    Vector Rotators of Rigid Body Dynamics with Coupled Rotations around Axes without Intersection

    Vector method based on mass moment vectors and vector rotators coupled for pole and oriented axes is used for obtaining vector expressions for kinetic pressures on the shaft bearings of a rigid body dynamics with coupled rotations around axes without intersection. Mass inertia moment vectors and corresponding deviational vector components for pole and oriented axis are defined by K. Hedrih in 1991. These kinematical vectors rotators are defined for a system with two degrees of freedom as well as for rheonomic system with two degrees of mobility and one degree of freedom and coupled rotations around two coupled axes without intersection as well as their angular velocities and intensity. As an example of defined dynamics, we take into consideration a heavy gyrorotor disk with one degree of freedom and coupled rotations when one component of rotation is programmed by constant angular velocity. For this system with nonlinear dynamics, a series of tree parametric transformations of system nonlinear dynamics are presented. Some graphical visualization of vector rotators properties are presented too

    J. Inst. Brew. 116(4), 440-444, 2010 The possibility of producing a beverage by wort fermentation enriched with grape must was examined. Must, from two different varieties of grapes, was added to conventional brewer's wort. The fermentation was carried out using a traditional method for lager beer production with the entire process taking thirty days. Following the fermentation process, a sensory analysis of the final product was performed and the total polyphenol content was determined. The results obtained suggest that it is possible to produce a pleasant beverage with some sensory properties similar to conventional beer. In addition to acceptable sensory properties, this drink was characterized by a higher alcohol (7-7.5% v/v) and polyphenol content

    Plasma glucose, serum insulin and C-peptide were measured in patients with various stages of chronic renal failure (CRF). In this study we observed 50 patients: 26 women and 24 men, between the ages of 17 and 73. Following various stages of CRF our patients were devided into IV groups, with 10 patients in each. V-th group was control group with 10 healthy persons. Plasma glucose, serum insulin and C-peptide were measured in the fasting state and following the 2 hours oral glucose tolerance test (OGTT). In the fasting state, plasma glucose and serum insulin levels were normal in all groups. With deterioration of the renal function plasma glucose and serum insulin increased slower during OGTT but their levels also decreased slower. Fasting levels of C-peptide increased continually with deterioration of renal function in all patients and values were significantly higher than in control group

    Titanium and titanium alloys are widely used as materials for implants, because of their mechanical properties and nontoxic behaviour, but unfortunately, are bioinert. In order to solve this problem, the metal implant could be coated with bioactive materials with good adhesion to metal and could be also bonded interfacially to the bone. The aim of this work is to investigate the synthesis of functionally graded glass-apatite coating on Ti6A14V alloys by the electrophoretic method. In order to enhance bioactivity of the surface, nanostructured hydroxyapatite particles were embedded in the glass coating. The influence of synthesis condition such as deposition voltage and time on the coating properties and deposit weights were examined. It was shown that controlling the deposition voltage and time, the deposition weight and thickness of coating could be controlled. It was shown that electrophoretic deposition can be successfully employed for the preparation graded glass-apatite coating on Ti6A14V substrate

    The influence of hydrogenation on the biocompatibility of different hydroxyapatite (HAP) materials was tested. Materials consisted of pure HAP, HAP substituted with manganese (Mn+2) and with magnesium (Mg+2) - all axially pressed and conventionally sintered for 2 h at 1200 degrees C; pure HAP isostatic pressed and sintered by a microwave technique for 15 min at temperature of 1200 degrees C. Biocompatibility was compared by enumeration of the number of osteoblast-like cells to the materials before and after hydrogenation. Obtained results show that the osteoblastic cells demonstrated a higher ability to attach to HAP if its surface was negatively charged. Hydrogenation altered the surface potential; HAP substituted with manganese - HAP(Mn) and with magnesium - HAP(Mg) demonstrated the highest ability to engineer the charge

    In this paper the synthesis of bioactive cement based on al-Ca-3(PO4)(2) (a-TCP) and calcium deficient hydroxyapatite (CDHAp), obtained by hydrothermal method from CaCl2, EDTA, NaH(2)PO(4)(.)12H(2)O and urea at 160 degrees C, was described. According to the results of DTA, SEM, X-ray and FTIR analyses performed in this investigation, it is shown that CDHAp is transformed to beta-TCP at 780 degrees C, and to a-TCP at 1400 degrees C. The hardening of the samples, prepared from the mixture of alpha-TCP and 2.5 % solution of Na2HPO4, in simulated body fluid at 37 degrees C, was followed by the microstructure changes

    Starting from two microspherical agglomerated HAP powders, porous biphasic HAP/TCP bioceramics were obtained by microwave sintering. During the sintering the HAP powders turned into biphasic mixtures, whereby HAP was the dominant crystalline phase in the case of the sample with the higher Ca/P ratio (HAP1) while alpha-TCP was the dominant crystalline phase in the sample with lower Ca/P ratio (HAP2). The porous microstructures of the obtained bioceramics were characterized by spherical intra-agglomerate pores and shapeless inter-agglomerate pores. The fracture toughness of the HAP1 and HAP2 samples microwave sintered at 1200 A degrees C for 15 min were 1.25 MPa m(1/2). The phase composition of the obtained bioceramics only had a minor effect on the indentation fracture toughness compared to a unique microstructure consisting of spherical intra-agglomerate pores with strong bonds between the spherical agglomerates. Cold isostatic pressing at 400 MPa before microwave sintering led to an increase in the fracture toughness of the biphasic HAP/TCP bioceramics to 1.35 MPa m(1/2)
