Manipulative techniques in political election campaign advertising: experience of Ukraine (Маніпулятивні прийоми у політичній передвиборчій рекламі: досвід України)
The article embraces the scope of the techniques used in manipulation of public opinion by candidates in the election process of Ukraine during the period of 2004-2012. The main focus is on the political election campaign advertising, revealing its meaning as communicative activity and as a process that mostly always is accompanied by the use of manipulative techniques. Based on the author's analysis of election campaigns and works of Ukrainian scholars, there were also determined manipulative methods and techniques that were most actively used during the last election cycles (У статті розкрито особливості використання прийомів маніпуляції суспільною свідомістю суб’єктами виборчих процесів в Україні у 2004-2012 рр. Основна увагу зосереджено на політичній передвиборчій рекламі; розкривається її зміст як комунікативної діяльності та процесу, який фактично завжди супроводжується використанням маніпулятивних технологій. На основі авторського аналізу виборчих кампаній та праць українських вчених, визначено маніпулятивні методики та прийоми, які найактивніше використовувалися під час останніх виборчих циклів
Frequency-Domain Coherent Control of Femtosecond Two-Photon Absorption: Intermediate-Field vs. Weak-Field Regime
Coherent control of femtosecond two-photon absorption in the
intermediate-field regime is analyzed in detail in the powerful frequency
domain using an extended 4th-order perturbative description. The corresponding
absorption is coherently induced by the weak-field non-resonant two-photon
transitions as well as by four-photon transitions involving three absorbed
photons and one emitted photons. The interferences between these two groups of
transitions lead to a difference between the intermediate-field and weak-field
absorption dynamics. The corresponding interference nature (constructive or
destructive) strongly depends on the detuning direction of the pulse spectrum
from half the two-photon transition frequency. The model system of the study is
atomic sodium, for which both experimental and theoretical results are
obtained. The detailed understanding obtained here serves as a basis for
coherent control with rationally-shaped femtosecond pulses in a regime of
sizable absorption yields.Comment: 25 pages, 5 figure
Transient dynamics of nonlinear magneto-optical rotation
We analyze nonlinear magneto-optical rotation (NMOR) in rubidium vapor
subjected to continuously-scanned magnetic field. By varying magnetic-field
sweep rate, a transition from traditionally-observed dispersive-like NMOR
signals (low sweep rate) to oscillating signals (higher sweep rates) is
demonstrated. The transient oscillatory behavior is studied versus light and
magnetic-field parameters, revealing a strong dependence of the signals on
magnetic-sweep rate and light intensity. The experimental results are supported
with density-matrix calculations, which enable quantitative analysis of the
effect. Fitting of the signals simulated versus different parameters with a
theoretically-motivated curve reveals presence of oscillatory and static
components in the signals. The components depend differently on the system
parameters, which suggests their distinct nature. The investigations provide
insight into dynamics of ground-state coherence generation and enable
application of NMOR in detection of transient spin couplings.Comment: 9 pages, 7 figures, Submitted to Physical Review

The southern Darwin's frog, R. darwinii, is found in the temperate forests of southern South America, is listed as Endangered and could be the only extant representative of this genus. Based on stomach contents, invertebrate prey availability and stable isotope analysis, we determined for the first time trophic ecological parameters for this species. Our results showed that R. darwinii is a generalist sit-and-wait predator and a secondary consumer, with a trophic position of 2.9. Carbon and nitrogen isotope composition indicated that herbivore invertebrates are their main prey, detected in 68.1% of their assimilated food. The most consumed prey included mosquitoes, flies, crickets, grasshoppers and ants. Detritivore and carnivore invertebrates were also ingested, but in lower proportions. Our results contribute to a better understanding of the feeding habits of this fully terrestrial amphibian and provide the first insight into their role linking low forest trophic positions with intermediate predators. We provide valuable biological information for in situ and ex situ conservation which can be used when developing habitat protection, reintroduction and captive breeding programmes. As revealed here, stable isotope analysis is a valuable tool to study the trophic ecology of highly endangered and cryptic species. © The authors 2018.https://www.int-res.com/abstracts/esr/v36/p269-278
The use of autologous bone grafts and xenogenic bone materials for reconstruction of the facial bone defects (randomized prospective study)
The objective - to compare the efficacy of surgical interventions to replace jaw defects with the use of different types of bone grafts based on objective clinical and radiological criteria. The study included 90 patients with postoperative jaws defects. They underwent reconstructive operation for creating conditions for further prosthetic rehabilitation. The patients were divided into 3 randomized groups, depending on the surgical treatment used: group I - xenogenic bone substitutes were used, group II - autologous corticocancellous bone grafts from the iliac crest and in group III autograft combined with PRGF. Patients' status was assessed in the early (up to 1 month) and long-term postoperative period (more than 6 months). In the study series, xenogenic materials showed the highest volumetric stability in the remote postoperative period (19,9 ± 8,1% versus 45.6 ± 21.84% for bone autografts). However, autologous grafts demonstrated better integration and quality of bone tissue. There were no significant differences in frequency of postoperative complications or the possibility of implant placement in the study groups. The use of PRGF in combination with autograft accelerated the regeneration of soft tissues, but it does not affect significantly the incidence of infection complications and volume loss of the bone grafts
Gastro-Esophageal Reflux in Children
Gastro-esophageal reflux (GER) is common in infants and children and has a varied clinical presentation: from infants with innocent regurgitation to infants and children with severe esophageal and extra-esophageal complications that define pathological gastro-esophageal reflux disease (GERD). Although the pathophysiology is similar to that of adults, symptoms of GERD in infants and children are often distinct from classic ones such as heartburn. The passage of gastric contents into the esophagus is a normal phenomenon occurring many times a day both in adults and children, but, in infants, several factors contribute to exacerbate this phenomenon, including a liquid milk-based diet, recumbent position and both structural and functional immaturity of the gastro-esophageal junction. This article focuses on the presentation, diagnosis and treatment of GERD that occurs in infants and children, based on available and current guidelines
