Jednym z roślinnych odpadów poprodukcyjnych, generowanych przez zakłady Herbapol w Białymstoku, są drobnoziarniste odpady pokrzywy powstające podczas ich segregowania i pakowania. W artykule przedstawiono wyniki badań wpływu parametrów technologicznych procesu granulowania bezciśnieniowego na kształt granulatu z odpadów pokrzywy. Proces granulowania przeprowadzono z wykorzystaniem nowatorskiego układu...
Relation between the shape and course of lactation curve and production traits of Polish Holstein-Friesian and Montbeliarde cows. The aim of the study was to examine the relation between shape and course of lactation curve and production traits of Polish Holstein-Friesian and Montbeliarde cows kept under various production systems. The production parameters were based on cows records developed by...
Cherry laurel (Prunus laurocerasus) is an important wild edible fruits naturally grown in black sea region in Turkey. Shape attributes of twenty-one cherry laurel accessions were determined both descriptively and based on elliptic Fourier analysis first time in the literature. In the semantic evaluation, shape of most of the accessions was near to sphere. But, the results of the descriptive data showed...
Computer-aiding of mathematical modeling of the carrot (Daucus carota L.) root shape. The developed method refers to computer aided mathematical modeling of the carrot root. The Bézier curves were used in mathematical model for description of the carrot root shape. Two smoothly connected Bézier curves described half of longitudinal contour of carrot root cross section. After rotation of these curves,...
It is proposed that it is possible to identify some of the problems that had to be solved in the course of evolution for the red blood cell (RBC) to achieve its present day effectiveness, by studying the behavior of systems featuring different, partial characteristics of its membrane. The appropriateness of the RBC volume to membrane area ratio for its circulation in the blood is interpreted on the...
W pracy przedstawiono wyniki badań wpływu wilgotności surowca na wybrane właściwości fizyczne ziarna. Użyte do badań ziarno pochodziło z doświadczeń Katedry Agrotechnologii i Zarządzania Produkcją Roślinną Uniwersytetu Warmińsko-Mazurskiego nad wpływem dawki azotu na wysokość i jakość plonu. Badaniom poddano dwie odmiany: populacyjną Amilo i mieszańcową Esprit. Przed doświadczeniem określono wilgotność,...
Badano wpływ długości czasu oświetlenia oraz natężenia światła na wielkość plonu oraz kształt i masę owocników wybranych odmian boczniaka. Podjęto również próbę ustalenia czy można stosować zamiennie światło o wysokim natężeniu, przy krótkim czasie oświetlenia i światło o mniejszym natężeniu przez dłuższy okres czasu. Jednostki uprawowe boczniaka po okresie inkubacji przeniesiono do pomieszczenia...
Background. The purpose of this study was to identify mathematical equations describing changes in a flatfish body shape along its longitudinal axis. The initial function for the description of a cross-section contour is the ellipse equation including a factor deforming the symmetry with respect to one of axes. Such equations may find their use in fisheries engineering and food-fish processing. Materials...
The article presents the attempt to establish connections between the shape of cones and the weight, number and colour of seeds coming from one stand. The author suggested choosing pine (Pinus sylvestris) seeds of the best cultivation characteristics before extraction, paying attention to the shape of cones, and after extraction basing on the weight and colour of seeds. In addition, the author studies...
