Emerging renal biomarkers (e.g., kidney injury molecule-1 (KIM-1) and neutrophil gelatinaseassociated lipocalin (NGAL)) are thought to be highly sensitive in diagnosing renal injury. However, global data on reference intervals for emerging biomarkers in younger populations are lacking. Here, we aimed to determine reference intervals for KIM-1 and NGAL across a pediatric population in Sri Lanka; a country significantly impacted by the emergence of chronic kidney disease of unexplained etiology (CKDu). Urine samples were collected from children (10-18 years) with no prior record of renal diseases from the dry climatic zone of Sri Lanka (N = 909). Urinary KIM-1 and NGAL concentrations were determined using the enzyme-linked immunosorbent assay (ELISA) and adjusted to urinary creatinine. Biomarker levels were stratified by age and gender, and reference intervals derived with quantile regression (2.5th, 50th, and 97.5th quantiles) were expressed at 95% CI. The range of median reference intervals for urinary KIM-1 and NGAL in children were 0.081-0.426 ng/mg Cr, 2.966-4.850 ng/mg Cr for males, and 0.0780-0.5076 ng/mg Cr, 2.0850-3.4960 ng/mg Cr for females, respectively. Renal biomarkers showed weak correlations with age, gender, ACR, and BMI. Our findings provide reference intervals to facilitate screening to detect early renal damage, especially in rural communities that are impacted by CKDu. [ABSTRACT FROM AUTHOR]

Irrigation Water Management (IWM) being considered essential as it contributes to crop production all over the world. Nonetheless, water losses throughout the system, inefficient irrigation practices and lack of attention towards the proper maintenance of existing infrastructure were the constraining factors to achieve the benefits of sustainable use of water. Hence, this paper develops strategies to achieve sustainable water management of irrigation systems. Sixteen semi-structured interviews were conducted for industry professionals in the IWM sector in Sri Lanka as the main data collection method in this study. The collected data were analysed using a code-based content analysis based on the directed approach. The research findings identified four main categories of strategies, namely, engineering, management, operational and regulatory. The findings are substantially beneficial for industry practitioners in the water management sector to overcome the issues in IWM practices regarding the water use efficiency, equity of water distribution, environmental integrity and economic acceptability. This study can be further extended to prioritise the issues and strategies to statistically generalise the findings. [ABSTRACT FROM AUTHOR]

We determined the genetic diversity of the Green Turtle Chelonia mydas (Linneaus, 1758) nesting at Kosgoda rookery, the second largest sea turtle aggregation on the southwestern coast of Sri Lanka. Skin tissue samples were collected from 68 nesting females and genetic diversity was estimated using six microsatellite loci. High genetic diversity was observed within the population as all loci analyzed were highly polymorphic with a total of 149 alleles observed. The mean number of alleles per locus was 24.7 and the mean observed and expected heterozygosity across all loci were 0.75 and 0.93, respectively. It appears that five out of six loci were not in Hardy-Weinberg equilibrium, while micro-checker analysis suggested that the Kosgoda Green Turtle population was possibly in equilibrium. The viability of a population is unlikely to be reduced if high genetic diversity is maintained within it. Although the Green Turtle population nesting at Kosgoda is small compared to other nesting rookeries in the world, the high genetic diversity observed suggests that the population may not be undergoing a bottleneck.

Purpose Delays represent one of the most critical factors that affect the cost of a construction project. They have to be therefore analysed comprehensively using appropriate techniques. The purpose of this paper is to find out the delay analysis techniques (DATs) that are most commonly used in road projects in Sri Lanka, the extent of their usage, the criteria that can be used in selecting them and the technique that is most appropriate for the selection.Design/methodology/approach The research methodology adopted included an extensive literature review, expert interviews and a questionnaire survey.Findings In road projects in Sri Lanka, five types of DATs are mainly used. The “As-planned v. As-built Analysis” technique is the most commonly used technique while “Window Analysis” is the least used technique. Out of the nine criteria identified for selecting a DAT, the most important criterion is the acceptability of the technique to courts and tribunals. “Window Analysis” was found to be the most appropriate DAT that can be used in road construction projects in Sri Lanka.Originality/value “Window Analysis” can be recommended as the most appropriate DAT for road projects in Sri Lanka.

The contribution of local communities has become widely recognized as a better alternative in forest management than the traditional command-based control approach. However, several years later of implementation, most programs were failed due to a lack of community participation, imposing an uncertain future for community forestry. This paper examines rural Sri Lankans' participation intention in community forestry (CF) program by using the Probit regression model. Randomly selected 300 individuals representing both CF members and non-CF members were interviewed for the study. The study results indicate that rural residents' intention in future CF program negatively correlated with the participation status (CF membership) of individuals. Accordingly, CF members show less participation intention in future CF program than non-CF members. Socio-economic variables such as education level (p < 0.01) and the occupation of head of the household (p < 0.05) and total household income (p < 0.01) have significant influences on individuals' participation intention in CF. In addition, non-monetary benefits derived from CF and perception on the product regulation and conflict mitigation are also appeared to significantly and positively affect villagers' intention. The findings also revealed the knowledge gap on the purpose of the CF program and CF policy design. Hence, require immediate attention to improve awareness. Moreover, failure to raise local people's participation intention in CF may indicate inadequate or ineffective government policies. Therefore, the Department of Forest Conservation should take sound measures to ensure that community-based forest management policies are consistently implemented at different administrative levels across the country and its rightness should be evaluated strictly.
