    The synthesis, infra-red, Raman and NMR spectra and crystal structure of 2, 4, 4- trimethyl-4, 5- dihydro-3H-benzo[b] [1, 4] diazepin-1-ium tetrachlorocadmate, [C12H17N2]2CdCl4 and benzene-1,2-diaminium decachlorotricadmate(II) [C6H10N2]2Cd3Cl10 are reported. The [C12H17N2]2CdCl4 compound crystallizes in the triclinic system (P-1 space group) with Z = 2 and the following unit cell dimensions: a = 9.6653(8) angstrom, b = 9.9081(9) angstrom, c = 15.3737(2) angstrom, alpha = 79.486(1)degrees, beta = 88.610(8)degrees and gamma = 77.550(7)degrees. The structure was solved by using 4439 independent reflections down to R value of 0.029. In crystal structure, the tetrachlorocadmiate anion is connected to two organic cations through N-H...Cl hydrogen bonds and Van Der Waals interaction as to build cation-anion-cation cohesion. The [C6H10N2]2Cd3Cl10 crystallizes in the triclinic system (P-1 space group). The unit cell dimensions are a = 6.826 (5)angstrom, b = 9.861 (7)angstrom, c = 10.344 (3)angstrom, alpha = 103.50 (1)degrees, beta = 96.34 (4)degrees and gamma = 109.45 (3)degrees, Z=2. The final R value is 0.053 (Rw=0.128). Its crystal structure consists of organic cations and polymeric chains of [Cd3Cl10]4- anions running along the [011] direction, In The [C6H10N2]2Cd3Cl10 compounds hydrogen bond interactions between the inorganic chains and the organic cations, contribute to the crystal packing.

    Identification of functional elements and regulatory circuits by Drosophila modENCODE

    To gain insight into how genomic information is translated into cellular and developmental programs, the Drosophila model organism Encyclopedia of DNA Elements (modENCODE) project is comprehensively mapping transcripts, histone modifications, chromosomal proteins, transcription factors, replication proteins and intermediates, and nucleosome properties across a developmental time course and in multiple cell lines. We have generated more than 700 data sets and discovered protein-coding, noncoding, RNA regulatory, replication, and chromatin elements, more than tripling the annotated portion of the Drosophila genome. Correlated activity patterns of these elements reveal a functional regulatory network, which predicts putative new functions for genes, reveals stage- and tissue-specific regulators, and enables gene-expression prediction. Our results provide a foundation for directed experimental and computational studies in Drosophila and related species and also a model for systematic data integration toward comprehensive genomic and functional annotation

    Educators’ Experiences Teaching Literary Journalis: Insights Gained from Five Years of Web-Based Surveys

    To support international literary journalism as a discipline, and for the discipline to reach its full potential, it may be helpful to understand how literary journalism is being taught. As John S. Bak states, “[t]he steady production of strong criticism, theory, and pedagogy will eventually coalesce the literary journalism that is out there now and create the discipline’s niche” (BAK, 2017, p. 236). In this article, we investigate questions about teaching literary journalism from both a broad and narrow perspective. In what countries, universities, departments, and classes is literary journalism taught, and how is it being taught? What methods and texts are used? What challenges do educators face, and how do they meet those challenges? These are just some of the questions that we have attempted to address here by surveying educators online annually since 2011 (with the exception of one year, 2013). The purpose of this article is to summarize some of what we have learned through these web-based surveys. We hope that readers will digest what is offered here, ask questions, discuss with colleagues, and consider future lines of inquiry so that the discipline of literary journalism may continue on its path of coalescence and achieve its potential. Para apoiar o jornalismo literário internacional como uma disciplina, e para que esta alcance todo o seu potencial, pode ser importante entender como o jornalismo literário está sendo ensinado. Como afirma John S. Bak, “a produção sólida de crítica, teoria e pedagogia eventualmente aglutinará o jornalismo literário que existe agora e criará o nicho da disciplina” (BAK, 2017, p. 236). Neste artigo, investigamos questões sobre o ensino do jornalismo literário de uma perspectiva ampla e específica. Em que países, universidades, departamentos e classes há o ensino do jornalismo literário e como ele está sendo ensinado? Quais métodos e textos são utilizados? Que desafios os educadores encontram e como eles estão sendo enfrentados? Estas são apenas algumas das questões que tentamos abordar aqui, investigando educadores on-line anualmente desde 2011 (com exceção do ano de 2013). O objetivo deste artigo é o de resumir um pouco do que aprendemos com tais pesquisas feitas na internet. Esperamos que os leitores digiram o que é oferecido aqui, façam perguntas, discutam com colegas e considerem futuras linhas de pesquisa para que a disciplina do jornalismo literário possa continuar em seu caminho de desenvolvimento e alcançar seu potencial.
