Effect of the season on the free phytoprostanes content in Cornicabra extra virgin olive oil from deficit irrigated olive trees

BACKGROUND: The effect of regulated deficit irrigation (RDI) on the phytoprostane (PhytoP) content in extra virgin olive (Olea europaea L., cv. Cornicabra) oil (EVOO) was studied. During the 2012 and 2013 seasons, T0 plants were irrigated at 100% ETc, while T1 and T2 plants were irrigated avoiding water deficit during phases I and III of fruit growth and saving water during the non-critical phenological period of pit hardening (phase II), developing amore severewater deficit in T2 plants. In 2013, a fourth treatment (T3) was also performed, which was similar to T2 except that water saving was from the beginning of phase II to 15 days after the end of phase II. RESULTS: 9-F1t-PhytoP, 9-epi-9-F1t-PhytoP, 9-epi-9-D1t-PhytoP, 9-D1t-PhytoP, 16-B1-PhytoP and 9-L1-PhytoP were present in Cornicabra EVOO, and their contents increased in the EVOO fromRDI plants. CONCLUSION: Deficit irrigation during pit hardening or for a further period of 2 weeks thereafter to increase irrigation water saving is clearly critical for EVOO composition because of the enhancement of free PhytoPs, which have potential beneficial effects on human health. The response of individual free PhytoPs to changes in plant water status was not as perceptible as expected, preventing their use as biomarkers of water stress.

Determinación del riesgo de incendio en una instalación de secado de alperujo = Determination of the risk of fire in an olive-oil mill waste dryer

For the energy valorization of alperujo, residue of the olive oil two phases extraction process, it is necessary to perform a drying process to reduce moisture content from over 60% to less than 10%. In order to reduce primary energy consumption and get an economic return, usually in this kind of drying facilities Gas Turbine CHP is used as a heat source. There have been recently in Spain some fires in this kind of GT-CHP facilities, which have caused high material losses. In some of these fires it has been suggested that the fire was caused by the output of incandescent alperujo in the flue gasesof the drying system. Therefore, the aim of this study is to determine experimentally and analytically under which operational conditions a process of alperujo self-ignition in the drying process can begin, and determine the actual fire hazard in this type of TG-CHP system. For analytical study, the temperature and initial composition of the combustion gases of the Gas Turbine at the entrance of the drying process was calculated and the gas equilibrium conditions reached in contact with the biomass were calculated and, therefore, the temperature of the biomass during the drying process. Moreover, the layer and dust ignition temperature of alperujo has been experimentally determined, according to EN 50281-2-1: 2000. With these results, the operating conditions of the drying process, in which there are real risk of auto-ignition of alperujo have been established.Para la valorización energética del alperujo, residuo del proceso de extracción en dos fases del aceite de oliva, es necesario realizar un proceso de secado para reducir su contenido de humedad de más del 60% al 10% m/m en b.h. Con el fin de reducir el consumo de energía primaria y obtener una rentabilidad económica, normalmente en este tipo de instalaciones de secado se usa la cogeneración con turbina de gas (TG) como fuente de calor. En España en los últimos años han ocurrido algunos casos de incendio en este tipo de instalaciones de cogeneración, que han supuesto pérdidas materiales muy elevadas. Por esta razón, el objetivo de este trabajo es determinar analítica y experimentalmente las condiciones operativas del secadero bajo las cuales podría comenzar un proceso de autoinflamación del alperujo y determinar el riesgo real de incendio en este tipo de instalaciones. Para el estudio analítico, se ha planteado y validado el modelo matemático que permite calcular la temperatura y la composición de los gases de combustión a la entrada y a la salida del secadero, en función de las curvas características de la TG, de las condiciones atmosféricas, del caudal y del grado de humedad de la biomasa tratada. El modelo permite además calcular la temperatura de bulbo húmedo, que es la máxima temperatura que podría alcanzar la biomasa durante el proceso de secado y determinar la cantidad de biomasa que se puede secar completamente en función del caudal y de las condiciones de entrada de los gases de combustión. Con estos resultados y la temperatura mínima de autoinflamación del alperujo determinada experimentalmente siguiendo la norma EN 50281- 2-1:2000, se demuestra que en un proceso de secado de alperujo en condiciones normales de operación no existe riesgo de autoencendido que pueda dar origen a un incendio.

Interlibrary loan in primary access libraries: challenging the traditional view

Introduction: Primary access libraries serve as the foundation of the National Network of Libraries of Medicine (NN/LM) interlibrary loan (ILL) hierarchy, yet few published reports directly address the important role these libraries play in the ILL system. This may reflect the traditional view that small, primary access libraries are largely users of ILL, rather than important contributors to the effectiveness and efficiency of the national ILL system.

Multiple paternity in two natural populations (orchard and vineyard) of Drosophila.

Male mating success is an important fitness component in Drosophila. The seminal fluid conveyed with the sperm inhibits the proclivity of the female to remate and reduces her fitness. Nevertheless, females may remate before they have exhausted the sperm from the first male and consequently use sperm from both males. We have studied concurrent multiple paternity (CMP) in two Drosophila melanogaster populations, from an apple orchard and a vineyard just after harvest. CMP is high in both populations, somewhat greater than 50%; but it is not significantly higher in the vineyard, where the population density is much greater than in the orchard. Population density had been thought to be an important determinant of CMP incidence. We have used four gene loci coding for enzymes as independent markers for detecting CMP.

The Trail of No Tears: Traditional Masculinity Ideologies and The Cycle of Dismissing-Avoidant Attachment

Raising boys in accordance with traditional masculinity ideologies is creating a mental health crisis among men. Socialization in accordance with traditional male gender roles causes boys to develop dismissing-avoidant attachments with their primary caregivers. Approaching subsequent relationships with a dismissing-attachment style creates disconnection between men and male peers, female partners, and their children. Many researchers advocate clinical interventions that perpetuate men's traditional fears of intimacy, however attachment theory provides an alternative lens through which clinicians may approach therapy with men. By engaging men in therapeutic attachment relationships, clinicians can inspire implicit and explicit learning of new attachment patterns. This experience by nature challenges traditional definitions of masculinity, and men may develop more congruent, adaptive, and healthy definitions of masculinity.

Reducing Stigma toward Sexual Minorities: Acceptance-Based versus Traditional Safe Zone Training.

Homophobia continues to exist in society. Homonegative attitudes are often implicit and can be acquired without direct training, which makes them particularly resistant to change. Relational Frame Theory (RFT) is a behavior analytic account of learning processes and can explain these processes of indirect learning. RFT also suggests therapeutic processes for dismantling stigma using a therapy model named Acceptance and Commitment Therapy (ACT). This paper reviews previous research on traditional multicultural training, and addresses its shortcomings. Specifically, this paper makes the argument that traditional models encourage experiential avoidance and thus further perpetuate the processes that maintain stigma. While a handful of studies have examined stigma interventions using ACT, no ACT studies have been completed specifically on the stigma towards gay and lesbian individuals. This paper concludes with a research proposal for such a study.

A Self Psychological Conceptualization for Traditional Gender Role Men and Considerations in Couples Treatment

The study of masculinity and its impact on men’s psychological development and subsequent functioning has become more prevalent in the last few decades. This area of research has begun to introduce psychological interventions specific to men in treatment settings. Masculinity, like any socially constructed phenomena, is a fluid concept with overlapping variables and characteristics that are specific to what is learned from one’s social, cultural, and familial environment. According to Tremblay & L’Heureux (2005):

Cultural conflict: Conveyance of traditional Iranian values and the effects on sense of self of Iranian-American women

The literature on Iranians who immigrated to countries with modern cultures is sparse. This paper presents a theoretical understanding of the research with a particular appreciation on issues related to gender roles, sexuality, and acculturation within this population. In addition, treatment suggestions with this Iranian immigrant population will be presented through the lens of self psychology and a new perspective about the effects on the sense of self of young immigrant Iranian females will be discussed.

EmotiBlog: a fine-grained model for emotion detection in non-traditional textual genres

This paper presents the first version of EmotiBlog, an annotation scheme for emotions in non-traditional textual genres such as blogs or forums. We collected a corpus composed by blog posts in three languages: English, Spanish and Italian and about three topics of interest. Subsequently, we annotated our collection and carried out the inter-annotator agreement and a ten-fold cross-validation evaluation, obtaining promising results. The main aim of this research is to provide a finer-grained annotation scheme and annotated data that are essential to perform evaluation focused on checking the quality of the created resources.

Machine learning techniques for automatic opinion detection in non-traditional textual genres

This paper presents a preliminary study in which Machine Learning experiments applied to Opinion Mining in blogs have been carried out. We created and annotated a blog corpus in Spanish using EmotiBlog. We evaluated the utility of the features labelled firstly carrying out experiments with combinations of them and secondly using the feature selection techniques, we also deal with several problems, such as the noisy character of the input texts, the small size of the training set, the granularity of the annotation scheme and the language object of our study, Spanish, with less resource than English. We obtained promising results considering that it is a preliminary study.

Going beyond traditional QA systems: challenges and keys in opinion question answering

The treatment of factual data has been widely studied in different areas of Natural Language Processing (NLP). However, processing subjective information still poses important challenges. This paper presents research aimed at assessing techniques that have been suggested as appropriate in the context of subjective - Opinion Question Answering (OQA). We evaluate the performance of an OQA with these new components and propose methods to optimally tackle the issues encountered. We assess the impact of including additional resources and processes with the purpose of improving the system performance on two distinct blog datasets. The improvements obtained for the different combination of tools are statistically significant. We thus conclude that the proposed approach is adequate for the OQA task, offering a good strategy to deal with opinionated questions.

The role of children in the traditional religious house-blessing rite of Salpassa in north-eastern Spain

Salpassa denotes the blessing of houses, land, and other belongings, carried out during Easter week and Resurrection (Easter) Sunday in the Valencia–Catalonia linguistic region of north-eastern Spain. Although it is now remembered mostly as a consecrating ceremony or a religious rite, recent field research has shown that a playful element, carried out by children through their songs and other activities, was also an important aspect of the traditional Salpassa.
