Shock tube study of JP-10 ignition delay time
No full textJP-10 (exo-tetrahydrodicyclopentadiene, C10H16) ignition delay times were measured in a preheated shock tube. The vapor pressures of the JP-10 were measured directly by using a high-precision vacuum gauge, to remedy the difficulty in determining the gaseous concentrations of heavy hydrocarbon fuel arising from the adsorption on the wall in shock tube experiments. The whole variation of pressure and emission of the OH or CH radicals were observed in the ignition process by a pressure transducer and a photomultiplier with a monochromator. The emission of the OH or CH radicals was used to identify the time to ignition. Experiments were performed over the pressure range of 151-556 kPa, temperature range of 1000-2100 K, fuel concentrations of 0.1%-0.55% mole fraction, and stoichiometric ratios of 0.25, 0.5, 1.0 and 2.0. The experimental results show that for the lower and higher temperature ranges, there are different dependency relationships of the ignition time on the temperature and the concentrations of JP-10 and oxygen
Dynamics of Network Formation Processes in the Co-Author Model
Full text linkThis article studies the dynamics in the formation processes of a mutual consent network in game theory setting: the Co-Author Model. In this article, a limited observation is applied and analytical results are derived. Then, 2 parameters are varied: the number of individuals in the network and the initial probability of the links in the network in its initial state. A simulation result shows a finding that is consistent with an analytical result for a state of equilibrium while it also shows different possible equilibria.Dynamics, Network, Game Theory, Model,Simulation, Equilibrium, Complexity
An equivalent formulation of the Fan-Raspaud Conjecture and related problems
Full text linkIn 1994, it was conjectured by Fan and Raspaud that every simple bridgeless cubic graph has three perfect matchings whose intersection is empty. In this paper we answer a question recently proposed by Mkrtchyan and Vardanyan, by giving an equivalent formulation of the Fan-Raspaud Conjecture. We also study a possibly weaker conjecture originally proposed by the first author, which states that in every simple bridgeless cubic graph there exist two perfect matchings such that the complement of their union is a bipartite graph. Here, we show that this conjecture can be equivalently stated using a variant of Petersen-colourings, we prove it for graphs having oddness at most four and we give a natural extension to bridgeless cubic multigraphs and to certain cubic graphs having bridges
Ephemisms as communication vehicle in the Tiv language and literature
No full textThe beauty of Tiv language and literature is achieved when communication or discourse is laced with euphemistic expressions. Euphemisms aid in turning impolite utterances into polite ones. This study, therefore, investigates the communicative potentials of euphemisms in the Tiv language and literature. The study discusses formations of euphemisms, classifies euphemisms and explores the effects of euphemisms. Connotative theory of meaning has been deployed in this study because the interpretation of euphemisms is contextually and connotatively loaded. Methodologically, the author used primary and secondary materials. The author used a participant-observation tool for data collection. Being a native speaker of the Tiv language, the author collected, translated and classified euphemisms. Secondary materials were sourced from textbooks, journal articles, online sources and dictionaries. The following findings were made: euphemisms constitute phrasal or idiomatic synonyms; they beautify or spice our daily communication; they can becloud meanings. This study will benefit preachers, writers, lecturers/teachers, researchers, semanticists, public speakers, politicians and students
Open Access to Peer-Reviewed Research through Author/Institution Self-Archiving: Maximizing Research Impact by Maximizing Online Access
No full textAll refereed journals will soon be available online; most of them already are. This means that anyone will be able to access them from any networked desk-top. The literature will all be interconnected by citation, author, and keyword/subject links, allowing for unheard-of power and ease of access and navigability. Successive drafts of pre-refereeing preprints will be linked to the official refereed draft, as well as to any subsequent corrections, revisions, updates, comments, responses, and underlying empirical databases, all enhancing the self-correctiveness, interactivity and productivity of scholarly and scientific research and communication in remarkable new ways. New scientometric indicators of digital impact are also emerging <http://opcit.eprints.org> to chart the online course of knowledge. But there is still one last frontier to cross before science reaches the optimal and the inevitable: Just as there is no longer any need for research or researchers to be constrained by the access-blocking restrictions of paper distribution, there is no longer any need to be constrained by the impact-blocking financial fire-walls of Subscription/Site-License/Pay-Per-View (S/L/P) tolls for this give-away literature. Its author/researchers have always donated their research reports for free (and its referee/researchers have refereed for free), with the sole goal of maximizing their impact on subsequent research (by accessing the eyes and minds of fellow-researchers, present and future) and hence on society. Generic (OAi-compliant) software is now available free so that institutions can immediately create Eprint Archives in which their authors can self-archive all their refereed papers for free for all forever <http://www.eprints.org/>. These interoperable Open Archives <http://www.openarchives.org> will then be harvested into global, jointly searchable "virtual archives" (e.g., <http://arc.cs.odu.edu/>). "Scholarly Skywriting" in this PostGutenberg Galaxy will be dramatically (and measurably) more interactive and productive, spawning its own new digital metrics of productivity and impact, allowing for an online "embryology of knowledge.
A multifaceted perspective on skin cancer prevention
Full text linkSolar ultraviolet radiation has been acknowledged as the main culprit for the three major
types of skin cancer which are among the most numerous (basal cell carcinoma [BCC],
squamous cell carcinoma [SCC]) and most dangerous (cutaneous malignant melanoma)
malignancies in Caucasian populations.
The present thesis comprises six individual projects providing a multifaceted perspective on
the prevention of these tumours.
Project I evaluated a school-based sun safety education programme developed by the Swiss
Cancer Leagues. Primary school students in the Canton of Zurich (North-Eastern Switzerland)
were asked to answer a questionnaire regarding their sun-related knowledge, behaviour,
and sunburn experience shortly before and one year after the intervention (repeated cross-
sectional assessment). Based on the data from more than 3000 students, the sun safety
education programme was effective in sustainably improving children’s sun-related
knowledge and possibly to some extent in decreasing sunburn rates, but had no obvious
impact on the examined sun protective behaviours (use of sunscreen, seeking shade).
Project II represents a systematic review of cross-sectional and interventional studies on
sun-related knowledge, attitudes, and protective behaviours of outdoor workers. The 52
relevant publications identified through an electronic search of medical literature databases
(PubMed, Embase, PsycINFO) and an extensive hand search suggested that outdoor workers’
sun protective behaviours are largely inadequate and sunburn rates are high (50-80% per
season). However, there is evidence that sun safety education in outdoor occupational
settings is effective in increasing workers’ protective behaviours and presumably also in
reducing sunburn incidence.
Project III investigated sun protective behaviour and sunburn experience of vacationers
spending holidays in the tropics or subtropics. The 1165 standardised face-to-face interviews
conducted among air passengers waiting in the departure or baggage claim area at the
Airport Basel-Mulhouse (Switzerland/France) and among vacationers waiting for pre-travel
health advice at the Travel Clinic of the Swiss Tropical and Public Health Institute Basel
(Switzerland) revealed that almost all respondents used sunscreen at the holiday
destination. Nevertheless, wearing a sunhat and protective clothing as well as seeking shade
were clearly less common sun protection methods. The assessed sunburn rate among the
324 interviewed returning air passengers was alarmingly high, with 44% having suffered
from sunburn during their holiday stay.
Project IV comprehensively analysed the content and quality of 2103 print media articles
pertaining to skin cancer prevention and related topics (solaria, vitamin D) published in
Germany and Switzerland over a one-year period (2012-2013). Whereas skin cancer
secondary prevention received little press attention, primary prevention was a frequently
covered media topic. However, the delivered information was generally rather superficial. By
far the most common and often sole sun protection recommendation made was the use of
sunscreen. In total, 27% of all analysed articles contained misleading or erroneous
statements which were mostly related to the use of sunscreen and vitamin D issues.
Projects V and VI are based on data derived from the Clinical Practice Research Datalink, a
large, well-validated primary care database established in the United Kingdom (UK).
Project V estimated BCC incidence in the UK and characterised affected patients regarding
lifestyle factors and comorbidities. The calculated age-standardised BCC incidence in adults
rose from 119 to 165 per 100 000 person-years between the years 2000 and 2011. According
to the matched case-control analysis including 57 121 BCC cases and 57 121 BCC-free
controls, BCC risk was slightly increased in alcohol drinkers, but reduced in smokers and in
individuals with a body mass index outside the normal range. BCC was associated with
various comorbidities related to iatrogenic or non-iatrogenic immunosuppression.
Project VI explored whether patients regularly exposed to systemic nonsteroidal anti-
inflammatory drugs (NSAIDs) are at a reduced risk of nonmelanoma skin cancer (NMSC). The
matched case-control analysis comprised 65 398 BCC cases, 65 398 BCC-free controls, 7864
SCC cases, and 31 456 SCC-free controls. Overall, NSAID use was not negatively associated
with BCC, but when looking exclusively at users of single NSAID substances there was a
suggestion of a reduced BCC risk in regular users of aspirin and ibuprofen. SCC risk was
slightly decreased in regular users of any NSAIDs, with the strongest risk reduction observed
in current users of coxibs. These findings provide evidence that patients predisposed to
NMSC may benefit from chemoprevention with NSAIDs
Why hasn't electronic bill presentment and payment taken off?
Full text linkThe delivery and payment of bills over the Internet could offer many advantages—low processing costs and enhanced marketing opportunities for billers, savings in time and postage for customers. Nevertheless, electronic billing has not found favor with potential users. A lack of coordination among billers and customers, combined with the high fixed costs of the new technology, may help account for the cool reception.Electronic funds transfers ; Electronic commerce ; Technology ; Payment systems
