description: The therapeutic applications of curcumin, a phenolic compound extracted from Curcuma species, is limited due to poor bioavailability. To enhance the bioavailability, self-microemulsifying drug delivery systems (SMEDDS) with curcumin were prepared. Ethyl oleate, Tween 80, and Transcutol® P with surfactant: co-surfactant ratio of 2:1 w/w was selected based on the solubility and pseudo-ternary phase diagrams. The optimized formulation (S-Eo3) was evaluated for use of spice oleoresins as curcumin bioenhancers. The oleophilic phase of curcumin containing SMEDDS formulations was then successfully modified by using bioactive oleoresins extracted from two Curcuma species, viz. C. longa (S-CL1) and C. aromatica (S-CA1). The curcumin content in S-Eo3, S-CL1, and S-CA1 were 69.6 ± 0.23, 82.4 ± 0.62, and 88.8 ± 0.46 mg/g, respectively. Thus, by the partial modification of oleophilic phase of SMEDDS with spice oleoresin (acting as bioenhancer) resulted in ∼88 k improvement of curcumin aqueous solubility. The pharmacokinetic study in male Wistar rats showed that the relative bioavailability of curcumin in S-CL1 and S-CA1 were 26- and 29-fold vis-à-vis 22-fold in S-Eo3 compared to curcumin suspension. All the SMEDDS formulations were stable for three months as established by ICH guidelines.

description: Trees and bushes as forage alternatives have a positive effect on cattle feeding, thus reducing the cost of milk and meat production. In the Dominican Republic, farmers use tree branches and fruits to feed their animals. However, they do not know the appropriate management, production potential, leaf: stem ratio and nutritive value of these materials. The objective of this research was to measure the effect of height, cutting frequency, leaf: stem ratio and the production of three forage tree species in a dry sub-tropical forest. The research was conducted at Las Tablas experimental station, Bani, during 2005 and 2006. The usual annual rainfall is 650 mm distributed during the periods May-June and October-November. The ο average annual temperature is 30 C; the soil is sandy loam with pH 7.5. There was supplemental irrigation after each evaluation on a year-old plantation. Plants were 0.5 meters apart with 1.0 meter between lines. The experimental design was a random design with factorial arrangement and three replications per treatment. The factors studied were two cutting heights (0.50 and 0.75 meter) and two cutting frequencies (60 and 75 days). There was an analysis of variance applied at the 5% level. Leaves were separated from the stems in order to obtain their relationship, the production yield on a dry matter basis (kg/ha), nutrient analysis and other parameters. The results showed that there were statistical differences between Albizia and Guazuma. Under these conditions, Gliricidia is a good alternative.

description: We study the propagation of a non-interacting atom laser distorted by the strong lensing effect of the Bose-Einstein Condensate (BEC) from which it is outcoupled. We observe a transverse structure containing caustics that vary with the density within the residing BEC. Using WKB approximation, Fresnel-Kirchhoff integral formalism and ABCD matrices, we are able to describe analytically the atom laser propagation. This allows us to characterize the quality of the non-ideal atom laser beam by a generalized M$^2$ factor defined in analogy to photon lasers. Finally we measure this quality factor for different lensing effects.

description: Banana production is a key economic resource in the French West Indies. It is essential that growers in this region enhance their sales by proposing new products—such as mountain bananas—in response to high market competition from other exporting regions where production costs are lower. The quality of mountain bananas is officially recognised in Europe on the basis of a real taste difference. All French West Indian bananas grown at altitudes over 250 m ASL according to specifications can be sold under the mountain banana label. Mountain banana features can be assessed via objective data. At harvest stage, mountain bananas are denser, bulkier and less susceptible to wound anthracnose, caused by Colletotrichum musae, than lowland bananas, probably because of their higher mechanical resistance. Sensorial differences have also been documented in ripe bananas. At the same harvest stage and under identical ripening conditions, mountain bananas have a firmer texture, more intense yellowish pulp, and higher sugar and aromatic compound contents. A jury taste test analysis confirmed the sensorial differences between lowland and mountain bananas. The results of a multisite study indicated that temperature and rainfall during bunch growth are the main factors that distinguish mountain bananas.

description: Twinning in coarse-grained Zr is ubiquitous but not in nanostructured Zr due to the strong nano-confinement. Here we show that hexagonal close-packed (hcp) twins can proliferate in a nanolayered Zr-Nb as a result of the introduction of ductile body centered cubic (bcc) nanolayers. Both common {11¯02} twins and less common {1¯1¯21} twins are found to propagate across the nanolayers by a novel twin hopping mechanism from one hcp layer to another. The fine ductile bcc nanolayers act as buffers that lower the back stress at the hcp/bcc interface far below that which usually constrains twinning. We report a twin hopping mechanism by which hcp twins are facilitated by the introduction of ductile bcc nanolayers that lessen the back stress and enable the twin to bypass.

Waste not, warm not: poverty, hunger and climate change in a circular food system

Food Security and Poverty

description: Reduction of food loss and waste has received increased attention in recent years. Several spikes in food prices since 2008 have highlighted the hardship that poor people, and especially poor children, face when food is priced out of their reach. With as many as 800 million people still undernourished, of whom about 160 million are stunted young children, the fact that as much as 30% of food is lost or wasted appears unconscionable. Surely the loss could be recovered and channelled towards the hungry! Much of the discussion of food loss and waste has been predicated on this assumption, with the related conclusion that better management and distribution of existing supplies could substitute for investment in increased productive capacity. The assumption is in part borne out by empirical evidence but, as is often the case, the full picture is more complex. Moreover, discussion of food loss and waste in terms of feeding the hungry misses the environmental benefits associated with better management of existing production. Food systems that lose and waste less will generate fewer greenhouse gases and contribute less to global warming. The economics of reduced loss and waste creates both winners and losers, but the environmental calculus has only winners. The policy and institutional arrangements of food systems that generate less loss and waste would look quite different from our present systems.
Number of closed strings emitted from a decaying D-brane

description: We have calculated in the covariant gauge the total number of massless closed strings emitted from a decaying Dp-brane using fermionization technology on the time component of the boundary state. This verifies the computation carried out in the less well known temporal gauge despite differences in renormalization schemes. In addition we have attempted to use the fermionic technique to calculate the total number of closed strings emitted. Our result is difficult to interpret due to the ambiguity involved with rotating it back to Minkowski space.

Subjects: Farm Management

description: Losses at the farm level are among the least understood aspects of food loss and waste throughout the value chain. Estimates differ greatly. Depending on the crop, geographic region and infrastructure available, drivers behind on-farm losses differ greatly as well, as do the solutions necessary to address these losses. This complexity makes it difficult to identify just where to apply interventions to reduce food loss at the farm level. This presentation seeks to examine what is known about on-farm losses, identify major gaps in knowledge, and propose steps forward to help demystify the nature of food loss at the production level. A special emphasis is placed on quantification and measurement of food loss, since the lack of data available around this issue is a major barrier to understanding the best approaches for reducing food loss. The focus then shifts to solutions to food loss, which will be further highlighted through case studies being offered by the next speakers in this session.
MIGNEX Background Paper D2.3: Measuring migration aspirations and related concepts

description: People’s thoughts and feelings about the prospect of migrating are essential for understanding migration dynamics. Surveys can yield rich data, but formulating the right questions requires tackling theoretical and methodological challenges.

Key Takeaways

A review of questions from more than fifty surveys resulted in a new conceptual model of five elements that distinguish questions on migration aspirations from each other.

Field-based testing confirmed the advantage of binary questions and highlighted the importance of treating ‘don’t know’ responses in a sound way.

Surveys should include several complementary questions that cover different aspects of thoughts and feelings about migrating or staying.
Increasing on-farm storage: innovation, prizes and public mechanisms that benefit small farmers

description: Post-harvest losses of grain in the developing world lead to lower incomes among smallholder farmers and reduced farm-level food security. This problem is particularly acute in sub-Saharan Africa where post-harvest losses are estimated at US$1.6 billion per year. Moreover, insufficient on-farm storage solutions often lead farmers to sell soon after harvest and receive lower prices when the market is flooded or, even worse, to buy back grain later in the season at a higher price. Private-sector solutions to post-harvest losses exist, but companies often see low-income farmers as a risky and unattractive market. Smallholders do not understand the benefits, nor feel they can afford the solutions. AgResults’ Kenya On-Farm Storage Project uses prize competitions to incentivise the private sector to bridge this gap and enter into the market. This project is one of six innovative prize competitions of the AgResults Initiative, a partnership between the governments of Australia, Canada, the United Kingdom and the United States, and the Bill & Melinda Gates Foundation. Prize competitions offer an innovative method for the public sector to use funds effectively and efficiently to engage the private sector. In the case of Kenya, the prize encourages companies to design, develop, market and sell new (or redesigned) on-farm storage devices to smallholder farmers. This presentation describes AgResults’ prize competitions, the Kenya On-Farm Storage Project, its impact and its sustainability. It discusses how prize competitions offer the development community an efficient and affordable mechanism to finance development programs in the future.
Mode-coupling theory of the stress-tensor autocorrelation function of a dense binary fluid mixture

description: We present a generalized mode-coupling theory for a dense binary fluid mixture. The theory is used to calculate molecular-scale renormalizations to the stress-tensor autocorrelation function (STAF) and to the long-wavelength zero-frequency shear viscosity. As in the case of a dense simple fluid, we find that the STAF appears to decay as $t^{-3/2}$ over an intermediate range of time. The coefficient of this long-time tail is more than two orders of magnitude larger than that obtained from conventional mode-coupling theory. Our study focuses on the effect of compositional disorder on the decay of the STAF in a dense mixture.

description: Agriculture employs over 70% of the workforce in Laos, one of the least developed countries in the world, and provides approximately 27% of total GDP. Intensifying vegetable production will increase plant pest and disease pressure and significant on-farm losses for the majority of subsistence and smallholder cooperative farmers. Intensification is likely to happen if Laos is to meet the World Trade Organization Agreement on Sanitary and Phytosanitary Measures (the ‘SPS Agreement’) requirements for exports to the ASEAN economic community and international markets. This will be a major challenge in the horticultural production areas of Savannakhet and the Bolaven Plateau because there is little capacity in crop health there to support farmers. In collaboration with Provincial Government authorities and the Australian Government volunteer program (AVID) managed by Scope Global, the Crawford Fund has committed to a long-term program to build capacity in crop health, biosecurity and food safety in Laos since 2009. Engaging volunteer early-career scientists to deliver insect and disease diagnostics training has increased the capacity of local counterparts to provide crop protection advice. Placements provide context-specific training and longer-term sustainability through gradual training, while also giving volunteers an opportunity to engage in a career in international agricultural development. Crawford e-mentors support volunteers in five countries with advice and pro-bono laboratory services – a unique feature of the program. Crop management strategies have already been implemented on key farms with the help of local staff, leading to reduced crop loss and increased yields. This long-term commitment will contribute to rural economic development of the smallholder farm sector in Laos, and facilitate trade in rural commodities.

description: Magnetic skyrmions in 2D chiral magnets are in general stabilized by a combination of Dzyaloshinskii-Moriya interaction and external magnetic field. Here, we show that skyrmions can also be stabilized in twisted moiré superlattices in the absence of an external magnetic field. Our setup consists of a 2D ferromagnetic layer twisted on top of an antiferromagnetic substrate. The coupling between the ferromagnetic layer and the substrate generates an effective alternating exchange field. We find a large region of skyrmion crystal phase when the length scales of the moiré periodicity and skyrmions are compatible. Unlike chiral magnets under magnetic field, skyrmions in moiré superlattices show enhanced stability for the easy-axis (Ising) anisotropy which can be essential to realize skyrmions since most van der Waals magnets possess easy-axis anisotropy.

description: A new model for inflation using modified gravity in the Palatini formalism is constructed. Here non-minimal coupling of scalar field h with the curvature R as a general function f(R,h) is considered. Explicit inflation models for some choices of f(R,h) are developed. By writing an equivalent scalar-tensor action for this model and going over to Einstein frame, slow roll parameters are constructed. There exists a large parameter space which satisfies values of n_s and limits on r compatible with Planck 2018 data. Further, we calculate reheating temperature and the number of e-folds at the end of reheating for different values of equation of state parameter for all the constructed models.

description: Strengthening plant health systems by building capacity to manage existing and emerging pests requires innovative approaches in agricultural advisory services. ‘Plantwise’, a global program led by CABI, delivers improved agricultural advice through networks of plant clinics supported by a knowledge bank (an open access gateway to online and offline plant health information). Plantwise is increasingly deploying ICT tools to ensure correct pest diagnoses and appropriate recommendations to farmers. Together with partners, CABI is deploying SIM-equipped Android tablets to enable real-time capture of pest data and instant access to information that supports diagnosis and pest management advice. These tools enable ‘plant doctors’ to use the Factsheet Library app to access 10,000 factsheets on 4000 plants and 2500 pests. The tablets also allow ‘plant doctors’ to communicate via instant messaging services. At plant clinics, relevant data are logged online to enable CABI and partners to monitor the quality of recommendations, ensure that they are accurate and comply with best practice. Plant clinic data is instantly uploaded onto the Plantwise Online Management System where plant protection agencies can use it to track pest occurrences. Critical components of Plantwise include the use of ICT in training the ‘plant doctors’, the back-up from CABI’s knowledge bases, the use of the evidence of impact of the interventions on crop losses as an indicator of potential to improve food security and farmer livelihoods, and the application of lessons learnt to improve the interventions. All of these are highly relevant to CABI’s overall objectives that contribute to the UN’s Sustainable Development Goals 2 and 17. This paper presents Plantwise as an innovation to reduce pre-harvest crop losses.
Innovating to save on wastages in agri-value chains: global and Indian experience

Subjects: Agricultural and Food Policy

description: Globally, about one-third of food produced for human consumption every year (approximately 1.3 billion tonnes) is either lost or wasted while moving from farm to fork. In developing countries, like India, losses occur more from poor supply chains because of poor infrastructure, while in developed countries it is wasted at the retail and consumer end because of higher standards or sheer neglect. Apart from leading to less food available for all, food loss and wastage entail loss of precious scarce resources – water, land, energy, labour, capital – and adversely affect the environment with greater greenhouse gas emissions, leading to global warming and climate change. Both sets of countries need to do a lot to transform this situation, and save precious natural resources. It is much more cost-effective and sustainable to save the food already produced rather than to keep producing more and more to rot. This can be done by building strong, efficient, compressed and reliable value chains in developing countries through investment in infrastructure, institutional changes and innovation in technology, products, practices and policies. Particularly, the role of packaging at the farm level before moving the produce to processing units/wholesalers/ retailers needs to be recognised in a country like India where packaging is minimal and the absence thereof causes qualitative and quantitative food losses. The situation in industrialised countries requires better production management, de-emphasising appearance standards, more explanatory date marking systems, and raising awareness among consumers about better buying, cooking and recycling methods. This can save food wastages at the retail and consumer levels.
Plastic scintillators for the T2K fine-grained detector
Creators: name: Bryant, Martyn

description: The T2K Neutrino Oscillation experiment consists of a νμ beam produced at JPARC and two detectors: one placed280m downstream, the near detector, and Super-K, which sits 295km downstream. The goal of the experiment is measure the θ₁₃ mixing angle and the phase δ found in the MNSP neutrino mixing matrix by measuring the disappearance of νμ from the original neutrino beam and appearance of νe in the beam as it reaches Super-K. The near detector contains a FGD (Fine Grained Detector) which is designed to provide target mass for the ν μ and then track the particles which come out once the νμ has reacted. The FGD consist mainly of nominally sized 1 cm x 1 cm x 200 cm plastic scintillator bars, which are read out by wavelength-shifting optical fibers (which are in turn read out by MPPC photosensors) threaded through each bar. The bars are glued into a series of XY layers. In November 2006 we successfully extruded 11900 Scintillator Bars at CELCO Plastics in Surrey, BC. On site QA found only 2.5 % of the bars to fall outside of bar specifications. During the November bar production run we scanned 4-10 of each 100 bars within a day of them coming off the production line. We found a variation in the light yields of the bars to be 5%. We set up an aging test for the bars. Three separate measurements were consistent with a 2% per year aging rate. In December 2006 we put our new bars in the M11 beam line at TRIUMF. The light yield of the bars was measured using MIPS. With the beam hitting the far end of the bar and no reflector on the end of the bar the light yield and was found to be adequate for the FGD. I predicted, using a simulation, the difference in light collected by 2 sizes of MPPC, one 1 mm sq and one 1.3 mm sq with a gap of 0.4 mm between fiber and photosensor to be 25%. This was in good agreement with Kyoto groups direct measurement.

description: The therapeutic applications of curcumin, a phenolic compound extracted from Curcuma species, is limited due to poor bioavailability. To enhance the bioavailability, self-microemulsifying drug delivery systems (SMEDDS) with curcumin were prepared. Ethyl oleate, Tween 80, and Transcutol® P with surfactant: co-surfactant ratio of 2:1 w/w was selected based on the solubility and pseudo-ternary phase diagrams. The optimized formulation (S-Eo3) was evaluated for use of spice oleoresins as curcumin bioenhancers. The oleophilic phase of curcumin containing SMEDDS formulations was then successfully modified by using bioactive oleoresins extracted from two Curcuma species, viz. C. longa (S-CL1) and C. aromatica (S-CA1). The curcumin content in S-Eo3, S-CL1 and S-CA1 were 69.6 ± 0.23 mg/g, 82.4 ± 0.62 mg/g and 88.8 ± 0.46 mg/g respectively. Thus, by the partial modification of oleophilic phase of SMEDDS with spice oleoresin (acting as bioenhancer) resulted in ∼88k improvement of curcumin aqueous solubility. The pharmacokinetic study in male Wistar rats showed that the relative bioavailability of curcumin in S-CL1 and S-CA1 were 26- and 29-fold vis-à-vis 22-fold in S-Eo3 compared to curcumin suspension. All the SMEDDS formulations were stable for three months as established by ICH guidelines.

description: Ground state properties of neutron rich even-even Be and C nuclei have been investigated using Relativistic Mean Field approach in co-ordinate space. The positions of the neutron drip line are correctly predicted for both the elements. The nucleus $^{14}$Be shows a two neutron halo but, contrary to expectation, $^{22}$C does not exhibit any halo structure. In carbon nuclei, N=16 comes out as a new magic number. The single particle level ordering observed in stable nuclei is found to be modified in neutron rich Be isotopes. Elastic partial scattering cross sections for proton scattering in inverse kinematics have been calculated using the theoretically obtained densities for some of the nuclei and compared with available experimental data. The total cross cross sections for elastic scattering have also been calculated for all the nuclei studied showing a large increase for the halo nucleus $^{14}$Be. The nuclei have also been investigated for deformation. The nuclei $^{10}$Be and $^{16,18,20}$C are observed to be deformed in their ground state.

description: Ausgehend von theoretischen Grundlagen, dokumentiert die vorliegende Arbeit ein Entwicklungsprojekt zur Förderung exekutiver Funktionen mittels Lyrik. Der Hauptakzent liegt dabei auf der gezielten Unterstützung von Kindern mit erhöhtem Förderbedarf. Exekutive Funktionen sind gemäss Brunsting (2011) für die Organisation des Alltags, das allgemeine Lernen und die erfolgreiche Selbstregulation erforderlich. Diese lassen sich, theoretischen Erkenntnissen zufolge, durch klare Strukturen gezielt fördern. Zugleich wird aufgezeigt, dass Lyrik Kindern einen unbeschwerten Zugang zur Sprache bietet und sich bestens für einen handlungs- und produktionsorientierten Unterricht eignet. Basierend auf der theoretischen Auseinandersetzung ist ein Produkt in Form eines Lyrikkoffers entstanden, welcher während einer Trainingsphase zum Einsatz kam. Die Auswertungen zeigten, dass ein gut strukturierter Unterricht, mit Einbezug dieses Lyrikkoffers, eine Förderung der exekutiven Funktionen für alle Kinder bewirkt.

description: Examination of a person who has been a victim of a physical or sexual assault may be very important for upcoming legal proceedings. In the context of a clinical forensic examination, physical findings are recorded and biological trace material is gathered and secured. Ideally, all forensic findings are documented in a detailed report combined with photographic documentation, which employs a forensic scale to depict the size of the injuries. However, the integrity of such forensic findings depends particularly on two factors. First, the examination needs to be conducted professionally to ensure that the findings are properly admissible as court evidence. Second, the examination should take place as soon as possible because the opportunity to successfully secure biological samples declines rapidly with time. Access to low-threshold clinical forensic examinations is not evenly provided in all member states of the European Union (EU); in some states, they are not available at all. As part of the JUSTeU! (Juridical standards for clinical forensic examinations of victims of violence in Europe) project, the Ludwig Boltzmann Institute for Clinical Forensic Imaging in Graz, Austria created (in cooperation with its international partner consortium) a questionnaire: the purpose was to collect information about support for victims of physical and/or sexual assault in obtaining a low-threshold clinical forensic examination in various countries of the EU. Our paper provides a summary of the responses and an overview of the current situation concerning provided clinical forensic services.

description: We report a first-principle study of the electronic and conduction properties of a quadruple-helix guanine wire (G4-wire), a DNA-derivative, with inner potassium ions. The analysis of the electronic structure highlights the presence of energy manifolds that are equivalent to the bands of (semi)conducting materials, and reveals the formation of extended electron channels available for charge transport along the wire. The specific metal-nucleobase interactions affect the electronic properties at the Fermi level, leading the wire to behave as an intrinsically p-doped system.

description: Categorical structures and their pseudomaps rarely form locally presentable 2-categories in the sense of Cat-enriched category theory. However, we show that if the categorical structure in question is sufficiently weak (such as the structure of monoidal, but not strict monoidal, categories) then the 2-category in question is accessible. Furthermore, we explore the flexible limits that such 2-categories possess and their interaction with filtered colimits.
