Analiza rozrzutu pocisków wystrzelonych z pistoletu maszynowego Glauberyt

Within an enclosed shooting range of the EMJOT company, the process of firing one hundred single bullets from a Glauberyt machine pistol was recorded. The empirical test used 9x19 mm FMJ Luger (Parabellum) ammunition manufactured in the Czech Republic in 2017. As the weapon is dedicated to special forces, the shots were fired by an anti-terrorist operative, at a target located 25 m away. In order to determine bullet dispersion, the results of the experiment were subjected to statistical processing. Mean displacement and mean square displacement relative to the mean hit point, histograms, normal distribution, as well as statistical tests and hypotheses were used for estimation. The shots were recorded with a high speed digital camera Phantom v 9.1. The videos recorded were used to determine the initial kinematic parameters of the bullet trajectory.Na zamkniętej strzelnicy firmy EMJOT przeprowadzono rejestrację procesu wystrzelenia z pistoletu maszynowego Glauberyt ogniem pojedynczym stu pocisków. Do badań empirycznych użyto amunicję 9x19 mm FMJ Luger (Parabellum) produkcji czeskiej z 2017 roku. Ze względu na dedykowanie broni dla oddziałów specjalnych strzały oddane zostały przez antyterrorystę, do tarczy znajdującej się w odległości 25 m. W celu określenia rozrzutu pocisków wyniki eksperymentu poddano obróbce statystycznej. Do estymacji zastosowano uchylenie średnie i uchylenie średnio-kwadratowe względem średniego punktu trafień, histogramy, rozkład normalny, oraz testy i hipotezy statystyczne. Przy wykorzystaniu szybkiej kamery cyfrowej Phantom v.9.1 przeprowadzono rejestrację wykonanych strzelań. Zarejestrowane filmy posłużyły do określenia początkowych kinematycznych parametrów lotu pocisku

Comparison of the Ventral Approach to the Canine Hip Joint Using Gelpi Retractors and an Elastic O-Ring Wound Retractor

This study included 10 fresh adult cadavers of large breed dogs (6 males and 4 females). Their weight ranged from 25 to 45 kg (mean ± SD: 33.9 ± 6.2 kg). The breeds represented were crossbreed dogs (n = 5), German shepherds (n = 2), Bernese mountain dogs (n = 1), American Staffordshire terriers (n = 1), and Gordon setters (n = 1). Access to the target area and identification of the femoral head and neck was achieved with two Gelpi retractors inserted orthogonally and with the O-WR in all procedures. In each dog, the approach to the hip joint was made on the left and right sides. There was no significant difference in the area of the surgical wound bed between the two sides using either the Gelpi retractors (−0.52 ± 1.87 cm2; CI 95%: −1.86, 0.81 cm2; p = 0.398) or the O-WR (−0.27 ± 2.34 cm2; CI 95%: −1.94, 1.41 cm2; p = 0.729). The area of the surgical wound bed was 6.28 ± 1.72 cm2 (2.72–9.70 cm2) for the Gelpi retractors and 6.34 ± 1.81 cm2 (4.13–10.77 cm2) for the O-WR, and the difference between the Gelpi retractors and the O-WR was not significant (−0.06 ± 1.72 cm2; CI 95%: −0.86, 0.74 cm2; p = 0.879

Patient with Phenylketonuria and Intellectual Disability—Problem Not Always Caused Exclusively by Insufficient Metabolic Control (Coexistence of PKU and Alazami Syndrome)

The authors present a case report of a boy with a classical form of phenylketonuria and Alazami syndrome. The inborn error of phenylalanine metabolism was diagnosed in the neonatal period based on population new-born screening. Despite early implementation of a low-phenylalanine diet and good biochemical control, the patient developed behavioural disorders and intellectual disability. He also presented with dysmorphic features. After long and extensive attempts to establish the genetic cause of this unusual phenotype, finally, at the age of 16 the boy was diagnosed with Alazami syndrome based on whole exome sequencing. The authors discussed the problem of neuropsychological disorders in patients with phenylketonuria and described typical clinical symptoms of Alazami syndrome. It was emphasized that the presence of one monogenic disease does not exclude the coexistence of another one
