    Background: Cytogenetic analysis is a valuable investigation in the diagnostic work up of children with suspected chromosomal disorders. The objective of this study was to describe the prevalence of various types of chromosomal abnormalities in Sri Lankan children undergoing cytogenetic analysis. Methods: Cytogenetic reports of 1554 consecutive children with suspected chromosomal disorders who underwent karyotyping in two genetic centers in Sri Lanka from January 2006 to December 2011 were reviewed retrospectively. Results: A total of 1548 children were successfully karyotyped. Abnormal karyotypes were found in 783 (50.6%) children. Numerical and structural abnormalities accounted for 90.8% and 9.2%, respectively. Down syndrome was the commonest aneuploidy identifi ed. Other various autosomal and sex chromosomal aneuploidies as well as micro-deletion syndromes were also detected. Conclusions: The prevalence of chromosomal abnormalities in Sri Lankan children undergoing cytogenetic analysis for suspected chromosomal disorders was relatively higher than that in Caucasian and other Asian populations.

    Full Text Available Abstract Background Food Frequency Questionnaires (FFQs are commonly used in epidemiologic studies to assess long-term nutritional exposure. Because of wide variations in dietary habits in different countries, a FFQ must be developed to suit the specific population. Sri Lanka is undergoing nutritional transition and diet-related chronic diseases are emerging as an important health problem. Currently, no FFQ has been developed for Sri Lankan adults. In this study, we developed a FFQ to assess the regular dietary intake of Sri Lankan adults. Methods A nationally representative sample of 600 adults was selected by a multi-stage random cluster sampling technique and dietary intake was assessed by random 24-h dietary recall. Nutrient analysis of the FFQ required the selection of foods, development of recipes and application of these to cooked foods to develop a nutrient database. We constructed a comprehensive food list with the units of measurement. A stepwise regression method was used to identify foods contributing to a cumulative 90% of variance to total energy and macronutrients. In addition, a series of photographs were included. Results We obtained dietary data from 482 participants and 312 different food items were recorded. Nutritionists grouped similar food items which resulted in a total of 178 items. After performing step-wise multiple regression, 93 foods explained 90% of the variance for total energy intake, carbohydrates, protein, total fat and dietary fibre. Finally, 90 food items and 12 photographs were selected. Conclusion We developed a FFQ and the related nutrient composition database for Sri Lankan adults. Culturally specific dietary tools are central to capturing the role of diet in risk for chronic disease in Sri Lanka. The next step will involve the verification of FFQ reproducibility and validity.

    Chronic kidney disease (CKD) is common and independently associated with cardiovascular disease (CVD). Arterial stiffness contributes to CVD risk in CKD. In many developing countries a considerable proportion of CKD remains unexplained, termed CKDu. We assessed arterial stiffness in subjects with Sri Lankan CKDu, in matched controls without CKD and in those with defined CKD. Aortic blood pressure (BP), pulse wave velocity (PWV) and augmentation index (AIx) were assessed in 130 subjects (50 with CKDu, 45 with CKD and 35 without CKD) using the validated TensioMed™ Arteriograph monitor. Brachial and aortic BP was lower in controls than in CKDu and CKD subjects but no different between CKDu and CKD. Controls had a lower PWV compared to subjects with CKDu and CKD. Despite equivalent BP and renal dysfunction, CKDu subjects had a lower PWV than those with CKD (8.7 ± 1.5 vs. 9.9 ± 2.2 m/s, p groups (controls vs. CKDu vs. CKD: 6.7 ± 0.9 vs. 8.7 ± 1.5 vs. 10.4 ± 1.5 m/s, p < 0.001 for all). Sri Lankan CKDu is associated with less arterial stiffening than defined causes of CKD. Whether this translates to lower cardiovascular morbidity and mortality long term is unclear and should be the focus of future studies.

    The General Medical Council of the UK, advocates that by the end of their undergraduate course, medical students should be proficient in communicating with patients. However, the attitude of some medical students toward formal training in communication skills seems lukewarm. Although several studies on assessing attitudes of medical students on learning communication skills have been carried out in Europe and America, Asian studies are very few and literature in the Sri Lankan context is lacking. To explore the attitudes of first to fourth year medical students of the Faculty of Medicine, University of Peradeniya (FOMUP), Sri Lanka on learning communication skills and to identify possible factors that may influence student attitudes. A total of 675 students from year 1 to 4 of the FOMUP were asked to complete a modified version of the Communication Skills Attitude Scale. Items of its positive attitude scale (PAS) were analyzed together while negative items were considered individually. Response rates ranged from 70% to 98% for the various year groups. There were no significant differences between the PAS for males and females and for those exposed to formal training and those who were not. The junior students scored significantly higher on the PAS than seniors. Most students of all the groups disagreed with the item "I don't see why I should learn communication skills". Approximately one-quarter of the students of each group endorsed the statement "Nobody is going to fail their medical degree for having poor communication skills". Out of the students who have undergone formal communication training, almost one-third agreed that they find it difficult to take communication skills learning seriously. Although medical students seem to have realized the importance of communication skills training for the practice of medicine, a significant minority have reservations on attending such sessions. Sri Lanka faculty will need to make a concerted effort to change this

    Full Text Available Today in the software industry, software application development is a major area which is developing rapidly. Also most of the software is developing as mobile application because due to the busy life style, most of the people in the world prefer to use easy methods to do their day-today work. The application testing for mobile device is an emerging research area that most commonly faces challenges. Varieties of mobile devices need to test the application; unique features of mobile devices, limited bandwidth, and unreliability of wireless networks are most common issues faces by the mobile application testing. Also the traditional guidelines and methods used in methodologies which are used to test desktop applications may not be applicable to a mobile environment. The contribution of this research paper is to identify the issues that are faces when testing software applications for mobile devices in Sri Lankan software development industry through the interviews, questionnaire from the industry people and analysing of the gathered data. The paper includes an overview of existing problems in mobile application testing and major research questions that have been investigated. So this research paper will helpful for the upcoming mobile application developers and further researches about mobile application testing.

    Trypanosoma theileri is a hemoprotozoan parasite that infects various ruminant species. We investigated the epidemiology of this parasite among cattle and water buffalo populations bred in Sri Lanka, using a diagnostic PCR assay based on the cathepsin L-like protein (CATL) gene. Blood DNA samples sourced from cattle (n=316) and water buffaloes (n=320) bred in different geographical areas of Sri Lanka were PCR screened for T. theileri. Parasite DNA was detected in cattle and water buffaloes alike in all the sampling locations. The overall T. theileri-positive rate was higher in water buffaloes (15.9%) than in cattle (7.6%). Subsequently, PCR amplicons were sequenced and the partial CATL sequences were phylogenetically analyzed. The identity values for the CATL gene were 89.6-99.7% among the cattle-derived sequences, compared with values of 90.7-100% for the buffalo-derived sequences. However, the cattle-derived sequences shared 88.2-100% identity values with those from buffaloes. In the phylogenetic tree, the Sri Lankan CATL gene sequences fell into two major clades (TthI and TthII), both of which contain CATL sequences from several other countries. Although most of the CATL sequences from Sri Lankan cattle and buffaloes clustered independently, two buffalo-derived sequences were observed to be closely related to those of the Sri Lankan cattle. Furthermore, a Sri Lankan buffalo sequence clustered with CATL gene sequences from Brazilian buffalo and Thai cattle. In addition to reporting the first PCR-based survey of T. theileri among Sri Lankan-bred cattle and water buffaloes, the present study found that some of the CATL gene fragments sourced from water buffaloes shared similarity with those determined from cattle in this country.

    AIM: To determine if inflammatory bowel disease (IBD) is a risk factor for osteoporosis in adult Sri Lankans. METHODS: We identified eligible subjects from among consecutive patients diagnosed with IBD who attended our outpatient clinic. We included only patients aged between 20 and 70 years. Patients who were pregnant, had significant comorbidity, or were on calcium supplements or treatment for osteoporosis within the past 6 mo, were excluded. Healthy, age- and sex-matched controls were also recruited, in a control to patient ratio of 3:1. Both groups were screened for osteoporosis using peripheral dual energy X-ray absorptiometry scanning. RESULTS: The study population consisted of 111 IBD patients (male:female = 43:68; mean age 42.5 years) and 333 controls (male:female = 129:204; mean age 43.8 years). The occurrence of osteoporosis among IBD patients (13.5%) was significantly higher than among controls (4.5%) ( P = 0.001). The frequency of osteoporosis was not significantly different between ulcerative colitis (14.45%) and Crohn's disease (10.7%). However, on multivariate analysis, only age ( P = 0.001), menopause ( P = 0.024) and use of systemic steroids ( P < 0.001) were found to be associated independently with the occurrence of osteoporosis, while IBD, severity of disease, number of relapses, duration of illness or treatment other than systemic steroids were not. CONCLUSION: IBD does not appear to be an independent risk factor for the occurrence of osteoporosis in this population. However, the use of systemic steroids was a risk factor.

Different concentrations of black tea brew (BTB [84 mg/ ml (equivalent to 1.5 cups, 167 mg/ ml (equivalent to 3 cups, 501 mg/ ml (equivalent to 9 cups or 1336 mg/ ml (equivalent to 24 cups], or a high concentration (equivalent to 9 cups of green tea brew (GTB of Chinese and Japanese types or reference drug, toperamide (10 mg/ kg were orally administered to different groups of mice (N = 9-12/group and were subjected to two antidiarrhoeal tests: normal defecation test and castor oil-induced diarrhoea test. The results show that BTB of Sri Lankan Dust grade tea dose-dependently and markedly decreased the number of faecal boluses produced in the normal defecation test and improved the severity of the diarroheal condition in the castor oil-induced diarrhoea test. However, the antidiarrhoeal effect of BTB was superior to Japanese type of GTB and inferior to loperamide. BTB also prolonged the gastrointestinal transit time, impaired intestinal fluid secretion, increased intestinal fluid absorption and reduced in vitro nitric oxide production. It is concluded that Sri Lankan black tea possesses marked antidiarrhoeal activity supporting the folkloric claim that Sri Lankan black tea is a good remedy for acute non specific diarrhoea.

    Directory of Open Access Journals (Sweden)

    Jeyaseelan Gnanaseelan

    2015-07-01

    Full Text Available The metaphors used in the Sri Lankan English newspaper editorials during the peace talk time (2001-2007 commenting on the international intervention in the Sri Lankan ethnic conflict reveal community based ideological and attitudinal positions of the newspapers published in Sri Lanka. Metaphors literally contribute to our understanding of reality. The frames and scripts used for legitimization and de-legitimization of the issues related to international intervention and facilitation in the peace talk, peace process and monitoring the ceasefire bring out certain realities comfortable to certain people, groups or communities. The binary positions projected in the editorial discourse are identified. Discourse constitutes power in constructing ideational, textual and interpersonal constructs which are ideological. It can transmit and even legitimize power in society. During the peace talk time, the editorials are expected to develop constructive discourse on conflict intervention and resolution to make a positive impact on legislative changes but they display ‘ethno-nationalist’ tendencies. The study analyzes whether the media has been a part of the problem or a part of the solution. Since newspaper and editorial discourses are the constructions of journalists and editors of the elites, the biased ideologies are “hidden or subtle in expressions and often revealed in mild forms”. This study takes up selected editorials of the Sri Lankan English newspapers which appeared mainly during the Memorandum of Understanding between the Sri Lankan government and the Liberation Tigers of Tamil Eezham during that period, to relate the discourse themes with rhetorical and metaphorical features.

    Students Involved in Rational Health Activities (SIRHA) is a group of Sri Lankan medical students dedicated to increasing awareness of rational health care. SIRHA has hosted a seminar on rational therapeutics for medical students. Clinicians and academicians discussed case histories of inappropriate drug treatment at the seminar. A panel organized by the International Advertisers Association addressed the levels of control needed for medical drug advertising. Another seminar focused on how to facilitate the provision of low cost quality drugs based on rational prescriptions to all Sri Lankans. The Director-General of Health Services, the Chairman of the State Pharmaceuticals Corporation, and other government officials discussed drug registration, tenders, local manufacture of drugs, quality assurance, distribution, and pricing. At the annual meeting of the Sri Lankan Medical Association, SIRHA members prepared a leaflet comparing statements on promotional material of pharmaceutical companies with the text of internationally recognized standard works of reference. Company representatives were at the meeting. The Medical Lobby for Appropriate Marketing addressed one of the promotional materials in an August 1993 international letter. SIRHA members have also targeted irrational and misleading advertising of health-related products in the mass media. They have succeeded in bringing about the withdrawal of a misleading ad with unsubstantiated claims by a multinational company operating in Sri Lanka. SIRHA has submitted a complaint to the People's Tribunal on pharmaceutical pricing, unethical promotion, and the availability of an irrationally large number of me-too drugs in Sri Lanka. The Tribunal found the complaint justified and recommended the adoption of regulations proposed by SIRHA. SIRHA continues to monitor pharmaceutical advertising practices in Sri Lanka. It has established good relations with local and international groups.

Three dose of black tea brew (BTB [84 mg/ml, equivalent to 1.5 cups; 168 mg/ml, equivalent to 3 cups; and 501 mg/ml, equivalent to 9 cups] were made using high grown unblend Dust grade No: 1 black tea samples and was orally administed to rats (n = 6-9/ dose/ test. The results showed that Sri Lankan BTB possesses marked and significant (P < 0.05 oral anti-inflammatory activity against both acute and chronic inflammation. This anti-inflammatory activity was dose-dependent in the carrageenan-induced paw oedema test and cotton pellet granuloma test. Further, in the carrageenan paw oedema model, the anti-inflammatory activity of BTB was almost identical to green tea brew of both Chinese and Japanese types. Further, the BTB had significant antihistamine activity (in terms of wheal test phagocytic cell migration inhibitory activity (in terms carrageenan-induced leucocyte peritoneal infiltration test, nitric oxide production inhibitory activity, antioxidant activity (DPPH method and prostaglandin synthesis inhibition activity (in terms of rat enteropooling test. It is concluded that Sri Lankan black tea has marked anti-inflammatory potential against both acute and chronic inflammation which is mediated via multiple mechanisms.

    Background Interpopulation differences in drug responses are well documented, and in some cases they correspond to differences in the frequency of associated genetic markers. Understanding the diversity of genetic markers associated with drug response across different global populations is essential to infer population rates of drug response or risk for adverse drug reactions, and to guide implementation of pharmacogenomic testing. Sri Lanka is a culturally and linguistically diverse nation, but little is known about the population genetics of the major Sri Lankan ethnic groups. The objective of this study was to investigate the diversity of pharmacogenomic variants in the major Sri Lankan ethnic groups. Methods We examined the allelic diversity of more than 7000 variants in genes involved in drug biotransformation and response in the three major ethnic populations of Sri Lanka (Sinhalese, Sri Lankan Tamils, and Moors), and compared them with other South Asian, South East Asian, and European populations using Wright’s Fixation Index, principal component analysis, and STRUCTURE analysis. Results We observed overall high levels of similarity within the Sri Lankan populations (median FST=0.0034), and between Sri Lankan and other South Asian populations (median FST=0.0064). Notably, we observed substantial differentiation between Sri Lankan and European populations for important pharmacogenomic variants related to warfarin (VKORC1 rs9923231) and clopidogrel (CYP2C19 rs4986893) response. Conclusion These data expand our understanding of the population structure of Sri Lanka, provide a resource for pharmacogenomic research, and have implications for the clinical use of genetic testing of pharmacogenomic variants in these populations.

    Education, especially higher education, is considered vital for maintaining national and individual competitiveness in the global knowledge economy. Following the introduction of its "Free Education Policy" as early as 1947, Sri Lanka is now the best performer in basic education in the South Asian region, with a remarkable record in terms of high literacy rates and the achievement of universal primary education. However, access to tertiary education is a bottleneck, due to an acute shortage of university places. In an attempt to address this problem, the government of Sri Lanka has invested heavily in information and communications technologies (ICTs) for distance education. Although this has resulted in some improvement, the authors of this article identify several barriers which are still impeding successful participation for the majority of Sri Lankans wanting to study at tertiary level. These impediments include the lack of infrastructure/resources, low English language proficiency, weak digital literacy, poor quality of materials and insufficient provision of student support. In the hope that future implementations of ICT-enabled education programmes can avoid repeating the mistakes identified by their research in this Sri Lankan case, the authors conclude their paper with a list of suggested policy options.

    The purpose of the present study was to evaluate the association between self-perception of body weight, weight loss approaches and measured body mass index (BMI) and waist circumference (WC) among Sri Lankan adults. A nationally representative sample of 600 adults aged ≥18 years was selected using a multi-stage random cluster sampling technique. An interviewer-administrated questionnaire was used to assess demographic characteristics, body weight perception, abdominal obesity perception and details of weight losing practices. Weight, height and waist circumference (WC) were measured and Asian anthropometric cut-offs for BMI and WC were applied. Body weight mis-perception was common among Sri Lankan adults. Two-thirds of overweight males and 44.7% females considered themselves as ‘about right weight’, moreover, 4.1% and 7.6% overweight men and women reported themselves as being ‘underweight’. Over one third of both male and female obese subjects perceived themselves as ‘about right weight’ or ‘underweight’. Nearly 32% of centrally obese men and women perceived that their WC is about right. People who perceived themselves as overweight or very overweight (n = 154) only 63.6% tried to lose weight (n = 98), and one quarter of adults sought advice from professionals (n = 39). Body weight misperception was common among underweight, healthy weight, overweight, and obese adults in Sri Lanka. Over 2/3 of overweight and 1/3 of obese Sri Lankan adults believe they are in right weight category or are under weight. © 2014 Asian Oceanian Association for the Study of Obesity .

    Full Text Available The aim of this study was to evaluate the diuretic potential of Sri Lankan black tea (Camellia sinensis L.. This was assessed in rats using high grown Dust grade No: 1 tea, which is consumed widely by the tea drinkers worldwide. Different doses of hot black tea brew (BTB (84, 167, 501 or 1336 mg/ml respectively equivalent to 1.5, 3, 9 and 24 cups were made and orally administered to previously starved (24 h but subsequently hydrated (with 15 ml of isotonic saline rats and their urinary output was monitored cumulatively at hourly intervals for 6h. The reference drug used was frusemide (13 mg/kg. The results showed that BTB induced significant (P < 0.05, mild to moderate and dose- dependent diuresis (starting from 167 mg/ml. This diuretic activity had a fairly rapid onset (within 2 h and relatively short duration of action (3 h. BTB also significantly (P < 0.05 increased the overall urinary frequency. Further, the diuretic activity of BTB was less potent to frusemide (by 45%. Decaffeination of black tea almost completely abolished the diuresis. The diuresis of the BTB was solely due to increased (by 55 % urinary Na + excretion (with no urinary K + loss. Further, the chronic daily administration of the BTB did not develop tolerance or induce toxicity (general, renal and hepatic. It is concluded that BTB made from Sri Lankan high grown Dust grade No :1 tea has safe, mild to moderate diuretic activity with rapid onset and relatively short duration of action. Further, this study supports the claim made by Sri Lankan indigenous physicians that it is a diuretic.

    Helicobacter pylori prevalence is decreasing globally and prevalence of non H. pylori gastric ulcers is increasing. The following study was conducted to assess the prevalence of H. pylori in benign gastric ulcers in a sample of Sri Lankan patients. This was a cross-sectional study of 59 dyspeptic patients with benign gastric ulcers. Multiple endoscopic gastric biopsies were obtained and histology, immunohistochemistry and polymerase chain reaction were performed for H. pylori detection. An immunochromatography assay was performed to detect blood anti H. pylori antibodies. Four (6.8%) were positive for H. pylori. Therefore, it is likely that most benign gastric ulcers are of non-H. pylori aetiology.

    Full Text Available It is imperative that Sri Lanka grasps the concepts of green jobs to meet the most vital but intricatechallenge of the 21st Century, which is the transformation to a sustainable and a low-carbon economy.Such a transformation or a paradigm shift, which can be gradual or rapid depending on the circumstances,will undoubtedly have a considerable positive effect on the way we produce and/or consume goods andservices. The speed at which this transformation would occur is likely to accelerate in the near future asthere is a trend of global transition from a traditional to a low-carbon economy, in order to attainsustainable economies. Such trends will help create an array of different forms of green jobs across manysectors, and most probably can become a catalyst for further development. The International LabourOrganization (ILO has defined green jobs as “Jobs created when they help in reducing the negativeenvironmental impacts ultimately leading to environmentally, economically and socially sustainableenterprises and economies”. Green jobs, in general, stand on two pillars: decent work and environmentalsustainability. Thus, green jobs can be defined as decent work that contributes to environmentalsustainability. In a broader sense decent work needs to address the core of international labour standardssuch as freedom of association and effective recognition of the right to collective bargaining, eliminationof all forms of forced or compulsory labour, effective abolition of child labour, elimination ofdiscrimination in respect of employment and occupation, occupational health and safety, etc. whilstaligning to laws applicable to Sri Lanka. Environmental sustainability addresses issues such as effectivelycombating climate change, pollution prevention and control, conservation of eco-systems and biodiversityetc. (ILO, 2007.

    It is well recognized that oral squamous cell carcinoma (OSCC) cases from Asia that are associated with betel quid chewing are phenotypically distinct to those from Western countries that are predominantly caused by smoking/drinking, but the molecular basis of these differences are largely unknown. The aim of this study is to examine gene expression, related carcinogenic pathways and molecular processes that might be responsible for the phenotypic heterogeneity of OSCC between UK and Sri Lankan population groups. We have compared the gene expression profiles of OSCCs and normal oral mucosal tissues from both Sri Lankan and UK individuals using Affymetrix gene expression arrays. The generated data was interrogated using significance analysis of microarrays and Ingenuity Pathway Analysis (IPA). The gene expression profiles of UK and Sri Lankan OSCC are similar in many respects to other oral cancer expression profiles reported in the literature and were mainly similar to each other. However, genes involved in tumor invasion, metastasis and recurrence were more obviously associated with UK tumors as opposed to those from Sri Lanka. The development of OSCCs in both UK and Sri Lankan populations appears largely mediated by similar biological pathways despite the differences related to race, ethnicity, lifestyle, and/or exposure to environmental carcinogens. However, IPA revealed a highly activated "Cell-mediated Immune Response" in Sri Lankan normal and tumor samples relative to UK cohorts. It seems likely, therefore, that any future attempts to personalize treatment for OSCC patients will need to be different in Western and Asian countries to reflect differences in gene expression and the immune status of the patients.

  16. The Middle Passage: Migration and Displacement of Sri Lankan Tamil Women of the Diaspora

    Directory of Open Access Journals (Sweden)

    Sivamohan Sumathy

    2010-01-01

    Full Text Available The article attempts to grapple with different facets of marginalisation produced by a specific type of Diasporic activity - as women, as Sri Lankan Tamils, and as participants that must negotiate a process that is at once transnational and postcolonial. Through the examination of different cultural modes of expression, novels, stories, and pamphlets, it attempts to answer as to how the Sri Lankan Tamil woman, away-from-home, makes sense of her world and how she sees it vis-a-vis her 'homeland'. Though displacement itself contains the liberatory potential, is this 'truth' of a better world often distorted by indirect and direct controls imposed by hegemonic West? Through the metaphor of the woman's body the author attempts to map the contours of identity-politics that are at play on trans-border women. By marking the different phases in the process of Tamil migration, she notes the change that has come about in the constitution of 'nationalist' identities, the role of transnational locations, and in the final phase, the reformulation of identity with changes in class. Of particular interest here is the continuation of the Tamil nation, and the role it plays in the re-production of the marginalisation of women. What way out is there then? For the author, there is a 'middle passage', one that re-negotiates the contours of her own body, and thus her nation, through her own modes of expression, not radically or transgressively, but less violently.

    Full Text Available Background : The main service provider for childhood immunization in Sri Lanka is the government sector. However, utilization of private sector for childhood immunization is increasing rapidly. Existing national immunization data does not routinely include statistics on private sector immunization delivery adequately. Objective : To estimate the proportion of children immunized in the private sector; describe socio-demographic characteristics of private sector users and compare these with government sector users. Materials and Methods : A community-based crosssectional descriptive study was conducted using a pre-tested interviewer-administered structured questionnaire. This was done in the Colombo municipal council area using the WHO 30 cluster methodology. The total number of households in the sample was 553. Results : Out of the 5,028 total immunizations reported in the present study, around one-third (2,544 was obtained through the private sector. Nineteen percent (104 of children were exclusively immunized from the private sector. The distribution of usual immunization provider was - government sector 72.3% (400 and private sector 27.7% (153. Significant differences were observed (P < 0.001 between private and government sector users with regard to family income, social class, ethnicity, religion and educational level of the mother. The age-appropriate immunization among the 12- to 23-month age group was 92.3% (144 in the government sector, whereas it was 95% (38 in the private sector. Among the 24- to 35-month age group, it was 91.7% (121 and 92.7% (76 respectively. The age-adjusted immunization coverage rates were almost same among the government and private sector users except for the measles vaccine, where the private sector users had significantly (P = 0.016 higher coverage. Conclusions :Utilization of private sector immunization services is high in the Colombo municipal council area.

    In Sri Lanka, over one in three women experience intimate partner violence (IPV) victimization in their lifetime, making it a serious public health concern. Adverse childhood experiences (ACEs) such as child abuse and neglect, witnessing domestic violence, parental separation, and bullying are also widespread. Studies in Western settings have shown positive associations between ACEs and IPV perpetration in adulthood, but few have examined this relationship in a non-Western context. In the present study, we examined the association of ACEs with IPV perpetration among Sri Lankan men surveyed for the UN Multi-Country Study on Men and Violence in Asia and the Pacific. We found statistically significant positive associations between the number of ACE categories (ACE score) and emotional, financial, physical, and sexual IPV perpetration among Sri Lankan men. We analyzed the contributions of each ACE category and found that childhood abuse was strongly associated with perpetration of IPV in adulthood, with sexual abuse associated with the greatest increase in odds of perpetration (Adjusted odds ratio 2.36; 95% confidence interval: 1.69, 3.30). Witnessing abuse of one’s mother was associated with the greatest increase in the odds of perpetrating physical IPV (AOR 1.82; 95% CI: 1.29, 2.58), while lack of a male parental figure was not associated with physical IPV perpetration (AOR 0.76; 95% CI: 0.53, 1.09). These findings support a social learning theory of IPV perpetration, in which children who are exposed to violence learn to perpetrate IPV in adulthood. They also suggest that in Sri Lanka, being raised in a female-headed household does not increase the risk of IPV perpetration in adulthood compared to being raised in a household with a male parental figure. The relationship between being raised in a female-headed household (the number of which increased dramatically during Sri Lanka’s recent civil war) and perpetration of IPV warrants further study.

    Full Text Available This study investigates the current teaching trends and practices in teaching oral English in rural Sinhala-medium schools in Sri Lanka and their relevance to the current theoretical, empirical, and pedagogical perspectives of second-language acquisition (SLA. The present study, which was conducted in two Sri Lankan Sinhala-medium rural schools, is a case study in which the classroom observation, interviewing of the participants, and videotaping of students’ interaction were included as data collection tools. The spoken data were analyzed using the Communicative Orientation of Language Teaching (COLT scheme designed by Fröhlich, Spada, and Allen, while the numerical data obtained from the structured speaking test (Cambridge Key English for Schools Test were analyzed using independent samples t test. The findings of the study indicate that the instructional method used by English teachers does not provide the learners with adequate input of the target language to improve their oral communication skills in rural school contexts. As a result, a majority of students from rural schools in Sri Lanka demonstrate a limited or a low proficiency level in oral communication in English. Therefore, possible reasons for the lack of greater awareness towards more communicative teaching are discussed, and suggestions for promoting changes in teaching English as a Foreign Language (EFL in rural school contexts are offered.

    The relative importance of various factors in the pathogenesis of angular cheilitis in a population of Sri Lankan adults was studied. Forty-nine patients with cheilitis were examined clinically and microbiologically. Only 5 of 49 patients were full denture wearers. The clinical presentation of the lesions could be categorized as mild (Type I), moderate (Type II) or severe (Type III) and the duration of the lesions ranged from 1 month to more than 4 yr. Hematologic investigations revealed 18 patients with low hemoglobin 8 of whom had hypochromic, microcytic anaemia. Pathogenic organisms were isolated from 59% of the lesions; Candida spp. in 24 patients and Staph. aureus in 11 patients. A significant positive relationship between commissural leukoplakia and an infective etiology of angles was noted. This study confirms the multifactorial etiology of angular cheilitis while highlighting the varied clinical presentation of the lesions in an Asian population.

    Full Text Available Abstract Background The variations of the circle of Willis (CW are clinically important as patients with effective collateral circulations have a lower risk of transient ischemic attack and stroke than those with ineffective collaterals. The aim of the present cadaveric study was to investigate the anatomical variations of the CW and to compare the frequency of prevalence of the different variations with previous autopsy studies as variations in the anatomy of the CW as a whole have not been studied in the Indian subcontinent. Methods The external diameter of all the arteries forming the CW in 225 normal Sri Lankan adult cadaver brains was measured using a calibrated grid to determine the prevalence in the variation in CW. Chisquared tests and a correspondence analysis were performed to compare the relative frequencies of prevalence of anatomical variations in the CW across 6 studies of diverse ethnic populations. Results We report 15 types of variations of CW out of 22 types previously described and one additional type: hypoplastic precommunicating part of the anterior cerebral arteries (A1 and contralateral posterior communicating arteries (PcoA 5(2%. Statistically significant differences (p Conclusion The present study reveals that there are significant variations in the CW among intra and inter ethnic groups (Caucasian, African and Asian: Iran and Sri Lanka dominant populations, and warrants further studies keeping the methods of measurements, data assessment, and the definitions of hypoplasia the same.

    Full Text Available Abstract Background Occupational injuries among flight attendants have not been given appropriate attention in Sri Lanka. The purpose of this study was to estimate the incidence of onboard injury among Sri Lankan flight attendants and to describe the determinants of onboard injury. Methods A descriptive cross-sectional study was carried out among Sri Lankan flight attendants. All flight attendants undergoing their annual health and first aid training were invited to participate. Flight attendants who flew continuously for a six-month period prior to data collection were included in the study sample. Recall history of injuries for a period of six months was recorded. Results The study sample consisted of 98 (30.4% male and 224 (69.6% female flight attendants. The mean age of the study sample was 31 years (SD = 8 and the average duration of service was 10 years (SD = 7. A total of 100 onboard falls, slips or trips in the previous six months were reported by 52 (16.1% respondents. Of the total sample, 128 (39.8% cabin crew members reported an injury in the six months preceding the study. This represents a total injury incidence of 795 per 1000 person per year. The leading causes of injury was pulling, pushing or lifting (60.2%. The commonest type of injuries were strains and sprains (52.3%. Turbulence related injuries were reported by 38 (29.7% flight attendants. The upper limbs (44.5% and the back (32% were the commonest sites affected. After controlling for other factors, female flight attendants had 2.9 times higher risk (95% CI 1.2–7.2 of sustaining and injury than males. Irrespective of sex, body weight less than 56 kilograms (OR 2.9, 95% CI 1.4–5.8 and less than seven years of on board experience (OR 10.5, 95% CI 3.6–31.0 were associated with higher risk of injury. Conclusion Work related injury is a major occupational hazard to flight attendants. Appropriate preventive strategies are required to minimize them.

  10. Evaluation of common type 2 diabetes risk variants in a South Asian population of Sri Lankan descent.

    Directory of Open Access Journals (Sweden)

    Neelam Hassanali

    Full Text Available Most studies seeking common variant associations with type 2 diabetes (T2D have focused on individuals of European ancestry. These discoveries need to be evaluated in other major ancestral groups, to understand ethnic differences in predisposition, and establish whether these contribute to variation in T2D prevalence and presentation. This study aims to establish whether common variants conferring T2D-risk in Europeans contribute to T2D-susceptibility in the South Asian population of Sri Lanka.Lead single nucleotide polymorphism (SNPs at 37 T2D-risk loci attaining genome-wide significance in Europeans were genotyped in 878 T2D cases and 1523 normoglycaemic controls from Sri Lanka. Association testing was performed by logistic regression adjusting for age and sex and by the Cochran-Mantel-Haenszel test after stratifying according to self-identified ethnolinguistic subgroup. A weighted genetic risk score was generated to examine the combined effect of these SNPs on T2D-risk in the Sri Lankan population.Of the 36 SNPs passing quality control, sixteen showed nominal (p<0.05 association in Sri Lankan samples, fifteen of those directionally-consistent with the original signal. Overall, these association findings were robust to analyses that accounted for membership of ethnolinguistic subgroups. Overall, the odds ratios for 31 of the 36 SNPs were directionally-consistent with those observed in Europeans (p = 3.2×10(-6. Allelic odds ratios and risk allele frequencies in Sri Lankan subjects were not systematically different to those reported in Europeans. Genetic risk score and risk of T2D were strongly related in Sri Lankans (per allele OR 1.10 [95%CI 1.08-1.13], p = 1.2×10(-17.Our data indicate that most T2D-risk variants identified in Europeans have similar effects in South Asians from Sri Lanka, and that systematic difference in common variant associations are unlikely to explain inter-ethnic differences in prevalence or presentation of T2D.

    Valid skinfold thickness (SFT) equations for the prediction of body fat are currently unavailable for South Asian women and would be a potentially robust field tool. Our aim was to assess the validity of existing SFT equations against deuterium ((2)H2O) dilution and, if invalid, to develop and validate an SFT equation for % fat mass (%FM) in Sri Lankan women. H2O dilution was used with Fourier transform infrared (FTIR) spectroscopy as the criterion method for the assessment of %FM in urban Sri Lankan women (30-45 years). This data was used to assess the validity of available SFT equations and to generate and validate a new SFT equation for the prediction of %FM against the criterion method. Women (n = 164) were divided into validation and cross-validation groups for the development and validation of the new equation. The level of agreement between the %FM calculated by the final derived prediction equation and the %FM obtained by (2)H2O dilution was assessed using Pearson's correlation coefficient (R) and Bland Altman plots. Student's t test was used to assess over- or underestimation, and significance was set at p < 0.05. Existing equations significantly (p < 0.001) underestimated %FM compared with the (2)H2O dilution method. The final equation obtained was %FM = 19.621 + (0.237*weight) + (0.259*triceps). When compared with (2)H2O dilution, %FM by the equation was not significantly different. There was a significant (p < 0.001) correlation between %FM by the reference method and %FM by the equation. The limit of agreement by Bland Altman plot was narrow with a small mean positive bias. Existing SFT equations were not applicable to this population. The new equation derived was valid. We report a new SFT equation to predict %FM in women of South Asian ancestry suitable for field use.

    Oral squamous cell carcinoma (OSCC) is one of the major health problems in Sri Lanka and the disease is associated with the habit of Betel Quid (BQ) chewing. Using 35k oligo microarrays, we analyzed the gene expression profile of 15 Sri Lankan patients diagnosed with OSCCs and pair-wised normal controls and correlated the findings with the clinicopathological data. Following the recording of the scanned array images and data analysis, results for selected candidate genes were verified using QRT-PCR. Upon analysis, a total of 263 genes [71 (27%) of unknown functions previously not reported in OSCCs and 192 (73%) of known functions] were found as differentially expressed between tumors and controls. For the genes with known functions, 66 (34%; such as COL4A1, MMP1, MMP3, PLAU, SPARC and KRT19) were previously reported in OSCC and for the remaining 126 (66%; such as CD47, APOL3, RRAGC, BPIL1 and AZGP1) this is the first report in OSCCs. Hierarchical clustering of the differentially expressed 263 genes grouped the samples into several clusters with the larger one being dominated by tumors of stage 3 and 4. Two cases (a verrucous SCC and an advanced SCC), did not cluster with any of the other samples. We found two main biological pathways (cell communication and integrin-mediated cell adhesion) and 5 gene ontology categories (transcription regulator activity, structural molecule activity, intracellular signaling, cytoskeleton and signal transduction) of relevance to the OSCCs examined. Results from the QRT-PCR verified the results from the microarray experiment. This study provides valuable information on gene expression profile of OSCCs of habitual users of BQ from Sri Lanka. Of particular interest were the list of genes of known and unknown functions and the two biological pathways that we suggest as candidate genes in oral cancers associated with BQ chewing in Southeast Asia, in particular Sri Lanka. The suggested candidate genes might be used as molecular biomarkers

    Developmental problems in children can be alleviated to a great extent with early detection and intervention through periodic screening for developmental delays during pre-school ages. Currently, there is no established system for developmental screening of children in Sri Lanka. Although some developmental norms, which are similar to those of Denver Developmental Screening Test-II (DDST-II), have been introduced into the Sri Lankan Child Health Developmental Record (CHDR), those norms have not been standardized to the Sri Lankan child population. The aim of this research was to establish Sri Lankan norms for DDST-II and to test the universal and regional applicability of developmental screening tests by comparing the Sri Lankan norms with the norms of DDST-II and DDST-Singapore norms, the geographically nearest standardization of DDST-II. The norms were also compared with the milestones already available in the CHDR. DDST-II was adapted and standardized on a sample of 4251 Sri Lankan children aged 0-80 months. Thirteen public health nursing sisters were trained to collect the data as part of their routine work. The 25th, 50th, 75th and 90th percentile ages of acquiring each developmental milestone were then calculated using logistic regression. The Denver Developmental Screening Test for Sri Lankan Children (DDST-SL) was created. Most of the established DDST-SL norms were different to the comparable norms in DDST-II, DDST-Singapore and the CHDR. In view of the results of the study, it is imperative that developmental screening tests are used in context and are adapted and standardized to the populations in question before utilization. © 2011 Blackwell Publishing Ltd.

    Reported case was a 63-year-old female with end-stage osteoarthritis (OA) (Sandhigata Vata) of the left knee joint accompanied by exostoses. Radiology (X-ray) report confirmed it as a Kellgren-Lawrence grade III or less with exostoses. At the beginning, the Knee Society Rating System scores of pain, movement and stability were poor, and function score was fair. Srilankan traditional and Ayurveda medicine treatment was given in three regimens for 70 days. After 70 days, external treatment of oleation and 2 capsules of Shallaki (Boswellia serrata Triana and Planch) and two tablets of Jeewya (comprised of Emblica officinalis Gaertn., Tinospora cordifolia [Willd.] Millers. and Terminalia chebula Retz.), twice daily were continued over 5 months. Visual analogue scale for pain, knee scores in the Knee Society online rating system and a Ayurveda clinical assessment criteria was used to evaluate the effects of treatments in weekly basis. After treatment for 70 days, the Knee Society Rating System scores of pain, movement and stability were also improved up to good level and function score was improved up to excellent level. During the follow-up period, joint symptoms and signs and the knee scores were unchanged. In conclusion, this OA patient's quality of life was improved by the combined treatment of Sri Lankan traditional medicine and Ayurveda.

    We apply the universal properties with Gaussian orthogonal ensemble (GOE) of random matrices namely spectral properties, distribution of eigenvalues, eigenvalue spacing predicted by random matrix theory (RMT) to compare cross-correlation matrix estimators from emerging market data. The daily stock prices of the Sri Lankan All share price index and Milanka price index from August 2004 to March 2005 were analyzed. Most eigenvalues in the spectrum of the cross-correlation matrix of stock price changes agree with the universal predictions of RMT. We find that the cross-correlation matrix satisfies the universal properties of the GOE of real symmetric random matrices. The eigen distribution follows the RMT predictions in the bulk but there are some deviations at the large eigenvalues. The nearest-neighbor spacing and the next nearest-neighbor spacing of the eigenvalues were examined and found that they follow the universality of GOE. RMT with deterministic correlations found that each eigenvalue from deterministic correlations is observed at values, which are repelled from the bulk distribution.

    In the present study, we investigated the characteristics and sequelae of erupted supernumerary teeth (ST) in a sample of Sri Lankan children. Data were recorded from patients' clinical records, radiographs, models, and extracted teeth. The sample consisted of 239 ST from 218 patients. The mean age of the sample was 9.08 ± 2.47 years. The male-to-female ratio was 2.8:1. The majority (42.66%) of patients with ST were in aged 8-10 years. Many (94.94%) of the ST were located in the premaxilla (incisor), followed by the canine (4.22%), premolar (0.42%), and molar (0.42%) regions. The most common shape of ST teeth was conical. Malocclusion (59.83%) was the major problem associated with ST, and the clinical impact was highest on the 8-10-year age group. A strong association was observed between patients' age and clinical impact to the dentition (χ(2) =42.09, P=.000). Because the majority of ST can lead to malocclusion, especially in mixed dentition, awareness, early detection, and timely clinical intervention of ST are recommended. © 2016 John Wiley & Sons Australia, Ltd.

    To access the anti-hyaluronidase activity of Sri Lankan low grown orthodox orange pekoe (OP) grade black tea with a view to develop an anti-aging skin formulation. Methods: Five concentrations (0.125, 0.250, 0.500, 1.000 and 2.000 mg/mL) of black tea brew (BTB) were made using a freeze dried sample of Sri Lankan low grown orthodox OP grade black tea which was prepared according to international organization for standardization specification. Epigallocatechin gallate (EGCG) was used as the reference agent (concentrations tested: 0.012, 0.025, 0.050, 0.100 and 0.200 mg/mL). Anti-hyaluronidase activity of BTB and EGCG in vitro were ascertained spectrometrically using hyaluronic acid (from rooster comb) and bovine testicular hyaluronidase. Results: The results revealed that BTB had moderate [IC50=(1.09±0.12) mg/mL] and dose dependent (r2=0.94) anti-hyaluronidase activity. EGCG also exhibited dose dependent (r2=0.93, P<0.05) anti-hyaluronidase activity which was superior [IC50=(0.09±0.00) mg/mL] to BTB. Conclusions: Sri Lankan low grown orthodox OP grade black tea has promising anti-hyaluronidase activity in vitro and has the potential to be used as an anti-aging cosmaceutical. In addition, it may prove useful as a beverage in the management of allergy, some joint diseases and envenomation.

    Full Text Available The endangered Sri Lankan Leopard Panthera pardus kotiya occupies the island’s highly fragmented central hills where data on its feeding ecology and habitat use is largely absent. This study’s objective was to investigate diet and resource selection of leopards here with a focus on the extent of potential interactions with humans in this heavily populated, largely unprotected landscape. Fecal sample analysis was undertaken to investigate diet and sign index counts and selectivity index analysis to determine habitat and landscape features important to fine scale leopard utilization. Results indicated that leopards in the central hills hunt a wide range of prey (at least 10 genera, including larger species where available (e.g., Sambar Rusa unicolor and smaller, more specialized prey (e.g., Porcupine Hystrix indica where necessary. No domestic species were recorded in scat analysis (N=35 despite the availability of dogs Canis familiaris, suggesting such predation may be atypical in Sri Lanka. Leopards use a range of landscapes within the region including established and regenerating forests, plantation lands (e.g., pine, eucalyptus, tea, and areas in close proximity to human settlement. At a fine scale, areas of dense undergrowth including tall grasslands were preferred to more open forest, as well as to Pine Pinus caribaea monocultures. Avoidance of humans may be influencing these patterns. This study has important implications as researchers and managers necessarily expand beyond focusing on protected areas toward integrated, landscape-level conservation strategies.

    This study was designed to develop an inventory to measure peer violence among early teens (13-15 years of age) in schools in Sri Lanka. Development of SLETVI was carried out in two phases. In phase I, development of an operational definition for peer violence, identification, and finalizing violent acts for inventory was done by a combination of qualitative methods: a comprehensive literature review, focus group discussions among 13-15-year-old adolescents, their teachers and parents, and consultative meetings with experts in the field. Inventory was then pretested. In phase II, elaboration of SLETVI was carried out by administering it to a sample of 1700 adolescents (13-15 years old). Exploratory factor analysis using principal component analysis was performed separately for experiences of victimization and perpetration. Test-retest reliability of SLETVI was assessed. SLETVI included 37 items in three factors: "less severe violence," "severe physical," and "severe relational" violence. Combined use of qualitative and quantitative methods enabled development of a culturally valid and reliable operational inventory to assess early teenagers' peer violence in Sri Lankan and other South Asian schools.

  8. Agricultural adaptation to water scarcity in the Sri Lankan dry zone: A comparison of two water managment regimes

    2014-12-01

    The island nation of Sri Lanka is divided into two agro-climatic zones: the southwestern wet zone and the northeastern dry zone. The dry zone is exposed to drought-like conditions for several months each year. Due to the sporadic nature of rainfall, dry zone livelihoods depend on the successful storage, capture, and distribution of water. Traditionally, water has been captured in rain-fed tanks and distributed through a system of dug canals. Recently, the Sri Lankan government has diverted the waters of the nation's largest river through a system of centrally managed reservoirs and canals and resettled farmers to cultivate this newly irrigated land. This study uses remotely sensed MODIS and LANDSAT imagery to compare vegetation health and cropping patterns in these distinct water management regimes under different conditions of water scarcity. Of particular interest are the socioeconomic, infrastructural, and institutional factors that affect cropping patterns, including field position, water storage capacity, and control of water resources. Results suggest that under known conditions of water scarcity, farmers cultivate other field crops in lieu of paddy. Cultivation changes depend to a large extent on the institutional distance between water users and water managers as well as the fragmentation of water resources within the system.

    Hypertension is a major contributor to the global non-communicable disease burden. Family history is an important non-modifiable risk factor for hypertension. The present study aims to describe the influence of family history (FH) on hypertension prevalence and associated metabolic risk factors in a large cohort of South Asian adults, from a nationally representative sample from Sri Lanka. A cross-sectional survey among 5,000 Sri Lankan adults, evaluating FH at the levels of parents, grandparents, siblings and children. A binary logistic regression analysis was performed in all patients with 'presence of hypertension' as dichotomous dependent variable and using family history in parents, grandparents, siblings and children as binary independent variables. The adjusted odds ratio controlling for confounders (age, gender, body mass index, diabetes, hyperlipidemia and physical activity) are presented below. In all adults the prevalence of hypertension was significantly higher in patients with a FH (29.3%, n = 572/1951) than those without (24.4%, n = 616/2530) (p hypertension (OR:1.29; 95% CI:1.13-1.47), obesity (OR:1.36; 95% CI: 1.27-1.45), central obesity (OR:1.30; 95% CI 1.22-1.40) and metabolic syndrome (OR:1.19; 95% CI: 1.08-1.30). In all adults presence of family history in parents (OR:1.28; 95% CI: 1.12-1.48), grandparents (OR:1.34; 95% CI: 1.20-1.50) and siblings (OR:1.27; 95% CI: 1.21-1.33) all were associated with significantly increased risk of developing hypertension. Our results show that the prevalence of hypertension was significantly higher in those with a FH of hypertension. FH of hypertension was also associated with the prevalence of obesity, central obesity and metabolic syndrome. Individuals with a FH of hypertension form an easily identifiable group who may benefit from targeted interventions.

  12. The Securitisation of Sri Lankan Tourism in the Absence of Peace

    Full Text Available The military conflict in Sri Lanka may be over officially, but conflict continues as a ‘war without sound’ (community informant, Mullaitivu 2013, or as war by other means (Dahlman 2011. In the absence of peace and reconciliation, but the presence of economic growth, development by stealth proceeds. Much has been written about the militarisation of civilian life in Sri Lanka (Kadirgamar 2013; David 2013, but this paper focuses specifically on how militarisation has proceeded with little public protest or pushback. The political work accomplished by ‘securitisation’ is used to gain consent and create new space and capacity for state security measures and militarisation. This paper recasts the connections between security, peace, and development in post-war Sri Lanka, drawing on fieldwork in one area that connects all of these projects: tourism. An analysis of ‘war tourism’ in Sri Lanka shows how it reproduces threats to Sri Lanka’s security at the same time that it celebrates military victory and might. Tourism encapsulates economic, security, and development agendas in very specific ways. Tourist sites mobilise fear of potential terrorism and return to the rule of the Liberation Tigers of Tamil Eelam (LTTE, if vigilance and militarisation are not maintained. In such a context of risk, development is best done by the military. Within this logic of securitisation, militarisation becomes a common sense approach. How is this common sense produced? The securitisation of development is vivid in the post-war context of Sri Lanka, inextricably tied to neoliberal imperatives to convey a democratic, stable country that is open to and good for business.

Methods: S-ACT-l, a white amorphous powder was separated from more polar fractions of the hexane soluble of 1:1 CH2Cl2/MeOH extract and subjected to 1H, 1 3C NMR and IR Spectroscopy after reverse phase HPLC for identification. Effects of S-ACT-1 on human sperm motility was assessed in vitro at 10,100 and 1000μg/Ml concentrations at 37℃ for 0, 5, 15, 30 and 60 min. Results: S-ACT-1 was identified as a glycolipid sulfate. The lower dose increased the sperm motility slightly, whilst the medium dose significantly increased the motility ( P < 0.05) from 5 min of incubation reaching a peak at 15 min and the stimulant effect was sustained throughout the experimental period. Furthermore, the medium dose rendered 80% of the immotile viable sperm motile.In contrast, the highest dose impaired the sperm motility. The sperm stimulating activity of S-ACT-1 was dose-depen dent and had a bell-shaped dose response curve for all the 5 incubation periods. Conclusion: S-ACT-1 of Gelidiella acerosa is a Sulfono glycolipid. S-ACT-1 has a potent sperm motility stimulating activity in vitro and has the potential to be developed into a sperm stimulant.

    The cranial arterial pattern of artiodactyls deviates significantly from the typical mammalian pattern. One of the most striking atypical features is the rete mirabile epidurale: a subdural arterial meshwork that functionally and anatomically replaces the arteria carotis interna. This meshwork facilitates an exceptional ability to cool the brain, and was thought to be present in all artiodactyls. Recent research, however, has found that species of mouse deer (Artiodactyla: Tragulidae) endemic to the Malay Archipelago possess a complete a. carotis interna instead of a rete mirabile epidurale. As tragulids are the sister group to pecoran ruminants, the lack of a rete mirabile epidurale in these species raises intriguing evolutionary questions about the origin and nature of artiodactyl thermoregulatory cranial vasculature. In this study, cranial arterial patterns are documented for the remaining species within the Tragulidae. Radiopaque latex vascular injection, computed tomography (CT-scanning), and digital 3-dimensional anatomical reconstruction are used to image the cranial arteries of a Sri Lankan spotted chevrotain, Moschiola meminna. Sites of hard and soft tissue interaction were identified, and these osteological correlates were then sought in nine skulls representative of the remaining tragulid species. Both hard and soft tissue surveys confirm that the presence of an a. carotis interna is the common condition for tragulids. Moreover, the use of a 3-D, radiographic anatomical imaging technique enabled identification of a carotico-maxillary anastomosis that may have implications for the evolution of the artiodactyl rete mirabile epidurale.

    Full Text Available The present study was conducted to determine the number of roots and morphology of the root canal system of permanent mandibular first molars (M1 in a Sri Lankan population. Sample of 529 M1 teeth was used. The number of roots was examined and the lengths of the mesial and distal roots were measured to the nearest 0.01 mm. Vacuum injection protocol was used to inject China ink into the root canal system, making it transparent. Root canal morphology was recorded using Vertucci’s classification. Presence of furcation canals, position of lateral canals, intercanal communications, level of bifurcation, and convergence of the root canal system were recorded. M1 showed three roots in 4.1% of the sample. Commonest root canal morphology of the mesial root was type IV and the distal root was type I. The level of bifurcation of the root canals was commonly observed in the cervical one-third of the root while convergence was observed in the apical one-third in both roots. Prevalence of three rooted mandibular first molars is less than 5%. Mesial root showed the most variable canal morphology. Prevalence of furcation canals was 1.5% while that of middle mesial canals was 0.2%.

    The epidemiologic status of melioidosis in Sri Lanka was unclear from the few previous case reports. We established laboratory support for a case definition and started a nationwide case-finding study. Suspected Burkholderia pseudomallei isolates were collated, identified by polymerase chain reaction assay, referred for Matrix Assisted Laser Desorption Ionization-Time of Flight analysis and multilocus sequence typing (MLST), and named according to the international MLST database. Between 2006 and early 2014, there were 32 patients with culture-confirmed melioidosis with an increasing annual total and a falling fatality rate. Patients were predominantly from rural communities, diabetic, and male. The major clinical presentations were sepsis, pneumonia, soft tissue and joint infections, and other focal infection. Burkholderia pseudomallei isolates came from all parts of Sri Lanka except the Sabaragamuwa Province, the south central hill country, and parts of northern Sri Lanka. Bacterial isolates belonged to 18 multilocus sequence types, one of which (ST 1137) was associated with septicemia and a single-organ focus (Fisher's exact, P = 0.004). Melioidosis is an established endemic infection throughout Sri Lanka, and is caused by multiple genotypes of B. pseudomallei, which form a distinct geographic group based upon related sequence types (BURST) cluster at the junction of the southeast Asian and Australasian clades.

    Full Text Available Abstract Background On the 26th December 2004 the Asian tsunami devastated the Sri Lankan coastline. More than two years later, over 14,500 families were still living in transitional shelters. This study compares the health of the internally displaced people (IDP, living in transitional camps with those in permanent housing projects provided by government and non-government organisations in Sri Lanka. Methods This study was conducted in seven transitional camps and five permanent housing projects in the south west of Sri Lanka. Using an interviewer-led questionnaire, data on the IDPs' self-reported health and housing conditions were collected from 154 participants from transitional camps and 147 participants from permanent housing projects. Simple tabulation with non-parametric tests and logistic regression were used to identify and analyse relationships between housing conditions and the reported prevalence of specific symptoms. Results Analysis showed that living conditions were significantly worse in transitional camps than in permanent housing projects for all factors investigated, except 'having a leaking roof'. Transitional camp participants scored significantly lower on self-perceived overall health scores than those living in housing projects. After controlling for gender, age and marital status, living in a transitional camp compared to a housing project was found to be a significant risk factor for the following symptoms; coughs OR: 3.53 (CI: 2.11–5.89, stomach ache 4.82 (2.19–10.82, headache 5.20 (3.09–8.76, general aches and pains 6.44 (3.67–11.33 and feeling generally unwell 2.28 (2.51–7.29. Within transitional camp data, the only condition shown to be a significant risk factor for any symptom was household population density, which increased the risk of stomach aches 1.40 (1.09–1.79 and headaches 1.33 (1.01–1.77. Conclusion Internally displaced people living in transitional camps are a vulnerable population and

    The month of May 2015 marked the sixth year since the end of conflict in Sri Lanka. The cause of death, destruction and displacement, three decades of conflict has had a major impact on health, especially on mental health of those affected by forced displacement. Post-conflict regions of Sri Lanka has seen improvements in many areas, including resettlement of displaced populations and rebuilding of health-related infrastructure. However, substantial gaps exist around the management of health needs among returnee populations, especially in the area of psychosocial health. Long-term mental health and resilience trajectories of those affected by prolonged displacement and experiencing return migration during post-conflict periods remain important, yet critically understudied areas.

    Methods of torture vary from country to country and sometimes within regions in the same country. Knowing torture methods used in a country or region assists in evaluating injuries, scars and other chronic sequelae of torture. Medical records of 100 victims of torture examined between 1998 and 2001 in the Judicial Medical Officer's Office in Colombo, Sri Lanka, were perused to gather data on torture methods used in Sri Lanka during that period. Altogether 68 methods of torture had been used on these victims. They included assault with blunt and sharp weapons, burns with lighted cigarettes, 'dry submarino', kicking, 'wet submarino', 'hanging', electric torture, 'falaka' and many more. However, only 18% of victims had any physical residual effects, highlighting the typical objective of torture, which is inflicting maximum pain without causing serious injury or death.

  4. Sri Lankan livelihoods after the tsunami: searching for entrepreneurs, unveiling relations of power.

    2015-01-01

    This paper analyses the performance of aid-funded livelihoods recovery efforts in Sri Lanka following the Indian Ocean tsunami of 26 December 2004, with special attention paid to the effects on the rural poor. It argues that successful livelihoods recovery was hampered by an excessive focus by aid agencies on entrepreneurs and entrepreneurship, and by the lack of a politically informed understanding of the economy. Based on ethnographic and survey-based research, the study demonstrates that the category of 'entrepreneur' is misleading for large parts of the economy. Indeed, the desire to build an entrepreneurial economy actually hampered successful livelihoods recovery in Sri Lanka and, in some cases, reinforced inequitable relations of power. The paper concludes that for livelihoods recovery programmes to be effective, they must be founded on an understanding of the relations of power that constitute the economy; these relations operate across scales, and are historically and geographically specific.

    Sea snakes are among the most venomous creatures encountered around coasts and reefs, in estuaries, rivers and at sea. Their venoms are more toxic than those of land snakes. However, they are rarely aggressive or menacing. Bites have become unusual with the advent of modern fishing methods but the two encounters we report, in the Indian Ocean off the shores of Sri Lanka, emphasise that sea snake bites may not result in envenoming.

    Full Text Available Chronic kidney disease (CKD is a growing problem in Sri Lanka. Diabetes and hypertension are the main contributors to the disease burden. A new form of CKD of uncertain etiology (CKD-u is the predominant form of CKD in certain parts of Sri Lanka, threatening to reach epidemic proportions. A cross-sectional descriptive study was carried out over a three-month period at the National Hospital of Sri Lanka to identify the underlying etiologic factors for the disease in a cohort of patients with CKD. A total of 200 patients were studied with a mean age of 50.57 years. Of them, 108 (54% were in CKD stage V. Majority of the patients were from the western province (137, 68.5% with only five (2.5% from provinces with high prevalence of CKD-u. The most common underlying causes of CKD were diabetes (88, 44% and hypertension (34, 17%. However, in patients younger than 40 years of age the most common cause was glomerulonephritis (20, 42.6%. Diabetes was the most common cause of CKD among patients from the western province (74, 54%. The prevalence of CKD-u was twice as high in patients from areas outside the western province compared with patients from this province (P > 0.05. The low prevalence of CKD-u in the study population could be the result of poor representation of patients from provinces with high prevalence of CKD-u.

    Gender norms have been challenged by unmarried rural women's migration for employment to urban Sri Lankan Free Trade Zones (FTZ). Men are described as looking for sexual experiences among the women workers, who are then accused of engaging in premarital sex, something seen as taboo in this context. Increased sexual and reproductive health and rights (SRHR) risks for women workers are reported. To improve SRHR it is important to understand the existing gender ideals that shape these behaviours. This qualitative study explores men's perspectives on gender relations in an urban Sri Lankan FTZ, with a focus on heterosexual relationships and premarital sex. Further, possible implications for SRHR of women workers in FTZs are discussed. Eighteen qualitative semi-structured interviews were conducted with men living or working in an urban Sri Lankan FTZ and were analysed using thematic analysis. Two conflicting constructions of masculinity; the 'disrespectful womaniser' and the 'respectful partner', were discerned. The 'disrespectful womaniser' was perceived to be predominant and was considered immoral while the 'respectful partner' was considered to be less prevalent, but was seen as morally upright. The migrant women workers' moral values upon arrival to the FTZ were perceived to deteriorate with time spent in the FTZ. Heterosexual relationships and premarital sex were seen as common, however, ideals of female respectability and secrecy around premarital sex were perceived to jeopardize contraceptive use and thus counteract SRHR. The 'disrespectful' masculinity revealed in the FTZ is reflective of the patriarchal Sri Lankan society that enables men's entitlement and sexual domination over women. Deterioration of men's economic power and increase of women's economic and social independence may also be important aspects contributing to men's antagonistic attitudes towards women. The promotion of negative attitudes towards women is normalized through masculine peer pressure

    The 2004 Indian Ocean tsunami resulted in a tragic loss of life and immense suffering. This article explores the ways in which a group of people from Sri Lanka worked to address the disruption to their life narratives caused by the loss of loved ones. We go beyond a focus on 'talk' in narrative research in health psychology to explore the importance of material objects in sustaining continued bonds with the deceased. This article provides an alternative to the tendency in mainstream psychology to pathologise grief and highlights the importance of culturally patterned responses to disaster. © The Author(s) 2013.

    Cassava ranks fifth among the starch producing crops of the world, its annual bioethanol yield is higher than for any other crop. Cassava cultivar KU50, the most widely grown cultivar for non-food purposes is susceptible to Sri Lankan cassava mosaic virus (SLCMV). The objective of this work was to engineer resistance to SLCMV by RNA interference (RNAi) in order to increase biomass yield, an important aspect for bioethanol production. Here, we produced transgenic KU50 lines expressing dsRNA homologous to the region between the AV2 and AV1 of DNA A of SLCMV. High level expression of dsRNA of SLCMV did not induce any growth abnormality in the transgenic plants. Transgenic lines displayed high levels of resistance to SLCMV compared to the wild-type plants and no virus load could be detected in uninoculated new leaves of the infected resistant lines after PCR amplification and RT-PCR analysis. The agronomic performance of the transgenic lines was unimpaired after inoculation with the virus as the plants presented similar growth when compared to the mock inoculated control plants and revealed no apparent reduction in the amount and weight of tubers produced. We show that the resistance is correlated with post-transcriptional gene silencing because of the production of transgene specific siRNA. The results demonstrate that transgenic lines exhibited high levels of resistance to SLCMV. This resistance coupled with the desirable yield components in the transgenic lines makes them better candidates for exploitation in the production of biomass as well as bioethanol.

    The reproductive and sexual health of adolescents is an important health concern and a focus of global attention. In Sri Lanka, a lack of understanding about adolescent reproductive and sexual health needs is a matter of national concern. A survey was undertaken to examine the sexual knowledge, attitudes and behaviours of school going adolescents in Sri Lanka. A random sample of schools was selected from one district. Data were collected by a self-completion questionnaire and analysed using SPSS. Response rate was 90%. 2020 pupils (26% boys, 74% girls) aged 16-19 years (mean=16.9) participated, the majority Sinhalese (97%). Most reported a good parent-child relationship (88%). A minority (34%) discussed sexual issues with parents. Health professionals were the preferred source of sexual information (32%) rather than parents (12.5%) or friends (5.6%). Less than 1% demonstrated satisfactory sexual and reproductive knowledge levels. 1.7% were sexually active (30 boys vs 5 girls), the majority with same age partners. 57% used contraception at first intercourse. There is an imperative to address the lack of sexual and reproductive knowledge. A minority of school going adolescents become sexually active. These individuals are potentially vulnerable and services need to be developed to meet their needs.

    Different hospitals produce different cultures-products of relationships between people of different staff categories and people from external community groups. These relationships demonstrate unique social dynamics in rural peripheral hospitals that form a major part of the health care system in Sri Lanka and other developing countries. Understanding the existing social dynamics might be useful when trying to implement new treatment guidelines that can involve behavior change. We aimed to explore the existing social dynamics in peripheral hospitals in rural Sri Lanka by examining the treatment related to cases of acute self-poisoning that is a common, highly interactive medical emergency. These hospitals demonstrate higher levels of community influence in treatment decisions and closer interactions between hospital staff. We argue that health care teamwork is effective in peripheral hospitals, resulting in benefits to all staff, who see these hospitals as better places to work and train, in contrast to a commonly held belief that such rural hospitals are disadvantaged and difficult places.

    2014-12-01

    Full Text Available This paper examines the effects of the modernization on the living arrangements of elderly people in six selected communities representing urban, semi-urban, estate, rural, colonized settlement and fishing villages in Sri Lanka. The paper concludes that the modernization of the economy and society has exacerbated an intergenerational rift leading to an intensification of tensions between elderly people and other family members, despite the fact that the percentage of older people living with their children remains high. Such coresidence or intergenerational living comprises many types of living arrangements, and leads to mixed results for care of the elderly. Many elderly people have developed mechanisms to counteract the negative effects of coresidence: seeking independence during old age, by earning their own income and living alone or living with the spouse, indulging in behaviors such as drinking, spending time outside the home with friends of similar age, or creating their own living space within coresidence.

    This study aimed to determine whether psychological factors associated with Post-Traumatic Stress Disorder (PTSD) identified in Western samples generalize to low Social-Economical-Status (SES) populations in an underdeveloped Asian country. The study included 113 survivors of the 2004-tsunami on the south coast of Sri Lanka, recruited from 4 preschools and 10 villages for displaced persons. With logistic regressions the relations between interview-based PTSD diagnosis and psychological factors were assessed, controlling for putative confounders. Fifteen months post-trauma the prevalence of PTSD was 52.2%. Multivariate analyses indicated that negative interpretation of tsunami-memories was significantly (PPTSD. Of the putative confounders, gender and (non-replaced) lost work equipment were related to current PTSD (PPTSD is quite universal, suggesting that interventions focusing on this factor may be important in treatment of tsunami survivors who are suffering from chronic PTSD.

    Full Text Available We report three symptomatic children with profound biotinidase deficiency from Sri Lanka. All three children presented with typical clinical features of the disorder. The first is homozygous for a missense mutation in the BTD gene (c.98_104 del7insTCC; p.Cys33PhefsX36 that is commonly seen in the western countries, the second is homozygous for a novel missense mutation (p.Ala439Asp, and the third is the first reported instance of a contiguous gene deletion causing the enzyme deficiency. In addition, this latter finding exemplifies the importance of considering a deletion within the BTD gene for reconciling enzymatic activity with genotype, which can occur in asymptomatic children who are identified by newborn screening.

    The glycaemic index (GI) concept ranks individual foods and mixed meals according to the blood glucose response. Low-GI foods with a slow and prolonged glycaemic response are beneficial for diabetic people, and several advantages have been suggested also for non-diabetic individuals. The recent investigations imply an increasing prevalence of diabetes mellitus in Sri Lanka. Thus, the present study was designed primarily to determine the glycaemic indices of some bread varieties in Sri Lanka as bread has become a staple diet among most of the urban people. A second objective was to observe the effects of macronutrients and physicochemical properties of starch on GI. Glycaemic responses were estimated according to FAO/WHO guidelines and both glucose and white bread were used as standards. Non-diabetic individuals aged 22-30 years (n=10) participated in the study. The test meals included white sliced bread, wholemeal bread, ordinary white bread and a mixed meal of wholemeal bread with lentil curry. The GI values (+/-standard error of the mean) of the meals were 77+/-6, 77+/-6, 80+/-4, 61+/-6, respectively (with glucose as the standard). The GI values of the bread varieties or the meal did not differ significantly (P >0.05). However, the meal can be categorized as a medium-GI food while the other bread varieties belong to the high-GI food group. A significant negative correlation was obtained with protein (P=0.042) and fat (P=0.039) contents of the food items and GI. Although the GI values of the foods are not significantly different, the inclusion of lentils caused the GI to decrease from a high-GI category to a medium-GI category. According to the present study, a ratio of 1.36 can be used to interconvert the GI values obtained with the two standards.

    Full Text Available Background: Faculty of Medicine, University of Kelaniya, Sri Lanka conducts a one month under graduate training programme during their fourth year at the University family practice centre. Students get training in history taking, clinical examination, patient management and practice management during this attachment. This study was conducted to look at the patients′ attitude towards student participation during consultation. Materials and Methods: This was a descriptive cross sectional study. All the patients who were 16 years and above during a 2 month period were included in the study. Structured questionnaire was administered by demonstrators following a consultation where students were present. Their demographic data, number of consultations with student participation and questions related to presence of students at various stages of the consultation were asked. Results: Total of 85 patients took part in the study and 81.3% of them were females. 88.8% were of the opinion that they benefited by the interaction with medical students while 93.8% thought students understood their problems. 26.3% patients preferred a medical student of the same sex during consultation while 71.3 had not expressed any opinion in this regard. Only 3.8% and 5% wanted the doctor alone during history taking and examination respectively. Almost every patient was happy that they could help the undergraduate training. Discussion: As expected results of the study showed that patients were willing to take part in undergraduate training without any reservation. These results are compatible with the previous studies done in the western world and data is not available form either Sri Lanka or other Asian countries.

    Flavonol glycosides in tea leaves have been quantified as aglycones, quercetin, myricetin, and kaempferol. Occurrence of the said compounds was reported in fruits and vegetable for a long time in association with the antioxidant potential. However, data on flavonols in tea were scanty and, hence, this study aims to envisage the flavonol content in a representative pool of accessions present in the Sri Lankan tea germplasm. Significant amounts of myricetin, quercetin, and kaempferol have been detected in the beverage type tea accessions of the Sri Lankan tea germplasm. This study also revealed that tea is a good source of flavonol glycosides. The Camellia sinensis var. sinensis showed higher content of myricetin, quercetin, and total flavonols than var. assamica and ssp. lasiocalyx. Therefore flavonols and their glycosides can potentially be used in chemotaxonomic studies of tea germplasm. The nonbeverage type cultivars, especially Camellia rosaflora and Camellia japonica Red along with the exotic accessions resembling China type, could be useful in future germplasm studies because they are rich sources of flavonols, namely, quercetin and kaempferol, which are potent antioxidants. The flavonol profiles can be effectively used in choosing parents in tea breeding programmes to generate progenies with a wide range of flavonol glycosides. PMID:27366737

    Full Text Available Objective: To investigate the antifungal potential of different grades of Sri Lankan orthodox black tea [orange pekoe, broken orange pekoe fannings (BOPF and Dust No. 1] belonging to the three agro-climatic elevations (low, mid and high. Methods: Antifungal activity was assessed in vitro using methanolic extracts (300 µg/disc and agar disc diffusion bioassay technique against three Candida species, Candida albicans (C. albicans, Candida glabrata (C. glabrata, and Candida tropicalis. ketoconazole and itraconazole mixture was used as positive control (10 µg/disc and methanol was used as the negative control. The minimum inhibitory concentrations were also determined using standard protocols. Results: None of the extracts were effective against Candida tropicalis. Furthermore, orange pekoe grade tea belonging to all agro-climatic elevations did not induce any antifungal activity against C. albicans and C. glabrata as well. Conversely, Dust No. 1 belonging to all three agro-climatic elevations and low-grown BOPF showed moderate antifungal activity against C. albicans and C. glabrata. Interestingly, the severity of the antifungal effect varied with agroclimatic elevations. The minimum inhibitory concentrations ranged from 64.00–128.00 µg/mL against C. glabrata and 128.00-256.00 µg/mL against C. albicans. Conclusions: Sri Lankan Dust No. 1 and BOPF have marked antifungal activity in vitro and offer promise to be used as a supplementary beverage in prophylaxis and during drug treatment in candidiasis.

    Full Text Available AbstractProtecting the right of the local community/country to use their own genetic resourcesavailable in a particular area is an important element of environmental and biodiversityconservation. However, one of the biggest biodiversity conservation challenges faced bysouthern peripheral countries is biopiracy and related issues. Community based ecotourism(CBET is a well-established concept and its implementation is an important component in manyregional development strategies. This research argues that though CBET which originated as awestern concept has been successfully applied in number of projects, it generates biopiracychallenges in its implementation when CBET operates within different geo-political, economicand cultural contexts. This research examines such challenges to CBET initiatives in theSinharaja world heritage site, Sri Lanka. A qualitative-inductive research methodology hasprincipally guided this research to examine the socio-cultural and socio-economic context ofbiopiracy issues. A total of 293 participants have informed this research including 193interviews. A critical discourse analysis (CDA method is used to examine both primaryqualitative data collected through participant and direct observation, interviews and secondarydata. One of the main findings is that despite plans being developed at a community level, inwider context, challenges of biopiracy related to superimposed capitalism contest CBETideologies. Superimposed capitalism results in individualistic and competitive behaviours thatundermine collaborative and responsible community approach. Presently, smuggling out ofWallapatta plant (Gyrinops walla and gathering of Spotted bowfinger gecko (Cyrtodactylustriedra which is an endemic nocturnal reptile species have become profitable in KudawaSinharajasite and a growing number of biopirates venture into here.

    Full Text Available Sri Lanka has variety of herbs whose effectiveness has been proven across many generations. These herbs are classified into two groups — ‘heating’ and ‘cooling’, based on the physiological reactions upon consumption. Application-wise, the ‘cooling’ herbs are administered to patients contracted with diabetes, imbalances in the lipid profile, or even cancer. However, this classification has been misunderstood due to inconsistent interpretations and lack of scientific reasoning. This study systematically determines the rationale behind this classification, by specifically evaluating the antioxidant activity of 18 herbs — nine herbs from each category. The oxygen radical absorbance capacities, DPPH radical scavenging activities, and the total phenolic contents are analyzed here. The ‘heating’ herbs have a comparatively lower antioxidant potential than the ‘cooling’ herbs. The total phenolic contents correlate with the antioxidant values. It can be hypothesized that the high antioxidant potential of the ‘cooling’ herbs may have been responsible for the containment of the diseases mentioned previously.

    The current study evaluates the migration of benzene, toluene, ethylbenzene, xylene (BTEX) and phthalates into artificial saliva from natural rubber latex (NRL) balloons available for sale in Sri Lanka. It was discovered that at least one BTEX compound migrated from almost all the brands. The migration of four phthalates; diethyl phthalate, dibutyl phthalate, di-isobutyl phthalate and butyl benzyl phthalate were also observed. Migratory levels of BTEX and phthalates in most of the balloon brands were above the permissible levels set by the European Union. Assessment of factors affecting the migratory levels indicated migration under active mouthing conditions and migration from the neck region of the balloons were significantly higher. The migratory levels were observed to decrease with storage time, and in certain brands the BTEX levels decreased below the permissible level. One-way ANOVA indicated no significant differences (p ≥ 0.05) in migratory levels of each individual compound within the same brand for both BTEX and phthalates. When compared among different brands, BTEX levels indicated significant differences (p ≤ 0.05), while phthalate levels were observed to not be significantly different (p ≥ 0.05). A significant difference was also observed (p ≤ 0.05) among the migratory levels of compounds under each test condition evaluated as factors affecting the migratory level. Furthermore, the solvent based colorants added to color the latex were found to be the source of BTEX and phthalates in the NRL balloons.

    Setaria digitata is an animal filarial parasite with natural hosts of cattle and buffaloes that causes mild disease conditions. Infection of non-permissive hosts such as goats, sheep and horses, by this nematode can cause cerebrospinal nematodiasis that leads to lumbar paralysis and the eventual death of the animals and inflicts considerable economic losses on livestock farmers. Wolbachia are obligate mutualistic endosymbionts for some filarial nematodes and are currently being targeted for the control of diseases caused by these parasites. However, little is known about the occurrence of this endosymbiont in the Setariidae family. In this work, worms collected from infected cattle in Sri Lanka were morphologically identified as S. digitata and tested for the presence of Wolbachia by PCR screening using the WSP- and Wolbachia-specific 16S rRNA and multilocus sequence typing primers that were designed to amplify the gatB, coxA, hcpA, ftsZ and fbpA sequences of Wolbachia. The presence of endobacteria in S. digitata was also examined by whole-mount immunofluorescence staining of the parasites and transmission electron microscopic studies. These analyses did not produce evidence of presence of Wolbachia or any other endosymbiotic bacteria in S. digitata, whereas such evidence was found in Brugia malayi, which was used as a positive control in this study.

    Previous research has shown that higher Emotional Intelligence (EI) is associated with better academic and work performance. The present study intended to explore the relationship between EI, perceived stress and academic performance and associated factors among medical undergraduates. This descriptive cross-sectional research study was conducted among 471 medical undergraduates of 2nd, 4th and final years of University of Colombo, Sri Lanka. Students were rated on self administered Perceived Stress Scale (PSS) and Schutte Self-Report Emotional Intelligence Test (SEIT). Examination results were used as the dichotomous outcome variable in a logistic regression analysis. Females had higher mean EI scores (p = 0.014). A positive correlation was found between the EI score and the number of extracurricular activities (r = 0.121, p = 0.008). Those who were satisfied regarding their choice to study medicine, and who were planning to do postgraduate studies had significantly higher EI scores and lower PSS scores (p <0.001). Among final year undergraduates, those who passed the Clinical Sciences examination in the first attempt had a higher EI score (p <0.001) and a lower PSS score (p <0.05). Results of the binary logistic-regression analysis in the entire study population indicated that female gender (OR:1.98) and being satisfied regarding their choice of the medical undergraduate programme (OR:3.69) were significantly associated with passing the examinations. However, PSS Score and engagement in extracurricular activities were not associated with 'Examination Results'. Higher EI was associated with better academic performance amongst final year medical students. In addition a higher EI was observed in those who had a higher level of self satisfaction. Self-perceived stress was lower in those with a higher EI. Enhancing EI might help to improve academic performance among final year medical student and also help to reduce the stress levels and cultivate

    Migrant worker abuse is well recognised, but poorly characterised within the scientific literature. This study aimed to explore patterns of abuse amongst Sri Lankan women returning home after working as domestic maids. Sri Lanka has over 2 million of its citizens employed overseas as international labor migrants. A cross-sectional study was conducted on Sri Lankan female domestic maids returning from the Middle East region who were referred for medico-legal opinion. A total of 20 women were included in the study. Average length of their employment overseas was 14 months. Complaints of physical violence directed mainly through their employers were made by 60% of women. Upon physical examination, two-thirds had evidence of injuries, with a third being subjected to repetitive/systematic violence. Eighty percent suffered some form of psychological trauma. Personal identity papers and travel documents had been confiscated by the employer in 85% of cases, with two thirds indicating they were prevented and/or restricted from leaving their place of work/residence. Our study demonstrates that female domestic maid abuse manifests through multiple pathways. Violence against such workers span the full spectrum of physical, financial, verbal, emotional abuse and neglect, as defined by the World Health Organization. Findings from this exploratory study cannot be generalized to the large volume of migrant worker outflows. Further research is needed to determine incidence and define patterns in other migrant worker categories such as low-skilled male workers.

    This study focused on determining the past changes and predicting the future trends in eutrophication of the Bolgoda North lake, Sri Lanka using in situ Chlorophyll-a (Chl-a) measurements and Advanced Spaceborne Thermal Emission and Reflectance Radiometer (ASTER) satellite data. This Lake is located in a mixed land use area with industries, some agricultural lands, middle income and high income housing, tourist hotels and low income housing. From March to October 2013, water samples from five sampling sites were collected once a month parallel to ASTER overpass and Chl-a, nitrate and phosphate contents of each sample were measured using standard laboratory methods. Cloud-free ASTER scenes over the lake during the 2000-2013 periods were acquired for Chl-a estimation and trend analysis. All ASTER images were atmospherically corrected using FLAASH software and in-situ Chl-a data were regressed with atmospherically corrected three ASTER VNIR band ratios of the same date. The regression equation of the band ratio and Chl-a content with the highest correlation, which was the green/red band ratio was used to develop algorithm for generation of 15-m resolution Chl-a distribution maps. According to the ASTER based Chl-a distribution maps it was evident that eutrophication of this lake has gradually increased from 2008-2011. Results also indicated that there had been significantly high eutrophic conditions throughout the year 2013 in several regions, especially in water stagnant areas and adjacent to freshwater outlets. Field observations showed that this lake is receiving various discharges from factories. Unplanned urbanization and inadequacy of proper facilities in the nearby industries for waste management have resulted in the eutrophication of the water body. If the present trends of waste disposal and unplanned urbanization continue, enormous environmental problems would be resulted in future. Results of the present study showed that information from satellite remote

    Full Text Available Cassava mosaic disease is a major constraint to cassava cultivation worldwide. In India, the disease is caused by Indian cassava mosaic virus (ICMV and Sri Lankan cassava mosaic virus (SLCMV. The Agrobacterium Ti plasmid virulence gene virE2, encoding a nuclear-localized, single-stranded DNA binding protein, was introduced into Nicotiana benthamiana to develop tolerance against SLCMV. Leaf discs of transgenic N. benthamiana plants, harboring the virE2 gene, complemented a virE2 mutation in A. tumefaciens and produced tumours. Three tested virE2 transgenic plants displayed reduction in disease symptoms upon agroinoculation with SLCMV DNA A and DNA B partial dimers. A pronounced reduction in viral DNA accumulation was observed in all three virE2 transgenic plants. Thus, virE2 is an effective candidate gene to develop tolerance against the cassava mosaic disease and possibly other DNA virus diseases.

    Rising human demand and climatic variability have created greater uncertainty regarding global food trade and its effects on the food security of nations. To reduce reliance on imported food, many countries have focused on increasing their domestic food production in recent years. With clear goals for the complete self-sufficiency of rice production, Sri Lanka provides an ideal case study for examining the projected growth in domestic rice supply, how this compares to future national demand, and what the associated impacts from water and fertilizer demands may be. Using national rice statistics and estimates of intensification, this study finds that improvements in rice production can feed 25.3 million Sri Lankans (compared to a projected population of 23.8 million people) by 2050. However, to achieve this growth, consumptive water use and nitrogen fertilizer application may need to increase by as much as 69 and 23 %, respectively. This assessment demonstrates that targets for maintaining self-sufficiency should better incorporate avenues for improving resource use efficiency.

  17. Effect of a brief outreach educational intervention on the translation of acute poisoning treatment guidelines to practice in rural Sri Lankan hospitals: a cluster randomized controlled trial.

    Lalith Senarathna

    Full Text Available BACKGROUND: In developing countries, including Sri Lanka, a high proportion of acute poisoning and other medical emergencies are initially treated in rural peripheral hospitals. Patients are then usually transferred to referral hospitals for further treatment. Guidelines are often used to promote better patient care in these emergencies. We conducted a cluster randomized controlled trial (ISRCTN73983810 which aimed to assess the effect of a brief educational outreach ('academic detailing' intervention to promote the utilization of treatment guidelines for acute poisoning. METHODS AND FINDINGS: This cluster RCT was conducted in the North Central Province of Sri Lanka. All peripheral hospitals in the province were randomized to either intervention or control. All hospitals received a copy of the guidelines. The intervention hospitals received a brief out-reach academic detailing workshop which explained poisoning treatment guidelines and guideline promotional items designed to be used in daily care. Data were collected on all patients admitted due to poisoning for 12 months post-intervention in all study hospitals. Information collected included type of poison exposure, initial investigations, treatments and hospital outcome. Patients transferred from peripheral hospitals to referral hospitals had their clinical outcomes recorded. There were 23 intervention and 23 control hospitals. There were no significant differences in the patient characteristics, such as age, gender and the poisons ingested. The intervention hospitals showed a significant improvement in administration of activated charcoal [OR 2.95 (95% CI 1.28-6.80]. There was no difference between hospitals in use of other decontamination methods. CONCLUSION: This study shows that an educational intervention consisting of brief out-reach academic detailing was effective in changing treatment behavior in rural Sri Lankan hospitals. The intervention was only effective for treatments with

    Full Text Available Over the past few years much has been written about the rapid spread of various types of firm networking, the area of female entrepreneurs’ networks and small business entrepreneurship is still a challenging research field. This study aims to explore the role of female entrepreneurs’ networks and examine the importance influences for female entrepreneurs’ networking behaviour. Pilot studies are mostly under-reported in the qualitative research literature and this article specifically focuses on the pilot study findings.Having established that a qualitative methodology is most suitable for this study, the in-depth narrative interviews and observation are deemed a particularly suitable research tools. For this study, the pilot work was conducted in London prior to the main stage of data gathering in Sri Lanka. Five Sri Lankan migrant women entrepreneurs in London were purposively approached and interviewed.Findings show that the female entrepreneurs’ networking experience provides a valuable insight for developing their own small businesses. More specifically, majority of the female entrepreneurs emphasized the purpose- driven nature of their contacts and they organized their networks around the family and social domains rather than professional ties. Further, influences: competing family responsibilities and business matters (being a good mum, gender, trust and running home based business, are important and they affect networking behaviour of female entrepreneurs. This study adds to the extant literature through its two-dimensional focus on entrepreneurial networking .The structural dimension which investigates who are parts of the entrepreneurial networks; the relational side which explores the contributions each tie brings to the entrepreneurial venture. Further, it brings new evidence to bear by examine the importance influences for women networking behaviour by showing how the phenomenon of entrepreneurship is context specific and the

    The major threat for cassava cultivation on the Indian subcontinent is cassava mosaic disease (CMD) caused by cassava mosaic geminiviruses which are bipartite begomoviruses with DNA A and DNA B components. Indian cassava mosaic virus (ICMV) and Sri Lankan cassava mosaic virus (SLCMV) cause CMD in India. Two isolates of SLCMV infected the cassava cultivar Sengutchi in the fields near Malappuram and Thiruvananthapuram cities of Kerala State, India. The Malappuram isolate was persistent when maintained in the Madurai Kamaraj University (MKU, Madurai, Tamil Nadu, India) greenhouse, whereas the Thiruvananthapuram isolate did not persist. The recovered cassava plants with the non-persistent SLCMV, which were maintained vegetative in quarantine in the University of Basel (Basel, Switzerland) greenhouse, displayed re-emergence of CMD after a six-month period. Interestingly, these plants did not carry SLCMV but carried ICMV. It is interpreted that the field-collected, SLCMV-infected cassava plants were co-infected with low levels of ICMV. The loss of SLCMV in recovered cassava plants, under greenhouse conditions, then facilitated the re-emergence of ICMV. The partial dimer clones of the persistent and non-persistent isolates of SLCMV and the re-emerged isolate of ICMV were infective in Nicotiana benthamiana upon agroinoculation. Studies on pseudo-recombination between SLCMV and ICMV in N. benthamiana provided evidence for trans-replication of ICMV DNA B by SLCMV DNA A.

    Full Text Available Technology advancement has modified fundamentals of marketing theories, particularly the banking sector. Internet Banking has emerged as the most critical form of customer interaction, encompassing the structural changes required by the banks to compete within the financial markets. With the emergence of digital channels, banks are confronted with margin pressures and intense competition. In addition the customer’s quest for personalized services has intensified with the implementing of internet banking. Service quality is a pre-requisite for customer satisfaction and in a virtual environment the task becomes even more challenging to banks. Despite the explosive growth in internet banking globally, some countries still lag behind the implementation process. Security concerns persist as a salient feature and may be detrimental for the growth of the internet banking. In sequence with prior studies conducted in other countries, Corporate Image is envisioning as a control dimension of Service quality. The present study explores the decipherable antecedents of Customer satisfaction and the deviation in fundamentals, with the inclusion of Corporate Image, in the Sri Lankan Banking Sector.

    Full Text Available The global public health community is facing the challenge of emerging infectious diseases. Historically, the majority of these diseases have arisen from animal populations at lower latitudes where many nations experience marked resource constraints. In order to minimize the impact of future events, surveillance of animal populations will need to enable prompt event detection and response. Many surveillance systems targeting animals rely on veterinarians to submit cases to a diagnostic laboratory or input clinical case data. Therefore understanding veterinarians' decision-making process that guides laboratory case submission and their perceptions of infectious disease surveillance is foundational to interpreting disease patterns reported by laboratories and engaging veterinarians in surveillance initiatives. A focused ethnographic study was conducted with twelve field veterinary surgeons that participated in a mobile phone-based surveillance pilot project in Sri Lanka. Each participant agreed to an individual in-depth interview that was recorded and later transcribed to enable thematic analysis of the interview content. Results found that field veterinarians in Sri Lanka infrequently submit cases to laboratories--so infrequently that common case selection principles could not be described. Field veterinarians in Sri Lanka have a diagnostic process that operates independently of laboratories. Participants indicated a willingness to take part in surveillance initiatives, though they highlighted a need for incentives that satisfy a range of motivations that vary among field veterinarians. This study has implications for the future of animal health surveillance, including interpretation of disease patterns reported, system design and implementation, and engagement of data providers.

    There are several conditions giving rise to 46, XY disorders of sex development (DSD) with different modes of inheritance. Therefore definitive diagnosis based on molecular genetic confirmation would be the ideal to counsel parents regarding the future implications of the condition affecting their baby. This is the first report from Sri Lanka documenting the presence of mutations in the androgen receptor (AR) gene in a cohort of children with 46, XY DSD. To describe the socio-demographic and clinical features and document the presence of mutations in the androgen receptor (AR) gene in a cohort of children with 46, XY DSD. 46, XY patients with ambiguous genitalia followed up in the University Unit at the Lady Ridgeway Hospital, Colombo, and clinically identified as having androgen insensitivity syndrome (AIS) or a testosterone biosynthetic defect were recruited for the study. Their socio-demographic details and clinical features were documented. Exons 1 to 8 of the AR gene were screened for mutations by DNA sequencing on a venous blood sample. SRY gene mutations were also assayed. Thirty-four patients were studied, 3 of whom were clinically diagnosed as having complete androgen insensitivity syndrome (CAIS). Sex of rearing was female and male in 4 and 30 respectively. AR gene mutations were detected in 6 patients (17.6%). None of the patients had SRY gene mutations. Majority (88%) of the patients were raised as males. Six patients (17.6%) including the 3 with CAIS, had genetically confirmed AIS with the detection of AR gene mutations.

    Apparel exports bring in sizeable foreign income to Sri Lanka. To protect and promote this industry is a paramount need. This can be carried out by applying Human Factors/Ergonomics (HFE) which has proved to control negative effects at work places. This paper reports a case study which describes the demands and benefits of HFE in MAS Holdings which owns a large share of the apparel industry in Sri Lanka. The study consisted of walk through observation survey, a questionnaire survey and ergonomic work place analysis followed by a training programme to selected employees in three companies. Positive responses to questionnaires revealed good ergonomic practices in the work places surveyed. Ergonomically unfit chairs and potential hazards e.g. exposure to noise and hot environment were detected. It is seen that MAS have introduced strategies originated by Toyota Production System viz. 5S, Kaizen, six sigma etc., which are in fact ergonomic methods. A progressive project MAS boast of viz. 'MAS Operating System' (MOS) empowers training and development to employees. MAS Holdings has adequately realized the benefits of applying HFE as evident by the number of awards received. Relevant companies were advised to take appropriate corrective measures to control the potential hazards.

    Diabetes mellitus (DM) is a rapidly growing health concern in Sri Lanka. Diet and physical activity are important modifiable risk factors affecting the incidence, severity and management of DM. The present study aims to evaluate the knowledge and perceptions about dietary patterns and physical activity among a group of adults with DM in Sri Lanka using qualitative research methods. Fifty adults from a cohort of diabetic patients attending the medical clinics at the National Hospital of Sri Lanka were invited for the study. Data were collected via 10 Focus Group Discussions. Verbatim recording and documenting emotional responses were conducted by two independent observers. Directed content analysis of qualitative data was done with the help of NVIVO v10.0. Mean age was 61.2 ± 9.9 years and 46 % were males. Mean duration of diabetes was 10.4 ± 7.5 years. All were aware of the importance of diet in the management of DM. But most had difficulty in incorporating this knowledge into their lives mostly due to social circumstances. The majority described a list of 'good foods' and 'bad foods' for DM. They believed that 'good' foods can be consumed at all times, irrespective of quantity and 'bad' foods should be completely avoided. Many believed that fruits were bad for diabetes, while vegetables were considered as a healthy food choice. The majority thought that there were 'special' foods that help to control blood glucose, the most common being curry leaves and bitter-gourd. Most study participants were aware of the importance of being physical active. However, there was lack of consensus and clarity with regards to type, duration, timing and frequency of physical activity. Despite understanding the importance of dietary control and physical activity in the management of diabetes, adherence to practices were poor, mainly due to lack of clarity of information provided. There were many myths with regards to diet, some of which have originated from health care

  13. Mental health recovery and economic recovery after the tsunami: high-frequency longitudinal evidence from Sri Lankan small business owners.

    A sample of 561 Sri Lanka microenterprise owners affected to various extents by the December 2004 Indian Ocean tsunami were surveyed five times at quarterly intervals between March 2005 and April 2006. Mental health recovery was measured through questions on return to normalcy and change in life outlook. Business profits were used to measure livelihoods recovery. We find that these mental health process measures are correlated with post-traumatic stress disorder and general mental health in a validation survey, and display similar correlates to both in the cross-section. However, socioeconomic factors are not found to be significant in predicting the dynamics of mental health recovery in a fixed effects logistic regression. Mental health recovery from a given initial level therefore appears to depend largely on time since the disaster, and not on economic recovery of an individual's livelihood.

  14. Suicide and the 'Poison Complex': Toxic Relationalities, Child Development, and the Sri Lankan Self-Harm Epidemic.

    Widger, Tom

    2015-01-01

    Suicide prevention efforts in Asia have increasingly turned to 'quick win' means restriction, while more complicated cognitive restriction and psychosocial programs are limited. This article argues the development of cognitive restriction programs requires greater consideration of suicide methods as social practices, and of how suicide cognitive schemata form. To illustrate this, the article contributes an ethnographically grounded study of how self-poisoning becomes cognitively available in Sri Lanka. I argue the overwhelming preference for poison as a method of self-harm in the country is not simply reflective of its widespread availability, but rather how cognitive schemata of poison-a 'poison complex'-develops from early childhood and is a precondition for suicide schemata. Limiting cognitive availability thus requires an entirely novel approach to suicide prevention that draws back from its immediate object (methods and causes of self-harm) to engage the wider poison complex of which suicide is just one aspect.

    2005-04-01

    By combining economic analysis of markets with ecological parameters, this article considers the role that tourism-based sea turtle hatcheries (of an open-cycle type) can play in conserving populations of sea turtles. Background is provided on the nature and development of such hatcheries in Sri Lanka. The modeling facilitates the assessment of the impacts of turtle hatcheries on the conservation of sea turtles and enables the economic and ecological consequences of tourism, based on such hatcheries, to be better appreciated. The results demonstrate that sea turtle hatcheries serving tourists can make a positive contribution to sea turtle conservation, but that their conservation effectiveness depends on the way they are managed. Possible negative effects are also identified. Economic market models are combined with turtle population survival relationships to predict the conservation impact of turtle hatcheries and their consequence for the total economic value obtained from sea turtle populations.

    Abstract Anemia affects over 800 million women and children globally. Measurement of hepcidin as an index of iron status shows promise, but its diagnostic performance where hemoglobinopathies are prevalent is unclear. We evaluated the performance of hepcidin as a diagnostic test of iron deficiency in adolescents across Sri Lanka. We selected 2273 samples from a nationally representative cross‐sectional study of 7526 secondary schoolchildren across Sri Lanka and analyzed associations between hepcidin and participant characteristics, iron indices, inflammatory markers, and hemoglobinopathy states. We evaluated the diagnostic accuracy of hepcidin as a test for iron deficiency with estimation of the AUCROC, sensitivity/specificity at each hepcidin cutoff, and calculation of the Youden Index to find the optimal threshold. Hepcidin was associated with ferritin, sTfR, and hemoglobin. The AUCROC for hepcidin as a test of iron deficiency was 0.78; hepcidin outperformed Hb and sTfR. The Youden index‐predicted cutoff to detect iron deficiency (3.2 ng/mL) was similar to thresholds previously identified to predict iron utilization and identify deficiency in African populations. Neither age, sex, nor α‐ or β‐thalassemia trait affected diagnostic properties of hepcidin. Hepcidin pre‐screening would prevent most iron‐replete thalassemia carriers from receiving iron whilst still ensuring most iron deficient children were supplemented. Our data indicate that the physiological relationship between hepcidin and iron status transcends specific populations. Measurement of hepcidin in individuals or populations could establish the need for iron interventions. PMID:27883199

    Gamma-Aminobutyric acid (GABA), an important bioactive component of tea, acts as a major inhibitory neurotransmitter and is considered to influence other physiological processes in human as well as in planta. In the hereby presented study, the content of this valuable metabolite was investigated in two novel types of Ceylon Tea, explicitly "Silver Tips" and "White Tea", originating from minimally processed buds of the unique cultivar, "TRI 2043". The samples were subjected to hot water infusion, equivalent to the traditional beverage preparation procedure, and analyzed by means of hydrophilic interaction ultra performance liquid chromatography coupled to tandem mass spectrometry (HILIC LC-MS/MS). The registered GABA levels were compared with those obtained for the classic "Black Tea" and "Green Tea" samples from Sri Lanka. A high variation of GABA content was observed among the different tea types, especially in the case of "Silver Tips" and "White Tea", indicating the crucial influence of the manufacturing procedure (processing extent) on the final abundance of the bioactive component of interest. Furthermore, "White Tea" samples boasted the highest GABA concentration reported for this type of tea so far, reaching up to 50% of that characteristic of the high-priced "GABA Tea". Therefore, "White Tea" and "Silver Tips" were proved to be high quality tea with amounts of gamma-aminobutyric acid comparable with those described for similar types before. To our knowledge, this is the first report on HILIC LC-MS/MS application for the quantification of GABA and for in-depth characterization of teas from Sri Lanka.

    Sri Lanka is a resource-poor country in the South-East Asian region with good health indices. Ergonomics of children in educational environments is still novel in the region. An exploration into such issues and dissemination of the scientific evidence will stimulate policy makers in both education and health sector. An important ergonomic issue of the classroom is the seating arrangement. Essential aspects of seating include location of the chair and desk in relation to the blackboard and features of the chair and desk. Musculoskeletal pain is considered to be the most important negative effect due to mismatched ergonomics. A school-based descriptive cross sectional study was carried out in a district of Sri Lanka to ascertain the distribution of selected ergonomic factors related to seating arrangements in the classroom of school-going early adolescents and to assess their relationship to musculoskeletal pain. A sample of 1607 school children of Grade 6,7 and 8 were selected using stratified multi-stage cluster sampling method. There were 52.1% (N=838) females and 47.9% (N=769) males. Many ergonomic aspects related to classroom seating arrangements are not conducive for children. Children were seated with a mean distance of 398.04 cm (SD=132.09) to the blackboard. Nearly 23% of children had to turn more than 45~degrees to see the blackboard. A prevalence of > 80% mismatch was found between body dimensions of children and measurements of furniture. Musculoskeletal pain may have resulted from efforts to maintain stability while seated in incompatible furniture. Nearly 36% children complained of recurrent musculoskeletal pain. Musculoskeletal pain may have resulted from efforts to maintain stability while seated in incompatible furniture. Mismatched seat depth - buttock-popliteal length posed 1.59 times risk recurrent musculoskeletal pain. Despite, children perceived a good chair comfort. Use of backrest lowered the risk of recurrent pain. Results shows that

    Little is known about the prevalence of functional gastrointestinal diseases (FGDs) in adolescents, especially in developing countries. This cross-sectional survey conducted in a semi-urban school in Sri Lanka, assessed the prevalence of whole spectrum of FGDs in 427 adolescents (age 12-16 years) using a validated self-administered questionnaire. According to Rome III criteria, 123 (28.8%) adolescents had FGDs. Of them, 59 (13.8%) had abdominal-pain-related FGDs [irritable bowel syndrome (IBS) 30, functional dyspepsia 15, functional abdominal pain 13 and abdominal migraine 1]. Prevalence of functional constipation, aerophagia, adolescent rumination syndrome, cyclical vomiting syndrome and non-retentive faecal incontinence were 4.2, 6.3, 4, 0.5 and 0.2%, respectively. Only 58 (13.6%) adolescents were found to have FGDs when Rome II criteria were used. In conclusion, FGDs were present in more than one-fourth of adolescents in the study group, of which IBS was the most common. Rome III criteria were able to diagnose FGDs more comprehensively than Rome II.

    Epidemics of chronic kidney disease are now recognized in Central America, Mexico, India and Sri Lanka, and there is also some evidence that similar epidemics may be occurring in the USA, Thailand and elsewhere. A common denominator for each location is manually working outside in extremely hot environments. Here we review the evidence that the primary etiology may be heat stress related to repeated subclinical or clinical acute kidney injury that eventually manifests as chronic kidney disease. In some aspects, the disease may manifest as subclinical heat stroke, subclinical rhabdomyolysis or a subclinical tumor lysis syndrome. While toxins could be involved, it would be difficult to attribute this as a main mechanism, given the wide range of occupations and geographic regions manifesting this disease. While some of the epidemics may be due to better reporting, we believe the most important reasons are increasing heat extremes (heat waves) coupled with hydration with sugary or, less commonly, alcoholic beverages. © The Author 2017.

    Full Text Available In this millennium all the development activities are mostly focused on sustainable development, i.e. the development which fulfils the requirements of the present without disturbing the utilization of future generation. Basically, the sustainable development deals with environmental, social, and economical initiations. In relation to these three objectives, community participation plays a key role as an effective strategy for sustainable development. Among the numerous types of participation, Participatory Rural Appraisal (PRA technique is the most relevant effective method to receive the participation. Because, it has been strengthen by bottom up approach, well defined objectives, practicable solutions, and remedies. Hence, the out come of such an event is most productive rather than a top bottom approach techniques. In fact, a PRA was practiced to develop a strategic plan for tsunami affected village – Bambaranda east, in southern province of Sri Lanka. PRA sessions were carried out during February, 2007 by the Department of Agric. Economics of Ruhuna University, Sri Lanka in collaboration with Japanese Green Resource Agency, Japan.Participatory mapping, venn diagram, matrix ranking, preference ranking, and pair - wise ranking were demonstrated to gather information from the community. The tsunami affected area, including the paddy fields, four irrigation canals were shown by the group with the help of the participatory map. Preference ranking was resulted the reconstruction of irrigation canals as the most important rehabilitation activity to recover the livelihood of villagers. Intrusion of sea water into the paddy fields was the main limitation revealed by the pair - wise ranking. The second limitation marked as unavailability of enough fertilizer and the dilapidated irrigation canals was the third that has to be solved. Matrix ranking was employed to identify the most facilitated sectors by the government and other institutes in order

    The present work provides a detailed morphological and molecular description of Anoplocephala manubriata in elephants. Adult worms were recovered during an autopsy of a wild elephant in Elephant Transit Home, Udawalawe, Sri Lanka. Necropsy findings revealed a severe cestode infection in the small intestine. These tapeworms were tightly attached to the intestinal mucosae, resulted in hyperemic thickened intestinal mucosae, variable size irregular well-demarcated multifocal ulcerative regions sometimes covered with necrotic membranes and variable size, diffuse, well-demarcated raised nodular masses were evident in the small intestine. The article provides an account of the biology of A. manubriata and a comparative analysis of the morphology and morphometrics of Anoplocephala species that occur in different hosts. Phylogenetic analysis of the second internal transcribed spacer region (ITS-2), a portion of the 28S region and cytochrome oxidase subunit 1 (COX1) genes revealed that A. manubriata is closely associated with Anoplocephala species in horse in comparison to other Anoplocephalines. This study will enhance the current knowledge in taxonomy of elephant tapeworms and contribute to future phylogenetic studies. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Background: Male partners play an important and vital role in the decision-making process regarding pregnant women’s health. The purpose of the present study was to assess the knowledge and awareness of expectant fathers about Gestational Diabetes Mellitus (GDM, Pregnancy Induced Hypertension (PIH, and anaemia during pregnancy. Methods: A cross sectional descriptive study was carried out among expectant fathers whose partners were attending antenatal clinics at the Anuradhapura Teaching Hospital, Sri Lanka. All consenting participants were interviewed by investigators using an interviewer administered questionnaire to collect data on knowledge of risk factors, symptoms, complications and their control. Statistical analysis was performed using the Kruskal Wallis test.  Results: Of the 246 expectant fathers studied, 192 (78% were aware of GDM, 183 (74.4% and 154 (62.6% were aware of PIH and anaemia during pregnancy, respectively. The total number of answers provided by expectant fathers ranged from 0 to 33 (of 41 questions. There were 44 fathers who could not answer even a single question. For GDM, anaemia, and PIH, the percentages of expectant fathers who failed to provide at least a single correct answer were 24.8%, 40.2%, and 31.3%, respectively. The median number of total correct answers provided increased steadily along with the average income (chi-square 31.24, p<0.001 and educational level (chi-square 33.57, p<0.001. Expectant fathers in the 25-34 age group had significantly higher scores, compared to younger and older fathers (chi-square 15.11, p=0.001. Fathers experiencing the second pregnancy of their spouses also had higher scores. Conclusions: Expectant father’s knowledge of the selected morbidities was limited. To improve maternal health, any health promotional programmes should include expectant fathers.

    Armed conflicts and natural disasters are common. Millions of people, including children are killed, injured, disabled and displaced as a result. The effects of conflict and natural disaster on mental health, especially of children are well established but effects on education have received less attention. This study investigated associations between conflict and/or tsunami exposure in Sri Lanka and their associations with absenteeism in a national sample of school children. A cross-sectional survey was conducted in 2006-7 among 1,505 randomly selected school children aged 12-17 years attending government schools in 17 districts. The hypotheses were that absenteeism would be more common in children previously affected by conflict or the 2004 tsunami and that at least part of this effect would be accounted for by mental disorders. Survey information included socio-demographic, conflict and tsunami exposure, mental health status (Strengths and Difficulties Questionnaire) and information on absenteeism (defined as 20% or greater non-attendance over one year). The total sample of consisted of 1,505 students aged 12-17 years with a mean age of 13.7 years. 120 children reported at least one conflict exposure and 65 reported at least one tsunami exposure while only 15 reported exposure to both conflict and tsunami. Prevalence of emotional disorder caseness was 2.7%, conduct disorder caseness 5.8%, hyperactivity disorder caseness 0.6%, and 8.5% were identified as having any psychiatric disorder. Absenteeism was present in 26.8%. Overall, previous exposure to tsunami (OR 2.29 95% CI 1.36-3.84) was significantly associated with absenteeism whereas exposure to conflict was not (OR 1.32 95% CI 0.88-1.97), although some specific conflict-related exposures were significant risk factors. Mental disorder was strongly associated with absenteeism but did not account for its association with tsunami or conflict exposure. Exposure to traumatic events may have a detrimental effect on

Verified by David Heckard. Florida Museum of Natural History (UF 176422, photo voucher). New parish record. This species was first reported in the Americas in the vicinity of Audubon Zoo in New Orleans, Louisiana (Heckard et al. 2013. IRCF Reptiles & Amphibians 20:192–196). This is the third report of this species in Louisiana (Heckard et al. 2013, op. cit.; Borgardt 2015. Herpetol. Rev. 46:217), and is now documented from Orleans, Jefferson, and St. Tammany parishes in southeast Louisiana. The individual was located at night, ca. 10 m from a dwelling on the forest floor amid a downed picket fence, which was resting atop a thick layer of pine needles. There are H. turcicus at the property, but this individual was recognized as unusual, and many photos were taken before releasing the animal. It was not until much later that it was determined to be H. parvimaculatus. The origin of this individual is unknown, as the owners of this 1.62-ha property are elderly and do not keep any pets. Subsequent casual searches have not turned up any new individuals. I thank David Heckard for his help with identification and discussion of this species in Louisiana.

  13. Research-informed Outreach informs Research: Using games to inform and understand farmer decisions in Sri Lanka

    2016-12-01

    Researchers from the Agricultural Decision Making and Adaptation to Precipitation Trends in Sri Lanka (ADAPT-SL) team have been working for the past six years to understand Sri Lanka's agricultural vulnerability to climate change and how farmers and policy makers can adapt to and mitigate the variety of threats and uncertainties that climate change brings. In addition to academic publications, the compiled and developed knowledge from the ADAPT-SL research efforts are shared routinely with Sri Lankan stakeholders directly. While presentations are the norm for academic and government stakeholder outreach, we decided that an interactive component would increase farmers' learning. Drawing on teaching pedagogies, we designed a place-based, hands-on game that incorporated local climate and market characteristics to convey the impact of climate change on crop water needs for the Sri Lanka farmers. The process of developing the game, however, revealed gaps in our research knowledge, specifically regarding how farmers balance uncertainties associated with weather and market conditions. So we took advantage of the opportunity offered by the outreach effort to collect data; findings from the game led to the development of a system dynamics model. The game was well received by farmers and other Sri Lankan stakeholders in January 2016, with the former expressing that they played the game as if it was emulating actual farming decisions. The farmers also expressed a desire for more outreach efforts to be designed in such an interactive way. The game has since been used to engage U.S. students (from 5th grade to college seniors majoring in Sociology) regarding the complexities of tackling climate change issues.

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available This paper analyzes the causes of student political activism in Sri Lankan universities by paying attention to the history of student politics starting from the 1960s when the first traces of such activism can be traced. Towards this end, it makes use of the analytical framework proposed by David Finlay that explains certain conditions under which students may be galvanized to engage in active politics. Analyzing different socio-political contexts that gave rise to these movements, and the responses of incumbent governments to such situations, it concludes that in order to mitigate the risk of youth getting involved in violent politics, it is necessary to address larger structural issues of inequality.

    2014-08-01

    In 2009, a severe epidemic of dengue disease occurred in Sri Lanka, with higher mortality and morbidity than any previously recorded epidemic in the country. It corresponded to a shift to dengue virus 1 as the major disease-causing serotype in Sri Lanka. Dengue disease reached epidemic levels in the next 3 years. We report phylogenetic evidence that the 2009 epidemic DENV-1 strain continued to circulate within the population and caused severe disease in the epidemic of 2012. Bayesian phylogeographic analyses suggest that the 2009 Sri Lankan epidemic DENV-1 strain may have traveled directly or indirectly from Thailand through China to Sri Lanka, and after spreading within the Sri Lankan population, it traveled to Pakistan and Singapore. Our findings delineate the dissemination route of a virulent DENV-1 strain in Asia. Understanding such routes will be of particular importance to global control efforts.

    Full Text Available This study investigates the effects of equity ownership structure on financial performance of Sri Lankan listed businesses. Using dynamic panel generalised method of moment this study finds an inverse hump shape relationship between insider ownership and firm financial performance. The results of this study confirm that the effect of insider ownership on firm performance is more positive and significant where legal protection for investors is weak. It suggests that although new legislative reforms have been enacted, Sri Lankan companies are highly dependent on internal governance mechanisms. There is potential merit in promulgating new rules to control the expropriation of minority shareholders.

    Full Text Available Product harm crisis has become a serious issue in the business world today irrespective of the crisis mitigating strategies adopted to remedy the harm. The purpose of the study is to determine whether national culture shapes consumer reactions to crisis response strategies as a result of variation of consumers’ perceptions the affected firm’s moral responsibility. The study considers a comparison of 303 marketing-based Chinese and Sri Lankan students. Findings of independent sample t tests and Analysis of variance (ANOVA suggested that consumers’ moral perceptions vary significantly between China and Sri Lanka in response to crisis response strategies revealing a new insight in the crisis mitigating literature. A wounded company has to launch a super effort response in Sri Lanka whereas the voluntary recall response in China is sufficient in a crisis in order to maintain moral reputation. Moreover, the study reveals that implementation of an inappropriate strategy leads to significant financial and moral reputational loss to a company. Therefore, the study recommends companies choosing culture-specific response strategies in order to protect moral reputational status and to make the market sustainable.

    2013-12-01

    Full Text Available Following the Sri Lankan Government’s military defeat of the internationally proscribed terrorist organisation, the Liberation Tigers of Tamil Eelam (LTTE in May 2009, Sri Lanka embarked on an essential and long-term twofold post-conflict strategy: (i rehabilitation and reintegration of former LTTE combatants, and (ii the rebuilding of the conflict-affected Tamil communities of the Northern and Eastern Provinces. The rehabilitation program was by many counts a success, with demonstrated cognitive transformation in attitudes and behaviour of most of the (formerly radicalised combatants. Reconciliation initiatives were implemented to fulfill the urgent social, political, and economic needs of the conflict-affected communities of the North and East. These reconciliation efforts continue to be implemented and comprise different measures taken in: (1 resettlement and humanitarian assistance, (2 reconstruction of key transport, economic, health, and social infrastructure for reintegration, (3 political engagement, and (4 various types of peace-building work. Sri Lanka’s post-conflict strategy adopts a holistic approach, seeking the contribution of the public sector, private sector, community organisations, international organisations, NGOs, and private individuals from different segments of society in Sri Lanka. However, despite the many effective state-led and other reconciliation efforts undertaken by Sri Lanka, the author is able to present a number of recommendations to the government of Sri Lanka to overcome shortcomings in the rehabilitation and reconciliation programs adopted, as well as other challenges faced by Sri Lanka, such as the relentless disinformation campaign against the Sri Lankan state pursued by the remnant LTTE cells surviving internationally. To understand the complex nature of the Sri Lankan conflict and the skillful disinformation campaign pursued against the Sri Lankan state by the LTTE’s transnational network, a

    Full Text Available Pentasomy 49,XXXXY is a rare sex chromosome disorder usually presenting with ambigous genitalia, facial dysmorphism, mental retardation and a combination of cardiac, skeletal and other malformations. The incidence of the condition is estimated to be 1 in 85,000 male births. Previously, this condition was identified as a Klinefelter variant. The condition is suspected in a patient, by a combination of characteristic clinical findings, and the diagnosis is confirmed by chromosome culture and karyotyping. In the case we report here, the main presentation of ambiguous genitalia led to a suspicion of a sex chromosome aneuploidy which was subsequently confirmed by chromosomal analysis.

    Objective:To determine whether blood nitrite levels are elevated in patients with leptospirosis. Methods: Male patients fulfilling clinical and epidemiological criteria for a diagnosis of leptospirosis were recruited. Those with MAT titre of≥400 together with those seroconverting to a titer of≥200 were included in the analysis. Serum nitrite levels were measured in these patients and age, sex matched healthy controls. Results:Patients from 3 hospitals (n=75) were screened during a 3 month period from 28th June to 3rd September 2009, of whom 20 were eligible for the study. Serum nitrite levels were found to be significantly higher in patients with acute leptospirosis [n=20, (0.359±0.229)μM] compared to controls [(n=13,(0.216±0.051)μM] (P=0.014). A significant correlation was also observed between the MAT titre and the day of illness (r = 0.547; P<0.0001). Conclusions: Serum nitrite levels are higher in patients with acute leptospirosis compared to age and sex matched controls. No correlation could be assessed with severity of illness, as sample size was inadequate to determine this.

    Any system to compensate countries for reduced emissions from deforestation and forest degradation (REDD+) requires a historical reference level against which future performance can be measured. Here we examine the possibilities Sri Lanka, a small forest country with limited data on forest carbon stocks, has to get ready for REDD+. We construct a historical reference level using available forest inventory data combined with updated 2008 and 2009 in situ carbon density data for Sri Lankan forests. Furthermore, we use a combination of qualitative and quantitative data to attribute the clearing of Sri Lankan forests in the latest years for which national forest inventory data are available, 1992-1996, to various proximate drivers and to estimate the opportunity cost of forest conservation. We estimate that baseline deforestation emissions in Sri Lanka amounted to 17MtCO(2)yr(-1) in the 1992-1996 period, but conclude that it is challenging for Sri Lanka to produce a robust and accurate reference level due to the lack of nationally based inventories. We find that the majority of forest clearing (87%) is due to small-scale, rainfed farming, with the two other major drivers being rice and tea cultivation. Further, Sri Lankan revenues from REDD+ participation could be substantial, but they are sensitive to REDD+ policy transaction cost, highly uncertain timber revenues, and particularly the carbon price paid for emission reductions. The latter needs to be higher than $5-10/tCO(2) if there are to be substantial incentives for Sri Lanka to participate in REDD+. There is, however, a large gap in the knowledge of deforestation drivers that needs to be filled if Sri Lanka is to formulate an effective policy response to forest degradation in REDD+. For successful REDD+ implementation in Sri Lanka to happen, technological assistance, readiness assistance, and continued political momentum are crucial.

    As world population grows, there are ever increasing demands being placed on the food production systems throughout the world. Climate change is complicating these stressors even further through more frequent severe weather events. In the developing world, where there are fewer resources to mitigate the effects of climate change, the combination of these two factors can have drastic consequences. In Sri Lanka, farmers in major rice production areas of the country are already struggling to produce enough rice, a staple food of the local diet, and a severe wet or dry spell could be ruinous. Faced with a changing climate and a growing demand for rice, it is important to be able to anticipate how climatic changes will affect rice production. By examining how extreme wet and dry spells have historically affected rice production, decision makers may be better able to predict and prepare for potential food shortages. We conducted an analysis of historic temperature, precipitation, and rice production statistics in order to determine the effects of extreme wet and dry spells on rice production. We also created a timeline of major developments in Sri Lankan agriculture in order to compare effects on rice production due to changes in agricultural practices with meteorological changes. Historical temperature and precipitation data were used to calculate the Palmer Drought Severity Index (PDSI) for a number of stations distributed throughout the Mahaweli river basin. The basin, the largest in the country, contains three different climatic regions - dry, intermediate, and wet - that all receive different amounts of annual precipitation. The PDSI values were used to quantify drought and wetness during the Yala (April-September) and Maha (October-March) growing seasons. Analysis of historical PDSI values, agricultural advances, and rice production statistics shows great promise for anticipating and mitigating future food shortages.

    Full Text Available Although proclaimed as a democratic republic, the Sri Lankan state is strongly controlled and ruled by Sinhala Buddhist influence due to a deep engrained belief that the island belongs to the Sinhala Buddhists. The modus operandi of the Sri Lankan state apparatus outlines the ethnocratic characteristics of the state. This mono-ethnic and mono-religious attitude has led to the widening and deepening of the discrimination against a particular ethnic group known as the Tamils who traditionally inhabit the North and East of the island. Ethnocracy continues to be defended and justified by the state in the name of sovereignty, territorial integrity and national security and has led to further polarization of the already divided ethnic groups. As a consequence and outcome of the ethnocratic nature of the Sri Lankan state, a bloody war erupted between successive governments of Sri Lanka and the Liberation Tigers of Tamil Eelam (LTTE. After nearly 38 years the prolonged war came to a brutal end in May 2009 amidst blatant violations of international law. However, the root causes of this conflict, which occurred due to ethnocratic nature of the state, have not yet been addressed resulting in the continuation of the ethnic conflict despite the end of the war.

    Records on gallstones and associated ailments in Sri Lankan community are scarce, despite frequent detection of gallstone disease. Identification of the chemical composition of gallstones in the local setting is important in defining aetiopathogenic factors which in turn are useful in implementing therapeutic and preventive strategies. This study aimed to describe the chemical composition of gallstones and the socio-demographic factors of a cohort of Sri Lankan patients with gallstone disease. Data on clinical and socio-demographic factors, and gallstones removed at surgery were collected from patients with cholelithiasis admitted to Teaching Hospital, Peradeniya, Sri Lanka from May 2011 to December 2012. External and cross sectional morphological features of gallstones were recorded by naked eye observation. Compositional analysis was carried out by Fourier Transform Infrared Spectroscopy, X - ray Powder Diffraction, and Atomic Absorption Spectrophotometry. Scanning Electron Microscopy was used to identify the microstructure of gallstones. Data of 102 patients were analyzed. Of them majority (n = 77, 76%) were females with a female: male ratio of 3:1. Mean age of the study group was 46.1±11.6 years. All the patients had primary gallbladder stones. According to the physical and chemical analysis, majority (n = 54, 53%) were pigment gallstones followed by mixed cholesterol gallstones (n = 38, 37%). Only 10 (9%) had pure cholesterol gallstones. Calcium bilirubinate, calcium carbonate and calcium phosphate were the commonest calcium salts identified in pigment gallstones and core of mixed cholesterol gallstones. Presence of a pigment nidus in gallstones is a common feature in majority of Sri Lankan patients denoting the possible role of elevated unconjugated bilirubin in bile on the pathogenesis of GS. Hence it is imperative to explore this further to understand the aetiopathogenesis of GS among Sri Lankans.

    Women who migrate from Sri Lanka to become domestic workers in Lebanon face gender, class, and race discrimination that often results in abuse, yet the predicament of these women is largely ignored by local and international humanitarian and human rights agencies. Public consciousness about the plight of Asian domestic workers in the Persian Gulf region was raised in 1990 when domestic workers were repatriated in the wake of the Gulf War. In Lebanon, nearly half of the work permits granted to foreigners in 1997 were to women from Sri Lanka. This migration began in the 1970s and is sanctioned by the Sri Lanka government because of the economic benefits accruing from wages sent home by these women. Lebanese families procure domestic positions through an employment agency that arranges transportation and entry for the Sri Lankan women. These women, especially minors, often have to bribe Sri Lankan government agents to falsify travel documents. Upon arrival in Lebanon, the women have no support systems or job security. Most employment contracts last 3 years and pay $100/month with no benefits or protection from local labor laws. Domestic workers are made vulnerable by employers who withhold salaries or travel documents. Upon return to Sri Lanka, former domestic workers face social disapproval and marital problems. To redress this situation, the governments of sending and receiving countries must take action to protect female migrant workers, and nongovernmental organizations must publicize the plight of these women and take action to address the abuses they face.

    Full Text Available The apparel industry is a major export industry in Sri Lanka that depends upon labour intensive manufacturing. The Sri Lankan apparel industry is transitioning from Cut, Make, Trims (CMT assembly and Original Equipment Manufacturing (OEM to Original Design Manufacturing (ODM and Original Brand Manufacturing (OBM, experiencing the economic benefits of apparel product export. The transition relies on having expert professionals who can provide creative, commercial, technical, and leadership skills in the process. In order to identify the creative roles and responsibilities that can contribute to the industrial upgrading process in Sri Lanka, this paper first provides an analysis of the global apparel value chain and the journeys of the countries with newly industrialized economies (NIEs in the region. Second, a comparison of Hong Kong and Sri Lankan apparel industries contextualises the development of fashion design within each nation’s industry as a competitive advantage. In each country we examine three factors that demonstrate growth in fashion design: development of fashion design education; development of exportable own brands; and the establishment of local showcases to a global audience. The examples of both Hong Kong and Sri Lanka demonstrate the ways in which creative roles may act as a bridge between production and marketing networks, buyers and producers in maintaining and building industry value-adding for highly sophisticated and competitive fashion production systems. Although the Sri Lankan apparel industry has not progressed as far as Hong Kong in this arena, evidence suggests the industry is actively growing design capabilities

  4. The family and demographic change in Sri Lanka.

    Science.gov (United States)

    Caldwell, B

    Sri Lanka has almost completed the demographic transition with low mortality rates and fertility rates approaching replacement levels. Sri Lanka shares these characteristics with the South Indian states of Kerala and Tamil Nadu in contrast to elsewhere in South Asia where mortality and especially fertility rates remain much higher. A key part of the explanation for these differences lies in the nature of the family. The Sri Lankan family is essentially the conjugal unit of husband, wife and dependent children whereas in northern South Asia agnatic relations between son and parents are central to family structure. Related to this family system the position of women in Sri Lankan society was relatively high in South Asian terms. Consequently women had a strong say in health and fertility behaviour. When required, for example, mothers take the initiative in seeking health care for themselves and their children. Importantly family structure has facilitated female education which is associated with both mortality and fertility decline. There are few concerns that the values imparted by secular education are contrary to the values of the family or to women's roles within it. The egalitarian family structure has also contributed to fertility decline by raising the costs of children and reducing the long-run benefits to be gained from them. Sri Lanka is particularly distinctive in the contribution of changes in female age at marriage to its fertility decline, marriage age having risen six years this century. This change has been accompanied in recent times by a shift from family-arranged to self-selected (love) marriage. The explanation lies in changes in the socio-economic system which have reduced the centrality of the family in wider social and economic relations, and placed a greater premium on an individual's own abilities and attributes.

    Conclusions: Sri Lankans appear to be having a low incidence of prostate cancer, but a larger proportion of high-grade cancers in comparison to the UK and USA. Although genetic differences may exist, a dietary or an environmental factor is more likely to be the cause for these changes. The protective effect of this factor appears to wane as South Asians emigrate and live in UK and USA.

Through their interventions, humanitarian agencies affect the power...... relationship between state and non-state actors and between local organizations and the war-affected populations that make up their constituencies. But NGOs also affect the political order by introducing new understandings of the citizen and providing alternative moral arguments to legitimize power...

    Buddhist practices have been increasingly influencing psychotherapy. For over 20 centuries, Buddhism has been the religion of a majority of Sri Lankans. However, there is little documentation of the use of Buddhist practices in psychotherapy in Sri Lanka. This paper presents a case study in which Theravadan Buddhist mindfulness meditation and cognitive therapy practices were used in the treatment of a client with depressive disorder. The paper also summarizes the influence of Buddhist concepts and mindfulness meditation on psychotherapy and illustrate how Buddhist doctrine and practices can be considered a psychotherapeutic method.

    Diversity of the hypervariable regions (HV) I and II of the mitochondrial genome was studied in maternally unrelated Sri Lankans (N=202) from six ethnic groups (i.e.: Sinhalese, Sri Lankan Tamil, Muslim, Malay, Indian Tamil and Vedda). DNA was extracted from blood and buccal swabs and HVI and HVII regions were PCR amplified and sequenced. Resulting sequences were aligned and edited between 16024-16365 and 73-340 regions and compared with revised Cambridge reference sequences (rCRS). One hundred and thirty-five unique haplotypes and 22 shared haplotypes were observed. A total of 145 polymorphic sites and 158 polymorphisms were observed. Hypervariable region I showed a higher polymorphic variation than hypervariable region II. Nucleotide diversities were quite low and similar for all ethnicities apart from a slightly higher value for Indian Tamils and a much lower value for the Vedda population compared to the other groups. When the total population was considered South Asian (Indian) haplogroups were predominant, but there were differences in the distribution of phylo-geographical haplogroups between ethnic groups. Sinhalese, Sri Lankan Tamil and Vedda populations had a considerable presence of West Eurasian haplogroups. About 2/3rd of the Vedda population comprised of macro-haplogroup N or its subclades R and U, whereas macro-haplogroup M was predominant in all other populations. The Vedda population clustered separately from other groups and Sri Lankan Tamils showed a closer genetic affiliation to Sinhalese than to Indian Tamils. Thus this study provides useful information for forensic analysis and anthropological studies of Sri Lankans. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Water buffaloes are thought to be the reservoir hosts for several hemoprotozoan parasites that infect cattle. In the present study, we surveyed Sri Lankan bred water buffaloes for infections with Babesia bovis, Babesia bigemina, Theileria annulata, and Theileria orientalis using parasite-specific PCR assays. When 320 blood-derived DNA samples from water buffaloes reared in three different districts (Polonnaruwa, Mannar, and Mullaitivu) of Sri Lanka were PCR screened, B. bovis, B. bigemina, and T. orientalis were detected. While T. orientalis was the predominant parasite (82.5%), low PCR-positive rates were observed for B. bovis (1.9%) and B. bigemina (1.6%). Amplicons of the gene sequences of the Rhoptry Associated Protein-1 (RAP-1) of B. bovis, the Apical Membrane Antigen-1 (AMA-1) of B. bigemina, and the Major Piroplasm Surface Protein (MPSP) of T. orientalis were compared with those characterized previously in Sri Lankan cattle. While the B. bigemina AMA-1 sequences from water buffaloes shared high identity values with those from cattle, B. bovis RAP-1 sequences from water buffaloes diverged genetically from those of cattle. For T. orientalis, none of the MPSP sequence types reported previously in Sri Lankan cattle (types 1, 3, 5, and 7) were detected in the water buffaloes, and the MPSP sequences analyzed in the present study belonged to types N1 or N2. In summary, in addition to reporting the first PCR-based survey of Babesia and Theileria parasites in water buffaloes in Sri Lanka, the present study found that the predominant variants of water buffalo-derived B. bovis RAP-1 and T. orientalis MPSP sequences were different from those previously described from cattle in this country.

    Full Text Available This research was focused on the understanding of the biodegradability of synthetic anionic detergent powder available in Sri Lankan market. Eight different types of synthetic detergent powders were selected. LAS contents of the selected products were measured according to ASTM D 3049-89 standard. The biodegradability was measured as the reduction percentage of LAS initially present within a specific period. The phosphate content in the detergents were measured by SLS 760 1986 method and the pH of the media also was obtained to find any relationship between these parameters. The results found that the biodegradability of LAS in detergent powder is ranged between 24-79. This study found that the biodegradability of anionic surfactants highly depend on the phosphate content of the product. According to SLS 7601986 minimum LAS which has to be maintained in the Sri Lankan synthetic detergent and the existing legislations for the manufacturing marketing and consuming of detergent products should have modified for the health and safety environment. Therefore further studies need to be conducted to determine the maximum allowable level of phosphates lead to the highest level of biodegradability.

    Livestock is considered as one of the most important segments in agriculture since animal husbandry was practiced for centuries as a backyard system by rural families. Livestock plays as a powerful tool in rural development where meat industry contributes a dominant part. Meat and meat products become a vital component in the diet, which had been one of the main protein sources traditionally as well. The development in the livestock and meat industry of Sri Lanka basically depends upon religious, cultural, and economic factors. There is a growing demand for processed meat products in Sri Lankan urban culture and several large scale processors entered the business during the past few decades. The consumption of meat and meat products shows an upward trend in Sri Lanka during the last decade and is anticipated to increase further in future. The growth potential of the local meat industry is considerably high owing to the improvement of the market and consumer perception. The present status, trends, and future prospects for the Sri Lankan meat industry with respect to production, consumption, processing, marketing, and improvement are discussed in this review.

    Dogs can be infected by a wide range of Bartonella spp., but limited studies have been conducted in tropical urban and rural dog populations. We aimed to determine Bartonella antibody prevalence in 455 domestic dogs from four tropical countries and detect Bartonella DNA in a subset of these dogs. Bartonella antibodies were detected in 38 (8·3%) dogs, including 26 (10·1%) from Colombia, nine (7·6%) from Brazil, three (5·1%) from Sri Lanka and none from Vietnam. DNA extraction was performed for 26 (63%) of the 41 seropositive and 10 seronegative dogs. Four seropositive dogs were PCR positive, including two Colombian dogs, infected with B. rochalimae and B. vinsonii subsp. berkhoffii, and two Sri Lankan dogs harbouring sequences identical to strain HMD described in dogs from Italy and Greece. This is the first detection of Bartonella infection in dogs from Colombia and Sri Lanka and identification of Bartonella strain HMD from Asia.

    This paper draws on the experiences of the authors in designing and teaching a new course to educate speech and language therapists in Sri Lanka. This was the first speech and language therapist course in the country and was the result of collaboration between two universities, one in the UK and one in Sri Lanka. Rather than replicating established programmes elsewhere it was more appropriate to design a new course, suited to providing a comprehensive model of service, encompassing both social and medical approaches to rehabilitation. Issues about developing teaching and learning approaches to match pre-existing knowledge and experience of both staff and students are addressed. The particular ways of designing the programme to take account of cultural and language aspects of the Sri Lankan context are discussed.

  17. Butching it up: an analysis of same-sex female masculinity in Sri Lanka.

    Kuru-Utumpala, Jayanthi

    2013-01-01

    This paper seeks to examine the embodiment of female masculinity as experienced by 12 gender-non-conforming lesbians in Sri Lanka. By drawing on western feminist and queer theories, it critiques western theories in relation to a non-western subjectivity, attempting to unravel the seemingly empowering, albeit problematic, category of female masculinity. Data gathered through qualitative interviews address one key research question: how do gender-non-conforming lesbians in Sri Lankan embody female masculinity? As the discussion unfolds, this paper analyses the ways they view themselves, the extent to which their actions and behaviours fit within a masculine framework and the ways in which notions of desire are felt and understood in relation to their understanding of gender. In terms of theory, the analysis is located in social constructivist theory, while drawing on a postmodernist approach. Theoretically, the concept of female masculinity allows a woman embodying masculinity to dislodge men and maleness from it. The reality within a Sri Lankan experience, however, can at times be different, as this paper reveals.

    This study sought to identify those organizational health factors that might have overriding influence on the achievement level of students in science in Sri Lankan secondary schools. This study involved 752 students, 33 science teachers, and 10 principals from two different districts, Ampara and Colombo, in Sri Lanka. Ten Tamil medium, secondary level, public schools were selected to participate in this study. Data were collected using four types of instruments: a questionnaire for pupils; interview schedules for science teachers and principals; checklists for classroom/school facilities, science laboratory facilities, and science practicals; and a science achievement test. The analysis focused on the collective perceptions of students, science teachers, and principals. Regression and path analyses were used as major analysis techniques, and the qualitative data provided by science teachers and principals were considered for a crosschecking of the quantitative inferences. The researcher found teacher affiliation, academic emphasis, and instructional leadership of the principal, in descending order, were the overriding influential factors on the achievement level of students in science in Sri Lankan secondary schools. At the same time a similar descending order was found in their mean values and qualities. The researcher concluded that increasing the quality of the organizational health factors in Sri Lankan secondary schools would result in improved better achievement in science. The findings further indicate that instructional leadership of the principal had both direct and indirect effects on students' achievement in science when academic emphasis and teacher affiliation were taken into account. In addition, the resource support of the principal did not make any difference in students' science achievement and the findings stress the availability of the resources for individual students instead of assuming the general facilities of the school are available to all

    Introduction Food marketing is one of the main factors in the increase in childhood obesity. The objective is to compare the strategies used for promotion of food and beverages advertisements on Sri Lankan television for children and adults. Method Among 16 analog television channels in Sri Lanka, 50% of the channels were selected randomly after stratifying according to language. Recording was during weekdays and weekends. In total, 95 different food and beverages advertisements were analyzed irrespective of the channel. Results Among all food and beverages–related advertisements, 78% were child focused, and among these 74% claimed health benefits. A statistically significant difference was found in terms of implications related to nutrition or health (P < .05). None of the advertisements contained disclaimers. Conclusion and recommendations The Ministry of Health needs to pursue all food and beverages–focused advertisements for policy formulation and implementation. PMID:26658325

    Food marketing is one of the main factors in the increase in childhood obesity. The objective is to compare the strategies used for promotion of food and beverages advertisements on Sri Lankan television for children and adults. Among 16 analog television channels in Sri Lanka, 50% of the channels were selected randomly after stratifying according to language. Recording was during weekdays and weekends. In total, 95 different food and beverages advertisements were analyzed irrespective of the channel. Among all food and beverages-related advertisements, 78% were child focused, and among these 74% claimed health benefits. A statistically significant difference was found in terms of implications related to nutrition or health (P advertisements contained disclaimers. The Ministry of Health needs to pursue all food and beverages-focused advertisements for policy formulation and implementation. © 2015 APJPH.

    The story of the Sri Lankan Family Planning movement is told from its inception in 1953, prompted by a visit by Margaret Sanger 1952. The Family Planning Association of Sri Lanka was founded with the health of women and children, and both contraception and infertility treatment as its policies. The first clinic, called the "Mothers Welfare Clinic," treated women for complications of multiparity: one woman was para 26 and had not menstruated in 33 years. The clinic distributed vaginal barriers, spermicides and condoms, but the initial continuation rate was 5% year. Sri Lanka joined the IPPF in 1954. In 1959, after training at the Worcester Foundation, and a personal visit by Pincus, the writer supervised distribution of oral contraceptives in a pilot project with 118 women for 2 years. Each pill user was seen by a physician, house surgeon, midwife, nurse and social worker. In 1958 Sweden funded family planning projects in a village and an estate that reduced the birth rate 10% in 2 years. The Sri Lankan government officially adopted a family planning policy in 1965, and renewed the bilateral agreement with Sweden for 3 years. In 1968 the government instituted an integrated family planning and maternal and child health program under its Maternal and Child Health Bureau. This was expanded in 1971 to form the Family Health Bureau, instrumental in lowering the maternal death rate from 2.4/1000 in 1965 to 0.4 in 1984. During this period IUDs, Depo Provera, Norplant, and both vasectomy and interval female sterilizations, both with 1 small incision under local anesthesia, and by laparoscopic sterilization were adopted. Remarkable results were being achieved in treating infertile copies, even from the beginning, often by merely counseling people on the proper timing of intercourse in the cycle, or offering artificial insemination of the husband's semen. Factors contributing to the success of the Sri Lankan planned parenthood program included 85% female literacy, training of

    Carbapenemases are increasingly important antimicrobial resistance determinants. Little is known about the carbapenem resistance mechanisms in Sri Lanka. We examined 22 carbapenem-resistant Klebsiella pneumoniae from Sri Lanka to determine their β-lactam resistance mechanisms. The predominant resistance mechanisms we detected in this study were OXA-181, NDM-1 carbapenemases and extended-spectrum β-lactamase CTX-M-15. All isolates were then genotyped by pulsed-field gel electrophoresis, variable-number tandem repeat sequence analysis and multilocus sequence typing, and seven distinct genotypes were observed. Five OXA-181-positive Klebsiella pneumoniae isolates were genotypically related to an isolate of Indian origin. Multilocus sequence typing found that these related isolates belong to ST-14, which has been associated with dissemination of OXA-181 from the Indian subcontinent. Other genotypes we discovered were ST-147 and ST-340, also associated with intercontinental spread of carbapenemases of suspected subcontinental origin. The major porin genes ompK35 and ompK36 from these isolates had insertions, deletions and substitutions. Some of these were exclusive to strains within single pulsotypes. We detected one ompK36 variant, ins AA134-135GD, in six ST-14- and six ST-147, blaOXA-181-positive isolates. This porin mutation was an independent predictor of high-level meropenem resistance in our entire Sri Lankan isolate collection (P=0.0030). Analysis of the Sri Lankan ST-14 and ST-147 ins AA134-135GD-positive isolates found ST-14 was more resistant to meropenem than other isolates (mean MIC: 32±0 µg ml(-1) and 20±9.47 µg ml(-1), respectively, P=0.0277). The likely international transmission of these carbapenem resistance determinants highlights the need for regional collaboration and prospective surveillance of carbapenem-resistant Enterobacteriaceae.

    Full Text Available The Owner Driven Housing Assistance (ODHA scheme is a donor and government supported initiative to help construct housing for internally displaced persons (IDPs returning to their original areas of residence after the end of the Sri Lankan Civil War in 2009. While ODHA is a commendable initiative for rebuilding the lives of those displaced by war, available evidence indicates an increase in household debt among the beneficiaries of such housing schemes and their vulnerability to livelihood insecurities after resettlement. Based on an analysis of the socio-economic status of ODHA beneficiaries in the northern Sri Lankan districts of Mullaitivu, Kilinochchi and Jaffna, this paper concludes that the financing modality of the housing programme has had a catalytic effect on indebtedness among beneficiaries. An inadequate understanding of the social, economic and cultural contexts that define the lives of beneficiaries on the part of donors and implementers appears to be contributing to unintended and negative repercussions of housing assistance. This paper illustrates how post-war participatory development projects such as the ODHA scheme can further exacerbate the vulnerability of war-affected populations, unless donors and policy makers have a holistic understanding of the varying contexts that define the experiences of those receiving development assistance.

    Full Text Available Former British colony Ceylon (now Sri Lanka developed the University of Ceylon, Peradeniya as a model for the region. Its academic staff in the Social Sciences had their intellectual roots in the British or US traditions of scholarship due to their postgraduate training and research in these countries. Up to the early 1970s, there was a thriving academic atmosphere along with knowledge production and dissemination activities but this started to deteriorate with the socio-economic and political changes, changes in the language of instruction and the composition of the student body. A brain drain contributed to the creation of a different practitioner community of Anthropologists and Sociologists in the universities whose focus was more inward looking. Its links to Western traditions of scholarship also became weaker. Being a participant in this process from early 1970s up to the mid 1980s, the author uses his reflections and experiences to recount the changing nature of Anthropology and Sociology practice, theoretical emphasis, players involved, and the role of two research centres established outside the university system. The paper looks at the views of three Sri Lankan Anthropologists and Sociologists who have expressed concerns about the changing nature of teaching practices and constructed reality in Sri Lankan universities. The author connects these with the ongoing debate about Northern vs. Southern theory and prospects of alternative knowledge production articulated by Raewyn Connell.

    Full Text Available Shrimp farming has great potential to diversify and secure income in rural Sri Lanka, but production has significantly declined in recent years due to civil conflicts, some unsustainable practices and devastating outbreaks of disease. We examined management practices affecting disease prevention and control in the Puttalam district to identify extension services outputs that could support sustainable development of Sri Lankan shrimp farming. A survey on 621 shrimp farms (603 operational and 18 nonoperational was conducted within the Puttalam district over 42 weeks comprising a series of three-day field visits from August 2008 to October 2009, covering two consecutive shrimp crops. Fundamental deficits in disease control, management, and biosecurity practices were found. Farmers had knowledge of biosecurity but the lack of financial resources was a major impediment to improved disease control. Smallholder farmers were disproportionately constrained in their ability to enact basic biosecurity practices due to their economic status. Basic breaches in biosecurity will keep disease as the rate limiting step in this industry. Plans to support this industry must recognize the socioeconomic reality of rural Sri Lankan aquaculture.

    Purpose To investigate the incidence of bladder cancer (BC) in Sri Lanka and to compare risk factors and outcomes with those of other South Asian nations and South Asian migrants to the United Kingdom (UK) and the United States (US). Materials and Methods The incidence of BC in Sri Lanka was examined by using two separate cancer registry databases over a 5-year period. Smoking rates were compiled by using a population-based survey from 2001 to 2009 and the relative risk was calculated by using published data. Results A total of 637 new cases of BC were diagnosed over the 5-year period. Sri Lankan BC incidence increased from 1985 but remained low (1.36 and 0.3 per 100,000 in males and females) and was similar to the incidence in other South Asian countries. The incidence was lower, however, than in migrant populations in the US and the UK. In densely populated districts of Sri Lanka, these rates almost doubled. Urothelial carcinoma accounted for 72%. The prevalence of male smokers in Sri Lanka was 39%, whereas Pakistan had higher smoking rates with a 6-fold increase in BC. Conclusions Sri Lankan BC incidence was low, similar to other South Asian countries (apart from Pakistan), but the actual incidence is likely higher than the cancer registry rates. Smoking is likely to be the main risk factor for BC. Possible under-reporting in rural areas could account for the low rates of BC in Sri Lanka. Any genetic or environmental protective effects of BC in South Asians seem to be lost on migration to the UK or the US and with higher levels of smoking, as seen in Pakistan. PMID:22670188

    2016-07-01

    In the last two decades, chronic kidney disease of unknown etiology (CKDu) has emerged as a significant contributor to the burden of chronic kidney disease (CKD) in rural Sri Lanka. It is characterized by the absence of identified causes for CKD. The prevalence of CKDu is 15.1-22.9% in some Sri Lankan districts, and previous research has found an association with farming occupations. A systematic literature review in Pubmed, Embase, Scopus, and Lilacs databases identified 46 eligible peer-reviewed articles and one conference abstract. Geographical mapping indicates a relationship between CKDu and agricultural irrigation water sources. Health mapping studies, human biological studies, and environment-based studies have explored possible causative agents. Most studies focused on likely causative agents related to agricultural practices, geographical distribution based on the prevalence and incidence of CKDu, and contaminants identified in drinking water. Nonetheless, the link between agrochemicals or heavy metals and CKDu remains to be established. No definitive cause for CKDu has been identified. Evidence to date suggests that the disease is related to one or more environmental agents, however pinpointing a definite cause for CKDu is challenging. It is plausible that CKDu is multifactorial. No specific guidelines or recommendations exist for treatment of CKDu, and standard management protocols for CKD apply. Changes in agricultural practices, provision of safe drinking water, and occupational safety precautions are recommended by the World Health Organization.

    Full Text Available BACKGROUND AND AIMS: Snake bite is an important cause of mortality and morbidity in certain parts of Sri Lanka. This study was designed to determine the offending snakes, neurological manifestations, disease course, and outcome in neurotoxic envenomation. METHODS AND MATERIAL: Fifty six consecutive patients admitted with neurological manifestations following snake bite were studied prospectively. Data were obtained regarding the offending snakes, neurological symptoms, time taken for onset of symptoms, neurological signs, and time taken for recovery. RESULTS: The offending snake was Russell′s viper in 27(48.2%, common and Sri Lankan krait in 19(33.9%, cobra in 3(5.4%, and unidentified in 7(12.5%. Ptosis was the commonest neurological manifestation seen in 48(85.7% followed by ophthalmoplegia (75%, limb weakness (26.8%, respiratory failure (17.9%, palatal weakness (10.7%, neck muscle weakness (7.1%, and delayed sensory neuropathy (1.8%. Neurological symptoms were experienced usually within 6 hours after the bite. Following administration of antivenom, the signs of recovery became evident within a few hours to several days. The duration for complete recovery ranged from four hours to two weeks. CONCLUSIONS: Complete recovery of neuromuscular weakness was observed in all patients except for one who died with intracerebral haemorrhage shortly after admission.

    Huntington disease was one of the first neurological hereditary diseases for which genetic testing was made possible as early as 1993. The study describes the clinical and genetic characteristics of patients with Huntington disease in Sri Lanka. Data of 35 consecutive patients tested from 2007 to 2012 at the Human Genetics Unit, Faculty of Medicine, University of Colombo was analyzed retrospectively. Clinical data and genetic diagnostic results were reviewed. Statistical analysis was performed using descriptive statistics. Thirty patients had fully penetrant (FP) CAG repeat mutations and 5 had reduced penetrant (RP) CAG repeat mutations. In the FP group mean ages of onset and diagnosis were 37.5 and 40.4 years, while in the RP group it was 63.0 and 64.8 years respectively. The age of diagnosis ranged from 15 to 72 years, with 2 patients with Juvenile onset (60 years) Huntington disease. The symptoms at diagnosis were predominantly motor (32/35 -91%). Three patients had psychiatric and behavioral disorders. The age difference between onset and genetic diagnosis showed significant delay in females compared to males (p Huntington disease in the Sri Lankan study population were similar to that previously reported in literature.

  13. Sry is a transcriptional activator.

    The SRY gene functions as a genetic switch in gonadal ridge initiating testis determination. The mouse Sry and human SRY open reading frames (ORFs) share a conserved DNA-binding domain (the HMG-box) yet exhibit no additional homology outside this region. As judged by the accumulation of lacZ-SRY hybrid proteins in the nucleus, both the human and mouse SRY ORFs contain a nuclear localization signal. The mouse Sry HMG-box domain selectively binds the sequence NACAAT in vitro when challenged with a random pool of oligonucleotides and binds AACAAT with the highest affinity. When put under the control of a heterologous promotor, the mouse Sry gene activated transcription of a reporter gene containing multiple copies of the AACAAT binding site. Activation was likewise observed for a GAL4-responsive reporter gene, when the mouse Sry gene was linked to the DNA-binding domain of GAL4. Using this system, the activation function was mapped to a glutamine/histidine-rich domain. In addition, LexA-mouse Sry fusion genes activated a LexA-responsive reporter gene in yeast. In contrast, a GAL4-human SRY fusion gene did not cause transcriptional activation. These studies suggest that both the human and the mouse SRY ORFs encode nuclear, DNA-binding proteins and that the mouse Sry ORF can function as a transcriptional activator with separable DNA-binding and activator domains.

    This paper, based on World Health Organization and Sri Lankan sources, examines the attempts to control tuberculosis in Sri Lanka from independence in 1948. It focuses particularly on the attempt in 1966 to implement a World Health Organization model of community-orientated tuberculosis control that sought to establish a horizontally structured programme through the integration of control into the general health services. The objective was to create a cost- effective method of control that relied on a simple bacteriological test for case finding and for treatment at the nearest health facility that would take case detection and treatment to the rural periphery where specialist services were lacking. In the late 1940s and early 1950s, Sri Lanka had already established a specialist control programme composed of chest clinics, mass X-ray, inpatient and domiciliary treatment, and social assistance for sufferers. This programme had both reduced mortality and enhanced awareness of the disease. This paper exposes the obstacles presented in trying to impose the World Health Organization's internationally devised model onto the existing structure of tuberculosis control already operating in Sri Lanka. One significant hindrance to the WHO approach was lack of resources but, equally important, was the existing medical culture that militated against its acceptance.

    Migration has implications for women's sexual and reproductive health and rights. Our purpose with this study was to explore unmarried migrant women's perceptions of relationships and sexuality in the context of Sri Lankan Free Trade Zones. Sixteen semi-structured qualitative interviews were analyzed using thematic analysis. We found that the women's perceptions were influenced by gendered hegemonic notions of respectability and virginity. Complex gender relations both worked in favor of and against women's sexual and reproductive health and rights. Programs for improvement of migrant women's health should be informed by contextualized analysis of gender relations with its various dimensions and levels.

    The December 26, 2004 Sumatra-Andaman earthquake that registered a moment magnitude (M w ) of 9.1 was one of the largest earthquakes in the world since 1900. The devastating tsunami that resulted from this earthquake caused more casualties than any previously reported tsunami. The number of fatalities and missing persons in the most seriously affected countries were Indonesia - 167,736, Sri Lanka - 35,322, India - 18,045 and Thailand - 8,212. This paper describes two field visits to assess tsunami effects in Sri Lanka by a combined team of Japanese and Sri Lankan researchers. The first field visit from December 30, 2004 January 04, 2005 covered the western and southern coasts of Sri Lanka including the cities of Moratuwa, Beruwala, Bentota, Pereliya, Hikkaduwa, Galle, Talpe, Matara, Tangalla and Hambantota. The objectives of the first field visit were to investigate the damage caused by the tsunami and to obtain eyewitness information about wave arrival times. The second field visit from March 10 18, 2005 covered the eastern and southern coasts of Sri Lanka and included Trincomalee, Batticaloa, Arugam Bay, Yala National Park and Kirinda. The objectives of the second visit were mainly to obtain eyewitness information about wave arrival times and inundation data, and to take relevant measurements using GPS instruments.

    Endemic goitre has been reported in the climatic wet zone of south-west Sri Lanka for the past 50 years, but rarely occurs in the northern dry zone. Despite government-sponsored iodised salt programmes, endemic goitre is still prevalent. In recent years, it has been suggested that Se deficiency may be an important factor in the onset of goitre and other iodine deficiency disorders (IDD). Prior to the present study, environmental concentrations of Se in Sri Lanka and the possible relationships between Se deficiency and endemic goitre had not been investigated. During the present study, chemical differences in the environment (measured in soil, rice and drinking water) and the Se-status of the human population (demonstrated by hair samples from women) were determined for 15 villages. The villages were characterised by low (<10%), moderate (10-25%) and high (>25%) goitre incidence (NIDD, MIDD and HIDD, respectively). Results show that concentrations of soil total Se and iodine are highest in the HIDD villages, however, the soil clay and organic matter content appear to inhibit the bioavailability of these elements. Concentrations of iodine in rice are low ({<=}58 ng/g) and rice does not provide a significant source of iodine in the Sri Lankan diet. High concentrations of iodine (up to 84 {mu}g/l) in drinking water in the dry zone may, in part, explain why goitre is uncommon in this area. This study has shown for the first time that significant proportions of the Sri Lankan female population may be Se deficient (24, 24 and 40% in the NIDD, MIDD and HIDD villages, respectively). Although Se deficiency is not restricted to areas where goitre is prevalent, a combination of iodine and Se deficiency could be involved in the pathogenesis of goitre in Sri Lanka. The distribution of red rice cultivation in Sri Lanka is coincident with the HIDD villages. Varieties of red rice grown in other countries contain anthocyanins and procyanidins, compounds which in other foodstuffs are

    We live in a changing world - anthropogenic climate change is disrupting historic climate patterns and social structures are shifting as large scale population growth and massive migrations place unprecedented strain on natural and social resources. Agriculture in many countries is affected by these changes in the social and natural environments. In Sri Lanka, rice farmers in the Mahaweli River watershed have seen increases in temperature and decreases in precipitation. In addition, a government led resettlement project has altered the demographics and social practices in villages throughout the watershed. These changes have the potential to impact rice yields in a country where self-sufficiency in rice production is a point of national pride. Studies of the climate can elucidate physical effects on rice production, while research on social behaviors can illuminate the influence of community dynamics on agricultural practices. Only an integrated approach, however, can capture the combined and interactive impacts of these global changes on Sri Lankan agricultural. As part of an interdisciplinary team, we present an agent-based modeling (ABM) approach to studying the effects of physical and social changes on farmers in Sri Lanka. In our research, the diffusion of a sustainable farming technique, the system of rice intensification (SRI), throughout a farming community is modeled to identify factors that either inhibit or promote the spread of a more sustainable approach to rice farming. Inputs into the ABM are both physical and social and include temperature, precipitation, the Palmer Drought Severity Index (PDSI), community trust, and social networks. Outputs from the ABM demonstrate the importance of meteorology and social structure on the diffusion of SRI throughout a farming community.

    2015-07-01

    Full Text Available This paper examines the post-war Sri Lankan conditions among Sri Lanka Muslims, also known as Moors. The article will attempt to argue that state concessions to Muslim political leaders who supported the successive Sri Lanka’s ruling classes from independence through the defeat of the Liberation Tigers of Tamil Eelam (LTTE in 2009, have meant an isolation of the community from the other two main ethnic communities. The concessions that the Muslim community has won actively helped the Muslim community to be proactive in their religious practices and thus paved the way for exclusive social and political choices. The rise of Islamic movements and mosques in the post-1977 period galvanized Muslims. In time this isolation has been reinforced by socio-religious revival among Muslims whose ethnic identity has been constructed along the lines of the Islamic faith by Muslim elites. Despite this revival it has been clear that the Muslim community has been reluctant to use Islamic traditions and principles for peace building, which could have helped to ease tensions, brought about by the 30 year old ethnic conflict. On the other hand this paper will briefly discuss some reactions from the majority Sinhalese to Islamic revival as well as some issues between the Tamils and Muslims and the reintegration of Muslims in the North. Finally, some pragmatic ways to ease tensions between Muslims and non-Muslims in the greater discipline of conflict resolution are explored using traditions within Islam.

    Measuring chronic pesticide exposure is important in order to investigate the associated health effects. Traditional biological samples (blood/urine) are difficult to collect, store and transport in large epidemiological studies in settings such as rural Asia. We assessed the acceptability of collecting hair samples from a rural Sri Lankan population and found that this method of data collection was feasible. We also assessed the level of non-specific metabolites (DAPS) of organophosphate pesticides in the hair samples. The median concentration (pg/mg) of each DAP was: diethyl phosphate: 83.3 (IQI 56.0, 209.4); diethyl thiophosphate: 34.7 (IQI 13.8, 147.9); diethyl dithiophosphate: 34.5 (IQI 23.4, 55.2); and dimethyl phosphate: 3 (IQI 3, 109.7). Total diethylphosphates were recovered in >80% of samples and were positively correlated with self-reported pesticide exposure. PMID:26894816

    The first phylogenetic hypothesis for the Sri Lankan agamid lizard genus Ceratophora is presented based on 1670 aligned base positions (472 parsimony informative) of mitochondrial DNA sequences, representing coding regions for eight tRNAs, ND2, and portions of ND1 and COI. Phylogenetic analysis reveals multiple origins and possibly losses of rostral horns in the evolutionary history of Ceratophora. Our data suggest a middle Miocene origin of Ceratophora with the most recent branching of recognized species occurring at the Pliocene/Pleistocene boundary. Haplotype divergence suggests that an outgroup species, Lyriocephalus scutatus, dates at least to the Pliocene. These phylogenetic results provide a framework for comparative studies of the behavioral ecological importance of horn evolution in this group.

    Sri Lanka, an island country off the southeastern coast of India, populated by an estimated 16.1 million inhabitants, was one of the 1st developing countries to adopt a population policy aimed at reducing population growth and redistributing the population more equitably throughout the country. Population density is high. There are 636 persons/square mile, and 2/3 of the population lives in the southwestern and central regions of the country. Government redistribution policies seek to increase internal migration flows to the drier and less populated areas. The country's birth rate was 27 in 1982, the death rate was 6 in 1981, and the infant mortality rate was 34.4 in 1980. The rate of natural increase in 1982 was 2.1%, and the population growth rate declined from 2.5% prior to 1970 to 1.7% in 1980. The total fertility rate declined between 1963-74 from 5.0-3.4 and then increased to 3.7 in recent years. Given the age structure of the population, the population is expected to continue growing at a high rate in the coming years; however, the age at marriage is increasing and the proportion of young married women in the population is declining, and these trends will have an impact on population growth. These trends are due in part to increased educational and employment opportunities for women. The delay in marriage may also be linked to the dowry system. Given the high rate of poverty, it is difficult for parents to accummulate sufficient resources to provide dowries for their daughters. Sri lanka's economy is predominantly agricultural, with only 15% of the gross national product derived from manufacturing. Approximately 22% of thepopulation lives in urban areas. In 1981 exports totaled US$1.1 billion, and major export items were tea and rubber. In the same year, imports totaled US$1.8 billion and consisted primarily of food, petroleum, and fertilizers. The per capita gross national product was US$320 in 1982. Sri Lanka receives considerable foreign aid, and the

    Nutritional status of a population or an individual could be assessed by clinical,biochemical and anthropomet-ric means.It is widely used in the monitoring of growth and assessment of the nutritional status of children and adults.Even though a large number of anthropometric studies is done in Nepal and Sri Lanka,on various pro-jects related to the nutritional aspects,but only few have been done on anthropometry and due to lack of infor-mation on anthropometric data of Nepalese and Sri Lankan medical students,the present study was initiated at Nepal Medical college and Faculty of Medicine,University of Peradeniya,Sri Lanka.The aim of the study was to measure height and weight of medical students of Nepal Medical College and Faculty of Medicine,University of Peradeniya.A total of 1228 (males 681;females 547)medical students participated in the study.The ratio of male to female was 1.24:1.The height was measured,to the nearest 0.1 cm without shoes,using a measur-ing tape affixed to the wall.The weight was recorded using weighing scale,with minimum clothes and without shoes to the nearest 0.1kg.Two tail unpaired 't'test was performed to compare mean values.The percentile val-ues were obtained using Microsoft excel for Windows 98.The age of the students varied from 18-26 years with a mean ±SD of 20.77 ±1.17 and 20.90 ±1.10 in males and females respectively.The heights of the male and female medical students were1.65 ±0.08 and 1.61 ±0.08 and the weight was 59.70 ±9.26 and 55.54 ± 9.16 respectively.The percentile values obtained for height and weight were compared with National Centre for Health statistics (NCHS)standards.The 50th percentile value of male's height and weight corresponded to the 20th percentile and below the 20th percentile values respectively of the NCHS standard.The 50th percentile value of female's height and weight corresponded to less than 10th and 15th percentiles respectively.The height and weight of only 9 males and 8 females were above the

    In this study, we present an assessment of the Conformal Cubic Atmospheric Model (CCAM) 50 km simulations forced by the sea surface temperature and sea ice concentration of six global climate models (GCMs) (ACCESS1-0, CCSM4, GFDL-CM3, NorESM, MPI-ESM and CNRM-CM5) from the Coupled Model Inter-comparison Project Phase 5 (CMIP5) over South Asia, centred on Sri Lanka. The model simulations were compared with the data provided by the Asian Precipitation Highly Resolved Observational Data Integration towards Evaluation of Water Resource (APHRODITE) project and ERA-Interim from the European Centre for Medium range Weather Forecast (ECMWF) over a broad region centred on Sri Lanka. This broad region includes South Asia and northern Indian Ocean. Statistical measures such as pattern correlations, mean biases and root mean square errors were calculated separately for the four seasons. Results based on statistical tests indicate that the current CCAM simulations capture the spatial patterns of 10 m wind speed, mean sea level pressure, temperature and rainfall over a broad region over South Asia fairly well. The annual cycles of temperature and rainfall were also compared against observations over the northern and southern regions of Sri Lanka by taking the field average of each model and the observed data. The characteristics of the observed annual variations of rainfall and temperature over the smaller domains are not very well captured by the CCAM simulations. There are differences in the magnitudes of the temperature and rainfall in the six member CCAM simulations. Comparatively, the two CCAM simulations CNRM-CM5 and GFDL-CM3 show slightly better agreement over the Sri Lankan region.

    The aetiology of acute meningoencephalitis in Sri Lankan children and adults is poorly understood. This study was carried out to determine pathogens responsible for meningoencephalitis in Sri Lanka. A hospital-based cross-sectional study was performed using cerebrospinal fluid samples (22 adult and 17 pediatric) collected from August to December 2009 from patients clinically diagnosed with acute meningoencephalitis at two tertiary care hospitals in Sri Lanka. Routine microbiology for bacterial pathogens together with in-house RT-PCR and PCR assays for the detection of dengue viruses, Japanese encephalitis virus, West Nile virus, chikungunya virus, enteroviruses, mumps virus, measles virus, herpes simplex viruses types 1 and 2, and varicella zoster virus were performed. Bacterial pathogens were not isolated from any patient specimens. However, from nine of the paediatric patients aged 1 month to 10 years (mean age 5.2 years) echovirus 9 (E-9; family Picornaviridae, genus Enterovirus,species Enterovirus B ) was detected by RT-PCR. All nine patients presented with fever, six had headache, and seven had vomiting. Neck stiffness indicating meningitis was present in six of the patients. Phylogenetic analysis of partial VP1 and VP4-VP2 genes showed these E-9 strains to be most closely related to E-9 strains detected in CSF from Korea and France in 2005 and 2006. The remaining patients were negative for all other viruses tested. E-9 was the most common cause of acute meningoencephalitis in the tested paediatric population from Sri Lanka in 2009, which likely reflects circulation of this E-9 strain between Europe and Asia over several years. © 2015 Wiley Periodicals, Inc.

    The purpose of this retrospective study is to describe the pattern of bribe taking in exchange for release from torture, during and after the decades-long war in Sri Lanka. We reviewed the charts of 98 refugee claimants from Sri Lanka referred to the Canadian Centre for Victims of Torture for medical assessments prior to their refugee hearings in Toronto between 1989 and 2013. We tallied the number of incidents in which claimants described paying cash or jewelry to end torture, and collected other associated data such as demographics, organizations of the perpetrators, locations, and, if available, amounts paid. We included torture perpetrated by both governmental and nongovernmental militant groups. Collected data was coded and evaluated. We found that 78 of the 95 subjects (82.1%) whose reported ordeals met the United Nations Convention Against Torture/International Criminal Court definitions of torture described paying to end torture at least once. 43 subjects paid to end torture more than once. Multiple groups (governmental and non-governmental) practiced torture and extorted money by doing so. A middleman was described in 32 percent of the incidents. Payment amounts as reported were high compared to average Sri Lankan annual incomes. The practice of torture and related monetary extortion was still reported after the end of the war, inclusive of 2013. Torture in Sri Lanka is unlikely to end while profit motives remain unchallenged. As well as health injuries, victims of torture and their families suffer significant economic injuries while their assailants are enriched. The frequent link between torture and impunity means multiple populations the world over are vulnerable to this abuse.

    Full Text Available The effects of agronomic practices were evaluated on mungbean production, using a randomized complete block design conducted at the Farming Research Development Center, Phaniat sub-district, Khok Sumrong district, Lop Buri province, Thailand during February to July 2015. Five agronomic practices (each with four replications were tested—Thai farmer practice (TFP as the control; Thailand recommendation (TR; Sri Lankan farmer practice (SLFP; Sri Lankan new recommendation (SLNR; and Thailand recommendation with paddy straw mulch (TRM—each practice was composed of different tillage methods, seeding rates, mulching and seed inoculation (with Rhizobium. At the maturity stage, the lowest height (38.04 cm was found in TFP compared to 78.8%, 56.6%, 31.5% and 20.8% height increases reported in TRM, SLNR, SLFP, and TR, respectively. Furthermore, TFP had the lowest leaves per plant at maturity (8.73, whereas the percentage of leaves per plant at maturity in TR, SLFP, SLNR and TRM was 20.9%, 27.4%, 33.1% and 60.1%, respectively, higher than in TFP. TFP produced the lowest yield (0.657 t/ha while TRM, TR, SLFP and SLNR which produced increased yields by 109.13%, 41.4%, 46.1% and 86.8%, respectively, compared to the control. Overall, the results showed that the method of tillage, mulching and inoculum collectively determined the growth and seed yield of mungbean in a rice-mungbean cropping system.

    Hemoprotozoan parasites are responsible for significant economic losses in cattle. We screened Sri Lankan cattle populations for the presence of Babesia bovis, Babesia bigemina, Theileria annulata, and Theileria orientalis, using species-specific PCR assays. Out of 316 samples collected from animals in four different districts of Sri Lanka (Nuwara Eliya, Polonnaruwa, Ampara, and Jaffna), 231 (73.1%) were positive for at least one parasite species. All four parasite species were detected among the study groups from all of the districts surveyed. The first and second commonest hemoprotozoan parasites identified were T. orientalis (53.5%) and B. bigemina (30.1%), respectively. We found that the dry zones (Polonnaruwa, Ampara, and Jaffna) had more Babesia-positive animals than the hill country wet zone (Nuwara Eliya). In contrast, T. orientalis was the predominant species detected in Nuwara Eliya, while infection with T. annulata was more common in the dry zones. In addition, 81 (35.1%) of the 231 positive samples were infected with more than one parasite species. The presence of multiple parasite species among the different cattle populations is of clinical and economic significance. Therefore, island-wide control and prevention programs against bovine babesiosis and theileriosis are needed to minimize the financial burden caused by these parasites.

    Full Text Available The quality of the neighboring environment plays a major role in encouraging people to walk when attending their daily needs. Although past studies have identified a relationship between neighborhood design factors and the level of walkability, this interdependence is poorly understood in urban planning in Sri Lanka. The purpose of this study is to determine factors and conditions that influence walkability in a selected neighborhood in the town of Panadura and develop a model to predict what design factors enhance walkability in the neighborhood area. Ninety three (93 factors that affect the walkability in urban neighborhood were identified as the findings of the literature review of this study. Seventy six (76 walkability factors identified through perception surveys were examined within a 100m radius of 70 buffered circles representing 140 participants’ residences through a questionnaire survey and field observations. Chi-square and Bivariate correlation analysis were carried out to identify the most decisive factors for walkability. Multiple Linear Regression analysis was applied to develop a model to assess the level of walkability of residents in the selected area based on the most significant factors. The study has identified main nine variables that determine the level of walkability. Based on the significant values the model can be used to assess the level of walkability of the people in Sri Lankan context.

    Full Text Available Coconut (Cocos nucifera L. is a tropical palm offering multiple uses. Conservation of coconut germplasm has been undertaken globally in view of its economic importance. This research was designed to evaluate nine Sri Lankan indigenous coconut germplasm representing the three varieties Typica, Nana, and Aurantiaca. Total annual nut yield and the weights of fresh nut, husked nut, split nut, and fresh and dry kernel were scored and analyzed with analysis of variance. The annual average number of bunches varied from 14.9 to 16.8 which is significantly higher than the generally accepted 12–14 bunches in tall coconuts. The high potential of phenotypes Ran thembili and Gon thembili for kernel production was revealed. The high potential of Gon thembili, Sri Lanka Tall, and Ran thembili to produce fibre was also identified. Phenotypes Ran thembili and Gon thembili displayed their potential as pure cultivars and as parents in hybridization. King coconut, Red dwarf, and Bodiri were shown to be suitable as beverage coconuts due to the high production of nuts, bunches, and the quantity of nut water. This study reiterated the importance of conservation and characterization of indigenous coconut varieties globally for their effective use in the genetic improvement of the coconut palm.

    2013-02-01

    Full Text Available Prior to the conclusion of 30 years of civil war, many ordinary Sri Lankans were caught in bombings intended to disrupt daily life. This occurred not only in the war zone, but also in urban areas, primarily the capital of Colombo. While many lost their lives, others survived – scarred, disabled and traumatised. This chapter explores the meaning of ‘survival’ as experienced in newly-formed role of ‘bomb victim’. In doing so, this chapter questions the capacity of survivors to be productive as breadwinners and/or deal with the severe economic dislocations resulting from the drastic changes in their lives’ trajectories. Overall, the chapter finds that the loss of income and inability to fully participate in the market economy isolating the survivors from the main discourses of development, and purported opportunities offered therein. The end of hostilities has marked a clear drive to develop Sri Lanka, and in this important post-war stage, it is important to note the various ways in which religion is used to address survival needs. This chapter thus highlights the dynamic interplay between religion, political violence and development. In doing so, the chapter examines religious responses to (neo liberal, market-driven globalisation, the experience of terror and violence, and the interaction thereof.

    Full Text Available Abstract Background Non-alcoholic fatty liver disease (NAFLD is recognized as a metabolic disorder largely seen in urbanized populations. The purpose of this study was to assess prevalence and risk factors for NAFLD in a rural, physically active, economically deprived population in Sri Lanka. Methods By visiting individual households in the community, 35-64 year old adults resident in two selected estates in the Nuwara Eliya District of Sri Lanka, were invited to participate in the study. Blood pressure and anthropometric measurements were made on all participants. Blood samples were obtained for the assay of fasting glucose, serum lipids, serum insulin and alanine aminotransferase. NAFLD was diagnosed on established ultrasound criteria for fatty liver in the absence of hepatitis B and C markers and high alcohol consumption. Results Of those invited, 403 (65% participated in the study. Almost all participants were either Indian or Sri Lankan Tamils and 53% were females. Prevalence of NAFLD was 18% in this population. Twice as many males were diagnosed as having NAFLD compared to females. Male sex, high BMI, high waist circumference, high diastolic blood pressure and high plasma glucose levels were significant predictors of NAFLD. Conclusion Nearly one in five people in this predominantly Indian Tamil, rural, physically active, economically deprived population had NAFLD. The condition was associated with constituent features of the metabolic syndrome. These results support studies reporting ethnic variations in disease susceptibility and suggest that genetic factors may also play a role in determining disease risk.

    Chronic kidney disease of unknown (“u”) cause (CKDu) is a growing public health concern in Sri Lanka. Prior research has hypothesized a link with drinking water quality, but rigorous studies are lacking. This study assesses the relationship between nephrotoxic elements (namely arsenic (As), cadmium (Cd), lead (Pb), and uranium (U)) in drinking water, and urine samples collected from individuals with and/or without CKDu in endemic areas, and from individuals without CKDu in nonendemic areas. All water samples – from a variety of source types (i.e. shallow and deep wells, springs, piped and surface water) – contained extremely low concentrations of nephrotoxic elements, and all were well below drinking water guideline values. Concentrations in individual urine samples were higher than, and uncorrelated with, those measured in drinking water, suggesting potential exposure from other sources. Mean urinary concentrations of these elements for individuals with clinically diagnosed CKDu were consistently lower than individuals without CKDu both in endemic and nonendemic areas. This likely stems from the inability of the kidney to excrete these toxic elements via urine in CKDu patients. Urinary concentrations of individuals were also found to be within the range of reference values measured in urine of healthy unexposed individuals from international biomonitoring studies, though these reference levels may not be safe for the Sri Lankan population. The results suggest that CKDu cannot be clearly linked with the presence of these contaminants in drinking water. There remains a need to investigate potential interactions of low doses of these elements (particularly Cd and As) with other risk factors that appear linked to CKDu, prior to developing public health strategies to address this illness. - Highlights: • Drinking water in rural Sri Lanka contains low levels of inorganic nephrotoxicants • Urinary nephrotoxicants are consistent with reference levels from

    Full Text Available Abstract Background Endometriosis is characterized by the persistence of endometrial tissue in ectopic sites outside the uterine cavity. Presence of nickel, cadmium and lead in ectopic endometrial tissue has been reported previously. While any association between blood levels of nickel and endometriosis is yet to be described in literature, conflicting reports are available with regards to cadmium and lead levels in blood and urine. Findings In fifty patients with endometriosis and fifty age-matched controls confirmed by laparoscopy or laparotomy, whole blood samples were collected and digested using supra pure 65% HNO3. Whole blood levels of nickel and lead were measured using Total Reflection X-ray Fluorescence (TXRF while cadmium levels were evaluated using graphite furnace atomic absorption spectroscopy (GFASS. Women with endometriosis had significantly higher (P=0.016 geometric mean (95% CI whole blood nickel levels [2.6(1.9-3.3 μg/L] as compared to women without endometriosis [0.8 (0.7-0.9 μg/L]. Whole blood levels of cadmium and lead were similar between the two groups. Conclusions Although women with endometriosis in this study population had higher levels of nickel in whole blood compared to controls, whether nickel could be considered as an aetiological factor in endometriosis remains inconclusive in view of the smaller sample that was evaluated.

    We aimed to study the prevalence and associations of suboptimal high density lipoproteins level, a characteristic feature in diabetic dyslipidemia among patients under statin therapy. From a database of 2416 patients, data on age, gender, duration of diabetes, body mass index (BMI) and waist circumference (WC), low density lipoproteins (LDL), triglyceride, high density lipoproteins (HDL) were obtained. Prevalence of suboptimal HDL (diabetes, BMI and WC were studied. The mean (SD) age of the sample (n=2416) was 53 (10) years and 64.2% of them (n=1550) were males. Prevalence of suboptimal HDL was 17.6%. Regression analysis revealed female gender, (OR 7.73, 95% CI 5.99-9.97) younger age (OR 0.98, 95% CI 0.97-0.99), higher BMI (OR1.05. 95% CI 1.00-1.2) and LDL level over 100mg/dL (OR 1.004, 95% CI 1.00-1.007) had significant associations with suboptimal HDL. Every sixth diabetic patient on statins has suboptimal HDL level. Females, younger and obese diabetic individuals should be more focused on achieving optimal HDL cholesterol levels.

    Full Text Available Abstract Background Dental caries among young children are a global problem. Scant attention is paid towards primary teeth, leading to high prevalence of dental caries. There are only few studies done in Sri Lanka, addressing oral hygiene among preschool children. Scientific evidence is in need to persuade authorities to establish a programme promoting oral hygiene among preschool children. Methods A descriptive cross sectional study was conducted in Ragama Medical officer of Health area. Consecutive children between 2 – 5 years of age, attending child welfare clinics were recruited for the study. Practices related to dental hygiene and socio-economic characteristics were obtained using an interviewer administered questionnaire. Mouth was examined for evidence of dental caries. Data collection and examination were done by two doctors who were trained for this purpose. The data were analysed using SSPS version 16. Results Total of 410 children were included. None had a routine visits to a dentist. Practices related to tooth brushing were satisfactory. Prevalence of dental caries gradually increased with age to reach 68.8% by 5 years. Mean total decayed-extracted-filled (deft score for the whole sample was 1.41 and Significant caries index (SIC was 4.09. Decayed tooth were the main contributor for the deft score and Care index was only 1.55. Girls had a significantly higher prevalence of caries than boys. Conclusions Dental care provided for Sri Lankan preschool children appears to be unsatisfactory as prevalence of dental caries among this cohort of preschool children was very high. There is an urgent need to improve dental care facilities for Sri Lankan preschool children.

    Full Text Available Sri Yantra is one of the most auspicious, important and powerful Yantras, which not only gives the maximum benefit, but also proves beneficial for almost everybody. The traditional methods for drawing Sri Yantra are complex. It is very difficult to obtain Sri Yantra with full accuracy. The objective of this study is to define algorithmic approach for generating Sri Yantra with maximum accuracy. The accuracy is measured through the parameters like Concurrency, Concentricity and Equilateral. It is the source of attaining all worldly desires and fulfilling all wishes through inner cosmic power and mental strength. "Sri Yantra" - Sri means wealth and Yantra-means "Instrument"-"The Instrument for Wealth". The Instrument for Wealth the Sri Yantra brings about material and spiritual wealth Sri Yantra blesses the worshiper with peace, happiness, popularity, power, authority, wealth, prosperity and success. Leaders and men in authority should use this Yantra for attaining fame, power and financial benefits. Sri Yantra is definitely the answer to all the problems and negativity in our life. Existing edition of seven by seven grids had erroneous descriptions Sri Yantra, according to the latest English translation. Unfortunately, that one two is marred with errors in diagrams and unclear reference to inside-out construction instructions for the drawing of the triangular central pattern. There is no systematic approach to draw a traditional Sri Yantra. The methods used to generate Yantra in previous studies are approximate and not producing accurate design. This study presents a clear algorithmic approach to construct the Sri Yantra. This study mainly focuses to produce highest level of accuracy and construct the optimal configuration of Sri Yantra.

  4. Identify Current Deficiencies in Public Private Partnership Practices and Areas which Resist PPP Being an Attractive Investment Model in Infrastructure Developments – Case Study from Sri Lanka

    W. S. L. Perera

    2016-08-01

    Full Text Available Public- Private Partnerships is becoming a popular investment model since late 1980s and 1990s in the world. PPPs in the delivery of public services have become a phenomenon which is spreading around the globe and generating great interest among governments, investors and other key project stakeholders. Public- Private Partnerships avoid the often negative effects of either exclusive public ownership or outright privatization. This is seen as a win-win situation for both public and private entities where they undertake large scale projects. This balanced approach is especially welcomed in public services which touch on every human being‟s basic needs & economic development of a country. Basically in this research, it is attempted to address three main objectives, which are to identify the current Public- Private Partnerships coverage on infrastructure projects in Sri Lanka, to identify current deficiencies in Public- Private Partnerships practices and areas which resist Public- Private Partnerships being an attractive investment model in infrastructure developments in Sri Lankan context and to propose an improved PublicPrivate Partnerships framework/model that can be used effectively and address the identified problems in infrastructure developments in Sri Lanka. Based on a structured questionnaire, data collection has been done using a selected sample. Then, the data set has been evaluated using Likert Scale and giving weights for that and the total percentage of score. Lack of the knowledge and deficiencies of the PPP framework are main issues in PPP practice in Sri Lanka. Thus, it is not much popular investment model to infrastructure development at the moment. Further the government should change their role from developer and operator to facilitator to improve the PPP practice in Sri Lanka

    Since the economic liberalization in 1977, a large number of Sri Lankan women have entered the labour market and engaged in income-generating activities. Some women choose to travel abroad as domestic workers, while others choose to work in export-processing industries. This process has a profound impact on gender and gender roles in Sri Lanka. Young rural women have changed their traditional women's roles to become independent daughters, efficient factory workers and partially modernized women. Even though changing gender roles are identified as a positive impact of industrial work, the new social, cultural, and legal environments of industrial work have negative impacts on these women's lives. This paper explores health impacts of changing gender roles and practices of young rural women, focusing on the experiences of female workers in export-processing industries. Further, it contributes to the literature on gender and health, and on qualitative approaches within health geographic studies. A model is formulated to suggest a conceptual framework for studying women's health. The model describes the determinant factors of individual health status based on the question of who (personal attributes) does what (type of work) where (place), when and how (behaviours). These are also determinant factors of gender and gender roles of a society. The three types of health problems (reproductive, productive and mental health) of a woman, in this case a female industrial worker, are determined by her gender roles and practices associated with these roles.

    To deliver and evaluate a short critical care nurse training course whilst simultaneously building local training capacity. A multi-modal short course for critical care nursing skills was delivered in seven training blocks, from 06/2013-11/2014. Each training block included a Train the Trainer programme. The project was evaluated using Kirkpatrick's Hierarchy of Learning. There was a graded hand over of responsibility for course delivery from overseas to local faculty between 2013 and 2014. Sri Lanka. Participant learning assessed through pre/post course Multi-Choice Questionnaires. A total of 584 nurses and 29 faculty were trained. Participant feedback was consistently positive and each course demonstrated a significant increase (p≤0.0001) in MCQ scores. There was no significant difference MCQ scores (p=0.186) between overseas faculty led and local faculty led courses. In a relatively short period, training with good educational outcomes was delivered to nearly 25% of the critical care nursing population in Sri Lanka whilst simultaneously building a local faculty of trainers. Through use of a structured Train the Trainer programme, course outcomes were maintained following the handover of training responsibility to Sri Lankan faculty. The focus on local capacity building increases the possibility of long term course sustainability. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Chronic kidney disease of unknown ("u") cause (CKDu) is a growing public health concern in Sri Lanka. Prior research has hypothesized a link with drinking water quality, but rigorous studies are lacking. This study assesses the relationship between nephrotoxic elements (namely arsenic (As), cadmium (Cd), lead (Pb), and uranium (U)) in drinking water, and urine samples collected from individuals with and/or without CKDu in endemic areas, and from individuals without CKDu in nonendemic areas. All water samples - from a variety of source types (i.e. shallow and deep wells, springs, piped and surface water) - contained extremely low concentrations of nephrotoxic elements, and all were well below drinking water guideline values. Concentrations in individual urine samples were higher than, and uncorrelated with, those measured in drinking water, suggesting potential exposure from other sources. Mean urinary concentrations of these elements for individuals with clinically diagnosed CKDu were consistently lower than individuals without CKDu both in endemic and nonendemic areas. This likely stems from the inability of the kidney to excrete these toxic elements via urine in CKDu patients. Urinary concentrations of individuals were also found to be within the range of reference values measured in urine of healthy unexposed individuals from international biomonitoring studies, though these reference levels may not be safe for the Sri Lankan population. The results suggest that CKDu cannot be clearly linked with the presence of these contaminants in drinking water. There remains a need to investigate potential interactions of low doses of these elements (particularly Cd and As) with other risk factors that appear linked to CKDu, prior to developing public health strategies to address this illness.

    Full Text Available Editor’s note: This paper is a contribution to the ‘Policy Debate’ section of International Development Policy. In this section, academics, policy-makers and practioners engage in a dialogue on global development challenges. Papers are copy-edited but not peer-reviewed. Instead, the initial thematic contribution is followed by critical comments and reactions from scholars and/or policy-makers.Authored by Norah Niland, the initial paper addresses the protection dimension of humanitarian action in the Sri Lankan Civil War. The end phase of this long-standing war and subsequent internment of survivors illustrate the limited capacity of the international relief system to adequately protect civilians. The author argues that the failure of intergovernmental crisis management and the human rights machinery was exacerbated by the relief system’s lack of agency in safeguarding humanitarian space and the protected status of civilians. According to Norah Niland, relief actors largely ignored the instrumentalisation of humanitarianism and the use of sovereignty and Global War on Terror (GWOT narratives to rationalise the slaughter of thousands. The lack of accountability for and reflection on the humanitarian  operation  in Sri Lanka will likely complicate future relief efforts and add to the suffering of  civilians in other crisis settings. The paper  is followed by critical comments by Sir John Holmes, Former UN Under-Secretary General and Emergency Relief Coordinator, Head of the UN Office for the Coordination of Humanitarian Affairs, and Miriam Bradley, Postdoctoral Researcher, Programme for the Study of International Governance, the Graduate Institute, Geneva.This debate can be pursued on the eJournal’s blog http://devpol.hypotheses.org/69Download the full debate in .pdf

    Metabolic syndrome (MetS) is a significant predictor of cardiovascular diseases (CVDs). A pretested questionnaire was used to assess knowledge, attitudes, and practice (KAP) of CVD and its risks among Sri Lankan urban adults (35-55 years) with MetS. KAP scores were predefined as high, moderate, and low. Of the participants (n = 423), 13% were males and 87% were females. Attitudes scores were high among this population, though their knowledge and practices scores on CVD risk factors were moderate. Participants with high mean knowledge scores had significantly lower waist circumference (WC) and showed a trend toward reduced fasting blood glucose levels. Participants with high practice scores had significantly lower BMI and WC, which signify that better knowledge and practices are associated with decrease in CVD risk markers in these patients. The study reveals that urban MetS patients have a moderate knowledge and practice score, though their attitude score is high regarding CVD risk factors. © 2015 APJPH.

    Hotspots project of the Earth Institute at Columbia University. We developed tools that translate meteorological, environmental and socio-economic exposure and vulnerability information into assessments of relevant hazard related disaster risk at appropriate spatial and temporal scales. We also developed high-resolution predictive capabilities for assessing seasonal hazard event. We found that useful hazard risk and vulnerability analysis can be carried out with the type of data that is available in Sri Lanka with sufficiently fine scale as to be useful for national level planning and action. Also, hydro-meteorological information was essential to estimate hazard risks. This analysis brought out a distinct seasonality to drought, floods, landslides and cyclone hazards in Sri Lanka. This work provides a foundation for systematic disaster management that shall manage risks through measures such as hazard warnings, scenario-based relief identification and planning, strategic river basin management, risk mapping and land use zoning, standards for construction and infrastructure. The fostering of research and application capacity in the vulnerable community leads to the appropriate and sustainable use of earth science information. This work contributes to the mitigation of risk of vulnerable communities and provides an example of the harnessing of geosciences for poverty alleviation and improvement of human well-being.

    The production and use of polychlorinated biphenyls (PCBs) have ceased and most developed countries have disposed off their stocks long time ago. PCBs can however still be found in the environment and one important source is accumulated stocks in developing countries. Sound treatment of PCB is costly and most developing countries do not have dedicated hazardous waste incinerators or non-combustion technologies available for domestic disposal and can usually not afford export. High temperature cement kilns have been used to treat organic hazardous wastes in developed countries for decades and shown to constitute a sound option if well managed and controlled. In contrast to dedicated hazardous waste incinerators and other treatment techniques, cement kilns are already in place in virtually every country and may constitute a treatment option. The objective of this study was therefore to carry out the first test burn with PCB-oil in a developing country cement kiln and to assess its feasibility and destruction performance. The 3 d test burn demonstrated that the Sri Lankan cement kiln was able to destroy PCB in an irreversible and environmental sound manner without causing any new formation of PCDD/PCDF or HCB. The destruction and removal efficiency (DRE) was better than 99.9999% at the highest PCB feeding rate.

  14. Reducing Structural Violence through Entrepreneurial Tourism: Case Study in Hambantota District, Sri Lanka

    Shammika DLAH

    2014-01-01

    Full Text Available Tourism is increasingly recognized as an effective means of achieving peace in world. In this paper tourism’s contribution for peace will be discussed in a broader sense with identification of structural violence as the main cause of Sri Lankan conflict. Structural violence is the process of deprivation of needs. It is characterized politically as repression, and economically by exploitation. The methodology used in this paper to identify ‘how entrepreneurial tourism can contribute to alleviate structural violence’ was basically qualitative. The methodology was based on the grounded theory which portrays the world as being complex and organized by both overt and hidden power structures. It was revealed during the process of data collection that the structural violence was functioning by means of polarization of the social structures such as caste, ethnicity, economic status, nobility, educational status into different strata together with grouping of people into the consequential ends leading to social uneasiness. People engaged in entrepreneurial activities are entrapped in a viscous system of unfair resource allocation and production exploitation operating through intermediaries. The paper suggests that it is necessary to seek remedies to increase the capacity of entrepreneurs to overcome the destructive force of the structural violence.

    Objective To investigate the effect of 3-year phased bans of the pesticides dimethoate and fenthion in 2008–2010, and paraquat in 2009–2011, on suicide mortality in Sri Lanka. Methods Age-standardised overall, sex-specific, and method-specific suicide rates were calculated using Sri Lankan police data (1989–2015). Using negative binomial regression models, we estimated the change in the rate and number of suicide deaths in post-ban years (2011–15) compared to those expected based on pre-ban trends (2001–10). Findings Overall suicide mortality dropped by 21% between 2011 and 2015, from 18.3 to 14.3 per 100,000. The decline in pesticide suicides during this same period was larger than for overall suicides: from 8.5 to 4.2 per 100,000, a 50% reduction. This was accompanied by a smaller concurrent rise in non-pesticide suicide mortality with a 2% increase (9.9 to 10.1 per 100,000). In 2015, the ratio between the observed and expected pesticide suicide rates was 0.49 (95% confidence interval [CI] 0.40, 0.62), corresponding to an estimated 937 (95% CI 574, 1389) fewer pesticide suicides than expected from pre-ban suicide rates. Findings were similar in sensitivity analyses using 2008 or 2012 as commencement of the post intervention period. Conclusion Bans of paraquat, dimethoate and fenthion in Sri Lanka were associated with a reduction in pesticide suicide mortality and in overall suicide mortality despite a small rise in other methods. This study provides further evidence for the effectiveness of pesticide regulation in limiting the availability of highly hazardous pesticides and thereby reducing the number of global suicides.

  16. Sri Lanka drops leading condom.

    Science.gov (United States)

    1984-01-01

    Sri Lanka's Family Planning Association has stopped selling its Preethi Regular condom, the backbone of its social marketing program for nearly a decade. Last year nearly 7 times as many Preethi condoms were sold as all other brands combined. The decision was reported to be caused by budget constraints following the International Planned Parenthood Federation's (IPPF) new policy of limiting the number of Preethi Regular condoms supplied to Sri Lanka. IPPF's Asian Regional Officer reported that the Preethi condom is a costly product, and that as many as needed of a US Agency for International Development (USAID) supplied product will be sent to Sri Lanka. The Contraceptive Retail Sales (CRS) program has devised a new sales strategy, based partly on the introduction of a high-priced condom to fill the gap left by the discontinuation of the Preethi Regular. The new Preethi Gold condom is expected to help the project become more financially self-reliant while taing advantage of Preethi's marketplace popularity. Preethi Gold is manufactured by the Malaysia Rubber Company and costs the project US $4.85/gross. It is sold for US $.14 for 3, about 3 times the price of a Preethi Regular. The project is also pushing the Panther condom, donated to IPPF by USAID. 2 Panther condoms sell for about 3.6U, about the cost of Preethi Regulars. The project also sells Moonbeam, Rough Rider, and Stimula condoms, the latter 2 at full commercial prices. A smooth transfer of demand from Preethi to Panther had been desired, but by the end of 1983 some retailers were hesitating to make the product switch because some Preethi Regulars were still available. Total condom sales in 1983 were down by nearly 590,000 from the approximately 6,860,000 sold in 1982. Total condom sales for the 1st quarter of 1984 were slightly over 1,218,000 pieces, compared to about 1,547,000 for the same quarter in 1983, a decline of 21%. The Family Planning Association is gearing up to reverse the downward trend

    Full Text Available Chronic folliculitis (CF is a chronic infection of hair follicles leading to atrophy and loss of the affected hairs. This study was done on 51 patients with CF presenting at the Dermatology Clinic at General Hospital Matara, Sri Lanka, to identify specific clinical features and aetiological factors, and to study histopathology. Pus cultures were done on 25 cases. Biopsies were done on 6 patients. CF was commoner in males (59%; 76% were under 34 years, and 39% had occupational exposure to possible irritants. Thirty five precent admitted of scrubbing legs with rough objects. Ichthyosis vulgaris was evident in 47%. All pus cultures revealed Staphylococcus aureus. Clinical features and histopathological features were similar to those described by Harman (1968. Rough scrubbing, ichthyosis and occupational exposure to irritants may be aetiologically relevant.

The present study investigates risks associated with environmental, animal and occupational exposure. Data was obtained from structured.......213-93.582). Leptospirosis in paddy workers was associated with environmental factors linked to contamination and wetness in paddy fields. Interestingly abandoned paddy fields were found to have a protective effect against transmission to paddy workers (OR=0.421, 95% CI 0.237-0.748). Keeping animals on these dryer fields...... may act as a boundary for contamination of paddy fields with infectious animal urine. This finding could be considered in public health interventions targeting leptospirosis among paddy workers....

    Full Text Available Context: To date, a clear understanding of dengue disease pathogenesis remains elusive. Some infected individuals display no symptoms while others develop severe life-threatening forms of the disease. It is widely believed that host genetic factors influence dengue severity. Aims: This study evaluates the relationship between certain polymorphisms and dengue severity in Sri Lankan patients. Settings and Design: Polymorphism studies are carried out on genes for; transporter associated with antigen presentation (TAP, promoter of tumor necrosis factor-α (TNF-α, and promoter of interleukin-10 (IL-10. In other populations, TAP1 (333, TAP2 (379, TNF-α (−308, and IL-10 (−1082, −819, −592 have been associated with dengue and a number of different diseases. Data have not been collected previously for these polymorphisms for dengue patients in Sri Lanka. Materials and Methods: The polymorphisms were typed by amplification refractory mutation system polymerase chain reaction in 107 dengue hemorrhagic fever (DHF patients together with 62 healthy controls. Statistical Analysis Used: Pearson′s Chi-square contingency table analysis with Yates′ correction. Results: Neither the TAP nor the IL-10 polymorphisms considered individually can define dengue disease outcome with regard to severity. However, the genotype combination, IL-10 (−592/−819/−1082 CCA/ATA was significantly associated with development of severe dengue in these patients, suggesting a risk factor to developing DHF. Also, identified is the genotype combination IL-10 (−592/−819/−1082 ATA/ATG which suggested a possibility for protection from DHF. The TNF-α (−308 GG genotype was also significantly associated with severe dengue, suggesting a significant risk factor. Conclusions: The results reported here are specific to the Sri Lankan population. Comparisons with previous reports imply that data may vary from population to population.

    Even though health workers have treated all registered cases of leprosy in Sri Lanka with multiple drug therapy since 1982, it continues to be transmitted. The government has launched a social marketing and social mobilization campaign to reduce the incidence of leprosy. It has expanded the network of leprosy services. A national advertising program included mass media ads, posters, stickers on buses, and radio and television serials to create awareness of the early signs of leprosy and to reduce fear to leprosy. Health workers distributed leaflets and booklets to the general public and to new patients. The Anti-Leprosy Campaign of Sri Lanka organized 1-week health education programs for administrative officer, village leaders, religious leaders, teachers, and voluntary workers. Skin camps were set up to detect leprosy cases and to treat minor skin disorders. Teachers received flip charts on leprosy to help them teach colleagues and children about leprosy. All primary level staff, medical officers in hospital staff, and estate medical and paramedical staff have undergone special training on diagnosing leprosy and on reducing their fear of it. Almost every district has at least 1 leprosy control specialist. 2 leprosy control specialists work in those districts where leprosy is endemic Each district has a trained medical laboratory technician, who stains and interprets leprosy smears. In 1992, school, contact, and mass surveys have found 31, 149, and 225 new cases, respectively. Active case findings methods found 16.5% of new cases. 50% of new cases are self- reported, compared to less than 10% in 1989, suggesting increased awareness of early signs of leprosy and a reduced fear of it. 25 more clinics opened in 1991 to meet the demand for leprosy services.

    The devastating impact of the tsunami of 26 December 2004 on the shores of the Indian Ocean recalled the importance of knowledge and the taking into account of coastal hazards. Sri Lanka was one of the countries most affected by this tsunami (e.g. 30 000 dead, 1 million people homeless and 70% of the fishing fleet destroyed). Following this tsunami, as part of the French post-tsunami aid, a project to establish a Geographical Information System (GIS) on coastal hazards and risks was funded. This project aims to define, at a pilot site, a methodology for multiple coastal hazards assessment that might be useful for the post-tsunami reconstruction and for development planning. This methodology could be applied to the whole coastline of Sri Lanka. The multi-hazard approach deals with very different coastal processes in terms of dynamics as well as in terms of return period. The first elements of this study are presented here. We used a set of tools integrating a GIS, numerical simulations and risk scenario modelling. While this action occurred in response to the crisis caused by the tsunami, it was decided to integrate other coastal hazards into the study. Although less dramatic than the tsunami these remain responsible for loss of life and damage. Furthermore, the establishment of such a system could not ignore the longer-term effects of climate change on coastal hazards in Sri Lanka. This GIS integrates the physical and demographic data available in Sri Lanka that is useful for assessing the coastal hazards and risks. In addition, these data have been used in numerical modelling of the waves generated during periods of monsoon as well as for the December 2004 tsunami. Risk scenarios have also been assessed for test areas and validated by field data acquired during the project. The results obtained from the models can be further integrated into the GIS and contribute to its enrichment and to help in better assessment and mitigation of these risks. The coastal

    Full Text Available Abstract Background To identify non-cognitive and socio-demographic characteristics determining academic success of Sri Lankan medical undergraduates. Methods A retrospective study among 90 recently graduated students of the Faculty of Medical Sciences, University of Sri Jayewardenepura, Sri Lanka. Students were stratified into two equal groups; ‘High-achievers’ (honours degree at the final MBBS examination and ‘Low-achievers’ (repeated one or more subjects at the same examination. A revised version of the Non-cognitive Questionnaire (NQ with additional socio-demographic data was the study instrument. Academic performance indicator was performance at the final MBBS examinations. A binary logistic regression analysis was performed using the dichotomous variable ‘Honours degree at final MBBS’ as the dependant factor. Results Males were 56.7%. Mean age ± SD was 26.4 ± 0.9 years. ‘High-achievers’ were significantly younger than ‘Low-achievers’. Significant proportion of ‘High-achievers’ were from the Western province and selected to university from Colombo district. A significant majority of ‘High-achievers’ entered medical school from their first attempt at GCE A/L examination and obtained ‘Distinctions’ at the GCE A/L English subject. ‘High-achievers’ demonstrated a significantly higher mean score for the following domains of NQ; Positive self-concept and confidence, realistic self-appraisal, leadership, preference of long range goals and academic familiarity. The binary logistic regression indicates that age, being selected to university from Colombo district, residency in Western province, entering university from GCE A/L first attempt, obtaining a ‘Distinction’ for GCE A/L English subject, higher number of patient-oriented case discussions, positive self-concept and confidence, leadership qualities, preference of long range goals and academic familiarity all significantly increased the odds of

    Full Text Available Several shell middens of coastal Sri Lanka indicate human occupation in the mid-Holocene and are recognized as being of prime importance in the archaeological narrative of the island. A salvage archaeology operation conducted at the Mini-athiliya shell midden in the Southern Province of Sri Lanka, yielded ancient human remains associated with stone implements and culturally modified faunal remains. The main objective of this rescue operation was to mitigate the destruction to this archaeological site. We report the excavation strategy and dating of this mid-Holocene shell midden, while focusing on the discovery and extraction of a complete human burial that had not been disturbed by the shell mining activity at the site. This excavation is intended to serve as a precursor to systematic investigation of the coastal shell middens of southern Sri Lanka.

    Full Text Available BACKGROUND: Sri Lankan rural doctors based in isolated peripheral hospitals routinely resuscitate critically ill patients but have difficulty accessing training. We tested a train-the-trainer model that could be utilised in isolated rural hospitals. METHODS: Eight selected rural hospital non-specialist doctors attended a 2-day instructor course. These "trained trainers" educated their colleagues in advanced cardiac life support at peripheral hospital workshops and we tested their students in resuscitation knowledge and skills pre and post training, and at 6- and 12-weeks. Knowledge was assessed through 30 multiple choice questions (MCQ, and resuscitation skills were assessed by performance in a video recorded simulated scenario of a cardiac arrest using a Resuci Anne Skill Trainer mannequin. RESULTS/DISCUSSION/CONCLUSION: Fifty seven doctors were trained. Pre and post training assessment was possible in 51 participants, and 6-week and 12-week follow up was possible for 43, and 38 participants respectively. Mean MCQ scores significantly improved over time (p<0.001, and a significant improvement was noted in "average ventilation volume", "compression count", and "compressions with no error", "adequate depth", "average depth", and "compression rate" (p<0.01. The proportion of participants with compression depth ≥40mm increased post intervention (p<0.05 and at 12-week follow up (p<0.05, and proportion of ventilation volumes between 400-1000mls increased post intervention (p<0.001. A significant increase in the proportion of participants who "checked for responsiveness", "opened the airway", "performed a breathing check", who used the "correct compression ratio", and who used an "appropriate facemask technique" was also noted (p<0.001. A train-the-trainer model of resuscitation education was effective in improving resuscitation knowledge and skills in Sri Lankan rural peripheral hospital doctors. Improvement was sustained to 12 weeks for most

    Naja naja (Indian cobra) from Sri Lanka and India is the WHO Category 1 medically important snakes in both countries. Some antivenom produced against Indian N. naja (NNi) were less effective against Sri Lankan N. naja (NNsl). Proteomes of NNi and NNsl venoms were studied by RP-HPLC, SDS-PAGE and LC/MS/MS. Six protein families were identified in both venoms with the most abundant were the 3 finger toxins (3FTs) where cytotoxins (CTX) subtype predominated, followed by phospholipase A2, cysteine-rich venom protein, snake venom metalloproteases, venom growth factors, and protease inhibitors. Qualitative and quantitative differences in the venomics profiles were observed. Some proteins were isolated from either NNi or NNsl venom. Postsynaptic neurotoxins (NTX) were identified for the first time in NNsl venom. Thus, there are geographic intra-specific variations of venom composition of the two N. naja. The relative abundance of CTX and NTX explained well the clinical manifestations of these venoms. Antivenomics study of an Indian antivenom (Vins) showed the antibodies effectively bound all venom toxins from both snakes but more avidly to the Indian venom proteins. The lower antibody affinity towards the 'heterologous' venom was the likely cause of poor efficacy of the Indian antivenom used to treat NNsl envenoming.

    Leishmania donovani is the known causative agent of both cutaneous (CL) and visceral leishmaniasis in Sri Lanka. CL is considered to be under-reported partly due to relatively poor sensitivity and specificity of microscopic diagnosis. We compared robustness of three previously described polymerase chain reaction (PCR) based methods to detect Leishmania DNA in 38 punch biopsy samples from patients presented with suspected lesions in 2010. Both, Leishmania genus-specific JW11/JW12 KDNA and LITSR/L5.8S internal transcribed spacer (ITS)1 PCR assays detected 92% (35/38) of the samples whereas a KDNA assay specific forL. donovani (LdF/LdR) detected only 71% (27/38) of samples. All positive samples showed a L. donovani banding pattern upon HaeIII ITS1 PCR-restriction fragment length polymorphism analysis. PCR assay specificity was evaluated in samples containing Mycobacterium tuberculosis, Mycobacterium leprae, and human DNA, and there was no cross-amplification in JW11/JW12 and LITSR/L5.8S PCR assays. The LdF/LdR PCR assay did not amplify M. leprae or human DNA although 500 bp and 700 bp bands were observed in M. tuberculosis samples. In conclusion, it was successfully shown in this study that it is possible to diagnose Sri Lankan CL with high accuracy, to genus and species identification, using Leishmania DNA PCR assays.

    In order to investigate the relationship between sex dysplasia and sex-determining region Y (SRY) gene, 8 patients with sexual abnormality were analyzed by cytogenetic and molecular genetic methods. Fluorescence in situ hybridization (FISH) using PY3.4, X alpha satellite, and SRY probes was performed in each case to analyze the sex chromosome translocation and gene translocation. SRY gene was amplified by polymerase chain reaction (PCR) and its mutation was detected by direct sequencing. The results showed that among 8 patients, 5 were positive for SRY and the remaining negative for SRY. In the patients positive for SRY genes, 3 presented testes and the left 2streak ovaries. In the patients negative for SRY, only one case presented testes, while 2 ovaries.Direct sequencing demonstrated that all SRY genes were normal in the patients positive for SRY genes. FISH technique demonstrated that SRY genes translocated from Ypter to Xpter in 2 46,XX phenotypic males positive for SRY genes. It was concluded that SRY gene is strongly involved in.male sex determination, while a sequence of other genes may be taken into account in sexual development.

    Samples of 226 new improved and 21 indigenous rice (Oryza sativa L.) varieties were collected from the rice fields in three climatic zones of Sri Lanka and concentrations of 18 trace elements (Li, B, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba, Pb and Bi) were measured giving particular emphasis on Se, Cd and As using ICP-MS. The two way multivariate analysis of variance (MANOVA) method was employed to identify the differences in composition among rice from different climatic zones. The mean values obtained for both white and red rice were Se (36; 25 µg/kg), As (42; 45 µg/kg) and Cd (70; 123 µg/kg) on dry weight basis. However mean content of Se, As and Cd of native rice varieties were 69, 74 and 33 µg/kg, respectively. Statistical interpretations showed that in the majority of cases, there was a significant difference in Cd content among climatic zones whereas Se and Pb show differences between white and red rice varieties. Arsenic did not indicate any significant difference either between rice types or among climatic regions. Notably Se and As contents in indigenous rice were higher than that of improved rice types. To assess the safety of dietary of intake, daily intake of Se, Cd and As by rice were calculated. Non-gender specific Estimated Daily Intake (EDI) of Se, Cd and As consuming improved rice are 9.31, 24.1 and 12.2 µg day(-1), respectively. Since over 50 % of daily meals of people contain rice or rice based products, Se intake is expected to be deficient among the Sri Lankan population.

    Full Text Available Asian tectonism and exhumation are critical components to develop modern icehouse climate. In this study, stratigraphic sections of eight wells in the Mannar and Cauvery basins were considered. The author demonstrated that this local system records a wealth of information to understated regional and global paleoclimatic trends over the Cenozoic era. The lithostratigraphic framework has been generally characterized by deposition of carbonate-rich sediments since the Middle Cenozoic. Geological provenance of carbonate sediments had probably related to local sources from Sri Lankan and Indian land masses. The main controlling factor of carbonate burial is rather questionable. However, this carbonate burial has indicated the possible link to the Middle to Late Cenozoic global climatic transition. This major climatic shift was characterized by long-term reduction of atmospheric carbon dioxide concentration over the Cenozoic era. Consequently, this geological trend (carbonate burial has a straightforward teleconnection to the global cooling towards the glaciated earth followed by the development of polar ice sheets that persist today.

    Sri Lanka is one of the intermediate-endemic areas for hepatitis A virus (HAV), and concerns exist about the increasing HAV-susceptible population. In fact, Sri Lanka recorded a large hepatitis outbreak, possibly hepatitis A, around the end of the Sri Lankan war. It included more than 14,000 patients consisting of local residents, internally displaced personnel, and military personnel in the main combat zone. The outbreak had slowed down by October 2009; however, acute viral hepatitis continued to occur sequentially among military personnel. We obtained clinical information and serum samples from 222 patients with acute hepatitis who visited the Military Hospital Anuradhapura between January and September 2010. Samples were subjected to laboratory testing including HAV-immunoglobulin M and genotyping. Most patients (98.2%) were confirmed as having hepatitis A belonging to two subgenotypes: IA and IIIA. We did not observe any differences in clinical or biochemical features among patients with subgenotypes IA and IIIA except for pale stools and upper abdominal discomfort. During the investigation period, we observed a serial outbreak caused by identical HAV strains with an interval in line with that of typical HAV incubation periods. Most patients in the first outbreak were found in the training center, and patients in the second outbreak were found in multiple places where soldiers were assigned after the training center. These findings indicate that a strain of HAV diffused from one place to another along with movement of infected persons among the HAV-susceptible population. HAV vaccination for high-risk groups, such as young soldiers, is necessary. © The American Society of Tropical Medicine and Hygiene.

    Full Text Available Objective: To evaluate a range of anti-diabetic related properties and some consumer preferred physicochemical properties of selected Sri Lankan traditional rice varieties. Methods: Sudu Heeneti, Goda Heeneti, Masuran and Dik Wee varieties were used in this study. Anti-diabetic related properties of bran extracts of selected varieties were studied for methylglyoxal mediated protein glycation inhibition, acetyl and butyryl-cholinesterase inhibition in vitro and anti-hyperglycemic activity in vivo. Further, selected varieties were studied for starch hydrolysis rate in vitro. Physicochemical properties including grain color, size, shape, crude protein, crude fat, ash, dietary fiber and total carbohydrate contents were studied. Results: Brans of selected varieties had significant (P < 0.05 and dose dependent methylglyoxal mediated protein glycation inhibition [IC50: (174.77 ± 6.65 to (342.87 ± 0.43 µg/mL] and acetyl [(IC50: (37.00 ± 0.68 to (291.00 ± 3.54 µg/mL] and butyryl-cholinesterase [IC50: (18.50 ± 0.60 to (96.60 ± 0.56 µg/mL] inhibitory activities. Further, Sudu Heeneti, Masuran and Dik Wee had low starch digestion rate (52.40 ± 1.44 to 53.76 ± 1.19 indicating that these varieties may be low glycemic index rices. Brans of Masuran tested in rat model showed anti-hyperglycemic activity. Physicochemical properties studied showed that selected varieties were red in color and grain size and shape were mostly medium and bold respectively. Moisture, crude protein, crude fat, ash and total carbohydrate contents varied significantly (P < 0.05 among the varieties. Conclusions: It is concluded that selected varieties could be promoted as physicochemically sound rices with a range of anti-diabetic related properties in the management of diabetes and its complications.

    Dimensions of social capital relevant to health in pregnancy are sparsely described in the literature. This study explores dimensions of social capital and the mechanisms in which they could affect the health of rural Sri Lankan pregnant women. An exploratory qualitative study of solicited diaries written by pregnant women on their social relationships, diary interviews and in-depth interviews with key informants was conducted. A framework approach for qualitative data analysis was used. Pregnant women (41), from eight different communities completed diaries and 38 post-diary interviews. Sixteen key informant interviews were conducted with public health midwives and senior community dwellers. We identified ten cognitive and five structural constructs of social capital relevant to health in pregnancy. Domestic and neighborhood cohesion were the most commonly expressed constructs. Social support was limited to support from close family, friends and public health midwives. A high density of structural social capital was observed in the micro-communities. Membership in local community groups was not common. Four different pathways by which social capital could influence health in pregnancy were identified. These include micro-level cognitive social capital by promoting mental wellbeing; micro-level structural social capital by reducing minor ailments in pregnancy; micro-level social support mechanisms promoting physical and mental wellbeing through psychosocial resources and health systems at each level providing focused maternal care. Current tools available may not contain the relevant constructs to capture the unique dimensions of social capital in pregnancy. Social capital can influence health during pregnancy, mainly through improved psychosocial resources generated by social cohesion in micro-communities and by the embedded neighborhood public health services.

    Full Text Available Fishes are the primary source of animal protein more than 70% Sri Lankans population depends on fish product for fulfill their daily protein requirement. In 2013, per capita fish consumption was 40.4 g/day. Fish consumption varies among consumers and it determined by many factors, including sociodemographics and fish availability in the local market. To determine the availability and frequency of fish occurrence in local and urban markets, as well as other factors associated with the choice of fish, a market survey was conducted in the Batticaloa district in the Eastern Province from December 2013 to October 2014, covering the 12 urban and rural markets. Fish species, frequency of occurrence (in percentage, and overall fish availability were recorded by direct observation. Consumer preferences regarding fish species were collected via customer interviews (n=150. Carangidae (85% and Sphyranidea (80.5% were frequent among rockfish species in both dry and rainy seasons in urban markets. Among shore species Clupeidae (95.5% and Leionathidae (83.5% were found in both urban and rural markets in all seasons. Rockfish was the most preferred (75% among middle class consumers. In local markets, most consumers (78% preferred shore fish because it was cheapness, and availability throughout the year. However, urban consumers did not share this preference; only 20–25% of urban consumers preferred shore fish. It was noted that religious and cultural factors influenced fish consumption in rural and local markets. Further, the markets witnessed reduced economic activity when they were closed during certain months (i.e., June to August due to lower number of fish consumers.

  19. Assessment of Variable Planting Date as an Agricultural Adaptation to Climate Variability in Sri Lanka

    Agriculture accounts for approximately 70% of global freshwater withdrawals. Changes in precipitation patterns due to climate change as well as increasing demands for water necessitate an increased understanding of the water-­food intersection, notably at a local scale to inform farmer adaptations to improve water productivity, i.e., to get more food with less water. Local assessments of water-food security are particularly important for nations with self-sufficiency policies, which prioritize in-country production of certain resources. An ideal case study is the small island nation of Sri Lanka, which has a self-sufficiency policy for its staple food of rice. Because rice is a water-intensive crop, assessment of irrigation water requirements (IWRs) and the associated changes over time is especially important. Previous studies on IWRs of rice in Sri Lanka have failed to consider the Yala (dry) season, when water is scarcest.The goal of this study is to characterize the role that a human decision, setting the planting date, can play in buffering declines in rice yield against changes in precipitation patterns. Using four meteorological stations in the main rice-growing zones in Sri Lanka, we explore (1) general changes in IWRs over time during the Yala season and (2) the impact of the rice planting date. We use both historical data from meteorological stations as well as future projections from regional climate models. Our results indicate that gains can be achieved using a variable planting date relative to a fixed date, in accordance with a similar conclusion for the Maha (wet) season. This local scale assessment of Sri Lanka IWRs will contribute to the growing global literature on the impacts of water scarcity on agriculture and the role that one adaptation measure can play in mitigating deleterious impacts.

  20. Sri Lanka: sterilization bonus announced in Sri Lanka; new CBD experiments in Sri Lanka; orchids and family planning.

    The government of Sri Lanka will give a minimum bonus of SRs 100 ($US6.00) to anyone voluntarily being sterilized. Women will be given 7 days leave and men 3. Many public and private corporations pay sterilization bonuses; the new bonus was set to compete with generous maternity benefits. The average daily wage is about SRs 120. Currently the demand for sterilization is greater than the health services' ability to meet it. Depo-provera is becoming increasingly popular in Sri Lanka, especially among the Muslim communities. The Family Planning Association of Sri Lanka is to test new forms of social marketing of contraceptives to provide wider coverage through community-based distribution. One system will use the route of a commercial firm, Reckitt and Coleman Ltd., and another system will use a network of provincial organizers, commission agents, and local retailers. To create an awareness in young people of their responsibility toward society the Family Planning Association organized an orchid cultivation and family planning propaganda project. 40 young boys are being taught orchid culture and the benefits of family planning. Orchids can be grown in the back yard without any capital investment. There is a steady market for the orchids, and the training program lasts 6 months for each cohort of boys.

    Emotional intelligence (EI) has been linked with academic and professional success. Such data are scarce in Sri Lanka. This study was conducted to describe the pattern of EI, to determine its predictors and to determine the effect of EI on academic performance at the final MBBS examination, in medical undergraduates of a Sri Lankan university. This is a cross-sectional study in a selected university, involving those who did final MBBS examination in 2016. Consecutive sampling was done. EI was assessed with self-administered Genos Emotional Intelligence Full Version (7 domains; 70 questions equally weighted; total score 350). Socio-demographic data were obtained using a self-administered questionnaire. Academic performance was assessed with final MBBS results in the first attempt. Of 148 eligible students 130 responded (response rate-88%); 61.5% were females; mean age was 26.3 ± 1 years. Mean total EI score was 241.5 (females-245.5, males-235.1; p = 0.045).Among different domains, mean score was highest for Emotional Self-Awareness (36.8/50) and lowest for Emotional Expression (32.6/50). Multiple linear regression analysis indicated that having good family support (p = 0.002), socializing well in university (p = 0.024) and being satisfied with facilities available for learning (p = 0.002), were independent predictors of EI. At the final MBBS examination 51.6% obtained classes, 31.5% passed the examination without classes and 16.9% got repeated. Females had better academic performance than males (p = 0.009). Mean EI of second-class upper division, second-class lower division, pass and repeat groups were 249.4, 246.6, 240.2 and 226.9, respectively (with one-way ANOVA p = 0.015). After adjusting for gender, ordinal regression analysis indicated that, total EI score was an independent predictor of final MBBS results [β-0.018 (95% CI 0.005-0.031); p = 0.006]. In the study population, both EI and academic performance were higher among

    This paper evaluated the post-installation impacts of Light Up the World's (LUTW) solid state lighting (SSL) project in 5 off-grid farming villages in Sri Lanka, where more than half the population does not have access to electricity. The LUTW Foundation is a humanitarian organization founded in 1997 to bring affordable, safe, healthy, reliable, and environmentally sound home lighting to developing countries. It brings SSL technologies to improve the quality of life for people living in villages with little realistic prospect for affordable electrification. In July 2002, LUTW provided SSL to the villages in Sri Lanka and has since installed lighting in nearly 400 homes located off-grid. The SSL systems used in the homes in the Sri Lankan projects consists of two 1-watt white light emitting diodes (WLED) lamps, one 12 volt 7 amp-hour sealed lead-acid battery and the required wiring and switches. Batteries are charged at village charging stations equipped with a 75 watt solar panel powering a car battery which recharges 12 small homeowner batteries. Each lamp costs about $20 USD. This report presents the results of a social and economic survey of the installations. The villagers were interviewed in order to evaluate the technical, social and economic impacts of LUTW's products on off-grid areas. The objective was to determine where improvements could be made to LUTW's capacity to deliver products with meaningful development impacts. The most quantitative benefit identified by the survey was a savings in kerosene fuel and money. In general, the LED light replaced 1 kerosene lantern except for high income groups who reduced their kerosene lamp use even more. Qualitatively, the LED provided other advantages over kerosene lighting, such as better quality of light; increased safety; increased academic performance for children; and, improved crop yields when used to ward off elephant ravage. The survey showed that not much importance was place on a more

    SRY (sex-determining region Y chromosome) is considered as a strong candidate for the TDF (testis determining factor) and has been cloned following another candidate ZFY (zinc finger protein gone). In this study,eight cases of sex reversal, including four 46, XX males and four 46, XY females were examined for the presence of SRY sequence and a Y-repeated DNA locus. Our data indicated that the genomie DNA of the four classical 46,XX males had the SRY sequences. On the other hand, both SRY sequences and Y-repeated DNA sequences were present in aii four 46, XY females.These results suggest that SRY sequences were responsible for the sex reversal of 46, XX males whereas there may be other genetic mechanisms for the sex reversal of 46, XY females without the lack of SRY sequences.

    Full Text Available To comprehensively review the issues of smokeless tobacco use in Sri Lanka . This review paper is based on a variety of sources including Medline, WHO documents, Ministry of Health and Nutrition, Colombo and from other sources. Results: The prevalence of smokeless tobacco (SLT use in Sri Lanka has been reported high, especially among rural and disadvantaged groups. Different smokeless tobacco products were not only widely available but also very affordable. An increasing popularity of SLT use among the youth and adolescents is a cause for concern in Sri Lanka. There were evidences of diverse benign, premalignant, and malignant oral diseases due to smokeless tobacco use in the country. The level of awareness about health risks related to the consumption of smokeless tobacco products was low, particularly among the people with low socio-economic status. In Sri Lanka various forms of smokeless tobacco products, some of them imported, are used. At the national level, 15.8% used smokeless tobacco products and its use is three-fold higher among men compared to women. Betel quid is by far the traditional form in which tobacco is a general component. Other manufactured tobacco products include pan parag/pan masala, Mawa, Red tooth powder, Khaini, tobacco powder, and Zarda. Some 8.6% of the youth are current users of smokeless tobacco. There are studies demonstrating the harmful effects of smokeless tobacco use, especially on the oral mucosa, however, the level of awareness of this aspect is low. The highest mean expenditure on betel quid alone in rural areas for those earning Rs. 5,000/month was Rs. 952. The core issue is the easy availability of these products. To combat the smokeless tobacco problem, public health programs need to be intensified and targeted to vulnerable younger age groups. Another vital approach should be to levy higher taxation.

  8. Forecasts of Agricultural Drought in Sri Lanka

    2015-12-01

    As the most frequent natural disaster in Sri Lanka, drought greatly affects crop production and livelihoods. Over half of all agricultural crop damage in Sri Lanka is currently due to drought; the frequency and severity of drought in the country is only expected to increase with the changing climate. Previous work indicates that the Palmer Drought Severity Index (PDSI) and Standardized Precipitation Index (SPI) are capable of capturing agricultural drought patterns (between 1881-2010) in the island nation. In this work, PDSI and SPI from 13 long-term meteorological stations will be projected into the future using a combination of artificial neural network and autoregressive integrated moving average models. The impacts of large-scale atmospheric circulation patterns (such as the Niño 3.4 index, a measure of sea surface temperature) and lead times on projection accuracy will also be explored. Model projections will be compared to weather data since 2010 to determine if the 2014 drought could have been forecasted using these methods. Since agricultural systems are strongly influenced by both natural and human systems, it is important to frame these physical findings within a social context. This work is part of an interdisciplinary project that assesses the perceptions of and adaptations to drought by rice farmers in Sri Lanka; disciplines represented in the group include hydrology, social psychology, ethnography, policy, and behavioral economics. Insights from the diverse research perspectives within the group will be drawn upon to highlight the social implications of the physical results.

    The World Health Organization-recommended patient care indicators in Government Hospitals were assessed in 422 patients attending the Outpatient Department in selected hospitals of the Galle district in Southern Province. The average dispensing time (ADT), percentage of drugs actually dispensed (PDAD), percentage of drugs adequately labeled (PDAL) and patient's knowledge on correct dosage (PKCD) were compared in these selected teaching hospitals (TH), general hospitals (GHs) and district hospitals (DHs) in Galle. ADT in DH (1.16 min) and GH (1.07 min) were high when compared with ADT in TH (0.81 min). PDAD was 100% in DH, 97.79% in GH and lowest in TH (94.64%). PDAL was highest (22.66%) in TH, 17.57% in GH and lowest in DH (1.57%). PKCD was 100% in GH and lowest in DH (0%) and only 50% in TH in Galle district. We noted that there was a significant difference in ADT in all three categories (P PKCD was 0% due to negligence in dispensing practices. We also noted a 100% PKCD only in GH due to the practice of a well-prepared correct labeling system in GH. We noticed that these patients were provided drugs with inadequate labeling and that patients had only a poor knowledge about the drug administration schedule. We conclude that there was a low dispenser-patient ratio in all three hospitals and that there was a need for an implementation plan for proper dispensing techniques by introducing a well-prepared drug labeling system in a printed format.

    Background Lower socioeconomic position (SEP) is associated with an increased risk of suicidal behaviour in high-income countries, but this association is unclear in low-income and middle-income countries. Methods We investigated the association of SEP with attempted suicide in a cross-sectional survey of 165 233 Sri Lankans. SEP data were collected at the household (assets, social standing (highest occupation of a household member), foreign employment and young (≤40 years) female-headed households) and individual level (education and occupation). Respondent-reported data on suicide attempts in the past year were recorded. Random-effects logistic regression models, accounting for clustering, were used to investigate the association of SEP with attempted suicide. Results Households reported 398 attempted suicides in the preceding year (239 per 100 000). Fewer assets (OR 3.2, 95% CI 2.4 to 4.4) and having a daily wage labourer (ie, insecure/low-income job; OR 2.3, 95% CI 1.6 to 3.2) as the highest occupation increased the risk of an attempted suicide within households. At an individual level, daily wage labourers were at an increased risk of attempted suicide compared with farmers. The strongest associations were with low levels of education (OR 4.6, 95% CI 2.5 to 8.4), with a stronger association in men than women. Conclusions We found that indicators of lower SEP are associated with increased risk of attempted suicide in rural Sri Lanka. Longitudinal studies with objective measures of suicide attempts are needed to confirm this association. Trial registration number NCT01146496; Pre-results. PMID:28336743

    2012-12-01

    Full Text Available Abstract Background Exclusive breastfeeding (EBF during the early months of life reduce infant morbidity and mortality. Current recommendation in Sri Lanka is to continue exclusive breastfeeding up to six months of age. Exclusive breastfeeding rates are generally assessed by the 24 recall method which overestimates the actual rates. The objective of this study was to determine actual exclusive breast feeding rates in a cohort of Sri Lankan children and to determine the reasons that lead to cessation of breastfeeding before six months of age. Methods From a cohort of 2215 babies born in Gampaha district, 500 were randomly selected and invited for the study. They were followed up at two (n = 404, four (n = 395 and six (n = 286 months. An interviewer administered questionnaire asked about feeding history and socio-demographic characteristics. Child health development record was used to assess the growth. Results Exclusive breastfeeding rates at two, four and six months were 98.0%, 75.4% and 71.3% respectively. The main reasons to stop exclusive breastfeeding between two to four months was concerns regarding weight gain and between four to six months were mothers starting to work. Majority of the babies that were not exclusively breastfed still continued to have breast milk. Mothers above 30 years had lower exclusive breastfeeding rates compared to younger mothers. Second born babies had higher rates than first borns. There was no significant association between maternal education and exclusive breastfeeding rates. Conclusions Exclusive breastfeeding rates were high among this cohort of children. A decrease in EBF was noted between two and four months. EBF up to six months does not cause growth failure. Mothers starting to work and concerns regarding adequacy of breast milk were the major reasons to cease EBF. The actual exclusive breastfeeding rates up to six months was 65.9%.

    The economic importance of Sri Lanka's coastal area has increased with rapid urbanization and the development of commercial harbours. The growth on this small island has resulted in unmistakable signs of environmental stress which manifests itself in the loss of natural forest cover, water pollution, degradation of rural lands and increased levels of air, water and solid waste pollution. The population is projected to reach 25 million by 2030. This will create an unprecedented demand for food, fibre energy, developable land and other natural resources. Pollution and competition for resources has already degraded about half of the shoreline which put sustainable economic development and environmental values at risk. It is estimated that 25,000 metric tonnes of waste is thrown into the oceanic waters each year. The pollutants include oil, garbage and chemicals from industries. In addition, 60 per cent of the sewage from the city of Colombo is dumped into the sea. Coral mining which supplies 90 per cent of the lime for the construction industry is leading to the destruction of reefs serving as natural barriers against tidal waves. In 1996, the government of Sri Lanka began a plan for coast erosion management in which community participation plays a vital role. A coastal conservation education project for school children is set to begin in the near future. 6 refs., 1 tab.

    Physical inactivity is the fourth leading risk factor for mortality worldwide and a leading risk factor for type 2 diabetes and cardiovascular disease. Medical undergraduates are a group of young adults expected to have a sound knowledge of the benefits of physical activity (PA) and have an active lifestyle. To quantifyPA levels among medical undergraduates of a Sri Lankan university and to determine the socio-demographic correlates of physical inactivity. Medical undergraduates in their third, fourth and fifth years of study were recruited for this quantitative, descriptive, cross-sectional study using a self-administered questionnaire. A total of 421 students were recruited. Overall 41% were physically inactive. Females (47%) were more inactive than males (34%). The total mean weekly metabolic equivalent (MET)-minutes was 1468.2±1873. Males (1676.2±1629) had a higher mean weekly MET minutes than females (1319±20102), p=0.05. 88% owned a portable internet device such as a smartphone or tablet. Students using health-related apps on their devices had significantly higherPA (p=0.01) and lower body mass index (BMI) (p=0.04), than those who did not. Binary logistic regression revealed physical inactivity to be significantly associated with gender (p=0.01), not using a health-promoting app on their portable device (p=0.01) and the year of study (p=0.03). Physical inactivity is a significant problem among medical undergraduates. The use of health applications was associated with a higher PA and lower BMI. The reasons for inactivity and the discrepancy in activity levels between males and females needs to be explored in greater detail. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Fish are considered as a unique source of protein and long chain polyunsaturated fatty acids (PUFA. In Sri Lankan population, fish consumption habits and attitudes are determined by the availability of fish and socio-demography of fish consumers. An extensive survey was carried out among fish consumers (N=1777 in stratified random manner. Among the total studied respondents, 73.3% of the respondents had eaten all type of fish while10% had only sea fishes, 19.5 % brackish water and rest 4.2% had eaten fresh water fishes. Furthermore, of total 19.1 % people had consumed fish daily while 80.9% people had consumed fish weekly or monthly. Results of the study concluded that 64 % studied respondents had fish at both lunch and dinner time while 25% had three times and rest11% consumed only at lunch. The choice of fish in market were determined by various factors such as taste (5.7%, smell (8.5%, appearance (51.5%, nutrition (2.1%, availability (12.7%, prize (37.3%, health (14%, quality (53%, shape (26.7% and considered all (24.2%. However, consumers were drawn their attention more than one factors in selecting fish from market. The results explained that quality of fish considered mostly in selection of fish with factors like prices and availability of fish. Among the studied respondents, the quantity of fish consumption varied with age such as 37.8% respondents which were belongs to the 36- 45 age group had 30-40g, while27.5 % were between ages of 46-55 had 41-50g daily and frequency of consumption was not independent of age (P<0.001. Of the total respondents, the trends of fish consumption for health purpose were varied and 37% respondents consume it to cure from heart diseases, while the 23% had fish to release pressure stroke (15%, eyesight (13% and during pregnancy (7%.

    Piper betle is an economically important plant cultivated in Sri Lanka. Although more than 12 cultivars of betel are reported in Sri Lanka, very few scientific investigations have been carried out on them. Studies on the chemical constituents indicated that safrole is the major constituent, followed by chavibitol acetate, in the essential oil of common betel leaves of Sri Lanka. Investigations on the bioactivities of P. betle revealed the presence of antimicrobial, insecticidal, antioxidant, antinociceptive, antidiabetic and gastroprotective activities. In addition, P. betle was found to be safe in terms of hepatotoxicity, renotoxicity, hematotoxicity, gross morphology, weights of organs, stress or aversive behaviors in rats. The above findings indicate the vast potential of P. betle yet to be harnessed for the benefit of mankind and the betel industry of Sri Lanka.

  14. Homegardens as a multi-functional land-use strategy in Sri Lanka with focus on carbon sequestration.

    Mattsson, Eskil; Ostwald, Madelene; Nissanka, S P; Marambe, Buddhi

    2013-11-01

    This paper explores the concept of homegardens and their potential functions as strategic elements in land-use planning, and adaptation and mitigation to climate change in Sri Lanka. The ancient and locally adapted agroforestry system of homegardens is presently estimated to occupy nearly 15 % of the land area in Sri Lanka and is described in the scientific literature to offer several ecosystem services to its users; such as climate regulation, protection against natural hazards, enhanced land productivity and biological diversity, increased crop diversity and food security for rural poor and hence reduced vulnerability to climate change. Our results, based on a limited sample size, indicate that the homegardens also store significant amount of carbon, with above ground biomass carbon stocks in dry zone homegardens (n = 8) ranging from 10 to 55 megagrams of carbon per hectare (Mg C ha(-1)) with a mean value of 35 Mg C ha(-1), whereas carbon stocks in wet zone homegardens (n = 4) range from 48 to 145 Mg C ha(-1) with a mean value of 87 Mg C ha(-1). This implies that homegardens may contain a significant fraction of the total above ground biomass carbon stock in the terrestrial system in Sri Lanka, and from our estimates its share has increased from almost one-sixth in 1992 to nearly one-fifth in 2010. In the light of current discussions on reducing emissions from deforestation and forest degradation (REDD+), the concept of homegardens in Sri Lanka provides interesting aspects to the debate and future research in terms of forest definitions, setting reference levels, and general sustainability.

    Full Text Available We report the results of the study that explored the factors characterizing the introduction of telemedicine to the rural areas of Sri Lanka. A model was developed from the analysis of the literature, expert review, and a field study conducted in three districts of Sri Lanka, which involved clinicians, hospital staff, and the general public from both rural and urban areas. Health ministry officials, medical directors, and consultants from urban areas were also consulted. Quantitative data from the questionnaires, and qualitative data from the interviews, were analyzed to investigate the impact on culture, technology, and infrastructure when adopting a telemedicine system in rural areas of Sri Lanka. The TeleMedicine in Sri Lanka (TMSL model is presented, which expresses the factors that hinder the acceptance of telemedicine in Sri Lanka. The key findings are that an understanding of the culture of Sri Lanka and additional computing skills are essential when implementing a telemedicine system in the rural areas of the country.

    Unprecedented incidence of dengue has been recorded in Sri Lanka in recent times. Source reduction and use of insecticides in space spraying/fogging and larviciding, are the primary means of controlling the vector mosquitoes Aedes aegypti and Ae. albopictus in the island nation. A study was carried out to understand insecticide cross-resistance spectra and mechanisms of insecticide resistance of both these vectors from six administrative districts, i.e. Kandy, Kurunegala, Puttalam, Gampaha, Ratnapura and Jaffna, of Sri Lanka. Efficacy of the recommended dosages of frequently used insecticides in space spraying and larviciding in dengue vector control programmes was also tested. Insecticide bioassay results revealed that, in general, both mosquito species were highly resistant to DDT but susceptible to propoxur and malathion except Jaffna Ae. aegypti population. Moderate resistance to malathion shown by Jaffna Ae. aegypti population correlated with esterase and malathion carboxylesterase activities of the population. High levels of acetylcholinesterase (AChE) insensitivity in the absence of malathion and propoxur resistance may be due to non-synaptic forms of AChE proteins. Moderate pyrethroid resistance in the absence of high monooxygenase levels indicated the possible involvement of 'kdr' type resistance mechanism in Sri Lankan dengue vectors. Results of the space spraying experiments revealed that 100% mortality at a 10 m distance and >50% mortality at a 50 m distance can be achieved with malathion, pesguard and deltacide even in a ground with dense vegetation. Pesguard and deltacide spraying gave 100% mortality up to 50 m distance in open area and areas with little vegetation. Both species gave >50% mortalities for deltacide at a distance of 75 m in a dense vegetation area. Larval bioassays conducted in the laboratory showed that a 1 ppm temephos solution can maintain a larval mortality rate of 100% for ten months, and the mortality rate declined to 0% in the

    SRY on the Y chromosome initiates male sex determination. We tested a phenotypic female with sex chromosome mosaicism, X/XYY, for SRY expression. SRY was determined by polymerase chain reaction (PCR) amplification in genomic DNA from a female patient with a sex chromosome mosaic complement, 45,X/47,XYY, followed by sequencing analyses. The patient yielded the PCR product with predicted size and homology to the consensus sequence of SRY. The demonstration of SRY provides evidence that the female phenotype in the presence of sex chromosome mosaicism, X/XYY, may result from alterations in another part of the sex-determining pathway or downstream from SRY.

    To identify areas of deficiencies and gaps in child protection services in Northern Sri Lanka. Also, to help in recommending strategies, programmes of interventions for addressing issues of child abuse and advice the legal system. A retrospective study was done to determine the socio-demographic details, type of abuse, clinical profile, relationship of the perpetrator and nature of abuse among children admitted to a tertiary care centre from 2009 through 2014, a period after cessation of a 60-y conflict. Data were obtained from hospital based records and records maintained at the district probation office. Seven hundred twenty cases were referred to the tertiary care centre with abuse. Majority of the children were from the Jaffna district, the northern city of the war affected area and mean age of the children affected was 14.5 ± 2.6 y. Females were affected more than the males and 352 children were seen following sexual abuse. The clinical examination showed penetrative injury in 15 %. The perpetrator was known in 70 % of the situations and the victim was coerced into a relationship for abuse. Attempted suicide was seen in significant numbers during the immediate post war period and school dropout and delinquent behaviour was seen in later years. The problem of child abuse is considerable in this region and there is an urgent need to strengthen the services offered to the victims. Urgent steps are needed to safeguard these children, especially in the war affected areas.

    2013-10-01

    Full Text Available The Chronic Kidney Disease (CKD, taking the lives of thousands in poor farming communities in Sri Lanka, is commonly seen as a problem peculiar to the island’s north central dry zone agricultural region. The prevailing bio-medical focus is on identifying one or more “environmental nephrotoxins.” While delineating important controversies on the etiology of the disease, this article seeks to broaden the discourse on the hitherto neglected political economy of CKD in Sri Lanka. In so doing, it seeks to bring together the bio-medical debate on the impact of widespread and unregulated use of agrochemicals on public health and kidney disease with broader global interdisciplinary perspectives on the industrialization of agriculture and the consolidation of food production by transnational agribusiness corporations. The article concludes pointing out environmentally sustainable and socially equitable development and organic agriculture as the long-term solutions to CKD in Sri Lanka and elsewhere.

    The Twin Research Registry (TRR) at SRI International is a community-based registry of twins established in 1995 by advertising in local media, mainly on radio stations and in newspapers. As of August 2012, there are 3,120 same- and opposite-sex twins enrolled; 86% are 18 years of age or older (mean age 44.9 years, SD 16.9 years) and 14% less than 18 years of age (mean age 8.9 years, SD 4.5); 67% are female, and 62% are self-reported monozygotic (MZ). More than 1,375 twins have participated in studies over the last 15 years in collaboration with the University of California Medical Center in San Francisco, the University of Texas MD Anderson Cancer Center, and the Stanford University School of Medicine. Each twin completes a registration form with basic demographic information either online at the TRR Web site or during a telephone interview. Contact is maintained with members by means of annual newsletters and birthday cards. The managers of the TRR protect the confidentiality of twin data with established policies; no information is given to other researchers without prior permission from the twins; and all methods and procedures are reviewed by an Institutional Review Board. Phenotypes studied thus far include those related to nicotine metabolism, mutagen sensitivity, pain response before and after administration of an opioid, and a variety of immunological responses to environmental exposures, including second-hand smoke and vaccination for seasonal influenza virus and Varicella zoster virus. Twins in the TRR have participated in studies of complex, clinically relevant phenotypes that would not be feasible to measure in larger samples.

    Freshwater snails (family Paludomidae, genus Paludomus) were collected from streams in Hedeniya and Peradeniya (the campus of Peradeniya University), Kandy district, Central Province, Sri Lanka, and found to harbor rediae and cercariae of a Paragonimus sp. These larvae were identified as Paragonimus westermani by using ITS2 DNA sequences. The infection rates of P. westermani in Paludomus sp. in Hedeniya and Peradeniya were 0.1% (one of 1014) and 0.2% (two of 1006), respectively. The snail has not been identified to species in the present study. This is the first report of the snail host of Paragonimus in Sri Lanka.

    HARRY STACK SULLIVAN'S argument that anxiety as a fundamental human experience is alleviated by the use of various procedures that he called "security operations" is used in this paper to examine the meaning of astrology in Sri Lanka. Astrology and the doctrine of karma provide the relevant framework in which various forms of misfortune are understood and handled. An examination of cases in Sri Lanka reveals that astrology and the doctrine of karma enable a person of that culture to create a number of structures which have a therapeutic effect.

    2005-01-01

    During the recent past the rainfall pattern in Sri Lanka has shown a noticeable change. This paper describes the effect of this change on the occurrence of landslides and their impacts to eco systems. This study shows that most of the landslides occurring in Sri Lanka during northeast monsoons,southwest monsoons and second inter-monsoon were located in three distinctively separated areas. Analysis of rainfall time series shows a trend of increased lengths of dry periods along with an increasing trend of rainfall intensity, especially after the late seventies.A strong relation is obtained between the location of landslides and the spatial distribution of areas where rainfall intensity is increased.

    Here, we describe a 3-month-old XX male French Bulldog. The diagnosis was based on the clinical signs, gonadal histology and cytogenetic analysis. Additionally, the dog was confirmed to be Sry negative by semi-quantitative reverse transcription polymerase chain reaction (sqRT-PCR). Canine Sry-negative XX sex reversal is a disorder of gonadal development where individuals who have a female karyotype develop testes or ovotestes. To our knowledge, this case is the first XX male sex reversion described in a French Bulldog.

  9. A comparison of health state utility values associated with oral potentially malignant disorders and oral cancer in Sri Lanka assessed using the EQ-5D-3 L and the EORTC-8D.

    2016-07-11

    It has been suggested that the EQ-5D-3 L preference-based measure of health outcome lacks sensitivity to discriminate between health states in cancer patients. An alternative approach is to use a disease (cancer) specific preference-based measure, such as the EORTC-8D. A limited number of comparisons have been made between generic and disease specific preference-based measures. The aim of this study was to compare the utility scores from the EQ-5D-3 L and the EORTC-8D in a group of patients with oral cancer or with oral potentially malignant disorders (OPMD). Patients (n = 151) with OPMD or oral cancer were recruited consecutively from six hospitals in Sri Lanka. All participants completed both the EQ-5D-3 L and the EORTC's QLQC-30 instrument. The Sri Lankan EQ-5D-3 L and EORTC-8D scoring algorithms were employed to estimate utility scores. The utility scores from the two instruments were compared for discrimination, responsiveness and correlation. There were significant differences across the two utility scores. The EQ-5D-3 L showed better discrimination than EORTC-8D with higher effect sizes. There were higher ceiling effects observed in the EQ-5D-3 L. There was poor correlation between the dimensions of the two instruments except for the mobility and physical functions. The two instruments captured different aspects of quality of life. The EQ-5D-3 L demonstrated better discrimination than the EORTC-8D. In mild conditions EORTC-8D was more responsive and we recommend further validation of this instrument in diverse cancer conditions.

  10. SRY interacts with ribosomal proteins S7 and L13a in nuclear speckles.

    2011-05-01

    The SRY (sex-determining region on the Y chromosome) is essential for male development; however, the molecular mechanism by which the SRY induces testis development is still unclear. To elucidate the mechanism of testis development, we identified SRY-interacting proteins using a yeast two-hybrid system. We found two ribosomal proteins, RPS7 (ribosomal protein S7) and RPL13a (ribosomal protein L13a) that interact with the HMG (high-mobility group) box domain of SRY. Furthermore, we confirmed the intracellular distributions of RPS7, RPL13a and SRY and found that the three proteins were co-expressed in COS1 cells. SRY, RPS7 and RPL13a were co-localized in nuclear speckles. These findings suggest that SRY plays an important role in activities associated with nuclear speckles via an unknown mechanism.

  11. Mithuri users surveyed in Sri Lanka.

    Science.gov (United States)

    1983-01-01

    The Family Planning Association (FPA) of Sri Lanka completed a survey of Mithuri (oral contraceptive) users to determine consumer characteristics. The survey addressed issues such as purchasing habits, user patterns, dealer consumer relationships, levels of consumer satisfaction and motivation, prevalence of side effects, degree and level of medical consultations, and attitudes toward mass media product advertising. A mail survey was used to conduct this quantitative research to reduce the cost of collecting the data. Mail surveys offer the advantage of being able to reach a large number of respondents at a very reasonable cost, but they also require an accurate list of respondents who are representative of the population to be examined. Of the 681 questionnaires delivered, 442 were completed and returned. The majority of those surveyed (86%) purchased Mithuri at pharmacies that are within 5 miles of their residence. 73.2% of the women asked their husbands to make the purchase, and 67.6% purchased 2 cycles at a time. Most respondents reported experiencing no side effects from Mithuri. The majority of the few who experienced side effects considered them to be very slight. 2.7% of the respondents reported becoming pregnant while using Mithuri, 11 of whom ascribed the pregnancy to their failure to take the pill regularly. Most respondents said that they never missed a day. Husbands or "Western" medical practitioners were most often cited as the motivators to use Mithuri. Of the 82% of the respondents who had read the Mithuri newspaper advertisements, 87% indicated they approved of mass media advertising about contraceptives, primarily because they felt that making such information available was an urgent matter. Although advertisements and package circulars urged 1st time users to consult a physician before using Mithuri, less than half the respondents reported consulting any medical person, nurses, and midwives included. They also reported that the dealer gave no

  15. Potential of Biomass Based Electricity Generation in Sri Lanka

    KP Ariyadasa

    2015-12-01

    Full Text Available Biomass has attracted much attention as a primary energy source for electricity generation due to its potential to supply low cost fuel source with considerable environmental and socio-economic benefits. Despite having favorable climatic conditions to grow and use biomass for electricity generation, biomass based electricity generation in Sri Lanka is lagging behind due to many reasons. Many countries rely on the agricultural or forestry by-products or residuals as the main source of biomass for electricity generation mainly due to the comparatively low cost and sustainable supply of these by-products. Sri Lanka does not have this advantage and has to rely mainly on purposely grown biomass for electricity generation. Development of short rotation energy plantations seems to be the best option available for Sri Lanka to produce biomass for commercial scale electricity generation. The highly favorable growing conditions, availability of promising tree species and a variety of plantation management options and significant environmental and socio-economic benefits associated with energy plantation development greatly favor this option. This paper examines the potential of using plantation grown biomass as a fuel source for electricity generation in Sri Lanka.

    Debashish Banerji

    2013-09-01

    Full Text Available Sri Aurobindo’s teachings on Integral Yoga are couched in a universal and impersonal language, and could be considered an early input to contemporary transpersonal psychology. Yet, while he was writing his principal works in English, he was also keeping a diary of his experiences and understandings in a personal patois that hybridized English and Sanskrit. A hermeneutic perusal of this text, The Record of Yoga, published by the Sri Aurobindo Ashram, uncovers the semiotics of Indian yoga traditions, showing how Sri Aurobindo utilizes and furthers their discourse, and where he introduces new elements which may be considered “modern.” This essay takes a psycho-biographical approach to the life of Sri Aurobindo (1872-1950, tracing his encounters with texts and situated traditions of Indian yoga from the period of his return to India from England (1893 till his settlement in Pondicherry (1910, to excavate the traditional roots and modern ruptures of his own yoga practice, which goes to inform his non-sectarian yoga teachings.

  20. Practice of forensic medicine and pathology in Sri Lanka.

    Balachandra, A Thambirajah; Vadysinghe, Amal N; William, Anita L

    2011-02-01

    The practice of forensic medicine and pathology in Sri Lanka is based on the British model. Medical students during their third and fourth years receive approximately 50 hours of lectures and tutorials in forensic medicine and pathology and then undergo an examination. After completing an internship, these doctors are sent to various hospitals throughout Sri Lanka where they may be asked to perform medicolegal examinations on victims and suspects in rape cases, persons suspected of being under the influence of drugs and/or alcohol, and, injured live patients. As well, they may be asked to perform medicolegal autopsies. Depending upon their experience, some medical officers may be designated as judicial medical officers and appointed full time to do medicolegal work. Up until 1980, judicial medical officers with at least 2 years of work experience were allowed to obtain their postgraduate qualifications in the United Kingdom. However, since 1981 and the establishment of its own Postgraduate Institute of Medicine in Colombo, Sri Lanka, medical officers are offered 2 postgraduate programs in forensic medicine and pathology, a diploma in legal medicine and a doctorate in medicine (forensic medicine). After completing the doctorate in forensic medicine, doctors are allowed to train abroad for a further year in an approved center. Upon return they can then be appointed as consultant judicial medical officers. The practice of forensic medicine and pathology in Sri Lanka is unique and vibrant. However, due to the country's prevailing civil war, the practice of forensic medicine and pathology is suboptimal.

    2015-09-01

    Road traffic accidents are a major public health concern in Sri Lanka. Aggressive and reckless driving is an important contributor to the high rate of road traffic accidents. We studied prevalence, nature, determinants and associated psychiatric morbidity of road rage among motorists in Sri Lanka. Methods Data were gathered from 238 randomly selected motorists in Sri Lanka using a modified questionnaire regarding road rage and the 6-item version of Kessler's psychological distress scale. While 98.7% participants reported being victims of road rage, 85.3% were involved in offending behaviour. However actual physical assault (0.8%) and damage to vehicles (2.5%) were rare. Male gender, young age, increased traffic density and driving a three-wheeler or bus were associated with daily road rage victimisation and perpetration. Psychiatric distress was associated with being a victim of road rage. High prevalence of road rage in Sri Lanka and significant psychiatric distress associated with it indicate the necessity of interventions at least for target groups.

  4. Misoprostol and the politics of abortion in Sri Lanka.

    Science.gov (United States)

    Kumar, Ramya

    2012-12-01

    Misoprostol, a WHO essential medicine indicated for labour induction, management of miscarriage and post-partum haemorrhage, as well as for induced abortion and treatment of post-abortion complications, came up for registration in Sri Lanka in December 2010. The decision on registration was postponed, indefinitely. This has wide-ranging implications, as misoprostol is widely available and used, including by health professionals in Sri Lanka, without guidance or training in its use. This paper attempts to situate the failure to register misoprostol within the broader context of unsafe abortion, drawing on data from interviews with physicians and health policymakers in Sri Lanka. It demonstrates how personal opposition to abortion infiltrates policy decisions and prevents the issue of unsafe abortion being resolved. Any move to reform abortion law and policy in Sri Lanka will require a concerted effort, spearheaded by civil society. Women and communities affected by the consequences of unsafe abortion need to be involved in these efforts. Regardless of the law, women will access abortion services if they need them, and providers will provide them. Decriminalizing abortion and registering abortion medications will make provision of abortion services safer, less expensive and more equitable. Copyright © 2012 Reproductive Health Matters.

    2017-01-01

    An alarming increase in chronic kidney disease with unknown etiology (CKDu) has recently been reported in several provinces in Sri Lanka and chronic exposures to toxic trace elements were blamed for the etiology of this disease. Keratinized matrices such as hair and nails were investigated to determine the possible link between CKDu and toxic element exposures. Elements Li, B, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba, Hg and Pb of hair and nails of patients and age that matched healthy controls were determined with Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The results showed that trace element contents in the hair of patients varies in the order of Zn>Fe>Al>Mn>Cu>Ba>Sr>Ni>Pb>Cr>B>Hg>Se>Mo>Co>As>Li>Cd while Fe>Al>Zn>Ni>Cu>Mn>Cr>Ba>Sr>B>Pb>Se>Mo>Co>Hg>Li>As>Cd in nail samples. The hair As levels of 0.007-0.165μgg(-1) were found in CKDu subjects. However, no significant difference was observed between cases and controls. The total Se content in hair of CKDu subjects ranged from 0.043 to 0.513μgg(-1) while it was varied from 0.031 to 1.15μgg(-1) in controls. Selenium in nail samples varied from 0.037μgg(-1) to 4.10μgg(-1) in CKDu subjects and from 0.042μgg(-1) to 2.19μgg(-1) in controls. This study implies that substantial proportions of Sri Lankan population are Se deficient irrespective of gender, age and occupational exposure. Although some cutaneous manifestations were observed in patient subjects, chemical analyses of hair and nails indicated that patients were not exposed to toxic levels of arsenic or the other studied toxic elements. Therefore the early suggested causative factors such as exposure to environmental As and Cd, can be ruled out. Copyright © 2016 Elsevier GmbH. All rights reserved.

  9. RFI Mitigation Workshop

    Science.gov (United States)

    2010-05-01

    The increased sensitivity of passive instrumentation in radio astronomy and remote sensing and the intensifying active use of the spectrum have led to an increasing level of radio frequency interference (RFI) of the active services on the passive use of the spectrum. Advances in technology and computing have opened up new possibilities for mitigating the effects of certain classes of interference in the observing data. Interference in allocated bands always leads to data loss for the passive users of the spectrum even if interference mitigation is applied. However, interference mitigation in non-allocated spectral bands may facilitate the partial use of this spectrum for passive (non-interfering) observations. There is no generic method to mitigate all types of interference, so a multi-layered system approach may be advisable to reduce detrimental effects for a congested interference environment. Specific mitigation methods implemented at different points in the data acquisition chain will thus result in a cumulative mitigation effect on the data. This third RFI Mitigation Workshop considered RFI mitigation in radio astronomy in all its facets with the aim of facilitating the implementation of instrumental and data processing techniques. This workshop aimed to take a forward look at applications for the next generation of radio instruments, such as the SKA and its pathfinders and LOFAR, as well as considering their application to existing instruments. This workshop has been organized by ASTRON and NAIC, with support from the Engineering Forum of FP7 RadioNet, the SKA Project Development Office, and in collaboration with CRAF and IUCAF.

  10. Delivery of sry1, but not sry2, to the kidney increases blood pressure and sns indices in normotensive wky rats

    2009-06-01

    Full Text Available Abstract Background Our laboratory has shown that a locus on the SHR Y chromosome increases blood pressure (BP in the SHR rat and in WKY rats with the SHR Y chromosome (SHR/y rat. A candidate for this Y chromosome hypertension locus is Sry, a gene that encodes a transcription factor responsible for testes determination. The SHR Y chromosome has six divergent Sry loci. The following study examined if exogenous Sry1 or Sry2 delivered to the kidney would elevate renal tyrosine hydroxylase, renal catecholamines, plasma catecholamines and telemetered BP over a 28 day period. We delivered 50 μg of either the expression construct Sry1/pcDNA 3.1, Sry2/pcDNA 3.1, or control vector into the medulla of the left kidney of normotensive WKY rats by electroporation. Weekly air stress was performed to determine BP responsiveness. Separate groups of animals were tested for renal function and plasma hormone patterns and pharmacological intervention using alpha adrenergic receptor blockade. Pre-surgery baseline and weekly blood samples were taken from Sry1 electroporated and control vector males for plasma renin, aldosterone, and corticosterone. BP was measured by telemetry and tyrosine hydroxylase and catecholamines by HPLC with electrochemical detection. Results In the animals receiving the Sry1 plasmid there were significant increases after 21 days in resting plasma norepinephrine (NE, 27% and renal tyrosine hydroxylase content (41%, p Sry1 (143 mmHg, p Sry1 (41 mmHg compared to controls (28 mmHg, p Sry2 did not elevate BP or SNS indices and further tests were not done. The hormone profiles for plasma renin, aldosterone, and corticosterone between electroporated Sry1 and control vector males showed no significant differences over the 28 day period. Alpha adrenergic receptor blockade prevented the air stress pressor response in both strains. Urinary dopamine significantly increased after 7 days post Sry electroporation. Conclusion These results are consistent

    Full Text Available Sri Lanka occupies a unique location within the equatorial belt in the northern Indian Ocean with the Arabian Sea on its western side and the Bay of Bengal on its eastern side. The region is characterised by bi-annually reversing monsoon winds resulting from seasonal differential heating and cooling of the continental land mass and the ocean. This study explored elements of the dynamics of the surface circulation and coastal upwelling in the waters around Sri Lanka using satellite imagery and the Regional Ocean Modelling System (ROMS configured to the study region and forced with ECMWF interim data. The model was run for 2 yr to examine the seasonal and shorter term (∼10 days variability. The results confirmed the presence of the reversing current system in response to the changing wind field: the eastward flowing Southwest Monsoon Current (SMC during the Southwest (SW monsoon transporting 11.5 Sv and the westward flowing Northeast Monsoon Current (NMC transporting 9.5 Sv during the Northeast (NE monsoon, respectively. A recirculation feature located to the east of Sri Lanka during the SW monsoon, the Sri Lanka Dome, is shown to result from the interaction between the SMC and the Island of Sri Lanka. Along the eastern and western coasts, during both monsoon periods, flow is southward converging along the south coast. During the SW monsoon the Island deflects the eastward flowing SMC southward whilst along the east coast the southward flow results from the Sri Lanka Dome recirculation. The major upwelling region, during both monsoon periods, is located along the south coast and is shown to be due to flow convergence and divergence associated with offshore transport of water. Higher surface chlorophyll concentrations were observed during the SW monsoon. The location of the flow convergence and hence the upwelling centre was dependent on the relative strengths of wind driven flow along the east and west coasts: during the SW (NE monsoon the flow

    Molding. The Lanka Rainwater Harvesting Forum was in need of volumetric estimation of rainfall-runoff contributed to recharge of the aquifers. Regular reporting of high quality rainfall events and intensity is still a challenge to be addressed in Sri Lanka. A combination of OSHW and FOSS is being used to created a royalty-free, cheap raingauge design, with full control of on-board data collection and statistics. Development of an initial 15 raingauges include capacity-building, joint set up from the ground to scouting and installation, and full ownership of all aspects (hardware sourcing locally, software modification, communication troubleshooting, etc.). The Irrigation Department in Malwatu Oya had a requirement for real time rainfall information to manage reservoirs in cascade ("daisy chain") and mitigate flooding consequences downstream. 5 generic prototypes are now reporting to reservoir managers, and the reservoir management model is now rerun as often as needed to re-assess decision-requirements from any new rainfall about certain, already-known, dangerous intensity. The irrigation department capacity-building was provided in two trainings, one for engineers (decision-making support) and technicians (reporting and maintenance). Interest for further level of control in the system is low. Reporting online is following several potential routes, and an open design GPRS protocol is being developed, to simplify future weather stations design specifications in Sri Lanka.

    1985-10-01

    This paper gives an informatory account of the development of micro-catchments in Sri Lanka for irrigation. Information for the paper comes from the experience of detailed investigation and preparation of technical proposals for the improvement of 170 existing micro-scale reservoir schemes in the Puttalam and Kurunegala districts, over a period of three years (January, 1982 through December, 1984), under a World Bank-financed project called "Integrated Rural Development (IRD) Project". Investigations were carried out by a private body called Planning Consultancy, a professional staff comprising a team of eight engineers from the Resources Development Consultants Ltd., Sir Lanka, under a contract with the Ministry of Plan Implementation and under the supervision of the Irrigation Department of Sri Lanka and a World Bank-recommended body called Supervisory Consultancy. The writer is a member of the Planning Consultancy team who personally investigated and designed 30 of these schemes.

    The Central Bank of Sri Lanka has increasingly been relying on interest rates as the instrument for conducting monetary policy. Changes to the key monetary policy variables, the Repo and the Reverse Repo rates, are initially expected to be reflected in the OMO rates and the call money market rates, before being passedthrough to commercial bank retail interest rates. It is important to obtain a good understanding of the speed and magnitude of the interest rate pass-through to make timely monet...

  19. EXPANSION OF UNIVERSITY EDUCATION, GRADUATE UNEMPLOYMENT AND THE KNOWLEDGE HUB IN SRI LANKA

    Gamini Samaranayake

    2016-04-01

    Full Text Available The main objective of this paper is to examine the nexus between the existing university education system and graduate unemployment, and to explore the responses of successive governments to address this issue. It also examines the viability and potential of the knowledge hub as a solution to graduate unemployment. Towards this end, it argues that the solution to graduate employment lies in implementing structural changes that are concurrent to changes that are taking place at the international level in higher education. It illustrates, with the use of relevant sources, the pressing issue of graduate un- and underemployment, and identifies the mismatch between skills and requirements as a major factor contributing to intensify the crisis. It observes that strategies such as training unemployed graduates to enable them to acquire the competencies needed for the modern work place, developing systems to link them to the world of work, re-structuring the university system such that it is more concerned with quality and relevance rather than the width of knowledge imparted, and introducing job-oriented programmes could partially address this issue. It also identifies the proposal to establish a knowledge hub in Sri Lanka as constituting a long term and sustainable strategy not only to mitigate the effects of graduate un- and underemployment, but also to facilitate a lucrative source of revenue for the country.

    Adult flukes of Paragonimus species were obtained from lungs of experimental animals infected with metacercariae found in field-collected freshwater crabs in Sri Lanka. Morphological studies of adult worms under a scanning electron microscope as well as a ordinary microscope were performed in the present study. All of morphological features observed clearly indicated that this species is P. westermani. On the other hand, the shapes of metacercariae were found to be mainly oval, but semioval and spherical ones also coexisted. In spite of the variety of their morphology of the metacercariae, there is no correlation between their shapes of metacercariae and the deoxyribonucleic acid (DNA) sequences. Molecular phylogenetic analyses using two DNA regions (partial mitochondrial cytochrome c oxidase subunit 1 and second internal transcribed spacer of the nuclear ribosomal gene repeat) placed the adult flukes of P. westermani from Sri Lanka basal in a tree including all specimens of P. westermani from various areas in Asia and P. siamensis from Thailand. The present study showed that P. westermani from Sri Lanka is an ancestral form.

    A strontium iodide crystal doped by europium (SrI2(Eu)) was produced by using the Stockbarger growth technique. The crystal was subjected to characterisation that included relative photoelectron output and energy resolution for gamma quanta. The intrinsic radioactivity of SrI2(Eu) crystal scintillator was tested both in scintillation mode and by using ultra-low background HPGe gamma spectrometry deep underground. The response of the SrI2(Eu) detector to alpha particles (alpha/beta ratio and pulse shape) was estimated by analysing the 226Ra trace contamination internal to the crystal. We have found alpha/beta=0.55 and no difference in scintillation decay for alpha particles and gamma quanta. The application of the obtained results in the search for the double electron capture and electron capture with positron emission in 84Sr has been investigated at a level of sensitivity T_1/2 \\sim 10^15-10^16 yr. The results of these studies demonstrate the potentiality of this material for a variety of scintillation appli...

    2008-01-01

    Full Text Available After the 2004 Indian Ocean tsunami inundation event, thin sediment films of fining up sequences were located in several topographic depressions of the southern coastal belt of Sri Lanka. The films consisting of silty fine sand with particular microfossil assemblages were located also in closed containers, bottles and kitchen tables. Well preserved microfossils such as foraminifera, radiolarians as well as spicules of sponges were noted in these recent tsunami sediments.Random augur holes were drilled into some selected depressions in the southern coastal villages of Peraliya and Denuwala situated at locations separated by about 50km. In several such holes, at least two fining up sequences were located below the surface in soil horizons separated from each other by 35cm to 1m. These soil profiles were overlying older coral reefs developed on lateritic formations. The microscopic observations on particular size fractions of the soil horizons showed microfossil assemblages with textures, color and organic C contents strikingly comparable to those observed in the recent tsunami sediments of Sri Lanka. Our findings imply the occurrence of at least two paleo- tsunami events of different ages in Sri Lanka originating apparently from a common source.

  3. From Rat to Human: Regulation of Renin-Angiotensin System Genes by Sry

    Directory of Open Access Journals (Sweden)

    Jeremy W. Prokop

    2012-01-01

    Full Text Available The testis determining protein, Sry, has functions outside of testis determination. Multiple Sry loci are found on the Y-chromosome. Proteins from these loci have differential activity on promoters of renin-angiotensin system genes, possibly contributing to elevation of blood pressure. Variation at amino acid 76 accounts for the majority of differential effects by rat proteins Sry1 and Sry3. Human SRY regulated rat promoters in the same manner as rat Sry, elevating Agt, Ren, and Ace promoter activity while downregulating Ace 2. Human SRY significantly regulated human promoters of AGT, REN, ACE2, AT2, and MAS compared to control levels, elevating AGT and REN promoter activity while decreasing ACE2, AT2, and MAS. While the effect of human SRY on individual genes is often modest, we show that many different genes participating in the renin-angiotensin system can be affected by SRY, apparently in coordinated fashion, to produce more Ang II and less Ang-(1–7.

    2010-01-01

    With the discovery of new exploit techniques, novel protection mechanisms are needed as well. Mitigations like DEP (Data Execution Prevention) or ASLR (Address Space Layout Randomization) created a significantly more difficult environment for exploitation. Attackers, however, have recently researched new exploitation methods which are capable of bypassing the operating system’s memory mitigations. One of the newest and most popular exploitation techniques to bypass both of the aforementioned security protections is JIT memory spraying, introduced by Dion Blazakis. In this article we will present a short overview of the JIT spraying technique and also novel mitigation methods against this innovative class of attacks. An anti-JIT spraying library was created as part of our shellcode execution prevention system.

  6. Delineation of Tsunami Risk Zones for Sri Lanka

    Wijetunge, J. J.

    2008-12-01

    The coastal belts of several Indian Ocean countries including Indonesia, Sri Lanka, India and Thailand suffered massive loss of life and damage to property due to the tsunami unleashed by the great earthquake of moment magnitude 9.1-9.3 in the Andaman-Sunda subduction zone on December 26, 2004. In Sri Lanka, 13 of the 14 administrative districts lying along the coastal belt were affected: the death toll was over 35,000 with 20,000 injured and about 100,000 dwellings and other buildings either completely or partially damaged leaving half a million people homeless and causing massive disruption to livelihoods. However, it was clear in the immediate aftermath of the tsunami that the degree of damage along the coastal belt of Sri Lanka was not uniform: some areas suffered more damage, some less, and in certain other areas, often not far away, there was no damage at all. This suggests that the level of risk for coastal communities from future events of tsunami exhibits considerable variation even along a short stretch of the shoreline. The high cost and the scarcity of coastal lands in many areas demand an accurate assessment of the tsunami risk rather than arbitrary conservative zonation. Moreover, information relating to the spatial distribution of tsunami risk is essential in formulating post-tsunami coastal land use plans as well as in planning of evacuation of people during tsunami warnings. However, neither comprehensive probabilistic assessments of the tsunami hazard nor detailed information pertaining to the vulnerability of coastal communities are available at present for the coastal zone of Sri Lanka. Consequently, the methodology adopted in the present paper is to use field observations and numerical simulations of the December 2004 tsunami, which may be considered a worst-case scenario, in order to obtain the variation along the coastline of three parameters that quantify the tsunami impact. These three parameters are the tsunami height, the horizontal

    Sri Lanka is part of the Western Ghats & Sri Lanka biodiversity hotspot. Thus, the conservation of Sri Lanka's unique biodiversity is crucial. The current study is part of an ongoing survey of pseudoscorpion fauna of Sri Lanka. We carried out an island-wide survey of pseudoscorpions using a range of collection methods to sample a diverse set of habitats around the country. This produced 32 species, four of which might be new to science, belonging to 25 genera. The family Cheiridiidae was discovered on the island for the first time. One new combination, Indogarypus ceylonicus (Beier, 1973) comb. nov., is proposed. Out of the 47 species now recorded, 20 (43 %) are potentially endemic to Sri Lanka. We provide a checklist of all known species, document their distribution and give a key to the families.

    Science.gov (United States)

    Wallis, M C; Waters, P D; Graves, J A M

    2008-10-01

    Therian mammals (marsupials and placentals) have an XX female: XY male sex chromosome system, which is homologous to autosomes in other vertebrates. The testis-determining gene, SRY, is conserved on the Y throughout therians, but is absent in other vertebrates, suggesting that the mammal system evolved about 310 million years ago (MYA). However, recent work on the basal monotreme mammals has completely changed our conception of how and when this change occurred. Platypus and echidna lack SRY, and the therian X and Y are represented by autosomes, implying that SRY evolved in therians after their divergence from monotremes only 166 MYA. Clues to the ancestral mechanism usurped by SRY in therians are provided by the monotremes, whose sex chromosomes are homologous to the ZW of birds. This suggests that the therian X and Y, and the SRY gene, evolved from an ancient bird-like sex chromosome system which predates the divergence of mammals and reptiles 310 MYA.

    2016-05-01

    Spatial and temporal variation of frequencies of thunderstorms over Sri Lanka using thunder day data is presented. A thunder day is simply a calendar day in which thunder is heard at least once at a given location. Two sets of data were collected and analyzed: annual totals for 10 climatological stations for a period of 50 years and monthly totals for 20 climatological stations for a period of 20 years. The average annual thunder days over Sri Lanka was found to be 76. Among the climatological stations considered, a high number of annual thunder days was recorded in Ratnapura (150 days/year), followed by Colombo (108 days/year) and Bandarawela (106 days/year). It appears that there are no widespread long-term increasing or decreasing trends in thunderstorm frequencies. However, Colombo, the capital of Sri Lanka which has over two million people shows an increasing trend of 0.8 thunder days per year. Although there is a high variability between stations reporting the number of thunder days, the overall pattern within a year is clear. Thunderstorm frequencies are high during two periods: March-May and September-November, which coincide with the first inter-monsoon and second inter-monsoon periods. Compared to the dry zone, the wet zone, especially the southwestern region, has high thunderstorm activity. There is a clear spatial difference in thunderstorm activities during the southwest and northeast monsoon seasons. During both these seasons, enhanced thunderstorm activities are reported on the leeward side of the mountain range. A slight reduction in the thunderstorm activities was found in the high elevation areas of the hill country compared to the surrounding areas. A lightning ground flash density map derived using annual thunder days is also presented.

  1. Upgrading graphite by flotation at Bogala Mines in Sri Lanka

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Graphite is naturally floatable due to its hydrophobic property and also soft and smears on other gangue particles, rendering the gangue more or less floatable too. Due to this reason it is important to concentrate on areas such as suitable flotation reagents, depression agents, pH modifiers, and particle size to be fed during the process, The paper surveys and analyses the suitable particle size to be fed to achieve high-grade concentrate. According to the work carried out the author suggested the ideal cost effective flotation flow sheet for improved results at Bogala Mines in Sri Lanka.

    Cutaneous dipththeria is an infectious bacterial disease endemic in tropical regions, but rarely diagnosed in Germany. Following travel in Sri Lanka, a 60-year-old German presented to our dermatological clinic with a skin ulcer and extensive erythematous erosive edema of his left foot. Corynebacterium diphtheriae was isolated from a swab of the lesion. There were no clinical signs of toxic diphtheria. The patient was treated with penicillin G and erythromycin, followed by a slow healing of the lesion. The isolated strain could be identified as toxigenic C. diphtheriae mitis. Due to increased travel activity, dermatologists should have uncommon infections like cutaneous diphtheria in mind.

    The emergence of new, transmissible infections poses a significant threat to human populations. As the 2009 novel influenza A/H1N1 pandemic and the 2014-2015 Ebola epidemic demonstrate, we have observed the effects of rapid spread of illness in non-immune populations and experienced disturbing uncertainty about future potential for human suffering and societal disruption. Clinical and epidemiologic characteristics of a newly emerged infectious organism are usually gathered in retrospect as the outbreak evolves and affects populations. Knowledge of potential effects of outbreaks and epidemics and most importantly, mitigation at community, regional, national and global levels is needed to inform policy that will prepare and protect people. Study of possible outcomes of evolving epidemics and application of mitigation strategies is not possible in observational or experimental research designs, but computational modeling allows conduct of `virtual' experiments. Results of well-designed computer simulations can aid in the selection and implementation of strategies that limit illness and death, and maintain systems of healthcare and other critical resources that are vital to public protection.

    Full Text Available Human-wildlife conflict occurs when human requirements encroach on those of wildlife populations, with potential costs to both humans and wild animals.  As top predators in most inland waters, crocodilians are involved in human-wildlife conflicts in many countries.  Here we present findings of a 5-year survey on human-crocodile conflict on the island of Sri Lanka and relate the results to improving management practices. We aimed to quantify and understand the causes of human-crocodile conflict in Sri Lanka, and propose solutions to mitigate it.  Visual encounter surveys were carried out to estimate the population size of Saltwater Crocodiles. We recorded 778 sightings of Saltwater Crocodiles at 262 of 400 locations surveyed, and estimate the total population to comprise more than 2000 non-hatchlings and to have increased at an average rate of 5% p.a. since 1978. We propose four crocodile vigilance zones within the wet zone and one crocodile vigilance zone within the dry zone of the country. Specific threats to Saltwater Crocodiles identified in crocodile vigilance zones were: habitat destruction and loss; illegal killing and harvesting (17 killings out of fear, ~200 incidents of killing for meat and skins, ~800 eggs annually for consumption; unplanned translocations; and, interaction with urbanization (10 incidents of crocodiles being run over by trains/vehicles and electrocution. Additionally, 33 cases of crocodile attacks on humans were recorded [8 fatal, 25 non-fatal (minor to grievous injuries] and more than 50 incidents of attacks on farm and pet animals. 

  5. Energy and street foods (Bangladesh and Sri Lanka)

    Energy used by street food vendors is effectively replacing fuel consumption in the household, as studies have shown that street foods are often cheaper to buy than to prepare at home. Rapid urbanisation has led to a proliferation of these very small food outlets, particularly in the Asian subcontinent. Street foods provide employment and income to millions of people around the world, and provide low cost, affordable food to low income people. The project pilot tested improved biomass stoves with a selection of street food vendors. In Sri Lanka, laboratory tests were undertaken with the following three stoves: improved rice-husk burner, biomass gasifier, and double-mouth chimney stoves. From the pilot testing in Sri Lanka the key findings are that the efficient gasifier stove is not suitable for street food vendors, but there were some promising results from larger biomass stoves. In Bangladesh, the project piloted four types of biomass stove: single mouth, double mouth, bucket-type and institutional stove. As these were more established, the pilot focused on a method for reaching a larger number of beneficiaries, people were trained to make stoves in their own and in others' houses. Five workshops were held and over 540 stoves were built. Impact assessment exercises were undertaken in both countries. (author)

  6. Musculoskeletal trauma services in Mozambique and Sri Lanka.

    2008-10-01

    There is currently an escalating epidemic of trauma-related injuries due to road traffic accidents and armed conflicts. This trauma occurs predominantly in rural areas where most of the population lives. Major ways to combat this epidemic include prevention programs, improved healthcare facilities, and training of competent providers. Mozambique and Sri Lanka have many common features including size, economic system, and healthcare structure but have significant differences in their medical education systems. With six medical schools, Sri Lanka graduates 1000 new physicians per year while Mozambique graduates less than 50 from their singular school. To supplement the low number of physicians, a training course for surgical technicians has been implemented. Examination of district hospital staffing and the medical education in these two countries might provide for improving trauma care competence in other developing countries. Musculoskeletal education is underrepresented in most medical school curricula around the world. District hospitals in developing countries are commonly staffed by recently graduated general medical officers, whose last formal education was in medical school. There is an opportunity to improve the quality of trauma care at the district hospital level by addressing the musculoskeletal curriculum content in medical schools.

  7. Marine protected areas in Sri Lanka: a review.

    2007-11-01

    Despite the popularity of marine protected areas (MPAs) as a management tool, increasing evidence shows that many fail to achieve conservation objectives. Although several MPAs exist in Sri Lanka, most are not managed, and resource extraction and habitat degradation continue unabated. At present, the declaration and management of MPAs is carried out without adequate consideration of the ecology, socioeconomic realities, or long-term management sustainability. Managers have focused more toward the creation of new legislation and protected areas rather than ensuring the implementation of existing regulations and management of existing protected areas. Poor coordination and a lack of serious political will have also hindered successful resource management. As in other developing countries, MPA managers have to contend with coastal communities that are directly dependant on marine resources for their subsistence. This often makes it unfeasible to exclude resource users, and MPAs have failed to attract necessary government support because many politicians are partial toward the immediate needs of local communities for both economic and political reasons. A more integrated approach, and decisions based on the analysis of all relevant criteria combined with a concerted and genuine effort toward implementing strategies and achieving predetermined targets, is needed for effective management of MPAs and the sustainable use of marine resources in Sri Lanka.

    Full Text Available Plant poisoning is a common presentation in paediatric practice and an important cause of preventable mortality and morbidity in Sri Lanka. The burden of plant poisoning is largely underexplored. The current multicenter study based in rural Sri Lanka assessed clinical profiles, poison related factors, clinical management, complications, outcomes, and risk factors associated with plant poisoning in the paediatric age group. Among 325 children, 57% were male with 64% being below five years of age. 99.4% had ingested the poison. Transfer rate was 66.4%. Most had unintentional poisoning. Commonest poison plant was Jatropha circus and poisoning event happened mostly in home garden. 29% of parents practiced harmful first-aid practices. 32% of children had delayed presentations to which the commonest reason was lack of parental concern regarding urgency of seeking medical care. Presence of poisonous plants in home garden was the strongest risk factor for plant poisoning. Mortality rate was 1.2% and all cases had Oleander poisoning. The study revealed the value of community awareness regarding risk factors and awareness among healthcare workers regarding the mostly benign nature of plant poisoning in children in view of limiting incidence of plant poisoning and reducing expenditure on patient management.

    Full Text Available Background: Internet-based media coverage to explore the extent of awareness of a disease and perceived severity of an outbreak at a national level can be used for early outbreak detection. Dengue has emerged as a major public health problem in Sri Lanka since 2009. Objective: To compare Internet references to dengue in Sri Lana with references to other diseases (malaria and influenza in Sri Lanka and to compare Internet references to dengue in Sri Lanka with notified cases of dengue in Sri Lanka. Design: We examined Internet-based news media articles on dengue queried from HealthMap for Sri Lanka, for the period January 2007 to November 2015. For comparative purposes, we compared hits on dengue with hits on influenza and malaria. Results: There were 565 hits on dengue between 2007 and 2015, with a rapid rise in 2009 and followed by a rising trend ever since. These hits were highly correlated with the national epidemiological trend of dengue. The volume of digital media coverage of dengue was much higher than of influenza and malaria. Conclusions: Dengue in Sri Lanka is receiving increasing media attention. Our findings underpin previous claims that digital media reports reflect national epidemiological trends, both in annual trends and inter-annual seasonal variation, thus acting as proxy biosurveillance to provide early warning and situation awareness of emerging infectious diseases.

    Introduction. In 2011, following heavy winter snowfall, two cities bordering two rivers in North Dakota, USA faced major flood threats. Flooding was foreseeable and predictable although the extent of risk was uncertain. One community, Fargo, situated in a shallow river basin, successfully mitigated and prevented flooding. For the other community, Minot, located in a deep river valley, prevention was not possible and downtown businesses and one-quarter of the homes were inundated, in the city’s worst flood on record. We aimed at contrasting the respective hazards, vulnerabilities, stressors, psychological risk factors, psychosocial consequences, and disaster risk reduction strategies under conditions where flood prevention was, and was not, possible. Methods. We applied the “trauma signature analysis” (TSIG) approach to compare the hazard profiles, identify salient disaster stressors, document the key components of disaster risk reduction response, and examine indicators of community resilience. Results. Two demographically-comparable communities, Fargo and Minot, faced challenging river flood threats and exhibited effective coordination across community sectors. We examined the implementation of disaster risk reduction strategies in situations where coordinated citizen action was able to prevent disaster impact (hazard avoidance) compared to the more common scenario when unpreventable disaster strikes, causing destruction, harm, and distress. Across a range of indicators, it is clear that successful mitigation diminishes both physical and psychological impact, thereby reducing the trauma signature of the event. Conclusion. In contrast to experience of historic flooding in Minot, the city of Fargo succeeded in reducing the trauma signature by way of reducing risk through mitigation. PMID:28228985

    Highly hazardous organophosphorus (OP) insecticides are responsible for most pesticide poisoning deaths. As they are removed from agricultural practice, they are often replaced by carbamate insecticides of perceived lower toxicity. However, relatively little is known about poisoning with these insecticides. We prospectively studied 1288 patients self-poisoned with carbamate insecticides admitted to six Sri Lankan hospitals. Clinical outcomes were recorded for each patient and plasma carbamate concentration measured in a sample to confirm the carbamate ingested. Patients had ingested 3% carbofuran powder (719), carbosulfan EC25 liquid (25% w/v, 389), or fenobucarb EC50 liquid (50% w/v, 127) formulations, carbamate insecticides of WHO Toxicity Classes Ib, II, and II, respectively. Intubation and ventilation was required for 183 (14.2%) patients while 71 (5.5%) died. Compared with carbofuran, poisoning with carbosulfan or fenobucarb was associated with significantly higher risk of death [carbofuran 2.2%; carbosulfan 11.1%, OR 5.5 (95% CI 3.0-9.8); fenobucarb 6.3%, OR 3.0 (1.2-7.1)] and intubation [carbofuran 6.1%; carbosulfan 27.0%, OR 5.7 (3.9-8.3); fenobucarb 18.9%, OR 3.6 (2.1-6.1)]. The clinical presentation and cause of death did not differ markedly between carbamates. Median time to death was similar: carbofuran 42.3 h (IQR 5.5-67.3), carbosulfan 21.3 h (11.5-71.3), and fenobucarb 25.3 h (17.3-72.1) (p = 0.99); no patients showed delayed onset of toxicity akin to the intermediate syndrome seen after OP insecticide poisoning. For survivors, median duration of intubation was 67.8 h (IQR 27.5-118.8) with no difference in duration between carbamates. Reduced GCS at presentation was associated with worse outcome although some patients with carbosulfan died after presentation with normal GCS. We did not find carbamate insecticide self-poisoning to vary markedly according to the carbamate ingested although the case fatality varied according to the

  15. Molecular mechanism of male differentiation is conserved in the SRY-absent mammal, Tokudaia osimensis

    OpenAIRE

    2016-01-01

    The sex-determining gene SRY induces SOX9 expression in the testes of eutherian mammals via two pathways. SRY binds to testis-specific enhancer of Sox9 (TESCO) with SF1 to activate SOX9 transcription. SRY also up-regulates ER71 expression, and ER71 activates Sox9 transcription. After the initiation of testis differentiation, SOX9 enhances Amh expression by binding to its promoter with SF1. SOX8, SOX9 and SOX10, members of the SOXE gene family, also enhance the activities of the Amh promoter a...

    Full Text Available Abstract Background Sry is a gene known to be essential for testis determination but is also transcribed in adult male tissues. The laboratory rat, Rattus norvegicus, has multiple Y chromosome copies of Sry while most mammals have only a single copy. DNA sequence comparisons with other rodents with multiple Sry copies are inconsistent in divergence patterns and functionality of the multiple copies. To address hypotheses of divergence, gene conversion and functional constraints, we sequenced Sry loci from a single R. norvegicus Y chromosome from the Spontaneously Hypertensive Rat strain (SHR and analyzed DNA sequences for homology among copies. Next, to determine whether all copies of Sry are expressed, we developed a modification of the fluorescent marked capillary electrophoresis method to generate three different sized amplification products to identify Sry copies. We applied this fragment analysis method to both genomic DNA and cDNA prepared from mRNA from testis and adrenal gland of adult male rats. Results Y chromosome fragments were amplified and sequenced using primers that included the entire Sry coding region and flanking sequences. The analysis of these sequences identified six Sry loci on the Y chromosome. These are paralogous copies consistent with a single phylogeny and the divergence between any two copies is less than 2%. All copies have a conserved reading frame and amino acid sequence consistent with function. Fragment analysis of genomic DNA showed close approximations of experimental with predicted values, validating the use of this method to identify proportions of each copy. Using the fragment analysis procedure with cDNA samples showed the Sry copies expressed were significantly different from the genomic distribution (testis p Sry transcript expression, analyzed by real-time PCR, showed significantly higher levels of Sry in testis than adrenal gland (p, 0.001. Conclusion The SHR Y chromosome contains at least 6 full length

    This report discussed issues related to farm stray voltage and evaluated mitigation strategies and costs for limiting voltage to farms. A 3-phase, 3-wire system with no neutral ground was used throughout North America before the 1930s. Transformers were connected phase to phase without any electrical connection between the primary and secondary sides of the transformers. Distribution voltage levels were then increased and multi-grounded neutral wires were added. The earth now forms a parallel return path for the neutral current that allows part of the neutral current to flow continuously through the earth. The arrangement is responsible for causing stray voltage. Stray voltage causes uneven milk production, increased incidences of mastitis, and can create a reluctance to drink water amongst cows when stray voltages are present. Off-farm sources of stray voltage include phase unbalances, undersized neutral wire, and high resistance splices on the neutral wire. Mitigation strategies for reducing stray voltage include phase balancing; conversion from single to 3-phase; increasing distribution voltage levels, and changing pole configurations. 22 refs., 5 tabs., 13 figs.

    Full Text Available The Sumatra Earthquake and Indian Ocean Tsunami event on the 26 December 2004 has provided a unique and valuable opportunity to evaluate the performance of various structures, facilities and lifeline systems during the tsunami wave attacks. There are especially meaningful observations concerning the structural changes due to the tsunami forces, which open up a wide area of research to develop the mitigation procedure. The business restoration process of business companies in terms of buildings, facilities and lifelines have shown greater research interest. In this study, we investigated the restoration process of business sectors in East and South coastal region in Sri Lanka after the 2004 Indian Ocean Tsunami. A field survey was conducted in East and South coast of Sri Lanka, in order to study the affecting parameters to damage assessment in the restoration process of the business companies. The results of the questionnaire-based field survey are then compared with the statistical analysis results. Finally, the factors affecting the restoration process after the tsunami are identified. As a main conclusion, financial support could be the most important reason for delays in restoration. Moreover, it has been observed that the tsunami inundation level of higher than one meter may have had more effect concerning the damage to the structures and requires additional time for restoration than other areas.

    In the light of Sri Aurobindo's philosophy, this paper looks into some of the problems of contemporary man as an individual, a member of society, a citizen of his country, a component of this world, and of nature itself. Concepts like Science; Nature,;Matter; Mental Being; Mana-purusa; Prana-purusa; Citta-purusa; Nation-ego and Nation-soul; True and False Subjectivism; World-state and World-union; Religion of Humanism are the focus of this paper. NATURE: Beneath the diversity and uniqueness of the different elements in Nature there is an essential unity that not only allows for this diversity but even supports it. Nature is both a benefactor and a force: a benefactor, because it acts to carry out the evolution of mankind; a force, because it also supplies the necessary energy and momentum to achieve it. NATURAL CALAMITIES: If mankind can quieten the tsunamis and cyclones and droughts and earthquakes that rage within, and behave with care and compassion towards Nature, not exploiting, denuding, or denigrating it, there is a strong possibility that Nature too will behave with equal care and compassion towards man and spare him the natural calamities than rend him asunder. SCIENCE: The limitation of science become obvious, according to Sri Aurobindo, when we realize that it has mastered knowledge of processes and helped in the creation of machinery but is ignorant of the foundations of being and, therefore, cannot perfect our nature or our life. SCIENCE AND PHILOSOPHY: The insights of philosophy could become heuristic and algorithmic models for scientific experimentation. MATTER: An interesting aspect of Sri Aurobindo's philosophy is his acceptance of the reality of matter even while highlighting its inadequacies; the ultimate goal, according to him, is the divination of matter itself.

    Full Text Available We conducted a bird survey in the Sabaragamuwa University premises in southeastern Sri Lanka between 2001 and 2004. We recorded 145 bird species, representing 17 orders and 51 families from the campus. The birdlife included Red-faced Malkoha, a globally Vulnerable species and four Near Threatened taxa. The university premises suffer from severe habitat alteration largely owing to fire, filling-up of aquatic habitats, resource over-extraction, improper waste management, invasion by exotic species and livestock grazing. Several conservation measures, including habitat management strategies such as restoration of riparian vegetation, and wetlands, increasing plant diversity in home gardens and prevention of secondary successions in grasslands are recommended to protect the campus environment and to conserve its avifaunal diversity.

The focus of national and international post tsunami malaria control efforts was supply of antimalarials, distribution of impregnated mosquito nets...... and increased monitoring in the affected area. Internationally donated antimalarials were either redundant or did not comply with national drug policy, however, few seem to have entered circulation outside government control. Despite distribution of mosquito nets, still a large population is relatively exposed...... to mosquito bites due to inadequate housing. There were no indications of increased malaria vector abundance. Overall it is concluded that the tsunami has not negatively influenced the malaria situation in Sri Lanka....

    On December 29, 2012, a bright yellow and green fireball was observed to disintegrate over the Polonnaruwa District of North Central, Sri Lanka. Many low density, black stones were recovered soon after the observed fall from rice paddy fields near the villages of Aralaganwila and Dimbulagala. These stones were initially studied by optical microscopy methods at the Medical Research Institute in Colombo, Sri Lanka. Soon thereafter, samples were sent to the UK and to the United States. More extensive Field Emission Scanning Electron Microscopy studies were then carried out at Cardiff University and the NASA/Marshall Space Flight Center. The physico-chemical properties, elemental abundances, mineralogy and stable isotope data clearly indicate that these stones are non-terrestrial. Freshly fractured interior surfaces of the black stones have also been observed to contain the remains of fossilized diatom. Many of the diatom frustules are clearly embedded in the meteorite rock matrix and exhibit nitrogen levels below the EDX detection limits. Some of the fossil diatoms are araphid marine pennates and planktonic forms that are inconsistent with conditions associated with rice paddy fields. These observations indicate the fossilized diatoms are indigenous to the meteorites rather than post-arrival biological contaminants. The carbon content and mineralogy suggests that these stones may represent a previously ungrouped clan of carbonaceous meteorites. The extremely low density (~0.6) of the stones and their observed mineralogy was inconsistent with known terrestrial rocks (e.g., pumice, diatomite and fulgurites). The minerals detected suggest that the parent body of the Polonnaruwa stones may have been the nucleus of a comet. These observations are interpreted as supporting the Hoyle-Wickramasinghe Panspermia hypothesis and the hypothesis that diatoms and other microorganisms might be capable of living and growing in water ice and brines in comets.

  5. Assessing medication packaging and labelling appropriateness in Sri Lanka.

    There is substantial evidence of poor dispensing practices with inadequate packaging and labelling of medicines, and limited advice on their usage in low and middle-income countries (LMICs). We examined the labelling and packaging of medicines identified during a survey of 1322 households in six regions of Sri Lanka between 2010 and 2013 conducted using the World Health Organization (WHO) methodology for household surveys. We compared medicines obtained from public and private sources and asked interviewees if they understood how to take the medicines. Packaging was considered adequate when the primary package was an envelope or closable container holding only one medicine. Adequate labels were legible and included medicine name, dose and expiration date. Interviewers assessed whether respondents knew how to take the medicines. Of 1322 households, 1253 households (94.8%) had at least one medicine; 84% were classified as western medicines and 16% traditional medicines. Of 5756 western medicines identified, 82.1% were adequately packaged, 43.3% adequately labelled and 41.4% both adequately packaged and labelled. Participants stated that they understood the label and knew how to take 96% of the medicines. Private medicine sources had more adequately packaged medicines than public sources (87.7% vs 73.5%; OR 2.58, 95% CI 2.23, 2.99) and more adequately labelled medicines (52.2% vs 27.4%; OR 2.90, 95% CI 2.57, 3.26). Inadequate packaging and labelling of medicines remain a concern in Sri Lanka. Commitment to Good Pharmacy Practices, investments in staff education and training and adequate dispensing resources (containers and labels), particularly in the public sector, are needed to address sub-optimal dispensing practices. Ageing populations with more chronic diseases requiring polypharmacy and complex medicine regimens increase the need for appropriately packaged and labelled medicines.

  6. Supporting elephant conservation in Sri Lanka through MODIS imagery

    2012-10-01

    The latest national elephant survey of Sri Lanka (2011) revealed Sri Lanka has 5,879 elephants. The total forest cover for these elephants is about 19,500 sq km (2012 estimation) and estimated forest area is about 30% of the country when smaller green patches are also counted. However, studies have pointed out that a herd of elephants need about a 100 sq km of forest patch to survive. With a high human population density (332 people per sq km, 2010), the pressure for land to feed people and elephants is becoming critical. Resent reports have indicated about 250 elephants are killed annually by farmers and dozens of people are also killed by elephants. Under this context, researchers are investigating various methods to assess the elephant movements to address the issues of Human-Elephant-Conflict (HEC). Apart from various local remedies for the issue, the conservation of elephant population can be supported by satellite imagery based studies. MODIS sensor imagery can be considered as a successful candidate here. Its spatial resolution is low (250m x 250m) but automatically filters out small forest patches in the mapping process. The daily imagery helps to monitor temporal forest cover changes. This study investigated the background information of HEC and used MODIS 250m imagery to suggest applicability of satellite data for Elephant conservations efforts. The elephant movement information was gathered from local authorities and potentials to identify bio-corridors were discussed. Under future research steps, regular forest cover monitoring through MODIS data was emphasized as a valuable tool in elephant conservations efforts.

    Full Text Available Abstract Background Malaria in Sri Lanka is unstable and fluctuates in intensity both spatially and temporally. Although the case counts are dwindling at present, given the past history of resurgence of outbreaks despite effective control measures, the control programmes have to stay prepared. The availability of long time series of monitored/diagnosed malaria cases allows for the study of forecasting models, with an aim to developing a forecasting system which could assist in the efficient allocation of resources for malaria control. Methods Exponentially weighted moving average models, autoregressive integrated moving average (ARIMA models with seasonal components, and seasonal multiplicative autoregressive integrated moving average (SARIMA models were compared on monthly time series of district malaria cases for their ability to predict the number of malaria cases one to four months ahead. The addition of covariates such as the number of malaria cases in neighbouring districts or rainfall were assessed for their ability to improve prediction of selected (seasonal ARIMA models. Results The best model for forecasting and the forecasting error varied strongly among the districts. The addition of rainfall as a covariate improved prediction of selected (seasonal ARIMA models modestly in some districts but worsened prediction in other districts. Improvement by adding rainfall was more frequent at larger forecasting horizons. Conclusion Heterogeneity of patterns of malaria in Sri Lanka requires regionally specific prediction models. Prediction error was large at a minimum of 22% (for one of the districts for one month ahead predictions. The modest improvement made in short term prediction by adding rainfall as a covariate to these prediction models may not be sufficient to merit investing in a forecasting system for which rainfall data are routinely processed.

  8. Novel Ice Mitigation Methods

    2008-01-01

    After the loss of Columbia, there was great concern in the Space Shuttle program for the impact of debris against the leading edges of the Orbiter wings. It was quickly recognized that, in addition to impacts by foam, ice that formed on the liquid-oxygen bellows running down the outside of the External Tank could break free during launch and hit this sensitive area. A Center Director s Discretionary Fund (CDDF) project would concentrate on novel ideas that were potentially applicable. The most successful of the new concepts for ice mitigation involved shape memory alloy materials. These materials can be bent into a given shape and, when heated, will return to their original shape.

    Sri Lanka has recently emerged from nearly three decades of protracted conflict, which came to an end five years ago in 2009. A number of researchers have explored the devastating effect the conflict has had on public health, and its impact on Sri Lanka's health system - hailed as a success story in the South Asian region. Remarkably, no attempt has been made to synthesize the findings of such studies in order to build an evidence-informed research platform. This review aims to map the 'research landscape' on the impact of conflict on health in Sri Lanka. Findings highlight health status in select groups within affected communities and unmet needs of health systems in post-conflict regions. We contend that Sri Lanka's post-conflict research landscape requires exploration of individual, community and health system resilience, to provide better evidence for health programs and interventions after 26 years of conflict.

    Turner syndrome is the most common chromosomal disorder in girls. Various phenotypic features show depending upon karyotype from normal female through ambiguous genitalia to male. Usually, Turner girls containing 45,X/46,XY mosaicism, or sex-determining region Y (SRY) gene may have mixed gonadal dysgenesis with various external sexual differentiation. We experienced a short statured 45,X Turner girl with normal external genitalia. Because SRY gene was positive, laparoscopic gonadectomy was performed. The dysgenetic gonads revealed bilateral ovotesticular tissues. The authors report a mixed gonadal dysgenesis case found in clinical 45,X Turner patient with positive SRY gene. Screening for SRY gene should be done even the karyotype is 45,X monosomy and external genitalia is normal.

    Space debris has become a growing concern in recent years, since collisions at orbital velocities can be highly damaging to functioning satellites and can also produce even more space debris in the process. Some spacecraft, like the International Space Station, are now armored to deal with this hazard but armor and mitigation measures can be prohibitively costly when trying to protect satellites or human spaceflight vehicles like the shuttle. This paper describes the current orbital debris environment, outline its main sources, and identify mitigation measures to reduce orbital debris growth by controlling these sources. We studied the literature on the topic Space Debris. We have proposed some methods to solve this problem of space debris. We have also highlighted the shortcomings of already proposed methods by space experts and we have proposed some modification in those methods. Some of them can be very effective in the process of mitigation of space debris, but some of them need some modification. Recently proposed methods by space experts are maneuver, shielding of space elevator with the foil, vaporizing or redirecting of space debris back to earth with the help of laser, use of aerogel as a protective layer, construction of large junkyards around international space station, use of electrodynamics tether & the latest method proposed is the use of nano satellites in the clearing of the space debris. Limitations of the already proposed methods are as follows: - Maneuvering can't be the final solution to our problem as it is the act of self-defence. - Shielding can't be done on the parts like solar panels and optical devices. - Vaporizing or redirecting of space debris can affect the human life on earth if it is not done in proper manner. - Aerogel has a threshold limit up to which it can bear (resist) the impact of collision. - Large junkyards can be effective only for large sized debris. In this paper we propose: A. The Use of Nano Tubes by creating a mesh

    Polymerase chain reaction (PCR) amplification of a partial fragment of the sex determining region Y (SRY) gene was used for sexing a young Linne's two-toed sloth (Choloepus didactylus), a species in which gender determination from the external genitalia is difficult. DNA was extracted from hairs of a 5-month-old sloth as well as the dam and sire as external controls. A SRY fragment (216 bases) was PCR-amplified both from the offspring and the sire, but not amplified from the dam. The DNA sequence (166 bases without primers) of the sloth PCR product was determined and compared with SRY sequences of other mammals previously reported. High homology of their nucleotide (74.1-86.8%) and deduced amino acid (63.6-85.5%) sequences indicates that the PCR product of the sloth was amplified from a region of the SRY gene, and that SRY sequences are conserved throughout mammalian orders. From the result the sex of the young sloth was determined as a male. The PCR method using hairs for sexing the sloth provides an advantageous tool for captive propagation plan in zoos. To the authors' knowledge, no report regarding SRY sequences in the order Xenarthra (Edentata) has been published.

    Destructive natural disasters such as earthquakes and tsunamis have occurred frequently in the world. For the reduction and mitigation of damages by destructive natural disasters, early detection of natural disasters and speedy and proper evacuations are indispensable. And hardware and software preparations for reduction and mitigation of natural disasters are quite important and significant. Finally, methods on restorations and revivals are necessary after natural disasters. We would like to propose natural disaster mitigation science for early detections, evacuations and restorations against destructive natural disasters. In natural disaster mitigation science, there are lots of research fields such as natural science, engineering, medical treatment, social science and literature/art etc. Especially, natural science, engineering and medical treatment are fundamental research fields for natural disaster mitigation, but social sciences such as sociology, psychology etc. are very important research fields for restorations after natural disasters. We have to progress the natural disaster mitigation science against destructive natural disaster mitigation. in the near future. We will present the details of natural disaster mitigation science.

    Full Text Available National cultural differences pose major obstacles to global business expansion. Managers, therefore, seek to learn more about cultures. Conventional managerial learning mostly draws from descriptive scientific models which have potential drawbacks such as unidimensionality, decontextualisation, and culture-level information. Explanatory models of cultural psychology can help overcome these limitations. Further, insights from a cross-culturally fluent authority provide reflective learnings. Toward this end, I engage in a conversation with Sri Sri Ravi Shankar, the founder of the Art of Living organization, on issues related to cultural identity in the global workplace in the Indian context.

    The present report provides data on the mitigation analysis of Estonia. The results for energy, forest and agricultural sectors and macro-economic analysis are given. The Government of Estonia has identified the development of energy production as the main strategical means in the movement towards market economy. Now 99% of electricity generation and about 25% of heat production in Estonia is based on oil shale combustion. To increase the efficiency of oil shale-fired power plants and decrease CO{sub 2} emissions, the State Enterprise (SE) Eesti Energia (Estonian Energy) is planning to reconstruct these power plants and introduce the Circulating Fluidized Bed (CFB) combustion technology for oil shale burning to replace the Pulverized Combustion (PC). According to the Estonian Forest Policy, two general objectives are of importance: sustainability in forestry and efficiency in forest management. For the reduction of greenhouse gases (GHG) emissions from agriculture, it is necessary to increase the efficiency of production resource usage. The growth of the GDP in 1995 was 2.9% as a result of large-scale privatization activities in Estonia and re-introduction of the available, but unused production capacities with the help of foreign and domestic investments. It is assumed that the medium growth rate of GDP reaches 6% in 1998.

  1. AGRICULTURE DISEASE MITIGATION SYSTEM

    Full Text Available Around 52% of the population of India rely on farming for their livelihood which accounts for 17% of India’s GDP. Whilst most farmers are familiar with conventional farming practices, they are often ill positioned to promptly deal with diseases and plant infestations affecting their crops. Current advisory systems tend to be generic and are not tailored to specific plots or farms. This work comprises an agriculture advisory call center similar to a modern call center to provide an agriculture disease mitigation system. The information regarding an individual farm is collected using mobile phones. The image of diseased/infected crop is also captured using mobile phones and is made available to the expert to provide the advisory. To scale the advisory, an attempt is also made to automate the disease recognition process using image processing. Unfortunately, the photos taken will be sensitive to a number of factors including camera type and lighting incident on the scene. Ideally, the images would be processed in such a way as to provide the expert with a visual representation of the affected crops that reflects the true nature of the scene. We describe a framework for standardising the colour of plant images taken using both mobile phones and compact cameras within the context of the advisory system.

    Understanding the effects of seedling density on sediment accretion, biogeochemistry and belowground biomass in mangrove systems can help explain ecological functioning and inform appropriate planting densities during restoration or climate change mitigation programs. The objectives of this study were to examine: 1) impacts of mangrove seedling density on surface sediment accretion, texture, belowground biomass and biogeochemistry, and 2) origins of the carbon (C) supplied to the mangroves in Palakuda, Puttalam Lagoon, Sri Lanka. Rhizophora mucronata propagules were planted at densities of 6.96, 3.26, 1.93 and 0.95 seedlings m−2along with an unplanted control (0 seedlings m−2). The highest seedling density generally had higher sediment accretion rates, finer sediments, higher belowground biomass, greatest number of fine roots and highest concentrations of C and nitrogen (N) (and the lowest C/N ratio). Sediment accretion rates, belowground biomass (over 1370 days), and C and N concentrations differed significantly between seedling densities. Fine roots were significantly greater compared to medium and coarse roots across all plantation densities. Sulphur and carbon stable isotopes did not vary significantly between different density treatments. Isotope signatures suggest surface sediment C (to a depth of 1 cm) is not derived predominantly from the trees, but from seagrass adjacent to the site.

    Full Text Available Background: Meteorological factors affect dengue transmission. Mechanisms of the way in which different diurnal temperatures, ranging around different mean temperatures, influence dengue transmission were published after 2011. Objective: We endeavored to determine the correlation between dengue incidence and diurnal temperature ranges (DTRs in Colombo district, Sri Lanka, and to explore the possibilities of using our findings to improve control of dengue. Design: We calculated the weekly dengue incidence in Colombo during 2005–2014, after data on all of the reported dengue patients and estimated mid-year populations were collected. We obtained daily maximum and minimum temperatures from two Colombo weather stations, averaged, and converted them into weekly data. Weekly averages of DTR versus dengue incidence graphs were plotted and correlations observed. The count of days per week with a DTR of >7.5°C and 7.5°C with an 8-week lag period, and a positive correlation between dengue incidence and a DTR<7.5°C, also with an 8-week lag. Conclusions: Large DTRs were negatively correlated with dengue transmission in Colombo district. We propose to take advantage of that in local dengue control efforts. Our results agree with previous studies on the topic and with a mathematical model of relative vectorial capacity of Aedes aegypti. Global warming and declining DTR are likely to favor a rise of dengue, and we suggest a simple method to mitigate this.

    Full Text Available Abstract Background Adolescent health needs, behaviours and expectations are unique and routine health care services are not well geared to provide these services. The purpose of this study was to explore the perceived reproductive health problems, health seeking behaviors, knowledge about available services and barriers to reach services among a group of adolescents in Sri Lanka in order to improve reproductive health service delivery. Methods This qualitative study was conducted in a semi urban setting in Sri Lanka. A convenient sample of 32 adolescents between 17–19 years of age participated in four focus group discussions. Participants were selected from four midwife areas. A pre-tested focus group guide was used for data collection. Male and female facilitators conducted discussions separately with young males and females. All tape-recorded data was fully transcribed and thematic analysis was done. Results Psychological distresses due to various reasons and problems regarding menstrual cycle and masturbation were reported as the commonest health problems. Knowledge on existing services was very poor and boys were totally unaware of youth health services available through the public health system. On reproductive Health Matters, girls mainly sought help from friends whereas boys did not want to discuss their problems with anyone. Lack of availability of services was pointed out as the most important barrier in reaching the adolescent needs. Lack of access to reproductive health knowledge was an important reason for poor self-confidence among adolescents to discuss these matters. Lack of confidentiality, youth friendliness and accessibility of available services were other barriers discussed. Adolescents were happy to accept available services through public clinics and other health infrastructure for their services rather than other organizations. A demand was made for separate youth friendly services through medical practitioners

    Full Text Available The banking sector is the backbone of the entire financial economy of a country. In today’s globalized world, most organizations use online transaction processing systems for transferring money and doing business. Natural or man-made disasters can lead to data loss which in turn can cause millions of dollars of money lost. This study focuses on disaster recovery practices in commercial banks in Sri Lanka. From our preliminary findings, it was concluded that commercial banks only have ad-hoc disaster recovery standards and practices, as there is no standard framework available. Fourteen (14 banks were selected for data collection and relevant authorities were interviewed. The results were translated as qualitative observations to understand the best practices. Similarly, international standards, compliance requirements of the central bank, and existing researches were used to develop a disaster recovery practice framework. The proposed framework was then validated for its efficiency and usefulness among commercial banks and found to be acceptable by the banking industry.  

  10. Sexuality and women's rights in armed conflict in Sri Lanka.

    Tambiah, Yasmin

    2004-05-01

    The discourse of human rights in armed conflict situations is well adapted to respond to violence and violation, invoking internationally agreed principles of civil and political rights. However, in areas where the subject or domain of rights discourse is contested or controversial, human rights advocates appear less prepared to promote and defend such rights. Sexuality is one such domain. This paper explores the complex sexual choices women in Sri Lanka have had to negotiate, particularly widows and sex workers, within a context of ethnic conflict, militarisation and war. It argues that sexuality cannot be defined exclusively in terms of violation, even in a context dominated by violence, and that the sexual ordering of society may be subverted in such conditions. Newly widowed women and sex workers have had to negotiate self-determination as well as take responsibility for earning income and heading households, in spite of contrary community pressures. For women, political and economic rights are closely linked with the ability to determine their sexual and reproductive choices. The challenge to women's and human rights advocates is how to articulate sexual autonomy as a necessary right on a par with others, and strategise to secure this right during armed conflict and postwar reconstruction.

    This study looks at the groundwater issues in the dry zone of Sri Lanka and shows how the use of remote sensing with high-resolution images can help in groundwater management. A new approach is developed for automatic extraction of the location of agro-wells using high-spatial-resolution satellite imageries. As an example, three pilot sites in three different aquifer systems in the country are considered, and their high-resolution images are analyzed over two temporal time periods. The analysis suggests that the well density in all three regions has increased over the last few years, indicating higher levels of groundwater extraction. Using the well inventory developed by this new approach, the water budgeting was prepared for the mainland of Jaffna Peninsula. The analysis shows a wide variation in well density in the Jaffna Peninsula, ranging from (as little as) less than 15 wells per square kilometer to (as high as) more than 200 wells per square kilometer. Calculations made for the maximum allowable water extraction in each administrative division of Jaffna show that less than 3 h of daily extraction per well is possible in some districts. This points to an increasing pressure on groundwater resources in the region and thus highlights the importance of understanding groundwater budgets for sustainable development of the aquifers.

    With 87.0% of its population literate, Sri Lanka occupies a high ranking position among South and South-East Asian nations in educational development. The high percentage of literacy achieved through progressive measures in education spanning half a century, however, has led to a state of complacency and less priority being given to efforts at eradicating illiteracy. This paper will focus on a recent study conducted on the incidence of illiteracy in specific disadvantaged communities in the country which indicated that in the present era of technological advancement, lack of literacy will continue to affect the life-chances of people in these communities where the rate of literacy remains much lower than the national average. The study investigates into the factors associated with illiteracy, and the attitudes and perceptions of the communities themselves towards literacy programmes and regarding the modalities and strategies of providing literacy. The implications of the study and the final recommendations drawn up in consultation with the policy makers at national and provincial levels in governmental and non-governmental sectors are also discussed in the paper.

    Full Text Available Abstract Background Rainfall data have potential use for malaria prediction. However, the relationship between rainfall and the number of malaria cases is indirect and complex. Methods The statistical relationships between monthly malaria case count data series and monthly mean rainfall series (extracted from interpolated station data over the period 1972 – 2005 in districts in Sri Lanka was explored in four analyses: cross-correlation; cross-correlation with pre-whitening; inter-annual; and seasonal inter-annual regression. Results For most districts, strong positive correlations were found for malaria time series lagging zero to three months behind rainfall, and negative correlations were found for malaria time series lagging four to nine months behind rainfall. However, analysis with pre-whitening showed that most of these correlations were spurious. Only for a few districts, weak positive (at lags zero and one or weak negative (at lags two to six correlations were found in pre-whitened series. Inter-annual analysis showed strong negative correlations between malaria and rainfall for a group of districts in the centre-west of the country. Seasonal inter-annual analysis showed that the effect of rainfall on malaria varied according to the season and geography. Conclusion Seasonally varying effects of rainfall on malaria case counts may explain weak overall cross-correlations found in pre-whitened series, and should be taken into account in malaria predictive models making use of rainfall as a covariate.

  14. Individuation, Cosmogenesis and Technology: Sri Aurobindo and Gilbert Simondon

    Full Text Available The turn of the 19th/20th centuries saw a number of philosophers of conscious evolution emerging from different cultural backgrounds. This paper argues that this phenomenon, which has sometimes been seen as a philosophical consequence of Darwin’s evolutionary theory in the life sciences, is more importantly related to the enhanced scope of human subjectivity made possible by technology at this time. Yet technology remains the “unthought within the thought” of its times, an ambiguous presence, derided for its alienating effects and praised for its enhancement of human capacities and comforts. A later generation of thinkers, belonging to the post World War II era renews the thought of conscious evolution, now in engagement with new technologies of a planet spanning scope. This essay considers the ideas of these two generations of thinkers, focusing on Sri Aurobindo (1872-1950 from the earlier generation and Gilbert Simondon (1924-1989 from the more recent era, questioning the consequences of contemporary technology in their thoughts, goals and practices. In developing the historical continuity of ideas, it tracks the question of technology from the earlier to the later generation, highlighting the understanding of both its promise and its ills and engaging with it the possibilities of conscious evolution.

    Considerable attention is being given to the availability of bodies for anatomical education. This raises the question of the manner in which they are obtained, that is, whether they are unclaimed or donated. With increasing emphasis upon the ethical desirability of using body bequests, the spotlight tends to be focused on those countries with factors that militate against donations. However, little attention has been paid to cultures where donations are readily available. One such country is Sri Lanka where the majority of the Buddhist population follows Theravada Buddhism. Within this context, the expectation is that donations will be given selflessly without expecting anything in return. This is because donation of one's body has blessings for a better outcome now and in the afterlife. The ceremonies to honor donors are outlined, including details of the "Pirith Ceremony." The relevance for other cultures of these features of body donation is discussed paying especial attention to the meaning of altruism and consent, and justification for the anonymization of cadavers. The degree to which anatomy is integrated into the surrounding culture also emerges as significant.

  18. The impact of climate mitigation on projections of future drought

    2013-06-01

    Full Text Available Drought is a cumulative event, often difficult to define and involving wide-reaching consequences for agriculture, ecosystems, water availability, and society. Understanding how the occurrence of drought may change in the future and which sources of uncertainty are dominant can inform appropriate decisions to guide drought impacts assessments. Our study considers both climate model uncertainty associated with future climate projections, and future emissions of greenhouse gases (future scenario uncertainty. Four drought indices (the Standardised Precipitation Index (SPI, Soil Moisture Anomaly (SMA, the Palmer Drought Severity Index (PDSI and the Standardised Runoff Index (SRI are calculated for the A1B and RCP2.6 future emissions scenarios using monthly model output from a 57-member perturbed parameter ensemble of climate simulations of the HadCM3C Earth System model, for the baseline period 1961–1990, and the period 2070–2099 ("the 2080s". We consider where there are statistically significant increases or decreases in the proportion of time spent in drought in the 2080s compared to the baseline. Despite the large range of uncertainty in drought projections for many regions, projections for some regions have a clear signal, with uncertainty associated with the magnitude of change rather than direction. For instance, a significant increase in time spent in drought is generally projected for the Amazon, Central America and South Africa whilst projections for northern India consistently show significant decreases in time spent in drought. Whilst the patterns of changes in future drought were similar between scenarios, climate mitigation, represented by the RCP2.6 scenario, tended to reduce future changes in drought. In general, climate mitigation reduced the area over which there was a significant increase in drought but had little impact on the area over which there was a significant decrease in time spent in drought.

    Full Text Available Problem statement: Over the last ten years there has been a phenomenal growth in the amount of funds placed in SRI globally estimated to be around US$6.5 trillion while around US$55 billion in the Australian market. Accurate knowledge of correlation of the Australian SRI market with other SRI markets overseas is crucially important for Australian (SRI investors for international portfolio diversification since portfolio diversification theory posits that the lower (higher the correlation between markets, the higher (lower the gains to be made. The study examines the relationship of the Australian SRI market with fourteen other markets-Canada, Denmark, France, Germany, Hong Kong, Ireland, Japan, Netherlands, Norway, South Africa, Sweden, Switzerland, United Kingdom and the United States. Approach: The relationships of the Australian Socially Responsible Investment (SRI market with other SRI markets worldwide during the period 1994-2009 are examined based on the dynamic conditional correlation multivariate GARCH model (DCCMVGarch. In the DCC method, the multivariate conditional variance estimation is simplified by estimating univariate GARCH models for each market. Using the transformed residuals resulting from the first stage, the authors can estimate a conditional correlation estimator. The standard errors for the first stage parameters remain while the standard errors for the correlation parameters are modified. Results: Our results showed that the Australian market experienced a surge in correlation with all other markets during the global financial crisis. During the period of study, the correlation of Australia with Canada, Denmark, Norway and the United Kingdom increased over time while its correlation with other countries remained stationary. This implies that the Australian SRI market is becoming more integrated with those of Canada, Denmark, Norway and the United Kingdom. Therefore, these overseas markets provide less

    Amphibians across the planet face the threat of population decline and extirpation caused by the disease chytridiomycosis. Despite consensus that the fungal pathogens responsible for the disease are conservation issues, strategies to mitigate their impacts in the natural world are, at best, nascent. Reducing risk associated with the movement of amphibians, non-amphibian vectors and other sources of infection remains the first line of defence and a primary objective when mitigating the threat of disease in wildlife. Amphibian-associated chytridiomycete fungi and chytridiomycosis are already widespread, though, and we therefore focus on discussing options for mitigating the threats once disease emergence has occurred in wild amphibian populations. All strategies have shortcomings that need to be overcome before implementation, including stronger efforts towards understanding and addressing ethical and legal considerations. Even if these issues can be dealt with, all currently available approaches, or those under discussion, are unlikely to yield the desired conservation outcome of disease mitigation. The decision process for establishing mitigation strategies requires integrated thinking that assesses disease mitigation options critically and embeds them within more comprehensive strategies for the conservation of amphibian populations, communities and ecosystems.

    Full Text Available Abstract Background International guidelines on research have focused on protecting research participants. Ethical Research Committee (ERC approval and informed consent are the cornerstones. Externally sponsored research requires approval through ethical review in both the host and the sponsoring country. This study aimed to determine to what extent ERC approval and informed consent procedures are documented in locally and internationally published human subject research carried out in Sri Lanka. Methods We obtained ERC approval in Sri Lanka and the United Kingdom. Theses from 1985 to 2005 available at the Postgraduate Institute of Medicine (PGIM library affiliated to the University of Colombo were scrutinised using checklists agreed in consultation with senior research collaborators. A Medline search was carried out with MeSH major and minor heading 'Sri Lanka' as the search term for international publications originating in Sri Lanka during 1999 to 2004. All research publications from CMJ during 1999 to 2005 were also scrutinized. Results Of 291 theses, 34% documented ERC approvals and 61% documented obtaining consent. From the international journal survey, 250 publications originated from Sri Lanka of which only 79 full text original research publications could be accessed electronically. Of these 38% documented ERC approval and 39% documented obtaining consent. In the Ceylon Medical Journal 36% documented ERC approval and 37% documented obtaining consent. Conclusion Only one third of the publications scrutinized recorded ERC approval and procurement of informed consent. However, there is a positive trend in documenting these ethical requirements in local postgraduate research and in the local medical journal.

    2016-03-01

    E-waste is hazardous, complex and expensive to treat in an environmentally sound manner. The management of e-waste is considered a serious challenge in both developed and developing countries and Sri Lanka is no exception. Due to significant growth in the economy and investments and other reasons the consumption of electronic and electrical equipment in Sri Lanka has increased over the years resulting in significant generation of e-waste. Several initiatives such as introduction of hazardous waste management rules, ratification of the Basel Convention in 1992 and the introduction of a National Corporate E-waste Management Program have been undertaken in Sri Lanka to manage e-waste. Strengthening policy and legislation, introducing methods for upstream reduction of e-waste, building capacity of relevant officers, awareness raising among school children and the general public and development of an e-waste information system are vital. Research on e-waste needs to be developed in Sri Lanka. The health sector could play a leading role in the provision of occupational health and safety for e-waste workers, advocacy, capacity building of relevant staff and raising awareness among the general public about e-waste. Improper e-waste management practices carried out by informal sector workers need to be addressed urgently in Sri Lanka.

  6. Examining Adaptations to Water Stress Among Farming Households in Sri Lanka's Dry Zone

    Williams, N. E.; Carrico, A.

    2016-12-01

    Climate change is increasing water scarcity in Sri Lanka's primary rice-farming zone. Whether these changes will undermine the national-level food security that Sri Lanka has worked to develop since their independence depends upon the ability of the small-scale farmers that dominate rice production and the institutions that support them to overcome the challenges presented by changing water availability. Using household survey data collected in 13 rice farming communities throughout Sri Lanka, this research explores how water stressed farmers are working to adapt to changing conditions and how the strategies they employ impact rice yields. Our analyses reveal that farmers' abilities to access irrigation infrastructure is the most important factor shaping the rice yields of water stressed Sri Lanka farmers. Notably, however, our research also identified farmers' use of hybrid, 'short duration' seed varietals to be the only climate adaptation strategy being promoted by agricultural extension services to have a significant positive impact on farmers' yields. These findings provide encouraging evidence for policies that promote plant breeding and distribution in Sri Lanka as a means to buffer the food system to climate change.

  7. Sry and SoxE genes: How they participate in mammalian sex determination and gonadal development?

    Science.gov (United States)

    She, Zhen-Yu; Yang, Wan-Xi

    2017-03-01

    In mammals, sex determination defines the differentiation of the bipotential genital ridge into either testes or ovaries. Sry, the mammalian Y-chromosomal testis-determining gene, is a master regulator of male sex determination. It acts to switch the undifferentiated genital ridge towards testis development, triggering the adoption of a male fate. Sry initiates a cascade of gene networks through the direct regulation of Sox9 expression and promotes supporting cell differentiation, Leydig cell specification, vasculature formation and testis cord development. In the absence of Sry, alternative genetic cascades, including female sex-determining genes RSPO1, Wnt4/β-catenin and Foxl2, are involved in the formation of female genitalia and the maintenance of female ovarian development. The mutual antagonisms between male and female sex-determining pathways are crucial in not just the initiation but also the maintenance of the somatic sex of the gonad throughout the organism's lifetime. Any imbalances in above sex-determining genes can cause disorders of sex development in humans and mice. In this review, we provide a detailed summary of the expression profiles, biochemical properties and developmental functions of Sry and SoxE genes in embryonic testis development and adult gonadal development. We also briefly summarize the dedicate balances between male and female sex-determining genes in mammalian sex development, with particular highlights on the molecular actions of Sry and Sox9 transcription factors.

    Chronic kidney disease (CKD) of unknown etiology (CKDu) is a serious health issue in Sri Lanka. One-to-one age and sex-matched two sample comparative study was carried out in the Medawachchiya divisional secretariat area of the North Central Province (NCP) of Sri Lanka, by randomly selecting 100 CKDu patients and 100 age and sex-matched subjects from non-CKDu affected families from the same area. An interviewer-administered questionnaire was used for the collection of data pertaining to occupation, medical history and lifestyle. Data were analyzed using a conditional linear logistic model. Working for >6 h in the field per day, exposure to sun, drinking water only from well, consumption of CKDu. Treatment of water prior to consumption had a significant protective effect against CKDu. Dehydration, history of malaria and drinking untreated well water from are likely contribute to the development of CKD of unknown etiology among the inhabitants of NCP, Sri Lanka.

    Ceramics were produced for centuries in Sri Lanka for various purposes. Ancient ceramic articles such as pottery, bricks, tiles, sewer pipes, etc, were made from naturally occurring raw materials. Use of X-ray fluorescence (XRF), X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM) in characterizing of two ancient ceramic samples from two different archaeological sites in Sri Lanka is presented. The information obtained in this manner is used to figure out the ancient ceramic technology, particularly to learn about the raw materials used, the source of raw materials, processing parameters such as firing temperature or binders used in ceramic production. This information then can be used to explore the archaeometric background such as the nature and extent of cultural and technological interaction between different periods of history in Sri Lanka.

    There is a demand to develop transplanter specifically for system of rice intensification (SRI) cultivation in Malaysia. This SRI transplanter is different from conventional transplanter as it is required special requirements for transplanting. The work focused on transplanting mechanism design which can be later attached to SRI transplanter. The mechanical design was established using linkage mechanism, having a wheel that act as timing wheel that will control the distance between transplanted seedlings. The linkage mechanism also control the opening of the flapper that allow the seedling together with its nursery soil to be dropped, and control the stopper to prevent next seedling from sliding down the tray. The use of simple mechanism will have low cost for fabrication. The design was analysed using motion analysis software. Results show the design is perfectly good and can be fabricated without any problem. The animation successfully shows the perfect movement of the mechanism and transplanting process.

    Increases in the educational level and allied factors such as late marriage have led to a decrease in the birth rate to 27.6/1000 in Sri Lanka. The World Fertility Survey in 1975 revealed that the average number of children desired was only 2.4 although the average number per family was 3.9, indicating the need for population education especially at the school level. Population education components were introduced to the junior secondary level, grades 6-9, in stages beginning in 1974 following institution of the Population Education In-School Project at the Curriculum Development Centre of the Ministry of Education. Population components were introduced into language, mathematics, science, health science, and social studies curricula already being taught. The longrange objectives of the program are to prepare future citizens who will be knowledgeable about the impact of population growth on the quality of life, and to promote responsible attitudes and decisions regarding family size. Immediate objectives are to promote understanding of population dynamics and encourage responsible attitudes. The program strives to avoid conflict with sociocultural and socioreligious norms of the various population sectors. Teacher training was provided in residential seminars, and through course guides and reference books. Reorganization of the educational structure led to a brief period of inactivity for the Population Education Unit, but work began again in 1980. The Non-Formal Education Branch of the Ministry of Education is ragarded as a possible area for introduction of population education components in adult education. Most population education programs directed toward adults are conducted by other ministries. The main problems in implementation of the junior secondary level population education program have been initial training of teachers and provision of resource and reference materials; use of the mobile library donated by the UNESCO Population Education Clearinghouse

    The valuable gems in Sri Lanka are found from the sedimentary gem deposits in Ratnapura District, which are found as alluvial deposits some are about >50 m deep. Gem bearing gravel layer is taken out from the mine, washed by panning to recover the gem minerals in the heavy mineral fraction, is a common practice in the gem mining area. Gem bearing sediment layer is associated with different heavy minerals in which different trace metals as Co, Cr, Cu, Al, Zr, Pb and As also can be present. During panning, the sediment is washed away and the heavy metals attached to the sediments are released into the environment. Hence we studied the lability and bioavailability of arsenic and other heavy metals from the gem sediments. Sediment samples were collected from 15 small scale gem mines (3 soil layers- top, gem mineral layer and layer below gem bearing gravel layer), air dried and sieved to obtain 150 mg/kg), Cu (>150 mg/kg), Pb (>400 mg/kg), Zn (>600 mg/kg) and Co ions (>100 mg/kg). Arsenite in the gem sediments were low and recorded as arsenic analysis is under investigation. Highest concentrations for bioavailable and exchangeable (leach to water) metals were Fe>Co>Zn>Mn>Ni>Cu>Pb. Sediments from few gem pits showed considerably high concentrations of metals analyzed. In some places Fe, Ni, Cu, Zn reported high in bioavailable fractions 70, 25, 20, 10 mg/kg respectively. Mobilization of these metals may increase due to changes in the pH and the presence of other ions in the environment. High concentrations of toxic metals in exchangeable and bioavailable fractions indicate the risk on plant and animals as well as the open water bodies and groundwater sources.

  14. The Energy Forum of Sri Lanka: Working toward appropriate expertise

    Science.gov (United States)

    Nieusma, Dean

    Taking my cue from the knowledge base and practices comprising appropriate technology development, and building on politics of expertise scholarship, this dissertation develops the concept of appropriate expertise: the combination of social and technical competences required to address marginalization through technological interventions. The dissertation asks what appropriate expertise looks like "on the ground" in the context of development as practiced by an exceptional group of technology designers from the Energy Forum of Sri Lanka: What design goals did they strive toward? What challenges did they face? What strategies did they employ? In an effort to answer these questions, the dissertation looks at how these designers interacted across a range of contexts with a broad spectrum of people and institutions, each with its own expertise to draw upon. In particular, it looks at how they situated their work in a highly contoured field of social power, where different types of expertise were used as resources for reinforcing or resisting existing power relations. I use the concept relations of expertise to denote the structure of expert interactions across multiple contexts of activity. Although this concept links to broad political-economic conditions that order varied expert practices, my analytic focus is at a different level: the situated experiences of expert practitioners. By starting with ground-level practices and understandings, I argue that creating new relations of expertise---that is, changing the nature of the interactions among experts and between experts and those they work with---is the key way my informants worked to legitimate marginalized perspectives and thereby empower marginalized social groups around technology-development practices. Appropriate expertise enables the creation of appropriate technologies, but it does more. It enables the creation of new relations of expertise, both through inspiring new forms of interpersonal interaction

  15. Inherited human sex reversal due to impaired nucleocytoplasmic trafficking of SRY defines a male transcriptional threshold.

    Human testis determination is initiated by SRY (sex determining region on Y chromosome). Mutations in SRY cause gonadal dysgenesis with female somatic phenotype. Two subtle variants (V60L and I90M in the high-mobility group box) define inherited alleles shared by an XY sterile daughter and fertile father. Whereas specific DNA binding and bending are unaffected in a rat embryonic pre-Sertoli cell line, the variants exhibited selective defects in nucleocytoplasmic shuttling due to impaired nuclear import (V60L; mediated by Exportin-4) or export (I90M; mediated by chromosome region maintenance 1). Decreased shuttling limits nuclear accumulation of phosphorylated (activated) SRY, in turn reducing occupancy of DNA sites regulating Sertoli-cell differentiation [the testis-specific SRY-box 9 (Sox9) enhancer]. Despite distinct patterns of biochemical and cell-biological perturbations, V60L and I90M each attenuated Sox9 expression in transient transfection assays by twofold. Such attenuation was also observed in studies of V60A, a clinical variant associated with ovotestes and hence ambiguity between divergent cell fates. This shared twofold threshold is reminiscent of autosomal syndromes of transcription-factor haploinsufficiency, including XY sex reversal associated with mutations in SOX9. Our results demonstrate that nucleocytoplasmic shuttling of SRY is necessary for robust initiation of testicular development. Although also characteristic of ungulate orthologs, such shuttling is not conserved among rodents wherein impaired nuclear export of the high-mobility group box and import-dependent phosphorylation are compensated by a microsatellite-associated transcriptional activation domain. Human sex reversal due to subtle defects in the nucleocytoplasmic shuttling of SRY suggests that its transcriptional activity lies near the edge of developmental ambiguity.

    Background and purpose: Speckle Reduction Imaging is a new algorithm that improves the image quality of B-mode scanning by reducing the reverberation artifacts. In the present study the value of this method for the characterization of atherosclerotic plaques in the internal carotid artery was investigated. Methods: Two hundred and twenty two patients (161 men, 61 women; mean age 73 years) referred for carotid ultrasound evaluation were included in the study. Patients with plaques of the internal carotid artery as identified by conventional B-mode scanning were investigated also with the addition of Speckle Reduction Imaging (SRI) with the use of a 4-11-MHz wide band linear transducer. Plaque morphology was rated according to a standardized protocol by two independent observers. Results: For the determination of plaque echogenicity, the reproducibility of SRI ({kappa} = 0.83) was higher than that of conventional B-mode ultrasound ({kappa} = 0.68). The interobserver agreement for plaque surface characterization was also higher for SRI ({kappa} = 0.8) than for conventional B-mode ({kappa} = 0.61). At the evaluation of the image quality through a semiquantitative analysis, SRI was rated superior in the plaque texture resolution, plaque borders determination, vessel wall demarcation and fibrous cap depiction. In addition, the level of 'speckle' was reduced with the use of SRI. Conclusions: SRI is a technique that shows good general agreement with high-resolution B-mode and can be used for the characterization of atherosclerotic plaques in the carotid artery. Furthermore, because this advanced technique allows reduction of ultrasound artifacts, it improves the image quality allowing more precise visualization of plaque morphological details.

    We performed a laboratory analysis of spices sold in Sri Lanka for lead content. Samples of curry powder, chili powder and turmeric powder from seven provinces, collected using the market basket survey method, underwent atomic absorption spectrometry. Blanks and standards were utilised for instrument calibration and measurement accuracy. The results were validated in two different laboratories. All samples were found to have lead levels below the US Food and Drug Administration's action level of 0.5 μg/g. Spices sold in Sri Lanka contain lead concentrations that are low and within the stipulated safety standards.

Eighty-one patients referred for liver transplantation (LT) over a period of 18 months were prospectively evaluated. Ninety-two percent (n = 74) were males. Cryptogenic cirrhosis was the leading indication for LT (58%, n = 47) followed by alcohol in 27% (n = 33). Hepatitis B and C were not seen in our cases. The liver biochemistry and clinical status of cirrhosis were similar in cryptogenic and alcoholic cirrhotics. Fourteen patients died while waiting for transplant, and nine transplants were performed. Cryptogenic cirrhosis is the leading cause for LT in Sri Lanka.

    Full Text Available There are 243 species of butterflies which including 5 families in Sri Lanka and 20 of them are endemic. However out of the 243 species 37 butterfly species belonging to 4 families was discovered from Tanthirimale Archaeological Forest area. This forest is classified as a Tropical dry mixed evergreen forests and its situated dry zone in Anuradapura district of Sri Lanka. We select three habitat types such as: forests, Rock outcrops and scrublands for studding composition and structure of butterflies in Archaeological Forest area. However, this important forest is threatened by harmful human activities such as man made fire, illegal logging, chena cultivation and road kills.

    In the rodent species Microtus cabrerae, males as well as females present several copies of the SRY gene, a single-copy gene located on the Y chromosome in most mammals. Using different PCR approaches, we have characterized the sequence, structure, and organization of the SRY copies and their flanking regions distributed on the X and Y chromosomes of this species. All copies of SRY analyzed, including those from the Y chromosome, proved to be nonfunctional pseudogenes, as they have internal stop codons. In addition, we demonstrated the association of SRY pseudogenes with different fragments of L1 and LTR retroelements in both sex chromosomes of M. cabrerae. Examining the possible origin of SRY pseudogene and retroposons association, we propose that retroposons could have been involved in the mechanism of SRY gene amplification on the Y chromosome and in the transference of the Y-linked SRY copies to the X-chromosome heterochromatin.

    When capturing imagery over long distances, atmospheric turbulence often degrades the data, especially when observation paths are close to the ground or in hot environments. These issues manifest as time-varying scintillation and warping effects that decrease the effective resolution of the sensor and reduce actionable intelligence. In recent years, several image processing approaches to turbulence mitigation have shown promise. Each of these algorithms has different computational requirements, usability demands, and degrees of independence from camera sensors. They also produce different degrees of enhancement when applied to turbulent imagery. Additionally, some of these algorithms are applicable to real-time operational scenarios while others may only be suitable for postprocessing workflows. EM Photonics has been developing image-processing-based turbulence mitigation technology since 2005. We will compare techniques from the literature with our commercially available, real-time, GPU-accelerated turbulence mitigation software. These comparisons will be made using real (not synthetic), experimentally obtained data for a variety of conditions, including varying optical hardware, imaging range, subjects, and turbulence conditions. Comparison metrics will include image quality, video latency, computational complexity, and potential for real-time operation. Additionally, we will present a technique for quantitatively comparing turbulence mitigation algorithms using real images of radial resolution targets.

    Agricultural lands occupy 37% of the earth's land surface. Agriculture accounts for 52 and 84% of global anthropogenic methane and nitrous oxide emissions. Agricultural soils may also act as a sink or source for CO2, but the net flux is small. Many agricultural practices can potentially mitigate greenhouse gas (GHG) emissions, the most prominent of which are improved cropland and grazing land management and restoration of degraded lands and cultivated organic soils. Lower, but still significant mitigation potential is provided by water and rice management, set-aside, land use change and agroforestry, livestock management and manure management. The global technical mitigation potential from agriculture (excluding fossil fuel offsets from biomass) by 2030, considering all gases, is estimated to be approximately 5500-6000Mt CO2-eq.yr-1, with economic potentials of approximately 1500-1600, 2500-2700 and 4000-4300Mt CO2-eq.yr-1 at carbon prices of up to 20, up to 50 and up to 100 US$ t CO2-eq.-1, respectively. In addition, GHG emissions could be reduced by substitution of fossil fuels for energy production by agricultural feedstocks (e.g. crop residues, dung and dedicated energy crops). The economic mitigation potential of biomass energy from agriculture is estimated to be 640, 2240 and 16 000Mt CO2-eq.yr-1 at 0-20, 0-50 and 0-100 US$ t CO2-eq.-1, respectively.

    Devil facial tumour disease (DFTD) is an infectious tumour disease and was hypothesised to be transmitted by allograft during biting based on two cytogenetic findings of DFTD tumours in 2006. It was then believed that DFTD tumours were originally from a female devil. In this study the devil sex-determining region Y (SRY) gene was PCR amplified and sequenced, and six pairs of devil SRY PCR primers were used for detection of devil SRY gene fragments in purified DFTD tumour cell lines. Using three pairs of devil SRY PCR primers, devil SRY gene sequence was detected by PCR and sequencing in genomic DNA of DFTD tumour cell lines from six male devils, but not from six female devils. Four out of six DFTD tumour cell lines from male devils contained nucleotides 288-482 of the devil SRY gene, and another two DFTD tumour cell lines contained nucleotides 381-577 and 493-708 of the gene, respectively. These results indicate that the different portions of the SRY gene in the DFTD tumours of the male devils were originally from the male hosts, rejecting the currently believed DFTD allograft transmission theory. The reasons why DFTD transmission was incorrectly defined as allograft are discussed.

  10. Microsatellite-encoded domain in rodent Sry functions as a genetic capacitor to enable the rapid evolution of biological novelty.

    The male program of therian mammals is determined by Sry, a transcription factor encoded by the Y chromosome. Specific DNA binding is mediated by a high mobility group (HMG) box. Expression of Sry in the gonadal ridge activates a Sox9-dependent gene regulatory network leading to testis formation. A subset of Sry alleles in superfamily Muroidea (order Rodentia) is remarkable for insertion of an unstable DNA microsatellite, most commonly encoding (as in mice) a CAG repeat-associated glutamine-rich domain. We provide evidence, based on an embryonic pre-Sertoli cell line, that this domain functions at a threshold length as a genetic capacitor to facilitate accumulation of variation elsewhere in the protein, including the HMG box. The glutamine-rich domain compensates for otherwise deleterious substitutions in the box and absence of nonbox phosphorylation sites to ensure occupancy of DNA target sites. Such compensation enables activation of a male transcriptional program despite perturbations to the box. Whereas human SRY requires nucleocytoplasmic shuttling and coupled phosphorylation, mouse Sry contains a defective nuclear export signal analogous to a variant human SRY associated with inherited sex reversal. We propose that the rodent glutamine-rich domain has (i) fostered accumulation of cryptic intragenic variation and (ii) enabled unmasking of such variation due to DNA replicative slippage. This model highlights genomic contingency as a source of protein novelty at the edge of developmental ambiguity and may underlie emergence of non-Sry-dependent sex determination in the radiation of Muroidea.

    Full Text Available Abstract Background SRY (sex-determining region, Y is the gene responsible of gonadal differentiation in the male and it is essential for the regular development of male genitalia. Translocations involving the human sex chromosomes are rarely reported, however here we are reporting a very rare translocation of SRY gene to the q -arm of a deleted X chromosome. This finding was confirmed by cytogenetic, fluorescent in situ hybridization (FISH and polymerase chain reaction (PCR. Case presentation A 7-month infant was clinically diagnosed as an intersex case, with a phallus, labia majora and minora, a blind vagina and a male urethra. Neither uterus nor testes was detected by Ultrasonography. G-banding of his chromosomes showed 46,X,del(X(p11 and fluorescent in situ hybridization (FISH analysis showed a very small piece from the Y chromosome translocated to the q-arm of the del(X. Polymerase chain reaction (PCR analysis revealed the presence of material from the sex-determining region Y (SRY gene. Conclusion It is suggested that the phenotype of the patient was caused by activation of the deleted X chromosome with SRY translocation, which is responsible for gonadal differentiation.

  12. Rainfall Distributions in Sri Lanka in Time and Space: An Analysis Based on Daily Rainfall Data

    T. P. Burt

    2014-09-01

    Full Text Available Daily rainfall totals are analyzed for the main agro-climatic zones of Sri Lanka for the period 1976–2006. The emphasis is on daily rainfall rather than on longer-period totals, in particular the number of daily falls exceeding given threshold totals. For one station (Mapalana, where a complete daily series is available from 1950, a longer-term perspective on changes over half a century is provided. The focus here is particularly on rainfall in March and April, given the sensitivity of agricultural decisions to early southwest monsoon rainfall at the beginning of the Yala cultivation season but other seasons are also considered, in particular the northeast monsoon. Rainfall across Sri Lanka over three decades is investigated in relation to the main atmospheric drivers known to affect climate in the region: sea surface temperatures in the Pacific and Indian Oceans, of which the former are shown to be more important. The strong influence of El Niño and La Niña phases on various aspects of the daily rainfall distribution in Sri Lanka is confirmed: positive correlations with Pacific sea-surface temperatures during the north east monsoon and negative correlations at other times. It is emphasized in the discussion that Sri Lanka must be placed in its regional context and it is important to draw on regional-scale research across the Indian subcontinent and the Bay of Bengal.

    2016-10-28

    Sex differentiation is a complex process where sexually indifferent embryo progressively acquires male or female characteristics via tightly controlled, perfectly timed, and sophisticatedly intertwined chain of events. This process is controlled and regulated by a set of specific proteins, with one of the first steps in sex differentiation being the activation of the Y-chromosomal Sry gene (sex-determining region Y) in males that acts as a switch from undifferentiated gonad somatic cells to testis development. There are several key players in this process, which constitute the Sry transcriptional network, and collective action of which governs testis determination. Although it is accepted now that many proteins engaged in signal transduction as well as regulation and control of various biological processes are intrinsically disordered (i.e., do not have unique structure and remain unstructured, or incompletely structured, under physiological conditions), the roles and profusion of intrinsic disorder in proteins involved in the male sex determination have not been accessed as of yet. The goal of this study is to cover this gap by analyzing some key players of the Sry transcriptional network. To this end, we employed a broad set of computational tools for intrinsic disorder analysis and conducted intensive literature search in order to gain information on the structural peculiarities of the Sry network-related proteins, their intrinsic disorder predispositions, and the roles of intrinsic disorder in their functions.

    Use of bottled water in Sri Lanka has increased over the last decade, while new brands of bottled water are often introduced to the market. However, the manufacturers' adherence to bottled water regulations is questionable, raising concerns regarding the quality of bottled water. The objective of the current study was to investigate the microbiological and chemical quality of bottled water in Sri Lanka. Thirty bottled water brands were sampled and their chemical and microbiological parameters were analyzed. Microbiological analysis was carried out within 1 to 3, 3 to 6, 6 to 9, and 9 to 12 mo after the date of manufacture. The results indicated that 63% of brands tested exceeded the levels permitted by the Sri Lanka Standards Institution (SLSI) for presumptive total coliforms (TC) (bottled drinking water. Throughout their shelf life, the counts of TC, FC, and HPC bacteria decreased. Bacteria identified were Klebsiella pneumoniae ssp. pneumoniae, Enterobacter cloacae, Pseudomonas aeruginosa, and Pasteurella haemolytica, the most frequently being P. aeruginosa. The dominant fungi identified were Aspergillus sp. and Penicillium sp. Inorganic chemical parameters were within permitted levels for all brands except for initial content of ammonia. The results of this study show the need for the bottling industry to be monitored closely by relevant authorities, in order to provide safe bottled drinking water to consumers in Sri Lanka.

    Full Text Available             Enhancement of carbon storage through the establishment of man-made forests has been considered as a mitigation option to reduce increasing atmospheric CO2 levels. Therefore the present study was carried out to estimate the biomass and carbon storages of the main stem of Eucalyptus grandis using allometric relationships using the plantations of Nuwara Eliya and Badulla districts in Sri Lanka. Tree diameter and total height were measured for the samples trees and stem volume was estimated using a previously built individual model for the same species. Stem biomass was estimated using core samples and carbon was determined using Walkley-Black method. Finally the biomass values were converted separately to the carbon values. Non-liner regression analysis was employed for the construction of models which had age as the explanatory variable. Linear regression was used in order to build the models to predict the above ground and stem biomass and carbon using volume as the explanatory variable. For both linear and non-linear types, the model quality was tested using R2 and fitted line plots. According to the results, stem biomass and carbon values at the 7th year were 110.8 kg and 68.7 kg respectively. Stem biomass and carbon values at the 40th year were 1,095.8 kg and 679.4 kg respectively. Carbon content at the age 20 was 62.0% from the stem biomass. Exponential models were proven to be better than the logistic models to predict the diameter, height, stem volume, biomass and carbon with age. R2 values and the fitted line plots indicated that the selected models are of high quality. Linear models built to predict the stem biomass and carbon using stem volume also showed the high accuracy of these models which had R2 values above 97.9%.

    2008-01-01

    NASA s plans for implementing the Vision for Space Exploration include returning to the moon as a stepping stone for further exploration of Mars, and beyond. Dust on the lunar surface has a ubiquitous presence which must be explicitly addressed during upcoming human lunar exploration missions. While the operational challenges attributable to dust during the Apollo missions did not prove critical, the comparatively long duration of impending missions presents a different challenge. Near term plans to revisit the moon places a primary emphasis on characterization and mitigation of lunar dust. Comprised of regolith particles ranging in size from tens of nanometers to microns, lunar dust is a manifestation of the complex interaction of the lunar soil with multiple mechanical, electrical, and gravitational effects. The environmental and anthropogenic factors effecting the perturbation, transport, and deposition of lunar dust must be studied in order to mitigate it s potentially harmful effects on exploration systems. This paper presents the current perspective and implementation of dust knowledge management and integration, and mitigation technology development activities within NASA s Exploration Technology Development Program. This work is presented within the context of the Constellation Program s Integrated Lunar Dust Management Strategy. The Lunar Dust Mitigation Technology Development project has been implemented within the ETDP. Project scope and plans will be presented, along with a a perspective on lessons learned from Apollo and forensics engineering studies of Apollo hardware. This paper further outlines the scientific basis for lunar dust behavior, it s characteristics and potential effects, and surveys several potential strategies for its control and mitigation both for lunar surface operations and within the working volumes of a lunar outpost.

    Abstract Background: Highly hazardous organophosphorus (OP) insecticides are responsible for most pesticide poisoning deaths. As they are removed from agricultural practice, they are often replaced by carbamate insecticides of perceived lower toxicity. However, relatively little is known about poisoning with these insecticides. Methods: We prospectively studied 1288 patients self-poisoned with carbamate insecticides admitted to six Sri Lankan hospitals. Clinical outcomes were recorded for each patient and plasma carbamate concentration measured in a sample to confirm the carbamate ingested. Findings: Patients had ingested 3% carbofuran powder (719), carbosulfan EC25 liquid (25% w/v, 389), or fenobucarb EC50 liquid (50% w/v, 127) formulations, carbamate insecticides of WHO Toxicity Classes Ib, II, and II, respectively. Intubation and ventilation was required for 183 (14.2%) patients while 71 (5.5%) died. Compared with carbofuran, poisoning with carbosulfan or fenobucarb was associated with significantly higher risk of death [carbofuran 2.2%; carbosulfan 11.1%, OR 5.5 (95% CI 3.0–9.8); fenobucarb 6.3%, OR 3.0 (1.2–7.1)] and intubation [carbofuran 6.1%; carbosulfan 27.0%, OR 5.7 (3.9–8.3); fenobucarb 18.9%, OR 3.6 (2.1–6.1)]. The clinical presentation and cause of death did not differ markedly between carbamates. Median time to death was similar: carbofuran 42.3 h (IQR 5.5–67.3), carbosulfan 21.3 h (11.5–71.3), and fenobucarb 25.3 h (17.3–72.1) (p = 0.99); no patients showed delayed onset of toxicity akin to the intermediate syndrome seen after OP insecticide poisoning. For survivors, median duration of intubation was 67.8 h (IQR 27.5–118.8) with no difference in duration between carbamates. Reduced GCS at presentation was associated with worse outcome although some patients with carbosulfan died after presentation with normal GCS. Conclusions: We did not find carbamate insecticide self-poisoning to vary markedly according to the carbamate
