Using high-speed imaging we assessed Streptococcus mutans biofilm-fluid interactions during exposure to a 60-ms microspray burst with a maximum exit velocity of 51m/s. S. mutans UA159 biofilms were grown for 72h on 10mm-length glass slides pre-conditioned with porcine gastric mucin. Biofilm stiffness was measured by performing uniaxial-compression tests. We developed an in-vitro interproximal m...

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

Abstract In this research, an attempt has been made to evaluate the structural response of multi‐storey composite modular buildings when subjected lateral wind loads. Finite element (FE) models were developed in Abaqus for a general 10 storey building, with and without consideration load resisting mechanisms shear walls. Concrete filled steel tubular (CFST) columns walls proposed place conventi...

BACKGROUND Proliferative glomerulonephritides are characterized by the influx of leucocytes. Heparan sulfate (HS) plays an important role in the recruitment, rolling and firm adhesion of leucocytes to activated endothelium. Recently, we have shown the importance of HS on activated mouse glomerular endothelial cells (mGEnC-1) for the firm adhesion of leucocytes in a static adhesion assay. In the...

an efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. the bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. the box-behnken design (bbd) was employed to design the experiments, to ...

This work presents first quantitative results of a method for automatic liver segmentation from CT data. It is based on a 3D deformable model approach using a-priori statistical information about the shape of the liver gained from a training set. The model is adapted to the data in an iterative process by analysis of the grey value profiles along its surface normals after nonlinear diffusion fi...

MUCOCILIARY TRANSPORT IS a vital component of host defense and plays a crucial role in the removal of foreign materials within the airways. A dysfunction of ciliary beating can lead to serious respiratory problems such as airflow obstructions or Kartagener syndrome. The airway ciliary beat frequency (CBF) increases in response to a variety of stimulations, such as parasympathetic or sympathetic...

Bone fractures are in need of rapid fixation methods, but the current strategies limited to metal pins and screws, which necessitate secondary surgeries upon removal. New techniques sought avoid surgical revisions, while maintaining or improving speed. Herein, a method bone is proposed with transparent biopolymers anchored place via light-activated biocomposites based on expanding CaproGlu bioa...
