This article presents the a comparison study between two enzymes: lipase and carboxylesterase, considering the influence on the rheological parameters of the dough obtained from wheat flour. For determining the activity of the enzymes, there were performed the following analysis: the determination of the fat content using Soxhlet method and the determination of rheological parameters of the dough using the alveographic method. The Soxhlet method is based on repeated extraction with ethyl ether or petroleum ether o...

This article presents the influence of beta-amilase on 3 types of flour: white, whole and brown flour used in the baking industry. In order to determine the activity of the enzyme, the following analysis were done: the falling number using Perten Instruments FN 1310 and the rheological parameters of the dough using the alveographic method. The falling index indirectly measures the activity of enzymes, rapidly jellifying the aqueous suspension of flour which is introduced in a boiling water bath and it measures the...

This study aimed to establish if the dried shredded leaves of Acer platanoides could represent an adequate food for earthworm Eisenia fetida (Savigny 1826) (red wiggler worm). The study was carried out in laboratory conditions and its aims were to determine the influence of this food on three biological parameters of earthworm Eisenia fetida (survival, weight, and prolificacy), and to reveal the changes appearing into the soil in the presence of this earthworm species, fed or not with shredded leaves of Acer plata...

In the era of the increasingly implementation of renewable energy sources in the electrical energy supply, the expansion of a sustainable energy industry must be promoted the resulting increase in storage requirements. The Gravity Hydro Power Tower Energy Storage (GHPTES) is an innovative hydraulic energy storage system based on pumped storage technology. It consists of a vertical cylindrical cavity, filled with water, in which moves an overload piston from steel at smaller storage systems or from rock at large st...

The aim of our proposals for soil sampling regarding mesofauna study in soils from greenhouses or polytunnels is motivated by the high soil heterogeneity and large variability of easy exchangeable soil properties such as water content, soluble salts distribution especially under drip irrigation and local fertilization. The intensive technology for growing vegetables or flowers, high irrigation requirements and the high soil moisture favors, in short time the degradation of morphological, physical, chemical propert...

Due to the flow behavior complexity, the calculation of local head losses needs to be based on experimental results. Although there is great literature regarding the study of valves, and a part of it contains detailed results of local head loss too, these values are always related to a specific manufacturer. This means that for accurate design it is recommended to know the specific head loss exactly for the used device. In the present paper the conception and building of an experimental stand for measurement of lo...

Space weather can be monitored from the ground (astronomic/astrophysics observations and geomagnetic observatories) and from space (satellite data). Optical instruments (telescopes on the ground) recording the number of sun spots, as well as to viewing aurora, but these observations are affected by the weather from Earth's atmosphere. Observation from space does not have such a limitation. In the last years,satellites and spacecraft have monitoring the space weather. Through cooperationbetween European Space Agenc...

For a balanced life, milk and dairy products occupy an important place in the gastronomic culture of each country and are highly appreciate for their nutritional values. Cheese, as the most consumed milk ? derived product, it turned out to be a food product rich in nutrients that was the subject of numerous studies because of its contribution to nutrition and health. There are a very large number of cheese types,with different composition, due to many variations in production process, and that's why it is difficul...

Energy efficiency is a key factor of today?s engineering practice. Water and wastewater systems (made up of supply and disposal networks, treatment plants etc.) often contain under pressure sections. Their energy efficiency strongly depends on the accuracy of the head loss evaluation including local head loss. In these systems a great amount of local head loss is given by different valves. Gate valves and check valves are being widely used in water and wastewater systems, therefore this article focuses especially ...

The article provides a brief description of the concept human-machine interface for the interactive touch control panel of the mobile cone crusher. A software implementation of an automated cone crusher control system is proposed that allows to integrate a set of interconnected technological units in the control of one hardware and technical units in the controller and human-machine interface on the touch panel in the operator station. A human-machine interface was implemented, based on a set of technical, informa...

Carrying out scientific experiments and field observations requires systematization, coordinated storage and possibility of online analytical processing of primary data to obtain consistent results and to discovery new knowledge. The article presents an approach to building a model-driven system based on the software platform of primary data collection and analysis. An approach to the constructing the control model of the data consolidation system based on the analysis of data description in the context of the sta...
