Assessment of particulate matter and particle path trajectory analysis using a HYSPLIT model over Dire Dawa, Ethiopia
- 2024
This work deals with the assessment of particulate matter (PM1, PM2.5, and PM10) over Dire Dawa during the month of May 2021. In the study, purple sensor (PS) and gravimetric methods (GM) were used. The purple sensor was to provide real-time measurements of PM1.0, PM2.5, and PM10 particulates. The GM instruments were constructed using wood with 1 m height (distance to ground), with flat board on t......
Cellulose based adsorbent for cationic methylene blue dye removalAbstract New chemically amended (sodium periodate cellulose nanoparticle (NaIO4 -CNP) adsorbent material was synthesized from dried fibers of cotton. The synthesized NaIO4 -CNP adsorbent material was characterized for functional groups, crystallite size, surface morphology, morphological structure, and particle size) by using ... ...

Prediction of debris flow initiation points using high resolution DEM and GIS analysis in South Korea Abstract This study presents a GIS analysis model that utilizes high-resolution Digital Elevation Map data to predict the initiation points of debris flow through the overlap of slope stability analysis techniques and rainfall flow analysis. The debris flow that occurred on Mount Woomyun in Seoul, South Korea in 2011 was selected as the case study for comparing and ... ...
Entropy generation on MHD motion of hybrid nanofluid with porous medium in presence of thermo-radiation and ohmic viscous dissipation Abstract Hybrid nanotechnology has significantly contributed to enhancing energy efficiency and reducing heat loss. This study addresses entropy analysis in the motion of hybrid nanofluids incorporating magnetohydrodynamic effects, thermal radiation, and ohmic viscous dissipation phenomena. The implementation of magnetohydrodynamic, thermal radiation, and dissipatio... ...
Heterogeneous catalytic conversion of lignocellulose: towards green and renewable chemicals Abstract The world's nations are searching for renewable and sustainable energy and fuels due to restrictions on carbon discharges and fossil feedstock shortage.. Biomass is a renewable and sustainable resource; and its conversion is one of the research hotspot areas. This review aims to summarize the evidence gained from different methods of converting lignocellulo... ...
Non-sample fuzzy based convolutional neural network model for noise artifact in biomedical images Abstract The use of a light-weight deep learning Convolutional Neural Network (CNN) augmented with the power of Fuzzy Non-Sample Shearlet Transformation (FNSST) has successfully solved the problem of reducing noise and artifacts in Low-Dose Computed Tomography (LDCT) pictures. Both the Normal-Dose Computed Tomography (NDCT) and the Low-Dose Computed Tomography (LDCT... ...
A fundamental concept for linking methods, system models, and specific models Abstract In the field of model-based development, and especially model-based systems engineering, the efficient and effective use of system models and specific models is of great interest. However, models strongly depend on the method they are linked to. Methods require models as input and associated models that are part of the method itself. Subsequent, methods are... ...
Detection of six potato viruses using double antibody sandwich ELISA from in vitro, screen house and field grown potato crops in EthiopiaAbstract Virus infection in seed potato reduces yield, and the problem is exacerbated when an early-generation seed is affected. The prevalence of six key potato viruses, PVY, PVX, PLRV, PVA, PVS, and PVM, was assessed among decentralized seed multipliers such as individuals, farmer seed group cooperatives, private companies, and agricultural research centers that p... ...
