Quantifying the demand-side response capability of industrial plants to participate in power system frequency control schemes

© 2015 IEEE.Efficiency and sustainability considerations have propelled changes in power and process industries. These changes, which include the increased electrification of process industries, are causing concerns about the reliability of future electricity supplies, and therefore motivate the need for a Smart Grid on an industrial scale. This paper presents a method by which process automation engineers can assess the suitability of an oil and gas plant to participate in power system frequency control services. This paper discusses the necessary specifications for an automated system that enables effective variable operation by analysing the safe operating envelope of the plant. To do that, this paper proposes a methodology to characterise the appropriate actuators, variables and limits of set-point change. This methodology is applied to a case study representing an oil processing facility. The resulting analysis indicates demandside response capability that the facility can provide without jeopardising operations on-site

The BlueBio project’s database: web-mapping cooperation to create value for the Blue Bioeconomy

Funding innovation requires knowledge on previous/on-going research and identification of gaps and synergies among actors, networks and projects, but targeted databases remain scattered, incomplete and scarcely searchable. Here we present the BlueBio database: a first comprehensive and robust compilation of internationally and nationally funded research projects active in the years 2003–2019 in Fisheries, Aquaculture, Seafood Processing and Marine Biotechnology. Based on the previous research projects’ database realized in the framework of the COFASP ERA-NET, it was implemented within the ERA-NET Cofund BlueBio project through a 4-years data collection including 4 surveys and a wide data retrieval. After being integrated, data were harmonised, shared as open and disseminated through a WebGIS that was key for data entry, update and validation. The database consists of 3,254 “georeferenced” projects, described by 22 parameters that are clustered into textual and spatial, some directly collected while others deduced. The database is a living archive to inform actors of the Blue Bioeconomy sector in a period of rapid transformations and research needs and is freely available at: https://doi.org/10.6084/m9.figshare.21507837.v3

Denaturing Gradient Gel Electrophoresis (DGGE) as a Powerful Novel Alternative for Differentiation of Epizootic ISA Virus Variants

Infectious Salmon Anemia is a devastating disease critically affecting world-wide salmon production. Chile has been particularly stricken by this disease which in all cases has been directly related with its causative agent, a novel orthomyxovirus which presents specific and distinctive infective features. Among these, two molecular markers have been directly associated with pathogenicity in two of the eight RNA sub genomic coding units of the virus: an insertion hot spot region present in viral segment 5 and a Highly Polymorphic Region (HPR) located in viral segment 6. Here we report the successful adaptation of a PCR-dependent denaturing gel electrophoresis technique (DGGE), which enables differentiation of selected reported HPR epizootic variants detected in Chile. At the same time, the technique allows us to distinguish one nucleotide differences in sequences associated with the intriguing, and still not well-understood, insertion events which tend to occur on RNA Segment 5. Thus, the versatility of the technique opens new opportunities for improved understanding of the complex biology of all ISA variants as well as possible applications to other highly variable pathogens

Skader på fisk ved Sørnes Smolt A.S. på Trengereid. (Fish injuries and mortalities at Sørnes Smolt A.S. fish hatchery, Trengereid, West Norway.)

Forlengelse av vannveien for Trengereid Kraftverk har pågått i Trengereidvassdragets nedslagsfelt vinteren 1995-96. Vassdraget er vannkilde for settefiskanlegget Sørnes Smolt A.S. I desember 1995 ble fiskebestanden i anlegget anslått til 216.000 stk. 0+ presmolt av laks. Mildvær i januar 1996 ga avrenning av surt smeltevann som dro med seg finparikulært materiale fra utsprengte tunnelmasser. Høy dødelighet i settefiskanlegget på samme tid settes i forbindelse med surt, metallholdig vann (aluminium, jern), silting og forhøyet CO2-innhold, det siste som følge av kjemisk reaksjon mellom partikler og vann. En slik sammensatt årsakssammenheng understøttes av registrerte skader på gjelle-og nyreorganene hos fisken. Gjelleforandringene svarer til det man kan finne hos fisk som utsettes for surt, aluminiumholdig vann, og nyreforandringene går klart i retning av nefrokalsinose. De skader som ble konstatert i prøvematerialet av fisk fra februar 1996 anses ikke som alvorlige nok til å forklare den massive og vedvarende fiskedøden i oppdrettsanlegget utover senvinteren og våren. I tillegg har langvarig nedsatt vanntilførsel, gjentatte episoder med avsmelting og silting, samt hyppig håndtering av fisken bidratt til stressing av en allerde svekket fiskebestand. Dødeligheten fra 9. januar til 9. april 1996 er estimert til 170.000 individer.Trengereid kraft A.
