Effect of nanomaterials on work safety
304-312Views:107Nowadays, due to their special properties, nanomaterials are gaining more and more interest and their industrial application is increasing. Their specific properties are mainly due to the fact that the main characteristics of nanomaterials are not always the same as the normal size range of the same material. While these materials fulfill an important new function in the industry, their interactions with the environment and biological organisms are becoming increasingly unpredictable, increasing uncertainty, for example, in their application to human safety. Due to the very rapid technological development, these substances have been used much earlier than the legal framework for their application could have developed, and therefore a binding regulation on the use of nanomaterials is currently not available. At this moment, the manufacturer of the nanomaterial is responsible for the safety of the products. Of course, owever, chemical safety legislation and standards provide an excellent basis for their management, but due to their specific properties, novelty and lack of knowledge of the mechanism of action, risk assessment can still be a challenge for the practitioner.

The New Type of Employment: the Specificity of the Platform Economy and Platform Work
75-90Views:213The industry value of the global platform economy exceeded 7 trillion US dollars by the end of the second decade of the 21st century. The income generated by the platform economy in the European Union produced an almost five-fold increase in the period between 2016-2020, as its volume increased from 3 billion euros to 14 billion euros. Nevertheless, due to the lack of global consensus and precedent, the delimitation of the platform business model and work, its legal regulation and verifiability and compliance, due to its innovative nature, are unresolved at the world and European level. The objective of the article is to define the conditions, rules and practical application of the platform economy and platform work, relying on international (English-language, mostly European) secondary information, thereby revealing the problems and difficulties, as well as discussing its advantages and disadvantages.

Liquidation of Public Procurement Due to Operative Regulations
1-8Views:112The aim of new Public Procurement law is to ensure the efficiency of appropriation public money. On new lwgal regulation public procurement procedure sbecome significantly faster and transparency and competition are increasing. Hence forward the rules of procedures under Europian Union limit won’t be standard. Innational pro curement procedures the rules are differentiated from estimate value. Important change in connection with valuation base dont he lowest price is succeeded by the method of proportion price and value.

Possibilities of the Reclamation of Wastewater in Small Abattoirs Combined with Rainwater Harvesting
115-125Views:64The purpose of the study is to review the extent to which waste water from small mobile slaughterhouses can be reclaimed along with the basic cases and the purpose for which this can be realized. Keeping the criteria of sustainability in mind, I identify the possible and at the same time reasonable combinations of technology, highlighting and presenting in more detail those that include the utilization of waste water and the utilization of rainwater. I will describe the limiting factors - site features, environmental protection and health regulations - which are decisive in which alternative can be chosen during a specific installation.

Sport Civic Society – Approaches and Facts
158-166Views:227After the change of regime in Hungary in 1989, the domestic civic sphere started to improve, and after numerous change in the legal regulation, currently the Act on Civic Organizations (Act 174/2011.) rules the operation of the sector before all, supplemented by additional legal background. The vital component of the new regulation is possibility of the appearance of the novel organizational form, the civic society, which is quite odd even considering the past and even on international level. The database enabling the statistical overview of the domestic nonprofits publish the end of 2019 provides no information on the data and operational features for this organizational form, which provides a thorough reason for the researcher to be interested in the topic and the organizations. Through the possible secondary data, a primary database of a lately done sports civic organization related research includes such basic data (even its sample height is small), which may be considered as a starting point at the examination of the specifications of the sports related civic societies.

The Relationship Between EHS and the REACH Regulation in Practice
128-133Views:111The European Union has enacted strict safety regulations on the usage of chemical substances. Not long ago the Hungarian Government has also enacted the 1907/2006/EK (REACH) regulation and 1272/2008/EK (CLP) regulation. With the acceptance of the decrees our knowledge and available information about chemicals has expanded, due to the reporting obligation. As a consequence the usage of hazardous chemical compounds will be safer for the people and the environment. With the access to the shared data, we will be able to make appropriate decisions despite lacking previous measurements of our own. My goal is to present the hazardous information profiles form the packages of the REACH and CLP, and their possible applications.

Vehicle Dynamics Simulation in Matlab/Simulink Environment
36-41Views:250In the following we are researching different methods of vehicle dynamics simulations. Starting from a simple two-wheeled vehicle model, we are showing ways to simulate the movement of vehicles with real suspensions on any surfaces. MATLAB, Simulink and Simscape provide very suitable resources for the above mentioned purposes. The benefits of such vehicle model become obvious because of the fact during the physics simulation we can access all the data we need to simulate any control algorithms for vehicles: in this article we are presenting a simple ABS control simulation.

Grants Rating Due to Operative Public Procurement Law and by Applicable Regulations
129-138Views:140The aim of new Public Procurement law is to ensure the efficiency of appropriation public money. On new legal regulation public procurement procedures become significantly faster and transparency and competition is increasing. The law entered into force on the first of November in 2015, but has been modified several times since then. A year ago, the National Parliament adopted the law on State Program Evaluation cover. The legislation aims to make the European Union resources for projects in an objective, transparent and independent from the interests of the operators assessment system.

Determination of the Differential Equations of a Dynamical System using Dual Description
41-48Views:38The paper deals with the description of a mathematical model of a mechanical system using the so-called energy-based approach. The model is created using both generalized displacements and generalized momenta. The latter prescription method is less common in practice, due to its complexity. The two ways are presented through the same example mechanical problem, and a control task is also solved with the help of a PID block.

Control Valve Testing During Operation
11-18Views:95The most commonly used control technology in building engineering is mixing. The purpose of the measurement is to find out what effects have the different control valve position combinations on the system. How the mixing efficiency changes in these cases.
