Battery Charger for Hybrid Locomotive

The paper introduces the concept and functionality of the battery charger – pulse rectifier control system for hybrid shunting locomotive. The locomotive producer is the company CZ LOKO a.s. The pulse rectifier operates in several modes including modes with charging of the traction battery from the alternator or from the distribution net, emergency mode or test modes. The paper presents the integration of the pulse rectifier into the context of the hybrid drive and the results of partial tests of drive control

Nanofibers in Mucosal Drug and Vaccine Delivery

Successful mucosal administration and delivery of drugs still pose a great challenge. However, the possibility to deliver not only small drug molecules but also macromolecular drugs and nanoparticles via mucosal surfaces represents a great opportunity. Rapid onset of drug action, avoidance of first-pass metabolism, and high immunocompetence of mucosa are some of the important features for mucosal drug and vaccine delivery. The use of mucoadhesive drug delivery systems, systems with fast dissolving properties, and nanomaterials with mucus penetration properties are examples of successful strategies to achieve effective mucosal drug and vaccine delivery. Non-keratinized mucosa of the oral cavity, the nasal and vaginal mucosa represent favorable sites of drug administration. Polymer nanofibers have attracted much attention because of remarkable characteristics such as a large surface area to volume ratio and high porosity. Nanofibers have been extensively used for different biomedical applications including wound dressing, tissue engineering, and drug delivery. Among their fabrication methods, the introduction of electrospinning technique was an important step toward achieving the goal of large scale industrial production of nanofiber-based drug delivery systems used in mucosal applications. This chapter provides an overview on all aspects of mucosal drug and vaccine delivery using nanofibers

Qualification and personal prerequisites for the profession of vocational training teacher

This bachelors thesis deals with the qualification and personal prerequisites for the profession of vocational training teacher. It points out not only the qualification of the pedagogical worker, his legal constraints and possible exceptions, obligations and rights but also his preconditions, which are a vital part of the teaching profession. The work aims to show the importance of quality education of teachers of vocational training both in terms of vocational and pedagogical, which should be an integral part of the requirements for teachers in Czech education system. The work consists of a theoretical and practical part. The former further is divided into three chapters, and the latter is consisted of a case study. The first chapter deals with the qualifications of pedagogical staff, their exceptions, obligations and rights of teachers. The second focuses on the teacher's personality. So the prerequisites for the profession's performance, the typology and temperament of the teacher are addressed. The third compares the course of the pedagogical minimum, its content, the range of information, knowledge and skills with the bachelor's study. The practical part is a case study of SOU Sedlčany employees. I have focused on their education, years of pedagogical practice, deepening and expanding..

Influence of the CNB's unconventional monetary policy on inflation in the Czech Republic

Hlavním tématem práce je zjistit, zda kurzový závazek ČNB zabránil pádu do deflační spirály. Samotný pojem deflační spirály je však v měnověpolitické teorii stále významnou neznámou, tudíž nelze jednoznačně určit, zda by se česká ekonomika v případě hlubšího pádu cenové hladiny začala stáčet do deflační spirály. Jelikož však soudobá měnověpolitická teorie zatím nedokázala poskytnout argumenty, na základě kterých by šlo potvrdit, že české republice pád do deflační spirály nehrozil, považuji jednání ČNB za adekvátní v souladu se soudobou měnověpolitickou teorií. Česká národní banka pomocí kurzového závazku postupně docílila zvýšení inflačních očekávání, a tím snížení reálné úrokové sazby. Na základě analýzy odborných článků tak docházím k závěru, že kurzový zavazek zabránil dalšímu poklesu cenové hladiny, případně přijmeme-li argumentaci ČNB, pádu do deflační spirály.The main theme of the work is to find out whether the exchange rate commitment of the CNB prevented the fall into the deflationary spiral. The deflation spiral itself is still notable in the monetopolitical theory, so it is not possible to determine whether the Czech economy would begin to overflow into a deflationary spiral or not in the event of a longer decline in the price level. However, since current monetary policy theory has not yet been able to provide arguments for confirming that the deflationary spiral has not penetrated the Czech Republic, I consider the CNB's conduct to be in line with current monetary policy theory. The Czech National Bank, through its exchange rate commitment, has gradually increased its inflation expectations, thereby reducing the real interest rate. On the basis of the analyzed articles, it concludes that the exchange rate commitment prevents a further drop in the price level, or if we accept the CNB's arguments, into the deflationary spiral

New Training Schemes for The Future Education in Railway Sector

Railway transport is a sector that is rapidly developing, changing and being influenced to the maximum extent by the technological development and innovation, among others, thus facing problems in staffing its several domains with appropriate and qualified personnel.
