Social ecology: some conceptual and methodological aspects

Предметом социальной экологии становится анализ жизнедеятельности общественно-индустриального социума на определенном структурном уровне: поселенческом, городском, региональном. Базовой методологической структурой науки является социоэкосистема.The subject of social ecology is an analysis of the socio-industrial society on a structural level: settlement, city, regional. Basic methodological structure of these science is socioecosistema

Nanoparticles of Block Ionomer Complexes from Double Hydrophilic Poly(acrylic acid)-b-poly(ethylene oxide)-b-poly(acrylic acid) Triblock Copolymer and Oppositely Charged Surfactant

The novel water-dispersible nanoparticles from the double hydrophilic poly(acrylic acid)-b-poly(ethylene oxide)-b-poly(acrylic acid) (PAA-b-PEO-b-PAA) triblock copolymer and oppositely charged surfactant dodecyltrimethyl ammonium bromide (DTAB) were prepared by mixing the individual aqueous solutions. The structure of the nanoparticles was investigated as a function of the degree of neutralization (DN) by turbidimetry, dynamic light scattering (DSL),ζ-potential measurement, and atomic force microscope (AFM). The neutralization of the anionic PAA blocks with cationic DTAB accompanied with the hydrophobic interaction of alkyl tails of DTAB led to formation of core–shell nanoparticles with the core of the DTAB neutralized PAA blocks and the shell of the looped PEO blocks. The water-dispersible nanoparticles with negative ζ-potential were obtained over the DN range from 0.4 to 2.0 and their sizes depended on the DN. The looped PEO blocks hindered the further neutralization of the PAA blocks with cationic DTAB, resulting in existence of some negative charged PAA-b-PEO-b-PAA backbones even when DN > 1.0. The spherical and ellipsoidal nature of these nanoparticles was observed with AFM

MOVING PERSON IDENTIFICATION IN VIDEO SURVEILLANCE SYSTEMS

The paper deals with an approach for a moving person identifying in video surveillance systems. The proposed solution consists of two successive stages. Selecting of a moving human from all other moving objects in a video stream takes place at the first stage. Human identification based on facial image takes place at the second stage. Detection of a human’s movement is performed via representation of the original video stream in a form of time series. Mathematical apparatus of a singular spectrum is applied for that purpose. The presence of motion is determined by analyzing the periodic components of time series constructed from color and brightness data of the original components of initial video stream. Identification of a person based on his facial image is done through representation of a facial image via two-dimensional matrix with the subsequent application of immune computing mathematical apparatus. Then the binding energy is calculated which shows similarity between the input facial image and faces stored in the training set. The proposed solution for a problem of a moving person’s identifying gives the opportunity to work with low quality video stream having a high level of noise or compression artifacts after encoding. The advantage of the method is implementation simplicity. Unlike traditional methods of computer vision, the proposed method does not require significant computational burden due to simple numerical operations. This method does not require pre-filtering of video images, therefore its performance speed is significantly increased

CLINICAL, NEURO-PHYSIOLOGICAL AND NEURO-VISUAL ANALYSIS OF ADULT PATIENTS WITH FOCAL EPILEPSY AND ABNORMALITIES OF CARDIAC RHYTHM AND CONDUCTION IN THE ICTAL PERIOD

Objective. To conduct a survey of adult patients with focal epilepsy and ictal disturbances of cardiac rhythm and conduction, considering the disease classification, anamnesis, clinical, electroencephalographic and neuroimaging data.Materials and methods. We selected 70 patients aged 18 to 51 years old with confirmed diagnoses of focal epilepsy with epileptic seizures persisting at the time of the study on the background of antiepileptic therapy without concomitant cardiac disorders but with confirmed ictal changes in the cardiac rhythm and conduction.Results. Among the examined patients, those with long lasting “structural focal epilepsy”, frequent epileptic attacks, temporal and frontal-temporal epileptogenic foci, taking several antiepileptic drugs, prevailed. Most of the heart rhythm and conduction abnormalities occurred in male patients with serial paroxysms, bilateral tonic-clonic seizures, or sleep seizures.Сonclusion. The timely detection and examination of patients with high risk of ictal arrhythmias is able to prevent disturbances of cardiac rhythm and heart conduction during epileptic seizures, including those with a life-threatening potential
