Bi-level stochastic energy trading model for technical virtual power plants con...

he ongoing transition of the energy system towards being low-carbon, digitized and distributed is accelerating. Distributed Energy Resources (DERs) are playing a major role in this transition. These DERs can be aggregated and controlled by Virtual Power Plants (VPPs) to participate in energy markets and make full use of the potential of DERs. Many existing VPP models solely focus on the financial impact of aggr...

Expressão imunoistoquímica e molecular da laminina-332 cadeia gama-2 em tumores...

Made available in DSpace on 2022-04-28T18:56:45Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-02-01; Forty-eight cases of canine mammary cancer were investigated to evaluate the immunohistochemical distribution of the γ2 chain of laminin-332. Tumor cells were compared to a pool of normal mammary tissues using quantitative RT-PCR. The western blot was performed in eight tumor samples as complementary te...

Optimal scheduling of commercial demand response by technical virtual power plants

The trend towards a decentralized, decarbonized, and digital energy system is gaining momentum. A key driver of this change is the rapid penetration increase of Distributed Energy Resources (DER). Commercial consumers can offer significant contributions to future energy systems, especially by engaging in demand response services. Virtual Power Plants (VPP) can aggregate and operate DERs to provide the required ...

Mechanical pruning in non-irrigated vineyards: effects on yield and grape compo...

The effect of mechanical pruning on vine performance and wine quality was evaluated from 2012 until 2015. Two trial fields, with a randomized complete block design, were established on already existing ‘Syrah’ vineyards in Quinta do Côro and Quinta do Gradil, located in Tejo and Lisboa wine regions respectively. Mechanical pruning (MEC) was simulated by trimming all shoots to a 15 cm square around the cordon. M...

Organic amendments application to soil of mechanically pruned vineyards: effect...

The effect of three different soil organic amendments on vine performance and wine quality of mechanically box pruned vineyards was evaluated from 2012 until 2015. Two field trials, with a randomized complete block design, were established on ‘Syrah’ vineyards at Quinta do Côro (QC) and Quinta do Gradil (QG), Tejo and Lisboa wine regions respectively. Organic amendments – municipal solid waste compost (MSWC) an...

Prevalence of gonorrhea and chlamydia in a community clinic for men who have se...

Men who have sex with men (MSM) are at greater risk for sexually transmitted infections (STIs). Data on MSM chlamydia and gonorrhea prevalence estimates and associated risk factors are scarce. To our knowledge, this is the first study to describe the prevalence and the determinants of both chlamydia and gonorrhea infections in MSM in Portugal. We conducted a cross-sectional study using data from 1832 visits to ...

Enhancement of methane production from 1-hexadecene by additional electron donors

1-Hexadecene-contaminated wastewater is produced in oil refineries and can be treated in methanogenic bioreactors, although generally at low conversion rates. In this study, a microbial culture able to degrade 1-hexadecene was enriched, and different stimulation strategies were tested for enhancing 1-hexadecene conversion to methane. Seven and three times faster methane production was obtained in cultures stimu...

Estimation of the collective ionizing dose in the Portuguese population for the...

Objectives: In 2009-2010 a Portuguese consortium was created to implement the methodologies proposed by the Dose Datamed II (DDM2) project, aiming to collect data from diagnostic X-ray and nuclear medicine (NM) procedures, in order to determine the most frequently prescribed exams and the associated ionizing radiation doses for the Portuguese population. The current study is the continuation of this work, altho...
