We report on the design and performance of a fiber laser system with adaptive acousto-optic macropulse control for a novel photocathode laser driver with 3D ellipsoidal pulse shaping. The laser system incorporates a threestage fiber amplifier with an integrated acousto-optical modulator. A digital electronic control system with feedback combines the functions of the arbitrary micropulse selection and modulation resulting in macropulse envelope profiling. As a benefit, a narrow temporal transparency window of the modulator, comparable to a laser pulse repetition period, effectively improves temporal contrast. In experiments, we demonstrated rectangular laser pulse train profiling at the output of a three-cascade Yb-doped fiber amplifier.

We consider plus-operators in Krein spaces and generated operator linear fractional relations of the following form: . We study some special type of factorization for plus-operators T, among them the following one: T = bU, where b is a lower triangular plus-operator, U is a J-unitary operator. We apply the above factorization to the study of basical properties of relations (1), in particular, convexity and compactness of their images with respect to the weak operator topology. Obtained results we apply to the known Koenigs embedding problem, the Krein-Phillips problem of existing of invariant semidefinite subspaces for some families of plus-operators and to some other fields.

The study of green mass nutritional value of the black poplars euramerican hybrids-Populus euramericana (Dode) Guinier was conducted. The content of fodder units, digestible and crude protein, crude fat, fiber, ash, nitrogen, calcium, phosphorus, carotene and others was studied. The study showed that the leaves had greater nutritional value than stems and branches. The fresh leaves collected from the annual shoots of trees were more nutritious than annual coppice shoots of reproductive plantations but after drying the nutritional value of the materials became similar. Indicators of stems nutritional value were similar to those of wheat straw and those of leaves that were close to the nutritional value of alfalfa. Nutritional value of leafy shoots was intermediate between that of stems and leaves. Young coppice plant material is much easier to harvest than that of mature trees. Minirotation cultivation of poplars allows obtaining significant reserves of both wood and leafing biomass in a short period of time per unit area. The "old clones" of euramerican hybrids of black poplars are more winter resistant than some southern poplars of Italian breeding. This allows cultivating them not only in places of habitual areas of poplars, but also in more Northern regions.

Here the authors critically review the IPCC"s claim that global warming is "very likely" caused by human activity: such a description underestimates the likelihood of the warming being due to this mechanism. Next examined are known alternative "natural" mechanisms which could give rise to the warming if, despite many claims, the man-made explanation was false because of compensation effects (greenhouse gases versus aerosol effects). Also, a number of difficulties, as yet unresolved, in the human-induced warming explanation are considered.

The report presents a validated strategy of implementation of fast reactors SVbR-100 in nuclear power, which provides putting in operation the reactors using the mastered uranium oxide fuel with postponed reprocessing and changing over to the closed fuel cycle with use of the own spent fuel. by the end of the lifetime, a comparatively high core breeding ratio (~0.84) of reactor SVbR-100 using uranium oxide fuel for operation provides high content of plutonium in the spent nuclear fuel, which could be used in next fuel lifetimes while organizing the closed fuel cycle. That strategy is more economically efficient as the amount of reprocessing in terms of 1 t of plutonium is approximately 10 times less than the corresponding amount of plutonium extracted from the spent nuclear fuel of thermal reactors. Such approach to organization of the fuel cycle will reduce considerably the integral consumption of natural uranium and regarding to this, it will make NPPs based on reactors SVbR-100 competitive with NPPs based on thermal reactors. The report also reveals that in the closed nuclear fuel cycle instead of pile (depleted) uranium, the spent fuel of thermal reactors without separating of uranium, plutonium, minor actinides and fission products can be used as makeup fuel similarly to the DUPIC-technology for reactors CANDU.
