The present work examines the potential of sesquiterpenoids to sensitize Escherichia coli and Staphylococcus aureus, and modulate their susceptibility to the standard antibiotics ciprofloxacin, erythromycin, gentamicin and vancomycin. It was tested samples of three sesquiterpenoids: guaiazulene, nerolidol (racemic mixture of the cis and trans isomers) and germacrene D enriched natural extract. ...

Within microfluidic technologies, the centrifugal “Lab-on-a-Disc” (LoaD) platform offers great potential for use at PoC and in low-resource settings due to its robustness ability port miniaturize ‘wet bench’ laboratory protocols. We present combination of ‘event-triggered dissolvable film valves’ with a centrifugo-pneumatic siphon structure enable control timing, through changes disc spin-speed...

Single items from a typical clinical examination have proved disappointing in their predictive value for temporomandibular joint (TMJ) disc displacement. Only one criterion (the 12 o'clock) is used to diagnose normal disc position. According to this criterion, the posterior band of the disc should be located at the top of the condyle, at the 12 o'clock position. The purpose of this study was to...

Abstract Automotive brakes have come a long way, from drum being widely used for time until disc came along and began slowly wiping out the usage of brakes. This is primarily due to number advantages that disc-pad setup brings - better stopping distance one most important aspects any braking system. Apart this, key over include heat dissipation, fade resistance, self-adjusting ability, compact ...

A sugarcane harvester prototype was fabricated and evaluated to save time, labor, harvesting expenses, which are included in production costs. The single-row fits the functional needs of physical qualities designed be installed on a tractor. One serrated edge cutter disc, three forward speeds, disc speeds were used evaluate performance harvester. results technical evaluation showed that average...

The purpose of the present paper is to study some results involving coefficient conditions, extreme points, distortion bounds, convolution conditions and convex combination for a new class of harmonic multivalent functions in the open unit disc. Relevant connections of the results presented here with various known results are briefly indicated.

BACKGROUND Nonarteritic ischemic optic neuropathy affects the anterior portion of the optic nerve and is characterized by sudden, painless visual loss. The affected eye has a relative afferent pupillary defect. The typical funduscopic appearance includes optic disc edema, with associated nerve fiber layer hemorrhage. Risk factors include advanced age, systemic hypertension, nocturnal hypotensio...

We show that every rigid motion invariant and upper semicontinuous valuation on the space of convex discs is a linear combination of the Euler characteristic, the length, the area, and a suitable curvature integral of the convex disc. 1991 AMS subject classification: 52A10, 53A04

background & aim: lumbosacral pain is extremely common as age increases. spinal instrumentation is sometimes recommended for lumbar canal stenosis and disk herniation surgery. this study aimed at studying the frequency of instrumentation in patients referring to our center. methods & materials/patients: this retrospective cross-sectional study included 1200 patients with low back and/or radicul...

The velocity dispersion of nearby stars in the Galactic disc are well known to increase substantially with age; this is the so-called Age-Velocity relation, and is interpreted as a “heating” of the disc as a function of time. We have studied the heating of the Galactic stellar disc due to giant molecular clouds and halo black holes, via simulations of the orbits of tracer stars embedded in a pa...
