Assessing non-chemical weeding strategies through mechanistic modelling of blackgrass (Alopecurus myosuroides Huds.) dynamics

2010

 ; Because of environmental and health safety issues, it is necessary to develop strategies that do not rely on herbicides to manage weeds. Introducing temporary grassland into annual crop rotations and mechanical weeding are the two main features that are frequently used in integrated and organic cropping systems for this purpose. To evaluate the contribution of these two factors in interaction with other cropping system components and environmental conditions, the present study updated an existing biophysical model (i.e. AlomySys) that quantifies the effects of cropping system on weed dynamics. Based on previous experiments, new sub-models were built to describe the effects on plant survi…

In-mouth aroma compound release during cheese consumption: Relationship with food bolus formation

2011

International audience; The present study describes the changes in mechanical properties and saliva incorporation for cheese samples with different composition and texture, and their influence on the rate of aroma release. Chewing work per cycle, salivary flow rate and chewing rate varied highly among subjects. Despite the differences in cheese hardness, at the end of mastication, bolus texture was the same for cheeses with the same lipid content. Low-fat cheeses gave harder bolus than high fat ones, despite being chewed longer, with higher work per cycle and more moisture. Salivary flow rate did not vary among cheese samples but, at the end of mastication, the amount of saliva in boluses d…

Effect of growing area on tocopherols, carotenoids and fatty acid composition ofPistacia lentiscusedible oil

2014

International audience; In this investigation, we aim to study, for the first time, the effect of the growing area on tocopherols, carotenoids and fatty acid content of Pistacia lentiscus fixed oil. Fruits were harvested from eight different sites located in the north and the centre of Tunisia. Tocopherols, carotenoids and fatty acid content of the fixed oils were determined. The highest carotenoid content was exhibited by Feija oil (10.57 mg/kg of oil). Oueslatia and Tabarka oils displayed the highest alpha-tocopherol content (96.79 and 92.79 mg/kg of oil, respectively). Three major fatty acids were determined: oleic, palmitic and linoleic acids. Oleic acid was the main fatty acid presenti…

Growth and development of Ambrosia artemisiifolia L. under different trophic conditions

2014

Ambrosia artemisiifolia L. (common ragweed) is an annual weed regarded as an invasive plant in France. This species can be found in a large range of soil types with regard to texture, pH or nutrient contents. Furthermore, its tolerance to different forms of stress increases its spread potential. This work was undertaken to evaluate the development and growth of common ragweed under different trophic conditions in a common garden. Three cohorts of 15 plants per treatments were sown in spring 2013 and the effects of nitrogen and irrigation were compared on each sowing dates. During the first weeks, vegetative appearance is strongly linked with the sum of temperature. For the first cohort, the…

Combustion wave structure during the MoSi2 synthesis by Mechanically-Activated Self-propagating High-temperature Synthesis (MASHS): In situ time-reso…

2006

Abstract In situ synchrotron time-resolved X-ray diffraction experiments coupled with an infrared imaging camera have been used to reveal the combustion wave structure during the production of MoSi2 by Mechanically Activated Self-propagating High-temperature Synthesis (MASHS). The fast combustion front exhibits a form described as an ‘equilibrium structure’ where the chemical reaction is the sole major driving force. In the MASHS process, oxide-free interfaces between Mo and Si nanocrystallites enhance the reaction Mo+2Si→MoSi2. Exhaustive time-resolved investigations show a possible solid-state process in the first second of the reaction within the combustion front. If preheating is added,…

Rethinking Academic Literacies: Designing multifaceted academic literacy experiences for pre-service teachers

2013

This manuscript introduces a multidimensional framework for academic literacies to help instructors become more aware of different aspects of literacies and how they might be used to plan and orchestrate meaningful, multifaceted literacy experiences in their classes. More specifically, this broad framework for literacy and learning explicitly considers the overlapping role of argumentation, digital inquiry, collaboration, and innovation as they are applied to continuously evolving disciplinary literacy practices. The framework is applied to a course designed for pre-service teachers that integrated several aspects of academic literacies and offered some pedagogical guidelines to support the…

Tērvetes pilskalna akmens lejamveidnes

2017

No analizētajām Tērvetes pilskalna 25 lejamveidnēm 2 ir pusfabrikāti. 10 veidnēs liets metāls, 11 bijusas nelietotas, 2 veidnēm lietosana nav nosakāma. 10 veidnes bija t.s. vāciņi - veidnes apģērba apsuvju un piekariņu aizmugures iegūsanai. Septiņas veidnes bijusas apvērsamās - ar ielietnēm akmens plāksnīsu augsā un apaksā. Akmens plāksnītes - lejamveidnes izgatavosanas procesā ir slīpētas un atsevisķos gadījumos pulētas. Veiddobumi pārsvarā izgriezti ar nazi.---The article analyses 25 finished and semi-manufactured stone casting moulds found at the hill-fort of Tērvete, dated to the 11th–13th century. In terms of construction they all are two-part moulds. Ten moulds have been used for cast…

Urban drinking and driving:comparison of electric scooter and bicycle related accidents in facial fracture patients

2022

In recent years, electric scooters (e-scooter) have emerged as an alternative mode of urban transport due to their availability and effortless use. However, e-scooter-related trauma and injuries, especially to the head, have received wide media coverage and raised public concern about their safety. We aim to determine and compare clinically relevant variables, incidence, and severity between bicycle and e-scooter-related facial fractures and potential protective measures for injury prevention. This retrospective study comprised all patients admitted to a tertiary trauma center with bicycle or e-scooter-related facial fractures between January 2019 and October 2020. Patient- and injury-relat…

Tiempos felices: Transformaciones en las tecnologías psicológicas de gobierno de la subjetividad

2020

This paper traces some inflections in the psy disciplines? discourses and technologies for the government of subjectivity during the last decades. It is focused on exploring different mechanisms through which psychological disciplines ?their discourses, techniques and practices? penetrate social life and contribute to establishing subject models consistent with transformations in the political and economic rationalities of late capitalism. Drawing on previous research in the field of gender politics and happiness discourses in the pop psychological culture, I track a line with three moments: i) the production of psychological individuality and identity normalization; ii) the proliferation o…
