Assessment of the production costs curve in micro-grids: a comparative analysis

2012

In micro-grids, due to their small scale, there is commonly only one power supplier. A competitive wholesale market hardly exists so the question about how to consider market issues for small producers within micro-grids arises. On the other hand, the specific features of micro-grids where load and generated power hardly find a balance, require that customers take part to regulation issues, maybe using demand response programs. In this paper, price responsive policies and its programs are discussed to answer this question. A case study of a micro-grid with one microturbine and two photovoltaic generators in Italy is analyzed to assess the overall production cost in order to build a price re…

Microwave response of bulk MgB2 samples of different granularity

2006

The microwave response of three high-density bulk MgB2 samples has been investigated in the linear and nonlinear regimes. The three samples, characterized by different mean size of grains, have been obtained by reactive infiltration of liquid Mg in powdered B preforms. The linear response has been studied by measuring the microwave surface impedance; the nonlinear response by detecting the power radiated by the sample at the second-harmonic frequency of the driving field. Our results suggest that bulk MgB2 prepared by the liquid Mg infiltration technique is particularly promising for manufacturing resonant cavities operating at microwave frequencies.

Mobile money as a driver of digital financial inclusion

2023

Meeting the mobile money needs of the less privileged in developing and emerging markets opens up enormous possibilities for banks and newly emerged financial-technology firms. Many consider mobile money services a separate domain within the banking and payment sector, different from its siblings: automated teller machines, net banking, point-of-sale banking, etc. This study was conducted to investigate how mobile money services act as a reliable driver of digital financial inclusion and to determine the role of mobile money agents in the transformation from the traditional services to mobile money services. This paper presents a conceptual model based on the stimulus-organism-response para…

Paving the way of systems biology and precision medicine in allergic diseases: The MeDALL success story

2016

MeDALL Mechanisms of the Development of ALLergy; EU FP7-CP-IP; Project No: 261357; 20 (10) -2015 proposed an innovative approach to develop early indicators for the prediction, diagnosis, prevention and targets for therapy(.) MeDALL linked epidemiological, clinical and basic research using a stepwise, large-scale and integrative approach: precisely phenotyped children followed in 14 birth cohorts spread across Europe were combined with systems biology omics, IgE measurement using micro-arrays and environmental data(.) Multimorbidity in the same child is more common than expected by chance alone, suggesting that these diseases share causal mechanisms irrespective of IgE sensitisation(.) IgE …

How to define deviance residuals in multinomial regression.

2015

This work is devoted to the study of diagnostic tools for categorical data models with an emphasis on the presence of continuous covariates. In particular, the aim is to define a new class of residuals from the parametric multinomial family of models and to study their asymptotics properties. In logistic regression (as in generalized linear models), there are a few different kinds of residuals; we propose a generalization of deviance residuals as defined in logistic regression to the multinomial case and propose their use in order to identify inadequacies in a multinomial model.

The soluble terminal complement complex (SC5b-9) up-regulates osteoprotegerin expression and release by endothelial cells: Implications in rheumatoid…

2009

Objective. Complement activation products contribute to a large number of inflammatory diseases, including RA. We have investigated whether osteoprotegerin (OPG) may concur with the soluble terminal complement complex (SC5b-9) to the inflammatory cascade characterizing RA. Methods. Levels of SC5b-9 and OPG in the plasma and SF of patients with active RA were determined by ELISA. The presence of SC5b-9 and OPG in RA synovial lesions was analysed by immunohistochemistry. Cultured endothelial cells were used for in vitro leucocyte/endothelial cell adhesion assays. In addition, endothelial cells were exposed to SC5b-9 in order to evaluate the effects on the production of OPG protein, as well as…

Duodenal contractile activity in dystrophic (mdx) mice: reduction of nitric oxide influence.

2003

The present study was undertaken to analyse duodenal contractility in adult dystrophic (mdx) mice. The spontaneous changes of the isometric tension and the responses of longitudinal duodenal muscle to nonadrenergic, noncholinergic (NANC) nerve stimulation and to exogenous drugs were compared between normal and mdx mice. Duodenal segments from mdx mice displayed spontaneous contractions with higher frequency than normals. N omega-nitro-L-arginine methyl ester (L-NAME) increased the frequency of contractions in normals without affecting that in mdx mice. In normals, NANC nerve stimulation elicited a transient relaxation abolished by L-NAME. In mdx mice a frank relaxation was not observed, the…

IAPs: more than just inhibitors of apoptosis proteins.

2008

Inhibitors of apoptosis proteins (IAPs) are a conserved family of proteins identified in species ranging from virus, yeasts, nematodes, fishes, flies and mammals. The common structural feature is the presence of at least one Baculovirus IAP Repeat (BIR) domain. Hence, IAPs are also known as BIR-containing proteins (BIRCs). Most of them display anti-apoptotic properties when overexpressed. In drosophila, IAPs are sufficient and necessary to promote cell survival through a direct regulation of apoptotic proteases called caspases. In mammals, BIRC4/XIAP, the most studied IAP member can directly inhibit the activity of caspase-3, 7 and 9. However, this activity is not conserved in other IAPs an…

Treatment with a CO-releasing molecule (CORM-3) reduces joint inflammation and erosion in murine collagen-induced arthritis.

2008

Contains fulltext : 70589.pdf (Publisher’s version ) (Closed access) OBJECTIVE: CO-releasing molecules (CO-RMs) are a novel class of anti-inflammatory agents. We have examined the possible therapeutic effects of CORM-3 in collagen-induced arthritis (CIA). METHODS: Arthritis was induced in DBA-1/J mice by type II collagen. Animals were treated with CORM-3 (5 and 10 mg/kg/day, intraperitoneally) or the inactive compound iCORM-3 (10 mg/kg/day, intraperitoneally) unable to release CO, from days 22 to 31. Production of anti-type II collagen antibodies, cytokines and cartilage olimeric matrix protein (COMP) was evaluated by enzyme-linked immunosorbent assay, and prostaglandin E(2) (PGE(2)) by rad…
