Holomorphic Approximation via Dolbeault Cohomology

The purpose of this paper is to study holomorphic approximation and approximation of $\bar\partial$-closed forms in complex manifolds of complex dimension $n\geq 1$. We consider extensions of the classical Runge theorem and the Mergelyan property to domains in complex manifolds for the smooth and the $L^2$ topology. We characterize the Runge or Mergelyan property in terms of certain Dolbeault cohomology groups and some geometric sufficient conditions are given

Pain management skills of regional nurses caring for older people with dementia: a needs analysis

An exploratory survey of the pain management education needs of 197 nurses working with older people with dementia was undertaken in a regional area of Queensland, Australia. The analysis indicated that nurses in this setting might not have the knowledge base to manage pain effectively; and that respondents have essentially negative perceptions of the availability and appropriateness of current pain management education programs. Consistent with non-metropolitan nurses generally, respondents expressed a preference for pain management education that had a significant face-to-face component allied with ongoing mentorship and support on completion of the program. The obstacles to attending such programs were also typical of the problems facing regional and rural nurses throughout Australia. These were identified as inability to pay for courses; lack of information on what is available; distance to travel to education; and a perceived lack of employer support due to an inability to replace those staff attending education. Positive aspects include the degree to which participants were responsive and interested in dementia pain management and their access to, and acceptance of, non-medical pain therapies. The findings suggest a definite need for a dementia pain management program for aged care nurses, specifically tailored to their needs and to the constraints of the regional practice setting

Phase and antigenic variation in mycoplasmas

With their reduced genome bound by a single membrane, bacteria of the Mycoplasma species represent some of the simplest autonomous life forms. Yet, these minute prokaryotes are able to establish persistent infection in a wide range of hosts, even in the presence of a specific immune response. Clues to their success in host adaptation and survival reside, in part, in a number of gene families that are affected by frequent, stochastic genotypic hanges. These genetic events alter the expression, the size and the antigenic structure of abundant surface proteins, thereby creating highly versatile and dynamic surfaces within a clonal population. This phenomenon provides these wall-less pathogens with a means to escape the host immune response and to modulate surface accessibility by masking and unmasking stably expressed components that are essential in host interaction and survival

Spatial Point Pattern Analysis of the Unidentified Aerial Phenomena in France

We model the unidentified aerial phenomena observed in France during the last 60 years as a spatial point pattern. We use some public information such as population density, rate of moisture or presence of airports to model the intensity of the unidentified aerial phenomena. Spatial exploratory data analysis is a first approach to appreciate the link between the intensity of the unidentified aerial phenomena and the covariates. We then fit an inhomogeneous spatial Poisson process model with covariates. We find that the significant variables are the population density, the presence of the factories with a nuclear risk and contaminated land, and the rate of moisture. The analysis of the residuals shows that some parts of France (the Belgian border, the tip of Britany, some parts in the SouthEast , the Picardie and Haute-Normandie regions, the Loiret and Corr eze departments) present a high value of local intensity which are not explained by our model
