This paper examines the use of multisensory virtual reality (VR) as a novel approach in psychological therapy for autobiographical memory retrieval with benefits for cognitive enhancement, stress reduction, etc. Previous studies demonstrated improved outcomes in treating various psychological conditions (affective disorders and PTSD). Technological advancements in VR, such as olfactory integration, can contribute to the realism and therapeutic potential of these environments. The integration of various physical stimuli with VR holds promising potential for psychological therapies and highlights the need for further interdisciplinary research. In this pilot study, we tested the efficacy of a new system for triggering autobiographical memory retrieval. For this, we used images combined with odors in a congruent manner and offering participants the chance to interact with the VR environment by using two virtual hands. We evaluated the efficacy of this system using qualitative methods, with emphasis on the evaluation of the emotions associated with memory recollection and the ease of triggering memories. All participants in our pilot study experienced intense emotions related to childhood or adolescence, and the pleasant feelings they had during the experiment persisted even after it ended. This is an advancement to what exists currently and provides original research elements for our paper. [ABSTRACT FROM AUTHOR]

Through his poetry, Codruț Gabriel CANTEA (first year cadet, CBRN Defense at the "Nicolae Bțlcescu" Land Forces Academy of Sibiu) checks the pulse of today's world and being. His verses denote the understanding of the world as a living organism, not just in its anatomy, but also in its physiology. The poetic deliveries in homeopathic doses are intended for the soul and mental genome and are related to his readers. Because he knows that one writes and reads in order to preserve the human essence. Creator of lyrical universe, with the poetic grace conceived in blood, he concentrates, in internal combustions, as well as in initiatory, catalytic utterances - experiences, views and existential guidance. And he traces poetic interior and exterior territories in which he settles (and settles his readers as well) empathetically and comprehensively with regard to the course of the world.

The Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy was applied for the evaluation of specific patterns for six different essential oils obtained from aromatic plants (thyme, oregano, tea tree) or common spices (clove, cinnamon, juniper). The spectral fingerprints were recorded using a Shimadzu IR Prestige-21 spectrometer in the middle infrared region (3500-650 cm-1) before and after thermal oxidation in hot air. In parallel, the peroxide index, cis-trans isomerization and lipoperoxidation were evaluated to determine their oxidative stability. Each oil showed specific FTIR spectra, especially in the fingerprint region (1650-650 cm-1), in good agreement with our previous GC-MS analysis of the same samples. The spectral patterns in this region were also correlated with their oxidative stability, chemically determined. The spectral data were processed by multivariate analysis (Metaboanalyst 5.0 software) and the discriminatory analysis helped to identify each oil pattern. This study combined the capability of ATR-FTIR-MIR spectroscopy to realize a pattern recognition of essential oils as a rapid and non-destructive method, as well the oxidative modifications, easier than chemical routine tests. This study contributes to the control of quality, authenticity, and safety of essential oils and can be extended to other extracts, used as additives or ingredients in food or cosmetic products.

The additive manufacturing known also as "3D printing" or "rapid prototyping" is a present manufacturing method (compared to classic manufacturing methods) where layers of material are deposited at a time (successively) until a finished product is obtained. Depending on the phenomenon, material (in solid, liquid or powder state) used by the 3D printing equipment, a solid part, can be achieved using processes as: binder jetting, extrusion, material jetting, direct energy, vat photo-polymerization and powder bed fusion. In the present paper, we have summarized some knowledge regarding the 3D printing technologies, fused deposition modeling (FDM) prototyping method, and different types of test regarding PLA material properties (tensile test, flexural test). The FDM technology has registered benefits as cost, product quality, functionality and manufacturing time, continuously optimized and adopted by more and more companies, research institutes and consumers.
