The effect of field size, velocity, and visual fixation upon the perception of self-body rotation and tilt was examined in a rotating furnished room. Subjects sat in a stationary chair in the furnished room which could be rotated about the body roll axis. For full-field conditions, complete 360 degrees body rotation (tumbling) was the most common sensation (felt by 80% of subjects). Constant ti...

The molecular dynamics of tetramethylstibonium hexafluorophosphate, [Sb(CH3)4]PF6 , is investigated over a broad temperature range. NMR spin lattice relaxation times and the N M R second moments of the *H and F nuclei were determined in the range 8.6 < T/K ^ 332.3 for polycrystalline [Sb(CH 3) 4]PF 6 . The complex cation undergoes isotropic tumbling for T > 2 6 0 K and thermally activated methy...

The effect of different tumbling marination treatments (control group, CG; conventional static marination, SM; vacuum continuous tumbling marination, CT; vacuum intermittent tumbling marination, IT) on the quality characteristics of prepared pork chops was investigated under simulated commercial conditions. The CT treatment increased (p<0.05) the pH value, b* value, product yield, tenderness, o...

The purpose of this study is automated handling of massive rocks for moving them to a proper place and for breaking them down at a rock quarry. This paper reports our first approach in laboratory environment using a robotic manipulator with a small sized laser range finder(LRF) to handle a relatively small object. For tumbling operation, we apply image processing techniques onto range images cr...

Tank-treading, tumbling, and trembling are different types of the vesicle behavior in an external flow. We derive a dynamical equation enabling us to establish a state of nearly spherical vesicles. For a 2D external flow, the character of the vesicle dynamics is determined by two dimensionless parameters, depending on the vesicle excess area, fluid viscosities, membrane viscosity and bending mo...

Previously we showed that an Escherichia coli hemH mutant, defective in the ultimate step of heme synthesis, ferrochelatase, is somewhat better than 100-fold more sensitive than its wild-type parent in tumbling to blue light. Here we explore the effect of a hemG mutant, defective in the penultimate step, protoporphyrinogen oxidase. We found that a hemG mutant also is somewhat better than 100-fo...

A three-dimensional (3D) simulation study of the effect of inertia on the dynamics of vesicles and red blood cells (RBCs) has not been reported. Here, we developed a 3D model based on the front tracking method to investigate how inertia affects the dynamics of spherical/non-spherical vesicles and biconcave-shaped RBCs with the Reynolds number ranging from 0.1 to 10. The results showed that iner...

PurposeTo assess the influence of distance and near visual impairment on self-reported functioning (VF) in a multinational study.DesignPopulation-based cross-sectional study.ParticipantsParticipants aged 35 years or older were selected randomly with cluster sampling at 7 sites: rural sites Nepal (Kaski) India (Madurai), semirural site China (Shunyi), semiurban South Africa (Durban) Niger (Dosso...

Simple presentation graphics are intuitive and easyto-use, but show only highly aggregated data and present only a very limited number of data values (as in the case of bar charts), and may have a high degree of overlap which may occlude a significant portion of the data values (as in the case of the x-y plots). In this paper, we therefore propose a generalization of traditional bar charts and ...

We measured detection and resolution acuity for vanishing optotype tumbling E stimuli in both the fovea and at 30 degrees in the periphery to determine if peripheral resolution is sampling limited for this stimulus. In the fovea, where acuity is optically limited, detection and resolution were the same. At 30 degrees, however, detection was markedly better than resolution indicating that periph...
