Inhalation and peroral mucolytic therapy in mucoviscidosis in children

The paper summarizes the results of clinical studies of 98 children with mucoviscidosis whose age was 7 to 18 years. There is research evidence for possibility and expediency of using new classes of mucolytic agents in the therapy of mucoviscidosis in children. Analysis of the rheological properties of sputum showed the advantage of inhalation route of mucolytics over their oral administration. There is evidence for the advantage of mucosolvan over carbocysteine and unithiol via all routes of administration, the optimal methods of administration and differentiated indications have been developed.

Reserves for improving the utilization efficiency of regenerative extractions from turbines at cogeneration stations

It is shown that considerable reserves for improving energy efficiency are available at the majority of Russian cogeneration stations, because the arrangements using which heat is supplied for the needs of water treatment plants are far from being optimal. New solutions are proposed that allow heat to be supplied to these loads in a more economically efficient manner with the use of low-potential regenerative extractions from cogeneration steam turbines, as well as technologies for improving the efficiency of combined-cycle plants the exhaust gases from which are discharged into a boiler.     

A partial fuel reloading schedule for nuclear reactors

This paper considers the effect of partial reloading of the nuclear fuel on the degree of uranium burn-out in the working fuel rods of a reactor. The condition of minimum cost of electrical energy is used to find the optimum fraction of the nuclear fuel to be renewed periodically in the reactor. Here it is kept in mind that the reloading of fuel rods is done with the reactor shut down.The formulas for determining the optimum reloading fraction are derived for an infinite reactor lattice, with recovery of spent rods. The numerical results are found to be applicable to the reactors of the First Atomic Electric Station and the I. V. Kurchatov Beloyarskoe Atomic Electric Station.
