The effect of wetting in the density and volume of seeds of barley, rye and two cultivars of wheat was determined. Two levels of wetting were used: (i) 6 h wetting close to the end of imbibition; (ii) 24 h wetting close to the beginning of germinatio

Deformation curves in uniaxial compression of raw potato tuber were analyzed at Nicola and Saturna varieties. In the first part of deformation (time 1 min), some part of specimens were loaded by electric field simulating simultaneous measurement of t

The permittivity of potato tissue was studied during uniaxial compression of cylindrical specimens prepared from two early varieties. Both the real and the imaginary permitivity components were determined repeatedly during the loading and unloading t

The internal structures of agricultural products change substantially in the course of the products deformation. One of the main changes in this process is the loss of the water content and water solutions generally due to the squeezing out of the ce

The new CPEM (cooked potato effective mass) method was used to study the sloughing of a potato variety grown in two successive years in six regimes given by different levels and forms of fertilisation and irrigation. The sloughing process is characte

Potato tuber specimens of two varieties (Nicola and Saturna) were deformed in a compression loading/unloading test. The tuber complex permittivity spectrum at frequencies 0.1-500 kHz was measured repeatedly during the deformation. The results show th

The Agria potato tubers were grown in 2005 in cultivation regimes involving different irrigation and fertilisation levels and forms. The impact induced tuber damage was simulated dynamically by an impact pendulum test and studied with the aim to dete

Four classes of peptidolytic enzymes were described in insects. Many authors have found predominant activity belonging to trypsin-like and chymotrypsin-like activity. By the use specific chromogenic substrates and hemoglobin we have determined enzyme
