Energy and environmental impact of an anaerobic membrane bioreactor (AnMBR) demonstration plant treating urban wastewater
2020
Abstract In order to assess the environmental feasibility of anaerobic membrane bioreactor (AnMBR) technology for urban wastewater (UWW) treatment at ambient temperature, a demonstration plant was operated within the LIFE MEMORY project ( http://www.life-memory.eu/en/ ). This plant incorporates full-scale hollow-fiber membrane modules and was fed with the effluent from the pre-treatment of the “Alcazar de San Juan” WWTP (Alcazar de San Juan, Ciudad Real, Spain). Because of the dimensions of this plant, the system can be regarded as a previous step to the scale-up of AnMBR technology for full-scale UWW treatment. High-energy recovery potentials were achieved treating medium-/high-loaded UWW …
Eradication of Culex pipiens fatigans through Cytoplasmic Incompatibility
1967
Culex pipiens fatigans is the chief vector of filariasis in south-east Asia. Urbanization has often caused the numbers of this mosquito—and with it the danger of filariasis infection—to increase alarmingly1. The natural vigour, tolerance and fast development of resistance to insecticides of this mosquito necessitate the development of other control methods, and cytoplasmic incompatibility2 seems to be an ideal means.
Veterinary drug residues in meat: Concerns and rapid methods for detection.
2007
The use of substances having hormonal or thyreostatic action as well as β-agonists is banned in the European Union. However, sometimes forbidden drugs may be added to feeds for illegal administration to farm animals for promoting increased muscle development or increased water retention and thus obtain an economical benefit. The result is a fraudulent overweight of meat but, what is worse, residues of these substances may remain in meat and may pose a real threat to the consumer either through exposure to the residues, transfer of antibiotic resistance or allergy risk. This has exerted a great concern among European consumers. The control of the absence of these forbidden substances in anim…
Landing gear suspension control through adaptive backstepping techniques with H∞ performance
2011
Author's version of a chapter published in the book: Proceedings of the 18th IFAC World Congress 2011. Also available from the publisher at: http://dx.doi.org/10.3182/20110828-6-IT-1002.00589 Landing gear suspension systems fulfill the tasks of absorbing the vertical energy of the touch-down as well as providing passenger and crew comfort with a smooth ground ride before take-off and after landing. They are also designed to have optimal performance in the case of a hard landing. In general, the tasks of aircraft landing gears are complex and sometimes lead to a number of contradictory requirements. Although there are existing modifications of aircraft shock absorbers to reduce the problem, …
National economy: Quality Research of Products and Goods
1993
This edition is to reflect research results with modern analytical methodology including measurements and examinations with spectrophotometric appliances in combination with modern nondestructive testing methods which are employed in farming products' analysis and in merchandise quality control as well as relative advantages in terms of methodology.
Comparison of well-being of older adult choir singers and the general population in Finland: A case-control study
2016
Previous research suggests that singing in a choir as an older adult is associated with better quality of life (QOL). However, the degree to which sociodemographic variables and level of engagement in hobbies contribute to this relationship is largely unknown. The aim of the study was to compare quality of life (QOL) of older adult choir singers with a matched sample of older adults from the general population in Finland, taking into consideration sociodemographic variables, satisfaction with health, and level of engagement in hobbies. Case-control methods were used to match a sample of 109 older adult singers with a sample of 307 older adults from the general population. Tobit regression …
Control of freshwater fish louse Argulus coregoni: a step towards an integrated management strategy
2008
Harmful infections by ectoparasites of the genus Argulus occur repeatedly in freshwa- ter fish farming operations where the management has largely been ineffective. Preventative meth- ods and regular monitoring are rarely applied, so that chemical interventions become necessary. According to the Integrated Pest Management (IPM) approach, a sustainable management or control program for a parasite should be based on knowledge of the ecology of the parasite along with adop- tion of several prevention and control methods, the application of which is dependent upon the pre- vailing infection level. The application of multiple management tactics is especially important because parasites can devel…

Mycotoxins in dry-cured meats: A review
2017
Dry-cured meats products are consumed in various regions of the world and, consumers are increasingly demanding better quality and safety of these products. Some fungal species can produce mycotoxins in drycured meats, such as aflatoxins and ochratoxins, which, when ingested, can produce carcinogenic and mutagenic effects in humans. Contamination of these products can occur at different points of the production chain, from the field (animal contaminated with feed) to the production or storage of the final product. Although the presence of mycotoxins in drycured meats has been reported in several regions of the world, the presence of these contaminants are not legislated in most countries. T…
