The effect of silica nanoparticles and carbon nanotubes on the toughness of a thermosetting epoxy polymer
Authors: Hsieh T. H. , Kinloch A. J. , Taylor A. C. , Sprenger S. 
Published: August 2010

AbstractSilica nanoparticles and multiwalled carbon nanotubes (MWCNTs) have been incorporated into an anhydride‐cured epoxy resin to form “hybrid” nanocomposites. A good dispersion of the silica nanoparticles was found to occur, even at relatively high concentrations of the nanoparticles. However, in contrast, the MWCNTs were not so well dispersed but relatively agglomerated. The glass transition temperature of the epoxy polymer was 145°C and was not significantly affected by the addition of the silica nanoparticles or the MWCNTs. The Young's modulus was increased by the addition of the silica nanoparticles, but the addition of up to 0.18 wt % MWCNTs had no further significant effect. The addition of both MWCNTs and silica nanoparticles led to a significant improvement in the fracture toughness of these polymeric nanocomposites. For example, the fracture toughness was increased from 0.69 MPam1/2 for the unmodified epoxy polymer to 1.03 MPam1/2 for the hybrid nanocomposite containing both 0.18 wt % MWCNTs and 6.0 wt % silica nanoparticles; the fracture energy was also increased from 133 to 204 J/m2. The mechanisms responsible for the enhancements in the measured toughness were identified by observing the fracture surfaces using field‐emission gun scanning electron microscopy. © 2010 Wiley Periodicals, Inc.

Perception of a cetacean mass stranding in Italy: the emergence of compassion
Authors: Bearzi Giovanni , Pierantonio Nino , Bonizzoni Silvia , Notarbartolo di Sciara Giuseppe , Demma Massimo 
Published: August 2010

AbstractThe view that whales are malicious monsters has been pervasive throughout history. Conversely, the idea that these animals experience suffering has emerged only recently. One way of investigating perceptual, as well as behavioural, shifts is assessing general public reactions to mortality events involving wild, rare and charismatic animals.Here, the responses of 118 individuals to questions regarding the mass stranding of seven sperm whales (Physeter macrocephalus) along the Adriatic Sea coast of Italy in December 2009 are reported through interviews taken at the stranding site and in the direct proximity of the dead animals.When asked why the whales were stranded, 44.1% of the respondents suggested anthropogenic causes and 21.2% non‐anthropogenic. The remaining 34.7% mentioned a generic ‘disorientation’ or stated they did not know. When asked how they felt about the whales, 68.6% expressed feelings of compassion or care towards the animals. Clearly non‐compassionate attitudes accounted for only 4.1% of the sample. Finally, 21.2% expressed feelings that were ambiguous in terms of being suggestive of compassionate or non‐compassionate attitudes, including 11.9% amazement, 4.2% deprecation and 5.1% powerlessness.These results are in stark contrast with information obtained from accounts of similar events that have occurred in historical times, up until the first half of the 20th century. For centuries, responses to cetacean live strandings—typically including killing and harming of the animals—were either utilitarian or characterized by feelings including fear and a desire to ‘subjugate the beast’, with no apparent concern for their suffering and death.It is concluded that attitudes towards whales—today strikingly revolving around sadness, compassion and a sense of loss—have changed dramatically over time, with a steep turnaround in the 1970/1980s. Full appreciation of the ongoing evolution in public perception can channel marine conservation efforts and assist in the design of response strategies to marine mammal strandings.

Requirements and use of in‐service information in an engineering redesign task: Case studies from the aerospace industry
Authors: Jagtap Santosh , Johnson Aylmer 
Published: September 2010

AbstractThis article describes the research stimulated by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defense purposes, away from the selling of products to the provision of services. This research was undertaken in an aerospace company, which designs and manufactures aero engines and also offers contracts, under which it remains responsible for the maintenance of engines. These contracts allow the company to collect far more data about the in‐service performance of their engines than was previously available. This article aims at identifying what parts of this in‐service information are required when components or systems of existing engines need to be redesigned because they have not performed as expected in service. In addition, this article aims at understanding how designers use this in‐service information in a redesign task. In an attempt to address these aims, we analyzed five case studies involving redesign of components or systems of an existing engine. The findings show that the in‐service information accessed by the designers mainly contains the undesired physical actions (e.g., deterioration mechanisms, deterioration effects, etc.) and the causal chains of these undesired physical actions. We identified a pattern in the designers' actions regarding the use of these causal chains. The designers have generated several solutions that utilize these causal chains seen in the in‐service information. The findings provide a sound basis for developing tools and methods to support designers in effectively satisfying their in‐service information requirements in a redesign task.
A new C‐peptide correction model used to assess bioavailability of regular human insulin
Authors: Marino M. T. , Cassidy J. P. , Baughman R. A. , Boss A. H. , Richardson P. C. 
Published: September 2010

AbstractThe clinical assessment of new formulations of human insulin is problematic due to the inability to distinguish between endogenous insulin and exogenously administered insulin. The usual methods to surmount the problem of distinguishing between endogenous and exogenous human insulin include evaluation in subjects with no or little endogenous insulin, hyper‐insulinemic clamp studies or the administration of somatostatin to suppress endogenous insulin secretion. All of these methods have significant drawbacks. This paper describes a method for C‐Peptide correction based upon a mixed effects linear regression of multiple time point sampling of C‐Peptide and insulin. This model was able to describe each individual's insulin to C‐Peptide relationship using the data from four different phase I clinical trials involving both subjects with and without type 2 diabetes in which insulin and C‐Peptide were measured. These studies used hyper‐insulinemic euglycemic clamps or meal challenges and subjects received insulin or Glucagon‐like peptide 1 (GLP‐1). It was possible to determine the exogenously administered insulin concentration from the measured total insulin concentration. A simple statistical technique can be used to determine each individual's insulin to C‐Peptide relationship to estimate exogenous and endogenous insulin following the administration of regular human insulin. This technique will simplify the assessment of new formulations of human insulin. Copyright © 2010 John Wiley & Sons, Ltd.
Intraoperative ultrasonographic detection of communicating veins between adjacent hepatic veins during hepatectomy for tumours at the hepatocaval confluence
Authors: Torzilli G , Garancini M , Donadon M , Cimino M , Procopio F , Montorsi M 
Published: August 2010

Abstract

Background
The presence of communicating veins between adjacent hepatic veins may allow parenchyma-sparing hepatectomy. Taking advantage of improvements in ultrasound technology, such as e-flow modality, a study of the presence of communicating veins was conducted in patients with hepatic tumours at the caval confluence.

Methods
Consecutive patients undergoing surgery between October 2007 and December 2009 for hepatic tumours in contact with or invading a hepatic vein at its caval confluence were included. Communicating vein mapping by means of e-flow intraoperative ultrasonography (EF-IOUS) was carried out.

Results
A total of 20 patients were enrolled. Communicating veins between adjacent hepatic veins or with the inferior vena cava were detected in 16 patients. The median number of communicating veins was 1 (range 0–5). The total number of lesions removed was 126 (range 1–46). In 11 of 12 patients requiring resection of a hepatic vein, communicating veins enabled a parenchyma-sparing procedure to be performed. No patient had a formal major hepatectomy. There was no postoperative mortality or major morbidity.

Conclusion
EF-IOUS estimation of the frequency of communicating veins between adjacent hepatic veins suggests that such veins are common. This may facilitate parenchyma-sparing procedures in patients with hepatic tumours encroaching on major hepatic veins.
Randomized clinical trial comparing inflammatory and angiogenic response after open versus laparoscopic curative resection for colonic cancer
Authors: Pascual M , Alonso S , Parés D , Courtier R , Gil M J , Grande L , Pera M 
Published: August 2010

Abstract

Background
Several studies have suggested that laparoscopy might confer an oncological advantage in patients undergoing surgery for colonic cancer. A decreased inflammatory and angiogenic response has been proposed. This study compared the local and systemic inflammatory and angiogenic responses after open and laparoscopic surgery for colonic cancer.

Methods
Some 122 patients with colonic cancer were randomized to open or laparoscopic colectomy. Levels of interleukin (IL) 6 and vascular endothelial growth factor (VEGF) were measured in serum and peritoneal fluid at baseline, then at 4, 12, 24 and 48 h and on day 4 after surgery. Samples obtained on day 4 were tested in an in vitro angiogenesis assay, with measurement of number of capillaries per field and capillary length.

Results
The serum IL-6 level was lower in the laparoscopic group at 4 h (mean(s.d.) 124(110) versus 244(326) pg/dl after open colectomy; P = 0·027). The serum VEGF concentration was also lower in the laparoscopic group at 48 h and day 4 (430(435) versus 650(686) pg/dl; P = 0·001). Overall, local IL-6 and VEGF levels were significantly higher than serum levels but there were no differences between groups. In vitro, postoperative serum and peritoneal fluid samples were potently angiogenic but there were no differences between open surgery and laparoscopy. Rates of tumour recurrence and survival were similar in the two groups.

Conclusion
Despite differences in postoperative serum levels of IL-6 and VEGF after open and laparoscopic surgery in patients with colonic cancer, the angiogenic response is comparable in both surgical approaches. Registration number: ISRCTN55624793 (http://www.controlled-trials.com).
Managing contact in Scotland for children in non‐permanent out‐of‐home placement
Authors: Sen Robin 
Published: August 2010

AbstractThere has been little research on social workers' views and experiences of managing contact for children in public care, and none focused in Scotland, where different institutional and legal features provide contrast with the rest of the UK. This study explored the views of 19 social work practitioners and managers and three Reporters to the Children's Hearing system regarding the management of contact for children in non‐permanent placements, using semi‐structured interviews and a focus group. The paper focuses on the themes of the supervision and assessment of contact, risks associated with contact and contact via ICT—e‐mail and the internet. It suggests improvements in assessing contact are needed and concludes that while there are strengths in practitioners' current awareness of risks, a risk‐based conception of contact, as exemplified by most respondents' views about the use of new technology, is in tension with the thrust of current legislation; conceptions of contact need to be flexible enough to embrace the variety of purposes contact might serve.

Sexithiophene Encapsulated in a Single‐Walled Carbon Nanotube: An In Situ Raman Spectroelectrochemical Study of a Peapod Structure
Authors: Kalbáč Martin , Kavan Ladislav , Gorantla Sandeep , Gemming Thomas , Dunsch Lothar 
Published: August 2010

AbstractThe interaction of single‐walled carbon nanotubes (SWCNTs) and α‐sexithiophene (6T) was studied by Raman spectroscopy and by in situ Raman spectroelectrochemistry. The encapsulation of 6T in SWCNT and its interaction causes a bleaching of its photoluminescence, and also small shifts of its Raman bands. The Raman features of the SWCNT with embedded 6T (6T‐peapods) change in both intensity and frequency compared to those of pristine SWCNT, which is a consequence of a change of the resonant condition. Electrochemical doping demonstrated that the electrode potential applied to the SWCNT wall causes changes in the embedded 6T. The effects of electrochemical charging on the Raman features of pristine SWCNT and 6T@SWCNT were compared. It is shown that the interaction of SWCNT with 6T also changes the electronic structure of SWCNT in its charged state. This change of electronic structure is demonstrated both for semiconducting and metallic tubes.
