    In this Analysis, Lowy Institute International Security Program Director Rory Medcalf and Nonresident Fellow C. Raja Mohan argue that Chinese assertiveness and uncertainties about America’s role in Indo-Pacific Asia are causing middle powers to look for alternative approaches to regional security. The Analysis argues that enhanced security cooperation between Indo-Pacific middle powers should be extended to the creation of “middle-power coalitions” in the region. Key findings China’s assertiveness and uncertainties about America’s response are causing middle powers in Indo-Pacific Asia to looking beyond traditional approaches to security Cooperation between Indo-Pacific middle power coalitions would build regional resilience against the vagaries of US-China relations India and Australia are well placed to form the core of middle power coalition buildin

    Assessment of changes in ecosystem service delivery:a historical perspective on catchment landscapes

    Although the relationships between habitats and ecosystem services (ESs) have been acknowledged, investigating spatio-temporal change in these has received far less attention. This study assesses the influence of habitat changes on ES delivery across space and time, based on two time points some 60 years apart, 1946 and 2009. A 1946 aerial photo coverage of two catchments in Scotland was used to construct digital photo mosaics which were then visually interpreted and digitised to derive historic habitat maps. Using the Spatial Evidence for Natural Capital Evaluation (SENCE) mapping approach, the derived habitat maps were translated into ES maps. These were then compared with contemporary ES maps of the two catchments, using the same mapping methodology. Increases in provisioning ESs were associated with increases in intensively managed habitats, with reductions in supply capacity of other regulating and supporting ESs associated with loss of semi-natural habitats. ES delivery was affected not only by gross area changes in habitats over time, but also by changes in configuration and spatial distribution of constituent habitats, including fragmentation and connectivity. It is argued that understanding historic changes in ESs adds an important strand in providing baselines to inform options for current and future management of catchments

    The management of risk and investment in cell therapy process development: a case study for neurodegenerative disease

    Get PDF
    Cell-based therapies must achieve clinical efficacy and safety with reproducible and cost-effective manufacturing. This study addresses process development issues using the exemplar of a human pluripotent stem cell-based dopaminergic neuron cell therapy product. Early identification and correction of risks to product safety and the manufacturing process reduces the expensive and time-consuming bridging studies later in development. A New Product Introduction map was used to determine the developmental requirements specific to the product. Systematic Risk Analysis is exemplified here. Expected current valuebased prioritization guides decisions about the sequence of process studies and whether and if an early abandonment of further research is appropriate. The application of the three tools enabled prioritization of the development studie

    ObservaçÔes preliminares sobre a malformação em inflorescencias de mangueira (Mangifera indica L.) e fungo, alguns insetos e åcaro nelas encontrados

    Mango malformation, in the States of SĂŁo Paulo and Pernambuco, characterized by the transformation of the inflorescence into a compact mass of sterile flowers in adult trees and the production of thick vegetative shoots at the growing point or in the axil of a leaf in seedlings, is related to the mite Aceria mangiferae Sayed, 1946 (Acarina, Eriophyidae) and to the fungus Fusarium moniliforme subglutinans. The fungus is considered, although empirically, the main causative organism of the disease. Several insects were also collected from the mango inflorescences, namely: a caterpillar of Eupithecia sp ( = Tephroalystis) (Lepidoptera, Geometriidae, Hydriomeninae) damaging the flowers; large numbers of Frankliniella cubensis Hood, 1925 (Thysanoptera, Thripidae); and beetles belonging to the families Nitidulidae and Cryptophagidae.A malformação de inflorescĂȘncias e o superbrotamento de gemas terminais e axilares de mangueiras dos Estados de SĂŁo Paulo e Pernambuco sĂŁo relacionados com o ĂĄcaro Aceria mangiferae Sayed, 1946 (Acarina, Eriophyidae) e o fungo Fusarium moniliforme subglutinans, sendo ĂȘste Ășltimo considerado, empĂ­ricamente, como o principal agente causal da doença. Varios insetos associados Ă s inflorescĂȘncias de mangueiras foram coletados: lagarta de Eupithecia sp. (Tephroclystis), (Lepidoptera, Geometriidae, Hydriomeninae); Frankliniella cubensis Hood, 1925 (Thysanoptera, Thripidae); coleopteros pertencentes Ă s familias Nitidulidae e Cryptophagidae

    Search for CP Violation in the Decay Z -> b (b bar) g

    Full text link
    About three million hadronic decays of the Z collected by ALEPH in the years 1991-1994 are used to search for anomalous CP violation beyond the Standard Model in the decay Z -> b \bar{b} g. The study is performed by analyzing angular correlations between the two quarks and the gluon in three-jet events and by measuring the differential two-jet rate. No signal of CP violation is found. For the combinations of anomalous CP violating couplings, h^b=h^AbgVb−h^VbgAb{\hat{h}}_b = {\hat{h}}_{Ab}g_{Vb}-{\hat{h}}_{Vb}g_{Ab} and hb∗=h^Vb2+h^Ab2h^{\ast}_b = \sqrt{\hat{h}_{Vb}^{2}+\hat{h}_{Ab}^{2}}, limits of \hat{h}_b < 0.59and and h^{\ast}_{b} < 3.02$ are given at 95\% CL.Comment: 8 pages, 1 postscript figure, uses here.sty, epsfig.st

    Search for the glueball candidates f0(1500) and fJ(1710) in gamma gamma collisions

    Full text link
    Data taken with the ALEPH detector at LEP1 have been used to search for gamma gamma production of the glueball candidates f0(1500) and fJ(1710) via their decay to pi+pi-. No signal is observed and upper limits to the product of gamma gamma width and pi+pi- branching ratio of the f0(1500) and the fJ(1710) have been measured to be Gamma_(gamma gamma -> f0(1500)). BR(f0(1500)->pi+pi-) < 0.31 keV and Gamma_(gamma gamma -> fJ(1710)). BR(fJ(1710)->pi+pi-) < 0.55 keV at 95% confidence level.Comment: 10 pages, 3 figure

    Influence of storage conditions and packaging materials on some quality attributes of water yam flour

    Get PDF
    The study investigated some quality attributes of water yam flour stored in three packaging materials [high and low density polyethylene and plastic container] under different storage conditions [relative humidity (36%, 56%, 75% and 96%), temperature (25±2, 35±2 and 45±2 °C)] for 24 weeks. The functional properties, proximate composition and microbial load of the samples were evaluated at 4 weeks interval. Significant differences (p<0.01) were observed for proximate composition, functional properties and microbial load of the samples during storage. The interactive effect of storage conditions and packaging materials was significant (p<0.01) on proximate composition and pasting properties (except trough viscosity). The yam flour samples were still shelf stable after the 24 weeks of storage
