A COMPARISON OF CONVENTIONAL AND NOVEL CASTOR OIL RECOVERY METHODS
Castor (Ricinus communis L.) is cultivated as a non-edible oilseed crop across tropical, sub-tropical, and temperate regions, often in areas with marginal soils. The castor oil recovery process usually involves primary seed preparation, oil recovery, and refining, with variations in the order of operations. The recovery methods include conven...

EXTRACTION OF RESIDUAL OIL FROM FODDER RADISH SEED PRESS CAKE
The residual oil extracted from a press cake, a by-product of fodder radish seed screw pressing, underwent extraction using n-hexane as an extracting solvent. The influence of various process parameters (solvent/press cake ratio: 3–10 mL/g, temperature: 20–70 °C, and processing time: 1–5 min) on the residual fodder radis...

EXAMINATION OF THE QUALITY OF GOAT CHEESE IN A SACK
Goat cheese in a sack is a traditional Herzegovinian product of extreme specificity, both in production technology and in the properties of the final product. The main characteristic of cheese in a sack is anaerobic ripening inside a bag made of lamb skin (mixture), which is how the cheese got its name. The aim of this work is to examine the ...

ENHANCEMENT OF PHOTODETECTION PARAMETERS USING FLUORINE AND SILVER CO-DOPING IN ZNO
This study aims to dope silver (Ag) and fluorine (F) in zinc oxide (ZnO) for the improvement of photoresponse properties in ZnO since previous reports confirmed improvement of these properties using individual doping of F and Ag. The F-doped ZnO (FZO) and F and Ag co-doped ZnO (FAZO) nanorods were synthesized using a modified hydrothermal met...
