Abstract: in the industrialized societies of the first world, the increasing demand for food of quality by consumers requires the food industry to produce food that not only meet the nutritional needs, but are also safe, appetizing, and healthy. there is also a growing concern in consumers about the welfare of food animals, and the impact that production, processing and distribution of food generate on the environment. these facts determine that the market changes its driving force and orientation, rewarding quality over quantity, and the food industry modifies its aims and focus from production targets towards preferential attention to consumer demands. the governments, consumers and, obviously, the industry, are increasingly aware of the influence of primary production stages on the final food quality and safety. therefore it is important to define what is meant by quality in relation to food as well as its application in the food industry.

Sensors , 2013, DOI: 10.3390/s130202051
Abstract: Private communications inside large vehicles such as ships may be effectively provided using standard cellular systems. In this paper we propose a new solution based on software-defined radio with electromagnetic sensing support. Software-defined radio allows low-cost developments and, potentially, added-value services not available in commercial cellular networks. The platform of reference, OpenBTS, only supports single-channel cells. Our proposal, however, has the ability of changing BTS channel frequency without disrupting ongoing communications. This ability should be mandatory in vehicular environments, where neighbouring cell configurations may change rapidly, so a moving cell must be reconfigured in real-time to avoid interferences. Full details about frequency occupancy sensing and the channel reselection procedure are provided in this paper. Moreover, a procedure for fast terminal detection is proposed. This may be decisive in emergency situations, e.g., if someone falls overboard. Different tests confirm the feasibility of our proposal and its compatibility with commercial GSM terminals.

International Journal of Clinical Medicine (IJCM) , 2016, DOI: 10.4236/ijcm.2016.77053
Abstract: Deficient sleep quality (SQ) has been linked with a higher hospitalization rate and mortality in dialysis patients, however the prevalence of sleep disorders and their influence on prognosis in non-dialysis chronic kidney disease (CKD) has been poorly investigated. The aim of this study was to assess factors related with SQ in CKD patients (stages I-IV) followed in a nephrology outpatient clinic as well as the long-term impact of SQ on patient’s outcome. Between January and May 2008, Pittsburgh Sleep Quality Index (PSQI) was self-administered by 122 patients (68 males and 54 females) with a mean age of 65 years. Patients were classified as “good” (global PSQI < 6) and “poor” sleepers (global PSQI ≥ 6). We identified 66 (54%) poor sleepers (PS), characterized by an older age (66 ± 14.2 vs 57 ± 17.0, p < 0.01), female predominance (59% vs 26%, p < 0.01) and worse renal function (49 ± 19.1 vs 57 ± 23.2 ml/min, p < 0.05). There was a significant correlation between phosphate and PSQI score (r = 0.234, p = 0.01), however no correlation with calcium or PTH. Vitamin D was also lower in PS (17 ± 7.2 vs 23 ± 15.1 ng/ml, p < 0.05). Until June 2015, hospitalization rate was higher among PS (64% vs 44%, p < 0.05). In this period, there was also a trend towards higher mortality for PS (18% vs 16%). In summary, over 50% of CKD patients have poor SQ, which was associated with older age, female gender, worse renal function, lower vitamin D and higher phosphate levels. Deficient sleep was associated with a greater probability of hospitalization and might be a prognostic marker in CKD.
The use of the archaeological record in the research of the celtiberian culture: the archaeological site of El Cereme o (Guadalajara, Spain)
Cerdeo, Ma Luisa
Trabajos de Prehistoria , 2008,
Abstract: Our knowledge on Celtiberian Culture have increased over the past few years. This was due to the new approaches as well as to the finding of new sites which are yielding very important archaeological information, that was lacking till recently. Among these new sites El Cereme o, and its associated cemetery, have become one of the most significant references to this culture. In the present work, the need to analyze in depth the radiocarbon dates obtained at both sites taking into account the general context of the Celtiberian Culture in the Meseta is stressed in order to avoid biases in their interpretation. Los estudios sobre la cultura celtibérica han avanzado notablemente en los últimos a os debido tanto a nuevos planteamientos, como al hallazgo de nuevos enclaves que están proporcionando importante información arqueológica, hasta hace poco tiempo deficitaria. Entre ellos, el castro de El Cereme o y su necrópolis asociada se han convertido en una de las referencias más significativas de esta cultura. En el presente trabajo se subraya la necesidad de analizar en profundidad, dentro del marco más general de la cultura celtibérica mesete a, los datos y fechas radiocarbónicas allí obtenidas para evitar desenfoques y sesgos en su interpretación.

Estudios Geologicos , 1986,
Abstract: Some characteristics of the postcraneal skeleton of Lartetotherium sansaniensis are summarized in this paper, resulting form the comparative study of the Spanish remains of this of these species and those from the type locality, Sansan (France). We have established an evolutive process involving a general decrease of size without changing proportions and morphology. We have recognized L. sansaniensis in Can Mas and Bu ol, which increases the stratigraphical and geographical distribution of this species. En este trabajo se resumen algunas características del esqueleto postcraneal de Lartetotherium sansaniensis a partir del estudio comparativo de los restos espa oles clasificados como dicha especie y los del yacimiento tipo, Sansan (Francia). Establecemos una evolución en el tiempo que implica una disminución general de la talla, manteniendo las proporciones y la morfología. Reconocemos L. sansaniensis en los yacimientos de Can Mas y Bu ol, lo cual aumenta la distribución geográfica y estratigráfica de la especie.
Quebrada Fiera (Mendoza), an important paleobiogeographic center in the South American late Oligocene
Cerdeo, E.
Estudios Geologicos , 2011, DOI: 10.3989/egeol.40519.194
Abstract: This contribution focuses on the main results and present researches on the Oligocene fauna from Quebrada Fiera (Mendoza, Argentina). This vertebrate assemblage is providing new data on the distribution and evolution of South American Deseadan (late Oligocene) mammals. Descriptions of notoungulate Notohippidae and Archaeohyracidae have been recently published. A new genus of notohippid was identified, while most archaeohyracid material was recognized as the same species present in Salla (Bolivia). Studies in progress on other native ungulates (Hegetotheriidae, Interatheriidae, Leontinidae, Homalodotheriidae, Toxodontidae, ?Proterotheriidae, and Pyrotheriidae), metatheria, xenarthra, and rodents from Quebrada Fiera will increase the knowledge of this fauna. Preliminarily, the faunal association appears as a mix of taxa. On the one hand, with Patagonian affinities, on the other hand, related to species known from lower latitudes (Bolivia), together with exclusive taxa such as Mendozahippus (Notohippidae). The ongoing research will allow a better understanding of the role of Mendoza area in the paleobiogeographic and biostratigraphic context of the South American Oligocene mammals. Esta contribución se centra en los principales resultados obtenidos en los últimos a os sobre la fauna oligocena de Quebrada Fiera (Mendoza, Argentina) y las investigaciones en curso. La asociación faunística de Quebrada Fiera está aportando datos nuevos sobre la distribución y la evolución de los mamíferos sudamericanos de la Edad mamífero Deseadense. Recientemente, se han dado a conocer los restos de dos familias de notoungulados, Notohippidae y Archaeohyracidae. En el primer caso, se reconoció un género nuevo, mientras que los arqueohirácidos se identifican en su gran mayoría como la especie presente en Salla (Bolivia). Los estudios en curso sobre otras familias de ungulados nativos (Hegetotheriidae, Interatheriidae, Leontinidae, Homalodotheriidae, Toxodontidae, ?Proterotheriidae y Pyrotheriidae), así como de los restos de metaterios, xenartros y roedores recuperados en Quebrada Fiera, ampliarán el conocimiento detallado de esta fauna. De forma preliminar, el conjunto faunístico aparece como una mezcla de taxones; por un lado, con afinidades patagónicas y, por otro, relacionados con especies conocidas en latitudes bajas (Bolivia), al mismo tiempo que cuenta con representantes exclusivos como Mendozahippus (Notohippidae). El avance de las investigaciones permitirá comprender mejor el papel del área de Mendoza en las distribuciones paleobiogeográfica y bioestratigráfica de los

Abstract: This paper synthesizes the Spanish data on Stephanorhinus hemitoechus. lt is widely distributed in middle and upper Pleistocene sites, whose geographic distribution is presented here. The best representation of the species corresponds to upper Pleistocene levels with Mousterian lithic industry. The morphological and the biometrical study of this species is carried out. Dental remains show a greater homogeneity than the postcranial material, which presents a great variation, mainly referred to the size. The Spanish S. hemitoechus seems to be smal1er sized than other European remains of the species. The Spanish reports of S. mercki, species frequently confused with S. hemitoechus, have been only confirmed in two sites, Cova Negra and Lezetxiki. Se han recopilado todos los datos referentes a la especie Stephanorhinus hemitoechus en Espa a. Se presenta su amplia distribución geográfica en yacimientos del Pleistoceno medio y superior. La mejor representación de la especie corresponde a niveles del Pleistoceno superior con industria lítica musteriense. Se ha realizado un estudio morfológico y biométrico del material. Se observa mayor homogeneidad en la dentición que en los restos postcraneales, los cuales presentan gran variación referida, sobre todo, a la talla. En conjunto, se comprueba que los restos espa oles de S. hemitoechus son más peque os que los de otros yacimientos europeos. Las citas en Espa a de S. mercki, especie frecuentemente confundida con S. hemitoechus, sólo han sido confirmadas en los yacimientos de Cova Negra y Lezetxiki.
