  • Vitamin A is a group of substances close in chemical structure, they are retinol (vitamin A1, axerophytol) and other retinoids with similar biological activity: dehydroretinol (vitamin A2), retinal (retinen, vitamin A1 aldehyde) and retinoic acid. Provitamin A includes carotenoids, the metabolic precursors of vitamin A; β-carotene is the most important among them. Retinoids are found in animal-derived foods, while carotenoids are found in plant-derived foods. All these substances are very soluble in non-polar organic solvents (for example, oils) and poorly soluble in water. Vitamin A is stored in the liver and can be stored in tissues. It is toxic in cases of overdose.

  • It was determined that 150-350 tons of fibrous waste, 5-6 tons of non-recyclable waste, 70-90 percent of non-recyclable waste are organic waste per year depending on the type of cotton. In agriculture, it serves as a raw material for the use of waste as animal feed. This article describes the variation of fiber waste from the technological stream in cotton ginning plants, how it varies during the stages of the technological process. The dust released in the drying and cleaning shop is 5-7 mg/m3 of dust, which is less than the air in the building where the drying equipment is located. Large scattered dust particles are separated even in high humidity and sink to the surface of the building without being able to disperse. In drying devices, the dust released together with the atmospheric drying agent causes discomfort. Although this dust is coarsely dispersed, it escapes with the air flow in the dryer and settles near the roof of the building and near the drying room. It was determined that the amount of dust produced is 500-600 kg per day. The dust released at the cotton ginning station is released into the atmosphere in the air in the cotton drying and cleaning shop, as well as in the cleaning of cotton gins by the cotton pneumatic transport system. It is a powdered fiber with less mineral fractions. Fine fractions mainly consist of crushed dirty particles.

  • Due to the steady increase in cervical cancer neglect rates and, as a result, the occurrence of relapses and metastases, the possibilities of widespread introduction of systemic chemotherapy (platinum-containing regimens) in programs of combined and combined radiation treatment of primary and metastatic cervical cancer are being studied. Reducing the volume of the tumor due to chemotherapy not only leads to an increase in the effectiveness of radiation therapy, but also provides a selective possibility of surgical treatment of localized recurrences and metastases of cervical cancer to increase the duration and quality of life.

  • Players who have participated in regular training from a young age are preparing for professional or amateur level competitions. The training (competition) carried out over many years and the contribution of these trainings are studied and reported by scientists. At this point, we believe that our research can contribute to the development of young players through scientifically based additional training by coaches or individual players. In this study, it is important to observe and evaluate the effects of different training methods used in addition to the training of young football players on aerobic, anaerobic parameters and respiratory parameters.
