Rheological blood behaviour is not related to gender in morbidly obese subjects.
2012
To the Editor. We have read with interest the recently published article by Wiewiora et al. [7] regarding hemorheological differences related to gender in morbidly obese subjects. In this study authors found several hemorheological differences between male and female. In this sense, males showed higher blood viscosity and higher erythrocyte deformability than females and native blood viscosity correlated with several erythrocyte aggregation parameters evaluated with the Laser-Assisted Optical Rotational Cell Analyser (LORCA) [3]. In studies with small sample sizes (18 men and 20 women) there is always the risk that differences in certain variables may appear by chance or by imbalances in th…
The Rise and Fall of Humanitarian Citizen Initiatives: A Simulation-Based Approach
2020
Citizen Initiatives for Global Solidarity (CIGS) are small, ad hoc, volunteer organizations that arise in certain humanitarian and development contexts. They operate outside of traditional aid structures and may or may not cooperate with traditional government and nongovernmental organizations. Using agent-based modeling, we derive narrative-based, qualitative scenarios from simulation data to extend the theoretical discussions of CIGS as a phenomenon. The scenarios allow further discussion of the role that CIGS may play as development and humanitarian response actors outside of the traditional context-specific descriptions of CIGS that permeate the development literature. We find that scen…
Intention to use mobile customer relationship management systems
2014
Purpose – The purpose of this paper is to investigate the behavioral intentions of business-to-business (B2B) sales managers to use mobile customer relationship management (CRM) systems in the course of their day-to-day activities. Design/methodology/approach – An extended Technology Acceptance Model (TAM) of mobile CRM system adoption is developed and tested with data from 105 international sales managers representing five B2B companies. Findings – The study extends the TAM framework with three additional constructs derived from mobile technology and sales force automation literature, namely personal innovativeness in the domain of IT, perceived risk, and perceived reachability. The model…
Targeting quality of life in asthmatic children: The MyTEP pilot randomized trial
2019
Abstract Background Quality of life (QoL) is an important outcome in the management of children with asthma. Mobile Health (m-Health) and Therapeutic Education Programs (TEPs) are increasingly recognized as essential components of pediatric asthma management to improve disease outcomes. Objective To evaluate the effect of an education program (MyTherapeutic Education Program, MyTEP) that couples multidisciplinary TEP intervention with an m-Health Program (mHP) in improving QoL in asthmatic children. Methods This single-center study employed a nonblinded randomized clinical trial design. Italian-speaking children (6–11 years) with mild-moderate asthma were eligible for participation. Partici…
Inferences on Sicilian Mesolithic subsistence patterns from cross-sectional geometry and entheseal changes
2020
International audience; Using cross-sectional geometry (CSG), entheseal changes (ECs), and presence of external auditory meatus exostosis (EAE), this study tests hypothesis-bases on isotopic and zooarchaeological evidence-that in the Sicilian Mesolithic terrestrial rather than marine resources were predominantly exploited, in substantial continuity with previous Epigravettian hunters. Results show similarities in the general frequency of ECs-a rough proxy for overall activity-with Late Pleistocene hunters, in contrast with Mesolithic coastal foragers or Neolithic herders/farmers. Yet, CSG suggests that this possible continuity in the type of resources exploited was accompanied by a behavior…
Evaluation of accuracy of various impression techniques and impression materials in recording multiple implants placed unilaterally in a partially ed…
2018
Background Various factors like implant angulation, type of impression material and tray type affects the implant impression accuracy. To date limited in-vitro studies were carried out on the implant impression accuracy of unilateral partially edentulous arches. The aim of this research was to evaluate the effects of 0o, 15o and 25o implant angulations on impression accuracy in simulated master casts of unilateral partially edentulous situation using different impression materials and tray selections. Material and Methods 30 replicas (N = 30) of a resin matrix (control) containing four implant analogues placed unilaterally from the midline till the region of second molar at an angulation of…
Changes in the Scheduling Process According to Observed Activity-travel Flexibility
2014
Abstract In this work we analyze the reasons for changing pre-planned activities and travels episodes considering the type of modification observed during the scheduling process. Specifically we selected a small sample from those pre-planned episodes that are no executed at all as a pilot study. The data analyzed was collected in the first wave of a weekly activity-travel panel survey carried out in Valencia (Spain) in 2010. Each survey wave consisted on a face-to-face interview to generate a pre-planned activity agenda for the following week, an activity-travel diary implemented on mobile phones to collect activities and travels as they are executed, and in-depth telephone interviews to in…
ACTINIDE AND ULTRA-HEAVY ABUNDANCES IN THE LOCAL GALACTIC COSMIC RAYS: AN ANALYSIS OF THE RESULTS FROM THELDEFULTRA-HEAVY COSMIC-RAY EXPERIMENT
2012
The LDEF Ultra-Heavy Cosmic-Ray Experiment (UHCRE) detected Galactic cosmic rays (GCRs) of charge Z ≥ 70 in Earth orbit with an exposure factor of 170 m2 sr yr, much larger than any other experiment. The major results include the first statistically significant uniform sample of GCR actinides with 35 events passing quality cuts, evidence for the existence of transuranic nuclei in the GCR with one 96Cm candidate event, and a low 82Pb/78Pt ratio consistent with other experiments. The probability of the existence of a transuranic component is estimated as 96%, while the most likely 92U/90Th ratio is found to be 0.4 within a wide 70% confidence interval ranging from 0 to 0.96. Overall, the resu…
Blood absorption capacity of different xenograft bone substitutes. An in-vitro study
2019
Background Commercially available xenograft blocks, claim to have adequate characteristics to interact with biological media and thus permitting biological fluid absorption. The objective of this in vitro study was to compare the blood absorption capacity of four different xenograft block materials of different composition of collagen and porosity. Material and Methods Four brands of xenograft block materials were used (NuOss®, Bio-Oss®, Osteobiol® and Smartbone®). Five samples of each brand were analyzed, making a total of 20 tests. Human blood was used as the absorption liquid for the present experiment. The time period, in which the block remains in contact with the blood, was registered…
Infection risks of city canal swimming events in the Netherlands in 2016.
2018
Introduction Swimming events in city canals are gaining popularity in the Netherlands, even though canal water is usually not officially designated for recreational use. Knowledge regarding the risk of infection after swimming in canals is limited. An outbreak was reported in 2015 following a canal swimming event in Utrecht, the Netherlands. Local governments were concerned about the health risks of such events. In order to assess the safety of canal swimming, the Public Health Service (PHS) prospectively investigated two city canal swimming events in 2015. In 2016, we repeated this study, aiming to prospectively determine the risks of infection during two urban swimming events, the Utrecht…
