Full textAbstract:
Since 2000, Morocco has launched important institutional and economic reforms based on strategies to correct market failures in important sectors of the economy. These strategies have included tax exemptions and other financial incentives, facilitating access to land and simplifying administrative procedures, and launching major public infrastructure projects, all of which have combined to create a new investment dynamic in strategic sectors such as agriculture, industry, and energy. These efforts have affected many sectors: the Azur Vision 2020 plan for tourism, the Green Morocco Plan for agriculture, the Halieutis 2020 Plan for fishing, Maroc Plus Export for export, the Emergence Plan (2005) for industry followed by the National Pact for Industrial Emergence, 2009-2015 and the new Industrial Acceleration Plan, 2014-2020. For example, to support the new Industrial Acceleration Plan, the government has provided a grant, a financial support of about 2% of GDP over 6 years. The government has also offered ad hoc support to attract foreign investors in large private projects likely to generate significant positive externalities. One example is the project to set up a Renault Company plant in Tangiers, which aims to produce and export 400,000 cars per year (World Bank, 2017).This note highlights the industrial sectors that can offer the best potential for growth, attract private investors and contribute to the creation of decent jobs. It will also identify ways to accelerate investment in Morocco. These industrial investments may include purely private investments or those made with the support of international financial institutions. The note analyzes investment and sectoral integration opportunities using the input model (outputs and employment elasticity indicators), the evaluation of the industrial acceleration plan, and sets out the measures taken by the CVE to promote VSEs. Only one classic sector is selected is highlighted for their investment potential and their commitment to reform in the sectors. It is the food industry.The note follows the diagram below:1) An introduction to the economic, political and social frameworks, including key indicators 2) A sector analysis to identify one to three sectors that are likely to be the subject of accelerated investment and in which reforms will have a particularly high chance of improving the business and investment climate and having an impact on development. 3) A mapping of the most relevant initiatives, technical assistance, grants and loans, and investments by donors and other stakeholders, such as development finance institutions. In the selected sector(s).4) An analysis of the existing reform agenda in the respective sector(s) and the identification of areas where there is a high likelihood of effective cooperation to support the implementation of these reforms.

Full textAbstract:
In this paper we describe how fuzzy reasoning can assist an automated program understanding/fault localization tool with program understanding tasks. We are developing such a tool called BUG-DOCTOR, which is based on a blackboard framework. A fuzzy reasoner is proposed as a component for one of its knowledge sources, the Plan Processor. The Plan Processor retrieves a set of program plans from a plan library using indices called signatures. These plans are candidates for matching against the code we are trying to understand. The fuzzy reasoner will support the Plan Processor with the task of ranking the retrieved plans in order of similarity to the target code. The most highly ranked plan can then be used for the complex plan/code matching required for automated program understanding. Experiments with a fuzzy reasoning prototype are promising, and we believe that this approach to plan processing may eliminate the need for exhaustive plan library searches. The success of the fuzzy reasoning approach could lead to automated program understanders that scale up for use on large software systems from a variety of problem domains.

Full textAbstract:
Modern data processing systems require optimization at massive scale, and using machine learning to optimize these systems (ML-for-systems) has shown promising results. Unfortunately, ML-for-systems is subject to over generalizations that do not capture the large variety of workload patterns, and tend to augment the performance of certain subsets in the workload while regressing performance for others. In this paper, we introduce a performance safeguard system, called PerfGuard , that designs pre-production experiments for deploying ML-for-systems. Instead of searching the entire space of query plans (a well-known, intractable problem), we focus on query plan deltas (a significantly smaller space). PerfGuard formalizes these differences, and correlates plan deltas to important feedback signals, like execution cost. We describe the deep learning architecture and the end-to-end pipeline in PerfGuard that could be used with general relational databases. We show that this architecture improves on baseline models, and that our pipeline identifies key query plan components as major contributors to plan disparity. Offline experimentation shows PerfGuard as a promising approach, with many opportunities for future improvement.

In various networks, anomaly may happen due to network breakdown, intrusion detection, and end-to-end traffic changes. To detect these anomalies is important in diagnosis, fault report, capacity plan and so on. However, it?s challenging to detect these anomalies with high accuracy rate and time efficiency. Existing works are mainly classified into two streams, anomaly detection on link traffic and on global traffic. In this paper we discuss various anomaly detection methods on both types of traffic and compare their performance.

The reconfiguration debate has dominated the NHS over the summer with Conservative leader David Cameron promising a 'bare knuckle fight' over district general hospitals under threat from service closure. With the focus clearly on the need for service change, it is timely for the College to restate its policy on the provision of trauma care. We are calling for a critical examination of those centres currently providing trauma care and a national plan for the identification of major specialist trauma centres to provide the best care to injured patients.

Full textAbstract:
Automated conceptual design often shows significant promise for generating conceptual solutions automatically through searching and synthesizing known principle solutions for a desired function. However, existing automated conceptual design systems lack an efficient heuristic search strategy and a knowledge-based planning mechanism, which lead to less chance of finding promising principle solutions within a limited time. This article proposes a novel semi-heuristic planning approach for automated conceptual design which comprises two successive steps, i.e. DESIGN PLAN and DESIGN COMBINATION. During the stage of DESIGN PLAN, the planning-graph technique is employed to extract a design plan from a planning graph, which is composed of various principle solution clusters. Under the guidance of the design plan, in the second stage, DESIGN COMBINATION combines compatible principle solutions from the principle solution clusters in the design plan until finding promising conceptual solutions. A prototype system and design case illustrate that the proposed semi-heuristic planning approach can successfully achieve an automated conceptual design synthesis.

Full textAbstract:
Canadian drug plan pricing of generic drugs is in a state of flux, with different plans adopting different approaches. The manner in which public plans pay for generic drugs can affect five policy goals: low generic drug prices, security of the drug supply, a reliance on reimbursement rules (thereby avoiding the need for drug plan managers to exercise discretion over reimbursement levels), low administrative burden and finally, the provision of adequate incentives for generics to enter the market. We review five pricing mechanisms: maximum prices, tiered pricing, tendering, benchmarking and pharmacy competition. We examine international evidence on the success of the first three of these. We conclude with an assessment of promising reimbursement approaches.

Modern molecular biology, biochemical, and chemical techniques have made it possible to identify individual natural products that possess pharmacological activity from medicinal plants. While approximately 50% of all new FDA-approved small molecule therapeutics in the past 40 years were natural products or natural product analogs, challenges including limited natural resources and the difficulty of solving the total synthesis or semi-synthesis of natural products has limited our ability to harness the full diversity of chemical structures provided by nature to treat human diseases. One solution to these challenges is the elucidation of plant specialized metabolite biosynthetic pathways. Identifying and characterizing the enzymes involved in specialized metabolite biosynthesis will provide insight into the evolution of enzymes performing interesting chemistries and provide new tools for the enzymatic production of therapeutically promising natural products. The goal of this dissertation is to explore the aspects of both medicinal chemistry and the elucidation of biosynthetic pathways that can contribute to the development of novel therapeutics. First, we analyzed the structure-activity relationship of analogs of the the flavonoid icariin and identified analogs with improved potency in inhibiting human phosphodiesterase-5. We subsequently identified and characterized a novel flavonoid prenyltransferase and O-methyltransferase from the medicinal herb Epimedium sagittatum that is known to produce many bioactive prenylated and methylated flavonoids.

Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Liviidae) is an important vector of Huanglongbing (HLB), a phloem-restricted bacterial disease that hammered citrus industry worldwide. To date, there is no chemical cure for the infected citrus crops. Prevention is therefore far more important than cure concerning HLB. Taiwan has established healthy seedling system, which meant to cut off HLB transmission via grafting. Nevertheless, citrus orchids are vulnerable to HLB by insect vector, ACP. Chemical control is the common way to deal with ACP, but excessive use of insecticide not only give rise to resistance, but also damage environment. Improvement of current monitor methods may lead to better understanding of ACP colony distribution in citrus orchards. With enhanced monitor method, the use of insecticide will be more efficient. Our goal is thus analyzing volatile organic compounds (VOCs) from citrus young leaves, and by combining VOCs that attracts ACP, we hope to find mixtures that can be used along with yellow sticky traps. We first looked into ACP preference of young leaves on different citrus cultivars. Meanwhile, we analyzed VOCs from young leaves and compared with the result of ACP preference. Ponkan is the most preferred cultivar, and the content of its young leaves also showed clear difference with other cultivars. Then, based on the information above, we formulated two mixtures, artificial attractant 1, and 2. After preference tests using Y-tube olfactometer, even 63.9% of ACP chose artificial attractant 2, there is no analytic significant difference. The results are negative though, still prove the possibility of making mixtures that attract ACP based on VOCs from citrus young leaves.

Full textAbstract:
This case study examines the challenge of implementing survivorship care plans (SCPs), which are intended to document cancer treatment, make recommendations for future care, and facilitate cancer survivors’ care transitions. It describes SCPs’ policy context and offers as a case study the SCP implementation experiences of a university-based hospital and an integrated delivery system. It recommends implementation science as a next step in developing more definitive evidence of SCPs’ effectiveness, which is determined in part by implementation. It also describes promising SCP implementation studies that take into account stakeholders’ perspectives on SCP implementation and plan to leverage findings for future studies in which implementation is examined as a determinant of SCP effectiveness. It recommends future research that uses stakeholder perspectives to develop systems for SCP implementation, adapts SCPs to fit cancer programs’ unique contexts, and investigates the implementation of survivorship care programs of which SCPs are just one component.

Full textAbstract:
The objective of this chapter is to develop a process perspective on ambidexterity that not only informs the specific research on reconciling the contradictory forces of exploration and exploitation, but also the broader theory on how organizations experience and address paradoxical tensions. We distinguish three stages of paradox management within ambidextrous organizations. During the initiation stage, organizational actors identify the paradoxical tensions and develop a strategic plan to address them. In the subsequent contextualization stage, they put the organizational structures, cultures, and processes in place, with which to address the paradox. During the implementation stage, the organizational actors manage the paradoxical tensions in their day-to-day activities. By comparing the structural, contextual, and sequential pathways that organizations take to navigate these stages, we review and expand current theorizing on exploration–exploitation tensions and derive promising avenues for future ambidexterity and paradox research.

Chapter 5 describes how economic decline led to an ideological shift in America. Trump was good at promising things that resonated with the public’s discontent. This chapter shows how he did this, particularly insofar as his economic plan is concerned. This is a story about the rise of neoliberalism as the cure for what ailed Americans and the American economy. Neoliberal ideology is a conservative approach to policymaking that touts the virtues of small government, low taxes, less regulation, and reduced welfare spending. It involves a taken-for-granted paradigm—a set of assumptions—about how the economy works, as well as specific policy recommendations derived from it. It also involves a variety of public sentiments or values deeply rooted in American culture about the virtues of small government. These sentiments and others provided raw materials with which Trump effectively fabricated catchy frames to garner public support for his policy ideas.

Following on from Chapter 5, this chapter outlines the final three stages in the process of designing and delivering arts in health interventions. It provides a step-by-step guide for how to turn an idea into action and implement and evaluate interventions. It shows how to undertake an effective pilot project, design an evaluation that captures its impact as well a supporting its future development, assess its likelihood of success on a larger scale, draw up a case for support for stakeholders and funders, finetune the intervention to make it more efficient and economical, develop an ongoing audit process, create a manual of the intervention to enable its replication elsewhere, scope opportunities for expansion, and plan for continuous innovation to ensure it stays current and appealing for participants. These steps will provide the springboard for a promising intervention to be launched and scaled in a sustainable way.

Sugar-sweetened beverage taxation in the Region of the Americas. Pan American Health Organization, 2021. http://dx.doi.org/10.37774/9789275122990.
Full textAbstract:
Sugar-sweetened beverage excise taxes are an effective evidence-based noncommunicable diseases (NCD) prevention policy. Along with tobacco and alcohol excise taxes, they are a tool to attain the Sustainable Development Goals, and are recommended by the World Health Organization to modify behavioral risk factors associated with obesity and NCDs, as featured in the WHO Global Action Plan. Taxes on sugar-sweetened beverages have been described as a triple win for governments, because they 1) improve population health, 2) generate revenue, and 3) have the potential to reduce long-term associated healthcare costs and productivity losses. Taxation of sugar-sweetened beverages has been implemented in more than 73 countries worldwide. In the Region of the Americas, 21 PAHO/WHO Member States apply national-level excise taxes on sugar-sweetened beverages and seven jurisdictions apply local sugar-sweetened beverage taxes in the United States of America. While the number of countries applying national excise taxes on sugar-sweetened beverages in the Region is promising, most of these taxes could be further leveraged to improve their impact on sugar-sweetened beverages consumption and health. This publication provides economic concepts related to the economic rationale for using sugar-sweetened beverage taxes and the costs associated with obesity; key considerations on tax design including tax types, bases, and rates; an overview of potential tax revenue and earmarking; evidence on the extent to which these taxes are expected to impact prices of taxed beverages, the demand for taxed beverages, and substitution to untaxed beverages; and responses to frequent questions about the economic impacts of sugar-sweetened beverage taxation.

This essay addresses the relevance of genetic data, including gene-by-environment interactions, to criminal responsibility and sentencing. After describing the criminal law’s implicit psychology and criteria for responsibility, it considers the present and future contributions genetics may make. It suggests that, at present, genetics should not play a large role in the adjudication of individual cases unless it translates directly into the law’s folk psychological criteria for responsibility, which it seldom does. Future discoveries may increase the usefulness of genetics to rational adjudication, however. The role of genetics at sentencing may be somewhat more promising, especially concerning the prediction of future behavior.

Chronic diseases are the leading causes of mortality worldwide. Their prevalence and disruptive potential warrant an understanding of the factors that influence adjustment to chronic illness. Gender and gender-related processes play an important role in psychosocial and physical adjustment to chronic disease. In this chapter, the authors summarize theoretical frameworks relevant to the role of gender in adjustment to chronic illness, with a particular focus on the experience of cancer. Although theoretically guided research is limited, theoretical frameworks suggest promising avenues of inquiry for characterizing the role of gender and adjustment to cancer and the development of associated interventions.

Full textAbstract:
AbstractInvasive species and their management represent a complex issue spanning social and ecological systems. Invasive species present existing and potential threats to the nature of ecosystems and the products and services that people receive from them. Humans can both cause and address problems through their complex interactions with ecosystems. Yet, public awareness of invasive species and their impact is highly uneven, and public support for management and control of invasive species can be variable. Public perceptions often differ markedly from the perspectives of concerned scientists, and perceptions and support for management are influenced by a wide range of social and ecological values. In this chapter, we present a broad survey of social science research across a diversity of ecosystems and stakeholders in order to provide a foundation for understanding the social and cultural dimensions of invasive species and plan more effective management approaches. This chapter also addresses tribal perspectives on invasive species, including traditional ecological knowledge, unique cultural dimensions for tribes, and issues critical to engaging tribes as partners and leaders in invasive species management. Recognizing that natural resource managers often seek to change people’s perceptions and behaviors, we present and discuss some promising approaches that are being used to engage human communities in ways that empower and enlist stakeholders as partners in management.

In order to provide a consistent direction to long-term R&D activities, the Korea Atomic Energy Commission (KAEC) approved a long-term development plan for future nuclear reactor systems which include sodium cooled fast reactor (SFR) and very high temperature reactor (VHTR) on December 22, 2008. The SFR system is regarded as a promising technology to perform actinide management. The final goal of the long-term SFR development plan is the construction of an advanced SFR demonstration plant by 2028. The nuclear hydrogen project in Korea aims at designing and constructing a nuclear hydrogen demonstration system by 2022 to demonstrate its hydrogen production capability. This paper summarizes the overall long-term project plans for SFR and VHTR technology development and explains results of detailed design studies with supporting R&D activities.

This paper examines how the generation of entrepreneurs 50+ should be addressed in order to raise their interest for improving their skills, and how young entrepreneurs and students can profit from the seniorpreneurs’ expertise in production processes and market knowledge as well as from their networks. To promote the promising synergies arising from the collaboration of young and elderly entrepreneurs a project was initiated that combines an integrated product development with business plan design support. Prospective entrepreneurs with industrial experience (seniorpreneurs) and innovative product ideas are matched with multidisciplinary student teams to generate a going-to-market prototype as a basis for starting new businesses. From the standpoint of research and development the balance is excellent with several promising product innovations and business plans for entrepreneurial implementation. The perspective of science and technology transfer demands an urgent desideratum to bring the accumulated value potential into the market.

Full textAbstract:
Straddling the Arctic Circle on the Chukchi Sea, the Northwest Alaska Native Association (NANA) region constitutes the boundaries of the Northwest Arctic Borough (NWAB), and has a population of about 7,600 people. The high cost of energy in the NANA region is one of the leading threats to the long term sustainability and well-being of the region. As a result of complex and lengthy logistics, the region has some of the highest energy prices in the nation. In addition to the cost of fossil fuels, NANA region residents are increasingly aware of the effects of greenhouse gases on climate change and the resulting coastal erosion along the Chukchi Sea. NANA Regional Corporation, along with other regional stakeholders, has developed a regional integrated energy plan. This approach includes community specific energy options analyses, benefit-cost analyses of competing alternatives, analysis of available literature and past experiences, surveying of professional opinion, and a regional energy summit that involved multiple stakeholders. Since the mid-1990s, the NANA region has been an Alaska leader in promoting and developing renewable energy resources with wind turbine installations in Kotzebue and Selawik. Promising wind energy potential is under investigation in several more communities, and other known energy resources being studied include geothermal, small-scale hydropower, and a substantial biomass potential in the upper Kobuk River area. Also under investigation are stranded natural gas sources and even solar PV installations for some communities. Energy security in the region will be achieved by a combination of infrastructure improvement and development of appropriate energy technologies, both traditional and renewable. It is the vision of NANA region stakeholders to be 75% reliant on regionally available energy resources for heating and electric generation purposes by the year 2030, and to decrease the need for transportation fuel imported into the region by 50% by the year 2030. As part of this vision, imported fossil fuels would remain as emergency/back-up fuel only. With proper planning, a synergy can be developed between different energy sources and uses, with the composition of the optimal ‘energy-mix’ custom-tailored for each community in the NANA region. The energy planning process will be conducted with the understanding that the optimum mix may change over time.

Full textAbstract:
After 60 years and more than $1.9 trillion of investments, the United States has developed one of the world’s most advanced highway and aviation systems. However, these transportation systems are now at a gridlock. To reduce the congestion and increase efficiency of America’s regional transportation, rail transit should be considered as a promising, long-term solution. The recent stimulus package provides planners an opportunity to reconsider the potentials of regional passenger rail network, especially the high speed rail system. After examining the development history and current condition of America’s passenger rail network, the paper focuses on Amtrak’s Northeast Corridor (NEC) and proposes three different improvement plans that can increase travel speeds and attract more ridership: (1) return the corridor to a state of good repair; (2) construct a new dedicated High-Speed Rail track; and (3) develop a multimodal-shared and connected corridor. Each plan has its advantages and drawbacks, and measuring the extent of each plan’s benefits and costs is known to be challenging. To evaluate these plans, the paper utilizes a non-traditional cost-benefit analysis method which considers changes in ridership, life-cycle costs as well as each plan’s economic and environmental impacts (negative or positive). It is found that returning the existing corridor to a state of good repair is the most efficient improvement plan in near term.

Abstract Obtaining and analyzing customer and product information from various sources has become a top priority for major competitive companies who are striving to keep up with the digital and technological progress. Therefore, the need for creating a crowdsourcing platform to collect ideas from different stakeholders has become a major component of a company’s digital transformation strategy. However, these platforms suffer from problems that are related to the voluminous and vast amount of data. Different large sets of data are being spurred in these platforms as time goes by that render them unbeneficial. The aim of this paper is to propose a solution on how to discover the most promising ideas to match them to the strategic decisions of a business regarding resource allocation and product development (PD) roadmap. The paper introduces a 2-stage filtering process that includes a prediction model using a Random Forest Classifier that predicts ideas most likely to be implemented and a resource allocation optimization model based on Integer Linear Programming that produces an optimal release plan for the predicted ideas. The model was tested using real data on an idea crowdsourcing platform that remains unnamed in the paper due to confidentiality. Our prediction model has proved to be 92% accurate in predicting promising ideas and our release planning optimization problem results were found out to be 85% accurate in producing an optimal release plan for ideas.

Full textAbstract:
Assembly sequence planning is an engineering problem that has been of great interest in the manufacturing field at the macro-scale. As more complex assemblies are desired at the micro and nano scales it is no longer feasible for human beings to plan and execute the production of these systems. A promising algorithm that allows optimization of assembly sequence plans that has been developed is called the Breakout Local Search. One drawback of this algorithm is its inability to consider the need for intermediate sub-assemblies to generate feasible solutions. Here an expansion to the BLS algorithm, called the Sub Assembly Generating BLS (SABLS) algorithm, is proposed. The fitness function of this new algorithm is also tailored to the specific constraints and motion primitives for a micromanipulation test-bed allowing for its use in microassembly applications. It is shown that the proposed algorithm is capable of generating optimized solutions that can be assembled with this limited degree of freedom system.

Abstract The Miocene Gachsaran Formation across Onshore Abu Dhabi and Dubai possesses high potential of generating shallow biogenic gas. A dynamic model and field development plan generated based on a detail G&G analysis to understand and evaluate its capability as promising gas resources. Specific approaches and workflow generated for volumetric and dynamic reservoir model capable of defining the most viable development strategy of the field from both an economic and technical standpoint. The proposed workflow adapts also the development plan from single pad-scale to full field development plan. A fine-grid field-scale with more than hundreds of Pads covering the sweet spot area of three thousands of square kilometers including structure, reservoir properties built based on existing vertical wells, newly drilled horizontal wells and seismic interpretation. In this paper, a robust workflow for big and complex unconventional biogenic gas reservoir modeling and simulation technique have been developed with hydraulic fracture and stimulated area created through LGR. Independent workflows generated for the adsorbed gas in place calculation, desorption flow mechanism, and Pads field development plan. An accuracy on in place calculation, desorption flow mechanism and Pseudo steady state flow through direct and indirect total gas concentration measured using (1) Pressurize core and sorption isotherm capacity experiment, (2) Langmuir /BET function and Vmax scaling curves for each grid cells, and (3) Gas concentration versus TOC relationship. Field development plan for unconventional shallow biogenic gas reservoirs is possible only if a communication network created through hydraulic fractures connects a huge reservoir area to the wellbore effectively. A complete workflow presented for modeling and simulation of unconventional reservoirs, which in-corporates the characterization of hydraulic fracture and their interaction with reservoir matrix. Dual porosity model has been constructed with accurate in place calculation through scaling the Langmuir function and calculation Vmax for each grid cell of the full field model, The single Pad design approach in the development plan has exhibited great advantages in terms of improvement in the quality and flexibility of the model, reduction of working time with the same Pad model design which is adapted for the full field development plan. The proposed unconventional modeling and field development plan workflow provides an efficient and useful unconventional dynamic model construction and full field development planning under uncertainty analysis. Minimizing the uncertainty in place calculation and production forecasting for unconventional reservoirs necessitates an accurate direct and indirect data measurement of gas concentration and flow mechanism through the laboratory measurement. Field development plan for unconventional reservoirs is possible only if fracture network can be created through hydraulic fractures that connects a huge reservoir area to the wellbore effectively through pad completion.

Full textAbstract:
Mitigation of earthquake loads by seismic isolation technology is very promising for enhanced safety and economy of the next generation nuclear reactors, through rationalized and simplified design of structures, systems and components. The horizontal base isolation with laminated rubber bearings is a proven technology and its application has been widely spread including nuclear facilities. On the other hand, significantly increased benefit of mitigated seismic loads is expected with three-dimensional (abbreviated 3D) seismic isolation, since the earthquake loads are inherently three-dimensional and the vertical component of the earthquake load sometimes plays an important role in the structural design of reactor components. From these points of view, a research project has been undertaken for the development of 3D seismic isolation technology, under the sponsorship of the Ministry of Economy, Trade and Industry of the Japanese government. It was presented in a former conference that two types of 3D seismic isolation systems were applicable to the next generation nuclear power plants. One is 3D base isolation of a whole nuclear island, and the other is a vertical isolation system for main components with horizontal base isolation system. Among a number of proposed concepts, three were promising ideas for the 3D base isolation system (or device), i.e., “hydraulic 3D base isolation system”, “independent cable reinforced rolling-seal air spring”, and “rolling seal type air spring”. Then the last idea, i.e., “rolling seal type air spring”, was selected from above three ideas for further development. In this paper, current status of this R&D project are firstly shown. Next, the performance requirements for 3D isolation system and devices are shown. Then the developing targets for 3D isolation technology are shown. Furthermore, future plan of the project is provided.

Full textAbstract:
Current US transportation sector mainly relies on liquid hydrocarbon derived from petroleum and about 60% of the petroleum consumed is from areas where supply may be disturbed by regional instability. This has led to serious concerns on global warming and energy security. To address these issues, numerous alternative energy carriers have been proposed. Among them, second generation biofuel is one of the most promising technologies. Gasification based thermo-chemical conversion can utilize a wide range of biomass wastes and residues and bring flexibility to both feedstock and production sides of a plan. Thus it presents an attractive technical route. In this paper, a flexible feedstock thermo-chemical ethanol production process is investigated. This research focuses mainly on the evaluation of the feasibility of the process through numerical simulation. An existing thermo-chemical ethanol production model developed by NREL has been updated to handle the cases when different biomass feedstock and feedstock combinations are used. It is found that the ethanol yield is positively linear proportional to the feedstock feeding rate, while the total conversion efficiency is negatively proportional to the feeding rate. To demonstrate a feedstock management strategy, a plant located near a major city with a population of 200,000 and above is considered and MSW, corn stover and wood chips are selected as potential feedstock. Simulation results indicate that with wood chips as the backup feedstock the plant can be operated under extreme conditions when corn stover availability is significantly reduced without major equipment modification.

Review question / Objective: Currently, pars plana vitrectomy (PPV) with ILM peeling is the gold standard treatment for full thickness macular hole (FTMH). Despite of the high macular hole closure rate, a refractory FTMH may occur. The next step for a recurrent or persistent MH is usually repeat PPV with extended ILM peeling. This is not always an option especially with high myopia patients or those who had already undergone an aggressive ILM peeling at initial surgery. A variety of novel techniques have been developed to address this issue, among which human amniotic membrane seems to be a promising adjuvant. However, there are still uncertainties regarding the integration and the long-term effects of of the graft.

Full textAbstract:
Hybrid vigor is the leading concept that rules crops breeding for almost a century. Yet, the exact mechanism that underlies heterosis is not clear. Over dominance interaction between alleles is one of the possible explanations. Our preliminary results indicated that severe developmental mutations at the heterozygous state have significant potential to improve plant performance. This led us to propose the ‘ODO breeding method’ that is based replacing a parental line of a successful hybrid with its mutated from to improve hybrid performance. Our BARD research challenged this method in three crop systems: maize, tomato and melon. In maize we could not detect any effect of mutant heterozigosity on yield or yield components when hybrids were tested however when we analyzed the effect of heterozigosity in mutant genes at B73 genetic background we could detect ODO in yield components using certain mutants. Our results indicate that the potential of utilizing the ODO Breeding Method for maize remains unclear. In tomato we overcame technical problems we faced in creating an EMS mutation library in indeterminate glasshouse tomatoes and now we have in our hands advanced material to study the putative ODO hybrids. We transferred some of the promising ODO mutations from M82 to indeterminate glasshouse tomatoes and putative ODO hybrids are ready to be evaluated this winter. In addition, we tested the effect of In melon we compared putative ‘ODO hybrids’ with their isogenic hybrids lacking the mutant allele and our results indicated a potential for the ODO breeding method to improve yield, fruit number per plant, and carotenoids content. Additional experiments are required to estimate better the expected success percentage of the ODO breeding method in melon so that it will become a recommended practice for improving hybrid performance. Based on our results we can't yet recommend the 'ODO breeding method' as a general tool to improve hybrid performance and more efforts are necessary to evaluate the percent of success of this method. The increased carotenoid content we found in association with CRTISO heterozygosity is promising and additional experiments are currently being performed to characterize this finding.

Full textAbstract:
Original objectives The general goal of the project was to utilize the bactericidal potential of curcumin- functionalizednanostructures (CFN) for reinforcement of food safety by developing active antimicrobial food-contact surfaces. In order to reach the goal, the following secondary tasks were pursued: (a) further enhancement of the CFN activity based on understanding their mode of action; (b) preparing efficient antimicrobial surfaces, investigating and optimizing their performance; (c) testing the efficacy of the antimicrobial surfaces in real food trials. Background to the topic The project dealt with reducing microbial food spoilage and safety hazards. Cross-contamination through food-contact surfaces is one of the major safety concerns, aggravated by bacterial biofilm formation. The project implemented nanotech methods to develop novel antimicrobial food-contact materials based on natural compounds. Food-grade phenylpropanoidcurcumin was chosen as the most promising active principle for this research. Major conclusions, solutions, achievements In agreement with the original plan, the following research tasks were performed. Optimization of particles structure and composition. Three types of curcumin-functionalizednanostructures were developed and tested: liposome-type polydiacetylenenanovesicles, surface- stabilized nanoparticles and methyl-β-cyclodextrin inclusion complexes (MBCD). The three types had similar minimal inhibitory concentration but different mode of action. Nanovesicles and inclusion complexes were bactericidal while the nanoparticlesbacteriostatic. The difference might be due to different paths of curcumin penetration into bacterial cell. Enhancing the antimicrobial efficacy of CFN by photosensitization. Light exposure strengthened the bactericidal efficacy of curcumin-MBCD inclusion complexes approximately three-fold and enhanced the bacterial death on curcumin-coated plastic surfaces. Investigating the mode of action of CFN. Toxicoproteomic study revealed oxidative stress in curcumin-treated cells of E. coli. In the dark, this effect was alleviated by cellular adaptive responses. Under light, the enhanced ROS burst overrode the cellular adaptive mechanisms, disrupted the iron metabolism and synthesis of Fe-S clusters, eventually leading to cell death. Developing industrially-feasible methods of binding CFN to food-contact surfaces. CFN binding methods were developed for various substrates: covalent binding (binding nanovesicles to glass, plastic and metal), sonochemical impregnation (binding nanoparticles to plastics) and electrostatic layer-by-layer coating (binding inclusion complexes to glass and plastics). Investigating the performance of CFN-coated surfaces. Flexible and rigid plastic materials and glass coated with CFN demonstrated bactericidal activity towards Gram-negative (E. coli) and Gram-positive (Bac. cereus) bacteria. In addition, CFN-impregnated plastic material inhibited bacterial attachment and biofilm development. Testing the efficacy of CFN in food preservation trials. Efficient cold pasteurization of tender coconut water inoculated with E. coli and Listeriamonocytogeneswas performed by circulation through a column filled with CFN-coated glass beads. Combination of curcumin coating with blue light prevented bacterial cross contamination of fresh-cut melons through plastic surfaces contaminated with E. coli or Bac. licheniformis. Furthermore, coating of strawberries with CFN reduced fruit spoilage during simulated transportation extending the shelf life by 2-3 days. Implications, both scientific and agricultural BARD Report - Project4680 Page 2 of 17 Antimicrobial food-contact nanomaterials based on natural active principles will preserve food quality and ensure safety. Understanding mode of antimicrobial action of curcumin will allow enhancing its dark efficacy, e.g. by targeting the microbial cellular adaptation mechanisms.

Full textAbstract:
Ethylene is a plant hormone that controls many plant responses, such as growth, senescence, ripening, abscission and seed germination. Recently, 1-methy- cyclopropene (1-MCP), was shown to bind to ethylene receptor for a certain period of time and prevent ethylene action. The objectives of this research were to synthesize analogues of 1-MCP and test their potency to block the ethylene receptor and inhibit ethylene action. During the course of this project, procedures for synthesis and shipment of the cyclopropene compounds were developed as well assay procedures for each compound were worked out. Thirteen new compounds were synthesized. All of them are structural analogues of 1-MCP, with substitution in the 1-position and a side chain containing 2 to 10 carbons. After preliminary studies, nine promising compounds were selected for in-depth study. The potency of the compounds to inhibit ethylene action was tested on a wide scope of systems like: climacteric fruits (banana, avocado and tomato), the triple response (etiolated peas), and leaf abscission (citrus). As the putative inhibitors are suspected to compete for the site of binding and a competitive type of inhibition could be considered, a high concentration of ethylene (300 m1.L-1) was used to induce ripening and other physiological processes. The tests were conducted under extreme conditions which hasten ripening like treatment and storage at 22 to 25oC. There were fluctuations in the responses as related to the concentrations of the inhibitors. Some required much higher concentration to exert the same effect, while some, when applied at the same concentration, blocked the receptor for a longer period of time than the others. Some fruits and other plant organs responded differently to the same inhibitor, indicating differences in characteristics and availability of the ethylene receptors in the various tissues. The potency of the putative inhibitors was found to be greatly affected by their molecular structural and size. In addition, it was found that treatment with the inhibitor should be given before the onset of ethylene action In the case of fruit, treatment should be carried out before the pre-climacteric stage. Simultaneous treatment with ethylene and the inhibitors reduced the inhibitors' effect. The relationship between ethylene and the inhibitors is of a non-competitive nature. All the fruits treated with the putative inhibitors resumed normal ripening after recovery from the inhibition. This fact is of great importance when considering the inhibitors for practical use. The advantage of using inhibitors of ethylene action over inhibitors of ethylene production lies in the ability of the inhibitors of ethylene action to protect the tissue against both endogenous and exogenous ethylene, thus providing better overall protection. Our findings indicate that 1-MCP and its structural analogues are potent inhibitors of ethylene action capable of providing good protection against endogenous and exogenous ethylene. The fact that the compounds are in a gas phase and are non-phytotoxic, odorless and effective at minute concentrations, renders them promising candidates for commercial use. However, the development of water-soluble inhibitors will expand the potential use of the inhibitors in agriculture.

Full textAbstract:
California’s Local Control Funding Formula (LCFF), signed into law in 2013, centers equity as a key to increased and improved services for three targeted student subgroups, including English Learners (ELs), low-income students, and foster youth. As a component of LCFF, districts develop Local Control and Accountability Plans (LCAPs) to specify their goals and strategies for using LCFF funds for equity and continuous improvement purposes. The California Model Five by Five Grid Placement Report (Spring 2017 Dashboard) included the Five by Five Placement Grid, a key function of which is to identify the needs of diverse ELs. The Dashboard and the LCAPs are two policy mechanisms with great promise in combining school finance and accountability reform to promote equity and coherent state-wide. In this report, Lavadenz and colleagues review the EL policy context and examine the connection between the two contemporary policy mechanisms in California, namely the Year 4 LCAP and the California Department of Education’s Accountability Model (Spring 2017 Dashboard). The authors use a sample of 26 California school districts with high numbers/percentages of ELs and conclude that California’s current accountability system diminishes the urgency to respond to educational needs of the English Learner subgroup and undermines the equity intent of the LCFF. Few promising practices and assets-based approaches were identified in the LCAPs, and there is minimal mention of metrics focused on EL outcomes. The authors provide recommendations at state, county office of education and district levels.

Full textAbstract:
Polyphenol oxidases (PPOs) participate in the preparation of many plant products on the one hand and cause considerable losses during processing of plant products on the other hand. However, the physiological functions of plant PPO were still a subject of controversy at the onset of the project. Preliminary observations that suggested involvement of PPOs in resistance to herbivores and pathogens held great promise for application in agriculture but required elucidation of PPO's function if modulation of PPO expression is to be considered for improving plant protection or storage and processing of plant products. Suggestions on a possible role of PPO in various aspects of chloroplast metabolism were also relevant in this context. The characterization of plant PPO genes opened a way for achieving these goals. We reasoned that "understanding PPO targeting and routing, designing ways to manipulate its expression and assessing the effects of such modifications will enable determination of the true properties of the enzyme and open the way for controlling its activity". The objective of the project was to "obtain an insight into the function and biological significance of PPOs" by examining possible function(s) of PPO in photosynthesis and plant-pest interactions using transgenic tomato plants; extending our understanding of PPO routing and assembly and the mechanism of its thylakoid translocation; preparing recombinant PPOs for use in import studies, determination of the genuine properties of PPOs and understanding its assembly and determining the effect of PPO's absence on chloroplast performance. Results obtained during work on the project made it necessary to abandon some minor objectives and devote the effort to more promising topics. Such changes are mentioned in the 'Body of the report' which is arranged according to the objectives of the original proposal. The complex expression pattern of tomato PPO gene family was determined. Individual members of the family are differentially expressed in various parts of the plant and subjected to developmentally regulated turnover. Some members are differentially regulated also by pathogens, wounding and chemical wound signals. Wounding systemically induces PPO activity and level in potato. Only tissues that are developmentally competent to express PPO are capable of responding to the systemic wounding signal by increased accumulation of PPO mRNA. Down regulation of PPO genes causes hyper susceptibility to leaf pathogens in tomato while over expression regulation of PPO expression in tomato plants is their apparent increased tolerance to drought. Both the enhanced disease resistance conferred by PPO over expression and the increased stress tolerance due to down regulation can be used in the engineering of improved crop plants. Photosynthesis rate and variable fluorescence measurements in wild type, and PPO-null and over expressing transgenic tomato lines suggest that PPO does not enable plants to cope better with stressful high light intensities or reactive oxygen species. Rather high levels of the enzyme aggravate the damage caused under such conditions. Our work suggests that PPO's primary role is in defending plants against pathogens and herbivores. Jasmonate and ethylene, and apparently also salicylate, signals involved in responses to wounding and defense against herbivores and pathogens, enhance markedly and specifically the competence of chloroplasts to import and process pPPO. The interaction of the precursor with thylakoid membranes is primarily affected. The routing of PPO shows other unusual properties: stromal processing occurs in two sites, resulting in intermediates that are translocated across thylakoids by two different mechanisms - a DpH- and a Sec-dependent one. It is suggested that the dual pattern of processing and routing constitutes a'fail safe' mechanism, reflecting the need for a rapid and flexible response to defense challenges. Many of the observations described above should be taken into consideration when manipulation of PPO expression is contemplated for use in crop improvement.

In conducting this research, we explored all combinations of tetraploid and diploid parents, in reciprocal combinations. Pollinations were made in both the field and greenhouse, using emasculated flowers, moneocious females, and open pollination by insect vectors, with morphological selection criteria. After observations of thousands of ovaries, we still have no definitive proof that this hybridization yielded viable embryos. The most promising results came from using tetraploid C. metuliferus, as the maternal parent in the interspecific hybridization, that set fruit were seeds contained small embryos that did not germinate. To obtain fruit set, it was important to rear plants in a cooler sunny greenhouse, as would be found in late winter/early spring. A second interspecific hybrid between wild and cultivated Cucumis, C. hystrix x C. sativus, yielded fertile progeny for the first time, while concomitantly working toward our primary goal. Two distinct treatments were necessary; 1) special plant husbandry was necessary to have the wild species produce fruit in cultivation, and 2) embryo rescue followed by chromosome doubling in vitro was required for fertility restoration. Backcrosses to crop species and resistance to nematodes are compelling areas for further work.

Full textAbstract:
Control of agro-associated pathogens is becoming increasingly difficult due to increased resistance and mounting restrictions on chemical pesticides and antibiotics. Likewise, in veterinary and human environments, there is increasing resistance of pathogens to currently available antibiotics requiring discovery of novel antibiotic compounds. These drawbacks necessitate discovery and application of microorganisms that can be used as biocontrol agents (BCAs) and the isolation of novel biologically-active compounds. This highly-synergistic one year project implemented an innovative pipeline aimed at detecting BCAs and associated biologically-active compounds, which included: (A) isolation of multidrug-resistant desert soil bacteria and root-associated bacteria from medicinal plants; (B) invitro screening of bacterial isolates against known plant, animal and human pathogens; (C) nextgeneration sequencing of isolates that displayed antagonistic activity against at least one of the model pathogens and (D) in-planta screening of promising BCAs in a model bean-Sclerotiumrolfsii system. The BCA genome data were examined for presence of: i) secondary metabolite encoding genes potentially linked to the anti-pathogenic activity of the isolates; and ii) rhizosphere competence-associated genes, associated with the capacity of microorganisms to successfully inhabit plant roots, and a prerequisite for the success of a soil amended BCA. Altogether, 56 phylogenetically-diverse isolates with bioactivity against bacterial, oomycete and fungal plant pathogens were identified. These strains were sent to Auburn University where bioassays against a panel of animal and human pathogens (including multi-drug resistant pathogenic strains such as A. baumannii 3806) were conducted. Nineteen isolates that showed substantial antagonistic activity against at least one of the screened pathogens were sequenced, assembled and subjected to bioinformatics analyses aimed at identifying secondary metabolite-encoding and rhizosphere competence-associated genes. The genome size of the bacteria ranged from 3.77 to 9.85 Mbp. All of the genomes were characterized by a plethora of secondary metabolite encoding genes including non-ribosomal peptide synthase, polyketidesynthases, lantipeptides, bacteriocins, terpenes and siderophores. While some of these genes were highly similar to documented genes, many were unique and therefore may encode for novel antagonistic compounds. Comparative genomic analysis of root-associated isolates with similar strains not isolated from root environments revealed genes encoding for several rhizospherecompetence- associated traits including urea utilization, chitin degradation, plant cell polymerdegradation, biofilm formation, mechanisms for iron, phosphorus and sulfur acquisition and antibiotic resistance. Our labs are currently writing a continuation of this feasibility study that proposes a unique pipeline for the detection of BCAs and biopesticides that can be used against phytopathogens. It will combine i) metabolomic screening of strains from our collection that contain unique secondary metabolite-encoding genes, in order to isolate novel antimicrobial compounds; ii) model plant-based experiments to assess the antagonistic capacities of selected BCAs toward selected phytopathogens; and iii) an innovative next-generation-sequencing based method to monitor the relative abundance and distribution of selected BCAs in field experiments in order to assess their persistence in natural agro-environments. We believe that this integrated approach will enable development of novel strains and compounds that can be used in large-scale operations.
