Study on the characteristics of superconducting bearing
IEEE International Magnetics Conference, 1999This paper deals with the experiments and simulations of the levitation force between permanent magnet and High Tc Superconductor (HTS), and also the simulations of the dynamic behaviors related to vibration. Levitation force is evaluated numerically on the basis of the magnetic vector potential method and the critical state model.

Germination Characteristics of Bear Oak
Southern Journal of Applied Forestry, 1977Abstract Freshly collected bear oak (Quercus ilicifolia Wangenh.) seed from southwestern Virginia exhibited root growth under a range of temperatures but had epicotyl dormancy which was broken by stratification or gibberellic acid (GA3).

CALCULATION OF THE CHARACTERISTICS OF GASOSTATIC BEARINGS
Технические и естественные науки: сборник избранных статей по материалам Международной научной конференции (Санкт-Петербург, Октябрь 2020), 2020Одной из важнейших характеристик задачи моделирования поведения шпиндельного узла является статическое давление газа в зазоре. Испытание газового слоя на статическую жесткость позволяет судить о качестве проектируемого ШУ и в некоторой степени о характере его поведения при динамических испытаниях.

Characteristics of Complement Receptor-Bearing Cells in the Spleens of Tumor-Bearing Mice
The Journal of Immunology, 1978Abstract In the course of mammary tumor development, a population of nylon nonadherent cells with CR appears in the spleens of tumor-bearing mice although none are ever detected in normal mice. These cells apparently arise in response to immunologic stimulation. In a series of studies we have further characterized subsets of T cells (CR+

Disposition Characteristics of Macromolecules in Tumor-Bearing Mice
Pharmaceutical Research, 1990As part of the strategy for the design of macromolecular carriers for drug targeting, the disposition characteristics of macromolecules were studied in mice bearing tumors that served as target tissues. Eight kinds of macromolecules including four polysaccharides and four proteins with different molecular weights and electric charges were used; tissue ...

Characteristics of a spindle bearing system with a gear located on the bearing span
International Journal of Machine Tools and Manufacture, 1997The spindle bearing system is the main source of the total cutting point compliance of machine tool structures. In this work, the static and dynamic characteristics of a spindle bearing system driven by a gear located on the bearing span were investigated using the analytical and finite element methods.

Load Bearing Characteristics of the Patello-Femoral Joint
Acta Orthopaedica Scandinavica, 1977This study of normal patello-femoral biomechanics defines some functional specifications which may be useful in future total knee prosthesis design. Serial lateral X-rays of 15 fresh knees and their patellar mechanisms at several flexion angles provided definition of the direction of the resolved patello-femoral forces.

Hair characteristics of four Indian bear species
Science & Justice, 2008Dorsal guard hairs of four species of bear (family: Ursidae) found in India were characterized using light microscopy by studying features including colour, hair thickness, cuticle pattern, medulla pattern, medullary index, cross-section and scale count index.

The wear characteristics of the oscillating bearing
Wear, 1961Abstract Oscillating bearing wear characteristics have been studied under uni-directional steady load conditions using hardened steel pins and bushes. The results are applicable to roller chain and other machine elements employing steel-to-steel oscillating bearing elements.
