Abstract:

For all the European agrifood establishments from the year 2005 it became mandatory the Regulation EC 178/2002 which obliges them to implement an internal system for tracking and tracing (T&T) of the products; the Regulations that has introduced an ‘obligatory route’ that consists of the construction of the ‘certified historic’ of a food or an ingredient along the supply chain. The Regulation concerns all food companies and in particular those in which there are different actors that contribute to obtaining the final product as in the case of the supply chain of olive oil.

Informatics with modern technology allows us to provide the company with a software solution, usable as a web application, everything housed on a system cloud server. The project goal was to implement a WebApplication based on Cloud Platform and centralize all information about to the context of the production of olive oil.
The results showed that the centralization of data provided by the software in question permit the various figures of the supply chain of olive oil to collaborate in an environment where you get all the information in real time. The system implements algorithms that provide notification messages that indicate if there are any delays in production/processing in terms of quality of the olive oil sought.
The operators and final customer will be equipped with an APP free for smartphones, which allow you to detect in a simple and immediate all data (in synchronize with the cloud system) and to get the product TRACEABILITY.

Abstract:

The European Union adopted a decision to achieve by 2020 at least 20% reduction in greenhouse gas emissions. To fulfill this task, the EU proposed in 2020 binding targets – further improve energy efficiency by 20%, achieving a 20% share of renewable energy and a 10% share of biofuels in the fuel market. One of the most widely used biofuel in the automotive industry is bioethanol. Bioethanol can be used on low-percentage blending into petrol, which is governed by European Directive 2003/30/EC, and on high-blend bioethanol mixture, particularly E85 consists of 85% bioethanol and 15% petrol BA95. But in recent years, increasingly demonstrating opinions, that biofuels do not produce nearly as much effect as was propagated. This paper deals with the concentration of water in the engine oil with using biofuel E85. The water in the engineoil significantly affects its parameters (especially viscosity). How measurement results demonstrated the use of bioethanol in the fuel increases the concentration of water in the engine oil.

Abstract:

The European Union aims to promote the use of biofuels and thus set a commitment to the expansion of biofuels in transport. Biofuels replace fossil fuels mainly in part, the creation of biodiesel. For gasoline engines, the most widely used biofuel is E85, a fuel containing 85% ethanol and 15% gasoline. The more bio-components are contained in a fuel, the more oil filling the combustion engine suffers. Therefore, in this paper, a comparison of the properties of oil filling when using fossil fuels (currently contains a small amount of the fuel ethanol) and the E85 biofuel is provided. The cars Saab 95 and 93 are monitored, namely the motors B235 R, B207 L, and B205 L. For each car, the total of 10 samples of engine oil were taken. One part of the samples was collected during operation of the internal combustion engine on the biofuel E85 and the second during operation of the internal combustion engine on the fossil fuel BA95. Both vehicles used the same engine oil, Mobil 1 0W-40, for lubrication of the internal combustion engine. The analyses of the engine oil are focused on the evaluation of the kinematic viscosity and density at 40 and 100°C.

Abstract:

An  adhesive  bonding  technology  is  a  prospective  bonding  technology  of  diverse materials.  Namely the research in the  sphere of the degradation aspects affecting the adhesive bond  during  the  technical  life  of  the  adhesive  bonded  complex  is  essential.  Mineral  and industrial fertilisers can be included as significant degradation agents. The aim of the research was to find out the relevant knowledge in the sphere of the degradation of the adhesive bonds placed in the water bath, the oil bath and the solution of the mineral and industrial  fertilisers.  The  experiment’s  results  bring  knowledge  for  producers  of  agricultural machines  introducing  adhesive  bonding  technology  into  their  production  programme.  Two-component constructional epoxy adhesives were tested which were placed into the water bath, the  oil  bath  and  the  solution  of  mineral  and  industrial  fertilisers.  Some  agents  caused  such changes in the adhesive that the adhesive bond strength decreased to zero value already after ⁹0 days.  Significant  changes  of  the  adhesive  bond  strength  occurred  in  the  interval  ¹⁵–⁴⁵  days depending on the adhesive and agents. The strength decrease was connected with the change of a  failure  area  from  cohesive  one  to  combined  and  then  to  adhesive  one.  The  research  showed that it came to diffuse seepage and to a partial corrosion of the adhesive bonded steel samples.
