Sociocultural aspect of realization of civil control in modern Russian society

The backwardness of civil control in modern Russia is connected with a complex of the reasons of sociocultural character, including with specifics of the Russian traditions of public participation. It is proved that only collective forms of civil control relying on mobilization and use of the social capital of local communities can be the most effective in Russi

Kinetics of exciton photoluminescence in type-II semiconductor superlattices

The exciton decay rate at a rough interface in type-II semiconductor superlattices is investigated. It is shown that the possibility of recombination of indirect excitons at a plane interface essentially affects kinetics of the exciton photoluminescence at a rough interface. This happens because of strong correlation between the exciton recombination at the plane interface and at the roughness. Expressions that relate the parameters of the luminescence kinetics with statistical characteristics of the rough interface are obtained. The mean height and length of roughnesses in GaAs/AlAs superlattices are estimated from the experimental data.Comment: 3 PostScript figure

Bose--Einstein solitons in highly asymmetric traps

We obtain analytic solutions to the Gross-Pitaevskii equation with negative scattering length in highly asymmetric traps. We find that in these traps the Bose--Einstein condensates behave like quasiparticles and do not expand when the trapping in one direction is eliminated. The results can be applicable to the control of the motion of Bose--Einstein condensates.Comment: 12 pages, Latex, Figures available under request on [email protected]

Extended parametric resonances in nonlinear Schrodinger systems

We study an example of exact parametric resonance in a extended system ruled by nonlinear partial differential equations of nonlinear Schr\"odinger type. It is also conjectured how related models not exactly solvable should behave in the same way. The results have applicability in recent experiments in Bose-Einstein condensation and to classical problems in Nonlinear Optics.Comment: 1 figur

Концептуальний підхід до процесу формування конкурентних переваг підприємства на засадах адаптивного управління

У статті на основі аналізу та узагальнення низки наукових досліджень уточнено зміст понять "конкуренція" та "конкурентоспроможність підприємства". Досліджено актуальність проблем конкуренції і втрати конкурентоспроможності підприємствами в умовах поглиблення та розповсюдження наслідків економічних криз. Проаналізовано й узагальнено погляди на трактовку понять "адаптація" та "адаптивне управління промисловими підприємствами", обґрунтовано необхідність для сучасних підприємств застосовувати у процесах управління різні способи адаптації. Запропоновано концепцію формування конкурентних переваг підприємства на засадах адаптивного управління, в основу якого покладено комплексний динамічний підхід, досліджено взаємозв’язок принципів адаптивності, системності, гнучкості, ефективності, взаємозв’язку, адекватності й керованості із можливістю розвитку конкурентних переваг підприємства. Завданням концепції відповідає застосування адаптивних інтегрованих систем; системи планування ситуації в галузі і адаптивної системи регулювання; розробка очікуваних показників конкурентних переваг підприємства і відхилень від них; моделювання адаптивного реагування на зміни в реальній економічній системі. Дана концепція дозволяє здійснювати процес управління конкурентними перевагами з максимальною ефективністю за рахунок чутливого реагування як на зовнішні непередбачувані зміни в галузі, так і внутрішні потенційні зміни на підприємстві. Проведено аналіз сучасних динамічних умов функціонування промислових підприємств України, виявлено низку зовнішніх та внутрішніх проблем, серед яких несприятливий інвестиційний клімат, необхідність відповідати досягненням науково-технічного прогресу (з широким впровадженням прогресивних технологій) та відсутність стратегії господарювання за мінливих ринкових умов. Доведено, що для промислових підприємств сьогодні застосування принципів адаптивного управління є вирішальним фактором досягнення ними стійкої конкурентоспроможності на ринку паливної енергетики, що є однією із стратегічних задач створення ефективної системи управління на підприємствах, яка б забезпечувала їм стійкі конкурентні переваги.In the paper based on research and generalization of many separate scientific studies, the content of the concepts of "competition" and "competitiveness of the enterprise" is formed. The actuality of the problems of competition and loss of competitiveness of enterprises in the conditions of deepening and spreading of consequences of economic crises, which suppress practically all branches of industry and economy of Ukraine, is revealed. The views on the interpretation of the concepts of adaptation and adaptive management by industrial enterprises are analysed and summarized, and the necessity for modern enterprises to apply different methods of adaptation in management processes is grounded. The concept of formation of competitive advantages of the enterprise on the principles of adaptive management is proposed, based on the complex dynamic approach, the interrelation of the principles of adaptability, flexibility, efficiency, interconnection, adequacy and controllability with the possibility of development of competitive advantages of the enterprise is investigated. The task of the concept corresponds to the application of adaptive integrated systems; system planning in the industry and adaptive regulation system; development of expected indicators of competitive advantages of the enterprise and deviations from them; modelling adaptive response to changes in the real economic system. This concept allows the process of managing the competitive advantages with the maximum efficiency due to the sensitive response both to external unpredictable changes in the industry and internal potential changes in the enterprise. An analysis of the current dynamic conditions of the functioning of industrial enterprises has been carried out, a number of external and internal problems have been identified, including unfavourable investment climate, the need to match the achievements of scientific and technological progress (with the widespread introduction of advanced technologies) and the lack of a management strategy in changing market conditions. It is proved that for industrial enterprises, the application of the principles of adaptive control as a competitive advantage is a decisive factor in achieving their sustainable competitiveness in the market of fuel energy, which is one of the strategic tasks of creating an effective system of management at enterprises that would provide them stable

ANALYSIS OF THE EFFICIENCY OF PRECISION ENDO-LASER COAGULATION IN PATIENTS WITH PROLIFERATIVE DIABETIC RETINOPATHY USING INTRAOPERATIVE FLUORESCEIN ANGIOGRAPHY

Purpose. To analyze the efficacy of the initial precision retinal endolaser coagulation during subtotal vitrectomy in patients with proliferative diabetic retinopathy (PDR) complicated by intraocular hemorrhage, using intraoperative fluorescein angiography (FAG).Material and methods. The study included 55 patients (61 eyes). All patients were divided into 2 groups: in the group I (24 patients, 29 eyes) endo-laser coagulation of the retina was performed based on intraoperative fluorescein angiography results; patients of the group II (31 patients, 32 eyes) endo-laser coagulation of the retina was performed without angiography data.Results. According to the FAG, carried out after 3 months, areas of hyper-fluorescence in peripheral parts of the retina outside the area of retinal photocoagulation were revealed in the groups I and II (in 4 eyes (20%) and 12 eyes (60%), respectively) as well as macular edema (1 eye (5%) and in 6 eyes (30%), respectively). The computer perimetry detected an absolute scotoma in the laser coagulation area in 28 cases (45.9%), outside the laser coagulation sites – in 30 cases (49.2%), outside and inside the laser coagulation zone – in 1 case (1.6%), and tubular vision – in 2 cases (3.3%).Conclusion. The intraoperative FAG application allowed to perform the endo-laser coagulation of the retina under a dosed control. This technique allows to optimize and reduce the number of coagulates and thus to avoid complications associated with laser treatment, to avoid the damage of intact retina and to preserve the peripheral vision

EFFECT OF SURGICAL TREATMENT OF PATIENTS WITH PROLIFERATIVE DIABETIC RETINOPATHY COMPLICATED BY HEMOPHTHALMIA

Purpose: to analyze the effectiveness of endolaser retina photocoagulation and subtotal vitrectomy in patients with proliferative diabetic retinopathy complicated by hemophthalmos using intraoperative fluorescein angiography. Patients and methods. Patients were divided into two groups. In the main group (24 patients, 29 eyes) we performed endolaser photocoagulation of the retina using intraoperative fluorescein angiography data after removal of the altered vitreous body. In control group (31 patients, 32 eyes) we performed endolaser photocoagulation after the altered vitreous body removal in the zones of suspected ischemia without data of fluorescein angiography. Conclusions about the effectiveness of therapy were based on improvement / decrease of visual acuity, intraocular pressure dynamics, electrophysiological studies data and the number of complications (recurrent hemophthalmos, increased intraocular pressure, macular edema and iatrogenic scotomas). Results. The study was conducted on 61 eyes of 55 patients (age 23–80 years, male/female ratio was 0,53). Visual acuity before the operative intervention was 0.001 (median). Visual acuity in the main group was 0.3 (vs 0.1 in the control group) in one month after surgery, 0.35 — after 3 months and 0.3 — after 6 months (vs 0.1 and 0.2 in the control group, respectively). The sensory threshold in the control group (100 μA) was significantly higher than in the main group (90 μA). The incidence of hemophthalmos was significantly lower in the main group compared with the control (6.9% in the main group vs 31.3% in the control group). The incidence of absolute scotomas in the laser photocoagulation zone was significantly higher in the main group (100.0% vs 6.3%), and the incidence of absolute scotomas outside the laser photocoagulation zone was significantly higher in the control group in comparison with the main group (100.0% vs 3.4%). Conclusion. Endolaser photocoagulation in the target non-perfused retinal areas according to intraoperative fluorescein angiography data effectively increases visual acuity at 1, 3 and 6 months after surgery and reduces the number of complications such as hemophthalmos, development of iatrogenic absolute scotomas outside the laser coagulation zone
