The article analyses the effects of paper moisture content on energy absorbed during its tensile testing in the range of moisture equilibrium obtained during paper air conditioning at a temperature of 23°C. To predict changes in breaking energy caused by changes in moisture content, two calculation methods were proposed. The methods were verified on the basis of laboratory tests and calculation results, and their practical usefulness was confirmed.

Background: Associated reactions (ARs) are involuntary movements that significantly affect the functioning of stroke patients. Due to a lack of scientific evidence, physiotherapists provide ARs therapy based mainly on individual experience. This common phenomenon remains poorly recognized among neurologists. Aims:The aim was to assess the relationship between patient's ability to independently change positions within the bed and the occurrence of upper limb ARs in the rehabilitation process in the acute phase of ischemic stroke. Material and methods:Group of 53 patients after an acute ischemic stroke underwent physiotherapeutic examinations. On the first day of the physiotherapy evaluation, the patient's ability to independently change positions within the bed was assessed. During the rehabilitation process, occurrence of the upper limb ARs was evaluated using the modified Associated Reaction Rating Scale (ARRS). Results:It was reported that 20.75% of patients presented ARs of the upper limb during the rehabilitation process. Significant differences were found between patients with and without ARs when comparing the ability to shift to a long sitting position and to rotate on to the more affected side, examined on the first day of physiotherapy assessment.Conclusions: Assessment of the patient's ability to change positions on the first day of physiotherapy can provide information that could help predict the occurrence of ARs. There is a need to adjust the ARRS for use in the acute phase of stroke. It is necessary to promote knowledge about ARs among neurologists and neurosurgeons.

Methods of removing arsenic compounds from natural gas and accompanying water to meet environmental requirements are discussed. Purification methods to remove arsine are evaluated and some are given preference. Data about process emissions from existing technologies are adopted. Most interesting patents including pyrolysis, adsorption, and absorption are listed. Potassium permanganate method is chosen as the most appropriate method to remove arsenic compounds from natural gas. Batch process to treat reservoir water and to regenerate the aresenic-saturated solutions and suspensions of potassium permanganate is recommended. The chemistry and thermodynamics of water conditioning process is presented.

The Jesuit Faculty of Philosophy in Cracow has existed since 1934, when it was erected by the Congregation for Seminaries and Universities. For the first 55 years it educated only the Jesuits, but since 1989 it has been opened to the laity as well. A memorial book Philosophia Rationis Magistra Vitae was published to celebrate the 70th anniversary of the Faculty of Philosophy with special dedication to its Professors: Fr. Roman Darowski SJ, Fr. Piotr Lenartowicz SJ, and Fr. Stanislaw Ziemiański SJ. All of them have worked at the former Faculty of Philosophy which is now the Faculty of Philosophy of Ignatianum. In these past few years, Fr. Ziemiański and Fr. Lenartowicz have celebrated their 70th birthday, during this year Fr. Darowski will celebrate such jubilee. The book consists of two volumes. The first contains congratulatory letters from Provincials of the Polish Jesuits to the Jubilarians. It also contains a short history of the Jesuit Faculty of Philosophy in Cracow, and provides presentations of the professors celebrating their anniversaries.
