Life cycle assessment of hydrothermal carbonization of municipal solid waste for waste-to-energy generation.

Municipal solid waste (MSW) management is a major concern for Bangladesh, given its high population density and increasing waste production rate. Conventional waste management methods, such as landfilling, result in high carbon emissions for the environment. With over 70% of MSW being organic, hydrothermal carbonization (HTC) has emerged as a promising technology for recovering energy and nutrients from such heterogeneous waste streams.

Regional influence on the aesthetic preference of different Mongolian profiles: A comparative study of assessors from Northeast and Mainland India.

Objective: The purpose of this study was to determine the aesthetic preferences of three different groups-layperson, dentists, and orthodontists, with different ethnic and geographical backgrounds from North-eastern and Mainland India, and to evaluate whether there is any difference in the perception of facial profile aesthetics. The influence of one's ethnic and regional origin in the perception of facial profile aesthetics was evaluated in two populations of different backgrounds using VAS scale.

Materials And Methods: Facial profile photos of 2 Mongolian descendants, 1 man and 1 woman having Class I (normal) profile were digitized and modified, sagittally, to obtain 7 sagittal variations of each profile.

Impact of facial components on the attractiveness of face: A perception-based study.

Introduction: Magazines and television displays are not merely crammed with faces-they are filled with appealing faces, and both men and women are interested in a suitable partner's appearance. This study investigated what makes a face attractive and whether perception-related differences exist between facial attractiveness and facial components.

Methods: In this descriptive-analytical study, frontal and lateral view photographs of 18 young adults (9 male and 9 female) in Class I, II, and III malocclusions were assessed by 90 orthodontists, dentists, models, and laypeople using a 7-point Likert scale in terms of attractiveness.

Bendable Electro-chemical Lactate Sensor Printed with Silver Nano-particles.

Here we report a flexible amperometric lactate biosensor using silver nanoparticle based conductive electrode. Mechanically bendable cross-serpentine-shaped silver electrode is generated on flexible substrate for the mechanical durability such as bending. The biosensor is designed and fabricated by modifying silver electrode with lactate oxidase immobilized by bovine serum albumin.
