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.

based on fundamental research, we developed the basic scheme of a decontamination setup to remove acid gases (HCl, SO2, NOx) from steam-air flows with simultaneous localization of radioactive aerosols, including aerosols with a particle size of less than 0.1 μm and volatile radioactive iodine compounds. The decontamination process is based on the method of the agglomeration cocrystallization of finely dispersed and other aerosols in the gas phase by including the aerosols in the inner structure of large-particle non-radioactive aerosols of ammonium salts, for example, NH4Cl or (NH4)2SO3. For 137Cs, the most ecologically dangerous long-lived radionuclide, the setup ensures a decontamination factor of 102 to 103 in one decontamination stage. because the setup consists of three consecutive stages of the same type, the cumulative decontamination factor can reach to 106 - 107. To localize radioactive iodine as I2, HI, HOI, HIO3, and CH3I from vapor-air flows, the setup uses a unit containing special granulated sorbents based on inorganic compounds. Developed at the Institute of Physical Chemistry, Russian Academy of Sciences, these sorbents effectively remove various radioactive iodine species (inorganic species and methyl iodide) from steam-air flows, ensuring decontamination factors of at least 104. The proposed technological scheme will allow vapor-gas flows to be cleaned of radioaerosols and all volatile radioactive iodine species at decontamination factors of not less than 104.

The basic methods of concentration and purification of liquid radioactive waste on the nuclear power plant are distillation and ionic exchange. During vaporization of oil waste products and the fulfilled washing solutions the part of oil passes into a condensate. Clearing of such condensate on ion-exchanged filters results to oiling of ion-exchanged materials and to decrease number of filter cycles. Due to the often regeneration of ion-exchanged filters additional volumes of waste products as the fulfilled reclaiming solutions, washing and loosening waters are formed. The attention of scientists was involved with methods of clearing of water environments from the organic substances, based on deep oxidizing transformations of hydrocarbons into carbonic gas and water. From processes of oxidation of hydrocarbons up to CO2 and H2O, sold at moderate conditions, our attention has involved photochemical oxidation with the help of UV-radiation.

background: Nursing practice has to contribute to evidence pointing out why there is a need for more nurse-designed randomized control trials (RCTs) focusing on evidence-based practice (EbP). How far this EbP has progressed in different health aspects is usually established by systematic reviews of RCTs. Nurse-led RCTs exist but no study has addressed the essentials of nursing care. Aim: The aim was therefore to determine the essentials of nurses’ interventions by means of nurse-led RCTs in somatic care focusing on the stated context, goals, content, strategies as well as the nurse’s role related to effectiveness. Methods: A systematic review was realized according to Cochrane review assumptions to identify, appraise and synthesize all empirical evidence meeting pre-specified eligibility criteria. The PRISMA statement guided the data extraction process (n = 55) from PubMed and CINAHL. Results: Of the RCTs in somatic care, 71% showed a positive effectiveness of nurse-led interventions, of which the nurse had a significant role with regard to being the main responsible in 67% of the studies. Also, 47% of the RCTs presented a theoretical standpoint related to the nurse-led interventions and most prominent were international evidence-based guidelines. Goals were found to have either a patient-centered or a professional-centered ambition. Strategies were based on patient-directed initiatives, nurse-patient-directed initiatives or nurse-directed initiatives, while contents were built upon either a patient-nurse interaction or a nursing management plan. Conclusions: This review underlines the necessity of a holistic view of a person, as nurse-led RCTs comprising a patient-centered ambition, patient-directed initiative and patient-nurse interaction plan showed beneficial nursing care effectiveness, particularly if theory-based. In a nurse-led RCT, a basic theoretical perspective is advantageous as well as to elucidate the role of the nurse in relation to the estimated effec

Potentials range is determined in which the cobalt-tungsten alloy phase selectively dissolved in solutions of phosphoric acid to form soluble compounds of these metals, while the tungsten carbide phase remains in the precipitate. It shows that tungsten ores and concentrates are decomposed at 1,050℃-1,100℃ in sodium chloride-sodium metasilicate melts to form two immiscible phases, namely, halide-tungstate, containing 96% to 99% of tungsten, and silicate, containing 90% of the rest ore components.

动态流域模型HbV-N通过增加磷输送的程序已得到进一步开发,现被称为HbV-NP模型。现已证明,该模型能够令人满意地模拟伦讷(Rnnea)河流域(1900km^2)的营养动力学。检验了该模型对输入数据的敏感性,结果证实,与流域尺度相比,在子流域尺度上,其对输入数据的选择的敏感性提高。在某些子流域,土壤和土地利用数据库的选择被认为是关键的,但在流域水平则没有显著的影响。尽管对点源和农村家庭排放的污染物采用样板和概括的方法在流域尺度上是可以接受的,但与利用更详细的当地信息相比,这种方法则显著地降低了该模型在某些子流域的性能。把流域分成64个子流域的做法对在流域出口处产生的模型性能与集总做法的效果类似。根据子流域水的平均渗滤量调整地区农田氮淋溶的输入矩阵对模型性能不会产生显著的影响。
