SIMULATION OF ULTRAFAST FREE ELECTRON DYNAMICS AND TIME-DEPENDENT REFLECTIVITY IN SKIN-LIKE TISSUE MEDIA UNDER SHORTPULSE LASER EXCITATION
In this study, we investigate the ultrafast dynamics of free electrons in skin-like tissue media, stimulated by laser pulses with durations between 50 fs and 100 fs. Our analysis is based on a rate-equation approach for the evolution of free electron density under different laser pulse durations. The simulated electron densities are then used...

SODIUM CHLORIDE SOLUTION TEST OF TI6AL4V IMPLANT SPECIMENS MANUFACTURED BY ADDITIVE TECHNOLOGY
Additive technology is a valuable process for medical implant manufacturing. The most common metallic material in this area is the Ti6Al4V alloy. The research aimed to learn the implant material behaviour in saltwater environments. During the sodium chloride test, material quantity and quality loss need to be evaluated. The corrosion resistance tes...

THE IMPORTANCE OF THE RELATIONS BETWEEN FAMILY AND SCHOOL (PEDAGOGUE/PSYCHOLOGIST)
The relationship between family and school is always a current topic. The cooperation between family and school implies a traditional spirit. Cooperation in the educational process previously referred primarily to the most basic relations between parents and the school. On the other hand, the partnership of the school (educator, pedagogue/psycholog...

EFFECT OF FREEZING ON PHYSICO-CHEMICAL, ANTIOXIDANT, AND SENSORY PROPERTIES OF HONEYDEW HONEY
Freezing food slows down the physico-chemical and biochemical reactions in food. In honey, freezing is primarily used to delay or halt crystallization, reduce viscosity, and preserve nutritional components. However, low temperatures may influence the physico-chemical, antioxidant, and sensory properties of honey. This study compares the properties...

IMPACT OF TREHALOSE-BASED CRYOPROTECTANT ON IMMOBILIZATION AND RELEASE OF LACTOBACILLUS PLANTARUM OBTAINED FOR WOUND DRESSING
Lactobacillus plantarum has been increasingly studied and applied in the context of wound healing and wound dressings, thanks to its antimicrobial, anti-inflammatory, and biofilm-disrupting properties. In some approaches, lyophilized (freeze-dried) L. plantarum is applied as a powder or mixed with a carrier to facilitate topical delivery. L. plant...

THE RELATIONSHIP BETWEEN RIGIDITY, PERFECTIONISM AND MENTAL HEALTH
Rigidity is one of the oldest psychological constructs to which, today, in the literature, traits such as egocentrism, authoritarianism, obsessiveness, inflexibility, and similar are associated. From the psychiatry's point of view, a rigid person is not a sick person, but a normal, healthy person with a special personality trait. The aim of this st...

THE VALUES AND ATTITUDES AS A DRIVERS OF ORGANIC FOOD PURCHASE
Values are one of the fundamental concepts that explain the human behavior, both individually and socially (Slijepčević & Matanović, 2015). Attitudes and values can greatly influence and guide our decisions and behavior. The aim of this research was to determine how attitudes and values about organic food can influence the decision to purch...
