An orientation experiment using auditory artificial horizon

Presented at the 10th International Conference on Auditory Display (ICAD2004)An orientation experiment was carried out in a spatially immersive virtual environment. The task of subjects was to navigate with 6 degrees of freedom flying method through a predefined route guided by visual cues. Simultaneously they should keep the model oriented in upright position as well as possible. In the experiment we had three different implementations of auditory artificial horizon, and for the reference the subjects accomplish the task also without the auditory support. According to the results the auditory artificial horizon helps subjects to keep the model oriented during the task

Does fluid loading influence measurements of intestinal permeability?

INTRODUCTION: Urinary recovery of enterally administered probes is used as a clinical test of intestinal mucosal permeability. Recently, evidence has been provided that the recovery of some but not all sugar probes is dependent on the amount of diuresis and renal function. The aim of this study was to assess the effect of fluid loading on the urinary recovery of sugar probes in healthy volunteers. METHODS: In a cross-over study, 10 healthy volunteers ingested 100 ml of a solution containing 0.2 g of 3-O-methyl-D-glucose (3-OMG), 0.5 g of D-xylose, 1.0 g of L-rhamnose, and 5.0 g of lactulose on two different days. The volunteers were randomized to receive either 2 litres of Ringer acetate or no fluid during the following 3 hours. The sugar concentrations were measured in 5-hour urine samples period. RESULTS: Fluid loading increased urine production and urinary recovery of xylose. Fluid loading did not influence the urinary recovery of 3-OMG, L-rhamnose, or lactulose. Neither the lactulose/rhamnose ratio nor the 3-OMG/rhamnose ratio changed. CONCLUSION: Fluid loading increases mediated carbohydrate transport but not the lactulose/rhamnose ratio, after oral sugar administration in healthy volunteers. It remains to be determined whether sugar probes are handled differently in response to fluids in patients with organ dysfunctions

Influence of marketing mix strategy in insurance business: The case of Kota Bharu

Malaysia has experience a low penetration for Takaful business despite many growing operators in insurance industry. After 25 years in operation, it is time that Takaful industry is evaluated in terms of its performance. This study provides better understanding on Takaful customer satisfaction in a case of Kota Bharu. Population of this study are customers who have subscribing family Takaful plans in selected Takaful operator at least one years’ experience based on convenience sampling method. A total of 196 questionnaires were distributed and 163 questionnaires were returned. Therefore, this study revealed that the Product, Pricing, Promotion, People and Process towards Takaful operator were positively influence customer satisfaction. Finally, the study found that the Process indicates as the most critical factor that influences customer satisfaction toward Takaful Operator.© 2019 Sciedu Pressfi=vertaisarvioitu|en=peerReviewed

Factor Retention Decisions in Exploratory Factor Analysis Results: A Study Type of Knowledge Management Process at Malaysian University Libraries

Structural equation modeling (SEM) is a versatile statistical modeling tool which uses in the social sciences research. Recently, in Library and Information Science (LIS) environment, structural equation modeling has gained popularity across many disciplines, due to its generality and flexibility. Its estimation techniques, modeling capabilities and breadth of application are expanding rapidly.This paper reported a structural equation modeling through an Exploratory Factor Analysis (EFA) result, which involves 300 lead users at six selected Malaysian university libraries through survey. The decision of how many factors to retain is a critical component of exploratory factor analysis. Evidence is presented that parallel analysis is one of the most accurate factor retention methods. SPSS 20 was utilized to analyze the factor analysis data. In this regards, the results of EFA could provide empirical evidence of each hypotheses construct. It is hoped that the EFA results could be used to level Confirmatory Factor Analysis (CFA) to perform full Structural Equation Modeling.© 2013 The Authors.

New Stone Age Sites to the North of Lake Ladoga in Karelia, Russia

In 2012, the Museum of Lahti and the Museum of Petrozavodsk completed a joint archaeological field project, begun in 2008, in present-day Russian Karelia for the purpose of studying the oldest postglacial settlement of the area between Lake Ladoga and Lake Onega. During the five field seasons, altogether 19 new Stone Age sites were found. Test excavations were carried out at five sites. The finds consisted mostly of burned bone and flakes of quartz and other lithics. The oldest site was found in Harlu at the mouth of the Jänisjoki River, with a dating of ca. 7760 calBC

Complete Genome Sequence of Nisin-Producing Lactococcus lactis subsp. lactis N8

We report here the genome sequence of Lactococcus lactis subsp. lactis N8, a nisin producer isolated in the 1960s from a dairy product in Finland. The genome consists of a 2.42-Mb chromosome and two plasmids of 80.3 and 71.3 kb.Peer reviewe

Phenotypic comparison and DNA sequencing analysis of a wild-type and a pediocin-resistant mutant of Listeria ivanovii

Listeria ivanovii is one of the two pathogenic species within the genus Listeria, the other being L. monocytogenes. In this study, we generated a stable pediocin resistant mutant Liv-r1 of a L. ivanovii strain, compared phenotypic differences between the wild-type and the mutant, localised the pediocin-induced mutations in the chromosome, and analysed the mechanisms behind the bacteriocin resistance. In addition to pediocin resistance, Liv-r1 was also less sensitive to nisin. The growth of Liv-r1 was significantly reduced with glucose and mannose, but less with cellobiose. The cells of Liv-r1 adsorbed less pediocin than the wild-type cells. Consequently, with less pediocin on the cell surface, the mutant was also less leaky, as shown as the release of intracellular lactate dehydrogenase to the supernatant. The surface of the mutant cells was more hydrophobic than that of the wild-type. Whole genome sequencing revealed numerous changes in the Liv-r1 chromosome. The mutations were found e.g., in genes encoding sigma-54-dependent transcription regulator and internalin B, as well as in genes involved in metabolism of carbohydrates such as glucose and cellobiose. Genetic differences observed in the mutant may be responsible for resistance to pediocin but no direct evidence is provided.Peer reviewe

Pulse pressure variation and volume responsiveness during acutely increased pulmonary artery pressure: an experimental study

We found that pulse pressure variation (PPV) did not predict volume responsiveness in patients with increased pulmonary artery pressure. This study tests the hypothesis that PPV does not predict fluid responsiveness during an endotoxin-induced acute increase in pulmonary artery pressure and right ventricular loading
