Coordinating heterogeneous IoT devices by means of the centralized vision of the SDN controller

The IoT (Internet of Things) has become a reality during recent years. The desire of having everything connected to the Internet results in clearly identified benefits that will impact on socio economic development. However, the exponential growth in the number of IoT devices and their heterogeneity open new challenges that must be carefully studied. Coordination among devices to adapt them to their users' context usually requires high volumes of data to be exchanged with the cloud. In order to reduce unnecessary communications and network overhead, this paper proposes a novel network architecture based on the Software-Defined Networking paradigm that allows IoT devices coordinate and adapt them within the scope of a particular context.Universidad de Málaga.

Cecchi, Italy Nowadays, pollinosis is affecting a large percentage of population in the countries with a western life style. The existence of allergenic activity in the atmosphere is not only associated to pollen grains and fungal spores, but also to submicronic and paucimicronic biological particles. The origin of these allergens can be due to the rupture of pollen transported in the atmosphere or to the presence of allergens from other parts of the plant making amorphous material with an allergen load. Olive pollen is recognized as one of the main causes of allergic disease in the Mediterranean area. In this study we have tried to compare olive pollen count in the air and Ole e 1 as major allergen of this species, at two different localities in South of Europe: Evora (Portugal) and Córdoba (Spain). At each location both samplers were placed side-by-side. Pollen grains have been sampled using a volumetric Hirst type spore trap. Chemvol high-volume cascade impactor equipped with stages PM>10µm, 10 µm>PM>2.5µm were used for detecting aeroallergens. Ole e 1 major allergen was determined using allergen specific ELISA´s. Similar behaviour between pollen and the total allergenic load was observed during the pollen season. Nevertheless, at some occasions, during the previous and later period of the pollen season, airborne allergenic load was detected in South Spain, due to the contributions from other Oleaceae species. For this reason the use of these two different methodologies allow a better understanding of the allergenic load in the atmosphere.

Moderate alcohol drinking is not associated with risk of depression in older adults

The scarce research on the effects of moderate alcohol consumption on mental health among older adults suggests a protective effect against depression. We prospectively examined the association between patterns of moderate alcohol consumption, depression and psychological distress, using information from 5, 299 community-dwelling older adults from the ELSA and Seniors-ENRICA cohorts. A Mediterranean drinking pattern (MDP) was defined as moderate alcohol intake (<40 g/day for men; <24 g/day for women) with a preference for wine and drinking only with meals. Depression was ascertained with the 10-item Geriatric Depression Scale (GDS-10), a self-report of clinically-diagnosed depression, or being on anti-depressant medication (Seniors-ENRICA); and with the 8-item Center for Epidemiologic Studies Depression Scale (CES-D) (ELSA). Psychological distress was assessed with the General Health Questionnaire-12 (GHQ-12). Compared to never drinkers, moderate drinkers showed comparable scores on the ENRICA-GDS-10 (PRR (95%CI): 1.03 (0.84–1.26)), the ENRICA-GHQ-12 (0.88 (0.73–1.06)), the ELSA-CES-D (0.92 (0.79–1.06)) and the ELSA-GHQ-12 (0.75 (0.55–1.01). The MDP was not associated with the GDS-10 or GHQ-12 scores, or with clinically-diagnosed depression; however drinkers with a preference for wine showed an increased number of psychological distress symptoms (1.31 (1.03–1.66)). In conclusion, we found no consistent protective association between moderate alcohol consumption and depression in older adults

Prenatal exposure to persistent organic pollutants and anogenital distance in children at 18 months

Background: Anogenital distance (AGD) is a measure of in utero exposure to hormonally active agents. The aim of the present study was to evaluate the association between prenatal exposure to persistent organic pollutants (POPs) and AGD. Methods: POP levels were measured in pregnant women, and the AGD was recorded in 43 offspring at 18 months. We used linear regression models to analyze the association between maternal POP exposure and offspring AGD. We defined the anogenital index (AGI) as AGD divided by weight at 18 months (AGI = AGD / weight at 18 months [mm/kg]) and included this variable in the regression models. Results: AGI measure was 2.35 (0.61) and 1.38 (0.45) in males and females, respectively. AGI was inversely associated with lipid-adjusted concentrations of PBDE-99 (β = -0.28, 95% confidence interval [CI]: -0.51, -0.04) and PBDE-153 (β = -0.61, 95% CI: -1.11, -0.11) in males. We did not find any statistically significant relationship between any POPs and AGI in females. Conclusions: Environmental exposure to POPs may affect genital development and result in reproductive tract alterations with potentially relevant health consequences in maturity. © 2018 The Author(s).

Fragmentos para una etnografía de las radios comunitarias e indígenas en América Latina

In this paper we are interested in highlighting the existence of extended communities based on the social, political, and cultural use that the actors involved in community and indigenous radio stations in Latin America make of these media. For this, we resort to the presentation of three ethnographic cases. From Chiapas (Mexico), we look at the dialogic process of indigenous communication and the value of the word to generate community. On the other hand, we analyze the different strategies that indigenous and community radio stations follow in the search and expression of identities in the Quebrada de Humahuaca and the Puna de Jujuy (Argentine Northwest). Finally, we address the questioning of gender relations raised by female communicators from Bolivia. In all cases, our purpose is to interpret how the radio experience is capable of creating new communities.En este artículo nos interesa resaltar la existencia de comunidades ampliadas a partir del uso social, político y cultural que los actores implicados en las radios comunitarias e indígenas de América Latina hacen de estos medios. Para ello recurrimos a la presentación de tres casos etnográficos. Desde Chiapas (México), nos fijamos en el proceso dialógico de la comunicación indígena y en el valor de la palabra para generar comunidad. Por otra parte, analizamos las distintas estrategias que en la búsqueda y expresión de las identidades siguen las radios indígenas y comunitarias en la Quebrada de Humahuaca y la Puna de Jujuy (Noroeste argentino). Por último, abordamos el cuestionamiento de las relaciones de género planteado por mujeres comunicadoras de Bolivia. En todos los casos, nuestro propósito es el de interpretar cómo la experiencia de la radio es capaz de crear nuevas comunidades
