The occurrence of bacteria in the food processing environments plays a key role in food contamination and development of spoilage. Species of the genus Pseudomonas are recognized as major food spoilers and the capability to actually determine spoilage can be species- as well as strain-dependent. In order to improve the taxonomic resolution of 16S rRNA gene amplicons, in this study we used oligo...

Today, it is very usual to see numerous cars, from commercial cars to sports cars fitted with different types of spoilers on them. The exterior fashioning and aerodynamically well-organized design for reduction of engine load which reflects in the reduction of fuel consumption and producing the down force for the stability are the two essential factors for an effective operation in the modest w...

When high-speed train runs in the environment with a large number of airborne particles, these particles may accumulate on bogie train, which will further challenge normal operation and reduce riding comfort safety. In order to prevent entering into area, different protective devices around are used. However, up present, systematical analysis effects diverse measures against types still very li...

The aim of the study was to assess the in vitro effect of phenols extracted from oil vegetation water (PEOW) on several food-borne strains. Antibacterial activity of PEOW was based on the minimum bactericidal concentration (MBC) on microtitre assay. The taxa tested were: Staphylococcus (n. 5), Listeria (n. 4), Escherichia (n. 2), Salmonella (n. 1), Pseudomonas (n. 3), Lactobacillus (n. 2) and P...

SUMMARY Pressure measurements, flow visualisation tests and force measurements have been made on 45' swept half wings, to examine the flow conditions which prevail, particularly in relation to the effectiveness of an upper surface spoiler as a roll control. Tests were made on l/10 scale half-models in the 3ft x 3ft wind tunnel over a Mach number range 0.5 to 0.9. The wing flow is characterised ...

Carnobacterium, a genus of lactic acid bacteria, frequently dominate the microflora of chilled vacuum- or modified atmosphere-packed meat and seafood. In this study Carnobacterium isolates were characterized by phenotypic and molecular methods in order to investigate the association of species and intra-species groups with distinct kinds of meat and seafood. Of 120 test strains, 50 originated f...

Abstract This paper presents an analysis of the interaction and trade-off between active aeroelastic control passive structural tailoring on a free-flying fully flexible aircraft model. Both technologies are included in preliminary design typical transport configuration with conventional surface layout containing trailing edge surfaces spoilers. The is facilitated by exploiting anisotropic prop...

Abstract The membrane is the major protective barrier separating cell from environment and thus important for bacteria to survive environmental stress. This study investigates changes in lipid compositions physiology of meat spoiling response high CO 2 (30%) O (70%) concentrations, as commonly used modified atmosphere packaging meat. Therefore, fatty acid profile well fluidity, permeability sur...

The Benchmark Active Controls Technology (BACT) project is part of NASA Langley Research Center’s Benchmark Models Program for studying transonic aeroelastic phenomena. In January of 1996 the BACT wind-tunnel model was used to successfully demonstrate the application of robust multivariable control design methods (H∞ and μ-synthesis) to flutter suppression. This paper addresses the design and e...

Introduction Recently, the gradientand spin-echo (GRASE) technique has been used to increase efficiency in Dixon fat-water imaging [1,2]. In these sequences, oscillating gradient lobes are carefully positioned between spin refocusing pulses to acquire multiple echoes with the necessary fat-water phase shifts. As it is necessary to collect at least two echoes with approximately π fat-water phase...
