The broiler industry produces efficiently animal protein, but generates residues with high contents of N, P, K, trace minerals, and high bacterial charge. The rapid microbial decomposition of these ...residues cause ammonia volatilization, nuisance odor, fine particulate matter, and attract insects and rodents. This presentation will discuss the more effective methods to utilize these resources and minimize potential environmental impact. These procedures include planning, personnel training, zoning of areas used to dispose the final residues in crop lands, farm isolation, precision nutrition, litter and house management practices, and appropriate mortality disposal. Broiler litter has been used for animal feeding and power generation. Additionally, new technologies to reduce ammonia, odor and fine particle emissions, or reduction of P solubility will be presented.
A criação industrial de frangos de corte tem sido eficiente na produção de proteína animal, no entanto geram resíduos com alto conteúdo de N, P, K, minerais traço, e alta carga de bactérias. A rápida degradação microbiana destes resíduos ocasiona volatilização de amônia, odores, e pó fino, além de atrair insetos e roedores. Esta apresentação discutirá os métodos mais efetivos para aproveitamento destes recursos e minimizar o possível impacto ambiental. Estes procedimentos incluem planejamento, capacitação do pessoal, zoneamento das áreas para dispor dos resíduos finais nas glebas, isolamento da granja, nutrição com precisão, praticas de manejo da cama e galpão, e correto manejo das aves mortas. A cama de frangos tem sido utilizada na alimentação animal e geração de energia. Adicionalmente serão apresentadas novas tecnologias visando à redução de emissões de amônia, odores e pó fino, ou a redução na solubilidade de fósforo.

BK virus (BKV) is a human polyomavirus that remains latent in the urinary tract epithelium in most individuals. However, in immunocompromised states, including after hematopoietic stem cell ...transplantation (HSCT), BKV may reactivate and cause infection predominantly affecting the bladder, commonly manifested as hemorrhagic cystitis. Renal insufficiency, occasionally requiring hemodialysis, is not uncommon and was previously attributed to medications or the development of tubulointestitial nephritis. We report a series of 6 HSCT recipients who developed obstructive uropathy of the upper urinary tract system secondary to inflammation and hemorrhage involving the upper uroepithelium, causing ureteral stenosis. Temporary placement of a percutaneous nephrostomy catheter relieved the obstruction and significantly improved kidney function, successfully preventing progression to more advanced renal disease in these patients.
MicroBooNE is a neutrino experiment located in the Booster Neutrino Beamline
(BNB) at Fermilab, which collected data from 2015 to 2021. MicroBooNE's liquid
argon time projection chamber (LArTPC) is ...accompanied by a photon detection
system consisting of 32 photomultiplier tubes used to measure the argon
scintillation light and determine the timing of neutrino interactions. Analysis
techniques combining light signals and reconstructed tracks are applied to
achieve a neutrino interaction time resolution of $\mathcal{O}(1\,\text{ns})$.
The result obtained allows MicroBooNE to access the ns neutrino pulse structure
of the BNB for the first time. The timing resolution achieved will enable
significant enhancement of cosmic background rejection for all neutrino
analyses. Furthermore, the ns timing resolution opens new avenues to search for
long-lived-particles such as heavy neutral leptons in MicroBooNE, as well as in
future large LArTPC experiments, namely the SBN program and DUNE.
