Przeprowadzono ocenę procesu degradacji polietylenu (PE) w warunkach in vitro pod wpływem działania promieniowania rentgenowskiego (X) oraz inkubacji w dwóch roztworach symulujących środowisko żywego organizmu (SBF – simulated body fluid). W badaniach wykorzystano dawkę odpowiadającą 10 standardowym zdjęciom rentgenowskim układu kostnego oraz roztwory Ringera i soli fizjologicznej o temperaturze 40°C...
The reactions between o-vanillin and three isomeric aminopyridines lead to imines of diverse spatial conformation and reactivity. The direct products of these simple reactions carried out in methanol are either imine compounds formed in the reactions of 2-amino- and 3-aminopyridine with o-vanillin or the α-aminoether formed in the reaction of o-vanillin with 4-aminopyridine. The Schiff-type derivative...
This paper shows the results of a survey in which the environmental awareness of the inhabitants of one of the local government units of the Pomeranian Voivodeship – Słupsk County was examined. The aim of the study was to determine the state of the inhabitants knowledge in the field of environmental degradation, and to identify the local community opinion on proecological activities of the local government...
The present in vitro study investigated the influence of doxazosin on the contractility of the urinary bladder in female pigs with experimentally induced cystitis. Fifteen juvenile female piglets (18-20 kg body weight) were randomly assigned into three groups (n=5 animals each): i) control (clinically healthy animals, without doxazosin treatment), ii) animals with induced inflammation of the urinary...
Nierównomierność wschodów i wzrostu siewek na początku wegetacji jest jednym z podstawowych elementów zmienności plonów na plantacjach buraka cukrowego. Głównym czynnikiem ograniczającym produktywność roślin jest powolny wzrost powierzchni liści w tym okresie. Przyrost powierzchni liści można zwiększyć poprzez przyśpieszenie terminu siewu oraz wzrostu roślin w wyniku odpowiedniego przygotowania nasion...
