Zaangażowane badania jakościowe – perspektywa autobiograficzna
2018
The presented article is an attempt to reconstruct/retrospect my professional biography in its methodological section. It is a description of the way I went to become a biographic, narrative scholar. It is also a description of the reasons – theories, concepts, discussions and disputes that accompanied me on the way. I present my critical attitude towards Polish school and Polish education, posing questions about education, school and teacher. The second matter that organizes my research is the question about interpersonal relationships, intimacy, marriage, family and what is happening between: spouses, partners, parents and children. I ask what in our relationships with others favours a ha…
Filtering out intersymbol interference in spread-spectrum communication systems
1979
In this letter the transfer characteristic of the optimum filter suitable for eliminating intersymbol interference in pseudo-noise spread-spectrum communication systems is determined. Such a characteristic is independent of the code sequence employed.
Flow-cytometric screening for the modulation of receptor-mediated endocytosis in human dendritic cells: implications for the development of an in vit…
1997
The aim of this study was to explore the usefulness of human blood dendritic cells (DC) in the development of an in vitro model for predictive testing of contact sensitizers. A method was established to monitor the influence of chemicals on the intracellular targeting of antibody-crosslinked MHC class II molecules after their uptake by human DC. Using a three-colour flow-cytometric technique, freshly prepared DC were distinguished from other MHC class II-bearing cell types such as B-cells and monocytes in unseparated mononuclear cell suspensions of healthy volunteers. The assay is based on the pH-sensitivity of internalized fluorescein-coupled MHC class II specific antibodies. Quenching of …
A New Fitness Test of Estimating VO2max in Well-Trained Rowing Athletes
2021
BackgroundThis study was designed to investigate the validity of maximal oxygen consumption (VO2max) estimation through the Firstbeat fitness test (FFT) method when using submaximal rowing and running programs for well-trained athletes.MethodsWell-trained flatwater rowers (n = 45, 19.8 ± 3.0 years, 184 ± 8.7 cm, 76 ± 12.9 kg, and 58.7 ± 6.0 mL⋅kg–1⋅min–1) and paddlers (n = 45, 19.0 ± 2.5 years, 180 ± 7.7 cm, 74 ± 9.4 kg, and 59.9 ± 4.8 mL⋅kg–1⋅min–1) completed the FFT and maximal graded exercise test (GXT) programs of rowing and running, respectively. The estimated VO2max was calculated using the FFT system, and the measured VO2max was obtained from the GXT programs. Differences between the…
Sacred Music Production and Circulation in Sixteenth-Century Palermo: The Inventories of Giovanni Santoro (1550) and Luis Ruiz (1595)
2016
L'importanza degli inventari per lo studio della vita musicale a Palermo è stata riconosciuta soltanto di recente. Nonostante la natura frammentaria dei dati, questi documenti forniscono informazioni di rilievo sulle edizioni musicali, sugli strumenti, sulla cultura materiale che li produceva, nonché sulla circolazione della musica. Considerata la mancanza di testimoni musicali siciliani tra Cinque e Settecento, tale importanza appare ancor più evidente. Difatti, gli inventari palermitani testimoniano la presenza di libri di musica non più esistenti, in particolare musica a stampa, ma anche manoscritti e libri liturgici. L'articolo si sofferma su due inventari del Cinquecento. Il primo è l'…
Electronic and Magnetic Properties of Li<sub>1.5</sub>Mn<sub>0.5</sub>As Alloys in the Cu<sub>2</sub>Sb Structure
2013
We investigated two formula-units of Li1.5Mn0.5As alloys, such as Li3MnAs2, in the Cu2Sb crystal structure using an ab-initio algorithm. By interchanging Mn with each Li located at different positions of the Li4As2unit cell, four separate alloys are formed. At the optimized lattice constant, two of these alloys are predicted to be ferromagnetic metals and the other two are half metals. The possibility of half metallicity in the first two is also explored. Both the modified Slater-Pauling-Kübler rule and the ionic model can characterize the magnetic moments of the half metals.
Combined inguinal hernia in the elderly. Portraying the progression of hernia disease
2016
Abstract Introduction Identification of a combined hernia is a common occurrence in the course of inguinal hernia repair. This type of protrusion disease seems to affect the elderly, in particular. Very few investigations have been carried out to ascertain the structural changes that occur in the groin affected by this clinical condition. Method Analysis of intraoperative findings of combined inguinal hernias evidenced in the elderly, from the most recent 100 groin hernia repair procedures carried out by a single operator, represents the basis of the article. Protrusions that presumably represent the forerunner of this type of hernia were also analyzed: double ipsilateral inguinal hernias c…
Effects of chronic exercise on myocardial refractoriness: a study on isolated rabbit heart
2008
Aim: To determine whether chronic physical training increases atrial and ventricular refractoriness in isolated rabbit heart. Methods: Trained rabbits were submitted to a protocol of treadmill running. The electrophysiological parameters of refractoriness investigated in an isolated heart preparation were: (1) atrial effective refractory period (AERP) and atrial functional refractory period and ventricular effective and functional refractory periods (VERP and VFRP) using the extrastimulus technique at four different pacing cycle lengths; (2) the dominant frequency (DF) of ventricular fibrillation (VF). A multi-electrode plaque containing 256 electrodes and a spectral method were used to o…
