    Analysing electricity flows and congestions: looking at locational patterns

    Countries are making important efforts decarbonising their electricity generation mix. In this context, improving the operational efficiency enables better use to be made by renewables and the grids. However, the location of new capacity might be relevant from the social welfare point of view when private decisions might affect the power system efficiency. In this paper, we analyze the Spanish transmission grid with the aim to explore in the power system efficiencies with a high share of renewables in the generation mix. We explore in the location of the generation technologies to see how efficient they are located with regard to the consumption. We find wind is one of the least efficiently located, which has implied relevant grid investments paid by consumers. Moreover, a high concentration of renewables increases grid-congestions, which might constrain locations for future capacity. Our results highlight there is a trade-off between incomes from RES and grid costs paid by consumers. Therefore, we suggest RES policies should include some locational incentives. We analyze pros and cons from some choices and conclude countries should provide further grid information to incumbents and also include locational incentives in future RES auctions. Indeed, results from this paper represent a first stage in the design of these locational incentives

    Shewanella algae infection in Italy: report of 3 years' evaluation along the coast of the northern Adriatic Sea

    Shewanella algae are Gram-negative, nonfermentative, motile bacilli, classified in the genus Shewanella in 1985. These environmental bacteria are occasionally identified in human infections, with a relatively strong association with exposure to seawater during warm seasons. This report describes a case series of 17 patients with infection correlated to S. algae in the coastal area of Romagna, Italy, from 2013 to 2016. The types of infection included otitis, pneumonia, sepsis and soft tissue (wound). Exposure to the marine environment during hot months was confirmed in 12 of 17 patients. An apparent correlation between increased severity of infection and patient age was also observed

    Percutaneous Venous Angioplasty in Patients With Multiple Sclerosis And Chronic Cerebrospinal Venous Insufficiency: A Randomized Wait List Control Study

    Objectives: Venous percutaneous transluminal angioplasty (vPTA) in patients with multiple sclerosis (MS) and chronic cerebrospinal venous insufficiency (CCSVI) have shown contradictory results. Aim of the study is to evaluate the efficacy of the procedure in a randomized wait list control study. Materials: 66 adults with neurologist-confirmed diagnosis of MS and sonographic diagnosis of CCSVI were allocated in to vPTA-yes group (n=31) or vPTA-not group (n=35, control group). Venous PTA was performed immediately 15 days after randomization in PTA-yes group and 6 months later in the control group. Methods: Evoked potentials (EPs), clinical-functional measures (CFM) and upper limb kinematic measures (ULKM) were measured at baseline (T0) and six months after in both groups, just before the venous angioplasty in vPTA-not group (T1). Results: Comparing vPTA-yes and vPTA-not group, the CFM derived composite functional outcome showed 11(37%) versus 7(20%) improved, 1(3%) versus 3(8%) stable, 0 versus 7(20%) worsened and 19(61%) versus 18(51%) mixed patients (\u3c72=8.71, df=3, p=0.03). Unadjusted and adjusted (for baseline confounding variables) OR at 95% confident interval (95%CI) were respectively 1.93(1.3-2.8) P-value 0.0007 and 1.85(1.2-1.7) P-value 0.002. EPs and ULKM derived composite functional outcome showed no significant difference between the two groups. Conclusions: Venous angioplasty can positively impact a few CFM especially for the quality of life, but achieving disability improvement is unlikel

    Relazione semantica e temporale tra gesti e parole in un compito di denominazione

    This study explores semantic and temporal relationship between spontaneous gestures and speech produced by 45 hearing children (age range 24-37 months) in a picture naming task. Five pictures depicting objects (and an animal) and five pictures depicting actions which elicited more representational gestures were chosen for these analysis. Gestures produced were analyzed distinguishing between ?action? gestures and ?size and shape? gestures. The relationship between gesture and speech was analyzed in terms of: temporal synchrony/asynchrony, including mutual placement, and semantic match/mismatch, by using ELAN (EUDICO Linguistic Annotator). Results show that gestures and speech mainly convey similar meanings and that gestural stroke was produced synchronically with speech in the majority of cases. Onset time appears to be influenced by the item: gestural production tends to be produced before the spoken word onset in front of pictures depicting actions, but after in front of pictures depicting objects/animal. The results seem to support the Information Packaging Hypothesis (Alibali et al., 2000) where gestures and speech appear as an integrated system

    Comparative evaluation of the novel bionexia legionella test with the BinaxNOW legionella card assay and the sofia legionella FIA assay for detection of legionella pneumophila (serogroup 1) antigen in urine samples

    A new immunochromatographic test (bioNexia Legionella; bioM\ue9rieux) for the detection of Legionella pneumophila urinary antigen was evaluated in 255 urine samples. The results were compared with those obtained by the BinaxNOW and Sofia Legionella tests. The novel test compared well with those currently in use

    Bacterial vaginosis: epidemiologic, clinical and diagnostic updates

    Background and aims. Bacterial vaginosis (BV) is one the more frequently identified genital syndrome among childbearing aged women. The basic condition that generates this condition is a modification in the vaginal microbiota. The aim of this paper is to briefly review the current status of the art of BV and to report the results of a pilot study performed with an innovative PCR based technique. vaginae has been identified in 20 samples by the molecular approach and Lactobacillus spp. was identified in 19 samples (by culture) and in 32 by PCR. The overall diagnosis of BV was made in 9 patients by standard techniques and in 7 by applying the molecular approach. (Cohen\u2019s kappa test: 0,84). The findings of this study clearly demonstrate that the joint use of the routine cul- ture-based techniques with the multiplex PCR methods amplifies by far the sensitivity of the overall diagnostic workflow of BV
