Article Synopsis
- Rapid population growth and industrialization in urban areas are significantly degrading water quality, particularly in the Doon Valley region of the Garhwal Himalaya.
- Groundwater samples were tested for six toxic elements, with results indicating that although the levels were below safe limits, molybdenum and nickel were the most concentrated elements detected.
- Machine learning models, especially the radial basis function neural network, showed strong accuracy in predicting various water quality indices related to heavy metals, although the multilayer perceptron model exhibited more variability in its predictions.
Article Synopsis
- Stress is a common issue among college students, significantly affecting their mental health and academic performance, leading to the need for better understanding and interventions.
- A study conducted on 160 undergraduate students at St. John's College in Agra, India, found that 64.4% experienced moderate stress, with higher stress reported among female and urban students.
- The research highlights the urgent need for targeted stress management programs and further investigation into the causes of stress among students.
Aim: Silver diamine fluoride (SDF) is taken into account as one among the effective measures for caries arrest and prevention in youngsters, due to the fact it proffers marginally invasive but cost-effective alternative to time-commemorated restorative caries control. The study was carried out to appraise the effectiveness of SDF (38%) in arresting active carious lesions and to gauge parental perception toward the treatment of cavities with SDF in the primary teeth.
Materials And Methods: A total of 36 children in the age range 2-10 years, having active caries lésions, based on ICDAS criteria, in primary teeth were selected following the baseline examination.
Background: The lack of interoperability is one of the biggest obstacles to the complete digitalization of patient health information in electronic medical records (EMR). The high volume of data breaches has put pressure on care providers to adopt data protection measures to remain compliant with legal requirements. Extreme data protection measures can impede information flow, but they also instill confidence in secure information sharing.

We introduce a novel self-standing, nanoporous carbon scaffold (NCS, 25 μm thick), with an ordered inverse opal pore structure (∼85 nm pore) as a microporous layer (MPL) in a polymer electrolyte membrane fuel cell. Unlike previous studies, through chemical functionalization of the pore surfaces, the wettability of the MPL is controllably modified without altering the pore structure. environmental scanning electron microscopy experiments revealed water sorption in the hydrophilic NCS under moderate relative humidity (RH) conditions but not in the hydrophobic NCS, wherein water condensation on the surface was noted only at high RH.
