Authors: Butkiewicz Aleksander F. , Skowroński Artur 
Published: October 2024

Abstract
In this article, an analysis of the normal anatomy of the stomach of the common pheasant (Phasianus colchicus) is presented. The material covered 20 female common pheasants from poultry breeding. A necropsy of the deceased animals was performed, and then the stomachs were removed, analyzed, and measured for length, width, thickness of the walls, and characteristic anatomical features. The measurements were made using a caliper. The presented results include the stomach and proventriculus, focusing on their specificity, such as the strongly developed muscular membrane of the type II stomach, characteristic of granivorous birds, which reflects the diet of pheasants. In the discussion, the stomach structure of the pheasant was compared with other birds, emphasizing how diet influences the varied morphology of organs. These studies are preliminary and should be expanded to a larger group of animals, taking into account the aspect of sex. However, they constitute a basis for further development of the normal and comparative anatomy of the common pheasant.

Abstract
Headaches are one of the most common reasons why patients seek help in the emergency department, and alcohol consumption is a well-known cause. Wine, in particular, is associated with headaches not only due to its alcohol content but also due to the presence of polyphenols and biogenic amines such as tyramine, putrescine, and, notably, histamine. Wine consumption is on the rise around the world and is likely to be reflected in headache prevalence. Understanding the mechanisms underlying wine-induced headaches can help in their management and prevention Therefore, we provide a comprehensive review of the pathophysiology of wine induced headaches.

Published: October 2024

Red spinach leaf (Amaranthus tricolorÂ L.) has been well-proven to contain flavonoids that exhibit antioxidant activities. In this study, a comparison between maceration and ultrasonic methods has been carried out to evaluate the effect of these two methods on the level of red spinach leaf flavonoid. In this study, for maceration 1, 2, and 3 days while for the ultrasonic method 10-, 20-, and 30-minutes time duration have been used. The ratios of material and solvent were 1:5 and 1:10. The flavonoid content was determined with the help of a spectrophotometer at a maximum wavelength of 436.80 nm. The antioxidant activity was evaluated by the DPPH method to obtain the IC50. The result of the study revealed that the highest flavonoid content of 4.27 mgQE/g and antioxidant activity (IC50) of 110.47 ppm were obtained by an ultrasonic under conditions of 1:10 ratio and 30-minute extraction time. Results of the study suggested a significant difference (p<0,05) in the isolation of total flavonoid contents and antioxidant activities in the maceration and ultrasonic. In these two methods, ultrasonic was found to be more efficient than maceration because of minimum time, the highest flavonoid content and antioxidant activity could be obtained.

В статье рассмотрены типовые схемы аэрогазодинамики в тупиковых подготовительных выработках и аэродинамика става гибких шахтных вентиляционных труб при нагнетательном проветривании с помощью вентиляторов местного проветривания. Отмечено, что характер выделения метана по длине тупиковой выработки разнообразен и имеет различную интенсивность. Наибольшие утечки воздуха из вентиляционного става происходят у устья выработки, вблизи вентилятора, а по мере подвигания к тупиковой части они уменьшаются.Typical aerogasdynamics schemes for dead-end preparatory excavations and aerodynamics of a stack of flexible mine ventilation pipes during the forced ventilation with local fans are considered.It is noticed that the methane release along the length of the dead-end headings is varied and has different intensity. The biggest amount of air leakage from the vent stack occurs near the heading mouth, near the fan, and as it moves toward the deadlock. It decreases while moving to the dead-end part.

Abstract The article is devoted to the development of a method for determining of a flame speed according to signals of electro-optical flame detectors. Analytical dependencies are formulated for the calculation of the flame front speed by the time-of-flight method with the determination of the time delay by four methods: threshold method method on the basis of the cross-correlation function method based on the envelope correlation coefficient method based on cross-spectral density. The results of study of the proposed methods for accuracy of the time delay determining for the simulated noisy signals and for the characteristic experimental signals obtained by recording radiation of non-stationary combustion are presented. The method based on the cross-correlation function is optimal for the implementation of the system. The influence of the analysis time range of the detector signals on the error in determining the time delay was estimated. Criteria for selecting the lower and upper boundaries of the time window were formulated.
