Basic substances: a new opportunity for approval copper at EC phytopharmaceutical regulation 1107/2009
Bio control agents:
BCA, promising for plant protection are the combination of macro organisms, microorganisms, chemical mediators (pheromones, semiochemicals), and natural substances (from mineral, animal, or vegetal origin).
EC regulation:
Following, the enter in vigour of the new phytochemical EC Regulation 1107/2009 on May 14th 2011, the opportunity of approval at EU level, for new categories, are now available. Together with regular active substances, as previously managed by Dir 91/414, two new categories were introduced “Basic Substances” described via Article 23 and “Low Risk Substances” defined in Art. 22. Further specific EU-Guidance documents, regarding data requirement, are available or in progress for BCAs sub-category: microorganisms (baculovirus), pheromones (sclp) or botanicals.
a. Opportunity of testing the first category (basic substances) for plant extract and light compounds as agriculture aid was engaged by ITAB in 2011 and ended up with an EU-Guidance document, available as working document (SANCO/10363/2012 rev.7) managed by DGSanco in one hand, and Equisetum (Horsetail) BSA pilot project in the other hand.
b. Implementation of the second category (Low Risk substances) is in progress in order to produce equivalent Guidance document for early 2014.
Basic substances:
As matter of fact, these approvals as basic substance are by derogation to general pesticide regulation. Opportunity of the use of plant water extract (Nettle) and food compounds (sugars) in agriculture was not previously attach to any regulation, except in organic farming although some were approved at EC Directive 91/414 (Garlic extract, acetic acid) but as phytopharmaceuticals. Among these alternative products used for crops protection, notably from plants, natural extracts used traditionally by gardeners or farmers, are deemed potentially interesting. The use of these natural extracts preparations can be done now in compliance with regulatory requirements as plant protection substitution product, or plant defense enhancer for agriculture, and especially organic farming
Basic Substances under EU Pesticide Regulation: An Opportunity for Organic Production?
Some of the active substances allowed in organic production are now approved as basic sub- stances under the EU plant protection products regulation. Previously, all organic farming permitted active substances were approved as conventional plant protection products. In accordance with the criteria of Article 23 of the EU regulation (EC) No 1107/2009, basic substances are granted without maximum residue limits and have a good prospect for being included in Annex II of organic farming Regulation (EC) 889/2008. In fact, most of them are already permitted in organic farming. At this stage, it seems desirable to organize applications in order to avoid duplications and to clarify strategy across Europe. This organization should be planned in order to identify corresponding knowledge and data from field experiments, and to further constitute the most crucial issues related to organic production. A work of this nature was initially supported by IFOAM-EU for lecithin, calcium hydroxide and Quassia extract. The Institut Technique de l’Agriculture Biologique (ITAB) was previously engaged in a large-scale approval plan motivated by the continuous demand for the regularization of compounds/substances already in use and has a mandate for testing and approving new compatible substances. Thus, the horsetail extract (Equisetum arvense) was the first approved basic substance and ITAB has obtained 11 of the 15 basic substances approved at the EU level
Novel Plant Protection Regulation: New Perspectives for Organic Production
So called ’active substances’ (A.S.) which are allowed in Organic Production are regularly criticized for different reasons. Previously, although permitted in Organic Farming some substances were not approved under EU general plant protection products (PPP) regulation; therefore they were removed for their toxicity or exhibited characteristics (persistence, broad spectrum). Recent approbations under different new Articles of the EC regulation 1107/2009, gave rise to substances granted without maximum residue limits (MRL). We previously described approved basic substance (Art. 23) as potential candidates for organic farming; here we describe low risk substances (Art. 22) as new implements for substitution of controversial organic biopesticides and consequently as candidates for substitution (Art. 24)
Proton electron elastic scattering and the proton charge radius
It is suggested that proton elastic scattering on atomic electrons allows a
precise measurement of the proton charge radius. Very small values of
transferred momenta (up to four order of magnitude smaller than the ones
presently available) can be reached with high probability.Comment: 4 pages, 4 figure

Time-trends and treatment gaps in the antithrombotic management of patients with atrial fibrillation after percutaneous coronary intervention: Insights from the CHUM AF-STENT Registry.
BACKGROUND: The management of atrial fibrillation and flutter (AF) patients undergoing percutaneous coronary intervention (PCI) has undergone a rapid recent evolution. In 2016, the Canadian Cardiovascular Society (CCS) published expert recommendations to help guide clinicians in balancing bleeding and thrombotic risks in these patients. HYPOTHESIS: Antithrombotic regimen prescriptions for AF patients undergoing PCI evolved after the publication of the 2016 CCS AF guidelines. METHODS: A prospective cohort of AF patients undergoing PCI with placement of a coronary stent from a single tertiary academic center was analyzed for the recommended antithrombotic regimen at discharge. Prescribing behavior was compared between three time periods (Cohort A [2010-2011]; Cohort B [2014-2015]; Cohort C [2017]) using the χ2 test. In addition, antithrombotic management in Cohorts B and C were compared to guideline-recommended therapy. RESULTS: A total of 459 patients with AF undergoing PCI were identified. Clinical and procedural characteristics were similar between cohorts, with the exception of an increase in drug-eluting stent (DES) use over time (P < .01). Overall, the rate of oral anticoagulation (OAC) increased over time (P < .01), associated with an increase in nonvitamin K OAC prescription (P < .01) and a concomitant decrease in vitamin K antagonist prescription (P < .01). Despite this, the overall rate of anticoagulation remains below what would be predicted with perfect guideline compliance (75% vs 94%, P < .01). CONCLUSION: There has been a dramatic shift in clinical practice for AF patients requiring PCI, with increases in prescription of OAC even in the context of an increase in the use of DES. However, room for further practice optimization still exists
Student entrepreneurship: A research agenda
The purpose of this paper is to define the term “Studentpreneur” and stimulate research in the field of Student Entrepreneurship. A research agenda is proposed to further the knowledge of Student Entrepreneurship. The paper identifies Student Entrepreneurship as an emerging phenomenon that provides a dual opportunity. The first is the opportunity to zoom in on one category of entrepreneurs and observe if the traditional theories developed in the “meta category” of entrepreneurs apply to this subcategory; for example, Traits, Psychological tests and Dynamic Capabilities, in a goal to legitimate them further. The second opportunity is to study Studentpreneurs as an exemplary case. Two themes are suggested for the research agenda linked to the latter opportunity: Identity Construction and management of Multiple Identity

Oceans Act: Uncharted Seas For Offshore Development In Atlantic Canada?
Canada\u27s Oceans Act, now five years old, is a ground-breaking piece of legislation in marine law which provides a framework for the development of a national oceans strategy, integrated planning and management, and institutional responsibilities. In this article, the authors review the Act and its issues and argue that the uncertainties found there provide opportunities for participants in the Atlantic Canada offshore oil and gas industry to influence the development of an oceans policy, legal and institutional framework that accommodates all interests
Un aspect peu connu de la francophonie canadienne de l'Ouest: le français hexagonal
L'un des aspects les moins connus de l'histoire de la francophonie de l'Ouest canadien est sa complexité, due en grande partie au fait qu'elle découle de trois souches distinctes: premièrement les Mitchifs, descendants des premiers coureurs des bois, suivis un siècle plus tard des colons venant soit directement du Bas-Canada soit des états américains où les Canadiens s'étaient déjà établis (les états de la Nouvelle-Angleterre et certains états du Midwest), troisièmement, la présence relativement importante, dans certaines communautés rurales, de colons francophones venus de France, de Belgique et de Suisse. Ces colons sont arrivés dans l'Ouest à partir des années 1880 et ont continué de s'y installer jusqu'aux années 1930. Ces agriculteurs, éleveurs ou simples ouvriers, ont fondé plusieurs communautés où ils étaient fortement majoritaires; ailleurs, ils se sont installés dans des communautés francophones en nombre suffisant pour représenter une influence certaine et durable sur le vernaculaire local. Dans cette étude, nous nous arrêterons brièvement à l'histoire de quelques-uns de ces villages et passerons en revue les études linguistiques peu nombreuses qui se sont intéressées à ce phénomène unique au Canada.One of the little known aspects of the history of "la francophonie" in Western Canada is its inherent complexity, due largely to the fact that it is based on three distinct sources: first, the Mitchifs, descendants of the early "coureurs des bois", followed nearly a century later by colonists coming either directly from Lower Canada or from the American states where the French-Canadians had already settled (the New England states and the Midwest), and third, the relatively important presence, in a number of rural communities, of colonists from France, Belgium and Switzerland. These French-speaking colonists began arriving in the West from the 1880s on and continued doing so until the 1930s. These immigrants were mostly farmers, stockbreeders or blue collar workers and they founded a number of communities where they constituted an important majority or they settled in already established French-speaking villages in sufficient num-bers to exert a noticeable and durable influence on the local vernacular speech. In this study, we briefly review the history of a number of these communities and describe the few linguistic descriptions that have been made of this unique phenomenon in Canada
Flood risk analysis for the river Scheldt estuary
This report gives an overview of the history of flood risk management along the Scheldt estuary. Thepurpose of this overview is twofold. It documents the results obtained in the first activity of the Task25 Pilot, being focused on flood risk analysis, both in historical perspective and with regard to currentpolicies. Secondly, it provides an introduction to the Scheldt estuary for other partners in theFLOODsite project which will use the Scheldt Pilot for their own tasks and activities.The Scheldt estuary is a clear example where integrated water management is required. Integratedmeans in this case: meeting the objectives for 3 major basic functions and values of the estuary: safety,accessibility (navigation) and ecology. Recently finalised and ongoing projects, such as Proses and theSIGMA plan show a highly multidisciplinary approach in order to fulfil these objectives.From the perspective of flood risk management we see a significant difference in approach betweenBelgium and the Netherlands. The Belgian New Sigma Plan has used an approach that is strikinglysimilar to the FLOODsite methodology, i.e. going through the three phases Risk Analysis, RiskAssessment and Flood Management Strategy formulation. In contrast, the Dutch flood riskmanagement was developed over a long historical period, with the Delta Plan as the final apotheosis.In the time the Delta Plan was formulated, there was hardly any attention and technology available todetermine flood probability and flood damage
