Preparation and properties of poly(imide siloxane) segmented copolymer/silica hybrid nanocomposites
Authors: Liaw Wen‐Chang , Chen Kuan‐Pin
Published: April 2007

A series of Poly(imide siloxane) (PIS)/silica (SiO2) hybrid nanocomposites with C‐Si covalent bonding between the homogeneous PIS copolymer and SiO2 have been successfully synthesized. The PIS copolymer synthesized in this study is characterized by the coexistence of two segments: the polyimide segment and polydimethyldiphenylsiloxane segment, and the latter are specially featured with the introduction of a diphenyl group for improved homogeneity. The PIS/SiO2 hybrid nanocomposites were prepared from 3,3′,4,4′‐bezonphenone tetracarboxylic dianhydride (BTDA), 2‐2′‐bis[4(3‐aminophenoxy)phenyl] sulfone (m‐BAPS), and vinyl‐containing α,ω‐bis‐(aminopropyl)polydimethyldiphenyl siloxane (APPPVS) oligomer to form vinyl siloxane‐containing poly(amic acid) (PAAVS). This copolymer was further reacted with trimethoxyvinylsilane (TMVS), 2,2′‐azobis‐isobutyronitrile (AIBN), and tetraethoxysilane (TEOS). The PIS/SiO2 hybrid nanocomposites exhibited a series of properties unlike traditional composites, and the nano sized inorganic particles have resulted in a transparent hybrid when the SiO2 content was less than 12 wt %. The Young's modulus and tensile strength of the PIS/SiO2 hybrid nanocomposites increased with increasing SiO2 content, whereas, the elongation at break was only slightly affected. The structure of the hybrids was characterized by FTIR, 29Si‐NMR, 1H‐NMR, and 13C‐NMR, as well as SEM and TEM. The thermal properties of the PIS/SiO2 hybrid nanocomposites were investigated with DSC, TGA, and DMA studies. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Characterizing the marine Natura 2000 network for the Atlantic region
Authors: Johnson M.P. , Crowe T.P. , McAllen R. , Allcock A.L.
Published: April 2007

One of the goals for Natura 2000, a key European Community programme of nature conservation, is to produce a network of protected areas. An analysis of the Natura 2000 marine sites proposed in the most recently agreed list for the Atlantic region (northern Portugal to Denmark, n=298) was used to characterize the network in terms of site areas and inter‐site distances. Sites were considered as part of the network when they included any of the marine Natura 2000 Annex I habitat types found in the Atlantic region (excluding lagoons).

The median size of individual sites was 7.6 km2 with a median separation among neighbouring sites of 21 km (range 2–138 km).

A connectivity analysis was used to identify the potential reliance of species on areas of habitat outside the proposed network. This analysis was based on the assumptions that: (a) species with low dispersal capacity will persist in sites when local reproductive effort sustains the resident population and (b) greater dispersal scale will link sites in the network, but implies a greater loss of recruits from the local population. For intermediate dispersal scales (2–20 km), at least half of the proposed sites are likely to be both too small and too isolated to support populations in the network. The conservation of intermediate dispersers in such sites may therefore be more dependent on habitat outside the network than is the case for other dispersal capabilities. Species with both dispersal scales above 20 km and low habitat specificity may have a metapopulation structure with exchange of dispersing individuals occurring among protected sites. Species with increasing degrees of habitat specificity will need dispersal scales greater than 20 km to avoid dependence on areas outside the proposed network.

Most sections of the Atlantic region coastline contain proposed Nature 2000 sites. An analysis of site area and average isolation at the 1° latitude by 1° longitude scale indicated that relatively well designated sections (in terms of area and site spacing) of the coast were interspersed with less well designated sections. Analyses of overall habitat availability and population genetic studies are required to assess the significance of varying levels of protection at this scale.

Web searching in Chinese: A study of a search engine in Hong Kong
Authors: Chau Michael , Fang Xiao , Yang Christopher C.
Published: April 2007

The number of non‐English resources has been increasing rapidly on the Web. Although many studies have been conducted on the query logs in search engines that are primarily English‐based (e.g., Excite and AltaVista), only a few of them have studied the information‐seeking behavior on the Web in non‐English languages. In this article, we report the analysis of the search‐query logs of a search engine that focused on Chinese. Three months of search‐query logs of Timway, a search engine based in Hong Kong, were collected and analyzed. Metrics on sessions, queries, search topics, and character usage are reported. N‐gram analysis also has been applied to perform character‐based analysis. Our analysis suggests that some characteristics identified in the search log, such as search topics and the mean number of queries per sessions, are similar to those in English search engines; however, other characteristics, such as the use of operators in query formulation, are significantly different. The analysis also shows that only a very small number of unique Chinese characters are used in search queries. We believe the findings from this study have provided some insights into further research in non‐English Web searching.
Role of annexin 1 gene expression in mouse craniofacial bone development
Authors: Damazo Amilcar Sabino , Moradi‐Bidhendi Niloufar , Oliani Sonia Maria , Flower Roderick John
Published: April 2007

BACKGROUND:

Annexin 1 is a 37‐kDa protein that has complex intra‐ and extracellular effects. To discover whether the absence of this protein alters bone development, we monitored this event in the annexin‐A1 null mice in comparison with littermate wild‐type controls.

METHODS:

Radiographic and densitometry methods were used for the assessment of bone in annexin‐A1 null mice at a gross level. We used whole‐skeleton staining, histological analysis, and Western blotting techniques to monitor changes at the tissue and cellular levels.

RESULTS:

There were no gross differences in the appendicular skeleton between the genotypes, but an anomalous development of the skull was observed in the annexin‐A1 null mice. This was characterized in the newborn annexin‐A1 null animals by a delayed intramembranous ossification of the skull, incomplete fusion of the interfrontal suture and palatine bone, and the presence of an abnormal suture structure. The annexin‐A1 gene was shown to be active in osteocytes during this phase and COX‐2 was abundantly expressed in cartilage and bone taken from annexin‐A1 null mice.

CONCLUSIONS:

Expression of the annexin‐A1 gene is important for the normal development of the skull in mice, possibly through the regulation of osteoblast differentiation and a secondary effect on the expression of components of the cPLA2‐COX‐2 system.

Characteristics of research on green marketing
Authors: Chamorro Antonio , Rubio Sergio , Miranda Francisco J.
Published: April 2007

This paper aims to describe and analyze the main characteristics of articles on green marketing published in the most relevant journals within the period 1993–2003, in order to determine the evolution of this current issue of research over recent years and improve our understanding of this subject. We built up a database with 112 articles on green marketing and we have explored the topic, the methodology and the techniques of analysis, as well as other relevant aspects of the research. In order to complete this analysis, we made a review of articles published in two journals specializing in environmental management: BSE and CSREM. In this way, this paper offers practical help to those who are beginning research on this topic because the results will help us to determine what still needs to be investigated in this topic and hence propose a research agenda for the coming years.

Characterization of Portland cements by X‐ray spectrometry allied to chemometrics
Authors: Goraieb Karen , Lopes Aline Soriano , Sato Cíntia Akemi , Segatelli Mariana Gava , Silva Viviane Pacheco e , Verzoto José Carlos , Bueno Maria Izabel Maretti Silveira
Published: April 2007

This work reports the use of X‐ray spectrometry (XRS) allied to chemometric techniques to easily distinguish types of Portland cements, as well as to quantify some of their constituent elements. The samples were irradiated as powders for 200 s using two distinct irradiation conditions, one more adequate for heavier elements (condition 1) and the other (condition 2) for lighter elements, using a conventional bench top energy dispersive X‐ray fluorescence (EDXRF) equipment. The spectra were processed via the software The Unscrambler, version 9.2. The PLS 1 LV1 × LV2 scores graph shows a classification into five groups, in accordance with the calcium concentration, using condition 2. The classification of the cements by producer was feasible using the PLS1 LV1 × LV3 scores graph, with condition 1. The elements Ca, Si, Al and Mg were successfully quantified using multivariate calibration of the whole spectra. However, for Fe, S and K, better results were obtained by correlating their corresponding Kαpeaks with concentrations in a univariate procedure, using irradiation condition 2.

Chemometric tools allied to XRS are powerful techniques to classify Portland cements, regarding to their origins and their calcium concentration, which is related to the cement type. The PLS chemometric tool was very useful to easily quantify light elements, such as Al, Si and Mg, a challenge in most X‐ray analytical methods, since their Kαemission peaks are very close to each other.

Authors: Krätz Otto
Published: April 2007

Es ist nicht einmal mehr eine Frage der Zeit, dass auch im Kino elektronische Datenträger den Celluloid‐ bzw. Acetylcellulosefilm für immer ersetzen werden.

Dynamic vertical compliance of strip foundations in layered soils
Authors: Israil A. S. M. , Ahmad S.
Published: April 2007

In this paper, results of a detailed investigation on the dynamic response of rigid strip foundations in viscoelastic soils under vertical excitation are presented. An advanced boundary element algorithm developed by incorporating isoparametric quadratic elements and a sophisticated self‐adapting numerical integration scheme has been used for this investigation. Foundations supported on three types of soil profiles, namely, homogeneous half‐space, stratum‐over‐half‐space and stratum‐over‐bedrock are considered. The influence of material properties like Poisson's ratio and material damping as well as the influence of geometrical properties such as depth of embedment and layer thickness are studied. The effect of the type of contact at the soil‐foundation interface is also investigated.
