Summary: This study utilized multivariate statistical methods to determine the origin of arsenic and trace element anomalies through the analysis of hydrochemical results. Arsenic is primarily derived from the dissolution of local rocks and sediments, with the presence of volcanic mountains and igneous rocks being major contributing factors to the arsenic anomaly. Additionally, certain samples with arsenic anomalies may be attributed to anthropogenic factors such as pesticide use.

Summary: The establishment of protected areas and buffer zones is widely used to mitigate biodiversity loss, but the ecological outcomes of buffer zones have been rarely measured. A study in Nepal's Terai Arc Landscape found that both the national park and the buffer zone had positive effects on multiple species, but the effectiveness varied depending on the species group and threats they faced.

Summary: The occurrence of arsenic in groundwater and its accumulation in rice grains is a global health concern. This study found that utilizing alternate wetting and drying (AWD) irrigation with temporarily stored groundwater (TSG) can effectively reduce arsenic content in rice grains. The research also highlights the importance of irrigation management and rice variety selection in minimizing arsenic accumulation in rice grains.

Summary: This study evaluates the prevalence of pollutant sediment traps in nearshore aquifers adjacent to large lakes and focuses on the enrichment, transport, and release of arsenic. Field data from six sites along the Laurentian Great Lakes indicate widespread enrichment of arsenic in oxic nearshore aquifers, while arsenic is more mobile in reducing aquifers.

Summary: This study predicted and mapped the soil organic carbon content in the topsoil of the Sarlahi district in Nepal, comparing the performance of different techniques and identifying silt deposition from river systems as a key predictor for SOC content. Random Forest technique outperformed Stepwise-Multiple-Linear-Regression-Kriging in predicting SOC, indicating the importance of silt deposition in low-relief alluvial regions.

Summary: This study examined the risk factors of preterm birth (PTB) in Southeastern Terai, Nepal. The results showed that maternal socio-demographic factors, birth order, and dietary factors were associated with PTB. Therefore, these factors should be considered when designing targeted health interventions in Nepal.

Summary: Forest fires have significant ecological effects on vegetation patterns. This study investigates the biomass loss of woody plant seedlings caused by fire and its impacts on the demographic structure of plants in Terai forests of Nepal. The results show that fire leads to a high density of resprouting and newly grown seedlings, while also negatively affecting the biomass and demographic structure of woody plants.

Summary: This article reports on a porous chelating resin for the removal of arsenic ions from water. The resin achieved a high arsenic uptake capacity under varying experimental conditions. The theoretical results showed Langmuir adsorption capacities of 3.27 mg g-1 and 1.13 mg g-1 for As(V) and As(III) respectively. The adsorption kinetics followed a pseudo-second-order model.

Summary: The utilization and development of land resources affect groundwater quality. Land use has complex relationships with groundwater chemical composition, which are influenced by the buffer zone scale. Cropland has the greatest impact on groundwater hydrochemistry in the city, while the transformation of saline-alkaline land to cropland inhibits salt accumulation. Analysis and principal component analysis emphasize the deterioration of groundwater quality due to agricultural pollution.

Summary: Anoxic storage containers can enhance arsenic removal in groundwater treatment systems, even when the oxidation process is slower compared to aerobic storage. Aeration prior to storage may lead to rapid oxidation of Fe2+ and impact the removal efficiency of As.

Summary: The hispid hare, listed as an endangered species globally and nationally, is facing continuous decline due to human activities. This study aimed to identify its current distribution pattern, habitat factors, and conservation threats in Shuklaphanta National Park, Nepal. A survey was conducted, and habitat predictors were measured. The study found a clumped distribution pattern of the hispid hare and identified several severe threats. The findings will guide conservation efforts and serve as a baseline for future research.

Summary: Globally, 17.2% of irrigated harvested area is in arsenic hazard areas, contributing 19.7% of total irrigated crop production. More than 25% of rice, wheat, and maize consumed in South Asian countries originate from arsenic hazard areas, with international trade also playing a role in distributing arsenic risk.

Summary: In this study, the pitch robustness of the PNCC feature for children's speech recognition is analyzed, and a pitch-normalized PN-PNCC feature is proposed to improve the pitch variation effect on PNCC while maintaining noise suppression capability. The effectiveness of PN-PNCC feature is investigated using recurrent structures like GRU and LiGRU, showing performance improvement in adult and children speech recognition under clean and noisy conditions.
