Kilohertz and Low-Frequency Electrical Stimulation With the Same Pulse Duration Have Similar Efficiency for Inducing Isometric Knee Extension Torque …
2017
International audience; Objective To test the hypotheses that, as compared with pulsed current with the same pulse duration, kilohertz frequency alternating current would not differ in terms of evoked-torque production and perceived discomfort, and as a result, it would show the same current efficiency.Design A repeated-measures design with 4 stimuli presented in random order was used to test 25 women: (1) 500-microsecond pulse duration, (2) 250-microsecond pulse duration, (3) 500-microsecond pulse duration and low carrier frequency (1 kHz), (4) 250-microsecond pulse duration and high carrier frequency (4 kHz). Isometric peak torque of quadriceps muscle was measured using an isokinetic dyna…
Chicago e la tradizione dei vetri decorativi: Louis Comfort Tiffany e Frank Lloyd Wright
2012
Pensando all’arte sviluppatasi in America a cavallo tra Ottocento e Novecento non possono non venire in mente le figure di Louis Comfort Tiffany e Frank Lloyd Wright, due grandi protagonisti di quel tempo passati alla storia come pionieri, il primo nell’ambito delle arti decorative e il secondo nello specifico architettonico, ma ancora oggi fonte di ispirazione per designer all’avanguardia.
Fuzzy motion control strategy for cooperation of multiple automated vehicles with passengers comfort
2008
This paper considers motion control for a cooperative system of automated passenger vehicles. It develops a cooperative scheme based on a decentralized planning algorithm which considers the vehicles in an initial open chain configuration. In this scheme the trajectories are intersections-free, and each trajectory is planned independently of the others. To ensure the stabilization of each vehicle in the planned trajectory, a fuzzy closed loop motion control is presented, where, based on the properties of the Fuzzy maps, the Lyapunov’s stability of the motion errors is demonstrated for all the vehicles. Based on the ISO 2631-1 standard, the saturation property of the Fuzzy maps guarantees lo…
METODI E STRUMENTI PER LA VALUTAZIONE DEL COMFORT VISIVO
2012
Il corretto svolgimento del compito visivo viene garantito dalle adeguate condizioni del microclima luminoso in ambiente, che risultano fondamentali per la produttivita del soggetto. Nella ricerca, si e evidenziato come alcuni dei parametri di valutazione degli ambienti, illuminati naturalmente, attualmente utilizzati, nel caso oggetto dello studio, come il Daylight Factor medio [%] e il fattore di uniformita, richiedano una applicazione critica e mirata, affinche possano fornire un quadro qualitativo completo delle condizioni reali dell’ambiente. Frequentemente, a causa di alcuni gradi di liberta all’interno degli intervalli di accettabilita definiti dalla normativa, la descrizione, comune…
Spasmolytic Effects of Aphanizomenon Flos Aquae (AFA) Extract on the Human Colon Contractility.
2021
The blue-green algae Aphanizomenon flos aquae (AFA), rich in beneficial nutrients, exerts various beneficial effects, acting in different organs including the gut. Klamin® is an AFA extract particularly rich in β-PEA, a trace-amine considered a neuromodulator in the central nervous system. To date, it is not clear if β-PEA exerts a role in the enteric nervous system. The aims of the present study were to investigate the effects induced by Klamin® on the human distal colon mechanical activity, to analyze the mechanism of action, and to verify a β-PEA involvement. The organ bath technique, RT-PCR, and immunohistochemistry (IHC) were used. Klamin® reduced, in a concentration-dependent manner, …
Measurements of projected areas of seated and standing people of southern Italy based on a statistical analysis
2006
One of the most important components affecting the human thermal balance is represented by its radiative exchange with the surrounding surfaces. The projected area of the human body is an important parameter of these thermal exchanges. Unfortunately, although the anthropometric measures of people are characterized by significant differences among various populations, the experimental data currently available in the literature refers to a small group of people. Moreover, measurements are generally performed regardless of the statistical significance of the involved subjects with respect to the population to which they belong. In this study, a statistical study is introduced that is based on …
Mediating role of job satisfaction, affective well-being and health in the relationship between indoor environment and absenteeism: work patterns mat…
2018
BACKGROUND: Office workers spend long hours in their workplace, and these environments impact their well-being and performance. This relationship can involve different mediation chains. The degree of complexity of this relationship can vary depending on different types of office work (work patterns) employees carry out. OBJECTIVE: To analyze the relationship between indoor environment and absenteeism, and the mediating role of job satisfaction, affective well-being, and health, in different work patterns. METHOD: 1306 office workers from different European countries were classified into work patterns depending on: task complexity and interactivity. RESULTS: Job satisfaction, affective well-…
Using food comfortability to compare food's sensory characteristics expectations of elderly people with or without oral health problems
2017
International audience; Food consumption is by far the most important point where food's organoleptic properties can be perceived and can elicit sensory pleasure. Ageing is often accompanied by oral impairments. Those impairments may impact food perception by changing texture perception and the release of flavor components, which have a significant impact on food acceptability. The present study aimed at evaluating the impact of oral health on the perception of food comfortability in an elderly population. This was achieved by asking elderly people with a good oral health and elderly people with poor oral health to rate six cereal products and six meat products using a food comfortability q…
Fixation free femoral hernia repair with a 3D dynamic responsive implant. A case series report
2018
Abstract Background To date, no gold standard for the surgical treatment of femoral hernia exists. Pure tissue repair as well as mesh/plug implantation, open or laparoscopic, are the most performed methods. Nevertheless, all these techniques need sutures or mesh fixation. This implies the risk of damaging sensitive structures of the femoral area, along with complications related to tissue tear and postoperative discomfort consequent to poor quality mesh incorporation. The present retrospective multicenter case series highlights the results of femoral hernia repair procedures performed with a 3D dynamic responsive implant in a cohort of 32 patients during a mean follow up of 27 months. Mater…
Multiobjective optimization of building energy consumption and thermal comfort based on integrated BIM framework with machine learning-NSGA II
2022
Detailed parametric analysis and measurements are required to reduce building energy usage while maintaining acceptable thermal conditions. This research suggested a system that combines Building Information Modeling (BIM), machine learning, and the non-dominated sorting genetic algorithm-II (NSGA II) to investigate the impact of building factors on energy usage and find the optimal design. A plugin is developed to receive sensor data and export all necessary information from BIM to MSSQL and Excel. The BIM model was imported to IDA Indoor Climate and Energy (IDA ICE) to execute an energy consumption simulation and then a pairwise test to produce the sample data set. To study the data set a…
