Roles of Logistics in Air Transportation

Article discusses about the implementation of logistics principles into the airport operations, the activities of air carriers and organization of airport processes. The airport is under review comprehensively, as an integrated logistics system, using elements of partnership collaboration (/Collaborate Decision Making /CDM) which is based on the common sharing of information by various elements of the system

Methodology of the Auditing Measures to Civil Airport Security and Protection

Airports similarly to other companies are certified in compliance with the International Standardization Organization (ISO) standards of products and services (series of ISO 9000 Standards regarding quality management), to coordinate the technical side of standardizatioon and normalization at an international scale. In order for the airports to meet the norms and the certification requirements as by the ISO they are liable to undergo strict audits of quality, as a rule, conducted by an independent auditing organization. Focus of the audits is primarily on airport operation economics and security. The article is an analysis into the methodology of the airport security audit processes and activities. Within the framework of planning, the sequence of steps is described in line with the principles and procedures of the Security Management System (SMS) and starndards established by the International Standardization Organization (ISO). The methodology of conducting airport security audit is developed in compliance with the national programme and international legislation standards (Annex 17) applicable to protection of civil aviation against acts of unlawful interference

Rezistencia vybraných odrôd pšenice ozimnej voči hubovým patogénom

The thesis was focused on the evaluation of the health status of winter wheat leaves. The experiments were established in the autumn of 2017 in the terrier area of Veľaty, the district of Trebišov, the county of Košice, in the south - east of Slovakia on my own fields. We tested five line wheat varieties. Evaluation of each experiments was performed three times. The least affected was the Genius type. On the other site the lowest level of fungal pathogen resistance was in the Bertold variety. Probably due to its unstaining. The Bodycek variety also appeared very well, but because it was not regulated by growth, it did not achieve the desired results. In the experimental fields, we focused primarily on the attack of wheat leaves by fungal pathogens that cause severe leaf diseases

Origin, distribution and transformation of authigenic carbonates in loessic soils

Processes of authigenic carbonates formation are component part of terrestrial biogeochemical cycle of carbon, which starts with co-accumulation of oxalic acid and Ca in Ca- oxalates. After plant decay are these biominerals slowly transformed under the influence of microbial processes into authigenic carbonates (calcites), depending on soil condition. The formation of authigenic calcites runs over in soil system where is rather high Ca and Mg concentration, presence of oxalomorphic plants and sufficient oxalotrophic stability of microorganisms. In addition to Ca-oxalates, Ca and Mg ions necessary for carbonate formation comes also from air (precipitation, dust), mineral weathering, subsurface water flow and decaying organic matter. The distribution pattern of authigenic calcites with depth, the size and shape of individual forms of calcites on loessic soils of SW Slovakia, as it is resulted from micromorphological study indicate that through the historical development of that soils as landscape units, soil water regime has played decisive role at vertical redistribution of forms (size, shape) of authigenic calcites. To this witness the depth of variation of needle calcite zones and horizons of micritic calcites occurrence depending on soil types (leaching). Needle shape calcite zones which approach closest to the soil surface, gradually coalescence to the horizons of micritic calcites with the depth. Micritic calcites are without, or with microsparitic domains. Our study concurrently support the ideas of their inorganic origin depending on evaporitic soil regime. This formations have its own historic dynamics on which depends also the preservation of calcaric nature of soils

Distribution pattern of dorsal root ganglion neurons synthesizing nitric oxide synthase in different animal species.

The main aim of the present review is to provide at first a little survey of the basic anatomical description of sensory ganglion neurons in relation to cell size, conduction velocity, thickness of myelin sheath and functional classification of their processes. In addition, we have focused to discuss current knowledge about the distribution pattern of neuronal nitric oxide synthase containing sensory neurons especially in the dorsal root ganglia in different animal species, hence, there is a large controversy in relation to interpretation of the results dealing with this interesting field of research.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Comparison of bicuspidization and Ross procedure in the treatment of unicuspid aortic valve disease in adults - Insight from the AVIATOR registry.

BACKGROUND: Unicuspid aortic valve (UAV) is the second most common underlying cause of aortic valve dysfunction in young adults after the bicuspid valve. The valve may be replaced (for example by pulmonary autograft) or repaired using the bicuspidization technique. The aim of our study was to compare short- and mid-term outcomes of Ross procedure with bicuspidization in patients with severe UAV dysfunction. METHODS: This was a multi-center retrospective observational cohort study comparing data from two dedicated Ross centers in the Czech Republic with bicuspidization outcomes provided by AVIATOR registry. As for the Ross group, only the patients with UAV were included. Primary endpoint was mid-term freedom from reintervention. Secondary endpoints were mid-term freedom from major adverse events, endocarditis and pacemaker implantation. RESULTS: Throughout the study period, 114 patients underwent the Ross procedure (years 2009-2020) and 126 patients underwent bicuspidization (years 2006-2019). The bicuspidization group was significantly younger and presented with a higher degree of dyspnea, a lower degree of aortic valve stenosis and more often with pure regurgitation. The primary endpoint occurred more frequently in the bicuspidization group than in the Ross group - 77.9 vs. 97.9 % at 5 years and 68.4 vs. 75.2 % at 10 years (p < 0.001). There was no difference in secondary endpoints. CONCLUSION: Ross procedure might offer a significantly lower mid-term risk of reintervention than bicuspidization in patients with UAV. Both procedures have comparable survival and risk of other short- and mid-term complications postoperatively
