'Workshop for Nagoya Protocol and Plant Treaty National Focal Points in Latin America and the Caribbean’
The capacity-building Workshop for National Focal Points in Latin America and the Caribbean on Mutually Supportive Implementation of the Nagoya Protocol and the International Treaty on Plant Genetic Resources for Food and Agriculture, was held 25-28 September 2018 at the International Potato Center (CIP), Lima, Peru. The workshop was attended by over 60 participants, including National Focal Points for the Nagoya Protocol to the Convention on Biological Diversity and the International Treaty on Plant Genetic Resources (CBD) for Food and Agriculture (Plant Treaty), from 16 countries in Latin America and the Caribbean. The workshop was also attended by representatives from the Secretariats of the Plant Treaty and CBD, the International Seed Federation, farmer and indigenous peoples organizations, national and international agricultural research organizations and experts from the region who have been working for decades on access and benefit-sharing policy issues. The objectives of the workshop were to:
1. Strengthen network ties between National Focal Points within each country and across the regions; 2. Analyse challenges and opportunities for implementing the Plant Treaty and the Nagoya Protocol in a mutually supportive manner, and in ways that advance complementary policy goals, such as climate change adaptation, and improving the livelihoods of indigenous peoples and local communities; 3. Equip participants with tools to help address ‘real life’ scenarios where mutually supportive implementation is important, and 4. Identify the kinds of additional support that countries need to implement the Plant Treaty and Nagoya Protocol in mutually supportive ways
Perception of concept and practice of social power in development interventions in Malawi
The study examined research participants’ perception of social power in intervention programmes in Malawi. Two districts and four villages with active participation in the intervention programmes were purposively selected. Focus group participants were purposively identified, while the snow balling procedure was employed to select key informants. A total of 375 participants consisting of 219 men and 156 women (to better explore the viewpoints of men from those of women) were drawn from the two study locations. Data were analysed by content analysis. The results showed that >98% of participants stated that power meant the ‘capacity of a social actor to influence decisions and secure compliance of other social actors. Less than 98% also perceived ‘power’ as the leadership ability of a social actor but few participants with high level of power shared this construct. Further analysis informed that power was perceived as the act of guiding fellow social actors to plan and implement activities serving common interest while another 50% of respondents perceived power as a mere potential ability to influence. Statistics however showed only 3.7% of relatively powerful social actors from agricultural extension workers and 1.3 % of sexual and reproductive health interventionists shared power as potential ability to influence way of thinking and doing. Therefore, stakeholders of development intervention should recognize experienced social actors and traditions as power indicators since these will enhance effective extension policy process aimed at development intervention among rural populace
Generation of Catalytic Films of Zeolite Y and ZSM-5 on FeCrAlloy Metal
This work details the generation of thin films of structured zeolite catalysts (ZSM–5 and Y) onto the surface of a metal substrate (FeCrAlloy) using in-situ hydrothermal synthesis. In addition, the zeolite Y is post-synthetically modified by acidified ammonium ion exchange to generate US-Y. Finally the catalytic activity of the structured ZSM-5 catalyst films (Si/Al = 11, thickness 146 µm) and structured US–Y catalyst film (Si/Al = 8, thickness 23µm) were compared with the pelleted powder form of ZSM–5 and USY catalysts of similar Si/Al ratios. The structured catalyst films have been characterised using a range of techniques, including X-ray diffraction (XRD), Electron microscopy (SEM), Energy Dispersive X–ray analysis (EDX) and Thermogravimetric Analysis (TGA). The transition from oxide-on-alloy wires to hydrothermally synthesised uniformly zeolite coated surfaces was followed using SEM and XRD. In addition, the robustness of the prepared coating was confirmed by subjecting these to thermal cycling (ambient to 550°C). The cracking of n–heptane over the pellets and structured catalysts for both ZSM–5 and Y zeolite showed very similar product selectivities for similar amounts of catalyst with an apparent activation energy of around 60 kJ mol-1. This paper demonstrates that structured catalysts can be manufactured with excellent zeolite adherence and when suitably activated/modified give comparable cracking results to the pelleted powder forms. These structured catalysts will improve temperature distribution in highly exothermic and endothermic catalysed processes
Multiple use of waste catalysts with and without regeneration for waste polymer cracking
Waste plastics contain a substantial number of valuable chemicals. The wastes from post-consumer as well as from industrial production can be recycled to valuable chemical feedstock, which can be used in refineries and/or petrochemical industries. This chemical recycling process is an ideal approach in recycling the waste for a better environment. Polymer cracking using a laboratory fluidised bed reactor concentrated on the used highly contaminated catalyst, E-Cat 2. Even though E-Cat 2 had low activity due to fewer acid sites, the products yielded were similar with amorphous ASA and were far better than thermal cracking. The high levels of heavy metals, namely nickel and vanadium, deposited during their lifetime as an FCC catalyst, did not greatly affect on the catalyst activity. It was also shown that E-Cat 2 could be used with and without regeneration. Although there was more deactivation when there was no regeneration step, the yield of gases (C2–C7) remained fairly constant. For the first time, these results indicate that “waste” FCC catalyst (E-Cat) is a good candidate for future feedstock recycling of polymer waste. The major benefits of using E-Cat are a low market price, the ability to tolerate reuse and regeneration capacity
Solid state and sub-cooled liquid vapour pressures of substituted dicarboxylic acids using Knudsen Effusion Mass Spectrometry (KEMS) and Differential Scanning Calorimetry
Solid state vapour pressures of a selection of atmospherically important substituted dicarboxylic acids have been measured using Knudsen Effusion Mass Spectrometry (KEMS) over a range of 20 K (298–318 K). Enthalpies of fusion and melting points obtained using Differential Scanning Calorimetry (DSC) were used to obtain sub-cooled liquid vapour pressures. They have been compared to estimation methods used on the E-AIM website. These methods are shown to poorly represent – OH groups in combination with COOH groups. Partitioning calculations have been performed to illustrate the impact of the different estimation methods on organic aerosol mass compared to the use of experimental data

Understanding student use of resources in "rich-media" courses
There is a current trend in course development to increase the number of “rich-media” items available to students; these include items like key-concept videos, interactive activities and quizzes, and even captures of the full lectures. It is therefore important to understand which of these resources students use and gain value from so that we can target the best resources for student learning. This paper looks at several courses taught in the School of Chemical Engineering and Analytical Science at The University of Manchester to several year groups; including lecture based courses, distance learning courses, and non-lecture based activities; that contain “rich-media” resources. The use of these items by students is examined; including number of uses, time of use, and local retention. The student opinion on the items and how they felt has affected their learning is also analysed. This allows results to be presented on the most useful types of resource for students providing information for future development
Affective practices, care and bioscience: a study of two laboratories
Scientific knowledge-making is not just a matter of experiments, modelling and fieldwork. It also involves affective, embodied and material practices (Wetherell 2012) which can be understood together as 'matters of care' (Puig de la Bellacasa, 2011). In this paper we explore how affect spans and connects material, subjective and organisational practices, focusing in particular on the patterns of care we encountered in an observational study of two bioscience laboratories. We explore the preferred emotional subjectivities of each lab and their relation to material practice. We go on to consider flows and clots in the circulation of affect and their relation to care through an exploration of belonging and humour in the labs. We show how being a successful scientist or group of researchers involves a careful choreography of affect in relation to materials, colleagues and others to produce scientific results, subjects and workplaces. We end by considering how thinking with care troubles dominant constructions of scientific practice, successful scientific selves and collectives
Events, Neural Systems and Time Series
Different types of events occurring in computer, neural, business, and environmental systems are discussed. Though events in these different domains do differ, there are also important commonalities. We discuss the issues arising from automating complex event handling systems
