Analytical description of solid particles kinematics due to a fluid flow and application to the depiction of characteristic kinematics in cold sprayi…
2017
Abstract In several multiphase flow applications such as fluidization, thermal spraying, atomization manufacturing and so on, the Newton's law is widely enacted to formulate the particle/fluid kinematic interaction and then to compute particles kinematics. This paper provides analytical solutions of the Newton's law in its time-dependent formulation or simplified formulation, the latter being a reduction of the time dependent problem into a spatial description of the particle motion. It was found that the velocity solution is strictly similar in both cases so that the simplified formulation is viable. The W_ 1 branch of the Lambert's function yields the analytical particle residence time an…
Small but smart: the interaction between environmental cues and internal state modulates host-patch exploitation in a parasitic wasp
2007
International audience; The reproductive success of insect parasitoids depends on two activities, searching for hosts to obtain immediate fitness rewards (offspring) and searching for food to extend life span and enhance future reproductive opportunities. Models suggest that to deal with this trade-off and to cope with the variability of the resources they depend on, parasitoids should simultaneously integrate information originating from three distinct sources: host and food availabilities in the environment (environmental information) and the metabolic reserves of the parasitoid (internal information). We tested whether, in the parasitic wasp Venturia canescens, these three types of infor…
Biotrickling filter modeling for styrene abatement. Part 1: Model development, calibration and validation on an industrial scale
2017
Abstract A three-phase dynamic mathematical model based on mass balances describing the main processes in biotrickling filtration: convection, mass transfer, diffusion, and biodegradation was calibrated and validated for the simulation of an industrial styrene-degrading biotrickling filter. The model considered the key features of the industrial operation of biotrickling filters: variable conditions of loading and intermittent irrigation. These features were included in the model switching from the mathematical description of periods with and without irrigation. Model equations were based on the mass balances describing the main processes in biotrickling filtration: convection, mass transfe…
On Detection of Network-Based Co-residence Verification Attacks in SDN-Driven Clouds
2017
Modern cloud environments allow users to consume computational and storage resources in the form of virtual machines. Even though machines running on the same cloud server are logically isolated from each other, a malicious customer can create various side channels to obtain sensitive information from co-located machines. In this study, we concentrate on timely detection of intentional co-residence attempts in cloud environments that utilize software-defined networking. SDN enables global visibility of the network state which allows the cloud provider to monitor and extract necessary information from each flow in every virtual network in online mode. We analyze the extracted statistics on d…
Dietary Assesment of Free-Living Elderly Spanish People with Disabilities.
2017
Nutritional research in elderly disabled is difficult in noninstitutionalized people. The dietary intake of a noninstitutionalized disabled population of the eastern region of Spain was evaluated to detect possible nutritional deviations. A total of 329 participants aged 65 and over were recruited. Most participants were overweight. Carbohydrates did not reach 50% of total Kcal/day. Insufficient micronutrient intakes and high consumption of simple carbohydrates and saturated fats (SFA) were found. A decreasing trend of water intake (p < .05) as well as an increasing trend of alcohol consumption (p < .05) with increasing age was found. The area of residence had a relevant impact on nutrition…
Prevalence of intestinal parasites, with emphasis on the molecular epidemiology of Giardia duodenalis and Blastocystis sp., in the Paranaguá Bay, Bra…
2018
BACKGROUND: Intestinal protozoan parasites are major contributors to the global burden of gastrointestinal disease causing significant socioeconomic consequences. Children living in resource-poor settings with restricted access to water and sanitary services are particularly at risk of these infections. METHODS: A prospective, community-based, cross-sectional survey was conducted in Paraná (southern Brazil) between May 2015 and May 2016. A total of 766 stool samples were individually collected from volunteers (male/female ratio: 0.99; age range: 0-76 years) and used for investigating the presence of intestinal helminth and protozoan species by routine microscopic procedures including the Ka…
Thyroid Cancer in the Pediatric Age in Sicily: Influence of the Volcanic Environment.
2017
Background/Aim: Pediatric thyroid cancer (TC) is rare but its incidence is increasing. We analyzed incidence and characteristics of pediatric TC in Sicily and comparatively evaluated data from the volcanic and non-volcanic areas. Materials and Methods: All incident pediatric (0-19 years) TCs in Sicily between 2002-2009 were analyzed for the area of residence and compared to data for adults. Results: A total of 54 differentiated TCs (DTC) and nine medullary TCs were diagnosed in Sicily in children between 2002-2009. DTC age standardized rate for the world population (ASRw) was 0.8/105 in females and 0.2/105 in males, with a higher incidence in the volcanic area (ASRw=1.4/105 in females, 0.5/…

Inadequate diet influences chronic diseases such as cardiovascular disease (CVD), the leading cause of death in Spain. CVD figures vary from one geographical region to another
Preferred Music Listening Intervention in Nursing Home Residents with Cognitive Impairment: A Randomized Intervention Study.
2019
Background The current trend in addressing symptoms of dementia comprises non-pharmacological strategies such as music interventions for the management and improvement of cognitive function, memory, agitation, depression, or anxiety. Objective To determine the impact of a preferred music listening group intervention upon the functional, cognitive, and emotional dimensions in nursing home residents. Methods A randomized intervention study was carried out. The study was conducted from June to August 2015, and involved a preferred music listening group intervention lasting 60 minutes, 5 days/week during 8 weeks. A total of 119 adults aged ≥65 years, with annual permanent residence in the nursi…
Foreign Language learning and teaching Enjoyment: Teachers’ Perspectives
2019
Aim. The primary objective of the present study was to investigate the level of Foreign Language learning Enjoyment and Foreign Language teaching Enjoyment experienced by foreign language teachers in Poland. The secondary aim of the study was to investigate the sources of FLE from the perspective of FL teachers.
 Methods. The informants of the study were Polish educators teaching foreign languages at different educational levels (from primary to tertiary education). To compute the obtained quantitative data, the statistical program STATISTICA was used. Standard descriptive and inferential statistics were used to report means, median and standard deviation for sociodemographic and base…
