NEAR INFRARED SPECTRUM OF
No full textAuthor Institution: Department of Physics and Astronomy, Michigan State CollegeThe first (2-0) and second (3-0) overtones of DCl have been obtained with high dispersion in the 2.4 and 1.6 regions. The dispersing system consisted of a recording vacuum spectrograph equipped with a 15,000-line-per-inch grating and a lead sulfide detector. Calibration was obtained by making use of the second order Argon emission lines and Fabry-Perot etalon fringes. Analysis yields molecular constants essentially in agreement with those obtained by Pickworth and for the fundamental. In addition the data yields values for the anharmonic constants. These values agree within experimental error with the calculated values as based on the data for HCl

THE INFRARED EMISSION SPECTRUM OF DCL
No full textAuthor Institution: Department of Chemistry, University of WaterlooThe vibrational rotational emission spectrum of DCl was recorded with a Fourier transform spectrometer; line positions for the 1-0, 2-1, 3-2 and 4-3 bands of and the 1-0, 2-1 and 3-2 bands of were measured. The two sets of data were combined with previously measured submillimeter were pure rotational transitions to obtain Dunham constants. A combined isotopomer analysis of data for all four isotopic forms of HCl was also performed combining these new data with analogous literature results for and , to yield Born-Oppenheimer breakdown correction terms for this system. The results of similar analyses of HF and HBr allowed a comparison of Born-Oppenheimer breakdown correction terms for HF, HCl and HBr
Contação de histórias para crianças
No full textTCC (graduação em Biblioteconomia) - Universidade Federal de Santa Catarina, FlorianópolisDiscorre sobre a contação de histórias realizada em duas Instituições de Florianópolis: a Livraria Catarinense e a Barca dos Livros. Ambas incentivam a leitura por meio da literatura infantil. O objetivo geral foi descrever a contação de histórias e, como objetivos específicos, observar as reações das crianças diante das histórias contadas, verificar quais as histórias mais contadas, verificar os métodos empregados na contação e observar se a contação de histórias desperta o gosto pela leitura. Para alcançar esses objetivos a acadêmica assistiu como observadora, as contações nos dois locais citados, no período de março a junho de 2011. Assim, a presente pesquisa é descritiva, bibliográfica e estudo de caso. A revisão de literatura contemplou as origens do conto, o conto infantil no Brasil, os célebres dos contos de fadas, a figura do contador de histórias e a importância das histórias infantis no imaginário das crianças. Por meio das observações in loco constatou que as atividades de #Hora do Conto# (nome dado ao momento de contação de histórias nos locais observados) têm efeito catártico nas crianças. Também foi observado, que muitas crianças se interessam em folhear os livros, se deliciam com as ilustrações, buscam conhecer novas histórias, prestam atenção às histórias do inicio ao fim e interagem com o contador. Conclui que a atividade de contação de histórias desperta o gosto pela leitura

Salvador, BA, Brasil / Instituto de Investigação em Imunologia. INCT. Salvador, BA, BrasilA Leishmaniose Cutânea Difusa (LCD) é uma manifestação clínica rara das leishmanioses, caracterizada pela
presença de inúmeros macrófagos intensamente parasitados. Tem sido sugerido que a LCD resulta da ausência de
resposta imune celular a antígenos de Leishmania, levando ao crescimento descontrolado do parasita. No Brasil, a
LCD é quase que exclusivamente causada pela Leishmania (Leishmania) amazonensis. Nessa revisão discutiremos o
papel da morte celular programada por apoptose como possível mecanismo imunopatogênico na infecção por L.
amazonensis. Semelhante ao que ocorre durante o reconhecimento e fagocitose de células apoptóticas, formas
amastigotas de L. amazonensis expõem PS em sua superfície, em um mecanismo chamado “Mimetismo Apoptótico”
que resulta na desativação do macrófago e possibilita o estabelecimento e manutenção da infecção. Nesse contexto,
o estudo da exposição de PS nos isolados de L. amazonensis de pacientes com LCD pode contribuir na elucidação de
mecanismos supressores nessa patologiaDiffuse Cutaneous Leishmaniasis (DCL) is a rare clinical manifestation of Leishmaniasis, characterized by a number of
macrophages heavily parasitized. It has been suggested that DCL results from a lack of cell-mediated immunity to leishmanial
antigen, leading to uncontrolled parasite growth. In Brazil, Leishmania (Leishmania) amazonensis is the main specie
involved in DCL cases. In this review we approached the role of programmed cell death by apoptosis as a possible
immunopathogenic mechanism in the L. amazonensis infection. Similarly to the exposure and recognition of apoptotic
cells, L. amazonensis amastigotes expose PS on its surface, in a mechanism called “Apoptotic Mimicry” which drives
macrophage deactivation and allows the infection establishment and maintenance. In this context, the study of PS
exposure in the isolates of L. amazonensis of patients with DCL may contribute in the elucidation of suppressor mechanisms
in this pathology

ANALYSIS OF AUTOIONIZING RYDBERG STATES IN THE VACUUM ULTRAVIOLET ABSORPTION SPECTRUM OF HCl AND DCl
No full textAuthor Institution: Department of Chemistry, Yale UniversityThe photographic absorption spectra of HCl and DCl have been analyzed above the 1st ionization potential ( \AA). Rydberg series converging to the 2nd ionization limit () have been identified with quantum defects of 1.8 and 2.2. No rotational structure was observed in either series, indicating that the autoionization rate is faster than the rotational period (about for the lowest members of the two series). The symmetries of the Rydberg states cannot be determined conclusively since the rotational fine structure is obscured. Photoelectric studies of the absorption spectrum are underway in order to determine the relative intensities and lineshapes of the individual transitions
Determinants of cross-country income inequality : an augmented Kuznets hypothesis
No full textWhy does income inequality differ among countries? Using a sample of 80 countries from the 1980s, the author shows that two types of factors explain variations in income inequality. The first are factors that are, in the short term, independent of economic policies and are included in the standard formulation of the Kuznets'curve: the level of per capita income and the country's regional heterogeneity. From the viewpoint of economic policy, these are"given"factors, resulting in a"given inequality."The second group of factors are the social-choice factors reflected in the sizeof social transfers and of state sector employment, both of which reduce inequality. For this sample, the reduction amounts to about a quarter of"given"inequality. The importance of social-choice factors rises as the level of income rises. The divergence between actual inequality and the inequality predicted by the standard Kuznets'curve therefore systematically widens as a society develops. This discrepancy is systematic, the author contends. Inequality in richer societies decreases not only because of economic factors but also because societies choose less inequalities as they grow richer.Inequality,Poverty Impact Evaluation,Environmental Economics&Policies,Services&Transfers to Poor,Safety Nets and Transfers
Estado nutricional del adulto mayor y su relación con el deterioro cognitivo leve y la demencia tipo alzheimer en La Habana
No full textEl envejecimiento es una etapa del ciclo vital con vulnerabilidad del estado nutricional, que a su vez puede estar condicionado por la presencia de enfermedades crónicas.Dentro de éstas, la enfermedad de Alzheimer (EA), está alcanzando proporciones epidémicas siendo causa de morbilidades, discapacidades y muertes. Con el objetivo de evaluar el estado nutricional y su relación con el Deterioro Cognitivo Leve (DCL) y la EA en un grupo de adultos mayores de La Habana, se realizó un primer estudio observacional de tipo descriptivo transversal y un segundo estudio analítico transversal en otro grupo de adultos mayores clasificados clínicamente según deterioro cognitivo. Se pudo determinar que el estado nutricional de los adultos mayores fue inadecuado, poniéndose en evidencia la carga dual de malnutrición, dada por la deficiencia de micronutrientes y el alto porcentaje de sobrepeso global. Además, la anemia, el hematocrito bajo, la hiperhomocisteinemia y la deficiencia de las vitaminas B2 y A se encontraban asociadas a una alta prevalencia de DCL, mientras que la anemia, el hematocrito bajo, la hiperhomocisteinemia y la deficiencia de las vitaminas: B1, B2, C, folato, B12 y A estaban asociadas a una alta prevalencia de la EA. Sin embargo, los altos niveles de colesterol-LDL y de colesterol-total fueron asociados a una baja prevalencia de DCL y de la EA. Por primera vez, en Cuba, se evaluó de manera integral el estado nutricional de un grupo de adultos mayores de La Habana y se demostró la relación existente entre algunos indicadores nutricionales con los trastornos cognitivos
