AB  - Intensified oil exploitation accompanied with frequent oil spills having a detrimental impact on ecosystems are seeking efficient, environmentally and economically feasible solutions. In an attempt to develop an efficient, reusable, biodegradable and cheap sorbent for oil clean-up non-woven sorbents based on recycled jute post-industrial textile waste were fabricated. The influence of area density of non-woven sorbents and hydrophobicity of fibers on overall oil sorption performance was the focus of this research. All sorbents showed a good reusability after five sorption cycles and buoyancy in water even after 24 h independently of sorbent structure. The area density of sorbents and viscosity of studied oils (crude oil, diesel oil and two types of motor oils) highly affected the oil sorption capacity and oil retention. The sorbent with the lowest area density exhibited the best oil sorption performance. The esterification of jute with stearic fatty acid contributed to decrease in water uptake of sorbents but also to negligible change of oil sorption behavior indicating that the structure of the sorbent in this case plays a crucial role.

AB  - The principle of rotating sizing machines based on a division of the fruits of various geometrical characteristics of the gaps of the same dimensions are typical for any given class separately. The classes are deployed from the smallest to the largest in the direction of rotation of the disk, and arc sizing board can be mixed performance, as slope metering gape and step metering gape. This paper discusses the movement of fruit in relation of their speed, and analyzes the model for determining the capacity of rotating sizing machines for different kinds of fresh fruit and deep-frozen raspberries. Mass flow calibrator or capacity for fruits tested in this paper are similar to those obtained in some other known methods. Calibrated mass flow is proportional to the weight of fruit and fruit in inverse proportion to the diameter of treated fruit.
AB  - Princip rada rotirajućih diskosnih kalibratora zasniva se na odvajanju plodova različitih geometrijskih karakteristika kroz zazore odgovarajućih dimenzija karakterističnih za svaku zadatu klasu posebno. Klase su raspoređene od najmanje do najveće u smeru rotacije diska, a lučna kalibraciona pregrada može biti dvojake izvedbe, sa konstantno opadajućom širinom zazora i sa kaskadnom širinom. U ovom radu se razmatra kretanje plodova sa aspekta njihove brzine, i analizira model za određivanje kapaciteta rotacionih diskosnih kalibratora za različite vrste svežeg voća kao i za duboko zamrznutu malinu. Maseni protoci odnosno kapaciteti kalibratora za ispitane vrste voća u radu su približni onim koji su dobijeni nekim drugim poznatim metodama. Maseni protok kalibriranog voća srazmeran je masi i obrnuto srazmeran prečniku plodova za tretirano voće.
