Biosensors Based on Micro-algae for Ecological Monitoring of the Aquatic Environment

This chapter is devoted to research possibilities of using micro-algae as sensor elements for biological sensors of aquatic pollutants. The characteristics of the fluorescence of micro-algae pigments caused by laser light, called laser-induced fluorescence (LIF), were used as informative parameters. It is shown that the functioning of biological sensors is determined by the consistency and concentration of micro-algal cells as well as their internal state, which depends on the temperature, illumination, and chemical composition of the water. The results indicate a significant dependence of the LIF intensities of micro-algae from exposure of heavy metal ions, temperature, and illumination. In text is demonstrated specificity of the reaction of various micro-algae, belonging to different phylum. This fact can be used for identify the phylum of micro-algae in situ, and for the creation the biosensors of ecological monitoring aquatic environment

Local taxonomic spectra in plants, animals, fungi and terrestrial protists show common mathematical patterns

Taxonomic spectra, i.e. relations between supraspecific taxa by the number of included species, remain poorly understood in aspect of the mathematical properties. We studied taxonomic spectra of plants (Magnoliophyta, Bryophyta), animals (Coleoptera, Aves), fungi (Agaricomycetes) and terrestrial protists (Myxomycetes), found in the Homilsha Forests National Nature Park (North-East of Ukraine), and concluded that they correspond to the hollow-curve distribution at the level of genera, families and orders. The spectra of most taxa, as shown by the Akaike information criterion, are closely approximated by the log-series distribution model at all taxonomic levels. This type of distribution is typical for the species abundance curves, based on collections made from small areas. At the same time, in the genera–families–orders row the similarity to the lognormal distribution increases. The central values and variability vary considerably between different taxonomic groups and ranks, however, without affecting the type of distribution. The number of orders in all taxa except Bryophyta has reached the saturation and coincides with the curve of the estimated number of orders according to the Chao1 coefficient. For families and especially genera the correspondence with estimated number of species is much lower. Our results do not confirm the assumption that hollow-curve distributions of taxonomic spectra result from the artificial fragmentation of taxa. These distributions neither depend on the insufficient knowledge about the species composition at the locality, nor reflect the size of the studied area. The presence of such distributions in both local and global biota of different groups may be explained by the common features of their evolution, especially by the existence of relict orphan groups. The fact that in Homilsha Forests the kurtosis and skewness of distributions decreases in the genera–families–orders row can therefore be explained by the relatively low percentage of the high-rank orphan taxa in the local biota. This may be a common feature of communities studied at small geographical scale, since orphan taxa often demonstrate a high level of endemism. Comparative studies of local communities from different climate zones may help to understand how universal are the patterns, described herein

Educación para la salud en la prensa. Análisis de los diarios vascos y navarros

El presente artículo tiene como objetivos describir de manera cuantitativa la cobertura informativa de los temas de salud publicados en los diarios vascos El Correo, Noticias de Gipuzkoa, Noticias de Álava y Berria y en el navarro Diario de Navarra durante la década 2001-2010, determinar cuántas de esas piezas sobre salud presentan un enfoque educativo y recoger diferentes puntos de vista cualificados sobre la función de la prensa en la educación para la salud. Para ello se llevó a cabo un análisis de contenido y entrevistas en profundidad a 5 periodistas y 8 médicos. El estudio concluye que es necesario que los diarios trabajen para mejorar la perspectiva educativa en los textos que publican.This article aims to describe quantitatively the media coverage of health issues published in the Basque newspapers El Correo, Noticias de Gipuzkoa, Noticias de Álava and Berria and in the Navarrese Diario de Navarra during the decade 2001-2010, to determine quantitatively which of those health related articles have an educational approach and, at the same time, to gather different qualified points of view on the press’s role in health education. This study was done with a content analysis and in-depth interviews with five journalists and eight health professionals. The study concludes that it is necessary for the newspapers to work in order to improve health education they usually publish

Preparation and study of growth stimulating activity of 1-propyl-4-(3’-amino-1’, 2’, 4’-triazolo-3’-thiopropinyl) piperidin-4-ol

Results on the obtaining and the study of a plant growth stimulator based on 1-propyl-4-(3'-amino-1’,2’,4'-triazolo-3'-thiopropinyl) piperidin-4-ol are presented in the article. 1-propylpiperidin-4-on and 3-mercaptopropinyl-5-amin-1,2,4-triazolo were obtained with the basic parameters of the synthesis for synthesizing of 1-propyl-4-(3'-amino-1', 2', 4'-triazolo-3'-thiopropinyl) piperidin-4-ol. The structures of the obtained organic compounds were proved using IR spectroscopy and1H and13C NMR spectrometry. The obtained 1-propyl-4-(3’-amino-1’2’4’-triazolo-3’-thiopropynyl)-piperidine-4-ol was tested for growth-stimulating activity on spring wheat grains compared with control (water) and has proved to be a domestic growth regulator «Akpinol-alpha» (KN-2). © 2019, Universitatea Babes-Bolyai, Catedra de Filosofie Sistematica.

Структурно-параметрическое асимметрирование регуляторов в системах с разрывными законами управления

The paper considers a method for accuracy improvement of automatic control systems with break-up control laws. The method presupposes asymmetrizing of a structure or parameters of a non-linear regulator proportionally to destabilizing effects. Some variants of such asymmetrizing with usage of so-called ‘quick’ automatic oscillatory motions for compensation of slow errow components are given in the paper.Рассмотрен способ повышения точности систем автоматического управления с разрывными законами управления, суть которого состоит в асимметрировании структуры или параметров нелинейного регулятора пропорционально дестабилизирующим воздействиям. Показаны различные варианты такого асимметрирования с использованием «быстрых» автоколебательных движений для компенсации медленных составляющих ошибок

Global ocean wave fields show consistent regional trends between 1980 and 2014 in a multi-product ensemble

Historical trends in the direction and magnitude of ocean surface wave height, period, or direction are debated due to diverse data, time-periods, or methodologies. Using a consistent community-driven ensemble of global wave products, we quantify and establish regions with robust trends in global multivariate wave fields between 1980 and 2014. We find that about 30–40% of the global ocean experienced robust seasonal trends in mean and extreme wave height, period, and direction. Most of the Southern Hemisphere exhibited strong upward-trending wave heights (1–2 cm per year) and periods during winter and summer. Ocean basins with robust positive trends are far larger than those with negative trends. Historical trends calculated over shorter periods generally agree with satellite records but vary from product to product, with some showing a consistently negative bias. Variability in trends across products and time-periods highlights the importance of considering multiple sources when seeking robust change analyses.publishedVersio
