Postulates and Proposals of Members of the Polish Government-in-Exile for Poland’s Economic Security in the Context of the Reconstruction of the State in 1944–1945: Selected Examples

The article aims to indicate selected, postulated directions of Poland’s economic recovery in the early years after World War II, considering the contribution made by the Polish Government-in-Exile (Government of the Republic of Poland in Exile). The analysis includes a query of archival documents from 1944–1945 and a review of scientific literature. The thesis has been put forward that the substantive developments from the years 1944–1945 prepared by the Government of the Republic of Poland in Exile may constitute a valuable cognitive source for the analysis of possible directions of reconstruction and development of the Polish economy after the destruction caused by the events of World War II. It has been shown that the Government of the Republic of Poland in Exile created numerous studies on the economic recovery of the country after World War II, even before the armed conflict formally ended. Many of the valuable guidelines referred to the reconstruction and development of the coal mining industry, oil industry, and forest management

Invasive species and their role in historic park sites

Invasive species are alien elements of flora and fauna to our environment, in each case their occurrence is a very serious threat to native organisms. Invasive insects damage trees of great significance in park sites. They face very little resistance from the environment and substantially affect the decorative character of plants. A well-known representative of the group of phytophages is Cameraria ohridella or Horse-chestnut leaf miner occurring on horse-chestnut. Recently, Phyllonorycter issikii was observed on lime trees, P. robiniella on Black Locust and P. platani on plane trees in the historical parks of the city of Rzeszów and its surrounding. Newly identified in Rzeszow and potentially dangerous pest of plane trees is also Corythucha ciliata, an insect in the Coreidae family. Another risk for trees and shrubs may be the Western conifer seed bug Leptoglossus occidentalis, which is more and more frequently observed in different parts of Rzeszów

Wczesna zakrzepica zastawki biologicznej w pozycji mitralnej

We present a case of a 70 year-old woman operated due to severe mitral regurgitation. Early after surgery transthoracic echocardiography revealed the decreased effective orifice area of the implanted bioprosthetic valve and the stenotic features of transvalvular flow. Transesophageal echocardiography (TEE) disclosed a thrombotic cause of heterograft dysfunction. Due to the clinical deterioration and the unclear cause of prosthesis stenosis, the patient was reoperated. Intra-operatively bioprosthetic mitral valve thrombosis was confirmed. Precipitating factors of this rare complication including cardiac devicerelated infective endocarditis (CDRIE) and the diagnostic applicability of TEE in this clinical scenario are discussed.We present a case of a 70 year-old woman operated due to severe mitral regurgitation.

Olbrycht T.: Historic Rzeszów parks as a mainstay of precious invertebrates

This research shows that historic parks in Rzeszów are inhabited by a significant number of interesting species of beetles. The most important group among them from the environmental and economic points of view are ground beetles, especially predatory species of the genus Carabus, legally protected. Rare and protected saproxylic beetles are represented by several species, of which Osmoderma eremita deserves special attention. Similarly, two species belonging to the family of Cerambycidae and Elateridae, rarely encountered in the Podkarpacie region, were identified in the parks of Rzeszów. Thus, the historic parks have become not only an important part of the landscape, but also contribute to the enrichment of biodiversity and to wildlife conservation

Pulse thermography measurements of heat dissipation from high power LED's

Authors focused on the research of heat dissipation problem in electronic devices. For this purpose, a series of thermovision measurements were carried out, and the object of the research was a high-power LED attached to a radiator. The thermal response in frequency domain was calculated. Gained data consisting of amplitude and phase values of the thermal response of the diode-radiator set-up during work allowed authors to estimate its cooling conditions, with particular interest set to the quality of thermal connection between the diode and radiator

Iatrogenic lumbar artery pseudoaneurysm after lumbar transpedicular fixation: Case report

Only a few cases of iatrogenic lumbar injury have been reported in the literature. A 58-year-old male with severe back pain was admitted to our department. The patient was qualified for the transpedicular stabilization with interbody fixation at L4/L5 and L5/S1 levels. On the first day after surgery, the patient was mobile and reported significant pain relief. He was discharged the same day. After 2 weeks, the patient returned with severe right lower abdominal pain and radicular pain in his right leg. He was administered to the Neurology Department where the presence of a lumbar muscle hematoma and lumbar artery pseudoaneurysm were discovered. He was transferred to the Vascular Surgery Department where aortography was performed and the pseudoaneurysm was embolized. After few days, the patient’s overall condition improved significantly. Eight weeks after surgery, he was pain-free. Our case shows how initially innocuous symptoms may be the result of serious complications

Gall Nuts <i>Cynips quercusfolii</i> (Linnaeus) and <i>Andricus infectorius</i> (Hartig) as Tannin Raw Materials

The study included gall nuts caused by Cynips quercusfolii collected from Quercus robur and Andricus infectorius, harvested from Quercus infectoria. The evaluation of the percentage content of tannins expressed as a pyrogallol was performed using the analytical methodology recommended by the current “European Pharmacopoeia 10”. In order to compare the chemical composition of the tested samples, chromatographic profiles and ion mass distribution spectra were made using high-performance liquid chromatography techniques coupled with two types of detection: spectrophotometry and mass spectrometry. The average content of tannins expressed as pyrogallol for C. quercusfolii ranged from 13.36% to 14.74%, while for A. infectorius it was from 34.77% to 39.95%. The comparison of both the mass spectra and the chromatographic profiles shows a high similarity of all samples of C. quercusfolii and large differences in the chemical composition compared to A. infectorius. The tested C. quercusfolii should be considered a much poorer tannin source than A. infectorius. It cannot be simultaneously treated as its substitute raw material due to the lower tannins percentage content and different chemical composition. However, compared to other Central European herbal raw materials, C. quercusfolii gall nuts are an alternative tannin source with potential use in herbal medicine and the pharmaceutical industry
