IJERPH, Vol. 16, Pages 3521: How Safe is Chicken Litter for Land Application as an Organic Fertilizer? A Review International Journal of Environmental Research and Public Health doi: 10.3390/ijerph16193521 Authors: Kyakuwaire Olupot Amoding Nkedi-Kizza Basamba Chicken litter application on land as an organic fertilizer is the cheapest and most environmentally safe method of disposing of the volume generated from the rapidly expanding poultry industry worldwide. However, little is known about the safety of chicken litter for land application and general release into the environment. Bridging this knowledge gap is crucial for maximizing the benefits of chicken litter as an organic fertilizer and mitigating negative impacts on human and environmental health. The key safety concerns of chicken litter are its contamination with pathogens, including bacteria, fungi, helminthes, parasitic protozoa, and viruses; antibiotics and antibiotic-resistant genes; growth hormones such as egg and meat boosters; heavy metals; and pesticides. Despite the paucity of literature about chicken litter safety for land application, the existing information was scattered and disjointed in various sources, thus making them not easily accessible and difficult to interpret. We consolidated scattered pieces of information about known contaminants found in chicken litter that are of potential risk to human, animal, and environmental health and how they are spread. This review tested the ...

Authors: Lopez RN, Lemberg DA Abstract Gastro-oesophageal reflux (GOR) in infancy is common, physiological and self-limiting; it is distinguished from gastro-oesophageal reflux disease (GORD) by the presence of organic complications and/or troublesome symptomatology. GORD is more common in infants with certain comorbidities, including history of prematurity, neurological impairment, repaired oesophageal atresia, repaired diaphragmatic hernia, and cystic fibrosis. The diagnosis of GORD in infants relies almost exclusively on clinical history and examination findings; the role of invasive testing and empirical trials...

This study of the #acadv chat community details a longitudinal study about a digital learning network comprised of academic advising professionals who work in higher education. We discuss how networked communities of practice (CoP) scaffold professional learning and development of post-secondary educators, while also contributing to their daily practice. Utilizing Twitter chat transcripts, digital documents, social media platforms, and interviews with 17 participants of this community, we report 22 topics discussed with the top five themes focused on student needs, orientation support, advising approaches and structures, w...

As synthesized dendritic fibers are directly mixed into the organic paint formulation and applied over the steel surface by brush painting. The morphology of dendritic fibers was characterized by F...

In this study, SS attached to plant bodies were subjected to acid and heat treatments, followed by grinding, to obtain 10–40-nm siliceous sponge spicules (SSS). SSS and polylactic acid (PLA) were then combined to create 50–450-nm PLA/SSS composite nanofibers. The morphology and bioactivity of the electrospun PLA/SSS nanofibers were examined; the tensile, thermal, and water-resistant properties of the fibers were also evaluated. Our results showed a dramatic enhancement in the thermal and tensile properties of PLA with increasing SSS content; specifically, a 3 wt% increase in SSS content resulted in a 47&nb...
