Physical properties of metal nanoparticle are very strongly differ more often from properties of volume samples of the same stuff (for example, reduction of the dimensions of a particle leads to reduction of its fusion temperature). Technologists have learnt to make nanoparticles the various dimensions, the form and a chemical compound. And here to monitor number and phylum of defects in nanoparticles they are not able yet. Therefore in a question on influence of defects on characteristics nanoparticle till now there are many white maculae. Meanwhile it is known, that presence of defects can lead to rather essential change of properties nanoparticles. For example, defective golden nanoparticles are more stable thermodynamically.

Nanous galaxy NGC 5253 observation of in neutral hydrogen (21 cm) line has been spent on radio telescopes VLA and Parkes 64м. It is found nonaxisymmetric allocation of the neutral hydrogen which lump compounds 1.4 x 108 masses of the Sun.

 The old age is not illness, however with the years in an organism variety of characteristic changes which gradually enlarge a distance between older persons and a young organism is observed. It concerns not only choronomic implications, but also function of organs and tissues variety. The science studying patterns of ageing processes  is called as gerontology.

 Bronchial asthma is extremely hazardous disease of the allergic nature. We already told about it. We will remind that the bronchial asthma is characterised by periodic appearance in the person of coughing fits and an expiratory dyspnea that is the expiration of air from lungs strongly worsens, that negatively affects saturation rate of blood oxygen, on work of the vital organs and an organism as a whole. Especially it is necessary to note gravity of the bronchial asthma arising in the early childhood. Many allergists notice that the earlier child will be ill with this disease, the more hardly it proceeds at mature age.
