No full textPreliminary bioassays on the susceptibility of stone fruits rootstocks to Capnodis tenebrionis (L.).
No full textCapnodis tenebrionis (L.) (Coleoptera: Buprestidae), the so called Mediterranean flat-headed root-borer, is an economically important phytophagous pest species mainly on stone fruit trees (apricot, plum, cherry, peach and nectarine). Chemicals and Entomopathogenic nematodes are used for the control of adults and neonate larvae, respectively. Further control means are under investigations in order to have more options within Integrated Pest Control strategies. This study is aimed at investigating the susceptibility of rootstocks to the larvae of C. tenebrionis. Two bioassays were carried out during 2016 and 2017. A first bioassay was based on the evaluation of a potential antixenosis action expressed by neonate larvae infesting twigs of rootstocks (Marianna 26, Barrier, Adesoto, Mylaboran 29C, GF677, Garnem, Cab 6P, Max Ma60 and Colt). This bioassay allowed to process a high number of different rootstocks in a short time. It has a preliminary value. The second bioassay assessed the antibiosis influence of the rootstocks through the breeding of larvae (since the neonate ones) on artificial diets containing bark flour of Adesoto, Cab 6P, Colt, Garnem, GF677, Max Ma60, Montclar and 29C rootstock. The first bioassay showed that Colt, Mylaboran 29C and GF677 were the most susceptible rootstocks to larval infestation of C. tenebrionis and Max Ma60 was less favorable to the pest. Concerning the effects of the diet, larvae reared on a diet containing Montclar, Cab 6P and GF 677 bark flour had a mean daily increase of their weight higher that those reared on cortex tissues of other genotypes whereas Garnem and Colt had a lower increase

No full textCHANGES IN ENJOYMENT OF PHYSICAL ACTIVITY, ACTUAL AND PERCEIVED PHYSICAL ABILITIES IN PRIMARY SCHOOL CHILDREN
No full textEnjoyment of physical activity (PA), actual and erceived physical abilities are important factors in promoting active lifestyles and regular PA among children, but little research has investigated these relationships over time. The aim of the study was to examine changes in these variables in primery school children involved in an additional physical education lessons program (2 times week). Tests involving the standing long jump, 1 kg medicine-ball throw, 10x 4 m shuttle run, basketball throw and 20m sprint were administered before (T0) and after (T1) a 4-month intervention in 178 boys and 184 girls aged 8 to 10 years. Enjoyment and levels of PA were assessed using the Physical Activity Enjoyment Scale (PACES) and the Physical Activity Questionnaire for Older Children (PAQ-C), respectively. Individual's perceptions of strenght, speed, and agility were measured using the Perceived Physical Ability Scale for Children (PPAS_C). -significant time effects were found, with participants reporting higer PA (p<.0,5), enjoyment (p<.0,1), and actual and perceived physical ability (p<.001) scores at T1 compared to T0. Main effects were also obtained for gender, with boys showing better performances (p<.001), and higher values in the PPAS_C and PACES (p<.01) than girls. Findings support the feasibility and efficacy of the school-based intervention for improving PA levels, enjoyment, and perceived and actual physical abilities of children
Designing Courses in Modeling and Identification of Dynamic Systems for Real-Time Assessment
No full textIn undergraduate engineering education, particularly in the area of control systems, it is vital for students to gain knowledge on the identification of linear systems. Undergraduate students need to be equipped with both theoretical understanding and practical skills in this field. The key to achieving this goal is creating an effective course design that maximizes student learning outcomes by promoting active learning and integrating diverse instructional strategies and resources. In response to this educational requirement, the present work aims at describing the design of an undergraduate course on the modeling and identification of dynamic systems based on a blended learning approach. Thanks to the course design, the traditional educational experience allows for additional practice exercises and laboratory experiments exploiting the virtual learning environment. Moreover, the integration of the online environment also enables the personalization of learning by means of automated formative and summative assessments of student learning. Initial findings from the course implementation underscore the efficacy of the blended learning approach in eliciting student engagement, offering promising implications for educational practices and pedagogical strategies
