The purpose of the research paper was to manage the dry fractioning operation and find out a new solution for it?s effectiveness. Therefore, based on previous studies of the authors related to dry fractioning in centrifugal field on complex lipid mixture, the correlation between the operating parameters (time ? temperature ? centrifugal speed) and physic ? chemical parameters can be done through the principal component analysis (PCA). Starting from these considerations and from the fact that the pork lard is a com...

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...

Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices. This paper proposes the PWM control of the laboratory bell furnace with utilization of PI controller. The paper presents the PI control algorithm modified in order to regulate the power of furnace. The control ...

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...
