High-resolution electron microscopy of dislocation ribbons in a CMSX-4 superalloy single crystal

High-resolution scanning transmission electron microscopy (STEM) has been used to study the structure of dislocations in single crystal superalloy samples that have been subjected to conditions that favour the primary creep regime. The study has revealed the detailed structure of extended a2〈112〉 dislocations as they shear the γ′ precipitates during creep. These dislocations dissociate in a manner that is consistent with predictions made using the phase-field model of dislocations and also suggests the importance of the reordering process during their movement. The shearing done by the a〈1 1 2〉 dislocations was also found to distort the γ/γ′ interface, changing its appearance from linear to a "saw tooth" pattern. Another important observation was the segregation of alloying elements with a high atomic mass to the stacking faults, presumably to reduce their energies during shear. Numerous a2〈110〉 dissociated dislocations were also observed in the γ channels of the superalloy. The high resolution provided by the STEM imaging enables one to study the high-energy faults that are usually difficult to observe in conventional weak-beam TEM, such as complex intrinsic and extrinsic stacking faults in the γ′ and intrinsic stacking faults in the γ, and to make estimates of their energies

Unsteady stagnation-point heat transfer during passage of a concentrated vortex

The unsteady boundary layer due to a single rectilinear vortex filament approaching a 2-D stagnation point is investigated. Assuming the vortex remains far from the surface, incompressible potential flow theory is used to determine the time dependent inviscid flow field. The unsteady boundary layer equations are solved by an alternating-direction-implicit finite-difference method. Two mechanisms which cause fluctuations in heat transfer are the unsteady velocity field in the boundary layer and secondly, the unsteady total temperature at the edge of the boundary layer. The relative importance of these mechanisms is dependent upon the total temperature fluctuations relative to the imposed temperature difference. As a vortex approaches a stagnation point it may be forced to one side of the stagnation line or the other, depending on its initial position. Results are presented for both of these cases

Inclusion and education in European countries

The focus in this report is strategies that address the disadvantages experienced byminority background students in schools within the United Kingdom (UK) and the wider policy context in which these operate. More specifically, the focus is on four groups ofstudents:• Ethnic minority students including refugee and asylum seekers' children;• Gypsy/traveller students;• Students in care (Looked After Children - LAC); and,• Linguistic minorities e.g. Gaelic, Welsh.The devolved nature of government in the UK means that while some broad principlesare common across the four nations that constitute the UK (England, Northern Ireland,Scotland and Wales), the particular emphases adopted and the strategies developed tofoster social inclusion vary from one to another. In addition, there is no integrated policyfor social inclusion but rather separate policy statements for each of the categories ofdisadvantage identified in the study. All four countries within the UK have a combinationof private and state-funded schooling. In much, if not all, of this report the emphasis ison the state-funded sector

Emerald does not grant permission for this article to be further copied/distributed or hosted elsewhere without the express permission from Emerald Group Publishing Limited.This article was chosen as a Highly Commended Award Winner at the Emerald Literati Network Awards for Excellence 2013.Purpose – The paper aims to report on an exploratory study into how small businesses use Web 2.0 information and communication technologies (ICT) to work collaboratively with other small businesses. The study had two aims: to investigate the benefits available from the use of Web 2.0 in small business collaborations, and to characterize the different types of such online collaborations. Design/methodology/approach – The research uses a qualitative case study methodology based on semi-structured interviews with the owner-managers of 12 UK-based small companies in the business services sector who are early adopters of Web 2.0 technologies. Findings – Benefits from the use of Web 2.0 are categorized as lifestyle benefits, internal operational efficiency, enhanced capability, external communications and enhanced service offerings. A 2×2 framework is developed to categorize small business collaborations using the dimensions of the basis for inter-organizational collaboration (control vs cooperation) and the level of Web 2.0 ICT use (simple vs sophisticated). Research limitations/implications – A small number of firms of similar size, sector and location were studied, which limits generalizability. Nonetheless, the results offer a pointer to the likely future use of Web 2.0 tools by other small businesses. Practical implications – The research provides evidence of the attraction and potential of Web 2.0 for collaborations between small businesses. Originality/value – The paper is one of the first to report on use of Web 2.0 ICT in collaborative working between small businesses. It will be of interest to those seeking a better understanding of the potential of Web 2.0 in the small business community.WestFocu

Targeted Intracellular Therapeutic Delivery Using Liposomes Formulated with Multifunctional FAST proteins

Prostate cancer is the most common malignancy in North American men and there is no treatment currently available which offers a clear survival advantage to patients with prostate cancer. We studied liposomes formulated with the fusion-associated small transmembrane (FAST) protein, p14. In this study, we hypothesized that therapeutics delivered in molecular targeted fusogenic liposomes will increase intracellular delivery and specificity for prostate cancer. We demonstrated that liposomes formulated with p14-bombesin significantly increased the delivery of fluorescein isothiocyanate (FITC) into human prostate cancer (PC-3) cells compared to either standard liposomes or non-targeted fusogenic liposomes. Delivery of FITC to benign prostate hyperplasia (BPH) cells, which express low levels of the gastrin releasing peptide receptor (GRPR), was similar for targeted and non-targeted formulations. Specificity for GRPR was further established by knocking down GRPR expression with siRNA. Knockdown of the receptor resulted in equivalent intracellular delivery of the FITC with targeted and non-targeted formulations

Impact of nutrition education on dietary habits of female high school students

The objective of this study was to explore the impact of nutrition education on the nutritional intake of female high school students. Two groups of females from Saline High School (Saline, Michigan) participated in the study. Age, height, weight, and activity level were obtained from each student in the control group (N=5) and the experimental group (N=17). Participants also completed a demographic survey and a 3-day food diary (two weekdays and one weekend day). No significant differences were found between the groups in age, weight, height, or Body Mass Index (BMI). Diet analysis of the three-day food diaries showed significant differences (p\u3c0.05) in intake of dietary fiber and several vitamins and minerals. In this study it was found that students who took a nutrition education (NE) class consumed significantly more dietary fiber as well as certain vitamins and minerals. Amounts of these nutrients consumed by the NE group were closer to the Dietary Reference Intake (DRI)
