Recognition of the loess covers by using a resistivity imaging method

A main aim of research work was to recognize loess covers by geoelectrical method for three tipped areas, to define loess thickness and show their variability. Resistivity imaging method was used. To research chose Kańczuga Plateau, Nałęczów Plateau and Prydniestrov’ja region (Ukraine). There were used resistivity imaging methods, and the work results were corelated with geological documentation of the research area. The research showed variability in loess covers related to their stratigraphy and allow determine thickness loesses deposit

Coexistence of Ehlers–Danlos Syndrome with Coronary–Pulmonary Arterial Fistula and Other Multiple Coronary Artery Anomalies

This case report presents a 34-year-old male with Ehlers–Danlos syndrome, type 2 diabetes mellitus, aortic valve regurgitation, and aortic bulb aneurysm. Following spine surgery for thoracic–lumbar stabilization, the patient underwent assessment for aortic bulb aneurysm and aortic valve replacement surgeries. Five months post spinal surgery, a coronary computed tomography angiography was performed. The coronary computed tomography angiography revealed unique findings, including the absence of the left main coronary artery, right coronary artery dominance, ectopic origin of the left circumflex artery from the right sinus of the valsalva, a coronary–pulmonary arterial fistula originating from the right sinus of the valsalva, and an additional right pulmonary vein. The patient was qualified for surgical treatment for an aortic bulb aneurysm, was informed about the high surgical risk, and is awaiting surgery. This case underscores the rarity of Ehlers–Danlos syndrome coexisting with multiple coronary artery anomalies. The presence of a coronary–pulmonary arterial fistula further emphasizes the need for specialized patient monitoring when Ehlers–Danlos syndrome and coronary anomalies converge

The impact of residential development and municipal greenery on the thermal conditions of the city gullies in Lublin

Urbanization is a serious threat to the soil cover. It entailsthe process of soil sealing thereby limiting soil functions.The local climate is also affected – sealed areas absorb heat, thereforetemperature above them is increasing. It contributes to theformation of an urban heat island, which negatively affects thequality of human life. In the two surveyed gullies in Lublin, 35measurement points were located, in which two temperature sensorswere placed: one at a height of 1.5 m and the other in the soilat a depth of 0.15 m. The measurement points were located at differentdistances from the buildings (from 10 to 236 m in a straightline) and in the areas with different types of vegetation – trees,shrubs and grass. Research carried out in two gullies in Lublin revealedthat the differences in air temperature at various locationswere even 10 degrees Celsius depending on the distance from thebuildings, the type of plant cover and soil characteristics. Largetemperature variability could be observed even within a smallarea. The negative impact of buildings on the air temperature inthe city is eliminated by proper distribution of green areas, reducingthe temperature by up to 7 degrees Celsius. The process ofsoil sealing cannot be avoided. Therefore, land intended for urbanisationshould be used rationally. The spatial planning processshould take into account not only land for infrastructure but alsofor green areas to reduce negative impact of soil sealing on thequality of life of the residents
