Stick around: Cell–Cell Adhesion Molecules during Neocortical Development
2021
The neocortex is an exquisitely organized structure achieved through complex cellular processes from the generation of neural cells to their integration into cortical circuits after complex migration processes. During this long journey, neural cells need to establish and release adhesive interactions through cell surface receptors known as cell adhesion molecules (CAMs). Several types of CAMs have been described regulating different aspects of neurodevelopment. Whereas some of them mediate interactions with the extracellular matrix, others allow contact with additional cells. In this review, we will focus on the role of two important families of cell–cell adhesion molecules (C-CAMs), classi…
Speciation of organotin compounds in NaCl aqueous solution. Interaction of mono-, di- and triorganotin(IV) cations with nucleotides 5’ monophosphates
2004
Formation constants for complex species of mono-, di- and tri-alkyltin(IV) cations with somenucleotide 5-monophosphates (AMP, UMP, IMP and GMP) are reported, atT=25◦CandatI=0.16 mol l−1(NaCl). The investigation was performed in the light of speciation of organometalliccompounds in natural fluids in the presence of nucleotides whose biological importance is wellrecognized. The simple and mixed hydrolytic complex species formed in all the systems investigatedin the pH range 3–9 are (L=nucleotide; M=organotin cation RxSn(4−x)+, withx=1to3):ML+,ML(OH)0and ML(OH)2−for the system CH3Sn3+–L (L=AMP, IMP, UMP); ML0and ML(OH)−for the system (C2H5)2Sn2+–L (L=AMP, IMP, UMP); ML−, ML(OH)2−,MLH0and M2L(O…

Szczegóły konstrukcyjne organów Paula Voelknera na przykładzie unikalnego katalogu firmowego z 1900 roku
2018
This article presents a unique advertising brochure dating from 1900 which was published by the organ building company Voelkner from Duninów and which has been discovered in the State Archives in Wrocław in the files of the Silesian Evangelical Consistory. The catalogue contains 47 pages and is a valuable source for the history of the Voelkner company. By studying this publication, the reader will get acquainted with the trends prevailing in the field of organ building at the turn of the 19th to the 20th centuries. However, the advertising folder does not contain any listing of the works realized by the company, which is probably its greatest shortcoming.
Organy na Śląsku Opolskim na łamach „Zeitschrift für Instrumentenbau”
2021
Periodicals remain a valuable source of information about the history of Silesian organ building. Particularly from the nineteenth century on, numerous publications appeared in the general press that were dedicated to music and the various manifestations of musical life including issues from the field of instrumentology. Professional periodicals dealing with this topic also started to appear. The periodical “Zeitschrift für Instrumentenbau”, which was founded by Paul de Wit in 1880 and appeared until 1943, certainly belonged to this group of publications. It devoted much space to the issues of organ building. Starting from the thirteenth year of publication, it included even a permanent sec…
Organy - instrument, który "oddycha"
2016
Artykuł omawia organy jako instrument z rodziny aerofonów. Punktem wyjścia do przeprowadzenia analiz jest niewielka tabliczka informująca kalikanta o należytym wykonywaniu pracy, która znajduje się na chórze muzycznym kościoła parafialnego pw. Najświętszego Serca Pana Jezusa w Roszkowie (pow. Racibórz). Tego rodzaju instrukcje były typowe dla organów pochodzących z warsztatu organmistrzowskiego Schlag & Söhne. W artykule omówiona jest funkcja kalikanta. Artykuł stawia tezę o konieczności przywrócenia organom ich „aerofoniczności”. Przedłożone zostały trzy postulaty końcowe: 1) Należy wyposażać nowo budowane organy w mechanizmy do kalikowania — uzupełnieniem zaś tego rodzaju urządzeń powinny…
Polska bibliografia organów prof. Marii Szymanowicz jako narzędzie badań organoznawczych
2020
The above article presenting Polska bibliografia organów published since 2011 by Prof. Maria Szymanowicz, also partly captures the reaction to the published work of musicologists and organologists as well as bibliographers. It is also an attempt to justify that the publication, even if not free from methodological shortcomings and small deficiencies, is still a valuable, useful and even necessary tool in the hands of Polish researchers on subjects related to organs. The presented article consists of four points, introduction, ending and bibliography list. The first point discusses the substantive value of the so-called domain bibliographies, which from the bibliographers’ point of view are …
Theoretical and computational studies of magnetic anisotropy and exchange coupling in molecular systems
2018
The field of molecular magnetism studies the magnetic properties of molecular systems as opposed to conventional metal-based magnets. The high chemical modifiability of the constituting molecules makes such materials highly versatile, and the small size of the building blocks leads to the rise of various quantum mechanical phenomena, such as tunneling and entanglement. These phenomena can then be further utilized in the construction of nanoscale quantum devices. This dissertation describes computational and theoretical studies in the field of molecular magnetism using state-of-the-art quantum chemical methods based on ab initio multireference approaches and broken symmetry density functional t…
