Three popular 100% cotton knitted fabrics, (plain single-jersey, 1x1 rib and interlock) were subjected to five cycles of four different washing and drying regimes. This was in order to investigate the effect of laundering with detergent as opposed to water, and tumble drying against line drying. The main aim of this work was to systematically investigate the effect of the principal washing and ...

Many organisms navigate gradients by alternating straight motions (runs) with random reorientations (tumbles), transiently suppressing tumbles whenever attractant signal increases. This induces a functional coupling between movement and sensation, since tumbling probability is controlled by the internal state of the organism which, in turn, depends on previous signal levels. Although a negative...

INTRODUCTION During a coordinated turn, subjects can misperceive tilts. Subjects accelerating in tilting-gondola centrifuges without external visual reference underestimate the roll angle, and underestimate more when backward-facing than when forward-facing. In addition, during centrifuge deceleration, the perception of pitch can include tumble while paradoxically maintaining a fixed perceived ...

The phosphorylated form of the response regulator CheY promotes the tumble signal in Escherichia coli chemotaxis. Phospho-CheY is thought to interact with the switch at the base of the flagellar motor and cause reversal of flagellar rotation from counterclockwise to clockwise changing the swimming direction. Thus the level of phospho-CheY controls the direction of flagellar rotation. The decay ...

The Partial Transmit Sequence which reduces the PAPR (Peak-to-Average Power Ratio) in Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system using a novel optimization algorithm is proposed in this study. This novel optimization algorithm is based on a hybrid of Bacterial Foraging Optimization (BFO) and Modified Cuckoo Search algorithm (MCS) and is thus cal...

1. Abstract The automotive industry is facing increasing demands in terms of cost reduction and environment responsibility. To comply with new European emission standards, while satisfying the need for higher engine performances, the intake ports have to be optimized with respect to the mass flow rate and the aerodynamic turbulence inside the combustion chamber. In this study, the shape of an i...

The common bed bug, Cimex lectularius (L.) (Hemiptera: Cimicidae) is known to become associated, from time to time, with clothing or linen. In such locations, it may escape insecticide treatment, and may be carried to new locations. We test the suggestion that laundering is sufficient to kill all life stages and thus help prevent reinfestation and dispersion. We establish minimum temperatures f...

We investigate the statistics of convex hull for a single run-and-tumble particle in two dimensions. Run-and-tumble particle, also known as persistent random walker, has gained significant interest recent years due to its biological application modelling motion bacteria. consider different statistical ensembles depending on whether (i) total number tumbles $n$ or (ii) observation time $t$ is ke...

In an internal combustion engine, performance, efficiency and emission formation depends on the of air-fuel mixture inside engine cylinder. The fluid flow dynamics plays important role for preparation to obtain better combustion, performance efficiency. This review article discuss rotating (swirl tumble) in premixed spark-ignition its effect turbulence generation flame propagation. Rotating can...
