The technological model of operating area by the combined transport
The contribution deals with design technology service model using the combined transport.
It assesses the performance indicators in relation to price and quality of services provided and on this basis decides on the type of the transport. This is the decision-making processes, which should answer the question, whether used directly in road freight transport, direct rail freight transport or combined transport. In this contribution is the combined transport meant as a system between the conventional modes, which are transhipped goods from road vehicles to the rail cars or river boats
1-MethaneÂsulfonyl-1H-1,2,3-benzotriazole
The molÂecular geometry of the title compound, C7H7N3O2S, does not differ much from that of the previously reported 4-tolueneÂsulfonyl analogue. Unlike the latter compound, however, molÂecules of the title compound associate primarily via ĎâĎ stacking interÂactions of their benzene rings [centroidâcentroid distance = 3.5865â

], forming columnar stacks along the crystallographic 21 axes. These stacks are interÂconnected via weak CâHâŻO and CâHâŻN hydrogen bonds

It is focused on the processes of manufacturing, transport and storage. The first part is devoted to the analysis of a present situation from economic, market and political point of view, including the certifications interconnected. The second part is focused on particular processes in a logistic chain. It brings solutions to safety precautions during the manufacturing process, to optimization of the time needed for transport through the operational research methods, and to the allocation of storehouses and their security according to the TAPA certification. The last part deals with an optimal security in general. The conclusion resumes the knowledge of the whole work.Katedra technologie a ĹĂzenĂ dopravyDokonÄenĂĄ prĂĄce s ĂşspÄĹĄnou obhajobo

LOGISTIC TECHNOLOGY AND THE CITY LOGISTICS
Due to the increasing customer demands for quality traffic, increasing transport volumes and diverse range of possible technologies, logistics provides solutions in freight transport. This article focuses on logistics and information technology, market principles and new trends in the City logistics. Currently, it is important to solve the transport service in the City logistics, distribution models which are a guarantee of new opportunities for optimization of transport in urban areas
Measurement of HGB beer colloidal ageing and tannoid content development using complex turbidimetric analysis.
Measurements of HGB beers were carried out in concentrated and blended samples to analyse the chill haze and tannoid content development during the thermal forced ageing process. The measurements were performed by the method of complex turbidimetric analysis (CTA), based on a single instrumentation for beer chill haze determination in commercial bottles and polyvinylpyrrolidone/tannoid content titration of beer samples in usual reaction tubes. For illustration of the efficiency of the CTA method, the initial values of saturated ammonium sulphate precipitation limits (SASPL) and sensitive protein (SP) levels were determined, too. The CTA method confirmed enhanced colloidal stability of the blended HGB final product due to lower content of the high molecular weight haze active proteotannic complexes. An almost linear correlation between the chill haze and tannoid content development during beer ageing process, starting from some concentration threshold level after a certain lag time was revealed.The correlation between the tannoid content of HGB beer in blended and non blended state was found also linear. The CTA method can be effectively used for the evaluation and prediction of the HGB beer colloidal ageing process and diagnostics of the causes of production inhomogeneity.Measurements of HGB beers were carried out in concentrated and blended samples to analyse the chill haze and tannoid content development during the thermal forced ageing process.
