Templated synthesis of carbon materials mediated by porous clay heterostructures

Mesoporous carbon materials were prepared through template method approach using porous clay heterostructures (PCHs) as matrix and furfuryl alcohol as carbon precursor. Three PCHs prepared using amines with 8, 10 and 12 carbon atoms were used. The effect of several impregnation-polymerization cycles of the carbon precursor, the carbonization temperature and the need of a previous surface alumination were evaluated. The presence of two porosity domains was identified in all the carbon materials. These two domains comprise pores resulting from the carbonization of the polymer film formed in the inner structure of the PCH (domain I) and larger pores created by the clay particles aggregation (domain II). The predominance of the porosity associated to domain I or II can be achieved by choosing a specific amine to prepare the PCH matrix. Carbonization at 700 C led to the highest development of pores of domain I. In general, the second impregnation-polymerization cycle of furfuryl alcohol resulted in a small decrease of both types of porosity domains. Furthermore the previous acidification of the surface to create acidic sites proved to be unnecessary. The results showed the potential of PCHs as matrices to tailor the textural properties of carbons prepared by template mediated synthesis

Mitochondrial DNA variability in populations from East Timor (Timor Leste)

In this study we continue the genetic characterization of human populations from East Timor, as previously started for autosomal STRs and Y STRs, with a preliminary report on mitochondrial DNA (mtDNA) diversity. Individual samples (n = 133) collected from all the districts of East Timor and representing different linguistic groups were studied for the hypervariable region 1 (HVS1) sequence and the 9-bp deletion (intergenic region COII-tRNA lys).http://www.sciencedirect.com/science/article/B7581-4JSBXBX-1J/1/f4cc71eebbd2186e586bae7a77c79cc

Mineralização de C e de N na palhada de cana-de-açúcar.

Resumo: A biomassa vegetal que permanece em cima do solo após a colheita pode representar, em longo prazo incremento de matéria orgânica no solo e redução da necessidade de reposição de nutrientes via fertilizantes minerais. O objetivo dessa pesquisa foi avaliar a mineralização de C e de N em diferentes quantidades de palhada da cana-de-açúcar ao longo de um ciclo de cultivo. Os tratamentos avaliados correspondem aos níveis 25% - 50% - 75% e 100% (respectivamente 2,8 - 5,7 - 8,5 -11,3 t ha-1) de palhada remanescentes da colheita da cana-de-açúcar (variedade RB-845210), distribuídos em delineamento de blocos ao acaso, com quatro repetições. A avaliação da liberação de carbono e de nitrogênio foi realizada utilizando-se o método do "saco de serrapilheira" ("Litter bag"). Por meio dos resultados foi possível concluir que a dinâmica da mineralização do carbono na palha de cana-de-açúcar é influenciada pelo nível desta biomassa, embora ao final do ciclo as taxas de mineralização do C (70%) se tornem semelhantes para todos os níveis de palhada estudados. O nitrogênio inicialmente fica imobilizado na biomassa. Ao final do ciclo, em função da redução da relação C/N, este elemento começa a ser disponibilizado

Bioaccumulation of amylose-like glycans by Helicobacter pylori

Background: Helicobacter pylori cell surface is composed of lipopolysaccharides (LPSs) yielding structures homologous to mammalian Lewis O-chains blood group antigens. These structures are key mediators in the definition of host-microbial interactions and known to change their expression pattern in response to environmental pressure. Aims:  The present work is focused on the identification of new H. pylori cell-surface glycosides. Special attention is further devoted to provide insights on the impact of in vitro subcultivation on H. pylori cell-surface phenotypes. Methods:  Cell-surface glycans from H. pylori NCTC 11637 and two clinical isolates were recovered from the aqueous phase resulting from phenol:water extraction of intact bacteria. They were evaluated in relation to their sugars and glycosidic-linkages composition by CG-MS, size-exclusion chromatography, NMR, and Mass Spectrometry. H. pylori glycan profile was also monitored during subcultivation in vitro in agar and F12 liquid medium. Results:  All three studied strains produce LPS expressing Lewis epitopes and express bioaccumulate amylose-like glycans. Bioaccumulation of amylose was found to be enhanced with the subcultivation of the bacterium on agar medium and accompanied by a decrease in the expression of LPS O-chains. In contrast, during exponential growth in F12 liquid medium, an opposite behavior is observed, that is, there is an increase in the overall amount of LPS and decrease in amylose content. Conclusions:  This work shows that under specific environmental conditions, H. pylori expresses a phase-variable cell-surface α-(1→4)-glucose moiety

Using simulation to model the logistic operations of a company of the cement industry

This paper presents a discrete-event simulation model to study the logistics operations involved in a plant of the cement industry, aligned with a real project developed in partnership between Cachapuz (a company that provides international weighing solutions) and the University of Minho. The purpose of this work consists in using simulation to model several activities, involving weighing, loading and unloading of raw materials, regardless of the type of industry, e.g. cement, tomato, cereals. Thus, this paper documents the work conducted to apply the developed simulation model in a case study of the cement industry. After validating the model, a set of simulation experiments were conducted, which allowed to estimate the maximum capacity of the plant and the impact in the performance of the plant, of the arrival of a cargo vessel. In this regard, it was found that in the case study in question, it is not possible to unload all the cargo from the vessel in a working day - around 3 working days would be required. Further conclusions and future work are discussed in the last section.- (undefined
