Behaviour in compression of lightweight fiber reinforced concrete confined with transverse steel reinforcement

2004

Abstract The compressive behavior of lightweight fiber reinforced concrete confined with transverse reinforcement consisting of steel stirrups or spirals was analyzed. Pumice stone and expanded clay aggregates were utilized to decrease the weight of the composite; hooked steel fibers were also added. The investigation was carried out by testing cylindrical and prismatic specimens of different sizes in compression using an open-loop displacement control machine, recording the full load–deformation curves. The influence of the dimensions and shape on the bearing capacity and on the ductility of the specimens confined with transverse steel reinforcements was analyzed. The results show the poss…

Multiple sclerosis severity score: Using disability and disease duration to rate disease severity

2005

Background: There is no consensus method for determining progression of disability in patients with multiple sclerosis (MS) when each patient has had only a single assessment in the course of the disease. Methods: Using data from two large longitudinal databases, the authors tested whether cross-sectional disability assessments are representative of disease severity as a whole. An algorithm, the Multiple Sclerosis Severity Score (MSSS), which relates scores on the Expanded Disability Status Scale (EDSS) to the distribution of disability in patients with comparable disease durations, was devised and then applied to a collection of 9,892 patients from 11 countries to create the Global MSSS. I…

Il Medium come Habitat. Tecnologia e sensibilità nell'esperienza artistica dell’Expanded Cinema e del Light & Space Movement.

L’intenzione alla base della mia proposta teorica, che ho definito appunto “il medium come habitat”, è quella di riattualizzare la questione della medialità in relazione ad un habitat che non deve essere esclusivamente inteso come ambiente naturale (quello dell’ecologia) o come ambiente sociale (dell’antropologia o della sociologia). L’habitat piuttosto è da considerarsi come un campo esperienziale attraversato e definito da relazioni in continuo divenire, radicate in primo luogo nel rapporto sensibile e affettivo, estetico che mette in comunicazione tra loro i vari elementi, e questi ultimi con l’habitat che essi popolano. Le strategie di organizzazione e attribuzione di senso alla realtà …

Ocrelizumab initiation in patients with MS

2020

ObjectiveTo provide first real-world experience on patients with MS treated with the B cell–depleting antibody ocrelizumab.MethodsWe retrospectively collected data of patients who had received at least 1 treatment cycle (2 infusions) of ocrelizumab at 3 large neurology centers. Patients' characteristics including premedication, clinical disease course, and documented side effects were analyzed.ResultsWe could identify 210 patients (125 women, mean age ± SD, 42.1 ± 11.4 years) who had received ocrelizumab with a mean disease duration of 7.3 years and a median Expanded Disability Status Scale score of 3.75 (interquartile range 2.5–5.5; range 0–8). Twenty-six percent of these patients had a pr…

Radiative Recombination in strong laser field

2005

A theoretical treatment of the laser-assisted radiative recombination (LARR) is presented in which the low-frequency (LF) assumption is exploited. The merit of the proposed LF approximation is twofold. First, the LF approximation considerably simplifies the calculations of the transition rates, whereas the results obtained within this approximation are only slightly different from those obtained without resorting to it. Second, the LF approximation gives more insight into the physical picture of the process, which may be viewed as a two-step process. In the first step, the free electron propagates toward the ion, and its motion is described classically with motion changes ascribed mainly to…

The use of lightweight expanded clay aggregate (LECA) as sorbent for PAHs removal from water.

2012

Author's version of an article in the journal: Journal of Hazardous Materials. Also available from the publisher at: http://dx.doi.org/10.1016/j.jhazmat.2012.03.038 Lightweight expanded clay aggregate (LECA) has been explored as a sorbent for the removal of PAHs (phenanthrene, fluoranthene and pyrene) from water. The efficacy of LECA as a sorbent for PAHs was assessed using contact time, mass of sorbent and sorption isotherms in a series of batch experiments. Maximum (optimum) sorption was reached at 21 h after which the amount of PAHs sorbed remained almost constant. Batch experiments were conducted by shaking a 100 ml solution mixture of individual PAHs (containing 0.02 mg/L) with LECA. T…

Real-life impact of early interferonβ therapy in relapsing multiple sclerosis

2009

Objective: Recent findings support greater efficacy of early vs. delayed interferon beta (IFN) treatment in patients with a first clinical event suggestive of multiple sclerosis (MS). We aimed to evaluate the effectiveness of early IFN treatment in definite relapsing-remitting MS (RRMS) and to assess the optimal time to initiate IFN treatment with regard to the greatest benefits on disability progression. Methods: A cohort of 2,570 IFN-treated RRMS patients was prospectively followed for up to 7 years in 15 Italian MS Centers. A Cox proportional hazards regression model adjusted for propensity score (PS) quintiles was used to assess differences between groups of patients with early vs. dela…

The Challenge of Using CB-HSCs As Source for Gene Therapy: Lentiviral Vector Transduction, Phenotypic Characterization and Global Gene Expression Pro…

2015

Abstract Introduction: Genetic modification of autologous hematopoietic stem and progenitor cells (HSPC) is a promising clinical intervention to cure inherited monogenic diseases. Successful gene therapy trials have already been conducted using CD34+ cells from bone marrow and from mobilized peripheral blood. In this regard, cord blood (CB) represents an attractive source of HSCs due to its high concentration of high proliferative HSPC and increased susceptibility to be transduced by lentiviral vectors. Unfortunately, the major disadvantage is the limited number of HSC in the CB collection. Consequently, ex-vivo expansion of CB-HSC is desirable to extend clinical applications. Purposes: To …

Predictors of Participation and Autonomy in People With Multiple Sclerosis.

2019

Abstract Importance: Because multiple sclerosis (MS) affects many life areas, it is important to know how participation and autonomy are associated with the perceived impact of MS on everyday life. Objective: To investigate how perceived quality of life, disease impact, gender, and disease severity predict participation and autonomy in people with MS. Design: Cross-sectional study in which structural equation modeling was used to evaluate relationships between measured variables. Settings: Outpatient clinics in three areas and one inpatient rehabilitation center in Finland. Participants: Convenience sample of 194 people with MS. Outcomes and Measures: Participants completed the Impact on Pa…

Theoretical study on hydrogen storage capacity of expanded h-BN systems

2017

In this work, the hydrogen storage capacity of the expanded hexagonal Boron Nitride (eh-BN) systems has been presented. We have employed a new equation of state (EOS) for hydrogen gas to figure out the hydrogen density distribution profiles in the eh-BN systems. In this regard, the environmental conditions (i.e., temperature and pressure) are considered in the prediction procedure using DFT single point calculations. The eh-BN systems with different layer spacings are studied by PBE method with consideration of the long range dispersion corrections. On account of the in-plane polar bonds, a series of adsorption positions are considered. Additionally, the adsorption energy and hydrogen densi…
