Summary: This study aimed to compare the effect of lactic acid and ethanol extraction methods on the phenolic compounds and antioxidant activity of propolis. The results showed that the lactic acid-based solution had similar phenolic compound content to the ethanol-based solution at a propolis concentration of 10%, but the lactic acid solution had significantly higher antioxidant activity. These findings suggest that lactic acid can be used as an alternative to ethanol for propolis extraction.

Summary: This study investigates the effects of endogenous polyamines (PAs) on the antioxidant system in alfalfa under drought stress. It was found that high activity of arginine decarboxylase (ADC) and S-adenosylmethionine decarboxylase (SAMDC) promotes the conversion of putrescine (Put) to spermidine (Spd) and spermine (Spm), leading to increased accumulation of Spd and Spm and enhanced drought resistance in alfalfa.

Summary: The arsenite-humic acid binding process was studied using various techniques including Isothermal Titration Calorimetry, Dynamic Light Scattering, and Laser Doppler Electrophoresis. A model called MNIS was used to interpret the data, and it was found that hydrogen bonding was the dominant interaction type in the system. The binding process was exothermic and spontaneous, with pronounced binding affinity. The formation of arsenite-humic acid complexes at common soil pH values suggests a possible influence on increased mobility and reduced bioavailability of arsenic.

Summary: With the goal of enhancing the quality of the environment, urban green infrastructure (UGI) is an essential element in sustainable cities, and nature-based solutions (NBS) are being carried out as new infrastructure solutions that increase the resilience of cities. In this research, the hindrances and bottlenecks in implementing NBS, the effectiveness of current decision-making mechanisms in shaping cities with NBS, and the presence of binding policies promoting NBS were analyzed. The planned interventions and management strategies in Belgrade involve intensive urban green space management, urban planning, water management, ecological restoration, and creation of semi-natural water bodies and hydrographic networks. It is important to implement policies and incentives on national, regional, and local scales to encourage the usage of NBS in urban infrastructure development.

Summary: Road traffic accidents are a global public health issue, causing nearly 1.3 million deaths annually and numerous injuries. Predicting and preventing accidents on new road sections is challenging due to various subjective and objective factors. Artificial neural networks (ANN) have shown their effectiveness in predicting accidents using limited data sets. This study presents two ANN models to predict traffic accidents in Serbia and Bosnia and Herzegovina using easily determined objective factors. The models accurately predict the number and severity of accidents, showcasing the potential of ANN in transportation planning and decision-making.

Summary: Differential scanning calorimetry was used to investigate the kinetic properties and thermal characteristics of fresh pork meat proteins and osmotically dehydrated meat proteins. The activation energy, pre-exponential factor, and extent of conversion were discussed using differential Friedman and integral Ortega methods. The results showed different activation energy values for different meat proteins and indicated that osmotically dried meat proteins were partly unfolded. Understanding the nature of meat protein denaturation is important for developing meat product processing technology and achieving desired quality and nutritional value.
