This study focuses on the characterization of the macro-biochemical composition of leaves of Pistacia lentiscus L. from 11 natural populations in Morocco, in order to allow genetic differentiation of this species. This characterization of the studied population allows research and identification of the most informative markers and analysis of relatedness between populations and their origin sites. The results of ANOVA showed that there were significant differences (p = 0.05) in total sugar content, dry matter content and fiber content between the studied populations. Organic matter, dry matter and total nitrogen contents were positively and significantly correlated with energy values (r = 0.92 and 0.962). In contrast, negative significant correlations were found between dry matter, minerals, fat content and carbohydrates (r = -0.217, -0.379). The results of principal component analysis showed that the 11 studied populations were dispersed among four groups, regardless of their geographical proximity. This grouping is confirmed by hierarchical classification.

Understanding the changing levels of biochemical parameters and the factors that influence them throughout the seasons is crucial for comprehending the dynamics of marine ecosystems. It also helps us identify potential threats that could harm their condition, aiding decision-making processes related to their protection. This study focuses on examining the variations in nutrients (such as nitrates, phosphates, and silicates), dissolved oxygen, and phytoplankton within the Gulf of Gdańsk. Additionally, we analyze the primary production process at three representative locations. To achieve this, we used data from the EcoFish biochemical numerical model. To ensure the model's accuracy, we compared its results with in situ data from the ICES database. The comparison revealed high correlations and minimal errors. Furthermore, we investigated how limiting factors impact primary phytoplankton production and demonstrated how the intensity of spring diatom blooms influences the nature of cyanobacterial blooms in the summer.

The effects of low frequency vibration exposure on the humans were investigated in the Institute of Human Biophysiology of the Academy of Physical Education in Kraków. The research program involved nineteen 1200 s vibrations exposure sessions in the subsequent working days, at the same time of day for each participant. During each session, selected physiological parameters were registered before and after the exposure, the heart beat rate HR and saturation levels SpO2 were monitored on the constant basis. The research program was supported by the biochemical and densitometric analysis before and after the experiments.

Badania wpływu drgań niskoczęstotliwościowych odbyły się w Instytucie Biofizjologii Człowieka AWF w Krakowie. Eksperyment obejmował dziewiętnaście 20-minu-towych ekspozycji drganiami (nazywanych dalej treningami), w kolejnych dniach roboczych o stałej porze dnia dla każdej osoby. W trakcie każdego tre-ningu rejestrowano wytypowane parametry fizjologiczne przed i po tre-ningu, prowadzono stały monitoring pulsu HR i saturacji SpO2. Przed eksperymentem i po jego zakończeniu przeprowadzono badania biochemiczne.

The effects of infrasound exposure were investigated at the Institute of Human Bio-physiology of the Academy of Physical Education in Kraków. The research program involved nineteen 20 min vibrations exposure sessions in the subsequent working days, at the same time of day for each participant. During each session selected physiological parameters were registered before and after the exposure, the heart beat rate HR and saturation levels SpO2 were monitored on the constant ba-sis. The research program was supported by the biochemical analysis before and after the experi-ments.

The aim of the research is to analyze the changes of selected biochemical parameters and strength bones of rats under exposure to low-frequency vibrations. Experiments were run on 30 Wistar rats randomly divided into three groups: the first group was first exposed to vibrations when rats were 20 days old (_20)(before puberty), the second group was subjected to vibrations from the 70th day on (_70)(after reaching puberty), the third is the control group (_K). On the 145th day the rats' ((_20) and (_70)) bones were subjected to biochemical examination and strenght bones.
