Multifunctional role of medicinal and aromatic plants: Perspectives and constraints

2008

Multifunctionality is one of the newest claims addressed to agricultural practices, that are nowadays requested to overpass their classical role to furnish food and fibers for human needs, also addressing to the fulfillment of other human necessities, such as to accomplish recreational services and to give a contribute for environmental safeguard. Medicinal and aromatic plants (MAPs) may be an important tool for the advancement of agricultural practice towards multifunctionality: they represent a mean for crop (and economical) diversification, contribute to land valorization by means of their aesthetical value, may fit into integrated agro-industrial pathways, may give raw matters and inter…

Analytical model for the long- distance tracer-transport in plants

2011

International audience; Recent investigations of long-distance transport in plants using non-invasive tracer techniques such as C radiolabeling monitored by positron emission tomography (PET) combined with magnetic resonance imaging (MRI) revealed the need of dedicated methods to allow a quantitative data analysis and comparison of such experiments. A mechanistic compartmental tracer transport model is presented, defined by a linear system of partial differential equations (PDEs). This model simplifies the complexity of axial transport and lateral exchanges in the transport pathways of plants (e.g. the phloem) by simulating transport and reversible exchange within three compartments using j…

THE EFFECTS OF GROWTH REGULATORS ON IN VITRO AXILLARY SHOOT PROLIFERATION AND ROOTING OF ERICA MULTIFLORA

2012

Multiple shoots were induced on nodal segments of a mature plant of Erica multiflora L. Axillary shoots produced on uncontaminated explants were excised, segmented, and recultured on the same medium. The effect of Anderson medium, augmented with different concentrations of 2iP either singly or in combination with NAA, as potential medium for shoot multiplication by nodal segments was investigated. In the following experiment equal molar concentrations of four cytokinins (2iP, kinetin, zeatin, and BA) were studied for ability to induce axillary shoot development from single node stem segments. The highest rate of axillary shoot proliferation was induced on Anderson medium supplemented with 1…

Understanding Consumers’ Convenience Orientation. An Exploratory Study of Fresh-Cut Fruit in Italy

2021

In Western society, the fresh-cut fruit market is experiencing significant growth, especially in Italy, where, in 2019, the fresh-cut fruit sales volume increased by 35% compared with the previous year. This study aims to understand Italian consumers&rsquo

Biogeographic patterns of base-rich fen vegetation across Europe

2014

International audience; Questions: What is the distribution of base-rich fen vegetation and the specia- list species along European biogeographic regions? How do the gradients in spe- cies composition correlate to geography and climate at continental scale? What are the implications of such patterns for the classification of these habitats?Location: Fifteen countries of Central, Western and Northern Europe.Methods: We compiled a vegetation plot database of base-rich fens and related communities including vascular plants and bryophytes. The initial data set with 6943 plots was filtered according to the presence of specialists using discriminant analysis. We used DCA to analyse the correlatio…

The Use of Mobile Payment Systems in Post-COVID-19 Economic Recovery : Primary Research on an Emerging Market for Experience Goods

2021

This study investigated whether mobile payment services could drive post-COVID-19 pandemic recovery in the ‘experience goods’ sector (e.g., tourism) utilising Bandura’s self-efficacy or social cognitive theory. It explored the factors influencing the intention to continue using mobile payment services and the intention to recommend these to others. An empirical survey was conducted to assess the study variables, and the data obtained therefrom were analysed using the industry-standard Cross-Industry Standard Process for Data Mining method. The study results suggest that personal innovativeness and perceived trust influence consumers’ intention to continue using mobil…

Modeling the Sustainable Educational Process for Pupils from Vulnerable Groups in Critical Situations: COVID-19 Context in Lithuania, Latvia, and Est…

2022

The critical situation in education caused by COVID-19 has significantly reduced the involvement of pupils from vulnerable groups, particularly those with low learning achievements. The aim of this study is to reveal the modeling of the sustainable educational process and the factors that ensure optimal learning achievements of pupils from vulnerable groups in general education schools in critical educational transformation situations. To reveal the factors ensuring the sustainability of educational processes, this study was conducted in three Baltic countries (Lithuania, Latvia, and Estonia) involving 1432 subject teachers from public education schools. The results of the study highlight t…

Sustainability Development in Mathematics Education : A Case Study of What Kind of Meanings Do Prospective Class Teachers Find for the Mathematical S…

2019

In this article, our focus is on sustainable development in mathematics education from the point of view of teacher training. The aim was to develop prospective teachers’ content knowledge and pedagogical content knowledge of school mathematics. As a case study, we chose the mathematical symbol “a/b”, and examined how prospective class teachers in Finland connect it to the concepts of fraction, ratio, division, rational number or probability. Mathematics textbooks often have a central role in lessons, and they affect strongly how pupils understand concepts and the relationships between them. We chose languaging as a multi-semiotic approach to interpreting what kind of meanings the prospecti…
