Bacillus subtilis Phages Related to SIOphi from Desert Soils of the Southwest United States
No full textBackground: Phages impact Bacillus subtilis microbial dynamics, but our understanding of the diversity of phages that can lyse this model organism is limited. Materials and Methods: Phages were isolated from soil collected from two Southwest United States desert sites on wild B. subtilis strains. Phage genomes were assembled and bioinformatically characterized, and phage host range was assessed. Results: Four myoviruses with high nucleotide and amino acid similarity to each other (\u3e97%) and to three phages in GenBank (\u3e82%), including SIOphi, were isolated. These phages have double-stranded DNA genomes (153,882–156,577 bp), low GC content, and 256–270 putative protein coding genes (28–30% with predicted functions). Comparative genomics revealed differences in putative lysis and replication genes. Conclusions: Comparative approaches provide insight into phage evolution, identifying unique genes shared within phage clusters. Better characterization of Bacillus phages will aid in linking genetic differences among phages (e.g., lysin genes) to phenotype (e.g., host range)
“A quem o quizer colher”: as drogas do sertão e o Diretório dos Índios, Grão-Pará, 1757-1798
No full textO clima quente, a abundância de terra e água e a vegetação exuberante da vasta bacia do rio Amazonas impressionaram os europeus com uma cornucópia de alimentos, especiarias, fibras, óleos e madeira. Por volta de 1611, ingleses, irlandeses e, depois, holandeses e franceses, negociavam, com os povos nativos do baixo Amazonas, madeiras e urucum, pigmento corporal vermelho-alaranjado que se vendia na Europa como produto tintório, e iniciavam plantações de tabaco e algodão. Enriquecidos pelo comércio asiático de especiarias e tinturas, os portugueses, agora ameaçados por outras nações europeias, se deslocaram para o norte do Brasil e começaram a ocupar a Amazônia, a partir de 1616, onde procuraram avidamente substitutos para os gêneros asiáticos, drogas como o cravo, a casca de uma árvore com cheiro e sabor semelhantes ao cravo da Índia. Baseado nas tradições asiática, portuguesa, espanhola e indígena, um conjunto amplo de produtos, especialmente cravo, salsaparrilha e, sobretudo, cacau, logo se tornou a base da economia de exportação portuguesa regional, junto com outros produtos da floresta – as drogas do sertão.

Teacher Inquiry: A Catalyst for Professional Development
No full textTeachers seek and require meaningful professional development opportunities to truly grow in the profession. Teacher inquiry, or teacher research, is one way to accomplish professional development goals. Teacher inquiry is thought of as individualized, personalized, and meaningful professional development (Cochran-Smith & Lytle, 1999). In this paper we articulate the learning of a cohort of certificated professionals engaged in a year-long project that included asking research questions, designing data collection tools, and developing an independent study to examine their questions. Nine certificated professionals participated in the year-long project representing various grade levels and experiences. Data was collected through teacher reflections and professional development evaluations. The findings indicated that a trusting, supportive environment is paramount in developing a culture of inquiry. Further learning shows us that peer collaboration promotes professional growth when exploring individual projects. This paper furnishes further evidence of the importance of teaching inquiry in schools and provides a sample structure for schools wishing to develop a practice of teacher inquiry

Inequality of Air Quality?: A Study of Air Quality within Housing Price Brackets in Gettysburg, PA
Get PDFWith the rise of cars and other motorized vehicles has come the rise of air pollution, which tends to have disproportionate environmental and health impacts on low-income and communities of color. This study analyzes car presence and air quality on a transect within Gettysburg, PA to determine if there is a relationship between air pollution and vehicle presence, and if there is a difference in air quality between higher price bracket housing compared to campus, commercial, and lower price bracket housing. To test our research questions, we identified nine sampling locations along a transect where we measured air pollutants, including particulate matter (2.5 um and 10 um), VOCs, and NO2, with Flow by Plume Labs and Atmotube Pro air quality monitors. Our hypotheses that car activity will increase the amount of air pollution in Gettysburg and that there will be a greater environmental justice disparity within lower housing price brackets were not supported. The air quality along the transect was not greatly affected by vehicle presence and was consistent with regional conditions, and while measurements of different pollutants changed with location, there was not one clear trend between these two variables. However, there were consistently higher levels of vehicle traffic in the commercial and low-income areas than in the high-income and campus areas. The main limitations of our study were the lack of functionality and accuracy of our air monitors, which reduced the sample size of our data. These results provide room for further study of racial and child health disparities caused by cars and air pollution, as well as the impact of higher traffic levels on the risk of car and pedestrian accidents
