Sustainable material selection for medical equipment through life cycle assessment and multi-objective optimizationNARA Subscribed
Material selection for medical equipment manufacturing requires balancing environmental sustainability, economic feasibility, and energy consumption. Despite increased focus on sustainability, few studies have integrated multi-objective optimization frameworks to simultaneously evaluate these factors. This study applies Life Cycle Assessment (LCA) with the ReCiPe endpoint method and uses Multi-Objective Genetic Algorithm (MOGA...
The demand for plastic has led to a large increase in plastic waste. Converting that waste into hydrogen offers environmental benefits. To promote more sustainable practices, it is essential to use life cycle assessment (LCA) to evaluate the environmental impacts of hydrogen production and transportation. This study provides a comparative LCA of six different pathways for hydrogen production and transportation. Two main hydrog...
Wind dispersed tree species have greater maximum heightNARA Subscribed
Aim We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal. Location Americas, Africa and the Asia‐Pacific. Time period 1970–2020. Major taxa studied Gymnosperms and Angiosperms. Methods We used a dataset consisting of tree inventories from 2821 plots across three biogeographic regions (Americas, Africa and Asia‐Pacific),...
Here is presented a study to investigate the geographic variation in rice grain nutrients (trace and macro-elements and vitamins) and toxicants (arsenic species and cadmium) across a contiguous strip of 36 districts that constitute western Bangladesh. The survey collected ~ 500 market rice samples, averaging 15 samples and 10.7 cultivars per district. New LC-MS methods were developed for rice relevant, B and E complex compound...
Recycled Household Ash in Rice Paddies of Bangladesh for Sustainable Production of Rice Without Altering Grain Arsenic and CadmiumNARA Subscribed
In Bangladesh most agronomic biomass (straw, husk, dried dung) is burnt for domestic cooking use. Consequently, the soil is continuously stripped of mineral nutrients and carbon (C) substrate. Here we investigate if recycling of household ash (ash) as fertilizer can sustainably improve soil fertility as well as minimise accumulation of toxic elements (As, Cd) in rice grain. Large scale field trials across two geographic region...
