Characterization of the "viable but nonculturable" (VBNC) state in the wine spoilage yeast Brettanomyces.
2012
Although the viable but not culturable (VBNC) state has been studied in detail in bacteria, it has been suggested that maintenance of viability with loss of culturability also exists in eukaryotic cells, such as in the wine spoilage yeast Brettanomyces. To provide conclusive evidence for the existence of a VBNC state in this yeast, we investigated its capacity to become viable and nonculturable after sulfite stress, and its ability to recover culturability after stressor removal. Sulfite addition induced loss of culturability but maintenance of viability. Increasing the medium pH to decrease the concentration of toxic SO(2) allowed yeast cells to become culturable again, thus demonstrating …
Electrical conductivity of glass fiber-reinforced plastic with nanomodified matrix for damage diagnostic
2021
The electrical conductivity of glass fiber-reinforced plastic (GFRP) with epoxy matrix modified by multiwall carbon nanotubes (MWCNT) was studied. The electrical conductivity of nanomodified lamina and multi-layered GFRP was investigated on several levels using a structural approach. Components of the electrical conductivity tensor for unidirectional-reinforced monolayer were calculated similarly as in micromechanics using the conductivity of the nanomodified matrix. The electrical conductivity of multilayer composite was calculated using laminate theory and compared with values measured experimentally for various fiber orientation angles. Calculated and experimental data were in good agree…
Micro-determination of dithiocarbamates in pesticide formulations using voltammetry
2013
Abstract The purpose of this work was to develop a reliable method for the micro-determination of dithiocarbamates (mancozeb, maneb, propineb, nabam, Na(CH3)2DTC, zineb, ziram, ferbam and thiram) in pesticide formulations for agriculture using adsorptive stripping voltammetry (AdSV). The accuracy of analytical method was valued by analyzing simulate formulation samples prepared by us with known amounts of active ingredients. In addition, the applicability of the AdSV procedure for the analysis of DTCs and EBDTCs in micro-samples was evaluated by estimating its recoveries from spiked commercial formulate samples. The accuracy, valuated as recovery percentage ranged between 85% and 97%. The p…
El Voto Económico en España
2015
En general se admite que el estado de la economía influye en los votantes y los políticos son plenamente conscientes de ello. Como dice Kiewiet se apoya al candidato que proporciona 'buenos tiempos', y se va en contra de quien gobierna en época de empeoramiento económico. Antes de otorgar el voto, los electores valoran el entorno político, social y económico del país. Qué les induce a inclinarse hacia un candidato se puede explicar a posteriori, estudiando aquello que determinó el sentido del voto en el pasado. El investigador puede observar un momento del tiempo (una o como mucho dos elecciones), o puede realizar un análisis longitudinal, con el deseo de aclarar qué influye en el votante c…
Dynamics in Interaction in Bilingual Team Teaching: Examples from a Finnish Preschool Classroom
2018
The current study aims to explore team teaching as it is manifested in bilingual interactional patterns in a preschool classroom in Finland. The data was collected in a preschool classroom where a bilingual pedagogy in Finnish (majority language) and Swedish (minority language) was implemented with monolingual Finnishspeaking children. Video recordings were made while two teachers with different predefined language roles were team teaching a class of 20 children during two circle times. A two-level analytic model was developed: on the macro level activity types, participant roles (type of leadership) and language allocation (the teachers’ relative use of Finnish and Swedish) were identified…
Communicating across the borders: managing work-life boundaries through communication in various domains
2021
Communicating work issues at home and home issues at work, also known as across-the-border (ATB) communication, is a part of everyday work and family interaction. This study focuses on the concept of ATB communication, using Work/Family Border Theory, according to which the boundaries between work and private life are seen as negotiated and shaped through social interactions and practices. We argue that through ATB communication, and especially by focusing on what is shared and how, employees can manage boundaries and achieve work-life balance. Altogether, 32 informants, comprising journalists (N = 16) and their relational others (N = 16), were interviewed to investigate the role of ATB com…
Complex plant quality—microbiota–population interactions modulate the response of a specialist herbivore to the defence of its host plant
2022
Many specialist herbivores have evolved strategies to cope with plant defences, with gut microbiota potentially participating to such adaptations. In this study, we assessed whether the history of plant use (population origin) and microbiota may interact with plant defence adaptation. We tested whether microbiota enhance the performance of Melitaea cinxia larvae on their host plant, Plantago lanceolata and increase their ability to cope the defensive compounds, iridoid glycosides (IGs). The gut microbiota were significantly affected by both larval population origin and host plant IG level. Contrary to our prediction, impoverishing the microbiota with antibiotic treatment did not reduce larv…

Doslidžennâ bìologìčnoï aktivnostìvtorinnogo ekstraktu zì šrotu travimaterinki zvičajnoï (Origanum vulgare)
2015
Studied the antimicrobial activity of secondary extract from oregano herbs waste (Origanum vulgare)against 7 standard test strains of microrganisms. Minimum bactericidal concentration of the extract to Staphylococcus aureus ATCC 6538 P-is 3.125-6.25 mg/ml and 6.25-12.5 mg/ml to gram-negative bacteria and Candida albicans ATCC 10231.Total antioxidant activity determined by DPPH, secondary extract at a concentration of 400 ug/ml was 92 %. The tested extract had photoprotective activity. Obtained results confirm the perspective of using waste of oregano herbs for making extracts and creation on their basis of pharmaceuticals, veterinary drugs and cosmetics.
Particle balance and return loops for microplastics in a tertiary-level wastewater treatment plant.
2021
Highlights: Dewatering by centrifugation was a step that removed a high number of MPs from the sludge. Sludge retained especially the fibrous microplactics. Reject water transported microplastics inside a wastewater treatment plant. Disc filter-based tertiary treatment ensured removal of 99% of microplastics in wastewater. Microplastics (MPs) from households, stormwater, and various industries are transported to wastewater treatment plants (WWTPs), where a high proportion of them are captured before discharging their residuals to watersheds. Although recent studies have indicated that the removed MPs are mainly retained in wastewater sludge, sludge treatment processes have gained less atten…
