Skuteczność doświadczenia liturgii
2020
Artykuł podejmuje zagadnienie skutecznego oddziaływania liturgii na jej uczestników i w ogóle stykających się z nią, uwypuklając jej ewangelizacyjne i formacyjne skutki. W szczególny sposób uwzględniono w nim znaczenie piękna liturgicznych celebracji, jak również kwestie związane z tzw. participatio actuosa. Zasadniczą bazę źródłową artykułu stanowią publikacje takich wybitnych teologów, jak: J. Ratzinger, R. Guardini oraz J.A. Jungmann. Analiza ich refleksji zachęca do nowego odkrywania istotnej roli liturgii, zwłaszcza liturgii niedzielnej Mszy św. − jako najważniejszego wydarzenia w religijnym życiu chrześcijanina na przestrzeni tygodnia, a także do ukazywania wartości doświadczenia litu…
Technical English for agriculture
2021
As the world goes global, the agricultural business needs to move across frontiers and oceans. Food, raw and processed, is regularly transported across continents. As space is no longer a limit for food trade and human nutrition, language cannot represent a barrier to this continuous exchange. In the last 60 years, English has been taking a foothold as the primary language for world trade and the exchange of agricultural goods is no exception. Agricultural sciences embrace a large number of disciplines, from botany to environmental physiology, from soil science to meteorology, from plant propagation to cultural management, from soil management to pest control, from field crops to animal husb…
Drug Delivery in Plants: Targeted Drug Delivery in Plants: Enzyme-Responsive Lignin Nanocarriers for the Curative Treatment of the Worldwide Grapevin…
2019
In article number 1802315, Jochen Fischer, Frederik R. Wurm, and co‐workers report the first nanocarrier‐mediated drug delivery in plants. Enzyme‐degradable lignin nanocarriers are injected into the trunks of grapevine plants. They release a fungicide selectively inside of the plants and are able to cure the worldwide fungal plant disease Esca for the first time. This strategy will reduce the extensive spraying of pesticides in agriculture. Image credit: Katharina Maisenbacher.
Wetland Restoration with Hydrophytes: A Review
2021
Restoration cases with hydrophytes (those which develop all their vital functions inside the water or very close to the water surface, e.g., flowering) are less abundant compared to those using emergent plants. Here, I synthesize the latest knowledge in wetland restoration based on revegetation with hydrophytes and stress common challenges and potential solutions. The review mainly focusses on natural wetlands but also includes information about naturalized constructed wetlands, which nowadays are being used not only to improve water quality but also to increase biodiversity. Available publications, peer-reviewed and any public domain, from the last 20 years, were reviewed. Several countrie…
Fracture and fatigue of titanium narrow dental implants: New trends in order to improve the mechanical response
2019
Sixty-four fractured commercially pure titanium (cp-Ti) narrow dental implants (NDIs) with similar macrogeometry and connection designs were studied after different implantation times in humans in order to determine their reliability and to evaluate the causes of the fracture. These NDIs were compared with other similar implants, made with alloyed titanium with 15% Zr and with 12% strained titanium. Original implants were tested under static and fatigue conditions, simulating the tri-axial loads in the mouth by means of a Bionix hydraulic test machine. Fractography was studied using field-emission scanning electron microscopy (FSEM). The results showed that cp-Ti NDI exhibits low strength f…
A New Pt(II) Complex with Anionic s-Triazine Based NNO-Donor Ligand: Synthesis, X-ray Structure, Hirshfeld Analysis and DFT Studies
2022
The reaction of PtCl2 with s-triazine-type ligand (HTriaz) (1:1) in acetone under heating afforded a new [Pt(Triaz)Cl] complex. Single-crystal X-ray diffraction analysis showed that the ligand (HTriaz) is an NNO tridentate chelate via two N-atoms from the s-triazine and hydrazone moieties and one oxygen from the deprotonated phenolic OH. The coordination environment of the Pt(II) is completed by one Cl−1 ion trans to the Pt-N(hydrazone). Hirshfeld surface analysis showed that the most dominant interactions are the H···H, H···C and O···H intermolecular contacts. These interactions contributed by 60.9, 11.2 and 8.3% from the…
Plasmacytoid myoepithelioma of the palate : report of one case and review of the literature
2007
Introduction: Myoepithelioma is a benign neoplasm of salivary glands, represents 1.5 % of all salivary glands neoplasm. The plasmacytoid myoepithelioma from palate salivary glands is considered as a rare entity, at date it has been reported 14 cases. It is present one case of plasmacytoid myoepithelioma of palate. Case report: A Hispanic female of 28 years old presented a not-ulcerate, painless ovoid swelling at left side of hard palate with a one year and a half of evolution. An excisional biopsy was done. The sample was fixed at 10% buffer formalin, embedded in paraffin, cuts at 5 µ and stained with H-E. Microscopically, the lesion was composed by myoepithelial neoplastic cells characteri…
Obraz mniejszości niemieckiej w opolskiej prasie lokalnej w czasie tranzycji i w pierwszej fazie transformacji ustrojowej (1989-1992)
2022
The aim of the paper is an attempt to recreate the process of the emergence of the German minority movement in the period of the political transition in the years 1989-1992 on the basis of materials from the Opole daily press. The choice of this period is dictated by the desire to show the initial stages of development of this community and its organizational form. It was during the period in mention that the German minority not only expanded the territorial range of its organizational structures and profiled its activities, but most of all it outlined the scope of its influence on the social and political life at the local and regional level in the Opolskie Voivodeship. The processes that …
Deep and Proximate Determinants of the World Income Distribution
2019
This paper studies the deep and proximate determinants of the evolution of the cross-country distribution of GDP per worker in the period 1960–2008 by a novel method based on an information criterion. We find that countries of our sample follow three distinctive growth regimes identified by two deep determinants, namely life expectancy at birth in 1960 and the share of Catholics in 1965, and that each regime is characterized by non-linearities. Growth regimes appear to be the main cause of the increased inequality and polarization, while technological catch-up, proxied by the initial level of GDP per worker, acts in the opposite direction. Finally, human capital marginally reduces polarizat…
