It is universally understood that postharvest losses are high, particularly in less developed economies, and that this is an issue of keen interest to researchers, practitioners and policy makers alike. Postharvest losses are defined by COMCEC as food damage or degradation of food during different stages of the food supply chain that are incurred between the farm-gate and prior to retail and consumption. Highlights of this report. • Clear evidence of substantial postharvest losses across all Members and commodity groups and these are similar to those reported in non-OIC Member Countries. Figures are estimates though. • Pockets of high physical losses identified: e.g., fruit and vegetables, root and tuber crops and meat and meat products • High economic losses for cereals and fish and fish products • Nutrition losses were rarely reported but for cereals in Sub-Saharan Africa losses could be equivalent to the annual caloric requirement of 48 million people • Weak policy support to eff...

Cells defence against stresses that can cause DNA damage (single-strand breaks, double-strand breaks) is crucial in safeguarding the integrity of the genome and the survival of the organism as a whole. One of the genes that plays a pivotal role in maintaining the stability of the genome in humans is p53, which encodes its product p53 protein. The regulation of p53 activation is extremely complex, and molecular cell biology has gathered parts and pieces of the whole pathway. Mental intuition of this complex regulation is challenging; therefore, it requires a different method to quantitatively model and analyse to enhance the current understanding. This thesis has attempted to create two quantitative models of the mechanisms that regulate p53 basal levels and its appropriate activation as a stress response in deciding cell fate by either cell cycle arrest (to stop proliferation of DNA-damaged cells) or apoptosis (programmed cell death) to eliminate damaged cells. In the first part of ...

Schools and Sustainable Urban Mobility An approach paper with special reference to textbook analysis, 2017

Schools and Sustainable Urban Mobility: An approach paper with special reference to textbook analysis April 2017 Introduction The safety of school going children and their modes of mobility should be an important element in a city’s transportation plans. Schools generate a substantial proportion of the trips in any city. While safety is a paramount concern, the modes by which these school trips are made, must also be considered in the city’s transportation planning. Close to half the population of a city is likely to be directly concerned with how children go to school, and so the school community is a prime stakeholder in urban transportation planning. It is essential that cities provide a platform for the needs of schools to be reflected in transportation systems and projects, including facilities for public transport, walk and cycle. Equally important is the students’ learning in relation to sustainable mobility. A city’s transition to better mobility systems is likely to be easier if the citizenry is well-informed about the need for change, has supportive attitudes and is prepared to take the actions needed for the transition. Schools can help children learn about sustainable mobility. Schools can also be the vehicle for engagement of a much wider community of people in the city. This paper is in two parts. The first part presents initial thoughts on how to approach the domain of schools and sustainable mobility, and the web of actors and actions needed. The second part, which is more elaborate, presents a rapid analysis of textbooks of NCERT, Maharashtra and Gujarat, that assesses the extent and nature of content related to the topic of ‘transportation’. The purpose is to look at the status of content related to the topic of transport in the textbooks and open up the discussion for further ideas to strengthen curricular support/ interventions. We present a framework of desirable learning outcomes in relation to ‘sustainable mobility’. Assessed against this desired learnings outcomes framework, there are considerable gaps in the comprehensiveness and continuity of content related to in the textbooks we have reviewed. There are some good examples of both content and presentation in some textbooks, notably in the Maharashtra textbooks. Much work is needed on all fronts – in creating transportation systems and facilities that are schoolfriendly, developing and facilitating forums where the transportation needs of schools can be discussed, and for schools to provide learning opportunities for school children in relation to sustainable mobility. We hope this paper may be a useful input for discussions on this topic among policy makers, local governments, associations of schools and parents, NGOs and CSR organizations, education and transportation professionals, and SUM Net. We request readers to get in touch with us at the email addresses below with their views, experiences and suggestions for further work in the schools and sustainable mobility domain.

As a developing country, Ghana appears ready to face the challenges of effective digital resources management. The country has developed programmes and a national policy on information and communication technologies (ICTs) for accelerated development. However, Ghana does not appear to be effective in managing or preserving digital cultural heritage resources. An interpretive case research design involving 27 semi-structured interviews with key stakeholders from 23 institutions was used to explore the various contextual factors influencing the management and preservation of digital cultural heritage resources (or DPM). Rogers’ (2003) “diffusion of innovation” (DOI) theory and Davies’ (2000) “policy, strategy and resources” (PSR) troika model provided a basis for a preliminary model of factors to guide the research. This study extends Information Systems (IS) research involving DOI theory and the PSR troika model into a developing country context.

Cold gas-dynamic spray is a solid-state materials consolidation technology that has experienced successful adoption within the coatings, remanufacturing and repair sectors of the advanced manufacturing community. As of late, cold spray has also emerged as a high deposition rate metal additive manufacturing method for structural and nonstructural applications. As cold spray enjoys wider recognition and adoption, the demand for versatile, high-throughput and significant methods of particulate feedstock as well consolidated materials characterization has also become more notable. In order to address the interest for such an instrument, nanoindentation is presented herein as a viable means of achieving the desired mechanical characterization abilities. In this work, conventionally static nanoindentation testing using both Berkovich and spherical indenter tips, as well as nanoindentation using the continuous stiffness measurement mode of testing, will be applied to a range of powder-base...

Fischer-Tropsch (FT) technology is simply defined as the means to convert syngas to a wide range of hydrocarbon products including paraffins, olefins, oxygenates, etc. Interest in FT synthesis is increasing rapidly due to a number of factors including demand of cleaner fuel (low Sulphur, low aromatics), improvement in FT technology and the need to monetize stranded natural gas resources. Hence, there is a strong incentive to further optimize the reactions in a GTL plant so that the overall cost can be reduced. In this study, the overall GTL process was simulated using Aspen HYSYS v8.6. The impact of different parameters on the performance of syngas unit, FTS unit and the overall process were studied. The main objective is to optimize all the main reactions involved in GTL process as well as to increase fraction of desired product. To achieve this, all the important reactions were modelled using kinetic approach obtained from literature and kinetic reactors were used. The Auto Thermal Reactor (ATR) was modelled as CSTR and PFR in HYSYS with kinetic data given by Xu,Froment et al. and D.L Hoang et al. [11], [22]. The main objective function was to increase conversion of reaction and to produce low H2:CO ratio in syngas. Three configurations were proposed to compare the contact model of the ATR using different reactors. CSTR was observed to produce syngas with suitable H2:CO ratio for FTS. Staging of ATR with dossification of feed between stages was simulated however it did not show any improvement on conversion or H2:CO ratio. The FT reactor with cobalt based catalyst was modelled as PFR with kinetic data from Iglesia et al.[27] A few parameters were varied to observe the effect on product distribution and overall conversion. In case 3, the effect of varying void fraction in FTR was studied and the optimal value was recorded. Case 4 explored the effect of multiple stage FTR configuration. Staging of FTR recorded a higher overall conversion and product distribution also improved. An optimal FTR configuration was proposed and showed an even higher conversion compared to the multi stage FTR and an improved product distribution. Some other process parameters were also investigated such as the inlet temperature of ATR and steam:carbon ratio in pre-reformer. Optimization of both parameters showed improvement in the syngas produced. Lower H2:CO ratio of syngas was observed by increasing inlet temperature of ATR and reducing steam:carbon ratio. The optimal GTL plant configuration was proposed at the end of this study.
