URTICA DIOICA AND ZINGIBER OFFICINALE EXTRACTS WITH AGRO-FOOD AND PHARMACEUTICAL APPLICATIONS

The present work is an attempt to highlight the effect of aqueous extracts of Urtica dioica (nettle) and Zingiber officinale (ginger) in in vitro studies. The insights from current research would be helpful to have an overview of the antioxidant potential of nettle and ginger and provide direction for optimization and development of these extracts for phytosanitary applications against vegetable diseases as well as preservation role in the agrifood industry. The antioxidant activities of nettle and ginger are found to be protective for vegetables diseases with Alternaria solani. The study also highlighted the potential of a green corrosion inhibitor for metal food packaging

ASPECTS REGARDING THE EFFECTS OF THE COVID-19 PANDEMIC ON THE 10 – 11-YEAR-OLD CHILDREN'S ACTIVE MOTOR, DIETARY, AND PSYCHOLOGICAL BEHAVIOR

Child obesity has become a phenomenon that is increasingly difficult to counteract because of their lifestyle and diet. The extra weight leads to, besides physical disorders, such as high cholesterol and diabetes, a series of psychological disorders represented by the lack of self-confidence and depression. Physical activity was strongly affected during the COVID-19 pandemic because of the imposed restrictions. The children had to study online classes a large portion of their time, which has contributed to a significant increase in the hours they have spent in front of a computer. The objective of this study was to emphasize the effects of the Coronavirus pandemic on the relation between the active motor behavior, the dietary behavior, and the psychological behavior in 10-11-year-old children of Bacau, Romania. This research is an observational study conducted by identifying, assessing, and establishing certain correlations between the aforementioned factors, based on questionnaires filled by the children's mothers. Of the main statistical markers, the following were used: the Cronbach's alpha fidelity index, and the correlation coefficients, in order to establish the validity of the questionnaires, and the significance level of the correlations between the studied aspects

WHEAT FLOUR HUMIDITY VARIATION WITH UV-VIS RADIATION DOSE REVEALED BY SPECTRAL AND CHEMOMETRIC STUDIES

The cells’ exposure to UV radiation induces mutations of the cellular components by its action on DNA, protein synthesis and enzymatic activities. Different varieties of wheat flour were treated with UV-B, UV-A, Vis radiation and compared with untreated samples. The IR spectra for these components were recorded with a Bruker FTIR spectrophotometer using an ATR method, at 4 cm-1 resolution. The paper proposes a comparative study of unmaturing flour behavior under UV-Vis and natural radiations in order to observe the physico-chemical changing by FTIR spectroscopy. At small doses of irradiation (up to 2 h) the humidity of the samples decreases and then it significantly increases, most pronounced in Gruia’s case where the humidity is reaching 74.4% of the initial value. Middle infrared spectral studies reveal an inverse weak linear correlation between Amide I region (1650 cm-1) (R-squared value: -0.3168) and an inverse medium linear correlation assigned to area alcohol O-H band at 3290 cm-1 (R-squared value: -0.6064) with the irradiation dose variables. Strong direct linear correlations confirmed by R-squared value: 0.7835 are found between alcohol O-H band at 3290 cm-1 and humidity percentage parameter

ANALYSIS OF SEASONAL VARIATION ON DEGREE OF CONTAMINATION WITH HEAVY METALS IN AARJATE VILLAGE, MOROCCO. AN INDEX APPROACH

Water samples from wells and samples from soil nearby them were taken during dry (June-September 2013) and wet (December 2013, January - February 2014) seasons and concentrations of Cd, Cu, Mn, Ni, Pb and Zn were determined. Contamination Factor for each heavy metal and Nemerow pollution index were calculated showing a decrease in contamination degree from summer to winter for soil and an increase in case of groundwater. Vertical transfer of pollutants from top soil to groundwater was assessed using Hierarchical Cluster Analysis, significant correlations between concentrations and composition of soil being found. In case of Ni, the variables corresponding to the concentrations from soil and groundwater were part of the same cluster, in both seasons, the distribution maps of concentrations confirming the pattern of transfer
