Effects of bacterial density on growth rate and characteristics of microbial-induced CaCO3 precipitates: a particle-scale experimental study [PDF]
arXiv, 2020 Microbial-Induced Carbonate Precipitation (MICP) has been explored for more than a decade as a promising soil improvement technique. However, it is still challenging to predict and control the growth rate and characteristics of CaCO3 precipitates, which directly affect the engineering performance of MICP-treated soils.

Bacterial biofilms use chiral branches to escape crowded environments by tracking oxygen gradient [PDF]
arXiv, 2022 Bacterial biofilms collectively develop distinct and ordered structures, including fibers, bundles, and branches. Often, it is unclear how these structural motifs convey specific advantages to bacterial strains under challenging conditions. In oxygen-limited environments, dense bacterial aggregates generally deplete oxygen, which leads to arrest of ...

A Hybrid Bacterial Foraging Algorithm For Solving Job Shop Scheduling Problems [PDF]
arXiv, 2012 Bio-Inspired computing is the subset of Nature-Inspired computing. Job Shop Scheduling Problem is categorized under popular scheduling problems. In this research work, Bacterial Foraging Optimization was hybridized with Ant Colony Optimization and a new technique Hybrid Bacterial Foraging Optimization for solving Job Shop Scheduling Problem was ...

Onset of Shear Waves In A Bacterial Bath: A Novel Effect [PDF]
arXiv, 2003 Recent experiments on particle diffusion in bacterial baths indicate the formation of correlated structures in the form of bacterial swirls. Here we predict that such a structural ordering would give rise to the new effect of propagating shear waves in a bacterial bath at length scales of the order of a swirl, which corresponds to time scales of the ...

Case Reports in Vascular Medicine, 2017 The term “mycotic aneurysm” was first used by Osler in 1882 to describe a mushroom-shaped aneurysm in subacute bacterial endocarditis. Mycotic aneurysms account for only 2.6% of all aneurysms of the aorta.

Journal of Rheumatology, 2011 To the Editor: Tumor necrosis factor-α (TNF-α) antagonists are highly effective in treatment of ankylosing spondylitis (AS). However, some patients have an inadequate response and switching the anti-TNF-α inhibitors may be effective after an initial ...

Intracranial complications of acute bacterial endocarditis
Surgical neurology international, 2018 Background: Infectious endocarditis (IE) clinically manifests as either subacute bacterial endocarditis (SBE) or acute bacterial endocarditis (ABE). Neurologic manifestations are markedly different for these two entities.

BMJ Case Reports, 2011 In this case report, the authors demonstrate a case of subacute bacterial endocarditis presenting with anaemia. It is the first of its kind to describe a delay in diagnosis due to an initial patient investigation for a bleed rather than a cardiac ...
