Environmental negotiations are complex, and conveying the interaction between science policy in traditional teaching methods is challenging. To address this issue, innovative educational approaches like serious gaming role-playing games have emerged. These allow students to actively explore roles of different stakeholders environmental decision-making weigh for instance sometimes conflicting UN Sustainable Development Goals or other dilemmas. In work phosphorus negotiation game (P-Game)...
This study investigates the effects of ultrasound, in combination with chemical pretreatments, on quality attributes (total phenolic and carotenoid content, antioxidant activity (2,2-Diphenyl-1-picrylhydrazyl assay (DPPH)), ferric-reducing ability (FRAP), CIE L* a* b* color, non-enzymatic browning, rehydration ratio, textural morphological properties) red pepper subjected to drying (hot air or freeze drying). The fractional factorial design was used assess impact factors. global Derringer...
Abstract The paper presents results of an experimental investigation convective drying apples “var. Idared ,” potatoes Désirée ” and bananas Grand Nein in full recirculation laboratory‐scale dryer. experiments were conducted with cube‐shaped apple samples (side length 10 13 mm), potato chips (slice thickness 2 3 mm) banana cylinders 6 7 without pre‐treatment. experiment was at fully controlled air temperature (35–45–55°C), relative humidity (10–20–30%) velocity (1–1.5–2 m/s). Results are...
The aim of this research is to study the drying kinetics vacuum-dried and freeze-dried bee honey produced from two different varieties: Sunflower (Helianthus Annuus L.) Acacia (Robinia pseudo acacia L.). Vacuum treatments were carried out with samples? initial temperatures +25?C, ?20?C, ?40?C. Water content, total soluble solids, as well water activity fresh dried samples determined. Freeze-drying sample temperature ?40?C has resulted in shorter time (7-9 hours), moisture content (10%-12%),...
The aim of this research was to study the impact application technique and rate liquid starter fertilizer applied with a novel device on production corn. Starter in root system range freshly germinated plants ‘belt’ ‘point’ forms at different quantities (35, 50, 70, 100 L ha−1), which led intensive plant growth initial stages development. This adapted used for sowing same time. field trial set up two sites (two land types), conditions natural water regime soil during three vegetation seasons...
In this article is presented a thermodynamic analysis of cascade heat pump system designed for using in high-temperature heating systems. The own model was built by properties working fluids from the CoolProp base. to use ambient air as source with temperature t_amb= –20 °C and water up 70 °C. projected capacity 100 kW. coefficient performance (COP) due different mediums combinations cycles investigated. For best combination (mediums) sub-cooling, super-heating, pressure loss compressor’s...
The efficient utilization of waste from food industry is possible after thermal treatment the material. This should be economically feasible and compromise energy drying process. main goal this investigation to determine characteristics nectarine pomace as a industry. measurements were performed in an experimental dryer by combined conductive-convective method with disk-shaped samples 5, 7, 10 mm thickness 100 diameter at air temperatures 30, 40, 50, 60, 70?C, hot plate 70?C velocity 1.5...
This paper is the result of studying effects mechanical chamomile harvesting on yield and quality harvested chamomile. Chamomile (Chamomilla recutita (L) Rausch.) was at three time intervals (T1 - 240 days, T2 250 days T3 260 after sowing) by conceptually different harvesters. The results achieved indicate that harvester type significantly influences chamomile, whereas it not influenced time. Quality classified into four categories, observed greater number rotations a picking device...
Chemical protection is an indispensable agro-technical step in all segments of conventional agricultural production. The significance proper chemical large for the quality and yield cultivated culture, as financial costs that this measure has structure total costs. established technique control, monitoring work efficiency plant machines crop production numerous shortcomings. Different techniques precision agriculture enable us to record detect critical points various processes, so similar...
Drying kinetics and shrinkage of valerian plant root (Valeriana officinalis) was investigated during the convective hot air dryer with forced convection mode. Whole without cutting, cut into quarters, 2 mm thin slices were used in drying experiments. Initial moisture content roots 51.2±0.3% considered to be dry when they lost 68% fresh weight reached 10%. temperature set 40 50°C, velocity at 1 m/s. The relative humidity not controlled it depended on surroundings. experimental results fitted...
The paper analyzes the possibility and needs for use of specific types robots (mini unmanned aircraft with different designs designation UAVs) using in agriculture (agrodrone). year 2015 was proclaimed (Fortune Magazine, 2016) as increasing widespread UAVs various areas human activity, especially forestry (75% use). This is important large farm areas, where UAV has many useful functions a very cost-effective commercial application. Today, have increased sharply opportunities both civilian...
Large quantities of biomass result from fruit pruning, which is a required pomotechnical operation. Long-standing practice destroying and burning the pruning residues hard to change, although energy environmental indicators point importance proper exploitation. The aim this study show quantity value apple production, as well ways means their In Republicof Serbia, grown at 40,000 ha, with usual yield (3 t ha-1 residues). Upper heating for two varieties (Idared Jonagold), 42.36% moisture,...
