Addiction Science & Clinical Practice , 2013, DOI: 10.1186/1940-0640-8-1
Abstract: The paper describes the intervention protocol and addresses questions about the feasibility of a brief FASD prevention intervention delivered by OB/GYN at women's clinics in Russia. Brief physician intervention guidelines and two evidence-based FASD prevention interventions were utilized to design a brief dual-focused physician intervention (DFBPI) appropriate to Russian OB/GYN care. The questions answered were whether trained OB/GYN physicians could feasibly deliver DFBPI during women's routine clinic visits, whether they maintained skills over time in clinical settings, and which specific intervention components were better maintained. Data were collected as part of a larger study aimed at evaluating effectiveness of DFBPI in reducing AEP risk in non-pregnant women. Methods of monitoring the intervention delivery included fidelity check lists (FCL) with the key components of the intervention completed by physicians and patients and live and audio taped observations of intervention sessions. Physicians (N= 23) and women (N= 372) independently completed FCL, and 78 audiotapes were coded.The differences between women's and physicians' reports on individual items were not significant. Although the majority of physician and patient reports were consistent (N=305), a discrepancy existed between the reports in 57 cases. Women reported more intervention components missing compared to physicians (p<0.001). Discussing barriers was the most difficult component for physicians to implement, and OB/GYN demonstrated difficulties in discussing contraception methods.The results supported the feasibility of the DFBPI in Russia. OB/GYN physicians trained in the DFBPI, monitored, and supported were able to implement and maintain skills during the study. In addition to the alcohol focus, DFBPI training needs to have a sufficient component to improve physicians' skills in discussing contraception use.

S. Tsvetkova
Venets : The Belogradchik Journal for Local History, Cultural Heritage and Folk Studies , 2012,
Abstract: “Homeland” is a cycle of poems dedicated to Belogradchik and the district. These poems have already been published in a recent Tsvetkova’s book “I Am Yantra” (Varna, 2012). Stefka Tsvetkova grew in a family of the teacher Tsvetko Stoyanov; her mother is also a teacher, and it is the reason for her to live and study in Belogradchik, Lom, Oreshets, Karbintsi, Varbovchets, Alexandrovo and Gyurgich. To write her poems Tsvetkova was inspired from these places and their people.
Some results of geochemical research in the Western Caucasus during the regional earthquakes  [PDF]

Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.58A1002

Results of geochemical researches in the Western Caucasus (South Russia) during the regional earthquakes are described. Monthly soil Rn data do not correlate with earthquakes. Daily concentrations of Rn in galleries, caves, mud volcanoes and faults increase before earthquakes and decrease after them. “Splashes” about 9 days before earthquakes in the hourly Rn data are found out. Similar “splashes” were observed in the data of a gamma background in galleries and the Earth’s surface. Concentration of CO2 in underground water was increasing more often after an earthquake. Concentration of Rn in the water was increasing before earthpquake. Strong sine wave daily variations of the soil H2 decreased during earthquakes. Concentration of some chemical elements in underground waters changed similarly Rn data before earthquakes.

Language specificity of the texts of political speeches of Angela Merkel
Tsvetkova E. B.
Vestnik Immanuel Kant Baltic Federal University , 2013,
Abstract: This article discusses the concept of discourse, its special form political discourse, the verbal behavior of German Chancellor Angela Merkel, especially her ability to put into practice different speechmeans in political communications. It focuses on the analysis of the linguistic-stylistic and pragmalinguistic resources realized in the texts of her political speeches. In this article is discovered a new tactic called "tactic of pickup statements minded / opponents."
The Social Contagion of Generosity
Milena Tsvetkova, Michael W. Macy
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0087275
Abstract: Why do people help strangers when there is a low probability that help will be directly reciprocated or socially rewarded? A possible explanation is that these acts are contagious: those who receive or observe help from a stranger become more likely to help others. We test two mechanisms for the social contagion of generosity among strangers: generalized reciprocity (a recipient of generosity is more likely to pay it forward) and third-party influence (an observer of generous behavior is more likely to emulate it). We use an online experiment with randomized trials to test the two hypothesized mechanisms and their interaction by manipulating the extent to which participants receive and observe help. Results show that receiving help can increase the willingness to be generous towards others, but observing help can have the opposite effect, especially among those who have not received help. These results suggest that observing widespread generosity may attenuate the belief that one’s own efforts are needed.
Interaction of Coal Humic Acids with Fungal Laccase  [PDF]
Natalia A. Kulikova, Valentina N. Davidchik, Eugenia A. Tsvetkova, Olga V. Koroleva
Advances in Microbiology (AiM) , 2013, DOI: 10.4236/aim.2013.32023

Humic acids (HA) are one of the main environmental factors controlling the fate and behavior of the compounds released into the environment. In particular, they are universally considered of great importance in determining soil extracellular enzyme activity and stability via association with essential soil enzymes. The objective of this study was to investigate the interaction of coal HA with an extracellular multicopper oxidase laccase (EC that catalyze the oxidation of a wide range of reducing substances in the environment. Using size-exclusion chromatography analysis and monitoring laccase activity, the formation of a stable and an enzymatically active complex between HA and laccase was shown. Basing the data obtained by isoelectric focusing of HA-laccase complex, non-covalent character of laccase association with HA was considered and binding of laccase to HA by weak dispersive forces such as van der Waals, hydrophobic, π-π, CH-π and others was hypothesized.

Singular Value Decomposition of Images from Scanned Photographic Plates

Physics , 2013,
Abstract: We want to approximate the mxn image A from scanned astronomical photographic plates (from the Sofia Sky Archive Data Center) by using far fewer entries than in the original matrix. By using rank of a matrix, k we remove the redundant information or noise and use as Wiener filter, when rank k
Os trópicos na rota do Império britanico: a vis?o de Mungo Park sobre a áfrica em fins do século XVIII
Viana, Larissa;
História, Ciências, Saúde-Manguinhos , 2011, DOI: 10.1590/S0104-59702011000100003
Abstract: the young scottish physician mungo park, aged 23, arrived in africa in 1795 with a mission as specific as it was complex in those bygone days, namely to travel the entire length of the river niger. in 1799, the story of this journey was published in a book that sold 1500 copies in the first month alone, with two further editions published that same year, as well as the translation of the work into french and german the following year. in this article, the narrative of mungo park is examined by taking due consideration of the relationship between the tropics, science and travel in the early days of british expansionism into the heart of africa.
