Giant superconducting proximity effect on spintronic anisotropy

We investigate theoretically the interplay of proximity effects due to the presence of a superconductor and normal ferromagnetic leads on the formation of the spintronic quadrupolar exchange field in a large-spin molecule. We show that the spintronic anisotropy can be enhanced by a few orders of magnitude, and tuned by changing the strength of coupling to the superconductor. Especially large anisotropy is generated in the vicinity of the charge parity changing transition of the molecule. We also provide predictions of measurable spectral properties being the hallmarks of these phenomena.Comment: Published version, 16 pages, 13 figures (including appendices

Prediction of swell pressure in Neogene clays from Warsaw, based on the swell index

The paper presents the results of swell measurements of Neogene clays (Posnanian clay) from the Mazovia region with different grain size distribution and mineral composition. The study was conducted with model soil with initial moisture contents of 15%, 20%, 25% and 30%. The basic physical properties of clays, their mineral composition and swelling parameters such as free swelling index and swelling pressure were determined. Free swell index was correlated to liquid limit, plasticity index, clay content and water content. A very high fit was found for a proposed relationship between the free swell index and swell pressure which offers an inexpensive method of predicting swell pressure in the preliminary stages of site investigation

Post-traumatic diaphragma hernia

W niniejszym artykule przedstawiono przypadek 22-letniego mężczyzny z pourazową przepukliną przeponową, do powstania której doszło w następstwie tępego urazu klatki piersiowej i nadbrzusza. Na podstawie przeprowadzonych badań diagnostycznych rozpoznano pourazową przepuklinę przeponową lewostronną. Chorego operowano w trybie planowym. W trakcie laparotomii stwierdzono rozerwanie lewej kopuły przepony, przez które żołądek został w większej części przemieszczony do klatki piersiowej. Żołądek odprowadzono do jamy brzusznej i wykonano plastykę przepukliny pourazowej przepony, zeszywając ją przy rozprężonym płucu. W przebiegu pooperacyjnym wystąpiła odma opłucnowa lewostronna, którą leczono, wykonując drenaż lewej jamy opłucnowej. Drenaż usunięto w 4. dobie po operacji, po uzyskaniu upowietrznienia dolnego pola lewego płuca. Pacjenta wypisano z kliniki w 5. dobie po operacji w stanie dobrym.A case of a 22 year-old male with post-traumatic diaphragmatic hernia resulting from a blunt injury of chest and epigastrium is presented. Based on diagnostic procedures, left-sided posttraumatic diaphragmatic hernia was diagnosed. A scheduled surgical procedure was performed in the patient. A laparotomy revealed a rupture of the left diaphragmatic dome which allowed the displacement of the major part of the stomach to the thoracic cavity. The stomach was replaced in the abdominal cavity and a hernioplasty was performed by suturing the diaphragm while keeping the lungs expanded. During the postoperative course, left-sided pneumothorax occurred which was treated with left thoracic cavity drainage. The drain was removed on the fourth day after the operation when aeration of the lower field of the left lung was achieved. The patient was discharged in good condition on the fifth day after operation
