Essential oil crops for sustainable agriculture - A review

2009

Multifunctionality and diversification of farming systems, integration of agricultural practices both inter se and with the non-agricultural productive systems operating on the territory, biodiversity safeguards, and reduction in off-farm inputs, are key factors for all modern development strategies in agricultural areas. Such issues are valid worldwide, but are especially true in areas in which the cultivation of the more widespread and “classical” crops is constrained by factors of varying degree and importance. In Mediterranean areas, where many environmental and economic factors often reduce rural areas to marginal conditions, the search for new crop opportunities has become one of the …

Study of quantitative and qualitative variations in essential oils of Sicilian oregano biotypes

2015

Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0–54.4%), γ-terpinene (9.8–30.5%), ρ-cymene (5.2–18.7%), α-terpine…

Characterization and hypericins content in some Hypericum species from Sicily

2014

Different species belonging to the genus Hypericum are distributed into many environments of Sicily, where they represent an important component of wild Sicilian flora (Giardina et al., 2007). Among these, H. perforatum (St John’s Wort) is certainly the most common and famous; its floral parts are largely and traditionally used as a folk herbal remedy for treatment of wounds and burns, and considered an important raw matter for pharmaceutical industry due to their acknowledged antidepressant and sedative properties. Although it is not completely clear yet which compounds are responsible for the biological activity of Hypericum, the European Pharmacopoeia takes as a reference index for evalu…

Wildflowers: opportunities for urban landscapes

2022

The concept of “sustainability” is also becoming of great interest in the management of ornamental and territorial greenery. The new trends in the design of green spaces are aimed both at enhancing their “natural” aspects and at researching schemes characterized by lower maintenance costs. Spontaneous vegetation represents a characteristic component of the urban environment and is always adequate to the conditions of the site in which it is located. In this context, the role of spontaneous herbaceous plants becomes fundamental and constitutes an effective response to the current demand for the defence, conservation and enhancement of biodiversity. So far, the use of spontaneous vegetation f…

The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …

2021

The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…

Variability and trajectories in workplace mood over time: an intra-individual perspective

2021

La presente tesis doctoral ofrece una perspectiva dinámica e intraindividual del constructo de bienestar afectivo en el ámbito laboral. El bienestar afectivo laboral se define como la experiencia frecuente de reacciones afectivas agradables (como la felicidad o la alegría) y la ausencia de reacciones afectivas desagradables (como la ira o la ansiedad) en el trabajo. Experimentar un alto nivel de bienestar afectivo laboral está relacionado con una serie de implicaciones positivas para los individuos. Por ejemplo, los individuos con un mayor nivel de bienestar afectivo laboral tienen una mejor salud mental y física (Wilson et al., 2004), y experimentan una felicidad aumentada en otros ámbitos…

Numerical analysis of the mechanical response of wood glulam beams reinforced through the thickness by FRP rods

2009

The modern use of through-thickness reinforcement in wood glulam (glued laminated) beams, bridging the potential delamination crack faces, has shown to be an effective technological solution to improve their interlaminar fracture strength. In this paper, the behaviour of wood glulam beams is investigated from an experimental and numerical point of view, comparing the mechanical response of unreinforced and reinforced (by FRP rods) beams subjected to four points bending tests. For the numerical analysis, a simple two-phases (joint and reinforcement) interface model has been formulated and implemented in a finite element code. In particular, the classical interface model for adhesive joint, a…

Teachers’ professional agency in a centralisation-decentralisation system and a hierarchical cultural context : the case of Hong Kong

2022

Teachers are frontline actors in actualising educational innovations. In some contexts, teachers’ professional agency is undervalued. This study investigated teachers’ agency and its related workplace affordances in Hong Kong, which features a centralised-decentralisation education governance system, and a hierarchical work culture. The study was based on 21 semi-structured interviews with teachers, and employed a deductive thematic analysis. Agency enactment was categorised into 1) pedagogical agency within classrooms, and 2) relational agency in the professional community. The factors contributing to workplace affordances were grouped as pertaining to 1) the collegial community, 2) school…
