Разработка дизайна оболочки велотренажера для людей с ограниченными физическими возможностями

Объектом исследования является велотренажер для людей с ограниченными физическими возможностями. Цель работы – проектирование оболочки велотренажера для людей с ограниченными физическими возможностями. В процессе проектирования проводилась разработка вариантов дизайнерских решений оболочки корпуса. В результате проектирования была разработана велотренажера для людей с ограниченными физическими возможностями.The object of the study is an exercise bike for people with disabilities. The aim of the work is to design the shell of an exercise bike for people with disabilities. In the design process, the development of variants of the design solutions of the hull shell was carried out. As a result of the design, an exercise bike was developed for people with disabilities

Measurement of the reaction gamma*p->phi p in deep, inelastic e(+)p scattering at HERA

The production of phi mesons in the reaction e(+)p --> e(+)phi p (phi --> K+K-), for 7 phi p cross section rises strongly with W. This behaviour is similar to that previously found for the gamma*p --> rho(0)p cross section. This strong dependence cannot be explained by production through soft pomeron exchange, It is, however, consistent with perturbative QCD expectations, where it reflects the rise of the gluon momentum density in the proton at small x. The ratio of sigma(phi)/sigma(rho(0)), which has previously been determined by ZEUS to be 0.065 +/- 0.013 (stat.) in photoproduction at a mean W of 70 GeV, is measured to be 0.18 +/- 0.05 (stat.) +/- 0.03 (syst.) at a mean Q(2) of 12.3 GeV2 and mean W of approximate to 100 GeV and is thus approaching at large Q(2) the value of 2/9 predicted from the quark charges of the vector mesons and a flavour independent production mechanism
