The primary objective of the study was to evaluate baseline patient perception on single versus multiple community pharmacy systems. The secondary objective was to determine effects of a pharmacist provided educational intervention on perception of using a single community pharmacy system. This was a prospective survey based study implemented in a single grocery store chain pharmacy and one location of a large retail pharmacy. An anonymous pre-survey was administered to eligible patients. The primary investigator then delivered a brief educational intervention followed by an anonymous post survey. This aimed to determine if there was a change in perception of components assessed in the pre-survey. Data analysis was performed using descriptive statistics. Subjects reported using approximately 1.5 pharmacies. Major reasons included cost, location, and immunizations. 63% of subjects answered that their pharmacist will not have an accurate medication list when using multiple pharmacies, however, 92% of subjects responded that the pharmacist should be aware of all medications they take. Education on multiple pharmacy use may help protect against its risks. Cognizance of medications filled at other pharmacies and close communication between patients and pharmacists may help foster pharmacist-patient relationships while reducing the risk of multiple pharmacy use.

在始新世中期至渐新世早期，欧洲板块和亚得里亚板块发生碰撞，导致了阿尔卑斯造山带的大规模岩浆活动，由于后期隆升剥蚀无法保存，而弧后盆地中同时期的沉积火山碎屑岩记录了这一构造事件。本文针对该套沉积火山碎屑岩，开展了地质年代学与地球化学等方面的研究，揭示了阿尔卑斯造山带的火山活动和构造演化特征。本次研究表明：火山碎屑岩中的锆石年龄峰值主要集中在～47Ma、40Ma和37Ma，并且锆石的Hf同位素呈现负值，说明其主要形成于板块俯冲过程中部分地壳熔融的岩浆中。此外，通过对岩浆锆石同位素计算地壳厚度的变化，说明了阿尔卑斯造山带不仅存在由于板块俯冲碰撞引起的地壳垂直挤压增厚，还存在俯冲板片拉伸引起的地壳伸展变薄。

This paper presents the algebro-geometric method for computing explicit formula solutions for algebraic differential equations(ADEs). An algebraic differential equation is a polynomial relation between a function, some of its partial derivatives, and the variables in which the function is de?*** all these quantities as unrelated variables, the polynomial relation leads to an algebraic relation de?ning a hypersurface on which the solution is to be found. A solution in a certain class of functions, such as rational or algebraic functions, determines a parametrization of the hypersurface in this class. So in the algebro-geometric method the author ?rst decides whether a given ADE can be parametrized with functions from a given class; and in the second step the author tries to transform a parametrization into one respecting also the differential conditions. This approach is relatively well understood for rational and algebraic solutions of single algebraic ordinary differential equations(AODEs). First steps are taken in a generalization to systems and to partial differential equations.

This paper deals with the Neumann initial-boundary value problem for a classical chemotaxis system with signal consumption in a *** contrast to previous studies which have established a comprehensive theory of global classical solutions for suitably regular nonnegative initial data,the focus in the present work is on the question to which extent initially prescribed singularities can be regularized despite the presence of the nonlinear cross-diffusive *** main result in this paper asserts that at least in the framework of radial solutions immediate regularization occurs under an essentially optimal condition on the initial distribution of the population *** precisely,it will turn out that for any radially symmetric initial data belonging to the space of regular signed Borel measures for the population density and to L^(2) for the signal density,there exists a classical solution to the Neumann initial-boundary value problem,which is smooth and approaches the given initial data in an appropriate trace sense.
