Influences of heat seal lacquer thickness on the quality of blister packages.

2011

A sealability of aluminium lidding foils against formable polymer materials of blister packages is usually achieved by a coating of aluminium with certain grammages of heat seal lacquers. To investigate influences of their thickness on quality of blister packages, lidding foils with different grammages of two lacquer types were manufactured. Sealing experiments (variation of temperature, pressure and sealing time) were performed. Sealed seam strengths were determined with mechanical tensile tests, tightness of cold form blisters were analysed by means of helium leakage tests. Time-dependent moisture uptake of stored blisters was monitored with micro-gas chromatography. By means of a simple …

Survival of Listeria monocytogenes in Soil Requires AgrA-Mediated Regulation

2015

ABSTRACT In a recent paper, we demonstrated that inactivation of the Agr system affects the patterns of survival of Listeria monocytogenes (A.-L. Vivant, D. Garmyn, L. Gal, and P. Piveteau, Front Cell Infect Microbiol 4:160, http://dx.doi.org/10.3389/fcimb.2014.00160 ). In this study, we investigated whether the Agr-mediated response is triggered during adaptation in soil, and we compared survival patterns in a set of 10 soils. The fate of the parental strain L. monocytogenes L9 (a rifampin-resistant mutant of L. monocytogenes EGD-e) and that of a Δ agrA deletion mutant were compared in a collection of 10 soil microcosms. The Δ agrA mutant displayed significantly reduced survival in these b…

Since the beginning of the 20th century, electroencephalography (EEG) has been used in a wide variety of applications, both for medical needs and for the study of various cerebral processes. With the rapid development of the technique, more and more precise and advanced tools have emerged for research purposes. However, the main constraints of these devices have often been the high price and, for some devices the low transportability and the long set-up time. Nevertheless, a broad range of wireless EEG devices have emerged on the market without these constraints, but with a lower signal quality. The development of EEG recording on multiple participants simultaneously, and new technological …

Outcome of Bleb Revision With Autologous Conjunctival Graft Alone or Combined With Donor Scleral Graft for Late-onset Bleb Leakage With Hypotony Afte…

2020

Prcis Treatment of leakage with ocular hypotony after trabeculectomy with mitomycin C (MMC) can be safely achieved through conjunctival patch alone or combined with donor scleral graft in cases of melted underlying sclera. Purpose To report outcomes of 2 surgical approaches for treating ocular hypotony in eyes with blebs with late-onset leakage after standard trabeculectomy with MMC. Methods Thirty consecutive cases with bleb leakage and hypotony underwent bleb revision surgery between 2009 and 2014 by the same surgeon (J.W.) at the Department of Ophthalmology of the Mainz University Medical Center, Germany. In 18 patients, an autologous conjunctival patch graft was applied. In 12 patients,…

Influence of Regular Rhythmic Versus Textural Sound Sequences on Semantic and Conceptual Processing

2021

Conceptual priming studies have shown that listening to musical primes triggers semantic activation. The present study further investigated with a free semantic evocation task, 1) how rhythmic vs. textural structures affect the amount of words evoked after a musical sequence, and 2) whether both features also affect the content of the semantic activation. Rhythmic sequences were composed of various percussion sounds with a strong underlying beat and metrical structure. Textural sound sequences consisted of blended timbres and sound sources evolving over time without identifiable pulse. Participants were asked to verbalize the concepts evoked by the musical sequences. We measured the number …

Pārtikas patogēno baktēriju sastopamība dīgstos un diedzētu sēklu produktos

2019

Pieaugot patērētāju pieprasījumam pēc minimāli apstrādātu produktu lietošanas uzturā, pārtikas drošība ir aktuāla un svarīga, īpaši tādiem termiski neapstrādātiem produktiem kā dīgsti. Eiropā Salmonella spp. un Šiga jeb verotoksīnus producējošā Escherichia coli (STEC) ir visbiežāk minētās patogēnās baktērijas, kas izraisījušas uzliesmojumus, kas asociēti ar kontaminētiem dīgstiem. STEC patogenitāti nodrošina patogenitātes gēni stx1, stx2, bet viens no virulences faktoriem kodēts gēnā eaeA. Listeria monocytogenes ir ievērojams piesārņotājs pārtikā, arīdzan tā ir tipiska augsnes baktērija. Jaunākie pētījumi apraksta ne tikai L. monocytogenes, bet arī Listeria innocua patogenitāti. Pētījumā an…

Semi-blind Independent Component Analysis of functional MRI elicited by continuous listening to music

2013

This study presents a method to analyze blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (tMRI) signals associated with listening to continuous music. Semi-blind independent component analysis (ICA) was applied to decompose the tMRI data to source level activation maps and their respective temporal courses. The unmixing matrix in the source separation process of ICA was constrained by a variety of acoustic features derived from the piece of music used as the stimulus in the experiment. This allowed more stable estimation and extraction of more activation maps of interest compared to conventional ICA methods.
