Arterial hypertension is the leading risk mortality factor in the world according to the report by the World Health Organization. The aim of this research was to compare fixed-dose combination with free-drug combination therapy and prove that fixed-dose combination improve patient compliance and persistence, measuring blood pressure among hypertensive patients in a Croatian Adriatic city. Methods： The study included 202 patients, 101 women and 101 men, mean age 66.8 4- 9.4 with previous diagnosis of hypertension. Results： Mean blood pressure was 152.8 4- 18.8/87.3 4- 10.3 mmHg. Blood pressure control 140/90 mmHg） was achieved in 24.8% of patients, 13.9% of women and 10.9% of men. Mean blood pressure in the group with fixed-dose combination was 149.2 4- 17.9/86.2 4- 8.5 mmHg, and 156.7 4- 18.9/88.4 4- 11.8 mmHg in the group with free-drug combination therapy. Conclusions： Results suggest that blood pressure control was better in patients with fixed-dose combinations than in patients with free-drug combinations. Fixed-drug combination improved compliance and adherence in patients with antihypertensive therapy. Results of the study indicate that fixed-drug combination should be considered in patients with hypertension according to the guidelines.

把新建船舶从船台移入水中的过程称为船舶下水。下水后船舶才开始她的生命之旅。纵向下水是一种使用广泛的传统下水方法,也是最复杂的下水方法之一。通常纵向下水可以分为前后相连的四个阶段:起动,入水,艉浮与漂浮。整个下水过程虽然只有短短的一、二分钟,但却隐藏着各种潜在的风险。假如没有精确地纵向下水模拟,无法预测和避免风险地情况。另一方面,在现代船舶结构设计中CAD软件是一种标准设计工具。设计的船体可以以数字形式导出,如IGES,STEP或ACIS文件。这种文件包括详细记录2D或3D几何模型。对于船体与复杂结构数字形式有优势。有鉴于此,本文基于IGES文件,为了生成船体表面应用NURBS曲面数字模型。为了应用NURBS曲面数字模型开发了用户友好的MatLab计算程序。基于各船体NURBS曲面数字模型建立了船舶纵向下水过程的具体数值模拟方法。对船尾纵向下水过程中的四个阶段,根据各自的运动微分方程,分别得出了纵向下水速度随距离的变化。该计算程序能直接从IGES文件读取NURBS曲面的消息,由此计算出船体处于任意位置的湿表面积,排水体积,浮力,浮心,进而计算出下水速度与加速度等。终于,对一艘3100TEU集装箱船系统地探讨下水的质量,滑道斜度,滑道摩擦系数,滑道长度与水位高度主要下水参数的改变对下水过程产生的影响。计算的船舶静力学验证通过商业软件得到的结果比较。研究表明,本文提出的基于NURBS曲面数字模型的船舶静力学与船舶纵向下水的新的模拟方法和计算程序是可行的,而且也很容易根据不同需求对模拟方法和计算程序进行改进。

In power systems, a large number of OPLs （overhead power lines） are more than 40 years old and some even exceed 50 years old. The key issue for power systems managers, public utilities companies and electrical engineers today concerns the manner in which available financial resources should be invested in these OPLs to provide the greatest impact on the power system as a whole and to address the OPLs that require urgent revitalization. This paper presents the application of the software tool RevOPL, developed using Microsoft Access utilizing the ＂methodology for revitalization of high-voltage OPLs＂. The aim is to present both the methodology and software to objectively evaluate the condition of an OPL and determine its remaining service life. The application of this software tool provides a proposal for the scheduling and scope of planned revitalization activities, which are obtained through the optimization of the technical characteristics while remaining within the available budget.

Quality control is an important part of the capacitors automatic assembly process. Traditionally this control is being realized through a series of electrical measurements including capacity, tension, and tgct. In most cases, these measurements are not suitable for detecting defects that appear as a result of failures of certain elements of the assembly lines. These so called self-recovering failures very often remain unnoticed, because they do not cause a suspension of the assembly process and if not taken into consideration, they can seriously menace the final product quality. In this paper, the authors use PFMEA to identify and evaluate the risk of the self-recovering failures. They also propose a simple Simulink model, which could be useful when trying to estimate the effect of installing new control devices at an existing assembly line upon its overall reliability and productivity.

The optimization process of embedded, or DG （distributed generation） is a very complex task, and it should be evaluated and compared by means of multi-criteria methods of analysis. The classical method for selection is usually based only on a single criterion analysis, and it is defined by thermal or economic aspects. The problem of optimal dispatch of DG is typical example of optimization, because it differs from the classical problem of generation dispatch in the power system, due to the specific criteria related to the DG interconnection. The most important goals are to maximize the renewable production and to minimize the total cost, while satisfying additional constraints related to the operation of a distribution network. As there are many DGs in a distribution network, it is very complicated to decide the optimal DG outputs to satisfy all the criteria and constraints imposed by the distribution network. Another problem is the lack of the dispatcher control over DGs, and very often, the only available action is to switch on or off the generator. Finally, network operator and DG owner perspective are often opposed regarding appropriate control action in the network. In this paper, a multicriteria decision support based on AHP （analytical hierarchical processes） method is proposed for the choice of the dispatching action. The method is illustrated on the choice of the DG to be switched off in the case or reverse power flow.
