Types of Scolytidae and Platypodidae (Coleoptera: Curculionoidea) housed at the Museo de La Plata entomological collection

This contribution refers to the type material of Scolytidae and Platypodidae (Coleoptera: Curculionoidea) housed at the Museo de La Plata collection. The specimens examined were mostly syntypes of Scolytidae, corresponding to species described by the German specialist Karl Schedl, from 1938 to 1958. They come from Argentina and were collected by the entomologists M. J. Viana, J. M. Bosq, and C. Bruch. We have examined more than 2000 specimens regarded as types, however, after the comparison of the information of their labels with that of the original species descriptions, only 308 of them were recognized as “true types”. They correspond to 46 nominal species (43 of Scolytidae and three of Platypodidae), currently assigned to 23 genera. For each species we provide the following information: original and valid names, bibliographic references, category of types, code-numbers according to the rules of the Museo de La Plata collection, sex of the specimens when it is indicated, data on the labels (exact transcriptions), and remarks.Esta contribución se refiere al material tipo de Scolytidae y Platypodidae (Coleoptera: Curculionoidea) depositado en la colección del Museo de La Plata.

A new approach for the validation of conceptual holonic constructions

The concepts of holon and holarchy were first applied in the manufacturing world to develop Holonic Manufacturing Systems. Since then, they have been used in many fields and have proved to be applicable concepts for developing applications in any business area. Resulting applications are based on conceptual holonic constructions. Like any model, a holarchy needs to be validated under real circumstances. Such validation assures the quality of the holarchy before it is implemented. In general, validation research tends to target: 1) the specific types of holons handled in each proposal and/or the selected development paradigms; and 2) algorithm performance rather than architecture quality. This paper proposes and evaluates a methodology that focuses on the quality of the architecture. This methodology is able to validate any holonic architecture built to meet trade requirements. Moreover, this is a general-purpose methodology. Therefore, the methodology would be valid for any domain and would not be invalidated by holon types and/or implementation paradigms emerging, changing or falling into disuse. For this purpose, we consider holonic architectures as conceptual models, using the pure holon and holarchy concepts and passing up not only any specific implementation paradigm but also any set of specific holon types

Amifostina. Un tratamiento alternativo contra el cáncer.

La Amifostina [ácido S-2-(3-aminopropilamino) etiolfósforotioico)], prodroga que al desfosforilarse por la fosfatasa alcalina produce el WR1065 [2-(3_aminopropilamino) etanotiol], actúa como atrapador de radicales libres (RL). Su empleo frente al cisplatino, agente que genera RL durante su acción, podría disminuir el daño a las células normales que captan selectivamente la prodroga. Se evaluó la capacidad de la amifostina a diferentes dosis sobre la peroxidación lipídica (TBARS) y la actividad de las enzimas antioxidantes superóxido dismutasa (SOD) y catalasa (CAT) en el tejido renal. Las dosis más efectivas fueron las más bajas, con las que se obtienen la menor concentración de TBARS y la menor actividad SOD y CAT. El modelo es una propuesta para evaluar el efecto citoprotector de la amifostina desde el nivel molecular al tisular.  Palabras clave: Amifostina, peroxidación lipídica; superóxido dismutasa; catalasa

High-Performance Handball Player’s Time-Motion Analysis by Playing Positions

The purpose of this study was to analyze the on-court demands of handball players during the European Handball Federation Champions League Final Four (VELUX EHF FINAL4) 2019 to define time–motion characteristics (played time; covered distances) both in offense and defense. Furthermore; we aimed to define position-specific demands and differences among them. Forty players from three teams were analyzed during the tournament using a local positioning system (LPS) for the first time in top handball. Players covered similar distances both in offense (1388.28 ± 2627.08 m), and in defense (1305.47 ± 5059.64 m) and remained on court for a similar average time (15.69 ± 8.02 min and 15.40 ± 8.94 min respectively). When locomotion activities were normalized according to the time they spent on court; significant differences were found for defense compared to offense in walking (+20%; p < 0.000; Cohen’s effect size (ES) = 1.01) and jogging (−29.6%; p = 0.000; ES = 0.90), as well as a tendency for high-intensity running (+ 25.2%; p = 0.077; ES = 0.31). Per playing position; center and left back (CB = 94.86 ± 10.98 m·min−1 ; LB = 96.55 ± 24.65 m·min−1 ) showed the highest running pace in offense and mid-left; front center defender and outside right for the defense (ML = 90.38 ± 30.16 m·min−1 ; FCD = 87.04 ± 14.94 m·min−1 ; OR = 89.64 ± 34.93 m·min−1 ). In conclusion; profile differences existed among players’ position activity; both in offense and defense; which should be taken into account when designing specific physical training programs.MINECO/FEDER 20928/PI/18Consejo Superior de Deportes PID2019-108336GB-10024/UPB/1

An architectural model for software testing lesson learned systems

Software testing is a key aspect of software reliability and quality assurance in a context where software development constantly has to overcome mammoth challenges in a continuously changing environment. One of the characteristics of software testing is that it has a large intellectual capital component and can thus benefit from the use of the experience gained from past projects. Software testing can, then, potentially benefit from solutions provided by the knowledge management discipline. There are in fact a number of proposals concerning effective knowledge management related to several software engineering processes. Objective: We defend the use of a lesson learned system for software testing. The reason is that such a system is an effective knowledge management resource enabling testers and managers to take advantage of the experience locked away in the brains of the testers. To do this, the experience has to be gathered, disseminated and reused. Method: After analyzing the proposals for managing software testing experience, significant weaknesses have been detected in the current systems of this type. The architectural model proposed here for lesson learned systems is designed to try to avoid these weaknesses. This model (i) defines the structure of the software testing lessons learned; (ii) sets up procedures for lesson learned management; and (iii) supports the design of software tools to manage the lessons learned. Results: A different approach, based on the management of the lessons learned that software testing engineers gather from everyday experience, with two basic goals: usefulness and applicability. Conclusion: The architectural model proposed here lays the groundwork to overcome the obstacles to sharing and reusing experience gained in the software testing and test management. As such, it provides guidance for developing software testing lesson learned systems

Cross‐sectional study about impact of parental smoking on rhinitis symptoms in children

[Abstract] Objective. Assess the prevalence of rhinitis and exposure to environmental tobacco smoke (ETS) of children in our community and its relationship with symptoms of rhinitis Methods (design, setting, participants, main outcome measures). Cross‐sectional study using questionnaire on rhinitis of the International Study of Asthma and Allergies in Childhood, in children (6‐7 years) and adolescents (13‐14 years). Categories: “rhinitis ever”, “recent rhinitis”, “recent rhinoconjunctivitis”, “severe rhinoconjunctivitis”. Parental smoking: (i) neither parent smokes; (ii) only the mother smokes; (iii) only the father smokes; and (iv) both parents smoke. Odds ratio of the prevalence of symptoms of rhinitis according to ETS exposure was calculated using logistic regression. Results. 10 690 children and 10 730 adolescents. The prevalence of “rhinitis ever” in children: 29.4%, “recent rhinitis” 24%, “recent rhinoconjunctivitis” 11.5% and “severe rhinoconjunctivitis” 0.1%. In adolescents: 46.2%, 34.5%, 16.2% and 0.2%, respectively. Environmental tobacco smoke exposure in the home occurred in 51% of cases. Parental smoking was associated with a higher prevalence of forms of rhinitis in adolescents when only the mother was a smoker. In children when both parents were smokers. Conclusion. Rhinitis is highly prevalent in our community. Environmental tobacco smoke exposure is still very common. The relationship between ETS and rhinitis symptoms in children of this community is not as robust as that found for asthma
