Key Issue - How to share and discuss your research successfully online
No full textWhen I first started working in the field of online dissemination of academic research, about
four years ago, I asked a lot of questions around why it is important to share your work
online. Over the years, my questions have now shifted away from ‘Is this an important thing
to do?’ (Yes, it is), to ‘How can we do this important activity well?’
As I work with researchers at the University of Huddersfield across all disciplines, one of
the first things I learnt was that the success of online dissemination and promotion requires
different tools, methods and approaches depending on the subject area covered and the
aims of the researcher. That said, there are certain central tenets that, if applied in a tailored
way to your online activities, will help you to expand and engage your networks more
successfully. I am going to cover five of these, and apply them broadly across a range of
online platforms that you might be considering using
Epistemic Communities and Two Goals of Delegation: Hormone Growth Promoters in the European Union
No full textVersion reproduced with the permission of the publisher. Copyright © Beech Tree Publishing 2010The delegation literature tells us that decision-makers delegate power to agents to achieve efficiency or
credibility (or both). Critically, however, the successful delivery of each of these implies very different
levels of control over their agent by the principal. This paper deploys principal–agent modelling to
explore how this logic works with epistemic agents. It explores the implications of two epistemic
community’s contrasting de facto independence from European Commission decision-makers for the
delegation goals satisfied in formulating policy on hormone growth promoters. Analysis supported the
view that to deliver policy efficiency an epistemic community must have low autonomy from the
political principal. Policy credibility was achieved when decision-makers selected an epistemic
community whose views were socially legitimate.This paper is based on doctoral research funded by the UK’s Economic and Social Research Council studentship R00429834387.

Tension strength capacity of finger joined beech lamellas
No full textBeech wood has high mechanical properties, therefore the production of high quality beech glulam beams is one of our main objectives. Finger joints with standard geometries and adhesives used for joining coniferous wood are not sufficient in terms of strength when gluing beech wood. A hybrid glulam beam was produced and tested in a standard four point bending test. The beam was produced from finger joined beech lamellas on the outer sides and finger joined spruce lamellas in the middle. The results from the bending test showed a lack of tensile strength of the finger joints of beech lamellas on the bottom middle part of the beam, where the rupture occurred. We prepared a numerical model of finger joined beech lamellas and simulations of tension tests, parallel to the lamella. We performed parametric studies with multiple variables referring to geometrical properties of finger joints and two different types of applied adhesives. The results showed a high influence of the finger joint geometrical parameters. Experimental tests on the tension strength of the finger joints were performed. Two finger joint lengths were tested, 10 and 20 millimetres. The results showed a clear influence of the finger joint geometry where highest strengths were obtained with longer and thinner fingers
French beech – a new opportunity in wood housing
No full textHardwood housing especially from beech is one item of possible added value products based on solid wood and / or wood reconstituted in Europe. However, design of structures requires structural product with a certified strength according to regulatory framework of CE marking. French beech forest occupies about 1.4 Mha lead mainly in regular high forests and coppices with standards with an annual volume of harvested wood (1 million m3) for a sawn timber estimated at 400000 m3. FCBA has launched since in 2011 a study to characterize the French beech as a raw material and its structural bonding. To qualify French beech species as solid wood, a national representative sampling was performed to collect 2400 lumbers (6 French areas, 21 stands, 99 trees, 3 cross-sections) and to establish visual grading rule (NF B 52 001-1 2017) for assessment in D40-D24 or D35-D18. A new table of strength classes of European hardwood (EN 338) will be proposed according to experimental results. Grading machine could be done for D50 with a good yield (38-47%). A general work plan has been developed to reach requirements for beech glulam in two steps. Firstly, the compatibility of different type I adhesives technology was studied by the way of lab tests usually performed in the field of common adhesives approval (EN 302-2). On the other hand, full scale tests according to EN 14080 have been done to characterize glulam beams (58 beams - GL32h) with verification of finger joint performance. French beech data could be merged with other hardwood data to develop a GLT CE marking standard as EN 14080 part 2 specifically devoted to hardwoods. The construction market in the future could provide an important alternative for French beech, particularly in the form of reconstituted products
Tensile strength grading of beech (Fagus sylvatica L.) lamellas from multiple origins, cross sections and qualities
No full textThe market share of European beech (Fagus sylvatica L.) wood in the construction sector is low despite an increase in beech stock in Central European Forests in recent years. More efficient sawing techniques, higher lamella grading yields and solving of adhesion challenges may increase the competitiveness of beech glulam and promote its use. The aim of this paper is to revise the lamella grading system in the current German technical approval for beech glulam Z-9.1-679:2019 (DIBt (2019). BS-Holz aus Buche und BS-Holz Buche Hybridträger und zugehörige Bauarten. Allgemeine bauaufsichtliche Zulassung Z-9.1-679:2019. Deutsches Institut für Bautechnik) and to suggest modifications in the lamella grading rules for glulam production allowing higher yields and reliable tensile strength values at the same time. The unique dataset in this study combined different origins of lamellas and covered a wide range of visual, physical and mechanical wood characteristics including a high amount of low quality material. Indicating properties (IPs) for tensile strength, such as knot parameters and dynamic modulus of elasticity, were contrasted with tensile strength and static modulus of elasticity. Beech lamellas, graded by means of Z-9.1-679:2019 (DIBt (2019). BS-Holz aus Buche und BS-Holz Buche Hybridträger und zugehörige Bauarten. Allgemeine bauaufsichtliche Zulassung Z-9.1-679:2019. Deutsches Institut für Bautechnik), did not achieve the tensile strengths required for glulam production in many grading classes and the yield was low. A machine grading approach with dynamic modulus of elasticity as a single grading criterion gave higher yields than the current grading procedure and high reliability for tensile strength prediction with a prediction accuracy of R2 = 0.67.

Nitrogen mineralization in southern beech forests.
No full textNitrogen mineralization has been studied in the slightly acidic brown earth on limestone of a beech stand and a beech-fir stand, in the forests of Monte Taburno (Campania Apennines). NH4 is the predominant form of the mineral N in the soil of both stands. Yearly NO3- production is 42.4 kg ha-1 in the beech stand and 47.0 kg ha-1 in the beech-fir stand.-from Author
Auswirkungen der Einbringung von Buche (Fagus sylvatica L.) auf die Artendiversität und Naturnähe von Nadelholzbeständen in Niedersachsen
No full textThe promotion and extension of continuous cover mixed stands with a simultaneous reduction of conifer-monocultures play a major role in current silvicultural practices in Central Europe. It is assumed that the admixture of the natural dominant beech (Fagus sylvatica) in pure non site-specific conifer stands automatically indicates better conditions in terms of nature conservation and forest management. To test this hypothesis three different conifer-beech-comparisons of pure and mixed stands in Lower Saxony are studied, analyzing plant species diversity and naturalness of understory vegetation as one important indicator for the ecological status of forests. Each comparison includes pure coniferous stands (Picea abies, Pinus sylvestris, Pseudotsuga menziesii), mixed coniferous-beech-stands, and pure beech stands on similar acidic mineral soils where the potential natural vegetation will be an oligotrophic beech forest (L u z u l o - Fa g e t um). The age of stands varies between 50 and 150 years. To specify tree species influence on site conditions and vegetation, the study also includes light climate and soil data of the stands. It is observed that, with regard to all comparisons, the admixture of beech reduces plant species diversity but increases naturalness of the stands. The intensity of beech admixture effects differs. While in Scots pine stands the impact of admixed beech is very noticeable, with the mixed stands being nearly identical with pure beech stands, the species change in Douglas-fir and Norway spruce stands proceeds more slowly. Assuming that the status in nature conservation and forest management is improving with increasing plant species diversity and increasing naturalness, the results of this study show a contrary development on a stand scale, as the potential natural vegetation of the L u z u l o - F a g e t u m is in its self very species poor on vascular plants.Die Förderung und Ausweitung von Mischwäldern bei gleichzeitiger Reduktion reiner Nadelholz-Bestände spielt aktuell eine große Rolle im mitteleuropäischen Waldbau. Gemeinhin wird angenommen, dass die Beimischung der standortsgemäßen Buche (Fagus sylvatica) in standortsfremden Nadelholz Monokulturen die Bedingungen im Sinne des Naturschutzes und der Forstwirtschaft verbessert. Diese Hypothese wird auf der Grundlage von drei unterschiedlichen Nadelholz- Buchen-Versuchsreihen geprüft. Im Mittelpunkt steht dabei die Bodenvegetation als wichtiger und sensitiver Indikator für den ökologischen Zustand von Wäldern. Jede Versuchsreihe umfasst reine Nadelholz-Bestände (Picea abies, Pinus sylvestris, Pseudotsuga menziesii), Nadelholz-Buchen- Mischbestände und reine Buchen-Bestände auf sauren Mineralböden, auf denen von Natur aus nährstoffarme Buchenwälder (L u z u l o - Fa g e t um) vorherrschen würden. Das Alter der Bestände variiert zwischen 50 und 150 Jahren. Schwerpunkte der Analyse sind die Artenvielfalt und Naturnähe der Bodenvegetation. Um den Einfluss der Baumarten auf den Standort und die Vegetation zu bewerten, werden die Licht- und Bodenverhältnisse der Bestände charakterisiert. Es zeigt sich, dass mit der Beimischung der Buche in allen Versuchsreihen die Pflanzenartenvielfalt abnimmt und die Naturnähe zunimmt. Unterschiedlich ist dabei die Intensität der Veränderungen. Zwischen den Kiefern-Buchen-Mischbeständen und den Kiefern-Reinbeständen bestehen sehr deutliche Unterschiede im Aufbau der Bodenvegetation, so dass die Mischbestände den Buchen-Reinbeständen bereits sehr ähnlich sind. In den Douglasien- und Fichten-Versuchsreihen vollzieht sich der Artenwechsel vergleichsweise unauffällig und kontinuierlich. Wenn man davon ausgeht, dass der naturschutzfachliche und waldbauliche Status sich sowohl mit zunehmender Phytodiversität als auch bei zunehmender Naturnähe verbessert, so zeigen diese Ergebnisse auf Bestandesebene eine gegenläufige Entwicklung, da das in der Region der potenziell natürlichen Vegetation entsprechende L u z u l o - Fa g e tum von Natur aus sehr artenarm an Gefäßpflanzen ist
