Preliminary Analysis of the Anti-biofilm Efficacy of Manuka Honey on Extended Spectrum Β-lactamase Producing Escherichia Coli Tem-3 and Klebsiella Pneumoniae Shv18, Associated with Urinary Tract Infections
open access articleUrinary Tract Infections (UTIs) are one of the most common infections in the UK and many other parts of the world. The prevalence of the Extended Spectrum β-Lactamases (ESBLs) producing UTIs, combined with their ability to form a bio film, has significantly risen and is limiting therapeutic options. This study investigated the anti-bio film activity of Manuka honey on two ESBL producing pathogens, Escherichia coli TEM-3 and Klebsiella pneumonia SHV18, commonly found in UTIs. The ESBL production was confirmed by the double disk synergy method used to confirm the ESBL production. The antibacterial activity of Manuka honey was determined using the agar well diffusion method. The Minimum Inhibitory Concentration (MIC) was established using serially diluted honey ranging from 50% to 1.56%. The effect of Manuka honey on the pathogen bio films was analysed using the Tissue Culture Plate method, with an established MIC and under 24h incubation with the honey. The results indicated that K. pneumonia SHV18 is a stronger bio film producer than E. coli TEM 3. 50% (w/v) MIC Manuka honey appears to fully prevent the plank tonic growth of both strains. A significant reduction of 81% of the E. coli TEM3 (p < 0.001) and 52% of the K. pneumonia SHV18 (p = 0.001) bio film biomass was observed. The E. coli bio films were found to be more sensitive to the 50% (w/v) honey dilution than those produced by K. pneumonia. The study indicated the anti-bio film potency of Manuka honey and its potential to become an alternative treatment for the ESBL producing pathogens associated with UTIs

Soft reboot : the making of Hard Reset
textDirector, Writer and MFA Candidate Deepak Chetty will discuss his history as a filmmaker from an early age up until present day as well as the entire process of conceptualizing, creating, producing and finishing Hard Reset. Hard Reset, a science fiction thriller is the first short film out of UT3D and the first graduate thesis film shot natively in stereoscopic 3D in North America.Radio-Television-Fil
A conceptual design for squeeze film bearings
Squeeze film bearings which require at least one of two adjacent surfaces to oscillate at high frequency and low amplitude have the oscillating /strain-producing/ member on a double gas film. This means of support allows dynamic changing of the gap between the bearing surfaces without the disadvantages produced when the oscillator is affixed to the bearing base itself

Compressible Air Entrapment in High-Speed Drop Impacts on Solid Surfaces
Using high-speed photography coupled with optical interference, we
experimentally study the air entrapment during a liquid drop impacting a solid
substrate. We observe the formation of a compressed air film before the liquid
touches the substrate, with internal pressure considerably higher than the
atmospheric value. The degree of compression highly depends on the impact
velocity, as explained by balancing the liquid deceleration with the large
pressure of compressed air. After contact, the air film expands vertically at
the edge, reducing its pressure within a few tens of microseconds and producing
a thick rim on the perimeter. This thick-rimmed air film subsequently contracts
into an air bubble, governed by the complex interaction between surface
tension, inertia and viscous drag. Such a process is universally observed for
impacts above a few centimeters high
A tale of two courses: challenging Millenials to experience culture through film
In this article, we discuss how adding a final film project to a revised \u27Culture through Film\u27 course led to deeper student learning and higher rates of student success, as well as increased student satisfaction. Ultimately, we urge social science educators to include experiential projects in their courses that connect to all learning styles. Such projects should also challenge students to \u27create\u27, a task that requires generating ideas, planning and ultimately producing something, which, according to Bloom\u27s taxonomy, engages students in the highest cognitive process (Anderson and Krathwohl 2000). Although this class focused on the intersections of culture and film and was taught at an American university, we believe these lessons apply more broadly
Modeling the buckling and delamination of thin films
I study numerically the problem of delamination of a thin film elastically
attached to a rigid substrate. A nominally flat elastic thin film is modeled
using a two-dimensional triangular mesh. Both compression and bending
rigidities are included to simulate compression and bending of the film. The
film can buckle (i.e., abandon its flat configuration) when enough compressive
strain is applied. The possible buckled configurations of a piece of film with
stripe geometry are investigated as a function of the compressive strain. It is
found that the stable configuration depends strongly on the applied strain and
the Poisson ratio of the film. Next, the film is considered to be attached to a
rigid substrate by springs that can break when the detaching force exceeds a
threshold value, producing the partial delamination of the film. Delamination
is induced by a mismatch of the relaxed configurations of film and substrate.
The morphology of the delaminated film can be followed and compared with
available experimental results as a function of model parameters.
`Telephone-cord', polygonal, and `brain-like' patterns qualitatively similar to
experimentally observed configurations are obtained in different parameter
regions. The main control parameters that select the different patterns are the
mismatch between film and substrate and the degree of in-plane relaxation
within the unbuckled regions.Comment: 8 pages, 10 figure
