Human response to vibration in residential environments, technical report 1 : measurement of vibration exposure
The Technical Report 1 describes the research undertaken to develop a method by which human exposure to vibration in residential environments can be assessed. That work has been carried out by the University of Salford supported by the Department of environment food and rural affairs (Defra). The overall aim of the project is to derive exposure-response relationships for human vibration in residential environments. This document in particular focuses on the equipment and methodology employed to measure vibration from different sources.
The main objective of this report is to describe the practical experience of implementing a vibration measurement protocol. Reported here are findings obtained in the field measurements and a description of a feasible method for measuring vibration for different sources. In addition, controlled tests performed to determine the suitability of the vibration mounting for various practical situations are reported
Mental Maps as a Strategy in the Development of Successful Intelligence in High School Students
Mind maps are usually employed by teachers from all the educational levels as powerful learning strategies. This use enables important pedagogic achievements, but they do not exceed their maximum level, due to the dogmatic use of Tony Buzan's mind map (1996). Situation that would be different if it were entirely internalized, understand and applied. Precisely for that reason, the triarchic theory of intelligence developed by Rober Sternberg (1985) allows students to make decisions in several difficult situations with the suitable use of techniques and orientations in the development of the same intelligence. The research was developed by means of the case study from the qualitative focus, in which through the analysis of the evidences found and the use of an instrument that measured the successful intelligence, its development could be confirmed. However, the empiric analysis was not enough for validating the aforementioned development. For that reason, direct observation was chosen during learning sessions accomplished by the teacher responsible for the strategy to be used, and embodied in the field notebook. Likewise, in-depth interviews were conducted by educational psychologists. It should be noted that the analyzed documents have allowed developing the triangulation not only of evidences but also of methodologies, among them the documentary analysis, in order to reach conclusions that demonstrate how the development of the successful intelligence has been achieved. Finally, it is demonstrated than the use of the techniques of the mind maps with an educational strategy adapted to the applied group, achieves the significant development of the abilities of the analytical, creative and practical intelligence
Effect of Zinc Supplementation on Growth of Low Birth Weight Infants Aged 1–6 Mo in Ardabil, Iran
Objective To assess the effect of zinc supplementation on growth of low birth weight (LBW) infants aged 1–6 mo. Methods LBW infants were enrolled at birth and randomly assigned to receive 5 mg elemental Zn per day (n=45) or placebo (n=45) until 6 mo of age. They were followed monthly for information on compliance; anthropometric measurements were performed monthly. Results After randomization, 5 infants from zinc group and 9 from placebo group were excluded. At 6 mo of age, significantly greater weight gains were observed in the zinc than in the placebo group (4995±741g in zinc group vs. 3896±865 g in placebo group, p = 0.036). Length gain during the study period improved in zinc group (16.9±8.2 cm vs. 15.1±4.1 cm, p = 0.039); after zinc supplementation head circumference were increased (8.7±1.4 cm vs.7.4±
1.5 cm p<0.001). In male infants, total weight gain and height and head circumference gain were higher in the zinc than in the placebo group. However, only head circumference change was statistically significant. A similar trend was observed among female infants, but these differences were not statistically significant. There was no significant relation between breast-feeding status and the main outcome variables. Conclusions Infants in the present study showed improve¬ments in growth rate, but more studies are required in this field to confirm this fact
Los colibr?s explotadores de la lectura
60 P?ginasLa lectura de cuentos, es uno de los instrumentos m?s eficaces para ayudar al ni?o a desarrollar su lenguaje como posibilidad de acceso a la cultura y una comprensi?n mayor del mundo nuevo que lo rodea, a trav?s de situaciones, personajes y lugares reales o imaginarios. Al crear espacios donde el ni?o pueda acceder al universo ling??stico, se permite el dominio de las palabras, de los s?mbolos verbales que representan los objetos, las cualidades y acciones que el ni?o necesita manejar para comunicarse con los adultos y otros ni?os. En este proceso su lenguaje interior se ir? conformando, as? se sentir? seguro, feliz y podr? disfrutar est?ticamente del discurso literario.
Se abordar? el cuento infantil como estrategia pedag?gica orientada desde el lenguaje de s?mbolos, desarrollando la comprensi?n e interpretaci?n a trav?s del texto, permitiendo acceder a un mundo dinamizador del proceso literario y redescubrir las posibilidades que brinda la experiencia educativa. En el grado primero, se han realizado diferentes actividades en las cuales las palabras generadoras y los objetos simb?licos han jugado un papel importante, ya que se busca en ellos potenciar la argumentaci?n oral y escrita; estas actividades han dado una respuesta positiva, ya que de forma activa ellos pueden participar de las actividades en las cuales se hace una interdisciplinariedad con todas las ?reas; dada la necesidad de emprender con los estudiantes del primer grado de B?sica Primaria del Colegio Arquidiocesano Nuestra Se?ora del Sagrado Coraz?n, la ense?anza de la lengua materna, a partir de la literatura.ABSTRACT. Reading stories, is one of the most effective tools to help children develop their language as a possibility of access to culture and one understanding of the new world that surrounds it, characters and real or imaginary places. To create spaces where the child can access the linguistic universe, the domain of the words allowed, the domain of the words allowed, the verbal symbols that represent the objects, the qualities and actions that the child needs to manage to communicate with adults and other children. In this process its internal language will be creating, so feel safe, happy and enjoy aesthetically literary discourse.
The fairy tale as a pedagogical strategy from the language of symbols will be addressed, developing understanding and interpretation through the text, allowing access to a dynamic world of the literary process and rediscover the possibilities afforded the educational experience. In first grade, performed different activities in which the generating words and symbolic objects have played an important role, Since you are looking for in them promote oral and written argumentation, These efforts have met with a positive response, Since actively they can participate in activities in which there is an interdisciplinary approach in all areas given the need to undertake with the first graders of elementary basic College Archdiocesan our Lady of the sacred heart College Archdiocesan our Lady of the sacred heart.

Large introns in relation to alternative splicing and gene evolution: a case study of Drosophila bruno-3
Background:
Alternative splicing (AS) of maturing mRNA can generate structurally and functionally distinct transcripts from the same gene. Recent bioinformatic analyses of available genome databases inferred a positive correlation between intron length and AS. To study the interplay between intron length and AS empirically and in more detail, we analyzed the diversity of alternatively spliced transcripts (ASTs) in the Drosophila RNA-binding Bruno-3 (Bru-3) gene. This gene was known to encode thirteen exons separated by introns of diverse sizes, ranging from 71 to 41,973 nucleotides in D. melanogaster. Although Bru-3's structure is expected to be conducive to AS, only two ASTs of this gene were previously described.
Results:
Cloning of RT-PCR products of the entire ORF from four species representing three diverged Drosophila lineages provided an evolutionary perspective, high sensitivity, and long-range contiguity of splice choices currently unattainable by high-throughput methods. Consequently, we identified three new exons, a new exon fragment and thirty-three previously unknown ASTs of Bru-3. All exon-skipping events in the gene were mapped to the exons surrounded by introns of at least 800 nucleotides, whereas exons split by introns of less than 250 nucleotides were always spliced contiguously in mRNA. Cases of exon loss and creation during Bru-3 evolution in Drosophila were also localized within large introns. Notably, we identified a true de novo exon gain: exon 8 was created along the lineage of the obscura group from intronic sequence between cryptic splice sites conserved among all Drosophila species surveyed. Exon 8 was included in mature mRNA by the species representing all the major branches of the obscura group. To our knowledge, the origin of exon 8 is the first documented case of exonization of intronic sequence outside vertebrates.
Conclusion:
We found that large introns can promote AS via exon-skipping and exon turnover during evolution likely due to frequent errors in their removal from maturing mRNA. Large introns could be a reservoir of genetic diversity, because they have a greater number of mutable sites than short introns. Taken together, gene structure can constrain and/or promote gene evolution
The Main Belt Comets and ice in the Solar System
We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout the Solar System, and describe the various methods for detecting it, including remote sensing from ultraviolet to radio wavelengths. We review progress in the first decade of study of MBCs, including observations, modelling of ice survival, and discussion on their origins. We then look at which methods will likely be most effective for further progress, including the key challenge of direct detection of (escaping) water in these bodies
