IMPROVING INFORMATION SUPPORT OF CRISIS MANAGEMENT BY ENTERPRISES ON THE BASIS OF USING COMMUNICATION TOOLS OF THE TECHNOLOGICAL PLATFORM

Information support of crisis management requires the creation of a communication infrastructure, based on the program-target method, within which technological standards and profiles are formed – technological platforms. The information support of the crisis management of enterprises, based on the use of communication tools of the technological platform, as an interface of the innovative infrastructure, allowing increase the efficiency of the information component of the enterprise management system, has been improved in the paper. Based on the technological platform, new research and production cooperations, innovation clusters will be formed, which will allow overcome the crisis state of enterprises

Structural features of Ni-Cr-Si-B materials obtained by different technologies

This study considers the structural features of Ni-Cr-Si-B (Ni - base; 15.1 % Cr; 2 % Si; 2 % B; 0.4 % C) materials obtained by different methods. The self-fluxing coatings were deposited by plasma spraying on the tubes from low carbon steel. Bulk cylinder specimens of 20 mm diameter and 15 mm height were obtained by spark plasma sintering (SPS). The structure and phase composition of these materials were investigated by optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffractometry (XRD). The major phases of coatings and sintered materials are [gamma]-Ni, Ni[3]B, CrB and Cr[7]C[3]. We demonstrate that the particle unmelted in the process of plasma spraying or SPS consist of [gamma]-Ni-NEB eutectic and also CrB and Cr[7]C[3] inclusions. The prolonged exposure of powder to high temperatures as well as slow cooling rates by SPS provide for the growth of the structural components as compared to those of plasma coatings materials. High cooling rates at the plasma spraying by melted particles contribute to the formation of supersaturated solid solution of Cr, Si and Fe in [gamma]-Ni. The structure of the melted particles in sintering material has gradient composition: the core constituted of Ni grains of 10 μm with [gamma]-Ni-Ni[3]B eutectic on the edges. The results of the experiment demonstrate that the sintering material has a smaller microhardness in comparison with plasma coatings (650 and 850 MPa, respectively), but at the same time the material has higher density (porosity less than 1 %) than plasma coatings (porosity about 2.. .3 %)

Investigation of the structure and microhardness of Mo-Fe-C coatings obtained by the electron beam injected in the atmosphere

In this work 'Mo-Fe-C' coatings fabricated on medium carbon steel by non-vacuum electron beam cladding were investigated. The structure of coatings and transition zones were studied by scanning electron microscopy (SEM). It was shown that an increase of Fe percentage in the cladding mixture led to a decrease of the eutectic volume fraction in the coating and was accompanied by the formation of the gradient structure between the coating and a substrate material. Measurements of microhardness in the cross section of samples revealed that the cladding of a 'Mo-C powder mixture contributed to a 4.5-fold increase of microhardness

Retrobulbar blockade during eyeball enucleation surgery in children with retinoblastoma

Retinoblastoma (RB) is a malignant tumor of the embryonic nerve retina.Purpose. To determine the effectiveness of retrobulbar blockade (RbB) with ropivacaine 0.5% for intra- and postoperative analgesia, as well as for the prevention of oculocardial reflex (OCR), postoperative nausea and vomiting (PONV) during enucleation.Material and methods. A prospective randomized controlled clinical trial was performed. Eighty patients aged 0 to 10 years were included, who were randomly assigned to the RbB group (retrobulbar blockade with ropivacaine 0.5% with general anesthesia) (n=40) and the GA control group (general anesthesia) (n=40).Results. There were no complications in the RbB group caused by the methodology. In the intraoperative period, the average dose of fentanyl in the RbB group was 4.7±0.7 μg/kg, which is significantly lower than in the OA group of 10.1±1.9 μg/kg (p<0.05). OCR in the RbB group was observed in 5% of cases versus 100% in the GA group (p=0.002). The average VAS score was 1.8 vs. 3.7 60 minutes after surgery (p<0.001). For the first time 12 hours after surgery, PONV was not observed in the RBB group, and in the control group it was observed in 45% of patients.Conclusion. The study revealed that intraoperative retrobulbar blockade with 0.5% ropivacaine solution in children with RB is effective and safe. Provides stable intraoperative hemodynamics and reduces the need for opioids. Promotes the prevention of OCD and PONV, as well as the improvement of postoperative analgesia during the operation of enucleation of the eyeball i n pediatric

ANALYSIS AND FORECASTING THE DYNAMICS OF ADVERTISING BOTS ACTIVITY

When introducing a new product or service to the market, a manufacturer or retailer is faced with the need to develop a promotion strategy. Taking into account the recent trends in e-commerce and social media marketing, it makes sense to evaluate the possibility of borrowing promotion strategies from producers of abstract, potentially  monetized electronic content. The article considers the activity of advertising bots using the example of the social network Facebook. The paper carries out an autocorrelation analysis of the observation results and reveals the frequency of automated requests to the user by advertising bots. The authors construct an autoregressive model of the dynamics of the activity of advertising bots and verbalize Facebook’s strategy to increase traffic to the  information space controlled by the social network

Peculiarities of self-diffusion of alkane molecules in kaolinite

Self-diffusion of alkanes in kaolinite has been explored by pulsed field gradient nuclear magnetic resonance. The concentration dependences of average self-diffusion coefficient (SDC) of liquid have been studied in the wide temperature interval (T=253-383 K). The translational mobility of alkane molecules in kaolinite was shown to have some specific peculiarities. An anomalous rise was found in the average self-diffusion coefficient of the liquid as its content in kaolinite decreased. To explain this we should introduce a new "gas-like" state for the diffusant, whose mobility exceeds that of pure liquid. The possibility of the existence of such a state is explained by kaolinite's ability to increase the specific surface area of the induced liquid. Analysis of a shape of the spin-echo diffusion attenuation leads one to suppose that there are heterogeneities in the medium's porous space. © 1991 Springer
