Dataset concerning the analytical approximation of the Ae3 temperature.

In this paper we present a new polynomial function for calculating the local phase transformation temperature (Ae3 ) between the austenite+ferrite and the fully austenitic phase fields during heating and cooling of steel:[Formula: see text] The dataset includes the terms of the function and the values for the polynomial coefficients for major alloying elements in steel. A short description of the approximation method used to derive and validate the coefficients has also been included. For discussion and application of this model, please refer to the full length article entitled "The role of aluminium in chemical and phase segregation in a TRIP-assisted dual phase steel" 10.1016/j.actamat.2016.05.046 (Ennis et al., 2016) [1]

Issues and trends in the provision of public library services in Nigeria: A literature survey

The philosophy, orientation and nature of public library are routed in the responsibility of disseminating diverse and current information services to the members of its community. Waller and Mcshare (2008) posit two major challenges in the provision and use of public library services which are; lack of obtaining a thorough understanding of the nature of the environment which bothers majorly on information provision and use; and the development of policy frameworks that clarifies institutions goals and brings coherence to diverse and sometimes conflicting policy demands. This paper looks at issues and trends concerning some of the challenges bedeviling the provision and utilisation of public library services in Nigeria such as in-appropriate policies, lack of sufficient professionals, inadequate facilities and services and lack of awareness and proper understanding of the concept of public library services which led to non-use of the available services by potential users. Yield shift theory of satisfaction phenomena was used to explain the satisfaction phenomenon of public library services by users. Identified challenges were discussed and recommendations made towards developing a framework for improved public library services in Nigeria

Circulation Tumor Cells: counts and characteristics

In recent years, many new anti-cancer agents have been developed and introduced into clinical care. While these new agents have led to substantial gains in response rates and life expectancies, they have also increased the need for tools to select those patients benefitting from said therapies. Once patients develop metastatic disease, treatment is aimed at improving quality of life and prolonging life expectancy, but is always a trade-off against the side-effects that are inevitably associated with anti-tumor therapy, underscoring the need to select only those patients who are likely to respond to a particular drug. However, there is still an unmet need for such an array of reliable predictive factors, a need that can be met by designing studies in which patient subgroups are defined and stratified based on rational, biology-driven but feasible tumor characteristics. An increasing number of studies is being designed in which, for example, only patients with a specific gain-of-function mutation are subjected to a monoclonal antibody therapy aimed at the activated pathway this gene is involved in. While substantial progress is being made with this approach, patient selection has thus far been far from perfect. Even a powerful predictor such as a KRAS mutation for EGFR-inhibiting therapy results in a response in just 20% of patients who are deemed sensitive based on their KRAS wild-type status. One of the reasons for the disappointing performance of predictive factors could be the fact that they are most often based on primary tumor characteristics, while at the time of metastatic disease, a patients’ prognosis is determined by their metastatic tumor load and its biological phenotype. Through processes such as clonal selection and the inherent genomic instability of the tumor or as a consequence of therapy pressure, metastatic tumor cells can differ substantially and vitally from primary tumor cells. Analysis of metastatic tissue would thus probably be better indicative of the actual tumor load and its underlying biology, and lead to better response prediction. Unfortunately, repetitive metastatic biopsies are invasive and painful, understandably limiting their use in clinical practice. Circulating tumor cells (CTCs) provide a very promising solution for this problem, as they can be obtained and characterized repetitively and non-invasively through venipunctures, and thus serve as a surrogate ‘liquid biopsy’ of metastases

Some classifications of biharmonic hypersurfaces with constant scalar curvature

We give some classifications of biharmonic hypersurfaces with constant scalar curvature. These include biharmonic Einstein hypersurfaces in space forms, compact biharmonic hypersurfaces with constant scalar curvature in a sphere, and some complete biharmonic hypersurfaces of constant scalar curvature in space forms and in a non-positively curved Einstein space. Our results provide additional cases (Theorem 2.3 and Proposition 2.8) that supports the conjecture that a biharmonic submanifold in a sphere has constant mean curvature, and two more cases that support Chen's conjecture on biharmonic hypersurfaces (Corollaries 2.2,2.7).Comment: 11 page

Popular progression differences in vector spaces II

Green used an arithmetic analogue of Szemer\'edi's celebrated regularity lemma to prove the following strengthening of Roth's theorem in vector spaces. For every $\alpha>0$, $\beta<\alpha^3$, and prime number $p$, there is a least positive integer $n_p(\alpha,\beta)$ such that if $n \geq n_p(\alpha,\beta)$, then for every subset of $\mathbb{F}_p^n$ of density at least $\alpha$ there is a nonzero $d$ for which the density of three-term arithmetic progressions with common difference $d$ is at least $\beta$. We determine for $p \geq 19$ the tower height of $n_p(\alpha,\beta)$ up to an absolute constant factor and an additive term depending only on $p$. In particular, if we want half the random bound (so $\beta=\alpha^3/2$), then the dimension $n$ required is a tower of twos of height $\Theta \left((\log p) \log \log (1/\alpha)\right)$. It turns out that the tower height in general takes on a different form in several different regions of $\alpha$ and $\beta$, and different arguments are used both in the upper and lower bounds to handle these cases.Comment: 34 pages including appendi

Job characteristics and coping strategies associated with negative and positive work-home interference in a nursing environment

The aim of this study is to determine which job characteristics and coping strategies predict negative and positive work-home interference (WHI) in the nursing environment. Random samples (n=300) were taken of registered nurses in the Johannesburg, Klerksdorp, Krugersdorp, Potchefstroom and Pretoria regions. A self-constructed questionnaire was used to measure job characteristics. The Coping Strategy Indicator (CSI) was used to measure coping strategies, and the Survey Work-Home Interaction-Nijmegen (SWING) to measure WHI. The results show that time demands, pressure, role clarity and colleague support are the main job characteristics that predict negative WHI. Problem-solving coping predicts less negative WHI and avoidance coping predicts more negative WHI. Time demands, autonomy and role clarity are the main variables that predict positive WHI. Problem-solving coping is the only coping strategy that predicts positive WHI

Waardevol - Indicatoren voor Valorisatie

Het rapport Waardevol – Indicatoren voor valorisatie biedt kennisinstellingen, wetenschapsfinanciers en kennisgebruikers een gemeenschappelijk kader voor valorisatie. De methode werkt met valorisatiekaarten waarmee betrokken organisaties systematisch kunnen monitoren hoe groot de valorisatie-inspanningen zijn, wat de opbrengsten zijn en welke mogelijkheden voor verbetering er zijn. Het gebruik van valorisatiekaarten zal helpen om het inzicht te vergroten in wat publieke kennisinstellingen, wetenschapsfinanciers en bedrijfsleven nu al doen aan valorisatie.
