Hen eggs represent a biologically rich matrix providing essential nutrients and bioactive compounds vital for embryonic development. Among these, immunoglobulin Y (IgY) and lysozyme play roles in passive immune defense and antimicrobial protection during early ontogenesis. Conventional heat treatments and digestion degrade these bioactive compounds, particularly IgY, which is thermolabile above 45 °C and unstable in acidic gastric conditions. To preserve these compounds, OVOIMUNO products employ freeze-dried techniques with carbohydrate stabilization, ensuring bioavailability and functional efficacy within the intestinal environment. These preparations facilitate targeted delivery and enhanced interaction of bioactive compounds with the gut microbiota, promoting beneficial microbial modulation and intestinal homeostasis. In vitro studies evaluating the viable cell and metabolic responses of probiotic strains to OVOIMUNO demonstrated pronounced prebiotic and postbiotic effects. The present study aimed to comprehensively assess the prebiotic potential of the OVOIMUNO supplement by investigating its influence on the growth kinetics of selected beneficial gut microorganisms and the subsequent production of key short-chain fatty acids, specifically propionic and acetic acids. By monitoring microbial proliferation and metabolite profiles, this work provides insights into the functional effects of OVOIMUNO on gut microbiota modulation and its potential contribution to host health.

Starting from the primary representation of neutrosophic information, namely the degree of truth, degree of indeterminacy and degree of falsity, we define a nuanced representation in a penta valued fuzzy space, described by the index of truth, index of falsity, index of ignorance, index of contradiction and index of hesitation. Also, it was constructed an associated penta valued logic and then using this logic, it was defined for the proposed penta valued structure the following operators: union, intersection, negation, complement and dual. Then, the penta valued representation is extended to a hexa valued one, adding the sixth component, namely the index of ambiguity.

I propose an integrated multiplexer/demultiplexer that use a concave blazed diffraction grating on SiON wafer. The paper presents a technology that overcome existing issues regarding implementation of such a microoptic device. Two types of similar integrated systems were developed but both of them have not minimized chromatic, astigmatism and spherical aberrations. Both systems use gold coating for vertical walls of diffraction grating that has reflection index lower than aluminum for wavelength used. Technology proposed in this paper minimizes the chromatic, astigmatism and spherical aberrations. Also is used aluminum for coating of vertical walls of diffraction grating. SiON wafer is etched with Argon plasma through photoresist mask with thickness of 0,8 μm for grating configuration allowing reusing of the photoresist in next stage of coating. This makes possible that coating through liftoff to be aligned to vertical walls of concave diffraction grating, eliminating positioning errors due to coating mask.

The fiber optic transmission systems have been used extensively for obtaining communication and intercommunication links within the public telephonic network, but lately the fiber optics has entered the vehicles field. The cable method might imply low costs if the coupling of the transducers to the optical fiber is optimised from the point of view of cost and fiability. The paper presents several methods of the optical fiber coupling, implying a glass or a plastic optical fiber, based on modern optical devices produced by Infineon.

The Wei method of constructing trellis codes with 2N-dimensional rectangular signal constellations is limited to N being an integer power of two. In the present correspondence, this limitation is removed and examples of six-dimensional (6-D) and twelve-dimensional (12-D) trellis codes are given.
