Published: December 2020

Termite mounds represent abundant microhabitats of high biodiversity in tropical savanna ecosystems and are an important source of landscape heterogeneity in Sub–Saharan West Africa. Floristic composition as well as density, structure and zonation of plant cover on the mounds were investigated in northern Benin and compared to the adjacent savanna vegetation. A total of 57 abandoned and densely vegetated termite mounds of comparable size and similarly affected by erosion located in different types of savannas inside and outside of the W National Park and in cotton fields were studied. This study revealed that termitaria are special habitats differing in density, composition and structure from surrounding savannas. The plant cover of termite mounds showed a distinctive zonation. Succulents, geophytes, and lianas were much more abundant on mounds, the family Capparaceae was found exclusively on mounds. The floristic composition and vegetation on termitaria proved to be rather homogeneous; although those mounds located in cotton fields differed by higher abundance of Poaceae and lower species richness.

Published: December 2020

AbstractThe understanding of crystal nucleation and growth has evolved over the past two decades from the conventional atom-by-atom model to a non-classical approach, involving particle aggregation and amorphous transformation pathways. Whereas aggregation of particles instead of individual atoms/ions/molecules has been recognized as a common crystallization pathway at the Earth’s surface conditions, few cases are known for high-temperature (e.g., melt) mineralization, which is of great importance for understanding geological processes.Here, we present texture data for natural (e.g., igneous and metamorphic biotite and muscovite) and synthetic (e.g., fluorophlogopite) phyllosilicates suggesting that a particle attachment formation should be considered, although other crystal growth models cannot be excluded. A nonclassical crystallization model is proposed for phyllosilicates forming at elevated temperatures in magmatic and metamorphic environments whereby oriented attachment of building blocks occurs along the (001) plane or the [001] direction, or both simultaneously. In this model, the crystallization of phyllosilicates occurs in steps, with multi-ion complexes forming nanoparticles, and nanoparticles coalescing (self-assembly) to form nano-flakes that become domains in larger crystallites by oriented attachment. Adjacent domains can share a common crystallographic orientation or may be rotated at various angles relative to each other. Nanoparticles may be associated with distorted bonds or may be space separated. Thus, the phyllosilicate grows into a mosaic crystal.Mosaic crystals can also form following classical crystallization models, but the process differs in that the mosaic character involves the intergrowths of nucleation sites (classical crystal-growth process) instead of the coalescence of nanoparticles building blocks (crystallization by particle attachment). These processes may be discerned by the textural differences that result. Oriented particle attachment of building blocks in phyllosilicates is recognized by a loss of closest packing by bond distortion or by space separation at domain boundaries. Crystallization by atom attachment occurs with closest packing within layers, and particles grow independently. The two processes may occur within a single environment and are not mutually exclusive. However, defects generated, for example, by chemical inhomogeneity, mechanical deformation, or sample preparation, cannot be completely excluded, although the use of synthetic, end-member material (e.g., fluorophlogopite) generated from a melt reduces these possibilities. Nonetheless, a particle attachment model is a viable alternative to classical crystal growth processes for high-temperature phyllosilicates with the presented supporting data, although still not yet proven.

Applicability of infectivity assay for the quantification of infectious human adenovirus genotype 5 in UV-irradiated wastewater
Authors: Rattanakul Surapong , Oguma Kumiko 
Published: December 2020

AbstractThe use of infectivity assays in domestic wastewater samples is limited because of the concerns around cytotoxicity to host cells, thus, the UV inactivation efficiency of human adenoviruses (HAdVs) in wastewater remains unclear. In this study, a human adenovirus genotype five (HAdV-5) host cell line (A549 cells) was incubated with wastewater at varied dilutions from 1:1.5 to 1:4 (the ratio of wastewater to a mixture of wastewater and the cell culture medium) and the cytotoxicity was assessed by the cell morphology and viability. No change was observed in either cell viability or morphology in comparison with control samples, even at lowest dilution of 1:1.5, indicating the dilution allowed infectivity assays. The minimal degree of dilution to avoid cytotoxicity may differ with different water matrix. Consequently, the technique was applied to quantify spiked HAdV-5 after the UV disinfection of wastewater. A significant increase in UV disinfection efficiency was noted in wastewater and hydroxyl radicals (OH•) produced by the photosensitization of dissolved organic matter were suggested to be responsible for the enhancement. This study indicated that dilution can be a simple solution to avoid cytotoxicity, and UV inactivation may be enhanced in wastewater due to OH• radicals produced by UV radiation.

Abstract
Deep insight into the forces driving chloramine decay in different pipe materials is the key to taking sound action to cope with pipe water quality deterioration. By using the newly developed RTCDM (refined Total Chloramine Decay Model) and pipe section reactor, the role of four typical pipes in disinfection chemistry was qualitatively and quantitatively compared, and the mechanism of pipe wall mediated chloramine decay was further described. As for the four typical pipes studied, the characteristics of deteriorating water quality, especially for accelerating total chloramine decay was in the order of cast iron pipe &gt; steel pipe &gt; cement lined ductile iron pipe &gt; polypropylene-random pipe. Cast iron pipes, cement-lined ductile iron pipes, and steel pipes of long service age are characterized by one or two driving forces leading to TCR decay. Aged cast iron pipes could take up chloramine by Fe(0) and microbes (especially nitrifiers) spreading over the inner wall. Aged steel pipe is characterized by aggressive electrochemical corrosion and weak nitrification. Lime and gypsum leaching is the main cause, and nitrification/denitrification may also occur in aged cement-lined ductile iron pipe. Polypropylene-random pipes have a minimum effect on disinfection chemistry. This knowledge is of value in speculating the reasons leading to TCR loss in the full scale distribution system.
Burla, controle de si e disfarce da comensalidade
Authors: Previatti Débora , Horn Bianca 
Published: December 2020

A alimentação contemporânea é marcada pela afirmação de preferências alimentares que tensionam e transfiguram as práticas “tradicionais” de refeição compartilhada. Este artigo tem por objetivo investigar os sentidos atribuídos às práticas alimentares e os marcadores sociais em narrativas de indivíduos adeptos de dietas livres de glúten e/ou lactose residentes em Porto Alegre. Foram realizadas treze entrevistas em profundidade, além da observação assistemática de blogs e fanpages de celebridades referenciadas pelos entrevistados. Uma economia psíquica, de caráter disposicional e contextual, vigora nas sociabilidades por meio de intenso autocontrole e de mecanismos de burla. Estes são mobilizados a fim de escapar das convenções sociais, pesando sobre juízos de gosto, nos quais por vezes também operam marcadores de distinção social.

Amplitude error correction in matrix simulators of radar targets
Authors: Sabitov T. I. , Kiselev A. V. 
Published: December 2020

Problem statement. The compensation problem of the amplitude error occurring when modeling radar targets using matrix simulators is considered. The relations that reveal the concept of this error are given. The example shows that the amplitude of the simulated echo signal differs from the amplitude of the real one.Objective. Justification of a method for correcting the amplitude error observed when simulating echo signals from radar targets using emitter matrices.Results. It is shown that when the scanning radiation pattern is oriented normal to the matrix base, the amplitude of the simulated echo signal does not depend on the angular target position. Based on this, a method was proposed to eliminate the error through pre-distortion of the echo signal amplitude. The ratio for calculating the predistortion multiplier coefficient is obtained. In the framework of a numerical experiment, the amplitude of the simulated echo signal was estimated for various angular positions of the scanning radiation pattern without taking into account predistortion and with predistortion. The experimental results confirmed the correction effectiveness.Practical implications. The results obtained allow increasing the adequacy of modeling radar objects by matrix simulators by ensuring that the amplitude of the simulated echo signal corresponds to the amplitude of the real one.

Published: December 2020

In this study, the effect of material temperature during casting on fresh properties, hydration kinetics, and early-age compressive strength of self-consolidating concrete (SCC) was evaluated. Concrete equivalent mortars (CEMs) based on SCC mixture designs with water-to-binder ratios of 0.41 and 0.45 were investigated. The SCC mixtures are targeted for infrastructure and building construction and precast applications. The CEMs were prepared at temperatures ranging from 8 to 36°C. Superplasticizer (SP) and air-entraining agent (AEA) demand were evaluated for the CEM mixtures made with different supplementary cementing material (SCM) and limestone filler types. Test results showed that the ambient temperature can significantly affect the SP and AEA demand, hydration kinetics, and compressive strength after 1 d of age. According to the ultraviolet–visible spectrophotometry (UV/Vis) test, the absorption rate of polycarboxylate-based SP decreased with temperature. In contrast, the sensitivity of polynaphthalene sulfonate-based SP to temperature was minimal. Relationships between the variations of different admixture contents, heat flux, and compressive strength with temperature were developed. For a constant slump flow and air content, the demand of the SP and AEA, heat flux, and 1-d compressive strength of CEMs increased linearly with material temperature.

Возможности использования шкалы Bronchitis Severity Score для оценки эффективности лечения острого бронхита у детей
Authors: Abaturov A.E. , Tokareva N.M. 
Published: December 2020

Актуальность. В течение последних почти ста лет в структуре общей заболеваемости острые респираторные вирусные инфекции (ОРВИ) занимают первое место, что подтверждено информационными бюллетенями Всемирной организации здравоохранения и официальными статистическими и эпидемиологическими правительственными отчетами различных стран по проблемам здоровья ребенка. В мире, независимо от уровня развития страны, уровень заболеваемости ОРВИ у детей превышает уровень всех инфекций в 7–7,5 раза, что в 1,5–3 раза больше, чем у взрослых, а в когорте детей до 3 лет их удельный вес составляет до 65,0 % от всех зарегистрированных острых инфекционных заболеваний. По данным украинских исследователей, у 20,0 % пациентов с ОРВИ регистрируется острый бронхит (ОБ). В возрасте от 1 до 3 лет заболеваемость ГБ достаточно постоянная и колеблется в пределах 75–250 на 1000 детей, а среди госпитализированных в инфекционные отделения для детей с респираторной патологией у каждого второго или третьего ребенка верифицирован диагноз ОБ, что составляет от 50,0 до 75,0 % госпитализированных. В этиологической структуре ОРВИ каждые 15–20 лет происходят изменения состава основных возбудителей, что, несомненно, влияет на существующие дигностические и лечебные мероприятия относительно терапии ОРВИ. В последнее время исследования относительно этиологии инфекций верхних дыхательных путей показали, что чаще всего причинно-значимыми факторами являются вирусы, а использование современных методов диагностики позволяет установить этиологический фактор ОРВИ в 56,0–80,0 % случаев. Цель исследования: ­изучить клинико-иммунологические особенности течения ОБ у детей от 1 до 6 лет с оценкой тяжести состояния в остром периоде заболевания и в периоде реконвалесценции с использованием шкалы Bronchitis Severity Score (ВSS); определить клинико-анамнестические и лабораторные факторы риска развития длительного течения ОБ у детей от 1 до 6 лет. Материалы и методы. В работе приведены материалы клинического наблюдения, клинико-лабораторного и инструментального обследования 122 детей в возрасте от 1 до 6 лет с ОБ. Выводы. Установлено, что клинико-анамнестические предикты (перинатальное поражение центральной нервной системы, низкая масса тела при рождении, курение матери), степень тяжести ОБ (по показателю общего количества баллов по BSS) и фазовые изменения концентрации антимикробных пептидов и интерферонов определяют риск развития длительного течения заболевания. Определение степени тяжести состояния у детей с ОБ с использованием BSS позволяет усовершенствовать терапевтические мероприятия и предоставляет возможность дифференцированного выбора патогенетически обоснованного лечения на этапе стационарного ведения пациентов.
