Comparison between hybrid moving bed biofilm reactor and activated sludge system: a pilot plant experiment

2010

The paper presents the comparison between the traditional activated sludge system (AS) and a hybrid moving bed biofilm reactor (HMBBR). In particular, an experimental campaign has been carried out at the WWTP in Palermo (Italy), on a pilot plant consisting of two pre-anoxic schemes. The aerated tank of the HMBBR line was filled with suspended carriers (AnoxKaldnes™ K1), with a 30% filling ratio. The hydraulic load of the HMBBR line was increased up to two times the AS one. Further, in order to distinguish the additional contribution of the attached biomass for the HMBBR system, in the two lines the Mixed Liquor Suspended Solids (MLSS) was maintained as equal as possible. The monitoring peri…

Influence of respiratory rate and end-expiratory pressure variation on cyclic alveolar recruitment in an experimental lung injury model

2012

Introduction Cyclic alveolar recruitment/derecruitment (R/D) is an important mechanism of ventilator-associated lung injury. In experimental models this process can be measured with high temporal resolution by detection of respiratory-dependent oscillations of the paO2 (ΔpaO2). A previous study showed that end-expiratory collapse can be prevented by an increased respiratory rate in saline-lavaged rabbits. The current study compares the effects of increased positive end-expiratory pressure (PEEP) versus an individually titrated respiratory rate (RRind) on intra-tidal amplitude of Δ paO2 and on average paO2 in saline-lavaged pigs. Methods Acute lung injury was induced by bronchoalveolar lavag…

Er:YAG laser in defocused mode for scaling of periodontally involved root surfaces: An in vitro pilot study

2005

Item does not contain fulltext BACKGROUND: The Er:YAG laser may be used on periodontally involved teeth in combination with conventional periodontal therapy in order to improve the efficacy of root instrumentation. The aim of this study was to compare the effect of hand instrumentation on root surfaces of periodontally involved teeth with Er:YAG laser application. METHODS: Thirty freshly extracted, non-carious, single-rooted, periodontally diseased human teeth from adult humans with advanced periodontal disease were used in this study. The teeth were divided into three groups of 10 specimens each. Group A was treated with scaling and root planing (SRP) with curets only (control). In group B…

Preliminary Estimation of Deoxynivalenol Excretion through a 24 h Pilot Study

2015

A duplicate diet study was designed to explore the occurrence of 15 Fusarium mycotoxins in the 24 h-diet consumed by one volunteer as well as the levels of mycotoxins in his 24 h-collected urine. The employed methodology involved solvent extraction at high ionic strength followed by dispersive solid phase extraction and gas chromatography determination coupled to mass spectrometry in tandem. Satisfactory results in method performance were achieved. The method"s accuracy was in a range of 68%108%, with intra-day relative standard deviation and inter-day relative standard deviation lower than 12% and 15%, respectively. The limits of quantitation ranged from 0.1 to 8 μg/Kg. The matrix effect w…

THE ECONOMIC INTERVENTION STRATEGY OF THE INTERNATIONAL NON-GOVERNMENTAL ORGANIZATIONS IN PALESTINE. A CASE STUDY: THE SHORT-TERM EMPLOYMENT PROJECTS

Many countries around the world, both developed and developing, are characterized by high level of unemployment. This phenomenon has profound implications not only for economic activity, by limiting the amount of labour supply and therefore potential output, but also for political and social unrest, as the experience of many Middle-Eastern and North-African economies has recently shown. Unemployment is particularly relevant for Palestine. Indeed, since the mid-1990s, Palestine is one of the countries in the world with the highest rate of unemployment. Persistently high unemployment reflect several characteristics of the Palestinian economy, mostly important the dependence on the Israeli's e…

Factors Differentiating Rural and Urban Population in Determining Anxiety and Depression in Patients with Chronic Cardiovascular Disease: A Pilot Stu…

2021

The aim of this cross-sectional study was to analyze selected variables differentiating rural from urban populations, as well as identify potentially increased levels of depression and anxiety in patients with chronic cardiovascular disease. The study was carried out in 193 patients. The study used the Camberwell Assessment of Need Short Appraisal Schedule (CANSAS), the Health Behavior Inventory Questionnaire (HBI), the WHOQOL-BREF Quality of Life Questionnaire, and the Hospital Anxiety and Depression Scale–Modified Version (HADS-M). Spearman’s rank correlation coefficient test and logistic regression were used for analyses. In rural patients, we observed a relationship between anxiety and …

Luoghi urbani scomparsi e architetture mai realizzate nella riconfigurazione 3D del Rione Conceria di Palermo

2018

L'oggetto di studio è lo scomparso Rione Conceria all'interno del Centro Storico di Palermo. È una vasta area urbana, che si estende lungo la Via Maqueda, Via Roma, Corso Vittorio Emanuele e Via Bandiera, che storicamente faceva parte di un unico sistema urbano che cuciva il mercato del Capo con il Mercato della Vucciria. Le operazioni urbanistiche del secolo scorso (il taglio di via Roma, il il progetto di riorganizzazione dell'intero rione, la costruzione della Galleria delle Vittorie) hanno cancellato quasi definitivamente sia le sue presenza architettoniche che l'impianto del suo tessuto viario. The object of study is the disappeared Rione Conceria inside the Historical Center of Palerm…

Nursing students' perceptions of a video-based serious game's educational value: A pilot study.

2018

Abstract Background Despite an increasing number of serious games (SGs) in nursing education, few evaluation studies specifically address their educational value in terms of face, content, and construct validity. Objectives To assess nursing students' perceptions of a video-based SG in terms of face, content, and construct validity. In addition, the study assessed perceptions of usability, individual factors, and preferences regarding future use. Design A pilot study was conducted. Setting and Participants An SG prototype was implemented as part of two simulation courses in nursing education: one for home health care and one for hospital medical-surgical wards. The SG aimed to teach clinica…

Governance of Projects: Generating value by linking projects with their permanent organisation

2019

Abstract There exists little research into how value is effectively generated by temporary projects from the wider perspective of a permanent organisation. This paper investigates empirically how ‘Governance of Projects’ – the way in which a single, permanent organisation identifies, creates, and subsequently harvests value through multiple projects – occurs in four private-sector case companies. Data were collected from in-depth interviews with a wide range of employees and from internal operational documents. These data were codified and analysed as evidence of the types and intensity of links between organisational elements. The results illuminate the complex interplay of links that are …
