We analyze the production of φ mesons in πN and N N reactions in the nearthreshold region, using throughout the conventional "non-strange" dynamics based on such processes which are allowed by the non-ideal ω − φ mixing.We show that the occurrence of the direct φN N interaction may show up in different unpolarized and polarization observables in πN → N φ reactions.We find a strong non-trivial difference between observables in the reactions pp → ppφ and pn → pnφ caused by the different role of the spin singlet and triplet states in the entrance channel. A series of predictions for the experimental study of this effect is presented.

We estimate the contribution of f 2 trajectory exchange to the central η and η ′ production. It is shown that secondary Reggeons may give a large contribution to processes of double diffractive meson production at high energies.PACS number(s): 12.40.Nn, 13.60. Le, 12.39.Mk

The ρ − ω interference in the exclusive reaction πN → N ′ e + e − is studied within a schematic model including the established baryon resonances up to 1720 MeV. Near threshold the interference can be used to separate the isoscalar part of the electromagnetic current. The role of various baryon resonances is highlighted.

Проблема получения достоверных оценок показателей производства в судостроении, основополагающим из которых является показатель трудоёмкости, обусловлена требованиями системного подхода и особенностями производства больших технических систем – судов. Разнообразие методологических и методических подходов, номенклатура конструктивно-технологических параметров, используемых в настоящее время для получения оценок трудоёмкости, приводит к появлению значительных систематических и случайных погрешностей. Потребность создания многоуровневой взаимосвязанной системы дискретных оценок показателей трудоёмкости, снижение погрешности оценок - актуальная задача, решение которой позволяет планировать и достоверно прогнозировать развитие судостроительного производства адекватно условиям выполнения работ. В статье изложены дополнительные подходы при разработке моделей оценки трудоёмкости, обеспечивающие достоверность, низкую установочную систематическую погрешность, возможность получения оценок, начиная с ранних этапов технической подготовки производства и включая выполнение работ. The problem of obtaining reliable estimates of production indicators in shipbuilding, the fundamental of which is the indicator of labor intensity, is due to the requirements of a systematic approach and the specifics of the production of large technical systems - ships. A variety of methodological and methodological approaches, the range of design and technological parameters currently used to obtain estimates of labor intensity, leads to the appearance of significant systematic and random errors. The need to create a multi-level interconnected system of discrete estimates of labor intensity indicators, reducing the error of estimates is an urgent task, the solution of which allows planning and reliably predicting the development of shipbuilding production adequately to the conditions of work. The article presents additional approaches to the development of models for estimating labor intensity, providing reliability, low installation systematic error, the possibility of obtaining estimates, starting from the early stages of technical preparation of production and including the execution of work.
