Developement of real time diagnostics and feedback algorithms for JET in view of the next step

Real time control of many plasma parameters will be an essential aspect in the development of reliable high performance operation of Next Step Tokamaks. The main prerequisites for any feedback scheme are the precise real-time determination of the quantities to be controlled, requiring top quality and highly reliable diagnostics, and the availability of robust control algorithms. A new set of real time diagnostics was recently implemented on JET to prove the feasibility of determining, with high accuracy and time resolution, the most important plasma quantities. With regard to feedback algorithms, new model–based controllers were developed to allow a more robust control of several plasma parameters. Both diagnostics and algorithms were successfully used in several experiments, ranging from H-mode plasmas to configuration with ITBs. Since elaboration of computationally heavy measurements is often required, significant attention was devoted to non-algorithmic methods like Digital or Cellular Neural/Nonlinear Networks. The real time hardware and software adopted architectures are also described with particular attention to their relevance to ITER.Comment: 12th International Congress on Plasma Physics, 25-29 October 2004, Nice (France

Applications of lignin in the agri-food industry

Of late, valorization of agri-food industrial by-products and their sustainable utilization is gaining much contemplation world-over. Globally, 'Zero Waste Concept' is promoted with main emphasis laid towards generation of minimal wastes and maximal utilization of plantbased agri-food raw materials. One of the wastes/by-products in the agri-food industry are the lignin, which occurs as lignocellulosic biomass. This biomass is deliberated to be an environmental pollutant as they offer resistance to natural biodegradation. Safe disposal of this biomass is often considered a major challenge, especially in low-income countries. Hence, the application of modern technologies to effectively reduce these types of wastes and maximize their potential use/applications is vital in the present day scenario. Nevertheless, in some of the high-income countries, attempts have been made to efficiently utilize lignin as a source of fuel, as a raw material in the paper industry, as a filler material in biopolymer based packaging and for producing bioethanol. However, as of today, agri-food industrial applications remains significantly underexplored. Chemically, lignin is heterogeneous, bio-polymeric, polyphenolic compound, which is present naturally in plants, providing mechanical strength and rigidity. Reports are available wherein purified lignin is established to possess therapeutic values; and are rich in antioxidant, anti-microbial, anti-carcinogenic, antidiabetic properties, etc. This chapter is divided into four sub-categories focusing on various technological aspects related to isolation and characterization of lignin; established uses of lignin; proved bioactivities and therapeutic potentials of lignin, and finally on identifying the existing research gaps followed by future recommendations for potential use from agri-food industrial wastes.Theme of this chapter is based on our ongoing project- Valortech, which has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 810630

A systematic review on the excess health risk of antibiotic-resistant bloodstream infections for six key pathogens in Europe

Background: Antimicrobial resistance is a global threat, which requires novel intervention strategies, for which priority pathogens and settings need to be determined. Objectives: We evaluated pathogen-specific excess health burden of drug-resistant bloodstream infections (BSIs) in Europe. Methods: A systematic review and meta-analysis. Data sources: MEDLINE, Embase, and grey literature for the period January 1990 to May 2022. Study eligibility criteria: Studies that reported burden data for six key drug-resistant pathogens: carbapenem-resistant (CR) Pseudomonas aeruginosa and Acinetobacter baumannii, third-generation cephalosporin or CR Escherichia coli and Klebsiella pneumoniae, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecium. Excess health outcomes compared with drug-susceptible BSIs or uninfected patients. For MRSA and third-generation cephalosporin E. coli and K. pneumoniae BSIs, five or more European studies were identified. For all others, the search was extended to high-income countries. Participants: Paediatric and adult patients diagnosed with drug-resistant BSI. Interventions: Not applicable. Assessment of risk of bias: An adapted version of the Joanna-Briggs Institute assessment tool. Methods of data synthesis: Random-effect models were used to pool pathogen-specific burden estimates. Results: We screened 7154 titles, 1078 full-texts and found 56 studies on BSIs. Most studies compared outcomes of drug-resistant to drug-susceptible BSIs (46/56, 82.1%), and reported mortality (55/56 studies, 98.6%). The pooled crude estimate for excess all-cause mortality of drug-resistant versus drug-susceptible BSIs ranged from OR 1.31 (95% CI 1.03–1.68) for CR P. aeruginosa to OR 3.44 (95% CI 1.62–7.32) for CR K. pneumoniae. Pooled crude estimates comparing mortality to uninfected patients were available for vancomycin-resistant Enterococcus and MRSA BSIs (OR of 11.19 [95% CI 6.92–18.09] and OR 6.18 [95% CI 2.10–18.17], respectively). Conclusions: Drug-resistant BSIs are associated with increased mortality, with the magnitude of the effect influenced by pathogen type and comparator. Future research should address crucial knowledge gaps in pathogen- and infection-specific burdens to guide development of novel interventions

Utilização da polpa de batata residual em snacks como perspectiva de redução do impacto ambiental

Neste trabalho se propôs caracterizar a polpa residual de lavagem de batatas desidratadas (PRLBD) e sua utilização em snacks fritos, visando à reutilização de resíduos gerados pelas agroindústrias. Amostras da água de lavagem de quatro cultivares de batata (Atlantic, Markies, Inovaiter e Asterix) foram coletadas e em seguida secadas. As características físicas e químicas das quatro PRLBD indicam que todas podem ser utilizadas como ingrediente na formulação de produtos alimentícios. Os snacks foram formulados com substituição parcial da farinha de trigo pela PRLBD (0, 10, 20 e 50%). Os resultados das análises microbiológicas realizadas com a PRLBD cultivar Atlantic, assim como os snacks, atendem aos requisitos da legislação brasileira não apresentando risco proeminente para a saúde humana (ausência de Salmonella; Coliformes a 45 °C < 100 UFC g-1 e Bacillus cereus < 3000 UFC g-1). As análises sensoriais mostraram que os snacks formulados foram os preferidos pelo consumidor, além de possuir um teor de lipídios 24% menor. Conclui-se que este novo processo de fabricação de snacks contribuirá para a sustentabilidade agroindustrial reduzindo os impactos ambientais gerados pelo processamento de batatas fritas, além de ser um produto mais saudável para o consumidor
