The influence of different surface coatings of NiTi shape memory allays was examined using in vitro testing methods. Plates of superelastic nickel-titanium shape memory allay （ NiTi ） were coated with calcium phosphates （ hydroxyapatite ） by high-temperature plasma-spraying or by dip-coating. The biocompatibility was tested in vitro by cultivation of isolated human granulocytes and whole blood cells. As substrates, pure NiTi, plasma-spray-coated NiTi and dip-coated NiTi were used. Isolated granulocytes showed an increased adhesion to both calcium phosphate-coated NiTi samples. Compared to non-coated NiTi or dip-coated NiTi, the number of dead granulocytes adherent to plasma-sprayed surfaces was significantly increased （ p 〈 0.01 ）. Whether the d/f- ferences in apoptosis of granulocytes on dip-coated vs plasma-sprayed coatings observed are due to differences in material surface morphologies has to be analyzed in further studies. Because of the cellular interactions with the coating layers, h is likely that the results obtained are not caused by the underlying NiTi but due to the coating itself.

The paper dealt with quantum canonical ensembles by random walks, where state transitions are triggered by the connections between labels, not by elements, which are transferred. The balance conditions of such walks lead to emission rates of the labels. The labels with emission rates definitely lower than 1 are like modes. For labels with emission rates very close to 1, the quantum numbers are concentrated around a mean value. As an application I consider the role of the zero label in a quantum gas in equilibrium.

The fundamental protection principles of the new armours for main battle tanks against kinetic energy projectiles (KE) and chemical energy weapons (CE)--shaped charges are shortly described and their efficiency against both threats discussed. The armour topics can be split into: "perpendicular or zero-degree armours", such as rolled homogeneous armour (RHA), also with extremely high strength, ceramics, glass, liquid filled columns and explosive filled cells,"inclined armours", as spaced RHA plates with their corner effects, bulging armour, additive and integrated explosive reactive armours (ERA) and "hard kill active defence possibilities" in different defeating distances.

First the different anti-tank mines laying possibilities are shortly summarized: hand emplaced, with mine layers, ground or helicopter relatively topographical well defined, and with cluster systems of projectiles, rockets and aircraft dispensers. Then examples of the three generations of anti-tank mines are presented:Ⅰ generation: detonating only beneath the track; Ⅱ generation: detonating beneath the track and belly;Ⅲ generation: mines with off-route actions. Weight and cost comparisons are strongly favoring the off-route Ⅲ-generation mines.

Hens＇ eggs and corresponding feeds were sampled at commercial farms. The eggs were separated into egg yolk and egg white and freeze dried. After pressure digestion, total element contents of Ca, P, Mg, S, Na, Fe, Mn, Zn, Sr, Cu and Ba were detected by ICP-OES in the eggs, whereas, Pb, Ni, Sb, Sn, AI, Cd, Cr, Mo and V were all or largely below the detection limits. In addition, iodine was done by ICP-MS and Se after ashing with Mg-nitrate by hydride-generation-AAS. There were significant accumulations of P, S, Se and I in the egg yolk versus feed levels, as well as S and Na in the egg white. Just a few correlations between concentrations in feed and egg white resp. egg yolk were detected, indicating regulation mechanisms by homeostasis. Strontium showed the strongest trends between feeds and egg white and egg yolk, whereas, there was none for calcium. Among the main elements in the feeds, sulfur had the strongest effects on the egg compositions, e.g., on iodine and iron in the yolk and on sodium in the white, some of them might be non-linear.

Flowering pattern and seedling establishment of umbrella bamboo （Fargesia murieliae （Gamble） Yi） were studied in its native habitat, Mount Shennongjia in Central China. Here in 1996-2000, over 95% of the bamboo plants simultaneously flowered and died, extending from lower elevations to the higher mountains along the altitude and from southwest to northeast along the mountain settings. Bamboo seedlings emerged after the simultaneous flowering, achieving an average density of 5 460 seedlings·m^-2 in the autumn of the year following the flowering. After a high mortality throughout the first winter, bamboo seedlings remained a stable density in following 2-4 years （1130-1230 seedlings·m^-2）. Seedling density positively related to the coverage of parent bamboo, but negatively to the herb layers.

The bonding and electronic structure of Cu/(0001)Al2O3 and Cu/(1120)Al2O3 interfaces has been studied experimentally using spatially-resolved transmission electron energy loss spectroscopy. The specimen were prepared by depositing Cu on single-crystal α-AI2O3 substrates, which have been Ar+-ion sputter-cleaned prior to the growth of Cu. For both orientations of the α-Al2O3 substrate, atomically abrupt interfaces formed as determined by high-resolution transmission electron microscopy. The investigations of the interfacial Cu-L2,3, Al-L2,3 and 0-K energy loss near-edge structures, which are proportional to the site- and angular-momentum-projected unoccupied density of states above the Fermi level, indicate the existence of metallic Cu-AI bonds at the Cu/AI2O3 interface independent of the substrate orientation.
