Abstract:
Abstract Background and study aims Bleeding from isolated gastric varices type I (IGV1) is more dangerous and fatal than other types of esophageal variceal hemorrhages. However, optimum treatment for bleeding from IGV1 remains undefined. This retrospective study compared the efficacy of endoscopic clipping prior to N-butyl-2-cyanoacrylate injection (GVO) and only GVO for treatment of IGV1. Patients and methods Data were collected retrospectively at three medical centers. Ninety-six patients were enrolled between March 2015 and April 2017 and divided into two groups: group I (patients with endo

Abstract:
Gegenwärtig nimmt weltweit die Anbaufläche von gv-Mais stetig zu. 2006 wurde auf über 25 Mio Hektar gv- Mais angebaut. 2007 erhöhte sich der Anbau um fast ein Drittel auf 32,5 Mio ha. In der Europäischen Union (Anbaufläche: 110 000 ha) hat Spanien mit 75 000 ha den größten Anteil an gv-Mais [1]. In Deutschland wurden 2007 insgesamt 2 685 ha angebaut. Sachsen nahm mit 556 ha (2006: 230 ha) nach Brandenburg und Mecklenburg-Vorpommern den dritten Platz innerhalb der deutschen Bundesländer ein [2]. Von gv-Maissorten werden beträchtliche Ertragssteigerungen bzw. eine Ertragsstabilisierung erwartet

This paper aims at developing a real-time, robust, and reliable navigation method for an omnidirectional robot, the so-called MRL-SSL RoboCup robot, can be used in crowded dynamically-changing environments.

The proposed method considers not only the kinematics of the robot but also its dynamics. Moreover, it could be extended to a wide range of pract

In present work, two runners tested by experiments, the runner A with a negative and the runner B with a positive blade lean at leading edge, were studied in CFD mode with a reduced scale model.

Abstract Oscillating water columns (OWC) are widely used devices for the extraction of wave energy through self -rectifying impulse air turbines. To improve the performance of any turbo-machinery, guide vanes (GV) play an essential role in deciding turbine characteristics in terms of efficiency and torque. The concept of filleting is used in the GVs of bidirectional impulse turbine (BDI) with five different types of GV fillets for different radii, and the performance was analyzed. The numerical simulation was done using the commercial code ANSYS CFX 16.2, which solves the three-dimensional Rey
