The Role of CIS in the U-space Environment

The aim of this paper is to determine the role of Common Information Service (CIS) in the U-space environment. Ensuring the correct role of the CIS and all high-level connections is the first step to implementing U-space in specific airspace and as such needs to be finished as soon as possible. The paper is based on the current state-of-the-art in the field of drones and the development of the integration of drones’ operation into airspace. Options considered are based on analysing existing solutions in Europe and in the world, and the development of regulations leading to the current draft of U-space legislation. The paper presents two main possibilities of connections between U-space stakeholders and sets out eight criteria according to which both options are compared. This comparison results in considering feasibility for both options, but the one where the CIS plays a central role through which all information flows is evaluated as better

CONVERSION OF COMBUSTION ENGINE TO RUN ON NATURAL GAS

katedra: KVM; přílohy: 1 x CD-ROM 4 X výkres; rozsah: 65 s. (13 627 slov)This thesis deals with the conversion of Škoda 1.6 MPI engine to run on compressed natural gas (CNG), with a focus on design fuel system. The paper describes other necessary design adjustments for the actual operation of the natural gas engine, such as modifying the intake manifold, modifying the intake and exhaust valves and valve seats, selection pressure regulator, selection of appropriate injectors and the suchlike. Because lower performance of natural gas engines is one of the important issues, there is shown possible adjustment of piston to enlarge compression ratio of the engine and thus increase its performance. The next section of the paper performs a calculation performance and operating characteristics of the engine using program TLAK macro.xls made at the Department of Motor Vehicles and the Technical University of Liberec. The paper also gives a proposal for the calculation of the engine using program GT-Power.Tato diplomová práce pojednává o přestavbě motoru Škoda 1,6 MPI pro provoz na stlačený zemní plyn (CNG) se zaměřením na konstrukční řešení palivového systému.

Diverse tick-borne microorganisms identified in free-living ungulates in Slovakia

Background: Free-living ungulates are hosts of ixodid ticks and reservoirs of tick-borne microorganisms in central Europe and many regions around the world. Tissue samples and engorged ticks were obtained from roe deer, red deer, fallow deer, mouflon, and wild boar hunted in deciduous forests of south-western Slovakia. DNA isolated from these samples was screened for the presence of tick-borne microorganisms by PCR-based methods. Results: Ticks were found to infest all examined ungulate species. The principal infesting tick was Ixodes ricinus, identified on 90.4% of wildlife, and included all developmental stages. Larvae and nymphs of Haemaphysalis concinna were feeding on 9.6% of wildlife. Two specimens of Dermacentor reticulatus were also identified. Ungulates were positive for A. phagocytophilum and Theileria spp. Anaplasma phagocytophilum was found to infect 96.1% of cervids, 88.9% of mouflon, and 28.2% of wild boar, whereas Theileria spp. was detected only in cervids (94.6%). Importantly, a high rate of cervids (89%) showed mixed infections with both these microorganisms. In addition to A. phagocytophilum and Theileria spp., Rickettsia helvetica, R. monacensis, unidentified Rickettsia sp., Coxiella burnetii, "Candidatus Neoehrlichia mikurensis", Borrelia burgdorferi (s.l.) and Babesia venatorum were identified in engorged I. ricinus. Furthermore, A. phagocytophilum, Babesia spp. and Theileria spp. were detected in engorged H. concinna. Analysis of 16S rRNA and groEL gene sequences revealed the presence of five and two A. phagocytophilum variants, respectively, among which sequences identified in wild boar showed identity to the sequence of the causative agent of human granulocytic anaplasmosis (HGA). Phylogenetic analysis of Theileria 18S rRNA gene sequences amplified from cervids and engorged I. ricinus ticks segregated jointly with sequences of T. capreoli isolates into a moderately supported monophyletic clade. Conclusions: The findings indicate that free-living ungulates are reservoirs for A. phagocytophilum and Theileria spp. and engorged ixodid ticks attached to ungulates are good sentinels for the presence of agents of public and veterinary concern. Further analyses of the A. phagocytophilum genetic variants and Theileria species and their associations with vector ticks and free-living ungulates are required.Fil: Kazimírová, Mária.

A review on the eco-epidemiology and clinical management of human granulocytic anaplasmosis and its agent in Europe

Anaplasma phagocytophilum is the agent of tick-borne fever, equine, canine and human granulocytic anaplasmosis. The common route of A. phagocytophilum transmission is through a tick bite, the main vector in Europe being Ixodes ricinus. Despite the apparently ubiquitous presence of the pathogen A. phagocytophilum in ticks and various wild and domestic animals from Europe, up to date published clinical cases of human granulocytic anaplasmosis (HGA) remain rare compared to the worldwide status. It is unclear if this reflects the epidemiological dynamics of the human infection in Europe or if the disease is underdiagnosed or underreported. Epidemiologic studies in Europe have suggested an increased occupational risk of infection for forestry workers, hunters, veterinarians, and farmers with a tick-bite history and living in endemic areas. Although the overall genetic diversity of A. phagocytophilum in Europe is higher than in the USA, the strains responsible for the human infections are related on both continents. However, the study of the genetic variability and assessment of the difference of pathogenicity and infectivity between strains to various hosts has been insufficiently explored to date. Most of the European HGA cases presented as a mild infection, common clinical signs being pyrexia, headache, myalgia and arthralgia. The diagnosis of HGA in the USA was recommended to be based on clinical signs and the patient’s history and later confirmed using specialized laboratory tests. However, in Europe since the majority of cases are presenting as mild infection, laboratory tests may be performed before the treatment in order to avoid antibiotic overuse. The drug of choice for HGA is doxycycline and because of potential for serious complication the treatment should be instituted on clinical suspicion alone
