Summary: The study explores energy poverty in Sri Lanka using the Multidimensional Energy Poverty Index (MEPI), finding that households in Sri Lanka are experiencing a moderate level of energy poverty on average, with the lack of access to modern cooking fuel being the largest contributor. Significant differences in energy poverty were observed by gender, age, ethnicity, income group, and sub-national location of the household.

Summary: The study examined the influence of rapid regional development on trace elements accumulation in the sediments of Batticaloa lagoon, Sri Lanka. It was found that the sediment cores had low pollution levels and ecological risk, suggesting the need for environmental management planning to ensure sustainable development in the rapidly developing region.

Summary: Groundwater, stream water, and stream sediment samples were collected from a coal mine area in Dazhu, Southwestern China to study the effects of coal mine pollution. The water samples had a slightly acidic to alkaline pH, and the dominant ions were Ca2+ + Mg2+-HCO3- and Ca2+ + Mg2+-Cl-. However, the concentrations of Mn and Fe in the water exceeded the standard values. Principal component analysis revealed that the metal concentration in stream sediments was influenced by the coal mine drainage.

Summary: This study found that TBT concentrations varied in coastal water and sediment, with the highest levels found in Colombo port. Additionally, a positive correlation was observed between TBT levels in Perna viridis and body weight. The presence of TBT may lead to reproductive impairment in aquatic animals.

Summary: Through histopathology and phylogenetic analysis, we identified multiple distinct trematode species causing ocular infections in children in Sri Lanka. Collaboration between clinicians and parasitologists, as well as community awareness of water contamination hazards, is crucial for the diagnosis, control, and prevention of such infections.

Summary: This paper examines the impact of monetary policy shocks on Sri Lanka's economy during and after the ethnic conflict, focusing on the strength of the credit and exchange rate channels. Using a VAR model for the period of 2003-2019, the study finds that monetary policy shocks have a significant and persistent effect on key macroeconomic variables, although some puzzling results emerge. Furthermore, the effects of these shocks are more pronounced and lasting in the post-conflict period, and a tight monetary policy effectively controls inflation during this period. The interest rate and exchange rate channels play a dominant role in the post-conflict period, while the credit channel shows some lagged response.

Summary: This study aims to assess the extent of SDG disclosures in annual reports of companies in Sri Lanka and identify the reasons affecting such disclosures. The results show that SDG 9 and SDG 17 are the most disclosed SDGs, but the overall level of disclosure remains low. Interviews suggest that companies primarily use SDG disclosures to enhance their legitimacy rather than actively adjusting their operations to integrate SDGs.

Summary: This study used EOF and harmonic analysis to analyze rainfall variation in Sri Lanka. The results showed strong annual and semi-annual variation in the northeastern and southwestern parts of the country, respectively. Harmonic analysis successfully identified seven well-defined rainfall regime characteristics.

Summary: Negombo Lagoon in Sri Lanka has great socioeconomic value but has undergone two major changes in the past 160 years. The first change occurred in the mid-19th century when the source of organic material switched from terrestrial to marine after the construction of the Hamilton Canal. The second change occurred post-1940s during Sri Lanka's industrialization period, leading to high anthropogenic inputs in the estuary.

Summary: This large case-control study examined the association between domestic violence (DV) and self-poisoning in Sri Lanka. The results showed that exposure to at least one type of DV within the previous 12 months was strongly associated with self-poisoning for both men and women. Women were most strongly associated with physical violence, while emotional abuse showed the highest risk for men. The study also found that 38% of self-poisoning cases in women and 22% in men could be attributed to DV.

Summary: The hydro-geochemistry of drinking water in CKDu endemic and non-endemic areas in Sri Lanka was analyzed to identify potential risk factors for CKDu. The study found that the fluoride levels in groundwater exceeded the permissible level in CKDu locations. In conclusion, this study highlights the water quality status of CKDu and non-CKDu areas and emphasizes the potential health risks associated with the consumption of poor quality water.

Summary: There are seven brands of veterinary rabies vaccines available in Sri Lanka, but there is no established procedure for testing their potency prior to release. This study aimed to test the potency of these vaccines using a mouse challenge test in collaboration with a reference laboratory in France. Out of the eight tested vaccines, four were compliant with the potency requirements, while three were not and one had an unvalidated potency value. It is important to test the vaccines' potency before market release to ensure good immunization in pre-exposure vaccination programs.

Summary: Sri Lanka has successfully eliminated lymphatic filariasis as a public health concern, but recent infections with subperiodic filarial species suggestive of zoonotic infections have been found in dogs across the country. Limited information on the prevalence, diversity, and predictors of filarial infections in dogs has resulted in suboptimal control and prevention of these parasites.

Summary: This study characterizes lignite samples from Kapurdi, Giral, and Sonari mines in Rajasthan's Barmer Basin using petrographic and geochemical techniques. The results provide insights into the geochemical properties, hydrocarbon potential, depositional environment, and paleo-climatic conditions of these lignite deposits. The study finds high volatile matter and sulfur concentrations in the Barmer lignite deposits, as well as indications of a wet environment during organic material decomposition. The findings have implications for understanding the coalification profile and hydrocarbon source rock potential in the region.

Summary: The assessment of heavy metal concentrations in agricultural soil is important for crop safety and quality, as well as potential risks to human health. This review analyzed published data on seven heavy metals in Iranian farmland soils and found that nickel and cadmium exceeded permissible levels. Arsenic showed significant contamination in multiple provinces, while lead and cadmium were highly contaminated in Fars province. Overall, the contamination levels of heavy metals in Iranian agricultural soils were relatively low.

Summary: This study analyzed apatite grains from the Angico dos Dias Carbonatite Complex region in Brazil using an electron probe microanalyzer. The results showed that the apatite grains had characteristics of metacarbonatitic lithotypes and some had undergone substitution processes. Statistical analysis helped identify the sources of the apatite grains and confirmed the presence of carbonatitic bodies in the area.
