Computerized analyses were performed on the movement of spermatozoa recorded with a high-speed camera. These provide evidence for active bending waves over the entire length of the flagellum and a single equation for waves in all cases examined. In the equation, the angular direction of the flagellum at any distance from the base is expressed by a sine function of time plus a constant, and thus flagellar waves are ‘sine-generated’. To explain the waves a model was proposed in which the active force required to generate sliding between peripheral microtubules is propagated along and around the flagellar axoneme.

Experiments were performed to examine ice-wave interaction that the waves attenuate under continuation ice sheet and at ice floes. The analysis of ice-wave interaction and numerical calculation of the wave attenuation in floe zone are still important problems. It was understood that the reasons of the attenuation are creep, viscous, reflection and collision, and the viscosity has been calculated by using hydrodynamics method in the water boundary layer. Proportion of the every reason and the quantitative analysis has been done.

Classical least square (CLS) algorithm is applied in this thesis to develop the raw spectra corrected peak area model, the raw spectra corrected peak height model, the 2ndderivative spectra corrected peak area model and the 2ndderivative spectra corrected peak height model by NIR spectra data of the wheat flour samples with lime added in. The result indicated that the correlation coefficients of the 4 models are 0.9321, 0.9483, -0.9491 and -0.9482 respectively; the result of F-test indicated that a remarkable correlation exists between the specified values of lime in wheat flour and the the raw spectra corrected peak areas / heights or the 2ndderivative spectra corrected peak areas / heights, which indicated that CLS algorithm has a certain potential application in the quantitative analysis of lime in wheat flour by NIR spectra data. Meanwhile, the result of F-test indicated that a very remarkable correlation exists between the estimated and specified values both the calibration set and external validation set of the 4 models. The limit of detection of the 4 models are 4.83 %, 4.14 %, 4.14 % and 4.17 % respectively, which will be suitable for the rapid quality screening for the wheat flour in the market and will be of great importance to the quality screening of wheat flour in the market, guarantee of the customers' health and the design and manufacturing of the special NIR spectrometer.

Abstract The present paper discusses issues related to the translation of the English personal pronoun you in the French translations of Virginia Woolf’s The Waves (1931). There are two published French translations of The Waves. The first one, Les Vagues, was translated by Marguerite Yourcenar and published in 1937. Around fifty years later, another version was published, under the same title but this time translated by Cécile Wajsbrot (1993). The two versions differ significantly when the use of tu and vous is concerned. This paper is concerned specifically with the original’s mind-style (Fowler 1977) in other words, the way the characters’ perceptions and thoughts, as well as their speech, are presented through language and how this is rendered in the translations. The quantitative analysis was realised using corpus-based studies tools which proved to be an asset in helping to identify the novels’ mind-style.


Purpose. The forecast of a condition of a beach of the city of Nikolayev, the general offers of measures of its protection against degradation. Methods. The forecast of a condition of a beach of the city of Nikolayev is made with use of methods of mathematical statistics and mathematical modeling, the comparative analysis, cartographic and graph analytical researches. Results. The beach of the city of Nikolayev is a strip of coast of the big water object where features of reforming of coasts of reservoirs and the rivers united. The location of the beach on the convex shore of the Bug estuary creates the conditions for the accumulation of sand due to the coastal movement of sediments downstream. However, the width of the estuary and the depth contribute to the formation of wind turbulence in the sector S-Z-Pn, which can destroy the beach. On the beach during the spring floods or in severe down pouring phenomena, long-coastal movement of sands in large volumes is possible depending on the duration of strong currents, but the transportation of sediments along the beach does not significantly affect changes in the outline of its coastal slope. Significant destruction of the beach can occur from storms of rare recurrence in the sector S-SW. Western frontal storms form a profile of relative dynamic equilibrium and contribute to the movement of sands to depth. When the waves approach at an angle to the shoreline is the longitudinal transport of sand. Protection of the beach from erosion can be done by passive or active methods. Further research will focus on a quantitative analysis of the scenario of sand movement along the beach with its accumulation on the protruding part of the beach (point C) and washing away the accumulated sand to a depth under the influence of western storms. Conclusion. Without acceptance of special measures for protection the beach of Nikolayev in the future will degrade.

Quantitative image analysis systems have been used for several years in research and quality control applications in various fields including metallurgy and medicine. The technique has been applied as an extension of subjective microscopy to problems requiring quantitative results and which are amenable to automatic methods of interpretation.Feature extraction. In the most general sense, a feature can be defined as a portion of the image which differs in some consistent way from the background. A feature may be characterized by the density difference between itself and the background, by an edge gradient, or by the spatial frequency content (texture) within its boundaries. The task of feature extraction includes recognition of features and encoding of the associated information for quantitative analysis.Quantitative Analysis. Quantitative analysis is the determination of one or more physical measurements of each feature. These measurements may be straightforward ones such as area, length, or perimeter, or more complex stereological measurements such as convex perimeter or Feret's diameter.

An important example of intracellular particles is encountered in silicosis where alveolar macrophages ingest inspired silica particles. The quantitation of the silica uptake by these cells may be a potentially useful method for monitoring silica exposure. Accurate quantitative analysis of ingested silica by phagocytic cells is difficult because the particles are frequently small, irregularly shaped and cannot be visualized within the cells. Semiquantitative methods which make use of particles of known size, shape and composition as calibration standards may be the most direct and simplest approach to undertake. The present paper describes an empirical method in which glass microspheres were used as a model to show how the ratio of the silicon Kα peak X-ray intensity from the microspheres to that of a bulk sample of the same composition correlated to the mass of the microsphere contained within the cell. Irregular shaped silica particles were also analyzed and a calibration curve was generated from these data.
