Use of the Weibull model to describe inactivation of dry harvested conidia of different Penicillium species by ethanol vapours

2010

Aims:  This study aimed at modelling the effect of ethanol vapours, in the range 0·7–7·5 kPa, on the inactivation of dry-harvested conidia of Penicillium chrysogenum, Penicillium digitatum and Penicillium italicum. Methods and Results:  Survival curves were modelled by a Weibull model: log (N/N0) = −1/2·303 (t/α)β. The shape parameter β was different from one in all cases, indicating that the classical first-order kinetics approach is the exception rather than the rule. Survival curves exhibited upward concavity (β < 1) with the notable exception of P. chrysogenum at ethanol vapour pressures 0·7 and 1·5 kPa. The scale parameter α (h) varied greatly depending on the ethanol vapour pressure a…

Quantitative Bestimmung der Hirnperfusion mit Hilfe der digitalen Subtraktionsangiographie (DSA)

1990

In a search for a reliable and relatively non-invasive method for quantifying cerebral perfusion, we examined the possible role of DSA. By using special software, it is possible to demonstrate vascular morphology and obtain functional data concerning blood flow. Regions of interest are used for obtaining time-density curves and these are evaluated by a formula designed by Meier and Zierler. Perfusion through the arterial territory in both cerebral hemispheres was correlated with the clinical symptoms of the patients and with the morphological findings. Difficulties and problems are described and discussed.

Sprint Acceleration Mechanics in Fatigue Conditions: Compensatory Role of Gluteal Muscles in Horizontal Force Production and Potential Protection of …

2018

Aim: Hamstring muscle injury is the main injury related to sports requiring sprint acceleration. In addition, hamstring muscles have been reported to play a role in horizontal force production during sprint acceleration performance. The aim of the present study was to analyze (i) the determinants of horizontal force production and (ii) the role of hip extensors, and hamstring muscles in particular, for horizontal force production during repeated sprint-induced fatigue conditions. Method: In this experimental laboratory setting study including 14 sprint-trained male athletes, we analyzed (i) the changes in sprint mechanics, peak torque of the knee and hip extensors and flexors, muscle activi…

Location Based Information Storage and Dissemination in Vehicular Ad Hoc Networks

2010

Vehicular Ad Hoc Networks (VANETs) is an emerging type of information networks in urban areas. A lot of research has been done in the area of increasing the vehicle awareness by disseminating collision and congestion warnings, and parking place availability information. In this paper we propose a novel idea and framework for dissemination of location based information, called digital maps, which are useful not only directly for the drivers and vehicle onboard navigation systems, but also external entities, such as tourists, environmental scientists, emergency services, advertisement companies. Centralized authority defines cooperative knowledge collection tasks and disseminates orders in th…

Trolling as a Digital Literary Practice in the Russian Language Internet

2020

This article explores trolling as a form of literary activity. It presents a number of specific types of trolling on the Russian-language Internet in connection with digital literature and the literary practices of various groups of Internet users. Techniques for writing provocative “troll-texts” were created and developed within subcultural groups in the 1990s. Later, from being a subversive practice known only to a few insiders, it became a mass technique described in meta-texts that identified rules for trolling and shared facts about its culture with all interested users. In the 2010s, the now popularised techniques of trolling came to be seen as effective strategies to deploy in online…

The discursive legitimation strategies of a nascent market

2017

Since the introduction of Gold&Green Foods Ltd’s Pulled Oats (Nyhtökaura) to the Finnish market in the spring 2016, the Finnish media has been increasingly reviewing different plant-based protein products. Gold&Green Ltd’s Pulled Oats has experienced extensive media coverage amongst other Finnish plant-based protein products which have been launched during 2016 such as VersoFood Ltd’s Härkis, Viipurilainen Kotileipomo’s Puhtikaura etc. It has yet to be seen whether the sudden inception of several plant-based protein product innovations will be defined as a pivotal era in the Finnish food industry or just a passing trend. Finnish media has aldo categorized MiFu as one of the up and coming fo…

Optimized FPGA-implementation of quadrature DDS

2003

This paper presents the optimized implementation of high performance quadrature direct digital synthesizers (DDS). Although VLSI designs and optimizations have already been discussed in the literature they may not be successfully translated into an FPGA-based technology. This work examines each phase-to-amplitude mapping technique, such as ROM compression and partitioning techniques and the CORDIC algorithm, and it proposes the most suitable structure for Virtex FPGAs in order to obtain the most efficient implementation in terms of area and throughput.

AER Filtering Using GLIDER: VHDL Cellular Automata Description

2008

Cellular Automata (CA) is a bio-inspired processing model for problem solving, initially proposed by Von Neumann. This approach modularizes the processing by dividing the solution into synchronous cells that change their states at the same time in order to get the solution. The communication between them is crucial to achieve the correct solution. On the other hand, the Address-Event-Representation (AER) is a neuromorphic communication protocol for transferring asynchronous events between VLSI chips. These neuro-inspired implementations have been used to design sensor chips (retina, cochleas), processing chips (convolutions, filters) and learning chips, which makes it possible to develop co…

Treatment of Specific Types of Nystagmus

2007

■ The function of the ocular motor system is to hold images stable on the fovea. The vestibular system and the vestibulo-ocular reflex (VOR) also play an important role in this function. The VOR connects the peripheral vestibular endorgans – the semicircular canals and otoliths – with their appropriate pair of eye muscles via a three-neuronal arc.
