Planning for resilience, embedding risk

Papers presented virtually at the 41st International Southern African Transport Conference on 10-13 July 2080Planning for the future existence and goals, requires a concrete element of resilience to enable the transport industry to contribute effectively to contributing to the economic context of any country or region. The advent of technology in transport (TransportTech) requires a human intervention to be resilient in time of unpredictable change in environmental settings, economic patterns and socio-economic activity. All of these culminate in embedded risk within our transit infrastructure, with collected data and the users who interact with it. There is a case for adoption and/change to re-use processed materials as re-usable part on the value chain of the infrastructure rebuilds, offer @home safety for individuals and group to transit between start and destination and transit innovation for road, sea and air navigation. Key Thematics: 1. 3 radical scenarios of the future, unlocking human discomfort and risk. 2. Modelling risk in a dynamic and unpredictable transport universe. 3. What does AI bring to the table

Nitrogen effect on zinc biofortification of maize and cowpea in Zimbabwean smallholder farms

Agronomic biofortification of crops with zinc (Zn) can be enhanced under increased nitrogen (N) supply. Here, the effects of N fertilizer on grain Zn concentration of maize (Zea mays L.) and cowpea (Vigna unguiculata L.) were determined at two contrasting sites in Zimbabwe over two seasons. All treatments received soil and foliar zinc‐sulphate fertilizer. Seven N treatments, with three N rates (0, 45, and 90 kg ha−1 for maize; 0, 15, and 30 kg ha−1 for cowpea), two N forms (mineral and organic), and combinations thereof were used for each crop in a randomized complete block design (n = 4). Maize grain Zn concentrations increased from 27.2 to 39.3 mg kg−1 across sites. At 45 kg N ha−1, mineral N fertilizer increased maize grain Zn concentration more than organic N from cattle manure or a combination of mineral and organic N fertilizers. At 90 kg N ha−1, the three N fertilizer application strategies had similar effects on maize grain Zn concentration. Co‐application of N and Zn fertilizer was more effective at increasing Zn concentration in maize grain than Zn fertilizer alone. Increases in cowpea grain Zn concentration were less consistent, although grain Zn concentration increased from 39.8 to 52.7 mg kg−1 under optimal co‐applications of N and Zn. Future cost/benefit analyses of agronomic biofortification need to include information on benefits of agro‐fortified grain, complex farmer management decisions (including cost and access to both N and Zn fertilizers), as well as understanding of the spatial and site‐specific variation in fertilizer responses

N,N'-diisopropylthiourea and N,N'-dicyclohexyl-thiourea zinc(II) complexes as precursors for the synthesis of ZnS nanoparticles

The single X-ray crystal structures of zinc (II) complexes of N,N'-diisopropylthiourea and N,N' dicyclohexylthiourea weredetermined.These complexes, similar to other alkylthioureas, were found to be effective as precursors for the preparation of hexadecylamine-capped ZnS nanoparticles. The complexes are air-stable, easy to prepare and inexpensive. They pyrolyse cleanly to give high-quality ZnS nanoparticles, which show quantum confinement effects in their absorption spectra and close to band-edge emission. Their broad diffraction patterns are typicalof nanosized particles while their transmission electronmicroscopy images showed agglomerates of needle-like platelet nanoparticles
