Energy analysis and heat loads calculation approach: application to agrifood industrial premises

Nowadays, the agrifood industry is increasingly concerned about energy bills. Thus, there is an increasing trend on the implementation of measures and procedures that ensure and promote energy efficiency. Computational modelling is a powerful tool for project and design of engineering systems, allowing to anticipate and/or correct problems that may lead to inefficiencies. The purpose of this paper is to assess the energy performance of refrigerated premises of a real company modelled in EnergyPlus. The data that characterize the company and the production process were collected previously through an energy audit. Results of the comparison between real case and simulation show that the cooling system represents 56.4% and 47.8% of the total electrical energy consumption, respectively. Also, it is found that heat transmission loads trough cold rooms envelope and air infiltration are those that most affect the energy performance, accounting for almost 80% of the refrigeration needs of the company.info:eu-repo/semantics/publishedVersio

Consumer Behaviour in Fitness Club: Study of the Weekly Frequency of Use, Expectations, Satisfaction and Retention

This study aims to understand the relationship between the weekly frequency of use, expectations, satisfaction and retention of members in a fitness Clubs. In this market it is indispensable to understand the characteristics of faithful members, in order to act appropriately with each segment. Accordingly, the weekly frequency, which a member goes to the gym, their expectations, satisfaction and retention are key variables to understand them. Data was collected with a sample of 146 members. The instrument was constituted by the sample characterization and questions to understand the consumer behaviour in fitness (weekly frequency of use, expectations, satisfaction and retention behaviours). The statistical analysis consisted on descriptive and inferential analyses, using SPSS software. In this study the weekly frequency did not show the explanatory capacity to predict the satisfaction and retention. The relationship between expectations with satisfaction (73%) and retention (64%) was statistically significant. Finally, the relationship between satisfaction and retention (63%) was positive and significant. The results indicated that fitness club managers must act to keep those who are less likely to remain, who aren’t the ones who go less times a week to the club, but those who have a lower satisfaction and, consequently, lower retention.info:eu-repo/semantics/publishedVersio

MUSCULAR FATIGUE DURING 200 M FRONT CRAWL

The purpose of this study was to evaluate muscle fatigue in upper and lower limbs as well as trunk muscles during a 200 m all-out front crawl effort. Surface electromyogram was collected from the flexor carpi radialis, biceps brachii, triceps brachii, pectoralis major, trapezius pars superior, rectus femoris, biceps femoris and tibialis anterior of 13 international level male swimmers. Velocity, stroke frequency and stroke length were calculated based on 3D video analysis. Spectral Indices of Muscle Fatigue (IMF) were calculated for each stroke of the each 25 m lap. During the 200 m, the rate of IMF changed against the first lap and increased gradually across successive laps, reflecting the evolvement of muscle fatigue for all studied muscles

No fate but what we make: a case of full recovery after out-of-hospital cardiac arrest

An 80 years old man suffered a cardiac arrest shortly after arrival to his local health department. Basic Life Support was started promptly and nine minutes later, on evaluation by an Advanced Life Support team, the victim was defibrillated with a 200J shock. When orotracheal intubation was attempted, masseter muscle contraction was noticed: on revaluation, the victim had pulse and spontaneous breathing

Field results on developed three-phase four-wire shunt active power filters

Abstract-This paper presents three-phase four-wire Shunt Active Power Filters with ability to compensate current harmonics, power factor, and current unbalance. The power stage of the Active Power Filters is based on a two-level four-leg inverter. The switching technique is based on an optimized periodic sampling strategy, and the digital controller uses the Theory of Instantaneous Reactive Power (p-q Theory) expanded for three- phase four-wire systems. The presented Active Power Filters were successfully demonstrated in four different facilities. The presented experimental results show the performance of the Active Power Filters in operation with very different load profiles

An antisocial alchemy: Psychopathic traits as a moderator of the different forms and functions of aggression in delinquency and conduct disorder among youth

The aim of the present study is to examine the possible role of psychopathic traits as a moderator of the aggression-antisociality/delinquency link. Our sample was composed of 567 youth (M = 15.91 years, SD = 0.99 years, age range = 14-18 years) from Portugal. Results indicated that psychopathic features significantly moderate four different forms and functions of aggression - proactive overt, proactive relational, reactive overt, and reactive relational - when predicting delinquency. However, psychopathic traits only significantly moderate proactive relational aggression when predicting Conduct Disorder. Psychopathic traits and aggression constitute an antisocial alchemy for antisocial behavior but more research is needed about moderation effects therein particularly among clinical and justice system involved samples of youth to inform behavioral interventions.info:eu-repo/semantics/publishedVersio

CENTRE OF MASS INTRACYCLIC VELOCITY VARIATION IN THREE VARIANTS OF THE FRONT CRAWL WATER POLO TECHNIQUE

The purpose of this study was to analyse the intracyclic velocity variation (IVV) of the centre of mass (CM) in the x, y, z axes during the stroke cycle event in front crawl, water polo front crawl and water polo front crawl while leading the ball. Ten national level water polo players performed 3x15 m at maximum intensity in each variant of the front crawl technique, being videotaped by six cameras (two above and four underwater). One complete stroke cycle was analyzed for each 15 m test using the APASystem. The numerical treatment was conducted using MATLAB software. IVVx and IVVz showed less variation in the water polo front crawl, and IVVy showed less variation for the water polo front crawl leading the ball. These suggest that water polo players have a greater proficiency in water polo specific swimming techniques rather than in front crawl
