The paper covers theoretical substantiation of the rational parameters of a horizontal conveyer-cleaner of sugar beets providing their minimum loss during process performance. The procedure of conducting experimental investigations on the developed design of a horizontal conveyer-cleaner of root crops in configuration with a root crop harvester is presented. The results of the experimental research on determining root crop loss, damage and impurity depending on the design and kinematic parameters of a cleaner are provided. In order to choose the rational parameters, specific recommendations are provided.

The aim of the research endeavour was to evaluate the powder properties of freeze dried and spray dried beet-root powders.The physical, proximate, color and functional properties such as water activity, wettability, solubility and hygroscopicity were studied. From the comparative analysis between freeze and spray dried beet root powder, better results were found for freeze-dried samples in terms of color, wettability and hygroscopicity. Freeze-dried samples required a longer amount of time to obtain into powder form as compared to spray dried samples. Whereas the solubility and water activity values were found slightly higher in spray dried samples as compared to freeze dried samples. The proximate analysis, such as crude fiber, crude fat, ash and carbohydrate values recorded better result for freeze dried samples as compared to spray dried samples. It can be concluded from this study that the beet root, when dried in the freeze drying process, has better results as compared to the spray drying process.

Onion processing waste (OPW) was dried in a convective hot-air laboratory scale dryer at 50, 60, 70 and 80ºC. The effect of drying temperature on the drying characteristics and on the total phenolic and total flavonoid content of dried samples was determined. Three mostly used models were applied for fitting the experimental drying curves. The results indicated that the constant rate-drying period was not observed and that the logarithmic model was the most suitable for fitting the experimental drying kinetic data. The drying temperature significantly affected the total phenolic and total flavonoid content of dried OPW. The values of effective diffusivity were calculated and the determined value of activation energy was 28.05 kJ/mol.

Remote Sensing (RS) provides the best ways to monitor temporal changes and to understand land use dynamics. Remote sensing analysis can be further enhanced when community perception regarding major drivers of change is integrated. The present study was an attempt to assess the land use land cover changes in the Ishkoman watershed in the Ghizer district. The study explored Landsat-5 and Landsat-8 images to assess the LULC dynamics from 1998 to 2018, and also used questionnaires for community perception regarding LULC changes in the past two decades. Supervised classification was used to monitor changes between 1998 and 2018 and the maximum likelihood technique was used to categorize the pixels into six classes: vegetation/forest area, bare rocks, water bodies, glaciers/snow area, rivers, water, and agriculture. Regarding the questionnaires, the correlation matrix and regression models were developed between independent variables (population, land type cleared, and extra land required for new family members) and dependent variables (land use dynamics factors and socio-economic variables). The results showed that all six land cover classes have shown temporal changes between 1998-2018 and the most significant change was observed in forests and pastures (which decreased from 18.7% to 5.9 %). Similarly, glaciers, water, rivers, and agriculture have changed from 13.1, 6.5, 9.3, 1.5 to 15.8, 4.0, 11.32, 3.1, respectively between 1998-2018. The largest change was observed in bare rocks which increased from 50.2 % to 60.06%. Moreover, temporal NDVI analysis showed a decrease in vegetation cover (conversion to bare rocks) between 1998-2018. The questionnaire results revealed that the highest correlation was shown between population increase and decrease in crop production (R2 = -0.348), whereas the lowest correlation was found in population increase and population access to bus stops (R2 = -0.167). Similarly, the highest correlation was found between access to roads and markets (R2 = 0.349) and dependent variable (land type cleared), whereas the lowest correlobserved in access to water resources (R2 = -0.021). The study concluded that land use land cover has been significantly changed from 1998 to 2018 in the Ishkoman Watershed. The study suggested more in-depth research to examine land use land cover changes at finer scales by using high resolution satellite imagery, and conducting details surveys regarding the underlying anthropogenic causes of land use dynamics.

Doogh is an Iranian drink produced from yoghurt. Swelling is an undesirable change of Doogh, usually caused by Kluyveromyces marxianus. The aim of this study was the investigation of the effect of the thermosonication process on Kluyveromyces marxianus survival as well as the determination of the impact of this process on other quality parameters (viscosity and serum separation). For this reason, Kluyveromyces marxianus (about 105 cells per milliliter) inoculated into Doogh samples, thereafter samples being exposed to various thermosonication process conditions. Results showed that the thermosonication operation resulted in the reduction of the yeast population of Doogh samples (p <0.05). The lowest yeast population was observed in the sample subjected to acoustic density=1w/ml, T= 60°C and t=30min (1.7±0.01CFU/ml). Other operation conditions also had impact on yeast survival (p <0.05). Thermosonication also had significant effects on the viscosity of the Doogh samples. Serum separation of samples was also measured and observation implied changing serum separation magnitude between different samples in comparison with the control sample (p <0.05).

The study was intended to identify species preferences, the relationship between livelihood status and tree planting, and the major tree growing patterns of smallholder subsistence farmers in rural Ethiopia. Data was collected through household interviews and the total enumeration of all tree species on respondents’ landholdings. A total of 23 tree species were recorded integrated within the farming landscape as boundary plantings, scattered on crop fields, around the homestead and woodlots. There was a significant difference in the mean number of trees per household across the three wealth classes. Among the three wealth classes, the medium wealth category households have a relatively higher number of tree species than rich and poor households (p<0.05). Considering the ever-increasing population and the resulting demand for construction poles, fuelwood, household utensils, farm implements, and the fast-growing performance of the species, Eucalyptus camaldulensis Dehnh. was the first preferred tree species to households for planting. Tree integration in the farming landscape should be recognized since it will be invaluable in developing plans for agroforestry interventions. However, exotic tree species have dominated the status of indigenous tree species. Then, there should be a continuous and detailed extension system to upgrade the traditional management system and the tree selection to be integrated.

Nearly 50% of Romanian households use wood as a source of heating. A series of contradicting official reports regarding the demand and supply of firewood in Romania indicates that the consumed volume is higher than the available quantity. This study aims to characterise the dynamics of the firewood market and shed light on the officially reported figures. We analysed certain variables and their influence on firewood demand for six consecutive years. The demand was significantly higher than the supply and was strongly correlated with the unemployment rate. This socio-economic facet leads us to believe that abruptly diminishing fuelwood consumption is an unrealistic policy objective of the authorities.

The purpose of this study was to analyze some chemical elements and to determine the content of total phenols and pigments in the brown seaweed Cystoseira barbata from Rusalka Cape near the Black Sea. In addition, the antioxidant potential of this algae was also evaluated by four methods based on different mechanisms. The obtained results were compared with other scientific studies related to inorganic and organized compositions of Cystoseira barbata from different marine regions.It was found that the seaweed from Rusalka Cape contained high values of manganese, chromium and boron and a high concentration of carotenoids. Therefore, this seaweed was evaluated as a source of microelements, carotenoids and antioxidants.
