Application of Atomic Force Microscopy in Formulation Engineering

Atomic force microscopy (AFM) an analytical technique based on probing a surface or interface with a microcantilever, has become widely used in formulation engineering applications such as consumer goods, food and pharmaceutical products. Its application is not limited to imaging surface topography with nanometre spatial resolution, but is also useful for analysing material properties such as adhesion, hardness and surface chemistry. AFM offers unparalleled advantages over other microscopy techniques when studying colloidal systems. The minimum sample preparation requirements, in situ observation and flexible operational conditions enable it to act as a versatile platform for surface analysis. In this review we will present some applications of AFM, and discuss how it has developed into a repertoire of techniques for analysing formulated products at the nanoscale under native conditions

Females do not have more injury road accidents on Friday the 13th

BACKGROUND: This study reinvestigated the recent finding that females – but not males – die in traffic accidents on Friday the 13th more often than on other Fridays (Näyhä S: Traffic deaths and superstition on Friday the 13th. Am J Psychiatry 2002, 159: 2110–2111). The current study used matched setting and injury accident data base that is more numerous than fatality data. If such an effect would be caused by impaired psychic and psychomotor functioning due to more frequent anxiety among women, it should also appear in injury crashes. METHODS: We used the national Finnish road accident database for 1989–2002. To control seasonal variation, 21 Fridays the 13th were compared in a matched design to previous and following Fridays, excluding all holidays, on number of accidents, male/female responsibility for accidents, and the number of dead, injured and overall number of active participants (drivers, pedestrians and bicyclists) as a consequence of the accident. RESULTS: There were no significant differences in any examined aspect of road injury accidents among the three Fridays, either in females or males. Women were not overrepresented in crashes that occurred on Fridays 13th. CONCLUSION: There is no consistent evidence for females having more road traffic crashes on Fridays the 13th, based on deaths or road accident statistics. However, this does not imply a non-existent effect of superstition related anxiety on accident risk as no exposure-to-risk data are available. People who are anxious of "Black Friday" may stay home, or at least avoid driving a car

The different roles of ‘design process champions’ for digital libraries in African higher education

The concept of design stakeholders is central to effective design of digital libraries. We report on research findings that identified the presence of a key subset of stakeholders which we term ‘design process champions’. Our findings have identified that these champions can change interaction patterns and the eventual output of the other stakeholders (project participants) in the design process of digital library projects. This empirical research is based upon 38 interviews with key stakeholders and a review of documentary evidence in ten innovative digital library design projects (e.g. mobile clinical libraries) located in three African universities in Kenya, Uganda and South Africa. Through a grounded theory approach two different types of the ‘design process champions’ emerged from the data with varying levels of effectiveness in the design process: (i) domain champions and (ii) multidisciplinary champions. The domain champions assume a ‘siloed’ approach of engagement while the multidisciplinary champions take on a participatory engagement throughout the design process. A discussion of the implications of information specialists functioning as domain champions is highlighted. We conclude by suggesting that the multidisciplinary champions’ approach is particularly useful in supporting sustainability of digital library design projects

Tephrochronology

Tephrochronology is the use of primary, characterized tephras or cryptotephras as chronostratigraphic marker beds to connect and synchronize geological, paleoenvironmental, or archaeological sequences or events, or soils/paleosols, and, uniquely, to transfer relative or numerical ages or dates to them using stratigraphic and age information together with mineralogical and geochemical compositional data, especially from individual glass-shard analyses, obtained for the tephra/cryptotephra deposits. To function as an age-equivalent correlation and chronostratigraphic dating tool, tephrochronology may be undertaken in three steps: (i) mapping and describing tephras and determining their stratigraphic relationships, (ii) characterizing tephras or cryptotephras in the laboratory, and (iii) dating them using a wide range of geochronological methods. Tephrochronology is also an important tool in volcanology, informing studies on volcanic petrology, volcano eruption histories and hazards, and volcano-climate forcing. Although limitations and challenges remain, multidisciplinary applications of tephrochronology continue to grow markedly

Diabetes Health, Residence & Metabolism in Asians: the DHRMA study, research into foods from the Indian subcontinent - a blinded, randomised, placebo controlled trial

<p>Abstract</p> <p>Background</p> <p>Coronary heart disease (CHD) is highly prevalent amongst the South Asian communities in Britain. The reasons for this excess CHD risk are multifactorial, but in part relate to a susceptibility to diabetes mellitus - where the aberrant metabolism of non-esterified fatty acids (NEFA) and glucose are likely to underpin vascular disease in this population. Dietary intervention is an important and first line approach to manage increased CHD risk. However, there is limited information on the impact of the South Asian diet on CHD risk.</p> <p>Methods/Design</p> <p>The Diabetes Health, Residence & Metabolism in Asians (DHRMA) study is a blinded, randomised, placebo controlled trial that analyses the efficacy of reduced glycaemic index (GI) staples of the South Asian diet, in relation to cardio-metabolic risk factors that are commonly perturbed amongst South Asian populations - primarily glucose, fatty acid and lipoprotein metabolism and central adiposity. Using a 10-week dietary intervention study, 50 healthy South Asians will be randomised to receive either a DHRMA (reduced GI) supply of chapatti (bread), stone ground, high protein wheat flour and white basmati rice (high bran, unpolished) or commercially available (leading brand) versions chapatti wheat flour and basmati rice. Volunteers will be asked to complete a 75g oral glucose tolerance test at baseline and at 10-weeks follow-up, where blood metabolites and hormones, blood pressure and anthropometry will also be assessed in a standardised manner.</p> <p>Discussion</p> <p>It is anticipated that the information collected from this study help develop healthy diet options specific (but not exclusive) for South Asian ethnic communities.</p> <p>Trial registration</p> <p>Current Controlled Trials <a href="http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=ISRCTN02839188">ISRCTN02839188</a></p
