A partir do texto de Filipenses 2,5-11 este trabalho realiza uma exegese no texto conhecido como kenosis. Para isso, busca a identificação de traços existentes na herança ideológica da sociedade da época da redação deste documento para, em seguida, apontar para as possibilidades de estruturas míticas recorrentes. Faz uma primeira análise no mundo cultural, social e religioso do apóstolo Paulo e passa por uma breve abordagem da história da pesquisa. Oferece uma possibilidade de tradução do texto grego para o português e depois, quer visualizar em forma gráfica a estrutura e o movimento do hino cristológico . Apresenta o monomito e a análise do discurso como ferramentas metodológicas para a produção de duas novas leituras. Com o uso dessas metodologias, procura mostrar as semelhanças entre certas estruturas míticas recorrentes e o esvaziamento de Cristo na tradição paulina. Busca validar a proposta apresentando outras narrativas míticas que impregnavam a imagética da sociedade greco-romana. Ao final sugere alguns passos para uma leitura da kenosis como crítica social.

"El acceso abierto, al agilizar la comunicación científica, representa mayores posibilidades de apropiación y retorno a la sociedad de los resultados de investigación, fomenta el trabajo en red, e incrementa la disponibilidad de la producción académica y por consiguiente la visibilidad de las investigaciones realizadas en la Universidad. Además de fomentar el aumento de la productividad y de la accesibilidad propios del ejercicio investigativo, el acceso abierto puede igualmente potenciar las oportunidades de citaciones y de impacto de las publicaciones, lo cual repercuta en el crecimiento del posicionamiento institucional. Por estas razones, la Universidad del Rosario establece la política sobre el acceso abierto a la producción científica, académica e institucional y promueve los principios de este ante su comunidad."

Raman spectra were recorded in the range 400–1800 cm−1 for a series of 15 mixed \[tetrakis(4-tert-butylphenyl)porphyrinato](2,3-naphthalocyaninato) rare earth double-deckers M(TBPP)(Nc) (M = Y; La–Lu except Pm) using laser excitation at 632.8 and 785 nm. Comparisons with bis(naphthalocyaninato) rare earth counterparts reveal that the vibrations of the metallonaphthalocyanine M(Nc) fragment dominate the Raman features of M(TBPP)(Nc). When excited with radiation of 632.8 nm, the most intense vibration appears at about 1595 cm−1, due to the naphthalene stretching. These complexes exhibit the marker Raman band for Nc•− as a medium-intense band in the range 1496–1507 cm−1, attributed to the coupling of pyrrole and aza stretching, while the marker Raman band of Nc2− in intermediate-valence Ce(TBPP)(Nc) appears as a strong band at 1493 cm−1 and is due to the isoindole stretchings. By contrast, when excited with radiation of 785 nm that is in close resonance with the main Q absorption band of the naphthalocyanine ligand, the ring radial vibrations at ca 680 and 735 cm−1 for MIII(TBPP)(Nc) are selectively intensified and are the most intense bands. For the cerium double-decker, the most intense vibration also acting as the marker Raman band of Nc2− appears at 1497 cm−1 with contributions from both pyrrole CC and aza CN stretches. The same vibrational modes show weak to medium intensity scattering at 1506–1509 cm−1 for MIII(TBPP)(Nc) and this is the marker Raman band of Nc•− when thus excited. The scatterings due to the Nc breathings, ring radial vibration, aza group stretchings, naphthalene stretchings, benzoisoindole stretchings and the coupling of pyrrole CC and aza CN stretchings in MIII(TBPP)(Nc) are all slightly blue shifted along with the decrease in rare earth ionic radius, confirming the effects of increased ring–ring interactions on the Raman characteristics of naphthalocyanine in the mixed ring double-deckers.

As part of a large study investigating indoor air in residential houses in Brisbane, Australia, the purpose of this work was to quantify indoor exposure to submicrometer particles and PM2.5 for the inhabitants of 14 houses. Particle concentrations were measured simultaneously for more than 48 hours in the kitchens of all the houses by using a condensation particle counter (CPC) and a photometer (DustTrak). The occupants of the houses were asked to fill in a diary, noting the time and duration of any activity occurring throughout the house during measurement, as well as their presence or absence from home. From the time series concentration data and the information about indoor activities, exposure to the inhabitants of the houses was calculated for the entire time they spent at home as well as during indoor activities resulting in particle generation. The results show that the highest median concentration level occurred during cooking periods for both particle number concentration (47.5´103 particles cm-3) and PM2.5 concentration (13.4 mg m-3). The highest residential exposure period was the sleeping period for both particle number exposure (31%) and PM2.5 exposure (45.6%). The percentage of the average residential particle exposure level in total 24h particle exposure level was approximating 70% for both particle number and PM2.5 exposure.

In the title compound, C8H12NO+ C7H3N2O6-, the anilinium and hydroxyl protons of the cation result in N-H...O, N-H..(O,O) and O-H...O hydrogen-bonding interactions with carboxylate O atom acceptors, forming a two-dimensional network structure. An intermolecular C-H...O interaction is also present.
