Children on exclusive jejunal feeding may be at risk of iron deficiency due to the feeds bypassing the duodenum,which is the primary site for iron *** describe the biochemical and hematological features of six children on exclusive jejunal feeding who did not receive iron *** a mean(standard deviation)period of 11(6.5)mo after commencing jejunal feeds,there was a significant reduction in both serum iron(18.5 g/L vs 9.8 g/L,P=0.01)and transferrin saturation levels(23.1%vs 13.7%,P=0.02),suggesting iron ***,there was no significant change in ferritin,hemoglobin and mean corpuscular volume levels post-commencement of jejunal *** may be the result of small bowel adaptation in response to early iron *** and longer term prospective studies are required to investigate if children on jejunal feeds are at risk of developing iron deficiency.

The purpose of this study is to investigate the approaches applied to analyze solid oxide fuel cell (SOFC) microstructural properties. Both manual and automated image processing approaches applied on SOFC microstructural images which are obtained from several types of tomography such as dual-beam focused ion beam with scanning electron microscopy (FIB-SEM), Electron Backscatter Diffraction (EBSD) and others are discussed. In fact, to achieve a realistic and accurate SOFC microstructural properties, such as average diameter, volume fraction, triple phase boundary (TPB), area interface density and tortuosity factor, the approaches of image processing and quantification are crucial for a reliable image generation for quantification purposes. The microstructural properties are optimized to improve SOFC electrode performance. Therefore, the image processing and quantification approaches are outlined and reviewed. Despite the automated image processing and quantification algorithms significantly outperform manual image processing and quantification approaches in terms of computing speed when evaluating and measuring microstructural properties, the efficiency and productivity are still extremely taken into concern. As a result, image processing and quantification approaches are concluded and presented respectively in this paper.

Small-sized droplets/aerosol transmission is one of the factors responsible for the spread of COVID-19,in addition to large droplets and surface contamination(fomites).While large droplets and surface contamination can be relatively easier to deal with(i.e.,using mask and proper hygiene measures),aerosol presents a different challenge due to their ability to remain airborne for a long *** calls for mitigation solutions that can rapidly eliminate the airborne ***-COVID-19,air ionizers have been touted as effective tools to eliminate small *** this work,we sought to evaluate the efficacy of a novel plant-based ionizer in eliminating *** was found that factors such as the ion concentration,humidity,and ventilation can drastically affect the efficacy of aerosol *** aerosol removal rate was quantified in terms of ACH(air changes per hour)and CADR-(clean air delivery rate-)equivalent unit,with ACH as high as 12 and CADR as high as 141 ft^(3)/minute being achieved by a plant-based ionizer in a small isolated *** work provides an important and timely guidance on the effective deployment of ionizers in minimizing the risk of COVID-19 spread via airborne aerosol,especially in a poorly-ventilated environment.
