This text will highlight the human specificity of burials and their religious and cultural institutionalization. This symbolic singularity, accredited since ancient times in the homo species, involves an awareness of death and the post mortem life that will cross all cultural eras of humanity. Where human makes presence, respect for the dead in their graves also appears. It will also reveal continuity between the notion of grave and the temple, where both spaces are considered sacred and religious venues. [ABSTRACT FROM AUTHOR]

The present article explores the possibility of understanding social ethics as an ethics of the future, in the sense that this will be that which allows the time set aside for living to make sense; because this depends on the moral quality of the real future that arises before the ethical question of: what should I do to have a good life? For this it is considered that the approach of capabilities, in a moral sense, as developed by Adela Cortina in her concept of cordial ethics and cordial justice, by which each individual becomes a valid interlocutor to know, estimate and feel values, converges and it requires, the conception of the radical choice of being oneself as Kierkegaard has proposed, so that they are truly capacities with a moral character for time and do not remain only in the instrumental or procedural sphere of ethics. This work exposes first the approach and outline of the moral capacities of a cordial justice in Adela Cortina and, secondly, how is that the conception of the radical choice of becoming oneself in the thought of Kierkegaard, finally gives to these capacities its fundamental ethical sense in time.

The temperatures of atmospheric air at 850 millibars are modeled to determine their potential as an indicator of heat waves in northwest Mexico. The analysis was performed at meso-scale level but focused on the city of Mexicali, Mexico. The main variables that cause the formation of a heat wave are identified, and the modeling of air temperature at 850 milibars as an indicator of its development. This is done considering eight climate variables, using six artificial intelligence algorithms. The numerical technique of artificial neural networks showed a better performance, obtaining a regression coefficient of 0.76 with a pvalue of 0.0019. It is concluded that this non-linear model is a promising tool that could be used in a warning system of this dangerous atmospheric phenomenon. [ABSTRACT FROM AUTHOR]

BACKGROUND: CO2 laser has been the laser of choice in laryngology for decades and has served as a reference for the development of new types of laser. OBJECTIVES: To analyze the characteristics of CO2 and other types of available lasers, as well as to demonstrate de usefulness of photoangiolytic lasers, specifically KTP, for microphonosurgery. MATERIAL AND METHODS: We reviewed medical literature searching for the otolaryngologic applications of the different types of available lasers, primarily in thefield of laryngology. A comparative analysis -was then conducted: between CO2 and photoangiolytic lasers and between the two most commonly used photoangiolytic lasers: PDL vs KTP. The practical use of these lasers was demonstrated with clinical cases. RESULTS: CO2 laser has a high absorption affinityfor -water, for that it is highly ejfectiveforfine tissue cutting and bloc resections. Photoangiolytic lasers, specifically KTP laser, have a high absorption affinity for oxyhemoglobin, so they are a useful alternative for vascular and tumoral lesions that are in intimate contact with the delicate vocal fold epithelium. CONCLUSIONS: Photoangiolytic lasers, specifically KTP, must be considered a useful alternative in vascularized laryngeal lesions. This particular type of laser offers great advantages over CO2 laser, as lowering the risk of inadequate scarring as well as maintaining the integrity ofvocal fold epithelium and superficial laminapropria (SEP).

Parvovirus B19 (B19) is the only known human pathogenic parvovirus. The spectrum of illness to which B19 is associated includes a wide range of diseases: erythema infectio- sum, thrombocytopenia or granulocytopenia, aplastic crisis or hemolytic anemia in immunocompromised patients. The laboratory diagnosis of Parvovirus B19 infection is primarily conirmed by the detection of IgM antiviral antibodies using the ELISA technique, which is directed against both conformational and linear epitopes of VP1 and VP2 capsid. When IgM response declines, an IgG immune-response against structural proteins VP1 and VP2 becomes prominent and can detected by immunoluorescence, ELISA and Western blot. Polymerase chain reaction is now used as a routine analysis as well as complement or alternative to serology. [ABSTRACT FROM AUTHOR]

We have used a feather to study light diffraction, in a qualitative as well as in a quantitative manner. Experimental measurement of the separation between the bright spots obtained with a laser pointer allowed the determination of the space between feather's barbs and barbules. The results we have obtained agree satisfactorily with those corresponding to a typical feather. Due to the kind of materials, the related concepts and the experimental results, this activity becomes an excellent didactic resource suitable for studying diffraction, both in introductory undergraduate as well as in secondary school physics courses.

The halo of relativism around the work of art, left behind by Postmodernism, illuminates the work's meaning and its truth; however, also found under this light is the urgency of reclaiming the artistic importance of the work, and not of the subject This article addresses these questions in relation to other activities that share the same creative nature: music, architecture, or paining. Essentially, the work of art is a spatial-temporal entity, and as such, it comes to life acquiring its being, its meaning, and its evolution - as does the very subject itself. [ABSTRACT FROM AUTHOR]

This work presents the evaluation of the process of using a virtual learning platform designed ad hoc for Music Education in Secondary. Our goal is to analyze the use of this platform through the techniques of Educational Data Mining (EDM) so that we study the application of data mining to data collected with Learning Management System (LMS). These techniques allow us to understand the behavior of the data during the process of teaching and learning in online learning environments, which provides the ability to monitor activities to optimize their performance, correct learning deficiencies, detect anomalous behavior of certain groups of activity (outliers) and improve the design of online teaching-learning activities. The analytical techniques we use in research are oriented to clean the information and selection of significant variables in the study and to use cluster analysis and cluster type and predictive rules from the behavior of the data collected. The results we obtain show that the activities that have accumulated the most records have been exploratory types: “to see the subject of discussion” and “see the discussion forum”; the student body has spent most of time exploring those tools. The most intense activity has been generated by communication tools such as forums and chats where we have recorded the majority of students’ musical learning. [ABSTRACT FROM AUTHOR]

Entre los procedimientos de creación léxica utilizados en la lengua del Derecho Penal durante los Siglos de Oro se encuentran los mecanismos de derivación. Estos meca- nismos son especialmente interesantes, pues no solo han permitido afinar la expresión de ciertos conceptos, sino tambidn renovar algunas de las más antiguas denominaciones, sentando asi las bases de La modema terminologia juridico-penal.

This paper is intended to explore the advances developed in a line of research in assessment of ICT in Music Education in High Schools. We present an educational experience in a Secondary school from Spain. We have designed a sociocultural pedagogical model for Music Education with ICT, which is based on the use of a learning management system. We have tested the design of computer platform used for musical learning through expert judge, evaluating the process of using the platform with qualitative and quantitative techniques, on the other hand we have tested the evaluation of impacts of the educational model in students, through the analysis of a system of categories on the audio and video recordings of musical performances by the students, a focus group formed by the participating students and three scales about work, learning and attitude. Finally, we have studied the attitude improvement with learning model. The high level of control in the evaluation of the teaching and learning process allows us to discuss the creation of a knowledge management system, through which musical learning is generated. Students learn to learn by themselves and through the construction of knowledge through collaborative learning process, giving support roles, self-learning, developing autonomy and self-regulation. The results have been very positive and suggest the transfer of Music Education experience to other schools. [ABSTRACT FROM AUTHOR]

Optimum percentage of Bos taurus (BT) genes in crossbreed cows under humid tropical conditions was determined based on milk yield variables: milk yield per lactation (MYL); MY per day (MYD); MY per day of calving interval (MYCI); peak MY (PMY); MY per day of herd life (MYDHL); days at peak MY (DPMY); and lactation persistency (LP). Data were collected at a commercial dual-purpose farm in Tabasco State, Mexico, and included 1220 full (270-d) lactations from 577 cows with BT and Bos indicus (BI) genes percentages ranging from pure breed to 7/8BI:1/8BT. Analysis was done with a mixed model that included the fixed effects of calving number, year and season, the random effects of sire and cow within sire, and the BT gene percentage as a covariable. First-calving cows had lower (P<0.05) MYL, MYD, MYDCI, PMY and LP values than secondcalving cows, and the latter had lower values than third-calving cows. The highest (P<0.05) MYL (2,898.3) value was observed in 78.0 % BT cows and the highest MYD (9.8 kg) in 70.3 % BT cows. Both variables exhibited decreased returns after their respective peaks. The highest (P<0.05) MYDHL (2.3 kg) and MYDCI (6.9 kg) were observed in 50 or 61 % BT cows. Cows in the 50 to 80 % BT range exhibited the most positive milk yield performance, however, when milk yield was analyzed in association with reproductive traits and management practices 50 and 60 % BT cows exhibited the best performance.

This article is about the theory of passions of three important philosophers of modernity: Descartes, Spinoza and Hume. It is intended to show the content of what these authors conceive as the motor of moral action. Each one, in his particular style, connects the theme of passions with his own theory about experience and the aim of action. It is a theoretical route of the passionate conceived as what marks the emancipation of modern self. [ABSTRACT FROM AUTHOR]

This article explores two decades of Mexican government graduate studies policies (1988-2008). Graduate studies have expanded notably in that time, offering a wider variety of topics, an expansion accompanied by the emergence of evaluation policies whose systems and indicators tend heavily to the quantitative. Among other things, this has accentuated these policies' inequalities and processes of institutional and functional differentiation. [ABSTRACT FROM AUTHOR]

This paper has researched the role of diminutive suffixes in Literature and, especially, in the 19th century Spanish novel. Based on the example of an important thesis novel of the period (Galdos' Doña Perfecta), the research findings have shown that the narrator's usage of diminutive suffixes reinforces the author's criticisism of the intolerance and religious fanaticism common among the Spanish conservative social classes in the second half of the nineteenth century. In fact, diminutive suffixes have an axiological nature which turns them into a very useful rethorical device in order to achieve persuasion. [ABSTRACT FROM AUTHOR]
