Evaluation through adaptive model (ATC) in the levels of thermal comfort in summer in offices in Mediterranea locations.

The design of the building-plant system in the case of office buildings has rarely considered the adaptive model of comfort almost always limited to the control of temperature and humidity and only in some cases of PMV and PPD. Specifically when the building interacts with a climate characterized by high values of external temperature and humidity for long periods, and with high solar radiation in the presence of large glazed areas, it is crucial to take into account relevant aspects of the principle of thermal adaptation. The long stay of the occupants in an air-conditioned environment leads, at the request of colder temperatures very distant from those indicated by the criteria of acceptability of an environment from those occurring at the same moment outside the building, characterizing in this way, a greatly exceeding to negative values with respect to static model of comfort. By using of the adaptive model, the occupant of a building is no longer simply understood as a passive subject, as it appeared in the static model of Fanger, but as an active agent that interacts at all levels with the environment in which stays. This article shows an experimental study, which shows that the results of this model defines comfort temperatures greater and more flexible than the model of Fanger, even with significant energy savings on air conditioning in summer

A Mathematical Model For Evaluating Energy Consumptions In Life Cycle Assessment.

This paper takes up the ecobalance topic giving prominence to a calculation procedure of necessary energy consumptions for the production of a product in the different phases of a whole life cycle. Are used to identify all stages of the life cycle are determined and simplified formulas for the calculation of specific energy consumption. Is also examined a case where the components of the final product are up to 8. The model is valid for any type of product and through operations research (ie, placing constraints on the variables) you could get to optimal solutions minimizing the objective function

Systemic Treatment of Pediatric Psoriasis: A Review.

Psoriasis is a chronic, immune-mediated, inflammatory skin disease, affecting 1-3% of the white population. Although the existence of two psoriasis incidence peaks has been suggested (one in adolescence before 20 years of age and another in adulthood), its onset may occur at any age, including childhood and adolescence, in which the incidence is now estimated at 40.8 per 100,000. As for adult psoriasis, pediatric psoriasis has recently been associated with obesity, metabolic syndrome, increased waist circumference percentiles and metabolic laboratory abnormalities, warranting early monitoring and lifestyle modifications. In addition, due to psoriasis' chronic nature and frequently occurring relapses, psoriatic patients tend to have an impaired quality of life, often requiring long-term treatment. Therefore, education of both pediatric patients and their parents is essential to successful and safe disease management. Given the lack of officially approved therapies, the very limited evidence-based data from randomized controlled trials, and the absence of standardized guidelines, to date, pediatric psoriasis treatment is primarily based on published case reports, case series, guidelines for adult psoriasis, expert opinions and experience with these drugs in other pediatric disorders coming from the disciplines of rheumatology, gastroenterology and oncology. This review focuses on the use of systemic treatments in pediatric psoriasis and their specific features, analyzing the few literature evidences available, expanding the treatment repertoire and guiding dermatologists in better managing of recalcitrant pediatric psoriasis

The Origin and Early Evolution of Sauria: Reassessing the Permian Saurian Fossil Record and the Timing of the Crocodile-Lizard Divergence

Sauria is the crown-group of Diapsida and is subdivided into Lepidosauromorpha and Archosauromorpha, comprising a high percentage of the diversity of living and fossil tetrapods. The split between lepidosauromorphs and archosauromorphs (the crocodile-lizard, or bird-lizard, divergence) is considered one of the key calibration points for molecular analyses of tetrapod phylogeny. Saurians have a very rich Mesozoic and Cenozoic fossil record, but their late Paleozoic (Permian) record is problematic. Several Permian specimens have been referred to Sauria, but the phylogenetic affinity of some of these records remains questionable. We reexamine and review all of these specimens here, providing new data on early saurian evolution including osteohistology, and present a new morphological phylogenetic dataset. We support previous studies that find that no valid Permian record for Lepidosauromorpha, and we also reject some of the previous referrals of Permian specimens to Archosauromorpha. The most informative Permian archosauromorph is Protorosaurus speneri from the middle Late Permian of Western Europe. A historically problematic specimen from the Late Permian of Tanzania is redescribed and reidentified as a new genus and species of basal archosauromorph: Aenigmastropheus parringtoni. The supposed protorosaur Eorasaurus olsoni from the Late Permian of Russia is recovered among Archosauriformes and may be the oldest known member of the group but the phylogenetic support for this position is low. The assignment of Archosaurus rossicus from the latest Permian of Russia to the archosauromorph clade Proterosuchidae is supported. Our revision suggests a minimum fossil calibration date for the crocodile-lizard split of 254.7 Ma. The occurrences of basal archosauromorphs in the northern (30°N) and southern (55°S) parts of Pangea imply a wider paleobiogeographic distribution for the group during the Late Permian than previously appreciated. Early archosauromorph growth strategies appear to be more diverse than previously suggested based on new data on the osteohistology of Aenigmastropheus
