Abstract

The paper introduces results of computational fluid dynamics (CFD) simulations of water flow at the reactor pressure vessel (RPV) outlet and under the RPV head. Several CFD calculations of the steady-state and dynamic processes involving forced and natural circulation of coolant are presented in the paper. In the steady state regime, several calculations were performed for various number of the reactor coolant system (RCS) loops connected to the reactor and the results have been used to analyse the effect of the RCS configuration to the coolant flow at the reactor outlet and under the reactor vessel head. General flow patterns are described in the outlet part of the reactor and under the reactor vessel head and, also, the influence of a lower flow rate through the reactor on thermal homogeneity of coolant under the vessel head. Simultaneously, we discuss the influence of the coolant flow rate at the core outlet on the heat transfer from the under-head space. Unsteady calculation was also done for a reactor cool-down in the regime of natural circulation. The calculation conditions correspond with the data obtained from the experiments led in the frame of the cool-down process of VVER440 reactor at Mochovce nuclear power plant in 2003. In the calculations, the main attention was applied to establishing the basic trends in the cool-down of water content at the outlet part of the reactor and under the head of the reactor vessel.

Abstract

Introduction: Vagus nerve stimulation is a palliative treatment for patients with refractory epilepsy to reduce the frequency and intensity of seizures. A bipolar helical electrode is placed around the left vagus nerve at the cervical level and is connected to the pulse generator placed in a subcutaneous pocket, most commonly in the subclavian region. Methods: Between March 1998 and October 2019, we performed 196 procedures related to the vagal nerve stimulation at the Neurosurgery Department in Motol University Hospital. Of these, 126 patients were vagal nerve stimulator implantation surgeries for intractable epilepsy. The cases included 69 female and 57 male patients with mean age at the time of the implantation surgery 22±12.4 years (range 2.1−58.4 years). Results: Nine patients (7.1%) were afflicted by complications related to implantation. Surgical complications included postoperative infection in 1.6%, VNS-associated arrhythmias in 1.6%, jugular vein bleeding in 0.8% and vocal cord paresis in 2.4%. One patient with vocal cord palsy also suffered from severe dysphagia. One patient (0.8%) did not tolerate extra stimulation with magnet due to a prolonged spasm in his throat. The extra added benefit of vagus stimulation in one patient was a significant reduction of previously regular severe headaches. Conclusion: Vagus nerve stimulation is an appropriate treatment for patients with drug-resistant epilepsy who are not candidates for focal resective surgery. Implantation of the vagus nerve stimulator is a relatively safe operative procedure.

26. Upstream expansion of round goby (Neogobius Melanostomus) – first record in the upper reaches of the Elbe river

Abstract

The round goby Neogobius melanostomus (Pallas, 1814) is one of the most problematic invasive fish species in recent years in Europe. It has proliferated from its native Ponto-Caspian region to several European river systems including their mouths and coastal brackish waters and was also introduced to and became widely established in the Great Lakes in North America. Despite recent reports about further invasions of round goby in the Odra and Vistula Rivers, including penetration of Baltic and North Seas, in the Elbe River this species was only recorded near its mouth close to Hamburg. Here we report the occurrence of round goby 622 km upstream from the previous record in Geesthacht (Germany) in the upper part of the Elbe River in Usti nad Labem (Czech Republic). This report illustrates the fast spread of round goby through several possible pathways, but the most certain is an introduction in ballast water.

Abstract

Aim: An overview of MRI in patients with implanted vagal nerve stimulator (VNS) and the method of surgical explantation of VNS, reflect--ing the MRI protocol al-low--ing the subsequent MRI examination without significant limitations. Patients and methods: MRI can also be safely performed in patients with the implanted VNS device. Head examination and body examination caudal-ly from Th8 can be performed, but only local radiofrequency coils must be used. Before the MRI, the VNS system must be reprogram-med. If the patient has an explanted generator and the larger part of the electrode, the MRI of the entire body can be performed with any com-mon MRI setting. This applies to a situation where after the explantation there is only a 2- cm part of the electrode left –  cor-respond--ing to the portion of the electrode on the vagal nerve with fixation anchors. Results: From June 2016 to June 2018, we explanted a VNS with this approach in six patients. Post-operative course of all patients was without complications. Post-operative control was performed using neck X-ray and CT 3D imaging. Imag--ing methods showed that the remainder of the electrode on the vagal nerve electrode was ≤ 2 cm. Post-operatively, patients did not have swallowing dif-ficulties, hoarseness or voice changes. Four patients have subsequently already undergone MRI without any dif-ficulties or complications. Conclusion: Surgical explantation of VNS accord--ing to the MRI protocol, leav--ing part of the electrode on the vagal nerve and omitt--ing the complete preparation of the entire electrode on the nerve, reduces the risk of complications and shortens the duration of the operation. The patient can afterwards safely undergo the MRI of the entire body without any limitations in normal technical settings.
