands from wild animals and marketing of underutilised crops, while the female farmers are specially engaged in other important agricultural practices such as planting, weeding and food preparation at home. Nevertheless, both male and female farmers contribute alike to some agricultural practices. Although male farmers are significantly contributing to the underutilised crop cultivation, as a whole, female farmers' contribution is higher. Copyright © 2016 Inderscience Enterprises Ltd.

In the present study interaction between three lactic acid bacteria species and three food borne pathogenic bacteria species were studied. The objective of the study was to determine the effect of those interactions to the antimicrobial compound producing ability of lactic acid bacteria. Using the three lactic acid bacteria namely, Lacto coccus lactis, Lactobacillus acidophilus and Lactobacillus casei and three pathogenic bacteria namely, Salmonella enterica, Escherichia coli and Listeria monocytogenes 56 different culture combinations were prepared and grown in a medium invented by de Man, Rogosa and Sharpe (MRS) broth. Then Cell Free Filtrates (CFF) containing antimicrobial compounds were obtained from all those cultures and tested for antimicrobial activity against the three pathogenic microorganisms. All Cell Free Filtrates (CFF) were found to be having antibiotic activity against tested three pathogenic bacteria. Antibiotic activity of Cell Free Filtrates (CFF) obtained from cultures contained both lactic acid bacteria and some pathogenic bacteria were significantly higher than cultures contained only lactic acid bacteria. However, this stimulating effect of pathogenic bacteria on antimicrobial compound production by lactic acid bacteria was different for different pathogenic bacteria. Stimulation by Escherichia coli was not observed and some times Escherichia coli shown to be reducing the antimicrobial compound production. Antibiotic activity was found to be higher in mixed cultures of lactic acid bacteria compared to individual cultures. Results of this study confirm the importance of using mixed cultures and effective stimulant bacteria in antimicrobial compound production by lactic acid bacteria. © 2012 Academic Journals Inc.

Purpose - The present study was carried out with the intention of examining what type of instruction applications and help tools have been used to serve clientele via academic library websites and web pages, and how Sri Lankan academic libraries instruct and help users via their library websites and web pages. Design/methodology/approach - A sample study comprised only 14 academic library websites and web pages out of 223, which were accessible and necessarily presented instruction applications and help tools. Two coding sheets were prepared separately for instruction and help to include classified data, and then the frequency counted from each category by browsing the sample recorded in the coders for analysis. Findings - The results confirmed that the quality of academic library websites in Sri Lanka in providing online instruction and help was dependent on different variables. The development of above online services remains in its infancy. Most important instruction applications and help tools have not been utilized by the majority of websites in academic libraries. Inaccessibility of such services via the library web reflects not only their malfunction in online instruction and help, but also onsite services of some areas in academic libraries. Research limitations/implications - Nonexistence of websites or web pages and lack of enough information in library websites caused the exclusion of most of the libraries in the country from inclusion in the sample; this in turn affected this study by limiting it to academic libraries only. Practical implications - The majority of recommendations originated from the study can be generalized for both web and online service development of any type of library in Sri Lanka. Originality/value - The deficiency of research on library websites in Sri Lanka provides no clear image regarding the existing situation of online library services. Thus this study contributes towards addressing this gap in the literature and features distinctiveness within the available literature. Copyright © 2012 Emerald Group Publishing Limited.

There is a growing trend towards the production of ready to use multifunctional foods which has nutritional and medicinal value as well as good sensory properties. On the other hands, microbial safety of those foods is a major concern in food industry. Treatments used to ensure microbial safety of foods can affect the medicinal, nutritional and sensory properties of food. Aim of this study was to evaluate the affect of two such treatments namely UV irradiation and thermal processing on some important properties of ready to serve tropical almond drink. Prepared tropical almond ready to serve drink samples were subjected to UV irradiation and three different heat treatments. Then microbial stability, antioxidant activity and sensory properties of those treated samples were evaluated comparatively to non-treated samples. Two properties tested in this study, namely microbial stability and antioxidant activity was found to be affected by both treatments tested. Sensory properties of the product were found to be affected only by thermal processing. Compared to non-treated and thermal processed tropical almond ready to serve drinks, UV irradiated tropical almond ready to serve drinks were found to be microbiologic ally more safe and with preserved sensory properties. Hence, UV irradiation was identified as a suitable method to treat tropical almond ready to serve drinks to ensure microbial safety over thermal processing. © 2012 Academic Journals Inc.

Mitigation and Adaptation Strategies for Global Change | Year: 2013

The vulnerability of smallholder farmers to climate change and variability is increasingly rising. As agriculture is the only source of income for most of them, agricultural adaptation with respect to climate change is vital for their sustenance and to ensure food security. In order to develop appropriate strategies and institutional responses, it is necessary to have a clear understanding of the farmers' perception of climate change, actual adaptations at farm-level and what factors drive and constrain their decision to adapt. Thus, this study investigates the farm-level adaptation to climate change based on the case of a farming community in Sri Lanka. The findings revealed that farmers' perceived the ongoing climate change based on their experiences. Majority of them adopted measures to address climate change and variability. These adaptation measures can be categorised into five groups, such as crop management, land management, irrigation management, income diversification, and rituals. The results showed that management of non-climatic factors was an important strategy to enhance farmers' adaptation, particularly in a resource-constrained smallholder farming context. The results of regression analysis indicated that human cognition was an important determinant of climate change adaptation. Social networks were also found to significantly influence adaptation. The study also revealed that social barriers, such as cognitive and normative factors, are equally important as other economic barriers to adaptation. While formulating and implementing the adaptation strategies, this study underscored the importance of understanding socio-economic, cognitive and normative aspects of the local communities. © 2012 Springer Science+Business Media B.V.

The concept of ontologies has widely been used in various applications including email filtering and electronic news classification. It can be also used for the classification of digital documents in a library. Advancing the accuracy of classification is the main purpose of using ontologies for classification. Documents may be difficult to understand due to the vague terms used in the text. However, since ontologies represent the semantic relationships of the terms, they can be used to correctly identify the subject of a document. This study made an attempt to improve the classification accuracy of an automatic text classification system by using an ontology.Classification results given by the automatic system with and without integrating the ontology were used to evaluate the impact of the ontology for automatic classification. Results showed that 32.76% more documents and 25% more subjects were correctly classified by the ontology based system than the system prior to use of ontology. © 2014 National Institute of Science Communication and Information Resources (NISCAIR).

Turtles at the Rekawa sanctuary in Sri Lanka are under threat due to ongoing illegal activities. This study estimates the entrance fee that can be charged to visitors for 'turtle watching' to ascertain whether revenues from such fees can be used to compensate fishermen and reduce such illegal activities. We carried out a contingent valuation study to examine the foreign and local visitors' willingness to pay (WTP) for turtle conservation under two different management scenarios. The estimated mean WTP per visit for local visitors was LKR 93 (USD 0.73) and LKR 143 (USD 1.12) for Scenarios 1 and 2, respectively, while the mean WTP of foreign visitors was USD 15 and USD 19 for Scenarios 1 and 2, respectively. These results, which suggest potentially huge gains in revenue, can be used to re-design entry fees for the Rekawa sanctuary and secure the cooperation of low-income fishermen in turtle conservation. © 2015 Elsevier Ltd.
