Assessment of particulate matter and particle path trajectory analysis using a HYSPLIT model over Dire Dawa, Ethiopia
- 2024
Teshager Argaw Endale, Gelana Amente Raba, Kassahun Ture Beketie, Gudina Legese Feyisa, Haftu Brhane Gebremichael
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...... hiện toàn bộ
Cellulose based adsorbent for cationic methylene blue dye removal
Tập 6 Số 2
Hana Melese, Hizkeal Tsade
AbstractNew 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 ...... hiện toàn bộ
Preparation of some selective glass–ceramics from nano-silica within the Li2O–SiO2 system with ZrO2 for future dental applications
F.H. ElBatal, M. A. Marzouk, M. A. Azooz, H.A. ElBatal
AbstractMany recent studies have indicated that some modified silicate glass–ceramics are considered and recommended to be part of the process of dental applications. Examples from the recommended glass–ceramics include modified lithium silicate with various dopants (ZrO2, CeO2), mica-based glass–ceramics, and leucite-based...... hiện toàn bộ
Application of Ultrasound Image Velocimetry (UIV) to cohesive sediment (fluid mud) flows
Tập 6 Số 3
Bart Brouwers, Jeroen van Beeck, Evert Lataire
AbstractUltrasound image velocimetry (UIV) is a technique that enables non-intrusive whole-flow field velocimetry measurements in opaque fluids. It gained interest in experimental fluid dynamics to study the flow mechanics of, amongst others, sediment-laden fluids. Further customisation of this technique is required to make it a reliable asset for experimental rese...... hiện toàn bộ
Multi-parameters approach to assessment of soil liquefaction vulnerability in wetland areas of Lagos, Southwestern, Nigeria
H. T. Oladunjoye, K. S. Ishola, K. F. Oyedele, L. Adeoti
AbstractWith respect to geology, most coastal terrains are underlain by problematic soils, some of which are liquefiable in nature and may cause sudden failure of engineering infrastructures. Against this background, this study was carried out to investigate the subsurface geology of some Lagos coastal areas and their engineering implications using geophysical and ...... hiện toàn bộ
Assembly and characterization of the complete mitochondrial genome of Descurainia sophia: a medical plant producing glucosinolate
Tập 6 Số 3
Ling Zhao, Yan H, Yuyan Zhu, Haoyu Jia, Yan-Feng Han, Xiaoke Zheng, Min Wang, Weisheng Feng
AbstractAs a commonly used traditional Chinese medicine, Descurainia sophia has various reported pharmacological activities such as prevention of chronic diseases, cardiovascular protection, neuroprotection, anticancer, antioxidant, and has high nutritional values, but its mitochondrial genome (mitogenome) has not been reported. In this s...... hiện toàn bộ
Antimicrobial activities of essential oils from three species of citrus fruits against six infectious tropical bacteria: implications for the care and control of common bacterial tropical diseases in developing countries
Ayomadewa Mercy Olatunya, Oladele Simeon Olatunya, Gul Hassan, Lateef A. Adeyemi, Oyeku Akibu Oyelami, E. T. Akintayo
AbstractThe burden of bacterial infections and the failure of antimicrobial agents are increasing worldwide, especially in sub-Saharan Africa. This raises the need for novel therapeutic agents to combat bacterial infectious diseases. The sensitivity of several common pathogenic bacteria to essential oils from the peels of three species of citrus plants was investig...... hiện toàn bộ

Assessment of alternative methods for analysing maximum rainfall spatial data based on generalized extreme value distribution
Thales Rangel Ferreira, Gilberto Rodrigues Liska, Luiz Alberto Beijo
AbstractThe present study aimed to analyze and spatially model maximum rainfall in the southern and southwestern regions of Minas Gerais using spatial statistical methods. Daily data on maximum rainfall were collected from 29 cities in the region. To obtain predictions of maximum rainfall for return periods of 2, 5, 10, 50, and 100 years, Bayesian Inference was emp...... hiện toàn bộ
