Classificació automàtica amb KLASS de les dades de procés d'una EDAR

In this study an automatic cluster is done on data froma a Waster Water Treatment Plant to obtain specific knowledge of an ill-structured domain like biological wastewater treatment process. The whole process requires the supervision of the expert of the process. This clustering is done using KLASS, which allows to deal simultaneously with numerical and symbolic variables in the description of objects. From this automatic classification, we obtain a set of clusters that can be labelled as typical operational states. All the knowledge and information acquired will be constitute the initial library of a case base reasoning system that together with expert system constitute a decision support system for this WWTP.Postprint (published version

In Vitro Propagation Studies on the Initial and Establishment Stages of Rubber (Hevea Brasiliensis Muell. Arg.)

Development of in vitro methods to propagate rubber is highly desirable. Some procedures exist but they generally do not address well the initial and establishment stages. This leads to minimal arrest of two common deterrents in any micropropagation system, i.e., contamination and browning. This project attempted to study both contamination and browning phenomena with an aim of improving survival without altering regeneration of explants. Field materials of clone RRIM 600 were used. Experiments on the Initial and Establishment stages, their interactions and concluding experiments were conducted. In all experiments, explants were cultured in the standard tissue culture procedures on basic MS medium. In the Initial stage, the results showed no significant difference between chemical treatments of antibiotics and/or fungicide in the field and control. As for the physical characteristics, efficient initial measures were to use 6-week old middle portions or shoot tips. This could be improved by growing these explants in a glasshouse. In the Establishment stage, the most efficient procedure to decontaminate explants was Procedure E that included a succession of treatments with ethanol, Clorox, Rifampicin, Ampicillin, DMSO and Triton-X before culturing. Regarding debrowning treatments, the best overall responses were obtained by culturing explants in MS medium (half strength) modified by the addition of 4 mg/L silver nitrate. In the analysis of the interactions between treatments in the Initial and Establishment stages, results showed that the combination of treatments with better potential was the one that included the use of mature explants (6-week old) surface decontaminated by Procedure E

Sociocrititical Implications in Nutrition:Diet Vs Feeding

Diet and feeding are two terms used as synonyms in society and in the practice of professionals in feeding, nutrition, dietetics and health, however, by contrasting both concepts in their various dissertations in the most explored fields of science, differences are remarkable to understand that, while diet is a habit determined by economics, politics and law, socially learned towards food consumption for biopsychosocial satisfaction, influenced by culture, education and society, as opposed to feeding that it is a process of care, selection, transformation and distribution of food influenced by neoliberal policies, through socio-political and economic interests, which when entering into debate, not only transgresses more than a process of food transformation, but rather satisfaction of a need or the right to health, where the practice and its concept is reinvented alignment according to the context or regionalization with an impact on health. This is how an interaction is built not only between individual-collective-diet/feeding but also formal and informal elements that influence this process are integrated, marketing, media-social and political interests, the health/disease/care process, as well as the social reality, the scientific reality, the processes and preconceptions, condition a game between norms and purposes, where their implications on health of the individual and the collective are influenced in a negative or positive way in the form to get sick and dying

A Narrative Review of Protective Factors that Predict Enculturation Processes for Latinx Individuals in the U.S.

A Narrative Review of Protective Factors that Predict Enculturation Processes for Latinx Individuals in the U.S. Jane Sun, Dept. of Psychology, Jennifer Rodriguez, Alanna Cason, Yessica Flores, Karl Villareal, Arlenis Santana, Dept. of Psychology Graduate Student, & Chloe Walker, Dept. of Psychology Graduate Student, with Dr. Chelsea D. Williams, Dept. of Psychology According to the 2010 U.S. Census, the rise of immigration led the Latinx community to experience the largest population growth amongst all ethnic-racial groups (Sanchez et al., 2012). Enculturation is the process of preserving heritage cultural values while enduring the influence of the current, surrounding culture (Schwartz et al., 2013). Enculturation is a subcomponent in the broad spectrum of acculturation, the process through which the introduction of two differing cultures induces cultural changes (Rodriguez et al., 2002). While current research has focused on the protective factors involved in the acculturative process, minimal research has centered on the protective factors in enculturation amongst the Latinx community. The aim of the current narrative review was to identify the protective factors (e.g., language, values, generational differences, group membership) associated with enculturation of Latinx U.S. citizens. Implications will discuss the promotion of social awareness within the Latinx community.https://scholarscompass.vcu.edu/uresposters/1333/thumbnail.jp

Can smartwatches replace smartphones for posture tracking?

This paper introduces a human posture tracking platform to identify the human postures of sitting, standing or lying down, based on a smartwatch. This work develops such a system as a proof-of-concept study to investigate a smartwatch's ability to be used in future remote health monitoring systems and applications. This work validates the smartwatches' ability to track the posture of users accurately in a laboratory setting while reducing the sampling rate to potentially improve battery life, the first steps in verifying that such a system would work in future clinical settings. The algorithm developed classifies the transitions between three posture states of sitting, standing and lying down, by identifying these transition movements, as well as other movements that might be mistaken for these transitions. The system is trained and developed on a Samsung Galaxy Gear smartwatch, and the algorithm was validated through a leave-one-subject-out cross-validation of 20 subjects. The system can identify the appropriate transitions at only 10 Hz with an F-score of 0.930, indicating its ability to effectively replace smart phones, if needed
